In this example, the case 81 has a first case member 81a and a second case member 81b. A cylindrical case 81 is formed by combining the first case member 81a and the second case member 81b. As described above, the case 81 may be a combination of a plurality of members, or may be formed from a single member. The case 81 is fixed to the casing 10 by any fixing means such as screws and bolts.

The motor 82 is housed in the case 81 . More specifically, at least part of the motor 82 is housed in the first case member 81a, and the rotating shaft 82a of the motor 82 protrudes toward the second case member 81b.

The transmission mechanism 83 is housed in the second case member 81 b of the case 81 . The transmission mechanism 83 is connected to the rotating shaft 82 a of the motor 82 and directly or indirectly transmits the rotation of the motor 82 to the output shaft 85 . In this example, the rotation of motor 82 is transmitted to output shaft 85 via shaft portion 84 .

The transmission mechanism 83 is, for example, a speed reduction mechanism, which is a planetary gear mechanism in this example. More specifically, in this example, the transmission mechanism 83 includes a sun gear 83a, a planetary gear 83b, a planetary carrier 83c (sun gear), a planetary gear 83d, a planetary carrier 83e (sun gear), and a planetary gear. 83f, a planetary carrier 83g and an internal gear 83h.

The internal gear 83h has a cylindrical shape and has teeth on its inner peripheral surface that engage with the planetary gears 83b, 83d, and 83f. In this example, the internal gear 83h is relatively fixed to the case 81, and is a member that does not rotate even if the output shaft 85 is rotated by the rotating shaft 82a of the motor 82.

The sun gear 83a is connected to the rotating shaft 82a of the motor 82 and rotates around the rotating shaft 82a.
The planetary gear 83b is engaged with the sun gear 83a, and revolves and rotates around the sun gear 83a as the sun gear 83a rotates.
The planetary carrier 83c is engaged with the planetary gear 83b and rotates along with the rotation of the planetary gear 83b.
The planetary carrier 83c is a sun gear that engages with the planetary gear 83d. The planetary gear 83d revolves and rotates around the planetary carrier 83c as the planetary carrier 83c rotates.
The planetary carrier 83e is engaged with the planetary gear 83d and rotates along with the rotation of the planetary gear 83d.
The planetary carrier 83e is a sun gear that engages with the planetary gear 83f. The planetary gear 83f revolves and rotates around the planetary carrier 83e as the planetary carrier 83e rotates.
The planetary carrier 83g is engaged with the planetary gear 83f and rotates along with the rotation of the planetary gear 83f.

The shaft portion 84 is accommodated in the second case member 81b of the case 81 and is directly or indirectly connected to the planetary carrier 83g. The shaft portion 84 rotates as the planetary carrier 83g rotates. The shaft portion 84 may be provided with a torque limiter, for example.

At least a portion of the output shaft 85 protrudes from the case 81 . In this example, one end of the output shaft 85 protrudes from the second case member 81b, and the other end of the output shaft 85 is housed in the second case member 81b and connected to the shaft portion 84. The output shaft 85 is rotatable with respect to the case 81 as the rotary shaft 82a of the motor 82 rotates. As a result, the output shaft 85 outputs the rotational force of the motor 82 transmitted via the transmission mechanism 83 to the toilet seat 30 or the toilet lid 50 . That is, the electric opening/closing unit 80 opens/closes the toilet seat 30 or the toilet lid 50 by the rotation of the motor 82 transmitted to the output shaft 85 .

The spring 86 is housed in the second case member 81b of the case 81. As shown in FIG. Spring 86 is, for example, a torsion coil spring. One end of the spring 86 is connected to the transmission mechanism 83 and the other end of the spring 86 is connected to the output shaft 85 . A spring 86 biases the output shaft 85 in the rotational direction of the output shaft 85 . That is, the elastic force of spring 86 is transmitted to toilet seat 30 or toilet lid 50 via output shaft 85 . For example, spring 86 biases toilet seat 30 or toilet lid 50 in an open direction. By providing the spring 86, the opening and closing of the toilet seat 30 and the toilet lid 50 can be assisted.

