    Description: [0001] The invention relates to a sanitary tub arrangement having a tub wall shaped to form a tub body, which has an outer side facing the user and an inner side facing away from the user, and having at least one electronic sensor element arranged on the tub body, which is connected to an electronic control device ,
    The invention particularly relates to sanitary tub arrangements in the form of a bathtub, a whirlpool tub, a shower tray or a washbasin. As a shower tray in this context are also understood to be particularly flat versions that are continuously evacuated on at least one side to an adjacent floor area or are set up for such an arrangement, such shower trays are also commonly referred to as a shower. As well body are then also referred to designs that are almost flat.
    Conventional sanitary pan assemblies are often provided with mechanical fittings and drainage devices, then bottom valves or taps are operated mechanically by hand.
    In addition, electronically controlled inlet and outlet valves are known, which can be controlled via an input device to change the water temperature and -durchlaufmenge (Kaldewei catalog 02/2012, page 158/159). Such an input device can be kept either as a separate handpiece in the form of a remote control or used in an opening of the tub wall. A corresponding input device is also known from WO 2008/006 212 A1.
    In a separate remote control as a handset, there is the disadvantage that this can either be lost or with other measures, such as a safety line, must be secured, which complicates the handling. When used in an opening of the tub wall operating direction results in an increased design effort, because a corresponding opening must be formed or kept free. In addition, a reliable waterproof integration must be ensured to ensure the long-term function.
    Especially with sanitary tubs made of steel enamel integration is disadvantageous because at one introduced after enamelling opening the cut edge remains exposed and represents a potential vulnerability, which must be avoided in a separation and material distortion and email flaking. The introduction of a corresponding opening before enamelling is disadvantageous, because then it must already be determined whether the respective copy should be equipped with a corresponding input device. In addition, the opening is usually formed in an easily accessible, highly visible in the assembled state area. In the enameling process, in particular during the baking of enamelling, material distortions may result at such an opening, which may then possibly impair the appearance of the pan. When inserted into an opening also remain cracks, gaps or protrusions, whereby the hygiene can be impaired. Also in terms of resistance are materials that do not have the quality of steel enamel.
    Especially with regard to the individual adaptation of a sanitary tub arrangement to different user needs and the retrofitting of other technical functions, the existing solutions are not very flexible.
    Against this background, the present invention seeks to provide a sanitary tub arrangement which allows a particularly comfortable and reliable integration of at least one electronic sensor element.
    Starting from a sanitary tub arrangement with the features described above, the object is achieved in that the sensor element in the form of an acoustic surface wave sensor concealed on an uninterrupted portion of the tub wall arranged on the inside of the tub wall and for actuation from the outside through the tub wall is set through.
    According to the invention, therefore, the tub wall does not have to be opened. With regard to the preparation of the tub body no special measures must be observed. In a conventional tub body can then be determined in retrospect, whether this should be equipped with electronic sensor elements and controlled by these sensor elements safety and comfort functions.
    Since no special adjustments, recordings or the like are necessary on the tub body formed by the tub wall, the arrangement of a sensor element or a plurality of sensor elements in the form of surface acoustic wave sensors can be largely free. The position of the at least one electronic sensor element can be changed in the context of small series or from tub to tub. It is even conceivable that a tray is individually configured by a user, which is only possible with a very great effort in the systems known from the prior art.
    In the context of the invention, only a single sensor element may be provided in the form of an acoustic surface wave sensor, but preferably on the inside of the tub wall a plurality of sensor elements are provided with different functions.
    Preferably surface wave sensors are used, which have a transmitter and a receiver for surface waves and in between a measuring section in an assembly. Specifically, the surface waves from the transmitter are coupled into the well wall and detected by the receiver after propagation along the well wall.
    The propagation of the surface waves depends on the one hand on the material of the tub wall and on the other hand also from changes to the tub wall. For example, if water is present on the tub wall between the transmitter and the receiver or a user hangs up a finger, the propagating surface wave is partially attenuated and / or decoupled into the adjacent medium, whereby the amplitude of the surface wave determined at the receiver decreases. Suitable surface wave sensors or sensor arrangements are known from WO 2010/115 480 A2, wherein the detection of liquid drops is described in order to realize, for example, a rain sensor for controlling the windscreen wiper of a motor vehicle.
    In the context of the invention, the at least one sensor element can be provided both for automatic condition detection and as part of an input device, in which case a mark is expediently provided on the sensor element on the outside of the tub wall.
    In any case, it is preferably provided that the sanitary tub arrangement has a plurality of sensor elements to accommodate different operating conditions, status data at different locations and / or different user inputs.
    It is also conceivable that a single sensor or optionally one of several sensors allows both automatic state detection and an additional detection of user input, the respective specific signals are distinguished from each other.
    As part of an automatic state detection, for example, a level height, a temperature or an occupancy of the tub body can be determined by a user.
