(5) The private parts washing device according to any one of (1) to (4) above, wherein the friction reduction mechanism is arranged in a line along the sliding direction of the second member. In the following description of embodiments 1 to 3, the terms "front-rear direction," "left-right direction," and "up-down direction" refer to the front-rear direction, left-right direction, and up-down direction, respectively, as seen from the perspective of a user using a toilet seat device equipped with a private parts cleansing device in a seated position.

[0009] <Embodiment 1> As shown in FIG. 1, the private parts washing device 1 according to the first embodiment is provided in a toilet seat device 100. The toilet seat device 100 is installed above a toilet bowl 110. The toilet seat device 100 includes a device main body 102, a toilet seat 103, a toilet lid 104, and a remote controller 105. The device main body 102 is disposed at the rear of the toilet bowl 110 and fixed to the toilet bowl 110. The device main body 102 supports the toilet seat 103 and the toilet lid 104 so that they can rotate freely. In addition to the private parts washing device 1, the device main body 102 houses functional components (not shown) such as a warm air drying unit, a toilet seat opening / closing unit, a toilet lid opening / closing unit, and a control unit that controls each unit. The remote controller 105 has an operation unit for operating various functions provided by the functional components in the toilet seat device 100.

[0010] The local cleansing device 1 is housed inside the device main body 102 of the toilet seat device 100. The local cleansing device 1 has a discharge part S that discharges cleansing water. As shown in FIG. 1, when the local cleansing device 1 is to clean the user's local areas, the discharge part S advances from inside to outside the device main body 102. After cleaning is completed, the local cleansing device 1 stores the extended discharge part S inside the device main body 102. In this way, the local cleansing device 1 can freely make the discharge part S extend and retract from inside to outside the device main body 102. The local cleansing device 1 makes the discharge part S extend and retract using a sliding mechanism and an extension mechanism, which will be described later.

[0011] 2 to 4, the local cleansing device 1 includes a guide case 10, a nozzle unit 20, and a roller 30. The guide case 10, the nozzle unit 20, and the roller 30 are examples of the first member, the second member, and the friction reduction mechanism, respectively, according to the present disclosure.

[0012] The guide case 10 is fixed to the device main body 102 of the toilet seat device 100. As shown in FIG. 4, the guide case 10 has a guide portion 11. The guide portion 11, together with a sliding portion 21 (described later) on the nozzle unit 20 side, constitutes the sliding mechanism of the local cleansing device 1. The guide case 10 supports the nozzle unit 20 in this guide portion 11 so that the nozzle unit 20 can slide freely. In this embodiment, a pair of guide portions 11 are provided, one on the left and one on the right. As shown in FIG. 5, each guide portion 11 has a lower wall portion 11A, a side wall portion 11B, and an upper wall portion 11C. The pair of guide portions 11 are formed in a square bracket-shaped cross section with openings facing each other. The guide case 10 is provided with a drive unit (not shown) for moving the nozzle unit 20 relative to the guide case 10 by the sliding mechanism.

[0013] The nozzle unit 20 is configured by integrating multiple nozzles (two in the figure). The nozzle unit 20 as a whole is supported slidably in the guide case 10. In each figure, arrow X indicates the sliding direction of the nozzle unit 20 relative to the guide case 10, with the arrow direction being the forward direction and the opposite direction being the backward direction. The nozzle unit 20 can slide diagonally downward and forward and diagonally upward relative to the guide case 10.

[0014] As shown in Figures 2 to 4, the nozzle unit 20 has a posterior nozzle 40 and a bidet nozzle 50. A discharge section S is provided in each of the posterior nozzle 40 and the bidet nozzle 50. The posterior nozzle 40 and the bidet nozzle 50 are arranged side by side in the left-right direction. The posterior nozzle 40 and the bidet nozzle 50 are each cylindrical with their axial direction as the longitudinal direction. The axial direction of each nozzle 40, 50 is slightly inclined with respect to the sliding direction of the nozzle unit 20, and the front end portions 40A, 50A are arranged close to each other.

