Title:
WATER FLOW SWITCH AND HOT WATER DEVICE
Document Type and Number:
Japanese Patent JP2018097929
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a water flow switch capable of suppressing erroneous detection even when a flow rate of hot water that flows in the water flow switch temporarily fluctuates.SOLUTION: A water flow switch according to an embodiment of the present invention includes a case that includes an inlet port through which hot water flows into, an outlet port through which hot water flows out, and an inner wall surface, and that is connected to the inlet port and the outlet port and provided with a flow path defined by the inner wall surface therein and a flapper that includes a flapper main body and an axis that rotatably supports the flapper main body in a direction from the inlet port to the outlet port in the flow path. The case includes a first rib that protrudes from the inner wall surface toward the flow path. The first rib is disposed between a part in which the inlet port and the flow path are connected to each other, and a part in which the outlet port and the flow path are connected to each other.SELECTED DRAWING: Figure 1
