Description

TOILET DEVICE AND TOILET SEAT DEVICE}

Aspects of the present invention generally relate to a toilet device and a toilet seat device.

In the boiler apparatus of patent document 1, mist of hypochlorous acid water or tap water is sprayed automatically into the bowl of a toilet bowl before using a toilet apparatus (for example, when a human body detection sensor detects a human body). Thereby, a water film is formed in a bowl part, and adhesion and fixation of the dirt to the bowl part surface can be suppressed.

Japanese Patent No. 5029930

On the inner surface of the bowl part of the toilet bowl, there is a washing area through which the washing water for discharging the dirt in the bowl part to the outside, and a non-cleaning area located above the washing area and not passing through the washing water. In such a non-clean region, dirt may adhere. For example, dirt splashed in the cleaning region may adhere to the non-clean region. Therefore, in order to suppress contamination occurring in a wide range of toilets including not only the cleaning region but also the non-cleaning region, it is preferable to start the mist not only in the cleaning region but also in the non-cleaning region. However, there is room for improvement in the viewpoint of suppressing generation | occurrence | production of the microorganism and contamination in a non-clean area | region because the amount of mist which starts in a non-clean area | region in the toilet apparatus of patent document 1 is small. On the other hand, by automatically spraying a mist of tap water or germicidal water over a wide range including a non-cleaning area, it is possible to suppress the generation of germs and contamination by dirt (such as excretion of the user) over a wide range. Thereby, for example, the frequency of cleaning of a user can be reduced.

On the other hand, tap water may contain scale components, such as sodium, calcium, potassium, and magnesium. In this case, the scale component is contained also in the mist of tap water and the mist of the germicidal water produced | generated from tap water. For this reason, when using mist of tap water or the bactericidal water produced from tap water, the scale (for example, calcium carbonate) may precipitate by mist evaporating after the mist has started to the boiler apparatus.

The scale component of the mist adhering to the cleaning area of the toilet is cleaned by the washing water flowing in the toilet to discharge the dirt in the toilet. However, the scale component of the mist adhering to the non-clean region of the toilet is not washed by the washing water flowing in the toilet. Therefore, when mist of tap water or germicidal water is sprayed into the non-clean area, scale may gradually grow in the non-clean area, resulting in visible contamination in a short period of time.

Scalding contamination due to scale components of such tap water can be removed by wiping off. However, when scale contamination occurs in a short period of time, when the mist of germicidal water is automatically sprayed to a wide range including a non-clean area for the purpose of reducing the frequency of cleaning, The problem arises that the frequency cannot be reduced.

The present invention has been made on the basis of the recognition of such a problem, and it is possible to suppress the occurrence of microorganisms and contamination in a wide range of toilets including a non-clean area, and to generate visible pollution in a short time in the non-clean area. An object of the present invention is to provide a restrained toilet device and a toilet seat device.

According to a first aspect of the present invention, there is provided a bowl portion receiving dirt, an upper surface of a rim positioned on the bowl portion, and a water jet port for discharging washing water for discharging the dirt from the bowl portion into the bowl portion.

When the user is in a state of detecting, the spray device is automatically controlled to generate mist from the cleaning area and The user is sprayed into the non-clean area, and the mist is retained in the cleaning area and the non-clean area to form water droplets or water film, and the user is not detected from the state where the detection sensor detects the user. The spraying device is automatically controlled when it is in a non-active state so as to launch mist into the water drop or the water film formed in the non-clean area in the pre-mist mode, and increase the water drop or the water film volume to increase the water drop or the water film. It is a toilet device characterized in that it is possible to execute the after-mist mode for washing the water film.

According to this boiler apparatus, mist sprayed from the spray apparatus in the pre-mist mode forms a water droplet or a water film in the washing region and the non-clean region. As a result, it is possible to suppress adhesion and adhesion of dirt over a wide range in the bowl portion including the non-clean region. In addition, the mists that have started remain in the cleaning and non-cleaning areas, and the water droplets or the water film are not washed, for example, after the after-mist mode is executed. This makes it possible to further suppress the adhesion and seizure of dirt compared to the case where only the bowl part is wet.

In the after-mist mode, the mist of the bactericidal water sprayed from the spraying device starts in the non-clean region. Thereby, generation | occurrence | production of the microbe and contamination by the dirt which was not wash | cleaned with the washing water can be suppressed.

In addition, when the water droplet or the water film formed by the pre-mist mode exists in the non-clean area | region, the scale may precipitate by the evaporation of the water or water film, and soil contamination may arise in the non-clean area | region. On the other hand, it can suppress that a water droplet or a water film | membrane remains in a non-clean area | region by washing | cleaning the water droplet or water film | membrane formed in the non-clean area | region by the after mist mode. As a result, generation of scale contamination can be suppressed. As mentioned above, while generation | occurrence | production of microorganisms and contamination in the wide range of the toilet containing a non-clean area | region is suppressed, generation of visible pollution in a short time in a non-clean area can be suppressed.

According to a second aspect of the present invention, there is provided a bowl portion receiving dirt, an upper surface of a rim positioned on the bowl portion, and a water jet port for discharging washing water for discharging the dirt from the bowl portion into the bowl portion. A toilet seat is provided on an upper part of a toilet having a washing area through which washing water passes and a non-cleaning area located above the washing area and below the upper surface of the rim, wherein the user seats and the spray device sprays mist. And a detection sensor that detects the user, and a control device that controls the spraying device based on detection information of the detection sensor, wherein the control device is configured from the state in which the detection sensor does not detect the user. When the user is in a state of detecting the mist, the spray device is automatically controlled to remove mist from the washing area. The user is sprayed into the non-cleaned area, retains mist in the cleaning area and the non-cleaned area to form a water drop or water film, and the user is not detected from the state where the detection sensor detects the user. The spraying device is automatically controlled when it is not in operation, the mist or water film formed in the non-cleaned area in the pre-mist mode is launched, and the water drop or water volume is increased by increasing the volume of the water film or the water film. It is a toilet seat apparatus characterized in that it is possible to execute the after-mist mode for washing the water film.

According to this toilet seat apparatus, mist sprayed from the spray apparatus in the pre-mist mode forms a water droplet or a water film in the washing region and the non-clean region. As a result, it is possible to suppress adhesion and adhesion of dirt over a wide range in the bowl portion including the non-clean region. In addition, the mists that have started remain in the cleaning and non-cleaning areas, and the water droplets or the water film are not washed, for example, after the after-mist mode is executed. This makes it possible to further suppress the adhesion and seizure of dirt compared to the case where only the bowl part is wet.

In the after-mist mode, the mist of the bactericidal water sprayed from the spraying device starts in the non-clean region. Thereby, generation | occurrence | production of the microbe and contamination by the dirt which was not wash | cleaned with the washing water can be suppressed.

In addition, when the water droplet or the water film formed by the primitive mode remains attached to the non-clean area, the water droplet or the water film may evaporate, causing the scale to precipitate, resulting in contamination when the water is in the non-clean area. On the other hand, it can suppress that a water droplet or a water film | membrane remains in a non-clean area | region by wash | cleaning the water droplet or water film | membrane formed in the non-clean area | region by the after mist mode. As a result, generation of scale contamination can be suppressed. As mentioned above, while generation | occurrence | production of microorganisms and contamination in the wide range of the toilet containing a non-clean area | region is suppressed, generation of visible pollution in a short time in a non-clean area can be suppressed.

The third invention has a bowl portion receiving dirt, an upper surface of the rim positioned on the bowl portion, and a water discharge port for discharging the cleaning water for discharging the dirt from the bowl portion into the bowl portion, wherein the bowl portion is A toilet having a washing area through which the washing water passes and a non-cleaning area located above the washing area and below the upper surface of the rim, a seating unit installed on the toilet seat, and spraying mist And a detection sensor that detects the user, and a control device that controls the spraying device based on detection information of the detection sensor, wherein the control device is configured from the state in which the detection sensor does not detect the user. Primer which sprays mist by automatically controlling the said spraying device when it becomes the state which detects a user A mist mode is feasible, and the pre-mist mode includes a first step of forming a water drop or a water film by injecting mist into the non-clean area, and the water drop or the water film formed in the non-clean area in the first step. And a second step of washing the water drop or the water film by launching a mist and increasing the water drop or the volume of the water film.

According to the toilet device, the cleaning area and the non-clean area can be wetted by the mist mode before use of the user's toilet device. As a result, it is possible to suppress adhesion and adhesion of dirt over a wide range in the bowl portion including the non-clean region.

If the water droplet or water film formed by the primitive mode remains attached to the non-clean area, the scale may precipitate due to evaporation of the water or water film, and contaminants may occur in the non-clean area. On the other hand, it can suppress that a water droplet or a water film | membrane remains in a non-clean region by washing | cleaning the water droplet or water film formed in the non-clean area | region by a 2nd process. As a result, generation of scale contamination can be suppressed. As mentioned above, while generation | occurrence | production of microorganisms and contamination in the wide range of the toilet containing a non-clean area | region is suppressed, generation of visible pollution in a short time in a non-clean area can be suppressed.

Moreover, in mist mode, when mist is sprayed so that the mist started may flow immediately, there exists a possibility that mist may splash in a bowl part and it may scatter out of a toilet because the mist size and flow volume are large. On the other hand, in this invention, after forming a water drop or a water film by a 1st process, the water drop or a water film is made to fall by increasing the volume of a water drop or a water film by a 2nd process. As a result, mist can be prevented from scattering out of the toilet.

When the user sits on the seating part 200, the tact switch is pressed down by the weight of the user. Or, the user contacts the electrostatic sensor. Alternatively, pressure is applied to the deformation sensor by the weight of the user. The user's seat can be detected by the electrical signals from these sensors.

The human body detecting sensor 403 may detect a user who is in front of the toilet 800, that is, a user who is present at a position spaced forward from the seating unit 200. That is, the human body detecting sensor 403 may detect a user who has entered the toilet and has approached the seating unit 200. As such a human body detection sensor, a pyroelectric sensor, a microwave sensor, an ultrasonic sensor, or a ranging sensor (infrared light transmissive sensor) can be used, for example. In this example, the pyroelectric sensor provided in the casing is used for the human body detection sensor 403. In addition, the human body detection sensor 403 may detect a user immediately after entering the toilet by opening the door of the toilet, or a user immediately before entering the toilet, that is, a user who is present in front of the door in order to enter the toilet. For example, when a microwave sensor is used, it becomes possible to detect the presence of a user over the door of the toilet.

The control device 405 receives the detection information (signal indicating the presence or absence of the user) of the human body detection sensor 403 or the detection information (signal indicating the presence or absence of the user's seating) of the seating detection sensor 404, The operation of each part of the toilet seat apparatus 100 is controlled based on the received detection information.

The control device 405 can execute three types of mist modes, an after-mist mode, a pre-mist mode, and a manual mist mode.

The after-mist mode is an operation mode which automatically sprays mist of the germicidal water based on the detection information of the detection sensor 402 after use of the user's toilet device 10, for example. The pre-mist mode is an operation mode which automatically sprays mist of the bactericidal water or tap water based on the detection information of the detection sensor 402, for example, before use of the user's toilet device 10. Manual mist mode is an operation mode which sprays mist of the germicidal water based on the operation information of the manual operation part 500.

5 (a) to 5 (e) are a plan view and a perspective view illustrating the toilet device according to the embodiment.

5 (a) shows a state of a part of the toilet device 10 viewed from the front.

