Description

The present invention relates to a sanitary device that can be used in particular by people in sanitary rooms, such as bathrooms, for showering, bathing and/or personal hygiene.

Through everyday use of a shower, wastewater components (e.g. siphon, shower drain, hair strainer container) quickly become clogged with impurities. Debris adheres to surfaces and reduces the draining capacity of the wastewater component or clogs it, which can lead to water damage. In addition, the impurities can lead to poor water quality.

When using sanitary facilities such as showers or bathtubs, high water consumption can occur. For this reason, sanitary facilities are known in which at least part of the water used (gray water) can be returned to the sanitary facilities in order to reuse the water used.

If the used water is then sent to the wastewater, the water quality no longer plays a role at this point. In contrast, if the water is to be reused (recycled), the water quality is crucial for the success of such an application. Continuous bacterial growth caused by biofilm deposits in the drainage system can lead to health problems for the user.

The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and to provide a sanitary facility, in particular designed as a recycling shower, in which at least part of the surfaces carrying the gray water can be continuously cleaned.

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

• - eine Abgabeeinrichtung für eine Flüssigkeit (insbesondere Wasser);
• - ein Becken mit einem Abfluss für die Flüssigkeit; sowie
• - eine Mischeinrichtung, durch die ein Warmwasser und ein Kaltwasser zu einem temperierten Mischwasser mischbar sind, wobei das Mischwasser der Abgabeeinrichtung über eine erste Leitung zuführbar ist.

A sanitary facility is proposed, at least comprising:

• - a delivery device for a liquid (in particular water);
• - a basin with a drain for the liquid; as well as
• - a mixing device through which hot water and cold water can be mixed to form a tempered mixed water, the mixed water being able to be fed to the delivery device via a first line.

A disinfection device that emits UV rays (ultraviolet rays) is arranged in the basin and can be used to treat at least part of the basin and the liquid therein.

In general, UV disinfection is used to treat water or liquids. For this purpose z. B. UV-C LEDs are used to irradiate the water. This kills certain germs and bacteria in the water. In the present case, an application of this disinfection method is proposed specifically in drain systems (i.e. systems of sanitary facilities comprising a drain, e.g. basins or components connected to them) in order to disinfect the liquid there and prevent the formation of biofilm (breeding medium for bacteria). By integrating UV-C LEDs into a basin or a drainage system, the adhesion and growth of bacteria on the component surfaces can be largely contained or even eliminated. If the basin or drain is filled with liquid, the liquid itself is also disinfected. The UV disinfection thus increases the hygiene of the entire system, especially in sanitary facilities with a circulation device, through which at least part of the liquid drained through the drain or in the basin is returned to the dispensing device as circulating liquid.

The radiation used in UV disinfection is usually UV-C radiation with a wavelength of 100 to 280 nanometers.

By using UV disinfection, the frequency of manual cleaning of the drain or basin can be greatly reduced or eliminated. It is possible to avoid using chemical cleaning agents. With regard to recycling showers, i.e. with circulation devices, in contrast to conventional UV systems, the hygiene in the reservoir (basin or drain) can be improved using the continuous process. As a consequence, the water quality of the recycled water is better. By integrating UV radiation sources into the pool or drain system no additional components are required for disinfection.

The disinfection device can be activated or deactivated in particular via a moisture sensor or a fill level sensor. This means that the at least one UV radiation source can be activated by the presence of liquid in the pool. Alternatively or additionally, the disinfection device can be activated or deactivated by actuating the mixing device. Alternatively or additionally, manual actuation of the disinfection device can be provided.

The sanitary facility is in particular a facility for a person's personal hygiene. For this purpose, the sanitary facility can be designed, for example, in the manner of a shower or bathtub and/or arranged in a sanitary room, such as a bathroom. The sanitary facility can also be used for therapeutic applications. The sanitary facility has at least one dispensing device for a liquid. The at least one dispensing device can in particular be a shower, overhead shower, hand shower, nozzle and/or outlet opening. A liquid, in particular water, can be dispensed into (at least) one basin of the sanitary facility through at least one delivery opening of the delivery device.

The basin can in particular be designed in the manner of a shower tray or a bathing basin. Furthermore, the basin can in particular be arranged or fastened in a stationary manner, for example on a building floor. The pool can have (at least) one drain for the liquid, particularly on one pool floor. The liquid can be fed, in particular, to a public sewer system via the drain. It is possible for a single basin or drain to be assigned to several delivery devices, but this is not absolutely necessary.

The sanitary facility further comprises a mixing device through which hot water and cold water (possibly also a circulating liquid) can be mixed to form a tempered mixed water. The hot water and the cold water are each fresh water and can be mixed by the mixing device to form mixed water with a desired mixed water temperature. A hot water temperature of the hot water can in particular be a maximum of 90 ° C (degrees Celsius), preferably 25 ° C to 90 ° C, particularly preferably 55 ° C to 65 ° C, and / or a cold water temperature of the cold water, in particular a maximum of 25 ° C (Celsius), preferably 1 °C to 25 °C, particularly preferably 5 °C to 20 °C. The desired temperature of the liquid dispensed via the dispensing device can be, for example, 30 ° C to 50 ° C, preferably 35 ° C to 45 ° C, particularly preferably 35 ° C to 40 ° C.

