Description

  The present invention relates to a human body local cleaning device including a cleaning nozzle for cleaning a local part of a human body.

  As such a human body local washing apparatus, what is described in the following patent document 1 etc. is well-known. A hose for supplying cleaning water is connected to the cleaning nozzle.

JP 2003-293431 A

  When the cleaning nozzle moves back and forth, the hose connected thereto is displaced. If the displaced hose comes into contact with other members, the hose will be worn. In addition, the contact (sliding) between the hose and other members becomes the resistance of the cleaning nozzle that moves forward and backward.

  The problem to be solved by the present invention is to provide a human body local cleaning device capable of suppressing the hose from coming into contact with other members.

  In order to solve the above-mentioned problems, a human body local cleaning apparatus according to the present invention includes a cleaning nozzle for cleaning a local part of a human body provided to be movable in a predetermined range, and one end connected to the cleaning nozzle. A hose that supplies cleaning water to the hose, and a pressing portion that is provided integrally with the cleaning nozzle so as to be along the hose and that contacts a part of the hose.

  A cylinder capable of accommodating at least a part of the cleaning nozzle, and when the cleaning nozzle is displaced relative to the cylinder, the pressing portion is provided on at least a part of the hose located in the cylinder. It should be in contact.

  The cleaning nozzle has a rack connecting portion to which a rack for transmitting power of a driving source is connected, and the pressing portion extends from the rack connecting portion along the rack, and is between the hose and the rack. It is good to provide so that it may be located in.

  A base member to which the other end of the hose is connected directly or indirectly, and a flexible rack for transmitting the power of a driving source to the cleaning nozzle, and the hose is provided between the one end and the other end. It is provided in such a way that the curvature of the curved portion changes when the cleaning nozzle advances and retreats, and the base member is provided outside the curved portion of the hose. A rack restricting portion that is positioned and restricts the shape of the flexible rack may be provided.

  The base member is provided with a rack guide portion that extends linearly from the end side of the cleaning nozzle side of the rack restricting portion, and at least a part of the pressing portion when the cleaning nozzle is located at the original position. It is preferable that at least a part of the rack guiding portion overlap.

  The human body local cleaning device according to the present invention is in a state where a pressing portion provided integrally with the cleaning nozzle along the hose is in contact with the hose. Therefore, when the cleaning nozzle moves forward and backward, the pressing portion moves while being in contact with the hose, so that the hose can be prevented from contacting other members.

  When the cleaning nozzle is displaced relative to the cylinder, it is possible to prevent the hose from coming into contact with the cylinder by adopting a structure in which the pressing portion comes into contact with at least a part of the hose located in the cylinder. it can.

  If the pressing portion is formed so as to extend from the rack connection portion and is provided so as to be positioned between the hose and the rack, the bending of the pressing portion is suppressed by the rack. That is, the rack can function as a member that suppresses the bending of the pressing portion as well as a member that transmits the power of the drive source to the cleaning nozzle.

  When the structure is provided with a rack restricting portion that regulates the shape of the rack and is located outside the curved portion of the hose whose curvature changes due to the forward and backward movement of the cleaning nozzle, the curved portion of the hose and the rack It can suppress that a control part contacts.

  When the cleaning nozzle is in the original position, contact between the rack guiding portion and the hose can be suppressed if at least a portion of the pressing portion and at least a portion of the linear rack guiding portion overlap. Further, since the hose is pressed by the pressing portion to the vicinity of the rack restricting portion, the effect of suppressing contact between the rack restricting portion and the hose is further enhanced.

  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 5 includes a cleaning nozzle 10 for cleaning a local part of the human body and a hose 40 for supplying cleaning water to the cleaning nozzle 10.

  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 at 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 head portion 11 and a rack connection portion 12. The head portion 11 is a portion provided on the front end side (front side) of the cleaning nozzle 10, and a fluid space 111 into which cleaning water flows is formed therein. In addition, a jet port 112 connected to the fluid space 111 is formed on the upper side of the head portion 11. One end of a hose 40 is connected to the cleaning nozzle 10 so as to communicate with the fluid space 111, and the cleaning water transported by the hose 40 and flowing into the fluid space 111 is located above the jet port 112 (local part of the human body). It is ejected toward. Since the shape or the like of the structure of the ejection port 112 may be any, detailed description is omitted.

  The hose 40 having one end connected to the cleaning nozzle 10 so as to communicate with the fluid space 111 is formed of a deformable material (for example, rubber), and is drawn from the rear of the cleaning nozzle 10. Note that the hose 40 only needs to be connected to the cleaning nozzle 10 so that the cleaning water to be conveyed is ejected from the ejection port 112, and any connection position or connection structure 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 cleaning nozzle 10.

