Problems solved by technology

However, in actual use, it is found that for the first structure, although the required cleaning period is longer than that of the early fine mesh filter structure, oil stains are still easy to remain on the filter, resulting in increased wind resistance and The reduction of the air volume of the fan will affect the performance of the range hood; for the second structure, it has significantly improved the problem of oil residue, but there are still problems.

Embodiment 1

[0026] Such as Figure 1 ~ Figure 4 As shown, the range hood in this embodiment is not easy to leave oil stains on the filter device, including a fan body 1, a decorative shell 8 covering the outside of the body, and a smoke collecting hood 2 located directly below the body 1 and perpendicular to it. There is a fan volute 3, and the impeller and the motor driving the impeller are installed in the volute 3 (the impeller and the motor are not shown in the figure), and the smoke collecting hood 2 is provided with an air inlet 21 that is convenient for the oil fume to enter the inner cavity of the volute 3. The bottom of the air inlet 21 is provided with an oil deflector 4 with a predetermined distance from the end face of the air inlet of the fume collecting hood 2 , and an oil fume filter device in the shape of a small upper part and a larger bottom is arranged between the air inlet 21 and the oil guide plate 4 .

[0027] The oil fume filtering device includes a filter screen fr...

Embodiment 2

[0030] Such as Figure 5 As shown, the present embodiment is basically the same as the first embodiment, the only difference being that the oil fume filtering device is a frustum-shaped filter screen 8 with sufficient rigidity.

Embodiment

[0032] Such as Figure 6 As shown, the present embodiment is basically the same as the first embodiment, the only difference being that the oil fume filtering device is a combined filter screen in the shape of a sloping roof formed by butting two filter screens 9 .

Abstract

The invention discloses a range hood unsusceptible to residing oil stain on a filter device, which comprises a fan body and a fume collecting hood arranged below the fan body. The fume hood is provided with an air inlet which is provided with an oil fume filter device. The range hood is characterized in that an oil deflector which reserves a preset distance with the end face of the air inlet of the fume collecting hood is arranged below the air inlet; the oil fume filter device is arranged between the air inlet and the oil deflector; and the oil fume filter device is of a shape with a large upper part and a small lower part. A filter screen is insusceptibility to oil accumulation, thereby enlarging the area of wind field, improving the oil fume adsorption effect, effectively reducing noise of entire machine and achieving core filtering and low emission. The range hood is particularly suitable for a household range hood.

Description

technical field [0001] The invention relates to a range hood in household kitchen appliances, in particular to a range hood with small wind resistance and low noise. Background technique [0002] The range hood is one of the essential kitchen appliances in the family. Among them, European-style range hoods are widely favored by consumers because of their neat and beautiful appearance and small footprint. Existing European-style range hoods generally include a fan body (inlet box) and a smoke collecting hood positioned below the body and perpendicular to it in structure. The motor and the fume collecting hood are provided with an air inlet to facilitate the oil fume to enter the inner cavity of the volute. In order to prevent the oil fume from entering the range hood and pollute the inner cavity of the body or the inner cavity of the volute and the impeller, and also to prevent the oil fume from being discharged into the atmosphere and affecting the environment, the existin...
