Description

TECHNICAL AREA

[0001] The present invention relates to a bidet function device for toilet seats, comprising a reservoir for the flushing medium, a pump unit for dispensing the flushing medium from the reservoir, a line for the flushing medium connected to or connectable to the reservoir, and a nozzle connected to or connectable to the line. The present invention further relates to a toilet seat or a toilet equipped therewith, in particular with the bidet function device configured as a mobile retrofit unit. Finally, the present invention also relates to the use of such a bidet function device for retrofitting or upgrading a toilet seat or for providing a portable mobile assembly with such a bidet function device. Finally, the present invention also relates to a computer program for preferably wirelessly controlling the operation of such a bidet function device.In particular, the invention relates to a bidet function frame and a toilet seat or a WC toilet according to the preamble of the respective independent or dependent claim. BACKGROUND OF THE INVENTION

[0002] The need for hygiene varies considerably from person to person. The manner of daily personal hygiene can also be influenced by cultural differences. For example, in upscale hotels and service establishments, spacious bathrooms may include bidets or bidet facilities alongside toilets; however, this redundancy in sanitary facilities typically requires a relatively large amount of space and, not least for cost reasons, is rather uncommon in private homes.

[0003] To avoid the space required for two toilet bowls installed side by side, attempts have already been made to equip toilet seats with cleaning functions by integrating the device directly into the seat itself. However, experience has shown that these measures are associated with a comparatively high level of (cost) effort.

[0004] Based on this, there is interest in means for realizing a bidet function in the most cost-effective and technically streamlined way possible.

[0005] An example is publication DE 91 00 268 U1, which describes a toilet seat-bidet combination in which the application of the bidet function is initiated manually via a lever and a valve operated by the user.

[0006] Based on the current state of the art, there is a need for improved devices with a bidet function that can be implemented in conjunction with a toilet lid or toilet seat. Furthermore, there is interest, particularly with regard to cost and ergonomics, in especially simple and hygienic designs. SUMMARY OF THE INVENTION

[0007] The objective is to provide a device with a bidet function that can be advantageously implemented in conjunction with a toilet seat, enabling the bidet function to be provided in a simple, cost-effective, ergonomic, and hygienic manner on a conventional toilet. Furthermore, the objective is to design such a device in such a way that the bidet function can be provided particularly advantageously together with the toilet seat and can optionally also be used elsewhere, e.g., when traveling.

[0008] This problem is solved by a bidet function device according to claim 1, by a toilet seat or a WC toilet according to the corresponding dependent device claim, by uses according to the respective dependent use claim, and by a computer program product for controlling the operation of a bidet function device. Advantageous embodiments of the invention are explained in the respective dependent claims. The features of the exemplary embodiments described below can be combined with one another unless explicitly stated otherwise.

[0009] A bidet function frame for toilet seats is provided, comprising a reservoir for flushing medium, a pump unit for expelling the flushing medium from the reservoir, a line for the flushing medium connected / connectable to the reservoir, and a nozzle connected / connectable to the line;

[0010] According to the invention, it is proposed that the reservoir and the pump unit be portable and mobile (i.e., not fixed to a specific location), with the nozzle designed for temporary or permanent retrofitting / attachment to the underside of the toilet seat in such a way that the bidet function can be applied to an individual (or a user) at least approximately in the individual's sitting / viewing direction, in particular by actuation / motorization upon request by the individual. This facilitates a suitably versatile design, especially in a mobile assembly configuration, where contactless or at least wireless operation can be easily implemented.In particular, the bidet function can therefore be provided in a simple and cost-effective manner in older existing properties, especially without the need for an additional or separate water tank or water connection to the on-site sanitary facilities.

[0011] A bidet function kit or retrofit device is understood here to mean, in particular, a device for equipping or retrofitting an object, device, or product with a bidet function, whether in the context of toilet seat or WC product manufacturing, whether subsequently by the end user, whether while traveling or in other mobile, location-independent living situations, and especially largely independent of any available sanitary facilities. The bidet function kit is advantageously provided as a (assembled) unit with components that can be disassembled or coupled from one another; however, it can also be provided as a permanently mounted or pre-assembled system, with a coupling function only at the interface between the nozzle (or housing) and the toilet seat.

