Description

TOILET DEVICE AND TOILET SEAT DEVICE}

The form of the present invention generally relates to a toilet device and a toilet seat device.

In the toilet device described in Patent Document 1, hypochlorous acid water or mist of tap water is sprayed onto the bowl of the toilet bowl automatically before use of the toilet device (for example, when the human body detection sensor detects the human body). Thereby, a water film is formed in the bowl portion, and adhesion or sticking to the surface of the bowl portion of dirt can be suppressed.

Japanese Patent No. 5029930

On the inner surface of the bowl portion of the toilet, there is a washing region through which washing water for discharging dirt in the bowl portion passes, and a non-cleaning region located above the washing region and through which washing water does not pass. Even in such a non-cleaning area, dirt may adhere. For example, dirt spattered from the cleaning area may adhere to the non-cleaning area. Therefore, in order to suppress contamination occurring in a wide range of toilets including a non-cleaning area as well as a cleaning area, it is preferable to emit mist not only in the cleaning area but also in the non-cleaning area. However, in the toilet device of Patent Document 1, there is a room for improvement from the viewpoint of suppressing the occurrence of bacteria and contamination in the non-cleaned area because the amount of mist entering the non-cleaned area is small. On the other hand, by automatically spraying a mist of tap water or sanitized water over a wide range including a non-cleaning area, it is possible to suppress generation of bacteria and contamination caused by dirt (user excrement, etc.) over a wide range. Thereby, for example, the frequency of cleaning by the 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 also included in the mist of the tap water or the mist of the sterilized water produced from the tap water. For this reason, when a mist of tap water or sanitized water generated from tap water is used, the scale (eg, calcium carbonate, etc.) may be precipitated by evaporation after the mist enters the toilet device.

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 dirt in the toilet. However, the scale component of the mist adhering to the non-cleaning area of the toilet is not washed by the washing water flowing in the toilet. For this reason, when mist of tap water or sanitized water is sprayed on the non-cleaning area, the scale may gradually grow in the non-cleaning area, and contaminants may be generated in the short time.

The scale contamination caused by the scale component of the tap water can be removed by wiping cleaning. However, if the scale contamination occurs in a short period of time, in order to reduce the frequency of cleaning, in the case where the mist of the sterilized water is automatically sprayed over a wide range including the non-cleaning area, cleaning is necessary to wipe off the scale contamination. A problem arises that the frequency cannot be reduced.

The present invention has been made on the basis of the recognition of this problem, and while suppressing the occurrence of bacteria or contamination in a wide range of toilet bowls including the non-cleaned area, it is possible to prevent the occurrence of smearing contamination in a short period of time in the non-cleaned area. It is an object to provide a toilet device and a toilet device that can be restrained.

The first aspect of the present invention includes a bowl portion receiving dirt, an upper surface of a rim positioned on the bowl portion, and a water jetting port for jetting cleaning water for discharging the dirt from within the bowl portion into the bowl portion, wherein the bowl portion comprises: A toilet having a cleaning area through which washing water passes, and a non-cleaning area located above and below the upper surface of the rim, a toilet seat installed on top of the toilet, and a spraying device for spraying mist And, a detection sensor for detecting the user, and a control device for controlling the spraying device based on the detection information of the detection sensor, the control device in the state that the detection sensor is not detecting the user When the user is detected, the mist is automatically controlled by controlling the spraying device and A pre-mist mode in which a mist or water film is formed by retaining mist in the cleaning area and the non-cleaning area, and the user is not detecting the user from the state in which the detection sensor detects the user. The water droplets or the water droplets may be increased by automatically controlling the spraying device when it is not in the state, and initiating mist to the water droplets or the water film formed in the non-cleaning area in the pre-mist mode, and increasing the water droplets or the water film volume. It is a toilet device characterized in that it is possible to perform an after-mist mode for washing the water film.

According to this toilet device, in the pre-mist mode, the mist sprayed from the spraying device forms water droplets or water films in the cleaning area and the non-cleaning area. Thereby, it is possible to suppress adhesion or fixation of dirt over a wide range in the bowl portion including the non-cleaning region. In addition, the undertaken mist stays in the cleaning and non-cleaning areas, and, for example, the water droplets or the water film are not washed until after-mist mode is performed. Thereby, it is possible to suppress the adhesion and fixation of dirt more than when the bowl portion is wet.

In addition, in the after-mist mode, the mist of the sterilized water sprayed from the spraying device starts to enter the non-cleaning area. Thereby, generation | occurrence | production of the bacteria and contamination by the dirt which was not washed with the washing water can be suppressed.

In addition, when the water droplets or water film formed by the pre-mist mode remain attached to the non-cleaning area, there is a case where scale is deposited by evaporation of the water or water film and staining occurs in the non-cleaning area. On the other hand, it is possible to suppress the water droplets or the water film remaining in the non-cleaned region by washing the water droplets or water film formed in the non-cleaned region by the after-mist mode. Thereby, generation | occurrence | production of the stain | pollution | contamination can be suppressed. By the above, it is possible to suppress the occurrence of stains and stains that can be visually observed in a short period of time in the non-cleaning area while suppressing the occurrence of bacteria and contamination in a wide range of toilet bowls including the non-cleaning area.

The second invention has a bowl portion receiving dirt, an upper surface of a rim located on the bowl portion, and a water jetting port for jetting cleaning water for discharging the dirt from within the bowl portion into the bowl portion, wherein the bowl portion comprises: A toilet seat apparatus installed on an upper portion of a toilet having a washing area through which washing water passes, and a non-cleaning area located above and below the upper surface of the rim, a seating part to be seated by a user, and a spraying device to spray mist And, a detection sensor for detecting the user, and a control device for controlling the spraying device based on the detection information of the detection sensor, the control device from the state that the detection sensor is not detecting the user When the user is detected, the mist is automatically controlled by controlling the spraying device.

The water droplet or by automatically controlling the spraying device when it is not in the state, and initiating mist to the water droplets or the water film formed in the non-cleaning area in the pre-mist mode, and increasing the water droplets or the water film volume. It is a toilet seat apparatus characterized in that it is possible to perform an after-mist mode for washing the water film.

According to this toilet seat apparatus, in the pre-mist mode, the mist sprayed from the spray apparatus forms a water droplet or a water film in the cleaning area and the non-cleaning area. Thereby, it is possible to suppress adhesion or fixation of dirt over a wide range in the bowl portion including the non-cleaning region. In addition, the undertaken mist stays in the cleaning and non-cleaning areas, and, for example, the water droplets or the water film are not washed until after-mist mode is performed. Thereby, it is possible to suppress the adhesion and fixation of dirt more than when the bowl portion is wet.

In addition, in the after-mist mode, the mist of the sterilized water sprayed from the spraying device starts to enter the non-cleaning area. Thereby, generation | occurrence | production of the bacteria and contamination by the dirt which was not washed with the washing water can be suppressed.

In addition, when the water droplets or the water film formed by the pre-mist mode remain attached to the non-cleaning area, the scale may precipitate due to the evaporation of the water or water film, causing contamination when staining the non-cleaning area. On the other hand, it is possible to suppress the water droplets or the water film remaining in the non-clean region by washing the water droplets or water film formed in the non-clean region by the after-mist mode. Thereby, generation | occurrence | production of the stain | pollution | contamination can be suppressed. By the above, it is possible to suppress the occurrence of stains and stains that can be visually observed in a short period of time in the non-cleaning area while suppressing the occurrence of bacteria and contamination in a wide range of toilet bowls including the non-cleaning area.

The third aspect of the present invention includes a bowl portion receiving dirt, an upper surface of a rim positioned on the bowl portion, and a water jetting port for jetting cleaning water for discharging the dirt from within the bowl portion into the bowl portion, wherein the bowl portion comprises: A toilet having a cleaning area through which washing water passes, and a non-cleaning area located above and below the upper surface of the rim, a toilet seat installed on top of the toilet, and a spraying device for spraying mist And, a detection sensor for detecting the user, and a control device for controlling the spraying device based on the detection information of the detection sensor, the control device from the state that the detection sensor is not detecting the user When the user is detected, the sprayer automatically controls the spraying device to spray mist. The first mode is operable, and the pre-mist mode is a first step of forming a water droplet or a water film by starting a mist in the non-clean region, and the water droplet or the water film formed in the non-clean region in the first process. It is a toilet device characterized by having a second process of washing the water droplets or the water film by starting the mist and increasing the volume of the water droplets or the water film.

According to this toilet device, the cleaning area and the non-cleaning area can be wetted before the user's toilet device is used by the pre-mist mode. Thereby, it is possible to suppress adhesion or fixation of dirt over a wide range in the bowl portion including the non-cleaning region.

When the water droplets or the water film formed by the pre-mist mode remain attached to the non-cleaning area, the scale may be precipitated by evaporation of the water or water film, and staining may occur in the non-cleaning area. On the other hand, it is possible to suppress the water droplets or the water film remaining in the non-clean region by washing the water droplets or water film formed in the non-clean region by the second step. Thereby, generation | occurrence | production of the stain | pollution | contamination can be suppressed. By the above, it is possible to suppress the occurrence of stains and stains that can be visually observed in a short period of time in the non-cleaning area while suppressing the occurrence of bacteria and contamination in a wide range of toilet bowls including the non-cleaning area.

In addition, in the pre-mist mode, if the mist is sprayed so that the undertaken mist flows out immediately, there is a concern that the mist may splash in the bowl portion and scatter out of the toilet because the mist has a large particle size or flow rate. On the other hand, in the present invention, the water droplet or water film is flown by increasing the volume of the water droplet or water film by the second step after forming the water droplet or water film by the first step. Thereby, it can suppress that a mist scatters out of a toilet.

The toilet 800 has a concave bowl portion 801 that receives dirt. The toilet seat apparatus 100 is installed on the upper portion of the toilet 800.

The toilet seat apparatus 100 has a casing 400 (body portion), a seating portion 200 (a toilet seat) to which a user sits, and a toilet seat cover 300. The seating part 200 and the toilet seat cover 300 are axially supported so as to be opened and closed with respect to the casing 400, respectively. The state of FIG. 1 is a state in which the seating portion 200 is closed (lowered), and the toilet cover 300 is opened (raised). The toilet seat cover 300 covers the seat surface of the seating portion 200 from above in the closed state.

Inside the casing 400, a body cleaning function part or the like that realizes cleaning of a user's human body part ("hip", etc.) sitting on the seating part 200 is built-in. In addition, for example, a seating detection sensor 404 for detecting that a user sits on the seating unit 200 is installed in the casing 400. In the case where the seating detection sensor 404 detects a user sitting in the seating unit 200, when the user operates the manual operation unit 500 such as, for example, a remote control, a cleaning nozzle (for convenience of description below, only “nozzle ”) (473) can be advanced into the bowl portion 801 of the toilet (800). In addition, in the toilet seat apparatus 100 shown in FIG. 1, the nozzle 473 shows the state which advanced into the bowl part 801.

One or a plurality of water jetting ports 474 are provided at the tip of the nozzle 473. Then, the nozzle 473 can spray water from the water jetting port 474 provided at the distal end portion to clean the user's "hip" or the like sitting on the seating portion 200.

