BACKGROUND OF THE INVENTION
The present invention relates to a toilet flushing tank device that selectively switches the amount of washing water from a water storage tank to two stages and supplies it to a toilet.
[0002]
[Prior art]
Conventionally, as this type of toilet cleaning tank device, for example, there is a technique disclosed in Japanese Patent Laid-Open No. 9-88149. As shown in FIG. 1, this technology is a storage tank for storing cleaning water, and once the valve is attached to the storage tank and is opened, the cleaning water is drained and maintained in the open state by the buoyancy of the cleaning water. When the valve reaches a predetermined water level, the small cleaning valve body (second valve body) that is closed and the valve seat that the small cleaning valve body (second valve body) is seated and becomes watertight are attached to one end. It becomes a drainage passage for the small cleaning valve element (second valve element) and once opened, the cleaning water is drained and maintained in the open state by the buoyancy of the cleaning water, so that the cleaning water becomes a small cleaning valve element ( A valve device having a large cleaning valve body (first valve body) that is closed when the second valve body reaches a predetermined water level lower than the water level at which the valve is closed; and the small cleaning valve body A valve opening device for selectively opening the valve body (second valve body) and the large cleaning valve body (first valve body) is provided.
[0003]
The toilet flushing tank device is mechanically controlled by the buoyancy acting on the valve body because the amount of drainage of the wash water is relatively simple, and the water stoppage of the valve device is less than the weight of the valve body. Because it is performed by the head pressure of the wash water remaining in the water tank acting on the valve body and the negative pressure generated by the drainage of the wash water, it is highly reliable, and the valve opening device can select small washing or large washing Cleaning water can be saved.
[0004]
[Problems to be solved by the invention]
However, in the conventional toilet flushing tank device, when the same toilet flushing tank device is connected to the toilet bowl with different amount of washing water to be supplied and drainage performance, or the same large washing valve body is used for various toilet flushing tank devices In this case, if the small cleaning valve is opened and small cleaning is performed, the amount of cleaning water drained from the water storage tank will be larger than the amount of cleaning water flowing out from the bowl of the toilet bowl. On the other hand, the upstream side and the downstream side of the large washing valve body are filled with water. As a result, the head pressure of the washing water that has been acting to close the large washing valve element is not activated, and the large washing valve element may be opened due to the buoyancy of the washing water to perform large washing. There was a problem.
[0005]
In view of this, the present invention ensures that the valve body below the valve body disposed in the water tank is vertically overlapped, and the amount of washing water supplied to the toilet bowl and the drainage performance of the toilet bowl differ.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in FIG. 3, the water storage tank A is composed of a resin tank A1 formed of a synthetic resin, and a ceramic cover A2 provided so as to cover the outer surface of the resin tank A1. The device B is composed of a first valve body B1 and a second valve body B2 that are arranged one above the other, and these second valve bodies B2 are connected to the hinge shaft 34 provided on the first valve body B1 with the first valve body B1. The valve body B1 is attached to the hinge shaft 14 disposed at the bottom of the resin tank A1 so as to be swingable in the vertical direction, and is disposed on the first valve body B1 and the second valve body B2 and the upper part of the resin tank A1. The valve opening means C provided is linked via pulling members D1 and D2 such as ball chains, and the valve device by selectively raising the first valve body B1 and the second valve body B2 by operating the valve opening means C. B is opened.
[0013]
As shown in FIGS. 1 and 2, the second valve body B2 is formed in a hollow disc shape by a second valve body 20 formed in a flat plate shape with a synthetic resin such as ABS resin and a synthetic rubber such as EPDM. The packing 28 is used. The second valve body 20 has two second arms 25 on the side, a hook 21 for engaging the pull-up member D2 on the upper surface, and a packing fitting portion 22 for fitting a packing 28 on the lower surface. Each of these is provided integrally. A bearing recess 26 is formed in the end of the second arm 25 in a front inverted U shape from the lower end surface, and the hinge shaft 34 provided on the first valve body B1 is sandwiched by the bearing recess 26 to A single valve body B1 is swingably attached in the vertical direction. Since the packing fitting portion 22 is provided with a flange having a diameter larger than the diameter of the hollow portion of the packing 28, after the packing 28 is once elastically deformed and fitted into the packing fitting portion 22, the packing 28 is Does not fall off from the second valve body 20 due to its own weight. Since the second valve element B2 cannot have buoyancy by itself, the second valve element B2 is configured to obtain buoyancy by attaching a hollow float F to the pull-up member D2 engaged with the hook 21. Yes.
