Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a water storage tank for storing wash water, a drain valve provided at the bottom of the water storage tank, operating means for opening the drain valve, and the drain valve opened. The present invention relates to a toilet bowl cleaning tank device provided with a float that gives a buoyancy force to a drain valve until the flush water is drained and reaches a predetermined water level to open the valve.

[0002]

2. Description of the Related Art Heretofore, as a toilet bowl cleaning tank device of this type, as disclosed in, for example, Japanese Patent Application Laid-Open No. 7-11680, a water storage tank for storing cleaning water and an opening attached to the bottom of the water storage tank have been opened. When the valve is drained, the wash water is drained, and when it is closed, the wash water is stored, and when the drain valve is opened, the wash water is drained and the drain valve is opened by giving buoyancy until it reaches a predetermined water level. Float to be in a state, a floating container and a control container containing a wash water for obtaining buoyancy and a small through hole and an outlet for letting out the stored wash water, and an opening / closing for opening and closing the outlet There is a valve lid and an operating means for opening and closing the drain valve and selectively opening and closing the on-off valve lid.

In the 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. Water is continuously drained. When the wash 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 drain of the wash water is completed. 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, since the opening and closing of the outlet of the on-off valve lid is performed by sliding the on-off valve lid, the watertightness or the opening and closing when the on-off valve lid is closed. The slidability of the valve lid is poor, and the outflow of washing water stored 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, a toilet cleaning tank device according to claim 1 is provided with a water storage tank for storing cleaning water and a bottom portion of the water storage tank. Drainage valve that opens and closes the drainage port,
Operating means for opening the drain valve, and a plurality of floats for applying buoyancy to the drain valve until the drain water reaches a predetermined water level when the drain valve is opened to open the drain valve. And a selection means for selecting the number of the plurality of floats in order to adjust the buoyancy acting on the drain valve. By doing so, you can change the buoyancy applied to the drain valve by selecting the number of multiple floats,
As a result, the opening time of the drain valve can be switched. In addition, depending on the installation position of the plurality of floats, it is possible to switch the closing water level of the drain valve by detecting the water level of the water storage tank, and it is possible to control a plurality of different flush water discharge amounts from one drain valve. Further, since the same drain valve drains the wash water from the same drain port, it is possible to obtain almost the same instantaneous drainage flow rate even with different drainage amounts, and the valve is unstable as in the conventional example. It is possible to control the opening time of the drain valve by switching the buoyancy of the float or detecting the water level of the water storage tank regardless of the watertightness, so it is possible to suppress the difference in the duration of buoyancy given to the drain valve for each drain of wash water, It is possible to stably obtain a predetermined amount of wastewater.

As a preferred embodiment of the present invention, a container for accommodating at least one float of a plurality of floats is arranged in the water storage tank, and a communication hole communicating with the water storage tank is formed in the container. The opening area of the communication hole was set so that the decrease in the level of the wash water in the container was delayed compared to the decrease in the level of the wash water in the water storage tank. By doing so, it is possible to close the drain valve after the wash water in the water storage tank is almost drained, and the amount of wash water remaining in the water storage tank when the drain valve is closed can be reduced.
In addition, since the capacity of the water storage tank can be effectively utilized, it is possible to relatively reduce the capacity of the water storage tank, and the area of the communication hole in the container is set so that the water level is gently drained as the water level of the wash water decreases. Since the valve is closed, it is possible to prevent the generation of noise due to sudden closing.

Further, in a preferred aspect of the present invention, the selecting means is operated by the operating means. By doing so, different drainage amounts can be obtained by operating the operating means once, and the operation becomes simple.

The water storage tank 1 is formed of a synthetic resin such as polypropylene into a box shape having an open top surface. The bottom surface of the water storage tank 1 is provided with a drain port 2 and the upper side surface thereof is provided with a mounting hole for mounting the operating portion 10. It has been opened. Also,
A control container support portion 5 that supports the control container 4 extending in the vertical direction is integrally formed around the drainage port 2. The control container support portion 5 is provided with a predetermined distance from the drain port 2 and has a relatively widthwise dimension in order not to significantly affect the flow of the wash water drained from the drain port 2. It has been made smaller.

The free float 9 is made of synthetic resin such as polypropylene and is formed into a hollow shape or a foamed shape, and a part of the free float 9 can be brought into contact with the regulating portion 14 so as to be in contact with the control container 4.
Protruding from the upper end of. The fixed float 8 is also made of synthetic resin such as polypropylene and is hollow or foamed. The fixed float 8 is located outside the control container 4 and inside the water storage tank 1, and its upper portion is fixed to the drain valve 3. .

The drain valve 3 is made of a synthetic resin such as ABS, and is a cylindrical hollow overflow for draining the wash water in the water storage tank 1 when the water level becomes abnormally high for some reason. It has a tube in the center. In addition, a structure in which a seal packing for ensuring a sealing property can be attached to a portion in contact with the drainage port 2, and the valve can be opened by the buoyancy of the fixed float 8 and the free float 9 when the operation unit 10 is operated. Thus, it is inserted in the central portion of the control container 4.

FIG. 2 is an external view of the operation unit 10, and FIG.
It is a PP sectional view of FIG. The operation unit 10 includes an operation lever 11
And an operating shaft 12 connected to the operating lever 11, and an operating shaft 1
A ball chain locking portion 13 that locks the ball chain 7 at the tip of 2 is formed. The restriction portion 14 is rotatably fitted on the operation shaft 12. The restricting portion 14 is composed of a fitting portion 14a fitted to the operation shaft 12 and a protruding float holding portion 14c for restricting the rising of the free float 9, and the fitting portion 14a
Has a half-shaped portion 14b formed in one half on the side of the operating lever 11. The operation shaft 12 is provided with a pin 15 that is locked to the half-shaped portion 14b when the operation shaft 12 rotates in the X direction (clockwise direction). FIG. 3A shows the operation lever 11
This is the state before operating. At this time, the float holding part 14c
Has its tip vertically positioned by its own weight and holds the free float 9 so that it does not float.

