Rapid cryocooler utilizing spray holes to cool a beverage

摘要

A refrigerator is disclosed. The refrigerator includes a refrigerator body having a storage chamber defined therein, a refrigeration cycle device for cooling the storage chamber, a chilling case for receiving a beverage container such that the chilling case surrounds the beverage container in a contact manner, and a rapid cooling device, having a case receiving part for receiving the chilling case, for cooling a coolant using the refrigeration cycle device and spraying the cooled coolant to an outside of the chilling case in a vicinity of the chilling case. A beverage is cooled in a state in which the beverage container is not in direct contact with the coolant, whereby the coolant is not present at the outside of the beverage container, and therefore, the beverage container is kept sanitary.

主权项

1. A refrigerator, comprising:
a refrigerator body having a storage chamber defined therein; a refrigeration cycle device to cool the storage chamber; a chilling case to receive a beverage container such that the chilling case surrounds the beverage container in a contact manner; and a rapid cooling device, having a case receiving portion that receives the chilling case, to cool a coolant using the refrigeration cycle device and spray the cooled coolant onto an outer circumferential surface of the chilling case, wherein the rapid cooling device comprises a rapid cooling body, in which the case receiving portion is defined, having a plurality of spray holes to spray the coolant onto the outer circumferential surface of the chilling case, and wherein the rapid cooling body comprises:
an inner cylindrical body, in which the case receiving portion is defined and through which the plurality of spray holes is formed to spray the coolant onto the outer circumferential surface of the chilling case; andan outer cylindrical body that surrounds the inner cylindrical body to define an internal channel to allow a coolant to pass between the inner cylindrical body and the outer cylindrical body.
