Description

STOVETOP COFFEE BREWING DEVICE

CROSS-REFERENCE TO RELATED APPLICATIONS

[001] This application is a PCT application which claims priority to United States patent application serial no. 62/677,673 filed May 30, 2018, the contents of which are incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

[002] The present invention relates to stovetop coffee makers, specifically to such coffee makers which are used for making coffee beverages requiring high temperature and pressure.

BACKGROUND

[003] Many varieties of stovetop coffee makers are available. The majority of these coffee makers are based on the moka pot design which employs a lower heating container (boiler) and an upper collection container, whereby heated water moves upward by means of steam pressure through a funnel and into a perforated grounds basket containing the brewing media (coffee grounds) before continuing through a perforated plate (filter) and into to the collection chamber. While this brewing method produces a generally desirable coffee beverage brewed at approximately 2 bars (29 psi) of maximum pressure, it is unable to generate the 9 bars (l30psi) of pressure attained by modern espresso brewers and the pressure necessary to produce“true” espresso-style coffee, nor offer multiple brewing options for a multitude of coffee beverage results. [004] The applicant seeks to solve this inability by introducing an additional element to the existing moka pot brewing method that allows the operator to achieve the higher brewing pressures required of espresso and related coffee beverages, provide a multitude of brewing options by means of multiple brewing configurations, provide greater control of the brewing process and subsequent quality of the brewed beverage,. Because existing moka pot boiler designs may not be suited for the higher pressures the present application discloses a coffee maker of suitable capability to brew espresso beverages.

SUMMARY

[005] The following presents a simplified summary in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview, and is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

[006] In one aspect of various exemplary embodiments, a device for brewing coffee is provided, the device comprising a multi-chamber brewing assembly that mechanically couples with a boiler and collection container for the brewing of coffee beverages. A funnel apparatus in said brewing device directs the movement of heated water from the boiler into a pressurizing chamber by means of steam pressure. A mechanically coupled pressure gauge determines the optimal pressure for said heated water to move from the pressurizing chamber into a brewing chamber via a duct way by means of a release valve. Upon entering the upper brewing chamber, which contains a perforated basket for the placement of a determined amount of coffee media, the heated, pressurized water mixes with the coffee media to create a brewed beverage. Said brewed beverage is then directed by means of the established pressure through a perforated plate

(filter) to remove the coffee media (grounds) before entering the collection container, whereby a brewed beverage of determined brewing temperature and pressure is provided. By means of a separate, isolated duct way, steam created in the boiler is directed to a mechanically coupled steam wand for the purposes of both regulating internal brewing pressure as well as to steam milk for the purpose of creating cappuccino and espresso-style coffee beverages.

[007] In another aspect of various exemplary embodiments, a device for brewing coffee is provided, the device comprising a boiler for conducting heat from a stovetop to water contained therein and for containing heated water, pressurized water, and pressurized steam; a main housing removably coupled to the boiler, wherein the main housing contains and distributes the heated water and pressurized steam, comprising a boiler funnel, a lower grounds basket for containing coffee grounds, a water duct way in fluid communication with boiler funnel, a steam duct way that terminates into a pressure release valve, the steam duct way in fluid

DETAILED DESCRIPTION

[0017] In the following detailed descriptions of various exemplary embodiments, reference is made to the accompanying drawings that form a part hereof, and in which is shown, by way of illustration, specific embodiments that may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present disclosure.

[0018] FIG. 1 illustrates an embodiment of the device’s cylindrical main housing (1)

mechanically coupled with a moka pot style boiler (2) and a moka pot style collection container (3) by means of matching threads extending around the lower bottom interior and upper top exterior of said main housing (1), respectively. A flanged, cylindrical boiler funnel (4) allows heated and steam-pressurized water to flow upward through a cylindrical boiler gasket (5), which may be made of an elastomer material that is compatible and resists high temperature water and steam in order to seal said boiler (2). In an embodiment, the gasket (5) is nested in the cylindrical area between said main housing (1) and said boiler (2).

