Description

BEVERAGE BREWING APPARATUS
BACKGROUND
FIELD OF THE INVENTION
The present disclosure generally relates to a beverage brewing apparatus. More particularly, the present disclosure relates to brewing and straining units of the beverage brewing apparatus.
DESCRIPTION OF THE RELATED ART
Hot beverage brewing machines are developed across the world to prepare instantly made hot beverages such as tea and coffee. It is well known that the hot beverages such as Indian style tea, Indian style coffee, and the like have specific method of preparation. For example, to make the Indian style tea, tea leaves/tea powder must be brewed with water and/or milk to become strong in taste. Further, brewed liquid mixture is poured through a strainer to filter out the tea powder or tea residue. In existing beverage brewing machines, a black tea concoction is instantly available. When a user requests for a tea, the machine dispenses the black tea concoction along with hot milk. Moreover, in few existing beverage brewing machines, a premix powder comprising of a milk powder, a sugar powder, and a tea powder is mixed with hot water to get an instant tea. Typically, the most common feedback from users is that the tea prepared by such machines is not as tasteful and strong as homemade Indian style tea. The user is not able to get his/her preferred taste of beverage with existing brewing machines. Attempts have been made to develop automatic beverage brewing machines for Indian style tea or coffee preparation. However, such machines are limited to dispensing of measured quantity of ingredients to replicate Indian style tea/coffee taste. Moreover, the existing machines fail to make structural changes that would allow for preparation of authentic Indian style tea/coffee. Hence, there exists a need for a brewing machine that prepares authentic Indian style tea/coffee by brewing tea/coffee power/leaves and straining of tea/coffee residue from brewed mixture.
OBJECTS OF THE INVENTION
Some of the objects of the present disclosure are described herein. An object of the present invention is to develop a beverage brewing apparatus that is used to brew coffee/tea and strain residue from brewed mixture to serve Indian style tea/filter coffee.
Another object of the present invention is to develop a brewing unit that is used to brew a mixture of tea/coffee powder, milk, water, and/or, sweetener.
Yet another object of the present invention is to develop a straining unit to strain tea/coffee powder out of the brewed mixture.
Other objects and advantages of the present disclosure will be more apparent from the following description, which are not intended to limit the scope of the present invention.

When a brewing process undergoes in the brewing unit 308, the first and second lid covers 322a and 322b close the openings of the first and second brewing containers 308a and 308b to form an air-tight seal such that the first and second lid covers 322a and 322b avoid spillage of the brewed mixture. The cover plate 314 has a first set of conduits 324a-324b and a second set of conduits 326a-326b that protrude from top surfaces of the first and second lid covers 322a and 322b, respectively. The first set of conduits 324a-324b and the second set of conduits 326a-326b are in fluidic communication with the first and second brewing containers 314a and 314b, respectively. The first set of conduits 324a-324b may be used to intake milk and water into the first brewing container 314a. Similarly, the second set of conduits 326a-326b may be used to intake milk and water into the second brewing container 314b. The first set of conduits 324a-324b may have first and second conduits that are positioned orthogonal to each other and are in fluidic communication with each other. Similarly, the second set of conduits 326a-326b may have third and fourth conduits that are positioned orthogonal to each other and are in fluidic communication with each other. In an embodiment, the cover plate 320 avoids droplets from falling out of the brewing unit 308 during the brewing process of the hot beverage.
