DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the following description of the present invention, reference is made to an apparatus for brewing coffee. However, it should be understood that the apparatus is also adaptable to brewing alternative beverages such as tea, hot chocolate and the like by utilizing the appropriate brewing ingredients such as tea leaves, cocoa or the like. User's fingers are number “81.”
Referring to the drawings, and in particular to FIGS. 1 and 2, there is shown an apparatus 10 for brewing coffee, in accordance with the present invention. The apparatus 10 includes outer shell 12 having handle 9 and a suitable heat insulating material 11 such as plastic foam materials, including polyurethane, polystyrene or the like. Shell 12 includes inner coffee storage compartment 14 dimensioned and configured to receive the brewed coffee which drips downwardly from the brewing chamber 13 positioned directly there above. Cup or mug 15 is attached by interference lip means or alternatively, by threads, to upper housing section 30.
Referring again to FIG. 2, heating element 16 is located below the coffee storage compartment 14 and is appropriately supplied with electrical power via electrical wire 18, which is capable of being powered by a conventional 110 volt duplex wall outlet via plug 20. Alternatively, wire 18 can be powered through a motor vehicle accessory socket or cigarette lighter socket via alternative plug 22 shown in FIG. 2. In yet another embodiment as shown in FIG. 1, wire 18 can be powered through a motor vehicle accessory socket in an automobile, SUV, RV, Mini-van, boat or the like, or through a cigarette lighter socket utilizing a motor vehicle power inverter 24 shown in FIG. 1. Such power inverters are generally available from motor vehicle retail parts suppliers and transform direct current (DC) to standard type household alternating current (AC) and are available for various power levels. Examples of such power inverters are inverters marketed by Xantrex Technology Inc, of Buraby, Canada, under the trade names Prosine Power Wave Inverters, X Power Inverters and the like. Other such inverters are available from Vector Manufacturing Inc. Any suitable power inverter may be used with the present invention. Furthermore, preferably power wire 18 may be made to be disconnected from the coffee maker by optional removable socket 19 shown in dash lines, in FIG. 1.
Referring to FIGS. 1 and 2, shell 12 includes inner water storage jacket 26 which has sufficient volume to receive cold water suitable for user in brewing the beverage. The cold water is introduced through upper opening 28 after removal of upper section 30 which contains brew valve 32, which will be described in greater detail herein below.
Water storage jacket 26 includes heated water conduit 34 which receives heated water through “one-way” spring biased pressure valves 62, 64 which are made to open when the water in jacket 26 is heated sufficiently to a boiling temperature. When heated, the water enters conduit 34, through spring biased pressure valves 62, 64 and is directed up to brew valve 32 which will now be described.
Referring to FIG. 2, upper housing section 30 is attached to lower housing section 36 of outer shell 12 by high pitch threads 38, and sealed by elastomeric seal 40 so that the system is completely sealed and fluid-tight when brewing the beverage. Brew valve 32 includes rotatable knob 42 attached by connecting tube 44 to spherical chamber 46. The upper section 45 of spherical chamber 46 as shown in FIG. 2 may be made of plastic, metal or the like. The lower section 47 of spherical chamber 46 shown in FIG. 2 is a filter screen 48 which may be of coffee filter porosity to filter the brewed coffee. Alternatively, the filter screen 48 may be provided with larger screen openings and a separate paper coffee filter may be placed thereon and the coffee grounds 50 (i.e. ground coffee) placed on the filter paper as in conventional coffee makers. Still alternatively, the coffee grounds may be introduced into the brew valve 32 by placement of the well-known coffee pods which comprise coffee grounds 50 contained with a pouch made of filter paper.
Referring again to FIG. 2, a screen 52 having larger openings than filter screen 48 is attached and positioned as shown above the coffee grounds 50 for evenly distributing the heated water from conduit 34 during brewing, which may or may not be approaching a gaseous (or steam) phase.
The heated water rises in conduit 34 and thereafter enters brew valve 32 through connecting tube 44, then passes over screen 52, so as to be evenly distributed in the form of droplets onto the coffee grounds 50 to provide a fully brewed beverage. After passage through the coffee grounds 50 and filter screen 48 the final product in the form of brewed coffee is collected and stored in the coffee storage compartment 14.
Referring again to FIGS. 2 and 6, it can be seen that after insertion of the plug 20 into the wall outlet, the heating cycle of the water in jacket 26 can be initiated by turning brew valve knob 42 to clockwise to the position shown in FIG. 6 so as to depress rod 54 against spring 56 to in-turn, depress switch 55 to activate heating element 16. When heating element 16 is activated, the “ON” light 58 becomes illuminated, as shown in FIGS. 1 and 2. When rod 54 is released by rotating knob 42 to the position shown in FIGS. 8 and 9, switch 55 is inactivated and the “ON” light 58 is turned off. Simultaneously, the “OFF” light 60 is turned on. Lights 58 and 60 may be color coded, such as red and green.
