Cleaning machine and working method thereof

Abstract

The invention relates to a cleaning machine which comprises a tank body. A partially concave draining part is arranged at the bottom of the tank body, and a water outlet is arranged at the bottom of the draining part. The draining part is covered with a filter screen. A first turbidity sensor is arranged at the part, located outside the draining part, of the bottom of the tank body, and a second turbidity sensor is arranged at the bottom of the draining part. The cleaning machine further comprises a controller which is respectively in communication connection with the first turbidity sensor and the second turbidity sensor. The invention further relates to a cleaning method of the cleaning machine. Turbidity data detected by the first turbidity sensor before water enters the cleaning machine and turbidity data detected by the first turbidity sensor after water is drained from the cleaning machine are compared, turbidity data detected by the second turbidity sensor before water enters the cleaning machine and turbidity data detected by the second turbidity sensor after water is drained from the cleaning machine are compared, then whether the cleaning machine is blocked or not is determined according to the comparison results, and if the cleaning machine is blocked, the blocking position and the blocking degree are determined. The intelligent degree of the cleaning machine is higher.

Description

technical field [0001] The invention relates to the technical field of washing machines, and the invention relates to a washing machine and a working method of the washing machine. Background technique [0002] The existing dishwashers basically perform cleaning work according to the set fixed cleaning program, and the cleaning intelligence is low. The application publication number is CN107854094A (application number is 201711195682.6) Chinese invention patent application "Sink Dishwasher and Its Cleaning Control Method". And when the washing program is not completed, the washing water volume during washing is adjusted according to the turbidity of the washing sewage in the current bowl basket, and the washing times of the washing program are updated. In the Chinese invention patent application with application publication number CN108784585A (application number 201810519038.8), the disclosed cleaning method also detects the change of turbidity over time during the cleanin...

Problems solved by technology

[0003] However, these cleaning methods can only adjust the cleaning mode based on the detection of the turbidity of the dishwashing water, and usually the turbidity of the water is determined by the detection value of a single turbidity sensor in the dishwasher, and there is often a misjudgment of the cleanliness resulting in waste of resources or unclean washing

Moreover, the application of these turbidity data is single, and it is impossible to judge more situations in the dishwasher, which limits the scope of its data application