FIG. 3E illustrates the drive mechanism 204 and the actuator unit 206 of the brewing unit 308, in accordance with an embodiment of the present invention. The actuator unit 206 includes a drive shaft (not shown) attached to the second cam 318b and a first motor 328 that is attached to the drive shaft via a gear box. The first motor 328 is used to drive the second cam 318b. In an embodiment, the first motor 328 may be a stepper motor or a servo motor. When the drive shaft is rotated by the first motor 328, the second cam 318b rotates along with the drive shaft. The second cam 318b in turn rotates the support frame 312 that is attached to the second cam 318b. Moreover, the first cam 318a rotates with the movement of the support frame 312. When the first and second cams 318a and 318b are rotated, the cover plate 320 that is in contact with the first and second cams 318a and 318b slides towards and away from the first and second brewing containers 314a and 314b based on direction of rotation of the first and second cams 318a and 318b. When brewing process is undergoing in at least one of the first and second brewing containers 314a and 314b, the first and second lid covers 322a and 322b of the cover plate 320 close the openings of the first and second brewing containers 314a and 314b, respectively. When the first and second cams 318a and 318b are rotated in an anti-clockwise direction, the cover plate 320 moves away from the openings of the first and second brewing containers 314a and 314b. Similarly, when the first and second cams 318a and 318b are rotated in a clockwise direction, the cover plate 320 moves towards the openings of the first and second brewing containers 314a and 314b. It is apparent to a person skilled in the art that direction of rotation of the first and second cams 318a and 318b varies with the positioning of the brewing unit 308 with respect to the straining unit 310 and the plurality of containers 302a-302d. The beverage brewing apparatus 100 includes a stopping element 330 that restricts rotation of the second cam 318b. Once the second cam 318b is in contact with the stopping element 330, the microcontroller 202 stops the first motor 328 to halt the movement of the second cam 318b, which in turn halts the movement of the support frame 312 and the cover plate 320.
The drive mechanism 204 moves the brewing unit 308 to various positions within the housing. The drive mechanism 204 may include linear actuators 332a-332b to move the brewing unit 308 within proximity of the plurality of containers 302a-302d and the straining unit 310. In an embodiment, the drive mechanism 204 may also include guide rails (not shown) that help to guide the brewing unit 308 vertically and/or longitudinally within the housing 102. The drive mechanism 204 may further include a second motor (not shown) that controls operation of the linear actuators 332a-332b to achieve vertical and/or longitudinal movement of the brewing unit 308. It will be apparent to a person skilled in the art that any mechanism that aids in rotation and movement of the brewing unit 308 within the housing 102 of the beverage brewing apparatus 100 is covered within the scope of the invention. In another embodiment, the brewing unit 308 may use a peristaltic pump and a pipe instead of the drive mechanism 204 and the actuator unit 206. The peristaltic pump may be used to suck out the brewed mixture in the brewing unit 308 and to drop the brewed mixture on to the straining unit 310 via the pipe. In yet another embodiment, the brewing unit 308 may use a mechanism that allows manual rotation of the brewing unit 308 by the user to dispense the brewed beverage onto the straining unit 310. In yet another embodiment, the brewing unit 308 may use stopper plugs attached to openings at bottom of the first and second brewing containers 314a and 314b. The stopper plugs cover the openings till the brewing process is completed. Once the brewing process is completed, the stopper plugs may be pulled out using a motor/mechanism to allow the brewed mixture to drop on to the straining unit 310 due to its gravity. The microcontroller 202 is connected to the actuator unit 206 and the drive mechanism 204 to control rotation and movement of the brewing unit 308. The microcontroller 202 controls the first motor 328 to control the rotation of the cover plate 320 of the brewing unit 308. Further, the microcontroller 202 controls the second motor to control the vertical and/or longitudinal movement of the brewing unit 308. Moreover, the microcontroller 202 determines position of the brewing unit 308 with respect to the plurality of containers 302a-302d and the straining unit 310 based on the state of the brewing process. The microcontroller 202 controls operation of the brewing unit 308 before, during and after the brewing process.
