Integrated cooling device and refrigerator having same

Abstract

In a concentrated cooling apparatus and a refrigerator having the same capable of performing cooling operation instantly by discharging intensively cold air to a high-temperature load occurred region inside a chilling chamber, a concentrated cooling apparatus of a refrigerator includes housings respectively installed to at least one cold air guide path formed at the side wall of a chilling chamber in order to guide cold air to the side wall of the chilling chamber; a nozzle rotatively supported by the housings and jetting cold air intensively to a high-temperature load occurred region inside the chilling chamber when the high temperature load occurs at the certain region; a temperature sensor installed on the front of the nozzle, rotating with the nozzle and sensing the high-temperature load occurred region; and a nozzle driving unit installed at a certain side of the housings to rotate the nozzle.

Description

technical field [0001] The present invention relates to a refrigerator, in particular to a centralized cooling device, and a refrigerator with such a device, which can complete the rapid cooling process by violently spraying cold air to the area where the high temperature load occurs inside the refrigerator compartment , to keep the temperature inside the refrigerator even. Background technique [0002] Generally, refrigerators are divided into a freezer compartment for storing frozen food and a refrigerator compartment for storing cooled food, and have a cooling circulation device for supplying cold air into the freezer compartment and the freezer compartment. [0003] figure 1 is a cutaway perspective view of an existing refrigerator, and figure 2 It is a sectional view explaining the refrigerating chamber of the above-mentioned conventional refrigerator. [0004] Existing refrigerator is made up of following various components: a main body 104 with a pair of doors 102...

Problems solved by technology

[0011] But, in this existing refrigerator, the cold air exhaust duct is installed on the top of the refrigerator compartment, and the cold air flows into the lower part from the upper part of the refrigerator compartment through the cold air exhaust holes formed on the cold air exhaust duct. , therefore, the temperature of each part of the refrigerating room varies greatly according to the distance from the cold air exhaust hole.

Moreover, since the cold air is exhausted only from the cold air exhaust duct, when a large high temperature load occurs due to food stored in the refrigerator, etc., it takes a long time to make the temperature inside the refrigerator uniform, As a result, the freshness of the food stored in the refrigerator will decrease due to the prolonged cooling time.

[0012] In addition, since the temperature sensor and the cold air exhaust hole are fixed at a certain position, it is dif...
