    FIELD OF THE INVENTION
    The present invention relates to a food preparation apparatus. In particular, the present invention relates to a food preparation apparatus by means of the movement of a flow of hot air over the food products to heat them. BACKGROUND OF THE INVENTION
    A food preparation apparatus is known by means of EP 2,034,872 B1. The appliance is generally used in a domestic environment and provides a means of preparing food by circulating a flow of hot air around the food products to heat and / or cook the food. This apparatus generally comprises a shelter with a closed food preparation chamber, in which food products are placed and a flow of hot air is then circulated around the food preparation chamber to heat the food by a fan which is driven by an engine.
    During the heating process, steam is generated by the water contained in the food, which causes increased pressure in the food preparation chamber. In addition, other liquids, such as oil, are also discharged from the food. Therefore, hot air ventilation is provided through the shelter, so that air, steam and oil under higher pressure in the food preparation chamber are expelled through the hot air ventilation of the food preparation chamber outside the food preparation chamber. device.
    A disadvantage of a conventional food preparation apparatus, however, is the fact that the hot air in the food preparation chamber is known to heat the housing of the apparatus. This can cause damage or discomfort when a user contacts the shelter. In addition, it is also necessary to cool internal components, such as a motor to drive the fan, to prevent the components from overheating and having reliability problems.
    An attempt to overcome the above problems is the provision of a cooling air duct in the shelter and a cooling air fan to force the flow of fresh air into the shelter, to force excessive heat out of the appliance and to prevent overheating. the outer surface of the shelter and internal components. This cooling air channel generally has an inlet at the top end of the shelter and an outlet at the bottom end of the shelter, so that the cooling air is forced to flow through the inlet, along the cooling air channel and the outlet. .
    A problem with the provision of a cooling air and channel fan, however, is the need for additional components, which increases the cost of the device and reduces its reliability. In addition, the fan increases the noise of the device during use. SUMMARY OF THE INVENTION
    It is, therefore, an object of the present invention to provide a food preparation apparatus that substantially alleviates or overcomes the problems mentioned above.
    According to the present invention, a food preparation apparatus is provided which comprises a shelter, a food preparation chamber in the shelter which has an internal wall that defines a space for receiving food with an air inlet opening and an air opening. air discharge, a fan to move hot air flow successively through the air intake opening, the food receiving space and the air discharge opening, and an air guidance passage to return the air flow from the air conditioner. air discharge towards the air intake opening separate from the food receiving space, where the shelter comprises a cooling air channel and a hot air vent to exhaust the hot air flow from the food preparation chamber to the outside of the shelter with a restricted section that has a reduced cross-sectional area, in order to generate Venturi effect in the ventilation of hot air, in which an outlet to the d and cooling air communicates with the hot air ventilation in the restricted section, so that a low pressure region is formed at the outlet and a flow of cooling air is deposited along the cooling air channel and for ventilation of hot air.
    Advantageously, the hot air ventilation comprises an opening for the food preparation chamber and the cross-sectional area of the hot air ventilation is reduced from the opening for the restricted section.
    Conveniently, the hot air vent comprises an outlet on an opposite side of the restricted section to the opening that communicates with the outside of the shelter.
    The cross-sectional area of the hot air vent may increase from the restricted section to the outlet.
    In one embodiment, the hot air vent comprises a wall that converges inwardly to the hot air vent to form the restricted section.
    In another embodiment, the wall converges to an opposite wall, to form the restricted section.
    Conveniently, the wall and the opposite wall converge to form the restricted section.
    Advantageously, the wall is an upper or lower wall and the opposite wall is the opposite upper or lower wall.
    In another embodiment, the wall is arched and at least one section of the wall converges towards a diametrically opposite section of the wall.
    The cooling air channel can comprise a spaced entrance to the outlet that communicates with the outside of the shelter, so that the cooling air is deposited in the cooling air channel when the cooling air is deposited along the air channel. cooling air and for hot air ventilation.
    The entrance can be formed on a base of the shelter.
    The apparatus may additionally comprise a component chamber, in which the cooling air channel communicates fluidly with the component chamber, in such a way that the cooling air is deposited through the component chamber.
    Advantageously, the hot air outlet comprises a series of hot air channels that communicate between the food preparation chamber and the outside of the shelter, each channel comprising a restricted section.
    The apparatus may comprise a series of cooling air channels.
    A part of the food preparation chamber can be removable on the front side of the appliance, such that the food products are removable from the food receiving space and the hot air ventilation can be formed on the rear side of the appliance opposite front side.
    In view of the above, cooling air can be deposited through the cooling air channel and exhaust the shelter without the need for an additional fan or other components to create a flow. The reliability of the cooling system, therefore, increases with respect to the conventional appliance, due to the absence of components or moving parts in the cooling system.
