Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tank for supplying flush water to a toilet bowl, and more particularly to a tank for supplying a small amount of water continuously to a toilet bowl to prevent freezing of trapped water and the like. About the tank.

[0002]

2. Description of the Related Art In a cold region toilet, a flow valve is provided in a tank such as a low tank, and water is supplied little by little to the toilet to prevent freezing of trap water.

FIG. 5 is a sectional perspective view of a conventional low tank provided with the flow valve.

A main body 16 of the float valve device 14 is fixed to an opening 12 on the bottom surface of the low tank 10 by a nut 18. This float valve device 14
Is provided with a valve element 20 which is pulled up via a chain or the like by a lever handle (not shown) at the upper portion of the valve. The main body 16 has a seat portion on which the valve body 20 sits on its upper surface. From the main body 16 to the overflow pipe 2
2 are erected. Further, a hose 24 connected to the main body 16 is connected to a flow valve 26 attached to a side wall of the low tank 10. By turning the handle 28 of the flow valve 26 to open the valve, the water in the low tank 10 flows into the main body 16 from the inflow port 30 of the flow valve 26 through the hose 24, and continuously flows toward the toilet. It is supplied little by little (for example, 100 liter / Hr).

The flow valve 26 includes a substantially cylindrical casing, a spindle (not shown) inserted into the casing, and the handle 28 mounted on the spindle.
Etc. The flow valve 26 is inserted into an opening penetrating through the side surface of the raw tank 10, and is fixed to the raw tank 10 by tightening a nut via a packing.

The inner peripheral surface of the casing is provided with a female screw,
A male screw on the outer peripheral surface of the spindle is meshed with the female screw. By turning the handle 28, the spindle advances and retreats in the direction of the axis thereof, and communication between the inlet 30 and the hose 24 is established and cut off. .

[0007]

As described above, since the flow valve 26 is for receiving the water in the low tank 10 from the inlet 30 and flowing it to the hose 24, the flow valve 26 is naturally positioned lower than the full water level. . Therefore, since the low tank opening for mounting the flow valve 26 is always located below the water surface, there is a risk that water will leak if the packing is deteriorated or the nut is loosened.

It is a first object of the present invention to provide a tank with a flow valve which can reliably prevent such water leakage from a low tank.

In the above-described conventional flow valve, since the flow rate gradually increases as the handle 28 is turned in the opening direction, the user stops the handle 28 in an attempt to save the flowing water. It may stop at an odd opening position. In such a case, the amount of flowing water becomes as small as, for example, about 30 L / Hr, and it may not be possible to prevent the toilet from being frozen.

According to the present invention, there is provided a tank with a flow valve capable of reliably preventing freezing of a toilet bowl without performing a halfway open state, in which the flow valve performs only two operations of full opening and full closing. The second purpose is to provide.

[0011]

According to the first aspect of the present invention, there is provided a tank with a flow valve, comprising: a tank having a float valve at a bottom portion; and a flow valve communicating with a secondary side of the float valve. The flow valve is a tank with a flow valve that is disposed below a full water level in the tank. The flow valve includes a remote control member that controls the flow valve remotely by disposing the flow valve only inside the tank. It is characterized by the following.

In such a tank with a flow valve, the flow valve is arranged only in the tank, and since there is no opening for mounting the flow valve in the tank wall, water leakage from the opening cannot occur. Become.

[0013] The tank with the flow valve according to the second aspect is the first aspect.
In the above, the flow valve, a seat portion provided in the water channel,
A valve body that is seated on the seat portion; and a spring that urges the valve body in a seating direction. The remote control presses the valve body to separate it from the seat portion, and advances the cable. Cable stopping means for stopping only at two positions, a position and a retracted position.

In such a tank with a flow valve, it is possible to perform only two operations: a fully closed state in which the valve body is seated on the seat portion, and a fully opened state in which the valve body is separated from the seat portion by a predetermined distance. An odd half-open state is prevented. Therefore, when the flow valve is opened to prevent freezing, the flow valve is always fully opened, and freezing is reliably prevented.
