Description

  The present invention relates to a cleaning tank apparatus for storing toilet flushing water, opening a drain valve to discharge the flushing water, and washing the toilet bowl, and more particularly, a reinforcement for supplying makeup water from a ball tap to an overflow pipe Related to water hose.

Conventionally, as shown in FIG. 6, this type of cleaning tank apparatus has been used.
In the figure, reference numeral 200 denotes a washing tank, and a hand-washing basin 202 that also serves as a lid is provided on the upper part. The handwashing bowl 202 is provided with a handwashing water discharge pipe 204 standing upright.
Handwash water from the handwash water discharge tube 204 falls into the handwashing basin 202 and then falls into the washing tank 200 through a drain hole at the bottom of the handwashing basin 202.

Reference numeral 206 denotes a ball tap disposed inside the cleaning tank 200, which performs water supply and water supply stop in conjunction with the lifting and lowering of the floating ball 208.
That is, when the floating ball 208 is lowered, the valve portion of the ball tap 206 is opened, and water is supplied into the cleaning tank 200 through the water discharge pipe (strictly, a conduit for guiding water from the water discharge port of the ball tap 206 downward).
On the other hand, as the water level in the cleaning tank 200 rises, the floating ball 208 rises, and when the water surface becomes full, the valve portion of the ball tap 206 is closed to stop water supply.

  Further, a water conduit (not shown) made of a bellows tube extends from the ball tap 206, and its distal end is connected to the hand wash water discharge tube 204. Water is supplied to the water discharge pipe 204.

A float valve (drainage valve) 214 is provided at the bottom of the cleaning tank 200.
The float valve 214 has a spherical valve body 216 and a valve seat 218, and an L-shape that rotates integrally with a cleaning handle 220 provided on the tank wall of the cleaning tank 200 with respect to the valve body 216. The distal ends of the action levers 222 are connected via a chain 224.
Thus, when the washing handle 220 is rotated, the float valve 214 lifts the valve body 216 from the valve seat 218 and opens the valve portion. Here, the washing water in the washing tank 200 passes through the discharge port 226 to the toilet. To be released.

  In the cleaning tank device of this example, a makeup water pipe 232 extends from the ball tap 206, and makeup water can be supplied into the overflow pipe 230 through this makeup water pipe 232.

The reason why the water from the ball tap 206 is supplied into the overflow pipe 230 as make-up water is as follows.
That is, in the case of a siphon-type toilet, when flushing the toilet stored in the washing tank 200 and discharging the toilet, the accumulated water in the drain trap portion of the toilet is discharged to the downstream side at once due to the siphon phenomenon. .
Then, supply water is supplied to the drain trap portion inside the toilet bowl through the overflow pipe 230 and the discharge port 226, thereby preventing the sealing water from being cut off at the drain trap portion.

However, when the toilet bowl is not a siphon toilet bowl or the like, it is not necessary to supply makeup water into the overflow pipe 230 by the makeup water hose 232. Therefore, conventionally, in such a case, connection of the makeup water hose 232 is not necessary. It responded by using a ball tap without a mouth.
However, in this case, separate ball taps are used for the siphon toilet bowl and the case where the siphon toilet bowl is not, and there is a problem that the flush water tank device cannot be commonly used for the siphon toilet bowl and the other toilet bowl.

  Therefore, in the previous patent application (Patent Document 1), the present applicant has a first connection port through which the water supplied from the makeup water hose flows into the overflow pipe, and a second insertion port through which the water flows out of the overflow pipe and into the tank. A holder separate from the overflow pipe is attached to the upper end of the overflow pipe, and when the supply of makeup water is unnecessary, the tip of the makeup water hose is connected to the second insertion port and held. We propose a cleaning tank system that is designed to be kept.

However, in this case, the number of necessary parts increases, and it is difficult to handle the makeup water hose in the tank when the tip of the makeup water hose is connected to the second connection port and held. Will occur.
In addition, when the make-up water hose is connected to the second insertion port, the water supply from the make-up water hose will fall on the water surface in the tank as it is, so that no drop sound of the water supply will be generated at that time. Special ingenuity is required for this purpose.

JP 2002-167836 A

The present invention is based on the circumstances as described above, and can be used in common for siphon toilets and toilets that are not, and even when no supplementary water is supplied from the supplementary water hose, extra parts are required. In addition, the present invention has been made for the purpose of providing a cleaning tank device equipped with a makeup water hose that is easy to route the makeup water hose in the tank.
Another object of the present invention is that when the water supplied from the make-up water hose is returned to the tank, the water from the make-up water hose may hit the parts in the tank, etc. The object is to provide no wash tank equipment.

Accordingly, the present invention provides a cleaning tank apparatus in which a makeup water hose for supplying makeup water is extended from a ball tap disposed inside the washing tank into an overflow pipe inside the washing tank. An insertion port for inserting and holding the tip of the replenishing water hose is integrally formed on the tank wall of the tank, and water supplied from the replenishing water hose is allowed to flow into the tank through the insertion port. Ri Oh provided an outlet, before Symbol outlet is not a tubular body having an opening at the upper end, characterized in that the longitudinal notches of the said outlet along the cylindrical peripheral wall is provided.

