Coffee maker with heater and filter

Abstract

Abstract A COFFEE MAKER INCLUDES A CENTRALLY ARRANGED FILTER SUPPORT FOR RECEIVING A FILTER ELEMENT AND A CHARGE OF COFFEE, WITH A CONTAINER DEFINING AN ANNULAR SPACE THEREAROUND FOR WATER WHICH IS CLOSED BY A COVER WHICH EXTENDS OVER THE ANNULAR SPACE AND THE TOP OF THE FILTER. A WATER HEATING TUBE IS ARRANGED WITHIN THE ANNULAR SPACE WHICH INCLUDES A HEATER FOR HEATING THE WATER WHICH IS DELIVERED FROM THE LOWER END OF THE TUBE THROUGH A RELIEF VALVE CONNECTING INTO THE ANNULAR WATER SPACE. THE TOP OF THE TUBE EXTENDS FROM THE ANNULAR SPACE AROUND THE FILTER TO AN OVERHEAD DISCHARGE ONTO A SCREEN ARRANGED ABOVE THE FILTER. THE HEATED WATER WHICH IS DISCHARGED FROM THE TUBE IS DISTRIBUTED BY THE SCREEN OVER THE COFFEE AND PERMITTED TO FILTER DOWNWARDLY INTO A RECEPTACLE WHICH IS LOCATED BELOW THE DEVICE. THE WATER HEATING TUBE INCLUDES AN ELECTRIC COIL HEATER THEREAROUND AND IT IS ARRANGED IN A SLEEVE AND SEPARATED FROM THE ANNULAR WATER SPACE BY AN ANNULAR PACKING WHICH SURROUNDS THE HEATING TUBE. ENTRANCE TO THE SLEEVE AND THE HEATING TUBE IS THROUGH A RELIEF VALVE WHICH CLOSES WHEN THE PRESSURE OF THE WATER WITHIN THE HEATING TUBE REACHES A PREDETERMINED AMOUNT, BUT WHICH OPENS AGAIN ONCE THE CHARGE OF HEATED LIQUID IS DISCHARGED UPWARDLY AND OVER AND INTO THE CHARGE OF COFFEE ARRANGED ABOVE THE FILTER.
