WASHING WATER SUPPLY DEVICE, WASHING WATER TANK DEVICE WITH THE WASHING WATER SUPPLY DEVICE, AND FLUSH TOILET BOWL WITH THE WASHING WATER TANK DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a washing water supply device capable of preventing occurrence of trouble where, before a stop water level within a washing water tank reaches a specified water level required for washing a toilet bowl, a water level within a small tank rises and a float is moved up to close a water supply valve on earlier stage, thereby stopping water supply.;SOLUTION: A washing water supply device 22 comprises a diaphragm type water supply valve 36, a small tank 38 and a float 42. In the water supply valve 36, a pilot hole 36f is formed which extends substantially horizontally while communicating with a water supply pipe 34 extending upwards from a bottom face of a water storage tank 18. The water supply valve 36 is provided at an upper side of and by the side of the water supply pipe so as to switch supply/stop of water into the water storage tank by opening/closing the pilot hole. The small tank 38 stores washing water therein while opening the upper side thereof and being fitted to the water supply pipe. The float 42 is moved vertically in accordance with fluctuation of a water level within the small tank, such that the water supply valve is caused to open/close the pilot hole. The small tank and the float are disposed oppositely to a side where an outlet 36g of the pilot hole 36f in the water supply valve is positioned, with respect to the water supply pipe.;COPYRIGHT: (C)2014,JPO&INPIT
