Abstract
An adjusting and tuning arrangement is provided in a microwave oven to adjust the energy distribution to various areas of the oven cavity such as defined areas or the area of a sensor assembly on a tray inserted in the oven and also to balance the distribution of energy between the load articles on the tray and the sensor assembly or between various load articles. Two electrically conductive planar elements are positioned inside and project into the cavity to accomplish the tuning. The planar elements are arranged one above the other at predetermined angular orientations and are also each independently rotatable about one edge.
Claims14
In a system for heating articles by supplying electromagnetic energy to the articles to be heated which are carried by a tray placed within a cavity defined in a heating structure of the system,
- means for adjusting the distribution of energy supplied to particular areas of the cavity comprising a first generally planar electrically conductive member positioned in the cavity and near a boundary of the cavity and being movable such that a first edge is rotatable about a second opposite edge.
Apparatus for adjusting the distribution of energy in an electromagnetic heating oven having a cavity in which items to be heating are placed comprising a first generally planar electrically conductive member positioned in said cavity and near a boundary wall of said cavity and being movable such that a first edge is rotatable about a second opposite edge.
Apparatus for tuning the distribution of energy in an electromagnetic heating oven having a cavity in which items to be heated are placed comprising a first generally planar electrically conductive member positioned in said cavity and near a boundary wall of said cavity, said first planar element oriented at a predetermined angle from the reference plane perpendicular to the boundary wall and at a predetermined height above the cavity floor.