In addition, in the present specification, each of "up", "down", "front", "rear", "left side", and "right side" has a user sitting on the seating portion 200 with the open toilet cover 300 back to the back. It is the direction seen from.

2 is a cross-sectional view illustrating a part of the toilet device according to the embodiment.

As shown in Fig. 2, the upper portion of the bowl portion 801 is a rim portion 805. The rim portion 805 is an annular portion forming the upper edge portion of the toilet 800. In the bowl portion 801, the aggregates 801w are collected.

In addition, the toilet 800 has a rim upper surface 806 located above the bowl portion 801. The upper surface of the rim 806 is the upper surface of the rim 805, for example, facing the rear surface 204 of the closed seat 200.

3 (a) and 3 (b) are schematic diagrams illustrating a part of the toilet device according to the embodiment.

3 (a) is a perspective view illustrating the toilet 800, and FIG. 3 (b) is a plan view illustrating the toilet 800. The toilet 800 has a water jetting port 811 installed on the rim portion 805. The water jetting port 811 discharges cleaning water for discharging dirt (eg, user's excrement) from the bowl portion 801 into the bowl portion 801.

For example, when the user performs the toilet washing operation by the switch installed on the remote control or the like, or when the user stands up from the seating portion 200, the toilet washing to supply the washing water from the water jetting port 811 into the bowl portion 801 is performed. Is executed. Thereby, dirt in the bowl portion 801 is discharged, and the surface of the bowl portion 801 is cleaned.

As shown by arrow A5 shown in Fig. 3 (a), the water jetting port 811 discharges the washing water toward the rear. The washing water discharged from the water jetting port 811 flows over the shelf-shaped portion 805B installed along the rim portion 805, and the swirling flow SF rotating in the bowl portion 801 as shown in Fig. 3 (b). ).

The bowl portion 801 has a cleaning area 801A through which the washing water passes, and a non-cleaning area 801B positioned above the cleaning area 801A and below the rim top surface 806. The washing area 801A is an area on the inner surface of the bowl portion 801 through which the washing water passes and becomes wet. The non-cleaning area 801B is an area on the inner surface of the bowl portion 801 through which the washing water does not pass. As shown in Fig. 3 (b), when viewed from above, the non-cleaning area 801B is generally annular along the rim portion 805, and the cleaning area 801A is located inside.

For example, as shown in FIG. 2, the cleaning area 801A is an area below the shelf-shaped portion 805B, and the non-cleaning area 801B is an elevation of the rim portion 805 located above the shelf-shaped portion 805B. (Inner rim surface).

In addition, in the embodiment, the washing water may not be in the form of forming swirl flow SF. For example, the water jetting port 811 may jet the washing water downward from the rim portion 805. Even in this case, the bowl portion 801 has a cleaning area through which the cleaning water passes, and a non-cleaning area located between the upper surface of the rim and the cleaning area and through which the cleaning water does not pass.

4 is a block diagram illustrating a main configuration of a toilet seat apparatus according to an embodiment.

In addition, FIG. 4 shows the constitution of the main parts of the water system and the electric system.

The toilet seat device 100 includes a solenoid valve 431, a sterilizing device 450, a switching valve 472, a spray device 481, a nozzle motor 476, a nozzle 473, a nozzle cleaning chamber 478, and a flow path (110 ~ 113). These are arranged in the casing 400, for example. In addition, as shown in FIG. 35, these may be mounted inside the toilet 800.

The flow path 110 is a flow path for guiding water supplied from an unshown water supply source such as a water supply or a water storage tank to a spray device 481 or a nozzle 473. The solenoid valve 431 is provided on the upstream side of the flow path 110. The solenoid valve 431 is a solenoid valve that can be opened and closed, and controls the supply of water based on a command from a control device 405 installed inside the casing 400.

Above the flow path 110, a disinfection device 450 for generating sterilized water is provided downstream of the solenoid valve 431. The sterilizing apparatus 450 generates sterilizing water containing, for example, hypochlorous acid. As the bactericidal device 450, for example, an electrolytic cell unit is exemplified. The electrolytic cell unit electrolyzes tap water flowing through a space (flow path) between the positive electrode plate (not shown) and the negative electrode plate (not shown) by controlling the energization from the control device 405. In addition, the number of germs is not limited to those containing hypochlorous acid. For example, the sterilizing water may be a solution containing metal ions such as silver ions or copper ions, a solution containing electrolytic chlorine or ozone, acidic water or alkaline water. The sterilizing device 450 is not limited to the electrolytic cell, and may be of any configuration capable of generating sterilizing water.

Above the flow path 110, a switching valve 472 is provided downstream of the disinfecting device 450. Downstream of the switching valve 472, a nozzle 473, a nozzle cleaning chamber 478, and a spraying device 481 are provided. The flow path 110 is a flow path 111 that guides water to the nozzle 473 by a switching valve 472, a flow path 112 that guides water to the nozzle cleaning chamber 478, and water to the spray device 481. It is branched to the euro 113 to deliver. The switching valve 472 controls opening and closing of the flow path 111, the flow path 112, and the flow path 113 based on commands from the control device 405. That is, the switching valve 472 controls the supply of water to the nozzle 473, the nozzle cleaning chamber 478, and the spray device 481. Further, the switching valve 472 switches the flow rate of water supplied downstream.

The nozzle 473 receives the driving force from the nozzle motor 476 to advance or retreat into the bowl portion 801 of the toilet 800. That is, the nozzle motor 476 moves the nozzle 473 forward and backward based on an instruction from the control device 405. The nozzle 473 is accommodated in the casing 400 when not in use. The nozzle 473 discharges water from the water jetting port 474 in the state of advancing forward from the casing 400 to clean the human body parts.

The nozzle cleaning chamber 478 cleans the outer circumferential surface (fuselage) of the nozzle 473 by spraying sanitized water or tap water from a water jetting hole installed therein.

The spraying device 481 makes the sterilized water generated in the tap water or the sterilizing device 450 a mist shape. The spraying device 481 sprays mist (mist of sterilized water or mist of tap water) to the bowl portion 801, the rim portion 805, and the seating portion 200. In other words, the spraying device 481 starts the mist of the sterilized water or the mist of the tap water to the bowl portion 801, the rim portion 805, and the seating portion 200. In addition, in this specification, "watering" means that water (sterile water or tap water) is attached to the surface of an object. In particular, in the case of "directly undertaken", it means that water (sanitized water or fine particles (p) of tap water) arrives at the surface of an object from the air.

In addition, a motor 511 (rotating device) for a toilet seat, a motor 512 for a toilet seat (rotating device), a blower 513 and a warm air heater 514 are provided inside the casing 400.

The toilet seat motor 511 is opened and closed by rotating the seating part 200 by electricity based on an instruction from the control device 405. The toilet cover motor 512 is opened and closed by rotating the toilet cover 300 by electric transmission based on an instruction from the control device 405.

The blowing device 513 is a fan installed inside the casing 400, for example. The blower device 513 operates based on a command from the control device 405. For example, the blade rotates according to the rotation of the motor of the blower 513. Thereby, the blower apparatus 513 can blow air toward the toilet 800 (for example, inside the bowl part 801). Further, the blowing device 513 may blow air to a local part of the user sitting in the seating portion 200. The warm air heater 514 warms the air sent to the outside of the casing 400 by the blowing device 513. Thereby, a warm air is sent toward the user's local part to dry the local part.

The toilet seat heater 515 (drying apparatus) is provided inside the seating part 200, for example. The toilet seat heater 515 has an annular metal member provided along the periphery of the opening 200a (FIG. 1) formed in the center of the seating portion 200, for example. The toilet seat heater 515 warms the seat 200 by applying electric power to the toilet seat heater 515 based on the command from the control device 405. As the toilet seat heater 515, for example, a tubing heater, a sheath heater, a halogen heater, or a carbon heater may be used. The metal member is made of, for example, aluminum or copper. In addition, various shapes such as a sheet shape, a wire shape, and a mesh shape can be adopted as the shape of the metal member.

A circuit for supplying power from a power supply circuit (not shown) is used in the control device 405. For example, the control device 405 includes an integrated circuit such as a microcomputer. The control device 405 is based on the detection information of the detection sensor 402 (for example, the human body detection sensor 403 or the seat detection sensor 404) detecting the user or the operation information of the manual operation unit 500 Valve 431, disinfection device 450, switching valve 472, nozzle motor 476, spraying device 481, blower 513, warm air heater 514, toilet seat heater 515, toilet seat motor 511, and the toilet cover motor 512 is controlled.

The manual operation unit 500 is an operation unit for the user to spray the sterilized water at an arbitrary timing, for example. For example, the manual operation unit 500 is a remote control having a switch or a button, and when the user operates the manual operation unit 500, operation information (signal) instructing spraying of the sterilizing water is sent to the control device 405. . The control device 405 controls the sterilizing device 450 or the spraying device 481 based on the operation information. Thereby, the user can spray the sterilized water by operating the manual operation unit 500.

In addition, the manual operation unit 500 may have a switch, a button, or the like for the user to operate each function of the toilet seat apparatus 100 as well as spraying sanitized water. When an operation corresponding to each function is performed, the operation information is sent to the control device 405, and the control device 405 controls the operation of each part of the toilet seat apparatus 100 based on the operation information.

The seating detection sensor 404 may detect a user's seating state (with or without seating) to the seating unit 200. The seating detection sensor 404 detects the user's seat and transfer. For the seating detection sensor 404, a microwave sensor, a range sensor (infrared flood sensor), an ultrasonic sensor, a tact switch, a capacitive switch (touch sensor), or a deformation sensor may be used. In this example, a distance sensor installed in the casing 400 is used for the seating detection sensor 404.

In addition, in the case of using contact sensors such as tact switches, electrostatic sensors, and deformation sensors, these contact sensors are installed in the seating unit 200. When the user sits on the seat 200, the tact switch is pressed down by the user's weight. Or, the user contacts the electrostatic sensor. Alternatively, pressure is applied to the deformation sensor by the weight of the user. The user's seating can be detected by the electric signal from these sensors.

The human body detection sensor 403 may detect a user in front of the toilet 800, that is, a user present in a position spaced apart from the seating part 200. That is, the human body detection 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, for example, a pyroelectric sensor, a microwave sensor, an ultrasonic sensor, or a range sensor (infrared flood sensor) can be used. In this example, a pyroelectric sensor provided in the casing is used for the human body detection sensor 403. Further, the human body detection sensor 403 may detect a user immediately after entering the bathroom by opening the door of the bathroom, or a user immediately before entering the bathroom, that is, a user existing in front of the door trying to enter the bathroom. For example, when a microwave sensor is used, it becomes possible to detect the presence of the user through the door of the bathroom.

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

The control device 405 is capable of executing three types of mist modes: an after mist mode, a pre mist mode, and a manual mist mode.

The after-mist mode is, for example, an operation mode in which the mist of the sterilized water is automatically sprayed based on the detection information of the detection sensor 402 after use of the user's toilet device 10. The pre-mist mode is, for example, an operation mode in which the mist of sanitized water or tap water is automatically sprayed based on the detection information of the detection sensor 402 before the user's toilet device 10 is used. The manual mist mode is an operation mode in which mist of the sterilized water is sprayed based on the operation information of the manual operation unit 500.