    For a level height detection of the surface wave sensor is concealed at a predetermined height arranged on the inside of the tub wall, in which case the signal changes significantly when the pent-up water in the tub body reaches the height of the surface wave sensor on the outside of the tub wall. Depending on the signal of the surface acoustic wave sensor, for example, the water supply can then be stopped and / or a bottom valve can be actuated.
    Such monitoring the level height is useful not only in bath and Whirlpool tubs, but can also be done in shower trays and sinks to prevent overflow. Especially with shallow shower trays, there is a risk that water will overflow uncontrollably in the event of a clogged drain or too low a drainage capacity, so that then the water supply is interrupted at an early stage and / or an alarm signal is output.
    With regard to a bath or spa tub and different filling heights can be predetermined by a plurality of sensors. For example, a lower fill level may be provided for small children than for adult users. In addition, it makes a difference whether the user or even multiple users are already in the tub or later board the filled tub. In the case of an electronic control system, for example, it is also possible against this background for a bath or whirlpool bath to be filled by remote control via a communication system, whereby the operation may also be considered via a "smart home" control, via the Internet or the like.
    A user can, for example, trigger the filling process already on his way home, in order then to be able to board directly on his arrival in the filled and in the realization of a temperature detection pleasant tempered bath or spa tub. Against this background, the signals from several sensors for different filling heights can also be processed by the controller depending on occupancy detection.
    The listed state information is merely exemplary. For example, even with a shower tray on the inside of the tub wall in the region of a bottom of the tub body, a sensor element may be provided which determines the presence of individual drops, the shower tray is blown so long after use by a blower until the tub body dried is.
    As already explained above, the sensor element or at least one of a plurality of sensor elements may also be part of an input device, wherein a marking is expediently provided above the sensor element on the outside of the tub wall.
    In general, the input device has at least two sensor elements, each with an associated mark, which can be provided by a corresponding number of sensor elements and markers panels with a variety of functions. The sensor elements can then be provided as part of an input device for setting different operating modes. By the sensor elements, for example, the water temperature and the amount of water can be changed, with a switch between the water outlet from a shower and a tap can be done. Even a shower head itself can be switched by an associated sensor element itself, for example, to be able to switch between a rain shower and a massage jet. In addition to the control of an electronic valve beyond other comfort functions and settings can be controlled via the input device. In particular, with an external display, for example, a menu by means of arrow keys and / or softkeys, that is, keys with context-sensitive function, possible.
    The marker can be subsequently formed in a particularly simple manner on the outside of the tub wall, wherein the position of the associated sensor element as explained above can be selected largely freely. The marking can be introduced for example by a laser or an etching in the material of the tub wall, whereby a particularly permanent marking is achieved. When using a laser, both a material removal or merely a color change can take place. In the case of a removal of material, as in the case of etching, a protective seal in the form of a lacquer layer or the like may be provided in order to protect the marking and to avoid the deposition of soiling. If, on the other hand, only a color change takes place by means of the laser, preferably in a layer below the surface, such additional measures are not necessary. In addition, the marking can also be done by a print or a sticker. This also results in the advantage that such a marker can be easily renewed or repaired. In a body made of steel enamel, the mark can also be burned into the deck enamel or post-fired.
    Any types of markings such as letters, symbols, labels, pictograms or the like are possible.
    At least the sensor element or the sensor elements, which are part of an input device, are preferably arranged in a bath or whirlpool tub, preferably at a portion of the tub wall to which there is no water during use of the tub body. In particular, the at least one marking can be formed as part of an input device to an upper, usually in the mounted state horizontal edge of the tub. In addition, the sensor element can also be arranged on the tub interior formed by the tub body above the maximum waterline. If the tub body in the form of a bathtub, a whirlpool tub or a washbasin also includes an apron, the arrangement of at least one sensor element can also be done on the apron, so then there is an operation possible.
    According to the invention, at least one sensor element is provided in the form of an acoustic surface wave sensor. The invention is based in this context on the finding that it is precisely this type of sensor that is superior to inductive or capacitive electronic sensors when used on a sanitary tub arrangement, because the transformation of electromagnetic signals into an acoustic wave proves to be particularly robust and reliable. While the tub wall in capacitive or inductive sensors is an obstacle and may affect the sensor properties, the tub wall in the inventive use of a surface acoustic wave sensor is a necessary transmission medium. With a known thickness of the tub wall so a use of surface acoustic wave sensors in different materials is possible, while inductive and capacitive sensors can not be operated by conductive materials such as stainless steel or steel enamel usually.
    According to a preferred embodiment of the invention it is provided that the tub wall, at least in the region of the at least one sensor element, ie at the uninterrupted portion, has a thickness between 0.8 mm and 9 mm. More preferably, the thickness of the tub wall on the entire tub body in the specified range.
    In particular, the tub wall may be formed of a sheet material of substantially uniform thickness. Thus, the tub wall may be formed, for example, sanitary acrylic or preferably steel enamel.
    In the context of the invention there is the advantage that the tub wall for the integration of an input device or the recording of state sensors does not have to be provided with an opening, but using the known from the prior art, inserted into an opening of the tub wall input devices often also have an ad.
