It is smaller and is arranged inside the outlet 6 on the back side of the first up / down air direction changing blade 13 so as to be hidden by the first up / down air direction changing blade 13 (hereinafter, the first up / down air direction changing blade is Wind direction change blade large, the second up and down wind direction change blade is referred to as the up and down wind direction change blade small).

  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. 2, the up-and-down air direction changing blade large 13 is rotatably held by a pair of first arm portions 14 a and 14 b provided at the left and right opening ends of the air outlet 6. 14a is provided with a drive motor 18 for rotating the large vertical airflow direction changing blade 13 around a rotation center 26 disposed on the action point side of the first arm portions 14a, 14b, that is, on the distal end side. As shown in FIG. 1, the first arm portion 14b is connected to a drive motor 17 via a gear 16, and a shaft 15 is provided so that the first arm portion 14a is interlocked with 14b. Thus, the first arm portions 14a and 14b are operated with the shaft 15 disposed in the vicinity of the lower end of the air outlet 6 as a fulcrum. The first arm portions 14a and 14b are symmetrical with each other, and operate in parallel so that the up-and-down wind direction changing blade size 13 is not twisted.

  The small up-and-down air direction changing blade 21 is arranged on the back side of the up-and-down air direction changing blade large 13, and as shown in FIG. 2, a pair of second arm portions 22a and 22b provided inside the first arm portions 14a and 14b. Is held rotatably. The rotation of the drive motor 25 is transmitted to the vertical airflow direction change blade 21 through a drive transmission means (not shown) such as a wire or a belt provided in the second arm portion 22a, and the second arm portion 22a, The rotating operation is performed around the rotation center 26 disposed on the side of the action point 22b, that is, the front end side. As shown in FIG. 1, the second arm portion 22b is connected to a drive motor 24 through a gear 27, and a shaft 23 is provided so that the second arm portion 22a is interlocked with 22b. Thus, the second arm portions 22a and 22b are operated with the shaft 23 disposed in the vicinity of the lower end of the air outlet 6 as a fulcrum. The second arm portions 22a and 22b are also bilaterally symmetric with each other and operate in parallel so as not to twist the vertical wind direction changing blade small 21.

  The operations of the drive motor 24 and the drive motor 25 are controlled by an operation control unit (not shown). The operation control unit also controls the drive of the drive motor 17, the drive motor 18, and the panel drive device 12.

  The first arm portions 14 a and 14 b, the up and down air direction changing blade large 13, the second arm portions 22 a and 22 b, and the up and down air direction changing blade small 21 are housed in a nested manner when the air conditioner 1 is stopped.

  Next, the operation will be described with reference to FIGS. FIG. 1 is a diagram showing a stopped state of the air conditioner 1, and the panel 11, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 are all closed. 3 to FIG. 5 represents the operation process of the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21.

  When the operation is started by setting the wind direction change mode of the air conditioner 1 to the upward direction (mainly cooling operation) by a remote controller (not shown), the panel 11 is moved by the operation of the panel drive device 12 as shown in FIG. It moves from the suction port 5 to the position farthest forward. At the same time, the drive motor 17 causes the first arm portions 14 a and 14 b to rotate downward with a shaft 15 disposed near the lower end of the air outlet 6 as a fulcrum, and the up and down airflow direction changing blade large 13 is moved forward from the air outlet 6. While moving away to a predetermined position so that the air outlet 6 is opened, the up / down airflow direction changing blade 13 is rotated around the rotation center 26 on the tip side of the first arm portions 14a, 14b by the operation of the drive motor 18. The lower end portion of the air outlet 6 substantially contacts the lower end of the most downstream end portion of the outlet 6.

  On the other hand, by the operation of the drive motor 25, the up-and-down air direction changing blade small 21 is rotated upward about the rotation center 26 on the tip side of the second arm portions 22a and 22b so that the concave shape of the blade is substantially downward. In addition, the second arm portions 22a and 22b operate with the shaft 23 arranged near the lower end of the outlet 6 as a fulcrum by the rotation of the drive motor 24, and the upper and lower airflow direction changing blades 21 are arranged downstream of the outlet 6. It moves to an upper end part, The upper part substantially contact | abuts to the upper part of the most downstream end part of the blower outlet 6. FIG. In this state, the air is blown upward.

