ABSTRACT OF THE DISCLOSURE
This invention relates to apparatus for flushing a water toilet and more particularly to a flush tank toilet having a counterweight connected to the discharge valve of the water tank so that said counterweight auto-matically urges said water discharge valve to a closed position when a quantity of water less than the capacity of the tank has been discharged from the tank.
ABSTRACT OF THE DISCLOSURE
This invention relates to apparatus for flushing a water toilet and more particularly to a flush tank toilet having a counterweight connected to the discharge valve of the water tank so that said counterweight auto-matically urges said water discharge valve to a closed position when a quantity of water less than the capacity of the tank has been discharged from the tank.
Description
This invention relates to apparatus for flushing a water toilet.
Flush tank toilets found in the market are constructed in a way such that in only one flushing, all the water contained in the tank is released into the bowl which is a lot of waste in terms of waste in terms of water consumed.
It is an object of the present invention to provide apparatus for flushing a water toilet which overcomes or at least mitigates the above-mentioned disadvantages.
Accordingly, the present invention provides a water flush toilet comprising a water tank; a bowl body secured to the water tank and including a downwardly extending waste material chamber having a water inlet communicating with the water tank and a discharge port communicating with a siphoning tube for directing the waste material into a drain line;
and a flushing assembly disposed within the water tank and comprising a discharge valve for discharging water into the water inlet of the waste material chamber and manually operable means for opening the discharge valve to cause water to flow through the discharge valve, the valve-operating means having counterweighing means for causing the discharge h--_ ~'~
- pa - I
valve to close after a given quantity of water less than the capacity of the tank has been discharged from the tank. The siphoning tube has a bent upper portion which extends considerably above the discharge port and then downwardly along a generally vertical section to join a lower horizontal portion of the siphoning tube. The vertical section has a generally uniform internal cross-section and sides that are gently curved along the length thereof. The size of the siphoning tube is relatively small to produce a siphoning effect and the lower portion has relatively small bumps extending across the bottom thereof serving initially to restrict the flow of the waste and water into the drain line, thereby causing pressure to build up at the higher end of the siphoning tube when water is released into the bowl body. The valve operating means comprises a flapper having a lever arm pivotal mounted to the water tank, the counterweighing means being connected to a chain secured between the lever arm and the discharge valve which is pivotal mounted to a lower end portion of an overflow tube.

Preferably, the given quantity of water it approximately one US gallon (3.8 liters).
A flushing assembly is disposed within the water tank and comprises a flapper having a lever arm pivotal mounted to the water tank, a chain connected to the lever arm, and a counterweight secured between the chain and the water discharge valve pivotal mounted to the lower end portion of an overflow tube. The counterweight has a preadjusted weight enabling the counterweight to move downwardly with the flow of water to urge the water discharge valve to close when a given quantity of water less than the capacity of the tank has been discharged from the tank.
In a preferred embodiment, the bent upper portion of the siphoning tube has a size reduced by one fourth compared to that of the standard flush toilet to achieve a siphoning effect when one-half gallon of water is discharged into the waste chamber.
Further features and advantages will become apparent from the following description of the accompanying drawings wherein:
Figure 1 is a perspective view of a flush tank toilet embodying the present invention .'~

Figure 2 is a cross-sectional view of the flush tank toilet;
Figure 3 is a perspective view of the flapper assembly showing the water discharge valve in open position; and Figure 4 is a perspective view of the flapper assembly showing the water discharge valve in a closed position and actuated by a tubal counterweight.
Referring now to the drawings wherein like numerals refer to like parts throughout, a flush tank toilet 10 generally comprises a bowl body 11 preferably made of figerglass-reinforced ceramic, a water tank 12 and a flapper assembly 16. The bowl body 11 and the water tank 12 are molded and assembled by chemical welding to produce a unitized flush tank toilet. The bowl body 11 is characterized by a downwardly extending waste material chamber 17 having a water inlet hole 18 and a discharge port 19.
A water trough 13 and siphoning tube 15 are provided internally of the bowl body 11. A lower horizontal portion of the siphoning tube is provided with a series of relatively small bumps or humps 25 extending across the bottom thereof.
The siphoning tube 15 has a bent upper portion 23 which extends considerably above the discharge port and the level of a neck portion 21 of the waste chamber 17 and then downwardly along a generally vertical section to join the lower horizontal portion Jo :~32~
of the tube. The vertical section has a generally uniform internal cross-section and sides that are gently curved along the length thereof. The siphoning tube lo has its size reduced by one fourth S compared to that of the standard flush toilet to produce a siphoning effect when flushing water of only one-half gallon is poured into the waste chamber 17. The series of bumps 25 along the lower portion 24 of the siphoning tube 15 is adapted to initially lo restrict the flow of water flowing into the drain line thus causing pressure to build up at the higher level of the siphoning tube 15 when water is released into the bowl body if. The water and the waste go over the humps as they surge into the drain line (not shown) producing a suction effect of increased intensity in the siphon tube 15. As a consequence the water closet flushes out the waste with just one gallon of water.
I I
The flushing assembly 16 consists of a flapper 26 having a lever arm 27 pivotal mounted near the upper left corner of the water tank 12. A
chain 28 is connected to the lever arm 27, and a counterweight I is connected between the chain 28 and a water discharge valve 30. An 5 overflow tube 31 is vertically disposed inside the water tank 12. A
discharge valve 3û is pivotal mounted to a lower end portion aye of the overflow tube 31.
The counterweight 29 has its weight preadjusted to enable it to 10 move downwardly with the flow of water and urge the discharge valve 3û to close a discharge outlet aye of the water tank 12 when one gallon of water has been released from the tank. The counterweight may also be in the form of a rod aye whose weight is also predetermined, as shown in Figure 4.
The talc 12 is automatically filled with water by means of a water inlet pipe 33 which is provided at the top end thereof with a water inlet valve 34 connected by a rod 36 to a float 35 which rises with the water level thereby closing the water inlet valve when the predetermined water line has been reached.
OPERATION
.
The flush tank toilet is operated by pressing the flapper 26. Water is then discharged in a limited amount of one gallon to the water trough 13.
25 As the water fills the trough 13 it flows into the bowl 11 through the inlet hole 18 and the opening around the inner periphery of the bowl. From tile bowl 11, the water and waste are expelled through the discharge port 19 into the siphoning tube 15. The water and the waste go over humps 25 as they surge into the drain line producing a suction effect thus allowing immediate 30 flushing of the waste with just one gallon of water. In a two gallon tank, two flushings can be made thus making the device more economical to use.
Thus, a flush toilet embodying the invention utilizes a counterweight whose weight is proportionally preadjusted against the total volume of the 35 water inside the water tank to enable it to move downwardly with the flow of water and urge the water discharge valve to a closed position when one gallon of water has been released thus preventing more water leaving the tank. A precise reduction in the size of the waste-and-water-way compared to that of the standard water closet is achieved and a series of humps is provided in the lower portion of the siphoning tube to create high pressure and subsequently a suction effect therein, thus aiding in limiting the amount 5 of the required flush water to only one gallon.
Although particular embodiments of the Invention have been desk cried, it is recognized that modifications may readily occur to those skilled in the art and consequently it is intended that the following claims be 10 interpreted to cover such modifications and equivalents.
