様化のニーズに応じられないという問題点もあった。Problems to be Solved by the Invention However, in such an infrared heater, the filament coil must be inserted into a bent glass tube, so it is difficult to insert the filament coil 9 into the glass tube 8 (
In addition, since both ends of the glass tube 8 are close to each other, it is difficult to seal them, and the cost of a bent glass tube is higher than that of a straight glass tube (and therefore the cost of an infrared heater is high). In addition, such glass tubes are limited in shape and size, and therefore cannot meet diversification needs.

にヒータ取付は用の口金６が装着されている。As shown in FIG. 1, the infrared heater according to the embodiment of the present invention is
Made of transparent, opaque or colored opaque quartz glass,
Bent part 3 bent at multiple locations (bending angle θ=60°
), a filament coil 2 made of tungsten wire, molybdenum wire, etc., having an outer diameter somewhat smaller than the inner diameter of the glass tube, is placed along the tube axis in a symmetrical glass tube 1 made of argon gas, etc. Enclosed with inert gas. The glass tube 1 has a circular cross section at the straight portion 7, but has an elliptical cross section at the bent portion 3. The thickness of the glass on the outside 1b of the bent portion 3 is thinner than that on the inside 1a. In addition, the filament coil 2 has a non-circular coil element and a continuous coil element, and in the straight part 7 of the glass tube 1, as shown in FIG. They are provided along the tube axis direction in point contact.Furthermore, at the bent portion 3 of the glass tube 1 of the filament coil 2, the inner side 1a and the outer side (llllb) of the glass tube 1 are bent by the bending process. The width is narrowed,
It is sandwiched between the inner side 1a and the outer side 1b and is fixed in contact with the inner wall surface of the glass tube 1. As a result, during the bending process of the glass tube 1, the filament coil 2 serves to prevent the glass tube 1 from becoming depressed and to minimize deformation of the glass tube 1. The filament coil 2 is connected to an external lead wire 4 led out of the glass tube via metal foil (not shown) connected to both ends thereof. A lead &115 is connected to the external lead wire 4. Further, both end portions of the glass tube 1 where metal foil etc. are located are flatly sealed, and caps 6 for attaching a heater are attached to both end portions.
暖房用ヒータとしては、通常、外径９〜１１＋ｓの白色

う利点もある。As the heater, a white opaque quartz glass tube or a red colored opaque quartz glass tube with an outer diameter of 9 to 11+s is usually used. Opaque quartz glass tubes do not allow the heated filament coil to be seen directly, have the effect of softening the shine on the tube surface, and also have the advantage of being cheaper than transparent quartz glass tubes.
赤着色石英ガスラ管は、ヒータの発光が赤（暖かさが強

る。First, a filament coil and inert gas are sealed inside the glass tube using the same manufacturing machine and manufacturing method as a conventional straight tube infrared heater, and then both ends of the glass tube are sealed, and the outside is sealed. Connect the lead wires and attach the caps to both ends of the glass tube.Next, heat the center of the glass tube with a gas burner to soften it, and when the glass tube is in a softened state, bend it. A bent part is provided.Second and third bent parts are provided one after another in the glass tube using the same method.These bending methods include the irradiation method of the gas burner, the timing of bending, the sealing pressure inside the glass tube, etc. is an important element.

。また、ガラス管１内に封入する不活性ガスの封入ガス
圧は常温で０．４５〜０．７５気圧の範囲が望ましい。That is, unless the entire bent portion is heated uniformly and the glass tube is not bent when it is at an appropriate temperature, distortion will remain in the bent portion and the cross-sectional shape of the glass tube at the bent portion will be significantly deformed. Further, the gas pressure of the inert gas sealed in the glass tube 1 is preferably in the range of 0.45 to 0.75 atm at room temperature.

熱時間が長くなる程大きく、また同時に折曲げ加工する
箇所が多い程太き（なる。In other words, this inert gas has the function of suppressing the evaporation of tungsten or molybdenum in the filament coil 2, and if the sealed gas pressure is too low, the evaporation will increase (the blackening of the glass tube will progress, and the infrared heater will The life of the quartz glass tube is short (the outer diameter of the quartz glass tube is 9 to 111 mm, the power consumption is 20 mm).
As a result of testing 0 to 600W kotatsu and stove heaters, it was found that if the filled gas pressure was set to 45 atm or higher at room temperature, there would be little blackening of the inner wall surface of the glass tube during the rated life, and there would be no practical problem. became clear. Next, when bending the glass tube, it is necessary to heat the portion of the glass tube to be bent quite strongly with a gas burner, which increases the pressure inside the glass tube. The rate at which this pressure increases increases as the heating time increases, and the greater the number of parts that are simultaneously bent.
したがって、ガラス管の折曲げ加工時に折曲部において
ガラス管を膨らませないためにはガラス管内の封入ガス
圧を低く設定しておく必要がある。Therefore, in order to prevent the glass tube from being bulged at the bent portion during bending of the glass tube, it is necessary to set the gas pressure in the glass tube low.

曲げ加工が行える。As a result of making infrared heaters with various filling gas pressures using ordinary heating heaters and testing them with different bending processing conditions,
It has been found that if the pressure of the filled gas is 0.75 atm or less at room temperature, bending can be easily performed at each location even if the heating time is slightly longer. Furthermore, if the glass tube is partially cooled with cold water or liquid nitrogen, bending can be performed at up to three locations at the same time.
なお、折曲部３は３箇所程度が最も加工しやすいが、こ
れより多（することは可能である。Note that it is easiest to process the bending portions 3 at about three locations, but it is possible to have more than three locations.

It is preferable to set it as above. On the other hand, if the wall thickness of the glass tube is too large, bending becomes difficult. Therefore, the wall thickness of the glass tube used in this infrared heater before processing is 0.

変形が大きくなる。Further, as a result of various experiments, the difference between the inner diameter of the glass tube 1 and the maximum diameter of the filament coil 2 was desirably in the range of 0.8 to 2.2 M from the viewpoint of workability and appearance. That is, if the difference between the two is too small, the workability of inserting the filament coil 2 into the glass tube 1 will be poor, while if it is too large, the deformation of the glass tube 1 during the bending process will become large. .

。Note that the glass tube may be bent before the lead wire and cap are attached. Moreover, as a heating means for the glass tube, in addition to a gas burner, a high frequency wave or a laser can be used.

性が向上し、製造コストも安（なる。As described in detail, the infrared heater of the present invention has a filament coil fixed in contact with the inner wall surface of the glass tube at the plurality of bent portions, so unlike the conventional infrared heater, the filament coil is not bent into a circular shape or the like beforehand. There is no need to use straight glass tubes (straight glass tubes can be used, so the cost of glass tubes is low. Also, the shape and size of the glass tube can be changed quite freely, so it can be adjusted to suit your needs. In addition, according to the infrared heater manufacturing method of the present invention, since a normal straight glass tube is used, conventional manufacturing machinery can be used as is, and Compared to the manufacturing method of round infrared heaters, workability is improved and manufacturing costs are lower.
