  However, in the conventional configuration, an ideal airflow can be generated upward during cooling operation and downward during heating operation. However, as shown in FIG. Airflow diffuses at the moment of exit. For this reason, the airflow cannot be bent to the intended maximum angle when the left and right wind directions are changed, and there is a problem that there is a limit in guiding the airflow far away because the flow velocity decreases.

  The present invention solves the above-described conventional problems, and provides an air conditioner that can create an ideal upward and downward airflow while expanding the blowing angle of the wind in the left-right direction and guiding the wind to a further distance. The purpose is to do.

In order to solve the above-described conventional problems, an air conditioner of the present invention includes a heat exchanger, an air outlet that blows out air that has been heat-exchanged by the heat exchanger, and an air that is disposed and blown out at the air outlet.

During cooling and cooling operation Are those only the second vertical airflow direction changing blade extending inner blade.

  As a result, even after leaving the air outlet, the air flow can be controlled while forming a flow path with two up / down air direction changing blades to prevent the air flow from being diffused. It is possible to increase the blowing angle of the wind to the wind and to guide the wind farther away.

The air conditioner of the present invention includes a first vertical airflow direction change blade having a center of rotation at an upper end on the downstream side of the outlet and a second center of rotation having a rotation center at a lower end on the downstream side of the outlet . The first vertical airflow direction changing blade and the second vertical airflow direction changing blade are respectively retracted into and out of the rotation center by extending and retracting the inner blades included in the first vertical airflow direction changing blade and the second vertical airflow direction changing blade. Since only the first up / down airflow direction changing blade extends the inner blade during heating operation, and only the second up / down airflow direction changing blade extends the inner blade during cooling operation. During cooling operation, there is no feeling of air current, and during heating operation, a comfortable living environment with head cold foot heat can be created.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiment.

(Embodiment 1)
FIG. 1 is a cross-sectional view of an air conditioner according to a first embodiment of the present invention, FIG. 2 is a structural diagram of an up / down air direction change blade of the air conditioner, and FIG. 3 shows an operating state of the air conditioner. It is a figure.

  As shown in FIG. 1, the air conditioner 1 forms a suction port 5 from the front surface to the upper surface of the main body 2, and has a heat exchanger 3, a fan 4, and a blowout grill 7 inside the main body 2. The heat exchanger 3 is disposed on the upstream side of the fan 4, and the blowout grill 7 forms a blower passage 9 and a blower outlet 6 on the downstream side of the fan 4, and the right and left wind direction changing blades 8 that blow the wind left and right, Are provided with a first up / down air direction changing blade 40 and a second up / down air direction changing blade 41.

  The air conditioner 1 also includes a panel 11 that opens and closes the suction port 5 on the front side, and a panel drive device 12 that opens and closes the panel 11. When the air conditioner 1 shown in FIG. 1 is stopped, the panel 11 is closed and the suction port 5 on the front side is closed.

  As shown in FIG. 1, the two upper and lower airflow direction changing blades 40 and 41 each having a rotation center 26 at the upper and lower ends on the downstream side of the air outlet 6 are both arcuate in cross section, and the air conditioner 1 shown in FIG. At the time of stopping, both the concave portions are on the upstream side, and the upper and lower wind direction changing blades 40 are arranged so as to block the upper part of the opening of the blower outlet 6, and the upper and lower wind direction changing blades 41 are closed. The edges on the opposite side of the rotation center 26 of the two vertical airflow direction changing blades 40 and 41 are close to each other, and the air outlet 6 is closed as a whole. That is, the total length of the two upper and lower airflow direction changing blades 40 and 41 and the upper and lower length of the opening of the air outlet 6 are substantially the same. In the present embodiment, the up / down wind direction changing blades 40 and 41 have the same shape, but the sizes may be different.

  Further, drive motors 42 and 43 are connected to the rotation center 26, and the operation of the drive motors 42 and 43 causes the up and down air direction changing blades 40 and 41 to rotate upward and downward, respectively.

  The upper and lower wind direction changing blades 40 and 41 have a double blade structure, and the length of the blades can be extended and retracted by taking in and out the inner blades contained in the opposite side of the rotation center 26. As shown in FIG. 2, the up / down airflow direction changing blade 40 is configured so that the inner blade 44 can be accommodated therein, and racks 45 are provided at both ends on the back side of the inner blade 44. The upper and lower wind direction changing blades 40 are respectively meshed with gears 46 accommodated therein. The gears 46 are connected by a shaft 47.

  A gear 48 is provided at one end of the up / down airflow direction changing blade 40 and is connected to the shaft 47. Further, since the gear 48 is connected to the up / down air direction changing blade 40 and the final gear 48 is connected to the drive motor 49, the inner blade 44 operates by the rotation of the drive motor 49, and the up / down air direction changing blade. It is stored in 40 or protrudes.

  The up / down air direction changing blade 41 has the same configuration as the up / down air direction changing blade 40.

  Next, the operation will be described with reference to FIG.

  When the air direction change mode of the air conditioner 1 is set to the upward direction (mainly cooling operation) and the operation is started, the panel 11 moves from the suction port 5 to the position farthest forward, as shown in FIG. Thus, the up / down air direction changing blade 41 is rotated downward by the drive motor 43 to open the lower portion of the air outlet 6 and moves to a position where the up / down air direction changing blade 41 is in an upward air blowing state upward from substantially horizontal. Thereafter, the inner blade 44 is extended by the rotation of the drive motor 49.

