Beverage brewing system

Abstract

A brewer system is adapted to brew a beverage utilizing a cartridge packed with beverage grind such as coffee, tea, milk, and the like. The brewer system may include a pump adapted to draw the fluid from either a reservoir or a heater tank utilizing a vacuum pump. The pump may pass the fluid to a brewing chamber adapted to receive the cartridge and inject the fluid into the cartridge to brew a beverage. The pump may draw the fluid from a tube having a first end and a second end, the first end may be coupled to the pump, and the second end of the tube adapted may draw the fluid. A portion of the tube may be elevated above the maximum fill line of the fluid within the reservoir or the heater tank. An air switch may be coupled to the portion of the tube such that atmospheric air may enter the portion of the tube through the switch after a predetermined amount of fluid has been pumped through the tube to purge the cartridge of beverage.

Description

RELATED APPLICATION[0001]This application claims priority to four U.S. provisional application numbers: (1) 61 / 690,275, filed Jun. 22, 2012; (2) 61 / 849,236, filed Jan. 22, 2013; (3) 61 / 850,862, filed Feb. 25, 2013; and (4) 61 / 852,470 filed Mar. 15, 2013, which are all hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention is directed a beverage brewer system adapted to provide hot water through a cartridge adapted to make a predetermined beverage; and in particular, the beverage brewing system adapted to make coffee using the cartridge having a premeasured coffee grind therein.[0004]2. Background[0005]Brewing coffee through a single-serve cartridge has become popular for its convenience and a variety of coffee flavors that are offered. Single-serve cartridges are packed with pre-measured coffee grind that can be inserted into a brewer to inject heated water into the cartridge to brew a cup of coffee. In general, a single-serve...

AI Technical Summary

Benefits of technology

The patent describes a brewer system that includes a heater tank with an opening that allows air to pass through. The heated fluid is then pulled through a tube using a vacuum pump. A temperature sensor measures the temperature of the fluid in the heater tank, and the system processor adjusts the temperature and the speed of the pump to control the flow rate of the fluid. This way, the temperature of the fluid is independent of the flow rate, resulting in a beverage with the best taste for the consumer.

Problems solved by technology

This may allow the processor to authenticate the indication mark on the cartridge, and if the processor determines that the indication mark is not authentic, then the processor may not operate the brewing system.
