Abstract

PROBLEM TO BE SOLVED: To provide a sanitary washing device which can be miniaturized particularly in a height direction.SOLUTION: A sanitary washing device comprises: a washing nozzle which has a discharge port and washes a body of a user by spraying water through the discharging port; and a casing capable of storing the washing nozzle. The washing nozzle shifts from a storage state where the washing nozzle is stored in the casing to an advanced state where the washing nozzle is positioned to wash the body while changing a posture in a manner that increases an angle of an axis of the washing nozzle with a horizontal plane.

Description

  Aspects of the present invention generally relate to a sanitary washing apparatus, and more specifically, to a sanitary washing apparatus for washing a user's “butt” or the like seated on a Western-style seated toilet with water.

  In the sanitary washing apparatus, a washing nozzle for washing a body such as a “butt” of a user sitting on a toilet seat, a drive unit for driving the washing nozzle, and the like are housed in a casing, for example. When the water is sprayed onto the user's “buttock” or the like, the washing nozzle moves linearly while maintaining the stored angle, and advances from the casing into the bowl of the toilet bowl. Further, the cleaning nozzle is generally housed in the casing at a predetermined angle that is the same as the angle at which the cleaning nozzle is advanced so as not to come into contact with the user's buttocks when the cleaning nozzle is advanced into the bowl of the toilet bowl. Here, with the recent improvement in the design of the toilet space, it is desired to make the sanitary washing device compact.

  For example, there is a human body local cleaning device that can change the angle of the cleaning nozzle (Patent Document 1). In the human body local cleaning device described in Patent Document 1, the cleaning nozzle moves linearly as viewed from the cylinder. The cylinder is provided so as to be rotatable as viewed from the base member. However, the cylinder is present on the base member regardless of whether the cleaning nozzle is in the advanced state that is in use or in the retracted state. Therefore, even if the angle of the cleaning nozzle can be changed, a space for the cylinder to rotate on the base member, particularly a space above the casing is required. In addition, even when the angle of the cylinder and the cleaning nozzle with respect to the base member is kept small when the cleaning nozzle is in the retracted state, when the cleaning nozzle is advanced, it is necessary to set the angle so as not to contact the user's buttocks. is there. Therefore, a problem remains in that the height when the cleaning nozzle is stored is suppressed and the human body local cleaning device is made compact.

  In addition, the drying nozzle is in a tilted position with the tip with the blowout port facing downward at the retreat position, and the drying nozzle advances from the position of the blowout port when the drying nozzle is advanced in the longitudinal direction in the inclined position. There is a human body drying device that is controlled by a nozzle drive unit so that the position of the air outlet in the position is positioned upward (Patent Document 2). However, in the human body drying apparatus described in Patent Document 2, the drying nozzle is in a standing state in the retracted position rather than the advanced position. Therefore, a problem remains in that the height when the drying nozzle is retracted is suppressed and the human body drying apparatus is made compact.

  According to this sanitary washing apparatus, the washing nozzle changes from the housed state to the advanced state while changing to a posture in which the angle of the axis of the washing nozzle with respect to the horizontal plane is increased. Therefore, the cleaning nozzle can be accommodated in a posture in which the angle of the axis of the cleaning nozzle with respect to the horizontal plane is smaller than the advanced state, and the rotation necessary for changing the angle by moving the cleaning nozzle while changing the angle. Space can be minimized. Thereby, the height of the cleaning nozzle in the housed state can be further reduced. For this reason, the height of the sanitary washing device can be kept lower, and the sanitary washing device can be made compact.

  Further, according to a second aspect of the present invention, in the first aspect, the angle of the storage state is determined by the user when the cleaning nozzle has advanced in the storage state at the angle in the storage state. The sanitary washing apparatus is characterized in that the angle of contact with the buttock and the washing nozzle can avoid contact with the buttock of the user by advancing while transitioning to a posture in which the angle increases. .

  According to this sanitary cleaning device, the cleaning nozzle can avoid contact with the user's buttocks by moving forward to a posture in which the angle of the axis of the cleaning nozzle with respect to the horizontal plane is increased. Therefore, the cleaning nozzle can be stored in a posture in which the angle of the axis of the cleaning nozzle with respect to the horizontal plane is small enough to come into contact with the user's buttock when the cleaning nozzle advances in the stored state (angle). . Thereby, even when the height of the cleaning nozzle in the housed state is kept lower, it is possible to avoid the cleaning nozzle in the advanced state from coming into contact with the user's buttocks.

  According to this sanitary washing device, the tip of the washing nozzle draws a curved track after drawing a straight track. Therefore, when the tip of the cleaning nozzle draws a curved track, the distance between the rear end of the cleaning nozzle and the casing is the same as when the curved nozzle is drawn before the tip of the cleaning nozzle draws a straight track. Long compared. Therefore, the tip of the cleaning nozzle can draw a larger curved trajectory. Thereby, the height of the cleaning nozzle in the housed state can be further reduced. Therefore, the height of the sanitary washing apparatus can be further reduced, and the sanitary washing apparatus can be further downsized.