[0019] As illustrated in FIG. 2, the flange of said boiler funnel (4) and said boiler gasket (5) may be perforated at regular intervals along their circumferences to allows the passage of steam from said boiler (2) to a steam head reservoir (15) in the lower portion of said main housing (1) without compromising the sealed nature of the boiler (2). Said main housing (1), which is made of metal, preferably stainless steel, comprises several integrated features. First, there is a centrally placed vertically oriented cylindrical funnel (7) rising from the bottom of said pressurizing chamber (6) for passing heated and steam-pressurized water into said chamber (6). The pressurizing chamber (6) and the cylindrical funnel (7) may also be described as being in fluid communication with each other. Second, there may exist a steam duct way (16) for the passage of steam from the steam head reservoir (15) to an external, mechanically coupled steam wand assembly (17) (see FIG. 3). Third, there may be an cylindrical housing (20) for the insertion of a lower grounds basket (28) and a upper brewing assembly (18), wherein there may be an integral, horizontally-oriented interior flange (21) for securing said upper brewing assembly (18) and a rectangular, vertically-oriented interior flange (22) for aligning said upper brewing assembly (18). Fourth, there may be a peripherally oriented water duct way (10) for directing or distributing water (hereinafter referred to as being in fluid communication) from the pressurizing chamber (6) to said upper brewing assembly (18). While metals other than stainless steel (such as aluminum) may be utilized for manufacturing said main housing (1) and associated features described in FIGs 1-3, stainless steel is preferred due to its high strength, heat conductivity, corrosion resistance, and compatibility with multiple forms of manufacturing processes. Mechanically coupled to said pressurizing chamber (6) of said main housing (1), may be a pressure gauge assembly (8) with an effective measurement range of up to 16 Bars (232 psi) for the measurement of water pressure within said pressurizing chamber (6). Mechanically coupled into the ingress of water duct way (10), may be a manual or automated release valve assembly (9) which is made of metal, preferably stainless steel, for the regulated passage of heated water of a predetermined amount of pressure, for example, 9 bars (130 psi).

[0020] Also as illustrated in FIG. 2, said lower grounds basket (28) which is made of metal, preferably stainless steel, comprises an integral, centrally placed inverted cylindrical funnel matching the outer diameter of said main housing cylindrical funnel (7) and rising vertically from a sloped bottom surface that matches the degree of angle of said main housing pressurizing chamber (6). The basket (28) also comprises an integral recess for accommodating said main housing integral steam duct way (16) and an integral, cylindrical, perforated outer housing.

[0021] Also as illustrated in FIG. 2, said upper brewing assembly (18) comprises a cylindrical upper brewing chamber (11) which is made of metal, preferably stainless steel, that includes a vertically-oriented channel (23) for the purpose of alignment, a single perforation of a size and placement that matches the egress of said water duct way (10) for the unobstructed passage of heated and pressurized water from said pressurizing chamber (6). An upper grounds basket (12) which is made of metal, preferably stainless steel, comprises an upper flange for proper placement upon inserting into said upper brewing chamber (11). The basket (12), into which the coffee media is placed, mates with a perforated cylindrical plate (14), each of which may be made of metal, preferably stainless steel, to prevent the passage of coffee media into said collection container (3) (see FIG 3). Between the basket (12) and the plate (14), resides a cylindrical upper gasket (13) which is made of high temperature water and steam resistant elastomeric material to seal said brewing assembly against said collection container (3). [0022] As illustrated in FIG 3, an embodiment of the device shown in FIG. 1-2 is depicted with brewing media (water and coffee), which further illustrates a method whereby heated water passes through coffee media twice under low to moderate pressure to produce a brewed coffee beverage. In this configuration example, the boiler (2) is filled with an amount of water (Al), for example about 355ml, or 12 fluid ounces. The flange of the cylindrical boiler funnel (4) along with the boiler gasket (5) are nested in the cylindrical recess at the bottom of the main housing (1) and the main housing is threadedly coupled, or otherwise removably coupled, to the boiler (2) and tightened to form a pressurizable seal. The lower grounds basket (28) is filled with an amount of moderately packed, medium ground coffee media (Cl), for example 20 grams, and inserted into the pressurizing chamber (6) of the main housing (1). The upper grounds basket (12) is filled with an amount of moderately packed, medium ground coffee media (C2), for example 16 grams. The brewing assembly (18) is positioned within the upper portion of the main housing (1) and then threadedly coupled, or otherwise removably coupled, to the collection container (3) and tightened to form a seal using the pressurizable gasket (13).