The hot water can be supplied to the mixing device, for example, from a hot water source, such as a boiler, a (private and/or local) thermal solar system or a heat pump, via a hot water pipe and/or the cold water from a cold water source, such as a building water connection, a public one Water supply network or a (private/local) well, can be supplied via a cold water pipe. The hot water pipe and/or cold water pipe can at least partially be designed in the manner of a pipeline. Furthermore, the hot water pipe and/or cold water pipe can run at least partially through a building wall and/or a building floor. The mixing device can have a hot water inlet for the hot water and/or a cold water inlet for the cold water. The hot water pipe can be connected to the hot water inlet and/or the cold water pipe can be connected to the cold water inlet. In addition, the mixing device can be arranged at least partially in the building wall or the building floor.

The first line (mixed water line) can be at least partially designed in the manner of a pipeline and/or hose line.

In particular, the disinfection device comprises at least one or a plurality of UV radiation sources. The respective beam source is arranged so that its UV rays impact at least part of the surfaces of the pool.

In particular, the sanitary device comprises a circulation device for returning at least part of the liquid that has flowed through the drain or is in the basin as circulating liquid to the dispensing device.

The circulation device includes in particular a second line, which can be at least partially designed in the manner of a pipeline. Furthermore, the second line can run at least partially through a building wall and/or a building floor.

The liquid dispensed via the dispensing device can be returned to the dispensing device (as circulating liquid) via the circulation device. For this purpose, at least part of the liquid that has flowed out via the drain or is in the basin is conveyed back to the dispensing device as circulating liquid by the circulation device.

The temperature of the circulating fluid can fluctuate. The circulating liquid is fed in particular to the mixing device and can be mixed together with the cold water and/or the hot water to form a tempered mixed water.

In particular, the second line is exclusively flowed through by circulating fluid.

The temperature of the mixed water can be increased by the mixing device by adding hot water and/or reduced by adding cold water. The hot water and/or cold water is in particular fresh water, which in particular has not yet been used by the sanitary facility or has not yet been dispensed via the at least one delivery device.

The sanitary facility can in particular be operated in different operating modes. So can e.g. B. only fresh water can be used. Furthermore, only circulating liquid can be used, with the temperature of the liquid dispensed via the dispensing device then e.g. B. corresponds to the temperature of the circulating fluid. Furthermore, a mixed operation can be provided, in which fresh water and circulating liquid are used at least temporarily at the same time. The temperature of the liquid dispensed via the dispensing device is then regulated in particular via the mixing device.

In particular, the circulation device has a suction port which is arranged opposite the basin in such a way that liquid in the basin can be sucked in via the suction port. A flow path of the liquid in the basin towards the intake port can be affected by the UV rays. In particular, all possible flow paths of the liquid in the basin towards the suction port can be exposed to UV rays or are exposed to it during operation of the disinfection device. In particular, an area around the intake port is specifically targeted by the UV rays.

In particular, the basin has a drain area and a stay area, the drain being arranged in the drain area. The drain area is arranged adjacent (or spaced apart, but then in fluid communication for the liquid) to the area where a user of the sanitary facility is located. The UV rays affect at least the drainage area and especially not the occupied area.

The lounge area is the area in which a user of the sanitary facility usually stays when it is in operation. In contrast, the drainage area is an area in which the user is not currently or cannot be (due to the spatial design or arrangement). This can prevent damage to a user caused by UV radiation.

In particular, the at least one or the majority of UV radiation sources is arranged on a cover element of the drain area, the cover element being arranged above a maximum fill level of the basin. This means that the at least one UV radiation source can be arranged outside the liquid at any time when the sanitary facility is in use. It is therefore not absolutely necessary for the UV radiation source to be sealed against the liquid. On the other hand, this also makes it easier to expose the liquid and the surfaces exposed to the liquid to UV radiation.

In particular, the sanitary device comprises a circulation device for returning at least part of the liquid that has flowed through the drain or is in the basin as circulating liquid to the dispensing device. The circulation device has a suction port through which liquid in the basin can be sucked in. The intake port is arranged in particular within the drain area, i.e. not in the occupied area.

A basin for the sanitary facility described is further proposed, with a UV ray-emitting disinfection device being arranged in the basin, through which at least part of the basin and the liquid contained therein can be treated.

In particular, the basin has a drain area and a stay area, the drain being arranged in the drain area. The drain area is arranged adjacent to the lounge area of a user of the sanitary facility. The drain area comprises a cover element which is arranged above a maximum fill level of the basin, with at least one UV radiation source being arranged on the cover element.

In particular, the basin has a suction port for a circulation device.

A drain area assembly for the basin described is further proposed, comprising at least a floor element with the drain of the basin and a cover element which is arranged above a maximum fill level of the basin, with at least one UV radiation source being arranged on the cover element.

The drain area assembly is in particular a component that can be manufactured separately from the lounge area of a pool and can be assembled together with the lounge area to form the pool. The drain area assembly is usually arranged laterally (horizontally or vertically, then below) adjacent to the stay area so that liquid can flow towards the drain or a reservoir of liquid can be formed for the suction port

In particular, the drain area assembly has a suction port for a circulation device.

The comments on the sanitary facility apply in particular equally to the basin and the drain area assembly.

As a precaution, it should be noted that the number words used here (“first”, “second”,...) primarily serve (only) to distinguish between several similar objects, sizes or processes, i.e. in particular no dependency and/or order of these objects, sizes or prescribe processes to each other. If a dependency and/or sequence is required, this is explicitly stated here or it will be obvious to the person skilled in the art when studying the specifically described embodiment. To the extent that a component can occur multiple times (“at least one”), the description of one of these components can apply equally to all or part of the majority of these components, but this is not mandatory.
