- the rib 56 forms a water reservoir between the inner rib 51, the outer rib 52 and the rib 56. Condensation in the gap 55 dew condensation water is present in the water reservoir, and due to the small amount of water, it will eventually be easily evaporated. Further, after the cold air of the outdoor 2 contacts the heat insulating material 35, the flow comes into contact with the inner rib 51 in the upper and lower directions, and then flows into the room 1, and at this time, the temperature of the cold air passes through the gap 55 and is not transmitted to the outer rib 52. Therefore, it is prevented from forming dew condensation water on the outer surface of the outer rib 52 due to the temperature drop of the outer rib 52.

- the structure is mounted on the ventilator body 5. Further, on the inner side of the mask frame 14, that is, on the side of the wind tunnel portion 6, a sealing sponge 143 for blocking a gap 142 between the filter holder 141 and the ventilator body 5 is provided, and the sealing sponge 143 is a sealing structure.
- the filter holder 141 Since the filter holder 141 is engaged with the ventilator body 5, there is a certain gap 142 between the filter holder 141 and the ventilator body 5, so when the mask frame 14 is attached to the ventilator body 5
- the ventilating fan When the ventilating fan is in operation, the cold air sucked into the room 1 may be blown into the mask frame 14 through the gap 142, so that the upper side and the left and right sides of the mask frame 14 form dew condensation water, and a sealing sponge 143 is provided on the inner side of the mask frame 14.
- the sealing sponge 143 on the inner side of the mask frame 14 overlaps with the gap 142 between the filter holder 141 and the ventilator body 5, that is, the seal is used.
- the sponge 143 blocks the gap 142, and the sealing sponge 143 is deformed.
- the sealing sponge 143 functions to block wind and heat, so that no dew condensation water is generated here.
- the gap 142 between the filter holder 141 and the ventilator body 5 is blocked by the sealing sponge 143 to provide a sealing function, and the mask frame 14 can be prevented from forming dew condensation water.
- a wind guiding knot is further provided on the ventilating device body 5.
- the air guiding structure 144 is located at abutment of the ventilating device body 5 and the filter holder 141.
- the air guiding structure 144 is a supply from the ventilating device body 5.
- a passage through which the opening 146 into which the engagement piece 145 of the filter holder 141 is inserted is extended toward the air tube portion 6 side. Through the air guiding structure 144, cold air is blown along the air guiding structure 144 toward the wall covered by the ventilator body 5.
- the sealing sponge 143 that shields the gap 142 between the filter holder 141 and the ventilator body 5 is provided inside the mask frame 14, the wind may pass through the ventilator body due to the tight seal.
- the opening 146 for inserting the engaging piece 145 of the filter holder 141 on the fifth side causes air leakage at the side, so that cold air is directly blown on the side of the mask frame 14, resulting in dew condensation on the side of the mask frame 14.
