Description

TECHNICAL FIELD

[0001] The invention relates to a sanitary equipment fitting, which can be used in particular in wash basins, shower devices and / or baths. Furthermore, the invention relates to a method for assembling a corresponding sanitary equipment fitting. BACKGROUND

[0002] Sanitary equipment fittings are used in particular to supply water and / or to mix cold water and hot water to mixed water having a desired mixed water temperature and to dose the mixed water that is mixed. In known sanitary equipment fittings, the water is guided by a valve or the mixed water is guided by a mixing valve via a liquid channel in the fitting housing to a flow outlet of an outflow of the fitting housing. Since the water comes into contact with the fitting housing here, the fitting housing must be made of a material that is suitable for drinking water, for example brass. In order to be able to use a material that is less expensive, for example zinc or a zinc alloy, for the fitting housing, the liquid channel within the fitting housing must be configured, for example in the form of a plastic water guide, such that the mixed water does not come into contact with the fitting housing. Here, a problem exists in particular in the dimensioning and the positioning of the connection between the water guide at the outflow and the valve housing of the valve or the valve adapter of the mixing valve of the sanitary equipment fitting, since this connection either requires an increase in the diameter of the fitting housing or requires the fitting housing to be designed as a multipart fitting housing. SUMMARY

[0003] It is therefore an object of the present invention to at least partially solve the problems described with reference to the prior art and in particular to provide a sanitary equipment fitting in which the connection between the water guide at the outflow and the valve adapter of the valve is configured such that a one-piece fitting housing can be used without an increase in the housing diameter. Furthermore, a method for assembling a sanitary equipment fitting should also be given in which the connection between the water guide at the outflow and the valve adapter of the valve is configured such that a one-piece fitting housing can be used without an increase in the housing diameter.

[0004] The object is achieved with a sanitary equipment fitting and a method according to the features of the independent claims. Further advantageous design options of the invention are given in the dependent claims. It is pointed out that the features individually listed in the dependent claims can be combined with one another in any technically reasonable manner and define further design options of the invention. Furthermore, the features given in the claims are set out and explained in detail in the description, wherein further preferred design options of the invention are formed.

[0005] To this end, a sanitary equipment fitting is proposed, which comprises at least the following components:

[0006] - a fitting housing having an outflow with a flow outlet;

[0007] - a valve adapter arranged in the fitting housing;

[0008] - a valve for at least partially closing the outflow opening, which valve is at least partially arranged in the valve adapter;

[0009] - a connecting element for connecting the water guiding device arranged in the outflow portion to the water opening of the valve adapter, wherein the connecting element is fixed to the valve adapter by means of a linear sliding guide.

[0010] The proposed sanitary equipment fitting is in particular for providing water, for mixing cold water and hot water to mixed water having a desired mixed water temperature and / or for dosing the mixed mixed water. Such sanitary equipment fittings are typically used for wash basins, sinks, shower devices and / or baths. The sanitary equipment fitting has a fitting housing having an outflow portion with an outflow opening, wherein the fitting housing can be at least partially made of brass, zinc alloy and / or plastic. The fitting housing is in particular configured in one piece, that is to say in particular not composed of two (half) shells. Furthermore, the fitting housing can be fixed on a support, for example on a worktop, a wash basin, a sink, a shower device or a bath. Furthermore, the fitting housing has a (projecting or branched) outflow portion, which is rigidly or movably connected to the fitting housing. The outflow portion can be at least partially configured tubular. Furthermore, the fitting housing can have a decorative outer surface. Furthermore, the outflow portion has an outflow opening via which liquid, in particular (mixed) water, can be discharged.

[0011] In the fitting housing, a valve adapter for receiving and / or fixing a valve on the fitting housing is arranged. The valve adapter is in particular configured in the type of a cylindrical adapter. Furthermore, the valve adapter can be at least partially configured tubular, so that the valve can be at least partially arranged in the valve adapter. The tubular region of the valve adapter extends in particular along a longitudinal axis. Furthermore, the valve adapter can be at least partially made of brass and / or plastic. The valve adapter can be fixed on the fitting housing directly or indirectly, for example via other components of the sanitary equipment fitting.