  A rack connection portion 12 is provided on the rear end upper side of the cleaning nozzle 10. One end of a flexible rack 50 is connected to the rack connection portion 12. A holding part 121 is provided so as to extend rearward from the rack connection part 12. Specifically, the pressing portion 121 is a plate-like portion that extends linearly from the lower side of the rack connecting portion 12. As described above, the pressing portion 121 is provided integrally with the cleaning nozzle 10 (may be formed integrally with the cleaning nozzle 10 or may be a portion formed separately and fixed to the nozzle body side. Good). Therefore, when the cleaning nozzle 10 moves back and forth, the presser 121 moves with it. The holding part 121 has a shape (width, thickness, etc.) that can hold the part of the hose 40 that contacts the holding part 121 upward (deforms) and presses it from above to prevent the displacement. If you do. For example, if the structure is such that two or more hoses 40 are connected to one cleaning nozzle 10, the shape of the pressing portion 121 may be set so that the displacement of all the hoses 40 can be prevented.

  The holding part 121 extends along the hose 40 drawn from the rear of the cleaning nozzle 10. More specifically, the hose 40 extends along a portion extending in the front-rear direction (a portion closer to the cleaning nozzle 10 (one end side) than a curved portion described later). That is, the holding part 121 contacts a part between one end and the other end of the hose 40 along the front-rear direction. Further, the pressing portion 121 is positioned so as to be sandwiched between the flexible rack 50 and the hose 40. In the present embodiment, there is a small gap between the flexible rack 50 and the pressing portion 121 in a state where the cleaning nozzle 10 (nozzle unit 1u) is located at the advanced position (details will be described later). Further, the upper side of the front end (rear end) of the pressing portion 121 has a chamfered shape.

  The cylinder 20 is a cylindrical member into which a portion other than the head portion 11 of the cleaning nozzle 10 can 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 portion that enters the cylinder 20. A hooking portion 21 is formed on the upper front side of the cylinder 20, and when the relative position of the cleaning nozzle 10 with respect to the cylinder 20 comes to the forefront, the hooking portion 21 and the rack connecting portion 12 come into contact with each other. As a result, the cleaning nozzle 10 cannot move further forward with respect to the cylinder 20. That is, the rack connecting portion 12 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.

  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 hose insertion hole 22 is also a hole through which the pressing part 121 passes along with the hose 40.

  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. In addition, a valve (not shown) or the like 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 ejected from the ejection port 112). 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 that 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 (rack connection portion 12), and meshes with the flexible rack 50 that is 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. Further, the lower side of the end portion (front end) of the rack guide portion 34 has a chamfered shape.

  Further, the human body local cleaning device 1 according to the present embodiment includes a nozzle cleaning device 60 for cleaning the cleaning nozzle 10. Since the nozzle cleaning device 60 may have any configuration, detailed description thereof is omitted. Such a device may not be provided.

[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 12 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 112. 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 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 11 and the cylinder 20 are located inside the accommodating portion 35.

[Function of holding part]
The function (effect) of the pressing part 121 included in the human body local cleaning device 1 operating in this way will be described in detail. As described above, since the pressing portion 121 is provided integrally with the cleaning nozzle 10, the pressing portion 121 moves along with the cleaning nozzle 10 along the front-rear direction. Moreover, the part along the front-back direction of the hose 40 with the washing nozzle 10 also moves along the front-rear direction. Therefore, even if the cleaning nozzle 10 moves back and forth, the portion of the hose 40 with which the pressing portion 121 contacts hardly changes.

  When the cleaning nozzle 10 is located at the advanced position, the pressing portion 121 is located within the cylinder 20. That is, the pressing part 121 is in a state of contacting at least a part of a portion of the hose 40 located in the cylinder 20 (see FIG. 5). Therefore, the hose 40 is prevented from coming into contact with the cylinder 20 when the cleaning nozzle 10 moves from the advanced position toward the original position. Specifically, since the curved portion of the hose 40 in the present embodiment is curved downward from one end side connected to the cleaning nozzle 10, the front-rear direction of the hose 40 is caused by the stress generated in the curved portion. When the portion extending along the hose 40 is to be displaced so as to bend upward, the displacement is pressed down by the holding portion 121 located on the upper side of the hose 40 (the holding portion 121 is provided on the side where the hose 40 is easily displaced). Therefore, the contact between the hose 40 and the cylinder 20 is suppressed.

  As the cleaning nozzle 10 moves backward, the presser 121 passes through the hose insertion hole 22 formed in the cylinder 20 together with the hose 40 and enters the accommodating portion 35. That is, the rack guide portion 34 formed on the base member 30 is approached. Eventually, the pressing portion 121 enters a state below the rack guiding portion 34. As described above, in the present embodiment, in the state where the cleaning nozzle 10 is located at the advanced position, a gap is set between the flexible rack 50 and the pressing portion 121, and the rack guide portion 34 is set in the gap. Goes in. Thus, when the cleaning nozzle 10 is located at the original position, at least a part of the pressing part 121 and at least a part of the rack guiding part 34 are overlapped in the vertical direction (see FIG. 3).

