Inlet water anti-overflow control method of dish-washing machine and dish-washing machine

Abstract

The invention discloses an inflow water anti-overflow control method of a dish-washing machine and the dish-washing machine. The water inflow anti-overflow control method comprises the following steps that S1, the dish washing machine is in a standby state; s2, the real-time water level in the dish washing machine is detected; s3, the flow meter detects whether flow pulses exist in the dish washing machine or not, if yes, the step of fault processing is executed, and if not, the step S4 is executed; s4, judging whether a low-water-level switch of the dish-washing machine is triggered or not, if yes, entering a fault processing step, and if not, starting a draining pump to drain water in the dish-washing machine; s5, opening a water inlet valve; s6, the water inlet duration T2 is timed, and the pulse Wf1 of the flow meter is counted; s7, judging whether a low-water-level switch is triggered or not, and if yes, recording the pulse number Wf2 of the flowmeter at the moment; and S8, whether Wf2 is smaller than the lower limit water level Wfmin triggered by a low water level switch or not is judged, if yes, it is judged that the flowmeter is abnormal, and in addition, the fault processing step is executed. The dish-washing machine provided by the invention is operated by adopting the water inlet anti-overflow control method.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a method for controlling water inflow and overflow prevention of a dishwasher and the dishwasher. Background technique [0002] At present, the overflow detection of the dishwasher is generally realized through the high water level pressure switch, but in the actual application process, the high water level pressure switch is not accurate enough. The water level switch is not triggered, which leads to overflow; on the other hand, the dishwasher is also prone to accidentally triggering the high water level pressure switch during the water intake process, which in turn causes the water pump to drain water by mistake. [0003] Therefore, there is an urgent need for a water inflow and anti-overflow control method for dishwashers to solve the above problems. Contents of the invention [0004] The present invention aims to solve one of the problems existing in the related...
