A heat exchanger 9 is provided between the air suction ports 3 and 4 and the cross flow fan 8, and cools the air sucked by the fan 8 during the cooling operation and sucks the air during the heating operation. It is designed to heat air. Note that an air filter 10 and the like are provided between the air suction ports 3 and 4 and the heat exchanger 9.
[0016]
A plurality of wind direction change plates 11 for changing the left and right blowing angles of the blown air are provided at the back side of the air outlet 5 so as to be rotatable in the left and right direction. .
[0017]
On the upper rear side of the exterior case 2 of the indoor unit 1, a hook portion 2 a that is hooked on hook pieces 12 a formed at two places on the upper right and left of the fixture 12 fixed to the installation wall 20 is formed.
[0018]
The mounting fixture 12 is made of an iron plate. As shown in FIGS. 1 to 3, the above-described hook pieces 12 a, 12 a protrude at two locations on the upper right and left sides, and the lower side is narrower. Its size is such that it is hidden by the installed indoor unit 1 as shown by a two-dot chain line in FIG. 1 to 3 show a case where the indoor unit 1 is installed at a corner between the ceiling 30 and the right side wall 40.
[0019]
Here, in the present embodiment, an inverted T-shaped positioning hole 13 is formed in a central portion on the upper side of the fixture 12. The positioning hole 13 is composed of a horizontal hole 13a that is long in a direction parallel to the hook pieces 12a, 12a, and an upward hole 13b that communicates upward from the center of the horizontal hole 13a and is long in a direction parallel to the side. Become. The positioning holes 13 are used to easily position the installation tool 12 at a predetermined position for installing the indoor unit 1.
[0020]
Therefore, the dimensions of the horizontal hole 13a and the upward hole 13b of the inverted T-shaped positioning hole 13 are determined as follows.
[0021]
That is, as shown in FIG. 3, assuming that the width of the indoor unit 1 is W1 and the width of the fixture 12 is W2, each length A from both ends of the horizontal hole 13a to the junction with the upward hole 13b is: ,
(W1-W2) / 2 <A Expression 1
Is set to satisfy a predetermined length. Specifically, this predetermined length A is １ ／ of the difference between the width W1 of the indoor unit 1 and the width W2 of the fixture 12, that is, the portion of the indoor unit 1 protruding from the side end of the fixture 12, and 1 and the side wall 40 so that the required length (S1) is added.
[0022]
On the other hand, as shown in FIG. 4, assuming that the height from the lower end of the hook portion 2 a formed on the upper rear surface of the indoor unit 1 to the upper end of the indoor unit 1 main body is C, the height in the inverted T-shaped positioning hole 13 is upward. The length B of the hole 13b, that is, the length B from the upper end of the upward hole 13b to the junction with the lateral hole 13a is:
C <B ... Formula 2
Is set to satisfy a predetermined length. Specifically, since this predetermined length B is the distance between the upper end of the hooking piece 12 a protruding from the upper side of the fixture 12 and the ceiling 30, this interval is the hooking portion 2 a of the indoor unit 1. (The distance through which the hook portion 2a can pass) and the length in consideration of the gap (S2) required between the indoor unit 1 and the ceiling 30.
[0023]
Although not shown, as described above, the mounting fixture 12 has a large number of selectively usable screw holes in order to correspond to the mounting wall 20 in which the places that can be screwed and fixed are limited to each wall. Have been.
[0024]
Now, in the present embodiment configured as described above, the fixture 12 can be correctly attached to the installation position of the indoor unit 1 as shown in FIGS.
[0025]
That is, first, as shown in FIG. 1, the fixture 12 is placed in the inverted T-shaped positioning hole 13 with the upper end (the upper end of the hook 12 a) and the right end of the fixture 12 abutting against the ceiling 30 and the right wall 40, respectively. It is temporarily fixed with a screw 14 to the left end of the horizontal hole 13a. Note that even if this portion is a wall surface that cannot be securely screwed with the screw 14, there is no problem because it is a temporary fixing.
[0026]
Next, as shown in FIG. 2, the mounting fixture 12 is moved so that the temporary fixing screw 14 comes to the central position of the lateral hole 13a of the inverted T-shaped positioning hole 13, that is, the junction with the upward hole 13b. Move sideways.
[0027]
Then, as shown in FIG. 3, the mounting tool 12 is moved right below so that the temporary fixing screw 14 reaches the upper end position of the upward hole 13b. At this position, the fixing device 12 is firmly fixed with an appropriate screw hole which can be fixed by screwing, and the hook 2a on the upper rear surface of the indoor unit 1 is hooked on the hook piece 12a on the upper side of the fixing device 12. Thereby, the indoor unit 1 is correctly installed at the installation position. At this time, the exterior case 2 of the indoor unit 1 is installed with appropriate gaps S1 and S2 without hitting the ceiling 30 or the side wall 40.
