6results about How to "Avoid frequent adjustments" patented technology

This invention relates to the field of household appliance technology, and discloses a control method and a garment processing device. The garment processing device has a display screen with an adjustable display position. The control method includes the following steps: detecting whether a user is moving within a preset area; when user movement is detected within the preset area, determining whether the user's movement target is the current garment processing device; if so, acquiring user information and controlling the display screen to adjust to a preset display position corresponding to the user information; if not, the display screen maintains its initial position. That is, when a user is present in the preset area, the display screen is only controlled to adjust its display position when the user's movement target is determined to be the current garment processing device. This prevents frequent adjustments to the display screen due to misjudgment, reducing the failure rate. Adjusting the display position according to user information allows the display screen to be positioned optimally for the user to view and operate, improving user convenience.
