Description

  The present invention relates to a cleaning apparatus for removing urine from toilet bowls (particularly flush toilet bowls).

  The urine stones in the urinal cause clogging of the piping and cause odor. Therefore, as a method for removing urolith, it has been proposed to arrange a urolith remover in the urinal, and various urolith removers have been developed.

  However, the urinary stone removing agent cannot be placed in the toilet bowl and cannot be used for removing the urinary stone from the toilet bowl. In addition, there has been a demand for a means that can remove urine stones more reliably without simply removing urine stones by simply placing the urine stone removal agent in the urinal.

  The present invention has been made in consideration of the above-described matters, and an object of the present invention is to provide a cleaning device that can reliably remove urinary stones from a toilet bowl regardless of whether it is a urinal or a toilet bowl.

In order to achieve the above object, the cleaning device of the present invention is provided in a supply pipe for supplying cleaning water to a toilet, and is configured to dissolve the urolith remover in the cleaning water flowing in the supply pipe. Thea is,
An outer case,
An inner case provided in the outer case and containing the urolith remover;
A pipe part penetrating the bottom of each of the outer case and the inner case, extending in the vertical direction, and having an upper end positioned in the inner case;
The washing water from the upstream side of the supply pipe flows from the lower part of the pipe part to the outside of the pipe part through the inside of the pipe part, and then flows out of the pipe part to the outside of the pipe part. Flows out of the inner case from the through hole provided in the side wall, and further flows out of the outer case from the through hole provided in the bottom of the outer case toward the downstream side of the supply pipe. Configured so that the opening of the pipe portion is at a position higher than the through hole provided in the side wall of the inner case,

  A urine stone removing agent 30 is accommodated in the inner case 18. The urine stone removing agent 30 has a substantially cylindrical shape, and a hole 31 for allowing the tube portion 19 to pass therethrough is provided at the center. The urine stone removing agent 30 may be any one that dissolves in the washing water supplied to a normal flush toilet, and various types can be used.

  As shown in FIGS. 1 and 2, the flush valve 2 is operated by a button 2a. While the button 2a is being pushed by a finger or the like, the wash water flowing in the supply pipe 4 moves downstream of the flush valve 2. When the button 2a is released, the flow rate of the cleaning water gradually decreases, and an amount of the cleaning water corresponding to the push-in depth of the button 2a flows to the downstream side of the flush valve 2. After that, the flow is configured to stop automatically. As shown in FIG. 2, the downstream joint 34 of the flush valve 2 is connected to the supply pipe 4 connected to the urinal 3 by, for example, a cap nut 35. The flash valve 2 is a known one and will not be described in more detail.

  Next, the flow of the cleaning water introduced from the supply pipe 4 into the cleaning device 1 will be described. The cleaning water first flows from the upstream joint 8 into the upstream space 11. Thereafter, the washing water flows into the inner case 18 from the opening 29 at the upper end of the pipe part 19 through the through hole 14 provided in the partition wall 10 and the pipe part 19.

  When the urine stone removing agent 30 contained in the inner case 18 is dissolved in the washing water that has flowed as described above, and a certain amount or more of washing water flows into the inner case 18, the washing water overflows. It flows out of the inner case 18 from the through hole 26 provided in the side wall of the inner case 18, and flows down between the inner case 18 and the outer case 17. Subsequently, it reaches the downstream space 12 of the base 5 through a through hole 23 provided in the bottom of the outer case 17 and is finally led out from the downstream joint 9 to the downstream side, that is, the flash valve 2.

  Therefore, in the urinal 3 in which the cleaning device 1 is attached to the supply pipe 4, the urine stone removing agent 30 is dissolved in the cleaning water in the inner case 18 of the cleaning device 1 until it becomes saturated, and the button of the flash valve 2 is Every time the 2a is operated, the washing water in which the urine stone removing agent 30 is dissolved is supplied to the urinal 3, thereby preventing the urine from being generated in the urinal 3 and the urine stone fixed to the urinal 3 being removed. Will be removed.

  Here, since the urine stone removing agent 30 is consumed by dissolution in the washing water, it needs to be replenished. And the washing | cleaning apparatus 1 of this Example is the state which can replenish the urine stone removing agent 30 in the inner case 18 by removing the cap 21 of the outer case 17, and also removing the cap 25 of the inner case 18. It becomes. Accordingly, if a new urine stone removing agent 30 is dropped into the inner case 18 in this state, the replenishment is completed. At this time, it is not necessary to collect the old urine stone removing agent 30 accommodated in the inner case 18.

  In addition, when the urolith remover 30 is replenished as described above, the caps 21 and 25 are respectively attached to the main body 20 of the outer case 17 and the main body 24 of the inner case 18 by screwing. It can be removed by rotating it in the opposite direction. When removing the cap 25, the cap 25 can be rotated by grasping the handle 27 provided on the upper surface thereof, so that there is a gap between the inner case 18 and the outer case 17. The cap 25 can be easily attached to and detached from the main body 24 of the inner case 18 even when it is narrow and a finger cannot be inserted.

  In the cleaning device 1 having the above-described configuration, the check valve 16 is built in the upstream joint 8, so that the cleaning water containing the urolith removing agent 30 dissolved in the inner case 18 is upstream of the cleaning device 1. Returning can be reliably prevented.

  In the above-described embodiment, the cleaning device 1 is applied to the flush toilet 3. However, the present invention is not limited to such a configuration, and the cleaning device 1 may be applied to a flush toilet.
