Description

The present invention relates to a shower for a sanitary fitting. Sanitary fittings are used, in particular, to supply liquids, such as water, to a sink, washbasin, shower or bathtub in line with requirements.

Showers for sanitary fittings can be designed, for example, in the manner of shower showers, overhead showers and / or hand showers and / or serve to distribute the liquid dispensed by the sanitary fitting over a large area. Furthermore, showers are known with which the liquid can be dispensed with different types of jets, for example in the form of rain jets, full jets, massage jets or pearl jets. The changeover between the individual jet types can be carried out using actuators on the showers, via which valves in the drainage channels can be controlled for the individual jet types. The disadvantage of this is that the actuating elements and the valves require a large installation space, so that the housing of the showers must be made correspondingly large. In addition, high forces are required to operate the valves, which reduce the comfort when operating the showers.

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, the valves of which are characterized by a small space requirement and which is easy to operate.

These tasks are solved with a shower according to the features of the independent claim. Further advantageous refinements of the invention are specified in the dependent patent claims. It should be pointed out that the features listed individually in the dependent claims can be combined with one another in any technologically meaningful manner and define further refinements of the invention. In addition, the features specified in the patent claims are specified and explained in more detail in the description, further preferred embodiments of the invention being illustrated.

• - ein Gehäuse mit zumindest einem Zuflusskanal und einer Mehrzahl von Ablaufkanälen,
• - eine Mehrzahl von Membranventilen, wobei die Membranventile jeweils eine an eine erste Seite einer Membran grenzende Eintrittskammer und eine an eine zweite Seite der Membran grenzende Gegendruckkammer aufweisen, wobei eine Flüssigkeit aus der Eintrittskammer über einen Druckausgleichskanal in die Gegendruckkammer eintreten kann, sodass ein Ablaufkanal der Mehrzahl von Ablaufkanälen infolge eines Flüssigkeitsdrucks der Flüssigkeit in der Gegendruckkammer durch die Membran verschließbar ist, und
• - ein Betätigungselement, das durch einen Benutzer in eine Mehrzahl von Ventilöffnungspositionen verstellbar ist, wobei das Betätigungselement in jeder Ventilöffnungsposition ein Membranventil der Mehrzahl von Membranventilen durch zumindest einen durch das Betätigungselement bewegten Magneten öffnet.

A shower, which has at least the following components, contributes to this:

• a housing with at least one inflow channel and a plurality of outlet channels,
• - A plurality of diaphragm valves, the diaphragm valves each having an inlet chamber bordering a first side of a membrane and a back pressure chamber bordering a second side of the membrane, a liquid from the inlet chamber being able to enter the back pressure chamber via a pressure compensation channel, so that a discharge channel A plurality of drainage channels can be closed by the membrane due to a liquid pressure of the liquid in the back pressure chamber, and
• an actuating element which can be adjusted by a user into a plurality of valve opening positions, the actuating element opening a diaphragm valve of the plurality of diaphragm valves in each valve opening position by at least one magnet moved by the actuating element.

Sanitary fittings serve in particular to supply liquids, such as water, to sinks, sinks, showers and / or bathtubs in line with requirements. For this purpose, a cold water with a cold water temperature and a hot water with a hot water temperature can be supplied to the sanitary fittings, which can be mixed by the sanitary fittings, for example by means of a mixing valve or a thermostatic mixing cartridge, to a mixed water with 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 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 fed, for example via a liquid line or a liquid hose, to a shower, which is designed, for example, in the manner of a shower shower, overhead shower or hand shower. The shower head can be firmly connected to a support, such as a wall, or can be moved by a user. The liquid can be sprayed by means of the spray in particular with a plurality of different types of jet.

For this purpose, the shower has a housing with at least one inflow channel and a plurality of outflow channels. The housing can at least partially consist of metal and / or plastic. The liquid can be fed to the shower via the at least one inflow channel. For this purpose, the inflow channel can in particular be connectable to the liquid line or the liquid hose of the sanitary fitting. By means of the plurality of drainage channels, the liquid can be able to be supplied to at least one jet generator, by means of which different jet types can be generated. Each outflow channel is in particular assigned to a different jet type, so that the spray type that is assigned to the respective outflow channel through which the liquid flows out is formed by the shower. The Housing has in particular three drainage channels for three different jet types.

