  • Patent number: 11555616
    Abstract: A steam generating container A heated by a heat source includes: a water evaporation chamber into which water is supplied by a water supply device; a leading opening to lead steam from the water evaporation chamber, and ejection openings ejecting steam led through the leading opening into a heating chamber containing food. A buffer chamber connecting through the leading opening and with the ejection openings is provided between the water evaporation chamber and the heating chamber. Even when bumping water enters the buffer chamber through the leading opening, the bumping water having entered flows inside the buffer chamber. Thus, the bumping water is hardly ejected into the heating chamber through the ejection openings.

  • Patent number: 9286250
    Abstract: There is a need to cause a delay to occur less frequently than the related art during processing of an input signal in need of relatively fast processing. In a semiconductor device, a conversion portion includes first channels and second channels and A/D converts a signal input to a selected channel. A signal input to the first channel requires faster processing than a signal input to the second channel. The conversion portion receives a scan conversion instruction from a central processing unit, sequentially selects the input channels in a specified selection order, and successively performs A/D conversion. In this case, the conversion portion notifies a peripheral circuit of completion of A/D conversion after completion of A/D conversion on signals input to the first channels and before completion of A/D conversion on input signals input to all input channels.

  • Patent number: 8850968
    Abstract: A steam generation device is placed at a lower portion of a side wall of a heating chamber. A steam jet-out part is placed upper than the steam generation device of the side wall of the heating chamber with a distance from the steam generation device. Thus, even if bumping has occurred within a water storage part of the steam generation device, causing boiling water to rush out from a steam supply port into a steam supply pipe, the boiling water is prevented from intruding into a steam jet-out part.