  According to a fifth aspect of the present invention, in the third or fourth aspect of the invention, the length of the linear track is longer than the length of the curved track.

  According to this sanitary washing device, it is possible to avoid contact between the cleaning nozzle and the user's buttocks in a straight track longer than the curved track. Therefore, a wider cleaning range can be ensured. Thereby, a move function can be performed, stabilizing a feeling of washing in a wider range.

  In addition, when a curved orbit is drawn after the front end portion of the cleaning nozzle draws a linear trajectory, a longer distance is secured between the rear end portion of the cleaning nozzle and the casing by drawing the linear trajectory. be able to. Therefore, a larger space can be secured when the tip of the cleaning nozzle draws a curved path. Therefore, the height of the sanitary washing apparatus can be further reduced, and the sanitary washing apparatus can be further downsized.

The sanitary washing device is characterized by changing from the stored state to the advanced state.

  According to this sanitary washing device, the trajectory of the cleaning nozzle is regulated by the trajectory guide. Therefore, the cleaning nozzle changes from the housed state to the advanced state while drawing substantially the same trajectory each time. Thereby, the movement of the cleaning nozzle and the reliability of the sanitary cleaning device can be further enhanced.

  According to a seventh aspect of the present invention, in the sixth aspect of the invention, the trajectory guide includes an angle restricting portion that restricts an angle of the linear trajectory with respect to the horizontal plane.

  According to this sanitary washing device, the angle of the straight track with respect to the horizontal plane is regulated by the angle regulating unit. Therefore, the angle of the straight track with respect to the horizontal plane does not change every time the cleaning nozzle moves. Therefore, it is not necessary to adjust the cleaning nozzle to a preferred position every time the user uses the sanitary cleaning device. Thereby, the usability of the sanitary washing device can be further improved.

  According to an eighth aspect of the present invention, in the sixth or seventh aspect, the track guide has a track groove that regulates the track of the cleaning nozzle, and the cleaning nozzle can be fitted into the track groove. The sanitary washing apparatus is characterized in that it has a joint part, and the fitting part moves along the fixed track by moving while sliding on the track groove.

  According to this sanitary washing device, the raceway guide is formed with a raceway groove, and the cleaning nozzle has a fitting portion that can be fitted into the raceway groove. And the fitting part is fitted by the track groove. Therefore, it is possible to prevent the cleaning nozzle from moving in a stable manner and advance the cleaning nozzle stably. Thereby, the movement of the cleaning nozzle and the reliability of the sanitary cleaning device can be further enhanced.

The sanitary washing device 100 includes a casing 400, a toilet seat 200, and a toilet lid 300. The toilet seat 200 and the toilet lid 300 are pivotally supported with respect to the casing 400 so as to be freely opened and closed.

  Inside the casing 400 is incorporated a body washing function unit that implements washing of a user who sits on the toilet seat 200 such as a “butt”. Further, for example, the casing 400 is provided with a seating detection sensor 404 that detects that the user has sat on the toilet seat 200. When the seating detection sensor 404 detects a user sitting on the toilet seat 200, when the user operates an operation unit (not shown) such as a remote controller, the cleaning nozzle 473 can be advanced into the bowl 801 of the toilet 800. it can. In the sanitary washing apparatus 100 shown in FIG. 1, the washing nozzle 473 has entered the bowl 801.

  One or a plurality of water discharge ports 474 are provided at the tip of the cleaning nozzle 473. Then, the washing nozzle 473 can wash water such as a “butt” of a user sitting on the toilet seat 200 by ejecting water from a water discharge port 474 provided at the tip of the washing nozzle 473. In the present specification, the term “water” includes not only cold water but also warm hot water.

FIG. 2 is a schematic perspective view illustrating the nozzle unit of this embodiment.
2A is a schematic perspective view showing a state in which the cleaning nozzle is housed in the casing, and FIG. 2B is a schematic perspective view showing a state in which the cleaning nozzle has advanced.

  As shown in FIG. 2, the nozzle unit 470 of this embodiment includes a base 475, a cleaning nozzle 473 supported by the base 475, and a nozzle motor 476 that moves the cleaning nozzle 473. The cleaning nozzle 473 includes a nozzle head 471 and a cylinder 472. That is, the cleaning nozzle 473 shown in FIG. 2 is a two-stage type. In this embodiment, a two-stage type, that is, a cleaning nozzle having two movable parts will be described as an example. However, the present invention is not limited to this, and the multi-stage type cleaning nozzle has three or more movable parts. And a single-stage cleaning nozzle whose movable part is only a nozzle head.

  The nozzle head 471 is slidable with respect to the cylinder 472, and at least a part of the nozzle head 471 can be stored in the cylinder 472. The nozzle head 471 is slidable with respect to the base 475 by the driving force transmitted from the nozzle motor 476. This will be described in detail later.

