Problems solved by technology

However, this direct touch-and-press closing method is easy to cause deformation of the bracket and the micro switch, and even more seriously, it will cause damage to the micro switch, and the damage of the micro switch will cause the clothes dryer to continue to rise. Or drop until the wire rope is broken and the product can no longer be used normally

Embodiment 1

[0042] When the motor controls the telescopic bracket 2 to move from the lower limit position to the upper limit position, the permanent magnet 3 moves towards the direction close to the magnetic induction limit module in the movable slot 101 along with the upper movable end 201 of the telescopic bracket 2 at the same time, as image 3 As shown, when the telescopic bracket 2 moves to the upper limit position, the distance between the permanent magnet 3 on the upper movable end 201 and the magnetic induction limiting module 4 reaches the minimum value, and the magnetic induction limiting module 4 receives the signal from the permanent magnet 3 Maximum magnetic field strength value H max And get the corresponding analog signal, further send out the pulse signal to change the maximum magnetic field strength value H max Send to the MCU controller, and the MCU controller receives the maximum magnetic field strength value H max , and further set the maximum magnetic field strength va...

Embodiment 2

[0044] This embodiment is the same as Embodiment 1, except that the operation sequence is just reversed.

[0045] The motor controls the telescopic bracket 2 to move from the upper limit position to the lower limit position, and at the same time the permanent magnet 3 moves in the movable groove 101 along with the upper movable end 201 of the telescopic bracket 2 in a direction away from the magnetic induction limiting module 4, as Figure 4 As shown, when the telescopic bracket 2 moves to the lower limit position, the distance between the permanent magnet 3 on the upper movable end 201 and the magnetic induction limiting module 4 reaches the maximum value, and the magnetic induction limiting module 4 receives the signal from the permanent magnet 3 Minimum magnetic field strength value H min And get the corresponding analog signal, further send out the pulse signal to set the minimum magnetic field strength value H min Send to the MCU controller, and the MCU controller receiv...

Abstract

The invention discloses an electromagnetic induction device used for an electric clothes drying machine and an operation method of the electromagnetic induction device. The electromagnetic induction device comprises a permanent magnet and a magnetic induction limit module, the permanent magnet is fixedly or movably installed on the outer side wall of the upper movable end of a retractable bearingframe of the electric clothes drying machine and used for generating a magnet field, and the magnetic induction limit module is arranged on a panel of a main electric clothes drying machine body; a signal output port of the magnetic induction limit module is electrically connected with a signal input port of an intelligent controller of the electric clothes drying machine, the permanent magnet canmove along with ascending and descending of the retractable bearing frame, so that the intensity of the magnetic field acting on the magnetic induction limit module is changed, and the magnetic induction limit module senses and obtains a changed magnetic field intensity value and outputs an instant magnetic field intensity value signal to the intelligent controller in real time. The device can effectively solve the problem that according to a traditional product, a touch switch is touched and pressed for a long time and damaged, and achieve the effect of prolonging the service life of the clothes drying machine, and the device adopting the structure and the operation method has good market competitiveness and attraction.

Description

technical field [0001] The invention relates to the technical field of electric clothes dryers, in particular to an electromagnetic induction device used on an electric clothes dryer and an operating method thereof. Background technique [0002] At present, the electric clothes dryers on the market mainly use micro switches to realize the limit stop during the up and down movement. The micro switch is generally installed on the left and right sides of the main body of the clothes dryer. When the clothes dryer rises or falls to the limit position, rely on the bracket to touch the micro switch to turn off the motor to ensure that the clothes dryer is rising or falling. After falling to the limit position, it will no longer move. However, this direct touch-and-press closing method is easy to cause deformation of the bracket and the micro switch, and even more seriously, it will cause damage to the micro switch, and the damage of the micro switch will cause the clothes dryer to...
