DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush water tank device for a toilet bowl, which can be set to have different amounts of flush water for so-called large cleaning and small cleaning.

[0002]

2. Description of the Related Art Conventionally, a flush water tank device for a toilet bowl of this type has a function of changing a drainage amount of flush water in large cleaning and small cleaning. It is known that the amount of drainage is reduced as compared with washing for use to achieve a water saving effect (Japanese Utility Model Laid-Open No. 2-39842). FIG. 15 is a schematic sectional view showing a conventional flush water tank device 200 for a toilet. In FIG. 15, a toilet flush water tank device 200 includes a tank body 204 having a drain port 202 at a lower portion, and a float valve 2 for opening and closing the drain port 202.
06, an operation handle 208 protruding from the outer wall surface of the tank main body 204 and capable of rotating operation, a chain 210 connecting the operation handle 208 and the float valve 206, and a rotation of the shaft member 208a of the operation handle 208 when returning. And a damper means 212 for controlling the speed. Operation handle 2
08 can be set to different operation amounts for large cleaning and small cleaning, and this is reflected in the opening of the float valve 206.

As described above, by changing the opening of the float valve 206 in accordance with the operation amount of the operation handle 208,
The time until the damper means 212 closes the float valve 206 is adjusted to set a different drainage amount.

[0004]

However, the flush water tank device 200 for a toilet bowl has a hemispherical float valve 206.
Is used, once the float valve 206 is opened, it is opened to the highest position by the air in the float valve 206, and the opening degree of the float valve 206 is changed according to the operation amount of the operation handle 208. It is difficult to set a predetermined opening. In other words, once the float valve 206 is opened, the buoyancy of the float valve 206 tends to increase the opening degree of the float valve 206, so that the amount of water becomes larger than a target amount of water in the small cleaning. Will not do it.

An object of the present invention is to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a flush water tank device for a toilet bowl, which can surely flow a predetermined amount of water even during small cleaning. I do.

[0006]

Means for Solving the Problems and Action / Effect The first invention for solving the above-mentioned problems is a toilet flushing system in which the drainage amount of washing water can be set to a first water amount and a second water amount. In the water tank device, a tank body, a drain port formed in a lower portion of the tank body, and a port provided to open and close the drain port, and a force in a valve closing direction due to its own weight or urging force even in a submerged state. And a connecting member provided at a position operable from the outside of the tank body and connected to one end of the valve member, and an operation of opening the valve member via the connecting member. And a second opening corresponding to a first opening corresponding to the first amount of water or a second opening smaller than the first amount of water by operating the operating unit. A water flow control unit that can be operated to open the valve Adjusting the time until the valve member closes by urging a force against the force in the valve closing direction of the valve member according to the operating means having the first opening degree or the second opening degree. And a valve closing adjusting means for adjusting the first water amount or the second water amount.

In the flush water tank device for a toilet according to the present invention, when the operating portion of the operating means is operated so that the valve opening of the valve member corresponds to the first water amount or the second water amount, the valve member is connected via the connecting member. Opens the drain port at the first opening degree or the second opening degree, and the washing water of the tank body is discharged through the drain port.

Since the valve member has a force in the valve closing direction due to its own weight or urging force even in a submerged state, the valve member immediately performs a closing operation.
It is determined by the balance with the force urged in the valve opening direction against the valve member by the valve closing adjusting means. The valve member opened at the first opening degree or the second opening degree closes when the washing water flows by the first water amount or the second water amount. As described above, the drainage amount of the cleaning water is determined by only the valve opening amount of the valve member regardless of the water level of the cleaning water. Therefore, the cleaning water can be discharged with a stable water amount.

Here, as a preferable mode of the valve closing adjusting means, a resistance force applied to the valve member can be realized by a damper portion by viscous resistance or frictional resistance of the fluid.

In a preferred aspect of the operating means, the operating portion is constituted by an operating handle which is reciprocated and rotated, and the water amount adjusting portion is adapted to determine the operating amount of the operating handle from an initial position.

