Description

Technical Field

[0001] The present invention relates to a sanitary fitting, which has a fitting housing having an interior housing space, into which a cartridge or a cartridge adapter having a cartridge arranged in a cartridge receptacle of the cartridge adapter is inserted, the cartridge having at least one inlet opening connected to at least one outlet opening for guiding at least one fluid through the cartridge, and the sanitary fitting also having at least one hose line for conveying the at least one fluid to the cartridge, the hose line having a hose connecting element at least on its hose end facing the cartridge. Background Art

[0002] Sanitary water outlet fittings are used to provide the required fluid in the desired quality and quantity at the water intake point. Known sanitary fittings have a fitting housing for this purpose, which can be mounted, for example, on a wash basin used as a water intake point. The fitting housing has a housing interior space, into which a cartridge is inserted, by means of which the amount or the temperature of the water flowing out of the fitting outlet of the water outlet fitting can be adjusted. In the known cartridges, ceramic disks serve as shut-off elements. These ceramic disks rotate and move relative to one another and release the water flow steplessly. The position of the rod of the single-lever fitting, which corresponds to a specific relative position of the disks relative to one another, indicates the degree of opening of the cartridge.

[0003] Therefore, sanitary fittings of the type described at the beginning are known, which have a fitting housing constructed as a hollow body. The fitting housing has a housing interior space, into which a cartridge or a cartridge adapter is inserted, the cartridge adapter containing a cartridge arranged in a cartridge receptacle of the cartridge adapter. Since the cartridge with the valve disc is manufactured as a standardized component, the sanitary fitting can be adapted to a standardized cartridge by means of a cartridge adapter. In any case, the cartridge has at least one inlet opening, which is connected to at least one outlet opening so as to guide at least one fluid through the cartridge. At least one hose line is guided into the housing interior space of the fitting housing, the hose line being used to convey the at least one fluid to the cartridge. The hose line has a hose connecting element at least on its hose end facing the cartridge. Through the hose line and its hose connecting element, at least one fluid, in particular cold water and / or warm water, can flow through the cartridge from at least one inlet opening of the cartridge to at least one outlet opening, in which the amount of the fluid or at least one characteristic, such as its temperature, can be adjusted.

[0004] Here, the at least one fluid is conveyed to the cartridge of a known sanitary fitting via the at least one hose line. The hose line is abutted against the cartridge adapter with a hose line fitting or a similar hose connection element of the hose line so that the fluid guided in the at least one hose line can enter the cartridge via the hose connection element and the cartridge adapter. For this purpose, at least one hose holder protrudes in the housing interior space of the fitting housing, which is integrally formed on the housing inner circumference of the fitting housing. The at least one hose holder is penetrated by at least one insertion opening, through which a hose line can be inserted respectively. A circumferential retaining groove is provided on the circumference of the hose connection element, into which a clamping ring, a retaining clamp or a similar axial fixing device can be inserted after the hose line is inserted into the insertion opening. The axial fixing device prevents the hose line and its hose connection element from being pulled out of the insertion opening. The hose connection element of the at least one hose line abuts against the cartridge adapter in the region of the channel inlet opening of the through-flow channel, which leads to the inlet opening of the cartridge. The production of the insertion opening in the fitting housing, the sealing between the hose connecting element and the cartridge adapter and between the cartridge adapter and the cartridge are all associated with considerable effort.

[0005] WO 2009 / 065435 A1 discloses a hose fixing element for sanitary or kitchen fittings, which has at least two insertion channels, each extending to at least one receiving position, at which a flange of a hose nipple can be axially fixed on a connecting hose, wherein the hose fixing element has an internal recess, which is formed by a conveying region and the insertion channels, wherein the insertion channels are arranged at an angle to one another and open into the common conveying region.

[0006] EP 1 457 607 A2 discloses a device for fixing a pipeline, which device, for fixing the end of a pipeline on a sanitary fitting in the sanitary fitting, comprises a receptacle for a socket into which the socket can be pushed.

