Benefits of technology
The present invention provides an ice compartment that can be made at various depths and is smaller in size.
Problems solved by technology
However, in the case where the ice compartment is manufactured by injection molding, the per-unit cost of production using injection molding is comparatively high.
Therefore, there is a problem with conventional ice compartments due to higher production costs including the molding cost, the material cost, etc.
Thus, it is difficult to diversify the depths of ice compartments.
Therefore, the conventional technique cannot satisfy recent requirements for refrigerators having different sizes and shapes, for example, built-in refrigerators or counter-depth refrigerators, which are reduced in depth in order to fit with kitchen structures (e.g., relatively shallow cabinets) or other kitchen furniture.
In addition, another problem is that the volume of the ice compartment is increased because it is produced by assembling parts formed by injection molding.
Also, the appearance of the ice compartment is unattractive due to an inclined portion (draft angle) formed to enable a product to be easily separated from a mold during the injection molding process.

Embodiment Construction
[0019]Hereinafter, example embodiments of the present invention will be described in detail with reference to the accompanying drawings which form a part of the disclosure.
[0020]In describing the embodiments of the present invention, a detailed description of known functions or constructions related to the present invention will be omitted if it is deemed that such description would make the gist of the present invention unnecessarily vague.
[0021]FIG. 2A is a partial perspective view illustrating an ice compartment 210 in accordance with an example embodiment of the present invention. Unlike a conventional ice compartment manufactured by assembling a plurality of inner and outer housing plates with each other, the ice compartment 210 in accordance with the present example embodiment is integrally formed through a single extrusion molding process.
[0022]FIG. 2B is a cross-sectional view showing the ice compartment 210 that is manufactured by extrusion molding and is provided with a th...

A method for manufacturing a refrigerator includes providing a main body including a food storage space and a cold air generator, installing an ice compartment in the food storage space, the ice compartment being configured to produce ice, and installing a door on the main body, the door being configured to openably close the food storage space, wherein installing the ice compartment includes forming a housing of the ice compartment by extrusion molding, manufacturing a front end frame and a rear end frame which are respectively coupled to front and rear ends of the housing of the ice compartment, respectively coupling the front end frame and the rear end frame to the front and rear ends of the ice compartment, and performing a urethane foaming process to include thermal insulation in some of the space in the housing of the ice compartment.
Description
RELATED APPLICATION[0001]This application claims priority to Korean Patent Application No. 10-2015-0085877, filed Jun. 17, 2015, hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]Embodiments according to the present invention relate to a depth-adjustable ice compartment for a refrigerator and a method for manufacturing the ice compartment.BACKGROUND[0003]Generally, a refrigerator is an apparatus for low temperature storage of food and other items and may be configured to provide both freezing storage and cold storage of those items. For this, refrigerators include a cooling device or cold air generator. A cooling cycle is used in operating the cooling device or cold air generator.[0004]According to the cooling cycle, cold air is generated as refrigerant repeatedly circulates through the various stages of the cooling cycle including compression, condensation, expansion (decompression), and evaporation. The cold air supplied into the refrigerator is uniforml...
