Description

Toilet device and toilet

Technical Field

The present invention relates to a toilet device and a toilet having such a toilet device.

Background

Toilets are commonly used today that can be used by the user in a sitting position. A toilet is a sanitary device for collecting bodily waste, particularly feces and urine. Toilets typically have a bowl or bowl that forms an interior space into which bodily waste is discharged. For this purpose, a person may sit on the toilet seat of the toilet. Body waste can be discharged to a sewer system via a drain pipe, usually by means of a flushing device.

In addition to body waste, a person using a toilet may also release or generate gases from the body waste which can enter the ambient air near the toilet and produce odors. The toilet interior space, i.e., the interior of the bowl, must also be cleaned periodically.

In order to automatically clean the toilet interior of a toilet or a urinal, it is known to use so-called toilet flushers, which hang on the toilet rim in the toilet interior, so that when the flushing device is actuated, water flushes the toilet flushers from all sides and releases a portion of the cleaning agent into the water. This enables a certain degree of cleaning of the internal space of the toilet bowl at the location where the water mixed with the cleaning agent arrives. The cleanser may also contain a fragrance which escapes therefrom and can be released into the ambient air. Both of these situations can always occur automatically upon operation of the flush device.

The disadvantage here is that the cleaning effect is only produced in the interior space of the toilet at the location where the water mixed with the cleaning agent arrives. This can result in uneven cleaning of the surfaces of the interior space of the toilet. Furthermore, only the interior space of the toilet itself can be cleaned in this way.

Another disadvantage is that the odor produced is only masked by the fragrance of the detergent, but remains.

A disadvantage in each case is that the cleaning effect and the fragrance effect depend on the amount of cleaning agent that is dissolved or escapes by the water of the flushing device. Accordingly, as the detergent is reduced, the effect thereof is also reduced.

The general disadvantage is that the cleaning agent is consumed by the use of the toilet and must be renewed or replenished. This can result in cost and effort for the user. These functions are not available, especially in the event of exhaustion of the cleaning agent.

SUMMERY OF THE UTILITY MODEL

It is an object of the present invention to provide a toilet device in order to avoid or at least reduce bad smell when using the toilet and/or to improve and/or simplify cleaning, in particular disinfection, of the toilet. This needs to be implemented in a manner that is as simple, stable, economical, compact and/or inexpensive as possible. At least an alternative to the corresponding known solutions has to be provided.

Accordingly, the present invention relates to a toilet device having: at least one air guide device designed to guide an air flow from a toilet interior space of a toilet into the toilet device and/or from the toilet device into the toilet interior space of the toilet; at least one blower designed to generate the respective air flow; and at least one ionizer, preferably at least one ozone generator, designed to generate ionized air, preferably ozone, and release it into the respective air flow.

The air guide means may be realized by a hose, a channel or the like and is arranged with an open end towards the inner space of the toilet, so that an air exchange between the air guide means and the inner space of the toilet is possible. The blower can be embodied, for example, as a ventilator or the like and in any case serves for conveying air. The ionizer may be designed as an at least partially ionized air, such as ambient air. This can be achieved by means of high pressure. The ionized air or radicals generated by the ionized air may cause chemical degradation processes that may be used to deodorize and/or disinfect. The use of an ozone generator as the ionizer may be one solution for achieving the above-mentioned ionization of air.

In other words, the present invention can provide a device that can be applied to a toilet. The toilet device may be an integrated component of the toilet or a separate device which may be arranged on the toilet in a non-destructive removable manner. In any case, the toilet device may also be a system consisting of several separate components which functionally interact as a toilet device and which may be spatially separated. The individual components of such a toilet device may be partially integrated into the toilet, partially separated from the toilet, or all of them fully integrated or separate.

In any case, the toilet device of the present invention may be designed to transmit an air flow from the toilet interior space to the toilet device, thereby drawing odor from the toilet interior space into the toilet device. The odour of the inhaled air is then eliminated or at least reduced inside the toilet device by ionizing the inhaled air and/or mixing it with the ionized air. The remaining air, with reduced or completely eliminated odor, can escape from the toilet device and enter the surrounding environment. This eliminates or at least reduces the potential for an environmental odor that may be generated during use of the toilet.

