2. Description of the Related Art Conventionally, as a toilet bowl cleaning tank device of this type, for example, as disclosed in Japanese Patent Application Laid-Open No. 7-11680, a water storage tank for storing cleaning water and a bottom of the water storage tank are attached and opened. And drain the wash water and store the wash water when the valve is closed, and when the drain valve is opened, the wash water is drained and buoyancy is applied to the drain valve to open it. A float, a control container having a small hole and an outlet through which the float and the float and the washing water for obtaining the buoyancy are stored and through which the stored washing water flows out; and an opening / closing valve lid for opening and closing the outlet. , Some have operating means for opening the drain valve and selectively opening and closing the on-off valve lid.

In this toilet bowl cleaning tank device, when the drain valve is opened with the on-off valve lid closed, the drain valve is kept open by the buoyancy of the float accommodated in the control container. Is continuously drained. When the washing water stored in the control container also flows out from the small through hole, the float loses its buoyancy, so the drain valve is closed and the washing water is drained. On the other hand, if the drain valve is opened with the on-off valve lid open, the drain valve is kept open due to the buoyancy of the float accommodated in the control container, as with the on-off valve lid closed. Wash water is continuously drained. In this case, the flush water loses buoyancy earlier than the state in which the opening / closing valve lid is closed because the wash water stored in the control container flows out from the small through hole and the outlet, so the drain valve also closed the opening / closing valve lid. The valve closes earlier than the state. As a result, the amount of drainage becomes smaller than in the state where the on-off valve lid is closed.

In this type of toilet bowl cleaning tank device, the drainage amount of a plurality of flush water can be controlled by a single drain valve.
It is possible to obtain almost the same instantaneous drainage flow rate with different drainage volumes.

[0005]

However, in the conventional toilet bowl cleaning tank device, the opening and closing of the outlet of the on-off valve lid is performed by sliding the on-off valve lid, so that the watertightness when the on-off valve lid is closed. Alternatively, since the open / close valve lid has poor slidability, the outflow of the washing water contained in the control container varies. As a result, a difference occurs in the duration of the buoyancy applied to the drain valve for each drain of the wash water, so that there is a problem that a predetermined amount of drainage cannot be stably obtained. Therefore, it is an object of the present invention to provide a toilet bowl cleaning tank device capable of stably obtaining a predetermined amount of drainage while securing substantially the same instantaneous drainage flow rate even with different amounts of drainage.

[0006]

In order to solve the above problems, the toilet bowl cleaning tank device of the present invention is provided with a water storage tank for storing cleaning water and a bottom portion of the water storage tank. A drain valve that opens and closes a drain port, an operating means that opens the drain valve, and a buoyancy force is applied to the drain valve until the wash water is drained and reaches a predetermined water level when the drain valve is opened. A float that is opened by a valve, a control container that accommodates the float and that has a plurality of communication holes at the bottom that communicates with the water storage tank, and a valve body that opens and closes at least one of the plurality of communication holes. In a toilet bowl cleaning tank device including valve body operating means for opening and closing the valve body, the valve body has a weight that overcomes the buoyancy of the cleaning water in the control container and is placed in the communication hole. The communication hole is closed by It is characterized in. By doing so, not only the weight of the valve body but also the head pressure of the wash water contained in the control container can be used to close the outlet, so that the watertight state can be more reliably achieved. It is possible to more stably obtain the drainage amount of the cleaning tank device.

In a preferred aspect of the present invention, a portion of the valve body that closes the communication hole has a spherical shape, and the communication hole opened and closed by the valve body has a circular shape. By doing so, the valve body smoothly moves by the weight of the valve body and closes the communication hole even if the valve body is not reliably placed in the communication hole, so that the configuration and structure of the valve body can be simplified. Is possible.

Further, as a preferred aspect of the present invention, the valve body and / or the portion of the communication hole where the communication hole is closed by the valve body is formed of an elastic body that is elastically deformed. By doing so, it is possible to further improve the adhesion between the valve body and the communication hole, so that it is possible to obtain a more stable drainage amount of the toilet bowl cleaning tank device, and there is fine dust in the communication hole. Can also be reliably sealed with the valve body.

Further, as a preferred aspect of the present invention, the valve body operating means is operated by the operating means. By doing so, the drain valve can be opened and the communication hole can be opened and closed by operating the operating means once, and the operation is simplified.
