The invention discloses a protection and control device for a household electrical appliance. The protection and control device comprises a control part and a first load loop. The control part comprises a processing chip, a driving part and a protection and control circuit. The processing chip is connected with the protection and control circuit and the driving part. The processing chip is used for outputting a protection and control signal and a driving signal. The protection and control signal has a first state and a second state. The driving part is used for driving the first load loop to work according to the driving signal. The protection and control circuit is used for controlling connection of the first load loop according to the protection and control signal of the first state and also used for controlling disconnection of the first load loop according to the protection and control signal of the second state. According to the protection and control device of the household electrical appliance, the protection and control circuit can control the load loop to be disconnected when the state of the protection and control signal is the second state and the load is enabled to stop working so that safety of the load can be guaranteed and the resulting safety risk can be solved. The invention also discloses the household electrical appliance.
Description
technical field [0001] The invention relates to the field of household appliances, and more specifically, to a protection control device for household appliances and the household appliance. Background technique [0002] With the deepening of the diversity of household appliances, their safety protection performance has gained more attention, especially fire safety. In the design of household appliances, fire protection requirements such as electrical clearances and creepage distances need to be considered. However, in related technologies, there is no corresponding protection for the main control chip of household appliances when an unknown out-of-control occurs, so as to prevent The load continues to work uncontrolled, resulting in danger. Contents of the invention [0003] The embodiments of the present invention aim to solve at least one of the technical problems in the prior art. Therefore, the embodiment of the present invention needs to provide a protection contro...
