Document Type and Number:
Japanese Patent JP2015105773
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a water supply device which estimates a water level of a water supply tank by using a simple structure without using a water level sensor that detects the water level of the water supply tank.SOLUTION: A water supply device includes: a water supply tank (11); an atmospheric open type water receptor (310) to which water is supplied from the water supply tank by using a hydraulic head pressure; a flow speed detection part which detects a flow speed of the water supplied from the water supply tank (11) to the water receptor (310); and a water level estimation part which estimates a water level of the water supply tank (11) on the basis of the flow speed of the water which is detected by the flow speed detection part.
