An inlet and an outlet are formed at the air layer, and a blowing fan is mounted at the inlet. Bent guide members are disposed in the air layer to guide air such that the air uniformly flows throughout the air layer.

Abstract: An oven capable of preventing heat transfer from one cooking space having relatively high temperature to another cooking space having relatively low temperature along each side plate of a cooking chamber having a plurality of partitioned cooking spaces. The oven includes an insulating unit and a cooling unit mounted at each side plate to prevent heat transfer between first and second cooking spaces along each side plate. The insulating unit includes a slit formed right under the partition, an insulating member fitted in the slit, and a supporting member attached to the inside of each side plate. The cooling unit includes an air guide member attached to the outside of each side plate to cover the insulating member, and a blowing fan connected to the air guide member to forcibly blow outside air to the air guide member.
