Description

Technical Field

[0001] The present invention is an accessory for a bathroom system, which is specially used for a shower, a bathtub, a wash basin or other bathroom structures, and comprises at least one light-emitting element. The present invention also relates to a bathroom system comprising the accessory. The present invention also relates to a process for controlling and using the bathroom system. Background Art

[0002] For users, a modern shower or bathtub is not only a perfect combination of aesthetics and functionality, but also a pleasant way to relax tired muscles after a long day at work or start a new day in the morning. In order to achieve a positive bathing experience, users can equip the shower or bathtub with a light source that illuminates its interior.

[0003] For example, based on current technology, lighting tiles with one or more light sources can be installed in the bathroom for lighting on surfaces such as walls or ceilings. Tiles (especially tiles for paving walls or floors) are usually made of ceramic, natural stone, glass or cement in the form of thin plates. By mixing in minerals, their color, light transmittance or other properties can be artificially changed. Tiles can be made of basically transparent materials, or they can be translucent in the spectrum range visible to the human eye. By adding light-emitting elements to such tiles, light beams can be scattered according to the material properties of the tiles, thereby being used for lighting or achieving specific optical effects. For example, such light-emitting tiles are included in the DE 10 2005 002 783 A1 standard. The lower edge of the tile described therein is equipped with at least one light-emitting element, whose light beam is scattered downward.

[0004] However, the disadvantage of current technology is that luminous tiles can only be used for ordinary interior walls and ceilings of buildings, and cannot meet the waterproof requirements in humid environments. Current technology is particularly not compliant with the waterproof requirements of shower or bathtub floor tiles. In addition, current lighting technology is also limited in color and shape, and is complex to assemble. Therefore, it is necessary to overcome the disadvantages of the existing technology to provide users with a better bathing experience. Summary of the invention

[0005] The present invention aims to overcome the defects of the current technology and provide an easy-to-install bathroom accessory, which can provide users with a more comfortable bathing experience while also reducing the risk of slipping during use, especially when walking on the surface of the accessory.

[0006] This object is achieved by a sanitary fitting having the features of claim 1. Claims 2 to 14 describe advantageous developments of the fitting. In addition, the sanitary system of claim 15 also contributes to the achievement of the above-mentioned object. Subclaims 16 to 18 describe advantageous implementations of the sanitary system. The control process of the sanitary system of claim 19 and the use process of claim 20 also contribute to the achievement of the above-mentioned object.

[0007] A first aspect of the invention relates to an innovative bathroom accessory, comprising a glass plate which is at least partially light-transmissive and walkable. One side of the glass plate serves as a surface (first surface) and the other side is provided with one or more light-emitting elements. One side of the first surface is provided with an anti-slip structure. After installation, when a user walks on it, in particular during a shower or bath, the accessory can effectively prevent slipping. In addition, a decorative layer is provided between the light-emitting elements and the glass plate.

[0008] This accessory is particularly suitable for bathroom systems that form a shower or bathtub. It can also be used on sinks or any other walk-on surfaces in the bathing area.

[0009] The bathroom accessories are particularly suitable for laying shower floors or bathtubs and for covering the floors of bathrooms.

[0010] The fitting is designed for use in wet rooms or environments. A wet room is a room with a permanently high humidity level, such as water vapor. An isolated wet area is, for example, a shower or bathtub. The floor or bathtub in a bathroom is often in contact with water. A bathroom is also known as a toilet. The bathroom fitting is essentially waterproof, so the light-emitting elements, decorative layers and other non-surface layers are protected from moisture.

[0011] According to DIN VDE 0100-701:2008-10, this bathroom accessory is suitable for use in rooms with protection zone 0. Protection zone 0 is defined as the interior of a bathtub or shower tray. For showers without a tray, protection zone 0 is the wet floor and the wall area within 5 cm above the floor.

