Problems solved by technology

[0002] At present, with the improvement of people's living standards, the oil fume treatment devices used in the kitchen are generally range hoods with filtering and purification functions. The single-layer grille structure or the double-layer grille structure is mainly used to intercept oil fumes containing a large number of volatile particles. However, due to the high viscosity and high resistance of the oil fume particles, it will be difficult to clean after a period of use. Problems such as poor extraction of oil fume, and after using the above-mentioned net cover, some oil fume with volatile particles is still discharged outside during the interception process, causing pollution to the environment

Embodiment Construction

[0013] As shown in Fig. 1 and Fig. 2, the present invention comprises an outer roulette 1 and an inner roulette 2, the outer roulette 1 is circular, its outer peripheral surface is a toothed structure, the inner roulette 2 is a triangular shape, and the inner roulette 2 There are three grooves 5 substantially parallel to the triangular sides, and the side of the grooves 5 opposite to the outer wheel 1 is a tooth-shaped structure. The outer wheel 1 and the inner wheel 2 are connected together by supporting ribs 3. Between the outer wheel disc 1 and the inner wheel disc 2, a filter screen 7 composed of a filter screen wire 4 is provided. 1. The tooth shapes on 1 are formed by synchronous circumferential movement and winding. A shaft sleeve 6 connected with the output shaft of the motor is provided at the center of the inner wheel disc 2 . The diameter of the filter wires 4 is 0.1-0.5 mm, and the angle between adjacent filter wires 4 in the radial direction is 1.5-3.0 degrees. ...

Abstract

The invention discloses a rotary strainer disk used for a range hood, comprising an outer rotary table and an inner rotary table which are connected together through a support rod; a strainer formed by strainer-mesh is arranged between the inner rotary table and the outer rotary table. By adopting the structure, the invention is provided with reasonable design, convenient mounting and maintenance process and low manufacturing cost; the air resistance is small and the disposed air flow is big during running; the oil-smoke containing a plurality of volatile solids can be filtered and cleaned, and the filtering and cleaning efficiency generally can reach more than 90 percent.

Description

technical field [0001] The invention discloses a rotary filter disc used for a range hood, and belongs to the technical field of kitchen fume treatment equipment. Background technique [0002] At present, with the improvement of people's living standards, the oil fume treatment devices used in the kitchen are generally range hoods with filtering and purification functions. The single-layer grille structure or the double-layer grille structure is mainly used to intercept oil fumes containing a large number of volatile particles. However, due to the high viscosity and high resistance of the oil fume particles, it will be difficult to clean after a period of use. Problems such as poor oil fume extraction, and after the above-mentioned net cover is used, some oil fumes with volatile particles are still discharged outside during the interception process, causing pollution to the environment. Contents of the invention [0003] In order to solve the above problems, the object of...
