Abstract

PURPOSE:To reduce cost by using only one sensor by driving a motor for opening and closing only for a prescribed time in connection with an opening signal of a lavatory seat, and also, actuating the motor in the closing direction by a closing signal, and stopping the motor by a lavatory detecting output of the sensor. CONSTITUTION:The device is constituted so that when a lavatory seat is in a closed position, a shielding plate 50 shuts off the light and a sensor 5 outputs a detecting output. A motor 30 for opening and closing the lavatory is controlled by a control part to which an opening/closing switch and the sensor 5 are connected. Two timers T1, T2 are contained, and when an opening signal is inputted from the switch, the lavatory is opened by rotating the motor 30 by t1. On the other hand, when a closing signal is inputted from the switch, the motor 30 is actuated in the backward direction, started at the time point when the sensor 5 outputs a lavatory seat detecting signal, and the motor 30 is stopped at a time-up point of the timer t2 in which a set time t2 is a minute time (<= one second).

It only needs to detect if the toilet seat has reached the closed position when closing the toilet seat. At this time, if the control unit lowers the motor drive voltage when closing the toilet seat than the drive voltage when opening the toilet seat, it consumes less power, and the motor control by the control unit causes the toilet seat open signal. Along with this, the opening / closing motor is driven at a high voltage for a predetermined time and then at a low voltage for a short time, and at the same time, the motor is started at a high voltage in the toilet seat closing direction by the toilet seat closing signal and the toilet seat detection output by the above sensor is used. If the motor is driven at a low voltage for a short time and then stopped, the movement of the toilet seat can be smoothed.

ーＴ2 のタイムアップ時点でモータ３０を停止させる。A shield plate 50 is attached to the output shaft 38. The shield plate 50 shields light between the light emitting and receiving parts of the sensor 5 composed of a photo interrupter. Here, when the toilet seat 10 is in the closed position, the shield plate 50 shields light and the sensor 5 outputs a detection output. I'm trying to put it out. The motor 30 is controlled by a control unit to which an open / close switch and the sensor 5 are connected. The control unit here has two timers T 1 , T 2
Is built in, and when an open signal is input from the switch,
As shown in FIG. 1A, the toilet seat 10 is opened by rotating the motor 30 in one direction for a predetermined time t 1 . When a closing signal is input from the switch, the motor 10 is started in the opposite direction to the sensor 5 as shown in FIG. 1 (b).
Starts when the toilet seat detection signal is output, and the motor 30 is stopped when the set time t 2 is a minute time (1 second or less) of the timer T 2 .

It may be a single switch. In this case, when the sensor 5 is on when the switch is turned on, the toilet seat 1
To open 0, when the sensor 5 is off, the toilet seat 1
The motor 30 is rotated in the direction of closing 0. When the toilet seat 10 is located at a position other than the closed position, the motor 30 is driven in the direction to close the toilet seat 30, so there is no problem. Further, since the operation of closing the toilet seat 10 has a smaller load than the operation of opening the toilet seat 10, the driving voltage of the motor 30 may be lowered when closing the toilet seat 10, as shown by the chain line in FIG.
Power consumption can be reduced.

Here, a timer T 3 is also provided as a control unit, and when the toilet seat 10 is opened, as shown in FIG. 5A, first, the motor 30 is driven for a predetermined time t 1 and then the timer T 3 is used. By driving the motor 30 at a low voltage for a set minute time t 3 , the operation of the end of opening the toilet seat 10 is made smooth, and when the toilet seat 10 is closed, as shown in FIG. 5 (b). in, that the timer T 2 sensor 5 the driving voltage of the motor 30 in the set minute time timer T 2 t 2 is turned on is lower than the driving voltage until the start, also the operation of the end and closed smoothly I am trying to become.
Even in this case, if the drive voltage of the motor 30 when the toilet seat 10 is closed is set to a low voltage over the entire area as shown by the chain line in FIG. 5B, the power consumption can be reduced.

Further, the motor control by the control unit is performed by the toilet seat open signal. In response to this, the opening / closing motor is driven at a high voltage for a predetermined time and then at a low voltage for a short time, and at the same time, the motor is started at a high voltage in the toilet seat closing direction by a toilet seat closing signal and the toilet seat detection output by the above sensor If the motor is stopped at a low voltage for a short time and then stopped, the movement of the end of opening and the end of closing of the toilet seat can be smoothed.
