ELECTRIC WATER BOILER

PROBLEM TO BE SOLVED: To provide a convenient electric boiler which is equipped with a liquid pump enabled to securely feed hot water even when bubbles exist in hot water sucked during or immediately after boiling. SOLUTION: A blade 27 is curved projectively to the rotation direction at around an impeller shaft 29. The blade 27 is extended so as to almost vertically face the center line of a guide passage around a delivery 27 when the periphery end part of the blade 27 reaches the delivery 32, Thus, bubbles 38 in liquid 32 are smoothly guided out by the blade 27 toward the periphery of the case 30 and efficiently discharged to the guide passage 33 causing to be securely discharged outside the liquid pump 26.
