Description

  Aspects of the invention generally relate to a sanitary washing apparatus.

  In order to be able to clean the upper surface portion of the toilet bowl on which the sanitary washing device is installed, a sanitary washing device is known in which a functional unit of the sanitary washing device can be raised and lowered with respect to the upper surface of the toilet bowl. For example, in the sanitary washing device described in Patent Document 1, the front side of the casing can be raised by manually operating the handle.

However, since the handle is provided on the side portion of the sanitary washing device, there is room for improvement in the design of the sanitary washing device.
In general, the gap between the side surface of the sanitary washing device and the wall surface of the toilet room is relatively narrow. Moreover, the installation position of the handle is relatively low. Therefore, there is room for improvement in the operability of the handle.

On the other hand, there is toilet equipment provided with a lifting device that lifts and lowers the toilet seat support member by electric operation instead of manual operation (Patent Document 2).
However, in the toilet equipment described in Patent Document 2, the rotational motion of the stepping motor is converted into linear motion by a rack and a pinion. Therefore, there exists a problem that a raising / lowering apparatus enlarges. As a result, there is a problem that the sanitary washing device becomes large and impairs the design of the sanitary washing device.

Inside the casing 200, a local cleaning function unit that realizes cleaning of a user who sits on the toilet seat 300, such as “wet”, is incorporated. A control unit 201 is provided inside the casing 200. The control unit 201 controls the operation of the local cleaning function unit and the operation of the elevating unit 500 described later (see FIGS. 3A and 3B).

  In addition, the inside of the casing 200, for example, sucks air in the bowl 810 of the toilet bowl 800 and reduces the odor component through a filter, a catalyst, or the like, or a “butt” of a user sitting on the toilet seat 300 For example, a warm air drying function unit that blows hot air toward the interior and the like, or an indoor heating function unit that blows warm air into the toilet room to heat the toilet room may be incorporated.

  A panel 830 is provided on the rear side of the toilet bowl 800. According to this, since the panel 830 can cover the side surface of the toilet bowl 800 or the appropriately provided pipes, the design can be ensured.

  For example, when the user performs a predetermined operation on the operation unit 860 (see FIG. 5) such as a remote controller, the front side of the casing 200 is electrically driven around the rear side of the casing 200 as indicated by an arrow A1 shown in FIG. , And can be lifted away from the upper surface 820 of the toilet bowl 800.

  Then, as illustrated in FIG. 2, a larger gap is formed between the casing 200 and the upper surface 820 of the toilet bowl 800 before a predetermined operation is performed in the operation unit 860, that is, before the front side of the casing 200 is raised. Occurs in The predetermined operation in the operation unit 860 will be described later.

  According to this, the user puts a cleaning tool, a hand, or the like through a gap between the casing 200 and the upper surface 820 of the toilet bowl 800, so that the gap portion or between the casing 200 and the toilet bowl 800 is inserted. It is possible to easily clean the sealing material 221 and the like that prevent the intrusion of dirty water. Further, since the front side of the casing 200 can be automatically raised and lowered by electric drive, it is not necessary to install a manual handle or the like. Therefore, it is possible to provide the sanitary washing device 100 in which the designability is not impaired and the cleaning property and the operability are improved. In addition, the sealing material 221 is provided between the lower surface of the casing 200 and the upper surface 820 of the toilet bowl 800 as will be described later.

  In addition, it is possible to prevent dirt and dust from accumulating in the gap between the casing 200 and the upper surface 820 of the toilet bowl 800, and the state where the dirt remains attached to the sealing material 221. Therefore, it is possible to suppress the generation of a strange odor from the gap between the upper surface 820 of the toilet bowl 800 and the sealing material 221. Furthermore, in the present embodiment, the entire casing 200 is not raised, but the front side of the casing 200 is rotated and raised, so that water is supplied to and supplied to various functional components built in the casing 200. The pipes and wiring used for them hardly expand or contract. Therefore, at the time of raising and lowering the front side of the casing 200, there is little possibility that these pipes and wirings are broken or damaged.

Next, the mechanism and operation for raising the front side of the casing 200 will be described in more detail with reference to the drawings.
FIG. 3 is a schematic perspective view of the casing according to the present embodiment as viewed from below.
FIG. 4 is a schematic cross-sectional view of a state in which the front side of the casing is raised from the side.
FIG. 5 is a schematic plan view illustrating an example of the operation unit of the present embodiment.
FIG. 3A is a schematic perspective view showing a state where the front side of the casing is lowered. FIG. 3B is a schematic perspective view showing a state where the front side of the casing is raised.

  As illustrated in FIGS. 3A and 3B, the casing 200 includes a case cover 210, a case plate 220, and an elevating part cover 230. Functional components such as a local cleaning function are appropriately placed on the case plate 220 and the upper part thereof is covered with a case cover 210. The elevating part cover 230 is provided on the lower surface of the case plate 220. As shown in FIG. 3A and FIG. 3B, a seal member 221 having a straight portion or a curved portion is attached to the lower surface of the case plate 220 so as to substantially follow the shape of the bowl 810 of the toilet bowl 800. Has been. That is, the sealing material 221 is attached to the front end portion on the bowl 810 side on the lower surface of the case plate 220.

