    [002] Factors influencing the deterioration of the freshness of vegetables include temperature, humidity, ambient gas, microorganisms and light. As respiration and perspiration occur on the surfaces of vegetables, to maintain the freshness of vegetables, it is necessary to reduce respiration and perspiration to a low level. Except for some vegetables susceptible to cooling damage, the breathing of most vegetables is reduced at a low temperature, and perspiration can be prevented in high humidity.
    [003] In recent years, domestic refrigerators are equipped with a dedicated sealed container for the purpose of preserving vegetables, where the vegetables are cooled to an appropriate temperature, and the humidity in the refrigerator is increased in order to keep the perspiration of vegetables under control. Here, a spray device for spraying mist is known as a unit for increasing humidity in the refrigerator.
    [004] Like a refrigerator equipped with such spraying capacity, there is a refrigerator, in which a spraying device humidifies the space in a vegetable compartment in order to keep vegetables transpiration under control by spraying mist with an ultra atomizing device -sonic when the vegetable compartment is at low temperature (for example, see patent literature 1).

    [007] As shown in figure 6, a vegetable compartment 21 is provided at the bottom of a body housing 26 of a refrigerator body 20, and the front opening of the vegetable compartment 21 is designed to be closed by a door. drawer 22, which can be pulled in a way that opens and closes freely. The vegetable compartment 21 is divided from the top compartment of the refrigerator (not shown) by a dividing plate 2. A fixing hanger 23 is attached to the inner surface of the drawer door 22, and a vegetable container 1 that stores food as vegetables it is mounted on the fastening hanger 23. The top opening of the vegetable container 1 is sealed by a lid 3. The inside of the vegetable container 1 is provided with a defrost compartment 4, and the rear surface of the defrost compartment 4 it is equipped with an ultrasonic atomization device 5.
    [008] As shown in figure 7, the ultrasonic atomization device 5 includes a mist diffuser 6, a water storage container 7, a humidity sensor 8, and a hose receiver 9. 0 water storage container water 7 is connected to a defrost water hose 10 via the hose receiver 9. A portion of the defrost water hose 10 is provided with a cleaning filter 11 to clean the defrost water.
    [009] Next, the operation of the refrigerator as configured in this way is described.
    [0010] First, cooling air cooled by a heat exchange cooler (not shown) circulates along the outer surface of the vegetable container 1 and a lid 3 so that the vegetable container 1 is cooled, and thus the food stored in it is cooled. The defrost water generated from the heat exchange cooler when the cooler is in operation is cleaned by the cleaning filter 11 as it passes through the defrost water hose 10, and is supplied to the water storage container 7 of the cooling device. ultrasonic atomization 5.
    [0011] Next, when the humidity in the refrigerator is detected to be 90% or less by the humidity sensor 8, the ultrasonic atomization device 5 begins to humidify the inside of the refrigerator and to control the humidity to an appropriate level to maintain vegetables in vegetable container 1, fresh. On the other hand, when the humidity in the refrigerator is detected to be 90% or more by the humidity sensor 8, the ultrasonic atomization device 5 for excessive humidification.

    [0015] Publication of the Japanese unexamined patent application no. 6-257933 Summary of the invention Technical problem
    [0016] However, in the conventional configuration described above, the start and stop of the atomization device are generally controlled based on the refrigerator humidity detected by the humidity sensor. With this mechanism, the accuracy or responsiveness of detection can cause a problem. In this case, since the humidity in the refrigerator cannot be obtained precisely, there is a problem where a degree of forced humidification could be too much or too little. Particularly, in a refrigerator storage compartment, that is, low temperature space, substantially sealed, an excessive amount of atomization causes rotting of vegetables by water and the like, and condensation forms in the refrigerator. On the other hand, a smaller amount of atomization causes insufficient humidification of the storage compartment, and thus vegetables and the like cannot be kept fresh.
    [0017] The present invention solves the existing problems described above, and it is an objective of the invention to provide a refrigerator capable of maintaining humidity more appropriately and efficiently without depending on a humidity sensor, provided that the refrigerator is equipped with a atomization unit to increase the ability to maintain freshness by spraying mist.

    [0019] In addition, an aspect of the present invention provides a cooler for circulating cold air which is a gas cooled in a cooling compartment, the cooler including: a divided storage compartment with heat insulation; a spray device configured to provide mist to the storage compartment; a damper provided in an air passage to circulate cold air from the cooling compartment to the storage compartment; a control unit configured to control the spray device so that a damper operation and a spray device operation are coordinated; and a delay unit configured to command the control unit to initiate operation of the spraying device after a second period of time has elapsed since the damper has closed.
    [0020] This configuration allows an atomization unit to efficiently spray mist and properly humidify the interior of the storage compartment. Advantageous effects of the invention

    [0029] A first aspect of the invention provides a refrigerator in accordance with an aspect of the present invention, provides a refrigerator for circulating cold air which is a gas cooled in a cooling compartment, the refrigerator including: a divided storage compartment with insulation of heat; a spray device configured to spray mist into the storage compartment; a damper provided in an air passage to circulate cold air from the cooling compartment to the storage compartment; a control unit configured to control the spray device so that a damper operation and a spray device operation are coordinated; and a delay unit configured to command the control unit to stop the operation of the spraying device after the first period of time has elapsed since the opening of the damper.
