JP, 2016-056566, A

  However, in the local cleaning unit as described above, there is room for improvement in terms of the complexity of the structure of the support having the guide rails and the rack guides.

  The present invention has been made in view of these circumstances, and an object thereof is to provide a local cleaning unit which can suppress the complication of the structure for guiding the nozzle and the flexible rack.

  A local cleaning unit for solving the above problems comprises a nozzle capable of ejecting liquid, a nozzle guide for guiding the forward and backward movement of the nozzle, a flexible rack connected to the nozzle, and a drive gear for driving the flexible rack. And a driving unit, and the nozzle guide guides the flexible rack.

  According to the above configuration, since the nozzle guide guides the nozzle and the flexible rack, it is possible to suppress the complication of the structure for guiding the nozzle and the flexible rack.

  Further, in the local cleaning unit, the nozzle has a protrusion that protrudes in the width direction, and the nozzle guide faces the protrusion in the vertical direction intersecting with the axial direction of the drive gear so as to face the protrusion Preferably, the flexible rack is connected to the proximal end of the protrusion of the nozzle.

  According to the above configuration, since the projecting portion is guided by being opposed to the rail in the vertical direction intersecting the axial direction of the drive gear, the nozzle guide guides the forward and backward movement of the nozzle. In addition, when the flexible rack is driven, a force is applied to the flexible rack to vertically bend in a direction intersecting with the axial direction of the drive gear. At this time, the protrusion protrudes in the width direction of the nozzle, and the flexible rack is connected to the base end of the protrusion. Therefore, when the nozzle moves back and forth, the flexible rack is positioned between the rails in the vertical direction intersecting the axial direction of the drive gear. Therefore, the nozzle guide guides the flexible rack because the rail regulates the vertical movement of the nozzle guide. Thus, since the nozzle guide guides the nozzle and the flexible rack, it is possible to suppress the complication of the structure for guiding the nozzle and the flexible rack.

  Further, in the local cleaning unit, the rail has a side wall sandwiching the projecting portion in the width direction of the nozzle, and an inner wall guiding the flexible rack together with the side wall in the width direction, and the nozzle It has a groove through which the inner wall is slidably inserted.

  According to the above configuration, since the flexible rack is guided by the side wall and the inner wall in the width direction, it is possible to suppress the bending in the width direction of the flexible rack.

  The local cleaning unit further includes a center plate having the nozzle guide and a hose connecting the nozzle and a liquid supply source, and the hose is disposed on one side of the center plate in the width direction. Preferably, the flexible rack is disposed on the other side of the center plate.

  According to the above configuration, the hose and the flexible rack do not interfere with each other by arranging the hose and the flexible rack with the center plate interposed therebetween. For this reason, it can arrange so that a hose and a flexible rack may overlap, seeing from the cross direction. Therefore, the height of the local cleaning unit can be reduced.

  As shown in FIGS. 2 and 3, the local cleaning unit 1 includes a center plate 10 forming a base portion, a nozzle 20 capable of ejecting liquid, a hose 40 for supplying liquid to the nozzle 20, and the nozzle 20. Flexible rack 50 to move forward and backward, flow rate adjustment valve 60 (an example of liquid supply source) for supplying liquid to hose 40, drive unit 70 for moving flexible rack 50, and side for fixing drive unit 70 to center plate 10 And a plate 80.

  In the following description, the width direction of the local cleaning unit 1 is also referred to as "width direction X", the height direction of the local cleaning unit 1 is also referred to as "height direction Y", and both in the width direction X and height direction Y The orthogonal direction is also referred to as "longitudinal direction Z". Further, one end in the width direction X is referred to as “first end X1”, and the other end in the width direction X is referred to as “second end X2”.

  As shown in FIG. 4, the center plate 10 includes a standing plate 11 extending in a direction intersecting (orthogonal to) the width direction X, a guide 12 provided at the rear end of the standing plate 11, And a nozzle guide 30 provided at the upper end. An opening 110 for disposing the flow rate adjustment valve 60 is formed in the lower portion of the standing plate 11.

