Kitchen air conditioning system

Abstract

A kitchen air conditioning system includes an air conditioning component and a fume extraction component. The air outlet channel of the fume extraction component is bifurcated into a first air outlet channel and a second air outlet channel. A wind valve for switching the first air outlet channel to be connected to a fan air outlet or the second air outlet channel to be connected to the fan air outlet is provided at the bifurcation of the air outlet channel. A first heat exchanger is provided in the first air outlet channel. When the compressor is in a working state, the refrigerant flowing in the refrigerant pipeline drives the wind valve to rotate to a position where the first air outlet channel is opened and the second air outlet channel is closed. When the compressor is not in a working state, the wind valve rotates to a position where the second air outlet channel is opened and the first air outlet channel is closed under the action of gravity. The kitchen air conditioning system uses the pressure difference between the high-pressure exhaust pipeline and the low-pressure suction pipeline of the refrigeration system to drive the wind valve to open and close, so as to realize the switching of the air outlet channel. The wind valve does not need to be additionally installed with a push rod motor or other mechanical driving mechanism. The structure is simple and the operation is stable and reliable.

Description

Technical Field

[0001] The invention relates to an air conditioning system, in particular 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 hot and 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 existing kitchen air conditioner is often independent of the kitchen range hood, and there is no mutual cooperation between the two. For the integrated kitchen air conditioner, due to the limited installation space, the heat generated during the working process cannot be taken away in time and effectively, thus affecting the use effect of the air conditioner. For this reason, the applicant has previously invented a kitchen air conditioning system in which a heat exchanger is installed inside the range hood. In the cooling mode, the heat exchanger inside the range hood is used as a condenser, and the heat generated can be taken away by the oil smoke, thereby improving the energy efficiency of the air conditioner. In addition, according to whether the air conditioner is started, the air valve in the exhaust channel of the range hood can be rotated accordingly to open or close the corresponding exhaust channel. The existing air valve is usually driven by a push rod motor or other mechanical structure. This air valve driving method is relatively common, and the mechanical driving method has hidden dangers of failure. In summary, the existing kitchen air conditioning system needs to be further improved. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system with adaptively switchable air outlet channels in view of the above-mentioned existing technical status.

[0004] 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, the oil fume suction component includes a fan and an air outlet channel connected to the fan air outlet, and is characterized in that: the air outlet channel is bifurcated into a first air outlet channel and a second air outlet channel, and an air valve for switching the first air outlet channel to be connected to the fan air outlet or the second air outlet channel to be connected to the fan air outlet is provided at the bifurcation of the air outlet channel, the first heat exchanger is arranged in the first air outlet channel, when the compressor is in a working state, the refrigerant flowing in the refrigerant pipeline drives the air valve to rotate to a position where the first air outlet channel is opened and the second air outlet channel is closed, and when the compressor is not in a working state, the air valve rotates to a position where the second air outlet channel is opened and the first air outlet channel is closed under the action of gravity.

[0005] Preferably, the refrigerant pipeline between the first heat exchanger and the second heat exchanger is disconnected and divided into a first section of the refrigerant pipeline and a second section of the refrigerant pipeline. The first section of the refrigerant pipeline is connected to the second section of the refrigerant pipeline through a connecting pipe.

The other end of the air valve is fixed with a second magnetic body and abuts against the connecting pipe, and the second magnetic body and the first magnetic body are attracted by opposite sexes. In this way, when the compressor is working, the refrigerant flowing in the pipeline drives the first magnetic body to move, and the air valve swings upward. When the compressor stops working, the air valve swings downward under the action of its own weight, and the first magnetic body moves synchronously in the pipeline, thereby realizing the switching of the air outlet duct.

[0006] In order to avoid refrigerant leakage, the port of the first section of the refrigerant pipeline is provided with a first connection port, the port of the second section of the refrigerant pipeline is provided with a second connection port, and the connection pipe is sealed and connected between the first connection port and the second connection port.

[0007] Further preferably, the first heat exchanger is a condenser, and the second heat exchanger is an evaporator. In this way, when the system works in cooling mode, the refrigerant flows from the condenser to the evaporator, thereby driving the air valve to swing upward, thereby opening the first air outlet channel and closing the second air outlet channel.

[0008] In order to prevent the oil smoke from polluting the first heat exchanger, an oil smoke purification device is installed in the first air outlet channel, and the oil smoke purification device is arranged at the front end of the first heat exchanger.

[0009] Further preferably, an indoor unit is installed in the kitchen, the second heat exchanger is installed in the indoor unit, the indoor unit is provided with an air inlet and an air outlet, the air inlet is connected to the outside, and the air outlet is connected to the kitchen.

[0010] In order to make full use of the corner of the kitchen, the indoor unit is installed in the corner of the kitchen upper cabinet, and the compressor is integrated on the range fumes suction component.

[0011] In order to ensure that the air passing through the second heat exchanger can be smoothly replenished into the kitchen, a heat exchange fan is installed in the indoor unit near the air outlet, and the heat exchange fan is located between the second heat exchanger and the air outlet.

