[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet flushing tank device, and more particularly to a toilet flushing tank device capable of switching the amount of water supplied to a toilet bowl to a large side or a small side by rotating an operation handle.

[0002]

2. Description of the Related Art Some conventional toilet flushing tank devices include, as disclosed, for example, in Japanese Patent Publication No. 60-27780, in which an operation handle provided on a tank body is turned to a large side or a small side. By selectively switching between large washing in which the flush water stored in the tank body is completely supplied to the toilet and small washing in which a predetermined amount of washing water is left in the tank body, thereby saving water. There are things. FIG. 15 shows a conventional toilet flushing tank device capable of selecting between large flushing and small flushing.

This toilet bowl washing tank device 100 has a drain port member 102 connected to a toilet bowl at the bottom inside a tank body 101.
And a lower end of a water storage tank 104 is connected to the drain port member 102, and a cylindrical body 103 is provided outside the water storage tank 104.
Is provided, and the water storage tube 104 is accommodated inside the cylindrical body 103. An overflow pipe 105 is vertically slidably fitted into the center of the water storage pipe 104, and a drain port member 1 is attached to a lower end of the overflow pipe 105.
02, which is seated on a drain valve seat 102 'provided in
6, and the drain valve body 106 and the drain valve seat 102 ′ constitute a drain valve 120. The drain valve 120 is opened and closed with the vertical movement of the overflow pipe 105. A float 107 is attached to a middle portion of the overflow pipe 105 via a support piece, and the float 107 is housed inside the water reservoir 104 so as to be able to ascend and descend. Two connecting chains 109 and 110 hang down from an operation handle 108 provided at an upper portion in the tank main body 101, and their lower ends are opened at the upper end of the overflow pipe 105 and the middle of the peripheral wall of the cylindrical body 103. Are connected to an on-off valve body 112 provided at an inflow port 111.

When the operation handle 108 is turned to the large side in the toilet bowl washing tank apparatus 100 configured as described above, the drain valve 106 at the lower end of the overflow pipe 105 is pulled up via the connecting chain 109, and the drain valve 120 is opened. Open the valve. As a result, the washing water in the tank body 101 passes through the opening 113 provided in the lower part of the peripheral wall of the water storage cylinder 104 and is supplied from the drain valve 120 to the toilet. In addition, at the time of large washing, the connecting chain 1
The lifting amount of the valve 10 is small, and the on-off valve body 112 provided at the inflow port 111 does not operate in the valve-open state. Therefore, the washing water in the tank main body flows from the inflow port 111 which is largely opened, and is further drained from the drain valve 120 as described above after passing through the opening 113 of the water storage cylinder 104. Therefore, at the time of the large washing, drainage is performed until the water level in the tank main body 101 falls to the lower end of the inflow port 111, and the washing water stored in the tank main body 101 is drained without being left.

On the other hand, a small through hole 11
4 is provided, and the water in the water tank 104 is gradually drained from the small through hole 114 in parallel with the water level in the tank body being lowered by the drainage performed as described above. After the drainage of the washing water is completed, the user sits on the drain valve seat 102 'and closes the valve. After the drain valve 120 is closed, water is supplied from a water tap (not shown) provided on the upper portion of the tank body 101, and is continued until a predetermined amount of washing water is accumulated in the tank body. When the operation handle 108 is rotated to the small side during the small washing, the drainage valve 1
The valve 20 is opened to start supplying water to the toilet, and the opening / closing valve body 112 of the inflow port 111 is closed by pulling up the connecting chain 110. Therefore, all drainage from the drain valve 120 is performed between the cylindrical body 103 and the water storage cylinder 104. Moreover, the water level in the tank body is cylindrical 1
When the cleaning water stops flowing to the upper end of the cylinder 03, the washing water stops flowing into the cylindrical body 103, and then the water level in the water storage cylinder 104 decreases due to the drainage from the small through hole 114, and the float 107 is lowered and the drain valve body 120 closes. At this time, the flush water is left in the range below the upper end of the cylindrical body 103 in the tank body, and as a result, the amount of the residual flush water supplied to the toilet is reduced.

