Definitions

  • the present invention relates to sanitary fittings according to the preamble of patent claim 1 and a method for the production of sanitary fittings according to claim 13.
  • thermocouples or mixing cartridges In order to save weight, it is known to produce water ducts separately from valve body housings, to connect these with the components that contain functional components of the valve such as thermocouples or mixing cartridges and then to provide them with a housing shell.
  • a thermostatic valve which consists of two connection blocks, one block containing the valve top and the hot water inlet and the other block contains the thermostatic element and the cold water inlet.
  • the two blocks are connected by water pipes and surrounded by an outer shell.
  • fittings consist of many items, so that the assembly costs significantly increased.
  • a mixer tap is disclosed, which can be adapted to the respective position of the water connections and their water supply is formed by the housing and at least three other components.
  • the object of the invention is to provide a sanitary fitting with low installation costs, in which the water supply can be made separately from a housing.
  • a sanitary fitting comprising a housing and a water supply module, wherein the housing has connections for a cold and a hot water supply and an outlet for mixed water, and the water supply module comprises a preformed hollow profile and at least one inlet for cold, hot or mixed water, provided in which the housing is in one piece and the water supply module is sealingly connectable to the housing. Furthermore, the water supply module may also each include an inlet for cold and hot water.
  • the receptacles for functional components namely a thermostatic element, a mixing cartridge or a valve top are provided in the water supply module and not in the housing. This simplifies the effort in producing the housing's interior.
  • a further advantageous embodiment provides that the water supply module comprises two separate water paths, wherein the one waterway surrounds the other at least partially radially. As a result, a very space-saving design can be achieved.
  • the water supply module for example, the mixed water guide, consists of a tube and inlet and outlet are respectively provided at the pipe end.
  • the water supply module is equipped with O-rings and inserted into the receptacles provided in the housing. The fixation takes place via the frictional engagement of the sealant.
  • the inlets for cold and hot water are provided on the water supply module in the radial direction.
  • the water guide module or the hollow profile is formed so that tight transitions to the connections for cold and hot water can be achieved.
  • the tubes or cylindrical hollow profiles, which make up the water supply module flattened in this area and provided for example with a groove for an O-ring.
  • the inlet for hot water on the water supply module is sealingly connected to the connection for the hot water supply to the housing.
  • the cold water enters the housing at the connection for cold water and flows around the water supply and the housing interior.
  • a so-called "cool-touch" effect is achieved, since the waterways that carry hot or warm water are not connected to the surface of the fitting, but are surrounded by cold water. Scalding the user by touching while showering or cleaning the valve are excluded.
  • the one-piece design of the housing is of great advantage, since the sealing points are reduced to the connections and the outlet.
  • the inlets for cold and hot water on the water supply module are arranged in the region of the receptacle for a thermostatic element. This means that the thermostat is located on the side of the hot water connection and the hot water is led directly from the housing connection into the thermostat area. The cold water flows around the inside of the housing and the water supply from the outside until it reaches the inlet in the thermostat area.
  • the water supply module is formed so that both the housing connection for cold water with an inlet for cold water at the water supply module and the housing connection for hot water with an inlet to the water supply module is sealingly connected.
  • the design of the water supply module further allows the outlets to be positioned at different locations so that they correspond to the mixed water outlet on the housing. This is in each case dependent on whether the mixed water, whose amount is controlled by a valve top, is guided in the inner or outer waterway. Accordingly, the outlet of the water supply module is only on the outside Waterway or at the inner waterway connected to the mixed water outlet of the housing.
  • Both plastic and metal materials can be used for the housing and / or the water-guiding module.
  • a large number of methods are currently available for shaping the hollow profiles for the water guidance module.
  • Especially for the production of the areas for receiving the functional components are offered in hollow profiles made of metal processes such as "heat forming", since in this case thin wall thicknesses and thus a lightweight and material-saving construction can be achieved.
