Figure 5 It is a partial structural front view of a smoke extractor 100 in one embodiment provided in the present application.

[0029] The smoke extractor 100 of the present application comprises a housing 10, a smoke extractor body 20, a temperature control device 30 and an exhaust device 40, wherein the smoke extractor body 20 and the temperature control device 30 are arranged in the housing 10. The temperature control device 30 comprises a compressor 31, an evaporator 32, a first fan 341, a condenser 33, a second fan 342, a first chamber 35 and a second chamber 36, and the exhaust device 40 comprises a first air inlet 41, a second air inlet 42 and an air outlet 43.

[0030] The following will introduce the technical details of each component one by one.

[0031] The housing 10 is the basic frame structure of the smoke extractor 100. The housing 10 can protect the smoke extractor body 20 and the temperature control device 30, reduce the risk of the smoke extractor body 20 and the temperature control device 30 being damaged by foreign objects, and also serve as a decorative effect to improve the appearance of the smoke extractor 100. The housing 10 can be made of metal and made by sheet metal technology, which is conducive to increasing the structural strength and rigidity of the housing 10 and reducing the risk of deformation or damage of the housing 10.

[0032] The range hood body 20 is the core component of the range hood 100. In the working state, the smoke in the room can be sucked through the smoke outlet 22 to purify the indoor air.

[0033] The temperature control device 30 has a cooling effect and outputs cold air through the cold air outlet 351 to reduce the indoor temperature.

[0034] The compressor 31 is a driven fluid machine that boosts low-pressure gas to high-pressure gas, and is the heart of the temperature control device 30. It sucks low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.

[0035] The evaporator 32 transfers heat to the refrigerant to evaporate it into gaseous state, thereby reducing the temperature of the surrounding air. The first fan 341 is used to guide the flow of cold air around the evaporator 32 so that the cold air is blown out from the cold air outlet 351.

[0036] The condenser 33 converts the evaporated gas into liquid by exchanging heat with the surrounding environment, and dissipates heat in the process. The second fan 342 is used to drive the hot air around the condenser 33 to flow so that the hot air is blown out from the hot air outlet 361.

[0037] The first chamber 35 is used to accommodate the evaporator 32 and the first fan 341 , and the second chamber 36 is used to accommodate the condenser 33 and the second fan 342 .

[0038] The first air inlet 41 is connected to the smoke outlet 23 of the range hood body 20 , the second air inlet 42 is connected to the hot air outlet 361 of the temperature control device 30 , and the air outlet 43 is used to guide smoke and hot air to be discharged.

[0039] In order to enable technical personnel in this field to have a further understanding of the technical field of this application, specific embodiments will be given below to explain the matching relationship of each component. The embodiments cannot be exhaustive. When technical solutions that can be pieced together based on the above-mentioned technical features without the need for creative labor by personnel in this field are all technical solutions protected by this application.

[0040] See also Figures 1 to 4 The present invention provides a range hood 100, which includes a range hood body 20, a temperature control device 30 and an exhaust device 40. The range hood body 20 is used to absorb oil smoke, 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. The exhaust device 40 is used to guide the hot air generated by the temperature control device 30 and the smoke sucked by the range hood body 20 to be discharged, thereby reducing the impact of hot air on the indoor temperature and improving the cooling effect of the temperature control device 30.

[0041] Specifically, the range hood body 20 includes a smoke inlet 22 and a smoke outlet 23 that are interconnected. The smoke inlet 22 is used to inhale smoke, and the smoke outlet 23 is used to exhaust smoke. The temperature control device includes a cold air outlet 351 and a hot air outlet 361. The cold air outlet 351 is used to output cold air to the room, and the hot air outlet 361 is used to output hot air. The exhaust device 40 includes a first air inlet 41, a second air inlet 42 and an air outlet 43. The first air inlet 41 is connected to the smoke outlet 23, the second air inlet 42 is connected to the hot air outlet 361, and the air outlet 43 is connected to the first air inlet 41 and the second air inlet 42. The air outlet 43 is used to exhaust smoke entering from the first air inlet 41 and hot air entering from the second air inlet 42.

[0042] By setting up the exhaust device 40, the first air inlet 41 is connected to the smoke outlet 23 of the range hood body 20, the second air inlet 42 is connected to the hot air outlet 361 of the temperature control device 30, and the air outlet 43 is connected to the first air inlet 41 and the second air inlet 42. The air outlet 43 guides the smoke entering from the first air inlet 41 and the hot air entering from the second air inlet 42 to be discharged, which is beneficial to reducing the influence of the hot air generated in the temperature control device 30 on the indoor temperature, thereby improving the cooling effect of the temperature control device 30.

[0043] In some embodiments, the range hood 100 further includes an outer shell 10, and the range hood body 20 and the temperature control device 30 are disposed inside 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, thereby improving the appearance of the range hood 100.

[0044] In some embodiments, the housing 10 is provided with a through hole 11, and the range hood body 20 includes a volute fan 21. When the volute fan 21 works, it can draw indoor smoke from the through hole 11 through the smoke extraction port 22 to discharge the indoor smoke.

[0045] The temperature control device 30 includes a compressor 31, an evaporator 32 and a condenser 33. 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, and this application will not repeat them.