[0006]

The above-mentioned conventional toilet flushing tank device has a water tank 10 containing a float 107.
4, a cylinder 103 is provided on the outside of the cylinder 103, and an on-off valve body 112 provided at an inflow port 111 of the cylinder 103 is opened and closed.
Since the lower limit of the water level in the tank body at the time of drainage is configured to be changed, it is necessary to provide the cylindrical body 103 outside the water storage cylinder 104 and arrange the containers in a double manner. The size of the surrounding structure is inevitably increased,
Since the number of parts increases, the manufacturing cost also increases.

[0007] An object of the present invention is to provide a toilet flushing tank device having a function of switching between large flushing and small flushing as described above, without having to dispose containers twice around the drain valve to increase or decrease the amount of water supply. An object of the present invention is to provide a means capable of switching, thereby realizing simplification of the structure and reduction of the number of parts.

[0008]

In the toilet flushing tank device of the present invention, a drainage port communicating with the toilet bowl is opened upward at the bottom of the tank body, and a drainage valve body can be opened and closed from above with respect to the valve port formed by the drainage port. To constitute a drain valve, and attach a float to the drain valve to float the valve,
The float body is housed in a control vessel installed at a predetermined height at a predetermined distance from the bottom of the tank body so as to be able to move up and down. The upper part of the control vessel is opened, and the float flows into the bottom wall of the vessel. An outlet and a small through-hole are respectively opened in the lower part of the container, and one of the two connecting members pulled up by the rotation of the operation handle provided in the upper part of the tank main body, one of the two connecting members is the drain valve body, and the other is the control container.

A pull-up mechanism for switching the amount is provided on the operation handle, and when the operation handle is turned to the small side, the opening / closing valve lid is slid in the valve opening direction by the pull-up mechanism, and the operation handle is turned to the large side. Time, opened by the lifting mechanism The valve cover is configured to maintain the closed state, and the urging means constantly applies a biasing force in the closing direction to the open / close valve cover and operates the open / close valve cover from the open position to the closed position for a predetermined time. An operation delay mechanism for delaying the operation is provided.

[0013]

According to the above means, the drain valve of the drain valve provided at the bottom of the tank body is seated on the drain port by the water pressure of the washing water stored in the tank body and maintains the valve closed state. In addition, the float attached to the drain valve body is housed in a control container installed in the lower part of the tank body so as to be able to move up and down, and obtains buoyancy from water filling the container. When the operation handle is turned to the large side during a large flush, the drain valve body of the drain valve is pulled up via one connecting member, and the washing water stored in the tank body is supplied from the drain port to the toilet. Is started. Once the drain valve is lifted from the drain port, the drain valve maintains an open state due to buoyancy of the float contained in the control container. In addition, at the time of large washing, the lifting amount of the other connecting member is reduced by the lifting mechanism, or the lifting direction is directed to the closing direction, so that the on-off valve lid provided at the outlet maintains the state where the outlet is closed. I do.

When the water level in the tank body drops as the washing water in the tank body is drained from the drain port and drops to the opening at the top of the control vessel, the washing water in the tank body is controlled from the opening. The washing water in the tank body does not flow into the container, and a large amount of washing water is drained from the drain port, and the water level drops rapidly. In parallel with this, the water in the control vessel also flows out of a small through hole provided in the lower part of the vessel, and the water level in the control vessel gradually decreases, and the float floats accordingly. However, since the amount of drainage through the small through hole is small, the float is lowered relatively slowly over time. Therefore, all the washing water in the tank body is drained before the float body descends and the drain valve is seated at the drain port, and the drain has already been completed.

Further, when the operation handle is turned to the small side during the small washing, the drain valve body is pulled up to start water supply to the toilet, and the other connecting member is largely pulled up by the lifting mechanism or the lifting direction. Is turned in the opening direction, whereby the on-off valve lid at the outlet is opened. When the washing water in the tank body decreases with the drainage and drops below the opening at the top of the control container, the outlet of the control container is sufficiently opened, so the water in the container also drains into the tank body due to drainage. As the water level decreases, the water flows out from the outlet. Therefore, the water level in the control vessel also drops rapidly as the water level in the tank body, and the outlet opening corresponding to the predetermined height of the control vessel side wall, that is, the minimum level of the water level in the tank body at the time of small washing. To the position of. Then, the floating body accommodated in the control container is lowered together with the water level in the control container, and at the time when the float reaches the above-mentioned level, the drain valve seats on the drain port and closes. At this time, flush water remains in the area below the control container outlet in the tank body, and the supply amount of flush water to the toilet is reduced accordingly.

