Example Embodiment

[0027] In order to easily understand the technical means, creative features, purpose and effect of the present invention, the present invention will be further explained in conjunction with specific drawings below.

[0028] Such as figure 1 As shown, a weighing method applied to a sensorless pulsator washing machine. The pulsator washing machine includes a motor for driving the rotation of the inner drum and an upper computer MCU electrically connected to the motor. The pulsator washing machine rotates without water before starting washing Two full turns, use the upper computer MCU to obtain the magnitude of the motor phase current, and calculate the cumulative current value Is of the motor running one full revolution, the cumulative current value Is of the motor is calculated by the fitting formula, and the upper computer MCU stores The corresponding relationship between each fitted value and the corresponding weighing weight. The pulsator washing machine determines the weighing ...

Abstract

The invention discloses a weighing method applied to a non-sensor pulsator washing machine and belongs to the technical field of household appliances. The washing machine is the pulsator washing machine and comprises a motor for driving an inner drum to rotate and an upper computer MCU electrically connected with the motor, the pulsator washing machine rotates multiple times before washing is started, and in the period, whether or not the motor is in a blocked operation state is judged; if yes, the operation time of the motor is acquired; if the motor normally operates, an accumulation current value of the motor during a whole circle of operation is calculated; according to the two states, by using the operation time or accumulation current value of the motor, the weight is obtained through weighing and transmitted to the upper computer MCU, and the upper computer MCU gives a proper water level. According to the weighing method, for the pulsator washing machine, under the condition of not additionally increasing the material cost, garments in the drum can be weighed, the upper computer MCU automatically gives the proper water level, and the operation difficulty of a user is lowered.

Description

technical field [0001] The invention relates to a weighing method applied to a sensorless pulsator washing machine, which belongs to the technical field of household appliances. Background technique [0002] For traditional pulsator washing machines, the water level setting is generally set by the man-machine interface. It is divided into multiple water levels or the default standard water level. If the water level is set high, it will cause waste of water resources. If the water level is set low, it will cause excessive friction on the clothes. The clothes are severely worn, but the traditional washing machine does not have a weighing device on the hardware, and the water level cannot be accurately determined according to the amount of clothes. In order to solve this problem, a weighing method applied to a sensorless pulsator washing machine is proposed . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a weighi...
