Descriptive Report of the Invention Patent for COFFEE APPLIANCE AND REUSABLE FILTER CONTAINER FOR USE WITH DRINK PREPARATION APPLIANCE.
TECHNICAL FIELD
The present invention relates to prepared beverage apparatus and, more particularly, to a prepared beverage apparatus adapted to prepare coffee from a pre-packaged disposable container and filter combination. BACKGROUND OF THE INVENTION
Several known coffee production apparatus involve adding coffee beans in one of several ways (i.e., ground or unground) to a container that is part of a machine in which the heated water is delivered to and passes through the container. The container typically includes a filtering mechanism so that the heated water coming out of the container is in the form of prepared coffee. Certain appliances require pre-ground coffee beans added in the form of granules. Other devices are designed to accept whole coffee beans in a hopper or inlet and include mechanisms that grind the beans in a ground form and then complete the preparation process. It is sometimes preferable to keep the whole beans on hand to produce coffee so that the coffee can be ground immediately before preparation, as they are believed to produce fresher-tasting coffee drinks. Other devices require the use of pre-packaged coffee capsules or granules in a filter container sized per portion to be inserted in the device. In such cases, capsules or pre-packaged containers are limited to being filled with ground coffee. Certain prepackaged containers require placement in a separate filter mechanism on the device, while others have built-in filter mechanisms.

DETAILED DESCRIPTION OF PREFERENTIAL MODALITIES
Referring to FIGS. 1 to 7, a filter cup 10 for use with an apparatus according to the present invention includes a cup 12, a paper / cloth filter 14, a plastic screen 16 and foil cover 18. Filter 14 prevents granules of coffee and / or other sediment leave the cup 12 during preparation, but allow the passage of liquid. The cover 18 can be formed of aluminum or other material known in the art and is preferably heat sealed or otherwise releasably affixed to the top edge of the cup 10. A plurality of whole coffee beans 20 is confined in the space between the sheet cover 18 and plastic screen 16.
Although FIG. 1 showing coffee beans housed in the filter cup 10, other types of food and substances, such as tea and the like, can be used in a similar manner to that described in this document, without departing from the broader aspects of the present invention.
As further shown in FIG. 1, cup 12 has an intake
11/33 are 22 on top of it, a circumference side wall 24 and a floor 26. As best seen in FIGS. 2-7, the floor 26 has a plurality of grooves or channels 28 that direct a fluid flow to a circular depression or recess 30 that has one or more openings 32. Importantly, the recess 30 is the lowest portion of the cup 10 so that the prepared coffee is collected in the recess 30 and leaves the cup through the openings 32, as discussed below. FIG. 7 illustrates cup 10 in an assembled state and containing coffee granules 20. As shown therein, paper filter 14 is positioned on floor 26 of cup 12. Plastic screen 16 is positioned on top of paper filter 14 and protects the paper filter 14 from abrasion caused by a grinding blade and / or coffee granules. Both the paper filter 14 and the screen 16 are circular and sized to be received by the side wall in circumference 24 of the cup at the bottom of the cup. As best shown in FIG. 7, the screen 16 can be resilient and resistant to folding so that the screen 16 provides a flat surface in the cup 12 on top of which the coffee bean 20 can settle. Relevantly, the screen 16 prevents the coffee beans 20 from falling to the floor 26 of the cup 12 (which may be out of reach of a grinding blade) to facilitate optimal grinding by the grinding blade, as discussed in detail below . As discussed above, the leaf cover 18 seals the filter 14, the screen 16 and the coffee beans 20 inside the cup 12.
Cup 10 can be stored and transported in a separate package or packaging for additional freshness and protection and openings 32 on floor 26 can be covered with, for example, an adhesive label (not shown). In the preferred embodiment, the filter cup 10 is a disposable component, single portion, pre-packaged. Thus, it is sealed by the leaf cover 18 in an airtight manner to preserve freshness and flavor and to protect coffee beans 20 from moisture and contamination. As discussed above, the filter cup 10 can be sealed by the foil cover 18 and an adhesive label or can be packaged in a package with or without the adhesive label. In an alter mode
12/33 native, it is contemplated that the filter cup 10 can be, instead, a reusable cup that is refilled for each use. In one embodiment, the floor of the cup 26 can be formed without openings 32. In this embodiment, the floor of the cup 26 can be pierced by a needle by inserting it into a coffee machine to provide an outlet for the flow of prepared coffee.
Referring now to FIG. 8, an alternative construction of a filter cup 50 is shown. As shown therein, the cup 50 is substantially similar in shape and construction to the cup 10, however, a metal mesh filter 52 can be used in place of the paper / cloth filter 14 and the protective plastic screen 16. In this In this embodiment, the metal mesh filter 52 is thin enough so that it prevents the coffee granules from leaving the cup 10 and also provides a level of abrasion resistance. Although it has been revealed that the filter 34 can be formed of a metal mesh, other materials substantially resistant to abrasion of the grinding blade and / or coffee granules can also be used without departing from the broader aspects of the present invention.
