Japanese Patent No. 5029930 Japanese Patent Publication No. 2007-138605

As in Patent Literature 1, in order to suppress the occurrence of bacteria and contamination by the germicidal water such as hypochlorous acid water or the like, it is preferable to embark many germicidal water on the target site. For example, by using airflow as in Patent Literature 2, it is considered that many mist-like germicidal waters will be launched on the toilet, toilet seat, and toilet seat cover. In this case, however, a large number of germicidal waters start on the upper surface or toilet seat of the rim of the toilet. When a large number of germs are undertaken on the toilet seat, when the user sits on the toilet seat or when the toilet is rotated by hand, the user's buttocks or hands may come in contact with the germs that have started on the toilet seat and the user may feel uncomfortable. In addition, when a large number of bacteriostatic water starts on the upper surface of the rim of the toilet, there is a fear that the bactericidal water that has impinged on the upper surface of the rim may fall outside the toilet.

The present invention has been made on the basis of the recognition of such a problem, and the germicidal water is in contact with the user's skin and the germicidal water is in contact with the user's skin while suppressing germs and contamination in a wide range of not only the bowl part of the toilet, but also the rim and toilet seat of the toilet It is an object of the present invention to provide a toilet seat apparatus and a toilet apparatus that can prevent falling to the outside.

The first aspect of the present invention provides a toilet seat provided on an upper portion of a toilet, the toilet seat being seated by a user, a disinfecting device for generating germicidal water, and in the state where the toilet seat is installed on the upper portion of the toilet, A spraying device disposed below and spraying mist of the germicidal water toward the toilet, a blower which blows toward the toilet to generate an upward airflow, and controls the sterilizing device, the spraying device and the blowing device And a control device configured to operate the spraying device to spray mist of the germicidal water into the toilet, and operate the blower to raise the mist of the germicidal water to the toilet seat side. And a first step of generating a first rising air stream capable of generating the first rising air stream to the blower. In the second step, the second step of not generating the mist of the germicidal water and not raising the mist of the germicidal water to the toilet seat side is performed at another timing, and the total amount of the mist of the germicidal water sprayed in the first process is And the spraying device is controlled to be less than the total amount of mist of the sterilizing water to be sprayed.

According to this toilet seat apparatus, the mist of the germicidal water sprayed from the lower part than the toilet seat part rises to the toilet seat side by a 1st raised airflow in a 1st process, and rises to the toilet seat side by a 1st raised airflow in a 2nd process. I never do that. Thereby, with a single spraying device, the mist of germicidal water can be launched not only on the bowl part of the toilet but also on the upper surface and the toilet seat part of the rim. The germs and contamination can be suppressed in a wide range such as the toilet bowl and toilet seat as well as the bowl bowl of the toilet bowl.

Moreover, the 1st process which produces the 1st raised airflow which can raise the mist of germicidal water to the toilet seat side, and the 2nd process which does not raise the mist of germicidal water to the toilet seat side without generating a 1st raised airflow are different. By executing at the timing, the impingement amount of the sterilization water in the bowl part, the impingement amount of the sterilization water in the upper surface of the rim part, and the impingement amount of the sterilization water in the toilet seat can be arbitrarily controlled.

Further, by reducing the total amount of the mist of the germ water sprayed in the first step to be less than the total amount of the mist of germ water sprayed in the second step, the amount of the germicidal water impinging on the toilet seat and the upper surface of the rim is relatively small. The amount of germicidal water impinging on the inner wall surface of the bowl portion and the rim portion can be made relatively high. The inner wall surface of the bowl part and the rim part has a large pollution load because dirt is easily attached directly. In addition, the inner wall surface of the bowl portion or the rim portion is a portion having a high tolerance for wetting because it is unlikely to cause inconvenience even when wet. Therefore, the occurrence of bacteria and contamination can be suppressed by initiating a lot of mist of the germicidal water to the bowl portion and the rim portion. On the other hand, the upper surface of the toilet seat portion and the rim portion is a portion where dirt is less likely to attach directly to the inner wall surface of the bowl portion or the rim portion, and the contamination load is small. For this reason, in the upper surface of a toilet seat part and a rim part, microbe and contamination can be suppressed by starting a comparatively small amount of germicidal water. In addition, if the upper surface of the toilet seat or the rim is excessively wet, there is a possibility that the germicidal water may come into contact with the user's skin or fall out of the toilet, and the upper surface of the toilet seat or the rim is a low tolerance for wetting. On the contrary, the upper surface of the toilet seat part and the rim part can be dried in a short time by reducing the amount of water to be disinfected on the upper surface of the toilet seat part and the rim part. As a result, the germicidal water may be prevented from coming into contact with the user's skin or falling out of the toilet.

Thus, according to this toilet seat apparatus, germ water can come into contact with the user's skin and germ water fall outside the toilet while suppressing germs and contamination in a wide range of not only the bowl of the toilet but also the rim and toilet seat of the toilet. It can prevent.

According to a second aspect of the present invention, the second step is a toilet seat apparatus characterized in that the operation of the blower device is stopped.

I never do that. Thereby, with a single spraying device, the mist of germicidal water can be launched not only on the bowl part of the toilet but also on the upper surface and the toilet seat part of the rim. The germs and contamination can be suppressed in a wide range such as the toilet bowl and toilet seat as well as the bowl bowl of the toilet bowl.

Moreover, the 1st process which produces the 1st raised airflow which can raise the mist of germicidal water to the toilet seat side, and the 2nd process which does not raise the mist of germicidal water to the toilet seat side without generating a 1st raised airflow are different. By executing at the timing, the impingement amount of the sterilization water in the bowl part, the impingement amount of the sterilization water in the upper surface of the rim part, and the impingement amount of the sterilization water in the toilet seat can be arbitrarily controlled.

Further, by reducing the total amount of the mist of the germ water sprayed in the first step to be less than the total amount of the mist of germ water sprayed in the second step, the amount of the germicidal water impinging on the toilet seat and the upper surface of the rim is relatively small. The amount of germicidal water impinging on the inner wall surface of the bowl portion and the rim portion can be made relatively high. The inner wall surface of the bowl part and the rim part has a large pollution load because dirt is easily attached directly. In addition, the inner wall surface of the bowl portion or the rim portion is a portion having a high tolerance for wetting because it is unlikely to cause inconvenience even when wet. Therefore, the occurrence of bacteria and contamination can be suppressed by initiating a lot of mist of the germicidal water to the bowl portion and the rim portion. On the other hand, the upper surface of the toilet seat portion and the rim portion is a portion where dirt is less likely to attach directly to the inner wall surface of the bowl portion or the rim portion, and the contamination load is small. For this reason, in the upper surface of a toilet seat part and a rim part, microbe and contamination can be suppressed by starting a comparatively small amount of germicidal water. In addition, if the upper surface of the toilet seat or the rim is excessively wet, there is a possibility that the germicidal water may come into contact with the user's skin or fall out of the toilet, and the upper surface of the toilet seat or the rim is a low tolerance for wetting. On the other hand, in the upper surface of the toilet seat part and the rim part, the upper surface of the toilet seat part and the rim part can be dried in a short time by reducing the impingement amount of the germicidal water. As a result, the germicidal water may be prevented from coming into contact with the user's skin or falling out of the toilet.

In this way, according to the toilet apparatus, the germ water can come into contact with the user's skin and the germ water falls outside the toilet while suppressing germs and contamination in a wide range of not only the bowl of the toilet but also the rim and toilet seat of the toilet. It can prevent.

In particular, in the case of "direct impingement", it means that water (fine particles p of sterilizing water or tap water) arrives on the surface of an object from the air.

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

The toilet seat motor 511 rotates and opens and closes the toilet seat part 200 based on the instruction | command from the control apparatus 405. The toilet lid motor 512 rotates and closes the toilet lid 300 by electric power based on the instruction from the control device 405.

The blower 513 is a fan installed in the casing 400, for example. The blower 513 operates based on the command from the control apparatus 405. For example, the blade rotates in accordance with the rotation of the motor of the blower 513. Accordingly, the blower 513 may blow the air toward the toilet 800 (for example, in the bowl portion 801). In addition, the blower 513 may blow into the local part of the user who sat in the toilet seat part 200. FIG. The warm air heater 514 warms the air sent to the outside of the casing 400 by the blower 513. Accordingly, the hot air can be sent toward the user's local part to dry the local part.

The toilet seat heater 515 (drying apparatus) is installed inside the toilet seat part 200, for example. The toilet seat heater 515 has the annular metal member provided along the periphery of the opening 200a formed in the center of the toilet seat part 200, for example. The electric current is supplied to the toilet seat heater 515 based on the instruction | command from the control apparatus 405, and the toilet seat heater 515 warms the toilet seat part 200. FIG. As the toilet seat heater 515, a tubing heater, a sheath heater, a halogen heater, a carbon heater, etc. may be used, for example. The metal member is made of, for example, aluminum or copper. In addition, the shape of a metal member can employ | adopt various shapes, such as a sheet form, a wire form, and a mesh form.

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

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

In addition, the manual operation part 500 may not only spray the germicidal water, but also have a switch, a button, etc. for a user to operate each function of the toilet seat apparatus 100. When operation corresponding to each function is performed, the operation information is sent to the control apparatus 405, and the control apparatus 405 controls the operation | movement of each part of the toilet seat apparatus 100 based on the operation information.

The seat detection sensor 404 may detect the presence or absence of a seat on the toilet seat 200 of the user. The seat detection sensor 404 detects a seat and a seat of the user. The seating detection sensor 404 can use a microwave sensor, a ranging sensor (infrared light sensor), an ultrasonic sensor, a tact switch, a capacitive switch (touch sensor), or a deformation sensor. In this example, the range sensor installed in the casing 400 is used for the seating detection sensor 404.