FIG. 5B is an enlarged view of a part of FIG. 5A. In addition, in FIG.5 (b), the part of the casing 400 located in front of the spraying apparatus 481 is abbreviate | omitted in order to make it easy to see.

The spraying device 481, the nozzle damper 479, and the blowing damper 516 are located at the upper rear side of the bowl portion 801 in the state where the toilet seat apparatus 100 is installed on the toilet bowl 800.

The nozzle damper 479 is pivotally supported relative to the casing 400. The nozzle 473 is located behind the nozzle damper 479 in the state of retreating into the casing 400. At the time of washing of the human private parts, the nozzle 473 contacts the nozzle damper 479, rotates the nozzle damper 479 to open, and advances from the inside of the casing 400.

5C to 5E are perspective views showing enlarged peripheries of the nozzle damper 479 and the blowing damper 516.

The blowing damper 516 is pivotally supported relative to the casing 400. A blower 513 is disposed behind the blower damper 516. Blowing damper 516 covers opening 516a of casing 400. Air sent from the blower 513 is sent into the toilet 800 through the opening 516a.

5C is a state in which the blower 513 has stopped operating, and FIGS. 5D and 5E show that the blower 513 operates to blow air toward the bowl 801. Indicates the state. As shown in Fig. 5C, the blowing damper 516 is closed in the state in which the blowing is stopped.

As shown in FIG. 5D, when the blower 513 is operated, the blower damper 516 is rotated and opened by the pressure (wind pressure) of the air sent from the blower 513. Thereby, the blower 513 blows toward the front lower part in the bowl part 801 from the rear upper part in the bowl part 801 like arrow A1, for example.

In the state of FIG. 5E, the amount of air sent by the blower 513 is larger (or the wind speed is higher) than the state of FIG. 5D. In this case, the blower damper 516 is further rotated and opened compared with the state of FIG. 5 (d). Thereby, the blower 513 blows toward the front upper part in the bowl part 801 from the rear upper part in the bowl part 801 like arrow A2.

In this way, the direction of the wind sent from the blower 513 is changed by the blower damper 516. In other words, the blowing device 513 can control the blowing direction by the air volume (wind speed). The range where the mist starts by burning the mist sprayed from the spraying device 481 in the airflow generated by the blowing from the blower 513, and the amount of the mist to be started in each range (the germicidal water undertaken in each range or The amount of tap water) may be controlled.

6 (a) to 6 (c) are schematic diagrams illustrating the spraying apparatus according to the embodiment.

FIG. 6A is a perspective view of the spray device 481, and FIG. 6B is a side view of the spray device 481.

The spraying apparatus 481 has the motor 481a and the disk 481b connected below the motor 481a. Rotation of the motor 481a is controlled by the control device 405. When the motor 481a rotates, the driving force of rotation is transmitted to the disk 481b, and the disk 481b rotates.

As shown in FIG. 6B, water W (tap water or germicidal water generated by the germicidal device 450) is supplied to the upper surface of the disk 481b. During the rotation of the disk 481b, the water W is supplied so that the spraying device 481 sprays the water W into a mist shape.

6C is an enlarged view of a portion of the disk 481b viewed from above. Water W dropped on the upper surface of the rotating disk 481b spreads in a film form on the disk 481b by centrifugal force and is radiated from the disk 481b. At this time, the water W is split from the vicinity of the edge of the disk 481b in the form of a film, or is broken after being formed into a yarn shape, and thereafter becomes fine particles p (mist). By the rotational speed of the disk 481b, that is, the rotational speed of the motor 481a, the particle diameter of the mist (the diameter of the fine particles p) can be controlled. The higher the rotation speed, the smaller the particle diameter of the mist. For example, a low speed rotation with a rotation speed of about 1000 (rotation per minute (rpm)), a medium speed rotation with a rotation speed of about 10000 rpm, or a high speed rotation with a rotation speed of about 20000 rpm is appropriately used, and a desired particle size is obtained. In addition, the particle size of the mist can be controlled by adjusting the flow rate of the water W supplied from the water supply port 481c to the spraying device 481.

In addition, in this specification, particle size is the particle diameter of the microparticles | fine-particles p which exist in the air before starting to the toilet apparatus 10, for example, a Sauter average particle diameter (total volume / total surface area). The measuring method of "particle diameter" in this specification is mentioned later with respect to FIG. In addition, mist refers to the range whose particle diameter is 10 micrometers (micrometer) or more and 300 micrometers or less. If the particle diameter of the mist is less than 10 µm, a long time is required to wet the target sites such as the bowl 801, the rim 805, the seat 200, and the like. In addition, when the bactericidal water containing hypochlorous acid is used, when the particle diameter of mist is less than 10 micrometers, the density | concentration of the hypochlorous acid in mist is easy to attenuate, and sterilization performance will fall easily. On the other hand, when the particle diameter of mist is larger than 300 micrometers, it becomes difficult to diffuse mist and it becomes difficult to spray mist over a wide range. In addition, in the following description, the mistran particle diameter of a large particle size is 100 micrometers or more and 300 micrometers or less, Preferably it is the mist of the range of 150 micrometers or more and 300 micrometers or less. Preferably it is the mist of the range of 60 micrometers or more and 150 micrometers or less, and the mist of a small particle size is the mist of the range whose particle diameters are 10 micrometers or more and 100 micrometers or less, Preferably they are 10 micrometers or more and 60 micrometers or less.

For example, the particle size of the mist sprayed from the spraying device 481 into the toilet 800 by the position or number of the water supply port 481c, the rotational direction (clockwise or counterclockwise) of the disk 481b, It is also possible to adjust the flow rate, the direction and the like. Thereby, you may control the range which the mist sprayed from the spraying apparatus 481 starts, and the impingement amount of mist in each range. In addition, a cover or the like for controlling the direction in which mist is sprayed may be appropriately formed around the disk 481b.

7 is a cross-sectional view illustrating a part of the toilet apparatus according to a modification of the embodiment.

FIG. 7: shows the cross section in the AA 'line shown to FIG. 5 (a).

As shown in FIG. 7, the slit S is provided in the casing 400. In this example, the spraying device 481 is disposed in the casing 400, and the slit S is located at the front lower portion of the spraying device 481. For example, the height (position in the vertical direction) of the top surface S1 of the slit S is equal to the height of the bottom surface B1 of the disk 481b, and the top surface S1 and the bottom surface B1. ) Are coplanar. Alternatively, the top surface S1 may be lower than the bottom surface B1.

The upper surface of the disk 481b is inclined from the horizontal, and the disk 481b sprays the mist M downwardly rather than horizontally. Mist sprayed from the disk 481b passes through the slit S and is sprayed into the bowl portion 801. Thereby, contamination Y, such as urine, can be prevented from adhering to the spraying apparatus 481, without impairing the design or cleaning property of the toilet apparatus 10. FIG. In addition, the disk 481b may have a flat disk shape, may be provided with irregularities, or may use a conical shape or sphere. Thereby, the spray direction of mist, the particle diameter of mist, etc. can also be adjusted.

The spray device 481 is disposed below a part of the seating part 200 in a state where the toilet seat device 100 is installed above the toilet bowl 800 (see FIG. 2), and the mist is directed toward the toilet bowl 800. Spray.

In addition, in embodiment, the spraying device is not limited to the apparatus demonstrated with respect to FIG. 6 and FIG. For example, you may use an ultrasonic atomizer as a spraying device. An ultrasonic atomization apparatus makes a liquid mist-shaped by irradiating an ultrasonic wave with a liquid. Further, for example, a two-fluid nozzle may be used as the spraying device. The two-fluid nozzle makes the liquid into a mist shape by injecting a gas and a liquid together. However, when using the apparatus demonstrated with respect to FIG. 6 and FIG. 7, there exists a merit which is easy to control spray range by the blower 513. FIG. In addition, the risk of clogging is low, and an auxiliary device such as a compressor is also unnecessary.

8 (a) to 8 (c) are perspective views illustrating another toilet device according to the embodiment.

In this example, the mist damper 482 is provided in front of the spraying device 481. The mist damper 482 covers the slit S in front of the spraying apparatus 481 in a closed state.

The mist damper 482 is fixed to the nozzle damper 479, for example, and cooperates with the nozzle damper 479. The mist damper 482 is also opened by opening the nozzle damper 479, and the mist damper 482 is also closed by closing the nozzle damper 479.

8B and 8C show enlarged peripheries of the nozzle damper 479 and the mist damper 482. 8B illustrates a state in which the nozzle 473 is retracted into the casing 400. At this time, the nozzle damper 479 is in a closed state and covers the front of the nozzle 473. In addition, the mist damper 482 is in a closed state and covers the front of the slit (S).

When the spraying device 481 is not used, the spraying device 481 is concealed from the bowl part 801 side by the mist damper 482 as shown in FIG. This can further prevent urine or contamination from adhering to the spray device 481.

8C shows a state where the nozzle 473 advances forward and the nozzle damper 479 is rotated. The advancing distance to the front of the nozzle 473 at this time may be shorter than the advancing distance to the front at the time of a local body washing | cleaning. For example, the tip of the nozzle 473 is in contact with the nozzle damper 479. In addition, in FIG. 8C, the mist damper 482 is rotated and opened together with the nozzle damper 479. The mist damper 482 may control the direction or range in which mist is sprayed.

9 is a flowchart illustrating the operation of the toilet seat apparatus according to the embodiment.

10 (a) and 10 (b) are schematic diagrams illustrating the operation of the toilet seat apparatus according to the embodiment.

10 (b) shows the target sites P1 to P4 to which the mist of the germ-free water or the tap water starts. Fig. 10A shows an example of the amount of impingement (the amount of impingement per unit area) of each target site in each mist mode in four stages of "large", "medium", "small", and "minimal".

The control device 405 automatically controls the spraying device 481 when the detection sensor 402 is in a state of detecting the user from the state in which the detection sensor 402 is not detecting the user, and the mist of tap water or the mist of germ-free water is bowled. A primitive mode of spraying in 801 is feasible.

For example, as shown in FIG. 9, when a user enters a toilet and the human body detection sensor 403 detects a user's entrance, the signal (detection information) which shows the user's entrance is transmitted to the control apparatus 405. FIG. The control device 405 automatically executes the primitive mode based on the signal. In the pre-mist mode, the control device 405 sprays mist of tap water onto the spraying device 481 to launch the mist at the target site. As shown in Figs. 10 (a) and 10 (b), the target site in the primitive mode is the target site P3 (the non-clean region 801B of the bowl 801) and the target site P4 ( Cleaning area 801A of the bowl portion 801). In the pre-mist mode, the rim upper surface 806 of the seating part 200 and the rim part 805 is not a target part of spraying.

Thus, mist sprayed from the spraying device 481 in the premist mode starts not only the cleaning area 801A but also the non-cleaning area 801B to form a water film in the cleaning area 801A and the non-cleaning area 801B. . Thereby, adhesion and seizure of the dirt can be suppressed in the wide range of the toilet bowl 800 including the non-cleaning area 801B.

The control device 405 automatically controls the spraying device 481 when the detection sensor 402 detects the user and does not detect the user, thereby controlling the mist of the germ-free water in the toilet 800 and An after-mist mode spraying onto the seating unit 200 is feasible.