According to a second aspect of the present invention, in the first aspect , the notch is provided in a direction in which water flowing out from the notch does not reach any of a float valve, a ball tap, and a floating ball inside the cleaning tank.

According to a third aspect of the present invention, in any one of the first and second aspects, the bottom surface of the cylindrical body is an inclined or curved surface extending obliquely downward toward the inside of the tank.

Effects and effects of the invention

  As described above, according to the present invention, the insertion port for inserting and holding the tip of the makeup water hose is integrally formed on the tank wall of the cleaning tank. If it is not necessary to supply makeup water into the overflow pipe, the tip of the makeup water hose may be inserted into the insertion port. Therefore, the cleaning tank apparatus of the present invention is not so even if it is a siphon type toilet. Even toilet bowls can be used in common.

In addition, since this insertion port is formed integrally with the tank wall, when no makeup water is supplied to the toilet, that is, when water is not supplied into the overflow pipe, there is no need for a separate part for holding the tip. The cost of the cleaning tank device can be reduced.
In addition, when inserting and holding the tip of the makeup water hose, this insertion port can be selected and determined at a position where the makeup water hose does not interfere with the components in the tank. It is possible to satisfactorily avoid interference with the other parts in the tank.
In addition, the supply water hose can be easily routed in the tank.

  Further, according to the present invention, since the insertion port is provided in the tank wall, the water supply from the makeup water hose can be gently poured out along the tank wall, and the makeup water from the makeup water hose is stored in the tank. It is possible to effectively prevent water noise from falling on the water surface from above the central portion.

In the present invention, the outlet constitutes this in the cylindrical body, and along the cylindrical wall provided with a longitudinal notch as above outlet Contact Ku.
Further, the notch can be provided in such a direction that the water flowing out from the notch does not reach any of the float valve, the ball tap and the floating ball inside the washing tank (claim 2 ).
In this way, when the makeup water from the makeup water hose is returned to the tank, the spilled water from the outlet of the outlet hits parts such as the float valve, ball tap, and floating ball in the tank and splashes. As a result, it is possible to prevent the splashed water from leaking out of the tank or generating water noise in the tank.

Next, a third aspect of the present invention is the one in which the bottom surface of the cylindrical body forming the insertion port is an inclined or curved surface extending obliquely downward toward the inside of the tank. Water can smoothly flow out to the inner surface of the tank wall by the guiding action of the bottom surface, and when the make-up water from the make-up water hose is returned to the tank, the make-up water hits parts in the tank or falls to the water surface. In this case, it is possible to more effectively prevent the generation of water noise.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
1 and 2, reference numeral 10 denotes a cleaning tank in the cleaning tank apparatus 11 according to the present embodiment, which has a double tank structure including a ceramic outer tank 12 and an inner resin tank 14 inside thereof.
A ceramic hand-washing basin 16 that also serves as a lid is provided at the upper part of the outer tank 12, and a hand-washing water discharge pipe 18 is provided in a standing manner in the hand-washing basin 16.
A drain outlet 20 is provided at the bottom of the hand basin 16, and water dropped into the hand basin 16 from the hand-washing water discharge pipe 18 falls into the washing tank 10 from the drain outlet 20.

A ball tap 22 is disposed inside the cleaning tank 10.
The bow tap 22 has a valve portion connected to a floating ball 26 via an interlocking arm 24. The valve portion is opened and closed by raising and lowering the floating ball 26, and water supply and water supply to the cleaning tank 10 are performed by opening and closing the valve portion. Stop.
From the ball tap 22, a water discharge pipe (to be exact, a conduit for guiding water from the water discharge port) 23 extends to supply water into the cleaning tank 10. Further, water is supplied from the ball tap 22 to the hand washing water discharge pipe 18. The water guide pipe 30 consisting of a bellows pipe for carrying out is extended, and its tip is inserted and connected to the hand-washing water discharge pipe 18.

A float valve (drain valve) 32 is disposed at the bottom of the cleaning tank 10.
The float valve 32 has a spherical valve body 34 and a valve seat 36, and the valve body 34 is lifted from the valve seat 36 to open the discharge port 38. The valve body 34 is seated on the valve seat 36. By doing so, the discharge port 38 is closed.

On the other hand, a cleaning handle 40 is rotatably provided on the tank wall (side wall portion) of the cleaning tank 10.
As shown in FIGS. 1 and 2, an action lever 42 having an L shape extends from the cleaning handle 40 into the cleaning tank 10, and the tip of the lever and the valve body of the float valve 32 are connected to the water receiving cup 46. Are connected by a chain 44 via
Here, the water receiving cup 46 has a function of switching between large washing (washing at the time of stool) and small washing (washing at the time of urine) by accumulating water or emptying the inside. It is designed to move up and down integrally.