In addition, when using contact sensors, such as a tact switch, an electrostatic sensor, and a deformation sensor, these contact sensors are provided in the toilet seat part 200. As shown in FIG. When the user sits on the toilet seat 200, the tact switch is pressed down by the weight of the user. Or, the user contacts the electrostatic sensor. Alternatively, pressure is applied to the deformation sensor by the weight of the user. The user's seat can be detected by the electrical signals from these sensors.

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

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

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

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

4 (a) to 4 (e) are a plan view and a perspective view illustrating the toilet device according to the embodiment.

4 (a) shows a state of a part of the toilet apparatus 10 viewed from the front.

As shown in FIG. 4 (a), the spray device 481, the nozzle damper 479, and the blower damper 516 have the bowl portion 801 in a state where the toilet seat apparatus 100 is installed above the toilet 800. ) Is located at the rear upper part.

FIG. 4B shows an enlarged view of part of FIG. 4A. In addition, in FIG.4 (b), the part of the casing 400 located in front of the spraying apparatus 481 is abbreviate | omitted in order to make it easy to see.

The nozzle damper 479 is axially supported by the casing 400 so that rotation is possible. The nozzle 473 is located behind the nozzle damper 479 in a state of retreating into the casing 400. At the time of washing of a human body part, the nozzle 473 contacts the nozzle damper 479, rotates the nozzle damper 479, and advances from the inside of the casing 400. FIG.

4 (c) to 4 (e) are perspective views showing the periphery of the spraying device 481, the nozzle damper 479, and the blowing damper 516 in an enlarged manner.

The blowing damper 516 is axially supported by the casing 400 so as to be rotatable. A blower 513 is disposed behind the blower damper 516. Blowing damper 516 covers opening 516a of casing 400. Air sent from the blower 513 is sent into the toilet 800 through the opening 516a.

4 (c) is a state in which the blower 513 has stopped operating, and FIGS. 4 (d) and 4 (e) show that the blower 513 operates to blow air toward the bowl 801. Indicates a state of presence.

As shown in FIG.4 (c), the blowing damper 516 is closed in the state which stopped blowing.

As shown in Fig. 4D, when the blower 513 is operated, the blower damper 516 is rotated and opened by the pressure (wind pressure) of the air sent from the blower 513. Accordingly, the blower 513 blows from the rear upper portion in the bowl portion 801 toward the front lower portion in the bowl portion 801 as shown by arrow A1.

In the state of FIG. 4E, compared with the state of FIG. 4D, the air volume sent by the blower 513 is large (or the wind speed is high). In this case, the blowing damper 516 is rotated and opened further compared with the state of FIG. 4 (d). Accordingly, the blower 513 blows from the rear upper portion in the bowl portion 801 toward the front upper portion in the bowl portion 801 as shown by arrow A2.

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

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

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

5B and 5C show enlarged peripheries of the nozzle damper 479 and the mist damper 482. 5B illustrates a state in which the nozzle 473 is retracted into the casing 400. At this time, the nozzle damper 479 is in a closed state and covers the front of the nozzle 473. In addition, the mist damper 482 is in a closed state and covers the front of at least a portion of the spraying device 481.

When the spraying apparatus 481 is not used, the spraying apparatus 481 is concealed from the bowl part 801 side by the mist damper 482 like FIG. 5 (b). Thereby, urine or contamination can be prevented from adhering to the spraying device 481.

5C shows a state in which the nozzle 473 moves forward and the nozzle damper 479 is rotated. The advancing distance to the front of the nozzle 473 at this time may be shorter than the advancing distance to the front at the time of a local body washing | cleaning. For example, the tip of the nozzle 473 is in contact with the nozzle damper 479. In addition, in FIG.5 (c), the mist damper 482 rotates and opens with the nozzle damper 479. As shown in FIG. A part (disc 481b) of the spraying apparatus 481 is exposed to the bowl part 801 side. Accordingly, the spraying device 481 can spray the mist toward the bowl portion 801. For example, as described later with reference to FIG. 23, the spray device 481 may be disposed in the casing 400 without providing the mist damper 482.

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

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

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

As shown in FIG. 6B, water W (tap water or germicidal water generated by the germicidal device 450) is supplied to the upper surface of the disk 481b. During the rotation of the disk 481b, the water W is supplied so that the spraying device 481 sprays the water W into a mist shape. In addition, in this example, although the disk 481b is flat disk shape, you may provide an unevenness | corrugation suitably, and you may use a cone shape or a sphere.

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

In addition, in this specification, particle size is the particle size of the microparticles | fine-particles p which exist in the air before starting to the toilet apparatus 10, and a Sauter average particle diameter (total volume / total surface area) is used. The measuring method of "particle size" in this specification is mentioned later with respect to FIG. In addition, mist refers to the range whose particle diameter is 10 micrometers (micrometer) or more and 300 micrometers or less. If the particle diameter of the mist is less than 10 µm, a long time is required to wet the target sites such as the bowl 801, the rim 805, the toilet seat 200, and the like. In addition, when the bactericidal water containing hypochlorous acid is used, when the particle diameter of mist is less than 10 micrometers, the density | concentration of hypochlorous acid in mist is easy to attenuate, and sterilization performance will fall easily. On the other hand, when the particle size of mist is larger than 300 micrometers, it becomes difficult to diffuse mist and it becomes difficult to spray mist over a wide range. In addition, in the following description, the mistran particle size of a large particle size is 100 micrometers or more and 300 micrometers or less, Preferably it is the mist of the range of 150 micrometers or more and 300 micrometers or less, The mistran particle size of a medium particle diameter is 50 micrometers or more and 200 micrometers or less, Preferably it is the mist of the range of 60 micrometers or more and 150 micrometers or less, and the mistrane particle diameter of a small particle size is the mist of the range of 10 micrometers or more and 100 micrometers or less, Preferably it is 10 micrometers or more and 60 micrometers or less.

7 (a) and 7 (b) are plan views illustrating the disk of the spraying apparatus according to the embodiment.

7A and 7B show the rotating disk 481b seen from above. In the example of FIG. 7A, the number of the water supply ports 481c for supplying the water W on the disk 481b is one. In this case, in the region near the water supply port 481c, the water W is radiated on the disk 481b before the water film of the supplied water W is thinned on the disk 481b. For this reason, as shown to Fig.7 (a), in the circumference | surroundings of the spraying apparatus 481, a bubble uniformity arises in the particle size of mist. In other words, a region R1 having a relatively large particle size of the mist, a region R2 having a medium grain size of the mist, and a region R3 having a relatively small particle size of the mist are formed. Moreover, according to the particle diameter of mist, a nonuniformity arises also in flow volume (amount of mist sprayed in unit time). That is, the flow rate is large in the region R1, the flow rate is medium in the region R2, and the flow rate is small in the region R3.

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

The number of the water supply ports 481c is not limited to one, but a plurality of water supply ports 481c may be provided. For example, four water supply ports 481c are provided in FIG. The water supply port 481c is disposed every 90 degrees when viewed from the center of the disk 481b. In this way, by arranging the plurality of water supply ports 481c at approximately the same interval along the outer circumference of the disk, uniform spraying can be performed while suppressing the particle size of the mist and the unevenness of the flow rate around the spraying device 481.

The spray device 481 is disposed below the toilet seat 200 in a state where the toilet seat apparatus 100 is installed above the toilet bowl 800 (see FIG. 2), and sprays mist into the toilet bowl 800. do. Here, the state where the spraying device 481 is disposed below the toilet seat 200 means that at least a part of the spraying device 481 (the disk 481b in this example) is lower than the toilet seat 200. . Thereby, the mist of tap water or the germicidal water is sprayed in the toilet 800 from below the toilet seat part 200.

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

With reference to FIGS. 8-11, the example of operation | movement of the toilet seat apparatus 100 in an after mist mode and a manual mist mode is demonstrated.

8 (a) and 8 (b) are schematic diagrams illustrating operations in the after-mist mode and the manual mist mode of the toilet seat apparatus according to the embodiment.

The control apparatus 405 performs a 1st process and a 2nd process in one mist mode (one after mist mode or one manual mist mode). FIG. 8A illustrates the first process, and FIG. 8B illustrates the second process.

As shown in Fig. 8 (a), in the first step, the spray device 481 is operated to spray mist of the bactericidal water into the toilet 800, and the blower 513 is operated to operate the first rising air stream. (U1) is generated. The 1st upward airflow U1 is the airflow which can raise the mist of the germicidal water to the toilet seat 200 side.

As shown in FIG. 8 (b), in the second step, the spray device 481 is operated to spray mist of the germicidal water into the toilet 800, and the first raising air flow U1 is blown to the blower 513. ) Does not rise, and the mist of the germicidal water is not raised to the toilet seat 200 side.

By this structure, the mist of the germicidal water sprayed from below the toilet seat 200 rises to the toilet seat 200 side by the 1st raised airflow U1 in a 1st process, and the toilet seat 200 and the rim part The upper surface 806 of 805 is launched. On the other hand, the mist of the germicidal water sprayed from the lower side than the toilet seat 200 does not rise to the toilet seat side by the first rising air flow U1 in the second step, but the mist of the bowl section 801 and the rim section 805 does not rise. The inner wall surface 807 is undertaken. Accordingly, the mist of the germ-free water can be launched on the upper surface 806 or the toilet seat 200 of the rim 805 as well as the bowl 801 of the toilet 800 with a single spray device 418. Therefore, germs and contamination can be suppressed in a wide range such as the bowl portion 801 of the toilet bowl 800 as well as the rim portion 805 and the toilet seat 200 of the toilet bowl 800. In addition, the toilet seat apparatus 100 can be miniaturized by using the single spray apparatus 481.

In addition, the range of "do not raise the mist of germicidal water to the toilet seat side" in a 2nd process may include not only the case where not all the mist rises but also the case where some mist rises. For example, the amount of mist rising to the toilet seat side in the second step is less than the amount of mist rising to the toilet seat side in the first step. In the second step, however, the amount of the bactericidal water to impinge on the toilet seat 200, the upper surface 806 of the rim portion and the toilet lid 300 is preferably as small as possible, for example, preferably zero.

