Description

  The present invention relates to a toilet flushing tank device for storing flush water in a flush tank, and in particular, a water supply delay mechanism for delaying and opening a water supply valve of a ball tap after opening a drain valve, and a flowing water spout for preventing freezing. It relates to what it has.

In a general toilet flushing tank device equipped with a ball tap inside, when the flushing water stored in the washing tank is discharged toward the toilet bowl by opening the drain valve, the ball tap float falls due to the drop in the water level. Open the water supply valve and start water supply to the tank immediately after opening the drain valve.
In this case, the water supplied into the tank by opening the water supply valve is also discharged from the discharge port of the cleaning tank toward the toilet together with the cleaning water stored in the tank, and used as toilet flushing water.

  However, the amount of wash water for toilet flushing is sufficient only for the amount of wash water originally stored in the wash tank, and even if new water is added and used for toilet flushing, It becomes an excessive amount of water, and a lot of water is discharged wastefully.

Therefore, instead of opening the water supply valve of the ball tap immediately after opening the drain valve and supplying water, a water supply delay mechanism for delaying the water supply valve after the drain valve is opened is provided. Has been proposed.
For example, Patent Document 1 below discloses a toilet cleaning tank apparatus provided with this type of water supply delay mechanism.

FIG. 9 shows a specific example.
In the figure, 300 is a toilet cleaning tank device, 302 is a cleaning tank, and 304 is a ball tap disposed therein.
Here, the ball tap 304 includes a water supply valve, a water supply port 306 that supplies water in the tank by opening the water supply valve, and a connecting arm 310 that connects the float 308 and the float 308 to the water supply valve.
Reference numeral 312 denotes a water supply delay mechanism, and reference numeral 314 denotes a small-capacity delay tank which is a main element.

The delay tank 314 has a small hole 316 at the bottom, and the cleaning water W ₂ inside the delay tank 314 flows out of the tank, that is, into the cleaning tank 302 through the small hole 316.
Reference numeral 318 is a discharge port at the bottom of the cleaning tank 302, and 320 is a drain valve for opening and closing the outlet.

In the toilet flushing tank device 300, although the cleaning water W ₁ which has been stored in the cleaning tank 302 opens the drain valve 320 is released all at once toward the discharge port 318 to the toilet bowl, flush water in the delay tank 314 Since W ₂ flows out little by little through the small hole 316, the water level of the cleaning water W ₁ descends rapidly, whereas the water level of the cleaning water W ₂ in the delay tank 312 decreases slowly, so that the drain valve 320 open cleaning water W ₁ and does not open the water supply valve of the ball tap 304 immediately be initiated release, water supply to the tank is not performed.

Here the timing of cleaning water W ₁ is entirely released by the drain valve 320 is closed, where the first water supply valve of the ball tap 304 on the basis of the decrease in the water level of the washing water W ₂ is opened, water supply to the tank is started (The size of the small hole 316, that is, the outflow rate from the small hole 316 is thus determined).
Therefore, in this toilet bowl cleaning tank apparatus 300, the water supply from the water supply port 306 after the drain valve 320 is opened can be prevented from being wasted as toilet flushing water.

  By the way, in cold districts, there is a problem that the water in the pipes and the trap part of the toilet bowl freezes, and as a toilet cleaning tank device used in cold districts, water is continuously supplied in a small amount to supply the toilet bowl. The thing provided with the flowing water outlet is used.

However, if the delay tank 314 is located at a position where the flowing water from the washing water spout falls, when the toilet bowl is washed in the flowing water spout, the flowing water enters the delay tank 314, thereby draining the water. Even if the valve 320 is opened and the cleaning water W ₁ stored in the cleaning tank 302 is discharged, the water level in the delay tank 314 does not decrease as planned.

  Specifically, when the flow rate of the flowing water entering the delay tank 314 is larger than the outflow rate from the small hole 316 of the delay tank 314, the water level in the delay tank 314 does not decrease indefinitely, and the delay tank 314 Even when the flow rate of the flowing water entering the inside is smaller than the flow rate flowing out from the small hole 316, the lowering of the water level in the delay tank 314 becomes slower than planned, and in any case, the drain valve 320 is opened. It becomes impossible to open the water supply valve of the ball tap 304 and supply water in the tank at an appropriate timing after the valve.

For example the water supply to the washing tank 302, finished releasing cleaning water W ₁ which had been stored inside opens drain valve 320, and it is desirable to perform drainage valve 320 is closed timing, such It becomes impossible to open the water supply valve at the right timing and start water supply.

