  As shown in the external perspective view of FIG. 1, the outdoor unit of an air conditioner according to the present invention includes a base 1 (described later) provided with a pair of left and right legs 1 a and an outer trunk covering the base 1. The outer body includes a front panel 2 provided on the front surface of the base 1, a left panel 25 described later provided on the left side of the base 1, a right panel 3 provided on the right side of the base 1, and the front panel 2 and the right side. It consists of the panel 3 and the top plate 4 which covers the upper surface of a left side panel. The right panel 3 is provided with a handle 7 at the top, and provided with an opening 3a that faces a terminal block 15 described later and is connected to the terminal block 15 and through which a wiring 23 from an indoor unit (not shown) and a wiring 24 described later are inserted. ing. A pipe cover 6 can be detachably attached to the right panel 3 so as to cover the opening 3a. A circular air outlet 5 is formed on one side of the front panel 2, and a fan guard 5 a is attached so as to cover the air outlet 5.

  Next, the internal configuration will be described. As shown in FIG. 2, the base 1 constituting the bottom surface is partitioned into a machine chamber 9 and a heat exchange chamber 10 by a partition plate 8. A compressor 11 and an accumulator 12 are arranged in the machine room 9, and an outdoor heat exchanger 16 and a blower fan 18 formed in an L shape are arranged in the heat exchange chamber 10. The outdoor heat exchanger 16 includes a large number of fins arranged in parallel and heat transfer tubes arranged in a meandering manner so as to be orthogonal to the fins, and the blower fan 18 is a support base 17 erected on the base 1. It is pivotally supported by a fan motor (not shown) attached to the motor.

  An electrical unit 13 having a control board 13a, which will be described later, is arranged above the machine room. A terminal block holder 14 is attached to a lower part of the electrical unit 13 and faces the opening 3a. A terminal block 15 is supported on the surface 14 a of the terminal block holder 14. The wiring 23 from the indoor unit is connected to the terminal block 15 through the opening 3a, and then connected to the control board 13a by an internal wiring (not shown).

  Next, attachment of the auxiliary substrate 19 will be described with reference to FIG. The terminal block 15 is supported on the front surface 14 a of the terminal block holder 14, while the auxiliary substrate 19 is attached to the back surface 14 b of the terminal block holder 14. A lead wire 21 is led out from the auxiliary board 19 attached to the back surface 14b and connected to the control board 13a. On the other hand, the wiring 24 is inserted through the opening 3a and connected to an external device disposed indoors. Yes.

  When it is necessary to control the air conditioner by an external device, the auxiliary board 19 is mounted on a mounting plate 22 (to be described later) of the terminal block holder 14 during the installation of the air conditioner, and is connected to the control board 13a by the lead wire 21. In addition to being connected, the wiring 24 connects to an external device (not shown) disposed indoors. Thereby, for example, the power consumption of the air conditioner is controlled by an external device, and can be adapted to the restriction of power restriction by the government.

  Substrate holders 20 made of a resin material are attached to the four corners of the auxiliary substrate 19. After the auxiliary substrate 19 is attached to the attachment plate 22 as an attachment portion joined to the back surface 14 b of the terminal block holder 14 by the substrate holder 20, As described above, the lead wire 21 led out from the auxiliary board 19 is connected to the control board 13a, and the wiring 24 from the auxiliary board 19 is connected to an external device through the opening 3a. .

  Next, the mounting structure of the auxiliary board 19 will be described in detail. As described above, the mounting plate 22 made of sheet metal is joined to the back surface 14b of the terminal block holder 14. As shown in FIG. 4, the mounting plate 22 is formed in a trapezoidal shape, a pair of base portions 22 c that are joined to the back surface 14 b of the terminal block holder 14 by spot welding, and an inclined portion that is inclined and raised from the base portion 22 c. 22b and a rectangular holding portion 22a formed continuously from the inclined portion 22b and having four insertion holes 22d.

  The substrate holder 20 made of a resin material attached to the four corners of the auxiliary substrate 19 is formed in an L shape having a claw portion 20a for suppressing the corner portion of the auxiliary substrate 19, and corresponds to the insertion hole 22d of the attachment plate 22. A plurality of mounting legs 20b made of a resin material having flexibility are provided.

  By inserting the mounting leg 20b of the substrate holder 20 supporting the auxiliary substrate 19 into the insertion hole 22d formed in the holding portion 22a of the mounting plate 22, the mounting leg 20b is fixed to the holding portion 22a. Yes. Thereby, the auxiliary substrate 19 can be easily mounted in the outdoor unit without requiring a complicated operation such as screwing.

  If it is going to arrange | position the auxiliary | assistant board | substrate 19 in the surface 14a of the terminal block holder 14, it will arrange | position with the terminal block 15 and it is necessary to widen the terminal block holder 14. FIG. For this reason, an outdoor unit housing | casing becomes large and there exists a possibility of hindering compactization of an outdoor unit housing | casing. According to the present invention, by arranging the auxiliary substrate 19 on the back surface 14b of the terminal block holder 14, the outdoor unit housing can be made compact by effectively using the dead space, while the installation work of the air conditioner is performed. The mounting operation of the auxiliary board 19 performed at this time can be performed without disassembling the electrical unit 13, and the burden of the mounting operation can be reduced.
