In addition to the above, while it has many excellent advantages, such as the fact that the temperature sensor will not burn out due to incorrect handling, it has the disadvantage that its control principle is complex and it is controlled based on the surface temperature of the food. . The various methods that have been proposed in the past are not sufficient for practical use, but the present invention makes it possible to control the temperature of the food by keeping the solid angle at which radiation is detected small and constant. Since the placement position is specified, the mechanism of the chopper chamber is simplified, and the circuit is also simplified, thereby reducing the cost. And the user can easily find the location.

All objects with a temperature higher than absolute zero emit infrared rays, and the radiant energy W per unit surface area is expressed by the following equation.

W = εσT 4 However, ε: Emissivity σ: Stelan-Boltjman's constant T: Absolute temperature The temperature of the pyroelectric detection element that receives this radiant energy changes, causing a change in surface charge, that is, this is the output becomes. This surface charge is neutralized and disappears after a certain period of time. Therefore, in order to obtain continuous output, it is necessary to provide a chopper between the pyroelectric detection element and the object to be measured to intermittent infrared rays. In this case, the amount of change in infrared rays is w = σ (ε1T1 4 −ε2T2 4 ) ε1, T1: Emissivity and absolute temperature of the food ε2, T2: Emissivity and absolute temperature of the food, and this situation is shown in Figure 1. and FIG. 1 is an infrared detector, 2 is a chipper, 3 is a food product, and 4 is a pyroelectric detection element. The total amount of infrared rays emitted from the food 3 is proportional to the surface area of the food 3, and the amount of infrared rays incident on the pyroelectric detection element 4 is inversely proportional to the square of the distance to the food 3. The amount of incident infrared rays is
In order to extract the temperature as a function of temperature, the viewing angle is always kept constant as shown in FIG. 2, and the food 3 satisfies this viewing angle, thereby making it possible to control the temperature. However, in the conventional high-frequency heating device with a radiation detector, as shown in Fig. 3, the detection range of the radiation detector 1 covers almost the entire bottom of the oven, so the area of the food 3 is smaller than the detection area. If the temperature is small, the radiation detector 1 detects the temperature of the entire detection area, so even if the food 3 with a small area reaches a high temperature, the bottom of the oven, which makes up most of the detection area, will be at a low temperature. In this case, the radiation detector 1 detected a low temperature of the food 3. This error was larger as the area of the food 3 was smaller.

Due to the above factors, food 3 was not heated properly. Therefore, as shown in FIG. 5, the detection area by the radiation detector 1 was made smaller than the area of most foods. However, if you do this, if food 3 is placed in a location other than the detection area,
The radiation detector 1 did not operate, and there was a risk of carbonization of the food 3 or an accompanying fire.

In FIG. 6, the light emitted from the lamp 11 in the chopper chamber 10 is reflected by the reflecting mirror 16, and the light from the lighting window 13 is reflected by the bottom surface of the oven 1 (in this case, the bottom surface is the food placement section). ) or the plate holder 15 (in this case, the plate holder 15 serves as the food placement part) to indicate the detection position by the radiation detector 1. Note that the radiation from the lamp 11 affects the radiation detector 1, so when the door that opens and closes the front opening of the oven is closed, the reflector 16 moves in conjunction with the door and moves from directly below the radiation detector 1 to the corner. , and the lamp 11 is turned off. Further, instead of projecting light from the daylight window 13, light can be projected from another part onto the same area as the area detected by the radiation detector 1 of the oven 9.

Since the detection position by the infrared detector is displayed with light, the food can be accurately heated within the detection range and optimal heating control of the food can be performed.
