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 that a certain extent oil smoke is net
Change, still, in use, the grease adhered to it is removed naturally by centrifugal action, after long-time use still
Obstinate grease is so inevitably adhered to, and then influences its strainability.
Be arranged the self-cleaning mechanism of cleansing medium can be sprayed into spiral case can be to the greasy dirt accumulated on spiral case inner wall and impeller
Cleaning removal is carried out, the cleaning effect being easy to get, however, people are in use, be difficult to whether know spare cleansing medium
Using finish or whether excessive addition, it is inconvenient for use.
Summary of the invention
It can control cleansing medium the technical problem to be solved by the invention for the present situation of prior art is to provide one kind to add
Dosage and be the range hood with self-cleaning function that user brings convenience.
The technical scheme of the invention to solve the technical problem is: a kind of fume-exhausting with self-cleaning function