The nozzle motor 476 is fixed to the base 475.
Further, the cleaning nozzle 473 includes a slider 477. The cylinder 472 is fixed to the slider 477. The slider 477 is provided slidably with respect to the base 475. Therefore, the cylinder 472 can slide with respect to the base 475 together with the slider 477. Accordingly, the cleaning nozzle 473 can move forward and backward from the casing 400 and the base 475.

  The casing 400 is provided with a trajectory guide 450 that guides the movement of the cleaning nozzle 473. The cleaning nozzle 473 draws a fixed trajectory by the trajectory guide 450 and changes from the stored state to the advanced state. At this time, the cleaning nozzle 473 advances while changing to a posture in which the angle θ (see FIG. 4) of the shaft 473c of the cleaning nozzle 473 with respect to a horizontal plane 850 (see FIG. 4) such as the upper surface of the toilet 800 is increased. In other words, the cleaning nozzle 473 advances while making a transition to a posture in which the cleaning nozzle 473 stands up from the stored state. This will be described in detail with reference to the drawings.

FIG. 3 is a schematic plan view illustrating the trajectory of the cleaning nozzle of this embodiment.
4 and 5 are schematic plan views showing the nozzle unit of the present embodiment.
FIG. 6 is a schematic cross-sectional view showing the nozzle unit of the present embodiment.
3 to 5 are schematic plan views of the nozzle unit 470 of the present embodiment as viewed from the right side. FIG. 6 is a schematic cross-sectional view of a cut surface along the axis 473c of the cleaning nozzle 473, that is, a cut surface AA shown in FIG. Furthermore, in the nozzle unit 470 shown in FIG. 5, the nozzle motor 476 is omitted for convenience of explanation.

  As shown in FIGS. 4 to 6, the casing 400 includes a case plate 401 and a case cover 402. The body washing function unit and the like are appropriately placed on the case plate 401 and the upper part thereof is covered with the case cover 402.

  A cable rack 478 is fixed to the nozzle head 471 as shown in FIG. The cable rack 478 is formed of a material such as a flexible resin. At least one side surface of the cable rack 478 is provided with irregularities that engage with the gears 481 and 483. The cable rack 478 is slidable in the sanitary washing device 100 along the first cable guide portion 479 provided on the base 475 and the second cable guide portion 411 provided on the casing 400. It is supported by.

  The nozzle motor 476 can reduce the drive output appropriately and output it to the gears 481 and 483. The cable rack 478 is engaged with the gear 483 and converts the rotational driving force of the gear 483 into a linear driving force to move the nozzle head 471. That is, the nozzle head 471 is slidably provided with respect to the base 475 by the driving force transmitted from the nozzle motor 476 via the gears 481 and 483 and the cable rack 478.

  As shown in FIGS. 3 to 5, the track guide 450 is formed with a track groove 451 that regulates the track of the cleaning nozzle 473. On the other hand, as shown in FIGS. 3 and 5, the slider 477 is provided with a fitting portion 477 b that can be fitted into the raceway groove 451. The fitting portion 477b is fitted in the raceway groove 451. When the cleaning nozzle 473 changes from the housed state to the advanced state, the fitting portion 477b of the slider 477 moves while sliding on the track groove 451. Therefore, the slider 477 moves following a substantially same track as the track groove 451.

  The fitting portion 477b may be attached to the slider 477 as, for example, a non-rotatable protrusion, or may have a portion that is rotatable with respect to the slider 477. In the case where the fitting portion 477 b has a portion that is rotatable with respect to the slider 477, the fitting portion 477 b of the slider 477 moves while rotating the track groove 451. Therefore, the range of “sliding” in the present specification includes not only the case of sliding in the contact state but also the case of rolling in the contact state.

  The trajectory guide 450 includes a curve restriction part 453 and a straight line restriction part (angle restriction part) 455. The curve restricting portion 453 is formed in a substantially horizontal direction. On the other hand, the straight line restricting portion 455 is formed to be inclined so that one end portion on the side connected to the curve restricting portion 453 is higher than the other end portion on the side not connected to the curve restricting portion 453. In other words, the straight line restricting portion 455 is formed to be inclined so that the other end portion on the side not connected to the curve restricting portion 453 is lower than the one end portion on the side connected to the curve restricting portion 453. Note that the straight line regulating portion 455 may be provided with a lock mechanism, or a drive source for changing the angle may be provided.

  First, when the cleaning nozzle 473 starts to change from the housed state to the advanced state, the fitting portion 477b of the slider 477 slides on the curve restricting portion 453. At this time, as shown in FIG. 2, the cylinder 472 passes through the cylindrical body 461 that is pivotally supported with respect to the casing 400 by the rotation shaft 463. The cylindrical body 461 is formed in a cylindrical shape, and can rotate about the rotation shaft 463 according to the angle of the cylinder 472. The cylindrical body 461 and the rotation shaft 463 can guide and regulate the movement of the cleaning nozzle 473.