In any case, the toilet device of the present invention is alternatively or additionally designed to deliver an air flow into the toilet interior space. Inside the toilet device, air that can enter the toilet device from the outside may be ionized in advance and then blown into the toilet internal space by the blower. In this case, the ionized air can reach the toilet interior space or its surface and be disinfected. This makes it possible to automatically clean the interior space of the toilet as simply and/or as completely as possible.

The toilet device of the present invention may be designed to perform only one of the two functions described above. Alternatively, the toilet device of the present invention may be designed to provide both of the above functions for use automatically and/or as desired by the user. In this case, the functions can be carried out separately from one another, staggered in time, optionally, or one after the other in combination. In the latter case, it is possible to use, in particular during the use of the toilet by a person and optionally after a certain period of time, firstly a deodorizing or odor-reducing function and then, optionally after a certain period of time, a disinfecting or cleaning function.

In any case, at least the blower and the ionizer may be operated by means of a control unit of the toilet device, which may perform corresponding functions and other functions, such as evaluating sensor information, activating functions according to a time sequence or at a certain moment, etc., as will be explained in detail below. The necessary supply of the toilet device, in particular its electrical and electronic components, can be effected by means of an integrated electrical energy store, as will be explained in more detail below. Alternatively, the toilet device may also be connected to the power supply network, either wired or wirelessly (e.g. inductively).

According to one aspect of the utility model, the toilet device has a device interior which is arranged inside the toilet device and is connected to the air guiding device in a manner guiding an air flow, wherein the ionizer is designed to release the ionized air into the device interior, and wherein the blower is designed to generate a corresponding air flow through the device interior. This enables a volume to be created inside the toilet device in the region of the ionizer and the blower, wherein ionized air can be generated by the ionizer and conveyed by the blower. In particular, a volume can be created inside the toilet device, wherein the odors of the ionized air and the air sucked in from the toilet interior can be mixed, so that a corresponding odor neutralization is caused by the ionized air.

According to another aspect of the utility model, the toilet device has at least one air outlet opening designed to discharge the air flow outwardly from the toilet device, and/or at least one air inlet opening designed to introduce the air flow into the toilet device from the outside. In other words, the toilet device or its device interior is connected with the surroundings in a manner that guides air or air penetration, so that an air flow is generated from the toilet interior through the air guiding device through the toilet device and via the air outlet towards the outside of the toilet device and/or an air flow is generated from the outside of the toilet device through the toilet device and through the air guiding device into the toilet interior. This enables a corresponding air exchange between the toilet device and the surroundings.

According to a further aspect of the utility model, the air outlet and/or the air inlet have at least one, preferably replaceable, filter, preferably an activated carbon filter. This enables a corresponding filtering of the air sucked in from the inner space of the toilet bowl before it is released to the surroundings. An additional odor-reducing effect is thereby achieved, in particular, by means of the activated carbon filter. Additionally or alternatively, if ambient air is drawn into the toilet device from the environment, the ambient air may be filtered accordingly. This enables the dust and similar particles to be filtered from entering the interior of the toilet device, since the components arranged therein, in particular the electronic components, may be contaminated, clogged and/or the cooling effect thereof affected, thereby shortening the service life of these components, in particular the electronic components.

According to another aspect of the utility model, the toilet device has at least one sensor designed to identify the use of the toilet, wherein the toilet device is designed to operate the blower and the ionizer in response to sensorially identified use of the toilet. The toilet device can thus recognize that at least one or both of the above-mentioned two functions are performed automatically one after the other. Thus, the corresponding function does not need to be started by the user. In particular, it is possible to prevent a situation in which the user forgets to activate the corresponding function.

In any case, the sensor may identify (imminent) use of the toilet by: changes in the toilet itself and/or its surroundings are detected by the sensor and are thus recognized by the sensor itself or by the control unit of the toilet device of the utility model. This can be implemented, for example, by means of a motion sensor, a temperature sensor, a pressure sensor, a light barrier, a brightness sensor, etc., which can recognize the presence of a user according to the operating principle, as will be explained in more detail below.

