JP 2001-271403 A

  However, the above-described local cleaning device includes a valve switching body that is connected to the valve operating body in the longitudinal direction in order to supply cleaning water from the side into the nozzle. In order to ensure it, the total length of the device becomes long. Further, when supplying the cleaning water from the side into the nozzle body, a sealing material (O-ring) for preventing water leakage is required, which increases the number of parts and increases the cost.

  The main purpose of the local cleaning apparatus of the present invention is to ensure the necessary advance / retreat amount of the nozzle while shortening the total length of the apparatus and to prevent the hose supplying cleaning water to the nozzle from being damaged.

  The local cleaning apparatus of the present invention employs the following means in order to achieve the main object described above.

The local cleaning apparatus of the present invention is
A local cleaning device for cleaning a local part of a human body,
A cylindrical rotating body having a spiral groove on the inner peripheral surface and having an opening at the front end and the rear end;
A rotating gear provided coaxially with the rotating body on the rotating body;
A motor for rotating the rotating gear;
Provided inside the rotating body, having a spout for ejecting washing water at the front end and a fitting part that fits the spiral groove at the rear end, and advances and retreats as the rotating body rotates. A movable nozzle,
A hose connected to the nozzle through the opening at the rear end of the rotating body and capable of supplying cleaning water to the nozzle;
A support member that has an insertion hole that is inserted into the hose, is attached to a rear end of the rotating body so as to be relatively rotatable, and supports the hose;
It is a summary to provide.

  In this local cleaning device of the present invention, one end of the hose is connected to the internal nozzle through the opening at the rear end of the rotating body, and the cleaning water is supplied from the hose to the inside of the nozzle. As compared with the case of supplying the nozzle, it is possible to secure the necessary advancement / retraction amount of the nozzle while shortening the overall length of the apparatus. Further, the cost can be reduced by eliminating the need for a seal portion or the like. In addition, since the hose is supported by the support member attached to the rear end portion of the rotating body so as to be relatively rotatable, the hose can be prevented from rotating even if the rotating body rotates. As a result, it is possible to prevent the hose from being damaged by suppressing the hose from being rubbed or twisted.

  In such a local cleaning device of the present invention, the rotating body may have an annular groove on the inner peripheral surface of the rear end portion, and the support member may have a protrusion that engages with the groove. If it carries out like this, a hose can be appropriately supported by simple structure.

  In the local cleaning device of this aspect of the present invention, the protrusion may be an annular rib, or the protrusion may be a flexible claw. In the former case, even if the hose moves as the nozzle moves forward and backward, it is possible to more reliably suppress the support member from coming off the rotating member. In the latter case, it is easy to engage the protrusion of the support member with the groove of the rotating body, and the assembling property can be improved.

  The cylinder 40 is a cylindrical rotating body whose front end and rear end are open, and has an inner diameter slightly larger than the outer diameter of the nozzle 30 so as to surround the nozzle 30. FIG. 5 is an external perspective view of the cylinder 40, and FIG. 6 is an exploded perspective view of the cylinder 40. The cylinder 40 is formed by abutting the end faces in the circumferential direction of the two semi-cylindrical members 41 and 42. As shown in FIGS. 5 and 6, the outer circumferential surfaces of the semi-cylindrical members 41 and 42 are semicircular so as to form an annular shape with the end surfaces in the circumferential direction of the semi-cylindrical members 41 and 42 being in contact with each other. The formed outer peripheral rib 43 is formed. Further, as shown in FIG. 6, a plurality of inner peripheral ribs 44 extending at an inclination with respect to the axial direction of the cylinder 40 are formed on the inner peripheral surfaces of the semi-cylindrical members 41 and 42. The plurality of inner peripheral ribs 44 form a spiral groove 44a in which the grooves between the adjacent inner peripheral ribs 44 are spirally connected in a state where the end faces in the circumferential direction of the semi-cylindrical members 41 and 42 are abutted with each other. In this embodiment, as shown in FIG. 6, the spiral groove 44a is formed such that the pitch between adjacent grooves in the front end portion and the rear end portion in the axial direction of the cylinder 40 is narrower than that in the central portion. Yes.

