The invention is based on the technical problem of providing a sanitary shower/washing facility of the type mentioned at the outset, which is able to offer the user showering/washing comfort that is further improved compared to the prior art explained above or to offer him a showering experience that meets his current specific needs.

The invention solves this problem by providing a sanitary shower/washing facility with the features of claim 1.

The sanitary shower/washing facility according to the invention includes a water delivery unit that is configured to deliver water at a shower/washing location, and a situation detection unit that is configured to collect current showering/washing situation data and a user identification unit that is configured to identify a user located at the showering/washing location, and a user condition detection unit that detects at least one user condition parameter that detects at least one user condition parameter that is indicative of a current condition of the user at the showering/washing location, including the possibility of direct sensory detection and/or indirect detection from information from external sources, such as smartphones etc. The showering/washing situation data include corresponding current user identification data and current user status data. The shower/washing device also has a shower/washing process control unit that is configured to store shower/washing program data and to generate shower/washing program suggestion data variably depending on the showering/washing situation data currently recorded by the situation recording unit. Furthermore, the shower/washing process control unit is configured to define a current showering/washing program using the shower/washing program suggestion data and to control a respectively activated showering/washing process with the water dispensed from the water dispensing unit according to the current showering/washing program defined.

The shower/washing device characterized in this way offers the user a high degree of showering/washing comfort and offers the prerequisite for great variability and optimal adaptability of the shower/washing process desired or suitable for the respective user. For this purpose, the situation detection unit uses its user identification unit to identify the user who is at the shower/washing location and for whom a shower/washing process is to be activated. For this identification, the user identification unit is implemented in any of the known implementations, eg using a camera, an identity transmitter or using a requested user input with which the user can communicate his identity in a suitable manner. With the help of its user status detection unit, the situation detection unit detects the at least one user status parameter by sensors and/or from information from external sources, whereby the shower/washing facility is informed about the current status of the user at the shower/washing location.

Accordingly, the showering/washing situation data recorded by the situation recording unit contains the relevant current user identification data and current user status data. The shower/washing process control unit is then able to variably generate the shower/washing program suggestion data as a function of the showering/washing situation data currently recorded by the situation recording unit and, using the same, to define the current showering/washing program for the user and to control the water dispensing unit accordingly.

Thus, the shower/washing facility according to the invention has the ability to provide the respective shower/washing user with a showering/washing process that does not need to run according to a fixed shower/washing program, e.g. Consequently, the user does not need to actively take care of changing a shower/washing program that he has previously created and stored in the system, or be satisfied with the previously stored shower/washing program. In the present case, the shower/washing system automatically takes into account the current state of the user or a change in his current state compared to a state assumed when creating a possible earlier shower/washing program and adjusts the current showering/washing program accordingly.

In a further development of the invention, the water delivery unit is configured for the variably controllable change of at least one shower/washing parameter, which belongs to the group consisting of parameters relating to shower jet type, shower jet direction, shower water temperature, shower water pressure, shower water flow rate, shower water additives, humidity, audio performance, video performance, lighting effect and shower/washing location heating. Depending on the desired functionality and implementation, the water dispensing unit is thus able to provide the user with an optimal showering/washing effect.

In a development of the invention, the shower/washing process control unit is configured to make the shower/washing program suggestion data user-accessible and in response to a user confirmation input as showering/washing program data for the current shower/wash program. This offers the user the option of accepting the shower/washing program suggestion generated by the system by confirming it or rejecting or modifying it.

In one development of the invention, the at least one user status parameter includes at least one user-physical parameter and/or at least one user-environment-related parameter. In this way, the corresponding user-relevant influencing variables for the optimal design of the current showering/washing process can be taken into account. The user-physical parameters can be detected by corresponding conventional sensor units, such as are also known from the health and fitness sector and the smart home sector. The parameters related to the user environment can also be detected by corresponding conventional sensor units, as are known to the person skilled in the art for this purpose.

In one embodiment of the invention, the at least one user physical parameter is one from the group consisting of parameters relating to heart rate, blood pressure, blood oxygen content, respiratory rate, body temperature and body weight. This represents advantageous factors to be taken into account for the design of an optimal current shower/washing process and, last but not least, also health-related factors.