In the toilet flushing tank device according to the second aspect, the outlet is opened and closed by moving the open / close valve lid for closing the outlet of the control container up and down along the side wall of the control container. Therefore, at the time of small washing, the opening / closing valve lid is largely pulled up via the connecting member by the rotation of the operation handle, and the outlet of the control container is opened. Conversely, at the time of large washing, the amount of pulling up by the connecting member becomes small, and the on-off valve lid is kept in the closed state. Further, the opening / closing valve lid lifted during the small washing is lowered by its own weight, but the lowering is delayed by a predetermined time by the lowering delay mechanism. Therefore, during the delay time, the on-off valve lid is opened, whereby the water in the control container flows out rapidly from the outlet, and the closing of the drain valve body is hastened.

According to the third aspect of the present invention, the open / close valve lid is supported rotatably like a door between a closed side and an open side around a pivot axis along one side of the valve lid. You. At the time of small washing, when the connecting member is pulled toward the open side by the rotation of the operation handle, the on-off valve lid moves to the open side and the outlet is opened. The water in the control vessel quickly flows out from the opened outlet, and the closing of the drain valve body is hastened. At the time of large washing, the connecting member is pulled in the closing direction, and the on-off valve moves to the closing side to close the outlet.

According to the fourth aspect of the present invention, the opening / closing valve lid is rotatably supported between the closed side and the open side along the side wall of the control vessel around the support shaft at one end. . Therefore, at the time of small washing, when the connecting member is pulled toward the open side by the rotation of the operation handle, the on-off valve lid is rotated to the open side and the outlet is opened. Water in the control vessel quickly flows out of the opened outlet as described above, and the closing of the drain valve body is hastened. At the time of large washing,
The connecting member is pulled toward the closing direction, and the on-off valve cover moves to the closing side to close the outlet.

[0019] In the toilet bowl washing tank device according to claim 5,
The opening / closing valve lid closes an outlet provided on the bottom wall of the container, and is supported to be openable and closable while sliding along the bottom wall of the container. Further, the opening / closing valve lid is constantly urged in the closing direction by the urging means, and is kept closed by this urging force. When the connecting member is largely pulled up by the rotation of the operation handle at the time of small washing, the opening / closing valve lid slides to the open side to open the outlet. The opened / closed valve lid moves back toward the closing side by the biasing force of the operation delay mechanism, but moves slowly over a predetermined time by the delay function of the operation delay mechanism. Therefore, the water in the control container quickly flows out of the outlet that keeps a large opening during the delay time as described above, and the closing of the drain valve body is hastened. In addition, at the time of large washing, the amount of lifting by the connecting member becomes small, and the on-off valve lid maintains the closed position and closes the outflow port.

[0020]

As described above, according to the present invention, by selecting the rotation direction of the operation handle between the large side and the small side,
The drainage from the drain valve is started with the outlet provided in the control container closed or opened by the on-off valve lid, and the timing of closing the drain valve is delayed by changing the water level drop time in the control container. It is configured to control the case (at the time of large washing) and the early case (at the time of small washing) to selectively switch the size of the amount of washing water drained from the tank body to the toilet. It is no longer necessary to dispose containers twice around the drain valve as in the toilet flushing tank device described above, and the function of switching the amount of drainage can be exhibited only by the control container. Therefore, at the same time as simplifying the structure,
The cost can be reduced by reducing the number of parts, and the area around the drain valve can be made compact so that the space in the tank body can be used effectively.

