The outlet 5g is provided on the side 13a side from the center in the width direction of the side 13c, with the central axis of the outlet 5g offset from the center.

Outlets 5f and 5g are evenly spaced across the width of side 13c.

In addition, the outlets 5f and 5g are provided with their central axes shifted from the center of the side surface 13c toward the top surface 14 so that the central axes of the outlets 5a and 5f and 5g are on the same plane.

The branch duct connection parts 6f, 6g each have a removable opening 10f, 10g, a flow rate adjustment part 7f, 7g, and fixing parts 8f, 8g for fixing the flow rate adjustment part 7f, 7g, and the flow rate adjustment part 7f, 7g is fixed to the fixing parts 8f, 8g with screws.

Flow rate adjustment units 7f and 7g will be described later.

The detachable openings 10f, 10g have a rectangular shape and are openings for attaching and detaching the flow rate adjustment units 7f, 7g. The detachable openings 10f, 10g are openings opened on the control unit 9 side of the branch duct connection units 6f, 6g, and are provided so that the central axis of the detachable openings 10f, 10g coincides with the central axis of the outlets 5f, 5g in the width direction. The detachable openings 10f, 10g are provided on the bottom surface 15 side of the body 1 near the outlets 5f, 5g. In this embodiment, the detachable openings 10f, 10g are provided on the branch duct connection units 6f, 6g, but may be provided on the body 1 itself, for example. The detachable openings 10f, 10g are provided so that the central axis of the detachable openings 10f, 10g coincides with the central axis of the outlets 5f, 5g in the width direction. The detachable openings 10f, 10g are also provided downstream of the outlet in the branch duct connection direction. In addition, the detachable openings 10f and 10g are provided so that the center points of the detachable openings 10f and 10g coincide with the center in the branch duct connection direction.

Side 13d has outlet 5b and outlet 5c.

Outlets 5b and 5c have a cylindrical shape with the same diameter as outlet 5a, and are provided with branch duct connectors 6b and 6c that protrude, for example, to the outside of body 1. Outlets 5b and 5c are openings for allowing air inside body 1 to flow out to the rooms connected via branch duct connectors 6b and 6c and the duct.

The outlet 5b is provided on the side 13a side from the center in the width direction of the side 13d, with the central axis of the outlet 5b offset from the center.

The outlet 5c is provided on the side 13b side from the center in the width direction of the side 13d, with the central axis of the outlet 5c offset from the center.

Outlets 5b and 5c are evenly spaced across the width of side 13d.

In addition, the outlets 5b and 5c are provided with their central axes shifted from the center of the side surface 13d toward the top surface 14 so that the central axes of the outlet 5a and the outlets 5b and 5c are on the same plane.

The branch duct connection parts 6b, 6c each have a removable opening 10b, 10c, a flow rate adjustment part 7b, 7c, and fixing parts 8b, 8c for fixing the flow rate adjustment parts 7b, 7c, and the flow rate adjustment parts 7b, 7c are fixed to the fixing parts 8b, 8c with screws.

Flow rate adjustment units 7b and 7c will be described later.

The detachable openings 10b, 10c have a rectangular shape and are openings for attaching and detaching the flow rate adjustment units 7b, 7c. The detachable openings 10b, 10c are provided on the bottom surface 15 side of the body 1 near the outlets 5b, 5c. In this embodiment, the detachable openings 10b, 10c are provided on the branch duct connection parts 6b, 6c, but may be provided on the body 1 itself, for example. The detachable openings 10b, 10c are provided so that the central axis of the detachable openings 10b, 10c coincides with the central axis of the outlets 5b, 5c in the width direction. The detachable openings 10b, 10c are also provided downstream of the outlets in the branch duct connection direction.

The detachable openings 10b, 10c are openings opened on the control unit 9 side of the branch duct connection parts 6b, 6c, and are provided so that the central axis of the detachable opening 10b coincides with the central axis of the outlets 5b, 5c in the width direction. In addition, the detachable openings 10b, 10c are provided so that the central points of the detachable openings 10b, 10c coincide with the center in the branch duct connection direction.

