HOT-WATER SUPPLYING METHOD OF HOT WATER SUPPLIER PROVIDED WITH FUNCTION OF BATHTUB HOT-WATER POURING OPERATION AND HOT-WATER SUPPLYING OPERATION

摘要

PURPOSE: To obtain the hot-water supplying method of a hot-water supplier provided with functions of bathtub hot-water pouring operation and hot-water supplying operation, which is capable of effecting general supply of hot-water having a temperature higher than a set temperature for said hot-water pouring easily even during the bathtub hot-water pouring operation. ;CONSTITUTION: In a hot-water supplier provided with the function of bathtub hot-water pouring operation, hot-water is supplied by a method wherein water from a water inlet passage 20 is heated by a heat exchanger 11 to discharge it into a hot-water discharging passage 30 and supply it for general hot-water supplying while a bathtub hot-water supplying passage 50 is branched from the hot-water discharging passage 30 and another bathtub water supplying passage 60 is branched from the water inlet passage 20 to pour hot-water into a bathtub. When the bathtub hot-water pouring operation and the general hot-water supplying operation are effected simultaneously, a general hot-water supplying set temperature TQS is compared with a hot-water pouring set temperature TFS and a higher temperature is set as a discharging hot-water set temperature TS. When the hot-water pouring set temperature TFS is lower, the hot-water of the bathtub hot-water supplying passage 50 is mixed with the water from said bathtub supplying water passage 60 to regulate the hot-water pouring set temperature TFS through feedback control.;COPYRIGHT: (C)1994,JPO&Japio
