BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to method and a device to make a single or a multiple serving of a select flavored, carbonated beverage.
2. Description of the Related Art
A well known soda dispenser utilizes a large tank of carbon dioxide (“CO2”) to carbonate a number of individual fountain beverages. The CO2 is simultaneously added to both a branded soda-syrup and water dispensed from a spigot. Recipes for varied flavors are accomplished afterwards, wherein the bottled or the poured beverage is flavored by means of a sugared syrup.
Existing carbonating devices introduce CO2 into a one liter or two liter bottle of water or juice by means of a single, one use cartridge or a larger cylinder for multiple engagements of CO2. A flavor can be added after the liquid is carbonated. The contents are poured into a glass or drunk from the liter bottles.
These devices cannot make multiple beverage types at the same time.
The consumer demands a healthy alternative to those sugary soft drinks and is willing to pay for the convenience of having a beverage that's healthy, portion controlled (single-serving glass) to avoid unnecessary waste with continual freshness, always cooled, made to one's specific taste by regulating and controlling the beverage temperature, carbonation level, type of beverage, and specific flavor and amount of flavor. These consumer demands are seen in parallel to the coffee consumer. They have demanded and now have coffee makers that make a single-serving cup, always fresh and have the ability to customize the individual's taste my controlling the strength of the flavor and type of flavor and type of beverage, e.g.: regular coffee, cappuccino, lattes, etc. On demand, continual freshness with a push of a button. Now the soft drink, sparkling flavored water and sparkling juice consumer want the same choices and are willing to pay for those conveniences.
Finally responding to the cries of the consumer that sugary beverages are causing major health problems and the cause of obesity, many school districts across the country are removing these beverages from their premises and only allowing health beverages. In response, beverage companies plan on introducing a beverage that low in sugar and fortified with vitamins and minerals.
An emerging health conscience lifestyle demands flavorful alternatives to sugary soft drinks. Consumers are more attentive to healthy portions and they prefer the convenience of a sparkling, fresh, cool beverage made at home. The present invention teaches a sparkling beverage maker that provides a means to select a flavor, to select an amount of flavor, to control the carbonation level, to control the chilled temperature and to select the type of beverage, e.g., a sparkling water, a sparkling soda or a sparkling juice. The present invention provides a means for a person to repeatedly and to consecutively make a number of different single-serving beverages at home.

As described below, a preferred embodiment, as anticipated at the time of filing, is identified and described as exemplary of the teachings of the present invention. However, the disclosure is not intended to be narrowly construed by this exemplary embodiment, as one skilled in the art would know that the operational and functional equivalent of many of the components, systems, steps and processes taught herein could be modified or replaced by equivalent components, systems, steps and processes and still remain within the spirit and teachings of the present invention.
1. Detailed Description of the Figures
A preferred embodiment of a select serving, flavored and/or sparkling beverage maker, hereinafter referred to generally as a sparkling beverage maker 10, is shown in FIG. 1-8. Both the front portion 12 is segmented generally into a control area 14, a mixing area 16, and a filling area 18. The control area 14 houses the carbonator 20, the chiller 22, and the operational control unit 24 which houses a Central Processing Unit, the operation of which is described in greater detail below. The mixing area 16 provides for the mixing of flavors, water, and carbonation, the operation of which is also described in greater detail below. The filling area 18 incorporates the water reservoir 30 and pumps to provide beverage mixing water for the creation of carbonated and non-carbonated, chilled flavored beverages.
In conjunction with FIGS. 5 and 7, the sparkling beverage maker 10 incorporates the Central Processing Unit, or CPU 50 for operationally controlling all of the internal controls. When the beverage maker 10 is activated, a user interface displaced on the operational control unit 24 will indicate status, cycle step and operation by use of illuminated LED driven directly from the internal power supply 54. Immediately afer power is applied the unit senses the present of the water within the water reservoir 30 through a water level sensor 56. In the enclosed example shown for purpose of enabling a preferred embodiment, the water reservoir 30 is anticipated as having a 64 ounce capacity and can be capable of containing a replaceable filter through which water will communicate. The use of a translucent chamber wall will allow for visual inspection of the remaining water capacity. The water level will be sensed in order to manage the fill/dispensing operations property, as disclosed below.
While a number of sensors are equivalent, a float sensor 56 will trip if the water level gets too low or the chamber is removed. Alternately or additionally, an infra red LED and IR sensitive transistor can also form a sensing function for the present of a properly seated reservoir containing liquid.
