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.
  On the other hand, the drying nozzle is set in a tilted posture in which the tip portion with the blowout port is directed downward at the retracted position, and is dried more than the position of the blowout port when the drying nozzle is advanced in the longitudinal direction while being in the tilted posture. There is a human body drying device that is controlled by a nozzle drive unit so that the position of the blowout port at the nozzle advance position is positioned upward (Patent Document 2). In the human body drying apparatus described in Patent Document 2, the inclination of the drying nozzle changes as the drying nozzle advances. However, since the drive unit is located in the main body case and connected to the motor by a shaft, the driving force transmitted from the drive unit to the drying nozzle may change when the inclination angle of the drying nozzle changes. If it does so, there exists a possibility that a dry nozzle may not advance stably without advancing with a fixed advance amount. Thereby, for example, even when the user adjusts the position of the drying nozzle, the position of the drying nozzle may be deviated from a desired position. Furthermore, 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.

  The present invention has been made on the basis of recognition of such a problem, and provides a sanitary washing device capable of stably moving a washing nozzle or moving a washing nozzle to a washing position accurately. With the goal.
  A first invention has a water discharge port, a cleaning nozzle that sprays water from the water discharge port to clean a user's body, a casing that can store the cleaning nozzle, and a cleaning nozzle that moves forward and backward from the casing. And a transmission unit that transmits the driving force of the driving unit to the cleaning nozzle, and the angle of the shaft of the cleaning nozzle with respect to the horizontal plane is greater than the advanced state in which the cleaning nozzle has advanced from the casing. The cleaning nozzle is small in the storage state housed in the casing, and the cleaning nozzle changes from the storage state to the advance state while transitioning to a posture in which the angle increases, and the pushing amount of the driving unit and the advance amount of the cleaning nozzle The sanitary washing apparatus is characterized by being linear.
  According to this sanitary washing device, even if the cleaning nozzle changes from the housed state to the advanced state while the angle of the axis of the cleaning nozzle with respect to the horizontal plane increases, the drive unit push-out amount and the cleaning nozzle advance amount The relationship between and is kept linear. That is, the driving force transmitted from the driving unit to the transmission unit does not cause a loss when the cleaning nozzle moves forward while shifting to a posture in which the cleaning nozzle stands up from the housed state. Therefore, the cleaning nozzle can advance with a constant driving force transmitted from the driving unit. Thereby, a washing nozzle can be advanced stably. Further, when the user adjusts the position of the cleaning nozzle, the cleaning nozzle can be accurately moved to a predetermined position. Here, “linear” means that the relationship between the push-out amount of the drive unit and the advancement amount of the cleaning nozzle is expressed by a linear expression.
  According to a second aspect of the present invention, in the first aspect of the present invention, the drive unit is displaced in conjunction with the movement of the cleaning nozzle.
  According to this sanitary washing device, the position of the drive unit is interlocked with the movement of the washing nozzle even if the washing nozzle changes from the housed state to the advanced state while the angle of the axis of the washing nozzle with respect to the horizontal plane is increased. And change. Therefore, the relationship between the push-out amount of the drive unit and the advance amount of the cleaning nozzle can be kept linear. Thereby, a washing nozzle can be advanced stably. Further, when the user adjusts the position of the cleaning nozzle, the cleaning nozzle can be accurately moved to a predetermined position.

A sanitary washing device characterized in that the quantity is the same.
  According to this sanitary washing device, when the tip of the washing nozzle draws a curved path, the amount of change in the angle of the axis of the washing nozzle with respect to the horizontal plane is the same as the amount of change in the angle of the drive unit with respect to the horizontal plane. . Therefore, the relationship between the push-out amount of the drive unit and the advance amount of the cleaning nozzle can be kept linear. Thereby, a washing nozzle can be advanced stably.
According to a fifth aspect of the present invention, in the third or fourth aspect of the invention, the rotating shaft further guides and regulates the movement of the cleaning nozzle when the tip portion draws the curved path, the rotating shaft being The sanitary washing device is provided on the tip side of the washing nozzle in the housed state .
  According to this sanitary washing apparatus, the rotation shaft is provided on the tip side of the washing nozzle in the housed state. Therefore, when the cleaning nozzle transitions to a posture in which the angle of the axis of the cleaning nozzle with respect to the horizontal plane increases and changes from the housed state to the advanced state, the displacement amount of the front end of the cleaning nozzle is It is smaller than the displacement at the upper end. Therefore, the space in which the cleaning nozzle moves can be suppressed on the front side of the sanitary cleaning device. Thereby, the sanitary washing apparatus can be made compact.
In addition, a sixth invention is the invention according to any one of the first to fifth inventions, wherein the drive unit is disposed on a rear end side of the cleaning nozzle, and moves upward and downward in conjunction with the movement of the cleaning nozzle. This is a sanitary washing device characterized in that
  According to this sanitary washing device, the drive unit is disposed on the rear end side of the washing nozzle and is displaced upward and downward in conjunction with the movement of the washing nozzle. Therefore, even when a liquid such as water adheres to the cleaning nozzle, the liquid can be prevented from adhering to the driving unit. Thereby, it can suppress that a drive part fails with a liquid.
