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, and the quality of the kitchen air environment directly affects the mood of the cook. During the cooking process, a large amount of smoke is often generated in the kitchen. In the hot summer and cold winter, the external environment will affect the user's experience. Users have an increasingly strong demand for range hoods to blow cold air in summer and hot air in winter, thereby improving the cooking experience. To this end, people have invented various kitchen air conditioners to cool or heat the kitchen air. Existing kitchen air conditioners usually adopt an internal and external split type, that is, the external unit is located outdoors, the internal unit is located indoors, and the internal and external units each have a motor fan. The connection method of the internal and external split type 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 installation is relatively inconvenient. Although, there are also products such as air-conditioning hoods, that is, air-conditioning components are added on the basis of the range hood platform, which can realize all the functions of the range hood and the function of the air conditioner at the same time. However, these air-conditioning hoods often simply merge the functions of a traditional air-conditioning indoor unit with a traditional range hood. The air-conditioning outdoor unit still needs to be installed separately outdoors. This type of air-conditioning range hood is not integrated enough and the installation is more complicated. Moreover, the pipe and line connections between the indoor and outdoor units of the air-conditioning will also damage the wall.

[0003] In addition, in addition to using refrigerators to refrigerate and freeze food in the kitchen, people usually use incubators to keep food warm or cold. Existing incubators are placed independently on the kitchen countertop, which not only takes up space, but is also completely independent of the range hood and air conditioner, and has no connection with the kitchen air conditioning system. In summary, the existing kitchen air conditioning system needs to be further improved. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system with a compact structure and integrated fresh air, air conditioning and insulation box functions in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: the kitchen air conditioning system includes an air conditioning component and a fume extraction 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, the fume extraction component has a casing, and a smoke exhaust passage is arranged in the casing, characterized in that: the air conditioning component includes an outer shell, the outer shell is provided with a fresh air inlet connected to the outside and a fresh air outlet connected to the kitchen room, the first heat exchanger is installed in the outer shell, the second heat exchanger is installed in the smoke exhaust passage, an insulation box is installed inside the casing, a third heat exchanger is installed in the insulation box, and a three-way reversing valve for switching the third heat exchanger to be connected to the first heat exchanger or the second heat exchanger is installed on the refrigerant pipeline.

[0006] Preferably, the first port of the three-way reversing valve is connected to the third heat exchanger, the second port of the three-way reversing valve is connected to the refrigerant pipeline between the compressor and the first heat exchanger, and the third port of the three-way reversing valve is connected to the refrigerant pipeline between the compressor and the second heat exchanger.

[0007] Further preferably, a first throttling device is installed on the refrigerant pipeline between the second heat exchanger and the first heat exchanger, and a second throttling device is installed on the refrigerant pipeline between the third heat exchanger and the first heat exchanger.

[0008] In order to improve the heat exchange effect of the second heat exchanger, the oil fume extraction component includes an oil fume extraction fan installed in the casing, the exhaust channel is formed downstream of the air outlet of the oil fume extraction fan, and an oil fume purification device is also installed in the exhaust channel, and along the path of the oil fume flow, the oil fume purification device is located upstream of the second heat exchanger.

[0009] In order to make the internal structure of the casing of the oil fume suction component more reasonable, the oil fume suction fan is a horizontally arranged centrifugal fan, and the heat preservation box is arranged above the oil fume suction fan.

[0010] In order to make the temperature field in the heat preservation box more uniform, a first fan blowing air toward the third heat exchanger is also installed in the heat preservation box.

[0011] In order to smoothly replenish fresh air into the kitchen, a second fan is installed in the housing, and the second fan is located in the air duct between the fresh air inlet and the first heat exchanger.

[0012] Further preferably, the shell is suspended above the kitchen ceiling.

[0013] The compressor can be installed in a plurality of different positions. Preferably, the compressor is integrated in the housing of the air conditioning component or in the casing of the fume extraction component.

[0014] Compared with the prior art, the advantages of the present invention are: the kitchen air conditioning system installs the first heat exchanger in the fresh air duct, the second heat exchanger in the smoke exhaust duct, and the third heat exchanger in the casing of the range fumes extraction component. The system structure is compact, and by switching the three-way reversing valve, the third heat exchanger can be connected to the first heat exchanger or the second heat exchanger. The system can not only cool or heat the outdoor fresh air and then supplement it to the kitchen room, but also make the insulation box on the casing of the range fumes extraction component become a constant heat box or a constant cold box, thereby expanding the function of the system.

