Description

Technical Field

[0001] The present invention relates to a dust collection unit.

Background Art

[0002] Conventionally, in renovation work while using a living room, when a worker leaves the renovation work area and returns to the building operation area or passes through the building operation area, it is necessary to remove dust, powder, etc. adhering to the work clothes. Although dust removal is carried out using a blower or the like in the renovation work area, the dust removed from the work clothes and the body dances in the renovation work area and diffuses into the air. The diffused dust falls on the floor surface in the renovation work area, and the dust adheres to the back of the worker's work shoes. Therefore, when the worker leaves the renovation work area, they remove the dust adhering to the sole of the shoe with a foot wiping mat or the like and then leave. When removing dust, the periphery of a blower or the like is simply covered with a sheet, but the scattering of dust cannot be sufficiently suppressed, and it scatters around. Therefore, a dust treatment device for treating dust has been developed (see, for example, Patent Document 1).

Problems to be Solved by the Invention

[0004] Since the simple dust treatment device of Patent Document 1 is large-scale, in a site where the renovation work area frequently moves, such as in renovation work, it takes time to install the device, and there is a risk of affecting the construction period of the renovation work.

[0005] The present invention has been made in view of the above-described problems, and an object thereof is to provide a dust collection unit that can be easily assembled and transported.

Means for Solving the Problems

[0006] To achieve the above object, the dust collection unit according to the present invention includes a frame portion composed of a rod-shaped member and a connecting member that connects the rod-shaped members, and a wall member, a floor member, and a ceiling member disposed so as to cover the frame portion. The dust collection unit is assembled with a dust collection box and a dust collection device connected to the dust collection box. The dust collection box is configured to be assembled and disassembled. The wall member, the floor member, and the ceiling member are resin plate-shaped members, and the plate-shaped members are detachably connected to each other by a hook-and-loop fastener.

[0007] According to the present invention, since the wall member, the floor member, and the ceiling member constituting the appearance of the dust collection unit are made of resin plate-shaped members, and the plate-shaped members are detachably configured by a hook-and-loop fastener, they can be easily assembled and disassembled. Further, since the wall member, the floor member, and the ceiling member are made of resin plate-shaped members, the dust collection unit can be lightened and can be easily transported.

[0008] Further, in the present invention, the rod-shaped member may be a resin pipe, and the connecting member may be a pipe socket.

[0009] By configuring in this way, the frame portion can also be easily assembled and disassembled, and can be lightened and easily transported.

[0010] Further, in the present invention, an adhesive mat may be provided on the upper surface of the floor member.

[0011] By configuring in this way, the dust floating in the dust collection box can be adhered to the adhesive mat. Therefore, when the user exits from the dust collection box, the risk of taking the dust out can be reduced.

[0012] Further, in the present invention, a pressure adjustment portion may be provided on the wall member.

[0013] By configuring it in this way, it is possible to maintain the pressure balance between the inside and the outside of the dust collection box through the pressure adjustment unit.

[0014] Further, in the present invention, the pressure adjustment unit may have a mechanism that opens toward the inside of the dust collection box.

[0015] By configuring it in this way, when the inside of the dust collection box becomes negative pressure compared to the outside, the pressure adjustment unit can function to introduce necessary air into the dust collection box. Therefore, it is possible to maintain the pressure balance between the inside and the outside of the dust collection box without leaking the dust inside the dust collection box to the outside.

[0016] Further, in the present invention, a blower device for blowing air into the dust collection box may be attached to the dust collection box.

[0017] By configuring it in this way, the dust adhering to the user can be efficiently removed by the blower device.

[0018] Further, in the present invention, an operation unit for operating the operation of the dust collection device and the blower device may be provided inside the dust collection box.

[0019] By configuring it in this way, the user inside the dust collection box can switch the ON / OFF of the dust collection device and the blower device at their own timing.

[0020] Further, in the present invention, a corner member may be provided at the corner of the dust collection box.

[0021] By installing the corner member in this way, it is possible to prevent dust from leaking from the connection part of the resin plate members. In addition, the structural strength of the dust collection box can be increased.

Modes for Carrying Out the Invention

[0024] Hereinafter, the dust collecting unit according to the embodiment of the present invention will be described with reference to FIGS. 1 to 7.

[0025] As shown in FIGS. 1 and 2, the dust collecting unit 1 is, for example, a unit for removing dust, powder, etc. attached to work clothes when a worker leaves the renovation work area and returns to the building operation part, or passes through the building operation part during renovation work while using a living room. Note that FIG. 2 shows the hidden part as a solid line for convenience.

[0026] The dust collecting unit 1 is a box-shaped unit that can be easily assembled and disassembled, and is formed, for example, in a size for one worker (user).

