Control method of clothes treating equipment

Abstract

The invention discloses a control method of clothes treating equipment, and belongs to the technical field of household appliances. The clothes treating equipment is provided with a rotatable washing barrel. The control method comprises a barrel rotating step of driving the washing barrel to rotate at a first rotating speed v1, so that clothes in the washing barrel are tightly attached to the inner side wall of the washing barrel; and a cloth quantity detection step of driving the washing barrel to do accelerated motion and / or decelerated motion to judge the cloth quantity, wherein the first rotating speed v1 is higher than the maximum rotating speed of the washing barrel in the cloth quantity detection step. The barrel rotating step is arranged before the cloth quantity detection step, and the first rotating speed v1 of the washing barrel in the barrel rotating step is higher than the maximum rotating speed of the washing barrel in the cloth quantity detection step; under the centrifugal effect of high-speed rotation, the clothes in the washing barrel are tightly attached to the inner side wall of the washing barrel; the rotation radius of the clothes is close to the radius of the washing barrel, and the rotation radius tends to a stable value; then the cloth quantity detection step is carried out; and the rotational inertia and the clothes mass are approximately linear, and the rotational inertia can accurately reflect the clothes mass.

Description

【Technical field】 [0001] The invention relates to the technical field of household electrical appliances, in particular to a control method of a clothes processing device. 【Background technique】 [0002] The washing machine can adjust the injection water level and the amount of detergent according to the quality of the placed clothes to ensure that the clothes are in the best washing state. The quality of the clothes can be obtained by detecting the amount of cloth. The time, current and other parameters required for the motor to accelerate or decelerate to another speed under different loads are used to measure the rotational inertia, according to the formula J=mr 2 (where J is the moment of inertia, m is the mass, and r is the radius of rotation). When the radius of rotation r is fixed, the mass is basically proportional to the moment of inertia, so that the moment of inertia can be converted into mass. What is measured by this method is the sum of the moment of inertia o...

Problems solved by technology

What is measured by this method is the sum of the moment of inertia of the drum and the clothes. The moment of inertia of the clothes part is related to the distribution of the clothes in the drum. The fluffier the clothes, the more uniform the distribution, the smaller the moment of inertia generated. The closer it is to the inner wall of the washing tub, the greater the moment of inertia will be. When the load increases, although the quality of the clothes is increasing, the radius of rotation r decreases due to the increase in the volume of the clothes. As a result, the moment of inertia increases when the load increases. The amount of change is reduced, and it is difficult to show a linear increase between the moment of inertia and the quality of the clothes, resulting in a decrease in the accuracy of cloth amount detection
