Abstract

The utility model relates to an air curtain type oil fume exhauster which is a device used for preventing oil fume from escaping by the air curtain blown out from the oil fume exhauster which is a daily electrical appliance. The utility model is composed of an air storing box, an air indraft motor and telescopic ducts, wherein the air storing box is arranged above the front side of the oil fume exhauster and is connected with two telescopic ducts which are fixed along the edge of a bottom board. Air nozzles arranged on the ducts can jet the air curtain to prevent the escaped oil fume. Thus, the environmental pollution is prevented, a comfortable work environment is brought for operators, and the fume preventing effect of the utility model outclasses the measures of the fume baffle class.

Description

Air-curtain cooker hood

A kind of wind curtain type smoke exhaust, it belongs to daily-use electrical appliance, is the structure that prevents oil smoke diffusing a kind of blowing becoming air curtain outward.

In order to make the Kitchen hygiene cleaning, people have installed smoke exhaust and have got rid of flue dust, but smoke exhaust can only be discharged most flue gas of frying in shallow oil stir-fry, fry and all the other partly overflow contaminated environment and apparatus by the restriction of its structure.Installation smoke barrier and bilateral plug of tobacco plate on smoke exhaust have been adopted in order to overcome this defective people, and means such as cross air blasting before the smoke barrier, but can't stop oil smoke excessive and use smoke barrier still must often to clean, adopt blowing and cause pipe interior to pollute defective.Therefore the excessive of oil smoke brought puzzlement to people.

The purpose of this utility model is to propose a kind of the blowing to form air curtain around range fan shell, prevents that oil smoke is excessive.It overcomes the smoke exhaust weak point.

The utility model realize in the following way it constitute by storage bellows, air draught motor, blast pipe, flexible pipeline.The storage bellows are contained on the range fan shell front end top board, in the storage bellows air draught motor is housed, have air inlet on the motor top casing, install one on the air inlet by bottom tube and rotatable elbow union blast pipe dimerous, be equipped with on the mouth of pipe by coarse filtration layer and the thin two-layer filtering bodies of filter course, storage bellows front end is shaped on two heterointerfaces that stretch out, they connect two respectively, dish is contained on the shell bottom plate periphery, by the adjustable and retractable pipe that a plurality of telescopic joints and a plurality of fixed knot are formed, be shaped on the flanged air nozzle of rectangle on each fixed knot and inlay in the moulding hole that is enclosed within on the smoke exhaust plate.

The utility model air curtain smoke exhaust has following advantage:

1, rectangle air nozzle, the clean air air-flow of ejection forms a rectangle air curtain, excessive oil smoke is blown back discharged by smoke exhaust to make oil smoke outer diffusing and make a heat insulation comfortable operating environment to the operator.

2, because the coarse filtration of the air inlet mosquito proof of blast pipe and the thin filtration of preventing dust.Therefore it can not pollute pipe interior, and the few direction air inlet of the rotatable selection oil smoke of air inlet.

3, owing to the air curtain structure, its retaining cigarette effect is much better than smoke barrier, and it prevents that effectively oil smoke from loosing and the cleaning of maintenance operation room outward.

Accompanying drawing and drawing explanation:

Accompanying drawing 1 wind curtain type smoke exhaust outline drawing

Accompanying drawing 2 wind curtain type smoke exhaust cutaway views

Thick, the thin filter course enlarged drawing of accompanying drawing 3 blast pipes

Accompanying drawing 4 flexible pipelines, air nozzle fixed structure chart

In conjunction with the accompanying drawings the utility model is described further below by embodiment:

This smoke exhaust is by shell, fan, motors etc. are made, its air curtain system is by storage bellows 2, air draught motor 4, blast pipe 3 and flexible pipeline 5 constitute, its structure such as accompanying drawing 1, shown in 2, in range fan shell front end top board 6 beveled mouth storage bellows 2 are housed, an air draught motor 4 is arranged in the casing, on air draught motor top, be shaped on an air inlet 7, blast pipe bottom tube 8 of fixed installation on it, a colloid liner is housed on the top, top of top suit has elbow can be at bottom tube 8, the elbow union 9 of last rotation is equipped with the filtering bodies of thin filter course 14 and coarse filtration layer 10 on the mouth of pipe.As see shown in the accompanying drawing 3, storage bellows front end is equipped with two heterointerfaces that stretch out 15, it connects two respectively by a plurality of fixed knots 17 and a plurality of telescopic joint 16, the flexible airduct of forming 5, on each fixed knot, be shaped on the air nozzle 18 of a band projection, two flexible pipelines along smoke exhaust front end inferior horn position respectively backward along extending left and right side plate 13 and base plate 11, shown in the end accompanying drawing 1 at angle position, and make the air nozzle 18 on each fixed knot, edge is enclosed within the moulding hole 19 on this position base plate 11 as shown in Figure 4.Air after 4 work of air draught motor are filtered by blast pipe 3 inspirations in the use is entered by air inlet 7, enters flexible pipeline 5 through heterointerface 15, forms air curtain through each air nozzle 18 ejection and stops that oil smoke is excessive.
