Fig. 1 is a schematic structural view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, fig. 2 is a schematic structural view of an air guide plate 50 according to an embodiment of the present invention, fig. 3 is an exploded schematic view of the air guide plate 50 shown in fig. 2, fig. 4 is an enlarged view of a point a of fig. 3, and fig. 5 is a schematic structural view of an end portion structure of an outer panel 51 and an installation arm 55.

As shown in fig. 1 to 5, the air deflector 50 of the embodiment of the present invention is rotatably installed at the air outlet 12 of the indoor unit of the wall-mounted air conditioner for guiding the air outlet direction of the air outlet 12. The outlet 12 of the wall-mounted air conditioning indoor unit is generally elongated with its longitudinal direction extending in the horizontal transverse direction X, so that the air deflector 50 may be elongated with its longitudinal direction parallel to the longitudinal direction X of the outlet 12, and the axis X of rotation of the air deflector 50 is parallel to the longitudinal direction X.

As shown in fig. 2-5, the air deflection plate 50 of an embodiment of the present invention may generally include an outer plate body 51, an inner plate body 52, and at least one mounting arm 55. The inner panel 52 and the outer panel 51 are disposed such that the side facing each other is an inner side and the side facing the outside is an outer side. When the air guide plate 50 is in a state of closing the outlet 12, the outer side of the outer plate 51 faces the outside of the casing 10, and the outer side of the inner plate 52 faces the inside of the casing 10.

The inner side of the outer plate body 51 has at least one mounting boss, for example three mounting bosses 512, 513, 514 are provided as shown in fig. 4 and 5. Each of the mounting bosses 512, 513, 514 is elongated and extends in the longitudinal direction (X direction) of the outer plate 51. The provision of the mounting bosses 512, 513, 514 reinforces the structure of the outer plate body 51. And, a positioning hole 5141 is formed on one of the mounting bosses 514.

The inner panel 52 covers the inner side of the outer panel 51 with a gap from the outer panel 51. At least one abdicating hole 520 is formed on the inner plate body 52. The number of the relief holes 520 is the same as the number of the mounting arms 55.

The number of mounting arms 55 is typically two, as shown in fig. 2. Of course, the number of mounting arms 55 may also be three or more. The end of each mounting arm 55 has a positioning block 555, and the positioning block 555 has a plurality of catching projections 5551 thereon. The end of each mounting arm 55 passes through one of the yielding holes 520, and the positioning block 555 extends into the positioning hole 5141, so that the retaining protrusion 5551 is retained at the edge of the positioning hole 5141, thereby positioning the position of the mounting arm 55. The other end of the mounting arm 55 is rotatably connected to the casing 10 of the wall-mounted air conditioning indoor unit to rotatably connect the air guide plate 50.

In the embodiment of the present invention, the inner plate 52 and the outer plate 51 form a double-layer structure, and a gap is provided between the two layers of plates, so that the air guide plate 50 forms a hollow structure, making its structural strength larger and the deformation resistance stronger. The hollow structure between the inner plate 52 and the outer plate 51 also reduces the risk of condensation on the leeward side of the air deflector 50 in the cooling mode. In addition, the mounting arm 55 passes through the offset hole 520 of the inner plate 52 to be connected to the outer plate 51, so that the outer plate 51 is designed as a base member having the greatest strength, and both the inner plate 52 and the mounting arm 55 are mounted to the outer plate 51, thereby stabilizing the overall structure of the air guide plate 50. In addition, the positioning and clamping of the mounting arm 55 are simultaneously realized by the positioning block 555, and the design is very ingenious.

In some embodiments, the inner plate 52 and the outer plate 51 may be made of plastic by a die extrusion process. Specifically, the outer plate body 51 may be made of a PC + ABS material, and the inner plate body 52 may be made of a PC + GF material. The plastic part manufactured by the extrusion process has small difference of heat conduction coefficients, and compared with the injection molding process, the internal stress is reduced, the deformation of the air deflector 50 is improved, and the disassembly and assembly structure is simpler. The present embodiment designs the mounting arm 55 as a separate component from the inner plate 52 and the outer plate 51, which facilitates the manufacture of the inner plate 52 and the outer plate 51 through a die extrusion process.

