Description

Detailed Description of the Invention

[0001] The present invention relates to a sanitary system, in particular a sanitary element for a shower, a bathtub, a sanitary basin or another piece of furniture from the sanitary sector, which comprises at least one lighting element.The invention further relates to a sanitary system equipped with at least one such sanitary element.The invention also relates to a method for controlling the sanitary system and to the use of the sanitary system.

[0002] Modern showers and bathtubs not only offer users a better combination of beauty and functionality than ever before, but they are also a comfortable way to relax tired muscles after a long day at work or start your day feeling refreshed in the morning. To positively impact the shower experience, showers and bathtubs can be equipped with lamps that can illuminate the interior of the shower stall or bathtub.

[0003] Conventional lighting tiles, equipped with one or more light sources for effectively illuminating surfaces such as walls and ceilings, are known from the state of the art. Tiles are thin, plate-like elements made of ceramic, natural stone, glass, or cement, particularly used as wall or floor coverings. They may contain mineral additives that alter their color, translucency, or other properties. The tiles may be made of a substantially transparent material or may be at least partially transparent to light waves in the spectral range visible to the human eye. Illuminating such tiles with a light source scatters the light depending on the tile's material properties, thereby achieving, for example, lighting or optical effects. Such lighting tiles are disclosed, for example, in DE 10 2005 002 783 A1. The tiles described therein comprise a tile plate having a lower surface, on which at least one light source is provided, the light of which is directed substantially toward the lower surface of the tile plate.

[0004] However, the drawback of the latest technology is that tiles are only designed for normal interior walls and ceilings in buildings, so they cannot meet the waterproofing requirements for humid rooms. In particular, the latest technology does not meet the requirements for floor tiles in showers and bathtubs. Furthermore, lighting models are technically limited to illuminating only certain colors and shapes. Furthermore, current cutting-edge technology does not allow for easy installation. Therefore, it is necessary to overcome the drawbacks of the latest technology and provide an improved shower or bathing experience.

[0005] The object of the present invention is therefore to provide an easy-to-install hygiene element that overcomes the drawbacks of the prior art and, on the other hand, has a positive effect on the bathing or showering experience of the bathing or showering user, while also reducing the risk of slipping during use, in particular when walking on the hygiene item.

[0006] According to the invention, this object is achieved by a hygiene element having the features of independent claim 1. Advantageous further developments of the hygiene element result from subclaims 2 to 14. This object is further achieved by a hygiene system according to claim 15. Advantageous embodiments of the hygiene system are evident from dependent claims 16 to 18. This object is also achieved by a method for controlling a hygiene system according to claim 19 and by the use of a hygiene system according to claim 20.

[0007] The hygiene element of the present invention according to a first aspect of the present invention comprises an at least partially translucent, walkable glass pane, a first surface formed on a first side of the glass pane, and at least one lighting element arranged on a side thereof, the first surface being different from the first side of the glass pane, and the first surface being designed to prevent the hygiene element from slipping off, with a non-slip surface arranged or formed on the surface of the glass pane in the assembled state of the hygiene element. In particular, a user walks on the glass pane while showering or bathing, and a decorative layer is arranged between the at least one lighting element and the glass pane.

[0008] The sanitary element is preferably designed for use in a sanitary system that is integrated into or forms a shower or bathtub. The sanitary element includes a walk-in sanitary washbasin or any walk-in fixture in a sanitary area.

[0009] Preferably, the sanitary element is designed as a tile-like floor element in a shower or bathtub and is used as flooring in a wet room.

[0010] The hygiene elements are therefore intended for use in wet rooms or humid rooms. Humid rooms or wet rooms are rooms where high humidity, especially due to water vapor, frequently occurs. Examples of wet rooms in private areas include showers and bathtubs. In wet or humid rooms, the floor and bathtub regularly come into direct contact with running water. Wet rooms are also called wet cells. The hygiene elements are inherently waterproof, so that at least the respective lighting elements, preferably the decorative layer, and other surfaces of the glass panes other than the first surface are also protected from moisture.

