Description

  The present invention relates to a toilet device provided with a local cleaning device for cleaning a local part of a human body.

  Conventionally, a local cleaning device equipped with a local cleaning nozzle that can be expanded and contracted has been installed on the upper surface of the rear of the flush toilet. A toilet device is known in which local cleaning is performed by extending a local cleaning nozzle and ejecting jet water from the tip of the local cleaning nozzle toward a local part of a human body (see, for example, Patent Document 1).

As another conventional example, for example, as shown in FIG. 8 (b), the lower surface opening 2a of the nozzle insertion / extraction portion 2 of the local cleaning device is projected inward E from the water rim 50 of the bowl portion. It is common to install and extend the local cleaning nozzle 3 from the lower surface opening 2a of the nozzle insertion / removal portion 2.

However, when the lower surface opening 2a of the nozzle loading / unloading portion 2 is installed so as to protrude to the inner side E of the bowl portion 11 as in the prior art, the lower surface opening 2a of the nozzle loading / unloading portion 2 is arranged to face the pool water in the bowl portion 11. For this reason, dirt easily adheres directly to the lower surface opening 2a of the nozzle insertion / removal portion 2 due to the splash water from the accumulated water. Nevertheless, since the lower surface opening 2a of the nozzle insertion / removal portion 2 is a place that is difficult for the user to reach, it is difficult for the user to visually recognize the adhered dirt. Moreover, there are cases where a functional component such as a hot air duct is disposed in the vicinity of the local cleaning nozzle 3, and therefore there are many uneven portions due to the functional components in the nozzle insertion / removal portion 2, and the uneven portions are sufficiently cleaned. This is extremely difficult, and as a result, uncleaned dirt that remains is the cause of toilet odor.
JP 2002-213004 A

  The present invention has been invented in view of the above-described conventional problems, and can prevent sewage from splashing into and out of the nozzle inlet / outlet portion of the local cleaning device that puts in and out the local cleaning nozzle. An object of the present invention is to provide a toilet device in which the cause is eliminated.

  In order to solve the above-mentioned problems, the present invention provides a local cleaning apparatus having an expandable / shrinkable local cleaning nozzle 3 for ejecting jet water toward a local portion of a human body and a nozzle insertion / removal portion 2 for inserting / removing the local cleaning nozzle 3. In the toilet apparatus to which 1 is attached, a rim portion 12 is formed at the upper end portion of the bowl portion 11, and a substantially U-shaped cross section that opens to the rear B of the rim portion 12 inside the rim portion 12 at the rear portion of the bowl portion 11. And the nozzle insertion / removal portion 2 of the local cleaning device 1 is stored in the storage space 13 from the rear B of the rim portion 12 and the inner wall of the rim portion 12 facing the front F of the nozzle insertion / removal portion 2. It is characterized in that a rim opening 14 is formed in 12b so that the local cleaning nozzle 3 can be moved back and forth.

  By adopting such a configuration, there is no possibility that sewage scattered from the outside adheres to the nozzle loading / unloading portion 2 housed in the rim portion 12, and the rim opening portion 14 through which the local cleaning nozzle 3 enters and leaves is the rim portion 12. Since it is formed on the inner wall 12b of the inner wall, the sewage scattered from above and below is less likely to enter from the rim opening 14 of the inner wall 12b, thereby preventing dirt from adhering to the nozzle insertion / removal portion 2, the local cleaning nozzle 3, etc. become able to.

  Further, it is preferable to arrange the front surface portion 1b of the local cleaning device 1 at a position closer to the rear B than the position of the upper extension line A extending upward from the inner wall 12b where the rim opening 14 is formed. The field of view of the inner wall 12b of the rim portion 12 is not hindered by the front surface portion 1b of the local cleaning device 1. That is, the entire inner wall 12b of the rim portion 12 does not become a blind spot, and the user's eyes can easily reach. Therefore, the state of contamination of the entire inner wall 12b of the rim portion 12 can be confirmed at a glance and cleaning is facilitated. .