  Further, the outer peripheral surfaces of the rear end portions of the semi-cylindrical members 41 and 42 are annular in a state in which the end surfaces in the circumferential direction of the semi-cylindrical members 41 and 42 are abutted with each other, as shown in FIGS. A rotating gear 45 formed in a semicircular shape is provided. In the present embodiment, the rotation gear 45 is formed to have an outer diameter smaller than the outer diameter of the case 50 so as not to protrude from the outer diameter of the case 50 (see FIG. 2). The rotation gear 45 is meshed with a drive gear 25 attached to the rotation shaft of the motor 24, and the cylinder 40 rotates integrally with the rotation gear 45 when the rotation gear 45 is driven to rotate by the motor 24. A projection 35 provided on the outer peripheral surface of the rear end portion of the nozzle 30 is fitted into the spiral groove 44 a formed on the inner peripheral surface of the cylinder 40, and the projection 35 is formed by the rotation of the cylinder 40. While moving relatively along the spiral groove 44a, it moves back and forth between the accommodation position and the advance position.

  Further, in the present embodiment, the semi-cylindrical members 41 and 42 are injections that inject and inject a resin material into a space between a concave mold that forms the outer peripheral surface and a convex mold that forms the inner peripheral surface, and cool and solidify the resin material. Formed by molding, the semi-cylindrical members 41, 42 are integrally formed with a rotating gear 45, an outer peripheral rib 43, and an inner peripheral rib 44. Further, as shown in FIG. 6, the inner peripheral ribs 44 are not formed at both ends in the circumferential direction of the inner peripheral surfaces of the semi-cylindrical members 41, 42, and are not stamped (convex-shaped). (Die cutting) can be performed smoothly.

  Further, as shown in FIG. 6, the end surfaces in the circumferential direction of the semi-cylindrical members 41, 42 are abutted against the inner peripheral surface (the inner peripheral surface of the rotating gear 45) of the rear end portions of the semi-cylindrical members 41, 42. An engagement groove 48 formed in a semicircular shape is formed so as to form an annular shape in the above state. An annular cylinder tail 49 is rotatably attached to the engagement groove 48. FIG. 7 is a front view, a top view, and a side view of the cylinder tail 49. As shown in the drawing, an oblong insertion hole 49 a into which the hoses 21 and 22 are inserted is formed at the center of the cylinder tail 49, and the engagement groove 48 is engaged with the outer periphery of the cylinder tail 49. An annular engagement rib 49b is formed.

  The case 50 is a cylindrical member having an open front end and a rear end, and has an inner diameter slightly larger than the outer diameter of the cylinder 40 so as to surround the cylinder 40 and rotatably support the cylinder 40. As shown in FIG. 3, the case 50 is formed by abutting the end faces in the circumferential direction of the two semi-cylindrical members 51 and 52. A semicircular inner circumferential groove 53 is formed on the inner circumferential surface of the case 50 so as to form an annular shape in a state where the circumferential end surfaces of the two semicylindrical members 51 and 52 face each other. 53 is fitted with an outer peripheral rib 43 of the cylinder 40. In the present embodiment, the inner circumferential groove 53 has a depth shallower than the height of the outer circumferential rib 43, and the cylinder 50 is supported by the case 50 so as to be rotatable with a small frictional resistance. Further, a fixing plate 52a extending in the radial direction is integrally provided on the outer peripheral surface of the rear end portion of the case 50 (semi-cylindrical member 52), and the housing of the motor 24 is fixed to the fixing plate 52a.

  FIG. 8 is an external perspective view of a semi-cylindrical member 52 that constitutes a part of the case 50. As shown in the drawing, the semi-cylindrical member 52 on the lower surface side of the case 50 is provided with a guide rib 54 protruding upward. The guide rib 54 is formed on the distal end side of the support surface that supports the outer peripheral surface of the cylinder 40 of the case 50, and guides the forward / backward movement of the nozzle 31 by fitting in the guide groove 31 c of the nozzle 31. Thereby, the rotation of the nozzle 30 accompanying the rotation of the cylinder 40 is prevented. Therefore, in the nozzle unit 20 of the present embodiment, the nozzle 30 can be formed in a cylindrical shape, dirt is less likely to adhere to the nozzle 30, and cleanliness can be further improved.

