摘要： A pressure sensor in which two flat plates composed of a resilient insulating material are stuck together in parallel maintaining a predetermined gap, and provided with electrodes on the opposing surfaces of the flat plates. The load of a material to be measured is exerted on the pressure sensor by load support means, whereby the change in electrostatic capacity is detected accompanying the change in the distance between the electrodes caused by the deflection of the flat plates to detect weight. The gap of electrodes of the pressure sensor is enclosed, and apertures are formed so that the air is permitted to both enter into and come out of the gap. The surface of the pressure sensor is coated with a water-repellant material to prevent the surface from being affected by leakage current that will be caused when dust and dirt build up or when dew is formed. This makes it possible to obtain correct measurement without being affected by the temperature change or the humidity.

摘要： A roberval mechanism whose vibrational frequences varies with the weight of food being cooked is incorporated in a turntable (8). The vibration of the mechanism is magnetically transmitted to the outside of a cooking chamber, and magnetic signal is detected therefrom outside the cooking chamber. In order to reliably extract this magnetic signal, a yoke (24) is employed in the magnetic circuit. The base plate of the cooking chamber bulges so that a detection coil (10) is brought close to the roberval mechanism, thereby increasing the degree of magnetic bonding. In order to remove the noise of other electrical waves, a filter circuit (27) is provided so that a vibrational signal can be extracted accurately. In order to avoid affecting the vibrational signal of a device generating another form of magnetism, measurement is carried out only when the device is inoperative, or a magnetic shielding means is provided. In operation, the weight of food being cooked is calculated from the detected vibrational frequency, and the cooking time, the heating output, and the cooking mode are controlled according to the calculated weight. In particular, it is possible to increase convenience and realize cooking in which various cooking conditions can be finely controlled.
