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 shown in FIG. 2 is a single-stage type, that is, a cleaning nozzle having one movable part, but the present invention is not limited to this. The cleaning nozzle may be a multistage cleaning nozzle having a plurality of movable parts.

  The cleaning nozzle 473 is slidable with respect to the base 475 by a driving force transmitted from the nozzle motor 476. The nozzle motor 476 is fixed to the base 475.

  Further, the cleaning nozzle 473 includes a slider 477. The slider 477 is provided slidably with respect to the base 475. Therefore, the cleaning nozzle 473 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 includes a case plate 401 and a case cover 402. A shutter 420 that opens and closes the opening of the case cover 402 is provided on the front side of the case cover 402. As shown in FIG. 2B, the shutter 420 can be opened and closed as the cleaning nozzle 473 advances and retreats. More specifically, the shutter 420 is pivotally supported with respect to the case cover 402. When the cleaning nozzle 473 advances from the casing 400, the shutter 420 can rotate about the upper portion to open the opening of the case cover 402. On the other hand, the shutter 420 can rotate around the upper part to close the opening of the case cover 402 when or after the cleaning nozzle 473 is retracted to the casing 400. In addition, the installation form of the shutter 420 is not limited to this, For example, you may pivotally support to the case plate 401, for example.

  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 transitions to a posture where the angle θ (see FIG. 4A) of the shaft 473c of the cleaning nozzle 473 with respect to a horizontal plane 850 (see FIG. 4A) such as the upper surface of the toilet 800 becomes large. To advance. 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.
FIG. 4 is a schematic plan view of the nozzle unit of this embodiment as viewed from the right side.

  A cable rack 478 (see FIGS. 6 to 14) is fixed to the cleaning nozzle 473. 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 (see FIGS. 6 to 14). 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 cleaning nozzle 473. That is, the cleaning nozzle 473 is slidable 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 and 4, 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 4, 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 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, 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. That is, the angle of the cylinder 461 with respect to the casing 400 changes in conjunction with the change in the angle of the cleaning nozzle 473. 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 cleaning nozzle 473 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 portion 473a of the cleaning nozzle 473 advances while drawing a curved track 491 as shown in FIG.

  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 as shown in FIG.

  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 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. Therefore, the shaft 473c of the cleaning nozzle 473 in the advanced state does not interfere with the user's buttocks seated on the toilet seat 200. Further, the advancing state and the cleaning nozzle 473 during the advancing are not in contact with the buttocks of the user seated on the toilet seat 200. Accordingly, the cleaning nozzle 473 is stored in a posture in which the angle θ with respect to the horizontal plane 850 of the shaft 473c of the cleaning nozzle 473 is small to the extent that the shaft 473c of the cleaning nozzle 473 in the stored state interferes with the buttocks of the user seated on the toilet seat 200. Can be made.

  Note that the angle θ for avoiding the interference between the cleaning nozzle 473 and the user's buttocks depends on the toilet seat 200 and the toilet bowl 800 having a general shape, and the general storage position (for example, relative to the buttocks in the horizontal and vertical directions). When the sanitary washing apparatus 100 having the washing nozzle 473 installed at the target position is used, for example, it is about 30 ° to 45 °.

  According to the present embodiment, as shown in FIGS. 3 and 4A to 4E, the cleaning nozzle 473 transitions to a posture in which the angle θ of the shaft 473c of the cleaning nozzle 473 with respect to the horizontal plane 850 increases. While moving forward. Further, even when the height of the cleaning nozzle 473 in the housed state is suppressed to be lower, it is possible to avoid the cleaning nozzle 473 in the advanced state and in the middle of the advancement coming into contact with the buttocks of the user seated on the toilet seat 200. Furthermore, 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.

  The sanitary washing device 100 according to the present embodiment includes a nozzle cleaning unit that cleans or cleans the cleaning nozzle 473. When the cleaning nozzle 473 is changed from the housed state to the advanced state, the nozzle cleaning unit discharges cleaning water from the water discharging unit to the appearance surface (side surface or body surface) of the cleaning nozzle 473, Appearance surface can be cleaned. Alternatively, when the cleaning nozzle 473 is changed from the advanced state to the housed state, the nozzle cleaning unit discharges cleaning water to the external surface of the cleaning nozzle 473 and cleans the external surface of the cleaning nozzle 473. it can. Alternatively, the nozzle cleaning unit may apply the cleaning nozzle 473 to the appearance surface of the cleaning nozzle 473 when the cleaning nozzle 473 is changed from the retracted state to the advanced state and when the cleaning nozzle 473 is changed from the advanced state to the retracted state. The cleaning water can be discharged to clean the external surface of the cleaning nozzle 473.