A shaft portion 84 is arranged inside the spring 86 . For example, the rotation shaft 82a of the motor 82, each planetary carrier (each sun gear) of the transmission mechanism 83, the shaft portion 84, the output shaft 85, and each central axis (rotational shaft) of the spring 86 are arranged so as to coincide with each other. there is The alignment of the central axes (rotating axes) includes not only cases where the central axes are strictly aligned, but also cases where they are slightly deviated due to manufacturing variations or design play. It's okay. The spring 86 is arranged, for example, so as not to contact the member outside the spring 86 (the case 81) or the member inside the spring 86 (the shaft portion 84).

The open/close detection mechanism 90 detects the open/close state of at least one of the toilet seat 30 and the toilet lid 50 . The open/close detection mechanism 90 detects rotation of the motor 82, for example. The open/close detection mechanism 90 detects, for example, the rotation angle of the output shaft 85 . The opening/closing detection mechanism 90 is electrically connected to, for example, a control circuit (control section 20 described later) that controls the operation of the electric opening/closing unit 80 . The open/close detection mechanism 90 outputs detection results (for example, the rotation of the motor 82 and the rotation angle of the output shaft 85) to the control circuit (control unit 20). The control circuit (control section 20) controls the operation of the electric opening/closing unit 80 based on the detection result.

The open/close detection mechanism 90 has a rotation detection portion 91 , an angle detection portion 92 , a first harness 93 and a second harness 94 . The rotation detector 91 detects rotation of the motor 82 . The rotation detector 91 detects, for example, whether the motor 82 is rotating. The rotation detector 91 detects, for example, the rotation speed of the motor 82 . The angle detector 92 detects the rotation angle of the output shaft 85 . The first harness 93 is connected to the rotation detector 91 . A second harness 94 is connected to the angle detector 92 .

By separately providing the rotation detection unit 91 and the angle detection unit 92, the open/closed states of the toilet seat 30 and the toilet lid 50 can be detected more accurately. In the embodiment, the open/close detection mechanism 90 may detect the open/close state of the toilet seat 30 and the toilet lid 50 with one sensor. In this case, the open/close detection mechanism 90 may include, for example, a potentiometer.

The rotation detection unit 91 has, for example, a first sensor unit 91a and a first substrate 91b. The first sensor portion 91a detects rotation of the motor 82 . The first sensor unit 91a is, for example, a rotary encoder. The first sensor unit 91a is, for example, a magnetic rotary encoder such as a Hall IC. The first sensor unit 91a may be, for example, a photoelectric rotary encoder such as a photointerrupter. The first substrate 91b is connected to the first sensor section 91a. The first harness 93 is connected to the first board 91b. The rotation detection unit 91 outputs the detection result of the rotation of the motor 82 detected by the first sensor unit 91 a to the control circuit (control unit 20 ) via the first harness 93 .

The angle detection section 92 has a second sensor section 92a and a second substrate 92b. The second sensor portion 92 a detects the rotation angle of the output shaft 85 . The second sensor section 92a is, for example, a rotary encoder. The second sensor unit 92a is, for example, a magnetic rotary encoder such as a Hall IC. The second sensor unit 92a may be, for example, a photoelectric rotary encoder such as a photointerrupter. The second substrate 92b is connected to the second sensor section 92a. The second harness 94 is connected to the second board 92b. The angle detection section 92 outputs the detection result of the rotation angle of the output shaft 85 detected by the second sensor section 92 a to the control circuit (control section 20 ) via the second harness 94 .

At least part of the open/close detection mechanism 90 is provided outside the case 81 . At least part of the rotation detector 91 is provided outside the case 81, for example. In this example, the first sensor section 91 a and the first substrate 91 b are provided outside the case 81 . More specifically, in this example, the case 81 has an external portion 81p provided outside the first case member 81a. A portion of the first substrate 91b is provided on the external portion 81p. Also, the first harness 93 is provided outside the case 81 .

At least part of the angle detection unit 92 is provided outside the case 81, for example. In this example, the second board 92b is provided outside the case 81 . The second sensor portion 92a is provided in a window portion 81w provided in the second case member 81b. The window portion 81w is a hole passing through the second case member 81b. Also, the second harness 94 is provided outside the case 81 .

As a result, the case 81 can be miniaturized, and the electric opening/closing unit 80 can be miniaturized. Further, by providing at least part of the opening/closing detection mechanism 90 outside the case 81 , compared to the case where the opening/closing detection mechanism 90 is provided inside the case 81 , workability in assembling the electric opening/closing unit 80 can be improved.