[0011] The hygiene element is intended for use in rooms with a protection area of 0 according to DIN VDE 0100-701:2008-10. Protection area 0 is defined as the interior of the bathtub or shower tray. In the case of a shower without a tray, protection area 0 is the wet floor area and the wall area up to a height of at least 5 cm above the floor material.

[0012] At least one lighting element of the sanitary element operates with a protection class of at least IPX5. Components with IPX5 certification are considered essentially water-resistant. Preferably, they should be IPX7 certified. This means that each lighting element is essentially water-resistant and sealed against the outside. When "each lighting element" is mentioned below, this shall be understood as "at least one lighting element." Each lighting element is integrated into the sanitary element, which is permanently installed on the shower or bath floor. When assembled, only the first side, with the first surface of the glass pane, is visible and accessible to the user. The other components of the sanitary element are inaccessible in the assembled state and, if visible, are only partially visible.

[0013] Each lighting element operates at an operating voltage of up to 12 Volts AC or up to 30 Volts DC. Due to the above classification, the transformer supplying current to each lighting element is located outside the protection area 0, and the electrical supply lines are led from the sanitary element to the transformer or directly to the voltage source. Due to the low voltage, the sanitary elements are very safe. A sanitary element may consist of several lighting elements, each of which may be designed as an LED or light-emitting diode, and / or as an LED chain or LED network.

[0014] The advantage of a decorative layer placed between the lighting element and the glass pane is that when the light-emitting elements are turned on, the decorative layer is transilluminated by the light beams from each light-emitting element, creating a subjectively positive shower or bath experience for the user of the sanitary element. When a light element is switched on, it lights up and shines through the decorative layer and the glass pane, allowing the user to visually perceive the illuminated glass pane along with the image information displayed by the decorative layer. The image information can be displayed in high resolution, allowing for the projection of various motifs, pictures, and photographs that differ from the simple luminous colors and shapes of current technologies. In contrast, when a light element is switched off, it remains unlit.

[0015] The decorative layer is designed so that when the light-emitting elements are turned on, the light beams of the respective light-emitting elements are refracted, creating an optical effect when the first side of the glass pane is viewed, the optical effect being perceptually different from the pure illumination of the glass pane without the decorative layer. For example, the decorative panel may be or include an image of an object, a person, and / or a landscape, the image showing the object, person, or landscape from a particular camera's perspective. The camera's perspective may be, for example, a bird's-eye view or a worm's-eye view. A bird's-eye view may be achieved, for example, by using a camera drone to take a photograph of the object, person, or landscape, giving the viewer the impression of being above the object, person, or landscape from said camera's perspective. In particular, mountain, field, city, village, or forest landscapes may be photographed from above. For example, a worm's-eye view, created by taking a photograph of the object, person, or landscape from said camera's perspective, gives the viewer the impression of being below the displayed object, person, or landscape. The decorative layer is preferably designed so that when the decorative layer and walkable glass pane are illuminated, a cross-section of the Earth's surface with a substantially uniform structure and appearance is visible on the first surface of the glass pane to which the decorative layer is attached. A user can stand and move around while using the hygiene element. Such a decorative layer provides a sense of calm to the user of the hygiene element, thereby improving the user's well-being.

[0016] The anti-slip arrangement of the hygiene element is arranged on the first surface of the glass plate or is formed on the first surface in the assembled state of the hygiene element to prevent users from moving. This means that the anti-slip arrangement increases slip resistance and improves foot safety, especially when the hygiene element is installed. The anti-slip arrangement allows the hygiene element to meet the classification requirements for anti-slip class C and the requirements for anti-slip classes in accordance with DIN 51097. The first surface of the glass plate is therefore an anti-slip surface. In particular, the anti-slip device is permanently connected to the glass plate or is an integral part of the glass plate. The anti-slip arrangement makes the first surface of the glass plate slip-resistant, allowing users to safely enter and walk on the hygiene element.

[0017] The anti-slip device can be disposed over the entire first surface of the glass pane or formed thereon. Alternatively, the anti-slip device can be disposed or formed in a spotted or partial manner on the first surface of the glass pane, i.e., only in a specific area. In particular, the anti-slip structure and waterproof design allow the hygiene element to be used in protected areas 0, i.e., in showers and bathtubs.