  However, the installation position of the sealing material 221 is not limited to this, and may be attached to the upper surface 820 of the toilet bowl 800. Alternatively, the sealing material 221 may be attached to both the lower surface of the case plate 220 and the upper surface 820 of the toilet bowl 800. In the present embodiment, the case where the sealing material 221 is attached to the lower surface of the case plate 220 will be described as an example.

  The sealing material 221 is made of an elastic material such as rubber. Therefore, when the casing 200 is installed on the upper surface 820 of the toilet bowl 800, the sealing material 221 is compressed and deformed and comes into close contact with the upper surface 820 of the toilet bowl 800. Therefore, the sealing material 221 can prevent sewage from entering between the casing 200 and the toilet bowl 800.

  Between the case plate 220 and the lifting / lowering part cover 230, a lifting / lowering part 500 that lifts and separates the front side of the casing 200 from the upper surface 820 of the toilet bowl 800 is provided. As illustrated in FIG. 3A and FIG. 3B, the elevating unit 500 includes a support column (receiving unit) 550. The support column 550 can rotate in conjunction with the rotation of the rotation shaft 530 (see FIG. 6).

  The casing 200 is attached to the toilet bowl 800 by a fixture 240 on the rear side. The casing 200 can rotate with respect to the toilet bowl 800 around the portion attached by the fixture 240. Details of the fixture 240 will be described later.

  In a state where the front side of the casing 200 is lowered (see FIG. 3A), for example, when the user performs a predetermined operation on the operation unit 860, the support column 550 receives the rotational force transmitted via the rotation shaft 530. Receiving and rotating as shown in FIG. That is, the support column 550 is in an inverted state when viewed from the lower surface of the case plate 220.

  Examples of the predetermined operation on the operation unit 860 include an operation on a menu screen of the operation unit 860. Specifically, as illustrated in FIG. 5, the operation unit 860 of this embodiment includes an operation button 861 and a display unit 863. For example, the user causes the display unit 863 to display a menu screen by appropriately operating the operation buttons 861. Subsequently, for example, the user selects “1. Care” from the menu screen displayed on the display unit 863 by appropriately operating the operation buttons 861. Subsequently, for example, the user selects “up” or “down” from the “1. Maintenance” items by appropriately operating the operation buttons 861. For example, when the user selects “lift” from the “1. care” item, the column 550 is in an inverted state as viewed from the bottom surface of the case plate 220 from the state in which it is housed in the elevating unit cover 230. Become. On the other hand, for example, when the user selects “Descent” from the “1. Maintenance” item, the support column 550 is housed inside the elevating unit cover 230 from an inverted state when viewed from the lower surface of the case plate 220. It becomes a state.

As shown in FIG. 4, the support column 550 is supported by a guide plate (plate portion) 840 installed inside the toilet bowl 800 when viewed from the lower surface of the case plate 220. As a result, the support column 550 can lift and separate the front side of the casing 200 from the upper surface 820 of the toilet bowl 800. When the support column 550 rotates, one end portion 551 of the support column 550 slides on the surface of the guide plate 840 while abutting on the surface. At this time, the support column 550 and the guide plate 840 are made of a material having better sliding properties such as resin. Further, the one end portion 551 of the support column 550 has a substantially circular cross-sectional shape. Therefore, the support column 550 can smoothly slide on the surface of the guide plate 840.
The guide plate 840 may be attached to the case plate 220 instead of inside the toilet bowl 800.

  According to this, the user can raise and separate the front side of the casing 200 from the upper surface 820 of the toilet bowl 800 automatically and electrically. Thereby, the sealing material 221 attached to the lower surface of the case plate 220 can be separated from the upper surface 820 of the toilet bowl 800. Therefore, as described above with reference to FIG. 1 and FIG. 2, the user inserts a cleaning tool, a hand, or the like through a gap between the casing 200 and the upper surface 820 of the toilet bowl 800, so that the gap portion or the sealing material is inserted. 221 etc. can be easily cleaned. Further, since the front side of the casing 200 can be automatically raised and lowered by electric drive, it is not necessary to install a manual handle or the like. Therefore, it is possible to provide the sanitary washing device 100 in which the designability is not impaired and the cleaning property and the operability are improved.

  On the other hand, when the casing 200 is not raised or lowered, the front side and the rear side are respectively fixed to the toilet bowl 800 by the elevating part 500 and the fixture 240, so that when the user sits on the toilet seat 300, A sense of stability can be secured. Moreover, the raising / lowering part 500 and the guide plate 840 can be made into a simple structure, and an raising / lowering function can be added to a toilet apparatus, without requiring a significant cost increase.

Next, the raising / lowering part 500 of this embodiment is demonstrated, referring drawings.
FIG. 6 is a schematic perspective view showing the elevating unit of the present embodiment.

