  • Patent number: 7759615
    Abstract: Midway along an outer circulation passage provided outside a heating chamber, a steam generating device is arranged, and, through the outer circulation passage, steam is fed to the heating chamber. A control device controls a steam generating heater arranged inside the steam generating device and a vapor heating heater provided in a space through which an air stream flowing through the outer circulation passage is returned to the heating chamber, and forms a cooking sequence by using, singly or in combination, a first heating mode that uses superheated steam obtained as a result of the steam being heated with the vapor heating heater and a second heating mode that uses hot air or radiation heat obtained by making the vapor heating heater produce heat without supply of steam.

  • Patent number: 7705274
    Abstract: A cooker has an external circulation path outside a heating chamber in which foods are to be placed. A blower sucks in gas inside the heating chamber, and forms, in the external circulation path, a gas flow that makes the sucked gas return to the heating chamber. Downstream of the blower, the external circulation path is provided with an exhaust port, in which a damper is provided. The damper closes the exhaust port during cooking, and opens the exhaust port when a door of the heating chamber is opened. After the damper is changed to a position of opening the exhaust port, the blower continues to operate until a predetermined condition is satisfied.
