Abstract

PROBLEM TO BE SOLVED: To eliminate contact of a lead of a fan motor with a reactor by a method wherein an upper part of an electric component is mounted on a partition plate through a fixed plate and a groove is formed to place and house the lead of the fan motor on the fixed plate. SOLUTION: An electric component box 17 is placed on a stage part 15 of a partition plate 11 to divide a machine chamber 14 housing an air path 10 running through an outdoor heat exchanger 5, a compressor and the like. The electric component box 17 is mounted on an auxiliary plate part 18 of the partition plate 11 through a fixed plate 27. A control substrate 22 in the electric component box 17 is provided with a connector 23 for connection to a lead 21 of a fan motor. A U-shaped groove 30 is formed on the fixed plate 27 positioned between the auxiliary plate part 18 and the electric component box 17 and above the reactor 19 there. The lead 21 of the fan motor is housed into the groove 30. This keeps the lead 21 from being slackened to eliminate contact with the reactor below it thereby enabling protection securely from the reactor generating high temperature heat.

There is a problem that the slack 21 easily contacts the reactor 19.

Therefore, an object of the present invention is to solve the above problems and provide an outdoor unit of an air conditioner which does not come into contact with a reactor when guiding a fan motor lead wire to an electric parts box.

[0010]

In order to achieve the above object, the invention of claim 1 mounts an electric parts box on a partition plate that partitions an air passage passing through an outdoor heat exchanger and a machine room accommodating a compressor and the like. In the outdoor unit of the air conditioner, in which the upper part of the electric component box is installed on the partition plate via the fixing plate, and the electric motor is connected to the fan motor lead wire from the outdoor fan, the fan motor is attached to the fixing plate. It is an outdoor unit of an air conditioner in which a groove for mounting and accommodating a lead wire is formed.

The invention according to claim 2 is the outdoor unit for an air conditioner according to claim 1, wherein the groove is formed in a U shape, and a hole for draining water is formed in an intermediate portion of the groove.

An invention according to claim 3 is the outdoor unit for an air conditioner according to claim 1, wherein the groove is formed to be inclined.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

First, the basic construction of the outdoor unit of the air conditioner of the present invention is as described with reference to FIG.

Now, in FIG. 1, an electric component box 17 is placed on a step portion 15 of a partition plate 11 for partitioning an air passage 10 passing through the outdoor heat exchanger 5 and a machine chamber 14 accommodating the compressor 12 and the like, and its electric The component box 17 is installed via a fixed plate 27 attached to the auxiliary plate portion 18 of the partition plate 11. The fixing plate 27 is provided so as to be mounted on the top surfaces of the outdoor heat exchanger 5 and the partition plate 11, is fixed to the auxiliary plate portion 18 of the partition plate 11 with screws 28, and has a front edge 27a for electrical components. It supports the box 17.

An inverter device 16 and the like are accommodated in the electric component box 17, and a control board 22 in the electric component box 17 is provided with a connector 23 for connecting to a fan motor lead wire 21.

A U-shaped groove 30 is formed in the fixed plate 27 between the auxiliary plate portion 18 and the electric component box 17 and on the reactor 19 of the pipe, and a fan is formed in the groove 30. The motor lead wire 21 is accommodated. The partition plate 11 is formed with a cutout groove 31 for accommodating the U-shaped groove 30.

The cutout groove 31 is substantially the same as the cutout groove 25 for holding the fan motor lead fixture 20 described with reference to FIG. A tie wrap tie 26 for holding the fan motor lead wire 21 is formed on the side surface of the electric component box 17.

As shown in FIG. 2, the U-shaped groove 30 has a drainage hole 32 formed in the middle thereof, and leads for preventing the fan motor lead wire 21 housed therein from coming out of the groove 30 on the left and right sides of the groove 30. The pressing piece 33 is formed. The drain hole 32 is formed so as to be located on the air passage 10 side with the partition plate 11 as a boundary.

Next, the operation of the present embodiment will be described.

A fan motor lead wire 21 from an outdoor fan (not shown) is housed in the U-shaped groove 30 of the fixing plate 27, and since there is no slack, the reactor 19 therebelow.
Reactor 19 that does not come into contact with the
Can be reliably protected from Further, even if rainwater or the like enters, it can be drained from the drain hole 32, and the lead wire 21 can be protected from water.

FIG. 3 shows another embodiment of the present invention, in which the U-shaped groove 30 formed in the fixing plate 27 is made different in depth and inclined. In this case, it is preferable that the rainwater that has penetrated by making the groove 30a on the air passage 10 side deeper than the groove 30b on the machine room 14 flow to the air passage 10 side preferably has a drain tray below the outdoor heat exchanger 5 (see FIG. (Not shown).

As described above, by inclining the U-shaped groove 30, even if water enters the groove 30, it can flow.

[0024]

In summary, according to the present invention, the fan motor lead wire is housed in the U-shaped groove of the fixing plate and does not come into contact with the reactor thereunder because slack does not occur. Can be reliably protected from the reactor.
