<P>PROBLEM TO BE SOLVED: To provide a water softening system capable of reducing power consumption by efficiently utilizing a DC power supply disposed on the water softening system. <P>SOLUTION: A DC power supply device 102 disposed on a hot water supplier 100 is connected to a control part of a water softener 1 by DC power supply lines 104, and a controlling power supply generated on the basis of the DC power supply supplied via the DC power supply lines 104 is supplied to a microcomputer 50 of the water softener 1. When the water softener 1 gets to an operation mode of a small current consumption, for example, water-obtaining mode, the supply of a source power supply 56 for a DC power supply device 55 disposed on the water softener 1 is intercepted by a source power supply interception means 59 and, thereby, the power consumption on the DC power supply device 55 is suppressed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
