[0033] This application provides an air guide device 100, such as... Figures 1 to 5As shown, the air guiding device 100 includes a first air guiding plate 110, a second air guiding plate 120, a rotating arm 130, a driving member 140, and a connecting rod 150; one end of the rotating arm 130 is connected to the first air guiding plate 110, and the rotating arm 130 is provided with a first rotating part 131 and a second rotating part 132. Along the length direction of the rotating arm 130, the second rotating part 132 is closer to the first air guiding plate 110 than the first rotating part 131; the second air guiding plate 120 is spaced apart from the first air guiding plate 110, and the second air guiding plate 120 is provided with a third rotating part 121 and a fourth rotating part 122 arranged at intervals along the length direction of the second air guiding plate 120; the connecting rod 150... The connecting rod 150 has a fifth rotating part 151 and a sixth rotating part 152 at its two ends, and the end of the connecting rod 150 with the sixth rotating part 152 is located between the first rotating part 131 and the second rotating part 132. The first rotating part 131 is connected to the output end of the driving member 140, which drives the rotating arm 130 to rotate the first air guide plate 110. The second rotating part 132 is rotatably connected to the fifth rotating part 151. The third rotating part 121 is rotatably connected to the air conditioner housing 200. The fourth rotating part 122 is rotatably connected to the sixth rotating part 152, so that the second air guide plate 120 can rotate synchronously with the first air guide plate 110. In other words, the first air guide plate 110 and the second air guide plate 120 can rotate synchronously through the cooperation of the driving member 140, the rotating arm 130, and the connecting rod 150, thereby simplifying the driving structure of the air guide device 100 and reducing its manufacturing cost.

[0034] The air guiding device 100 provided in this application embodiment is configured to connect the first rotating part 131 of the rotating arm 130 to the output end of the drive member 140. The drive member 140 can drive the rotating arm 130 to rotate the first air guiding plate 110. The second rotating part 132 of the rotating arm 130 is rotatably connected to the fifth rotating part 151 of the connecting rod 150. The third rotating part 121 of the second air guiding plate 120 is rotatably connected to the housing 200 of the air conditioner. The fourth rotating part 122 of the second air guiding plate 120 is rotatably connected to the sixth rotating part 152 of the connecting rod 150, so that the second air guiding plate 120 can rotate synchronously with the first air guiding plate 110. Thus, only one drive member 140 is needed to control the synchronous rotation of the first air guiding plate 110 and the second air guiding plate 120, which effectively reduces the manufacturing cost of the air guiding device 100.

[0035] In some embodiments of this application, the other end of the rotating arm 130 is bent towards the side of the first air guide plate 110 away from the second air guide plate 120 to form a bent portion 133, and both the first rotating portion 131 and the second rotating portion 132 are disposed on the bent portion 133. By bending the rotating arm 130 to form the bent portion 133, the rotation amplitude of the first air guide plate 110 and the second air guide plate 120 can be effectively increased, thereby improving the air guiding effect of the first air guide plate 110 and the second air guide plate 120. Of course, in other embodiments, the rotating arm 130 can also be other curved shapes.

[0036] In some embodiments of this application, the first rotating part 131 is a first shaft hole, and the driving member 140 is a motor. The motor shaft 141 of the motor passes through the first shaft hole so that the driving member 140 drives the rotating arm 130 to rotate around the central axis of the first shaft hole. Specifically, the side of the motor shaft 141 is provided with a first plane, and the hole wall of the first shaft hole is provided with a second plane. The motor shaft 141 is inserted into the first shaft hole, and the first plane and the second plane are in one-to-one correspondence to fit together, so as to realize the linkage connection between the motor shaft 141 and the rotating arm 130, so that the rotating arm 130 can rotate synchronously with the motor shaft 141, thereby driving the first air guide plate 110 to rotate.

[0037] Optionally, the number of first planes and second planes can be one or more, with the same number of each and they fitting together in a one-to-one correspondence. The specific number can be set according to actual needs. Preferably, the wall of the first shaft hole is provided with multiple second planes to form a polygonal hole, and the side of the motor shaft 141 is provided with multiple first planes to form a polygonal prism. The polygonal prism is inserted into the polygonal hole, and the multiple first planes and multiple second planes fit together in a one-to-one correspondence. For example, the wall of the first shaft hole is provided with six second planes to form a hexagonal hole, and the side of the motor shaft 141 is provided with six first planes to form a hexagonal prism. The hexagonal prism is inserted into the hexagonal hole, and the six first planes and six second planes fit together in a one-to-one correspondence.

[0038] Optionally, the second rotating part 132 is a first rotating shaft, and the fifth rotating part 151 is a second shaft hole. The first rotating shaft is rotatably inserted into the second shaft hole to achieve a rotatable connection between the second rotating part 132 and the fifth rotating part 151. Alternatively, the second rotating part 132 can be configured as a second shaft hole, and the fifth rotating part 151 as a first rotating shaft. The first rotating shaft is rotatably inserted into the second shaft hole, which also achieves a rotatable connection between the second rotating part 132 and the fifth rotating part 151.