Referring to FIGS. 9 to 24, an apparatus 100 according to an embodiment of the present invention is shown. The apparatus 100 is intended to be used in combination with the filter cup 10, disclosed above, in order to prepare a coffee or other beverage. As shown therein, the apparatus 100 is generally rectangular in shape and comprises a base 102 and a drip tray housing 104 which slidably receives a drip tray 106 which has a top surface with slits or slots 108. A surface 108 of tray 106 is adapted to have a container, such as a coffee mug 109, placed on it to receive coffee prepared as it is produced by and emitted from apparatus 100. As will be readily apparent, the slotted surface 108 allows liquid that can be spilled from cup 109 or that can come out of cup 109 during operation to pass through surface 108 and to be collected in drip tray 106, for easy cleaning.
An accommodation 110 is located above and supported by the ba
13/33 if 102 and a sliding filter cup / tray 112 is slidable to hold and position the filter cup 10 during use. A handle 114 is pivotably mounted to housing 110 for operation, as described below. As further shown in FIGS. 9 and 10, a water reservoir 116 is attached to, supported by and otherwise forms part of housing 17. In one embodiment, water reservoir 116 can be removably or permanently mounted to housing 110. Housing 110 also includes a control panel 118 to control operational features of the device, as discussed below. As best shown in FIG. 9, the base 102 includes a recess on one side for slidably receiving a waste tank 120 for receiving water from a cleaning operation of the apparatus 100 (described below) and discarded filter cups 10 after use. In an alternative embodiment, tray 112 can be pivotally received by housing 110 and movable between a first position where the housing / tray 112 is received inside the housing and a second position where tray 112 is pivoted away from the housing and towards a user to facilitate the installation of a filter cup 10. In one embodiment, tray 112 is removable from housing 110 for cleaning.
The operation of the apparatus 100 will now be described with specific reference to FIGS. 17 to 24. First, the water tank 116 is filled with water. A user then selects the desired coffee settings from the control panel 118. The settings can include selectable options such as coffee concentration and portion size, timer setting, automatic brewing, etc. The handle 114 is then moved upward in the direction of arrow A, as shown in FIG. 17, in order to unlock tray 112 from its seated and retained position inside housing 110. Tray 112 slides out of apparatus 100 in the direction of arrow B to the position shown in FIG. 18, under the force of a spring 154. In that position, the tray 112 is ready for a filter cup 10 to be placed on the receiving support 124 in the tray 112.
After cup 10 is inserted into tray 112, tray 112 is
14/33 now ready to be pushed back into apparatus 100 in the direction of arrow C, as shown in FIG. 19. In particular, tray 112 is manually pushed back into apparatus 100 so that it is received by housing 110 in the locked position, as shown in FIG. 20. Handle 114 is then lowered in the direction of arrow D in order to automatically start the grinding and preparation processes.
Referring to FIG. 21, as mentioned above, the grinding process starts automatically after the handle 114 is lowered. In the process, the coffee beans 20 in the filter cup 10 are ground by a grinding blade 126 which is received inside the cup 10 so that the beans 20 are transformed into coffee granules 128. After the grinding is completed, water heated water is delivered to cup 10 from a water outlet described below. As represented by the arrow 130 in FIG. 22, coffee is emitted from the bottom of tray 112, which has an inlet to enable such emission, in the coffee mug 109 positioned under tray 112.
After the preparation process is completed, handle 114 is raised from the position shown in FIG. 23 in the direction of arrow E to the position shown in FIG. 24. Again, the movement of the handle 114 to its upper position unlocks the tray 112 so that it slides out of the housing 110 of the apparatus 100, allowing the user to manually remove the used filter cup 10 from the tray 112. The cup 110 can then be discarded in the waste tank 120. The full mug 109 of coffee can be removed from the drip tray 106 before or after this step.
In one embodiment, although tray 112 is in the out position, as shown in FIG. 24, a blade cleaning operation starts automatically. In the blade cleaning operation, water is emitted from the water outlet 132. Due to the fact that the cup 10 has been removed, the blade is surrounded by space, thus allowing the flowing water to clean it. In one embodiment, the blade can rotate during application of water to facilitate cleaning. Since tray 112 is in the out position, the
15/33 water will not be drained from the bottom of cup 10 and tray 112, as it does in the preparation mode. Instead, water is diverted due to the fact that it falls at the rear end 134 of tray 112 in a collection basin 136, as shown in FIG. 59. The water comes out of the collection bowl 136 of tray 112 through a discharge tube 138 and falls into the discharge tank 120.
In an alternative embodiment, a glass containing a cleaning liquid, such as water, can be used to clean the blade 166 either periodically or after each use. In this embodiment, a cleaning cup is inserted into the receptacle 124 and the apparatus 100 is operated by pulling the handle 114 downwards. The apparatus 100 can then carry out a normal preparation cycle. Alternatively, a button on the control panel 118 can be pressed to perform a cleaning cycle. The cleaning cycle can be specifically configured, for example, water temperature, run time, blade rotation speed to optimize cleaning and sterilization. In alternative embodiments, the cleaning cup may contain a cleaning solution or fluid paste of cleaning ingredients. The cleaning ingredients can be liquid or dry and can be in the form of granules, powder, etc.
In another mode, a cleaning operation can include running a preparation cycle without actually inserting a filter cup 10. In this mode, handle 114 can be moved down to start the cycle so that heated water is passed over the blade stationary or swivel 166 to clean the blade. Alternatively, a button on the control panel 118 can be pressed to start the cleaning cycle.