[0028]
As described above, according to the present embodiment, the installation position can be easily determined without using a scale or the like and without temporarily installing the indoor unit 1, and the installation work can be greatly simplified.
[0029]
By the way, in the above description, the right part of the inverted T-shaped positioning hole 13 is not used. However, this is for the example of installing the indoor unit 1 at the corner between the ceiling 30 and the right side wall 40. On the other hand, when it is installed on the corner between the ceiling 30 and the left side wall, the right side is used. By using the inverted T-shaped positioning hole 13 in this manner, it is possible to cope with the installation at any of the left and right corners. An L-shaped positioning hole for each corner may be provided.
[0030]
Further, in the above embodiment, one inverted T-shaped positioning hole 13 is provided at the upper center position of the fixture 12, but such an inverted T-shaped positioning hole 13 is provided at intervals such as left and right or up and down. By providing one, the temporary fixing can be performed by two-point support, so that the final fixing operation performed in the state shown in FIG. 3 can be easily performed without worrying about the rotational position shift of the fixture 12.
[0031]
Although it is possible to provide three or more inverted T-shaped positioning holes 13, two-point support is sufficient to prevent the rotational position of the fixture 12 from shifting, and the labor and the like by providing three or more are considered. And two are the most effective.
[0032]
On the other hand, when the positioning hole 15 having the shape shown in FIG. 5 is provided instead of providing the two inverted T-shaped positioning holes 13 as described above, the same effect as described above can be obtained. There is an advantage that only one hole is required.
[0033]
That is, the positioning hole 15 of the embodiment shown in FIG. 5 includes a horizontal hole 15a and two upward holes 15b, 15b communicating with the horizontal hole 15a and formed at an arbitrary interval D. Each length A from both ends of the horizontal hole 15a to the confluence of the upper holes 15b, 15b is set to a predetermined length that satisfies the expression 1 as in the above embodiment. Also, the length B of the two upward holes 15b, 15b is set to a predetermined length that satisfies Equation 2 as in the above embodiment.
[0034]
Further, in addition to the first temporary fixing screw 16a temporarily fixed to the end of the lateral hole 15a, a second temporary fixing screw 16b is required, and the second temporary fixing screw 16b is used as the first temporary fixing screw 16b. The screw 16a must be screwed at the same interval D as the interval D between the upper holes 15b, 15b. For this reason, a mark 15c is formed as a mark for screwing the second temporary fixing screw 16b at a position separated by a distance D from both ends of the horizontal hole 15a.
[0035]
Usually, two marks 15c are required on the left side and the right side. However, in this embodiment, the distance D between the upper holes 15b, 15b is set to 2A, so that one common mark 15c is formed. I'm doing it. Thereby, it is possible to prevent the mark of the second temporary fixing screw 16b from being mistaken in the case of installation on the right side wall side and the case of installation on the left side wall side in the room.
[0036]
【The invention's effect】
As described above, according to the present invention, a positioning hole having a lateral hole that is long in a direction parallel to the hooking piece and an upward hole that is long in a direction parallel to the side is provided in the fixture of the air conditioner body. The upper hole is disposed above the horizontal hole, and the upper hole and the horizontal hole communicate with each other.The length from the end of the horizontal hole to the junction with the upper hole is defined as the air conditioner body width. The length from the upper end of the upward hole to the junction with the horizontal hole is determined by the length from the lower end of the hook to the upper end of the air conditioner body. Since it was formed to a long predetermined length, the upper end and the side end of the fixture were temporarily fixed to the other end of the horizontal hole with the upper end and the side end being respectively applied to the ceiling or the side wall, and the temporary fixing screw was turned upward. By simply moving the fixture so that it is at the upper end of the hole, the fixture can be accurately positioned at the main body installation position. Therefore, the installation position can be easily determined without using a scale or the like and without temporarily installing the main body, and the installation work can be greatly simplified.
[0037]
In addition, by forming the positioning hole in an inverted T-shape, in addition to the above-described effects, it is possible to cope with installation at any of the left and right corners.
[0038]
In addition, by providing the two inverted T-shaped positioning holes, in addition to the above-described effects, the fixing work of the fixture can be easily performed without worrying about the rotational position shift of the fixture.
[0039]
Further, since the positioning hole has a horizontal hole and two upper holes formed at an arbitrary interval in the horizontal hole, the same effect as above can be obtained, and the positioning hole can be obtained. There is an advantage that only one is required.
