Patent number: 7442119Abstract: Disclosed is an exhaust hood (10) comprising a drive unit (20) for generating an air flow, a control device or control circuit for controlling the drive unit (20), and a measurement section comprising a transmitter device (22) and a receiver device (24). The control device or control circuit is configured so as to control the drive unit (20) in accordance with a signal generated by the receiver device (24). The transmitter device (22) is provided with a laser module that is aimed directly at the receiver device (24). Said laser module generates a laser beam (25) which is deflected in accordance with the presence of cooking vapors such as steam. The respective deflection influences the signal generated by the receiver device (24) such that the signal allows the control device or control circuit to draw conclusions about the presence of cooking vapors such as steam or movements of air and thus automatically control the drive unit (20) as needed.Type: GrantFiled: April 18, 2007Date of Patent: October 28, 2008Assignee: E.G.O. Elektro-Geratebau GmbHInventor: Henry Fluhrer

Patent number: 7320636Abstract: An exhaust assembly is provided for expelling contaminated air from a building. The assembly includes a plenum, a fan assembly attached to the plenum, and a windband mounted on top of the fan assembly. The fan assembly is constructed of cylindrical outer and inner walls which define a drive chamber and surrounding annular space. A fan driven by a motor whose shaft extends downward from the drive chamber draws exhaust air from the plenum and blows it up through the annular space to a nozzle at the top of the fan assembly. The motor is pivotally mounted inside the assembly to provide access to the motor components when it is desired to perform inspection and maintenance.Type: GrantFiled: December 3, 2004Date of Patent: January 22, 2008Assignee: Greenheck Fan CorporationInventors: Michael Glenn Seliger, Terry Lee Hrdina, Scott James Koeppel