[0018] The sanitary element according to the invention is characterized by a simple and functionally reliable design that can be installed without any special prior knowledge. The translucent glass panes allow easy illumination, preferably of the interior of the shower or bathtub in which the sanitary element is installed. The sanitary element can be used in bathtubs, whirlpool baths, showers or swimming pools.

[0019] In the context of the present invention, "translucent" means that the glass pane and the decorative layer are sufficiently translucent or transparent to allow the user of the hygiene element on the first side of the glass pane to see the information. The decoration displayed by the decorative layer is visually perceptible through the glass pane. "Partially translucent" means that the glass pane also includes parts that are not translucent or opaque. Thus, the glass pane can be designed to be partially opaque, so that elements of the hygiene element that are located below the glass pane and that are normally visible can be hidden from the user or hidden under the glass pane.

[0020] The glass pane is preferably transparent and / or translucent. That is, the glass pane may be completely transparent or completely translucent. It is also conceivable that the glass pane is partially transparent and partially translucent. Thus, in this case, the glass pane is transparent in a defined first portion of its total area and translucent in a defined second portion of its total area. "Transparent" refers to a glass pane that transmits light and transparency. The term "translucent" refers to a glass pane that is translucent but opaque. In this case, the glass pane is at least partially translucent, and the decorative layer or displayed content underneath is revealed or only vaguely visible. Because the glass pane is specially designed with light transmission in mind, the optical effect of the decorative layer can be tailored to the user. Therefore, from the user's perspective, the decorative layer located underneath the glass pane, and in particular the content displayed thereon, may be clearly visible or only vaguely visible.

[0021] The glass pane performs the known function of a plate-shaped tile or tile plate, with a first surface of the glass pane in the assembled state of the sanitary element being flush with the surface of an adjacent tile or the first surface of an adjacent glass pane. The sanitary element allows the user to have a flat surface when entering the shower or bathtub. Therefore, the glass pane is preferably a plate-shaped, in particular rectangular, element that delimits the sanitary element towards the shower or bathroom area. The glass pane may also be a glass tile plate.

[0022] The glass panes are preferably laminated safety glass panes. Laminated safety glass is a functional glass composite consisting of at least two flat glass panes bonded together with a tear-resistant, tough, and resilient film. Laminated safety glass panels are particularly impact resistant and have excellent fragmentation resistance, and have a high residual load-bearing capacity in the event of breakage.

[0023] Preferably, the decorative layer includes a printing layer. The decorative layer designed as a printing layer is, for example, a printed plastic film, which is designed or shaped to be translucent so that the user can visually perceive the image or pattern represented by the printing layer when the lighting element is turned on. The plastic film can be laminated to an acrylic plate. The printing layer can also be composed of only an acrylic glass plate directly printed on. Therefore, the decorative layer designed as a printing layer always provides the user with the same visual image or pattern.

[0024] Alternatively or additionally, the decorative layer includes a digital image reproduction layer. The image reproduction layer can be designed to reproduce still or moving images. The image reproduction layer can therefore be a still image reproduction layer and / or a moving image reproduction layer. The image reproduction layer can be understood as a kind of screen, a digital panel capable of displaying an image (still image reproduction layer), a series of images (still image reproduction layer), or a moving image (moving image reproduction layer). The information in the image reproduction layer becomes visually available to the user of the hygiene element when the lighting elements are switched on, whereby the digital image reproduction layer is illuminated by the light beams from the respective lighting elements. The decorative layer can also be a combination of a printed layer and a digital image reproduction layer, which combines the aforementioned properties to achieve individual optical effects.

[0025] The printing layer or image reproduction layer is preferably bonded to the glass plate. In other words, the printing layer or image reproduction layer is bonded to the second surface of the glass plate. The printing layer or image reproduction layer is designed to follow the deformation of the hygiene element, particularly the glass plate, and is bonded to the glass plate. To conceal the adhesive or adhesive layer, the entire outer edge of the glass plate or the portion where the adhesive is located can be made opaque, i.e., not translucent. The second surface of the glass plate is preferably located on the second side of the glass plate opposite the first side of the glass plate. More preferably, the first surface and the second surface are formed substantially parallel to each other.

