Description

Water-saving toilet bowl

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-saving toilet bowl, and more particularly, to a water-saving toilet bowl in which a drainage amount of a toilet can be separated into faeces and urine and discharged.

In general, a water tank constituting a flush toilet of a flush toilet is provided with a handle provided to be exposed to the outside, a lever provided inside the water tank to be interlocked with the handle, a bead wire formed by connecting a plurality of beads, And a drain pipe selectively opened and closed by the valve.

When the user operates the handle, the valve rotates around the hinge and is lifted upward, and the drain pipe is opened. When the drain pipe is opened like this, the water in the water tank is discharged through the drain pipe and the dirt is removed together with the toilet water.

When the handle returns to its original position, the valve will descend with the water surface and eventually block the drain pipe.

However, the amount of water used to urinate a small amount of urine is the same as the amount of water sent down the stool, so that the amount of water used to urinate frequently is wasted.

In order to solve such a problem, Korean Utility Model No. 187573 has disclosed a water saving valve for a toilet.

The conventional water-saving valve is advantageous in that it can save water because it only discharges water necessary for removing dirt by the action of a bucket and quickly cuts off the water pipe. However, since the shape of the valve becomes complicated, productivity is lowered, There is a problem in that the unit price is increased because a bill is added.

[0004] Meanwhile, the conventional art for water saving of a toilet has been disclosed in Korean Patent No. 10-1030917 (entitled " a toilet bowl with a rotatable urinal attached thereto ") as a toilet bowl that allows a male urinal to be separately assembled and used in a conventional toilet bowl Lt; / RTI >

The toilet has a urine discharge tube of a U-shaped trap integrally formed on both sides of the rear body of the toilet, a rotatable and adjustable urinal connector, a male urinal including a lid and a water supply pipe and a water supply valve Body.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and it is an object of the present invention to provide a water-saving toilet bowl which can save water by being able to select a drainage amount of wash water to be suitable for faeces or urine, respectively.

In addition, since the level of water in the bowl of the toilet can be maintained at an appropriate level, accumulation of dirt can increase the water level, so that the discharge can be automatically performed. Thus, clogging can be prevented by the water pressure discharged at a time, In order to provide a toilet.

The above object of the present invention can be also achieved by a water drainage device comprising a water tank for storing wash water and opening and closing a drain hole formed in the water tank and a toilet seat having a space in which water is stored, In a toilet with a main body,

The water drainage device includes a first hinge part hinged to a bottom surface of a water tank to open and close a drain port of the water tank, a convex part inserted into the drain hole is formed, and a water inlet is formed in the convex part, A first valve cap for opening and closing the valve body; A tubular body having a lower end connected to an upper surface of the first valve plug, an opening formed at upper and lower ends thereof, and a passage formed therein; A first lever connected to the first valve stopper or the pipe body, a first lever connected to the first wire and formed outside the water tank and opening the first valve stopper by pulling the first wire; A second valve plug having a second hinge portion hinged to an upper end opening of the tubular body and opened and closed; A second lever connected to the second valve plug and a second lever formed on the outside of the water tank and connected to the second wire to pull the second wire to open the second valve plug, Can be achieved.

The first hinge portion and the second hinge portion are formed at opposite positions.

The first valve plug is formed in a hemispherical shape convex downward and is formed to have a diameter inserted into a drain hole.

The second valve cap is characterized in that the exhaust pipe is vertically penetrated and coupled to discharge the internal air of the tubular body.

[First Embodiment]

2 is an exploded perspective view showing a water drainage device W of a water-saving type toilet seat according to the present invention. Fig. 3 is an exploded perspective view of a water-cooled type toilet according to the present invention. Fig. FIG. 4 is a view showing a secondary operation of the water-saving type toilet bowl according to the present invention. FIG.

1 to 4, the water-saving type toilet bowl includes a water tank 500 in which washing water is stored, and a water drainage device W for opening and closing a drain hole 520 formed in the water tank 500 ).

And a bowl body 2 having a space for storing water and formed with a discharge port 22 at a lower portion thereof.

The water drainage device W includes a first valve plug 600, a tubular body 700, a first lever 800, a second valve plug 900, and a second lever 960.

The first valve plug 600 is formed at one side with a first hinge portion 610 hinged to the bottom surface of the water tank 500 to open and close the drain port 520 of the water tank 500, A convex portion 620 is formed in the convex portion 620 and a drain hole 630 is formed in the convex portion 620 to open and close the drain hole 520.

The first valve plug 600 is formed with a hemispherical convex portion 620 which protrudes convexly to the lower portion of the disk member having a diameter larger than the diameter of the drain hole 520, The protrusion 620 is formed to have a diameter to be inserted into the drain port 520. The protrusion 620 is formed so as to have a weight due to its own weight, 620 are formed with a thickness having a load.

The tubular body 700 is formed in a cylindrical shape and a passage 720 is formed therein. The lower end opening is fixed to the upper surface of the first valve plug 600, and the length thereof corresponds to the water level of the water tank 500 .

For example, water is stored so as to have a water level of about the length of the tubular body 700, and this volume of water is the amount of water that is consumed once to lower the feces.

Water stored above the upper opening of the body 700 corresponds to the amount of water consumed to urinate.

For example, the amount of water consumed to send down the stool is 2 liters, and the amount of water consumed to urinate is set to 1 liter.

The first lever 800 includes a first wire 810 connected to the first valve plug 600 or the tube 700 and a second wire 810 connected to the first wire 810 to be formed on the outside of the water tank 500 And pulls the first wire 810 to open the first valve plug 600.

Similarly, when the second hinge unit 910 is rotated, the first hinge unit 610 is not rotated so that the closed state can be maintained.

On the other hand, the second valve plug 900 is vertically penetrated through an exhaust pipe 980. The internal air of the tube 700 can be discharged through the exhaust pipe 980.

The second valve plug 900 may be completely closed when the air in the tube 700 is discharged so that the second valve plug 900 may be lifted and the airtight state may not be precisely performed. So that the exhaust pipe 980 is raised above the water level so that water does not flow back through the exhaust pipe 980.

Hereinafter, the operation of the present invention will be described.

3, when the urine needs to be sent down, the user presses the second lever 960 and the second wire 920 is interlocked to pull the second valve plug 900 to open, 700, and is transferred to the toilet bowl through the water inlet 630 of the first valve plug 600 to be discharged together with the urine.

4, when the user needs to push down the first lever 800, the first wire 810 is interlocked with the first lever 800 to lift the first valve plug 600 or the tube 700 So that the drain hole 520 is opened.

Accordingly, the massively stored water in the water tank 500 can be transferred to the toilet bowl through the drain port 520 and discharged together with the faeces.