[0007] A hose connecting device is known from DE202017100423U1, which has a basic body on which at least two hose receptacles are formed, and the hose connecting device has at least two hoses, which are inserted into one of the at least two hose receptacles with their respective ends, wherein a retaining edge is formed in each of the at least two hoses, and the hose connecting device has a retaining plate in which at least two recesses are formed corresponding to the at least two hose receptacles, and one of the at least two hoses can be inserted into the recess respectively by an insertion movement oriented transversely to the longitudinal direction of the corresponding hose, so that the corresponding retaining edge bridges the retaining plate to prevent the hose from being pulled out of the hose receptacle.

[0008] EP 1 435 480 A2 discloses a sanitary fitting which contains in its mount an adapter component which contains a through-channel for conducting water in the sanitary fitting to a mixing valve.

[0009] A chromatography system and a connection part for the chromatography system are known from WO 2019 / 002515 A1.

[0010] EP 1 798 348 A2 discloses a hybrid battery having a battery body on which a water discharge pipe is arranged, wherein a receiving space for an insert having a mixing valve cartridge is provided in the battery body.

[0011] A form-fit connection of a connecting piece of a pipeline line is known from EP 1 496 164 A1. Summary of the invention

[0012] It is therefore an object of the present invention to provide a sanitary fitting of the type mentioned at the outset, the production of which is associated with significantly reduced effort.

[0013] The solution according to the invention to this task is particularly provided in sanitary fittings of the type described at the outset that the hose connection element of the at least one hose line is held on the cartridge or cartridge adapter in a holding position to prevent the hose line from being pulled out, and the hose connection element rests with its free front end defining the hose opening on the edge region of the cartridge defining the inlet opening provided. The sanitary fitting according to the invention has a fitting housing having a housing interior. The cartridge or cartridge adapter (in which the cartridge is arranged in a cartridge receptacle) is inserted into the housing interior. The cartridge receptacle of the cartridge adapter is intended for inserting a valve cartridge, a mixing cartridge or the like. The cartridge has at least one inlet opening, which is connected to at least one outlet opening in order to guide at least one fluid through the cartridge. The cartridge can be used to select the desired fluid, adjust the required amount and / or determine its temperature or similar fluid properties, for example by mixing cold water and warm water. Here, the at least one fluid can be delivered to the cartridge by means of a hose line, for example, warm water, cold water, boiling hot water or carbonated water, i.e. water containing CO2. In order to convey the fluid from the at least one hose line to the cartridge, the hose connection element of the at least one hose line is held on the cartridge or the cartridge adapter in a holding position to prevent the hose line from being pulled out. Here, the hose connection element, with its free front end defining the hose opening, rests against the edge region of the cartridge defining the inlet opening provided therewith in a liquid-tight manner. Since the hose connection element of the at least one hose line is held on the cartridge or the cartridge adapter in a holding position to prevent the hose line from being pulled out, the hose connection element cannot be pulled out of the cartridge or the cartridge adapter unintentionally. Therefore, in the sanitary fitting according to the invention, the hose line is held on the cartridge or the cartridge adapter with its hose connection element, rather than on the fitting housing. This has simplified the manufacture of the fitting housing. Since the free front end defining the hose opening of the at least one hose line with its hose connection element rests against the edge region defining the inlet opening of the cartridge in a liquid-tight manner, another annular seal between the hose line and the cartridge adapter can be omitted, which reduces manufacturing costs. If the sanitary fitting according to the invention requires a cartridge adapter, it is only penetrated by the hose line and no long and possibly intersecting flow channels are provided in the cartridge adapter. Since the at least one hose line rests against the cartridge in a liquid-tight manner, the cartridge adapter can be designed with a reduced installation length or the cartridge adapter can be completely omitted, which saves material for the cartridge adapter and the fitting housing that accommodates the cartridge adapter or the cartridge.