FIGS. 62 and 63 illustrate tray 112 and collection bowl 136. FIG. 64 illustrates the bottom view of tray 112 and shows the inlets 32 of the cup 10 as seen through an inlet 140 on the bottom of the tray 112 that allows the prepared coffee to flow out.
FIG. 25A schematically illustrates how ground coffee 128, which is ground from whole coffee beans 20 in a procedure described below, is infused with heated water to produce coffee. Ground coffee
16/33 of the 128 is located in the cup 10 and heated water is introduced from above through a water outlet 132 as indicated by the arrow 142. The heated water flows through the ground coffee 128 in the cup 10 and exits the openings 32 at the bottom of the cup 10 as shown by arrow 144.
FIGS. 26 and 27 illustrate certain internal components of the apparatus 100. As shown therein, the water reservoir 116 is filled with water. Tray 112 is removed to allow placement of a cup 10 on a receiving support 124 in tray 112, as shown in FIGS. 18 and 19. Tray 112 is then pushed back into the apparatus to the position shown in FIG. 20. Handle 113 is then moved downward, as shown in FIGS. 21 and 22. Such movement of the handle 114 causes the cup 10 to be raised for grinding the coffee beans 20 in the cup 10, as described below. Apparatus 100 includes a heater 146 and a pump 148 for heating water in reservoir 116 and directing it through a supply line to perform a preparation operation as described with reference to FIG. 25A. As shown in FIGS. 26-29, a grinder motor 150 is positioned in the housing 110 of the apparatus 100 to perform the grinding of the coffee beans 20 in a manner described below. A hot water pipe 152 carries the heated water from the heater 146 to the water outlet 132 located above the tray 112.
As best shown in FIGS. 27 and 29, the lifting mechanism 156 is activated by the handle 114 in order to cause the cup 10 to move between a lowered position and an elevated position. The mechanism 156 includes a connecting arm 158, a pin 160 operatively attached to the receiving support 124 of tray 112 and associated slot 162 and a plate 164 on which slot 162 is located. In operation, by moving handle 114 downward, pin 160 follows the path of groove 162 and causes cup 10 and receiving support 124 to be raised on the grinding blade. Guide frames 161 are received in boreholes 163 of the receiving support to ensure proper orientation and alignment of cup 10 with the grinding blade. O
17/33 lowering of cup 10 follows the reverse process.
Referring to FIG. 30, apparatus 100 includes a grinding blade 166 attached to and driven by a rotating output shaft 168 associated with the grinding motor 150. When the handle 112 is moved to the lowest position, as shown in FIG. 28, cup 10 is raised so that blade 166 engages and pierces through sheet cover 18 and enters cup 10 and contacts coffee beans 20. Cup loading / lifting mechanism 156, which is activated by the handle 114, moves the cup 10 between that raised position for grinding and a lowered position. The spring 154 is a user-assisted spring which induces the tray 112 out of the housing 110 when the handle 114 is then raised in order to insert a cup 10.
As shown in FIG. 31, the movement of the handle 114 to the elevated position unlocks the tray 112 so that it slides out under the force of the spring 154 in cooperation with a plate 165 (which serves as an anchoring object from which the spring gradually releases ) to allow a cup 10 to be positioned on the receiving support 124 of tray 112. A user then places a cup 10 on tray 112 as shown in FIG. 32. Tray 112 must be manually pushed back to the closed position as shown in FIG. 33 until it locks into place by the tray lock 170 shown in FIG. 34.
FIGS. 35 to 37 illustrate the drilling and milling sequence in accordance with the present invention. As shown in FIG. 35, the filter cup 10 is raised towards the blade 166, in the direction of the arrow F when the handle 114 is lowered. FIG. 36 illustrates the position of the cup 10 when it is completely raised. In that position, a sealing ring 172, such as an O-ring, engages a top edge of the cup 10 so that, when the preparation process takes place, the cup 10 can be pressurized. FIG. 37 illustrates the lowered position of cup 10 after grinding and preparation has taken place and handle 114 is raised. Relevantly, the sealing ring 172 seals the top of the cup 10 so that the
18/33 cup can be pressurized. In the preferred embodiment, the cup is pressurized in excess of 200 kilopascals (2 bar) during preparation, although other pressures can be used without departing from the broader aspects of the present invention.
Various views of the grinding blade 166 for grinding whole coffee beans are shown in FIGS. 38 to 43. As shown therein, blade 166 has a V-shaped configuration. Relevantly, blade 166 has insert cut edges 174 so that sheet cover 18 of cup 10 can be perforated when the cup 10 is moved by upward movement of handle 114. The top of the blade also includes extract cutting edges 176 for cutting through the sheet cover 18 when cup 10 is lowered away from the blade subsequent to preparation by upward movement of handle 114. Each leg of the V is also formed with an opposite recess 178 and raised crest 180 to facilitate the grinding of coffee beans 20, as described below. The blade 166 also includes a collar 182 for connection to the output shaft 168 of the grinding motor 150. In such an embodiment, the blade 166 can be removable for replacement and / or more thorough cleaning. In an alternative embodiment, the blade 166 is integrally formed or otherwise fixedly attached to the output shaft 168 of the motor 150. As will be easily perceived, the thin profile of the blade 166 cuts a groove with a minimum width in the leaf cover 18 to prevent the coffee granules 128 from being thrown out of cup 10 during grinding. In addition, the shape and configuration of blade 166 facilitates cleaning.