[0012] Personalized terms, unless explicitly formulated in the neuter form, may refer to all genders within the context of this disclosure. Any foreign language expressions or abbreviations used herein are industry-standard technical terms and are familiar to those skilled in the art in the respective language.

[0013] The nozzle is advantageously a round jet nozzle; optionally, an attachment can be provided on the nozzle head, e.g. rotatable / screwable, by means of which the radiation cross-section can be predefined, e.g. changed from a round jet to a more fan-like, flat steel cross-section.

[0014] Advantageously, the nozzle itself is mounted on a pivot, particularly a ball joint. Advantageously, the nozzle protrudes slightly in the axial direction relative to the housing, allowing for manual (haptic) adjustment of the nozzle's orientation.

[0015] It is understood that the bidet function unit is advantageously portable, meaning it can be supplied with its own reservoir and rinsing agent. Optionally, the bidet function unit can also include a heating element for tempering the rinsing medium, particularly in the form of an instantaneous water heater, immediately before application, for example, to set a target temperature of around 30°C or even body temperature, thereby improving hygiene and ergonomics.

[0016] According to one embodiment, the bidet function stand is designed and geometrically configured to be placed on the floor. This also facilitates mobile use, for example, by allowing the user to carry the bidet function stand and install it as needed. For this purpose, the bidet function stand can, for example, have a housing with a relatively large base.

[0017] According to one embodiment, the reservoir and pump unit are housed together in a receiving unit designed to be placed on the ground, particularly with the receiving unit configured as a floor-standing unit, e.g., a floor-standing unit with a cross-section that widens towards the bottom. This also promotes good ergonomics and handling.

[0018] According to one embodiment, the pump unit is powered by an energy storage device within the bidet function assembly, which has at least one actuation button for requesting the motor-generated bidet function via the nozzle at at least one power level. This further simplifies operation and also allows for the implementation of control aspects regarding the application method. Advantageously, the energy storage device provides a power supply for the bidet function over a period of several weeks or months, for example, once daily under standard use, and preferably over three to six months.

[0019] According to one embodiment, the bidet function frame is designed to provide the bidet function at the push of a button or similar user input, without requiring any further manual operation. This simplifies handling even further.

[0020] According to one embodiment, the nozzle is received in a frame or housing, on which at least one tab or similar fastening element is provided for temporary or permanent mounting / attachment to the underside of the toilet seat in a predefined orientation. This also facilitates reversible mounting and the most precise possible alignment.

[0021] According to one embodiment, the nozzle is provided with a double tab or a double / redundant mounting section, by means of which the nozzle can be mounted / fastened at two axially spaced positions. This can further optimize the mounting / fastening and the accuracy of the alignment.

[0022] According to one embodiment, the nozzle can be mounted at variable heights, in particular over a height difference of at least 6 mm relative to the surface or underside of the toilet seat. This also promotes particularly good / high compatibility with various designs (geometries) of toilet seat undersides.

[0023] According to one embodiment, the nozzle is designed for height-adjustable mounting, whereby the height variation can be predefined at at least two different axial positions, in particular by at least two or three superimposed spacers, e.g., each designed as adhesive pads, e.g., with the respective spacer having a thickness of 2 or 3 mm. This also allows the individually desired alignment of the nozzle axis to be achieved in a particularly simple and cost-effective manner.

[0024] Optionally, the nozzle housing can also be mounted about at least one transverse axis relative to the toilet seat, wherein the height-adjustable mounting arrangement includes a height-adjustable mechanism at at least one axial position, e.g., height-adjustable via a screw or a spindle or the like (e.g., counter-bearing in a mounting section of the housing and acting in the vertical direction). This height setting can optionally be specified wirelessly or without contact, e.g., via an app on a terminal device, to control at least one actuator acting on the height position or on the height / alignment adjustment means. For example, the actuator can be controlled wirelessly via a near-field communication interface, e.g., via the Bluetooth communication standard and / or via at least one Low Power Wide Area Network (LPWAN).The actuator can be coupled to the energy storage device via an energy connection or be energy self-sufficient, at least for a period of several weeks or months, i.e., be equipped with its own energy source or energy storage element.

