For this reason, the main body 200 stops once before reaching the stationary position. Thereby, when moving a main-body part to a stationary position, the danger of pinching a finger | toe under the main-body part 200 can be avoided, and the safety at the time of moving a main body to the back accidentally during cleaning can be ensured.

  After the stop, the main body 200 is pushed backward while pushing the operating rod 808 in the direction of arrow A, the main body 200 is moved to the stationary position, and the connection pin 807 is connected to the through-hole 806 of the connection piece 805 and the connection receptacle. The main body 200 is fixed at a fixed position by being inserted into the through hole 835 of 834. In this operation, since it is essential to use both hands for the movement of the main body 200 and the operation rod 808, it is possible to prevent the risk of accidentally pinching a finger between the lower part of the main body 200.

  When the toilet seat lift up switch 334 is operated again in this state, both the toilet seat 400 and the lid 500 are closed, and the sanitary washing device can be operated.

  As described above, in the present embodiment, the movement of the main body is simply an operation of opening the movement restricting means and moving the main body forward, and the front of the main body is automatically lifted to form a gap. Therefore, the user can easily clean the concealing part of the toilet seat device with a simple operation, and the toilet device can always be used comfortably.

In addition, since the main body is lifted in a state where the main body has moved a predetermined distance forward, interference between the lid and the low tank can be prevented, so that the lid and the low tank are not damaged.
In this embodiment, the toilet seat lift-up switch 334 is operated so that both the toilet seat 400 and the lid 500 are opened, and other operations cannot be performed. Instead, the toilet seat 400 and the lid 500 may be opened manually, and the range of functions that cannot be operated may be limited.

In the present embodiment, the sliding guide 801 has a groove shape, and the engagement pieces 831 and 832 have a substantially cylindrical shape and a substantially semi-cylindrical shape. However, the present invention is not limited to these shapes. Is a plate-like shape, and the engagement piece is substantially U-shaped and holds the sliding guide.

  In this embodiment, the flat portion 802 of the sliding guide is substantially horizontal, but the present invention is not limited to this, and the flat portion may have a gentler inclination than the inclined portion. By providing a gentle slope in the flat part, the rear part of the main body part slightly rises in the raised position, and a gap is formed between the rear part of the main body part 200 and the toilet upper surface, so that the rear part can be cleaned. Play.

<2-1> Configuration of Sliding Coupling Unit and Driving Unit FIG. 9 is an exploded perspective view of the sliding coupling unit integrally provided with the driving unit in the second embodiment, and FIG. FIG. 11 is a perspective view showing the lower surface of the bottom plate 210 of the main body 200. FIG.

  The main difference between the present embodiment and the first embodiment is that in the first embodiment, the main body 200 is moved in the front-rear direction by human power, but in the present embodiment, a drive unit 860 is provided. The user can automatically move the main body 200 by operating the toilet seat lift-up switch 334. The toilet device 1000, the sanitary washing device 100, the toilet seat device 110, the main body 200, shown in FIG. The external appearances of the remote control device 300, the toilet seat 400, the lid 500, the entrance detection sensor 600 and the like are the same as those in the first embodiment.

  As shown in FIGS. 9 and 10, the bottom plate 210 having the elements of the sliding coupling portion 840 is provided with a drive portion 860 on the upper surface of the recessed portion 850. The drive unit includes an electric motor that is a drive source and a drive transmission mechanism that transmits a drive force to the main body unit 200.

  A DC motor 861 is installed as an electric motor of the drive unit, and the rotation of the DC motor 861 is transmitted to the drive transmission mechanism. The structure of the drive transmission mechanism is such that the rotation of the DC motor is deflected and decelerated substantially at right angles by a worm 862 that is directly connected to the rotating shaft of the DC motor 861 and a worm gear 863 that meshes with the worm 862. The rotation of the worm gear 863 is finally transmitted to a male screw-shaped screw shaft 865 via a plurality of reduction gears 864.

  The axial direction of the screw shaft 865 is arranged in the front-rear direction so as to be parallel to the sliding guide 801. Each element of the drive unit 860 is supported by a drive support unit 866.

  The screw shaft 865 is fitted with a female screw-shaped screw receiver 867, and the screw receiver 867 is movable in the front-rear direction when the screw shaft 865 rotates. A coupling receiver 868 is coupled to the screw receiver 867 and moves back and forth in conjunction with the screw receiver 867. The connection receiver 868 has a substantially gate-like shape with an open bottom, and a through-hole 869 penetrating in the lateral direction is formed in the lower part thereof. A part of the connection receiver 868 protrudes downward from a connection groove 853 provided in the recessed part 850, and the through hole 869 is disposed in the protruded part.