The timing at which the control device 405 executes the first step is different from the timing at which the control device 405 executes the second step. The first step of generating the first rising air flow U1 which can raise the mist of the germicidal water toward the toilet seat 200 side, and the mist of the germicidal water is not generated without generating the first rising air flow U1. By carrying out the second process that does not rise to the side) at different timings, the impingement amount of the sterilizing water in the bowl part 801, the impinging amount of the sterilizing water on the upper surface of the rim part 805, and the toilet seat 200 The impingement amount of the bactericidal water in can be arbitrarily controlled.

Moreover, the control apparatus 405 uses the spraying device 481 so that the total amount g of mist of the germicidal water sprayed in a 1st process may become less than the total amount g of mist of the germicidal water sprayed in a 2nd process. To control. Accordingly, the amount of germicidal water undertaking on the upper surface 806 of the toilet seat 200 and the rim portion 805 is relatively small, and the amount of germicidal water undertaken on the inner wall surface 807 of the bowl portion 801 and the rim portion 805 is relatively low. The amount is relatively large. The generation of bacteria and contamination can be suppressed by initiating a large number of germicidal water mists on the bowl portion 801 and the inner wall surface 807 which have a high pollution load and high tolerance to wetting. In the upper surface 806 of the toilet seat 200 and the rim 805 having a low pollution load and low tolerance to wetness, the toilet seat part ( 200 and the upper surface 806 of the rim 805 may be dried. As a result, the germicidal water can be prevented from coming into contact with the user's skin or falling out of the toilet.

In addition, the total amount of mist is the total amount of mist sprayed by the spraying apparatus 481 in one mist mode (one after mist mode or one manual mist mode). In one mist mode, the spraying apparatus 481 may spray mist continuously, and may spray mist intermittently. In addition, the total amount of mist in a 1st process, and the total amount of mist in a 2nd process are used for adjustment of the rotation speed of the disk 481b, the flow volume of the germicidal water supplied to the spraying device 481, etc., for example. Can be controlled by

For example, the control apparatus 405 controls the spraying device 481 so that the particle diameter of the mist of the germicidal water sprayed during execution of a 2nd process may become larger than the particle diameter of the mist of the germicidal water sprayed during execution of a 1st process. . For example, as shown to Fig.8 (a), the spraying apparatus 481 produces | generates the 1st mist M1 of small particle size during execution of a 1st process. The particle diameter of the first mist M1 (diameter of the fine particles p1 of the bactericidal water) is a particle diameter which can rise to the toilet seat 200 side by the first rising air flow U1. For example, as shown in FIG.8 (b), the spraying apparatus 481 produces the 2nd mist M2 of medium particle diameter during execution of a 2nd process. The particle size of the second mist M2 (diameter of the fine particles p2 of the bactericidal water) is larger than that of the first mist M1.

The total amount of the germicidal water sprayed in the first process can be reduced by reducing the particle size of the mist of the germicidal water sprayed during the execution of the first process. Thereby, the quantity of the germicidal water which impinges on the upper surface 806 of the toilet seat part 200 and the rim part 805 can be reduced reliably. On the other hand, by increasing the particle size of the mist of the germicidal water sprayed during the execution of the second process, the total amount of the germicidal water sprayed in the second process can be increased. Thereby, the quantity of the germicidal water which impinges on the inner wall surface 807 of the bowl part 801 and the rim part 805 can be made large.

For example, the control apparatus 405 stops the operation | movement of the blower 513 in a 2nd process, and does not blow. Thereby, it can prevent more reliably that mist of the germicidal water rises to the toilet seat part 200 side in a 2nd process.

In addition, the control apparatus 405 may generate the 2nd raised airflow U2 by operating the blower 513 in a 2nd process. The flow rate of the 2nd rising air flow U2 is lower than the flow rate of the 1st rising air flow U1, and mist in a 2nd process does not rise to the toilet seat part 200 side by the 2nd rising air flow U2. By the second rising air flow U2, the mist can be diffused horizontally or downwardly without rising to the toilet seat 200 side. Thereby, the germicidal water can be launched in a wider range in the toilet bowl 800.

Moreover, the spraying apparatus 481 sprays radially the mist of the germicidal water when it sees from the upper surface. Radial is a state where the range in which mist exists is widened as it moves away from the spraying apparatus 481. For example, mist is sprayed toward all directions away from the center of the disk 481b in the upper surface.

Since the mist (1st mist M1) in a 1st process is radial, the mist is burned in the whole 1st upstream air flow U1, and the upper surface 806 of the toilet seat 200, the rim part 805, etc. are carried out. It can be launched in a wide range. Moreover, since the mist (second mist M2) in a 2nd process is radial, the toilet 800, such as the inner wall surface 807 of the bowl part 801 and the rim part 805, even if a mist does not burn an airflow. Mist can be launched in a wide range within.

In addition, the diffusion of the mist (first mist M1 and second mist M2), etc., is the rotational speed, arrangement, shape of the disk 481b, and the position of the water supply port 481c for supplying water to the disk 481b. Etc. can be adjusted.

9 (a) and 9 (b) are cross-sectional views illustrating the operation in the first step of the toilet seat apparatus according to the embodiment.

FIG. 9B is an enlarged view of the region R4 shown in FIG. 9A.

The broken arrow indicates the air flow formed by the blower 513. As shown to Fig.9 (a), in the 1st process, the blower 513 blows forward and downward. At least a portion of the air sent from the blower 513 is directed upward with respect to the toilet 800 (in the bowl portion 801 or the inner wall surface 807 of the rim portion 805). Thereby, the rising airflow U1 which winds up from the toilet seat 800 below the toilet seat part 200 to the upper part of the toilet seat part 200 is formed.

The solid arrows indicate the flow of mist sprayed from the spraying device 481. The thickness of the solid arrow corresponds to the amount of germicidal water. The thicker the arrow, the greater the number of germs. In the first process, some mist is emitted from the spraying device 481 toward the inner wall surface 807 of the rim portion. Mist having a relatively small particle diameter starts the upper surface 806 of the rim portion, the toilet seat 200, the toilet seat cover 300, and the like by the rising airflow. Mist with a relatively large particle size may be impinged on the inner wall surface 807 of the bowl portion 801 and the rim portion 805.

In addition, in embodiment, the nozzle 473 is arrange | positioned between the spraying device 481 and the blowing device 513 in the width direction (width direction) of the nozzle 473 (refer FIG. 4). That is, the spraying apparatus 481 is arrange | positioned in the position away from the blower 513 in the left-right direction. Accordingly, the air flow (first rising air flow U1) blown from the blower 513 into the toilet 800 is generated before the first mist M1 having the small particle size rides in the first rising air flow U1. It is possible to suppress the impingement in the toilet 800 by burning in the air flow before the air).

10 (a) to 10 (d) are plan views illustrating the operation in the first step of the toilet seat apparatus according to the embodiment.

In FIG. 10 (a) and FIG. 10 (c), the toilet seat part 200 and the toilet seat cover 300 are omitted for convenience of explanation. The broken arrow indicates the blowing direction of the blower 513. The solid arrows indicate the flow of mist sprayed from the spraying device 481. The thickness of the solid arrow corresponds to the amount of germicidal water. The thicker the arrow, the greater the number of germs. 10 (b) and 10 (d) show the toilet seat 200.

10 (a) and 10 (b) show the shapes when the disk 481b of the spraying device 481 is counterclockwise when viewed from above. In this case, many germicidal waters start on the left side as compared with the right side of the toilet apparatus 10. For example, as shown in Fig. 10 (a), on the upper surface of the rim portion, more germicidal water starts in the left region RL1 than in the right region RR1. For example, as shown in FIG.10 (b), in the toilet seat part 200, more germicidal numbers start in the left side area | region RL2 than the right side area | region RR2.

10 (c) and 10 (d) show the shapes when the disk 481b of the spraying apparatus 481 is clockwise when viewed from the top. In this case, many germicidal waters start on the right side as compared with the left side of the toilet apparatus 10. For example, as shown in FIG.10 (c), in the upper surface of a rim part, many germicides start in the right side area | region RR1 rather than the left side area | region RL1. For example, as shown in FIG.10 (d), in the toilet seat part 200, more germicidal numbers start in the right side area | region RR2 than the left side area | region RL2.

It is preferable that the control apparatus 405 controls the motor 481a of the spraying apparatus 481, and switches clockwise and counterclockwise suitably during a 1st process. As a result, the distribution of mist in the left and right directions tends to be uniform.

11 (a) to 11 (c) are cross-sectional views and plan views illustrating the operation in the second step of the toilet seat apparatus according to the embodiment.

The solid arrows indicate the flow of mist sprayed from the spraying device 481. The thickness of the solid arrow corresponds to the amount of germicidal water. The thicker the arrow, the greater the number of germs. For convenience of explanation, the toilet lid 300 is omitted in FIG. 11A, and the toilet seat 200 and the toilet lid 300 are omitted in FIGS. 11B and 11C. In this example, the control device 405 does not operate the blower 513 in the second step. That is, in the 2nd process, blowing into the toilet bowl 800 is not performed.

As shown in the cross-sectional view of FIG. 11A, the spraying device 481 sprays mist toward the upper end of the rim portion 805. In the second step, the mist of the germicidal water impinges on the bowl portion 801 and the inner wall surface 807 of the rim portion 805. In the second step, since the first rising air flow U1 does not occur, the mist of the germicidal water does not start on the upper surface 806 of the toilet seat 200 or the rim 805, for example.

The top view of FIG. 11 (b) shows the shape when the disk 481b of the spraying apparatus 481 is counterclockwise when viewed from the top. In this case, a greater number of bacteriostatic bacteria are launched on the left side than on the right side in the toilet 800.