  • the invention provides a method for the production of sanitary fittings in which first a one-piece housing for a sanitary fitting with connections for a cold and a hot water inlet and a mixed water outlet and a water supply module are made separately, the order is not relevant. Subsequently, the water supply module is inserted into the housing in such a way that during the installation process of the water supply module in the region of a connection point and in the area of the mixed water outlet, a dense composite of housing and water supply module is formed. This composite can be achieved for example by positive or non-positive connections between the housing and water supply module, each suitable sealing means are used at the connection points.
  • Fig. 1 shows a section through a sanitary fitting 1 not according to the invention, in this case a thermostatic mixer.
  • the sanitary fitting 1 has a housing 2, which consists of a cast body. This is largely cylindrical and has except the necessary openings on the jacket for hot water connection 21, cold water connection 22 and outlet 4 on the sides each have an opening 23 for a thermostatic element and an opening 24 for a shut-off valve.
  • nozzles 25, 26 are integrally formed in the cast body, which have the necessary connection geometries.
  • the passage opening tapers so that it corresponds to an inlet 34, 35 on the water supply module 3 and allows a tight connection to this.
  • the water guide module 3 consists in the present case of a two-part hollow body, the first part of which is inserted through the housing opening 23 for the thermostat and the second part through the housing opening 24 for the shut-off valve in the housing 2.
  • the water supply module 3 is divided into several areas.
  • a receptacle 6 for a thermostatic element the geometry of which corresponds to the dimensions of the thermostatic element, is followed by a cylindrical tube 33 for guiding the mixed water, which in turn ends at the inlet 51 of a receptacle for a shut-off valve 5.
  • the outlets 52 of the receptacle 5 are in turn connected to a second tube 32 which radially surrounds the first cylindrical tube 33 up to the housing outlet 4.
  • the cylindrical tube 33 for the first mixing water path is integrally connected to the receptacle 6 for the thermostatic element.
  • the jacket thickness of the cylindrical tube 33 decreases abruptly in the region of the housing outlet 4 and runs constantly up to the tube end.
  • the second part of the water guide module 3 has a substantially cylindrical shape. This is pushed from the other side of the valve 1 as a sleeve on the cylindrical tube 33 of the first mixing water path and frictionally connected in the region of the tube with the larger cladding thickness via a sealing means with this.
  • the hot water connection 21 of the housing 2 opens directly into the hot water inlet 35 of the water supply module 3, while the cold water connection 22 initially only leads into the housing interior.
  • the cold water flows around the water guide module 3 until it reaches the cold water inlet 34 on the water guide module 3, which is like the hot water inlet 35 to the receptacle 6 for the thermostatic element.
  • the mixed water leaves the receptacle 6 for the thermostatic element, passes through the first mixing water 33 to the shut-off valve, through the outlets on the receptacle 5 for the shut-off valve to the second mixing water path 32, which radially surrounds the first and flows from there to outlet 4, which in the center of the fitting 1 is located at the bottom.
  • FIGS. 3 and 4 extends the second outer waterway 32 to the receptacle 6 for the thermostatic element and is connected there with this, so that the water supply module 3 is present as a unit in one-piece form.
  • the dimensions of the water guide module 3 are chosen so that it can be pushed and mounted from one side of the housing 1 in this.
  • the water supply in the water supply module 3 is changed.
  • the inlet for the hot water 35 is provided on the outer waterway 31, which thus acts as a hot water path.
  • the hot water reaches the inlet for hot water 35 at the receptacle 6 for the thermostatic element.
  • the cold water connection 22 of the housing 1 opens directly to the receptacle 6 for the thermostatic element and is connected there directly to the inlet for cold water 34.
  • the mixed water passes through the inner waterway 33 to receive 5 for the shut-off valve and leaves the housing 1 through the outlet 4 which is provided in the region of the receptacle 5 for the shut-off valve. Since the waterways for cold and hot water do not intersect in this embodiment, the length of the fitting 1 can be shortened, resulting in a further material savings.
