Abstract

PURPOSE:To enable air circulation and discharging of air to be separately performed by a method wherein an air circulation passage is branched, the air passage is changed over with a damper. CONSTITUTION:Under a condition that a ventilation air passage 4 is closed by a damper 5, air sucked from a suction port 6 is sent to a blowing port 7 through an air circulation passage 1, passed through a filter 3 and then discharged into a room through a blowing port 7. When the damper 5 is opened, the air circulation passage 1 is closed and the suction port 6 facing to the indoor part comes to communicate with an outdoor part through a ventilation passage 4, resulting in that bad odor within the room can be discharged out of a house by a blower 2. If the blower 2 is rotated in an opposite direction, the suction port 6 and the blowing port 7 are made in opposite relation in turn in the case of performing a ventilation operation, the surrounding air can be introduced into the indoor part.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an air purifying device used for cleaning indoor spaces such as houses, offices, and others.

[Background technology]

BACKGROUND ART Conventionally, in order to remove bad odors and dust indoors, methods such as exhausting the air through ventilation holes provided on the wall, or purifying the indoor air with a deodorizing filter or a collection filter have been adopted.

However, since these air purifying devices only perform either air circulation or exhaust, it is not possible to selectively use air circulation or exhaust depending on the degree of contamination of the indoor air.

[Purpose of the invention]

An object of the present invention is to provide an air cleaning device that can selectively use air circulation and exhaust depending on the degree of contamination of indoor air.

[Disclosure of the invention]

The air purifying device of the present invention includes an air III fan having an inlet and an outlet on the indoor side, a ventilation air duct branched from this air circulation air path and communicating with the outdoors, and the air circulation air It is equipped with an air blower and an air purification filter provided in the air passage, and an air passage switching damper provided at a branch part between the air circulation air passage and the ventilation air passage.

As described above, according to the present invention, the ventilation air path is branched from the air circulation air path, and the damper is used to switch the air path, so indoor air circulation and ventilation can be used selectively. Moreover, compared to the case where the ventilation device and the air circulation device are installed separately, it takes up less space and is more compact, so it can be installed on the ceiling or wall, for example.

FIG. 1 is an explanatory diagram showing the principle of the air purifying device of the present invention. As shown in the figure, the air circulation air passage l has a blower 2 and an air purifying filter 3 housed inside, and both ends are inlet. It has a mouth 6 and a blowout lower. Additionally, air circulation channel 1
A ventilation air passage 4 is formed in a branched manner, and a damper 5 for switching the air passage is provided at the branch portion.

As shown in FIG. 1, when the ventilation air passage 4 is blocked by the damper 5, the air taken in from the intake port 6 is sent to the blowout lower through the air circulation air passage 1, and then passes through the filter 3. It is discharged into the room from the blowout lower.

The filter 3 may have a structure as shown in FIG. 2, which includes a pre-filter 3a and a fiber filter 3b in order from the upstream side of the air.

Deodorizing filters 3c and 3d are arranged.

Here, the pre-filter 3a is for collecting large particles of dirt and dust, and the fiber filter 3b has dense fiber density so that it can collect even very fine dust (about 0.01 microns). . Furthermore, the two deodorizing filters 3C13d are nitrogen-based and sulfur-based filters, respectively, and the nitrogen-based filter removes bad odor components such as ammonia, methylamine, trimethylamine, and nicotine contained in cigarette odor, toilet odor, body odor, etc. Adsorption treatment, sulfur-based toilet odor,
Adsorbs and treats bad odor components such as hydrogen sulfide and methyl mercaptan contained in body odor, rotten egg odor, etc.

Furthermore, when the damper 5 is opened from the state shown in FIG.
It communicates with the outdoors through the air blower 2, and the bad odor inside the room can be discharged outdoors.

Note that if the blower 2 is rotated in the opposite direction, the suction port 6 and the blowout lower will be reversed, and outdoor air can be introduced into the room during ventilation operation.
