Abstract

PURPOSE:To obtain an air cleaner capable of easily collecting the locally polluted air so that the range causing the harm of a tabacoo is not extended during smoking and switching into a complete diffusion system in order to collect contaminant diffused in a room when smoking is finished. CONSTITUTION:A suction port 1 and a blowout port 2 are separated in the upper and lower parts. A purifier 4 and a fan 5 are incorporated in a duct 3 communicating the blowout port 2 with the suction port 1. The blowout port 2 is constituted of both a blowout port 2a which forms air flow directed to the suction port 1 along the front face 6 of an air cleaner main body and a blowout port 2b for blowing out the air flow into a room. Damper devices 7a, 7b performing opening/closing operation by a switch or the like are provided on the blowout ports 2a, 2b.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention removes indoor contaminants,
The present invention relates to an air purifier for processing.

[0002]

2. Description of the Related Art There are various types of air purifiers generally available on the market, such as a filter type and an electric dust collecting type. As a method of collecting cigarette smoke, as shown in FIG. The indoor air is agitated by the air flow from the outlet 2, and the cigarette smoke is once diffused into the room to be sucked in through the inlet 1.
A method of removing with a filter or the like placed inside (complete diffusion method) is generally used.

[0003]

The above-mentioned complete diffusion method is suitable for collecting pollutants that have diffused indoors, but a method for collecting locally generated pollutants such as cigarette smoke. As a result, there is a problem in that it is inadequate and inefficient as it causes harm to surrounding people because it is once diffused into the room.

The present invention has been made in view of the above problems. During smoking, it is easy to collect locally contaminated air without spreading the harmful range of tobacco, and when smoking is finished. Another object of the present invention is to provide an air purifier that can be switched to a complete diffusion method in order to collect contaminants that have diffused into the room.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention is that a suction port 1 and a blow-off port 2 are vertically separated and the suction port 1
A cleaning device 4 and a blower 5 are built in a duct 3 that communicates the air outlet 2 with the air outlet 2a that forms an air flow from the air outlet 2 along the front surface 6 of the air purifier body toward the air inlet 2 and the room. The air outlets 2b that blow out to the
The damper devices 7a, 7a which are opened and closed by a switch or the like are shown at b.
It is an air purifier characterized by having b.

[0006]

[Operation] Smoke generated during smoking is the front of the air purifier body 6
Purification device 4 is attracted to the air flow along
And is returned to the room at low wind speed. It should be noted that a part of the blown airflow forms an airflow that directly faces the suction port 2. Further, after the smoking is finished, by switching the damper 7 installed at the air outlet 2, the airflow outlet 2a directed directly to the air inlet 2 is closed and the air outlet speed from the air outlet 2b which blows out into the room is increased,
Smoke that spreads throughout the room by agitating indoor air 2
Inhale more. At this time, by narrowing the outlet 2b with the tamper 7b, it is possible to further increase the blowing speed of blowing into the room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings by embodiments.

As shown in FIGS. 1 and 2, a lower opening is a blow-out opening 2 and a front upper opening is a suction opening inside a vertically long box body having openings in a lower portion and an upper portion of the front surface. The blower 5 is provided so as to be 1, and the air purifying device 4 including a filter or the like for trapping contaminants is provided upstream of the blower 5. Attached to the outlet 2 is a U-shaped guide 8 whose end is in contact with the inside of the box so that a part of the blown air flows toward the inlet 1 along the front of the box so as to sandwich the front. The blower outlet 2 is divided into two blower outlets 2a and 2b, and dampers 7a and 7b having a fulcrum are provided at the inner upper end of the guide 8 so that the divided blower outlets 2a and 2b can be opened and closed. 7a and 7b are switched by a switch or the like.

[0009]

As described above, according to the air cleaner of the present invention, during smoking, as shown in FIG. 3, cigarette smoke is generated by attracting the air flow toward the suction port along the entire surface of the main body of the air cleaner. Are efficiently collected to reduce the harm to the people around them, and after smoking is finished, the smoke velocity diffused into the room without being trapped during smoking is increased by increasing the air flow rate to the room as shown in Fig. 4. Can be collected.
