Embodiment Construction

[0070] Hereinafter, embodiment of the air cleaner of this invention is demonstrated based on drawing.

[0071] (Structure of Air Cleaner 1)

[0072] An air cleaner 1 according to an embodiment of the present invention is shown in figure 1 . The air cleaner 1 is a ground-mounted air cleaner installed indoors on the ground in order to keep indoor air clean and improve indoor comfort. The air cleaner 1 has a main body 2 and an electron current discharge unit 63 (refer to Figure 8 , Figure 9 ). The main body part 2 can be divided front and back, and the first main body part 3 is provided on the rear side, and the second main body part 4 is provided on the front side. The electron current discharge unit 63 is located at the upper right of the main body 2 in a front view and extends forward and backward.

Abstract

Provided is an air cleaner capable of stabilizing the exhibition of a function even in case the function adopted is a cleaning function, the exhibition of which may be reduced in efficiency by a contaminant in the air. A body portion (2) has an inlet port (13, 14) and an outlet port (12). A main air passage connects the inlet port (13, 14) and the outlet port (12). An air cleaning unit (40) is arranged on the main air passage to clean the air to be passed therethrough. A bypass air passage bypasses the space on the inlet port side and the space on the outlet port side in the main air passage. A streamer discharge unit (63) is arranged in the bypass air passage to produce active seeds. A blowing fan (31) is disposed in the body portion (2) and is rotationally driven to generate a main air flow (F1) in the main air passage from the inlet port (13, 14) to the outlet port (12) and a bypass air flow (F2) in the bypass air passage from the space on the side of the outlet port (12) to the space on the side of the inlet port (13, 14).

Description

technical field [0001] The present invention relates to air purifiers. Background technique [0002] Conventionally, there is an air cleaner that returns air purified by removing odorous components floating in indoor air, dust, bacteria, viruses, etc., back into the room. In such an air cleaner, odor components, dust, viruses, etc. are decomposed, killed, or inactivated by ozone. [0003] On the other hand, in recent years, for example, like the air cleaner described in Patent Document 1 shown below, it has been proposed to provide a stage for removing dust that is cleaned using an electrostatic precipitator filter and to float in the air. Dust, odor components, viruses, etc. are adsorbed on the adsorption part, and at the same time, active species of high-speed electrons, ions, and hydroxyl radicals with high reactivity are generated and sent to the adsorption part for purification. There are multiple purification stages. [0004] Patent Document 1: Japanese Patent Laid-O...