For example, as shown in FIG. 9, when the user leaves the toilet and the human body detection sensor 403 detects the user's departure, a signal (detection information) indicating the user's departure is transmitted to the control device 405. The control device 405 automatically executes the after-mist mode based on the signal. In the after-mist mode, the control apparatus 405 produces | generates the germicidal water in the germicidal apparatus 450, sprays the mist of the germicidal water into the spraying apparatus 481, and sets the mist in the target site | part. As for the target site | part in the after-mist mode, as shown to FIG. 10 (a) and FIG. 10 (b), target site | part P1 (surface 203 of the seating part 200) and target site | part P2 (seat part) Rear surface 204 and rim upper surface 806 of 200, target site P3, and target site P4.

In this way, after the use of the toilet seat apparatus 100 of the user by the execution of the after-mist mode, the sterile water can be automatically started in the toilet 800 and the seating unit 200. Thereby, generation | occurrence | production of a microbe and contamination can be suppressed automatically in the wide range not only toilet seat 800 but seating part 200 grade | etc.,.

The control device 405 can execute the manual mist mode in which the spraying device 481 is sprayed when the user operates the manual operation unit 500 to spray mist of the sterile water into the toilet 800 and the seating unit 200. Do.

For example, as shown in FIG. 9, when a user operates the manual control part 500 while entering the toilet (for example, after execution of the primitive mode), the signal (operation information) according to an operation will be controlled. Is sent). The control device 405 executes the manual mist mode based on the signal. The manual mist mode is executed at timings such as before, after use, and cleaning of the toilet seat apparatus 100. In the manual mist mode, the control device 405 generates the germicidal water in the germicidal device 450 and sprays the mist of the germicidal water into the spraying device 481 to launch the mist at the target site. The target site | part in the passive mist mode is the target site | part P1, the target site | part P2, the target site | part P3, and the target site | part P4, as shown to FIG.10 (a) and FIG.10 (b).

Thus, by starting the germicidal water in the toilet 800 and the seating unit 200 at the timing when the manual operation unit 500 is operated by the manual mist mode, a wide area including the seating unit 200 as well as the toilet seat 800. In the range, the occurrence of bacteria and contamination can be suppressed. In addition, the user can remove germs or contamination generated in the seating unit 200 by wiping the mist of the germicidal water impinged on the seating unit 200. For example, sterilization can be performed by wiping the germicidal water undertaken against sticking contamination, which is difficult to be suppressed by the after-mist mode, using a toilet paper or the like. In addition, for example, a user who is concerned about contamination of the seating unit 200 before use of the toilet seat apparatus 100 can sterilize the seating unit 200 by the manual mist mode. Since the sterilization is carried out based on the user's own operation, the user's security and satisfaction can be increased.

It is sectional drawing which illustrates operation | movement in the primitive mode of the toilet seat apparatus which concerns on embodiment.

As shown in FIG. 11, the non-clean region 801B of the bowl portion 801 has a front-side non-clean region 801F. The front end side non-clean region 801F is the front end of the non-clean region 801B, and is located at the center of the bowl portion 801 in the left and right directions, for example. The front end side non-clean region 801F is an area including the foremost end of the non-clean region 801B and extends up and down from the upper end of the cleaning region 801A to the rim upper surface 806.

In order to suppress adhesion of dirt and the like in the bowl portion 801, it is preferable to start a lot of mist so that a water film is also formed in the non-clean region 801B. Therefore, a method of operating the blower 513 to generate airflow in the bowl portion 801 and sending the mist to the non-clean region 801B by the airflow is considered. However, in this case, the mist carried by the airflow may also embark on the seating part 200 or the rim upper surface 806. Then, when the user has seated on the seating part 200 or when the seating part 200 is rotated by hand, the user's buttocks or hands may come in contact with the mist impinged on the seating part 200 and may cause discomfort. In addition, since the rim upper surface 806 is formed substantially horizontally, there exists a possibility that the mist which started on the rim upper surface 806 may fall out of the toilet bowl 800. As shown in FIG.

Therefore, the control device 405 does not operate the blower 513 which generates the raised airflow in the bowl part 801 in the premist mode. Further, in the pre-mist mode, the control device 405 sprays the spray device to directly launch the mist into the front end-side non-clean region 801F without mist falling on the rim upper surface 806 falling out of the toilet bowl 800. The speed of mist sprayed by the spraying device 481 is controlled so that the mist sprayed from 481 reaches the front end side non-clean region 801F while maintaining the straight state.

As a result, the mist does not float in the rising air flow generated by the blower 513 while the mist is started in the non-cleaning region 801B, so that the mist starts to the upper surface 806 or the seating portion 200. The amount of mist to be suppressed can be suppressed. As a result, mist falling on the rim upper surface 806 can be prevented from falling out of the toilet bowl 800. In addition, the seating part 200 can be suppressed from being wet by the mist, and when the user sits on the seating part 200 or when the seating part 200 is rotated by hand, the user's buttocks and hands are held by the seating part ( It is possible to suppress contact with the mist started at 200).

In addition, in this specification, the "initiated mist" includes the water droplet and water film formed by aggregating after mist starts.

For example, in the pre-mist mode, the control device 405 controls the rotation speed of the disk 481b of the spraying device 481 to adjust the speed of the mist (the speed at which the fine particles p fly) and the particle diameter of the mist. To control. For example, the higher the speed of mist, the easier the mist is to stay straight.

In FIG. 11 (and FIGS. 14, 17, 20, 24, 25, 27, 28, 30, and 31 to be described later), the path of the mist M sprayed from the spraying device 481 is indicated by an arrow. It is represented by. The thicker the arrow, the larger the amount of mist. As shown in FIG. 11, the range in which mist is sprayed spreads up and down.

It is a schematic diagram which illustrates the mist sprayed by the spraying apparatus which concerns on embodiment.

The particle diameter of mist sprayed from the spraying device 481 has a distribution. For example, as shown in FIG. 12, from the spraying apparatus 481, mist M1 of small particle size (fine particle p1 of tap water or sterile water), and mist M2 of medium or large particle diameter (tap water or bactericidal) A number of fine particles p2) are sprayed. The fine particles p2 of the mist M2 tend to progress horizontally or downward because their own weight is large. On the other hand, since the microparticles | fine-particles p1 of mist M1 have small weight, they may advance upward by the influence of airflow.

For this reason, as shown in FIG. 11, distribution also arises in the quantity of mist which starts in the front side non-clean region 801F. The portion where the most mist directly starts among the front end non-clean regions 801F is the volume zone BZ. In the embodiment, the control device 405 controls the spraying device 481 so that the mist reaching the volume zone BZ is kept straight.

It is a schematic diagram for demonstrating the straight state of mist.

It is determined as follows whether or not the mist sprayed from the spraying device 481 maintains the straight state.

The spray object OB is disposed at a position spaced apart by the distance L in the horizontal direction from the spray device 481 (disk 481b). The distance L is the distance (about 300-400 mm) along the horizontal direction between the spraying apparatus 481 and the front end side non-cleaning area 801F, for example.

Mist is sprayed on the spray object OB from the spraying apparatus 481, and the impinging point Pt1 of the mist in the spray object OB is measured. The starting point Pt1 is a point at which the most mist of the spray object OB directly starts. For example, the start point Pt1 can be visualized by receiving a mist from a sensitized test paper or a transparent plate and observing the distribution of water droplets.

The spraying device 481 measures the spraying direction Ds (spray angle? S) at which the mist is sprayed. The spraying direction Ds is a direction in which the most mist is sprayed in the vicinity of the spraying device 481. In addition, with the vicinity of the spraying apparatus 481, the distance from the spraying apparatus 481 is the range of 50 mm or less, for example. For example, the spray direction Ds acquires the image of the spraying apparatus 481 which sprays mist, and can measure it by image processing. Alternatively, the mist sprayed may be visualized by irradiating the sheet laser to the mist, and the spraying direction Ds may be measured. The spray angle θs is the angle between the horizontal direction and the spray direction Ds.

The height h1 of the intersection point Pt2 of the straight line L1 extending in the spraying direction Ds from the spraying device 481 and the spray object OB is calculated. The height h1 is a distance along the vertical direction between the spraying device 481 and the intersection point Pt2, and is calculated by L × tanθs. In addition, the actual impingement height h2 is measured. The impingement height h2 is the distance along the up-down direction between the spraying device 481 and the impinging point Pt1.

When the impingement height h2 is equal to the height h1, it is determined that the mist sprayed from the spraying device 481 has reached the spraying object OB while maintaining the straight state. In addition, the range where the impingement height h2 is equal to the height h1 shall include the case where the difference of the impingement height h2 and the height h1 is less than 20 mm.

It is sectional drawing which illustrates operation | movement in the primitive mode of the toilet seat apparatus which concerns on embodiment.

FIG. 14 is an enlarged view of the periphery of the front-side non-clean region 801F shown in FIG. 11.

As shown in FIG. 14, the front-side non-clean region 801F has an upper region 821 and a lower region 822. In addition, the upper region 821 has an R portion 823 and a mist guide portion 824.

The R portion 823 includes a top end of the front end side non-clean region 801F, and has a curved shape having a downward inclination toward the inside of the bowl portion 801. The mist guide part 824 is provided below the R part 823 and has a downward inclination toward the outer side of the bowl part 801. Alternatively, the mist guide portion 824 may extend in the vertical direction. The mist guide portion 824 is continuous with the R portion 823.

R portion 823 is located near rim upper surface 806. Therefore, when the spray direction Ds in which the spraying device 481 sprays mist is a direction in which many mists start in the R portion 823, the rim upper surface 806 tends to get wet. In this case, there exists a possibility that the mist which started on the rim upper surface 806 may fall out of the toilet bowl 800. As shown in FIG. In addition, since the R portion 823 has a downward inclination toward the inside of the bowl portion 801, mist reaching the R portion 823 is easily reflected by the R portion 823 and scattered toward the rim upper surface 806. . In particular, when the mist speed is increased so that the mist reaches the non-clean region 801B while maintaining the straight state, the mist tends to scatter.

In contrast, in the embodiment, the spraying direction Ds through which the spraying device 481 sprays mist is sprayed from the spraying device 481 and reaches the front end side non-cleaning area 801F while maintaining the straight state. Is set to start below the R portion 823. As a result, the amount of mist to be impinged on the rim upper surface 806 located above the R portion 823 can be reduced. Further, even when the speed of the mist is increased in order to maintain the straight state, it is possible to suppress the mist from flying toward the rim upper surface 806.

In addition, in the example shown in FIG. 14, the mist guide part 824 has the downward inclination toward the outer side of the bowl part 801, and guide | induces the mist which reached | attained the front end side non-cleaning area | region 801F downward. For example, the mist which reached the mist guide part 824 is reflected downward. As a result, even when the mist speed is increased so that the mist reaches the front end side non-cleaning region 801F while maintaining the straight state, the mist can be suppressed from flying toward the rim upper surface 806 side.

Moreover, the spray part (for example, disk 481b) which sprays mist is provided below a part of seating part 200. FIG. And the spraying direction Ds which the spraying device 481 sprays mist is set to the inclination direction toward the front end side non-cleaning area 801F. Thereby, the mist which reached the front end side non-cleaning area | region 801F becomes easy to scatter below. That is, the mist is likely to be reflected downward in the front end-side non-clean region 801F. Therefore, even if the mist speed is increased so that the mist reaches the front end side non-cleaning region 801F while maintaining the straight state, the mist can be suppressed from flying to the rim upper surface 806 side.

