Japanese Patent Laid-Open No. 2005-180078

  The above-described human body cleaning device disclosed in Patent Document 1 performs pseudo-cleaning over a wide area of the human body part by controlling nozzle vibration and water pressure. As described above, since a pseudo wide range of cleaning is performed, it is difficult for the user to clean the entire local area at once. Moreover, in a washing | cleaning part, a flow feeling changes intermittently because a washing water hits a human body local part intermittently. For this reason, the user may not obtain a satisfactory flow rate feeling. Therefore, the user cannot switch and select the wide range cleaning with a constant flow rate at the time of local cleaning of the human body. Further, when the cleaning range is adjusted with a vibrator that slides in the nozzle and intermittently opens and closes the air holes, it is necessary to improve the sealing property between the nozzle and the vibrator. In the vibrator of Patent Document 1, since the seal structure is not provided, there is a possibility that the cleaning water may enter the operation portion of the human body cleaning device and cause a malfunction in the nozzle operation.

  Therefore, the present invention provides a human body cleaning device that can suppress the malfunction of the nozzle due to the intrusion of cleaning water when the user adjusts the range in which the local part of the human body is cleaned.

  The means taken in order to solve the above-mentioned problems are a bottomed hollow cylindrical shape, an outer nozzle having a plurality of cleaning ports arranged in parallel and extending from the cavity, and an axial direction of the outer nozzle. A first seal member provided between the outer nozzle and the inner nozzle, and an inner nozzle having a supply portion that moves in the hollow portion along the hollow portion extending from the hollow portion and supplies cleaning water to the cleaning port. And a driving means for moving the outer nozzle and the inner nozzle back and forth, sliding in the cavity in conjunction with the inner nozzle, and having a sliding member that adjusts the opening / closing amount of the parallel cleaning ports, The seal member is configured to seal the axial direction by being sandwiched between the sliding member and the inner wall of the cavity.

  In addition, the cleaning port is provided at the tip of the hollow portion and has a structure having a first cleaning port positioned in front of the advancing / retreating direction and a second cleaning port positioned in the rear.

The cavity has a first cavity communicating with the first cleaning port and a second cavity communicating with the second cleaning port, and the sliding member has a larger volume than the first cavity. The sliding member is preferably provided with a second seal member for sealing the radial direction of the hollow portion.

  The seal member is preferably provided so that the first seal member and the second seal member are integrated to cover the sliding member.

  According to the present invention, the human body cleaning apparatus is provided with a seal member that adjusts the range of cleaning of the human body local area by sliding the inner nozzle 40 in the outer nozzle 30 and seals in the axial direction of the cleaning nozzle. Thus, when adjusting the range of the cleaning port, friction due to sliding between the sliding member and the cavity can be suppressed, and durability against wear of the seal member can be improved. Furthermore, the human body cleaning apparatus can ensure the strong sealing performance because the elastic deformation of the sealing member can be efficiently generated by the contact between the inner wall of the cavity and the sliding member. Thereby, the human body washing | cleaning apparatus can suppress that washing | cleaning water penetrate | invades into the operation | movement part at the time of adjusting a washing port, and a malfunction generate | occur | produces in nozzle operation | movement.

  This human body cleaning device can be cleaned in the area that suits the user's preference by making the first cleaning port a normal range of cleaning and the second cleaning port a wide range of cleaning. It is possible to perform cleaning while maintaining the flow rate of.

  Furthermore, the human body cleaning apparatus provides a first cavity portion and a second cavity portion as the cavities, and the first cleaning port and the second cleaning port are provided in each of the cavities, thereby clearly adjusting the cleaning range. Can be. Since the sliding member slides in the second cavity, the first cavity located forward in the forward / backward direction is always in a state that can be normally cleaned, and cleaning is performed only by adjusting the second cleaning port when performing wide-area cleaning. The range can be adjusted. Further, if the first cavity portion and the second cavity portion are configured to have different volumes, the cleaning water discharged from the first cleaning port of the first cavity portion having a smaller volume than the second cavity portion during normal cleaning. Water pressure can be secured sufficiently, and when washing over a wide area, the volume is increased, so that the amount of washing water can be increased even if the water pressure drops, and the human body washing device should provide comfortable washing for the user. Can do.

