Title:
POWER SOURCE FOR ELECTROLYTIC WATER PREPARATION MACHINE
Document Type and Number:
Japanese Patent JP3539458
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simplify a circuit and a wiring and manufacture a machine, inexpensive and of high performance.
SOLUTION: A triac 30 is connected with the primary side of a power source transformer 32, and its power applying phase is controlled by a first control circuit 31 to control the direct current voltage. A center tap 32a is provided on the secondary side of the power source transformer 32 and connected with an electrode 36b of an electrolytic cell 36. The output of a diode bridge 33 connected with the secondary side of the power source transformer 32 is connected with switch elements 34 and 35, and a connecting point 38 of the switch elements is connected with an electrode 36a of the electrolytic cell 36. Diodes D1-D4 of the diode bridge 33 are used in the sets of two pieces respectively as same polarity, and either of + and - direct current voltages which are full-wave rectified based on the center tap 32a of the power source transformer 32 as a reference is applied to the electrode.
