産業上の利用分野
本考案は加熱室内の温度を加熱手段および循環ファンに
より上昇させる、いわゆる熱風循環方式の電気オーブン
に関するものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric oven of a so-called hot air circulation type in which the temperature inside a heating chamber is raised by a heating means and a circulation fan.
従来例の構成とその問題点
加熱室内の空気を循環させると加熱室内の熱分布が均一
化されるとの発想のもとに各種熱風循環方式の加熱装置
が商品化されている。Conventional configurations and their problems Various hot air circulation type heating devices have been commercialized based on the idea that circulating air within the heating chamber will equalize the heat distribution within the heating chamber.
その中で加熱装置としてシーズヒータを装着した例を第
１〜２図で説明する。An example in which a sheathed heater is installed as a heating device will be described with reference to FIGS. 1 and 2.
本体１内に加熱室２があり、加熱室２の前面開口部には
開閉自在のドア３がある。A heating chamber 2 is provided within the main body 1, and a door 3 that can be opened and closed is provided at the front opening of the heating chamber 2.
加熱室２の後壁４に隣接して略隔室５が設けられ、前記
隔室５内には加熱室内の温度を上昇させる加熱手段６と
加熱室２と隔室５の空気を循環させるファン７とが装着
されている。A compartment 5 is provided adjacent to the rear wall 4 of the heating chamber 2, and within the compartment 5 are a heating means 6 for increasing the temperature in the heating chamber and a fan for circulating air between the heating chamber 2 and the compartment 5. 7 is installed.
したがってモータ８でファン７を回転させると加熱室後
壁４の中央部に設けた吸込口９から加熱室２内の空気を
隔室５内に吸込み、加熱手段６で加熱された空気が後壁
４の上下に設けた吹出口１０から加熱室内に吹出され矢
印の如く循環し、食品載置台１１上にのせられた被加熱
物１２が加熱調理される。Therefore, when the fan 7 is rotated by the motor 8, the air inside the heating chamber 2 is sucked into the compartment 5 through the suction port 9 provided at the center of the rear wall 4 of the heating chamber, and the air heated by the heating means 6 is transferred to the rear wall. The food is blown into the heating chamber from the air outlets 10 provided above and below the food holder 4 and circulates as shown by the arrow, so that the food to be heated 12 placed on the food table 11 is heated and cooked.
ここで前記加熱手段６としてシーズヒータを使用した場
合、ファン７の外周辺部に第２図に示す如く複数回円形
に巻き、シーズヒータ１３の端子部１４で取付金具１５
を固着し、取付金具１５に固着したビス１６で隔室壁１
７にナツトで装着されていた。When a sheathed heater is used as the heating means 6, it is wrapped around the outer periphery of the fan 7 several times in a circle as shown in FIG.
and the compartment wall 1 with screws 16 fixed to the mounting bracket 15.
It was installed by Natsuto in 7.
したがって、もしシーズヒータ１３内部で断線等が生じ
ヒータ線が外部の金属パイプに接触等が起ると加熱装置
本体の電位が給電部と同じ電位となり、もし人がふれる
と感電する危険性を有していた。Therefore, if a break occurs inside the sheathed heater 13 and the heater wire comes into contact with an external metal pipe, the potential of the heating device body becomes the same potential as the power supply, and there is a risk of electric shock if a person touches it. Was.
なお、ヒータを複数回巻いて構成したものは、特開昭５
０−２４４７６号公報に、ヒータをガイシで固定した構
成のものは特開昭４９−４７５６９号公報にそれぞれ記
載されているが、いずれも安全性の点で不十分であった
。In addition, a heater constructed by winding it multiple times is disclosed in Japanese Patent Application Laid-open No. 5
0-24476 and JP-A-49-47569 disclose a structure in which the heater is fixed with an insulator, but both of them are insufficient in terms of safety.
考案の目的
上記従来の欠点を解消するために本考案は、シーズヒー
タを２回巻いた部分を手で圧縮してガイシの溝部に挿入
し、シーズヒータを復元力で、シーズヒータをガイシの
溝部に保持させることにより、安全性の高い加熱装置を
構成するものである。Purpose of the invention In order to eliminate the above-mentioned drawbacks of the conventional technology, the present invention was developed by manually compressing the twice-wound part of the sheathed heater and inserting it into the groove of the insulator. By holding the temperature at 1000 mL, a highly safe heating device is constructed.
