Abstract

PURPOSE: To prevent dispersion of the miticidal effect by providing multiple lines of steam jet ports, and applying multiple steam exposures for one movement of a main body. CONSTITUTION: Water fed by a water feed pump 36 to the first vaporization chamber 29 and temperature-adjusted at the steam generation optimum temperature by a temperature regulator 31 is vaporized in the first vaporization chamber 29, and the steam is spouted into the second vaporization chamber 30 through a hole 28. The spouted steam is further heated and expanded in the second vaporization chamber 30, and it is spouted into the outside air from multiple lines of steam jet ports 32a, 32b. Piles 9 are pre-heated by the exposed steam from the steam jet ports 32 a of the first line, and the piles 9 are exposed to the steam from the steam jet ports 32b of the second line. A dense space of steam is formed between the steam jet ports 32a, 32b, steam is hardly leaked to the outside, and itis infiltrated into a carpet. The miticidal performance can be improved.