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

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

5 (b) is an enlarged view of a part of FIG. 5 (a). In addition, in FIG. 5 (b), a part of the casing 400 positioned in front of the spraying device 481 is omitted for easy viewing.

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 when the toilet seat apparatus 100 is installed on the upper side of the toilet 800.

The nozzle damper 479 is pivotably supported with respect to the casing 400. The nozzle 473 is located behind the nozzle damper 479 in a state of retreating into the casing 400. In cleaning the human body part, the nozzle 473 contacts the nozzle damper 479, rotates the nozzle damper 479 to open, and advances from the inside of the casing 400.

5 (c) to 5 (e) are enlarged perspective views showing the periphery of the nozzle damper 479 and the blower damper 516.

The blower damper 516 is pivotally supported with respect to the casing 400. A blower 513 is disposed behind the blower damper 516. The blower damper 516 covers the opening 516a of the casing 400. The air sent from the blower 513 is sent into the toilet 800 through the opening 516a.

5 (c) is a state in which the blowing device 513 is stopped, and FIGS. 5 (d) and 5 (e) show that the blowing device 513 is operating and blowing toward the bowl 801. State. As shown in Fig. 5 (c), in the state where the blowing is stopped, the blowing damper 516 is closed.

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

In the state of Fig. 5 (e), the amount of air blown by the blower 513 is higher (or the wind speed is higher) than the state of Fig. 5 (d). In this case, the blower damper 516 is rotated and opened more than the state of Fig. 5 (d). Thereby, the blower apparatus 513 blows air from the rear upper part in the bowl part 801 toward the front upper part in the bowl part 801 like arrow A2, for example.

In this way, the direction of the wind sent from the blowing device 513 is changed by the blowing damper 516. In other words, the blowing device 513 can control the blowing direction by the air volume (wind velocity). The range in which the mist starts by burning the mist sprayed from the spraying device 481 in the air stream generated by the blowing from the blowing device 513, and the amount of mist in each range (the number of bacteria to start in each range or You may control the amount of tap water).

6 (a) to 6 (c) are schematic diagrams illustrating the spray device according to the embodiment.

6 (a) is a perspective view of the spraying device 481, and FIG. 6 (b) is a side view of the spraying device 481.

The spraying device 481 has a motor 481a and a disk 481b connected to the lower side of the motor 481a. The 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. 6 (b), water W (tap water or sanitized water generated by the sanitizing device 450) is supplied to the upper surface of the disk 481b. During rotation of the disk 481b, the water W is supplied, so that the spraying device 481 sprays the water W in a mist shape.

Fig. 6 (c) is an enlarged view of a portion of the disk 481b seen from above. The water W dropped on the upper surface of the rotating disk 481b spreads in a film shape on the disk 481b by centrifugal force and is radiated from the disk 481b. At this time, the water W is divided into a film shape from the vicinity of the edge of the disk 481b, or after being formed into a thread shape, and then divided into fine particles p (mist). The particle size (diameter of the particle p) of the mist can be controlled by the rotational speed of the disk 481b, that is, the rotational speed of the motor 481a. The higher the rotational speed, the smaller the particle size 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 suitably 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.

Incidentally, in the present specification, the particle diameter is the particle diameter of the fine particles p present in the air before embarking on the toilet device 10, and is, for example, the Sauter average particle diameter (total volume / total surface area). The method of measuring "particle size" in the present specification will be described later with reference to FIG. 34. In addition, the mist means a range in which the particle diameter is 10 micrometers (µm) or more and 300 μm or less. If the particle size of the mist is less than 10 µm, a long time is required to wet the target areas such as the bowl portion 801, the rim portion 805, and the seating portion 200. In addition, when a sterilizing water containing hypochlorous acid is used, if the particle size of the mist is less than 10 µm, the concentration of hypochlorous acid in the mist tends to attenuate, and the sterilization performance tends to deteriorate. On the other hand, when the particle size of the mist is larger than 300 µm, the mist is difficult to diffuse and it is difficult to spray the mist over a wide range. In the following description, the particle size of the large particle size is 100 m to 300 m, preferably 150 m to 300 m, and the particle size of the medium particle is 50 m to 200 m, preferably It is a mist in the range of 60 µm or more and 150 µm or less, and the mist of the small particle size is a mist in the range of 10 µm or more and 100 µm or less, preferably 10 µm or more and 60 µm or less.

For example, the position or number of the water supply port 481c, the particle size of the mist sprayed from the spraying device 481 toward the toilet 800 by the rotational direction (clockwise or counterclockwise) of the disk 481b, It is also possible to adjust the flow rate, direction, and the like. Thereby, you may control the range to which the mist sprayed from the spraying device 481 starts, and the amount of mist to start in each range. Further, 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 device according to a modification of the embodiment.

Fig. 7 shows a cross section in the line A-A 'shown in Fig. 5 (a).

As shown in FIG. 7, the slit S is provided in the casing 400. In this example, the spray device 481 is disposed within the casing 400, and the slit S is located in the lower front of the spray device 481. For example, the height (position in the vertical direction) of the top surface S1 of the slit S is the same as the height of the bottom surface B1 of the disk 481b, and the top surface S1 and the bottom surface B1. ) Is 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 slightly downward than horizontal. The mist M sprayed from the disk 481b passes through the slit S, and is sprayed toward the bowl portion 801. Thereby, it is possible to prevent contamination (Y) of urine or the like from adhering to the spraying device 481 without impairing the design and cleanability of the toilet device 10. In addition, the disk 481b may have a flat disk shape, or may have a concavo-convex shape or use a conical shape or a sphere as appropriate. Thereby, the spraying direction of the mist, the particle size of the mist, etc. can also be adjusted.

The spraying device 481 is disposed below a part of the seating portion 200 in the state that the toilet seat apparatus 100 is installed on the upper portion of the toilet bowl 800 (see FIG. 2), and the mist is directed into the toilet bowl 800. Spray.

In addition, in the embodiment, the spraying device is not limited to the devices described with respect to FIGS. 6 and 7. For example, an ultrasonic atomization device may be used as the spraying device. The ultrasonic atomization device makes the liquid a mist by irradiating the liquid with ultrasonic waves. Further, for example, a two-fluid nozzle may be used as the spraying device. The two-fluid nozzle makes the liquid mist by spraying gas and liquid together. However, when the apparatus described with reference to Figs. 6 and 7 is used, there is an advantage that the spraying range can be easily controlled by the blower 513. In addition, the risk of clogging is low, and additional devices such as a compressor are also unnecessary.

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

In this example, a 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 device 481 in the closed state.

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

8 (b) and 8 (c) enlarge the periphery of the nozzle damper 479 and the mist damper 482. 8 (b) is a state in which the nozzle 473 is retracted into the casing 400. At this time, the nozzle damper 479 is closed, and covers the front of the nozzle 473. In addition, the mist damper 482 is closed, 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 portion 801 side by the mist damper 482 as shown in Fig. 8 (b). Thereby, it is possible to further prevent urine or contamination from adhering to the spraying device 481.

Fig. 8 (c) shows a state in which the nozzle 473 advances forward and the nozzle damper 479 is rotated. At this time, the advancement distance of the nozzle 473 to the front may be shorter than the advancement distance of the human body at the time of local washing. For example, the tip of the nozzle 473 is in contact with the nozzle damper 479. Further, in Fig. 8 (c), 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) in which the mist of the sterilized water or tap water is undertaken. Fig. 10 (a) shows an example of the starting amount (starting amount per unit area) of each target site in each mist mode in four stages: "large", "medium", "small", and "minimum".

The control device 405 automatically controls the spraying device 481 when the detection sensor 402 is in a state of detecting the user from a state in which the user is not detecting the user, and the mist portion of the mist of the tap water or the sterilized water bowl The premist mode spraying in 801 is feasible.

For example, as shown in FIG. 9, when the user enters the bathroom and the human body detection sensor 403 detects the user's room, a signal indicating the user's room (detection information) is transmitted to the control device 405. The control device 405 automatically executes the premist mode based on the signal. In the pre-mist mode, the control device 405 sprays mist of the tap water on the spraying device 481 to start the mist on the target site. As shown in Figs. 10 (a) and 10 (b), the target site in the pre-mist mode is the target site P3 (non-cleaned area 801B of the bowl portion 801) and the target site P4) ( It is a washing area 801A of the bowl portion 801). In the pre-mist mode, the seating portion 200 and the rim top surface 806 of the rim portion 805 are not targeted for spraying.

In this way, in the pre-mist mode, the mist sprayed from the spraying device 481 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, it is possible to suppress the adhesion and fixation of dirt in a wide range of the toilet 800 including the non-cleaning region 801B.

The control device 405 automatically controls the spraying device 481 when the detection sensor 402 is in the state of not detecting the user from the state in which the user detects the user, and removes the mist of the sterilized water in the toilet 800 and It is possible to perform an after-mist mode spraying on the seating unit 200.

For example, as shown in FIG. 9, when the user leaves the bathroom and the human body detection sensor 403 detects the user's departure, a signal indicating the user's departure (detection information) is transmitted to the control device 405. The control device 405 automatically executes the aftermist mode based on the signal. In the after mist mode, the control device 405 generates sterilized water in the sterilizing device 450, and sprays the mist of the sterilized water to the spraying device 481 to start the mist on the target site. As shown in Figs. 10 (a) and 10 (b), the target portion in the after-mist mode is the target portion P1 (surface 203 of the seating portion 200), the target portion P2 (sitting portion) It is the back surface 204 of the 200 and the upper surface of the rim 806), the target site P3, and the target site P4.

In this way, after the use of the user's toilet device 100 by the execution of the after-mist mode, it is possible to automatically start sterilizing water in the toilet 800 and the seat 200. Thereby, the generation | occurrence | production of a fungus and contamination can be suppressed automatically in the wide range of the toilet seat 800, as well as the seating part 200, etc.

The control device 405 is capable of executing a manual mist mode in which the mist of the sterilized water is sprayed into the toilet 800 and the seating part 200 by controlling the spraying device 481 when the user operates the manual operating part 500. Do.

For example, as shown in FIG. 9, when the user operates the manual operation unit 500 while entering the bathroom (for example, after the execution of the pre-mist mode), a signal according to the operation (operation information) is controlled. ). The control device 405 executes the manual mist mode based on the signal. The manual mist mode is executed at a timing such as before, after, and when the toilet seat apparatus 100 is used. In the manual mist mode, the control device 405 generates sterilized water in the sterilizing device 450, and sprays the mist of the sterilized water to the spraying device 481 to start the mist on the target site. The target sites in the manual mist mode are the target sites P1, the target sites P2, the target sites P3 and the target sites P4 as shown in Figs. 10 (a) and 10 (b).