  In addition, it is preferable that only the front end 3a of the cleaning nozzle 3 is exposed to the rim opening 14 in a state where the local cleaning nozzle 3 is stored in the nozzle insertion / removal portion 2. In this case, the rim opening 14 is temporarily assumed. Even if the sewage enters, the sewage only needs to adhere to the tip 3a of the local cleaning nozzle 3.

  In addition, it is preferable to provide a shutter member 4 for shielding the rim opening 14 in a state where the local cleaning nozzle 3 is stored in the nozzle taking-in / out part 2. In this case, sewage from the rim opening 14 to the nozzle taking-in / out part 2 is provided. Can be reliably prevented by the shutter member 4.

  Further, it is preferable that the shutter member 4 is attached to the tip 3a of the local cleaning nozzle 3, and the shutter member 4 opens and closes the rim opening 14 in accordance with the expansion / contraction of the local cleaning nozzle 3. In this case, the local cleaning is performed. When the nozzle 3 is extended, the shutter member 4 follows the local cleaning nozzle 3 to open the rim opening 14, so that the tip 3a of the local cleaning nozzle 3 protrudes from the rim opening 14 and can be cleaned locally. On the other hand, when the local cleaning nozzle 3 contracts, the shutter member 4 follows the local cleaning nozzle 3 and closes the rim opening 14, so that the nozzle outlet / outlet portion 2 does not receive the splash of sewage and opens and closes the shutter member 4. There is no need to provide a separate driving means.

  In addition, it is preferable that the outer surface of the shutter member 4 is arranged substantially flush with the inner wall 12b of the rim 12 with the shutter member 4 closing the rim opening 14, and in this case, the inner wall of the rim 12 is in this case. When cleaning 12b, the inner wall 12b of the rim portion 12 and the outer surface of the shutter member 4 can be cleaned simultaneously, which not only facilitates the cleaning operation but also efficiently cleans the outer surface of the shutter member 4 to which dirt is most likely to adhere. it can. Moreover, in the state where the shutter member 4 closes the rim opening portion 14, it is possible to obtain a sense of unity in which the inner wall 12 b of the rim portion 12 and the outer surface of the shutter member 4 are continuous, and the appearance is improved.

  According to the present invention, a storage space having a substantially U-shaped cross section opened to the rear of the rim portion is formed inside the rim portion at the rear portion of the bowl portion, and the nozzle insertion / removal portion of the local cleaning device is stored from the rear of the rim portion. In this rim, the sewage can be prevented from splashing into the nozzle loading / unloading section of the local cleaning device, and the local cleaning nozzle can be moved back and forth on the inner wall of the rim facing the front of the nozzle loading / unloading section. By forming the opening, it becomes difficult for sewage scattered from above and below to enter from the rim opening on the inner side wall, and as a result, the cause of the bad odor of the toilet due to the adhesion of dirt can be eliminated.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIGS. 3 and 5, the local cleaning device 1 of this example has a substantially cylindrical nozzle insertion / removal portion 2 protruding from the front surface portion 1 b of the housing 1 a, and extends into the nozzle insertion / removal portion 2. A retractable local cleaning nozzle 3 is stored.

  The local cleaning nozzle 3 includes, for example, a buttocks cleaning nozzle and a bidet cleaning nozzle. As the structure of the local cleaning nozzle 3, for example, a technique known from Japanese Patent Application Laid-Open No. 2002-213004 can be adopted, and detailed description thereof is omitted.

  On the other hand, as shown in FIGS. 1, 2, and 4, the flush toilet 10 is composed of a synthetic resin toilet bowl made of a resin molded product. In this example, the skirt portion 10a, the rim portion 12 and the bowl portion 11 of the flush toilet 10 are separately molded and combined together. FIG. 1 is a perspective view in which the rim portion 12, the bowl portion 11, and the skirt portion 10a are cut away. By the way, the general flush toilet is integrally formed of ceramics by casting, so it is easy to be deformed and cracked at the time of molding, and the product shape cannot be complicated, but the synthetic resin used in the present invention The toilet bowl is excellent in dimensional accuracy, has no advantage of deformation or cracking at the time of molding, and has an advantage that the flush toilet bowl 10 having a complicated shape can be easily formed.

