JP 59-170338 A

  In the conventional local body cleaning device, various liquids and dusts enter the device through the gap between the cleaning nozzle and the edge of the opening through which the cleaning nozzle passes (hereinafter, such a device should not enter the device). (There are cases where there is no such thing as water). In particular, when a device for cleaning the cleaning nozzle itself as described in Patent Document 1 is provided, when nozzle cleaning water is ejected toward the cleaning nozzle, the nozzle cleaning water enters the inside of the device through the gap. Therefore, the problem becomes remarkable.

  The problem to be solved by the present invention is to provide a human body local cleaning device capable of suppressing water and the like from entering through a gap between the cleaning nozzle and the edge of the opening through which the cleaning nozzle passes.

  Hereinafter, a human body local cleaning device 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 a direction along the width direction of the cleaning nozzle 10 (X direction shown in the figure), and the front-rear direction means a direction along the direction in which the cleaning nozzle 10 moves back and forth (Y direction shown in the figure). In other words, the vertical direction means the direction (Z direction shown in the figure) 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 by a certain angle with respect to the gravity direction as in the present embodiment.

[Configuration of local body cleaning equipment]
The human body local cleaning device 1 according to the present embodiment is accommodated in an accommodating portion 91 provided behind the toilet seat 90 as shown in FIG. At the time of washing, the washing nozzle 10 moves forward (positioned at an advanced position described later), and washing water is ejected from the ejection port 112 to wash the user's local area. 2 to 6 includes a cleaning nozzle 10 for cleaning a local part of a 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, and the distal end side is located below the proximal end side in the gravity direction. The cleaning nozzle 10 and the cylinder 20 constitute a nozzle unit 1u. In other words, the human body local cleaning device 1 according to the present embodiment is a device having a multi-stage (two-stage) nozzle composed of the cleaning nozzle 10 and the cylinder 20. The nozzle unit 1u is supported by the base member 30. A cylinder 20 is supported on the base member 30 so as to be slidable in the longitudinal direction, and the cleaning nozzle 10 is supported on the cylinder 20 so as to be slidable in the longitudinal direction. It can be said that the cleaning nozzle 10 is supported by the base member 30 through the cylinder 20 (indirectly) so as to be slidable (possible to advance and retract). The cylinder 20 is a cylindrical member having an opening 24 formed in the front, and at least a part 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 this embodiment, as the cleaning nozzle 10 (nozzle unit 1u), 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 structure of the washing water jetting, etc., and there is no difference in the characteristic part of the present application, so the two cleaning nozzles (nozzle unit 1u) are distinguished. The human body local cleaning apparatus 1 according to the present embodiment will be described simply as “cleaning nozzle 10 (nozzle unit 1 u)” without any reference.

  The cleaning nozzle 10 is an elongated shaft-like member, and has a main body portion 11 (corresponding to a base end side portion in the present invention) and a head portion 12 (corresponding to a distal end side portion in the present invention). The main body 11 is a part constituting the rear side of the cleaning nozzle 10, and a space through which the hose 40 is passed is formed inside. The head portion 12 is a portion provided on the front side (front end side) of the main body portion 11, and a fluid space 121 into which cleaning water flows is formed in the head portion 12. A jet port 122 connected to the fluid space 121 is formed on the upper side of the head portion 12. One end of a hose 40 is connected to the cleaning nozzle 10 so as to communicate with the fluid space 121, and the cleaning water transported by the hose 40 and flowing into the fluid space 121 is located above the jet nozzle 122 (local part of the human body). It is ejected toward. Since the shape or the like of the structure of the ejection port 122 may be any, detailed description is omitted.

  The cleaning nozzle 10 in this 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, there is a difference in the thickness difference at the boundary between the head portion 12 and the main body portion 11. The main body 11 has a thickness that can enter the inside of the cylinder 20, which will be described in detail later (can slide inside), while the head 12 has a thickness that cannot 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.

  The hose 40 having one end connected to the cleaning nozzle 10 so as to communicate with the fluid space 121 is formed of a deformable material (for example, rubber), and is pulled out from the rear of the cleaning nozzle 10. The hose 40 may be connected to the cleaning nozzle 10 so that the cleaning water to be transported is ejected from the ejection port 122, and any connection position or connection structure with respect to the cleaning nozzle 10 may be used. Good. The hose 40 in the present embodiment is drawn backward through a space formed inside the main body 11 of the cleaning nozzle 10.

