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.

[0006] The technical solution adopted by the present invention to solve the above technical problems is as follows: the kitchen air conditioning system comprises an air conditioning component and an oil fume suction component, the air conditioning component comprises a compressor, an evaporator and a condenser, the compressor, the evaporator and the condenser are connected through a refrigerant pipeline, and is characterized in that: it also comprises a total heat exchanger, the total heat exchanger has a shell, the shell is provided with a first air inlet, a second air inlet, a first air outlet and a second air outlet, an air valve for switching wind direction is installed inside the shell, the first air inlet is connected to the kitchen room, the first air outlet is connected to the outdoors or a public flue, the second air outlet is connected to the air supply outlet inside the cabinet and / or cupboard, the exhaust channel of the oil fume suction component is connected to the second air inlet, an oil fume filter and the evaporator are installed in the exhaust channel, and the condenser is installed in the air duct between the second air outlet and the air supply outlet.

[0007] Preferably, a fan for providing wind power is also installed inside the housing.

[0008] In order to enable the air valve to smoothly switch the wind direction, a stopper for cooperating with the air valve is installed on the opposite inner side walls of the shell.

[0009] In order to prevent the oil smoke from polluting the evaporator in the smoke exhaust channel, the oil smoke filter is arranged at the front end of the evaporator.

[0010] The compressor and the condenser can have multiple installation positions. Preferably, the compressor is integrated on the range fumes suction assembly, and the condenser is arranged above the kitchen ceiling and close to the second air outlet of the air conditioning assembly.

[0011] The shell can be installed in multiple positions. Preferably, the shell is arranged above the kitchen ceiling, and the first air inlet is connected to the kitchen room through the ventilation hole on the kitchen ceiling.

[0012] 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.

[0013] 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 and discharged to the cabinet or cupboard to achieve a drying effect, thereby realizing the effective utilization of the waste heat of the oil fume.

[0017] 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, an evaporator 12 and a condenser 13, and the compressor 11, the evaporator 12 and the condenser 13 are connected through a 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.

[0018] The fume extraction component 2 adopts a range hood. In this embodiment, a top suction range hood is adopted. A centrifugal fan 20 is installed inside the range hood. A smoke exhaust channel 21 is formed at the rear end of the outlet of the centrifugal fan 20.

[0019] The total heat exchanger 3 is installed above the kitchen ceiling 5. The total heat exchanger 3 has a shell 30, and the shell 30 is provided with a first air inlet 31, a second air inlet 32, a first air outlet 33, and a second air outlet 34. The first air inlet 31 is connected to the kitchen room through the vent 51 on the kitchen ceiling 5, the second air inlet 32 ​​is connected to the exhaust passage 21 of the oil fume suction assembly 2, the first air outlet 33 is connected to the outdoors or a public flue, and the second air outlet 34 is connected to the air supply 41 inside the cabinet 4. The second air outlet 34 can also be connected to the air supply 41 inside the cupboard. In addition, an oil fume filter 22 and an evaporator 12 are installed in the exhaust passage 21, and the oil fume filter 22 is arranged at the front end of the evaporator 12, so as to prevent the oil fume from polluting the evaporator 12.

[0020] The housing 30 of the total heat exchanger 3 is internally provided with a wind valve 35 for switching wind direction and a fan 36 for providing wind force, and a stopper 37 for cooperating with the wind valve 35 is installed on the opposite inner side wall of the housing 30. When the wind valve 35 switches to a vertical position and abuts against the stopper 37, the second air inlet 32 ​​is connected to the first air outlet 33; when the wind valve 35 switches away from the stopper 37 and is in a horizontal position, the second air inlet 32 ​​is connected to the second air outlet 34, and the first air inlet 31 is connected to the first air outlet 33.
