摘要： PURPOSE:To improve efficiency and to improve the finishing of a steam pressed material by controlling the driving frequency of a pump according to the temperature of an iron base and making steam generation quantity into appropriate one. CONSTITUTION:When the generation of steam is instructed by operating a steam generation command part, a microcomputer 19 first confirms that a steam flag is under an OFF state, displays the OFF state on a display part 5, and turns the steam flag on. Further, the microcomputer 19 controls the temperature of an iron base 4, controls the driving of a pump 7 with the required driving frequency according to on/off control for a transistor, and generates the required quantity of steam. Thus, since the driving frequency of the pump is adjusted according to the temperature of the iron base, the steam quantity can be controlled in detail as compared to a conventional iron in which the driving frequency is constant for each temperature zone regardless of the temperature of the iron base.

摘要： PURPOSE:To allow baking of a good-quality bread by controlling a fermentation process based on the ratio of resistance change on the basis of the resistance value at the time when a given setup time in the beginning of kneading where a trace quantity of gas exists has passed. CONSTITUTION:When given materials of bread are put into a container 1 and a start switch of operation part is on, a control 25 drives a motor 11 and turns a blade 13 to begin a kneading process of bread materials. When a time T has passed after the kneading begins, the output V0' of a gas sensor 23 is detected, and the resistance value R0' that is a reference value is calculated based on it. When the kneading process is completed and rotation of the motor 11 is stopped, and a fermentation process is begun, the control 25 keeps the temperature in the container 1 at a given temperature to fermentate for a given time by energization control to a heater 3, then drives the motor 11 to degass twice for a given time, and the first fermentation and the second one are performed. Next, in molding fermentation, the control 25 detects the resistance value RH of a gas sensor calculated based on the output VH of a fermentation sensor at all time, and when the ratio RH/R0' to the reference value reaches to the set value, mold fermentation is completed and the last baking process is begun.
