  Hereinafter, a human body local cleaning apparatus 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the width direction means the direction (X direction shown) along the width direction of the cleaning nozzle 10, and the front-back direction means the direction (Y direction shown) along the direction in which the cleaning nozzle 10 moves back and forth. The vertical direction means a direction (Z direction shown) orthogonal to the width direction and the front-rear direction. These directions do not limit the installation direction of the human body local cleaning device 1. For example, the vertical direction may be a direction along the gravity direction, or may be a direction inclined at a constant angle with respect to the gravity direction as in the present embodiment.

[Composition of a human body local cleansing apparatus]
The local human body washing device 1 according to the present embodiment is housed in a housing portion 91 provided at the rear of the toilet seat 90 as shown in FIG. At the time of cleaning, the cleaning nozzle 10 advances (located at the advanced position described later), and the cleaning water is spouted from the spout 112 to clean the local area of the user. The human body local cleaning device 1 shown in FIGS. 2 to 6 includes a cleaning nozzle 10 for cleaning the local area of the human body.

  The cleaning nozzle 10 in the present embodiment is provided so as to be inclined at a predetermined angle with respect to the horizontal direction so that the tip end side is positioned lower than the base end side in the gravity direction. The cleaning nozzle 10 constitutes a nozzle unit 1 u together with the cylinder 20. In other words, the human body local cleaning apparatus 1 according to the present embodiment is an apparatus having a multistage (two-stage) nozzle including the cleaning nozzle 10 and the cylinder 20. The nozzle unit 1 u is supported by the base member 30. A cylinder 20 is slidably supported by the base member 30 in the longitudinal direction, and the cleaning nozzle 10 is slidably supported by the cylinder 20 in the longitudinal direction. It can be said that the cleaning nozzle 10 is supported (indirectly) slidably (advancingly) on the base member 30 via the cylinder 20 (indirectly). The cylinder 20 is a cylindrical member having an opening 24 formed forward, and at least a portion of the cleaning nozzle 10 can enter the cylinder 20. That is, the cylinder 20 can accommodate at least a part of the cleaning nozzle 10.

  In the present embodiment, as the cleaning nozzle 10 (nozzle unit 1 u), an anus cleaning nozzle and a bidet cleaning nozzle are provided side by side in the width direction. The basic difference between the anal cleaning nozzle and the bidet cleaning nozzle is the jet structure of the cleaning water, etc., and there is no difference in the characteristic part of the present invention, so the two cleaning nozzles (nozzle unit 1u) are distinguished. The human body local cleaning device 1 according to the present embodiment will be described simply as "cleaning nozzle 10 (nozzle unit 1u)" without having to do it.

  The cleaning nozzle 10 is an elongated shaft-like member, and has a main body portion 11 (corresponding to a proximal end portion in the present invention) and a head portion 12 (corresponding to a distal end portion in the present invention). The main body portion 11 is a portion that constitutes the rear side of the cleaning nozzle 10, and a space through which the hose 40 passes is formed inside. The head portion 12 is a portion provided on the front side (tip end side) of the main body portion 11, and a fluid space 121 into which washing water flows is formed in its inside. A jet 122 communicating with the fluid space 121 is formed on the upper side of the head 12. One end of a hose 40 is connected to the cleaning nozzle 10 so as to be in fluid communication with the fluid space 121, and the cleaning water conveyed by the hose 40 and flowing into the fluid space 121 is above the spout 122 (local area of the human body). It is spouted towards. The structure of the spout 122 such as the shape may be any shape, so the detailed description will be omitted.

  The cleaning nozzle 10 in the present embodiment is formed so that the head portion 12 is thicker (the cross-sectional area is larger) than the main body portion 11. That is, at the boundary between the head portion 12 and the main body portion 11, a step of the difference in thickness is generated. The main body portion 11 has a thickness that can enter the inside of the cylinder 20 (which can slide inside) described in detail later, while the head portion 12 has a thickness that can not enter the inside of the cylinder 20. . Specifically, the size of the outer peripheral edge of the head portion 12 is larger than the edge of the opening 24 of the cylinder 20. In the present embodiment, the head portion 12 functions as the covering portion 10c.

