受け皿１０とを備えている。The high-frequency heating device 4 includes a heating chamber 5 for containing an object to be heated, a heating means 6 provided on the top of the heating chamber for heating a heater, and a high-frequency heating device provided on the bottom of the heating chamber for high-frequency heating. It is provided with a high frequency generating means 7, a high frequency heating element 9 having a high frequency heating film 8 on the back surface, and a tray 10 on which an object to be heated is placed.

たレール１２に載せて使用する。The high frequency transmitted from the high frequency generating means 7 is
The high-frequency dispersion means 11 uniformly supplies the heating chamber 2 from below. Then, the tray 10 is placed on a rail 12 provided on the side surface of the heating chamber for use.

用いた。As the high-frequency heating element 9, a ceramic high-frequency heating element 9 provided with a high-frequency heating film 8 made of a nitride and a boride is used, and as a receiving tray 10, corrugated irregularities are provided on the surface and a gap 13 is formed by aluminum plating. A saucer 10 having a fluorine coating on the surface of a steel plate and a black heat resistant coating on the back surface was used.

を付けることができた。When chicken thighs were used as the object to be heated and preheated for 10 minutes with the high-frequency heating element and the saucer put in, the upper heater 600W as the heating means 6 and the high-frequency 300W were simultaneously heated for 10 minutes. Both the front and back surfaces were heated moderately, and the front and back surfaces were particularly well-marked and the finish was good. The water reduction rate was 13%, which was reasonably juicy. Also, the inside was heated and the front and back could be browned without the trouble of turning the chicken thigh over.

考えられる。また、隙間が無いときに比べて、高周波が
受け皿１０の表側に回り込む量が少なくなったために鶏
ももの減水率が高くならず、良好な焦げ目が表裏につい
たと考えられる。This is because the provision of the gap 13 increases the distance between the high frequency absorption film 8 and the metal surface of the tray 10 to increase the electric field strength on the high frequency absorption film 8 and the high frequency absorption film 8 It is thought that this is due to the higher heat generation of. Further, it is considered that compared to the case where there is no gap, the amount of high-frequency waves circling to the front side of the saucer 10 was small, and therefore the water reduction rate of chickens did not increase, and good browning was formed on the front and back sides.

薄く、また、高周波が鶏ももに多く供給された結果、鶏
ももの減水率が２４％と高くなり、鶏ももが縮んで固く
なると共に、裏面に焦げ目が付きにくかった。When the surface of the saucer 10 is not provided with the wavy irregularities and the gaps 13 are not provided, the back surface is thin and the high frequency is supplied to the chicken thigh, resulting in reduced water content of the chicken thigh. The rate was as high as 24%, the chicken thighs shrank and became hard, and it was difficult for the back side to be charred.
【００３１】これは、電波吸収膜８と受け皿１０の金属
表面との距離が近いため高周波吸収膜８上での電界強度
が低くなり、高周波吸収膜８での発熱が低くなり、高周
波が受け皿１０の表側に回り込む量が多くなったために
鶏ももの減水率が高くなり、焦げ目が裏面に付きにくく
なったと考えられる。This is because the distance between the radio wave absorption film 8 and the metal surface of the saucer 10 is short, the electric field strength on the high frequency absorption film 8 is low, the heat generation in the high frequency absorption film 8 is low, and the high frequency wave is received by the saucer 10. It is considered that the water loss rate of chickens became higher because the amount of water that went around to the front side of the chicken increased, and it became difficult for the brown eyes to attach to the back surface.

