Description

Separating kitchen ventilator

The invention belongs to kitchen utensils.

Prior art, the inventor has applied for a " wall type oil vapour extractor " utility model patent (application number: 912030240 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, uses simultaneously as two cooking stoves, then must adopt two kitchen range single hole wall type oil vapour extractors of being made up of side by side 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, and family kitchen arranges that a picture workshop is difficult to see, mismatch very much with living circumstance, the whirlwind of this patent removes tar device (Fig. 1 3) and also exists the shortcoming that volume is big, power consumption is big.

Main purpose of the present invention is to provide a kind of cost low, volume compact, and the separating kitchen ventilator of globality and good decorative property, secondary objective of the present invention is to provide the oil expeller that a kind of volume is little, power consumption is few.

Purpose of the present invention can reach by following measure:

The invention provides a kind of separating kitchen ventilator (as shown in Figure 3), it comprises blower fan, smoke extracting tube, smoking cover and flue, described smoking cover is to separate separately with blower fan to become one, described smoking cover is connected with blower fan by smoke extracting tube, and oil expeller also is housed in flue, it is characterized in that:

1) described smoking cover is closed smoking cover;

2) 2 smoking ports are arranged on the described smoking cover;

3) be provided with the flue gas opening and closing device in the flue of described smoking cover;

4) a vertical kitchen cabinet is arranged on the end face of described smoking cover, there is flue vertical kitchen cabinet the inside, and the flue of this flue lower end and described smoking cover is connected, and a pipe is arranged on the kitchen cabinet, is provided with the thermal insulation board that the condiment product that prevents in the kitchen cabinet is crossed thermal metamorphism in the kitchen cabinet.

The flue gas opening and closing device divides two kinds of versions: 1) left and right sides flue open and close valve in the 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.Left and right sides flue 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-attaching type smoke extractors of it and prior art is that the latter also has an opening and closing device separately, 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 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 separating kitchen ventilator 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 smoking is covered with following four kinds of versions:

1) smoking cover of the two-way smoking of two sides, 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 respectively case two side direction declivities 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.

2) smoking cover of the two-way smoking of forward side direction it a closed case is arranged, look from the side, be similar to a right angle triangle or a right-angled trapezium, its back side is vertical plane by wall, end face is a horizontal plane, the end face shape can be rectangle, square, trapezoidal, fan-shaped, single-arc shaped, two arc or double flute shape, hypotenuse partly is the forward inclined-plane, it is downwards near tiltedly facing toward frying pan, the forward smoking port is opened on this forward inclined-plane, tiltedly face toward the frying pan of a cooking stove from facing down, the side direction smoking port is driveed on the side, from the side to the frying pan of declivity facing to another cooking stove.By two two-way smokings of different directions, can there be different shape on the forward inclined-plane, sees shown in Figure 27,28,29,31 embodiment.

3) smoking cover of positive smoking in the same way it a closed case is arranged, look from the side, be similar to a right angled triangle or right-angled trapezium, its back side is vertical plane by wall, end face is a horizontal plane, the end face shape can be rectangle, square, trapezoidal, fan-shaped and single-arc shaped as shown in the Examples, two arc or double flute shape, the inclined-plane partly is the forward inclined-plane, it is downwards near tiltedly to frying pan, two smoking ports are by same direction smoking, different shape can be made in the forward inclined-plane, shown in Figure 27,28,29,30,31 embodiment.

4) bottom surface in the same way smoking smoking cover it the closed case of 6 bodies of a flat box formula is arranged, the shape of end face can be rectangle, square, trapezoidal, fan-shaped, oval and single-arc shaped as shown in the Examples, two arc or double flute shape.Its bottom surface is a horizontal plane, or keeps 3-8 degree gradient, and tar flow in the closed oil collection box in the cover to guarantee to make, and two smoking ports are all opened on this same bottom surface, and two smoking ports of frying pan that face a cooking stove separately downwards are by same direction smoking.

The feature of above-mentioned 4 kinds of smoking covers also is also can add the flaring that compiles flue gas together on (or on its one side, two limits, three limits) on the periphery on the plane at smoking port place.In order further to improve the smoking effect, also can be in left and right two sides of smoking cover, left, right, front and rear four sides, or left and right, back three sides respectively add a gas collection cover plate.

On inclined-plane, smoking port place outer surface, also can add oil guide groove and open type oil collection box outside.

Itself with the characteristics of the split type smoking cover of blower fan is not: because of its volume little, the plane at smoking port place can be contained in from the very near place of frying pan, distance is near, draft is big, this is its advantage, but distance is too near, cause that easily the smoking cover shell often generates heat, cause the shell painted surface aging, relatively more complete suitable setting height(from bottom) is advisable with 300 millimeter, distance is nearer if require to smoke, can on smoking cover, add the heat dissipating housing that has the cross-ventilation interlayer one by one, promptly outside the smoking port inclined-plane, add a cover plate again, leave a fixed gap between it and the inclined-plane, smoking port place to form the interlayer of cross-ventilation heat radiation, two side seals close about this interlayer, flow from bottom to up with forced air, do not made left and right sides bleeder and go out and reduce radiating effect, a smoking mouth mask that matches with the smoking cover smoking port is also arranged on the heat dissipating housing, interlayer and smoking cover smoking port are separated, in order to avoid the convection current air is inhaled in the smoking cover in the interlayer.Heat dissipating housing can be movable detachable, also can be fixed, and the benefit of movable detachable is that the heat radiation cover plate can be taken off at any time so that take and washes surface and oil contaminant in the pond better.
