PROBLEM TO BE SOLVED: To solve the problem that: a spiral tube is located adjacently on a water supply side and a drain side, the amount of stored water is small and used mainly for carrying and sufficient water cannot be expected even if the spiral tube is connected; and both of water supply and drain are in a lower part, and a water supply plug and a drain plug have to be opened in an emergency to inconveniently take out water by a half each.SOLUTION: A water storage device, in which water supply tubes having a same water storage function as that of a removable tank are integrally overlapped with each other in a state capable of conducting water, is interposed in the middle of the water supply path of a conventionally used water supply pipe. Thereby, the above-described problem is solved while maintaining a normal water supply in the normal case. |