The top view of FIG. 11 (c) shows the state when the disk 481b of the spraying apparatus 481 is clockwise in the upper surface. In this case, a greater number of germicidal bacteria are launched on the right side than the left side in the toilet 800.

It is preferable that the control apparatus 405 controls the motor 481a of the spraying apparatus 481, and switches clockwise and counterclockwise suitably during a 2nd process. As a result, the distribution of mist in the left and right directions tends to be uniform.

As described above, the first bactericidal water can be started by the first surface 806, the toilet seat 200, the toilet seat cover 300, and the like of the rim portion 805. In addition, by the second process, the germicidal water can be started on the inner wall surface 807 of the bowl portion 801 and the rim portion 805. From the above, every corner of the toilet apparatus 10 including the rim 805, the toilet seat 200, the toilet seat cover 300, and the like can be sanitized.

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

When the human body detecting sensor 403 detects the user's exit (step S401: Yes), the control device 405 controls the toilet cover motor 512 to close the toilet cover 300 and closes the solenoid valve 431. The motor 481a and the disk 481b of the spraying device 481 are rotated at high speed in the counterclockwise direction (CCW) (step S402). When the solenoid valve 431 is opened, water supply to the disk 481b is started.

The control apparatus 405 maintains the state which the disk 481b rotated at high speed for predetermined time (step S403: No). As a result, the residual water on the disk 481b can be discharged from the disk 481b. At this time, for example, because the mist damper 482 is closed, mist is not sprayed into the toilet 800.

When a predetermined time has elapsed (step S403: Yes), the control device 405 advances the nozzle 473 into the bowl portion 801 by the nozzle motor 476. Thereby, the mist damper 482 opens (step S404).

Thereafter, the control device 405 controls the sterilizing device 450 to start the generation of the sterilizing water, and controls the blower 513 to start the blowing in the toilet 800 (step S405). Thereby, spraying of mist of the germicidal water in the toilet seat 800, the toilet seat part 200, the toilet seat cover 300, etc. is started. The control apparatus 405 maintains the state by which mist of the germicidal water is sprayed from the disk 481b which rotates at high speed counterclockwise for a predetermined time t1 (step S406: No).

When the predetermined time t1 has elapsed (step S406: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spraying device 481 at high speed in the clockwise direction CW (step S407). . The control apparatus 405 maintains the state by which the mist of the germicidal water is sprayed from the disk 481b which rotates at a high speed in a clockwise direction for a predetermined time t1 (step S408: No). For example, step S405-step S408 correspond to a 1st process.

When the predetermined time t1 elapses (step S408: Yes), the control apparatus 405 stops blowing by controlling the blower 513, and makes the motor 481a and the disk 481b clockwise CW. The motor rotates at an intermediate speed (step S409). Thereby, mist is sprayed on the bowl part 801 and the inner wall surface 807 of the rim part, while suppressing the initiation of the mist to the upper surface 806 of the toilet seat part 200 and the rim part. The control apparatus 405 maintains the state in which mist of the germicidal water is sprayed from the disk 481b which rotates in the clockwise direction at a medium speed (t2) (step S410: No).

When the predetermined time t2 elapses (step S410: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spraying device 481 in the counterclockwise direction CCW (step S411). ). The control apparatus 405 maintains the state by which mist of the germicidal water is sprayed from the disk 481b which rotates in the counterclockwise direction at predetermined speed (t2) (step S412: No). For example, step S409-step S412 correspond to a 2nd process.

When the predetermined time t2 elapses (step S412: Yes), the control device 405 controls the sterilizing device 450 to stop the generation of the sterilizing water (step S413).

The tap water is supplied to the disk 481b, and the control device 405 maintains the state where the disk 481b is rotated at a medium speed for a predetermined time (step S414: No). As a result, self-cleaning of the disk 481b is performed. In addition, self-cleaning is an operation of physically cleaning the disk at a rotational speed that does not induce mist. Self-cleaning water may be used for self-cleaning.

When the predetermined time has elapsed (step S414: Yes), the control device 405 closes the solenoid valve 431 (step S415). The control apparatus 405 stops water supply to the disk 481b, and maintains the state in which the disk 481b rotated at the medium speed for a predetermined time (step S416: No). As a result, the residual water on the disk 481b can be removed.

When a predetermined time has elapsed (step S416: Yes), the control device 405 stops the rotation of the motor 481a and the disk 481b and moves the nozzle 473 into the casing 400 by the nozzle motor 476. Retreat. As a result, the mist damper 482 is closed. In addition, the control apparatus 405 turns the toilet seat heater 515 ON (energized state) (step S417).

The control apparatus 405 maintains the state in which the toilet seat heater 515 is ON (step S418: No). Accordingly, the toilet seat 200 may be dried by raising the temperature of the toilet seat 200 and evaporating the germicidal water impinged on the toilet seat 200. In addition, instead of the toilet seat heater 515, the blower 513 and the warm air heater 514 may be driven, and the toilet seat part 200 may be dried by warm air.

When the predetermined time has elapsed (step S418: Yes), the control device 405 turns the toilet seat heater 515 OFF (non-energized state) (step S419). From the above, the after-mist mode ends.

As described above, the control device 405 executes the first step of initiating the mist of the germ-free water on the upper surface 806 of the toilet seat 200 or the rim 805 in one mist mode. Run As a result, the upper surface 806 of the toilet seat 200 or the rim 805 can be dried during the execution of the second process. Therefore, after the one mist mode is finished, the toilet seat 200 or the rim 805 The time until the upper surface 806 is dried can be shortened.

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

When the user operates the manual operation part 500 (step S501: Yes), the control apparatus 405 controls the toilet cover motor 512, closes the toilet cover 300, opens the solenoid valve 431, and sprays. The motor 481a and the disk 481b of the apparatus 481 are rotated at high speed counterclockwise (CCW) (step S502). When the solenoid valve 431 is opened, water supply to the disk 481b is started.

The control apparatus 405 maintains the state which the disk 481b rotated at high speed for a predetermined time (step S503: No). As a result, the residual water on the disk 481b can be discharged from the disk 481b. At this time, for example, because the mist damper 482 is closed, mist is not sprayed into the toilet 800.

When a predetermined time has elapsed (step S503: Yes), the control device 405 advances the nozzle 473 into the bowl portion 801 by the nozzle motor 476. As a result, the mist damper 482 is opened (step S504).

Thereafter, the control device 405 controls the sterilizing device 450 to start the generation of the sterilizing water, and controls the blower 513 to start the blowing in the toilet 800 (step S505). Thereby, spraying of mist of the germicidal water in the toilet seat 800, the toilet seat part 200, the toilet seat cover 300, etc. is started. The control apparatus 405 maintains the state by which mist of the germicidal water is sprayed from the disk 481b which rotates at high speed counterclockwise for a predetermined time t3 (step S506: No).

When the predetermined time t2 has elapsed (step S506: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spraying device 481 in the clockwise direction CW at a high speed (step S507). . The control apparatus 405 maintains the state in which mist of the germicidal water is sprayed from the disk 481b which rotates at high speed clockwise for a predetermined time t3 (step S508: No). For example, step S505-step S508 correspond to a 1st process.

When the predetermined time t3 elapses (step S508: Yes), the control apparatus 405 stops blowing by controlling the blower 513, and makes the motor 481a and the disk 481b clockwise CW. The motor rotates at an intermediate speed (step S509). Thereby, mist is sprayed on the bowl part 801 and the inner wall surface 807 of the rim part, while suppressing the initiation of the mist to the upper surface 806 of the toilet seat part 200 and the rim part. The control apparatus 405 maintains the state by which mist of the germicidal water is sprayed from the disk 481b which rotates in the clockwise direction at predetermined speed (t4) (step S510: No).

When the predetermined time t4 has elapsed (step S510: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spraying device 481 in the counterclockwise direction CCW (step S511). ). The control apparatus 405 maintains the state in which mist of the germicidal water is sprayed from the disk 481b which rotates in the counterclockwise direction at predetermined speed (t4) (step S512: No). For example, step S509-step S512 correspond to a 2nd process.

When the predetermined time t4 elapses (step S512: Yes), the control device 405 controls the sterilizing device 450 to stop the generation of the sterilizing water (step S513).

The tap water is supplied to the disk 481b, and the control device 405 maintains the state where the disk 481b is rotated at an intermediate speed for a predetermined time (step S514: No). As a result, self-cleaning of the disk 481b is performed.

When the predetermined time has elapsed (step S514: Yes), the control device 405 closes the solenoid valve 431 (step S515). The control apparatus 405 stops water supply to the disk 481b, and maintains the state which the disk 481b rotated at the medium speed for a predetermined time (step S516: No). As a result, the residual water on the disk 481b can be removed.

When a predetermined time has elapsed (step S516: Yes), the control device 405 stops the rotation of the motor 481a and the disk 481b and moves the nozzle 473 into the casing 400 by the nozzle motor 476. Retreat. As a result, the mist damper 482 is closed (step S517). From the above, the manual mist mode is terminated. In addition, after the manual mist mode, the user can sanitize the toilet seat 200 by appropriately wiping the germicidal water impinged on the toilet seat 200 with a toilet paper or the like.

In the manual mist mode and the after-mist mode, the control apparatus 405 makes the time which performs a 1st process shorter than the time which performs a 2nd process. For example, in the after-mist mode described with reference to FIG. 12, the predetermined time t1 is shorter than the predetermined time t2. In the manual mist mode described with reference to FIG. 13, the predetermined time t3 is shorter than the predetermined time t4. By shortening the time of the first step, it is possible to reliably reduce the amount of the bactericidal water to impinge on the upper surface 806 of the toilet seat 200 and the rim 805. On the other hand, by lengthening the time of the second step, it is possible to increase the amount of germicidal water impinging on the inner wall surface 807 of the bowl portion 801 and the rim portion 805.

