BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting an indoor unit of an air conditioner.

[0002]

2. Description of the Related Art FIG. 4 is an exploded perspective view of a case where an installation plate 1 is mounted on a wall surface side. Fix with 5. Then, the installation plate 1 is arranged in parallel on the front surfaces of the installation bars 4, 4, and the installation plate 1 is fixed to the installation bars 4, 4 by tapping screws 6. After the installation plate 1 is fixed to the wall surface side, the indoor unit main body of the air conditioner is removably arranged by fitting concave and convex. Here, mounting pieces 7 formed in a substantially rectangular shape are integrally formed on both sides of a lower portion of the mounting plate 1. A square locking hole 8 is formed in the mounting piece 7 as shown in FIG.

As shown in FIG. 7, a hook portion 1 is provided on an upper surface of a bottom frame 10 of an indoor unit main body 9 attached to the mounting plate 1.
1 are integrally formed. The hook portion 11 is provided with four standing support pieces 12, a plate-shaped locking piece 13 integrally extending from an upper portion of the supporting piece 12, and protrudes downward from a tip portion of the locking piece 13. Claw 1 integrally formed as described above
4. Then, in a state where the upper part of the indoor unit main body 9 is rotatably suspended above the mounting plate 1, the locking claw 14 of the hook portion 11 is inserted and locked into the locking hole 8 of the mounting plate 1, whereby the indoor unit is locked. The main body 9 is detachably attached to the installation plate 1. As shown in FIG.
Is moved rearward as it is to be inserted and locked in the locking claw 14 and the locking hole 8, and the lower surface of the tip of the locking claw 14 contacts the lower edge of the mounting piece 7 to push down the elastic mounting piece 7 downward. .
When the locking claw 14 enters the locking hole 8, the mounting piece 7 is elastically restored to a state as shown in FIG. As a result, the locking claw 14 and the locking hole 8 are securely locked, and the indoor unit body 9
Is mounted on the mounting plate 1.

FIG. 6 shows a state in which a connecting pipe 15, a connecting wiring 16, a drain hose 17 and the like are arranged inside the indoor unit main body 9 and in front of and above the hook portion 11. The hook 11 is formed on the upper surface of the bottom frame 10,
When the locking piece 8 is locked with the locking hole 8 of the mounting piece 7, the mounting piece 7 is urged downward. Therefore, the locking claw 14 is formed at a position floating above the upper surface of the bottom frame 10. Therefore, as shown in FIG. 6, the lower edge of the mounting piece 7 is located above the upper surface of the bottom frame 10 when the locking claw 14 and the locking hole 8 are locked as shown in FIG. A gap having a predetermined size is generated between the portion and the upper surface of the bottom frame 10.

Incidentally, in the above conventional example, the indoor unit body 9
If itself floats toward the ceiling due to the positional relationship of the connection piping,
Since there is a gap A between the lower edge of the mounting piece 7 of the mounting plate 1 and the upper surface of the bottom frame 10, the locking claw 14 of the hook 11 is likely to be easily released from the locking hole 8 of the mounting plate 1. There was a problem.

Therefore, the problem of the conventional example is solved by the structure shown in FIGS. 9 to 13, and this structure is the premise of the present invention as described later. As shown in FIG. 12, 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 made wider than before, and one of the lower parts of this elastic mounting piece 7 is provided with the same shape as the conventional one. The locking tongue 8 is formed integrally with the tongue 7a, and the detachment preventing piece 18 is integrally formed adjacent to the tongue 7a with the other of the lower part of the mounting piece 7. The disengagement preventing piece 18 is provided with a substantially bent portion at two places to provide a bending direction of the tongue piece 7a (the indoor unit main body 9).
Side) and bent in the same direction. However, as shown in FIG. 9 and FIG.
8 is formed so that the lower edge is located below.
That is, as shown in FIG.
A step B is provided between the lower edge 8 and both lower edges. The size of the step B is shown in FIGS. 9 and 10 when the locking claw 14 of the hook portion 11 of the bottom frame 10 is inserted and locked in the locking hole 8 of the tongue 7a of the mounting piece 7 of the mounting plate 1. The lower edge of the stripping prevention piece 18 is so dimensioned as to approach the upper surface of the bottom frame 10 as described above. FIG. 9 is an enlarged sectional view of a portion X in FIG.

Next, the operation when the indoor unit 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 is located below the locking hole 8 (the tongue 7a).
At the time 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, so that the locking claw 14 is Inserted and locked.
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 to the installation plate 1 side, the bottom frame 10 is smoothly moved to the installation plate 1 side without the lower edge of the detachment preventing piece 18 hitting or catching on the rear end surface of the bottom frame 10. Can be the locking claw 14
Can be locked in the locking holes 8. And locking claw 14
9 is inserted into 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. 9. 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.

