BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a mounting apparatus for an air-conditioning indoor unit according to a first embodiment of the present invention; The air-conditioning indoor unit body 9 and the mounting plate 1
Of the present invention is the same as that of the conventional example, the description is omitted, and the gist of the present invention will be described in detail.

As shown in FIG. 4, the width of the mounting pieces 7 formed on both sides of the lower part of the mounting plate 1 made of a deformable thin plate is formed wider than in the prior art, and one of the lower parts of the elastic mounting piece 7 is provided. And a tongue piece 7a having a locking hole 8 similar to the conventional one is integrally formed, and the slip-off preventing piece 1 is adjacent to the tongue piece 7a.
8 is formed integrally with the other of the lower part of the mounting piece 7. The detachment preventing piece 18 is formed by providing substantially bent portions at two places and bending in the same direction as the bending direction of the tongue piece 7a (the indoor unit main body 9 side). However, as shown in FIGS. 1 and 3, the lower edge of the detachment preventing piece 18 is located lower than the lower edge of the tongue piece 7a. That is, as shown in FIG. 3, a step B is provided between the tongue piece 7a and the lower edges of the detachment preventing piece 18. 1 and 2 when the locking claw 14 of the hook portion 11 of the bottom frame 10 and the locking hole 8 of the tongue 7a of the mounting piece 7 of the mounting plate 1 are inserted and locked.
As shown in FIG. 3, the lower edge of the separation preventing piece 18 is dimensioned so as to approach the upper surface of the bottom frame 10. FIG. 1 is FIG.
It is an expanded sectional view of X part in a middle. Further, as shown in FIG. 4, an elongated hole 19 is formed in the center of the detachment preventing piece 18, and a slit 20 is formed substantially in the center of the lower edge of the locking hole 8 of the tongue 7a. Are formed.

Next, the operation when the indoor unit main body 9 is mounted on the mounting plate 1 will be described. When the indoor unit main body 9 is brought to the front of the installation plate 1 after the installation plate 1 is attached to the wall surface side, the locking claws 14 of the bottom frame 10 of the indoor unit main body 9 are inserted into the locking holes 8 of the installation plate 1. I will do it. At this time, hook part 11
The lower surface of the locking claw 14 pushes down the lower portion of the locking hole 8, and when the step on the lower surface of the locking claw 14 is fitted into the locking hole 8, the lower portion of the tongue 7 a is elastically restored. Then, the locking claw 14 is inserted and locked in the locking hole 8. Here, when the locking claw 14 is inserted and locked in the locking hole 8, the detachment preventing piece 18 has the step B so as to be slightly above the position of the upper surface of the bottom frame 10 as described above. In addition, even when the bottom frame 10 is moved toward the mounting plate 1, the lower edge of the detachment preventing piece 18 does not hit or catch on the rear end surface of the bottom frame 10. The bottom frame 10 can be smoothly moved toward the installation plate 1, and the locking claws 14 can be locked in the locking holes 8. When the locking claw 14 is inserted and locked in the locking hole 8, the lower edge of the detachment preventing piece 18 comes to a position close to the upper surface of the bottom frame 10 as shown in FIG. 1. For this reason, when an upward force is applied to the bottom frame 10, the upper surface of the bottom frame 10 hits against the disengagement prevention piece 18 to restrict the upward movement of the bottom frame 10, and the locking claw 14 comes off from the locking hole 8. Can be prevented.
It should be noted that the dimension of the step B may be set so that when the locking claw 14 is locked in the locking hole 8, the lower edge of the separation preventing piece 18 is in contact with the upper surface of the bottom frame 10. good.

