Abstract

Device for washing, rinsing, disinfecting and drying one's hands automatically. The invention relates to a device for hygiene of the hands. It consists of a double body the outer face (1) the inner face is perforated at the base for the outflow of the water (2), a fan sends hot air (10), the hot air rises back up towards the fan in order to be recycled (13) dropping of liquid soap (7) water (6) disinfectant (8), lamp illuminating the inside (12) with its glass window (17), fan locking the hot air inside, and the splashes of water (9), contactor (switch) (11) spacer (15), outflow of water (16).

Description

 The present invention aims to allow to perform er (thanks to a single device) the various operations necessary for washing hands, this in the best conditions of comfort and hygiene, without any manipulation.

 Until now, the different phases of this kind of spraying, wetting of the hands, coating with soap, rinsing and drying with a cloth or warm air, required steps and various means or utensils located in different places. although very close. (sink, towel, or hot air blower system).

 The system now avoids these procedures by bringing them together at the same point on a single device.

 This device essentially consists of two tanks, metallic or plastic, one exterior (1) the other interior (2) the latter provided with perforations on its lower half circumference. These two tanks positioned one inside another on a horizontal axis, raised by 305 in order to facilitate the evacuation of the waste water.

 These two concentric tanks are made integral by four bolts (15) on the rear part of the assembly, each of these two tanks being closed by a cover making oflice of facade (3) the sealing is obtained by neoprene seals (16 ) This facade is provided with an opening (4) to allow the user to introduce his hands inside the central tank.

To operate this device requires
- the electricity supplied by a connection to the E.DF sector
- water supplied by a connection to the urban network.

 - drainage of waste water.

 The liquid soap and sanitizing product can be supplied by connecting specially adapted small tanks fitted with a drain opening provided with a quick snap which can be adapted to the pipes permanently fixed on the upper part of the device.

 Figures (2 and 3) show in section the relative position of the two tanks and the system for supplying water, soap and other products.

On the upper part of the external tank (1) there is the assembly (5) device which, by crossing the two tanks (1 and 2) ensures by a pipe (6) the arrival of water then by a tube more small (7) that of liquid soap, a
other small tube (8) being provided for possibly delivering
er sanitizing products.

The triggering of the device and the different phas
its washing is provided for a predetermined period and cont
can be controlled by a timer, thanks to a fixed switch (11)
in the axis of these tanks, on the internal face of the internal tank
(The complete cycle is sixty seconds).

The user just has to press this switch
easily identifiable because it is luminous, so that the device
walking you.

The operation takes place in the light
projected through a window on the upper part
of the two tanks, by a lamp (12) whose support is
attached to the outside.

The turbine (9) blows a curtain of ambient air at the front
iant in front of the opening (4). This air flow being intended
reduce water and hot air projections to the esters
with tanks. Another turbine (10) blows at the end of the cycle
the a stream of hot air for drying the hands, this air
after passing into the inner tank (2) escapes
by holes made in the lower part, then is
taken up by a permanent recycling guided by a deflector
(13) to the nozzle (14) and returned to the circuit again
in the lower tank.

 A mobile version on a tripod or quadripod stand, provided with a wheel, in which case the power supply can be done by a 12-volt battery or electric extension, the water supply by a tank located at the top of the device and the evacuation of waste water, by a residual tank located in the lower part of the device.

 The front of these tanks is made of a transparent plastic material or of metallic bodywork.

 A cleaning of the internal face of the inner tank is provided, which cleaning will be carried out by a sweep obtained by an arm articulated on a horizontal axis.

 The small volume of the device and its relatively reduced weight allows it to be fixed to a wall or to be embedded in the same wall. It is planned to start the cycle, washing, rinsing, drying by breaking a spoke as soon as the hands are inserted inside the device.

Claims (5)

CLAIM 9  1. Device for washing hands without any manipulation, characterized  by a mobile version mounted on a tripod or quadripod stand, fitted with a wheel,  in which case the electricity supply can be done by a 12-volt battery or  electrical extension, water supply from a tank located at the  upper part of the appliance and waste water discharge, through a residual tank located  in the lower part of the device or an evacuation in natural terrain.  2. Device according to claim (1) characterized in that the facade of these tanks is  made of a transparent plastic material, this set can be presented without  metallic bodywork or plastic economy version. 3. Device according to claim (1) characterized, there is provided a cleaning of the face  internal of the inner tank, which cleaning will be carried out by a sweep  obtained by an arm articulated on a horizontal axis. 4. Device according to claim (1) characterized in that the small volume of  the device and its relatively reduced weight allows it to be fixed to a wall or its  recess in this same wall. 5. Device according to claim (1) characterized, it is  provided for starting the cycle, washing, rinsing, drying  by the rupture of a ray upon the introduction of the hands to  inside the appliance.
