Abstract

The utility model discloses a cooking fume separating hood for the cooking fume ventilation machine, which belongs to an accessory of air cleaning equipment, in particular to a cooking fume separating hood for the kitchen with cooking fume ventilation machine. The utility model can solve the problems of the prior filter in the ventilation machine, the problems are that the separating efficiency is low and the cooking fume removing effect is insufficient. The utility model provides a cooking fume separating hood shaped in truncated-cone which containing mutually-spaced inner and outer layers, the inner and outer layers are provided with punch-flanged holes and sink blind holes forming a bending wind passage. Compared to the prior art, the utility model has the advantages that the bent smoke passage can be formed, after the cooking fume enters the bent passage at high speed, the flowing direction has to be changed times abruptly, and thousands of small swirls striking on the separating board are formed, the tiny oil droplets stick to the separating board and fall to the oil cup, thereby speeding up the separation of the cooking fume. The oil cup collects oil is arranged on the hood bottom for easy cleaning.

Description

Smoke exhaust ventilator oil smoke separation hood

Technical field

The utility model belongs to the annex of air cleaning facility, particularly a kind of smoke exhaust ventilator oil smoke separating plate.

Background technology

When people carry out operation in the kitchen, often suffer the invasion and attack of oil smoke, the major measure of getting rid of oil smoke at present in the kitchen is to use to carry out the smoke exhaust ventilator that oil smoke separates, but the separation of the oil smoke of present most of smoke exhaust ventilators all is to adopt filter net type, the oil smoke separation rate is low, and the effect of getting rid of oil smoke is bad.

The utility model content

The purpose of this utility model is exactly the deficiency that exists at the cooking fume filter in the above-mentioned existing smoke exhaust ventilator, and a kind of bending air channel that forms is provided, and improves the oil smoke separation rate, strengthens the smoke exhaust ventilator oil smoke separation hood of getting rid of the oil smoke effect.

The purpose of this utility model realizes by following technical proposals:

Smoke exhaust ventilator oil smoke separation hood, the oil smoke separation hood is tapered, is made of surface layer and nexine, have between surface layer and the nexine at interval, offer on the surface layer to dash and roll flanging hole one, interlace successively on the nexine to offer to dash and roll flanging hole two and spill blind hole, towards rolling flanging hole one and communicating towards rolling flanging hole two.

Dash and roll flanging hole one and spill blind hole position correspondence.

Dash roll flanging hole one for outer little in big slot.

Dash roll flanging hole two for outer big in little slot.

The spill blind hole be outer big in little Long Circle hole.

The oil smoke separation hood is a truncated cone, and under the last size, the bottom is provided with lubricating cup.

The beneficial effects of the utility model are, interval between surface layer and the nexine constitutes the air channel of bending, when soot gas enters the bending air channel at a high speed, repeatedly sharply change wind direction, form ten hundreds of micro cyclones and clash into separating plate, small elaioleucite sticks on the separating plate and flows into lubricating cup, separates to quicken oil smoke, and the lubricating cup that the bottom is provided with can gather the oil of separation.

Number in the figure, the 1st, surface layer, the 2nd, nexine, the 3rd, dash and roll flanging hole one, 4th, dash and roll flanging hole two, 5th, spill blind hole, the 6th, lubricating cup.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described.

As shown in figures 1 and 3, smoke exhaust ventilator oil smoke separation hood profile is round urniform, last size down, the bottom is provided with lubricating cup 6, be evenly distributed with on the cover body of oil smoke separation hood to dash and roll flanging hole 3, dash and roll flanging hole 3 for square, as shown in Figure 2, the cover body of oil smoke separation hood constitutes by surface layer 1 and nexine 2 are two-layer altogether, has at interval between two-layer, offer on the surface layer 1 be shaped as outer little in big dashing of slot roll flanging hole 1, interlace successively on the nexine 2 to offer to dash and roll flanging hole 24 and spill blind hole 5, spill blind hole 5 is little in outer big, and the position of spill blind hole 5 is with to dash the position of rolling flanging hole 1 corresponding, dashes to roll flanging hole 1 and dash and rolls flanging hole 24 and communicate, interval between surface layer 1 and nexine 2 constitutes the air channel of bending, oil smoke enters the air channel of this bending at a high speed under the effect of smoke exhaust ventilator fan, the arrow among Fig. 2 has been represented the motion path of oil smoke in the bending air channel, form vortex, the acceleration oil smoke separates, and improves the oil smoke separation rate, strengthens the effect of getting rid of oil smoke.
