In the outdoor unit of the air conditioner thus configured, a holder for holding the cord of the temperature sensor is rotatably provided on the back side of the electrical component box.

In order to rotatably hold the holder, a support shaft is formed on one side of the back surface of the holder, and the support shaft is rotatably supported on the back side of the electrical component box. The shaft hole is provided. In addition, a configuration is provided in which a locking portion is provided at the tip of the support shaft. Further, a slot is formed at a tip end portion of the support shaft including a locking portion. Further, at least one holding portion for holding the cord of the temperature sensor is provided on the surface of the holder.

[0006]

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is an exploded view of the configuration of an outdoor unit. The main body of the outdoor unit includes a base 1, a front panel 2 and a rear cover 3 made of synthetic resin, and a top cover 4. A compressor 5 mounted substantially at the center of the side, a heat exchanger 6 bent and formed in a substantially concave shape and arranged from the rear side of the base 1 to the left and right front;
A blower 7 provided opposite to the rear side of the heat exchanger 6
And a two-way valve 9a for connecting a metal electrical component box 8 containing electrical components on one side and connecting a refrigerant pipe to the indoor unit on the other side.
And a mounting plate 9 to which a three-way valve 9b and the like are mounted. The mounting plate 10 is fixed to the upper end of a side plate 6a provided on both sides of the heat exchanger 6, and the like. Has a temperature sensor 11 for detecting the outside air temperature extended from the inside.

As shown in FIGS. 2 and 3, the temperature sensor 11 is held by a holder 12 rotatably mounted on the rear side of the electrical component box 8, and the holder 12 is rotatable. As a means for holding the support,
In addition to the provision of the shaft 12a, a shaft hole 8a for rotatably supporting the support shaft 12a is provided on the rear side of the electrical component box 8. A locking portion 12b for preventing the shaft 12a from slipping out of the shaft hole 8a is formed at the tip of the support shaft 12a, and a slit is formed on the locking portion 12b to facilitate insertion into the shaft hole 8a. 12c is provided, and the cord of the temperature sensor 11 is provided on the surface of the holder 12.
A plurality of holding portions 12d for holding 11a are provided.

The holding member 12 thus formed is held in the left and right direction on the back side of the electrical component box 8 as shown by the broken line in FIG. 3, and the cord 11a of the temperature sensor 11 is held by the holding portion 11d. And the holder 12 is the electrical component box 8 (mounting plate 10)
After being mounted in a predetermined position, it is rotated in the vertical direction. Therefore, an accident such as the temperature sensor 11 fluctuating and being damaged during the mounting work of the electrical component box 8 (the mounting plate 10) can be prevented, and the assembling work is also facilitated. FIG.
FIG. 3 is an enlarged view of a portion related to the present invention in the outdoor unit having the components described above.
The temperature sensor 10 held on the air vent 3 of the rear cover 3
Since it is located between the heat exchanger 6 and the heat exchanger 6, the temperature of the outside air flowing through the heat exchanger 6 can be detected with high sensitivity.

[0009]

According to the outdoor unit in which the cord of the temperature sensor is held by the holder as described above, the temperature sensor can be held on the rear side of the electrical component box until the mounting of the electrical component box is completed. In addition, the quality can be improved without damaging the temperature sensor, and the electrical component box can be easily attached and detached, and the working time can be reduced.
