Specifically, as shown in fig. 11, a plurality of supporting members 136 are equidistantly connected between two adjacent dehumidifying layers 138 along the winding direction of the scroll casing 124; the support 136 may support the volute casing 124, so that the volute casing 124 is not easy to deform, as shown in fig. 12, the support 136 includes a comb plate 137, two ends of the comb plate 137 are fixed with the dehumidifying layer 138, and two ends of the comb plate 137 are comb teeth ends 134; in the process of flowing along the inner side of the volute casing 124, the wet air flow can only pass through the comb teeth ends 134 when encountering the comb plate 137, and can have an extrusion and dispersion effect on the wet air flow, so that the wet air flow is in more sufficient contact with the dehumidifying layer 138, and the dehumidifying effect is improved.

Example 3:

the dehumidifying module 103 further includes a dehumidifying particle type dehumidifying structure 109 in the prior art as shown in fig. 3, the dehumidifying particle type dehumidifying structure 109 includes a placement groove and dehumidifying particles located inside the placement groove, a heating element is disposed inside the placement groove for heating the dehumidifying particles and removing moisture inside the dehumidifying particles, so that the dehumidifying particles can be reused, the placement groove is located on the upper side of the scroll dehumidifying structure, and a dehumidifying module 123 adopting the scroll dehumidifying structure is not shown in fig. 3; the air flow dehumidified by the volute dehumidification structure passes through the placing groove, and dehumidification particles in the placing groove are used for carrying out moisture absorption treatment on the air flow again, so that the dehumidification effect is further improved.
