Abstract

PURPOSE:To obtain the product of a title device having the performances such as quick rising in temperature of its electrically heated wire, superior heat exchange rate and small size with high safety efficiency by a method wherein both ends of a electrically heated wire with coil-shape is connectingly supported by holding fixtures made of the heat-resistant insulating material, and a heat source is formed by fixing said electrically heated wire to a enamelled metal cylinder. CONSTITUTION:A frame body 1 with U-shape cross section is formed of enamelled iron plate, a cylinder 9 is formed by jointing a similarly enamelled covering body 6 to a flange part 2 of said frame body 1. Holding fixtures 11 made of the heat-resistant insulating mateial are fixed to a cut and set up part 8 arranged on said covering body 6 at the location correspond to both side walls of the frame body 1, further, terminals 10 made of the stainless steel are penetrated through the holding fixtures 11 and fixed to said holding fixtures 11 with push nuts 12 made of stainless steel. Also, a coil-shape electrical heated wire 14 is connected between both terminals 10 inside of the cylinder 9. Thereby, the heat source for the hot-air generating device having the excellent heat exchange rate and the small size with high safety can be produced at a low cost due to its structure having the quick rising in temperature and the good surface contact with the air.

Description

【発明の詳細な説明】 本発明は熱風循環式オープン等に用いられる熱風発生装
置用の熱源に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat source for a hot air generator used in hot air circulation type openers and the like.

一般に熱風発生装置用の熱源としてなじみ深いのは、ヘ
アードライヤーであるが、このヘアードライヤーの熱風

ため、万一電熱線が断線しても感電等の配属をあまり必
要としない。Generally, a hair dryer is a familiar heat source for hot air generators, but since the temperature of the hot air from this hair dryer is at most 60 degrees, it is necessary to hold the coiled heating wire at a temperature of 1 mycorrhiza. Since a mica laminate is used and the main body of the dryer can also be made of a resin material, even if the heating wire breaks, there is no need to deal with electric shock or the like.

しかし熱風循環式オープンの場合は加熱室内の平均温度
が２５０°Ｃ前後となり、熱風そのものは３００°Ｃに
なるため、熱風循環式オープンの本体を樹脂材で構成し
たり、電熱線をマイカ積層板で保持することは不可能で
ある。However, in the case of a hot air circulation type open type, the average temperature inside the heating chamber is around 250°C, and the hot air itself is 300°C. It is impossible to hold it in

従って熱風循環式オープンには第３図ａ及び第４図ａに

図すはこのシーズヒータ３１を用いた熱風循環式オープ
ンの構成を示したものである。Therefore, a heat source as shown in FIGS. 3a and 4a was used for the hot air circulation type opening. The heat source shown in FIG. 3a is a sheathed heater 31 wound 1.5 times into a coil, and the figure shows a hot air circulation type open configuration using this sheathed heater 31.

この熱風循環式オープンの構成は、加熱室３２の上部中

。In this hot air circulation type open configuration, a 7-amp motor 33 and a 7-amp motor 34 are provided in the upper center of the heating chamber 32, and a fan 3
The sheathed heaters 3 and 1 are provided around the heater 3.

。As is well known, this sheathed heater 31 is equipped with a wire around the heating wire, and this magnesium is covered with an outer covering such as an insulating material, so there is no electrical leakage and the thermal and mechanical strength are stable. Therefore, the sheathed heater 31 can be directly fixed to the heating chamber wall, which is very convenient for handling.

しかし反面／−ズヒータ３１は高価であるとともに、外

ータ３１自体の温度上昇が遅く、その上外被の表面種も
小さいので風との熱交換が少なく、熱風発生装置用の熱
源としての熱効率は非常に悪いものであった。However, on the other hand, the 7-Z heater 31 is expensive, and the heat capacity of the jacket and magnesium is large, so the temperature of the 7-Z heater 31 itself rises slowly.Furthermore, the surface type of the jacket is small, making it difficult to exchange heat with the wind. Therefore, the thermal efficiency as a heat source for a hot air generator was very poor.

この熱源を改良したのが第４図ａであり、その構成は磁

、同図すはその側面図を示すものである。An improved version of this heat source is shown in FIG. The figure shows its side view.

一般に熱交換率をよくするには、全ての電熱線が開口部
（風の流入口）から見通せる位置に配置すればよい。Generally, to improve the heat exchange rate, all heating wires should be placed in a position where they can be seen from the opening (air inlet).

第５図は第４図ａに示す熱源を用いて構成しだ熱風循環
式オープンであるが、熱源を構成する磁器製の円筒３６
及び心棒３６の価格は、炉で一度に焼土げる数量によっ
て決定される。Fig. 5 shows a hot air circulation type open system constructed using the heat source shown in Fig. 4a.
The price of the mandrel 36 is determined by the quantity that can be fired at one time in the furnace.

従って大きな円筒は非常に高価となる。Large cylinders are therefore very expensive.

また価格以外にシーズヒータはどではないが、心棒３６

かも心棒３６に接する部分の電熱線１４の熱交換がされ
にくく、熱効率を低下させる原因となっている。Also, other than the price, there is nothing wrong with the sheathed heater, but the mandrel is 36
Since the heating wire 14 has the highest temperature, the temperature of the heating wire 14 increases, and it is difficult to exchange heat in the portion of the heating wire 14 in contact with the mandrel 36, which causes a decrease in thermal efficiency.

筒３６内部の空間利用率が非常に悪いため、円筒３５の
径が大きくなり、ひいては熱風循環式オープンの上部が
異状に大きくなるという欠点があった。As is clear from FIGS. 4a and 4b, it is not easy to mold the heating wire 14 into the metal rod 36 in the shape of a flower petal, and the space utilization inside the cylinder 36 is very poor. The problem was that the size of the hot air circulation type opening became large, and the top of the hot air circulation type open became abnormally large.
