JPH0560436A - Method for making clear square ice where air bubble remains at central part in freezing chamber of refrigerator for general home use - Google Patents

Abstract

PURPOSE:To manufacture square ice, put into a drink, as clear square ice where air bubbles remain at a central part by a method wherein water is poured in an ice making tray, which is covered with an upper cover to close in a state that a little air enters an upper part, the ice making tray is fixed by means of the fixing metal of an ice making chamber, and temperature is reduced to an ice making temperature as the upper and lower parts thereof are rotated at low rotation with the aid of a small motor. CONSTITUTION:Water is poured in an ice making tray 11 and covered with an upper cover 10 to close in a state that a little air remains at an upper part. An ice making chamber 5 of a refrigerator is provided with lower and upper fixing metals 3 and 4 to securely nip the ice making tray 11 therebetween. The upper and lower fixing metals 3 and 4 are mounted on the deep surface of the ice making chamber 5 so that the fixed ice making tray 11 is rotated in a manner to cause the upper and lower parts to draw a circle, as seen from the door side of the ice making chamber 5, and rotated at a low speed with the aid of a small motor 6 for low speed rotation in a state that the ice making tray 11 is left fixed. The temperature of the ice making chamber 5 is reduced to freeze water as the ice making tray 11 is rotated at a low speed. This method causes air to remain as air bubbles at the central part of square ice.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a method for producing ice cubes to be put into a drink as transparent ice cubes having bubbles in the center thereof.

[0002]

2. Description of the Related Art Conventionally, ice cubes are opaque or transparent ices and are only in the shape of a prism.

[0003]

[Problems to be Solved by the Invention] The ice cubes to be put into drinks produced so far are opaque or transparent ice cubes.
It didn't change for a long time, and I wasn't satisfied with transparent and fashionable cups and glasses. The present invention solves the above drawbacks,
The ice cubes are used to make the drink taste more visually appealing.

[0004]

[Means for Solving the Problems] Water is put in an ice tray, and the upper lid is sealed so that a little air is contained in the ice tray, and the ice tray is sealed. This is a method of producing ice cubes by fixing it with the fixing metal fittings of the ice making chamber and rotating it up and down at a low speed with a small motor to reach the ice making temperature.

[0005]

[Function] The ice tray with the top lid filled with water is rotated up and down at a low speed to reach the ice making temperature. Therefore, the water contained in the ice tray comes from the area where the ice tray and the top lid are in contact with each other. The air left at the end is left round in the center because it freezes to the center. In addition, since the ice tray is rotating up and down at a low speed, the water inside also freezes while moving, so that the ice can be made transparent. Therefore, a transparent ice cube with round bubbles is formed in the center.

[0006]

[Example] Put water in an ice tray such as polyethylene,
Cover with a top lid so that the top is slightly airy. In order to fix the ice tray by sandwiching it in the ice-making room of the refrigerator, make a lower fixing bracket and an upper fixing bracket. The upper and lower fixing brackets are attached to the inner surface of the ice making chamber so that the fixed ice tray rotates in a circle when viewed from the door side of the ice making chamber.
Keep the ice tray fixed and rotate at low speed. While rotating the ice tray at a low speed, lower the temperature of the ice making chamber to freeze the water. Remove the ice tray from the ice making chamber, remove the top lid,
Twist the ice tray to obtain ice cubes. In the process of freezing water,
Since the ice tray is rotated at low speed, the water freezes as it moves, so clear ice forms. Also, as air bubbles,
Since it remains in the center of the ice cube, ice can be seen in the center of the transparent ice cube through the rounded edges of the bubbles. The above is the first plan. As a second plan, a magnet is embedded in the bottom part of the polyethylene ice tray, water is put in the ice tray, a little air is put in and the upper lid is fixed with magnetic force to the lower fixing bracket, It is possible to make transparent ice cubes containing air bubbles by applying the above-described low-speed rotation motion to the ice tray.

[0007]

[Effects of the Invention] This transparent ice cube with a round edging in the center is put in a transparent and fashionable cup or glass, and when a drink with a transparency is put, there is a feeling of transparency, and a quadrangle and a circular edging are obtained. , Diffusely reflected by the light rays, mysterious, very beautiful, giving the drink a visually chilly, transparent taste. In addition, by integrating the lower fixing bracket and the ice tray, the upper fixing bracket and the upper lid, etc., with the transparent ice cube manufacturing method with bubbles as described above,
Can build a commercial ice cube maker.

Claims (1)

[Claims] 1. An ice tray is filled with water, and the upper lid is sealed so that a little air is contained in the upper portion. The ice cube tray is fixed with the metal fittings in the ice making chamber, and while keeping it fixed, the top and bottom are rotated at low speed to make ice cubes to produce ice cubes. It is a manufacturing method.