[0014]
As shown in FIGS. 1, 2 and 5, the first valve body B1 is integrally formed in a cylindrical shape having an upper surface and a bottom surface which are opened with a synthetic resin such as ABS resin, and is sealed from the outside along its peripheral side surface. The first annular valve body 30 is formed by integrally partitioning the annular float chamber 33, and the packing 38 is formed in a hollow disk shape with a synthetic rubber such as EPDM. The first valve body B1 is given buoyancy by the air accumulated in the float chamber 33 sealed from the outside. The first valve body 30 is opened so that a drainage passage 37 having a smaller diameter than the first valve seat 12 which is formed by integrally forming the inner surface of the float chamber 33 at the bottom of the resin tank A1 penetrates in the vertical direction. In addition, the first arm 35 on the side, the hook 31 for engaging the pull-up member D1, and the second valve seat 39 for seating the second valve body B2 on the upper outer periphery of the drainage passage 37. And the packing fitting part 32 provided with the hook for elastically deforming and fitting packing 38 like the 2nd valve main body 20 is integrally provided in the lower outer periphery of the drainage channel 37. A bearing recess 36 is formed in the end portion of the first arm 35 in a front inverted U shape from the lower end surface, and the hinge shaft 14 provided at the bottom of the resin tank A1 is sandwiched between the bearing recesses 36 so that the resin It is attached to the tank A1 so as to be swingable in the vertical direction. A hinge shaft 34 is provided above the end of the first arm 35 for mounting the second valve element B2 so as to be swingable in the vertical direction.
[0015]
The first valve body B1 has a plate-like flow pressure that interferes with the wash water passing through the drainage passage 37 at a position facing the first arm 35 provided in the drainage passage 37 and connected to the first valve body 30. Three pressure receiving members R are integrally formed. In addition, a cutting guide groove G having a V-shaped cross section serving as a guide for bending and cutting the fluid pressure receiving member R is formed in the connection portion between the substantially central portion in the longitudinal direction of the fluid pressure receiving member R and the drainage passage 37. . By providing the fluid pressure receiving member R at a position facing the first arm 35 provided continuously to the first valve body 30, the washing water passing through the drainage passage 37 of the first valve body B1 interferes with the resistance member R. It is possible to increase the moment for preventing the first valve element B1 from opening around the hinge shaft 14 generated in this manner. On the other hand, since the fluid pressure receiving member R can be bent and cut to match the characteristics of various toilets, the same toilet flush tank device can be used for various toilets. It is also possible to use the same first valve body B1. At this time, since the cutting guide groove G is provided in the fluid pressure receiving member R, it can be bent and cut by hand bending without using a special tool.
[0016]
Next, the operation of the toilet bowl cleaning tank device will be described. First, as shown in FIG. 1, the packing 28 of the second valve body B2 is in contact with the second valve seat 39, and the packing 38 of the first valve body B1 is in contact with the first valve seat 12, respectively. Since the packings 28 and 38 are elastically deformed by the dead weight of the valve bodies B1 and B2, the packing 28 and the second valve seat 39, the packing 38 and the first valve seat 12 are in close contact with each other in a watertight state, and the valve device B is surely secured. The valve is closed.
