[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cleaning tank apparatus for storing toilet flush water and opening the drain valve to discharge the flush water to wash the toilet bowl.
[0002]
[Prior art]
Conventionally, as shown in FIG. 8, this kind of cleaning tank apparatus has been used. In the figure, reference numeral 200 denotes a cleaning tank, and a hand-washing basin 202 that also serves as a lid is provided on the upper part thereof.
A hand-washing water discharge pipe 204 is provided upright from the hand-washing bowl 202. 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.
[0003]
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 210.
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.
[0004]
From the ball tap 206, a water conduit 212 made of a bellows tube extends, and its tip is connected to the hand rinsing water tube 204. Water is supplied to 204.
[0005]
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 the valve body 216 rotates integrally with a cleaning handle 220 provided on the wall portion 200 </ b> A of the cleaning tank 200. The tip of the character-shaped action lever 222 is 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.
[0006]
In this example, the water receiving cup 228 is continuously provided on the upper side of the valve body 216 in the float valve 214 so as to move up and down integrally.
Here, the water receiving cup 228 is for switching between large washing and small washing, and when the water receiving cup 228 is empty, the time until the valve body 216 sits on the valve seat 218 and closes the valve portion is reached. It is long and therefore a large amount of washing water is discharged from the outlet 226 during this period.
[0007]
On the other hand, in a state where water is accumulated in the water receiving cup 228, the water receiving cup 228 functions as a weight, and thereby the valve body 216 lifted from the valve seat 218 quickly descends and the valve seat 218 is moved. Sit on. Accordingly, in this case, the discharge amount of the washing water is reduced.
The water receiving cup 228 moves up and down together with the valve body 216 using the overflow pipe 230 as a guide.
[0008]
As shown in FIG. 9, the cleaning tank apparatus of this example has a conduit pipe holder 232. The water guide tube holder 232 has a fitting hole 234, and the tip end portion of the water guide tube 212 made of a bellows tube is fitted into the fitting hole 234 to hold it.
The water conduit holder 232 has a hook 238 at the end of the arm 236, and the hook 238 is hooked to the wall 200A of the cleaning tank. That is, it is attached to the cleaning tank by being hooked by the hook 238.
[0009]
By the way, in this kind of washing tank apparatus, as shown in FIG. 10, when the drainage from the drain hole 240 at the bottom of the hand basin 202 falls directly into the washing water in the washing tank 200, a waterfall sound is generated there. . This falling sound is annoying noise.
[0010]
Therefore, in the prior art as shown in FIG. 10, a silencing member for guiding the drainage from the drainage hole 240 to the inner surface of the wall portion of the inner tank 200-2 provided inside the outer tank 200-1. 242 is provided to prevent the generation of a falling sound of drainage from the drainage hole 240.
[0011]
[Problems to be solved by the invention]
However, when the water conduit holder 232 and the sound deadening member 242 are separately configured and attached to the wall portion of the cleaning tank 200 as described above, the number of parts for the cleaning tank device increases, and the cleaning tank device is more expensive. It becomes.
Further, as shown in FIG. 10, when the cleaning tank 200 has a double tank structure of an outer tank 200-1 and an inner tank 200-2, the inner tank 200-2 is made of resin. In this case, the inner tank 200-2 is likely to be deformed after molding, which has caused the following disadvantages.
[0012]
That is, when the inner tank 200-2 is deformed, depending on the shape and arrangement of the floating ball, the floating ball comes into contact with the inner surface of the inner tank 200-2 when the floating ball is raised and lowered, thereby generating a resistance. The problem that an up-and-down movement is obstructed occurs. Alternatively, various parts are assembled in the inner tank 200-2 in a predetermined positional relationship. If the inner tank 200-2 is deformed at that time, the inner parts 200-2 and the inner tank 200-2 are deformed. The tip of the action lever that rotates in unison with the cleaning handle interferes with the wall of the inner tank 200-2 as the case may be. Various inconveniences such as a change in the tank capacity due to the deformation of the inner tank 200-2.