[0025] Alternatively, the application method can be predefined such that the nozzle's orientation during application covers at least one angular range, in particular a predefined elevation angle range and / or a predefined azimuth angle range. At least one actuator can also be provided for setting the (instantaneous) azimuth angle, and the nozzle can be mounted on a vertical axis.

[0026] According to one embodiment, the nozzle can be mounted on the underside of the toilet seat in a predefined orientation by means of a form-fit and / or force-fit and / or a material bond, optionally by means of fastening devices comprising, for example, at least one adhesive pad and / or at least one suction cup or an equivalent means in the form of a cup-shaped structure made of elastic material. A form-fit / force-fit facilitates frequent reversibility / removability, while a material bond may simplify the method of attachment and allow for at least several removals, optionally based on multiple superimposed adhesive layers. Suction cups have the advantage that mobile, portable, and situation-specific use can be implemented particularly advantageously, independent of fixed sanitary fixtures. In particular, the nozzle can be easily decoupled / detached.The person skilled in the art can specify the most advantageous type of assembly, depending on the application, based on the present disclosure.

[0027] According to one embodiment, the line is a hose, which is preferably reversibly connectable to both the reservoir and the nozzle, and in particular, can be attached using a flexible material. This allows for installation or application by connecting the hose to permanently installed nozzles. Optionally, a power supply line can also be provided on the hose.

[0028] According to one embodiment, the nozzle's application direction is adjustable, particularly by means of a ball joint bearing for the nozzle. This also facilitates a high degree of variability with regard to user preferences.

[0029] According to one embodiment, the nozzle's application direction in an xz-plane is adjustable within a predefined / predefinable (elevation) angle range, particularly within a range of 30° around the horizontal plane. This also facilitates (body) size adjustments.

[0030] According to one embodiment, the nozzle's application direction in an xy-plane is adjustable within a predefined / predefinable (azimuth) angle range, particularly within a range of 30° around the seating / viewing direction. This also promotes the largest possible application area.

[0031] According to one embodiment, the nozzle, in its intended position, is aligned at a predefined angle relative to the horizontal plane, in particular at an application angle in the range of 10–20° between the nozzle axis and the horizontal plane. This also promotes high compatibility with regard to height differences in the mounting position. The slightly upward-directed spray pattern also facilitates good target acquisition, as independent as possible from individual body size and / or shape.

[0032] According to one embodiment, the nozzle, including its bezel or housing, when arranged / oriented as intended, particularly at least approximately horizontally, is no more than a few millimeters high. This also promotes high compatibility with a wide variety of standard toilet seats.

[0033] According to one embodiment, the bidet function assembly is designed to provide at least two different performance levels of a motor-driven bidet function. This also allows for user-specific customization.

[0034] According to one embodiment, the nozzle housing or enclosure essentially consists of a conduit section that receives the nozzle and a flat, laterally extending mounting section, in particular as an integral one-piece assembly. The conduit is advantageously connectable at a free end of the conduit section, especially by means of a flexible push-fit / coupling mechanism. This also facilitates a simple, robust, and cost-effective design, making it particularly suitable for additive manufacturing processes. The housing / enclosure can further include a receptacle or cavity for a (ball) joint for the nozzle.

[0035] The aforementioned problem is also solved by a toilet seat with a bidet function attachment according to the present disclosure. This allows the aforementioned advantages to be realized, particularly with regard to the functional integration of at least one coupling part of a coupling for the bidet function attachment or its nozzle or its nozzle housing.

[0036] According to one embodiment, a housing or enclosure for the nozzle is integrally integrated into the underside of the toilet seat, particularly in combination with a positive-locking / force-fit coupling for the nozzle. This facilitates even easier handling, allowing for the optional use of a portable bidet attachment carried by the user, thus eliminating the need to attach a coupling component to the toilet seat or initiate an assembly process. Instead, the toilet seat can be folded up and the nozzle of the user-specific bidet attachment connected.

[0037] According to one embodiment, a housing or enclosure for the nozzle is arranged on the underside of the toilet seat, with the housing or enclosure being no more than a few millimeters high. This also promotes high compatibility with many common toilet seat designs, especially when the nozzle axis is adjustable.

