【考案の詳細な説明】
本考案はヒータを備えた高周波加熱装置に関するもので
ある。[Detailed Description of the Invention] The present invention relates to a high frequency heating device equipped with a heater.
従来より、高周波加熱装置はマグネトロン等の高周波発
振器によって発振させた高周波を被加熱物に照射し、被
加熱物自身を発熱させ迅速に加熱する事が大きなメリッ
トであった。Conventionally, high-frequency heating devices have had the great advantage of irradiating a heated object with high-frequency waves oscillated by a high-frequency oscillator such as a magnetron, thereby causing the heated object itself to generate heat and quickly heating it.
又被加熱物自身を加熱させる為、焦げ目が付かず、再加
熱においては絶大なる効果を発揮している。In addition, since the object to be heated is heated itself, there is no browning, and it is extremely effective in reheating.
しかしながら最近では、家庭パン、ケーキ、クツキー等
の菓子作りが頻繁に行なわれるようになった事、又、ロ
ーストチキンや魚、肉、グラタン等の料理においても、
オーブンで加熱したような焦げ目が付かない為、非常に
見栄えば悪く何かもの足りないもので、特に魚、肉料理
では気持ちが悪くて食べる気がしなかったりする事があ
る。However, recently, home-made sweets such as bread, cakes, and kutskii have become more common, and dishes such as roast chicken, fish, meat, and gratin have become more popular.
Because it doesn't brown like it does when heated in an oven, it looks very unappealing and lacks something, and fish and meat dishes in particular can be so unpleasant that you don't feel like eating them.
そこで、最近では、焦げ目を付ける為に、高周波加熱装
置にヒータを組み込んだものが実施されるようになった
。Therefore, recently, in order to brown the food, high-frequency heating devices incorporating a heater have been put into practice.
又、この時、焦げ目を付ける事だけが目的でヒータを被
加熱物に近づける構造のものと、加熱室内の温度を高温
にして調理する本格的なオーブン料理が行なえるものと
がある。Also, at this time, there are those that have a structure in which the heater is brought close to the object to be heated for the sole purpose of browning, and those that allow full-fledged oven cooking in which the temperature inside the heating chamber is raised to a high temperature.
調理のレパートリや仕上がり具合等は、後者の方が格段
に良いのであるが高周波加熱装置の電気部品や、外筐等
が非常に高温となる為、断熱が難かしく、又、断熱材を
使用した場合には、大幅なコストアップとなり余り好ま
しくなかった。The latter method is much better in terms of cooking repertoire and quality of cooking, but the electric parts of the high-frequency heating device and the outer casing reach extremely high temperatures, making it difficult to insulate them, and it is difficult to insulate them, and it is difficult to insulate them. In some cases, this would result in a significant increase in cost, which was not very desirable.
そこで本考案は、金属板により断熱を行なう為非常に安
価に行なえ、且つ断熱効果の大きいもので、従来の高周
波加熱装置のイメージである、外筐が熱くなりにくいと
いうメリツl−をも有するものである。Therefore, the present invention uses a metal plate for insulation, so it can be done at a very low cost and has a large insulation effect.It also has the advantage that the outer casing does not get hot, which is the image of conventional high-frequency heating equipment. It is.
・以下本考案の一実施例を図面と共に説明する。- An embodiment of the present invention will be described below with reference to the drawings.
第1図は、従来の高周波加熱装置1の加熱室2の内部に
ヒータ3及び4を組み込み、オーブン料理も出来るよう
になったもので゛ある。FIG. 1 shows a conventional high-frequency heating device 1 in which heaters 3 and 4 are built into the heating chamber 2 to enable oven cooking.
第2図は、高周波加熱装置をオーブンとして使用した時
の熱の移動を矢印で示したものである。FIG. 2 shows the movement of heat using arrows when the high-frequency heating device is used as an oven.
この実施例は断熱材を使用していない場合で、図の矢印
で示すように、加熱室2及び機器本体の外筐5からの熱
の放散が激しいもので、その結果、加熱室内設定温度に
達する迄の加熱室内温度の立ち上がりが非常に遅くなる
ものである。In this example, no heat insulating material is used, and as shown by the arrow in the figure, heat dissipates rapidly from the heating chamber 2 and the outer casing 5 of the equipment body, and as a result, the set temperature of the heating chamber does not reach the set temperature. The rise in temperature within the heating chamber is extremely slow.