  The upper and lower airflow direction changing blade large 13 is moved out of the locus of the upper and lower airflow direction changing blades 21 before the upper and lower airflow direction changing blade small 21 is moved so that the upper and lower airflow direction changing blades 21 and 21 do not collide with each other.

  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 in the upward direction or the horizontal direction along the blade shape of the changed blade size 13, it is possible to prevent the cold air from being directly applied to the person in the room.

In addition, as shown in FIG. 6 (b), it is possible to guide the wind to a distance in the depth direction of the room by constricting the air flow with the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 and increasing the flow velocity. It becomes.

  Note that the operation from the upward blowing state to the stopped state is the reverse of the operation from the stopped state to the upward blowing state described above, and thus the description thereof is omitted.

  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 a downward direction (mainly heating operation) by a remote controller (not shown) and the operation is started, the panel 11 is moved by the operation of the panel drive device 12 as shown in FIG. It moves from the suction port 5 to the position farthest forward. At the same time, the first arm portions 14 a and 14 b are rotated downward about the shaft 15 by the drive motor 17, so that the large vertical airflow direction changing blade 13 is spaced forward from the air outlet 6 so that the air outlet 6 opens. While moving to a predetermined position indicated by a two-dot chain line in FIG. 4, the up / down wind direction changing blade 13 is rotated upward about the rotation center 26 to the position of the two-dot chain line in FIG. The upper end of the upper end substantially contacts the uppermost end of the most downstream side of the outlet 6.

  On the other hand, the second arm portions 22 a and 22 b are rotated downward about the shaft 23 by the drive motor 24, and the small vertical wind direction changing blade 21 is moved to the lowermost portion of the outlet 6. Thereafter, the upper and lower airflow direction changing blades 13 rotate to the position of the downward blowing state, and the first arm portions 14a and 14b operate to a position where the upper end portion is substantially in contact with the upper portion of the downstream end portion of the air outlet 6. To do. Further, the small up-and-down air direction changing vane 21 is rotated by the operation of the drive motor 25 to a position where the lower end portion thereof is substantially in contact with the lower end of the most downstream end portion of the outlet 6. In this state, air is blown in the downward direction.

  The upper and lower airflow direction changing blade large 13 is moved out of the locus of the upper and lower airflow direction changing blades 21 before the upper and lower airflow direction changing blade small 21 is moved so that the upper and lower airflow direction changing blades 21 and 21 do not collide with each other. Specifically, when the up-and-down wind direction changing blade large 13 moves to a predetermined position indicated by a two-dot chain line in FIG. 4 so as to be spaced forward from the outlet 6 and the outlet 6 is opened, the second arm portion 22a, 22b begins to rotate downward with the shaft 23 as a fulcrum, and the vertical wind direction changing blade is synchronized with the rotation center 26 of the small vertical wind direction changing blade 21 passing through the vicinity of the rotational center 26 of the large vertical direction changing blade 13 Both the up / down air direction change blades 13 and 21 are moved so that the large 13 and the up / down air direction change blade small 21 do not collide.

  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 it is led directly to the floor surface of the living room along the blade shape of the changed blade size 13, it is possible to prevent the hot air from being directly applied to the person in the living room.

  Moreover, as shown to Fig.6 (a), since an airflow can be shrunk by the up-and-down air direction change blade large 13 and the up-and-down air direction change blade small 21, the immediate effect of heating improves.

  Note that the operation from the downward blowing state to the stopped state is the reverse of the operation from the stopped state to the downward blowing state described above, and a description thereof will be omitted.

