  Next, a first embodiment in which the toilet seat device of the present invention is embodied will be described with reference to the drawings.

<Example 1>
The toilet seat apparatus 1 of Example 1 is provided with the toilet seat 3 shown in the bottom view of FIG. The toilet seat 3 is arranged on the upper part of the toilet body 5 as shown in a sectional view in FIG. 3 (a sectional view taken along the line II in FIG. 1). As shown in FIG. 1, the toilet seat 3 has a substantially circular opening 7 that is slightly longer in the front-rear direction. The toilet seat 3 has an annular portion 9 around the opening 7 for seating with a predetermined width. A casing 11 is provided at a rear position of the toilet seat 3 (downward position in FIG. 1) (see FIG. 1). As shown in FIG. 1, a water supply valve device 13 of a toilet seat cleaning device is accommodated in the casing 11. The casing 11 is configured to be openable and closable for maintenance.

  As shown in FIG. 1, water discharge ports 17 are formed on the inner peripheral edge 15 of the lower surface 3 </ b> A of the toilet seat 3 over substantially the entire periphery of the inner peripheral edge 15. The water discharge port 17 is formed with a flat slit 17A that is thin in the vertical direction (thickness direction) and wide in the width direction. It is set as the structure which can discharge water in the shape of a thin film by the slit 17A. The water discharge port 17 is connected to the water supply valve device 13 in the casing 11 by a connecting pipe 19. When water is supplied from the water supply valve device 13, water is distributed to the water outlet 17 through the connecting pipe 19, and water is discharged from the water outlet 17. The arrows in FIG. 1 indicate the direction of water discharge, and schematically show how water is discharged radially from the inside of the toilet seat 3 to the outside.

  A preferred arrangement of the spout 17 will be described with reference to FIG. The position of the water discharge port 17 is preferably installed at the inner periphery 15 of the toilet seat 3 or in the vicinity of the inner periphery 15 (within 40 mm, preferably within 20 mm) from the inner periphery 15 as shown by the oblique lines in FIG. If the water discharge port 17 is disposed at a position away from the inner peripheral edge 15 and water is discharged from the water discharge port 17 toward the outside, the inner side than the position of the water discharge port 17 cannot be washed. In the first embodiment, as shown in FIG. 1, a wide range of the lower surface 3 </ b> A of the toilet seat 3 can be washed by discharging water from the inner peripheral edge toward the outer side. In the conventional configuration (the configuration of Japanese Patent Laid-Open No. 2002-54216), the water that cleans the lower surface 3A of the toilet seat 3 has a component toward the opening 7 inside the toilet seat 3, so There was a risk of climbing to the upper surface 3B. In the first embodiment, when the lower surface 3A of the toilet seat 3 is washed, water is discharged from the inner peripheral edge 15 of the toilet seat 3 toward the outside. That is, water is discharged from the inside of the toilet seat 3 to the outside, and as shown in FIG. 1, since there is no water going to the opening 7 inside the toilet seat 3, it is possible to suppress climbing from the opening 7 to the upper surface 3 </ b> B of the toilet seat 3. it can.

  An inclined surface 21 is formed on the lower surface 3A of the toilet seat 3 as shown in FIG. The inclined surface 21 descends obliquely downward from the inside on the opening 7 side of the toilet seat 3 toward the outside. A water discharge port 17 is disposed on the upper end portion 21 </ b> A of the inclined surface 21. The direction of water discharge from the water discharge port 17 is from the inside to the outside, and from the right side to the left side in FIG. In Example 1, the water discharge direction is almost horizontal. Water supplied from the water supply valve device 13 of the toilet seat cleaning device is discharged from the water discharge port 17 toward the inclined surface 21. The discharged water moves downward due to gravity and falls while being guided by the inclined surface 21.

  The lower surface 3 </ b> A of the toilet seat 3 is subjected to water repellent treatment. The method for the water repellent treatment is not particularly limited, and a known method can be appropriately selected. For example, a method of forming a water repellent layer by coating a water repellent is exemplified. When the water repellent treatment is performed, the water spouted on the lower surface 3A is repelled and becomes a substantially spherical shape, which is easy to fall.

