Auxiliary starting and energy circulating system for rotary type household appliance braking

The invention discloses an auxiliary starting and energy circulating system for rotary type household appliance braking and belongs to a brake energy circulating system. According to an auxiliary starting and energy circulating method for the rotary type household appliance braking, kinetic energy consumed during halt braking of a household appliance which performs rotation movement is effectively collected and stored inside an energy storage device through transmission speed change by utilizing a torque spring energy storage element and function conversion control, collected energy is released during restarting of the motor to assist the motor to start, and an energy consumption peak value during starting of the motor is reduced. The rotary type household appliance braking auxiliary starting energy circulating system comprises a transmission speed change module (A), a grading energy storage module (B) and a function switching module (C); the transmission speed change module is formed by a clutch, a transmission and a converter; the grading storage module is formed by a four-level energy storage torque spring and a ratchet-pawl mechanism in a matching mode; the function switching module is achieved through an electromagnetic controller. No multi-level energy is converted during an energy storage process, energy is stored for a short time and released timely, the released energy directly acts on a motor to assist starting, the motor starting energy consuming peak value is reduced, the motor energy consumption is effectively reduced, and motor model selection is optimized.
