The invention belongs to the field of power supply drive for dishwashers, and provides a dishwasher and its backup power supply system and method. The invention adopts a backup power supply system including a power selection conversion module and a storage battery in the dishwasher. When there is no alternating current or direct current in the power supply line of the dishwasher, the power selection conversion module directly outputs the direct current output from the storage battery to the main control unit. board or convert the direct current output from the battery into alternating current and then output it to the main control board, and then drive the main control board to control the corresponding load in the dishwasher according to different washing programs, so that the dishwasher can operate when the power supply is stopped. Work as usual. In addition, the present invention also adds a battery charging module in the backup power supply system, and the battery charging module detects the power of the battery in real time when the power supply is normal, and charges the battery when the power of the battery is insufficient, so that the battery can maintain sufficient power. state, providing protection for the backup power supply of the dishwasher.
Description
technical field [0001] The invention belongs to the field of power supply drive for dishwashers, in particular to a dishwasher and its backup power supply system and method. Background technique [0002] Currently, existing dishwashers are widely driven by external power sources. Such a power supply drive system has a simple structure and is easy to implement, but it requires the power system to be able to provide a stable power supply. However, for some areas where the power system is not stable enough, power outages are more frequent, which will cause the dishwasher to fail to work, which will affect the normal use of the dishwasher and bring a lot of inconvenience to users. Promoting the application of dishwashers brings great difficulties and obstacles. Therefore, for the existing dishwasher, it has the problem of being unable to work due to power failure. Contents of the invention [0003] The object of the present invention is to provide a backup power supply syste...
