By adopting the household electrical appliance provided by the embodiment of the disclosure, the power switch 2 can be closed and conducted under the condition that the power switch is pressed by an adult user, so that the control module 5 obtains power supply, and the control module 5 controls the magnetic action 6 module to generate magnetic force so as to enable the protection switch 3 to be closed and conducted. In case of a child's misuse of the power switch, such that the power switch 2 is turned from closed on to open, the control module 5 is maintained powered as the protection switch 3 is still in the closed on state. And as the control module 5 still maintains power supply, the magnetic action module 6 is controlled to maintain magnetic force, so that the protection switch 3 is kept closed and conducted continuously, and the control module 5 still maintains power supply. Therefore, when the power key of the household electrical appliance is touched by a child by mistake, the household electrical appliance is prevented from being powered off, and the working procedure of the household electrical appliance is prevented from being interrupted. Meanwhile, if the protection switch 3 is in a closed state under an emergency, the household electrical appliance is required to stop working, and under the condition that the socket is inconvenient to pull out, the protection switch 3 is better opened, so that the household electrical appliance is better powered off.
Alternatively, the protection switch 3 is opened in case the magnetic force acting in the first direction is smaller than a preset threshold, including that the protection switch 3 is deactivated in the first direction. Specifically, in the case where the unlocking switch 15 is turned off by an external force, the magnetic force in the first direction of the protection switch 3 is lost. Therefore, when the power key of the household electrical appliance is touched by a child by mistake, the household electrical appliance is prevented from being powered off, and the working procedure of the household electrical appliance is prevented from being interrupted. Meanwhile, if the protection switch is in a closed state under an emergency, the household electrical appliance is required to stop working, and under the condition that the socket is inconvenient to pull out, the protection switch 3 is better disconnected, so that the household electrical appliance is better powered off.
Alternatively, the unlocking switch 15 includes an electromagnetic relay, or a knife switch. Therefore, when the power key of the household electrical appliance is touched by a child by mistake, the household electrical appliance is prevented from being powered off, and the working procedure of the household electrical appliance is prevented from being interrupted. Meanwhile, if the protection switch is in a closed state under an emergency, the household electrical appliance is required to stop working, and under the condition that the socket is inconvenient to pull out, the protection switch 3 is better disconnected, so that the household electrical appliance is better powered off.
Optionally, the home device further comprises a housing 12. The housing 12 is provided with a switch groove and a shutter, and the unlocking switch 15 is provided in the switch groove and covered with the shutter. Thus, since the unlocking switch 15 is hidden by the shutter, it is not easily perceived by children. Under the condition that the power key of the household electrical appliance is touched by children by mistake, the household electrical appliance is prevented from being powered off, and the working procedure of the household electrical appliance is prevented from being interrupted. It is advantageous to better open the protection switch 3, so that the household appliance is better powered off. Meanwhile, the power-off of the household appliance caused by the fact that the child touches the unlocking switch 5 by mistake is avoided.
Optionally, the home appliance comprises a washer, dryer or oven. Therefore, the washing machine, the clothes dryer or the oven is easy to be pressed by children in disorder during working, so that various household appliances can be protected. Under the condition that the power key of the household electrical appliance is touched by children by mistake, the household electrical appliance is prevented from being powered off, and the working procedure of the household electrical appliance is prevented from being interrupted.
