The subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. The invention, however, may best be understood by reference to the following detailed description of various embodiments and accompanying drawings in which:
Referring to
Mounted in front of the water tank 25 is a concentrate container 39. The concentrate container 39, as shown, preferably includes a flexible bag 41 that collapses as concentrate is consumed. The flexible bag 41 is inexpensive and once emptied is readily disposable. In addition to the flexible bag 41, the concentrate container 39 includes an outlet 43 which is sealed until pierced by a probe 45 which self seals in the outlet 43. The concentrate container 39 is mounted on the probe 45.
As seen in
As seen in broken lines in
The conduit housing 49 also has two ends, namely an inlet end 61 adjacent to the water tank 25 (
In the lower portion 67 of the conduit housing 49 is one or more water conduits 69. The water conduit, as shown in
With referenced again to
With reference now to
The conduit housing 49 at the outlet end 63 has a cylindrical extension 87. A conduit opening 89 extends through the cylindrical extension 87 generally at right angles to the concentrate conduit 51 (
A passageway 99 through the strength valve 93, which is located generally at right angles to the strength valve 93, aligns with the concentrate conduit 51 (
The upper section of the mixing chamber 79 which is also the dispenser housing 81 and the spout 83 are both hollow cylinders and are located generally at right angles to one another. As previously stated, the upper section or dispenser housing 81 is open at both ends and one end is placed over the cylindrical extension 87. On the other end, an external thread 101 is located on which a dispenser assembly 103 is mounted by means of a cap 105. The dispenser assembly 103 includes a stopper 107 which is placed against the outlet end 63 of the conduit housing 49 blocking both the water conduit 69 (
By pressing on the bottom of the handle 115, the actuator rod 109 is pulled back which also pulls back the stopper 107 thereby releasing both the liquid concentrate and the water from the concentrate conduit 51 (

With reference to
In operation, with reference to
The air pump may be operably connected to the electrical power supply to pressurize the air surrounding the flexible bag 41 when the water is at the desired temperature. Alternatively, the apparatus may be configured so that upon initially activating the handle 115, the air pump is activated to pressurize the air surrounding the flexible bag.
As shown in
With the switch 323 turned on, a light 325 is turned on and illuminates a red actuator 324 to alert the user that power is being supplied to the apparatus. In the “on” position and if sufficient water is in the water tank, switch 390 controlled by the float valve 373 allows electrical power to be supplied to an electric circuit 340 comprising a thermo button or temperature sensor 339 and a heater 330 such as a coil heater. The temperature sensor 339 may be attached directly to the water tank (
When the desired temperature of the water is achieved as detected by a second thermal button or temperature sensor 351, a light 350 such as a green light is illuminated to alert a user that the water is at the desired temperature for making the beverage. If the water temperature drops, the light 350 would go out and remain out until the water returns to the desired temperature. As described earlier, the apparatus may include a heating element, however, a cooling element for producing cold beverages may be suitably employed.
It is appreciated that the apparatus may be manually filled with water avoiding the need for providing a conduit attached to the apparatus, and attached to the water supply in, for example, a home or business. In addition, an apparatus may include two dispensers, for example, one configured for providing regular coffee or tea, and the other for providing decaffeinated coffee or tea. Further, by closing the strength valve no liquid concentrate will be delivered from the dispenser so as to provide only hot water where a heating element is employed or cold water where a cooling element is employed.
Referring now to
A supply line 431 (such as from a water supply in a home or building) provides water to apparatus 400. The supply line 431 connects to a tube 432 which in turn connects to a water pressure regulator 434 which reduces the pressure from the supply line (typically about 60 psi) to about 5 psi. The reduced pressure water supply is transferred via a tube 436 to a conduit housing 449 as described in greater detail below.
A tube 445 connects at one end to the flexible bag 441 and at the other end to conduit housing 449 for transferring liquid concentrate from flexible bag 441 to conduit housing 449. An air pump 410 provides a low positive air pressure, of about 2 pounds per square inch (psi) to about 10 pounds per square inch (psi), to the bottom portion of the enclosure 411 to provide a constant positive pressure around the flexible bag 441.
As best shown in
One end of the concentrate conduit 451 is connected to a hollow projection 447 (
The conduit housing 449 is connected to a mixing chamber 479 (
The rate of concentrate to be delivered to the mixing chamber is controlled by a strength valve 493 which selectively extends into concentrate conduit 451. The strength valve 493 may be a cylindrical rod or flat bar having a lower end which is disposed in concentrate conduit 451 and an upper end which is disposed adjacent a movable ramp 495. A coil spring 491 biases the upper end of strength valve against ramp 495. By moving a strength lever 497 attached to ramp 495 in the direction of double-headed arrow A (

In operation, with reference to
The advantages of the various apparatus described above are many. In one embodiment, by use of gravity feed for both the water and the concentrate, the need for manual and/or powered fluid pumps are eliminated. In another embodiment, the use of an air pump allows providing a constant liquid concentrate flow. The cost of the various apparatus is brought down to a reasonable level for home and office usage and the compact size of the apparatus is also suitable for home and office use. The mixing chamber provides excellent blending and mixing resulting in a very desirable drink. The various apparatus also allows a user to readily select the strength of the beverage. When used with liquid coffee or tea concentrate, an exceptional coffee or tea drink is produced. When brewing coffee or tea from liquid concentrate there are no filters or used coffee grounds or tea leaves to clean up. A user can brew a fresh cup of coffee or tea one cup at a time on demand.
While various embodiments of the present invention have been illustrated and described, it will be appreciated by those skilled in the art that many further changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
