Disclosed herein is a plasma generator capable of stably performing the discharge and an appliance having the same, wherein the plasma generator is configured to generate the discharge by plasma. The plasma generator includes a first case configured to store water to be treated; a second case disposed inside the first case and provided with a body having opposite sides opened, and a cover covering opened one side of the body; a first electrode disposed such that at least thereof is immersed in the water to be treated stored in the first case; and a second electrode disposed inside the second case. The second electrode is apart from a water surface of the water to be treated in an upper side of the water surface of the water to be treated in contact with opened other side of the body opposite to one side of the body.

The present invention relates to a water softening device including: a resin chamber which has an ion exchange resin and softens hard water passing through the ion exchange resin; and electrodes which are arranged by placing the resin chamber therebetween and apply voltages to the resin chamber so as to soften the hard water, and which regenerates the ion exchange resin, wherein the ion exchange resin is a slightly acidic cation exchange resin and/or a weakly alkaline anion exchange resin. The present invention provides the water softening device capable of easily regenerating the ion exchange resin and repeating the softening-regenerating without using chemicals or the like while maintaining the performance of softening water, thereby enabling a continuous use thereof.