  As shown in FIG. 3, the guides 12 are provided on both sides in the width direction X of the standing plate 11. That is, the guide 12 is extended toward the first end X1 and the second end X2 so as to be orthogonal to the standing plate 11. The guide 12 is provided so as to move vertically upward while curving toward the rear. The guide 12 extending toward the first end X1 is referred to as a first guide 121, and the guide 12 extending toward the second end X2 is referred to as a second guide 122.

  As shown in FIGS. 4 and 5, the nozzle guide 30 has a cylindrical portion 31 having a cylindrical shape, and a long rail 33. In the nozzle guide 30, the cylindrical portion 31 is provided at the tip of the standing plate 11. The rails 33 are provided in such a manner as to move vertically downward as they go forward, in a state where they are provided on the standing plate 11. The rail 33 has a bottom wall 34 sliding with the nozzle 20, a side wall 35 and a regulating wall 36. The bottom wall 34 is provided at the upper end of the standing plate 11. The bottom wall 34 extends outward in the width direction X so as to be orthogonal to the standing plate 11. The bottom wall 34 has a plate shape. The side walls 35 are erected vertically upward from both ends of the bottom wall 34 in the width direction X. Then, the restriction wall 36 extends inward in the width direction X from the upper end of the side wall 35. That is, the bottom wall 34 and the restriction wall 36 are spaced apart in the height direction Y.

  As shown in FIG. 5 and FIG. 6, the nozzle 20 has a main body 22 and a protrusion 21. The main body portion 22 has a substantially cylindrical shape. The main body portion 22 has an injection port (not shown) at its tip. A hose 40 is connected to the proximal end of the main body 22. Then, the liquid supplied from the hose 40, for example, the washing water, is injected from the injection port of the main body 22 through the flow path provided inside the main body 22.

  The protrusion 21 is provided at a position near the base end of the main body 22. The protrusion 21 protrudes in the direction orthogonal to the longitudinal direction of the main body 22. That is, the protrusion 21 protrudes from the main body 22 toward the first end X1 and the second end X2. The cross-sectional shape of the protrusion 21 in the longitudinal direction of the nozzle 20 is substantially the same as the cross-sectional shape of the space surrounded by the bottom wall 34, the side wall 35 and the restriction wall 36 in the longitudinal direction of the rail 33.

  The nozzle 20 is supported movably relative to the nozzle guide 30. That is, the main body 22 of the nozzle 20 is disposed so as to be accommodated in the cylindrical portion 31 of the nozzle guide 30, and the projection 21 of the nozzle 20 is accommodated in the space surrounded by the bottom wall 34, the side wall 35 and the regulation wall 36 of the rail 33. Arranged as. Thus, the nozzle 20 is supported movably in the longitudinal direction of the nozzle 20 with respect to the nozzle guide 30. When the nozzle 20 moves relative to the nozzle guide 30, the main body 22 of the nozzle 20 slides on the cylindrical portion 31 of the nozzle guide 30, and the protrusion 21 of the nozzle 20 is the bottom wall 34 of the nozzle guide 30, the side wall 35 and It slides on the regulation wall 36.

  As shown in FIG. 5, the hose 40 is disposed on the second end X2 side of the center plate 10. The hose 40 is a supply pipe for supplying washing water to the nozzle 20. The hose 40 may be made of a deformable material, for example, preferably made of a rubber material. The downstream end of the hose 40 is connected to the proximal end of the nozzle 20, and the upstream end of the hose 40 is connected to the flow control valve 60.

  As shown in FIG. 3, the flexible rack 50 is an elastically deformable rack having teeth 51. The flexible rack 50 may be made of, for example, a resin. The flexible rack 50 is disposed on the first end X1 side of the center plate 10 in a curved manner such that the teeth 51 face inward. The flexible rack 50 is connected to the proximal end of the protrusion 21 of the nozzle 20. The flexible rack 50 may be connected to the nozzle 20, for example, by being pressed into a hole formed at the proximal end of the protrusion 21 of the nozzle 20.