In addition, a seventh invention according to any one of the first to sixth inventions, further includes a base that slidably supports the cleaning nozzle and interlocks with the movement of the cleaning nozzle, and the drive unit includes The sanitary washing device is fixed to the base.
  According to this sanitary washing apparatus, the drive unit is fixed to the base that is interlocked with the movement of the washing nozzle. Therefore, the relative position of the drive unit and the base does not change depending on the movement of the cleaning nozzle. Therefore, the relationship between the push-out amount of the drive unit and the advance amount of the cleaning nozzle can be kept linear. Thereby, a washing nozzle can be advanced stably.
The eighth invention is the sanitary washing apparatus according to any one of the first to sixth inventions, wherein the washing nozzle is a multistage washing nozzle having a plurality of movable parts.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a schematic perspective view showing a toilet apparatus provided with a sanitary washing device according to an embodiment of the present invention.
  The toilet device shown in FIG. 1 includes a Western-style seat toilet (hereinafter simply referred to as “toilet” for convenience of explanation) 800 and a sanitary washing device 100 provided thereon. 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.
FIG. 3 is a graph showing the relationship between the push-out amount of the nozzle motor and the advance amount of the cleaning nozzle.
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. FIG. 3 shows the advancement amount of the cleaning nozzle 473 itself with reference to the initial position (position in the storage state) of the cleaning nozzle 473.
  As shown in FIG. 2, the nozzle unit 470 of the present embodiment includes a base 475, a cleaning nozzle 473 supported by the base 475, and a nozzle motor (drive unit) 476 that moves the cleaning nozzle 473. Have. 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 cleaning nozzle 473 has 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 making a transition to a posture in which the angle θ (see FIG. 5) of the shaft 473c of the cleaning nozzle 473 with respect to a horizontal surface 850 (see FIG. 5) such as the upper surface of the toilet 800 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. As will be described later with reference to FIG. 4, the distal end portion 473 a of the cleaning nozzle 473 advances while drawing a curved track 491, and then advances while drawing a straight track 493.
  Here, for example, when the nozzle motor 476 is fixed to the casing 400, the relative positions of the nozzle motor 476 and the base 475 change as the cleaning nozzle 473 advances. Then, when the tip portion 473a of the cleaning nozzle 473 advances while drawing the curved track 491, the driving force transmitted from the nozzle motor 476 to the nozzle head 471 may be absorbed and changed by the advancement of the cleaning nozzle 473. Therefore, there is a possibility that the relationship between the push-out amount of the nozzle motor 476 and the advance amount of the cleaning nozzle 473 is not linear as shown by a curve 503 shown in FIG. As a result, the cleaning nozzle 473 cannot be stably advanced, and even when the user adjusts the position of the cleaning nozzle 473, the cleaning nozzle 473 may not be accurately moved to a predetermined position. When the tip 473a of the cleaning nozzle 473 advances while drawing a straight track 493, the relationship between the amount of extrusion of the nozzle motor 476 and the amount of advance of the cleaning nozzle 473 is the relationship between the straight line 504 shown in FIG. Becomes linear.
  On the other hand, in this embodiment, the nozzle motor 476 is fixed to the base 475. In addition, since the cleaning nozzle 473 is slidably provided with respect to the base 475, the base 475 is advanced by the cleaning nozzle 473 as shown in FIGS. 2 (a) and 2 (b). Transition to a standing posture in conjunction with Therefore, the nozzle motor 476 is displaced in conjunction with the advance of the cleaning nozzle 473. The relative position between the base 475 and the nozzle motor 476 does not change depending on the advance of the cleaning nozzle 473.
  Thereby, the driving force transmitted from the nozzle motor 476 to the nozzle head 471 is kept substantially constant. That is, the driving force transmitted from the nozzle motor 476 to the nozzle head 471 does not cause a loss when the cleaning nozzle 473 moves forward while shifting to a posture in which the cleaning nozzle 473 stands up from the housed state. Or when the front-end | tip part 473a of the washing nozzle 473 advances while drawing the curved track 491 and the linear track 493, the relationship between the amount of extrusion of the nozzle motor 476 and the amount of advance of the cleaning nozzle 473 is shown in FIG. It becomes linear like a straight line 501. Here, “linear” means that the relationship between the push-out amount of the nozzle motor 476 and the advance amount of the cleaning nozzle 473 is expressed by a linear expression. Therefore, the cleaning nozzle 473 can advance with a substantially constant driving force transmitted from the nozzle motor 476. 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. In addition, the cleaning nozzle 473 can be accurately moved to a predetermined position, and it is possible to prevent the cleaning nozzle 473 from being pushed out more than necessary to advance.
Next, the advancing operation of the cleaning nozzle will be described in detail with reference to the drawings.
FIG. 4 is a schematic plan view illustrating the path of the cleaning nozzle of this embodiment.
5 and 6 are schematic plan views showing the nozzle unit of the present embodiment.
