Description
Technical field
The present invention relates to the self-cleaning technical field of range hood, especially a kind of self-cleaning knot of range hood impeller
Structure.
Background technology
During the use of range hood, substantial amounts of greasy dirt can be built up on impeller, strainer, these greasy dirts easily cause stifled
Plug, load increase etc., influence the using effect of range hood.As the continuous progress of range hood automatically cleaning technology, steam are clear
Wash and be widely applied in the automatically cleaning field of range hood.The basic principle of steam clean is to produce steaming by steam generator
Steam, is then delivered on the nozzle of nozzle tip by vapour, and steam quickly sprays in nozzle, washes away impeller and spiral case carries out clearly
It is clean.
For example, application publication number is the Chinese invention patent application of CN104421988A《Steam generator, cleaning system and
Range hood》(application number：CN201310377600.5), application publication number is the Chinese invention patent application of CN105436126A
《Cleaning system, a kind of range hood and its control method》(application number：CN201610009966.0 above-mentioned steam) is employed
The principle of cleaning.In existing steam clean structure, jet pipe is all fixedly mounted on spiral case close to the position of impeller, is steamed
When vapour cleans, carry out impeller rotation by crawl motor, so that steam can clean to whole impeller.There are following for such structure
Shortcoming：
(1) during motor crawl, wheel speed is too fast, can take the high-temperature steam in spiral case away, reduces temperature inside spiral case
Degree, is unfavorable for grease thawing；
(2) when wheel speed is too fast, steam continuous action is in the time just corresponding shortening of some regional area of impeller, reduction
The flushing effect of steam, influences cleaning performance；
(3) steam of nozzle can only against spiral case certain carry out jet cleaning, it is impossible to the whole inner surface of spiral case into
Row cleaning, causes cleaning performance uneven.
Therefore, for current steam clean self-cleaning structure, improved up for further.

In above-mentioned each preferred solution, the impeller is arranged in spiral case, and impeller air inlet is provided with the spiral case, should be into
A net circle is provided with air port, the sleeve is installed in the net circle by screw.
Compared with prior art, the advantage of the invention is that：The present invention is provided with driving structure in the air inlet of impeller,
The driving structure need not provide power for steam jet, and simply make the first end of steam jet easy to air inlet and have rotation certainly
By when steam sprays to impeller blade from the lower part of steam jet, since blade has certain radian, blade can pass through steam
One reaction force of steam jet is applied to, so as to promote steam jet to rotate, realizes the automatically cleaning of range hood；Meanwhile by
Rotating speed when steam jet rotates is less than the rotating speed of impeller motor crawl, and steam continuingly acts on some regional area on impeller
Time lengthen, contribute to steam effectively to wash away impeller；Also, impeller motor need not be started during steam clean, this
Sample steam would not be gone out by pump drainage so that steam can be gathered in inside spiral case, so as to lift spiral case internal temperature, contributed to
The grease of impeller and spiral case inner surface melts；Rotating steam jet drives steam to carry out 360 degree of rotating-sprays in impeller internal,
So as to effectively be cleaned to the spiral case inner surface of complete cycle, reach preferable cleaning performance.
