Description
Technical field
The present invention relates to a kind of range hoods with self-cleaning function.
Background technique
Range hood is the household electrical appliance for taking the oil smoke generated on hearth by culinary art away, but for most oil suctions
For smoke machine, a biggish problem is: the oil smoke of volatilization can be condensed in the inside of range hood, oil can with dust,
Thicker and difficult cleaning of grease is formed in body after the mixing of the impurity such as particle, after grease accumulates to a certain extent, meeting
Fine and close cured layer is formed in the inside of range hood, further increases cleaning difficulty.
Previous range hood usually requires dismantle cleaning, and some range hoods in the prior art have had
The function of self-cleaning, for example, Chinese invention patent " smoke exhaust ventilator " that Authorization Notice No. is CN103732994B (application number:
CN201280039582.3), Authorization Notice No. be CN101495814B Chinese invention patent " smoke exhaust ventilator " (application number:
) etc. CN200780027956.9 the range hood with self-cleaning function is disclosed, these range hoods are by device
Inside affix detergent container, pump, the components such as spray port, for cleaning agent to be sprayed on the portions such as blade, runner, filter screen
Part, and the raffinate after cleaning is excluded.The class formation in the prior art, spray structure are usually to stand, such structure
It can only be directed at the part of cleaned material, be difficult to cover cleaned material all surface, be easy to cause the presence at cleaning dead angle；Also have
Spray structure can be rotated by the way that power source is arranged, but since draught fan impeller itself rotates, not only resulted in this way
Structure is complicated, high production cost, and the rotation of spray structure and draught fan impeller rotation be easy to cause interference, influence cleaning effect.
Therefore, for the range hood of self-cleaning function, being improved at present up for further.
Summary of the invention
It can be charged certainly by blower the technical problem to be solved by the invention for the present situation of prior art is to provide a kind of
Machine drives spray structure to rotate and expands liquid level out to improve the range hood of cleaning effect.
The technical scheme of the invention to solve the technical problem is: a kind of fume-exhausting with self-cleaning function
Machine, including blower, the blower have spiral case and the impeller in spiral case, and the wheel nose has to connect each leaf of impeller
The assembly circle of piece, it is characterised in that: further include outlet tube, catheter and cleansing medium feed mechanism, the outlet tube is configured to
It is cyclic annular and along assembly circle, circumferentially on assembly circle, on the side wall of the outlet tube, arranged for interval has multiple prolongs into impeller
The first jet stretched, and the liquid outlet of the first jet corresponds to the blade arrangement of impeller, is connected on the outlet tube along impeller