  The elevating unit 500 of this embodiment includes a motor 501, a reduction gear 510, a rotation shaft 530, a first spring 503, a support column 550, a stopper unit 570, and a guide plate 840. The motor 501, the reduction gear 510, the rotation shaft 530, and the first spring 503 are provided inside the elevating unit cover 230. As described above with reference to FIGS. 3A and 3B, the lift cover 230 is provided on the lower surface of the case plate 220. Therefore, the motor 501, the reduction gear 510, the rotation shaft 530, and the first spring 503 are provided between the elevating part cover 230 and the lower surface of the case plate 220.

The motor 501 performs a rotational motion based on a signal transmitted from the control unit 201, and generates a rotational force (torque). The motor 501 of this embodiment is a stepping motor. However, the motor 501 is not limited to a stepping motor, and may be a DC motor, for example. Hereinafter, a case where the motor 501 is a stepping motor will be described as an example.
In the elevating part 500 shown in FIG. 6, the reduction gear 510 has a first gear part 511, a second gear part 512, and an output gear part 540. However, the number of gear portions included in the reduction gear 510 is not limited to this. For example, the reduction gear 510 may have only the output gear portion 540. About the number of gear parts, it can change suitably according to the reduction ratio of the reduction gear 510. FIG. In addition, the reduction ratio of the reduction gear 510 of this embodiment is about 1/300 or more and 1/290 or less, for example.

The rotation shaft 530 is connected to the output gear portion 540 and rotates in conjunction with the output gear portion 540. The rotation shaft 530 is rotated by the rotational force transmitted from the motor 501 via the reduction gear 510.
The column 550 is connected to the rotation shaft 530 and rotates in conjunction with the rotation shaft 530.

  The first spring 503 assists the rotation of the rotation shaft 530. Specifically, the first spring 503 biases the rotation shaft 530 in a direction in which the support column 550 is inverted when viewed from the lower surface of the case plate 220. Thereby, the load torque of the motor 501 can be suppressed.

The detent torque of the motor 501 transmitted to the rotation shaft 530 via the reduction gear 510 is larger than the torque generated on the rotation shaft 530 based on the force of the first spring 503 (see FIG. 14).
In the present specification, “detent torque” refers to torque generated in the motor 501 in a state where the motor 501 is not energized.

  Thereby, when the sanitary washing device 100 exists alone, the support column 550 can maintain a substantially horizontal state. In other words, when the sanitary washing device 100 is present alone, it is possible to prevent the support column 550 from being inverted when viewed from the lower surface of the case plate 220. Therefore, it can suppress that the support | pillar 550 protrudes from the casing 200 in the case of an assembly, packing, and conveyance. Therefore, assembling property, packing property and transportability can be ensured.

  The stopper part 570 has a claw part 573. The claw portion 573 is provided at the distal end portion of the stopper portion 570. As shown in FIG. 6, a second spring 575 is provided inside the elevating unit cover 230. The second spring 575 biases the stopper portion 570 backward. Accordingly, as shown in FIG. 6, when the stopper portion 570 is not receiving a force other than the urging force of the second spring 575, the claw portion 573 of the stopper portion 570 is moved to the rear of the elevating portion cover 230. It protrudes. On the other hand, when the stopper portion 570 receives a force greater than a predetermined value in a direction opposite to the biasing force of the second spring 575, the claw portion 573 of the stopper portion 570 is pushed into the elevating portion cover 230. .

  The guide plate 840 has a wall portion 843. A stopper fitting portion 847 is provided on the wall portion 843. In the guide plate 840 shown in FIG. 6, the stopper fitting portion 847 has a first fitting hole 847a, a second fitting hole 847b, and a third fitting hole 847c. However, the number of fitting holes provided in the stopper fitting portion 847 is not limited to this, and may be one, two, or four or more. Moreover, the stopper fitting part 847 is not limited to having a hole, and may have a groove.

  When the casing 200 is lowered, the claw portion 573 of the stopper portion 570 is fitted with the stopper fitting portion 847. For example, when the casing 200 is lowered, the claw portion 573 of the stopper portion 570 is engaged with one of the first fitting hole 847a, the second fitting hole 847b, and the third fitting hole 847c. . Thereby, when the casing 200 is lowered, the front side of the casing 200 is fixed to the guide plate 840 installed in the toilet bowl 800. Therefore, the stopper portion 570 can prevent the casing 200 from rising from the upper surface 820 of the toilet bowl 800, and can ensure a sense of stability when the user sits on the toilet seat 300.

According to the lifting / lowering unit 500 of the present embodiment, the front side of the casing 200 can be lifted / lowered automatically by electric power, so that it is not necessary to install a manual handle or the like. Therefore, it is possible to provide the sanitary washing device 100 in which the designability is not impaired and the cleaning property and the operability are improved.
The elevating unit 500 has a structure for transmitting the rotational movement of the motor 501 to the rotation shaft 530 and rotating the rotation shaft 530. Thereby, the raising / lowering part 500 can be automated with a simple structure, and it can suppress that the raising / lowering part 500 enlarges. As a result, the design of the sanitary washing device 100 can be improved.

FIG. 7 is a schematic diagram for explaining the relationship among the output gear portion, the stopper release portion, and the rotation shaft.
FIG. 8 is a schematic diagram showing the output gear portion of the present embodiment.

