Abstract

The invention relates to a power-failure processing circuit of a dishwasher and a control method thereof. The power-failure processing circuit comprises a data storage device and an input power supply, wherein the data storage device is used for storing washing state parameters of the dishwasher, and the input power supply provides direct-current working voltage for the data storage device and the following circuits and devices. The power-failure processing circuit is characterized by also comprising a main controller and a connecting circuit, wherein the main controller is electrically connected with the data storage device through the connecting circuit, so that when the dishwasher is powered on, the main controller can read the washing state parameters from the data storage device and judge whether the washing state before power failure is needed to be restored or not, and can write the washing state parameters into the data storage device during washing of the dishwasher, and signals processed by the main controller are output to a load execution unit. The power-failure processing circuit of the dishwasher has the advantages of simple structure, low hardware cost, capability of shortening the washing time, energy conservation and the like.

Description

technical field

[0001] The invention belongs to the field of dishwasher control, in particular to a dishwasher power-off processing circuit and a control method, and belongs to the improvement technology of dishwasher power-off processing control. Background technique

[0002] For abnormal power-off events during the washing process, the dishwasher adopts corresponding processing and control methods, so that the dishwasher can continue the washing process after being powered on again, and meet the cleaning performance requirements. This treatment method is a reflection of the dishwasher in terms of washing energy efficiency, machine intelligence and user satisfaction;

[0003] Currently, the washing process of a dishwasher can generally be divided into four stages: a pre-washing stage, a main washing stage, a rinsing stage, and a drying stage. For existing dishwashers, for abnormal power-off events during the washing process, the usual practice is to start washing from the ...