FIG. 44 illustrates cup 10 being raised toward blade 166 and FIG. 45 illustrates the blade 166, through the insert cutting edges 174, perforating the leaf cover 18 of the cup 10. In both FIGS. 44 and 45, coffee beans 20 in cup 10 are not yet ground. After grinding, beans 20 were transformed into ground coffee 128. Preparation takes place, as described above, and cup 10 is then lowered as shown in FIGS. 46 and 47 so that the extract cutting edges 176 of the blade 166 again pierce the foil cover 18, if necessary,
19/33 to facilitate removal of cup 10 from blade 166.
Referring now to FIGS. 48 to 50, the actual grinding process is illustrated. Upon actuation of the grinding motor 150, the grinding blade 166 rotates at a frequency high enough to grind the coffee beans 20 in the filter cup 20 to transform the coffee beans 20 into whole beans, as shown in FIG. 48, in granules, as shown in FIG. 60. In particular, blade 166 is rotated in one direction (see FIG. 49) which causes crest 180 on blade 166 to strike / impact coffee beans 20 to cause them to divide. Over time, numerous impacts of the blade itself, and more significantly, through the 180 ridges, gradually reduce the size of the coffee beans to fine enough granules for preparation. In one embodiment, blade 166 may continue to rotate at a predetermined frequency during the preparation process, that is, during the time during which hot water is passed through cup 12. The frequency of rotation during preparation may be the same that, or different from, the frequency used to grind coffee beans 20. In other embodiments, blade 166 can be used to stir the drinkable liquid ingredients during preparation, in order to facilitate the dissolution of the drinkable liquid ingredients in the water passing through cup 10 (for example, when using iced tea drinkable ingredients instead of whole coffee beans). As will be readily apparent, stirring the drinkable liquid / coffee beans ingredients inside the cup 10 during preparation can produce a drink that tastes better. In particular, stirring during preparation can improve the contact between the coffee granules 128 and the hot water, which can improve the quality and / or concentration of the coffee.
In an alternative embodiment, the filter cup 10 can be retracted from the grinding blade 166 before dispensing heated water to the cup 10. As will be easily understood, this ensures that the grinding blade 166 only touches the coffee when it is dry. (that is, when it grinds the coffee beans 20 before preparation). Thus, granulated coffee is not as susceptible to blows from the blade 166 when
20/33 the same would be the case if blade 166 and ground coffee 128 were present together in a humid environment and, therefore, the blade is kept substantially free of coffee granules without having to clean the blade.
FIGS. 52 to 57 illustrate an alternative configuration for a grinding blade 184 that can be used with the apparatus 100. As shown therein, the blade has a V-shaped configuration and has a perforation edge 186 to perforate the foil cover 18 of cup 10. Blade 184 also has two horizontally extending flanges 188, 190 to facilitate grinding of coffee beans 20 and two upward edges 192, 194 to again cut through sheet 18 when cup 10 is lowered away from the blade 184. Like blade 166 of the preferred embodiment, blade 184 can be releasably attached to the output shaft 168 of the grinding motor 150, or it can be integrally formed or otherwise permanently attached to it.
The water path used in the process of the present invention is illustrated in FIG. 58. Firstly, reservoir 116 is filled with water. In one embodiment, reservoir 116 can be releasably received in housing 110 so that a user can remove reservoir 116 to fill it with water and then place it in housing 110. As will be readily apparent, such a configuration can be easier than bringing a water source to the reservoir itself. Reservoir 116 may have a removable cap 194 as shown in FIG. 60 to facilitate filling with water. A water outlet 196, best shown in FIGS. 17 to 24, allows water to flow from reservoir 116 under the force of gravity. Outlet 196 can be equipped with a valve 198 of a type commonly known to those skilled in the art, in which the valve can be electronically activated and controlled by means of a conventional controller from an open position to a closed position and vice versa. During preparation, water leaves reservoir 116 through outlet 196 and travels through a first tube 200 until it reaches pump 148. Pump 148 pumps water through heater 146 in order to heat water to a predetermined temperature desired.
21/33
The water passes from the heater 146 through the hot water supply pipe 152 to the water outlet 132.
In one embodiment, at the end of the preparation process, the water flow will be stopped before the heater so that the steam is generated to push or blow the excess liquid remaining in the cup 10. As will be easily perceived, this jet of steam guarantees that the last drops of coffee do not remain in the cup 10 and prevents dripping.
As shown in FIG. 25B, in one embodiment, the water outlet 132 is a watering can in the form of an annular tube or ring 208 that has a plurality of openings 210 formed therein to distribute heated water. The heated water emitted from the openings 210 of the sprinkler 132 is used both to prepare the coffee and to clean the blade 166 in the cleaning operation. During preparation, the heated water that leaves the water outlet / watering can 132 enters cup 10, which at this point in the process contains ground coffee 128. Water, now prepared coffee, leaves cup 10 through openings 32 on floor 26 of the cup 10. As it exits the cup through the openings32, it travels down through an outlet duct in tray 112 before emission through the outlet of tray 202. In one embodiment, the tray may include a smoothing member flow 204 directly below the openings 32 of the filter cup 10. The flow smoothing member delays the direct flow of prepared coffee in the coffee mug 109 so that the prepared coffee does not spill or splash on the user or make dirt. After leaving exit 202, the water, which has now become prepared coffee, falls into coffee mug 109. The volume of liquid selected, corresponding to the portion size, is pre-selected using controls 118 and pump 148 and the water outlet 196 are likewise controlled to allow flow of only the selected quantity before interrupting the flow.
