[0080] This embodiment provides a range hood, such as figure 1 As shown, the range hood includes a fan system, the fan system includes a volute 1 and an impeller 2, the impeller 2 is located in the inner cavity (not shown) of the volute 1, and when the range hood smokes the range hood, the impeller 2 rotates, A negative pressure is formed above the stove, and the fume gas in the room is sucked into the inner cavity of the volute 1 .

[0081] The blower system also includes an automatic cleaning device, which is used for cleaning oil stains on the range hood automatically rather than manually. The automatic cleaning device includes a heating pipe 3 for gas to pass through, and the heating pipe 3 can melt the oil stain on the part to be cleaned by heating at least one oily part to be cleaned on the range hood, and then flow into the oil collection of the range hood In the device, so as to achieve the function of automatic cleaning. It should be noted that, in the technical sol...

[0113] The difference between the second embodiment and the first embodiment lies in the arrangement of the heating tubes on the volute. In the second embodiment, as Figure 6 As shown, the heating pipe 3 located on the shroud 13 includes a first section of pipe 32 extending along the circumference of the volute 1, and at least two second sections of pipe 33 extending along the axial direction of the volute 1, each of the first sections The two-section tubes 33 are sequentially arranged along the circumferential direction of the volute 1, and two adjacent second-section tubes 33 are connected at one of their ends close to each other, and one end of the first-section tube 32 is connected to one of the second-section tubes. 33 are connected at one end, and the inlet 31 of the heating pipe 3 is arranged on the first section of pipe 32 . By arranging the heating pipe 3 extending in a winding manner on the outer wall of the enclosure 13, the length of the heating pipe 3 can be inc...

[0116] The difference between the third embodiment and the first embodiment is that in the third embodiment, if Figure 7 As shown, an opening (not shown) is provided on the surrounding plate 13 close to the air outlet 10 of the volute 1, and the opening is located on the rear side of the surrounding plate 13. The so-called rear side refers to the front and rear direction X of the range hood. on the side facing away from the user. The outlet 30 of the heating pipe 3 leads to this opening, so that the hot gas discharged from the outlet 30 can be sent into the inner cavity of the volute 1 .

Abstract

The invention discloses a smoke exhaust ventilator and a fan system thereof. The smoke exhaust ventilator comprises an automatic cleaning device which comprises a heating tube (3) for allowing gas topass through, the heating tube (3) is used for heating at least one part, with oil dirt needing to be removed, of the smoke exhaust ventilator, and an outlet (30) of the heating tube (3) is used for leading to the interior of the smoke exhaust ventilator so that heat of hot gas exhausted from the outlet (30) is transmitted to the at least one part, with oil dirt needing to be removed, of the smokeexhaust ventilator. According to the smoke exhaust ventilator and the fan system thereof, various functions are integrated on the heating tube, the part with oil dirt needing to be removed can be heated through heat transmission of the heating tube and the hot gas exhausted from the outlet of the heating tube, so that the oil dirt on the part with oil dirt needing to be removed can be more sufficiently melted and flows into an oil collecting device of the smoke exhaust ventilator, and the automatic cleaning effect is improved accordingly.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood and a fan system thereof. Background technique [0002] The range hood is a kind of kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove. It can quickly take away the waste burned by the stove and the harmful oil fume generated during the cooking process, and discharge it outdoors to reduce pollution and purify the indoor air. . During the use of the range hood, grease is most likely to adhere to the range hood. If it is not cleaned effectively for a long time, the grease will accumulate more and more, and the grease will be difficult to clean due to oxidation and air drying. [0003] For this reason, the prior art proposes many automatic cleaning methods for the range hood to clean the inside of the range hood. However, all of them have the problem of poor automatic cleaning effect. Contents of the invention...
