Description

A kind of automatic hand dryer

Technical field

The utility model relates to a kind of automatic hand dryers, specifically use a kind of rotor, are rotated using rotor The moving air of generation carrys out the equipment that opponent is dried, and belongs to life machinery field.

Background technique

Main hand dryer on the market is all the form done using wind at present, and hand dryer on the market mostly uses greatly wind The blowing mode of fan formula, by prolonged use, the air inlet of this hand dryer is usually especially dirty, and bacterium grows wild.Just wash Hand, by containing a large amount of bacteriums wind drying, it 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 there is an urgent need to the equipment of a kind of clean hygiene and fast rapid-curing cutback hand.

Utility model content

In view of the above-mentioned deficiencies, the utility model provides a kind of automatic hand dryer.

The utility model is achieved through the following technical solutions: a kind of automatic hand dryer, it is characterised in that: including

Shell has opening on the shell, and user protrudes into hand in opening；

Fixed device, the fixation device installation on the inner wall of the housing, there is pulley, multiple fixations on the fixation device Device blocks rotor, so that rotor rotation；

Multiple fan blades are arranged in rotor, the rotor centre, and flabellum generates air-flow when rotating；

Inner cover, the inner cover open at one end are fixed on shell, and inside rotor, are engraved around the inner cover Sky, so that the wind that rotor generates passes through, there is opening in inner cover side, and user protrudes into hand in opening；

Power device, the power device are mounted on shell, and the power device is connected with rotor, band turn Kinetoplast rotation.

There is evenly distributed fan blades inside the rotor, the normal of circle a at an angle in fan blades and rotor, 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, is only had on half region on the outside of inner cover and is pulled aerofoil.

The aerofoil of pulling is cambered plate, air-flow effectively can be imported inner cover.

There is calandria on the inner cover, calandria is in each and pulls between aerofoil, can effectively heat air.

The hand dryer further includes having brush, and the brush is fixed on shell, on brush one end and rotor Annular opening contacts, the water that rotor is thrown away are wiped down.

There is leakage hole in the shell lower end, and the water in hand dryer can be flowed out by the leakage hole.

Flexible bar in the power device, power device are connect by flexible link with rotor, and flexible link can prevent Only because of the fracture for the bar that power device is connect with rotor caused by the high-speed rotation of rotor.

The usefulness of the utility model is to pull aerofoil to direct wind into inner cover, and opponent is dried；Outside inner cover Side half pulls aerofoil, and half does not have, and does not pull between the part of aerofoil and fan blades there are relatively large distance, can be avoided fan blades it Between pressure reduce so that air more preferably flows；Rotor high-speed rotation drives inner air flowing, reduces external bacterium；Inner cover Hollow out, not by the injury of rotor when making to go smoothly in internal gas flow.

Specific embodiment

A kind of automatic hand dryer, including shell 1 have opening 101 on the shell 1, and hand is protruded into opening 101 by user It is interior；Fixed device 2, the fixation device 2 are mounted on shell 1, there is pulley, multiple fixed dresses on the fixation device 2 It sets 2 and blocks rotor 3, so that 3 rotation of rotor；Multiple fan blades 301, flabellum is arranged among the rotor 3 in rotor 3 Air-flow is generated when 301 rotation；Inner cover 4, the inner cover 4 is fixed on shell 1, and inside rotor 3, described is interior 4 surrounding hollow outs are covered, so that the wind that rotor generates passes through, there is opening in 4 side of inner cover, and user protrudes into hand in opening；Power dress 5 are set, the power device 5 is connected with rotor 3, and rotor 3 is driven to rotate.

There is evenly distributed fan blades 301 inside the rotor 3, the normal of circle is in certain in fan blades 301 and rotor 3 Angle a, 0 < a < 70, so that rotor generates biggish 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 spherical shape, be also possible to cylindricality, and similar structure can generate identical effect.

The hand dryer further includes having brush 7, and the brush 7 is fixed on shell 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 leakage hole 102 in 1 lower end of shell, and the water in hand dryer can be flowed out by the leakage hole 102.

Flexible bar 501 in the power device 5, power device 5 are connect by flexible link 501 with rotor 3, flexible Bar 501 can prevent the fracture because of the bar that power device 5 is connect with rotor 3 caused by the high-speed rotation of rotor 3.

Aerofoil 402 is pulled on the outside of the inner cover 4, only has on the outside of inner cover 4 and 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 between fan blades 301 is avoided to reduce, so that air more preferably flows.

The aerofoil 402 of pulling is a kind of cambered plate, air-flow effectively can be imported inner cover 4.

There is calandria 401 on the inner cover 4, the calandria is mounted on inner cover 4, is specifically mounted on each It pulls between 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 heater.

When being worked, controller 6 controls all parts work, and user is protruded into hand in inner cover 4 by opening 101, Sense element senses on controller 6 are in one's hands, and controller 6 controls the drive rotor 3 of power device 5 and rotates at this time, and 3 turns of rotor The air of the raw flowing of movable property, 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 shell, and water is led down to shell 1 bottom, housing bottom have leakage hole 102, water are exported.

For the ordinary skill in the art, introduction according to the present utility model is not departing from the utility model Principle and spirit in the case where, the changes, modifications that are carried out to embodiment, replacement and variant still fall within the utility model Within protection scope.
