Patent ID: 7341055

Claim:
An overheated steam oven, comprising: a cabinet to define a cooking cavity therein; an overheated steam generator to supply overheated steam into the cooking cavity; an overheated steam discharger, including a steam discharging path, and a cooling water path, which is provided on the steam discharging path, to exchange heat with the overheated steam discharged from the cooking cavity to the outside, and to discharge the overheated steam from the cooking cavity to an outside after condensing the overheated steam, wherein the overheated steam discharger comprises: first and second steam discharging pipes extending from the cooking cavity to the outside of the cooking cavity to define the steam discharging path, and a steam condensing vessel between the first and second steam discharging pipes, to define the cooling water path therein, the steam condensing vessel comprising: a steam condensing chamber in the steam condensing vessel, to pass the overheated steam discharged from the cooking cavity, a steam inlet and a steam outlet on opposite sidewalls of the steam condensing vessel, to be coupled to the first and second steam discharging pipes, respectively, a cooling water inlet chamber in the steam condensing vessel and partitioned from the steam condensing chamber, with a cooling water inlet provided on a predetermined portion of the cooling water inlet chamber, a cooling water outlet chamber in the condensing vessel and partitioned from both the steam condensing chamber and the cooling water inlet chamber, with a cooling water outlet provided on a predetermined portion of the cooling water outlet chamber, and a cooling water pipe in the steam condensing chamber to define the cooling water path along which cool water flows from the cooling water inlet chamber to the cooling water outlet chamber via the steam condensing chamber; and a partition provided in the steam condensing chamber to partition a space defined in the steam condensing chamber, to increase a length of the steam discharging path in the steam condensing chamber.