    [0030] A second aspect of the invention provides a refrigerator for circulating cold air which is a gas cooled in a cooling compartment, the refrigerator including: a divided storage compartment with heat insulation; a spray device configured to provide mist to the storage compartment; a damper provided in an air passage to circulate cold air from the cooling compartment to the storage compartment; a control unit configured to control the spray device so that a damper operation and a spray device operation are coordinated; and a delay unit configured to command the control unit to initiate operation of the spraying device after a second period of time has elapsed since the damper is closed.
    [0031] The atomization unit is controlled according to the opening and closing time of the damper when the cold air flow is changed, the flow of air flow governing occurrences of condensation and drying on the periphery of the atomization unit. Therefore, an atomization operation can be carried out in the most suitable state for atomization, and thus an atomization device that has an efficient mist spray function and an excellent energy-saving feature can be mounted in a refrigerator.
    [0032] A third aspect of the invention further includes a condensation prevention heater configured to dry a periphery of the heating spray device, wherein the control unit is configured to cause the condensation prevention heater to operate for a period predetermined drying time until the closing signal is received when the damper is in a closed state and the spraying device is in operation based on the closed signal and the second signal.
    [0033] Consequently, unnecessary energization of the condensation prevention heater is not performed when the periphery of the atomization unit is already dry due to the subsequent atomization operation, and thus, not only can energy consumption be reduced, but also an increase in temperature in the storage compartment can be reduced.

    [0035] The voltage to be applied can be reduced to a lower level, and thus miniaturization of the atomization device can be obtained.
    [0036] In the following, an embodiment of the present invention is described with reference to the drawings. The invention is not limited by the modality.
    [0037] Mode 1
    [0038] Figure 1 is a vertical section view of a refrigerator in the mode 1 of the present invention; figure 2 is a front front view of a vegetable compartment and the peripheral area of the refrigerator in embodiment 1 of the present invention; figure 3 is a sectional view taken along line A-A of figure 2 of the mode 1 refrigerator of the present invention; figure 4 is a functional block diagram of the mode 1 refrigerator of the present invention; and figure 5 is a graph of operating time of the mode 1 refrigerator of the present invention.
    [0039] In figures 1 to 4, a heat insulation main body 101 of a cooler 100 includes an outer body 102 made mainly of steel sheet, an inner body 103 molded with a resin such as ABS, and foam, for example, foamed heat insulation material such as hard urethane foam, to fill the space between the outer body 102 and the inner body 103. In this way, the main heat insulation body 101 is thermally insulated from the periphery and is divided into a plurality of storage compartments.
    [0040] A configuration is made in such a way that a refrigerator compartment 104 as a second storage compartment is arranged in the upper portion of the main heat insulating body 101; an alteration compartment 105 as a fourth storage compartment, and an ice maker compartment 106 as a fifth storage compartment are arranged side by side below the refrigerator compartment 104; a vegetable compartment 107 as a first storage compartment is arranged below the switchable switch 105 and ice maker compartment 106; and a freezer compartment 108 as a third storage compartment is arranged in the lowest portion.
    [0041] Refrigerator compartment 104 is normally set at a temperature of 1 to 5 ° C, the lower limit of which does not cause freezing due to refrigeration conservation. Vegetable compartment 107 is set at a temperature of 2 to 7 ° C which is equivalent to or slightly higher than the temperature of refrigerator compartment 104. Freezer compartment 108 is set to a temperature in a freezing temperature range , that is, usually in a range of -22 to -15 ° C for freezing conservation. However, to improve the quality of freezing preservation, freezer compartment 108 can be adjusted to a low temperature of -30 to -25 ° C, for example.
    [0042] Switchable compartment 105 can switch the temperature range to a predetermined temperature range between the refrigeration temperature range and the freezing temperature range, in addition to the refrigeration temperature range 1 to 5 ° C, the temperature range temperature for vegetables from 2 to 7 ° C, and the freezing temperature range of -22 to -15 ° C. The switchable compartment 105 is a storage compartment having an independent door, and is installed on the side of the ice maker compartment 106, and the independent door is often a drawer-type door.
    [0043] In the present embodiment, the switchable compartment 105 covers switchable temperature ranges including the refrigeration temperature range and the freezing temperature range. However, the switchable compartment 105 can be a storage compartment for specific switching use for the above mentioned temperature range between the refrigeration temperature range and the freezing temperature range, under the condition that refrigeration is carried out in the storage compartment. refrigerator 104 and vegetable compartment 107, and freezing is carried out in freezer compartment 108. Alternatively, the switchable compartment 105 can be a storage compartment whose temperature range is fixed in the specific temperature range.
    [0044] The ice maker compartment 106 makes ice by an automatic ice maker (not shown) provided in the upper portion of the ice maker compartment 106, using water sent from the water storage tank (not shown) in the compartment refrigerator 104, and stores the ice in the ice storage container (not shown) disposed in the lower portion of the ice maker compartment 106.