[0026] Preferably, the anti-slip device includes a plurality of micro-troughs formed on the first surface or a ceramic coating having a plurality of ridges applied to the first surface. The diameter of the micro-wells is preferably 100 to 300 μm, more preferably 150 to 250 μm, and particularly preferably about 200 μm. When the diameter of the micro-wells is 100 to 300 μm, an optimal anti-slip effect can be achieved without causing discomfort when the user walks on the glass plate.

[0027] The microwells are intended to achieve an anti-slip effect or improve anti-slip resistance. They can be formed as an orderly or random grid of dots on the first surface of the walkable glass pane. The microwells create a suction effect on the first surface. This effect is multiplied with the number of microwells, ensuring, for example, that one foot can brake steadily without a sudden stop. This increases the glass pane's stability, especially when water flows over the first surface or when standing on the first surface while walking on a sanitary element. The more microwells formed in a given area on the first surface of the glass pane, the stronger the anti-slip effect.

[0028] The microwells are preferably produced by a surface treatment method, for example, a diode laser. In this sense, the microwells are formed, for example, as a laser dot pattern at least partially on the first surface of the glass plate. The advantage of the microwells is that the transparency and hardness of the glass plate material are not changed by the surface treatment. Furthermore, the microtroughs are wear-resistant, so their effectiveness is not lost over time.

[0029] The alternative ceramic coating is applied to the glass pane at least partially, preferably over the entire surface, by a suitable coating method. The ceramic coating typically has a carrier material with multiple particles integrated into it, some of which protrude from the carrier material toward the interior of the shower or bathtub in the form of bumps, thus preventing the glass pane from slipping off or falling off when walking on it. The ceramic coating is designed to be translucent, so that the visual effect of the sanitary element, particularly the glass pane, combined with the respective lighting element in combination with the decorative layer can be visually perceived without any interference.

[0030] The present invention includes the technical teaching that at least one lighting element is embedded in or positioned on a scaffolding or acoustic insulation layer. Thus, each lighting element and the acoustic insulation layer form a coherent component, and each lighting element with the acoustic insulation layer can always be attached at a precisely defined position relative to the glass plate. Therefore, the power supply lines of each lighting element can be embedded in or attached to the acoustic insulation layer. The acoustic insulation layer is preferably connected to the glass plate in a waterproof manner to protect each light-emitting element from moisture.

[0031] According to one exemplary embodiment, the glass plate and the sound-insulating layer are arranged surrounded on all sides by frame elements. The frame elements are preferably designed to spatially limit the sanitary element together with the glass plate. In other words, the sanitary element is spatially limited on one side, i.e., on the first side of the glass plate, and on the other side by the frame elements. This facilitates transportation, storage, and assembly of the sanitary element. The frame elements may have a sheet metal shape. Sheet metal is a rolled metal product whose width and length are much greater than its thickness. The metal plate can be formed into the frame element by a suitable forming process, such as deep drawing.

[0032] Preferably, the frame element is designed in the shape of a tray or cup, which allows for an additional sealing of the sanitary element. Thus, the components of the sanitary element, in particular the glass pane, the decorative layer, the respective lighting element, and, if applicable, other components, are inserted into the bowl- or cup-shaped frame element, where they are fixed and sealed. The frame element thus protects the interior of the sanitary element from unwanted moisture penetration. If the frame element is designed in the shape of a tray or cup, it has at least one, preferably exactly one, opening through which a power supply line is routed from the sanitary element for connection to a voltage source and / or transformer. For this purpose, the opening is preferably provided with a sealing means for sealing the interior of the sanitary element from the outside atmosphere. Such a seal is at least liquid-tight.

