Abstract

PURPOSE:To prevent the stain of a wall surface by providing a filter for cleaning air and providing an exhaust port on the surface of a main body and equipping an ion generator in the vicinity of the exhaust port. CONSTITUTION:The air in a room is sucked from a suction air port 2 by driving a fan. Dust and smoke, etc., in the air are electrified by an ionization part 8 and removed by a removing filter 12 and the air is cleaned. This cleaned air passes through a draft air duct and is exhausted through a first exhaust port 13. Furthermore the cleaned air is branched from the draft air duct and exhausted through a second exhaust port 15. The cleaned air exhausted through the second exhaust port 15 is electrified by an ion generator and exhausted from the front face of the main body 1. Thereby it is unnecessary that a shutter and the ion generator are individually operated and an air cleaner can be made simple.

No. 3 Ko% (8O3C3/14) is known. This air purifier is designed to exhaust ionized air from the top of the main unit, so especially when the main unit is hung on a wall, the evacuated air can cause the inside of the room to be damaged. Since dust, cigarette smoke, etc. are transferred to the Teiden, there is a drawback that the emitted dust, cigarette smoke, etc. adhere to the wall surface and stain the wall surface.

Therefore, it may be possible to exhaust the air from the front of the main body, but this configuration has the disadvantage that the exhausted air directly hits the user, making the user feel cold.

(c) mg to be solved by the invention The present invention has been developed in view of the above-mentioned drawbacks, and even when it is attached to a wall and exhausts ionized air, the wall does not get contaminated, and the exhaust air does not pollute the wall. To provide an air purifier that does not make a user feel cold.

(d) Means for Solving the Problems A first exhaust port is provided on at least one surface other than the front surface of the main body to exhaust purified air, and a first exhaust port is formed on the front surface of the main body to exhaust purified air. a second exhaust port for exhausting air;
an ion generator that is formed near a second exhaust port in the main body and ionizes air exhausted from the second exhaust port;
A shutter for opening and closing the twelve exhaust ports and a control means for controlling the operation of the ion generator in conjunction with the shutter are formed.

a first exhaust port formed on at least one surface other than the front surface of the main body for exhausting purified air; a second exhaust port formed on the front surface of the main body for exhausting purified air; an ion generator formed near a second exhaust port for ionizing air exhausted from the second exhaust port;
A shutter for opening and closing an exhaust port of the ion generator, a display means formed on the main body for displaying the operating state of the ion generator, and a control means for controlling the display means in conjunction with the shutter.

(E) When the operating power is turned on, the blower is activated and the air in the room is taken in from the intake port, and the integrated filter removes dust, cigarette smoke, etc. and purifies the air.The purified air is % of the first exhaust port is exhausted from the second exhaust port.At this time, the purified air exhausted from the second exhaust port is ionized by the ion generator and exhausted from the front of the main body. , Ionized clean air: Since the main body is not drawn to the wall surface on which the main unit is attached, ionized dust, cigarette smoke, etc. from the ionized clean air will not adhere to the wall surface and contaminate the surface. No, and since the air exhausted from the 41#x port of 11I2 is part of the air being exhausted, the amount of air that hits the user immediately after 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.

In addition, when ionized air is not required, if the second exhaust port is closed by operating the shutter, the control means stops the operation of the ion generator in conjunction with the shutter, and the ion generation display means stop.
