2. Description of the Related Art A toilet bowl cleaning device is widely used which is provided with a handle device for rotating the pulling shaft, and the valve body opens the valve to discharge the cleaning water inside the tank to clean the toilet bowl.

FIG. 4 shows an example thereof. The cleaning device in the illustrated example has a valve body for cleaning the toilet bowl for stools and a valve body for cleaning the toilet bowl for urine independently, and discharges the cleaning water at different amounts by opening each valve body. In the figure, reference numeral 200 is a tank for storing flush water for the toilet bowl inside.

Inside the tank 200, a valve seat 202 integral with an overflow pipe 206 is provided around a discharge port 204, and the discharge port 204 is opened and closed by seating or separating a valve body 208 on the valve seat 202. It has become so. Here, the valve element 208 is a valve element for cleaning a toilet bowl in case of stool.

The valve body 208 is provided with an opening, and the opening is opened and closed by a second valve body 210 for cleaning the toilet bowl during urination. Floats 212 and 214 are attached to the pair of valve bodies 208 and 210 directly or via a chain 226A.

At the upper part of the tank 200, a pulling shaft 214
A handle device 218 having a handle 216 for rotating the handle and a handle 216 is provided. Thus, the pulling shaft 214 is provided with a pair of levers 220 and 222, one lever 220 of which is connected to the float 212 via a chain 224, and the other lever 222 of which is floating via a chain 226. Each is connected to 214.

In the toilet bowl cleaning device shown in FIG. 4, when the handle 216 is rotated from the neutral position (original position) in one direction (to the positive side), the lever 220 is also rotated and the valve body 208 is chained. Lifted via 224 and float 212.

As a result, the outlet 204 is opened, and the flush water for the toilet in the tank 200 is discharged from the outlet 204 toward the toilet to wash the toilet. At this time, the valve body 208 is kept open by the buoyancy of the float 212 even if the operating force on the handle 216 is released, and the water level of the stored water (washing water) in the tank 200 drops and the Float 21 when it comes to the middle P ₁ position
As it descends, it sits on the valve seat 202 and closes the outlet 204.

On the other hand, when the handle 216 is rotated in the other direction (the opposite side) to the above, only the lever 222 provided on the pull-up shaft 214 is rotated this time, and the valve body 2 is rotated.
Only 10 is lifted via chain 226 and float 214. As a result, the flush water for the toilet inside the tank 200 is discharged to the toilet side through the opening of the valve body 208 and the discharge port 204.

When cleaning the toilet bowl during this piss, the tank 2
The float 214 descends with the decrease of the water level inside the valve 00, and when the float 214 reaches the position indicated by P ₂ in the figure, the valve element 210 is closed, and thereafter the cleaning water inside the tank 200 is washed. Discharge stops.

In the case of the toilet bowl cleaning apparatus of this example, it is not necessary to hold the handle 216 in the toilet bowl cleaning at the time of urination as well as in the toilet bowl cleaning at the time of stool.
Even if the user releases his or her hand immediately after operating 16, it is possible to reliably discharge a predetermined amount of water.
There is an advantage that there is no trouble of continuously holding 6 during the discharge time of washing water.

[0012]

On the other hand, however, in the case of the toilet bowl cleaning device, one valve element 208, 21 is provided for cleaning the toilet bowl during stool and the other is the valve body 208, 21 for cleaning the toilet bowl during urine.
0, floats 212, 214, chains 224, 226, levers 220, 222 are necessary, which inevitably complicates the structure and increases the cost, and especially chains 224 and 226 are entangled inside the tank 200. There is a problem, and as a result, there is a problem that the toilet bowl cleaning operation may not be performed properly.

Further, in the case of this toilet bowl cleaning device, the tank 2
00 The water level P ₁ at the end of discharging the water is the valve seat 2
No. 02 position (valve seat water level) P ₃ , that is, a position higher than the discharge port 204 position P ₃ , and as a result, the tank 200
There was a problem that the amount of residual water (dead water) inside was large and wasted, and the shape of the tank 200 was enlarged accordingly.

[0014]

The invention of the present application has been made to solve such a problem. Thus, the invention of the present application is: (a) a tank for storing a predetermined amount of flush water for a toilet; and (b) a drain seat at the bottom of the tank, which is seated or separated from a valve seat around the discharge port. A valve body that opens and closes, (C)
A float that moves up and down with the level of the washing water inside the tank and lowers the valve body together during the downward movement, and (d) directly or directly to the valve body with a connecting member such as a chain inside the tank. And a handle device for rotating the pull-up shaft to rotate the pull-up shaft to open the discharge port by rotating the pull-up shaft based on the applied operating force. In a toilet bowl cleaning device that flushes the inside of the tank by a valve opening operation of the valve body to perform toilet bowl cleaning, the handle device includes a connection portion of the connecting member of the pulling shaft with a handle of the handle device. In addition to rotating the valve body forwardly to the pulling position, a timer operation is performed after the operating force is released to lower the water level of the water in the tank to the valve seat position. Essential time or more and the preset time after the connection portion to the original position by backward rotation movement, characterized in that a timer means for closing the valve element Te following (claim 1).

