DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings of the embodiments.

FIG. 1 shows an embodiment of a wall-mounted air conditioner in which an indoor unit main body and a back plate are combined. Reference numeral 1 denotes a combination of a back plate 2 fixed to a wall surface serving as a metal plate and a housing type indoor unit body 3. An indoor unit to be a wall-mounted air conditioner. This back plate 2 is provided with hanging projections 4 slightly bent inward on both sides of an upper edge portion. The receiving groove 5 formed on both sides of the unit is hung, and the lower end 2a of one side of the back plate 2 (the side of the indoor unit main body equipped with a motor or the like) has an L-shaped hooking hook 6 at the upper end. The lower end of the synthetic resin support 7 having a predetermined width and having the above-mentioned shape is pivotally mounted. This synthetic resin inclined support 7
Is raised on the back plate 1 surface during non-working such as refrigerant pipe connection work, and a locking piece 9 which is nailed up from the back plate 2 is inserted into a locking hole 8 formed in an upper portion by an elastic fitting, and is also formed in a lower portion. A pair of vertical locking pieces 11 that are nailed upright from the back plate 2 in the provided long slot 10
And a storage structure that fits between them. Further, a U-shaped inclined fixing portion 12 is formed at the lower end 3a of the rear surface of the indoor unit main body 3 which is an installation-facing surface of the inclined support member 7, and a locking claw 13 provided on an upper piece 12a of the inclined fixing portion 12 is formed. Is fitted into the locking hole 8 of the inclined support member 7, and the hooked hook portion 6 is engaged with the inclined fixed portion 12. It becomes the gap means 14. In the drawing, reference numeral 15 denotes a decorative plate mounted on the front of the indoor unit main body 3, 16 denotes a refrigerant pipe, 17 denotes a drain hose, 1
Reference numeral 8 denotes electric wiring, and 19 denotes a refrigerant pipe on the outdoor unit side.

Next, the operation will be described. When the wall-mounted indoor unit 1 is installed on the wall, first, the back plate 2 is mounted.
Is fixed to a wall surface (not shown) in advance with an appropriate peg or the like. Thereafter, the receiving groove 5 at the upper edge of the rear surface of the indoor unit body 3 is hooked on the hanging projection 4 at the upper edge of the back plate 2 to obtain the indoor unit 1.

Here, for example, when a predetermined pipe connection operation is performed between the refrigerant pipe 19 introduced into the back plate 2 guided from the outdoor unit side and the refrigerant pipe 16 on the indoor unit main body 3 side, usually from below the indoor unit 1. It is what you do. That is, this is performed by forming a gap A for piping work in the lower part of the indoor unit 1. First, the indoor unit body 3 suspended from the upper end of the fixed back plate 2 is inserted into the receiving groove 5 at the upper edge.
If it is inclined at an appropriate angle so that the lower side is opened toward the front side with the fulcrum as a fulcrum, a piping work gap A is formed at the bottom (downward). In order to maintain the gap A, the synthetic resin inclined support 7 erected on the back plate 2 and in the housed state is fixed to the locking piece 9 and the vertical locking piece 11.
If it is pulled down with the pivot at the lower end as a fulcrum against the gripping of the lower end of the indoor unit main body 3, the hook 6 formed at the tip (upper end) of the inclined support 7 is turned. The hooking hook 6 of the slanting support 7 stops at the frame corner 12b serving as the slanting end, and the hook provided on the base of the hooking hook 6 when the hooking hook 6 is inserted so as to be inserted into the L-shaped slant fixing part 12. The locking claw 13 of the inclined fixing portion 12 is fitted into the hole 8 to engage with the claw.

That is, by simply pulling down the synthetic resin inclined support 7 of the back plate 2 with the indoor unit main body 3 appropriately tilted toward the front side, the hooking hook portion 6 at the tip is moved to the indoor unit main body 3.
Of the indoor unit body 3 and the back plate 2 to form a gap A for piping work.

A predetermined plumbing operation may be performed using the plumbing operation gap A having the downward opening configured as described above. Moreover, since the inclined support 7 is inserted into the frame corner 12b of the inclined fixing portion 12 on the back side of the indoor unit main body 3, there is no danger of falling down easily, and the inclined support 7 is located at a position where its existence is confirmed. Therefore, workability is not hindered.

After the installation work of the piping and the like is completed,
Conversely, if the indoor unit body 3 is first opened slightly, the hooking hook portion 6 of the inclined support member 7 which is in contact with the frame corner 12b and stops is loosened, and the inclined fixing portion 1 is opened.
When the inclined support 7 is turned upright on the back plate 2 side, the long groove hole 10 is inserted between the pair of vertical locking pieces 11 of the back plate 2 which are set up by the nails. At the same time, the locking pieces 9 are inserted into the locking holes 8 at the upper end, and are stored upright.

Therefore, when the support bar (tilt support member 7) is in a folded state, the indoor unit body 3 that has been tilted and expanded is returned to the back plate 2 side, and is fitted with a predetermined stopper (not shown). If stopped, it becomes an integrated indoor unit 1.

[0015]

As described above, the air conditioner of the present invention is constructed such that the indoor unit body and the back plate are assembled so that the indoor unit is suspended above the back plate, and the back plate is foldable (standing upright). With the provision of the fittings, in order to form the working gap required for piping work, it is only necessary to use the support rod between the indoor unit bodies tilted by pulling the support tool toward the front, and a simple and reliable piping work gap Get. In addition, since the support tool once pulled down is engaged with the fixture on the unit side, there is no possibility that the support tool will come off, and the piping work or the like can be performed by one worker. In addition, the piping work gap has an effect that the gap can be used for inspection at the time of maintenance after the installation work.
