Detailed ways

The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

Example 1:

As shown in FIGS. 1 and 2 , the kitchen air conditioning system of this embodiment includes an air conditioning assembly 1 and a range hood assembly 2 . The air conditioning assembly 1 includes a compressor 11 , a first heat exchanger 12 and a second heat exchanger 13 , and the compressor 11 , the first heat exchanger 12 and the second heat exchanger 13 are communicated through a refrigerant pipeline 14 , A throttle valve 18 is installed on the refrigerant line 14 between the first heat exchanger 12 and the second heat exchanger 13 , and a four-way valve (not shown in the figure) is installed on the refrigerant line 14 . By switching the four-way valve, the cooling mode and the heating mode can be switched. In the cooling mode, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator. In the heating mode, the first heat exchange The heat exchanger 12 is an evaporator, and the second heat exchanger 13 is a condenser. The working principle of the air conditioning assembly 1 is the same as that of the existing air conditioner, and will not be described here.

The oil fume assembly 2 includes a fan assembly 21, a smoke exhaust channel 22 communicated with the air outlet of the fan, and an air intake channel 23 communicated with the air inlet of the fan. The fan in the range hood has two functions: it can not only be used as the fan of the range hood to achieve the effect of exhausting oil fume, but also can provide air intake for the air conditioning system, help the heat exchange of the air conditioning system, and provide cooling or heating for the kitchen. Effect.

The first heat exchanger 12 is arranged in the exhaust channel. This arrangement, on the one hand, can provide a flue gas discharge passage for the oil fume exhaust system, and on the other hand, this arrangement simplifies the installation of the first heat exchange assembly, and the overall structure is compact, and unlike traditional air conditioning assemblies, there is no need to install The outdoor unit equipped with the heat exchange component is installed outside the user's room. This structure is more conducive to the operation of the staff, and the installation process is safer and more reliable. In the third aspect, the length of the exhaust channel is large and the space is large, which is the difference between the flue gas and the heat exchange component. The first heat exchange component provides sufficient space for heat exchange, so that the heat exchange is sufficient, and the heat generated by the air conditioning component is discharged through the flue, which can dissipate heat for the air conditioning component more efficiently and increase the cooling capacity of the air conditioning component by 10%. -15% for a cooler and more comfortable kitchen environment.

The smoke exhaust channel forms a first smoke exhaust channel 221 and a second smoke exhaust channel 222 through the bifurcation, and a switching valve 3 is provided at the bifurcation. By switching the switching valve 3, the first smoke exhaust channel 221 and the fan can be discharged The tuyere is communicated or the second smoke exhaust channel 222 is communicated with the air outlet of the fan. When the air valve is on the right side, the range hood works alone, and the air conditioning system does not start; the other is when the air valve is on the left side to achieve the effect of exhausting oil fume and air conditioning at the same time. In this way, when heating or cooling is not required, the heat exchange component can be free from oil fume pollution, which helps to improve its working life.

The compressor of the air conditioning component is integrated into the fume exhaust system, which makes it easier to realize the connection between the heat exchange component in the fume machine and the heat exchange component in the internal machine to form a cooling or heating pipeline, which makes the structure of the device more compact and facilitates the heat exchange component. and piping installation. The compressor is located in the fume exhaust system, and the sealing effect is good, which can reduce its noise caused by vibration.

In order to prevent oil fume from polluting the first heat exchanger 12, an oil fume purification device 4 is also installed in the first fume exhaust channel 22, and the oil fume purification device 4 is arranged at the front end of the first heat exchanger 12, and the oil fume exhaust system has a purification device. , The purification device can provide the oil separation degree of oil fume, filter the oil fume and then pass through the heat exchange device, which can greatly improve the working efficiency and working life of the heat exchange device. After filtering, the content of oil fume can be reduced by 80%. -90%, good for environmental protection.

When the air conditioner is started, the first smoke exhaust channel 22 is opened and the second smoke exhaust channel 23 is closed by switching the switching valve 3. Taking the air conditioner refrigeration mode as an example, the first heat exchanger 12 is a condenser, and the second heat exchange The evaporator 13 is an evaporator, and the fresh air entering from the air inlet 15 is cooled and then blown out from the fresh air outlet 16 to provide cold air for the kitchen. After the heat is taken away, it is discharged from the first smoke exhaust passage 221 , thereby improving the heat exchange effect of the first heat exchanger 12 , thereby facilitating the improvement of the energy efficiency of the air conditioner.

When the air conditioner stops working, the range hood is in the normal working mode. At this time, through the switching of the switching valve 3, the first smoke exhaust passage 22 is closed, the second smoke exhaust passage 23 is opened, and the flue gas discharged from the fan 21 enters the second smoke exhaust passage 23. The smoke exhaust channel 23 is also discharged.

An anti-smoke treasure is installed on the exhaust channel to ensure that the flue gas in the flue flows in one direction, avoiding the backflow of oil fume, and also preventing the bacteria and other pollutants left in the exhaust channel from flowing back to the kitchen.

Embodiment 2:

As shown in FIG. 2 , the air inlet passage 23 forms a first air inlet passage 231 and a second air inlet passage 232 through the bifurcated port, and a switching valve 3 is provided at the bifurcation port. The smoke exhaust channel 231 is communicated with the air outlet of the fan, or the second smoke exhaust channel 232 is communicated with the air outlet of the fan. When the air valve is on the right side, the range hood works alone, and the air conditioning system does not start; the other is when the air valve is on the left side to achieve the effect of exhausting oil fume and air conditioning at the same time. In this way, when heating or cooling is not required, the heat exchange component can be free from oil fume pollution, which helps to improve its working life.

Embodiment three:

As shown in FIG. 3 , the kitchen air conditioning system in this embodiment includes an air conditioning assembly 1 and a range hood 2 . The air conditioning assembly 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 communicated through a refrigerant pipeline 14. The working principle of the air conditioning assembly 1 is the same as that of the existing air conditioner, and will not be described here.