In this way, at the timing when the manual operation unit 500 is operated by the manual mist mode, the sterilized water is launched into the toilet 800 and the toilet 200 to be wide, including the toilet 200 as well as within the toilet 800. In the range, occurrence of bacteria and contamination can be suppressed. In addition, the user can remove the bacteria or contamination generated in the seating unit 200 by wiping off the mist of the sanitizing water that has landed on the seating unit 200. For example, it is possible to sterilize the sterilized water that has started up against sticking contamination, which is difficult to suppress by the after-mist mode, by wiping with a toilet paper or the like. In addition, for example, a user who is concerned about contamination of the seat 200 before using the toilet seat apparatus 100 can sterilize the seat 200 by a manual mist mode. Since the sterilization is performed based on the user's own operation, it is possible to increase the user's security and satisfaction.

11 is a cross-sectional view illustrating an operation in the pre-mist mode of the toilet seat apparatus according to the embodiment.

11, the non-cleaning area 801B of the bowl portion 801 has a front-side non-cleaning area 801F. The front end side non-clean area 801F is a front end part of the non-clean area 801B, and is located at the center in the left-right direction of the bowl part 801, for example. The front-end non-clean area 801F includes a front end of the non-clean area 801B, and extends vertically from the top of the cleaning area 801A to the upper rim 806 of the rim.

In order to suppress adhesion of dirt and the like in the bowl portion 801, it is preferable to emit a lot of mist so that a water film is also formed in the non-cleaning region 801B. Thus, a method of operating the blower device 513 to generate airflow in the bowl portion 801 and sending mist to the non-cleaning area 801B by the airflow is considered. However, in this case, there is a case where the mist in which the airflow is carried also starts to the seating part 200 and the upper surface of the rim 806. Then, when the user seats the seat 200 or when the seat 200 is rotated by hand, there is a fear that the user's buttocks or hands come into contact with the mist launched into the seat 200 and may cause discomfort. In addition, since the upper surface of the rim 806 is formed substantially horizontally, there is a fear that the mist starting on the upper surface of the rim 806 falls out of the toilet 800.

Therefore, in the pre-mist mode, the control device 405 does not operate the blowing device 513 that generates the upward airflow in the bowl portion 801. In addition, in the pre-mist mode, the control device 405 sprays the mist to directly spray the mist into the non-cleaning area 801F at the front end without the mist starting on the upper surface 806 falling out of the toilet 800. The spraying device 481 controls the speed of the mist sprayed so that the mist sprayed from 481 reaches the front-side non-cleaning area 801F while remaining straight.

In this way, while starting a large amount of mist in the non-cleaning area 801B, the mist does not float on the rising air flow generated by the blower 513, so that it starts on the upper surface 806 or the seating portion 200. The amount of mist to be suppressed can be suppressed. Thereby, it is possible to suppress the mist that has started on the upper surface of the rim 806 from falling out of the toilet 800. In addition, the seating portion 200 can be suppressed from being wet by the mist, so when the user seats the seating portion 200 or when the seating portion 200 is rotated by hand, the user's buttocks or hands are seated ( 200) can be suppressed from coming into contact with the mist.

In addition, in this specification, a "water mist" includes water droplets and a water film formed by agglomeration after the mist starts.

For example, in the pre-mist mode, the control device 405 controls the speed of the mist (the speed at which the fine particles p fly) or the particle size of the mist by controlling the rotation speed of the disk 481b of the spraying device 481. Control. For example, the higher the speed of the mist, the easier it is for the mist to remain straight.

In FIG. 11 (and FIGS. 14, 17, 20, 24, 25, 27, 28, 30, and 31 described later), the path of the mist M sprayed from the spraying device 481 is arrowed. 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 has a spread up and down.

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

The particle diameter of the mist sprayed from the spraying device 481 has a distribution. For example, as shown in FIG. 12, a mist M1 of a small particle diameter (fine particles p1 of tap water or sanitized water) and a mist M2 of medium or large diameter (mapped water or bacteria) from the spraying device 481 A number of fine particles (p2)) are sprayed. The fine particles (p2) of the mist (M2) are easy to advance horizontally or downward because of their large weight. On the other hand, since the fine particle p1 of the mist M1 has a small weight itself, it may proceed upward due to the influence of air flow.

For this reason, as shown in Fig. 11, a distribution also occurs in the amount of mist that is launched into the non-cleaning region 801F at the front end. The volume zone (BZ) is a portion of the front-side non-cleaning area 801F that is most directly initiated by the mist. In the embodiment, the control device 405 controls the spraying device 481 so that the mist reaching the volume zone BZ remains straight.

13 is a schematic view for explaining the straight state of the mist.

Whether or not the mist sprayed from the spraying device 481 remains in a straight state is determined as follows.

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

The mist is sprayed on the object to be sprayed (OB) from the spray device (481), and the start point (Pt1) of the mist in the object to be sprayed (OB) is measured. The launching point Pt1 is a point where the most mist of the object to be sprayed OB directly starts. For example, it is possible to visualize the starting point Pt1 by receiving mist on a water-receiving test paper or a transparent plate, and observing the distribution of water droplets.

The spraying direction Ds (spray angle θs) in which the spraying device 481 sprays mist is measured. The spraying direction Ds is a direction in which the most mist is sprayed in the vicinity of the spraying device 481. Note that the distance from the spraying device 481 is within a range of, for example, 50 mm or less from the spraying device 481. For example, the spraying direction Ds can be measured by acquiring an image of the spraying device 481 spraying the mist and performing image processing. Alternatively, the mist sprayed may be visualized by irradiating the mist with a sheet laser, and the spraying direction Ds may be measured. The spray angle θs is an angle between the horizontal direction and the spray direction Ds.

The height h1 of the intersection point Pt2 between the straight line L1 extending in the spraying direction Ds and the spray object OB is calculated from the spraying device 481. 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 launch height h2 is measured. The starting height h2 is the distance along the vertical direction between the spraying device 481 and the starting point Pt1.

When the starting height h2 is equal to the height h1, it is determined that the mist sprayed from the spraying device 481 has reached the object to be sprayed OB while remaining straight. In addition, the range in which the starting height h2 is equal to the height h1 shall include the case where the difference between the starting height h2 and the height h1 is within 20 mm.

14 is a cross-sectional view illustrating the operation in the pre-mist mode of the toilet seat apparatus according to the embodiment.

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

As shown in FIG. 14, the front-side non-cleaning 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 non-clean region 801F, and is a curved surface shape having a downward slope toward the inside of the bowl portion 801. The mist guide portion 824 is installed below the R portion 823 and has a downward slope toward the outside of the bowl portion 801. Alternatively, the mist guide portions 824 may extend in the vertical direction. The mist guide part 824 is continuous with the R part 823.

The R part 823 is located near the upper surface of the rim 806. Therefore, when the spraying direction Ds in which the spraying device 481 sprays the mist is a direction in which many mists enter the R part 823, the rim upper surface 806 tends to get wet. In this case, there is a fear that the mist that has started on the upper surface 806 of the rim falls out of the toilet 800. Further, since the R part 823 has a downward slope toward the inside of the bowl part 801, the mist reaching the R part 823 is easily reflected by the R part 823 and scattered toward the upper surface of the rim 806. . In particular, when the speed of the mist is increased so that the mist reaches the non-cleaning area 801B while maintaining the straight state, the mist tends to scatter.

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

In addition, in the example shown in FIG. 14, the mist guide part 824 has a downward inclination toward the outside of the bowl part 801 and induces the mist that has reached the front end non-clean region 801F downward. For example, the mist that has reached the mist guide portion 824 is reflected downward. Thereby, it is possible to suppress the mist from scattering toward the upper surface of the rim even when the speed of the mist is increased so as to reach the front-side non-cleaning region 801F while the mist is kept straight.

In addition, the spraying part (for example, the disk 481b) for spraying mist is provided below a part of the seating part 200. In addition, the spraying direction Ds in which the spraying device 481 sprays mist is set in an inclined direction toward the front-end non-cleaning area 801F. Thereby, the mist which reached the front-end non-clean area 801F becomes easy to scatter downward. That is, the mist tends to be reflected downward in the non-clean region 801F at the front end. Therefore, it is possible to suppress the mist from scattering toward the upper surface of the rim even if the speed of the mist is increased so as to reach the non-cleaning area 801F at the front end while the mist is kept straight.

In addition, the spraying device 481 has a virtual line segment L2 (see FIG. 11) connecting the spraying part (for example, the disk 481b) and the front-side non-cleaning area 801F and the seating part 200. They are arranged not to cross. And, the spray direction (Ds) is set so that the mist reaching the front-side non-cleaning region 801F while maintaining the straight state is sprayed along the line segment L2. Thereby, mist can be started to the non-cleaning area | region 801B, suppressing wetness of the seating part 200 by a mist.

In addition, in the pre-mist mode, the control device 405 averages the amount of mist per unit area of the mist that directly emits the upper area 821 of the front-side non-cleaning area 801F, the lower area of the front-side non-cleaning area 801F ( The spraying device 481 is controlled to be smaller than the average amount of water per unit area of the mist that directly emits at 822).

Specifically, for example, in the pre-mist mode, the control device 405 sprays the device 481 so that the particle size of the mist directly attacking the lower area 822 is larger than the particle size of the mist directly entering the upper area 821. ) Control. By increasing the particle size of the mist directly hitting the lower region 822, it is possible to increase the average amount of water per unit area of the mist directly hitting the lower region 822. In addition, by reducing the particle size of the mist directly landing on the upper region 821, the average landing amount per unit area of the mist directly landing on the lower region 822 can be reduced.

By relatively increasing the average number of mists per unit area of the mist directly impinging on the lower region 822, it is possible to suppress adhesion or fixation of dirt in the lower region 822. On the other hand, it is possible to suppress the amount of mist that lands on the rim top surface 806 or the seating portion 200 by relatively reducing the average landing amount per unit area of the mist that directly lands on the upper region 821. For example, it is possible to suppress the mist reaching the upper region 821 from being scattered on the upper rim 806 or the seating portion 200. Thereby, it is possible to suppress the mist that has started on the upper surface 806 of the rim from falling out of the toilet. In addition, the seating portion 200 can be suppressed from being wet by the mist, so when the user seats the seating portion 200 or when the seating portion 200 is rotated by hand, the user's buttocks or hands are seated ( 200) can be suppressed from being contacted with the mist initiated.

15 (a) to 15 (c) are schematic diagrams for explaining a method for measuring an average amount of water per unit area of mist that directly emits in the upper and lower regions of the non-cleaned area.

First, the first measurement point (SU) including the upper area 821 of the front-side non-cleaning area 801F and the second measurement point including the lower area 822 of the front-side non-cleaning area 801F ( SL). The range of the left and right directions of the first measurement point SU and the second measurement point SL is a range of 100 mm in width centering on the tip of the non-clean area 801B, respectively. In addition, the range in the vertical direction of the first measurement point SU is substantially the same as the range in the vertical direction of the upper region 821, and the range in the vertical direction of the second measurement point SL is the vertical direction of the lower region 822. It is roughly the same as the range of.

After spraying the mist on the non-cleaning area 801F at the front end side, after a specified period of time, wipe each of the first measuring point (SU) and the second measuring point (SL) with Kim towel (manufactured by NIPPON PAPER CRECIA CO., LTD.) Pay. Thereby, the mist which started at each of the 1st measurement location SU and the 2nd measurement location SL is absorbed in a kim towel.

