Laundry processing apparatus

摘要

The present invention provides a laundry processing apparatus (100), which includes: a laundry processing drum (22), used for holding laundry for processing; a driving system (30), used for driving the laundry processing drum (22) to process the held laundry; and a power control system (10), at least used for providing power of a grid for the driving system (30), where the power control system (10) includes an electrical storage device (11). Through the setting, when external grid power outage occur or the fluctuation of the voltage is excessively large, the power control system may switch a power storage device to supply power to the laundry processing apparatus, thereby eliminating the influence on the apparatus caused by unstable voltage of power transmitted by the grid or grid power outage, and avoiding the trouble brought to a user.

主权项

1. A laundry processing apparatus, comprising:
a laundry processing drum configured to hold laundry for processing; a driving system, configured to drive the laundry processing drum to process the held laundry; and a power control system, at least configured to provide power of a power grid for the driving system, wherein the power control system further comprises an electrical storage device configured to provide power for the driving system;wherein:
the power control system further comprises: (a) a charger electrically connected to the electrical storage device and configured to convert alternating current supplied via the power grid into direct current to charge the electrical storage device, (b) an inverter electrically connected between the electrical storage device and the driving system and configured to convert the direct current from the electrical storage device into an alternating current; and (c) a first switch to electrically connect (i) between the grid and the driving system in a first condition when input voltage from the grid is within a predetermined range, and (ii) between the electrical storage device and the driving system in a second condition when the input voltage is not within the predetermined range such that the electrical storage device provides voltage to the driving system sufficient to rotate the laundry processing drum.