Fig.7 (a) is a typical perspective view showing the inside of the raising / lowering part 500 of this embodiment. FIG. 7B is a schematic plan view when the output gear portion 540 is viewed in the direction of the arrow A11 illustrated in FIG. In FIG. 7A, for convenience of explanation, the guide plate 840, the elevating part cover 230, the support column 550, and the second spring 575 are omitted.
FIG. 8A and FIG. 8B are schematic perspective views showing the output gear portion of the present embodiment. FIG. 8C is a schematic plan view showing the output gear portion of the present embodiment.

  As shown in FIGS. 8A to 8C, the output gear portion 540 has a through hole 541 in a substantially central portion. As shown in FIGS. 7A and 7B, the rotation shaft 530 and the stopper release portion 580 pass through the through hole 541 of the output gear portion 540.

The stopper release portion 580 has a first outer surface 581 and a second outer surface 582.
The output gear portion 540 has a first inner surface 542a and a second inner surface 542b inside the through hole 541. The first outer surface 581 of the stopper release portion 580 is in contact with the first inner surface 542a of the output gear portion 540. The second outer surface 582 of the stopper release portion 580 is in contact with the second inner surface 542b of the output gear portion 540. Thereby, the stopper release part 580 rotates with the rotational movement of the output gear part 540.
The rotation shaft 530 has a first outer surface 531 and a second outer surface 532.
The output gear portion 540 has a third inner surface 543a, a fourth inner surface 543b, a fifth inner surface 544a, and a sixth inner surface 544b inside the through hole 541. In a state where the casing 200 is lowered (a state where the claw portion 573 of the stopper portion 570 is fitted with the stopper fitting portion 847), the first outer surface 531 of the rotating shaft 530 is the third inner surface 543a of the output gear portion 540. In contact with. In a state where the casing 200 is lowered (a state where the claw portion 573 of the stopper portion 570 is engaged with the stopper fitting portion 847), the second outer surface 532 of the rotating shaft 530 is the fourth inner surface 543b of the output gear portion 540. In contact with.

  When the rotational force of the motor 501 is transmitted to the output gear portion 540, the output gear portion 540 rotates in the direction of the arrow A12 shown in FIG. Then, the stopper release part 580 rotates together with the output gear part 540. That is, there is almost no play between the output gear portion 540 and the stopper release portion 580.

On the other hand, even if the output gear portion 540 rotates in the direction of the arrow A12 shown in FIG. 7B, the rotation shaft 530 does not rotate immediately. That is, when the output gear portion 540 rotates in the direction of the arrow A12 shown in FIG. 7B, the third inner surface 543a of the output gear portion 540 moves away from the first outer surface 531 of the rotation shaft 530. Similarly, the fourth inner surface 543 b of the output gear portion 540 is separated from the second outer surface 532 of the rotation shaft 530. For this reason, a gap is generated between the output gear portion 540 and the rotation shaft 530.
When the output gear portion 540 further rotates in the direction of the arrow A <b> 12 shown in FIG. 7B, the fifth inner surface 544 a of the output gear portion 540 comes into contact with the first outer surface 531 of the rotation shaft 530. Similarly, the sixth inner surface 544 b of the output gear portion 540 comes into contact with the second outer surface 532 of the rotation shaft 530. Thereby, the rotation shaft 530 rotates together with the output gear portion 540. That is, there is play between the output gear portion 540 and the rotation shaft 530.

  As illustrated in FIG. 10C, the support column 550 includes a first through hole 552 and a second through hole 553 at the end opposite to the one end 551. As shown in FIGS. 9A and 9B, the rotation shaft 530 passes through the first through hole 552 of the support column 550. The stopper release portion 580 passes through the second through hole 553 of the support column 550. In the support column 550 illustrated in FIG. 10, the first through hole 552 is connected to the second through hole 553. However, the first through hole 552 may be provided separately from the second through hole 553.

  The support column 550 has a first inner surface 552a and a second inner surface 552b inside the through hole 552. As shown in FIG. 9B, the first outer surface 531 of the rotation shaft 530 is in contact with the first inner surface 552 a of the support column 550. The second outer surface 532 of the rotation shaft 530 is in contact with the second inner surface 552b of the support column 550. As a result, the support column 550 rotates with the rotation of the rotation shaft 530.

  When the rotational force of the motor 501 is transmitted to the rotation shaft 530 via the output gear portion 540, the rotation shaft 530 rotates in the direction of the arrow A14 shown in FIG. 9B. Then, the support column 550 rotates together with the rotation shaft 530. That is, there is almost no play between the rotating shaft 530 and the support column 550.

  As described above, the stopper release portion 580 passes through the second through hole 553 of the support column 550. As shown in FIG. 10A to FIG. 10C, the second through hole 533 has a shape that penetrates the support column 550 in a substantially semicircular shape when viewed in the direction shown in FIG. 9A. Have. Thereby, the stopper release part 580 can move (turn) inside the second through hole 533. In other words, depending on the position inside the second through-hole 533, the stopper release portion 580 can maintain a stationary state even if the column 550 is rotated. That is, there is play between the column 550 and the stopper release portion 580.