  As shown in FIG. 1, a pair of left and right armrests 15 are disposed on both upper sides of the flush toilet 10, and a support block (not shown) is provided with a support shaft 15a of the armrest 15 at the rear of the flush toilet 10. )). The support block is covered with a side cover 20 (FIGS. 1 and 2).

  The flush toilet 10 includes a bowl portion 11 for storing sealed water, and a discharge port 22 (FIG. 5) at the bottom of the bowl portion 11 is connected to an external pipe via a trap portion not shown. A hollow rim portion 12 is formed at the upper end portion of the bowl portion 11 so as to go around the upper end portion. The interior of the rim portion 12 of the present invention is not a conventional water passage, but a space formed by molding (hereinafter referred to as “storage space 13”), and the nozzle insertion / removal portion of the local cleaning device 1 is placed in the storage space 13. 2 is stored. The interior of the rim portion 12 is made to be a water passage as usual, and a shielded non-water passage space that does not allow water to pass through a part of the rim portion 12 at the rear portion is formed, and the nozzle of the local cleaning device 1 is put in and out of this non-water passage space. The part 2 may be accommodated.

In the following example, a case will be described in which the entire interior of the rim portion 12 is a non-water passage, and the cleaning water passage 6 is formed thereunder. As shown in FIG. 5 (b), in the rim portion 12 of the nozzle out part 2 of the local cleaning device 1 is accommodated, and an upper 12b ₂ of the inner wall 12b and vertical wall, inclined bottom 12b ₁ obliquely backward downward and the inclined wall, thereby opening the rim opening 14 in the bottom 12b _1. In this case, the upper portion 12b ₂ becomes a ridge, and the sewage flowing down from above becomes difficult to enter from the rim opening 14 provided in the lower portion 12b ₁ . Further, the rim opening 14 is opened and closed by the shutter member 4. In the example of FIG. 5, the lower end of the shutter member 4 is pivotally supported vertically on the lower end side of the rim opening 14 and spring means (not shown) that biases the shutter member 4 in the closing direction (upward). ). As a result, the sewage splashing from below is blocked by the shutter member 4 so that it does not enter the rim opening 14.

  Further, as shown in FIG. 2, the rear upper surface 12a of the rim portion 12 is inclined obliquely rearward and upward, and the nozzle inserting / removing portion 2 of the local cleaning device 1 is inclined obliquely forward and downward along this inclination. It is stored in a state. Further, a scattering prevention wall 7 is integrally protruded upward from the upper end on the center side of the rear upper surface 12a of the rim part 12, and the scattering prevention wall 7 allows the front part 1b of the housing 1a of the local cleaning device 1 to be formed. Covered. The height of the scattering prevention wall 7 is set in a range that does not hinder the rotation of the toilet seat 8 and the toilet lid 9.

  Further, the bearing portions 8b on both sides of the lower end of the toilet seat 8 are pivotally supported by shaft portions 30 (FIG. 2) protruding from the front both sides of the housing 1a of the local cleaning device 1. The bearing portions 9a on both lower ends of the toilet lid 9 are pivotally supported by shaft portions 31 (FIG. 2) protruding from both front portions of the housing 1a. Here, when the toilet seat 8 is erected as shown in FIG. 1, the back surface 8a thereof is positioned in front of the scattering prevention wall 7, and the bearing portion 8b of the toilet seat 8 is in front of the front portion 1b of the housing 1a. Thus, for example, urine water scattered and flowing down on the toilet seat 8 flows down to the rear upper surface 12a inclined downward from the front surface of the scattering prevention wall 7 or the bearing portion 8b of the toilet seat 8 and drains into the bowl portion 11. Will come to be. Thus, sewage does not enter the gap 21 (FIG. 21) between the rear upper surface 12a of the rim portion 12 and the lower end of the front surface portion 1b of the local cleaning device 1, and the upper end portion of the scattering prevention wall 7 and the local cleaning device 1 The dirty water does not enter the gap 22 (FIG. 21) with the upper end of the front surface portion 1b. In addition, 60 in FIG. 4 is a recess into which the shaft portion 30 is fitted.