    In addition, the noise level generated by the device is minimized.
    In addition, the air flowing through the component chamber can conduct heat away from the components disposed therein and, thus, the reliability of the components will be greater.
    The combined airflow that has been exhausted from the hot air vent outlet will be at a lower temperature than that of the hot air and other fluids expelled from the food preparation chamber and, therefore, the likelihood of damage or injury caused by the fluid that exhaustion through hot air ventilation is minimized. In addition, the speed of the combined air flowing from the shelter is minimized.
    An advantage of the ventilation and fan that are positioned at the top of the food preparation chamber is to prevent liquid discharged from food products from being collected over the fan and discharged through ventilation. BRIEF DESCRIPTION OF THE FIGURES
    Preferred embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
    Figure 1 shows a schematic cross-sectional view of a food preparation apparatus. DETAILED DESCRIPTION OF ACHIEVEMENTS
    A food preparation apparatus is shown in Figure 1 comprising a shelter 1 and a food preparation chamber 4 formed in the shelter 1. The apparatus is configured to prepare food products placed inside by means of heating, in order to heat and / or cooking ready-to-eat food products.
    The shelter 1 has an outer surface 2 and an inner surface 3 that defines a wall of the food preparation chamber 4. An internal wall 5 is arranged in the food preparation chamber 4 and defines a food receiving space 6 in which food products to be heated and / or cooked (not shown). The inner surface 3 of the shelter 1 and the inner wall 5 extend substantially parallel, but spaced apart to define an air orientation passage 7 between them, along which hot air is circulated in the food preparation chamber 4, as will be explained later.
    The inner wall 5 comprises a lower part 8 and a side wall 9 which extends around the lower part 8 and vertically from it. The lower part 8 of the inner wall 5 is equipped with an air-permeable section 10 which acts as a hot air inlet opening for the food receiving space 6 and an upper part 12 of the inner wall 5 is equipped with a discharge opening. of hot air 13 to allow air to flow through it for the air guidance passage 7. In the present embodiment, the air-permeable section 10 extends across the entire lower portion 8, although it may extend over only a part of the lower part 8. The air-permeable section 10 is formed by known means, such as a screen or grid arrangement.
    A fan 14 is arranged in the food preparation chamber 4, above the discharge opening 13 of the inner wall 5. The fan 14 is coupled to an electric motor 15 that acts as a means of steering to rotate the fan 14. The fan 14 is operable to move a flow of hot air by means of air suction through the discharge opening 13 by means of low pressure generated on one side of the fan 14, expelling air flow under high pressure to the air guidance passage 7 defined between the inner surface 3 of the shelter 1 and the inner wall 5. The air expelled by the fan 14 therefore flows along the air guidance passage 7, which acts as an air guidance medium for the air permeable section 10 of the wall internal 5. The air then flows through the air-permeable section 10 to the food receiving space 6.
    A heater 16 that acts as a radiant heat medium is disposed in an upper part 17 of the food preparation chamber 4. In this embodiment, the heater 16 is disposed in an upper part of the food receiving space 6 below the discharge opening 13 , although it is appreciated that the heater 16 can be arranged above the inner wall 5. The heater 16 is arranged to heat the air flowing through the upper part of the food receiving space 6. In addition, the heater 17 is positioned in the space receiving food 6 to radiate heat to the heat receiving space 6 and towards any food product disposed there.
    The air flowing in the air guide passage 7 between the lower part 8 of the inner wall 5 and a base 18 of the inner housing surface 3 is directed to flow upwards through the air-permeable section 10 of the inner wall 5 by means of an air deflector 19 seated on the base 18 of the inner housing surface 3 and directs the air flow upwards.
    A hot air vent 20 is formed in the shelter 1 and extends between the inner surface 3 and the outer surface 2 to define a hot air outlet from the food preparation chamber 3 to the outside of the appliance. The vent 20 is arranged at the top 17 of the food preparation chamber 4 near the fan 14. The vent 20 and the fan 14 are positioned at the top of the food preparation chamber 3 to help prevent the liquid discharged from the products food is collected on the fan 14 and discharged through the ventilation 20. In the present embodiment, the fan 14 is a radial fan and the ventilation 20 is formed in the shelter 1 on a line that extends radially to the axis of rotation of the fan 14 It will be appreciated, however, that alternative means of air circulation are conceived in the food preparation chamber 4.
    The vent 20 has an elongated opening 22 that extends along a rear side 23 of the inner surface of the shelter 3 parallel to a base 34 of the shelter 1 and communicates the food preparation chamber 4 with the ventilation 20. Similarly, an elongated outlet 24 for ventilation 20 extends along a rear side 25 of the outer surface of shelter 2 and communicates ventilation 20 with the outer side of shelter 1. Ventilation 20 has upper and lower faces 26, 27 opposite each other themselves and opposite side faces 28.