  Further, the human body cleaning device is provided with the second seal member that seals the radial direction of the hollow portion on the sliding member, so that the cleaning port can be closed at the same time as sealing between the sliding member and the hollow portion. Therefore, the sealing performance is improved, and the cleaning range can be finely adjusted.

  In addition, since the first and second sealing members are integrally molded and provided to cover the sliding member, the human body cleaning device improves the sealing performance and durability against sliding wear. Let

FIG. 1 shows a perspective view when the human body cleaning device 1 is attached to the toilet 2, and FIG. 2 shows a side view of the human body cleaning device 1 during cleaning.

  As shown in FIGS. 1 and 2, the human body washing apparatus 1 has a main body housing 10 to which the toilet seat 3 can be rotated attached to the toilet bowl 2, and a main body 20 disposed in the main body housing 10. Outer nozzle 30 and inner nozzle 40 which are cleaning nozzles for performing local cleaning, and driving means for driving the cleaning nozzle (a driving mechanism 50 for moving the outer nozzle 30 and inner nozzle 40 back and forth, and the outer nozzle 30 and inner nozzle 40 And a latch mechanism 60) for bringing them into a connected state. The drive mechanism 50 advances the cleaning nozzle to a cleaning position by meshing a rack 51 provided on the lower surface of the outer nozzle 30 and a pinion 43 rotated by a motor 52 attached to the main body 20 that supports the outer nozzle 30. Let This cleaning position is a position suitable for local cleaning of the human body, and cleaning is performed when the cleaning nozzle reaches the cleaning position. Further, since the motor 52 can be rotated in both the forward direction and the backward direction, for example, by control by a pulse wave, the cleaning nozzle can be moved in both the forward and backward directions. Further, the cleaning range is changed by adjusting the position of the outer nozzle 30 and the inner nozzle 40 by the drive mechanism 50 and adjusting the opening / closing amounts of a plurality of cleaning ports provided in the outer nozzle 30. The rear part of the outer nozzle 30 and the inner nozzle 40 is provided with an outer nozzle 30 for operating the outer nozzle 30 and the inner nozzle 40 of the cleaning nozzle while maintaining a certain state up to the cleaning position and adjusting a cleaning range. A latch mechanism 60 that adjusts and holds the positional relationship of the inner nozzle 40 is provided.

  Next, operation | movement of the human body washing | cleaning apparatus 1 in embodiment of this invention is demonstrated with reference to FIG. FIG. 3 is an explanatory diagram showing the operation of the outer nozzle 30 and the inner nozzle 40 shown in FIG.

