When the situation of dew generation at the exhaust port of the decorative member is searched, it is found that dew is generated on the lower surface of the upper plate of the exhaust port of the decorative member. This is because warm air containing water vapor in the cleaning chamber passes below the upper plate of the exhaust port, and outside air with a lower temperature drifts above it, which causes the upper plate of the exhaust port to rise. This is because the water vapor contained in the air of the cleaning chamber passing therethrough is condensed on the lower surface of the upper plate portion of the exhaust port by being cooled.

Therefore, by providing a heat insulator on the upper plate portion of the exhaust port of the decorative member, it is possible to prevent the low temperature of the outside air from affecting the upper plate portion of the exhaust port of the decorative member, and to prevent dew condensation on the lower surface of the upper plate portion. Can be prevented. Further, in this case, in particular, in the case where the heat insulating body is formed of foamed synthetic resin and the decorative member is molded by inserting the heat insulating body, the mounting of the heat insulating body to the upper plate portion of the exhaust port of the decorative member is performed by the mold of the decorative member. Can be done at the same time by molding.

Further, even if the heat insulating material is provided as synthetic resin fibers on the exhaust port upper plate portion of the decoration member, the heat insulating body can be easily attached to the exhaust member upper plate portion of the decoration member.
In addition, in the case where the exhaust member upper plate portion of the decorative member is configured by fitting the heat insulator, not only the heat insulating member can be easily mounted, but also the influence of the low temperature of the outside air on the decorative member exhaust port upper plate portion.
