Title:
CONTROL METHOD OF ICE MAKER
Document Type and Number:
WIPO Patent Application WO/2019/114665
Kind Code:
A1
Abstract:
A control method of an ice maker. The ice maker (1) comprises: an ice storage container (10), an ice feeding device (20) located at a bottom portion of the ice storage container (10) and capable of being rotated, and a detection device (30) for detecting a full-of-ice state of the ice storage container (10). The control method comprises: each time after sequentially completing an ice making operation and a defrosting operation, performing full-of-ice detection to detect whether the ice storage container (10) is in the full-of-ice state; performing the ice making operation and the defrosting operation when it is determined by means of full-of-ice detection that the ice storage container (10) is not in the full-of-ice state; driving the ice feeding device (20) to rotate, so as to perform a full-of-ice correction when it is determined by means of the full-of-ice detection that the ice storage container (10) is in the full-of-ice state, and recording the number of full-of-ice corrections after completing the full-of-ice correction; and performing, after each full-of-ice correction, correction detection to detect whether the ice storage container (10) is still in the full-of-ice state. The invention corrects a full-of-ice state detection result, thereby avoiding an issue in which the ice storage container is falsely determined to be in the full-of-ice state before the ice storage container has been fully filled due to the ice not accumulating horizontally.
