  An embodiment according to the present invention will be described with reference to the drawings. In this embodiment, an air conditioner is used as an air conditioner, and a wind direction changing device is mounted on the air conditioner.

  The indoor unit of an air conditioner is shown in FIGS. The indoor unit includes a heat exchanger 1 and an indoor fan 2, which are housed in a cabinet 3. The cabinet 3 is formed in a box shape having a depth longer than the height, and has a curved surface from the front surface to the bottom surface. A suction port 4 is formed on the upper surface of the cabinet 3, and an outlet 5 is formed on the curved surface.

  An air passage 6 extending from the suction port 4 to the blowout port 5 is formed inside the cabinet 3, and the heat exchanger 1 and the indoor fan 2 are disposed in the air passage 6. A filter 7 is disposed between the suction port 5 and the heat exchanger 1, and dust is removed from indoor air sucked from the suction port 4. A cleaning device 8 for cleaning the filter 7 is provided.

  The cleaning device 8 moves the filter 7 in the cabinet 3 to pass through the dust removing unit 9, and the dust removing unit 9 removes dust attached to the filter 7. A guide path 10 that is curved in a U shape in a side view is formed on the front side in the cabinet 3, and a moving unit including a motor and a gear reciprocates the filter 7 along the guide path 10. In the dust removing unit 9, the rotating brush 11 scrapes off dust from the passing filter 7, and a suction fan causes air to flow in a direction substantially parallel to the filter 7 (left and right direction), and the scraped dust is sucked and discharged. To do.

  An air guide panel 20 that opens and closes the air outlet 5 is provided on the curved surface of the cabinet 3. As shown in FIGS. 2 to 4, the wind guide panel 20 can be opened both up and down, and an opening / closing mechanism for moving the wind guide panel 20 to open and close is provided.

As shown in FIGS. 3 and 4, when the wind guide panel 20 opens and closes, the end of the wind guide panel 20 enters this gap. The wind guide panel 20 can rotate smoothly without hitting the cabinet 3. Further, when the wind guide panel 20 is opened to the maximum in the upper opening or the lower opening, the front and rear ends of the wind guide panel 20 are blown out so that the wind guide panel 20 contacts the cabinet 3. Prevents the wind from leaking. In particular, in the case of cold air, condensation on the bottom surface side of the cabinet 3 can be prevented.

  Thus, the outer surface of the wind guide panel 20 constitutes a smooth curved surface extending from the front surface to the bottom surface of the cabinet 3. That is, the wind guide panel 20 is a member constituting a part of the front surface of the cabinet 3. In other words, a part of the panel of the cabinet 3 is used as the wind guide panel 20. Thereby, the wind guide panel 20 becomes a long panel having a long overall length as compared with the louver employed in the conventional air conditioner.

  The wind guide panel 20 opens in either the upper or lower direction by rotating in different directions around the upper and lower axes. As shown in FIG. 4, the air guide panel 20 opens downward around the lower shaft 22 during the cooling operation. In this downward opening posture, the wind guide panel 20 is connected to the lower wall of the air outlet 5, and a long nozzle is formed by the air guide panel 20 and the upper wall of the air outlet 5. The wind guide panel 20 guides the cool air obliquely upward, and the cool air blows out along the ceiling.

  As shown in FIG. 3, it opens upward around the upper shaft 23 during heating operation. In this upward-opening posture, the air guide panel 20 shields the front of the air outlet 5, suppresses the warm air blown forward, and guides the warm air toward the floor surface. Even at the initial stage of the cooling operation, the air guide panel 20 is in the upwardly open posture, and the cool air is blown out in the direction of the floor surface to perform rapid cooling. As shown in FIG. 2, the wind guide panel 20 is closed when the operation is stopped, covers the air outlet 5, and is integrated with the cabinet 3.

  The air outlet 5 is provided with a wind direction changing device 12 and an auxiliary louver (not shown). The wind direction changing device 12 changes the wind direction in the left-right direction by changing the angle of the wind direction plate 24 in the left-right direction. The auxiliary louver changes the vertical direction according to the posture of the wind guide panel 20 and changes the vertical direction while rectifying the blown wind.

