Reference numeral 11 is a connection valve, and this connection valve 11
A refrigerant pipe 12 connected to an indoor unit (not shown) is connected to a and 11b so that the indoor unit and the outdoor unit 1 constitute a refrigeration cycle.

The connection valve 11 is the valve fixing plate 10 described above.
Of the refrigerant pipe 1 through the holes 10d and 10g of the
4 or the refrigerant pipe 15 has a refrigerant pipe connection portion 11g to which the refrigerant pipe 15 is brazed and connected, and as shown in FIGS. 15 to 17, a screw 12a of the refrigerant pipe 12 on the high pressure side or the low pressure side for connecting with the indoor unit. Refrigerant pipe connection portion 11e to which is connected
And a cap nut 11c to be removed when opening and closing the refrigerant conduction operation valve provided inside, and to be removed when air purging is performed by operating the built-in valve after the installation of the refrigerant pipe and other installation work are completed. Cap nut 11f
And have.

Since the connection valve 11b to which the refrigerant pipe 12 on the high pressure side is connected does not need a valve and a cap nut 11f for performing air purging, it is common to use a structure without this valve. Target. The high pressure side refrigerant pipe 12 having a small outer diameter and easy to be bent is attached to the valve 11b located on the convex portion 10f apart from the concave portion 6e, and the low pressure side is larger in outside diameter than the high pressure side refrigerant pipe 12 and is difficult to handle. Connecting the refrigerant pipe 12 of the connection valve 11 to the convex portion 10c of the upper cover 6 on the side closer to the concave portion 6e.
It was attached to a.

In this case, the refrigerant pipe 12 is attached to the low-pressure side refrigerant pipe 12 which has a large outer diameter and is difficult to handle.
If the flare nut 12a of the refrigerant pipe 12 is attached to the connection valve 11a and then the high pressure side refrigerant pipe 12 is attached, it does not hinder the turning of the flare nut 12a of the refrigerant pipe 12 with a tool and can be easily bent, so that the low pressure side refrigerant pipe 12 can be bent. Since the low-pressure side refrigerant pipe 12 and the high-pressure side refrigerant pipe 12 can be compactly bundled, they can be drawn out of the outdoor unit 1.

The connecting valve 11 is attached so as to be orthogonal to the inclined portion of the convex portion formed so that the side surface of the heat exchanger 3 is lowered by squeezing the valve fixing plate 10 as described above.
Therefore, the connecting nuts 11a and 11b are not
When the tool 13 is applied, the tool 13 is not disturbed by the side end 9a of the electrical component box 9. Of course, at this time, the connecting valves 11a, 11
The height of attachment of b to the inclined portion is also set.
That is, the flare nut 12a of the refrigerant pipe 12 is not only placed at a position where the connecting valves 11a and 11b are too close to each other so that the use of the tool is not interfered, but also when the refrigerant pipe 12 is connected to the conduit portion 11e of the connecting valve. The position is set so that it can be turned using a tool.

Furthermore, the flare nut 1 of this refrigerant pipe 12
In order to make it easier to rotate 2a with a tool, as shown in FIG. 4, the positions and sizes of the convex portions 10c and 10f of the valve fixing plate 10 are set so as to prevent the flare nut 12a from being operated and rotated by the tool. I try not to become.

A suction pipe (low pressure) 14 has one end connected to the preceding connecting valve 11a and the other end connected to a pipe on the compressor 2 side.
And 15 is a discharge pipe (high pressure). These tubes 14, 15
As shown in FIGS. 1 and 6, is connected to the refrigerant pipe connecting portion 11g of the connecting valves 11a and 11b in a direction orthogonal to the inclined portion of the valve fixing plate 10.