  Therefore, when the cleaning nozzle 473 starts to change from the housed state to the advanced state, the fitting portion 477b is guided by the curve restriction portion 453 and moves in a substantially horizontal direction. On the other hand, the cylinder 472 passes through the inside of the cylindrical body 461 that rotates about the rotation shaft 463. Accordingly, the cleaning nozzle 473 moves forward while making a transition to a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 is increased. In other words, the cleaning nozzle 473 advances while making a transition to a posture in which the cleaning nozzle 473 stands up from the stored state. Therefore, when the fitting portion 477b of the slider 477 slides on the curve restricting portion 453, the tip end portion of the cleaning nozzle 473 (tip end portion of the nozzle head 471) 473a is curved track 491 as shown in FIG. Advance while drawing.

  Subsequently, the fitting portion 477 b of the slider 477 slides on the straight line regulating portion 455. At this time, since the cylindrical body 461 is pivotally supported with respect to the casing 400, the inclination angle of the linear restricting portion 455, that is, the moving direction of the slider 477 and the cylinder 472, the axial direction of the cylindrical body 461, Are substantially the same. Thereby, when the fitting part 477b of the slider 477 slides on the straight line restricting part 455, the tip part 473a of the cleaning nozzle 473 advances while drawing a straight track 493 as shown in FIG.

When the cleaning nozzle 473 advances, the base 475 and the nozzle motor 476 are displaced in conjunction with the advancement of the cleaning nozzle 473 as shown in FIGS. Therefore, the relative position between the base 475 and the nozzle motor 476 does not change depending on the advance of the cleaning nozzle 473.
The advance order of the nozzle head 471 and the cylinder 472 is not particularly limited. For example, in a state where the nozzle head 471 is stored in the cylinder 472, the tip portion 473a of the cleaning nozzle 473 advances while drawing a curved track 491. Thereafter, the nozzle head 471 slides out of the cylinder 472, and the tip portion 473a of the cleaning nozzle 473 advances while drawing a straight track 493. In this case, the tip 473a of the cleaning nozzle 473 advances while drawing a curved track 491 in a state where the multistage cleaning nozzle 473 is made more compact. Thereby, the height of the cleaning nozzle 473 in the housed state can be kept lower. Therefore, the height of the sanitary washing apparatus 100 can be suppressed to be lower, and the sanitary washing apparatus 100 can be made compact.
Alternatively, for example, the operation in which the tip portion 473a of the cleaning nozzle 473 advances while drawing the curved track 491 and the operation in which the nozzle head 471 slides out of the cylinder 472 may be performed in parallel.

  According to the present embodiment, the cleaning nozzle 473 advances while changing to a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 is increased. Therefore, the cleaning nozzle 473 can be accommodated in a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 is smaller than the advanced state. Further, the rotation space required for changing the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 can be minimized. Thereby, the height of the cleaning nozzle 473 in the housed state can be kept lower. Therefore, the height of the sanitary washing apparatus 100 can be suppressed to be lower, and the sanitary washing apparatus 100 can be made compact.

  Further, as shown in FIG. 3, the linear trajectory 493 corresponds to the last portion in the trajectory of the tip portion 473 a of the cleaning nozzle 473. In other words, the tip 473a of the cleaning nozzle 473 draws a straight track 493 after the curved track 491. Therefore, for example, even when a user uses a function (move function) that can adjust the position of the cleaning nozzle 473, the water discharge range of the cleaning water sprayed from the cleaning nozzle 473 does not change. Therefore, the feeling of cleaning with the cleaning water sprayed from the cleaning nozzle 473 can be stabilized. In addition, the front-end | tip part 473a of the washing | cleaning nozzle 473 may draw the linear track | orbit 493, may draw the curve track | orbit 491 after that, and may draw the linear track | orbit 493 finally. That is, in the present embodiment, the linear track 493 only needs to correspond to the last part of the track of the tip portion 473a of the cleaning nozzle 473.

Further, as shown in FIG. 3, the length of the straight track 493 is longer than the length of the curved track 491. Therefore, a wider cleaning range can be ensured. Thereby, the sanitary washing apparatus 100 concerning this embodiment can perform a move function, stabilizing a washing | cleaning feeling in a wider range.
In addition, the angle of the straight track 493 with respect to the horizontal plane 850 is regulated by the inclination angle of the straight regulation unit 455. Therefore, the angle of the straight track 493 with respect to the horizontal plane 850 does not change every time the cleaning nozzle 473 moves. Therefore, it is not necessary to adjust the cleaning nozzle 473 to a preferred position every time the user uses the sanitary cleaning device 100. Thereby, the usability of the sanitary washing device 100 according to the present embodiment can be further improved.

  Further, the track of the cleaning nozzle 473 is regulated by the track guide 450. Therefore, the cleaning nozzle 473 changes from the housed state to the advanced state while drawing substantially the same trajectory each time. In this embodiment, the track guide 450 is formed with a track groove 451, and the fitting portion 477 b is fitted into the track groove 451. For this reason, it is possible to prevent the cleaning nozzle 473 from moving in a stable manner and prevent the cleaning nozzle 473 from moving forward. Thereby, the movement of the cleaning nozzle 473 and the reliability of the sanitary cleaning device 100 can be further improved.