In addition, the spraying device 481 has a virtual line segment L2 (see FIG. 11) connecting the spraying unit (for example, the disk 481b) and the front side non-cleaning area 801F to the seating unit 200. It is arranged not to intersect. And the spraying direction Ds is set so that the mist which reaches the front end side non-cleaning area | region 801F may be sprayed along the line segment L2, maintaining a straight state. Thereby, mist can be started to the non-cleaning area | region 801B, suppressing that the seating part 200 gets wet by mist.

Further, in the pre-mist mode, the control device 405 has a lower area of the shear-side non-clean region 801F in which the average impinging amount per unit area of the mist directly impinging on the upper region 821 of the shear-side non-clean region 801F. The spraying device 481 is controlled to be smaller than the average amount of impingement per unit area of mist directly impinging on 822.

Specifically, for example, in the pre-mist mode, the control device 405 sprays 481 so that the particle size of the mist directly impinging on the lower region 822 is larger than the particle size of the mist directly impinging on the upper region 821. ). By increasing the particle diameter of the mist directly impinging on the lower region 822, the average amount of impingement per unit area of the mist directly impinging on the lower region 822 can be increased. In addition, by reducing the particle diameter of mist directly impinging on the upper region 821, the average amount of impingement per unit area of mist directly impinging on the lower region 822 can be reduced.

By increasing the average amount of impingement per unit area of mist directly impinging on the lower region 822, adhesion and seizure of dirt in the lower region 822 can be suppressed. On the other hand, by reducing the average amount of impingement per unit area of mist directly impinging on the upper region 821, the amount of mist impinging on the rim upper surface 806 or the seating portion 200 can be suppressed. For example, the mist which has reached the upper region 821 can be prevented from scattering on the rim upper surface 806 or the seating portion 200. As a result, mist falling on the rim upper surface 806 can be prevented from falling out of the toilet. In addition, the seating part 200 can be suppressed from being wet by the mist, and when the user sits on the seating part 200 or when the seating part 200 is rotated by hand, the user's buttocks and hands are held by the seating part ( It is possible to suppress contact with the mist started at 200).

15 (a) to 15 (c) are schematic diagrams for explaining a method for measuring the average amount of impingement per unit area of mist directly impinging on the upper region and the lower region of the non-clean region.

First, the first measurement point SU including the upper region 821 of the front side non-clean region 801F, and the second measurement point including the lower region 822 of the front side non-clean region 801F ( SL). The range of the left-right direction of the 1st measurement location SU and the 2nd measurement location SL is the range of width 100mm centering on the front-end | tip of the non-cleaning area | region 801B, respectively. In addition, the range of the up-down direction of the 1st measurement location SU is substantially the same as the range of the up-down direction of the upper area 821, and the range of the up-down direction of the 2nd measurement location SL is the up-down direction of the lower area 822. It is approximately equal to the range of.

After spraying mist to the front side non-clean area 801F, each of the first measurement point SU and the second measurement point SL was wiped with kimtool (manufactured by NIPPON PAPER CRECIA CO., LTD.) After the prescribed time. Serve Thereby, the mist which embarked on each of the 1st measurement location SU and the 2nd measurement location SL is made to absorb | suck in kimtool.

In addition, the prescribed time for spraying the mist is determined according to the spray flow rate Q (L / min) of the mist. When spray flow volume Q becomes Q <0.03L / min, prescribed time shall be 10 seconds. When the spray flow rate Q is 0.03 L / min ≤ Q <0.2 L / min, the specified time is 4 seconds. When the spray flow rate Q is Q? 0.2 L / min, the prescribed time is 2 seconds.

The difference between the weight of the kim towel which absorbed the mist which started in the 1st measurement point SU and the weight of the said kimto towel before the mist is started is the impingement amount of the mist which started in the 1st measurement point SU. The value obtained by dividing the impingement amount of the mist launched at the first measurement point SU by the area of the first measurement point SU is taken as the average impulse amount per unit area of the mist directly impinging on the upper region 821.

Similarly, the difference between the weight of the kim towel which absorbed the mist which started at the 2nd measurement point SL, and the weight of the said kim towel before the mist is started is the impinged amount of mist which started at the 2nd measurement point SL. The value obtained by dividing the impingement amount of the mist started at the second measurement point SL by the area of the second measurement point SL is taken as the average impulse amount per unit area of the mist directly impinging on the lower region 822.

In addition, instead of wiping each measurement point with a kimtowel, spraying may be performed in a state where a kimtowel is attached to each measurement point, and the mist may be absorbed into the kimtowel. For example, the kim towel which was originally folded into four nets is unfolded, and the kim towel which was not folded is cut into the shape according to each measurement location. Apply the cut kimto to each measurement point.

In the above example, the R portion 823 and the mist guide portion 824 are the upper region 821, and the lower region 822 is lower than the lower end of the mist guide portion 824. The boundary between the upper region 821 and the lower region 822 may be the center in the vertical direction of the front end side non-clean region 801F. That is, the upper region 821 is set as the upper region 821 than the center in the vertical direction of the front side non-clean region 801F, and the lower region 822 is lower than the center in the vertical direction of the front side non-clean region 801F. ) May be used.

16 (a) and 16 (b) are cross-sectional views illustrating the front end non-cleaning region of the toilet according to the embodiment.

As shown in FIG. 16A, the upper region 821 has an inclined surface (mist guide portion 824) inclined downward toward the outside of the bowl portion 801. As described above, the mist guide portion 824 (an inclined surface of the upper region 821) guides the mist downward.

On the other hand, as shown in FIG. 16 (b), the lower region 822 has an inclined surface inclined downward toward the inside of the bowl 801. As a result, the lower region 822 guides the mist reaching the lower region 822 upward. As a result, a part of the mist reached in the lower region 822 can be impregnated to the upper region 821, and the impingement amount (indirect impingement amount) in the upper region 821 can be increased. In addition, since the inclined surface of the upper region 821 is formed on the inclined surface of the lower region 822, the mist induced upward by the inclined surface of the lower region 822 exceeds the upper region 821 to the rim upper surface 806. The scattering is suppressed.

For example, the inclination angle θ1 of the upper region 821 is greater than the inclination angle θ2 of the lower region 822. The inclination angle θ1 is an angle between the vertical direction and the inclined surface (mist guide portion 824) of the upper region 821. The inclination angle θ2 is the angle between the vertical direction and the inclined surface of the lower region 822.

When the inclination angle θ1 is large, the mist reaching the upper region 821 can be induced more actively downward. In addition, when the inclination angle θ2 is small, the amount of mist induced upward by the lower region 822 can be suppressed. Since the inclination angle θ1 is greater than the inclination angle θ2, the mist induced to the upper region 821 by the lower region 822 is slowed down on the inclined surface of the upper region 821, so that it scatters to the upper surface of the rim 806. I never do that.

17 (a) and 17 (b) are cross-sectional views illustrating the operation of the toilet seat apparatus in the premist mode and the auto toilet lid opening mode.

The control device 405 automatically controls the toilet cover motor 512 when the detection sensor 402 is in the state of detecting the user from the state in which the detection sensor 402 is not detecting the user. It is possible to execute the auto toilet lid open mode in the open state.

For example, when the user is not in the bathroom, the toilet cover 300 is in a closed state. Thereafter, when the user enters the bathroom and the human body detecting sensor 403 detects the user's entrance, the control device 405 executes the automatic toilet cover opening mode. In addition, the control device 405 executes the primitive mode during the execution of the auto toilet lid opening mode.

For example, when the toilet seat opening mode is executed and the toilet cover 300 is opened as shown by arrow A6 of FIGS. 17A and 17B, the bowl part 801 and the bowl part 801 are opened. In the vicinity of the rise of the air flow (f1) occurs in accordance with the opening operation of the toilet cover (300). In the example of FIG. 17A, a part of the mist M sprayed by the mist mist mode rises upward from the bowl portion 801 in the rising air flow f1. In this case, the mist which has risen above the bowl portion 801 starts to the seating portion 200 or the rim upper surface 806.

On the other hand, in the example of FIG. 17 (b), the control apparatus 405 prevents the mist flying toward the front side non-clean region 801F from rising above the bowl portion 801 by the rising air flow f1. The particle size of the mist sprayed by the spraying device 481 is controlling. Specifically, the control apparatus 405 limits the rotational speed of the disk 481b of the spraying apparatus 481 so that the particle diameter of mist, for example, may not become small too much.

As a result, even when the raised air flow f1 is generated by the automatic toilet lid opening mode, the mist can be reached in the non-clean region 801B while preventing the mist from impinging on the rim upper surface 806 or the seating portion 200. have. Therefore, mist falling on the rim upper surface 806 can be prevented from falling out of the toilet bowl 800. In addition, the seating part 200 can be suppressed from being wet by the mist, and when the user sits on the seating part 200 or when the seating part 200 is rotated by hand, the user's buttocks and hands are held by the seating part ( It is possible to suppress contact with the mist started at 200).

In addition, the range in which the mist does not rise above the bowl portion 801 by the rising air flow f1 is such that not only does not all the mist rise above the bowl portion 801, but also does not cause discomfort to the user. The slight mist of may be included in the case where the mist rises above the bowl portion 801.

18 is a timing chart illustrating an operation in a primitive mode of the toilet seat apparatus according to the embodiment.

19 (a) and 19 (b) are plan views illustrating the operation in the primitive mode of the toilet seat apparatus according to the embodiment.

As shown in FIG. 18, the entrance of a user is detected by entrance detection means, such as a human body detection sensor 403, for example at the time T1. Then, the control device 405 starts the execution of the auto toilet lid opening mode and the premist mode. As a result, the toilet lid 300 in the closed state starts to open, and spraying of the mist into the bowl portion 801 is started. The opening operation of the toilet lid 300 can be continued from the time T1 to the time T4, and the toilet lid 300 is brought into the entire open state at the time T4.

FIG. 19B illustrates a range in which mist sprayed from the spraying device 481 starts from time T1 to time T2. In this way, in the time zone immediately after the start of the premist mode and the auto toilet lid opening mode, the control device 405 causes the mist to start in an area other than the non-clean area 801B of the bowl portion 801 (the cleaning area 801A). The spray device 481 is controlled.

FIG. 19A illustrates a range in which mist sprayed from the spraying device 481 starts between time T2 and time T3. Between the time T2 and the time T3, the control apparatus 405 controls the spraying apparatus 481 so that mist may start in the non-cleaning area 801B.

Thereafter, the control device 405 controls the spraying device 481 so that the mist starts to reach the cleaning area 801A between the time T3 and the time T4.

And until the time T5 after time T4, an auto toilet lid opening mode and a premist mode are complete | finished. For example, the user seats on the seating part 200 at time T5.

The size of the raised air flow f1 generated by the opening operation of the toilet cover 300 by the automatic toilet cover opening mode is immediately after the toilet cover 300 is opened from being closed (that is, when the toilet cover starts to open). Most likely to grow On the other hand, in embodiment, the control apparatus 405 starts spraying mist toward the front end side non-clean region 801F after starting execution of the automatic toilet lid opening mode. That is, as shown in FIG. 18, mist spraying to the front end side non-cleansing area | region 801F is started at time T2 after the time T1 in which the automatic toilet lid opening mode starts. Thereby, it can suppress more that mist rises above the bowl part 801 by the rising airflow f1.

