Samsung patents fan design with a gap between its outer rings
Samsung has been granted a patent for a centrifugal fan design used in home appliances. The fan features two outer rings, or shrouds, that surround the blades. Unlike typical designs, the outer ring is spaced away from the inner ring, creating a visible gap between them rather than overlapping.
In the filing’s own words
A centrifugal fan according to an embodiment includes: a plurality of blades arranged around a rotation axis of the centrifugal fan, and a first shroud and a second shroud located at ends of the plurality of blades. The second shroud surrounds the first shroud and is spaced apart from the first shroud. The second shroud does not overlap the first shroud in a direction parallel to the rotation axis of the centrifugal fan.
What exactly they claim (claim 1)
1. A centrifugal fan comprising: a plurality of blades arranged about a rotation axis of the centrifugal fan; and a first shroud and a second shroud located at ends of the plurality of blades, wherein the second shroud is adjacent to the first shroud and surrounds the first shroud, wherein the second shroud does not overlap the first shroud in a direction parallel to the rotation axis of the centrifugal fan, wherein, in a plan view, an inner edge of the second shroud is spaced radially outward from an outer edge of the first shroud, and wherein an inner diameter of the inner edge of the second shroud is larger than an outer diameter of the outer edge of the first shroud such that a radial gap is formed between the first shroud and the second shroud.
