Now oil suction cigarette device generally adopts the way of unpicking and washing parts or complete machine to remove grease and the incrustation that adheres on cavity inner wall, blower fan leaf, the wheel both at home and abroad, the shortcoming of this method is: grease, incrustation are not invaded nowhere, defect such as initiation oil dripping, leakage of oil, fan blade is unbalance, noise increases difficulty to be turned down, artificial cleaning is indispensable, the cutter spatula digs and adds solution, and is not only dirty but also tired time-consuming.Other has a kind of range hood employing that oil smoke is carried out the water filtration treating apparatus, and device is complicated, also easily causes secondary pollution.

The utility model provides the sticking device of paying and avoiding incrustation to form of grease in a kind of automatic elimination body.

The utility model is to reduce capillary principle of grease and corresponding structure according to heat in closed housing and the chamber from whirlwind for achieving the above object, removes the formation of grease adhesion and incrustation.Its technical scheme is as follows:

Air inlet at existing pump drainage oil smoke main air blower is provided with a controllable gate (1), controllable gate (1) but manual unlocking also can draw through stay cord, pulley (3) changed course to panel rotary switch (4), is opened along controllable gate upper edge axle.When opening door, rotary switch (4) is also with the main air blower power supply opening.After the culinary art air inlet controllable gate is closed.Be provided with pneumatic door (6) at air outlet, its duty is with air inlet controllable gate (1).On the body internal chamber wall, (generally go to the bottom) and install a heating plate (5), are subjected to its heating power, heat time heating time the silicon-controlled voltage regulation adjusting respectively and controlled by time control switch at the chamber wall.

The principle that the new construction device is eliminated chamber wall, fan blade, the adhesion of wind axis grease is:

After each culinary art, close air inlet (pneumatic door this moment (6) is closed voluntarily), cavity is closed attitude.Opening main air blower makes its low-speed running form in the chamber from whirlwind.Because what closed housing produced presses less than atmospheric pressure in whirlwind.Gu Jinfengkoumen (1) is firm with (6) locking of pneumatic door, connect the heating plate power supply, be subjected to the heater heat temperature raising and make the intensification of also constantly being heated of chamber wall fan blade, wind wheel from whirlwind in the not excessive cavity, condensation is sticking pays about grease temperature rise to 30 ℃, surface tension promptly descends rapidly and produces molten stream, become the molten streams of small grain attitude to about 40 ℃, at the bottom of the inflow chamber in the store oil box.Grease on the fan blade is more because of action of centrifugal force, and is no longer residual.

The principle that the utility model can be eliminated incrustation is:

Only about 1 hour, then reach more than 20 hour down time to general family expenses oily fume exhauster darg.Normally closed air inlet controllable gate (1), pneumatic door (6) have been arranged, airborne dust, fiber are just no longer in more than 20 hour every day, constantly invade in the cavity because of Brownian movement and to deposit, (with a bed bottom ash dirt deposition principle: the air disturbance is more little, and deposition velocities such as dust are fast more.) cover mutually layer by layer with the sticking grease of paying, form the cutter spatula and dig the incrustation that is difficult to remove.In time heating can be eliminated the cold doubtful grease on chamber wall, leaf, the wheel automatically, also is the factor that the utility model incrustation is difficult to generate, and stickingly pays incrustation and disappears mutually each other.

Owing to taked technique scheme, eliminated grease automatically and paid body inwall, leaf, the sticking of wheel, and incrustation.