  A hose 40, one end of which is connected to the washing nozzle 10 so as to be in fluid communication with the fluid space 121, is made of a deformable material (eg, rubber) and is drawn from the rear of the washing nozzle 10. The hose 40 may be connected to the washing nozzle 10 so that the washing water to be conveyed is jetted from the jet port 122, and the connection position and the connection structure with respect to the washing nozzle 10 are whatever. Good. The hose 40 in the present embodiment is pulled backward through a space formed inside the main body 11 of the cleaning nozzle 10.

  Behind the main body 11 of the cleaning nozzle 10, a rack connection 13 is provided. One end of a flexible rack 50 is connected to the rack connection portion 13. As will be described later, the power of the motor 32 serving as the driving source is transmitted to the cleaning nozzle 10 through the flexible rack 50.

  The cylinder 20 is a cylindrical member in which the main body 11 of the cleaning nozzle 10 can be inserted, but the head 12 positioned on the front side of the main body 11 can not enter. The cleaning nozzle 10 can be displaced relative to the cylinder 20. That is, the cleaning nozzle 10 can slide relative to the cylinder 20 so as to change the size of the main body 11 that enters the cylinder 20. Specifically, an opening 24 is formed at the front end of the cylinder 20, and the main body 11 of the cleaning nozzle 10 can pass inside the opening 24, and the cleaning nozzle 10 is a cylinder 20 through the opening 24. It is possible to slide in and out. As described above, since the cleaning nozzle 10 (the main body 11) is slidable with respect to the cylinder 20, a small gap is present between the main body 11 of the cleaning nozzle 10 and the edge of the opening 24. Although the cylinder 20 in the present embodiment is a cylindrical member, it may have a shape in which a part of the peripheral wall is open.

  A hook 21 is formed at the edge of the opening 24 of the cylinder 20, and when the relative position of the cleaning nozzle 10 with respect to the cylinder 20 is the foremost, the hook 21 and the rack connection 13 are in contact with each other. . That is, the rack connection portion 13 can not pass through the opening 24. As a result, the cleaning nozzle 10 can not move further forward with respect to the cylinder 20. That is, the rack connection portion 13 functions not only as a portion to which the flexible rack 50 is connected, but also as a retention stopper for the cleaning nozzle 10 from the cylinder 20. In addition, since the head portion 12 of the cleaning nozzle 10 is formed in a size that can not pass through the opening 24, the rear end face of the head portion 12 when the relative position of the cleaning nozzle 10 to the cylinder 20 becomes the rearmost. Contacts the tip surface of the cylinder 20. At this time, a small gap is covered by the head 12 between the main body 11 of the cleaning nozzle 10 described above and the edge of the opening 24.

  In the rear of the cylinder 20, a hose insertion hole 22 through which the hose 40 is passed and a rack insertion hole 23 through which the flexible rack 50 is passed are formed.

  The cylinder 20 is slidably supported on the base member 30 in the axial direction (front-rear direction). Specifically, the cylinder 20 is slidable between an original position located at the rearmost position and an advanced position located at the frontmost position inside the cylindrical housing portion 35 formed on the front side of the base member 30. It is supported to be Although detailed description is omitted, the base member 30 has a stopper portion for preventing the cylinder 20 from moving forward of the advanced position and for preventing movement behind the original position.

  The other end of the hose 40, one end of which is connected to the washing nozzle 10, that is, the end near the water source, is directly or indirectly connected to the base member 30. In the present embodiment, the other end of the hose 40 is connected to the water supply port 31 fixed to the base member 30. Cleaning water flows from the water source into the hose 40 through the water supply port 31. A valve (not shown) or the like is provided on the upstream side of the water supply port 31 in order to control whether the water supply to the cleaning nozzle 10 is possible (whether or not the cleaning water is spouted from the spout 122). The valve provided with the water supply port 31 of this type may be fixed to the base member 30, and the other end of the hose 40 may be connected to the water supply port 31.

  A motor 32 which is a drive source for driving the cleaning nozzle 10 (nozzle unit 1 u) is fixed to the base member 30. An output gear 321 is fixed to the drive shaft of the motor 32. One end of the output gear 321 is connected to the cleaning nozzle 10 (the rack connection portion 13), and the output gear 321 meshes with the flexible rack 50 in a state of being pulled out to the base member 30 through the rack insertion hole 23 of the cylinder 20. Therefore, when the motor 32 is driven, its power is transmitted to the cleaning nozzle 10 via the output gear 321 and the flexible rack 50.