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

The difference between the weight of the kim towel that absorbs the mist that has started at the first measurement point (SU) and the weight of the kim towel before igniting the mist is the amount of mist started at the first measurement point (SU). The value obtained by dividing the landing amount of the mist that has started at the first measurement point (SU) by the area of the first measurement point (SU) is taken as the average amount of water per unit area of the mist that is directly launched into the upper region 821.

Likewise, the difference between the weight of the kim towel absorbing the mist that has started at the second measurement point SL and the weight of the kim towel before the mist is started is the amount of mist that has started at the second measurement point SL. The value obtained by dividing the landing amount of the mist that has started at the second measurement location SL by the area of the second measurement location SL is taken as the average launching amount per unit area of the mist that is directly launched into the lower region 822.

In addition, instead of wiping each measuring point with a kim towel, spraying may be performed while the kim towel is attached to each measuring point, and the mist may be absorbed in the kim towel. For example, a kim towel formed by folding into four originally is unfolded, and a kim towel that is not folded is cut into a shape according to each measurement point. The cut kim towel is attached to each measurement point.

In the above example, the R portion 823 and the mist guide portion 824 are used as the upper region 821, and the lower portion 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 is not limited to this, and may be a center in the vertical direction of the front-end non-clean region 801F. That is, the upper region is the upper region 821 than the center in the vertical direction of the front end non-clean region 801F, and the lower region 822 is lower than the center in the vertical direction of the front end non-clean region 801F. ).

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

As shown in Fig. 16 (a), the upper region 821 has an inclined surface (mist guide portion 824) inclined downward toward the outside of the bowl portion 801. As already described, the mist guide portion 824 (the 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 portion 801. Thereby, the lower region 822 induces the mist reaching the lower region 822 upward. As a result, a part of the mist that has reached the lower region 822 can be launched into the upper region 821, and the amount of inception in the upper region 821 (indirect initiation amount) 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 upper surface of the rim 806. 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 an 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 aggressively downward. In addition, the amount of mist induced upward by the lower region 822 can be suppressed by the small inclination angle θ2. 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 decelerated in the inclined surface of the upper region 821, so it is scattered 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 a pre-mist mode and an automatic toilet lid open mode.

The control device 405 automatically controls the toilet lid motor 512 when the detection sensor 402 is in a state of detecting the user from a state in which the user is not detecting the user, from the closed state of the toilet cover 300 The automatic toilet cover opening mode in the open state is feasible.

For example, when the user is not in the bathroom, the toilet seat cover 300 is closed. Thereafter, when the user enters the bathroom and the human body detection sensor 403 detects the user's entrance, the control device 405 executes an automatic toilet cover opening mode. Further, the control device 405 executes the pre-mist mode during the execution of the automatic toilet lid open mode.

For example, when the automatic toilet lid opening mode is executed, and the toilet lid 300 is opened as shown by arrows A6 in FIGS. 17 (a) and 17 (b), the bowl portion 801 and the bowl portion 801 are opened. A rising air flow f1 is generated in the vicinity of the toilet according to the opening operation of the toilet cover 300. In the example of FIG. 17 (a), a part of the mist M sprayed by the pre-mist mode has risen to the upper portion of the bowl portion 801 aboard the upward airflow f1. In this case, the mist rising above the bowl portion 801 starts to land on the seating portion 200 or the upper surface of the rim 806.

On the other hand, in the example of Fig. 17 (b), the control device 405 prevents the mist flying toward the front-end non-cleaning area 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 controlled. Specifically, the control device 405 limits, for example, the rotational speed of the disk 481b of the spraying device 481 so that the particle size of the mist does not become too small.

This allows the mist to reach the non-cleaning area 801B while suppressing mist from entering the rim top surface 806 or the seating portion 200 even when the rising air flow f1 occurs due to the automatic toilet cover opening mode. have. Therefore, it is possible to suppress the mist that has started on the upper surface of the rim 806 from falling out of the toilet 800. In addition, the seating portion 200 can be suppressed from being wet by the mist, so when the user seats the seating portion 200 or when the seating portion 200 is rotated by hand, the user's buttocks or hands are seated ( 200) can be suppressed from coming into contact with the mist.

In addition, the range in which the mist does not rise upward from the bowl portion 801 by the rising air flow f1 is such that not all mists do not rise upward from the bowl portion 801, but also does not cause discomfort to the user. It may be assumed that a slight mist of s rises upward from the bowl portion 801.

18 is a timing chart illustrating the operation in the pre-mist mode of the toilet seat apparatus according to the embodiment.

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

As shown in FIG. 18, the user's entrance is detected by the entrance detection means, such as the human body detection sensor 403, at time T1, for example. Then, the control device 405 starts execution of the automatic toilet cover open mode and the pre-mist mode. Thereby, the toilet seat cover 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 continue from the time T1 to the time T4, and at the time T4, the toilet lid 300 is brought into the full open state.

19B illustrates the range in which the mist sprayed from the spraying device 481 starts from the time T1 to the time T2. In this way, in the time period immediately after the start of the pre-mist mode and the automatic toilet seat cover opening mode, the control device 405 allows the mist to start in an area (clean area 801A) other than the non-clean area 801B of the bowl portion 801. The spray device 481 is controlled.

19 (a) illustrates the range in which the mist sprayed from the spraying device 481 starts from the time T2 to the time T3. Between the time T2 and the time T3, the control device 405 controls the spraying device 481 so that the mist starts in the non-cleaning area 801B.

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

Then, until the time T5 after the time T4, the automatic toilet lid opening mode and the pre-mist mode are finished. For example, at time T5, the user seats at the seating unit 200.

The size of the rising air flow f1 generated according to the opening operation of the toilet lid 300 by the automatic toilet lid opening mode is immediately after the toilet bowl 300 is opened from the closed state (that is, when the toilet lid starts to open). It is the easiest to grow. In contrast, in the embodiment, the control device 405 starts spraying mist toward the front end non-cleaning area 801F after the start of the automatic toilet cover opening mode. That is, as shown in FIG. 18, spraying of mist to the front-end non-cleaning region 801F is started at a time T2 after the time T1 when the automatic toilet lid opening mode starts. Thereby, it can suppress more that a mist rises upward from the bowl part 801 by the rising air flow f1.

In addition, the size of the rising air flow f1 generated according to the opening operation of the toilet lid 300 by the automatic toilet lid opening mode is likely to increase when the toilet lid 300 is opened at a high speed. On the other hand, as shown in Fig. 18, the control device 405 opens the toilet lid 300 in the first time period (from the time T1 to the time T2) immediately after the start of the automatic toilet lid opening mode. The motor 512 for the toilet cover is controlled so that the speed becomes lower than the speed at which the toilet cover 300 opens in the second time period (time T2 to time T3) after the first time period. Thereby, the rising air flow f1 can be made small immediately after the start of the automatic toilet cover opening mode. Therefore, it is possible to further suppress the mist from rising upward from the bowl portion 801 by the rising air flow f1 by the automatic toilet lid opening mode.

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

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

Fig. 20 (b) is an enlarged view of the region R4 shown in Fig. 20 (a).

The broken arrow indicates the airflow formed by the blower 513 (the same applies to FIGS. 24, 27, 28, and 30 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 (in the washing area 801A or in the non-washing area 801B). As a result, an upward air flow U1 is wound up from the toilet 800 below the seating portion 200 to the upper side of the seating portion 200.

For example, in the after mist mode or the manual mist mode, some mist is emitted from the spray device 481 toward the non-clean area 801B. In addition, the mist having a relatively large particle size starts the cleaning region 801A. The mist having a relatively small particle size is embarked on the upper surface of the rim 806, the seating portion 200, the toilet cover 300, and the like by the rising air flow U1. Thereby, the corners of the toilet device 10 including the non-cleaning area 801B, the upper surface of the rim 806, the seating portion 200, the toilet seat cover 300, and the like can be sterilized.

In general, tap water may contain scale components (eg, sodium, calcium, potassium, magnesium, etc.). In this case, the scale component is also included in the mist of the sterilized water generated from the tap water. When the mist containing the scale component evaporates after it starts to the toilet seat apparatus 100 or the like, scale may be deposited on the part where the mist has started, and contamination may occur in a short time.

So, in one embodiment of the toilet seat apparatus 100, the after-mist mode sprays the mist only in the toilet 800 as well as the mode in which the mist is sprayed on the toilet 800 and the seat 200 (second mode). It has a first mode. In the one-time aftermist mode, the control device 405 executes either the first mode or the second mode.

For example, in the first mode, the control device 405 stops the blowing device 513 so that the mist starts only in the toilet 800 (the cleaning area 801A and the non-cleaning area 801B), or the mist Control the particle size of In the first mode, it is possible to suppress the occurrence of bacteria and contamination in the toilet 800 by spraying the mist of the sterilizing water into the toilet 800. In addition, the scale component included in the mist launched into the toilet 800 is washed off by the washing water flowing into the toilet 800. Therefore, the first mode of spraying the mist only in the toilet 800 suppresses the occurrence of bacteria and contamination in the toilet 800 and also causes visible contamination due to the scale component, the upper surface of the rim 806, seating It can be suppressed from occurring in the portion 200, the toilet cover 300, and the like.

On the other hand, in the second mode, the control device 405 operates the blowing device 513 or controls the particle size of the mist so that the mist starts on the seating part 200 and the like, for example, as in the example of FIG. 20. In the second mode, by spraying the mist of the bacteria-removing water into the toilet seat 800 and the sitting portion 200, it is possible to suppress the occurrence of bacteria and contamination not only in the toilet bowl 800 but also in the sitting portion 200.

In addition, in the after-mist mode, the frequency at which the mist is attached to the seat 200 is lower than when the control device 405 executes the second mode each time by executing one of the first mode and the second mode. You can. Thereby, it is possible to lengthen the period until the scale on which the deposited mist evaporates and evaporates and grows into visible scale contamination. Therefore, it is possible to suppress the occurrence of stains that can be visually observed in a short period of time in an area in which cleaning water such as the seating portion 200, the toilet seat cover 300, and the upper surface of the rim does not flow.

In addition, since any of the first and second modes in the after-mist mode is executed, since the mist of the sterilized water is sprayed into the toilet 800 where contamination is likely to occur, the frequency of cleaning by the user is ensured 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 800, it is difficult to cause visible contamination without spraying the mist of the sterilized water to the seating part 200 each time.

In addition, in the range in which the mist starts only in the toilet 800 in the first mode, not only the case in which all the mist starts in the toilet 800, but also a slight amount of mist that does not contribute to the visually visible scale contamination It may be assumed to include the case of starting with (200).

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

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

At this time, the control device 405 automatically determines which of the first mode and the second mode of the after-mist mode is executed (step S102). Thereby, since the user does not have to select any one of the first mode and the second mode each time, the burden on the user can be reduced.