Furthermore, the shower has a plurality of diaphragm valves, by means of which the plurality of drain channels can be closed. For this purpose, the plurality of diaphragm valves is arranged in particular in the plurality of drain channels. In particular, the shower has a membrane valve for each discharge channel. The diaphragm valves each have an inlet chamber bordering a first side of a membrane and a back pressure chamber bordering a second side of the membrane. The liquid flows through the at least one inflow channel into the inlet chamber, which can be annular in the area of the membrane. The liquid can enter the counter-pressure chamber from the inlet chamber via a pressure compensation channel. The pressure compensation channel can be, for example, an opening in the membrane or a channel in a valve housing of the membrane valve, which connects the inlet chamber to the counter-pressure chamber. In the operation of the shower there is therefore essentially the same liquid pressure in the inlet chamber and the back pressure chamber. The second side of the membrane borders on the back pressure chamber with a larger area than on the first side of the inlet chamber, so that the force resulting from the liquid pressure on the membrane in the back pressure chamber is greater than in the inlet chamber. The membrane is therefore pressed in the closed state of the membrane valve by the liquid pressure in the back pressure chamber against a valve seat, which is formed in particular by a longitudinal end of an outlet channel of the plurality of outlet channels. The drain channel is thus closed by the membrane, so that no liquid can flow out of the back pressure chamber via the drain channel.

In addition, the shower head has an actuating element which can be actuated by a user. This means in particular that the at least one actuating element is arranged in such a way that it is accessible to the user when using the sanitary fitting. The desired spray type of the shower can be set by means of the at least one actuating element. For this purpose, the actuating element can be adjusted by the user into a plurality of valve opening positions, the actuating element opening a (different) diaphragm valve of the plurality of diaphragm valves in each valve opening position. The membrane valves are opened by at least one magnet moved by the actuating element, which is in particular a permanent magnet. For this purpose, the at least one magnet can be attached to the actuating element, for example. The at least one magnet can be moved by the actuating element in such a way that the at least one magnet in the valve opening positions of the actuating element is so close to the membrane valve to be opened that a closing element of the membrane valve to be opened is in a magnetic field of the at least one magnet. The closing element of the diaphragm valve to be opened is adjusted by the magnetic field of the at least one magnet, so that (in the operation of the shower) a liquid pressure in the back pressure chamber drops until the force on the diaphragm resulting from the liquid pressure in the back pressure chamber is less than that force resulting from the fluid pressure in the inlet chamber. As a result, the membrane, which in particular at least partially consists of an elastic material, is lifted off the valve seat, so that the membrane valve is opened and the liquid can flow out of the counterpressure chamber through the outlet channel. For each jet type and / or per diaphragm valve, the actuating element has, in particular, a valve opening position. If the actuating element is located in one of the valve openings, the diaphragm valve assigned to the respective valve opening position is opened, the other diaphragm valves preferably being closed. Thanks to the diaphragm valves, the shower can be made particularly compact and can be operated particularly comfortably by the actuating element.

The membrane can have a pressure-reducing opening which connects the counter-pressure chamber to one of the outlet channels of the plurality of outlet channels and which is closed by a closing element when the membrane valve is closed. The pressure reduction opening is arranged in particular in the region of the valve seat, which is formed in particular by a longitudinal end of one of the drainage channels. The closing element is designed, for example, in the manner of a piston. Furthermore, the closing element is at least partially arranged in the back pressure chamber and / or covers the pressure reduction opening in the closed state of the diaphragm valve on the second side of the membrane in such a way that no liquid can flow out of the back pressure chamber through the pressure reduction opening into the outlet channel.

The closing element can be held on the pressure reduction opening with a spring. This can prevent the closing element from moving away from the pressure reduction opening in the closed state of the diaphragm valve, so that the diaphragm valve opens unintentionally. The spring is, in particular, a compression spring which presses the closing element onto the pressure reduction opening with a spring force.

The closing element can be adjusted by the at least one magnet when the actuating element is in the respective valve opening position, so that the pressure reduction opening is opened. The shooting element is adjusted by the magnetic field of the at least one magnet, in particular against the spring force of the spring. This means that the spring is tensioned when the fleece element is adjusted. The closing element can be guided, for example, by a guide during the adjustment.

The closing element can at least partially consist of a magnetizable material. The magnetizable material is particularly steel.

Furthermore, the closing element can at least partially consist of a valve magnet. This means in particular that the closing element itself is designed as a (valve) magnet. The closing element is in particular arranged such that the closing element and the at least one magnet of the actuating element attract each other in the respective valve opening position due to their magnetic fields. The valve magnet is also in particular a permanent magnet.

