Description

  The present invention relates to an air conditioner, and more particularly to a structure that suppresses vibration of a fan motor that drives a blower fan and improves maintainability of an electrical component.

  The conventional air conditioner includes an electrical component module in which the electrical components are unitized, and improves the workability of the assembly. As a result, the electrical component is attached to the first mounting portion and the fan motor and the drive motor, respectively. An electrical box having a second mounting portion, and a first substrate parallel to the rear surface of the fan motor, which is detachably attached by sliding back and forth on the electrical box, and a second board in the vicinity of the drive motor. There has been disclosed a unit formed as an electrical component module that is configured by electrical lids each provided with a substrate and divided into left and right (see, for example, Patent Document 1).

However, in the air conditioner configured as described above, the fan motor that drives the blower fan is fixed in the same direction (thrust direction) as the drive shaft of the fan motor, so that vibration during driving can be suppressed. It was difficult.
That is, since it is necessary to press strongly when fixing in the thrust direction, there is a possibility that the anti-vibration effect by the anti-vibration member may be reduced. For example, the thickness of the anti-vibration member is configured by pressing in the radial direction. It was desired to be able to take enough.

  In addition, since the first substrate parallel to this is provided on the back surface of the fan motor so as to oppose, the left and right width dimensions of the unitized electrical component module are increased, There was a problem that the electrical component may be affected by noise.

  Furthermore, since the drive motor for driving the right and left wind direction plates and the diffuser is provided outside the electrical box, wiring work is required at the time of assembling work on the production line, and workability is not good. In addition, since the electrical board and the terminal board are arranged on the electrical cover, wiring work and maintenance in the electrical component module become complicated, and all connections between the wiring and the electrical board must be removed. There was a problem that the electrical cover could not be removed.

FIG. 8 is an exploded perspective view, and FIG. 8 is a perspective view of the electrical box as viewed from the drive shaft side of the fan motor.

  As shown in the drawing, the air conditioner according to the present invention is provided with a heat exchanger 6 and a blower fan 7 in an air passage connecting the suction port 1 and the air outlet 2, and the support port 3 a is provided at the air outlet 2. Left and right wind direction plates 3 pivotally supported by the shaft, a vertical wind direction plate 4 pivotally supported by the support shaft portion 4a, and a diffuser 5 pivotally supported by the support shaft portion 5a. Is provided.

  On the sides of the heat exchanger 6 and the blower fan 7, there are a fan motor 8 that drives the blower fan 7, a drive motor 9 that drives the left and right wind direction plates 3 and the diffuser 5, and an upper electrical box 10a. And a lower electrical box 10b, and an electrical part having a display case 14 having an electrical board 12, a terminal board 13, and a display window 14a for displaying operation information. 15 is provided.

  The heat exchanger 6 and the blower fan 7 are attached to a casing A constituting the air passage, and the electrical component 15 is attached to one side of the casing A. That is, the electrical box 10 is attached to one side of the casing A shown in FIG. 2B by the front and rear attachment portions B shown in FIG. 8, and the electrical cover 11 shown in FIG. It is configured to be.

  The front and rear mounting portions B are arranged such that the front mounting portion B is lower than the rear mounting portion B, and thus the air conditioner is installed on the wall surface. However, the electrical box 10 can be easily removed.

  With the above configuration, after the air sucked from the suction port 1 is heat-exchanged by the heat exchanger 6, the air is sent to the outlet 2 by the blower fan 7. The left and right wind direction plates 3 are provided and deflected reciprocally about the support shaft portion 3a by the drive motor 9, and the reciprocating rotation is performed about the support shaft portion 4a. The vertical wind direction is deflected by the vertical wind direction plate 4.
