摘要： PROBLEM TO BE SOLVED: To keep the temperature of boiled rice in a pan in a heat retaining period, and prevent the drying of the boiled rice by forming a steam cylinder on the upper part of an exhaust port provided on a radiating plate, and covering the upper surface of the steam cylinder with a box-like moisture retaining cap. SOLUTION: The steam generated from a pan in rice cooking is raised from an exhaust port 4 to a steam cylinder 5 to push up a circulating valve 11 and block a circulating hole 10, penetrated into a moisture retaining cap 7 through an air port 9, and released to the outside through a steam port 8. A glutinous liquid is also penetrated into the moisture retaining cap 7, but it is liquefied from bubbled state since the inner part has a low temperature, and stored in the bottom part. On the other hand, since the circulating valve 10 of the moisture retaining cap 7 covers the exhaust port 4 of a radiating plate 3 in heat retaining, the temperature of boiled rice in the pan is hardly influenced by the outside air, and a high heat insulating effect can be provided. Further, the moisture in the pan is also hardly released to the outside by throttling the exhaust port 4, the steam port 8, the air port 9 and a passage, and the boiled rice is prevented from being dried.

摘要： PROBLEM TO BE SOLVED: To control the humidity in a main body by driving a steam port opening/closing device during the heat retaining process with a control means, and opening or closing a steam port at the proper timing. SOLUTION: When a motor is rotated, a magnet 5a is circularly moved, and a magnet 5b arranged at the upper section is attracted or repulsed. When the whole unit constituting a steam port 5 is displaced upward, a spherical steam presser 5c pressing the upper section of the steam discharge port 5d of the steam port 5 is moved upward. A control means 9 controls a steam port opening/closing device 6 to open the steam port 5 when the rice cooking process is finished. The temperature of cooked rice is naturally cooled by heat radiation, and the prescribed temperature is detected by a pot temperature detecting means 7 or a cover temperature detecting means 8. The steam port opening/closing device 6 is controlled to close the steam port 5. The steam port 5 can be opened or closed at the optional timing, the steam emitted from the cooked rice is discharged to the outside, the swelling-up of the cooked rice due to dew condensation can be prevented, and the steam quantity in a main body 1 is invariably controlled to the proper quantity.

摘要： PROBLEM TO BE SOLVED: To report it to a user that the ratio of water is too high in a cooked object by operating a reporting device to stop heating when rice cooking is not finished at the prescribed time after boiling is detected. SOLUTION: When a heater 11a is excited, a cooked object 17 is heated via a pot 12 to start the rice cooking process. When the temperature of the cooked object 17 approaches the boiling point, the temperature of a boiling detecting device 16 rises, and boiling is judged at the prescribed temperature. When a user sets the ratio of the water 17b in the cooked object 17 too high by mistake, the period until the water 17b is absorbed by rice 17a becomes long. If the rice cooking process is not finished when the prescribed period of about 20min elapses after the boiling detecting device 16 detects boiling, a water quantity abnormality can be judged. A reporting device 14 is operated, and this effect is displayed on a liquid crystal. The heating by a heating device 11 is stopped to report the cause to the user, and the reduction of the product life and boiling-over can be decreased.

摘要： PROBLEM TO BE SOLVED: To increase the work efficiency and reduce the cost by directly winding a cover induction heating coil on an integrally molded induction heating coil support. SOLUTION: A cover induction heating coil wire 21 is directly wound on a cover induction heating coil support 24, and the work efficiency can be increased. The cover induction heating coil wire 21 is made of a lead wire with an insulating cover. The cover induction heating coil wire 21 enters between the coil pressing projections 24a, 24d of the cover induction heating coil support 24, and is wound on the cover induction heating coil support 24. The cover induction heating coil wire 21 is brought into contact with the coil pressing projections 24a, 24d when it is wound. Coil pressing recesses 24b, 24c are arranged on the opposite side, the cover induction heating coil wire 21 is not directly pressed when it is wound, and the insulating cover of the cover induction heating coil wire 21 is not damaged.