According to a further aspect of the utility model, the sensor is designed as a motion sensor, wherein the motion sensor is designed to be directed at least at an area above the inner space of the toilet. Thus, such a motion sensor can recognize that a person is moving towards the toilet or sitting on the toilet seat and thus infer that the toilet is about to be used. This makes it possible in particular to activate the odor-reducing function in order to immediately suck off the odor and eliminate it or reduce it. The motion sensor may be arranged and aligned on the toilet device such that the corresponding area may be detected by the sensor. In particular, the movement sensor can be arranged and aligned in such a way that its sensor detection area is not covered by the upturned toilet lid.

According to a further aspect of the utility model, at least the air guiding device, the blower and the ionizer on the one hand, and the sensor on the other hand, are designed as separate and spatially separated units from each other. In other words, the toilet device may also be implemented as a system of two separate and spatially separated units, which interact functionally and thus may also be considered together as one device. For this purpose, the two units can be connected to one another by means of data transmission and/or energy transmission, which can be realized in a wired or wireless manner. In any case, this makes it possible to provide the sensor in the form of a motion sensor independently of another unit, so that the design freedom of the sensor can be increased and sensor detection can be facilitated in particular. As a motion sensor, this can prevent, in particular, the sensor detection area of the motion sensor above the toilet bowl from being covered, for example, by a flip-up toilet lid.

According to a further aspect of the utility model, the sensor is designed as a pressure sensor, wherein the pressure sensor is designed to be arranged between a bowl rim of the toilet and a toilet seat of the toilet. In other words, in this way, the load on the toilet seat caused by the weight of the user can be detected by the sensor, so that the use of the toilet can be identified in this way as an alternative or in addition. The pressure sensor may also be considered as a force sensor. Optionally, elastically deformable elements (e.g. rubber elements) may be arranged between the pressure sensor and the bowl rim and/or the toilet seat in order to establish contact between the bowl rim and the pressure sensor and/or between the toilet seat and the pressure sensor in the vertical direction, so that forces or pressures are transmitted efficiently and in particular contactless gaps are avoided. This facilitates or ensures the function of the pressure sensor.

In any case, the identification of the use of the toilet can be carried out later than the motion sensor, which is directed to the surroundings of the toilet or to the area above the toilet seat, since the person must already be seated on the toilet seat when the pressure sensor is loaded. In this way, the use of the toilet can be reliably and directly recognized, since a movement of a person in the area around the toilet or above the interior of the toilet without using the toilet is not mistakenly recognized as using the toilet, as is the case with the movement sensor.

According to another aspect of the utility model, the toilet device is designed to start operating the blower and the ionizer at least one predetermined point in time and/or after at least one predetermined period of time. This makes it possible to use the cleaning function in a time-controlled manner, in particular by means of ionized air. This enables automatic cleaning at predetermined points in time to ensure regular cleaning. Additionally or alternatively, cleaning may also be performed always after use of the toilet, which may be performed automatically after a predetermined period of time after the end of use of the toilet. The end of toilet use may be identified by the sensor in a manner similar to the beginning of toilet use described previously. When using the motion sensor, the end of toilet use can be identified by the person leaving. When a pressure sensor is used, the release of the pressure sensor may indicate that the toilet is finished. In any case, this ensures automatic cleaning after each use of the toilet.

According to another aspect of the utility model, the toilet device is designed to end the operation of the blower and the ionizer after a predetermined period of time. This ensures that the operation of the blower and ionizer can be automatically ended again. The predetermined period of time can be suitably selected to ensure, on the one hand, the respective effect of the respective function and, on the other hand, also to keep the working time and the electric energy consumption of the toilet device at as low a level as possible.

According to a further aspect of the utility model, the toilet device has at least one operating element which is designed such that the operation of the blower and the ionizer can be started or ended by a person operating the operating element. This can provide the user with additional or alternative options for activating and/or deactivating the corresponding function or functions of the toilet device. Such operating elements can be designed as buttons, toggle switches, push buttons, touch sensors, etc.

