Description

Toilet seat set

description

The invention relates to a toilet seat set according to the preamble of claim 1 and a system with such a toilet seat set.

In the case of toilet seat sets with a seat and a lid, there are different approaches to supplying electrical consumers integrated therein with electrical energy.

In the document WO 2016/020409 A1, which goes back to the applicant, a toilet seat set is disclosed in which electrical consumers, for example a seat heater and a sensor, are integrated on the seat side. These consumers are supplied with power via a control unit called a technology box, which is placed on the ceramic and on which the seat and the cover are preferably mounted. The electrical contact is made via electrical lines that are routed from the electrical consumers in the seat or in the cover to the control unit. If the seat or the cover is to be removed, this line connection must first be released. Another problem with such solutions is that the line connection between the power supply and the toilet seat set must be carefully covered so that contamination is prevented.

There has recently been a trend towards integrating additional functions into the toilet seat set in addition to seat heating. As in the above-mentioned solution, a sensor for detecting the use of the toilet seat set can be provided so that, for example, an automatic closing process of the lid can be initiated after use. In addition, emphasis is placed on an attractive appearance, so that the seats are preferably thin. In DE 102016 108379 A1 by the applicant, a toilet seat set is described in which further sensors are integrated for the direct or indirect detection of physiological or health-specific parameters / vital parameters of a user. The parameter itself or a value required for calculating the parameter can be recorded via these sensors. For example, a BMI (body mass index) can be calculated from the recorded weight with knowledge of the body size. In principle, vital data such as pulse, blood pressure, body temperature, body fat percentage, blood sugar content, etc. can also be recorded using such a sensor arrangement.

The power supply for these electrical consumers and the exchange of data between the technology box and the sensors are problematic, since there is only little space left for lines / cables within the toilet seat set. Solutions are known in which the individual lines are guided through the clamp and the seat joint arrangement in the technology box. This number of lines requires a lot of installation space in an area in which dampers and actuators / motors are also arranged.

In WO 2017/029369 A1 of the applicant, a toilet seat joint arrangement is described in which the power supply / energy supply takes place via lines, with a plug part being provided in the area of a damper of the toilet seat joint arrangement, which is provided with a seat and / or cover-side plug counterpart assigned. Thus, when assembling the toilet seat set, in which the toilet seat hinge assembly is brought into operative connection with the toilet seat and the toilet lid, the electrical connection can be made relatively easily by connecting the plug part to the plug counter piece. In a preferred embodiment described in the last-mentioned document, the connection to the external power supply is then made via the ceramic-side fastening pins, so that an electrical connector is also provided in the connection area of the fastening pin to an adapter piece of the damper.

However, this version, which has been optimized with regard to assembly, also has the disadvantage described above that a high level of effort in the electrical contacting between the external power supply and the electrical consumers on the seat set.

With such solutions, the electrical consumers (seat heating, sensors) can already be integrated into the lid or seat during the pressing / injection molding process, but the cabling / line routing outside these components, especially in the area of the toilet seat joint arrangement, is still problematic.

The document DE 102010010881 A1, which can also be traced back to the applicant, shows a toilet seat set with a motor drive for opening / closing the seat or the cover. The actuator is supplied with power via the pins described above.

In the subsequently published patent application DE 102019 110281.2, a toilet seat set is described which eliminates the aforementioned problems with regard to the cabling. There, a wireless energy transmission is proposed, wherein in the seat and the cover each opposing coupling coils are arranged, which enable energy transmission between the cover and the seat. Alternatively and / or additionally, the coupling coils can also transmit energy between a ceramic and the seat and / or between a wall or a cistern and the cover. The energy supply provided in each case for the basic supply of a primary coil, that is to say a transmitter that emits energy, can be wired so that only one cable harness is sufficient to supply the electrical consumers of the toilet seat set with electrical energy. Other exemplary embodiments have electrical storage elements which are mounted in the seat and / or the cover, so that the electrical consumers still fulfill their function regardless of a permanent energy supply.

In the publication DE 202011 108948 U1, a toilet seat set is described in which the energy supply of a seat heater is also carried out by wireless energy transmission. A primary coil and a secondary coil for contactless energy transfer are integrated in a technology box and in a toilet seat. In addition, the seat has an energy store in the form of a rechargeable battery, which is charged via the secondary coil so that the seat heater can be supplied with energy via the rechargeable battery.

