The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, the workshop structure using hot air to dehumidify is arranged in a workshop 1, the workshop 1 includes a first working floor 11 and a second working floor 12 arranged above the first working floor 11, an air compressor room 13 and/or a vacuum pump room 14 is arranged in the first working floor 11, the upper part of the air compressor room 13 and/or the vacuum pump room 14 is communicated with the second working floor 12 through a ventilation duct 2, one end of the ventilation duct 2 located at the air compressor room 13 and/or the vacuum pump room 14 is transversely arranged at the top of the air compressor room 13 and/or the vacuum pump room 14 and is provided with a plurality of air inlets 21 with downward openings, the other end of the ventilation duct 2 is transversely arranged at the top of the second working floor 12 and is provided with a plurality of air outlets 22 with upward openings, the middle section of the ventilation duct 2 is vertically arranged in the second working floor 12, a plurality of air outlets 15 communicated with the outside are arranged above the side part of the second working floor 12, a plurality of air inlets 16 communicated with the outside are formed below the side part of the second working floor 12, and heat radiating ports 17 communicated with the outside are formed below the side part of the air compressor room 13 and/or the vacuum pump room 14. By utilizing the chimney effect, after a certain height difference is generated, the density of hot air is small, and the hot air naturally rises under the action of buoyancy, so that a natural air duct is formed. The inside more heat that produces of air compressor machine room 13 and/or vacuum pump room 14, under the influence of chimney effect, hot-air carries to the top of second working floor 12 along air pipe 2, wherein places net splenium and/or rewinding machine in the second working floor 12, and the steam that its produced rises, nevertheless is difficult for condensing under the influence of the hot-air that air pipe 2 carried, and then discharges from gas vent 15, has reduced the condition that workshop 1 top wet.

Specifically, the top of the second working floor 12 is a sloping roof 3 made of flame-retardant color steel plates, the sloping roof 3 comprises sloping plates 31 with two sides sloping downwards, and a support frame mechanism 4 is arranged between the sloping roof 3 and the side part of the second working floor 12. Adopt the abat-vent 3, can derive the rainwater along swash plate 31 during the rainfall, the upper end is protruding simultaneously, and the hot-air can be followed the space between the swash plate 31 and discharged in a large number, reduces workshop 1 inside temperature.

In the deep position, a gap is reserved between the upper ends of the inclined plates 31 of the sloping roof 3, a top cap 32 covering the upper ends of the inclined plates is arranged at the top of the sloping roof 3, and a gap is reserved between the top cap 32 and the inclined plates 31. The top cap 32 covers the gap between the upper ends of the inclined plates 31, so that ventilation is ensured, and rainwater is prevented from leaking from the gap when raining.

Further, an air extracting fan 5 is provided in the air outlet 15. If the exhaust air in the second working floor 12 is not smooth or the internal temperature is high, the exhaust fan 5 is turned on to form convection by cooperating with the air inlet 16, thereby accelerating the air flow.