[0012] As a preferred embodiment of any of the above schemes, a throttling component is installed on the refrigerant pipeline between the first heat exchanger and the second heat exchanger.

[0013] Compared with the prior art, the advantages of the present invention are: the air outlet channel of the kitchen air conditioning system is bifurcated into a first air outlet channel and a second air outlet channel, and the pressure difference between the high-pressure exhaust pipeline and the low-pressure suction pipeline of the refrigeration system constitutes a pressure source for driving the opening and closing movement of the air valve, thereby realizing the switching of the air outlet channel, and the air valve does not need to be additionally installed with a push rod motor or other mechanical driving mechanism, and has a simple structure, stable and reliable operation. In addition, the first heat exchanger is arranged in the first air outlet channel, which is conducive to the oil smoke taking away the heat of the first heat exchanger, thereby improving the energy efficiency of the air conditioner.

[0018] like Figure 1 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 specifically 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 throttling component 10 is installed on the refrigerant pipeline 14 between the first heat exchanger 12 and the second heat exchanger 13. 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.

[0019] The range fumes extractor assembly 2 has a housing 200, in which a fan 20 is installed, and an air outlet channel 21 is provided at the rear end of the air outlet of the fan 20. The air outlet channel 21 is bifurcated into a first air outlet channel 22 and a second air outlet channel 23, and an air valve 3 is provided at the bifurcation of the air outlet channel 21. By switching the air valve 3, the first air outlet channel 22 can be connected to the air outlet of the fan 20 or the second air outlet channel 23 can be connected to the air outlet of the fan 20.

[0020] like Figure 2 and Figure 3As shown, in this embodiment, the refrigerant pipeline between the first heat exchanger 12 and the second heat exchanger 13 is disconnected and divided into a first section of the refrigerant pipeline 141 and a second section of the refrigerant pipeline 142. The first section of the refrigerant pipeline 141 is provided with a first connection port 143 at its port, and the second section of the refrigerant pipeline 142 is provided with a second connection port 144 at its port, and the connecting pipe 4 is sealed and connected between the first connection port 143 and the second connection port 144. A slidable first magnetic body 5 is provided in the connecting pipe 4, one end of the air valve 3 is rotatably connected to a support body inside the air outlet channel, such as the air valve 3 can be rotatably connected to the inner wall of the air outlet channel 21, and the other end of the air valve 3 is fixed with a second magnetic body 6 and abuts against the connecting pipe 4, and the second magnetic body 6 and the first magnetic body 5 are attracted to each other by opposite sexes, thereby ensuring that the air valve 3 can always keep synchronous movement with the first magnetic body 5, and at the same time solving the sealing problem between the connecting pipe 4 and the air valve 3.

[0021] In this embodiment, the compressor 11 and the first heat exchanger 12 are integrated on the oil fume suction assembly 2, and the first heat exchanger 12 is arranged in the first air outlet channel 22. In order to prevent the oil fume from polluting the first heat exchanger 12, an oil fume purification device 7 is also installed in the first air outlet channel 22, and the oil fume purification device 7 is arranged at the front end of the first heat exchanger 12. Generally, the oil fume purification device 7 can adopt various front-end electrostatic purification devices disclosed in the prior art, and the specific structure is not described here.

[0022] The kitchen air conditioning system has an indoor unit 8. In this embodiment, the indoor unit 8 is installed in the corner of the kitchen upper cabinet 9. The indoor unit 8 has an air inlet 81 and an air outlet 82. The air inlet 81 is connected to the outside, and the air outlet 82 is connected to the kitchen. The second heat exchanger 13 is installed in the indoor unit 8. In addition, a heat exchange fan 83 is also installed in the indoor unit 8.

[0023] The air conditioning component of the kitchen air conditioning system only works in the cooling mode. At this time, the first heat exchanger 12 is the condenser, the second heat exchanger 13 is the evaporator, the first section of the refrigerant pipeline 141 is the high-pressure exhaust pipeline, and the second section of the refrigerant pipeline 142 is the low-pressure suction pipeline. There is a pressure difference between the two, which drives the refrigerant to flow from the condenser to the evaporator along the connecting pipe 4. Therefore, the first magnetic body 5 can be driven to rotate clockwise along the connecting pipe 4, and then the air valve 3 can be driven to swing upward, that is, rotate clockwise until the air valve 3 rotates to abut against the second connecting port 144, the first air outlet channel 22 is fully opened, and the second air outlet channel 23 is fully closed, and the oil smoke is discharged from the first air outlet channel 22, and the first heat exchanger 12 can be cooled during the discharge process, thereby improving the air conditioning cooling effect.

[0024] When the air conditioning assembly stops working, the air valve 3 swings downward under its own weight, that is, rotates counterclockwise until the air valve abuts against the first connection port 143. At this time, the first air outlet channel 22 is completely closed, and the second air outlet channel 23 is completely opened, and the oil smoke is discharged from the second air outlet channel 23.
