Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-saving device applied to a low tank for flushing a flush toilet.

[0002]

2. Description of the Related Art In general, flush systems for flush toilets are roughly classified into a flush valve system, a low tank system, and a high tank system. Of these, the low tank method is for supplying water stored in a fixed amount in a tank to a toilet, and is often used mainly for general housing because the water supply pipe diameter and the water supply pressure to the tank can be small.

FIG. 3 shows the internal structure of a raw tank. A water supply pipe 2 for supplying washing water to the inside of the tank 1 is connected, and water is supplied from the water supply pipe 2 to the inside of the tank and the hand washing 3. An end of the water supply pipe 2 is connected to a ball tap 4 in the tank, and an opening / closing valve of the ball tap 4 is connected to a floating ball 5. When the tank reaches a predetermined water level when the water level is full, the ball tap 4 is stopped and the water supply is shut off.

[0004] At the bottom of the tank, there is a drainage opening 7 connected to a drainage pipe 6, and normally, since the float valve 8 is in a closed state, the drainage opening 7 is closed. The float valve 8
A handle extending laterally from the valve portion is rotatably attached to a shaft provided near the base of the overflow pipe 9. A chain 10 is connected as a valve pulling member near the top of a valve portion having an upper surface formed in a hemispherical shape. The other end of the chain 10 is connected to a metal lever 11 having a bent end, and the root of the lever 11 is held by a rotary handle 12 provided on the outer wall side of the tank.

[0005] In the low tank of the flush toilet constructed as described above, when the user rotates the handle 12 at the time of washing, the lever 11 rotates and the chain 10 connected to the tip of the lever is pulled upward. Along with this, the float valve 8 is lifted to a predetermined height in water by the chain 10 while rotating about the shaft, and is opened. As a result, the washing water stored in the tank is discharged from the drainage opening 7 through the drainage pipe 6 to the toilet at once.

At this time, the float valve 8 lifted into the water stored in the tank maintains its open state for a while due to its buoyancy. During this time, the washing water in the tank continues to be discharged to the drain pipe 6. However, when a predetermined amount of cleaning water is discharged from the tank and the water level of the cleaning water decreases, the float valve 8 is again closed and the drainage opening 7 is stopped.

[0007] On the other hand, when the floating ball 5 drops due to a decrease in the liquid level in the tank, the valve of the ball tap 4 opens to supply water from the water supply pipe 2 to the handwash 3 and the tank, and the water level rises again. When the floating ball 5 reaches a predetermined height, the ball tap 4
Valve closes and shuts off the water supply.

[0008] The amount of water consumed in one flush of a flush toilet using a low tank as described above is determined by the amount of water stored in the tank and the opening and closing timing of each valve. Thus, a sufficient amount of water is set in consideration of the flushing function of the toilet and the like.

[0009]

In recent years, the analysis of the flushing operation of flush toilets has been advanced, and the number of toilets having a shape that can generally provide a more effective flushing action has increased. Considering the improvement of the flushing function of the toilet, the means for reducing the amount of water consumed by the flush toilet is significant from the viewpoint of saving water resources and reducing living costs.

The amount of water in the low-tank type flush toilet can be adjusted to some extent by changing the level of water stored in the tank and the lifting stroke of the float valve. It depends most on the opening time of the float valve. Among them, the opening time of the float valve, that is, the time from opening to closing of the valve depends on its characteristics such as the shape and buoyancy of the float valve. Therefore, it is possible to reduce the amount of water in the low tank system by deforming the float valve or the like. However, in order to make such a change, parts in the tank must be replaced, and a complicated operation is required.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to save water in a flush-type toilet that can easily reduce the amount of water in the flush-type flush toilet without replacing or processing existing parts in the low tank. To provide appliances for use.

[0012]

SUMMARY OF THE INVENTION A water-saving device according to the present invention is a device which is attached to a float valve which opens and closes to discharge and stop washing water in a washing low tank of a flush toilet, and which has a buoyancy of the float valve. Shall have a reduced weight. The water-saving device has a through-hole for passing a float valve lifting member connected to the float valve, and is installed in a state where the float valve lifting member is passed through the through-hole and is brought into contact with the upper surface of the float valve. Is preferable because it can be installed stably. By reducing the buoyancy of the float valve (increase the weight of the valve), the closing timing can be made earlier than usual, and the amount of discharged water can be reduced.

Specifically, such a water-saving device includes a bolt-shaped base having a notch reaching the through-hole from an outer surface for introducing the float valve lifting member into the through-hole provided therein, and the base. And a nut-shaped weight member having a notch through which the float valve lifting member is passed. Further, in a state where the base and the weight member are screwed together and locked, it is preferable to cut both screws so that the cutout of the base and the cutout of the weight member do not communicate with each other. With this configuration, in a state where the cutouts of the base and the weight member are aligned, the float member is passed through the cutout, the float valve lifting member is passed through the through hole, and the screw is screwed until the weight member is locked to the base. However, the water-saving device does not come off the float valve lifting member.