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

  The cylinder 20 is a cylindrical member in which the main body portion 11 of the cleaning nozzle 10 can enter, but the head portion 12 positioned in front of the main body portion 11 cannot enter. The cleaning nozzle 10 can be displaced relative to the cylinder 20. That is, the cleaning nozzle 10 can slide with respect to the cylinder 20 so as to change the size of the main body portion 11 entering the cylinder 20. Specifically, an opening 24 is formed at the front end of the cylinder 20, and the main body portion 11 of the cleaning nozzle 10 can pass inside the opening 24, and the cleaning nozzle 10 is inserted into the cylinder 20 through the opening 24. It is possible to slide in and out from. As described above, since the cleaning nozzle 10 (main body portion 11) is slidable with respect to the cylinder 20, there is a small gap between the main body portion 11 of the cleaning nozzle 10 and the edge of the opening 24. In addition, although the cylinder 20 in this embodiment is a cylindrical member, the shape which a part of peripheral wall opened may be sufficient.

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

  A hose insertion hole 22 through which the hose 40 passes and a rack insertion hole 23 through which the flexible rack 50 passes are formed at the rear of the cylinder 20.

  The cylinder 20 is supported slidably along the axial direction (front-rear direction) with respect to the base member 30. 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 become. Although detailed description is omitted, the base member 30 has a stopper portion for preventing the cylinder 20 from moving forward from the advanced position and from moving backward from the original position.

  The other end of the hose 40 whose one end is connected to the cleaning 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 a water supply port 31 fixed to the base member 30. Wash water flows from the water source into the hose 40 through the water supply port 31. A valve (not shown) is provided on the upstream side of the water supply port 31 in order to control whether or not water can be supplied to the cleaning nozzle 10 (whether or not the cleaning water is jetted from the jet nozzle 122). A structure in which a valve provided with this type of water supply port 31 is fixed to the base member 30 and the other end of the hose 40 is connected to the water supply port 31 may be employed.

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

  Further, the base member 30 is provided with a rack restricting portion 33 and a rack guiding portion 34. The rack restricting portion 33 is an arc-shaped portion that causes a part of the flexible rack 50 moved rearward to be curved in an arc shape. That is, it is a part for regulating the shape of the flexible rack 50. By setting the flexible rack 50 to be curved in this way, 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 that protrudes rearward) that extends downward from above the base member 30. More specifically, the rack restricting portion 33 has an outer arc-shaped protrusion 331 and an inner arc-shaped protrusion 332 that are provided along a predetermined distance from each other, and a flexible rack is formed in a groove between the two protrusions. 50 will be fitted.

  As described above, the hose 40 has one end connected to the cleaning nozzle 10 and the other end connected to the base member 30 via the water supply port 31. When viewed roughly, the hose 40 is connected to the cleaning nozzle 10 at one end so as to be along a plane orthogonal to the width direction (YZ plane), and is directly pulled out from the rear of the cleaning nozzle 10 and makes a U-turn at the rear. The other end, which is the end of the portion that curves forward and curves forward, is connected to the water supply port 31 that is positioned along the front-rear 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 will be 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 located at the original position (details will be described later), the radius of curvature of the curved portion of the hose 40 becomes the largest. However, since the rack restricting portion 33 (inner arcuate protrusion 332) is provided outside the curved portion of the hose 40, the radius of curvature of the curved portion of the hose 40 is greater than or equal to the radius of curvature of the rack restricting portion 33. It will never be. That is, the rack restricting portion 33 (inner arcuate protrusion 332) not only plays a role of restricting the shape of the flexible rack 50, but also plays a role of restricting the shape of the curved portion of the hose 40.

  The rack guiding part 34 is a part for guiding the flexible rack 50 toward the rack restricting part 33. The rack guide portion 34 in the present embodiment extends linearly from one end (upper end portion) of the rack restricting portion 33 toward the front. More specifically, the rack guide portion 34 has an outer straight protrusion 341 and an inner straight protrusion 342 provided along a predetermined distance from each other, and a flexible rack is formed in a groove between the protrusions. 50 will be fitted. In the present embodiment, the groove constituted by the rack guiding portion 34 is connected to the groove constituted by the rack restricting portion 33. The rack guiding part 34 and the rack restricting part 33 are not connected and may be separated. Further, the rack guide 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 also a portion provided to support a portion of the flexible rack 50 that meshes with the output gear 321 from the lower side and maintain the state where 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 housing portion 35 of the base member 30. The nozzle cleaning device 60 is provided so as to be positioned above the head portion 12 (jet port 122) of the cleaning nozzle 10 positioned at the original position. The cleaning device cleans the head portion 12 (spout port 122) by ejecting water (nozzle cleaning water) toward the head portion 12 of the cleaning nozzle 10.

