Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 3, the unpicking and washing-free range hood comprises:
a casing 100 provided with a smoke inlet passage 110;
the volute 200 is arranged above the inner part of the machine shell 100, the top of the volute 200 is provided with a smoke outlet 210, the front side of the volute 200 is provided with a smoke inlet 220 communicated with the smoke inlet channel 110, the bottom of the volute 200 is provided with a conical oil guide hole 230, and the conical oil guide hole 230 has a better oil gathering effect;
a fan 300 including an impeller 310 installed in the scroll casing 200 and a motor 320 for driving the impeller 310 to rotate;
the oil guide bracket 400 includes an inclined downward oil guide plate 410, the oil guide plate 410 is located below the oil guide hole 230, side baffles 420 respectively extend upward and vertically along the left and right sides of the oil guide plate 410, the upper ends of the two side baffles 420 respectively extend outward to form flange portions 430, and the oil guide bracket 400 is connected with the scroll casing 200 through the two flange portions 430.
When the range hood starts the self-cleaning function, the fan 300 performs oil throwing according to a preset program to throw oil on the impeller 310 out of the volute 200 and liquefy the oil into liquid oil, then the oil drops to the oil guide bracket 400 through the bottom of the volute 200 under the action of gravity, and finally flows out to a preset oil discharge area along the oil guide plate 410, so that the oil is guided to be away from the fan 300 to prevent the oil from being atomized again and contaminating the impeller 310. This lampblack absorber lead oily rational in infrastructure, lead oily oil extraction effect good, and lead two side shield 420 on the oily support 400 and can prevent that the greasy dirt from breaking away from and lead oily orbit, effectively avoid the greasy dirt to the secondary pollution of lampblack absorber, lampblack absorber automatically cleaning effect ideal.
It is worth mentioning that the surface of the impeller 310 is coated with a nano hydrophobic oil-repellent layer to reduce the oil residue on the surface of the impeller 310 and improve the oil throwing effect of the impeller 310. The surface coating of the impeller 310 may also be other oil-proof coatings, such as those cited in the background art, in which the oil-proof coating is made of teflon coated varnished cloth compounded with glass by thermal shrinkage.
The flange portion 430 of the oil guide support 400 is provided with the long circular hole 431 in the left-right direction, so that the installation position between the oil guide support 400 and the volute 200 can be conveniently adjusted, and the oil guide support 400 is more labor-saving to install and debug.
Wherein, the bottom of the rear side of the casing 100 is installed with a long strip-shaped oil cup 500, and the front end of the oil guide plate 410 is higher than the rear end thereof and extends backwards to above the oil cup 500. Under the action of gravity, the oil stains can be separated from the oil guide plate 410 and directly dropped into the oil cup 500, and finally, the user can intensively treat the oil stains through the oil cup 500.
Preferably, the oil deflection plate 410 extends forwardly out of the volute 200. When the fan 300 works, part of the oil mist can be contaminated to the front side wall of the volute 200 and liquefied into liquid oil dirt, and the oil dirt can be gathered to the bottom of the volute 200 under the action of gravity, the oil guide plate 410 extends forwards out of the volute 200, the part of the oil dirt can be collected and guided to the oil cup 500, and the oil guide effect is better.
Further, a front baffle 440 vertically extends upward from the front end of the oil guide plate 410. Oil guide support 400 can effectively prevent the greasy dirt of lateral wall before spiral case 200 from breaking away from the oil guide orbit through setting up preceding baffle 440, effectively avoids the greasy dirt to the secondary pollution of lampblack absorber, and lampblack absorber self-cleaning effect is ideal.
The rear sidewall of the casing 100 protrudes forward to form an oil return plate 120 inclined downward, the front end of the oil return plate 120 is located below the scroll casing 200, and the front end of the oil return plate 120 does not exceed the oil cup 500. Similarly, when the fan 300 works, part of the oil mist can be contaminated to the rear side wall of the volute 200 and liquefied to form liquid oil stain, the part of the oil stain can be guided to the oil cup 500 through the oil guide bracket 400, and the liquefied oil stain contaminated to the rear side wall of the casing 100 can be directly guided to the oil cup 500 through the oil return plate 120, so that the oil discharge and guide effect inside the range hood is further improved.
In order to further reduce the oil stain residue on the surface of the impeller 310, a plurality of blades 311 with arc-shaped sections are uniformly distributed on the circumference of the impeller 310, and the cross sections of the blades 311 are arranged in a fish scale shape. The impeller 310 of the structure utilizes the principle of the fish scale veins, improves the oil throwing effect of the impeller 310, can also generate larger air volume, and has low noise.
The control circuit board 600 is installed on the top of the casing 100, the control panel 700 is installed on the front side of the casing 100, and the control circuit board 600 is electrically connected with the motor 320 and the control panel 700 and controls the motor 320 to operate according to a preset program.
This lampblack absorber provides a self-cleaning step of confession reference, specifically as follows:
1. the range hood is started by touching the control panel 700 lightly, and works normally;
2. when the range hood is operated for 20 hours in an accumulated mode, the self-cleaning key indicator lamp of the control panel 700 flickers once a second when the range hood is shut down, and at the moment, the automatic self-cleaning function can be started through the control panel 700 or the prompt is closed to restart timing and remind;
3. when the self-cleaning function is started, the motor 320 starts to clockwise drive the impeller 310 to rotate at a high speed for 1 minute, after the impeller is suspended for 5 seconds, the impeller is rotated at a high speed for 1 minute again, the three circulation cleaning is finished in sequence, the accumulated running time is cleared, and the timer is restarted.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