  In this embodiment, when the cleaning nozzle 10 is located at the original position, the pressing portion 121 is set so as to overlap almost the entire rack guide portion 34. That is, when the cleaning nozzle 10 is located at the original position, the front end (rear end) of the pressing portion 121 is set to be located immediately before the curved rack regulating portion 33. In order to increase the effect of suppressing the displacement of the hose 40, it is preferable to lengthen the pressing portion 121 and increase the area where the pressing portion 121 and the hose 40 are in contact. However, if the pressing portion 121 is made too long, the curved rack regulating portion 33 and the pressing portion 121 interfere with each other when the cleaning nozzle 10 is located at the original position. Therefore, by setting the length of the pressing portion 121 to the maximum in a range where the rack regulating portion 33 and the pressing portion 121 do not interfere with each other, that is, by setting the pressing portion 121 so as to overlap almost the entire rack guiding portion 34, the pressing portion 121. It is set as the structure which raised the effect which suppresses the displacement of the hose 40 by maximum.

  Since it is configured in this manner, at least a portion of the hose 40 that is in contact with the pressing portion 121 does not contact the rack guide portion 34 (inner linear protrusion 342). Further, the position restricting effect by the pressing portion 121 (so that the hose is not displaced upward) is also applied to the portion on the other end side (the portion not in contact with the pressing portion 121) with respect to the portion in contact with the pressing portion 121 in the hose 40. (Effect) extends to the relevant part (compared to the case where the pressing part 121 is not provided), so that the rack guiding part 34 is prevented from contacting.

  Further, as the cleaning nozzle 10 moves backward, the radius of curvature of the curved portion of the hose 40 increases, so that the pressing portion 121 moves to a position where at least a portion thereof enters the lower side of the rack guiding portion 34, that is, the rack. Since the displacement of the hose 40 is restricted to the vicinity of the restricting portion 33, the curved portion of the hose 40 and the rack restricting portion 33 are prevented from coming into contact (as compared to the case where the pressing portion 121 is not provided). The

  Here, as shown in FIG. 6, in the present embodiment, the upper side of the front end (rear end) of the pressing portion 121 has a chamfered shape (curved surface (R surface) or inclined surface 121a). Further, the lower side of the end portion (front end) of the rack guide portion 34 has a chamfered shape (curved surface (R surface) or inclined surface 342a). As a result, the pressing portion 121 approaches the rack guiding portion 34 and prevents the end portions of the pressing portion 121 and the rack guiding portion 34 from colliding with each other when entering the lower side of the rack guiding portion 34. That is, the holding part 121 enters the lower side of the rack guiding part 34 smoothly.

  Thus, the pressing part 121 that restricts the displacement of the hose 40 is provided so as to be positioned between the hose 40 and the rack. Therefore, even if the pressing portion 121 is likely to be bent by the hose 40 that is about to be displaced upward (on the pressing portion 121 side), the bending is suppressed by the rack. That is, the rack in the present embodiment functions not only as a member that transmits the power of the drive source to the cleaning nozzle 10 but also as a member that suppresses the bending of the pressing portion 121.

  As described above, in the human body local cleaning device 1 according to the present embodiment, the hose 40 is prevented from coming into contact with other members by the pressing portion 121 provided integrally with the cleaning nozzle 10. Therefore, the hose 40 is abraded due to contact with other members, and the contact (sliding) of the hose 40 with other members is prevented from causing resistance of the cleaning nozzle 10 that moves forward and backward.

[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.

  The human body local cleaning device 1 in the above embodiment has been described as including a multistage nozzle (a two-stage nozzle unit 1u having the cleaning nozzle 10 and the cylinder 20), but 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. Further, the number of nozzle stages is not limited.

  In the human body local cleaning device 1 in the above embodiment, it has been described that a part of the hose 40 is curved. However, if the hose 40 is curved, the hose 40 may be caused by the stress generated by the bending. Since there is a high possibility of contact with the member, it is significant to provide the pressing portion 121, and it is not always necessary that the portion is curved. Similarly, although it has been described that the flexible rack 50 is used as a member that transmits the power of the driving source to the cleaning nozzle 10, it is not limited to this.

  In the human body local cleaning apparatus 1 in the above embodiment, the pressing part 121 is provided so as to press a part of the hose 40 from above (the pressing part 121 is provided in a direction in which the hose 40 is easily displaced). Although described, it is not limited to such a configuration. For example, it is good also as the holding | suppressing part 121 of a shape surrounding the circumference | surroundings of the hose 40. FIG.
