FIELD OF THE INVENTION

The present invention relates generally to an apparatus for a refrigerator. More particularly, the present invention is a refrigerator which provides personal locking compartments for use by multiple individuals.

BACKGROUND OF THE INVENTION

A refrigerator, colloquially known as a fridge, is a common household appliance that consists of a thermally insulated compartment and a mechanical, electronic, or chemical heat pump that transfers heat from the inside of the fridge to its external environment so that the inside of the fridge is cooled to a desired temperature below the ambient temperature of the room. A fridge is useful for storing food, since lower temperatures in a confined volume lowers the reproduction rate of bacteria, which has the result of reducing the rate of food spoilage. A fridge typically maintains a temperature a few degrees above the freezing point of water. Many refrigerators also include a freezer compartment separate from the refrigerator compartment that maintains a temperature below the freezing point of water.
Refrigerators exist in many places of employment for the use of the employees who bring their meals to work. The refrigerators that are used in these multi-person environments are standard refrigerators that generally include multiple shelves, a few drawers, a door with shelving and a freezer with one or more shelves. This standard refrigerator design is widely used throughout the world in, to name a few, homes, schools and places of employment.
The design and function of the standard refrigerator has been improved in various ways over the years; however, there is not a refrigerator that specifically exists for exclusive use by multiple individuals in a multi-person office environment. Because the conventional refrigerator storage space is communal, items may be mistakenly or intentionally taken or misplaced which can cause distrust or unrest among those sharing the storage space. In addition, there is a considerable amount of food waste that occurs due to individuals forgetting that they have place food items in the fridge.
It is therefore an object of the present invention to provide a refrigerator that eliminates the possibility of conflict or animosity in an office caused by one person misplacing or disturbing another person's food items by providing compartmentalized and personalized storage drawers that secure individuals' items against misuse, and to reduce instances of wasted food by having drawers that notify a person when they have forgot they have food in a drawer.
