Abstract

The invention provides a method for detecting a drainage failure of water use equipment and mainly aims to solve defects existing in existing water use equipment which applies a water level switch or a water level sensor to detect drainage failures. The invention provides a detection method, wherein measurement signals of a turbidity sensor can be used to monitor drainage situations when no water level switch or water level sensor exists, so whether a drainage system has failures can be determined. The detection method provided by the invention has the advantages that a drainage detection algorithm is combined and used to motor drainage situations, so the water level switch or water level sensor is not needed, and the cost is reduced; and a new function of detecting a drainage water level, namely the function of detecting whether the drainage has the failures is developed besides a pollution degree detection function and a temperature detection function of the turbidity sensor.

Description

technical field [0001] The invention relates to a method for detecting drainage failure of water equipment, in particular to a method for detecting drainage failure by using a turbidity sensor. Background technique [0002] At present, the dishwasher judges the water level by using a water level switch or a water level sensor to control the water level during the water intake and drainage stages by using pressure or electromagnetic principles, and then detects drainage failures. [0003] The drainage system of the dishwasher is usually installed with a pressure conduit at the bottom of the sink, and the pressure conduit is connected with a water level switch or a water level sensor. During the draining stage, the drain pump works, the water level in the sink continues to drop, the air pressure inside the machine continues to decrease, and the gas pressure Passed to the water level switch or water level sensor through the pressure conduit. When the water level drops to the s...
