DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device having a partial rapid temperature control mechanism, and more particularly, to a storage device which is selectively required when a warm article is put in a storage room. TECHNICAL FIELD The present invention relates to a home refrigerator, a commercial refrigerator, a prefabricated refrigerator, a vending machine, a commercial refrigerator, and the like, which can be rapidly cooled to a predetermined temperature by applying a small amount of cold air.

[0002]

2. Description of the Related Art Conventionally, for example, in an air-cooled refrigerator (freezer), when warm food or the like after cooking is put in a storage room,
It is not possible to selectively cool only this warm food or the like, and it is unavoidable that the temperature of the adjacent storage or atmosphere rises until the temperature in the refrigerator is balanced. That is,
A conventional refrigerator (freezer) or the like only controls the temperature of the entire interior of the refrigerator, and cannot perform partial and preferential cooling. Therefore, when a warm food or the like after cooking is added, an increase in the temperature in the refrigerator is inevitable, and it takes a certain amount of time to return to the original temperature. As a result, in some cases, there is a problem that the decay time of foods and the like is advanced.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a home refrigerator, a commercial refrigerator, a prefabricated refrigerator, a vending machine, a commercial refrigerator, and the like.
For example, even when foods are put in a warm condition from the outside, the temperature inside the refrigerator is suppressed as much as possible and the time during which the temperature is rising is shortened, so that a partial rapid rise can be prevented, such as decay. An object of the present invention is to provide a storage device with a temperature control mechanism.

[0004]

According to a first aspect of the present invention, a plurality of temperature sensors are provided in an accommodation room.