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

When the wind direction change mode of the air conditioner 1 is set to an oblique direction (cooling operation, heating operation, etc.) by a remote controller (not shown) and the operation is started, as shown in FIG. 11 moves from the suction port 5 to the position farthest forward. At the same time, the first arm portions 14a and 14b are rotated downward about the shaft 15 by the rotation of the drive motor 17, and the large vertical airflow direction changing blade 13 is separated forward from the outlet 6 so that the outlet 6 is opened. While moving to a predetermined position indicated by a two-dot chain line in FIG. 5 so as to open, the up / down air direction changing blade large 13 is not shown in FIG. Rotate upward to the position of the two-dot chain line.

  Next, the second arm portions 22 a and 22 b are rotated downward with the shaft 23 as a fulcrum by the rotation of the drive motor 24, and the small vertical wind direction changing blade 21 is moved to the lower portion of the air outlet 6. Thereafter, the up / down wind direction changing blade 13 is rotated around the rotation center 26 to a position where the driving motor 18 is operated to be blown in an oblique direction, and at a predetermined position by the operation of the first arm portions 14a, 14b. And is located approximately in the center of the air passage. Further, the small up-and-down air direction changing blade 21 is rotated around the rotation center 26 until the lower end thereof is located near the lower end of the most downstream end of the air outlet 6 by the operation of the drive motor 25, and is inclined in the oblique direction. Move to the position where the air blows. Here, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 may be swung at a predetermined angle by the rotation of the driving motor 18 and the driving motor 25.

  The upper and lower airflow direction changing blade large 13 is moved out of the locus of the upper and lower airflow direction changing blades 21 before the upper and lower airflow direction changing blade small 21 is moved so that the upper and lower airflow direction changing blades 21 and 21 do not collide with each other.

  Since the airflow is guided to the center of the living room along the blade shape of the up-and-down airflow direction changing large blade 13, 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.

  Moreover, as shown in FIG.6 (c), since an airflow can be shrunk by the up-and-down air direction change blade large 13 and the up-and-down air direction change blade small 21, the directivity improvement of airflow and the immediate effect of cooling and heating are possible. Improvement can be achieved.

  Note that the operation from the oblique ventilation state to the stop state is the reverse of the above-described operation from the stop state to the oblique ventilation state, and thus the description thereof is omitted.

  Moreover, the transition operation | movement between each ventilation state is also possible.

  In the transition from the upward air blowing state to the downward air blowing state, first, the vertical air direction changing blade small 21 shown in FIG. 3 is rotated to the position of the stop state shown in FIG. That is, the vertical airflow direction changing small blade 21 is rotated downward about the rotation center 26 in the direction of closing the air outlet 6.

  Next, the first arm portions 14a and 14b are moved upward with the shaft 15 as a fulcrum to the position of the two-dot chain line shown in FIG. 6 After rotating to the position indicated by the two-dot chain line in the drawing so that the concave portion side becomes the center side of the outlet 6 in the direction of closing the upper portion and opening the lower portion, the second arm portions 22a and 22b are pivoted. It operates using 23 as a fulcrum, and moves the small up-and-down airflow direction vane small 21 to the lowest part of the air outlet 6. Thereafter, the up / down air direction changing blade large 13 is rotated further upward about the rotation center 26 to the position of the downward blowing state, and the upper end of the large up / down air direction changing blade 13 is substantially in contact with the upper portion of the downstream end of the outlet 6. The first arm portions 14a and 14b move upward with the shaft 15 as a fulcrum. Further, the vertical wind direction changing blade small 21 is rotated upward about the rotation center 26 to a position where the lower end portion thereof is substantially in contact with the lower end of the most downstream end portion of the outlet 6 by the operation of the drive motor 25.

  The transition from the downward blowing state to the upward blowing state is an operation reverse to the above-described transition operation from the upward blowing state to the downward blowing state.

  In the transition from the upward air blowing state to the oblique air blowing state, first, the vertical air direction changing blade small 21 shown in FIG. 3 is rotated to the position of the stopped state shown in FIG. That is, the vertical airflow direction changing small blade 21 is rotated downward about the rotation center 26 in the direction of closing the air outlet 6.