According to a further aspect of the utility model, the toilet device is designed to be operated by means of an electrical energy storage, which is preferably rechargeable and/or removable. Such an electrical energy store can be embodied as a battery which can be inserted into the toilet device, in particular in a charged state, and which can be removed from the toilet device by the user in a discharged state, in particular by opening a flap or the like. Such an electrical energy store can also be designed to be rechargeable and arranged fixedly in the toilet device in order to be recharged in the toilet device, for example by connecting a charging cable. The rechargeable energy storage may be removed from the toilet device in a manner similar to the batteries previously described and then reinserted after charging.

According to another aspect of the utility model, the toilet device has at least one high-pressure generator designed to generate a high pressure for operating the ionizer. This enables the high pressure required to operate the ioniser to be provided by the toilet apparatus itself.

According to another aspect of the utility model, the toilet device is designed to be removably arranged on the toilet. In other words, as mentioned above, the toilet device is formed in one or more pieces as a device that can be manufactured and installed independently of the toilet itself so that it can then be normally placed on and removed from the toilet as a device or system. Thus, the toilet device is a stand-alone device, not an integral part of the toilet itself. In this way, the toilet device can be retrofitted onto a toilet and/or non-destructively removed for cleaning, servicing, charging an electrical energy storage, and the like.

According to another aspect of the utility model, the toilet device is designed to be arranged in the vicinity of a toilet seat facing away from the toilet interior space. This enables the toilet device to be arranged close to the toilet interior space in order to perform the respective function or functions as desired and preferably as efficiently as possible. In this way, the toilet device can be at least partially hidden from the view of the toilet user, such that the appearance of the toilet device is less or no disturbing to the user.

According to a further aspect of the utility model, the air guiding device is designed to be arranged at least partially between a bowl rim of the toilet and a toilet seat of the toilet. In this way, the air guide can be passed at least partially in a horizontal direction through a gap which is formed generally in a vertical direction between the top side of the bowl rim and the bottom side of the toilet seat, in order to take advantage of this gap which would otherwise exist. Whereby the air guide means is at least partially hidden from view of the toilet user. In addition, the toilet seat can be free of air guiding devices of the toilet device, so that a person can sit on the toilet seat without interference. In this way, the air guide device or its air guide opening can be arranged close to and/or towards the toilet interior.

According to a further aspect of the utility model, the air guide device is designed to project into the toilet interior of the toilet beyond the bowl edge of the toilet. This may be done in both the horizontal and vertical directions, as will be described in more detail below. In any case, the air guide device or its air guide opening can project into the interior space of the toilet in order to perform the respective function or both functions as efficiently as possible.

According to a further aspect of the utility model, the air guide opening of the air guide device is designed to be directed at least substantially horizontally towards the toilet bowl interior space of the toilet bowl. This enables the corresponding air flow to act as horizontally as possible on the entire surface of the interior space of the toilet, so that the odor is removed as completely as possible before it leaves the interior space of the toilet upwards and/or above the rim of the toilet. As such, the air flow flowing into the toilet interior space can reach the toilet interior space as uniformly as possible, and in particular, ionized air from the horizontal direction can sink into the toilet interior space and reach or fill the toilet interior space as uniformly and as completely as possible, thereby improving the cleaning effect.

According to a further aspect of the utility model, the air guide opening of the air guide device is designed to be directed at least substantially vertically towards the toilet bowl interior space of the toilet bowl. This makes it possible to generate as far as possible an air flow for extracting odours from the inner or lower region of the interior space of the toilet bowl, which can facilitate the extraction of odours generated or present there. Likewise, the toilet interior can also be filled from below and up with ionized air in the air flow directed into the toilet interior, which can improve the cleaning effect.

According to a further aspect of the utility model, the toilet device has at least one holder which is designed to hold the toilet device at least in a form-fitting manner on the bowl rim of the toilet. This enables a simple and in particular removable mounting of the toilet device on the rim of the bowl. This can be achieved, for example, by at least one hook-shaped holder which can hook around or catch behind the urinal rim. This makes it possible to hold the toilet device at least form-fittingly, optionally additionally with a corresponding size, press-fit on the bowl rim of the toilet, wherein this additional press-fit holding makes it possible to prevent the toilet device from being displaced or at least difficult to be displaced along the bowl rim. In any case, the holder may be designed as a separate element from the air guide, or it may be formed by the air guide itself, as will be explained in more detail below.