The microcontroller 202 controls the movement and rotation of the brewing unit 308 according to three states of the brewing process -pre-brewing, during brewing, and post brewing. As shown in FIGS. 3A, 31, and 3J, the position of the brewing unit 308 may vary based on the state of the brewing process of the hot beverage. For example, when the state of the brewing process is the pre-brewing, the brewing unit 308 is in a first position as shown in 3A. In the first position, the brewing unit 308 is in proximity to the plurality of discharge ducts 304a-304d of the plurality of containers 302a-302d. In the first position, the first and second cams 318a and 318b are rotated in the anti-clockwise direction so that the cover plate 320 moves away from the openings of the first and second brewing containers 314a and 314b and vice versa. The ingredients are dispensed into the first brewing container 314a and/or the second brewing container 314b as per user’s selection using the HMI 110. Then, the brewing unit 308 is moved to a second position via the drive mechanism 204 to initiate the brewing process. In the second position, the first and second cams 318a and 318b are rotated in clockwise direction so that the cover plate 320 moves towards the openings of the first and second brewing containers 314a and 314b and vice versa. The milk and water are then dispensed into the first brewing container 314a and/or the second brewing container 314b. The steam is then passed into the first brewing container 314a and/or the second brewing container 314b to initiate the brewing process. In an embodiment, the steam may act a stirrer to stir the ingredients to form a liquid brew mixture. On completion of the brewing process, the brewing unit 308 is moved to a third position that is proximity to the straining unit 310 to dispense the liquid brew mixture. In the third position, the first and second cams 318a and 318b rotate in anti-clockwise direction so that the cover plate 320 moves away from the openings of the first and second brewing containers 314a and 314b and vice versa. This allows the brewing unit 308 to dispense brewed beverage into the straining unit 310. The first and second temperature sensors 220a and 220b and/or the timer 218 to control the operation of the steam generator 212 to start/stop supply of the steam to the first and second brewing containers 314a and 314b. The plurality of photo sensors 216a-216c are positioned to keep track of the movement of the brewing unit 308 within the housing 102. The microcontroller 202 activates the brewing process and dispensing of brewed beverage in the straining unit 310 based on inputs from the plurality of photo sensors 216a-216c.
FIG. 3F illustrates a perspective view of the straining unit 310 of the beverage brewing apparatus 100, in accordance with an embodiment of the present invention. The straining unit 310 is preferably positioned in alignment with the dispenser head 106. The straining unit 310 includes a dispensing platform 334, a straining platform 336, the rotating mechanism 208, and a stopper 338. The dispensing platform 334 includes first and second hemispherical shaped funnels 340a and 340b that dispense strained beverage into the cup placed on the holding platform 104. The arrangement of the first and second hemispherical shaped funnels 340a and 340b is in alignment with that of the first and second brewing containers 314a and 314b, respectively. The straining platform 336 includes first and second bowl shaped strainers 342a and 342b that overlap with the first and the second hemispherical shaped funnels 340a and 340b, respectively. The first and second bowl shaped strainers 342a and 342b are made of any material and shape that has perforations. The size of the perforations can be based on type of ingredients used for preparation of the beverage.
In an embodiment, the rotating mechanism 208 may include a shaft 344 that is attached to an edge of the straining platform 336. The shaft 344 is attached to a third motor 346 via a gear box. The third motor 346 controls the rotation of the straining platform 336 so that residue is disposed into bins after each brewing process. The third motor 346 may be a servo motor or a stepper motor. The stopper 338 stops the rotation of the straining platform 336 after the straining platform 336 rotates to angle more than threshold value to create a sudden jerk to the straining platform 336. The sudden jerk created by the stopper 338 is used to dispose the residue stuck to the first and second bowl shaped strainers 342a and 342b. This allows the first and second bowl shaped strainers 342a and 342b to be reused for the next brew as per selection of user. Further, it is understood that funnels and strainers are of any other shapes in the other alternative embodiments of the present invention. In another embodiment, the straining unit 310 may have an air blower that blows away residue into the bins.
FIGS. 3G-3 J illustrate views 300b-300e of various operations of the brewing unit 308 and the straining unit 310 of the beverage brewing apparatus 100, respectively, in accordance with an embodiment of the present invention. In FIGS. 3G-3J, on completion of the brewing process, the brewing unit 308 is moved to a third position that is proximity to the straining unit 310 to dispense the liquid brew mixture. In the third position, the first and second cams 318a and 318b rotate in anti-clockwise direction so that the cover plate 320 moves away from the openings of the first and second brewing containers 314a and 314b and vice versa. This allows the brewing unit 308 to dispense brewed beverage into the straining unit 310.