  Further, as shown in FIG. 1, a washing water flow path 6 that circulates in parallel with the rim portion 12 is formed below the rim portion 12 of the bowl portion 11. The washing water channel 6 is formed of a substantially U-shaped groove that is recessed rearward of the inner wall 12b below the inner wall 12b of the rim portion 12 and whose front surface is open. The lower surface of the washing water channel 6 is connected to the inner surface of the bowl portion 11. A short water discharge pipe 5 shown in FIG. 1 is embedded in a part of the washing water flow path 6. The base end of the water discharge pipe 5 is connected to a water supply means (not shown) that receives water from the water pipe, and the front end of the water discharge pipe 5 is a lateral water discharge outlet 5a. In the example of FIG. 1, the spout 5 a opens at a position shifted leftward from the rim opening 14 as viewed from the front of the flush toilet 10 (or may be a position shifted rightward), and the spout 5 a is a rim opening. 14 is open in the opposite direction. Then, the cleaning water from the lateral water discharge port 5a is supplied in the circumferential direction of the cleaning water flow path 6 (the direction indicated by the arrow C in FIG. 1), so that the arrow D in FIG. As shown, swirling flowing water is formed, and the entire inner surface of the bowl portion 11 can be uniformly cleaned with a small amount of cleaning water.

  When the local cleaning nozzle 3 shown in FIG. 5B is extended, the tip 3a of the local cleaning nozzle 3 pushes the shutter member 4 open and protrudes from the rim opening 14 to inject cleaning water to perform local cleaning. Can be done. On the other hand, in the state in which the local cleaning nozzle 3 is stored in the nozzle insertion / removal unit 2 (standby state in FIG. 5A), the shutter member 4 closes the rim opening 14, so that the nozzle insertion / removal unit 2, the local cleaning nozzle 3, etc. It is possible to reliably prevent sewage from splashing.

  Here, since the nozzle loading / unloading portion 2 of the local cleaning device 1 is housed in the housing space 13 inside the rim portion 12 at the rear portion of the bowl portion 11, sewage scattered from the outside adheres to the nozzle loading / unloading portion 2. No fear. Moreover, since the rim opening 14 through which the local cleaning nozzle 3 enters and exits is formed on the inner wall 12b of the rim 12, the sewage scattered from above and below is less likely to enter the rim opening 14 of the inner wall 12b. It is possible to prevent the dirt from adhering to the loading / unloading section 2 and the local cleaning nozzle 3. Further, in this example, since the rim opening 14 is shielded by the shutter member 4 in a state where the local cleaning nozzle 3 is stored in the nozzle insertion / removal portion 2, the scattering of sewage to the nozzle insertion / removal portion 2 is prevented by the shutter member 4. It can be surely prevented. The shutter member 4 can be omitted. Even in this case, if only the tip 3a of the local cleaning nozzle 3 is exposed to the rim opening 14 in a state where the local cleaning nozzle 3 is stored in the nozzle insertion / removal portion 2, Even if the sewage enters from the rim opening 14, the sewage only needs to adhere to the tip 3 a of the local cleaning nozzle 3, and it is possible to prevent the sewage from adhering to the nozzle insertion / removal part 2.

  Also, as described above, by storing the nozzle insertion / removal portion 2 of the local cleaning device 1 in the rim portion 12 of the flush toilet 10, the flush toilet 10 and the local cleaning device 1 can be easily integrated, while the nozzle insertion / removal portion 2 is provided. By pulling out the rim 12 from the inside, the local cleaning nozzle 3 can be easily maintained.

  Further, since the cleaning water is discharged in the horizontal direction from the cleaning water flow path 6 provided below the rim portion 12, swirling water is formed on the inner surface of the bowl portion 11, so that the bowl can be washed with the cleaning water supplied at a low water pressure. There is an advantage that the entire surface of the portion 11 can be reliably cleaned.