  As shown in FIGS. 2 and 5, the flow rate adjustment valve 60 has a substantially cylindrical shape. The flow rate adjustment valve 60 is fixed to the center plate 10 in a state of passing through an opening 110 provided in the standing plate 11 of the center plate 10. The flow rate adjustment valve 60 adjusts the flow rate when the wash water flowing from a water supply or the like is supplied to the hose 40.

  As shown in FIG. 3, the drive unit 70 has a drive gear 72 that meshes with the teeth 51 of the flexible rack 50 and a drive source 71 that rotates the drive gear 72. The drive source 71 is, for example, a motor.

  The drive gear 72 rotates by receiving the rotation of the output shaft of the drive source 71 from a gear provided on the output shaft. At this time, the drive gear 72 meshes with the teeth 51 of the flexible rack 50 to configure a mechanism for converting the rotational movement of the output shaft of the drive unit 70 into the linear movement of the nozzle 20. That is, the drive unit 70 is configured to move the nozzle 20 back and forth.

  The side plate 80 is fixed to the first end X1 side of the center plate 10. The drive source 71 of the drive unit 70 is fixed to the side of the first end X1 of the side plate 80. Further, the side plate 80 is formed with an insertion hole 81 through which the drive gear 72 of the drive unit 70 is inserted. The drive gear 72 inserted into the insertion hole 81 is disposed between the center plate 10 and the side plate 80. At this time, since the flexible rack 50 is disposed so as to mesh with the drive gear 72, the flexible rack 50 is disposed between the center plate 10 and the side plate 80. Therefore, the side plate 80 restricts the movement of the flexible rack 50 in the width direction X together with the center plate 10.

  The side plate 80 also has a curved portion 82 extending inward in the width direction X. The curved portion 82 is curved in a substantially arc shape as viewed from the width direction X from the rear end of the rail 33 toward the upper side of the opening 110. Therefore, the flexible rack 50 extending rearward from the rail 33 curves downward of the center plate 10 along the curved portion 82.

  Further, the flexible rack 50 is disposed between the bending portion 82 and the drive gear 72 in the direction orthogonal to the rotation axis of the drive gear 72. Therefore, the flexible rack 50 is less likely to be separated from the drive gear 72 in the direction orthogonal to the rotation axis of the drive gear 72. Therefore, the force when driving the drive gear 72 is transmitted to the flexible rack 50 without escape.

  Next, the operation of the local cleaning unit 1 will be described.

  As shown in FIGS. 7 and 8, when the human body local portion is cleaned by the local portion cleaning unit 1, the flexible rack 50 advances by rotating the drive source 71 in the forward direction. At this time, the protrusion 21 of the nozzle 20 is sandwiched by the rail 33 of the nozzle guide 30 in the width direction X and the height direction Y. For this reason, the nozzle 20 advances along the nozzle guide 30 by the protrusion 21 sliding on the rail 33. Thus, the nozzle guide 30 guides the advancing movement of the nozzle 20.

  In addition, when the nozzle 20 advances, a load that compresses the flexible rack 50 acts to bend the flexible rack 50. At this time, since the flexible rack 50 is connected to the base end of the projecting portion 21, between the rails 33 (the bottom wall 34 and the restriction wall 36 in the vertical direction in which the flexible rack 50 intersects with the axial direction of the drive gear 72). Located between). Therefore, the movement of the flexible rack 50 in the vertical direction intersecting the axial direction of the drive gear 72 is restricted. That is, since the flexible rack 50 is less likely to bend, the force for advancing the nozzle 20 is less likely to be lost. As a result, the nozzle 20 can travel along the nozzle guide 30.

