摘要： PROBLEM TO BE SOLVED: To obtain a rice cooker which can inhibit degrading of rice during the reservation of temperature by getting the heat reserved atmosphere deoxidized without use of a disposable deoxidizer. SOLUTION: This rice cooker 1 has a water storage tank 18 having water stored, a suction/steam conversion means which draws up water from the water storage tank 18 to be introduced into a steam chamber 21 where the water is turned to steam by heating, a steam spraying means in which a first open/ close value 24 is kept open to spray steam into a container 9 when the steam in the steam chamber 21 exceeds a fixed pressure and an air discharge means in which a second open/close valve 28 is kept open with the introduction of the steam into the container 9 to discharge the air in the container 9 outside. Thus, the air in the container 9 is replaced with the steam to produce a deoxidized atmosphere in the container 9.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating cooker performing ultrasonic vibration without using an ultrasonic vibrator, accelerating the water absorption of food inside a container, facilitating the washing of the container or the like and cooking tasty food. SOLUTION: In a cooking process in which there is sufficient water 10 in a container 3, when a high frequency current flows to an electromagnetic induction coil 5, an alternating magnetic field is generated on the basis of the direction of the current flowing to the electromagnetic induction coil 5 and the container 3 facing the electromagnetic induction coil 5 is extruded by the same frequency as the high frequency waves of the alternating magnetic field to the inner side direction of the container 3 by the high frequency waves. The high frequency waves of the alternating magnetic field are reflected by a magnetic flux modulation plate 6 and the surface of the container 3 facing the magnetic flux modulation plate 6 is extruded by the same frequency as the high frequency waves to the outer side direction of the container 3. When the frequency of the high frequency waves resonates with the intrinsic vibration frequency of the container 3, by the repetition of the extrusion of the container 3 in the inner and outer side directions, ultrasonic waves are generated in the water 10 inside the container 3.

摘要： PURPOSE:To enable the operation failure condition of a gas sensor to be detected by judging the degree of transient changes in the resistance of the gas sensor element and detecting the gas sensibility of the gas sensor element. CONSTITUTION:When a normal gas detecting condition is continued for a month, the output voltage E of an output element R is measured via an A/D converter 4 and an input circuit 5 by a command from a CPU 6 and a measured value is stored 10 as E0. Then, a switch 9 is opened via an output circuit 8 to stop the heating of the heater of a gas sensor element 1, the temperature of the heater is lowered by rendering the gas sensor element a non-electrification condition, after about 1min, the switch 9 is closed to again electrify the heater of the element 1 and the heater is again heated. After about 25sec from the start of re-electrification, the voltage E of the element R is measured again via the converter 4 and the circuit 5 and a measured value is stored 10 as Em. The voltage E0 is read from a memory 10 and a value Em/E0 is obtained. When the value Em/E0 is smaller than 1.3, an alarm 11 is operated via the circuit 8 to display or alarm an abnormality, urging inspection and the replacement of the element 1.

摘要： PROBLEM TO BE SOLVED: To eliminate the possibility of fungus contamination, prevent the rice from being swollen by the difference in the temperature distribution and suppress the deterioration of rice due to heat preservation.
SOLUTION: In a sucking process, an opening/closing valve A31 is closed, an opening/closing valve B32 is opened, an opening/closing valve C37 is opened, an opening/closing valve D38 is closed, a suction device 34 is actuated to suck the air in a space surrounded with an inner pot 23 and an inner lid 28 and make the pressure inside the rice cooker smaller than the atmospheric pressure. Therefore, an excessive moisture which is not absorbed in the rice in the rice cooker is evaporated to lower the temperature to that equivalent to the vaporization latent heat of water, and the output of a pressure sensor 40 is set to a steam pressure of 31 kPa (234 mmHg) which is equivalent to 70 °C suitable for the heat preservation temperature of the rice.