According to a further aspect of the utility model, the holder is formed by the air guiding device. For this purpose, the air guide device can be in particular hook-shaped and in particular guided horizontally in part between the top side of the bowl rim and the bottom side of the toilet seat, so as to point with its air guide opening vertically into the interior space of the bowl, i.e. the toilet interior space. This enables the air guide device to assume the function of a retainer and the function of guiding the respective air flow or both air flows, so that the number of components of the toilet device is kept low. This may reduce the manufacturing costs, installation costs, weight and/or installation space of the toilet device.

According to a further aspect of the utility model, the air guide device is designed to be replaceable. In other words, the air guide device can be non-destructively removed from the remaining components of the toilet device, in particular from the housing of the toilet device, in order to be replaced by the same air guide device. This makes it possible, for example, to replace the air guide device regularly in the event of damage, soiling or for hygienic reasons. In this way, different air guides with different configurations can be used in the toilet device, as described above. So that the toilet device is adapted to the respective toilet by selecting the appropriate air guide.

According to another aspect of the utility model, the toilet device has at least one fragrance generator designed to release fragrance into the respective air flow, preferably into the device interior space. Such an air generator can be a reservoir or storage space, in particular in the form of a liquid, paste or solid corresponding fragrance, in particular in a toilet device, which can be reached in particular by the air flow of a blower. This can carry the aromatic particles of the fragrance along the respective flow direction by the respective air flow to spread the fragrance to the surroundings of the toilet. This can be combined in particular with a odour-reducing function, so that a pleasant aroma of the air surrounding the toilet is additionally provided, so that residual bad smells can be masked.

The utility model also relates to a toilet with at least one toilet device. Such a toilet may have the toilet device of the utility model as a fixed and integrated component or may be provided with the toilet device of the utility model in a non-destructively removable manner. In any event, the above features and advantages of the toilet device of the present invention may be applied to or utilized in a toilet in this manner.

Detailed Description

The above figures are viewed in a cartesian coordinate system. The longitudinal direction X may also be referred to as depth X or length X. The transverse direction Y, which may also be referred to as width Y, extends perpendicular to the longitudinal direction X. The vertical direction Z may also be referred to as height Z and corresponds to the direction of gravity, which is perpendicular to both the longitudinal direction X and the transverse direction Y. The longitudinal direction X and the transverse direction Y together form a horizontal line X, Y, which may also be referred to as a horizontal plane X, Y.

Fig. 1 is a schematic perspective view of a toilet device 1 of the present invention in a first embodiment. Fig. 2 is a view of fig. 1 through a portion of the housing 10. Fig. 3 is a view of fig. 1 as viewed from the opposite side of the opened case 10.

The toilet device 1 according to the utility model has a housing 10 from which an air guide 11 extends straight in a horizontal direction X, Y, which housing can also be referred to as a channel 11. The air guide 11 has a rectangular cross section which is designed to be relatively flat in the vertical direction Z. The air guide means 11 may be replaceable to adapt the toilet device 1 to different types or configurations of toilets 2, or to be able to renew the air guide means 11 if necessary. The air guide 11 faces away from the housing 10 with its end having the air guide opening 11 a. The air guide 11 ends, facing away from the air guide opening 11a, in a device interior 14 inside the housing 10, in which the mechanical, electrical and electronic components of the toilet device 1 are arranged.

The housing 10 is also connected in an air-conducting manner to the surroundings via an air inlet 18 or an air outlet 18, wherein the air inlet/outlet 18 extends flat over the top side and approximately halfway over both side faces of the housing 10. The air inlet/outlet opening 18 has a replaceable filter 17 in the form of an activated carbon filter 17, by means of which air can be exchanged between the surroundings and the device interior 14 in both flow directions.

On the housing 10, a sensor 19a in the form of a movement sensor 19a and an operating element 19b in the form of a push button 19b are also arranged on the side of the housing 10 facing the air guide opening 11a, see fig. 1 and 3.

