Air circulation device
First Claim
1. An air circulation device comprising a hollow housing, an air blower mounted in said housing and including an impeller and an impeller casing having an air inlet and outlet, said hollow housing including an air inlet and air outlet with the air outlet from the casing being connected to the air outlet in the housing for discharging pressurized air from the housing, the inlet for the hollow housing being spaced from the casing to enable inlet air to completely enclose the blower for entry into the air inlet of the impeller casing and means adjustably supporting said hollow housing, said hollow housing including a curved external surface with the air inlet being defined by a slot extending around a substantial portion of the curved surface of the housing, said air inlet for the housing being formed by a downwardly opening arcuate slot along a portion of the hollow housing opposite the air outlet, said hollow housing being substantially spherical in configuration, said supporting means for the housing including an annular member engaging and supporting the lower surface portion of the hollow housing and enabling the hollow housing to be pivoted about a vertical axis and a horizontal axis to direct the air outlet in a desired direction.

Abstract
An air circulation device and more particularly an air circulation device having a dome shaped housing enclosing all moving components of an air blower which incorporates a squirrel cage impeller in a casing provided with an air inlet and discharge. A supporting structure enables adjustment of the dome shaped housing for discharging air in a desired direction. The air blower discharge communicates with and is connected with a peripherally extending outlet in the housing in the form of a plurality of slots with a transition member sealingly connected to the blower discharge and air outlet. The housing also includes an air inlet with a removable filter so that inlet air completely surrounds the blower in the housing. The upper portion of the housing may be provided with an illumination device and several embodiments of the housing and support structure are disclosed.
