refrigerator

Abstract

The invention provides a refrigerator which improves property of energy saving and property of food preservation by supplying cool air into a freezing chamber while limiting operation of independent cooling of a refrigerating chamber. The refrigerator has a plurality of storage rooms (3, 4), and a first blower (14) and a second blower (13) supplying cool air to the plurality of storage rooms. The refrigerator is provided with an air channel (4f) of the first blower (14) and an air channel (3f) of the second blower (13), wherein the air channel (4f) and the air channel (3f) are partially adjacent and partially separated by an edge part (L). An air capacity control part (37) which connects the air channels (3f, 4f) is arranged at the edge part (L) where a discharge side of the first blower (14) provided with the air channel (4f) of the first blower (14) and a discharge side of the second blower (13) provided with the air channel (3f) of the first blower (13).

Description

technical field [0001] The invention relates to a refrigerator. Background technique [0002] A refrigerator is known that includes a plurality of storage rooms in different temperature zones, and that cool air generated by heat exchange with a single cooler is blown by a plurality of air supply units corresponding to the plurality of storage rooms. [0003] In the refrigerator described in Patent Document 1, a refrigerating room fan and a freezing room fan are provided, the temperature of the storage room is detected by temperature sensors provided in the refrigerating room and the freezing room, and the rotational speeds of the refrigerating room fan and the freezing room fan are controlled in conjunction with the temperature sensors. , to adjust the air volume delivered to the refrigerator and freezer to achieve the set temperature of the storage room. [0004] In the refrigerator described in Patent Document 2, a damper is provided in the middle of the air passage of th...

AI Technical Summary

Problems solved by technology

[0016] However, there is no description about the independent cooling operation of the refrigerator compartment for improving energy saving, and there is no description about the flow of cold air in the refrigerator compartment and the freezer compartment when the refrigerator compartment individual cooling operation is performed.

[0017] As mentioned above, in Patent Document 1 and Patent Document 2, although a refrigerator is provided with a refrigerator fan for cooling the refrigerator compartment and a freezer fan for cooling the freezer compartment, there is no improvement in improving the performance of the refrigeration unit by implementing a separate cooling operation for the refrigerator compartment. Mention of energy-saving operation

In addition, there is no description about the rapid cooling operation of the refrigerator compartment that rapidly cools the refrigerator compartment in a short time using the same cold air cycle as that of the refrigerator compartment individual cooling operation.
