産業上の利用分野
本発明は一般家庭において、主Ｋ調理用Ｋ使用される電
熱ユニットに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric heating unit used for cooking in general households.
従来の技術
従来よシ、一般家庭で使用される調理用の電熱ユニット
としては、陶器の上Ｋ螺旋状Ｋ巻いた電熱線を配設した
電気とんろやシーズヒータを渦巻状に巻きユニット化し
た電気レンジなどがある。Conventional technology Traditionally, electric heating units for cooking used in general households include electric hob and sheathed heaters equipped with spirally wound heating wires on a ceramic surface. There is an electric range.
これら以外に、欧米では、螺旋状に巻いた電熱線を断熱
材に設けた溝に配設し、この上にセラミック・ガラス板
を置き、セラミック・ガラス板を加熱面とするスムーズ
トップと呼ばれる電熱ユニットなどが広く使用されてい
る（特公昭６２−２９４５４号公報など）。In addition to these methods, in Europe and the United States, there is an electric heating system called smooth top, in which a spirally wound heating wire is placed in a groove in the insulation material, and a ceramic or glass plate is placed on top of this. units are widely used (Japanese Patent Publication No. 62-29454, etc.).
しかし、日本Ｋおいては、陶器を使用した電気こんろが
価格的に安価であると共Ｋ、スムーズトップなどの電熱
ユニットなどに比較して、熱効率に優れるため、いまだ
、根強い需要がある。However, in Japan, electric stoves made of ceramic are still in strong demand because they are inexpensive and have superior thermal efficiency compared to electric heating units such as Smooth Top.
しかし、昔ながらの陶器を使用した電気こんろは、電熱
線が、外部に直接露出しているため、危険であったり調
理物の内容物が、吹きこぼれ電熱線の断線寿命を著しく
短かくするなどいろいろな欠点があった。However, with traditional ceramic stoves, the heating wires are directly exposed to the outside, which can be dangerous, and the contents of the cooking material can boil over and significantly shorten the lifespan of the heating wires. There was a drawback.
さらＫ、陶器の熱容量が大きいため、重いと共に、なか
なか冷めにくく、使用後、すぐに移動したり、また収納
することが出来ず、使い勝手の面においても欠点があっ
た。Furthermore, since ceramics have a large heat capacity, they are heavy, difficult to cool down, and cannot be moved or stored immediately after use, which also has drawbacks in terms of ease of use.
このため、本発明者らは、すでに金属板からなる天板と

断熱材からなる断熱基盤と、この断熱基盤を収納する金
属板からなる収納ケースとからなり、前記天板の被加熱
物側には放射層が、また電熱線側には絶縁層が形成され
ていることを特徴とする電熱ユニットを提案している。For this reason, the present inventors have already developed a structure that consists mainly of silica-alumina fibers, which has a top plate made of a metal plate, a spirally wound military heating wire, and a groove in which the heating wire is arranged in a meandering manner. It consists of a heat insulating base made of a heat insulating material and a storage case made of a metal plate that houses this heat insulating base, and a radiation layer is formed on the side of the object to be heated of the top plate, and an insulating layer is formed on the side of the heating wire. We are proposing an electric heating unit that is characterized by:
しかしながら断熱基盤としてシリカ−アルミナ繊維を主
成分とする断熱材は一般的に結合材としてシリカゾルを
使用しているため吸湿性に富み、多湿雰囲気中に放置さ
れると電熱ユニットの電気特性の著しい低下が生じ、実
使用上における問題があった。However, since insulation materials mainly composed of silica-alumina fibers as insulation bases generally use silica sol as a binding material, they are highly hygroscopic, and if left in a humid atmosphere, the electrical properties of the electric heating unit will deteriorate significantly. This caused problems in actual use.
しかし、この間題Ｋついては結合材として従来のシリカ
ゾルに代えて吸湿性に劣るアルミナゾ〜系を用いること
により著しく改善することが可能となった。However, this problem K can be significantly improved by using an aluminazo-based binder, which has poor hygroscopicity, in place of the conventional silica sol.
発明が解決しようとする課題
上述したように結合材として従来のシリカゾｐに代えて
アルミナゾルを用いることにより耐湿特性は著しく改善
することは可能となったが、とのように結合材をアルミ
ナゾルに代えてもシリカアルミナ繊維を主成分とする断
熱材の吸水性を防止することが出来ない。Problems to be Solved by the Invention As mentioned above, it has become possible to significantly improve moisture resistance by using alumina sol instead of the conventional silica sol as a binder. However, it is not possible to prevent the water absorption of a heat insulating material whose main component is silica-alumina fiber.
即ち、異常使用状態において、たとえば水をかけたり、
水中に没するようなことをされると、断熱材は著しく吸
水し、電気特性は損なわれるという問題はいまだ残って
おり、このような断熱材を使用する電熱ユニットの大き
な課題であった。In other words, under abnormal usage conditions, for example, water may be poured on the
The problem still remains that when submerged in water, the insulation material absorbs water significantly and its electrical properties are impaired, which has been a major issue for electric heating units that use such insulation materials.
本発明は上述した課題を解決するもので、水をかけられ
ても優れた電気特性を示す電熱ユニットを提供しようと
するものである。The present invention solves the above-mentioned problems, and aims to provide an electric heating unit that exhibits excellent electrical characteristics even when exposed to water.

ものである。Means for Solving the Problems In order to solve the above problems, the present invention provides a top plate made of a metal plate, a spirally wound heating wire, and a silica glass plate having a groove in which the heating wire is arranged in a spiral shape. A heat insulating base made of a heat insulating material mainly composed of alumina fibers, a storage case made of a metal plate that houses the heat insulating base, the heat insulating base on which the heating wire is arranged, the top plate and the storage case are insulated. This is achieved by constructing each of the insulators.
作 用
本発明で示すように金属板からなる天板および収納ケー

により、電熱ユニットＫ万がー、水がかけられたりして
断熱基盤が吸水［２、電電特性が損なわれても、絶縁碍
′：ｆ：Ｋより天板および収納ケースとは絶縁されるた
め電気特性は損なわれることがない。Function As shown in the present invention, by insulating the top plate and storage case made of metal plates and the heat insulating base located inside these with an insulator that has extremely low water absorption and excellent electrical properties, an electric heating unit can be produced. K-Man, the insulation base will absorb water if water is splashed on it [2. Even if the electrical characteristics are impaired, the electrical characteristics will be impaired because it is insulated from the top plate and storage case due to insulation strength':f:K. It never happens.
尚、絶縁碍子としては、吸水をより一層抑えるために釉
薬を施したり、より高温で焼結させ気孔率を少なくした
ものが望ましい。It is desirable that the insulator be glazed or sintered at a higher temperature to reduce porosity in order to further suppress water absorption.
また、絶縁碍子は、あまり、多く使用すれば、重盾か増
大し熱容量も大きくなり、断熱基盤としてシリカｉ７ｋ
ミナ繊維を主成分とする断熱材を用いるメリットが損な
われるので必要最小限Ｋとどめるのがよい。In addition, if too many insulators are used, the heavy shielding will increase and the heat capacity will also increase.
Since the advantage of using a heat insulating material whose main component is Mina fiber is lost, it is better to keep K to the necessary minimum.
