Limit stroke adjustable clothes airing machine and adjusting method thereof

Abstract

A limit stroke adjustable clothes airing machine comprises a winding wheel, a load-carrying steel wire wheel wound around the winding wheel, a motor for driving the winding wheel to rotate, a Micro Controller Unit (MCU), a rotating plate, a level leaping detection module, and a limit adjusting signal module. The MCU outputs a motor control signal to control the motor to rotate, driving the clothesline pole of the clothes airing machine to ascend and descend. The rotating plate is arranged on a rotating shaft which is driven by the motor to rotate. Induction points are uniformly arranged on the rotating plate at the circumference. The level leaping detection detects the induction points on the rotating plate and provides outputs. The MCU adjusts the e clothesline pole of the clothes airing machine to ascend to the highest set point or descend to the lowest set point according to the limit adjusting signal module. The MCU inputs level leaping signals output by the level leaping detection module, and records N level leaping signals corresponding to the limit stroke of the clothes airing machine. The invention also provides a limit stroke adjusting method. According to the invention, the limit stroke can e adjusted according to the floor height, and the danger caused by adjusting the lowest descending position at high altitude is avoided.

Description

technical field [0001] The invention relates to a clothes dryer with adjustable limit stroke and an adjustment method thereof. Background technique [0002] With the rapid development of smart clothes dryers, smart clothes dryers have gradually entered thousands of households, and intelligent clothes drying has become a major pursuit of people's lives. The future smart clothes dryer will become an important part of people's home life and occupy an important position in the future smart field. At present, there is no monitoring measure for the limit travel of intelligent clothes dryers on the market. During operation, micro switches are installed at the limit position, and the limit position is detected by touching the limit switch. Once the limit switch If it is damaged, the clothes dryer will keep running in the upward or downward direction without stopping until the load-bearing wire rope is broken. At the same time, because the clothes dryer is installed on the balcony,...

AI Technical Summary

Problems solved by technology

When the MCU controller receives the descending command from the remote control, it controls the bracket of the clothes dryer to move downward, and the pulley of the telescopic bracket moves in the direction of C. During the downward movement of the telescopic bracket 2, it touches the lower limit and moves slightly The arc-shaped pressure bar of the switch 7, at this time, the micro switch is changed from normally closed to normally open. After the MCU controller receives the action signal of the micro switch, it sends out an instruction signal prohibiting the downward operation of the clothes dryer, and the clothes dryer can stop. Downward operation, once the upper limit or lower limit micro switch fails or malfunctions, the clothes dryer will not stop according to the preset position, and will keep running up or down until the load-bearing connecting wire rope is broken or the device is damaged. There is a hidden danger of the telescopic bracket falling, which poses a certain threat to the personal safety of users

If you need to adjust the lower limit position of the lowest drop, you need to loosen the fixing screw of the lower limit micro switch, and move the lower limit micro switch to the left along the adjustment slot, but this operation can only be adjusted after the installation is completed, so the clothes dryer installation After the top of the balcony, the installer needs to adjust at high altitude, which is not good for the installer to adjust the lowest lower limit position, and because of the limited space of the structural parts, it is only limited to adjustment in the adjustment slot, which can only play a role in fine adjustment
