The invention provides a power control device and a power control method of a disinfection cabinet and the disinfection cabinet. The power control device comprises a zero cross detection circuit, a control unit, and an actuator, wherein the zero cross detection circuit is used for detecting a ZCP (Zero Crossing Point) of an AC (alternating current) waveform, and generating a PWM (Pulse-Width Modulation) waveform according to the AC waveform; the control unit is connected with the zero cross detection circuit and is used for acquiring the ZCP waveform and the PWM waveform, adjusting the PWM waveform according to the ZCP of the AC waveform, and generating a PWM adjustment waveform; the control unit is further used for generating a control signal for controlling the actuator according to the PWM adjustment waveform; the actuator is used for connecting with the control unit, and controlling the heating power of the disinfection cabinet according to the control signal. The power control device and the power control method of the disinfection cabinet greatly reduce the interference of EMI (Electro-Magnetic Interference), enhance the stability of a circuit, and meet the demand of a product. A hardware circuit in the disinfection cabinet is simple, no additional electric part is added, and the effect of cost saving is achieved.
Description
technical field [0001] The invention relates to the technical field of disinfection equipment for tableware, in particular to a power control device and method for a disinfection cabinet and a disinfection cabinet. Background technique [0002] The safety and hygiene requirements for tableware disinfection cabinets (standard number: GB17988-2008) clearly stipulate the disinfection temperature and disinfection time of disinfection cabinets: the disinfection temperature in a one-star disinfection cabinet should be greater than or equal to 100 ° C, and the disinfection time should be greater than or equal to 15 minutes; The disinfection time in the two-star disinfection cabinet should be greater than or equal to 120°C, and the disinfection time should be greater than or equal to 20 minutes. [0003] Traditional disinfection cabinets use the following methods to control power to achieve the purpose of temperature control, so as to meet the requirements of national inspection sta...
