Abstract

The invention concerns a water pipe branching device for filling a toilet tank (15) derived from an on-off tap (20) for supplying, before it is introduced in the tank, a hand-washing equipment basin (3), using an actuator-dispenser (1), connected on the tank and on the water spraying column (22) provided with an antipollution sealing device (26 or 33), with flexible pipes (14 and 18). The system which operates automatically without manual intervention is particularly designed for limiting risks of bacterial transmission and for saving water.

Description

DEVICE FOR AUTOMATICALLY SUPPLYING WATER TO A BATHROOM

The invention relates to a device for supplying drinking water to an anti-pollution water spraying column fixed to a washbasin in a lavatory, by means of a flush / flush valve actuated by a float. In the known processes of this type, the water supply of hand-washing is performed by means ^of a bleed valve controlled by a float, this valve, which does not protect from pollution the drained pipe is placed in the outside or inside the tank, a location that requires the presence of a hole on the side or on the cover of the tank to pass the water supply hose to the hand basin, the hose must be separated from the drain hose . In another method, the tank cover is transformed into a hand basin, a solution which requires manufacturing a tank to adapt the flush control device to the side of this tank.

Drilling a hole in the earthenware manufacture ^of a drain tap or manufacture of a tank with an incorporated hand-washing, impose cost price that can compete with the price of washing hands for the current trade attract customers concerned with hygiene and water savings.

The present invention consists in remedying these drawbacks and in tackling the problem of bacterial transmission during the use of taps in lavatories. The accompanying drawings illustrate the invention: FIG. 1 of plate 1 represents the view of the entire device. -2-

On board 2, FIG. 2 represents the removable grid for emptying the basin, FIG. 3 represents the fixing screw and the dispersion grid on which the disinfection product rests, FIG. 4 represents the O-ring of the tank , Figure 5 shows the drain tank viewed from above, with its T-shaped tube, Figure 6 shows the drain tank seen from the side.

On the board 3, Figures 7 and 8 show the emission shutter of the projection of ^water column with the inlet channel of ^water released and blocked by the ball (33) .On the board 4, Figures 9 and 10 show another ^device for emission control valve consists of a valve (26) rocking on a pivot (27) to occlude the spout (25) of the water column (22).

The device according to the invention is produced by means of a distributor fixed below the basin of the hand basin. This distributor comprises a tank for recovering and draining the ^water used or not (1) of a pipe T-shaped (10) introduced into the wall of the vessel, and two coaxial pipes. A small diameter pipe (18) connects a tap gives / cup of ^drinking water under pressure (20) controlled by the float (21) with a projection antipollution water column (22) fixed on the washbasin (3) hand basin.

A second pipe of larger diameter, is divided into two pieces (14 -14b) which are fixed on each of the ends (13) and (13b) of the horizontal part of the T-tube (10), the part (14) connecting the drain pan (1) of washing hands with the reservoir of ^flushing (15) the portion (14b) connecting the orifice of the overflow (17) with the reservoir (15) through the portion horizontal T-tube (10). -_ -

The water spray column (22) is provided with an antipollution shutter (32) consisting of a ball or a cone (33) placed in a cage (34) which frees the water spray channel ( 35) under the pressure of ^water from the flush ^water valve (20). For the purpose of prevention against pollution this ball or the sealing cone falls and obstructs the water discharge channel (35) when ^the water supply pressure is

cut.

By another method the sealing is performed on the spout (25) of the projection column (22) by means ^of a valve (26) which is raised under the pressure of ^water by tilting on a pivot (27) . After repelling ^one or other of the emission shutter devices (26) or (33) of the projection of water column (22) water, used or not, projected into the basin of the washing hands (3) enters the recovery tank and drain (1) of the splitter to be directed, as any water from the orifice of the overflow (17) in the flush cistern (15) ^by connection port (16) by means ^of a coaxial pipe of larger diameter (14 and 14b) wherein, inside the tank, engages in a connecting block (28) which allows the water used to flow to fill the reservoir (15) through an orifice (31) formed on one of its faces. On another of its surfaces an orifice (30) is designed to allow the ^introduction of the small pipe (18).

The device operates as follows when the user operates the ^flush, ^water in the tank (15) flows and the float (21) falls and actuates the tap gives / cup (20) opens and automatically feeds the water spray column (22) via a small diameter coaxial supply pipe (18). -4-

At the end of filling of the tank, by means of the coaxial pipe (14), the float (21), which has followed the rise in the level of water in the tank (15), actuates the tap gives / cuts (20) which cuts off the supply of drinking water, which automatically suppresses the supply of water to the projection column (22). In this device the small diameter water supply pipe (18) is introduced over the entire length inside diameter large drain pipe (14-14b), the thus assembled pipes, ^drinking water rises , in a sense, in the projection column of ^water through the pipe (18) and this water used or not, descends in the opposite direction into the reservoir (15) through the tube ( 14). The disinfection product is easily introduced into its filtration housing (36) by lifting the removable filtration grid (6) from the basin (3), the housing being screwed into the device with the screw (5)

This device, in one of his achievements is fixed under the sink washing hands placed in the ^permanent toilet in any place available, its installation requires no costly intervention or the use of ^a tap or no connection by means of conventional pipelines since it may be connected to a flushing ^water tank by means of two flexible coaxial pipes.

The present invention relates on the one hand, public health that the lack of hand-washing in a closet, or even the presence ^of a hand wash provided with ^a manually operated valve, are potential sources of bacterial transmissions and on the other hand, water economy in that ^an amount ^of recoverable water discharged directly into the sewer is detrimental in view of the shortage of drinking water and therefore of its high price.