[0038] According to one embodiment, the nozzle with its surround or housing remains invisible to a person using the toilet seat as intended when it is in its normal position; that is, it lies outside the field of vision, and in particular is completely concealed by the toilet seat itself. This also facilitates cleaning of the toilet seat itself, especially its upper surface.

[0039] According to one embodiment, the toilet seat is made of plastic, the frame or housing is also made of plastic, and the nozzle is made of plastic or metal. This design also facilitates advantageous manufacturing processes such as additive manufacturing or injection molding.

[0040] According to one embodiment, the toilet seat is a molded part produced by injection molding or a plastic part produced by at least one additive manufacturing process. This allows, among other things, for a particularly cost-effective provision or a particularly flexible / variable creation of a toilet seat that is advantageously compatible with the nozzle of the bidet function assembly.

[0041] The aforementioned problem is also solved by a WC toilet with a toilet seat equipped with a bidet function frame according to the present disclosure.

[0042] According to one embodiment, the nozzle of the bidet function unit is reversibly connectable, in particular by positive and / or force-fit connection. This also facilitates particularly easy mobile use in different locations and situations. Furthermore, some of the components of the bidet function unit, especially the reservoir and pump, can be provided and used together as a set with multiple nozzles for different users, thus further increasing customizability.

[0043] According to one embodiment, the detergent supply for the bidet function unit is independent of the water supply system of the toilet. This also allows for a considerable reduction in installation effort.

[0044] The aforementioned problem is also solved by using a bidet function mounting device comprising a reservoir for the flushing medium, a motor-activated pump unit, a line for the flushing medium, and a nozzle designed for mounting / fastening in a predefinable height position and orientation on the underside of a toilet seat, in particular a bidet function mounting device according to the present disclosure, for equipping a WC toilet with an actuator-driven / motor-generated bidet function that can be called up on demand by a user. This allows the aforementioned advantages to be realized, especially with regard to a particularly practical and streamlined provision of the bidet function in sanitary facilities without having to modify the latter accordingly.

[0045] The aforementioned problem is also solved by using a portable, mobile bidet function device comprising a reservoir for the flushing medium, a motor-activated pump unit, a line for the flushing medium, and a nozzle designed for mounting / attachment in a predefinable height position variable by at least 6 mm and in a predefinable orientation on the underside of a toilet seat, in particular a bidet function device according to the present disclosure, for retrofitting an already installed toilet or an already usable toilet seat with an actuator-driven / motor-generated bidet function that can be called up on demand by a user. This allows the aforementioned advantages to be realized, especially with regard to particularly good mobility and flexible use by the respective user, e.g., when traveling or abroad or in other cultural contexts.

[0046] The aforementioned problem is also solved by using a bidet function assembly comprising a reservoir for the flushing medium, a motorized pump unit that can be activated contactlessly or at least wirelessly, a line for the flushing medium, and a nozzle designed for mounting / fastening in a predefinable height position variable by at least 6 mm and in a predefinable orientation on the underside of a toilet seat, in particular a bidet function assembly according to the present disclosure, for providing a portable, mobile, or mobile-usable assembly for location-independent application of a bidet function, especially wirelessly via a user interface using a mobile device. This allows the aforementioned advantages to be realized, particularly with regard to excellent ergonomics and hygiene.

[0047] The aforementioned problem is also solved by a computer program product comprising commands which, when the computer program product is executed on a computer, cause the computer to execute steps for controlling and optionally also regulating a method for the fully automatic provision of a bidet function by a bidet function setup device according to the present disclosure on the computer, for providing a bidet function that can be retrieved on request by a user via a mobile device, in particular a computer program product configured for requesting the bidet function via a mobile device with at least one parameter predefinable via a user interface from the following group: nozzle orientation angle, application strength (pressure, power level, intensity), application duration, application pattern, optionally also a rinsing agent temperature.Based on the aforementioned advantages, this also allows for a beneficially high degree of individualization with comparatively little effort.