[0012] The light-emitting elements contained in the sanitary fitting have a protection rating of at least IPX5. Components certified to IPX5 are generally waterproof. The higher IPX7 rating is ideal. The light-emitting elements are sealed externally and thus waterproof. When "corresponding light-emitting elements" are mentioned below, this means "one or more light-emitting elements". The light-emitting elements are integrated into the sanitary fitting, which is fixedly mounted in the shower floor or in the bathtub and on which the user can walk. In the assembled state, only the first surface of the glass pane can be seen or touched by the user. The user cannot touch the other components of the sanitary fitting and can only see a small part of them at most.

[0013] The working voltage of the light-emitting element is up to 12 volts AC or 30 volts DC. Due to the above classification, the transformer that provides the current to the light-emitting element is installed outside the protection zone 0. Therefore, the power line is led out of the bathroom accessory and connected to the transformer or directly to the power supply. Due to the low voltage, the bathroom accessory is very safe. The bathroom accessory can contain a plurality of light-emitting elements, each of which can be an LED, a light-emitting diode and / or an LED light string or an LED network.

[0014] The benefit of a decorative layer between the light-emitting element and the glass panel is that when the light-emitting element is on, the light illuminates the decorative layer, creating a more comfortable and enjoyable bathing experience for the user. When the light is on, the light can illuminate and penetrate the decorative layer and the glass panel, allowing the user to see the image presented by the decorative layer through the glass panel. The image resolution can be adjusted to a higher level, allowing the user to project a variety of patterns, images or photos, which is significantly different from the simple light colors and designs of current technology. When turned off, the light-emitting element will not light up.

[0015] The decorative layer is mounted in such a way that it refracts the light beam when the light is turned on, thereby creating a unique optical effect on the surface of the glass panel. Without the decorative layer, the glass panel only has basic lighting functions. For example, the decorative layer can present an image of a specific object, person and / or scenery, and display it from a specific camera perspective. Camera perspectives include bird's-eye view or upward view. Bird's-eye view (for example, by photographing a specific object, person or scenery, especially from an overhead perspective using an aerial drone) can create a visual experience for the viewer to be above the displayed object, person or scenery. It is particularly suitable for mountain, field, city, village or forest landscape. The upward view (for example, by photographing a specific object, person or scenery and using the above camera perspective) can create a visual experience for the viewer to be below the displayed object, person or scenery. The decorative layer is preferably mounted in such a way that when the light beam passes through the decorative layer and the load-bearing glass panel, the surface side of the glass panel - that is, the side where the user stands or walks when using the bathroom accessories - can expose a specific area of ​​the ground and have a substantially uniform visual effect and appearance. Such a decorative layer can provide a calming visual experience for users of bathroom accessories, thereby enhancing their comfort.

[0016] The anti-slip structure of the bathroom accessory is arranged on the first surface of the glass panel, so that when the user walks on the glass panel after assembly, it is not easy to slip. In other words, especially after the bathroom accessory is fully installed and fixed, the anti-slip structure can enhance the anti-slip performance of the glass panel and effectively improve safety. This anti-slip design ensures that the bathroom accessory meets the requirements of anti-slip safety level C and DIN 51097. The first surface of the glass panel is an anti-slip layer. The anti-slip device cannot be removed from the glass panel or it is itself part of the glass panel. The anti-slip device ensures the anti-slip property of the first surface of the glass panel, and the user can safely stand and walk on the bathroom accessory.

[0017] The anti-slip device may cover the entire first surface of the glass plate. The anti-slip device may also cover the surface of the glass plate in a dotted or partial manner, that is, only a portion of the first surface is covered. Due to its anti-slip device and waterproof design, the bathroom accessory can be used in protection zone 0 (i.e., in a shower room or bathtub).

[0018] The bathroom accessories of the present invention have a simple structure, reliable functions, and can be easily assembled without professional experience. Due to the light transmittance of the glass plate, the bathroom accessories can directly illuminate the shower room or bathtub after being assembled, especially from the inside. The bathroom accessories can be used in bathtubs, massage bathtubs, shower rooms or swimming pools.

