Abstract
The utility model relates to a pressure difference air induced cooker hood for ventilation. A small opening of the top of a fume collecting hood is provided with a right-angle bent pipe flue beside which a blower casing communicated with the flue is arranged. An impeller, a rotating shaft of which is horizontally arranged and a motor are arranged in the blower casing. Two outward convex inflow air pressure covers covering on through holes of both sides of the blower casing also extend toward the exhaust end of the flue along the flue. The utility model has no scale for long term utilization and relieves the cleaning worry of people. A small amount of fume gas can be automatically discharged, and the utility model has the advantage of electric energy saving.
Description
The utility model relates to a kind of ventilation unit, especially for the device of kitchen ventilation.
Though existing smoke exhaust kind for household use is a lot, but their structure all is to be provided with impeller in exhaust fume collecting hood opening part or flue basically, and its weak point is that impeller directly contacts oil smoke, and the short time will be tied full grease, cause induction-motor load to increase, start difficulty and finally stop operating.
The pressure reduction induced air type smoke exhaust that provides a kind of impeller not contact with oil smoke substantially is provided in view of above-mentioned weak point the purpose of this utility model of the prior art.
The purpose of this utility model can realize by following measure: a kind of pressure reduction induced air type smoke exhaust that is used to ventilate, it is to be provided with the right-angle elbow pipe flue at the little opening part in exhaust fume collecting hood top, it is characterized in that: be attached thereto logical Fan casing other the establishing of flue, be provided with horizontally disposed impeller of rotating shaft and motor in it, the air inlet gland that covers two evaginations of Fan casing two side through hole also extends to its exhaust end along flue.Preferably flue is made up of the two halves that separate along center line.Blower Housing is located at crook, flue right angle.
The utility model mainly is to be provided with motor and impeller in the logical chamber other being attached thereto of flue.
The utility model mainly is made up of exhaust fume collecting hood, flue, air inlet gland, motor, impeller and Fan casing.Wherein exhaust fume collecting hood and the conventional identical flare of exhaust fume collecting hood, the little opening part in top links to each other with flue by fixture.Flue is a right-angle elbow pipe, and it can be pipe, also can be square tube; They can be all-in-one-piece, also can be the two halves that separate along center line constitute knockdown so that take cleaning apart.Be attached thereto logical Fan casing other being provided with of this flue, it preferably is located at the crook, right angle.The cavity of this Fan casing is to be made of another housing that links to each other with the flue housing, it can be and the corresponding two halves of combined type flue, also can be to be flute profile with the corresponding housing of monoblock type flue directly to link to each other with the flue housing, openend then be provided with the end cap that is attached thereto.The through hole of air inlet is established in two sides at Fan casing.The motor that is provided with impeller and is attached thereto in Fan casing, the rotating shaft of its impeller is horizontally disposed with.Preferably motor stator is provided with impeller, and it rotates, and not only air circulation is big, and the volume of Fan casing is again little, and motionless two ends of rotor can be fixed on the Fan casing both sides by fixture, and motor is located.Also be provided with the air inlet gland in the Fan casing both sides, though its part can will be provided with Fan casing both sides of through hole cover, another part extends to its exhaust end along flue, all evagination make it and Fan casing and flue between keep certain interval.Impeller rotation when starting motor, fresh air enters from air inlet gland openend, and the through hole by the Fan casing both sides enters in the Fan casing again, and then discharges from flue.Because air velocity makes soon and produces pressure in the flue and fall, so flue gas in exhaust fume collecting hood enters flue rapidly and drains together with fresh air below it, and motor can directly not contact so just with oil smoke with impeller and can prevent fouling on it.
Drawing is described as follows:
Fig. 1 is a front elevational schematic of the present utility model.
Fig. 2 is a schematic top plan view of the present utility model.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the schematic diagram of pressure reduction induced air type smoke exhaust illustrated in figures 1 and 2, the little opening part in tubaeform exhaust fume collecting hood 1 top is linked to each other it by screw with flue 2.The two halves of square tube shape flue for separating along center line, both overlap joints, its free end can be connected to other chimney as required.Be provided with in the crook, right angle of flue and be attached thereto logical Fan casing 3, be provided with check valve at both places of being connected, this Fan casing is dimidiation also, and per half housing fuses with the flue housing respectively, and both also are overlap joints.Be provided with the through hole of air inlet in the both sides of Fan casing, and central through hole then is provided with the connector that fixed motor 4 is located the two halves flue simultaneously.The impeller that links to each other with motor 5 its rotating shafts that are positioned at Fan casing are for being horizontally disposed with, also be provided with air inlet gland 6 in both sides, Blower Housing outside, the housing part of its evagination covers the pore of Fan casing both sides, and another part then extends to its exhaust end along flue, so that reach outdoor.
The utility model has following advantage compared to existing technology:
1. motor and impeller use also non-scaling for a long time, remove the often worry of cleaning of consumer. Even clean also very easy.
2. when motor was not worked, because flue is unimpeded, but a small amount of flue gas Self-discharged was saved electric energy.
3. the utility model can two be together in parallel, and uses simultaneously to adapt to a plurality of cooking stoves.
Claims (3)
1, a kind of pressure reduction induced air type smoke exhaust that is used to ventilate, it is to be provided with the right-angle elbow pipe flue at the little opening part in exhaust fume collecting hood top, it is characterized in that: be attached thereto logical Fan casing other the establishing of flue, be provided with horizontally disposed impeller of rotating shaft and motor in it, the air inlet gland that covers two evaginations of Fan casing two side through hole also extends to its exhaust end along flue.
2, pressure reduction induced air type smoke exhaust according to claim 1, it is characterized in that: flue is made up of the two halves that separate along center line.
