Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
The present invention provides the ultrasound wave of the wind wheel 7 of a kind of novel employing ultrasonic waves for cleaning range hood 5 automatic
Clean device, as it is shown in figure 1, include wind wheel 7, spiral case 6, control the controller of wind wheel motion and control
The wiper mechanism that the device signal of telecommunication connects, described wind wheel is fixed in described spiral case, and described wiper mechanism includes using
In the water injecting mechanism of water filling in spiral case 6, for discharging drainage mechanism and the controller of the water in spiral case 6
The signal of telecommunication connect supersonic generator 3, at least one be arranged at the ultrasonic transducer 4 bottom spiral case 6,
Ultrasonic transducer 4 is controlled to launch in the water in spiral case 6 for cleaning immersion water by supersonic generator 3
In the ultrasound wave at position of wind wheel.
Ultrasonic waves for cleaning is converted into high frequency oscillation by ultrasonic transducer and travels in cleanout fluid,
Ultrasound wave produces cavitation, the i.e. ultrasound wave forward directed radiation of density interphase in cleanout fluid in a liquid, makes
Liquid produces ten hundreds of minute bubbles.The negative pressuren zone that these minute bubbles are formed in ultrasound wave longitudinal propagation formed,
Growth, and at zone of positive pressure rapid closing, bubble can produce the instantaneous pressure of 1000 atmospheric pressure when Guan Bi,
Just as a series of little " blast " constantly impacts wind wheel and the surface of spiral case so that it is in surface and gap
Dirt rapid deterioration, dispersion, emulsifying, thus reach the purpose of cleaning workpiece.
Greasy dirt on wind wheel 7 is carried out by this employing ultrasound wave, regardless of the workpiece of the blower fan system in spiral case
Shape is the most complicated, as long as can be soaked in water, ultrasound wave can reach place and all can be cleaned by；And
And in liquid, the bubble of generation is highly uniform when cleaning, therefore the most consistent to the cleaning performance of work.More
Excellently, cleaning greasy dirt relative to existing cleanout fluid, if coordinating ultrasonic waves for cleaning, it can accelerate dividing of greasy dirt
From and dissolve, effectively prevent abluent to work corrosion.Therefore the wind wheel being soaked in water is used ultrasonic
Ripple cleans, and not only cleannes are high, cleaning speed fast, safe and reliable, at gap, male and fomale(M&F), deep hole also
Capable of washing totally, and to working surface not damaged, save heat energy, cleaning agent etc..
The present embodiment is preferably provided with 2 ultrasonic transducers 4, and it is evenly distributed on the bottom of spiral case 6, can accelerate
Automatically cleaning speed, improves cleaning efficiency, and makes to clean evenly, thoroughly.
Wherein, water injecting mechanism includes water pump, water inlet pipe and water-filling nozzle 1, and water-filling nozzle 1 is located on spiral case 6, water
The two ends of pump are connected with water inlet pipe and water-filling nozzle 1 respectively, and water pump is controlled water filling switch by controller.Water pump passes through
Water inlet pipe absorbs water, and is added water inside spiral case 6 by water-filling nozzle 1 the most again；Owing to the flow of water pump is relatively fixed,
Therefore controller controls the water injection time of water pump, can control water injection rate and the water yield in spiral case 6 can be soaked completely
Blade bottom bubble wind wheel 7.
Wherein, drainage mechanism includes osculum 21, drain pipe 23 and the drainage switch being positioned at bottom spiral case 6,
This drainage switch controls drain pipe and connects with osculum, i.e. drain pipe connects with spiral case, and sewage is from drain pipe 23
Discharge outside fume-exhausting body 5.Compared to using water pump suction draining, structure is simpler, and cost is lower；Phase
The sump bigger for arranging volume, more can save machine volume.And further, drainage switch is arranged
For the electromagnetic valve 22 electrically connected with the controller of range hood 5, and then this electromagnetic valve 22 is controlled work by controller
Make, make automatization clean device more automatization, intellectuality.
When cleaning is located at by the ultrasonic transducer 4 of the present embodiment, spiral case 6 is in the lateral surface at the position that is filled with water, its structure
Simply, install easily, good airproof performance, it is to avoid because of installation another in spiral case upper shed leaking of being likely to occur
Hidden danger.
It addition, in other embodiments, when ultrasonic transducer 4 can also be located at cleaning, spiral case 6 is in water holding department
The medial surface of position, i.e. ultrasonic transducer directly contacts with water, thus the ultrasonic attenuation being transmitted in water is more
Little so that ultrasonic waves for cleaning effect is more preferable.
Specifically, water injecting mechanism water filling in spiral case 6, controller controls water injection time, until water is completely soaked
Blade bottom wind wheel 7, i.e. horizontal plane L1 are located at least in the top of whole blade of the bottommost of wind wheel 1；This
Time controller start wind wheel rotate, supersonic generator work, control ultrasonic transducer 4 in spiral case 6
Water launch ultrasound wave, the most also start wind wheel 7, make wind wheel 7 slowly rotate in water, thus align be in turn
Wind wheel that is during Dong and that be soaked in water is carried out, and then completes the cleaning to whole wind wheel 7；Clean
After, controller controls wind wheel and stops operating, and controls supersonic generator and ultrasonic transducer, then
Controller controls electromagnetic valve 22 and opens osculum 21, and the sewage after being cleaned in spiral case 6 by drain pipe is discharged
Range hood 5 is external；Finally, start high-speed rotation in wind wheel 7 short time, the water on wind wheel and spiral case is got rid of
Dry.
Before opening water drainage, first close supersonic generator and wind wheel, make ultrasound wave parallel operation stop
Launch ultrasound wave, and make wind wheel stop operating, avoid the waste of the energy the most to a certain extent, reduce
The use cost of range hood.
The wind wheel rotating speed when cleaning at a slow speed is 150～250rpm, during cleaning a length of 7～15 minutes；Wind
The wheel rotating speed when high speed water dumping is 700～900rpm, during water dumping a length of 2～4 minutes.In this enforcement
In example, wind wheel preferred rotating speed when cleaning at a slow speed is 200rpm, during cleaning a length of 10 minutes, and wind wheel exists
During high speed water dumping, preferred rotating speed is 800rpm, during water dumping a length of 3 minutes.So, ultrasound wave is the most clear
The cleaning process of cleaning device more, can make wind wheel clean more thorough, and effect is more preferable, except water is more thorough, effectively
Extend the service life of wind wheel.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not office
Being limited to this, any those familiar with the art, can be easily in the technical scope that the invention discloses
The change expected or replacement, all should contain within protection scope of the present invention.Therefore, the protection of the present invention
Scope should be as the criterion with scope of the claims.
