I. Internal Structure of a Microwave Oven:

1. Cavity and Door Assembly:

• The microwave oven’s cavity houses the cooking chamber, while the door assembly contains the protective mesh and safety interlocks.
  • Within the Microwave oven Schematic, the cavity’s reflective surfaces are strategically positioned to aid in distributing microwaves evenly for cooking.

• Magnetron:

• Positioned at the heart of the microwave, the magnetron generates microwaves by converting electrical energy into radiofrequency radiation.

• Waveguide System:

• The waveguide directs microwaves from the magnetron to the cooking chamber, ensuring an efficient distribution of energy.

• Turntable and Stirrer:

• The turntable rotates to guarantee uniform heating, while the stirrer (in some models) disperses microwaves evenly for consistent cooking results.

• Control Panel and User Interface:

• The control panel houses the user interface, featuring buttons, a digital display, and sensors for programming and monitoring cooking parameters.
