Problems solved by technology

The noise reduction cotton will be saturated after accumulating oil for a long time, and the oil will leak outward. In severe cases, the oil droplets will even flow down along the chassis and outer cover
In addition, the noise reduction cotton will reduce the sound absorption effect after absorbing the oil, which will lead to the technical problem of increased noise after the range hood is used for a long time

Embodiment 1

[0034] Such as figure 1 As shown, the anti-seepage oil noise reduction assembly provided by the embodiment of the present invention includes: a perforated part 100, a noise reduction box 200, and a sound-absorbing part 300; box 200 , and there is a gap between the punching part 100 and the sound-absorbing part 300 .

[0035] Specifically, the sound-absorbing member 300 may use noise-reducing cotton, the noise-reducing box 200 may be an integrally formed part, and the noise-reducing cotton is installed in the inner cavity of the noise-reducing box 200 . The anti-seepage oil noise reduction component can be used to reduce the noise of the range hood. There is a gap between the perforated part 100 and the sound-absorbing part 300, which can reduce the probability of the oil passing through the perforated part 100 contacting the sound-absorbing part 300, thereby reducing the absorption of the sound-absorbing part 300. The amount of oil should be reduced to prevent the sound-absor...

Embodiment 2

[0056] Such as figure 1 with Figure 8 As shown, the range hood provided by the embodiment of the present invention includes: a chassis 500, a fan assembly 600 and the anti-seepage oil noise reduction assembly provided in Embodiment 1; the fan assembly 600 is installed in the chassis 500, and the noise reduction box 200 is installed in the chassis The side opening of 500, the sound absorbing part 300 is located between the sound absorbing part 300 and the fan assembly 600.

[0057] Specifically, the noise reduction box 200 is provided with a convex hull 203, and the convex hull 203 is clamped on the side wall of the chassis 500. The noise reduction box 200 is flush with the outer surface of the side wall of the chassis 500, so that the outer cover can be installed more smoothly. Oil smoke can pass through the perforated part 100 and enter the gap between the perforated part 100 and the sound-absorbing part 300, and the oil can flow down along the perforated part 100, and fina...

Abstract

The invention provides an oil seepage prevention and noise reduction assembly and a range hood, and relates to the technical field of range hoods. The oil seepage prevention and noise reduction assembly comprises a perforated part, a noise reduction box and a sound absorption part, wherein the sound absorption part is installed in the noise reduction box, the perforated part covers the noise reduction box, and a gap is formed between the perforated part and the sound absorption part; a plurality of concave-convex end faces are arranged on the side, facing the perforated part, of the sound absorption part, and cavities are formed between the perforated part and the concave-convex end faces correspondingly. According to the oil seepage prevention and noise reduction assembly, contact betweenoil and the sound absorption part can be reduced, and then the sound absorption part can keep a good sound absorption effect for a long time.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to an anti-seepage oil noise reduction component and a range hood. Background technique [0002] In order to reduce the noise of the range hood, noise reduction components are installed on both sides of the chassis, and the noise reduction components absorb noise through the internal noise reduction cotton, thereby reducing the operating noise of the range hood. The noise reduction cotton will be saturated after accumulating oil for a long time, and the oil will leak outward. In severe cases, the oil droplets will even flow down along the chassis and the outer cover. In addition, after the noise-reducing cotton absorbs the oil, the sound-absorbing effect will be reduced, which will lead to the technical problem of increased noise after the range hood is used for a long time. Contents of the invention [0003] The object of the present invention is to provide an anti-seepage o...
