[0018] It should be appreciated that aspects of the invention disclosed herein are not limited in application to the details of the construction and the arrangement of components set forth in the following description or illustrated in the drawings. Further, the concepts disclosed herein may be arranged in any suitable combination, as the present disclosure is not limited in this respect. Also, the terminology used herein is for the purpose of description and should not be regarded as limiting.

[0019] Blenders have been employed to mix, crush, puree, and / or emulsify food and / or beverage ingredients using blades or like blending attachments. In addition, frothers are utensils that have been employed to agitate and aerate food and / or beverage ingredients using whisks or similar frothing attachments to allow for such ingredients to become foamed. However, conventional devices do not provide the capability to both blend and froth food and / or beverage ingredients as desired by the user. The inventors have found that there are difficulties in providing a mixing accessory which is both rigid enough to blend and break certain ingredients (e.g., ice) but that also is capable of agitating ingredients enough to froth. For example, in a mixing device configured for use in both blending and frothing, the mixing device may need to break up ice while also aerating steamed milk to froth the milk. Traditionally, these functionalities are provided by separate devices: a blender which uses blades to break up the ice and a milk frother which uses a fragile whisking attachment to aerate and froth the milk.

[0020] In view of the above, the inventors have identified a need for a mixing device which can both blend and froth food and / or beverage ingredients as desired by the user. The inventors have also appreciated that such embodiments of a mixing device may be integrated into beverage machines to provide a variety of beverage experiences to an end user, e.g., to form beverages with frothed milk as disclosed herein.

[0021] According to one aspect of the invention, the inventors have recognized that a mixing device may include a mixing attachment configured for use in both blending and frothing ingredients. In some embodiments, the mixing attachment may include both a blade attachment and a frothing component (e.g., a whisk) which are operatively coupled to one another and to a motor such that the motor drives the blade attachment and the 12083807.1 #14413940vlfrothing component simultaneously. In some embodiments, the frothing component may be part of the blade attachment. In other words, the blade attachment may include the frothing component incorporated with the blade attachment. For example, the blade attachment may include one or more holes in the blade, one or more angled portions, one or more protuberances, or any other suitable frothing component as the disclosure is not so limited. In some embodiments, the frothing component may be a frothing attachment that is separate and distinct from the blade attachment. For example, the frothing attachment may be a separate whisk attachment, where the frothing attachment and the blade attachment can be independently removable from the mixing device.

[0022] According to another aspect of the invention, the inventors have recognized that a mixing device configured for use in both blending and frothing may include a blade attachment and a frothing attachment which are interchangeable within the mixing device. That is, in some embodiments, a motor may operatively couple to one of the blade attachment and the frothing attachment at a time to blend and froth the ingredients within the mixing device, respectively. For example, each of the blade attachment and the frothing attachment may be keyed onto an output shaft of the motor such that the attachments can be interchanged by the user when blending or frothing is respectively needed.

[0023] As used herein, the term “ingredients” is intended to encompass food and / or beverage ingredients of any suitable type as the disclosure is not so limited. In some embodiments, suitable ingredients that may be used with the blade attachment and / or the frothing component of the mixing device may include, but is not limited to ice, milk, coffee, tea, sugar, salt, fruits, vegetables, yogurt, oils, or any other suitable ingredient as the disclosure is not so limited. For example, the frothing component may be used to froth any suitable type of milk including, but not limited to dairy milk, plant-based milk, soy milk, oat milk, almond milk, coconut milk, cashew milk, walnut milk, or any other suitable milk type.

[0024] In some embodiments, the mixing device may include one or more integrated heating elements configured to heat the one or more ingredients contained within the mixing device. The inventors have recognized that by providing an integrated heating element, a wider array of hot and cold food and beverage products may be produced by the mixing device. In some embodiments, the heating element may be selectively activated by a user when it is desirable to form a hot beverage or otherwise utilize heat. For example, the user may activate the heating element to steam milk, and the steamed12083807.1#14413940vlmilk may then be frothed by a frothing component according to embodiments disclosed herein to provide frothed milk, which may be used to form a variety of different beverages, such as a latte or a cappuccino. While such an example is disclosed, the heating element may be activated when desired for use in forming any suitable food and / or beverage product as the disclosure is not so limited. In some embodiments, a controller and one or more processors may be used to activate and / or deactivate the heating element as needed, while also controlling the temperature of the heating element to heat the ingredients to a desired temperature. For example, one or more temperature sensors may be disposed in a vessel of the mixing device where one or more ingredients are contained, and the one or more temperature sensors may be in communication with the heating element and controller such that the degree of heating provided to the ingredients by the heating element may be regulated.

