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 with a compact structure and capable of combining an air conditioning system and a total heat exchanger to effectively utilize the waste heat of cooking fumes in response to the above-mentioned existing technical status.

[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 kitchen room, 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 inside of the cabinet and / or cupboard.

[0007] The total heat exchanger can be installed at multiple positions of the oil fume suction component. 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 oil fume purification device and the total heat exchanger.

[0010] The second heat exchanger can be installed in multiple positions. Preferably, the second heat exchanger is installed in the air duct between the second air outlet and the air inlet of the cabinet and / or cupboard. In this way, the air discharged from the total heat exchanger can be discharged into the cabinet and / or cupboard after passing through the second heat exchanger.

[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] Preferably, 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 connect the first air inlet with the first air outlet.

[0013] In order to realize internal circulation, a ventilation hole connected with the first air inlet is opened on the kitchen ceiling.

[0014] Further preferably, the compressor and the second heat exchanger are both installed above the kitchen ceiling.

[0015] In order to provide warm air inside the cabinet or cupboard, the first heat exchanger is an evaporator and the second heat exchanger is a condenser. The warm air is sent into the cabinet or cupboard to achieve a dehumidification or drying effect.

[0016] 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 the total heat exchanger is integrated on the oil fume suction component, the structure is more compact, and two different working modes can be switched by switching the air valve. The oil fume suction component can be used alone and the oil fume is directly discharged to the outside, and the waste heat of the oil fume can be exchanged with the indoor air and discharged to the cabinet or cupboard to achieve a dehumidification or drying effect, thereby realizing the effective utilization of the waste heat of the oil fume.

[0019] Figure 3 This is a schematic diagram of the structure of the second embodiment of the present invention. DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1:

[0022] 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.

[0023] The oil fume extraction component 2 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. In the smoke exhaust passage 21, an oil fume purification device 22, a total heat exchanger 3 and a first heat exchanger 12 are arranged in sequence from front to back, so as to prevent the oil fume from contaminating the total heat exchanger 3 and the first heat exchanger 12.

[0024] The total heat exchanger 3 includes a housing 30, and a first air inlet 31, a second air inlet 32, a first air outlet 33, and a second air outlet 34 are formed on the housing 30. The first air inlet 31 is connected to the kitchen room through the vent 51 of the kitchen ceiling 5, the second air inlet 32 ​​is connected to the exhaust passage 21 of the range fumes suction assembly 2, the first air outlet 33 is connected to the outside or a public flue through the exhaust pipe 23, and the second air outlet 34 is connected to the inside of the cabinet 4 or the cupboard.

[0025] A wind valve 35 for switching wind direction and a fan 36 for providing wind force are installed in the housing 30, 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.

[0026] In this embodiment, the compressor 11 and the second heat exchanger 13 of the air conditioning assembly 1 are both installed above the kitchen ceiling 5, and the second heat exchanger 13 is located in the air duct between the second air outlet 34 and the air inlet 41 of the cabinet 4 or the cupboard air inlet.

[0027] The kitchen air conditioning system is mainly used to supply air to the cabinet 4 or the cupboard. When working, by switching the four-way valve 15, the first heat exchanger 12 is an evaporator, the second heat exchanger 13 is a condenser, and by switching the air valve 35, the system can work in the following two different modes:

[0028] In the first mode, the air valve 35 is in a vertical position, the range hood works alone, the compressor 11 is not turned on, and the oil smoke in the range hood enters the total heat exchanger 3 through the second air inlet 32, and is then discharged to the outside or the public flue through the first air outlet 33.

[0029] In the second mode, the air valve 35 is in a horizontal position, and the purified air in the range hood completes the first heat exchange with the first heat exchanger 12, i.e., the evaporator, in the smoke exhaust channel 21, and then enters the total heat exchanger 3 through the second air inlet 32, and completes the second heat exchange with the indoor air entering the total heat exchanger 3 from the first air inlet 31. The indoor air after heat exchange is discharged from the first air outlet 33 to the outdoors or a public flue, and the purified air after heat exchange is discharged from the second air outlet 34, and finally passes through the second heat exchanger 13, i.e., the condenser, to complete the third heat exchange, and then is discharged to the cabinet 4 to achieve a dehumidification effect, and then to the cupboard to achieve a drying effect.

[0030] Embodiment 2:

[0031] like Figure 3As shown, the kitchen air conditioning system in this embodiment includes the fume purification device 22, the first heat exchanger 12 and the total heat exchanger 3 from front to back in the exhaust passage 21. The remaining structure and working principle of this embodiment are the same as those of the first embodiment, and will not be described in detail here.
