Description
Technical field
The present invention relates to a kind of automatic hand dryers, specifically employ a kind of rotor, are rotated and generated using rotor
Moving air carry out the equipment that opponent is dried, belong to life machinery field.
Background technology
Main hand dryer on the market is all to employ the form that wind is done at present, and hand dryer on the market uses wind mostly
The blowing mode of fan formula, by much time using, the air inlet of this hand dryer is usually especially dirty, and bacterium grows wild.Just wash
Hand, the drying of the wind by containing a large amount of bacteriums is in fact very dirty on hand, only do not see.In hospital etc. pair
Under conditions of hygienic requirements is particularly severe, this hand dryer undoubtedly leads to the raising of patient's infection risk.It does not solve on the market
The hand dryer of this problem, so the equipment there is an urgent need to a kind of clean hygiene and fast rapid-curing cutback hand.
Invention content
For above-mentioned deficiency, the present invention provides a kind of automatic hand dryers.
The present invention is achieved by the following technical solutions：A kind of automatic hand dryer, it is characterised in that：Including
Housing has opening on the housing, and user stretches into hand in opening；
Fixing device, the fixing device are mounted on inner walls, have pulley, multiple fixing devices in the fixing device
Block rotor so that rotor rotation；
Rotor, rotor centre set multiple fan blades, and flabellum generates air-flow when rotating；
Inner cover, the inner cover open at one end are fixed on housing, and inside rotor, hollow out around the inner cover,
So that the wind that rotor generates passes through, there is opening in inner cover side, and user stretches into hand in opening；
Power plant, the power plant are mounted on housing, and the power plant is connected with rotor, drive rotor
Rotation.
There is evenly distributed fan blades inside the rotor, the normal of fan blades and circle on rotor a at an angle, 0
〈a〈70。
The radius of gyration maximum of the rotor has a circle circular hole, and the water droplet in user hand is on rotor, water quilt
Rotor is thrown away by circular hole.
Aerofoil is pulled on the outside of the inner cover, only has on the outside of inner cover on half region and pulls aerofoil.
The aerofoil of pulling is cambered plate, can air-flow effectively be imported inner cover.
There is calandria on the inner cover, calandria is in each between pulling aerofoil, can effectively heat air.
The hand dryer has further included brush, and the brush is fixed on housing, on brush one end and rotor
Annular opening contacts wipe down the water that rotor is thrown away.
There is a leakage hole in the housing lower end, and the water in hand dryer can be flowed out by the leakage hole.
Flexible bar in the power plant, power plant are connect by flexible link with rotor, and flexible link can prevent
Only because of the fracture of bar that power plant is connect with rotor caused by the high-speed rotation of rotor.
The usefulness of the invention is to pull aerofoil to direct wind into inner cover, and opponent is dried；One on the outside of inner cover
Aerofoil is partly pulled, half does not have, and does not pull between the part of aerofoil and fan blades that there are relatively large distances, can avoid pressing between fan blades
It is strong to reduce so that air more preferably flows；Rotor high-speed rotation drives inner air flowing, reduces external bacterium；Inner cover hollow out,
It is not injured when making to go smoothly in internal gas flow by rotor.

Specific embodiment
A kind of automatic hand dryer including housing 1, there is opening 101 on the housing 1, hand is stretched into opening 101 by user
It is interior；Fixing device 2, the fixing device 2 are mounted on housing 1, there is pulley, multiple fixed dresses in the fixing device 2
It puts 2 and blocks rotor 3 so that 3 rotation of rotor；Rotor 3,3 centre of rotor set multiple fan blades 301, flabellum
Air-flow is generated during 301 rotation；Inner cover 4, the inner cover 4 is fixed on housing 1, and inside rotor 3, described is interior
Cover 4 surrounding hollow outs so that the wind that rotor generates passes through, and there is opening in 4 side of inner cover, and user stretches into hand in opening；Power fills
5 are put, the power plant 5 is connected with rotor 3, and rotor 3 is driven to rotate.
There is evenly distributed fan blades 301 inside the rotor 3, fan blades 301 is with normal round on rotor 3 in certain
Angle a, 0 ＜ a ＜ 70 so that rotor generates larger air quantity.
The radius of gyration maximum of the rotor 3 has a circle circular hole 302, the water droplet in user hand on rotor,
Water is rotated body and is thrown away by circular hole 302.
The rotor 3 can be that spherical or cylindricality, similar structure can generate identical effect.
The hand dryer has further included brush 7, and the brush 7 is fixed on housing 1,7 one end of brush and rotor 3
On circular hole 302 contact, the water that rotor 3 is thrown away is wiped down.
There is a leakage hole 102 in 1 lower end of housing, and the water in hand dryer can be flowed out by the leakage hole 102.
Flexible bar 501 in the power plant 5, power plant 5 are connect by flexible link 501 with rotor 3, flexible
Bar 501 can be prevented because of the fracture of bar that power plant 5 is connect with rotor 3 caused by the high-speed rotation of rotor 3.
Aerofoil 402 is pulled in 4 outside of inner cover, and 4 outside of inner cover, which only has, pulls aerofoil 402 on half region, outside inner cover 4
Side half pulls aerofoil 402, and half does not have, and does not pull between the part of aerofoil 402 and fan blades 301 that there are relatively large distances, can
Pressure reduces between avoiding fan blades 301 so that air more preferably flows.
The aerofoil 402 of pulling is a kind of cambered plate, can air-flow effectively be imported inner cover 4.
There is calandria 401 on the inner cover 4, the calandria is mounted on inner cover 4, specifically mounted on each
Between pulling aerofoil 402, air-flow takes away the heat on calandria 401 when passing through inner cover 4, promotes the temperature of air, increases comfortable
Feel and accelerate the speed of dry hand.
The calandria 401 is PTC heaters.
When being worked, controller 6 controls all parts work, and user is stretched into hand in inner cover 4 by opening 101,
Sense element senses on controller 6 are in one's hands, and controller 6 controls power plant 5 that rotor 3 is driven to rotate at this time, 3 turns of rotor
The air of movable property life flowing, air-flow encounter on inner cover 4 when pulling aerofoil 402, carry over and pull aerofoil 402 and flow to inside inner cover 4, simultaneously
The calandria 401 pulled between aerofoil 402 heats air, and hot-air dries up water on hand.
To on rotor 3 under water droplet in user hand, since rotor 3 rotates, water overcomes centripetal force by rotor 3
Circular hole 302 flow out, by under the water brush outside rotor 3, brush 7 tilts down the brush 7 on housing, and water is led down to housing
1 bottom, housing bottom have leakage hole 102, water are exported.
For the ordinary skill in the art, introduction according to the present invention, do not depart from the principle of the present invention with
In the case of spirit, the changes, modifications, replacement and the modification that are carried out to embodiment still fall within protection scope of the present invention it
It is interior.
