(5) Features of the air conditioner In the air conditioner 100 of the present embodiment, the control unit 180 adjusts the second wind direction adjusting member 160 and the third wind direction adjusting member 170 when the wind direction is adjusted to the front lower direction. Use. In other words, the control unit 180 is located between the first wind direction adjusting member 150 and the second wind direction adjusting member 160, so that the third wind direction adjusting member 170 that can act as a resistance is replaced with the second wind direction adjusting member. Together with 160, it is actively used to adjust the wind direction. At the same time, when the third wind direction adjusting member 170 is used for adjusting the wind direction, the first wind direction adjusting member 150 that can act as a resistance is moved to the retracted position. As described above, it is possible to suppress a reduction in the air volume of the conditioned air.

  In the air conditioner 100 of the present embodiment, the control unit 180 adjusts the wind direction to the rear lower direction, in addition to the second wind direction adjusting member 160 and the third wind direction adjusting member 170, the first wind direction adjusting member. 150 is used. And the 3rd wind direction adjustment member 170 forms the guide surface which guides conditioned air with the 1st wind direction adjustment member 150. FIG. The first air direction adjusting member 150 and the third air direction adjusting member 170 are integrated to form a guide surface, so that conditioned air enters between the first air direction adjusting member 150 and the third air direction adjusting member 170. It becomes difficult. Since the loss of the conditioned air volume caused by entering between the first wind direction adjusting member 150 and the third wind direction adjusting member 170 can be reduced, the reduction of the conditioned air volume blown from the outlet 111 is suppressed. it can.

  Since the first guide surface 152 and the third guide surface 172 form an arcuate shape protruding forward as a whole, the conditioned air can follow the arcuate shape. Thereby, the wind direction of conditioned air can be adjusted to a back lower direction without resistance.

  Further, in addition to the second wind direction adjusting member 160 and the third wind direction adjusting member 170, by using the first wind direction adjusting member 150, only the second wind direction adjusting member 160 and the third wind direction adjusting member 170 are used. Can achieve different wind directions. Since various wind directions can be realized, it can be expected to provide wind directions that meet the user's requirements.

  In the air conditioner 100 of the present embodiment, the control unit 180 adjusts the air direction in the rear lower direction, that is, the direction toward the side wall during the heating operation. Thereby, it can be expected that warm air that is conditioned air reaches the floor surface via the wall. When warm air reaches the floor, it can be expected that the room in which the air conditioner is installed is uniformly warmed.

  In the air conditioner 100 of the present embodiment, the first direction is the front lower side, that is, the direction away from the side wall, and the second direction is the rear lower side, that is, the direction toward the side wall. In other words, the conditioned air adjusted in the second direction is closer to the side wall than the conditioned air adjusted in the first direction.

  The control unit 180 adjusts the wind direction in a direction away from the side wall or in a direction toward the side wall, and selects one of the first wind direction adjusting member 150, the second wind direction adjusting member 160, and the third wind direction adjusting member 170. Use differently. That is, the first wind direction adjusting member 150, the second wind direction adjusting member 160, and the third wind direction adjusting member 170 can be properly used according to the wind direction.

  When the wind direction is adjusted in a direction away from the side wall, the blowout flow path 114 extends linearly from the guide flow path 113 as shown in FIG. Or as FIG. 4 shows, the blowing flow path 114 from the guide flow path 113 is connected to the comparatively gentle curve shape. Therefore, even the third wind direction adjusting member 170 smaller than the first wind direction adjusting member 150 can sufficiently adjust the wind direction.

  On the other hand, when the wind direction is adjusted in the direction toward the side wall, as shown in FIG. 2, the blowout flow path 114 extends from the guide flow path 113 to a steep curve. Therefore, the wind direction is adjusted by the first wind direction adjusting member 150 in addition to the third wind direction adjusting member 170. Since the conditioned air is guided along the third wind direction adjusting member 170 that is larger than the first wind direction adjusting member 150 and then guided to the second wind direction adjusting member 160, the wind direction can be adjusted efficiently in the lower rear direction. it can.

  In the air conditioner 100 of the present embodiment, the third wind direction adjusting member 170 is disposed in the guide channel 113 on the upstream side of the conditioned air flow with respect to the first wind direction adjusting member 150. When the wind direction of the conditioned air is adjusted on the upstream side, the conditioned air is easily along the second wind direction adjusting member 160 when the wind direction is adjusted to the lower rear side.

