[Problems to be Solved by the Invention]

Since the conventional air conditioner is configured as described above,
When lifting the lower part of the air conditioner main body during piping connection work, for example, if you lift one of the left and right sides with one hand, upward force is applied and one of the engaging recesses disengages from the support arm of the installation plate. There is a problem that the air conditioner may fall, and if the air conditioner main body is tilted more than a predetermined angle, the engaging recess will come off the support arm of the installation plate, and the air conditioner will also drop. There was a problem.

The present invention has been made to solve the above problems, and an object thereof is to obtain an air conditioner mounting device that can prevent the air conditioner from falling and is easy to install.

[Means for Solving the Problems]

In the air conditioner mounting device according to the present invention, a mounting arm provided on a mounting plate mounted on a wall surface or the like supports an engaging recess provided on the back surface of the air conditioner main body to support the mounting arm. A locking piece having an inverted L-shaped hooking portion is provided on either one of the upper end of the air conditioner and the upper portion of the rear surface of the air conditioner main body, and the other end of the locking piece engages with the hooking portion of this locking piece. It is provided with a notch.

Further, in the air conditioner mounting device according to the present invention, a support arm provided on a mounting plate that is mounted on a wall surface or the like supports an engaging recess provided on the back surface of the air conditioner main body for support. The engaging surface on the mounting surface side extending from the abutting surface of the support arm of the engaging recess is inclined toward the mounting surface side, and a claw portion is provided at the tip of the inclined surface, and air is applied to the supporting arm of the installation plate. There is provided a locking hole into which the claw portion of the engaging recess fits and locks when the lower portion of the main body of the conditioner is inclined so as to be separated from the mounting surface by a predetermined angle.

[Action]

The engaging piece having the inverted L-shaped hooking portion and the U-shaped notch in the present invention are engaged with the notch when the air conditioner body is lifted, so that the holding arm of the installation plate can be removed. The air conditioner is supported even if the engaging recess of the air conditioner body is disengaged.

Further, the claw portion of the engaging recess and the locking hole of the support arm in the present invention engage and lock with each other when the lower portion of the air conditioner body is tilted so as to be separated from the mounting surface by a predetermined angle, and further. Do not tilt the air conditioner to the angle of.

In these drawings, the same reference numerals as those in FIGS. 6 to 9 are shown. Indicate the same components.

In FIG. 1 to FIG. 3, 1 is an air conditioner main body, 2 is a mounting plate mounted on a wall surface 3 with screws 4, 5 is a supporting arm provided on the upper part of the mounting plate 2, and 5a is a tip portion thereof. , 6 is a valve provided in the lower part of the installation plate 2, 7 is an engaging recess provided in the upper part of the rear surface 1a of the air conditioner body 1,
Reference numeral 8 is a lower support piece of the air conditioner body 1, which is fixed to the receiving piece 6 with a screw 9. 10 is a connecting pipe, 11 is a flare nut, 12 is an external pipe, 13 is an inverted L-shaped locking piece provided at the center of the upper end of the installation plate 2, and has an arm portion 14 protruding upward and this arm portion 14. From the rear side 1a of the air conditioner body 1
It consists of fifteen. 16 is the rear surface 1a of the air conditioner body 1
The U-shaped notch provided in the center of the upper part of the
It is provided so as to engage with the hook portion 15 of 13 and the vertical rib 17
It is formed integrally with.

When installing the air conditioner having the above-mentioned configuration, the installation plate 2 is fixed to the wall surface 3 as in the conventional case, the engaging recess 7 of the air conditioner main body 1 is hooked on the support arm 5, and the lower support piece 8 is attached. It is fixed to the receiving piece 6 of the installation plate 2 with the screw 9. This allows the second
As shown in the figure, the air conditioner can be mounted vertically on the wall surface 3.

Further, when performing the pipe connection work, as shown in FIG. 3, the lower portion of the air conditioner main body 1 is lifted around the engaging portion of the support arm 5 and the engaging concave portion 7 as a fulcrum, and is appropriately connected to the installation plate 2. The pipe 10 is connected at an appropriate interval. At this time, the inverted L-shaped locking piece 13 of the installation plate 2 including the arm portion 14 and the hook portion 15 projecting to the rear surface 1a side of the air conditioner body 1 is at a position higher than the position of the fulcrum. When the lower part of the air conditioner body 1 is lifted to a certain height, the notch 16 on the back surface 1a of the air conditioner body 1
The engagement concave portion 7 is not disengaged from the support arm 5 by engaging with the support arm 5. That is, when the engaging recessed portion 7 of the air conditioner body 1 is hooked on or removed from the support arm 5 of the installation plate 2, the locking piece 13 and the notch 16 are not engaged with each other, so that the installation work is easy and the piping work is easy.

The installation plate 2 may be provided with a U-shaped notch 16 at the upper end, and the same effect as that of the above-described embodiment can be obtained.

FIG. 4 is a side view showing another embodiment of the present invention, a part of which is cut away. FIG. 5 is a side view showing a state in which the lower portion of the air conditioner main body of FIG. 4 is tilted so as to be separated from the mounting surface.

In FIG. 4 and FIG. 5, 18 is the air conditioner body 1
With the claw portion provided in the engaging concave portion 7 on the rear surface 1a side, the engaging surface extending from the abutting surface of the support arm 5 of the engaging concave portion 7 and inclined to the wall surface 3 side which is the mounting surface ( It is provided at the tip of the inclined surface 7c and is formed so as to project toward the support arm 5 side of the installation plate 2. Reference numeral 19 is a locking hole provided in the support arm 5 of the installation plate 2, and when the lower part of the air conditioner main body 1 is tilted so as to be separated from the wall surface 3 by a predetermined angle, the claw portion 18 of the engagement concave portion 7 is fitted. It is formed so as to be locked and then serve as a stopper.

In addition, the above-mentioned predetermined angle is an angle which can maintain the distance between the air conditioner main body 1 and the wall surface 3 so that the piping work can be sufficiently performed. Further, the protruding height of the claw portion 18 is
The height is set so that the support arm 5 can be smoothly fitted into the engagement recess 7 when the air conditioner body 1 is hooked on the installation plate 2.

When the piping work of the air conditioner configured as described above is performed, as shown in FIG. 5, in a state where the lower support piece 8 of the air conditioner body 1 is removed from the receiving piece 6 of the installation plate 2, as shown in FIG. If you move the lower part of the machine body 1 away from the wall surface 3,
The claw portion 18 provided on the engaging surface 7c of the engaging concave portion 7 at a predetermined angle abuts against the end surface of the locking hole 19 provided in the support arm 5 of the installation plate 2 and serves as a stopper in the rotation direction, which serves as the engaging concave portion. The pipe work can be easily performed without the 7 being disengaged from the support arm 5. At this time, the air conditioner does not fall. Then, after the piping work, the lower part of the air conditioner body 1 is returned to the wall surface 3 side, and the support piece 8 is fixed to the receiving piece 6 with the screw 9, whereby the installation work is completed.

In addition, the claw portion 18 serving as a stopper in the rotation direction and the locking hole
19 may be provided at one or a plurality of positions of the engagement recess 7 or the support arm 5 provided in the air conditioner body 1 or the installation plate 2, and the same action and effect can be obtained.