  In addition, micro switches (not shown) are respectively installed on the lower surface of the recessed portion 850 at the front end and the rear end of the movement range of the connection receiver 868, and the micro switch operates when the connection receiver 868 abuts. It has a configuration.

FIGS. 12A and 12B show a driving force release mechanism in the driving unit 860. FIG. A driving force release mechanism is provided at the installation portion of the reduction gear 864. 12A is a perspective view of the driving force release mechanism, and FIG. 12B is a diagram of the gear configuration. The driving force release mechanism is a bearing portion of the reduction gear B871 between the two gears in the middle of transmitting the driving force of the DC motor 861 to the screw shaft 865, the reduction gear A870 and the reduction gear B871, as shown in FIG. Relief groove 873
In general, the gear shaft 874 of the reduction gear B871 is biased by a spring 872 in such a direction as to bring the shaft portions close to each other in order to bite the reduction gears. The reduction gear B871 can mesh with the reduction gear A870 and transmit the driving force by the elastic force of the spring 872. When a foreign object bites into the gear during driving or a hand or the like is sandwiched between the main body and the toilet bowl, if a force greater than the elastic force of the spring 872 is applied to the bearing portion, the gear shaft 874 elastically deforms the spring 872. Thus, the gear shaft 874 moves through the escape groove 873 and reaches a position where the driving force is not transmitted. As a result, the meshing of the reduction gear is released and the transmission of the driving force is released, thereby preventing the drive unit 860 and the sliding coupling unit 840 from being damaged.

  On the other hand, as in the first embodiment, a rear engagement piece 831 and a front engagement piece 832 (not shown) are provided on both side surfaces of the recessed portion 850 of the bottom plate 210 at an interval. The rear engagement piece 831 has a substantially semi-cylindrical shape and is disposed at the rear end of the recessed portion 850, and the front engagement piece 832 has a substantially cylindrical shape and is disposed at a substantially horizontal position with respect to the rear engagement piece 831.

  The support portion 710 shown in FIG. 9 has the same configuration as that of the first embodiment, and the planar shape formed of a resin material is substantially U-shaped, and a groove-like slide having open sides on both sides thereof. Guides 801 are provided respectively. The sliding guide 801 has a substantially horizontal flat portion 802 at the rear portion and an inclined portion 803 inclined upward at the front portion, and the flat portion 802 and the inclined portion 803 are smoothly connected with a curve. The rear end of the sliding guide 801 is closed, and the front end is provided with an opening 804 that opens upward.

  In addition, a connecting piece 805 is integrally formed inside the support portion 710, and a substantially U-shaped through hole 806 is provided at a substantially center of the connecting piece 805. A connecting pin 807 that can be inserted into and removed from the through-hole 806 is supported by an operating rod 808 that can be moved to the left and right, and the rear end 809 of the operating rod 808 facing the rear surface of the support portion 710 is moved to the left and right to The pin 807 is inserted into and removed from the through hole 806.

  As shown in FIG. 10, when the main body 200 and the support 710 are coupled, the rear engagement piece 831 and the front engagement piece 832 are inserted from the opening 404 of the sliding guide 801 as in the first embodiment. While pushing the main body 200 backward. The rear end 809 of the operation rod 808 is moved in the direction of arrow A, and the connection pin 807 is opened in the state where the connection pin 807 is opened until the positions of the connection piece 867 of the main body 200 and the connection piece 805 of the support portion 710 match. By returning the rear end portion 809 of 808 in the direction of arrow B, the connection pin 807 is inserted into the through hole 806 of the connection piece 805 and the through hole 868 of the connection receiver 867, and the connection piece 805 and the connection receiver 868 are inserted into the connection piece 805. By being connected, the sliding coupling portion 800 is coupled.

  In the state where the sliding coupling unit 800 is coupled, the worm 862 and the worm gear 863 are employed in the driving unit 860, so that the DC motor 861 directly coupled to the worm 860 does not rotate due to the self-stopping property of the worm gear system. As long as it does not move as much as possible, even if an external force is applied to the main body 200 to move it back and forth, the movement is restricted. That is, the worm 862 and the worm gear 863 serve as a movement restricting means.

  Also, as shown in FIG. 11, a piezoelectric contact sensor 810 is disposed along the outer periphery of the bottom plate 210 of the main body 200. The piezoelectric contact sensor 810 is a wire-like sensor in which two lead wires are arranged in parallel, and a space is usually provided between them. If something comes into contact with this sensor, the distance between the two lines decreases. Thereby, since the electrostatic capacitance of the sensor changes, it is possible to detect the contact of a foreign substance to the piezoelectric contact sensor 810 by detecting the change of the electrostatic capacitance.