    [0045] The top of the main heat insulating body 101 has a step-like recess towards the rear of the refrigerator 100. A machine chamber 101a is formed in the step-like recess that stores a compressor 109, and the components in the high voltage side of the refrigeration cycle, such as a dryer (not shown) to remove water content. That is to say, the machine chamber 101a that stores the compressor 109 is formed by embedding in the rear area of the uppermost portion of the refrigerator compartment 104.
    [0046] The subjects related to the essence of the invention described below in the present embodiment can be applied to a typical conventional refrigerator, in which a machine chamber is provided in the rear area of a storage compartment in the lowest portion of the main insulating body heat 101, and compressor 109 is arranged in the machine chamber. Alternatively, refrigerator 100 may have what is called a medium freezer configuration, in which the positions of part of freezer compartment 108 and vegetable compartment 107 are replaced.
    [0047] Next, the rear side of the vegetable compartment 107 and the freezer compartment 108 are provided with a coating chamber 110 that generates cold air. A rear partition wall 111 is formed between the vegetable compartment 107 and the cooling chamber 110, and / or between the freezer compartment 108 and the cooling chamber 110. The rear side partition wall 111 forms a passage of carrier air to flow cold air into each compartment, and additionally has heat insulation property to thermally insulate each compartment from cold air.
    [0048] A cooler 112 is arranged in the cooling chamber 110, and a cooling fan 113 is arranged in the upper space of the cooler 112. The cooling fan 113 has the function of forcibly circulating the cold air that is cooled by the cooler 112. Specifically, cooling fan 113 is a fan that sends cold air cooled by cooler 112 to refrigerator compartment 104, switchable compartment 105, ice maker compartment 106, vegetable compartment 107, and freezer compartment 108. A heater 114 is disposed in the lower space of the cooler 112. In the case of the present embodiment, the heater 114 is a radiant heater that is made of glass tube, and thaws the frost and ice that adhere to the cooler 112 and its periphery. A drain pan 115 for receiving defrosted water produced at the time of defrosting is disposed in the lower portion of heater 114. A drain tube 116 is connected from the rearmost portion of drain pan 115 to the outside of refrigerator 100. A Evaporation 117 is disposed outside the cooler 100 downstream of the drain tube 116.
    [0049] In the vegetable compartment 107, a lower storage container 119 is placed that is placed on a frame fixed to the drawer door 118 of the vegetable compartment 107, and an upper storage container 120 that is placed in the lower storage container 119. In the vegetable compartment 107, a lid 122 for substantially sealing the upper storage container 120 is arranged with the drawer door 118 closed. In the case of the present embodiment, the lid 122 is supported by a first division 123 and the inner body 103 which are provided above the vegetable compartment 107. The lid 122 is in close contact with the right and left sides and the rear side of the surface top of the upper storage container 120. In addition, lid 122 is substantially in contact with the front side of the upper surface of the upper storage container 120. Additionally, the boundary space between the lower right and left sides of the rear surface of the container upper storage container 120 and lower storage container 119 is reduced by a strip so that moisture in the food storage does not escape, the strip preventing the upper and lower containers from contacting each other when the upper storage container 120 is in use.
    [0050] The space between the cover 122 and the first division 123 serves as an air passage to pass cold air. The air passage allows cold air to flow, cold air being discharged from an outlet orifice 124 to the vegetable compartment 107, the outlet orifice 124 being formed in the rear side partition wall 111. There is also a space provided between the lower storage container 119 and a second room 125 below the lower storage container 119, and the space serves as an air passage for cold air passage. The lower portion of the rear side partition wall 111 arranged on the rear surface side of the vegetable compartment 107 is provided with an inlet hole 126 for the vegetable compartment 107, the inlet 126 serving as a hole for cold air to return for cooler 112, the cold air having cooled the interior of the vegetable compartment 107 and having been subjected to heat exchange.
    [0051] The subjects related to the essence of the invention described below in the present modality can be applied to a typical conventional refrigerator whose door is opened or closed by a frame fixed to the door and a rail provided in the internal body.
    [0052] The rear partition wall 111 is an element that thermally insulates the air passage, the cooling chamber 110 from the vegetable compartment 107. In the case of the present embodiment, the partition wall on the rear side 111 forms the rear wall of the vegetable compartment 107, and includes a heat insulation portion 152 having insulating property, and a surface portion 151 disposed on the surface of the heat insulation portion 152. Surface portion 151 is composed of resin as ABS that is relatively hard and allows treatment of surface design. The heat insulation portion 152 is composed of low thermally conductive resin with low density as a styrofoam to ensure the insulating property.
    [0053] An electrostatic spray device 131 is embedded in the rear partition wall 111, the electrostatic spray device 131 having an atomization unit 139 that electrostatically atomizes the water content. Specifically, a recess portion is provided on the rear partition wall 111 between the vegetable compartment 107 and the cooling chamber 110, and the spray device 131 is installed in the recess. By providing the recess portion in the rear partition wall 111, the space in the recess portion has low insulating property, and thus the temperature in the recess portion becomes lower than in other portions in the vegetable compartment 107 .
    [0054] The wall thickness of the heat insulating portion 152 where a cooling pin 134 of the rear partition wall 111 is disposed is 10 mm or less. Therefore, especially the cooling pin 134 is cooled, and the temperature of it becomes lower than that in the vegetable compartment 107.