[0014] According to a particularly advantageous development of the invention, a through-opening is provided on the cartridge adapter or cartridge, into which an insertion groove opens, the insertion groove being designed to be open at the insertion opening transversely to the longitudinal axis of the cartridge adapter or cartridge, the at least one through-opening being provided with a hose connection element receptacle having a receiving shoulder or receiving bevel delimiting the through-opening, and a hose line assigned to the through-opening can be inserted into the through-opening through the insertion opening via the insertion groove in such a way that the hose connection element with its cross-sectional enlargement rests against the receiving shoulder or receiving bevel in a manner that prevents the hose line from being pulled out. In order to thereby secure the at least one hose line to the cartridge adapter or cartridge in a manner that prevents it from being accidentally pulled out from the through-opening provided in the cartridge adapter or cartridge, the hose connection element is inserted through the insertion opening into an insertion groove provided transversely to the longitudinal axis of the cartridge adapter or cartridge in order to be transferred from there into the through-opening. The receiving shoulder or receiving bevel is provided in the through-opening. Therefore, the at least one hose line assigned to the through-opening can be inserted into the through-opening through the insertion opening via the insertion groove in such a way that the hose connection element with the cross-sectional enlargement abuts against the receiving shoulder or receiving bevel so as to prevent the hose line from being pulled out. Therefore, the at least one hose line is inserted into the insertion groove from an insertion opening that is open transversely to the longitudinal axis of the cartridge adapter or cartridge, and the insertion groove opens into the through-opening on its side away from the insertion opening. A hose connection element receiving part in the cartridge adapter or cartridge is assigned to the through-opening, and the hose connection element receiving part has a receiving shoulder or receiving bevel that delimits the through-opening. Therefore, the hose line inserted into the insertion groove through the insertion opening can be inserted into the assigned through-opening from the insertion opening arranged inside or on the circumference of the cartridge adapter or cartridge in such a way that the hose connection element of the at least one hose line that passes through the through-opening abuts against the receiving shoulder or receiving bevel with the cross-sectional enlargement abuts against the receiving shoulder or receiving bevel so as to prevent the hose line from being accidentally pulled out from the cartridge or cartridge adapter.

[0015] In this embodiment according to the invention, which is designed in a relatively space-saving manner, the hose line is effectively prevented from being unintentionally pulled out in the direction away from the cartridge or the cartridge adapter.

[0016] Another suggestion for solving the above-mentioned object provides in a sanitary fitting of the type mentioned at the beginning that a hose connecting element of at least one hose line passes through a through-opening on a fitting housing in a retaining position, an insertion groove leads into the at least one through-opening, the insertion groove having an insertion opening at a groove end or a partial area of ​​the groove spaced apart from the through-opening, the insertion opening having an opening cross-section that is enlarged compared to the through-opening and / or being configured to be open on the edge side, the at least one through-opening being provided with a hose connecting element receiving portion, the hose connecting element receiving portion having a receiving shoulder or a receiving slope that defines the through-opening, and the hose line assigned to the through-opening is inserted into the through-opening through the insertion opening via the insertion groove so that the hose connecting element is held on the receiving shoulder or the receiving slope with a cross-sectional expansion portion to prevent the hose line from being pulled out, and the hose connecting element with its free front end that defines the hose opening abuts against an edge area of ​​a cartridge or a cartridge adapter that defines an assigned inlet opening. The sanitary fitting constructed according to this suggestion of the present invention also has a fitting housing, which has a housing interior space, into which a cartridge or a cartridge adapter having a cartridge in a cartridge receptacle is inserted in the insertion direction until the insertion stop. The cartridge adapter has a cartridge receptacle for inserting the cartridge. At least one fluid is guided through the cartridge, which flows through the cartridge from at least one inlet opening to at least one outlet opening. With the aid of the cartridge, the desired fluid can be selected, the required amount can be adjusted and / or its temperature or similar fluid properties can be determined, for example by mixing cold water and warm water. Here, the at least one fluid is respectively delivered to the cartridge by means of a hose line. In order to enable the fluid from the at least one hose line to flow into the cartridge, which may also be located in the cartridge adapter, the at least one hose line is abutted against the cartridge adapter or the cartridge with its hose connecting element. Here, the hose connecting element of the at least one hose line passes through a through-hole in a holding position, which is arranged on the fitting housing in the sanitary fitting according to this suggestion of the present invention. The insertion groove leads into the at least one through-opening, and the insertion groove has an insertion opening on the groove end or groove partial area spaced apart from the through-opening. The insertion opening may have an opening cross section enlarged compared to the through-opening and may be additionally or alternatively configured to be open on the edge side. In contrast, if the insertion opening is configured to be closed and only has an opening cross section enlarged compared to the through-opening, the insertion opening, the through-opening and the insertion groove connecting the two openings are configured to be keyhole-shaped. The at least one through-opening is provided with a hose connection element receiving portion, which has a receiving shoulder or receiving slope that defines the through-opening. Here, the hose line provided to the through-opening is inserted into the through-opening through the insertion opening via the insertion groove so that the hose connection element is fixedly abutted against the receiving shoulder or receiving slope with the cross-sectional expansion portion against the through-opening direction.

