Major appliance
From Wikipedia, the free encyclopedia
A major appliance is a large machine which accomplishes some routine housekeeping task, which includes purposes such as cooking, food preservation, or cleaning, whether in a household, institutional, commercial or industrial setting. An appliance is differentiated from a plumbing fixture because it uses an energy input for its operation other than water, generally using electricity. An object run by a watermill, however, would be considered an appliance.
Major appliances are differentiated from small appliances because they are large, difficult to move, and generally fixed in place to some extent. They may be roughly divided into refrigeration equipment, stoves, washing equipment, and miscellaneous.
[edit] Types of appliances
Appliances are divided into white goods and brown goods.
- Brown goods are typically household electrical entertainment appliances such as:
- CD and DVD players,
- televisions,
- camcorders
- HiFi and home cinema
- White goods comprise major household electrical appliances including:
- air conditioner.
- breadmaker.
- dishwasher
- clothes dryer.
- freezer and refrigerator.
- furnace, also known as a central heating boiler.
- ironing clothes home appliance : Driron.
- stove, also known as range, cooker, oven, cooking plate, or cooktop
- vacuum cleaner.
- water heater.
- washing machine.
- microwave and advantium.
Some types of brown goods were traditionally finished with or looked like wood or bakelite. This is now rather rare, but the name has stuck, even for goods that are unlikely ever to have been provided in a wooden case (e.g. camcorders). White goods were typically painted or enamelled white, and many of them still are. The addition of new items to these categories shows that the categories still serve a purpose in marketing.
This division is also noticeable in the service area of these kinds of products. Brown goods usually require high technical knowledge and skills (which get more complex with time, such as going from a soldering iron to a hot-air soldering station), while white goods need more practical skills and "brute force" to manipulate the devices and heavy tools required to repair them.
Brown goods are almost always serviceable down to "component-level" (integrated circuits, transistors, etc), whereas in white goods, usually whole modules (motor, thermostat, controller board) are changed and not repaired. There is usually a problem with microwave ovens, which are considered white goods, because these sell alongside refrigerators and dishwashers, but microwave ovens contain complex electronic boards (the clock and controller) which white-good servicemen refuse to repair (as they don't have the training or tools required to do so). Some brands consider microwave ovens white goods, and send whole boards for replacement, and some consider microwaves to be like brown goods, and have them repaired by such technicians.
Whitegoods have become more technically complex from the control side recently with the introduction of the various Energy Labelling rules across the world. This has meant that the appliances have been forced to become more and more efficient leading to more accurate controllers in order to meet the regulations, especially in the EU.
Personal care products (electric shavers and depilators), are considered a separate line, and usually are not serviced, but completely exchanged.