[0012] By means of the valve, the outflow opening can be at least partially closed. This means in particular that by means of the valve, the outflow of water from the outflow opening can be prevented or can be inhibited. Furthermore, the valve can be configured in the type of a mixing valve or a mixing cartridge. With the mixing valve or the mixing cartridge, cold water having a cold water temperature and hot water having a hot water temperature can be mixed in particular into mixed water having a desired mixed water temperature. The cold water temperature is in particular at most 25°C (degrees Celsius), preferably 1°C to 25°C, particularly preferably 5°C to 20°C, and / or the hot water temperature is in particular at most 90°C, preferably 25°C to 90°C, particularly preferably 55°C to 65°C. The valve is at least partially arranged or fixed in the valve adapter and / or in the receiving cavity of the valve adapter. Furthermore, the valve can be actuated by means of a handle of the sanitary device fitting. The mixed water temperature and / or the discharge quantity of the mixed water or of the water can be adjusted for example by means of the handle. The mixing valve or the mixing cartridge can be configured for example in the type of a single lever mixer and / or at least partially cylindrically. Furthermore, the valve can have a cartridge housing.

[0013] Furthermore, the sanitary device fitting comprises a connecting element for connecting the water guiding device arranged in the outflow portion to the water opening of the valve adapter. The water guiding device can be a mixed water guiding device. The water flowing through the valve or the mixed water mixed by the valve flows in particular from the water outlet of the valve into the receiving cavity of the valve adapter and from there through the water opening of the valve adapter into the water guiding device of the outflow portion via the connecting element. For this purpose, a water channel can be formed in the connecting element. The water guiding device can be configured for example as a tube or a (flexible) hose and / or extends through the outflow portion to the outflow opening. The connecting element can be made at least partially from brass or plastic.

[0014] Furthermore, the connecting element is fixed on the valve adapter by means of a linear sliding guide. By means of the linear sliding guide, the connecting element can be moved or displaced (only) linearly, in particular in the longitudinal direction, that is to say in particular parallel to the longitudinal axis of the valve adapter. Furthermore, the connecting element can be detached from the valve adapter by means of the linear sliding guide, in particular only by a movement in the longitudinal direction. The linear sliding guide can be formed by a strip of the valve adapter, which engages into a bearing groove of the connecting element and which can be moved (only) linearly, that is to say in one (only) direction (forward and backward), in the bearing groove. Here, the strip and the bearing groove are configured in particular such that the valve adapter and the connecting element are positively connected to one another in particular in the radial direction of the valve adapter, that is to say in particular orthogonally to the longitudinal direction. For this purpose, the strip and / or the bearing groove can have at least partially a trapezoidal cross section.

[0015] The linear sliding guide device enables, firstly, the connecting element (in the absence of a valve adapter) to be arranged at least partially in the outflow portion and only subsequently the valve adapter to be inserted into the fitting housing. When the valve adapter is inserted into the fitting housing, the web can be guided into the bearing groove of the connecting element, so that the connecting element is fixed on the valve adapter and secured in its position in the outflow portion. In the region of the water opening of the valve adapter, a seal, for example of the O-ring type, can be arranged, which is pressed between the valve adapter and the connecting element when the web is guided into the bearing groove. The counterforce generated by the compression of the seal is not transmitted from the entire diameter of the valve adapter, but only in the region of the linear sliding guide device, whereby deformation of the valve adapter can be avoided. By fixing the connecting element on the valve adapter by means of the linear sliding guide device, an increase in the housing diameter of the fitting housing and / or a multi-part embodiment of the fitting housing can be avoided.

[0016] The connecting element can be fixed on the peripheral surface of the valve adapter by means of the linear sliding guide device.

[0017] The linear sliding guide device can be configured as a dovetail guide device.

[0018] The connecting element can have a dovetail groove. In this case, the bearing groove is configured as a dovetail groove having an at least partially dovetail-shaped cross section. Furthermore, the web of the valve adapter can also have an at least partially dovetail-shaped cross section. By means of the dovetail-shaped cross section of the web and the dovetail groove, the web can only move in one direction in the dovetail groove.

[0019] The connecting element can have a tube section. The tube section is in particular configured tubular and extends from a first longitudinal side end to a second longitudinal side end.

[0020] The connecting element can have a connecting section. The connecting section is in particular configured on the second longitudinal side end of the tube section and / or in the type of a flange. The bearing groove or the dovetail groove is in particular configured on the connecting section of the connecting element.

[0021] A seal can be arranged between the connecting element and the valve adapter. The seal is in particular configured in the type of an O-ring.

[0022] A water guide device can be inserted into the connecting element. In particular, the water guide device can be inserted into the connecting element or the first longitudinal side end of the tube section of the connecting element through the outflow opening.

