Steam generator and heating cooker including steam generator
View Patent ↗A steam generator includes a water storage chamber that stores water and at least one heating portion that heats the water in the water storage chamber to generate steam. A water supply device supplies water into the water storage chamber. A plurality of fins are provided in the water storage chamber. The water storage chamber has a steam spout port from which the steam generated by the heating portion spouts. The plurality of fins extend along a steam-generating direction under the steam spout port, and are separated from each other and cross the heating portion. The heating portion may be above and below a water surface that emerges in the water storage chamber during heating.
1. A steam generator comprising:
a water storage chamber which stores water;
at least one heating portion that heats water in the water storage chamber and is configured to generate steam;
a water supply device that supplies water into the water storage chamber; and
a plurality of fins in the water storage chamber,
wherein the water storage chamber comprises an aluminum die cast body portion that has an opening, and a water storage chamber cover opposite to the opening,
wherein the water storage chamber has a steam spout port from which the steam generated by the heating portion spouts,
wherein the plurality of fins extend from a first surface as a part of the body portion of the water storage chamber along a steam-generating direction under the steam spout port, the plurality of fins separated from each other and crossing the heating portion,
wherein distal ends of the fins are spaced from a second side surface as a part of the water storage chamber cover opposite to the first side surface of the water storage chamber, and
wherein the heating portion is cast in the body portion of the water storage chamber.
2. The steam generator according to claim 1 , wherein a cross-sectional area defined by the water storage chamber and the fins in a plane perpendicular to the steam-generating direction is equal to or larger than a cross-sectional area of the steam spout port.
3. The steam generator according to claim 1 , wherein the at least one heating portion is provided each of above and below a water surface that emerges in the water storage chamber during heating.
4. A heating cooker including the steam generator according to claim 1 .