<2-2> Operations and Actions of Second Sliding Coupling Unit and Drive Unit When the main body 200 is in the stationary position shown in FIG. A signal is sent from the remote control device 300 to the control unit built in the main body 200, and the control unit first starts controlling the toilet seat toilet lid opening / closing device 900, and the toilet seat unit 400 and the toilet lid unit 500 are both rotated and opened. It becomes a state.

  This operation is performed to reduce the load of the moving operation of the main body, and is particularly effective in reducing the load of the operation of lifting the front portion of the main body 200. The function of lifting the toilet seat device 110 is to lift the front side of the main body 200 by driving the toilet seat main body 200, the toilet seat 400, and the toilet lid 500 back and forth along the sliding guide 801. At this time, the sliding guide 801 generates a moment due to the weight of the main body 200, the toilet seat 400 and the toilet lid 500 with the rear engagement piece 831 as a fulcrum. The drive unit 860 is configured to raise the front portion of the main body 500 against this moment, but the moment increases when the toilet seat 400 and the toilet lid 500 are closed. For this reason, the required driving force is increased, and the components of the driving unit 860, the sliding guide 801, and the front and rear engaging pieces 831 and 832 are required to have high strength.

  Therefore, the moment generated by bringing the toilet seat unit 400 and the toilet lid unit 500 upright by the toilet seat toilet lid opening / closing device 900 brings the lateral center of gravity of the entire toilet seat device 110 closer to the rear engagement piece 831 serving as the rotation center. The weight of the toilet seat device 110 can be reduced by bringing the rear end of the main body 200 into contact with the upper surface of the toilet bowl 200, and the load applied to the rear engagement piece 831 and the front engagement piece 832 can be reduced.

  Further, simultaneously with the start of the pivoting operation of the toilet seat 400 and the toilet lid 500, other operations of the remote control device 300 cannot be performed, and the safety associated with the lift-up operation of the main body 200 is ensured.

  When the toilet seat 400 and the lid 500 are in the open state, the control unit starts controlling the drive unit 860, the DC motor 861 starts driving, and the main body unit 200 starts moving forward.

  As in the first embodiment, the main body 200 first translates forward, and a gap is formed between the rear of the main body 200 and the low tank 720 installed at the rear of the toilet 700. The main body 200 continues to move forward and tilts so that the front part is lifted. As shown in FIG. 8B, when the main body 200 reaches a predetermined ascending position, the connection receiver 868 comes into contact with the microswitch, thereby causing the DC motor 861. Is stopped and the front part is lifted up, and the state shown in FIG. 8B is maintained.

  In this state, a gap is generated between the bottom plate 210 of the main body 200 and the upper surface of the toilet 700, and the bottom plate 210 of the main body 200 and the upper surface of the toilet 700 can be easily cleaned. At this time, particularly the upper end of the rear portion of the main body 200 is inclined rearward, but since the main body 200 first moved forward, interference between the main body 200 and the low tank 720 can be prevented.

  When the toilet seat lift up switch 334 is operated again when the cleaning is completed, the DC motor 861 starts reverse rotation, and the main body 200 moves backward while lowering the front. When the main body part 200 moves to a predetermined stationary position, the DC motor 861 is stopped by the connection receiving tool 868 coming into contact with the microswitch, and the main body part is fixed at the stationary position.

  Next, the toilet seat toilet lid opening / closing device 900 is operated to close the toilet seat 400 and the lid 500, and other operations of the sanitary washing device can be performed.

Further, in the process of moving from the raised position to the stationary position, if there is a foreign object on the upper surface of the toilet bowl 700 or if the user accidentally pinches his / her hand, it is stretched along the outer periphery of the bottom surface 210 of the main body 200. A foreign object or a hand is detected by contacting the piezoelectric contact sensor 810, and the control unit cuts off the energization to the DC motor 861 and stops the driving unit 860 to ensure safety. In addition, it is possible to prevent an excessive force from being applied to the driving unit 860 and the sliding coupling unit 840 to cause breakage or failure.

  In the present embodiment, the piezoelectric contact sensor 810 is used for pinching detection. However, the present invention is not limited to this. For example, a current value applied to the DC motor 861 is measured by a control unit (not shown). Thus, when there is some physical drive resistance, it is possible to detect a change in increase / decrease in the current value applied to the DC motor 861. Accordingly, it is possible to determine whether or not there is an operation resistance such as a foreign object being caught. In this case as well, when a foreign object is detected, the driving of the DC motor 861 is immediately stopped.

