Benefits of technology

The present patent aims to provide a refrigerator with a new type of refrigerating-compartment grill assembly that can improve refrigerating efficiency by allowing cool air to flow through the refrigerating compartment and then discharge it. The refrigerator also includes a refrigerating-compartment retrieval flow path that prevents insulation loss and a second transfer flow path that reduces insulation loss. Overall, this refrigerator design simplifies the overall structure without the need for a separate duct for retrieving cool air and improves the efficiency of refrigerating.

Problems solved by technology

Particularly, the above-described retrieval flow path makes it very difficult to form another flow path in the partition wall.
That is, selection of the retrieval flow path is limited when forming a new flow path in the partition wall.
However, the insulation performance of the partition is decreased due to the above-described retrieval flow path.

Abstract

Proposed is a refrigerator including a cabinet having a freezing compartment above a partition wall and a refrigerating compartment therebelow, an evaporator positioned behind the freezing compartment and generating cool air, a freezing-compartment grill assembly positioned in front of the evaporator inside the freezing compartment, a blowing fan for blowing the cool air being mounted in the freezing-compartment grill assembly, and a refrigerating-compartment grill assembly positioned behind the refrigerating compartment, wherein a refrigerating-compartment discharge flow path guiding discharging of the cool air supplied from the freezing-compartment grill assembly into the refrigerating compartment, and a refrigerating-compartment retrieval flow path guiding flowing of the cool air retrieved from the refrigerating compartment into the freezing compartment are formed together in the refrigerating-compartment grill assembly.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to Korean Patent Application No. 10-2021-0002287, filed on Jan. 8, 2021, the entire contents of which is incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present disclosure relates to a refrigerator including a grill assembly in which a discharge flow path and an absorption flow path for supplying and retrieving cool air into a storage compartment are provided together.Description of the Related Art[0003]Usually, refrigerators are a household appliance that is configured to store various foodstuffs and drinks for a long period of time using cool air that is generated by circulating refrigerant with a freezing cycle.[0004]Refrigerators are categorized into top freezer type refrigerators in which a freezing compartment is arranged over a refrigerating compartment, bottom freezer type refrigerators in which the freezing compartment is arra...
