And it is possible to prevent dust from entering the gap.

Next, a case where a grip portion 32 for making it easy to carry the dust collector 10 is provided on the upper surface of the housing 12 will be described. Here, when the upper end portion of the grip portion 32 is on the outermost side in the front view, a lower groove portion 34 having a shape recessed above the lower surface is provided on the lower surface of the housing 12. The position where the lower groove portion 34 is provided is a position corresponding to vertically downward of the grip portion 32 on the lower surface of the housing 12. The lower groove portion 34 is formed wider than the installation area of the grip portion 32 in a plan view and deeper than the protrusion amount from the upper outer peripheral surface 301 in a front view. The grip portion 32 shown in the figure has an inverted U shape and is provided in the vicinity of both side surfaces. Further, it is located between the front wheels 241 and the rear wheels 242 of the caster 24 when viewed in a plan view. As a result, when another dust collector 10 is superposed on the dust collector 10, the grip portion 32 of the lower dust collector 10 is housed in the lower groove portion 34 of the other dust collector 10 above. When the grip portion 32 is housed, the upper outer peripheral surface 301 of the outer frame portion 30 of the dust collector 10 and the lower outer peripheral surface 302 of the outer frame portion 30 of the other dust collector 10 can be brought into close contact with each other without a gap.

In a preferred embodiment, the upper outer peripheral surface 301 and the lower outer peripheral surface 302 may be horizontal planes parallel to each other, and the left outer peripheral surface 303 and the right outer peripheral surface 304 may be vertical surfaces parallel to each other. At this time, the outer frame portion 30 has a square shape or a rectangular shape when viewed from the front. According to this, when the dust collector 10 is installed on the floor, the upper outer peripheral surface 301 and the lower outer peripheral surface 302 are parallel to the horizontal plane, and the intake port 16 is directed in the same direction to stabilize the dust collector 10 in the vertical direction in parallel. Can be placed. Similarly, it is easy to arrange them in parallel in the left-right direction, and it is easy to align the dust collector 10 and to install it. Further, as described above, the air containing dust does not pass through the gap and goes to the back side, and the air containing dust can be sucked more efficiently from the intake port 16.

Next, as a characteristic feature of the present embodiment, a siding surface 28 is provided around the intake port 16 on the front surface of the housing 12. The siding surface 28 is composed of an upper siding surface 281, a lower siding surface 282, a left siding surface 283, and a right siding surface 284. The outermost side of the upper siding surface 281 and the outermost side of the lower siding surface 282 are at the same position in a plan view, and the outermost side of the left siding surface 283 and the outermost side of the right siding surface 284 are the same in the side view. In position. Since the outermost sides are at the same positions as described above, the positions of the outermost sides of the dust collector 10 and the other dust collectors 10 coincide with each other when they are arranged in parallel vertically and horizontally. Therefore, the gap formed between the dust collector 10 on the intake port 16 side and the other dust collector 10 can be completely closed with a sealing tape or the like.

As a preferred embodiment, the upper siding surface 281, the lower siding surface 282, the left siding surface 283 and the right siding surface 284 may be in the same plane. The dust collectors 10 can be arranged in parallel so that the front surface of the housing 12 is flush with each other, and the dust collectors 10 and the other dust collectors 10 have parallel surfaces 28 so that the dust collectors 10 can be easily attached. The upper lining surface 281, the lower lining surface 282, the left lining surface 283, and the right lining surface 284 each have a width of about several cm to serve as a lining allowance, and a lining tape having a general width of 5 cm to 10 cm can be easily attached. Can be done. Further, the curing sheet can also be attached to the sealing surface 28, and by attaching the curing sheet and the sealing tape to the sealing surface 28, the contaminated space can be closed, and a plurality of dust collectors 10 are arranged in parallel to be contaminated. It is possible to suck in the air.

Further, in the dust collector 10 of the present embodiment, the upper surface and the lower surface of the housing 12 may be flat. Further, the left side surface and the right side surface of the housing 12 may be flat. At this time, the upper outer peripheral surface 301 of the outer frame portion 30 and the upper surface of the housing 12 may be in the same plane. Similarly, the lower outer peripheral surface 302 of the outer frame portion 30, the lower surface of the housing 12, and the outer frame The left outer peripheral surface 303 of the portion 30 and the left side surface of the housing 12, and the right outer peripheral surface 304 of the outer frame portion 30 and the right side surface of the housing 12 may be in the same plane. Since they are in the same plane, not only the outer frame portion 30 but also the housing 12 side can be in close contact with each other without a gap, so that dust can be further prevented from entering. Further, if the upper surface and the lower surface are horizontal surfaces and the left side surface and the right side surface are vertical surfaces, installation is easy.

