[0004]

By the way, in the toilet apparatus, it is preferable that flush water is supplied to the toilet in a vigorous manner in order to discharge wastes in the toilet. That is, in the toilet device, it is preferable to increase the flow rate of the washing water discharged from the washing water tank device per unit time.

Therefore, conventionally, the flow rate of the washing water per unit time has been increased by increasing the opening area of the drain port. However, when increasing the opening area of the drain port 930a, a greater force is required when operating the operation handle 950. That is, as the opening area of the drain port 930a increases, the area of the valve 940 increases accordingly. And the valve 94
When the area of “0” increases, the amount of washing water stored in the upper portion of the valve 940 also increases, so that the force pressing the valve downward also increases. At this time, in order to open the valve 940, it is necessary to apply to the operation handle 950 a force that overcomes the force of the flush water stored above the valve 940 pushing the valve downward. As described above, when increasing the opening area of the drain port 930a, the operation handle 950 must be operated with a larger force.

[0034]

Next, embodiments of the present invention will be described based on examples.

A. First embodiment: A-1. Toilet device: FIG. 1 is a schematic sectional view of a toilet device to which the present invention is applied. This toilet device includes a flush water tank device 100 for storing flush water and a toilet 200.
A washing water guide 300 for guiding washing water from the washing water tank device 100 to the toilet 200 is provided below the washing water tank device 100.

A-2. Washing water tank device: FIG.
FIG. 2 is an explanatory diagram showing an enlarged view of the washing water tank device 100 of FIG. FIG. 2A is a cross-sectional view of the washing water tank device 100 when viewed from the same direction as that of FIG. 1, that is, the + x direction of FIG. 1, and FIG. 2B is viewed from the + y direction. 1 shows a sectional view of the cleaning water tank device 100 at the time.

The flush water tank device 100 discharges flush water stored inside and supplies flush water to the toilet 200 (FIG. 1). In the cleaning water tank device 100, the amount of cleaning water to be discharged can be changed between the time of large cleaning and the time of small cleaning.

The washing water tank device 100 includes a tank 130 for storing washing water and a drain port 13 provided at the bottom of the tank.
0a, a valve 140 for opening and closing the drain port 130a, and an operation handle device 150 provided on a side wall of the tank body 130.
And the L-shaped member 1 connected to the operation handle device 150
60, a chain 170 connecting the L-shaped member 160 and the valve 140, and a float 17 mounted in the middle of the chain 170.
And 2.

The washing water tank device 100 has a ball tap (not shown) as a water supply means above the tank 130. The ball tap has a well-known configuration, and includes a water supply valve connected to a water pipe and a tank 130.
And a float that opens and closes a water supply valve by moving up and down according to the water level in the inside. When the water level of the washing water in the tank 130 is lowered, the water supply valve is opened by lowering the float and the washing water is supplied. On the other hand, when the water level rises due to the supply of water into the tank 130, the water supply valve is closed by the rise of the float, and the inside of the tank 130 is maintained at a predetermined full water position.

The valve 140 is provided to be openable and closable about a shaft 141. When the valve 140 is closed, washing water is stored inside the tank 130, and when the valve 140 is open,
The cleaning water stored in the tank 130 is discharged. The valve 140 itself is configured to be closed when submerged. That is, the valve 140 has a larger specific gravity than water. Instead of using such a valve, or in addition to using such a valve, a weight may be attached to the valve, or a force may be applied in the closing direction by a spring.

The operation handle device 150 includes an operation handle 151 and an operation handle adjustment unit 152 for adjusting the operation of the operation handle.

The operation handle 151 is rotatable in the directions of arrows A and B. When the operation handle is turned in the direction of arrow A, the large cleaning process is executed, and when the operation handle is turned in the direction of arrow B, the small cleaning process is executed. Operation handle 151
The L-shaped member 1 via the operation handle adjustment unit 152
60 are connected. Therefore, the operation handle 15
When the L-shaped member 160 is rotated, the L-shaped member 160 is also rotated. As a result, the chain 17 attached to the tip of the L-shaped member 160 is rotated.
0 will raise the valve 140. By rotating the operation handle 151 in this manner, the valve 140 is opened.