Next, a method of inserting and locking the locking claw 14 into the locking hole 8 using a string (pulling member) 21 as shown in FIGS. 6 to 8 will be described. In this method, the communication pipes 15 and the like disposed on the rear side of the indoor unit main body 9 swell, these hit the mounting piece 7 or the tongue piece 7a, the tongue piece 7a escapes, and the locking claw 14 is inserted into the locking hole 8. This is a countermeasure for cases where it is difficult to insert and lock smoothly. First, the string 21 is passed through a slit 20 formed in advance on the lower edge of the locking hole 8 of the installation plate 1, and the string 21 is passed between the hook portion 11 and the bottom frame 10 so that the end of the string 21 is brought forward. The part is drawn out through the cutout part 24 of the indoor unit main body 9. The tongue 7a is deformed forward by the elastic force of the tongue 7a, or the rearward displacement is restricted by pulling the string 21 toward the user in a state where the indoor unit main body 9 is pushed to the installation plate 1 side. The insertion and locking of the claw 14 and the locking hole 8 can be performed smoothly. And after locking the string 2
1 and pull out the string 21 with one end.

FIGS. 9 to 11 show a method using the holes 19 of the detachment preventing piece 18, and in this method, a synthetic resin clamp member (pulling member) 22 for binding electric wires is used. The clamp member 22 is inserted from the back into the hole 19 of the detachment preventing piece 18, and the clamp member 2 is inserted at the head 23 larger than the hole 19.
I try to pull 2. When the clamp member 22 is pulled, since the mounting piece 7 itself has elasticity, the rearward displacement of the detachment preventing piece 18 is restricted and the displacement of the adjacent tongue piece 7a is also restricted. 14 can be easily inserted and locked in the locking hole 8. Figure 1 after locking
As shown in FIG. 1, the clamp member 22 is cut at an appropriate place by a nipper or the like. In this case, the remaining clamp member 22 may be left as it is, or when the hand is accessed from below, the remaining clamp member 22 may be taken out. Further, instead of the clamp member 22, the string is passed through the hole 19 of the stripping prevention piece 18 as in the previous embodiment, and the stripping prevention piece 18 is pulled to deform the tongue piece 7a forward to engage the locking claw 14. You may make it lock in the stop hole 8.

When the locking claw 14 is inserted and locked in the locking hole 8 by pulling up the locking member 18 through the clamp material 22 (or a string) or the like into the hole 19 of the locking member 18, the locking is prevented. When the piece 18 is pulled up, the lower part of the detachment preventing piece 18 is curved upward, so that the size of the step B may be set to be slightly larger, and the action may be performed as follows. In other words, after the locking claws 14 are locked in the locking holes 8, the lower edges of the locking pieces 18 press the upper surface of the bottom frame 10 when the locking pieces 18 elastically return to the bottom frame 10. Even when a force is applied, the bottom frame 10 may be prevented from rattling. In this case, it is possible to more reliably prevent the locking claw 14 from coming off the locking hole 8.

[0020]

According to the apparatus for mounting an air-conditioning indoor unit of the first aspect, even when an upward force is applied to the bottom frame, the upper surface of the bottom frame hits the lower end of the disengagement preventing piece and the bottom frame moves upward. regulate. This can prevent the locking claw and the locking hole from being unlocked. Therefore, the locking claw and the locking hole can be reliably prevented from coming off without largely changing the product size and cost.

According to the second and third aspects of the present invention, when the pulling member is pulled, the rearward displacement of the lower portion of the mounting plate is restricted, and the displacement of the lower portion of the mounting plate is restricted. This makes it possible to smoothly insert and lock the locking claw with the locking hole formed in the c portion of the installation plate. Therefore, even in the case where the communication pipes etc. of the indoor unit body expands and the lower portion of the mounting plate escapes, the rearward displacement of the lower portion of the mounting plate on the locking hole side is restricted to lock with the locking claw. Can be easily and reliably performed. Therefore, an air-conditioning indoor unit that can be easily installed can be provided without largely changing the product size and cost.

Further, according to the method for mounting the air conditioner indoor unit, when the pulling member is pulled, the rearward displacement of the lower portion of the installation plate together with the detachment preventing piece is regulated. By restricting the displacement of the lower part of the mounting plate, the insertion locking of the locking claw with the locking hole formed in the lower part of the mounting plate can be performed smoothly. Therefore, even when the communication pipe of the indoor unit main body expands and the lower portion of the installation plate escapes, the locking between the locking hole and the locking claw can be easily and reliably performed. Therefore, an air-conditioning indoor unit that can be easily installed can be provided without largely changing the product size and cost.
