Abstract

The invention relates to the technical field of electromagnetic lock control, particularly provides an electromagnetic lock unlocking circuit and clothes processing equipment, and aims to solve the technical problem of how to unlock an electromagnetic lock locked on a door body in the clothes processing equipment under the condition that the clothes processing equipment or a power grid connected with the clothes processing equipment breaks down. In order to achieve the purpose, the unlocking circuit is provided with a switching power supply, a switch control circuit and a charging and discharging circuit, and when a control power supply of the electromagnetic lock is powered off, the switching power supply outputs electric energy to the electromagnetic lock control circuit through the switch control circuit, so that the electromagnetic lock control circuit unlocks the electromagnetic lock after being powered on; therefore, automatic unlocking of the electromagnetic lock is realized when the control power supply is switched off and the electromagnetic lock is in a locked state. Meanwhile, the switch control circuit can transmit the electric energy output by the switch power supply to the electromagnetic lock control circuit under the discharge control of the charge and discharge circuit, and the delay time for unlocking the electromagnetic lock is adjusted by adjusting the discharge time of the charge and discharge circuit.

Description

technical field [0001] The invention relates to the technical field of electromagnetic lock control, in particular to an electromagnetic lock unlocking circuit and a clothing processing device. Background technique [0002] Clothes processing equipment, such as washing machines, is usually provided with a door that can be opened / closed for placing clothes. Currently, a conventional door opening / closing method is to set an electromagnetic lock on the door, and the door can be opened by controlling the electromagnetic lock. / closure. Specifically, when the door needs to be closed, the laundry treatment device will send a lock control signal (such as a forward power signal) to the electromagnetic lock on the door, so that the electromagnetic lock can generate positive electromagnetic induction to achieve electromagnetic lock locking; When the door needs to be opened after the treatment, the laundry treatment device will send an unlocking signal (such as a reverse power signal)...
