CONSTITUTION:The upper part of a heating apparatus partitioned by a bottom plate 7 is a heating chamber 9, while the lower part is an power section 10 in order to house electric parts. High-frequency waves are supplied to the heating chamber 9 from a high-frequency generator such as a magnetron 11 provided in the electric section 10, passing through a wave guide 12 provided to the back side of a back panel 2. A door 14 of front-opening type covers the opening 8 of a front panel, and its open/close fulcrum 15 is positioned in the lower part of a front panel 1. The door 14 has a cutout opening 22 in the position where an operating board 21 is positioned, and the above-mentioned open/close fulcrums 15 and arms 17 are housed in the right and left post parts 14a on both sides of a cutout 22. With such an arrangement, a timer and other parts on the operating board 21 fitted to the front panel can be operated with the door 14 being closed.

ものであ゛る。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the structure of a high frequency heating device such as a microwave oven.

従来例の構成とその問題点 電子レンジ等の加熱調理器具は台所の調理場新道に置い
て使用されることが多いが、住宅事情と調理関連器具の
多様化から、これら調理器具の載置スペースは大きな制
約を受けている。Conventional configuration and its problems Heating cooking utensils such as microwave ovens are often placed in the cooking area of the kitchen, but due to housing conditions and the diversification of cooking-related utensils, it is difficult to place these cooking utensils in the kitchen. Space is severely constrained.

従来の電子レンジ等の加熱調理器具は、加熱室とその右
方に操作部を備えた形態のものが一般的であって、操作
部は高周波発生装置その他の電気部品を収納する電気室
の前面にあって、加熱時間を設定するタイマや加熱室内
温度を設定するダイヤル等のつまみが配置されている。Conventional heating cooking appliances such as microwave ovens are generally equipped with a heating chamber and an operation section on the right side of the heating chamber.The operation section is located at the front of the electrical chamber that houses the high-frequency generator and other electrical components. There are knobs such as a timer for setting the heating time and a dial for setting the heating chamber temperature.

これらの操作部が本体の右方に位置している理由は、使
用者の大半が通常布ききであるという前提に立つもので
あって、台所における種々の器具の配置を考えたもので
はない。即ち、これらの加熱調理器の置き場所によって
は、加熱室前面をおおう扉は左開き、右開きのいずれの
場合も必要であって、扉の開閉方向によっては操作部も
左方にあった方が操作しやすい場合もあるが、現実には
左操作部の器具というものはない。また扉が前開きの構
造のものでも、右側操作部が通例である。The reason why these operation parts are located on the right side of the main body is based on the assumption that most users usually wear cloth, and does not take into account the arrangement of various appliances in the kitchen. In other words, depending on the location of these heating cookers, the door that covers the front of the heating chamber may need to open to the left or the right, and depending on the opening/closing direction of the door, the door that covers the front of the heating chamber may need to be located on the left. Although it may be easier to operate, in reality there is no such thing as a device with a left-hand control section. Even if the door opens from the front, the operating section is usually located on the right side.

このような構成の加熱調理器具は、置き場所によっては
極めて操作しにくいという欠点があるとともに、設置ス
ペースを広く必要とするという不具合があった。A heating cooking appliance having such a configuration has the disadvantage that it is extremely difficult to operate depending on the location where it is placed, and also requires a large installation space.

最近、操作部を本体の上部または゛下部に配置して、上
記欠点を軽減しているものも見受けられるようになった
。ただこの場合にも１、加熱室を構成する箱体の外側に
外郭材を被せるといういわば二重構造のものが主である
。即ち、加熱室と外郭材との間にはある程度の空隙を有
していて、断熱材や種々の機構部品や接続用電線等の取
付場所として利用されてはいるものの、この空隙のため
に本体外形寸法に対する加熱室有効容積を相対的に小さ
くしているという欠点が残っている。Recently, some devices have been seen in which the operation section is located at the top or bottom of the main body to alleviate the above-mentioned drawbacks. However, in this case as well, 1. A so-called double structure is mainly used, in which an outer shell material is placed over the outside of the box that constitutes the heating chamber. In other words, there is a certain amount of space between the heating chamber and the outer shell material, and although it is used as a place for installing heat insulating material, various mechanical parts, and connecting wires, this space makes it difficult for the main body to The drawback remains that the effective volume of the heating chamber is relatively small relative to the external dimensions.

設置スペースの制約で本体外形を定めた場合、その外形
寸法にいっばいの大きさの加熱室容積を確保できれば、
被加熱物の収容量がそれだけふえ、ひいては加熱時間の
短縮につながるであろうし、また従来の加熱室と同容積
のままで上記空隙のないものができれば、それだけ設置
スペースの削減に役立つという利点があるが、現実には
設置スペース制約によって本体外形寸法を決められると
、加熱室容積は比例的に小さくなり、加熱室容積を基準
にすると、本体外形が大きくなり、設置面積を大きなも
のにせざるを得ないという欠点があった。When determining the external shape of the main unit due to installation space constraints, if you can secure a heating chamber volume that is as large as the external dimensions,
This will increase the storage capacity of the object to be heated, which in turn will lead to a reduction in heating time.Also, if a heating chamber with the same volume as a conventional heating chamber but without the above-mentioned voids can be created, it will help to reduce the installation space. However, in reality, if the external dimensions of the main unit are determined by installation space constraints, the heating chamber volume will be proportionally smaller, and if the heating chamber volume is used as a standard, the external size of the main unit will become larger, forcing the installation area to be larger. There was a drawback that it was not possible.

発明の目的 本発明は上記従来の欠点を解消し、操作部は器具の置き
場所に関係なく操作しやすく、しかも加熱室の大きさに
くらべて外形寸法を極めて小さくできる高周波加熱装置
の構成を提供することを目的とする。OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides a configuration of a high-frequency heating device in which the operating section is easy to operate regardless of the location where the device is placed, and whose external dimensions are extremely small compared to the size of the heating chamber. The purpose is to

There is an electrical room 10, and the front side of the electrical room 10 is the operation part, so it is easy to operate regardless of where the device is placed, and there is no inconvenience in opening and closing the door 14. Due to the single-layer structure, the volume of the heating chamber can be extremely large compared to the external dimensions, and the metal material used is also reduced, making it possible to reduce weight. By arranging various electrical components at the bottom, the center of gravity of the main body is low, making it lightweight. Despite this, it has the advantage of being able to be installed stably.