[0019] In the context of the present invention, "translucent" means that the glass plate and the decorative layer have sufficient light transmittance or translucency, so that the user of the bathroom accessories can clearly perceive the information presented by the decorative layer through the glass plate from the surface side of the glass plate. "Partially transparent" means that the glass plate may also have translucent or opaque areas. Therefore, the glass plate may be partially designed to be opaque in order to cover or hide the components installed below it.

[0020] The glass pane is primarily transparent and / or translucent. In other words, the glass pane can be completely transparent and light-transmissive. It can also be partially transparent and partially light-transmissive. In this case, a specific part of the glass pane is transparent and another part is light-transmissive. The term "transparent" refers to a design that allows both light and vision to penetrate the glass pane. The term "light-transmissive" refers to a design that allows only light to penetrate the glass pane, but not vision. In this case, the glass pane should be translucent and the underlying decorative layer and its displayed content are only vaguely visible. By specifically adjusting the light-transmitting properties of the glass pane, the visual effect of the decorative layer in the user's eyes can be changed in a targeted manner. As a result, when the user looks through the glass pane, the decorative layer and its displayed content can be clearly visible or vaguely hazy.

[0021] The glass panel functions similarly to a conventional flat tile or tile. Once the bathroom fixture is installed, the first surface of the glass panel should be aligned with the surface of the adjacent tile or the first surface of the adjacent bathroom fixture to provide a flat, walkable surface for the user to safely step into the shower or bathtub. Therefore, the glass panel is preferably designed in the form of a plate, preferably a rectangular shape, to separate the shower or bathroom from the rest of the bathroom fixture. The glass panel can be a tile panel made of glass.

[0022] Laminated glass is the best choice for glass panels. Laminated glass is a functional glass that is a composite material consisting of at least two flat glass sheets connected by a tear-resistant and tough elastic film. Laminated glass has excellent impact resistance and fragment adhesion, and even in the case of breakage, it has a high residual load-bearing capacity.

[0023] The decorative layer is usually a printed layer. The printed decorative layer can be a plastic film with a printed pattern. It is specially designed to have a certain degree of light transmission, so that the user can clearly see the image or pattern when the light-emitting element is turned on. The plastic film can be laminated on an acrylic sheet. The printed layer can also consist of a directly printed acrylic glass plate. The decorative layer in the form of a print can present a consistent image or pattern to the user.

[0024] In addition, the decorative layer may also include a digital image layer. The digital image layer may present a static or moving image. Therefore, the digital image layer may be a static image display layer and / or a dynamic image display layer. The digital image layer may be understood as a digital panel that presents a single image (static image display layer), multiple images (static image display layer) or a moving image (dynamic image display layer) on the screen. When the light-emitting element is turned on, the information of the digital image layer is presented to the user of the bathroom accessories in a visual form. At this time, the light beam of the light-emitting element penetrates the digital image layer, thereby presenting a specific image. The decorative layer may also be a combination of a printed layer and a digital image layer, combining the different properties of the above two to achieve a unique optical effect.

[0025] The printed or digital image layer is usually glued to the glass pane. This means that the printed or digital image layer is attached to the back of the glass pane, the side that the user does not directly contact. The printed or digital image layer is attached in such a way that it can adapt to deformations of the bathroom accessories, especially the glass pane, without peeling off or being damaged. In order to hide the adhesive or bonding layer, the outer edge of the glass pane or other bonding points can be designed to be opaque. The second surface of the glass pane is the side opposite to the user contact surface. The first surface (user contact surface) and the second surface are preferably parallel.

[0026] Generally speaking, the anti-slip device includes a plurality of micropores formed on the surface of the glass plate, or a ceramic coating with a plurality of protrusions covering the first surface. The diameter of the micropores is generally 100 to 300 μm, ideally 150 to 250 μm, and optimally about 200 μm. When the diameter of the micropores is between 100 and 300 μm, the best anti-slip property can be achieved without making the user feel uncomfortable when walking on the glass plate.