  As described above, 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. That is, the cleaning nozzle 473 advances from the casing 400 or moves back to the casing 400 with a change in angle. Therefore, when the nozzle cleaning unit simply discharges the cleaning water, the distance between the water discharging unit of the nozzle cleaning unit and the appearance surface of the cleaning nozzle 473 changes. Therefore, the cleaning nozzle 473 may have uneven cleaning or uncleaned appearance, and the cleaning nozzle 473 may not be kept hygienic. In addition, since the manner in which the cleaning water hits the external surface of the cleaning nozzle 473 changes as the distance between the water discharge portion of the nozzle cleaning unit and the external surface of the cleaning nozzle 473 changes, the range and direction of the cleaning water splash Varies greatly depending on the state of the cleaning nozzle 473. For this reason, a large-scale structure is required in consideration of taking measures against scattering.

  On the other hand, in the sanitary washing device 100 according to the present embodiment, the distance L between the water discharge portion of the nozzle washing portion and the external surface of the washing nozzle 473 is, for example, as indicated by an arrow A shown in FIG. It is constant when the nozzle 473 is changing from the stored state to the advanced state and when the nozzle 473 is changing from the advanced state to the stored state. Note that the arrow A shown in FIG. 3 is for convenience of explanation, and the water discharge portion of the nozzle cleaning unit is at one end of the arrow A shown in FIG. 3 (one end opposite to the appearance surface of the cleaning nozzle 473). It does not mean changing while drawing such a trajectory.

  According to this, even if the cleaning nozzle 473 advances and retreats with an angle change, the cleaning water is discharged from the nozzle cleaning unit at a constant distance with respect to the appearance surface of the cleaning nozzle 473. Therefore, it is possible to suppress the occurrence of uneven washing or unwashed residue due to the difference in the cleaning position on the external surface of the cleaning nozzle 473, and to maintain the external surface of the cleaning nozzle 473 in a sanitary manner. In addition, since the manner in which the cleaning water hits the external surface of the cleaning nozzle 473 is constant, the range and direction in which the cleaning water scatters does not change depending on the state of the cleaning nozzle 473. For this reason, it is possible to take measures with a simple structure in consideration of taking measures against scattering.

  In addition, the nozzle cleaning unit of the present embodiment starts to discharge the cleaning water when the tip 473a of the cleaning nozzle 473 advances after the second half of the curved track 491. Therefore, it is not necessary to adjust the distance L between the water discharge part of the nozzle cleaning part and the appearance surface of the cleaning nozzle 473 to be larger. Thereby, the distance L between the water discharging part of the nozzle cleaning part and the appearance surface of the cleaning nozzle 473 can be made more stable at a constant distance, and the cleaning water can be discharged from the nozzle cleaning part. In addition, for example, the nozzle cleaning unit starts discharging the cleaning water when the distal end portion 473a of the cleaning nozzle 473 advances into the linear track 493. When the distal end portion 473a of the cleaning nozzle 473 draws the linear track 493, the cleaning nozzle 473 advances without changing the angle. Therefore, when the tip portion 473a of the cleaning nozzle 473 is drawing the linear track 493, it is not necessary to adjust the distance L between the water discharge portion of the nozzle cleaning portion and the appearance surface of the cleaning nozzle 473. Thereby, the distance L between the water discharging part of the nozzle cleaning part and the appearance surface of the cleaning nozzle 473 can be further stabilized at a constant distance, and the cleaning water can be discharged from the nozzle cleaning part.

Next, a specific example of the nozzle cleaning unit will be described with reference to the drawings.
FIG. 5 is a schematic perspective view illustrating a specific example of the nozzle cleaning unit of the present embodiment.
6 to 9 are schematic cross-sectional views for explaining the operation of the nozzle cleaning unit of this example.
6 to 9 are schematic cross-sectional views taken along a cutting plane AA shown in FIG. 2A, that is, a cutting plane along the axis 473 c of the cleaning nozzle 473.
Moreover, FIG.7 (b) is an expansion schematic diagram of the area | region B represented to Fig.7 (a), FIG.8 (b) is an expansion schematic diagram of the area | region C represented to Fig.8 (a).
Further, in FIG. 5, the trajectory guide 450, the cylindrical body 461, and the like are omitted for convenience of explanation.

