Abstract
According to the present invention, a blower unit includes a centrifugal fan, a fan casing forming a scroll-shaped air passage and accommodating the centrifugal fan, and a partition wall for partitioning an interior of the fan casing into first and second air passages in which different kinds of airs flow, respectively, in the axial direction. The partition wall is molded integrally to the fan casing so as to extend linearly from the inner wall surface of the fan casing toward a radial inside of the fan. The fan casing includes two divided cases having a divided face in the axial direction. In this way, the number of divided cases can be as well as the number of steps of assembling the fan casing can be reduced so that the work efficiency for assembling the fan casing is improved.