    [0055] A condensation prevention heater 155 is embedded in the rear partition wall 111. The condensation prevention heater 155 is located in the vicinity of the recess, that is, where the spray device 131 is embedded, and between the surface portion 151 and heat insulation portion 152.
    [0056] A cover 153 is provided in front of the cooler 112, and at the rear of the vegetable compartment 107, an exhaust air passage 141 of the freezer compartment 108 is provided between the cover 153 and the rear partition wall 111.
    [0057] In the air passage formed at the rear of the heat insulation portion 152, a damper 145 is provided to adjust the amount of cold air circulation that cools each storage compartment.
    [0058] The spray device 131 includes an atomization unit 139, a voltage application unit 133 and a housing 137. The housing 137 is provided with an atomizing orifice 132 and a supply orifice 138 for supplying water content such as moisture to housing 137. Atomization unit 139 includes a counter electrode 136 and an atomization electrode 135. Atomization electrode 135 is attached to cooling pin 134. Cooling pin 134 is composed of a high thermally conductive element such as aluminum or stainless steel. The atomization electrode 135 and the cooling pin 134 are arranged so as to ensure high thermal conduction between them.
    [0059] The cooling pin 134 is fixed to the housing 137 in such a way that a portion of the cooling pin 134 protrudes out of the housing 137. Counter electrode 136 is an electrode in a donut disk shape ( (ring-shaped) on the side of the vegetable compartment 107 with respect to the location of counter electrode 136 which faces atomization electrode 135. Counter electrode 136 is attached to housing 137 in order to be separated from the atomization electrode 135 over a distance. The central geometric axis of the hole in counter electrode 136 is aligned with the central geometric axis of atomization orifice 132, and the tip end of atomization electrode 135 is arranged on the central geometric axis. In the present embodiment, counter electrode 136 is in the form of a flattened donut disk, but it can be in a dome shape with an opening in the center so that the end of the atomization electrode 135, and the surface of the counter electrode 136 facing the end of the atomizing electrode 135 are separated by the same distance. By adopting the aforementioned format for counter electrode 136, the efficiency of the spray mist can be improved.
    [0060] In addition, the spray device 131 includes the voltage application unit 133 to apply a voltage to a connection between the counter electrode 136 and the atomization electrode 135. In the case of the present embodiment, the application unit of voltage 133 is arranged in the vicinity of atomization unit 139. voltage application unit 133 has two electrodes for applying a voltage, whose negative potential side is electrically connected to atomization electrode 135, while whose positive potential side is electrically connected to counter electrode 136. For example, a high negative potential lower than a reference potential, in a range of -10 to -4 kV is applied to atomization electrode 135, while counter electrode 136 is connected to a reference potential GND, and thus a high voltage is applied to counter electrode 136.
    [0061] The voltage application unit 133 is configured to acquire an SI signal from a delay unit 156 in a control unit 146 of the chiller 100, and be able to adjust the high voltage ON / OFF. The operation of the electrostatic spraying device 131 is controlled by switching ON / OFF the voltage application unit 133.
    [0062] Control unit 146 acquires an S2 signal from an internal temperature sensing unit 150, and an S3 signal from damper 145 to control start / stop of spray device 131, signal S2 to detect a temperature inside the refrigerator compartment 104 which is the second storage compartment of the refrigerator 100, and the signal S3 to adjust a cooling amount and an air flow. The control unit 146 also controls start / stop of the condensation prevention heater 155 for drying the atomization electrode 135. A signal S4 is used for the control.
    [0063] Next, the operation and effect of the refrigerator as configured in this way are described.
    [0064] First, the operation of a refrigeration cycle is described. The refrigeration cycle begins to operate and a cooling operation is performed based on a signal from a control substrate (not shown) according to a temperature setting on the refrigerator. The high temperature, high pressure refrigerant discharged by the operation of compressor 109 is condensed and liquefied to some degree by a condenser (not shown), and is additionally condensed and liquefied as it flows through a refrigerant pipe (not shown) arranged on the surfaces sides or rear surface of the refrigerator 100, or the front facade of the refrigerator 100, and prevents condensation of the refrigerator 100, and finally reaches a capillary tube (not shown). Subsequently, in the capillary tube, the refrigerant is decompressed while exchanging heat with a suction tube (not shown) for compressor 109, and becomes low pressure, low temperature liquid refrigerant and reaches the cooler 112.
    [0065] The low pressure, low temperature liquid refrigerant exchanges heat with the air in each storage compartment as the air in the discharge air passage 141 of the freezer compartment 108, the air being transported by the operation of the cooling fan 113, and thereby the refrigerant in the cooler 112 is vaporized. At that point, cold air to cool each storage compartment in the cooling chamber 110 is generated.
    [0066] The cold low temperature air generated in the cooling chamber 110 is sent to the refrigerator compartment 104, the switchable compartment 105, the ice maker compartment 106, the vegetable compartment 107, and the freezer compartment 108 by the fan cooling unit 113.
    [0067] Cold air is derived using the air passage structure and damper 145, and is sent to each compartment in order to maintain the desired temperature range of the compartment.