  In the air conditioner 100 of the present embodiment, the width in the short direction of the third air direction adjusting member 170 is narrower than the width in the short direction of the first air direction adjusting member 150. Therefore, the third wind direction adjusting member 170 is easily accommodated in a limited space in the main body casing 110.

  In the air conditioner 100 of the present embodiment, the first air direction adjusting member 150 has a tapered portion 153. Therefore, when the wind direction is adjusted in a direction including the vertically upward component, the taper portion 153 of the first wind direction adjusting member 150 can be more easily guided in the direction. On the other hand, the control unit 180 moves the first wind direction adjusting member 150 to the retracted position away from the guide channel 113 and the outlet channel 114 when adjusting the wind direction in the lower front direction, so the first wind direction adjusting member The influence by 150 can be reduced. That is, the air volume of the conditioned air flowing in the direction including the vertically upward component can be reduced.

  In the air conditioner 100 of the present embodiment, the control unit 180 controls the inclination angles of the first wind direction adjusting member 150, the second wind direction adjusting member 160, and the third wind direction adjusting member 170 with respect to the horizontal plane. By controlling the postures of the first wind direction adjusting member 150, the second wind direction adjusting member 160, and the third wind direction adjusting member 170, the wind direction of the conditioned air can be adjusted.

Good. When the third wind direction adjusting member 170 overlaps the first wind direction adjusting member 150, the first guide surface 152 and the third guide surface 172 may be formed in a stepped shape. Since the third wind direction adjusting member 170 is positioned so as to ride on the first wind direction adjusting member 150, the third wind direction adjusting member 170 covers the step portion 154, so that the first wind direction adjusting member 150 and the third wind direction adjusting member 170 It is possible to further reduce the air volume entering between.

(2) Modification B
In the above description, the third wind direction adjusting member 170 is pivotally attached to the lower portion of the main body casing 110, but may be attached so as to freely advance and retract. That is, the third wind direction adjusting member 170 may perform a linear motion instead of a circular motion. Further, the third wind direction adjusting member 170 may be fixed to the lower portion of the main body casing 110 while maintaining a specific posture. In this case, since the posture of the third wind direction adjusting member 170 is not changed, the control unit 180 only needs to control the postures of the first wind direction adjusting member 150 and the second wind direction adjusting member 160.

(3) Modification C
The second guide surface 162 may be provided with a tapered portion. The taper portion is located at the tip of the second guide surface 162. When the 2nd wind direction adjustment member 160 takes the attitude | position which inclined back downward, a taper part guides the conditioned air which blows off from the blower outlet 111 to back lower side. Therefore, it becomes easier to guide the wind direction to the lower rear side.

  The third guide surface 172 may be provided with a reverse tapered portion. The reverse taper portion is located at the tip of the third guide surface 172. When the third wind direction adjusting member 170 takes a posture that is inclined rearward and downward or takes a substantially vertical posture, the reverse taper portion guides the conditioned air blown out from the air outlet 111 to the rear lower side. This makes it easier to guide the wind direction to the lower rear side.

(4) Modification D
In the above description, when the wind direction is set to the front lower side direction, the control unit 180 accommodates the first wind direction adjusting member 150 in the accommodation unit 112, but it is separated from the guide channel 113 and the outlet channel 114. It is not necessary to accommodate in the accommodating part 112 if it is a position. Moreover, the air conditioner 100 may adjust the wind direction in three or more different front lower directions.

(5) Modification E
In the above description, the first direction is the front lower side, and the second direction is the rear lower side. However, both the first direction and the second direction may be the front lower side, or the first direction. Both of the second direction and the lower side may be provided. Also in these cases, the conditioned air adjusted in the second direction is closer to the side wall than the conditioned air adjusted in the first direction. That is, the second direction is closer to the side wall than the first direction. Therefore, for example, when both the first direction and the second direction are the rear lower side, the first wind direction is added to the third wind direction adjusting member 170 when the wind direction is adjusted to the second direction approaching the side wall. By using the adjustment member 150, the wind direction can be adjusted efficiently in the rear lower direction.

(6) Modification F
In the above description, the case where the operation mode is set to heating is described as an example, but the present invention can be applied even when the operation mode is set to humidification or humidification heating.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be made to the above embodiments. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
