Title:
WATER HEATER
Document Type and Number:
Japanese Patent JP2017020659
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem that when a flow sensor 10 counting a flow rate is disposed at a downstream side of a flow rate adjustment valve 12, as water is not uniformly brought into contact with an impeller as a detection portion of the flow sensor 10 due to uneven water flow caused by throttling of a flow channel by the flow rate adjustment valve 12, the difference is found between the detection value detected by the flow sensor 10 and an actual flow rate value actually passing through the flow sensor.SOLUTION: Water flow unifying means is disposed at a downstream side of a hot water supply mixture valve 7, and a flow sensor 10, a supply water temperature sensor 11, and a flow rate adjustment valve 12 are successively disposed at a downstream side of the water flow unifying means.SELECTED DRAWING: Figure 1
