Description

"Sink"

The innovation concerns a sink with a through a valve actuates the water outlet.

In the case of much-used wash basins, the handles are provided for operating the valves that control the water outlet often very spoiled. Furthermore, it often happens that one of the users does not close the valve, so that the Water runs constantly. There are already sink for public V / ash rooms known, in which to operate the Valves controlling the water outlet are provided with levers biased in the closing direction by a spring, which when in use of the wash basin must be depressed and after release a closure of the valve controlling the water outlet cause. In such arrangements, however, only one hand can be held under the water outlet.

Attempts have also been made to replace the valve arranged in the supply line to the water outlet by a valve below the To control the proximity sensor located at the water outlet,

which causes the valve to open if a user puts their hands under the water outlet. With such a Arrangement, however, there is a risk that the water will continue to run after removing the hands, because the proximity sensor remains excited by the leaking water. If there is any proximity sensor, it is located at the front of the sink there is a risk that people walking near the sink will disrupt the water supply is employed.

The innovation is based on the task of creating a wash basin in which the water outlet is automatically by means of Proximity sensor can be reliably controlled.

The task is solved by a wash basin with a water outlet which can be actuated by a valve and is characterized in that two proximity sensors are provided for controlling the valve 2, one of which is below the Water outlet on oaar behind the pool wall and the other is located on or behind the front of the pelvis.

When the hands of a user or a person approach a control circuit provided for actuating the valve controlling the water outlet, the proximity sensors supply corresponding signals. The control circuit is configured such that when not in use of the wash basin of the aageordnete at the front of the sink AssäherüBgsiiiiiler is always turned off and the below the "hate out passage arranged Annäherungsfühljr in readiness is. Now, if a user oils hands beneath the water outlet keeps ₃ provides the below of the water The proximity sensor provided sends a signal to the control circuit, which thereby signals the opening of the valve controlling the water inlet and switches off the target sensor located below the water outlet, and it senses the proximity sensor provided on the front of the pool, which has an S: spal to the

Control circuit supplies, since there is a user in front of the sink stands so that the valve remains open. If the user moves away from the sink, the one at the Proximity sensor provided on the front of the pool Signal more to the control circuit, whereby the valve controlling the water supply is closed and switches aach a predetermined delay time, during which the water in the pool can drain, the one below of the water outlet provided proximity sensor again, so that when the hands of the next user approach the the valve controlling the water supply is opened again.

The spatial arrangement of the proximity sensors in accordance with the innovation ensures perfect operation. That the valve that controls the water supply to the water outlet is automatically closed after each use. The risk of pollution has been eliminated as there are no fittings that could be touched by the hands of the user will.

The innovation will now be explained with reference to the drawings, which show a perspective view of a washbasin.

The washing corner 10 shown in the drawing has a water outlet 15 which is arranged above the basin interior lh and which is in communication with the water line via a valve (not shown). At the deepest point of Beekeninneiirauines Ik there is a drain 15, preferably below the mouth of the water outlet 15. On the rear wall of the pool interior, below the water outlet 15, there is a proximity sensor ii, in front of which a protective grille 12 is arranged, which surrounds the proximity sensor and ends with the pool surface. On the front of the basin 10, a further proximity sensor 21 is provided, which is surrounded by a protective grille 22 which is flush with the outside. The proximity sensors can also be covered
