As shown in Figure 2, the refrigeration range hood system includes a range hood module, a compressor, a heat dissipation module and an internal module. The heat dissipation module and the internal module are arranged outside the range hood fan. The heat dissipation module includes a condenser and a heat dissipation fan.

The compressor, condenser and evaporator are connected through a refrigerant pipeline. The system arranges the heat dissipation fan inside the heat dissipation module. The wind dissipated by the condenser will continuously heat the inside of the heat dissipation module, thereby heating the heat dissipation motor, so that the temperature rise of the heat dissipation motor is increased, thereby affecting the performance of the heat dissipation motor. In order to solve the impact of the heat dissipation motor's temperature rise on performance, the heat dissipation motor is usually arranged outside the heat dissipation module housing, but the heat in the heat dissipation module will be transferred to the motor through the motor shaft. After working for a long time, the motor will still heat up, thereby reducing performance. The control board of the heat dissipation motor can also be arranged outside the heat dissipation module, but the heat in the heat dissipation module will affect the magnetic poles inside the motor, causing excessive temperature or even demagnetization, thereby affecting the motor performance. In summary, the existing refrigeration range hood system needs to be further improved.

DETAILED DESCRIPTION

The present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1 and 3, the refrigeration range hood system of this embodiment includes a casing 9, a fume extraction module 1, a compressor 2, a heat dissipation module 3 and an internal module 4. The fume extraction module 1, the compressor 2, the heat dissipation module 3 and the internal module 4 are all installed inside the casing 9, and the casing 9 is the outer shell of the range hood.

Specifically, the fume extraction module 1 includes an fume extraction fan 11, the heat dissipation module 3 and the indoor module 4 are arranged outside the fume extraction fan 11, the heat dissipation module 3 includes a condenser 31 and a heat dissipation fan 32, the indoor module 4 includes an evaporator 41 and an indoor fan 42, the compressor 2, the condenser 31 and the evaporator 41 are connected through a refrigerant pipeline 5, and a throttling device 6 is installed on the refrigerant pipeline 5 between the condenser 31 and the evaporator 41. An air-conditioning outlet is provided on the front of the casing 9, and an air outlet channel is provided inside the casing 9. The air outlet of the indoor fan 42 is connected to the air-conditioning outlet through the air outlet channel. In the cooling mode, the cold air blown by the indoor fan 42 is blown toward the cook through the air-conditioning outlet, thereby improving the user's cooking experience.

The heat dissipation module 3 has a heat dissipation cavity 33 and a motor installation cavity 34 which are isolated from each other. The condenser 31 and the fan blades 321 are installed in the heat dissipation cavity 33. The heat dissipation fan 32 has the fan blades 321 and a heat dissipation motor 322 which drives the fan blades 321 to rotate. The heat dissipation motor 322 is installed in the motor installation cavity 34. The air outlet of the heat dissipation fan 32 can be directly connected to the outside of the range hood, or can be fluidly connected to the inside of the volute of the range hood fan 11 through the air inlet on the volute ring wall, or can be fluidly connected to the air inlet of the range hood fan 11 through the air inlet on the fan frame.

In this embodiment, a three-way valve 7 is installed on the refrigerant pipeline between the compressor 2 and the evaporator 41. The inlet of the three-way valve 7 is connected to the outlet of the evaporator 41. The first outlet of the three-way valve 7 is connected to the inlet of the compressor 2 through the first refrigerant pipeline 51, and the second outlet of the three-way valve 7 is connected to the inlet of the compressor 2 through the second refrigerant pipeline 52. The second refrigerant pipeline 52 has a heat exchange section 521 arranged on the outer wall of the motor installation cavity 34. In order to improve the heat exchange efficiency, the heat exchange section 521 is attached to and arranged on the outer wall of the motor installation cavity 34. The heat exchange section 521 exchanges heat with the heat dissipation motor 322 in the motor installation cavity 34. Since the temperature of the refrigerant flowing through the heat exchange section 521 is relatively low, the outer wall of the motor installation cavity 34 can be cooled, thereby reducing the temperature of the heat dissipation motor 32.

In addition, a temperature sensor 8 is installed in the motor mounting cavity 34. The temperature sensor 8 is installed on the motor mounting cavity 34 and is used to detect the temperature of the heat dissipation motor 322. The controller (not shown in the figure) receives the output signal of the temperature sensor 8, and can control the switching action of the three-way valve 7 accordingly according to the received signal, adjust the flow of the first refrigerant pipeline 51 and the second refrigerant pipeline 52, and control the temperature of the heat dissipation motor 322 and the motor mounting cavity 34 within the required temperature range.

When the temperature of the heat dissipation motor 322 rises too high, the flow rate of the second refrigerant pipeline 52 can be increased, and the residual cold in the suction pipe of the refrigeration system can be used to cool the motor installation cavity 34, thereby improving the cooling effect of the motor and avoiding excessive temperature rise of the heat dissipation motor 322 and affecting the reliability of the system; when the temperature of the heat dissipation motor 322 is lower than the ambient temperature, condensation water may be generated on the surface of the motor installation cavity 34. At this time, the flow rate of the second refrigerant pipeline 52 needs to be reduced to prevent condensation water from being generated on the surface of the motor installation cavity 34 due to the low temperature.
