Claim:
1. An oven comprising: a casing having at least one inhalation hole through which air outside is introduced to and an ejection hole through which air inside of the oven is discharged to outside; a cooking chamber placed inside the casing and having an opening; a door that is installed to open/close the opening and forms a flow path of air inside the door using a plurality of sheets of glass including inner glass to seal the cooking chamber; a cooling fan that is installed at an outer portion of the cooking chamber so as to cool the door by inhaling external air through the inhalation hole; a cooling flow path that is installed so that air inhaled by the cooling fan is capable of flowing toward the door in a first direction, so as to generate a flow of air inside the door; door flow paths that are installed so that air inhaled at an end portion of the door is capable of passing through the door and flowing toward the other end portion adjacent to the cooling flow path; and a cooling guide that is installed at the cooling flow path adjacent to the door flow paths and comprises a first end portion that extends in the first direction so as to narrow a width of the cooling flow path; an air guide that is installed adjacent to the ejection hole so as to change a direction of air driven by the cooling fan so that high-temperature vapor from the cooking chamber is capable of being diffused downwards; and a movement unit that contacts the air guide and moves upwards and downwards based on the received signal and adjust the air guide, wherein the first end portion is disposed posterior to an inner side surface that forms the door flow paths of the inner glass in the first direction so as to prevent a flow of air that passes through the door flow paths and is directed toward the outside from being disturbed.
