Water softener regeneration control method and dish washing machine applying same

Abstract

The invention discloses a water softener regeneration control method and a dish washing machine applying the same. The method comprises the following steps that 1, after the washing process of the dish washing machine, a sodium chloride solution is supplied into a resin chamber for a replacement regeneration reaction; 2, the reaction is written into a marking program so as to memorize operation ofthe replacement regeneration reaction; 3, the dish washing machine stops; 4, the dish washing machine starts for the next time, whether or not a marking program memorizing the operation of the replacement regeneration reaction exists is detected, and if yes, the step 5 is executed; 5, the resin chamber is washed; 6, after the resin chamber is washed, the next dish washing machine washing processis executed; the dish washing machine is in a stop state in the replacement regeneration process, electric energy is saved, processing is more efficient, better performance is shown, and the control procedures are more refined.

Description

technical field [0001] The invention relates to the field of dishwasher control, in particular to a control method for regeneration of a water softener and a dishwasher using the same. Background technique [0002] General dishwashers are equipped with a water softener. The water entering the dishwasher chamber must first be softened by the water softener before entering the dishwasher chamber for use. Finally, after the washing process of the dishes and other tableware is completed, it will pass through the drain pump. Drive away. [0003] The water softener is provided with a resin chamber and a sodium chloride chamber, and the two are connected through a regeneration valve. The external tap water enters the resin chamber through the water inlet valve. The resin chamber is provided with resin for ion exchange. When the tap water passes through the resin When the water softener is used for a period of time, it can filter out mineral ions such as calcium and magnesium in th...

Problems solved by technology

[0004] However, in the water softener regeneration, it takes a long time for the sodium ions in the sodium chloride to undergo a replacement reaction with the resin, and after the conversion reaction is completed, it is necessary to flush the resin with water again

[0005] In the previous control process of dishwashers, the process of replacing and regenerating the resin cavity is generally selectively added after the washing process of tableware such as tableware. During the replacement and regeneration reaction, the dishwasher is always in the starting state. After the replacement reaction is sufficient, start the drain pump to drain the water away, which will cause the dishwasher to take a long time to start after the washing process is completed. First, it consumes more power. Second, it is reflected in the lack of replacement regeneration time. The performance effect is poor, resulting in worsening water softening effect, which in turn leads to worsening washing effect, which cannot be accepted by consumers