In one embodiment of the invention, the at least one user-environment-related parameter is one from the group consisting of parameters relating to wake-up time, time of day, day of the week, fitness activity, room temperature, outside air temperature, and weather data. In this way, the corresponding influencing variables from the user's environment can be taken into account for the optimal design of the current showering/washing process.

In a development of the invention, the shower/washing process control unit is configured to store a plurality of different basic scenario shower/washing programs and to take into account the stored basic scenario showering/washing programs when generating the recommended shower/washing program data. This ability of the shower/washing process control unit enables the storage of typical basic scenarios as a kind of rough preset for the desired shower/wash program. Such basic scenarios can be, for example, a fitness shower/wash program, a health shower/wash program, a pleasure shower/wash program, a care shower/wash program and/or a quick shower/wash program. In this case, the shower/washing facility can select one of these basic programs depending on the recognized user and the detected current shower/washing situation data and, possibly making suitable modifications, can propose a shower program or washing program that is optimal for the situation by generating the corresponding shower/washing program suggestion data.

In a development of the invention, the shower/washing process control unit is configured to determine historical showering/washing activity data and to take the historical showering/washing activity data into account when generating the recommended shower/washing program data. With this capability of the showering/washing process control unit, the showering/washing device can advantageously use previous showering/washing activities of the respective user to determine the currently optimal showering/washing process for him.

In a development of the invention, the shower/washing process control unit is designed to be self-learning based on the historical showering/washing activity data and is configured to take the learned data into account when generating the suggested shower/washing program data. This ability of the shower/washing process control unit further contributes to the fact that the shower/washing device is in the best possible way able to suggest the shower/washing program that is optimal for the respective user at the moment. Due to the self-learning ability of the shower/washing process control unit based on the user's previous showering/washing activities, it can empirically recognize any preferences of the user in this way and use them from the outset for future shower/washing program suggestions.

In a development of the invention, the shower/washing process control unit is configured for user input of showering/washing preference data and for considering the showering/washing preference data when generating the suggested shower/washing program data. In this way, the user can advantageously specify or inform the shower/washing device of showering/washing preferences, ie one or more shower/wash programs he generally prefers. The showering/washing preferences can also include individual objectives, such as strengthening the immune system, promoting blood circulation, pain relief, wellness effects, etc. This in turn can support the showering/washing facility in determining the optimal current showering/washing program for the user in the best possible way.

Advantageous embodiments of the invention are shown in the drawings. These and other advantageous embodiments of the invention are explained in more detail below. Here show:

1

a schematic block diagram of a sanitary shower facility and

2

a flowchart to illustrate the process of the shower device according to 1 executable shower process.

In the 1 The sanitary shower facility shown schematically only with its components of interest here has a water dispensing unit 1 , here specifically a shower water dispensing unit, a situation detection unit 2 and a shower process control unit 3 . The water dispensing unit 1 is configured to dispense water, here specifically shower water, at a shower location 4, e.g. a shower cubicle, a shower room or the like. The situation detection unit 2 is configured to collect current shower situation data Dsd and includes a user identification unit 2a and a user status detection unit 2b, here using a user status sensor system as an example.

In a corresponding embodiment, as shown, the water delivery unit 1 includes a delivery end part 1b and a delivery control part 1a driving this. The dispensing end part 1b typically comprises one or more shower head units as well as optionally conventional terminals for producing audio, video and/or light effects and/or scent effects. The delivery control part 1a includes suitable associated, conventional control components, such as controllable valve units, etc.

The user identification unit 2a is configured to identify a user 5 located at the shower location 4 and provides corresponding user identification data Bid. For this purpose, the user identification unit 2a can contain, for example, a camera or a user input interface at which the user 5 can identify himself or a reading device for an ID transmitter carried by the user 5 . With this user identification, the user 5 does not necessarily have to be at the shower location 4 itself; instead, he can, for example, also be in another room in his apartment.

