Description

  The present invention relates to an improvement of a toilet seat apparatus including various functional elements including a local cleaning function.

  Most conventional toilet seat devices have a function for washing a human body part with warm water and a function for warming the toilet seat.

  However, in response to the user's increasing preference for comfort and health, toilet seat devices having a deodorizing function and a room heating function in addition to the above functions have been developed and put into practical use (for example, Patent Document 1). reference).

By the way, the comfort and health orientation of users has become stronger in recent years, and further enhancement of functionality has been demanded for toilet seat devices.
JP-A-4-20622

  The present invention has been invented in view of the above-mentioned conventional problems, and is capable of deodorizing / decomposing adhering odors and dirt using mist generated by atomization, and is efficient so that mist is not sprayed unnecessarily. It is an object of the present invention to provide a toilet seat device that can use mist well and effectively.

  In order to solve the above problems, the present inventor has paid attention to mist that can remove odors in the air, odors attached to the walls, bacteria, viruses, dirt, etc., and means for further enhancing the functionality of the toilet seat device As such, the atomization generator and the means for transporting mist generated by atomization were studied. After intensive research, the present invention has been completed.

  The toilet seat device according to the present invention includes a toilet seat 8 and an atomization generator 10 that generates mist M by atomization, and includes a human detection means 20 that detects the presence of a person in the toilet, Control means 30 for controlling the drive of the atomization generator 10 based on the detection signal of the detection means 20 is provided.

  By having such a configuration, when controlling the operation of the atomization generator 10, the mist M can be sprayed only when a person uses the toilet without performing continuous operation, and deodorization / dirt decomposition can be performed. . Therefore, the mist M is not sprayed unnecessarily, leading to water / energy saving. Moreover, by detecting the person with the human detection means 20, before the odor spreads in the toilet bowl 7 or the toilet space, the mist M having deodorizing / degrading ability can be sprayed in the toilet bowl 7 or the toilet space in advance. It is possible to deodorize / decontaminate faster and more reliably.

  The control means 30 preferably controls the mist generation apparatus 10 to generate a mist M for a predetermined amount or a predetermined time when the person detection means 20 detects a person. Since the amount of mist to be deodorized / decomposed is reduced to, for example, the volume of the bowl hole of the toilet bowl 7 and the toilet bowl 7 is filled with this volume, the generation of excess mist M can be suppressed efficiently. Deodorization / dirt decomposition can be performed. In addition, the amount of mist to be deodorized / decomposed is matched to the size of the toilet room, and the deodorizing effect of the deodorized / walled odor is suppressed to a certain level, and this volume fills the toilet space with this volume. As a result, generation of excess mist M can be suppressed, so that deodorization / dirt decomposition can be efficiently performed.

  Further, the control means 30 preferably controls so that the mist M is generated from the atomization generator 10 every predetermined time when the person detection means 20 is not detecting a person, and in this case, a toilet is used. By spraying the mist M that deodorizes / decomposes dirt on the inside of the toilet bowl 7 or outside the toilet bowl 7 (toilet space) at every predetermined time when the effect of the mist M disappears or decreases during a period when there is no period, the toilet space or the toilet bowl 7 The inside can be reliably deodorized / decomposed and clean and comfortable.

  Further, the atomization generator 10 includes a liquid reservoir 1 for storing a liquid consisting of one or a combination of water, a sterilizing action, a deodorizing action, a soil decomposing action, or a fragrance, and a liquid collecting section. A liquid transport unit 2 that transports one liquid to the tip side located outside the liquid reservoir 1, an electrode 3 that is disposed so as to face the liquid transport unit 2, and between the liquid transport unit 2 and the electrode 3 And a voltage application unit 5 for applying a high voltage to the liquid transfer unit 2 to generate a mist M by atomizing the liquid in the liquid transfer unit 2 by applying a high voltage between the liquid transfer unit 2 and the electrode 3. In this case, it is possible to deodorize / decompose the attached odor and dirt using the mist M generated by atomization, so that the deodorizing / degrading of the toilet 7 and the toilet space can be performed, and the cleaner and more comfortable. It can be done.

