Benefits of technology

[0017] The mixing device may further include a fan rotated in the mixing room to accelerate the mixing of the chilled air.
[0024] The mixing room and the supercooling compartment may further include insulators for preventing temperature variation affects due to the temperature of the refrigerator compartment and of the freezer compartment.

Problems solved by technology

In other words, if, although average temperature of the compartment is uniformly maintained, the temperature of the compartment varies over a large range as time passes, when the temperature of the compartment is at the lowest point, since the beverage in the supercooled state is frozen, the slush cannot be made.
However, the method of refrigerating the compartment by generating the chilled air for supercooling the beverage is not effective for the following reason.
When providing a compartment for supercooling to the conventional refrigerator, the installation of the additional evaporator for supercooling the beverage is not effective in view of structure and costs.

first embodiment

[0041] As shown in FIGS. 1 to 3, the refrigerator according to the present invention includes a main body 10 having an open front side. The main body 10 includes an outer shell 11 for forming an outer appearance and an inner shell 12 spaced apart from the outer shell 11 to form a compartment for accommodating food. Between the outer and the inner shells 11 and 12, an insulator 13 is formed to prevent chilled air from being dissipated.

[0042] The compartment 20 is divided into right and left sides by an intermediate partition 14, wherein the right side serves as a refrigerator compartment 21 for refrigerating food and the left side serves as a freezer compartment 22 for freezing food. In the rear side of the compartment 20, a chilled air generating room 15 is provided to generate chilled air to be supplied to the compartment 20. The chilled air generating room 15 includes an evaporator (not shown) for performing heat-exchange between the evaporator and ambient air to generate the chil...

second embodiment

[0055]FIG. 5 is a side sectional view illustrating a part of a refrigerator according to the present invention. Although in the embodiment of FIG. 3 the supercooling compartment 30 is disposed adjacent to the mixing room 40, in this embodiment, a supercooling compartment 60 is disposed in a mixing room 70. Hereinafter, a case of disposing the supercooling compartment 60 and the mixing room 70 in the freezer compartment 22 will be described.

[0056] As shown in FIG. 5, the refrigerator according to the second embodiment of the present invention includes the mixing room 70, disposed in the freezer compartment 22, to suction the chilled air from the freezer compartment 22 and the refrigerator compartment 21 respectively and to mix them, and the supercooling compartment 60 disposed in the mixing room 70 and separated from the mixing room 70 by a casing 61.

[0057] Like the embodiment of FIG. 3, the mixing room 70 includes a first and a second suction ports 71 and 72 communicated with the f...

third embodiment

[0065]FIG. 6 is a side sectional view illustrating a part of a refrigerator according to the present invention. The embodiment in FIG. 6 is basically similar to the embodiment in FIG. 3, but it is different from the embodiment in FIG. 3 in that the mixing room 40 is spaced apart from the supercooling compartment 30. Hereinafter, the same reference numerals are assigned to the same components and only aspects peculiar to this embodiment will be described.

[0066] As shown in FIG. 6, the mixing room 40 having the first suction port 41 and the second suction port 42 is spaced apart from the supercooling compartment 30 and is disposed in the rear side 21b of the refrigerator compartment. The mixing room 40 may be disposed higher than the supercooling compartment 30 such that the chilled air mixed in the mixing room 40 can be smoothly supplied into the supercooling compartment 30.

[0067] The mixing room 40 and the supercooling compartment 30 are connected to each other by a connector duct ...

Abstract

A refrigerator for supercooling beverage into supercooled liquid and a method of producing the supercooled liquid using the same. The refrigerator includes a mixing room provided in a main body to mix chilled air from a freezer compartment and a refrigerator compartment with each other and having a first suction port for suctioning the freezer compartment chilled air and a second suction port for suction the refrigerator compartment chilled air, and a supercooling compartment provided in the main body to be directly or indirectly refrigerated by the chilled air mixed in the mixing room. The mixing room and the supercooling compartment may be provided either in the refrigerator compartment or in the freezer compartment, or in an independent refrigerator compartment to form an independent refrigerating room separated from the freezer compartment.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of Korean Patent Application No. 2006-4207, filed on Jan. 14, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a refrigerator, and more particularly, to a refrigerator for supercooling beverage and a method of producing a supercooled liquid using the same. [0004] 2. Description of the Related Art [0005] Although a beverage is generally changed to a solid phase when its temperature is under its freezing point temperature at standard atmospheric pressure, occasionally, the beverage is not changed into the solid phase but is maintained in the supercooled state. As such, if liquid is not frozen even when it is below the freezing point and remains in the supercooled state it is in what is known in thermodynamics as a metastable state. Since the su...
