をつなぐ通風管を備えたことを特徴とするものである。In order to achieve the above object, the microwave heating device of the present invention prevents the microwave from leaking from the inlet / outlet of the object to be heated of the oven that continuously heats the object to be heated conveyed by the belt conveyor. In the microwave heating device provided with a choke, a choke provided at the outlet is used as an internal cavity structure and a hot air generator for sending hot air into the cavity, and a ventilation pipe connecting the hot air generator and the choke. It is characterized by having.
第１図は本考案の一実施例を示す。 FIG. 1 shows an embodiment of the present invention.
図において第５図の符号と同一の符号は同一または相当
するものを示し、12は熱風発生器、13は通風管、14はダ
クト、15は内部空洞構造のチョークである。In the figure, the same reference numerals as those in FIG. 5 designate the same or corresponding ones, 12 is a hot air generator, 13 is a ventilation pipe, 14 is a duct, and 15 is a choke having an internal cavity structure.
熱風発生器12で発生した熱風は、通風管13、ダクト14を
経てチョーク15の空洞内を流れてチョーク15の温度を上
昇させる。そして、熱風はチョーク15の先端から吹き出
し、被加熱物10が発生する蒸気の上昇を押える。The hot air generated by the hot air generator 12 flows through the ventilation pipe 13 and the duct 14 into the cavity of the choke 15 to raise the temperature of the choke 15. Then, the hot air blows out from the tip of the choke 15 and suppresses the rise of steam generated by the object to be heated 10.

は、チョーク15の先端から吹き出る熱風に押えられて分
散し、チョーク15表面に達する蒸気が少なくなる。チョ
ーク15表面に当たった蒸気も、チョーク15表面の温度が
高いために、表面で結露することがない。Therefore, the steam generated by the object to be heated 10 passing through the outlet 32 is pressed and dispersed by the hot air blown from the tip of the choke 15, and the steam reaching the surface of the choke 15 is reduced. The steam hitting the surface of the chalk 15 also does not condense on the surface because the temperature of the surface of the chalk 15 is high.
チョーク15は、ダクト14に電気的に確実に連結された状
態に取付けられていなければならない。The choke 15 must be attached to the duct 14 such that it is electrically connected.
第２図（ａ），（ｂ）はチョーク15の取付け構造の例を
示す。2 (a) and 2 (b) show an example of the attachment structure of the choke 15. As shown in FIG.

ることを防止することもできる。FIG. 3 shows an example in which the direction of the hole at the tip of the choke 15 is changed. The hole at the tip of the choke 15 is inclined toward the belt 8 to push the steam generated by the object to be heated 10 into the oven 3 and prevent the steam that causes dew condensation from being dispersed to the choke side. You can also

に効果的に防止することができる。As described above, according to the present invention, it is possible to prevent dew condensation on the surface of the chalk provided at the outlet of the oven, and to prevent water droplets from dropping on the product and impairing the quality of the product. . In addition, by sloping the direction of the hole at the tip of the choke, it is possible to push the steam generated from the object to be heated into the oven and prevent the steam from flowing into the choke side, which makes the occurrence of dew condensation even more effective. Can be prevented.