The above configuration ensures that the central axes of outlets 5a, 5b, 5c, 5d, 5e, 5f, and 5g are located on the same plane.

Top surface 14 is adjacent to side surfaces 13a, 13b, 13c, and 13d.

The bottom surface 15 is adjacent to the side surfaces 13a, 13b, 13c and 13d, and faces the top surface 14.

The up-down relationship of the top surface 14 and the bottom surface 15 does not necessarily have to match the names. In other words, when the chamber device 100 is installed, there is no problem if the top surface 14 is positioned vertically downward and the bottom surface 15 is positioned vertically upward.

On the top surface 14, the branch duct connection part 6b, the branch duct connection part 6c, the branch duct connection part 6d and the branch duct connection part 6e are provided with the fixing bracket 12a, the fixing bracket 12b, the fixing bracket 12c and the fixing bracket 12d, respectively.

The fixing brackets 12 (12a to 12d) have an L-shaped cross section and two nearly perpendicular flat surfaces, one of which forms a fixed flat surface that is fixed by a bolt when installed and has a U-shaped opening, or U-cut, through which the bolt passes.

The fixing bracket 12a has a fixing plane that is flush with the top surface 14, protrudes toward the outer periphery, and the other surface is arranged to contact the side surface 13a of the branch duct connection portion 6b.

The fixing bracket 12b has a fixing plane that is flush with the top surface 14, protrudes toward the outer periphery, and the other surface is arranged to contact the side surface 13b of the branch duct connection portion 6c.

The fixing bracket 12c has a fixing plane that is flush with the top surface 14, protrudes toward the outer periphery, and the other surface is arranged to contact the side surface 13b of the branch duct connection portion 6f.

The fixing bracket 12d has a fixing plane that is flush with the top surface 14, protrudes toward the outer periphery, and the other surface is arranged to contact the side surface 13a of the branch duct connection portion 6g.

The bottom surface 15 has a fixing portion 11 for attaching the control unit 9.

The fixed part 11 is U-shaped, has a flat surface facing away from the body 1 in the vertical direction, and is open toward the inlet 3. The fixed part 11 is provided on the side 13b side from the center in the main duct connection direction (up-down direction in FIG. 3) of the bottom surface 15, with the center of the fixed part 11 shifted, and is provided in the center in the direction perpendicular to the main duct connection direction (left-right direction in FIG. 3).

When installing the chamber device 100, it is fixed to the ceiling or inter-floor space by fixing brackets 12a, 12b, 12c, and 12d.

The control unit 9 is a rectangular parallelepiped, and has a hollow rectangular shape with an openable lid on the surface opposite to the plane fixed to the fixing unit 11, that is, on the underside opposite to the bottom surface 15. The control unit 9 is attached close to the side surface 13b opposite to the side surface 13a where the inlet 3 and the main duct connection unit 4 are located. Therefore, if the diameter of the inlet 3 is larger than the diameter of the outlet 5, a tapered portion inclined from the inlet 3 toward the outlets 5d and 5e can be provided on the side surface 13a side of the bottom surface 15. The side surface of the control unit 9 is arranged parallel to the side surface 13 of the body 1, and the control unit 9 has a shape in which the fixing direction relative to the bottom surface 15 of the body 1 is uniquely determined. In other words, although the control unit 9 is detachable, its orientation relative to the body 1 is unique, and the flow rate adjustment unit 7 and each connector of the control unit 9 can be connected in close proximity to each other for the connection described below.

Next, the flow rate adjustment unit 7 will be described with reference to FIG. 2.

The flow rate adjustment unit 7 includes an electrical component unit 17 and an opening/closing mechanism unit 16.

The electrical equipment section 17 is hollow and rectangular, has a detachable cover facing the opening/closing mechanism section 16, and has an electric motor 21 disposed inside.

In addition, the electrical equipment section 17 has protruding rectangular sealing ribs 23 on both widthwise sides.

The opening and closing mechanism 16 includes a rotating shaft 18, a wind stopper plate 19, and a holding part 20.