又、一度加熱室設定温度に達しても、保温能力が悪い為
非常に効率が悪く、時間当たりの電力消費量かばう大と
なるもので、使用者にとっては電気代がかさむ事になる
のである。Moreover, even once the temperature of the heating chamber reaches the set temperature, the efficiency is very low due to the poor heat retention ability, and the power consumption per hour is high, resulting in high electricity costs for the user.
又、加熱室2の温度が放散しやすいという事は、高周波
加熱装置の外筐5の温度が高温となり、使用者が触れて
、火傷を負ったりする危険性があった。Furthermore, the fact that the temperature in the heating chamber 2 is easily dissipated means that the temperature of the outer casing 5 of the high-frequency heating device becomes high enough to cause a risk of a user touching it and suffering from burns.
以上のような理由から断熱材が多用されているのである
が、高価なものである為、大幅なコストアップとなり、
その結果、矢張り、需要家がそのコストアップ分も負担
する破目になるので゛ある。For the reasons mentioned above, insulation materials are often used, but since they are expensive, the cost increases significantly.
As a result, the consumer ends up having to bear the cost increase as well.
そこで本考案では、第3図に示すように加熱室2を構成
する上板6のフランジ部7に接触させ、加熱室側壁8と
ほぼ平行に金属板9を設は加熱室側壁8と金属板9との
間に保温空間を形成したものである。Therefore, in the present invention, as shown in FIG. A heat insulating space is formed between the two.
この効果は、加熱室2よりの放熱を金属板9により阻止
し、加熱室の保温を目的としたものであるが、この構造
は加熱室後壁にも同等の効果が得られる。This effect is aimed at keeping the heating chamber warm by blocking heat radiation from the heating chamber 2 with the metal plate 9, but this structure also provides the same effect on the rear wall of the heating chamber.
なお第3図において、11は加熱室2に高周波を供給す
る高周波発振器、12は加熱室の側壁及び後壁と外筐と
で形成される空間の下部に設けられた高圧トランスで、
高周波発振器11の電源部品となるものである。In FIG. 3, 11 is a high-frequency oscillator that supplies high-frequency waves to the heating chamber 2, and 12 is a high-voltage transformer provided at the bottom of the space formed by the side and rear walls of the heating chamber and the outer casing.
This serves as a power supply component for the high frequency oscillator 11.
以上のように本考案によれば、非常に安価なうえ、その
効果は非常に大きく、時間当たりの電力消費量は極端に
低くなるものである。As described above, according to the present invention, it is not only very inexpensive, but also has a very large effect, and the power consumption per hour is extremely low.
又、保温能力を向上させている為、外筐5の特に10の
部分の温度が低くなる為、使用者にとっては、非常に有
益なものである。Furthermore, since the heat retention ability is improved, the temperature of the outer casing 5, especially at the part 10, is lowered, which is very beneficial for the user.
また高周波発振器に高圧を印加するトランスは従来から
底板に取付けられているが、トランスは非常に大きな漏
洩磁束を発生し、近傍に強磁性体があれば磁気振動の原
因となる。Furthermore, the transformer that applies high voltage to the high-frequency oscillator has conventionally been attached to the bottom plate, but the transformer generates a very large leakage magnetic flux, and if there is a ferromagnetic material nearby, it can cause magnetic vibrations.
これを非磁性体であるアルミ、銅、オーステナイト系ス
テンレス等で形成すれば非常に大きなコストアップとな
る。If this is made of non-magnetic material such as aluminum, copper, or austenitic stainless steel, the cost will increase significantly.
特に熱容量を小さくするためには断熱板を極薄金属板で
構成する必要があるが、一方で機械的強度が小さくなり
、ビビリ音等が発生しやすくなる。In particular, in order to reduce the heat capacity, it is necessary to construct the heat insulating plate from an extremely thin metal plate, but on the other hand, the mechanical strength is reduced, making it easy to generate chattering noises and the like.
そこで本考案は金属板の下端部が加熱室の底面まで達し
ない構成とすることにより、上記の問題点を解決できた
ものである。Therefore, the present invention solves the above-mentioned problems by configuring the metal plate so that the lower end does not reach the bottom of the heating chamber.