    The upper and lower faces 26, 27 of the ventilation 20 converge with each other from the opening 22, in such a way that the cross-sectional area of the ventilation 20 is reduced, extending to the ventilation 20. The ventilation 20 therefore has a restricted section 29, in which the cross-sectional area of ventilation 20 is smaller than the cross-sectional area of ventilation 20 in opening 22. The upper and lower faces 26, 27 are arched, although it is understood that the arrangement is not limited to them.
    The restricted section 29 of the hot air ventilation 20 generates a Venturi effect on the hot air ventilation 20 as the air flows along the ventilation 20, through the restricted section 29. The upper and lower faces 26, 27 of the ventilation 20 diverge towards each other towards outlet 24 of ventilation 20 of restricted section 29, such that the cross-sectional area of ventilation 20 at outlet 24 is greater than the cross-sectional area of ventilation 20 in restricted section 29.
    Although in the present embodiment the upper and lower faces 26, 27 of the ventilation 20 converge to form the restricted section 29, it will be appreciated that the ventilation arrangement 20 is not limited to this and that other arrangements are possible to form the restricted section 25, in which the cross-sectional area of ventilation 20 is reduced from opening 22 to ventilation 20. In another embodiment, one of the upper or lower faces 26, 27 of ventilation 20 extends parallel to the base of the shelter and the opposite face 26, 27 converges towards the flat face 26, 27 to form the restricted section 25. Alternatively or additionally, one or both side walls 25 of the ventilation 20 converge towards the opposite side wall 25 to form the restricted section 25 of ventilation 20. In yet another embodiment, ventilation may have an arcuate face and a section of that arcuate face converges towards a diametrically opposite section of the arcuate face.
    Although in the present embodiment the ventilation 20 has a single hot air channel, it will be appreciated that, in an alternative embodiment, the ventilation has a series of hot air channels that extend from the food preparation chamber outside the shelter . In an alternative embodiment, for example, the hot air ventilation has a series of adjacent channels (not shown), each with converging upper and lower walls. Alternatively, ventilation has a series of adjacent channels formed by vertical columns arranged in ventilation (not shown), in which each vertical column has side walls that converge towards an opposite side wall to form restrictions on ventilation.
    A cooling air channel 30 is formed in the shelter 1, through which cooling air is drawn to cool the shelter 1 and other components disposed in the shelter 1. The cooling air channel 30 includes one or more cooling air passages. 32a, 32b formed in shelter 1 which are in fluid communication with each other. The cooling air channel 30 has a cooling air inlet 33 at the base 34 of the shelter 1, such that air can flow to the cooling air channel 30 on the outside of the shelter 1.
    The cooling air channel 30 has an outlet 35 that communicates with the restricted section 29 of the hot air ventilation 20. The outlet 35 is formed by an opening in the upper face 26 of the hot air ventilation 20. The outlet 35 is formed halfway along the restricted section 29 of the hot air vent 20, in order to generate reduced static pressure at the outlet 35 due to the Venturi effect generated as the air flows through the hot air vent 20.
    Although in the present embodiment the outlet 35 of the cooling air channel is formed on the upper face 26 of the hot air vent 20, it will be appreciated that the outlet 35 can be arranged to communicate with any part of the restricted section 29 of the hot air ventilation 20.
    The housing 1 additionally comprises a component chamber 37. The component chamber 37 is arranged in an upper part of the housing 1 and the motor 15 for directing the fan 14 is arranged in the component chamber 37 along with other components (not shown). The component chamber 37 communicates with the cooling air channel 30, so that the cooling air flows through the component chamber 37 when the cooling air flows along the cooling air channel 30.
    The food preparation chamber 4 is arranged in two parts, an upper part 4a and a lower part 4b.The lower part 4b is releasable from the upper part 4a, in order to be removable from the upper part 4a to allow access to the preparation chamber of food 4. The lower part 4b comprises a lower section of the shelter 1 and the inner wall 5, including the air-permeable section 10 of the inner wall 5 and a handle 38 to assist in removing the lower part 4b from the upper part 4a. The lower part 4b therefore forms an arrangement in the form of a basket or bowl, with an upper opening, such that food products can be placed in or removed from the food receiving space 6.
    A control panel 39 is mounted next to the shelter to allow control of the operation of the appliance, such as the operating time and temperature in the food preparation chamber 4.
    The operation of the food preparation apparatus will now be described with reference to Figure 1.
