Abstract (en)
[origin: US6427637B1] The invention relates to a steam generator comprising an evaporation tank and several heating elements (2). The evaporation tank consists of an evaporation vessel (1) and a removable limescale rectacle (4) positioned below same. The evaporation vessel (1) is configured as a double-walled vessel having an inner wall (11) and an outer wall (12) which define an outer chamber (13). The inner wall (11) has four inner water-flow openings (111) which connect the interior of the vessel with the outer chamber (13) and the outer wall (12) has outer water-flow openings (121, 122). Water is delivered to and withdrawn from the vessel via the outer flow openings (121, 122), the outer wall (13) and the inner flow opening (111).