Further, when a damper portion is used for the valve closing adjusting means, it is preferable to provide a clutch means between the operating handle. That is, the clutch means does not transmit the rotational force to the damper portion when the operation handle is operated in the direction in which the valve member opens, and applies a resistance force when the valve member closes. By providing such a clutch means, the damper portion does not generate resistance when the valve is opened, so that the operation handle can be operated smoothly, and the durability of the damper portion itself can be improved. it can.

[0012] The valve closing adjusting means may be provided on the valve member in addition to being configured to generate a resistance force in conjunction with the operating means. That is, the valve member may be rotatably supported about the shaft, and the damper may be connected to the shaft to apply a resistance force in the valve closing direction.

When an operation handle is used for the operation section, an operation amount changing means which can change the range of the operation rotation amount of the operation handle is applied. By changing the operation rotation amount, the first water amount or the second water amount can be changed. The amount of water can be adjusted,
Various tank body capacities can be accommodated.

Further, as means for applying a force in the valve closing direction to the valve member, means for increasing the specific gravity of the valve member itself than water, or means for increasing the specific gravity than water by attaching a weight, Even if the member itself has a specific gravity lower than that of water, it can be realized by mounting a spring that constantly urges the force in the valve closing direction.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the present invention will be described below.

FIG. 1 is a sectional view showing a flush water tank device 20 for a toilet according to an embodiment of the present invention. In FIG. 1, the toilet flush water tank device 20 can change the amount of flush water to a first water amount (large wash) and a second water amount (small wash), and has a drain port 30a at a lower portion. A tank body 30, a ball tap (not shown) as a water supply means provided on the upper part of the tank body 30, and a drain port 30 a

The ball tap has a well-known structure, that is, it has a water supply valve connected to a water pipe, and a float that moves up and down according to the water level of the tank body 30 to open and close the water supply valve, When the water level of the washing water in the tank body 30 decreases, the float lowers to open the water supply valve. On the other hand, when the water level in the tank body 30 increases, the float raises the water supply valve. It closes, thereby maintaining the inside of the tank body 30 at a predetermined full water position.

The valve device 40 includes a drain pipe 41 and a valve member 42 for opening and closing the drain port 30a of the drain pipe 41.
And a damper device 4 for controlling the opening / closing speed of the valve member 42.
3 is provided. The drain pipe section 41 is connected to the tank body 3.
A drain pipe main body 41a is screwed and fixed to a tank bottom hole 33a formed in the tank bottom 33 of the No. 0. The drain pipe main body 41a has a drain port 30a at the upper end thereof and protrudes from the bottom surface of the tank main body 30.
The lower end is connected to a ball portion of a Western-style toilet bowl (not shown). An overflow pipe 35 is connected to a side of the drain pipe section 41. This overflow pipe 35 is
The tank is erected up to the upper part of the tank body 30 so that washing water can be introduced from the opening at the upper part. When the water level in the tank body 30 exceeds the full water level due to a failure such as a ball tap, the drain pipe section Drain from 41 to the bowl side of the Western style toilet. This prevents the washing water from flowing out from the upper part of the tank body 30 and damaging the floor of the toilet room.

2 to 4 show the vicinity of the valve device 40, FIG. 2 is a rear view, FIG. 3 is a front view thereof, and FIG. 4 is a plan view thereof. In these figures, the valve device 40 includes a valve member 42 supported at the lower end of the overflow pipe 35 so as to be openable and closable. The valve member 42 includes a disc-shaped valve body 42a for opening and closing the drain port 30a, and a valve body 42a.
The valve support portions 42b and 42c are bifurcated so as to straddle the overflow pipe 35 from both sides of the valve support section 42a.
Is supported so as to be rotatable.

The valve member 42 has a higher specific gravity than water.
In addition, it is formed to have a specific gravity that is closed by its own weight even when it is submerged.

The upper portion of the valve support portion 42b shown in FIG. 3 is formed in a disc shape, and the outer periphery of the upper portion is provided with a damper device 4b.
3 is formed. The damper device 43 includes a connecting gear 43a meshed with the valve-side tooth body 42d and freely supported by the shaft in the overflow pipe 35.
And a damper part 43b connected to the shaft of the connecting gear 43a.
And The damper portion 43b fills the inside with a viscous resistance material and receives the viscous resistance of the viscous resistance material to apply a rotational resistance to the shaft.