As shown in FIG. 1, the water receiving cup 46 is provided with a cylindrical portion 48, and the cylindrical portion 48 is externally fitted to the overflow pipe 50 so as to be vertically slidable.
The water receiving cup 46 and the valve body 34 move up and down under the guide of the cylindrical portion 48 and the overflow pipe 50.
Here, the overflow pipe 50 is for overflowing the water in the washing tank 10, and the overflow water flows out from the lower end of the overflow pipe 50 to the toilet through the discharge port 38, bypassing the float valve 32.

As shown in FIGS. 1 and 2, a makeup water hose 52 for supplying makeup water to the overflow pipe 50 extends from the ball tap 22.
The replenishing water hose 52 is inserted into the insertion port 54 at the upper end of the overflow pipe 50 so that a part of the water from the ball tap 22 is supplied into the overflow pipe 50, that is, to the toilet bowl. Supply as makeup water.

As shown in FIGS. 3 to 5, when the makeup water hose 52 is not used for supplying makeup water to the overflow pipe 50 on the tank wall of the cleaning tank 10, specifically, the tank wall of the inner tank 14. The insertion port 56 for inserting and holding the tip portion is integrally formed.
Here, the insertion port 56 is formed of a cylindrical body, and is arranged in the recess 58 so that the lower end thereof is higher than the water surface position P (see FIG. 1) when the washing tank 10 is full of water. .

The insertion port 56 is provided with a notch 60 that serves as an outlet for make-up water from the make-up water hose 52 from the upper end to the lower end along the peripheral wall.
Here, as shown in FIG. 4, the direction of the notch 60 is the center of the cleaning tank 10 with respect to the wall of the tank wall, specifically, the direction perpendicular to the wall of the tank wall where the insertion port 56 is provided. It is formed obliquely in the opposite direction so that the effluent water from the notch 60 does not reach any of the float valve 32, the ball tap 22, and the float 26 in the cleaning tank 10.
As shown in FIGS. 3 and 5, the bottom surface 62 of the insertion port 56 is an inclined surface extending obliquely downward toward the inside of the cleaning tank 10.

In the cleaning tank device 11 of the present embodiment, when the makeup water hose 52 is not used for supplying makeup water into the overflow pipe 50, its tip is inserted into the insertion port 56 provided in the tank wall. Let me hold.
In this case, when the valve portion of the ball tap 22 is opened and water is supplied into the cleaning tank 10, a part thereof also flows into the makeup water hose 52.
Thus, the water that has flowed into the makeup water hose 52 flows into the insertion port 56, and then returns to the cleaning tank 10 from the vertical notch 60 that is the outlet.
At that time, the water in the insertion port 56 smoothly flows out to the inner surface of the tank wall by the guide action of the bottom surface 62 formed of an inclined surface, and flows downward along the inner surface of the tank wall.

  Further, as shown in FIG. 4, the notch 60 is oriented obliquely toward the direction where the various functional components in the cleaning tank 10 are not located, so that water in the insertion port 56 passes through the notch 60. When the spilled water flows into the cleaning tank 10, the spilled water hits the float valve 32, the ball tap 22, or the floating ball 26, and splashes, and the splash leaks out of the cleaning tank 10 or on the water surface in the cleaning tank 10. It does not cause problems such as falling and making water noise.

  Further, in the present embodiment, since the insertion port 56 is provided in the tank wall, when the tip of the makeup water hose 52 is inserted into the insertion port 56, the makeup water hose 52 extends in the horizontal direction. Thus, the amount of upward protrusion is small or the upward protrusion is not caused, so that the replenishing water hose 52 is well prevented from interfering with the hand basin 16 also serving as a lid.

  As described above, according to the present embodiment, when there is no need to supply makeup water from the makeup water hose 52 into the overflow pipe 50, the tip of the makeup water hose 52 can be inserted into the insertion port 56. Therefore, the washing tank device 11 of the present invention can be used in common for both siphon type toilets and other types of toilets.

  In addition, since the insertion port 56 is formed integrally with the tank wall, a separate part for holding the tip portion is provided when the makeup water is not supplied to the toilet, that is, when the supply water is not supplied into the overflow pipe 50. This is not necessary, and the cost of the cleaning tank device 11 can be reduced.

  In this embodiment, since the insertion port 56 is provided in the tank wall, the water supplied from the makeup water hose 52 can be gently poured out along the tank wall, and the makeup water from the makeup water hose 52 is washed into the washing tank. It is possible to effectively prevent water sounds and splashes from falling on the water surface from above the central portion in 10.

  Further, since the bottom surface 62 of the cylindrical body forming the insertion port 56 is formed as an inclined surface (may be a curved surface) extending obliquely downward toward the cleaning tank 10, replenishment from the replenishing water hose 52 is performed. The water can smoothly flow out to the inner surface of the tank wall by the guide action of the bottom surface 62, and when the makeup water from the makeup water hose 52 is returned into the washing tank 10, the makeup water hits the components in the washing tank 10 or It is possible to more effectively prevent water noise from being dropped when falling on the water surface.