The rotating shaft 18 is cylindrical and connected to the rotating shaft of the electric motor 21, transmitting the rotational force of the electric motor 21 to the wind stopper plate 19.

The wind stopper plate 19 is a circular plate that can be rotated by the rotation of the rotation shaft 18 from 0 degrees, which is parallel to the holding part 20, to 90 degrees, which is perpendicular to the holding part 20.

The holding part 20 is a part for holding the wind stop plate 19, and is located on the outer periphery of the wind stop plate 19, surrounding the wind stop plate 19 and having a plate-like U-shaped outer shape. In other words, the holding part 20 is U-shaped with an arc-shaped frame on the opposite side of the electrical equipment part 17 and two parallel bars on the electrical equipment part 17 side.

The flow rate adjustment units 7 are inserted into the detachable openings 10 from the opening/closing mechanism unit 16 side while aligning the rotation axis 18 with the central axis of the corresponding detachable opening 10. The inserted flow rate adjustment units 7 are fixed in a state in which the electrical equipment unit 17 protrudes from the branch duct connection unit 6, that is, in a state in which it is exposed to the outside of the body 1.

The flow rate adjustment section 7 inserted into the branch duct connection section 6 prevents air leakage from the detachable opening 10 by the sealing rib 23 coming into contact with the periphery of the detachable opening 10.

The electrical equipment unit 17 is arranged so that its bottom surface is vertically downward and its top surface is vertically upward, and furthermore, when viewed from the front from the protruding surface of the outlet 5 corresponding to each electrical equipment unit 17, the right side is provided with a flow rate adjustment unit side connector 24 to which wiring from the electric motor 21 is connected.

The flow rate adjustment unit side connector 24 has the same shape as the control unit side connector 25 provided on the side of the control unit 9. The wiring 26 has connectors at both ends that match the flow rate adjustment unit side connector 24 and the control unit side connector 25, and is electrically connected by connecting one end to the flow rate adjustment unit side connector 24 and the other end to the control unit side connector 25. Here, the control unit side connector 25 corresponds to the wiring connection part in the control unit 9.

In this embodiment, connectors are provided on the side of the electrical equipment unit 17 and on the control unit 9, making the wiring detachable. However, the flow rate adjustment unit side connector 24 may be provided on only one of the electrical equipment unit 17 or the control unit 9, making the wiring detachable.

When the electric motor 21 rotates at a specified angle in response to an instruction from the control unit 9, the wind stopper plate 19 connected to the electric motor 21 via the rotating shaft 18 rotates, and the amount of air passing through the outlet 5 can be adjusted.

Next, the control unit 9, flow rate adjustment unit 7, and inspection hatch 22 will be explained with reference to FIG. 3.

The chamber device 100 is installed in the interfloor space by means of a hanging bolt (not shown) passed through the fixing bracket 12, with the control unit 9 and electrical equipment unit 17 facing vertically downward.

A rectangular inspection hatch 22 is located on the ceiling directly below the placement chamber device 100.

The control unit 9 and all flow rate adjustment units 7 of the chamber device 100 are located inside the inspection hatch 22.

In other words, the control unit 9 and all of the flow rate adjustment units 7 are located inside the plane projection of the opening of the inspection hatch 22 onto the chamber device 100. Therefore, when inspecting or replacing the flow rate adjustment units 7, an operator who opens the inspection hatch 22 can directly and vertically view the control unit 9 and all of the flow rate adjustment units 7 from the inspection hatch 22.

In addition, since the control unit 9 and the multiple flow rate adjustment units 7 can all be attached and detached in the same direction from the bottom surface 15, the control unit 9 and the flow rate adjustment units 7 can be removed by removing the screws that secure the flow rate adjustment units 7 of the chamber device 100 to the fixed parts 8 and the wiring that is connected to the flow rate adjustment units 7 via a connector. In other words, it is possible to easily inspect or replace the control unit 9 or the flow rate adjustment units 7 by removing them without removing or moving the chamber device 100. In addition, since the lower part of the control unit 9 can be opened and closed, maintenance and other procedures can be performed without having to remove it.

