本発明は電気ホツトプレ・一ト、電気鍋等の電熱器に関
し、特に熱効率の良い電熱器を提供しようとするもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electric heaters such as electric hotplates and electric pots, and particularly aims to provide an electric heater with good thermal efficiency.
従来、電気こんろの上にのせる磁器製鋼、磁器製プレー
ト等があつたが、電気こんろの電熱線とこれらの鍋、プ
レート等の間には必ず空間が存在するため、熱効率が悪
く、鍋、プレート等の温度上昇に時間がかかつた。Traditionally, there were porcelain steel and porcelain plates that were placed on top of electric stoves, but because there was always a space between the electric stove's heating wire and these pots, plates, etc., the thermal efficiency was poor, It took a long time for the temperature of the pot, plate, etc. to rise.
本発明は電熱線と容器との間の空間を無くすることによ
り上記従来の電熱器の欠点を解消するもので以下に本発
明の実施例について添付図面とともに説明する。The present invention eliminates the above-mentioned drawbacks of the conventional electric heater by eliminating the space between the heating wire and the container.Examples of the present invention will be described below with reference to the accompanying drawings.

By doing so, the heating wire 4 is fixed to the container 1.

た裏板である。Reference numeral 6 denotes a back plate that is engaged with a hook 7 formed on the periphery of the back surface of the container 1.
８は裏板６に取付けられた脚である。8 is a leg attached to the back plate 6.
次に、上述した電熱線４の埋設について第２図どともに
詳細に説明する。Next, burying the heating wire 4 mentioned above will be explained in detail with reference to FIG. 2.

溝３に少し埋め、Ｕ字状溝形成部材９で押圧し、第２図
口に示すようにＵ字状溝を形成する。First, as shown in FIG. 2A, the groove 3 is slightly filled with an insulating material 5 made of a mixture of, for example, 92% magnesia powder of 50 to 250 mesh and 8% silicon powder of 50 mesh or less. It is pressed with the groove forming member 9 to form a U-shaped groove as shown in the opening in FIG.

１を加熱するので容器１の熱的均一性を得ることができ
、またシリコン樹脂により電熱線４を容器１に固定する
ことができ、容 −易に電熱線４が取り外されることが
ない。When the heating wire 4 is placed along this U-shaped groove and heated to a temperature that melts the silicone resin, the molten silicone resin adheres thinly to the surface of the magnesia powder, becomes an adhesive, and hardens the magnesia powder. It also adheres to the wall of groove 3,
A heating wire 4 is fixed to the container 1. Thereafter, the heating wire 4 is further covered with the same type of insulating material as above and heated in the same manner as above. In the electric heater configured as described above, due to the presence of the magnesia powder, the heating wire 4 does not locally contact the container 1 and heat it, and the container 1 is heated uniformly over the entire length of the heating wire 4. Thermal uniformity of the container 1 can be obtained, and the heating wire 4 can be fixed to the container 1 with the silicone resin, so that the heating wire 4 is not easily removed.

の取り外れを防｛５できる電熱器が得られる〇As is clear from the above explanation, according to the present invention, there is no space between the container and the heating wire, so thermal efficiency is extremely high, and the insulating material used to embed the heating wire in the groove of the container contains magnesia and silicone resin. As a result, the container can be heated uniformly over the entire length of the heating wire, eliminating thermal unevenness in the container, and the heating wire can be fixed to the container to prevent the heating wire from coming off. Can be done〇