[0008]

In the above-described mounting structure, although the locking portion between the bottom frame 10 and the mounting plate 1 is provided with the detachment preventing piece 18 so as not to be inadvertently detached as described above, When it is necessary to remove the indoor unit main body 9 from the installation plate 1 for relocation of the indoor unit main body 9 or confirmation at the time of construction, the locking claw 14 has a substantially triangular cross section and a certain width. Since it has a length, the locking claw 1
When releasing the bottom frame 4, it is necessary to lift the bottom frame 10 and forcibly bend the release prevention piece 18, which restricts the movement of the bottom frame 10, upward to release it. On this occasion,
In some cases, it is necessary to insert a flathead screwdriver or the like from the notch 24 shown in FIG. 10 and pry the locking piece 13 of the hook 11 upward to release the locking claw 14. In such a releasing method, there have been problems that the bottom frame 10 damages the detachment preventing piece 18 and that the locking claw 14 and the locking hole 8 cannot be easily released. Moreover, when releasing, it requires the use of a tool and a great deal of power, which is dangerous when working at a high place.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and an object of the present invention is to make it possible to easily remove a retaining claw from a retaining hole while maintaining a secure fixation.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a mounting apparatus for an indoor unit of an air conditioner according to an embodiment of the present invention. In addition, the indoor unit body 9 and the mounting plate 1 of the air conditioner
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.

FIG. 2 shows the bottom frame 10 side, and FIG. 3 shows the mounting plate 1 side. FIG. 1 is a view showing a case where the locking claw 14 is inserted and locked in the locking hole 8. 1 and 2
As shown in (a), the lower surface of the end of the locking claw 14 on the side of the disengagement prevention piece 18 is cut out to form a so-called R-shaped curved surface, which is a curved surface portion 25. A curved surface portion 25 formed on one of the lower surfaces of the locking claws 14 escapes when the locking claws 14 are released from the locking holes 8, without raising the locking claws 14 on the side of the disengagement preventing piece 18 too much. The locking claw 14 on the side opposite to the curved surface portion 25 is lifted to release from the locking hole 8. That is, when the end opposite to the curved surface portion 25 is pushed up, the engaging pawl 14 itself does not rise so much on the curved surface portion 25 side but rises on the opposite side to the curved surface portion 25.
Since the curved surface portion 25 has a cutout shape, the locking claw 14 can be easily released from the locking hole 8 even if the locking claw 14 itself rises while tilting. Moreover, locking claw 1
The curved surface portion 25 enables a smooth releasing operation without being caught on the edge of the locking hole 8.

Here, the bottom frame 10 is pushed upward to push up the locking claws 14, and the pushed portion is located on the opposite side of the detachment preventing piece 18. This is because, when the detachment preventing piece 18 is pressed, the detachment preventing piece 18 is forcibly bent as described above. In order to prevent this, the curved surface portion 25 of the locking claw 14 is disengaged. It is formed on the side. Then, as shown in FIG. 2B, a mark 26 is stamped at a position where the locking claw 14 is released when the lower surface of the bottom frame 10 is pressed. Of course, the mark 26 may be formed by a method other than engraving, such as printing or sticking. FIG.
Mark 26 on the lower surface of the bottom frame 10 as indicated by the arrow
When the bottom frame 10 is pushed upward, the bottom frame 10 bends and the end of the locking claw 14 on the side opposite to the curved surface 25 is lifted, and the cutout curved surface 25 is a relief. Release from the stop hole 8 can be easily performed. Therefore, safety can be ensured even when working at heights. Further, even if the bottom frame 10 is pushed upward at the position of the mark 26, since the curved surface portion 25 of the locking claw 14 is recessed, it does not rise so much, so the detachment preventing piece 18
The part of the bottom frame 10 on the side does not rise too much. Therefore, the lower end of the separation preventing piece 18 does not contact the upper surface of the bottom frame 10. Further, even if it comes into contact, the amount of deflection of the detachment preventing piece 18 is small, and the bottom frame 10 is pushed up at the position of the mark 26 to smoothly release the locking claw 14 without requiring a large force to damage the detachment preventing piece 18. be able to. As shown in FIG. 2, a flathead screwdriver or the like may be inserted from the notch 24 at the rear of the bottom frame 10 to lift the end of the locking claw 14 to release the locking claw 14 from the locking hole 8. In both cases, the cut-out portion of the curved surface portion 25 becomes a relief simply by pushing up the portion of the locking claw 14 opposite to the curved surface portion 25, so that the locking claw 14 can be easily removed from the locking hole 8. It is.

The insertion and locking of the locking claw 14 and the locking hole 8 is the same as the structure premised in the present application, and can be reliably locked, and the lower end of the disengagement prevention piece 18 is connected to the bottom frame. 1
By being close to the upper surface of the bottom frame 0, even when an upward force is applied to the bottom frame 10, the locking claw 14 does not easily come off the locking hole 8. Therefore, when releasing the lock while maintaining the secure fixation of the lock claw 14 and the lock hole 8, the release of the lock claw 14 can be facilitated by the escape of the curved surface portion 25 of the lock claw 14. Things.

[0020]

According to the apparatus for mounting an indoor unit of an air conditioner according to the first aspect, when the locking claw and the locking hole are released, the notched end of the locking claw is in contact with the notched end. By pressing the opposite side portion, the cut-out portion becomes a relief, and release from the locking hole can be easily performed. Therefore, the locking pawls can be easily removed when releasing the locking pawls while maintaining the secure fixing between the locking pawls and the locking holes by the detachment preventing pieces.

According to the air conditioner indoor unit mounting device of the second aspect, the notch surface of the locking claw is formed into a curved surface, so that the edge of the locking hole is formed when the locking claw comes out of the locking hole. Smooth release operation can be performed without being caught on the part.

According to the mounting device for an indoor unit of an air conditioner of the present invention, the locking claw can be released from the locking hole only by pressing the position of the mark, so that a tool is not required unlike the related art.