Next, the ascending operation of the elevating unit 500 of this embodiment will be described with reference to the drawings.
FIG. 11 is a schematic cross-sectional view illustrating the ascending operation of the elevating unit according to the present embodiment.
FIG. 11A to FIG. 11F are schematic cross-sectional views taken along the cutting plane AA shown in FIG.
Fig.11 (a) and FIG.11 (b) are typical sectional drawings showing the state (state where the front side of the casing fell) before the front side of a casing raises. FIG.11 (c) and FIG.11 (d) are typical sectional drawings showing the state immediately after the front side of a casing started a raise. FIG.11 (e) and FIG.11 (f) are typical sectional drawings showing the state in which the front side of a casing is raising.

  As shown in FIG. 11A and FIG. 11B, in the state before the front side of the casing 200 rises, a part of the second outer surface 582 of the stopper release portion 580 is formed on the stopper portion 570. The protrusion 577 is in contact. The protrusion 577 is provided at the end of the stopper 570 opposite to the claw 573. For example, when the user inputs an operation to raise the casing 200 through the operation unit 860, the control unit 201 performs control for energizing the motor 501 and starting the rotational movement of the motor 501.

  When the rotational force of the motor 501 is transmitted to the output gear portion 540, the stopper release portion 580 causes the output gear portion 540 to move in the direction of the arrow A21 shown in FIG. 11A and the arrow A22 shown in FIG. It rotates with. On the other hand, since there is play between the output gear portion 540 and the rotation shaft 530, the support column 550 has not yet started to rotate. These are as described above with reference to FIGS. 7A to 8C.

  Subsequently, when the stopper release portion 580 further rotates in the direction of the arrow A23 shown in FIG. 11 (c) and the arrow A24 shown in FIG. 11 (d), of the second outer surface 582 of the stopper release portion 580 A part pushes the projection 577 of the stopper 570 forward while resisting the biasing force of the second spring 575 (see FIG. 6). As a result, the stopper portion 570 moves in the directions of the arrow A25 shown in FIG. 11C and the arrow A26 shown in FIG.

  Subsequently, when the stopper releasing portion 580 is further rotated in the direction of the arrow A27 shown in FIG. 11E and the arrow A28 shown in FIG. 11F, the stopper portion 570 is shown in FIG. It further moves in the direction of arrow A29 and arrow A31 shown in FIG. That is, the stopper portion 570 is retracted from the stopper fitting portion 847. Thereby, the fitting state of the claw part 573 of the stopper part 570 and the stopper fitting part 847 is released. Therefore, the casing 200 can be raised from the upper surface 820 of the toilet bowl 800.

  Subsequently, when the output gear portion 540 further rotates, the fifth inner surface 544 a of the output gear portion 540 comes into contact with the first outer surface 531 of the rotation shaft 530. Further, the sixth inner surface 544 b of the output gear portion 540 is in contact with the second outer surface 532 of the rotation shaft 530. Then, the rotation shaft 530 rotates together with the output gear portion 540. This is as described above with reference to FIGS. 7A to 8C. Then, the support | pillar 550 rotates in the direction of arrow A32 represented to FIG.11 (f) with the rotational motion of the rotating shaft 530. FIG. This is as described above with reference to FIGS. 9A to 10C.

  Here, as illustrated in FIG. 11F, the stopper release portion 580 has an outer peripheral surface 583 connected to the first outer surface 581 and the second outer surface 582. When the stopper release portion 580 further rotates from the state shown in FIG. 11E and FIG. 11F, the outer peripheral surface 583 of the stopper release portion 580 slides on the tip portion 577a of the projection portion 577 of the stopper portion 570. To do. Accordingly, the protrusion 577 of the stopper 570 is not pushed further forward from the state shown in FIGS. 11E and 11F. That is, the stopper portion 570 is held in a state where the fitting state with the stopper fitting portion 847 is released.

  Subsequently, when the column 550 is further rotated, the column 550 is inverted as viewed from the lower surface of the case plate 220 and is supported by the guide plate 840. Thereby, the front side of the casing 200 rises from the upper surface 820 of the toilet bowl 800. When the front side of the casing 200 is raised from the upper surface 820 of the toilet bowl 800, detent torque is generated in the motor 501. The sum of the detent torque of the motor 501 transmitted to the rotating shaft 530 via the reduction gear 510 and the torque generated in the rotating shaft 530 based on the force of the first spring 503 is the weight of the sanitary washing device 100. Therefore, the torque applied to the rotation shaft 530 via the support column 550 is larger. Thereby, the state where the front side of casing 200 rose from upper surface 820 of toilet bowl 800 is maintained.

Thus, in the elevating part 500 of this embodiment, the fitting state between the claw part 573 of the stopper part 570 and the stopper fitting part 847 is released before the column 550 starts to rotate.
According to this, the stopper portion 570 and the support column 550 can be driven by one motor 501 and one rotation shaft 530. Therefore, the elevating part 500 can be made compact. Moreover, before the support | pillar 550 starts rotation, the fitting state of the nail | claw part 573 of the stopper part 570 and the stopper fitting part 847 is cancelled | released. For this reason, it is possible to prevent the lifting unit 500 from forcibly driving and damaging at least one of the guide plate 840 and the lifting unit cover 230.