  As shown in FIG. 3, the lower end portion 21 </ b> B of the inclined surface 21 of the toilet seat 3 is set lower than the upper surface portion 5 </ b> A of the toilet main body 5. And the lower end part 21B of the inclined surface 21 is located inside the upper surface part 5A of the toilet main body part 5. By setting it as such a positional relationship, it is set as the structure by which the water which falls on the inclined surface 21 by gravity is delivered to the inner surface 5B of the toilet bowl main-body part 5. FIG. Further, the lower end portion 21B of the inclined surface 21 is close to the inner side surface 5B of the toilet main body 5, and water is smoothly transferred from the tip of the lower end 21B to the inner side surface 5B of the toilet main body 5. “Proximity” means 0.5 mm to 30 mm.

<Effect of Example 1>
In the toilet seat device 1 according to the first embodiment, an inclined surface 21 is formed on the lower surface 3A of the toilet seat 3, and the inclined surface 21 descends obliquely downward from the inside to the outside on the opening 7 side of the toilet seat 3. . A water discharge port 17 is disposed on the upper end portion 21 </ b> A of the inclined surface 21, and water is discharged from the water discharge port 17 from the inside to the outside. The discharged water hits the inclined surface 21 and falls along the inclined surface 21 by gravity. Therefore, the toilet seat device 1 according to the first embodiment can efficiently remove water attached to the lower surface 3A of the toilet seat 3 by providing the inclined surface 21 on the lower surface 3A of the toilet seat 3 without using a special member.

  In the toilet seat device 1 according to the first embodiment, a water discharge port 17 is formed on the inner peripheral edge 15 of the lower surface 3 </ b> A of the toilet seat 3 over substantially the entire periphery of the inner peripheral edge 15. The spout 17 is directed from the inside on the opening 7 side of the toilet seat 3 to the outside. Conventionally, water for washing the lower surface 3 </ b> A of the toilet seat 3 is likely to crawl from the opening 7 of the toilet seat 3 to the upper surface 3 </ b> B of the toilet seat 3 because there is a water flow directed toward the opening 7 of the toilet seat 3. In Example 1, when the lower surface 3A of the toilet seat 3 is washed, water is discharged from the inner peripheral edge 15 of the toilet seat 3 toward the outside. That is, water is discharged from the inside of the toilet seat 3 to the outside. Thus, since there is no water which goes to the opening 7 inside the toilet seat 3, it can suppress that water crawls up from the opening 7 of the toilet seat 3 to the upper surface 3B of the toilet seat 3.

  In the toilet seat device 1 according to the first embodiment, the water discharge port 17 is installed on the inner peripheral edge 15 of the toilet seat 3. If the water discharge port 17 is disposed at a position away from the inner peripheral edge 15 and water is discharged from the water discharge port 17 toward the outside, the inner side than the position of the water discharge port 17 cannot be washed. In this case, if the inside of the spout 17 is to be washed, the water will go to the opening 7 inside the toilet seat 3, so that the water can crawl up from the opening 7 of the toilet seat 3 to the upper surface 3 </ b> B of the toilet seat 3. There is sex. In the first embodiment, since water is discharged from the inner peripheral edge 15 to the outside, a wide range of the lower surface 3 </ b> A of the toilet seat 3 can be washed while suppressing water scooping up from the opening 7 of the toilet seat 3.

  In the toilet seat device 1 according to the first embodiment, the lower end portion 21B of the inclined surface 21 of the toilet seat 3 is set lower than the upper surface portion 5A of the toilet body main body 5, and the lower end portion 21B of the inclined surface 21 is the upper surface portion of the toilet body main body 5. It is located inside 5A. When the water falling on the inclined surface 21 due to the action of gravity reaches the lower end 21B of the inclined surface, it is transferred to the inner surface 5B of the toilet body 5. At this time, the lower end 21B of the inclined surface 21 is close to the inner side surface 5B of the toilet main body 5 and water is reliably and smoothly delivered from the tip of the lower end 21B to the inner side 5B of the toilet main body 5. It is.