Reference numerals 14a and 15a are bent portions provided in the middle of the pipes 14 and 15. The function of the bent portions 14a and 15a is to use a tool when connecting the refrigerant pipe 12 to the connecting valves 11a and 11b. When turning the flare nut 12a and turning the cap nut 11c using the tool 13 after connecting the refrigerant pipe 12, the connection valves 11a and 11b also rotate to some extent according to the rotating movement of the tool 13. try to. This is to prevent stress from being applied to the welded portions of the pipes 14 and 15 when rotated. That is, the pipes 14 and 15 are connected to the bent portion 14
a and 15a are provided to make it easier to bend and rotate
It is absorbed by the bending of 14a and 15a.

The bent portions 14a and 15a are provided so as to be located in the space surrounded by the heat exchanger 3 and the valve fixing plate 10 which is out of the rotational trajectory of the blower 8. By effectively utilizing this space, the pipes 14 and 15 can be attached in a direction orthogonal to the inclined portion of the valve fixing plate 10, and the bent portions 14a and 15a can be provided.

Next, a handle for carrying the outdoor unit 1 will be described with reference to FIGS. As shown in FIGS. 1 and 4, the handles 16 and 17 are on the substantially same plane (that is, at substantially the same height) of the upper portion of the outdoor unit 1 and at a substantially intermediate position in the depth direction (the center of gravity of the outdoor unit and It is provided at a position where they substantially match each other.

The handle 16 is provided on the decorative cover 5, and the handle 17 is provided on the top cover 6 side. Therefore, when the top cover 6 is removed, the handle 17 is also removed together. Therefore, when the refrigerant pipe 12 is connected to the connection valve 11, the handle 17 is removed by removing the upper cover 6, and the handle 17 protruding toward the connection valve 11 does not hinder the connection work, and the workability can be improved. . Moreover, since the handle 17 is housed inside the outdoor unit by utilizing the space above the heat exchanger 3 where the connection valve 11 is housed, the heat exchanger 3 is an obstacle when the handle is provided. However, it can be provided substantially in the middle of the outdoor unit in the depth direction as described above.

Therefore, the heat exchanger is arranged so that it is located in a clearance space in which the heat exchanger is not arranged (for example, a clearance space formed between the bent portion of the heat exchanger and both side corners of the back surface of the outer box). Compared to the case where the outdoor unit is located far from the center of gravity, the outdoor unit 1 can be provided at a position that matches the center of gravity of the outdoor unit 1. Therefore, it is easy to carry and the weight is difficult to shift to one handle. By dividing the top cover that covers the connection valve 11 into a plurality of parts, and making it possible to remove only the cover of this part, it is not necessary to remove the entire top cover, it is easy to work, and the piping can be installed on a rainy day. Even when working, it is possible to prevent rain from dropping and adhering to electrical parts, which can prevent a failure.

Further, the upper cover is used for the connection valve 11
It is also possible to reduce the height of the other portions so as to reduce the overall height dimension as compared with the height of the portion that covers. Furthermore, when the portion of the upper surface cover that covers the connection valve 11 is divided, when removing the portion that covers the connection valve 11 and connecting the refrigerant pipes, the height of the other portions is low, so that it does not become an obstacle, Workability is improved. Reference numeral 18 is a guard net for protecting the outer periphery of the heat exchanger from the outside, and the guard net 18 may not be attached.

The case of performing the installation work of the outdoor unit 1 having such a configuration will be described below. The outdoor unit 1 is installed so as not to have a large gap with the wall 21 of the building as shown in FIG. Therefore, even if the tool is operated from the wall 21 side so that the cap nut 11c is removed and the internal valve is operated to bring it into conduction after the installation of the refrigerant pipe is completed, a space necessary for the operation of the tool is not ensured. Work is difficult.

In the case of the present embodiment, the handle portion of the tool 13 is set in consideration of the angle and height of the inclined portion provided on the valve fixing plate 10 so that the tool 13 does not hit the end 9b of the electric component box 9. The workability is improved by allowing the work to be performed while being positioned above the electrical component box 9.

