Microwave Oven
What is Microwave Oven
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to vibrate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm (1–1.5 inches) of a homogeneous, high-water-content food item.
Advantages of Microwave Oven
Easy and Quick Reheating: The reheating process becomes a breeze with a microwave oven. Modern microwave ovens are smart and sense the level of cooking so that they do not overcook the food while reheating. You can also remain assured that the flavours in your food will remain intact after the reheating process is done.
Cleaning is Easy: Most microwaves use steam cleaning technology so that you do not have to spend hours trying to clean the gritty oil off the interiors. Therefore, you need not worry that the oil and dirt will cause any harm to the appliance.
Defrost Easily: Do you have frozen meat or veggies in the fridge that need to be cooked as soon as possible? You cannot cook frozen food, but your microwave brings these items to room temperature in minutes.
Cook with Confidence: Do not worry if you have never cooked before, or if you are just getting your feet wet. Everyone was a beginner once, and passion is enough to help you sail through the process. Additionally, microwave ovens aid you in your cooking efforts.
Energy Conservation: Modern microwaves are smart devices that use optimum power while heating or cooking your food. Firstly, it needs to do so to make sure the food does not burn. Secondly, its sensors let it know when it has reached the optimum temperature for a particular stage in cooking.
Safety: These appliances come with safety features for kids, so you need not worry about anyone getting hurt due to the appliance. To know more how to efficiently used your oven check this logic Oven manuals.

Consider the material and design of the microwave's exterior and interior. Stainless steel exteriors are popular for their durability and easy cleaning. Non-stick or ceramic interiors are convenient for cleaning spills and splatters.
Inverter Technology
Inverter microwaves use advanced technology to control power levels more precisely, resulting in more even and consistent cooking.
Budget
Determine your budget and explore options within that range. Microwaves are available in various price points, so you can find one that suits your needs and budget.
How Do You Use a Microwave
Read the owners' manual
Because every microwave contains different features and instructions, it is important to start by consulting your owner's manual. Your manual will provide general setup instructions as well as information regarding your microwave's settings and features.
Plug the microwave in
When plugging your microwave in, make sure to plug it into a grounded three-prong outlet. You shouldn't use an extension cord or adapter, and do not remove the ground plug. If the power supply cord is too short, consult an expert for outlet installation.
Set up turntable
As the part of the microwave upon which you place your food, the turntable is also an internal component you must set up yourself. Take your turntable and place it over the support and rollers, locking it into the hub. When the microwave operates, the hub will turn the turntable, but if the microwave is not spinning, follow these tips to resolve the issue.
Put food in a microwave-safe dish
To heat up food in a microwave, you must first make sure it is in a microwave-safe dish. If your dish has a microwave-safe lid, leave it on loosely to reduce splatter while also allowing steam to escape, then place the dish in the center of the turntable. Remember to read up on what you can and can't heat up in a microwave. And learn more about how to troubleshoot a microwave that's not heating properly.
Choose setting
Using your microwave to its fullest potential begins with choosing the right setting. Depending on your model, you will have a variety of settings available, typically including: Cook, reheat, defrost, melt and more. You can also usually select settings that will alter the power level (100% is the default; lower levels can be used for defrosting, reheating and more). Your microwave's wattage determines the max cooking power level.
Start microwave
After selecting your settings, touch the number keypads to set the length of time to cook your food. When the stop time is reached, the microwave will shut off automatically and the display will indicate that your cooking is complete. There will also be an accompanying noise with select models.
Microwave maintenance and cleaning
Like your other kitchen appliances, maintaining your microwave can help keep it in good working condition. For example, if you have an over-the-range filter, be sure to routinely change your filters to help clear the air in your kitchen. Additionally, cleaning your microwave is a crucial practice to help prevent that all-too-common burnt smell.
What Are the Parts of a Microwave
1. Turntable
The turntable is the round plate in the cooking cavity that rotates to help cook food evenly. Make sure the turntable is always securely in place before placing meals on it and using your microwave. If your microwave isn't spinning, check out this guide for solutions.
2. Magnetron
The magnetron produces the actual microwaves that reflect off the cooking cavity walls and flow through the turntable and cookware to the food. These waves interact with the food to produce heat and friction, which cooks your meals.
3. Voltage transformer
Since most electrical outlets use about 120 volts of electricity, a voltage transformer converts this into a higher voltage for fast heating and cooking. Most microwaves require 3,000 to 4,000 volts to function properly.
4. Waveguide and waveguide cover
The waveguide directs the flow and transports the actual microwaves to the cooking cavity.
5. Cooling fan
A cooling fan keeps your microwave cool, and it automatically kicks on when you are using your appliance. In some over-the-range microwaves, this fan may also automatically cycle on and off to keep the microwave cool if you are using the cooktop below. These types of microwaves also have a separate vent fan that helps to remove moisture and odors from the cooktop below it.
