Patent attributes
A steam generator includes: a water storage chamber which stores water therein, a first heating portion which heats water stored in the water storage chamber to generate steam, a water supply device which supplies the water storage chamber with water, a controller, a steam spout port which ejects steam generated in the water storage chamber therethrough, and a temperature detector which detects a temperature in the water storage chamber, wherein a water level in the water storage chamber is calculated depending on the temperature detected by the temperature detector, and wherein at the time of steam generation, the controller is configured to perform a water supply control of the water supply device based on the calculated water level such that a water volume from the first heating portion to a water surface is smaller than a water volume from the first heating portion to the bottom surface of the water storage chamber.