[0023] The connecting element can be arranged at least partially in the outflow portion.

[0024] According to a further aspect, a method for assembling a sanitary device fitting is also provided, which method comprises at least the following steps:

[0025] a) providing a fitting housing having an outflow portion with a flow outlet;

[0026] b) arranging a connecting element at least partially in the outflow portion for connecting a water guiding device arranged in the outflow portion with a water opening of a valve adapter; and

[0027] c) arranging the valve adapter in the fitting housing, whereby the connecting element is fixed on the valve adapter by means of a linear sliding guide.

[0028] After providing the fitting housing in step a), the connecting element, in particular with its tube section, is arranged in the outflow portion and the support groove of the connecting element is oriented perpendicularly or in the longitudinal direction of the valve adapter in step b). Then, in step c), the valve adapter is inserted into the fitting housing, in particular via the cylinder opening of the fitting housing. Here, the slat of the valve adapter is introduced into the support groove of the connecting element, so that the slat and the support groove form a linear sliding guide. The connecting element is fixed on the valve adapter and secured in its position in the outflow portion by the linear sliding guide. With regard to further details, complete reference can be made to the description of the sanitary equipment fitting presented here. BRIEF DESCRIPTION OF DRAWINGS

[0029] The present invention and the technical field are explained in detail below with reference to the drawings. It is pointed out that the drawings show particularly preferred embodiments of the present invention, but the present invention is not limited thereto. Here, identical components are provided with identical reference signs in the drawings. The drawings show schematically:

[0032] Figure 3 : perspective view of a valve adapter of a sanitary equipment fitting. DETAILED DESCRIPTION

[0033] Figure 1A sanitary fitting 1 is shown in an exploded view. The sanitary fitting 1 includes a fitting housing 2 having an outflow portion 4 with an outflow opening 3. A valve adapter 5 is arranged in the fitting housing 2. The valve adapter has a receiving chamber 17 for accommodating a valve 6 and is designed in the manner of a cartridge adapter. The valve 6 is designed in the manner of a mixing cartridge. The receiving chamber 17 extends in a longitudinal direction 25, i.e., parallel to the longitudinal axis 26 of the valve adapter 5, from an upper end face 24 of the valve adapter 5 to a bottom portion of the receiving chamber 17 within the valve adapter 5 (not visible here). The valve adapter 5 is tubular in the region of the receiving chamber 17. The valve 6 has a lower end face 16, which fits onto the bottom portion of the receiving chamber 17 of the valve adapter 5. Cold water and hot water channels (also not visible here) are designed in the valve adapter 5 and extend from the underside 20 of the valve adapter 5 to the bottom portion of the receiving chamber 17. The cold water line 18 can be connected to the cold water channel on the underside 20 of the valve adapter 5, while the hot water line 19 can be connected to the hot water channel on the underside 20 of the valve adapter 5. Furthermore, the cold water line 18 and the hot water line 19 are secured by a clamp 21 that can be inserted into the valve adapter 5, preventing the cold water line 18 from becoming loose from the cold water channel and the hot water line 19 from becoming loose from the hot water channel of the valve adapter 5. The cold water channel and the hot water channel of the valve adapter 5 open into the cold water inlet and the hot water inlet of the valve 6 at the bottom of the receiving chamber 17. The cold water inlet and the hot water inlet are formed on the lower end face 16 of the valve 6. Within the valve 6, the cold water and the hot water can be mixed to form mixed water of a desired mixed water temperature. To adjust the mixed water temperature and the amount of mixed water discharged through the sanitary fitting 1, the valve 6 has an operating element 22 connected to a handle 23.

[0034] Mixed water mixed by valve 6 enters the receiving chamber 17 of valve adapter 5 at lower end face 16 from the mixed water outlet of valve 6 (not visible here). Receiving chamber 17 is closed by valve 6 in the region of upper end face 24 of valve adapter 5, so that mixed water can only leave receiving chamber 17 through water opening 9. To this end, valve 6 has an outer diameter from its lower end face 16 to water opening 9 that is smaller than the inner diameter of receiving chamber 17, allowing mixed water to flow in longitudinal direction 25 through the annular gap formed by valve 6 and valve adapter 5 to water opening 9. Water opening 9 is formed in the region of valve 6 along longitudinal direction 25 and extends through a side wall 28 of valve adapter 5 in radial direction 27, i.e., perpendicular to longitudinal direction 25. From water opening 9, mixed water can be conveyed via connecting element 7 and water guide 8 to outflow 3 of outflow 4. A bubbler 29 is arranged in outflow 3, through which the mixed water leaves outflow 4.

