Definitions
- the present invention relates to a sanitary shower head for providing water with an outlet device.
- Sanitary showers can be fluidly connected to a sanitary fitting and are used, for example, to provide water as needed in sinks, washbasins, bidets, bathtubs and/or showers.
- the water flows from an outlet device which is designed to form a water jet.
- a typical problem with sanitary showerheads is that limescale deposits, especially with hard supply water, or other deposits accumulate in the outlet device over time. This can lead to reduced water flow and a deteriorated spray pattern. In addition, such deposits in the outlet device can ultimately lead to damage to the shower.
- sanitary shower heads known from the prior art are usually cleaned manually, for example mechanically by gently pressing and rubbing the outlet device and/or chemically by applying and acting on the outlet device with suitable cleaning agents, for example citric acid.
- suitable cleaning agents for example citric acid.
- manually cleaning the outlet device is relatively time-consuming.
- Another typical problem with sanitary showers is the water running after the water flow has been closed by the user by closing a corresponding valve.
- Water overflow means that after you have finished using the sanitary shower, a small amount of water still flows or drips out of the sanitary shower, even though the user has already closed the valve. Water may continue to run after a few seconds or minutes to a few hours after you stop using the device sanitary shower takes place. This is particularly undesirable when the water running from the sanitary shower hits already dried surfaces of the sink, washbasin, bidet, bathtub and/or shower. This can result in water stains or other marks on these surfaces. It is also undesirable for the water to continue running from the sanitary shower if the water drips onto the user after they have already dried themselves. In any case, running water from the sanitary shower means that the sink, washbasin, bidet, bathtub and/or shower must be at least partially dried again or that the user must at least partially dry themselves again. This is often perceived as disturbing.
- the present invention is therefore based on the object of at least partially solving the problem explained above and, in particular, of providing a sanitary shower head which facilitates its cleaning and which prevents or at least reduces the running of water.
- a sanitary shower for providing water with an outlet device comprising a jet shaping unit and a locking unit movable relative to the jet shaping unit, the locking unit being set up when the pressure or internal pressure in the outlet device resulting from inflowing water exceeds a definable pressure value or pressure or value, to open the jet shaping unit, and otherwise to lock the jet shaping unit.
- the locking unit serves to open and lock the jet shaping unit, that is to say to open and lock the water outlet, depending on the pressure prevailing in the outlet device incoming water creates internal pressure.
- the outlet device forms a space that can be filled with the inflowing water. When this space is completely filled with water and more water flows in, the pressure in the outlet device gradually increases.
- the jet shaping unit opens and water then flows out of the outlet device.
- the jet forming unit closes or blocks itself and no water flows out of the outlet device. In this way, water running after the water flow has been closed by the user by closing a corresponding valve is prevented.
- the sanitary shower according to the invention can be designed as a hand shower in order to enable a spatially targeted provision of the water, or can be designed as an overhead shower in order to enable the water to be provided in a particularly convenient manner for the user.
- the outlet device is a water outlet device and is used to drain water from the sanitary shower.
- the jet shaping unit is cleaned mechanically and without manual intervention. Any accumulated limescale or other deposits within the jet forming unit of the outlet device come into contact with the locking unit due to the relative movement and are thereby crushed and removed. The deposits removed in this way are carried away directly from the sanitary shower by the flowing water. This happens automatically in the sense of just the mechanism in the sanitary shower according to the invention that can be moved by water pressure. This eliminates the need for manual cleaning of the sanitary shower head to remove such deposits. This makes it easier to clean the sanitary shower head according to the invention, especially if the sanitary shower head is in places that are difficult to access is appropriate. Blocking the jet shaping unit when the internal pressure in the outlet device does not exceed the definable value, but rather is below the definable value, also prevents water from running over.
- the outlet device comprises a spring unit for resilient mounting of the locking unit.
- the spring unit comprises at least one spring, in particular a compression spring.
- the locking unit and the spring unit are firmly connected to each other.
- the spring unit biases the locking unit in the direction of the jet shaping unit by its spring force, that is, the locking unit presses in the direction of the jet shaping unit through this spring force.
- the internal pressure in the outlet device acts against the spring force of the spring unit.
- the definable value can be adjusted by the spring force of the spring unit.
- the spring force is particularly structurally adjustable.
- the definable value is smaller in particular if the spring unit comprises fewer springs and/or if the springs of the spring unit have a lower spring stiffness overall.
- the definable value is greater in particular if the spring unit comprises more springs and/or if the springs of the spring unit have a greater spring stiffness overall. This makes it possible to precisely set the definable value, when exceeded, the jet forming unit opens and water can flow out of the jet forming unit, thus indirectly facilitating the cleaning of the sanitary shower.
- the jet shaping unit is made of an elastic material, in particular an elastomer or rubber. This has a favorable effect on the functioning of the sanitary shower head according to the invention and thus further facilitates its cleaning.
- the locking unit is made of a non-elastic material, in particular of a hard plastic or of a metal or a metal alloy.
