Title:
CHARGER SEARCHING METHOD AND APPARATUS FOR UNDERWATER CLEANING DEVICE, AND UNDERWATER CLEANING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/174493
Kind Code:
A1
Abstract:
A charger searching method and apparatus for an underwater cleaning device (101), the underwater cleaning device (101), and a storage medium. Since an obstacle is provided between double closed electromagnetic loops formed by a wireless charger (102), there is a single closed electromagnetic loop in a swimming pool, the tangential position of the same magnetic induction line does not appear in the swimming pool, it is ensured that the underwater cleaning device (101) can accurately determine the position of the wireless charger (102) to move to a suitable wireless charging position, and the cleaning efficiency of the swimming pool is improved; moreover, the underwater cleaning device (101) is controlled to rotate and detect the magnetic flux of a first induction coil (1011) for the single closed electromagnetic loop, and if the magnetic flux is zero, it indicates that the wireless charger (102) is located in a direction orthogonal to the winding direction of the first induction coil (1011). Therefore, the orthogonal direction is used as the direction of travel, to ensure that the underwater cleaning device (101) is accurately moved to the wireless charger (102), thereby improving the accuracy of the charger searching position.
