Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each drawing, the same constituent elements are denoted by the same reference signs, and detailed descriptions are omitted as appropriate. FIG. 1 is a perspective view illustrating a toilet device of an embodiment. 2 is a cross-sectional view illustrating a part of the toilet device of the embodiment.

The toilet device 10 shown in FIG. 1 includes a sitting toilet (hereinafter simply referred to as “toilet” for convenience of description) 800 and a toilet seat device 100. The toilet 800 has a concave bowl portion 801 that receives dirt. The toilet seat device 100 is provided on the upper part of the toilet 800.

The toilet seat device 100 has a housing 400, a toilet seat 200 for a user to sit on, and a toilet lid 300. The toilet seat 200 and the toilet lid 300 are pivotally supported so as to be openable and closable with respect to the housing 400. The state of FIG. 1 is a state in which the toilet seat 200 is closed (a state of being lowered), and a state in which the toilet cover 300 is open (a state of being lifted). The toilet cover 300 covers the seat surface of the toilet seat 200 from above in a closed state.

Inside the casing 400, a body washing function part and the like for washing a human body part ("buttocks" and the like) of the user seated on the toilet seat 200 are built. In addition, for example, the housing 400 is provided with a seating sensor 404 that detects that the user is seated on the toilet seat 200. When the seating sensor 404 detects a user seated in the toilet seat 200, if the user operates the manual operation unit 500 such as a remote controller, for example, the cleaning nozzle (hereinafter abbreviated for convenience of explanation) can be used. ("Nozzle") 473 enters the bowl 801 of the toilet 800. In addition, the toilet seat device 100 shown in FIG. 1 shows a state where the nozzle 473 enters the bowl 801.

One or more water discharge ports 474 are provided at the front end of the nozzle 473. Accordingly, the nozzle 473 sprays water from the water discharge port 474 provided at the front end portion thereof, so that it is possible to clean the “buttocks” of the user seated in the toilet seat 200.

In addition, in the specification of this application, "upper", "lower", "front", "rear", "left side", and "right side" are seated from the toilet cover 300 with the back toward the open The direction in which the user of the toilet seat 200 observes.

As shown in FIG. 2, the toilet 800 has a bowl edge portion 805 provided above the bowl portion 801. The rim portion 805 is an annular portion that forms the upper edge of the toilet 800. In the bowl 801, stored water 801w is accumulated. For example, if the user performs a toilet cleaning operation by using a switch provided in a remote control or the like, or if the user stands up from the toilet seat 200, toilet cleaning is performed (the dirt in the bowl 801 is discharged and the bowl 801 is cleaned. Surface action). During toilet cleaning, wash water is supplied into the bowl 801. For example, in the example of FIG. 2, the washing water is discharged from the basin water supply port 811 along the upper edge of the toilet 800.

The rim portion 805 has an upper surface 806 and an inner wall surface 807. The upper surface 806 is a surface facing the back surface 204 of the toilet seat 200 that is closed. The inner wall surface 807 is a portion of the inner wall of the toilet 800 (the wall surface opposite to the central side surface of the bowl portion 801) that is higher than the portion where the washing water for washing the toilet flows. That is, in the specification of the present application, the inner wall surface 807 of the rim portion 805 refers to a non-cleaning portion during toilet cleaning. In the example of FIG. 2, the inner wall surface 807 includes a vertical surface located above the bent portion 805B bent in the shape of a shelf.

That is, the nozzle motor 476 advances and retreats the nozzle 473 based on an instruction from the control device 405. The nozzle 473 is stored in the housing 400 when not in use. The nozzle 473 discharges water from the water discharge port 474 in a state where it enters forward from the housing 400 and cleans parts of the human body.

The nozzle cleaning chamber 478 cleans the outer peripheral surface (main body) of the nozzle 473 by spraying sterilized water or tap water from a water discharge port provided therein.

The spray device 481 forms tap water or the sterilized water generated by the sterilizing device 450 into a water mist. The spray device 481 sprays water mist M (water mist of sterilized water or water mist of tap water) to the bowl portion 801, the bowl edge portion 805, and the toilet seat 200. In other words, the spray device 481 applies the water mist of the sterilized water or the water mist of the tap water to the bowl portion 801, the bowl edge portion 805, and the toilet seat 200. In addition, in the specification of the present application, "watering" means that water (sterilized water or tap water) adheres to the surface of an object. Especially in the case of "direct water", it means that water (sterile water or particles p of tap water) reaches the surface of the object from the air.

In addition, inside the housing 400, a toilet seat motor 511 (rotating device), a toilet cover motor 512 (rotating device), an air blowing device 513, and a warm air heater 514 are provided. The toilet seat motor 511 electrically turns the toilet seat 200 to open and close based on an instruction from the control device 405. The toilet cover motor 512 electrically rotates the toilet cover 300 to open and close based on an instruction from the control device 405.

The air blowing device 513 is, for example, a fan provided inside the casing 400. The air blowing device 513 performs an operation based on an instruction from the control device 405. For example, as the motor of the air blowing device 513 rotates, the blades rotate. As a result, the air blowing device 513 can blow air into the toilet 800 (for example, inside the bowl 801). In addition, the air blowing device 513 may blow air locally to the user seated on the toilet seat 200. The warm air heater 514 heats the air sent out of the housing 400 by the air blowing device 513. By this, the warm air is sent toward the user's part, and the part can be dried.

The toilet seat heater 515 (drying device) is provided inside the toilet seat 200, for example. The toilet seat heater 515 has, for example, a ring-shaped metal member provided around the opening 200 a formed in the center of the toilet seat 200. By energizing the toilet seat heater 515 based on an instruction from the control device 405, the toilet seat heater 515 heats the toilet seat 200. As the toilet seat heater 515, for example, a tube heater, a sheath heater, a halogen heater, a carbon heater, or the like may be used. The metal member is composed of, for example, aluminum, copper, or the like. In addition, the shape of the metal member can be various shapes such as a sheet shape, a wire shape, and a mesh shape.

The control device 405 uses a circuit that receives power supply from a power supply circuit (not shown). For example, the control device 405 includes an integrated circuit such as a microcomputer. The control device 405 controls the solenoid valve 431 and the sterilization device 450 based on the detection information of the sensor 402 (for example, the human body sensor 403 or the seating sensor 404) that detects the user or the operation information of the manual operation unit 500. , The switching valve 472, the nozzle motor 476, the air supply device 513, the heater heater 514, the toilet seat heater 515, the toilet seat motor 511 and the toilet lid motor 512 are 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 controller having a switch, a button, or the like. When the user operates the manual operation unit 500, operation information (signal) indicating the spray of the sterilized water is transmitted to the control device 405. The control device 405 controls the sterilization device 450 and the spray 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, and the like for the user to operate each function of the toilet seat device 100, not just a spray of sterilized 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 device 100 based on the operation information.

The seating sensor 404 can detect whether the user is seated toward the toilet seat 200. The seating sensor 404 detects the user's seating and leaving. The seating sensor 404 can use a microwave sensor, a distance measuring sensor (infrared projection sensor), an ultrasonic sensor, a touch switch, a capacitance switch (touch sensor), or a deformation sensor. In this example, the seating sensor 404 uses a distance measuring sensor provided in the housing 400.

In addition, when a touch sensor such as a touch switch, an electrostatic sensor, and a deformation sensor is used, these touch sensors are provided on the toilet seat 200. If the user is seated on the toilet seat 200, the touch switch is depressed due to the user's weight. Or, the user is in contact with the static sensor. Alternatively, pressure is applied to the deformation sensor due to the weight of the user. Based on the electrical signals from these sensors, the user's seating can be detected.

The human body sensor 403 can detect a user who is located in front of the toilet 800, that is, a user who is present at a position away from the toilet seat 200 forward. That is, the human body sensor 403 can detect a user who enters the toilet and approaches the toilet seat 200. As such a human body sensor, for example, a focus sensor, a microwave sensor, an ultrasonic sensor, or a distance measuring sensor (infrared projection sensor) can be used. In this example, the human body sensor 403 uses a pyroelectric sensor provided in the housing. In addition, the human body sensor 403 may detect a user who has just opened the door of the toilet and a user who is about to enter the toilet, that is, a user who is about to enter the toilet and exists in front of the door. For example, when a microwave sensor is used, the presence of the user can be detected through the door of the toilet.

The control device 405 receives the detection information of the human body sensor 403 (signal indicating whether the user is present), the detection information of the seating sensor 404 (signal indicating whether the user is seated), and based on the received detection information, The operation of each part of the toilet seat device 100 is controlled.

The control device 405 can execute three spray modes: an after-commode spray mode, a pre-appliance spray mode, and a manual spray mode. The post-toilet spray mode is, for example, an operation mode in which a user automatically sprays water mist of sterilized water based on the detection information of the sensor 402 after the user uses the flushing device 10. The pre-detox spray mode is, for example, an operation mode in which a water mist of sterilized water or tap water is automatically sprayed based on the detection information of the sensor 402 before the user uses the flushing device 10. The manual spray mode is an operation mode for spraying water mist of sterilized water based on operation information of the manual operation unit 500.

4(a) to 4(e) illustrate a plan view and a perspective view of the toilet device of the embodiment. FIG. 4(a) shows a state in which a part of the toilet device 10 is viewed from the front. As shown in FIG. 4( a ), the spray device 481, the nozzle shutter 479, and the air supply shutter 516 are located in the upper rear portion of the bowl 801 in the state where the toilet seat device 100 is installed above the toilet 800.

FIG. 4(b) shows an enlarged part of FIG. 4(a). In addition, in FIG. 4( b ), in order to facilitate the observation, a part of the housing 400 located in front of the spray device 481 is omitted. The nozzle shutter 479 is pivotally supported relative to the housing 400. The nozzle 473 is located behind the nozzle shutter 479 in a state of retracting into the inside of the housing 400. When cleaning the body part, the nozzle 473 abuts the nozzle shutter 479, and the nozzle shutter 479 is opened by rotating the nozzle shutter 479, and then protrudes from the inside of the housing 400.