The actuating element can have at least one magnet per diaphragm valve. In this way, an adjustment path of the actuating element to be covered between the individual valve opening positions can be reduced.

The actuating element can be mounted in a tiltable manner. For this purpose, the shower may have a bearing for the actuating element, which supports the actuating element in particular in a central area. As a result, the actuating element can in particular be tilted into the various valve opening positions, as a result of which a distance between the at least one magnet and the closing element of the diaphragm valve to be opened is reduced until the magnetic field of the at least one magnet adjusts the closing element.

The actuating element can be rotatably mounted. For this purpose, the shower may have a bearing for the actuating element, which supports the actuating element in particular in a central area. The actuating element can hereby be rotated in particular into the different valve opening positions, whereby a distance between the at least one magnet and the closing element of the membrane valve to be opened is reduced until the magnetic field of the at least one magnet adjusts the closing element.

The actuator can be slidably mounted. For this purpose, the shower may have a bearing for the actuating element, which supports the actuating element (relative to the housing) in a displaceable manner. As a result, the actuating element can in particular be pushed into the different valve opening positions, as a result of which a distance between the at least one magnet and the closing element of the diaphragm valve to be opened is reduced until the magnetic field of the at least one magnet adjusts the closing element.

The invention and the technical environment are explained in more detail below with reference to the figures. It should be pointed out that the figures show particularly preferred embodiment variants of the invention, but this is not restricted to this. The same components are provided with the same reference numerals in the figures. Exemplarily and schematically, they show:

• 1 : a first embodiment of a shower in a plan view;
• 2 : a diaphragm valve in longitudinal section;
• 3 : the first variant of the shower in a side view;
• 4 : a second embodiment of a shower in a plan view;
• 5 : a third embodiment of the shower in a side view with an actuating element in a first valve opening position;
• 6 : the third embodiment of the shower in a side view with the actuating element in a second valve opening position; and
• 7 : the third embodiment of the shower in a side view with the actuating element in a third valve opening position.

The 1 shows schematically a first embodiment of a shower 1 in a top view. The shower 1 has a housing 2 with an inflow channel 3 drain channels not shown here 4 on. The inflow channel 3 can be connected to a liquid line or a liquid hose of a sanitary fitting, not shown here, via which the shower 1 a liquid can be supplied. The liquid is through the inflow channel 3 a first diaphragm valve 5.1 , a second diaphragm valve 5.2 and a third diaphragm valve 5.3 feedable. The diaphragm valves 5.1 . 5.2 . 5.3 are in the housing 2 arranged. On a top 22 of the housing 2 is an actuator 12 arranged that centered with a bearing 18th on the housing 2 is stored. Through the camp 18th is the actuator 12 around the camp 18th tiltable. On the actuator 12 are a first magnet 14.1 , a second magnet 14.2 and a third magnet 14.3 attached such that this is above the first diaphragm valve 5.1 , the second diaphragm valve 5.2 and the third diaphragm valve 5.3 are located. The magnets 14.1 . 14.2 . 14.3 are by tilting the actuator 12 around the camp 18th limited mobility.