Such a solution is very complex, since the integration of the battery into the seat contour is problematic both with regard to the design and also with regard to the manufacturing effort.

Similar complex solutions are also described in the documents JP 2010-125241 A and JP 2009-201559 A, in each of which a contactless energy transmission is used to supply energy to a seat heater.

US 2019/0203455 A1 describes a toilet in which a primary coil is arranged on the ceramic side and the secondary coils are arranged on the seat set side. A disadvantage of such a solution is that the seating set is only designed for use with this ceramic, so that it cannot be used with other types of ceramic.

In contrast, the invention is based on the object of creating a toilet seat set and a system in which an electrical energy supply, for example for an electrical consumer, for example a seat heater or a sensor, with little device and assembly effort regardless of external circumstances inside the toilet -Seat set is guaranteed.

This object is achieved by a toilet seat set with the features of claim 1 and a system with the features of claim 13.

Advantageous further developments of the invention are the subject of the subclaims.

The toilet seat set according to the invention has a toilet seat and a toilet lid (hereinafter referred to as the seat and lid) which are pivotably connected to a technology box. The technology box can be connected with ceramic-side fasteners, preferentially connected. The toilet seat set is designed with at least one electrical consumer, for example a seat heater, sensors, motors and / or actuators, which are energized via a device for power supply. The device for power supply has an energy transmission device which is designed for wireless / contactless energy transmission.

According to the invention, the energy transfer takes place between the technology box and the seat, so that there is no need for a wired connection in this critical area with regard to splash water and dirt. It is particularly advantageous that the technology box is part of the toilet seat set. Only the technology box must be supplied with externally supplied electrical energy, which can be done via simple cabling in a rear area of the technology box, via the ceramic-side fastening means of the technology box, or via a further wireless energy supply.

According to the invention, a transmitter coil is arranged in the technology box and a receiver coil is arranged on the seat side.

According to the invention, a carrier is arranged at least in sections in the seat. This carrier can be designed according to the shape of the seat, so that it is integrated into the seat so that it is invisible from the outside. The carrier is preferably covered by the seat and cannot be seen by the user. The carrier can in this case preferably serve as a holder for the aforementioned electrical loads or parts of the energy transmission device, in particular the receiver coil, and / or be provided as a stabilizing element in the seat.

The receiver coil can be attached to or in the carrier in a variety of ways. Embedding the receiver coil in the carrier is just as conceivable as an attached version or a version glued to the carrier. The receiver coil can also be received between the seat and the carrier. It is therefore arranged in the area of the carrier. The energy transfer between the technology box and the seat is preferably carried out inductively. An inductive energy transfer can be implemented using coupling coils, for example. These are preferably shielded from the user and from splashing water.

In an advantageous embodiment, the carrier is pressed with the seat. This pressing can be integrated into the usual manufacturing process of seat manufacture without requiring a great deal of effort. It is known from the prior art to press seat heaters in the production process with the seat so that no new work step has to be carried out in production.

As explained above, according to the invention, the carrier can carry at least one further electrical consumer, for example a seat heater, sensors such as a receipt sensor, vital parameter sensors, distance sensors or, however, also lamps or the like.

In one embodiment of the invention, the carrier is designed following the seat contour. This can be done, for example, in such a way that the carrier forms a type of core of the toilet seat.

A particularly stable construction is obtained if this carrier extends into the clamp of the toilet seat. This makes it possible to manufacture the toilet seat with a minimal overall height.

The carrier can be designed with protruding receptacles for fixing a sleeve in position or for attaching buffers.

In a particularly preferred embodiment of the invention, a deodorizer is integrated into the technology box, which is preferably controlled as a function of the signal from a receipt sensor, so that the deodorizer is operated to improve the air after leaving the toilet seat. Such a solution has the advantage that all comfort and functional parameters of the toilet seat set are integrated in the seat, the lid and / or the technology box, so that on the ceramic side or on the room side, apart from the power supply, no individual adjustments are required.

In a particularly convenient solution, a swivel drive for the seat and / or the cover can also be integrated into the technology box, which is also supplied with electrical energy via the energy transmission device.

It is particularly preferred if the technology box has a housing section facing the seat and sloping down towards a ceramic. This housing section is also referred to below as an inclined housing section.