[0046] 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, and the condenser 33 is disposed in the second chamber 36. Providing the evaporator 32 in the first chamber 35 and the condenser 33 in the second chamber 36 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.

[0047] Specifically, the cold air outlet 351 is connected to the first chamber 35 so that the cold air in the first chamber 35 can be discharged. The hot air outlet 361 is connected to the second chamber 36 so that the hot air in the second chamber 36 can be discharged.

[0048] In some embodiments, the smoke outlet 23 is located between the first chamber 35 and the second chamber 36 (eg, Figure 2 As shown), the first chamber 35 and the second chamber 36 are separated and isolated from each other, which is beneficial to further reduce the mutual thermal interference between the evaporator 32 and the condenser 33 and improve the refrigeration effect of the temperature control device 30.

[0049] In some embodiments, the exhaust device 40 is disposed in the outer shell 10 (not shown), and the outer shell 10 can protect and shield the exhaust device 40, reduce the risk of the exhaust device 40 being damaged by foreign objects, and reduce the impact of the exhaust device 40 on the appearance of the range hood 100, thereby improving the appearance of the range hood 100.

[0050] In some embodiments, the exhaust device 40 is disposed outside the housing 10 (not shown), which facilitates the exhaust device 40 to be connected to an exhaust passage in a building and facilitates the assembly of the smoke extractor 100 .

[0051] See also Figure 1 , Figure 4 and Figure 5 In some embodiments, the first air inlet 41 and the second air inlet 42 are disposed in the housing 10, and the air outlet 43 extends out of the housing 10. The housing 10 protects and shields the connection between the first air inlet 41 and the smoke outlet 23, and the connection between the second air inlet 42 and the hot air outlet 361, thereby reducing the risk of failure of the connection between the first air inlet 41 and the smoke outlet 23, and the connection between the second air inlet 42 and the hot air outlet 361 due to contact with foreign objects, and reducing the influence of the connection between the first air inlet 41 and the smoke outlet 23, and the connection between the second air inlet 42 and the hot air outlet 361 on the appearance of the smoke extractor 100, thereby improving the appearance of the smoke extractor 100.

[0052] In some embodiments, the angle between the flow direction of the smoke in the first air inlet 41 and the flow direction of the hot air in the second air inlet 42 is as small as possible, which is beneficial to reduce the mutual influence between the smoke fluid and the hot air fluid after entering the air outlet 43, and reduce the risk of poor exhaust on the other side due to excessive flow rate of one side.

[0053] In some embodiments, in the air outlet 43, the flow direction of the flue gas entering from the first air inlet 41 is parallel to the flow direction of the hot air entering from the second air inlet 42, which is beneficial to reduce the mutual influence between the flue gas fluid and the hot air fluid, and reduce the risk of poor exhaust on the other side due to excessive flow rate of one side.

[0054] In some embodiments, the exhaust device 40 is disposed above the range hood body 20 and the temperature control device 30 , which facilitates the exhaust device 40 to be connected to an exhaust passage in a building and facilitates the assembly of the range hood 100 .

[0055] See also Figures 1 to 4 In some embodiments, the temperature control device 30 also includes a first fan 341, which is disposed in the first chamber 35. The first fan 341 can guide the cold air around the evaporator 32 to flow toward the cold air outlet 351, which is beneficial to improving the cooling efficiency of the temperature control device 30.

[0056] In some embodiments, the first fan 341 is a volute fan 21, and the air outlet of the volute fan 21 faces the cold air outlet 351, so that the cold air in the first chamber 35 is blown out from the cold air outlet 351. The volute fan 21 is helpful to increase the air volume of the first fan 341 and improve the cooling effect of the temperature control device 30.

[0057] In some embodiments, the temperature control device 30 further includes a second fan 342 , which is disposed in the second chamber 36 . The second fan 342 can guide the hot air around the condenser 33 to flow toward the hot air outlet 361 when working.

[0058] In some embodiments, the second fan 342 is an axial flow fan. In some embodiments, the second fan 342 and the condenser 33 are arranged in a horizontal direction, so that the axial flow fan can blow air to the condenser 33.

[0059] In some embodiments, the hot air outlet 361 and the second fan 342 are located on both sides of the condenser 33 in the horizontal direction, which is conducive to the airflow generated by the operation of the second fan 342 to blow the hot air on the condenser 33 to the hot air outlet 361. At the same time, the airflow in the second chamber 36 passes through the condenser 33 in the horizontal direction, which is conducive to the heat dissipation of the condenser 33. In some embodiments, the airflow in the second chamber 36 flows toward the hot air outlet 361 under the action of the inner wall of the housing 10.

[0060] To summarize, in the range hood 100 provided by the present invention, an exhaust device 40 is provided, the first air inlet 41 is connected to the smoke outlet 23 of the range hood body 20, the second air inlet 42 is connected to the hot air outlet 361 of the temperature control device 30, and the air outlet 43 is connected to the first air inlet 41 and the second air inlet 42. The air outlet 43 guides the smoke entering from the first air inlet 41 and the hot air entering from the second air inlet 42 to be discharged, which is beneficial to reducing the influence of the hot air generated in the temperature control device 30 on the indoor temperature, thereby improving the cooling effect of the temperature control device 30.