In addition, the size of the rising air flow f1 generated by the opening operation of the toilet cover 300 in the automatic toilet cover opening mode is likely to increase when the toilet cover 300 is opened at a high speed. On the other hand, as shown in FIG. 18, the control apparatus 405 opens the toilet lid 300 in the 1st time slot (from time T1 to time T2) immediately after starting execution of an automatic toilet lid opening mode. The toilet cover motor 512 is controlled so that the speed becomes lower than the speed at which the toilet lid 300 is opened in the second time zone (from time T2 to time T3) after the first time zone. As a result, the rising air flow f1 can be reduced immediately after the start of the auto toilet lid opening mode. Therefore, it is possible to further suppress that the mist rises above the bowl portion 801 by the rising air flow f1 in the automatic toilet lid opening mode.

In addition, the control device 405 starts mist in a region other than the front-side non-clean region 801F in the third time period (from time T1 to time T2) immediately after the start of the execution of the auto toilet lid opening mode. Then, the spraying device 481 is controlled so that the mist starts the front end side non-cleaning region 801F in the fourth time zone (from the time T2 to the time T3) after the third time zone. Thereby, it can suppress more that mist rises above the bowl part 801 by the rising air flow f1 by the automatic toilet lid opening mode.

20 (a) and 20 (b) are sectional views illustrating the operation in the after-mist mode or the manual mist mode of the toilet seat apparatus according to the embodiment.

FIG. 20B is an enlarged view of the region R4 shown in FIG. 20A.

The broken arrow indicates the airflow formed by the blower 513 (also in FIGS. 24, 27, 28, and 30 to be described later). As shown in Fig. 20 (a), in the after-mist mode or the manual mist mode, the blower 513 blows forward and downward. At least a portion of the air sent from the blower 513 is directed upward in the toilet 800 (cleaning area 801A or non-cleaning area 801B). Thereby, the rising airflow U1 which winds up from the toilet seat 800 below the seat part 200 to the seat part 200 upward is formed.

For example, in the after mist mode or the manual mist mode, some mist is emitted from the spray apparatus 481 toward the non-clean region 801B. In addition, mist having a relatively large particle size starts at the cleaning region 801A. Mist with a relatively small particle diameter starts the rim upper surface 806, the seating part 200, the toilet seat cover 300, etc. by the rising airflow U1. Thereby, every corner of the toilet apparatus 10 including the non-cleaning area 801B, the rim upper surface 806, the seating part 200, the toilet seat cover 300, etc. can be disinfected.

Generally, tap water may contain scale components (for example, sodium, calcium, potassium, magnesium, etc.). In this case, the scale component is contained also in the mist of the germicidal water produced | generated from tap water. If the mist containing the scale component starts to evaporate after the toilet seat apparatus 100 or the like has evaporated, the scale may be precipitated at the portion where the mist has been undertaken, and contaminant generation may occur in a short time.

Thus, in one embodiment of the toilet seat apparatus 100, the after-mist mode sprays mist only in the toilet 800 as well as the mode of spraying mist on the toilet 800 and the seating part 200 (second mode). Has a first mode. In one after-mission mode, the control device 405 executes either one of the first mode and the second mode.

For example, in the first mode, the control device 405 stops the blower 513 so that the mist starts only in the toilet 800 (the washing area 801A and the non-cleaning area 801B), or the mist To control the particle diameter. In the first mode, it is possible to suppress the generation of bacteria and contamination in the toilet 800 by spraying mist of the germ-free water in the toilet 800. In addition, the scale component contained in the mist which started in the toilet 800 is wash | cleaned with the washing water which flows into the toilet 800. Therefore, the first mode of spraying mist only in the toilet 800 suppresses the generation of germs and contamination in the toilet 800, and visually stained soil contamination caused by the scale component is prevented from rim upper surface 806 and seating. It can suppress that it generate | occur | produces the part 200, the toilet seat cover 300, etc.

On the other hand, in the second mode, the control device 405 operates the blower 513 or controls the particle diameter of the mist so that the mist starts to enter the seating part 200 or the like as in the example of FIG. 20, for example. In the second mode, by spraying the mist of the germicidal water in the toilet 800 and the seating part 200, it is possible to suppress the occurrence of bacteria and contamination not only in the toilet seat 800 but also in the seating part 200.

In the after-mist mode, the control device 405 executes any one of the first mode and the second mode so that the frequency of attaching the mist to the seating unit 200 is lower than in the case where the second mode is executed every time. Can be. This makes it possible to lengthen the period until the adhered mist evaporates and the scale precipitated grows into visible soil contamination. Therefore, it is possible to suppress generation of visible soiling in a short time in a region where the washing water such as the seating portion 200, the toilet lid 300, and the rim upper surface 806 does not flow.

In addition, since the mist of the germicidal water is sprayed into the toilet 800 which is susceptible to contamination even when either of the first and second modes are executed in the after-mist mode, the frequency of cleaning by the user can be assured by executing the after-mist mode. Can be reduced. In addition, since the seating part 200 is a site where contamination is less likely to occur than in the toilet bowl 800, it is difficult to generate visible contamination even if the mist of the sterile water is not sprayed onto the seating part 200 every time.

In addition, in the range that the mist starts only in the toilet 800 in the first mode, not only the case where all the mists are launched in the toilet 800, but also a slight amount of mist which does not contribute to visually visible soil contamination. It may be included in the case of undertaking (200) or the like.

It is a flowchart which illustrates operation | movement in the after-mist mode of the toilet seat apparatus which concerns on embodiment.

The after-mist mode is not executed while the user is in the bathroom (step S101: No). When the user leaves the toilet and the detection sensor 402 detects the user and does not detect the user (step S101: Yes), the control device 405 includes the seating unit 200 and the toilet lid ( Close 300) to start the after-mist mode.

At this time, the control apparatus 405 automatically determines which of the first mode and the second mode of the after-mist mode is executed (step S102). This can reduce the burden on the user because the user does not have to select either the first mode or the second mode every time.

For example, in step S102, the control device 405 determines that the frequency of execution of the second mode is lower than the frequency of execution of the first mode. The low frequency of execution of the second mode makes it possible to reduce the amount of the mist containing the scale component attached to the seating portion 200. Therefore, it is possible to lengthen the time period until the scale is precipitated and grows into visible soil contamination.

More specifically, the control apparatus 405, for example, when a predetermined time has elapsed since the execution of the previous second mode or when the first mode has been executed a predetermined number of times after the execution of the previous second mode (step S102: Yes), the second mode is executed again (step S103), and the after-mist mode ends. As a result, since the second mode is executed regularly, generation of microorganisms and contamination by dirt can be suppressed while suppressing the occurrence of visible scale contamination in a short period of time.

On the other hand, the control device 405 does not execute the first mode a predetermined number of times after the execution of the previous second mode or after the execution of the previous second mode (step S102: No). ), The first mode is executed (step S104), and the after-mist mode ends. In addition, the predetermined time and the predetermined number of times in step S102 may be appropriately determined in consideration of the concentration of the scale component contained in the tap water and the spraying amount of the mist so as to prevent the contamination of the scale in a short time.

22 is a flowchart illustrating another operation in the after-mist mode of the toilet seat apparatus according to the embodiment.

In the after-mist mode, the control device 405 may determine which of the first mode and the second mode to execute based on the selection by the user's manual operation. For example, the manual operation unit 500 is provided with a switch or a button for the user to select which of the first mode and the second mode to execute.

The user performs an input operation of selecting one of the first mode and the second mode in the manual operation unit 500. The control apparatus 405 then receives information indicating which mode the user has selected (step S201).

If the detection sensor detects the user's leaving when the user selects the first mode on the manual operation unit 500 (step S202: Yes), the control device 405 executes the first mode (step S203). The mode ends. If the user's leaving is not detected, the after-mist mode is not executed (step S202: No).

If the detection sensor detects the user's leaving when the user selects the second mode on the manual operation unit 500 (step S204: Yes), the control device 405 executes the second mode (step S205). The mode ends. In addition, after the user's leaving is not detected, the after-mist mode is not executed (step S204: No).

In this way, in the after-mist mode, the control device 405 executes either the first mode or the second mode based on the user's selection in the manual operation unit 500. That is, the user can set in advance which one of the first mode and the second mode is executed by operating the manual operation unit 500.

For example, if the setting is not changed, the control device 405 executes one of the first mode and the second mode each time in the after-mist mode. The concentration of scale components in tap water varies from region to region. In a region where the concentration of the scale component is low, the time period until the visually feasible contamination due to the scale component occurs even if the second mode of spraying mist on the seating portion 200 is performed every time. In such an area, by executing the second mode in the after-mist mode, it is possible to reduce the frequency of cleaning by suppressing the generation of bacteria and contamination by dirt. On the other hand, in a region where the concentration of the scale component is high, when the second mode of spraying mist is also performed on the seating part 200, visually contaminated scale contamination due to the scale component is likely to occur in a short time. In such an area, it is possible to reduce the frequency of cleaning by not performing the second mode of spraying mist on the seating part 200. The frequency of cleaning can be made low in both the area | region where the density | concentration of the scale component contained in a tap water is high, and a low area | region by the user selecting which of a 1st mode and a 2nd mode is performed by the manual operation part 500. FIG.

In addition, the manual operation unit 500 may be provided with a switch or a button for selecting at least one of the frequency of execution of the first mode and the frequency of execution of the second mode. For example, when the second mode is executed when a predetermined time has elapsed from the execution of the previous second mode, the user can select the predetermined time on the manual operation unit 500. Further, for example, when the second mode is executed when the first mode is executed a predetermined number of times after the execution of the previous second mode, the user can select the predetermined number on the manual operation unit 500. The control device 405 executes at least one of the first mode and the second mode based on the user's selection (set frequency) on the manual operation unit 500. Thereby, the execution frequency of a 1st mode or the execution frequency of a 2nd mode can be selected so that the frequency of cleaning may become low according to the density | concentration of the scale component contained in the tap water of the area where the toilet seat apparatus 100 is used.

It is a flowchart which shows the other operation | movement in the after-mist mode of the toilet seat apparatus which concerns on embodiment.

In the example shown in FIG. 23, the after-mist mode is controlled so that mist of the germicidal water may be sprayed only in the toilet 800. As shown in FIG. In other words, the above-described first mode is executed every time. 23 also illustrates the operation in the passive mist mode. In this example, the manual mist mode sprays the mist of the germicidal water into the toilet 800 and the seating portion 200 similarly to the examples described with reference to FIGS. 9 and 20.

When the user leaves the toilet and the detection sensor 402 detects the user and does not detect the user (step S301: Yes), the control device 405 starts the after-mist mode. The mist of the germicidal water is sprayed only in the toilet bowl 800 (step S302), and the after-mist mode is complete | finished. In the after-mist mode, by not spraying the sanitizing water on the seating part 200 or the like, it is possible to suppress generation of visually contaminated scale contamination due to the scale component in a short time.

If the user does not leave the toilet (step S301: No), when the user operates the manual operation unit 500 (step S303: Yes), the control device 405 starts the manual mist mode. Mist of germicidal water is sprayed on the toilet bowl 800 and the seating part 200 (step S304), and manual mist mode is complete | finished. In addition, when the user does not operate the manual operation part 500 (step S303: No), the manual mist mode is not performed.