With the structure of the valve device 40, when one end of the valve member 42 is pulled up through the ball chain 60 by operating the operation handle device 50 shown in FIG.
Rotates about a shaft at the valve support portions 42b and 42c. At this time, the valve-side tooth body 4 is provided above the valve support portion 42b.
2d is formed, and the valve-side tooth body 42d rotates the connecting gear 43a and further rotates the damper portion 43b. Therefore, the valve member 42 opens while receiving the turning resistance when the valve is opened.

On the other hand, when the valve member 42 is in the open state, the valve member 42 rotates in the valve closing direction by its own weight even in the submerged state. At this time, similarly to the valve opening operation, a rotational resistance is received from the damper portion 43b via the valve-side teeth 42d of the valve support portion 42b and the connecting gear 43a. Therefore, when the valve member 42 is closed, the valve closing speed is determined by the balance between the force in the valve closing direction of the valve member 42 and the rotational resistance force of the damper portion 43b, that is, the time until the valve is closed is determined. .

Next, the tank side wall 31 of the tank body 30
Will be described. FIG.
3 is a sectional view showing the operation handle device 50. FIG. In FIG. 5, the operation handle device 50 is attached to the tank side wall 31, and includes a sleeve 51 and an operation handle 55.
And The sleeve 51 includes a sleeve main body 51a having a fitting hole 51c, and a flange portion 51b at one end of the sleeve main body 51a. The sleeve main body 51a is inserted into a mounting hole 31a formed in the tank side wall portion 31. At the same time, it is fixed to the tank side wall 31 by being fixed with a nut 53 at a screw portion 51d on the outer peripheral portion of the sleeve main body 51a.

The operating handle 5 is provided on the sleeve 51.
5 is rotatably supported. The operation handle 55 is
Handle body portion 55a having handle operation portion 55b
A shaft portion 55c fixed to the handle body 55a and rotatably supported by the fitting hole 51c;
Spindle 55 fixed to the tip of shaft 55c
d, and the upper end of the chain 60 is fixed to the tip of the spindle 55d. Further, a rotation range restricting portion 56 is formed over the flange portion 51b of the sleeve 51 and the handle main body portion 55a. FIG. 6 is a sectional view taken along the line 6-6 in FIG. 6, the rotation range restricting portion 56 includes a restricting protrusion 57 protruding from a lower portion of the handle main body portion 55a and a stopper portion 58 protruding from the flange portion 51b. The stopper portion 58 is a semi-cylindrical projection, one end of which is a large-use regulating end 58a, and the other end of which is a small-use regulating end 58b.
Since the regulating protrusion 57 is located on the lower side in the vertical direction due to the gravity of the handle operation portion 55b, the large operating angle θ1 is between the regulating protrusion 57 and the large regulating end 58a, and the small operating angle θ1 is small between the small regulating end 58b. Operating angle θ2.

In the operation handle device 50, in order to perform heavy cleaning, a large cleaning position P where the regulating protrusion 57 abuts the large regulating end 58a with the handle operation portion 55b.
1 (large operation angle θ1). Thereby, the handle body 55a, the shaft 55c, and the spindle 5
5d rotates integrally, and pulls up the ball chain 60 fixed to the tip of the spindle portion 55d, whereby the valve member 42 opens. On the other hand, in order to perform small cleaning, the handle operation unit 55b
As a result, the regulation protrusion 57 rotates to the small washing position P2 (small operation angle θ2) where the regulation projection 57 contacts the small regulation end 58b. As a result, the ball chain 60 is pulled up by the spindle portion 55d in the same manner as in the large cleaning, whereby the valve member 42 is opened.
However, in the case of the small cleaning, since the small operation angle θ2 is smaller than the large operation angle θ1, the amount by which the valve member 42 is pulled up is small, and the valve opening amount is also small.

Next, a series of drainage operations of the toilet flush water tank device 20 will be described. Now, from the state of FIG. 1 in which the valve member 42 is closed, the handle operation portion 55b of the operation handle device 50 is moved to the large cleaning position P in order to perform large cleaning.
When the valve member 42 rotates to 1, the valve member 42 rotates around the shaft and opens the drain port 30a. At this time, the handle operation unit 55
When b is released, the handle operation portion 55b returns to its original position by its own weight, and releases the force for lifting the valve member 42.
By opening the valve member 42, the washing water of the tank body 30 is sent into the bowl portion of the toilet through the drain port 30a,
The water level begins to drop.