  As shown in FIG. 5, the nozzle cleaning unit 510 of this specific example is provided in a shutter (interlocking member) 420. As described above with reference to FIG. 2, the shutter 420 can be interlocked with the change from the housed state of the cleaning nozzle 473 to the advanced state and the change from the advanced state to the accommodated state. The nozzle cleaning unit 510 includes a water discharge unit 515 that discharges cleaning water to the external surface of the cleaning nozzle 473, and a rib (distance regulating member) 511 that keeps the water discharge unit 515 and the external surface of the cleaning nozzle 473 constant. Have. The distance regulating member may be provided in at least one of the shutter 420 and the nozzle cleaning unit 510.

  As illustrated in FIG. 6A, the shutter 420 closes the opening of the case cover 402 in a state where the cleaning nozzle 473 is housed in the casing 400. At this time, the rib 511 of the nozzle cleaning unit 510 and the external surface of the cleaning nozzle 473 are not in contact with each other. Subsequently, as illustrated in FIG. 6B, when the cleaning nozzle 473 starts to change from the housed state to the advanced state, it contacts the shutter 420 and presses the shutter 420. Then, the shutter 420 rotates around the upper part in conjunction with the advance / retreat change of the cleaning nozzle 473. Also at this time, the rib 511 of the nozzle cleaning unit 510 and the appearance surface of the cleaning nozzle 473 are not in contact with each other.

  Subsequently, as shown in FIG. 7A, when the cleaning nozzle 473 further advances, the shutter 420 further rotates. As shown in FIG. 7B, the rib 511 of the nozzle cleaning unit 510 is in contact with the external surface of the cleaning nozzle 473. In a state where the rib 511 is in contact with the external surface of the cleaning nozzle 473, the nozzle cleaning unit 510 can discharge the cleaning water from the water discharge unit 515 and clean the external surface of the cleaning nozzle 473.

  Subsequently, as illustrated in FIG. 8A, the cleaning nozzle 473 further advances. At this time, the rib 511 and the external surface of the cleaning nozzle 473 are in contact with each other. That is, the cleaning nozzle 473 advances with the rib 511 and the external surface of the cleaning nozzle 473 in contact with each other. Therefore, as shown in FIG. 7B and FIG. 8B, the distance L between the water discharge unit 515 of the nozzle cleaning unit 510 and the external surface of the cleaning nozzle 473 is set so that the cleaning nozzle 473 advances from the housed state. It is constant when changing to a state.

  Subsequently, as illustrated in FIG. 9, the cleaning nozzle 473 advances to a predetermined cleaning position in a state where the rib 511 and the external surface of the cleaning nozzle 473 are in contact with each other. Also at this time, the distance L between the water discharger 515 of the nozzle cleaning unit 510 and the appearance surface of the cleaning nozzle 473 is constant. Then, the cleaning nozzle 473 can spray water from the water outlet 474 to clean the “butt” of the user sitting on the toilet seat 200.

  According to this specific example, even if the cleaning nozzle 473 advances and retreats with an angle change, the cleaning water is discharged from the nozzle cleaning unit 510 at a constant distance with respect to the appearance surface of the cleaning nozzle 473. Therefore, it is possible to suppress the occurrence of uneven washing or unwashed residue due to the difference in the cleaning position on the external surface of the cleaning nozzle 473, and to maintain the external surface of the cleaning nozzle 473 in a sanitary manner. In addition, since the manner in which the cleaning water hits the external surface of the cleaning nozzle 473 is constant, the range and direction in which the cleaning water scatters does not change depending on the state of the cleaning nozzle 473. For this reason, it is possible to take measures with a simple structure in consideration of taking measures against scattering.

  In addition, the nozzle cleaning unit 510 of this specific example is provided in the shutter 420 that is interlocked with the advance / retreat change of the cleaning nozzle 473. Therefore, it is not necessary to form the nozzle cleaning unit 510 separately and interlock it with the advance / retreat change of the cleaning nozzle 473. Specifically, for example, there is no need to provide a motor, a gear, or the like that causes the nozzle cleaning unit 510 to be interlocked with the advance / retreat change of the cleaning nozzle 473. Therefore, the sanitary washing device 100 can be made compact.

