Description

The present invention relates to an air purifier that collects dust and tobacco smoke floating in the air.

(B) Prior art As this kind of air purifier, for example, Japanese Patent Application Laid-Open No. 63-88063 (B03C 3/14) is known. This air purifier exhausts ionized air from the top surface of the main unit. Therefore, when the main unit is hung on a wall, the exhausted air causes dust and smoke in a room to be absorbed by the exhausted air. Is charged, so that there is a drawback that charged dust, cigarette smoke, and the like adhere to the wall surface and stain the wall surface.

Therefore, it is conceivable to exhaust the air from the front of the main body. However, this configuration has a drawback that the exhausted air directly hits the user and the user feels cold.

(C) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and does not stain the wall surface even when the ionized air is exhausted by being mounted on the wall surface. An object of the present invention is to provide an air purifier in which a user does not feel cold.

(D) Means for Solving the Problems A first exhaust port formed on at least one surface other than the front surface of the main body to exhaust purified air, and a purified air formed on the front surface of the main body to exhaust purified air. A second exhaust port,
An ion generator formed near the second exhaust port in the main body, for ionizing air exhausted from the second exhaust port, a shutter for opening and closing the second exhaust port, and an ion generator in conjunction with the shutter And control means for controlling the operation of.

A first exhaust port formed on at least one surface excluding the front surface of the main body and exhausting purified air, a second exhaust port formed on the front surface of the main body and exhausting purified air,
An ion generator formed near the second exhaust port in the main body, for ionizing air exhausted from the second exhaust port, a shutter for opening and closing the second exhaust port, and formed on the main body;
A display unit for displaying the operation state of the ion generator and a control unit for controlling the display unit in conjunction with the shutter are provided.

(E) Function When the power is turned on, the air blower is driven to draw in the room air from the air inlet, and the filter body removes dust and cigarette smoke to clean the air. Purified air is the first
Exhaust port and the second exhaust port. At this time, the second
The purified air exhausted from the exhaust port is ionized by the ion generator and exhausted from the front surface of the main body.
Therefore, since the ionized clean air does not hit the wall surface on which the main body is mounted, the ionized dust, tobacco smoke, and the like adhered to the wall surface and do not stain the wall surface. Further, since the air exhausted from the second exhaust port is a part of the exhausted air, the amount of air directly hitting the user is small, and the user does not feel cold. At this time, the control means operates the display means in conjunction with the release of the shutter, and the display means displays that ions are being generated.

Also, if you don't need ionized air,
When the shutter is operated to close the second exhaust port, the control means stops the operation of the ion generator and stops the ion generation display means in conjunction with the shutter.
