Description

Water saving toilet flusher of toilet bowl reservoir

The present invention relates to a drainage control device of the toilet bowl, and more particularly, a drainage control device of the toilet bowl reservoir that can control the amount of water drained when the water stored in the reservoir after draining into the toilet bowl.

Typically, approximately 30 to 40% of the water consumed at home is used in toilets.

The water used in the toilet is usually drained of water stored in the toilet bowl tank as it is, regardless of the type of excrement that the toilet user used after the toilet is inevitably consumed.

In particular, in the case of solid feces, a lot of water is consumed to remove it, in the case of liquid feces can be removed with only a small amount of water to remove it.

Most households, however, use all the water stored in toilet bowls to remove waste, regardless of solid and liquid waste.

Therefore, the amount of water used in the toilet bowl is always a lot, and accordingly, the increase of various costs and waste of water become severe.

Therefore, many efforts have been made to reduce the consumption of water used in toilets. The typical method is to increase the volume of water by inserting a brick or other object that can increase the volume of water in the toilet bowl to reduce the water consumption by the volume of the object in the tank.

However, this method is basically a temporary measure, not a method of reducing water consumption.

In addition, the method of increasing the volume of water results in a low amount of stored water. Therefore, sometimes the feces can not be completely removed in a single drain, the water must be stored in the reservoir again to drain the waste that has not been completely removed, and then the drained water must be drained again. have.

Therefore, scientifically, there is a need for a fundamental method of reducing water consumption for the removal of feces.

Therefore, the present invention has been devised to solve the problems of the prior art, and according to the purpose of using the toilet, by selectively draining the water stored in the reservoir to the toilet bowl to reduce the amount of water consumed in using the toilet bowl at home toilet It is an object of the present invention to provide a drainage control device for a toilet tank, which can fundamentally reduce the water consumption used.

Therefore, the drainage control device of the toilet bowl reservoir according to the present invention is a drainage control device of the toilet bowl reservoir to cut the drainage of the water stored in the toilet bowl tank and to supply the inside of the toilet bowl, the angular movement is installed on the overflow tube installed in the reservoir tank bottom An on / off valve for opening and closing the outlet of the outlet, a lift arm connected to the on / off valve with a wire to lift the on / off valve so as to angularly move the on / off valve to the first position or the second position, a clamp detachably attached to the overflow tube, It is connected to the wire between the on-off valve and the lift arm and is angularly mounted on the clamp so that the lever is lifted up and down to the first position or the second position in conjunction with the operation of the lift arm, and the angular motion is installed on the clamp so that buoyancy But the lift arm lifts the on / off valve to the first position. A buoyancy mechanism for limiting the angular movement of the latching lever to restrain the closing valve by self-weight and water pressure for a predetermined time until a predetermined amount of stored water is discharged; It includes a limit means for limiting the angular movement of the buoyancy mechanism to angular movement, when the lift arm and the locking lever moves the on-off valve to the first position, the buoyancy mechanism restricts the angular movement of the locking lever to the first position The on-off valve is prevented from closing rapidly due to its own weight and water pressure to drain some of the water stored through the outlet, and when the level of the reservoir is lowered so that the buoyancy of the buoyancy mechanism is lost, the on / off valve operates to block the outlet.

≪ First embodiment>

1 to 6 are views for explaining a first embodiment of the drainage control device of the toilet bowl of the present invention.

The drainage control device of the toilet bowl reservoir according to the first embodiment is in the closed position according to the angular movement of the valve frame on the valve frame 13 installed to enable the angular movement with the fixing pin 16 in the overflow tube 11 of the toilet bowl reservoir 10. There is an opening / closing valve 14 which opens and closes the outlet 12 of the bottom of the reservoir while moving to a half open or closed position (hereinafter referred to as a first position and a second position).

Here, the first position refers to a position in which the open / close valve 14 is half open, and the valve frame 13 is lifted to have an inclination of about 25 to 35 ° based on the fixing pin 16.

In addition, the second position refers to a position where the on-off valve 14 is completed, and the valve frame 13 is lifted to have an inclination of approximately 75 to 85 ° based on the fixing pin 16.

A chain wire 27 connected with a lift arm 28 which is lifted by a manual lever (not shown) installed on a toilet bowl outer wall for lifting the valve frame 13 to a first position and a second position is connected to a linkage ( 15) is installed.

Here, the manual lever is a conventional number for adjusting the opening and closing angle of the opening and closing valve by varying the lifting height of the lift arm 28 while moving in the 'large' or 'small' direction depending on the type of feces (feces, urine) Use the operating lever.

The clamp 17 is attached to the upper overflow tube 11 of the valve frame 13 so as to be detachable by the fixing bolt 18 so that the installation position of the overflow tube 11 can be changed.