  Further, a rack restricting portion 33 and a rack guiding portion 34 are provided on the base member 30. The rack restricting portion 33 is an arc-shaped portion in which a part of the flexible rack 50 moved rearward is curved in an arc shape. That is, it is a portion for restricting the shape of the flexible rack 50. By setting the flexible rack 50 in a curved state as described above, the drive mechanism for driving the cleaning nozzle 10 can be made compact. The rack restricting portion 33 in the present embodiment has an arc shape (an arc shape which is convex toward the rear) which is directed downward from above the base member 30. More specifically, the rack restricting portion 33 has an outer circular arc-shaped projection 331 and an inner circular arc-shaped projection 332 provided so as to be along each other at a predetermined interval, and a flexible rack is provided in the groove between both the projections. 50 will fit in.

  As described above, one end of the hose 40 is connected to the cleaning nozzle 10, and the other end is connected to the base member 30 via the water supply port 31. In a rough view, the hose 40 is connected to the cleaning nozzle 10 at one end along a plane (YZ plane) orthogonal to the width direction, straightly pulled from the rear of the cleaning nozzle 10, and makes a U-turn at the rear As described above, the other end, which is the end of the portion directed forward, is curved so as to be downwardly bent, and is drawn around so as to be connected to the water supply port 31 located along the longitudinal direction. That is, the hose 40 is in a state where a part between one end and the other end is curved. The curved portion is located inside the rack restricting portion 33. As described in detail later, when the cleaning nozzle 10 moves back and forth, the position of one end of the hose 40 connected to the cleaning nozzle 10 changes, so the curvature of the hose 40 changes. When the cleaning nozzle 10 is at the original position (details will be described later), the radius of curvature of the curved portion of the hose 40 is the largest. However, since the rack regulating portion 33 (inner circular arc-shaped projection 332) is provided on the outside of the curved portion of the hose 40, the radius of curvature of the curved portion of the hose 40 is equal to or greater than the radius of curvature of the rack regulating portion 33. It will never be. That is, the rack restricting portion 33 (the inner arc-shaped projection 332) not only restricts the shape of the flexible rack 50, but also restricts the shape of the curved portion of the hose 40.

  The rack guiding portion 34 is a portion for guiding the flexible rack 50 toward the rack restricting portion 33. The rack guiding portion 34 in the present embodiment linearly extends forward from one end (upper end) of the rack restricting portion 33. More specifically, the rack guiding portion 34 has an outer linear protrusion 341 and an inner linear protrusion 342 provided along a predetermined distance apart from each other, and a flexible rack is provided in a groove between the two protrusions. 50 will fit in. In the present embodiment, the groove formed by the rack guiding portion 34 is connected to the groove formed by the rack restricting portion 33. The rack guiding portion 34 and the rack restricting portion 33 may not be connected but may be separated. The rack guiding portion 34 is located below the portion of the flexible rack 50 that meshes with the output gear 321. That is, the rack guiding portion 34 is a portion provided to support a portion of the flexible rack 50 meshing with the output gear 321 from the lower side and to maintain the state in which the output gear 321 and the flexible rack 50 are meshed.

  A nozzle cleaning device 60 for keeping the cleaning nozzle 10 clean is provided in front of the accommodation portion 35 of the base member 30. The nozzle cleaning device 60 is provided above the head portion 12 (jet port 122) of the cleaning nozzle 10 located at the original position. The cleaning device cleans the head portion 12 (jet port 122) by spouting water (nozzle cleaning water) toward the head portion 12 of the cleaning nozzle 10.

[Operation of human body local cleansing system]
The human body local cleaning device 1 having such a configuration operates as follows. When the cleaning nozzle 10 is positioned at the rearmost position at the original position (see FIG. 3), when the motor 32 as the drive source is rotated in one direction (normally rotated), the power is output gear 321 and flexible rack 50 And the cleaning nozzle 10 is advanced. Since the power of the drive source is not directly transmitted to the cylinder 20, the cleaning nozzle 10 advances so that the portion of the cleaning nozzle 10 contained in the cylinder 20 is gradually exposed. However, due to the frictional force generated between the cleaning nozzle 10 and the cylinder 20, the cylinder 20 may be first advanced together with the cleaning nozzle 10 (see FIG. 4). The flexible rack 50, which has been in a curved state by the rack restricting portion 33, linearly changes by the rack guiding portion 34 and is displaced forward together with the cleaning nozzle 10.