According to the second aspect of the present invention, in addition to the above effects, the structure of the on-off valve lid is simplified, and the time from opening to closing of the on-off valve lid is set by the descent delay mechanism. Thus, the amount of water supply at the time of small washing can be set freely. According to the third aspect of the present invention, the structure of the on-off valve cover can be simplified, and the opening and closing operations of the on-off valve cover can be reliably performed. In the toilet flushing tank device according to the fourth aspect, the structure of the on-off valve lid is simplified, and the opening and closing operations of the on-off valve lid can be reliably performed.
In the toilet flushing tank device of the fifth aspect, the structure of the on-off valve lid is simplified, and the time from opening to closing of the on-off valve lid is set by the operation delay mechanism so that the amount of water supply during small flushing can be freely set. Can be set.

[0022]

Embodiments of the present invention will be described below with reference to the drawings. A toilet flush tank device a shown in FIG. 1 is installed above a toilet (not shown), and a drain valve 3 for supplying flush water to the toilet is provided on a bottom portion inside a ceramic tank body 1. At the same time, an operation handle 4 for opening the drain valve 3 is provided at an upper portion of a peripheral wall of the tank body 1 and a ball tap water tap for supplying water supplied from a water supply source to a water supply level in the tank body every time the toilet is washed. 2 is provided. The upper end of the water supply pipe 12 that connects the tank body 1 and the toilet is fitted into the opening on the bottom surface of the tank main body 1, and the upper end of the water supply pipe 12 is configured as a drain port 32. The drain port 32 constitutes a valve port of the drain valve 3, and opens upward on the bottom surface in the tank body 1, and the drain valve body 31 is seated on the drain port 32 from above.

The disc-shaped drain valve body 31 is attached and fixed to the lower end of the overflow pipe 15, and a hole 31 a is formed at the center thereof to allow water flowing down the overflow pipe 15 to pass through the drain port 32. is there. Overflow pipe 1
5 penetrates a central portion of a control container 5 described later,
And is slidably supported up and down. The control container 5 is a substantially D-shaped container having an open top surface, and is mounted and supported on the bottom surface of the tank body 1 via the legs 14 so as to be installed at a position slightly above the bottom surface in the tank body 1. is there. Note that the control container 5 described above may have a shape other than the flat D shape. In addition, a middle tube portion 5a is provided in the center of the control container 5 in a vertically penetrated state, and the overflow tube 15 is slidably fitted along the inside of the middle tube portion 5a. At the rising end, a drain valve body 31 provided at the lower end of the pipe abuts against the bottom surface of the control vessel 5 to set the upper limit of floating by the float 7 described later.

From the outer periphery of the upper part of the overflow pipe 15, two connecting members 13 extending into the control vessel 5 are protruded so as to avoid the middle cylinder portion 5a, and hollow connecting members 13 are provided at the lower ends of the connecting members 13, respectively. 7 is attached and fixed. The float body 7 is a hollow body that generates buoyancy enough to float the overflow pipe 15 and the drain valve body 31. The float body 7 is housed inside the control vessel 5 and integrated with the overflow pipe 15 via the connecting member 13. It is supported so as to ascend and descend in the container 5 as it moves up and down.

An outlet 8 is opened in the flat portion 5b on the side wall of the control vessel 5, and an opening / closing valve lid 9 is provided outside the outlet 8. The outlet 8 is for allowing water in the control container 5 to flow out in a short time during small washing, and has a predetermined height from the bottom surface in the tank body 1, that is, the water level in the tank body during small washing. It is open to the lowest level. On the other hand, the opening / closing valve lid 9 provided at the outlet 8 is formed in a plate shape as shown in FIGS.
An outlet 8 is provided in the side wall so as to be applied from the outside. A guide shaft 91 extending vertically downward is provided on both sides of the valve lid 9. The guide shaft 91 is inserted into sliding holes 92 provided vertically along both sides of the outlet 8. On the other hand, by slidably inserting from above,
The outlet 8 is slid up and down to close the outlet 8 freely. Normally, the above-mentioned on-off valve lid 9 maintains the valve-closed state by its own weight, but the connecting member 11 connected to the upper part is lifted up by the turning operation of the operation handle 4 to rise and open, and the above-mentioned connecting is performed. When the member 11 becomes loose, the member 11 descends again by its own weight and closes the outlet 8.