[0027] The dust collection unit 1 includes a framework part 2 that serves as the framework of the unit, a wall member 3, a floor member 4, and a ceiling member 5 that are arranged to cover the outside of the framework part 2, a dust collection box 7 assembled from these, a dust collection device 8 connected to the dust collection box 7, and a blower device 9.

[0028] The framework part 2 includes a rod-shaped member 21 made of resin piping and a connecting member 22 made of a resin pipe socket that connects adjacent rod-shaped members 21. The rod-shaped member 21 and the connecting member 22 are assembled only by fitting without using an adhesive or the like. By configuring it in this way, assembly and disassembly can be easily performed. The rod-shaped member 21 is arranged along the outer shape of the dust collection box 7, and rod-shaped members 21A for reinforcement (see FIGS. 4 and 5) are arranged in a substantially horizontal direction at predetermined intervals in the height direction.

[0029] The wall member 3 is composed of a plate-shaped member made of resin. The wall member 3 covers all four sides of the box-shaped dust collection box 7. The wall member 3 is composed of, for example, plastic corrugated board (hereinafter referred to as "plastic corrugated") 31. The plastic corrugated 31 is, for example, of a size with a width of about 750 to 900 mm and a height of about 750 to 900, and a plurality of these are used to form the wall member 3. As shown in FIG. 6, adjacent plastic corrugated 31 in the height direction are connected by a hook-and-loop fastener 32. The plastic corrugated 31 arranged in the vertical direction are provided with hook-and-loop fasteners 32 so as to overlap by, for example, 180 mm each in height.

[0030] As shown in Fig. 7, at the corner of the wall member 3, two plates 31 are butted against each other on the outside of the framework member 2. A corner member 33 is arranged so as to cover the butting portion between the two plates 31 at the corner. The corner member 33 is formed of the same material as the plate 31. The corner member 33 is formed in an L shape. The corner member 33 and the plate 31 are connected by a hook-and-loop fastener 34. The corner member 33 may be arranged over the entire length in the height direction of the dust collection box 7, or may be arranged at predetermined intervals in the height direction. By configuring in this way, it is possible to suppress the leakage of dust from the corner portion.

[0031] The floor member 4 is composed of a resin plate-like member. The floor member 4 covers the bottom surface of the box-shaped dust collection box 7. The floor member 4 is composed of, for example, the same plate 41 as the wall member 3. An adhesive mat 43 is provided on the upper surface 42 facing the inside of the dust collection box 7 in the floor member 4. The adhesive mat 43 has an adhesive force sufficient to adsorb dust etc. attached to the back of the worker's shoes. A corner member 33 is appropriately attached at the boundary between the floor member 4 and the wall member 3 to connect the floor member 4 and the wall member 3.

[0032] The ceiling member 5 is composed of a resin plate-like member. The ceiling member 5 covers the top surface of the box-shaped dust collection box 7. The ceiling member 5 is composed of, for example, the same plate 51 as the wall member 3. A corner member 33 is appropriately attached at the boundary between the ceiling member 5 and the wall member 3 to connect the ceiling member 5 and the wall member 3.

[0033] As shown in Fig. 3, the dust collection box 7 is provided with a door 71 through which a worker (user) enters and exits. The door 71 is provided on one of the four surfaces (front surface) of the wall member 3. The door 71 is formed of the plate 31. The opening and closing mechanism of the door 71 may be any one. For example, a fold may be made in the plate 31 on the hanging side to replace the hinge. A magnet (not shown) is attached to the door tip side of the door 71 so that it can be sealed when the door 71 is closed.

[0034] As shown in FIG. 5, an outside air intake 61 is formed on the surface (rear surface) facing the surface where the door 71 is provided. The outside air intake 61 is an opening formed in a part of the pradhan 31 on the rear surface. Inside the box of the outside air intake, a pressure adjustment plate 62 formed of the pradhan 31 that is slightly larger than the opening is attached so as to block the opening (outside air intake 61). The pressure adjustment plate 62 is connected to the pradhan 31 constituting the rear surface of the wall member 3 by a surface fastener (not shown). The surface fastener is provided along the upper side of the pressure adjustment plate 62. The part other than the upper side of the pressure adjustment plate 62 is not connected to the pradhan 31. That is, when the inside of the box becomes negative pressure, the pressure adjustment plate 62 rotates inside the dust collection box 7 around the connection part with the pradhan 31, and is configured to be able to take in outside air into the dust collection box 7. These mechanisms are called the pressure adjustment part 63.

[0035] Openings 65 for attaching the blower device 9 are formed on both sides in the width direction of the outside air intake 61. The blower device 9 is configured to have its blowing nozzle 66 fitted into the opening. As shown in FIG. 4, after the blower device 9 is attached to the opening 65, a blower air outlet 67 with a downward blowing direction is attached to the tip of the blowing nozzle 66.