  Thereafter, when the cleaning of the human body part by the part cleaning unit 1 is completed, the flexible rack 50 is retracted by reversing the driving source 71. At this time, the nozzle guide 30 guides the retreat of the nozzle 20 by the rail 33 as in the case of the movement of the nozzle 20 in the advancing direction. In addition, the nozzle guide 30 guides the flexible rack 50 in the backward direction of the nozzle 20 in the same manner as when the nozzle 20 moves in the forward direction. Thus, the nozzle guide 30 guides the advancing and retracting movement of the nozzle 20 and guides the flexible rack 50 in the advancing and retracting direction of the nozzle 20. In addition, since a pulling force acts on the flexible rack 50 when the nozzle 20 retracts, bending of the flexible rack 50 is suppressed.

  According to the embodiment described above, the following effects can be obtained.

  (1) Since the nozzle guide 30 guides the nozzle 20 and the flexible rack 50, the structure for guiding the nozzle 20 and the flexible rack 50 can be prevented from being complicated.

  (2) Since the flexible rack 50 is connected to the base end of the projecting portion 21, the flexible rack 50 can be positioned between the rails 33 in the vertical direction intersecting the axial direction of the drive gear 72 when the nozzle 20 moves back and forth . Therefore, the nozzle guide 30 guides the flexible rack 50 because the rail 33 regulates the vertical movement of the nozzle guide 30. Thus, since the nozzle guide 30 guides the nozzle 20 and the flexible rack 50, it is possible to suppress the complication of the structure for guiding the nozzle 20 and the flexible rack 50.

  (3) By arranging the hose 40 and the flexible rack 50 with the center plate 10 interposed therebetween, the hose 40 and the flexible rack 50 do not interfere with each other. Therefore, when viewed from the width direction X, the hose 40 and the flexible rack 50 can be arranged to overlap. Therefore, the height of the local cleaning unit 1 can be reduced.

  Below, another embodiment of the embodiment mentioned above is described.

  -As shown in FIG. 9, the rail 33 may have the inner wall 37 which stands vertically upward from the position away from the both ends in the width direction X of the bottom wall 34. As shown in FIG. The inner wall 37 is provided over substantially the entire length of the bottom wall 34 in the longitudinal direction. The inner wall 37 is provided to sandwich the flexible rack 50 between the side wall 35 and the inner wall 37 in the width direction X when the nozzle 20 is disposed on the rail 33. Further, below the nozzle 20, a groove 23 is recessed in the longitudinal direction of the nozzle 20. The groove 23 is provided to slide on the inner wall 37 when the nozzle 20 moves back and forth.

  When the nozzle 20 disposed on the rail 33 travels, a load that compresses the flexible rack 50 acts to bend the flexible rack 50. At this time, the flexible rack 50 may try to bend in the width direction X. At this time, since the flexible rack 50 is sandwiched between the side wall 35 and the inner wall 37, the bending of the flexible rack 50 in the width direction X can be suppressed.

  -The shape of the rail 33 and the protrusion part 21 should just correspond mutually. For example, when the cylindrical portion 31 is provided over substantially the entire length of the nozzle 20, a groove-shaped rail 33 corresponding to the protrusion 21 may be formed on the inner periphery of the cylindrical portion 31. The rails 33 and the protrusions 21 may not be provided on both sides in the width direction X. For example, the rail 33 and the protrusion 21 may be provided on one side in the width direction X, or may be provided in the height direction Y.

  In addition, when the rail 33 has a cylindrical shape, the nozzle 20 may not have the protrusion 21. At this time, the flexible rack 50 may be connected to the proximal end of the nozzle 20. That is, the flexible rack 50 may not be connected to the proximal end of the protrusion 21. According to this, the nozzle 20 is guided by the rail 33. Further, since the flexible rack 50 is regulated by the rail 33 in the direction orthogonal to the advancing direction of the nozzle 20, the flexible rack 50 is guided by the nozzle guide 30 in the advancing direction of the nozzle 20. Thus, the nozzle guide 30 guides the flexible rack 50 and the nozzle 20.

  The hose 40 and the flexible rack 50 may be arranged on one side of the center plate 10. According to this, the nozzle 20 can be miniaturized in the width direction X.
