Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is suitable for locally removing dust in the air, especially dust generated from a specific part of the device, and does not require much installation space.

Concerning an air purifier that is extremely easy to operate and maintain.

FIG. 1 shows an embodiment of the present invention, in which a blower, an air suction port, a motor, etc. protrude from the top, and panel filters are attached to the four sides.

In the air purifier in this embodiment, the blower 20 and the motor 19 are placed on a frame installed on a metal bottom plate 1 having airtightness, and the upper surface is covered by a plate body 2 having airtightness 4. It has been peeled off, and there are panel type filters on all four sides.
4, 5, and 6 are attached, and it has a box shape except for the top protrusion.

The air purifier according to the present invention has the above-mentioned general structure, but is particularly characterized by the way the filter is attached and the structure of the frame body for that purpose.The details are shown in Figs. 2 and 3. There will be 7 times.

Figure 2 shows a side cross section of the device of the present invention, in which vertical frames are provided at the four corners of the rectangular bottom plate 1 for mounting and fixing filters 3, 4 and 5.6 degrees. One diagonal position is provided with a vertical frame 1°8 in cross section, and the other diagonal position is provided with a vertical frame 1°8 for guiding the filter in the direction of each side (in the direction of the arrow) adjacent to the corner. A gate-shaped vertical frame 12, 13 consisting of two sets of opposite guide plates 9 and 10 and 10 and 11 of cross-sectional shape is provided.

Each side of the bottom surface 1 forming the top surface 2 and the bottom surface, that is, the upper and lower portions between the vertical frames, has a horizontal frame (not shown) for guiding the upper part of the filter having a downward groove and a groove for guiding the lower part of the filter having an upward groove. A horizontal frame 15 is provided.

In order to fix the filters 3, 4, 5, and 6 in a predetermined position, a cross-sectional filter holding device 16 that opens and closes like a hinge is provided at the protruding end of the guide plate 9 of each of the gate-shaped vertical frames 12 and 13. It is provided.

Furthermore, an alarm 22 is provided on the top surface 2 to notify the need for filter replacement or cleaning.

This alarm 22 is a small differential pressure switch (mano star gauge)
When the switch is activated, the indicator lamp 2
3 is lit.

24 is a gauge.

In the above embodiment, the duct installation port 21 shown in FIG.
The tip of the duct attached to the duct is installed in a place where dust, paper powder, etc. are generated, and the device body of the present invention is not far from that place.
It can be installed at an appropriate location that does not interfere with work.

The blower 20 is driven by the rotation of the motor 19, and dirty air containing dust, paper powder, etc. is sucked through the duct installation port 21, and the blower 20 is used to filter the filters 3, 4, 5゜6.
sprayed evenly on the inner surface of the

Dissipated into the room from the filter.

The method for attaching filters 3.4, 5, and 6 to the frame is as follows.

First, leave the filter holder 16 open, insert the tip of the filter 3 between the guide plates 10 and 11 of the gate-shaped vertical frame 12, push it in the direction of the arrow, and make sure that the tip of the filter 3 touches the surface of the vertical frame I. Continue until they touch.

Next, the filter 4 is inserted between the guide plates 9 and 100 of the gate-shaped vertical frame 12, and the receivers of the vertical frame 8 are pushed in until their surfaces come into contact.

Once the filters 3 and 4 are in place, the filter holder 16 is rotated, the end surfaces of the filters 3 and 4 are held down by the surface of the holder 16, and the filters 3 and 4 are fixed with bolts 18.

The filters 5 and 6 are inserted from the gate-shaped vertical frame 13 located diagonally to the gate-shaped vertical frame 12, and similarly fixed with the filter holding tool 16.

The filter installation in the device of the present invention is such that two adjacent filters can be installed and removed in one place, and the two filters are fixed with one filter holder, so the structure can be simplified. In addition, since the filter can be installed and removed horizontally, even if the duct that is part of the device of this invention crosses the top surface, the filter can be removed without any problem. The attachment is removable.

The example shown in FIG. 3 is an example in which the whole is a complete hexahedron, and the upper surface is divided into two parts with holes for ducts.

This upper surface may be an airtight plate, or this upper surface may also be a filter.