  The present invention can deodorize / decompose adhering odors and dirt using mist generated by atomization, and can prevent mist from being sprayed unnecessarily, so that mist can be used efficiently and effectively. It is.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The toilet seat apparatus 9 of this embodiment is installed on the toilet bowl 7, as shown in FIG. The toilet seat device 9 incorporates various functional elements (not shown) such as a main body 18, a toilet seat 8, a toilet lid 19, a local cleaning device (nozzle), a hot air drying device, and an indoor heating device. In this example, a person detecting means 20 (hereinafter referred to as “human sensor 20”) for detecting a user is built in the main body 18 or a remote controller. Further, a seating sensor 21 that detects the seating of the user is built inside the main body 18 (or inside the toilet seat 8). The human sensor 20 is composed of, for example, an optical pyroelectric sensor, and the seating sensor 21 is composed of, for example, an optical distance measuring sensor. Reference numeral 22 in FIG. 1 denotes an operation switch (cleaning switch, drying switch, etc.).

  Furthermore, in this example, as shown in FIG. 4, the atomization generator 10 is built in the main body 18 of the toilet seat device 9. In addition, although the center part or side edge part inside the main body 18 etc. are mentioned as an installation location of the atomization generator 10, Of course, it is not restricted to this, The position outside the main body 18 is changeable suitably.

  As shown in FIG. 2, the atomization generator 10 includes a liquid reservoir 1 that retains liquid, an atomizing means 24 that atomizes the liquid in the liquid reservoir 1, and a mist conveying means 11 that will be described later. Yes. When the liquid is composed of a liquid that can be deodorized or sterilized or soiled by addition of electrolytic water or chemicals, or a liquid that emits a fragrance, an electrode for electrolysis or a mounting part for adding a chemical to the liquid reservoir 1 Is provided.

  The atomizing means 24 is held by a rod-shaped liquid transporting part 2 made of a plurality of porous bodies whose lower ends are immersed in the liquid reservoir 1 and whose upper ends are projected outside, and a holding part 6 made of an insulator. And a voltage applying unit 5 that applies a high voltage between the liquid conveying unit 2 and the counter electrode 3, and an electrode 3 (hereinafter referred to as “counter electrode 3”) disposed so as to face the liquid conveying unit 2. And a mist M is generated by atomizing the liquid in the liquid transport unit 2 by applying a high voltage between the liquid transport unit 2 and the counter electrode 3. In addition, as a kind of the atomizing means 24, a method of atomizing by simply ejecting a liquid, a method of atomizing by heating and evaporation, and dispersing the atomized mist M by charging the mist M with a discharge part. A system with a discharge part that improves the performance, a system that generates radicals in the mist M by cavitation when mist is generated, and an ability to effectively remove odors, bacteria, and viruses, and an electrostatic atomization system itself Any of various methods may be employed, such as a method in which mist M is charged to remove odors, bacteria, viruses and the like.

  Hereinafter, an example of the atomizing means 24 will be described. The liquid transport unit 2 is formed of a porous body and has a needle-like atomizing unit 2a with a needle-like upper end, and a plurality of liquid transport units 2 are applied in the example of FIG. It is attached to the electrode 4. These liquid transport parts 2 are arranged at equal intervals on a concentric circle centered on the center of the application electrode 4, the upper part projects upward from the voltage application part 5, and the lower part projects downward to enter the liquid reservoir 1. In contact with purified water.