[0023] The complete brewing assembly (19) is heated on a stovetop burner, or other appropriate heating element. While the stovetop burner or appropriate heating element utilized will not affect the required configuration of the present invention, it may affect the method of brewing. For instance, since brewing on an induction burner would generate the requisite heat (thus steam pressure) faster than a gas-based burner, the user would be advised to monitor and/or regulate the stovetop settings more closely. Brewing on certain fast-heating stovetop burners such as induction may also require the user to release a portion of the generated steam from the brewer via the steam wand (17) concurrent with the brewing process. [0024] FIG.4 illustrates an embodiment brewing process with the device as shown in FIGs 1-3. As shown in FIG 4, as steam (D) develops upon heating the water within the boiler (2), heated water (Al) is forced to enter boiler funnel (4) at the lower end, which stands off approximately 3.0mm from the bottom of boiler (2). Heated water (Al) continues upward though cylindrical funnel (7) and enters pressurizing chamber (6) at an initial temperature of approximately 90° Celsius (194° Fahrenheit), where mixture with coffee media (Cl) occurs. As heated water (Al) enters pressurizing chamber (6), pressure continues to rise, which may subsequently be measured by pressure gauge assembly (8). At a predetermined amount of pressure, for example, 4 bars (58 psi), valve arm (27) of release valve assembly (9) is actuated into“open” position by either manual or automated means, allowing passage of brewed beverage (El) into duct way (10) and upward into upper brewing chamber (11) of brewing assembly (18). The release valve assembly (9) may be a one-way valve, check valve, or the like. Under sustained pressure generated by steam (D) within boiler (2) and regulated by valve arm (27) of release valve assembly (9), brewed beverage (El) moves upward into upper grounds basket (12) because the boiler (2) is in fluid communication with the brewing assembly (18) and mixes with coffee media (C2) to create brewed beverage (E2). As brewed beverage (E2) continues upward, it passes through the perforated cylindrical plate (14) to prevent passage of coffee media (C2) into collection container

(3).

[0025] Concurrent with the brewing process, steam (D) generated in boiler (2) moves upward into steam head reservoir (15) and steam duct way (16), again because they are in fluid communication with the boiler (2), where its release is manually regulated by means of steam wand assembly (17) which may be threadedly engaged with the main housing (1) and tightened to form a pressurizable seal. Following completion of the brewing process, which is determined by the manual or automated return of valve arm (27) of release valve assembly (9) to“closed” position and subsequent suspension of pressure to water mixture (A,B) in the upper brewing chamber, the manual opening of release valve (24) of steam wand assembly (17) allows the regulated passage of steam (D). The position of the valve arm and/or release valve may be controlled by a mechanism that senses pressure using a spring, or a spring and a motor (not shown), such as a solenoid with a power source. Steam (D) exiting by means of the tubular stainless steam port of the steam wand assembly (17) serves to remove accumulated pressure within the boiler (2) and pressurizing chamber (6) of main housing (1) as well as to condition milk or other liquid media for use with brewed beverage (E2).

[0026] FIG.5 illustrates an embodiment brewing process with the device as shown in FIGs 1-3. As illustrated in FIG 5, an embodiment brewing method whereby heated water only passes through coffee media once under moderate to high pressure to produce a brewed coffee beverage. One benefit of this configuration is the ability to place water of varying temperature in the lower chamber. For coffee enthusiasts, the ability to have direct control over the brewing temperature is of great importance. Placing a small amount of cold water (A2) in the

pressurizing chamber (6) will reduce the initial brewing temperature, allowing for a higher pressure brew that does not taste bitter. Placing hot or nearly boiling water in the pressurizing chamber (6) allows the brewing process to occur even faster, as the time needed to both heat the water and pressurize the chamber is greatly reduced. Other benefits include few components and less cleaning in between brewing cycles.

[0027] In the embodiment brewing process shown in FIG. 5, the boiler (2) is filled with an amount of water (Al), for example about 200ml. The flange of the cylindrical boiler funnel (4) along with the boiler gasket (5) are nested in the cylindrical recess at the bottom of the main housing (1) and the main housing (1) is threadedly engaged with the boiler (1) and tightened to form a pressurizable seal. At the discretion of the user, the pressurizing chamber (6) is filled with an amount of unheated water (A2), for example 30ml, for the purpose of regulating (by way of reducing) the water temperature achieved during the brewing process. The lower grounds basket (28) is not utilized in this example. The upper grounds basket (12) is filled with a determined amount of tightly packed, finely ground“espresso-style” coffee media (C2), for example 16 grams. The brewing assembly (18) is positioned in the upper portion of the main housing (1) and the main housing (1) is threadedly coupled to the collection container (3) and tightened to form a seal. The complete brewing assembly (19) is heated on a stovetop burner, or other appropriate heating element.