    The user initially removes the bottom part 4b of the food preparation chamber 3 from the shelter 1 by maneuvering the handle 38, so that the bottom part 4b separates from the top part 4a and allows the user to have access to the food receiving space 5. The user then places the food products to be heated and / or cooked in the food receiving space 6, placing them on the air-permeable section 10. Positioning the food products on the air-permeable section 10 allows hot air is blown through the food to increase the heating of the food due to the hot air flow and allows liquid food, such as water and oil, to fall through the air permeable section 10 of the food receiving space 6.
    The upper and lower parts 3a, 3b of the food preparation chamber 3 are then reconnected so that they are flat with each other. The user is then able to operate the apparatus through the control panel 39. When operating the apparatus, the heater 16 is operated to emit heat and the fan 14 is operated to circulate an air flow in the preparation chamber. food 4.
    During the operation of the heater 16, it heats the food in two different ways, radiating heat to heat the food products directly in the food receiving chamber 4 and heating the air flowing through it using the fan 14 that circulates hot air to heat the food. food products.
    The fan 14 draws hot air heated by the heater 16 through the air discharge opening 13 by means of the low pressure generation next to it. The hot air is then removed through the fan 14 and expelled at high pressure by the fan 14 to the air orientation passage 7 defined between the inner surface 3 of the shelter and the inner wall 5. The air orientation passage 7 guides the hot air flow towards the bottom part 4b of the food preparation chamber 4. The hot air flow then successively flows through the air-permeable section 10, the food receiving space 6 and the discharge opening 13.
    When the air flow moves through the food receiving space 6, it flows over the food products disposed therein and acts to heat the food products. It will be appreciated that the air flow over food products includes each of the air flows through, through and / or around the food products. Water and fat are discharged from food products and enter the air flow to form particles of oil and steam. The air then flows through the heater 16 to raise the air temperature again and is directed back towards the fan 14. The air then circulates in the food preparation chamber 4. The pressure in the food preparation chamber 4 increases with as steam is generated by evaporating water discharged from food products.
    As the hot air is expelled by the fan 14, a portion of the high pressure air flow is expelled towards the hot air ventilation 20 which extends between the food preparation chamber 4 and the outside of the shelter 1. This hot air is therefore forced to flow into the hot air vent 20 to be expelled through the vent 20 to the outside of the shelter. The cross-sectional area of ventilation 20 falls along the flow path formed by ventilation 20 from ventilation opening 22 to the restricted section 29, in order to generate Venturi effect on ventilation 20. The air velocity increases as the temperature decreases. ventilation cross-sectional area 20 towards restricted section 29. Consequently, the static pressure is reduced and reduced static pressure is formed in the restricted section 29.
    The reduced static pressure in restricted section 29 indicates that low static pressure is formed at outlet 35 to the cooling air channel 30. The cooling air in the cooling air channel 30 is therefore removed from the cooling air channel 30 through outlet 35 and into the hot air ventilation flow path 20.
    An air flow is then produced in the cooling air channel 30 as air is deposited along the cooling air channel 30 to the cooling air outlet 35 due to the reduced static pressure at outlet 35 and air from New cooling is conducted to the cooling air channel 30 through the inlet 33 to the cooling air channel 30. The fresh air introduced through the inlet 33 is under atmospheric temperature and will therefore act to remove heat from the shelter 1 and thus reduce the temperature of the shelter 1.
    The combined hot air expelled from the food preparation chamber 4 and the cooling air deposited through the outlet 35 of the cooling air channel 30 for ventilation 20 is then exhausted through the ventilation outlet 24 outside the shelter 1. At As the combined air flows through the ventilation 20 from the restricted section 29 to the ventilation outlet 24, the cross-sectional area of the flow path in the ventilation 20 increases as the opposite faces diverge. The velocity of the fluid therefore falls towards the ventilation outlet 24. As a result, the velocity of the combined air flowing from the shelter 1 is minimized.
    It will be appreciated that the combined air flow will be at a lower temperature than that of hot air and other fluids expelled only from the food preparation chamber and therefore the likelihood of damage or injury caused by the fluid that has been exhausted through of hot air ventilation 20 is minimized.
    In addition, an advantage of the above arrangement is the fact that the cooling air is deposited through the cooling air channel 30 and is exhausted from shelter 1 without the need for an additional fan or other components to create a flow. The reliability of the cooling system, therefore, increases with respect to the conventional appliance, due to the absence of components or moving parts in the cooling system. In addition, the noise level generated by the device is minimized.
    The cooling air is also deposited through the component chamber 37, which is in fluid communication with the cooling air channel 30. The air flowing through the component chamber 37 will therefore conduct heat away from the components disposed therein. and, in this way, the reliability of these components will be greater.
