Description

Technical Field

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

[0002] The kitchen is the main place for people to 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. The basic form of the existing kitchen air conditioner is not much different from that of the ordinary air conditioner. Generally, there are two forms. One is the internal and external unit split type, 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 internal and external unit split kitchen air conditioner needs to be connected through a pipeline, and a hole needs to be opened on the wall, which destroys the decoration. An external unit needs to be hung outside, and the structure is not compact enough and the overall appearance is not beautiful. The other is that the internal and external units are integrated structures, which can use a double-axis motor or two motors. The internal and external unit integrated machine usually includes a mobile air conditioner and a window machine. When the mobile air conditioner is used, it is necessary to manually connect the heat dissipation hose and put the hose outside the window, which is inconvenient to use; the window machine needs to open a square hole with a large area on the wall to put the machine in, and can be moved out when not in use, leaving a square hole on the wall. Although it can be blocked with other things, it is troublesome and destroys the decoration. In addition, the existing kitchen air conditioner is not organically combined with the range hood, and the system performance needs to be optimized. In summary, the existing kitchen air conditioning system needs to be further improved. Summary of the invention

[0015] The present invention is further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system in this embodiment includes an air conditioning component 1 and a fume extraction component 2. 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.

[0017] The air conditioning assembly 1 has a housing 10, which is installed above the kitchen ceiling 9. The housing 10 is provided with an air inlet 16 and an air outlet 17. The air inlet 16 is connected to the outside, and the air outlet 17 is connected to the kitchen through the air supply port 91 on the kitchen ceiling 9. The compressor 11 and the first heat exchanger 12 are installed inside the housing 10. A fresh air purification device 18 and an air supply fan 19 are also installed inside the housing 10. The air outlet of the air supply fan 19 faces the first heat exchanger 12. The first heat exchanger 12 is close to the air outlet 17 on the housing 10. The fresh air purification device 18 is located in the air duct between the air inlet 16 and the air inlet of the air supply fan 19. In this way, the outdoor fresh air can be purified before being sent into the kitchen, so that the air sent into the room is cleaner.

[0018] The oil fume extraction component 2 adopts an oil fume extractor, which includes a fan 22. The rear end of the fan 22 outlet forms an exhaust passage 21. The second heat exchanger 13 is installed in the exhaust passage 21 at the rear end of the fan outlet. A liquid collecting box 8 is installed below the second heat exchanger 13 to collect spray water. In addition, an oil fume purification device 23 is installed in the exhaust passage 21 between the fan 22 outlet and the second heat exchanger 13 to prevent the oil fume from polluting the second heat exchanger 13.

[0019] A first liquid storage container 3 and a second liquid storage container 4 are provided inside the housing 10, the lower part of the compressor 11 is located in the first liquid storage container 3, and the lower part of the first heat exchanger 12 is located in the second liquid storage container 4. A spray head 51 for spraying the second heat exchanger is provided in the smoke exhaust passage 21, the first liquid storage container 3 and the spray head 51 are connected through a first water channel, and the second liquid storage container 4 and the spray head 51 are connected through a second water channel.

[0020] In this embodiment, the first liquid storage container 3 is provided with a liquid inlet pipe 31 and a first liquid outlet pipe 32, the second liquid storage container 4 is provided with a second liquid outlet pipe 41, the first liquid outlet pipe 32, the second liquid outlet pipe 41 and the liquid inlet end of the spray pipe 5 are connected through a three-way valve 6, the spray pipe 5 is installed with a water pump 7, the spray head 51 is installed at the head of the spray pipe 5, and the liquid outlet end of the spray pipe 5 extends into the smoke exhaust channel 21. In this way, by switching the three-way valve 6, one of the first liquid storage container 3 and the second liquid storage container 4 can be connected to the spray head 51.

[0021] By switching the four-way valve 15, the system can switch between cooling and heating modes. In the cooling mode, the first heat exchanger 12 is an evaporator and the second heat exchanger 13 is a condenser. Conversely, in the heating mode, the first heat exchanger 12 is a condenser and the second heat exchanger 13 is an evaporator.

[0022] In cooling mode, the evaporator of the air conditioner indoor unit, i.e., the first heat exchanger 12, generates condensed water, which is pumped into the spray pipe 5 and dissipates heat to the condenser, i.e., the second heat exchanger 13, through the spray head 51, thereby providing a heat exchange effect for the condenser and improving the air conditioner energy efficiency.

[0023] In the heating mode, the evaporator in the range hood, i.e., the second heat exchanger 13, is prone to frost. The compressor 11 in the air conditioner indoor unit generates heat continuously. The hot water generated by the waste heat of the compressor 11 is pumped into the spray pipe 5 and sprayed on the evaporator through the spray head 51. The heat of the hot water is used to defrost the evaporator, thereby ensuring that the air duct is unobstructed, thereby ensuring the range hood's oil fume absorption performance.
