At present, a traditional household dish washing machine needs to use hot water for washing, and a dish washing procedure is generally divided into three processes of main washing, cold water rinsing and hot water rinsing. Because hot water is needed for washing during washing, in order to avoid that calcium and magnesium ions in water form scale when being heated to influence the washing effect, a dish washer is generally provided with a water softener, tap water firstly passes through the water softener in the water inlet process, resin in the water is used for absorbing the calcium and magnesium ions in the water, and then the resin in the water is introduced into the machine, so that soft water washing is ensured, and scale generation is avoided. The water softener absorbs the calcium and magnesium ions of water through the resin, the water softener can be saturated after absorbing a certain amount of the calcium and magnesium ions, the softening capacity is lost after the water softener is saturated, at the moment, the resin is replaced and regenerated by the brine in the salt cavity of the water softener, and then the calcium and magnesium ions can be absorbed.
The dish washer integrates the functions of washing tableware, fruits and vegetables and seafood, the water for washing the tableware is less and is used for washing at high temperature, the water for washing the fruits and vegetables and the seafood for a single time is about 2L, the water for washing the fruits and vegetables and the seafood is more and is used for washing at normal temperature, the water for a single time is about 25L at most, scale is easy to generate during the high-temperature washing of the tableware, and soft water is needed for washing. Because the softening capacity of the water softener of the dish washer is limited, the water inflow rate is required to be 2.5L/min, if the water inflow rate is larger than the water inflow rate when fruits and vegetables are washed, the water inflow time can be greatly increased, meanwhile, the waste of water soft resources is caused, the use cost is increased due to the fact that the adding frequency of the regenerated salt of the water softener is increased by a user, and meanwhile, the service life of the water softener is also influenced.

after the cold water main washing is finished, the sewage generated by the cold water main washing is discharged into a sewer pipe, and then is communicated with the port B again to rinse the fruits and vegetables/seafood in the inner container of the dish washer, preferably cold water rinsing;
and after the cold water rinsing is finished, discharging sewage generated by the cold water rinsing into a sewer pipeline again, and finishing the cleaning operation of fruits, vegetables and seafood.
According to the water inlet method of the dish washing machine, through program setting, after a user selects a washing program, the dish washing machine can select whether water is fed through the water softener 400 according to whether hot water washing is performed at the stage, namely whether the water is communicated with an A port in the water inlet double valve 100, so that the waste of resources caused by the water body passing through the water softener 400 during cold water washing and cold water rinsing is avoided, the soft regeneration capacity of the water can be improved by more than 30%, and the service life of the water softener 400 is prolonged; in addition, the water inlet method saves the cleaning time of fruits and vegetables/seafood and improves the cleaning efficiency.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
