Abstract
An air circulation system includes an inlet filter support structure, a first side filter and a second side filter. The air circulation system is for an oven that has a cooking chamber configured to receive a food product and a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components. The air circulation system is configured to provide air for cooling the solid state electronic components. The inlet filter support structure enables cooling air for cooling the solid state electronic components to be drawn therein prior to circulation by a cooling fan. The first side filter is supported by the inlet filter support structure. The first side filter is disposed below one of the sidewalls and disposed at an angle relative to the one of the sidewalls. The second side filter is supported by the inlet filter support structure. The second side filter is disposed below an opposing one of the sidewalls and disposed at the angle relative to the opposing one of the sidewalls.