[0015] The posterior nozzle 40 and the bidet nozzle 50 each have an extension / retraction mechanism, and extend / retract depending on whether or not cleansing water is supplied. The posterior nozzle 40 and the bidet nozzle 50 extend due to the water pressure of the supplied cleansing water, causing the discharge part S to extend outside the device main body 102. When no cleansing water is supplied and no water pressure is acting inside the posterior nozzle 40 and the bidet nozzle 50, they are contracted by the action of an elastic member (not shown). In this state, the discharge part S is stored inside the device main body 102.

[0016] The posterior nozzle 40 has a nozzle case 41 and a nozzle body 42. The nozzle case 41 and the nozzle body 42 constitute an extension / retraction mechanism. The nozzle case 41 and the nozzle body 42 are each formed in a cylindrical shape with a bottom and an axial direction as the longitudinal direction. The nozzle case 41 has an opening 41A at the front end. The rear end side of the nozzle case 41 is closed. The rear end of the nozzle case 41 is provided with an introduction section 41B that introduces cleansing water into the space inside the nozzle case 41. A water supply hose (not shown) is connected to the introduction section 41B to supply cleansing water.

[0017] As shown in Figures 2 and 3, the nozzle body 42 is closed at its front end and open at its rear end. A water outlet 42A is formed in the upper peripheral surface of the front end of the nozzle body 42, from which cleansing water is discharged. Multiple water outlets 42A (four in Figure 3) are formed. These multiple water outlets 42A constitute the discharge section S of the local cleansing device 1. The nozzle body 42 is housed in the nozzle case 41. The nozzle body 42 is inserted into the nozzle case 41 from the rear end side. The internal space of the nozzle body 42 communicates with the internal space of the nozzle case 41 via the opening on the base end side. The posterior nozzle 40 introduces cleansing water from an introduction section 41B at the rear end of the nozzle case 41, circulating it through the interior of the nozzle case 41 and then the interior of the nozzle body 42, and then discharging it from the water outlet 42A.

[0018] The nozzle body 42 is movable in the axial direction relative to the nozzle case 41, and can freely protrude and retract from the opening 41A of the nozzle case 41. Specifically, the nozzle body 42 moves in the axial direction relative to the nozzle case 41 in accordance with the water pressure of the wash water introduced from the introduction portion 41B of the nozzle case 41. The posterior nozzle 40 expands and contracts due to the relative movement of the nozzle case 41 and the nozzle body 42. The nozzle body 42 protrudes from the nozzle case 41 due to the action of the water pressure of the wash water. When the introduction of wash water is stopped and the internal water pressure decreases, the nozzle body 42 returns to inside the nozzle case 41 due to the action of an elastic member (not shown).

[0019] The bidet nozzle 50 also extends and retracts in the same manner as the posterior nozzle 40. That is, the bidet nozzle 50 has a nozzle case 51, a nozzle main body 52, an opening 51A, an introduction portion 51B, and multiple (four in FIG. 3) water outlets 52A. The nozzle case 51, nozzle main body 52, opening 51A, introduction portion 51B, and multiple water outlets 52A have the same configuration as the nozzle case 41, nozzle main body 42, opening 41A, introduction portion 41B, and multiple water outlets 42A of the posterior nozzle 40, respectively, and function in the same manner.

[0020] As shown in FIGS. 2 and 4, the nozzle unit 20 has a sliding portion 21. As shown in FIG. 4, a pair of sliding portions 21 are provided. The pair of sliding portions 21 are plate-shaped and extend longitudinally in the sliding direction at the bottom of the nozzle cases 41, 51 of the posterior nozzle 40 and the bidet nozzle 50, respectively. Each sliding portion 21 is connected to the nozzle cases 41, 51 via ribs 22. As shown in FIG. 5, the sliding portion 21 is disposed in the guide portion 11 with its lower surface, upper surface, and side surface facing the lower wall portion 11A, upper wall portion 11C, and side wall portion 11B of the guide portion 11. When the nozzle unit 20 slides, the sliding portion 21 is guided by the guide portion 11 on the guide case 10 side. The nozzle unit 20 adjusts the front-rear position of the discharge portion S by sliding the sliding portion 21 along the guide portion 11 on the guide case 10 side.

