[0032] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] Range hoods, as a common kitchen appliance, are widely used in kitchens. A range hood consists of a main body and a fan housed within it. When the fan is working, it quickly draws away the cooking fumes and exhausts them outdoors. During operation, grease and grime adhere to the inside of the range hood. Over time, this can cause grease and grime to drip from the internal walls onto the stovetop or clog the grease filter, thus affecting the range hood's performance. Therefore, regular cleaning of the range hood's internal components is necessary. The fan itself includes a housing and an impeller inside. Grease and grime also accumulate on the housing and impeller; therefore, cleaning the inside of the range hood also includes cleaning the fan.

[0034] Currently, the main cleaning solution for fans is a steam-detergent mixture. Both steam and detergent are delivered via pumps, resulting in complex structures and high installation costs. Furthermore, this method can only clean the fan impeller, limiting the cleaning scope and leaving room for improvement.

[0035] To address the aforementioned technical problems, this application provides a fan assembly and a range hood. When cleaning the fan of this range hood, at most one pump body is needed to deliver and mix steam and detergent, simplifying the structure and reducing installation costs. Furthermore, it can also clean the fan casing, increasing the cleaning range. The specific structure of the range hood is now further described with reference to the accompanying drawings.

[0036] Figure 1 The present application shows a schematic diagram of the structure of a range hood 10 according to one or more embodiments. Figure 1 The range hood 10 includes a body 100 and a fan assembly. The fan assembly is disposed within the body 100 and includes a fan 200. The fan 200 is disposed within the body 100 and includes a housing 201 and an impeller 202. The housing 201 has an air inlet side 203, and the air inlet side 203 of the housing 201 is provided with an air inlet 204. When the range hood 10 is running, the impeller 202 of the fan 200 is activated, and airflow is introduced into the housing 201 through the inlet and led out of the housing 201 to quickly remove and exhaust the cooking fumes generated by the user outdoors.

[0037] Figure 2 A schematic diagram of the wind turbine assembly is shown. (Combined with...) Figure 2 The fan assembly also includes a spray pipe 300, which is disposed inside the body 100. The spray pipe 300 has a communicating first inlet 301, a second inlet 302, and a water outlet 303. The water outlet 303 is disposed near the air inlet 204 of the fan 200. The first inlet 301 is used to supply steam to the spray pipe 300, the second inlet 302 is used to draw detergent into the spray pipe 300, the spray pipe 300 is used to mix steam and detergent to form a cleaning solution, and the water outlet 303 is used to spray the cleaning solution toward the fan 200 to clean the fan 200.

[0038] When cleaning the fan 200 of the range hood 10 provided in this application, steam is injected into the spray pipe 300 through the first inlet 301, which can generate negative pressure in the spray pipe 300, thereby drawing detergent into the spray pipe 300 through the second inlet 302. This eliminates the need for a pump to deliver detergent, simplifying the structure and reducing installation costs. The cleaning solution formed by the mixture of steam and detergent in the spray pipe 300 is sprayed out from the water outlet 303 to clean the fan 200, ensuring a good cleaning effect on the fan 200.

[0039] Figure 3 It shows Figure 2 A structural diagram from another perspective. Combined with... Figure 2 as well as Figure 3The spray pipe 300 of this application includes a first pipe body 304 and a second pipe body 305. The first pipe body 304 is the main pipe, with one end being a first inlet 301 and the other end being a water outlet 303. The second pipe body 305 is a branch pipe, with one end being a second inlet 302 and the other end connected to the periphery of the first pipe body 304. When steam is delivered into the first pipe body 304 through the first inlet 301 and sprayed from the water outlet 303, a negative pressure is generated within the first pipe body 304. This allows detergent from the washing box to be drawn into the second pipe body 305 through the second inlet 302 and then back into the first pipe body 304. The steam and detergent mix within the first pipe body 304 and are then sprayed out from the water outlet 303 to clean the fan 200.

[0040] In specific implementation, the first pipe body 304 and the second pipe body 305 of the spray pipe 300 can be constructed separately, such as the first spray pipe 300a described below. The first pipe body 304 and the second pipe body 305 of the spray pipe 300 can be constructed integrally, such as the second spray pipe 300b described below. This application does not limit this.

[0041] Combination Figure 2 as well as Figure 3 There are two spray pipes 300. For ease of description, the two spray pipes 300 are referred to as the first spray pipe 300a and the second spray pipe 300b. The first spray pipe 300a is used to clean the inside of the impeller 202, and the second spray pipe 300b is used to clean the area between the outside of the impeller 202 and the housing 201. In addition, the second spray pipe 300b can also clean the outer surface of the housing 201.

[0042] Combination Figure 2 as well as Figure 3 The water outlet 303 of the first spray pipe 300a is inserted into the housing 201 through the air inlet 204 and is located inside the impeller 202 to clean the inside of the impeller 202. The water outlet 303 of the first spray pipe 300a can be arranged parallel to or nearly parallel to the axial direction of the fan 200 to a certain extent to avoid the water outlet 303 of the first spray pipe 300a obstructing or disturbing the airflow.

