Home Appliances - parts and functions

This article is going to deal with a few of the electrical appliances that we use in our day to day life. It is very necessary to know the basic information of such devices, working of those devices and the amount of power they consume.

We are aware that most of the home appliances run with the help of electricity. Some appliances may convert this electricity into some other form of energy. However, every home appliance makes use of an 'electric motor' according to its usage and need.

A basic electric motor contains wire winding, rotating shaft and a magnet that helps to convert the available electric current into rotational current that can do mechanical work. This is the basic electric motor and it is altered or modulated in different home appliances according to their needs.

Depending on the function of the home appliance, different things can be attached to the motor shaft. For example, in a food processor or blender, along with the basic design of a motor shaft, a set of blades are included to make the chopping and blending simpler. The similar design appliance is an Electric mixer which has same functions and parts except that they have less RPM (Rotation per Minute). Thus, more or less, all appliances have the same design with few alterations according to its function.

Now let's see few such appliances and how they work:


This is one such appliance that can be found in any home. Consumers feel that refrigerator is the one of the important appliance that everyone should have to preserve foods, fruits, beverages, etc. Thus, let's see the important parts of the Refrigerator.


It is the "Refrigerant" that carries out the cooling effect in the evaporator (Freezer) and all the internal parts of the Refrigerator. It absorbs heat from the substance, cools it and then throws the cooling effect via condenser.


A refrigerator compressor is the centre of the refrigeration cycle. It controls the function of Refrigerant and adds pressure to it by heating up. This is the most power consuming part of a refrigerator and it is present at the back bottom of the fridge.


As the refrigerant passes the condenser, a fan blows air into copper tubes that condenser has. This cools down the refrigerant and excess heat leaves the refrigerator. This heat is again transformed into liquid and then travels back the evaporator to repeat this cooling cycle.

Facts about Fridge

1. A refrigerator typically accounts for around 10% of your home's electricity bill.
2. 1/3 of the refrigerator chillness gets out every time you open your fridge. Thus, a closed door saves you energy and power.
3. You can make use of energy efficient refrigerators that make use of less power than the conventional models of refrigerator.
4. Older refrigerators must be disposed properly because of the environmental damage materials they contain.

Air conditioner

Air conditioners are refrigerators work the same way. Refrigerator cools the small given space inside the appliance whereas the air conditioner cools down the whole area or room. Air conditioners make use of chemicals that easily converts from a gas to a liquid form and vice versa. This chemical is used transfer heat from the home inside to the outside air. This too has the same parts as that of refrigerator such as compressor, condenser and evaporator.

The function of a compressor is just like a bicycle pump which sucks in air and compresses in the tyre. Similarly a function of a condenser is turning water back to its liquid form. Evaporator removes the heat from the area that is cooled.

2. Try to change your filters at least once every year.
3. Do not install the AC where radiated noise may come from the neighbor's window.

This consists of parts like: 1. An intake port: This may include variety of cleaning accessories.
2. An exhaust port
3. An electric motor
4. A fan
5. A porous bag
6. A housing that contains all other components.
