Abstract
A beverage brewing device is provided which includes a conventional brewing assembly, and a cooling assembly for brewing a hot beverage and then dispensing the beverage as a hot beverage or diverting it to the cooling system to dispense it as a cold beverage. A switching assembly is provided to permit the user to selectively choose between a hot beverage and cold beverage. The device also provides a novel cooling cartridge which permits the introduction of hot liquid and results in the dispensing of cold liquid from the cold cartridge.
Claims24
A beverage brewing device for dispensing a brewed beverage comprising:
- a housing;
- a water reservoir located within the housing;
- a heater for heating water placed in the reservoir;
- a filter basket for containing beverage media, said filter basket having an outlet;
- means for delivering water from the heater to a location above the filter basket to permit hot water to contact beverage media in the filter basket to brew a beverage;
- a first container for collecting the hot brewed beverage;
- a cooling system located within the housing for cooling the hot brewed beverage, said cooling system including a removable cold retaining element which contacts the brewed beverage to cool said beverage;
- and
- a deflector member movable from a first position which permits the hot brewed beverage to flow from the outlet of the filter basket to the first container, to a second position which directs the hot brewed beverage to the cooling system to reduce the temperature of the brewed beverage.

- wherein the cooling system includes a first stage having a heat sink for air cooling the hot beverage, a second stage including a heat exchange surface downstream from said heat sink, and a third stage having a cold retaining element downstream from the heat exchange surface, said third stage including said outlet to the container for collecting the cooled beverage.
A method of preparing a brewed beverage in an appliance, the method comprising the steps of:
- providing water in a cold water reservoir in the appliance;
- providing beverage media in a filter basket of the appliance;
- heating the water in the appliance and delivering the hot water to the filter basket to brew a hot beverage;
- delivering the hot brewed beverage to a cooling system in the appliance;
- cooling the beverage without refrigeration, said cooling step utilizing a removable cold retaining element;
- and
- delivering the cooled beverage to a container for dispensing.
A beverage brewing device for dispensing a brewed, undiluted beverage comprising:
- a housing including a water reservoir;
- a brewing mechanism;
- means for delivering and dispensing brewed beverage to a container;
- and a three-stage passive cooling system intermediate said brewing mechanism and said container, said cooling system including a replaceable cold retaining element at one of said stages.
