BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water tank water supply device, and more particularly to a water tank water supply device capable of automatically supplying water to a water tank used in a flush toilet and ejecting high-pressure water from around the edge of a toilet bowl.

[0002]

2. Description of the Related Art By the way, in a general flush toilet, water is first stored in a water tank,
After that, if necessary, the water in the stored water tank
The sewage is washed away by squirting from the rim of the toilet bowl or spouting from the bottom of the toilet bowl, and the structure is such that each time it is washed, the water in the water tank is used up and then stopped. Therefore, in order to effectively wash away the filth, the amount of water stored in the water tank becomes a problem. That is, if the water stored in the water tank is sufficient, the filth can be washed out relatively completely.

However, as energy saving has become one of the issues in recent years and it has become more and more important, how to completely wash away the waste in the toilet with a relatively small amount of water is an important problem to be studied by the industry. Has become. Therefore, it is possible to arrange the water tank at a position higher than the toilet bowl and use the gravity of falling water to forcefully wash out the dirt in the toilet bowl with a relatively small amount of water, but install the water tank at a high place. This itself has a drawback that it causes inconvenience in construction and causes a defect in appearance. Therefore, in order to reduce the amount of water used and to effectively flush the waste in the toilet completely, and not to install a water tank at a high place, the waste in the toilet is flushed with the water pressure of the water itself. Is required.

In this respect, if the water head potential of the water supply pipe in a high-rise building is utilized, the originally required amount of water stored in the water tank is reduced, and if the water pressure in the building water supply line itself causes the water to be ejected from around the rim of the toilet bowl, It is considered that the swirl can be easily formed with sufficient momentum to improve the cleaning effect, that is, a relatively small amount of water can be spouted more vigorously than around the rim of the toilet bowl to wash away the dirt. . On the other hand, some water is also injected into the toilet after flushing the waste, and a trap is formed at the inner bottom of the toilet to prevent odor leakage in the waste discharge pipe with a water seal. Since the water pressures on the floors are different from each other, the amount of water injected into the trap at the bottom of the toilet bowl becomes excessive or insufficient, resulting in waste of water and inconvenience in use.

In view of the above-mentioned problems in the flush toilet water tank, the present invention allows the high-pressure water of the building water supply pipe to be jetted directly from the jet outlet around the edge of the toilet bowl, so that the water tank is relatively low even if it is arranged at a low position. An object of the present invention is to provide a water tank water supply device capable of cleaning a toilet bowl with a small amount of water.

[0006]

In order to achieve the above object, the present invention provides a water inlet (10) communicating with a water supply pipe connected to a water supply source, a water tank water inlet (11), and a toilet rim. Housing (1) provided with a water supply port (12) connected to a jet water pipe (121) communicating with the jet port in a three-way arrangement
And; pivotally mounted in the housing (1) and capable of pivoting the flap to an appropriate range, the water flowing from the water inlet (10) is supplied to the water inlet (11) of the water tank or the water inlet around the edge of the toilet bowl. A damper (2) which is controlled so that it can be introduced into (12); and a damper (2) which is pivotally mounted coaxially with the damper (2), has a weight (30) attached to one end, and a ball chain (41) at the other end. ) Via a switch lever (3) connected to a sub float (4) that floats up and down according to the water level in the water tank
A water supply valve (5) for controlling water entry into the tank is installed on the water inlet side of the water inlet (10). There is provided a water tank water supply device in which a main floating ball (50) for opening and closing the water supply valve of the water supply valve (5) is connected to (5) via a rod (51).

Furthermore, the damper (2) is pivotally mounted in the housing (1) to cover the side cover (15), and a plurality of pins (8) to be inserted and attached along the peripheral edge of the side cover (15). It is more preferable if the rotation angle of the switching lever (3) can be controlled by appropriately moving the insertion position of (1).

[0008]

When the present invention constructed as described above is mounted in the toilet water tank, when the water tank is full, the sub float floats above the water surface, and the switching lever operates by the weight. The water supply port to the weight tank is shielded by rotating the damper in the housing. Then, when you push the drain handle of the water tank to release the water, the water stored in the water tank springs out from the bottom of the toilet bowl, and the main floating ball and sub floating ball descend as the water level in the water tank drops, causing the main floating ball to drop. The water supply valve opens from the descent of No. 1, and high-pressure water in the building water supply pipe flows in from the water inlet of the housing, and jets from the outlets distributed around the toilet rim through the water supply port around the rim of the toilet and the jet water pipe. Further, when the water level in the water tank drops, the ball chains connected to the sub-floating ball and the switching lever at both ends extend completely from the descent of the sub-floating ball, pulling down one end of the switching lever, and the damper rotates. Then, close the water supply port around the toilet rim. As a result, the water flowing in from the water inlet is
Flows into the water tank through the water tank water inlet and water conduit,
The main float and sub float float up to the initial position as the water gradually fills up, and the water supply valve closes to shut off high-pressure water from the building water supply pipe, while the switching lever rotates by the action of the weight. The water supply port of the water tank will be blocked.

Then, the damper is pivotally mounted in the housing to cover the side cover, and the insertion positions of the pins inserted into the plurality of insertion holes formed along the periphery of the side cover are appropriately moved. Therefore, if the rotation angle of the switching lever can be controlled, the gap formed by closing the water supply port around the toilet rim of the damper can be adjusted appropriately, and the inflow amount of stagnant water that seals the bottom of the toilet can be adjusted by hydraulic pressure. It can be adjusted according to the difference.