For reasons of practicality and an attractive appearance, it is advisable for the inclined housing section to extend below the seat. In other words, the inclined housing section extends from a basically box-shaped housing section in the direction between the ceramic and the lowered seat. This inclined housing section particularly preferably has a stepped design, wherein the steps can be rounded. Due to the inclined and stepped design, the inclined housing section can be integrated into the overall appearance of the toilet seat set in a particularly elegant way. A first step of the inclined housing section preferably begins at a small distance from a rear area of the seat, so that only a narrow gap remains between the seat and the technical box when the seat is closed. A second step, following the shape of the seat, takes place at a lower rear end of the seat, so that the inclined housing section extends below the seat at a small distance from the seat. This extension preferably ends below the seat, so that the inclined housing section does not protrude visibly from under the seat. An outlet of the deodorizer can also be integrated into this area.

In a preferred development, the transmitter coil is arranged in the inclined housing section of the technology box. The transmitter coil is thus arranged directly below the seat. It is particularly preferred if the transmitter coil is arranged in or on a wall area facing the seat. The The transmitter coil can be mounted similarly to the receiver coil described above.

In a particularly preferred embodiment of the toilet seat set according to the invention, the transmitter coil and the receiver coil are arranged in such a way that they are directly opposite each other when the seat is lowered. This improves the energy transfer between the two coils.

If the transmitter coil and the receiver coil are arranged opposite one another, the distance between the coils can advantageously be a maximum of 20 mm, in particular a maximum of 15 mm, in particular a maximum of 10 mm. With such a small distance between the coils, the energy transfer is improved and disruptive influencing factors have a significantly reduced influence on the energy transfer.

This minimal installation space can be implemented particularly easily if the transmitter coil and the receiver coil are each designed as spiral-shaped flat coils, the turns of which are each spiral-shaped in one plane, the winding axis running perpendicular to the winding plane of the respective coil (receiver coil, transmitter coil). It is particularly preferred if the winding axes are arranged coaxially to one another, so that the flat coils run parallel to one another.

In addition, it is preferred if the seat has a maximum thickness of 20 mm, in particular a maximum of 15 mm. In this way, a special aesthetic of the seat is achieved, which is generally required by the demanding market for seats and toilet seat sets. Such a low overall height can be realized particularly easily when using the carrier mentioned at the beginning to stabilize the seat structure.

In a preferred embodiment of the invention, the technology box is arranged between two clamps of the seat and the cover. Through this arrangement the pivotable connection according to the invention between the seat and the cover and the technology box is also made possible.

The technology box preferably has receptacles for the seat and the cover, on which the seat and the cover are pivotably connected to the technology box. Two swivel axis sections are provided for the seat and two swivel axis sections for the cover, so that a separate swivel axis is formed for the seat and for the cover.

A system according to the invention has a toilet seat set as described above and at least one additional control and display element that can be wirelessly connected to the toilet seat set. This wireless connection is, for example, a Bluetooth or WLAN connection, although other connections such as radio connections are also conceivable. With a preferred WLAN connection, the toilet seat set and / or the control and display element can be integrated into a network so that Internet of Things (loT) communication can take place.

In the concept according to the invention with two flat coils (receiver coil, transmitter coil) arranged at a short distance from one another, it is not necessary to integrate an energy storage device, for example a battery or a capacitor arrangement, into the seat. This was necessary in the known solutions described at the beginning.

The applicant reserves the right to address the above aspects, advantageous developments of the invention and, if necessary, independent claims.

An embodiment of a toilet seat set according to the invention and a system according to the invention is shown in the figures.

FIG. 8 is a block diagram of a system according to the invention.

In Figure 1, a toilet seat set 1 according to the invention is shown. Such a toilet seat set 1 is designed with a toilet seat 2 and a toilet lid 4 (hereinafter referred to as the seat and lid), as well as a technology box 6. The technology box 6 is arranged between two clamps 16 of the seat 2 and between two clamps 18 of the cover 4. In the three-dimensional, perspective view according to FIG. 1, it can be seen that the technology box 6 forms a first pivot axis via which the cover 4 can be pivoted. A further separate pivot axis for the seat 2 is formed on the technology box 6. The toilet seat set 1 thus has two separate pivot axes, one for the seat 2 and one for the cover 4.