[Operation of local body cleaning equipment]
The human body local cleaning device 1 having such a configuration operates as follows. When the cleaning nozzle 10 is in the original position, which is the rearmost position (see FIG. 3), when the motor 32 that is the driving source is rotated in one direction (forward rotation), the power is output to the output gear 321 and the flexible rack 50. Is transmitted to the cleaning nozzle 10 via the nozzle, and the cleaning nozzle 10 advances. Since the power of the drive source is not directly transmitted to the cylinder 20, the cleaning nozzle 10 moves forward so that the portion of the cleaning nozzle 10 housed in the cylinder 20 is gradually exposed. However, a configuration in which the cylinder 20 first moves forward together with the cleaning nozzle 10 by a frictional force generated between the cleaning nozzle 10 and the cylinder 20 (see FIG. 4) may be used. The flexible rack 50 that has been bent by the rack restricting portion 33 changes to a linear shape by the rack guiding portion 34 and is displaced forward together with the cleaning nozzle 10.

  When the cleaning nozzle 10 moves forward to a predetermined position, the rack connecting portion 13 of the cleaning nozzle 10 is hooked on the catching portion 21 of the cylinder 20, so that the cylinder 20 moves forward together with the cleaning nozzle 10. Eventually, the cleaning nozzle 10 advances to a position where the forward movement of the cylinder 20 is restricted by the base member 30, and reaches the advanced position (see FIG. 5). When the cleaning nozzle 10 moves forward in this way, one end of the hose 40 connected thereto is also displaced forward, so that the radius of curvature of the curved portion of the hose 40 gradually decreases and becomes the smallest at the advanced position.

  In the state where the cleaning nozzle 10 is located at the advanced position, the cleaning water is supplied to the cleaning nozzle 10 through the hose 40, and the cleaning water is ejected from the ejection port 122. A plurality of positions may be set as the advance position (cleaning position).

  When returning the cleaning nozzle 10 located at the advanced position to the original position, the motor 32 as a driving source is rotated to the other side (reversed). Thereby, the washing nozzle 10 moves backward. The flexible rack 50 enters the rack restricting portion 33 while being guided by the rack guiding portion 34. That is, the portion that is curved by the rack restricting portion 33 gradually increases. When the cleaning nozzle 10 comes into contact with the rear end surface of the cylinder 20, the cylinder 20 moves backward together with the cleaning nozzle 10, and both return to the original position. A configuration may be adopted in which the cylinder 20 first moves backward together with the cleaning nozzle 10 due to a frictional force generated between the cleaning nozzle 10 and the cylinder 20. When the cleaning nozzle 10 moves backward, one end of the hose 40 connected thereto is displaced rearward, so that the radius of curvature of the curved portion of the hose 40 gradually increases and becomes the largest in the original position.

  In this way, the cleaning nozzle 10 moves back and forth. In addition, if the cleaning nozzle 10 has a structure capable of moving back and forth between the original position and the advance position (cleaning position), the driving mechanism of the cleaning nozzle 10 can be changed as appropriate.

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

  When the cleaning nozzle 10 is located at the original position, the cleaning water is jetted from the cleaning device toward the head portion 12 (jet port 122) of the cleaning nozzle 10. In addition, the timing which performs the said nozzle cleaning may be what. After the local cleaning, the cleaning nozzle 10 may be executed each time it returns to the original position, or when the local cleaning frequency exceeds a predetermined number or when a predetermined time has passed since the previous cleaning. You may make it do. The user may be allowed to execute nozzle cleaning at an arbitrary timing.

