Description

High-speed air type hand dryer with automatically-swinging wind direction

Technical Field

The invention relates to the technical field of hand dryers, in particular to a high-speed air type hand dryer with an automatically-swinging air direction.

Background

The high-speed air type hand dryer is characterized in that the wind speed is very high and can reach more than 130 m/s at most, the hand drying speed is within 10 s, the heating power is low and is only hundreds of watts, the heating function is only to keep the comfort level, and the hand drying speed is not influenced basically. Because the hand drying speed is high, the paper towel is popular in places such as food factories, pharmaceutical factories, electronic factories, high-end office buildings (good sound insulation effect) and the like, and because of low energy consumption, the paper towel is almost as fast as hand drying speed of paper towel, and the paper towel is recommended by environment-friendly people.

However, the high-speed air type hand dryer reduces the width of the air outlet to reduce the area of the air outlet so that the speed of the air flow rushing out becomes high, and the wet hands are washed in the form of the sheet-shaped air knife to scrape off moisture on the hands and dry the hands, so the hands must be translated by using the high-speed air type hand dryer, and the air knife is passively scraped on the hands, so the use is troublesome.

Disclosure of Invention

In summary, in order to overcome the defects of the prior art, the invention provides the high-speed air type hand dryer, the wind direction of which can automatically swing, and the hands of which can be wiped off without moving.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a but wind direction automatic swing's high-speed wind type hand dryer, includes the hand dryer main part, the hand dryer main part is equipped with air inlet and air outlet, still includes pendulous device, pendulous device includes swing head and swing mechanism, the swing head is equipped with and is greater than the air outlet duct of air outlet, swing head rotatable coupling in outside the air outlet, swing mechanism control the swing head swings, when the swing head swings the air outlet duct is located all the time the air-out within range of air outlet.

So set up, the user will wash the below of putting at the hand dryer main part of drenching both hands, infrared induction device in the hand dryer main part senses the operation behind the both hands, begin to blow off high-speed air knife in the air outlet, swing mechanism in the pendulous device begins to function, swing mechanism begins to control the swing head swing, because the air-out duct lies in the air-out within range of air outlet all the time when the swing head swings, so the air knife must blow on the air-out duct, blow off from the export that the air-out arrived under the guide of air-out duct, the both hands of drenching need not to remove the air knife and just can follow the swing head and scrape dry both hands down with water on hand, and is very convenient.

Furthermore, the hand dryer main body is provided with a swing frame, and the swing head is in rolling connection with the swing frame.

So set up, the swing head alright swing around the centre of a circle of roll connection on the swing span, the swing span supports occasionally in the swing, and the swing is more stable.

Furthermore, the swing mechanism comprises a motor, a rotary table, a rotary block and a transmission rod, the motor controls the rotary table to rotate, the rotary block is connected with the end face of the rotary table in a rolling mode, the rotary block is connected with the transmission rod in a sliding mode, and the transmission rod is connected with the swing head.

So set up, the motor drives the carousel rotation when pendulous device moves, and the relative position between the commentaries on classics piece of the terminal surface of carousel and the swing head changes during the rotation, because the terminal surface roll connection of commentaries on classics piece and carousel, the transfer line of being connected with the swing head with change piece sliding connection, so change the piece and can face the swing head all the time when rotating, the transfer line can slide under the drive of commentaries on classics piece and take the swing head to reciprocate on the swing span, simple structure.

Further, swing mechanism still includes the worm, the carousel be with the gear of worm adaptation, the hand dryer main part is equipped with the swivel mount, the carousel with the swivel mount roll connection, the worm with the motor linkage.

So set up, because the carousel be with the gear of worm adaptation, be equipped with and formed worm gear mechanism between carousel and the worm, just can drive the carousel rotatory on the swivel mount when the motor is rotatory, simple structure to adopt worm gear mechanism can reduce motor power, the motor main part also can set up in the hand dryer main part, reduces the volume of swing mechanism outside the hand dryer main part.

Furthermore, a flexible ring is arranged between the swing head and the air outlet.

So set up, the air knife that blows out in the follow air outlet just can be wrapped up by flexible circle, can not expose between air outlet and air outlet channel, and flexible circle can be connected with the air outlet of any shape, and flexible circle can warp along with the swing of swing head during the swing, can not influence the swing of swing head.

Furthermore, the oscillating device is provided with a protective cover, the protective cover faces the air outlet and the end face of the hand dryer body without an outer wall.

So set up, alright with the pendulous device parcel in the safety cover, reduce the probability that steam gets into and leads to the short circuit, because the terminal surface of safety cover towards the air outlet is not equipped with the outer wall, the transfer line can be in that side terminal surface free activity, can not receive the influence.

Furthermore, the angle of the protective cover facing the swinging head and facing away from the hand dryer body is provided with a wind-letting inclined plane.

According to the arrangement, the transmission rod is not required to be overlong to prevent the swinging head from being blocked by the protective cover when the air knife is guided to blow to the inner side, the air knife can blow outside the air inclined plane, and meanwhile, the function of the protective cover is kept, and the structure is simple.

Furthermore, the air outlet and the swing head are respectively provided with two air outlets.

So set up, two air outlets can correspond two hands, and two hand mid portion can not be bloied, has increaseed the rate of utilization of air knife, has reduced blowing out of meaningless air knife, the power saving more.

Furthermore, the transmission rod is provided with a fork head, and two ends of the fork head are respectively connected with the two swing heads.

So set up, the forked end alright in order to control two swing head swings of a transfer line, need not two swing mechanism, and can freely change arbitrary swing head.

Furthermore, the two swing heads outside the two air outlets are integrally arranged.

So set up, alright rely on a transfer line to drive two swing heads simultaneously and swing simultaneously behind two swing head integratively settings, need not two swing mechanism, simple structure.
