Title:
CENTRIFUGAL BLOWER
Document Type and Number:
Japanese Patent JP2020016233
Kind Code:
A
Abstract:
To expand a range capable of maintaining the separation performance of two airflows in a relative positional relationship between a separation cylinder and a separation plate in an axial direction, and to expand a range capable of maintaining the separation performance of the two airflows in a relative positional relationship between a partitioning plate and the separation plate in the axial direction.SOLUTION: A centrifugal blower comprises a centrifugal fan, a fan casing and a separation cylinder 18. The separation cylinder 18 separates an airflow progressing toward the centrifugal fan to two airflows. The centrifugal fan has a separation plate 13 for blowing out the two airflows from the centrifugal fan in a state of separating the two airflows which are separated by the separation cylinder 18. The fan casing has a partitioning plate 15 for suppressing the mixture of the two airflows which are separated by the separation cylinder 18 and the separation plate 13. A height H1 of an inside end face 131 of the separation plate 13 is higher than a height H3 of a separation cylinder end face 181 of the separation cylinder 18. A height H2 of an outside end face 132 of the separation plate 13 is higher than a height H4 of a partitioning plate end face 151 of the partitioning plate 15.SELECTED DRAWING: Figure 2