[0048] An application pattern can be understood as, for example, a specific intensity profile and / or a specific nozzle axis orientation profile. This could involve, for instance, an initially relatively low intensity in at least one predefined orientation, with increasing intensity in this at least one orientation and / or in at least one further predefined orientation. The increase in intensity may also occur only upon confirmation by the user, particularly via a device. In this way, manual contact with the nozzle is not required to customize the bidet function, thus significantly improving hygiene, well-being, and ergonomics.

[0049] Summary: A bidet function typically requires a relatively high level of effort in sanitary fittings and / or a relatively high degree of user interaction. In contrast, the present invention relates to a bidet function mounting device for toilet seats, comprising a reservoir for the flushing medium, a pump unit for expelling the flushing medium from the reservoir, a line for the flushing medium connected to / connectable to the reservoir, and a nozzle connected to / connectable to the line; wherein the reservoir and the pump unit are portable and mobile (i.e., not fixed in one location), and wherein the nozzle is designed for temporary or permanent retrofitting / attachment to the underside of the toilet seat in such a way that the bidet function can be applied to an individual at least approximately in the individual's sitting / viewing direction, in particular by actuation / motorization upon request by the individual.The present invention further relates to a toilet seat or toilet equipped therewith, as well as the use of such a bidet function device for retrofitting or upgrading a toilet seat or for providing a portable mobile assembly with such a bidet function device, and a computer program product for preferably wireless control of the operation of such a bidet function device. The associated advantages are described in detail below with regard to the individual features of the invention. BRIEF DESCRIPTION OF THE FIGURES

[0050] The invention is described in more detail in the following drawings, whereby reference numerals not explicitly described in a particular drawing are made to the other drawings. They show, in schematic representation: Fig. 1 in a side view from the front a bidet function frame device according to an embodiment, in the intended arrangement on a toilet seat which is already mounted on a WC toilet; Fig. 2 in a lateral side view a mobile bidet function device according to exemplary embodiments or an assembly formed from components of the bidet function device, wherein the nozzle of the bidet function device is shown in its intended orientation; Fig. 3 in a roughly schematic view a user interface displayed on an end device for controlling a bidet function frame device according to exemplary embodiments; DETAILED DESCRIPTION OF THE FIGURES

[0051] The invention will first be explained with general reference to all reference numerals and figures. Specific features or individual aspects, or aspects of the present invention that are clearly visible / representable in the respective figure, will be addressed individually in connection with that figure.

[0052] A bidet function device 10 for toilet seats 20 is provided, comprising a reservoir 11 for flushing medium 12 (e.g., water or similar flushing fluid with added cleaning agent), a pump unit 13 for expelling the flushing medium from the reservoir, a line 17 for the flushing medium connected to / connectable to the reservoir, and a nozzle 18 connected to / connectable to the line; wherein the reservoir and the pump unit are portable and mobile, and the nozzle is designed for temporary or permanent retrofitting / attachment to the underside of the toilet seat 20 in such a way that the bidet function can be applied to an individual or user 1 at least approximately in the individual's sitting / viewing direction, in particular by actuation / motorization upon request by the individual. At least the reservoir and pump unit can be housed in a receiving housing 10.The receiving housing 10.1 may be arranged / received and placed on the floor or surface 3 with a support or base 16, in particular with its underside. Furthermore, the receiving housing 10.1 may enclose an energy storage device 14. The receiving housing 10.1 may also be provided with at least one actuation button 15 (e.g., haptic and / or based on proximity sensor technology) by means of which the application method can be controlled. The line 17 for the flushing medium extends from the receiving housing 10.1 to the nozzle 18, which may be coupled or mounted on the underside 21 of the toilet seat 20, or temporarily or permanently (more or less irreversibly) attached. The nozzle itself may be housed in a casing or enclosure 19, and may also include a (ball) bearing for adjusting the nozzle's orientation.

[0053] It is understood that the pump unit can be connected to or equipped with a control / regulation device, optionally in conjunction with a communication module for wireless data transmission, for controllable interaction with a user. Optionally, the control / regulation device is configured to control / regulate further (optional) components of the device 10, such as a heating device for the flushing medium, particularly in the form of an instantaneous water heater.