[0021] The rollers 30 are arranged between the guide case 10 and the nozzle unit 20. The rollers 30 reduce friction when the nozzle unit 20 slides relative to the guide case 10. The rollers 30 are provided so as to be rotatable around an axis perpendicular to the sliding direction of the nozzle unit 20 relative to the guide case 10. A plurality of rollers 30 are provided. The rollers 30 are arranged side by side along the sliding direction of the nozzle unit 20 relative to the guide case 10. Each roller 30 has a shaft portion 31. The shaft portion 31 is formed to have a diameter smaller than the outer diameter of the outer peripheral surface of the roller 30 at both ends in the axial direction of the roller 30.

[0022] In this embodiment, the rollers 30 are attached to the guide case 10. Specifically, as shown in Figs. 6 and 7, the rollers 30 are attached to a base member 32 to form a unit. A pair of base members 32 are provided, and are detachably attached to the lower wall portions 11A of the pair of guide portions 11. Each base member 32 has a roller attachment portion 33. A plurality of roller attachment portions 33 are provided to match the number of rollers 30.

[0023] In this embodiment, three roller mounting portions 33 are provided per base member 32. A roller 30 is individually attached to each roller mounting portion 33. That is, in this embodiment, three rollers 30 are provided per base member 32, for a total of six rollers 30.

[0024] The roller mounting portions 33 are arranged side by side along the longitudinal direction of the rectangular parallelepiped base member 32. Each roller mounting portion 33 is formed by recessing one surface 32A of the base member 32. A bearing portion 33A is provided in each roller mounting portion 33. The bearing portion 33A has a snap-fit structure. The roller 30 is rotatably supported by the bearing portion 33A at the shaft portion 31.

[0025] As shown in Fig. 4, a pair of base members 32 are provided. The pair of base members 32 are attached to mounting grooves 11D formed in the respective lower wall portions 11A of the pair of guide portions 11. As shown in Figs. 5 and 6, the mounting grooves 11D are recessed downward from the upper surface of the lower wall portions 11A, extend along the sliding direction, and open forward at the front ends of the lower wall portions 11A. The base member 32 is attached by being inserted into the mounting groove 11D from the front end opening of the mounting groove 11D along the sliding direction.

[0026] The base member 32 has a restricting portion 34. The restricting portion 34 restricts movement of the base member 32 in the sliding direction. As shown in FIGS. 5 and 7, the restricting portion 34 protrudes from the left and right side surfaces of the base member 32. The restricting portion 34 engages with a restricting groove 11E formed on the left and right side surfaces of the mounting groove 11D. As shown in FIGS. 5 and 6, the restricting groove 11E is formed to extend from the front end of the lower wall portion 11A along the sliding direction and is bent at its rear end in a hook shape in a direction perpendicular to the sliding direction. When the roller unit 60 is mounted in the mounting groove 11D, the restricting portion 34 is inserted from the front end of the restricting groove 11E and engages at its rear end.

[0027] The operation and effect of the private parts washing device 1 configured as described above will now be explained. The private parts washing device 1 starts by operating the operation unit of the remote controller 105 attached to the toilet seat device 100. Specifically, in the private parts washing device 1, cleansing water is supplied from either the introduction portion 41B of the posterior nozzle 40 or the introduction portion 51B of the bidet nozzle 50 in the nozzle unit 20 by operating the operation unit. The posterior nozzle 40 and the bidet nozzle 50 extend due to the water pressure of the supplied cleansing water. The nozzle bodies 42, 52 of the posterior nozzle 40 and the bidet nozzle 50 advance forward from the nozzle cases 41, 51 due to the water pressure of the cleansing water. As a result, the discharge portion S appears outside the device body 102. The private parts washing device 1 continuously supplies washing water to the buttocks nozzle 40 and the bidet nozzle 50 in the extended state, thereby discharging washing water for private parts washing from the water outlets 42A, 52A at the front ends of the nozzle bodies 42, 52.