    [0068] The amount of cooling air for cooler compartment 104 is adjusted by damper 145 based on a temperature sensor (not shown) provided in cooler compartment 104, and thus cooler compartment 104 is cooled to a desired temperature. In particular, the vegetable compartment 107 is set at a temperature of 2 to 7 ° C by a cold air distribution ON / OFF operation and / or a heating unit (not shown).
    [0069] In the vegetable compartment 107, an outlet port 124 is arranged for the vegetable compartment 107, which discharges cold air, and an inlet hole 126 that draws cold air into the vegetable compartment 107. The outlet port 124 it is an orifice for discharging cold air that has cooled cooler compartment 104 and is arranged in the path of a return air passage to cooler compartment 140 to return cool air to cooler 112. Inlet 126 is an orifice to suck in the cold air that was discharged into the vegetable compartment 107, and flowed along the outer periphery of the upper storage container 120 and lower storage container 119, and cooled the inside of the upper storage container 120 and lower storage container 119 in an indirect way. The cold air sucked through the inlet port 126 into the vegetable compartment 107 is returned to the cooler 112.
    [0070] The air passage and the cooling chamber 110 exist behind the rear partition wall 111 which is opposite side by side where the spray device 131 is attached, and the cooling pin 134 of the spray device 131 which it is closest to the air passage and cooling chamber 110 is heavily cooled by the cold air that is generated in the cooler 112 by the operation of the cooling system. Specifically, the cold air that was cooled by the cooler 112 and reached the vicinity of the cooling fan 113 has a temperature of approximately 25 to -15 ° C. The cold air that passes through the air passage cools the cooling pin 134 to a temperature of approximately -10 to 0 ° C by conduction of heat in a thin portion of the heat insulation portion 152. At that point, like the cooling 134 is a high thermally conductive element, the cooling pin 134 tends to transfer low heat, and also as the cooling pin 134 and the atomization electrode 135 are connected together in a highly conductive state, the atomization electrode 135 is also cooled to a temperature of approximately -10 to 0 ° C.
    [0071] Vegetable compartment 107 is cooled so that its temperature is maintained in a range of 2 to 7 ° C. And the vegetable compartment 107 is in a relatively high humidity condition due to the perspiration of the vegetables and the like. Consequently, the atomization electrode 135 which is cooled through the cooling pin 134 has a temperature below the dew point temperature, and in this way water is generated and adheres to the atomization electrode 135 including the tip end of which is the spray tip tip.
    [0072] The voltage application unit 133 applies a high voltage through the atomization electrode 135 and the counter electrode 136 (for example, the atomization electrode 135 in -10 to -4 kV, the counter electrode 136 in GND ), the atomization electrode 135 to which drops of water adhere being the negative voltage side, and the counter electrode 136 being the positive voltage side, and thereby the operation of the spraying device 131 begins.
    [0073] At this point, a corona discharge occurs between the atomization electrode 135 and counter electrode 136, and the water droplets (in the present embodiment, the water droplets are the water content in the air that condenses) adhering to the end spray tip of atomization electrode 135 is charged and transformed into tiny particles by electrostatic energy. In addition, as the water droplets are electrically charged, the water droplets become invisible microscopic haze with a tiny electrical charge of the order of several nm due to Rayleigh fission. The microscopic mist contains ozone, OH radicals, oxygen radicals that are assumed to be generated by the aforementioned corona discharge.
    [0074] Although the difference in voltages applied to the electrodes is an externally high voltage of 4 to 10 kV, the discharge current value at that time is in the order of several | LLA, and the input is an extremely low value of 0.5 at 1.5W, and thus adequate spraying is carried out.
    [0075] In this way, the microscopic mist of the nanometer order that is generated on the atomization electrode 135 is sprayed out from the atomization unit 139. At that moment, an ion wind is generated and the air in the housing 137 flows to outside the atomization unit 139. At that time, the inner side of the housing 137 has negative pressure, and thereby additional highly moist air flows into the atomization unit 139 through the supply orifice that is supplied on the housing side 137. repeat this cycle, the spray device 131 can spray mist continuously.
    [0076] In addition, the microscopic mist generated reaches the inside of the lower storage container 119 with the ion wind. Since the mist contains extremely small particles, the mist diffuses easily, and thus the microscopic mist also reaches the upper storage container 120. The sprayed mist is generated by a high pressure discharge, and thus has a negative electrical charge.
    [0077] In the vegetable compartment 107, especially leaves of green vegetables, fruits, and similar vegetables and fruits are preserved, and these vegetables and fruits tend to wilt due to their perspiration or perspiration while being preserved. Vegetables and fruits that are preserved in the vegetable compartment 107 normally include those vegetables and fruits that have withered in some way due to perspiration on the way home after being acquired or perspiration while being preserved, and thus have a positive electrical charge. In this way, negatively charged mist tends to collect on the surfaces of vegetables, and therefore the freshness of the vegetables is increased.
