A method of controlling a dishwasher

Abstract

A method for controlling a dishwasher, characterized in that it includes the following steps: step 1, initializing settings; step 2, judging whether there is water in a sink of the dishwasher; step 3, detecting the failure of a drain valve; step 4, entering water Valve fault detection; Step 5, judge whether the water intake reaches the preset water intake L; Step 6, judge whether the motor reaches the set speed V0; Step 7, judge the motor failure; Step 8, detect the speed V of the spray arm 臂 ; Step 9, the spray arm stuck fault; Step 10, the sub-process of adjusting the speed of the spray arm. The invention has the advantages that the motor speed can be adjusted adaptively according to the water intake, thereby reaching a predetermined spray arm speed range, and finally achieving the best cleaning effect.

Description

technical field [0001] The invention relates to a dishwasher, in particular to a dishwasher control method with adjustable rotation speed of a spray arm. Background technique [0002] Dishwasher is a device used to automatically clean dishes such as bowls, chopsticks, plates, dishes, knives, forks, etc. It reduces labor intensity and improves work efficiency. At present, various dishwashers have been launched and are gradually entering the common family. In actual work, the motor controls the rotation of the spray arm, and the high-speed water flow sprayed by the rotation of the spray arm cleans the tableware in the dishwasher. In the prior art, for example, the existing patent application for invention with the application number of 201510742463.X "A Dishwasher Sprinkler and Dishwasher Equipped with the Sprinkler and Control Method" relates to a dishwasher sprayer. A shower, which includes a horizontally arranged spray arm, and at least one spray hole is arranged on the s...

Problems solved by technology

However, during the cleaning process of the above-mentioned patent, the rotation speed of the spray arm is uncontrollable, and the state of the spray arm (such as whether it is installed in place, whether it is stuck, and the real-time speed of the spray arm) cannot be detected in real time, nor can it be based on the spraying arm. The status of the spray arm is realized by adjusting the motor speed in real time, and the speed of the spray arm will directly affect the cleaning effect. During the working process, it may not reach the set speed due to various reasons. The cleaning speed of this spray arm is uncontrollable. way, will reduce the cleaning effect