Referring once again to FIG. 2, in conjunction with FIGS. 6, 7, 9 11, 12 and 15, the operation of the brew valve 32 will now be described. In FIGS. 2 and 6, brew valve 32 is shown in the coffee brewing position. Access to the brew chamber 13 is provided by rotating and unscrewing cap 62 as shown in FIG. 15. Once brew valve 32 is rotated 180 degrees by turning brew valve knob 42 as shown in FIGS. 8 and 9, the removable filter screen 48 may be removed for cleaning and placement of coffee grounds 50 (or coffee pod) into the chamber 13 and onto screen 52 as shown in FIG. 15. It can be seen that when brew valve 32 is in the position shown in FIGS. 8 and 15, vents 31, 33 and 35 are not aligned so as to seal the system.
After placement of the coffee grounds 50 onto screen 52 as shown in FIG. 8, filter screen 48 is then placed into position and retained by end clips 51, 53. Brew valve 32 is then rotated 180 degrees clockwise from the position shown in FIGS. 8 and 9 to the position shown in FIGS. 2 and 6. Extension arm 43 of brew valve knob 42 engages and depresses rod 54 which in turn engages switch 55 to activate heating element 16 to heat the water in water storage jacket 26. At the same time vents 31, 33 and 35 become aligned to permit venting of the water storage jacket 26 and the coffee storage compartment 14 for brewing coffee. Once the water is heated to the boiling point (or possibly approaching a steam phase), pressure develops to cause the heated fluid to depress spring biased one-way flow valves 62, 64, thereby permitting the heated fluid to transfer from the water storage jacket 26 and to rise upwardly into conduit 34 and into the brew chamber 13 of brew valve 32, while air is permitted to enter the water storage jacket 26 via the vents 33, and to exit the coffee storage compartment 14 via the vents 31. Ultimately, all of the escaping air exits the system through whistle 69 and then through aperture 66. When the brewing cycle has been completed, the vigorous flow of air and/or steam through aperture 66 will cause whistle 69 to be activated to provide an audible signal of completion of the brewing cycle.
After completion of the brewing cycle as described, access to spout 68 is obtained by lifting spout extension arm 72 of rotatable “ball-type” pour valve 70 to the position shown in FIG. 14 to permit pouring the brewed coffee into a mug or container 15 as shown.
Higher pressure safety valve 63 permits release of steam or water in the event fluid flow becomes blocked due to clogging of components in the system.
Referring to FIGS. 2, 6, 11 and 12 there is illustrated the procedure for removal of upper housing section 30 from lower housing section 36. Knob 42 of brew valve 32 is first rotated from the “ON” (or 6 o'clock) position shown in FIG. 6, 270 degrees to the “NEUTRAL” (9 o'clock) position shown in FIG. 12. In this position the brew valve 42 is oriented as seen in FIG. 11, with the filter screen 48 in the 9 o'clock position, as would be viewed with respect to FIG. 12. Thereafter, the upper housing section 30 may be rotated counterclockwise as viewed from above to release high pitch threads 38 thereby permitting removal of the upper housing section 30. Rotation of upper housing section past rod 54 is made possible by the configuration shown in FIG. 12 whereby arcuate camming heal 30a rises above rod 54 due to the fact that threads 38 shown in FIG. 1 are of relatively high pitch. Therefore while camming heal 30a may depress rod 54 slightly, rod 54 is not depressed sufficient to activate switch 55 when the upper housing section 30 is removed. During this movement, vents 31, 33 are misaligned as shown in FIGS. 11 and 13 so as to prevent liquid or air from escaping from the system.
Once upper housing section 30 has been removed, the upper opening 28 of water storage jacket 26 is exposed for introduction of sufficient cold water for initiating the brew. While one cup of water is contemplated, the apparatus can be made larger to receive sufficient water to brew more than one cup of coffee.
Referring to FIGS. 17 and 18 there is illustrated an alternative embodiment 74 of a pour spout which includes release bar 76 biased toward the closed position by spring 78 whereby movable plate 80 blocks the fluid flow through spout 82 as shown. Upon depressing bar 76 downwardly against spring 78, by finger 81 shown in phantom in FIG. 18, plate 80 moves downwardly to align aperture 84 with spout 82 to permit pouring the beverage out of the coffee storage compartment 14. FIG. 17 shows the location for positioning of a user's finger 81, as is shown in phantom in FIG. 18.
FIG. 18 also shows an alternative structure to remove upper housing section 30 by pivoting about pivot pin 86, using an appropriate snap locking device (not shown) on the opposite side to lock the upper housing section 30 to the lower housing section 12.
