Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in the floating structure of a flush cistern used in a flush toilet.

(Prior technology) Cistern uses a ball tap with a floating ball to keep the water level in the water tank constant, but when you turn the defecation lever, the water in the tank drains all at once. There was a problem in that more water was used than necessary when the user turned the lever for urinating or when a child was using the toilet.

(Problems to be Solved by the Invention) The present invention has been made in view of the above points, and its purpose is to stop the water supply from the cistern by stopping the water supply at a point lower than the set water stop level of the ball tap. To provide a floating structure of a cistern for flushing, which can reduce the amount of water discharged into a toilet bowl and can be easily adjusted even by an amateur.

(Means for Solving the Problems) The gist of the present invention is to provide a cistern for flushing, in which a water level adjustment float 3 having buoyancy is removably attached to the lower part of a floating ball 2 for metered water supply attached to a ball tap 1. This relates to a floating structure.

(Example) Hereinafter, the present invention will be described in detail based on the illustrated example.

Cisturn 4 is floating ball 2 as shown in Figure 3.
It is constructed by attaching a ball tap 1 with a mark to a water storage tank 5. The function of the cistern 4 is that after using the toilet, turning a lever (not shown) attached to the water storage tank and draining water from the drain port 6 of the water storage tank 5 lowers the floating ball 2, which in turn releases water from the ball tap 1. Water is supplied into the tank 5. As the water level in the water storage tank 5 rises, the floating ball 2 rises, and when the set water stop level is reached, water supply to the water storage tank 5 is stopped. 11 is a water pipe connection port, and 12 is a lid of the water storage tank 5.

Reference numeral 3 denotes a water level adjustment float, which is detachably attached to the lower part of the floating ball 2 and adjusts the still water level in the water storage tank 5.

FIG. 1 shows a first embodiment, in which the water level adjusting float 3 is formed by blow molding synthetic resin and has the shape of an animal. The front legs 7, the hind legs 8, and the nose 9 are used as locking parts 10. The manufacturing method and shape of the water level adjustment float 3 are not particularly limited as long as it can provide buoyancy.

Figure 4 shows the state in which the locking part 10 is locked to the floating ball 2 and the water level adjustment float 3 is attached, and the broken line A in the figure shows the water stop level when the water level adjustment float 3 is not attached. The solid line B shows the water stop level when the water level adjustment float 3 is installed. The difference between the still water levels A and B is, for example, about 80 mm. By attaching the water level adjustment float 3 in this way, the floating ball 2 can be positioned higher than the water surface by only the part of the water level adjustment float 3 that protrudes from the water surface, so that the water level at the time of water supply is set at the ball tap 1. Even when the water level is below the water cutoff level, water supply to the water storage tank 5 is stopped to reduce the amount of water stored in the water storage tank 5, and as a result, the amount of water drained into a toilet bowl (not shown) at one time can be reduced.

The front legs 7 and the hind legs 8, which are the locking parts 10, hold the floating ball 2 and are locked to the water level adjustment float 3. The front legs 7 and the hind legs 8 are made of an elastic material and are elastically deformed outward when the locked state is released. As shown in FIG. 2, the nose 9 is designed to removably fit the engaging body 9b into a recess 9a, and after inserting the support rod 14 of the floating ball 2 into the recess 9a, the engaging body 9b is fitted. The water level adjustment float 3 is locked in place. Note that the locking portion 10 is not particularly limited to the above structure as long as it can be locked in a detachable manner.

FIG. 5 shows a second embodiment of the present invention, in which the lower part of the floating ball is fitted into the fitting recess 13 on the upper surface of the water level adjusting float 3 and locked by the locking part 10.

(Effects) The present invention has a buoyant auxiliary float for adjusting the water level that is detachably attached to the lower part of the floating ball for metered water supply that is attached to the ball tap as described above. Only part of the floating ball can be positioned higher than the water surface, so even when the water level during water supply is below the set water stop level, water supply to the water storage tank can be stopped and the amount of water stored in the water storage tank can be reduced. As a result, the amount of water drained into the toilet bowl at one time can be reduced, resulting in a significant water saving effect.

Another advantage is that there is no need to adjust the ball tap itself, and the water level can be adjusted by an amateur.
