DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art FIG. 3 shows an example of an outdoor unit of a conventional separation type air conditioner. The interior of the casing 1 of the outdoor unit 100 is divided into right and left by a partition plate 2, and a machine room 3 is formed on the right side and a heat exchange room 4 is formed on the left side.

In the heat exchange chamber 4, an L-shaped heat exchanger 9, a blower fan 10, a motor 14, and the like are arranged. The L-shaped heat exchanger 9 has an air inlet 11 formed on the back surface 1a of the casing 1.
And an air inlet 12 formed on the left side surface 1b. The blower fan 10 is disposed so as to face an air outlet 13 formed in the front surface 1c of the casing 1.

In the machine room 3, in addition to the compressor 5, a control box, an accumulator, a discharge muffler, a four-way switching valve, a receiver, an expansion valve, and the like (not shown) are provided.

When the blower fan 10 is driven to rotate by a motor 14, outside air is drawn into the heat exchange chamber 4 from the air intakes 11 and 12, and exchanges heat with the refrigerant in the process of flowing through the heat exchanger 9 to rise. After the temperature is lowered or heated, the air is blown by the blower fan 10 and discharged from the outlet 13 to the outside.

[0006] The compressor 5 has three mounting legs 5A, 5B and 5C, and these mounting legs 5A, 5B and 5C are arranged as shown in FIG.
It is supported on a vibration isolator 16 fitted to a stud bolt 15 erected on the bottom plate 1d. The stud bolt 15 penetrates a bolt hole 17 formed in the mounting legs 5A, 5B, and 5C, and a nut 18 is screwed on the tip of the bolt.
When transporting 100, the mounting feet 5A, 5B, and 5C
To prevent them from getting out.

[0007]

In the conventional air conditioner described above, when the compressor 5 is removed for repair, replacement, etc., the retaining nuts 18 of the mounting legs 5A, 5B located in front of the machine room 3 are provided. Although it can be easily removed, it is extremely difficult to remove the retaining nut 18 of the installation leg 5C located at the back of the machine room 3 because the working space is narrow.

SUMMARY OF THE INVENTION The present invention was invented to solve the above problems, and has as its gist, by partitioning Ri by an internal vessel housing the partition plate
A machine room is formed on one side of the partition plate and heat is applied to the other side.
Forming a replacement chamber, accommodating the compressor into the interior of the machine room
In the air conditioner, the compressor is discharged from the lower part
At least three or more mounting feet extending morphism direction provided which
The mounting legs respectively penetrate stud bolts erected on the bottom plate of the machine room and are supported on a vibration-proof material fitted thereto with vibration isolation , and the partition plate is detachable. Above the mounting feet only
A retaining bracket for preventing the attached leg from coming out of the stud bolt is provided on the partition plate, and
Prevents other mounting feet from falling out of the stud bolt
Screw on the stud bolt to secure
An air conditioner characterized by being mounted .

The bracket can be formed integrally with the partition plate.

[0010]

In the present invention, when the compressor is to be removed, the bracket provided on the partition plate is removed from above the mounting leg located at the back of the machine room by removing the partition plate. From the stud bolt.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. A nut is not screwed into the tip of the stud bolt 15 that penetrates the mounting leg 5C located at the back of the machine room 3, and this mounting leg 5C
A retaining bracket 20 is provided on the partition plate 2 so as to be located slightly above the partition plate 2. The other configuration is the same as that of the conventional one shown in FIG. 3, and the corresponding members are denoted by the same reference numerals.

However, even if the outdoor unit shakes during transportation or the like, the nuts 18 are screwed at the ends of the stud bolts 15 penetrating the mounting legs 5A and 5B of the compressor 5, respectively. The legs 5A and 5B are prevented from coming out of the stud bolt 15 by the nut 18. Also,
The mounting leg 5C is prevented from falling out of the stud bolt 15 by a retaining bracket 20 located slightly above the mounting leg 5C.

When the compressor 5 is to be removed, the nut 18 is removed from the tip of the stud bolt 15 penetrating the leg with legs 5A and 5B, the partition plate 2 is removed, and the retaining bracket is removed.
When the 20 is detached from above the leg 5C, the compressor 5 is lifted and the mounting legs 5A, 5B, 5C are respectively stud bolts 15C.
Compressor 5 can be removed by extracting from compressor 5.

As shown in FIG. 2, the bracket 21 can be cut and raised from the partition plate 2 and can be formed integrally therewith. In this case, a hole 23 where the bracket 21 is cut and raised is formed.
May be closed by attaching a wind shield 24 to the partition plate 2.

[0015]

According to the present invention, the outdoor unit is transported.
Also a time like this is reeling located at the back of the machine room mounting legs its
The retaining brackets located above the studs prevent the stud bolts from coming out , and the other mounting feet
This stud is secured by a retaining nut screwed onto the bolt.
He is prevented from getting out of the bolt. Also, when removing the compressor, it is only necessary to remove the retaining bracket by removing the partition plate, and remove the nut screwed on the stud bolt that penetrates the mounting leg located in the back of the machine room as in the past. Since there is no need, the compressor can be easily removed.