4(c) to 4(e) are enlarged perspective views showing the periphery of the spray device 481, the nozzle baffle 479, and the air supply baffle 516. The air baffle 516 is pivotally supported relative to the housing 400. Behind the air baffle 516, an air blowing device 513 is arranged. The air supply baffle 516 covers the opening 516a of the housing 400. The air sent from the blower 513 is sent into the toilet 800 through the opening 516a.

FIG. 4(c) shows a state in which the air blowing device 513 stops operating, and FIGS. 4(d) and 4(e) show a state in which the air blowing device 513 operates to blow air into the bowl 801. As shown in FIG. 4(c), in a state where the blowing is stopped, the blowing flap 516 is closed. As shown in FIG. 4(d), when the air blowing device 513 is operated, the air blowing shutter 516 is rotated and opened by the pressure (wind pressure) of the air sent from the air blowing device 513. As a result, for example, as in the arrow A1, the air blowing device 513 blows air from the upper back in the basin 801 to the lower front in the basin 801. In the state of FIG. 4(e), the air volume sent by the air blowing device 513 is larger than the state of FIG. 4(d) (or the wind speed is higher). In this case, the air supply damper 516 is further opened than the state of FIG. 4(d). As a result, the air blowing device 513 blows air from the upper rear part in the bowl 801 to the upper front part in the bowl 801 like an arrow A2, for example.

In this way, the direction of the wind sent from the air blowing device 513 is changed by the air blowing damper 516. In other words, the air blowing device 513 can control the air blowing direction according to the air volume (wind speed). The water mist sprayed from the spraying device 481 may also ride on the airflow generated by the air blowing from the air blowing device 513 to control the range of water sprayed by the water mist and the amount of water sprayed in each range (water in each range The amount of sterile water or tap water).

5(a) to 5(c) are perspective views illustrating another toilet device according to the embodiment. In this example, a water mist baffle 482 is provided in front of the spray device 481. The water mist baffle 482 covers at least a part of the front of the spray device 481 in a closed state. For example, the water mist shutter 482 covers the front of the disk 481b described later in FIG. 6 in the closed state.

The water mist baffle 482 is fixed with respect to the nozzle baffle 479, for example, and is linked with the nozzle baffle 479. By opening the nozzle shutter 479, the water mist shutter 482 is also opened, and by closing the nozzle shutter 479, the water mist shutter 482 is also closed.

5(b) and 5(c) show the periphery of the nozzle shutter 479 and the water mist shutter 482 in an enlarged manner. FIG. 5(b) shows a state where the nozzle 473 is retracted into the inside of the housing 400. At this time, the nozzle shutter 479 is in a closed state, which covers the front of the nozzle 473. In addition, the water mist baffle 482 is in a closed state, which covers at least a part of the front of the spray device 481.

When the spray device 481 is not used, as shown in FIG. 5( b ), the spray device 481 is hidden from the pot 801 side by the water mist baffle 482. This can prevent urine and dirt from adhering to the spray device 481.

FIG. 5(c) shows a state where the nozzle 473 is extended forward and the nozzle shutter 479 is rotated. At this time, the distance that the nozzle 473 extends forward may be shorter than the distance that extends forward when the human body is partially washed. For example, the front end of the nozzle 473 is in contact with the nozzle shutter 479. In addition, in FIG. 5(c), the water mist shutter 482 rotates together with the nozzle shutter 479 to open. A part (spray 481b) of the spray device 481 is exposed to the bowl 801 side. With this, the spray device 481 can spray water mist toward the bowl 801. In addition, as will be described later with reference to FIG. 22, for example, the spray device 481 may be arranged in the housing 400 without providing the water mist baffle 482.

6(a) to 6(c) are schematic views illustrating the spray device of the embodiment. FIG. 6(a) is a perspective view of the spray device 481, and FIG. 6(b) is a side view of the spray device 481. FIG. The spray device 481 has a motor 481a and a disk 481b connected below the motor 481a. The rotation of the motor 481a is controlled by the control device 405. When the motor 481a rotates, the rotational driving force is transmitted to the disk 481b, and the disk 481b rotates.

As shown in FIG. 6(b), water W (tap water or sterilized water generated by the sterilizing device 450) is supplied to the upper surface of the tray 481b. When the water W is supplied during the rotation of the disk 481b, the spray device 481 sprays the water W into a water mist. In addition, in this example, the disk 481b has a flat disc shape, but it is also possible to appropriately provide irregularities or use a conical shape or a sphere.

FIG. 6(c) is an enlarged view of a part of the disk 481b viewed from above. The water W dropped onto the upper surface of the rotating disk 481b spreads in a film shape on the disk 481b due to centrifugal force, and is radiated from the disk 481b. At this time, the water W splits in a film shape from the vicinity of the edge of the disk 481b, or splits after becoming a filament, and then becomes fine particles p (water mist). According to the rotation speed of the disk 481b, that is, the rotation speed of the motor 481a, the particle size of the water mist (the diameter of the particles p) can be controlled. The higher the rotation speed, the smaller the particle size of the water mist. For example, a low-speed rotation with a rotation speed of about 1000 (rpm: revolutions per minute), a medium-speed rotation with a rotation speed of about 10,000 rpm, or a high-speed rotation with a rotation speed of about 20,000 rpm are suitably used to obtain a desired particle size. In addition, the particle size of the water mist can also be controlled by adjusting the flow rate of water W supplied from the water supply port 481c to the spray device 481.

In addition, in the specification of the present application, the particle size refers to the particle size of the fine particles p existing in the air before landing on the toilet device 10, for example, Sauter average particle size (total volume/total surface area) . The measurement method of "particle size" in the specification of the present application will be described later with reference to FIG. 21. In addition, the water mist refers to a range in which the particle diameter is 10 micrometers (μm) or more and 300 μm or less. If the particle size of the water mist is less than 10 μm, it may take a long time to wet the target parts such as the bowl 801, the bowl edge 805, and the toilet seat 200. In addition, when the sterilized water containing chlorite is used, if the particle size of the water mist is less than 10 μm, the concentration of chlorite in the water mist is easily attenuated, and the sterilization performance is easily reduced. On the other hand, if the particle size of the water mist is larger than 300 μm, it is difficult for the water mist to spread and it is difficult to spray the water mist in a wide range. In addition, in the following description, water mist with a large particle diameter refers to a water mist with a particle diameter of 100 μm or more and 300 μm or less, preferably within a range of 150 μm or more and 300 μm or less, and a water mist of a medium particle size means a particle size Water mist in the range of 50 μm or more and 200 μm or less, preferably in the range of 60 μm or more and 150 μm or less, and the water mist of small particle size refers to the range of particle size in the range of 10 μm or more and 100 μm or less, preferably in the range of 10 μm or more and 60 μm or less Water mist.

7(a) and 7(b) are plan views illustrating the disk of the spray device of the embodiment. 7(a) and 7(b) show the rotating disk 481b viewed from above. In the example of FIG. 7(a), the number of water supply ports 481c for supplying water W to the tray 481b is one. In this case, in a region close to the water supply port 481c, before the water film of the supplied water W becomes thin on the tray 481b, the water W is radiated from the tray 481b. Therefore, as shown in FIG. 7( a ), the particle size of the water mist varies around the spray device 481. That is, the region R1 where the particle diameter of the water mist is relatively large, the region R2 where the particle diameter of the water mist is intermediate, and the region R3 where the particle diameter of the water mist is relatively small. In addition, the flow rate (the amount of water mist sprayed per unit time) also varies according to the particle size of the water mist. That is, the flow rate in the region R1 is high, the flow rate in the region R2 is intermediate, and the flow rate in the region R3 is small.

Therefore, for example, the particle size, flow rate, direction, etc. of the water mist sprayed from the spray device 481 into the toilet 800 can be adjusted according to the position of the water supply port 481c and the rotation direction of the disk 481b (clockwise or counterclockwise). With this, it is also possible to control the range of the water mist sprayed from the spray device 481 and the amount of water mist sprayed in each range. In addition, a cover or the like for controlling the direction of spraying water mist may be appropriately provided around the disk 481b.

In addition, the number of water supply ports 481c is not limited to one, and a plurality of water supply ports 481c may be provided. For example, in (b) of FIG. 7, four water supply ports 481c are provided. The water supply port 481c is arranged every 90° when viewed from the center of the disk 481b. By arranging the plurality of water supply ports 481c at substantially equal intervals along the outer periphery of the disk in this manner, it is possible to suppress variations in the particle size and flow rate of the water mist around the spray device 481 and to perform uniform spraying.

The spray device 481 is disposed below the toilet seat 200 (see FIG. 2) in a state where the toilet seat device 100 is provided above the toilet 800, and sprays water mist into the toilet 800. Here, the state in which the spray device 481 is disposed below the toilet seat 200 means that at least a part of the spray device 481 (in this example, the tray 481b) is below the toilet seat 200. As a result, water mist of tap water or sterilized water is sprayed into the toilet 800 from a position below the toilet seat 200.

In addition, in the embodiment, the spray device is not limited to the devices described in FIGS. 6 and 7. For example, as a spray device, an ultrasonic atomizing device may also be used. The ultrasonic atomizing device irradiates the liquid with ultrasonic waves to form the liquid into a water mist. In addition, for example, as a spray device, a two-fluid nozzle may be used. The two-fluid nozzle simultaneously ejects gas and liquid, thereby forming the liquid into a mist of water. However, when the device described in FIGS. 6 and 7 is used, there is an advantage that it is easy to control the spray range by the air blowing device 513. In addition, the risk of clogging is also low, and no auxiliary equipment such as a compressor is required.

An example of the operation of the toilet seat device 100 in the post-toilet spray mode and the manual spray mode will be described with reference to FIGS. 8 to 10.

