Abstract

The utility model relates to a transverse air inlet style smoke exhaust ventilator, which comprises a casing; wherein, an electric control switch of the exhaust fan, an oil groove, an air deflector, a verge board and an illumination lamp are arranged on the casing. When the exhaust fan is rotated, a negative pressure zone is formed at the top and the back of the range through the air path, and then the oil fume is discharged through the air path just after the oil fume is generated. The utility model solves the problem that the negative pressure zone of the smoke exhaust ventilator on the prior market is too high and the oil fume can not be discharged entirely, so as to abate the contamination of the house caused by the oil fume.

Description

Transverse air-intake formula smoke exhaust ventilator

The utility model relates to a kind of smoke exhaust ventilator, specifically a kind of transverse air-intake formula smoke exhaust ventilator.

The household smoke exhaust ventilator of Chu Shouing is that paperback has one or two pump drainage fan on the metal shell bottom panel in the market, and this pump drainage fan is installed on the casing perpendicular to bottom panel.Also have a kind of smoke exhaust ventilator to adopt centrifugal fan, the direction of operating side of facing the people is contained on the housing, forms a space in the place ahead of blower fan by casing, forms the negative pressuren zone of a basic equal altitudes when motor rotates above cooktop surface.Oil smoke vertical lifting when cooking, be subjected to the restriction of higher-pressure region on every side after, oil smoke flows to low-pressure area, the fan that oil smoke is rotated is discharged outdoor by the air channel.But because the problem in the smoke exhaust ventilator design on the market, the mist extractor that makes is not thorough, and its problem is, in order to satisfy the installation site, do not influence manipulating of people, and the negative pressuren zone that smoke exhaust ventilator is produced is too high, oil smoke is in uphill process, and the convection current air in the environment makes oil smoke break away from negative pressuren zone; With smoke exhaust ventilator install too low, can't manipulate again.Along with people are more and more higher to the requirement of home environment, air quality, standard of living, design a kind of setting height(from bottom) that does not change smoke exhaust ventilator, do not influence people and manipulate, can reduce negative pressuren zone again, be only the developing direction of smoke exhaust ventilator.

The purpose of this utility model is to overcome above-mentioned shortcoming, providing a kind of adopts on the anti-support that is contained in the casing of centrifugal ventilating fan, make ventilating fan back to operation side, the place ahead at ventilating fan, by the cavity deepening of casing back upper place to cooktop surface, make the cooktop surface top form the negative pressuren zone of a band gradient, this form has largely reduced the too high problem of original negative pressuren zone, after oil smoke just forms, just be pumped to outdoor, do not change simultaneously the setting height(from bottom) of smoke exhaust ventilator again, do not influence and manipulate.

To achieve these goals, the technical scheme that the utility model is taked is: comprise a metal chassis 1, casing 1 is by panel, side panel and rear board and top panel are formed, electric-controlled switch 4 is installed on the panel of casing 1, one end of electric-controlled switch 4 is by the wire connecting power plug, the other end connects illuminating lamp 9 and ventilating fan 2, and the opened/closed of control illumination 9 and ventilating fan 2, have a vent on the top panel of casing 1, the place, right angle that top panel and rear board form is equipped with wind deflector 3, the lower end of rear board is equipped with oil holding slot 5, illuminating lamp 9 is installed in the top of panel, panel is connected with the two ends of support 8 respectively with top panel, one or two ventilating fan 2 is installed on the support 8, the top correspondence of ventilating fan 2 be exhaust outlet on the top panel, the bottom correspondence be a oil guide groove on the panel, oil guide groove is led to oil holding slot 5 by the both sides of panel, clear glass wind gathering plate 7 is installed on the two ends, the left and right sides of panel and the both sides panel, between the wind gathering plate 7 with on ventilating fan 2 bottom corresponding panel and the side panel deep bead 6 is installed, but deep bead 6 demolitions are also rotatable, be characterized in, relative operating position is counter is installed on the support 8 for ventilating fan 2, just facing to the rear board of casing 1, form a negative pressure air channel by the both sides panel of casing 1 and top panel and rear board and deep bead 6.

The utility model arrives the rear board deepening of casing near the cooktop surface position, in the cooktop surface back upper place, both sides panel, rear board, deep bead by casing constitute a negative pressuren zone that has gradient, but the also rotatable function of deep bead demolition has made things convenient for the expansion of cleaning and negative pressuren zone.Cooking stove reduces apart from the negative pressuren zone distance, adds the wind gathering plate, makes the generation negative pressuren zone bigger, and the overlay area is wider, and mist extractor speed is faster, more thorough, and the oil smoke vertical lifting is discharged form relatively, has formed a kind of transverse air-intake formula smoke exhaust ventilator of novelty.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a right view of the present utility model.

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

Referring to Fig. 1, Fig. 2, transverse air-intake formula smoke exhaust ventilator of the present utility model, comprise that a metal chassis 1 casing 1 is by panel, side panel and rear board and top panel are formed, electric-controlled switch 4 is installed on the panel of casing 1, one end of electric-controlled switch 4 is by the wire connecting power plug, and the other end connects illuminating lamp 9 and ventilating fan 2, and the opened/closed of control illuminating lamp 9 and ventilating fan 2.Have a vent on the top panel of casing 1, the place, right angle that top panel and rear board form is equipped with wind deflector 3, the lower end of rear board is equipped with oil holding slot 5, illuminating lamp 9 is installed in the top of panel, be connected with the two ends of support 8 respectively between panel and top panel, one or two ventilating fan 2 is installed on the support 8, the top correspondence of ventilating fan 2 be exhaust outlet on the top panel, the bottom correspondence be a oil guide groove on the panel, oil guide groove is led to oil holding slot 5 by the panel both sides, transparent glass wind gathering plate 7 is installed on the two ends, the left and right sides of panel and the both sides panel, between the wind gathering plate 7 with on ventilating fan 2 bottom corresponding panel and the both sides panel deep bead 6 is installed, but deep bead 6 demolitions are also rotatable.

Present embodiment reduces negative pressuren zone under the situation that does not change the smoke exhaust ventilator height, and the ventilating fan place does not have fan housing, in line wind, and discharge capacity is big, noise is low, the effect of easy cleaning thereby reach.

The utility model is reasonable in design, and manufacturing process is simple, realize easily, and be a kind of very good family expenses mist extractor product.
