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

[0010] Preferably, an air supply fan and the second heat exchanger are installed in the casing, and the air supply fan is located at the front side of the second heat exchanger.

[0021] The present invention is further described in detail below with reference to the accompanying drawings. 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. A four-way valve 15 is installed on the refrigerant pipeline 14. By switching the four-way valve 15, the air conditioning working mode is switched. 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 extraction machine, which includes a fan housing 20 and a fan 21 installed in the fan housing. The compressor 11 is installed on the fan housing 20, and the rear end of the outlet of the fan 21 forms an exhaust passage 22. The first heat exchanger 12 and the oil fume purification unit 23 are installed in the exhaust passage 22, and the oil fume purification unit 23 is located at the front end of the first heat exchanger 12.

[0024] The air conditioning assembly 1 of this embodiment has a casing 10, which is installed above the kitchen ceiling 4, and a vent 41 is opened on the kitchen ceiling 4. A total heat exchanger 3, a second heat exchanger 13 and an air supply fan 16 are installed in the casing 10, and the air supply fan 16 is located at the front side of the second heat exchanger 13, and the total heat exchanger 3 is arranged at the rear side of the second heat exchanger 13. The total heat exchanger 3 includes a shell 30, and a first air inlet 31, a second air inlet 32, a first air outlet 33 and a second air outlet 34 are opened on the shell 30, and the second heat exchanger 13 is close to the second air outlet 34. Ventilation holes corresponding to the first air inlet 31, the second air inlet 32, the first air outlet 33 and the second air outlet 34 are opened on the casing 10. Among them, the first air inlet 31 is connected to the outdoors, the second air inlet 32 ​​is connected to the exhaust channel 22 of the fume suction component 2, the first air outlet 33 is connected to the outdoors or the public flue through the exhaust pipe 5, and the second air outlet 34 is connected to the kitchen room through the ventilation hole 41 on the kitchen ceiling 4.

[0025] A wind valve 35 for switching wind direction is installed in the housing 30, and a stopper 36 for cooperating with the wind valve 35 is installed on the opposite inner side wall of the housing 30. When the wind valve 35 is switched to a vertical position and abuts against the stopper 36, the second air inlet 32 ​​is connected to the second air outlet 34, and when the wind valve 35 is switched away from the stopper 36 and is in a horizontal position, the first air inlet 31 is connected to the second air outlet 34, and the second air inlet 32 ​​is connected to the first air outlet 33.

[0026] When the kitchen air conditioning system is working, by switching the air valve 35 and the four-way valve 15, the system can be switched between the following three different working modes.

[0027] The first mode is the internal circulation mode. At this time, 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 passes through the oil smoke purification unit 23 and enters the total heat exchanger 3 from the second air inlet 32, and supplies air to the kitchen room through the second air outlet 34, forming an internal circulation.

[0028] The second mode is the heating mode, the first heat exchanger 12 is an evaporator, and the second heat exchanger 13 is a condenser.

[0029] The air valve 35 is in a horizontal position. The purified air in the range hood completes the first heat exchange with the evaporator in the smoke exhaust channel 22, and then enters the total heat exchanger 3 through the second air inlet 32. The outdoor fresh air enters the total heat exchanger 3 after the second heat exchange through the condenser, and undergoes a third heat exchange with the air entering the total heat exchanger 3 from the second air inlet 32. Finally, warm air is provided to the kitchen room through the second air outlet 34, and the oil fume gas entering from the second air inlet 32 ​​is discharged through the first air outlet 33.

[0030] The third mode is the cooling mode, the first heat exchanger 12 is a condenser, the second heat exchanger 13 is an evaporator, the air valve 35 is in a horizontal position, and the purified air in the range hood completes the first heat exchange with the condenser in the smoke exhaust channel 22, and then enters the total heat exchanger 3 through the second air inlet 32. The outdoor fresh air enters the total heat exchanger 3 after the second heat exchange through the evaporator, and undergoes a third heat exchange with the air entering the total heat exchanger from the second air inlet 32, and finally provides cold air to the kitchen through the second air outlet 34, and the oil fume gas entering from the second air inlet 32 ​​is discharged to the outdoors through the first air outlet 33. Embodiment 2:

[0031] like Figure 3 and Figure 4 As shown, the total heat exchanger 3 of this embodiment is different from that of the first embodiment. A fresh air purification unit 17 is installed in the air inlet channel at the front end of the second heat exchanger 13, and the air valve 35 can be switched to the first air inlet 31 connected to the first air outlet 33, and the second air inlet 32 ​​connected to the second air outlet 34, or switched to the first air inlet 31 connected to the second air outlet 34.

[0032] When the kitchen air conditioning system is working, the system can be switched between the three working modes of external circulation mode, heating mode and cooling mode by switching the air valve 35 and the four-way valve 15. In the external circulation mode, the first air inlet 31 is connected to the second air outlet 34, and the outdoor fresh air is purified by the fresh air purification unit 17 and then replenished into the room; in the heating and cooling modes, the first air inlet 31 is connected to the first air outlet 33, and the second air inlet 32 ​​is connected to the second air outlet 34. Its specific working principle is the same as that of the first embodiment, and will not be described in detail here.
