DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an opening / closing structure of a valve body that is opened / closed for discharging flush water in a flush tank that supplies flush water to a toilet bowl.

(Prior art and its problems) Conventionally, a ball valve or the like is arranged in a low tank that stores flush water so that it can be opened and closed in order to discharge flush water to the toilet side. The chain is connected, and the chain is pulled up by the operation of the lever arranged outside the low tank to open and close the ball valve, and the flush water is discharged to the toilet bowl. In order to change to a structure that can be operated mechanically, a motor or rotary solenoid is required to pull or wind up the chain connected to the ball valve, and in order to operate such a motor or rotary solenoid, Large electric capacity is required. If a battery is provided in the low tank and electric power is supplied from the battery to operate the motor or rotary solenoid from the viewpoint of preventing accidents such as electric shock, the electric capacity of the motor or rotary solenoid is large as described above. Therefore, there is a problem that the capacity of the battery becomes insufficient, the battery cannot be used for a long time, and the battery needs to be replaced frequently.

(Means for Solving the Problem) The present invention has been devised in view of the above conventional problems, and an object thereof is not to submit a cleaning tank device that can open and close a valve favorably with a small amount of electric power. The gist includes a tank for storing cleaning water, a water supply mechanism for supplying the cleaning water into the tank, and a valve body arranged in the tank and opened / closed for discharging the cleaning water to a toilet bowl. In the toilet bowl cleaning tank device, a floating body is disposed above the valve body so as to be connected to the valve body, and a tubular body is erected around the floating body, and a portion of the tubular body below the floating body and the water supply mechanism. Is connected via an electromagnetic valve, and high-pressure water is introduced from the water supply mechanism into the cylindrical body by the opening / closing operation of the electromagnetic valve to raise the floating body to open / close the valve body.

(Function) A floating body is arranged above the valve body that opens and closes the discharge of the wash water in a connecting manner via a connecting member, and a cylindrical body is erected around the floating body. Since the inside of the and the water supply mechanism such as a ball tap are connected via a solenoid valve,
By operating the solenoid valve and supplying high-pressure water from the water supply mechanism to the cylinder, high-pressure water is supplied to the cylinder, and the high-pressure water causes the floating body to rise, and the valve body rises as the floating body rises. Since the drain port can be opened and the valve body is not pulled up by a motor or rotary solenoid as in the past, the valve body is opened by using the pressure of tap water, etc. It is necessary only for opening and closing the valve, and the valve element can be opened and closed with extremely low power.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an arrangement configuration diagram in the raw tank of the first embodiment, and FIG. 2 is an enlarged configuration diagram of a main part of FIG.

In the figure, washing water can be stored in a low tank 1 which is erected on the rear upper surface side of the toilet bowl, and the washing water is leveled by a ball tap 2 provided with a float 3 fixed inside the side wall of the low tank 1. The float 3 floats as the water level rises, and the ball tap 2
Can be closed. A water supply pipe 4 is connected to the ball tap 2 via a connection pipe 5, and the water supply pipe 4 is connected to an external water pipe or the like. In addition, a drain port is provided on the bottom side of the low tank 1 for discharging cleaning water to the toilet side.
1a is formed, and a valve seat 7 is arranged on the upper surface side of the drainage port 1a, and an overflow pipe 6 is continuously connected to the valve seat 7 in a rising shape.

In this example, as shown in FIG. 2, a tubular guide cylinder 12 and a locking cylinder 13 are fixedly installed on the overflow pipe 6 via fixing bands 16 and 16, and the guide cylinder 12 is located above. Is open, and the lower part of the locking cylinder 13 is open. The guide cylinder 12 and the locking cylinder 13
Is the one integrally formed through the partition wall 14.
A water hole 15 penetrating in the vertical direction is formed in the central portion of 14. A spherical ball valve 8 is in contact with the upper portion of the valve seat portion 7, and the ball valve 8 normally closes the valve seat portion 7 so that the drainage port 1a is closed.

In this example, a floating body 10 is connected to the ball valve 8 via a rod-shaped or chain-shaped connecting member 9 so as to be connected upward, and the floating body 10 is arranged in the guide cylinder 12 so as to be vertically movable. It is a thing. Further, the connecting member 9 is arranged through the water hole 15, and the ball valve 8 can be engaged with the lower end portion of the engaging cylinder body 13 in an abutting manner. Further, in this example, a pressure guiding pipe 17 is connected to the lower portion of the guide cylinder 12 from the outside so that the pressure guiding pipe 17 is connected to the ball tap 2 side via an electromagnetic valve 18. Has been done. The solenoid valve 18 is electrically connected to an operation switch 19 attached to the side wall surface of the low tank, for example, and the operation switch 19
When the user turns ON the valve 19, the solenoid valve 18 is opened for about 2 seconds, for example.