  Further, in this example, the front surface portion 1b (FIG. 3) of the local cleaning device 1 is disposed closer to the rear B than the position of the upper extension line (FIG. 5 (a)) extending upward from the inner wall 12b of the rim portion 12. Therefore, the visibility of the inner wall 12b of the rim portion 12 is not hindered by the front surface portion 1b of the local cleaning device 1. That is, the entire inner wall 12b of the rim portion 12 does not become a blind spot, and the user's eyes can easily reach. Therefore, it is possible to confirm the state of dirt attached to the entire inner wall 12b of the rim portion 12 at a glance and to facilitate cleaning.

  FIG. 6 shows another example of the shutter member 4, and the shutter member 4 of this example opens and closes the rim opening 14 by a power source such as a solenoid 40 installed on the bottom surface of the nozzle insertion / removal portion 2. For example, the solenoid 40 is driven by a signal at the time of cleaning the local cleaning nozzle 3, and the rotation link 41 is rotated forward and the vertical rod 42 penetrating the bottom surface of the nozzle insertion / removal portion 2 is pushed down to move the shutter member 4. Opening and local cleaning by the local cleaning nozzle 3 are possible. On the other hand, when the local cleaning nozzle 3 contracts, the rotating link 41 rotates backward and pushes up the vertical rod 42 to close the shutter member 4. Therefore, the nozzle taking-in / out part 2 does not receive scattering of sewage.

  FIG. 7 shows still another example of the shutter member 4. The shutter member 4 of this example is attached to the tip 3 a of the local cleaning nozzle 3, and the shutter member 4 opens to the rim according to the expansion / contraction of the local cleaning nozzle 3. The part 14 is opened and closed. Here, a nozzle hole (not shown) is formed on the top surface of the tip portion 3 a of the local cleaning nozzle 3, and the shutter member 4 is attached to the front surface portion of the tip portion 3 a, so that the nozzle hole is blocked by the shutter member 4. There is no worry about being caught. When the local cleaning nozzle 3 is composed of a buttocks cleaning nozzle and a bidet cleaning nozzle, the shutter member 4 may be attached to the tip of both nozzles. Thus, when the local cleaning nozzle 3 is extended, the shutter member 4 follows the tip 3 a of the local cleaning nozzle 3 to open the rim opening 14, so that the tip 3 a of the local cleaning nozzle 3 protrudes from the rim opening 14. On the other hand, when the local cleaning nozzle 3 contracts, the shutter member 4 moves backward to close the rim opening 14 following the tip 3a of the local cleaning nozzle 3, so that the nozzle can be taken in and out. The part 2 and the local cleaning nozzle 3 are not subjected to the splashing of sewage, and the shutter member 4 opens and closes the rim opening 14 in accordance with the expansion / contraction operation of the local cleaning nozzle 3. There is also an advantage that the configuration of the shutter member 4 can be simplified because it is not necessary to separately provide means.

  5 to 7, it is desirable that the outer surface of the shutter member 4 is substantially flush with the inner wall 12b of the rim portion 12 with the shutter member 4 closing the rim opening 14. . That is, when the shutter member 4 is closed, the outer surface of the shutter member 4 is substantially flush with the inner wall 12b of the rim portion 12, so that when the inner wall 12b of the rim portion 12 is cleaned, The outer surface of the shutter member 4 can be cleaned at the same time, so that not only cleaning work is facilitated, but also the outer surface of the shutter member 4 to which dirt is most likely to adhere can be efficiently cleaned. At this time, since the shutter member 4 is fitted in the rim opening 14 and does not move, the shutter member 4 does not wobble when the outer surface of the shutter member 4 is cleaned, and cleaning is particularly easy as shown in FIG. In the case where the shutter member 4 is integrally attached to the tip 3a of the local cleaning nozzle 3, the cleaning can be performed without imposing a burden on the local cleaning nozzle 3. Moreover, when the shutter member 4 is closed, the inner wall 12b of the rim portion 12 and the outer surface of the shutter member 4 can be obtained in a continuous appearance, so that it is possible to avoid a sense of discomfort in appearance. Both cleanability and appearance can be improved.
