Abstract: In a water passage, a first inflow-side insulator, a second inflow-side insulator, and an electric-discharge water tank are each formed like a sealed container. A tap water pipe is connected to the electric-discharge water tank via inflow-side insulators, and the electric-discharge water tank is connected to water supply headers. The water passage has a hermetic structure that is open to the atmosphere only at a supply opening of each of the water supply headers. Therefore, when pressurized tap water is supplied to the water passage, water flows through the water passage. As a result, restrictions on the positional relationship between a supply target of treated water and a water treatment device are reduced, and the usability of the water treatment device is improved.

Abstract: A water treatment vessel (10) causes electric discharge in water stored therein to produce a sterilizing factor. The water treatment vessel (10) moves in accordance with the level of water in a reservoir (30) to be switched between a discharging state where the water treatment vessel (10) and the reservoir (30) have no communication, and a pair of electrodes (16, 17) are immersed in water in the water treatment vessel (10) to cause the electric discharge, and a draining state where the pair of electrodes (16, 17) come out of water in the water treatment vessel (10) to stop the electric discharge, and water flows out of the water treatment vessel (10) into the reservoir (30). The water supplier (20) supplies water to the water treatment vessel (10) in the draining state, and stop the supply of water to the water treatment vessel (10) in the discharging state.

Abstract: In a submerged discharge device, a pair of electrodes is arranged in a liquid in a reservoir to receive an alternating voltage from an alternating power source, thereby generating a submerged discharge using a discharger arranged in the liquid between the pair of electrodes. A surface of this pair of electrodes has a coating that ensures the submerged discharge generated by the discharger. This may reduce the area of contact between the surface of the pair of electrodes and the liquid in the treatment vessel to reduce the consumption of the pair of electrodes.