[0027] The purpose of the micropores is to prevent slipping and prevent the user from falling. They can be arranged in an orderly or random manner on the first surface of the load-bearing glass sheet to form a dotted network. The micropores create a suction cup effect on the first surface. This effect is particularly pronounced due to the large number of micropores, which ensure that each foot has a firm grip on the ground and prevents slipping. In this way, the glass sheet is made safer. Even if water flows or accumulates, the user can still maintain stability when walking on it and avoid slipping. The more micropores there are on the first surface of the glass sheet, the greater the anti-slip effect. The micropores are usually formed by surface treatment processes, such as etching with a diode laser. In this case, the first surface of the glass sheet can be laser engraved to form a dotted micropore. The use of micropores also has the advantage that the material of the glass sheet does not change its transparency and hardness due to the surface treatment. In addition, the micropores have good wear resistance and do not become ineffective over time.

[0028] Another option is to partially or, preferably, completely cover the glass panel surface with a ceramic coating using an appropriate coating process. The ceramic coating substrate has a large number of particles embedded inside it. These particles partially protrude from the ceramic coating substrate towards the inside of the shower or bathtub, which effectively prevents users from slipping when walking on the glass panel. The ceramic coating is a light-transmitting structure, so when users look at bathroom accessories, especially glass panels, the visual effects produced by the light-emitting elements and the decorative layer are not affected and can be clearly presented.

[0029] The present invention includes the following technical solution: one or more light-emitting elements are embedded or installed in a pedal sound insulation layer. Therefore, the light-emitting element and the sound insulation layer form an integral part, and the light-emitting element can always be installed on the glass plate with the sound insulation layer in a precise position. The power supply line of the light-emitting element can also be embedded or installed in the sound insulation layer. The sound insulation layer should be sealed with the glass plate to protect the light-emitting element from moisture.

[0030] According to an exemplary case, a frame can be used to cover the glass plate and the sound insulation layer and fixedly installed. The frame should be installed in an integrated manner with the glass plate to form the spatial boundary of the bathroom accessory. In other words, the first surface of the glass plate and the frame element form the spatial boundary of the bathroom accessory. This makes the accessory easy to transport, store and assemble. The frame can be in the form of a metal sheet. The metal sheet is a rolling process product, and its width and length are much greater than its thickness. The sheet can be deformed into a frame element by a suitable forming process, such as deep drawing.

[0031] The frame should be designed in the form of a basin or a cup, so that the bathroom accessories can be further sealed. The other parts of the bathroom accessories, especially the glass plate, the decorative layer, the light-emitting element and other required parts, will be installed in the bowl-shaped or cup-shaped frame and fixed and sealed as needed. In this way, the frame can effectively protect the interior of the bathroom accessories from moisture intrusion. If the frame is a bowl-shaped or cup-shaped structure, it has at least one (preferably one) opening, through which the power line can be led out of the bathroom accessories to connect to the power supply and / or transformer. The opening is preferably equipped with a sealing material to isolate the interior of the bathroom accessories from the external environment, thereby achieving sealing. The sealing form should at least ensure that it is liquid-impermeable.

[0032] The present invention includes the following technical solutions: a sound insulation layer and / or a sealing cloth is arranged on the outer side of the frame element. The sealing cloth and the sound insulation layer should be connected to each other. The sound insulation layer can improve the footstep sound insulation effect of the bathroom accessories. The sealing cloth can effectively prevent liquid from penetrating into the interior of the bathroom accessories. The sound insulation layer and / or the sealing cloth at least partially surround the frame element, preferably surround the frame element in all directions. The sound insulation layer can be designed in the form of a sound insulation strip or a sound insulation tape. The sealing cloth can be designed in the form of a sealing cloth strip or a sealing tape. The sealing cloth can be directly connected to the frame or the sound insulation layer by an adhesive. The sound insulation layer can be directly connected to the frame or the sealing cloth by an adhesive.

[0033] As an alternative or in addition, a layer of sealing material can be added between the frame and the glass pane and / or (if present) between the frame and the sound insulation layer. If a sound insulation layer is present, the sealing material can also be arranged partially between the glass pane and the sound insulation layer. After the glass pane and the corresponding lighting element have been assembled, the sealing material can be injected into the gap between them and / or between them and the frame. In this way, the sealing material will become an integrated part of the bathroom accessory after curing. The sealing material can also be arranged in the form of a sealing cloth at specific locations or in the gaps between the above-mentioned components.

