Description

Wall dual-hole oil soot extractor

The invention belongs to kitchen utensils.

Prior art, the inventor has applied for a " wall type oil vapour extractor " utility model patent (March 5 1991 applying date, and announce) 12 months forward direction Patent Office of the People's Republic of China in 1991 the 7th phases the 50th volume utility model patent communique.As shown in Figure 1, it have one pasting that stove wall installs itself not with blower fan, the single hole wall-attaching type smoking cover 1 of open type, owing to itself be not with blower fan, volume is little, under the condition that does not influence cooking sight line, can make the smoking port of smoking cover more approach frying pan, the comparable original suspension type smoke exhaust ventilator of its distance of smoking shortens 1 times and (foreshortens to 300 millimeters by 650, as shown in Figure 2), thereby can reach the purpose that improves smoking efficient.Its weak point is that the single hole wall type oil vapour extractor can only use for a cooking stove, use simultaneously as two cooking stoves, then must adopt two kitchen range single hole wall type oil vapour extractors of forming side by side by two single hole wall-attaching type smoking covers, a structurally single hole wall-attaching type smoking cover 1 and branch justice smoking pipelines 2 of having increased more, make cost strengthen 25%, and it is big to exist volume, it is big to take kitchen space, globality is poor, the shortcoming of ornamental difference.The whirlwind of this patent removes tar device (Fig. 1 3) and also exists the shortcoming that volume is big, power consumption is big.

It is low that task of the present invention is to propose a cost.Volume compact, the wall type oil vapour extractor of globality and good decorative property, And make except that the tar device and reach the purpose that volume is little, power consumption is few.

Wall dual-hole oil soot extractor of the present invention (as shown in Figure 3) is by the wall-attaching type smoking cover, blower fan 7, smoke extracting tube 6, non-return valve 5, remove the tar device, start indicator lamp, compositions such as pernicious gas siren or air-sensitive automator, it is characterized in that it has a double-hole wall type smoking cover, the feature of this double-hole wall type smoking cover is: (1) smoking cover and blower fan break away from have a style of one's own (smoking cover itself is not with blower fan); (2) smoking cover is closed case; (3) smoking cover has two smoking ports; (4) smoking cover has a flue gas opening and closing device; (5) smoking cover has a closed oil collection box and pipe; (6) smoking cover has one and can hang at the erecting by overhang on the stove wall or have a frame mounting that can directly be supported on the cooking stove table top, the function of flue gas opening and closing device can guarantee the independent smoking of smoking port, also can guarantee the smoking simultaneously of two smoking ports.

The flue gas opening and closing device divides two kinds of versions: air channel, left and right sides open and close valve in (1) smoking cover cover; (2) smoking port opening and closing device.The smoking port opening and closing device need only be contained on the smoking port, also can respectively adorn one on two smoking ports.Air channel, left and right sides open and close valve is contained in outlet flue place in the cover in the smoking cover cover.Two kinds of versions of flue gas opening and closing device can be divided into some kinds of forms again, see aftermentioned for details.

The motor of blower fan can adopt double-speed motor, when two cooking stoves use simultaneously, drives top gear, when having only a cooking stove to use, opens low or first gear, to satisfy the requirement of different air quantity.Though the difference of the two kitchen range single hole wall type oil vapour extractors of it and prior art is that the latter also has an opening and closing device separately, but it need be received respectively on two smoking covers with two single hole wall-attaching type smoking covers and two smoke extracting tubes, also will increase a branch justice pipeline more.Suspension type bell-type on prior art such as the market (or claiming flat) is though the smoking cover of smoke exhaust ventilator also has two smoking ports in same smoking cover, but it does not adorn any flue gas opening and closing device, starting shooting can only be the air draughts simultaneously of two smoking ports, when only needing a cooking stove to use, another smoking port is that sky is taken out, obviously consumed one times of electric energy more, in order to economize on electricity, on two blower fans of two smoking ports, respectively adorned a switch on the product that has, when a cooking stove uses, only drive the blower fan of a smoking port, but use proof to exist very big shortcoming, because what produce in the smoking cover is malleation, when a smoking port blower fan job, flue gas just flows back in the kitchen from another idle smoking port, and the smoking cover of suspension type smoke exhaust ventilator itself is being with blower fan, volume is big, can not adherently install.

Then there is not above-mentioned disadvantage in wall dual-hole oil soot extractor of the present invention, when a cooking stove uses, closes one of them smoking port, guarantee can not suck or the gas of emerging from idle suction inlet, and motor is double speed, can only open low or first gear, to reach the purpose of economical and energy saving.

Feature of the present invention is that also said double-hole wall type smoking is covered with following four kinds of versions:

The double-hole wall type smoking cover of (1) the two two-way smoking of side, it has a closed case, its back side is vertical plane by wall, end face is a horizontal plane, press the difference of end face shape, can make the smoking cover of the two-way smoking of two sides of different shape, as the triangle cover, trapezoidal cover and arc cover, two smoking ports open respectively case two limits to declivity to the different inclined-plane of two directions of frying pan on.By two different directions smokings.Also can there be difformity on this inclined-plane, sees shown in Figure 27,28,29,30,31 embodiment.