[0028] As illustrated in FIG. 6, as steam (D) develops, heated water (Al) is forced to enter the boiler funnel (4) at the lower end, which stands off approximately 3.0mm from the bottom of boiler (2). Heated water continues upward though cylindrical funnel (7) as steam pressure builds within the boiler (2), and enters pressurizing chamber (6) at an initial temperature of

approximately 90° Celsius (194° Fahrenheit), where mixture with (unheated) water (A2) occurs. As heated water (Al) continues to enter pressurizing chamber (6), pressure continues to rise, which is subsequently measured by pressure gauge assembly (8). At a predetermined amount of pressure, for example, 9 bars (130 psi), valve arm (27) of release valve assembly (9) is actuated into“open” position by either manual or automated means, allowing passage of water mixture (Al, A2) into duct way (10) and upward into upper brewing chamber (11) of brewing assembly (18). Under sustained pressure generated by steam (D) within boiler (2) and regulated by valve arm (27) of release valve assembly (9), water mixture (Al, A2) moves upward into grounds basket (12) and mixes with coffee media (C2) to create brewed beverage (E). As brewed beverage (E) continues upward, it passes through the perforated cylindrical plate (14) to prevent passage of coffee media (C2) into collection container (3).

[0029] Concurrent with the brewing process shown in FIG. 6, steam (D) generated in boiler (2) moves upward into steam head reservoir (15) and steam duct way (16) where its release is manually regulated by means of steam wand assembly (17) which is threadedly coupled to the main housing (1) and tightened to form a pressurizable seal. Following completion of the brewing process, which is determined by the manual or automated return of valve arm (27) of release valve assembly (9) to“closed” position and subsequent suspension of pressure to water mixture (Al, A2) in the upper brewing chamber, the manual opening of release valve (24) of steam wand assembly (17) allows the regulated passage of steam (D). Steam (D) exiting by means of the tubular stainless steam port of the steam wand assembly (17) serves to remove accumulated pressure within the boiler (2) and pressurizing chamber (6) of main housing (1) as well as to condition milk or other liquid media for use with brewed beverage (E).

[0030] Another embodiment of the stovetop brewing device is illustrated in FIG. 7, coupled with a brewing method whereby heated water passes through coffee media once under moderate to high pressure to produce a brewed beverage. One benefit of this embodiment is to exemplify the more common espresso-style brewing configuration whereby the brewing assembly is inverted and, assisted by both pressure and gravity, the brewed beverage is directly released into a coffee cup (37), which eliminates the need for an upper collection container.

[0031] In contrast to the embodiment depicted in FIG. 1, the embodiment in FIG. 7 includes a cylindrical boiler funnel assembly (35) which is comprised of an access port lid/cup holder (32) that is removably coupled to the main housing (1), a funnel gasket (34) residing between the lower, perforated edge of said access port lid/cup holder (32) and the upper flange of said boiler funnel (4) to form a pressurizable seal, an access port seal (33) residing between bottom inner edge of upper flange of said access port lid/cup holder (32) and said main housing (1). Boiler funnel assembly (35) provides access to boiler funnel (4) for purposes of maintenance, provides a means of routing water from boiler funnel (4) to duct way (10), and provides a secure base for the coffee cup into which the brewed beverage is delivered.

[0032] In this embodiment brewing process, the boiler (2) is filled with a determined amount of water (Al), for example about 200ml. The boiler gasket (5) is nested in the cylindrical recess at the bottom of the main housing (1) and the main housing may be threadedly coupled to the boiler (2) and tightened to form a pressurizable seal. At the discretion of the user and by means of removing access lid (36) from main housing (1), the upper brewing chamber (11) is filled with a determined amount of either heated or unheated water (A2), for example 30ml, for the purpose of either a) expediting the brewing process or b) regulating the water temperature desired during the brewing process. The upper grounds basket (12) is filled with a determined amount of tightly packed, finely ground“espresso- style” coffee media (Cl), for example 16 grams. The brewing assembly (18) may be threadedly coupled to the lower portion of the upper brewing chamber (11) of the main housing (1) and tightened to form a pressurizable seal using the cylindrical upper gasket (13), which resides between the upper brewing chamber (11) and the brewing assembly (18). The complete brewing assembly (19) is heated on a stovetop burner, or other appropriate heating element.