  As shown in FIG. 5, the fitting portion 477 b is provided on the rear end side of the cleaning nozzle 473. The track guide 450 is disposed and fixed in the casing 400. That is, the trajectory guide 450 does not move with the cleaning nozzle 473. Therefore, the track of the cleaning nozzle 473 shown in FIG. 3 can be formed by a member or structure provided inside the casing 400. Thereby, the height of the cleaning nozzle 473 in the housed state can be suppressed to a lower level with a simpler structure. Therefore, the height of the sanitary washing apparatus 100 can be suppressed to be lower, and the sanitary washing apparatus 100 can be made compact.

  Further, as described above, the nozzle motor 476 is fixed to the base 475 and is displaced in conjunction with the advance of the cleaning nozzle 473. Therefore, the amount of change in the angle of the nozzle motor 476 relative to the horizontal plane 850 is the same as the amount of change in the angle θ of the shaft 473c of the cleaning nozzle 473 relative to the horizontal plane 850. In other words, the base 475 and the nozzle motor 476 move while drawing the same trajectory. Therefore, the driving force transmitted from the nozzle motor 476 to the nozzle head 471 is kept substantially constant. That is, the cleaning nozzle 473 can advance with a substantially constant driving force transmitted from the nozzle motor 476. Alternatively, the relationship between the rotation angle of the nozzle motor 476 and the advance amount of the cleaning nozzle 473 is linear. Thereby, the washing nozzle 473 can be advanced stably. Further, when the user adjusts the position of the cleaning nozzle 473, the cleaning nozzle 473 can be accurately moved to a predetermined position.

  Further, the slider 477 advances and draws substantially the same track as the track groove 451 formed in the track guide 450. Therefore, when the fitting portion 477b slides on the curve restricting portion 453, the upper end portion 477a of the slider 477, as shown in FIG. Advance while drawing 495. Therefore, the cleaning nozzle 473 can advance while making a transition to a standing posture from the storage state by using the space B (see FIGS. 4 to 6) existing above the cleaning nozzle 473 in the storage state by a forward operation. Therefore, there is no need for a special space for the cleaning nozzle 473 to transition to a posture in which the cleaning nozzle 473 stands up from the stored state. Thereby, the height of the case cover 402 can be kept lower. Therefore, the height of the sanitary washing apparatus 100 can be suppressed to be lower, and the sanitary washing apparatus 100 can be made compact.

FIG. 7 is a schematic plan view illustrating the positional relationship between the cleaning nozzle in the housed state and the user's buttocks seated on the toilet seat.
FIG. 8 is a schematic plan view illustrating the positional relationship between the cleaning nozzle in the advanced state and the user's buttocks seated on the toilet seat.
FIG. 9 is a schematic plan view illustrating the positional relationship between the cleaning nozzle in the middle of advancing and the user's buttocks seated on the toilet seat.

  As described above with reference to FIGS. 3 to 6, in this embodiment, the cleaning nozzle 473 can be accommodated in a posture in which the angle θ of the shaft 473 c of the cleaning nozzle 473 with respect to the horizontal plane 850 is smaller than the advanced state. More specifically, as shown in FIG. 7, the shaft 473 c of the cleaning nozzle 473 in the housed state interferes with the user's buttocks 600 seated on the toilet seat 200. In other words, the angle θ with respect to the horizontal plane 850 of the shaft 473c of the cleaning nozzle 473 in the storage state is in contact with the buttocks 600 of the user seated on the toilet seat 200 when the cleaning nozzle 473 has advanced in the storage state (angle). It is an angle to do.

In contrast, as shown in FIG. 9, the cleaning nozzle 473 of the present embodiment advances while shifting to a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 becomes large. Therefore, as shown in FIG. 8, the shaft 473 c of the cleaning nozzle 473 in the advanced state does not interfere with the user's buttocks 600 seated on the toilet seat 200. As shown in FIGS. 8 and 9, the advancing state and the advancing cleaning nozzle 473 do not come into contact with the user's buttocks 600 seated on the toilet seat 200. In the present embodiment, the curved track 491 drawn by the tip 473a of the cleaning nozzle 473 is a track that avoids the cleaning nozzle 473 from contacting the user's buttocks 600 seated on the toilet seat 200. On the other hand, a straight track 493 drawn by the tip 473a of the cleaning nozzle 473 is a track that reaches the advanced state. Accordingly, the cleaning nozzle 473 is moved in a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 is small to the extent that the shaft 473c of the cleaning nozzle 473 in the stored state interferes with the user's buttocks 600 seated on the toilet seat 200. Can be stored. In addition, the transition from the curved track 491 to the straight track 493 at the timing when the tip 473a of the cleaning nozzle 473 arrives at the tip of the rear of the toilet seat 200 prevents interference between the cleaning nozzle 473 and the user's buttocks 600. It can be surely prevented.
Note that the angle θ for avoiding the interference between the cleaning nozzle 473 and the user's buttocks 600 is determined by the toilet seat 200 and the toilet bowl 800 having a general shape, and the general storage position (for example, the horizontal direction and the vertical direction with respect to the buttocks 600). In the case of using the sanitary washing device 100 having the washing nozzle 473 installed at a relative position of, for example, about 30 ° to 45 °.