  As shown in FIG. 2, the counter electrode 3 has an opening at the center, and when the edge of the opening is viewed from above, the needle-like atomization part 2 a at the upper end of the plurality of liquid transport parts 2 is A plurality of arcs R having the same diameter as the center are smoothly connected by other arcs. When the counter electrode 3 is grounded, the voltage application unit 5 is connected to the application electrode 4 to apply a high voltage, and the liquid transport unit 2 formed of a porous body sucks up water by capillary action, The needle-like atomization part 2a at the upper end of the transport part 2 functions as a substantial electrode on the application electrode 4 side, and the arc R of the counter electrode 3 functions as a substantial electrode. As the voltage application part 5, what can give the electric field strength of 700-1200 V / mm is preferable. The counter electrode 3 and the application electrode 4 are both made of a synthetic resin mixed with a conductive material such as carbon or a metal such as SUS.

  The liquid transport unit 2 is formed of a porous material that can transport water to the tip by capillary action as described above, but the counter electrode 3 is grounded and a negative voltage is applied to the application electrode 4. In this case, a material made of a material having an equipotential point that is negatively charged at the pH value of the water used is used. In addition, if the pH value of water is 7, what has a silica as a main component can be used suitably. Further, when a porous ceramic having a porosity of 10 to 60%, a particle diameter of 1 to 100 μm, and a cross-sectional shape of the tip needle-like part of φ0.5 mm or less is used as the porous body of the liquid transport unit 2, the particle diameter is A uniform mist M can be generated, and an electric field strength of 900 V / mm was given particularly when the porosity was 40%, the particle diameter was 1 to 3 μm, and the tip cross-sectional shape of the needle-like atomizing portion 2a was φ0.25 mm. Sometimes, a large amount of mist M having a particle diameter of 16 to 20 nm can be generated.

The material as described above is selected as the liquid transport unit 2 for the following reason. That is, for example, tap water, ground water, electrolyzed water, pH-adjusted water, mineral water, water containing useful components such as vitamin C and amino acids, aroma oil, fragrance, deodorant, etc. are added as the water to be atomized. When water that contains mineral components such as Ca, Mg, etc., when it is pulled up to the tip of the liquid transport unit 2 by capillary action, it reacts with CO _{2 in} the air, and the liquid transport unit 2 When the tip is made of a material having an equipotential point that is negatively charged with the pH value of the water to be used, it becomes difficult to cause electrostatic atomization by depositing and adhering as CaCO ₃ , MgO, etc. When water and the liquid transport unit 2 made of porous ceramic are in contact with each other with a negative voltage applied to the application electrode 4, the liquid transport unit 2 is negatively charged as shown in FIG. , Counter electrode 3 direction 3 is the direction indicated by the white arrow in FIG. 3, the water in the capillary in the liquid transporting part 2 which is a porous ceramic has a distribution of electrostatic potential (the zeta potential is indicated by Z in FIG. 3). Thus, an electric double layer is formed, and a so-called electroosmotic flow in the direction indicated by a in FIG. 3 is generated, and cations such as Ca and Mg are directed toward the application electrode 4 having a low potential. That is, water is pulled up in the liquid transport unit 2 in the direction of the counter electrode 3 by capillarity, but since cations such as Ca and Mg contained in the water do not go to the counter electrode 3 side, It does not cause a situation where it reacts with CO ₂ in the air at the tip and precipitates and adheres as CaCO ₃ , MgO or the like to the tip of the liquid transport unit 2. S in FIG. 3 indicates a sliding surface between the flow caused by the capillary phenomenon and the electroosmotic flow.

  Further, when the counter electrode 3 is grounded and a positive voltage is applied to the application electrode 4, a porous ceramic made of a material having an equipotential point that is positively charged with the pH value of the water used is supplied to the liquid transport unit 2. When used, when the liquid transport unit 2 is brought into contact with the water in the liquid reservoir 1 to suck up water by capillary action, the counter electrode 3 is grounded, and when the voltage is applied to the application electrode 4, this voltage is If the water located in the needle-like atomization part 2a of the liquid transport part 2 is a high voltage capable of causing Rayleigh splitting, the water in the needle-like atomization part 2a at the upper end of the liquid transport part 2 is shown in FIG. As shown, atomization is caused by Rayleigh splitting and electrostatic atomization is performed. At this time, the mist M generated by electrostatic atomization is 3 to 50 nm when the electric field strength is 700 to 1200 V / mm. In particular 3-20 nm and 30-5 nm with the intended nano-sized with a particle size of the active species (hydroxy radical, superoxide, etc.) have become one and with a strong charge amount. And such charged nano-sized mists can inactivate substances that cause pollenosis in pollen, inactivate viruses and fungi in the air, deodorize, remove airborne soot, and have anti-wrinkle effects Has an effect.