8 is a schematic diagram illustrating operations in the toilet spray mode and the manual spray mode of the toilet seat device of the embodiment. In the toilet spray mode and the manual spray mode, the control device 405 operates the air blowing device 513. As a result, the air blowing device 513 blows air toward the inside of the toilet 800 to generate the first upward airflow U1 in the toilet 800. In addition, the control device 405 controls the spray device 481 so that the first water mist M1 of the sterilized water and the second water mist M2 of the sterilized water are simultaneously generated in the state where the first upward airflow U1 is generated. The first water mist M1 is a water mist with a small particle diameter. The particle diameter of the first water mist M1 (the diameter of the microparticles p1 of the sterilized water) is a particle diameter that can rise to the toilet seat 200 side by the first upward airflow U1. The second water mist M2 is a water mist of medium particle size. The particle diameter of the second water mist M2 (the diameter of the fine particles p2 of the sterilized water) is larger than the particle diameter of the first water mist M1. The second water mist M2 does not rise toward the toilet seat 200 side due to the first upward airflow U1. In addition, the range in which the second water mist M2 does not rise due to the first ascending airflow U1 includes not only the case where all the second water mist M2 does not rise, but also a case where a slight amount of the second water mist M2 rises. The second water mist M2 rising by the first ascending airflow U1 is preferably as small as possible, for example, preferably zero.

That is, the first water mist M1 ejected from a portion below the toilet seat 200 rides on the first updraft U1 and rises toward the toilet seat 200 side, thereby catching water on the upper surfaces of the toilet seat 200 and the bowl edge 805 806. On the other hand, since the second water mist M2 sprayed from a portion below the toilet seat 200 has a larger particle size, it does not rise toward the toilet seat 200 side due to the first upward airflow U1, but instead catches water on the bowl 801. The inner wall surface 807 of the rim portion 805. Thereby, with the single spray device 481, the mist of the sterilized water can reach not only the bowl 801 of the toilet 800, but also the upper surface 806 of the bowl edge 805 and the toilet seat 200. Therefore, not only the bowl portion 801 of the toilet 800, but also the large area of the rim portion 805, the toilet seat portion 200, etc. can be suppressed bacteria and dirt. In addition, by using a single spray device 481, the toilet seat device 100 can be miniaturized.

Moreover, by simultaneously generating the first water mist M1 of a small particle size that can be raised by the first upward airflow U1 and the second water mist M2 of a particle size that is not raised by the first upward airflow U1, it can be arbitrarily controlled The amount of sterilized water at the bowl 801, the amount of sterilized water at the upper surface 806 of the rim 805, and the amount of sterilized water at the toilet seat 200.

In addition, the control device 405 controls the spray device 481 so that the total amount (g) of the first water mist M1 is smaller than the total amount (g) of the second water mist M2 in the post-compostion spray mode and the manual spray mode. As a result, the amount of sterilized water hitting the upper surface 806 of the toilet seat 200 and the bowl edge 805 is relatively small, and the amount of sterilized water hitting the inner wall surface 807 of the bowl 801 and the bowl edge 805 is relatively small many. By applying a large amount of water mist of the sterilized water to the basin portion 801 and the inner wall surface 807 which have a large dirt load and a high degree of tolerance to wetting, the generation of bacteria and dirt can be suppressed. The upper surface 806 of the toilet seat 200 and the rim portion 805 of the toilet seat 200 and the basin edge 805 with a small dirt load and low tolerance to wetting can reduce the amount of sterilized water, which can not only suppress bacteria and dirt, but also reduce The upper surface 806 of the toilet seat 200 and the bowl edge 805 is dried within a period of time. This can prevent the sterilized water from coming into contact with the user's skin or dripping outside the toilet.

In addition, the total amount of water mist refers to the total amount of water mist sprayed by the spray device 481 in a single spray mode (one-time post-spray mode or one manual spray mode). In the one-time spray mode, the spray device 481 may continuously spray water mist, or may spray water mist intermittently. In addition, the total amount of the first water mist M1 and the total amount of the second water mist M2 can be controlled, for example, by adjusting the rotation speed of the disk 481b, the flow rate of the sterilized water supplied to the spray device 481, and the like.

In addition, the spray device 481 sprays the sterilized water so that the first water mist M1 is formed above the second water mist M2. More specifically, the spray device 481 sprays the first water mist M1 diagonally upward with respect to the horizontal plane. In addition, the spray device 481 sprays the second water mist M2 parallel to the horizontal plane or diagonally downward. However, the direction of the first water mist M1 and the direction of the second water mist M2 may be divided up and down according to the particle size after spraying.

With this, it is possible to suppress the contact of the second water mist M2 when the first water mist M1 having a small particle diameter is raised by the first upward airflow U1. Therefore, it is possible to suppress that the particle size of the first water mist M1 becomes larger due to contact with the second water mist M2, and the first water mist M1 falls into the toilet 800.

In addition, the spray device 481 sprays each of the first water mist M1 and the second water mist M2 in a radial shape when viewed from above. Radial refers to a state where the range in which water mist exists increases as it goes away from the spray device 481. For example, when viewed from above, water mist is sprayed in all directions away from the center of the disk 481b.

Since the first water mist M1 is radial, the first water mist M1 can catch water on a large area such as the upper surface 806 of the toilet seat 200 and the bowl edge 805 by riding the entire first upward airflow U1. In addition, since the second water mist M2 is radial, even if the second water mist M2 has a particle size that is large enough to be unable to ride the airflow, the second water mist M2 can land on the basin portion 801 and the basin edge portion 805 The inner wall surface 807 and other large areas within the toilet 800.

In addition, the formation position and expansion method of the water mist (the first water mist M1 and the second water mist M2) can be performed according to the rotation speed, arrangement, shape of the disk 481b, the position of the water supply port 481c for supplying water to the disk 481b, etc. Adjustment.

9(a) and 9(b) are cross-sectional views illustrating operations in the toilet spray mode and the manual spray mode of the toilet seat device of the embodiment. FIG. 9(b) is an enlarged view of the region R4 shown in FIG. 9(a). The dotted arrow indicates the airflow formed by the air blowing device 513. As shown in FIG. 9( a ), in the post-stool spray mode and the manual spray mode, the air blowing device 513 blows air forward and downward. At least a part of the air sent from the blower 513 collides with the inside of the toilet 800 (inside the bowl portion 801 or the inner wall surface 807 of the bowl edge portion 805), and travels upward. As a result, an upward airflow U1 that rises from above the toilet seat 200 below the toilet seat 200 to above the toilet seat 200 is formed.

The solid arrow indicates the flow of water mist sprayed from the spray device 481. The thickness of the solid arrow corresponds to the amount of sterilized water. The thicker the arrow, the more sterile water. In the toilet spray mode and the manual spray mode, a part of the water mist is radiated from the spray device 481 toward the inner wall surface 807 of the bowl edge. In addition, the water mist having a relatively large particle diameter hits the basin 801. The water mist having a relatively small particle diameter is attracted to the upper surface 806 of the bowl edge portion, the toilet seat 200, the toilet lid 300, etc. due to the upward air current. With this, it is possible to sterilize the corners of the toilet device 10 including the rim portion 805, the toilet seat 200, the toilet lid 300, and the like.

In addition, in the embodiment, the nozzle 473 is arranged between the spray device 481 and the air blowing device 513 in the width direction (short-side direction) of the nozzle 473 (see FIG. 4 ). That is, the spray device 481 is arranged at a position away from the air blowing device 513 in the left-right direction. Thereby, it is possible to suppress the first water mist M1 having a small particle size from riding on the airflow (airflow before the first ascending airflow U1 is generated) from the air blowing device 513 toward the toilet 800 before riding on the first ascending airflow U1. Water within 800.

10(a) to 10(d) are plan views illustrating the operation in the toilet spray mode and the manual spray mode of the toilet seat device of the embodiment. In FIGS. 10( a) and 10 (c ), for convenience of explanation, the toilet seat 200 and the toilet lid 300 are omitted. The dotted arrow indicates the blowing direction of the blowing device 513. The solid arrow indicates the flow of water mist sprayed from the spray device 481. The thickness of the solid arrow corresponds to the amount of sterilized water. The thicker the arrow, the more sterile water. 10(b) and 10(d) show the toilet seat 200. FIG. FIGS. 10( a) and 10 (b) show how the disk 481 b of the spray device 481 rotates counterclockwise when viewed from above. In this case, the left side of the flushing device 10 has more sterilized water than the right side. For example, as shown in FIG. 10(a), on the upper surface of the rim portion of the basin, the left area RL1 has more sterilized water than the right area RR1. For example, as shown in FIG. 10(b), in the toilet seat 200, the left side area RL2 has more sterilized water than the right side area RR2.

FIGS. 10(c) and 10(d) show a state where the disk 481b of the spray device 481 rotates clockwise when viewed from above. In this case, the right side of the flushing device 10 has more sterilized water than the left side. For example, as shown in FIG. 10(c), on the upper surface of the rim portion of the pot, the right area RR1 has more sterilized water than the left area RL1. For example, as shown in FIG. 10(d), in the toilet seat 200, the right side area RR2 has more sterilized water than the left side area RL2.

The control device 405 preferably controls the motor 481a of the spray device 481 to appropriately switch between the clockwise rotation and the counterclockwise rotation in the post-stool spray mode and the manual spray mode. This makes it easy to make the distribution of water mist in the left-right direction uniform.

11 is a flowchart illustrating the operation in the toilet spray mode of the toilet seat device of the embodiment. If the human body sensor 403 detects that the user has left (step S101: Yes), the control device 405 controls the toilet cover motor 512 to close the toilet cover 300, and opens the solenoid valve 431 to cause the motor 481a and the disc 481b of the spray device 481 Rotate counterclockwise (CCW) at high speed (step S102). With the opening of the solenoid valve 431, water supply to the disk 481b starts.

