Patent number: 11976842Abstract: A combined ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and a connector assembly. In an installed position, the system is installed above a ceiling of a room of building structure (e.g., a residence or workplace) to provide ventilation for the room. The system couples a light fixture to ventilation assembly below the ceiling. In the installed position, an air flow cavity is defined between the light fixture and the ceiling, where the cavity allows for air flow around the light fixture and into the ventilation assembly for eventual exhaust beyond the room in which the system is installed. The cavity includes a first critical distance that is sized according to operating parameters of a blower of the ventilation assembly to provide an adequate flow rate of intake air and to provide acceptable sound levels during operation of the system.Type: GrantFiled: September 20, 2021Date of Patent: May 7, 2024Assignee: Broan-NuTone LLCInventors: Richard R. Sinur, Ryan A. Revers

Patent number: 11703247Abstract: A ventilation system with automatic flow balancing derived from a neural network to consistently achieve a desired flow rate for inlet flow and/or outlet flow in various operating environments to optimize system performance. The system includes a ventilation device that includes an exhaust blower assembly with a blower motor and a control circuit having a mathematical equation that determines an estimated exhaust blower flow based upon select inputs. The ventilation device also includes a supply blower assembly with a blower motor and control circuit having a mathematical equation that determines an estimated supply blower flow based upon select inputs. When the estimated exhaust blower flow is different than an exhaust flow set point, the exhaust control circuit selectively alters power supplied to the exhaust motor. When the estimated supply blower flow is different than a supply flow set point, the supply control circuit selectively alters power supplied to the supply motor.Type: GrantFiled: October 13, 2021Date of Patent: July 18, 2023Assignee: Broan-NuTone LLCInventor: Simon Blanchard

Patent number: 11300307Abstract: A damper control assembly includes a damper body movable between a first threshold position and a second threshold position. A motor is operably connected to the damper body, wherein the motor drives the damper between the first threshold position to determine an open position and the second threshold position to determine a closed position. A controller is operably connected to the motor and has a stall detection module that detects a first rotor-lock condition when the motor drives the damper body to the first threshold position and a second rotor-lock condition when the motor drives the damper body to the second threshold position. The controller includes a memory module for storing the first and second threshold positions for use by the controller. The damper control assembly is calibrated to drive the damper body within an operating range having the open and closed positions and that is less extensive than a mechanical range defined by the first and second threshold positions.Type: GrantFiled: January 8, 2019Date of Patent: April 12, 2022Assignee: Broan-NuTone LLCInventors: Stephane Michaud, Frederic Bazin, Simon Blanchard
