THIS INVENTION IS IN TECHNICAL FIELD OF ELECTRIC HEATING, AND RELATES TO A KIND OF KETTLES FOR BEVERAGE, ELECTRIC WATER KETTLES AND CABLELESS ELECTRIC KETTLES FOR BEVERAGE. ITS AIM IS TO SOLVE THE PROBLEM APPEARING AT EXISTING KETTLES FOR BEVERAGE, I.E. VAPOUR AND WATER GENERATED IN EXISTING KETTLES FOR BEVERAGE FLIES OUT THROUGH TOP PORT OF FUNNEL. THIS MAY NOT ONLY GO THROUGH THE LID OF INNER VESSEL, BUT ALSO REACH ONTO LID OF KETTLE BODY. AS A RESULT, INNER SIDE OF THE LID OF KETTLE BODY WOULD BE WITH TEA OR COFFEE STAINS, AND ITS SURFACE WILL BE VERY HOT TO MAKE ITS USE DIFFICULT AND THERE IS SANITARY PROBLEM DUE TO CONTAMINATION ON SURFACE OF THE LID. KETTLES OF THIS INVENTION CONTAIN AN INNER VESSEL (4) FIXED ON BOTTOM (3) OF THE KETTLE BODY (2) INSIDE THE KETTLE. A FUNNEL (5) IS PROVIDED AT TOP OPENING OF THE INNER VESSEL (4). THERE ARE TWO SEPARATE FILTERING LAYERS INSIDE THE FUNNEL (5): UPPER FILTERING LAYER (6) AND LOWER FILTERING LAYER (7). ON INNER VESSEL (4), THERE IS A CAP (8) COVERING THE OPENING OF THE KETTLE BODY (2) AND HAVING A PIPE (9) FROM CAVITY OF INNER VESSEL (4) TO SPACE BETWEEN KETTLE BODY (2) AND INNER VESSEL (4). KETTLES OF THIS INVENTION ARE EASY TO USE, AND AVOIDS ACCIDENTAL TOUCH OF THE FUNNEL (5) WITH HIGH TEMPERATURE. IT MAY PREVENT FROM BEING BURNED AS WELL AS CONTAMINATION DUE TO TOUCH OF INNER PART OF THE KETTLE BODY (2).