[0034] According to one embodiment, the sanitary fitting further comprises a drainage module, which is at least indirectly connected to the glass plate. The drainage module is integrated into the sanitary fitting and is constructed as a coherent whole. The component can be assembled at the factory to ensure that the sanitary fitting has good sealing. At the same time, the installation process of the sanitary fitting is also simplified. The drainage module should preferably be installed in a sealed manner on the glass plate. "Sealed installation" means that when the drainage module is arranged or fixed on the glass plate in this way, moisture cannot penetrate into the inner space between the drainage module and the glass plate. The main component of the drainage module is a drainage pipe. The pipe should be arranged along the edge of the sanitary fitting, especially the glass plate. A groove can also be provided in the glass plate to install the drainage module, especially the drainage pipe, etc. Therefore, the drainage module can penetrate downwards from the first surface of the glass plate, that is, from the upper surface of the sanitary fitting that contacts the user, until it reaches the drainage outlet. Therefore, the components below the glass plate, especially the light-emitting element and the possible sound insulation layer and / or the frame, need to be provided with an opening to allow the drainage pipe to pass through. Through the drainage module, the liquid located on the first surface of the glass plate can flow downwards to the drainage outlet, so as to be discharged or guided. The drain module may also be provided with pipes for connecting the drain trough or drain pipe in the drain module to a drain outlet or sewage system. The drain module should be connected to the drain system or sewage system.

[0035] Ideally, the one or more light-emitting elements include an acrylic sheet (also known as acrylic glass, acrylic sheet, artificial glass, etc.), which is mounted on the non-user contact surface of the load-bearing glass sheet, and at least one side of the acrylic sheet is illuminated by one or more light sources. At least one light source includes one or more LED lamps, LED light chains, LED light belts or LED light strips (LED-Stripe in English). According to an exemplary case, the light source can be pasted or mounted on at least one side of the acrylic sheet in the form of an LED strip, and multiple sides are better, and all sides are the best. In this way, the acrylic sheet is illuminated from the side, and its design can further scatter the light beam, thereby illuminating the decorative layer. The light source is mounted on at least one side of the acrylic sheet, which side is substantially perpendicular to the first surface (user contact surface) and / or the second surface (non-user contact surface) of the load-bearing glass sheet.

[0036] The acrylic sheet is mounted on the second surface of the glass sheet, opposite to the first surface, usually by gluing. If there are multiple light sources, they are interconnected by a circuit. At least one connecting wire connects the light source to the outside, especially downward, and leads out of the bathroom fitting. The connecting wire should be led out from the side of the bathroom fitting where the glass sheet is not mounted.

[0037] In addition, the bathroom accessory preferably also includes a transmitter-receiver unit, which is connected to one or more light-emitting elements. The unit is used to communicate with an external input device to change the lighting characteristics of the light-emitting element. The transmitter-receiver unit is part of the bathroom accessory or is integrated in it. Through the transmitter-receiver unit, the user can adjust the lighting characteristics of the light source according to personal needs and control the transmitter-receiver unit by himself through the external input device.

[0038] The light-emitting elements have a variety of different lighting characteristics, which can be adjusted by the transmitting and receiving units. Lighting characteristics mainly refer to the characteristics of the light-emitting elements that can be visually perceived by the user, which can change the optical effect of the light-emitting glass sheet. The setting of lighting characteristics includes, for example, turning the light-emitting elements on or off. The user can also adjust other lighting characteristics, such as changing the color of the light, color rendering, luminous intensity, luminous flux, luminous amount, brightness and / or static or dynamic image content.