FIGS. 65 to 67 illustrate an alternative configuration of drip tray 106 in accordance with another embodiment of the present invention. As shown therein, the drip tray is movable between a first position, as shown in FIG. 66, where
22/33 tray 106 is positioned below the prepared coffee outlet 202 and a second position, as shown in FIG. 7, where the drip tray 106 is housed within the base 102 of the apparatus 100. With the drip tray 106 in the position shown in FIG. 67, taller cups / mugs 206 can be accommodated.
FIG. 68 illustrates a coffee apparatus 300 having an alternative configuration in accordance with an embodiment of the present invention. As shown therein, instead of the bowl 10 being installed vertically and the grinding blade 166, preparation sprinkler 132 and motor 150 being in a vertical position above the bowl 10, these elements are oriented horizontally. In particular, as shown therein, the filter cup 10 is installed in a horizontal orientation inside the housing 110. Additionally, the grinding motor 150, watering can 132 and blade 166 are positioned next to the cup 10 in a horizontal position. In this embodiment, the apparatus 300 includes a conduit 302 in communication with the bottom of the cup 10 so that the prepared coffee leaves the cup and is directed through the conduit 302 to the outlet 202 for distribution to a user's cup 109.
FIGS. 69 and 70 illustrate a coffee machine 400 according to another embodiment of the present invention. The coffee apparatus 400 is similar in configuration to that of the apparatus 100 disclosed above, with some notable differences. As shown therein, instead of the motor 150, the blade 166 and the watering can 132 are stationary and the bowl 10 is raised in engagement with the blade 166, in this embodiment, the preparation watering can 132, the motor 150 and the blade 166 are configured to move towards and away from a stationary cup 10. FIG. 69 illustrates a first position of motor 150, blade 166 and preparation head 132 above the stationary filter bowl 10. Motor 150, blade 166 and preparation head 132 are movable in the vertical direction to a second position, shown in FIG. 70, in which the blade is arranged inside the cup 10. The vertical movement of the motor 150, blade 166 and watering can 132 can be carried out using mechanical action or electric actuators.
23/33
The coffee machine 400 according to this modality can be characterized as having an active preparation assembly (engine 150, grinding blade 166 and watering can 132) and a passive filter cup 10, as opposed to an active filter cup 10 and passive preparation assembly.
Although the preferred mode includes grinding and preparing coffee from whole coffee beans, the present invention is not intended to be limited in this regard. In particular, it is envisaged that the apparatus and method of the present invention are not limited to cups containing whole grain coffee, per se, and the invention can be used with cups containing ground coffee, partially ground coffee, tea leaves, ground tea or drinkable liquid mix ingredients. In addition, the apparatus according to the modalities of the present invention can produce / prepare beverages from any ingredients contained within the filter cup and is not limited to preparing coffee from whole coffee beans.
FIGS. 71 and 72 illustrate a double portion coffee machine 500 in accordance with another embodiment of the present invention. The double portion coffee apparatus 500 is substantially similar to, and operates in substantially the same manner as, the coffee apparatus 100 disclosed above. As shown in FIGS. 71 and 72, the coffee apparatus 500 includes a housing 502, a base 504 and the filter cup tray 506 slidably received in the housing 502 and sized to receive a filter cup, such as filter cup 10, in the near future, containing at least one drinkable liquid ingredient. The drinkable liquid ingredient can be whole coffee beans. A grinding motor 508 is positioned in the housing 502 on the filter cup tray 506 and includes a blade assembly 510 for grinding the coffee beans, in the manner previously disclosed herein. In particular, the tray 506 can be moved towards the blade assembly 510 so that a cover of the filter cup is perforated by the blade 510 and the blade 510 enters the cup. Alternatively, motor 508 and blade 510 can be moved towards the cup so that a cover is perforated by blade 510
24/33 and blade 510 enter the cup. In any case, once the blade 510 is positioned inside the cup, the engine 508 is activated, causing the blade 510 to rotate at a predetermined frequency, thus grinding the whole coffee beans or otherwise mixing the ingredients of drinkable liquid inside the glass.
As further shown in FIGS. 71 and 72, the coffee apparatus 500 includes a water reservoir 512, a pump 514 and a heater / boiler 516. After the coffee beans are ground into the cup, water is pumped from the water reservoir 512 through the heater 516, which heats the water to a predetermined temperature. The water then continues from the heater 516, through a supply line 518 and up to a watering can 520 positioned above the filter cup and tray 506 from which it is passed through the filter cup to produce prepared coffee.
