Built-in cooking appliance

Abstract

Provided is a built-in cooking appliance including: a top plate; a main body under the top plate, the main body receiving at least a heater; a fan inducing an air flow in the main body; a cabinet including a receiving portion on which the top plate is mounted; and a top frame covering an airflow opening between at least one edge of the top plate and the cabinet, wherein the main body includes at least one edge adjacent to the airflow opening and supported by the cabinet. The built-in cooking appliance can efficiently discharge warm air and prevents an inflow of external water. In addition, convenience in cleaning the built-in cooking appliance can be improved, and operation reliability of the built-in cooking appliance can also be improved by the thermally-stable state in the cooking appliance.

         9 . The built-in cooking appliance according to  claim 8 , wherein the edge of the main body adjacent to the airflow opening comprises a plate-supporting portion supporting the top plate and a cabinet-supporting portion supported by the cabinet. 
     
     
         10 . The built-in cooking appliance according to  claim 8 , wherein a plurality of plate-supporting portions and a plurality of cabinet-supporting portions are alternately disposed. 
     
     
         11 . The built-in cooking appliance according to  claim 1 , wherein the top plate comprises a top surface located at the same height as a top surface of the cabinet. 
     
     
         12 . The built-in cooking appliance according to  claim 1 , wherein the top plate comprises a bottom surface located at the same height as a top surface of the cabinet. 
     
     
         13 . The built-in cooking appliance according to  claim 1 , wherein the main body comprises at least one portion contacting a side surface of the cabinet. 
     
     
         14 . A built-in cooking appliance comprising:
 a top plate;   a main body under the top plate;   a cabinet receiving the main body, at least one portion of the main body being mounted on the cabinet;   a top frame between an edge of the top plate and the cabinet; and   an opening in the top frame, the opening being provided to discharge a fluid in the main body to an external side,   wherein the opening is located higher than a top surface of the cabinet to allow the fluid to flow out of the main body.   
     
     
         15 . The built-in cooking appliance according to  claim 14 , wherein the main body comprises an inner surface guiding the fluid in the main body into the top frame, directly. 
     
     
         16 . The built-in cooking appliance according to  claim 14 , wherein the main body comprises a side surface contacting a side surface of the cabinet.
