Abstract

contraption for draining washing machine waste water by means of a hose in a sewer, characterized in that the hose (1) coming from the washing machine (2) directly or using an intermediate tube (3) with the interior of the overflow (4) of the toilet cistern (5) is connected.

Description

The Invention relates to the arrangement of the drain hose of washing machines in baths with a toilet.

To the Disposal of the waste water from washing machines in bathrooms alternatively existing outlets are used: the toilet bowl, the bathtub, a sink or a separate connection to the sewer, possibly in combination with the traps of the washbasin.

Especially the use of existing sanitary facilities has many disadvantages afflicted. For one thing disturbs the installed hose. About that In addition, the discharge of the wastewater in this way is unhygienic and demands increased Cleaning effort. For washing in the Range of 30 ° highly bacterially contaminated wastewater via the respective sanitary facility derived.

Considerations to store the washing machine wastewater and to use for toilet flushing purposes, is the subject of a number of intellectual property rights publications, without these have found significant applications. So will in the DE 40 37 389 A1 a fresh water-saving cistern described in which the rinsing process takes place in two steps. In the first step, rinsing with hot water, for example, from the washing machine and then only with fresh water. The water tank has two separate but interconnectable containers, so that the water outlet to the toilet via an outlet valve can be done with the following connecting pipe.

The Water that can not be received by the water tank flows over an overflow from the service water tank in a separate pipe in the connecting pipe fresh water container toilet.

Similarly, the service water tank works after DE 196 00 284 A1 , where excess hot water is transported via an overflow directly into the drain line of the toilet.

adversely is with these solutions the big water tank with overflow lines and separate sewer pipe connection. Furthermore, the hot water tank a bacterial collection site, since it only supplies with process water becomes.

Newer solutions (WO 03/085212 A1 or DE 203 20 782 U1 ) therefore suggest the way over a mixture of domestic and fresh water in a cistern. If one looks more closely at these solutions, a mixture only occurs in the rarest cases. If there is no hot water, only fresh water is used. On the other hand, if, for example, domestic water is supplied from the washing machine, the amount is so great that the existing fresh water in cistern drains partially and the rest at best dilutes the hot water slightly. No water at all was saved, fresh water is still polluted.

In front In this background, it is an object of the invention to provide an alternative for draining washing machine waste water via sinks and bathtubs show. It should also focus on the primary use of service water for rinsing purposes to be dispensed with in toilets.

Is solved This object with the features of claim 1, advantageous embodiments Subject of the dependent claims.

The inventive device for draining washing machine waste water by means of a hose in a sewer pipe provides that the hose for the sewage coming from the washing machine directly or using an intermediate tube with the interior of the overflow of the toilet tank connected is.

there ends when using an intermediate tube whose one end outside of the toilet cistern to connect the hose and on the other side it flows free in the overflow of the toilet cistern.

to stability should the intermediate tube or hose on the toilet cistern be fixed, preferably on a wall and / or the lid.

of course is it also possible that the intermediate tube or a portion of the intermediate tube part the wall or lid of the toilet cistern.

at Using only the hose will hose through the wall of the toilet cistern guided in the upper area. In the passage through the wall of the toilet cistern he should be fixated. Likewise, in one embodiment, that the hose at least within the toilet bowl a stabilization collar for guiding into the interior of the overflow having.

The Invention will be explained with reference to the drawing.

In the figure is a washing machine 2 shown over hose 1 to drain the waste water. Furthermore, a toilet cistern 5 shown in over an overflow 4 features. The overflow 4 is raised when rinsing, so that the Water of the toilet cistern 5 in the toilet bowl 6 can expire.

Above is the overflow 4 open, leaving the angled end of the intermediate tube 3 can open into this opening. The at the angled end of the intermediate tube 3 subsequent section is so high above the overflow 4 arranged that the movement of the overflow 4 when rinsing is not obstructed.

The intermediate pipe 3 is at the other end directly or via a connecting piece to the outside of the toilet cistern 5 led, so here's the hose 1 is connectable.

The attachment of the intermediate pipe 3 takes place on the lid and / or a wall of the toilet cistern 5 , Of course it is also possible, the intermediate tube 3 to integrate in essential sections directly into a wall or the lid. This integrated section then has a corresponding hose connection and an outlet in the overflow 4 of the toilet cistern 5 ,

In the case of a built-in wall mounted toilet cistern 5 is the connection of the hose 1 to the intermediate pipe 3 realized on an arranged on this extension to the outside of the wall.

From the washing machine 2 incoming sewage is so over the hose 1 and the intermediate pipe 3 in the overflow 4 of the toilet cistern 5 passed and flows over the toilet bowl 6 from.

This causes no or only insignificant overhead in toilet bowl cleaning and there is no annoying hose 1 more in the bathroom. A pollution of the toilet cistern 5 with lint or detergent residues is also not to be feared in this arrangement.
