Description

  The present invention relates to a sanitary washing apparatus including a seating detection switch that detects a human body seated on a toilet seat.

  Conventionally, a sanitary washing apparatus including a seating detection switch that detects a human body seated on a toilet seat has been proposed (see, for example, Patent Document 1).

  Hereinafter, the sanitary washing device described in Patent Document 1 will be described with reference to FIGS. 15A and 15B.

  FIG. 15A is a cross-sectional view showing a non-sitting state of a seating detection switch of a conventional sanitary washing device. FIG. 15B is a cross-sectional view showing the sitting state.

  As shown in FIGS. 15A and 15B, the conventional sanitary washing device has a vertically long slot 2 disposed on the side surface of the main body 1 fixed to the upper rear portion of the toilet bowl, and the main body 1 facing the long hole 2 A support base 3 of a resin molded product is fixed to the main body 1 inside. A slide receiving portion 4 that supports the movable member 7 so as to be slidable in the vertical direction is formed at the center of the support base 3. A normally closed type micro switch 5 is disposed on the upper side of the support base 3, and a coil spring 6 is provided on the lower side of the support base 3. A movable member 7 is installed between the microswitch 5 and the coil spring 6. Further, a bearing hole 10 is formed in the movable member 7 in the horizontal direction, and a cylindrical rotation shaft 9 provided at the rear end side portion of the toilet seat is rotatably inserted in the bearing hole 10. Yes.

  At this time, as shown in FIG. 15A, the movable member 7 is pushed upward by the elastic force of the coil spring 6 in a non-sitting state where the user is not seated on the toilet seat. Then, the movable member 7 presses the actuator 11 of the micro switch 5, and the contact point of the micro switch 5 is opened.

  On the other hand, as shown in FIG. 15B, in the seated state where the user is seated on the toilet seat, the movable member 7 moves downward against the elastic force of the coil spring 6. At this time, the actuator 11 of the microswitch 5 and the movable member 7 are separated from each other, and the contact of the microswitch 5 is brought into a contact state. As a result, the circuit is energized, a seating detection signal is sent to the control device, and a human body seated on the toilet seat is detected.

  Thereby, in the structure of the conventional sanitary washing device, it is possible to accurately detect the seating and non-sitting of the user in the normal use state in which the toilet seat 8 is inverted on the toilet bowl and the user is seated on the toilet seat 8 It is said.

  However, the movable member 7 moves downward when the toilet seat 8 is pressed from above at all rotational positions in the middle where the toilet seat 8 is not completely inverted. Therefore, the contacts of the microswitch 5 are in contact and a seating detection signal is transmitted to the control device. For example, when the toilet seat 8 is erected, such as when the boy is small, when the toilet seat 8 is pressed from above, the movable member 7 moves downward. Therefore, even when the user is not seated on the toilet seat 8, the contacts of the microswitch 5 come into contact. Then, a seating detection signal is transmitted to the control device, and an erroneous detection that the user is seated on the toilet seat occurs. That is, the configuration of the conventional sanitary washing apparatus still has room for improvement from the viewpoint of detection accuracy for detecting the seating of the user's toilet seat.

As shown in FIG. 4, the toilet seat shaft 310 has a cylindrical support portion 311 at the base portion (toilet seat 300 side portion) of the toilet seat shaft 310, and a substantially semicircular shape (semicircular shape). Operation piece 312 (including shape). The operation piece 312 directly contacts a seating detection switch 500 described later, and has a function of performing an opening / closing operation of the seating detection switch 500.

  As shown in FIGS. 10, 12, and 14, a vertically long bearing hole 111 through which the toilet seat shaft 310 of the toilet seat 300 passes is formed on the right side surface of the main body case 110 of the main body 100. At this time, the dimension of the bearing hole 111 in the front-rear direction is slightly larger than the outer diameter (for example, 17 mm) of the support portion 311 of the toilet seat shaft 310, and the vertical dimension is approximately 2.5 mm larger than the dimension in the front-rear direction. It is formed with dimensions. Therefore, in a state where the support portion 311 of the toilet seat shaft 310 is inserted through the bearing hole 111, the movement of the toilet seat shaft 310 in the front-rear direction is restricted and the vertical movement is configured to be able to move about 2 mm.