The guide shaft 91 slides so as to be inserted into the sliding hole 92 when the on-off valve lid 9 is lowered. The lower end of the sliding hole 92 is narrowed to a small diameter. As the 91 descends inside the sliding hole 92, water filling the sliding hole 92 gushes to the outside through the small diameter hole 93, and at this time, an appropriate resistance is generated, and the on-off valve cover 9 is closed.
Descent is delayed. In addition, the above-described resistance is provided by providing an appropriate clearance between the guide shaft 91 and the sliding hole 92 without providing the small-diameter hole 93, and through this clearance, the water between the inside of the sliding hole 92 and the outside is provided. It can be generated even if it is configured to enter and exit.
Accordingly, the opening / closing valve lid 9 is raised by the operation of the operation handle 4, and thereafter, when the opening / closing valve lid 9 closes due to its own weight, the guide shaft 91 descends from the inside of the sliding hole 92 through the small diameter hole 93 due to the lowering of the guide shaft 91. I do. At this time, the guide shaft 9
1 produces the necessary resistance which causes the on-off valve lid 9 to slowly descend over time. A small through hole 16 is formed in the bottom surface of the control container 5. The small through holes 16 are used for draining the water in the control vessel 5 little by little to lower the float 7 in the vessel 5 over time. The diameter is set so that the water can flow out for a predetermined time until the water is lowered to the position where the float 7 is lowered, for example, the time from the start of the drainage of the washing water in the tank body to the complete termination of the drainage.

The operating handle 4 provided on the upper part of the peripheral wall of the tank body 1 has a rotating shaft 41 extending horizontally into the tank body 1 and a lever 42 projecting downward. By being inserted into the support cylinder 11 fitted to the peripheral wall from the outside, it is supported so as to rotate left and right by a predetermined angle. The rotation direction of the operation handle 4 is determined in accordance with the large washing and the small washing.
When the handle 4 is turned to the left and the handle 4 is turned to the left, the large washing is performed. When the handle 4 is turned to the right, the small washing is performed.

Rotating shaft 4 extending horizontally in tank body 1
A rotating pipe 61 is fitted on the outer periphery of the arm 1, and an arm piece 62 for lifting the drain valve body 31 and a lifting arm piece 63 for lifting the on-off valve lid 9 are attached to the rotating pipe 61, respectively, facing downward. . The connecting member 10 made of a chain or the like is hung on the arm piece 62,
The lower end of the connecting member 10 is connected to the upper end of the overflow pipe 15 without slack. In addition, the lifting arm 6
Reference numeral 3 denotes a fixed piece 64 fixed to the outer periphery of the rotating pipe 61 and a rotating piece 66 pivotally supported at an intermediate portion of the fixed piece 64 via a rotating shaft 65.
The locking piece 67 is formed to bend at one side of the tip of the fixed piece. Then, the above-described rotating piece 66
The connecting member 11 is hung from the tip of
The lower end of 1 is connected to the upper part of the opening / closing valve lid 9 in a slightly slack state. Therefore, when the operation handle 4 is turned to the large side, as shown in FIG.
The connecting member 11 is pulled up to a small size in a form in which.
In this raising, the opening / closing valve lid 9 is kept closed only by loosening the connecting member 11 because the lifting stroke is small. When the operation handle 4 is turned to the small side, the fixed piece 64 is turned by a predetermined angle and the locking piece 67 is turned.
The pivoting piece 66 locked by the pivot member 66 is pivoted so as to extend the fixed piece 64, whereby the connecting member 11 is pulled up with a large stroke, and the on-off valve lid 9 is opened.

Next, the operation of the toilet flushing tank device a configured as described above will be described. Normally, the cleaning water is stored in the tank main body 1 to the upper limit level in the tank main body 1 by water supplied by the ball tap water tap 2. In this state, the drain valve 3 is closed by water pressure,
Further, the on-off valve 9 is kept closed by its own weight.

