[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an installation apparatus 10 according to the present invention, and FIG. 2 is a cross-sectional view showing a state when the indoor unit 5 is installed in the installation apparatus 10. FIG. 3 is a diagram showing a procedure for marking the formation position of the refrigerant piping hole 6 using the installation device 10. In addition, in FIG. 3, in order to clarify the positional relationship with the indoor unit 5 and the refrigerant | coolant piping hole 6, these are shown with the dotted line.
[0013]
An upper engagement piece 11 that engages with the engagement member 7 of the indoor unit 5 is provided on the left and right of the upper end of the installation device 10, and a lower engagement piece 12 is provided on the left and right of the lower end of the installation device 10. It is formed at a substantially peripheral end.
[0014]
Thus the width and height of the installation device 10 can be minimized in size, with size and weight of the mounting device 10 is enabled, so the material cost can be cheap Kusuru It has become.
[0015]
In addition, a temporary fixing hole 13 is formed on the vertical center line of the installation device 10, and a plurality of through holes 14 for fixing when the installation device 10 is screwed to the wall 2 are formed at appropriate positions. . Of course, it does not have to be screwed using all the through holes 14 shown in the drawing, and may be appropriately selected and used in accordance with the spacing of the neda and the like.
[0016]
In addition, the code | symbol P shown in FIG. 1 or FIG. 3 is addressed to the indoor unit back formed so as to rise toward the indoor side. The indoor unit 5 is fixed by the upper engagement piece 11 and the lower engagement piece 12 as described above, but the entire housing of the indoor unit 5 is not fixed. For this reason, for example, the vibration of the cross flow fan 8 or the like built in the indoor unit 5 may resonate in the housing and generate a large noise. Therefore, the installation device 10 is provided with an indoor unit back address P to suppress the vibration of the housing and the like, thereby suppressing the generation of the noise.
[0017]
The left and right lower corner portions 15 of the installation device 10 are formed in an arc shape. This is to prevent the refrigerant pipe from hitting the installation device 10 when a refrigerant pipe (not shown) is passed through the refrigerant pipe hole 6. A first mark 16 is formed in the vicinity of the lower end corner portion 15.
[0018]
Further, in the vicinity of the left and right end portions of the installation apparatus 10, a tongue-like piece 18 having a notch 17 formed in a substantially “U” shape is provided. A claw engagement portion 21 is provided on the center side of the installation device 10 of the tongue 18 and a second mark 20 is formed at a predetermined position.
[0019]
As will be described later, the tongue-like piece 18 is used by being bent in the width direction at a connecting portion (indicated by a one-dot chain line) 19. At that time, the tongue-shaped piece 18 is easily raised by putting a nail or a finger on the nail engaging portion 21.
[0020]
The first mark 16 and the second mark 20 constitute a mark portion, which is formed by a method that does not easily disappear or shift by punching or stamping, and has the following meanings.
[0021]
That is, the indoor unit 5 and the outdoor unit (not shown) are configured so that the refrigerant circulates through the refrigerant pipe, and these are provided with a pipe connection portion (not shown) that forms a connection port with the refrigerant pipe. Yes.
[0022]
The first mark 16 indicates the height position of the pipe connection portion of the indoor unit 5 when the indoor unit 5 is attached to the installation apparatus 10. The second mark 20 indicates the lateral position of the pipe connecting portion when the tongue-like piece 18 is bent in the width direction at the connecting portion 19.
[0023]
By the way, the tongue-shaped piece 18 and the mark portion are provided on the left and right sides, so that the refrigerant pipe hole 6 can be provided on either the left or right side of the indoor unit 5 so that the installation apparatus 10 can be generalized. This is to enable cost reduction.
[0024]
Therefore, when the refrigerant piping hole 6 is provided only on either the left or right side of the indoor unit 5, it goes without saying that these may be provided only on either one.
[0025]
As shown in FIGS. 1 and 3, the position of the second mark 20 is left-right asymmetric. This is due to the following reason.
[0026]
That is, generally, the pipe connection part of the indoor unit 5 is provided in the vicinity of the right end with respect to the drawings of FIGS. Moreover, although refrigerant | coolant piping is comprised by the moderately flexible member, if it bends suddenly, a pipe | tube will bend or will be crushed.
[0027]
Therefore, when the refrigerant pipe hole 6 is formed on the right side of the indoor unit 5, it is preferable to form the refrigerant pipe hole 6 at the position of the pipe connecting portion so as to eliminate the bending of the refrigerant pipe.
[0028]
However, the refrigerant pipe hole 6 may not be formed on the right side of the indoor unit 5 depending on the outdoor situation, for example, when there is an obstacle at the position of the outer wall corresponding to the pipe connection portion. .
[0029]
In such a case, the refrigerant piping hole 6 is formed on the left side of the indoor unit 5. At this time, in order to prevent the connection position between the refrigerant pipe and the pipe connection portion from reaching the refrigerant pipe hole 6, it is preferable to form the refrigerant pipe hole 6 on the left side as much as possible.