[0017] In order to form the at least one through-opening on the fitting housing, it is advantageous if at least one retaining flange projects into the housing interior on the housing inner circumference of the fitting housing and has the at least one through-opening and an insertion groove with an insertion opening associated therewith.

[0018] In this case, the cross-sectional expansion on the hose connecting element of the at least one hose line can be designed as an annular shoulder or an annular flange.

[0019] In order to prevent the hose connecting element held on the cartridge adapter or cartridge from accidentally moving in the area of ​​the through-opening and to hold the hose connecting element of the at least one hose line in a desired position on the cartridge adapter or cartridge, it is advantageous if an annular flange or a similar cross-sectional enlargement matches its outer contour to the clear cross-sectional shape of the hose connecting element receptacle.

[0020] Here, according to a preferred embodiment of the invention, it is provided that the hose connecting element is held on the cartridge, cartridge adapter or retaining flange in such a way that the end face of the annular flange facing away from the hose line is arranged approximately in or below the plane formed by the inner side of the cartridge, cartridge adapter or retaining flange.

[0021] In contrast, according to another advantageous embodiment of the invention, it is provided that the hose connection element is spherical or drop-shaped at its free end. If the free end of the hose connection element that rests against the associated inlet opening of the cartridge is spherical or drop-shaped, certain misalignments or manufacturing tolerances of the hose connection element can be compensated in this spherical joint-like region between the hose connection element on the one hand and the region of the cartridge that delimits the inlet opening on the other hand.

[0022] If the receiving bevel for receiving the spherical or drop-shaped hose connection element is designed in the shape of a spherical segment, this further facilitates the compensation of such misalignments or manufacturing tolerances. In this way, the receiving bevel of the hose connection element on the one hand and the hose connection element receptacle in the through-opening area on the other hand can interact in a spherical joint-like manner.

[0023] In order to be able to connect the hose opening delimited by the hose connecting element on the one hand and the associated inlet opening on the cartridge on the other hand and to avoid unintentional leaks in this area of ​​the sanitary fitting, it is advantageous if the hose connecting element and the adjacent inlet openings of the cartridge are sealed by an annular seal.

[0024] The position of the annular seal can be fixed in a simple manner if the annular seal is partially sunk into the associated hose connecting element receptacle in such a way that the annular seal is fixed in the hose connecting element receptacle.

[0025] If fluids with different fluid properties are to be drawn from the sanitary fitting according to the invention and if, in addition to warm and cold water, boiling hot water or carbonated water is to be selectively drawn from the sanitary fitting according to the invention, it is advantageous if at least two hose lines are held on the cartridge, the cartridge adapter or the fitting housing.

