Abstract
An automated range hood includes a controller that selects a fan speed for one or more ventilation assemblies by identifying a minimum number of pixels that satisfy a threshold. The controller automatically turns on one or more light sources to illuminate a surface under the range hood when motion is detected or when the one or more ventilation assemblies are in use.
Claims14
An automated range hood for ventilating a cooking surface, the automated range hood comprising:
- a hood housing;
- a ventilation assembly mounted in the hood housing, the ventilation assembly including:
- an electric motor;
- and
- a fan driven by the electric motor to ventilate the cooking surface;
- a thermal camera measuring temperature values for a plurality of pixels in an array covering the cooking surface, wherein the array is segmented into a first portion under a first side of the hood housing, a second portion under a second side of the hood housing, and a third portion under a central portion overlapping the first and second portions;
- and
- a controller including:
- at least one processing device;
- and
- at least one memory device storing software instructions that, when executed by the at least one processing device, cause the controller to:
- select a fan speed from a plurality of fan speeds for the electric motor to drive the fan, the fan speed selected by identifying a highest temperature threshold from a plurality of temperature thresholds satisfied by a minimum number of pixels in the array, wherein a first fan speed is selected from the plurality of fan speeds by identifying a highest temperature threshold from the plurality of temperature thresholds satisfied by the minimum number of pixels in the first and third portions of the array, wherein the first fan speed is associated with a first ventilation assembly.
9 more elements
A controller for a range hood, the controller comprising:
- at least one processing device;
- and
- at least one memory device storing software instructions that, when executed by the at least one processing device, cause the controller to:
- receive temperature values from a thermal camera, the temperature values being captured for a plurality of pixels in an array segmented into one or more portions, wherein the array is segmented into a first portion under a first side of the range hood, a second portion under a second side of the range hood, and a third portion under a central portion of the range hood overlapping the first and second portions;
- and
- select a fan speed from a plurality of fan speeds for a ventilation assembly, the fan speed selected by identifying a highest temperature threshold from a plurality of temperature thresholds satisfied by a minimum number of pixels in the array, wherein a first fan speed is selected from the plurality of fan speeds by identifying a highest temperature threshold from the plurality of temperature thresholds satisfied by the minimum number of pixels in the first and third portions of the array, wherein the first fan speed is associated with a first ventilation assembly.
