Description

The invention relates to an exhaust pipe Boiling water device, the evaporation pipe a first Double bend between its connection on Has boiling water device and its spout and on its connection is pivotable about a first axis.

Boiling water devices with such steam pipes are known in the market. The steam pipe also serves as Overflow pipe in the event that the user Water inlet fitting not before the tank is full of the boiling water heater closes. The steam pipe is swiveling, depending on the installation situation To be able to swivel the sink. However, it has shown that in particular by the known steam pipe such mounting situations are difficult to master, where a modern, round sink is provided.

In GB 928 372 there is a boiling water device described. In this is the cold water inlet pipe with connected to a flexible connecting hose. For the Exhaust steam a valve is provided at the top of the storage tank.

The object of the invention is to provide an exhaust pipe to propose the type mentioned at the beginning, the different its connection closer or farther Allows swivel positions of its outlet.

According to the invention, the above object is for an exhaust pipe of the type mentioned in that the Steam pipe has a second double bend and that  the second double bend about one to the first axis parallel second axis is pivotable.

This gives you the opportunity to phase out the Steam pipe in the most varied of installation situations in to bring a suitable swivel position, considerably expanded. Even with round sinks bring the spout over the sink. He let position itself so that it is the water outlet of the tap close.

Often in the water connection pipe Boiling water device or its tap Shut-off valve for the water connection of a dishwasher or a washing machine. Another advantage the invention is that as a result of Variable adjustability of the steam pipe leaves that it does not operate the shut-off valve with special needs.

In a preferred embodiment of the invention, the first double bend the water connection of the Boiling water device or its tap. This is the same on the right and left of the tap fitting Given swivel range.

In an embodiment of the invention, the distance is second axis from the first axis smaller than that Distance of the second axis from the outlet. This is on the one hand, a wide swivel range is possible. On the other hand, it is also achieved that the evaporation pipe Operability of the tap does not interfere.

Further advantageous embodiments of the invention result from the subclaims and the following Description of an embodiment. In the drawing demonstrate:

Fig. 2, the exhaust pipe on a boiling water heater with tap fitting,

Fig. 3 shows a plan along the line III-III of Fig. 2,

Fig. 4, the steam pipe with tap fitting and shut-off valve and

Fig. 5 is a plan view in the direction of line VV in FIG. 4.

An evaporation pipe ( 1 ) has a first pipe section ( 2 ) and a second pipe section ( 3 ). The first pipe section ( 2 ) and the second pipe section ( 3 ) are each provided with a double bend ( 4 ) and ( 5 ).

The first pipe section ( 2 ) forms a connection ( 6 ) with which it can be plugged into a connection piece of the boiling water device ( 7 ). For this it has expressions ( 8 ). The pipe section ( 2 ) can be pivoted on the boiling water device ( 7 ) about a first, vertical axis (A1).

A vertical leg ( 10 ) of the second pipe section ( 3 ) is pushed over a vertical leg ( 9 ) of the pipe section ( 2 ). Mutual stops ( 11 ) are formed on the legs ( 9 , 10 ). Formations ( 12 ) are designed between these, which ensure that the pipe section ( 3 ) is pivotally held on the pipe section ( 2 ). The pipe section ( 3 ) can be pivoted about a second axis (A2) around the first pipe section ( 2 ). The axes (A1, A2) run parallel to each other.

The second pipe section ( 3 ) forms an outlet ( 13 ) which is inclined at a small angle to the vertical.

The distance (L1) of the second axis (A2) from the first axis (A1) is smaller than the distance (L2) of the second axis (A2) from the outlet ( 13 ).

At the bottom of the boiling water device ( 7 ) there is a tap ( 14 ) with a curved water outlet ( 15 ). The tap ( 14 ) can be connected to the water network via a water connection ( 16 ) and leads via a pipe section ( 17 ) into the water reservoir of the boiling water device ( 7 ). The connection ( 6 ) of the first pipe section ( 2 ) is located centrally behind the pipe section ( 17 ) (cf. FIG. 3). This engages with its double bend ( 4 ) around the water connection piece ( 16 ).

The total length of the vertical legs ( 9 , 10 ) is dimensioned such that the second pipe section ( 3 ) can be swiveled through under the water outlet ( 15 ) (cf. FIG. 2).

The tap fitting ( 14 ) has three adjusting handles ( 18 , 19 , 20 ) which are used to tap cold water, let cold water into the boiling water device ( 7 ) or tap hot water from the boiling water device ( 7 ).

In the position of the pipe section ( 2 ) shown with a solid line in FIG. 3, when the second pipe section ( 3 ) is pivoted about the axis (A2), the smallest pivoting range (a) is obtained (see FIG. 3, FIG. 5). . In Fig. 3, the first pipe section ( 2 ) is to the left of the water connection piece ( 16 ). If it is turned to the right, the smallest swivel range (b) for the outlet ( 13 ) results.

If the second pipe section ( 3 ) is pivoted from its position shown by the solid line in FIG. 3 to the left, approximately into its dashed position, then the largest pivoting range (c) results. This can be extended to the front if the first pipe section ( 2 ) is pivoted about the axis (A1) into its position shown in broken lines in FIG. 3. When the first pipe section ( 2 ) is moved to the right, the largest swivel range (d) can be reached on the right side. The smallest swiveling range (a, b) could be reduced by swiveling the first pipe section ( 2 ) backwards. The outlet ( 13 ) of the second pipe section ( 3 ) can be brought into all positions that lie between the smallest swivel range (a, b) and the largest swivel range (c, d).

In the application example according to FIGS. 4 and 5, a shut-off valve ( 21 ) is arranged on the water connection piece ( 16 ) and is connected to a washing machine or a dishwasher via a line ( 22 ). The evaporation pipe ( 1 ) can be adjusted in its smallest pivoting range (a) and in its largest pivoting range (c) without its vertical legs ( 9 , 10 ) hindering the actuation of the shut-off valve ( 21 ), since the vertical legs ( 9 , 10 ) run on the side of the water connection piece ( 16 ) opposite the handle ( 23 ) of the shut-off valve ( 21 ).

The evaporation pipe ( 1 ) can be designed so that its second pipe section ( 3 ) can be rotated more easily about the second axis (A2) than its first pipe section ( 2 ) about the axis (A1). If it is desired that the outlet ( 13 ) is fixed in a selected position, a latching or locking can be provided.
