Since the fixed shaft 22b includes a latch mechanism, the auxiliary device 21 can be opened to the same angle as when the front panel 4 is opened upward from the housing 24 and can be held in that state. As a result, a space where the filter 11 can be removed is secured, and the filter 11 can be easily cleaned.

  An operation when the auxiliary device 21 is attached to the indoor unit 1 will be described. When the auxiliary device 21 receives an operation instruction from the indoor unit 1, the fan 25 rotates, sucks room air from the auxiliary suction port 22a, and draws the air from the auxiliary air outlet 23a toward the upper surface opening 3a of the indoor unit 1. Blow out.

  On the other hand, as described above, in the indoor unit 1, by driving the blower fan 6, indoor air is taken into the indoor unit 1 from the upper surface opening 3 a and the front opening 3 b, and the heat exchanger 5, It passes through the blower fan 6 and is blown out from the blowout port 7 through the blower passage 10.

  At this time, the air blown from the auxiliary air outlet 23a of the auxiliary device 21 is added to the air sucked from the upper surface opening 3a by the blower fan 6 of the indoor unit 1, and the amount of air blown from the indoor unit 1 is increased. The air conditioning capacity can be improved.

  In particular, in the configuration of the present embodiment, the auxiliary suction port 22a is opened in a direction substantially perpendicular to the top surface of the indoor unit 1, and the inclined portion (the indoor unit 1) of the upper surface opening 3a. Is opened so as to be opposed to the upper part of the front surface. For this reason, air can be directly blown to the inclined portion of the upper surface opening 3a. In addition, the auxiliary device 21 can blow out air in parallel above the horizontal portion of the upper surface opening (the upper surface of the indoor unit). Thereby, the suction amount of the indoor unit 1 can be increased efficiently without imposing a load on the blower fan 6, and the air conditioning capability can be increased.

  Further, since the auxiliary suction port 22a of the auxiliary device 21 is located between the upper surface opening 3a and the front surface opening 3b of the indoor unit 1, the flow of room air that the auxiliary device 21 sucks from the auxiliary suction port 22a, Since the indoor air flow sucked by the unit 1 does not interfere with each other, the amount of suction of the indoor unit can be increased efficiently, and the air conditioning capability can be increased.

  Moreover, since the air flow path of the auxiliary device 21 has a depth equivalent to the gap provided in the front grill 3 and the front panel 4, it does not become resistance to air flow in the auxiliary device 21, In addition, the auxiliary device 21 does not suck a large amount of air that interferes with the flow of air sucked from the front opening 3 b of the indoor unit 1.

  Next, the operation when the auxiliary device 21 is detached from the indoor unit 1 will be described. Since the claw 3 c provided in the indoor unit 1 has flexibility, the auxiliary device 21 can be easily detached from the indoor unit 1 by removing the fitting with the mounting hole 26 c of the auxiliary device 21.

  When the indoor unit 1 is installed in a large room, the flow rate of the air blown out from the indoor unit 1 is insufficient, and an area where air conditioned air does not reach the corner of the room may occur. Alternatively, when there is an obstacle in the room, the air conditioned air may not reach behind the obstacle.

  In such a case, as shown in FIG. 5, the user removes the auxiliary device 21 from the indoor unit 1 and installs it on the floor or the like where air conditioned air reaches. When the auxiliary device 21 is removed and placed on the floor, the auxiliary device 21 is placed upside down from the case where it is attached to the indoor unit 1 and the fixture 26 is placed downward.

That is, by rotating the fan 25 of the auxiliary device 21, the auxiliary device 21 sucks in air-conditioned air blown from the air outlet 7 of the indoor unit 1 from the auxiliary air inlet 22 a, and from the auxiliary air outlet 23 a, It can blow out in a direction different from the blowing direction of the outlet 7. For this reason, the air-conditioned air can reach the corner of the room.

  Thereby, at the time of heating operation of an air conditioner, warm air can be conveyed also to the place where the step is cold. Further, it is possible to prevent the feet from getting too cold during the cooling operation.

  In the present embodiment, the front panel 4 has been described as not moving forward and backward with respect to the front surface of the indoor unit 1. However, a panel drive mechanism may be provided and separated from the front opening 3b. . In this case, the length of the arm portion 26a of the fixture 26 may be sufficiently long so as not to hinder the separation operation of the front panel 4. However, in terms of easily securing the strength of the fixture 26, it is preferable that the front panel 4 of the indoor unit 1 is not movable back and forth with respect to the front surface because the length of the arm portion 26a can be shortened.

  As described above, in the present embodiment, by attaching the auxiliary device 21 to the indoor unit 1, the amount of air blown from the indoor unit 1 can be increased, and the air conditioning capability can be improved. Moreover, it removes from the indoor unit 1 and installs it indoors, interlocks with the indoor unit 1 and rotates the fan 25 of the auxiliary device 21 so that the air current can be delivered to the corner of the room, thereby improving the indoor living environment. I can do it.