Since the manual mist mode is a mode in which the user wipes the paper after misting, the frequency of the manual mist mode tends to be lower than that of the after mist mode. Therefore, as in the example shown in FIG. 23, mist is sprayed only in the toilet 800 in the after-mist mode, and mist is sprayed into the toilet 800 and the seating part 200 in the manual mist mode. It is possible to reduce the frequency of the mist attached to the 200). Thereby, it is possible to lengthen the period until the scale component precipitated by evaporation of the adhered mist grows into visible soil contamination. Therefore, it is possible to suppress generation of visible soiling in a short time in a region where the washing water such as the seating unit 200 does not flow.

24 (a) and 24 (b) are cross-sectional views illustrating the operation in the premist mode and the after-mist mode of the toilet seat apparatus according to the embodiment.

As shown in Fig. 24A, the mist mode sprays mist of tap water or germicidal water into the washing area 801A and the non-cleaning area 801B, and tap water or germicidal water is washed area 801A and non-cleaning. The water droplet WD1 or the water film WF1 is formed in the region 801B. For example, the control device 405 keeps the mist started by reducing the particle size of the mist or controlling the amount of mist to be started in the pre-mist mode. In addition, it is not necessary for all the mists in the mist to be started to remain, and it is sufficient to stay so that dirt can be prevented from adhering or sticking to the cleaning region 801A and the non-cleaning region 801B.

After that, when the user leaves the toilet, the after-mist mode is executed. As shown in FIG. 24 (b), in the after-mist mode, the mist of germicidal water is impregnated in the water droplet WD1 or the water film WF1 formed in the non-clean region 801B. As a result, the after-mist mode washes the water droplet WD1 or the water film WF1 by increasing the volume of the water droplet WD1 or the water film WF1. That is, as the volume increases and the weight increases, the water droplet WD1 or the water film WF1 formed in the non-clean region 801B flows down to the cleaning region 801A. In addition, in the pre-mist mode, even when all the mist in the mist WD1 formed in the non-cleaning region 801B or the water film WF1 has not been washed out, most of the mist is washed out to prevent the occurrence of visible soil contamination. Can be delayed.

The mist sprayed in the premist mode stays in the cleaning area 801A and the non-cleaning area 801B, and for example, the water droplet WD1 or the water film WF1 does not flow until after the after-mist mode is executed. As a result, it is possible to more suppress the adhesion and sedimentation of the dirt than in the case where only the bowl portion 801 is wet. In the after-mist mode, mist of the bactericidal water sprayed from the spraying device 481 impinges on the non-cleaning region 801B. Thereby, generation | occurrence | production of the microorganisms and contamination by the dirt which was not wash | cleaned by washing water can be suppressed.

In addition, when the water droplet WD1 or water film WF1 formed by the primitive mode remains attached to the non-clean region 801B, the scale is precipitated by evaporation of the water droplet WD1 or water film WF1. Scalding contamination may occur in the cleaning area 801B. On the other hand, the water droplet WD1 or the water film WF1 formed in the non-clean region 801B by the after-mist mode is washed away to prevent the water droplet WD1 or the water film WF1 from remaining in the non-clean region 801B. can do. As a result, generation of scale contamination can be suppressed. Therefore, it is possible to suppress the generation of visible soil contamination in the non-clean area 801B in a short period of time while suppressing the occurrence of bacteria and contamination in a wide range of the toilet 800 including the non-clean area 801B. have.

25 (a) and 25 (b) are cross-sectional views illustrating another operation in the premist mode of the toilet seat apparatus according to the embodiment.

In this example, the primitive mode has the 1st process shown to FIG. 25 (a), and the 2nd process shown to FIG. 25 (b).

As shown in Fig. 25A, the first process starts mist in the non-clean region 801B, and forms the water droplet WD1 or the water film WF1 in the non-clean region 801B. In the first step, the mist may also be impregnated in the washing region 801A to form a water drop or a water film.

As shown in FIG. 25 (b), the second process starts mist in the water droplet WD1 or the water film WF1 formed in the non-clean region 801B in the first process. Thereby, a 2nd process wash | cleans the water droplet WD1 or the water film WF1 by increasing the volume of the water droplet WD1 or the water film WF1. That is, as the volume increases and the weight increases, the water droplet WD1 or the water film WF1 formed in the non-clean region 801B flows down to the cleaning region 801A. In the premist mode, the first process and the second process may be continuous in time.

For example, when the detection sensor 402 detects a user by a filth chamber or the like and the first process of the primitive mode is executed, the water droplet WD1 formed in the non-clean region 801B by executing the second process or The water film WF1 falls.

By washing the water droplet WD1 or the water film WF1 formed in the non-clean region 801B by the first process by the second process, the water droplet WD1 or the water film WF1 remains in the non-clean region 801B. It can be suppressed. As a result, generation of scale contamination can be suppressed. Therefore, it is possible to suppress the generation of visible soil contamination in the non-clean area 801B in a short period of time while suppressing the occurrence of bacteria and contamination in a wide range of the toilet 800 including the non-clean area 801B. have.

In addition, if the mist is sprayed so that the mist started in the pre-mist mode flows immediately, there is a possibility that the mist may splash in the bowl portion 801 and splash out of the toilet 800 because the mist has a large particle size or flow rate. In contrast, in this example, the water droplet WD1 or the water film is formed by increasing the volume of the water droplet WD1 or the water film WF1 by the second process after forming the water droplet WD1 or the water film WF1 by the first process. (WF1) is falling. As a result, mist can be prevented from scattering out of the toilet.

26 (a) and 26 (b) are plan views illustrating the toilet and the toilet seat according to the embodiment.

FIG.26 (a) has shown the back surface 204 side of the seating part 200. FIG. The toilet seat leg 210 is provided in the back surface 204 of the seating part 200. The toilet seat leg 210 is provided so as to protrude from the rear surface 204 and contacts the rim upper surface 806 of the toilet bowl 800 in a state where the seat 200 is closed. In this example, a total of four toilet seat legs 210 are provided, but the number and shape of the toilet seat legs 210 are arbitrary.

As shown in FIG.26 (b), the rim upper surface 806 of the toilet bowl 800 has the area | region 810 which the toilet seat leg 210 contacts in the state in which the seating part 200 was closed.

In the mist mode (for example, after mist mode or manual mist mode) in which mist of the germicidal water is sprayed on the rim upper surface 806 and the seating portion 200, the toilet bowl 800 and the toilet lid 300 are opened. There is a fear that mist may scatter on the outside of the toilet seat apparatus 100. Therefore, in order to suppress scattering of mist, it is preferable that the toilet seat cover 300 and the seating part 200 are closed. On the other hand, in the mist mode in which the mist of the germicidal water is sprayed on the rim upper surface 806 and the seating portion 200, the region 810 of the rim upper surface 806 when the toilet lid 300 and the seating portion 200 are closed. Since the toilet seat leg 210 and the toilet seat 210 are in contact with each other, mist cannot be launched into the region 810 and the toilet seat leg 210. In addition, since the toilet lid 300 and the seating portion 200 are closed, the upper rim 806 and the seating portion 200 are close to each other, so that the outer circumferential portion 204e or the rim of the rear surface 204 of the seating portion 200 is closed. Mist hardly reaches the outer peripheral portion 806e of the upper surface 806.

Therefore, in one embodiment of the toilet seat apparatus 100, the after mist mode or the manual mist mode has the 1st process and the 2nd process demonstrated below.

27 (a) and 27 (b) are cross-sectional views illustrating the operation in the after-mist mode or the manual mist mode of the toilet seat apparatus according to the embodiment.

Fig. 27A shows the first step and Fig. 27B shows the second step. As shown in FIG. 27 (a), in the first step, the control device 405 controls the toilet seat motor 511 and the toilet seat cover motor 512 to cover the seating unit 200 and the toilet seat cover 300. Set to the closed state (completely closed state). In the state where the toilet lid 300 is closed, the first process sprays mist of the germicidal water onto the rim upper surface 806 and the seating portion 200. In the first step, since the toilet lid 300 is in a closed state, a large amount of mist is applied to the rim upper surface 806 or the seating portion 200 while preventing mist from scattering outside the toilet 800 and the toilet seat apparatus 100. Can be sprayed.

As shown in FIG. 27 (b), in the second step, the control device 405 controls the toilet seat motor 511 and the toilet seat cover motor 512 to control the seating unit 200 and the toilet seat cover 300. Keep it open. In the state in which the seating part 200 and the toilet seat cover 300 are open, the 2nd process sprays mist of the germicidal water to the rim upper surface 806 and the seating part 200. Thereby, the 2nd process sprays mist of the germicidal water in the area | region 810 which the toilet seat leg part 210 of the rim upper surface 806 contacts. In the second step, since the seating portion 200 is in an open state, mist can also be launched into the seat leg portion 210 and the region 810 of the rim upper surface 806. In addition, mist is likely to be impinged on the outer circumferential portion 806e of the rim upper surface 806 and the outer circumferential portion 204e of the seating portion 200.

The control apparatus 405 executes a 2nd process, for example after performing a 1st process in one after-mist mode and a manual mist mode. Alternatively, the first step may be performed after the second step. The area 810 in which the toilet seat leg 210 of the rim upper surface 806 is in contact with each other while the mist is scattered to the outside of the toilet 800 and the toilet seat apparatus 100 by the first and second processes described above. By launching a lot of mist in a wide range, including, it is possible to suppress the occurrence of bacteria and contamination.

In addition, in the 2nd process of an after mist mode or a manual mist mode, the range in which the seating part 200 and the toilet seat cover 300 are opened shall include not only a fully open state but also a semi-open state. The fully open state is a state in which the degree of opening is maximum in normal use. The half-open state is a state in which the opening degree is smaller than that of the full open state. That is, the half-open state is a state between a fully open state and a fully closed state, and the opening degree is not limited to being half of the fully open state.

In the second step, when the seating part 200 is in the fully open state, since the toilet seat leg 210 is far from the rim upper surface 806, it becomes difficult to launch a mist into the toilet seat leg 210. On the other hand, in the example shown to FIG. 27 (b), the control apparatus 405 controls the toilet seat motor 511 so that the seating part 200 may be half-opened in a 2nd process. For this reason, the distance between the toilet seat leg 210 and the rim upper surface 806 can be shortened compared with the case where the seating part 200 is in a fully open state. Thereby, the mist of the germicidal water can be started also in the toilet seat leg part 210 which is hard to reach the mist of the germicidal water in a 1st process in a 2nd process.

For example, in the control apparatus 405, the total amount (ml) of mist of the germicidal water sprayed to the rim upper surface 806 side in the first process is sprayed to the rim upper surface 806 side in the second process. The spraying device 481 is controlled to be larger than the total amount of mist of water (ml). For example, the total amount of the mist of the germicidal water which impinges on the rim upper surface 806 in a 1st process is larger than the total amount of the mist of the germicidal water which impinges on the rim upper surface 806 in a 2nd process. In the first step, a large number of germicidal water mists start on the rim upper surface 806, whereby the occurrence of bacteria and contamination on the rim upper surface 806 can be further suppressed. At this time, since the toilet lid 300 is closed in the first step, even if a large amount of mist is sprayed, the mist may scatter out of the toilet bowl 800 and the toilet seat apparatus 100. On the other hand, in the 2nd process with the toilet seat 300 open with the seating part 200, mist is easy to fly out of the toilet bowl 800 and the toilet seat apparatus 100 compared with a 1st process. Therefore, in a 2nd process, by launching a comparatively small amount of mist on the rim upper surface 806, it can suppress that mist spreads to the exterior of the toilet bowl 800 and the toilet seat apparatus 100. As shown in FIG.

