Problems solved by technology

[0010] The disadvantage of the opening and closing mechanism of the washing water flow path of the above-mentioned existing dishwasher is that: the upper flow path 26 and the lower flow path 28 are respectively provided with a check valve 34a and a check valve 34b, and the check valve 34a and the check valve 34b is also equipped with expensive solenoid valve 36a and solenoid valve 36b to work respectively, which increases the production cost of the dishwasher
In addition, both the solenoid valve 36a and the solenoid valve 36b need electricity to control, which not only consumes electric energy, but also has hidden dangers of electrical connection failure.