The straining platform 336 is used to strain residue within the brewed beverage. The rotating mechanism 208 of the straining platform 336 is used to dispose the residue into the bins 348a-348b. The bins 348a-348b are positioned in proximity to the straining unit 310 within the housing 102 to collect the residue. In the straining unit 310, the brewed mixture is separated from the tea/coffee powder. The straining unit 310 disposes via conduits of the first and second hemispherical shaped funnels 340a and 340b the strained beverage to the cup placed on the holding platform 104.
For example, to prepare tea, the user selects the beverage as tea and the strength of the drink using the HMI 110. Based on the selected options, the microcontroller 202 determines the quantity of ingredients such as water, tea powder, milk and sweetener that to be dispensed into the brewing unit 308. The microcontroller 202 determines whether the brewing unit 308 is at the first position using data collected from the plurality of photo sensors 216a-216c. If the brewing unit 308 is in the third position, the microcontroller 202 controls the drive mechanism 204 to move the brewing unit 308 to the first position. Once the brewing unit 308 is in the first position, the microcontroller 202 controls the actuator unit 206 to rotate the support frame 312 to ensure the cover plate 320 is away from the openings of the first and second brewing containers 314a and 314b. The microcontroller 202 then dispenses the ingredients into the first brewing container 314a by way of the dispensing mechanism 210 through the plurality of discharge ducts 304a- 304d.
In order to initiate the brewing process, the microcontroller 202 controls the drive mechanism 204 to move the brewing unit 308 from the first position to the second position. Once the brewing unit 308 is in the second position, the microcontroller 202 controls the actuator unit 206 to rotate the support frame 312 to ensure the cover plate 320 closes the openings of the first and second brewing containers 314a and 314b. Once the first lid cover 322a closes the opening of the first brewing container 314a, the microcontroller 202 controls the pump system 224 to dispense milk and water into the first brewing container 314a as per user selected options. The microcontroller 202 collects information from the first and second flow meters 222a-222b to measure amount of the water and the milk dispensed to the first and second brewing containers 314a-314b. The microcontroller 202 further activates the steam generator 212 to generate the steam and supply the steam to the first brewing container 314a. The steam stirs the ingredients to form a liquid mixture that is undergoing brewing process. The microcontroller 202 checks temperature readings of the first temperature sensor 220a or tracks time of the timer 218 to provide a stop signal to the steam generator 212. Once the microcontroller 202 determines the brewing process is completed via the temperature readings or time, the microcontroller 202 stops the operation of the steam generator 212.
Once the brewing process is completed, the microcontroller 202 moves the brewing unit 308 from the second position to the third position. At that third position, the microcontroller 202 controls the rotation of the support frame 312 to ensure the cover plate 320 moves away from the openings of the first and second brewing containers 314a and 314b and to allow the first brewing container 314a to dispense the brewed mixture on to the straining unit 310.
When the liquid mixture is poured onto the straining platform 336, the brewed mixture is separated from the tea powder using the first bowl shaped strainer 342a, thereby allowing the strained brew via the first hemispherical shaped funnel 340a to go into a cup/utensil from which the user consumes the beverage. The microcontroller 202 then controls the rotation of the straining platform 336 to dispose residue collected on the first bowl shaped strainer 336a in to the bin 348a. This allows the straining platform 336 to be reused for the next brew as per selection of user.
The brewing unit 308 and the straining unit 310 of the beverage brewing apparatus 100 have several advantages over the existing systems. The brewing unit 308 and the straining unit 310 allow the user to have authentic Indian style tea. The straining unit 310 allows to strain residue from the brewed beverage to prepare authentic Indian style tea. Moreover, use of steam from the steam generator 212 as a stirrer generates freshly brewed tea or coffee.
