Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a water storage mechanism of a flush toilet having a function of eliminating the sounds of urination and defecation by the sound of water supply into a water tank.

[0002]

2. Description of the Related Art In the use of flush toilets, in order to eliminate the sounds of urination and defecation, the stored water in a water storage tank is often discharged before or during urination or during defecation. It is operated to let it flow out into the flush toilet bowl. When a flush toilet is used in this way, after the urination and defecation are completed, the stored water in the water storage tank is again discharged into the flush toilet as flush water. This causes waste of wash water.

Therefore, when the flush toilet is not used, the water storage tank is kept almost empty, and water supply is started in response to the operation of the flush lever. The sound of water supply eliminates the sounds of urination and defecation. A technique has been proposed in which flush water is caused to flow out into the flush toilet bowl by operating the flush lever again after the completion of urination and defecation.

One of them is a flush toilet water tank disclosed in Japanese Utility Model Laid-Open No. 56-138980. In such a water tank, a serrated engagement means is provided on a support rod of a float which constitutes a ball tap mechanism. In addition to the above, an engaging claw that engages with the engaging means of the water washing lever is provided, and the float can be maintained upward by the engagement of the engaging means and the engaging claw, and The float is moved downward by its own weight by releasing the engagement by rotating the lever in one direction.

Therefore, according to such a water tank, in the engaged state of the engaging claw of the flush lever and the engaging means of the float, the float is maintained above even if the inside of the tank is substantially empty. The valve of the ball tap mechanism can be closed, and in this state, prior to urination and defecation, the flush lever is rotated toward one direction to release the engaged state and move the float downward, The valve of the ball tap mechanism can be opened to start water supply into the tank, and the sound of water supply can eliminate the sounds of urination and defecation. Further, by moving the float upward by such water supply, the engaging claw of the flush lever and the engaging means of the float can be engaged again.
After that, the drain valve connected to the flush lever is opened by rotating the flush lever in the other direction in which the engagement is not released, and the water stored in the tank is used as flush water. Can be drained into the toilet bowl. Then, even if this wash water is discharged, the engaging claw of the wash lever and the engaging means of the float are engaged,
The float is maintained above and the tank is kept substantially empty until the flush lever is operated again. That is, according to such a water tank, water is started to be supplied to the tank by the first rotation operation of the flush lever prior to urination and defecation, and the flush water does not flow out by the first operation, and It is used so that the sound at the time of urination and defecation is erased by the sound of water supply, and the flush water is discharged by a second rotation operation of the flush lever in the opposite direction to the first rotation operation of the flush lever after urination and defecation. Can urinate,
It was possible to use the cleaning water without wasting it while eliminating the sound of defecation.

[0006]

However, in the conventional water tank, the stop of water supply to the tank accompanying the first operation of the flush lever is moved to the lower position by the first operation. Is moved upward as the water level rises due to the water supply, and the engaging means of the float and the engaging claw of the flush lever are engaged again. As a result, in such a water tank, urine is discharged before the float is moved upward,
When defecation is completed and the second operation of the flush lever is performed to allow flush water to flow out, the flush lever is temporarily stored without engaging with the engaging means of the float and the engaging claw of the flush lever. Water will flow out as wash water,
Even after urination and defecation were completed, the water supply to the tank was continued until the float was moved upward, and there was an inconvenience that the tank could not be prepared for the next use in a substantially empty state. . That is, in this case, if the first operation of the flush lever is performed when a flush toilet is newly used after this, flush water will flow out before urination and defecation are completed, and the flush water is wasted. Will be caused.

Further, in such a conventional water tank,
In order to operate properly, there is an inconvenience that the flush lever has to be operated so that the direction of rotation is different between the first operation and the second operation.

As a technique similar to that of the water tank, there is a muffler for stools described in Japanese Utility Model Laid-Open No. 57-56872. In this muffler, an iron plate provided on a float constituting a ball tap mechanism and an operation are also provided. The float is kept above by the attraction with the magnet linked to the button,
Since it is configured to maintain the closed state of the valve that constitutes the ball tap mechanism, like the water tank, urination and defecation are completed before the float is moved upward, and the operation button When the operation is performed, the water once stored in the state where the iron plate of the float and the magnet are not adsorbed flows out as washing water, and therefore, even after the urination and defecation are completed, the float is moved upward until it is moved. As the water supply to the tank was continued, it was impossible to prepare for the next use with the tank being almost emptied.

Therefore, the present invention is intended to eliminate the disadvantages of the prior art.

Further, in a water storage mechanism having a mechanism for muting the sound of this kind of urination and defecation by the water supply sound to the water tank, the water supply is started by rotating the water wash lever in one direction, and the ball tap is performed. Regardless of whether or not the water level rises to the position where the water supply is stopped by the mechanism, by rotating the water washing lever again in the same direction as the direction of the rotating operation for starting the water supply, the wash water is caused to flow out. It is an object of the present invention to stop the water supply and prepare the water tank for the next use in a substantially empty state.