Relevantly, as shown therein, the filter cup tray 506 includes two outlet openings at the bottom thereof, a first outlet opening 522 and a second outlet opening 524 spaced from the first outlet opening 522. A FIG. 71 illustrates the double portion coffee maker 500 in a single portion mode. As shown therein, a single coffee cup 526 is placed on the base 504 directly below the two outlet openings 522, 524 on tray 506. A user then selects or presses a single portion button on a control panel (not shown) . The coffee apparatus 500 then prepares a predetermined individual serving volume of coffee and dispenses the prepared coffee from the two outlet openings 522, 524.
FIG. 72 illustrates the double portion coffee maker 500 in a double portion mode. As shown therein, two coffee cups 526 are placed on the base 504 so that one cup 526 is below the first outlet opening 522 and the other cup 526 is below the second outlet opening 524. A user then presses a button. two portions on the control panel and the device 500 then prepares a volume of two portions of coffee. Coffee is also dispensed out of the first and second spouts 522, 524 to fill the two cups of coffee
25/33
526. As will be readily apparent, the double portion coffee maker 500 is capable of delivering two cups of coffee simultaneously. This ensures that the coffee in each cup is at substantially the same temperature and is ready at the same time. This is possible due to the fact that the two outlet openings 522, 524 are positioned substantially the same distance from the openings 32 of the filter cup 10 and the openings 522, 524 have substantially similar dimensions.
Referring now to FIGS. 73 and 74, a beverage apparatus 600 according to another embodiment of the present invention is shown. The coffee apparatus 600 includes a housing 602, a base 604 and the filter cup tray 606 received slidably into the housing 602 and sized to receive a filter cup, such as filter cup 10, containing at least one drinkable liquid ingredient. The drinkable liquid ingredient can be whole coffee beans. A grinding motor 608 is positioned in the housing 602 on the filter cup tray 606 and includes a blade assembly 610 for grinding the coffee beans, as previously disclosed in this document. In particular, the tray 606 can be moved towards the blade 610 assembly so that a cover of the filter cup is perforated by the blade 610 and the blade 610 enters the cup. Alternatively, motor 608 and blade 610 can be moved towards the cup so that a cover is perforated by blade 610 and blade 610 enters the cup. In any case, once the blade 610 is positioned inside the cup, the motor 608 is activated, causing the blade 610 to rotate at a predetermined frequency, thus grinding the whole coffee beans or otherwise mixing the ingredients of drinkable liquid inside the glass.
As further shown in FIGS. 73 and 74, the beverage apparatus 600 includes a water reservoir 612, a pump 614 and a heater / boiler 616. An emission from heater 616 is in fluid communication with a water path selector 618 which is configured to selectively deliver water to a preparation supply line 620 or a hot water pipe 622 depending on a button / mode selected by
26/33 a user on a control panel (not shown). The preparation supply line 620 is in fluid communication with a watering can 624 positioned above the filter cup tray 606 and configured to dispense hot water in the filter cup. The 618 water path selector can be a valve that has a single inlet and two emissions.
FIG. 73 illustrates the beverage apparatus 600 in a brew mode, as selected by a user by pressing a brew mode button on a control panel (not shown). As shown therein, a filter cup is received in the filter cup tray 606. The filter cup 10 is inserted into the housing directly under the grinding blade 610 and the engine 608. After grinding the interior coffee beans inside from the filter cup 10, water is pumped from the water reservoir 612 through the heater 616, which heats the water to a predetermined temperature. The water then continues from the heater 616 to the water path selector 618, where it is directed to the preparation supply line 620. The hot water is then distributed through the watering can 624 through the filter cup 10 to prepare the coffee. The prepared coffee then leaves the filter cup 10 through the openings in the bottom of the same and finally leaves the filter cup tray 606 through a preparation outlet 626 at the bottom thereof. The prepared coffee is then collected in a coffee cup 628 positioned under the preparation outlet 626 in the base device 604.
FIG. 74 illustrates the beverage apparatus 600 in a hot water dispensing mode. In operation, a user selects an option of only hot water from the control panel on the device 600 and places a cup 628 directly under a hot water outlet 630. The water is then pumped from the water reservoir 612, through the heater 616, which heats the water to a predetermined temperature. The heated water then continues from heater 616 to the water path selector 618, where it is then directed to the hot water pipe 622 and directly out of the hot water outlet 630.
As will be easily perceived, the drink apparatus 600
27/33 allows a user to either prepare a cup of coffee or dispense hot water only. Relevantly, these two functions are physically separated using the water path selector 618. This physical separation ensures that the hot water dispenser is clean and is not contaminated by coffee. In particular, this configuration ensures that coffee is not dispensed in a user cup during hot water only mode, or that hot water has an underlying coffee flavor or odor contamination.
Another embodiment of the present invention relates to a water heating system and a temperature control method for a beverage apparatus such as a coffee maker. As shown in FIG. 75, a beverage apparatus 700 that has a heating and water temperature control system includes a water reservoir 702, a pump 704 and a boiler / heater 706. As with the modalities shown above, pump 704 pumps water from the water tank 702, through heater 706 (where the water is heated to a predetermined temperature) and to a watering can 708 through a supply pipe 710. Watering can 708 is positioned on a filter cup 10 received in housing 712 of the appliance and dispensing the heated water in the cup 10 to produce prepared coffee (or other drinkable liquid) for distribution to the cup of a user 714 positioned on a base 716 of the apparatus 700.
