[0031] See also Figures 1 to 4 The present invention provides a range hood 100, which includes a range hood body 20 and a temperature control device 30. The range hood body 20 is used to extract oil smoke, and the temperature control device 30 is used to output cold air to reduce the indoor temperature, which is beneficial to improving the comfort of indoor personnel.

[0032] The temperature control device 30 includes a compressor 31, an evaporator 32, a condenser 33 and a heat dissipation component 34. The compressor 31, the evaporator 32 and the condenser 33 cooperate to make the temperature control device 30 have a refrigeration effect. The working principles of the compressor 31, the evaporator 32 and the condenser 33 are conventional technical means in the field of air conditioning technology, and this application will not repeat them.

[0033] The heat dissipation assembly 34 includes a flow guide 341 , a water collecting tank 342 , a water pump 343 and a fan 344 .

[0034] The water collecting tank 342 is arranged below the condenser 33, a portion of the flow guide 341 is located below the evaporator 32, a portion of the flow guide 341 is connected to the water collecting tank 342, and the flow guide 341 is configured to guide the condensed water generated by the evaporator 32 to the water collecting tank 342, so that the condensed water accumulates in the water collecting tank 342. During the operation of the compressor 31 and the evaporator 32, the evaporator 32 will generate a large amount of condensed water, which can flow through the flow guide 341 to the water collecting tank 342 below the condenser 33 and accumulate in the water collecting tank 342.

[0035] Part of the water pump 343 is located in the water collecting tank 342. The water pump 343 is configured to transport the condensed water in the water collecting tank 342 to the surface of the condenser 33, and evaporate the condensed water through the heat of the condenser 33 itself. This is not only beneficial to reduce the accumulation of condensed water in the range hood 100, but also beneficial to cool the condenser 33.

[0036] The fan 344 is configured to blow air toward the condenser 33. The blowing of the fan 344 can blow away the heat on the condenser 33 and the steam generated by the evaporated condensed water, which is further beneficial to the heat dissipation of the condenser 33. In addition, by controlling the blowing direction of the fan 344, the flow direction of the heat and water vapor can also be adjusted, thereby reducing the influence of the heat and water vapor emitted by the condenser 33 on the range hood 100 or the indoor temperature.

[0037] The range hood 100 also includes an outer shell 10, and the range hood body 20 and the temperature control device 30 are arranged in the outer shell 10. The outer shell 10 protects the range hood body 20 and the temperature control device 30, which helps to reduce the risk of the range hood body 20 and the temperature control device 30 being damaged by foreign objects. The outer shell 10 also serves a decorative purpose to improve the appearance of the range hood 100.

[0038] In some embodiments, the housing 10 includes a smoke extraction port 11 , and the range hood body 20 includes a volute fan 21 . The volute fan 21 can extract air from the smoke extraction port 11 to discharge indoor smoke.

[0039] In some real-time methods, the water pump 343 includes a pumping pipe 3431, one end of which is located in the water collecting tank 342, and the other end of the pumping pipe 3431 is arranged on the condenser 33. The water pump 343 transports the condensed water in the water collecting tank 342 to the surface of the condenser 33 through the pumping pipe 3431.

[0040] In some embodiments, the condenser 33 includes a first side surface 331 and a second side surface 332 which are opposite to each other, the first side surface 331 and the fan 344 face each other, the second side surface 332 is located on the side of the condenser 33 which is opposite to the fan 344, and the fan 344 blows air toward the first side surface 331, so that the airflow sequentially passes through the first side surface 331 and the second side surface 332. The water pump 343 is configured to transport the condensed water in the water collecting tank 342 to the first side surface 331, part of the condensed water is evaporated by the first side surface 331, and part of the condensed water flows downward along the first side surface 331, and during the flow process, the gas flow caused by the operation of the fan 344 can blow part of the condensed water from the first side surface 331 to the second side surface 332, so that part of the condensed water is further evaporated, thereby increasing the evaporation amount of the condensed water by the condenser 33 and improving the cooling effect of the condenser 33.

[0041] Furthermore, the water pump 343 is configured to transport the condensed water in the water collection tank 342 to the upper part of the first side 331, so that part of the condensed water flows downward from the upper part of the condenser 33, which is beneficial to increase the contact area between the condensed water and the condenser 33, increase the evaporation amount of the condensed water by the condenser 33, further reduce the accumulation of condensed water in the range hood 100, and further improve the cooling effect of the condenser 33.