According to another aspect of the present invention, in claim 1, the handle is rotatable in both forward and reverse directions from its original position, and the forward rotation of the forward side cleans the toilet bowl during a stool, and reversely. It is supposed that the toilet is washed at the time of urination by the forward rotation of the side, and the timer means performs the timer operation when the handle is rotated to the positive side, while rotating to the opposite side. The timer operation is not performed when it is operated, and the handle and the pulling shaft are in a free rotation state in both forward and backward rotation movements on the opposite side, and the valve body is set to the discharge water at the discharge port. The valve element can be pulled up to a position where the buoyancy of the float overcomes the suction force (claim 2).

[0016]

As described above, according to the first aspect of the invention, the connecting portion of the connecting member such as the chain of the pulling shaft is rotated forward to the pulling position of the valve body together with the handle of the handle device while operating. After the force is released, a timer is operated by a timer means to return the connection part to the original position after the water level of the water in the tank is lowered to the valve seat position.

That is, in the conventional toilet bowl cleaning device of this type, the valve body is closed in conjunction with the decrease of the water level in the tank, whereas in the present invention, the valve closing operation of the valve body is performed. Is performed independently of the decrease in the water level inside the tank.

Specifically, the valve means is closed by the timer means after the cleaning water in the tank is completely discharged to the position of the discharge port, that is, the position of the valve seat. According to the present invention, , The water level at the end of discharging the cleaning water inside the tank matches the valve seat water level, that is, the water level at the discharge port, and therefore the amount of water (dead water) remaining in the tank after the cleaning water discharge operation can be reduced. The minute tank can be downsized.

Further, in the present invention, since the valve body is closed after the water in the tank is completely drained, the set time of the timer means is set until the full water level reaches the valve seat water level. It is only necessary to set the time longer than the required time, so it is not necessary to increase the accuracy of the timer so much, and there is the advantage that variations in timer accuracy do not cause variations such as variations in the discharge amount of wash water inside the tank. is there.

According to a second aspect of the present invention, the handle of the handle device can be rotated in both forward and reverse directions, and the toilet bowl is cleaned on the regular side at the time of stool and the toilet bowl is cleaned on the opposite side at the time of urine. The timer means is made to operate at the time of rotating operation on the positive side, that is, at the time of toilet cleaning in the case of stool, and not to be operated at the time of urination.

In addition, when cleaning the toilet bowl during urination, the valve body is opened to a position where the float's buoyancy overcomes the suction force of the discharge water at the discharge port, and the cleaning water in the tank is discharged. When the water level drops, the valve body is closed together with the float that descends in conjunction with the water level. According to the present invention, when the toilet bowl is washed during urination, the handle of the handle device is It is not necessary to continue holding, and the operating force can be removed after the valve body is opened. Therefore, the operation for cleaning the toilet bowl during urine becomes very simple.

When cleaning the toilet bowl at the time of urine, the valve body closes as the water level of the wash water in the tank lowers. The sitting water level, that is, the position at which the water level is higher than the position of the discharge port. The water level at that time can be easily adjusted and set to an appropriate position by adjusting the relative position of the float with respect to the valve body when the valve body and the float are separately provided.

As described above, according to the present invention, the water level in the tank after the flush water is discharged can be made different between the flushing of the toilet bowl at the time of stool and the flushing of the toilet bowl at the time of urination. It is possible to discharge a large amount of wash water at times, and a smaller amount of wash water at the time of urination.
It is possible to properly clean the toilet bowl in both cases of urination.

In the present invention, it is not necessary to use separate transmission members such as valve bodies, floats, chains, etc. for cleaning the toilet bowl during stool and for cleaning the toilet bowl during urination. This has the advantages that the structure of the cleaning device can be simplified and the cost can be reduced, and there is no problem that the chain is entangled inside the tank and the normal toilet cleaning operation is impaired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 10 denotes a tank in which a ball tap 12 is arranged on the upper part and inside thereof. The ball tap 12 includes a water discharge port 14, a floating ball 16 that moves up and down with the water level in the tank 10, and a link mechanism 18 that transmits the vertical movement of the floating ball 16 to a valve body that controls water discharge and water stoppage from the water discharge port 14. have.