In addition, the control device 405 controls the spraying device so that the time for spraying the sterilizing water in the manual mist mode is longer than the time for spraying the sterilizing water in the after mist mode. For example, the predetermined time t3 described with reference to FIG. 13 is longer than the predetermined time t1 described with reference to FIG. 12. Thereby, the quantity of the germicidal water which starts to the toilet seat part 200 in a manual mist mode can be made larger than the quantity of the germicidal water which starts to the toilet seat part 200 in an after mist mode. As a result, in the manual mist mode, the sterilization water can be properly infiltrated into the toilet paper and the like, and the sterilization performance can be improved. Moreover, when wiping off, the toilet seat part 200 made of resin can be suppressed from being damaged.

For example, a method of changing the impingement amount of the germicidal water by changing the particle diameter of the mist of the germicidal water without changing the time for spraying the germicidal water is also considered. For example, by increasing the particle size, the impingement amount of the sterilizing water can be increased. However, when the particle diameter is increased, there is a fear that the germicidal water becomes difficult to catch the rising air flow. On the other hand, by changing the time to spray the germicidal water, it is possible to increase the amount of the germicidal water to be launched on the toilet seat 200 or the like without changing the particle size. For this reason, the mist of the germicidal water can be easily burned in an upward airflow, and the germicidal water can be spread in a wide range such as the toilet seat 200.

In addition, the control device 405 operates the drying device for drying the toilet seat 200 with the first drying force during or after the after-mist mode is executed. For example, in FIG. 12, the control device 405 operates the toilet seat heater 515 at a first heating amount (first power (watts)) in steps S417 and S418.

On the other hand, the control device 405 does not operate the drying device during or after the execution of the manual mist mode or at a second drying force less than the first drying force. For example, in FIG. 13, the control device 405 does not operate the toilet seat heater 515. Alternatively, the control device 405 may operate the toilet seat heater 515 at a second heating amount (second power (watts)) smaller than the first heating amount. For example, the toilet seat heater 515 raises the temperature of the left surface during or after the execution of the after-mist mode than the temperature of the left surface during or after the execution of the manual mist mode.

In this way, during or after the execution of the after-mist mode, the drying apparatus starts the toilet seat 200 with a relatively large first drying force (for example, the first electric power) to start the toilet seat 200. The drying time of can be shortened. On the other hand, during or after the execution of the manual mist mode, the drying apparatus does not operate or starts the toilet seat 200 by drying the toilet seat 200 with a relatively small second drying force (for example, the second electric power). The drying time of one germicidal water can be lengthened. Thereby, before wiping the germicidal water set out in the toilet seat part 200 with a toilet paper, it is possible to prevent the toilet seat part 200 from drying.

With reference to FIGS. 14-16, the example of the operation | movement of the toilet seat apparatus 100 in a premist mode is demonstrated.

It is a schematic diagram which illustrates operation | movement in the primitive mode of the toilet seat apparatus which concerns on embodiment.

In the pre-mist mode, the control device 405 operates the spraying device 481 to generate mist M3 (mist of sterile water or mist of tap water). In addition, the control apparatus 405 does not generate | occur | produce mist 1 M3 to the toilet seat 200 side, without generating the 1st raised air flow U1 in the state which sprayed the mist M3 to the spraying apparatus 481. FIG. The blower 513 is controlled. In addition, as mentioned above, the 1st upward airflow U1 is the airflow produced by the blower 513, and it is the thing which raises the mist of germicidal water to the toilet seat 200 side in an after mist mode and a manual mist mode. Possible airflow.

In the pre-mist mode, mist sprayed from below the toilet seat 200 does not rise toward the toilet seat 200 side, but starts to the bowl 801 of the toilet bowl 800 or the inner wall surface 807 of the rim 805. do. A water film is formed on the bowl portion 801 or the inner wall surface 807, which makes it difficult to attach contamination. In addition, since the mist does not rise to the toilet seat 200 side, it is possible to suppress the wet of the upper surface 806 of the toilet seat 200 and the rim 805 in the premist mode. Accordingly, when the user seats or rotates the toilet seat 200 by hand immediately after the premist mode, the user's hand or buttocks can be prevented from getting wet.

On the other hand, in the after-mist mode and the manual mist mode, the control apparatus 405 operates the blower 513, and raises the mist of germicidal water to the toilet seat 200 side by the 1st rising airflow U1.

That is, the control apparatus 405 can switch the case where the mist sprayed from the lower part than the toilet seat part 200 is started to the toilet seat part 200, and the case where the mist is not burned in the upward air stream is switched. Accordingly, in a single spraying device 481, the mist of the germ-free water is launched in the toilet 800 and the toilet seat 200 in the after-mist mode and the manual mist mode, and the toilet seat 200 in the pre-mist mode. The mist may be launched in the toilet 800 so as not to soak.

In the pre-mist mode, the range of "do not raise the mist of sterilizing water or the mist of tap water to the toilet seat side" may include not only all the mists that do not rise but also a case where a slight mist rises. . For example, the amount of mist rising to the toilet seat side in the pre-mist mode is less than the amount of mist rising to the toilet seat side in the after-mist mode or the manual mist mode.

For example, in the premist mode, the control device 405 stops the operation of the blower 513 and does not perform the blowing. As a result, the mist can be prevented from rising to the toilet seat 200 side more reliably.

In the mist mode, the control device 405 may operate the blower 513 to generate the raised air flow U3. The flow rate of the rising air flow U3 is lower than the flow rate of the first rising air flow U1, and the mist M3 does not rise to the toilet seat 200 side by the rising air flow U3. The rising airflow U3 can diffuse the mist in the horizontal direction or downward without raising the mist to the toilet seat 200 side. Thereby, the germicidal water can be launched in a wider range in the toilet bowl 800.

In addition, even in the pre-mist mode, the spraying device 481 sprays the mist of the germicidal water or the mist of tap water radially when the upper surface is seen. As a result, even in the mist mode, even in the case where the mist does not burn up the air flow, the mist can be launched in a wide range such as the inner wall surface 807 of the bowl portion 801 and the rim portion 805.

Mist M3 is a mist of medium particle size or large particle size, for example. The particle size of the mist M3 (diameter of the microorganism p3 of the sterilizing water or tap water) is, for example, the particle size of the first mist M1 in the manual mist mode or the after mist mode, and the diameter of the second mist M2. It may be larger than the particle size. As a result, the mist M3 may not rise to the toilet seat 200 side.

15 (a) to 15 (c) are cross-sectional views and plan views illustrating the operation in the primitive mode of the toilet seat apparatus according to the embodiment.

15A to 15C illustrate a state in which the motor 481a of the spraying device 481 is in a medium speed rotation. At this time, the mist sprayed by the spraying device 481 is mist of medium particle diameter. 15A to 15C, the solid arrows indicate the flow of mist sprayed from the spraying device 481. The thickness of the solid arrow corresponds to the amount of germicidal water. The thicker the arrow, the greater the number of germs. 15 (b) and 15 (c), the toilet seat 200 is omitted for convenience of description.

As shown in the cross-sectional view of FIG. 15A, the spraying device 481 sprays mist toward the upper end of the rim portion 805. When the motor 481a is in the medium speed rotation, the outer region RS of the toilet 800 (the bowl portion) is compared with the inner region RU of the toilet 800 (the inner portion 801U of the bowl portion 801). Many sterile water or tap water are impregnated to the outer portion 801S in the 801 and the inner wall surface 807 of the rim 805.

The plan view of FIG. 15B shows the shape when the disk 481b of the spraying device 481 is counterclockwise when viewed from above. In this case, more germicidal water or tap water is imposed on the left side as compared to the right side in the toilet 800.

The plan view of FIG. 15 (c) shows the shape when the disk 481b of the spraying device 481 is clockwise when viewed from the top. In this case, more germicidal water or tap water starts on the right side compared to the left side in the toilet 800.

16A to 16C are cross-sectional views and plan views illustrating the operation of the toilet seat apparatus according to the embodiment in the pre-mist mode.

16A to 16C illustrate a state in which the motor 481a of the spraying device 481 is in low speed rotation. At this time, the mist sprayed by the spraying device 481 is mist of a large particle size. 16A to 16C, the solid arrows indicate the flow of mist sprayed from the spraying device 481. The thickness of the solid arrow corresponds to the amount of germicidal water. The thicker the arrow, the greater the number of germs. In addition, in FIG. 16 (b) and FIG. 16 (c), the toilet seat part 200 is abbreviate | omitted for convenience of description.

When the motor 481a is in low speed rotation, the mist distance of the mist is shortened because the particle diameter of the mist is large and the centrifugal force is also small as compared with the case where the motor is in the medium speed rotation. As shown in the cross-sectional view of FIG. 16A, when the motor 481a is at a low speed rotation, more germicidal water is contained in the inner region RU of the toilet 800 compared to the outer region RS of the toilet 800. Or tap water is undertaken.

The plan view of Fig. 16B shows the shape when the disk 481b of the spraying apparatus 481 is clockwise in view from the top. In this case, more germicidal water or tap water starts on the right side compared to the left side in the toilet 800.

The plan view of FIG. 16C shows the shape when the disk 481b of the spraying device 481 is counterclockwise when viewed from above. In this case, more germicidal water or tap water is imposed on the left side as compared to the right side in the toilet 800.

The control apparatus 405 controls the motor 481a of the spraying apparatus 481, and switches the low speed rotation and the medium speed rotation suitably in the premist mode. Thereby, the mist of sterile water or tap water can be started to every corner of the toilet bowl 800.

In addition, it is preferable that the control device 405 controls the motor 481a of the spraying device 481 and switches clockwise and counterclockwise as appropriate in the premist mode (during low speed rotation and medium speed rotation). . As a result, the distribution of mist in the left and right directions tends to be uniform.

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

When the human body detecting sensor 403 detects a user's entrance (step S301: Yes), the control device 405 controls the toilet cover motor 512 to open the toilet cover 300 to open the solenoid valve 431. The motor 481a and the disk 481b of the spraying device 481 are opened and rotated at an intermediate speed in the counterclockwise direction CCW (step S302). When the solenoid valve 431 is opened, water supply to the disk 481b is started.

