As mentioned above, the length of pipeline 20 is long and crooked big, so even increase the internal circulating load of air in 29 pairs of cylinders of blower fan 9, also can not cause the suction of the water that injects dehumidifier 20 inside.Its result can increase as requested to the amount of air circulation in the cylinder 9, shortens drying time.
In addition, as mentioned above, the sectional area of pipeline 20 inside is maximum at the pars intermedia of air suction inlet 23 and air outlet 24, and this pars intermedia flow velocity that is flowing in that flows through air in the cylinder 9 in the pipeline 20 reduces, and so also can not cause the suction of the water of flow in pipes 20 inside.Therefore, also can further increase thus, further shorten drying time the amount of air circulation in the cylinder 9.
In addition, as mentioned above, blower fan 29 is with the state configuration of a side of the central portion on deflection bucket 7 tops, thus make blower fan 29 be configured in the low part of central portion (top) than the top of bucket 7, thus can suppress whole height.
And as mentioned above, the male member 25b towards insides of pipes because of recessed portion 25 being formed at pipeline 20 makes the water of flow in pipes 20 inside clash, disperse, so increase with the amount of contact of air in flowing through pipeline 20, effect on moisture extraction is improved.
Fig. 7 represents embodiments of the invention 2.This embodiment 2 is as follows with the difference of the foregoing description 1 (with reference to Fig. 5).That is, the inner section of pipeline 20 is amassed in air outlet 24 sides and is become maximum among this embodiment 2.Specifically, the sectional area of pipeline 20 inside is 12 near air suction inlet 23,000mm
2, it increases gradually, and 24 places are maximum at air outlet, are about 13,500mm
2
Its result, among the embodiment 2, airflow flowing is the slowest in air outlet 24 sides in pipeline 20.Its result among the embodiment 2, can not cause the suction of the water of flow in pipes 20 inside yet, can increase the air circulation air quantity in the cylinder 9, shortens drying time.
