WATER SOFTENER AND CONTROL METHOD FOR WATER SOFTENER

원문 (중국어)

Water softener includes a soft water tank, a neutralization tank, bypass flow path that sends, as untreated water, raw water to a downstream side of the neutralization tank without passing the raw water through the soft water tank and the neutralization tank, mixer that mixes the untreated water sent from bypass flow path and the neutralized soft water sent from the neutralization tank to generate mixed water, flow rate adjustment unit that adjusts a supply amount of at least one of the untreated water and the neutralized soft water to mixer, and controller that controls a mixing ratio between the untreated water and the neutralized soft water by flow rate adjustment unit. Controller includes mixing ratio determination unit that determines the mixing ratio between the untreated water and the neutralized soft water based on instruction information related to at least one of a regeneration time during which a regeneration process can be performed and a water softening degree of the mixed water, and flow rate controller that adjusts the supply amount to be adjusted by flow rate adjustment unit such that the mixing ratio determined by mixing ratio determination unit is obtained.
