Abstract
The utility model discloses a lifting type oil hood belonging to a centralized fume exhausting device. The utility model is composed of an air hood, a telescopic oil fume sucking barrel, and an axial flow fan (a machine case), and the telescopic oil fume sucking barrel is formed by that a plurality of frustum barrels with variable cross sections are sheathed with each other. One end of the telescopic oil fume sucking barrel is connected with the air hood; the other end is connected with the machine case; a fume exhausting port of the machine case is connected with a fume channel; a lifting threaded bolt control handle is installed in the telescopic oil fume sucking barrel; the handle is utilized to control the air hood to be at different heights. The utility model can achieve the purposes of hood lifting, high efficiency of fume suction, and centralized fume exhaust.
Description
The utility model relates to a kind of kitchen oil suction cigarette device.
Kitchen fume is indoor a kind of air pollution source, and people have invented smoke exhaust ventilator and solved a lot of problems, but awaits improving.Ultrathin smoke exhaust ventilator, vision is good, and striving rate is low, noise is big; Though dark bell-type has improved purifying rate, it is many to take up room, and noise is still inevitable, someone has designed the smoke exhaust ventilator that a kind of fume extracting box separates with blower fan, and it has improved striving rate and has reduced noise again, but the too low influence operation of fume extracting box, too light fume extracting box can not in time be got rid of the heat radiation of oil smoke to human body, the oil smoke side entrance strengthens dynamo-electric energy consumption, and blower fan is installed on outdoor, be unfavorable for C﹠M, outside the direct drain chamber of oil smoke, cause the exterior wall greasy dirt full of stains or spots, influence the appearance of the city.Chinese patent 89208067,89207517 etc. has provided a kind of smoke exhaust ventilator of liftable lampblack-sucking cover, has improved oil suction cigarette efficient, but thinking only is provided mostly, adopts the flexible life-span of flexible pipe short, and the design lifting motor is then too complicated
The purpose of this utility model is the range hood that a kind of liftable of design is inhaled bonnet, and is connected central exhaust with flue.
The utility model is made up of fan housing, flexible oil suction chimney, axial flow blower (cabinet), and flexible oil suction chimney is nested by some joint variable cross-section frustum drums and forms.Flexible oil suction chimney one end links to each other with fan housing, and the other end connects cabinet, and the cabinet outlet connects flue, adorns lifting control mechanism in flexible oil suction chimney, is gone up at various height by handle control fan housing.
Because the utility model can be adjusted the fan housing height according to the cooking needs, has given full play to the effect of smoke exhaust ventilator.Lifting oil suction chimney (cover) can directly be loaded on the smoking port of existing range hood, improves purifying rate
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model connecting rod, piston structure figure.
Fig. 3 is the utility model transformation threeway mouth structure figure;
Form by fan housing (1), flexible oil suction chimney (2), axial flow blower (cabinet), transformation three ports (9), mozzle (11) and smokejack (10) etc. in the present embodiment.Flexible smoking tube (2) is nested by some traitorous cross sections frustum drum and forms, and goes up joint most and is fixed on the attached wall support (3), and the most following joint tube is connected interior dress lifting bolt joystick with fan housing; The spiral shell connecting rod piston of fan housing (1), oil suction chimney (2) armrest handle blocks the slip of about two-layer smoking tube, thereby the control fan housing is gone up at various height.Flexible oil suction chimney (2) is linked to each other with bellows (5) by corrugated tube (4), axial flow blower (6) is arranged in the bellows (5), in bellows (5) outlet one check valve (7) is arranged, bellows (5) are discharged oil smoke in flue (10) by elbow bend (8) through transformation three ports (9), in bellows (5) below one P shape oil guide pipe (11) are arranged.
Lifting bolt controlling organization (referring to Fig. 2), form by fixed mount (15), shank of bolt (12), handle (13) etc., it is loaded on and descends most on the joint telescoping tube (2), connecting rod (17) can pass tube wall upper piston hole and contact outer retracting cylinder (2), wanting connecting rod (17) end is a piston (18), raise or reduce screw rod (12) control link (17) and stretch out piston (18) and head on outer retracting cylinder (2) by the rotation of handle (13), reach the purpose of location height.
The utility model transformation three ports (referring to Fig. 3) have a deflector (19) along the side pipe airflow direction, and are higher than the center line of side pipe, and effect is that water conservancy diversion prevents that the flue collector oil smoke from entering in the by-path.
Claims (3)
1, a kind of lift oil cover and concentrated oily fume exhauster, form by main fan housing, flexible oil suction chimney, axial flow blower (cabinet), the oil suction chimney that it is characterized in that stretching is nested by some joint variable cross-section frustum drums and forms, flexible oil suction chimney one end links to each other with fan housing, the other end connects cabinet, axial flow blower is arranged in the cabinet, in flexible oil suction chimney, adorn lifting control mechanism.
2, according to the lift oil smoke cover and the concentrated oily fume exhauster of claim 1, it is further characterized in that bellows (5) oil extraction mouth has a check valve (7), and is connected on the flue by transformation three ports.
3, according to the lift oil smoke cover and the concentrated oily fume exhauster of claim 1, it is characterized in that transformation three ports have deflector (19) along the side pipe direction, and be higher than the side pipe center line.