    In order to communicate within the scope of the invention with a user and to confirm, for example, the input made by a user, different measures are conceivable within the scope of the invention. For example, an output device in the form of a loudspeaker, a structure-borne sound transducer or a vibration generator can be connected to the control device, wherein this output device is concealed on the inside of the tub wall. The output device is then not visible and can also be retrofitted without further notice. A corresponding loudspeaker, structure-borne sound transducer or vibration generator can, for example, be placed on the tub wall with adhesive. Entries can then be acknowledged with different vibrations, tones, tone sequences or announcements.
    Additionally or alternatively, an optical display device may be connected to the control device. As a visual display device, for example, a display or a control lamp can be provided.
    Furthermore, it is also possible that a connected to the controller lighting the tub or the environment is also used as a display device to allow, for example, an input confirmation or the transmission of other information. A tub lighting can confirm a certain input, for example by flashing or a temporary color change.
    Finally, the control device can have an interface for data communication, in particular for wireless data communication. As a wired interface, for example, a LAN port, a USB port or a connection for another BUS system into consideration. As wireless data communication, for example, WLAN, Bluetooth, Near Field Communication (NFC), an infrared interface or the like may be provided, of course, proprietary data communication devices and protocols may be used. As already described above, by means of such an interface for data communication, a far-reaching remote control of the sanitary tub arrangement and / or the integration into a "smart home" system can take place.
    The invention will be explained below with reference to a purely illustrative drawing; it shows:
    1 a sanitary tub arrangement in the form of a bathtub with a tub body,
    2 shows a detail of a tub wall of the tub body according to FIG. 1 in a perspective,
    FIG. 3 shows the detail shown in FIG. 2 in a view of an inner side of the tub wall which is concealed in the installed state, FIG.
    4 shows the detail according to FIG. 2 in a sectional side view,
    5 is a detail view of the detail A of Fig. 4,
    6 shows an alternative embodiment of the sanitary tub arrangement in the form of a shower tray,
    Fig. 7 shows an alternative embodiment of the sanitary tub arrangement in the form of a washbasin.
    Fig. 1 shows a sanitary tub arrangement in the form of a bathtub with a molded tub body 1 to a wall 2, which facing a user and visible in the installed state outside 3 and a remote from the user and hidden in the installed state and thus in Fig. 1 not visible inside 4 has. The inner side 4 with various devices arranged thereon is shown in detail in FIGS. 2 to 5.
    2, a plurality of sensor elements 5a, 5b, 5c are arranged in the form of surface wave sensors on the inside 4 of the tub wall, said sensor elements 5a, 5b each attached to an uninterrupted portion of the tub wall 2 and for an actuation of the Outside 3 are arranged through the tub wall 2 through. A first part of the sensor elements 5a, 5b is arranged on a portion of the tub wall 2 defining a tub interior, while further sensor elements 5c are located on an upper tub rim 6, which is horizontal in the mounted state.
    The various sensor elements 5a, 5b, 5c are provided for different functions. While the sensor elements 5a, 5b, 5c arranged on the downwardly extending portion of the tub wall 2 are provided for automatic status detection, the sensor elements 5c arranged on the upper edge 6 form components of an input device in order to be able to record various user inputs.
    Specifically, one of the sensor elements 5a is provided for the determination of the temperature, for which purpose this sensor element 5a is arranged in the bathtub at a height in which the water is in use.
    In the illustrated embodiment, the tub wall 2 is formed from a layer material having a substantially uniform thickness by deep drawing, wherein the tub wall 2 is preferably made of steel enamel, so that between the tub wall 2 and the water absorbed an immediate temperature compensation takes place. The corresponding sensor element 5a determines a temperature-induced change in the propagation properties of a surface wave in the tub wall 2, whereby direct conclusions about the temperature of the water within the tub body 1 are possible.
    In contrast, a further sensor element 5b is located at a height which corresponds to a predetermined filling level. As soon as the water reaches the corresponding sensor element 5b when filling the tub body 1, the signal received by this sensor element 5b changes, so that, for example, a water feed can be interrupted.
    The other sensor elements 5c on the upper edge of the tub 6, however, are provided for user input. Thus, in FIG. 1, marks 7 can be seen on the upper edge of the tub 6, which are each located above an associated sensor element 5c. The corresponding markings 7 can be formed in a particularly simple manner by a laser, an etching, an imprint or a sticker or can also be integrated into the enamelling, wherein the markings 7 can be in the form of letters, symbols, inscriptions or pictograms.
    According to the invention, the sensor elements 5a, 5b, 5c and the markers 7 can be arranged largely freely selectable in their position, resulting in a very far-reaching individual design options. In particular, individual sanitary tubs can optionally be equipped with comfort functions depending on the respective user requirements, wherein a change of geometry in small batches or even in individual sanitary tubs is possible.
    FIG. 5 shows a detailed view of one of the sensor elements 5c arranged on the upper rim 6. The sensor elements 5a, 5b, 5c are concealed attached to the inside 4 of the tub wall 2, wherein in the Fig. 5 to detect
