Electric filter coffee maker - has vertical through flow heating element in contact with fresh water flow pipe leading to riser pipe

摘要

The coffee maker has a vertical through-flow water heater with a U-shaped tubular electric heating element (4), in intimate contact with the flow pipe (5) for the water between the outlet of the fresh water container (8) and the riser pipe (9) leading to the filter (11). The flow pipe (5) has a non-return valve (7) at the end which is coupled to the fresh water container (8) and is directly coupled to the riser pipe (9) at the other end. Pref. the flow pipe (5) and the tubular electric heating element (4) are formed from a single extruded Al profile with a solid bridge element (6) between the flow pipe (5) and heating element (4). The curved section of the extruded profile pref has an attached temp regulator (15) and microswitch (16) for the electric heating current. ADVANTAGE - Through-flow heater can also be used to heat horizontal hot plate.