[0043] Combination Figure 2 as well as Figure 3In order to improve the cleaning effect on the inner circumferential surface of the impeller 202, the water outlet 303 of the first spray pipe 300a can face the inner circumferential surface of the impeller 202. The end and circumferential surface of the water outlet 303 of the first spray pipe 300a are provided with first spray holes 306 to ensure that the cleaning solution sprayed by the first spray holes 306 of the water outlet 303 of the first spray pipe 300a can be sprayed onto the inner circumferential surface of the impeller 202, thus ensuring the cleaning effect on the inner circumferential surface of the impeller 202. It should be noted that the first spray hole 306 located on the circumference of the water outlet end 303 of the first spray pipe 300a is preferably set on different sides of the circumference of the water outlet end 303 of the first spray pipe 300a. For example, the first spray hole 306 is provided on both opposite sides of the circumference of the water outlet end 303 of the first spray pipe 300a, so as to ensure the coverage of the cleaning solution sprayed by the first spray hole 306 inside the impeller 202 and ensure the cleaning effect on the inside of the impeller 202.

[0044] Combination Figure 2 as well as Figure 3 The water outlet 303 of the second spray pipe 300b is inserted into the housing 201 from the air inlet side 203 and is located between the impeller 202 and the housing 201. The direction of the water outlet 303 of the second spray pipe 300b can also be parallel or nearly parallel to the axial direction of the fan 200. The water outlet 303 of the second spray pipe 300b is provided with a second spray hole 307. The cleaning solution sprayed by the second spray hole 307 can be sprayed onto the outer peripheral surface of the impeller 202 and the inner wall of the housing 201, thereby ensuring the cleaning effect on the outer peripheral surface of the impeller 202 and the inner wall of the housing 201.

[0045] Combination Figure 2 as well as Figure 3 Multiple second spray holes 307 are disposed on different sides of the circumferential surface of the outlet end 303 of the second spray pipe 300b. For example, second spray holes 307 are disposed on opposite sides of the circumferential surface of the outlet end 303 of the second spray pipe 300b. The cleaning solution sprayed by the second spray holes 307 on the side of the circumferential surface of the outlet end 303 of the second spray pipe 300b facing the impeller 202 is mainly sprayed onto the outer circumferential surface of the impeller 202 to ensure the cleaning effect on the outer circumferential surface of the impeller 202. The cleaning solution sprayed by the second spray holes 307 on the side of the circumferential surface of the outlet end 303 of the second spray pipe 300b facing the impeller 202 is mainly sprayed onto the inner circumferential surface of the housing 201 to ensure the coverage of the cleaning solution sprayed by the second spray holes 307 inside the housing 201 and to ensure the cleaning effect inside the housing 201.

[0046] Combination Figure 2 as well as Figure 3The water outlet 303 of the second spray pipe 300b also has a water outlet portion 3031 located outside the housing 201. The water outlet portion 3031 is also provided with a second spray hole 307. The cleaning solution sprayed by the second spray hole 307 on the water outlet portion 3031 can be sprayed to the air inlet side 203 of the housing 201 to clean the air inlet side 203 of the housing 201.

[0047] Figure 4 A schematic diagram of a water circuit for a range hood 10 is shown. (Combined with...) Figure 4 In one embodiment, the range hood 10 further includes a clean water box 400, a heating element 500, and a pump body 600. The clean water box 400 stores clean water. The heating element 500 can be a steam generator. The pump body 600 is disposed between the clean water box 400 and the heating element 500. The pump body 600 connects the clean water box 400 and the heating element 500. The heating element 500 is connected to the first inlet 301 of the spray pipe 300. The clean water in the clean water box 400 is transported to the heating element 500 through the pump body 600. After being heated by the heating element 500, it forms steam. The steam is transported to the spray pipe 300 through the first inlet 301 and sprayed from the water outlet 303 of the spray pipe 300.

[0048] Combination Figure 4 The range hood 10 also includes a washing box 700, which stores detergent. The washing box 700 is connected to the second inlet 302 of the spray pipe 300. When steam is injected into the spray pipe 300 through the first inlet 301, a negative pressure is generated within the spray pipe 300, thereby drawing the detergent from the washing box 700 into the spray pipe 300 through the second inlet 302. The steam and detergent mix within the spray pipe 300 to form a cleaning solution, which is then sprayed out from the outlet 303 to clean the fan 200. This solution requires only one pump body 600 to mix the steam and detergent within the spray pipe 300, thus simplifying the structure and reducing costs.

[0049] Figure 5 Another water circuit diagram of the range hood 10 is shown. Combined with... Figure 5In another embodiment, the pump body 600 connecting the clean water box 400 and the heating element 500 can be eliminated. There is a height difference between the clean water box 400 and the heating element 500. Clean water in the clean water box 400 is transported to the heating element 500 under gravity, where it is heated to form steam. The steam is then transported to the spray pipe 300 through the first inlet 301 and sprayed from the outlet 303 of the spray pipe 300. Simultaneously, a negative pressure is generated within the spray pipe 300, drawing detergent from the washing box 700 into the spray pipe 300 through the second inlet 302. The steam and detergent mix within the spray pipe 300 to form a cleaning solution, which is then sprayed out from the outlet 303 to clean the blower 200. This solution eliminates the need for the pump body 600 and allows for mixing of steam and detergent within the spray pipe 300, thus simplifying the structure and reducing costs.

[0050] The fan assembly and range hood 10 with the fan assembly provided in this application, when cleaning the fan 200, utilize the steam and detergent contained in the cleaning solution. The steam softens the grease adsorbed by the fan 200, and the detergent decomposes the grease on the fan 200. To ensure the effectiveness of cleaning the fan 200, the impeller 202 can be temporarily kept stationary during the cleaning process. The cleaning solution is sprayed out, covering most of the impeller 202 and the housing 201, and then the impeller 202 is started to rotate continuously or intermittently to achieve the effect of circulating the cleaning solution, thereby improving the cleaning effect on the fan 200.
