【考案の詳細な説明】
(イ) 産業上の利用分野
本考案は特に電気コタツに最適なヒータユニツ
ト装置に関する。[Detailed description of the invention] (a) Industrial application field The present invention particularly relates to a heater unit device suitable for electric kotatsu.
(ロ) 従来の技術
最近の電気コタツは所謂家具調として年中使用
されるようになつた。(b) Conventional technology Recently, electric kotatsu (kotatsu) have come to be used all year round as so-called furniture-style kotatsu.
しかしながら、ヒータユニツトの厚みが大きく
例えば夏季等においては邪魔になる欠点があるた
め、各部の温度上昇を抑えつつ如何に薄くするか
が大きな課題となつた。 However, since the thickness of the heater unit is large and it becomes a nuisance, for example in the summer, it has become a major problem to find a way to make the heater unit thinner while suppressing the rise in temperature of each part.
ところで、ヒータユニツトのヒータは該ヒータ
を取り付ける取付板との間に、できる限りの空間
を設け各部（取付板）の温度上昇を抑える必要が
あるが、前述の空間を大きく設定すれば逆にヒー
タユニツトの厚みを大きくすることとなつた。 By the way, it is necessary to provide as much space as possible between the heater of the heater unit and the mounting plate on which the heater is attached to suppress the temperature rise of each part (mounting plate), but if the above-mentioned space is set large, the heater It was decided to increase the thickness of the unit.

口金とは別個の専用の支持脚が必要となり部品点

された孔から熱気が漏れ取付板の上面に設けた化
粧板の温度を高くする原因となつた。 Therefore, the fixing structure of the end portion of the heater has a large effect on the thinning of the heater unit described above. This is because as the distance between the end of the heater and the mounting plate increases, the space between the center of the heater and the mounting plate increases, making the unit thicker, and conversely, as the distance decreases, the space decreases, making the unit thinner. However, there is a drawback that the temperature rise of the mounting plate becomes large. Therefore, when fixing the end of the heater, use a special mounting bracket (elastic wire) so that there is an appropriate space between the heater and the mounting plate, as in Japanese Utility Model Application Publication No. 55-35423. It was on. However, such a fixing structure requires a dedicated support leg that is separate from the base, which increases the number of parts and causes poor workability.Furthermore, it is difficult to fix the heater end and the support leg, and to fix the support leg and the mounting plate. This caused the temperature of the mounting plate to change due to variations in the support legs, causing rattling, and hot air leaking from the holes formed in the mounting plate, increasing the temperature of the decorative board provided on the top surface of the mounting plate.

る。(g) Effects of the invention As described above, in the present invention, the mounting brackets fixed to both ends of the tube-shaped heater are directly fixed to the protrusion of the rectangular mounting plate. In addition, since the height with respect to the bulging portion is accurately set during molding, there is no need for dedicated support legs, and assembly and workability are improved. Also,
As mentioned above, since support legs are not required, the number of fixed parts is reduced, and the cause of wobbling at the end of the heater can be eliminated. Particularly in the case of a heater using a thin tube, by directly attaching and fixing the mounting bracket at the end of the heater to the protruding part of the mounting plate, there is a gap between the heater and the protruding part of the mounting plate at the same time as the heater is fixed. Since a uniform air gap is formed, the range of the temperature rise of the mounting plate can be accurately known at the time of design, and the size of the air gap can be set to the minimum, making it possible to make the heater unit thinner. I can do it. Further, although the mounting plate becomes high in temperature due to radiant heat from the heater transmitted through the gap, the temperature of the frame body is shielded by a heat insulating plate provided on the upper surface of the mounting plate and is prevented from reaching a high temperature. Furthermore, since the lead wires of the heater are introduced into the space formed by the protrusion and the heat insulating plate, the space becomes larger, wiring work becomes easier, and the lead wires can be arranged in a concentrated manner.