In the toilet seat device 1 according to the first embodiment, the lower surface 3A of the toilet seat 3 is subjected to water repellent treatment. If the lower surface 3A of the toilet seat 3 is not subjected to water repellent treatment and is hydrophilic, the discharged water spreads on the lower surface 3A of the toilet seat 3 without forming water droplets. In such a state, water tends to hardly fall. In the toilet seat device 1 according to the first embodiment, since the water repellent treatment is performed, the discharged water is easily dropped as water droplets. Therefore, water attached in a short time can be removed.
In addition, in the toilet seat apparatus 1 of Example 1, as shown in FIG. 3, the recessed part 4 dented toward the inner side is formed in the part near the outer edge of the lower side of the toilet seat 3, and the recessed part 4 is a toilet bowl main-body part. 5A, a surface 4A that abuts the upper surface portion 5A, and a surface 4B along the inner side surface 5B of the toilet body 5. The concave portion 4 is at a hidden inner position when viewed from the water discharge port 17 and is a portion that is not easily contaminated.
Moreover, in the toilet seat apparatus 1 of Example 1, as shown in FIG. 3, although the aspect which mounted the toilet seat 3 directly on the toilet bowl main-body part 5 is shown, the leg which consists of rubber | gum etc. is provided in the toilet seat 3, A mode in which the toilet seat 3 is placed on the toilet body 5 can also be adopted. In this case, a portion where the toilet seat 3 is separated from the toilet body 5 is formed. Also in this case, the lower end portion 21B of the inclined surface 21 of the toilet seat 3 is set lower than the upper surface portion 5A of the toilet body main body 5, and the lower end portion 21B of the inclined surface 21 is inside the upper surface portion 5A of the toilet body main body 5. Because it is located in, it is difficult for washing water to fly outside.

<Example 2>
Next, a toilet seat apparatus according to the second embodiment will be described with reference to FIGS. Note that, in the toilet seat device according to the second embodiment, components that are substantially the same as those of the toilet seat device according to the first embodiment are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted. The second embodiment is different from the first embodiment in the following points.

  In the second embodiment, as shown in FIG. 4, a plurality of, specifically, four water outlets 117 are provided in the vicinity of the inner peripheral edge 15 of the toilet seat 3. As shown in FIG. 5, the water discharge direction of each water outlet 117 is an angle of 0 degree or more and less than 90 degrees with respect to the tangent L of the inner peripheral edge at a point on the inner peripheral edge closest to the water outlet 117. Is set to That is, θ in FIG. 5 is an angle of 0 degree or more and less than 90 degrees. In addition, as shown in FIG. 4, each water outlet 117 is installed on the inner periphery 15 at substantially equal intervals. Here, “substantially equidistant” means that the intervals are the same, or even if the intervals are different, the difference is within 50 mm.

  In the case of Example 2, the width of water discharged from each water outlet 117 increases as the distance from the water outlet 117 increases. This is conceptually shown by the width of the arrow shown in FIG. If it does in this way, since the water discharged from the water outlet 117 will spread, the range which can be washed with the water discharged from each water outlet 117 will become wide. However, in this case, the cleaning range of each water discharge port 117 is set so as not to overlap the opening 7 so that the cleaning water does not flow from the opening 7 of the toilet seat 3 to the upper surface 3B of the toilet seat 3. In addition, the aspect which the width of the water discharged from each water outlet 117 does not spread is also employable. That is, this is a mode in which the width of water discharged from each water discharge port 117 does not widen but goes straight.

Here, the effect of Example 2 is demonstrated. Compared to the case where the water discharge direction is 90 degrees with respect to the tangent at the point on the inner peripheral edge closest to the water discharge port 117, the angle is 0 degree or more and less than 90 degrees as in the second embodiment. If set, the path through which water passes the lower surface 3A of the toilet seat 3 can be lengthened. That is, when this angle is set to 90 degrees, the water discharged from the water outlet 117 passes through the lower surface 3A of the toilet seat 3 so as to cross the shortest distance. Therefore, in order to clean the entire surface of the lower surface 3A of the toilet seat 3, it is necessary to form the water outlet 117 over substantially the entire circumference of the inner peripheral edge 15 of the lower surface 3A of the toilet seat 3. On the other hand, if the angle is set to less than 90 degrees, the path through which water passes through the lower surface 3A of the toilet seat 3 can be lengthened. That is, in this case, as shown in FIGS. 4 and 5, the water passes so as to cross the lower surface 3 </ b> A of the toilet seat 3 obliquely. Thus, when the angle is set to less than 90 degrees, the path through which water passes through the lower surface 3A of the toilet seat 3 can be lengthened. Therefore, even if the installation location of the spout 117 is reduced, the lower surface 3A of the toilet seat 3 The entire circumference can be cleaned. Therefore, the toilet seat device 1 according to the second embodiment is advantageous from the viewpoint of cost because the structure can be simplified. Further, the toilet seat device 1 is advantageous from the viewpoint of saving water because it can wash almost the entire lower surface 3A of the toilet seat 3 with a small amount of water. In addition, when the above-mentioned angle is less than 0 degree, it is difficult to splash water on the lower surface 3A of the toilet seat 3 and the cleaning efficiency is lowered, which is not preferable. Further, in this embodiment, the above-described angle is set to 0 degree or more, thereby suppressing the rising of water to the upper surface 3B of the toilet seat 3.
In addition, when each spout 117 is installed on the inner peripheral edge 15 at approximately equal intervals, and the angle of the spout is set to a predetermined angle as described above, the water is swirled as a whole as shown in FIG. Can be shed. In this case, the entire lower surface 3 </ b> A of the toilet seat 3 can be efficiently cleaned with a few spouts 17. Furthermore, in this embodiment, the water flowing from the toilet seat 3 to the toilet main body 5 can also be swirled, which is effective for cleaning the toilet main body 5.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.

