Description
Technical field
The present invention relates to one kind can carry out the self-cleaning range hood of strainer.
Background technique
In recent years, people's lives level is continuously improved, and health and environmental consciousness are increasingly enhanced, and people thirst for possessing one
Health, cleaning, environmentally friendly family kitchen environment.Chinese patent CN200710051289 discloses a kind of air dust centrifugal clarification
The production method of device and its rotary filter net disk, rotary filter net disk are arranged by Dropbox skeleton and edge circumferencial direction uniform winding
Radial radiation shape strainer is constituted.Above-mentioned filter screen plate is entwined by a strainer silk, and production method is many and diverse, and strainer silk is easy corruption
Eating off is split, and strainer silk intensively interlocks in Dropbox central region, is caused oil smoke windage big and oil smoke unsmooth flowing obstruction strainer, is made
Oil smoke efficiency must be separated to be reduced quickly, service life serious curtailment.
To solve the above-mentioned problems, Authorization Notice No. is a kind of Chinese utility model patent " turn of CN 204285570U
Centrifugal fume separator " (application number: 201420732722.1) disclose a kind of structure comprising rotation Dropbox and wind wheel,
Rotation Dropbox is mounted on wind wheel air inlet, rotate the edge of Dropbox and wind wheel front ring edge connect or rotate Dropbox center and
Wind wheel center be connected or rotation Dropbox and wind wheel front ring it is integrally formed.
Above two structure can realize fume purifying to a certain extent, still, in use, adhere to it
Grease is removed naturally by centrifugal action, and obstinate grease is still inevitably adhered to after long-time use, into
And influence its strainability.
Summary of the invention
Soaking and washing side can be passed through the technical problem to be solved by the invention for the present situation of prior art is to provide a kind of
The greasy dirt that formula removal is adsorbed on strainer is to realize the range hood of self-cleaning effect.
The technical scheme of the invention to solve the technical problem is: one kind can carry out the self-cleaning fume-exhausting of strainer
Machine, including exhaust fume collecting hood and blower, the blower are set in exhaust fume collecting hood, it is characterised in that: the air inlet mouth down arrangement of the blower,
The washing tube to hold cleaning solution is provided with below the air inlet, being provided between the air inlet and washing tube can open
Or the strainer collapsed, it is covered on air inlet under the strainer opening state, is protruded into washing tube under the strainer rounding state.
In the above scheme, the motor output shaft of the blower is vertically arranged, and the motor that the strainer is set to blower exports
It can open on axis and under fan operation state, be collapsed under blower run-stopping status.Strainer of the invention utilizes blower certainly
The centrifugal action of translator, which is realized, to be opened or collapses, and when motor operation, strainer is opened, and when motor is out of service, strainer is collapsed.
Preferably, the strainer includes the first assembly set, the second assembly set and support bar, the first assembly set is fixed
It is placed on motor output shaft and is arranged close to air inlet, the second assembly set can be nested with moving back and forth along motor output shaft
In on motor output shaft and positioned at the first assembly set lower section, the lower rotational of the support bar first end is connected to the second assembly set
On, the top of the support bar first end is rotationally connected with the first assembly and puts on, and the support bar is provided in the longitudinal direction
The long hole of cooperation can be oriented to the first assembly set in the case where the second assembly set moves down state.Using the above structure, in blower
Under motor operating state, support bar is moved down with the second assembly set under the action of the centrifugal force and is opened, to make strainer by wind
The air inlet of machine covers, and plays a role in filtering；Under the motor run-stopping status of blower, the second assembly set is covered to the first assembly
Close, support bar collapses simultaneously and in lower end insertion washing tube, is convenient for soaking and washing.
In order to which just with assembly, described first, which fills matched periphery, is provided with the first buck plate arranged in regular polygon, should
Each edge of first buck plate is provided with the first connecting shaft, and the support bar is that the long hole on a plurality of and each support bar passes through
Corresponding first connecting shaft arrangement.
In order to which just with assembly, described second, which fills matched periphery, is provided with the second assembly corresponding with the first buck plate
Plate, each edge of second buck plate are provided with the second connecting shaft corresponding with the first connecting shaft, the support bar first
The lower hinge at end is in second connecting shaft.
Preferably, the lower surface of the support bar first end is downwardly extending auxiliary section of the projection on support bar,
The axis hole for being equipped with and passing through for the second connecting shaft is provided on the auxiliary section.
In above-mentioned each preferred embodiment, the strainer further includes strainer item, the strainer item be more and arranged for interval in
Between each support bar.It is provided with the structure, the setting quantity of support bar can be reduced, and improves filter effect.
As an improvement, the first end of the strainer item is connected in the first end of support bar by connecting line, the strainer
The elastic component that all strainer items can be made to keep gathering trend is connected in the second end of item, which passes through the second of support bar
End.Above-mentioned elastic component is preferably the spring of annular, and setting above structure can be such that strainer item collapses by the elastic force of spring, and to branch
Stay plays the role of assisting gathering, to make strainer is whole quickly to collapse.
Preferably, the internal diameter of the washing tube is gradually increased from bottom to top.Using the structure, on the one hand collapsed convenient for strainer
And be inserted into washing tube, on the other hand, narrow wide structure narrows the runner in exhaust fume collecting hood gradually under washing tube, can into
The oil smoke for entering exhaust fume collecting hood is rectified, and using Venturi effect, so that oil smoke flow velocity is inversely proportional with flow section, flow velocity gradually increases
Greatly, meanwhile, meeting Bernoulli's theorem, the increase of oil smoke flow velocity can enhance the negative pressure in exhaust fume collecting hood with the reduction of Fluid pressure,
Enhance the suction-operated to oil smoke.
For the ease of installation, columnar assembly cover is provided in the exhaust fume collecting hood, the upper port of the assembly cover is connected to
On the outer edge of the air inlet, the lower port of the assembly cover constitutes the air inlet of exhaust fume collecting hood, and the washing tube passes through branch
Frame is installed on the internal perisporium of the assembly cover.
Compared with the prior art, the advantages of the present invention are as follows: the air inlet mouth down arrangement of blower in the present invention, so that
There is biggish accommodating space, to install the strainer that can be opened or collapse, the present invention is also provided with below strainer in exhaust fume collecting hood
To hold the washing tube of cleaning solution, when fume-exhausting operation, oil smoke is filtered using open strainer, works as fume-exhausting
When machine is out of service, strainer can be collapsed and be immersed in washing tube, to be impregnated, be washed to the oil smoke adhered on strainer
It washs, strainer is made to remain cleaning, realize the self-cleaning effect of strainer, to improve filtering oil smoke effect.
