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

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

[0021] like Figures 1 to 3 As shown, the kitchen air conditioning system of 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.

[0022] The air conditioning assembly 1 has a housing 10, which is installed above the kitchen ceiling 8. 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 81 on the kitchen ceiling 8. 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.

[0023] In addition, a liquid storage container 3 is provided inside the housing 10, the lower part of the compressor 11 is located in the liquid storage container 3, the liquid storage container 3 is connected with a liquid inlet pipe 4 and a liquid outlet pipe 5, a water pump 6 is installed on the liquid inlet pipe 4 and the liquid outlet pipe 5, and the head of the liquid outlet pipe 5 has a spray head 51. Water is pre-stored in the liquid storage container 3, and when the compressor 11 is working, the waste heat generated can heat the water in the liquid storage container 3.

[0024] The oil fume extraction component 2 adopts an oil fume extractor, which includes a fan 22 . A smoke exhaust passage 21 is formed at the rear end of the outlet of the fan 22 . An electrostatic purification device 7 is installed in the smoke exhaust passage 21 .

[0025] like Figures 3 to 5 As shown, the electrostatic purification device 7 of this embodiment includes a positive plate structure and a negative plate structure, the second heat exchanger 13 constitutes the positive plate structure, and the spray head 51 extends into the smoke exhaust channel 21 and can spray toward the second heat exchanger 13. A heating device is installed on the negative plate structure. Specifically, the positive plate structure includes a positive plate outer frame 71 and a positive plate 72 arranged in the positive plate outer frame and spaced apart, and the negative plate structure includes a side plate 73 and a negative plate 74 connected to the side plate, and the negative plate 74 is spaced apart from the positive plate 72. The heating device is an electric heating film 75 attached to the side plate 73.

[0026] By switching the four-way valve 15, the cooling and heating modes can be switched. 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.

[0027] In cooling mode: the condenser inside the range hood dissipates heat, and the condenser serves as the positive plate 72 of the electrostatic purification device 7. The surface is very clean and the working performance can be guaranteed all the time. The negative plate 74 accumulates oil. After working for a period of time, the cleaning mode can be turned on. The electric heating film 75 attached to the side plate 73 of the negative plate 74 can heat the negative plate 74 to about 200 degrees, and then the hot water generated by the waste heat of the compressor 11 is used to rinse the electrostatic purification device 7, so as to achieve the purpose of regularly cleaning the negative plate 74, and finally the electrostatic purification device 7 is heated and dried.

[0028] In heating mode: the evaporator in the range hood serves as the positive plate of the electrostatic purification device 7. At this time, the temperature of the positive plate is extremely low and it is easy to frost. The electric heating film 75 attached to the side plate 73 of the negative plate 74 can heat the negative plate 74 to about 200 degrees. The evaporator assembled with the negative plate 74 absorbs the heat generated by the negative plate 74 to prevent the positive plate from frosting and blocking the oil fume passage.