  In the present embodiment, the driving force release mechanism employs a configuration in which the reduction gear A870 and the reduction gear B are also released from the engagement by the relief groove 873 of the gear shaft 874 as described above. For example, as shown in FIGS. 13A and 13B, the same effect can be obtained even if a clutch mechanism is used.

  As shown in FIGS. 13A and 13B, there is a configuration in which a clutch plate 875 that transmits power to the reduction gear B871 by frictional force is urged by a compression spring 876. The clutch plate 875 is fixed to the gear shaft 874 and the driving force is transmitted. The reduction gear B871 is coupled to the gear shaft 874 so that it can rotate without being fixed, and the transmission force is transmitted by the friction force generated on the friction surface of the clutch plate 875 and the reduction gear B. In this case, by appropriately selecting the surface roughness and material of the clutch plate 875 and the spring load of the compression spring 876, the necessary driving force can be transmitted while excessive torque that causes the product operation to be stopped artificially. When it occurs in the gear reduction mechanism, the transmission of power can be released by overcoming the frictional force between the clutch plate and the side surface of the gear and sliding the clutch plate.

(Embodiment 3)
The basic configuration of the sanitary washing device 100 in the present embodiment is the same as that in the second embodiment, and the control method during the lift-up operation is different. In particular, in the second embodiment, during the lift-up operation, the toilet seat 400 and the toilet lid 500 are in a sequence that is automatically opened. However, in the present embodiment, the toilet seat 400 and the toilet lid 500 are used. Is opened and closed arbitrarily by the user by operating the toilet seat opening / closing switch 441 and the toilet lid opening / closing switch 442.

  FIG. 17 is a flowchart showing the basic operation during the lift-up operation in the present embodiment.

  When the toilet seat lift up switch 334 is input, the toilet lid angle detection unit 952 determines whether or not the toilet lid portion 500 is open in STEP 100. If the toilet lid 500 is not in the open state, the process proceeds to STEP 103 and the lift-up operation is canceled.

  Similarly, in STEP 101, whether the toilet seat 400 is in the open state is determined by the toilet seat angle detecting means 942, and if the toilet seat 400 is not in the open state, the lift-up operation is canceled in STEP 103.

  When it is detected that both the toilet lid part 500 and the toilet seat part 400 are in the open state, the main body part 200 is moved to the raised position in STEP102. In STEP 104, it is detected whether or not the main body has reached the raised position, and if it has reached, the operation is stopped. In this state, the bottom plate 210 of the main body 200 and the upper surface of the toilet bowl 700 can be easily cleaned.

  In addition, when the toilet seat is closed, the toilet lid is not always closed, but when the toilet seat is open, the toilet lid is opened securely. You can determine whether you are standing. For this reason, the determination as to whether or not to perform the operation can be performed only by determining whether the toilet seat is opened or closed. In addition, when the toilet seat is in an open state, it is possible to prevent an excessive force from being applied to the drive unit in accordance with the lift-up operation of the main body unit 200, thereby ensuring safety.

  Next, FIG. 18 is a flowchart showing an operation when the main body 200 is returned from the raised position to the stationary position.

  After the completion of the cleaning operation or the like, the main body 200 starts to move to the stationary position by operating the toilet seat lift up switch 334 again. As shown in FIG. 18, the main body 200 starts moving to the stationary position in STEP 200 and confirms whether or not it has reached the stationary position in STEP 201, and proceeds to STEP 202 if it has reached. Here, whether or not the toilet seat 400 is in the open state is determined by the toilet seat angle detecting means 942, and if it is in the open state, the toilet seat 400 is closed as in STEP203. Next, similarly, in STEP 204, it is determined by the toilet lid angle detecting means 952 whether or not the toilet lid portion 500 is in the open state. finish.

  By this operation, the toilet seat 400 and the toilet lid 500 are not raised in the closed state as described above, and the probability of leading to product failure can be reduced, and a highly reliable toilet seat device can be provided. it can.

  In FIG. 18, the toilet seat 400 and the toilet lid 500 are all closed and the operation is finished. However, this stores the initial angles at the start of the toilet seat lift-up operation, and only the toilet seat 400 is closed. In such a case, it may be possible to return to the initial state and close the operation, for example, by closing only the toilet seat 400. In this case, there is an advantage that the user's intention can be respected and the toilet seat device 110 can be used in a user's favorite state without changing the state before and after the lift-up operation by an unintended operation.

  As described above, the toilet seat device according to the present invention can facilitate the cleaning of the concealing portion, and thus can be applied to uses such as equipment installed and used.