  According to the present embodiment, even when the height of the cleaning nozzle 473 in the housed state is kept lower, it is avoided that the cleaning nozzle 473 in the advanced state and during the advancement comes into contact with the user's buttocks 600 seated on the toilet seat 200. it can. Thereby, the height of the cleaning nozzle 473 in the housed state can be kept lower. Therefore, the height of the sanitary washing apparatus 100 can be suppressed to be lower, and the sanitary washing apparatus 100 can be made compact.

  Further, according to the present embodiment, when the distal end portion 473a of the cleaning nozzle 473 advances while drawing the linear track 493, the cleaning nozzle 473 is prevented from coming into contact with the user's buttocks 600. Therefore, a wider cleaning range can be ensured. Thereby, the sanitary washing apparatus 100 concerning this embodiment can perform a move function, stabilizing a washing | cleaning feeling in a wider range.

Next, another embodiment of the present invention will be described.
FIG. 10 is a schematic plan view showing a nozzle unit according to another embodiment of the present invention.
In the nozzle unit 470a shown in FIG. 10, the nozzle motor 476 is omitted for convenience of explanation.

  The cleaning nozzle 473 of this embodiment is a single-stage cleaning nozzle whose movable part is only a nozzle head. The cleaning nozzle 473 is fixed to the slider 477. Other structures are the same as those of the nozzle unit 470 described above with reference to FIGS.

  First, when the cleaning nozzle 473 starts to change from the housed state to the advanced state, the fitting portion 477b of the slider 477 slides on the curve restricting portion 453. At this time, the cleaning nozzle 473 passes through the cylindrical body 461 that is pivotally supported with respect to the casing 400 by the rotation shaft 463. The cylindrical body 461 is formed in a cylindrical shape, and can rotate around the rotation shaft 463 according to the angle of the cleaning nozzle 473.

  Therefore, when the cleaning nozzle 473 starts to change from the housed state to the advanced state, the fitting portion 477b is guided by the curve restriction portion 453 and moves in a substantially horizontal direction. On the other hand, the cleaning nozzle 473 passes through the inside of the cylindrical body 461 that rotates about the rotation shaft 463. Accordingly, as illustrated in FIG. 10, the cleaning nozzle 473 advances while changing to a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 is increased. In other words, the cleaning nozzle 473 advances while making a transition to a posture in which the cleaning nozzle 473 stands up from the stored state. Therefore, when the fitting portion 477b of the slider 477 slides on the curve restricting portion 453, the tip portion 473a of the cleaning nozzle 473 advances while drawing a curved track 491 (see FIG. 3).

  Subsequently, the fitting portion 477 b of the slider 477 slides on the straight line regulating portion 455. At this time, since the cylindrical body 461 is pivotally supported with respect to the casing 400, the inclination angle of the linear restriction portion 455, that is, the moving direction of the slider 477 and the cleaning nozzle 473, and the axial direction of the cylindrical body 461. Are substantially the same. Thereby, when the fitting part 477b of the slider 477 slides on the straight line restricting part 455, the tip part 473a of the cleaning nozzle 473 advances while drawing a straight track 493 (see FIG. 3).

  According to this embodiment, even when the cleaning nozzle 473 is not a multi-stage type but a single-stage type, the cleaning nozzle 473 moves forward while making a transition to a posture in which the angle θ of the axis 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 becomes large. Therefore, the cleaning nozzle 473 can be accommodated in a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 is smaller than the advanced state. Further, the rotation space required for changing the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 can be minimized. Thereby, the height of the cleaning nozzle 473 in the housed state can be kept lower. Therefore, the height of the sanitary washing apparatus 100 can be suppressed to be lower, and the sanitary washing apparatus 100 can be made compact. Further, with respect to other effects, the same effects as those described above with reference to FIGS.

Next, still another embodiment of the present invention will be described.
FIG. 11 is a schematic plan view showing a nozzle unit according to still another embodiment of the present invention. In the nozzle unit 470b shown in FIG. 11, the nozzle motor 476 is omitted for convenience of explanation.

  The structure of the nozzle unit 470b shown in FIG. 11 is the same as the structure of the nozzle unit 470 described above with reference to FIGS. In this embodiment, the advance order of the nozzle head 471 and the cylinder 472 is different from the advance order of the nozzle head 471 and the cylinder 472 in the nozzle unit 470 described above with reference to FIGS.

