The invention describes a device for preparing infüsions, suitable for preparing infüsions in a micro wave. The device comprises: a lowertank transparent to electromagnetic radiation, with a valve; an upper tank screwed to the lower tank; a funnel that connects the tanks; an extraction área containing material to be extracted with filtering means; a cover; and means for making the device leak tight, the device comprising áreas for shielding against electromagnetic waves in the extraction área, the upper tank and the cover. In the preferred embodiments, the device comprises a float, needles and thermal reinforcement áreas. The device allows infüsions to be obtained without the volatile compounds degrading.

A method of delivering a liquid heated to a desired temperature under pressure in a microwave oven uses a device having first and second chambers adapted to receive and hold, respectively, a first and second volume of a liquid, a vapor flow path from the first chamber to the second chamber, and a liquid/vapor flow path from the second chamber to a destination outside of the second chamber. The first chamber liquid receives less microwave energy per volume than the second chamber liquid receives. The device is placed on top of a receiving vessel and placed into a microwave oven, which is activated until the first chamber liquid boils and at least partially turns into gas, flows through the vapor flow path into the second chamber, and forces some of the second chamber liquid through the liquid/vapor flow path to the destination outside of the second chamber.

A device for delivering a liquid heated to a desired temperature under pressure in a microwave oven comprises a first chamber adapted to receive and hold a first volume of a liquid, a second chamber adapted to receive and hold a second volume of the liquid, a vapor flow path from the first chamber to the second chamber, and a liquid/vapor flow path from the second chamber to a destination outside of the second chamber. When the liquid in the first chamber reaches its boiling point and at least partially turns into a gas, at least a portion of the gas flows through the vapor flow path from the first chamber into the second chamber, thereby increasing a pressure in the second chamber. The increased pressure in the second chamber forces the liquid in the second chamber through the liquid/vapor flow path and out of the second chamber.

A beverage maker comprises a heating cavity, a water input configured to be connected to an external water supply and to channel water from the external water supply towards the heating cavity, a water output configured to channel water away from the heating cavity and a means for heating water. The means for heating water is disposed external to the heating cavity and is configured to heat water within the heating cavity. The heating cavity is configured to receive a removable water container so as to form a fluid flowpath from the water input to the removable water container, and from the removable water container to the water output.