[0039] The second aspect of the present invention relates to a bathroom system. The bathroom system should include one or more of the above-mentioned bathroom accessories, as well as an external input unit. The external input unit generally refers to a smart phone, a touch screen, or an input module including input buttons. The bathroom system constitutes a part of a shower or bathtub, or is integrated in a shower or bathtub. The bathroom system includes a plurality of bathroom accessories that comply with the first aspect of the present invention, in which case the transmitting and receiving units of the plurality of bathroom accessories can be interconnected. In addition, a single transmitting and receiving unit can also be provided, which is connected to all bathroom accessories through control technology and can change the lighting characteristics of a single, multiple or all light-emitting elements.

[0040] The external input unit can be connected to the transmitting and receiving unit by wired or wireless means, for example, via Bluetooth or WiFi / WLAN. In this way, the user can easily and intuitively adjust the lighting characteristics of each light-emitting element, especially the light source in the light-emitting element. If the decorative layer contains a digital image layer, the transmitting and receiving unit should also be connected to the decorative layer. Such a design ensures that the external input unit and the transmitting and receiving unit can control the image information displayed by the decorative layer.

[0041] The wired external input unit generally refers to a touch screen and / or an input module including input keys. Such an input unit is located in the shower room or near the bathtub, and the user can manually operate the unit to generate input instructions, which are transmitted as control signals to the transmitting and receiving unit through the input unit.

[0042] The input unit may also be a smartphone or a similar device. The user generates input instructions through an application installed on the smartphone, and these instructions are at least indirectly transmitted to the transmitting and receiving unit as control signals. Here, "at least indirectly" means that the instructions entered in the application can be directly (i.e., immediately) transmitted via a WiFi / WLAN or Bluetooth connection, or indirectly converted into control signals through a cloud application or an Internet application, and finally transmitted to the transmitting and receiving unit. The transmitting and receiving unit may include WiFi / WLAN functionality and / or Bluetooth functionality accordingly. When using a cloud application or an Internet application, a variety of different input instructions can be stored in an online database, which are related to the specific illumination characteristics of each light-emitting element. The user can select one or more required input instructions from them. After selection, the instructions will be sent to the transmitting and receiving unit as control signals, thereby adjusting the illumination characteristics of the light-emitting element (especially the light source).

[0043] In a further development of the present invention, the bathroom system will also include an audio unit and / or a fragrance unit, and the external input unit is designed to be able to communicate with the audio / fragrance unit. Such a bathroom system can provide an overall experience of multi-sensory stimulation, combining everyone's perceptual system (vision, touch, hearing, taste, smell) to achieve a full range of bathing experience. When the light-emitting element is turned on, the image content presented through the decorative layer mainly stimulates the user's visual sense. At the same time, the audio unit or the fragrance unit can be further supplemented, especially through sound content to stimulate the user's hearing, and through fragrance to stimulate the user's smell and taste.

[0044] An audio unit is a sound source, such as a Bluetooth speaker or similar wireless music device, used to play ambient music and / or specific sound effects. An audio unit also includes an audio output device as well as a playback unit. A fragrance unit is a fragrance device or similar device designed to add a scent to a bathroom or shower cubicle that matches the image content presented by the decorative layer. A fragrance unit can be understood as a fragrance release device or fragrance distribution unit.

[0045] According to this development, the audio unit and / or the fragrance unit can each be equipped with a separate transceiver unit, and each transceiver unit can communicate with the transceiver unit of the bathroom accessory. The external input unit can be connected to the relevant transceiver unit in the above-mentioned manner. The audio unit and / or the fragrance unit can also be controlled directly by the transceiver unit of the bathroom accessory. Control signals can be sent to the transceiver unit via this input unit. These signals can not only adjust the lighting characteristics of each light element, but also adjust the audio content and / or fragrance.

[0046] In one embodiment, the bathroom fittings also include a cooling element, which forms thermal contact with the light-emitting element at the opposite side of the glass plate. The role of thermal contact is to conduct the heat of the light-emitting element to the cooling element, thereby cooling the light-emitting element. Heat dissipation of the light-emitting element can prevent or reduce aging caused by heat and / or damage to other heat-sensitive components in the bathroom fittings. The heat transferred to the cooling element can be derived from the cooling element in different ways. For example, the cooling element can be cooled by using a coolant, or heat can be radiated on the side of the cooling element away from the light source. The cooling element can be in direct contact with the light-emitting element. Alternatively, an intermediate layer with good thermal conductivity can be provided between the cooling element and the light-emitting element, which is used as an adhesive layer between the cooling element and the light source element, such as a thermally conductive adhesive layer. The intermediate layer can also compensate for the uneven surface between the elements.