０秒間加熱した場合で比較した。Further, the difference in effect between the case with and without the metal tray 10 and the difference between the effect with and without the gap 13 are compared by heating water with the high-frequency heating device 4. . 100 ml of water at 10 ° C with 1000W
Comparison was made in the case of heating for 0 seconds.
【００３３】金属製の受け皿が無い場合には、水温は
５．７℃上昇し、出力に換算すると３４２Ｗが水に供給
されいた。When there was no metal tray, the water temperature rose by 5.7 ° C., and 342 W was supplied to the water in terms of output.
【００３４】金属製の受け皿が有り、かつ、隙間が無い
場合には水温は４．７℃上昇し、出力に換算すると２８
２Ｗが水に供給されていた。When there is a metal tray and there is no gap, the water temperature rises by 4.7 ° C., which is 28 in terms of output.
2W was being supplied to the water.
【００３５】金属製の受け皿が有り、かつ、隙間がある
場合には、水温は３．０℃上昇し、出力に換算すると１
８０Ｗが水に供給されていた。If there is a metal tray and there is a gap, the water temperature rises by 3.0 ° C., which is 1 in terms of output.
80 W was being supplied to the water.
【００３６】一方、金属製の受け皿が無い場合には、高
周波発熱体の底面の温度は、２３℃から３０℃に７℃上
昇していた。On the other hand, when there was no metal tray, the temperature of the bottom surface of the high-frequency heating element was increased by 7 ° C from 23 ° C to 30 ° C.
【００３７】金属製の受け皿が有り、かつ、隙間が無い
場合には、高周波発熱体の底面の温度は、２３℃から２
５℃に２℃上昇していた。When there is a metal tray and there is no gap, the temperature of the bottom surface of the high-frequency heating element is from 23 ° C to 2 ° C.
It had risen by 2 ° C to 5 ° C.
【００３８】金属製の受け皿が有り、かつ、隙間がある
場合には、高周波発熱体の底面の温度は、２３℃から３
４℃に１１℃上昇していた。When there is a metal tray and there is a gap, the temperature of the bottom surface of the high-frequency heating element is from 23 ° C to 3 ° C.
It had risen by 11 ° C to 4 ° C.
【００３９】以上から、高周波発熱体のみを受け皿にし
て高周波加熱すると、金属製の受け皿がある場合よりも
多くの高周波が被加熱物に供給されることが分かる。From the above, it can be seen that when high frequency heating is performed using only the high frequency heating element as a pan, more high frequency is supplied to the object to be heated than when there is a metal pan.
【００４０】また、高周波発熱体の上に金属製の受け皿

なることが分かり、隙間がある場合よりも多くの高周波

の場合には、下面は焦げるが高周波が鶏ももに多く供給
されるので身縮みの原因になったと考えられる。Even when a metal tray is installed on the high-frequency heating element, it can be seen that the temperature of the high-frequency heating element has not risen if there is no gap, that is, it is difficult to heat the high-frequency heating element. It can be seen that more high frequency is supplied to the object to be heated than in some cases. In the case of chickens, this is considered to be the cause of shrinkage because the lower surface is scorched, but high frequencies are supplied to chickens.
【００４１】また、金属製の受け皿に隙間を設けること
により、隙間が無い場合よりも高周波が被加熱物に供給
量が少なくなることが分かる。これが、鶏ももが身縮み
せずに良好に加熱され、焦げ目が付いた原因であると考
えられる。Further, it can be seen that by providing a gap in the metal tray, the amount of high frequency supplied to the object to be heated is smaller than in the case where there is no gap. This is considered to be the reason why the chicken thigh was well heated without shrinking and was browned.
【００４２】なお、上記では、ヒータ加熱と高周波加熱
を同時に行ったが、別々に行っても、あるいは、同時と
別々を繰り返しても良い。In the above, the heater heating and the high frequency heating are performed at the same time, but they may be performed separately or may be performed simultaneously and separately.
【００４３】また、側面に電波の発信口がある場合と下
方に電波の発信口がある場合を比較すると、下方にある
場合の方が、より加熱むらが少なかった。Further, comparing the case where there is a radio wave transmission port on the side surface and the case where there is a radio wave transmission port below, there was less heating unevenness in the case below.
【００４４】レール１２としては、奥行き方向に長く設
置するほど、受け皿１０と側壁面との隙間が小さくな
り、下方より供給された高周波が受け皿１０の上方への
回り込みが小さくなり、被加熱物の下面の焦げがより付
きやすくなった。The longer the rail 12 is installed in the depth direction, the smaller the gap between the tray 10 and the side wall surface becomes, and the high frequency supplied from the lower side does not wrap around to the upper side of the tray 10 so that the object to be heated is reduced. The bottom surface is easier to burn.
【００４５】受け皿１０の配置および構成として、加熱

高周波波が受け皿の上方に回り込むことが少なくなり、
高周波発熱体へのマイクロ波の供給量が多くなり、被加
熱物の下面の焦げ目がより付きやすくなるという効果が
ある。The arrangement and structure of the tray 10 is such that the heating chamber is divided into an upper portion and a lower portion, and the outer shape of the tray is configured so that the gap between the heating chamber side wall surface and the door that closes the heating chamber is small. As a result, high-frequency waves supplied from below are less likely to wrap around above the pan,
This has the effect of increasing the amount of microwaves supplied to the high-frequency heating element and making it easier for the lower surface of the object to be heated to be burnt.
【００４６】なお、加熱手段６としては、管ヒータ、シ

The cooking device and the like do not hang on the high frequency dispersion device 11 and the like.
