Definitions
- Sanitary fittings have a fitting housing in which the actual valve devices are housed. It is already known to design the actual valve devices, for example a mixing valve, as a cartridge, which is then inserted into a receiving space in the fitting housing which is adapted to the cartridge.
- the manufacture of valve housings made of cast iron is very complex and leads to heavy housings.
- valve housings from sheet metal. But even in this case, a receptacle for the cartridge is installed in the manufacture of the valve body.
- the invention has for its object to improve and simplify the manufacture and assembly of sanitary fittings.
- the invention proposes a sanitary fitting with the features of claim 1.
- the invention also proposes a method for assembling a sanitary fitting with the features mentioned in claim 29. Further developments of the invention are the subject of the dependent claims, the wording of which, like the wording of the summary, is made the content of the description by reference.
- a separate cartridge housing is thus produced, in which the cartridge is inserted. It takes place So there is no longer an adaptation of the sanitary fitting to the cartridge, but rather an adaptation of an easy-to-manufacture cartridge housing to the cartridge or vice versa.
- a cartridge base is arranged in the cartridge housing between its base and the cartridge. This serves to realize the water flow between the inlets, the mixed water outlet and the cartridge.
- the cartridge base has connections for connecting lines, in particular for connecting hoses.
- the cartridge base can have, for example, nipples onto which the connecting hoses can be pushed.
- the sanitary fitting has a hose leading to the outlet from the sanitary fitting, which thus establishes the connection between the cartridge and the outlet snout. This also simplifies the construction of the sanitary fitting, since such a hose can be laid in almost any shape.
- the cartridge is clamped in the cartridge housing.
- the bracing can take place in particular against the bottom of the cartridge housing.
- Usual cartridges have the shape of a circular cylinder.
- the invention proposes bracing the cartridge with the aid of a ring element which engages on its end face facing away from the floor. On the one hand, this leads to a lower surface load and, on the other hand, leaves the center of the end face freely, through which the actuating element of the cartridge extends.
- the ring element engages on the edge of the cartridge housing.
- the ring element can be part of a bayonet lock that is simple to implement and easy to use.
- the ring element is designed as a nut element, that is to say cooperates with a thread.
- the ring element is screwed into a thread in the region of the open side of the cartridge housing.
- the invention proposes in a further development that this is achieved by deforming the cartridge housing in the region of its open side.
- the production by deformation has the advantage over the possible production of the thread by thread cutting that the production can be carried out in one work step with the production of the cartridge housing.
- the deformation can take place, for example, by embossing, deep-drawing or else by internal high-pressure molding.
- the thread is produced in such a way that the wall thickness of the cartridge housing remains constant.
- the thread is a round thread in which the threads are rounded.
- the cartridge housing with the cartridge used and possibly the connecting lines can be designed as a structural unit.
- the structural unit can be stored, packaged and transported. It can then be inserted into the fitting housing at the assembly point through an opening provided in it and then connected to the fitting housing.
- an outlet element for example with a ventilation device, can be connected from the outside of the fitting housing to the connecting hose connected to the mixed water outlet from the cartridge.
- the invention proposes as one of several possibilities to attach the cartridge housing to or in the sanitary fitting by attaching it to the edge of the opening, in particular by bracing.
- the cartridge housing has flexible latching projections which are arranged such that they spring back radially inwards through the opening when the cartridge housing is inserted and then move outwards again. The bracing then leads to the cartridge housing following is pulled on the outside until the locking projections lie on the inside around the edge of the opening.
- the bracing is advantageously carried out against the edge of the opening through which the cartridge housing is inserted.
- a bayonet lock can also serve as the clamping means.
- a nut as a clamping means which interacts with a thread of the cartridge housing in the region of its open side.
- the thread of the cartridge housing with which the clamping means cooperates can be realized by deforming the cartridge housing.
- the thread for the clamping nut of the cartridge housing also forms the thread for the clamping nut of the cartridge at the same time.
- the wall thickness remains constant in the section of the wall of the cartridge housing where these threads are to be present. This realizes both an internal thread and an external thread in the corresponding wall section of the cartridge housing.
- the clamping nut for the cartridge housing has or forms a cover which leaves a passage free for the actuating element of the cartridge. As a result, the entire arrangement for fastening the cartridge housing and the cartridge can be covered to such an extent that it is no longer visible to a user.
- the cartridge housing can advantageously be a simple sheet metal part, in particular a deep-drawn sheet metal part or a sheet metal part deformed by internal pressure.
- the thread can then be rolled up. With internal high pressure forming, the thread can be formed in one step.
- the shape of the cartridge housing corresponds approximately to the shape of a pot, i.e. a circular cylinder closed off by a floor on the opposite side.
- the cartridge housing from plastic, for example by an injection molding process.
- the cartridge possibly with the cartridge base, essentially completely fills the cartridge housing.
- the invention also proposes a cartridge housing for insertion in a sanitary fitting, as has been described here.
- the sanitary fitting proposed by the invention is assembled as follows. First, a commercially available mixer cartridge together with the hoses is inserted into the cartridge. inserted and fastened in this. This assembly is then inserted through an opening in the sanitary fitting and attached to the edge of the opening. The attachment takes place in such a way that the cartridge housing is arranged essentially completely in the fitting, and only the parts required for its attachment and operation are still outside the sanitary fitting. After insertion and fastening, the line connections can then be made with the house installation.
- FIG. 1 shows a section through a sanitary fitting proposed by the invention according to a first embodiment
- Fig. 3 is a section corresponding to Fig. 1 in a second embodiment of the invention.
