By adjusting both or one of the angles α, the angle of the receiving element 53 or the relative angle between the receiving element 53 and the transmitting element 55 can be changed, and space can be saved. .

  As shown in FIGS. 12 and 13, the transmitter / receiver 50 having such components is positioned and locked by inserting guide pins 56 e of the board coupling component 56 into guide holes (not shown) of the transmission board 54. The claw 56f is locked and fixed in the locking hole 54a of the transmission board 54. Further, the locking piece 56g provided on the board coupling component 56 is locked to the upper surface of the receiving board 52, and the protrusion 56h is fitted into the notch 52a of the receiving board 52, so that the receiving board 52 and the transmitting board are fitted. 54 is temporarily fixed to the board coupling component 56.

  As shown in FIG. 14, the reception board 52, the transmission board 54, and the board coupling component 56 integrated in this way are installed on the main body part 57a of the board holding part 57, and the lid part 57b is attached by the hinge part 57c. It turns around and surrounds them, and is held between the main body portion 57a and the lid portion 57b. At this time, the receiving claw 57e provided on the lid portion 57b engages with the engaging portion 57d provided on the main body portion 57a, so that the receiving substrate 52, the transmitting substrate 54, and the substrate coupling component 56 are attached to the substrate holding component 57. It is securely held and fixed. Further, the receiving element 53 and the transmitting element 55 of the transceiver 50 are exposed from the lid portion 57b.

  The electrical component box 30 in which the board holding component assembly 31 and the power line guide component 41 are integrally coupled as described above is provided on one side of the base 2 as shown in FIGS. 6, 15, and 16. The housing 3 is mounted on the front (front side). At this time, the receiving element 53 and the transmitting element 55 of the transmitter / receiver 50 provided on the power line guide component 41 of the electrical component box 30 are connected to the back of the transmitter / receiver cover 22 through the opening 21 in the transmitting / receiving unit 20 of the housing 3. On the side (rear), it is inclined obliquely forward.

That is, as shown in FIGS. 16 and 17, the transmitter / receiver 50 integrated with the electrical component box 30 and attached to one side of the base 2 is located on the back side of the opening 21 of the housing 3. The receiving element 53 and the transmitting element 55 are exposed, and the front surface of the receiving element 53 and the transmitting element 55 is covered by attaching the transmitting / receiving unit cover 22 to the opening 21.
For example, when the indoor unit 1 is set on a vertical wall surface, the transmitter / receiver 50 is located near the bottom surface of the indoor unit 1, and the receiving element 53 is inclined to the front side, for example, about 45 ° with respect to the vertical line. The transmitting element 55 is inclined to the front side with respect to the receiving element 53.

  Now, for example, when an operation signal is sent from the obliquely lower side of the indoor unit 1 to the transmitter / receiver 50 by the remote controller, the operation signal passes through the transmitter / receiver cover 22 and reaches the receiving element 53, and the air conditioner starts operation. To do. The operating condition of the air conditioner is transmitted from the transmission element 55 to the remote control.

At this time, since the receiving element 53 is disposed obliquely forward in the vicinity of the bottom surface of the indoor unit 1, it is possible to reliably receive an operation signal from the remote controller. Moreover, the signal regarding the operating condition of the air conditioner can be reliably transmitted from the transmitting element 55 to the remote controller, and both signals do not interfere with each other.
In addition, as shown in FIG. 17, if the recessed part 23 with a substantially triangular cross-section is provided in the position facing the receiving element 53 of the transmission / reception part cover 22, for example, if the plate | board thickness of the part is made thin, it will separate from the distant position. Since a slightly attenuated remote control operation signal can be easily transmitted, a signal from the remote control can be received more reliably.

  According to the present invention, the transmitter / receiver 50 is configured such that the receiving board 52 on which the receiving element 53 is mounted and the transmitting board 54 on which the plurality of transmitting elements 55 are mounted on different boards, and the board coupling component 56 temporarily Since these are joined and fixed integrally by the board holding component 57, the whole can be made compact, and this eliminates restrictions on the mounting space of the indoor unit 1 of the air conditioner. It is possible to secure the reception and transmission areas, and the degree of freedom in design can be increased.

Further, the mounting angle of the receiving element 53 or the relative angle between the receiving element 53 and the transmitting element 55 is changed by changing the height of the board coupling component 56 and / or the angle of the mounting portion 56 a of the receiving board 52. Therefore, it is possible to easily cope with the mounting space of the transmitter / receiver provided in the indoor unit 1 and to save space.
Further, as described above, the relative mounting angle between the receiving element 53 and the transmitting element 55 can be changed, so that interference between the received signal and the transmitted signal can be prevented.