  Next, the first arm portions 14a and 14b are moved upward with the shaft 15 as a fulcrum to the position of the two-dot chain line shown in FIG. The second arm portions 22a and 22b are operated with the shaft 23 as a fulcrum, and the up / down air direction change vane small 21 is moved to the outlet 6 by turning upward in the direction to the position indicated by the two-dot chain line in FIG. Move to the bottom. Thereafter, the upper and lower wind direction changing blades 13 are rotated upward around the rotation center 26 to a position where the blades 13 are in a slanting direction, the concave side is directed downward, and the shafts 15 of the first arm portions 14a and 14b. Is moved to a predetermined position by an upward operation with fulcrum as a fulcrum, and is positioned at the approximate center of the air passage. Further, the small up-and-down air direction changing blade 21 is rotated around the rotation center 26 until the lower end thereof is located near the lower end of the most downstream end of the air outlet 6 by the operation of the drive motor 25, and is inclined in the oblique direction. It rotates to the position where it becomes a blowing state.

  Since the transition from the oblique air blowing state to the upward air blowing state is the reverse operation of the above-described transition operation from the upward air blowing state to the oblique air blowing state, the description thereof is omitted.

  In the transition from the downward blowing state to the oblique blowing state, the upper and lower air direction changing blades 13 shown in FIG. 4 are rotated to the blowing position in the oblique direction shown in FIG. 5 and the second arm portion 22a shown in FIG. , 22b is operated and moved to the position shown in FIG. 5, and then the up / down air direction changing blade small 21 is rotated to the blowing position in the oblique direction. That is, the upper and lower airflow direction changing blades 13 are rotated upward about the rotation center 26 and are rotated in the direction of opening the upper part of the closed outlet 6 so as to be positioned substantially at the center of the air passage, and the second arm portion. The small vertical airflow direction change blades 21 are rotated upward about the rotation center 26 while operating the shafts 23a and 22b upward with the shaft 23 as a fulcrum so as to be positioned substantially parallel to the large vertical airflow direction change blades 13.

  Since the transition from the oblique ventilation state to the downward ventilation state is an operation reverse to the above-described transition operation from the downward ventilation state to the oblique ventilation state, the description thereof is omitted.

  Furthermore, in the configuration of the first embodiment, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 rotate independently of each other and can be interchanged in the up / down position. Is omitted, but as shown in FIGS. 6 (e) and (f), the air to be blown can be divided into two layers, or the air to be blown can be divided into two directions as shown in FIG. 6 (g). Therefore, various wind direction control can be realized.

  Here, the air blowing state in the left-right direction will be described with reference to FIGS. 13 and 14.

  FIG. 13A is a cross-sectional view showing a downward blowing state of the air conditioner 1 of the present invention, and FIG. 13B shows a rightward blowing state of the air conditioner 1 of the present invention. It is a top view. 14A is a cross-sectional view showing a downward blowing state of the air conditioner 1 of the conventional example, and FIG. 14B shows a blowing state of the right direction toward the air conditioner 1 of the conventional example. It is the shown top view. In addition, the arrow in a figure represents the flow of the air to blow off.

  The change of the air direction of the air blown out in the left and right direction is performed by a plurality of left and right air direction changing blades 8 provided on the upstream side of the air outlet 6. However, in the conventional air conditioner, as shown in FIGS. 14 (a) and 14 (b), the airflow diffuses at the moment when the airflow exits from the outlet 6 because the up-and-down airflow direction changing blade 13 is composed of one sheet. Resulting in. For this reason, even if the wind direction is changed by the left and right wind direction changing blades 8, it cannot be bent to the intended predetermined maximum angle.

  Therefore, in the configuration of the present invention, as shown in FIGS. 13 (a) and 13 (b), since the diffusion of the airflow can be prevented with the small up and down airflow direction changing blades 21, the airflow is bent to a predetermined maximum angle. It becomes possible, and the ventilation range to the left-right direction of a living room can be expanded.

  Next, the above-described configuration will be supplementarily described with reference to FIG. FIG. 7 is an enlarged cross-sectional view showing the operation of the small up and down air direction change blades of the air conditioner, where (a) shows the center of rotation at the blade end, and (b) shows the center of rotation at the center of the blade. The case where it arrange | positions is shown.

