Patent Issued for Dual Heater Coffee Maker


A patent by the inventors Rizzuto, Leandro P. ( Sheridan, WY); Laskowski, Joseph J. ( Derby, CT), filed on August 6, 2012, was published online on September 26, 2017, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 9770128 is assigned to CONAIR CORPORATION ( Stamford, CT).

The following quote was obtained by the news editors from the background information supplied by the inventors: “Various coffee makers exist for brewing coffee. For example, known drip-style coffee makers heat water from a water reservoir and transport the heated water to a shower head where it is distributed over ground coffee in a brewing chamber to produce brewed coffee. The brewed coffee exits the brewing chamber and is collected in a brewed coffee container retained on the base of the coffee maker.

“While existing coffee makers are generally suitable for what is regarded as ordinary performance, there is room for improvement in terms of the quality of the coffee produced. In particular, with known drip-style coffee makers, after the water is heated, and before it enters the shower head, the temperature of the heated water decreases due to heat losses to the surrounding area. As a result, the brewed coffee is often not hot enough to suit many users’ preferences.”

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors’ summary information for this patent: “It is an object of the present invention to provide a coffee maker.

“It is an object of the present invention to provide a coffee maker that produces coffee at a sufficiently high temperature.

“It is an object of the present invention to provide a coffee maker capable of producing coffee at a variety of temperatures according to a user’s preference.

“These and other objects are achieved by the present invention.

“The coffee maker of the present invention includes a housing, a water reservoir disposed in the housing and a shower head in fluid communication with the water reservoir. The coffee maker also include a first heating element for heating water from the water reservoir and being controllable between and ON state and an OFF state, and a second heating element located downstream from the first heating element and being controllable between an ON state and an OFF state. The first and second heating elements are operable in at least a first mode and a second mode, the second mode being different from the first mode.”