The valve member 42 is gradually closed, but since its specific gravity is greater than that of water, even if the valve member 42 is submerged, its valve closing speed is limited by its own weight of the valve member 42 and the damper device. The speed is determined in balance with the resistance of the damper portion 43b. Then, when the valve member 42 is closed, almost the full amount of water in the tank body 30 is discharged.

That is, the damper device 43 includes the valve member 42
Within the time from the fully opened state to the time when the drain port 30a is closed, a resistance force is applied to the valve member 42 so that the washing water in the tank main body 30 can be almost completely drained. Therefore, if the operation handle 55 is turned to the large cleaning position P1, the tank body 3
The washing water in the water is discharged from the bottom of the tank body 30 to the drain port 30a.
Is discharged to the remaining height H1 (FIG. 1).

On the other hand, when the operation handle 55 is rotated to the small cleaning position P2 (counterclockwise) to perform the small cleaning, the valve member 42 is opened, and the cleaning water is discharged from the drain port 30a. Also in this case, when the hand is released from the operation handle 55, the operation handle 55 returns to the original position, and thereafter, the valve member 42 receives no force from the operation handle 55 side. However, since the small operation angle θ2 of the small cleaning position P2 of the operation handle 55 is smaller than the large operation angle θ1 of the large cleaning position P1, the opening degree of the valve member 42 is also small. Since the time until the valve member 42 closes is proportional to the initial opening degree of the valve member 42, the valve member 42 is independent of the water level of the tank body 30,
The tank body 30 is closed before all the washing water is discharged. For example, the height H2 from the bottom of the tank body 30
It is discharged to the remaining amount of (H2 <H1). Therefore, when the operation handle 55 is operated to the small cleaning position P2, a smaller amount of water is drained than in the large cleaning position P1.

As described above, according to the toilet water tank device 20 of the embodiment, the time during which the valve member 42 is open is determined by the operation amount of the operation handle 55, and the cleaning water added to the valve member 42 and the like. Since it is not affected by buoyancy, it is possible to stably discharge a constant amount of water even in small cleaning. Therefore, it is possible to reliably discharge an appropriate amount of water without excessively increasing the amount of cleaning water even during small cleaning as described in the related art.

In the above embodiment, the valve member 42
Is formed of a material having a higher specific gravity than water. However, the present invention is not limited to this. Any structure may be used as long as it generates a force in the valve closing direction in a submerged state. For example, as shown in FIG. The weight 45 may be attached to the valve member 42 to increase the substantial weight of the valve member 42, or a spring for urging the shaft of the valve member 42 to apply a force in the valve closing direction may be provided.

FIG. 8 shows a valve device 40 according to another embodiment.
B is a front view, and FIG. 9 is a plan view of a main part of the valve device 40B. 8 and 9, the valve device 40B includes a valve member 42B and valve support portions 42Bb (one is shown in the drawings) formed on both side ends of the valve member 42B. A valve-side tooth body 42Bd is formed on one of the valve support portions 42Bb. This valve side tooth body 42Bd is
B is engaged. The clutch gear 47B is connected to a connecting gear 46B via a shaft, and the connecting gear 46B is further connected to a damper section 43 via a damper gear 48B.
Bb.

The clutch gear 47B is provided with a valve-side tooth body 42.
When a rotational force in the counterclockwise direction a is received from Bd, that is, when a rotational force in the valve closing direction of the valve member 42B is received, the shaft is rotated to transmit the rotational force to the coupling gear 46B, while the valve-side teeth are rotated. When a rotational force in the clockwise direction b is received from the body 42Bd, that is, when a rotational force in the valve opening direction of the valve member 42B is received, the shaft body is not rotated and the connecting gear 46B is not rotated.

