System and method for controlling lifting spray arm of dish washer based on three-dimensional scanning

Abstract

The invention provides a system for controlling a lifting spray arm of a dish washer based on three-dimensional scanning for solving the problem that the washing capacity of the dish washer in the prior art is limited and the cleaning dead angle easily occurs. The system comprises a signal judging module for judging whether a cleaning starting signal of the dish washer is received or not, a three-dimensional scanning module for scanning a to-be-washed object in the dish washer three-dimensionally after receiving the cleaning starting signal of the dish washer and storing a three-dimensional scanning result, a stroke calculating module for calculating a spray stroke corresponding to the lifting spray arm of the dish washer and a spray driving module for spraying and cleaning the to-be-washed object. By arranging a plurality of annular spray arms facing the water nozzles in the water tank, arranging the spraying stroke according to the to-be-washed object and spraying and washing the to-be-washed object according to a pre-set spraying mode, the spray arm sprays water more precisely and is free of cleaning dead angles.

Description

technical field [0001] The invention relates to the technical field of dishwasher cleaning, in particular to a system and method for controlling the lifting and lowering spray arms of the dishwasher based on three-dimensional scanning. Background technique [0002] At present, the existing dishwashers usually use the upper and lower spray arms to rotate and spray for washing. In this washing method, there will be dead angles, and partial washing may not be clean. [0003] When the parts are not clean, the tableware cannot be kept in the dishwasher for a long time, otherwise bacteria will be produced and cause harm to the human body; the user's secondary cleaning is also time-consuming and laborious. [0004] However, the current dishwashers capable of all-round three-dimensional cleaning have a fixed process of controlling the cleaning in all directions, and cannot clean objects to be washed in the dishwasher, and cannot clean objects to be washed in different positions. ...

Problems solved by technology

[0003] When the parts are not cleaned, the tableware cannot be stored in the dishwasher for a long time, otherwise bacteria will be generated and cause harm to the human body; the user's secondary cleaning is also time-consuming and laborious

[0004] At present, the dishwasher capable of all-round three-dimensional cleaning has a fixed process of controlling the cleaning in all directions, and it cannot be cleaned for the objects to be washed in the dishwasher, and the objects to be washed in different positions cannot be cleaned.

[0005] In the prior art, there is also a device in which the spray arm can be lifted and lowered in the dishwasher, which is used for comprehensive spraying to improve the disadvantages of the fixed spray device, and then the spray arm can be lifted and lowered. At present, the stroke of the spray arm is also fixed, which cannot reach Combined with the spray washing of the object to be washed, the washing effect is not very good