As shown therein, the apparatus 700 includes a water inlet sensor 718 positioned in the conduit that connects the water reservoir 702 to the heater 706. The water inlet sensor 718 is electrically connected to a controller inside the apparatus 700 ( and which has a printed circuit board 720) and measures the water temperature before entering the heater 706. The water inlet sensor 718 transmits the detected temperature to the controller. Apparatus 700 also includes a water outlet sensor 722 positioned downstream of heater 706 which measures the temperature of the water leaving heater 706. The outlet sensor 722 is also electrically connected to the controller to transmit the detected temperature. The 706 heater itself is also configured
28/33 with a heater sensor 724 to measure the temperature of heater 706. As with output sensor 722 and inlet sensor 718, heater sensor 724 is electrically connected to the controller to transmit the detected temperature to it. As shown therein, the apparatus 700 also includes a flow meter 726 positioned adjacent to the outlet of the water reservoir 702 that measures the flow of water leaving the reservoir 702. Particularly, in one embodiment, the flow meter 726 measures the rate flow of water that leaves reservoir 702 and transmits this information to the controller.
Referring to FIGS. 76 to 79, detailed views of the heater / boiler 706 are shown. As shown therein, heater 706 includes an extruded aluminum housing 728 that surrounds a generally cylindrical water channel 730. Two heaters, such as Bundy heaters 732, are positioned inside the extruded aluminum housing 728 adjacent to the heating channel. water 730. In operation, heaters 732 heat the extruded aluminum housing 728 and the aluminum walls of the water channel 730 to thereby heat the water that passes through it. As will be readily apparent, the construction of the extruded aluminum heater / boiler 706 results in a very light heater. In this way, the heater 706 is able to heat up to the desired temperatures very quickly, thus freeing itself from the need, in certain cases, for preheating before preparation.
FIGS. 80 to 82 illustrate the water heating process used during the preparation cycle. As shown in FIG. 80, the first step in the water heating process is preheating. When the user turns on the main power to the device 700, the heater in the boiler 706 will also turn on. The heater sensor 724 monitors the temperature of the boiler 706 and, together with the controller, provides temperature regulation (that is, it turns the heater off and / or decreases the energy for it) when the desired temperature has been reached. As illustrated in FIG. 80, during preheating, only one of the 732 heaters is activated to reach the desired boiler preheating temperature
29/33 while avoiding substantial excess temperature. In other embodiments, lower energy (for example, electronically reduced energy) can be used in the preheating step to achieve the desired preheating temperature. In one embodiment, preheating can be an optional step depending on the efficiency of the 706 boiler in heating the water that passes through it. As will be readily apparent, preheating ensures that the first jet of water in the filter cup 10 has reached the desired preparation temperature. Preheating may be necessary in cases where the device 700 has not been used for some time so that the boiler 706 has cooled down completely.
Turning now to FIG. 81, a preparation step is illustrated. As shown therein, water is pumped from reservoir 702 to filter bowl 10. Relevantly, when pump 704 is activated by the controller, both heaters 732 in boiler 706 automatically turn on and heat up. During operation, the water that passes through water channel 730 of boiler 706 will thus heat up instantly. The water inlet and outlet sensors 718, 722 monitor the water temperature just before entering the boiler 706 and just after leaving the boiler 706 and transmit the detected temperatures to the controller for analysis and system control. For example, when the temperature of water leaving boiler 706 is lower than desired, as detected by outlet sensor 722, the controller will encourage pump 704 to decrease the flow rate to give the water more time to heat and reach the desired temperature as it passes through the boiler 706. As mentioned above, the flow rate is monitored by the flow meter 726. Relevantly, the controller and the PCB 720 continuously monitor the flow rate and water and the temperatures of water at various points along its path and adjust the flow rate and / or heater energy to maintain an ideal water preparation temperature throughout the preparation cycle. In view of the above, the system of the present invention correlates the flow rate of the water with an energy level delivered by the heaters 732 in order to heat the water to a desired temperature throughout the cycle of
30/33 preparation.
FIG. 82 illustrates a cleaning step, after preparation, in which any water remaining in the lines is eliminated. As shown therein, near or at the end of the preparation step, the pump will stop before heaters 732 are turned off. This results in the excess water remaining in the boiler being converted to steam. The steam 734 then travels through the supply line 710 and forces out the hot water in the preparation cavity (line 710, watering can, etc.) and the filter cup 10. As will be easily perceived, this ensures that substantially all of the coffee in cup 10 come out without substantial drip. In addition, this also ensures that cup 10 is dry and does not drip when it is removed for disposal.
Referring to FIGS. 83 to 88, an alternative filter cup 800 for use with an apparatus according to the present invention includes a cup body 802, a filter 804, a protective screen 806 and a cover 808. Filter 804 is preferably a paper filter or a filter formed from another material used in known coffee producers and is positioned adjacent to the bottom of the cup body 802. The filter 804 prevents granules of coffee and / or other sediment from leaving the cup 800 during preparation, but allows passage of liquid. Protective fabric 806 is preferably formed of plastic or other abrasion resistant material and is positioned on top of filter 804 inside cup 800. Relevantly, fabric 806 protects paper filter 14 from abrasion caused by the grinding blade and / or coffee granules. As shown therein, both the paper filter 804 and the screen 806 are circular and sized to be received by the side wall in circumference of the cup at the bottom of the cup.