The control device 405 maintains the state where the disk 481b rotates at a high speed for a predetermined time (step S103: No). By this, the residual water on the tray 481b can be discharged from the tray 481b. At this time, for example, the water mist damper 482 is closed, and therefore, water mist is not sprayed into the toilet 800.

When a predetermined time has passed (step S103: Yes), the control device 405 causes the nozzle 473 to enter the bowl 801 by the nozzle motor 476. Along with this, the water mist shutter 482 is opened (step S104).

After that, the control device 405 controls the sterilization device 450 to start generation of sterilized water, and controls the air blowing device 513 to start air blowing into the toilet 800 (step S105). As a result, mist of sterilized water is sprayed into the inside of the toilet 800, the toilet seat 200, the toilet lid 300, and the like. The control device 405 maintains the state of spraying the mist of the sterilized water from the disk 481b rotating counterclockwise at a high speed for a predetermined time (t1) (step S106: No).

When a predetermined time (t1) has elapsed (step S106: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spray device 481 clockwise (CW) at high speed (step S107). The control device 405 maintains the state of spraying the mist of the sterilized water from the disk 481b rotating clockwise at high speed for a predetermined time (t1) (step S108: No).

When a predetermined time (t1) has elapsed (step S108: Yes), the control device 405 controls the air supply device 513 to stop the air supply, controls the sterilization device 450 to stop the generation of sterilized water, and makes the motor 481a and the disk 481b clockwise (CW ) Low-speed rotation (step S109).

The control device 405 supplies tap water to the disk 481b and maintains the disk 481b rotating at a low speed for a predetermined time (step S110: No). By this, self-cleaning of the disk 481b is performed. Among them, self-cleaning refers to the operation of physically cleaning the disk at a rotation speed that does not generate water mist. Self-cleaning can also use sterile water.

When a predetermined time has passed (step S110: Yes), the control device 405 closes the solenoid valve 431 (step S111). The control device 405 will stop the water supply to the disk 481b and maintain the disk 481b rotating at a low speed for a predetermined time (step S112: No). By this, the residual water on the disk 481b can be removed.

When a predetermined time has passed (step S112: Yes), the control device 405 stops the rotation of the motor 481a and the disk 481b, and the nozzle motor 476 moves the nozzle 473 back into the housing 400. Along with this, the water mist shutter 482 is closed. In addition, the control device 405 turns on the toilet seat heater 515 (power-on state) (step S113).

The control device 405 maintains the state where the toilet seat heater 515 is turned on for a predetermined time (step S114: No). As a result, the temperature of the toilet seat 200 is increased, and the sterilized water that drips into the toilet seat 200 is evaporated, so that the toilet seat 200 can be dried. In addition, the air blower 513 and the warm air heater 514 may be driven, and the toilet seat 200 may be dried with warm air instead of the toilet seat heater 515.

When a predetermined time has passed (step S114: Yes), the control device 405 turns off the toilet seat heater 515 (non-energized state) (step S115). Through the above process, the post-spray spray mode ends.

12 is a flowchart illustrating the operation in the manual spray mode of the toilet seat device of the embodiment. When the user operates the manual operation unit 500 (step S201: Yes), the control device 405 controls the toilet cover motor 512 to close the toilet cover 300, and opens the solenoid valve 431 to cause the motor 481a and the disc 481b of the spray device 481 Rotate counterclockwise (CCW) at high speed (step S202). With the opening of the solenoid valve 431, water supply to the disk 481b starts.

The control device 405 maintains the state where the disk 481b rotates at a high speed for a predetermined time (step S203: No). By this, the residual water on the tray 481b can be discharged from the tray 481b. At this time, for example, the water mist damper 482 is closed, and therefore, water mist is not sprayed into the toilet 800.

When a predetermined time has elapsed (step S203: Yes), the control device 405 causes the nozzle 473 to enter the bowl 801 via the nozzle motor 476. Along with this, the water mist shutter 482 is opened (step S204).

Thereafter, the control device 405 controls the sterilization device 450 to start generation of sterilized water, and controls the air blowing device 513 to start air blowing into the toilet 800 (step S205). As a result, mist of sterilized water is sprayed into the inside of the toilet 800, the toilet seat 200, the toilet lid 300, and the like. The control device 405 maintains the state of spraying the mist of the sterilized water from the disk 481b rotating counterclockwise at high speed for a predetermined time (t2) (step S206: No).

When a predetermined time (t2) has elapsed (step S206: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spray device 481 clockwise (CW) at high speed (step S207). The control device 405 maintains the state of spraying the mist of the sterilized water from the disk 481b rotating clockwise at high speed for a predetermined time (t2) (step S208: No).

When a predetermined time (t2) has elapsed (step S208: Yes), the control device 405 controls the air supply device 513 to stop the air supply, controls the sterilization device 450 to stop the generation of sterilized water, and rotates the motor 481a and the disk 481b clockwise (CW) Low speed rotation (step S209).

The control device 405 maintains the state where the tap water is supplied to the disk 481b and the disk 481b is rotated at a low speed for a predetermined time (step S210: No). By this, self-cleaning of the disk 481b is performed.

When a predetermined time has passed (step S210: Yes), the control device 405 closes the solenoid valve 431 (step S211). The control device 405 will stop the water supply to the disk 481b and maintain the disk 481b rotating at a low speed for a predetermined time (step S212: No). By this, the residual water on the disk 481b can be removed.

When a predetermined time has elapsed (step S212: Yes), the control device 405 stops the rotation of the motor 481a and the disk 481b, and the nozzle motor 476 moves the nozzle 473 back into the housing 400. Along with this, the water mist shutter 482 is closed (step S213). Through the above process, the manual spray mode is ended. In addition, after the user in the manual spray mode, the toilet seat 200 can be sterilized by appropriately wiping off the sterilized water that has hit the toilet seat 200 with toilet paper or the like.

The control device 405 controls the spraying device so that the time for spraying the sterilized water in the manual spray mode is longer than the time for spraying the sterilized water in the post-commode spray mode. For example, the predetermined time (t2) explained with reference to FIG. 12 is longer than the predetermined time (t1) explained with reference to FIG. 11. This makes it possible to increase the amount of sterilized water that enters the toilet seat 200 in the manual spray mode compared to the amount of sterilized water that enters the toilet seat 200 in the post-stool spray mode. By this, in the manual spray mode, the sterilization water is sufficiently saturated with toilet paper, etc., so that the sterilization performance can be improved. In addition, the toilet seat 200 made of resin can be prevented from being damaged during wiping.

For example, there may be a method of changing the water injection amount of the sterilized water without changing the time when the sterilized water is sprayed, but by changing the particle size of the mist of the sterilized water. For example, by increasing the particle size, it is possible to increase the water intake of the sterilized water. However, if the particle size is increased, it may be difficult for the sterilized water to ride up the airflow. In response to this, by changing the time at which the sterilized water is sprayed, the amount of sterilized water that enters the toilet seat 200 and the like can be increased without changing the particle size. Therefore, the mist of the sterilized water can be easily carried on the ascending airflow, and the sterilized water can be spread over a large area such as the toilet seat 200.

In addition, the control device 405 causes the drying device that dries the toilet seat 200 to operate at the first drying force during or after execution of the toilet flushing mode. For example, in FIG. 11, the control device 405 operates the toilet seat heater 515 at the first heating amount (first electric power (watt)) in steps S113 and S114. On the other hand, during or after the execution of the manual spray mode, the control device 405 does not operate the drying device or operates it with the second drying force smaller than the first drying force. For example, in FIG. 12, the control device 405 does not operate the toilet seat heater 515. Alternatively, the control device 405 may operate the toilet seat heater 515 with a second heating amount (second electric power (watt)) smaller than the first heating amount. For example, with the toilet seat heater 515, the temperature of the seat surface during or after the toilet spray mode is performed is higher than the temperature of the seat surface during or after the manual spray mode.

In this way, during or after the toilet spray mode is executed, the drying device dries the toilet seat 200 with a relatively large first drying force (for example, the first electric power), so that the removal of water on the toilet seat 200 can be shortened Drying time of bacteria water. On the other hand, during or after execution of the manual spray mode, the drying device does not operate, or the toilet seat 200 is dried with a relatively small second drying force (for example, second power), so that water can be added to the toilet seat Drying time of the sterilized water of the toilet seat 200. With this, it is possible to prevent the toilet seat 200 from drying out before wiping off the sterilized water on the toilet seat 200 with toilet paper.

An example of the operation of the toilet seat device 100 in the pre-toilet spray mode will be described with reference to FIGS. 13 to 15. Fig. 13 is a schematic diagram illustrating the operation in the pre-commode spray mode of the toilet seat device of the embodiment. In the pre-condensation spray mode, the control device 405 operates the spray device 481 to generate water mist M3 (sterilized water mist or tap water mist). In addition, the control device 405 controls the air blowing device 513 so that the first ascending airflow U1 is not generated while the spray device 481 sprays the water mist M3, and the water mist M3 is not raised toward the toilet seat 200 side. Among them, the first ascending airflow U1 is an airflow produced by the air blowing device 513 as described above, and is an airflow capable of raising the mist of the sterilized water toward the toilet seat 200 side in the post-toilet spray mode and the manual spray mode.

In the pre-toilet spray mode, the water mist sprayed from a portion below the toilet seat 200 does not rise toward the toilet seat 200 side, but hits the inner wall surface 807 of the bowl 801 and the bowl edge 805 of the toilet 800 . A water film is formed on the bowl portion 801 and the inner wall surface 807, making it difficult to attach dirt. In addition, since the water mist does not rise toward the toilet seat 200 side, it is possible to suppress the upper surface 806 of the toilet seat 200 and the bowl edge 805 from being wetted in the pre-stool spray mode. Thereby, in the case where the user takes a seat immediately after the pre-spray spray mode or turns the toilet seat 200 by hand, the user's hands and buttocks can be prevented from being wet. On the other hand, in the toilet spray mode and the manual spray mode, the control device 405 operates the air blowing device 513, and the mist of the sterilized water is raised toward the toilet seat 200 side by the first upward air flow U1.