[0036] The dust collection device 8 is installed outside the rear surface of the wall member 3. An opening 72 is formed in the pradhan 31 at the lower part of the rear surface. The dust collection port 81 of the dust collection device 8 is fitted into the opening 72. The dust collection device 8 is installed outside the rear surface. The pradhan 31 is provided so as to surround the side surface, bottom surface, and top surface of the dust collection device 8. The pradhan is not provided on the rear surface of the dust collection device 8.

[0037] Inside the dust collection box 7, an operation unit 73 for operating the dust collection device 8 and the blower device 9 is attached. The operation unit 73 is installed at an arbitrary position on the wall member 3 inside the dust collection box 7. In this embodiment, it is attached to the wall member 3 on the back side. When the switch is turned on, both the dust collection device 8 and the blower device 9 are set to start operating. When the switch is turned off, the blower device 9 on the air supply side immediately stops, and the dust collection device 8 on the exhaust side is set to stop operating, for example, 10 seconds after the blower device 9 stops. By configuring it in this way, the dust swirling inside the dust collection box 7 can be efficiently collected by the dust collection device 8.

[0038] The assembly, disassembly method, and usage method of the dust collection unit 1 of this embodiment will be described.

[0039] In the disassembled state, each member of the dust collection unit 1 is stored in a storage box or the like, and the storage box is transported to a predetermined position using a trolley.

[0040] At a predetermined position, first, the rod-shaped member 21 and the connecting member 22 are taken out, and the framework part 2 is assembled. At this time, the rod-shaped member 21 and the connecting member 22 are composed of a pipe and a socket, and the framework part 2 can be easily assembled by simply connecting the socket to the end of the pipe.

[0041] The floor member 4 (pladan 41) is arranged on the floor surface at the installation position of the dust collection unit 1, and the framework part 2 is installed on the floor member 4. Next, the wall member 3 (pladan 31) is attached around the framework part 2. As shown in FIG. 6, surface fasteners 32 are provided at the connection points between the wall members 3 connected in the height direction, and the pladan 31s constituting the wall member 3 can be easily assembled by connecting them via the surface fasteners 32.

[0042] In addition, for the corner part, by using the corner member 33 to which the hook-and-loop fastener 34 is attached, the members of the corner part can be easily connected to each other. The corner member 33 is also used to connect the members between the floor member 4 and the wall member 3, and between the wall member 3 and the ceiling member 5. By connecting all the parts, the dust collection box 7 is completed.

[0043] Subsequently, the blower device 9 is installed. The blower nozzle 66 of the blower device 9 is inserted and installed into the opening 65 formed on the back side of the dust collection box 7. The blower device 9 is fixed in position by a method not shown. Inside the dust collection box 7, a blower outlet 67 is attached to the tip of the blower nozzle 66. In this embodiment, two blower devices 9 are installed.

[0044] Subsequently, the dust collection device 8 is installed. The dust collection device 8 is installed on the back side of the dust collection box 7. A plate 31 is installed on the bottom side of the dust collection device 8, and a framework is assembled so as to surround the dust collection device 8. The structure of the framework is the same as that of the framework 2 of the dust collection box 7. After the framework is assembled, the plate 31 is attached to the positions facing the side surface and the top surface of the dust collection box 7. At this time, the back side of the dust collection device 8 is left open without a plate. The dust collection port 81 of the dust collection device 8 is inserted and installed into the opening 72 of the dust collection box 7. By connecting the dust collection port 81 and the dust collection device 8 and fixing the dust collection device 8 at a predetermined position, the installation of the dust collection device 8 is completed.

[0045] Subsequently, the operation unit 73 is installed inside the dust collection box 7. The operation unit 73 is installed at an arbitrary position inside the dust collection box 7. For example, it is attached to the wall member 3 (plate 31) on the back side inside the dust collection box 7. The assembly is completed by connecting the operation unit 73 to the various power supplies of the dust collection device 8 and the blower device 9.

[0046] Next, the usage method of the dust collection unit 1 will be described. After the work, the workers (users) with dust adhering to their work clothes and the like enter the dust collection box 7. After closing the door 71, the worker operates the operation unit 73 to turn on the dust collection device 8 and the blower device 9.

[0047] The dust adhering to the worker is blown by the air flow from the blower device 9 and swirls in the dust collection box 7, and is collected from the dust collection port 81 provided at the lower part of the dust collection box 7 into the dust collection device.

[0048] The dust adhering to the soles of the worker's shoes adheres to the adhesive mat 43 and is removed from the shoes. After a predetermined time has elapsed and the dust removal is completed, turn off the operation unit. At this time, first stop the operation of the blower device 9, and about 10 seconds later, stop the operation of the dust collection device 8. At this time, the pressure adjustment unit 63 prevents the inside of the dust collection box 7 from becoming a negative pressure.