The control apparatus 405 maintains the state which the disk 481b rotated at the intermediate speed for a predetermined time (step S303: No). As a result, the residual water on the disk 481b can be discharged from the disk 481b. At this time, for example, because the mist damper 482 is closed, mist is not sprayed into the toilet 800.

When a predetermined time has elapsed (step S303: Yes), the control device 405 advances the nozzle 473 into the bowl portion 801 by the nozzle motor 476. As a result, the mist damper 482 is opened (step S304). Accordingly, spraying of the mist of tap water into the toilet 800 is started. The control apparatus 405 maintains the state by which the mist of tap water is sprayed from the disk 481b which rotates counterclockwise by the medium speed for a predetermined time (step S305: No).

When the predetermined time has elapsed (step S305: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spraying device 481 in the clockwise direction CW (step S306). The control apparatus 405 maintains the state by which the mist of tap water is sprayed from the disk 481b which rotates intermediate speed clockwise for a predetermined time (step S307: No).

When the predetermined time passes (step S307: Yes), the control apparatus 405 rotates the motor 481a and the disk 481b of the spraying device 481 in the clockwise direction CW (step S308). The control apparatus 405 maintains the state by which mist of tap water is sprayed from the disk 481b which rotates at low speed clockwise for a predetermined time (step S309: No).

When the predetermined time has elapsed (step S309: Yes), the control device 405 rotates the motor 481a and the disk 481b of the spraying device 481 at low speed in the counterclockwise direction (CCW) (step S310). The control apparatus 405 maintains the state by which the mist of tap water is sprayed from the disk 481b which rotates counterclockwise at predetermined speeds (step S311: No).

When the predetermined time elapses (step S311: Yes), the control device 405 closes the solenoid valve 431 (step S312). The control apparatus 405 stops water supply to the disk 481b, and maintains the state which the disk 481b rotated at low speed for a predetermined time (step S313: No). As a result, the residual water on the disk 481b can be removed.

When a predetermined time has elapsed (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 into the casing 400. Retreat. As a result, the mist damper 482 is closed (step S314). From the above, the mist mode is terminated.

The control apparatus 405 executes the primitive mode with the toilet lid 300 open. That is, in the mist mode, mist is sprayed in the state in which the toilet lid 300 is opened. Accordingly, the user can immediately sit in the toilet seat 200 without waiting for execution of the premist mode. Further, in the premist mode, the spraying device 481 sprays the mist so that the mist does not impinge on the toilet seat 200, even if the user sits on the toilet seat 200 during the execution of the premist mode. As a result, the chance of mist reaching the user is low.

On the other hand, the control device 405 executes the after-mist mode and the manual mist mode in a state where the toilet seat cover 300 is closed. That is, in the after-mist mode and the manual mist mode, mist is sprayed while the toilet lid 300 is closed. As a result, the mist of the germicidal water is prevented from scattering to the outside of the toilet, while the mist of the germicidal water is diffused to prevent germs and contamination in a wide range of the toilet bowl 800, the toilet seat 200, the toilet lid 300, and the like. It can be suppressed.

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

19 (a) and 19 (b) are schematic diagrams illustrating the operation of the toilet seat apparatus according to the embodiment.

Fig. 19 (b) shows the target sites P1 to P4 to which the mist of the bactericidal water or tap water starts. In each mist mode, Fig. 19 (a) shows the impingement amount (the impinging amount per unit area) of each target site in four stages of "large", "medium", "small", and "minimal".

In the pre-mist mode, after the detection sensor 402 does not detect the user, the user detects the user, and the mist or tap water of the germicidal water is automatically prevented so that the germicidal water or the tap water does not impinge on the toilet seat 200. Mist is sprayed into the toilet (800).

For example, as shown in FIG. 18, when a user enters a toilet and the human body detection sensor 403 detects a user's entrance, the signal (detection information) which shows the user's entrance is transmitted to the control apparatus 405. As shown in FIG. The control device 405 automatically executes the primitive mode based on the signal. In the pre-mist mode, the control device 405 sprays mist of tap water onto the spraying device 481 to launch the mist at the target site. The target site | part in the primitive mode is target site | part P3 (inner wall surface 807 of the rim part 805), and target site | part P4 (bowl part, as shown to FIG. 19 (a) and FIG. 19 (b)). (801)). In the primitive mode, the upper surface 806 of the toilet seat 200 and the rim 805 is not the target site of spraying.

As such, prior to the use of the toilet seat apparatus 100, the sterilizing water or tap water is started in the toilet 800 by the premist mode. As a result, a water film may be formed in the toilet 800 having a high pollution load and a high tolerance for wetting, thereby preventing the fixing of dirt. On the other hand, in the upper surface 806 of the toilet seat 200 or the rim portion 805 having a small pollution load, even after the use of the toilet seat apparatus 100, the germicidal water is removed after the toilet seat apparatus 100 is used. Sedimentation of the dirt can be suppressed by initiating. Thus, in the toilet seat apparatus 100, in the mist mode, the toilet 800 sprays the mist of the sterilizing water or the tap water so as not to settle on the toilet seat 200. Accordingly, the germ water or the tap water sprayed by the mist mist mode is suppressed by the mist mist mode and the after mist mode while suppressing the occurrence of bacteria and contamination in a wide range such as the toilet bowl 800 or the toilet seat 200. The user can be prevented from getting wet. For example, even when the user rotates the toilet seat 200 by hand or seats on the toilet seat 200 immediately after the execution of the premist mode, the germ water or tap water of the user's buttocks or hands under the toilet seat. Can be prevented from contacting That is, the user does not get wet with the mist and can immediately use the toilet seat apparatus 100.

In addition, in the mist mode, the water film can be formed in the toilet 800 in a short time by not initiating a mist in the toilet seat 200, and the execution time of the mist mist mode can be shortened. A user who enters the bathroom may use the toilet seat apparatus 100 without waiting for the termination of the premist mode.

In addition, the range of "the germicidal water or the tap water does not embark on the toilet seat part" in the pre-mist mode is not only when all the mist does not embark on the toilet seat part 200, but a slight mist is started on the toilet seat part 200. You may include the case to do. For example, the amount of tap water or germicidal water undertaking to the toilet seat 200 in the premist mode is less than the amount of germicidal water undertaking to the toilet seat 200 in the after-mist mode or the manual mist mode. However, in the primist mode, the amount of the bactericidal water or the tap water impinging on the toilet seat 200 is preferably as small as possible, for example, it is preferable to be zero.

In the after-mist mode, after the detection sensor 402 is in the state of not detecting the user, the mist of sterile water is automatically sprayed into the toilet 800 and the toilet seat 200.

For example, as shown in FIG. 18, when the user leaves the toilet and the human body detection sensor 403 detects the user's leaving, a signal (detection information) indicating the user's leaving is transmitted to the control device 405. FIG. The control device 405 automatically executes the after-mist mode based on the signal. In the after-mist mode, the control apparatus 405 produces | generates the germicidal water in the germicidal apparatus 450, sprays the mist of the germicidal water into the spraying apparatus 481, and starts mist in a target site | part. As for the target site | part in the after-mist mode, as shown to FIG. 19 (a) and FIG. 19 (b), target site | part P1 (surface 203 of the toilet seat part 200) and target site | part P2 (seat part The back surface 204 of 200 and the top surface 806 of the rim 805), the target site P3, and the target site P4.

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

In addition, since the after-mist mode is performed after the user's toilet seat apparatus 100 is used, it is easy to ensure a long unused time compared with before use. Therefore, even if the upper surface 806 of the toilet seat 200 and the rim part 805 is wet by the after-mist mode, the upper surface 806 of the toilet seat 200 and the rim part 805 tends to be dried until next use.

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

For example, as shown in FIG. 18, when a user operates the manual control part 500 while entering a restroom (for example, after execution of a primitive mode), the signal (operation information) according to an operation will become a control apparatus ( 405). The control device 405 executes the manual mist mode based on the signal. The manual mist mode is executed at the timing of the toilet seat apparatus 100 before use, after use, and when cleaning. In the manual mist mode, the control apparatus 405 generates the germicidal water in the germicidal apparatus 450, sprays the mist of the germicidal water into the spray apparatus 481, and starts the mist at the target site. The target site | part in the passive mist mode is the target site | part P1, the target site | part P2, the target site | part P3, and the target site | part P4, as shown to FIG. 19 (a) and FIG. 19 (b).

In this manner, the germ-free water can be suppressed in the toilet 800 and the toilet seat 200 by the manual mist mode to further suppress the occurrence of bacteria and contamination. For example, against fixation contamination that is difficult to be suppressed by the after-mist mode, the sterilized water undertaken can be sterilized by wiping with a toilet paper or the like. The user can easily wipe the germs without using the dedicated sterilization paper.

In addition, for example, a user who is concerned about contamination of the toilet seat 200 before using the toilet seat apparatus 100 may sterilize the toilet seat 200 by a manual mist mode. Since sterilization is performed based on the user's own operation, the user's security and satisfaction can be enhanced.

As shown in FIG. 18, the control apparatus 405 performs the manual mist mode in the state in which the detection sensor detects a user, and after the said detection sensor detects a user, Even after that, it will run after-mist mode. As a result, even when the manual mist mode is executed before the user's toilet seat apparatus 100 is used (stool or urination), it is possible to reliably suppress the occurrence of bacteria and contamination by executing the after mist mode.

However, if the user leaves the toilet immediately after the end of the manual mist mode, there is a possibility that the germicidal water impinged on the upper surface 806 of the toilet seat 200 or the rim 805 may not be wiped off. For example, when the manual mist mode is executed after the use of the toilet seat apparatus 100 as shown in FIG. 18 and the detection sensor does not detect a user within the first predetermined time T1 from the end of the manual mist mode. There is a possibility that the germicidal water remains on the upper surface 806 of the toilet seat 200 or the rim 805.