At the time of large cleaning, the user operates the operation handle 4.
When the arm is turned to the large side, the arm piece 62 is turned by a predetermined angle as shown in FIG. 6B, and by this turning, the connecting member 10 and the overflow pipe 15 are pulled up, and the drain valve body 31 is opened. I do. From this point, the supply of the wash water from the tank body 1 to the toilet is started (FIG. 3). Further, the drain valve body 31 that has been once opened rises by the buoyancy of the float 7 and maintains the valve open state. At the same time as the rotation of the arm 62, the lifting arm 63 rotates as shown in FIG. 6B, whereby the connecting member 11 is pulled up with a small stroke. However, in the above-described stroke, the on-off valve cover 9 is not pulled up only by stretching the loosened connecting member 11, and the closed state is maintained.

When the water level in the tank main body 1 decreases with the drainage of the washing water and drops to the opening at the upper end of the control container 5, the washing water in the tank main body 1 does not flow into the control container 5, and the tank The washing water in the main body 1 is drained in a large amount from the drain port 32, and the water level rapidly drops. In parallel with this, water in the container 5 also flows out of the small through hole 16 on the bottom surface of the control container 5 and the float 7 also descends, but the amount of outflow from the small through hole 16 is small. The water level drops slowly and falls slowly over time. Therefore, all the washing water in the tank body 1 is drained until the float 7 descends to the lower part in the control vessel 5 and the drain valve 31 is seated in the drain 32, and the drain is completed. are doing. That is, during the large washing, all the water in the tank body 1 is drained. After the drain valve 3 is closed, water is supplied from the ball tap water tap 2 in the upper part of the tank body 1, and the washing water is supplied to the upper limit water level in the tank body 1.

When the operation handle 4 is turned to the small side during small washing, the arm 63 is turned by a predetermined angle, the drain valve body 31 is pulled up via the connecting member 10, the drain valve 3 is opened, and the toilet bowl is opened. Water supply to is started. At the same time, the lifting arm 63 rotates to the state shown in FIG. 6 (a), whereby the connecting member 11 is largely lifted and the on-off valve lid 9 is opened (FIG. 4). When the water level in the tank body 1 decreases with the drainage and drops below the opening at the upper end of the control vessel 5, the outlet 8 in the side wall of the control vessel 5 is greatly opened, so that the water in the control vessel 5 flows. It quickly flows out through the outlet 8, and the water level in the container 5 also drops rapidly at substantially the same speed as the water level drop in the tank body 1. The opening / closing valve lid 9 starts to descend by its own weight at the time when the hand is released from the turned operation handle 4. However, as described above, resistance is generated as the guide shaft 91 descends. Descend slowly. Therefore, the outlet 8 is closed by the on-off valve lid 9 after the drain valve 3 is closed.

When the float 7 in the control vessel 5 descends to the lower part of the vessel 5 and the water level in the tank main body 1 drops to the lower limit level in the small washing, the drain valve body 31 descends together with the float 7. The operator sits on the drain port 32 and closes the valve. Drain valve 3
When the valve is closed, flush water remains in the tank body 1 in a range below the outlet of the control vessel 5, and the amount of flush water supplied to the toilet is reduced by the amount of the residual water. Will be.

As described above, in the toilet flushing tank apparatus a, the supply of the flush water to the toilet is performed only by the control vessel 5 without the need to double the vessels around the drain valve as in the conventional apparatus. The amount can be switched selectively.
Therefore, the structure can be simplified, and the external shape of the control container 5 provided around the drain valve 3 can be made compact, so that the space inside the tank body 1 can be effectively used. In addition, in the above-mentioned toilet bowl washing tank device a, the small through hole 16 is opened in the bottom wall of the control container 5, but the small through hole may be provided in any form as long as it is located below the control container 5. For example, as shown in FIG. 9 and FIG. 9 has a small through hole 16 formed in the lower center part of the on-off valve lid 9, and the one shown in FIG. A small through-hole 16 communicating with 8 is formed.

The small through-hole 16 is closed by being pulled by the member 11 and swung to the open side. Conversely, when the lifting arm 63 is turned to the large side, the open / close valve lid 29 that has moved to the open side returns to the close side again, and closes the outlet 8 by its own weight.
Note that the small through holes 16 described above may be provided on the bottom surface of the control container 5 in the same manner as described above.

