Embodiment Construction

[0061] There are many variables that affect the brew cycle and brew temperature of a drip coffee maker. This includes the size and brew capacity of the coffee maker, the wattage of the coffee maker, the calibration and reset temperature of the thermostat control used to adjust the brew cycle when the coffee maker is powered on, the length and inside diameter of the check valve body, the piston The shape and weight of the valve, and the distance the piston travels in the check valve body.

[0062] Returning now to the drawings, wherein the same reference numerals represent the same or similar elements, figure 1 A partial cutaway view of a drip coffee maker that may be used with the improved valve of the present invention is shown. The coffee machine 1 includes a body 3 and a glass water container 5 . The carafe is removable and comprises a container 7 with a handle 11 and an optional lid on top. The water container is placed on the top of the water container heater 13 , and ...

Abstract

Drip coffee makers include a one way valve to control a flow of fresh water from a reservoir into a heating conduit via a cold water conduit. Water is heated in the heating conduit, and then proceeds into a hot water conduit, and hot water is thereafter spread over coffee grounds by a showerhead. Heating water causes formation of steam and pressure in the hot water conduit. The one way valve prevents the heated water from moving backwards towards the reservoir, helping force the water onward through the system towards the coffee grounds in the filter basket. Once the heated steam and water move out of the heating conduit the one-way valve is able to open and new fresh water enters. The one-way valves use heavy metal or steel valve stoppers. The stoppers may be spherical, columnar, bullet shaped, or a pair of spheres either loose or fused.

Description

[0001] This application claims priority to US Patent Application No. 61 / 725,554, filed November 13, 2012, which is fully incorporated by reference below. technical field [0002] The present invention generally relates to the field of kitchen appliances, and in particular to a drip coffee machine and a valve for controlling water flow in the coffee machine. Background technique [0003] Drip brewing involves pouring water over roasted and ground coffee beans in a filter. Hot water seeps into the coffee grounds, absorbing its color and flavor, before being drawn by gravity through a filter. The used coffee grounds are retained in the filter while the flavored liquid drips into a collection container below, such as a carafe or jug. Drip brewing is a widely used coffee brewing method, popular both at home and commercially. Manual drip brewing devices also exist, although electric devices that can turn cold water into hot coffee in a single process are more popular. Small sin...
