Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that when a toilet seat or a toilet cover in a conventional toilet bowl is closed, a closing speed is minimized to near zero immediately before a closed position, for prevention of occurrences of collision noises or damages of the seat or cover by the collision, which causes a stop phenomenon (so-called floating) due to foreign matters or the like immediately before a closed position of the seat or the cover, by a simple means. <P>SOLUTION: In the toilet bowl apparatus where the seat 3 or the cover 4 is turned upward to open, after a timer, a sensor or the like recognizes the finish of closing of the seat 3 or the cover 4, a motor applies a force to the seat 3 or the cover 4 in a short time in a closing direction. The force is applied again in the closing direction after the finish of closing of the seat 3 or the cover 4 is recognized. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a toilet device in which a toilet seat or a toilet lid is closed with certainty. More specifically, the toilet seat or the toilet lid can be reliably closed even when the toilet seat or the toilet lid is deformed and cannot be closed reliably by its own weight, or even when the closing angle detection is inaccurate in the electric closing operation. It is about.

Conventionally, a toilet device in which a toilet seat or a toilet lid performs a closing operation with its own weight while applying a brake is known. Specifically, a sensor is provided between the open state and the closed state to detect the closing speed and operate the clutch. There is also known a toilet device that electrically closes and closes the toilet seat or toilet lid manually. Specifically, as shown in Patent Document 1, when the control unit detects that the toilet seat or the toilet lid is rotated in the closing direction, the toilet seat or the toilet lid is closed in a closing sequence from a predetermined angle.
JP 2000-41898 A (Claim 1), (FIG. 3)

  When the toilet seat or toilet lid closes with its own weight while applying a brake, the toilet seat or toilet lid is closed with its own weight, so the toilet seat or toilet lid is not closed with certain deformation or foreign matter. And the toilet seat or toilet lid was in a floating state, and the appearance was poor, and when sitting on the toilet seat, the toilet seat was lowered one step and the feeling of use was not good.

  Even in the toilet device shown in Patent Document 1, the toilet seat or the lid of the toilet needs to be closed at a speed close to zero immediately before the closing position in order to prevent sound generation and damage due to a collision with the toilet. There is a possibility that an error may occur in detection, or it may not be reliably closed due to slight deformation or foreign matter, and the toilet seat or toilet lid is in a floating state.

  The present invention eliminates the influence of slight deformation and foreign matter by applying an external force for a short time in the closing direction after the toilet seat or toilet lid is recognized to be closed, and the toilet seat or toilet lid is securely closed. A device is provided.

  In order to solve the above-described problems, a toilet device according to the present invention is a toilet device according to the first aspect of the present invention, wherein the toilet seat or toilet lid that is pivoted upward and opened is closed. After the completion of the closing operation is recognized by a timer or a sensor, an external force is applied to the toilet seat or toilet lid for a short time in the closing operation direction by a motor.

  The toilet device according to claim 1 reliably closes the toilet seat or the toilet lid in order to apply an external force in a closing operation direction to the toilet seat or the toilet lid by a motor after the toilet seat or the toilet lid is closed. Can be prevented from floating. That is, in order to prevent the toilet seat or toilet lid from colliding with the toilet and generating a collision sound or being damaged during the closing operation, the toilet seat is close to the closed position (closed position), whether it is its own weight or electric. Or the speed of the closing operation of the toilet lid is extremely small.

  For this reason, the toilet seat or the toilet lid may stop the closing operation due to a small deformation of the toilet seat or the toilet lid, foreign matter, etc. Become. Applying a short time external force to the toilet seat or toilet lid in the closing direction with a motor after certifying the completion of closing eliminates the effects of small deformations and foreign objects, and rotates the toilet seat or toilet lid to the closed position from the floating state. It is something that can be done. The external force applied to the toilet seat or toilet lid by the motor in the closing operation direction does not need to consider the speed of the closing operation, and the magnitude of the external force can be appropriately selected.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a toilet device of the present invention, and FIG. 2 is a functional diagram of the toilet device shown in FIG. In FIG. 1, 1 is a toilet device, 2 is a toilet body, 3 is a toilet seat, and 4 is a toilet lid. A toilet seat 3 and a toilet lid 4 are attached to the upper part of the toilet body 2 so as to be rotatable up and down. The angle sensor 5 detects the rotation angle of the toilet seat 3 and the toilet lid 4, and the motor 6 closes (rotates downward) the toilet seat 3 and the toilet lid 4 and is controlled by the control unit 7. It is.

  The function of the toilet device 1 will be described with reference to FIG. 2. When the toilet seat 3 or the toilet lid 4 is manually closed and the angle A is reached, the angle sensor 5 detects and the control unit 7 drives the motor 6 to drive the toilet seat 3 or When the toilet lid 4 reaches a predetermined angle B (closed position), the angle sensor 5 detects and the motor 7 is stopped by the control unit 7. After a certain time has elapsed after reaching the closed position, the controller 7 drives the motor 6 and applies an external force in the closing direction to the toilet seat 3 and the toilet lid 4 for a short time.

  The fixed time after the elapse of the fixed time after reaching the closed position described here means not a predetermined time but after the motor 6 stops. Further, when external force in the closing direction is applied to the toilet seat 3 and the toilet lid 4 for a short time, the short time is not limited to a predetermined time but may be a time to reduce the float generated with the toilet body 2. Is the time in seconds. When the toilet seat 3 or the toilet lid 4 reaches a predetermined angle B (closed position), the toilet seat 3 or the toilet lid 4 has a very small closing speed, so that the toilet seat 3 or the toilet lid 4 is affected by small deformations and foreign objects and cannot reach the original closed position. The position sensor may stop without stopping, and a position shift due to a malfunction of the angle sensor 5 may occur, and these can be corrected.

The block diagram of the toilet device concerning this invention. The functional diagram of the toilet device of the Example shown in FIG.
