Abstract

The utility model discloses a high-efficiency condensation net for a range hood. The high-efficiency condensation net comprises a netty condensation plate with a plurality of net pores, the calibers of the net pores are gradually enlarged along an oil smoke inlet direction, and the net pores are tapered pores which are small in the front part and large in the back part. The high-efficiency condensation net has the beneficial effects that the calibers of the net pores of the condensation net are narrower than those of air outlets, so that noises caused by collision between oil smoke and the side wall of each net pore can be reduced; a pressure intensity difference is formed between the inner parts and the outer parts of the net pores according to an aerodynamic principle, so that a certain condensation effect can be achieved, and the oil smoke can be quickly cooled; and the rotation of the oil smoke in an inner cavity of a range hood body can be improved due to the structural design that each net pore is small in the outer part and large in the inner part, so that the probability of collision between oil smoke condensation oil droplets and the wall of the inner cavity can be improved, and the emission load of the oil smoke to an external environment can be reduced.

Description

A kind of range hood high-efficiency condensation net

Technical field

The utility model relates to a kind of condensation net that is applicable on range hood.

Background technology

Range hood condensation net of the prior art is generally steel wire, be fixed on the exhaust fume collecting hood surface of range hood shell, before entering range hood, oil smoke first carries out the condensation filtration treatment through the condensation net, carrying out for the first time, oil smoke separates, carry out again centrifugation in blower fan, make to be discharged to outdoor air oil smoke content reduction.Range hood can produce very large noise in the course of the work, this noise mainly comes from vane rotary noise and air-flow turbulence noise, the height of range hood work noise and oil smoke discharge amount be how much two important indicators to its performance evaluation, in prior art, the improvement of noise and the control of oil smoke discharge amount are focused mostly in the design of gas channel; The present invention is intended to break through from the structural design of condensation net, and the first link that sucks from oil smoke namely begins to fall the sound noise abatement, controls discharging.

Summary of the invention

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of range hood high-efficiency condensation net is characterized in that: comprise the netted cold plate that is provided with some mesh, described mesh bore becomes greatly gradually along the oil smoke Way in, is pre-small post-large bellmouth.

The beneficial effects of the utility model are: the mesh bore air inlet of the utility model condensation net is narrower than the gas outlet, can reduce the collision noise of soot gas and mesh sidewall, utilize simultaneously aerodynamic principle, the inside and outside pressure difference that forms of mesh, reach certain condensation effect, make oil smoke cooling rapidly, the outer little interior large structural design of mesh can strengthen oil smoke in the rotation of body inner chamber, improve the collision probability of oil smoke condensation oil droplet and internal chamber wall, strengthen the collecting effect of excessive fuel consumption on cool solidifying plate, reduce oil smoke toward the discharge capacity of extraneous environment.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is local amplification view of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of range hood high-efficiency condensation net comprises the netted cold plate 1 that is provided with some mesh 2, and described mesh 2 bores become greatly gradually along the oil smoke Way in, are pre-small post-large bellmouth.

The mesh bore air inlet of the utility model condensation net is narrower than the gas outlet, can reduce the collision of oil smoke and mesh sidewall, and the initial stage flowing velocity that sucks due to oil smoke is very high, and the collision of itself and mesh sidewall greatly reduces the pneumatic noise that helps to reduce lampblack absorber; Simultaneously, this structural design has been utilized aerodynamic principle, make the inside and outside pressure difference that forms of mesh, thereby reach certain condensation effect, make oil smoke cooling rapidly, and, can strengthen oil smoke in the rotation of body inner chamber, improve the collision probability of oil smoke condensation oil droplet and internal chamber wall, strengthen the collecting effect of excessive fuel consumption on cool solidifying plate, reduce oil smoke toward the discharge capacity of extraneous environment.

The utility model is simple in structure, result of use good, can be widely used in various range hoods.

Claims

1. range hood high-efficiency condensation net, it is characterized in that: comprise the netted cold plate (1) that is provided with some mesh (2), described mesh (2) bore becomes greatly gradually along the oil smoke Way in, is pre-small post-large bellmouth.
