Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for a blowout panel that supplies conditioned air from a ceiling surface.

[Conventional technology]

In clean rooms used for semiconductor manufacturing, operating rooms, etc., a plurality of blowout panels are provided at the bottom of a ceiling plate, and purified conditioned air is supplied from these blowout panels.

To explain this with reference to FIGS. 4 to 6, the unit case 1 of the air passage installed in the ceiling.
is arranged such that the edge 1a of the outlet portion protrudes downward from the opening 2a formed in the ceiling plate 2, and this lower edge 1
The edge of the upper opening of the air outlet panel 3 is connected to a, and the air outlet panel 3 is suspended and supported on the lower surface of the ceiling board 2.

The blowout panel 3 is made of punched metal with a large number of small circular holes 3a formed into an inverted truncated pyramid shape, and a mounting flange 4 is fixed on the upper outer periphery of the inclined surface plate 3b, and the four corners of the flange 4 are It is attached to the edge 1a of the unit case 1 with bolts 5, and this blow-off panel 3 is attached and detached every time the air filter 6 in the unit case 1 is replaced.

[Problem that the invention attempts to solve]

However, in clean rooms where a large number of blowout panels are arranged, ranging from tens to over a hundred, four bolts are required to install one panel, so bolting alone takes a lot of effort and time. On the other hand, on the lower edge of the unit case, it was necessary to form a female threaded hole for screwing the bolt or to secure the nut, and there was a desire to improve the installation.

Therefore, an object of the present invention is to provide a mounting structure for a blow-off panel that can be easily attached and detached in a short period of time.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention makes the outlet of the air passage arranged in the ceiling face the opening of the ceiling plate, connects the edge of the upper surface opening to the outlet, and connects the edge of the upper surface opening to the ceiling plate. In the mounting structure for an air conditioning outlet panel that is suspended and supported on the lower surface of the air conditioner, the upper opening of the outlet panel is formed larger than the outlet of the air supply passage, and the inner side of the two edges facing the upper opening is provided with a latch piece that protrudes in an L-shape with its tip facing downward, and on the other hand, two of the air supply passages facing the outlet part are provided.
The device is characterized in that receiving pieces projecting in an L-shape with their tips facing upward are provided on the outside of the two side plates, and the latching pieces are hooked onto the receiving pieces to attach the blow-off panel.

[Effect]

According to the above configuration, the blowout panel can be easily attached and detached in a short time without using fasteners such as bolts.

〔Example〕

An embodiment of the present invention will now be described with reference to Figs.

A plurality of blowout panels 10 are provided at the bottom of the ceiling board 2.
However, a unit case 1 is provided in the ceiling that communicates with each of these blowout panels 10, and the conditioned air generated by the air conditioner enters the unit case 1 through the supply duct 11, and is sent to the unit case 1. After being muffled in a chamber 12 inside and further purified by a high-performance air filter 6, it is sent to a clean room 13 from a blowout panel 10.

The unit case 1 has a cap 14 on the rim of the opening.
is provided surrounding the base, and the base 14 is arranged to protrude from the opening 2a of the ceiling plate 2 into the clean room 13,
The edge 14a folded upward is brought into contact with the lower surface of the ceiling plate 2 to prevent conditioned air from entering the ceiling.

Each blowout panel 10 has a small circular blowout hole 15.
a lower surface plate 16a having an elongated outlet hole 17;
The edge 16 of the inclined surface plate 16b, which is an inverted truncated pyramid shape and has an opening on the upper surface.
c is formed larger than the base 14 of the unit case 1, and the blowout panel 10 has an edge 16.
Attach the latch piece 18 extending from the unit case 1 to the unit case 1.
It is suspended and supported by a receiving piece 19 fixedly attached to the base 14 of.

The above-mentioned latching piece 18 is attached to the web 1 that protrudes inwardly.
The rim 18b is folded downward to form an L-shape at the tip of the rim 8a, and the two edges 16c, 1 facing the upper surface opening are provided.
Two receiving pieces 19 are provided on the inside of each rim 6c, and one rim 19a is fixed to the outer surface 14b of the base 14 with the opening of the groove-shaped member facing upward, and the web 19b and the other are fixed to each other. The rim 19c is arranged in a protruding L-shape, and like the latching piece 18, two receiving pieces 19 are provided on each of the two opposing outer surfaces 14b, 14b of the base 14.

Note that 20 is a bearing bracket fixed to the inner plate 14c of the base 14, 21 is a cam member removably disposed at the outlet of the unit case 1, and the air filter 6 connects the cam shaft 22 to the bearing bracket 20.
The unit case 1 is connected to the cam member 21 which is supported by the
supported within.

The present embodiment is constructed as described above, and the blowout panel 10 has the hooking pieces 18, 1 on one edge 16c.
8 on one of the receiving pieces 19, 19, and while lifting the opposite edge 16c slightly, attach the blowout panel 10 to the rims 18b, 1 of both pieces 18, 19.
When the panel 9c slides in the latching direction until it abuts, the latching pieces 18, 18 of the other edge 16c enter into the other receiving pieces 19, 19 and are latched, and the blow-out panel 10 is slightly returned to the unit case 1. It is installed at the bottom center of the outlet section of the

Furthermore, when replacing the air filter 6, the blow-off panel 10 is removed in the reverse order of the above-mentioned installation, and is pulled out from the cam bracket 21 which is supported by the bearing bracket 20, and the air filter 6 is removed downward.

As described above, in this embodiment, the blowout panel can be easily attached or removed by simply hooking the hooking piece to the receiving piece of the unit case.
This eliminates the need for bolts and bolt fastening work, significantly shortening work time, and is particularly suitable for use in clean rooms where a large number of blowout panels are installed, ranging from dozens to over 100. .

[Effect of idea]

As explained above, the present invention has the top opening of the blowout panel larger than the outlet of the air supply passage, and the tip of the blowout panel is directed downward inside the two edges of the blowout panel facing the top opening. Attach the latch piece that protrudes in an L shape to the two parts of the air supply passage facing the outlet.
On the outside of the two side plates, we provided receiving pieces that protruded in an L-shape with the tips pointing upwards, and attached the latching pieces to the receiving pieces to attach the blowout panel. Work that depends on posture can be freed, and the blowout panel can be easily attached and detached with a small number of personnel, and the working time can be significantly shortened.