For example, in step S102, the control device 405 determines that the execution frequency of the second mode is lower than the execution frequency of the first mode. Due to the low frequency of execution of the second mode, the amount of mist containing the scale component attached to the seating portion 200 can be reduced. Therefore, it is possible to lengthen the period until the scale precipitates and grows with visible contamination.

More specifically, the control device 405, for example, when a predetermined time has elapsed since the execution of the second mode of the previous time, or when the first mode is executed a predetermined number of times after the execution of the second mode of the previous time (step S102: Yes), the second mode is executed again (step S103), and the aftermist mode ends. Thereby, since the 2nd mode is performed regularly, the generation | occurrence | production of the germ and contamination by a dirt can be suppressed, suppressing the occurrence of contamination in the short term which can be seen visually.

On the other hand, if the predetermined time has not elapsed since the execution of the second mode of the previous time, or the control device 405 has not executed the first mode a predetermined number of times after the execution of the second mode of the previous time (step S102: No) ), The first mode is executed (step S104), and the aftermist mode is ended. The predetermined time or the predetermined number of times in step S102 may be appropriately determined so that contamination of the scale does not occur in a short period of time in consideration of the concentration of the scale component contained in the tap water or the spray amount of mist.

22 is a flowchart illustrating another operation in the aftermist 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, a switch or button for a user to select which of the first mode and the second mode to execute is installed in the manual operation unit 500.

The user performs an input operation to select one of the first mode and the second mode in the manual operation unit 500. Then, the control device 405 receives information indicating which mode the user has selected (step S201).

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

If the detection sensor detects the user's departure when the user selects the second mode in the manual operation unit 500 (step S204: Yes), the control device 405 executes the second mode (step S205), and aftermist The mode ends. In addition, if the user's exit 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 of the first mode and the second mode to be executed by operating the manual manipulation unit 500.

For example, if the setting is not changed, the control device 405 executes either the first mode or the second mode each time in the after-mist mode. The concentration of scale components in tap water varies from region to region. In the region where the concentration of the scale component is low, even if the second mode in which the mist is sprayed on the seating portion 200 is executed each time, the period is long until the visible scale contamination due to the scale component occurs. In such an area, by performing the second mode in the after-mist mode, it is possible to reduce the frequency of cleaning by suppressing the occurrence of bacteria or contamination caused by dirt. On the other hand, in the region where the concentration of the scale component is high, when the second mode in which mist is also sprayed to the seating portion 200 is executed, it is easy to cause visual contamination caused by the scale component in a short period of time. In such an area, the frequency of cleaning may be reduced by not performing the second mode in which mist is sprayed onto the seating unit 200. The user can select which of the first mode and the second mode to be executed by the manual operation unit 500 to lower the frequency of cleaning in both high and low areas where the concentration of scale components contained in tap water is high.

Further, the manual manipulation unit 500 may be provided with a switch or a button for selecting at least one of the execution frequency of the first mode and the execution frequency 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 in the manual manipulation unit 500. In addition, for example, when the second mode is executed when the first mode is executed a predetermined number of times after the previous second mode is executed, the user can select the predetermined number of times in the manual manipulation 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) in the manual operation unit 500. Thereby, it is possible to select the execution frequency of the first mode or the execution frequency of the second mode so that the frequency of cleaning becomes low according to the concentration of scale components contained in the tap water in the area where the toilet apparatus 100 is used.

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

In the example shown in FIG. 23, the after-mist mode is controlled to spray mist of the sterilized water only into the toilet 800. In other words, the first mode described above is executed each time. 23 also illustrates operation in the manual mist mode. In this example, in the manual mist mode, as in the example described with reference to FIGS. 9 and 20, mist of the sterilized water is sprayed into the toilet 800 and the seat 200.

When the user leaves the bathroom and the detection sensor 402 detects the user, and the user does not detect the user (step S301: Yes), the control device 405 starts the after-mist mode. The mist of the sterilized water is sprayed only in the toilet 800 (step S302), and the after-mist mode ends. In the after-mist mode, it is possible to suppress the occurrence of visible stains due to the scale component in a short period of time by not spraying the sanitizing water to the seating portion 200 or the like.

When the user does not leave the bathroom (step S301: No), if the user operates the manual operation unit 500 (step S303: Yes), the control device 405 starts the manual mist mode. Mist of the sterilized water is sprayed on the toilet 800 and the seating portion 200 (step S304), and the manual mist mode is ended. In addition, when the user does not operate the manual operation unit 500 (step S303: No), the manual mist mode is not executed.

Since the manual mist mode is a mode in which the user wipes with paper after mist, the execution frequency of the manual mist mode tends to be lower than that of the aftermist mode. Therefore, as shown in the example shown in Fig. 23, in the after-mist mode, the mist is sprayed only in the toilet 800, and in the manual mist mode, the mist is sprayed into the toilet 800 and the seating portion 200 in the toilet seat ( It is possible to lower the frequency of mist attachment to 200). Thereby, the period until the scale component which precipitates by evaporation of the adhered mist grows to visible scale contamination can be lengthened. Therefore, it is possible to suppress the occurrence of stains that can be visually observed in a short period of time in an area in which cleaning water such as the seating portion 200 does not flow.

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

As shown in Fig. 24 (a), in the pre-mist mode, the mist of tap water or sanitized water is sprayed on the washing area 801A and the non-cleaning area 801B, and the tap water or the sanitizing water is cleaned on the cleaning area 801A and non-cleaning. The water droplets WD1 or the water film WF1 are formed by staying in the region 801B. For example, the control device 405 retains the mist that has been started by reducing the particle size of the mist or controlling the amount of mist in the pre-mist mode. In addition, it is not necessary for all the mists in the launched mist to stay, and it is only necessary to stay in such a manner that it is possible to suppress the adhesion or sticking of dirt to the cleaning area 801A and the non-cleaning area 801B.

Thereafter, when the user leaves the bathroom, the aftermist mode is executed. As shown in Fig. 24 (b), in the after-mist mode, the mist of the sterilized water is launched into the water droplets WD1 or water film WF1 formed in the non-cleaning region 801B in the pre-mist mode. Thereby, the after-mist mode washes the water droplet WD1 or the water film WD1 by increasing the volume of the water droplet WD1 or the water film WF1. That is, the water volume WD1 or the water film WF1 formed in the non-clean area 801B flows down to the cleaning area 801A by increasing the volume and increasing its own weight. In addition, in the pre-mist mode, even if not all of the mist in the mist that has settled on the water droplet WD1 or the water film WF1 formed in the non-cleaning region 801B is washed, most of the mist is washed to prevent contamination of visible water. Can be delayed.

In the pre-mist mode, the sprayed mist stays in the cleaning area 801A and the non-cleaning area 801B, and, for example, water droplets WD1 or water film WF1 do not flow until after-mist mode is executed. As a result, it is possible to more suppress the adhesion and fixation of dirt compared to the case where only the bowl portion 801 is wet. In addition, in the after-mist mode, the mist of the sterilized water sprayed from the spraying device 481 starts the non-cleaning area 801B. Thereby, generation | occurrence | production of the bacteria and contamination by the dirt which was not washed with washing water can be suppressed.

In addition, when the water droplet WD1 or the water film WF1 formed by the pre-mist mode remains attached to the non-cleaning region 801B, the scale precipitates by evaporation of the water droplet WD1 or the water film WF1, and Occasional contamination may occur in the cleaning region 801B. On the other hand, by washing the water droplets WD1 or water film WF1 formed in the non-cleaning area 801B by the after-mist mode, the water droplets WD1 or water film WF1 are suppressed from remaining in the non-cleaning area 801B. can do. Thereby, generation | occurrence | production of the stain | pollution | contamination can be suppressed. Therefore, it is possible to suppress the occurrence of stains and stains that can be visually observed in a short period of time in the non-cleaning area 801B while suppressing the occurrence of bacteria or contamination in a wide range of the toilet 800 including the non-cleaning area 801B. have.

25A and 25B are cross-sectional views illustrating another operation in the pre-mist mode of the toilet seat apparatus according to the embodiment.

In this example, the premist mode has a first process shown in Fig. 25 (a) and a second process shown in Fig. 25 (b).

As shown in FIG. 25 (a), the first process emits mist in the non-cleaned area 801B, and forms a water droplet WD1 or a water film WF1 in the non-cleaned area 801B. Further, in the first step, mist may also be formed in the cleaning region 801A to form a water droplet or a water film.

As shown in FIG. 25 (b), in the second process, mist is sprayed on the water droplets WD1 or water film WF1 formed in the non-cleaning region 801B in the first process. Thereby, the 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, the water volume WD1 or the water film WF1 formed in the non-clean area 801B flows down to the cleaning area 801A by increasing the volume and increasing its own weight. In the pre-mist 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 mis-entry room or the like and the first process in the pre-mist mode is executed, the second process is executed to perform the water drop (WD1) formed in the non-clean area 801B, or The water film WF1 is flowed down.

By washing the water droplets WD1 or water film WF1 formed in the non-cleaning area 801B by the first process by the second process, the water droplets WD1 or water film WF1 remain in the non-cleaning area 801B. Can be suppressed. Thereby, generation | occurrence | production of the stain | pollution | contamination can be suppressed. Therefore, it is possible to suppress the occurrence of stains and stains that can be visually observed in a short period of time in the non-cleaning area 801B while suppressing the occurrence of bacteria or contamination in a wide range of the toilet 800 including the non-cleaning area 801B. have.

In addition, in the pre-mist mode, if the mist is sprayed so that the launched mist flows immediately, there is a fear that the mist may splash out of the bowl portion 801 and scatter out of the toilet 800 because the mist has a large particle size or flow rate. On the other hand, in this example, after forming the water droplet WD1 or the water film WF1 by the first process, the water droplet WD1 or the water film is increased by increasing the volume of the water droplet WD1 or the water film WF1 by the second process. (WF1) is being dropped. Thereby, it can suppress that a mist scatters out of a toilet.

26 (a) and 26 (b) are plan views illustrating toilets and toilet seats according to an embodiment.

26A shows the back surface 204 side of the seating portion 200. The toilet seat leg portion 210 is provided on the back surface 204 of the seating portion 200. The toilet seat leg portion 210 is installed to protrude from the rear surface 204, and the seating portion 200 contacts the upper surface 806 of the rim of the toilet 800 in a closed state. In this example, four toilet seat legs 210 are provided in total, but the number or shape of the toilet seat legs 210 is arbitrary.

As shown in FIG. 26 (b), the upper rim 806 of the toilet 800 has an area 810 in which the toilet seat leg 210 contacts the seat 200 when the toilet seat 200 is closed.

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

So, in one embodiment of the toilet seat apparatus 100, the after-mist mode or the manual-mist mode has the first process and the second process described below.

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

Fig. 27 (a) shows the first process, and Fig. 27 (b) shows the second process. As shown in Fig. 27 (a), in the first step, the control device 405 controls the motor 511 for the toilet seat or the motor 512 for the toilet seat to open the seating portion 200 and the toilet seat cover 300. Let it be closed (fully closed). When the toilet seat cover 300 is closed, the first process sprays the mist of the sterilizing water onto the rim top surface 806 and the seating portion 200. In the first process, since the toilet lid 300 is closed, a lot of mist is applied to the rim upper surface 806 or the seating portion 200 while suppressing the scattering of mist on the outside of the toilet 800 and the toilet seat apparatus 100. You can spray.

