BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an air purifier suitable for an operating room of a hospital or a workplace where ultra-precision work is performed.

[0002]

2. Description of the Related Art In a conventional air cleaner, a separate air inlet and an air blowing / blowing unit shown in FIG. 4 are connected by a duct, or the air suction unit, the air blowing unit and the air blowing unit shown in FIG. Some were integrated.

[0003]

[Problems to be Solved by the Invention]
Since there is only one suction port, it is difficult to adjust the air flow distribution in the room, and because it is a set of suction, air blow, and blowout units that are separate units, the form is large and there are two mounting points. In some cases, it is divided into two parts, which occupies a large installation space, which makes it difficult to design the air cleaner and causes trouble in construction.

An object of the present invention is to improve the air flow distribution in the room, to make the whole compact and to simplify the installation work.

[0005]

In order to achieve the above object, the air purifier of the present invention has a box-shaped main body and a front panel of the main body which can be divided, and an ultra-high performance is provided in the center of the panel. A blower outlet with a filter attached detachably is formed, suction ports are provided at multiple locations around this blower outlet, and a pre-filter is attached to this suction port or suction passage. Behind the exit, a muffler with a baffle and a blower were installed in sequence.

A suction gallery or a suction variable louver may be attached to the suction port of this air purifier.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. 1 is a central longitudinal sectional view showing an embodiment of the air cleaner of the present invention, and FIG. 2 is a front view of the same. In the figure, (1) is a main body, and a sound absorbing material (1a) is stretched on the inner surface of the box type. The panel (2) is detachably attached to the main body (1) on the front surface thereof.

(3) is an air outlet, which is formed in the center of the panel (2), and an ultra high performance filter (4) generally called a HEPA filter is detachably fitted into the air outlet (3). In addition, suction ports (5) are provided at a total of four positions on the left, right, top and bottom of the air outlet (3) so as to surround the air outlet (3), and each air inlet (5) has a pre-filter (6). The attached suction gallery (7) is fitted. This suction port (5) may be left, right, up and down only at two places, or may be left, right, up and down at four places, and may be selected depending on the installation conditions.

A muffler (8) is mounted behind the suction port (3) in the main body (1) and has a baffle (9) parallel to the suction port (3) inside. (10) is a turbofan, which is mounted behind the silencer (8). (11) is an outside air intake, which is provided with an air volume control valve (12).

In the air purifier of the present invention, the main body (1) and the panel (2) can be divided, so that the panel (2) can be attached even after the ceiling board is stretched.

Thus, by driving the turbo fan (10), coarse dust is removed from the indoor contaminated air by the pre-filter (6) from the four inlets (5) on the left, right, top and bottom, and the main body (1) is removed. To the baffle (9) of the muffler (8) by sucking in some fresh air from the outside air intake (11) at the same time, mixing it with the polluted air in the room, passing through the turbofan (10). By eliminating noise and circumventing the baffle (9), it diffuses and uniformly passes through the entire surface of the ultra-high performance filter (4) to remove fine dust and clean the air from the air outlet (3). Blow out indoors.

FIG. 3 is a central longitudinal sectional view similar to FIG. 1 showing another embodiment, in which a variable louver (1) for sucking into a suction port is used.
3) equipped with a pre-filter (6)
Is attached to the inlet of the suction passage (14) of the main body (1), and other configurations are the same as those in FIG. 1, and the suction angle of each suction port is adjusted by adjusting the opening degree of the suction variable louver (13). The air intake distribution can be adjusted by adjusting the suction amount.

FIG. 4 shows an example of a conventional air purifier, in which a blow-out unit (A) and a blower unit (B) are integrated side by side, and another suction port (C ') and a blower unit (B). ) Is connected by a duct (D), and an outside air duct (E) is connected to this duct (D), and when the blower unit (B) is started, the polluted air in the room is sucked from the suction port (C ′), and at the same time, Fresh air is sucked from the outside air duct (E), passes through the duct (D), passes through the blower unit (B), and is blown out from the blowout unit (A) through the ultra-high performance filter (F) into the room.

In this case, since the blow-out unit (A) and the blower unit (B) are separate and attached side by side, the form becomes large, occupying a wide installation place, and the suction port (C '). Since it is attached to another place and tied with the duct (D), it takes time and labor for the construction work, and the suction port (C ') is only one place, which makes it difficult to adjust the air flow distribution. It was

FIG. 5 shows another example of the conventional air purifier, in which the blow-out unit (A), the blower unit (B) and the suction unit (C) are attached side by side to form an integral unit. ) Is connected to the outside air duct (E),
When the blower unit (B) is activated, indoor polluted air is sucked in from the suction unit (C), and at the same time, the outside air duct (D)
The fresh air is sucked into the room, blown through the blower unit (B), and then blown out from the blowout unit (A) through the ultra-high performance filter (F) into the room.

Also in this case, as in the conventional example shown in FIG. 4, it is difficult to occupy a wide installation space due to the difficulty of the air flow distribution due to the single suction port and the large shape.

[0017]

According to the air cleaner of the present invention described above, the air intake distribution is improved by providing the suction port at two or more places around the air outlet, and if the louver is used for the suction port. The suction angle and the suction amount can be adjusted, and the fine air flow distribution can be adjusted, and the noise reduction can be achieved by providing a silencer.

Further, since the whole structure is compact and compact, the space occupied by the installation is small, the freedom of air clean design is widened, the installation work is easy and the labor is saved, and the panel can be separated from the main body. Therefore, the panel can be attached after the interior material is stretched, and after the attachment, the ultra-high performance filter can be replaced, the equipment can be maintained, and each part can be easily cleaned from the room.