A blower 13 in the form of a ventilator 13 is also arranged in the device interior 14, which blower, depending on the direction of rotation, can generate an air flow a, which can convey or suck air through the air guide device 11 via the air guide opening 11a into the device interior 14. Due to the corresponding overpressure in the storage interior 14, air can pass from the device interior through the activated carbon filter 17 via the air inlet/outlet opening 18 into the surroundings of the toilet device 1. When the blower 13 rotates in the opposite direction, an air flow B may be generated, which may expel air from the device interior 14 through the air guiding device 11 via the air guiding opening 11 a. Due to the corresponding negative pressure in the storage interior 14, air can be drawn from the environment of the toilet device 1 via the air inlet/outlet opening 18 via the activated carbon filter 17 into the device interior 14. This can generate an air flow a through the toilet device 1 in the suction direction or an air flow B through the toilet device 1 in the discharge direction, depending on the operating mode or depending on the rotation direction of the blower 13.

Also arranged in the device interior 14 is an ionizer 15, which can be supplied with power by a high voltage generator 16. The ionizer 15 can form ionized air or radicals of ionized air from the air located inside the device interior space 14 by means of a high voltage, which can cause a chemical degradation process. The ionized air or the free radicals of the ionized air may be used for deodorization and/or for disinfection, which will be described in more detail below. The ozone generator 15 may be used as the ionizer 15, thereby generating ozone as ionized air or radicals of the ionized air. This may be a possibility for the ionizer 15.

The high voltage generator 16 is arranged on a circuit board (not shown) which also has a control unit 12 which can operate the toilet device 1 or its electrical and electronic components. These components include a blower 13, an ionizer 15, a high voltage generator 16, as well as a sensor 19a and an operating element 19 b. The control unit 12 and the electrical and electronic components are supplied with power by means of a rechargeable electrical energy store 12a in the form of an integrated accumulator 12 a.

Fig. 4 is a schematic perspective view of a second embodiment of the toilet device 1 of the present invention. The toilet device 1 in the second embodiment shown in fig. 4 differs from the toilet device 1 in the first embodiment shown in fig. 1 to 3 in that the air guide 11 is here hook-shaped, forming a retainer 11 b. In this case, the air guide opening 11a is directed downward in the vertical direction Z. On the other hand, a pressure sensor (not shown) is used which is arranged in the area of the air guide 11 in the vertical direction Z below the air guide 11 and pointing downwards, so that the air guide 11 is pressed by the toilet seat 23 against the bowl rim 21, and this can be detected by the pressure sensor as a pressure or force. This may trigger the reaction described hereinbefore with respect to the motion sensor 19a of the toilet device 1 of the first embodiment.

Fig. 5 is a schematic perspective view of a toilet bowl 2 of the present invention having a first embodiment of the toilet device 1 of the present invention shown in fig. 1 to 3.

The toilet 2 is a sanitary device that hangs freely above the floor 4 in the vertical direction Z and is fixedly mounted on the wall 3. The toilet 2 has a bowl rim 20, which may also be referred to as a toilet bowl 20. The toilet bowl 20 has a toilet bowl interior 22 formed therein, which can be flushed with water by a flushing device (not shown). The water of the flushing device may be discharged through the wall 3 to the sewer system through a drain pipe (not shown). The toilet 2 can be used by a user to discharge bodily waste (particularly feces and urine) and can be flushed away with the water of the flushing device. For this purpose, the user can sit on the toilet seat 23 from above in the vertical direction Z, which can be turned up over the bowl rim 21.

The toilet device 1 of the utility model in the first embodiment is arranged between the wall 3 and the toilet seat 23 in normal use, such that the air-guiding device 11 extends between the top side of the bowl rim 21 and the bottom side of the toilet seat 23 and projects horizontally into the toilet interior space 22 beyond the bowl rim 21 and the toilet seat 23 with their air-guiding openings 11 a. The motion sensor 19a is directed to the area above the toilet interior space 22.