The on-off valve cover 39 shown in FIG. 8 is protruded from one end of the lower side, and a projection 391 is pivotally mounted on a side wall 5a of the control vessel 5 by a support shaft 392, so that the on-off valve cover 39 is closed. It is supported rotatably along the vertical side wall 5a. The lower end of the connecting member 11 is connected to the other end of the lower side of the on-off valve lid 39. The opening / closing valve lid 39 is pulled by the connecting member 11 and turned to the open side by turning the raising arm piece 63 to the small side by the turning of the operation handle 4, and is turned to the small through hole 16.

On the other hand, when the operation handle 4 is turned and the lifting arm 63 is turned to the large side, the opening / closing valve cover 39 maintained on the open side is turned to the closing side to close the outlet 8 again. Has become.

In the embodiment shown in FIGS. 11 and 12, a rectangular outlet 8 is opened on the bottom surface of a control container 5 'formed in a substantially rectangular plane, and the outlet 8 is provided with an on-off valve located on the lower surface thereof. It is closed by a lid 49 so that it can be opened and closed freely. The on-off valve lid 49 is a rectangular plate slightly larger than the outflow port 8, and has both short sides inserted into a sliding groove 42 a formed between the guide side 42 and the bottom surface of the control container 5 ′. It is slidably supported in the short side direction, and is supported so as to move between a closed position for closing the outlet 8 and an open position for releasing.
Further, the small hole 16 is opened substantially at the center of the on-off valve cover 49 located within the range of the outlet 8. The shape of the control container 5 'and the shapes of the outlet 8 and the opening / closing valve lid 49 are not limited to those in the above-described embodiment, but can be changed to any shapes.

As shown in FIGS. 13 and 14, the ends of the piston rod 41b of the damper 41 are fixed to both ends of the long side of the on-off valve lid 49. Both dampers 41 are
A piston rod 41b connected to the on-off valve lid 49 side is slidably fitted into a hollow cylindrical cylinder 41a attached and fixed to the bottom surface of the control container 5 ', and a half of the cylinder 41a is inserted. The piston rod 41b is constantly urged in the direction of extension by the restoring force of the coil spring 41c. That is, the opening / closing valve lid 49 is pulled toward the closing side by the urging force of the coil spring 41c. A small hole 41d communicating the inside of the cylinder 41a with the outside is formed in the rear end surface of the damper 41. When the piston rod 41b contracts, the small hole 41d is formed.
1d, water flows into the cylinder 41a, and when extended, water in the cylinder 41a flows out of the small hole 41d. When the water flows in and out of the small hole 41d, the resistance of the piston rod is reduced. 41b acts as a resistance to delay the extension. Also, a pulley 43 is provided on one side of the bottom surface of the control container 5 ',
The connecting member 11 extending from the arm piece 63 is connected to the pulley 43

In the device configured as described above, when the operating handle 4 is turned to the large side, the connecting member 11 is pulled up small. However, this pulling-up stroke is so small that the connecting member 11 can only be loosened. Thus, the on-off valve lid 49 is maintained in the closed state (FIG. 11). When the operation handle 4 is turned to the small side, the connecting member 1 is rotated.
1 is pulled up with a large stroke, the on-off valve lid 49 slides to the open position, and the outlet 8 is opened. On this occasion,
The piston rods 41b of both dampers 41 are forcibly extended, and water flows into the cylinder 41a through the small holes 41d (FIG. 12). The opening / closing valve lid 49 is released from both the dampers 4 when the hand is released from the turned operation handle 4.
The movement of the piston rod 41b is started toward the closing side by the urging force of the first coil spring 41c. However, as described above, the return of the piston rod 41b takes a long time due to the resistance of water generated when flowing out through the small hole 41d. 8 is closed by the on-off valve lid 49 after all the water in the tank body 1 is supplied and the drain valve 3 is closed. The time required for the on-off valve lid 49 in the open position to close the outlet 8 is
It can be arbitrarily set by changing the size of the small hole 41d of the damper 41, the number of the spring strips of the coil spring 41c, or both.
