Title: Cold water/hot water supplier
Inventor: ISHIZUKA HIROAKI
IPC: F25D13/00
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To miniaturize an apparatus and prevent waste use of electric power by providing a bypass line and a changeover valve in a circulation line of a cold water tank. SOLUTION: To a cold water tank 21 in which cooling means 22 is disposed there is connected a piping 24 at a portion of which pressure feed means 26 and a three-way changeover valve 25 are interposed, which piping constitutes a bypass line 42 together with a circulation line. When cold water is supplied to a heat exchanger 34 and a branket 35, the three-way changeover valve 25 is changed over so as to close the piping 42 to drive the pressure feed means 26. Hereby, cold water in the cold water tank 21 is supplied to the heat exchanger 34 after passage through circulation lines 36, 39, 43. In contrast, when hot water is supplied, the three-way changeover valve 25 is changed over so as to open the bypass line 42, and water is heated with heating means 41 and the pressure feed means 26 is driven.  Hereby, rapidly heated water is supplied to the heat exchanger 34 after passage through the bypass line 42 and the circulation line and returns to the heating means 41.

The signal line 3 connected to the series resonance circuits 15, 16 is separated by the insertion of the resistor 14. Even if the impedance of one series resonance circuit is lowered by the resonance of the trap frequency being a resonance frequency of one series resonance circuit, the signal line 3 connected to the other series resonance circuit is not a low impedance. Thus, the signal at a trap frequency is attenuated sufficiently in the 1st and 2nd series resonance circuits 15, 16.