  When the cleaning nozzle 10 advances to a predetermined position, the rack connection portion 13 of the cleaning nozzle 10 is hooked on the hooking portion 21 of the cylinder 20, whereby the cylinder 20 also advances with the cleaning nozzle 10. Finally, the cleaning nozzle 10 is advanced to a position where the cylinder 20 is restricted by the base member 30 in its advancement, and reaches the advanced position (see FIG. 5). When the cleaning nozzle 10 advances in this manner, one end of the hose 40 connected thereto is also displaced forward, so the radius of curvature of the curved portion of the hose 40 gradually decreases and becomes the smallest at the advanced position.

  With the cleaning nozzle 10 positioned at the advanced position, cleaning water is supplied to the cleaning nozzle 10 through the hose 40, and the cleaning water is spouted from the spout 122. A plurality of positions may be set as the advanced position (cleaning position).

  When the cleaning nozzle 10 located at the advanced position is returned to the original position, the motor 32, which is a driving source, is rotated to the other side (reversed). Thereby, the cleaning nozzle 10 is retracted. The flexible rack 50 enters into the rack regulation unit 33 while being guided by the rack guiding unit 34. That is, the portion curved by the rack restricting portion 33 gradually increases. When the cleaning nozzle 10 contacts the rear end surface of the cylinder 20, the cylinder 20 is retracted together with the cleaning nozzle 10, and both are returned to the original position. The frictional force generated between the cleaning nozzle 10 and the cylinder 20 may initially retract the cylinder 20 together with the cleaning nozzle 10. When the cleaning nozzle 10 retracts, one end of the hose 40 connected thereto is also displaced rearward, so the radius of curvature of the curved portion of the hose 40 gradually increases and becomes the largest at the original position.

  Thus, the cleaning nozzle 10 moves back and forth. In addition, if the cleaning nozzle 10 has a structure capable of advancing and retracting between the original position and the advanced position (cleaning position), the drive mechanism of the cleaning nozzle 10 can be appropriately changed.

  In the present embodiment, the cleaning nozzle 10 and the cylinder 20 positioned at the original position are positioned so as to overlap with the accommodation portion 35 of the base member 30. Specifically, a portion of the cleaning nozzle 10 excluding a part of the head portion 12 and the cylinder 20 are located inside the housing portion 35.

  When the cleaning nozzle 10 is in the original position, the cleaning device ejects cleaning water toward the head portion 12 (jet port 122) of the cleaning nozzle 10. In addition, the timing which performs the said nozzle washing | cleaning may be what kind of thing. After local cleaning, the cleaning may be performed each time the cleaning nozzle 10 returns to the original position, or when the number of local cleanings exceeds a predetermined number or when a predetermined time has elapsed since the previous cleaning. You may do it. The user may be able to perform the nozzle cleaning at any timing.

[Function of covering section]
The function (effect) of the covering portion 10c provided on the cleaning nozzle 10 of the human body partial body cleaning apparatus 1 operating as described above will be described. Since the size (the size of the outer periphery) of the head portion 12 of the cleaning nozzle 10 is one size larger than the size of the edge of the opening 24 formed in the cylinder 20, the head portion 12 enters the inside of the cylinder 20 through the opening 24. There is no. Therefore, when the cleaning nozzle 10 is located at the original position, the rear end surface of the head portion 12 is in close contact with the front end surface of the cylinder 20. That is, the gap between the outer surface of the cleaning nozzle 10 and the edge of the opening 24 is covered by the head portion 12. As described above, since the head portion 12 functions as the covering portion 10 c and covers the gap, the penetration of water or the like into the inside of the apparatus (the inside of the base member 30) from the gap is suppressed. In order to enhance the adhesion of the rear end surface of the head portion 12 to the front end surface of the cylinder 20, an elastic body such as rubber may be provided on at least one of the surfaces.

  In particular, the human body local cleaning apparatus 1 according to the present embodiment includes the nozzle cleaning apparatus 60 that cleans the cleaning nozzle 10 when the cleaning nozzle 10 is located at the original position. Even when the cleaning nozzle 10 is cleaned by the nozzle cleaning device 60, water for cleaning the nozzle can be suppressed from entering the inside of the device through the gap.