  Furthermore, a seating detection switch 500 is fixed to the main body case 110 of the main body 100 and arranged inside the bearing hole 111.

  Next, a detailed configuration of the seating detection switch according to the present embodiment will be described with reference to FIGS.

  As shown in FIG. 5, the seating detection switch 500 according to the present embodiment includes at least a support member 510, a coil spring 520 that constitutes an elastic body, a microswitch 530 that constitutes a switch, a movable member 540, and the like. ing.

  The support member 510 includes, for example, a spring holding portion 512, a spring holding guide 513, a stopper hole 514, and a switch fixing portion 515 formed in a plate-like main body portion 511. The spring holding portion 512 protrudes from the lower end portion of the main body portion 511 in a substantially horizontal direction (including the horizontal direction), and is formed at, for example, two front and rear portions to hold the coil spring 520. The spring holding guide 513 extends upward at the center of the spring holding portion 512 and is formed integrally with the spring holding portion 512. The stopper hole 514 is formed at the center of the support member 510 and restricts the upward movement of the movable member 540. The switch fixing part 515 is formed on the upper part of the main body part 511 and fixes the micro switch 530.

  The movable member 540 is integrally formed with a resin material such as PP (polypropylene), for example, and includes an operation hole 541 formed in the center portion and a slide portion 545. The operation hole 541 is formed by an arc-shaped arc portion 542 and a linear portion 543 formed continuously above the arc portion 542 substantially horizontally (including horizontal). The upper surface of the linear part 543 has a flat operation surface 544 and constitutes the upper surface of the movable member 540.

  The slide portion 545 of the movable member 540 is formed integrally with the both ends of the lower side of the movable member 540 so as to extend in the horizontal direction. A slide hole 546 is formed at substantially the center (including the center) of the slide portion 545. At this time, the shape and size of the slide hole 546 are formed to be slightly larger than the outer diameter of the spring holding guide 513 of the support member 510. Accordingly, the movable member 540 can be smoothly slid and moved in a state where the spring holding guide 513 is inserted into the slide hole 546.

  Further, as shown in FIG. 6, a stopper projection 547 is integrally formed on the back side of the movable member 540. A stopper 501 is configured by the stopper protrusion 547 of the movable member 540 and the stopper hole 514 of the support member 510.

  Specifically, as shown in FIG. 8, the stopper 501 is configured by inserting the stopper protrusion 547 of the movable member 540 into the stopper hole 514 in a state where the seating detection switch 500 is assembled. Accordingly, the stopper protrusion 547 can slide up and down along the stopper hole 514. At this time, the stopper protrusion 547 contacts the upper end portion 501a of the stopper hole 514, thereby restricting the upward movement of the movable member 540. Thereby, it is possible to prevent the micro switch 530 disposed on the upper portion of the support member 510 from being pressed more than necessary by the movable member 540. As a result, damage to the microswitch 530 can be suppressed in advance.

  Further, the coil spring 520 of the seating detection switch 500 is constituted by a compression coil spring made of stainless steel, for example. The inner diameter of the coil of the coil spring 520 is slightly larger than the outer diameter of the spring holding guide 513 of the support member 510.

  Further, the micro switch 530 of the seating detection switch 500 is a normally closed switch, and as shown in FIGS. 11 and 12, the contact point is in a contact state when the push button type operation unit 531 is not pressed. It has become. Then, when the operation unit 531 is pressed, the contact of the micro switch 530 is opened.

  The seating detection switch according to the present embodiment is configured as described above.

  Next, the arrangement relationship and operation of the seating detection switch 500 and the main body 100 in a state in which the support member 510, the coil spring 520, the micro switch 530, and the movable member 540 having the above-described configuration are combined will be described with reference to FIGS. A brief explanation.

  As shown in FIGS. 8 to 12, in the seating detection switch 500, first, coil springs 520 are fitted in the two spring holding guides 513 of the support member 510. A stopper protrusion 547 of the movable member 540 is fitted in the stopper hole 514 of the support member 510 above the coil spring 520. Further, the micro switch 530 is fixed to the switch fixing portion 515 of the support member 510 with the operation portion 531 (see FIG. 11) on the lower side.

