Title:
DRAIN FORCED-FEED TOILET
Document Type and Number:
Japanese Patent JP3237189
Kind Code:
B2
Abstract:
PURPOSE: To stop the feed of water to a low tank by closing a solenoid valve on the water feed side and to announce the occurrence of abnormality by means of a lamp when a draining forced-feeding tray is brought into a state to be incapable of washing owing to a piping trouble on the water feed side.
CONSTITUTION: A water feed solenoid valve 11 is located in a water feed passage 7 to a low tank 3, a float switch 14 in the low tank 3, and a solenoid valve 8 between the low tank 3 and a closet 2, and a crusher 9 is connected to the drain port of the closet 2. A storage tank 12 is connected to the crusher 9, and a forced feed pump 10 and a float switch 13 are arranged in the storage tank 12. A control part 16 controls operation of the solenoid valves 8 and 11, the crusher 9, and forced-feed pump 10 by means of input signals to the float switches 13 and 14 and a washing switch 15. Thus, during use in a state that the feed of water to the low tank 3 is insufficient during water failure and at a place where a water feed pressure is low, detection of abnormality is not effected, malfunction is prevented from occurring, and only original failure in operation on the original water feed side is detected to stop the whole of a system.