The user status detection unit 2b detects at least one user status parameter indicative of a current status of the user 5 at the shower location 4 and provides corresponding user status data Bzd. The shower situation data Dsd accordingly include the current user identification data Bid and the user status data Bzd and are transmitted from the situation detection unit 2 to the shower process control unit 3 via an associated communication connection 6, which can be any conventional wired or wireless connection.

The shower process control unit 3 is configured to generate shower program suggestion data Dvd variably as a function of the shower situation data Dsd currently recorded by the situation recording unit 2 . It is also configured to store shower program data. Furthermore, it is configured to define a current shower program using the suggested shower program data DVD and to control a respectively activated shower process with the water dispensed from the water dispensing unit 1 according to the defined current shower program. For this purpose, the shower process control unit 3 suitably controls the water dispensing unit 1 by means of corresponding shower program control data Dpd, which are transmitted via an associated communication link 7, which can be any conventional wired or wireless connection, optionally the same connection as the communication link 6 between the situation detection unit 2 and the shower process control unit 3.

In an advantageous implementation, the shower facility contains, as in the example shown, an information channel 8 with a user interface on the user or shower location side 8a, via which the shower process control unit 3 can inform the user 5 of the generated shower program suggestion data DVD for the forthcoming shower process. The user 5 then has the option of confirming or discarding or modifying the shower program suggestion data DVD via the user interface 8a.

To activate the pending shower process, the shower process control unit 3 then controls the water dispensing unit 1 with the current shower program data Dpd, which correspond to the shower program suggestion data Dvd with any modifications desired by the user.

In corresponding versions, the water delivery unit is configured for the variably controllable change of one and preferably several shower parameters. This can include, in particular, a variable setting of the shower jet type, shower jet direction, shower water temperature, shower water pressure and/or shower water flow rate, as well as optional, additional measures peripheral to the shower, such as introducing additives, in particular fragrances, into the shower water, the performance of music or other audio effects, a video presentation, regulation of the humidity at the shower location 4, generation of light effects and temperature control of the shower location, the latter e.g. including the option of heating the shower room s and / or towels, bathrobes or the like to heat by means of radiator activation.

In corresponding implementations, the at least one user status parameter Bzd includes one or more user-physical parameters and/or one or more user-environment-related parameters. Pulse, blood pressure, blood oxygen content, respiratory rate and/or body weight can be recorded by the situation detection unit 2 as physical user parameters, so that the shower process control unit 3 can take this data into account when determining the optimal shower program. Sensor units suitable for this purpose are known per se to a person skilled in the art, which consequently does not require any further explanation here. In corresponding embodiments, the situation detection unit 2 detects parameters related to the user environment, for example those relating to wake-up time, time of day, day of the week, fitness activity, room temperature, outside air temperature and weather data. Suitable sensor or detection units for this are known per se to a person skilled in the art, which consequently does not require any further explanation here.

In corresponding embodiments, the shower procedure control unit 3 is configured to store a plurality of different basic scenario shower programs and to take the stored basic scenario shower programs into account when generating the recommended shower program data DVD. Such basic scenarios can be, for example, a fitness shower program, a health shower program, a pleasure shower program, a care shower program and/or a quick shower program. The fitness shower program can, for example, contain an initially invigorating program part, a subsequent massage program part and a final cold shower part. The health shower program can, for example, include an introductory shower section with a gentle rain shower, saline steam and/or essential oils, a subsequent shower section with alternating hot/cold showers and a final shower section with different, massaging shower jets. The pleasure shower program can, for example, include automatic control of scent, music and light effects, the use of gentle shower jets and foam additives in the shower water. The maintenance shower program can include, for example, using a soft rain shower head and adding a shampoo or body care product to the shower water. The quick shower program can be characterized by a time-effective shower process with a comparatively short duration of the shower process.