  As shown in FIG. 11A and FIG. 11B, first, the nozzle head 471 slides out of the cylinder 472 with the slider 477 and the cylinder 472 stopped, and the inside of the cylinder 461 Pass through. At this time, since the nozzle head 471 slides inside the cylinder 472 and passes through the inside of the cylindrical body 461, the distal end portion 473a of the cleaning nozzle 473 advances while drawing a linear track 493 (see, for example, FIG. 3).

  Subsequently, as illustrated in FIG. 11C, the fitting portion 477 b of the slider 477 slides on the curve restriction portion 453. At this time, as described above with reference to FIGS. 3 to 6, the cleaning nozzle 473 advances while changing to a posture in which the angle θ of the shaft 473 c of the cleaning nozzle 473 with respect to the horizontal plane 850 becomes large. In other words, the cleaning nozzle 473 advances while making a transition to a posture in which the cleaning nozzle 473 stands up from the stored state. Therefore, the tip 473a of the cleaning nozzle 473 advances while drawing a curved track 491 (see, for example, FIG. 3).

  Subsequently, as illustrated in FIG. 11D, the fitting portion 477 b of the slider 477 slides on the linear restriction portion 455. At this time, as described above with reference to FIGS. 3 to 6, since the cylindrical body 461 is pivotally supported with respect to the casing 400, the inclination angle of the linear regulating portion 455, that is, the movement of the slider 477 and the cylinder 472. The direction and the axial direction of the cylinder 461 are substantially the same. Thereby, the front-end | tip part 473a of the washing nozzle 473 advances, drawing the linear track 493.

  As described above, the tip 473a of the cleaning nozzle 473 of the present embodiment draws a linear trajectory 493, then draws a curved trajectory 491, and finally draws a linear trajectory 493. In the present embodiment, when the nozzle head slides out of the cylinder 472 with the slider 477 and the cylinder 472 stopped, the linear track 493 drawn by the tip portion 473a of the cleaning nozzle 473 indicates that the cleaning nozzle 473 is a toilet seat. This is a trajectory approaching and advancing to the user's buttocks 600 seated on 200. Further, the curved track 491 drawn by the tip 473a of the cleaning nozzle 473 is a track that avoids the cleaning nozzle 473 from contacting the user's buttocks 600 seated on the toilet seat 200. Further, when the fitting portion 477b of the slider 477 slides on the straight line regulating portion 455, the straight track 493 (the last straight track 493) drawn by the tip portion 473a of the cleaning nozzle 473 is a track that reaches the advanced state. .

  According to this embodiment, since the cylinder 472 first moves after the nozzle head 471 has advanced, the operation of the multistage cleaning nozzle and the body cleaning of the multistage cleaning nozzle (the outer peripheral surfaces of the nozzle head 471 and the cylinder 472) In consideration of cleaning of the water discharge port 474 and the like, the configuration or structure of the nozzle unit 470b can be further simplified. Further, since the linear track 493 corresponds to the last part of the track of the tip portion 473a of the cleaning nozzle 473, as described above, even when the move function is used, the cleaning feeling of the cleaning water sprayed from the cleaning nozzle 473 is felt. It can be stabilized.

  Further, similarly to the operation of the cleaning nozzle 473 shown in FIG. 5, the cleaning nozzle 473 advances while changing to a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 becomes large. Therefore, the height of the sanitary washing apparatus 100 can be suppressed to be lower, and the sanitary washing apparatus 100 can be made compact.

Next, still another embodiment of the present invention will be described.
FIG. 12 is a schematic plan view showing a nozzle unit according to still another embodiment of the present invention. In the nozzle unit 470c shown in FIG. 12, the nozzle motor 476 is omitted for convenience of explanation.

  The track guide 450 provided in the casing 400 of the present embodiment is formed with a track groove 451 a that regulates the track of the cleaning nozzle 473. The trajectory guide 450a includes a curve restriction part 453a and a straight line restriction part (angle restriction part) 455a.

  The curve restricting portion 453a is formed in a substantially horizontal direction. On the other hand, the straight line restricting portion 455a is formed to be inclined so that one end portion on the side connected to the curve restricting portion 453a is lower than the other end portion on the side not connected to the curve restricting portion 453a. In other words, the straight line restricting portion 455a is formed to be inclined so that the other end portion on the side not connected to the curve restricting portion 453a is higher than the one end portion on the side connected to the curve restricting portion 453a.

  In other words, in the present embodiment, the arrangement relationship between the straight line restriction portion 455a and the curve restriction portion 453a is different from the arrangement relationship between the straight line restriction portion 455 and the curve restriction portion 453 described above with reference to FIGS. In the raceway groove 451 described above with reference to FIGS. 2 to 11, when the cleaning nozzle 473 advances, the fitting portion 477 b of the slider 477 first slides on the curve restriction portion 453 and then slides on the linear restriction portion 455. Move. On the other hand, in this embodiment, when the cleaning nozzle 473 advances, the fitting portion 477b of the slider 477 first slides on the straight line regulating portion 455a, and then slides on the curve regulating portion 453a.