  On the other hand, the up / down wind direction changing blade 40 is rotated upward by the operation of the drive motor 42 so that the concave shape of the blade is substantially downward to open the upper portion of the outlet 6, and the up / down air direction changing blade 40 is downward from substantially horizontal. Move to the position. In this state, the air is blown upward.

Accordingly, the air passage 9 formed by the blow grill 7 is extended in the air blowing direction and the air passage cross-sectional area is narrowed, so that the diffusion of the air flow at the moment of exiting the air outlet can be prevented. Since the air is blown upward or horizontally along the blade shapes of the change blade 41 and the inner blade 44, it is possible to prevent the cold air from being directly applied to the person in the room.
In addition, the airflow is reduced by the up / down air direction changing blades 40 and the up / down air direction changing blades 41, and the flow velocity can be increased to guide the wind to a distance in the depth direction of the room.

  Next, the operation leading to the downward blowing state will be described.

  When the wind direction change mode of the air conditioner 1 is set to the downward direction (mainly heating operation) and the operation is started, the panel 11 moves to the position farthest away from the suction port 5 and is shown in FIG. 3 (b). Thus, the up / down wind direction changing blade 40 is rotated upward by the drive motor 42 to open the upper portion of the air outlet 6, and the up / down air direction changing blade 40 is moved to a position where the up / down air direction changing blade 40 is in a downward blowing state upward from substantially vertical. Thereafter, the inner blade 44 is extended by the rotation of the drive motor 49.

  On the other hand, the up / down air direction changing blade 41 is rotated downward by the operation of the drive motor 43 so that the concave shape of the blade is obliquely upward to open the lower portion of the air outlet 6, and the up / down air direction changing blade 41 is below the air passage 9. Move to a position that is substantially parallel to the edge. In this state, air is blown in the downward direction.

  Accordingly, the air passage 9 formed by the blow grill 7 is extended in the air blowing direction and the air passage cross-sectional area is narrowed, so that the diffusion of the air flow at the moment of exiting the air outlet can be prevented. Since the change blade 40 and the inner blade 44 are guided directly to the floor of the living room along the blade shape, it is possible to prevent the person in the living room from being directly exposed to the warm air.

  Moreover, since the airflow can be reduced by the up / down air direction changing blades 40 and the up / down air direction changing blades 41, the immediate effect of heating is improved.

  Next, the operation leading to the blown state in the oblique direction will be described.

  When the air direction change mode of the air conditioner 1 is set to an oblique direction (cooling operation, heating operation, etc.) and the operation is started, the panel 11 moves to the position farthest away from the suction port 5 to the position shown in FIG. As shown in FIG. 4, the up and down wind direction changing blades 40 are rotated upward and the up and down air direction changing blades 41 are rotated downward by the operations of the drive motor 42 and the drive motor 43, and the upper and lower openings of the air outlet 6 are opened. The up-and-down air direction changing blades 40 and 41 move to positions where they are in a state of blowing air in an oblique direction, which are substantially parallel to the upper and lower edges of the air passage 9, respectively. In this state, air is blown in an oblique direction.

  Here, in the up-and-down wind direction changing blades 40 and 41, the inner blade 44 may be extended or not. Further, the up / down air direction changing blade 40 and the up / down air direction changing blade 41 may be swung at a predetermined angle by the rotation of the driving motor 42 and the driving motor 43.

  Accordingly, the air passage 9 formed by the blow grill 7 is extended in the blow direction, so that the air current can be prevented from diffusing at the moment of exiting the air outlet. Since the blade 44 is guided to the center of the living room along the blade shape (including the inner blade 44 when the blade 44 is extended), cold air or hot air can be directly applied to the person in the living room. This blowing state is mainly used at the start of cooling and heating operations.

  Further, since the air flow can be reduced by the up / down air direction changing blade 40 and the up / down air direction changing blade 41, the directivity of the air flow can be improved and the immediate effect of cooling and heating can be improved.

  In addition, although description of operation | movement is abbreviate | omitted, the transfer operation | movement between each ventilation state is also possible.

Moreover, since the diffusion of the airflow can be prevented by the up-and-down airflow direction changing blades 40 and 41, the airflow can be bent to a predetermined maximum angle, and the air blowing range in the left-right direction of the living room can be expanded.

  As described above, in the present embodiment, the upper and lower ends of the downstream side of the air outlet 6 are provided with two blades of the upper and lower airflow direction changing blades 40 and the upper and lower airflow direction changing blades 41, respectively. The change blade 40 and the up / down air direction change blade 41 rotate independently of each other, and the blade length can be extended and retracted by inserting / removing the inner blade 44 included in the blade into / from the opposite side of the rotation center 26. Therefore, it becomes possible to expand the blowing angle of the wind in the left-right direction and to guide the wind far away from the room. Moreover, since the operation | movement of the up-and-down air direction change blade | wings 40 and 41 is simple, the transfer from the stop state of the air conditioner 1 to each ventilation mode and the transition between each ventilation mode can be performed easily.

  As described above, since the air conditioner of the present invention can perform various wind direction control and can send wind to every corner of the living room, in addition to indoor air conditioning, a dehumidifier and an air purifier It can also be applied to.
