によって行なうことができる。[Example] The present invention will be described below based on the example shown in FIGS. 1 and 2. Figure 1 is a schematic diagram showing the inside of a microwave oven, Figure 2 is a schematic diagram showing the inside of a microwave oven.
The figure is a circuit diagram showing the main parts of this embodiment. As shown in FIG. 1, the microwave oven includes a casing (1) and a turntable rotatably disposed inside the casing (1). When answering frozen food, such as frozen tuna, a special net (3) is attached to the turntable (2) and a microwave oven is used. Furthermore, a light emitting diode (4) that emits infrared light is arranged on the side wall of the housing (1).
The infrared light emitted from this is reflected by the legs of the turntable (2) as shown in the figure, and is reflected by the light emitting diode (4).
) is detected by an infrared light receiving phototransistor (5) adjacent to the infrared light receiving phototransistor (5). In other words, the light-receiving phototransistor (
5) receives the light, it is sent to the detection circuit (6) shown in Figure 2.
) detects and outputs a detection signal. Then the detection circuit (6
) receives the detection signal, and the determination circuit (7) connected to
It is determined whether the net (3) exists or not, and if it exists, it is determined that the output at the time of decompression is sufficient and is output to the control circuit (8). The control circuit (8) reduces the output of a high-frequency oscillator (not shown) of the microwave oven based on the signal from the determination circuit (7) to periodically output defrosting or the like. This periodic output can utilize the phenomenon that the legs of the turntable (2) periodically pass through the infrared light section. This output level and periodic output control can be performed by so-called microcomputer control.
以上の構成によれば、解凍用の専用キーはなくて済ませ
ることができ、パネルの簡素化をすることができ操作の
利便が図れる。According to the above configuration, a dedicated key for decompression can be omitted, the panel can be simplified, and the operation can be made more convenient.
