Title:
REFRIGERATOR AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/005086
Kind Code:
A1
Abstract:
A refrigerator comprises a box body, an ice maker, a water injection pipe, a heating apparatus, a flow detection apparatus, a water pressure detection apparatus, and a controller. The flow detection apparatus is configured to detect the water flow at a water outlet of the water injection pipe and output a flow signal. The water pressure detection apparatus is configured to detect the water pressure at a water inlet of the water injection pipe and output a water pressure signal. The controller is configured to: receive the water pressure signal and the flow signal; when a heating condition of the water injection pipe is met, determine a current icing area at the water outlet of the water injection pipe on the basis of a numerical value corresponding to the water pressure signal, a numerical value corresponding to the flow signal, and a first mapping relationship; determine a current icing time on the basis of the current icing area and a second mapping relationship; and control the heating apparatus to heat on the basis of the current icing time.
