JPS59390Y2 - Water saving structure in flush tank - Google Patents

Description

[Detailed Description of the Invention] This invention relates to the disclosure of an extremely practical water-saving structure based on water-saving in flush tanks, particularly early closure of the valve body in low tanks.

Therefore, conventional water saving methods of this type have been researched in many ways, such as improving the operating part to reduce the opening time of the valve, or changing the pipe diameter or water injection angle accordingly. However, they tend to be structurally complex, making them difficult to manufacture, install, and repair, and are often the cause of failures.

In addition, the water-saving structure in the previous precedent is difficult to modify after the fact, and it is difficult to set the amount of water injection that adapts to changes in drainage capacity that are required due to changes in various circumstances. This also makes it relatively difficult to set up the tank, especially to adjust it in response to changes in drainage pressure due to tank position.

Furthermore, in the prior art, a large amount of installation labor was required to install it on an existing tank, and in some cases, it was necessary to replace existing parts.

The present invention eliminates the inconveniences of the conventional model, makes it possible to reliably spray water according to the desired amount of water, and also makes it possible to make these modifications, eliminating the need for any installation work.
It can be easily installed on existing equipment, and the gist of the invention is a ball valve with floating properties that can be closed by suction with flowing water pressure against a valve seat provided on the opening of the water injection pipe. A flushing tank is installed so as to be openable with a cable of a predetermined size, and a pipe for hot water discharge and depressurization that protrudes slightly above the filling level of tank water is connected to the water injection pipe. In the configuration, a cylindrical liquid container is positioned above the valve seat and has a predetermined rising dimension and is fitted onto the pipe so as to be movable up and down, and a side peripheral portion of the container or
A loose fitting guide portion for the cable is provided at the bottom, and the body valve is placed at a point where the bottom surface of the container that moves downward in accordance with the downward movement of the filling water level can be brought into contact with and guided on the valve seat; Considerable design changes were planned in line with the gist of the configuration.

Hereinafter, details of the present invention will be described with reference to a typical embodiment shown in the drawings. Reference numeral 1 denotes a low tank connected to a flush toilet bowl, and this low tank 1 is automatically controlled to supply water by a ball tap 2. Washing water is replenished into the tank 1 at any time from a washing nozzle 4 via a water supply valve 3, and 5 is a valve seat provided on a water injection pipe 6,
A floating body valve 11 such as a rubber ball is provided via a cable connected to a valve opening lever for the valve seat 5.
The tank water 7 is ejected into the toilet bowl by the engagement action with the toilet bowl, thereby achieving the desired flushing.

Next, a pipe 8 is connected and erected on the side of the water injection pipe 6, and the upper end of the pipe 8 is slightly protruded from the upper limit line of the filled tank water 7 in the tank 1, so that the water 7 exceeds the line. When the water is replenished, this surplus water is discharged warmly, and the pipe 8 is used to supply air into the water injection pipe 6 after the valve is closed to drain the remaining water quickly and at the desired time. This ensures that the water is discharged into the toilet bowl with a flow pressure of 1000 ml, and that the body valve 11 is securely and smoothly fixed to the valve seat 5.

In contrast to the general low tank structure consisting of a cylindrical structure, a bottomed container 9 having a substantially cylindrical shape is separately prepared, and the container 9
The pipe 9a standing up from the bottom surface is bottomless, and a gap filled with liquid, particularly water, is formed between the pipe 9a and the peripheral rising wall 9b.

Note that this container 9 is not necessarily specified by the illustrated example, and if it is a normal liquid container, it is not necessarily specified by its shape, and even if it is a closed container, it may be a container without a pipe 9a. However, it is intended for use especially if it has the following operating functions:

Further, the container 9 is designed to have a predetermined rising dimension depending on the amount of water saved.

A container 9 having the above structure is fitted onto the pipe 8 so as to be movable up and down, water is replenished into the container 9, and the upper edge of the container 9 is slightly raised above the surface of the water 7 in the tank 1. It has been established,
For the purpose of performing this function, the container 9 is selected to have a specific gravity slightly lighter than that of the water 7.

Note that the cable 10 for operating the body valve 11 is tightly attached to a lever on the outside of the low tank 1, but the cable 10 is attached to a loose lever provided on the circumferential side or bottom of the container 9. It is extremely important in practice to ensure a loose fit between the body valve 11 and the container 9 by using the fitting guide part. pipe 9a
It was necessary to separately construct a guide pipe similar to the above.

The present invention is characterized by the above-mentioned configuration, and when the body valve 11 is springed by operating the lever, while the body valve 11 is floating in the tank water 7, the tank water 7 flows through the water injection pipe 6. As water 7 is discharged into the toilet bowl and the level gradually decreases, body valve 11 is pushed downward by the bottom of container 9 facing water injection pipe 6, and is further attracted to valve seat 5 with fluid pressure, ultimately closing the valve. The pipe 8 is suction-pressed onto the seat, and the negative pressure caused by the flow of water 7 inside the pipe 6 is eliminated, and air is sequentially supplied into the pipe 6.

Therefore, in the present invention, while the body valve 11 does not reach the direction of the valve seat 5, the body valve 11 is pushed down by the bottom surface of the container 9 to a position where the level of the water 7 is relatively high. At this time, the body valve 11 is guided onto the valve seat 5 and closed by suction.

The cables have dimensions such that the body valve 11 is pushed down to such an extent that the body valve 11 is positioned near the valve seat 5 with the bottom surface of the container 9, and the body valve 11 is attracted to the valve seat 5 and is placed inside the tank 1. When water is supplied again, the cable is provided with enough length to prevent tension from being generated due to the rise of the container 9.

The present invention is such that the body valve 11 is pressed and moved before the general operation of the body valve 11,
The fact that the pressure and movement of the body valve 11 was made possible using nine thin-walled containers whose specific gravity was lighter than that of water was particularly significant.

In other words, the manufacturing cost of the container 9 is extremely low, and the installation cost for the tank 1 is almost nil. could also be easily set.

In addition, when setting the amount of water to be sprayed, use the control valve 11 of the container 9.
This can be freely changed by changing the position of contact with the container 9, and in particular, by changing the length of the cylinder of the container 9, the desired amount of water can be determined.

In addition, it is also possible to adjust the amount of water sprayed at a subsequent request, and it is relatively easy to adjust the amount of water sprayed immediately depending on the usage situation of the toilet, not only at the time of installation but also after installation. It could have been set.

The present invention solves the inconveniences of the conventional model at once through the characteristic configuration described above, and discloses an extremely innovative water-saving structure that allows the radiation capacity of washing water to be easily set. It is related.