  As shown in FIGS. 5 to 8, the wind direction changing device 12 includes a plurality of wind direction plates 24, a substrate 13 to which the wind direction plates 24 are attached, and an interlocking rod 14 that links and links the wind direction plates 24. .

  As shown in FIG. 5, the substrate 13 is formed in an elongated plate shape. When the substrate 13 is installed in the air outlet 5, the length direction of the substrate 13 is aligned with the left-right direction A of the air outlet 5, that is, The substrate 13 is set so that the width direction B of the substrate 13 is parallel to the flow direction C of the air flowing through the outlet 5.

  In the present embodiment, the wind direction plate 24 is divided into a right wind direction plate group 25 located in the right half of the substrate 13 and a left wind direction plate group 26 located in the left half of the substrate 13. In addition, the interlocking rods 14 that are connected to and interlocked with the wind direction plate 24 are separately provided. Thereby, each wind direction board group 25, 26 can adjust the angle of the wind direction board 24 independently, and can change a wind direction to right and left.

  Motors 27 are provided on the back surfaces of both ends of the substrate 13 in the left-right direction. A drive arm 28 is connected to the motor 27 via a speed reducer (not shown) so that the motor 27 can swing around the rotation shaft 28 b of the drive arm 28. A pin 28 a is formed at the tip of the drive arm 28, the pin 28 a is rotatably connected to the interlocking rod 14, and the interlocking rod 14 moves in the left-right direction when the drive arm 28 swings.

  As shown in FIGS. 8 and 9, the wind direction plate 24 includes a blade portion 15 and a support portion 16 that supports the blade portion 15 and is fixed to the substrate 13, and the blade portion 15 includes a hard portion 15a, The flexible part 15b is formed on one side of the hard part 15a and connected to the support part 16. The blade portion 15 is integrally formed of polypropylene of the same synthetic resin for both the hard portion 15a and the flexible portion 15b. The thickness t1 of the hard portion 15a is 1.0 mm, and the thickness t2 of the flexible portion 15b is 0.3 mm. It is formed to become.

  Thus, the flexible part 15b is provided with flexibility by forming it thinner than the hard part 15a. The wind direction plate 24 is fixed on the substrate 3 along the air flow direction C so that the support portion 16 is oriented upstream and the hard portion 15a is oriented downstream. The support portion 16 has the same thickness as the hard portion 15a and does not bend like the flexible portion 15b. The flexible portion 15b is required to be flexible enough to bend by the force of the interlocking rod 14, and in addition to the above configuration, for example, a hard material constituting the hard portion 15a Can be made of another soft material.

  On the other hand, since the wind direction plate 24 is formed of synthetic resin, the distance X from the support portion 16 to the shaft portion 29a is likely to vary. In particular, in the case where the flexible portion 15b is provided as in the present embodiment, the tendency becomes strong.

  In the wind direction plate 24, a rectangular through hole 29 is formed slightly below the central portion of the hard portion 15a, and the interlocking rod 14 is locked at a position near the support portion 16 in the through hole 29. A shaft portion 29a is formed as a locking portion. The shaft portion 29a is formed so that the axial direction D thereof is parallel to the boundary line E between the hard portion 15a and the flexible portion 15b.

  And the flange part 29b is formed in the both ends of the axial part 29a. That is, a stepped portion is formed between the inner wall of the through hole 29 and the shaft portion 29a by the flange portion 29b. As a result, the interlock rod 14 and the through hole wall are prevented from coming into direct contact with each other, and as described above, the interlock rod 14 and the drive arm 28 are also prevented from coming into direct contact with each other. The wind direction can be changed.

  When the interlocking rod 14 connected to the shaft portion 29a of the wind direction plate 24 moves in the left-right direction, the flexible portion 15b curves in the left-right direction and continues as the support portion 16 and the entire blade portion 15 as shown in FIG. A gentle curved surface is formed, whereby the direction of air flow can be changed smoothly.

  As shown in FIGS. 11 and 12, the base portion 16 a of the support portion 16 is formed so as to slide and fit in one direction with respect to the substrate 13. Specifically, a plurality of cut portions 17 for fixing the wind direction plate 24 are formed at one end portion in the width direction B of the substrate 13, and the side on which the cut portions 17 are formed is in the air flow direction C. The board | substrate 13 is set to the blower outlet 5 so that it may become an upstream.