Further, by providing at least a portion of the rotation detection portion 91 and at least a portion of the angle detection portion 92 outside the case 81, even when the rotation detection portion 91 and the angle detection portion 92 are provided separately, the electric opening/closing unit can be operated. 80 can be made smaller, and workability in assembling the electric opening/closing unit 80 can be improved. In particular, by providing the control board (for example, the first board 91b and the second board 92b) of the opening/closing detection mechanism 90 outside the case 81, the electric opening/closing unit 80 can be made more compact, and the assembly of the electric opening/closing unit 80 can be simplified. Workability can be further improved.

Further, by providing the first harness 93 and the second harness 94 outside the case 81 , the first harness 93 and the second harness 94 can move the transmission mechanism 83 and the like without providing a large space inside the case 81 . Contact with parts can be suppressed. As a result, the electric opening/closing unit 80 can be miniaturized, and the workability of assembling the electric opening/closing unit 80 can be improved.

At least part of the rotation detector 91 is provided on the side opposite to the output shaft 85 with respect to the motor 82 . More specifically, the first sensor portion 91a is provided on the side opposite to the output shaft 85 with respect to the motor 82, for example. In other words, the motor 82 is provided, for example, between the first sensor portion 91a and the output shaft 85 in the axial direction.

Also, a portion of the first substrate 91b is provided on the side opposite to the output shaft 85 with respect to the motor 82, for example. In this example, a portion of the first substrate 91b is provided between the first sensor section 91a and the motor 82 in the axial direction. In this example, another part of the first substrate 91b is provided outside the motor 82 in the radial direction. Here, the “radial direction” is the radial direction of a circle centered on the rotating shaft of the motor 82 . That is, the direction (radial direction) connecting the other part of the first substrate 91b and the motor 82 is orthogonal to the direction along the rotation shaft of the motor 82 (axial direction).

By providing at least a portion of the rotation detection unit 91 on the side opposite to the output shaft 85 with respect to the motor 82 , compared to the case where the rotation detection unit 91 is provided on the same side as the output shaft 85 with respect to the motor 82 , Assembly of the opening/closing unit 80 is facilitated. As a result, workability in assembling the electric opening/closing unit 80 can be improved. Further, by providing the rotation detector 91 at such a position, the rotation of the motor 82 can be directly detected.

At least part of the angle detector 92 is provided radially outside the output shaft 85 . More specifically, the second sensor portion 92a is provided radially outward of the output shaft 85, for example. Here, the “radial direction” is the radial direction of a circle centered on the rotation axis of the output shaft 85 . That is, the direction (radial direction) connecting the second sensor portion 92 a and the output shaft 85 is perpendicular to the direction (axial direction) along the rotation axis of the output shaft 85 . Further, the second substrate 92b is provided, for example, outside the output shaft 85 in the radial direction. That is, the direction (radial direction) connecting the second substrate 92b and the output shaft 85 is orthogonal to the direction (axial direction) along the rotation axis of the output shaft 85 .

The casing 10 covers, for example, the upper side of the toilet seat opening/closing unit 80a and the upper side of the toilet lid opening/closing unit 80b. The casing 10 is positioned, for example, above the rotation detection unit 91 of the toilet seat opening/closing unit 80a, above the angle detection unit 92 of the toilet seat opening/closing unit 80a, above the rotation detection unit 91 of the toilet lid opening/closing unit 80b, and above the toilet lid opening/closing unit 80b. The upper side of the angle detection part 92 is covered.

Since the casing 10 covers the upper side of the electric opening/closing unit 80 , even if at least part of the opening/closing detection mechanism 90 is provided outside the case 81 , the opening/closing detection mechanism 90 can be prevented from being exposed to water.

More specifically, the rotation detection section 91 of the toilet seat opening/closing unit 80a outputs the detection result to the control section 20 via the first harness 93a. The angle detection section 92 of the toilet seat opening/closing unit 80a outputs the detection result to the control section 20 via the second harness 94a. The rotation detection section 91 of the toilet lid opening/closing unit 80b outputs the detection result to the control section 20 via the first harness 93b. The angle detection section 92 of the toilet lid opening/closing unit 80b outputs the detection result to the control section 20 via the second harness 94b.