考案の構成
上記目的を達成するために本考案は、本体内に被加熱物
を調理する加熱室と、前記加熱室の側壁部あるいは後壁
部に隣接して加熱手段を収納する隔室と、前記隔室内に
加熱手段と隔室との空気を循環させるファンを設け、前

したものである。Structure of the Invention In order to achieve the above object, the present invention includes: a heating chamber for cooking an object to be heated in a main body; a compartment housing a heating means adjacent to a side wall or a rear wall of the heating chamber; A fan for circulating air between a heating means and the compartment is provided in the compartment, and the heating means is composed of a sheathed heater that is wound twice on the outer periphery of the fan, and the sheathed heater has a portion that is wound twice. It is compressed and inserted into the groove of the insulator and held by the restoring force of the sheathed heater.
実施例の説明
そこで本考案は簡単な構成で上記欠点を解決するもので
あり、以下その実施例を第３．４．５図で説明する。DESCRIPTION OF EMBODIMENTS The present invention solves the above-mentioned drawbacks with a simple structure, and an embodiment thereof will be described below with reference to FIG. 3.4.5.
まずシーズヒータ１３の端部１４を隔室壁１７に設けた
穴１８に貫通させる。First, the end portion 14 of the sheathed heater 13 is passed through the hole 18 provided in the compartment wall 17.
その後ファン７の近傍でシーズヒータを第５図の点線１
９の如く手で圧縮してガイシ２０に挿入する。Then, connect the sheathed heater near the fan 7 with the dotted line 1 in Figure 5.
Compress it by hand and insert it into the insulator 20 as shown in 9.
圧縮している手をはなすとシーズヒータは元通りとなリ
ガイシ２０より抜けない。When you let go of the compressed hand, the sheathed heater returns to its original state and cannot be pulled out from the rig 20.
この状態でガイシ２０を隔室壁１７にビス２１ナツト２
２で固定する。In this state, attach the insulator 20 to the compartment wall 17 with screws 21 and nuts 2.
Fix it at 2.
一方隔室に設けた穴１８を通した端子部１４の上からガ
イシ２３をシーズヒータに通し、前記穴に挿入する。On the other hand, the insulator 23 is passed through the sheathed heater from above the terminal portion 14 through the hole 18 provided in the compartment, and inserted into the hole.
その後第４図に示すブツシュナツト２４をシーズヒータ
に貫通させヒータを固定する。Thereafter, a bushing nut 24 shown in FIG. 4 is passed through the sheathed heater to fix the heater.
なおブツシュナツト２４の穴径ｌはシーズヒータ１３の
外径よりも小さくしているとともに弾性を有する金属板
で作られているのでシーズヒータの端子部１４より圧入
するとブツシュナツト２４の斜線部２５がそのシーズヒ
ータ１３から抜けることはない。Note that the hole diameter l of the bushing nut 24 is smaller than the outer diameter of the sheathed heater 13 and is made of an elastic metal plate, so when the bushing nut 24 is press-fitted from the terminal part 14 of the sheathed heater, the diagonal line part 25 of the bushing nut 24 will close to the sheath. It does not come out of the heater 13.
考案の効果
以上説明したように本考案によれば次のような効果が期
待できる。Effects of the invention As explained above, according to the invention, the following effects can be expected.
１）本考案ではシーズヒータをガイシで加熱装置本体と
簡単に絶縁できるため、万一シーズヒータ内部で断線し
ヒータ線が外側パイプにふれても漏電および感電するこ
とがなく、きわめて安全である。1) In the present invention, the sheathed heater can be easily insulated from the heating device main body using insulators, so even if a wire breaks inside the sheathed heater and the heater wire touches the outside pipe, there will be no leakage or electric shock, making it extremely safe.
２）従来例の場合、シーズヒータに取付金具を固着した
り、取付金具にビスを固着したりしなければならないが
、この固着方法としてカシメあるいはロー付等をしなけ
ればならない。2) In the case of the conventional example, it is necessary to secure the mounting bracket to the sheathed heater or to secure screws to the mounting bracket, but this fixing method requires caulking, brazing, etc.
したがって作業性が悪いが、本考案ではこの様な所がな
く作業性が向上するとともに、経済的である。Therefore, workability is poor, but the present invention does not have this problem, improves workability, and is economical.
３）従来例では１点支持であるが、本考案では２点支持
以上となり、シーズヒータとファン、加熱室後壁、隔室
壁等の距離が確実にとれ、シーズヒータの熱を効率よく
熱風に変更することができる。3) In the conventional example, it is supported at one point, but in the present invention, it is supported at two or more points, and the distance between the sheathed heater and the fan, the rear wall of the heating chamber, the partition wall, etc. can be ensured, and the heat of the sheathed heater can be efficiently transferred to hot air. can be changed to .
特にシーズヒータが高温になった時膨張するが、そのた
めにファンとシーズヒータとの距離を多くとらなければ
ならず熱変換効率が悪かったが、本考案ではこのような
ことはない。In particular, the sheathed heater expands when it reaches a high temperature, which requires a large distance between the fan and the sheathed heater, resulting in poor heat conversion efficiency, but this does not occur with the present invention.
