Vorrichtung zur Verteilung von kaltem/heissem Wasser.

摘要

This invention relates to a cold/hot water discharging apparatus which is used for cold/hot water massage shower, and the like. In order to alternately switch and supply hot water of a predetermined temperature supplied from a hot water source (6) to a discharge portion, a valve (5) of a cold/hot water mixing tap (A) is driven by a motor (12) and is reciprocated in a pre-set period between a position where high temperature hot water is discharged and low temperature hot water is discharged. In each of the periods for discharging low/high temperature hot water, an optimum gain of this period is determined from the previous period and previous gain so as to shorten the discharge period of cold/hot water and to obtain a stable curve of the discharge hot water.
