An air conditioning rotating body including a rotor having a cylindrical shape. The rotor is housed in a casing so as to be freely rotatable. The casing includes a seal member. The air conditioning rotating body treats air passing through the rotor in an axial direction. The seal member extends in a radial direction of the rotor and separates air passages. An end face of the rotor in the axial direction is provided with at least one spoke in contact with the seal member. A contact point of the seal member with the spoke is configured to move in the radial direction as the rotor rotates.

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

Water treatment device

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.

A water treatment device includes: an insulating divider which divides a space inside a water tank into two treatment vessels adjacent to each other in a horizontal direction, and includes a current carrier which is able to energize water in the two treatment vessels; a treatment unit including a pair of electrodes, a power supply, and a power supply controller; a water supplier which supplies water to each of the treatment vessels; and a draining member which drains water from each of the treatment vessels. The treatment unit includes a detector which detects a level of water in each of the treatment vessels based on an index corresponding to a current value between the pair of electrodes.

Water treatment device and humidification device

A water treatment unit performs a normal operation during which discharge parts generate an electric discharge in a state where water flows into a treatment vessel and treated water flows out of the treatment vessel. When the water treatment unit starts operating, the water treatment unit performs a preparatory operation for a predetermined period of time before starting the normal operation. During the preparatory operation, the discharge parts generate an electric discharge in a state where an outflow of the water from the treatment vessel is stopped. As a result, the water which has been stagnating in the treatment vessel while the water treatment unit is not operating and in which bacteria have grown is sufficiently sterilized.

Water treatment unit

A water treatment system includes a water treatment unit and insulators. The water treatment unit is provided in an intermediate portion of a water passage allowing target water to flow, and produces bactericidal factors in the target water utilizing a discharge. The insulators are provided at an inflow side and an outflow side of the water treatment unit, respectively, and electrically insulate the water flowing to and out of the water treatment unit from the water treatment unit. The insulator at the inflow side sprays the target water to insulate the water. The insulator at the outflow side allows the target water to fall down from the water treatment unit to insulate the water.

A discharge unit includes an alternating high-voltage generator, a pair of electrodes in water, the pair being configured to receive a voltage from the high-voltage generator, and an insulating divider configured to separate the pair of electrodes from each other in the water, and having a small discharge hole defining a path of current to flow between the pair of electrodes. The voltage is applied to the pair of electrodes to generate an electric discharge in the discharge hole.

Discharge unit

Disclosed is a dust collector () that is disposed in an air passageway () to which water droplets () are supplied, and that includes a dust collecting electrode portion () which electrically attracts dust charged in the air. The dust collecting electrode portion () is made of a plate-like member having a mesh-like structure with a plurality of pores, thereby reducing an interfacial tension between the water droplets () adhering on the surface of the dust collecting electrode portion () and the dust collecting electrode portion (). Thus, water droplets are prevented from increasing in size on the surface of a dust collecting electrode, and a decrease in the dust collection capability due to adhesion of dust or the like is reduced.

Dust collector

An air processing device is provided by which a current-carrying section is attached to a casing by an insulating member having a covering section covering an outer periphery face of a current-carrying section and a tube-like section in which a power source-side end of the covering section is supported by a tube bottom section. This consequently secures a long insulating distance from an electric discharge spray section and a charged dust collecting section via the current-carrying section to the casing. As a result, the respective electrodes and the casing can have an improved insulating performance therebetween even under an environment where water droplets are supplied.