[0033] As illustrated in FIG. 8, steam (D) develops by heating the water (Al). The heated water (Al) is forced to enter boiler funnel (4) at the lower end, which stands off approximately 3.0mm from the bottom of boiler (2). Heated water (Al) continues upward though cylindrical funnel (7) and duct way (10) and enters upper brewing chamber (11) at an initial temperature of approximately 90° Celsius (194° Fahrenheit), where mixture with water (A2) occurs. As heated water (Al) continues to enter upper brewing chamber (11), pressure continues to rise, which may subsequently be measured by pressure gauge assembly (8). At a predetermined amount of pressure, for example, 9 bars (130 psi), valve arm (27) of release valve assembly (9) is actuated into“open” position by either manual or automated means, allowing passage of water mixture (Al, A2) into brewing assembly (18). Under sustained pressure generated by steam within boiler (2) and regulated by valve arm (27) of release valve assembly (9), water mixture (Al, A2) moves downward through perforated cylindrical plate (14) and into grounds basket (12) and mixes with coffee media (Cl) to create the brewed beverage (E). Under pressure and assisted by gravity, brewed beverage (E) continues downward through perforated cylindrical base of the upper grounds basket (12) and upper brewing chamber (11) into a coffee cup (37).

[0034] Concurrent with the brewing process shown in FIG. 8, steam (D) generated in boiler (2) moves upward into steam duct way (16) where its release is manually regulated by means of steam wand assembly (17) which is threadedly coupled, or otherwise removably coupled, to the main housing (1) and tightened to form a pressurizable seal. Following completion of the brewing process, which is determined by the manual or automated return of valve arm (27) of release valve assembly (9) to“closed” position and subsequent suspension of pressure to water in the upper brewing chamber, the manual opening of release valve (24) of steam wand assembly (17) allows the regulated passage of steam (D). Steam (D) exiting by means of the tubular stainless steam port of the steam wand assembly (17) serves to remove accumulated pressure within the boiler (2) and pressurizing chamber of main housing (1) as well as to condition milk or other liquid media for use with brewed beverage (E). [0035] In contrast to the embodiment depicted in FIG. 7, the embodiment illustrated in FIG. 9 includes a lower grounds basket (40), which may be integrated with the boiler funnel (4), that is removably coupled to the main housing (1), a boiler gasket (5) residing between the upper flange of said boiler funnel (4), and the main housing to form a pressurizable seal.

[0036] In this embodiment brewing process, the boiler (2) is filled with a determined amount of water, for example about 200ml. The boiler gasket (5) is nested in the cylindrical recess at the bottom of the main housing (1) and the main housing may be threadedly coupled (or otherwise removably coupled) to the boiler (2) and tightened to form a pressurizable seal. The upper grounds basket (12) is filled with a determined amount of tightly packed, finely ground “espresso-style” coffee media, for example 16 grams. The upper brewing assembly (11) may be threadedly, or otherwise removably, coupled to the upper portion of the main housing (1) and tightened to form a pressurizable seal using the cylindrical upper gasket (13), which resides between the upper brewing assembly (11) and the main housing (1). The complete brewing assembly (19) is heated on a stovetop burner, or other appropriate heating element. As steam and heated water develops in the boiler (2), the heated water is forced to enter boiler funnel (4) at the lower end via the increased pressure within the boiler (2). Heated water continues upward into the lower grounds basket (40) where coffee grounds are placed. Once passing through the coffee grounds, the heated water continues to travel upward via the water duct way (10) to enter the upper brewing chamber (11), because the water is still in fluid communication with the boiler (2). Under sustained pressure generated by steam within boiler (2), which may be regulated by the pressure release valve (24) that is in fluid communication to the steam in the boiler (2) via steam duct way (16), the moves downward through perforated cylindrical plate (14) and into grounds basket (12). This grounds basket (12) may contain coffee grounds or flavor additives to create a brewed beverage that is dispensed into a coffee cup (37).

[0037] What has been described above includes examples of one or more embodiments. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the aforementioned embodiments, but one of ordinary skill in the art may recognize that many further combinations and permutations of various embodiments are possible. Accordingly, the described embodiments are intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims.

Furthermore, to the extent that the term“includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term“comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
