DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, a schematic view of an exemplary embodiment of the beverage infuser assembly in accordance with the disclosure is shown in FIG. 1 and is designated generally by reference character 100. Other embodiments of beverage infuser assembly 100 in accordance with the disclosure, or aspects thereof, are provided in FIGS. 2-6 as will be described. The systems and methods described herein provide for an accelerated beverage infuser. The systems and methods described herein act to reduce the infusion time needed for preparing certain beverages, e.g., hot and cold coffee, hot and cold tea, fruit, herb, spice infused liquids, or the like, and any combination thereof.

[0025] As shown in FIGS. 1-2, a beverage infuser assembly 100 includes a fluid vessel 102 having a top end 103 and a bottom end 104. A longitudinal axis A is defined between top end 103 and a bottom end 104. Infuser assembly 100 includes a base assembly 106 operatively connected to bottom end 104 of fluid vessel 102. Base assembly 106 includes an upper isolation platform 120, a lower housing 122 and elastomer elements 124, e.g. rubber grommets, between upper isolation platform 120 and lower housing 122. Elastomer elements 124 act to provide noise isolation and vibration dampening to lower housing 122, described in more detail below.

[0026] With reference now to FIGS. 3-4, fluid vessel 102 includes a first threaded portion 132 and base assembly 106 includes a second threaded portion 134. First and second threaded portions 132 and 134, respectively, are configured and adapted to engage or disengage one another to allow for fluid vessel 102 to be removable from base assembly 106. A vibration source 108 is positioned within base assembly 106. Vibration source 108 generates ultrasonic waves, e.g., those with a frequency of 20 kHz and higher, that are used to increase infusion. This is an advantage over other systems that may use rotational and/or percolating flow as the infusion ingredient does not have to be a fine particulate, it can be fruit infusion, for example. Overall, the expected improved extraction speed due to the ultrasonic energy provided is 30 to 50% faster than traditional units.

[0027] As shown in FIGS. 4-5, upper isolation platform 120 includes a mounting portion 130 that extends downward from a lower surface 117 of isolation platform 120. Vibration source 108 is mounted within mounting portion 130 of isolation platform 120. Elastomer elements 124 are positioned between lower surface 117 of isolation platform 120 and a top surface 119 of lower housing 122 and can be threaded into place by one or more fasteners 121 that are positioned through apertures 123 in isolation platform and corresponding apertures 125 in lower housing 122. Elastomer elements 124 positioned in this way act to provide noise isolation and vibration dampening to lower housing 122 by ensuring that the vibration generated by vibration source 108 is not transmitted to lower housing 122. Upper isolation platform 120 is coupled to each elastomer element 124 and lower housing 122 via respective fasteners 124.

[0028] With continued reference to FIGS. 4-5, base assembly 106 includes a mounting frame 128 operatively coupled to lower housing 122. Beverage infuser 100 includes at least one battery 138 mounted within a portion of mounting frame 128. Assembly 100 includes a battery charge controller printed circuit board (PCB) 140. Battery 138 is operatively connected to mounting frame 128. Battery is a rechargeable battery and allows for portability without the need for an external power source. Rechargeable battery 138 allows for the ability to infuse beverages within a cold environment (e.g., a refrigerator). Lower housing 122 can include a USB charging port 127, or the like, in order to provide power to rechargeable battery 138 during recharging. Those skilled in the art will readily appreciate that, in certain embodiments, instead of rechargeable battery, a corded electrical connection can be utilized with beverage infuser 100, similar to electrical cord 215, described below.

[0029] With continued reference to FIGS. 1-4, vibration source 108 is configured and adapted to transmit ultrasonic waves into fluid vessel to accelerate the infusion process. In the embodiment of FIGS. 1-2, vibration source 108 is an electric motor 108. Electric motor 108 is an eccentric rotating mass vibration motor having eccentric weight 129. Motor 108 with eccentric weight 129, provides ultrasonic energy into fluid vessel 102. Beverage infuser 100 includes an on/off switch 137 to turn electric motor 108 on or off. Beverage infuser 100 includes a dial 136 operatively coupled to electric motor 108 via control circuitry, e.g., on a PCB 139, in order to allow for the vibration strength of electric motor 108 to be adjusted depending on the type of desired infusion. PCB 139 includes a controller 144 operatively connected thereto or thereon.

[0030] As shown in FIG. 4, the controller 144 can be or include a motor controller configured to adjust the speed of motor 108 and/or the frequency of energy being input into assembly 100 based on a user selection on dial 136. The user selection can be a specific speed and/or frequency or be a pre-defined program. For example, depending on the desired application or type of ingredient, the frequency of vibration emitted by electric motor can range from 20 kHz and higher. Dial 136 and PCB 139 allow for a user to actively and precisely control extraction into liquids via antenna 118 and adjust the vibration frequency (traditional units in the market only control infusion strength by duration of the infusion cycle). PCB 139 can also include a time control function to stop after a certain duration of the switch being on. The controller 344 can include a memory 149, the memory 149 configured to store the predefined program. The predefined program includes at least one of a respective type of infusion ingredient, a respective type of preparation for a respective type of infusion ingredient, or a respective timing for a respective type of preparation.