[0025] In some embodiments, the heating element according to embodiments disclosed herein may be of any suitable type including, but not limited to, electrical resistance heating elements, induction heating elements, or any other suitable heating element as the disclosure is not so limited. While embodiments disclosed herein primarily discuss embodiments of a mixing device with an integrated heater, in some embodiments the mixing device may not include a heater as the disclosure is not so limited.

[0026] In some embodiments, the rotational speed of the blade attachment may be selectively controlled to achieve a desired degree of blending of the ingredients chosen by a user. Similarly, the rotational speed of the frothing component may be selectively controlled to achieve a desired degree of frothing of the ingredients chosen by the user. In some embodiments, an electronic speed controller (ESC) may be operatively coupled to a motor to in turn control the rotational speed of the blade attachment and / or the frothing component. In some embodiments, the user may select a specific rotational speed of the blade attachment and / or the frothing component using a user interface (UI) (e.g., a graphical user interface), a potentiometer, or the like. In some embodiments, the user may select other operational parameters for blending and / or frothing the ingredients including, but not limited to, time of blending and / or frothing, spin profile of the blade attachment and / or frothing component (e.g., pulse, continuous, etc.).

[0027] In some embodiments, the blade attachment may be configured to rotate at a speed suitable to promote blending of a food and / or beverage ingredient. For example, in some embodiments, a range of between 18,000 RPM and 21,000 RPM may be used to blend ingredients such as ice. However, other speed ranges for the blade attachment are12083807.1#14413940vlalso contemplated including, but not limited to, greater than or equal to 100 RPM, 300 RPM, 500 RPM, 1,000 RPM, 2,000 RPM, 3,000 RPM, 4,000 RPM, 5,000 RPM, 6,000 RPM, 7,000 RPM, 8,000 RPM, 9,000 RPM, 10,000 RPM, 11,000 RPM, 12,000 RPM, 13,000 RPM, 14,000 RPM, 15,000 RPM, 16,000 RPM, 17,000 RPM, 18,000 RPM, 19,000 RPM, 20,000 RPM, 21,000 RPM, 22,000 RPM, 23,000 RPM, 24,000 RPM, 25,000 RPM, or greater as the disclosure is not so limited. Likewise, in some embodiments, a suitable speed of the blade attachment may be less than or equal to 35,000 RPM, 34,000 RPM, 33,000 RPM, 32,000 RPM, 31,000 RPM, 30,000 RPM, 29,000 RPM, 28,000 RPM, 27,000 RPM, 26,000 RPM, 25,000 RPM, 24,000 RPM, 23,000 RPM, 22,000 RPM, 21,000 RPM, 20,000 RPM, 19,000 RPM, 18,000 RPM, 17,000 RPM, 16,000 RPM, 15,000 RPM, or lesser as the disclosure is not so limited. Suitable speed ranges made from combinations of the foregoing are also contemplated. For example, suitable speed ranges may include, but are not limited to, between 15,000 RPM and 25,000 RPM (inclusive), between 16,000 RPM and 23,000 RPM (inclusive), between 17,000 RPM and 22,000 RPM (inclusive), between 17,500 RPM and 21,500 RPM (inclusive), between 18,000 RPM and 21,000 RPM (inclusive), between 18,500 RPM and 20,500 RPM (inclusive), between 19,000 RPM and 20,000 RPM (inclusive), or any other suitable speed range.

