Description
Technical field
The present invention relates to a kind of range hoods with self-cleaning function.
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.In addition, above two structure can only also clean strainer, and in the use process of range hood
In, many greasy dirts are also inevitably accumulated on spiral case inner wall and impeller, it, also can be serious if these greasy dirts are removed not in time
Fan performance is influenced, mist extractor ability is caused to decline.
Summary of the invention
It is straight by cleansing medium that the technical problem to be solved by the invention for the present situation of prior art is to provide a kind of energy
Connect the range hood with self-cleaning function for rinsing and removing greasy dirt on blower and strainer.
The technical scheme of the invention to solve the technical problem is: a kind of fume-exhausting with self-cleaning function
Machine, including shell and blower, the blower are set in shell and have spiral case, impeller and motor, the air inlet of the blower
It is provided with strainer, it is characterised in that: the output axial direction strainer direction of the motor extends and is formed with gap between strainer, institute
State the clutch for being provided on blower and the output shaft of strainer and motor capable of being made to connect or separate；It further include cleansing medium supply machine
The water outlet of structure and jet pipe, the cleansing medium feed mechanism is connected with the first end of jet pipe, the second end pair of the jet pipe
It should be arranged in the leading flank of strainer.
In the above scheme, the clutch include the first clutch cover, the second clutch cover and solenoid valve, described first