[0028] The local cleansing device 1 has a nozzle unit 20 provided with a discharge part S that is slidable relative to the guide case 10. This allows the local cleansing device 1 to freely adjust the cleaning position when cleaning the local areas. The cleaning position is adjusted by operating an operating part on the remote controller 105 to drive a drive unit (not shown). This causes the entire nozzle unit 20 to slide relative to the guide case 10. The discharge part S changes its position in accordance with the sliding of the nozzle unit 20, changing the discharge position of the cleansing water back and forth in the sliding direction.

[0029] When the nozzle unit 20 is slid relative to the guide case 10, the sliding portion 21 on the nozzle unit 20 side slides on the guide portion 11 on the guide case 10 side. In the local cleansing device 1, a roller 30 is interposed between the guide portion 11 on the guide case 10 side and the sliding portion 21 on the nozzle unit 20 side. The roller 30 reduces friction with the guide portion 11 when the sliding portion 21 slides. Therefore, scraping noises, creaking noises, etc. are unlikely to occur between the guide portion 11 and the sliding portion 21, realizing quieter operation.

[0030] As described above, the private parts washing device 1 according to the first embodiment is provided in the toilet seat device 100 and has a discharge unit S that discharges washing water for private parts washing. The private parts washing device 1 includes a guide case 10 as a first member according to the present disclosure, a nozzle unit 20 as a second member according to the present disclosure, and a roller 30 as a friction reduction mechanism according to the present disclosure. The guide case 10 is fixedly provided to the device body 102 of the toilet seat device 100. The nozzle unit 20 is provided with a discharge unit S and is supported by the guide case 10 so as to be slidable relative to the guide case 10. The roller 30 is disposed between the guide case 10 and the nozzle unit 20. The roller 30 reduces friction when the nozzle unit 20 slides relative to the guide case 10.

[0031] This configuration can suppress abnormal noises such as scraping and creaking when the nozzle unit 20 slides along the guide case 10 using the rollers 30. As a result, the local cleansing device 1 can be made quieter.

[0032] The local cleansing device 1 employs a roller 30 as a friction reduction mechanism. The roller 30 is rotatable about an axis perpendicular to the sliding direction of the nozzle unit 20. Therefore, the local cleansing device 1 can obtain a good friction reduction effect with a simple configuration.

[0033] A plurality of rollers 30 are arranged side by side along the sliding direction of the nozzle unit 20. Therefore, the local cleansing device 1 can efficiently obtain the effect of reducing friction.

[0034] The roller 30 is attached to the sliding portion 21 on the nozzle unit 20 side. Therefore, the local cleansing device 1 can obtain a good friction reduction effect with a simple configuration.

[0035] <Embodiment 2> The private parts washing device according to the second embodiment differs from the private parts washing device according to the first embodiment in that the friction reduction mechanism is provided on the second member side. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted.

[0036] 8 and 9, the local cleansing device 201 according to the second embodiment includes a guide case 210, a posterior nozzle 240, a bidet nozzle 250, and a roller 230. The guide case 210 is an example of a first member according to the present disclosure. The posterior nozzle 240 and the bidet nozzle 250 are each an example of a second member according to the present disclosure. The roller 230 is an example of a friction reduction mechanism according to the present disclosure.

