A dishwasher and a control method thereof

Abstract

The invention belongs to the technical field of dishwashers, in particular to a dishwasher and a control method thereof. The aforementioned dishwasher includes a housing, and a plasma sterilizing anddisinfecting device arranged in the shell, the plasma sterilization and disinfection device comprises a plurality of discharge electrode plates and a plurality of grounding electrode plates, an RF power supply and a grounding power supply, the discharge electrode plates and the ground electrodes plate are spaced apart, a tableware storage space is for between that discharge electrode plate and theground electrode plate, the radio frequency power supply is connected with the discharge electrode plate, and the grounding power supply is connected with the grounding electrode plate. Through reasonable design of the discharge electrode structure, the dishwasher generates glow plasma covering tableware in large area, utilizes the plasma to sterilize tableware efficiently, solves the problems oflow efficiency and long processing time faced by the existing dishwasher sterilization method, thereby reducing sterilization time of the dishwasher and improving sterilization effect of the dishwasher.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, and in particular relates to a dishwasher and a control method thereof. Background technique [0002] With the improvement of the ability to remove oil stains, dishwashers are more and more recognized by consumers, and the related market is also growing, and there is a tendency to replace household disinfection cabinets, which requires dishwashers to be efficient, fast, and broad-spectrum. Sterilization characteristics. At present, dishwashers often use hot water sterilization or high temperature and high pressure sterilization, but hot water sterilization cannot effectively remove the bacterial content in dishwashers, and high temperature and high pressure sterilization has poor stability and is difficult to control. However, plasma sterilization has the following characteristics: (1) It has broad-spectrum antibacterial properties, and it generally only takes a few minutes to reach the leve...