That is, the control device 405 can be switched between the case where the water mist sprayed from a portion below the toilet seat 200 rides on the updraft and hits the toilet seat 200, and the case where the water mist does not ride on the updraft. Thereby, it is possible to use a single spray device 481 to spray the water of the sterilized water into the toilet 800 and the toilet seat 200 in the post-toilet spray mode and the manual spray mode, but not to moisten the pre-toilet spray mode. The manner of the wet toilet seat 200 causes water mist to enter the toilet 800.

In addition, the range of "do not raise the water mist of the sterilized water or the water mist of the tap water to the toilet seat side" in the pre-paste spray mode includes not only the case where all the water mist does not rise, but also a small amount of water The fog rises. For example, the amount of water mist that rises toward the toilet seat side in the pre-toilet spray mode is smaller than the amount of water mist that rises toward the toilet seat part in the post-toilet spray mode or the manual spray mode.

For example, in the pre-detox spray mode, the control device 405 stops the operation of the air blowing device 513 without blowing air. With this, it is possible to more reliably prevent the water mist from rising toward the toilet seat 200 side.

In addition, in the pre-detox spray mode, the control device 405 may operate the air blowing device 513 to generate the second upward airflow U2. The flow velocity of the second upward airflow U2 is lower than the flow velocity of the first upward airflow U1, and the water mist M3 does not rise toward the toilet seat 200 side by the second upward airflow U2. The second upward airflow U2 can diffuse the water mist in the horizontal direction or downward without rising to the toilet seat 200 side. In this way, the sterilized water can be flooded in the toilet 800 in a larger area.

In addition, in the pre-condensation spray mode, the spray device 481 also sprays the water mist of the sterilized water or the water mist of the tap water radially when viewed in plan. Thereby, even in the case where the water mist is not on the updraft in the pre-stove spray mode, the water mist can be caught on a large area such as the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805.

The water mist M3 is, for example, a water mist having a medium particle diameter or a large particle diameter. The particle size of the water mist M3 (the diameter of the particles p3 of the sterilized water or tap water) may be larger than the particle diameter of the first water mist M1 and the second water mist M2 in the manual spray mode and the post-stool spray mode, for example. . With this, the water mist M3 can also be prevented from rising toward the toilet seat 200 side.

14(a) to 14(c) are a cross-sectional view and a plan view illustrating the operation in the pre-stool spray mode of the toilet seat device of the embodiment. 14(a) to 14(c) illustrate an example where the motor 481a of the spray device 481 is rotating at a medium speed. At this time, the water mist sprayed by the spray device 481 is a water mist of medium particle size. In addition, in FIGS. 14( a) to 14 (c ), solid arrows indicate the flow of water mist sprayed from the spray device 481. The thickness of the solid arrow corresponds to the amount of sterilized water. The thicker the arrow, the more sterile water. In addition, in FIGS. 14(b) and 14(c), the toilet seat 200 is omitted for convenience of explanation.

As shown in the cross-sectional view of FIG. 14( a ), the spray device 481 sprays water mist toward the upper end of the rim portion 805. When the motor 481a rotates at a medium speed, the outer region RS of the toilet 800 (the outer portion 801S in the bowl 801 and the inner wall surface 807 of the bowl edge 805) is larger than the inner region RU of the toilet 800 (the inner portion of the bowl 801) 801U) Get more sterile water or tap water.

The top view of FIG. 14(b) shows how the disk 481b of the spray device 481 rotates counterclockwise when viewed from above. In this case, the left side of the toilet 800 has more sterilized water or tap water than the right side.

The top view of FIG. 14(c) shows a state in which the disk 481b of the spray device 481 rotates clockwise when viewed from above. In this case, the right side of the toilet 800 has more sterilized water or tap water than the left side.

15(a) to 15(c) are a cross-sectional view and a plan view illustrating the operation in the pre-stool spray mode of the toilet seat device of the embodiment. 15(a) to 15(c) illustrate the state in which the motor 481a of the spray device 481 is rotating at a low speed. At this time, the water mist sprayed by the spray device 481 is a water mist with a large particle diameter. In addition, in FIGS. 15( a) to 15 (c ), solid arrows indicate the flow of water mist sprayed from the spray device 481. The thickness of the solid arrow corresponds to the amount of sterilized water. The thicker the arrow, the more sterile water. In addition, in FIGS. 15(b) and 15(c), the toilet seat 200 is omitted for convenience of explanation.

When the motor 481a rotates at a low speed, the particle size of the water mist is larger and the centrifugal force is smaller than the motor rotates at a medium speed, so the flying distance of the water mist becomes shorter. As shown in the cross-sectional view of FIG. 15( a ), when the motor 481 a rotates at a low speed, the inner region RU of the toilet 800 has more sterilized water or tap water than the outer region RS of the toilet 800.

The top view of FIG. 15(b) shows how the disk 481b of the spray device 481 rotates clockwise when viewed from above. In this case, the right side of the toilet 800 has more sterilized water or tap water than the left side.

The top view of FIG. 15(c) shows how the disk 481b of the spray device 481 rotates counterclockwise when viewed from above. In this case, the left side of the toilet 800 has more sterilized water or tap water than the right side.

The control device 405 controls the motor 481a of the spray device 481 so that the low-speed rotation and the medium-speed rotation are appropriately switched in the pre-concentration spray mode. As a result, the water mist of the sterilized water or tap water can reach the corners of the toilet 800.

In addition, the control device 405 preferably controls the motor 481a of the spray device 481 to appropriately switch between clockwise rotation and counterclockwise rotation in the pre-concentration spray mode (during low-speed rotation and medium-speed rotation). As a result, the distribution of water mist in the left-right direction tends to become uniform.

16 is a flowchart illustrating the operation in the toilet spray mode of the toilet seat device of the embodiment. If the human body sensor 403 detects the user entering the room (step S301: Yes), the control device 405 controls the toilet lid motor 512 to open the toilet lid 300, and opens the solenoid valve 431, so that the motor 481a of the spray device 481 and The disk 481b rotates counterclockwise (CCW) at a medium speed (step S302). With the opening of the solenoid valve 431, water supply to the disk 481b starts.

The control device 405 maintains the state where the disk 481b rotates at a medium speed for a predetermined time (step S303: No). By this, the residual water on the tray 481b can be discharged from the tray 481b. At this time, for example, the water mist damper 482 is closed, and therefore, water mist is not sprayed into the toilet 800.

When a predetermined time has passed (step S303: Yes), the control device 405 uses the nozzle motor 476 to cause the nozzle 473 to enter the bowl 801. Along with this, the water mist shutter 482 is opened (step S304). As a result, the spray of tap water into the toilet 800 is started. The control device 405 maintains the state of spraying the water mist of the tap water from the disc 481b rotating counterclockwise at a medium speed (step S305: No).

When a predetermined time has passed (step S305: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spray device 481 at a medium speed (CW) clockwise (step S306). The control device 405 maintains the state of spraying the water mist of the tap water from the disc 481b rotating clockwise at a medium speed for a predetermined time (step S307: No).

When a predetermined time has passed (step S307: Yes), the control device 405 rotates the motor 481a and the disc 481b of the spray device 481 clockwise (CW) at a low speed (step S308). The control device 405 maintains the state of spraying the water mist of the tap water from the disk 481b rotating clockwise at a low speed for a predetermined time (step S309: No).

When a predetermined time has passed (step S309: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spray device 481 counterclockwise (CCW) at a low speed (step S310). The control device 405 maintains the state of spraying the water mist of the tap water from the disk 481b rotating counterclockwise at a low speed for a predetermined time (step S311: No).

When a predetermined time has passed (step S311: Yes), the control device 405 closes the solenoid valve 431 (step S312). The control device 405 will stop the water supply to the disk 481b and maintain the disk 481b rotating at a low speed for a predetermined time (step S313: No). By this, the residual water on the disk 481b can be removed.

When a predetermined time has passed (step S313: Yes), the control device 405 stops the rotation of the motor 481a and the disk 481b, and the nozzle motor 476 moves the nozzle 473 back into the housing 400. Along with this, the water mist shutter 482 is closed (step S314). Through the above process, end the pre-spraying mode.

The control device 405 executes the pre-stool spray mode with the toilet lid 300 opened. That is, in the pre-deto spray mode, water mist is sprayed with the toilet cover 300 opened. Thereby, the user can immediately sit on the toilet seat 200 without waiting for the execution of the pre-pneumatic spray mode to be completed. In addition, in the pre-toilet spray mode, the spray device 481 sprays in such a manner that the water mist does not land on the toilet seat 200. Therefore, even when the user is seated on the toilet seat 200 during execution of the pre-toilet spray mode In this case, the possibility of the user being sprayed with water mist is also low.

On the other hand, the control device 405 executes the toilet spray mode and the manual spray mode with the toilet lid 300 closed. That is, in the toilet spray mode and the manual spray mode, water mist is sprayed with the toilet cover 300 closed. Thereby, the mist of the sterilized water can be prevented from scattering outside the toilet, and the mist of the sterilized water can be diffused to suppress bacteria and dirt in a large area of the toilet 800, the toilet seat 200, the toilet lid 300, and the like.

17 is a flowchart illustrating the operation of the toilet seat device of the embodiment. 18(a) and 18(b) are schematic views illustrating the operation of the toilet seat device of the embodiment. FIG. 18(b) shows the target parts P1 to P4 of the water sprayed by the water mist of the sterilized water or tap water. Fig. 18(a) shows the water injection amount (water injection amount per unit area) of each target part in each spray mode in four stages of "large", "medium", "small", and "very small".