One side wall 220 is provided with a notch 224 through which the connecting arm 30 is inserted. Further, the water receiving member 216 is provided with a claw portion 226 having elasticity that protrudes downward so as to protrude downward at the front end and the rear end (left end and right end in FIG. 6).
The water receiving member 216 is attached to the upper surface of the delay tank 200 by hooking the claw portions 226 to the above-described hook portions 214 of the delay tank 200 downward from above in the drawing.

  The water receiving member 216 has a recess 228 on the outer surface of the side wall 220 opposite to the side wall 220 on the side where the notch 224 is provided. The recess 228 is for avoiding interference with the arm 206 of the delay tank 200.

  As shown in FIG. 5, a draining portion 230 is fixedly provided on the arm portion 32 of the linkage arm 30 above the water receiving member 216. Here, the draining portion 230 is formed integrally with the arm portion 32.

  As shown in FIG. 7, the draining portion 230 has a plate shape that surrounds the arm portion 32 as a whole, and forms an upright portion 232 in which a portion above the arm portion 32 stands substantially vertically upward. The lower part forms an inclined part 234 that is inclined obliquely toward the center side of the water receiving member 216.

  Therefore, in this embodiment, although the flowing water from the flowing water spout 150 flows down through the connecting arm 30 of the ball tap 22, the flowing water is drained by the draining portion 230 in the middle of the arm portion 32. It is dropped on the member 216. Further, the water receiving member 216 guides outside the delay tank 200. Therefore, the flowing water from the flowing water outlet 150 is effectively prevented from entering the delay tank 200.

Specifically, the flowing water discharged from the flowing water outlet 150 flows along the arm portion 32 of the connecting arm 30 via the fixing nut 80, and the arm portion 32 is provided with a draining portion 230. The flowing water flowing along the outer surface of the arm part 32 is blocked by the draining part 230 and then dropped to the water receiving member 216.
The flowing water that has fallen on the water receiving member 216 is smoothly guided to the outside of the delay tank 200 and the inner tank 14 by the inclination of the bottom 218, and the flowing water is prevented from flowing into the delay tank 200.

In the later closing of the drain valve 15, the water level of the inner tank 14 inside the cleaning water W ₁ is raised by the water supply from the ball tap 22 and the water level is close filled with water, the inner tank 14 inside the cleaning water W ₁ flows into the delay tank 200 beyond the upper end of the delay tank 200 and is supplied into the delay tank 200.

  As described above, in the toilet bowl cleaning tank device 11 of the present embodiment, the flowing water from the flowing water outlet 150 can be prevented from entering the delay tank 200, and the water supply delay mechanism 202 can be operated normally. The opening of the water supply valve 58, that is, the timing of water supply in the tank can be maintained at an appropriate timing.

Further, this embodiment has an advantage that the flowing water outlet 150 and the delay tank 200 do not have to be displaced in the horizontal direction.
In the case where the flowing water is dropped into the tank through the linkage arm 30 of the ball tap device 22, the problem of the flowing water dropping into the stored water in the tank vigorously and generating a large landing sound there is avoided. On the other hand, in this case, it is necessary to position the flowing water outlet 150 at a position close to the horizontal direction directly above the delay tank 200 or above the delay tank 200.
Even under such circumstances, according to the present embodiment, it is possible to prevent generation of a large landing sound due to flowing water without forcibly shifting the position of the flowing water outlet 150 and the delay tank 200 in the horizontal direction. Both the normal operation of the water supply delay mechanism 202 can be realized.

  Further, according to the present embodiment, the flowing water that has flowed down along the linkage arm 30 is effectively dropped to the water receiving member 216 side at the draining portion 230, and the water receiving member 216 moves the water outside the delay tank 200. Can lead to.

FIG. 8 shows a reference example .
In this example , the flowing water from the flowing water outlet 150 is dropped directly into the inner tank 14, while the delay tank 200 of the water supply delay mechanism 202 is disposed with its horizontal position shifted with respect to the flowing water outlet 150. It is.
Also in this example, the flowing water from the flowing water discharge port 150 can be prevented from flowing into the delay tank 200 in the water supply delay mechanism 202, and therefore, the flowing water flows into the delay tank 200, whereby the water supply delay mechanism It is possible to prevent the operation set by 202 from failing to correctly execute the set operation.

Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, in the present invention, the water receiving member 216 in the first embodiment can be configured in various shapes other than the above example. For example, a pipe-shaped member is used as the water receiving member, and the flowing water discharged from the flowing water spout 150 is circulated through the pipe-shaped water receiving member as it is and guided to the outside of the delay tank 200 and the inner tank 14. It is also possible to do so.
In addition, the present invention can be applied to one having various other forms of flowing water outlets, and the present invention can be configured in various modifications without departing from the spirit of the present invention.