The operation handle adjusting section 152 has a function of determining the discharge amount of the washing water at the time of large-scale washing.
That is, the operation handle adjustment unit 152 is configured to rotate the operation handle 151 and the L-shaped member 1 during the heavy cleaning.
When 60 returns to its original position, it generates a resistance force. This resistance is generated by a damper mechanism provided in the operation handle adjustment unit 152. As a result, the valve 140 connected to the L-shaped member 160 via the ball chain 170
Closes slowly while receiving upward resistance from the operation handle adjustment unit 152. As can be understood from this description, by adjusting the resistance of the operation handle adjustment unit 152,
Since the opening time of the valve 140 can be adjusted, the tank body 130
It is possible to adjust the discharge amount of the washing water discharged from the cleaning device. In addition, the operation handle adjustment unit 152 of the present embodiment includes:
At the time of small cleaning, since no resistance is generated, the operation handle 151 and the L-shaped member 160 immediately return to their original positions.

When the water level is full, the float 172 is provided with the valve 140.
Floating in the submerged state while maintaining the closed state. That is, the float 172 gives the valve 140 a buoyancy (force in the valve opening direction) smaller than the force in the valve closing direction in the submerged state.

The attachment position of the float 172 to the chain 170 is as follows.
Determine the discharge amount of washing water during small cleaning. That is, when the float 172 is exposed to the water surface by the drainage of the washing water, the buoyancy is rapidly reduced, and the float 172 loses the force in the valve opening direction. At this time, the opening degree of the valve 140 is reduced, and the valve 140 is closed by the drawing force at the time of drainage. Thus, at the time of small cleaning, the valve 140
After the washing water is discharged until the float 172 is exposed, the float 172 is closed. From this, if the attachment position of the float 172 to the chain 170 is changed, the discharge amount of the washing water at the time of the small washing can be adjusted.

As can be understood from the above description, when the operation handle 151 is rotated in the direction of arrow A or the direction of arrow B from the initial state shown in FIG. 2, one end of the valve 140 is pulled up by the L-shaped member 160. The valve 140 is connected to the shaft 14
1 and the drain port 130a is opened. Thus, the washing water stored in the tank main body 130 flows out from the drain port 130a. The washing water tank device 100 is described in further detail in, for example, JP-A-10-219785 disclosed by the present applicant.

A-3. Toilet: FIG. 3 shows the toilet 200 of FIG.
It is explanatory drawing which expands and shows. FIG. 4 is an explanatory diagram showing the toilet 200 when viewed from the + z direction in FIG. In addition,
FIG. 3 is a cross-sectional view taken along the line S-S 'of FIG.

The toilet 200 has a ball portion 20 for receiving dirt, a cleaning water supply portion for supplying cleaning water to the ball portion 20, and a cleaning water for discharging cleaning water together with dirt from inside the ball portion 20. And a discharge unit.

The ball portion 20 has a water-covered surface 23 that is in contact with the stored water RW even when the toilet 200 is not washed, and a drying surface 24 that is not in contact with the stored water RW when the toilet 200 is not washed.

The washing water supply section includes a washing water supply passage 41, a jet water supply passage 46 (see FIG. 4) connected to the washing water supply passage 41, and a rim water supply passage 43.

The washing water supply channel 41 is provided behind the ball section 20. The washing water supply channel 41 has a washing water supply hole 40 at a connection portion with the washing water tank device 100. The washing water discharged from the washing water tank device 100 is
The washing water is supplied to the washing water supply passage 41 through the washing water supply hole 40. The washing water supply channel 41 has a branch hole 42 on the upper wall in the middle thereof, which is a connection hole with a rim water supply channel 43 (described later). Further, the washing water supply channel 41 is provided on the downstream side of the branch hole 42 with a stagnant portion 4 having a shape extending obliquely downward.
1a.

The jet water supply channel 46 is formed so as to curve the inside of the toilet as shown in FIG. The Z water supply channel 46 connects between the Z water supply hole 45 provided on the side wall of the retaining portion 41a and the Z jet outlet 22.

