Description

[0001] PC 230777 C September 15, 2023 Valve cartridge The invention relates to a valve cartridge. Valve cartridges are known, for example in single-lever mixing valves or push-push valves with or without additional temperature and / or flow adjustment. Valve cartridges have a housing which holds the individual parts together even when removed. It has become common practice to insert the valve cartridges into corresponding cup-shaped receptacles, each of which has hose receptacles or hose connections to establish a fluidic connection. The invention is based on the object of simplifying the structural design of a valve cartridge. To achieve the stated object, the features of claim 1 are provided according to the invention. In particular, the valve cartridge is characterized in that at least one plug-in receptacle is formed in the connection-side housing part.This can, for example, make it possible to connect hoses to the valve cartridges. The invention makes a separate cartridge receptacle, to which hose connections are formed or hoses are attached, unnecessary. In an advantageous embodiment, it is provided that the plug-in receptacle is designed for a preferably axially aligned plug-in connection of a connecting hose. This can, for example, make it possible to plug a connecting hose into the plug-in receptacle. PC 230777 C 2 / 13 September 15, 2023 In an advantageous embodiment, it is provided that the housing parts are connected by means of a loss prevention device. This can, for example, make it possible for a housing part on the operating element side to be connected to the housing part on the connection side in a loss-proof manner. This can be achieved, for example, by means of a snap or latching connection.In one advantageous embodiment, it is provided that at least two plug-in receptacles are formed. This can make it possible, for example, for two connecting hoses to be attached to the valve cartridge. In particular, it can be provided that at least three plug-in receptacles are formed. This can make it possible, for example, for three connecting hoses to be attached to the valve cartridge. The plug-in receptacles are designed, in particular, for a hot water hose, a cold water hose, and a mixed water hose. The valve cartridge thus enables hot and cold water to be mixed and the mixed water to be drained away via the mixed water hose. In one advantageous embodiment, it is provided that at least one plug-in receptacle has a pull-out protection feature.This can, for example, ensure that the connecting hoses inserted in the plug-in receptacle cannot be pulled out or cannot come loose on their own. In an advantageous embodiment, it is provided that the at least one plug-in receptacle projects beyond a support surface of the connection-side housing part. This can, for example, ensure that the plug-in receptacle is formed outside the control element-side housing part PC 230777 C 3 / 13 September 15, 2023. In particular, it can be provided that the at least one plug-in receptacle protrudes from the support surface that forms a housing base. This can, for example, ensure that the connecting hoses can be easily inserted into the plug-in receptacles. In particular, it is provided that the at least one plug-in receptacle protrudes in a tubular manner from the support surface that forms a housing base.In this way, for example, it can be achieved that tubular connection hoses with a round cross-section can be fastened in the plug-in receptacle. In an advantageous embodiment, it is provided that the housing part on the operating element side forms at least one opening for an operating element. In this way, for example, the operation of the valve cartridge can be achieved. In an advantageous embodiment, it is provided that at least two disks that can move relative to one another are arranged inside for fluid control, in particular in contact with one another. In this way, for example, a mixing ratio of hot and cold water as well as a water pressure in the valve cartridge can be adjusted. In particular, it can be provided that the at least two disks that can move relative to one another are made of ceramic on the inside. This minimizes, for example, limescale deposits on the ceramic disks.In an advantageous embodiment, at least one connecting hose is secured in the plug-in receptacle by a spring clip. This can, for example, create a pull-out protection for the connecting hose. In particular, the cold water hose and / or hot water hose is secured in the plug-in receptacle by a spring clip. These PC 230777 C 4 / 13 September 15, 2023 Water hoses are generally subjected to high pressure of 2 to 8 bar. The securing by a spring clip, which engages in the grooves of the hose nipples, holds the hoses very securely in the plug-in receptacles. In an advantageous embodiment, at least one connecting hose is secured in the plug-in receptacle by claws.This can, for example, create a pull-out protection for the connecting hose by having claws in the plug-in receptacle designed so that they counteract any pulling force acting in the opposite direction to the plug-in direction and prevent the hose from being pulled out. In particular, it is provided that at least the mixed water hose is secured by claws in the plug-in receptacle. This can, for example, provide advantageous protection for the mixed water hose, which is generally subject to lower pressure than the cold and hot water hoses. In one advantageous embodiment, connecting hoses include hose nipples with grooves. Securing elements such as spring clips can engage in the grooves to prevent pull-out and thus secure the connecting hoses.In an advantageous embodiment, it is provided that at least one connecting hose is secured in the plug-in receptacle by claws and a spring clip. This can, for example, ensure that the connecting hose is particularly advantageously secured in the plug-in receptacle through the combination of both securing elements. In this case or in