Description

Wholly sucking on-wall type kitchen hood

The utility model belongs to household electrical appliance, is a kind of improvement to existing kitchen hood, is mainly used in the family kitchen suction and removing to the greasy dirt air.

Existing kitchen hood product mainly contains slim machine and dark type machine etc.Recently dark type machine fades in its gesture because of deficiencies such as the oil-collecting cigarette difference that can solve slim machine preferably and blowdown rate are low in the city, is progressively favored by people.But this two classes type adopts the oil suction cigarette system of mixed-flow or centrifugal fan mostly, and blast too concentrates on around the oil suction mouth, and still has careless and sloppy oil smoke to front shroud and both sides to be overflowed, and has influenced blowdown rate.In addition, reason owing to component mounting structure aspects such as the motor of these types and impellers, and make its exhaust fume collecting hood casing thickness seem too wide, even exceed the width of the kitchen range top, very easily meet and discuss in the use and hinder operation, and deficiency roomy and difficult because of it and that the kitchen finishing especially is difficult for and the device hanging cupboard is coordinated mutually, and itself install also inconvenient.Above-mentioned these reasons are made troubles to use, thereby still are necessary further improvement.

The purpose of this utility model is to overcome existing kitchen hood because of problems such as the oil-collecting cigarette difference that adopts mixed-flow or centrifugal blower fan system that blast is too concentrated to still have oil smoke partly to be overflowed to exist and blowdown rate are low, and exhaust fume collecting hood casing thickness is too wide and influence that bring is used and deficiency such as installation, and a kind of wholly sucking on-wall type kitchen hood that adopts the thin body of cross flow blower is provided.

Content of the present utility model is such: the two ends of central part in a thin bodily form main box, fix a motor and a holder respectively, and between is equipped with a blade wheel chamber and a long impeller, one of the composition that is vertical formula upwards communicates with exhaust outlet, the downward cross flow blower fume exhaust system that communicates with the oil suction mouth, formation is with the wholly sucking structure in whole main box front, between two side end faces of oil suction mouth and main box, protection net is housed, can make safe and attractive in appearance, illuminating lamp chamber and oil collection box also are equipped with in the bottom, and the switch control box is installed in the top of main box outside.

The utility model has been compared following advantage and good effect with existing kitchen hood: adopt cross flow blower fume exhaust system 1., can make and form a suction ground structure comprehensively between the main box front, suction force distributes wide, the soot gas of rising is all evenly aspirated away, reduced the excessive phenomenon of oil smoke, blowdown rate improves, and the collection mist extractor is effective.2. adopt cross flow blower fume exhaust system, and vertically formula ground is installed, it is little to take the cover internal volume, its thickness is reduced and forms thin bodily form wall-hanging structure, the installation that is beneficial to body itself with coordinate mutually with other facilities.Security performance is good, does not have the phenomenon of meeting and discussing, and does not hinder operation.3. good looking appearance, the internal structure compactness.And can make internal body and the surperficial sump oil of being stained be easy to adfluxion, and afflux oil is quick, oil-proof, does not drip extension, and oil extraction is totally thorough.4. oil suction mouth face width is wide, and windage is few, weakens and reduced noise.5. easy to use, clean easily, simple to operate.
