Waveguide assembly for an RF oven

An oven comprising:

• a cooking chamber configured to receive a food product, the cooking chamber being defined at least in part by a top wall, a first sidewall and a second sidewall;
• and
• a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components, the solid state electronic components including power amplifier electronics configured to provide the RF energy into the cooking chamber via a launcher assembly operably coupled to the cooking chamber via a waveguide assembly;
• wherein the waveguide assembly includes a waveguide extending along at least one of the first sidewall or the second sidewall to provide the RF energy into the cooking chamber through a radiation opening provided at the at least one of the first sidewall or the second sidewall,
• wherein the launcher assembly includes a launcher disposed proximate to a first end of the waveguide and the radiation opening is disposed proximate to a second end of the waveguide,
• wherein the waveguide is defined by a back plate that lies adjacent to the at least one of the first sidewall or the second sidewall, and a front plate extending away from the back plate,
• wherein the front plate is defined by a front face extending substantially parallel to the back plate, a top face extending between the front face and the back plate substantially perpendicular to both the front face and the back plate, two side faces opposing each other on opposite lateral sides of the front face extending between the front face and the back plate, and a bottom face,
• wherein the bottom wall is disposed at an angle relative to the front face to extend between the front face and the back plate, and
• wherein the radiation opening is disposed in the back plate of the waveguide assembly such that a portion of the bottom wall and a portion of an interior of the front face are visible through the radiation opening, the radiation opening being offset away from an intersection of the bottom face and the back plate.