  The other structure of the nozzle unit 470c is the same as the structure of the nozzle unit 470 described above with reference to FIGS. Note that the straight line regulating portion 455a may be provided with a lock mechanism, or a drive source for changing the angle may be provided.

  First, when the cleaning nozzle 473 starts to change from the housed state to the advanced state, as shown in FIGS. 12A and 12B, the fitting portion 477b of the slider 477 slides on the linear regulating portion 455a. To do. At this time, since the cylindrical body 461 is pivotally supported with respect to the casing 400, the inclination angle of the linear restriction portion 455a, that is, the moving direction of the slider 477 and the cylinder 472, the axial direction of the cylindrical body 461, Are substantially the same. Thereby, when the fitting part 477b of the slider 477 slides on the straight line restricting part 455a, the tip part 473a of the cleaning nozzle 473 advances while drawing a straight track 493 (see, for example, FIG. 3).

  Subsequently, the fitting portion 477b of the slider 477 slides on the curve restriction portion 453a. At this time, the cylinder 472 passes through the cylindrical body 461 that is pivotally supported with respect to the casing 400 by the rotation shaft 463. As described above, the cylindrical body 461 is formed in a cylindrical shape and can rotate around the rotation shaft 463 according to the angle of the cylinder 472. The cylindrical body 461 and the rotation shaft 463 can guide and regulate the movement of the cleaning nozzle 473.

  Therefore, the fitting part 477b is guided by the curve restriction part 453a and moves in a substantially horizontal direction. On the other hand, the cylinder 472 passes through the inside of the cylindrical body 461 that rotates about the rotation shaft 463. Accordingly, the cleaning nozzle 473 moves forward while making a transition to a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 is increased. In other words, the cleaning nozzle 473 advances while making a transition to a posture in which the cleaning nozzle 473 stands up from the stored state. Therefore, when the fitting part 477b of the slider 477 slides on the curve restriction part 453, the tip part 473a of the cleaning nozzle 473 advances while drawing a curved track 491 (see, for example, FIG. 3).

  As described above, the tip 473a of the cleaning nozzle 473 of the present embodiment draws a linear trajectory 493 and then a curved trajectory 491. In the present embodiment, the straight track 493 drawn by the tip 473a of the cleaning nozzle 473 is a track in which the cleaning nozzle 473 approaches and advances toward the user's buttocks 600 seated on the toilet seat 200. On the other hand, the curved trajectory 491 drawn by the tip 473a of the cleaning nozzle 473 is a trajectory that avoids the cleaning nozzle 473 coming into contact with the user's buttocks 600 seated on the toilet seat 200 and reaches the advanced state. That is, the curved track 491 corresponds to the last part of the locus of the tip portion 473a of the cleaning nozzle 473.

  According to the present embodiment, the tip 473a of the cleaning nozzle 473 draws a curved track 491 after drawing a straight track 493. Therefore, when the front end 473a of the cleaning nozzle 473 draws the curved track 491, the distance between the rear end of the cleaning nozzle 473 or the upper end 477a of the slider 477 and the casing 400 is the front end of the cleaning nozzle 473. This is longer than the case where the curved track 491 is drawn before the straight track 493 is drawn. Therefore, the tip portion 473a of the cleaning nozzle 473 can draw a larger curved track. Thereby, the height of the cleaning nozzle 473 in the housed state can be further reduced. Therefore, the height of the sanitary washing apparatus 100 can be further reduced, and the sanitary washing apparatus 100 can be further downsized.

  As shown in FIG. 12, the length of the straight line restricting portion 455a is longer than the length of the curved line restricting portion 453a. Therefore, the length of the straight track 493 is longer than the length of the curved track 491. As a result, the tip 473a of the cleaning nozzle 473 draws a straight track 493, so that a longer distance can be secured between the rear end of the cleaning nozzle 473 or the upper end 477a of the slider 477 and the casing 400. it can. Therefore, a larger space can be secured when the tip portion 473a of the cleaning nozzle 473 draws the curved track 491. Therefore, the height of the sanitary washing apparatus 100 can be further reduced, and the sanitary washing apparatus 100 can be further downsized.

  The case where the cleaning nozzle 473 changes from the housed state to the advanced state has been mainly described above. However, the cleaning nozzle 473 moves while drawing a similar trajectory when changing from the advanced state to the stored state. That is, for example, when the cleaning nozzle 473 changes from the advanced state to the housed state, the distal end portion 473a of the cleaning nozzle 473 draws a curved track 491 after the straight track 493. Or the front-end | tip part 473a of the washing nozzle 473 draws the linear track | orbit 493, draws the curved track | orbit 491 after that, and draws the linear track | orbit 493 finally. Or the front-end | tip part 473a of the washing nozzle 473 draws the linear track 493 after drawing the curved track 491. That is, the cleaning nozzle 473 moves backward while transitioning to a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 becomes small. The cleaning nozzle 473 is accommodated in a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 is smaller than the advanced state.