  9 and 10, in the state where the toilet seat 300 is installed on the main body 100, the support portion 311 of the toilet seat shaft 310 of the toilet seat 300 penetrates the bearing hole 111 of the main body case 110, and the toilet seat shaft 310 The operation piece 312 is inserted into the operation hole 541 of the movable member 540. When the toilet seat 300 is in the inverted position, the operation piece 312 of the toilet seat shaft 310 is disposed below the operation hole 541 of the movable member 540. At this time, in a state in which no pressure is applied to the toilet seat 300, the movable member 540 is in contact with the lower end portion 541 a of the operation hole 541 of the movable member 540 by the elastic force of the coil spring 520. In this state, it is pushed upward. Further, in the case of the above state, the rear portion of the toilet seat 300 is also lifted from the upper surface 700a of the toilet bowl 700, corresponding to the movable range in the vertical direction of the bearing hole 111, for example, by about 2 mm. At this time, the operation surface 544 of the movable member 540 is in contact with the operation unit 531 (see FIG. 11) of the microswitch 530, and the operation unit 531 is pushed up to open the contact of the microswitch 530.

<4> Operation and Action of Seating Detection Switch Hereinafter, the operation and action of the seating detection switch of the sanitary washing device of the present embodiment will be described in detail with reference to FIGS.

  First, as shown in FIGS. 9 and 10, when the toilet seat 300 is in the inverted position, the movable member 540 is pushed upward by the elastic force of the coil spring 520. At this time, the operation piece 312 of the toilet seat shaft 310 is in contact with the lower end 541 a of the operation hole 541 of the movable member 540. The operation piece 312 of the toilet seat shaft 310 is maintained in a state of being pushed upward in conjunction with the movable member 540. In this state, together with the movable member 540, the toilet seat shaft 310 of the toilet seat 300 is also pushed upward. As a result, as shown in FIG. 10, a movable space D <b> 1 of about 2 mm is formed between the lower surface 311 a of the support portion 311 of the toilet seat shaft 310 and the lower end portion 111 a of the bearing hole 111 of the main body case 110. And the rear part of the toilet seat 300 is also held in a state of being slightly lifted from the upper surface 700a of the toilet bowl 700.

  At this time, the operation surface 544 of the movable member 540 is in a state where the operation unit 531 of the micro switch 530 is pressed. Thereby, the contact state of the micro switch 530 is maintained in an open state. Therefore, the seating detection signal is not transmitted from the micro switch 530 of the seating detection switch 500 to the control unit.

  On the other hand, as shown in FIGS. 11 and 12, when the user is seated on the seating surface 301 of the toilet seat 300, the rear portion of the toilet seat 300 is pushed down by the weight of the user. At this time, the operation piece 312 of the toilet seat shaft 310 moves downward, and the movable member 540 moves downward in conjunction with the operation piece 312. Then, the operation surface 544 of the movable member 540 is separated from the lower surface 531a of the operation unit 531 of the micro switch 530. Thereby, the contact of the micro switch 530 is brought into a contact state. As a result, a seating detection signal is transmitted from the micro switch 530 of the seating detection switch 500 to the control unit, and the seating of the user is detected.

  At this time, as shown in FIGS. 11 and 12, when the operation surface 544 of the movable member 540 and the operation portion 531 of the micro switch 530 are separated from each other, the distance between the operation surface 544 and the lower surface 531a of the operation portion 531 is about A gap D2 of 1 mm is formed. The gap D2 is maintained while the user is seated on the toilet seat 300. Therefore, when the user moves his / her body while sitting, even if some vertical movement occurs in the toilet seat 300, the operation unit 531 of the micro switch 530 is prevented from being pressed by the operation surface 544 of the movable member 540. it can. Thereby, the interruption of the seating detection signal due to the opening of the contact of the micro switch 530 can be prevented. As a result, it is possible to prevent an unintended stop during the cleaning operation.

  On the other hand, when the toilet seat 300 is rotated from the inverted position to the standing position, the operation piece 312 of the toilet seat shaft 310 moves toward the upper portion of the operation hole 541 of the movable member 540 during the rotation. Along with this, the toilet seat 300 moves below the operation hole 541 of the movable member 540 by its own weight. As shown in FIG. 14, the support portion 311 of the toilet seat shaft 310 contacts the lower end portion 111 a of the bearing hole 111.
