Abstract

An electricity discharge unit applies a voltage from a power supply portion (20) to a first discharge electrode (17) and a first counter electrode (14) which is provided with an opening portion (21) to cause corona discharge in order to generate ion. The first discharge electrode (17) and the first counter electrode (14) are disposed contactless with and orthogonal to each other. A first discharge electrode tip portion (17a) is protruded from the opening portion (21), and a first counter electrode surface (14a) which is the side that the first discharge electrode tip portion (17a) is protruded is provided with a first semiconductive portion (18) which has semiconductivity.

Description

technical field

[0001] The present invention relates to a discharge unit and an air cleaning device using the same. Background technique

[0002] Conventionally, there are known devices that generate ozone, negative ions, and the like by using corona discharge to sterilize and deodorize indoor space. The device has a needle electrode and a ground electrode. Then, a high voltage is applied between the needle electrode and the ground electrode, and corona discharge is generated at the tip of the needle electrode. Ozone and negative ions are generated by this corona discharge (for example, refer to Patent Document 1).

[0003] In the device described in Patent Document 1, in order to prevent sparks of the discharge, a certain distance is required between the needle electrode as the discharge electrode and the ground electrode as the counter electrode. In addition, since the needle electrode and the ground electrode are arranged in parallel, the generation direction of the io...