[0049] After the repair work at the relevant location is completed and the dust collection unit 1 is to be moved to another location, the dust collection unit 1 is disassembled. The disassembly of the dust collection unit 1 is performed in the reverse procedure of the above-described assembly process. After disassembling the dust collection unit 1, store each component in a storage box (not shown). After storing each component in the storage box, transport it to the next use location by a trolley. By repeating this, the work can be efficiently performed without leaking dust outside the repair work area.

[0050] The dust collection unit 1 of this embodiment includes a framework portion 2 composed of a rod-shaped member 21 and a connecting member 22 that connects the rod-shaped members 21 to each other, and a dust collection box 7 assembled with a wall member 3, a floor member 4, and a ceiling member 5 disposed so as to cover the framework portion 2, and a dust collection device 8 connected to the dust collection box 7. The dust collection box 7 is configured to be assembled and disassembled. The wall member 3, the floor member 4, and the ceiling member 5 are resin-made pradans (plate-shaped members) 31, 41, 51, and the pradans 31 are detachably connected to each other by surface fasteners 32. By configuring in this way, since the wall member 3, the floor member 4, and the ceiling member 5 that constitute the appearance of the dust collection unit 1 are composed of resin-made pradans 31, 41, 51, and the plate-shaped members 31 are detachably configured by surface fasteners 32, it can be easily assembled and disassembled. Also, since the wall member 3, the floor member 4, and the ceiling member 5 are composed of resin-made pradans 31, 41, 51, the dust collection unit 1 can be lightened and can be easily transported.

[0051] Also, since the rod-shaped member 21 is a resin pipe and the connecting member 22 is a pipe socket, the framework portion 2 can be easily assembled and disassembled, and can be lightened and easily transported.

[0052] Also, since an adhesive mat 43 is provided on the upper surface 42 of the floor member 4, the dust floating in the dust collection box 7 and the dust adhering to the soles of the shoes of the worker (user) can be adhered to the adhesive mat 43. Therefore, when the worker exits from the dust collection box 7, the risk of carrying the dust outside can be reduced.

[0053] Also, since a pressure adjustment portion 63 is provided on the wall member 3, the pressure balance between the inside and the outside of the dust collection box 7 can be maintained via the pressure adjustment portion 63.

[0054] In addition, since the pressure adjustment unit 63 has a pressure adjustment plate 62 that opens toward the inside of the dust collection box 7, when the inside of the dust collection box 7 becomes a negative pressure compared to the outside, the pressure adjustment unit 63 functions to introduce necessary air into the dust collection box 7. Therefore, it is possible to maintain the pressure balance between the inside and the outside of the dust collection box 7 with a simple configuration without leaking the dust inside the dust collection box 7 to the outside.

[0055] In addition, since a blower device 9 for blowing air into the dust collection box 7 is attached to the dust collection box 7, the dust adhering to the operator (user) can be efficiently removed by the blower device 9.

[0056] In addition, since an operation unit 73 for operating the dust collection device 8 and the blower device 9 is provided inside the dust collection box 7, the operator (user) inside the dust collection box 7 can switch the ON / OFF of the dust collection device 8 and the blower device 9 at his / her own timing.

[0057] In addition, since a corner member 33 is provided at the corner of the dust collection box 7, it is possible to prevent dust from leaking from the connection portion between the resin-made plate-like members 31. In addition, the structural strength of the dust collection box 7 can be increased. The corner member 33 is also provided at the corner between the wall member 3 and the floor member 4, and at the corner between the wall member 3 and the ceiling member 5.

[0058] As described above, the embodiment of the dust collection unit 1 according to the present invention has been described. However, the present invention is not limited to the above embodiment, and can be appropriately changed without departing from the gist thereof. For example, in the present embodiment, the configuration of the framework portion 2 has been described in the case where it is composed of a rod-shaped member 21 made of a resin pipe and a connecting member 22 made of a pipe socket. However, the structure of the framework portion 2 may have another structure and material.

[0059] In the present embodiment, the case where the adhesive mat 43 is arranged on the upper surface 42 of the floor member 4 has been described. However, the adhesive mat 43 may not be provided, and another member may be installed.

[0060] In this embodiment, the pressure adjustment unit 63 adopts a structure in which the pressure adjustment plate 62 opens and closes in the dust collection box 7 to adjust the pressure, but another structure may be adopted.

[0061] In this embodiment, the case where the blower device 9 is provided has been described, but another device may be used as long as it can remove the dust of the worker (user).

[0062] In this embodiment, the case where the operation unit 73 for controlling the operation of the dust collection device 8 and the blower device 9 is attached in the dust collection box 7 has been described, but the operation unit 73 may be provided outside the dust collection box 7, or may be configured for automatic operation with a timer or the like.