FIG. 10 is a configuration diagram showing the clutch gear 47B. In FIG. 10, a clutch gear 47B has an outer peripheral ring 47Bc having an outer peripheral tooth 47Ba engaged with the valve-side tooth 42Bd and having an inner peripheral tooth 47Bb on the inner peripheral side.
And a boss 47Bd connected to the shaft of the connecting gear 46B.
Rotating support 47Be having three planetary gears 47B
f. The rotation support member 47Be includes support portions 47Bg for rotatably holding the planetary gears 47Bf at intervals of 120 °, one end of the support portion 47Bg being a smooth curved portion 47Bh and the other end being a steep portion 4B.
7Bi. The clutch gear 47 having this configuration
When B receives a rotational force in the clockwise direction b through the outer peripheral teeth 47Ba, the planetary gear 47Bf slides on the curved portion 47Bh of the rotary support 47Be and can rotate on its own, so that the outer peripheral ring 47Bc is attached to the rotary support 47Be. Rotate against. On the other hand, when the clutch gear 47B receives a rotational force in the counterclockwise direction a via the outer peripheral teeth 47Ba, the planetary gear 47Bf is prevented from rotating by the steep portion 47Bi of the rotary support 47Be, and the outer peripheral ring 47Bc The gear 47Bf and the rotary support 47Be are integrated. Therefore, the clutch gear 47B rotates the outer circumferential ring 47
Bc idles and becomes uncoupled with the coupling gear 46B,
The rotation in the counterclockwise direction a establishes a connection state with the connection gear 46B.

In the valve device 40B according to the present embodiment,
When the valve member 42B is closed, similarly to the above-described embodiment, the valve member 42B functions to close at a constant valve closing speed by receiving the resistance force of the damper portion 43Bb.
When the valve opens, the clutch gear 47B moves to the damper portion 43B.
Since b is separated from the valve member 42B, there is no resistance when the valve member 42B is opened. Therefore, the operation handle can be operated smoothly without resistance when operating, and the load on the damper portion 43Bb when the valve member 42B is opened can be reduced, and the durability can be improved.

FIG. 11 is a schematic view showing an operation handle device 50C according to another embodiment. The operation handle device 50C according to the present embodiment has a configuration in which the large operation angle θ1 and the small operation angle θ2 can be changed. That is, the operation handle 55C is attached to the shaft 51
This case 5 is rotatably supported via Ca.
A stopper 58 is formed on 1C and the shaft 51Ca. The stopper portion 58 includes an arc-shaped rotating plate 57C fixed to the shaft, and a large adjustment screw 59a and a small adjustment screw 59b screwed to the lower end of the case 51C. The arc-shaped rotating plate 57C has one end serving as a large-use regulating end 57Ca and the other end serving as a small-use regulating end 57Cb.
and the angle formed by the tip of the large adjustment screw 59a becomes the large operation angle θ1, and the angle formed by the small regulation end 57Cb and the tip of the small adjustment screw 59b becomes the small operation angle θ2. The operation angle θ1 is larger than the small operation angle θ2. Therefore, the operation handle 55C rotates more in the case of large cleaning than in the case of small cleaning, and raises the valve member, so that the drainage amount can be set large.

The large adjustment screw 59a and the small adjustment screw 59b can be moved up and down to change the large operation angle θ1 and the small operation angle θ2, respectively. The amount of drainage that accompanies a change in the degree of opening of the member can be adjusted.

FIG. 12 is a sectional view showing a flush water tank device 70 for a toilet according to another embodiment. 12, a flush water tank device 70 for a toilet has a valve device 72 at a lower portion of a tank body 71 having a drain port 71a, and an operation handle device 80 for opening and closing a valve member 73 of the valve device 72.
It has. Although the valve device is provided with the damper function in the above embodiment, the present embodiment is different in that the operation handle device 80 has the damper function. That is, the valve device 72 is provided at the drain port 71 a at the lower part of the tank body 71. The valve device 72 includes a valve member 73 that opens and closes rotatably about a shaft 73a. The valve member 73 is configured to be closed even in a submerged state, that is, as described in the above-described embodiment, by itself or by attaching a weight, the valve member 73 is made heavier than water or a spring. The valve is configured to be closed by applying an urging force in the valve closing direction.