[0033] The present invention includes the technical teaching that a sound-insulating material and / or sealing fleece is disposed on the outside of a frame element. Preferably, the sealing fleece and the sound-insulating material are connected to each other. The sound-insulating properties improve, in particular, the impact sound insulation of the hygiene element. The sealing fleece prevents accidental infiltration of liquids into the interior of the hygiene element. The sound-insulating material and / or sealing fleece is disposed at least partially around the periphery of the frame element, preferably around the entire periphery of the frame element. The sound-insulating material is designed, for example, in the form of a sound-insulating strip or tape. The sealing fleece is designed, for example, in the form of a sealing fleece strip or tape. The sealing fleece can be attached directly to the frame element or the sound-insulating material, for example, using an adhesive. For example, the sound-insulating material can be attached directly to the frame element or to the sealing fleece using an adhesive.

[0034] Alternatively or additionally, a sealant may be provided between the frame elements and the glass panels and / or, if present, between the frame elements and the acoustical layer. If an acoustical layer is present, the sealant may also be partially disposed between the glass panels and the acoustical layer. After the glass panels and their respective lighting elements are assembled together and / or onto the frame elements, the remaining gaps may be filled with a sealant so that the integrated components of the sanitary elements remain after the sealant has hardened. Alternatively, the sealant may be disposed in the aforementioned locations or between the aforementioned components in the form of a fleece or the like.

[0035] According to one embodiment, the sanitary element further comprises a drainage module at least indirectly connected to the glass pane. Because the drainage module is integrated into the sanitary element, a consistent component can be created that is assembled in the factory so that the sanitary element is tightly formed. This simplifies installation of the sanitary element. In this sense, the drainage module is preferably arranged hermetically on the glass pane. The term "hermetically sealed" means that the drainage module is arranged or attached to the glass pane so that moisture cannot penetrate into the interior of the sanitary element between the drainage module and the glass pane. The drainage module particularly comprises drainage channels that can be arranged on the side edges of the sanitary element, particularly the glass pane. Alternatively, the glass pane may be provided with a recess for accommodating the drainage module, particularly a drainage channel, drain pipe, etc. Thus, the drainage module can penetrate the sanitary element from the first surface of the glass pane, i.e., the upper side of the sanitary element that comes into contact with the user, downward in the direction of the drainage option. Therefore, components arranged below the glass pane, particularly the respective lighting elements and, if applicable, the soundproofing layer and / or frame elements, are also provided with recesses through which the drainage module is guided. Liquid on the first surface can be drained or discharged downward to a drain outlet via the drainage module. The drainage module may also include piping designed to connect the drain or drain pipe of the drainage module to a drain or sewer. Thus, the drainage module is designed to connect to a drain or sewer.

[0036] Preferably, the at least one lighting element comprises an acrylic glass sheet (also called acrylic glass, acrylic sheet, artificial glass, or acrylic glass sheet) arranged on a side of the glass sheet other than the walkable surface, and at least one end surface is illuminated by at least one lighting means. The at least one light source is or consists of at least one LED, LED chain, LED tape, or LED strip (called an "LED strip" in English). According to one embodiment, a light source in the form of an LED strip is glued or arranged on at least one end surface, preferably multiple end surfaces, and preferably all end surfaces of the acrylic glass sheet. The acrylic sheet is thus designed to be illuminated from the side, with the light diffusely scattered, causing the acrylic sheet to shine in the direction of the decorative layer. In this sense, each light source is arranged on at least one side of the acrylic glass sheet, with its surface being arranged substantially perpendicular to the first and / or second side of the glass sheet.

[0037] The acrylic glass pane is placed on the second side of the glass pane, opposite the first side, and is preferably glued thereto. If multiple lamps are provided, these can be connected to one another via connecting cables, with at least one lamp connecting cable extending outward, preferably downward, from the sanitary element. The connecting cable is thus routed to the side of the sanitary element away from the glass pane.

[0038] Furthermore, the sanitary element preferably comprises a transmitter / receiver unit connected to at least one lighting element and designed to communicate with an external input unit to change the lighting characteristics of the at least one lighting element. The transmitter and receiver unit are part of the sanitary element or are integrated into the sanitary element. By means of the transmitter and receiver unit, the lighting characteristics of each lighting element can be adjusted to the user's wishes, and the user can control the transmitter and receiver unit via the external input unit.