6. Cooking cavity
The cooking cavity is the compartment inside your microwave where you heat, defrost and cook meals. Regularly cleaning the interior of your microwave is key in order to keep it functioning optimally. Whirlpool® microwaves with a CleanRelease® non-stick interior allow for quick cleanups with the simple wipe of a damp cloth.
7. Power cord
No matter the type of microwave you have, the power cord gives it the ability to cook, re-heat, defrost and more. Most microwaves will need a grounded 3-prong outlet with a 120 volt and 15 or 20-amp electrical supply, like in this over-the-range microwave from Whirlpool brand. Refer to your owner's manual for model-specific requirements.
8. Control panel
A microwave control panel is the exterior display that has buttons for using your microwave, like timed cooking, defrosting and convenient preset options for heating pizza, popcorn, frozen entrees and more.
9. Door
A microwave door has a window for you to view your food while it cooks and rotates on the turntable. In some microwaves from Whirlpool brand, the appliance will not function if the door has been closed for five minutes or more without being started. If this occurs, a message will display on your control panel. Simply open and close the door to reset. If your microwave is running, opening the door will stop that cooking cycle.
The Production Process of Microwave Oven
The process of manufacturing a microwave oven starts with the cavity and the door. First, the frame is formed using automatic metal-forming presses that make about 12 to 15 parts per minute. The frame is then rinsed in alkaline cleaner to get rid of any dirt or oil and further rinsed with water to get rid of the alkaline solution.
Next, each part is treated with zinc phosphate, which prepares it for electro-deposition. Electro-deposition consists of immersing the parts in a paint tank at 200 volts for 2.5 minutes. The resulting coating is about 1.5 mils thick. The parts are then moved through a paint bake operation where the paint is cured at 300 degrees Fahrenheit (149 degrees Celsius) for 20 minutes.The chassis or frame is mounted in a pallet for the main assembly operation. A pallet is a vise-like device used in conjunction with other tools.
After the door has been painted, a perforated metal plate is attached to its window aperture. The plate reflects microwaves but allows light to enter the cavity (the door will not be attached to the cavity until later, when the chassis is assembled).
The magnetron tube assembly consists of a cathode cylinder, a filament heater, a metal anode, and an antenna. The filament is attached to the cathode, and the cathode is enclosed in the anode cylinder; this cell will provide the electricity that will help to generate the microwaves. Metal cooling fins are welded to the anode cylinder, and a powerful magnet is placed around the anode to provide the magnetic field in which the microwaves will be generated. A metal strap holds the complete assembly together. A thermal protector is mounted directly on the magnetron to prevent damage to the tube from overheating.
An antenna enclosed in a glass tube is mounted on top of the anode, and the air within the tube is pumped out to create a vacuum. The waveguide is connected to the magnetron on top of the protruding antenna, while a blower motor used to cool the metal fins of the magnetron is attached directly to the tube. Finally, a plastic fan is attached to the motor, where it will draw air from outside the oven and direct it towards the vanes. This completes the magnetron subassembly.
The chassis assembly work is performed on a pallet—a work-holding device used in conjunction with other tools—located at the station. First, the main chassis is placed on the pallet, and the cavity is screwed on to the chassis. Next, the door is attached to the cavity and chassis by means of hinges. The magnetron tube is then bolted to the side of the cavity and the main chassis.In a completed microwave oven, the magnetron tube creates the microwaves, and the waveguide directs them to the stirrer fan. In turn, this fan points the waves into the oven cavity where they heat the food inside.
The circuit that produces the voltage required to operate the magnetron tube consists of a large transformer, an oil-based capacitor, and a high voltage rectifier. All of these components are mounted directly on the chassis, close to the magnetron tube.
The stirrer fan used to circulate the microwaves is mounted on top of the cavity. Some manufacturers use a pulley to drive the fan from the magnetron blower motor; others use a separate stirrer motor attached directly to the fan. Once the stirrer fan is attached, a stirrer shield is screwed on top of the fan assembly. The shield prevents dirt and grease from entering the waveguide, where they could produce arcing and damage the magnetron.
The cook switch provides power to the transformer by energizing a relay and a timer. The relay is mounted close to the power transformer, while the timer is mounted on the control board. The defrost switch works like the cook switch, activating a motor and timer to operate the defrost cycle. Also mounted on the control board are a timer bell that rings when the cooking cycle is complete and a light switch that allows viewing of the cavity. A number of interlocking switches are mounted near the top and bottom of the door area. The interlocking switches are sometimes grouped together with a safety switch that monitors the other switches and provides protection if the door accidently opens during oven operation.
A front panel that allows the operator to select the various settings and features available for cooking is attached to the chassis. Behind the front panel, the control circuit board is attached. The board, which controls the various programmed operations in their proper sequence when the switches are pushed on the front panel, is connected to the various components and the front panel by means of plug-in sockets and cables.
The outer case of the microwave is made of metal and is assembled on a roll former. The case is slipped onto the preassembled microwave oven and bolted to the main chassis.
