Description

Technical Field

[0001] This invention relates to the field of washing machine power technology, specifically a portable washing machine power energy-saving control system. Background Technology

[0002] Portable washing machines are small, lightweight, and easy-to-carry laundry appliances. To facilitate portability and temporary use in areas without mains power, some portable washing machines have built-in lithium batteries. This allows the machine to be powered by mains power when available and by the built-in lithium battery when no mains power is available. However, these machines cannot automatically switch power modes based on the battery's charge level and the mains power supply status. This can easily increase electricity costs when using mains power for extended periods and also fails to make efficient use of the regenerative energy generated during washing machine operation, resulting in energy waste. Therefore, improvements are needed. Summary of the Invention

[0030] In a specific embodiment, the second comparator A2 can be an LM358 comparator; the second reference power supply VF2 can be set with a full-charge threshold.

[0031] The working principle of the portable washing machine power energy-saving control system of the present invention is as follows: The power processing device performs voltage reduction and rectification filtering on the mains power. A voltage divider is formed by the first resistor R1 and the second resistor R2, providing a first detection signal to the IO8 terminal of the first controller U1. The energy storage device performs voltage divider by the third resistor R3 and the fourth resistor R4. When the sampled signal is lower than the full-charge threshold set by the second reference power supply VF2, the second comparator A2 outputs a low level. At this time, power is supplied only through the power processing device. The IO2 terminal of the first controller U1 controls the second power transistor Q2 to always be on, and controls the conduction state of the first power transistor Q1 through the IO1 terminal. When the first power transistor Q1 is on, the first inductor L1 stores energy, and the second capacitor C2 and the third... Diode D3, third capacitor C3, first power transistor Q1, and second power transistor Q2 form a circuit, which charges third capacitor C3. If charging control of the energy storage device is required at this time, the IO5 terminal of the first controller U1 will control the third thyristor S3 and the sixth thyristor S6 to conduct, so that the fourth capacitor C4, through the third thyristor S3 and the second power transistor Q2, is connected in parallel with the fifth capacitor C5 to supply power to the energy storage device. When the first power transistor Q1 is off, the first inductor L1 discharges and is connected in series with the first power output from the power processing device, and then charges the second capacitor C2 through the second diode D2 and the second power transistor Q2. At the same time, the power processing device is connected in series with the first inductor L1 and the third capacitor C3, and through the fourth diode D4 and the second power transistor Q2... The fourth capacitor C4 is charged, thereby completing single-channel power regulation and voltage multiplication. If the energy storage device is not powered at this time, the first inverter T1 needs to be powered. The IO4 terminal of the first controller U1 will control the second thyristor S2 and the fifth thyristor S5 to conduct, thereby making the fourth capacitor C4 and the sixth capacitor C6 connected in parallel to power the first inverter T1. The IO7 terminal of the first controller U1 drives the first inverter T1 to perform inverter and frequency conversion work through four sets of pulse signals, thereby driving the washing machine motor to work. During the power supply to the first inverter T1, if the power processing device is de-energized and the energy storage device's charge is not lower than the low charge threshold, the first controller U1 will continuously control the first power transistor Q1 to conduct and control the conduction state of the second power transistor Q2. When the second power transistor Q2 is turned on, the second inductor L2 stores energy. The third capacitor C3 charges the fourth capacitor C4 through the fourth diode D4, the first power transistor Q1, and the second power transistor Q2. When the second power transistor Q2 is turned off, the second inductor L2 is connected in series with the energy storage device and charges the third capacitor C3 through the fifth diode D5 and the first power transistor Q1. Simultaneously, it is connected in series with the fourth capacitor C4 and supplies power to the first frequency converter T1 through the second thyristor S2. If the power processing device supplies power and the energy storage device is fully charged, the second comparator A2 will output a third detection signal, which is received by the IO10 terminal of the first controller U1. The first controller U1 can control the first power transistor Q1 and the second power transistor Q2 to conduct alternately with a phase difference of 180 degrees. Specifically, the control is as follows:When both the first power transistor Q1 and the second power transistor Q2 are on, the first inductor L1 and the second inductor L2 store energy, which powers the first inverter T1 via the sixth capacitor C6. When the second power transistor Q2 is on and the first power transistor Q1 is off, the second inductor L2 stores energy, the first inductor L1 discharges, and charges the second capacitor C2 and the fourth capacitor C4 through the transmission path. When the second power transistor Q2 is off and the first power transistor Q1 is on, the first inductor L1 stores energy, and the energy storage device is connected in series with the second inductor L2 and the fourth capacitor C4 and powered by the second thyristor S2. The sixth capacitor C6 and the first frequency converter T1 are powered. At this time, the power demand of the power processing device can be reduced, and the power supply can be mixed with the energy storage device to reduce the power cost. If the power processing device is de-energized and the energy storage device is below the low power threshold, the first comparator A1 outputs the second detection signal, which is received by the IO9 terminal of the first controller U1. The IO6 terminal of the first controller U1 will control the fourth thyristor S4, the fifth thyristor S5, and the second thyristor S2 to conduct. The first controller U1 controls the first power transistor Q1 and the second power transistor Q2 to switch on. When the power supply is switched on, the energy storage device simultaneously powers the first inductor L1 and the second inductor L2, performing dual-path power regulation, voltage superposition, and voltage multiplication to maintain power supply to the first inverter T1. When the washing machine motor brakes, the first inverter T1 stops working, and the electrical energy generated by the washing machine motor is rectified by the first inverter T1 to output regenerated electrical energy. When the power processing device is powered, the first controller U1 simultaneously controls the sixth thyristor S6 and the third thyristor S3 to conduct, controlling the first power transistor Q1 and the second power transistor Q2 to conduct alternately, thereby enabling the direct current to... The DC-DC converter module 3 performs dual-path regulation, voltage superposition, and voltage multiplication on the regenerated and primary electrical energy, and supplies power to the energy storage device. If the power processing device is without power, the IO3 terminal of the first controller U1 will control the first thyristor S1, the sixth thyristor S6, and the third thyristor S3 to conduct. The first controller U1 also controls the first power transistor Q1 and the second power transistor Q2 to conduct alternately. The DC-DC converter module 3 will then perform dual-path regulation, voltage superposition, and voltage multiplication on the regenerated electrical energy and supply power to the energy storage device, automatically switching the power supply mode to improve power supply efficiency and energy saving.
