ABSTRACT:
A machine for brewing coffee, tea or other hot beverages has a hollow housing for a water heater which is disposed beneath and can directly heat a warming plate serving to support a pot, a carafe, a vacuum bottle, a cup or another vessel for a freshly brewed beverage which is being discharged from the chamber of a filter holder above the warming plate. If the nature of the material of the vessel is such that the bottom wall of the vessel should not be heated to an elevated temperature, the operator inserts a distancing element between the warming plate and the casing of the heater. The area of contact between the heater and warming plate on the one hand, and the distancing element on the other hand, can be selected with a view to ensure a desirable reduction from that rate of heat tranfer which takes place when the heater is in direct and large-area contact with the warming plate. The distancing element can be made of a single piece of metallic wire and is provided with a male locating member fitting into a socket in the casing of the heater to ensure that the distancing element is held in an optimum position between the heater and the warming plate.
