Ice-making device and method for refrigerator

Abstract

The invention provides an ice-making device and method for a refrigerator. The ice-making device comprises an ice-making mould arranged in a first refrigeration room with the temperature being lower than 0 DEG C and provided with a plurality of ice-making cavities, a water storage device filled with high-pressure water, a water feeding pipe communicating with the water storage device and the ice-making cavities, a valve and a controller, wherein the valve and the controller are arranged on the water feeding pipe and are in communication connection; the water storage device is arranged in a second refrigeration room with the temperature being higher than 0 DEG C; on the one hand, in the process that supercooled water enters the ice-making cavities from the water feeding pipe, the phenomenon of ice plugging of the supercooled water in the water feeding pipe can be prevented; on the other hand, after the supercooled water flows out of the water storage device, the pressure intensity of the supercooled water is relieved, and the freezing point is raised, so that the supercooled water is quickly solidified into ice after entering the ice-making cavities, and the ice-making speed is increased; and meanwhile the ice-making cavities are in a closed state, the phenomenon of taint of odor of the supercooled water can be prevented, and the quality of a made ice block is improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to an ice-making device and an ice-making method for a refrigerator capable of rapidly making ice. Background technique [0002] With the continuous acceleration of people's life rhythm and the continuous development of refrigerator technology, large-volume, multi-functional refrigerators have become more and more popular among consumers. The automatic ice-making function is undoubtedly a must-have function for high-end refrigerators. [0003] Existing refrigerators are generally equipped with ice-making boxes with multiple ice-making boxes. The ice-making boxes are automatically filled with water through manual or water pumps, and the ice-making boxes are placed in a refrigerated room with a temperature below 0°C. Relying on the cooling capacity of the refrigerator to freeze the water in the ice-making box into multiple ice cubes, however, this ice-making method takes a long...

Problems solved by technology

[0003] Existing refrigerators are generally equipped with ice-making boxes with multiple ice-making boxes. The ice-making boxes are automatically filled with water through manual or water pumps, and the ice-making boxes are placed in a refrigerated room with a temperature below 0°C. Relying on the cooling capacity of the refrigerator to freeze the water in the ice-making box into multiple ice cubes, however, this ice-making method takes a long time to make ice, and the water in the ice-making box is exposed to the air for a long time, which will easily lead to odors , resulting in unclean ice cubes