[Modification etc. of the above embodiment]
As mentioned above, although embodiment of this invention was described in detail, this invention is not limited at all to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention. For example, the following modifications can be made.

  In the human body local cleaning device 1 in the above embodiment, the head portion 12 of the cleaning nozzle 10 formed to be thicker than the main body portion 11 is a covering portion 10 c covering a gap between the outer surface of the cleaning nozzle 10 and the edge of the opening 24. Although the function has been described, the cleaning nozzle 10 may be configured as shown in FIG. The cleaning nozzle 10 shown in FIG. 7 has a boundary portion 14 thicker than the main body portion 11 between the head portion 12 (tip end side portion) and the main body portion 11 (proximal end portion). That is, by providing a bowl-shaped border 14 whose outer edge has a size slightly larger than the edge of the opening 24, when the cleaning nozzle 10 is at the original position, the gap is covered by the border 14. Therefore, it is suppressed that water etc. enter into the inside of an apparatus from the said clearance gap. The boundary portion 14 in the present example is thicker than the head portion 12.

  The cleaning nozzle 10 in this example is superior to the cleaning nozzle 10 in the above embodiment in that the amount of the material forming the cleaning nozzle 10 can be reduced. On the other hand, the cleaning nozzle 10 in the above embodiment has a shape with few corners and the like, and is superior to the cleaning nozzle 10 in this example in terms of easy cleaning of the cleaning nozzle 10 (head portion 12).

  Further, in the human body local cleaning device 1 in the above embodiment and the example shown in FIG. 7, the covering portion 10 c (the head portion 12 and the boundary portion 14) of the cleaning nozzle 10 located in the original position Although it has been described that the gap between the opening 20 and the edge of the opening 24 is covered, not only the gap (first gap) but also the outer surface of the cylinder 20 and the base member 30 (the housing portion 35) are described. It may be configured to cover a gap (second gap) between the opening 36 and the edge of the opening 36.

  As described above, the cylinder 20 is provided so as to be slidable inside the cylindrical housing portion 35 formed on the front side of the base member 30. Therefore, a minute gap (second gap) is present between the outer surface of the cylinder 20 and the edge of the opening 36 formed in the base member 30 (the housing portion 35). As shown in FIG. 8, the size of the outer edge of the covering portion 10 c (head portion 12, boundary portion 14) constructed on the cleaning nozzle 10 is made larger by one turn than the outer edge of the front end face of the cylinder 20. When the nozzle 10 is positioned at the original position, the second gap is covered with the covering portion 10c together with the first gap. Therefore, it is suppressed that water etc. enter into the inside of an apparatus from a 1st clearance gap or a 2nd clearance gap. In addition, although the accommodating part 35 in this embodiment has a shape which the width direction both sides opened, it is good also as a shape which covers all around the cylinder 20. FIG.

  Further, the human body local cleaning device 1 in the above embodiment and the examples shown in FIG. 7 and FIG. 8 are provided with multi-stage nozzles (two-stage nozzle unit 1 u having the cleaning nozzle 10 and the cylinder 20). Although it has been described that the opening 24 for coming and going is formed in the cylinder 20, it is not limited thereto. The same technical concept can be applied to a structure in which one cleaning nozzle 10 simply moves back and forth with respect to the base member 30. That is, in the case where the opening for inserting and retracting the cleaning nozzle 10 is formed in the base member 30, when the cleaning nozzle 10 is at the original position, the covering portion 10c (head portion 12, boundary portion 14) is cleaned. The gap between the outer surface of the nozzle 10 and the edge of the opening formed in the base member 30 (the housing portion 35) may be covered.

  Further, in the human body local cleaning apparatus 1 according to the above-described embodiment and the examples shown in FIGS. 7 and 8, the covering portion 10 c (the head portion 12 and the boundary portion 14) provided on the cleaning nozzle 10 is outside the opening 24 or Although the structure in which the gap is covered is described, the covering portion 10 c may cover the gap from the inside of the opening 24 or the opening 36. For example, the cover 10 c may be provided on the portion of the cleaning nozzle 10 located inside the cylinder 20, and the cover 10 c may cover the opening 24 from the inside of the cylinder 20. In addition, a covering portion 10 c may be provided on a portion of the cylinder 20 located inside the accommodation portion 35, and the covering portion 10 c may cover the opening 36 from the inside of the accommodation portion 35.