  FIG. 3A shows a state in which cleaning nozzles (a general term for the outer nozzle 30 and the inner nozzle 40) are accommodated. The inner nozzle 40 of the cleaning nozzle has a protrusion 41 that protrudes in a direction perpendicular to the advancing and retreating direction of the cleaning nozzle, and the protrusion 41 slides on the sliding portion 21 provided on the main body 20. Further, the sliding portion 21 has a structure in which the movement range of the inner nozzle 40 is restricted by the protrusion 41 being locked by the first locking portion 21a and the second locking portion 21b provided at both ends. It has become. The outer nozzle 30 includes a plurality of cleaning ports 31 for discharging cleaning water, and the front cleaning port 31 is a first cleaning port 31a and the rear cleaning port 31 is a second cleaning port 31b. Further, the outer nozzle 30 has a hollow cylindrical portion 32 with a bottom, and the hollow portion 30 includes a first cavity portion 32a on the distal end side communicating with the first cleaning port 31a, and a second cleaning port. A second cavity 32b having a larger diameter than the first cavity 32a is provided in communication with 31b, and the first cavity 32a and the second cavity 32b communicate with each other. Further, the outer nozzle 30 communicates with the second cavity 32b through a hollow portion 33 on which the inner nozzle 40 slides. The inner nozzle 40 is provided with a sliding member 42 that slides in the second cavity portion 32b in conjunction with the movement of the inner nozzle 40 and a hollow supply portion 43 that supplies cleaning water. The sliding member 42 also contacts the second cavity 32b in the axial direction. The second cavity portion 32b has an inner wall 34 that contacts the sliding member 42, and is provided with a first inner wall 34a that contacts the first cavity portion 32a and a second inner wall 34b that contacts the hollow portion 33 side. ing. A seal member 70 (for example, an elastic member) is provided between the sliding member 42 and the first inner wall 34a and the second inner wall 34b of the second cavity portion 32b, and the seal member 70 serves as the second cavity portion. It has a structure that seals the axial direction of 32b. Further, in the seal member 70 of the present embodiment, the first seal member 71 that seals the axial direction of the second cavity 32b and the second seal member 72 that seals also in the radial direction of the second cavity 32b are integrated. It is formed and provided to cover the sliding member 42. The seal member 70 is sandwiched between the inner wall 34 and the sliding member 42 in the second cavity portion 32b, so that a gap generated between the inner wall 34 and the sliding member 42 can be filled, for example, due to elastic deformation. Become. Due to the structure of the outer nozzle 30 and the inner nozzle 40, the first cleaning port 31a can always discharge fluid, and the state of the normal cleaning range in which the second cleaning port 31b is blocked is maintained. The outer nozzle 30 is provided with an air supply port 35 for sending air into the cleaning water. The air supply port 35 communicates with a plurality of intake holes 44 provided in the inner nozzle 40 so that air can be sent into the cleaning water.

  FIG. 3B shows the cleaning nozzle at the cleaning position. At this time, the outer nozzle 30 and the inner nozzle 40 are moved forward together by the drive mechanism 50 and the latch mechanism 60 to the cleaning position. When advancing to this cleaning position, the pinion 53 attached to the motor 52 meshes with the rack 51 provided on the lower surface of the outer nozzle 30 so that the cleaning nozzle moves. The outer nozzle 30 and the inner nozzle 40 are moved together by the latch mechanism 60 that connects the outer nozzle 30 and the inner nozzle 40. Thereby, since the positional relationship between the outer nozzle 30 and the inner nozzle 40 is not shifted, the vehicle can move forward while maintaining a normal cleaning range. Further, the normal cleaning position is determined by being coaxial with the center of the first cleaning port 31 a and the protrusion 41 of the inner nozzle 40 being locked to the first locking portion 21 a of the main body 20.

  FIG. 3 (c) shows the adjustment (maximum position) from normal cleaning to extensive cleaning. In order to perform a wide range of cleaning from normal cleaning, the cleaning nozzle is advanced by the drive mechanism 50 from the state of FIG. At this time, the inner nozzle 40 cannot move because the protrusion 41 is locked to the first locking portion 21a. Thereby, since only the outer nozzle 30 moves forward, the second cleaning port 31b closed by the inner nozzle 40 can be opened to discharge the fluid, and a wide range of cleaning is possible.

  FIG. 3D shows a cleaning position in the case of wide-area cleaning. Although the cleaning range can be widened in FIG. 3C, only the outer nozzle 30 moves forward, so the cleaning position of the cleaning port 31 composed of the first cleaning port 31a and the second cleaning port 31b (of the cleaning portion). (Center) will shift. For this reason, the drive mechanism 50 adjusts the position by moving the cleaning nozzle backward so that the center positions of the first cleaning port 31a and the second cleaning port 31b reach the cleaning position. At this time, since the outer nozzle 30 and the inner nozzle 40 are moved backward together by the latch mechanism 60, the cleaning nozzle can move to the cleaning position while maintaining a wide cleaning range.

