Abstract

A refrigerator includes a main body having one or more storage spaces; one or more doors, each configured to open and close at least one of the storage space(s); one or more shelves in the storage space(s), configured to store or support food and having a plate or substantially planar form and a predetermined thickness; a cool air supply device configured to supply cool air and/or to maintain the storage space(s) at a predetermined temperature; and a multi-duct including a first cool air discharge port configured to receive the cool air from the cool air supply device, provide the cool air to the storage space(s), and/or discharge the cool air. The shelf includes a body including a flow path therein through which the cool air may flow. The body has a first side including a cool air inlet connected to the first cool air discharge port, configured to introduce the cool air into the flow path, and a second side including a third cool air discharge port configured to discharge the cool air from the flow path to the storage space(s).

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A refrigerator, comprising:
 a main body having one or more storage spaces;   one or more doors, each configured to open and close at least one of the one or more storage spaces;   one or more shelves in the one or more storage spaces and having a plate or substantially planar form and a predetermined thickness, each of the one or more shelves being configured to store or support food;   a cool air supply device configured to supply cool air and/or to maintain the one or more storage spaces at a predetermined temperature; and   a multi-duct including a first cool air discharge port, configured to receive the cool air from the cool air supply device, provide the cool air to the one or more storage spaces, and/or discharge the cool air,   wherein each of the one or more shelves includes a body comprising a flow path therein through which the cool air may flow,   the body has a first side comprising a cool air inlet connected to the first cool air discharge port configured to introduce the cool air into the flow path, and a second side comprising one or more third cool air discharge ports configured to discharge the cool air from the flow path to the one or more storage spaces.   
     
     
         2 . The refrigerator according to  claim 1 , wherein the first cool air discharge port is on a front face of the multi-duct. 
     
     
         3 . The refrigerator according to  claim 2 , wherein the first cool air discharge port extends in front of the multi-duct and is communicatively coupled to the cool air inlet. 
     
     
         4 . The refrigerator according to  claim 3 , wherein the multi-duct has a length that is oriented vertically in the one or more storage spaces. 
     
     
         5 . The refrigerator according to  claim 3 , wherein
 the plurality of first cool air discharge ports are spaced at a predetermined interval vertically along the multi-duct.   
     
     
         6 . The refrigerator according to  claim 1 , wherein the body has a side face coupled to an inner side or face of the one or more storage spaces. 
     
     
         7 . The refrigerator according to  claim 1 , wherein each of the one or more shelves comprises a plurality of the third cool air discharge ports. 
     
     
         8 . The refrigerator according to  claim 7 , wherein the plurality of the third cool air discharge ports are on a lowermost surface of each of the one or more shelves. 
     
     
         9 . A shelf for a storage space of a refrigerator and configured to be coupled to a multi-duct that is configured to receive cool air from a cool air supply device in the refrigerator, the shelf comprising:
 a cool air inlet configured to be communicatively coupled to the multi-duct; and   one or more cool air discharge ports configured to discharge the cool air from the cool air inlet, and   a flow path in the shelf, configured to discharge the cool air from the multi-duct to the storage space.   
     
     
         10 . The shelf according to  claim 9 , wherein the refrigerator includes a plurality of storage spaces. 
     
     
         11 . The shelf according to  claim 9 , wherein the cool air inlet is on a rear face of the shelf. 
     
     
         12 . The shelf according to  claim 9 , wherein the one or more cool air discharge ports are on a lower surface of the shelf. 
     
     
         13 . The shelf according to  claim 10 , wherein the one or more cool air discharge ports are configured to provide the cool air to food on another shelf below the shelf. 
     
     
         14 . The shelf according to  claim 10 , comprising a side face configured to be coupled to an inside face of the storage space. 
     
     
         15 . The shelf according to  claim 14 , wherein the cool air inlet is configured to be communicatively coupled to the multi-duct. 
     
     
         16 . The shelf according to  claim 15 , wherein the cool air inlet is configured to fit with a discharge port of the multi-duct.
