HOT WATER FEEDER

摘要

PURPOSE:To enable a desired hot water of high temperature to be attained as fast as possible after starting a feeding-out the hot water by a method wherein a control means for performing a hot water feeding operation of a hot water feeder in response to a hot water feeding start instruction, and starting a returning of hot water by a returning means is provided. CONSTITUTION:As a hot water feeding plug 1 is opened, a hot water feeder 2 starts a hot water feeding operation under a condition in which it is responded to a plug opening of a hot water feeding plug 1 with a water flow switch 7 being ON. A hot water returning pump 14 is energized while it is responded to an opened plug 1 in response to a reduced hot water temperature in a hot water shoring tank 12 so as to start a returning of the hot water. By this fact, although a part of the remained low temperature water flowing into the tank 12 is mixed with the stored hot water remained in the tank 12, the hot water is not fed out toward the plug 1, but it is returned back to the hot water feeder 2 through a returning pipe 13. Due to this fact, a flow rate per unit time in the hot water feeding pipe 13 reaching the tank 12 is increased more than an amount of fed-out hot water per unit time from the plug 1 by an amount of returning flow from the returning pipe 13, resulting in that the hot water reaches from the hot water feeder 2 to the tank 12 within a short time, so that a time in which the hot water temperature increases up to the desired hot water and recovered to the hot water temperature is shortened.