- a sanitary fitting with a housing 1 is shown in section in FIG.
- the housing 1 is made of sheet metal.
- the housing 1 has a bottom 2 with an opening 3.
- a metal plate 4, for example, is arranged in the housing 1 and rests on the edge of the opening 3.
- a screw bolt 5 extends through an opening of the plate 4 and can be used, for example, to screw the sanitary fitting onto the top of a washbasin. The screwing happens by a nut that is screwed onto the screw bolt 5 from the underside of the washbasin.
- the plate 4 contains a central opening 6 through which connecting lines can be inserted.
- the housing 1 has approximately the shape of a cylinder, on one side of which an outlet spout 7 is formed, on the front of which an outlet element 8 is attached.
- the outlet element 8 can, for example, have a ventilation device in order to produce a ventilated jet.
- a handle 9 is arranged, which has a cover cap 10 and a bow handle 11 protruding from the cover cap 10. With the help of the handle 9, the mixing valve contained in the valve body 1 can be operated.
- the valve housing 1 contains, on its side facing away from the base 2, an opening into which a cartridge housing 12 is inserted.
- the cartridge housing is pot-shaped and has a bottom 12 provided with openings.
- the cartridge housing 12 contains an outwardly directed flange 14, see FIG. 2, with which it rests on the outside of the housing 1.
- individual projections 15 are arranged on the outside of the cartridge housing 12, which can be latching projections, which thus spring back into the opening when the cartridge housing 12 is inserted.
- a mixer cartridge 16 is accommodated in the cartridge housing 12 and has a diameter which corresponds approximately to the inner diameter of the cartridge housing 12. Between see the bottom 13 of the cartridge housing 12 and the mixer cartridge 16, a cartridge base 17 is arranged, which has connection nipples for connection hoses 18, 19. These are passed through the opening already mentioned in the bottom 13 of the cartridge housing 12. Two of the connecting hoses 18 lead through the opening 6 of the plate 4 and the opening 3 of the bottom 2 of the fitting housing 1. They serve to establish the connection with a cold water pipe and a hot water pipe of the house installation.
- the third connecting hose 19 leads to the outlet device 8 in the outlet spout 7.
- the cartridge housing 12 has in its end region opposite its base 13 a section 20 which can be seen on an enlarged scale in FIG.
- this section 20 the originally cylindrical wall of the cartridge housing is deformed to form a thread.
- the deformation is carried out in such a way that the wall thickness in this area 20 remains constant.
- a thread is formed both on the inside of the wall section 20 and on its outside, in the example shown with rounded threads.
- a clamping nut 21 is screwed into the inside of the thread formed thereby and presses with its flat underside 22 facing the mixer cartridge 16 onto the end face of the mixer cartridge 16.
- the mixer cartridge 16 is clamped against its cartridge base 17 and against the base 13 of the cartridge housing 12.
- the clamping nut 21 has a central passage 23 through which an extension 24 of the mixer cartridge 16, which can be seen in FIG. 1, extends.
- the clamping nut 21 has a plurality of holes 25, which are distributed over the circumference and extend in the axial direction and are used for attaching a clamping tool.
- a cover cap 26 is screwed onto the outside of the wall section 20 with the thread formed there and has an internal thread 27 on its inside.
- the cover cap 26 can be made of plastic, for example.
- the internal thread 27 is formed on the inside of the approximately cylindrical shell of the cover cap 26, while the approximately flat end face 28 of the cover cap 26 has an opening 29.
- An actuating element 30 of the mixer cartridge 16 extends through the opening 29, see FIG. 1 above, to which the handle 9 can be screwed.
- valve housing 31 is shown in section, which consists of cast iron.
- the valve housing 31 has a slightly different shape.
- the valve housing 31 is of simple construction and essentially consists of only one shell without internals.
- An outlet device 8 is arranged on its front, an opening on its upper side as in the embodiment according to FIG. 1, while a stud bolt 32 is screwed directly into the bottom 33 of the valve housing 31.
- a pull rod 34 for a drain valve leads through the wall of the valve housing 31.
- the sanitary fittings shown in the figures are assembled as follows.
- a cartridge housing 12 is produced as a simple sheet metal part, for example by deep drawing or by internal high pressure forming, the thread in the wall section 22 being produced at the same time.
- the cartridge base 17 with the three tubes attached to it is inserted into the cartridge housing, with the tubes first, which are inserted through the opening in the base 13 of the cartridge housing 12.
- the clamping nut 28 is then placed on and screwed into the wall section 20 until the cartridge is firmly seated in the cartridge housing 12.
- the cartridge housing 12 is approached with the free ends of the connecting hoses 18, 19 of the fitting and the free ends of the hoses are threaded through the opening in the top of the fitting housing 1, 31.
- Outlet device 19 certain hose is brought into the outlet spout 7, for example, by tilting the fitting and gripped through the opening for the outlet device 8. There the hose 19 is pushed onto the outlet device 8 and the outlet device 8 is connected to the opening. The cartridge housing 12 is then completely inserted into the valve housing 1, 31, the tubes 18 extending through the openings 3 and 35 and the tube 19 being deformed into the shape shown.
- the cover cap 26 is screwed onto the wall section 20 and the cartridge housing 12 is thereby clamped.
- the handle 9 can then be put on and connected to the extension 30.
- the fitting can be screwed onto the wash basin using bolts 5 or 32. It is of course also possible to first attach the fitting to the sink without the cartridge housing and only then insert the cartridge housing into the valve body.
