DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing device capable of automatically opening and closing a toilet lid and a toilet seat.

[0002]

2. Description of the Related Art Conventionally, in a device for automatically opening and closing a toilet lid and a toilet seat, a gear is connected to the shafts of the toilet lid and the toilet seat,
The rotation of the motor is decelerated via gears and transmitted to the toilet lid and toilet seat shafts.When the user tries to open and close the toilet lid or toilet seat by hand, the gears are heavy and must be opened and closed manually. There was a problem that it was difficult.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above problems of the prior art, and does not provide a toilet lid, a toilet lid that can easily open and close the toilet seat, and an automatic opening and closing device for the toilet seat. The purpose is to provide a device capable of automatically opening and closing a toilet lid and a toilet seat via a power transmission path connected to a motor, in which a clutch is disposed in the power transmission path and the toilet lid or the toilet seat is a toilet user. A control circuit is provided for opening the clutch when it is detected by the sensor that it has been slightly moved by the hand.

[0004]

[Function] When the toilet user slightly moves the toilet lid or the seat by hand, the clutch is opened through the control circuit to cut off the power transmission path of the gear system, and the toilet lid or the seat is lightly opened and closed by hand. Will be able to.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of a toilet bowl equipped with a toilet lid and a toilet seat automatic opening / closing device. A toilet seat box 2 is fixedly installed on the upper rear surface of the toilet body 1, and is supported by the toilet seat box 2 to open and close. A toilet seat 3 and a toilet lid 4 are provided as possible, and a low tank 5 is provided upright behind the toilet seat box 2. Further, a human body detection sensor 6 capable of detecting that a person stands in front of the toilet body 1 is provided on the side of the toilet seat box 2, and a state in which the toilet user is seated on the toilet seat 3 A seating sensor 7 for detecting the The toilet bowl can be operated by a remote controller 9 mounted on the wall surface of the toilet or the like, and a signal light emitting section 9a is provided below the remote controller 9.

An outline of the automatic opening / closing device portion of such a toilet bowl will be described with reference to a schematic side view of FIG. 2 and a schematic front view of FIG. A control circuit 10 is provided in the toilet seat box 2.
The control circuit 10 is provided with a motor 11
Are connected, and the motor 11 is connected to the first gear 12 and the second gear 13. A clutch 14 is attached to the inside of the second gear 13, and the shaft 15 of the toilet lid 4 is connected to the clutch 14. This clutch 14
Is also connected to the control circuit 10. Further, the toilet seat box 2 is provided with a detection sensor for detecting the open / closed state of the toilet lid 4, an open position sensor 18 for detecting the opened state of the toilet lid 4, and a closed position for detecting the closed state of the toilet lid 4. A sensor 16 is provided, and an intermediate position sensor 17 that detects an intermediate position is provided between the open position sensor 18 and the closed position sensor 16. A detected body 19 that rotates together with the toilet lid 4 is provided on the side of the toilet lid 4. The detected body 19 is made of, for example, a magnetic material, and the sensors 16, 17, and 18 are magnetically coupled. If it is used as a sensor, the open / closed position of the toilet lid 4 can be satisfactorily detected in a state where the detected object 19 reaches the corresponding positions of the sensors 16, 17, and 18.

A block diagram of the control system is shown in FIG. That is, the control circuit 10 receives signals from the human body detection sensor 6 as well as the position sensors 16, 1
The signals from 7 and 18 are input respectively, and the control circuit 10 is connected to a toilet lid opening / closing motor drive circuit 20 for supplying drive power to the toilet lid opening / closing motor 11. Further, a clutch opening drive circuit 21 that supplies electric power for opening the clutch 14 is connected to the control circuit 10. In addition, although the opening / closing device of the toilet lid 4 is illustrated in this example, the toilet seat 3 also includes the same constituent members, and the toilet seat 3 can be opened and closed separately from the toilet lid 4.

[0008] With the automatic switch in the remote controller 9 turned on, when a toilet user stands in front of the toilet body 1,
The human body detection sensor 6 detects this state and outputs a signal to the control circuit 10. The control circuit 10 outputs a signal to the toilet lid opening / closing motor drive circuit 20, and the toilet lid opening / closing motor drive circuit 20 opens / closes the toilet lid. The electric power is supplied to the motor 11 for rotation, and the motor 11 is rotated. The rotational force is transmitted to the shaft 15 via the clutch 14 via the gears 12 and 13, and the toilet lid 4 is controlled to open automatically. In such a control state, when the toilet user tries to open and close the toilet lid 4 by hand, for example, when the toilet lid 4 is in an open state and the toilet lid 4 is to be manually closed from this state, , The open position sensor 18
On the other hand, since the detected body 19 moves slightly together with the toilet lid 4,
A signal is sent from the open position sensor 18 to the control circuit 10, at which time the control circuit 10 outputs a signal to the clutch opening drive circuit 21, and the clutch opening drive circuit 21 supplies electric power to the clutch 14 to open the clutch 14. Let Clutch 14
When the door is opened, the connection between the shaft 15 of the toilet lid 4 and the gears 12, 13 is cut off, so that the toilet lid 4 can be lightly moved downward.

On the contrary, when the toilet lid 4 is manually opened from the closed position of the toilet lid 4, the closed position sensor 16 similarly informs the control circuit 10 of the state, and the control circuit 10 drives the clutch opening. The signal is output to the circuit 21 and the clutch 14
Then, the toilet lid 4 can be manually opened with a light force. In order to prevent the toilet lid 4 from dropping suddenly when the toilet lid 4 is manually closed from the open state, the toilet cover 4 reaches the position of the intermediate position sensor 17 in the intermediate position. A signal can be sent from the sensor 17 to the control circuit 10, and at this time, the clutch 14 can be engaged via the control circuit 10 to control the toilet lid 4 to slowly rotate downward. It should be noted that the toilet seat 3 can also be configured so that the toilet seat 3 can be manually opened and closed with a light force by similar control.

[0010]

The present invention is an apparatus capable of automatically opening and closing a toilet lid and a toilet seat via a power transmission path connected to a motor, in which a clutch is disposed in the power transmission path and the toilet lid or the seat is used. By providing a control circuit for opening the clutch when it is detected by the sensor that the toilet is slightly moved by the hand of the toilet, the control circuit is provided when the toilet user tries to open or close the toilet lid or the seat by hand. Since the clutch is opened via the power transmission path and the connection with the power transmission path is released, there is an effect that the toilet lid or the toilet seat can be favorably opened and closed with a light force.