In addition, if the inspection hatch 22 cannot be placed on the ceiling directly below where the chamber apparatus 100 is placed, the chamber apparatus 100 can be installed in a floor-standing state by inverting it upside down and bolting the fixing brackets 12 to wood or the like in the inter-floor space. In this case, by placing the inspection hatch 22 on the floor directly above the chamber apparatus 100, the control unit 9 and all flow rate adjustment units 7 can be directly and visually observed from the vertical direction through the opening of the inspection hatch 22. By removing the screws that secure the flow rate adjustment units 7 of the chamber apparatus 100 to the fixed parts 8 and the connection wires that are connected to the flow rate adjustment units 7 via connectors, the flow rate adjustment units 7 can be removed from the chamber apparatus 100 for inspection or replacement, which can alleviate the constraints on the installation location of the chamber apparatus 100.

Next, the flow rate adjustment unit side connector 24, the control unit side connector 25, and the wiring 26 will be described with reference to FIG. 4.

The control unit side connectors 25 (control unit side connectors 25a to 25g) have a convex shape, and the control unit side connectors 25a to 25d are provided on the side surface 13d of the control unit 9 from which the outlet 5b or 5c protrudes. In addition, the control unit side connectors 25a to 25g are provided with equal spaces between adjacent control unit side connectors 25 in the width direction.

On the other hand, the flow rate control unit side connectors 24e to 24g are provided on the side surface 13c of the control unit 9 from which the outlet 5f or 5g protrudes. Similarly, the control unit side connectors 25e to 25g are also provided with equal spaces between adjacent control unit side connectors 25 in the width direction.

The positional relationship between the flow rate adjustment unit side connector 24 and the control unit side connector 25 is such that the pairs that connect to each other are aligned in the clockwise direction starting from the flow rate adjustment unit side connector 24a and the control unit side connector 25a. In other words, the positions of the flow rate adjustment unit 7 provided near the side surface 13 of the body 1 and the control unit side connector 25 (wiring connection portion) provided on the side surface of the control unit 9 are aligned in the circumferential direction when viewed from the bottom.

The wiring 26 has a fixed length, and the body length of each line is the same. The wiring 26 connects the flow control unit side connector 24 and the control unit side connector 25 to transmit signals generated by the control unit 9 to the electrical equipment unit 17 of the flow control unit 7.

The control unit side connector 25 is provided on two sides of the control unit 9, the side from which the outlet 5b or 5c protrudes and the side from which the outlet 5f or 5g protrudes, that is, the sides that face each other. Therefore, the main body length of the wiring 26 connecting the flow rate adjustment unit side connector 24 and the control unit side connector 25 can be made as short as possible compared to when the control unit side connector is located on only one side of the control unit 9.

As a result, it is possible to provide a chamber device that reduces the labor required for inspecting and replacing the flow rate adjustment unit, allows for easy maintenance, and increases the freedom of installation location.

In this embodiment, the inlet 3 and the outlet 5a are provided on the side surface 13a, so the inlet 3 is located on the side surface 13c and the outlet 5a is located on the side surface 13d. However, the side surface 13a may be provided with only the inlet 3, and the inlet 3 may be located in the center of the side surface 13a.

In addition, in this embodiment, the number of outlets 5 is seven, but if the number is two or more, the chamber device 100 will function by branching the air flowing in from the inlet 3 into multiple branches.

In addition, in this embodiment, the air volume is changed by rotating the circular wind stopper plate 19 connected to the electric motor 21 via the rotating shaft 18, but any other method, such as a sliding structure, may be used to change the air passage area and change the air volume.

The chamber device according to the present invention has a flow rate adjustment unit that can be directly accessed from an inspection hatch and is removable, allowing for easy maintenance. Similarly, the control unit can be directly accessed from an inspection hatch for easy maintenance. The chamber device can be positioned with the bottom surface facing vertically upwards and the top surface facing vertically downwards.