[0054] The housing 19 for the nozzle can have a conduit section 19a and a mounting section 19b, either as an integral one-piece design or as a multi-part design. The conduit section 19a can optionally also serve as a passage for the flushing medium, e.g., from a hose coupling to the nozzle itself. Advantageously, at least one tab 19.1 or similar fastening element, preferably projecting laterally, is provided on the mounting section 19b. Optionally, a double tab or a double / redundant fastening element 19.2 is provided, particularly if height and / or orientation adjustability is to be implemented or can be implemented. The fastening / mounting means 19.Three examples of fasteners that can be mentioned are: material-bonded fasteners, form-fit and / or force-fit fasteners; purely by way of example, adhesive pads, screw connections, clip / plug connections or a form-fit receptacle may be mentioned. In line section 19a, a bearing 19.5 for the nozzle may also be provided, in particular adjustable with regard to the orientation of the nozzle, e.g. comprising a ball bearing.

[0055] The components reservoir, pump unit, pipe, nozzle and optionally at least one coupling (for the pipe or for mounting on the toilet seat) form an advantageously mobile, portable assembly 100. This assembly 100 can be easily assembled by end users without prior knowledge or special skills, and its individual components can also be used separately.

[0056] The toilet seat 20 itself can be equipped with a coupling part or coupling 23 for the nozzle (e.g. a male or female part of a plug coupling, e.g. a bridge with negative receptacle), e.g. in an integral one-piece design for the purpose of particularly good hygiene or easier cleaning or better standard compatibility.

[0057] Therefore, with a suitably equipped WC toilet 30 with bidet function mounting device 10, it is possible to provide the bidet function without having to adapt the WC bowl 31 or the cistern 33 or the water supply of the WC toilet (external or built-in) accordingly.

[0058] Alternatively, the bidet function setup device 10 can be controlled via an end device 40 or an app or a corresponding computer program, in particular via a user interface for specifying at least one parameter from the following group: orientation angle of the nozzle, application strength, application duration, application pattern.

[0059] The following section explains special features of the invention with reference to individual figures or embodiments.

[0060] In Fig. Figure 1 shows the intended arrangement of the nozzle 18 and its housing 19. The coupling part 23 indicated on the underside 21 is designed, for example, as a rib to which the mounting section or the pipe section of the nozzle housing can be coupled (by the user 1), for example, by clipping or plugging it in a positive / force-fit manner. Fig. Figure 1 also indicates the optionally adjustable application direction X18 of the nozzle or the nozzle (longitudinal) axis as well as the optionally adjustable application angle β18 between (current) nozzle axis and vertical plane (xz).

[0061] In Fig. Figure 2 shows a mobile assembly 100 with its essential components; the nozzle is shown in its intended orientation, and the application angle α18 between the nozzle axis and the horizontal plane is indicated. By default, the longitudinal axis X18 can be slightly inclined upwards; therefore, the housing towards the outlet can also have a slight upward bend, indicated here by the dashed line. The nozzle and its housing 19 are shown in their intended orientation (i.e., when it is mounted as intended on the underside of the toilet seat, which is not shown). The indicated fastening means 19.3 can be, for example, adhesive pads or suction cups and can also provide a height adjustment function, by means of which the orientation can be individually adjusted (especially manually). Optional actuators for wireless adjustment of the application direction are not explicitly shown.The bearing 19.5 advantageously includes a ball joint for the nozzle. Because the nozzle tip protrudes slightly forward, the application direction of the nozzle can also be adjusted manually.

[0062] Fig. Figure 2 also illustrates the three spatial directions, namely the sitting / viewing direction (x) of an individual in a position on the toilet seat, orthogonal / perpendicular to this the transverse direction (y), as well as the vertical axis or the vertical direction (z).

[0063] In Fig.Figure 3 shows a mobile terminal 40, via which a computer program can be used to control / regulate the bidet function, in particular via a user interface by which at least one of the following parameters can be set: at least one orientation angle α18, β18 of the nozzle, application strength (intensity parameter, here denoted by "I"), application duration (time parameter, here denoted by "t"), optionally also a user-specific preset application pattern (e.g. intensity as a function of time, and / or angular ranges as a function of time).
