BRIEF DESCRIPTION OF THE DRAWINGS

The fresh water reservoir 12 has transparent sidewalls 30. The transparent sidewalls 30 allow users to easily and immediately determine whether and how much fresh water is in the coffee maker 10. Of course, nontransparent walls may be used, or a vertical window slot could be used. A water level indicator may also facilitate the ability of a user to accurately gauge the water volume.
The fresh water reservoir 12 rests on the stand 11. The fresh water reservoir 12 wraps partially around the brewed beverage tank 13. The brewed beverage tank 13 also rests on the stand 11. The brewed beverage tank 13 has a transparent window 25 which allows a user to observe very easily and quickly how much brewed beverage is contained within the tank 13. Finally, a lid 14 is rotatably connected to back wall of the reservoir 12. The lid 14 is adapted to cover both the fresh water reservoir 12 and the brewed beverage tank 13.
The platform 50 includes a warmer plate 51 which is adapted to engage the bottom of the brewed beverage tank to keep a brewed beverage inside the tank warm. The platform 50 is molded in part into a recess that is adapted to receive in a mating fashion the molded male portion 110 (see
The brewed beverage tank 13 is made up of the filter basket 40 that has an aperture 41 at the bottom of the filter basket to allow the infused water to drip into the reservoir portion 45 of the brewed beverage tank 13. An outlet port 70 is the aperture through which the brewed beverage may be allowed to exit the brewed beverage tank 13. The filter basket 40 is conventional in structure and dimension in order to be easily usable. As is also evident from

Push button 21 is connected to one end of lever 80. Lever 80 has a pivot point 81 that is a hinge mounted behind the front face 82 of the stand 11. The opposite end 83 of the lever 80 protrudes through aperture 53 (see

The present development includes a valve that closes the flow from a reservoir wherein the lower end of the valve has a reduced area for coffee or other brewed beverage to drip from. Specifically, the plug portion of the valve arm lever is made in the shape of a geometry that enhances the efficient flow of liquid across the plug body.
In terms of physics, the demonstrated plug construction reduces drippage from the reservoir as a result of the inverted conical shape of the cone 155 on the bottom of the stem 153 of the plug 151. This conical shape creates less surface area on which the coffee may stick and then drip from once the valve is closed. Still further, this conical shape increases the laminar flow of the liquid out of the reservoir. The performance of the present construction is enhanced by a relatively stiff spring 170 holding the push button 170 in the closed, biased position. In this way, the first lever 172 does not block or hinder the operation of the bias spring 185 in the second lever 150.
The brewed beverage tank 325 is shown and has the appearance of a traditional coffee carafe. The brewed beverage tank 325 includes a handle 330 and a solid top 329. The top 329 essentially covers the filter basket 335 when the filter basket is mounted within the brewed beverage tank 325 except that there is an opening (not shown) proximate the spout 326 of the brewed beverage tank to enable the flow of hot water into the filter basket during brewing. The brewed beverage tank 325 includes a transparent window 327 that allows the user to observe the level of brewed beverage contained within the brewed beverage tank 325. The reservoir portion 324 of the brewed beverage tank 325 is that portion of the brewed beverage tank below the filter basket 335.
The bottom of the brewed beverage tank 325 includes two valves 340 and 342. The first valve 340 is a one-way valve that dispenses fresh water from the brewed beverage tank 325 into the fresh water reservoir 345. In operation, a user fills the brewed beverage tank with a desired amount of fresh water at a sink or other water source. The brewed beverage tank is then placed onto the stand 310. When in place on the stand 310, the valve 340 opens to allow fresh water to pass from the brewed beverage tank 325 into the fresh water reservoir 345. The valve 340 may be manually operated by a user to open and allow the fresh water to pass into the fresh water reservoir 345. The valve 340 must be closed during the brewing process so that the brewed beverage tank 325 may retain the brewed beverage within the reservoir portion 324 of the brewed beverage tank. An alternative to manual operation to open and close the valve 340 is a temperature sensitive or time limited valve. Other types of valves to allow only fresh water to pass through may alternatively be used.
The second valve 342 is mounted in an outlet port 343. The valve 342 controls the flow of brewed beverage out of the brewed beverage tank 325. The valve 342 is operatively linked to the push-button actuator 316 positioned in the recess 312 of the stand 310. In use, a user places a cup or other beverage vessel in the recess 312 and presses against the actuator 316. This causes the valve 342 to open and allows brewed beverage to flow out the outlet port 343 and into a beverage vessel.
An alternative way to use of the brewed beverage tank 325 is for the user to remove it as customary with a traditional carafe. The brewed beverage tank 325 is removable from the stand substantially in the direction of the front of the stand. The brewed beverage tank 325 may be used to pour the brewed beverage out of the open top of the brewed beverage tank 325. On the front of the brewed beverage tank 325 is a spout 326 that allows the user to dispense the brewed liquid in the traditional carafe fashion. The result is that the user has the option of the 1-handed, single cup at a time dispenser using the valve 342 and the push-button actuator 316. Alternatively, a user can use the brewed beverage tank 325 as a carafe and pour the brewed liquid out the spout 326 in a traditional fashion.
As shown, the brewed beverage tank 325 is removable in the direction of the front side 305 of the hot beverage maker 300. This front side directional removability makes a brewed tank/carafe very accessible by a user. The illustrated embodiment also shows at least some accessibility and removability to the sides as well. The front side directional removability is distinguished from other hypothetical constructions that require a substantially vertical or back side accessibility only. Given a crowded countertop and overhead shelves, for instance, front side accessibility can be an important feature. Finally, front side removability does not mean a literal, horizontal motion only. It means that the horizontal, front side dimension of the removal function is allowed to be greater than any vertical or side direction of removal.
While the invention has been described with reference to specific embodiments thereof, it will be understood that numerous variations, modifications and additional embodiments are possible, and all such variations, modifications, and embodiments are to be regarded as being within the spirit and scope of the invention.
