Title:
WATER SOFTENING DEVICE AND WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/014670
Kind Code:
A1
Abstract:
A washing machine disclosed herein includes a hardness component remover disposed in a treated water path between a water supply source and a detergent supply case to soften hard water supplied from the water supply source and supply the softened water to the detergent supply case. The hardness component remover includes a downstream buffer space, an upstream buffer space, and a resin filling chamber disposed between the downstream buffer space and the upstream buffer space and filled with an ion exchange resin. A control device performs regeneration processing for regenerating the ion exchange resin by supplying saturated regenerated water to the hardness component remover. During the regeneration processing, the control device mixes the saturated regenerated water with water in the downstream buffer space to generate adjusted regenerated water having a regeneration concentration lower than a saturation concentration, and passes the ion exchange resin.
