PURPOSE:To prevent generation of bubbles by weakening the blow force of water as well as mixing of low-temperature water with high-temperature water by a method wherein an inclined part is provided at the lower end of a water feeding tube and feed water is discharged downward obliquely to arrive at the level thereof in a hot-water and water separating tube under being bounced by the inner wall of the tube. CONSTITUTION:The water feeding tube 3 is arranged at the upper part of the hot-water reserving tank 1 so as to face the discharging port thereof toward the inside of the hot-water and water separating tube 4 and is provided with the inclined part 5 at the lower end thereof so as to discharge water downward obliquely toward the inner wall of the tube 4 and collide it against thereto while the discharged low-temperature water arrives at the water level in the tube under being bounced by the inner wall surface of the tube 4. The amount of feeding water is controlled by the motion of a ball-tap valve 6, which is caused by the lowering of the water level. According to this method, even in case the water is discharged vigorously because a water feeding pressure is high, the blowing force of the water is weakened when it arrives at the water level since it is weakened by the inclined part at the lower end of the tube 3 as well as the inner wall of the tube 4, and generation of bubbles is prevented, accordingly, the low-temperature hot-water may be prevented from being overflowed from the tube 4 by the bubbles and mixed with the high-temperature hot-water, therefore, the temperature of hot- water from a hot-water supplying port 2 will never by lowered. |
