ABSTRACT:
A combined water heating and vessel support plate for supporting the vessel of a beverage preparation device includes a heating slab having a water flow-through duct constituted by longitudinal apertures in a plurality of prismatic (preferably rectangular) heating-plate segments which are clamped together side-by-side with PTC ceramic electrical resistance heating elements interposed between them. The duct is completed by connecting the apertures externally by tubes or by duct-incorporating end caps on the heating plate to form a continuous flow path from an inlet to an outlet. Various clamping arrangements, preferably with some resilience, are described, as are the use of inter-segment filling materials and electrically insulating materials with good heat-conducting properties, also the selection and positioning of the heating elements to achieve a desired heating effect. The top surfaces of the segments are coplanar and form a flat vessel support surface for heating a vessel placed thereon.