[0028] In some embodiments, the frothing component may be configured to rotate at a speed suitable to enhance frothing of a beverage ingredient. For example, in some embodiments, a range of between 3,000 RPM and 4,000 RPM may be used for milk frothing. However, other speed ranges of the frothing component are contemplated including, but not limited to greater than or equal to 100 RPM, 300 RPM, 500 RPM, 1,000 RPM, 2,000 RPM, 3,000 RPM, 4,000 RPM, 5,000 RPM, 6,000 RPM, 7,000 RPM, 8,000 RPM, 9,000 RPM, 10,000 RPM, 11,000 RPM, 12,000 RPM, 13,000 RPM, 14,000 RPM, 15,000 RPM, 16,000 RPM, 17,000 RPM, 18,000 RPM, 19,000 RPM, 20,000 RPM, 21,000 RPM, 22,000 RPM, 23,000 RPM, 24,000 RPM, 25,000 RPM, or greater as the disclosure is not so limited. Likewise, in some embodiments, a suitable speed of the frothing component may be less than or equal to 35,000 RPM, 34,000 RPM, 33,000 RPM, 32,000 RPM, 31,000 RPM, 30,000 RPM, 29,000 RPM, 28,000 RPM, 27,000 RPM, 26,000 RPM, 25,000 RPM, 24,000 RPM, 23,000 RPM, 22,000 RPM, 21,000 RPM, 20,000 RPM, 19,000 RPM, 18,000 RPM, 17,000 RPM, 16,000 RPM, 15,000 RPM, or lesser as the disclosure is not so limited. Suitable speed ranges made from combinations of the foregoing are also contemplated. For example, suitable speed ranges may include,12083807.1#14413940vlbut are not limited to, between 1,000 RPM and 10,000 RPM (inclusive), between 2,000 RPM and 8,000 RPM (inclusive), between 2,000 RPM and 5,000 RPM (inclusive), between 2,500 RPM and 4,500 RPM (inclusive), between 3,000 RPM and 4,000 RPM (inclusive), between 3,200 RPM and 3,8000 RPM (inclusive), or any other suitable speed range.

[0029] The inventors have recognized that the rotational speed of the blade attachment and / or the frothing component may be adjusted according to the types of ingredients in the mixing device to optimize the quality of the blended and / or frothed product. In particular, ingredient characteristics such as temperature and ingredient type (e.g., milk content, sugar content, etc.) may affect the quality of the blended and / or frothed product. For example, it may be more difficult to aerate hot, steamed milk than it would be to aerate cold milk, and thus the frothing component may selectively rotate at a higher speed to froth steamed milk.

[0030] In some embodiments, the design of the blade attachment and / or the frothing component may also be selectively chosen according to the characteristics of the ingredients in the mixing device to optimize the quality of the blended and / or frothed product. For example, a whisk attachment may be used for frothing in conjunction with a blade attachment. However, such a whisk attachment may be too fragile to be used when also providing breakage to ingredients such as ice. Accordingly, in some instances, a blade with incorporated frothing holes or like features may be used to decrease risk of damage to the mixing attachment while still blending or frothing the ingredients in the mixing device. Without wishing to be bound by theory, the inventors have developed a variety of blade attachment and frothing component designs which are described in greater detail below and which may be selected depending on the types of ingredients that need to be blended and / or frothed.

[0031] In some embodiments, the mixing device according to embodiments disclosed herein may be employed for use in combination with a beverage machine rather than functioning as a standalone mixing device. That is, a beverage machine, e.g., a brewing machine for coffee-type beverages, may include an integrated mixing device disclosed herein for both blending and frothing. For example, a user may select options from the beverage machine to brew an iced coffee beverage including frothed milk, and the blade attachment may be used to blend ice while the frothing component may be used to froth milk which may also be steamed via the heating element. While such an example is disclosed, the blade attachment and frothing component of the mixing device may be 12083807.1 #14413940vlincorporated into a beverage machine to provide any suitable blended and / or frothed beverage as the disclosure is not so limited.

[0032] As disclosed herein, in some embodiments, the mixing device may include a singular motor to drive the blade attachment and / or the frothing component. That is, the singular motor may drive both the blade attachment and the frothing component simultaneously, or the singular motor may drive only one of the blade attachment and the frothing component at a time (e.g., the blade attachment and frothing attachments may be interchangeable within the mixing device). In other embodiments, however, more than one motor may be used, e.g., each of the blade attachment and frothing attachments may be coupled to a respective motor to drive each of the attachments within mixing device as the disclosure is not so limited. The blade attachment and frothing attachments may also be coupled to the motor in any suitable fashion including, but not limited to, being keyed onto an output shaft of the motor, being threadingly engaged to an output shaft of the motor, being secured onto the output shaft of the motor via a fastener, or any other suitable means of engagement as the disclosure is not so limited.