Here, the virus solution is sprayed with a sprayer from one end opening of a cylindrical container (φ55 × 200 mm) into which mist M is supplied from the atomization generator 10 that generates nano-size mist, and the virus is impinged from the other end opening. When the antiviral effect was confirmed by the plaque method after collecting in a jar, the number of plaques in the collected solution can be reduced as compared with the case where the virus is simply exposed to negative ions. Further, when E. coli O-157 was exposed to the nano-sized mist having the above-mentioned particle size, the inactivation rate was 100% after 30 minutes. This is thought to be because the active species in the nano-size mist denatures the proteins on the surface of the cells and suppresses the growth of the cells. The deodorizing effect is achieved by dissolving the odor gas in the nano-sized mist and making it non-brominated by a chemical reaction with the active species in the nano-sized mist. This deodorizing effect is a qualitative evaluation of odor intensity. I was able to confirm. The following is the deodorization reaction formula between the active species contained in the nano-size mist and the odor.
Ammonia 2NH ₃ + 6OH → N ₂ + 6H ₂
Acetaldehyde CH ₃ CHO + 6OH + O ₂ → 2CO ₂ + 5H ₂
Acetic acid CH ₃ COOH + 4OH + O ₂ → 2CO ₂ + 4H ₂
Methane gas CH ₄ + 4OH + O ₂ → CO ₂ + H ₂
Carbon monoxide CO + 2OH → CO ₂ + H ₂
Nitric oxide 2NO + 4OH → N ₂ + 2O ₂ + 2H ₂
Formaldehyde HCHO + 4OH → CO ₂ + 3H ₂ FIG. 7 shows a case where radicals are generated by applying a high voltage to water, and the radicals and odor (ammonia etc.) react to decompose. Thereby, deodorizing performance is exhibited, and sterilization or soil decomposition is also effective.

  Furthermore, when the koji mold was exposed to the nano-sized mist having the above-mentioned particle size, the result that the koji residue rate became 0% after 60 minutes was obtained. It is thought that the anti-wrinkle effect can be obtained because the OH radical decomposes the mycelium of the cocoon.

  By the way, when an electric field strength of 700 to 1200 V / mm is applied, a mist with a particle size of 3 to 20 nm and a mist with a particle size of 30 to 50 nm are often generated. When the mist having a particle diameter of 16 to 20 nm is generated at an electric field strength of 900 V / mm, each of the above effects is particularly effective. Moreover, the atomization generator 10 includes mist transport means 11 for transporting mist M generated by atomization, as shown in FIG. The mist transporting means 11 includes a path 12 for guiding the mist M generated by atomization to the inside of the toilet bowl 7 and a path 13 for guiding the mist M generated by atomization to the outside of the toilet bowl 7. The path 12 for guiding the mist M to the inside of the toilet bowl 7 is opened to the toilet inner outlet 17a of the main body 18, while the path 13 for guiding the mist M to the outside of the toilet bowl 7 is opposite to the toilet seat 8 side of the main body 18. It opens to the main body outer side discharge port 17b provided on the side. A deodorizing filter 15 is provided in the path 12 that guides the mist M to the inside of the toilet 7, and a fan 25 that blows air in the direction of the toilet 7 or outside the toilet 7 is provided in the path 13 that guides the mist M to the outside of the toilet 7. Is provided. The fan 25 can be switched in the direction of rotation by a fan motor. When the fan 25 is in communication with the atomization generator 10 as well as the air blowing means, the other is not. It also functions as switching means 14 for switching between the paths 12 and 13 so as to be in a communication state.