The refrigerant pipe 12 is firmly screwed to the connecting valves 11a and 11b by using the tool 13. At this time, since the projecting heights of the connecting valves 10a and 10b from the valve fixing plate 10 are set to be different from each other, the above work is facilitated. That is, the convex portion 10c on the side closer to the concave portion 6e provided on the rear surface side of the upper surface cover 6 is lowered, and the convex portion 10f on the far side is raised to increase the convex portion 10 on the near side.
c or the connection valve 11 attached to the convex portion 10c
, The connection valve 1 attached to the distant convex portion 10f
It is possible to prevent the first refrigerant pipe 12 from coming into contact with or coming too close. Instead of changing the height of the protrusion, the connection valve 11
The height dimension of may be changed.

In addition to the angle and height of the inclined portion, the longitudinal direction of the inclined portion of the convex portion 10c nearer to the concave portion 6e is substantially the same as the rear surface of the outdoor unit 1 as shown in FIG. Provided in parallel, the longitudinal direction of the inclined portion of the convex portion 10f on the far side,
It is provided obliquely with respect to the back surface of the outdoor unit 1, whereby the refrigerant pipe 12 connected to the connection valve 11b on the far side is
It is possible to make the angle and height of the inclined part smaller than when it is attempted to achieve it only by the angle and height of the inclined part so that the convex part on the near side or the connection valve on the near side does not come into contact with or come too close. Since it is small, workability is further improved.

After the above connecting work is completed, the upper cover 6 is attached, and the electrical component box 8 and the connecting valve portion 11 are connected.
To cover.

Although the outdoor unit is formed into a substantially rectangular parallelepiped as described above, for example, by forming the surface on which the front decorative cover is located into a substantially square surface, the contour of the grill of the blower outlet of the blower and the makeup are made. The center point of the outline of the cover 5 with respect to the contour of the front shape does not significantly shift, and the appearance design can be improved.

Further, when the above tool 13 is used, the valve fixing plate 10
The stress applied to the valve fixing plate 10 is
Side plate upper end and the upper end 2 of the support member 20 of the blower 8
0a, the electrical component box 9, and the decorative cover 5 are fixed to the upper end of the decorative cover 5 by a fixing means such as a screw, and the left side of the electrical component box 9 is screwed to the upper end of the decorative cover 5, so It is possible to prevent the valve fixing plate 10 from being distributed and deformed. Moreover, since the valve fixing plate 10 has the protrusion formed by drawing, the deformation can be further prevented.

Next, the installation of the outdoor unit having the above structure will be described with reference to FIGS. 18 to 24. FIG. 18 is a perspective view of the upper surface cover 6 as viewed from the upper left of the rear surface. FIG. 19 is a simplified cross-sectional view illustrating how the top cover 6 is attached.
21 to 23 are perspective views showing the installation state of the respective embodiments, and FIG. 24 is a schematic view showing the installation space of the embodiment and the conventional installation space.

As shown in FIG. 18, the lower end corners of the recess 6e for inserting the refrigerant pipe 12 are rounded so that the upper surface cover 6 is engaged on the left side as shown in FIG. It is possible to prevent the refrigerant pipe 12 from being caught when the right side is rotated by using the joint portion as a fulcrum and is attached to the decorative cover 5.

According to the outdoor unit 1 having the construction in which the connection valve 11 is provided on the upper surface side of the outdoor unit of the above embodiment, the outdoor unit 1 can be installed close to the building as shown in FIGS. 21 to 23. it can. That is, FIG. 21 is a perspective view showing that the right side of the outdoor unit 1 can be installed close to the building, and the gap dimension L ₁ between the outdoor unit 1 and the balcony, which is the structure of the building.
As shown in FIG. 24, it is possible to greatly reduce the gap size L _{4 of the related art in} which the connection valve is provided on the side surface of the outdoor unit. Compared with the conventional gap size L ₄ of 200 mm, the gap size L ₁ of the embodiment is 100 mm, which is 1 /
It is 2.

The gap dimension L ₂ between the outdoor unit 1 and the wall of the building is 50 mm, which is the same as the conventional one. This gap dimension L ₂
The reason why the gap dimension L ₁ is larger than that is that the air flowing into the gap having the gap dimension L ₁ also flows into the rear side in addition to the air sucked into the side air suction grille 5b. .

