AI Technical Summary

Problems solved by technology

Since the mold for die-casting is severely worn at the melting temperature of aluminum (about 600°C) during molding, the durability of the mold is short
In addition, since the tank 2 and the mounting part 5 are molded integrally, even if the size of the ice is the same, a new mold must be made every time the mounting part 5 is changed in order to meet the customer's needs.
And, because the shape of groove 2 is determined by mould, therefore, just must make new mould, if will make the ice of different size

Embodiment Construction

[0020] Fig. 1A is a perspective view of ice tray device 11 according to the embodiment of the present invention. FIG. 1B is a schematic diagram of refrigerator 1002 including ice tray 11 . Ice tray unit 11 is configured to be used in refrigerator 1002 and is arranged in freezer compartment 1003 of refrigerator 1002 . The ice tray unit 11 includes two mounting portions 24 and a metal tray 31 . The disk 31 is a separate body from the mounting portion 24 .

[0021] The disk 31 is composed of a box-shaped portion 22 having seven grooves 21A, 21B, and six partition plates 23 connectable to the box-shaped portion 22 . The tanks 21A, 21B of the box-shaped portion 22 are configured to store water, and have a bottom 22A in the shape of a semi-cylindrical surface. The partition plate 23 is a separate member from the box-shaped portion 22 . Notches 23A are formed on the partition plate 23 through which water can enter and exit the seven grooves 21A, 21B mutually. The box-shaped part...

Abstract

An ice tray unit is configured to be used in a refrigerator. The ice tray unit includes a mounting section configured to be mounted to the refrigerator, and a tray coupled to the mounting section. The tray is made of metal. The tray includes a box section configured to pool water, and partition plates coupled with the box section. The tray is independent from the mounting section. The partition plates are independent from the box section. The ice tray unit provides a die for manufacturing it with a large durability.

Description

technical field [0001] The present invention relates to an ice tray device provided in a freezer compartment of a refrigerator such as a freezer refrigerator and having an ice tray for generating ice, and a method for manufacturing the same. Background technique [0002] Fig. 7 is a perspective view of a conventional ice tray 1 disclosed in Japanese Patent Laid-Open No. 2001-272146. FIG. 8 is a cross-sectional view of the ice tray 1 shown in FIG. 7 along line 8-8. Ice tray 1 is formed by die-casting aluminum alloy, which is a metal with high thermal conductivity. Ice tray 1 is arranged in a freezer compartment of a freezer-refrigerator. The ice tray 1 includes a plurality of tanks 2 for temporarily storing water, and an attachment portion 5 integrally formed with the tanks 2 . The mounting part 5 is fixed to the wall surface of the refrigerator with screws. Furthermore, adjacent grooves 2 are connected to each other by recesses 3 . [0003] As shown in FIG. 8 , the heat...