[0026] In order to design the liquid conduction between the hose connecting element on the one hand and the cartridge on the other hand to be liquid-tight toward the outside, and to avoid leakage flows in the connection area between adjacent inlet openings of the hose connecting element and the cartridge, it is advantageous if the adjacent inlet openings of the hose connecting element and the cartridge are radially and / or axially sealed by annular seals.

[0027] Axial sealing between the hose connection element and the adjacent cartridge can be achieved in a simple manner if a sealing ring designed as an annular seal is clamped between the free front end of the hose connection element, which defines the hose opening, and the edge region of the cartridge, which defines the associated inlet opening. In this embodiment, the free front end of the hose connection element rests with the aid of the sealing ring on the adjacent edge region of the cartridge, which defines the associated inlet opening.

[0028] In order to additionally or alternatively achieve radial sealing between adjacent edge areas of the hose connecting element and the core tube that define an associated inlet opening, it is provided in another advantageous embodiment of the invention that the core tube has a receiving cavity that is configured as a receiving portion for the hose connecting element, and an annular seal is arranged between the hose connecting element on the one hand and the circumferential wall of the core tube that defines the receiving cavity on the other hand.

DETAILED DESCRIPTION

[0042] Fig.10 and 11A sanitary fitting 201 according to a known prior art of the same type is shown. The sanitary fitting 201 known from the prior art has a fitting housing 202 designed as a hollow body, into whose housing interior 203 a cartridge adapter 204 is inserted in the insertion direction Pf1 up to an insertion stop 205. The cartridge adapter 204 has a cartridge receptacle 206 designed as a blind hole, which is intended for inserting a cartridge (not shown further here). At least one fluid, in particular cold water and / or warm water, can flow through the cartridge from at least one inlet opening of the cartridge to at least one outlet opening, wherein the amount or at least one property of the fluid, such as its temperature, can be adjusted in the cartridge.

[0043] In this case, the at least one fluid is conveyed to the cartridge of the known sanitary fitting 201 via at least one hose line 208. The hose line 208 rests on the cartridge adapter 204 with a hose connecting element 209 of the hose line 208 in such a way that the fluid conducted in the at least one hose line 208 can be conducted into the cartridge via the hose connecting element 209 and the cartridge adapter 204. For this purpose, at least one hose holder 210 projects into the housing interior 203 of the fitting housing 202 and is integrally formed on the housing inner circumference of the fitting housing 202. The at least one hose holder 210 is penetrated by at least one insertion opening 211, through which one hose line 208 can be inserted in each case. A circumferential retaining groove 212 is provided on the circumference of the hose connecting element 209, into which a retaining ring, a retaining clip 213 or a similar axial fixing device can be inserted after the hose line 208 has been inserted into the insertion opening 211. This axial securing device ensures that the hose line 208 and its hose connecting element 209 cannot be pulled out of the insertion opening 211. The hose connecting element 209 of the at least one hose line 208 rests on the cartridge adapter 204 in the region of the channel inlet opening 214 of the through-flow channel 215, which leads to the inlet opening of the cartridge. The insertion opening 211 is machined in the fitting housing 202, and the seals between the hose connecting element 209 and the cartridge adapter 204 and between the cartridge adapter 204 and the cartridge are associated with considerable effort.

[0044] exist Figures 1 to 5 , 6, 7 to 9 and 12 mainly show three different embodiments 100, 101 and 601 of the sanitary fittings according to the present invention and their respective components. The sanitary fittings 100, 101 and 601 have Figure 1 , 6 , 7 to 9 and 12, the accessory housing 102, 602 has a housing interior space 103, 603. Figure 6In the sanitary fitting 100 of FIG. 1 , the cartridge 106 is directly inserted into the housing interior space 103 along the insertion direction Pf1 until the insertion stop, while the cartridge adapter 104, 604 is inserted into the housing interior space 103, 603 of the sanitary fitting 101, 601, and the cartridge adapter has a cartridge accommodating portion 105 for inserting the cartridge 106. At least one fluid can flow through the cartridge 106 from at least one inlet opening of the cartridge 106 to at least one outlet opening, and the fluid can be, for example, warm water, cold water, boiling hot water and / or carbonated water. Here, for example, the at least one fluid in the cartridge can be adjusted in terms of the required amount and / or certain fluid properties. For this purpose, a valve disc 620, 621 or other regulating elements can be provided in the cartridge 106, which can be operated by means of an operating pin 107 that protrudes from the cartridge 106 and can be operated, for example, by a handle that is not further shown.