The stopper release unit 580 starts to rotate when the output gear unit 540 starts to rotate, and releases the fitting state between the claw portion 573 of the stopper unit 570 and the stopper fitting unit 847. On the other hand, the support column 550 does not start rotating immediately after the output gear unit 540 starts rotating, and the fitting state between the claw portion 573 of the stopper unit 570 and the stopper fitting unit 847 is not changed. The rotation starts after being released.
According to this, the fitting state of the claw part 573 of the stopper part 570 and the stopper fitting part 847 can be more reliably released.

  On the other hand, when the rotational force in the direction opposite to the rotational force of the motor 501 described above with reference to FIGS. 11A to 11F is transmitted to the rotating shaft 530 via the output gear portion 540, The front side descends to the upper surface 820 of the toilet bowl 800. Then, the stopper portion 570 is moved by receiving the urging force of the second spring 575, and the claw portion 573 of the stopper portion 570 and the stopper fitting portion 847 are in a fitted state. That is, the control unit 201 drives the motor 501 to lower the front side of the casing 200 to the upper surface 820 of the toilet bowl 800, and then engages the claw portion 573 of the stopper portion 570 with the stopper fitting portion 847. And Thereby, after the front side of casing 200 falls to upper surface 200 of toilet bowl 800, it can control that a user lifts or moves casing 200.

The control unit 201 according to the present embodiment drives the motor 501 to fit the claw portion 573 of the stopper portion 570 and the stopper fitting portion 847 after a predetermined time has elapsed from the state where the front side of the casing 200 is raised. Execute control.
According to this, even when the user lowers the casing 200, the claw portion 573 of the stopper portion 570 and the stopper fitting portion 847 can be more reliably fitted. Therefore, it is possible to suppress the user from forcibly lifting or forcibly moving the casing 200.

  In addition, the control unit 201 of the present embodiment controls, for example, the pulse rate of the motor 501 and rotates the rotation shaft 530 when releasing the fitting state between the claw portion 573 of the stopper portion 570 and the stopper fitting portion 847. The control is executed to make the rotation speed of the rotation axis higher than the rotation speed of the rotation shaft 530 when the support column 550 rotates.

  According to this, the time until the casing 200 rises can be shortened. Therefore, it is possible to provide the sanitary washing device 100 that is easy to use for the user. Further, since the rotation speed of the rotation shaft 530 when the support column 550 rotates is slower than when the fitting state is released, the casing 200 can be reliably and safely raised.

  As described above, in the state before the front side of the casing 200 is raised, a part of the second outer surface 582 of the stopper release portion 580 is in contact with the protruding portion 577 of the stopper portion 570. In this state, when the claw portion 573 of the stopper portion 570 is pushed against the urging force of the second spring 575, the protruding portion 577 of the stopper portion 570 is separated from the stopper releasing portion 580. Therefore, even if the claw portion 573 of the stopper portion 570 is pressed against the urging force of the second spring 575, the rotation shaft 530 does not rotate via the stopper release portion 580.

  According to this, the sanitary washing apparatus 100 can be more reliably installed. That is, when the sanitary washing device 100 is installed in the toilet bowl 800, the stopper portion 570 contacts and moves with the stopper fitting portion 847 of the guide plate 840. At this time, the stopper portion 570 can be moved only by its own weight of the sanitary washing device 100. On the other hand, when removing the sanitary washing device 100, it is necessary to move the stopper portion 570 to release the restriction in the vertical direction. On the other hand, according to the present embodiment, by providing the manual approach means to the stopper portion 570, the stopper portion 570 can be released with a light force.

  The control unit 201 may be capable of executing an operation mode in which only the stopper unit 570 can be moved. In this case, the sanitary washing device 100 can be easily detached from the toilet bowl 800. As a result, operations such as maintenance are simplified and the user-friendly sanitary washing device 100 can be provided.

Next, operation | movement of the support | pillar 550 of this embodiment is demonstrated, referring drawings.
FIG. 12 is a schematic plan view for explaining the operation of the column according to this embodiment.
FIG. 13 is a schematic plan view for explaining another operation of the column according to the present embodiment.
FIG. 14 is a graph illustrating an example of the characteristics of the motor of this embodiment.

  As described above with reference to FIGS. 9A to 10C, when the turning force of the motor 501 is transmitted to the rotating shaft 530 via the output gear portion 540, the support column 550 is moved to the state shown in FIG. It rotates in the direction of the indicated arrow A41. As shown in FIGS. 12B and 14, a relatively large load torque is generated immediately after the support column 550 comes into contact with the bottom 841 (see FIG. 6) of the guide plate 840. Further, the torque (spring assist torque) generated in the rotation shaft 530 based on the force of the first spring 503 is relatively large.

  Subsequently, when the support column 550 further rotates in the direction of the arrow A42 shown in FIG. 12B, the amount of the front side of the casing 200 rising from the upper surface 820 of the toilet bowl 800 (the amount of increase) increases. Then, as shown in FIG. 14, the load torque and the spring assist torque decrease as the amount of increase increases.