If a plurality of weight members can be screwed together, the weight on the float valve can be adjusted by adjusting the number of weight members to be attached.
It is preferable to use titanium or ceramics as a material for such a weight member because a sterilizing effect can be obtained. Furthermore, if a ring of a sterilizing material with a notch for passing the float valve lifting member is sandwiched by the weight member, it will help purify the water in the tank and can be diverted as emergency drinking water in the event of a disaster Also becomes possible. As the sterilizing material, ceramics or mineral titanium can be used. In particular, it is preferable to use a ceramic ring because it has a function of absorbing rust. Alternatively, it is possible to use a magnet ring of a strong permanent magnet as a ring of the sterilizing material, in which case the water accumulated in the toilet tank can be made into magnetized water to activate small clusters of water. In addition, it is possible to prevent and remove the deposition of water scale on the inner surface of the tank and the inner surfaces of the various devices in the tank, the toilet, and the drain pipe. In addition, since sterilization can be promoted by creating magnetized water, safety as emergency water in the event of a disaster can be improved.

Further, in a water-saving device comprising a base and a weight member, the base and the weight member may be subjected to a chamfering process. In other words, tanks are generally made of earthenware,
If there is a corner when dropped during construction, cracks and the like are easy to enter. Therefore, rounding the corners by performing chamfering (including deburring) leads to protection of the tank.

[0016]

FIG. 1A is a perspective view showing one embodiment of a water-saving device according to the present invention, and FIG. 1B is an exploded view thereof.

The bolt-shaped base 110 has a through-hole 111 penetrating along the central axis thereof, and a notch 112 provided so that a chain as a float valve lifting member can be introduced into the through-hole 111. And The base 110 has a flange shape at the bottom, and is used so that a threaded threaded portion is located above. As will be described later, the bottom side of the base of the through hole 111 is located at the connecting portion between the chain and the float valve in the mounted state, so that the base portion of the base is floated so as not to interfere with the connecting portion. It is good to make stable contact with the valve. In the water-saving device 100 of the present example, the bottom side of the inner diameter of the through hole 111 is larger than the upper side,
The inner diameter of the through hole 111 on the bottom side is widened so that the connecting portion can be accommodated (not shown). Thereby, the base 11
The bottom surface, which is wider than the other with a zero flange shape, comes into planar contact with the upper surface of the hemispherically formed float valve.

The weight member 120 has a notch 11 in the base.
A notch 121 having the same width as 2 is provided. The water-saving device 10 is attached to the chain as the float valve lifting member.
When attaching 0, a predetermined number of weight members 120 are attached to the base 110 in advance, and the positions of the cutouts 121 are aligned with the cutouts 112 of the base.
In this state, the chain is introduced into the through hole 111 through the notch, and the weight member 120 is screwed into the lower flange side of the base 110 in order from the lower side and locked. At this time, the screw is cut so that the notch 121 of the weight member does not coincide with the position of the notch 112 of the base. Although four weight members 120 having the same shape are illustrated here, the number of weight members may be appropriately adjusted in actual use.
As the number of weight members 120 increases, the valve closes earlier. Further, if a ceramic ring or a titanium ring having the same shape, also formed with a notch, is sandwiched between such weight members 120, the effect of rust prevention and sterilization can be obtained by the action. The ring of sterilizing material does not have to be threaded. When a ceramic ring is used, it is preferable to use far-infrared reinforced ceramics. In particular, when mixed with lava powder or the like, the sterilization effect can be enhanced by utilizing the magnetism of lava. It is also possible to combine permanent magnet magnet rings.

FIG. 2 is a sectional view of the low tank 1 of the flush toilet in a state where the water-saving device 100 is attached. The water-saving device 100 is located at a portion where the float valve 8 is closed and connected to the chain 10 which is a float valve lifting member, and is in contact with a top portion at the center of the float valve.

When the handle 12 is rotated during washing, the lever 11 rotates and the chain 10 is pulled up. As a result, the float valve 8 is lifted to a predetermined height and opened when the water-saving device 100 is attached, and the washing water in the tank is discharged from the drainage opening 7. At this time, the float valve 8 is lifted to a predetermined height and maintains the open state for a while, but since the buoyancy is reduced by the weight of the water-saving device 100, the drainage opening 7 is stopped at a timing earlier than usual. I will be.

Since the water-saving device 100 of this embodiment can be installed with one touch as described above, it is an existing low tank installed in a place where it is difficult to obtain a sufficient working space, for example, a low tank used in a state where the wall is embedded. It can be easily mounted.

[0022]

According to the water-saving device of the present invention, the water tank can be installed without changing the existing structure of the low tank for washing the flush toilet, and the amount of water can be reduced. Further, since the number of weight members can be adjusted, fine adjustment of the amount of water can be easily performed. Furthermore, since attachment and detachment can be performed by one-touch operation, it can be attached with one hand regardless of a work space.