The toilet seat set 1 is fastened to the ceramic (not shown) via the technology box 6, which is fixed to the ceramic by means of suitable fasteners. In FIG. 1, the reference numeral 7 designates a sensor which is integrated in the cover 4 in this exemplary embodiment. This sensor 7 can be, for example, a receipt sensor which, when the cover 4 is opened, emits a corresponding signal to the central controller (see FIG. 8) of the seat set 1. The sensor can also be designed as a motion sensor or a distance sensor. Lighting can also be provided at this position or on the seat or on the technology box.

FIG. 2 shows the toilet seat set 1 according to the invention according to FIG. 1 in a view from below, that is, from a ceramic (not shown). In the technology box 6, a transmitter coil 8 is provided in an area arranged below the seat 2. In addition to the transmitter coil 8, the technology box has two receiving sleeves 10. Fastening means, not shown here, extend through these receiving sleeves 10 and are preferably designed as pins, which in turn are fastened to the ceramic, also not shown. The technology box 6 is held firmly and preferably releasably on the ceramic via the fastening means. In the area of the clamps 16, 18, the technology box has pins 12, 14 which extend laterally out of the technology box 6. These pins 12, 14 are designed as hollow pins in the present figure and are designed in one piece with the technology box 6. Of course, other variants of the pins 12, 14 are conceivable, so that they are made of solid material and / or are used as additional components that are independent of the technology box 6 in recesses in the technology box 6. The pegs 12 closer to the seat dip into the block 16 of the seat 2, while the pegs 14 facing away from the seat dip into the block 18 of the cover 4.

The pivot axes formed by the pins 12 and 14, in the exemplary embodiment according to FIGS. 1 and 2, run parallel to one another. In principle, however, it is also possible to mount the seat 2 and the cover 4 on a common coaxial pivot axis. The pivot axes can also be arranged one above the other with a view of the ceramic.

In the illustration according to FIG. 2, a bottom that closes the technology box 6 downwards towards the ceramic is not shown, so that the interior of the technology box 6 is practically visible. In the illustration according to FIG. 2, this is shown without the components included therein. This will be discussed in more detail below.

Figure 3 shows a detailed view of the technology box. For the sake of clarity, in this, as in FIG. 2, reference symbols are only provided on one side, since the outer contours of the technology box 6 are constructed approximately mirror-symmetrically. On the side shown here on the right, the pins 12 forming an axis of rotation for the seat 2 and the pins 14 for the cover 4 can be clearly seen. As already discussed above, a large number of variants are conceivable which can dip into the clamps 16 of the seat 2 and the clamps 18 of the cover 4 so that they are pivotably mounted on them. These pins 12, 14 can preferably be designed with dampers, so that the pivoting movement of the seat 2 and the cover 4 is muted. In the case of a motorized swivel drive, the pins 12, 14 are designed as drive shafts which are in operative engagement with the clamps 16, 18.

As mentioned above, essential elements for the function of the toilet seat set 1 according to the invention, such as an energy transmission device, a control unit for controlling the various consumers, possibly a deodorizer and / or a swivel drive for the seat 2 and the cover, are placed in this technology box 4 added. Such components can be seen in the block diagram according to FIG. 8, for example.

FIG. 4 shows a seat 2 of the above-described toilet seat set with a carrier 20 arranged in this seat 2. In this representation of the seat, the clamps 3 and the clamps 16 formed thereon of the seat 2 with recesses integrated therein for the pins 12, not shown Technology box 6 easy to see. It can also be seen from the illustration in FIG. 4 that the carrier 20 is designed such that its shape is adapted to the geometry of the seat 2 in such a way that it is preferably completely covered by the seat 2. It is particularly preferred if the carrier 20 is pressed with the base material of the seat 2 or, in the case of a cheaper design, is encased by injection molding. As can be seen in the illustration according to FIG. 4, the carrier 2 extends into the area of the clamp 16 and is designed in accordance with the clamp contour. If this carrier 2 is manufactured from a comparatively dimensionally stable material, for example fiber-reinforced plastic or metal, the cavity can be designed during compression / injection molding in such a way that only a type of outer skin is formed that completely surrounds the carrier 2 so that it is covered with a can be designed with a minimum overall height.

The illustration according to FIG. 5 shows an individual illustration of the carrier 20 in a view from below, that is to say seen from a ceramic (not shown). A receiver coil 22 is arranged on the carrier 20. This is either held on the carrier 20, connected to it, or integrated into it. Furthermore, this carrier 20 can hold further electrical loads, such as sensors, a seat heater or the like. As mentioned at the beginning, such electrical consumers for example a receipt sensor, vital parameter sensors, or a distance sensor. In principle, however, it is also possible to integrate lighting means, for example LEDs or the like, into the carrier 20 or the seat 2. In addition, the carrier 20 can fulfill a stiffening function in the seat 2, which is preferably made of SMC material.