  In addition, the nozzle cleaning unit 510 of this specific example includes a rib 511 that keeps the water discharge unit 515 and the appearance surface of the cleaning nozzle 473 constant. Therefore, it is not necessary to control the position of the water discharger 515 by a control unit (not shown). In other words, by utilizing the self-weight of the nozzle cleaning unit 510, the distance L between the water discharge unit 515 of the nozzle cleaning unit 510 and the external surface of the cleaning nozzle 473 can be kept constant. Thereby, the distance L between the water discharge part 515 of the nozzle washing | cleaning part 510 and the external appearance surface of the washing nozzle 473 can be kept constant with a simpler structure.

  In addition, since the nozzle cleaning unit 510 of this specific example is provided in the shutter 420 disposed in front of the cleaning nozzle 473 in the housed state, not only the external appearance surface of the central portion of the cleaning nozzle 473 but also the external appearance of the tip portion. The surface can be cleaned. Thereby, it is not necessary to store the washing nozzle 473 in the back (rear) of the casing 400, and the sanitary washing apparatus 100 can be made compact in the front-rear direction.

  More specifically, a cable rack 478 is fixed to the nozzle head 471. 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.

  The advancement order of the nozzle head 471 and the cylinder 472 is, for example, as follows. As shown in FIGS. 10A and 10B, the tip 473a of the cleaning nozzle 473 advances while drawing a curved track 491 in a state where the nozzle head 471 is stored in the cylinder 472.

As shown in FIGS. 10A and 10B, the rib 521 of the nozzle cleaning unit 520 is in contact with the external surface of the nozzle head 471. In a state where the rib 521 is in contact with the external surface of the nozzle head 471, the nozzle cleaning unit 520 can discharge the cleaning water from the water discharge unit 525 and clean the external surface of the nozzle head 471.

  Subsequently, as shown in FIGS. 11A and 11B, the nozzle head 471 further slides out of the cylinder 472. At this time, the rib 521 and the external surface of the nozzle head 471 are in contact with each other. That is, the nozzle head 471 slides out of the cylinder 472 with the rib 521 and the external surface of the nozzle head 471 in contact with each other. Therefore, as shown in FIG. 10B and FIG. 11B, the distance L between the water discharge unit 525 of the nozzle cleaning unit 520 and the external surface of the nozzle head 471 is such that the nozzle head 471 is in the cylinder 472. It is constant when sliding out from the outside.

  Subsequently, as illustrated in FIG. 12, the nozzle head 471 advances to a predetermined position in a state where the rib 521 and the external surface of the nozzle head 471 are in contact with each other. Also at this time, the distance L between the water discharger 525 of the nozzle cleaning unit 520 and the external surface of the nozzle head 471 is constant.

  Subsequently, as illustrated in FIG. 13A, when the cylinder 472 is pulled by the nozzle head 471, the distal end portion 473 a of the cleaning nozzle 473 further advances while drawing a linear track 493. At this time, as shown in FIG. 13B, the rib 521 of the nozzle cleaning unit 520 runs from the external surface of the nozzle head 471 to the external surface of the cylinder 472. The rib 521 of the nozzle cleaning unit 520 is in contact with the external surface of the cylinder 472. In a state where the rib 521 is in contact with the external surface of the cylinder 472, the nozzle cleaning unit 520 can discharge the cleaning water from the water discharge unit 525 and clean the external surface of the cylinder 472.

  As shown in FIG. 14A and FIG. 14B, the cylinder 472 is pulled by the nozzle head 471 and further advances. At this time, the rib 521 and the external surface of the cylinder 472 are in contact with each other. That is, the cylinder 472 advances with the rib 521 and the external surface of the cylinder 472 in contact with each other. Therefore, as shown in FIGS. 13B and 14B, the distance L between the water discharge unit 525 of the nozzle cleaning unit 520 and the external surface of the cylinder 472 is such that the cylinder 472 is pulled by the nozzle head 471. It is constant when advancing.

The distance L can be kept constant. Therefore, even if the multistage cleaning nozzle 473 advances and retreats with a change in angle, the cleaning water is discharged from the nozzle cleaning unit 520 at a constant distance with respect to the appearance surface of the cleaning nozzle 473. For this reason, it is possible to suppress the occurrence of uneven washing or unwashed residue due to the difference in the cleaning position on the external surface of the multistage cleaning nozzle 473, and to maintain the external surface of the multistage cleaning nozzle 473 in a sanitary manner. In addition, since the manner in which the washing water hits the external surface of the multi-stage washing nozzle 473 is constant, the range and direction in which the washing water scatters does not change depending on the state of the washing nozzle 473. For this reason, it is possible to take measures with a simple structure in consideration of taking measures against scattering.