Specifically, for example, in the control apparatus 405, the time for spraying the mist of the germicidal water on the rim upper surface 806 side in the first process is the mist of the germicidal water on the rim upper surface 806 side in the second process. The spraying device 481 is controlled to be longer than the time for spraying. That is, for example, the time when the first process is executed is longer than the time when the second process is executed. Thereby, the total amount of mist sprayed to the rim upper surface 806 side in a 1st process can be made larger than the total amount of mist sprayed to the rim upper surface 806 side in a 2nd process.

28 (a) and 28 (b) are sectional views illustrating the operation in the second step of the after-mist mode or the manual mist mode of the toilet seat apparatus according to the embodiment.

In the second step of the after-mist mode or the manual mist mode, the control device 405 sprays the toilet seat motor 511 and the toilet cover motor 512 in the state of spraying the mist of the germicidal water on the rim upper surface 806 side. At least one of the seating unit 200 and the toilet seat cover 300 may be moved by controlling. FIG. 28A shows the state in which the seating unit 200 is moved in the opening direction in the second step. As shown by arrow A7, when seating part 200 is rotated from below to upward, airflow f2 (rising airflow) is generated in the vicinity of rim upper surface 806. The mist of the germicidal water can start the mist of the germicidal water in a wider range of the rim upper surface 806 by riding the air stream f2.

In addition, FIG. 28 (b) shows a state in which the seating unit 200 is moved in the closing direction in the second step. As shown by the arrow A8, when the seating part 200 is rotated from the upper side to the lower side, the air flow f3 is generated in the vicinity of the rim upper surface 806. As a result, the mist in the vicinity of the rim upper surface 806 diffuses, and the mist of the germicidal water can be launched in a wider range of the rim upper surface 806.

In the example shown to FIG. 28 (a) and FIG. 28 (b), although the control apparatus 405 is moving the seating part 200, you may similarly move the toilet seat 300. As shown in FIG. In the second step, the control device 405 may stop one of the seating part 200 and the toilet seat cover 300 to move the other, or may move both.

29 is a plan view illustrating the toilet device according to the embodiment.

In FIG. 29, the toilet 800 is shown with a solid line. In addition, the casing 400 of the toilet seat apparatus 100 mounted on the upper surface of the toilet bowl 800, ie, the rim upper surface 806, is shown with the broken line.

The casing 400 (body part) of the toilet seat apparatus 100 is mounted in the rear part of the rim upper surface 806. That is, the rim upper surface 806 has a non-loading portion 806f in which the casing 400 is not loaded, and a loading part 806r in which the casing 400 is loaded. The loading part 806r is located behind the non-loading part 806f. The loading part 806r means the part of the rim upper surface 806 which overlaps with the casing 400 in a perpendicular direction, and the loading part 806r does not need to be in contact with the casing 400.

In addition, a packing 490 is provided between the casing 400 and the mounting portion 806r of the rim upper surface 806. The packing 490 is arrange | positioned at the front part of the loading part 806r according to the shape of the casing 400. As shown in FIG. This can prevent the washing water, the mist, the dirt, and the like from entering the rear side of the packing 490.

On the front side of the packing 490, a gap SP is formed between the mounting portion 806r and the casing 400. For example, in the after-mist mode or the manual mist mode, when the mist of germicidal water is sprayed not only in the bowl portion 801 but also on the rim upper surface 806, the mist of the germicidal water enters the gap SP. have. Since the gap SP is a difficult part for the user to see, the mist that has started the loading part 806r entering the gap SP unintentionally becomes large drops (WD2) or water film (WF2) and falls out of the toilet (800). May occur.

Therefore, in the after-mist mode or the manual mist mode, the spraying device 481 has an average amount of impingement per unit area of the number of sterilizations that starts the loading part 806r. Eject the germicidal water so that there is more. It is preferable that the spraying device 481 starts the germicidal water in the non-loading part 806f and does not start the germicidal water in the loading part 806r.

The generation of germs and contamination in the non-loading portion 806f can be suppressed by launching more sterilizing water to the non-loading portion 806f than the loading portion 806r. The non-loading portion 806f is a portion that is easy to dry because air is less likely to stay than the loading portion 806r, and is a portion that is easy to be wiped by the user. Therefore, even if the bacteriostatic water starts at the non-loading portion 806f of the upper surface 806 of the rim, the possibility that the bactericidal water aggregates at the non-loading portion 806f unintentionally becomes a large drop or water film, and thus the possibility of falling out of the toilet bowl 800 is low. . In addition, since the number of germs to be launched to the loading portion 806r is relatively small, it is possible to prevent the germ counts from being aggregated in the loading portion 806r unintentionally to form a large water drop or water film and falling out of the toilet bowl 800. Therefore, when the mist of germicidal water is sprayed on the rim upper surface 806 of the toilet 800, the leak out of the toilet 800 can be suppressed.

In addition, the average amount of impingement per unit area can be measured as follows.

First, after the execution of the after-mist mode or the manual mist mode, the mist which has started to the non-loading part 806f is wiped off with kim towel. By dividing the weight of the kim towel before wiping the mist and the area of the non-loading portion 806f wiping off the difference in the weight after wiping the mist, the average amount of impingement per unit area of the germicidal water undertaken at the non-loading portion 806f Is calculated.

Similarly, after the execution of the after-mist mode or the manual mist mode, the mist that has started to the loading portion 806r on the front side of the packing 490 is wiped off with a kim towel. By dividing the weight of the kim towel before wiping the mist and the area of the loading section 806 r wiping off the difference between the weights after wiping the mist, the average amount of impingement per unit area of the germicidal water launched on the loading section 806 r is calculated. .

It is sectional drawing which illustrates operation | movement in the after mist mode or the manual mist mode of the toilet seat apparatus which concerns on embodiment.

31 (a) and 31 (b) are perspective views illustrating the operation in the after-mist mode or the manual mist mode of the toilet seat apparatus according to the embodiment.

In this example, the spraying device 481 has the first water jetting part 51 and the second water jetting part 52. For example, a nozzle capable of ejecting (spraying) tap water or sterilizing water is used for the first water jetting part 51. For example, the above-described disk 481b is used for the second jetting portion 52.

The flow path 113 which guides water to the spraying device 481 is branched into the flow path which supplies water to the 1st water jetting part 51, and the flow path which supplies water to the 2nd water jetting part 52. As shown in FIG. The water supply to each water jetting unit is controlled by the control device 405. The 1st water jetting part 51 and the 2nd water jetting part 52 blow off (spray) the germicidal water simultaneously, for example.

FIG. 31A illustrates the operation of the second jetting unit 52 in the after mist mode or the manual mist mode. The second water jetting unit 52 starts the germicidal water at the non-loading portion 806f of the rim upper surface 806. In addition, the second water jetting unit 52 impinges the germicidal water on the front side than the second water jetting unit 52 in the bowl 801.

For example, the second water jetting unit 52 sprays mist of the germicidal water forward and downward. Some of the sprayed mist rises above the rim upper surface 806 in the upward air flow U1 formed by the blower 513. Thereby, mist of the germicidal water starts in the non-loading part 806f, the seating part 200, and the toilet seat cover 300. As shown in FIG.

FIG. 31B illustrates the operation of the first water jetting unit 51 in the after mist mode or the manual mist mode. The first water jetting unit 51 ejects (sprays) the germicidal water backwards and downwards, and starts the germicidal water on the rear side (the loading part 806r side) than the first jetting unit 51 in the bowl part 801. Let's do it.

The spray device 481 is provided inside or below the casing 400. In addition, the germicidal water sprayed from the spraying device 481 gradually falls by its own weight. Therefore, it is preferable to spray the germicidal water from a high position in order to start the germicidal water in the non-loading part 806f. Therefore, as shown in FIG. 30, the 2nd water jetting part 52 is arrange | positioned above the 1st water jetting part 51 (nozzle water jetting port). Thereby, the germicidal water can be settled to the non-loading part 806f more reliably. On the other hand, in order to suppress the start of the germicidal water in the loading part 806r, it is preferable to eject (spray) the germicidal water from a low position. Since the 1st water jetting part 51 (nozzle water jetting port) is arrange | positioned below the 2nd water jetting part 52, it can suppress more that the germicidal water impinges on the loading part 806r.

In addition, the second water jetting unit 52 is desired to be clean in order to start the sterilizing water on the non-loading portion 806f of the upper surface 806 where the user may come into contact with. Thus, the second water jetting portion 52 is disposed inside the casing 400. In addition, the second jetting portion 52 (disc 481b) is located above the rim upper surface 806. As a result, dirt can be prevented from adhering to the second water jetting part 52, thereby ensuring cleanliness of the second water jetting part 52.

On the other hand, the first water jetting unit 51 has a problem of cleanliness compared to the second water jetting unit 52 in order to start the sterilization water on the loading part 806r side in the bowl part 801 where the user is unlikely to contact. It's hard to be. Therefore, the 1st water jetting part 51 is arrange | positioned so that it may protrude below the casing 400. FIG. For example, the first water jetting portion 51 (nozzle jetting port) is located below the rim upper surface 806. Thereby, the 1st water jetting part 51 can be arrange | positioned in a low position, and it can suppress more that a bactericidal water starts to the loading part 806r.

In addition, the spraying apparatus 481 (the 2nd water jetting part 52 sees an upper surface, and raises at least one part of the germicidal water which sprays on the loading part 806r side (rear side) rather than the spraying apparatus 481 with an upward airflow U1 ) Is sprayed onto the non-loading portion 806f (front side) than the spraying device 481 as seen from above. At least a part of the germicidal water is formed to a size that rides the rising air stream U1.

Specifically, the spraying apparatus 481 makes the germicidal water sprayed to the loading part 806r side rather than the spraying apparatus 481 into the shower shape, the film shape, or the mist shape of a 1st particle diameter. In addition, the spraying apparatus 481 makes the germicidal water ejected to the non-loading part 806f side rather than the spraying apparatus 481 into the mist shape of a 2nd particle size smaller than a 1st particle diameter.

As a result, the germicidal water ejected from the spraying device 481 to the non-loading portion 806f side is more likely to catch an ascending air stream than the germicidal water sprayed to the loading portion 806r side, and the germicidal water is more contained in the non-loading portion 806f. Can be launched. On the contrary, the germicidal water ejected from the spraying device 481 to the loading part 806r side is less likely to catch an ascending air stream than the germicidal water ejected to the non-loading part 806f side, thereby suppressing the start of the germicidal water at the loading part 806r. can do.

In addition, the average value or median value of the particle size distribution of mist can be used for the comparison of the magnitude | size of a 1st particle size and a 2nd particle size. In addition, the shower shape and the film shape are the shape of water larger than the fine particles of mist. The self-weight of the shower-like and membrane-shaped germicidal water is larger than the self-weight of the particles of the mist of the first particle diameter. The shower-like germicidal water may be a thread shape or a large particle shape. The shape and size of the germicidal water sprayed on the stacking portion 806r side can be adjusted by, for example, the shape of the water jetting port of the first water jetting portion 51.

In FIG. 30 and FIG. 31, the case where two water jetting parts were provided was demonstrated. However, the number of jetting parts may be one or three or more. By suitably changing the spraying direction, spraying range, and particle size of the mist, it is possible to suppress the starting of the germ-free water in the loading portion 806r while launching a large number of the germ-free water in the non-loading portion 806f.

32 is a flowchart illustrating the operation in the manual mist mode of the toilet seat apparatus according to the embodiment.