The ball tap 12 opens the valve body in accordance with the descending motion of the floating ball 16 when the flush water for the toilet in the tank 10 is discharged, and the ball tap 12 opens from the water discharge port 14 to the tank 10.
Supply water inside. On the other hand, when the water level inside the tank 10 rises and becomes full, the valve body is closed along with the upward movement of the floating ball 16 and the water discharge from the water discharge port 14 is stopped.

A discharge port 20 is provided at the bottom of the tank 10, and a valve seat 23 integrally assembled with the overflow pipe 22 is provided around the discharge port 20. Reference numeral 24 is a float valve in which a float and a valve body are integrally configured. One end of a chain 26 as a connecting member is connected to the float valve 24, and the float valve 24 is moved upward by the chain 26. It is designed to be pulled up.

Reference numeral 28 denotes a stopper ring for suppressing the floating amount of the float valve 24 to a fixed amount, which is fixed to the overflow pipe 22. Here, the stopper ring 28 is provided at a position where the buoyancy of the float valve 24 overcomes the suction force of the discharge water at the discharge port 20 when the float valve 24 floats.

A substantially horizontal pull-up shaft 30 is provided above and inside the tank 10, and the pull-up shaft 30 is further provided.
A handle device 32 is provided for rotating the. The handle device 32 includes a handle 34, and the handle 34 is arranged outside the tank 10. A lever 36 is integrally provided at the tip of the pull-up shaft 30, and the upper end of the chain 26 is connected to the lever 36.

The handle device 32 also includes the tank 10
A timer device 38 is provided inside the tank, and the timer device 38 is fixed to the inner surface of the tank 10 via a support bracket 40. This timer device 38
Is a timer operation for flushing the toilet bowl at the time of stool to return the pulling shaft 30 to its original position for a set time (5 seconds in this example). It is said that the timer does not operate.

The timer device 38 can be constructed, for example, as shown in FIG. In the illustrated example, the timer device 38 includes a cylindrical fixing member 42 that is fixed in position, a rotatable rotating member 44 disposed inside the fixing member 42, and an outer peripheral surface of the rotating member 44. And a friction member 46 that comes into frictional contact with the inner peripheral surface of 42 to generate a predetermined frictional force during the rotational movement of the rotation member 44.

Inside the fixed member 42, a transmission member 48 for transmitting the rotation of the pulling shaft 30 associated with the rotating operation of the handle 34 in the handle device 32 to the rotating member 44 is mounted, and the transmission thereof. A one-way clutch 50 that transmits the rotational movement of the transmission member 48 to the rotating member 44 by straddling the member 48 and the rotating member 44.
Is provided.

The one-way clutch 50 transmits the rotational movement of the transmitting member 48 in a specific direction to the rotating member 44 to rotate the rotating member 44 together, but does not transmit the rotational force to the rotating in the opposite direction, but transmits the rotational force. This serves to rotate the member 48 independently.

As shown in FIG. 2B, the transmission member 48 is provided with a notch 52 over a predetermined angle range, and within the notch 52, the notch 52 is formed integrally with the pull-up shaft 30. The protrusion 54 is relatively rotatable.

The transmission member 48 is also formed with a holding groove 56 for the ball 58, and the ball 58 is held therein. In the state shown in FIGS. (B) and (I), a part of the ball 58 projects into the notch 52, and the projection 54 on the pull-up shaft 30 has the projection 54 in the counterclockwise direction in FIGS. It prevents it from rotating freely. That is, in the state shown in FIGS. (B) and (I), the pull-up shaft 30 and the transmission member 48 rotate integrally in both clockwise and counterclockwise directions.

On the other hand, the inner peripheral surface of the fixing member 42 is formed with a concave portion 60 for retracting the ball 58 to the outer peripheral side at a certain position, and the ball 58 forms the concave portion 6.
Under the condition that the pull-up shaft 30 enters the inside of 0 and is pulled toward the outer peripheral side, the pull-up shaft 30, that is, the projection 54, is allowed to rotate independently in the notch 52 as shown in FIGS. There is.

Next, the operation of this example will be described. In the apparatus of this example, when the toilet user rotates the handle 34 from the neutral position (home position) to the left direction (clockwise direction) in FIG. (I) As shown in (I), the pull-up shaft 30 rotates forward together with the handle 34 in the same direction.
It is pulled up via 6 and the discharge port 20 is opened. As a result, the flushed water in the tank 10 is
The toilet is flushed from the outlet 20 toward the toilet side, and the toilet is cleaned.