  Therefore, the control unit 201 of the present embodiment executes control to reduce the current supplied to the motor 501 as the casing 200 increases, and to reduce the step-out torque of the motor 501.

According to this, it is possible to suppress an unnecessary load from being applied to the reduction gear 510 and to prevent the reduction gear 510 from being damaged.
That is, when the user applies a force in a downward direction to the sanitary washing device 100 in order to stop the sanitary washing device 100 from rising, the sanitary washing device 100 is not immediately after the sanitary washing device 100 starts to rise. It is often the stage where the user has noticed that the price is rising. Therefore, according to this embodiment, when the sanitary washing device 100 rises without the user's intention, the user tries to stop the rise of the sanitary washing device 100 in the descending direction with respect to the sanitary washing device 100. Even if a force is applied to, it is possible to suppress an unnecessary load from being applied to the reduction gear 510. Therefore, damage to the reduction gear 510 can be suppressed.

  Further, the reduction gear 510 can be prevented from being damaged by the control executed by the control unit 201. Therefore, the raising / lowering part 500 can be suppressed from increasing in size, and the raising / lowering part 500 having higher durability can be provided.

  As shown in FIG. 12A to FIG. 12C, the elevating part cover 230 of this embodiment has a contact part 231. As shown in FIG. 12C, when the support column 550 further rotates in the direction of the arrow A42 shown in FIG. 12B, the support column 550 comes into contact with the contact portion 231 of the elevating unit cover 230 and stops. Therefore, the amount of rise on the front side of the casing 200 is regulated to be constant.

  Alternatively, as illustrated in FIGS. 13A to 13C, the guide plate 840 has a contact portion 849. As shown in FIG. 13C, when the support column 550 further rotates in the direction of the arrow A42 shown in FIG. 13B, the support column 550 comes into contact with the contact portion 849 of the guide plate 840 and stops. Thereby, the amount of ascent on the front side of the casing 200 is regulated to be constant.

According to this, since the amount of ascent on the front side of the casing 200 is constant, the load on the motor 501, the rotation shaft 530, and the first spring 503 can be reduced. Therefore, durability of the raising / lowering part 500 can be improved. Moreover, since the rising amount of the front side of the casing 200 is constant, more reliable cleaning properties can be ensured.
Further, when the support column 550 comes into contact with the contact portion 849 of the guide plate 840 and stops, the guide plate 840 can be changed to cope with various models in which the rising amount of the casing 200 is different.

  As described above, the control unit 201 performs control to reduce the step-out torque of the motor 501 as the amount of increase in the casing 200 increases. Thereby, the impact when the support | pillar 550 contact | abuts to the contact parts 231 and 849 can be relieved. Therefore, it is possible to prevent a relatively large load from being applied to the reduction gear 510 and to ensure the durability of the reduction gear 510. Therefore, high reliability of the elevating unit 500 can be realized, and the life of the elevating unit 500 can be extended.

  As shown in FIGS. 12C and 13C, in the state in which the casing 200 is raised most, the shaft 530c of the rotating shaft 530 and the support column 550 are in a horizontal plane 880 (for example, the bottom 841 of the guide plate 840 or the toilet bowl). The angle θ formed between the straight line L1 connecting the point 550a in contact with the upper surface 820 of the 800 and the like and the horizontal plane 880 in the rotation direction of the column 550 when viewed from the column 550 is smaller than 90 degrees.

According to this, even if the motor 501 breaks down and the power is not supplied due to a power failure when the casing 200 is at its highest position, the casing 200 is manually pushed down to lower the front side of the sanitary washing device 100. Can be made. Therefore, the sanitary washing device 100 can be used even during a power failure.
Further, since the elevating unit 500 is provided in the casing 200, the inclination direction of the support column 550 is the same as the inclination direction of the casing 200. Therefore, it can suppress that the support | pillar 550 obstructs the cleaning of the upper surface 820 of the toilet bowl 800, or the lower surface of the casing 200. Therefore, it is possible for the user to provide the sanitary washing device 100 that is easy to use.

The angle θ of the support column 550 with respect to the horizontal plane 880 in the state where the casing 200 is most raised is held by the detent torque of the motor 501 transmitted to the rotating shaft 530 through the reduction gear 510.
According to this, the state in which the sanitary washing device 100 is most elevated can be maintained. Therefore, the load applied to the motor 501 can be reduced, and the heat generated when the ascent of the casing 200 is maintained for a long time can be suppressed. As a result, the life of the motor 501 and the life of the elevating unit 500 can be increased.
Alternatively, the angle θ of the support column 550 with respect to the horizontal plane 880 in the state where the casing 200 is most raised is based on the detent torque of the motor 501 transmitted to the rotating shaft 530 via the reduction gear 510 and the force of the first spring 503. Thus, the torque is held by the sum of the torque generated on the rotating shaft 530.
According to this, the state in which the sanitary washing device 100 is most elevated can be maintained. Further, the detent torque of the motor 501 can be reduced as compared with the case where the torque generated in the rotating shaft 530 based on the force of the first spring 503 is not used. Therefore, the motor 501 can be downsized. As a result, the elevating unit 500 can be downsized and the sanitary washing device 100 can be downsized.

