Title: Hot water storage type electric water heater
Inventor: IMABAYASHI SATOSHI
IPC: F24H9/00
Filed: 2000-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a hot water storage type electric water heater which is capable of storing desired high temperature hot water from the upper portion of a hot water storage tank from the middle to the end of boiling. SOLUTION: A hot water temperature detector 8 is positioned at an upper portion of a heater 2, and diffusion means 11 is provided over a water introduction outlet 10 in an upper portion of the hot water storage tank 1, in which introduced water substantially at the upper portion in the hot water storage tank 1 diffuses substantially along an inner wall of the hot water storage tank 1. Since the cold water introduced from the introduction inlet diffuses along an inner wall at the upper portion in the hot water storage tank 1, detection delay of temperature by the hot water temperature detector 8 is eliminated, and hence driving of a circulation pump 4 is interrupted before the introduced cold water flows through a lower portion of the heater 2 to prevent the temperature of the high temperature water pushed down onto the lower portion of the heater 2.  Accordingly, desired high temperature hot water can be stored from the upper portion of the hot water storage tank 1 from the middle of boiling to the end of the same.
