Abstract

A device and mechanism for recommending a water filter in a beverage dispenser is described. A sensor senses qualities of unfiltered water. Another sensor senses qualities of a flavorant container, such as the flavorant contained within the container. Based on the quality of the unfiltered water and the particular flavored beverage desired, the device will recommend a water filter to optimize the flavor of the beverage.

First claim

What is claimed is:

1. A beverage dispensing apparatus comprising:
a water inlet adapted for connection to a source of unfiltered water;
a water pathway from the water inlet to a dispensing outlet at or near a beverage dispensing area;
a replaceable water filter in operable connection to the water pathway between the inlet and the dispensing outlet, the water filter having an inlet that receives unfiltered water and an outlet that directs filtered water into the water pathway upstream from the dispensing outlet, the water filter configured according to a first type of plural types of filtering characteristics related to removing one or more impurities from the unfiltered water to produce the filtered water for a beverage dispensed from the beverage dispensing apparatus, the beverage comprising the filtered water and a flavorant;
a water quality sensor in the water pathway upstream from the water filter that detects a quality of the unfiltered water;
a processor including programming with logic and data adapted to make a determination of a recommended type of water filter to optimize a flavor of the beverage made using the filtered water and the flavorant, wherein the determination is made using at least one input to the processor comprising a signal including data related to a quality sensed by the water quality sensor and a flavorant type of the flavorant, wherein the recommended type of water filter may be different than the first type by its filtering characteristics:
a water filter indicator display device that visually indicates an indication of the recommended type of water filter based on a signal from an output of the processor; and
a flavorant dispenser for dispensing the flavorant for mixing with the filtered water to produce the beverage, the flavorant dispenser comprising a flavorant container containing the flavorant, an outlet from which flavorant from the flavorant container is dispensed, and a flavorant dispensing actuator controlled by a signal from an output of the processor;
so that various flavorant or flavorant an be associated with a desired water quality for optimizing or enhancing dispensed beverages.

2. The beverage dispensing apparatus of claim 1 , further comprising a flavorant container sensor that detects a quality of the flavorant container, the recommended type of water filter being based in part on the detected quality of the flavorant container.

3. The beverage dispensing apparatus of claim 2 , wherein the detected quality of the flavorant container is a marking on the container that indicates a flavor of the flavorant.

4. The beverage dispensing apparatus of claim 3 , wherein the flavorant container sensor is a bar code reader.

5. The beverage dispensing apparatus of claim 2 , wherein the flavorant container sensor senses a shape of a portion of the flavorant container.

6. The beverage dispensing apparatus of claim 1 wherein the processor is in operable communication with the water quality sensor and the display, the processor is adapted to receive a signal from the water quality sensor indicating the detected quality, the processor is programmed to determine the recommended type of water filter based on the detected quality, and the processor is adapted to send a signal to the display device corresponding to the recommended type of water filter, the display device comprising a video screen, LCD screen, or LED array.

7. The beverage dispensing apparatus of claim 1 , wherein the detected quality of the unfiltered water is water hardness.

8. The beverage dispensing apparatus of claim 1 , wherein the detected quality of the unfiltered water is a level of an impurity.

9. An appliance including a flavored beverage dispenser, the appliance comprising:
an appliance body including a beverage dispensing area;
a supply of unfiltered water within the appliance body;
a water quality sensor in operable association with the unfiltered water, the water quality sensor adapted to sense a quality of the unfiltered water;
a water filter that includes an inlet in communication with the unfiltered water and an o in communication with the beverage dispensing area;
a flavorant dispenser including a flavorant container and a dispensing actuator, the flavorant dispenser having an outlet in communication with the beverage dispensing area;
a flavorant container sensor in operable association with the flavorant dispenser that senses a quality of the flavorant container;
a water filter indicator display; and
a microprocessor adapted to receive a signal from the water quality sensor indicating the sensed quality of the unfiltered water, the microprocessor also being adapted to receive a signal from the flavorant container sensor indicating the sensed quality of the flavorant container, the microprocessor being programmed to determine a recommended type of water filter from a set of types based on the sensed quality of the unfiltered water and the sensed quality of the flavorant container to optimize a flavor of a beverage made using water filtered by the water filter and flavorant dispensed from the flavorant container, the microprocessor adapted to send a signal to the water filter indicator display to cause the indicator display to display an indication of the recommended type of water filter.

10. The beverage dispenser of claim 9 , wherein the detected quality of the flavorant container is a marking on the container that indicates a flavor of the flavorant.

11. The beverage dispenser of claim 10 , wherein the flavorant container sensor is a bar code reader.

12. The beverage dispenser of claim 9 , wherein the flavorant container sensor is adapted to sense a shape of a portion of the flavorant container.

13. The beverage dispenser of claim 9 , wherein the detected quality of the unfiltered water is water hardness.

14. The beverage dispenser of claim 9 , wherein the detected quality of the unfiltered water is a level of an impurity.