In the pre-detox spray mode, after the sensor 402 changes from the state in which the user is not detected to the state in which the user is detected, the sterilized water or tap water is not applied to the toilet seat 200 to automatically change The water mist of the sterilized water or the water mist of the tap water is sprayed into the toilet 800.

For example, as shown in FIG. 17, if the user enters the toilet and the human body sensor 403 detects the user's entrance, a signal (detection information) indicating the user's entrance is sent to the control device 405. The control device 405 automatically executes the pre-stool spray mode based on the signal. In the pre-condensation spray mode, the control device 405 causes the spray device 481 to spray the water mist of the tap water, so that the water mist hits the target part. As shown in FIG. 18(a) and FIG. 18(b), the target parts in the pre-stool spray mode are the target part P3 (the inner wall surface 807 of the pot edge 805) and the target part P4 (pot part 801). In the pre-contrast spray mode, the upper surface 806 of the toilet seat 200 and the bowl edge 805 is not a part to be sprayed.

In this way, before the toilet seat device 100 is used, the sterilized water or tap water is flooded into the toilet 800 by the pre-commode spray mode. As a result, a water film is formed in the toilet 800 that has a large dirt load and a high degree of tolerance to wetting, thereby suppressing firm adhesion of dirt. On the other hand, on the upper surface 806 of the toilet seat 200 and the bowl edge 805 with a small dirt load, even if the water film is not formed by the pre-stool spray mode, it can be sprayed by the post-stool after the use of the toilet seat device 100 The mode allows the sterilized water to catch water to suppress the firm adhesion of dirt. For this reason, the toilet seat device 100 sprays the water mist of the sterilized water or tap water into the toilet seat 800 so as not to reach the toilet seat portion 200 in the pre-commode spray mode. In this way, the pre-stomach spray mode and the post-stomach spray mode can suppress the generation of bacteria and dirt in a large area of the toilet 800, the toilet seat 200, etc., and can prevent the sterilization sprayed by the pre-stool spray mode. Wet the user with water or tap water. For example, even when the user turns the toilet seat 200 by hand or sits on the toilet seat 200 immediately after the pre-spray spray mode is executed, it is possible to prevent the user's buttocks, hands, and water from reaching the toilet seat. Contact with fungus water or tap water. That is, the user can use the toilet seat device 100 immediately without being wet by water mist.

In addition, in the pre-stool spray mode, by not allowing water mist to land on the toilet seat 200, a water film can be formed in the toilet 800 in a short time, and the execution time of the pre-stool spray mode can be shortened. A user who enters the toilet can use the toilet seat device 100 without waiting for the end of the pre-spray spray mode.

In addition, the range of "sterilized water or tap water does not reach the toilet seat" in the spray mode before toilet includes not only the case where all the water mist is on the toilet seat 200, but also a small amount of water When the toilet seat 200 is fogged with water. For example, the amount of tap water or sterilized water that hits the toilet seat 200 in the pre-stool spray mode is smaller than the amount of sterilized water that hits the toilet seat 200 in the post-stool spray mode or the manual spray mode. However, in the pre-commode spray mode, the amount of the sterilized water or tap water that hits the toilet seat 200 is preferably as small as possible, for example, preferably zero.

In the toilet spray mode, after the sensor 402 changes from the state where the user is detected to the state where the user is not detected, the water mist of the sterilized water is automatically sprayed into the toilet 800 and the toilet seat 200.

For example, as shown in FIG. 17, if the user exits from the toilet and the human sensor 403 detects that the user is away, a signal (detection information) indicating that the user is away is sent to the control device 405. The control device 405 automatically executes the toilet spray mode based on the signal. In the toilet spray mode, the control device 405 causes the sterilization device 450 to generate sterilized water, and the spray device 481 sprays the water mist of the sterilized water, so that the water mist hits the target site. As shown in FIG. 18(a) and FIG. 18(b), the target parts in the post-stool spray mode are the target part P1 (surface 203 of the toilet seat 200), the target part P2 (back surface 204 of the toilet seat 200, and the basin The upper surface 806 of the edge 805), the target part P3 and the target part P4.

In this way, by performing the toilet spray mode, after the user uses the toilet seat device 100, the sterilized water can be automatically poured into the toilet 800 and the toilet seat 200. With this, not only the toilet 800 but also the toilet seat 200 and the like can be automatically suppressed from generating bacteria and dirt.

In addition, since the post-commode spray mode is executed after the user uses the toilet seat device 100, it is easier to ensure a longer non-use time than before use. Therefore, even if the upper surfaces 806 of the toilet seat 200 and the rim portion 805 are wetted by the post-stool spray mode, it is easy to dry the upper surfaces 806 of the toilet seat 200 and the rim portion 805 before the next use.

In the manual spray mode, after the user operates the manual operation unit 500, the mist of the sterilized water is sprayed into the toilet 800 and the toilet seat 200.

For example, as shown in FIG. 17, if the user operates the manual operation unit 500 during the toilet entry process (for example, after the pre-contrast spray mode is executed), a signal (operation information) corresponding to the operation is sent to the control device 405. The control device 405 executes the manual spray mode based on this signal. The manual spray mode is executed at the timing such as before use/after use/cleaning of the toilet seat device 100. In the manual spray mode, the control device 405 causes the sterilization device 450 to generate sterilized water, and the spray device 481 sprays the water mist of the sterilized water, so that the water mist hits the target part. As shown in FIGS. 18(a) and 18(b), the target parts in the manual spray mode are target part P1, target part P2, target part P3, and target part P4.

In this way, with the manual spray mode, the sterilized water is poured into the toilet 800 and the toilet seat 200 to further suppress the generation of bacteria and dirt. For example, it can be sterilized by wiping off the sterilized water that has been applied with toilet paper or the like to firmly adhere to the dirt that is difficult to suppress by the post-stool spray mode. The user can simply wipe and sterilize without using special sterilization paper. In addition, for example, a user who cares about the dirt of the toilet seat 200 before using the toilet seat device 100 can sterilize the toilet seat 200 by the manual spray mode. Since the sterilization is performed based on the user's own operation, the user's sense of security and satisfaction can be improved.

As shown in FIG. 17, for the control device 405, when the manual spray mode is executed in the state where the sensor detects the user, even if the sensor changes from the state where the user is detected to the state where the user is not detected In the case of the state, the toilet spray mode is also executed. By this, even if the user performs the manual spray mode before using the toilet seat device 100 (defecation, urination), the post-commode spray mode is executed, whereby the generation of bacteria and dirt can be more reliably suppressed.

However, when the user has left the toilet immediately after the manual spray mode is ended, there is a possibility that the sterilized water that has water on the upper surface 806 of the toilet seat 200 and the bowl edge 805 is not wiped off. For example, as shown in FIG. 17, when the manual spray mode is executed after the toilet seat device 100 is used, and the sensor is in a state where the user is not detected within the first predetermined time T1 from the end of the manual spray mode There is a possibility that the sterilized water remains on the upper surface 806 of the toilet seat 200 and the bowl edge 805.

Therefore, the control device 405 may not be executed when the sensor changes from the state where the user is detected to the state where the user is not detected within the first predetermined time T1 from the end of the manual spray mode Spray mode after stool. Alternatively, the control device 405 may set the amount of the sterilized water sprayed by the spray device 481 in the post-continuous spray mode to be less than that after the first predetermined time T1 has elapsed since the end of the manual spray mode. When the state of becomes the state in which the above-mentioned user is not detected, it becomes less. This can prevent the upper surface 806 of the toilet seat 200 and the bowl edge 805 from being excessively wetted by the post-stool spray mode, which causes the sterilized water to drip out of the toilet. The first predetermined time T1 is, for example, about 10 to 30 seconds. However, the first predetermined time T1 is not limited to this, and can be appropriately set.

In addition, when the next user enters the toilet immediately after the toilet spray mode ends, there is a possibility that the upper surface 806 of the toilet seat 200 and the bowl edge 805 is being wetted by the sterilized water. For example, when the next user enters the toilet and operates the manual operation unit 500 within the second predetermined time T2 from the end of the post-spray spray mode, there is a possibility that the toilet seat 200 and the rim of the toilet The upper surface 806 of the 805 still has sterilized water remaining.

For this reason, when the manual operation unit 500 is operated within the second predetermined time T2 from the end of the post-spray spray mode, the control device 405 may not execute the manual spray mode. Alternatively, the control device 405 may adjust the amount of the sterilized water sprayed by the spray device 481 in the manual spray mode as compared to the case where the manual operation unit 500 is operated after the second predetermined time T2 has elapsed since the end of the post-spray spray mode. Words become less. Thereby, it is possible to prevent the upper surface 806 of the toilet seat 200 and the bowl edge 805 from being excessively wetted by the manual spray mode, and causing the sterilized water to drip out of the toilet. The second predetermined time T2 is, for example, about 10 seconds to 30 seconds. However, the second predetermined time T2 is not limited to this, and can be appropriately set.

In addition, the control device 405 controls the spray device so that the amount of water per unit area (average amount of water) per unit area of the sterilized water that is applied to the toilet seat 200 in the manual spray mode is lower than the amount of water applied to the toilet seat after the toilet spray mode The sterilized water of the unit 200 has a large amount of water (average amount of water) per unit area of sterilized water. For example, as shown in FIG. 18( a ), in the manual spray mode, the amount of sterilized water per unit area that hits the target site P1 and the target site P2 is “small”. In addition, in the post-stool spray mode, the amount of sterilized water per unit area hitting the target site P1 is "very small", and the amount of sterilized water per unit area hitting the target site P2 is "small" .

