Abstract

A hand drier in box form comprises a U-shaped deep groove (5) slant arranged at inner upper part thereof and having air nozzles (2) arranged at both inner walls of the opening thereof; a water drainage hole (51) opened at bottom thereof; and a high speed blower (7) and a water receiver (8) arranged at inner lower part thereof; wherein an air outlet of the blower (7) is provided with an air channel (9) communicated with the air nozzles (2) at the U-shaped deep groove inner walls, a water tube (6) has both ends respectively communicating the water drainage hole (51)at the U-shaped grove bottom with the water receiver (8). The utility model utilizes high pressure air flow to remove mist attached on wet hand skin, requires no heat source, rapidly dries hands within several seconds, has low energy consumption, only targets hands inserted into the U-shaped groove to avoid influencing other part of the human body, and can simultaneously collect the removed water inside the device, which is hygienic.

Description

A kind of hand dryer

The utility model relates to a kind of hand dryer.

Hand dryer generally all is installed in the toilet of public arenas such as hotel, restaurant, existing hand dryer all is the hot blast type, be to be provided with an electric calorifie installation and a blowing device in the machine, its air outlet down, when the user washes hand, the hand that speckles with foam is stretched under the air outlet, under manually or automatically controlling, hand dryer is started working, and blows out soft hot blast foam is on hand brushed, evaporates.There is such defective in this hand dryer: the one, because the hot blast that blows out of hand dryer is directly to setting about, so its temperature can not be too high, make hand just longer from wet exsiccation required time; The 2nd, because hand dryer is to blow out hot blast down, and hot-air is lighter, can upwards flow, and therefore can involve other zones of human body, and this can bring certain discomfort to the people, particularly when temperature is higher; The 3rd, water droplet on hand can be dropped on the ground, is damp all the time thereby can make the ground under the hand dryer; The 4th, the electric calorifie installation in the hand dryer can consume a large amount of electric energy.

The purpose of this utility model provides a kind of quick hand dryer of low energy consumption that does not adopt thermal source with regard to being at above-mentioned prior art present situation.

Another purpose of the present utility model is to provide a kind of the hand dryer that can not influence other positions of health at the work of staff position.

Another purpose of the present utility model is to provide a kind of hand dryer of the water of drippage on hand of collecting.

The purpose of this utility model is achieved in that hand dryer integral body is the box type, and its internal upper part has the U moldeed depth groove of an oblique setting, and two walls are provided with fumarole in the inboard of its opening part, has osculum in its bottom; Bottom is provided with a high-speed fan and a water spilage tray in it, and the air outlet of blower fan has the air channel to be connected with the fumarole of inboard two walls of U type groove; The two ends of one water pipe are connected the osculum of U type trench bottom respectively with water spilage tray.

The inboard two wall fumaroles at described U type channel opening place are good with several spouts and word order, to form the gas curtain that one expelling water foam used; Described U type groove can be provided with infrared detector at the inboard of its opening part two walls.

Compared with prior art, the utility model utilizes the principle of air fluid mechanics, adopts high pressure draught to remove and is attached to the foam on wet skin of hand surface, and need not to adopt thermal source, can be in the several seconds fast rapid-curing cutback hand, have the characteristics of energy saving of low energy consumption again; Because opening is up, and institute's gaseous blast is slightly downward, therefore, can not influence other positions of health only at the staff position work of stretching in the U type groove, the foam of being blown down simultaneously directly is collected in machine intimate, clean hygiene again.

Description of drawings.

Fig. 1 is the stereoscopic schematic diagram of the utility model embodiment.

Fig. 2 is the structure cross-sectional schematic of the utility model embodiment.

Fig. 3 is the A-A cutaway view of Fig. 2.

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 3, hand dryer integral body is the box type, its internal upper part has the U moldeed depth groove 5 of an oblique setting, be provided with the fumarole 2 of several relative word orders at the inboard of its opening part two walls, be respectively arranged with

infrared detector

1,4 in the above and below of fumarole and stretch into or leave to detect hand, the bottom of U moldeed depth groove 5 has osculum 51:

Lower position in hand dryer is provided with a high-speed fan 7 and a water spilage tray 8, and the air outlet of blower fan 7 has air channel 9 to be connected with the fumarole 2 of U type groove 5 inboard two walls, and air inlet is arranged on the below of hand dryer; The two ends of one water pipe 6 are connected the osculum 51 of U type trench bottom respectively with water spilage tray 8.

For reducing noise, inwall also is provided with several noise abatement liners 10 in described connection air channel.3 is indicator among the figure.

During use, when wet hand stretches into U moldeed depth groove 5, upper track infrared detector 1 at first detects signal, indicator 3 sends information, remind the user to continue hand is stretched into bottom land, after wet hand reaches bottom land, following road infrared detector 4 detects signal, the machine internal controller is just opened blower fan 7 automatically, make blower fan fast turn-around, output high pressure draught through air channel 9 spout 2 from both sides spouting in U type groove 5, form air curtain one, air blast is brushing the surface of moist skin, and when slow with one's hands when extracting out in U type groove 5 slowly, the gas curtain of porch resembles the scraper of one softness, will be attached to arm, the palm, the foam of position skin surfaces such as finger scrapes in the U type groove 5, the ponding of wandering bottom land connects water pipe 6 drainages through machine and is collected in the drip tray 8, so that handle; When hand left U type groove 5, upper track infrared photoelectric detector 1 detected signal once more, and the machine internal controller is promptly controlled machine time-delay operation just autostop after 1 second.
