WATER CIRCUIT CHANGEOVER VALVE DEVICE FOR ELECTROLYTIC WATER MAKER

摘要

PURPOSE: To achieve the miniaturization and wt. reduction of the subject device by making it possible to operate a control water circuit controlling the supply of water to an electrolytic cell, an intake circuit of electrolyzed water, a purifying water circuit utilizing raw water or purified water and a washing water circuit purifying the electrolytic cell only by performing the changeover operation of a lever passage changeover mechanism by a lever. ;CONSTITUTION: A first fixed valve member 10 having a pair of the raw water passing holes 9a, 9b separately communicating with a raw water supply passage 3a and an electrolytic water maker water supply passage 3b formed thereto and a second fixed valve member 13 having the passing holes 11a, 11b separately communicating with the electrolyzed water discharge passages 3c, 3d from an electrolytic water maker 8 and the passing hole 12 communicating with a water emitting passage 4 formed thereto are provided to the valve chamber 5 of the passage changeover mechanism 6 of the changeover valve device 1 provided to the electrolytic water maker 8. A pair of the left and right valve rolls 16, 17 attached to an operation rotary shaft 15 in an integrally rotatable manner so as to be opposed to the outsides of the respective fixed valve members 10, 13 in a contact state are provided. The pipelines 3a, 3b are selectively opened and closed by the rotation of the valve roll 16 and the pipelines 3c, 3d are selectively opened and closed by the rotation of the valve roll 17.;COPYRIGHT: (C)1995,JPO
