FIG. 1 is an indoor unit configuration diagram of an air conditioner according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view of the air conditioner when viewed from a direction A in FIG.

  As shown in FIG. 1, the indoor unit 1 is provided with an air outlet 8 below, and is connected to the left and right sides of the air outlet 8 by a connecting bar 11a and a connecting bar 11b, and can rotate in the left-right direction. A plurality of left and right blades 10a and 10b having a simple axis are provided. Further, a plurality of central left and right blades 10c having a shaft rotatable in the left-right direction and connected to the connecting bar 11c are also provided at the center of the air outlet 8.

  In FIG. 2, the air conditioner of the present invention is provided with a front panel 2 on the front surface of an indoor unit 1, and an indoor heat exchanger 3 and a blower fan 4 are provided inside the indoor unit 1. An air inlet 5 is provided at the upper part of the indoor unit 1, and an air outlet 8 is provided at the lower part. The air outlet 8 is formed by a stabilizer 6 and a rear guider 7. Further, the upper and lower blades 9 for controlling the air direction and the above-described plural left and right blades 10 are provided at the outlet of the air outlet 8.

  In FIG. 1, a connecting beam (left) 11a and a connecting beam (right) 11b are connected to the air blowing port 8 to a driving unit (left) 12a and a driving unit (right) 12b, respectively. The connecting bar (center) 11c is provided with a round gear (center) 13c. The round gear (center) 13c includes a flat gear (left) 13a provided on the connecting bar (left) 11a and a connecting bar. (Right) It is sandwiched between flat gears (right) 13b provided in 11b, and these gears constitute a linkage mechanism 23 for connecting bars.

  The holder 14 is a part of the connecting bar, and holds the round gear (center) 13c and prevents the flat gear (left) 13a and the flat gear (right) 13b from separating from the round gear (center) 13c. It is a guide.

  About the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 3 shows the operation of each of the plurality of blades when the air flow is controlled by the movement of the plurality of blades of the air conditioner and the flow of air blown out from the indoor unit is to be concentrated in the center.

  According to this configuration, first, when it is desired to concentrate the flow of the air blown out from the indoor unit in the center, the connecting bar (left) 11a is pushed inward (center direction) by the drive unit (left) 12a. The plurality of left and right blades 10a on the left side are rotated accordingly, and are directed in a direction to bring the blowing flow toward the center. Similarly, the drive bar (right) 12b pushes the connecting bar (right) 11b inward (center direction) on the right side. The plurality of right and left blades 10b on the right side also rotate along with it and are directed in a direction to bring the blowing flow toward the center.

  At this time, the spur gear (left) 13a connected to the connecting bar (left) 11a transmits a force to rotate the round gear (center) 13c provided on the connecting bar (center) 11c. The right gear (right) 13b connected to the (right) 11b also transmits force to rotate the round gear (center) 13c provided on the connecting bar (center) 11c. The movement is canceled and the round gear (center) 13c is not moved from the spot.

  That is, in this case, the plurality of left and right blades 10c connected to the central connecting bar 11c are not driven at all.

  In other words, the left and right blades 10a and the right and left blades 10b try to move the blowing flow toward the center, and the central left and right blades 10c try to flow the blowing flow toward the center as a result. Creates an air flow that concentrates in the center.

  Next, in order to create an air current that spreads throughout the room, it can be realized by driving the left and right drive units in the opposite directions. FIG. 4 shows the operation of each of the plurality of blades when it is desired to spread the airflow over the entire room by controlling the air direction of the air conditioner.

  As shown in FIG. 4, in this case, the left and right blades 10a of the left block rotate to a position where they are blown to the left, and the left and right blades 10b of the right block rotate to a position where they are blown to the right. The left and right blades 10c of the central block again flow out of the center without changing their positions. As a result, it is possible to create an air current that spreads throughout the room.

  As an example of other cases, when it is desired to realize an airflow that spreads from the front to the left, it is necessary to blow the left-hand blowing flow to the left and the right-hand blowing flow to the front.

  FIG. 5 shows the operation of a plurality of blades that realizes an airflow spreading from the front to the left. Here, first, the connecting bar (left) 11a is pulled out by the drive unit (left) 12a. A plurality of left and right blades 10a on the left side are rotated accordingly, and are directed in a direction to draw the blown flow toward the left side. At this time, the drive unit (right) 12b is kept stopped, and the connecting bar (right) 11b is not driven. Naturally, since the right and left blades 10b on the right side are not driven, the blowing flow is a flow in the front direction.

  The spur gear (left) 13a provided on the connecting bar (left) 11a rotates the round gear (center) 13c provided on the connecting bar (center) 11c, but is provided on the connecting bar (right) 11b. Since the flat gear (right) 13b is in a stopped state, the round gear (center) 13c moves as a result of a distance that is half the amount of movement of the flat gear (left) 13a. In other words, the plurality of left and right blades (center) 10c connected to the connecting bar (center) 11c rotate in a direction to draw a blown flow toward the left side by a half angle of the left and right blades 10a.

  As described above, the left and right blades 10a move the blowing flow to the left, the right left and right blades 10b cause the blowing flow to flow in the front, and the left and right blades 10c in the center create a slightly left blowing flow. As a result, an airflow spreading from the front to the left will be created.

  As described above, the air conditioner of the present invention divides the left and right blades into three blocks and controls the blowout flow to create an air current spreading throughout the room, an air current concentrated in one place, etc. An air-conditioned space can be provided. Further, since only two drive units are required to drive the three blocks of the left and right blades, it is possible to suppress the cost increase, and to provide an air conditioner that is more inexpensive and has improved comfort.

  In the above description of the embodiment, the description has been given of the case where the linkage between the left and right blade connecting bars located on the left and right sides and the left and right blade connecting bars located at the center is linked by the gear mechanism. The linkage mechanism 23 may be configured in any way as long as the linkage bars of the left and right blades and the linkage bars of the left and right blades located in the center can be linked as described in the embodiment.

  In addition, in this example, the drive unit of the left and right blade connecting bars located on the left and right sides uses a link mechanism to transmit the rotation of the motor to the connecting bars. You may drive the connecting bar using.

  As described above, the air conditioner according to the present invention can be used in a blower device that needs to blow an air blowing flow with an inexpensive configuration.
