[0001] Shower head for a sanitary fitting

[0002] The present invention relates to a shower head for a sanitary fitting. Sanitary fittings are used, for example, to provide water as needed in a shower or bathtub.

[0003] A showerhead for a sanitary fitting can be designed, for example, as an overhead shower or a handheld showerhead and / or serve to distribute the water delivered by the sanitary fitting over a wide area. The showerhead can have at least one jet generator that can deliver the water in at least one jet type, for example, in the form of rain jets, full jets, massage jets, or pearl jets.

[0004] When showering or bathing, (liquid) soap, for example, in the form of shampoo or shower gel, is regularly used. Handling soap bottles while showering or bathing is cumbersome. For example, shelves or racks are required to place the soap bottles. The desired amount of soap must be manually measured and spread over the body. When dispensing the soap, a lot of it can be rinsed off unused. This leads to high soap consumption and increased environmental pollution.

[0005] The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide a shower head which facilitates the handling of the soap.

[0006] This object is achieved with a showerhead according to the features of the independent patent claim. Further advantageous embodiments of the invention are specified in the dependent patent claims. It should be noted that the features listed individually in the dependent patent claims can be combined with one another in any technologically expedient manner and define further embodiments of the invention. Furthermore, the features listed in the patent claims are further specified and explained in the description, with further preferred embodiments of the invention being presented.

[0007] A shower head for a sanitary fitting contributes to this, which has at least the following:

[0008] - a housing with at least one inlet channel for water;

[0009] - a soap reservoir for soap; and

[0010] - a movable separating element which can be adjusted at least partially into the soap reservoir by the water so that the soap can be pressed out of the soap reservoir.

[0011] The sanitary fitting is used in particular for the demand-based provision of water, in particular mixed water, in a shower or bathtub. Cold water at a cold water temperature and hot water at a hot water temperature can be supplied to the sanitary fitting, which can be mixed by the sanitary fitting, for example by means of a mixing valve or a thermostatic mixing cartridge, to form the mixed water at a desired mixed water temperature. The cold water temperature is in particular a maximum of 25 °C (Celsius), preferably 1 °C to 25 °C, particularly preferably 5 °C to 20 °C and / or the hot water temperature is in particular a maximum of 90 °C, preferably 25 °C to 90 °C, particularly preferably 55 °C to 65 °C. The mixed water can then be supplied to a shower, for example via a liquid supply line, for example in the form of a liquid hose.

[0012] The shower head can be an overhead shower or a hand shower, for example. The shower head can be permanently connected to a support, such as a wall or ceiling, or it can be movable by a user. By means of the shower head, the water or the mixed water can be released into the area surrounding the shower head, into the shower and / or into the bathtub. The shower head has a housing with at least one inlet channel for the water. The housing can be made at least partially of metal and / or plastic. The water can be supplied to the shower head via an inlet in the housing. The inlet can in particular be connectable to the liquid supply line. The inlet channel can extend through a handle of the housing. The water can in particular be supplied to at least one jet former and / or at least one nozzle of the shower head via the inlet channel.The at least one jet generator allows the water to be delivered in at least one jet type, for example, as rain jets, full jets, massage jets, etc. The shower head can have a plurality of nozzles, for example, on an underside of the housing and / or on a shower head of the shower head.

[0013] The shower head has a soap reservoir for (liquid) soap. The soap can be, for example, shower gel or shampoo. The soap reservoir is formed in particular in or on the housing. The soap reservoir can be a cavity that is, for example, at least partially formed and / or delimited by the housing. The soap reservoir can have a volume of, for example, 50 ml (milliliters) to 500 ml. The shower head, the housing, or the soap reservoir can have a refill opening for refilling the soap.

[0014] The shower head has a movable separating element. The separating element can be a movable piston or a movable wall, for example. The separating element can be adjusted at least partially into the soap reservoir by the water flowing into the housing via the inlet channel or by the water pressure of the water flowing into the housing via the inlet channel. The movable separating element can have a diameter of, for example, 20 mm to 200 mm, in particular orthogonal to a direction of movement of the separating element. The movable separating element can press the soap out of the soap reservoir so that the soap can be dispensed through the shower head, for example at least partially as foam. By dispensing the soap or foam via the shower head, manual handling of the soap by the user is no longer necessary. In addition, no storage space for soap containers is required. Furthermore, the soap or foam can be dispensed in a precise amount. In addition, less or no soap is used.No soap is rinsed away unused, thus reducing soap consumption and environmental pollution.

[0015] The movable separating element can be a membrane. The membrane can be made at least partially of an elastic material, such as rubber or silicone. The membrane can be adjustable by the water or by the water pressure, in particular by elastic deformation in the soap reservoir.

[0016] The movable separating element can separate the soap reservoir from a water chamber. The water chamber is formed, in particular, on a side of the separating element opposite the soap reservoir. The water chamber can be connected to the at least one inlet channel and / or the at least one inlet channel can open into the water chamber. The water can flow from the inlet via the at least one inlet channel into the water chamber. The water can flow, in particular, from the water chamber to the at least one jet former and / or to the at least one nozzle of the showerhead.

[0017] The soap reservoir can be detachably attached to the housing. The soap reservoir can be part of a cartridge, in particular a replaceable one. In addition, the separating element and / or the water chamber can be part of the cartridge. The cartridge can be connected to the housing, for example, via a plug-in connection, a snap-in connection, or a screw connection. The soap reservoir or the cartridge can be connected to the housing and / or detached from the housing without tools. The cartridge and / or the housing can be at least partially transparent so that the fill level of the soap in the soap reservoir can be seen. The soap can be dispensed via at least one soap line. The at least one soap line can extend at least partially through the housing and / or be formed at least partially through the housing.In particular, the soap can be supplied to the at least one jet generator, the at least one nozzle, and / or at least one foam outlet of the shower head via the at least one soap line. The at least one soap line can be designed at least partially as a liquid channel and / or hose line. The soap reservoir can be connected to the at least one soap line via a soap outlet of the soap reservoir. A dispensed quantity of soap and / or a mixing ratio between the soap and water can be controlled and / or predetermined by the cross-sections and / or geometries of the soap lines.

[0018] The dispensing of soap can be controlled by a valve. In particular, the mixing ratio between the soap and the water can be controlled by the valve. The valve can be formed in and / or on the soap line. The valve can be a shut-off valve and / or a dosing valve. The valve can be used to adjust the dispensing quantity of soap (to the environment). When the valve is closed, in particular only water can be dispensed through the shower. The shower can have an actuating element for actuating the valve. The actuating element can be a push button, for example. The actuating element can be arranged on the outside of the shower or the housing. The actuating element can be actuated or grasped by the user of the shower. Alternatively or additionally, the valve can be controlled by a sensor. The valve can be controlled or closed by a timer.