[0045] from Figure 1 , 6 , 7 to 9 and 12, it can be clearly seen that the at least one fluid is conveyed to the cartridge 106 via at least one flexible hose line 108, 608. The at least one hose line 108, 608 rests against the cartridge 106 or the cartridge adapter 104, 604 in a liquid-tight manner with a hose connecting element 109, 609 of the hose line 108, 608.

[0046] from Figure 1 , 6 As can be clearly seen from 12, the hose connecting element 109 of the at least one hose line 108 passes through the cartridge 106 in the holding position shown here (see Figure 6 ) or cartridge adapter 104 (see Figure 1 ) through-hole 110 on the . Here, the sanitary fittings 100, 101 are retained in the cartridge 106 (see Figure 6 ) or cartridge adapter 104 (see Figure 1 ) with its free front end defining the hose opening 111 rests in a liquid-tight manner (if necessary with the aid of or clamping annular seal 117) against an edge area of ​​the core 106 defining an inlet opening, so that the fluid guided in the hose line 108 can flow into the core via the hose opening 111 and the inlet opening of the core 106 without having to worry about leakage in the flow between the hose line 108 and the core 106.

[0047] In order to prevent the hose line 108 from being accidentally pulled out of the connection with the cartridge 106 or the cartridge adapter 104 , the hose connecting element 109 of the at least one hose line 108 is fixedly held on the cartridge 106 or the cartridge adapter 104 in a direction Pf2 away from the cartridge 106 by a through-opening 110 .

[0048] exist Figures 1 to 5 , 7 to 9 and 12 further shown in the sanitary fitting 101 cartridge adapter 104 is designed to be roughly pot-shaped and has, for example, three such through-openings 110 on its pot-shaped bottom. Similarly, Figure 6 The cartridge housing of the cartridge 106 shown in FIG. 1 is also designed in a pot-shaped manner and also has three such through-openings 110. Figures 1 to 5 , 6 and 7 to 9, it is clear that the insertion groove 112 opens into each through-opening 110, which is designed to be open to the insertion opening 113 arranged on the circumference of the cartridge adapter 104 or cartridge 106 on the outside. The cartridge housing of the cartridge adapter 104 or cartridge 106, which is designed to be pot-shaped, has, for example, three such through-openings 110 on its pot-shaped bottom. Each of these through-openings 110 is assigned a hose connection element receptacle 114, which has a receiving shoulder 115 that delimits the through-opening 110. Therefore, the hose line 108 assigned to one of the through-openings 110 can be inserted into the through-opening 110 through the insertion groove 112 through the insertion opening 113 so that the hose connection element 109 with the cross-sectional enlargement, which is designed here as an end face annular flange 116, rests fixedly on the receiving shoulder 115 against the through-opening direction Pf2. In order to also fix the hose connecting element 109 in its position transversely to the arrow direction Pf2 , the annular flange 116 is adapted in its outer contour to the clear cross-sectional shape of the hose connecting element receptacle 114 .

