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

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the kitchen air conditioning system includes an air conditioning component and an oil fume suction component, the air conditioning component includes a compressor, a first heat exchanger and a second heat exchanger, the compressor, the first heat exchanger and the second heat exchanger are connected through a refrigerant pipeline, and a four-way valve is installed on the refrigerant pipeline, characterized in that: a total heat exchanger is integrated on the oil fume suction component, the total heat exchanger has a first air inlet, a second air inlet, a first air outlet, a second air outlet and an air valve for switching wind direction, the first air inlet is connected to the outdoors, the first air outlet is connected to the outdoors or a public flue, the second air inlet is connected to the exhaust channel of the oil fume suction component, and the second air outlet is connected to the kitchen room.

[0007] The total heat exchanger can be installed at multiple positions of the western oil fume assembly. Preferably, the total heat exchanger is arranged in the exhaust passage, and an oil fume purification device is installed in the exhaust passage and at the front end of the total heat exchanger.

[0008] As a preferred solution, the first heat exchanger is arranged in the smoke exhaust channel and located at the rear end of the total heat exchanger.

[0009] As another preferred solution, the first heat exchanger is arranged in the smoke exhaust channel and is located between the total heat exchanger and the oil fume purification device.

[0010] The second heat exchanger can be installed in a plurality of different positions. Preferably, the second heat exchanger is installed in the air inlet channel at the front end of the first air inlet. In this way, the outdoor fresh air enters the total heat exchanger for heat exchange after heat exchange.

[0011] Preferably, 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 formed, the air valve is arranged inside the outer shell, a fan for providing wind force is installed inside the outer shell, and a block for cooperating with the air valve is installed on the relative inner wall of the outer shell.

[0012] Further preferably, the compressor and the second heat exchanger are both installed above the kitchen ceiling. A vent connected to the second air outlet is provided on the kitchen ceiling.
