  • Publication number: 20210204371
    Abstract: A heating cooking apparatus includes a heating chamber, a main body outer case, a fan, a first duct member, and an air sending unit The fan is disposed in a first space. The first space is formed between an outer surface of the heating chamber and an inner surface of the main body outer case. The first duct member is attached to the outer surface of the heating chamber. The first duct member separates a blown air flow into a first air flow and a second air flow. The first air flow flows inside the first duct member. The second air flow flows outside the first duct member. The air sending unit includes an air sending chamber and a heater. The heater is located in the air sending chamber. The air sending chamber is disposed at a position where the air sending chamber is exposed to the first air flow and is not exposed to the second air flow.

  • Patent number: 10710834
    Abstract: A folding apparatus includes a folding device to fold a sheet bundle, an additional folding device, a conveyer, and control circuitry. The additional folding device includes a pressure roller disposed downstream from the folding device in a sheet conveyance direction and configured to press the sheet bundle after the folding device folds the sheet bundle and a sheet support member disposed opposite the pressure roller via the sheet bundle. The conveyer conveys the sheet bundle to a position at which the additional folding device presses the sheet bundle and hold the sheet bundle at the position. The control circuitry causes the additional folding device to perform additional folding processing on a first position of the sheet bundle, the conveyer to move the sheet bundle to a second position different from the first position, and the additional folding device to perform the additional folding processing at the second position again.