Referring to FIGS. 2 and 3, the clamp 17 is secured by a fixing pin 28 and is connected to the chain wire 25 between the lift arm 28 and the connecting ring 15. It is formed there is a 'b' shaped locking lever 24 is lifted by angular movement within a certain distance around the fixing pin 28 according to the lifting of the lift arm 28.

In addition, one end of the clamp 17 is fixed to the fixing lever 22 to the lower side of the latch lever 24, and the other end is provided with a small hole 21 which can generate buoyancy at the other end is stored in the toilet bowl 10 When located in the water of the water, the holding tool support lever 20 angular movement around the fixing pin 22 by the buoyancy of the holding tool 21 is installed in a direction perpendicular to the locking lever 24.

Therefore, the angular movement directions of the support lever 20 and the locking lever 24 become directions perpendicular to each other.

Here, as long as it is possible to generate a constant buoyancy enough to angularly move the baking ball mouth frame 20, the baking ball hole 21 may be any type, but is preferably formed in a spherical shape.

In addition, the locking jaw 23 is formed on the upper surface of one end (upper pin 22) of the holding part support lever 20, and the locking jaw 23 is inclined surface 23- as shown in FIG. 1) and the contact surface 23-2.

Then, a stopper 19 is provided on a predetermined portion of the outer circumferential surface of the clamp 17.

The stopper 19 is preferably installed at the rear of the locking lever 25, which is the contact surface 23-2 of the locking jaw when the holding hole support lever 20 angularly moves by the buoyancy of the holding hole 21. The stopper 19 is in contact with each other to allow the sev ole support lever 20 to be angularly moved within a predetermined distance to prevent the sev ole support lever 20 from being completely tilted.

The control of the amount of drainage according to the type of excrement according to the first embodiment of the drainage control device of the toilet bowl of the present invention made in such a configuration is as follows.

1 is a state in which the water is stored in the reservoir in the drainage control device of the toilet bowl reservoir according to the present invention, the on-off valve 14 is a state in which the outlet 12 is closed by the water pressure of the valve and the water stored in the reservoir to be.

Referring to FIGS. 2 and 4, the locking lever 24 and the locking jaw contact surface 23-2 of the holding hole support lever 20 are in contact with each other, and the angular movement by the buoyancy of the holding hole 21 is caused. The angular movement of the holding tool retaining lever 20 is suppressed so that the opening / closing valve 14 is not affected by buoyancy.

In this state, half the opening / closing valve 14 will be described with reference to FIGS. 3, 4 and 5.

Here, the dotted line of FIG. 5 shows a state in which the on / off valve and the lift arm, the stop lever is half open and close the lift valve and the lift arm, and the latch lever position, and 'A' indicates the amount of discharged water.

In order to remove urine from the toilet bowl user and then remove the urine, the rotating arm 28 is lifted in a 'small' direction, and the lift arm 28 is lifted by a certain distance. ) Pulls the chain wire 27 to force the valve frame 13 in a closed state by self weight and hydraulic pressure to a first position having an inclination of about 30 to 40 °, and half the opening / closing valve 14 to open the outlet port. Allow the stored water to drain through (12).

At this time, in response to the movement of the first position of the opening / closing valve 14, the locking lever 24 is also lifted by a predetermined distance, and when the locking lever 24 is lifted, the holding part in a state where buoyancy is suppressed by the support lever 24 is lifted. The retaining lever 20 is buoyant is applied to the angular movement.

Then, when the swash mouth support lever 20 is angularly moved at a predetermined distance, as shown by the dotted line in FIG. 4, the engaging jaw contact surface 23-2 is in contact with the stopper 19, and the angular motion is restrained again. 20 is prevented from being completely flipped off.

In this state, the stored water is discharged through the outlet 12, and the opening and closing valve 14 is moved from the first position to the closed position by the self-weight and the hydraulic pressure of the stored water and the drainage pressure of the drained water, but the stopper 19 Angular motion is limited by the support lever 20 in which the engaging jaw contact surface 23-2 is in contact with each other.

This is because the locking lever 20 is caught on the locking jaw inclined surface 23-1 and no longer moved downward, so that the opening / closing valve 14 is not moved to the fully closed position, and is opened for a predetermined time when a predetermined quantity is discharged. State is maintained.

Thus, the stored water is drained continuously. Then, when the water is drained by a certain amount and the water level is lowered to the lower part 21, the buoyancy of the lower part 21 is released and the lower part supporting lever 20 is angularly moved downward by the weight of the lever. At the same time, the locking lever 20 is slid along the locking jaw inclined surface 23-1 of the support lever and moved completely downward to become the same state as the second degree.

Therefore, the opening / closing valve 14 is moved to the fully closed position by self-weight and water pressure to close the outlet 12, so that a portion of the water stored only while the opening / closing valve 14 is opened (indicated by 'A' in FIG. 5) Is drained.

