Abstract

PROBLEM TO BE SOLVED: To restrain impact by a stool seat and a stool cover at manually closing time by closing the stool seat and the stool cover by a closing sequence from a prescribed angle when an angle detector detects that the stool seat and the stool cover rotate in the closing direction when the stool seat and the stool cover are not driven by a motor. SOLUTION: A motor 11 is rotated by a signal from the control part 10, and when the rotation is transmitted to a stool seat (and/or a stool cover) 14 through a transmitting means 12, the stool seat 14 rotates in the opening direction or the closing direction. In a standby state, the control part 10 drives/ closes the stool seat 14 by a closing sequence from a prescribed angle when the stool seat 14 rotates in the closing direction by a signal from an angle detecting means 13. However, when the stool seat 14 is forcibly closed, impact force is applied to the transmitting means 12 and the hinge part of the stool seat 14. Thus, a speed is calculated by the control part 10 on the basis of a signal of the angle detecting means 13 to drive the stool seat 14 by the closing sequence corresponding to the speed to be closed so as not to apply impact.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat / closure lid opening / closing device, and more particularly to a control method suitable for a manual closing operation.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a warm water flush toilet seat which opens and closes a toilet seat and / or a toilet lid via a transmission means for reducing the power of a motor. As an automatic opening / closing device for preventing the toilet seat and / or the lid from closing suddenly when manually closed, there is, for example, JP-A-6-142006. A sensor is provided at an intermediate portion from the open end to the closed end, and ON / OFF control of the clutch is performed based on a signal from the sensor.

[0003]

According to the conventional on-off control of the clutch by a sensor provided at the intermediate portion, when a cover is attached to the toilet seat and / or the lid, the load torque increases and the closing speed decreases. There is a problem that it becomes faster and makes a hammering sound and damages a toilet seat / lid and toilet. Conversely, if the load is set with the cover attached to the toilet seat and / or the lid, there is a problem that the load cannot be closed without the cover.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an automatic opening / closing device for a toilet seat and a lid which suppresses an impact caused by the toilet seat and the lid when manually closed. is there.

[0005]

To achieve the above object, the present invention provides a driving motor for opening / closing a toilet seat and / or a lid, and a driving motor for driving the toilet seat and / or the lid to the toilet seat. A transmission means for transmitting power at a reduced speed, and a path from the output shaft of the drive motor to the toilet seat and / or the toilet lid via the transmission means, and an opening / closing angle of the toilet seat and / or the lid. And a control unit for controlling the drive motor, and when the toilet seat and / or the lid are not driven by the motor, the signal of the angle detector outputs the signal from the toilet seat and / or the toilet. When detecting that the lid has turned in the closing direction, the control unit closes the toilet seat and / or the toilet lid in a closing sequence from a predetermined angle.

According to the toilet seat and toilet lid automatic opening and closing device of the first invention, when the motor is not driven, it is detected that the toilet seat and / or the toilet lid has been turned in the closing direction, and the toilet seat is opened. And / or the toilet lid can be driven by a closing sequence. Thereby, it is possible to prevent the toilet seat and / or the lid from colliding with the toilet or the toilet seat at a high speed,
The toilet bowl, the toilet seat and the lid can be prevented from being damaged, and unpleasant collision sound can be prevented.

[0007] The predetermined angle is provided within the operating range of the toilet seat and / or the lid, and may be the same as an angle for detecting that the toilet seat and / or the lid is rotated, or may be equal to or less than the angle. It may be an angle.

As the open / close detecting means for detecting the open / closed state of the toilet lid, limit switches, reed switches, rotary encoders, Hall ICs, MR elements, potentiometers and the like are used.

In the closing sequence, the speed may be gradually reduced so as to be substantially zero at the closing position,
It may be a constant low speed. In the case of a stepping motor whose rotation can be stopped by non-rotational excitation,
Non-rotational excitation ON-OFF may be switched.

According to a second aspect of the present invention, the control unit calculates the closing speed of the toilet seat and / or the lid according to a signal from the angle detector, and executes the closing sequence from the closing speed at a predetermined angle according to the closing sequence. Was configured to be closed.

According to the toilet seat and toilet lid automatic opening / closing device of the second invention, the closing speed can be calculated manually, so that it is possible to create a closing sequence in consideration of the speed.

According to the second aspect of the present invention, the toilet seat and / or the toilet lid can be closed without a sudden change in speed even if the closing speed changes due to the presence or absence of toiletries. And / or to prevent the hinge portion of the stool lid from being damaged by an impact.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further clarify the configuration and operation of the present invention described above, preferred embodiments of the present invention will be described below. FIG. 1 is a block diagram of the toilet seat and toilet lid automatic opening / closing device, FIG. 2 is an overall view of a hot water flush toilet seat incorporating the toilet seat and toilet lid automatic opening / closing device, and FIG. 3 is a closing sequence.

As shown in FIG. 1, the toilet seat and / or the toilet lid 14 is rotated by the motor 11 clockwise or counterclockwise in response to a signal from the control unit 10, and is transmitted through the transmission means 12. 14 to rotate the toilet seat and / or the lid 14 in the opening direction or the closing direction.

In a state where the motor is not rotating, that is, in a standby state, when the toilet seat and / or the toilet lid 14 is rotated in the closing direction by a signal from the open / close detecting means 13, the control unit 10 sets a predetermined angle. By the closing sequence 40 shown in FIG.
The toilet seat and / or the lid 14 are driven to close.

However, when the toilet seat and / or the lid 14 are covered or closed vigorously, the angle-velocity diagram 41 at the time of manual closing changes, so that the drive is started in the closing sequence 40. Occasionally, the speed difference becomes large, and an impact force is applied to the transmission means 12 and the hinge portion of the toilet seat and / or the toilet lid 14. Therefore, the speed at the time of manual closing of a predetermined angle is calculated by the microcomputer of the control unit 10 based on the signal of the angle detecting means 13 and the toilet seat and / or the lid 14 are driven by a closing sequence corresponding to the speed. For example, the transmission means 12 and the hinge portion of the toilet seat and / or the toilet lid 14 can be closed so as not to give an impact.