In FIG. 5, receptacles are shown with the reference numeral 19 which extend in the direction of the ceramic and which are used, for example, for a form-fitting connection with the base material of the seat 2, which is connected to the carrier 20 during the pressing / overmolding. The recordings can also be designed in such a way that buffers on the support side are fixed to them.

In the illustration according to FIG. 5 on the right, block tabs 21 are shown, which are designed according to the contour of the block 16 described above and give them enormous rigidity.

In the exemplary embodiment according to FIG. 5, the receiver coil 22 is received in a coil holder 23, which is also formed on the carrier 20. As can be clearly seen in FIG. 5, the coil is designed as a flat coil with a spiral winding 26. The assigned transmitter coil 8 has a corresponding structure.

The reference numeral 32 denotes further holders formed on the carrier 20, via which further functional elements, for example one of the sensors described above, can be fixed. As explained in more detail below, the carrier 20 can also be provided with the seat heater, which is then applied to the upper side of the carrier 20 facing away from the viewer in FIG. This seat heater can be designed as a foil heater, for example.

FIG. 6 shows a three-dimensional sectional view of the closed toilet seat set 1 according to the invention. The seat 2 with the integrated support 20 below the cover 4 can be clearly seen. In the part of the illustration on the right here, part of the technology box 6 is visible. On its left-hand side here, this has a housing section 24 sloping downwards towards the ceramic. This is built up in stages, see above that it extends below the seat 2. The closed cover 4 covers a first stepped section 25 which, when the cover 4 is open, separates only a small gap from a rear end of the seat 2. A gap between the technology box 6 and the lid 4 is also kept to a minimum when the lid 4 is closed, so that an aesthetic appearance of the toilet seat set is guaranteed and the ingress of dirt or the like is prevented. A second stepped section 27 of the inclined housing section 24 extends below the seat 2. The distance between the seat 2 and the second stepped section 27 is also kept small.

The profile of the carrier 20 can also be clearly seen in FIG. As mentioned above, this follows the seat contour, for example the profile of the carrier in the front area of the seat 2 (left in Figure 6) is approximately U-shaped with side cheeks 36 which extend in sections into side cheeks 38 of the seat 2 . In a corresponding manner, the area of the carrier 20 on the technology box side is approximately L-shaped, with a single side cheek 36 extending into the area of the side cheek 38.

In the schematic sectional view of the toilet seat set 1 in the area of an energy transmission device according to FIG. 7a, the technology box 6 and a part of the seat 2 facing the technology box are shown. From this illustration it can be seen that when the toilet seat set 1 is closed, the transmitter coil 8 and the receiver coil 22 are directly opposite one another and with their windings 26, 28 are aligned largely parallel to one another. In the greatly simplified illustration according to FIG. 7 a, it can be seen quite clearly that the receiver coil 22 is held by the carrier 20 integrated in the seat 2. In the illustrated embodiment, the receiver coil 22 and the transmitter coil 8 integrated in the inclined housing section 24 are designed as ring-shaped or spiral-shaped flat coils, the winding axis of which is indicated in FIG. That is, the coil windings 26 are arranged flat so that both coils are very flat and thus require little installation space. This is a considerable difference from the solutions described above, in which the coils are wound in a helical manner. In the detailed view according to FIG. 7b, the seat 2, the technology box 6 with the second stepped section 27 of the inclined housing section 24 and the transmitter coil 8 and receiver coil 22 built into it are also shown. The distance A between the flat windings 26 of the receiver coil 22 and the flat windings 28 of the transmitter coil 8 is between 5mm and 20mm, preferably 5mm to 15mm and particularly preferably between 5mm and 10mm. The efficiency of inductive coupling coils for use in toilet seat sets is greatest in this distance range.

A block diagram of the system according to the invention is shown schematically in FIG. 8 as a circuit diagram or flow chart. The main components of the system, that is to say the toilet seat set 1 with its seat 2 and technical box 6 components shown here as subgroups, and an operating and display element 30 are shown in their operative connection. The operating and display element 30 serves, on the one hand, to control the functions of the toilet seat set 1 and, on the other hand, to display parameters and / or status messages from electrical consumers determined by means of the toilet seat set 1. This operating and display element 30 can be, for example, a smartphone, a tablet, a handheld or a similar portable system that is equipped with an app for communication with the toilet seat set 1.

