Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to an outdoor unit of an air conditioner provided with a frequency converter.

(Prior Art) Some air conditioners are of a separate type that is divided into an indoor unit and an outdoor unit.
The interior of the outdoor unit is divided into a machine room and a blower room by a partition plate, and the machine room is equipped with a compressor, and the blower room is equipped with a condenser, an outdoor blower, and the like. In such a separate air conditioner, the rotational frequency of the compressor is controlled in accordance with load fluctuations of the indoor unit. In that case, the outdoor unit is provided with a frequency converter.

By the way, in order to install a frequency converter in an outdoor unit, it is held and fixed to a partition plate that separates the interior of the outdoor unit with a portion thereof protruding into the blower room. That is, by making a part of the frequency converter protrude into the blower room, the frequency converter is cooled by the air flow flowing through the blower room.

Conventionally, in order to perform maintenance and inspection on the frequency converter, the top panel of the main body of the outdoor unit was removed to open the top surface, and then the lid of the frequency converter was removed and the inside was inspected. was. However, if multiple outdoor units are installed in parallel or if a snow protection duct is installed to protect the air outlet cabinet formed on the top panel from snow accumulation, the top panel must be removed to perform maintenance and inspection of the frequency converter. That becomes difficult.

Therefore, maintenance and inspection of the frequency converter is sometimes performed by removing the front panel of the outdoor unit. In that case, maintenance and inspection of the frequency converter is extremely difficult unless the frequency converter is removed from the partition plate. However, the frequency converter that has been removed from the partition plate may not be able to be placed down without removing the electrical wiring, and in such cases, the operator must carry out maintenance and inspection while holding the frequency converter in their hands. However, the workability was very poor.

(Problems to be Solved by the Invention) As described above, in the conventional outdoor unit, maintenance and inspection of the frequency converter cannot be easily performed from the front panel side.

This idea was developed based on the above circumstances, and its purpose is that when maintenance and inspection of the frequency converter is performed from the front panel side, the frequency converter removed from the partition plate can be hung in the machine room. It is an object of the present invention to provide an outdoor unit of an air conditioner that is designed to have the following characteristics.

[Structure of the device] (Means and effects for solving the problem) In order to solve the above problem, this device separates the main body of the outdoor unit into a machine room and a blower room using a partition plate. In addition, in an outdoor unit of an air conditioner in which a frequency converter is fixed to a fixed rod installed between the partition plate and a side plate of the machine room, the frequency converter is provided with a frequency converter that is connected to the partition plate. An engaging member is provided that can be detachably engaged with and held by the fixing rod when removed from the fixing rod. Thereby, the frequency converter removed from the partition plate can be hung on the fixed rod.

(Example) An example of this invention will be described below with reference to the drawings. An outdoor unit U of an air conditioner shown in FIG. 5 has a main body 1. As shown in FIG. This main body 1 is formed into a substantially box shape, and the interior thereof is separated into a machine room 3 and a blower room 4 in the front and back direction by a partition plate 2. The front side of the machine room 3 is closed by an upper front panel 5 and a lower front panel 6, which are detachable.
A compressor (not shown) is installed inside. Further, the blower chamber 4 has suction ports 7 formed on both sides and the back, and a heat exchanger 8 is disposed above the inside. Blower room 4 facing this heat exchanger 8
An air blower (not shown) is disposed on the upper part of the main body 1, and an air blowing cabinet 11 is provided on the upper panel 9 of the main body 1, which faces the air blower. Therefore,
When the blower operates, the suction port 7 of the blower room 4
The outside air sucked in from the air exchanger 8 undergoes heat exchange and is blown out from the blowout cabinet 11.

On the other hand, as shown in FIG. 4, the partition plate 2 is formed with a recess 12 which is open at the upper end. A receiving flange 13 is bent at the bottom of the recess 12. A frequency converter 14 is attached to the recess 12 to control the rotation speed of the compressor disposed in the machine room 3. In other words, the frequency converter 14 includes a box 15 with an open top surface and a fixed lid 16 that closes the rear end of the top opening of the box 15.
a and an opening/closing lid 16b which is detachably provided on the remaining part, and various control parts (not shown) are housed inside.

Side mounting members 17 are fixed to the middle portions of both sides of the box body 15 along the vertical direction, and an upper mounting member 18 is fixed to the opening/closing lid 16b in the width direction on the front side of the side mounting members 17. It is fixed along. Further, the fixed lid 16a is provided with a plate-shaped engagement member 19 having one end fixed to the rear end thereof and the other end bent in an L-shape spaced apart from the upper surface of the fixed lid 16a at a predetermined distance. . This engaging member 19 is used to suspend and hold the frequency converter 14 removed from the partition plate 2 in the machine room 3 as described later. Note that the height of the frequency converter 14 is smaller than the depth of the recess 12.

When assembling the outdoor unit U, the frequency converter 14 is dropped into the open upper end of the recess 12, and the side mounting member 17 is attached to the partition plate 2.
It is joined to the side surface of the machine room 3 side and fixed with screws 20. Further, the upper mounting member 18 is attached and fixed with a screw 22 to a fixing rod 21 which is installed between the side plates of the machine room 3 and has a substantially L-shaped cross section.
A closing member 23 having a U-shaped cross section is provided at the open upper end of 2.
are fixed at both ends to the partition plate 2 with screws 24. An upper flange 25 is bent between the lower side of the closing member 23 and the fixed lid 16a, between the side mounting member 17 and the partition plate 2, and at the upper end of the partition plate 2 toward the machine room 3 side. and the lower surface of the upper panel 9, between the receiving flange 13 and the lower surface of the box body 15, and between the closing member 23.
Packing 26 is interposed between the upper side and the lower surface of the upper panel 9 to maintain liquid tightness.

When performing maintenance and inspection on the frequency converter 14 in the outdoor unit U having such a structure, first,
After removing the upper front panel 5 from the front of the main body 1, and disconnecting the upper mounting member 18 from the fixing rod 21, the fixing rod 21 can be changed from the state shown in FIG. 6 to the state shown in FIG. Flip it so that the flat side is facing up.

Next, the closing member 23 attached to the open end of the recess 12 of the partition plate 2 is removed, and the connection between the side attachment member 17 and the partition plate 2 is removed. Then, since the frequency converter 14 becomes free with respect to the partition plate 2, the frequency converter 14 is pulled out to the machine room 3 side. And this frequency converter 14
By engaging the engaging member 19 provided on the fixing rod 21 with the fixing rod 21, the frequency converter 14 can be hung in the machine room 3 as shown in FIG. Therefore, in this state, the opening/closing lid 16 of the frequency converter 14 is closed.
Since the interior can be inspected and maintained by opening b, the work can be carried out easily. This is particularly convenient when a plurality of outdoor units U are installed in parallel or when a snow protection hood is provided on the top panel 9 and the top panel 9 cannot be easily removed. In addition, the above fixed rod 2
The frequency converter 14 is hung with the flat surface of the frequency converter 1 facing upward. Therefore, this frequency converter 1
4 can be hung in a stable state, that is, in a state where it is unlikely to swing, which also facilitates maintenance and inspection. Note that if a square pipe is used as the fixing rod 21, for example, there is no need to reverse the fixing rod 21 when hanging the frequency converter 14.
