Ice making method for refrigerator and refrigerator

A refrigerator, comprising an ice making compartment with an ice making container inside, wherein the refrigerator further comprises:

• a chamber heating unit, configured to raise the temperature inside the ice making compartment to or above a first preset value before supplying water to the ice making container;
• a water heating unit, configured to raise the temperature of the water entering the ice making container to or above a second preset value;
• and
• a refrigeration device, configured to provide cold energy to the ice making compartment according to the first refrigeration capacity, sequentially lowering the temperature inside the ice making compartment to multiple first preset temperatures, and when the temperature inside the ice making compartment decreases to each first preset temperature, maintaining the temperature at that first preset temperature for the corresponding first preset duration;
• among two adjacent first preset temperatures, the first preset duration corresponding to the lower first preset temperature being shorter than that for the higher first preset temperature;
• and after providing cold energy according to the first refrigeration capacity, providing cold energy according to the second refrigeration capacity, sequentially lowering the temperature inside the ice making compartment to multiple third preset temperatures, and when the temperature inside the ice making compartment decreases to each third preset temperature, maintaining the temperature at that third preset temperature for the corresponding third preset duration;
• among two adjacent third preset temperatures, the third preset duration corresponding to the lower third preset temperature being shorter than that for the higher third preset temperature;
• with the second refrigeration capacity being greater than the first refrigeration capacity.