Further, since the outdoor unit 1 of the embodiment does not have a connecting valve on the side surface, the dimension in the width direction is reduced accordingly, and the window of the building is not blocked as shown in FIG. Become. That is, the size of the embodiment of the outdoor unit 1 is 595.
mm, and the dimension 695 mm (about 700 mm) obtained by adding 100 mm to the above-mentioned gap dimension L ₁ is not larger than 700 mm to 800 mm which is a large dimension between the balcony and the window of a general residential building, so It can be prevented from blocking.

FIG. 22 is a perspective view showing an example in which the right side surface of the outdoor unit 1 is installed with a gap dimension L ₁ between it and the wall of the building. In this case, the size of the gap between the left side surface of the outdoor unit 1 and the veranda is 100 mm, which is obtained by subtracting the above 695 mm (about 700 mm) from 800 mm of the depth of a general veranda,
The dimensions required for air inflow can be secured. Depending on the veranda, there are some that are larger than 800 mm, but the gap size L of the conventional outdoor unit equipped with a connection valve is L
_{No. 4} is an example of installation that cannot be installed on a general veranda because the depth dimension of the veranda is 900 mm because it is 100 mm larger than the gap size L ₁ of the embodiment.

According to the installation example of FIG. 22, the door can be installed without covering a part of the door with the outdoor unit 1 even when the distance from the door to an object such as a veranda is extremely small (for example, 300 mm). . Although FIG. 22 is an example of installation on the left side of the veranda, it can be installed on the right side of the veranda as well. FIG. 23 is a perspective view in which the back surface of the outdoor unit 1 is installed between the wall of the building on the left side of the veranda with a gap dimension L ₂ .

In this case, when the refrigerant pipe 12 for connecting to the indoor unit is connected to the connection valve 11, the refrigerant pipe 1
It is advisable to bend the refrigerant pipe 12 in advance so that the refrigerant pipe 12 can be arranged along the inclined portion 6a of the upper surface cover 6 that is attached after attaching 2 to the connection valve 11. As a result, the refrigerant pipe 12 can be prevented from projecting upward from the upper surface of the outdoor unit 1, so that the refrigerant pipe 12 becomes inconspicuous, and the appearance fusion with the building is improved. Further, by installing the refrigerant pipe 12 along the inclined surface 6a as described above, it is possible to prevent the refrigerant pipe 12 from projecting upward from the upper surface of the outdoor unit 1. Therefore, two outdoor units 1 are stacked and installed. It is possible to

As described above, in the embodiment, since the connecting valve is not on the side of the side wall, the installation space can be saved, and the external appearance can be made into a rectangular parallelepiped, so that the design to be integrated with the building is easy.

In the above embodiment, the connection valve 11 is provided so as to be inclined. However, as shown in the enlarged cross-sectional view of the upper right portion of the outdoor unit in FIG. The rotation direction of the conduction valve (not shown) and the cap nut may be set to be horizontal or vertical.

That is, as shown in FIG. 25, the connection valve 1
When the direction of rotation of the cap nuts, which are the operation parts of 1a 'and 11b', is set horizontally, the electrical equipment box 9 interferes when the cap nuts are turned by a tool, and the operation rotation angle of the tool is about 90 degrees. However, the workability is better than that of the conventional case where the connection valve is provided on the side surface. Moreover, since the upper surface is open, the workability in connecting the refrigerant pipe 12 is extremely good as in the embodiment shown in FIG. It should be noted that an L-shaped tool, which has become widespread in recent years, may be used in place of an extremely general straight-line general-purpose tool that has been in general use for a long time as shown in FIGS. 1 and 6. For example, as in the embodiment of FIG. 6, the operation rotation angle is about 150 degrees to 180 degrees, and the workability is extremely good as in the embodiment of FIG.

