Abstract

A portable coffee brewing device includes a lid pivotally connected to an upper end of the container by a hinge and button. A heating element housing and an electrical component housing is connected to a lower end of the container. A drain is positioned in a bottom wall of the container and is fluidly connected to a heating element positioned within the heating element housing. The heating element is controlled by electrical components positioned in the electrical components housing. A drip tube is fluidly connected to the heating element and the lid. A single serve coffee holding device is positioned below the lid. When the container is filled with fluid and the heating element is powered, heated fluid is forced up the drip tube through the passageway in the lid and into the coffee grounds holding device in a continuous cycle. The device is connectable to an external power source.

Claims

1. A coffee brewing and drinking system, comprising;

a container;

a sleeve positioned within the container;

the sleeve defining a hollow interior;

a heating element wrapped around the sleeve;

the heating element positioned between the container and the sleeve;

a pump fluidly connected to the hollow interior of the sleeve;

a drip tube fluidly connected to the pump;

a lid positioned adjacent the upper end of the sleeve and the container;

the lid configured to move between an open position and a closed position;

a nipple operatively connected to the lid;

a holding device having an opening configured to receive a coffee grounds holding device;

wherein the coffee grounds holding device includes a container that forms a hollow interior, an amount of coffee grounds held within the hollow interior of the coffee grounds holding device, and a cover that covers the hollow interior of the coffee grounds holding device;

wherein the heating element is configured to heat fluid within the hollow interior of the sleeve;

wherein the pump is configured to circulate fluid within the hollow interior of the sleeve to the coffee grounds holding device;

wherein when the lid is in the closed position the nipple penetrates the cover of the coffee grounds holding device thereby providing a fluid passageway into the coffee grounds holding device.

2. The system of claim 1, wherein the heating element is a flexible pad having an embedded heating filament.

3. The system of claim 1, wherein the heating element is a flexible silicon pad having an embedded heating filament.

4. The system of claim 1, wherein the heating element is adhered to the sleeve.

5. The system of claim 1, wherein an insulating tape is positioned around an exterior surface of the heating element.

6. The system of claim 1, wherein a heat transfer paste is positioned between the heating element and the sleeve.

7. The system of claim 1, wherein the drip tube is removable.

8. The system of claim 1, further comprising a pour spout positioned in the lid and configured to facilitate drinking directly from the container.

9. The system of claim 1, wherein the sleeve is removable.

19. The system of claim 1, wherein the holder is positioned between the lid and the container.

20. The system of claim 1, wherein the holder is formed as part of the lid.

10. A wirelessly controlled coffee brewing system, comprising;

a brewing device comprising;

a container;

a sleeve positioned within the container;

a heating element positioned within the container and configured to heat fluid within the sleeve;

a lid positioned adjacent an upper end of the container;

the lid configured to move between an open position and a closed position;

a nipple operatively connected to the lid;

a coffee grounds holding device positioned adjacent the lid;

the coffee grounds holding device having a container that forms a hollow interior, an amount of coffee grounds held within the hollow interior of the coffee grounds holding device, and a cover that covers the hollow interior of the coffee grounds holding device;

wherein when the lid is in the closed position the nipple penetrates the cover of the coffee grounds holding device thereby providing a fluid passageway into the coffee grounds holding device

a temperature sensor,

a controller having a microprocessor and a transceiver;

the controller electrically connected to the heating element and the temperature sensor;

wherein the controller is configured to control operation of the system;

an application;

the application installed on an electronic device and controlled via a user interface;

wherein the application is wirelessly connected to the controller and configured to wirelessly control the brewing device.

11. The system of claim 10, wherein the controller communicates with the electronic device via the transceiver.

12. The system of claim 10, wherein the application facilitates setting a brewing temperature.

13. The system of claim 10, wherein the application facilitates setting a brewing time.

14. The system of claim 10, wherein the application displays a fluid temperature of the brewing device.

15. The system of claim 10, wherein the application informs a user when a fluid temperature reaches a desired range.

16. A method of brewing coffee, comprising the steps of:

providing a coffee brewing device having a container, a sleeve, a heating element, a drip tube, a nipple and a lid that is configured to move between an open position and a closed position;

filling the sleeve with water;

placing a coffee grounds holding device in an opening in a holding device adjacent the lid, the coffee grounds holding device having a container that forms a hollow interior, an amount of coffee grounds held within the hollow interior of the coffee grounds holding device, and a cover that covers the hollow interior of the coffee grounds holding device;

closing the lid;

penetrating the cover of the coffee grounds holding device with the nipple thereby forming a fluid passageway into the coffee grounds holding device;

heating the water with the heating element;

flowing the water from the sleeve, through the drip tube, and into coffee grounds holding device thereby creating coffee;

drinking the coffee directly from the container.

17. The method of claim 16, wherein the heating element is wrapped around the sleeve and is positioned between the container and the sleeve.

18. The method of claim 16, wherein the coffee brewing device further comprises a pump fluidly connected to the sleeve and the drip tube.
