The refrigerator is one of the most needed appliances in the home today. We need to be able to buy our food and keep it safe to eat without fear of bacteria. The refrigerator keeps your food items safe by keeping them cold. Many items would spoil causing food poisoning for us all if it was not for the refrigerator. The first version of a cold box or refrigerator was an ice box. The local ice plant delivered a block of ice that was placed inside the refrigerator unit in order to keep our foods cold enough so that they would not spoil. Eventually with the invention of electricity the modern refrigerator was born. It became so much simpler to just plug the unit into the electricity and not worry about melting ice.

The electrical units were very good and provided a much safer means of keeping our foods from spoiling. The units were a problem in the fact that they over froze the freezer unit often causing the housewife to constantly defrost this part of the unit. This took much work and time away from other household chores. Eventually, the manufacturers invented a frost free freezer that no one has to defrost. This made keeping our foods even safer without any taste of the frozen frost build up in the freezer unit. We now are able to keep meats, ice creams, and frozen foods at one temperature level for their safety while we can keep other items like our milks, fruits and vegetables at a different temperature.