In corresponding versions, the shower process control unit 3 is configured to determine historical shower activity data and to take the historical shower activity data into account when generating the suggested shower program data Dvd. For this purpose, the shower process control unit 3 can, for example, record whether the user 5 has already frequently aborted the shower process in the past and/or readjusted the water temperature and/or changed the shower jet type and/or made modifications to the suggested shower program data brought to his attention. If the user 5 changes the water temperature from initially 38°C to 39.5°C when starting the shower, for example, the shower control unit 3 can recognize this and, in the future, the initial temperature for the shower program suggestion data for a morning shower set to 39.5 °C. Similarly, the shower facility can generate the shower program suggestion data in corresponding versions, taking into account an activity profile to be expected of the respective user, by taking into account individual and personal parameters in addition to the historical shower activity data, e.g. the time of getting up or going to bed, whether it is a working day or a day off, whether there are entries in the user's appointment calendar, whether he has planned sporting activities and if so which ones, etc.

In corresponding embodiments, the shower process control unit 3 is designed to be self-learning based on the historical shower activity data and is configured to take the learned data into account when generating the suggested shower program data DVD. As a result, the shower device is able to offer the user 5 a shower program suggestion that is adapted to his previous showering activities or modifications to the suggested program.

In corresponding embodiments, the shower process control unit 3 is configured for user input of shower preference data and for taking this shower preference data into account when generating the shower program suggestion data DVD. This enables the shower device to take into account the preferences for the execution of shower processes for the respective user 5 when generating the shower program suggestion, so that the program suggestion usually comes very close to the current wishes of the user or already corresponds to them. Preferences of this type can relate, among other things, to the type of shower spray, the water temperature, the water pressure and/or the duration of any different shower intervals or shower sections of the shower process.

2 illustrates in block diagram form the sequence of the shower device according to FIG 1 executable shower process. First of all, in an initial method step 10, the user identity and the current status of the user 5 are recorded by the situation recording unit 2. In a next step 20, the shower facility generates a historical activity profile for this user 5, taking into account the current shower situation data Dsd and, if applicable, stored shower program data, which relate, for example, to shower preferences preselected by the user 5, to individual and personal shower parameters of the user 5 in question and/or relate to previously stored basic scenarios for the shower process, a suggestion for a shower program determined to be optimal for the user 5 in the current situation.

In a next step 30, the shower device or, more precisely, the shower process control unit 3 informs the user 5 about the proposed shower program. In a subsequent step 40, the user 5 can confirm this suggested shower program or reject it or modify it with regard to one or more shower parameters.

The shower process control unit 3 then then starts the shower process and carries it out in an associated method step 50 according to the proposed and possibly modified, ascertained shower program. To do this, it controls the water dispensing unit 1 using the corresponding current shower program data Dpd.

During and after the showering process, the showering device uses the situation detection unit 2 and/or the showering process control unit 3 to record any activities of the user 5 during or at the end of the showering process as an optional system functionality in a final step 60 . With this functionality, the shower device is able to create and update a historical activity profile for the respective user 5, which can be used for the future creation of shower program suggestions for this user together with the current status data and, depending on the circumstances, other influencing variable data, such as those about the shower preferences of the user 5 and/or a basic scenario that he or she usually wants.

While the invention was illustrated above in an implementation as a pure shower device, the invention is implemented in alternative embodiments as a pure washing device with the features and functionalities corresponding to the shower device explained above or as a corresponding combined shower and washing device. In the case of the washing device, for example, a number of different shower or water delivery units can be provided at a corresponding washing area with a washbasin, eg a shower/water delivery unit for a water collection area of the shower/washing jet impinging on the washbasin and/or a unit for a shower/washing jet emitted upwards as a fountain jet from a water outlet area of the washbasin itself, e.g. an area of its water collection area, such shower jets being well suited for washing hair and/or beard, and/or a unit for a laminar jet incident from above into the water collection area of the washbasin, which is good for washing hands, for example, for cleaning teeth Etc. is suitable, with the last-mentioned shower or water dispensing unit also being able to be, for example, a conventional faucet outlet fitting.

As the exemplary embodiments shown and those further explained above make clear, the invention provides a very advantageous shower device and/or washing device which is capable of determining and executing an optimum shower/washing program for each user at any time. The shower/washing device is able to offer the user a user-specific shower/washing experience that is optimally adapted to their current circumstances. For this purpose, depending on the system design, the shower/washing facility can make use of previously defined basic programs, previously communicated user preferences, historical showering/washing activities and/or individual, previously communicated objectives, in order to determine the currently optimum showering/washing process.
