センサの検知感度が悪い。(b) Conventional technology For example, an electronic device in which a humidity sensor for detecting the physical state of the heating chamber, that is, humidity, is installed in the exhaust duct communicating with the heating chamber, and a wind-powered rotary stirrer for stirring the microwaves is placed inside the heating chamber. In the microwave oven, when air is supplied into the heating chamber, the stirrer is rotated and the atmosphere inside the heating chamber is exhausted to the exhaust duct. The atmosphere discharged into such a discharge duct contains water vapor generated from the food during heating. When the atmosphere is discharged to the exhaust duct in this manner, the humidity sensor is exposed to the atmosphere and detects the humidity in the heating chamber. Heating is controlled based on this detected humidity. However, in such a case, although it is sufficient for the rotation of the stirrer to be performed by the large amount of air supplied into the heating chamber, the large amount of air supplied into the heating chamber is sufficient to rotate the stirrer.・\
The amount of atmosphere emitted is large, and therefore the proportion of the amount of water vapor generated from food contained in this atmosphere is relatively large.
Sensor detection sensitivity is poor.

えなくなる。On the other hand, as disclosed in Utility Model Application No. 62-119431, if the heating chamber is divided into a food placement section and a star placement section and the air supplied into the heating chamber is divided into these placement sections, the food placement section The amount of air supplied to the food storage area decreases, thereby reducing the amount of atmosphere discharged from the food placement section, and the ratio of the amount of water vapor to the amount of atmosphere increases, thus improving the detection sensitivity of the humidity sensor. . However, in this case, the amount of air supplied to the Stark placement portion similarly decreases, making it impossible to rotate the Stark sufficiently.

A magnetron (4) is arranged at the upper part of the heating chamber (2) and stirs the microwaves, and (5) is made of a material that passes microwaves. 2) a partition plate that divides the interior into a food placement area (6) and a stark placement area (7);
(8) is a propeller fan as a wind supply means. Regarding the wind generated by the propeller fan, the following parallel flows occur. That is, a part of it is supplied to the food placement section (6) through the duct (9), and an atmosphere containing water vapor generated from the food during heating is discharged from the food placement section (6) accordingly. be done. Another part of the air is supplied to the Stark arrangement part (7) through the duct (10) on the side after cooling the magnetron (3), and after rotating the Stark (4), the Stark arrangement part (7 ) is discharged from. Furthermore, the remaining air is used to cool the high voltage transformer (11) that provides high pressure to the magnetron (3), and then to the exterior bottom plate (
1a) is directly discharged to the outside. <12) is an exhaust duct that communicates with the food placement section (6) and through which the atmosphere discharged from the food placement section (6) flows; (13>) is exposed to the atmosphere flowing through the exhaust duct and is connected to the food placement section ( 6) It is a humidity sensor that detects the humidity inside the room.

向上したものとなっている。At this time, not all of the air supplied to the heating chamber (2) is supplied to the food placement section (6), but the air is supplied separately from the food placement section (7). Therefore, since the amount of air supplied to the food placement section (6) is small, the amount of atmosphere discharged from the food placement section (6) is also small, and therefore the ratio of the amount of water vapor generated from the food to the amount of atmosphere is relatively low. This greatly improves the detection sensitivity of the humidity sensor (13).

サ(13)の検知精度の低下は生じない。Further, the temperature of the air after cooling the magnetron (3) has increased, and the heated air is supplied to the food placement section (6), thereby causing the heated atmosphere to flow into the exhaust duct ( 1
2) and the humidity sensor (13) is exposed to this elevated temperature atmosphere, the detection accuracy of the humidity sensor (13) decreases.However, the heated air after cooling the magnetron (3) is exposed to the food. It is not supplied to the arrangement section (6) but is supplied only to the stirrer arrangement section (7), so that the detection accuracy of the humidity sensor (13) as described above does not deteriorate.

れる。Thus, the exhaust duct 1-(12) is connected to the food placement section (
The atmosphere exhausted from 6) is transferred to the left rear intake hole (14) (
14)... is configured to lead to the stirrer arrangement section (7). As a result, the amount of air supplied to the stirrer placement section (7) via the duct (10) is not all of the amount of air supplied to the heating chamber (2), but is similarly small; Furthermore, the exhaust duct (12
) is also supplied with atmosphere from the food placement section (6), so that sufficient rotation of the stirrer 4) is achieved.

その後下降し外装底板(1a)から外部へ排出される。Regarding the exhaust from the stirrer arrangement part 7), the wind supplied through the duct (10) is mainly exhausted from the exhaust holes (15) (15) on the left front part.
Thereafter, it descends and is discharged to the outside through the exterior bottom plate (1a).

と食品配置部(6)からの雰囲気とは充分に混合する。Figures 5 to 8 show microwave ovens according to other embodiments of the present invention, and only the differences from the previous embodiments will be explained. The atmosphere is introduced to the stirrer arrangement section (7) through the intake holes (18) (18) on the upper left side. Furthermore, the exhaust from the stirrer arrangement part (7) is carried out through the rear exhaust hole (16)<16)... and the duct (17).
). In this case, there is only one exhaust route from the stirrer arrangement section (7), so that by the time the exhaust is exhausted from this exhaust route, the magnetron supplied to the stirrer arrangement section (7) is The heated air and the atmosphere from the food placement section (6) are sufficiently mixed.

とができる。Here, in the stirrer arrangement section (7), the water vapor contained in the atmosphere from the food arrangement section (6) condenses due to the action of the heated air, and therefore water droplets accumulate in the stirrer arrangement section (7). It can be used in situations where rust may occur.

The connection part (20) with the exhaust duct (12) is arranged so as not to face the exhaust duct (12). That is, the connecting portion (20) is a seat press portion (21) formed on the side wall of the heating chamber (2).
and a plate (22) that covers the seat pusher. As a result, the above connection part (20)
The shield against water vapor is lost. Furthermore, the protruding portion of the sensor (13) into the exhaust duct (12) is small, so that the flow of atmosphere within the exhaust duct (12) is not unnecessarily disturbed, and the detection sensitivity of the sensor (13) is reduced. is stable, and the exhaust duct (12) can be made smaller due to the reduced number of protruding parts.