The 2 shows an example of the first diaphragm valve 5.1 in longitudinal section, the second diaphragm valve 5.2 and the third diaphragm valve 5.3 are identical. The first diaphragm valve 5.1 has a valve housing 19 on, in which an elastic membrane 7 is attached. In a lower area of the valve housing 19 is an entry chamber 8th trained to a first side 6 the membrane 7 borders. The liquid can flow through the inflow channel 3 into the entry chamber 8th stream. The entrance chamber 8th is via a pressure equalization channel 11 in the membrane 7 with a back pressure chamber 10 in the upper area of the valve housing 19 connected, the back pressure chamber 10 to a second side 9 the membrane 7 borders. In the operation of the in the 1 shown shower 1 the liquid flows from the inlet chamber 8th through the pressure equalization channel 11 into the back pressure chamber 10 , so in the entry chamber 8th and the back pressure chamber 10 the fluid pressure is essentially the same. Because the back pressure chamber 10 with a larger area to the membrane 7 borders as the entry chamber 8th , results from the liquid pressure in the back pressure chamber 10 a greater force on the membrane 7 than in the entry chamber 8th , The membrane 7 is thereby against a valve seat 20th pressed by a longitudinal end 23 a drain channel 4 is formed. In the area of the valve seat 20th the membrane also has a pressure reduction opening 15 on that the back pressure chamber 10 with the drain channel 4 connects. The pressure relief opening 15 is with a closing element 16 sealed that with a spring 17 against the second side 9 the membrane 7 is pressed. This means that no liquid can escape from the back pressure chamber 10 via the drain channel 4 flow away. The first diaphragm valve 5.1 is closed. To open the first solenoid valve 5.1 is that in the 1 shown first magnet 14.1 with the actuator 12 (in the 1 ) down towards the first diaphragm valve 5.1 tiltable or movable so that the closing element 16 by a magnetic field of the first magnet 14.1 against a spring force of the spring 17 from the pressure relief opening 15 is lifted off. This allows the liquid from the back pressure chamber through the pressure equalization channel 11 drain off, so that the liquid pressure in the back pressure chamber 10 reduced until that from the fluid pressure in the back pressure chamber 10 resulting force on the membrane 7 is smaller than that from the liquid pressure in the inlet chamber 8th resulting force on the membrane 7 , Because the membrane 7 is elastic, this is due to the membrane seat 20th lifted off so that the drain channel 4 is fully open. The liquid is then through the drain channel 4 can be fed to a jet generator (not shown here) to form a jet type.

The 3 shows schematically the first variant of the shower 1 in a side view. The actuator 12 is in the operating situation of the shower shown here 1 around the camp 18th to a first valve opening position 13.1 tilted so that a distance 21 between the first magnet 14.1 is reduced to the extent that the magnetic field of the first magnet 14.1 that in the 2 shown closing element 16 to open the first diaphragm valve 5.1 adjusted. The rest in the case 2 arranged diaphragm valves 5.2 . 5.3 are in the first valve opening position 13.1 closed.

The 4 shows schematically a second embodiment of the shower 1 in a top view. The second variant of the shower 1 differs from the first version of the shower 1 only in that the actuator 12 just a first magnet 14.1 has and the actuator 12 around the camp 18th is rotatable. The actuator 12 is in the in the 4 shown operating situation of the shower 1 in a first valve opening position 13.1 in which the first magnet 14.1 above a first diaphragm valve 5.1 is arranged so that the magnet 14.1 the first diaphragm valve 5.1 opens. By turning the actuator 12 around the camp 18th can be the first magnet 14.1 to open a second diaphragm valve 5.2 via the second diaphragm valve 5.2 or to open a third diaphragm valve 5.3 via the third diaphragm valve 5.3 be moved. The diaphragm valves 5.1 . 5.2 . 5.3 are identical to that in the 2 shown first diaphragm valve 5.1 educated.

The 5 shows schematically a third embodiment of the shower 1 , which differ from the first variant and second variant of the shower 1 only by an actuator 12 distinguishes that slidably on the housing 2 is stored. The actuator 12 is in the in the 5 shown operating situation of the shower 1 in a first valve opening position 13.1 in the distance 21 between a first magnet 14.1 and a first diaphragm valve 5.1 is reduced to the extent that a magnetic field of the first magnet 14.1 the first diaphragm valve 5.1 opens. A distance between a second magnet 14.2 and a second diaphragm valve 5.2 and a distance between a third magnet 14.3 and a third diaphragm valve 5.3 is in the first valve opening position 13.1 of the actuator 12 so big that the second diaphragm valve 5.2 and the third diaphragm valve 5.3 are closed.

The 6 shows schematically the third variant of the shower 1 , with the actuator 12 in a second valve opening position 13.2 located. In the second valve opening position 13.2 became the distance 21 between the second magnet 14.2 and the second diaphragm valve 5.2 reduced so far that the second diaphragm valve 5.2 is open. The first diaphragm valve 5.1 and the third diaphragm valve 5.3 are in the second valve opening position 13.2 of the actuator 12 closed.

The 7 shows schematically the third variant of the shower 1 , with the actuator 12 in a third valve opening position 13.3 located. In the third valve opening position 13.3 became the distance 21 between the third magnet 14.3 and the third diaphragm valve 5.3 reduced so far that the third diaphragm valve 5.2 is open. The first diaphragm valve 5.1 and the second diaphragm valve 5.2 are in the third valve opening position 13.3 of the actuator 12 closed.

The invention enables a shower, by means of which several jet types can be generated, to be designed with a small space requirement, the shower being easy to operate.