Next, the dust collection mechanism will be described. In the flow of air from the intake port 16 to the exhaust port 20, the filter 18 in the housing 12 passing through may be a plurality of multiple filters 18, and the pre-filter 181 and the casing are located closer to the intake port 16. The main filter 182 may be provided on the side of the body 12 near the exhaust port 20. The edges of the filters 181 and 182 are surrounded by the filter frame 26, making it easy to remove and fix the filters 181 and 182. A net is provided on the filter frame 26 provided in the pre-filter 181 located at the position closest to the intake port 16 to prevent large foreign matter from colliding with the filter frame 26. The direction of air flow taken from the intake port 16 and toward the exhaust port 20 is indicated by an arrow A in FIG.

The pre-filter 181 on the intake port 16 side may be provided with a pre-filter 181 composed of a plurality of filters having different eye sizes from the primary filter 183 and the secondary filter 184. At least, the filter frame 26 of the outermost primary filter 183 close to the intake port 16 is fixed in the housing 12 by a magnet, and the filter frame 26 is fixed in the intake port 16 which is a recessed position from the front surface of the housing 12. Will be done. Further, the other pre-filter 181 and the main filter 182 may be fixed by using bolts. The filter frame 26 is housed in the intake port 16 without a gap.

In the dust collector 10 of the present embodiment, the installation and replacement of the filter 18 in the housing 12 is not performed from the side surface of the housing 12, but is performed from the intake port 16 on the front surface, and the filter 18 is taken in and out from the intake port 16. I do. By attaching and detaching the filter frame 26 fixed by the magnet from the intake port 16, the filter 18 can be easily installed and replaced, and can be fixed in the housing 12, and the filter frame 26 moves even while the dust collector 10 is operating.

Since the filter frame 26 can be attached and detached from the intake port 16, it is not necessary to provide the opening / closing door 52, and since there is no opening / closing door 52, the fixing bracket 54 for fixing the opening / closing door 52 and the hinge (not shown) are not provided on the side surface. Since there are no protrusions on the side surface, the left side surface and the right side surface can be made flat. In particular, it has a great advantage in that the filter can be replaced even when a plurality of dust collectors 10 are arranged in parallel and are in a tight state.

As an example of the filter 18, the primary filter 183 collects relatively large dust having a diameter of about 10 μm or more, and the secondary filter 184 has a relative diameter of about 1 to 10 μm that cannot be collected by the primary filter 183. This is a medium-performance filter 18 that collects dust of a medium size. The main filter 182 is a high-performance filter 18 that collects relatively small dust having a diameter of about 1 μm or less that cannot be collected by the secondary filter 184, such as a HEPA filter 18.

The dust collector 10 of the present embodiment is provided with four casters 24 on the lower surface, the front wheels 241 of the two casters 24 closer to the intake port 16 and the rear wheels 24 of the two casters 24 closer to the exhaust port 20. A ring 242 is provided. The caster 24 is not in contact with the upper groove portion 22 of the other dust collector 10, but is in a state of freely rotating and hanging from the lower surface. The caster 24 rotates 360 °, and even if a part of the rotated caster 24 is in a position where it protrudes from the side surface, the caster 24 can be rotated by applying a force and stored in the upper groove portion 22.

Anti-slip may be provided on the upper surface and the lower surface of the housing 12. As an example, unevenness, protrusions, etc. having a size that does not cause inconvenience when arranged in parallel in the vertical direction may be provided. As a result, it is possible to prevent the front-back and left-right shifts when arranged in parallel.

As shown in FIG. 2, an operation panel 36 and a power cord 38 for operating and operating the dust collector 10 are provided on the back surface. By providing the operation panel 36 and the power cord 38 in the vicinity of the exhaust port 20 from which the clean air is discharged, the operation panel 36 is less likely to be contaminated. At the same time, even if a plurality of dust collectors 10 are arranged in parallel in the vertical and horizontal directions, each dust collector 10 can be operated. Similarly, a differential pressure gauge for displaying the differential pressure between the pre-pass pressure and the post-pass pressure of the filter 18 and indicating an index of the replacement time of the filter 18 may be provided on the back surface. In addition, an air volume adjusting volume for adjusting the amount of passing air, a timer for determining the operating time of the dust collector 10 and automatically starting and ending may be provided, and a power switch.

As described above, according to the dust collector 10 according to the present invention, the dust collector 10 can be arranged vertically and horizontally, and the gap between the dust collector 10 and the dust collector 10 can be made as small as possible. Even if the dust collectors 10 are arranged in parallel, air containing dust does not flow to the exhaust port 20 side through the gap, and a sealing surface 28 is provided to facilitate the tensioning of the sealing tape, so that dust can be prevented from entering more reliably. Can be done. Further, since the filter 18 can be easily removed and installed from the intake port 16 side, the filter 18 can be easily replaced.