In such a configuration, when the user wants to flush the wash water after defecation, the operation switch 19 is turned on, so that the solenoid valve
When 18 is opened for 2 seconds, tap water passing through the water supply pipe 4 is guided through the passage in the ball tap 2 into the pressure guiding pipe 17,
The guided tap water is high-pressure water, and the guide cylinder 12
The floating body 10 is vigorously flowed in and the floating body 10 arranged in the guide cylinder 12 is vigorously raised. Therefore, as the floating body 10 rises, the ball valve 8 is pulled up by the connecting member 9 to rise from the valve seat portion 7, the drain port 1a is opened, and the flush water flows out to the toilet side. After 2 seconds, the supply of tap water via the pressure guiding pipe 17 stops, so that the floating body 10 gradually descends in the guide cylinder 12, and at that time, the water in the guide cylinder 12 gradually passes through the water hole 15. It slowly flows downward, and the ball valve 8 gradually descends accordingly, and after a certain period of time, it contacts the valve seat 7 and closes the drain port 1a. During this time, the wash water is discharged from the drain port 1a to the toilet side.

In this example, the high-pressure primary side pressure of tap water on the side of the water supply pipe 4 is used as an operating force for levitating the floating body 10 in this way, and only the solenoid valve 18 is electrically operated. It suffices to open and close the ball valve 8 with extremely small electric power, and even if the solenoid valve 18 is operated by a dry battery or the like, the electric life is extended for a very long time.

In the figure, 11 is a lifting chain connected to the upper part of the floating body 10, and this lifting chain 11 is connected to a manual lever attached to the wall surface of the raw tank or the like as in the conventional case. That is, even if it is manually operated, the floating body 10 is pulled up and the ball valve 8
It is possible to open and close.

Next, FIGS. 3 and 4 show a second embodiment.

The same members as those in the first embodiment are designated by the same reference numerals and will be described.

In this example, a piston type valve is used instead of the ball valve 8, and the triangular packing 21 is provided on the bottom surface of the low tank 1.
A valve seat portion protruding from the upper surface of the drain metal fitting 22 is fixed by fixing the drain metal fitting 22 that constitutes the drainage port via the tightening nut 20 and the tightening nut 20.
A flat plate-shaped valve body 25 that opens and closes the drainage port 22b of the drainage fitting 22 by abutting against the 22a is provided, and a cylindrical fixed tubular body 23 is fixed to the outer peripheral portion of the upper surface side of the drainage fitting 22. Everything, this fixed cylinder
The overflow pipe 24 is inserted into the center of the partition wall 23a of 23.

Above the partition wall 23a of the fixed tubular body 23, a flat plate-like floating plate 26 is fixedly arranged horizontally on the outer peripheral portion of the overflow pipe 24, and the floating tubular body 23 is floated. The pressure-conducting pipe 17 is connected to the lower portion of the plate 26 from the outside in a communication manner,
The pressure guiding pipe 17 is connected in communication with the ball tap 2 via the electromagnetic valve 18 similar to that of the first embodiment. A gap S is formed between the outer circumference of the overflow pipe 24 and the inner circumference of the partition wall 23a. Reference numeral 27 in FIG. 3 denotes an operation lever for manual operation fixed to the side wall surface of the low tank 1, which is connected to the upper end of the overflow pipe 24 through a chain or the like. Also, the overflow pipe 24 is raised and the valve body 25 is raised to raise the drainage port.
22b can be opened and closed.

Also in this example, when the user turns on the operation switch 19, the solenoid valve 18 is opened, the high-pressure water on the primary side is introduced into the fixed cylindrical body 23 via the pressure guiding pipe 17, and the pressure of the high-pressure water is increased. As a result, the floating plate 26 is lifted up, and as shown in the right half of the center line in FIG. 4, the floating plate 26 is guided by the fixed cylindrical body 23 and ascends, and the overflow pipe 24 ascends at the same time. The valve body 25 at the lower end thereof is lifted to open the valve seat portion 22a, and the wash water is drained to the toilet side through the drain fitting 22. Also, after the water pressure from the pressure guiding pipe 17 is stopped after about 2 seconds, the floating plate 26 and the overflow pipe 24 gradually descend,
At this time, water is released through the gap S and the floating plate 26 descends favorably, and along with this, the valve body 25 also gradually descends, and after a certain time, the valve body 25 contacts the valve seat 22a and the drainage port Close 22b.

In the first and second embodiments, as shown in FIGS. 1 and 3, the solenoid valve 18 is connected to the direct water supply pipe 4
The same effect can be obtained even if the tap water is directly connected to the connecting pipe 5 through the solenoid valve 18 and connected to the connecting pipe 5. It suffices that the 26 and the like can be floated by high-pressure water such as tap water on the primary side, and the ball valve 8 or the valve body 25, etc. can be lifted accordingly, and the opening / closing operation of the wash water can be performed.