If a user of the toilet 2 sits on the toilet seat 23, this condition is detected by the motion sensor 19a sensor and communicated to the control unit 12. Thereby, the control unit 12 recognizes that the user starts using the toilet bowl 2, and causes the toilet apparatus 1 to perform the first function. In this case, the blower 13 is controlled by the control unit 12 in the rotational direction in which the air flow a is generated. This enables the odor that may occur when the user uses the toilet 2 to be sent from the toilet interior space 22 through the air guide device 11 via the air guide opening 11a into the device interior space 14 by the air flow a of the blower 13. Here, the ionized air of the ionizer 15 may be mixed with the air flow a, thereby reducing odor by the ionized air and completely removing it as necessary. Subsequently, the treated air can then pass through the air outlet 18 via the carbon filter 17 to the surroundings, wherein the carbon filter 17 is able to reduce the residual odour and, if necessary, to remove it completely. This keeps the ambient air of the toilet 2 as completely odorless as possible. An aroma generator (not shown), optionally arranged in the device interior space 14, can additionally fill the air released into the surroundings with aroma, so that a pleasant aroma is provided specifically to the ambient air of the toilet 2.

If the motion sensor 19a detects that the user of the toilet 2 is absent, the control unit 12 may accordingly end the operation of the blower 13 and the ionizer 15, since it can be recognized that the use of the toilet 2 by the user has stopped. Alternatively, the control unit 12 may also accordingly wait a certain period of time before the blower 13 and the ionizer 15 are operated, so that the deodorizing function of the toilet device 1 is still used during this period of time, thereby reducing the odor to a greater extent. This is advantageous in order to deodorize as thoroughly as possible even in the presence of strong odours. In any case, the deodorising function can be performed and ended automatically by the toilet device 1.

Therefore, the user can additionally manipulate the operation element 19b as necessary to turn on and off the deodorization function of the toilet device 1, thereby automatically ending after a predetermined time. This enables the user to trigger and terminate the odour reduction function of the toilet device 1.

In addition, the toilet device 1 may also be operated by the control unit with the blower 13 in the opposite rotational direction, thereby generating the air flow B. This enables the cleaning function of the toilet device 1 to be performed in the following way: the ionized air of the ionizer 15 is blown into the toilet internal space 12 through the air guide 11 via the air guide opening 11a by the blower 13. Thereby, the air flow B with ionized air can reach the surface of the toilet inner space 22 and be disinfected.

The deodorizing function of the toilet device 1 can be automatically performed by the control unit 12, for example, each time the deodorizing function of the toilet device 1 is completed. This enables automatic cleaning of the toilet bowl interior space 22 after each use of the toilet bowl 2. Additionally or alternatively, the cleaning function of the toilet device 1 may also be performed automatically by the control unit 12 at regular time intervals and/or repeated time points in order to automatically clean the toilet interior space 22 in a manner independent of the use of the toilet 2 by the user, thereby keeping the toilet 2 in a clean or sterile state. Additionally or alternatively, the user can also initiate the cleaning function of the toilet device 1 by manipulating the operating element 19b as desired. In any case, the duration of operation of the blower 13 and the ionizer 15 for performing the cleaning function of the toilet device 1 may be performed within a predetermined period of time that enables the toilet interior space 22 to be successfully cleaned.

Fig. 6 is a schematic perspective view of a toilet bowl 2 of the present invention having a third embodiment of the toilet device 1 of the present invention. The toilet device 1 in the third embodiment differs from the first embodiment of the toilet device 1 shown in fig. 1 to 3 and 5 in that the toilet device 1 here is formed of two separate units which are arranged spatially separated from one another. In this case, the motion sensor 19a is accommodated in a separate housing (not shown) and arranged on the wall 3 at a distance laterally above the rest of the toilet device 1 in the vertical direction Z and in the transverse direction Y, so that even for a toilet 2 with a toilet lid (not shown) the area above the toilet seat 23 can be optically detected without interference or without being covered as described above. As described above, the toilet apparatus 1 according to the first embodiment can also be applied to the toilet bowl 2 having the toilet lid.

Fig. 7 is a schematic perspective view of a toilet bowl 2 of the present invention having a second embodiment of the toilet device 1 of the present invention shown in fig. 4. In this case, the toilet device 1 is disposed on the bowl rim 21 by hanging the hook-shaped holder 11b on the bowl rim 21 from above in the vertical direction Z. Thereby retaining the toilet device 1 on the bowl rim 21 with a form fit. In this case, the air guide 11 may also extend between the top side of the bowl rim 21 and the bottom side of the toilet seat 23. The air guide opening 11a is directed downwards in the vertical direction Z towards the toilet interior space 22, so that odours can be sucked off there and/or ionized air can be blown into it.