[0037] Similar to the first embodiment, the local area washing device 201 is housed inside the device main body of the toilet seat device (see FIG. 1). The local area washing device 201 has a discharge part S at the tip of each of the rear nozzle 240 and the bidet nozzle 250. The discharge part S advances from inside to outside the device main body when washing the user's local area, and is stored in the device main body from the advanced state after washing is completed. In this way, the local area washing device 201 can freely extend and retract the discharge part S from inside to outside the device main body 102. Unlike the first embodiment, the local area washing device 201 has only a sliding mechanism to extend and retract the discharge part S.

[0038] In the local cleansing device 201, the posterior nozzle 240 and the bidet nozzle 250 each have an independent, separate structure and can slide independently relative to the guide case 210. In the local cleansing device 201, the posterior nozzle 240 and the bidet nozzle 250 are configured symmetrically. In the local cleansing device 201, the posterior nozzle 240 and the bidet nozzle 250 are arranged symmetrically with respect to the center position in the left-right direction of the guide case 210. The posterior nozzle 240 and the bidet nozzle 250 are configured similarly except for being symmetrical, and slide in a similar manner. In the following explanation, only the configuration related to the posterior nozzle 240 will be explained, and a detailed explanation of the bidet nozzle 250 will be omitted.

[0039] The guide case 210, like the guide case 10 of the first embodiment, is fixedly provided to the device main body of the toilet seat device (see FIG. 1). As shown in FIGS. 8 and 9, the guide case 210 has a guide portion 211 and a drive unit 212. The guide portion 211 is formed in a cylindrical shape with the axial direction as the longitudinal direction. The front end side, which is one end in the axial direction, of the guide portion 211 faces diagonally downward, and the rear end side, which is the other end in the axial direction, faces diagonally upward. A posterior nozzle 240 is inserted into the guide portion 211. The guide case 210 supports the posterior nozzle 240 in this guide portion 211 so that it can slide freely.

[0040] The inner surface of guide portion 211 has a D-shaped cross section with lower surface 211A being flat. Lower surface 211A faces rack gear 243 (described later) of posterior nozzle 240. In local cleansing device 201, the sliding mechanism is made up of lower surface 211A of guide portion 211 and rack gear 243 of posterior nozzle 240. Lower surface 211A is the contact surface with the outer circumferential surface of roller 230 (described later). Notch 211B extending along the axial direction of guide portion 211 is formed on the left side surface of guide portion 211. As shown in FIG. 8, introduction portion 242 (described later) of posterior nozzle 240 passes through notch 211B.

[0041] Drive unit 212 is a drive source for sliding posterior nozzle 240. As shown in FIGS. 8 and 9, drive unit 212 is provided below guide portion 211. Drive unit 212 has gear 212A and motor 212B. Gear 212A is disposed so as to be rotatable about an axis perpendicular to the sliding direction of posterior nozzle 240. A portion of gear 212A is exposed to the inside of guide portion 211 from an opening formed in lower surface 211A of guide portion 211, and meshes with rack gear 243. Motor 212B drives gear 212A to rotate.

[0042] Posterior nozzle 240 is formed in a cylindrical shape with its longitudinal direction in the axial direction. Posterior nozzle 240 is inserted into guide portion 211 along the axial direction. A water outlet 241 that constitutes discharge portion S is formed at the front end of posterior nozzle 240. The rear end of posterior nozzle 240 is closed. Posterior nozzle 240 is provided with introduction portion 242 that introduces cleansing water.Introduction portion 242 protrudes leftward from the outer circumferential surface of posterior nozzle 240. The tip of introduction portion 242 extends rearward parallel to the axial direction of posterior nozzle 240. A water supply hose (not shown) for supplying cleansing water is connected to introduction portion 242.

[0043] As shown in Figure 9, posterior nozzle 240 has a rack gear 243. Rack gear 243 constitutes the sliding mechanism of local cleansing device 201. Rack gear 243 protrudes downward from the underside of posterior nozzle 240, with its teeth facing underside 211A of guide portion 211. Rack gear 243 is provided along the axial direction of posterior nozzle 240. Rack gear 243 meshes with gear 212A of drive unit 212. posterior nozzle 240 slides in the axial direction as the rotational motion of gear 212A is transmitted to rack gear 243 and converted into linear motion.

