Description

Technical Field

[0001] The invention relates to a kitchen air conditioning system. Background Art

[0002] The kitchen is the main place where people cook. The quality of the kitchen air environment directly affects the mood of the cook, especially in the hot summer, the stuffy environment of the kitchen brings great discomfort to the cook. For this reason, people have invented various kitchen air conditioners to cool the kitchen air.

[0003] The basic form of the existing kitchen air conditioner is not much different from that of ordinary air conditioners. Generally, the internal and external units are separated, that is, the external unit is located outdoors, and the internal unit is located indoors. The internal and external units each have a motor fan. The connection method of the kitchen air conditioner with internal and external units separated needs to be connected through pipes, and holes need to be opened on the wall, which damages the decoration. An external unit needs to be hung outside. The structure is not compact enough and the overall appearance is not beautiful. In addition, the existing kitchen air conditioners all have outdoor air inlets and indoor air outlets. The outdoor fresh air enters the air conditioner internal unit through the outdoor air inlet, and is replenished to the kitchen from the indoor air outlet after heat exchange in the heat exchanger. That is, the air conditioner works in the fresh air mode. For extreme weather such as hot summer or cold, due to the large temperature between the outdoor air and the indoor air, the air conditioner energy consumption is high, which is not conducive to energy saving, and the heat generated by the air conditioner heat exchange cannot be effectively utilized. It can be seen that the existing kitchen air conditioner is not organically combined with the range hood, and the heat generated by the air conditioner heat exchanger cannot be discharged through the range hood.

[0004] In addition, as people pay more and more attention to energy conservation and environmental protection, people not only pay attention to the pollution of the environment caused by the exhaust of oil smoke, but also begin to pay more and more attention to the problem of heat waste caused by the exhaust of oil smoke. However, during the operation of the current range hood, the heat carried by the exhaust oil smoke is not effectively utilized before being discharged into the public flue or outdoors, resulting in heat waste. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system which can effectively utilize the waste heat of cooking fumes by combining an air conditioning system and a total heat exchanger in view of the above-mentioned existing technical status.

[0007] Preferably, the air conditioning component has a casing, the total heat exchanger is installed inside the casing, and ventilation holes corresponding to the first air inlet, the second air inlet, the first air outlet, and the second air outlet are opened on the casing.

[0008] In order to enable the air valve to smoothly switch the wind direction, the total heat exchanger includes an outer shell, on which the first air inlet, the second air inlet, the first air outlet and the second air outlet are opened. The air valve is arranged inside the outer shell, and a block for cooperating with the air valve is installed on the relative inner wall of the outer shell.

[0010] The second heat exchanger can be installed in multiple positions. Preferably, the second heat exchanger is arranged inside the casing.

[0011] In order to prevent oil smoke from polluting the first heat exchanger, the oil smoke suction component adopts an oil smoke suction machine, which includes a fan, the rear end of the fan outlet forms the smoke exhaust channel, and the oil smoke filter is arranged at the front end of the first heat exchanger.

[0012] The compressor can be installed in multiple positions. Preferably, the compressor is integrated on the oil fume suction component.

[0013] The air valve can have two switching modes, the air valve can be switched to connect the second air inlet with the first air outlet, or switched to connect the second air inlet with the second air outlet, and the first air inlet with the first air outlet.

[0014] As a preferred embodiment of any of the above solutions, the first heat exchanger is an evaporator and the second heat exchanger is a condenser. In this way, warm air can be provided to the cabinet or cupboard.

[0015] Compared with the prior art, the advantages of the present invention are: the kitchen air conditioning system combines a total heat exchanger, an air conditioning system and an oil fume suction component, and can switch between two different working modes by switching the air valve. In one working mode, the oil fume suction component is used alone, and the oil fume in the range hood is directly discharged to the outside. In the other working mode, the waste heat of the oil fume is exchanged with the indoor air through heat and the air is discharged to the cupboard to achieve a dehumidification effect, and the air is discharged to the cupboard to achieve a drying effect, thereby realizing the effective utilization of the waste heat of the oil fume.

[0019] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system of this embodiment includes an air conditioning component 1, a fume extraction component 2 and a total heat exchanger 3. The air conditioning component 1 includes a compressor 11, a first heat exchanger 12 and a second heat exchanger 13. The compressor 11, the first heat exchanger 12 and the second heat exchanger 13 are connected through a refrigerant pipeline 14, and a four-way valve 15 is installed on the refrigerant pipeline 14. The working principle of the air conditioning component 1 is the same as that of the existing air conditioner, and will not be described in detail here.

[0020] The oil fume extraction component 2 of this embodiment adopts an oil fume extractor, and a centrifugal fan 20 is installed inside the oil fume extractor, and a smoke exhaust passage 21 is formed at the rear end of the outlet of the centrifugal fan 20.