general, it can be provided that at least one connecting hose is rotatable relative to the plug-in receptacle. This way, for example, torsional stresses on the connecting hose can be reduced. The rotatability can be achieved, for example, by the claws sliding on the connecting hose and / or by the rotatability of a claw carrier, on which the claws are formed, in a hold-down device that holds the claw carrier back. The hold-down device can, for example, be designed such that the claw carrier presses the claws into the connecting hose when a pull-out load is applied.The hold-down device and the claw carrier can interact in a manner known per se such that the connecting hose can be pulled out of the claw carrier when the claw carrier is held counter to the withdrawal direction. The invention will now be described in more detail using an exemplary embodiment, but is not limited to the exemplary embodiment. Further exemplary embodiments arise from combining the features of individual or multiple claims with one another and / or with individual or multiple features of the exemplary embodiment. Fig. 1 shows a valve cartridge according to the invention in a three-dimensional oblique view with connecting hoses, Fig. 2 shows a view of the plug-in receptacles of the connection-side housing part from Fig. 1, Fig. 3 shows a view of an inner side of the connection-side housing part from Fig. 1, Fig. 4 shows a valve cartridge according to the invention in a three-dimensional oblique view with connecting hoses, PC 230777 C 6 / 13 15.September 2023 Fig. 5 shows a variant of the valve cartridge from Fig. 4 and Fig. 6 shows a further variant of the valve cartridge from Fig. 4. The valve cartridge 1 has a housing part 2 on the operating element side, which is captively connected to a housing part 3 on the connection side. At least one plug-in receptacle 4 for a connecting hose 5 is formed in the connection-side housing part 3. The plug-in receptacle 4 and the housing part 3 are thus integrally connected and formed as a common injection-molded part. The plug-in receptacle 4 is designed for a preferably axially aligned plug-in connection of a connecting hose 5. In the example, the connecting hoses 5 are plugged in, in other examples they are plugged on. The housing parts 2, 3 are connected by means of a loss prevention device 7 (e.g. snap connection).In the example, at least two, in particular at least three plug-in receptacles 4 are formed, in particular for a hot water hose 13, a cold water hose 14, and a mixed water hose 15. Each of the plug-in receptacles 4 has a pull-out protection device 6. The plug-in receptacles 4 are each designed to form a non-detachable plug-in connection, in particular via the pull-out protection device 6. The pull-out protection device can, for example, have a securing element that engages in a groove 16 of the hose nipple 17 or claws into the connecting hose 5. Each plug-in receptacle 4 protrudes from a support surface 8 of the connection-side housing part 3. The support surface 8 can be used to clamp the valve cartridge 1 into a holder (not shown, for example on a sanitary fitting). The valve cartridge 1 is clamped between the support surface 8 and a counter surface 19 (shoulder) on the housing part 2.Each plug-in receptacle 4 thus protrudes, preferably in a tubular manner, from the support surface 8, which forms a housing base. The housing part 2 on the operating element side forms at least one opening 9 for an operating element 10. In the interior 11 (within the cup-shaped housing part 2), at least two disks 12, preferably made of ceramic, are arranged (concealed by the housing part 2) for fluid control, in particular in contact with one another, and are movable relative to one another. These disks can bear directly or indirectly against sealing elements on the housing part 3, which are inserted into a groove 18. The embodiment of the valve cartridge 1 shown in Figure 4 shows the connection-side housing part 3 with connecting hoses 4 inserted into the plug-in receptacles 4. The connecting hoses 4 have hose nipples 17 with a groove 16 into which a spring clip 21 engages and secures the connecting hoses 4. The spring clip 21 serves as a securing element.The connection-side housing part 3 and the plug-in receptacles 4 have receptacles 20 for the spring clip 21 so that the latter can be inserted there to secure the connecting hoses 4. The receptacles 20 are formed in the plug-in receptacles 4 of the hot water hose 13 and the cold water hose 14. In the embodiment shown, the cold water hose 14 and PC 230777 C 8 / 13 September 15, 2023 hot water hose 13 are secured in the plug-in receptacle 4 by a spring clip 21. The spring clip 21 is guided outside around the plug-in receptacle 4 of the mixed water hose 15 and forms a bend 22. The bend 22 extends from the spring clip insertion direction over the center 23 of the plug-in receptacle 4 of the mixed water hose 15, so that the bend 22 engages behind the mixed water hose 15 and narrows behind the mixed water hose 15. This creates a constriction.The spring clip 21 secures the connecting hoses 5 through the receptacles 20 in the connection-side housing part 3. The plug-in receptacle 4 of the mixed water hose 15 in Figure 4 has an additional locking mechanism 24. The embodiments shown in Figures 5 and 6 do not require the locking mechanism 24. Figure 6 shows a further embodiment of the valve cartridge 1, in which the receptacles 20 also extend to the plug-in receptacle 4 of the mixed water hose 15. The spring clip 21 thus clamps around the mixed water hose 15 and thereby forms a holding force on the mixed water hose 15, which fixes the spring clip 21 in its insertion direction. In an embodiment not shown, at least one connecting hose 15, in particular the mixed water hose 15, is secured by claws in the plug-in receptacle 4.In a further embodiment not shown, at least one connecting hose is secured in the plug-in receptacle 4 by claws and the spring clip 21.
