DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described. The present invention is realized in a water softener in which a raw water tank and a salt water tank are arranged above a resin cylinder filled with an ion exchange resin. . In the water softener according to the present invention, the raw water tank and the salt water tank have an integral structure, and the salt water tank is partitioned into a salt receiver and a salt water passage provided with a salt water outlet. A partition plate is provided.

In the present invention, a plurality of partition plates are provided in a zigzag manner at predetermined intervals in the salt water flow path between the salt water outlet and the salt receiving portion, and the respective partition plates are arranged in a zigzag shape. This forms a labyrinth structure. With this labyrinth structure, the salt water flowing into the salt water channel from the salt receiver of the salt tank retains impurities and undissolved salt mixed in the salt water at each corner of each partition plate. As a result, the salt water containing no impurities flows out from the salt water outlet. Therefore, the pipes and valves connected to the salt water outlet are not clogged.

[0007] It is also preferable to adopt a weir plate structure in which partition plates are arranged in parallel at a predetermined interval on the bottom surface of the salt water flow path portion. By arranging each of the partition plates in a barrier plate structure, impurities and undissolved salt in the salt water flowing from the salt storage unit collide with each partition plate serving as a barrier plate, or impinge on each partition plate. The water is blocked and settles in the flowing water, and the settled impurities and the like remain at the root of each partition plate, and salt water free of impurities and the like flows out of the salt water outlet.
