Description
Technical field
The utility model is related to smoke exhaust ventilator technology, specifically a kind of smoke exhaust ventilator free of cleaning.
Background technology
Currently on the market many smoke exhaust ventilators declare throughout one's life it is free of cleaning, the meaning free of cleaning be exactly periodically send oil network into
Row is replaced, although oil network can filter some oil smoke, oil smoke is stayed on strainer, and more oil smoke can enter snail across strainer
In shell and flue, most of oil smoke is discharged by the impeller in spiral case by flue, part oil is had during pump drainage oil smoke
Cigarette paste the channel of casing internal, the inner wall of spiral case and impeller surface, accumulating over a long period for a long time in this way will be in smoke pumping
At a thick layer of greasy dirt, the greasy dirt time of this partial coagulation has been grown can also go bad machine internal condensate and hair is smelt, or even influence
Health, and can not usually be cleaned since greasy dirt condenses on vias inner walls, spiral case inner wall and the impeller of the inside of casing body
It arrives, current most common method is exactly periodically to be professional person to tear machine cleaning open, and machine dismounting, which re-assemblies, influences whether part
The precision of cooperation can influence service life of a machine, while can also pollute kitchen in cleaning process, very inconvenient.
Someone devises smoke exhaust ventilator free of cleaning thus, and hot-water spraying's structure is internally provided in smoke exhaust ventilator, first will be hot
Water boils, by boiling water by nozzle the hot-water spraying into casing internal channel and spiral case, will be in vias inner walls and spiral case by hot water
The greasy dirt of wall dissolves, and is then discharged along flow, and this method has the effect of certain, but this structure cannot be realized fundamentally
Free of cleaning, the top and corner of channel and spiral case often are not easy to clean to, and are needed wastewater collection after cleaning, and one
As lubricating cup capacity it is inadequate, thus the structure again to casing internal is needed to be configured so that it is logical that casing internal forms water conservancy diversion
Road；Most important impeller still can not clean to simultaneously, and impeller surface condensation greasy dirt residue can aggravate motor load, to tight
Ghost image rings the pump drainage efficiency of kitchen ventilator, while also seriously affecting the service life of motor.