At this time, the float valve 24 is once lifted up to a position where it comes into contact with the stopper ring 28 by the operating force applied by the handle 34, as shown in FIG. The weight 27 thus taken makes a gradual downward movement.

The specific operation is as follows. That is, the force of the return direction is applied to the rotating member 44 by the gravity of the weight 27, the pulling shaft 30, the transmitting member 48, the one-way clutch 50.
However, since the frictional force is generated by the friction member 46 at this time, the pulling shaft 30 cannot immediately return to the original position due to the frictional force, and gradually rotates to the original position over a certain period of time. Exercise (return rotation). In this example, the required time is 5 seconds. This time of 5 seconds is longer than the time required for the water level of the washing water inside the tank 10 which was full to fall to the position of the valve seat 23 (valve seat water level), that is, the position of the discharge port 20 P _1. Is also a long time.

Therefore, in this example, after the cleaning water in the tank 10 is completely discharged to the water level of P ₁ ,
The float valve 24 closes the discharge port 20, so that the amount of water corresponding to the water depth H ₁ from the water level when the water level is full to the position P ₁ is discharged.

On the other hand, when the handle 34 is rotated in the opposite direction to the above when cleaning the toilet bowl at the time of urine, at this time, as shown in FIGS. The protrusion 54 is separated from the transmission member 48 and independently rotates in the right direction in FIG. 2B, that is, in the counterclockwise direction.

As a result, the float valve 24 is sufficiently lifted up to the position where it comes into contact with the stopper ring 28 as shown in FIG.
It is discharged to the toilet side through 0. Then, when the level of the washing water in the tank 10 is lowered, the float valve 24 is lowered together with the fact that this is sensed, and finally the valve seat 23 is seated and the discharge port 20 is closed. The water level of the washing water in the tank 10 at this time is the position P ₂ in FIG. When the toilet bowl is washed at the time of urination, the pull-up shaft 30 independently rotates clockwise from the state shown in FIGS. 2 (B) and (II), that is, independently of the transmission member 48 and the rotation member 44. Return to original position.

When the toilet bowl is washed at the time of urination, the water level of the washing water in the tank 10 is finally at the position P ₂ in FIG. 1 when the float valve 24 is closed, and accordingly, at the time of urination. At the time of cleaning the toilet bowl, the cleaning water corresponding to the water depth H ₂ is eventually discharged.

As described above, according to the present embodiment, when flushing the toilet bowl at the time of stool, the water level when the flush water inside the tank 10 is completely discharged is P _{1 which} is the valve seat water level, that is, the drain port 20.
Nearby P ₁ is a water level, therefore possible to reduce the amount of water after discharge operation of the washing water remaining in the tank 10 (dead water),
The tank 10 can be downsized by that amount.

Also, in this example, since the float valve 24 is closed after the water in the tank 10 is completely drained, the set time of the timer in the timer device 38 is set so that the water level when full is the valve seat water level. It suffices to set the time longer than the time required to reach P _{1 in the above,} and therefore, it is not necessary to raise the accuracy of the timer so much, and the discharge amount of washing water inside the tank 10 also varies due to the variation in the timer accuracy. Such a problem does not occur.

Further, in this embodiment, when the toilet bowl is washed at the time of urine, the float valve 24 is opened to a position where the buoyancy of the float valve 24 overcomes the suction force of the discharged water at the discharge port 20. When performing toilet bowl cleaning,
It is not necessary to keep holding the handle 34 of the handle device 32, and the operating force can be removed immediately after the float valve 24 is opened. Therefore, the operation for cleaning the toilet bowl during urine becomes very simple.

Thus, according to this example, the water level in the tank after the flush water is discharged can be made different when the toilet is washed during stool and when the toilet is washed during urine. A large amount of flush water can be discharged at the time of urine, and a smaller amount of flush water can be discharged at the time of urine, so that the toilet bowl can be properly washed during both urine and urine.

In addition, in this example, it is not necessary to use separate transmission members such as valve bodies, floats and chains for cleaning the toilet bowl during stool and cleaning the toilet bowl during urination. This has the advantages that the structure of the device can be simplified and the cost can be reduced, and the problem that the chain 26 is entangled inside the tank 10 and the normal toilet cleaning operation is impaired does not occur.

The embodiment of the present invention has been described in detail above, but this is merely an example. For example, the timer device 38 illustrated above is merely an example of the present invention, and the timer device can be configured in various other forms.

In addition, the present invention can be applied to a toilet bowl cleaning device in which the valve body and the float are separate bodies, and can be configured in various modified forms without departing from the spirit of the invention. Is.