The rim water supply channel 43 is provided inside the rim portion 21 provided above the ball portion 20, as shown in FIGS. The rim water supply channel 43 is a hollow portion formed into a cylindrical shape in a range along the inner periphery of the upper end of the ball portion 20. The washing water flowing into the branch hole 42 is supplied to the rim water supply passage 4.
3 is distributed. On the back side of the rim portion 21, 5
Water drainage holes 44 a to 44 e are provided, and each of the holes 44 a to 44 e is connected to the rim water supply passage 43.

The washing water discharge portion includes a concave portion 26 provided below the ball portion 20, a connection path 31, an ascending path 32, and a descending path 3.
3 and a drainage channel composed of:

The concave portion 26 has a function as a waste pool. An outlet 25 is formed at the back of the recess 26.
The recess 26 is connected to the drainage channels 31 to 33 at the outlet 25.

The drain passages 31 to 33 are flow passages for discharging washing water and dirt from the ball portion 20. The drainage channel includes a connection path 31 extending diagonally upward from the discharge port 25, a rising path 32 extending diagonally upward continuously with the connection path 31,
It comprises a rising path 32 and a descending path 33 which extends downward continuously. As shown in FIG. 3, the descending path 33 extends substantially vertically downward after passing over the weir 34 which is the highest position below the inner wall of the ascending path 32. For this reason,
The drainage channel near the weir 34 forms a bent portion. The descending path 33 is connected to a drainage riser pipe 90 via a drainage socket 70.

The water level of the pool water RW in the ball portion 20 at the time of non-cleaning is maintained at the normal water level line WL which is the same as the height of the weir 34 of the drainage channel. The pooled water RW can prevent the backflow of odor from the drainage mechanism to the ball portion 20 and the entry of insects and the like.

Next, the washing operation by the washing water supply unit and the washing water discharge unit will be described. Free fall from a high water level in the washing water tank device 100 (FIG. 1)
The cleaning water supplied to the cleaning water supply hole 40 via the cleaning water guide 300 is guided by the cleaning water supply passage 41 at an obliquely downward inclination and flows into the retaining portion 41a. With this inflow,
The water level in the stagnant portion 41a rises higher than the water level in the ball portion 20, and accordingly, the accumulated water in the lower portion of the stagnant portion 41a and in the jet water supply passage 46 (hereinafter, referred to as "jet water"). ) Flows toward the jetting hole 22 in the ball portion 20. As a result, the jet water from the jet port 22 and the washing water flowing into the retaining portion 41a are jetted sequentially.

The washing water from the jet outlet 22 is jetted toward the outlet 25. Therefore, the accumulated water RW in the connection path 31 and the ascending path 32 and the dirt accumulated in the recess 26 are pushed up in the direction of the weir 34. As a result, the water level in the rising path 32 rises rapidly beyond the normal water level line WL, and the connection path 31, the rising path 32, and the bent portion immediately become full. At this time, a pressure difference is generated between the front end surface of the water filled in the bent portion and the water surface of the stored water RW in the ball portion 20. Due to this pressure difference, a downward pulling force is generated. Such an action is called a siphon action. By this siphon action, the dirt in the ball portion 20 is drawn in the direction of the weir 34 together with the stored water RW and the washing water.

The washing water supplied from the washing water tank device 100 gradually accumulates in the stagnant portion 41a, and the washing water supply passage 4
The water level in 1 rises. The water level in the washing water supply channel 41 is
When the cleaning water rises to the height of the branch hole 42,
Flows into. The washing water that has flowed into the branch hole 42 is supplied to the rim water supply passage 43 and is discharged from the water discharge holes 44 a to 44 e connected to the rim water supply passage 43.

