Description

The position adjustable smoke exhaust ventilator

The utility model relates to a kind of oil smoke and removes equipment, claims the position adjustable smoke exhaust ventilator again, and it is suitable for the eliminating and the cleaning of kitchen fume.

The removing equipment of kitchen fume has experienced two developing stage, and the typical products of phase I is an exhaust fan, is referred to as first generation fume exhaust equipment; The typical products of second stage is a smoke exhaust ventilator, is referred to as second generation fume exhaust equipment.Exhaust fan is simple in structure, cheap, but oil extraction efficient is not high, still keeps certain market share in today; Smoke exhaust ventilator has then captured the staple market of kitchen fume cleaning equipment with its better mist extractor effect.Though the brand of at present popular on the market smoke exhaust ventilator is very many, but still many shortcomings are arranged, as: (1) oil smoke can not be discharged from fully, still can be detained more oil smoke in the kitchen; (2) installation site is fixed, and can't adjust, if the installation site is too far away from stove and accessory, influences the smoke pumping effect, and is too near, the operation when then influencing cooking; (3) fan is installed on the hood, causes the hood complex structure, and volume is big, and weight is big, and power consumption is bigger; (4) adopt the double end fan design mostly, but the chance that the double end fan is worked simultaneously is few, so service efficiency is not high; (5) the easily sticking oil in the surface of smoke exhaust ventilator, and because the dismounting difficulty is difficult to cleaning.

The purpose of this utility model provides a kind of efficient, flexible, light-duty, graceful, cleaning, cheap novel fume exhaust equipment.

The purpose of this utility model is achieved in that installs scavenger fan on buildings such as window, filter is installed by import department at scavenger fan, scavenger fan is connected with an end of adapter by a soft air flue, adapter is fixed on by an adjustable support on the buildings such as body of wall, filter is installed in taking over, take over the other end fan housing and inner support are installed, airflow guidance device and oil collector sump tank are installed on inner support, when scavenger fan is worked, the air of cooker top is sucked by the horn-like annular space between fan housing and airflow guidance device, through taking over, soft air flue, scavenger fan and be discharged to outdoor, simultaneously, oil gas in the outflow process through airflow guidance device, adapter is separated from air with filter, and is collected in the oil catcher.

The utility model by the fan postposition, four big unique design such as fan housing is adjustable, air-flow guiding, mist of oil filtration improve the smoke exhaust ventilator performance comprehensively.Be put into the exit by scavenger fan is changed by the porch of lampblack absorber, make that the air-flow in the soft air flue becomes suction condition by the original state that blows out, gas flow character also becomes laminar flow by turbulent flow, thereby minimizing energy loss, improve oil extraction efficient, the fan number also only needs one, has reduced cost and energy consumption, owing to do not have fan in the fan housing, make the capouch designs simplification, volume reduces, and weight reduces, fan housing can come in every shape, and changes or unpicks and washes conveniently; By random adjustment adjustable support, can change the position and the attitude of adapter, thereby make the position of fan housing and attitude can arbitrarily adjust to an optimum operating position, to obtain best smoke pumping effect; By airflow guidance device is set, make it and fan housing between form an annular air-flow path, can quicken pot face air all around on the one hand and enter fan housing, and air-flow is moved twist, help Oil-gas Separation and collection, on the other hand, pot face center air can't directly enter fan housing, thereby has reduced the volatilization of oil smoke; By the mist of oil filter is set, in soft air flue porch, filter and to get rid of remaining mist of oil after the screw, in soft air flue exit, filter once more, and filter can be changed easily.So the invention provides a kind of efficient, flexible, light-duty, graceful, cleaning, cheap novel fume exhaust equipment.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