As shown in FIG. 27 (b), in the second step, the control device 405 controls the motor 511 for the toilet seat or the motor 512 for the toilet seat to open the seating portion 200 and the toilet seat cover 300. Leave it open. In the state in which the seating part 200 and the toilet seat cover 300 are opened, the second process sprays the mist of the sterilizing water onto the upper surface 806 and the seating part 200 of the rim. Thereby, the 2nd process sprays the mist of the sterilized water to the area | region 810 which the toilet seat leg part 210 of the upper surface 806 of the rim contacts. In the second step, since the seating portion 200 is in an open state, mist can be also applied to the toilet seat leg portion 210 or the region 810 of the upper surface of the rim 806. In addition, mist is likely to start on the outer peripheral portion 806e of the upper surface of the rim 806 and the outer peripheral portion 204e of the seating portion 200.

The control device 405 executes the second process after performing the first process, for example, in the one-time aftermist mode and the 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 upper rim 806 contacts the rest of the toilet 800 and the toilet seat apparatus 100 while suppressing mist scattering by the first and second processes described above. It is possible to suppress the occurrence of bacteria or contamination by launching many mists in a wide range including.

In addition, in the second process in the after mist mode or the manual mist mode, the range in which the seating portion 200 and the toilet seat cover 300 are opened is assumed to include a semi-open state as well as a fully open state. The fully opened 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 degree of opening is smaller than the fully open state. That is, the half-open state is a state between the fully open state and the fully closed state, and the degree of opening is not limited to being half of the fully open state.

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

In addition, for example, in the first process, the control device 405 has a total amount (ml) of mist of the sterilizing water sprayed on the upper side of the rim in the first step, and the sterilization sprayed on the upper side of the rim in the second step (806). The spraying device 481 is controlled to be larger than the total amount (ml) of the number of mists. For example, the total amount of mist of the sterilizing water that lands on the upper surface of the rim in the first step is greater than the total amount of mist of the sanitizing water that lands on the upper surface of the rim in the second step. In the first step, the occurrence of bacteria and contamination on the rim top surface 806 can be further suppressed by the fact that a large number of mists of the disinfecting water enter the rim top surface 806. At this time, in the first step, the toilet lid 300 is closed, so 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 second process in which the toilet seat cover 300 is opened together with the seating portion 200, the mist tends to scatter out of the toilet bowl 800 and the toilet seat apparatus 100 in comparison with the first step. Thus, in the second step, by spraying a relatively small amount of mist on the upper surface of the rim, it is possible to suppress the mist from scattering outside the toilet 800 and the toilet seat apparatus 100.

Specifically, for example, in the first step, the control device 405 sprays the mist of the sterilized water on the rim top surface 806 side in the first step, and the mist of the sterilized water on the rim top surface 806 side in the second step. The spraying device 481 is controlled to be longer than the time for spraying. That is, for example, the time at which the first process is executed is longer than the time at which the second process is executed. Thereby, the total amount of mist sprayed on the rim upper surface 806 side in the first step can be made larger than the total amount of mist sprayed on the rim upper surface 806 side in the second step.

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

In the second process in the after mist mode or the manual mist mode, the control device 405 sprays the sterilized water mist on the upper surface of the rim 806 and the motor 511 for the toilet seat and the motor 512 for the toilet seat cover. By controlling the, you may move at least one of the seating part 200 and the toilet seat cover 300. 28 (a) shows a state in which the seating portion 200 is moved in the opening direction in the second step. When the seating part 200 is rotated from the bottom to the top as shown by the arrow A7, air flow f2 (rising air flow) is generated in the vicinity of the upper surface of the rim 806. By sterilizing the mist of the sterilizing water, the mist of the sterilizing water can be launched in a wider range of the upper surface 806 of the rim by riding the air flow f2.

28 (b) shows a state in which the seating portion 200 is moved in the closing direction in the second step. When the seating part 200 is rotated from the upper side to the lower side as shown by the arrow A8, air flow f3 is generated in the vicinity of the upper surface of the rim 806. Thereby, the mist in the vicinity of the upper surface of the rim 806 is diffused, and the mist of the sterilized water can be spread over a wider range of the upper surface of the rim 806.

In the example shown in FIGS. 28 (a) and 28 (b), the control device 405 moves the seating portion 200, but the toilet cover 300 may be moved similarly. In the second step, the control device 405 may move the other by stopping one of the seating portion 200 and the toilet lid 300, or both.

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

29, the toilet 800 is shown by a solid line. Further, the casing 400 of the toilet seat apparatus 100 mounted on the upper surface of the toilet 800, that is, the upper surface of the rim 806, is indicated by a broken line.

The casing 400 (body part) of the toilet seat apparatus 100 is mounted on the rear part of the upper surface 806 of the rim. That is, the upper surface of the rim 806 has a non-loading portion 806f on which the casing 400 is not loaded, and a loading portion 806r on which the casing 400 is loaded. The loading portion 806r is located behind the non-loading portion 806f. The loading portion 806r refers to a portion of the upper surface 806 of the rim that overlaps the casing 400 in the vertical direction, and the loading portion 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 loading portion 806r of the upper rim 806. The packing 490 is disposed in the front portion of the loading portion 806r according to the shape of the casing 400. Thereby, it is possible to prevent the washing water, mist, 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 loading portion 806r and the casing 400. For example, in the after mist mode or the manual mist mode, when the mist of the sterilized water is sprayed not only in the bowl portion 801 but also on the upper surface 806 of the rim, the mist of the sterilized water may enter the gap SP. have. Since the gap SP is a part that is difficult for the user to see, the mist that has started on the loading portion 806r entering the gap SP becomes a large water droplet (WD2) or a water film (WF2) unintentionally and leaks out of the toilet (800). May occur.

Thus, in the after-mist mode or the manual mist mode, the spraying device 481 has an average amount of water per unit area of the number of bacteria disinfecting the non-loading unit 806f, and an average amount of water per unit area of the number of bacteria dissipating the loading unit 806r. Disinfect water is sprayed so that it becomes larger. It is preferable that the spraying device 481 starts sterilizing water to the non-loading part 806f and does not start sterilizing water to the loading part 806r.

The generation of bacteria and contamination in the non-loading portion 806f can be suppressed by embedding a larger number of disinfecting water into 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 compared to the loading portion 806r, and is also a portion that is easy to see and easy to wipe. For this reason, even if the bacteria removal water starts on the non-loading portion 806f of the upper surface of the rim 806f, it is unlikely that the bacteria removal water aggregates in the non-loading portion 806f and becomes large water droplets or water film and falls out of the toilet 800. . In addition, the relatively small number of bacteria to be settled on the loading portion 806r makes it possible to suppress the disinfection water from agglomerating in the loading portion 806r to become a large water droplet or a water film, and to fall out of the toilet 800. Therefore, when mist of the sterilized water is sprayed on the upper surface 806 of the toilet 800, water leakage out of the toilet 800 can be suppressed.

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

First, after performing the after mist mode or the manual mist mode, the mist started on the non-loading portion 806f is wiped off with a towel. The average amount of water per unit area of sanitized water that has been launched into the unloading section 806f by dividing the area between the weight of the kim towel before wiping off the mist and the weight after wiping off the mist is the unloading section 806f. Is calculated.

Similarly, after the after-mist mode or the manual-mist mode is executed, the mist starting on the loading portion 806r on the front side of the packing 490 is wiped off with a kim towel. By dividing the difference between the weight of the Kim towel before wiping off the mist and the weight after wiping off the mist to the area of the loading section 806r, the average amount of water discharged per unit area of the sterilizing water launched into the loading section 806r is calculated. .

30 is a cross-sectional view illustrating the operation of the toilet seat apparatus according to the embodiment in an after mist mode or a manual mist mode.

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

In this example, the spraying device 481 has a first water jetting section 51 and a second water jetting section 52. A nozzle capable of ejecting (spraying) tap water or sanitized water is used, for example, in the first jetting section 51. The disk 481b described above is used, for example, in the second jetting portion 52.

The flow path 113 that guides water to the spraying device 481 is divided into a flow path that supplies water to the first water jetting unit 51 and a flow path that supplies water to the second water jetting unit 52. The water supply to each water jetting section is controlled by the control device 405. The first water jetting section 51 and the second water jetting section 52, for example, simultaneously eject (spray) the sterilizing water.

Fig. 31 (a) illustrates the operation of the second jetting section 52 in the after mist mode or the manual mist mode. The second water jetting portion 52 starts sterilizing water to the non-loading portion 806f of the upper surface 806 of the rim. In addition, the second water jetting section 52 starts sterilizing water on the front side of the second water jetting section 52 in the bowl section 801.

For example, the second water jetting portion 52 sprays the mist of the sterilizing water in the forward and downward directions. A part of the sprayed mist rises upward from the upper surface of the rim by riding the upward air flow U1 formed by the blowing device 513. As a result, the mist of the sterilized water is settled on the non-loading portion 806f, the seating portion 200, and the toilet lid 300.

Fig. 31 (b) illustrates the operation of the first jetting section 51 in the after mist mode or the manual mist mode. The first water jetting section 51 ejects (sprays) the sterilizing water backward and downward, and starts sterilizing water on the rear side (loading section 806r) than the first water jetting section 51 in the bowl section 801. Order.

The spraying device 481 is installed inside or below the casing 400. In addition, the sanitizing water sprayed from the spraying device 481 gradually falls by its own weight. Therefore, it is preferable to spray the sterilized water from a high position in order to start the sterilized water to the non-loading portion 806f. Thus, as shown in FIG. 30, the second water jetting section 52 is disposed above the first water jetting section 51 (nozzle jetting port). Thereby, the sterilizing water can be started to be reliably attached to the unloading portion 806f. On the other hand, it is preferable to spray (spray) the sterilizing water from a low position in order to suppress the watering of the sterilizing water to the loading portion 806r. 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 sterilizing water starts to the loading part 806r.

In addition, the second water jetting portion 52 is desired to be clean in order to start the sterilizing water to the non-loading portion 806f of the upper surface 806 of the rim, which the user may touch. Thus, the second water jetting portion 52 is disposed inside the casing 400. Further, the second water jetting portion 52 (disk 481b) is positioned above the rim upper surface 806. Thereby, it is possible to prevent dirt from adhering to the second water jetting section 52 and to ensure the cleanliness of the second water jetting section 52.

On the other hand, the first water jetting section 51 has a problem of cleanliness compared to the second water jetting section 52 in order to start the sterilizing water to the loading section 806r in the bowl section 801, which is unlikely to be touched by the user. It is difficult to be. Thus, the first water jetting portion 51 is arranged to protrude downward from the casing 400. For example, the first water jetting part 51 (nozzle water jetting port) is located below the upper surface 806 of the rim. Thereby, the 1st water jetting part 51 can be arrange | positioned at a low position, and it can suppress more that the sterilizing water starts to the loading part 806r.

