Abstract

The invention provides a refrigerator, by which we can get very transparent ice in rough rectangle with low-cost structure. The refrigerator (1) comprises a main refrigerator body (21) shaping a storeroom, a freezing circle of a cooler (64) used for cooling the storeroom, a ice-making device in the refrigerator body (21) and controlling equipment. Ice-making device comprises a condenser (67) for ice-making, having a slice of component of the freezing circle, a ice-making part (68) of the declining ice-making surface (31a), a water cycling device sending the water used for making ice to ice-making surface (31a) of the ice-making part (68), a heater (72) used for peeling the wattle ice off from the ice-making surface (31a) of the ice-making part (68), a ice intersected device used for dividing the wattle ice (35) peeled from the ice-making surface (31a) of the ice-making part (68) into rough rectangular, and a container (57) used for keeping the ice created in the ice-making part (68).

Description

technical field [0001] The present invention relates to a refrigerator, in particular to a household refrigerator equipped with an ice making device for generating transparent ice. Background technique [0002] In recent years, household refrigerators on the market tend to increase in capacity in view of changes in eating habits and food distribution. During this change, users' expectations for ice became higher, and refrigerators (Prior Art 1) incorporating an ice making device provided with a dedicated ice making compartment with an independent door, and An ice making tray is provided in the ice making chamber. [0003] In the ice making device of the prior art 1, a water storage tank is provided in the refrigerator compartment, and an ice making tray as an ice making part is installed in the ice making room, and an appropriate amount of water in the water storage tank is supplied to the ice making tray by a pump. The cold air supplied to the ice making chamber freezes t...
