Abstract

The invention belongs to the technical field of water draining controlling of dish washing dishes and provides a dish washing machine and a water draining control method and device thereof. Firstly, a motor in a draining pump of the dish washing machine is controlled to run within the preset water draining time; secondly, the motor is controlled to run within first reserved water draining time, the working current of the motor is detected, a corresponding remaining water value is acquired from a preset database according to the rotating speed and the working current of the motor, whether the remaining water value is smaller than a preset remaining water threshold value or not is judged, if yes, the motor is controlled to run within second reserved water draining time and then controlled to stop working, and if not, the motor continues to be controlled to run within the first reserved water draining time; thus, the water draining time can be accurately controlled by judging the remaining water, the problem that noise becomes higher due to idle draining of the draining pump when no water exists is avoided, the service life of the draining pump is prolonged, and the washing circulating time of the dish washing machine is shortened.

Description

technical field [0001] The invention belongs to the technical field of dishwasher drainage control, and in particular relates to a dishwasher and a drainage control method and device thereof. Background technique [0002] At present, the drainage method of the existing dishwasher is to use the controller to regularly control the on-off of the drainage pump to perform the drainage operation. Since the residual water in the inner tank of the dishwasher cannot be judged, in order to ensure complete drainage, the existing technology uses the After the preset drainage time is over, reserve redundant drainage time (for example, the preset drainage time is 20 seconds, and the redundant drainage time is 60 seconds), and control the drainage pump to continue draining during the redundant drainage time, so that the remaining The water in the dishwasher drains completely. However, the prior art will bring the following three problems: [0003] (1) If the water has been completely dis...
