An oven comprising a heat cleaning mode in which inner walls of a cooking chamber and an inner side of a door assembly facing the cooking chamber are cleaned using a high temperature inside the cooking chamber, the oven comprising:

• a casing:
• the cooking chamber located inside the casing and having a shape with an open front;
• and
• the door assembly, comprising at least one flow path in an inner space, and configured to open and close the open front of the cooking chamber,
• wherein the door assembly comprises:
• a handle member having a groove concaved inward on a top of the door assembly,
• an inlet formed in a bottom of the door assembly and configured to allow an air inflow into the inner space,
• an outlet located on a top of the door assembly at a rear of the handle member and configured to provide a space to allow air to move outside the door assembly,
• a first flow path formed in a position facing a rear side of the door assembly and configured to provide a space to allow air to move from a bottom of the door assembly to a top of the door assembly,
• a second flow path formed in front of the first flow path while being separate from the first flow path and configured to provide a space to allow air to move from the bottom of the door assembly to a top of the door assembly,
• a third flow path formed between the rear side of the handle member and the rear side of the door assembly and connected to the outlet, and
• a shielding member installed inside the first flow path and shielding an air inflow inside the first flow path.

An oven comprising:

• a casing;
• a heating chamber located inside the casing;
• and
• a wall assembly having an inner space, the wall assembly comprising:
• a plate installed inside the inner space to divide the inner space,
• a shielding member located between the plate and a side of the wall assembly and configured to shield an air flow,
• an inlet formed in the wall assembly and configured to allow an inflow of air from outside of the wall assembly into the inner space, and
• an outlet located in the wall assembly and configured to provide a space to allow air to move outside the wall assembly.

A wall assembly of an oven, the wall assembly comprising:

• a plate installed in an inner space of the wall assembly and configured to divide the inner space;
• a shielding member located between the inner plate and a side of the wall assembly and configured to shield an air inflow;
• an inlet formed in the wall assembly and configured to allow an inflow of air from outside of the wall into the inner space;
• and
• an outlet located in the wall assembly to provide a space to allow air to move outside the wall assembly.