[0031] With continued reference to FIGS. 1-4, beverage infuser includes a plunger assembly 110 including a plunger rod 111 having a first end 112 and a second end 114. Plunger assembly 110 includes a plunger filter 116 positioned on second end 114 of plunger rod 111. As shown in FIG. 1, in an infusion position, plunger filter 116 is positioned more proximate top end 103 of fluid vessel 102 than bottom end 104 of fluid vessel 102. Plunger filter 116 allows for filtering of infusion elements out of the beverage when process is complete. Plunger assembly 110 includes an antenna 118 positioned within fluid vessel 102 between plunger filter 116 and first end 112 of plunger rod 111. Antenna 118 is configured and adapted to amplify the ultrasonic energy transfer from motor 108 to facilitate efficient infusion. In a pouring position, as shown in FIG. 2, plunger filter 116 is positioned more proximate bottom end 104 of fluid vessel 102 than top end 103 of fluid vessel 102. In this way, plunger filter 116 pushes the ingredient (e.g. coffee grounds, fruit, tea leaves, or the like) toward the bottom end 104 of fluid vessel 102. This allows the infused fluid (which is not pushed downward) to be properly poured from fluid vessel 102.

[0032] As shown in FIG. 6, another embodiment of a beverage infuser assembly 200 is shown. Beverage infuser assembly 200 is similar to beverage infuser assembly 100 in that it includes a vibration source 208, similar to vibration source 108. Vibration source 208 is shown as an eccentric electric motor. But beverage infuser assembly 200 includes a fluid vessel 202 where a bottom end 204 is fixed to base assembly 206. Vibration source 208 is shown out of place for sake of clarity. As shown with broken lines in base 206, the vibration source would be operatively coupled to assembly 200 within base 206. Additionally, base assembly 206 includes an electric port 233 configured and adapted to receive an electrical cord 215 coupled to an external power source. In beverage infuser assembly 200, there is no antenna utilized, nor are there elastomeric elements, e.g., elastomeric elements 124, utilized in base assembly 206.

[0033] With continued reference to FIG. 6, the base assembly 206 includes a single housing 209, without a separate isolation platform and lower base. Housing 209 includes a support platform 217. Vibration source 208 is mounted to downward facing surface of support platform 217. A mounting portion, similar to mounting portion 130, can be used to mount vibration source 208 onto support platform 217. The functionality of vibration source 208 and reduced infusion time described for assembly 100 is the same as that for assembly 200. In some embodiments, beverage infuser 200 includes a dial 236 operatively coupled to electric motor 208 via a motor speed controller PCB 239 in order to allow for the vibration strength of electric motor 208 to be adjusted depending on the type of desired infusion, similar to dial 136 and PCB 139, described above. Assembly 200 may also include an on/off switch 237, similar to switch 137 described above. Those skilled in the art will readily appreciate that, in some embodiments of assemblies 100 or 200, dials 136 and 236 may not be included, and only on/off switches 137 and 237 may be used. Beverage infuser assembly 200 also includes a plunger assembly 210 including a plunger rod 211 having a first end 212 and a second end 214. Plunger assembly 210 includes a plunger filter 216 positioned on second end 214 of plunger rod 211. Plunger filter 216 is the same as plunger filter 116 and provides the same filtering function as described above for plunger filter 116.

[0034] In accordance with certain embodiments, a method for infusing a beverage with one or more ingredient includes actuating a vibration source, e.g., electric motor 108 or 208, positioned within a base assembly, e.g., base assembly 106 or 206, of a beverage infuser, e.g., beverage infuser 100 or 200. The method includes transmitting ultrasonic waves generated by the vibration source into a fluid vessel, e.g., fluid vessel 102 or 202, of the beverage infuser to accelerate infusion of one or more ingredient within the fluid vessel into a fluid within the fluid vessel. In certain embodiments, the vibration source is actuated, e.g., turned on, for 15 minutes. In some embodiments, the vibration source is actuated for 10-15 minutes, or 10-12 minutes. This actuation accelerates the infusion process of an ingredient into the fluid, reducing the time it takes for a user to make the desired infused beverage, e.g., cold-brew coffee, or the like. Once the infusion into the fluid is complete, the method includes sliding a plunger assembly, e.g., plunger assembly to filter the at least one ingredient to one side of the fluid vessel.

[0035] As will be appreciated by those skilled in the art, aspects of the present disclosure may be embodied as a system, method or computer program product. Accordingly, aspects of this disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.), or an embodiment combining software and hardware aspects, all possibilities of which can be referred to herein as a “circuit,” “module,” or “controller.” A “circuit,” “module,” or “controller” can include one or more portions of one or more separate physical hardware and/or software components that can together perform the disclosed function of the “circuit,” “module,” or “controller”, or a “circuit,” “module,” or “controller” can be a single self-contained unit (e.g., of hardware and/or software). Furthermore, aspects of this disclosure may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.

[0036] Those having ordinary skill in the art understand that any numerical values disclosed herein can be exact values or can be values within a range. Further, any terms of approximation (e.g., “about”, “approximately”, “around”) used in this disclosure can mean the stated value within a range. For example, in certain embodiments, the range can be within (plus or minus) 20%, or within 10%, or within 5%, or within 2%, or within any other suitable percentage or number as appreciated by those having ordinary skill in the art (e.g., for known tolerance limits or error ranges).

[0037] The articles “a”, “an”, and “the” as used herein and in the appended claims are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article unless the context clearly indicates otherwise. By way of example, “an element” means one element or more than one element.

[0038] The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

[0039] As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e., “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.”

[0040] Any suitable combination(s) of any disclosed embodiments and/or any suitable portion(s) thereof are contemplated herein as appreciated by those having ordinary skill in the art in view of this disclosure.

[0041] The methods and systems of the present disclosure, as described above and shown in the drawings, provide for improved beverage infusers with superior properties including reduced infusion time at room temperature or refrigerated temperature and reduced cost over traditional beverage infusers. The rechargeable battery allows for a smaller footprint, and portability. The systems and methods of the present invention can apply to cold-brew coffee, tea, or the like. While the apparatus and methods of the subject disclosure have been shown and described with reference to preferred embodiments, those skilled in the art will readily appreciate that changes and/or modifications may be made thereto without departing from the scope of the subject disclosure.
