Oven exhaust hood methods, devices, and systems
An exhaust device for convection or combi ovens captures exhaust from opening side-opening oven doors with minimal energy waste.
1. A method of controlling exhaust flow, comprising:
receiving at a digital controller at least one signal pertaining to a state of an oven, the at least one signal including an amount of time left on a timer indicating remaining time until shutoff of the oven;
increasing by the digital controller an exhaust flow at a first time responsively to the at least one signal indicating remaining time until shutoff of the oven; and
decreasing by the digital controller the exhaust flow at a later time responsively to at least another signal indicating that a door of the oven has been closed.
2. The method of claim 1 , wherein the at least one signal includes an image signal.
3. The method of claim 2 wherein the at least one signal includes a data signal from the oven.
4. The method of claim 1 wherein the at least one signal includes a data signal from the oven.
5. The method of claim 1 , wherein the at least one signal includes a signal from a proximity sensor.
6. The method of claim 2 , wherein the at least one signal includes a signal from a proximity sensor.
7. The method of claim 1 , wherein the at least another signal includes an image signal.
8. The method of claim 1 wherein the at least another signal includes a data signal from the oven.
9. The method of claim 1 wherein the controlling includes regulating both a fan speed and a damper in coordination.
10. The method of claim 2 wherein the controlling includes regulating both a fan speed and a damper in coordination.
11. The method of claim 3 wherein the controlling includes regulating both a fan speed and a damper in coordination.
12. The method of claim 4 wherein the controlling includes regulating both a fan speed and a damper in coordination.
