A dishwasher and washing control method thereof

Abstract

The invention discloses a dish-washing machine and a washing control method thereof. The dish-washing machine comprises a water tank, a water adding device used for injecting water into the water tank, a spraying device and a liquid level sensor used for detecting the low liquid level of the water tank, and the washing control method comprises the washing steps: a constant-speed operation step: awashing pump operates at a preset rotating speed; and a water level detection step: when the liquid level sensor continuously detects that the water tank is always at a low liquid level within a period of time, the rotating speed of the washing pump is reduced, and whether the actual water level in the water tank is at the low liquid level or not is judged. According to the invention, when the water level is detected to be low in the washing process, the rotating speed of the washing pump is reduced firstly, the water level rises again, water level fluctuation becomes small, then detection continues, the problems that water level fluctuation is large and water level detection is prone to misjudgment in the washing process are solved, water level detection accuracy and reliability are improved, and frequent water supplementing or no water supplementing caused by misjudgment of the water level is avoided.

Description

Technical field [0001] The present invention relates to a household appliance, and more particularly to a dishwasher and its washing control method. Background technique [0002] Dishwasher in the washing process, the water level fluctuation is large, and the water level is not accurate. If the user places the tableware, some tableware is correct, the water will fall into the correct cutlery through the spraying process, which cannot circulate into the glass, which will cause the water level to be too low and there is a heat-free dish to dry or wash the pump. Affect the reliability of the whole machine and the washing effect. Inventive content [0003] It is an object of the present invention to provide a dishwasher and its washing control method to solve the technical problems mentioned in the background art. [0004] In order to achieve the above object, a specific technical solution of a dishwasher and a washing control method thereof is as follows: [0005] A washing control...

AI Technical Summary

Problems solved by technology

If the tableware placed by the user is not standardized, some of the tableware is placed upright, the water will fall into the upright tableware during the spraying process through the spray arm, and cannot circulate into the water cup, which will cause the water level to be too low and cause the heating plate to dry or the washing pump to run dry. Affect the reliability of the whole machine and the washing effect