In this way, since the amount of sterilized water that hits the toilet seat 200 in the post-toilet spray mode is relatively small, the toilet seat 200 can be dried in a short time after spraying after the toilet. With this, even when the user uses the toilet seat device 100 after spraying the stool, it is possible to prevent the sterile water from coming into contact with the user's hands and buttocks. In addition, in the manual spray mode, the amount of the sterilized water that hits the toilet seat 200 is relatively large, so the sterilized water can be sufficiently saturated with toilet paper or the like. Thereby, the sterilization performance by wiping can be improved, and the toilet seat 200 made of resin can be suppressed from being damaged during wiping. Therefore, it is possible to have both the drying performance of the post-continence spray mode and the wiping performance of the manual spray mode.

In addition, as shown in FIG. 18( a ), in the manual spray mode and the post-stool spray mode, the amount of the sterilized water per unit area of the target area P3 and the target area P4 is “large”. On the other hand, in the pre-stool spray mode, the amount of sterilized water per unit area that hits the target site P3 and the target site P4 is “medium”. After the toilet seat device 100 is used, by flooding the toilet 800 with a large amount of sterilized water, the generation of bacteria and dirt can be further suppressed.

In addition, for example, the control device 405 controls the spray device so that the particle size of the water mist of the sterilized water sprayed in the post-toilet spray mode is smaller than that of the tap water (or sterilized water) sprayed in the pre-too spray mode. The particle size of the water mist is small. In addition, the control device 405 controls the spray device so that the particle size of the water mist of the sterilized water sprayed in the manual spray mode is smaller than the water mist of the tap water (or sterilized water) sprayed in the pre-stool spray mode. The particle size is small.

In this way, by reducing the particle size of the water mist in the post-stool spray mode and the manual spray mode, the water mist of the sterilized water is likely to spread to a wide range. Thereby, not only the basin 801 but also the rim portion 805, the toilet seat 200, etc. can be suppressed in a large range of bacteria and dirt. In the pre-commode spray mode, by increasing the particle size of the water mist, a water film can be formed on the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805 in a short time. With this, it is possible to end the pre-stool spray mode before the user sits on the toilet seat.

In an embodiment, the control device 405 controls the spray device 481 in a single spray mode (for example, a one-time toilet spray mode) so that the sterilized water has an amount of water per unit area at the toilet seat 200, and The amount of water per unit area of the sterilized water at the upper surface 806 of the rim portion 805 is smaller than the amount of water per unit area of the sterilized water at the rim portion 801, respectively The amount of water per unit area at the inner wall surface 807 of 805 is small.

That is, according to the embodiment, in the one-shot spray mode, the control device 405 makes the amount of the sterilized water hitting the inner wall surface 807 of the bowl portion 801 and the bowl edge portion 805 relatively large. By applying a large amount of water mist of the sterilized water to the inner wall surface 807 of the basin portion 801 and the basin edge portion 805 that have a large dirt load and a high degree of tolerance to wetting, the generation of bacteria and dirt can be suppressed.

In addition, according to the embodiment, in the one-time spray mode, the control device 405 makes the amount of sterilized water hitting the upper surface 806 of the toilet seat 200 and the flange portion 805 relatively small. Since the upper surface 806 of the toilet seat 200 and the flange 805 has a relatively small dirt load, it is possible to suppress bacteria and dirt by flooding a relatively small amount of sterilized water.

In addition, on the upper surface 806 of the toilet seat 200 and the toilet rim 805 with low tolerance to wetting, the toilet seat 200 and the toilet rim can be made in a short time by reducing the amount of sterilized water The upper surface 806 of 805 dries. This can prevent the sterilized water from coming into contact with the user's skin or dripping outside the toilet.

In this way, according to the embodiment, it is possible to suppress bacteria and dirt not only in the toilet bowl 801 but also in the rim portion 805 and the toilet seat 200, etc., and it can prevent the sterilized water from coming into contact with the user's skin. Discomfort and sterilized water dripping out of the toilet.

For example, the control device 405 controls the spray device 481 so that the water volume at the toilet seat 200 (sterilized water volume per unit area at the toilet seat) becomes water at the toilet seat in the single spray mode The sterilized water of the unit 200 does not drip but stays in the amount of water. In addition, the control device 405 controls the spray device so that the amount of water permeated at the upper surface 806 of the rim portion 805 (sterilized water per unit area of water at the upper surface of the rim portion) in the single spray mode The amount of sterilized water that becomes water on the upper surface 806 of the basin edge 805 does not drip but stays.

In this way, since the sterilized water does not drip but stays on the upper surface 806 of the toilet seat 200 and the rim 805 with a small dirt load, the time for the oxidative decomposition and bleaching of the sterilized water can be ensured to be long , Can inhibit the production of bacteria and dirt. In addition, by making the amount of water on the upper surface 806 of the toilet seat 200 and the bowl edge 805 the amount of water that can retain the sterilized water, the risk of the sterilized water dripping out of the toilet can be reduced.

In addition, the control device 405 controls the spray device 481 so that the flooding amount at the pot 801 (sterilization water per unit area at the pot) in the one-time spray mode becomes the flooding at the pot 801 The amount of water dripping from the bacteria. In addition, the control device 405 controls the spray device 481 so that the amount of water per unit area on the inner wall surface 807 of the rim portion 805 (sterilized water per unit area of water on the inner wall surface of the rim portion in the single spray mode) ) Becomes the amount of water that reaches the inner wall surface 807 of the rim portion 805 of the sterilized water drops.

In this way, by dropping the sterilizing water on the inner wall surface 807 of the basin portion 801 and the basin edge portion 805 where the dirt load is large, not only the oxidative decomposition and bleaching effects but also the sterilizing water can be used to flush the dirt The role of walking. With this, it is possible to suppress the generation of bacteria and dirt more effectively than in the case where the sterilized water is retained.

In addition, "drip" means that water (for example, sterilized water) attached to the surface of an object flows down. The scope of "drip" includes the case where water droplets and water film flow due to their own weight, and the case where they flow due to vibration due to the action of the toilet flushing device.

For example, the control device 405 controls the spray device so that the amount of water at the toilet seat 200 becomes the removal of the water on the toilet seat 200 when the toilet seat 200 is rotated by the toilet seat motor 511 (rotating device) Bacterial water does not drip but the amount of water retained.

Thereby, even when the toilet seat 200 is rotated, the sterilization water droplets can be prevented, so the oxidative decomposition and bleaching action of the sterilization water can be ensured for a longer period of time, and the generation of bacteria and dirt can be further suppressed . In addition, by setting the amount of water at the toilet seat 200 to be the amount of water that can retain the sterilized water, the risk of the sterilized water dripping to an unintended part can be reduced.

The control of the above-mentioned water injection amount can be performed by controlling the particle diameter of the water mist sprayed from the spray device 481. For example, the control device 405 controls the spray device 481 so that the particle size of the water mist of the sterilized water sprayed to the toilet seat 200 and the water mist of the sterilized water sprayed to the upper surface 806 of the bowl edge 805 The particle size is smaller than the particle size of the mist of the sterilized water sprayed to the bowl portion 801, and is smaller than the particle size of the water mist of the sterilized water sprayed to the inner wall surface 807 of the bowl edge portion 805, respectively. Among them, the particle size of the water mist of the sterilized water sprayed to each part is, for example, the particle size of the water mist directed to the water at each part.

Since the diameter of the mist of the sterilized water on the upper surface 806 of the toilet seat 200 and the bowl edge 805 is small, the sterilized water on the upper surface of the toilet seat and the bowl edge can be made difficult Shed. In addition, since the particle size of the mist of the sterilized water that hits the inner wall surface 807 of the basin portion 801 and the basin edge portion 805 is large, it is possible to remove the water that hits the inner wall surface 807 of the basin portion 801 and the basin edge portion 805 The fungus water flows down easily, which can improve the effect of washing away dirt.

The method of measuring the amount of water (average amount of water) will be described with reference to FIGS. 19(a) to 19(e). 19(a) to 19(e) are plan views illustrating the toilet device of the embodiment. 19(a) and 19(b) show the front surface 203 of the toilet seat 200 and the back surface 204 of the toilet seat 200, respectively. The surface 203 is a seating surface for a user to sit on, and faces upward when the toilet seat 200 is closed. The rear surface 204 is a surface opposite to the surface 203, and faces downward when the toilet seat 200 is closed.

As shown in FIG. 19(b), the back surface 204 has a front end region 204F located on the front side, a side region 204R located on the right side, and a side region 204L located on the left side when the toilet seat 200 is closed. The area of each area is set to 20 cm 2 (cm ² ). The amount of water per unit area of the front end region 204F (g/cm ² ), the amount of water per unit area of the side region 204R (g/cm ² ), and the amount of water per unit area of the side region 204L (g /cm ² ) is the average value of the amount of water per unit area of the back surface 204 (average amount of water (g/cm ² )).

The amount of water per unit area of the toilet seat 200 (average amount of water (g/cm ² )) is the average of the amount of water per unit area of the surface 203 and the amount of water per unit area of the back 204.

As shown in FIG. 19(c), the upper surface 806 of the rim portion 805 has a front end region 806F located on the front side, a side region 806R located on the right side, and a side region 806L located on the left side. The area of each area is set to 20 cm 2 (cm ² ). The amount of water per unit area of the upper surface 806 of the rim portion 805 (average amount of water (g/cm ² )) is the amount of water per unit area of the front end region 806F (g/cm ² ), and the side area 806R the average amount of water per unit area of the amount of water per unit area (g / cm ^2), and side region 806L in (g / cm ²⁾ of the.

As shown in FIG. 19(d), the inner wall surface 807 of the rim portion 805 has a front end region 807F located on the front side, a side region 807R located on the right side, and a side region 807L located on the left side. The area of each area is set to 20 cm 2 (cm ² ). The amount of water per unit area of the inner wall surface 807 of the rim portion 805 (average amount of water (g/cm ² )) is the amount of water per unit area of the front end region 807F (g/cm ² ), and the side area 807R the average amount of water per unit area of the amount of water per unit area (g / cm ^2), and side region 807L in (g / cm ²⁾ of the.