    [0078] In addition, the microscopic mist of the nanometer order that was sprayed from the spraying device 131 and adhered to the surfaces of the vegetables has ozone in addition to a negative electrical charge due to a large number of OH radicals contained in the fog. Consequently, the mist sprayed from the spray device 131 has antibacterial properties, disinfecting properties, and the like, and thereby freshness of the vegetables conserved in the storage compartment can be further increased. Additionally, due to the negatively charged mist adhering to the surfaces of vegetables, toxic substances such as agricultural chemicals adhering to the surfaces of vegetables can come off or can be captured by the mist, and thus can be easily removed. In addition, an effect of removing agricultural chemicals due to oxidative decomposition can be obtained. Additionally, by applying a mist stimulus to vegetables, the antioxidant action occurs, and an effect of an increase in nutrients as the amount of vitamin C is promoted.
    [0079] Cooler compartment 104 is controlled to be in a desired temperature range by damper 145 as described above. That is to say, when the refrigerator compartment 104 has a higher temperature than the desired temperature, the refrigerator compartment 104 is cooled by opening the damper 145 to introduce cooler air. When the buffer 145 is opened, relatively dry air that has cooled the refrigerator compartment 104 flows into the vegetable compartment 107 through the outlet port 124, and thereby the vegetable compartment 107 is cooled. Thus, in the refrigerator 100 in the present embodiment, cold air does not flow directly into the vegetable compartment 107, and damper 145 does not control cold air either. That is to say, the vegetable compartment 107 is arranged in the path of the return air passage to the refrigerator compartment 140, along which the cold air flowing out of the refrigerator compartment 104 returns to the cooling chamber 110.
    [0080] In the case where the environment in the vegetable compartment 107 has a high humidity, it can be considered that the atomization electrode 135 has excessively condensed water. In that case, by using the return air from the relatively dry refrigerator compartment 104 controlled by the damper 145, the excessively condensed water droplets on the atomization electrode 135 are dried, and an appropriate amount of condensed water is formed, and thus atomization electrode 135 is controlled to be in a feasible atomization state.
    [0081] In general, compared to the cold air in the refrigerator compartment 104, the cold air in the vegetable compartment 107 has high humidity, and the cold air flowing in from the refrigerator compartment 104 is relatively dry air in the vegetable compartment 107, and thereby cold air flowing in from the refrigerator compartment 104 is used to dry the atomization electrode 135 in the present embodiment.
    [0082] That is to say, the air flow, the ambient temperature, and the dry state in the vegetable compartment 107 vary according to the opening and closing of the damper 145 of the refrigerator compartment 104 located upstream of the vegetable compartment 107 in the air passage of cold air. Therefore, it can be assumed that opening and closing damper 145 that is provided upstream of vegetable compartment 107 in the air passage causes the cold air flow to change the cold air flow governing condensation and drying at the periphery of the atomization unit 139 among the typical environmental changes of the refrigerator 100 storage compartment. Thus, the opening and closing of the damper 145 are essential factors that have an influence on the periphery of the atomization unit 139, that is, condensation and drying on the electrode. atomization spray 135.
    [0083] However, drying by cold air at the time of opening of the shock absorber 145 may not be able to sufficiently dry the excessively condensed water content of the atomization electrode 135, and thus the condensation prevention heater 155 is energized regularly, and the atomization electrode 135 is regularly dried by means of force. Therefore, the impracticality of atomization due to excessive condensation of the atomization electrode 135 can be avoided.
    [0084] Thus, the opening and closing operations of the buffer 145 of the refrigerator compartment 104 located upstream of the vegetable compartment 107 is an essential time that makes it possible to predict that the environment on the periphery of the vegetable compartment 107 and atomization unit 139 changes, in particular, the flow of cold air at the periphery of the atomization unit 139 changes. However, the opening and closing time of the buffer 145 does not immediately cause the moisture in a periphery of the atomization unit 139 in the vegetable compartment 107 to change, and the humidity changes with a delay of time. Consequently, ON / OFF the high voltage is controlled by the voltage application unit 133 with a prescribed time delay interval from the open / close signal of the damper 145, the delay being made by the delay unit 156 and thereby fog is sprayed efficiently over a moisture range of a workable atomization region.
    [0085] In the present embodiment, a configuration has been described, in which the spray device 131 is attached to the rear partition wall 111, however, since the cooling pin 134 can be cooled, the spray device 131 can be attached to the first partition wall 123 so that mist can be sprayed from the top surface of the vegetable compartment 107. In that case, the spraying device 131 can be easily installed in a structural sense by changing the shape of the cooling pin 134 from a rod-like shape to a plate-like shape, and tuning the spray device 131.
    [0086] In the following, the control content in the specific spraying device 131 is described using the operating time graph of figure 5.
    [0087] First, in the operational state of the refrigerator 100 at the time of point A of figure 5, the internal temperature detection unit 150 detects the temperature in the refrigerator compartment 104 which is the second storage compartment, and a detection result enters in control unit 146, the result of the detection being an S2 signal. At that point, the control unit 146 acquires a "closed state" signal from buffer 145, and determines that the internal temperature is not raised based on signal S2, and keeps buffer 145 in a closed state. That is to say, the refrigerator compartment 104 is not cooled. As the damper 145 is closed, dry cold air does not flow into the vegetable compartment 107, and thus the interior of the vegetable compartment 107 has high humidity. The moisture on the periphery of the atomization unit 139 is also in the workable atomization region (shaded area (dashed area) in figure 5) in which the spray device 131 can atomize. In this way, the voltage application unit 133 adjusts the high voltage ON, and adjusts the spray device 131 in an operating state so that the spray device 131 sprays microscopic mist from the atomization electrode 135 into the compartment of vegetables 107. During the spraying time, the condensation prevention heater 155 is in a stopped state, and is considered to be a normal atomization / condensation period of the atomization electrode 135.
