とができる。In the electric toilet seat thus formed, the toilet seat 2
When opening and closing, the open / close operation switch 22 provided in the drive box 8 is turned on, and the motor 3 is rotationally driven by a signal from the motor control unit. At this time, when the opening / closing angle sensor detects that the toilet seat 2 is in the position shown by the solid line in FIG. 1 (a), the motor control unit operates to rotate the motor 3 in the normal rotation direction and the motor 3 operates. The motor control section operates so that the voltage of the supplied current is set to the rated voltage of the motor 3, and the electromagnetic control coil 17 is turned on by the clutch control section, and the iron core 21 of the electromagnetic coil 17 is turned on.
The rotary plate 19 rotates against the spring 20 to press the rotary shaft 12 so as to be adsorbed on the rotary shaft 12 and slides the gear 11 e against the spring 14 c to the clutch plate 14 a and the clutch plate 14 a.
b is engaged, the clutch 16 is engaged, and the rotational drive force of the motor 3 is transmitted to the drive shaft 9. In this way, the motor 3 is driven high speed by a high voltage, turning further rotational driving force of the motor 3 is transmitted to the drive shaft 9 while being decelerated by the gear 11 a to 11 g, the toilet seat 2 upward at a faster rate Driven. When the the seat 2 until the theta 1 of the angle of the first view of the immediately preceding (a) the seat 2 is fully opened is rotated is detected by the action of the opening and closing angle sensor, as shown in FIG. 2 (a) The voltage of the current supplied to the motor 3 is
The motor control unit operates so that the voltage becomes lower than the rated voltage of, and the rotation speed of the motor 3 becomes slow. Therefore, the rotation speed of the toilet seat 2 is also slowed down, and the toilet seat 2 comes into loose contact with the low tank 23 and is in a fully opened state. When the opening / closing angle sensor detects that the toilet seat 2 has been rotated up to the angle θ in FIG. 1 (a) in which the toilet seat 2 is in full contact with the low tank 23, the energization of the motor 3 is stopped. As described above, the motor control section operates, and the clutch control section operates so as to stop the energization of the electromagnetic coil 17. When the energization of the electromagnetic coil 17 is stopped in this way, the attraction to the iron core 21 is released and the spring 2
Rotating plate 19 by the action of 0 is rotated, is released presses the rotary shaft 12 the clutch plate 14 a, 14 b meshing of the spring 14
The clutch 16 is disengaged by the action of c , and the rotational driving force of the motor 3 is not transmitted to the drive shaft 9. Therefore, even if the motor 3 continues to rotate by inertia even after the energization is stopped, this rotational force does not act as a force for rotating the toilet seat 2, and it is possible to prevent an unreasonable force from acting on the toilet seat 2. .

の伝達が切れると共にモータ３の回転が停止される。Further, when the opening / closing operation switch 22 is turned on, if it is detected that the toilet seat 2 is at the solid line position in FIG. 1 (b) by the action of the opening / closing angle sensor, the motor 3 is rotationally driven in the reverse direction. The motor control section operates, the motor control section operates so that the voltage of the current supplied to the motor 3 is set to the rated voltage of the motor 3, and the clutch control section operates to turn on the electromagnetic coil 17 and the clutch 16 Then, the rotational drive force of the motor 3 is transmitted to the drive shaft 9. In this way, the motor 3 is rotationally driven at high speed by the high voltage, and the toilet seat 2 is rotationally driven downward at a high speed.
When the opening / closing angle sensor detects that the toilet seat 2 has been rotated up to the angle θ 2 in FIG. 1 (b) immediately before the toilet seat 1 is fully closed, it is shown in FIG. 2 (b). As described above, the motor control unit operates so that the voltage of the current supplied to the motor 3 becomes lower than the rated voltage of the motor 3, and the rotation speed of the motor 3 becomes slow. Therefore, the rotation speed of the toilet seat 2 is also slowed down, and the toilet seat 2
Comes into close contact with the toilet bowl 1 in a fully closed state. When the opening / closing angle sensor detects that the toilet seat 2 has been rotated up to the angle θ in FIG. 1 (b) in which the toilet seat 1 is fully opened and fully opened, the power supply to the motor 3 is stopped. As described above, the motor control section operates, and the clutch control section operates so as to stop the energization of the electromagnetic coil 17, so that the transmission between the motor 3 and the toilet seat 2 is cut off and the rotation of the motor 3 is stopped.

Since it is controlled, the rotation speed of the motor becomes slower and the rotation speed of the toilet seat becomes slower immediately before the toilet seat is fully opened or just before it is fully closed. It can be made smaller, and the rotation speed of the toilet seat slows down only immediately before the fully open or fully closed state,
The time required to open and close the toilet seat does not become long. Moreover, the power supply voltage to the motor is controlled to be lowered to a low voltage without reversing the rotation direction of the motor. Therefore, in order to slow down the rotation speed of the toilet seat, it suffices to reduce the power supply voltage. Therefore, it is not necessary to strictly adjust the power supply voltage, and the power supply voltage can be easily adjusted.
