Method for controlling stroke of clothes dryer

Abstract

The invention discloses a method for controlling stroke of a clothes dryer, and the method comprises the following steps of pre-storing the correspondence relationship between the descent speed of a drying rod and the running current of a constant torque motor under different weight loads as a first relationship model, setting the descent stroke of the drying rod in advance, obtaining the startingtime and running current of the motor after the motor is started, querying the first relationship model to get the corresponding descent speed of the drying rod, obtaining the running time of the motor by dividing the descent speed of the drying rod by the descent stroke of the drying rod set in advance, calculating the terminating time of the motor through the cooperation with the starting timeof the motor, and controlling the motor to stop at the terminating time of the motor. Through the above method, without adding components or modifying the structure or circuit of the clothes dryer, the stop position of the drying rod of the clothes dryer can be automatically and accurately controlled.

Description

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

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