[Function of the cover]
The function (effect) of the covering portion 10c provided in the cleaning nozzle 10 of the human body local cleaning device 1 operating in this way will be described. Since the size of the head portion 12 (size of the outer periphery) of the cleaning nozzle 10 is slightly 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, a gap between the outer surface of the cleaning nozzle 10 and the edge of the opening 24 is covered with the head portion 12. Thus, since the head portion 12 functions as the covering portion 10c and covers the gap, it is possible to prevent water and the like from entering the apparatus (inside the base member 30) from the gap. In addition, in order for the rear end surface of the head part 12 to improve the adhesion of 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 device 1 according to the present embodiment includes a nozzle cleaning device 60 that cleans the cleaning nozzle 10 when the cleaning nozzle 10 is located at the original position. Even if the cleaning nozzle 10 is cleaned by the nozzle cleaning device 60, the nozzle cleaning water is prevented from entering the device through the gap.

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

  In the human body local cleaning device 1 in the above embodiment, the head portion 12 of the cleaning nozzle 10 formed thicker than the main body portion 11 serves as a covering portion 10 c that covers the gap between the outer surface of the cleaning nozzle 10 and the edge of the opening 24. Although described to function, the cleaning nozzle 10 may be configured as shown in FIG. The cleaning nozzle 10 shown in FIG. 7 has a boundary portion 14 that is thicker than the main body portion 11 between the head portion 12 (front end side portion) and the main body portion 11 (base end side portion). That is, by providing the bowl-shaped boundary portion 14 whose outer edge is slightly larger than the edge of the opening 24, the boundary portion 14 covers the gap when the cleaning nozzle 10 is located at the original position. Therefore, it is possible to prevent water or the like from entering the inside of the apparatus from the gap. The boundary portion 14 in this 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 material constituting the cleaning nozzle 10 can be reduced. On the other hand, the cleaning nozzle 10 in the above embodiment has a shape with fewer corners and the like, and is superior to the cleaning nozzle 10 in this example in that the cleaning nozzle 10 (head portion 12) can be easily cleaned.

  In the human body local cleaning device 1 in the above embodiment and the example shown in FIG. 7, the covering portion 10 c (head portion 12, boundary portion 14) of the cleaning nozzle 10 located in the original position is connected to the outer surface of the cleaning nozzle 10 and the cylinder The gap between the edge of the opening 24 formed in the cover 20 is described, but not only the gap (first gap) but also the outer surface of the cylinder 20 and the base member 30 (the accommodating portion 35). It is good to be comprised so that the clearance gap (2nd clearance gap) between the edges of the opened opening 36 may be covered.

  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) exists between the outer surface of the cylinder 20 and the edge of the opening 36 formed in the base member 30 (accommodating 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 in the cleaning nozzle 10 is set to be slightly larger than the outer edge of the front end surface of the cylinder 20. When the nozzle 10 is located 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 the inside of the apparatus from the first gap or the second 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 the circumference | surroundings of the cylinder 20. FIG.

  In addition, the human body local cleaning device 1 in the above embodiment and the examples shown in FIGS. 7 and 8 include a multi-stage nozzle (a two-stage nozzle unit 1u having a cleaning nozzle 10 and a cylinder 20). Although it has been described that the opening 24 for appearing and disappearing is formed in the cylinder 20, it is not limited thereto. The same technical idea can be applied even if the single cleaning nozzle 10 simply moves forward and backward with respect to the base member 30. That is, in the case where the base member 30 has an opening for the cleaning nozzle 10 to appear and disappear, when the cleaning nozzle 10 is located at the original position, the covering portion 10c (head portion 12, boundary portion 14) is cleaned. What is necessary is just to cover the clearance gap between the outer surface of the nozzle 10, and the edge of the opening formed in the base member 30 (accommodating part 35).

  Moreover, in the example shown in FIG. 7 and FIG. 8 of the human body local cleaning device 1 in the above embodiment, the covering portion 10 c (head portion 12, boundary portion 14) provided on the cleaning nozzle 10 is outside the openings 24 and 36. However, the covering portion 10c may be configured to cover the gap from the inside of the opening 24 or the opening 36. For example, a cover portion 10 c may be provided in a portion of the cleaning nozzle 10 positioned inside the cylinder 20, and the cover portion 10 c may cover the opening 24 from the inside of the cylinder 20. In addition, a cover portion 10 c may be provided in a portion of the cylinder 20 positioned inside the housing portion 35, and the cover portion 10 c may cover the opening 36 from the inside of the housing portion 35.
