Cooking apparatus

A cooking apparatus comprising:

• a main body that includes a cooking room in which an opening is formed at a front side of the cooking room, the opening configured to be capable of allowing food to be put in and taken out of the cooking room through the opening, and to contain heat for cooking the food;
• and
• a door rotatably coupled to the main body at a front side of the opening and configured to open or close the opening, the door including:
• an outer glass that forms a front side of the door,
• an inner glass positioned behind the outer glass to face the cooking room,
• a door duct positioned between the outer glass and the inner glass such that the door duct forms an accommodating space below the door duct and above the inner glass, and configured to guide air flowing between the outer glass and the inner glass to outside of the door,
• an insulation member positioned between the door duct and the outer glass, and
• a blocking member positioned in the accommodating space formed between the door duct and the inner glass and configured to prevent heat contained in the cooking room from leaking out from between the inner glass and the door duct.