The operating handle device 80 is configured to have a damper function, and is configured to adjust the valve closing speed of the valve member 73 of the valve device 72. FIG.
3 is a sectional view showing the operation handle device 80. FIG.
In the operation handle device 80, the tank side wall 71
b, a handle operation section 81a and a spindle section 81 fixed to the handle operation section 81a.
b, and a damper device 82. The spindle portion 81b is connected to the valve member 73 through a ball chain 74 at the tip end. The operation handle 81 is rotatably supported by a case body 83 fixed to the tank side wall 71b. That is,
The case main body 83 is fixed to a mounting hole 71c of the tank side wall 71b by a case supporting portion 83b having a sleeve 83a, and is rotatably fitted by a spindle portion 81b through a fitting insertion hole 83d of the sleeve 83a. 81 is rotatably supported.

The damper device 82 is provided in a case body 83, and includes a handle-side gear 82a fixed to a spindle portion 81b and a handle-side gear 82a.
a, a connecting gear 82b constantly meshing with
And a damper portion 82c connected to the shaft body. As described above, the damper portion 82c urges the rotation resistance by the viscous resistance material, and the handle operation portion 81a, the spindle portion 81b, and the handle-side gear are provided even if the operation handle 81 rotates in any direction. 82a, connecting gear 82b
, A rotation resistance force is applied to the operation handle 81. The operation handle device 80 is provided with a rotation range restricting portion similar to that shown in FIG. 6. The cleaning position and the small-use cleaning position are configured to have different rotation angles.

In the toilet flushing water tank device 70 having such a configuration, when the operation handle 81 is operated to the large cleaning position with the tank body 71 being full of water, the operation handle 81 reduces the rotation resistance of the damper portion 82c. The valve member 73 rotates through the spindle portion 81b and the ball chain 74 while receiving.
Is opened, and the washing water is discharged from the drain port 71a. When the operating handle 81 is released, the valve member 73 receives a force in the valve closing direction even in a submerged state. Therefore, this force is applied to the ball chain 74, the spindle portion 81b, and the handle-side gear 82.
a, transmitted to the damper part 82c via the connecting gear 82b. For this reason, the valve member 73 receives the turning resistance of the damper portion 82c and closes while the valve closing speed is regulated. Then, the valve member 73 closes when the washing water in the tank main body 71 is almost discharged. On the other hand, the operation handle 81
Is operated to the small cleaning position, the valve member 73 is opened similarly to the large cleaning. However, since the rotation angle of the small cleaning position is smaller than that of the large cleaning position, the opening of the valve member 73 is small. For this reason, the time until the valve member 73 closes is shorter than that in the heavy cleaning, and the drainage amount of the cleaning water is small.

According to the flush water tank device 70 for the toilet according to the present embodiment, the rotation angle of the operation handle 81 is different between large cleaning and small cleaning, and such a difference in the operation amount causes the valve member 73 to change. The drainage amount of the washing water can be set to different values by changing the opening degree of the cleaning water. At this time, the valve member 73
Since a force is generated in the valve closing direction even in a submerged state, a stable drainage amount can be set even for small cleaning without causing a difference in drainage amount depending on the presence or absence of buoyancy.

The operation handle device 80 shown in FIG.
In addition, a rotation range restricting portion 85B as shown in FIG. 14 may be provided to add a function of changing the amount of cleaning water for large cleaning and small cleaning. FIG. 14 shows the operation handle device 80.
It is sectional drawing which shows B. In FIG. 14, the operation handle device 80B includes a spindle portion 8 of the operation handle 81B.
1Bb, a handle-side gear 82Ba is provided, and the handle-side gear 82Ba is connected to the connecting gear 82B.
b, it is connected to the damper portion 82Bc. Also,
A rotation range restricting portion 85B is provided on the upper portion of the handle-side gear 82Ba and on both sides thereof. The turning range restricting portion 85B includes an arc-shaped turning plate 86 formed integrally with the handle-side gear 82Ba, a large adjusting screw 87a attached to the projecting portions 83Ba, 83Bb on both sides of the case main body 83B, and a small adjusting screw 87a. An adjustment screw 87b is provided.

With this configuration, the operation handle 81B
When the spindle portion 81Bb is rotated by rotating the damper portion 82B via the handle-side gear 82Ba and the connecting gear 82Bb in either case of large cleaning or small cleaning.
c. In addition, since the rotation of the spindle portion 81Bb also rotates the arc-shaped rotation plate 86 integrally,