[0039] Each lighting element has different lighting characteristics that can be adjusted using the transmitter and receiver unit. Lighting characteristics are understood in particular as characteristics of the respective lighting element that are visually perceptible by the user of the sanitary element and that change the optical effect of the luminous glass pane. Adjustment of the lighting characteristics is performed, for example, by switching the respective lighting element on and off. Adjustment of the lighting characteristics further includes changing the color of the light, color rendering, luminous intensity, luminous flux, light quantity, brightness, and / or still or video content.

[0040] A sanitary system according to a second aspect of the present invention comprises at least one sanitary element according to the first aspect of the present invention and an external input unit. The external input unit is preferably a smartphone and / or an input module with a touchscreen and / or input keys. The sanitary system may be specifically designed as a shower or bathtub or functionally integrated into a shower or bathtub. The sanitary system may include multiple sanitary elements according to the first aspect of the present invention, in which case the transmitting and receiving units of the multiple sanitary elements may be connected to each other. Alternatively, a single transmitter and receiver unit connected to all sanitary elements for control purposes may be provided, allowing the lighting characteristics of individual lighting elements, multiple lighting elements, or all lighting elements to be affected.

[0041] The external input unit can be connected to the transmitter and receiver units by wire or wirelessly, e.g., via Bluetooth or WiFi / WLAN. This allows for easy and intuitive adjustment of the lighting characteristics of each lighting element, in particular each light source of the lighting element. The transmitting and receiving units are preferably also connected to the decoration layer, if the decoration layer is designed as a digital image reproduction layer. Therefore, the external input unit and the transmitting and receiving units are further designed so that the information displayed on the decoration layer is actively influenced by appropriate controls.

[0042] The wired external input unit is, for example, an input module with a touch screen and / or input keys. Such an input unit can be, for example, located in the immediate vicinity of a shower cubicle or a bathtub, from where it can be manually operated by a user of the sanitary system to generate input commands which are transmitted by the input unit as switching signals to the transmitter and receiver units.

[0043] Alternatively, the input unit may be a smartphone, in which case the input command is generated via a corresponding application stored on the smartphone and transmitted at least indirectly as a switching signal from the smartphone to the transceiver unit. "At least indirectly" in this context means that the input command entered into the application can be transmitted as a switching signal to the transmitter and receiver unit directly, i.e., particularly via a Wi-Fi / WLAN or Bluetooth connection, or indirectly, i.e., particularly via a cloud or internet application. Thus, the transmitter and receiver unit may include a Wi-Fi / WLAN module or a Bluetooth module. The cloud or internet application may store multiple different input commands, each linked to a specific light-emitting characteristic of each light-emitting element, in an online database. A user may select one or more desired input commands from the online database, which are then transmitted as corresponding switching signals to the transmitter and receiver unit to set the light-emitting characteristic of at least each light-emitting element, particularly the light-emitting means.

[0044] In a further development of the invention, the hygiene system further comprises an audio unit and / or a fragrance unit, and the external input unit is designed to communicate with the audio unit or fragrance unit. Such a hygiene system can provide a multisensory holistic product that combines all human senses (sight, touch, hearing, taste, smell) into a holistic shower or bath experience. The audio or olfactory unit can add further content to the image content provided by the decorative layer when the light-emitting elements are switched on, such as audio content that addresses in particular the user's sight, the user's hearing, and / or olfactory content that addresses in particular the user's sense of smell.

[0045] The audio unit is or includes a sound source, such as a Bluetooth or equivalent wireless music box or music unit, that plays sounds and / or sound content. The audio unit should also be understood as an audio output device or audio playback unit. The fragrance unit can be or include a fragrance dispenser or the like designed to fragrant the space inside the bathtub or shower compartment according to the individual design of the image content visually displayed by the decorative layer. The fragrance unit can be understood as a fragrance medium dispensing device or fragrance dispensing unit.