  For example, as shown in FIG. 7 (b), when the up / down air direction changing vane small 21 is provided in the central portion of the outlet 6 and the rotation center 26 is provided in the central portion of the up / down air direction changing vane small 21, Since the trajectory 30 of the rotation center 26 of the up / down air direction change blade small 21 is irregular as shown by the alternate long and short dash line, the second up / down air direction change blade small 21 is held and driven at the time of transition to each blowing mode. The arm portions 22a and 22b need to move in two directions, up and down and left and right. For this reason, the second arm portions 22a and 22b must be configured with two axes, and the structure becomes complicated and the number of parts increases.

The large wind direction changing blade 13 is provided on the front side, and the small up and down air direction changing blade 21 is provided on the back side of the up and down air direction changing blade large 13.

  The up / down air direction change blade large 13 is arranged so as to be substantially closed with the same size as the air outlet 6, and the up / down air direction change vane small 21 is smaller than the up / down air direction change blade large 13 and the up / down air direction change. On the back side of the large blade 13, it is arranged in the outlet 6 so as to be hidden by the large vertical airflow direction changing blade 13.

  Similar to the first embodiment, the up-and-down air direction changing blade large 13 is rotatably held by a pair of first arm portions 14a and 14b provided at the left and right opening ends of the air outlet 6. The arm portion 14a is provided with a drive motor 18 for rotating the large up-and-down wind direction changing blade 13 around a rotation center 26 arranged on the action point side, that is, the tip side of the first arm portions 14a and 14b. Yes. The first arm portion 14b is connected to the drive motor 17 via the gear 16, and a shaft 15 is provided so that the first arm portion 14a is interlocked with 14b. The drive motor 17 causes the first arm portion 14a to be linked. And 14b are operated with a shaft 15 disposed in the vicinity of the lower end of the outlet 6 as a fulcrum. The first arm portions 14a and 14b are symmetrical with each other, and operate in parallel so that the up-and-down wind direction changing blade size 13 is not twisted.

  The up / down air direction change vane small 21 is arranged on the back side of the up / down air direction change vane large 13, and the column 31 provided with the rotation center 26 provided on the back side of the up / down air direction change vane small 21 on the concave side. Is held rotatably. Further, the support 31 is provided with a drive motor 25, and the drive motor 25 is connected to the rotation center 26, and the operation of the drive motor 25 causes the up / down wind direction changing blade small 21 to be in an optimal position in each air blowing state described later. Rotate to be placed. In addition, the support | pillar 31 is provided with two or more inside the 1st arm parts 14a and 14b described in 1st Embodiment, and operate | moves in parallel so that the up-and-down wind direction change blade | wing small 21 may not twist.

  Next, the operation will be described with reference to FIG. 9. Since the operation of the panel 11 is the same as that of the first embodiment, the description thereof will be omitted. In addition, a two-dot chain line shown in the figure shows an operation process of the up / down wind direction changing blade small 21.

  As in the first embodiment, 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 reaches the position farthest away from the suction port 5 forward. As shown in FIG. 9 (a), the first arm portions 14a and 14b are rotated downward by the drive motor 17 with the shaft 15 disposed in the vicinity of the lower end of the outlet 6 as a fulcrum, and the vertical wind direction is changed. The large blade 13 moves to a predetermined position so that the large outlet 13 is spaced forward from the outlet 6 and the outlet 6 is opened, and the up and down airflow direction changing large blade 13 is moved by the operation of the drive motor 18 to the first arm portions 14a, 14b. It rotates around the rotation center 26 on the front end side, and its lower end is substantially in contact with the lower part of the most downstream end of the outlet 6.

  Along with this, the column 31 continuously provided on the concave side of the up / down air direction changing blade large 13 and the small up / down air direction changing blade 21 held by the column 31 also move in the direction away from the outlet 6 in the forward direction.

  Thereafter, by the operation of the drive motor 25, the up / down air direction changing blade small 21 is rotated upward about the rotation center 26 of the support column 31 so that the concave shape of the blade is substantially downward, and the upper portion of the small outlet 21 is the air outlet 6. It is made to substantially contact | abut to the upper part of a downstream end part. In this state, the air is blown upward.