[0049] from Figures 1 to 6 It can be clearly seen that the hose connecting element 109 of the at least one hose line 108 is held on the cartridge 106 or Figures 1 to 5 7 to 9, so that the end face of the annular flange 116 facing away from the hose line 108 is arranged below the plane formed by the inner side of the cartridge housing or the cartridge adapter 104. In this way, the annular seal 117 can, for example, sink into the remaining recess of the hose connecting element receptacle 114 and prevent the annular seal 117 from sliding sideways. In order to enable the annular seal 117 to have a sufficiently large annular opening, it is advantageous if the hose connecting element receptacle 114 has a cross-sectional expansion that matches the outer contour shape of the annular seal 117 in the region of the recess that accommodates the annular seal 117. The annular seal 117 seals the hose opening 111 on the hose connecting element 109 on the one hand and the opposite inlet opening on the cartridge, which is therefore aligned in the flow direction, to the outside.

[0050] from Figure 1 and 12 It is clear from the comparison of the hose connection element 109 and the adjacent inlet openings of the cartridge 106 that the annular seal 117 can be radially and / or axially sealed. Figure 1It can be seen that the annular seal 117, which is designed as a sealing ring here, is clamped between the free front end of the hose connecting element 109 which delimits the hose opening 111 and the adjacent edge region of the cartridge which delimits the associated inlet opening and seals the liquid guide in this region axially to the outside. Fig.12 The core cartridge 106 in the embodiment has a receiving cavity configured as a hose connection element receiving portion, wherein an annular seal 117 is provided between the hose connection element 109 and the circumferential wall of the core cartridge 106 that defines the receiving cavity. Fig.12 In the embodiment shown, the liquid guide is sealed radially to the outside.

[0051] Figures 7 to 9 The sanitary fitting 601 shown in the figure has at least one through-hole 610 in the region of the housing interior space 603 of the longitudinal section of its fitting housing 602, and the at least one through-hole is arranged on the housing inner circumference of the fitting housing 602. The hose line 608 is held in the at least one through-hole 610 to prevent it from being pulled out of the through-hole 610 against the through-hole direction Pf2. An insertion groove 612 leads into the at least one through-hole 610, and the insertion groove has an insertion opening 613 at a groove end or a groove partial area spaced apart from the through-hole 610, and the insertion opening has an opening cross section enlarged compared to the through-hole 610 and / or is configured to be open on the edge side as here. For this purpose, at least one retaining flange 618 protrudes into the housing inner circumference of the fitting housing 602, and the retaining flange 618 has at least one through-hole 610 and an insertion groove 612 provided to the through-hole, including the insertion opening 613, which is open toward the edge of the retaining flange 618.

[0052] The at least one through-opening 610 is provided with a hose connection element receptacle 614, which has a receiving shoulder or receiving bevel 619 delimiting the through-opening 610. The hose line 608 assigned to the through-opening 610 can therefore be inserted into the through-opening 610 through the insertion opening 613 via the insertion groove 612 in such a way that the hose connection element 609 with the cross-sectional enlargement rests fixedly against the through-going direction Pf2 on the receiving shoulder or, as here, on the receiving bevel 619 of the hose connection element receptacle 614. The cross-sectional enlargement provided at the free end of the hose connection element 609 is spherical or drop-shaped in this case. By means of this drop-shaped design of the cross-sectional enlargement provided at the free end of the hose connection element 609 and the receiving bevel 619 loaded by the cross-sectional enlargement, misalignment and manufacturing tolerances of the hose connection element 609 can be compensated. This compensation of misalignments and manufacturing tolerances is further facilitated if the receiving bevel 619 has a spherical segment shape that matches the spherical or drop-shaped cross-sectional expansion provided on the hose connecting element 609. Figures 7 to 9In the sanitary fitting 601 shown, the hose connecting element 609 of the at least one hose line 608 and the adjacent inlet opening of the cartridge adapter 604 are also sealed by an annular seal 617, the hose connecting element 609 also resting with its free front end defining the hose opening 611 on the edge area of ​​the cartridge adapter 604 defining the assigned inlet opening.

[0053] Preferably, at least two hose lines 608 are also held on the fitting housing 602 of the sanitary fitting 601 , which are assigned to different fluids, such as cold water, warm water, boiling hot water or carbonated water.