  The operation of the atomization generator 10 will be described. As shown in FIG. 2, the liquid reservoir 1 is made of porous ceramic, felt, or the like to suck up the liquid by capillary action. Then, by applying a negative voltage of, for example, about 5 kV between the counter electrode 3 of the high voltage electrode (minus) and the application electrode 4, the liquid is misted into a nano size by an electrostatic spray method, and further, the negative ions As shown in FIG. 1, the electric charge is charged and the fan 25 is rotated so that air is sucked from the main body outer discharge port 17b provided on the back surface of the main body 18, and the mist M is mixed with the air. Air containing mist M is discharged from the toilet inner discharge port 17a via the deodorizing filter 15 made of a deodorizing honeycomb member. On the other hand, by rotating the fan 25 in the reverse direction, as shown in FIG. 5, air is sucked from the toilet inner discharge port 17 a, mixed with the mist M and air via the deodorizing filter 15, and the air containing the mist M is removed. It has the structure which discharges from the main body outer side discharge port 17b. Here, in the present invention, as shown in FIG. 14, a human sensor 20 for detecting a person in the toilet, a seat sensor 21 for detecting a person's seating, and an operation switch 22 (washing switch, A separate mist operation switch 23, and a control means 30 for controlling the operation of the atomizing means 24 and the mist transport means 11, or switching the transport direction of the mist M, or stopping control by these sensors or switch operations. Provided. An example is shown in FIG.

  FIG. 15 shows an example in which control is performed so that mist M is generated from the atomization generator 10 for a predetermined amount or for a predetermined time based on a detection signal from the human sensor 20. When a person is detected, a predetermined amount of mist M is sprayed and filled inside or outside the toilet 7 for a predetermined time. At this time, as shown in FIG. 1, the mist M is intensively transported inside the toilet bowl 7 to deodorize the toilet bowl 7 so that no odor is leaked out of the toilet bowl 7 and at the same time, the toilet bowl 7 becomes dirty. Since (especially dirt on the rim of the toilet bowl 7) can be disassembled, the toilet bowl 7 can be cleaned. On the other hand, when the mist M is intensively transported outside the toilet 7 as shown in FIG. 5, the mist M is mixed through the built-in deodorizing filter 15 by sucking air from the inside of the toilet 7. The toilet space 16 can be sprayed and the inside of the toilet 7 can be deodorized at the same time, and the toilet space 16 can be deodorized / decomposed, so that the toilet space 16 can be made clean and comfortable. Thereafter, when the human sensor 20 detects a person leaving, the mist M is sprayed on the toilet space 16 for a predetermined time. Thereby, since the odor which leaked into the toilet space 16 can be deodorized, it can be made not to leave an unpleasant odor to a subsequent person. Also, since the mist M can be sprayed and deodorized / degraded only when a person uses the toilet without continuously operating the atomizing means 24, the mist M is not sprayed unnecessarily, and water / energy saving is achieved. Leads to.

  Here, when the mist M is sprayed on the inside of the toilet bowl 7, for example, the amount of mist to be deodorized / decomposed is reduced to the volume of the bowl hole of the toilet bowl 7, and the mist M is filled in the toilet bowl 7 with this volume. When it is made to do, since generation | occurrence | production of the excessive mist M can be suppressed, a deodorizing / dirt decomposition | disassembly can be performed efficiently. When the mist M is sprayed on the toilet space 16, the mist amount is adjusted to the size of the room of the toilet, and the deodorization / deodorizing effect of adhering odors such as walls is suppressed to a certain volume. When the toilet space 16 is filled with M, generation of excess mist M can be suppressed, so that deodorization / dirt decomposition can be efficiently performed. Furthermore, before the odor spreads in the toilet 7 or the toilet space 16 due to defecation, the odor M can be quickly and reliably sprayed on the toilet 7 or the toilet space 16 with a deodorizing / dirt decomposition performance or a fragrant mist M beforehand. Can be deodorized / decomposed.