Fig. 6 is an enlarged sectional view of the air guide plate 50 shown in fig. 2 in an exploded state, and the angle thereof is appropriately adjusted; fig. 7 is an enlarged sectional view of the air guide plate 50 shown in fig. 6 in an assembled state.

As shown in fig. 4 to 7, the end of the mounting arm 55 may further have two clip portions 551, which are respectively located at both sides of the positioning block 555 and spaced apart from the positioning block 555 so as to be respectively clipped at both sides of the mounting boss 514 in the width direction, so that the position of the mounting arm 55 is more stable, referring to fig. 4, 5 and 7.

Further, as shown in fig. 5 and 6, the inner side surface of the outer plate 51 may have two snap ribs 5132 and 515 extending in the longitudinal direction thereof, and edges of the two snap ribs 5132 and 515 may be bent in a direction approaching each other to form a burring shape. Each clip plate portion 551 has a plurality of first hooks 552 on its outer side for hooking onto the corresponding hooking ribs 5132, 515, as shown in fig. 7. This further prevents the mounting arm 55 from disengaging from the outer plate 51. Specifically, the snap ribs 5132 may extend from the sides of the mounting boss 513.

By the design, the freedom degree of the mounting arm 55 for rotation relative to the outer plate body 51 is effectively restricted, and the mounting arm is effectively clamped around the periphery of the positioning block 555, so that the position of the mounting arm is more stable.

In some embodiments of the present invention, as shown in fig. 3 and 4, the air guiding plate 50 may further include two end caps 53. The two end caps 53 are respectively used for sealing the gap between the ends of the outer plate body 51 and the inner plate body 52, so as to form a sealed cavity between the outer plate body 51 and the inner plate body 52 and prevent cold air or hot air from entering the cavity.

To mount the end cap 53, each of the mounting bosses 512, 513, 514 may be hollow with both ends open, and may be provided with a fastening hole 510. A plurality of second hooks 531 may extend from the inner side of each end cap 53, and each second hook 531 extends into the mounting bosses 512, 513, 514 and hooks into the corresponding fastening hole 510. In this way, the end cap 53 and the outer panel 51 are fixedly connected to each other.

Further, as shown in fig. 4, a plurality of positioning ribs 532 may extend from an inner side of each end cap 53, and two sides of each positioning rib 532 respectively abut against the inner side surface of the outer plate 51 and the inner side surface of the inner plate 52, so as to further clamp the positioning ribs 532 of the end cap 53 by using the outer plate 51 and the inner plate 52, thereby making the position of the end cap 53 more stable and making the sealing between the end cap 53 and the inner plate 52 and the outer plate 51 more tight.

In some embodiments of the present invention, as shown in fig. 6 and 7, a plurality of elongated reinforcing ribs 522 extending along the length direction of the inner plate 52 may extend from the inner side surface of the inner plate 52, and each reinforcing rib 522 is attached to the side surface of one of the mounting bosses 512, 513, so as to position the inner plate 52 in the width direction, as shown in fig. 7. The reinforcing ribs 522 also serve to reinforce the strength of the inner panel body 52. After the inner plate 52 is mounted in place, the reinforcing ribs 522 also abut against the inner side surface of the outer plate 51, and play a role in supporting the inner plate 52 and the outer plate 51, as shown in fig. 7, so as to prevent the inner plate 52 and the outer plate 51 from being deformed inwards.

As shown in fig. 6 and 7, two widthwise edges of the outer plate 51 may be bent inward to form two flanges 511, and two widthwise edges of the inner plate 52 may be respectively engaged with the inner sides of the two flanges 511, so as to achieve engagement between the inner plate 52 and the outer plate 51. Specifically, two widthwise edges of the inner plate 52 are bent inward to form flanges 521 to be received inside the flanges 511.