[0046] According to this development, the audio unit and / or the fragrance unit may each have a separate transmitter and receiver unit, which are configured to communicate with the transmitter and receiver units of the hygiene element, respectively. The input unit may be connected to the transmitter and receiver units in the manner described above. Alternatively, the audio unit and / or the fragrance unit may be designed to be controlled directly by the transmitter and receiver units of the hygiene element. By means of switching signals, the transmitter and receiver units may adapt the audio content and / or the scent, as well as the light-emitting characteristics of the respective light-emitting elements.

[0047] One embodiment of the sanitary element includes a cooling element positioned in thermal contact with the lighting element on the side of the lighting element opposite the glass plate. The thermal contact serves to transfer heat from the lighting element to the cooling element, cooling the lighting element. Cooling the light source prevents or reduces thermal degradation of the lighting element and / or other heat-sensitive components within the sanitary element. The heat transferred to the cooling element can be dissipated from the cooling element by various means. This can be done, for example, by using a coolant to cool the cooling element or by radiating heat from the side of the cooling element away from the light source. The cooling element can be in direct mechanical contact with the lighting element. Alternatively, an intermediate layer made of a thermally conductive material, such as a thermally conductive adhesive layer, can be positioned between the cooling element and the lighting element to promote adhesion between the cooling element and the lighting element. This intermediate layer can also compensate for surface irregularities between the elements.

[0048] The cooling element can cover at least half of the side of the lighting element on the opposite side of the glass pane. This already achieves a significant cooling effect of the lighting element. An even better cooling effect is achieved if the cooling element covers more than 90% of the side of the lighting element on the opposite side of the glass pane. It is preferable for the coolant to completely cover the opposite side of the glass pane. In this case, all areas of the lighting element can be directly cooled.

[0049] In a further embodiment, the cooling element includes a temperature conductor in which one or more cooling coils are embedded for conducting a coolant. The coolant can be used to maintain a constant, controllable temperature in the temperature conductor of the cooling element, while also allowing for easy and reliable dissipation of heat transferred from the lighting element. The cooling coils can be made, for example, of copper. The temperature conductor can be made, for example, of aluminum or other materials or alloys. For example, the cooling element has a thickness of 12 mm in the direction of the lighting element. Depending on the required cooling capacity, one or more, for example, two or three, individual cooling coils can be arranged within the temperature conductor. Using multiple cooling coils allows for a higher coolant throughput than a single cooling coil. The coolant can be water or another suitable coolant.

[0050] In a further embodiment, the one or more cooling coils are provided with a coolant inlet and outlet for each cooling coil, i.e., the cooling coils can be directly connected to a coolant source, for example a chilled water inlet in the sanitary area or a separate chilled water source. The cooling coil inlet and outlet can be located on only one side of the sanitary element, simplifying connection to the coolant supply.

[0051] In another embodiment, the plumbing element includes a housing containing at least the lighting and cooling elements. This results in a compact component that is easy to assemble and operate. The enclosure can be connected to the glass plate, encapsulating the rear sanitary element. The contact point between the frame and the glass plate can be designed differently depending on the embodiment, for example, by placing ribs under the glass plate that radiate away from the light source. The length of such ribs is 60 mm. The housing is made of, for example, 2.5 mm thick stainless steel, preferably U-shaped (stainless steel tray), encloses the other components of the sanitary element, and ends with a glass plate on the walk-in side. The glass plate can be made of LSG material with a thickness of 8 mm.

[0052] In a third aspect of the present invention, a method according to the present invention for controlling a sanitary system, preferably according to the second aspect of the present invention, comprises the steps of: generating a switching signal in response to an input command input by an external input unit, transmitting the switching signal from the external input unit to a transceiver unit, and controlling lighting characteristics of at least one lighting element by the transceiver unit in response to the received switching signal.

[0053] Thus, a method is provided that goes beyond the element of "light" and is designed to combine all other senses of the bather or showerer into the overall shower and / or bathing experience, thereby providing the user with a consistent overall sensory experience. The hygiene system according to the invention creates a so-called "multi-sensory shower" or a so-called "multi-sensory bath". The hygiene system according to the invention can be advantageously used as a "vitamin D shower" or "vitamin D bath". The hygiene system also improves the user's well-being, particularly by increasing melatonin, serotonin and vitamin D.
