Problems solved by technology
[0003] The present invention aims at technical problems such as the inability to obtain the corresponding weighing curve when the existing fuzzy weighing method is applied to the washing machine, especially the large-capacity pulsator washing machine, and proposes a new technical solution; the production is corrected by correcting the friction of the system. Differences in weighing curves caused by the inconsistency of some parts between washing machines and washing machines during use; and add water replenishment algorithm to correct the weighing value, so that the pulsator washing machine can accurately determine the load weight

The invention relates to a method for judging the load weight of a pulsator washing machine, which can solve the problem of the inconsistency of weighing curves among the same model of washing machines through a system friction correction function. The method comprises the following steps: inputting a signal to a washing machine procedure controller after a washing procedure is started, and driving a motor to rotate and stop, wherein a group of back electromotive force pulses can be generated after the motor is stopped, and a computer board carries out fuzzy weighing judgment through reading the quantity of the pulses; and finally correcting in a water-replenishing manner to finally judge the load weight. The method has the benefits that the function of intelligently judging the clothing weight of the pulsator washing machine, in particular a large-capacity pulsator washing machine is realized, the water inlet level can be automatically selected, the washing performance is improved, and the washing procedure is optimized.
Description
technical field [0001] Embodiments relate to a method of determining the load weight of a top-loading washing machine. Background technique [0002] The existing method for judging the load weight of the pulsator washing machine uses the method of collecting the back electromotive force of the motor. Input a signal to the program controller of the washing machine to drive the motor to turn and stop. After the motor stops, a set of back electromotive force pulses will be generated. By collecting the pulse values generated by the back electromotive force of the motor with different loads, it can be fitted into a scale under each belt tension. heavy curves. Use the weighing value of the empty bucket to determine the current belt tension, and select the corresponding weighing curve; after the laundry program is started, the motor drives the pulsator to rotate, and the load weight is determined by comparing the weighing value with the curve value. The method is simple and eas...