Therefore, the control device 405 may not execute the after-mist mode when the detection sensor is not detecting the user from the state in which the detection sensor detects the user within the first predetermined time T1 from the end of the manual mist mode. . Alternatively, the control device 405 is a state in which the detection sensor detects a user after the first predetermined time T1 has elapsed from the end of the manual mist mode in the after mist mode in the after mist mode. In comparison with the case where the user is not detected from the above, the number may be reduced. Thereby, in the after-mist mode, the upper surface 806 of the toilet seat 200 and the rim part 805 can be wetted, and it can prevent that the germicidal water falls out of the toilet bowl. The first predetermined time T1 is, for example, about 10 seconds to 30 seconds. However, the first predetermined time T1 is not limited to this and can be appropriately set.

In addition, immediately after the end of the after-mist mode, when the next user enters the restroom, there is a possibility that the upper surface 806 of the toilet seat 200 or the rim portion 805 is wet with germicidal water. For example, when the next user enters the toilet within the second predetermined time T2 from the end of the after-mist mode and operates the manual operation unit 500, the upper surface 806 of the toilet seat 200 or the rim portion 805 There is a possibility that the germicidal water remains.

Thus, the control device 405 may not execute the manual mist mode when the manual operation unit 500 is operated within the second predetermined time T2 from the end of the after mist mode. Alternatively, when the manual control unit 500 is operated after the second predetermined time T2 has elapsed from the end of the after-mist mode, the control device 405 controls the amount of germicidal water sprayed by the spraying device 481 in the manual mist mode. In comparison with, it may be less. Accordingly, the top surface 806 of the toilet seat 200 or the rim 805 may be too wet by the manual mist mode, thereby preventing the germicidal water from falling 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 is the amount of bacteria to be launched in the toilet seat 200 in the after mist mode (average impingement amount) per unit area of the bacteria to be launched in the toilet seat 200 in the manual mist mode. The spraying device is controlled to be larger than the impingement amount of the sterilization water per unit area (average impingement amount). For example, as shown to Fig.19 (a), in the passive mist mode, the quantity of the germicidal number per unit area which starts to the target site | part P1 and the target site | part P2 is "small". In addition, in the after-mist mode, the quantity of the germicidal number per unit area which starts to the target site | part P1 is "minimum", and the quantity of the germicidal number per unit area which starts to the target site | part P2 is "small".

As described above, since the amount of germicidal water impinging on the toilet seat 200 in the after mist mode is relatively small, the toilet seat 200 can be dried in a short time after the after mist. Thereby, even when a user uses the toilet seat apparatus 100 after an after mist, it can prevent that the germicidal water contacts a hand or a buttocks of a user. In addition, in the manual mist mode, since the amount of the germicidal water impinging on the toilet seat 200 is relatively large, it is possible to properly infiltrate the germicidal water in the toilet paper or the like. Thereby, while improving the disinfection performance by wiping, it can suppress that the toilet seat 200 made of resin is damaged when wiping. Therefore, the drying performance in an after mist mode and the wiping performance in a manual mist mode are compatible.

In addition, as shown to Fig.19 (a), in the manual mist mode and the after mist mode, the quantity of the germicidal number per unit area which starts to the target site | part P3 and the target site | part P4 is "large". On the other hand, the amount of bactericidal bacteria per unit area undertaken at the target site P3 and the target site P4 in the premist mode is "medium". After use of the toilet seat apparatus 100, the generation | occurrence | production of a germ | microorganism and a contamination can be suppressed more by starting many germicide water in the toilet bowl 800.

For example, the control device 405 controls the spraying device so that the particle size of the mist of the sterilizing water sprayed in the after-mist mode is smaller than the particle size of the mist of tap water (or sterilizing water) sprayed in the pre-mist mode. . Further, the control device 405 controls the spraying device so that the particle size of the mist of the sterilizing water sprayed in the manual mist mode is smaller than the particle size of the mist of tap water (or sterilizing water) sprayed in the premist mode.

In this manner, in the after-mist mode and the manual mist mode, by reducing the particle size of the mist, the mist of the bactericidal water is easily diffused in a wide range. As a result, bacteria and contamination can be suppressed in a wide range of the rim portion 805, the toilet seat 200, and the like, as well as the bowl portion 801. In the mist mist mode, the water film can be formed on the inner wall surface 807 of the bowl portion 801 and the rim portion 805 by increasing the particle size of the mist. Accordingly, the user can exit the premist mode before the user sits on the toilet seat.

In the embodiment, the control device 405 includes the amount of impingement per unit area of the germicidal water in the toilet seat 200 in one mist mode (for example, one after mist mode), and the rim portion 805. Each of the amount of impingement per unit area of the sterilization number on the upper surface 806 is smaller than the amount of impingement per unit area of the sterilization number in the bowl portion 801, and the germization on the inner wall surface 807 of the rim portion 805 is performed. The spraying device 481 is controlled to be smaller than the amount of impingement per unit area of the water.

That is, according to the embodiment, in one mist mode, the control apparatus 405 makes the amount of germicidal water which impinges on the inner wall surface 807 of the bowl part 801 and the rim part 805 relatively large. The generation of germs and contamination can be suppressed by initiating a large number of germicidal water mists on the inner wall surface 807 of the bowl portion 801 and the rim portion 805 having a high pollution load and high tolerance to wetting.

In addition, according to the embodiment, in one mist mode, the control apparatus 405 makes the amount of germicidal water which impinges on the upper surface 806 of the toilet seat 200 and the rim part 805 comparatively small. Since the upper surface 806 of the toilet seat 200 and the rim 805 has a relatively small pollutant load, bacteria and contamination can be suppressed by initiating a relatively small amount of germicidal water.

In addition, in the upper surface 806 of the toilet seat 200 or the rim 805 having low tolerance to wetting, the upper surface of the toilet seat 200 or the rim 805 in a short time by reducing the impingement amount of the germicidal water ( 806 may be dried. As a result, the germicidal water may be prevented from coming into contact with the user's skin or falling out of the toilet.

As described above, according to the embodiment, the germicidal water contacts the user's skin while suppressing bacteria and contamination in a wide range of the rim portion 805 and the toilet seat 200 as well as the bowl portion 801 of the toilet bowl. It can prevent the generation and the sterilization water fall out of the toilet.

For example, the control apparatus 405 starts the toilet seat 200 by the amount of impingement (the impingement amount per unit area of the germicidal water in the toilet seat part) in the toilet seat 200 in one mist mode. The spraying device 481 is controlled so that the amount of impingement that the germicidal water remains without dripping off. In addition, in one mist mode, the control apparatus 405 has the impingement amount (the impingement amount per unit area of the germicidal water in the upper surface 806 of the rim part 805) of the rim part 805 in one mist mode. The spraying device is controlled so that the amount of immunization remaining on the upper surface 806 can be retained without dropping.

In this way, since the germicidal water stays on the upper surface 806 of the toilet seat 200 or the rim 805 with a small load of contamination, the time for oxidative decomposition or bleaching of the germicidal water can be secured. It is possible to suppress the occurrence of bacteria and contamination. In addition, by setting the amount of impingement on the upper surface 806 of the toilet seat 200 or the rim 805 to be the amount of impingement where the bactericidal water resides, the risk of the germicidal water flowing out of the toilet can be reduced.

In addition, the control apparatus 405 has the number of germs that the impingement amount (the impingement amount per unit area of the sterilization number in the bowl portion) in the bowl portion 801 impinging on the bowl portion 801 in one mist mode. The spraying device 481 is controlled so that the amount of impingement dripping off. In addition, the controller 405 has a rim portion 805 in which the amount of impingement on the inner wall surface 807 of the rim portion 805 (the impinging amount per unit area of the bactericidal water on the inner wall surface of the rim portion) is in one mist mode. The spraying apparatus 481 is controlled so that the amount of impingement which the germicidal water which has embarked on the inner wall surface 807 of () drips.

In this manner, in the bowl portion 801 or the inner wall surface 807 of the rim portion 805 having a large load of contamination, drops of the germicidal water are dropped, thereby not only oxidizing or bleaching, but also washing the dirt with the germicidal water. Action can be used. Thereby, generation | occurrence | production of a microbe and contamination can be suppressed more effectively than when the germicidal water stays.

In addition, "dropping" means that water (for example, bactericidal water) adhering to the surface of an object flows down. The ranges of "drops falling" include those in which water droplets and water films flow by their own weight, or vibrations due to the operation of the toilet device.

For example, the control apparatus 405 is the germ-infection which started the toilet seat part 200 when the toilet seat amount of the toilet seat part 200 rotated by the toilet seat motor 511 (rotating device). The spraying device is controlled so that the amount of impingement water stays without dripping.

As a result, even when the toilet seat 200 is rotated, since the germicidal water can be prevented from dropping, the action time of the oxidative decomposition and the bleaching action of the germicidal water can be ensured for a long time, so that germs and contamination are generated. Can be suppressed more. In addition, by setting the amount of impingement in the toilet seat 200 to the amount of impingement in which the germicide water stays, the risk of the germ water flowing down to an unintended site can be reduced.

Control of the amount of impingement as described above is possible by control of the particle diameter of the mist sprayed from the spraying device 481. For example, the control device 405 is each of the particle diameter of the mist of the germ water sprayed to the toilet seat 200 and the particle diameter of the mist of the germ water sprayed to the upper surface 806 of the rim portion 805. The spraying device 481 is controlled to be smaller than the particle diameter of the mist of the bactericidal water sprayed to the 801 and smaller than the particle diameter of the mist of the germicidal water sprayed to the inner wall surface 807 of the rim portion 805. In addition, the particle diameter of the mist of the germicidal water sprayed to each site | part is the particle diameter of the mist which starts to each site | part, for example.

