Problems solved by technology

[0003] Existing range hood filters generally have a single-layer or double-layer structure, and the method of filtering and intercepting grease is relatively simple, and most of them are ordinary plane collision condensation methods; the grease interception efficiency of the oil screen is not high, resulting in a large amount of oil fume entering Part of the hood cavity and inside the fan accumulates into oil and grease, which is easy to breed bacteria, produce odor and affect the performance of the hood; the other part of the fume is discharged outside and becomes a source of air pollution

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1 to Figure 3 As shown, a filter screen structure for range hoods includes a first layer of filter screen 1, a second layer of filter screen 2 and a third layer of filter screen 3 arranged in sequence, the first layer of filter screen 1 and the third layer of filter screen The filter screen 3 is a sheet metal screen with through holes, and the second filter screen 2 includes a filter sponge 22 .

[0027] The first layer of filter screen plays the role of the first oil fume blocking and interception, and pre-treats the oil fume;

[0028] The second layer of filter has good air flow characteristics, low wind resistance and strong adsorption capacity, not only has little effect on air volume and wind pressure, but also fully absorbs the grease in the oil fume, which greatly improves the oil interception efficiency of the filter; I...

Abstract

The invention discloses an extractor hood filter net and an extractor hood. The extractor hood filter net comprises a first-layer filter net, a second-layer filter net and a third-layer filter net which are sequentially arranged. The first-layer filter net and the third-layer filter net are sheet metal nets with through holes. The second-layer filter net comprises filter sponge. The grease stop efficiency can reach 60% or above and is improved by one time or above compared with 30% of a common oil net, the phenomenon that lampblack enters an extractor hood cavity or a fan to accumulate oil contamination and oil dirt is effectively reduced, and meanwhile lampblack exhausted outdoors is reduced.

Description

【Technical field】 [0001] The invention relates to a filter screen structure of a range hood, and the invention relates to a range hood. 【Background technique】 [0002] With the progress of the times and the development of society, people's demand for food diversification is getting higher and higher, and kitchen appliances are also showing a trend of integration. [0003] Existing range hood filters generally have a single-layer or double-layer structure, and the method of filtering and intercepting grease is relatively simple, and most of them are ordinary plane collision condensation methods; the grease interception efficiency of the oil screen is not high, resulting in a large amount of oil fume entering Part of the hood cavity and inside the fan accumulates into oil and grease, which is easy to breed bacteria, produce odors and affect the performance of the hood; the other part of the fume is discharged outside and becomes a source of air pollution. 【Content of inventi...