[0033] In some embodiments, both the blade attachment and the frothing component may be driven simultaneously by a motor as disclosed herein. In some such embodiments, the frothing attachment may be positioned above or below with respect to the blade attachment as the disclosure is not so limited. In some embodiments, multiple blade attachments and / or multiple frothing components may be included within the mixing device. For example, a first frothing attachment may be positioned above a blade attachment and a second frothing attachment may be positioned below the blade attachment. In another example, a first blade attachment may be positioned above a frothing attachment and a second blade attachment may be positioned below the frothing attachment. While such examples are disclosed, a plurality of blade attachments and / or frothing components may be arranged in any suitable fashion as the disclosure is not so limited. In addition, the blade attachment and frothing components may be constructed in a variety of suitable designs as detailed below which will influence their characteristics such as breakage and blending ability, aeration ability for frothing, structural integrity, etc.

[0034] Turning to the figures, specific non-limiting embodiments are described in further detail. It should be understood that the various systems, components, features, and methods described relative to these embodiments may be used either individually 12083807.1 #14413940vland / or in any desired combination as the disclosure is not limited to only the specific embodiments described herein.

[0035] FIG. 1 shows a schematic front view of a mixing device 100. The mixing device 100 may include a vessel 110 and a housing base 120, where the vessel 110 may be removably coupled to the housing base 120. As disclosed herein, ingredients may be received within the vessel 110, and a blade attachment and / or a frothing component (not shown) may be disposed within the vessel 110. In some embodiments, the mixing device 100 may include safety features that prevent the mixing device from operating when the vessel is not secured to the housing base. In addition or alternatively, the mixing device may include an indicator (e.g., an LED indicator, audible alarm, etc.) to indicate to a user that the vessel is not properly secured to the housing base.

[0036] The housing base 120 may include an adjustment knob 121 that is configured to adjust a degree of blending or frothing of the blade attachment and the frothing component, respectively. The user may turn the adjustment knob between various setting as indicated by markings 122. For example, the markings may read “Off’, “Cold Froth”, and “Hot Froth”, although other markings and settings are contemplated. For example, for blending, the markings may read indicia such as “pulse”, “grate”, “blend”, “liquefy”, “shred”, “grind”, “ice crush” or any other suitable markings as the disclosure is not so limited. Likewise, for frothing, the markings may read indicia such as “low froth”, “medium froth”, “high froth”, or indicia corresponding to a setting for the ingredient type such as “dairy milk”, “almond milk”, “oat milk”, or any other suitable markings as the disclosure is not so limited. Accordingly, such markings may correspond to a setpoint rotational speed of the blade attachment and / or the frothing component which may allow for the user to have a wider discretion in selecting a desired degree of blending and / or frothing of the ingredients. In some embodiments, the rotational speed of the attachments may be directly indicated as the markings 122 (e.g., 18,000 RPM, 19,000 RPM, 20,000 RPM, 21,000 RPM, High, Medium, Low, etc.). In some embodiments, the user may enter on a digital display of the mixing device a desired rotational speed of the attachments (e.g., 18,500 RPM) to optimize the user’s preferred quality of the blended or frothed product.

[0037] While not shown in the embodiment of PIG. 1, a motor may be located within the housing base 120, and the motor may be operatively coupled to the blade attachment and / or the frothing component positioned within the vessel 110 (not shown). A heating element may also be positioned within the vessel 110 or the housing base 120 to heat the 12083807.1 #14413940vlingredients received within the mixing device 100. One or more electrical connections 123, 124, 125 may be received in part within the housing base 120 for functionalities such as powering the motor, powering the heating element, communication with a controller and one or more processors for controlling the operation of the mixing device, or for other suitable functionalities.

[0038] FIGs. 2-3 show schematic diagrams of two different embodiments of a mixing device 200, 300. Specifically, FIG. 2 shows an arrangement where the blade attachment and frothing component are combined into a singular mixing attachment 230 while FIG. 3 shows an arrangement where the blade attachment 330 and the frothing attachment 331 are interchangeable within the mixing device 300.

