Embodiment Construction

[0039] An embodiment of the method of controlling the operation of the dishwasher according to the turbidity of washing water according to the present invention will be described with reference to the drawings.

[0040] The structure of the dishwasher according to the present invention is the same as that of the prior art, so detailed description of the structure will be omitted. And the composition of the dishwasher is represented by the same graphic symbols as those of the prior art.

[0041] The method for controlling the operation of the dishwasher according to the turbidity of the washing water is as follows: Figure 5 shown.

[0042] First, the user inputs a corresponding operation command after considering the quantity and type of tableware to be washed.

[0043] After the user inputs the operation start command, the washing water is supplied to the set water level under the control of the control unit (6) (S10, S20).

[0044] At this time, the set water level of the...

Abstract

The present invention is method of controlling operation of dish washing machine according to the turbidity of washing water, and has compensation function on the turbidity detecting error caused by the error of the turbidity detecting sensor. The method includes the stage of supplying washing water to the set level based on the washing command of the operator; the stage of detecting the first turbidity of the washing water; the stage of the second turbidity of circular washing water during pre-washing; and the stage of controlling the washing operation based on the detected first turbidity and the second turbidity. Compensating the turbidity detecting error can raise the washing performance of dish washing machine and the system reliability.

Description

technical field [0001] The invention relates to a method for controlling the operation of a dishwasher, in particular to a method for controlling the operation of the dishwasher according to the turbidity of washing water. Background technique [0002] Generally speaking, a dishwasher is a machine used to automatically wash food residues attached to tableware after a meal. [0003] Such as figure 1 and figure 2 As shown, the dishwasher in the prior art comprises: a button input unit (1) for inputting a user-designated operation command; a control unit (6) for controlling the operation of all systems of the dishwasher according to the button signal of the button input unit (1); Drive the load driving part (2) of various loads (3) such as the washing motor (3a), the water supply valve (3b) and the drain valve (3c) driven according to the control signal of the control part (6); A water level sensing part (4) for water level; a turbidity sensing part (5) for sensing the turb...