Since the particle diameter of the mist of the germicidal water impinging on the upper surface 806 of the toilet seat 200 and the rim part 805 is small, it can make it difficult to drift the germicidal water which started on the upper surface of the toilet seat part and the rim part. In addition, the particle diameter of the mist of the germicidal water impinging on the inner wall surface 807 of the bowl portion 801 and the rim portion 805 is large, so that the inner wall surface 807 of the bowl portion 801 and the rim portion 805 is launched. The germicidal water can be easily dripped, thereby improving the effect of washing away the contamination.

With reference to FIG.20 (a)-FIG.20 (e), the measuring method of an impingement amount (average impingement amount) is demonstrated.

20 (a) to 20 (e) are plan views illustrating the toilet device according to the embodiment.

20A and 20B show the 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 on which the user is seated and faces upward in the closed position 200. The back surface 204 is a surface on the opposite side to the surface 203 and faces downward in a closed state of the toilet seat 200.

As shown to Fig.20 (a), the surface 203 has the front end area | region 203F located in the front side, the side area | region 203R located in the right side, and the left side in the state in which the toilet seat part 200 was closed. It has lateral area 203L located in a room. The area of each area shall be 20 square centimeters (cm <2>).

Impingement amount per unit area (g / cm 2) in the tip region 203F, impingement amount per unit area (g / cm 2) in the lateral region 203R, and impingement amount per unit area in the lateral region 203L The average of (g / cm 2) is taken as the amount of impingement per unit area (average impingement amount (g / cm 2)) on the surface 203.

As shown in FIG.20 (b), the back surface 204 has the front end area | region 204F located in the front side, the side area | region 204R located in the right side, and the left side in the state in which the toilet seat part 200 was closed.

Impingement amount per unit area (g / cm 2) in the tip region 204F, impingement amount per unit area (g / cm 2) in the lateral region 204R, and impingement amount per unit area in the lateral region 204L. The average of (g / cm 2) is taken as the amount of impingement per unit area (average impingement amount (g / cm 2)) on the back surface 204.

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

As shown in FIG.20 (c), the upper surface 806 of the rim part 805 is the front end area | region 806F located in the front side, the side area | region 806R located in the right side, and the side located in the left side. Has an area 806L. The area of each area shall be 20 square centimeters (cm <2>).

The impinging amount per unit area (average impinging amount (g / cm 2)) on the upper surface 806 of the rim portion 805 is the impinging amount per unit area (g / cm 2) and the lateral area 806R in the tip area 806F. ) Is the average of the amount of impingement per unit area (g / cm 2) and the amount of impingement per unit area (g / cm 2) in the lateral region 806L.

As shown in FIG. 20 (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 left side positioned on the inner wall surface 807. It has a lateral area 807L. The area of each area shall be 20 square centimeters (cm <2>).

The impingement amount per unit area (average impingement amount (g / cm 2)) in the inner wall surface 807 of the rim portion 805 is the impingement amount per unit area (g / cm 2) and the lateral area ( It is an average of the amount of impingement per unit area (g / cm 2) in 807R) and the amount of impingement per unit area (g / cm 2) in the lateral region 807L.

As shown in FIG. 20 (e), the bowl portion 801 (the portion of the inner surface of the bowl portion 801 on which no solids are installed) is located at the front end region 801F located at the front side and on the right side. It has a side region 801R located and a side region 801L located in the left side. The area of each area shall be 20 square centimeters (cm <2>).

The amount of impingement per unit area (average impingement amount (g / cm 2)) in the bowl portion 801 is the amount of impingement per unit area (g / cm 2) and the lateral area 801R in the tip area 801F. It is the average of the amount of impingement per unit area (g / cm 2) and the amount of impingement per unit area (g / cm 2) in the lateral region 801L.

In each of the regions 203F, 203L, 203R, 204F, 204L, 204R, 806F, 806L, 806R, 807F, 807L, 807R, 801F, 801L and 801R shown in Figs. 20A to 20E. The measurement of the amount of impingement per unit area is as follows.

First, after spraying mist, the area | region of a predetermined area is wiped off with paper, and the mist which started in the said area is absorbed by paper. Next, the difference between the weight of the paper before the water supply and the weight of the paper after the water supply is the amount of the mist (initiation amount) undertaken in the region. By dividing the amount of impingement by the area (polished area) of the area, the amount of impingement per unit area in the area is calculated.

21 is a table illustrating the amount of impingement of mist in the after mist mode.

In FIG. 21, the magnitude relationship of the impingement amount per unit area in each area | region shown to FIG. 20 (a)-FIG. 20 (e) is shown by four steps of "large", "medium", "small", and "minimal".

For example, the amount of impingement per unit area in the leading region and the lateral region of the upper surface 806 of the rim portion 805 is "medium". In contrast, the amount of impingement per unit area in the front end region and the lateral region of the surface 203 of the toilet seat 200 is "minimal".

That is, the control device 405 is such that the impingement amount per unit area of the sterilization number on the upper surface 806 of the rim portion 805 becomes larger than the impinging amount per unit area of the sterilization number on the surface 203 of the toilet seat 200. The spray device 481 is controlled. Compared with the surface 203 of the toilet seat 200 in which the user is in direct contact, the rim portion 805 is formed by the large amount of antibacterial water on the upper surface 806 of the rim 805 which is less likely to be in direct contact with the user. Occurrence of bacteria and contamination on the upper surface 806 of the () can be suppressed.

In addition, when the user urinates while seated on the toilet seat 200, the front side of the rear surface 204 of the toilet seat 200 easily touches the bowl 801 or the sluice 801w, and is easily attached to splattered urine or sewage. . For this reason, the front side of the back surface 204 of the toilet seat part 200 is a part with a large pollution load compared with the side side of the back surface 204 of the toilet seat part 200. On the other hand, as shown in FIG. 21, the impingement amount per unit area in the front end area | region of the back surface 204 of the toilet seat part 200 is "large", and is located in the side area | region of the back surface 204 of the toilet seat part 200. As shown in FIG. The amount of impingement per unit area of is "small".

That is, in the case where the front side is set to the front portion and the lateral side of the opening 200a is the side portion than the opening 200a of the toilet seat 200, the control device 405 is the rear surface of the toilet seat 200 ( The amount of impingement per unit area (average impingement amount) of the number of germs at the front part of 204) is greater than the amount of impingement per unit area (average impulse amount) of the number of germs at the lateral part of the rear surface 204 of the toilet seat 200. The spraying device 481 is controlled to increase. In comparison with the lateral side, by increasing the amount of germicidal water impinging on the front side, generation of germs and contamination on the back surface 204 of the toilet seat 200 can be further suppressed.

In addition, compared with the surface 203, since the user is unlikely to directly contact the back surface 204 of the toilet seat 200, the back surface 204 of the toilet seat 200 has a high tolerance for wetting. to be. In addition, the back surface 204 of the toilet seat 200 easily touches the bowl portion 801 or the slump 801w and adheres to splattered urine or sewage. For this reason, compared with the surface 203 of the toilet seat part 200, the back surface 204 of the toilet seat part 200 is a part with a big pollution load. On the other hand, as shown in FIG. 21, the control apparatus 405 has the amount of bactericides per unit area of the bactericidal water in the back surface 204 of the toilet seat 200 in the surface 203 of the toilet seat 200. The spraying device 481 is controlled to be larger than the amount of impingement per unit area of.

That is, the amount of germicidal water impinging on the back surface 204 of the toilet seat 200 is large compared with the surface 203 of the toilet seat 200. By increasing the amount of germicidal water impinging on the back surface 204 of the toilet seat 200, it is possible to suppress the occurrence of bacteria and contamination.

As shown in FIG. 21, the amount of impingement per unit area in the distal end region and the lateral region of the inner wall surface 807 of the rim portion 805 is "large", and in the distal region and the lateral region of the bowl portion 801. The amount of undertaken per unit area of is "large". However, the amount of germicidal water per unit area directly impinging on the tip region and the lateral region of the bowl portion 801 is "medium".

That is, the control device 405 is a per unit area of the germicidal water in which the impingement amount (average impingement amount) per unit area of the sterilizing water directly undertaken on the inner wall surface 807 of the rim portion 805 directly undertakes the bowl portion 801. The spraying apparatus 481 is controlled to be larger than the amount of water (average impingement amount). In addition, the impingement amount of the sterilization water which starts directly does not contain the quantity of the sterilization water which flows from upper direction.

Toilet bowl cleaning water flows into the bowl portion 801, and toilet bowl cleaning water does not flow into the inner wall surface 807 of the rim portion 805. For this reason, the inner wall surface 807 of the rim part 805 has a large pollution load compared with the bowl part 801. FIG. Therefore, as described above, by increasing the amount of germicidal water directly impinging on the inner wall surface 807 of the rim portion 805 having a relatively large pollution load, it is possible to further suppress the occurrence of germs and contamination on the inner wall surface 807. Can be.

22 (a) and 22 (b) are perspective views illustrating the method for measuring the particle size according to the embodiment.

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

As shown in FIG.22 (a) and FIG.22 (b), the particle size measuring apparatus 600 has the light emitting part 601 and the light receiving part 602. FIG. The light receiving unit 602 is provided to receive a laser generated by the light emitting unit 601. In the measurement of the particle diameter, the laser generated by the light emitting part 601 is irradiated to the mist M sprayed from the spraying device 481. The light receiving unit 602 receives the diffracted scattered light generated by the laser irradiation. Accordingly, the light intensity distribution pattern can be detected. Aerotrac LDSA-3500A (manufactured by MicrotracBEL Corp.) may be used as the measuring device.

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

The upper surface of the disk 481b is inclined horizontally, and the disk 481b sprays the mist M downwardly rather than horizontally. The mist M sprayed from the disk 481b passes through the slit S and sprays into the bowl 801. Accordingly, since the mist damper 482 is not provided as shown in FIG. 5, it is possible to prevent contamination (Y) such as urine from being attached to the spray device 481 without impairing the design and cleaning properties of the toilet device. It can prevent.