The upper and lower airflow direction changing blade large 13 is moved out of the locus of the upper and lower airflow direction changing blades 21 before the upper and lower airflow direction changing blade small 21 is moved so that the upper and lower airflow direction changing blades 21 and 21 do not collide with each other.

  Here, the lower end portion of the up / down airflow direction changing large blade 13 is substantially below the lowermost end portion of the blower outlet 6, and the upper portion of the up / down airflow direction changing blade small portion 21 is substantially above the uppermost end portion of the blowout outlet 6. The shapes of the up-and-down air direction changing blade large 13, the up-and-down air direction changing blade small 21, the support column 31 and the like are determined so as to contact each other. That is, the sum of the length from the blade portion of the up / down air direction changing blade large 13 to the rotation center 26 of the support column 31 and the length from the rotation center 26 of the support column 31 to the blade portion of the up / down air direction changing blade small 21 is the outlet 6. The shape is determined to be substantially the same as the length between the upper and lower ends of the opening.

  As described above, the air passage 9 formed by the blow-out grill 7 is extended in the air blowing direction and the cross-sectional area of the air passage 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 shape of the large vertical airflow direction change blade 13, it is possible to prevent the cold air from being directly applied to the person in the room.

  Further, the air flow is reduced by the up / down air direction change vane large 13 and the up / down air direction change vane small 21 and the flow velocity can be increased to guide the wind far to the depth direction of the living room.

  Note that the operation from the upward blowing state to the stopped state is the reverse of the operation from the stopped state to the upward blowing state described above, and thus the description thereof is omitted.

  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. 9B. As described above, the first arm portions 14a and 14b are rotated downward about the shaft 15 by the drive motor 17, so that the up / down airflow direction changing blade 13 is spaced forward from the outlet 6 and the outlet 6 is opened. After moving to a predetermined position, the upper and lower airflow direction changing blades 13 are moved to a position where the upper end portion thereof does not interfere with the uppermost downstream side upper edge portion of the outlet 6, and then the upper and lower airflow direction changing blades 13 are moved by the operation of the drive motor 18. Is rotated upward about the rotation center 26 to the position of the air blowing state, and the first arm portions 14a and 14b operate to a position where the upper end portion thereof is substantially in contact with the upper portion of the downstream end portion of the air outlet 6. To do.

  Along with this, the support 31 connected to the up / down air direction change blade large 13 and the up / down air direction change blade small 21 held by the support 31 also move forwardly away from the outlet 6 in the direction of the two-dot chain line in FIG. Move to position.

  Thereafter, the up-and-down wind direction changing blade 21 is rotated downward about the rotation center 26 by the operation of the drive motor 25, and the lower end portion thereof substantially contacts the lower portion of the most downstream end portion of the air outlet 6. 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 it is led directly to the floor surface of the living room along the blade shape of the changed blade size 13, it is possible to prevent the hot air from being directly applied to the person in the living room.

  Moreover, since the air flow can be reduced by the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21, the immediate effect of heating is improved.

Note that the operation from the downward blowing state to the stopped state is the reverse of the operation from the stopped state to the downward blowing state described above, and a description thereof will be omitted.

  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 from the suction port 5 to the position farthest forward, and FIG. 9 (c). 1, the first arm portions 14 a and 14 b are rotated downward about the shaft 15 by the drive motor 17, and the large vertical airflow direction changing blade 13 is spaced forward from the air outlet 6 to open the air outlet 6. The upper and lower wind direction changing blades 13 are moved to a predetermined position so that the upper end moves to a position where the uppermost downstream side of the blower outlet 6 does not interfere with the upper and lower wind direction changing blades. The upper and lower airflow direction changing blades 13 are substantially parallel to the airflow direction of the airflow from the airflow passage 9 and the air outlet 6 and are blown to the position where the main airflow 13 is inclined to the position where the airflow is in the oblique direction. Inside the exit 6 opening The first arm portion 14a of the upper and lower surfaces thereof in parts to a position where the blower passes, 14b is operated.

