Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ceiling-mounted clean unit that can form a clean area in a part of a room.

[Prior Art] Conventionally, as a clean room, for example, a one-sided laminar flow type (full-scale ceiling blowing type) shown in Fig. 10 or a 11-type clean room
The conventional method (partial blowing method) shown in the figure is known.

In the full-surface laminar flow type, as shown in Fig. 10, a ceiling chamber Tc is provided in the upper part of the clean room R, and a HEPA filter (High Efficiency
The ceiling chamber Tc and the clean room R are connected by a blower F and an air duct Ds installed outside the room, and the blower F causes the circulating air a to pass through the filter H, thereby cleaning the circulating air a. At the same time, a descending laminar flow is blown into the clean room R.

Also, in the conventional method, as shown in Figure 11,
A filter chamber Hc with filters H provided on the bottom surface at required locations on a ceiling plate Tb stretched over the top of the clean room R.
A plurality of air supply ducts Ds are installed, each branching into an air supply duct Ds, and the air aF, which is connected to the air supply duct DS, is used to partially lower the clean air a with increased cleanliness into the clean room R. It's gushing out.

[Problems to be solved by the invention] However, conventional air purification means in clean rooms are
With the above configuration, it was necessary to provide an air blower F and an air supply duct DS outdoors in order to guide the circulating air a. Therefore, duct work will be required. Also, for example, in the conventional method, if the layout of the room is changed or the installation position of the equipment is changed,
Duct work had to be done each time.

In addition, in the one-sided laminar flow system, the clean air flow is uniform and laminar, but it requires a ceiling chamber and a filter is installed throughout the entire surface, which not only lowers the indoor ceiling but also reduces material and facility construction costs. The problem is that it is expensive.

Furthermore, in the conventional method, the filter part of the filter chamber protrudes from the bottom surface of the ceiling board, and
Since the clean air is blown out in only one direction downward, a vortex is generated and stagnates on the side of the protruding part, and this part does not become a circulating air flow, so there is a drawback that dust cannot be discharged quickly.

The present invention has been made to solve these conventional problems, and its purpose is to provide a ceiling-mounted clean unit that can form a clean room without using an air duct.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

1 to 5 show a ceiling-mounted clean unit according to an embodiment of the present invention, and in the figures, 1 represents a suction device having a semicircular cross section.

This suction device 1 includes a punching plate 2 having a substantially semicircular cross section with a large number of suction ports 3 bored in a wall surface, and a punching plate 2 having a substantially semicircular cross section.
Similarly, it has a substantially semicircular cross section, is wider than the punching plate 2, and is surrounded by a plate body 4 connected to the punching plate 2, a side wall 5 attached to the opening of the punching plate 2, and the plate body 4. The air blower 6 is installed in a closed area.

As the blower 6, an axial fan such as a sirocco fan is used, and the suction port 6a is directed toward the upper opening, and the blowout port 6b is directed toward the side opposite to the punching plate 2. Incidentally, a pre-filter for removing coarse dust may be attached to the inside of the punching plate 2. Note that 7 is a motor of the blower 6.

On the outlet 6b side of the blower 6 in this suction device 1,
A filter device 10 having the same cross-sectional shape as the suction device is mounted flush.

This filter device 10 includes a HE P that filters the air sucked into the suction device 1 and blows clean air indoors.
An A filter 11 is arranged. This HEPA filter 11 has an expanded metal 12 attached to the front side and a punched metal 13 attached to the inside so that the cross-sectional shape is approximately semicircular. As this HEPA filter 11, a clean room air filter without a separator is used. I-shaped support fittings 14 are attached at predetermined intervals within the HEPA filter 11 to maintain the filter shape. Further, a side wall 15 having a substantially semicircular cross-sectional shape is attached to the end of the HEPA filter 11 in the filter device 10.

Further, a top plate 20 is attached to the ceiling side openings of the suction device 1 and the filter device 10. In this example, a blower 6 is attached to this top plate 20.

As a result, the suction device 1 and the filter device 10 are configured such that when the blower 6 is driven, air is sucked through the suction port 3 of the suction device 1, the air is sucked through the suction port 6a of the blower 6, and the air is sucked from the air outlet 6b. H in the filter device 10
An air passage can be formed through which air can be discharged to the EPA filter 11 and blown out through the HEPA filter 11.

Further, two mounting members 21 such as angle members are attached to the upper part of the top plate 20, so that the suction device l, the filter device 10, and the top plate 20 can be hung together from the ceiling or directly attached. It's Nishide.

Next, the operation of this embodiment configured in this manner will be explained.

For example, as shown in FIG. 5, three ceiling-mounted clean units (T) according to this embodiment are each attached to the ceiling of a room (not shown) via attachment members 21. This completes the installation of the ceiling-mounted clean unit T according to this embodiment.

When the blower 6 of this ceiling-mounted clean unit T is driven, the air blown out by the air conditioner in this room is sucked in from the suction port 3 of the suction device 1, and then the air is sucked into the suction port 6a of the blower 6. The air is blown out from the outlet 6b to the filter device 10 through the air outlet 6b. The air blown into the filter device IO passes through the HEPA filter 11 located below, and is blown out toward the floor in a range of about 180' by the curved surface formed by the HEPA filter 11.

As described above, according to this embodiment, the air blown out from the air conditioner in the room is taken in and the air is blown out evenly into the room from the semi-circular HEPA filter. A clean area can be created.

Although we have explained the case where the room is air-conditioned, it is not possible to make the area where this ceiling-mounted clean unit T is installed function as a clean area even if it is installed in a general room that is not air-conditioned. be.

6 and 7 show a modification of the ceiling-mounted clean unit T according to the present invention, in which the air outlet 6b of the blower 6 is
It is long enough to reach the top of the filter device 10.

This makes it possible to provide a rectifying effect that stabilizes the air blowing from the blower 6.

8 and 9 show a second embodiment of the ceiling-mounted clean unit l-T according to the present invention, in which blowers 6 are provided on both sides of the filter device IO.

According to this, it becomes possible to obtain a larger amount of air.

In addition, in FIG. 5, a ceiling-mounted clean unit according to the present invention is shown.
Although the case where -Ts are provided in series has been described, it is also possible to use them alone.

[Effect of idea]

As described above, the ceiling-mounted clean unit described in claims 1 to 4 can be easily installed in any room having a ceiling to which the mounting member can be attached, and can be used as a driving source for the ceiling-mounted clean unit. All you have to do is connect the blower to the power source. Therefore, it is no longer necessary to provide an air duct and a blower outside the room as in the conventional system, and the associated duct work and the like are no longer necessary. Moreover, since it is easy to attach and detach by attaching and detaching the attaching member, even if there is a change in equipment or a change in layout, it can be easily accommodated.

In addition, after installation, just drive the built-in blower.
Clean air is blown out from the IfEPA filter, which has a substantially semicircular cross section, in a range of approximately 1F30°, making it possible to create a clean area. That is, it becomes possible to easily convert an existing room into a clean room.

Furthermore, they can be freely arranged depending on the use and purpose. Furthermore, by changing the arrangement density, the cleanliness can be adjusted.

According to the ceiling-mounted clean unit described in claim 4, since the width of the HEPA filter can be made small, it is possible to make the unit compact.