  FIG. 3E shows a state before the cleaning nozzle is completely stored. After a wide range of cleaning, the drive mechanism 50 moves the cleaning nozzle back to the storage position. At this time, the outer nozzle 30 and the inner nozzle 40 are integrally moved backward by the latch mechanism 60, but the protrusion 41 of the inner nozzle 40 slides so that the inner nozzle 40 reaches the storage position before the outer nozzle 30. It is locked to the second locking portion 21b of the moving part.

  FIG. 3F shows a state where the cleaning nozzle is housed. After the inner nozzle 40 is locked, the cleaning mechanism 31 is closed by the sliding member 42 of the inner nozzle 40 by retracting only the outer nozzle 30 by the driving mechanism 50. Thereby, the outer nozzle 30 and the inner nozzle 40 are accommodated in a state in which the cleaning port 31 can be normally cleaned.

  In the present embodiment, the first cavity portion and the second cavity portion of the cavity portion 32 are configured to have different volumes. Therefore, during normal cleaning, the first cleaning of the first cavity portion having a smaller volume than the second cavity portion is performed. The water pressure of the cleaning water discharged from the mouth can be secured sufficiently, and when washing over a wide area, the volume of the cleaning water can be increased even if the water pressure decreases due to the increased volume. Comfortable cleaning can be provided.

  Next, a sealing member 70 that seals with the cavity 32 and the sliding member 42 according to the embodiment of the present invention will be described with reference to FIG. FIG. 4 is an explanatory diagram of the seal member 70 between the cavity 32 and the sliding member 42 shown in FIG. 3, and (a) this embodiment, (b) modification 1, (c) modification 2, (D) Modification 3 is shown.

Furthermore, by forming the first seal member 71 and the second seal member 72 integrally, the number of parts can be reduced. Further, when the sealing member 70 is attached to the sliding member 42, the sliding member 42 is covered without being required to have a structure (such as a groove or a hole for attaching the sealing member 70). It becomes possible. Further, since the sealing member 70 covers the sliding member 42, the force applied from both the axial direction and the radial direction is dispersed, so that durability against abrasion due to sliding can be improved.

As shown in FIG. 4C, in the second modification, an O-ring-shaped first seal member 271 is provided on the first inner wall 34a side and the second inner wall 34b side of the second cavity portion 32b. In addition, the first seal member 71 can be positioned by making the first seal member 71 come into contact with at least two points facing the inner circumference in the radial direction of the second cavity portion 32b. Furthermore, if the O-ring-shaped first seal member 271 has a diameter wider than the outer circumference in the radial direction of the first cavity portion 32a, the gap generated in the inner wall 34 and the sliding member 42 can be filled by elastic deformation. Become.

(Modification 3)
4D, in the third modification, the first seal member 371 that seals the axial direction so as to contact the first inner wall 34a and the second inner wall 34b is embedded on both sides of the sliding member 42 in the axial direction. Is provided. Since the first seal member 371 provided on the sliding member 42 abuts against the inner wall 34, the first seal member 371 can be filled with a gap generated in the inner wall 34 and the sliding member 42 due to elastic deformation. Become.

  In the first to third modifications, the second sealing member 72 that seals the radial direction may be worn by the sliding of the second cavity portion 32b and the sliding member 42. In order to limit the cleaning range without fine adjustment of the second cleaning port 31b possible in the embodiment, only the first seal member 71 of the axial seal is provided. However, in the first to third modifications, the second seal member 72 can be provided on the sliding member 42. Therefore, when the second seal member 72 is provided, the second cavity 32b and the sliding member 42 can be sealed in the axial direction and the radial direction, so the second cleaning port 31b having a plurality of discharge ports can be finely formed. Adjustment is possible.
