Cooking appliance

A cooking appliance, comprising:

• a main body having a cooking chamber formed therein and including a rear surface configured to define a rear boundary of the cooking chamber, a lower surface configured to define a lower boundary of the cooking chamber, and at least one side surface configured to define a side boundary of the cooking chamber;
• a lower case provided below the lower surface and having an accommodation space formed therein;
• first and second heaters, the second heater being installed in the accommodation space and configured to generate heat;
• a first discharge port configured to allow an inside of the lower case having the accommodating space formed therein to communicate with an outside of the main body;
• a second discharge port configured to allow an inside of the cooking chamber to communicate with the outside of the main body;
• and
• a flow path connection member configured to form a flow path guide to guide heat discharged through the first discharge port toward the second discharge port, wherein the flow path connection member includes:
• duct sections provided outside the cooking chamber and configured to form an outer wall surrounding the flow path guide from the outside of the main body;
• and
• at least one coupling flange configured to couple the duct sections to at least one of the lower case or the at least one side surface, wherein the flow path guide forms a path that connects the first discharge port and the second discharge port in a space surrounded by the duct sections, and wherein the at least one coupling flange protrudes from an edge of each of the duct sections abutting the at least one side surface of the main body or a side wall of the lower case and is parallel to the at least one side surface of the main body or the side wall of the lower case to be in surface contact with the at least one side surface of the main body or the side wall of the lower case.

• at least one coupling flange configured to couple the duct sections to at least one of the lower case or the at least one side surface, wherein the flow path guide forms a path that connects the first discharge port and the second discharge port in a space surrounded by the duct sections, wherein the duct sections include:
• a first duct section configured to form an outer wall surrounding a peripheral portion of the first discharge port;
• and
• a second duct section configured to form an outer wall surrounding a peripheral portion of the second discharge port, and wherein the first duct section is pressed against the lower case, and the second duct section is pressed against the at least one side surface inside at least one side space of the main body.
