On the back side, a net is formed in a waveform, and a pre-filter 19 that can be used without cleaning for a long time is provided detachably.

The body 5 of the air conditioner 1 configured as described above is suspended in the following procedure.

First, the operator has to work with four bolts 30.
The nuts 34, 36, and 37 are screwed with a margin.
The four hanging members 32 are provided with the grooves 3.
The vibration isolator 31 is attached so as to fit into 1a. When the vibration isolator 31 is attached, the suspending device 32 is covered with the vibration isolator 31. Next, the machine body 5 is moved upward so that the bolt 30 passes through each of the four through holes 31b of the vibration-proof material 31, and a bolt (for example, a bolt on the left side in FIG. 1) for performing work later is provided. It is temporarily fixed with the metal fitting 38. Then, U-shaped notches 33a, 35 are formed from above and below the vibration isolator 31.
The bolt 30 is passed through the holders 33 and 35 such that the bolts 30 are inserted into the holders 33 and 35 from the side.
35 is applied to the vibration isolator 31 from above and below. Then, the positional relationship between the through hole 31a of the vibration isolator 31 and the bolt 30 is finely adjusted in the vertical direction and the circumferential direction of the bolt 30, and the nut 3 is adjusted.
4, 36, 37 are tightened toward the vibration isolator 31. The tightening of the nuts 34, 36, and 37 completes the work of fixing the bolt 30 and the suspension tool 32 at one location. And 3 more
When the fixing operation of the bolt 30 and the suspending tool 32 is performed in the same procedure, the suspending operation of the machine body 5 is completed. Then, after the work of suspending the machine body 5 is completed, a refrigerant pipe, a hot water pipe, and a drain hose (not shown) are connected, and the decorative panel 6 is attached to a lower portion of the machine body 5, thereby completing the installation work of the air conditioner 4.

As described above, in the suspension device of this body, 1
The suspension member 32 can be covered from above and below with the two vibration isolator members 31 and the bolts 30 can be inserted into the notches 33a, 35a of the holder members 33, 35 from the side. It is very easy to suspend the aircraft, compared to the conventional aircraft suspension system, in which the vibration material, the suspension of the aircraft, the lower vibration isolator, and the lower retainer are passed through bolts one by one. can do.

Since the through hole 31b of the vibration isolator 31 is formed to be larger than the diameter of the nuts 34, 36, 37, the bolts 30 are screwed into the bolts 30, 36, 37. Can be passed through the through-hole 30b, so that the work procedure is not limited and the work becomes easier. In addition, since there is a margin in the circumferential direction of the bolt 30,
And the position of the hanging tool 32 can be finely adjusted. Further, the bolt 30 is fixed to the suspending device 32 because the bolt 30 is passed through the through hole 32a of the suspending device 32. It is prevented that the fixing of the hanging member 32 with the hanging member 32 comes off.

Further, the vibration isolator 31 is fitted into the suspender 32, and the holders 33 and 35 are engaged with the vibration isolator, so that the suspender 32, the vibration isolator 31 and the retainer are fitted. 33,
35 can be moved in the vertical and horizontal directions as one stiffness, so that the fine adjustment of the positions of the suspenders 32 and the bolts 30 can be easily performed.

FIG. 6 shows an example in which the airframe is suspended in another house by the airframe suspension apparatus of the present invention. The figure shows a house built by a construction method called a framed wall construction method, for example, 40 is a floor plate on the second floor, 41 is a ceiling plate on the first floor, 42 is a support plate extending between the ceiling plate and the floor plate 40, 43 is a floor plate. An L-shaped fitting for attachment, 44 is a wood screw for attaching the L-shaped fitting to the support plate 42, 45 is a through bolt shown in a circle, and the L-shaped fitting 4
3 is attached to the support plate 42, and either this through bolt or wood screw 44 is used. 46 is a bolt arranged in the ceiling, and 47 is a nut for fixing the bolt.

In the hanging device of the airframe, the airframe can be hung in a house as shown in FIG. 6 by using the L-shaped bracket 43.

[0023]

According to the present invention, there is provided a suspender on the outer wall of the body, into which a bolt suspended from the ceiling can be inserted, and the suspension of the body being held by a pair of nuts screwed to the bolt. In the device, a vibration isolator for covering the hanging device and a U-shaped notch into which a bolt can be inserted are formed from the center to the edge, and the side surface of the vibration isolator is located above and below the vibration isolator. And two holding members provided with a support portion that abuts the holding member. The vibration damping material covering the hanging member into which the bolt is inserted is sandwiched from above and below by the two holding members, and the vibration damping member is held by the pair of nuts. Since the device is fixed by being clamped via the holding tool, the hanging tool can be covered with one anti-vibration material, and the bolt can be inserted by inserting the bolt into the U-shaped notch of the holding tool from the side. Holds between the inserted vibration isolator and nut Since it is possible to interpose a, it is possible to very easily perform the hanging work as compared with the conventional one have been sequentially through every single part of the bolt. In addition, when the holder is positioned on the lower surface side of the vibration isolator, the support of the holder abuts against the side surface of the vibration isolator. Even if the body is moved, the holding portion is unlikely to come off from the vibration isolating material, and the hanging operation can be easily performed.