  Along with this, the support 31 connected to the up / down air direction change blade large 13 and the up / down air direction change blade small 21 held by the support 31 also move forwardly away from the outlet 6 in the direction of the two-dot chain line in FIG. Move to position.

  Thereafter, by the operation of the drive motor 25, the up-and-down air direction changing blade small 21 rotates downward about the rotation center 26 and moves to a position that is substantially parallel to the direction of the air flow from the air passage 9 and the air outlet 6. To do. In this state, air is blown in an oblique direction. Here, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 may be swung at a predetermined angle by the rotation of the driving motor 18 and the driving motor 25.

  Therefore, 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. Therefore, cold air or hot air can be directly applied to the person in the room. This blowing state is mainly used at the start of cooling and heating operations.

  In addition, since the air flow can be reduced by the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21, it is possible to improve the directivity of the air flow and the immediate effect of cooling and heating.

  Note that the operation from the oblique ventilation state to the stop state is the reverse of the above-described operation from the stop state to the oblique ventilation state, and thus the description thereof is omitted.

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

  Furthermore, in the configuration of the present embodiment, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 rotate independently of each other, and therefore, as described in the first embodiment, the air blown out is blown out. Since it is possible to make a two-layer airflow or to divert in two directions, various wind direction controls can be realized.

  In addition, as described in the first embodiment, since the diffusion of the airflow can be prevented with the small up and down airflow direction changing blades 21, it is possible to bend the airflow to a predetermined maximum angle, The blowing range can be expanded.

As described above, in the present embodiment, the air outlet 6 is provided with two blades of the large up-and-down air direction changing blade 13 and the up and down air direction changing blade small 21 that rotate independently of each other. A pair of variable first arms 14a for holding the up-and-down wind direction changing blade large 13 at the outlet 6 in a rotatable manner;
14b, and the vertical wind direction change blade small 21 is rotatably held by the support column 31 provided on the concave surface side of the large vertical wind direction change blade 13. When the air conditioner is stopped, the vertical wind direction change blade small 21 is moved to the vertical wind direction change blade 21. On the back side of the large 13 and on the front side of the center of rotation 26 provided on the support column 31, the concave shape of the small vertical wind direction changing blades 21 is arranged in the same direction as the large vertical wind direction changing blades 13. The change blade large 13 and the small blade 21 can be switched in the vertical position, and the surfaces facing each other can also be switched by rotation. The recesses face each other in the vicinity of the upper and lower ends of the opening of the air outlet. When the blown air is bent upward and downward, it is positioned outside the airflow, and the up / down airflow direction changing small blade 21 can be disposed so as to be positioned inside the airflow when bending the blown air upward and downward. Many Wind direction control with enabling such, it is possible to guide the air longer distance expansion and room for blowing angle of the wind in the lateral direction.

(Embodiment 3)
FIG. 10 is a cross-sectional view of an air conditioner according to a third embodiment of the present invention, FIG. 11 is a structural diagram of the up-and-down air direction changing blades of the air conditioner, and FIG. 12 shows an operating state of the air conditioner. FIG.

  In the following description, a description of the configuration and operation of the air conditioner 1 that overlaps the description of the first and second embodiments will be omitted.

  As shown in FIG. 10, 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. 11, the up / down wind 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. 12. Since the operation of the panel 11 is the same as that of the first and second embodiments, the description thereof will be omitted.

As in the first and second embodiments, 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 is farthest forward from the suction port 5. As shown in FIG. 12 (a), the up / down wind direction changing blade 41 is rotated downward by the drive motor 43 to open the lower portion of the outlet 6, and the up / down air direction changing blade 41 is directed upward from substantially horizontal. It moves to the position where it becomes an upward blowing state. 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. 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 from the suction port 5 to the position farthest forward, and 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 third 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 wind direction changing blade 40 and the vertical wind direction changing blade 41 rotate independently of each other, and the blade length can be extended and retracted by moving the inner blade 44 contained in and out of the rotation center 26 to the opposite side. Therefore, it is 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.
