Description

Ionizer unit

FIELD OF THE INVENTION The present invention relates to an ionizer unit that generates ionized substances.

BACKGROUND OF THE INVENTION An example of an ionizer device equipped with an ionizer unit has been described in Japanese Patent Application Laid-Open No. 9-137634. This ionizer device includes one ionizer unit with a linear discharge electrode. In this ionizer unit, since the discharge electrode is configured in a linear shape, the ionized substance is generated along the linear discharge electrode. Therefore, compared with the generation of ionized substances by locally provided discharge electrodes, ionized substances can be generated widely and uniformly, even when there is a certain range of the static elimination target in the static elimination target. It becomes possible to perform the static elimination function without deviation.

In this type of ionizer unit, the voltage supplied by the power source is generally boosted by a step-up transformer and then supplied to the ionizer unit through a power supply line. Therefore, there may be a situation where the installation position of the ionizer unit is restricted due to the thickening of the power supply line, or there may be a problem of radiation noise generated by the power supply line.

Summary of the Invention Therefore, it is desirable to realize an ionizer unit that is easy to install and does not easily cause radiation noise problems. Means to solve the problem

The ionizer unit in view of the above, as one aspect, includes: a rectangular electrode substrate; a linear discharge electrode, which is arranged on the surface of the electrode substrate and is formed as one continuous strip along the longitudinal direction of the electrode substrate Linear; a step-up transformer for step-up, electrically connected to one of the aforementioned linear discharge electrodes, and set to be dedicated to the one aforementioned linear discharge electrode; and a box body that integrally houses the aforementioned electrode substrate and the aforementioned step-up transformer.

According to this configuration, in the ionizer unit, the voltage before being boosted by the boosting transformer is supplied. Therefore, compared with the case where the voltage from the power supply is boosted by a step-up transformer and then supplied to the ionizer unit through the power supply line, the voltage through the power supply line becomes lower. Therefore, the thickening of the power supply line can be suppressed, and the ionizer unit that is not easily restricted in the installation position of the ionizer unit can be made, and the radiation noise generated by the power supply line can be reduced, and the power supply line can be suppressed. The influence of radiated noise on the outside. Furthermore, since the electrode substrate and the step-up transformer are integrally housed in the box body, the wiring or the substrate through which the voltage boosted by the step-up transformer passes is shortened and can be housed in the box body. Therefore, the influence of radiation noise generated by the ionizer unit to the outside can also be suppressed.