  The nozzle cleaner 60 is attached to the upper surface of the tip portion of the case 50 and has an ejection hole that ejects cleaning water toward the upper surface of the nozzle 30. One end of the hose 23 is connected to the nozzle cleaner 60, and a switching valve is connected to the other end of the hose 23.

  The switching valve switches whether the supply destination of the cleaning water in the cleaning water flow path downstream from the pulsation pump is ejected from any of the plurality of nozzle holes 31a, 31b and the nozzle cleaning device 60, and is driven by a motor, for example. It is configured as a rotary valve.

  Next, the operation of the sanitary washing toilet seat device 10 (nozzle unit 20 of the local washing device) of the present embodiment thus configured will be described. The control device of the sanitary washing toilet seat device 10 determines that the user is seated on the toilet seat 14 by the seating sensor 13 and that the washing switch for butt on the operation panel 18 has been pressed to instruct the start of the tail washing. If it determines, the rotation gear 45 which meshes with the drive gear 25 will be rotated by the motor 24, and the cylinder 40 will be rotated. When the cylinder 40 rotates, the plurality of protrusions 35 provided on the nozzle 30 relatively move along the spiral groove 44a formed on the inner peripheral surface of the cylinder 40, and the nozzle 30 moves toward the washing position for the butt washing. To advance. When the nozzle 30 reaches the cleaning position, the control device controls the switching valve (motor) so that the cleaning water from the pulsation pump is supplied to the nozzle hole 32 a of the nozzle 30 via the hose 21. As a result, washing water is ejected from the nozzle hole 32a toward the anus of the human body, and butt washing is started. When the control device determines that the front switch (cleaning position adjustment switch) has been pressed and an instruction to change the cleaning position to the front is instructed, the motor 24 rotates the cylinder 40 to advance the nozzle 30 by a predetermined amount. Further, when the control device determines that the rear switch (cleaning position adjustment switch) has been pressed to instruct to change the cleaning position backward, the motor 24 reversely rotates the cylinder 40 to retract the nozzle 30 by a predetermined amount. . When the control device determines that the stop switch of the operation panel 18 is pressed and the stop of the buttocks cleaning is instructed, the control device stops the water supply to the nozzle 30. Then, the rotating gear 45 is reversely rotated by the motor 24 so that the nozzle 30 is retracted toward the accommodation position and is accommodated in the cylinder 40. The control device controls the switching valve (motor) so that the cleaning water is ejected from the nozzle cleaning device 60 toward the nozzle 30 when the nozzle 30 is moving from the cleaning position to the storage position or when the nozzle 30 reaches the storage position. The nozzle 30 is washed.

  Further, when the control device determines that the user is seated on the toilet seat 14 by the seating sensor 13 and determines that the bidet cleaning switch of the operation panel 18 is pressed and the start of bidet cleaning is instructed, the motor 24, the cylinder 40 is rotated, and the nozzle 30 is advanced toward the cleaning position for bidet cleaning. When the nozzle 30 reaches the cleaning position, the control device controls the switching valve (motor) so that the cleaning water from the pulsation pump is supplied to the nozzle hole 32 b of the nozzle 30 via the hose 22. Thereby, washing water is ejected from the nozzle hole 32b toward the bidet part of the human body, and bidet washing is started. When the control device determines that the front switch (cleaning position adjustment switch) has been pressed and an instruction to change the cleaning position to the front is instructed, the motor 24 rotates the cylinder 40 to advance the nozzle 30 by a predetermined amount. Further, when the control device determines that the rear switch (cleaning position adjustment switch) has been pressed to instruct to change the cleaning position backward, the motor 24 reversely rotates the cylinder 40 to retract the nozzle 30 by a predetermined amount. . When the control device determines that the stop switch of the operation panel 18 is pressed and the stop of the bidet cleaning is instructed, the control device stops the water supply to the nozzle 30. Then, the rotating gear 45 is reversely rotated by the motor 24 so that the nozzle 30 is retracted toward the accommodation position and is accommodated in the cylinder 40. The control device controls the switching valve (motor) so that the cleaning water is ejected from the nozzle cleaning device 60 toward the nozzle 30 when the nozzle 30 is moving from the cleaning position to the storage position or when the nozzle 30 reaches the storage position. The nozzle 30 is washed.