As shown in FIG. 19(e), the bowl portion 801 (the portion of the inner surface of the bowl portion 801 where no water is stored) has a front end area 801F on the front side, a side area 801R on the right side, and a left side Square side area 801L. The area of each area is set to 20 cm 2 (cm ² ). The amount of water per unit area of the basin 801 (average amount of water (g/cm ² )) is the amount of water per unit area of the front end area 801F (g/cm ² ), and the amount of water per unit area of the side area 801R average water amount of water per unit area (g / cm ^2), and side region 801L in (g / cm ²⁾ of the.

19(a) to 19(e) for each area (203F, 203L, 203R, 204F, 204L, 204R, 806F, 806L, 806R, 807F, 807L, 807R, 801F, 801L, and 801R) The method of measuring the amount of water per unit area is as follows. First, after spraying water mist, wipe a certain area with paper to make the paper absorb the water mist in the area. Next, the difference between the weight of the paper before the water absorption and the weight of the paper after the water absorption is taken as the amount of water mist (watering amount) on the area. The amount of water permeated per unit area of the area is calculated by dividing the amount of water permeated by the area of the area (wipe area).

FIG. 20 is a graph illustrating the amount of water sprayed in the post-continuous spray mode. In FIG. 20, the amount of water per unit area of each area shown in FIGS. 19(a) to 19(e) is shown in four stages of "large", "medium", "small", and "very small". Size relationship. For example, the amount of water per unit area of the front end region and the side region of the upper surface 806 of the rim portion 805 is “medium”. On the other hand, the amount of water per unit area of the front end region and the side region of the surface 203 of the toilet seat 200 is “very small”.

That is, the control device 405 controls the spray device 481 so that the amount of water per unit area of the sterilized water at the upper surface 806 of the rim portion 805 is smaller than the amount of water sterilized at the surface 203 of the toilet seat 200 The amount of water per unit area is large. By making the amount of sterilized water on the upper surface 806 of the bowl edge 805 with a low possibility of direct contact by the user more than the surface 203 of the toilet seat 200 directly touched by the user, the bowl edge can be suppressed The generation of bacteria and dirt at the upper surface 806 of the portion 805.

In addition, when the user is seated on the toilet seat 200 to urinate, urine and sewage splashed by touching the bowl 801 and the stored water 801w are likely to adhere to the front side of the back surface 204 of the toilet seat 200. Therefore, the front side of the back surface 204 of the toilet seat 200 is a portion where the dirt load is greater than the side of the back surface 204 of the toilet seat 200. On the other hand, as shown in FIG. 20, the amount of water per unit area of the front end region of the back surface 204 of the toilet seat 200 is "large", and the amount of water per unit area of the side region of the back surface 204 of the toilet seat 200 The amount of water is "small".

That is, when the part of the toilet seat 200 on the front side of the opening 200a is set as the front part and the side of the opening 200a is set as the side part, the control device 405 controls the spray device 481 to The amount of water per unit area (average water amount) of the sterilized water in front of the back surface 204 of the toilet seat 200 is smaller than the amount of water per unit area of the sterilized water in the side part of the back surface 204 of the toilet seat 200 The amount of water (average amount of water) is large. By increasing the amount of sterilized water that reaches the front side than the side side, the generation of bacteria and dirt on the back surface 204 of the toilet seat 200 can be further suppressed.

In addition, since the possibility of a user directly contacting the back surface 204 of the toilet seat 200 is lower than that of the surface 203, the back surface 204 of the toilet seat 200 is a portion with a high degree of tolerance to wetting. In addition, on the back surface 204 of the toilet seat 200, urine and sewage splashed by touching the bowl 801 and the stored water 801w are likely to adhere. Therefore, the back surface 204 of the toilet seat 200 is a portion where the dirt load is larger than the surface 203 of the toilet seat 200. In response to this, as shown in FIG. 20, the control device 405 controls the spray device 481 so that the amount of water per unit area of the sterilized water at the back 204 of the toilet seat 200 is greater than at the surface 203 of the toilet seat 200 The amount of water per unit area of the sterilized water is large.

In other words, the amount of the sterilized water that hits the back surface 204 of the toilet seat 200 is greater than the surface 203 of the toilet seat 200. By causing a large amount of sterilized water to be applied to the back surface 204 of the toilet seat 200, the generation of bacteria and dirt can be suppressed.

In addition, as shown in FIG. 20, the amount of water per unit area of the front end area and the side area of the inner wall surface 807 of the basin edge portion 805 is "large", and the amount of water per unit area of the front end area and the side area of the bowl portion 801 The amount of flooding is "large". However, the amount of sterilized water per unit area that directly hits the front end region and the side region of the pot 801 is "medium".

That is, the control device 405 controls the spray device 481 so that the amount of water per unit area (average amount of water) per unit area of the sterilized water that directly hits the inner wall surface 807 of the basin edge 805 is less than the amount of water that directly hits the basin The amount of water per unit area (average water amount) of 801 sterilized water is large. Among them, the amount of sterilized water that directly hits the water does not include the amount of sterilized water that flows down from above.

The wash water for toilet cleaning flows through the bowl portion 801, and the wash water for toilet cleaning does not flow on the inner wall surface 807 of the bowl edge portion 805. Therefore, the dirt load on the inner wall surface 807 of the bowl edge 805 is greater than that of the bowl 801. Therefore, as described above, by making the amount of the sterilized water directly on the inner wall surface 807 of the basin edge portion 805 where the dirt load is relatively large, the generation of bacteria and dirt on the inner wall surface 807 can be further suppressed.

21(a) and 21(b) are perspective views illustrating a method of measuring the particle size of the embodiment. The laser diffraction method is used for the measurement of the particle size. When the particles are irradiated with laser light, diffracted and scattered light in various directions from the particles is generated. The intensity of the diffracted scattered light has a spatial pattern in the direction of light emission. This spatial pattern is called a light intensity distribution pattern. The light intensity distribution pattern changes according to the particle size of fine particles. Using the correlation between the particle diameter of the particles and the light intensity distribution pattern, the particle diameter can be calculated by detecting the light intensity distribution pattern.

As shown in FIGS. 21( a) and 21 (b ), the particle diameter measuring device 600 includes a light emitting unit 601 and a light receiving unit 602. The light receiving unit 602 is provided to be able to receive the laser light emitted by the light emitting unit 601. In the measurement of the particle diameter, the laser light emitted from the light emitting unit 601 is irradiated to the water mist M ejected from the spray device 481. The light receiving unit 602 receives diffracted and scattered light generated by laser irradiation. With this, the light intensity distribution pattern can be detected. Aerotrac LDSA-3500A (manufactured by MicrotracBEL Corporation) can be used as the measuring device.

22(a) and 22(b) are a plan view and a cross-sectional view illustrating a part of a toilet device of a modification of the embodiment. Fig. 22(a) is a plan view of a part of the toilet device viewed from the front. 22(b) is a cross-sectional view taken along line AA shown in FIG. 22(a). As shown in FIGS. 22( a) and 22 (b ), in this example, the water mist baffle 482 is not provided, but a slit S is provided in the housing 400. The spray device 481 is disposed in the housing 400, and the slit S is located in the lower front portion of the spray device 481. For example, the height (position in the vertical direction) of the upper end surface S1 of the slit S is the same as the height of the bottom surface B1 of the disk 481b, and the upper end surface S1 and the bottom surface B1 are on the same plane. Alternatively, the upper end 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 water mist M slightly downward from the horizontal. The water mist M ejected from the disk 481b is ejected into the bowl 801 through the slit S. Thereby, since the water mist baffle 482 as shown in FIG. 5 is not provided, it is possible to prevent dirt Y such as urine from adhering to the spray device 481 without impairing the design and cleanliness of the flushing device.

23 is a block diagram illustrating a configuration of main parts of a toilet flushing device according to a modification of the embodiment. Among them, FIG. 23 shows the main parts of the waterway system and the electrical system. As shown in FIG. 23, in this example, the solenoid valve 431, the sterilization device 450, the switching valve 472, the spray device 481, the nozzle motor 476, the nozzle 473, the nozzle cleaning chamber 478, the flow paths 110 to 113, etc. are assembled in the toilet 800 inside. In this example, the toilet seat motor 511 (rotating device), the toilet lid motor 512 (rotating device), the air blowing device 513, the heater heater 514, and the like are assembled inside the toilet 800. In addition, in this example, a sensor 402 (for example, a human body sensor 403, a seating sensor 404, etc.) and a control device 405 are assembled inside the toilet 800.

In this way, in the example shown in FIG. 3, each component (hereinafter, referred to as a “functional portion”) that is assembled inside the housing 400 of the toilet seat device 100 may be assembled inside the toilet 800. When the functional part is assembled inside the toilet 800, the spray device 481 and the like can be operated in the same manner as when the functional part is assembled inside the housing 400.

In addition, in the case where the functional part is assembled inside the toilet 800 in this way, the housing 400 of the toilet seat device 100 may be omitted. Alternatively, the toilet seat 200 and the toilet lid 300 may be provided instead of the toilet seat device 100. In this case, for example, the toilet seat 200 and the toilet lid 300 are respectively pivotally supported to be freely openable and closable relative to the toilet 800. In this case, for example, the nozzle shutter 479, the water mist shutter 482, and the air supply shutter 516 are pivotally supported relative to the toilet 800.

In the above, the embodiment of the present invention has been described. However, the present invention is not limited to these descriptions. Those skilled in the art appropriately adding design changes to the above-mentioned embodiments are also included in the scope of the present invention as long as they have the characteristics of the present invention. For example, the shape, size, material, arrangement, installation method, and the like of each element included in the toilet, the toilet seat device, and the like are not limited to the examples, and can be appropriately changed. In addition, the elements included in the above-described embodiments can be combined as long as they are technically feasible, and their combination is included in the scope of the present invention as long as the features of the present invention are included.