[0017]
When the valve opening means C shown in FIGS. 3 and 4 is rotated counterclockwise, for example, the second valve body B2 is pulled up via the pull-up member D2, and accordingly, as shown by the two-dot chain line in FIG. Only the second valve element B2 is opened and small cleaning is performed. Further, when the valve opening means C is rotated clockwise, for example, the first valve body B1 is pulled up via the pull-up member D1, and the second valve body B2 and the first valve body B1 are simultaneously opened as shown in FIG. Large washing is performed.
[0018]
As shown in FIG. 1, in the case of small washing, the head pressure applied to the second valve element B2 is reduced by the start of drainage, so that the operation of the valve opening means C is maintained and the second valve element B2 is not pulled up. Even so, the state in which the second valve body B2 is pulled up by the buoyancy of the float F attached via the lifting member D2 is maintained, and the drainage is continued.
[0019]
At this time, if the amount of washing water drained from the water storage tank is smaller than the amount of washing water flowing out of the bowl of the toilet bowl or the like, the drainage passage 37 of the first valve body B1 is smaller than the diameter of the first valve seat 12. The first valve body B1 is not opened by the buoyancy of the first valve body B1 because the differential diameter is small and the differential pressure of the area difference is applied to the first valve body B1. However, when the amount of the wash water drained from the water storage tank is larger than the amount of the wash water flowing out from the toilet bowl or the like, the upstream side and the downstream side of the first valve body B1 are instantaneously filled with water. Thus, the differential pressure of the washing water that was acting to close the first valve body B1 is released, and the first valve body B1 is likely to open due to the buoyancy of the first valve body B1, but the flow pressure The washing water passing through the drainage passage 37 hits the pressure receiving member R and the force that presses the first valve body B1 against the first valve seat 12 is not actuated to open the valve.
[0020]
When the washing water in the resin tank A1 reaches a predetermined water level due to drainage, the washing remaining in the resin tank A1 acting on the second valve body B2 and the second valve body B2 rather than the buoyancy of the float F. Since the head pressure of water and the negative pressure generated by the drainage of washing water increase, the second valve body B2 cannot be pulled up, the second valve body B2 descends and closes, and the drainage is stopped. The
[0021]
As shown in FIG. 2, in the case of large cleaning, since the water pressure is hardly applied to the second valve body B2 and the first valve body B1 by the start of drainage, even if the first valve body B1 is not pulled up, Since the second valve element B2 is maintained in a state where the second valve element B2 is pulled up by the buoyancy of the float F and the first valve element B1 is pulled up by the buoyancy of the float chamber 33, the drainage is continued.
[0022]
First, when the water level of the washing water in the resin tank A1 is lowered to the position of the float F by the drainage and protrudes from the water surface, the buoyancy applied to the second valve body B2 is lowered, so the second valve body B2 is pulled up. However, since the second valve element B2 is opened at 90 degrees or more, the valve opening state is maintained by the movement of the center of gravity of the second valve element B2 and the float F.
[0023]
Next, when the washing water in the resin tank A1 reaches a predetermined water level due to further drainage, the resin tank A1 acting on the first valve body B1 and the first valve body B1 rather than the buoyancy of the first valve body B1. Since the head pressure of the washing water remaining in the interior and the negative pressure generated by the drainage of the washing water become larger, the first valve body B1 cannot be pulled up, and the first valve body B1 descends. Close the valve. At this time, since the opening degree of the second valve body B2 becomes 90 degrees or less in conjunction with the closing of the second valve body B2, the second valve body B2 is also closed and drainage is stopped.
[0024]
In this embodiment, the fluid pressure receiving member R is integrally formed with the first valve body B1, but the present invention is not limited to this, and the first valve body B1 and the adhesive or screw are formed after being molded separately. It may be attached by.
[0025]
Further, the water storage tank A, the valve opening means C, the lifting members D1, D2, and the like are not limited to the structures and materials described in the embodiments, and may be other structures and materials. And although the water storage tank A was comprised by the double structure by the resin tank A1 and the ceramics cover A2, it is needless to say that it is not limited to this and may have a conventionally well-known single structure.