    [0088] Next, at the time of point B, the control unit 146 determines that the temperature in the refrigerator compartment 104 has become high, based on the signal S2, and generates an open signal, and sets the damper 145 in a state open, and maintains the state.
    [0089] Therefore, cold air flows into the cooler compartment 104 to cool the cooler compartment 104, while the open state signal (included in signal S3) from the buffer 145 is inserted into the control unit 146, and the open signal is inserted into the delay unit 156.
    [0090] In this way, as the damper 145 is open, the cold dry air flows into the vegetable compartment 107, and thus the humidity in the vegetable compartment 107 begins to decrease. However, the humidity in a periphery of the atomization unit 139 does not decrease immediately, and the operation of the spraying device 131 continues for the determined time because the current humidity is in the feasible atomization region.
    [0091] At the time of point C after the specified time has passed, the buffer 145 is in an open state, and thus the humidity in the vegetable compartment 107 and in a periphery of the atomization unit 139 still decreases, and deviates from the workable region atomization. In that time, the delay unit 156 begins to count the time elapsed from the moment (point B) when an open signal from damper 145 is generated, and transmits a first signal (included in signal Sl) to control the operation of the spraying device 131 when a predetermined first period of time TI passes. When the spray device 131 acquires the first signal, the high voltage is set to OFF by the voltage application unit 133, and the spray device 131 for operation. For previously defining the time determined for the first time period TI between the time (point B) when the state of the buffer 145 is changed from "close" to "open", and the time (point C) when the spraying device 131 is stopped, atomization control can be performed without using a complicated moisture measurement method. For the value of TI in this case, 10 to 15 minutes is preferable, but TI can be experimentally determined freely according to the cooling performance of the refrigerator actually used 100.
    [0092] Then, at the time of point D, the control unit 146 determines that the temperature in the refrigerator compartment 104 has become low, based on a result of detection by the internal temperature detection unit 150, and generates a signal to close, and sets buffer 145 in a closed state, and maintains the state. Therefore, the refrigerator compartment 104 is not cooled, while the closed status signal (included in signal S3) from the buffer 145 is inserted in the control unit 146, and the closing signal is inserted in the delay unit 156.
    [0093] In this way, as the damper 145 is closed, no dry cold air flows into the vegetable compartment 107, and thus the humidity in the vegetable compartment 107 begins to increase. However, the humidity in a periphery of the atomization unit 139 does not increase immediately, and the operation of the spraying device 131 remains stopped for the predetermined time because the current humidity is outside the feasible atomization region.
    [0094] Then, at the time of point E after the determined time has passed, the buffer 145 is in a closed state, and thus the humidity in the vegetable compartment 107 and in a periphery of the atomization unit 139 still increases, and enters in the feasible atomization region. Thus, in that time, the delay unit 156 begins to count the elapsed time from the moment when the closing signal is generated, and transmits a second signal (included in the signal S1) to control the operation of the spraying device 131 when a second predetermined period of time T2 passes. When the spray device 131 acquires the second signal, the high voltage is set to ON by the voltage application unit 133, and the spray device 131 is set in operation. For previously defining the time determined for the second time period T2 between the time (point D) when the state of the buffer 145 is changed from "open" to "close", and the time (point E) when the spraying device 131 is started, atomization control can be performed without using a complicated moisture measurement method in a similar way as in the case of the first T2 time period. For the value of T2 in this case, 5 to 10 minutes is preferable, but T2 can be experimentally determined freely according to the cooling performance of the refrigerator actually used 100.
    [0095] Then in the condensation / atomization period between the time of point F and the time of point G, the operation described above between point B and point E is repeated for two cycles, and efficient mist spraying continues.
    [0096] Next, at the time of point H, when the buffer 145 is in a closed state and the spraying device 131 is in operation, the moisture in a periphery of the atomization unit 139 is also in a workable atomization region, the atmosphere and the like of a periphery of the atomization unit 139 is heated by operating the condensation prevention heater 155. A drying time period T3 during which the condensation prevention heater 155 is operated is set between the current time and the point I time when the buffer 145 is in an open state the next time. Therefore, even when the atomizing electrode 135 is in a state of excessive condensation, the atomizing electrode 135 can be completely dry, and in this way mist can be gently sprayed subsequently. For the value of T3 in this case, approximately 10 minutes is preferable, but T3 can be experimentally determined freely according to the thermally conductive performance of the refrigerator actually used 100. Thus, the drying time period of the atomization electrode 135 is periodically provided.