[0039] In FIG. 2, the mixing device 200 may include a vessel 210 and a housing base 220 which are coupled to one another. The vessel 210 may be removable from the housing base 220 such that ingredients may be received within the vessel 210. As shown in FIG. 2, a combination blade and frothing mixing attachment 230 may be received within the vessel 210, and the mixing attachment 230 may be actuated to blend and / or froth the ingredients within the vessel 210.

[0040] As disclosed herein, the combination blade and frothing attachment 230 may have a variety of suitable designs. For example, the blade attachment may include one or more angled portions to facilitate frothing. In another example, the frothing component may comprise one or more holes formed in the blade attachment, one or more protuberances formed in the blade attachment, or any other suitable frothing features.That is, in some embodiments, the mixing attachment may not include a separate frothing attachment. In other embodiments, the combination blade and frothing attachment 230 may include both a blade attachment and a separate frothing attachment which are operatively coupled to one another. For example, a frothing attachment (e.g., a frothing wheel) may be positioned above or below the blade attachment, and both the blade and the frothing attachment may be operatively coupled to a motor to be simultaneously driven by the motor.

[0041] As shown in FIG. 2, in some embodiments, the housing base 220 may include a heater base 240, a motor 250, and one or more electrical connections 260. The heater base 240 may include a heating element that is configured to heat one or more ingredients received within the vessel 210. For example, the heating element may be an electric resistive heating element configured to, e.g. steam milk within the vessel 210. The motor 250 may be operatively coupled to the combination blade and frothing attachment 23012083807.1#14413940vldetailed above such that the motor may drive both the blade attachment and the frothing component of the attachment 230 simultaneously. The one or more electrical connections 260 may be used for functionalities such as powering the motor, powering the heating element, communication with a controller and one or more processors for controlling the operation of the mixing device 200, etc. In some embodiments, the heating element, the motor, a controller and / or one or more processors, and / or other components of the mixing device may be powered using mains electricity. In other embodiments, however, such components may be powered using a portable power source (e.g., batteries, etc.).

[0042] In FIG. 3, the mixing device 300 may include a vessel 310 and a housing base 320 which are coupled to one another. Similar to FIG. 2, the vessel 310 may be removable from the housing base 320 such that ingredients may be received within the vessel 310. As shown in FIG. 3, the vessel may include a blade attachment or a frothing attachment, which may be interchanged with one another as necessary for a blending or frothing application, respectively. In some embodiments, the blade attachment and the frothing attachment may be configured to removably couple with a motor 350 to allow for the attachments to be interchanged. For example, the blade attachment 330 and frothing attachment 331 may be keyed onto an output shaft of the motor, be threadingly engaged to an output shaft of the motor, be secured onto the output shaft of the motor via a fastener, or any other suitable means of engagement. In some embodiments, one of the blade attachment 330 or the frothing attachment 331 may be received within the vessel 310, and the attachment may be actuated to blend or froth the ingredients within the vessel 310.

[0043] As disclosed herein, the interchangeable blade attachment 330 and the interchangeable frothing attachment 331 may have a variety of suitable designs. The interchangeable blade attachment may be of any suitable shape. For example, the blade may have a flat shape, a curved shape, a flat base with curved ends, a flat base with one or more angled portions, or any other suitable shape as the disclosure is not so limited. In some embodiments, the blade attachment may include a plurality of blades. That is, each blade attachment may include 1, 2, 3, 4, 5, 6, or more blades extending outwardly from a central portion of the blade attachment. In some embodiments, the mixing device may include a mixing attachment having a plurality of blade attachments. For example, the mixing attachment may include a first blade attachment, a second blade attachment, and a frothing component. In such an example, the first blade attachment may have a first number of blades and be positioned above the frothing component while the second blade 12083807.1 #14413940vlattachment may have a second number of blades and be positioned below the frothing component.

[0044] The interchangeable frothing attachment may also be of any suitable shape. For example, the frothing attachment may be a whisk, a disc with one or more protruding ribs extending therefrom, or any other suitable shape as the disclosure is not so limited. In some embodiments, the mixing device may include a mixing attachment having a plurality of frothing attachments.