[0044] Roller 230 is disposed between guide portion 211 and posterior nozzle 240. Roller 230 reduces friction when posterior nozzle 240 slides relative to guide case 210. Roller 230 is provided so as to be rotatable about an axis perpendicular to the sliding direction of posterior nozzle 240 relative to guide case 210.

[0045] In the present embodiment, roller 230 is attached to the posterior nozzle 240 side. Specifically, as shown in Fig. 9, only one roller 230 is attached to the rear of rack gear 243 at the rear of posterior nozzle 240, and is in contact with the lower surface 211A of guide part 211. posterior nozzle 240 is supported by guide case 210 via roller 230. posterior nozzle 240 is supported in front of roller 230 by gear 212A that meshes with rack gear 243. In other words, posterior nozzle 240 is supported at two points: roller 230 and gear 212A.

[0046] The local cleansing device 201 configured as described above, like the local cleansing device 1 according to the first embodiment, can suppress abnormal noises such as scraping and creaking when the rear nozzle 240 and the bidet nozzle 250 slide along the guide case 210 by the rollers 230. Therefore, the local cleansing device 201 can improve quietness.

[0047] The roller 230 serving as the friction reduction mechanism is directly attached to the posterior nozzle 240. Therefore, the local cleansing device 201 can obtain a good friction reduction effect with an even simpler configuration.

[0048] <Embodiment 3> The private parts washing device according to the third embodiment differs from the private parts washing device according to the first embodiment in that a plurality of friction reduction mechanisms are provided on the second member side. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted.

[0049] As shown in Fig. 10, a local cleansing device 301 according to the third embodiment is similar to that of the first embodiment in that it includes multiple rollers 30 as a friction reduction mechanism. In the case of the third embodiment, the rollers 30 are provided on a sliding portion 321 on the nozzle unit 20 side as the second member. The sliding portion 321 has multiple roller attachment portions 333 formed along the sliding direction. Each roller 30 is rotatably supported by the roller attachment portion 333 and is in contact with a lower wall portion 311A of a guide portion 311 in the guide case 10 as the first member.

[0050] In the personal cleansing unit of the third embodiment, when the nozzle unit 20 slides relative to the guide case 10, the rollers 30 provided on the sliding portion 321 roll on the lower wall portion 311A of the guide portion 311, reducing friction. This reduces abnormal noises such as scraping and creaking during sliding, improving quietness.

[0051] The roller 30 serving as the friction reduction mechanism is directly attached to the sliding portion 321 on the nozzle unit side, so a good friction reduction effect can be obtained with an even simpler configuration. That is, compared to the first embodiment, there is no need to provide a base member or a mounting groove for mounting the base member, so a personal cleansing device with an even simpler configuration can be realized.

[0052] <Other embodiments> The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present disclosure.

[0053] (1) The configurations of the first member and the second member are not limited to those exemplified in the above embodiments.

[0054] (2) The configuration of the friction reduction mechanism is not limited to those exemplified in the above embodiments. For example, the friction reduction mechanism may be a spherical rotor that rotates not only around an axis perpendicular to the sliding direction but also in any direction. For example, the friction reduction mechanism may be a member formed into a sheet or plate shape from a resin material with a relatively low friction coefficient, such as polyacetal (POM), polyamide (PA), or polytetrafluoroethylene (PTFE), or a sliding surface formed from a coating layer made of such a material.

[0055] (3) When the friction reduction mechanism is provided on the first member side, it may be provided directly on the first member without going through another member such as the base member described above.

[0056] (4) When the friction reduction mechanism is provided on the second member side, it may not only be provided directly on the second member, but also via another member such as the above-mentioned base member.

[0057] (5) The number of friction reduction mechanisms is not particularly limited. When a plurality of friction reduction mechanisms are provided, the number may be two, or may be three or more. [Explanation of symbols]
