Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an outdoor unit of an air conditioner, and more particularly, to an improved structure for expanding the machine room space.
[0002]
[Prior art]
FIG. 3 shows a method of expanding the back of the machine room in an outdoor unit of a conventional air conditioner. In the figure, 1 is a machine room, and includes a partition plate 2, a front panel 3, and side and back integrated. The L-shaped panel 4 is surrounded. Reference numeral 5 denotes an expansion space provided on the back surface of the machine room 1 and is formed by drawing the L-shaped panel 4. 6 is a compressor disposed in the machine room 1, 7 is a fan disposed in the blower room 8, 9 is a heat exchanger, 10 is an outdoor unit fixing leg, 11 is a building wall, and 12 is a building. It is a necessary clearance dimension between the outdoor unit and the outdoor unit.
[0003]
The outdoor unit of the air conditioner has a complicated refrigerant circuit year by year. In order to store the refrigerant circuit in the machine room 1, the expansion space portion 5 is provided on the back surface of the machine room 1 as described above.
[0004]
[Problems to be solved by the invention]
In the conventional machine room expansion structure of an outdoor unit of an air conditioner, a part of the outer L-shaped panel 4 is expanded only by drawing, so that the space for storing the refrigerant circuit that is becoming more and more complicated every year is the limit. there were. In addition, when the expansion space 5 and the outdoor unit fixing leg 10 are wrapped, there is a problem that fixing work is difficult because the fixing tool does not enter from the upper part, and there is a necessary gap size between the building and the outdoor unit when installing the outdoor unit. It was difficult to measure, and there was a problem that it was installed without securing a sufficient rear space.
[0005]
The present invention has been made to solve the above-described problems, and can secure a sufficient machine room space for storing a refrigerant circuit that is becoming more and more complicated year by year, and can prevent transmission of sound from the machine room at low cost. It aims at obtaining the outdoor unit which can do.
It is another object of the present invention to provide an outdoor unit that can sufficiently secure a machine room space for storing a refrigerant circuit by utilizing the back of the machine room.
It is another object of the present invention to facilitate the workability of fixing the outdoor unit fixing legs.
It is another object of the present invention to facilitate the fixing workability of the outdoor unit fixing legs without wrapping the outdoor unit fixing legs and the extended portion even when the entire rear surface of the machine room is expanded.
It is another object of the present invention to make it easier for an installation operator to measure the required gap size at the rear, and to prevent mistakes that cause installation without securing sufficient rear space.
[0006]
[Means for Solving the Problems]
An outdoor unit of an air conditioner according to the present invention includes an outdoor unit main body, a machine room provided on a side portion of the main body, a compressor on the front side, and a refrigerant pipe on the back side, and a rear side of the machine room And an expansion space portion for storing a refrigerant circuit formed by forming a shell sheet metal member constituting the machine room into a box shape, and plastic upper and lower covers that close the upper and lower openings of the expansion space portion The outdoor unit main body includes a top plate, and the top plate covers the upper opening of the machine room that is not covered with the blower chamber and the upper cover.
[0008]
Also, an outdoor unit fixing leg for fixing the outdoor unit is provided, and the expansion space and the outdoor unit fixing leg are arranged so as to be shifted from above so that a leg fixing tool can be inserted.
[0009]
In addition, a blower chamber containing a blower or the like is provided on the side of the machine room, and an outdoor unit fixing leg is disposed below the back of the blower chamber.
[0010]
In addition, the back surface of the expansion space portion is shaped to be flush with the side surface .
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings. 1 and 2 are views showing Embodiment 1 of the present invention, in which FIG. 1 is a partial cross-sectional view showing a machine room space, and FIG. 2 is a perspective view of an outdoor unit as viewed obliquely from the rear. In FIG. 1, reference numeral 1 denotes a machine room, which is surrounded by a partition plate 2, a front panel 3, and an L-shaped panel 4 that is an outer sheet metal member integrated with a side surface and a back surface. Reference numeral 5 denotes an expansion space provided on the back surface of the machine room 1, and the L-shaped panel 4 is formed into a box shape by bending.
Further, 6 is a compressor disposed in the machine room 1, 7 is a fan disposed in the blower room 8, 9 is a heat exchanger, 10 is an outdoor unit fixing leg, 11 is a building wall, and 12 is a building and outdoor. This is the required gap size with the unit.
[0012]
In FIG. 2, reference numerals 13 and 14 denote upper and lower covers for closing the upper gap 15 and the lower gap 16 of the expansion space portion 5, and are formed in accordance with a sheet metal shape to prevent intrusion of rain.
[0013]
By forming the L-shaped panel 4 into a box shape by bending and attaching the upper and lower covers 13 and 14 on the back side of the machine room 1, the expanded space part 5 is provided, so that a wider machine room can be obtained. It is possible to secure a more complicated refrigerant circuit.
[0014]
Since the upper cover 13 and the lower cover 14 are far from the compressor 6 and have little transmitted sound, they can be made of plastic and are inexpensive.
[0015]
Since the outdoor unit fixing leg 10 is arranged below the blower chamber 8 and the expansion space portion 5 is shifted, the leg fixing tool can be inserted from above.
[0016]
The extension space portion 5 provided on the back surface of the machine room 1 is extended from the side surface so that the distance from the side surface to the outdoor unit and the wall of the building can be measured, and the rear space is ensured.
[0017]
【The invention's effect】
In the outdoor unit of an air conditioner according to the present invention, by providing an expansion space portion on the back surface of the machine room, a wider machine room can be secured than before, and more complicated refrigerant pipes can be accommodated.
[0018]
Moreover, since the upper and lower covers are made of plastic, it is inexpensive.
[0019]
Moreover, since the expansion space part of the machine room and the outdoor unit fixing leg are arranged so as to be shifted, it is easy to insert the leg fixing tool.
[0020]
In addition, since the extended space portion of the machine room is extended from the side surface to the same plane, the distance from the side surface to the outdoor unit and the wall of the building can be measured, and the rear space is ensured reliably.
