Coffee maker

The Wigomat was the world's first electric appliance to make coffee using the infusion method.
The device consists of a glass reservoir for up to one litre of water. Below the reservoir is a heating element that heats the water, causing it to rise through the riser tube to the coffee filter. This filter basket is filled with ground coffee inside a round paper filter. The coffee then drips into the glass coffee pot, which is on a hot plate.