In addition, the spraying device 481 (the second water jetting portion 52, when viewed from the upper surface, increases at least a part of the sterilizing water sprayed on the loading portion 806r side (rear side) than the spraying device 481 upward airflow U1 On the other hand, the spraying device 481 (first jetting part 51) is sprayed on the non-loading part 806f (front side) than the spraying device 481 when viewed from the top. At least a portion of the sanitizing water is formed to have a size in which the rising air stream U1 is burned.

Specifically, the spraying device 481 has a shower shape, a membrane shape, or a mist shape having a first particle diameter as the number of germs sprayed on the loading portion 806r side than the spraying device 481 when viewed from the top. In addition, when viewed from the top, the spraying device 481 has a mist shape having a second particle diameter smaller than the first particle diameter of the number of bacteria discharging to the non-loading portion 806f side than the spraying device 481.

As a result, the number of bacteria disinfecting water sprayed from the spraying device 481 to the non-loading portion 806f is easier to catch an upward air flow than the number of bacteria discharging to the loading portion 806r, so that the number of bacteria disinfecting in the non-loading portion 806f is high. Can be launched. On the contrary, the sterilizing water sprayed from the spraying device 481 to the loading part 806r side is less likely to catch an upward airflow than the sterilizing water sprayed to the non-loading part 806f side, thereby preventing the sterilizing water from entering the loading part 806r. can do.

In addition, an average value or a median value of the particle size distribution of the mist can be used for comparison between the first and second particle sizes. In addition, the shower shape and the membrane shape are water shapes larger than the fine particles of the mist. The self-weight of the shower-shaped and membrane-shaped sterilizing water is larger than the self-weight of the particles of the mist having the first particle diameter. The number of bacteria in the shape of the shower may be in the form of a thread or a large particle. The shape and size of the sterilizing water sprayed on the loading portion 806r side can be adjusted by, for example, the shape of the water jetting port of the first water jetting unit 51.

In FIG. 30 and FIG. 31, the case where two water jetting portions are provided has been described. However, the number of water jetting portions may be one or three or more. By appropriately changing the spraying direction, the spraying range, and the particle size of the mist, it is possible to suppress the disinfection water from entering the loading section 806r while starting a large amount of disinfection water to the non-loading section 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 manual operation unit 500 is continuously operated for a short time, and the manual mist mode is continuously executed for a short time, the seating unit 200 may be excessively wet. As a result, there is a fear that a user who comes into contact with the mist that has started on the seating unit 200 feels discomfort, or that the mist that has started off may fall out of the toilet 800.

Thus, in the example shown in Fig. 32, the control device 405 has a continuous manual mist inhibiting mode. In the continuous manual mist prohibition mode, when the manual operation unit 500 is operated again within a predetermined time after execution of the manual mist mode (before the predetermined time elapses from the end of the manual mist mode), a predetermined time from the end of the manual mist mode It is forbidden to run the manual mist mode again until it has elapsed. In addition, the continuous manual mist prohibition mode prohibits the manual mist mode from being executed 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 the user inputs the start of the manual mist mode by operating the manual operation unit 500 (step S401: Yes), the control device 405 is set from the end of the previous manual mist mode. It is determined whether the time has elapsed (step S402). When 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 from the end of the previous manual mist mode (step S402: No), and the wiping operation described later is not detected (step S404: No), The control device 405 enters a continuous manual mist inhibiting mode. That is, the manual mist mode is not executed.

In this way, even if the manual operation unit 500 is operated within a predetermined time after or during the execution of the manual mist mode, the manual mist mode is not executed again by the continuous manual mist inhibiting mode. Thereby, even if manual operation of spraying a mist in a short period of time is continuously performed, it is possible to suppress the excessive amount of mist from entering the seating portion 200. It is possible to suppress that many of the mists are launched into the seating portion 200 and the user feels uncomfortable, and that the mist that is launched into the seating portion 200 falls out of the toilet 800.

In addition, the predetermined time in step S402 is set to a time, for example, when the manual mist mode is executed again, and the mist that is started does not fall out of the toilet 800 even if the mist is further settled in the seating unit 200. . The predetermined time is appropriately determined according to the amount of mist sprayed in the manual mist mode, and is, for example, 10 seconds or more and 5 minutes or less. The predetermined time may be a time during which the mist initiated on the seating unit 200 evaporates in the previous manual mist mode.

The user can remove the bacteria or contamination attached to the seating portion 200 by wiping the mist that has landed on the seating portion 200 by a manual mist mode using a toilet paper or the like. When the user still wipes almost all of the mist that has settled on the seating part 200, if the still remains on the seating part 200, the user may re-execute the manual mist mode and may want to 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 that releases the execution of the continuous manual mist inhibiting mode before a predetermined time elapses from the end of the manual mist mode, and makes the manual mist mode executable again. Thereby, it is possible to perform the manual mist mode 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 motion detection means for detecting that the user has performed a wiping motion on the seat 200. The control device 405 executes a manual mist release mode based on the detection information of the wiping motion detection means.

As shown in Fig. 32, when it is detected that the user has performed the wipe operation by the wipe operation detection means (step S404: Yes), the manual mist release 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 motion detection means, for example, a 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 seating detection sensor 404, the wiping operation of the seating portion by the user can be more reliably detected. For example, when the seating detection sensor 404 is a sensor capable of detecting the load applied to the seating unit 200, the user wipes the action based on the size of the load applied to the seating unit 200 or the time the load was applied. You can detect that you have done In addition, for example, when the seating detection sensor 404 is a sensor capable of acquiring a distance to the human body, it is possible to detect that the user has performed a wiping operation based on a change in the distance.

In addition, when the user does not spray the mist because the manual mist mode is not executed by the continuous manual mist prohibition mode even though the user has operated the manual manipulation unit 500 to execute the manual mist mode, the user may use the toilet 100 There is a possibility of misunderstanding that it is broken. Therefore, when the user's wiping operation is not detected (step S404: No), the control device 405 notifies by means of the notification means that the continuous manual mist inhibiting mode has been executed (step S405). This can prevent the user from being mistaken. Any means capable of notifying by means of sound or light can be used as the means for notifying. For example, as a notification means, a speaker, an LED, or a liquid crystal display can be suitably installed in the manual operation unit 500 or the casing 400.

In addition, the toilet seat apparatus 100 has an operation unit (for example, a manual operation unit 500) for inputting that the user has performed the wiping operation on the seating unit 200. The control device 405 executes a manual mist release mode based on 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 when the control device 405 receives the input information, the manual mist release mode is executed. (Step S406: Yes). Thereby, the manual mist mode can be executed again, and the manual mist mode is executed (step S403). By using such an operation unit, it is possible to more reliably detect the wiping operation of the seating unit 200 by the user, thereby improving convenience in use. In addition, the user may operate the operation unit as necessary without performing a wiping operation.

When the user does not operate the operation unit for inputting the wiping operation to the seating unit 200 (step S406: No), the execution of the manual mist mode is prohibited until a predetermined time elapses from the end of the manual mist mode. 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 device 405 has two types of manual mist modes: a first manual mist mode and a second manual mist mode. The total amount of mist of the sterilizing water sprayed in the second manual mist mode is less than the total amount of mist of the sterilizing water sprayed in the first manual mist mode. For example, the spray time of the second manual mist mode is shorter than the spray time of the first manual mist mode.

The first manual mist mode is an operation mode in which the user controls the spraying device 481 and sprays the mist of the sterilizing water onto the seating unit 200 when the manual operating unit 500 is operated.

On the other hand, 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 spraying device ( 481) to control the mist of the sterilized water is sprayed on the seat 200. In addition, 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 spraying device 481 is controlled to spray the mist of the sterilizing water onto the seating unit 200.

In other words, it is forbidden to execute the first manual mist mode again until a predetermined time elapses 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 the user inputs the start of the manual mist mode by operating the manual operation unit 500 (step S501: Yes), the control device 405 ends the previous first manual mist mode. Then, it is judged whether or not a predetermined time has elapsed (step S502). When 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 the execution of the first manual mist mode or the end of the previous first manual mist mode (step S502: No), and the wiping operation is not detected (step S504: No) ), The control device 405 executes the second manual mist mode.

 As described above, when the manual operation unit 500 is operated during or after the first manual mist mode is executed, the second manual mist mode in which the mist is less sprayed than the first manual mist mode is executed. Thereby, even if manual operation of spraying a mist is continuously performed, it is possible to suppress the excessive number of mists from entering the seating portion 200. It is possible to suppress that many of the mists are launched into the seating portion 200 and the user feels uncomfortable, and that the mist that is launched into the seating portion 200 falls out of the toilet 800.

In addition, the predetermined time in step S502 is, for example, the time when the first manual mist mode is executed again and the mist is not flowed out of the toilet 800 even if the mist is further settled in the seating unit 200. Is set to The predetermined time is appropriately determined according to the amount of mist to be sprayed, and is, for example, 10 seconds or more and 5 minutes or less. The predetermined time may be a time during which the mist that has started on the seating unit 200 evaporates in the first manual mist mode.

When the user wants to further wipe out the contamination remaining on the seating unit 200 after the execution of the first manual mist mode, if the amount of mist spray is small by the second manual mist mode, it is difficult to wipe off the contamination.

Thus, the control device 405 has a manual mist release mode that enables the first manual mist mode again before a predetermined time has elapsed from the end of the first manual mist mode. By this, even if a predetermined time has not elapsed from the previous first manual mist mode, the first manual mist mode can be executed again, thereby improving convenience in use.

As shown in Fig. 33, when it is detected that the user has performed the wipe operation by the wipe operation detection means (step S504: Yes), the manual mist release mode is executed. That is, the first manual mist mode is enabled again, and the first manual mist mode is executed (step S503).

In addition, when the user operates the manual operation unit 500, the first manual mist mode is not executed, the second manual mist mode is executed, and if the mist spray amount is small, the user may misunderstand that the toilet seat apparatus 100 is broken. I have a concern. Therefore, when the user's wiping operation is not detected (step S504: No), the control device 405 notifies by means of the notification means that the second manual mist mode has been executed (step S505). This can prevent the user from being mistaken.

Further, when the manipulation unit for inputting that the user has performed the wiping operation with respect to 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 release mode is executed (step S506: Yes). Thereby, the execution of the first manual mist mode is enabled again, and the first manual mist mode is executed (step S503).

When the user does not operate the operation of inputting the wiped operation to 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 a method for measuring a particle size according to the embodiment.

The laser diffraction method is used to measure the particle size. When the fine particles are irradiated with laser, diffracted scattered light is generated from the fine particles in various directions. The intensity of the 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 size of the fine particles. The particle size can be calculated by detecting the light intensity distribution pattern using the correlation between the particle size of the fine particles and the light intensity distribution pattern.

34 (a) and 34 (b), the particle size measuring device 600 has a light emitting portion 601 and a light receiving portion 602. The light-receiving unit 602 is installed so as to be capable of receiving the laser emitted by the light-emitting unit 601. In the measurement of the particle size, 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 diffracted scattered light generated by laser irradiation. Thereby, a light intensity distribution pattern can be detected. Aerotrac LDSA-3500A (manufactured by MicrorotracBEL Corp.) can be used as the measuring device.
