A control method of a water softener of a dishwasher and the dishwasher

Abstract

The invention provides a control method of a water softener of a dishwasher and the dishwasher. Operation stages of the dishwasher comprises a reduction stage of the water softener, wherein the reduction stage involves a salt washing process, a resin reduction process, a first saline water discharging process and a second saline water discharging process; the first saline water discharging processand the second saline water discharging process are carried out after the salt washing process and the reduction process; the first saline water discharging process and the second saline water discharging process are respectively completed after previous washing and before next washing; when the dishwasher enters the first saline water discharging process, a water pump of the dishwasher inputs residual water in a water tank of the dishwasher into a resin cavity of the water softener, discharges high concentration saline water in the resin cavity out of the dishwasher, and then halts; the second saline water discharging process is carried out before the dishwasher enters a next washing stage, when the dishwasher enters the second saline water discharging process, the water pump inputs partial water in the water tank during next washing into the resin cavity and then discharges the residual high concentration saline water in the resin cavity out, so that the use experience of a user isimproved.

Description

technical field [0001] The invention relates to a control method of a water softener of a dishwasher and the dishwasher. Background technique [0002] The existing dishwasher with a water softener, after working for a period of time, the resin in the water softener absorbs a certain amount of calcium and magnesium ions, and the water softening ability and effect will become poor, which requires regeneration to make the resin on the The calcium and magnesium ions detach from the ability to restore softened water again. In the final stage of this regeneration, it is necessary to use a large amount of water to drain away the brine containing calcium and magnesium ions. Use a large amount of water at one time to drain away the brine containing calcium and magnesium ions. If the remaining water in the water tank is insufficient after washing, this will lead to incomplete drainage of brine or the need to manually add water. If it is before the start of washing, the amount of washi...

Use a large amount of water at one time to drain away the brine containing calcium and magnesium ions. If the remaining water in the water tank is insufficient after washing, this will lead to incomplete drainage of brine or the need to manually add water. If it is before the start of washing, the amount of washing water will Insufficient, it also needs to manually add water twice, which brings a lot of trouble to the user and takes up a lot of washing water