As shown in FIG. 4, a rim water supply channel 43 is formed by a long hole 44d formed near the branch hole 42 behind the toilet 200 and a long hole 44e formed in front of the toilet 200. A large amount of the washing water flowing around is discharged vigorously. The cleaning water discharged from the long holes 44d and 44e becomes the mainstream, and the clockwise turning force is applied to the cleaning water discharged from the water discharging holes 44a to 44e. The washing water to which the swirling force has been applied flows down along the surface of the drying surface 24 of the toilet 200, and the accumulated water RW in the ball portion 20.
To join. By this confluence, the swirling force of the cleaning water is transmitted to the stored water RW in the ball portion 20. As a result, a clockwise swirling flow is generated in the ball portion 20. The dirt in the ball portion 20 is caught in the swirling flow and collected in the concave portion 26 and goes to the discharge port 25.

The accumulated water RW in the ball portion 20 which has been increased by the discharge from the water discharge holes 44a to 44e is drawn into the drainage channel by the siphon effect already generated. The sewage and sewage are descended with strong force by siphon action.
3 and is discharged from the drainage riser pipe 90 through the drainage socket 70.

When the continuation of the siphon action is over, the inside of the ball portion 20 and the inside of the drainage channel are supplied from the draining holes 44a to 44e and the jetting hole 22 instead of the pool water RW accumulated before the start of washing. Part of the washing water is accumulated in the toilet 200 as new accumulated water RW.

When the supply of the washing water from the washing water tank device 100 is completed, the water level in the washing water supply passage 41 which has been full is gradually lowered, and the discharge of the washing water from the drain holes 44a to 44e and The jetting of the washing water from the jet jet holes 22 is sequentially stopped. Thereafter, the level of the stored water RW becomes the height of the normal water level line WL, as before the start of cleaning. Thus, the cleaning of the toilet 200 is completed.

A-4. Cleaning water guide: As mentioned above,
Wash water from the wash water tank device 100 is supplied to the toilet 200 via the wash water guide 300. FIG.
FIG. 5 is an explanatory diagram showing a cleaning water guide 300 in an enlarged manner. The washing water guide 300 includes an inlet 301 for flowing the washing water discharged from the drain port 130a of the washing water tank device 100, an outlet 302 for flowing the washing water, and an outlet for the washing water from the inlet 301. And a side wall 303 that forms a flow path for leading to the channel 302. The inflow port 301 and the outflow port 302 have a substantially circular shape, and the cross section of the flow path through which the washing water flows is also formed in a substantially circular shape by the side wall 303. The cross-sectional area S2 of the outlet 302 is
1 is set larger than the cross-sectional area S1. Further, the cross-sectional area of the flow path gradually increases from the inlet 301 to the outlet 302.

As can be seen from the connection state in FIG. 1, the cross-sectional area S1 of the inflow port 301 of the washing water guide 300
Is set to substantially the same size as the cross-sectional area of the drain port 130a of the washing water tank device 100.

When the washing water is discharged from the washing water tank device 100 by using the washing water guide 300, compared with the case where the washing water guide 300 is not used, the cleaning water per unit time discharged from the washing water tank device 100 is used. The amount of washing water can be increased. This is because the cross-sectional area S2 of the outlet 302 of the washing water guide 300 is
Area of the drainage port 130a (the cross-sectional area S of the inflow port 301)
(Approximately equal to 1). If such a washing water guide 300 is applied to the toilet apparatus (FIG. 1), the flow velocity near the outlet 302 does not become too small, so that the unit time depends on the size of the cross-sectional area S2 of the outlet 302. Per flow can be increased. As a result, the flush water tank device 100
Since more washing water is supplied per unit time in FIG. 3, it becomes possible to flush the dirt accumulated in the ball portion 20 vigorously.

The rate of increase of the diameter R of the flow path of the cleaning water guide 300 shown in FIG.
, The flow path of the cleaning water guide 300 has a frusto-conical shape expanding toward the end,
The increase rate of the diameter R may be constant. When the increasing rate of the diameter R is constant, the flow path of the cleaning water guide has a substantially truncated cone shape. In general, the cross-sectional area of the flow path of the cleaning water guide may be monotonically increased from the inlet to the outlet.

FIG. 6 is an explanatory diagram showing the positional relationship between the washing water guide 300 and the washing water tank device 100. FIG.