A first water pump 58 is used to move water from the reservoir 30 to the chiller 22. Under direct control of the CPU 50, the volume of water to be moved can be controlled as variable, or can be implemented as a constant volume feed for each cycle. Pumped to the chiller 22, the chiller 22 incorporates a thermoelectric cooler 59 that is used to chill the water to the prescribed temperature. Temperature is sensed by a positive temperature coefficient resistor 60 bonded to the chiller. As shown in conjunction with FIG. 6a through 6d, the chiller 22 utilizes a chiller box 22a forming an operative chilling volume 23 sealed by a chiller lid 22b such that the operative chilling volume 23 corresponds to a cycle volume for each chilled (or heated) beverage. As can be seen by one skilled in the art, the present teachings are similarly capable of chilling or heating the beverage through the use of a thermoelectric heat transfer unit. For use in cooling, a heat sink 62 on the ‘hot’ side allows fresh air to be forced across by a fan 63 under the control o the CPU 50. The fan 63 under control of the CPU, can be cycled on an off during operation.
A second water pump 70 is used to dispense the contents of the chiller through a flavor cup 100 as described in greater detail below. Dispensed under pressure, this second water pump 70 is operated after the chiller 22 is filled, reaches temperate, and is carbonated if so selected. This pump 70 will run slightly longer than necessary in order to fully dispense and purge the chiller 22, flavor cup 100 and all communicated operative plumbing.
2. Operational Overview
A select serving, flavored and/or sparkling beverage maker 10 of the present invention is a new appliance that that creates a new product category in the home appliance industry. Including the capacity for custom formulations of flavor for single cup/glass on demand dispensing, the dispenser 10 will incorporate a CO2 gas cylinder for selectively carbonating each beverage. To accomplish this, several features are anticipate. These include the following.
An air inlet check valve or chiller vent 102 must close to allow CO2 to be injected to the chiller during carbonation, and open under negative pressure from the second water pump 70 to allow air into the chamber 23 to allow the chiller contents to be pumped through the flavor cup 100 and eventually into the user's drinking container 112.
A water inlet check valve 102 is opened under positive pressure from the first water pump 58 to allow water to enter the chiller 22 from the water reservoir 30. When this pump is off, the valve 102 automatically closes to allow CO2 to be injected into the chiller 22.
A CO2 needle valve 106, functioning as carbonation control means, allows CO2 to enter the chiller 22 and carbonate the water prior to dispensing through the flavor cup 100. This feature is optional and is a function of a front panel control selection to the CPU. If carbonation is selected, the chiller 22 will be filled with water, less the volume of the flavor cup 100, and then the water check valve 104 closed. CO2 is optionally injected into the chiller, causing carbonation. This action may be delayed if the water temperature in the chiller has not reached the appropriate temperature.
A relief valve 108 is shown as a safety precaution against over-pressurizing the chiller form the CO2 source.
An output needle valve 112 is desired to resist CO, injection pressure during carbonation. It is opened under CPI control to allow dispensing, and closed during carbonation.
Finally, a CO2 Chamber 120 is required as a replaceable, disposable supply of carbonating gas. While various available or proprietary supplies are envisioned, the present invention in its preferred embodiment anticipates adapting to use commercially available chambers of a standard size that have been popularized by paint ball enthusiast. Such chambers are easy to acquire and already comprise a commercial infrastructure for economically efficient refilling.
3. Flavor Cups
As shown in FIG. 9a through 9c, the use of individually packed, single use disposable flavor cups 100 are anticipated which include a mixing area 100a of a volume greater than the volume that will be filled with the flavors of choice to make sparkling flavored water and a syrup to make vitamin fortified and mineral added, low sugar soda pop. By way of example, in the preferred embodiment a flavor cup 100 would have a capacity of slightly more than 1 oz, but will be filled with 1 oz. syrup flavor concentrate having a custom vacuum formed design to incorporate a indexing ridge 101, a sealed foil cover 103 covers and seals the flavor cup 100. When placed in the mixing chamber 12, the foil 103 is pierced on the top and, in doing so, will allow the cup to move downward and be pierced a second time from the bottom. An upper peripheral flange 105 therein support the cup. When the piercing needle approaches from the top of the cup, it will be engaged and sealed about its perimeter by the foil and around the piercing cite. The flavor cup 100 thereafter functions as a mixing chamber for carbonated or noncarbonated chilled water and flavor syrup.
4. Operation of the Preferred Embodiment
