CN203757805U - Split type range hood - Google Patents

Abstract

The utility model relates to a split type range hood which comprises an inner machine and an outer machine, wherein the inner machine is connected with the outer machine through a negative-pressure resistant aluminum foil flue pipe and a circuit; a power supply of the range hood is switched on by a switch on the inner machine for driving a motor in the outer machine; the outer machine further comprises a fan. The power supply of the range hood is switched on by the switch on the inner machine for driving the motor in the outer machine, so that the motor can rotate at high speed; a wind wheel rotates to generate negative pressure in the flue pipe, so that an air negative pressure region is formed within a certain space range above a stove and before an oil net of the outer machine, and indoor air and oil fume gas are sucked into the range hood together; the oil fume gas is filtered by the oil net to be subjected to primary oil fume separation; then the oil fume gas enters the outer machine of the range hood through a connection pipe to be subjected to secondary oil fume separation through rotation of a turbine; oil fog in the oil fume in an air cabinet is condensed into oil drops under the action of centrifugal force, and the oil drops are collected into an oil cup below the outer machine through an oil path; purified flue gas is discharged into air through an air return prevention cover.

Description

Seperating cooker hood

Technical field

The utility model relates to seperating cooker hood.

Background technology

The principle of all smoke extractors all in the market: connect range hood power supply, drive motors, make wind wheel make High Rotation Speed, make to form air negative pressure district in the certain spatial dimension in cooking stove top, indoor air is sucked to range hood together with soot gas inner, soot gas filters through oil network, carry out oil smoke separation for the first time, then enter cigarette machine air channel inner, rotation by turbine is carried out secondary oil smoke separation to soot gas, oil smoke in wind cabinet is subject to the effect of centrifugal force, mist of oil is aggregated into oil droplet, by oil circuit, collect in the lubricating cup of cigarette machine below, flue gas after purification is finally discharged along fixing smoke pipe.

There is in design very large drawback in current cigarette machine, a lot of producers are in order to promote cigarette machine smoking effect, blindly increase power of motor, cause " the cigarette machine wind that smoking effect is better is made an uproar larger " smoking effect to make an uproar into direct ratio with wind, the effect of the satisfaction reaching very much.

The cleaning of lampblack absorber is also a pretty troublesome thing, a lot of people think, and the machine surface that can see and the screen pack wash clean easily unpicked and washed is just passable, in fact be substantially equal to like that not wash, because what cigarette machine needed most cleaning is the obstinate greasy dirt that the oil smoke on wind wheel accumulates over a long period, otherwise more collection is more, the more and more heavier motor load of wind wheel is more next large, and last motor burns out.A lot of families are unwilling to wash, but do not know how to wash, and look for professional's cleaning of visiting, and not only payment for a piece of handwork valency is high, and it is dirty not necessarily just to find this not to be afraid of, the master worker who is not afraid of toil.Up to the present the cleaning service of cigarette machine be provided without any a brand, most of family selections " the less trouble the better, to really can not be with renewing again ".

Utility model content

For a modern kitchen, range hood has very important effect, for addressing the above problem, the utility model designs that a energy consumption is low, noise is little, the lampblack absorber of easy to clean, and for future, the development of modern kitchen has very important effect.

The utility model provides a kind of seperating cooker hood, and described range hood is divided into interior machine and two parts of outer machine, and the aluminium foil smoke pipe by anti-negative pressure between interior machine and outer machine is connected with circuit;

The power supply of the switch connection range hood on described interior machine, drives the motor in outer machine;

In outer machine, further comprise blower fan.

Power supply by the switch connection range hood on interior machine, drive the motor in outer machine, make motor High Rotation Speed, wind wheel rotates to allow in smoke pipe and forms negative pressure, make before inner engine oil net, within the scope of the certain space of cooking stove top, form air negative pressure district, indoor air is sucked to lampblack absorber together with soot gas inner, soot gas filters through oil network, carry out oil smoke separation for the first time, then by tube connector, enter the outer machine of cigarette machine, rotation by turbine is carried out oil smoke separation for the second time to oil smoke, oil smoke in wind cabinet is subject to the effect of centrifugal force, mist of oil is aggregated into oil droplet, by oil circuit, collect in the lubricating cup of outer machine below, flue gas after purification is discharged in air by anti-air-return cover.

The advantage of maximum of the present invention is divided into interior machine, two parts of outer machine a range hood exactly, and the motor, the wind wheel that easily produce noise are installed in outer machine, is placed on outdoorly, so just can greatly reduce in kitchen because the noise producing during range hood running.

For at present a lot of buildings, outer machine is installed and is had certain risk, comprise that a lot of buildings have adopted common set smoke pipe, it is outdoor impossible merely outer machine to be contained in, at this moment invented simultaneously outer machine can have been hung over to the outer machine on ceiling, the air outlet of outer machine is directly aimed to the air inlet of common flue, the noise of outer machine will be reduced greatly by the isolation of ceiling.

Accompanying drawing explanation

By describing in more detail exemplary embodiment of the present utility model with reference to accompanying drawing, above and other aspect of the present utility model and advantage will become and more be readily clear of, in the accompanying drawings:

Fig. 1 is the structural representation of seperating cooker hood of the present utility model.

The specific embodiment

Hereinafter, now with reference to accompanying drawing, the utility model is described more fully, various embodiment shown in the drawings.Yet the utility model can be implemented in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, it will be thorough with completely providing these embodiment to make the disclosure, and scope of the present utility model is conveyed to those skilled in the art fully.

Hereinafter, exemplary embodiment of the present utility model is described with reference to the accompanying drawings in more detail.

With reference to accompanying drawing 1, a kind of seperating cooker hood, described range hood is divided into interior machine 1 and 2 two parts of outer machine, and the aluminium foil smoke pipe 3 by anti-negative pressure between interior machine 1 and outer machine 2 is connected with circuit (Fig. 1 is not shown).Power supply by the switch connection range hood on interior machine, drive the motor 5 in outer machine, make motor High Rotation Speed, wind wheel 6 rotates to allow in smoke pipe and forms negative pressure, make before inner engine oil net, within the scope of the certain space of cooking stove top, form air negative pressure district, indoor air is sucked to lampblack absorber together with soot gas inner, soot gas filters through oil network, carry out oil smoke separation for the first time, then by tube connector, enter the outer machine of cigarette machine, rotation by turbine is carried out oil smoke separation for the second time to oil smoke, oil smoke in wind cabinet is subject to the effect of centrifugal force, mist of oil is aggregated into oil droplet, by oil circuit, collect in the lubricating cup of outer machine below, flue gas after purification is discharged in air by anti-air-return cover.Between outer machine and exterior wall, there is beam 7, for alleviating the damage of the vibrations of outer machine to body.