  In addition, when the liquid in the liquid reservoir 1 is a liquid composed of one or a plurality of combinations among those having a bactericidal action, a deodorizing action, a soil decomposing action by adding electrolytic water or chemicals, or those having a fragrance Since the mist M generated by atomization can deodorize / decompose the adhering odor and dirt or a fragrance, the mist M in the toilet 7 and the toilet space 16 can be deodorized / degraded, or a fragrance can be produced. So it can be more clean and comfortable. Furthermore, you may provide the discharge part (not shown) which charges the electric charge of a negative ion to the atomized mist M. In this case, the mist M can be charged by discharging, and the mist M is split by the charge and becomes smaller, so that the diffusibility can be improved. That is, electrostatic diffusion occurs, and odors, fungi, and viruses can be more effectively removed by diffusing static electricity into the space.

  As another control, as shown in FIG. 16, when the seating sensor 21 detects the seating of a person, the mist M is intensively sprayed on the inside of the toilet bowl 7, so that the smell of defecation / urination is reduced inside the toilet bowl 7. Can deodorize / decompose dirt or produce fragrance. Also, by spraying the mist M intensively outside the toilet 7 for a predetermined time after the person leaves (or until the person leaves the toilet space 16 or includes a predetermined time after leaving), By deodorizing / decomposing odors and adhering odors that have leaked into the toilet space 16 or by giving out a fragrance, it is possible to prevent odors from being left behind. Also in this case, spraying of unnecessary mist M can be eliminated as in the case of FIG. Further, depending on the case, it is possible to identify butt washing, bidet washing, etc., and increase the mist generation amount only when the butt washing operation switch 22 is operated, and reduce the mist generation amount when the bidet washing operation switch 22 is operated. By reducing the mist generation tatami per unit time, it is possible to prevent generation of useless mist.

  Further, as another control, the operation of the atomization generator 10 is controlled by a combination of the human sensor 20, the seating sensor 21, and the operation switch 22 (cleaning switch, drying switch, etc.), the transport direction of the mist M is switched, or You may enable it to perform stop control. An example is shown in FIG. In this example, when a person enters the toilet and sits on the toilet seat 8, the mist M having deodorizing / degrading ability or the mist M capable of producing a fragrance is intensively sprayed on the inside of the toilet 7 and is seated on the toilet seat 8. Since the spraying of mist M can be stopped or the amount of mist can be reduced, the toilet seat user can quickly and surely deodorize / decompose dirt or give a fragrance without feeling the “hyat feeling” by the mist M. it can. In addition, after the stool, until the user leaves the toilet and leaves the toilet, the spraying of the mist M to the toilet space 16 is stopped or the amount of mist is reduced, and the predetermined amount after the user leaves the toilet. If the user stays in the toilet only for a certain period of time, the deodorizing / degrading can be done quickly and surely, or the fragrance can be given out without “cool feeling”. Control becomes possible. Also in this example, the atomization generator 10 need not be operated continuously, which leads to water / energy saving.

  As another control, as shown in FIG. 18, the user himself / herself operates another mist operation switch 23 when necessary to spray the mist M inside the toilet bowl 7 or outside the toilet bowl 7 (toilet space 16). You may do it. In this case, when the user needs it, the mist M for deodorizing / degrading dirt or the mist M for producing fragrance can be generated inside the toilet bowl 7 or outside the toilet bowl 7 as necessary. Sometimes the mist M can be sprayed and cleaned inside the toilet bowl 7, and when the odor after defecation is unavoidable, the user himself increases the mist M to the toilet space 16 and the It is possible to avoid leaving odors.