  In this manner, the nozzle 30 moves forward and backward by converting the rotational motion of the cylinder 40 into a linear motion as the projection 35 provided at the rear end slides along the spiral groove 44a. As described above, the pitch between adjacent grooves of the spiral groove 44a is narrower at the front and rear ends of the cylinder 40 than at the center. Therefore, the advance / retreat amount of the nozzle 30 per unit rotation of the cylinder 40 is small in the vicinity of the storage position and in the vicinity of the advance position, and is large at an intermediate position between them. That is, the nozzle 30 moves at a relatively high speed until it approaches the cleaning position when the butt cleaning or the bidet cleaning is started, and moves at a relatively low speed when it approaches the cleaning position. Further, the nozzle 30 moves at a relatively high speed until it approaches the storage position after the butt cleaning and the bidet cleaning, and moves at a relatively low speed when it approaches the storage position. Thereby, the positioning accuracy of the cleaning position and the storage position of the nozzle 30 can be improved while increasing the moving speed between the storage position of the nozzle 30 and the advance position.

  Further, as shown in FIGS. 9 and 10, the hoses 21 and 22 for supplying the cleaning water to the nozzle 30 are inserted from the insertion holes 49 a of the cylinder tail 49 attached to the rear end portion of the cylinder 40 to the nozzle 30. Connected. The cylinder tail 49 is attached so as to be rotatable relative to the cylinder 40, and the hoses 21 and 22 are supported by the cylinder tail 49 without rotating with the cylinder 40 even when the cylinder 40 is rotated. ing. Thereby, rubbing and twisting of the hoses 21 and 22 are suppressed, and damage is prevented. Furthermore, in this embodiment, the corner of the opening edge of the insertion hole 49a is formed by a smooth convex curved surface as shown in FIG. 10, and when the hoses 21 and 22 are interlocked with the forward / backward movement of the nozzle 30. The hoses 21 and 22 are prevented from rubbing and being damaged at the corners of the opening edge.

  In the local cleaning device of the present embodiment described above, one end of the hoses 21 and 22 is connected to the internal nozzle 30 through the opening at the rear end of the cylinder 40, and cleaning water is supplied from the hoses 21 and 22 into the nozzle 30. To do. This makes it possible to secure the necessary advance / retreat amount of the nozzle 30 while shortening the overall length of the apparatus as compared with the case where cleaning water is supplied into the nozzle 30 from the side of the case. Further, the cost can be reduced by eliminating the need for a seal portion or the like. In addition, since the hoses 21 and 22 are supported by the cylinder tail 49 attached to the rear end of the cylinder 40 so as to be relatively rotatable, the hoses 21 and 22 are prevented from rotating even when the cylinder 40 rotates. be able to. As a result, the hoses 21 and 22 can be prevented from rubbing and twisting to prevent the hoses 21 and 22 from being damaged.

  In the embodiment, the cylinder tail 49 is provided with the annular engagement rib 49b that engages with the annular engagement groove 48 of the cylinder 40 on the outer peripheral portion, but the present invention is not limited to this. As shown in the cylinder tail 149 of the modified example of FIG. 12, a plurality (two) of engaging ribs 149b divided in the circumferential direction may be provided. Further, as shown in the cylinder tail 249 of the modified example of FIGS. 13 and 14, a flexible engagement claw 249 b having slits 249 c formed on both sides may be provided instead of the engagement rib. In the latter case, the cylinder tail 249 can be assembled by directly pushing the cylinder tail 249 into the rear end of the cylindrical cylinder 40, and the assemblability can be improved.

