Abstract

The utility model relates to a cooking fume extractor used in kitchens. A plastic or a metal casing is provided with a dual-spindle bipolar motor which is connected with two turbine blades, and the turbine blades face cooking fume holes in movable casings at both sides. Two doors connected with the top of the casing are covered on an outside point of the cooking fume suction point so as to prevent insects from entering rooms.

Description

Range hood

The utility model relates to a kind of device of eliminating oil smoke for kitchen use, is a kind of range hood for kitchen use.

Existing kitchen smoke exhaust ventilator, fume exhaust fan are played a role to getting rid of kitchen fume, but all have obviously deficiency, and the smoke exhaust ventilator volume is big, is difficult to clean, and oil smoke is got rid of not rapid, and greasy dirt drops on the window and the kitchen range top, and daylighting is affected; Lampblack fan is influenced greatly by natural wind, and oil smoke is difficult to get rid of (rotating speed is oppositely influenced greatly by natural wind simultaneously) to have the part oil smoke to remain in indoor when strong wind, and greasy dirt drops in inside and outside the window of kitchen.

The purpose of this utility model provides the range hood that a kind of twin shaft bipolar machine drives two turbine fan blades, it not only under the big situation of natural wind the oil suction cigarette rapid, and be provided with greasy dirt absorbent foam film, play environmental-protection function, be convenient to cleaning, be beneficial to daylighting.

The purpose of this utility model is achieved in that in a casing (polymer or metal matter), twin shaft the two poles of the earth 220V motor is installed is connected two turbine fan blades, fan blade is (this hole is located in the movable casing in first half both sides) towards casing first half both sides oil suction cigarette hole, i.e. turbine fan blade oil suction cigarette thus.Oil suction cigarette outlet duct divides twice, the casing top becomes curved surface with the front intersection, but also squarely, begin to positive bottom (if outlet flue is not crooked from curved surface, dwindle and can be fixedly casing), casing first half both sides are movable casing, movable casing is inside spill, to prevent that greasy dirt from flowing to outside the shell, the casing front is a frame muscle, casing first half vertical direction center is established motor skeleton frame and dividing plate is installed, and dividing plate is established in latter half vertical direction center, casing top and bottom interior wall are established clamping foamed plastics film absorption greasy dirt (the visual greasy dirt situation of this film and change or clean), establish foam plastic film or net simultaneously in turbine fan blade termination with the absorption greasy dirt.The movable casing in casing first half both sides is an axle bed with the casing installing frame, near shell limit, positive place and establish fixedly card or screw and casing on the frame muscle and fix.The movable casing in positive and both sides can be opened when cleaning.In that oil suction cigarette hole peripheral hardware-the U type is two-door, door is provided with upset back steady pin, this door is crossed over the casing top, topped two oil suction cigarette holes, establish this two-door turning cylinder at the casing top, also establish the two-door steady pin card in upset back in addition, when using range hood, with two-door upset to the casing top, when stopping using, two-door upset is to the outside, oil suction cigarette hole, enter the room to block worm fly etc., or adopt and do not establish two-door and establish a loose-leaf door, promptly export the first half and be fixing casing at flue outlet, Lower Half is little loose-leaf door, or establishes big or small half of loose-leaf door.

This machine adopts the twin shaft bipolar machine to drive two turbine fan blades simultaneously, under the situation that does not increase power, can realize promptly absorbing two oil smoke on the pot simultaneously than the fume exhaust fan of existing two power motors of the same race perfect functions more, be a kind of energy-saving product design.

Because adopt such scheme, the utility model can reach under the big situation of natural wind, get rid of oil smoke (it is minimum influenced by natural wind) rapidly, the greasy dirt absorption affinity is strong, is convenient to cleaning, is beneficial to the purpose of daylighting.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

In the drawings, two-door 2 are connected with casing 1 by two-door axle 4, turbine fan blade 5 is connected with motor 14 by motor twin shaft 19, twin shaft bipolar machine 14 is installed skeleton frame 15 with motor and is connected, activity casing 8 in first half both sides is fixed with casing 1 by movable casing axle bed 10 in both sides and the fixing card of movable casing (or screw) 18 and is opened, switch 17 is installed in the positive bottom of casing, oil smoke outlet 11, latter half of buffler 12, motor is installed skeleton frame and dividing plate 15 is located at the positive center of casing 1 vertical direction, movable casing frame muscle 21, positive movable casing axle sleeve 22 and casing 1 one, keep away at the bottom of the top of foamed plastics film 16 by clamping bar and casing 1 and be connected, fan blade turbine termination foamed plastics film 23 is fixed on turbine fan blade termination.Complete machine is connected with the kitchen window through installing hole 13 by installing frame 9.

Claims

A kind of range hood of eliminating oil smoke for kitchen use, it is characterized in that: the twin shaft bipolar machine is installed in casing is connected two turbine fan blades, oil suction cigarette hole peripheral hardware is connected in the two-door of casing top, or establish a loose-leaf door at the smoke road junction, the first half both sides are movable casing, the oil suction cigarette hole of turbine fan blade in the movable casing in both sides.
