- Introduction
This technical description will describe the function of a Mr. Coffee® Advanced Brew Coffee Maker. The main function this paper will be focusing on is the machine’s brewing ability. This machine, or device, makes coffee from extracting the caffeine from ground coffee beans. Its main purpose is to minimize the normal amount of labor it takes to make coffee.
This specific brand of coffee maker is a drip brew and programmable model (Mr. Coffee Manual). The programmable features on the control panel lets you pre-set the time you want your coffee to be made. This feature removes any unnecessary delays and helps if one day you’re running late for work and don’t have time to wait for the coffee to brew. Also included on the control panel is a clock, which is always useful.
For brewing, the coffee maker has four main parts. The control panel, water heating and circulating system, shower head, and decanter. The first part, the control panel, is for the user’s overall operation of the device. The water heating and circulating system circulates and heats up any water that passes through the shower head, and the extract, or coffee, is held in the decanter (Mr. Coffee Manual).
III. Parts Labeled
III.1 Control Panel Labeled
The control panel (Figure 2.0) is the silver square portion of the machine. This is where the programmable features are, and where a person would operate the machine to begin the brewing process. The control panel includes the following buttons/features:

III.2 Water Circulating and Heating System
At the bottom of the coffee maker is a heating element and some tubes that work together to make the coffee (Air & Water). All this system needs to work is water in its reservoir (#5 Figure1.0), which can hold up to 12 cups (Mr. Coffee Manual). This system will heat up water in the reservoir to boil, and then the water will travel up along the column and into the drip area, where it drips evenly on the coffee grounds in your coffee filter (Air & Water). As hot water drips on the grounds, your coffee is made and extracted into the decanter.
III.3 Shower Head
The shower head (Figure 3.0) is where the coffee filter and grounds are placed. Some models of this machine come with a permanent filter made of plastic (Mr. Coffee Manual). For models that don’t come with this filter, there is space in the shower head where you’re supposed to place your own coffee filter with the grounds in it, as shown in Figure 3.0. The use of a filter is to separate your extracted coffee from the grounds.

III.4 Decanter
The decanter is the round cup at the front of the machine. Made of transparent plastic material, the decanter is what holds your coffee while the machine brews it. The warming plate that the decanter sits on (Figure 1.0) is also connected to the machine’s heating element which keeps the brewed coffee warm (Mr. Coffee Manual).
- Conclusion
The Mr. Coffee® Advanced Brew Coffee Maker is a very useful device. It saves time and human labor by getting the job done while you may do something else, for example, like getting dressed or reading the morning paper. This is also why it’s an important device in society today. Realistically, everyone works, and a lot of people who work early in the morning drink coffee before work. Having a device like this handy makes the mornings easier to take on. In addition, since the coffee maker can make many cups of coffee at a time, it is very useful in an office setting for employees, serving many people at once.
In the future, I can see coffee makers changing. I can see them becoming more efficient by cutting out the part of the process where the user has to replace filters and add coffee grounds. Maybe future machines will be able to store several coffee filters at a time, and also store large amounts of coffee grounds in them. This way, you can set your machine to have your coffee ready at a specific time almost every day without even having to touching it.