(1) In Embodiments 1 and 2, the specific shape of the toilet seat 3 and the specific shape of the toilet body 5 have been described. However, the toilet seats 103, 203, 303, 403, and the toilet body shown in FIGS. 105, 205, 305, and 405 may be used. 7 shows another embodiment (1), FIG. 8 shows another embodiment (2), FIG. 9 shows another embodiment (3), and FIG. 10 shows another embodiment. (4) is shown.
In the toilet seat device of the other embodiments (1), (3), and (4) shown in FIGS. 7, 9, and 10, the inclined surfaces 121 formed on the lower surfaces 103A, 303A, and 403A of the toilet seats 103, 303, and 403, Lower end portions 121B, 321B, and 421B of 321 and 421 are in contact with upper surface portions 105A, 305A, and 405A of toilet main body portions 105, 305, and 405, respectively. As described above, when the lower end portions 121B, 321B, and 421B of the inclined surfaces 121, 321, and 421 are in contact with the upper surface portions 105A, 305A, and 405A of the toilet main body portions 105, 305, and 405, the water is inclined to the inclined surfaces 121 and 321. , 421 can be delivered smoothly to the toilet body 105, 205, 305, 405.

7 and 8, the inclined surfaces 121 and 221 have curved surfaces that are recessed upward. Since these inclined surfaces 121 and 221 are inclined more downward, the water falling on the inclined surfaces 121 and 221 is likely to have a momentum and easily fall. On the other hand, in the case of the other embodiment (4) in FIG. 10, the inclined surface 421 is a curved surface swelled downward, and in this case, the inclination angle becomes smaller as it goes downward. Therefore, the momentum of water becomes smaller as it goes down. In the case of the other embodiment (3) in FIG. 9, the inclined surface 321 has a substantially straight cross section, and in this case, the water descending the inclined surface 321 does not have much momentum. Therefore, in the other embodiments (1) and (2) of FIGS. 7 and 8, water can be removed in a shorter time than in the other embodiments (4) and (3) of FIGS. To preferred.
In the case of the other embodiment (4) in FIG. 10, when water falls on the inclined surface 421, the water may be separated from the inclined surface 421 before reaching the lower end 421 </ b> B of the inclined surface 421. is there. Therefore, water does not flow around the lower end 421B of the inclined surface 421 and the upper end of the toilet body 405, and there is a possibility that this area cannot be washed. That is, cleaning residue may occur. Therefore, also from this viewpoint, the case of the other embodiment (1) in FIG. 7 is preferable to the case of the other embodiment (4) in FIG.
In addition, also when using the toilet seats 103, 203, 303, and 403 like other Example (1)-(4) shown in FIGS. Since water is discharged, it is possible to prevent water from rising from the opening 7 of the toilet seats 103, 203, 303, 403 to the upper surfaces 103B, 203B, 303B, 403B of the toilet seats 103, 203, 303, 403.

  In addition, as shown in another embodiment (1) in FIG. 7, it is preferable that the lower end portion 121B of the inclined surface 121 is continuously connected to the inner side surface 105B of the toilet body main body 105 with almost no step. With this configuration, water can be transferred more smoothly from the inclined surface 121 to the toilet body 105. In general, when a plurality of members are combined, if there is a step in the connection portion, dirt tends to accumulate in the connection portion. In another embodiment (1) of FIG. 7, there is almost no step between the lower end 121B of the inclined surface 121 and the inner surface 105B of the toilet body 105, so that dirt accumulates at this connecting portion. Can be suppressed.