  As another control, as shown in FIG. 19, when the human sensor 20 does not detect a person, the mist M may be controlled to be generated from the atomization generator 10 every predetermined time. . In this example, in a state where the human sensor 20 does not detect a person, the mist M is sprayed on the inside of the toilet bowl 7 or the outside of the toilet bowl 7 (toilet space 16) every elapse of a predetermined time. As a result, even during a period when the toilet is not used, every time a predetermined time elapses when the effect of the mist M disappears or decreases, the inside of the toilet 7 or the outside of the toilet 7 (toilet space 16) deodorizes / decomposes or fragrance is produced. Mist M can be sprayed, and deodorization / dirt decomposition can be performed or fragrance can be surely ensured inside the toilet space 16 or the toilet bowl 7 at all times. Therefore, it is always clean and comfortable, and you can always use the toilet comfortably.

  In FIGS. 15 to 19, the mist occurrence time is set to a predetermined time. However, in order to control the amount of mist generation such as “large”, “medium”, and “small”, the occurrence time is selectively set to “long”, “medium”. “Short” may be changed, or the mist generation amount per unit time may be changed to “Large”, “Medium”, and “Small” by a predetermined time. Further, the mist generation control by the human sensor 20 and the seating sensor 21 has been described with respect to an example in which the mist is activated both before and after the stool, and the operation of spraying the mist M on both the inside and outside of the toilet 7. The operation may be performed only before the stool or only after the stool, or the mist may be generated only in the toilet 7 or only in the toilet space 16.

  8 to 13 show other embodiments of the mist conveying means 11. First, in FIG. 8 and FIG. 9, the mist M discharge direction switching means 14 is switched by louver rotation control, and a fan 25 is disposed in front of the louver. In this case, the mist M that can be deodorized / decomposed or fragrant can be efficiently diffused / filled in the relatively narrow toilet space 16 or the toilet bowl 7 that is easily soiled only by switching the louver. Can be kept clean and comfortable. Moreover, you may simplify a structure by removing a deodorizing filter. Furthermore, as shown in FIGS. 10 and 11, the inside of the toilet 7 and the toilet space 16 can be switched only by rotation control of the fan 25 instead of the louver.

  12 and 13, the deodorizing filter 15 is installed between the atomizing means 24 and the main body outer discharge port 17 b, and the fan 25 is installed upstream of the deodorizing filter 15. In this example, since the deodorizing filter 15 is disposed in the path 13 for transporting the mist M outside the toilet bowl 7 and the fan 25 is installed in front of it, the fan 25 is simply rotated so that the inside of the toilet bowl 7 as shown in FIG. By spraying the mist M, the deodorization inside the toilet bowl 7 can be reliably performed. Further, when the mist M is transported to the toilet space 16 as shown in FIG. 13, the fan 25 is rotated in the reverse direction so that the odor inside the toilet 7 is taken into the mist M and mixed with the mist M to deodorize, and then further deodorized. After deodorizing by the filter 15, the odor inside the toilet bowl 7 is not leaked to the toilet space 16 by discharging it into the toilet space 16, and the toilet space 16 can be deodorized. Further, unlike FIG. 1, the deodorizing filter 15 is provided in the path 13 for guiding the mist M to the outside of the toilet bowl 7, so that the odor inside the toilet bowl 7 and the mist M having a deodorizing function are mixed and deodorized. Furthermore, since the deodorizing filter 15 deodorizes, the deodorizing performance is further improved.

  In each of the above embodiments, the toilet seat device 9 and the atomization generating device 10 are integrated. However, the toilet device 7 may be attached to the toilet bowl 7 instead of the integrated type. Is possible. Moreover, the form which generate | occur | produces bubble-like foam may be sufficient as the mist generation | occurrence | production inside the toilet bowl 7. FIG. Further, as the fan 25 of the mist conveying means 11, a drying device and a blower fan (not shown) of the room heating means may be shared.