[0030]
In addition, the refrigerant pipe is arranged between the indoor unit 5 and the installation device 10 and is piped to the outside from the refrigerant pipe hole 6. Of course, it goes without saying that the indoor unit 5 is prevented from floating from the installation device 10 by the refrigerant connection pipe or the like.
[0031]
At this time, if the refrigerant pipe can be bent slowly in the space K on the back side of the indoor unit 5 (see FIG. 2) and can be piped into the refrigerant pipe hole 6, the refrigerant pipe hole 6 can be formed symmetrically. .
[0032]
However, since the indoor unit 5 and the installation device 10 are in contact with each other at the place P directed to the back of the indoor unit, the refrigerant pipe cannot be bent slowly at the space K.
[0033]
Therefore, it is necessary to bend the refrigerant pipe in a place where there is no P for the indoor unit, and for this reason, the position of the refrigerant pipe hole 6 is shifted to the left side.
[0034]
Next, a procedure for installing the indoor unit 5 using the installation apparatus 10 having such a configuration will be described.
[0035]
First, the tongue-shaped piece 18 in the direction in which the refrigerant piping hole 6 is formed is bent at the connecting portion 19 and the installation apparatus 10 is temporarily fixed in this state.
[0036]
The temporary fixing position is a position where the front end in the width direction of the bent tongue piece 18 is about 80 mm away from the lateral wall 3 and the upper engagement piece 11 is about 50 mm away from the ceiling, and the installation device 10 is pressed to that position. The position of the temporary fixing hole 13 is marked.
[0037]
In addition, the width direction front end of the tongue-shaped piece 18 is set at a position about 80 mm away from the lateral wall 3 because the width direction front end of the tongue-shaped piece 18 is about 30 mm away from the side end of the facing indoor unit 5. This is because, when the unit 5 is attached, the distance between the indoor unit 5 and the lateral wall 3 is secured by 50 mm so that the indoor unit 5 can be held by hand.
[0038]
Therefore, it is necessary to set the above dimensions according to the size of the indoor unit 5, that is, the distance between the front end of the tongue-shaped piece 18 in the width direction and the side end of the indoor unit 5 facing it.
[0039]
On the other hand, the reason why the upper engagement piece 11 is about 50 mm away from the ceiling is that the engagement member 7 is inserted into the upper engagement piece 11 from above, so that at least the size of the engagement member 7 can be accommodated. This is to ensure.
[0040]
Further, in recent years, the indoor unit 5 has been miniaturized, and as can be seen from FIG. 2, an intake port for sucking room air is formed not only on the front surface of the indoor unit 5 but also on the upper surface. Therefore, if the upper surface is too close to the ceiling, the intake efficiency is lowered. Therefore, the size is set larger in order to avoid this. Of course, it is needless to say that it is not necessary to take this into consideration when no intake port is provided on the upper surface.
[0041]
Thus, after marking the position of the temporary fixing hole 13, the installation apparatus 10 is once lowered, and a screw or a nail is driven into the mark position. At that time, the head of the screw or nail is left in a predetermined amount, and the fixing hole 13 is inserted into the head to suspend the installation device 10.
[0042]
Since the temporary fixing hole 13 is formed on the vertical center line of the installation device 10, the right and left balance can be substantially maintained even if the operator releases the hand from the installation device 10. Therefore, the installation apparatus 10 is fixed with screws or the like.
[0043]
Thereafter, the refrigerant pipe hole 6 is formed at the intersection between the direction of the first mark 16 and the direction of the second mark 20, and the refrigerant pipe and the pipe connection portion are connected to fix the indoor unit 5 to the installation apparatus 10.
[0044]
【The invention's effect】
As described above, according to the first aspect of the present invention, the mark portion including the first mark indicating the height direction formation position of the refrigerant pipe hole and the second mark indicating the horizontal direction formation position, and the width direction is bent. And a second mark is formed on the tongue-shaped piece , and the installation device is formed smaller than the indoor unit, and the tongue-shaped piece is bent in the width direction. In this case, since the tip in the width direction of the tongue-shaped piece is formed to be smaller than the indoor unit by a predetermined amount , the direction indicated by the first mark and the second mark by bending the tongue-shaped piece in the width direction The point of intersection with the direction indicated by shows the formation position of the refrigerant piping hole, so that the size of the installation device can be minimized, and positioning of the refrigerant piping hole can be done without using a scale or the like. Can be done easily, cost reduction and workability improvement Possible to become.
[0046]
In the invention according to claim 2 , since the mark portion and the tongue-like piece are provided in the vicinity of the left and right end portions of the installation device, and the second mark is formed asymmetrically, the position of the refrigerant piping hole is set to the indoor unit. It can be formed at either the left or right position, increasing the versatility of the installation device, making it easy to position the refrigerant piping holes without using a scale, etc. Therefore, the cost can be reduced and the workability can be improved.
[0047]
According to the third aspect of the present invention, since the temporary fixing hole is formed on the vertical center line of the installation device, the fixing operation of the installation device is facilitated.
