DE3525466A1 - WC cistern designed as a lavatory basin - Google Patents

Abstract

In order to achieve an economically and ecologically desirable reduction of the water consumption when flushing lavatories, and a reduction of the process water volume to be reprocessed without limiting the flushing quantity required for transferring sewage, the WC cistern is designed as a lavatory basin. Owing to the water which flows in to replenish the cistern being passed not directly into the reservoir but being diverted through a suitably designed and arranged fitting having a free mouth, the water can flow into the cistern via an outlet orifice arranged in the cistern cover, the water being available at the same time for washing one's hands after using the lavatory. To this end, the cover of the cistern is bowl-shaped.

Description

Description:

The invention relates to a flush water tank for toilets in the preamble of claim 1 mentioned Art.

Flushing water tanks for toilets are used to clean and flush the toilet as well as the sewage transport and thus contribute significantly to private water consumption Households at. They usually consist of a water reservoir that consists of a Feed line opening into the container and its level by a float system is regulated. When the flushing mechanism is actuated, the reservoir is emptied while at the same time water continues to run until the defined level is reached again.

Scarcity and rising cost of drinking water quality create the need to regulate water consumption in an economically sensible way. This is particularly true in view of the rising costs for the treatment of service water. Accordingly, attempts have been made by various methods to reduce the amount of water to restrict flushing the toilet.

For technical reasons, however, it is not desirable to increase the amount of water to limit when flushing the toilet, as this hinders the transport of faeces could be.

As an alternative, there is therefore the double use of the flushing water at.

The invention is therefore based on the object of a flushing water tank for toilets that allows the water intended for flushing the toilet to be used first to use for cleaning hands before the rinse tank with this water is filled. The object is achieved according to the invention by the features of the claim 1 solved.

What is new about the present invention is the shape of the container lid as a hand basin and the type of water supply that is not, as usual, direct introduced into the rinsing water tank, but by a suitably designed and arranged valve with a free opening is diverted. The control of the The filling level is carried out according to known principles, as is the triggering of the flushing activity is done with known mechanisms.

The particular advantage of the present invention lies above all in the double use of water consumption, namely 1. cleaning the hands with fresh water and 2.

Flushing the toilet with service water without any other disadvantages, such as restriction of the amount of water required to transport faeces were.

This results in a considerable, economically and ecologically desirable one Limitation of water consumption and the volume of wastewater to be treated.

Another advantage is the rationalization of the handles Use of the toilet and the promotion of hygiene.

Finally, the reduced space requirement in the toilet room is advantageous, as there is no need for an additional hand basin. The invention is therefore special useful in confined spaces.

The invention, its expedient developments in the subclaims are defined, is shown schematically below at one in the accompanying drawing The illustrated embodiment is described in detail: The whole as 1 shown, shaped as a hand basin rinsing water tank consists of the Water reservoir 2 and the container lid 3 and is at working height above the toilet bowl. The container lid is shaped as a washing trough 4 and has a by an appropriate molding non-closable drain 5, which in the rinse water reservoir flows out. The water supply leads through the non-pivotable fitting 6, the The level in the flushing water reservoir is known and not shown here Way is regulated. The trigger mechanism for flushing also takes place after known principles and is not shown.

The fitting 6 is via a suitable valve mechanism 7 with the Water pipe 8 connected. The control of this valve takes place, as mentioned, e.g. according to the known float system. The armature 6 can either be inside or outside of the rinsing water tank 1.

The wall-side part 9 of the flushing water container shaped as a hand wash basin is designed as a splash guard and can e.g. be a unit with the water reservoir 2 or the container lid 3.

The flushing water is supplied to the toilet bowl via the pipe 10.

Claims (4)

Claims: 1. Rinsing water container designed as a hand wash basin for flushing toilets, characterized in that the lid of the working height over the toilet located flushing water tank as a hand basin with a drain into the flushing water tank is shaped and that the water supply through a suitable fitting with freely opening Opening is deflected in such a way that it is possible to put the hands between the inflow and to clean the drain fitting while the level is reached after actuating the flushing mechanism is filled and regulated in the flushing water tank according to known systems. 2. rinsing water container according to claim 1, characterized in that the supply fitting with its free opening is not pivoted out of its position can be. 3. Rinsing water container according to one of the above claims, characterized in that that the drain opening cannot be closed. 4. Rinsing water container according to one of the above claims, characterized in that that the wall-side part of the lid designed as a hand basin as a splash guard serves.