  On the other hand, the base portion 16a of the support portion 16 is an elongated block shape having a length substantially the same as the length of the notch portion 17, and groove portions 19 are formed on both sides thereof so that the side walls of the notch portion 17 are slidably fitted. Shaped. The base portion 16 a is fitted to the substrate 13 by inserting and sliding the groove portion 19 into the cut portion 17 from the side of the substrate 13.

  FIG. 13 is a plan view showing a state in which the interlocking rod 14 is engaged with the wind direction plate 24. In the drawing, the part surrounded by a circle is partially enlarged. As shown in the figure, the interlocking rod 14 is formed in an elongated flat bar shape, and has a substantially L shape in which one end portion in the length direction is bent in the width direction. In the interlocking rod 14, a connecting hole 30 is formed at the bent tip. A plurality of shaft holes 31 are formed at one end of the interlocking rod 14 in the width direction along the length direction of the interlocking rod 14.

  The shaft hole 31 has an elongated hole shape that is elongated in a direction (width direction) orthogonal to the length direction of the interlocking rod 14. A pin 28 a formed at the tip of the drive arm 28 is connected to the connection hole 30, and a plurality of shaft holes 31 formed at one end in the width direction of the interlocking rod 14 are connected to the shaft portion of each wind direction plate 24. 29a is engaged.

  In the present embodiment, the interlocking rod 14 is provided with a cut portion 32 that reaches the shaft hole 31. When connecting the interlocking rod 14 to the drive arm 28 and the shaft portion 29a, the connecting hole 30 and the shaft hole 31 are connected to the pin 28a and the shaft portion in a state where the interlocking rod 14 is inserted into the through hole 29 of each wind direction plate 24. Just push in towards 29a. Thereby, the interlocking rod 14 can be easily engaged with the drive arm 28 and the shaft portion 29a.

  In the present embodiment, the interlocking rod 14 is provided with a cut portion 32 that reaches the shaft hole 31. For example, a pin is provided as a shaft portion 29 a on the wind direction plate 24 and the shaft hole 31 is provided with a pin. May be formed into a long hole shape or a round hole shape without providing the notch 32, and a pin may be inserted into the shaft hole 31 to engage them.

  In this case, it is preferable that a stopper having a substantially hemispherical shape with a maximum diameter portion larger than the pin diameter is formed at the tip of the pin to prevent the interlocking rod 14 from falling off the pin. When the pin is engaged with the shaft hole 31, the pin may be forcibly fitted into the shaft hole with the stopper at the top. In the present embodiment, the shape of the connecting hole 30 is a C shape, but it may be a round hole shape.

  In the present embodiment, all the shaft holes 31 formed in the interlocking rod 14 have a long hole shape, but as a second aspect, as shown in FIG. In the interlocking rod 14 in which is formed, the shape of the shaft hole 31a located on the other end in the length direction is a round hole shape in which the shaft portion 29a is rotatably fitted, and the other shaft hole 31b is a long hole shape. It is also possible.

  In the said aspect, when one 31a of the some shaft holes 31 formed in the interlocking rod 14 is made into a round hole shape, by the play between the shaft hole 31b and the shaft part 29a, the interlocking rod 14 It becomes possible to prevent rattling.

  In the second aspect, it is preferable that the wind direction plate 24a with which the shaft hole 31a is engaged can be adjusted in position by sliding the support portion 16 in the width direction B of the substrate 13.

  That is, in the second mode shown in FIG. 14, the posture of the interlocking rod 14 is determined by the distance X of the wind direction plate 24a. Therefore, for example, when the distance X of the wind direction plate 24a happens to be short, the distance between the shaft hole and the support portion in the other shaft hole 31b is also shortened. If it does so, in the wind direction board 24 with the long distance X, there exists a possibility that the axial part 29a may contact the axial hole 31b and bend.

  Therefore, as described above, by adjusting the position of the support portion 16 of the wind direction plate 24a, the distance between the shaft hole and the support portion in each shaft hole 31b is adjusted, and the direction of the wind direction plate 24 becomes uneven. Can be appropriately prevented.
