Definitions

  • ABSTRACT An improved door for microwave ovens having no exposed nut and bolt type means to retain the various components of such door together.
  • the door is so constructed that the method for taking the door apart is not readily apparent to the average microwave oven user.
  • Various components are mounted on the interior housing panel and various other components are mounted on the exterior housing panel. Then the interior housing panel and the exterior housing panel and their associated respective components are mounted together by concealed retaining means.
  • foodstuffs may be cooked within a microwave oven by electromagnetic wave energy radiating from a magnetron.
  • the conventional microwave oven has a rectangular, box-like cooking cavity in which foodstuffs may be placed for exposure to such electromagnetic wave energy.
  • the cooking cavity generally is constructed of six walls, one of the walls being the interior surface of the microwave oven door.
  • the door facilitates the insertion and the removal of the foodstuffs to and from the cooking cavity of the microwave oven. Any time a door is utilized to seal an opening, there is some clearance between the edges of the door and the abutting edges defining the opening, the width of the clearance being dependent upon the tolerance of the particular construction. 1
  • such a clearance provides a path for the escape of electromagnetic wave energy from the cavity of the microwave oven.
  • Excessive leakage of electromagnetic wave energy may be harmful to persons in close proximity of the microwave oven and may interfere with other communications systems.
  • the manufacturers of such ovens provide electromagnetic wave energy seals either in the door or within the surface abutting the door in the closed position.
  • microwave oven doors have been manufactured in the past, including doors which do not include a viewing area to allow one to observe the cooking of foodstuffs.
  • Practically all of the modern microwave ovens include a conventional RF screen through which one is able to observe the cooking of foodstuffs placed within the cavity of the microwave oven.
  • a pane of transparent material such as glass or plastic, is placed on either side of the RF screen, or the RF screen is sandwiched between two such panes of transparent material.
  • microwave oven door Over a period of continuous use of the microwave oven, moisture and food particles will adhere to the interior surface of the microwave oven door and may enter the internal areas of the door.
  • a typical fastidious housewife desires a spotless microwave oven and she will consistently clean the cavity of the microwave oven, including the interior surface of the microwave oven door.
  • she may call upon her husband to take the door apart in order that she may clean the internal areas of the door. Since the various components of prior microwave oven doors were held together by conventional exposed nut and bolt type means, the husband could successfully take apart the door with ordinary household tools, for example, a screw driver and/or a pair of pliers. The husband could usually reconstruct the microwave oven door without any visual damage thereto.
  • the present invention provides an improved door for microwave ovens having no exposed nut and bolt type means to retain the various components of .such door together.
  • the door is so constructed that it cannot be readily taken apart by the average microwave oven user without causing visual damage to one or more components of the door.
  • Various components are mounted on the interior housing panel and various other components are mounted on the exterior housing panel. Then the interior housing panel and the exterior housing panel and their associated respective components are mounted together by concealed retaining means.