  In the embodiment, the nozzle 30 is formed in a cylindrical shape, but is not limited thereto, and may be formed in a non-circular shape such as an oval or an ellipse. In this case, if the opening along the outer shape of the nozzle is formed in the tip surface of the case 50, the rotation of the nozzle accompanying the rotation of the cylinder 40 can be prevented without providing the guide groove 31c and the guide rib 54.

  In the embodiment, the spiral groove 44a is formed so that the distance between adjacent grooves at the front end portion and the rear end portion of the cylinder 40 is narrower than that at the center portion. However, the present invention is not limited to this. The distance between adjacent grooves at the front end of the cylinder may be narrower than the center and the rear end, and the distance between adjacent grooves at the rear end of the cylinder 40 may be the center and the front. It is good also as what is formed so that it may become narrower than a part. Further, all the intervals between adjacent grooves of the spiral groove may be uniform.

  In the embodiment, the rotation gear 45 is divided and provided in each of the semi-cylindrical members 41 and 42 so as to form an annular shape with the end faces in the circumferential direction of the semi-cylindrical members 41 and 42 being in contact with each other. Further, a configuration may be adopted in which an annular rotation gear that is not divided is provided on one of the semi-cylindrical members 41 and 42 and a rotation gear is not provided on the other.

  In the embodiment, the annular outer circumferential rib 43 is formed on the outer circumferential surface of the cylinder 40, and the annular inner circumferential groove 53 fitted to the outer circumferential rib 43 is formed on the inner circumferential surface of the case 50. An outer peripheral groove may be formed on the outer peripheral surface, and an inner peripheral rib fitted to the outer peripheral groove may be formed on the inner peripheral surface of the case 50. The rib is not necessarily limited to an annular shape, and may be formed in an arc shape and may have any shape as long as it can be fitted into the groove.

  In the embodiment, the plurality of protrusions 35 are provided on the outer peripheral surface of the rear end portion of the nozzle 30 as the fitting portion to be fitted to the spiral groove 44a of the cylinder 40. However, the present invention is not limited to this. Balls that can roll at equiangular intervals may be disposed on the outer peripheral surface of the rear end portion of the main body 31.

  In the embodiment, the external gear 45 is provided on the outer peripheral surface of the rear end portion of the cylinder 40 so as to rotate coaxially with the cylinder 40. However, the present invention is not limited to this, and the rear end surface of the cylinder 40 is not limited thereto. Further, an annular bevel gear such as a face gear may be provided so as to rotate coaxially with the cylinder 40, and the motor may be arranged so that a drive gear attached to the rotation shaft meshes with the bevel gear.

  In the embodiment, the cylinder 40 is formed by the two semi-cylindrical members 41 and 42, but is not limited thereto, and may be formed by a single cylindrical member, or three or more. It may be formed by a member curved in a circular arc shape. When the cylinder 40 is formed of a single cylindrical member, the above-described cylinder tail 249 of FIGS. 13 and 14 can be used as a cylinder tail that supports the hoses 21 and 22.

  In the embodiment, the two hoses 21 and 22 are connected to the nozzle 30 and the two nozzle holes 31a and 31b for ejecting the washing water from the corresponding hoses are used for the buttocks washing and the bidet washing, respectively. They may be used for other different applications, such as for a buttocks powerful cleaning and a buttocks mild cleaning. Moreover, it is good also as a thing provided separately with a nozzle (nozzle unit) for every use. In this case, as described above, the outer diameter of the rotating gear 45 is made smaller than the outer diameter of the case 50 so that the rotating gear 45 provided at the rear end of the cylinder 40 does not protrude from the outer diameter of the case 50. Therefore, even when a plurality of nozzle units are arranged side by side, the entire unit can be made more compact.

  In the embodiment, the nozzle 30 is provided with two nozzle holes 31a and 31b to which the two hoses 21 and 22 are connected and the washing water from the corresponding hose is ejected. However, one hose is connected. Moreover, it is good also as what has one nozzle hole which ejects the washing water from the said hose. In this case, the insertion hole 49a of the cylinder tail 49 may be formed in a circular shape.