[0035] Figure 2 The connecting element 7 is shown in a perspective view. The connecting element 7 has a tube section 13 which extends from a first longitudinal end 30 to a second longitudinal end 31. Figure 1The water guiding device 8 shown in Fig. 1 can be inserted into the first longitudinal side end 30. On the second longitudinal side end 31 of the tube section 13, a connection section 14 of the connection element 7 is connected, which is configured here in the type of a flange. The connection section 14 comprises a dovetail groove 12, which has a first side 33 and a second side 34, which are configured mirror-symmetrically to one another and run parallel to one another. Furthermore, the dovetail groove 12 has a first width 32, which increases at least locally in the direction of the first longitudinal side end 30. The dovetail groove 12 thus has a (substantially) trapezoidal or dovetail-shaped cross section.

[0036] Figure 3 The valve adapter 5 is shown in a perspective view. On the outer peripheral surface 11 of the valve adapter 5, in the region of the water opening 9, a strip 35 is configured. The strip 35 protrudes from the outer peripheral surface 11 in the radial direction 27. Furthermore, the strip 35 has a first side edge 36 and a second side edge 37, which extend in the longitudinal direction 25 or parallel to the longitudinal axis 26 and are configured mirror-symmetrically to one another. Between the first side edge 36 and the second side edge 37, the strip 35 has a second width 38, which increases outwards in the radial direction 27. The strip 35 thus likewise has a (substantially) trapezoidal or dovetail-shaped cross section. The strip 35 is configured such that it can be slid in the dovetail groove 12 of the connection element 7 in the longitudinal direction 25 or parallel to the longitudinal axis 26. Furthermore, the strip 35 is configured such that it can be introduced into the dovetail groove 12 of the connection element 7 only (completely) in the longitudinal direction 25. The dovetail groove 12 of the connection element 7 and the strip 35 are part of a linear sliding guide 10, by means of which the connection element 7 can be fixed on the outer peripheral surface 11 of the valve adapter 5. If the strip 35 is located in the dovetail groove 12 of the connection element 7, the connection element 7 is connected form- fittingly to the valve adapter 5 in the radial direction 27 and can be released from the valve adapter 5 only in the longitudinal direction 25. In the strip 35, around the water opening 9, an annular groove 41 is configured for the sealing element 15 shown in Fig. 2, which is an O-ring. Figure 2 Figure 1

[0037] In the assembly of the sanitary fitting 1 shown in Fig. 1, in step a) the fitting housing 2 is first provided. Subsequently, in step b) the connection element 7 is introduced into the dovetail groove 12 of the valve adapter 5 in the longitudinal direction 25 or parallel to the longitudinal axis 26. In step c), the connection element 7 is then connected to the valve adapter 5 in the radial direction 27, in particular by means of a screw connection. In step d), the connection element 7 is then released from the valve adapter 5 in the longitudinal direction 25 or parallel to the longitudinal axis 26. Figure 1 Figure 2 ​​​The tube section 13 shown in the middle is inserted into the guide channel 39 of the outflow portion 4 such that the dovetail groove 12 of the connection element 7 is oriented in the longitudinal direction 25 or vertically. Thereafter, in step c), the valve adapter 5 is inserted into the fitting housing 2 through the barrel opening 40 of the fitting housing 2, thereby introducing the slat 35 of the valve adapter 5 into the dovetail groove 12 of the connection element 7. Thereby, the connection element 7 is fixed on the valve adapter 5 by means of the linear sliding guide 10 constituted by the dovetail groove 12 and the slat 35 and is secured in the guide channel 39 of the outflow portion 4. After step c), the seal 15 is pressed into the slot 41 between the valve adapter 5 and the connection element 7. Subsequently, the water guiding device 8 can be inserted in step d) via the outflow opening through the guide channel 39 into the tube section 13 of the connection element 7, such that the mixed water outlet of the valve 6 is connected in a liquid-conducting manner with the outflow opening 3 of the outflow portion, while the mixed water does not come into contact with the fitting housing 2 or the outflow portion 3.

[0038] By the invention, the water guiding device of the outflow portion can be connected with the water opening of the valve adapter without the housing diameter of the fitting housing increasing or without the fitting housing being designed as a multipart.
