LIQUID STAGNATION PREVENTING DEVICE FOR LIQUID STORAGE TANK OF MULTIPLE TYPE

摘要

PROBLEM TO BE SOLVED: To provide a water storage tank which prevents foul water in the water storage tank by a simple structure and which can be simplified in structure. SOLUTION: A partition wall 12 is provided in the water storage tank 11 to define a first water storage chamber R1 and a second water storage chamber R2. A water feed pipe 13 is inserted in the first storage chamber R1. A water siphon 17 is attached to the partition wall 12. A water rising pipe 17a of the siphon 17 is arranged in the first water storage chamber R1, a conveyance pipe 17b is passed through the partition wall 12, and a water falling pipe 17c is arranged in the second water storage chamber R2. A fixed aperture 18 is provided in the conveyance pipe 17b to cause the siphon principle thereby moving water in the first storage chamber R1 into the second storage chamber R2 by the siphon principle. Since water in the siphon 17 is discharged, water stagnation is prevented.