As shown in FIG. 26, the refrigerant communication valve 1
When the rotation directions of the operation parts 1a "and 11b" are provided vertically, the electric component box 9 does not interfere when the operation part is rotated by the tool, and the operation rotation angle of the tool becomes about 120 degrees, and the connection is made. The workability is significantly better than that of the conventional valve on the side. The workability in connecting the refrigerant pipe 12 is extremely good as in the embodiment shown in FIG. 6 and the embodiment shown in FIG.

The drawing of the valve fixing plates 10 'and 10 "shown in FIGS. 25 and 26 is performed in the same manner as the convex portions 10c and 10f of the valve fixing plate 10 shown in FIG. A portion is provided, and the size of the convex portion is such that it does not interfere with the operation and rotation of the screw 12a for mounting the refrigerant pipe 12 with a tool, as in the case shown in FIG. .

As described above, according to the above-mentioned embodiment, many effects can be obtained, and the typical effects are listed below. Since the connection valve 11 is provided on the upper surface, compared to the conventional case where the connection valve is provided on the side surface,
Installation work of the refrigerant pipe 12 and the connection valves 11a, 11
b, 11a ', 11b', 11a ", 11b" removal and installation work of the cap nut 11c, and after the cap nut 11c is removed, the refrigerant conduction operation valve provided therein is rotated to open and close. Since the operation work can be performed on the upper surface side of the outdoor unit, there is no need to work in a cramped state, and reliable and efficient work can be performed.

Since the connection valve 11 is tilted, the tool 1
Since the rotation locus of 3 is not applied to the electric component box 9 and the work using a general-purpose tool that is generally widely used can be performed without being greatly affected by either the electric component box 9 or the wall even near the wall, Workability is good and there is no need to prepare special tools.

In the embodiment in which the valve fixing plate 10, the heat exchanger 3, the support member 20 of the blower, and the electric component box 9 are constituent members for ensuring the strength of the box body of the outdoor unit 1, a reinforcing member for the box body is different. It is not necessary to prepare the parts, the size can be reduced, and the number of parts to be assembled and the assembly time can be shortened.

A convex portion is provided on a part of the valve fixing plate 10 and an inclined portion is provided so that the side surface side of the outdoor unit 1 is lowered, and the connecting valve 11 attached to this inclined portion is substantially perpendicular to the inclined portion. Attached to the refrigerant pipe 1
2 and the mounting of the connection valve 11 to the valve fixing plate 10 is ensured, and the mounting height of the connection valve 11 is suppressed. As a result, the height dimension of the space between the upper end of the heat exchanger 3 and the top cover 6 can be reduced.

The valve fixing plate 10 is formed by drawing a metal plate to enhance the strength of the valve fixing plate itself. The valve fixing plate 10 is attached to the upper end of the side surface of the heat exchanger 3 and is attached to the rear surface of the heat exchanger 3. The connection valve 11 is attached to the hooked support member 20 so as to jointly increase the connection strength between the components, and the connection valve 11 is attached to the convex portion of the valve fixing plate 10. The valve fixing plate 10 when the refrigerant pipe 12 is connected or otherwise
Since the external force applied to the heat exchanger 3 and the support member 20 are dispersed, the strength against the external force can be secured without the need for a reinforcing member.

[0079]

As described above, according to the present invention, since the connection valve is provided on the upper surface of the outdoor unit, as compared with the conventional case where the connection valve is provided on the side surface, the work of installing the refrigerant pipe and the refrigerant The operation work of the connection valve after installing the pipe can be done on the upper surface side of the outdoor unit that can secure a large space, and it is not necessary to work in a cramped state,
You can work reliably and efficiently.

Further, since the connecting valve is provided on the upper surface side of the outdoor unit, the protruding size of the connecting valve and the working space necessary for working are eliminated on the side surface.
The outdoor unit can be installed close to the side of the building, and since the connecting valve is not on the side as in the conventional case, the installation space can be saved.

Since the valve fixing plate, the heat exchanger, the support member of the blower, and the electrical component box were used as the structural members for ensuring the box strength of the outdoor unit, the reinforcing member for the box body should be prepared as a separate component. There is no need for this, and it is possible to reduce the size and reduce the number of parts to be assembled and the assembly time.
