Description

The inclined type main body of deep kitchen ventilator

The utility model belongs to household electrical appliance, is a kind of improvement to existing deep kitchen ventilator main body structure.

Recently deep kitchen ventilator is little because of the blast that can solve slim machine preferably in the city, and blowdown rate is low and be difficult for deficiency such as coordination with the kitchen apparatus hanging cupboard, and fades in its gesture, is progressively favored by people.But these dark type machines are that oil suction cigarette system is vertically arranged mostly, though such structure can so that sump oil more quickly stream gather in catchment cup, but because of it must all be loaded on parts such as motor and impeller in this vertical body, and make its width almost account for more than 2/3 of exhaust fume collecting hood casing overall width, make the volume size that the oil-collecting cigarette is used, particularly work as oil smoke more for a long time, many oil smoke are stopped by this place in the process that makes progress, can not enter smoothly in the exhaust fume collecting hood and go out from the both sides transpiration, these cause influences the blowdown rate of this type of dark type machine.In addition, the overhead type oil suction cigarette system that some dark type machine has adopted level to install, and have deficiency such as the smooth and oily weak effect of blowdown of stream oil.Thereby still be necessary further improvement.

It is too little because of the volume that adopts rectilinear main body to exist to take case inner volume ambassador oil-collecting cigarette that the purpose of this utility model is to overcome existing deep kitchen ventilator, easily cause the part oil fume outer-runaway to influence blowdown rate, reaching the main body that adopts overhead type has deficiencies such as the smooth blowdown oil of stream oil weak effect again, and a kind of inclined type main body of deep kitchen ventilator is provided.

Content of the present utility model is such: the arrangement one that is ramp type on the top of box house is by motor, impeller, blade wheel chamber, oil suction mouth and change the fume exhaust system that parts such as airduct are formed, and makes formation one angle between the rearing-box plate of the baseplane of oil suction mouth and casing; For ease of installing, each pin of angle and inferior horn removes Yi Xiaojiao on the upper surface of blade wheel chamber, to make full use of the casing bight, increases the collection cigarette volume in the case; Because the structure of inclined type is smooth and easy for making air draft, change airduct and between blade wheel chamber and box cover plate, install one additional; Illuminating lamp chamber and catchment cup all install below blade wheel chamber.The utility model cooperates with front shroud can form novel deep kitchen ventilator.

The deep kitchen ventilator that adopts the utility model to form is compared following advantage and good effect with existing deep kitchen ventilator: 1. the top that is installed in casing fume exhaust system inclined type, make full use of the volume at case angle, it is little to take the case internal volume, the lower box space increases, the soot gas of rising is all assembled within it, and the collection mist extractor is effective.2. fume exhaust system inclined type ground mounting structure can make internal body and the surperficial sump oil of being stained with trickle along the inclined-plane, and afflux oil is quick, and oil-proof, not following, oil extraction is totally thorough.3. oil-collecting cigarette volume is big, catches the cigarette ability and strengthens, and has reduced the oil fume outer-runaway phenomenon, and blowdown rate improves.4. the lighting window of arc surfaced, plane of illumination is bigger.5. it is convenient to clean, and needn't dismantle parts such as cabinet fully and can will be stained with in the greasy dirt on surface and clean cleaning, easy to operation.