Alternatively, the angle θ of the support column 550 with respect to the horizontal plane 880 in the state where the casing 200 is raised most is held by the holding torque of the motor 501.
In the present specification, “holding torque” refers to the maximum torque that can be generated while the motor 501 is stationary.

  According to this, the state in which the sanitary washing device 100 is most elevated can be maintained.

When the holding torque is generated in the motor 501 for a certain period of time, the heat generated in the motor 501 may affect the motor 501 itself.
On the other hand, the control unit 201 according to the present embodiment executes control for releasing the holding torque and lowering the casing 200 when a predetermined time has elapsed after the motor 501 generates the holding torque.
According to this, the influence of heat generated in the motor 501 can be suppressed. As a result, the life of the motor 501 can be extended.

The control unit 201 of the present embodiment notifies the user that the holding torque is released and the casing 200 is lowered using, for example, sound or light.
According to this, while the user is cleaning the upper surface 820 of the toilet bowl 800 and the back surface of the casing 200, the casing 200 is lowered and the user's hand is sandwiched between the casing 200 and the upper face 820 of the toilet bowl 800. Can be suppressed. Therefore, it is possible for the user to provide the sanitary washing device 100 that is easy to use.

Next, the fixture 240 of this embodiment will be described with reference to the drawings.
FIG. 15 is a schematic perspective view illustrating the fixture of the present embodiment.
FIG. 16 is a schematic cross-sectional view illustrating the fixture of the present embodiment.
FIG. 15A is a schematic perspective view showing the rear side of the toilet 800 of the present embodiment, and FIG. 15B is a schematic enlarged view of the vicinity of the fixture 240 of the present embodiment, that is, It is an expansion schematic diagram in area | region A3 represented to Fig.15 (a).
Moreover, Fig.16 (a) is typical sectional drawing in cut surface BB represented to FIG.15 (b). FIG. 16B is a schematic cross-sectional view taken along the cutting plane CC shown in FIG. FIG. 16C is a schematic cross-sectional view taken along the cutting plane DD shown in FIG.

  First, as shown in FIG. 15A, a toilet plate 850 is fixed to the upper rear portion of the toilet 800. The toilet plate 850 is made of, for example, resin. Further, as shown in FIG. 15B, the fixture 240 of the present embodiment includes a nut fixing member (fixing portion) 241, a nut 242 placed on the nut fixing member 241, and a nut 242. It has the fixture 245 which attaches the nut fixing member 241 to the toilet bowl plate 850 by being fastened, and the rotating shaft member 243 attached to the case plate 220 by the fixture 246.

  In addition, the structure of the vicinity of the fixture 240 of this embodiment is an example, and is not limited to this. For example, the nut fixing member 241 may be directly attached to the toilet bowl 800 by the fixture 245 without providing the toilet bowl plate 850. Further, the fixture 245 may be directly fastened to the nut fixing member 241 without the nut 242 being placed on the nut fixing member 241.

  As shown in FIG. 15B, the rotation shaft member 243 has a shaft portion 243a protruding from the surface. On the other hand, the nut fixing member 241 has a shaft insertion portion 241a into which the shaft portion 243a of the rotating shaft member 243 can be inserted, as shown in FIG. Then, as shown in FIG. 16C, the shaft portion 243 a of the rotating shaft member 243 attached to the case plate 220 by the fixture 246 is inserted into the shaft insertion portion 241 a of the nut fixing member 241. Note that the attachment method is not limited to this, and for example, the rotating shaft connected to the nut fixing member 241 after the shaft portion 243a of the rotating shaft member 243 is inserted into the shaft inserting portion 241a of the nut fixing member 241. The member 243 may be attached to the case plate 220 by the fixture 246.

  Subsequently, as shown in FIG. 16A and FIG. 16B, the nut fixing member 241 is fixed to the toilet plate 850 or the toilet 800 by fastening the fixture 245 to the nut 242. At this time, the nut fixing member 241 is housed in the recess 223 provided in the case plate 220 as shown in FIG. Therefore, the nut fixing member 241 does not interfere with the bottom surface of the case plate 220, and the case plate 220 does not lift from the upper surface 820 of the toilet bowl 800 due to the interference with the nut fixing member 241. Moreover, since the nut fixing member 241 is housed in the recess 223 and is not seen from the outside of the toilet device, the design of the toilet device is not impaired.

  The shaft portion 243a of the rotation shaft member 243 can rotate inside the shaft insertion portion 241a of the nut fixing member 241 as indicated by an arrow A4 shown in FIG. That is, the rotation shaft member 243 can rotate with respect to the nut fixing member 241 about the shaft portion 243a. As a result, the case plate 220 fixed to the rotating shaft member 243 can rotate around the shaft portion 243a with respect to the toilet plate 850 and the toilet 800 fixed to the nut fixing member 241. Thereby, the casing 200 can be rotated with respect to the toilet bowl 800 around the shaft portion 243a of the rotation shaft member 243 as indicated by an arrow A5 illustrated in FIG.
