Through the years there have been many technological advances that have improved our daily lives. The advancement that has proved to have the most effect is the creation of appliances available to the average consumer. These appliances, such as washing machines, ovens, vacuums, toasters, and refrigerators, have made the lives of their owners easier for decades. As time goes on these appliances become better, cheaper, and more energy efficient. This makes it easier to own an appliance and now it is virtually impossible to find a home that doesn’t contain at least one large or small appliance.
There are appliances to meet virtually any daily need. There are appliances that clean your clothes, wash your dishes, cook your food, cool your food, clean your house, and virtually anything else you can think of. One of the most popular appliances is the refrigerator. The refrigerator is a device that keeps whatever food placed inside of it at a lower temperature than the temperature of the room it is in. The refrigerator is designed so that, if placed in a room of average room temperature, it will keep the food a few degrees above the freezing point of water. Most refrigerators come with an attached freezer unit. This freezer unit is used to cool foods placed in it to below the freezing point of water, hence the term freezer. Some refrigerators have areas, besides the freezer section, where the food is kept at different temperatures. This allows you to store virtually any type of food in your refrigerator regardless of the temperature it needs to be kept at. A common new feature of a refrigerator is to have a built in ice maker and water filter. That way you don’t have to use ice trays to make ice and you can get cold and filtered water instantly from your refrigerator.
Another very popular appliance is the stove. The stove is a device that is used for heating food placed in some form of metal container. The stove is usually installed in a section of the counter in the kitchen. Modern stoves produce heat by either burning natural gas or running electrical current through a resistant conductor. There are pros and cons to each type. Natural gas burning stoves allow greater and more immediate control of the heat being produced, due to the ability to control the size of the flame, but they tend to heat foods unevenly. Electric stoves heat food more evenly but have less immediate and precise heat control, due to the fact that the conductor has to have time to heat and cool.
The large demand for these appliances has caused a large demand for people to provide maintenance and fix them when they break. This demand has caused businesses that specialize in the maintenance and repair of home appliances to flourish. Many of these businesses have expanded to also include the purchasing and installation of home appliances. Some businesses even refurbish used appliances and appliances that have been damaged during their initial construction. They then sell them at a lower price to consumers.
