A machine for brewing coffee or other hot beverages has a hollow base which is open at the underside and has a top portion provided with an opening for a warming plate. The warming plate is assembled with a ring-shaped insulator, an electric heater and a bridge into a unit which is thereupon inserted into the base by way of the open underside before the underside is closed by a detachable bottom. The bridge biases the heater against the warming plate, and its ends are received in openings of the insulator. The central section of the bridge has elastic fingers which engage the toothed peripheral surface of a post at the underside of the warming plate to ensure that the bias of the bridge upon the heater remains unchanged. The base has integral coupling members which extend into openings of the insulator, and the latter has prong-like detent members which engage the marginal portion of the warming plate.

Machine for brewing hot beverages

A machine for brewing coffee, tea or other hot beverages has a hollow base with a top wall beneath the bottom wall of a container for fresh liquid. The top wall has a recess for two annular sealing elements, and the top wall portion beneath the recess has two downwardly extending sleeves. The base confines an electric heater having a liquid admitting inlet connected with one of the sleeves by a first conduit and a liquid discharging outlet connected with a riser in the container by way of a second conduit. The upper end portion of the first conduit extends through the respective sleeve and into the lower part of the corresponding sealing element, and such upper end portion constitutes a cage for the spherical valving element of a check valve which permits fresh liquid to flow from a first nipple of the container toward the inlet of the heater but prevents heated liquid from flowing back into the container. The container has a second nipple which communicates with the lower end of the riser and with the upper end portion of the second conduit. The nipples extend into the corresponding sealing elements.

Machine for brewing coffee, tea and the like

A coffee brewing machine wherein a riser conveys heated liquid into the chamber of a liquid collecting receptacle above a filter holder containing a supply of flavoring agent, such as comminuted coffee beans. The bottom wall of the receptacle has one or more openings which admit heated liquid into the filter holder, and one or more apertures which discharge steam in such a way that the outflowing steam can or must bypass the filter holder. To this end, each aperture defines for steam a path which is inclined with reference to the bottom wall of the receptacle. An aperture can be provided in a hollow flow divider which is installed in the chamber to break up the flow of heated liquid from the riser toward the liquid discharging opening or openings. If the receptacle has a single aperture, the latter is preferably located in or at the central longitudinal vertical symmetry plane of the housing of the machine and causes the steam to leave the receptacle by flowing in such plane. If the receptacle has two apertures, they can be oriented in such a way that one aperture directs steam toward the front side and the other aperture directs steam toward the rear side of the housing.

Machine for brewing coffee and the like

A machine for brewing coffee or other hot beverages has a container for a supply of liquid, a heater, a hollow filter holder which can receive a relatively large quantity of comminuted coffee beans or another flavoring agent, and a riser which conveys heated liquid to the filter holder. The admitted liquid contacts the confined supply of flavoring agent and can be discharged by way of a sealable opening in the bottom wall of the filter holder. If the machine is to brew a single cupful or a similar relatively small quantity of a hot beverage, the holder receives an insert which can hold a small quantity of flavoring agent and is contacted by hot liquid before the liquid enters the interior of the holder where it can be stored or discharged into a cup or another relatively small vessel. The insert has a bottom wall provided with a recess for one or more small bags of flavoring agent, and the bottom wall of the insert has one or more siphons or other types of outlets for evacuation of a freshly brewed hot beverage from the recess.
