Description

The present invention relates to a wall connection for connecting a sanitary fitting to a water network, with a wall-side, an inlet channel having connection part and a fitting side, an outlet channel having connection part, wherein the inlet channel and the outlet channel are arranged eccentrically offset from one another. Such wall connections are also known as S-connections.

A wall connection with the aforementioned features is for example made DE 196 51 313 C2 known. As far as such wall connections are also connected to the hot water line of the water network, the high temperatures of the hot water lead even with closed sanitary fitting due to the heat conduction through the wall connection to an increase in the temperature of the wall connection and ultimately to an increase in the temperature of the connected to the wall connection sanitary fitting. If a thermostatic valve is used as a sanitary fitting, the heat conduction heats the water in the thermostatic valve. This increase in temperature and the associated expansion of the expansion element of the thermostatic valve cause the thermostatic valve could be damaged. Out DE 20 2012 012 816 U1 is therefore known, for example, to thermally decouple the fitting-side connection part of the wall connection with respect to the sanitary fitting. For this purpose, a heat-insulating element is to be arranged between the dashboard-side end face of the connection part and the end face of the sanitary fitting. In addition, the union nut is thermally insulated from the sanitary fitting. Although this arrangement leads to a reduction of the water temperature in the sanitary fitting with a closed sanitary fitting, a further reduction of the temperature would be desirable. Moreover, since the heat insulation element between the end face of the sanitary fitting and the end face of the connection part is fixed only during the installation of the sanitary fitting, it is not always ensured that the installation of this heat insulation element during installation also takes place.

The object of the present invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide a wall connection which thermally decouples the water network from a sanitary fitting connected to the wall connection and ensures that the heat insulation is mounted ,

This object is achieved by a wall connection with the features of the independent claim. Advantageous developments of the wall connection are specified in the dependent claims and in the description, wherein individual features of the advantageous developments in a technologically meaningful way can be combined with each other.

The object is achieved in particular by a wall connection with the features mentioned, in which the wall-side connection part and the fitting-side connection part are formed as separate components, wherein the one connecting part is arranged with an engagement portion in a socket portion of the other connection part and at least one heat insulating element formed in the axial direction and in the radial direction between the engaging portion and the female portion, wherein at least one of these heat insulating elements cooperates with a shape of the engagement portion and a shape of the female portion so that the female portion and the engaging portion alone secured by the one heat insulating member against an axial relative displacement are.

The invention thus has the advantage that due to the axial and radial arrangement of the heat insulation elements thermal decoupling is given by the wall connection between the water network and sanitary fitting. In addition, a heat insulating element has a double function, by being used for the one hand for the thermal decoupling and on the other for the secure connection of the wall-side connection part with the fitting-side connection part of the wall connection. Since an assembly of the wall connection can be made only with the heat insulating element, it is ensured that the heat insulating element is present. Since the wall connection is preassembled, it is not necessary to mount the wall connection at the installation site, so that it is also ensured that all heat insulation elements are present.

The two connection parts each have a connection section, with which they are connected to the water network or to the sanitary fitting. Opposite the terminal portion, the terminal parts have either a female portion or an engaging portion. The bushing section is in particular cup-shaped, with the engagement section of the other connecting part being arranged inside the bushing section.

The wall connection may comprise one or more heat insulation elements, wherein in particular a heat insulation element is arranged partially or completely between the end face of the engagement section and the bottom of the socket section and another Heat insulating member or the same heat insulating member radially surrounds the engaging portion in the circumferential direction.

The one or more heat-insulating elements also has the function of mechanically connecting the wall-side connection part and the fitting-side connection part to one another. For this purpose, both the inside of the socket portion and the outer side of the engagement portion is formed so that a non-positive and / or positive connection between the socket portion and the engagement portion is made via a heat insulating element. The wall connection is delivered as a preassembled unit, which preferably can not be disassembled without special tools.

The shape of the bushing section is in particular an internal thread which cooperates with an external thread on the thermal insulation element which mediates the mechanical connection.

The shape of the engagement portion is in particular a radial projection on which the mechanical connection mediating thermal insulation element is supported in the axial direction. In addition, since the engaging portion can be secured against rotation in the heat-insulating member providing the mechanical connection, the engaging portion can be mounted in the female portion at the same time as the heat-insulating member is screwed into the female portion.

In a simple embodiment, the heat-insulating element that mediates the mechanical connection is annular and surrounds the engagement section, wherein it bears against a side wall of the bushing section. In this case, a second heat insulating member is disc-shaped with a central hole and disposed between an end face of the engaging portion and a bottom of the bottom portion. On the disk-shaped heat insulation element, a cylindrical projection extending in the axial direction can be formed on the hole side, which engages in the engagement section for centering.

In order to improve the sealing function in such a two-part embodiment of the heat insulation, a gasket is disposed in a circumferential gap radially bounded by the engagement portion and the bushing portion and axially bounded by the first heat insulation member and the second heat insulation member.

In particular, a silencer is arranged in the outlet channel of the fitting-side connection part.

The invention and the technical environment are explained below by way of example with reference to FIGS. It show schematically

The in the 1 and 2 illustrated embodiment of a wall connection according to the invention 1 includes a wall-side connector 2 with an entrance channel 3 which is used to connect to a water network. The wall-side connection part 2 has a bushing section 7 in which a fitting-side connection part 4 with an engaging portion 6 is arranged. The fitting side connection part 4 serves to connect to a sanitary fitting and has an outlet channel 5 on. In the exit channel 5 is a known silencer 18 arranged. The entrance channel 3 and the exit channel 5 are arranged eccentrically offset from one another.

Between a wall-side connector 2 facing end face 14 of the engaging portion 6 and a floor 15 of the socket section 7 is a second heat insulating element 9 designated perforated disc made of a plastic. The second heat insulation element 9 thus ensures a thermal decoupling of the connection parts 2 . 4 in the axial direction.

In addition, an annular heat insulating element 8th provided that the engagement section 6 the fitting side connector 4 surrounds. On its outside, the heat insulation element 8th an external thread 11 on, with it in a on a side wall 13 of the socket section 7 the wall-side connection part 2 trained internal thread 10 is screwed. Since the engagement section 6 a radial projection 12 having, behind the screwed-in thermal insulation element 8th engages are the connecting parts 2 . 4 secured against a relative displacement to each other. The heat insulation element 8th thus has two functions. On the one hand, it secures the connection parts 2 . 4 against a relative displacement and on the other hand it ensures a thermal insulation.

In addition, the wall connection 1 a seal 16 on that in a crack 17 is arranged, both from the heat insulation elements 8th . 9 as well as from the engagement section 6 and the socket section 7 is limited. In addition, the wall connection 1 partly from a delusion 19 surround.