[0042] See also Figure 5 In some embodiments, the water pump 343 is configured to transport the condensed water in the water collection tank 342 to the upper surface of the condenser 33, so that the condensed water flows from the condenser 33 from top to bottom under the action of gravity, which is beneficial to increase the contact area between the condensed water and the condenser 33, increase the evaporation amount of the condensed water by the condenser 33, further reduce the accumulation of condensed water in the range hood 100, and further improve the cooling effect of the condenser 33.

[0043] Specifically, the water outlet end of the water pumping pipe 3431 is arranged on the upper surface of the condenser 33 , so that the condensed water is transported from the water collecting tank 342 to the upper surface of the condenser 33 .

[0044] In some embodiments, the water pump 343 is also configured to atomize the condensed water and transport the atomized condensed water to between the condenser 33 and the fan 344 (not shown). The fan 344 drives the gas flow by rotating the fan blades. The airflow blows the atomized condensed water to the condenser 33. The heat dissipated by the condenser 33 evaporates the atomized condensed water. Compared with the condensed water in liquid state, the condensed water in atomized state is easier to evaporate, which is beneficial to increase the evaporation amount of condensed water by the condenser 33, further reduce the accumulation of condensed water in the range hood 100, and further improve the cooling effect of the condenser 33.

[0045] In some embodiments, the water pump 343 is also configured to atomize the condensed water and transport the atomized condensed water to the first side 331 (not shown) of the condenser 33. The fan 344 drives the gas flow by rotating the fan blades. The airflow blows part of the atomized condensed water that has not been evaporated by the first side 331 to the second side 332, which is beneficial to increase the evaporation amount of condensed water by the condenser 33, further reduce the accumulation of condensed water in the range hood 100, and further improve the cooling effect of the condenser 33.

[0046] See also Figure 2 and Figure 3 In some embodiments, the guide member 341 includes a water guide groove 3411, which is arranged to be inclined downward from the evaporator 32 toward the water collecting groove 342. The condensed water generated on the evaporator 32 may directly drip onto the water guide groove 3411 under the action of gravity, and flow to the water collecting groove 342 under the guidance of the water guide groove 3411 to accumulate in the water collecting groove 342.

[0047] See also Figure 6In some embodiments, the flow guide 341 includes a water guide pipe 3412, a first port of the water guide pipe 3412 is connected to the evaporator 32, a second port of the water guide pipe 3412 extends to the water collecting tank 342, the first port is connected to the second port, and the first port is higher than the second port. The first port of the water guide pipe 3412 collects condensed water generated on the evaporator 32, and under the action of gravity, the condensed water flows from the first port to the second port to accumulate in the water collecting tank 342.

[0048] See also Figure 7 In some embodiments, the fan 344 and the condenser 33 are arranged in a horizontal direction, and the wind blown by the fan 344 blows directly toward the first side surface 331 of the condenser 33 .

[0049] In one embodiment, the fan 344 is a centrifugal fan 344 , which is helpful to optimize the layout inside the smoke extractor 100 , increase the air volume of the fan 344 , and improve the heat dissipation effect of the condenser 33 .

[0050] In one embodiment, the fan 344 is an axial flow fan 344 , which helps to reduce the outer size of the fan 344 , reduce the impact of the volume of the fan 344 on the range hood 100 , and improve the space utilization rate in the range hood 100 .

[0051] See also Figure 2 and Figure 3 In some embodiments, the temperature control device 30 further includes a first chamber 35 and a second chamber 36. The evaporator 32 is disposed in the first chamber 35, the water collecting tank 342, the condenser 33 and the fan 344 are disposed in the second chamber 36, a portion of the guide member 341 is disposed in the first chamber 35, and a portion of the guide member 341 is disposed in the second chamber 36. The evaporator 32 is disposed in the first chamber 35 and the condenser 33 is disposed in the second chamber 36, which is conducive to reducing the mutual thermal interference between the evaporator 32 and the condenser 33 and improving the refrigeration effect of the temperature control device 30.

[0052] In some embodiments, the first chamber 35 is higher than the second chamber 36 , which facilitates the condensed water generated by the evaporator 32 to flow into the sump 342 of the second chamber 36 , thereby reducing the risk of condensed water accumulating in the first chamber 35 .

[0053] To sum up, in the range hood 100 provided by the present invention, a heat dissipation component 34 is arranged in the temperature control device 30, the water collecting tank 342 is used to collect condensed water, and the water pump 343 is used to sprinkle the condensed water onto the surface of the condenser 33. The condensed water is evaporated by the heat of the condenser 33 itself, which is not only beneficial to reduce the accumulation of condensed water in the range hood 100, but also beneficial to cool the condenser 33. At the same time, the fan 344 blows air to the condenser 33, which is further beneficial to the heat dissipation of the condenser 33.