- the locking unit is in particular made of a material that is harder or stronger than the material from which the jet shaping unit is made.
- the jet shaping unit has at least one nozzle and the locking unit has at least one pin, with a pin and an associated nozzle being arranged in pairs coaxially or aligned with one another.
- the number of pins and the number of nozzles correspond, i.e. the shower has one nozzle per pin and vice versa.
- the number and arrangement of the nozzles determine the steel appearance.
- Each of the at least one pins can be displaceable in the direction of or along its own longitudinal axis.
- each of the at least one pins and each of the at least one associated nozzle are designed to complement each other in shape.
- a pin inserted into an associated nozzle closes this nozzle so that no water can flow out of this nozzle and out of the jet forming unit.
- the at least one pin can be displaceable into the associated nozzle and can be displaceable out of the associated nozzle.
- the locking unit is set up to open the jet shaping unit by pushing the at least one pin out of the at least one associated nozzle, that is to say by pushing out the at least one pin the at least one associated nozzle.
- This pushing out opens the flow channel of the at least one associated nozzle, so that the inflowing water can flow out of the jet forming unit of the outlet device through the flow channel that became free due to the pushing out.
- the locking unit is set up to lock the jet shaping unit by pushing the at least one pin into the at least one associated nozzle, that is to say by pushing the at least one pin into the at least one associated nozzle.
- the pin and nozzle being designed in particular with a shape that complements one another, the flow channel of the at least one associated nozzle closes, so that the inflowing water is prevented from flowing out of the jet shaping unit of the outlet device through the flow channel. Because the jet forming unit is blocked, water running over is prevented or at least reduced.
- Figure 1 shows an embodiment of the sanitary shower according to the invention in a sectional view.
- the sanitary shower according to the invention shown in the figure serves to provide water and comprises an outlet device 1, a water guide 2 in the form of a water channel and a water inlet 3, which can be connected to a sanitary fitting.
- the outlet device 1, the water guide 2 and the water inlet 3 are fluidly connected to one another, so that Water flowing into the shower through the water inlet 3 can flow via the water guide 2 into the outlet device 1 and finally out of it.
- the outlet device 1 comprises a jet shaping unit 4 and a locking unit 5 that is movable relative to the jet shaping unit 4.
- the outlet device 1 forms a space 6 which can be filled with the inflowing water.
- the locking unit 5 is set up to open the jet forming unit 4 when the pressure resulting from inflowing water in the outlet device 1, that is to say in the space 6, exceeds a definable value, and otherwise, that is when the pressure resulting from inflowing water in of the outlet device 1 does not exceed or is below the definable value to block the jet shaping unit 4.
- the relative movements between the jet shaping unit 4 and the locking unit 5 correspond to a mechanical cleaning of the jet shaping unit 4, since these relative movements crush and remove deposits such as lime deposits that may have accumulated in the jet shaping unit 4.
- the outlet device 1 additionally includes a spring unit 7, which is firmly connected to the locking unit 5 and supports it resiliently.
- the spring unit 7 includes four compression springs 8.
- the spring unit also includes a sealing element 9 in order to shield the spring unit 7 from the inflowing water in a fluid-tight manner.
- the spring unit 7 presses the locking unit 5 in the direction of the jet shaping unit 4.
- the internal pressure in the outlet device 1 created by the inflowing water acts against the spring force of the spring unit 7.
- the jet shaping unit 4 is therefore in the water-free state of the sanitary shower, that is, when the internal pressure is in the outlet device 1 does not exceed the definable pressure value, blocked.
- the definable pressure value can be set or adapted as desired.
- the jet shaping unit 4 has eight nozzles 10 and the locking unit 5 has eight pins 11.
- a pin 11 and an associated nozzle 10 are arranged coaxially to one another in pairs, with each pin 11 being able to be pushed in and out of the associated nozzle 10 along its own longitudinal axis.
- Each pin 11 and each associated nozzle 10 are designed to complement each other in shape, that is, each pin 11 essentially completely fills the flow channel of each associated nozzle 10 when it is pushed into the nozzle 10, so that the nozzle 10 is closed or blocked in this state and no water can flow through the nozzle 10.
- the locking unit 5 with its pins 11 is set up to open the jet shaping unit 4 with its nozzles 10 by pushing the pins 11 out of the associated nozzles 10.
- the pins 11 are pushed out of the associated nozzles 10 when the internal pressure created by the inflowing water in the outlet device 1 exceeds the pressure value defined by the number and the respective spring stiffness of the compression springs 8 of the spring unit 7.
- the locking unit 5 is also set up to lock the jet shaping unit 4 by pushing the pins 11 of the locking unit 5 into the associated nozzles 10.
- the pins 11 are pushed into the associated nozzles 10 when the internal pressure created by the inflowing water in the outlet device 1 falls below or does not exceed the pressure value defined by the number and the respective spring stiffness of the compression springs 8 of the spring unit 7.