This operating and display element 30 is connected to the toilet seat set via a wireless connection. This is implemented as a radio, Bluetooth, or preferably as a WLAN connection. A WLAN connection has the advantage that it can be integrated into / via an IoT network via a network protocol. The operating and display element can thus serve as a control element for the toilet seat set. In addition, with an IoT connection, a further, external control of the toilet seat set 1 is also possible, since at least this, or also the control and display element, can be implemented in a network with an IP address and thus also remotely can be controlled via a remote app or similar. Complete integration into a smart home is guaranteed. At least two sub-functional areas are provided within the toilet seat set 1. On the one hand in the technology box 6, the functions are described in the right box, and on the other hand in the seat 2, the functions of which are described in the left box.

The technology box 6 is connected to the operating and display element 30 via the wireless connection set out above. The control of the technology box 6 takes place via a microcontroller, which can also communicate with the operating and display element 30. For example, a hot conductor (Negative Temperature Coefficient Thermistor, NTC) is connected to the microcontroller via a Serial Peripheral Interface (SPI), which receives the temperature in the technology box 6 as an input and transmits it to the operating and display element 30.

Furthermore, the technology box 6 or the seat 2 / cover 4 has a distance sensor and / or a liquidity sensor, the distance sensor recognizing an approaching user and the liquidity sensor detecting the ambient light. The information from these two sensors is used to transmit to one or more LEDs contained in the technology box, on the one hand, a control signal (distance sensor) to switch on the LEDs and, on the other hand, to adapt their luminosity to the ambient light (brightness sensor). The technology box 6 can also contain a weather station which, for example, calls up current weather data online in order to visualize it for the user in real time or as a forecast on the operating and display element 30.

A so-called deodorizer is also contained in the technology box 6, which, for example, depending on the receipt sensor 7, which in turn can determine the duration of the user's stay, a predefined fragrance or a mixture, for example from a mixture of different fragrances from a non shown reservoir, in the ceramic, or otherwise in the vicinity of the toilet or the toilet seat set 1, sprayed, vaporized, or otherwise emits. Furthermore, at least one swivel drive can be contained in the technology box 6 or be controlled by it. This swivel drive can cover 4 and / or seat 2 automatically open and / or close when a person approaches, or when controlled via the operating and display element 30.

In addition, the technology box 6 according to this exemplary embodiment has what is known as a wireless power transmitter, which has an induction coil on the one hand and control electronics for this induction coil on the other. The induction coil is referred to as transmitter coil 8 in the present application.

All electrical components contained in the technology box 6 can be wired via the aforementioned SPIs, via Inter-Integrated Circuit (I2C) or via other BUS systems, or have a wireless connection. A power supply unit, for example, is connected to the wireless power transmitter via a cable.

The seat 2 can also contain a microcontroller which is connected to the microcontroller of the technology box 6 via Bluetooth, for example. As explained, the seat 2 can have a seat heater which is controlled as a function of an NTC installed in the seat 2 or of the receipt sensor of the technology box and / or of an input by the user on the operating and display element 30. In addition, the seat 2 can have sensors or other elements that recognize and / or determine the vitality parameters of the user and forward them to the operating and display element 30 in real time.

Thanks to the IoT connection, this data can be stored in a cloud, for example, so that the user can call up the data at any time in order to identify any deviations that may occur. In addition, a so-called wireless power receiver is integrated in the seat 2. This consists of an induction coil and electronics assigned to the induction coil. The induction coil is referred to in the present application as the receiver coil 22 and is arranged in the seat 2 in such a way that it is opposite the transmitter coil 8 of the technology box 6 when the seat 2 rests on the ceramic. All of the electrical components contained in the seat 2 can also be connected by wire via the aforementioned SPIs, via Inter-Integrated Circuit (I2C) or via other BUS systems, or have a wireless connection. A power supply unit is connected to the wireless power transmitter via a cable.

Disclosed is a toilet seat set with a seat, a lid and a technology box. An energy transfer device for wireless energy transfer is integrated in the toilet seat set in such a way that the energy transfer takes place between the technology box and the seat.