In addition, referring to FIGS. 6 and 4 for explaining a state in which the on-off valve 14 is completed in the drainage control apparatus of the toilet bowl reservoir according to the present invention.

Here, the dotted line of FIG. 6 shows a state in which the on / off valve and the lift arm and the locking lever are moved to the completed on / off valve and lift arm and the latch lever, and 'B' is for indicating the amount of discharged water.

At this time, in the reservoir 10, the water is replenished to the original reservoir level by water replenishing means (not shown).

Referring to this, the completion of the opening and closing valve 14 in this state is to lift the toilet arm when the toilet operator to the toilet (not shown) to remove it, and then to remove it, the lift lever ( 28, the chain wire 27 is pulled more than when urine is removed, and the locking lever 24 and the valve frame 13 are erected with an inclination of about 70 to 80 ° to move to the second position to open / close the valve 14. Is completed.

This is the same as the opening and closing principle of the on-off valve in the existing toilet bowl.

The completed open / close valve 14 keeps the outlet 12 more open so that the stored water is discharged entirely through the outlet.

At this time, although the angular movement is supported by the buoyancy of the locator opening 21, the angular movement is limited by the stopper 19, so that buoyancy is suppressed.

Since the completed on / off valve 14 is almost vertically erected, the self-weight of the valve and the water pressure of the water hardly act, and the stored water is large because the drainage pressure from which the stored water flows out through the fully opened outlet 12 is large. Drains rapidly. This is the same principle that the water is drained through the outlet in the conventional toilet reservoir.

As the remaining water stored in the reservoir is discharged through the outlet, the water level is gradually lowered, the drain pressure received by the on-off valve 14 gradually decreases, and the on-off valve 14 is completely exposed on the water surface. The water pressure received by the water is completely disappeared and the outlet 12 is completely closed by the self-weight of the on-off valve.

Thus, the stored water is completely discharged through the outlet 12, and the discharged water removes the solid waste of the toilet.

≪ Second Embodiment>

7 to 10 are views for explaining another embodiment of the drainage control device of the toilet bowl of the present invention in detail.

Referring to this, the drainage control device of the toilet bowl reservoir according to the second embodiment is the valve frame 53 to the valve frame 53 installed to be fixed to the angular movement by the fixing pin 56 to the overflow tube 51 of the toilet bowl reservoir 50 According to the angular movement of the opening or closing position (hereinafter referred to as the first position and the second position below) there is an opening and closing valve 54 for opening and closing the outlet 52 of the bottom of the reservoir.

Here, the first position refers to a position in which the open / close valve 54 is half open, and the valve frame 53 is lifted to have an inclination of about 25 to 35 ° based on the fixing pin 56.

In addition, the second position refers to a position where the on-off valve 54 is completed, and the valve frame 53 is lifted to have an inclination of about 75 to 85 ° based on the fixing pin 56.

Wire connected to the lift arm 69 lifted by a manual lever (not shown) mounted on the outer wall of the toilet bowl 50 to apply lifting force for moving the valve frame 53 to the first and second positions. Connect the 68 to the connecting ring (55).

Here, the manual lever uses the same conventional manual lever as the manual lever used in the first embodiment.

A clamp 57 having a stopper 59 provided at a predetermined portion on an outer circumferential surface of the upper overflow tube 51 of the valve frame is detachably installed by the fixing bolt 58 so that the installation position can be adjusted.

The clamp 57 has one end fixed to both sides with a fixing pin 65, and the other end has a connection hole 66 to which a chain wire 68 between the lift arm 69 and the connecting ring 55 is connected. In accordance with the lifting of the lift arm (69) by the angular movement relative to the fixing pin (65) is lifted a certain distance, the end having a first contact surface (67-1) and a second contact surface (67-2) There is a locking lever 64 in which the jaw 67 is formed.

In addition, both ends are fixed to the clamp 57 and the fixing pin 62 at one end to the lower side of the locking lever 64, the other end is formed with a small flotation roller 61, the other end of the first locking to be opposed to the upper and left sides. The small floating roller frame 60 which is the jaw 63a and the second locking jaw 63b is formed.

The small float roller 61 of the small float roller frame 60 may be formed in any form as long as it can generate buoyancy. However, the small float roller 61 is capable of angular movement of the small float roller frame 60 by buoyancy. It is desirable to have buoyancy.

In addition, the positions of the first and second locking jaws 63a and 63b are formed at positions that are in contact with the stopper 59 during the angular movement of the small float roller frame 60, but the stopper 59 and the first locking jaw are positioned. When the 63a is in contact, the upward angular movement of the holding roller frame 60 is limited, and when the stopper 59 and the second locking jaw 63b are in contact, the downward angular movement is restricted.

The drainage control by the drainage control device of the toilet bowl of the present invention having such a configuration is as follows.