[0047] The cooling element can cover at least half of the area of ​​the side of the light emitting element in contact with the load-bearing glass plate. This can already achieve a good cooling effect on the light emitting element. When the cooling element covers more than 90% of the area of ​​the side of the light emitting element in contact with the glass plate, a better cooling effect can be achieved. In the best case, the cooling element completely covers the side of the light emitting element in contact with the glass plate. In this case, all areas of the light emitting element can be directly cooled.

[0048] In another embodiment, the cooling element includes a temperature control body in which one or more cooling tubes for guiding a coolant are embedded. The use of a coolant can keep the temperature control body of the cooling element within a constant, controllable temperature range, and can easily and reliably conduct the heat transferred from the light-emitting element. For example, a copper cooling coil can be used. The temperature control body can be made of aluminum, other materials or alloys. For example, the thickness of the cooling element along the direction of the light-emitting element is 12 mm. Depending on the required cooling performance, one or more cooling pipes, such as two or three independent cooling pipes, can be arranged in the temperature control body. Multiple cooling pipes have a larger coolant flow rate than a single cooling pipe. The coolant can be water or other suitable liquids.

[0049] In another embodiment, each cooling channel includes an inlet and outlet for coolant. In this way, the cooling channel can be directly connected to a coolant supply system, such as a cold water inlet in a bathroom area or other cold water supply pipe. The inlet and outlet of the cooling channel can be arranged on the same side of the bathroom accessories, so as to more conveniently connect to the coolant supply system.

[0050] In another embodiment, the sanitary fitting further comprises a housing that can accommodate at least the light-emitting element and the cooling element. As a whole, they form a compact structure that is easy to assemble and activate. In this case, the housing is connected to the glass plate, thereby enclosing the back of the sanitary fitting. The contact point between the housing and the glass plate can be specifically designed according to different embodiments. For example, ribs that extend radially from the light source outward can be arranged under the glass plate. The rib length can be 60 mm. The housing is made of 2.5 mm thick stainless steel, preferably in a U-shaped design (stainless steel tray), in which the other components of the sanitary fitting are wrapped, and docked with the glass plate on the side that the user contacts. The glass plate can be made of 8 mm thick laminated glass (LSG) material.

[0051] The third aspect of the present invention relates to a control method, which is applicable to the bathroom system of the second aspect, and the specific steps are as follows: first, a control signal input by a user is generated through an external input unit; then, the signal is sent from the external input unit to a transmitting and receiving unit; finally, the transmitting and receiving unit adjusts the lighting characteristics of one or more light-emitting elements according to the received control signal.

[0052] This control method aims to integrate all the bather's senses into a complete bathing experience, not just the "light" element. This creates a coherent overall sensory experience for the user. The bathroom system of the present invention realizes the so-called "multi-sensory shower" or "multi-sensory bath" experience. This bathroom system provides a beneficial "vitamin D shower" or "vitamin D bath". The bathroom system can also improve the user's physical and mental health, especially by increasing the level of melatonin, serotonin and vitamin D, enhancing the user's overall health experience. The bathroom system realizes a multi-sensory overall bathroom experience. The bathroom system opens up a multi-sensory, all-round bathing experience.

[0053] According to a second aspect of the present invention, the bathroom system is particularly suitable for a shower room or a bathtub. It can be the shower room itself, or a part integrated in the shower room. It can also be the bathtub itself, or a part integrated in the bathtub.

[0063] Figure 1 A qualitative cross section of the sanitary fitting 1 of the present invention is shown. The sanitary fitting 1 can be used as a floor covering for a shower or bathtub, for example installed on the floor of a shower or bathtub, arranged side by side with floor tiles or floor boards.