[0019] The present invention is further described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 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. 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.

[0021] The air conditioning assembly 1 of this embodiment includes an outer shell 10, which is suspended above the kitchen ceiling (not shown in the figure). The outer shell 10 is provided with a fresh air inlet 100 connected to the outside and a fresh air outlet 101 connected to the kitchen room. A fresh air passage 17 is formed in the outer shell 10, and an air supply outlet (not shown in the figure) connected to the fresh air outlet 101 can be provided on the kitchen ceiling.

[0022] The first heat exchanger 12 and the second fan 18 are installed in the fresh air passage 17, and along the path of the fresh air flow, the second fan 18 is located upstream of the first heat exchanger 12. The second fan 18 constitutes a fresh air fan, and under the action of the second fan 18, the outdoor fresh air passes through the first heat exchanger 12 to supplement the kitchen. In addition, in order to input clean fresh air into the kitchen, a fresh air purification device (not shown) can also be installed in the fresh air passage 17.

[0023] The oil fume suction assembly 2 has a housing 20, in which an oil fume suction fan 22 is installed. The oil fume suction fan 22 is a centrifugal fan, and a smoke exhaust passage 21 is formed downstream of the air outlet of the oil fume suction fan 22. An oil fume purification device 23 and a second heat exchanger 13 are installed in the smoke exhaust passage 21, and along the path of the oil fume flow, the oil fume purification device 23 is located upstream of the second heat exchanger 13, so that the oil fume flows through the second heat exchanger 13 after being purified, thereby preventing the second heat exchanger 13 from being contaminated by the oil fume.

[0024] The compressor 11 of this embodiment is integrated inside the casing 20 of the range fumes extraction assembly 2. Of course, the compressor 11 can also be installed inside the casing 10 of the air conditioning assembly 1, or installed above the kitchen ceiling.

[0025] An insulation box 3 is installed in the casing 20, and the insulation box 3 is located above the range fumes exhaust fan 22. A third heat exchanger 4 is installed in the insulation box 3, and a three-way reversing valve 5 is installed on the refrigerant pipeline 14. By switching the three-way reversing valve 5, the third heat exchanger 4 can be connected to the first heat exchanger 12 or the third heat exchanger 4 can be connected to the second heat exchanger 13. The first port 51 of the three-way reversing valve 5 is connected to the third heat exchanger 4, the second port 52 of the three-way reversing valve 5 is connected to the refrigerant pipeline 14 between the compressor 11 and the first heat exchanger 12, and the third port 53 of the three-way reversing valve 5 is connected to the refrigerant pipeline 14 between the compressor 11 and the second heat exchanger 13. In addition, a first throttling device 15 is installed on the refrigerant pipeline 14 between the second heat exchanger 13 and the first heat exchanger 12, and a second throttling device 16 is installed on the refrigerant pipeline 14 between the third heat exchanger 4 and the first heat exchanger 12. In addition, in order to make the temperature field of the heat preservation box 3 more uniform, a first fan 6 for blowing air toward the third heat exchanger 4 is installed in the heat preservation box 3 .

[0026] The system works as follows:

[0027] like Figure 2As shown, on the basis of the first heat exchanger 12 being connected with the second heat exchanger 13, the first port 51 of the three-way reversing valve 5 is connected with the third port 53, so that the third heat exchanger 4 is connected with the first heat exchanger 12. At this time, the second heat exchanger 13 and the third heat exchanger 4 are used as condensers, and the first heat exchanger 12 is used as an evaporator. The refrigerated fresh air comes out from the fresh air outlet 101 and is supplemented to the kitchen room. The oil smoke in the smoke exhaust channel 21 takes away the heat of the second heat exchanger 13, thereby improving its heat exchange effect, and the insulation box 3 becomes a constant temperature box.

[0028] like Figure 3 As shown, on the basis of the first heat exchanger 12 being connected to the second heat exchanger 13, the first port 51 of the three-way reversing valve 5 is connected to the second port 52, so that the third heat exchanger 4 is connected to the second heat exchanger 13. At this time, the second heat exchanger 13 is used as a condenser, and the first heat exchanger 12 and the third heat exchanger 4 are used as evaporators. The refrigerated fresh air comes out from the fresh air outlet 101 and is supplemented to the kitchen room. The oil smoke in the smoke exhaust channel 21 takes away the heat of the second heat exchanger 13, thereby improving its heat exchange effect, and the insulation box 3 becomes a constant cooling box.