Referring to FIG. 7, this state shows the state of a normal toilet bowl tank, and the opening / closing valve 54 is closed by its own weight and water pressure, and the small float roller frame 60 is floating in the water by buoyancy. The second contact surface 63a-2 of the first locking jaw and the first contact surface 67-1 of the locking jaw 64 of the locking lever 64 are in contact with each other to suppress buoyancy.

9 is a view for explaining the half of the on-off valve. When the lift arm 69 is lifted by an actuating lever not shown, the lift arm 69 lifts the wire 68 and engages with the valve frame 53. Lift the lever 64 to the first position (indicated by the dotted line in FIG. 9).

The valve frame 53 lifted to the first position releases the stored water by half opening / closing the valve 54, and the latch lever 64 is lifted so that the small float roller frame 60 is angularly moved by a certain distance. The locking jaw first contact surface 63a-1 is in contact with the locking jaw second contact surface 67-2 of the locking lever 64, and the stopper 59 has a second contact surface 63a-2 of the first locking jaw. ) Is contacted so that the angular movement of the small float roller frame 60 is again limited.

Then, the half open / close valve 54 is moved to the closed position by the water pressure, the self-weight, and the drainage pressure of the stored water, but the second contact surface 67-2 of the locking jaw of the locking lever 64 and the small float roller frame ( The first contact surface 63a-1 of the first locking jaw of 60) is in contact with each other and is not completely closed.

Therefore, the stored water is continuously drained to the discharge port 52, and a certain amount of water is drained ('C' in Fig. 9) when the water level is lowered to the position below the small float roller 61, the buoyancy is released to the small float roller The frame 60 is angularly moved downward by its own weight so that the first locking jaw 63a is the inflection point of the first contact surface 67-1 and the second contact surface 67-2 of the locking jaw of the locking lever 64. When passing through, the supporting force for supporting the self-weight and the hydraulic pressure of the opening / closing valve 54 is lost, and the second contact surface 67-2 of the locking jaw of the locking lever 64 contacts the stopper 59 to open and close the opening / closing valve 54. ) Is moved to the fully closed position by self weight and hydraulic pressure.

In addition, referring to FIG. 10, the opening and closing valve is completed in the drainage control device of the toilet bowl according to the present invention.

Here, the dashed line in FIG. 10 represents a state in which the on / off valve and the lift arm, the latch lever is completed, the state of the open / close valve and the lift arm, the latch lever are moved, and 'D' is for indicating the amount of discharged water.

At this time, in the reservoir 50, the water is replenished to the original reservoir level by the water replenishing means (not shown).

Referring to this, the completion of the opening and closing valve 54 in this state is to remove the liquid waste to the toilet (not shown) and then to remove it, the rotation arm (not shown) to rotate the lift arm 69 is a wire ( 68 is pulled out and the locking lever 64 and the valve frame 53 are set to have an inclination of about 70 to 80 degrees and moved to the second position to complete the opening and closing valve 54. This is the same as the opening and closing principle of the on-off valve in a conventional toilet reservoir.

The completed opening / closing valve 54 opens the outlet 52 more openly so that the stored water is completely discharged through the outlet.

At this time, the small float roller frame 60 is angular movement by the buoyancy of the small float roller 61, but the angular movement is limited by the stopper 59 in the same way as the half of the opening and closing valve 54, the buoyancy is suppressed.

And, since the completed on-off valve 54 is almost vertically erected, the self-weight of the valve and the water pressure of the water hardly act, and the stored water is large because the drainage pressure from which the stored water is discharged through the completely open outlet 52 is large. Drains rapidly. This is the same principle that the water is drained through the outlet 52 in the conventional toilet reservoir.

As the remaining water stored in the reservoir 50 is discharged through the outlet 52, the water level is gradually lowered, the drain pressure received by the on-off valve 54 is gradually weakened, the on-off valve 54 above the water surface ) Is completely exposed, the water pressure received by the on-off valve completely disappears and the outlet 52 is completely closed by the self-weight of the on-off valve.

Thus, the stored water is completely discharged through the outlet 52, and the discharged water removes the solid waste of the toilet.

As described above above, the drainage control device of the toilet bowl reservoir of the present invention has a simple structure and is installed because the clamp is installed on the overflow tube of the existing toilet bowl tank, and connecting the locking lever to the chain wire And easy to dismantle, there is an excellent effect that can be used as it is without modifying the structure of the existing toilet bowl.

In addition, the drainage control device of the toilet bowl reservoir of the present invention can remove the urine contained in the toilet bowl by using only a portion of the water stored in the reservoir tank when urinary excretion of the toilet frequently used, so that the water consumption is basically It is possible to reduce, and to change the installation position of the clamp in the overflow tube can be adjusted to adjust the amount of water used to remove urine can be expected even greater water saving effect.