FIG. 3B shows a section taken along the line PP when the operating lever 11 is operated in the large washing direction (X direction). When the operating lever 11 is rotated in the large washing direction, the drain valve 3 is opened by the ball chain 7 shown in FIG. 1, and the pin 15 fixed to the operating shaft 12 shown in FIG. 3B is moved in the same direction. When rotated, the restricting portion 14 is locked in the half-shaped portion 14b to rotate in the same direction as the operation shaft 12, and the float holding portion 14c also rotates in the same direction. At this time, the tip of the float holding portion 14c shown in FIG. 1 separates from the free float 9, and the free float 9 floats up and comes into contact with the float receiver 16 provided on the drain valve 3 to give the drain valve 3 buoyancy. The buoyancy of the fixed float 8 and the free float 9 is applied to the drain valve 3. The state is shown in FIG.

When the drain valve 3 is opened, the washing water in the water storage tank 1 is drained, the water level in the water storage tank 1 is lowered and the buoyancy of the fixed float 8 is lost, but the free float 9 contained in the control container 4 is removed. The drainage valve 3 is kept open by buoyancy, so that the wash water is continuously drained. When the wash water stored in the control container 4 eventually flows out from the communication hole 6, the free float 9 loses its buoyancy, so that the drain valve 3 is closed and the drain of the wash water is completed. As a result, all the wash water in the water storage tank 1 is drained.

FIG. 3 (c) is a sectional view taken along the line PP when the operating lever 11 is operated in the small washing direction (Y direction). When the operation lever 11 is rotated in the small washing direction (Y direction),
The drain valve 3 is opened by the ball chain 7 shown in FIG.
The pin 15 fixed to the operation shaft 12 shown in (c) also rotates in the same direction but does not come into contact with the float retainer portion 14c.
The float holding part 14c holds the same position as before the operation. That is, the tip of the float holding portion 14c shown in FIG.
The drain valve 3 is not buoyant. The state is shown in FIG.

The drain valve 3 maintains the open state only by the buoyancy of the fixed float 8, but the flush water in the water storage tank 1 is drained to lower the water level, and the drain valve 3 moves in the valve closing direction.
The drain valve 3 can be closed while the cleaning water in the water storage tank 1 remains depending on the setting position of the fixed float 8.

FIG. 6 shows an embodiment having another structure. Figure 7
FIG. 7 is a perspective view of only the drain valve 3, the fixed float 8 and the free float 9 in FIG. 6. The difference between the configuration of FIG. 6 and the configuration of FIG. 1 is that the fixed float 8 is located in the control container 4. Figure 6
The fixed float 8 in is located inside the control container 4 and above the free float 9, and a part of the upper part is fixed to the drain valve 3. Other configurations are the same as those in FIG.

The configurations and operations of the operating portion 10 and the regulating portion 14 are the same as those described above. If the operating lever 11 is
FIG. 8 shows the state when it is operated in the direction). When the operation lever 11 is rotated in the large washing direction (X direction), FIG.
The drain valve 3 is opened by the ball chain 7 shown in FIG.
The pin 15 fixed to the operation portion shaft 12 shown in (b) also rotates in the same direction and comes into contact with the float holding portion 14c, and the float holding portion 14c also rotates in the same direction. At this time, the tip of the float holding portion 14c shown in FIG. 6 separates from the free float 9 and the free float 9 floats up and comes into contact with the fixed float 8 to form an integral unit, which gives buoyancy to the drain valve 3. The buoyancy of the fixed float 8 and the free float 9 is applied to the drain valve 3.

When the drain valve 3 is opened, the wash water in the water storage tank 1 is drained, but the drain valve 3 is kept open by the buoyancy of the fixed float 8 and the free float 9 housed in the control container 4. Therefore, the washing water is continuously drained. When the wash water stored in the control container 4 eventually flows out from the communication hole 6, the fixed float 8 and the free float 9 lose their buoyancy, so the drain valve 3 is closed and the drain of the wash water is completed. As a result, all the wash water in the water storage tank 1 is drained.

FIG. 9 shows a state in which the operating lever 11 is operated in the small washing direction (Y direction). Operating lever 1
When 1 is rotated in the small washing direction (Y direction), the drain valve 3 is opened by the ball chain 7 shown in FIG. 6, and the pin 15 fixed to the operation shaft 12 shown in FIG. 3 (c) is also in the same direction. Although it rotates to the right, it does not come into contact with the float pressing portion 14c, so the float pressing portion 14c holds the same position as before the operation. That is, the tip of the float holding portion 14c shown in FIG. 6 does not separate from the free float 9 and does not give buoyancy to the drain valve 3.

The drain valve 3 holds the open state only by the buoyancy of the fixed float 8, and the drain valve 3 is kept open by the buoyancy of only the fixed float 8 housed in the control container 4, so that the washing water is not washed. It is continuously drained. When the wash water stored in the control container 4 eventually flows out from the communication hole 6, the fixed float 8 loses its buoyancy, so that the drain valve 3 is closed and the drain of the wash water is completed. However, since the buoyancy is smaller than that during the large cleaning, the drain valve 3 will be closed earlier than during the large cleaning. As a result, the set cleaning water remains in the water storage tank 1.

In this embodiment, one free float is provided, but the present invention is not limited to this, and the number of free floats may be plural. With two free floats, it is possible to select three levels of drainage, and by adding one free float to three, four levels of drainage can be selected. It is possible.
