DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet water supply structure that can be used both as a main flush toilet and a simple flush toilet.

[0002]

2. Description of the Related Art In recent years, flush toilets that can be used both as the main flush toilet and the simple flush toilet have been provided. This can be switched between the main flush and the simple flush by changing the member connected to the outlet at the bottom of the toilet bowl. That is, by connecting a drain trap to the outlet, it can be used for main washing, and by connecting a valve unit to the outlet, it can be used for simple washing. In addition, to wash the toilet bowl, water is supplied from the drain port of a water tank such as a low tank.When opening and closing the drain port with a flush valve, the opening time of the flush valve should be extended for main flushing. The toilet bowl is cleaned neatly with a large amount of flushing water, and for simple flushing, the opening time of the flushing valve is shortened so that a small amount of flushing water is used.

[0003]

By the way, in the above-mentioned water supply tank, washing water is stored by a ball tap valve device so as to reach a predetermined water level. A hand-washing bowl and a water discharge faucet are provided above the water supply tank. In the case where a water tap can be provided for hand washing, a part of water spouted from the ball tap valve device is sent to a spout faucet, and the rest is directly supplied to a water supply tank. However, in the case of simple flushing, the amount of flush water supplied to the toilet bowl is small, the amount of water supplied to the water supply tank is also small, and a part of the water supplied from the ball tap valve device to the water supply tank is discharged as described above. When used for hand washing, there is a problem that hand washing water is insufficient. Conversely, if all the water is supplied from the ball tap valve device to the spout for hand washing, there is a problem that it takes time to supply water into the water supply tank at the time of main washing. Also, in the case of the main flushing specification, water can be discharged directly from the ball tap valve device into the water supply tank. After washing, water for sealing the bottom of the toilet bowl could not be supplied, and water could not be reliably sealed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and has been made to enable a sufficient amount of hand washing water to be supplied even during simple washing, and to allow a water supply tank to be supplied in a short time during main washing. Another object of the present invention is to reliably supply water for sealing after the toilet is washed at the time of main washing.
