A kind of drying machine stroke control method

Abstract

The invention discloses a method for controlling the stroke of a clothes drying machine. The corresponding relationship between the descending speed of the drying rod and the running current of a constant torque motor under different weight loads is pre-stored as a first relationship model, and the descending stroke of the drying rod is preset, and after the motor is started Obtain the starting time of the motor and the running current of the motor, query the first relational model to obtain the corresponding descending speed of the drying rod, and obtain the running time of the motor by dividing the preset descending stroke of the drying rod by the descending speed of the drying rod, which is calculated according to the starting point of the motor. When the motor is terminated, and control the motor to stop at the time when the motor is terminated. Through the above method, the stop position of the drying rod of the clothes drying machine can be automatically and accurately controlled without adding components or modifications to the structure or circuit of the clothes drying machine.

Description

technical field [0001] The invention relates to the technical field of clothes drying machines, in particular to a stroke control method of a clothes drying machine. Background technique [0002] The actual use process of the clothes drying machine may include: controlling the drying rod of the drying machine to descend, drying and hanging clothes, and controlling the drying rod of the clothes drying machine to rise. In the above process, the user usually controls the drying rod of the clothes dryer to descend to a height suitable for hanging the clothes, so that he can hang the clothes on the drying rod at the appropriate position without the need to adjust his own position greatly. form. [0003] There are several ways to control the descending stroke of the clothes dryer: [0004] One is to use the remote control or key switch to control, the user sends a signal to the drying machine through the remote control or key switch to control the descending, stopping and rising...

AI Technical Summary

Problems solved by technology

However, because the clothes dryer has different falling speeds when the load is different, the time recorded by the clothes dryer is only the falling time corresponding to its preset load. When the load changes, the same falling time will correspond to different falling times. height, so cannot always stay at the same height position

[0007] Therefore, there are certain defects in the existing clothes dryer formation control methods. Without adding built-in monitoring components, it is necessary to control the stroke of the clothes dryer so that it can stop at a preset height position. question