  In another embodiment (2) of FIG. 8, the lower end portion 221B of the inclined surface 221 is disposed on the inner side of the upper surface portion 205A of the toilet body main body 205, so that the washing water jumps out. Can be suppressed.

(2) The toilet seat device may include a dropping device that drops water attached to the lower surface. Using the dropping device can remove the adhering water in a shorter time than when only gravity is used. Here, the dropping device is not particularly limited, and a wide range of devices can be employed. For example, a blower that sends wind toward the lower surface of the toilet seat is exemplified. When this blower is used, a force can be applied to the water droplets by the wind. Then, the component force in the direction of the inclined surface of this force accelerates the speed at which the water droplet slides down the inclined surface, and the adhered water can be removed in a shorter time. The timing for sending wind from the blower is not particularly limited. For example, although the cleaning of the lower surface of the toilet seat and the air blowing may be performed simultaneously, it is not always necessary to perform both at the same time. For example, the structure which blows after wash | cleaning by applying water to the lower surface of a toilet seat can be considered. As described above, the cleaning of the lower surface of the toilet seat and the air blowing may be performed in conjunction with each other. Such interlocking is preferably performed automatically. In addition, although the method of ventilation is not specifically limited, it can ventilate along the lower surface of a toilet seat, and in that case, water can be dropped more efficiently.
An example of the dropping device is a vibrating device that slightly vibrates the toilet seat. When this vibration device is used, water droplets vibrate slightly and slide down the inclined surface more quickly, so that the adhering water can be removed in a short time. The period of vibration is not particularly limited.
Moreover, the timing which vibrates with a vibration apparatus is not specifically limited. For example, although the cleaning of the lower surface of the toilet seat and the vibration may be performed at the same time, it is not always necessary to perform both at the same time. For example, a configuration that vibrates after washing the lower surface of the toilet seat with water is conceivable. As described above, the cleaning of the lower surface of the toilet seat and the vibration may be performed in conjunction with each other. Such interlocking is preferably performed automatically.

  (3) The timing of cleaning the toilet bowl main body and the lower surface of the toilet seat is arbitrary. For example, both may be performed at the same time, but it is not always necessary to perform cleaning at the same time. It is good also as a structure which can perform only washing | cleaning of the lower surface of a toilet seat independently. For example, the structure which provides the special switch for washing | cleaning the lower surface of a toilet seat is illustrated suitably. Further, a function of starting cleaning the lower surface of the toilet seat may be added to an existing switch without using a special switch.

  (4) In Example 1, the spout has a flat slit that is thin in the vertical direction and wide in the width direction. By using the slit of this form, water can be made into a thin film, and a wide range can be efficiently washed. However, in the present invention, the shape of the water outlet is not particularly limited. For example, the water outlet may have various shapes capable of water discharge, such as a cylindrical shape and a rectangular tube shape.

  (5) In Examples 1 and 2 and other Examples (1) to (4), the spout is shown at the upper end of the inclined surface, but the position of the spout is on the inclined surface. The position may deviate from the upper end of. However, the position of the water outlet is preferably near the upper end of the inclined surface. This is because a wide range of the inclined surface can be cleaned by disposing the water outlet near the upper end of the inclined surface.

  (6) In Example 1, the lower surface of the toilet seat is shown as being subjected to water repellent treatment, but the lower surface of the toilet seat may not be subjected to water repellent treatment.

  (7) In Examples 1 and 2, an example having a specific number of water outlets has been shown, but the number of water outlets is appropriately selected according to the shape, size, etc. of the toilet seat.

  (8) The material of the toilet seat and toilet body is not particularly limited, and a known material is appropriately applied.

  (9) In Examples 1 and 2 and the other Examples (1) to (4), the spout is exemplified on the bottom surface of the toilet seat. It may be provided on the lid. For example, as shown in another embodiment (5) in FIG. 11, a spout 217 may be provided at the tip of a rod-like nozzle 216 extending from the toilet body 505 side.

  (10) The washing water discharged is not particularly limited. Water may be discharged as mist, or warm water or sterilized water (such as hypochlorous acid water or silver ion water) may be discharged.