When the user operates the manual operation unit 500, the control device 405 can execute the manual mist mode based on the operation information of the manual operation unit 500. Here, when the operation of the manual operation part 500 is performed continuously for a short time, and the manual mist mode is performed continuously for a short time, there exists a possibility that the seating part 200 may become excessively wet. As a result, the user who is in contact with the mist launched into the seating unit 200 may feel uncomfortable, or the mist may fall out of the toilet 800.

So, in the example shown in FIG. 32, the control apparatus 405 has a continuous passive mist prohibition mode. In the continuous manual mist prohibition mode, when the manual operation unit 500 is operated again within a predetermined time after the execution of the manual mist mode (before the predetermined time elapses from the end of the manual mist mode), the predetermined time from the end of the manual mist mode is changed. Prohibit manual mist mode again until it has elapsed. In addition, the continuous manual mist prohibition mode prohibits the execution of the manual mist mode again until a predetermined time elapses from the end of the manual mist mode even when the manual operation unit 500 is operated again during the execution of the manual mist mode.

For example, as shown in FIG. 32, when a user operates the manual operation part 500, and inputs the start of a manual mist mode (step S401: Yes), the control apparatus 405 predetermined | prescribes from the end of the last manual mist mode. It is determined whether time has elapsed (step S402). If the predetermined time has elapsed (step S402: Yes), the control device 405 executes the manual mist mode (step S403). On the other hand, if the predetermined time has not elapsed during the execution of the manual mist mode or the end of the last manual mist mode (step S402: No), and the wiping operation described later is not detected (step S404: No), The control device 405 executes the continuous manual mist prohibition mode. In other words, manual mist mode is not executed.

In this way, even if the manual operation unit 500 is operated during the execution of the manual mist mode or within a predetermined time after the execution, the manual mist mode is not executed again by the continuous manual mist prohibition mode. Thereby, even if the manual operation which sprays mist in a short time is performed continuously, it can suppress that too much mist is imposed on the seating part 200. Many mists can be launched to the seating unit 200, and the user can feel uncomfortable, and mists that have started to the seating unit 200 can be prevented from falling out of the toilet bowl 800.

In addition, the predetermined time in step S402 is set to the time which the mist which started even if manual mist mode is again performed, and even if mist starts in the seating part 200 does not fall out of the toilet bowl 800, for example. . The predetermined time is appropriately determined according to the amount of mist sprayed in the manual mist mode, for example, 10 seconds or more and 5 minutes or less. The predetermined time may be a time at which the mist started on the seating unit 200 evaporates in the last manual mist mode.

The user may remove germs or contamination adhered to the seating part 200 by wiping the mist that has started on the seating part 200 by the manual mist mode using a toilet paper or the like. If contamination remains on the seating unit 200 after the user wipes out almost all of the mist launched on the seating unit 200, the user may want to execute the manual mist mode again and wipe off the remaining contamination. In this case, waiting for a predetermined time is inconvenient for the user.

Thus, the control device 405 has a manual mist release mode which releases the continuous manual mist prohibition mode before the predetermined time elapses from the end of the manual mist mode, and makes the manual mist mode executable again. As a result, the manual mist mode can be executed again even if a predetermined time has not elapsed from the previous manual mist mode, and the convenience of use can be improved.

The toilet seat apparatus 100 has a wiping operation | movement detection means which detects that a user performed the wiping operation | movement with respect to the seating part 200. FIG. The control device 405 executes the manual mist release mode based on the detection information of the wiping operation detection means.

As shown in FIG. 32, when the user has detected that the wiping operation has been performed by the wiping operation detecting means (step S404: Yes), the manual mist releasing mode is executed. That is, the manual mist mode can be executed again, and the manual mist mode is executed (step S403).

As the wiping operation detection means, for example, the seating detection sensor 404 can be used. The control device 405 estimates the presence or absence of the wiping operation based on the detection information of the seating detection sensor 404. By using the seat detection sensor 404, the wiping operation | movement of a seat part by a user can be detected more reliably. For example, when the seating detection sensor 404 is a sensor which can detect the load applied to the seating part 200, the user wipes | moves based on the magnitude of the load applied to the seating part 200, or the time to which the load was applied. It can detect that it did. For example, when the seating detection sensor 404 is a sensor which can acquire the distance to a human body, it can detect that the user performed the wiping operation | movement based on the change of distance.

In addition, even though the user has operated the manual operation unit 500 to execute the manual mist mode, if the mist is not sprayed because the manual mist mode is not executed by the continuous manual mist prohibition mode, the user may determine that the toilet seat apparatus 100 There is a risk of misunderstanding. Therefore, when the wiping operation of the user is not detected (step S404: No), the control device 405 notifies the notification means that the continuous manual mist prohibition mode has been executed (step S405). As a result, misunderstanding of the user can be prevented. As the notification means, any means capable of notification by sound or light can be used. For example, a speaker, an LED, a liquid crystal display, or the like can be appropriately installed in the manual operation unit 500 or the casing 400 as the notification means.

In addition, the toilet seat apparatus 100 has an operation part (for example, the manual operation part 500) which inputs that the user performed the wiping operation | movement with respect to the seating part 200. As shown in FIG. The control device 405 executes the manual mist release mode on the basis of the input information input to the operation unit. For example, when a user operates a switch or the like of the manual operation unit 500, input information (signal) is sent to the control device 405, and the control device 405 executes the manual mist canceling mode when the input information is received. (Step S406: Yes). As a result, the manual mist mode can be executed again, and the manual mist mode is executed (step S403). By using such an operation part, the wiping operation | movement of the seating part 200 by a user can be detected more reliably, and the convenience of use can be improved. In addition, a user may operate the said operation part as needed, without performing a wiping operation | movement.

When the user does not operate the operation unit which inputs that the user has performed the wiping operation on the seating unit 200 (step S406: No), execution of the manual mist mode is prohibited until a predetermined time elapses from the end of the manual mist mode. State is maintained.

33 is a flowchart illustrating another operation in the manual mist mode of the toilet seat apparatus according to the embodiment.

In the example shown in FIG. 33, the control apparatus 405 has two types of manual mist modes, a 1st manual mist mode and a 2nd manual mist mode. The total amount of mist of the germicidal water sprayed in a 2nd manual mist mode is less than the total amount of mist of the germicidal water sprayed in a 1st manual mist mode. For example, the spraying time of the second manual mist mode is shorter than the spraying time of the first manual mist mode.

The 1st manual mist mode is an operation mode which sprays the mist of sterile water to the seating part 200 by controlling the spraying device 481 when a user operates the manual operation part 500. FIG.

On the other hand, in the second manual mist mode, when the manual operation unit 500 is operated again within a predetermined time after the execution of the first manual mist mode (before the predetermined time elapses from the end of the first manual mist mode), the spray device ( 481) is sprayed and mist of the germicidal water is sprayed on the seating part 200. FIG. In the second manual mist mode, even when the manual operation unit 500 is operated again during the execution of the first manual mist mode, the spray device 481 is controlled to spray mist of the germ-free water to the seating unit 200.

In other words, it is prohibited to execute the first manual mist mode again until a predetermined time has elapsed from the end of the first manual mist mode, and the second manual mist mode is executed instead.

For example, as shown in FIG. 33, when a user operates the manual operation part 500 and inputs start of a manual mist mode (step S501: Yes), the control apparatus 405 ends the last 1st manual mist mode. From step S502, it is determined whether or not the predetermined time has elapsed. If the predetermined time has elapsed (step S502: Yes), the control device 405 executes the first manual mist mode (step S503). On the other hand, if the predetermined time has not elapsed during execution of the first manual mist mode or the end of the previous first manual mist mode (step S502: No), and no wiping operation is detected (step S504: No) The control device 405 executes the second manual mist mode.

 In this way, when the manual operation unit 500 is operated during the execution of the first manual mist mode or within a predetermined time after the execution, the second manual mist mode in which the spray amount of mist is smaller than that of the first manual mist mode is executed. Thereby, even if the manual operation which sprays mist is performed continuously, it can suppress that too much mist enters the seating part 200. Many mists can be launched to the seating unit 200, and the user can feel uncomfortable, and mists that have started to the seating unit 200 can be prevented from falling out of the toilet bowl 800.

In addition, the predetermined time in step S502 is such that, for example, even when the first manual mist mode is executed again and the mist starts to sit in the seating unit 200, the mist that is undertaken does not flow out of the toilet 800. Is set. Predetermined time is suitably determined according to the quantity of mist sprayed, and is 10 second or more and 5 minutes or less, for example. The predetermined time may be a time at which the mist started on the seating unit 200 evaporates in the first passive mist mode.

When the user wants to further wipe off the dirt remaining in the seating part 200 after the execution of the first manual mist mode, when the mist amount of the mist is small by the second manual mist mode, it may be inconvenient to wipe off the dirt.

Thus, the control device 405 has a manual mist release mode that makes the first manual mist mode executable again before a predetermined time elapses from the end of the first manual mist mode. Thereby, even if it does not pass predetermined time from the last 1st manual mist mode, execution of a 1st manual mist mode is possible again, and the convenience of use can be improved.

As shown in FIG. 33, when it is detected that the user performed the wiping operation by the wiping operation detecting means (step S504: Yes), the manual mist releasing mode is executed. That is, execution of a 1st manual mist mode is possible again, and a 1st manual mist mode is performed (step S503).

In addition, when the user operates the manual operation unit 500, the first manual mist mode is not executed and the second manual mist mode is executed, and when the mist amount of the mist is small, the user may mistake that the toilet seat apparatus 100 has failed. There is concern. Therefore, when the wiping operation of the user is not detected (step S504: No), the control device 405 notifies by the notifying means that the second manual mist mode has been executed (step S505). As a result, misunderstanding of the user can be prevented.

In addition, when an operation unit for inputting that a user performs a wiping operation on the seating unit 200 is operated, input information (signal) is sent to the control device 405, and the control device 405 receives the input information. The manual mist canceling mode is executed (step S506: Yes). Thereby, execution of a 1st manual mist mode is possible again, and a 1st manual mist mode is performed (step S503).

When the user does not operate an operation for inputting that the user has performed a wiping operation on the seating unit 200 (step S506: No), the second manual mist mode is executed (step S507).

34 (a) and 34 (b) are perspective views illustrating the method for measuring the particle size according to the embodiment.

Laser diffraction is used for the measurement of the particle diameter. When laser is irradiated to microparticles | fine-particles, the diffracted scattering light which arises in various directions from this microparticle will be produced. The intensity of diffracted scattered light has a spatial pattern in the direction in which light is generated. This spatial pattern is called a light intensity distribution pattern. The light intensity distribution pattern is changed by the particle diameter of the fine particles. The particle size can be calculated by detecting the light intensity distribution pattern using the correlation between the particle diameter of the fine particles and the light intensity distribution pattern.

As shown to FIG. 34 (a) and FIG. 34 (b), the particle size measuring apparatus 600 has the light emitting part 601 and the light receiving part 602. FIG. The light receiving unit 602 is provided to receive the laser light emitted from the light emitting unit 601. In the measurement of the particle diameter, the laser emitted from the light emitting unit 601 is irradiated to the mist M sprayed from the spraying device 481. The light receiving unit 602 receives the diffracted scattered light generated by the laser irradiation. Thereby, the light intensity distribution pattern can be detected. Aerotrac LDSA-3500A (manufactured by MicrotracBEL Corp.) can be used for the measuring device.