The cover 808 is preferably a sheet, although it may be formed of aluminum or other material known in the art, and is preferably heat sealed or otherwise releasably affixed to the top edge of the cup 10. A plurality of whole coffee beans 810 is confined in the space between the cover 808 and the protective screen 806. Although
31/33 to FIG. 83 showing the coffee beans housed in the filter cup 800, other types of foods and substances, such as tea and the like, can be used in a manner similar to that described in this document, without departing from the broader aspects of the present invention. Notably, cup 800 is completely sealed so that it provides a completely airtight container for 810 coffee beans. As will be easily understood, this helps to maintain the freshness of 810 coffee beans before use.
A coffee machine 850 for use with airtight filter cups 800 is shown in FIG. 89. The coffee apparatus 850 is substantially similar to, and operates in substantially the same manner as, the coffee apparatus 100 disclosed above. As shown therein, the coffee machine 850 includes a housing 852, a base 854 and the filter cup tray 856 received slidably into the housing 852 and sized to receive a filter cup 800 next. A grinding motor 858 is positioned in housing 852 on the filter cup tray 856 and includes a blade assembly 860 for grinding coffee beans, as previously disclosed in this document. In particular, the tray 856 can be moved towards the blade assembly 860 so that the cover 808 of the filter cup is perforated by the blade 860 and the blade 860 enters the cup 800. Alternatively, the motor 858 and the blade 860 can be moved towards cup 800 so that cover 808 is perforated by blade 860 and blade 860 enters cup 800. In any case, once blade 860 is positioned inside cup 800, motor 858 is actuated, causing the blade 860 to rotate at a predetermined frequency, thus grinding the whole coffee beans 810 or otherwise mixing the drinkable liquid ingredients inside the cup 800.
As shown here, the coffee machine 850 includes a water tank 862, a pump 864 and a heater / boiler 866. After the coffee beans 810 are ground inside the cup 800, the water is pumped from the water tank 862 through heater 866, which heats the water to a predetermined temperature. THE
32/33 water then continues from the heater 866, through a supply duct 868 and even a watering can 870 positioned above the filter cup 899 and the tray 856 from which it is passed through the filter cup 800 to produce prepared coffee.
Relevantly, as best shown in FIGS. 90 and 91, the filter cup tray 856 includes a hollow needle 872 that extends above the floor thereof. This needle / tube is needed to drill a hole in the bottom of the airtight filter cup 800 when it is inserted into the filter cup tray 856 and serves as an outlet for coffee after preparation. In operation, a user selects a filter cup 800 that contains his choice of coffee beans and presses cup 800 into the recess in the filter cup tray 850 so that the hollow needle pierces the bottom of the filter cup 800. The tray 850 can then be inserted into the coffee maker 852 to continue the brewing process as described above.
Referring now to FIGS. 92-96, a 900 reusable filter cup for use with the coffee and beverage apparatus disclosed above is shown. The reusable filter cup 900 includes a cup body 902, a filter 904, a protective screen 906 and a cover 908. The filter 904 is preferably a permanent filter that is constructed of a material that is durable and capable of repeated use. As with the filter cups disclosed above, filter 904 prevents granules of coffee and / or other sediment from leaving cup 900 during preparation, but allows liquid to pass through. Protective fabric 906 is preferably formed of plastic or other abrasion resistant material and is positioned on top of filter 904 inside cup 900. Relevantly, fabric 806 protects paper filter 14 from abrasion caused by the grinding blade and / or coffee granules. The protective screen 906 can be removable.
The cover 908 is dimensioned to be close and firmly received in the cup body 902 and is preferably formed of rubber or other durable, deformable and malleable material. The 908 cover is removable to allow a user to fill the 900 cup with 910 coffee beans.
33/33
Relevantly, cover 908 includes a plurality of slits 912 extending from a central opening 914. Slits 912 allow the grinding blade to be inserted through cover 908 without destroying cover 908 so that the container, including cover , can be reused. In addition, the cover configuration helps to retain the coffee granules in cup 900 during grinding. In addition, such a cup construction also facilitates cleaning of cup 900. The floor of cup 900 is substantially the same as that of filter cup 100 and includes a plurality of openings.
FIGS. 93 to 96 illustrate the use of the reusable filter cup 900. As shown in them, with cover 908 removed, selected coffee beans 910 are inserted into cup 900. As shown in 94 and 95, cover 908 is placed on the body cup 902 to confine coffee beans 910 therein. The cup 900 can then be inserted into an apparatus, such as apparatus 100, in the manner described earlier in this document and the preparation process started. As shown in FIG. 96, a grinding blade 916 can then be inserted through slots 912 so that the axis of the grinding blade is received at opening 914 in cover 908.
Although the invention has been shown and described in relation to its detailed modalities, it will be understood by those skilled in the art that various changes can be made and equivalents can be replaced by elements of the same without departing from the scope of the invention. In addition, modifications can be made to adapt a particular situation or material to the teachings of the invention without departing from its essential scope. Therefore, it is intended that the invention is not limited to the particular modalities disclosed in the detailed description above, but that the invention includes all modalities that are within the scope of this disclosure.