    [0097] The delay unit 156 desirably establishes that the first period (Tl)> the second period (T2). This is because, in a high humidity storage compartment such as the vegetable compartment 107, the rate of decrease in the unit after buffer 145 is opened is greater than the rate of increase in humidity after buffer 145 is closed. In other words, the decrease in humidity rate in the first period is slow, and so even when a longer first period of time is adjusted, spraying and a high humidity state can be achieved, while the increase in humidity rate in the second period it is fast, and thus even when a second shorter period of time is adjusted, spraying in a high humidity state can be carried out.
    [0098] Thus, by adjusting the first period of time to be equal to or greater than the second period of time, spraying in a high humidity state can be performed, and thus the spraying rate of the spraying device 131 can be improved, which performs spraying in the peripheral air using condensed water.
    [0099] In addition, in the present embodiment, when mist is sprayed in a refrigerator storage compartment, the mist spray rate of the spray device 131 is preferably 50% or more and 80% or less. This is because, in a state of high humidity and low temperature like the state of a refrigerator, when a large amount of fog is sprayed, fog on the surface of the wall is condensed, and thus a small amount of fog is preferably sprayed by a long time. Therefore, to obtain a sufficiently continuous effect with a small amount of mist, a spray rate of 50% or more is required.
    [00100] In the present embodiment, to provide a small amount of mist stably, a period of drying time for atomization electrode 135 is periodically provided. By adjusting the spray rate to 80% or less for operating states including a state in which the spraying device is in operation, however spraying is not performed due to a dry state, excessive condensation of the atomization electrode 135 is suppressed, and thereby safe and stable mist spraying can be obtained.
    [00101] In the present embodiment, during a drying time T3, even in the switching time between periods of dry time and condensation, the spraying device 131 is put into operation to efficiently spray mist, meanwhile, the spraying device 131 can be stopped to improve energy-saving performance.
    [00102] In the present embodiment, it has been described that the time to energize the condensation prevention heater 155 is once for every three cycles of the damper 145 open and close operations. However, provided that the atomization electrode 135 is completely dry , the energization time can be once for an arbitrary number of cycles.
    [00103] As described above, the refrigerator in the present embodiment includes: the vegetable compartment 107 which is a thermally insulated storage compartment; atomization unit 139 for spraying mist in the vegetable compartment 107; the damper 145 arranged upstream of the vegetable compartment 107 in the air passage; the condensation prevention heater 155 for drying a periphery of the atomization unit 139; and the control unit 146 for controlling the operation of the atomization unit 139 using the open / close signals of the damper 145 as an input. By the control unit 146 having the delay unit 156 which controls the atomization unit 139 by delaying an atomization operation for a certain time with respect to the open / close signals of the damper 145, the mist spraying operation is carried out in a state appropriate moisture content of atomization unit 139, which is in the workable atomization region. In this way, efficient and appropriate atomization can be obtained, and fresh vegetable quality can be further improved.
    [00104] In this case, when the state of the shock absorber 145 is changed from "open" to "closed", the spraying device 131 is adjusted in operation after a certain time has elapsed, while when the state of the shock absorber 145 is changed from "closed" "to" open ", the spraying device 131 is stopped after a specified time has elapsed.
    [00105] As described above, in the present modality, for the open / close signals of damper 145, that is, both for the open signal and the closed signal, by delaying an atomization operation for a determined time, the spray 131 can be operated more efficiently in the effective operation of refrigerator 100, efficient mist spraying can be achieved.
    [00106] In this way, the appropriate atomization is obtained efficiently, and not only is the quality of the refrigerator 100 provided with the spraying device 131 improved, but also the amount of energy required to control the spraying device 131 can be reduced to a level low.
    [00107] When the time to energize the condensation prevention heater 155 is once for a plurality of cycles of the open and close operations of the damper 145, the number of times to energize the condensation prevention heater 155 is reduced, and in this way not only can energy consumption be further reduced, but also an increase in temperature in the vegetable compartment 107 is suppressed, thereby allowing preservation of high quality food.
    [00108] The atomizer head 139 includes an electrostatic atomization system having atomization electrode 135 and counter electrode 136, atomization electrode 135 being connected to a negative potential lower than a reference potential, and the contra -136 electrode being connected to the GND reference potential. By applying a high voltage through the voltage application unit 133, microscopic mist of the order of nanometer, having negatively charged OH radicals is sprayed more efficiently than in the case where the atomization electrode 135 is connected to the positive side instead of the reference potential GND. Therefore, an input energy for the voltage application unit 133 can be small, and thus miniaturization of the spray device 131 can be obtained, and mist spraying can be performed in less space.
    [00109] In the present embodiment, the storage compartment for spraying mist in the refrigerator 100 is the vegetable compartment 107, however it can be a storage compartment in another temperature range such as the refrigerator compartment 104 or the switchable compartment 105. In this case , several applications can be developed.
    [00110] In the present modality, heat conduction from the air passage through which cold air flows is used for a cooling unit to cool each storage compartment formed of the cooler 112, meanwhile, a cooling unit using a Peltier element can also be considered. Industrial applicability
    [00111] As described above, the refrigerator according to one aspect of the present invention can obtain appropriate atomization in a storage compartment, and thus can be applied not only to a domestic or industrial refrigerator, or a refrigerator exclusively for vegetables, but also distribution of low temperature food such as vegetables or storage.
