Embodiment 1

[0020] The present invention is a structure of oil fume filter plate as shown in Figure 1 and Figure 2: it is mainly composed of front cover plate 1, rear wing plate 6, oil filter screen 2 and rear cover plate 3, wherein the oil filter screen 2 is clamped in the front Between the cover plate 1 and the rear cover plate 3, a certain distance is set between the oil strainer 2, the front cover plate 1 and the rear cover plate 3, the front cover plate 1 is provided with an air inlet 4, and the rear cover plate 3 An air outlet 5 is arranged on the top, and the air inlet 4 and the air outlet 5 are arranged in a staggered interval (that is, the air inlet 3 and the air outlet 4 do not overlap in the vertical direction). There is a rear wing 6 on the rear cover 3 in this embodiment 1, and the rear wing 6 is located at the edge of the air outlet 5 of the rear cover 3. The air inlet 4, the oil filter 2, the rear wing 6, the outlet Air passages 7 for multiple times of oil filtering are for...

Embodiment 2

[0023] The air inlet 4 of the oil fume filter plate in embodiment 2 is a long strip shape with different lengths, and all the long strip air inlets form a circular shape as a whole (see Figure 3), and the air outlet 5 can be rectangular or circular or oval or square. If the air outlet 5 is a round hole or an oval hole or a square hole with the same shape, the rear wing plate 6 should be arranged at the peripheral edge of the air outlet 5 . Other structures of the oil fume filter plate in Embodiment 2 are exactly the same as Embodiment 1.

Embodiment 3

[0025] The air inlet 4 of the oil fume filter plate in embodiment 3 is circular, and all the circular air inlets form a rectangle as a whole (see Figure 4), and the air outlet 5 can be rectangular or circular or oval or square. If the air outlet 5 is a round hole or an oval hole or a square hole with the same shape, the rear wing plate 6 should be arranged at the peripheral edge of the air outlet 5 . Other structures of the oil fume filter plate in this embodiment 3 are exactly the same as those in embodiment 1.

Abstract

The present invention discloses an oil fume filtrating plate of a range hood, including a front cover plate (1), an oil sieve (2) and a back cover plate (3). The oil sieve (2) is placed between the front cover plate (1) and the back cover plate (3). Intervals are respectively arranged between the oil sieve (2) and the front cover plate (1) and between the oil sieve (2) and the back cover plate (3). An air inlet (4) is arranged on the front cover plate (1); an air outlet (5) is arranged on the back cover plate (3). The air inlet (4) and the air outlet (5) are interlaced and alternately arranged. The present invention has a quite simple structure, low manufacturing cost and very good oil fume separating effect. An experiment proves that the purification rate towards the passed oil fume is higher than 90%.

Description

technical field [0001] The invention relates to a range hood, in particular to an oil fume filter plate of the range hood which can separate the oil fume in the gas. Background technique [0002] At present, there are two methods for the oil fume filter used in the range hood: one way is that the oil fume passes through a filter screen placed on the oil fume channel, and the surface oil filter holes can be of any shape and size. When the oil fume passes through, the filter The net absorbs heat, so that the oil in the fume is condensed and filtered on the filter net. Since the oil fume directly passes through the filter screen at one time, only one condensation occurs, and most of the oil fume directly passes through without contact with the filter screen, so the condensation effect of the filter screen on the oil fume is very limited, and the effect and efficiency of oil fume separation are poor; One method is that the oil fume passes through a turning air path composed of ...