[0064] The sanitary fitting 1 comprises a load-bearing glass plate 2 which is at least partially transparent and is mounted in a frame 11, the frame element being made of aluminum. A first side S1 of the glass plate 2 comprises a first surface 2a on which a user can walk. Inside the sanitary fitting 1, i.e., on a second side S2 of the glass plate 2 opposite to the first side S1, a lighting element 3 is mounted, which comprises an acrylic plate 3a and a light-emitting element 3b. The first side S1 and the second side S2 are located on either side of the glass plate 2, respectively.

[0065] An anti-slip device 4 is provided on the first surface 2a of the glass plate 2. After the bathroom accessories 1 are installed, the device can ensure that the user will not slip when walking on the glass plate 2, especially during showering or bathing. Figure 1 The anti-skid device 4 includes a plurality of micropores 7 formed on the first surface 2a. The diameter of the micropores 7 is 100 μm to 300 μm, preferably 100 μm to 200 μm, and optimally 200 μm to 300 μm. In addition to forming the micropores 7 on the first surface 2a, the anti-skid device 4 may also be a ceramic coating 8 coated on the first surface 2a, with a large number of protrusions 9 on the coating.

[0066] A decorative layer 16 is provided between the lighting element 3 and the glass plate 2. The decorative layer 16 may consist of a printed layer 5 and / or a digital image layer 6. In this case, the decorative layer 16 is adhered to the second surface 2b of the glass plate 2. The printed layer 5 or the digital image layer 6 may be adhered to the glass plate 3. The glass plate 2 is a laminated safety glass consisting of at least two sheets of flat glass connected by a tear-resistant and elastic film (indicated by a dotted line in the glass plate 2). The glass plate 2 is transparent so that the decorative layer 16 can be seen through the glass plate 2 when a user steps into the bathroom fitting 1 and the lighting element 3 is switched on. The decorative layer 16 is located in the laminated structure of the bathroom fitting 1, sandwiched between the glass plate 2 and the acrylic plate 3a of the lighting element 3. The light-emitting element 3b is arranged on the edge of the acrylic plate 3a and can illuminate the acrylic plate 3a when switched on.

The bottom surface of the acrylic plate 3a is not in contact with the sealing material 10, but is arranged on the foot-sound insulation layer 17. The sound insulation layer 17 completely or partially relieves the load generated by the user, thereby increasing the service life of the bathroom accessory 1. The sealing material 10 is located between the frame 11 and the structure composed of the glass plate 2, the decorative layers 5, 6, 16, the lighting element 3 and the foot-sound insulation layer 17 as a seal or buffer layer, which not only plays a waterproof sealing role, but also acts as a flexible buffer layer under thermal load to compensate for changes in material properties.

[0068] A sound insulation layer 13 and / or a sealing cloth 14 are also provided on the outer side 12 of the frame 11, wherein the sealing cloth 14 and the sound insulation layer 13 are connected together. The sound insulation layer 13 also improves the footstep sound insulation effect of the bathroom accessory 1 by reducing the sound transmission between the bathroom accessory 1 and the surrounding environment or components. The sealing cloth 14 can effectively prevent liquid from penetrating into the interior of the bathroom accessory 1.

[0069] according to Figure 1 The sanitary fitting 1 according to the invention further comprises a drainage module 15, which is at least indirectly connected to the glass plate 2. This makes it easier to install the sanitary fitting 1 in a shower or bathtub.

[0070] Figure 2 Shows the basis Figure 1 The qualitative perspective view of the bathroom fitting 1 of the present invention is shown, wherein the bathroom fitting 1 presents Figure 1 The various levels in the description (dashed lines). In addition, Figure 2Ventilation holes 18 are also shown, which are very important during the manufacturing process to prevent air bubbles from forming after the layers are compressed, as air can escape through the vent holes 18. The vent holes are located in the frame element 11. Due to the way the transparent or translucent layers are displayed, the vent holes may give the illusion that they are present in the other layers. The number and size of the vent holes 18 can vary. In this example, the bathroom fitting 1 has four vent holes 18.
