Cooling device for side-by-side refrigerators {APPARATUS FOR COOLING AIR SUPPLY IN SIDE-BY-SIDE TYPE REFRIGERATION}
[11] The present invention relates to a cold air supply structure of a side-by-side refrigerator, in detail, to balance the amount of cold air discharged through the cold air outlet formed on the left and right sides of the refrigerating chamber and to enable centralized cooling of a specific portion as necessary. It relates to a cold air supply unit.
[12] In general, the side-by-side type refrigerator has a relatively large capacity and is equipped with various functions, and the freezer compartment and the refrigerating compartment are installed at the left and right sides of the refrigerator such that the freezer compartment and the refrigerating compartment are vertically vertically respectively, and a cooler chamber having an evaporator mounted on the rear side of the freezer compartment. It is provided to suck the air in the freezer compartment and the refrigerating chamber to the lower side and discharged to the upper side at the same time to be configured to perform the refrigerating and freezing functions respectively by circulating into each chamber.
[13] These side-by-side refrigerators are configured to be selectively moved up and down in the shelves for storing foods, etc., respectively in the refrigerator, and among them, a separate food container may be stored in a lower part of the upper shelf. Some food containers are also provided.
[14] In particular, in the case of vegetables, in order to maintain their freshness, in addition to refrigeration, moisturization is required, so it is common to store vegetables by installing a separate vegetable storage box at the bottom of the refrigerator compartment.
[15] 1 is a longitudinal sectional view showing a cold air supply structure of a conventional side-by-side refrigerator.
[16] As shown in the drawing, the cold air supply structure of the conventional side-by-side refrigerator is formed in parallel to each other and separated by the trimming section 6, respectively, of the freezing compartment F and the refrigerating compartment R, and the freezing compartment F. The cooler chamber 1 which is separated and formed so as to form a space separate from the freezing chamber F at the rear, and the evaporator 2 and the blower fan 3 are installed, and the cold air generated in the cooler chamber 1 is the refrigerating chamber R. The supply passage 4 formed on the upper side of the trimming section 6 so as to be supplied to the cooling section and a passage through which cold air, which has risen in temperature in the refrigerating chamber R, returns to the cooler chamber 1, is located at the lower side of the cutting section 6. And a damper (8) for adjusting the amount of cold air supplied and provided on the refrigerating chamber side of the supply passage (4).
[17] The cold air generated by the evaporator 2 is supplied to the freezing chamber F and the refrigerating chamber R by the blower fan 3, and the cold air that has risen in temperature by heat exchange with the stored foods stored in each chamber is evaporated again. The inside of the refrigerator is cooled while repeating the circulation returned to the side.
[18] In addition, the inside of the refrigerating chamber is provided with a plurality of shelves 12 for storing stored foods, etc., a lower vegetable storage box 13 for storing vegetables is generally installed below.
[19] On the other hand, in the case of a general refrigerator in which the freezer compartment is located at the upper part of the refrigerating compartment, since the cold air whose temperature has risen in the refrigerating compartment is taken back to the evaporator located at the back of the freezer compartment as the upper part of the refrigerating compartment, it is quite suitable for the configuration of the cold air discharge port and the suction port. In the case of side-by-side refrigerators, the cold air that has risen in the refrigerating compartment only needs to be returned through the cold air inlet formed at any position on the side of the refrigerating compartment, so that the positions of the cold air outlet and the inlet can be freely configured. Has an advantage.
[20] Therefore, it is proposed that a plurality of cold air discharge ports are formed inside the refrigerating chamber R for even cooling of the entire interior thereof, and the rear discharge port 9, the upper discharge port 10, and the side surface as shown in FIG. Discharge port 11 and the like.
[21] However, such a plurality of cold air outlets are only meaningful in that they can supply cold air evenly to the inside of the refrigerating chamber, and in reality, when the temperature distribution in the refrigerating chamber is temporarily imbalanced, such an unbalanced state can be more efficiently within a short time. In order to solve the problem, there is a need for an apparatus capable of controlling the discharge of cold air through the plurality of cold air discharge ports.
[22] The present invention is to provide a cold air supply device of the side-by-side type refrigerator that can efficiently control the amount of cold air discharged from the discharge port formed in the inner left and right sides of the refrigerating chamber in response to the necessity arises as described above.

[24] In addition, a left temperature sensor and a right temperature sensor are additionally provided on the inner left side and the right side of the refrigerating chamber, respectively, and the controller is configured to recognize a detection signal of the temperature sensor and transmit a driving signal to the opening and closing means. When the left and right temperature sensors sense the same temperature, both the left and right branch flow paths are opened, and when the temperature of either one of the left and right temperature sensors is high, only the branch flow path of the high temperature side is detected. It is preferable to open selectively.
[25] Furthermore, the opening and closing means includes a motor for driving forward rotation or reverse rotation under the control of the controller; A damper rotatably mounted by the motor; It is preferable to comprise.
[26] Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.
[27] Figures 2 to 4 show the structure of one embodiment of the present invention, Figure 2 is a front sectional view, Figure 3 is a front view showing the mounting position of the temperature sensor as the door of the refrigerating chamber is opened, Figure 4 2 is an enlarged view of a main part of FIG. 2.
[28] As shown, the cold air supply apparatus according to the present invention includes a supply passage (4) for supplying cold air from the cooler chamber (1) to the refrigerating chamber (R); A connection channel 20 connected to the supply channel 4 and connected to the left and right discharge ports 11a and 11b of the refrigerating chamber R; A left branch passage 21 branched from the connection passage 20 and connected to the left discharge port 11a of the refrigerating chamber R; A right branch passage 22 branched from the connection passage 20 and connected to the right discharge port 11b of the refrigerating chamber R; Opening and closing means (30) provided at branch points of the left and right branch passages (11a, 11b) to selectively open and close the left and right branch passages (11a, 11b); A control unit (not shown) for controlling the opening and closing of the opening and closing means 30; It is configured to include.
[29] Here, when the opening and closing means 30 is placed in the neutral position, the cold air supplied through the connection flow path 20 is equally supplied to the left and right branch flow paths 11a and 11b, and when one side is closed, only the opposite branch flow path is provided. Cold air will be supplied.
