BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a clear ice cube tray which generates clear ice cubes without bubbles formed therein.

2. The Prior Arts

A conventional way for making ice cubes generally includes bubbles formed in the ice cubes, and because the reflection feature of the bubbles is different from the transparent ice cube, the ice cubes with bubbles appear white and not transparent.

The common ice cube trays cannot remove the bubbles from the ice cubes so that the ice cubes made at home are not transparent.

There is an ice cube maker that is integrated with specially designed refrigerator that is able to make clear ice cubes. However, the method is to freeze water drops to become the clear ice cubes and can only be used within special refrigerators. The ice cube maker is so costly that it is not practical for common users. The ice cube maker cannot be used with the general refrigerator designed for home use. Furthermore, the ice cube maker that is able to make small, uni-size clear ice cube cannot make ice cubes of large volume and special shapes.

The present invention provides a clear ice cube tray that is able to make clear ice cube in different sizes at low cost, which improves the shortcomings of the conventional ice cube maker.

SUMMARY OF THE INVENTION

A primary objective of the present invention is to provide a clear ice cube tray that is cooperated with general refrigerator and able to make clear ice cubes at lower cost.

Another objective of the present invention is to provide a clear ice cube tray that is able to make ice cubes of different sizes and shapes suitable for commercial use.

According to the present invention, a clear ice cube tray is provided and comprises an inner box having a plurality of holes formed through a bottom thereof, and an outer box has an open top through which the inner box is received. The shape of inner and outer boxes is congruent. The outside of the inner box is air-tightly contacted with the inside of the outer box. A gap is defined between the bottom of the inner box and the inner end of the outer box. A heat isolation housing has a space in which the outer box is accommodated. The outside and the bottom of the outer box are tightly contacted with the inside and an inner end of the heat isolation housing.