FIG. 7 is a schematic cross-sectional view showing the nozzle unit of this embodiment.
4 to 6 are schematic plan views of the nozzle unit 470 of the present embodiment as viewed from the right side. FIG. 7 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. Further, in the nozzle unit 470 shown in FIG. 6, the nozzle motor 476 is omitted for convenience of explanation.
  As shown in FIGS. 5 to 7, 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.
  As shown in FIG. 7, a cable rack (transmission unit) 478 is fixed to the nozzle head 471. 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 (transmission portions) 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. 4 to 6, 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. 4 and 6, 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, 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 regulating portion 453, the tip portion of the cleaning nozzle 473 (tip 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.
  Here, as described above with reference to FIGS. 2 and 3, the base 475 transitions to a posture of standing up in conjunction with the advancement of the cleaning nozzle 473. 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. Alternatively, the relationship between the push-out amount 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.
  The nozzle motor 476 is provided on the rear end side of the cleaning nozzle 473. Then, as shown in FIG. 4, the nozzle motor 476 is displaced upward and downward in conjunction with the advance / retreat of the cleaning nozzle 473. Therefore, even when a liquid such as water adheres to the cleaning nozzle, the liquid can be prevented from adhering to the nozzle motor 476. Thereby, it can suppress that the nozzle motor 476 fails with a liquid.
  Further, the rotation shaft 463 located at the rotation center of the cylinder 461 is provided on the distal end side of the cleaning nozzle 473 in the housed state. Therefore, when the fitting part 477b slides on the curve restriction part 453, the displacement amount of the tip part 473a of the cleaning nozzle 473 is such that the rear end part and the upper end part (upper end part of the slider 477) 477a of the cleaning nozzle 473 are changed. It is smaller than the displacement. For example, the length of the curved track 491 of the tip portion 473a of the cleaning nozzle 473 is shorter than the length of the track 495 of the upper end portion 477a of the slider 477. Therefore, the space in which the cleaning nozzle 473 moves on the front side of the sanitary cleaning device 100 can be suppressed. Thereby, the sanitary washing apparatus 100 can be made compact.
  Further, as exemplified in the present embodiment, when the cleaning nozzle 473 is a multistage cleaning nozzle, at least a part of the nozzle head 471 can be stored in the cylinder 472. Therefore, the length of the cleaning nozzle 473 in the accommodated state in the axis 473c direction can be further shortened. 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 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.
  Further, in 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, 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. 5 to 7) 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. 8 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. 9 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. 10 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. 4 to 7, 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. 8, 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.
On the other hand, as shown in FIG. 10, the cleaning nozzle 473 of this embodiment 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. Therefore, as shown in FIG. 9, 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. Further, as shown in FIGS. 9 and 10, the cleaning nozzle 473 in the advanced state and during the extended state does 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. As a result, 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 enough to cause the shaft 473c of the stored cleaning nozzle 473 to interfere 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.
Next, another embodiment of the present invention will be described.
FIG. 11 is a schematic plan view showing a nozzle unit according to another embodiment of the present invention.
In the nozzle unit shown in FIG. 11, 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. 11, the cleaning nozzle 473 advances while changing to a posture in which the angle θ (see FIG. 5) 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 restriction portion 453, the tip portion 473a of the cleaning nozzle 473 advances while drawing a curved track 491 (see FIG. 4).
  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 the present embodiment, even when the cleaning nozzle 473 is not a multi-stage type but a single-stage type, the nozzle motor 476 is displaced in conjunction with the advancement of the cleaning nozzle 473. The relative position between the base 475 and the nozzle motor 476 does not change depending on the advance of the cleaning nozzle 473.
  Thereby, the driving force transmitted from the nozzle motor 476 to the cleaning nozzle 473 is kept substantially constant. That is, the driving force transmitted from the nozzle motor 476 to the cleaning nozzle 473 does not cause a loss when the cleaning nozzle 473 advances while making a transition to a posture in which the cleaning nozzle 473 stands up from the housed state. Or when the front-end | tip part 473a of the washing nozzle 473 advances while drawing the curved track 491 and the linear track 493, the relationship between the amount of extrusion of the nozzle motor 476 and the amount of advance of the cleaning nozzle 473 is shown in FIG. Each of the lines 501 and 502 is linear. Therefore, the cleaning nozzle 473 can advance with a substantially constant driving force transmitted from the nozzle motor 476. 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.
  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. 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.
  The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention. For example, the shape, size, material, arrangement, etc. of each element included in the nozzle unit 470, the trajectory guide 450, and the like, and the installation form of the cleaning nozzle 473 and the nozzle motor 476 are not limited to those illustrated, but may be changed as appropriate. be able to. For example, the nozzle motor 476 may be installed separately for a motor that changes the angle of the cleaning nozzle 473 and a motor that advances the cleaning nozzle 473. Moreover, each element with which each embodiment mentioned above is provided can be combined as long as technically possible, and the combination of these is also included in the scope of the present invention as long as it includes the features of the present invention.
