Abstract

PURPOSE:To perform opening and closing of an infrared ray guide opening at a low cost without generating impact noise by a method wherein the rotation position of a rotary body is detected, and a chopper means is driven following release of the infrared ray guide opening by means of the rotary body. CONSTITUTION:An infrared ray guide opening 4 formed in an upper wall surface 5 of a heating chamber 1 and guiding infrared rays from a food 2 to the outside of the heating chamber 1 is provided. When it is not necessary that a food temperature is detected, the infrared ray guide opening 4 is closed by means of an AC motor-driven rotary body mounted in addition to a chopper means 7. The chopper means 7 is driven following release of the infrared ray guide opening 4. Namely, opening and closing of the opening 4 is effected by means of a rotary disc 13 driven with the aid of an AC geared motor 16. This constitution prevents the generation of impact noise like that generated during drive by means of a solenoid, and eliminates a DC source circuit used when drive by a solenoid is effected.

(b) Conventional Japanese Patent Publication No. 56-42808 discloses that infrared rays from food are led out from an infrared ray extraction opening U provided on the wall of the heating chamber, and then interrupted by a chopper means driven by a motor. W4l, which detects food temperature with an infrared detection means and controls the heating by knowing the temperature of the food based on the temperature signal output by the infrared detection means! i device is disclosed. Furthermore, in such a cooker, a solenoid-driven shutter is provided separately, so that there is no need to know the temperature of the food, and the infrared radiation emitting opening is closed by the shutter at 1 o'clock. This prevents water vapor, oil droplets, etc. generated from the food from passing through the openings to the outside of the heating chamber and contaminating the infrared detecting means, etc. as much as possible. Alternatively, as a means for suppressing such contamination, it is also possible to use the chopper means and stop the chopper means at a position where the infrared light emitting opening is closed when there is no need to know the food/temperature. However, when the opening is opened and closed by a solenoid-driven shutter as in the former case, a loud impact sound that is harsh on the ears is generated when the shutter is driven. In addition, the solenoid is generally driven with DC current since AC driving causes whirring, but in this case, a DC t source circuit is required, resulting in high cost. Furthermore, when continuously opening or closing the aperture with the shutter, the solenoid must be continuously driven, which consumes power! ? The quantity is large. Furthermore, the power consumption means is driven even when there is no need to know the temperature of the food, and power consumption increases in this respect as well.

On the other hand, in the case of the latter, in which the opening is opened and closed by three chipper means, the chipper means usually performs infrared intermittent intermittent infrared rays at several Hz to several tens of Hz, and the rotation speed is relatively far. Therefore, it is difficult to instantly and reliably stop the senfu tsupa means at the opening/closing position when the opening is closed.

There is no need for a DC power supply circuit that is used when performing this process, and the cost does not increase. Furthermore, once the opening 4 is opened or closed,
Thereafter, the opening or closing of the opening 4 is maintained without applying AC power to the motor 16, and power consumption does not increase.

Furthermore, the electromagnet 11 of the chopper means 7 is driven to intermittent infrared rays only when the chopper drive enable signal is generated based on the opening of the aperture 4, which undesirably increases the power consumption associated with intermittent infrared rays. Not at all. Furthermore, the opening and closing of the opening 4 is performed by a rotating circle [13], and the chopper means 7 that cuts off infrared rays is not used. There is no need to stop the chipper means 7 to close the opening 4, and the closing of the opening 4 can be stopped instantaneously and reliably.