[0039] Optionally, the sixth rotating part 152 is a third shaft hole, and the fourth rotating part 122 is provided with a third rotating shaft 123, which is rotatably inserted into the third shaft hole to achieve a rotatable connection between the fourth rotating part 122 and the sixth rotating part 152. Alternatively, the fourth rotating part 122 may be provided with a third shaft hole, and the sixth rotating part 152 may be a third rotating shaft 123, which is rotatably inserted into the third shaft hole, thus achieving a similar rotatable connection between the fourth rotating part 122 and the sixth rotating part 152.

[0040] In some embodiments of this application, the third rotating part 121 is provided with a fourth rotating shaft 160, the air conditioner housing 200 is provided with a connecting arm 210, the connecting arm 210 is provided with a fourth shaft hole, and the fourth rotating shaft 160 is rotatably inserted into the fourth shaft hole to realize the rotatable connection between the third rotating part 121 and the air conditioner housing 200.

[0041] Optionally, the fourth rotating shaft 160 is a component made of solid lubricating material. The third rotating part 121 is provided with a mating hole 124, and the fourth rotating shaft 160 is interference-fitted into the mating hole 124. One end of the fourth rotating shaft 160 is provided with a buckle 161, which is engaged in the fourth shaft hole, and the fourth rotating shaft 160 can rotate relative to the connecting arm 210 around its own central axis. By using a fourth rotating shaft 160 made of a fixed lubricating material and making the fourth rotating shaft 160 interference-fitted with the mating hole 124 on the third rotating part 121, friction and abnormal noise can be reduced compared to the solution of directly molding the fourth rotating shaft 160 integrally onto the third rotating part 121. By providing a buckle 161 at one end of the fourth rotating shaft 160, quick connection and disassembly of the fourth rotating shaft 160 and the connecting arm 210 can be achieved, which is beneficial to improving operating efficiency.

[0042] In some embodiments of this application, the fourth rotating shaft 160 includes a first mating portion 162 and a second mating portion 163 connected sequentially along the axial direction of the fourth rotating shaft 160. The first mating portion 162 is interference-fitted with the fourth shaft hole, and a latch 161 is provided at the end of the second mating portion 163 away from the first mating portion 162. A limiting portion 164 is provided between the first mating portion 162 and the second mating portion 163, and the two end faces of the fourth shaft hole abut against the limiting portion 164 and the latch 161, respectively. By providing the limiting portion 164 and making the two end faces of the fourth shaft hole abut against the limiting portion 164 and the latch 161, the second air guide plate 120 can be prevented from moving axially along the fourth rotating shaft 160, thereby improving the stability of the second air guide plate 120.

[0043] Optionally, the sidewall of the first mating part 162 is provided with a plurality of protrusions 165, which extend axially along the fourth rotating shaft 160 and are spaced apart circumferentially along the rotating shaft. By providing a plurality of protrusions 165 on the sidewall of the first mating part 162, the first mating part 162 can fit more tightly with the fourth shaft hole, preventing the first mating part 162 from disengaging from the fourth shaft hole.

[0044] Optionally, the end face of the protrusion 165 away from the limiting part 164 is configured as a guide slope 166. The guide slope 166 is used to guide the first mating part 162 into the fourth shaft hole, thereby improving the assembly efficiency of the first mating part 162 and the fourth shaft hole.

[0045] It is understood that in other embodiments, the third rotating part 121 may be provided with a fourth shaft hole, and the connecting arm 210 on the air conditioner housing 200 may be provided with a fourth rotating shaft 160. The fourth rotating shaft 160 on the connecting arm 210 may be rotatably inserted into the fourth shaft hole on the third rotating part 121, thus achieving a rotatable connection between the third rotating part 121 and the air conditioner housing 200.

[0046] In some embodiments of this application, the first air guide plate 110 has a first air guide position, a second air guide position, and a closed position during rotation, that is, the first air guide plate 110 can switch between the first air guide position, the second air guide position, and the closed position; the second air guide plate 120 has a third air guide position, a fourth air guide position, and an initial position during rotation, that is, the second air guide plate 120 can switch between the third air guide position, the fourth air guide position, and the initial position.

[0047] Specifically, when the first air guide plate 110 is in the closed position, the second air guide plate 120 is in the initial position; when the first air guide plate 110 is in the first air guide position, the second air guide plate 120 is in the third air guide position; when the first air guide plate 110 is in the second air guide position, the second air guide plate 120 is in the fourth air guide position.

[0048] This application also provides an air conditioner, such as... Figures 6 to 11 As shown, the air conditioner includes a housing 200 and the aforementioned air guide device 100. The specific structure of the air guide device 100 is as described in the above embodiment. An air outlet 201 is provided on the housing 200, and the air guide device 100 is disposed at the air outlet 201. The first air guide plate 110 and the second air guide plate 120 in the air guide device 100 are both rotatably connected to the housing 200, and the driving component 140 is fixed to the housing 200. Since this air conditioner adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0049] Specifically, the casing 200 is provided with an air duct 202 and a heat exchanger 300. The air inlet and air outlet of the air duct 202 are connected to the air inlet and air outlet 201, respectively. The heat exchanger 300 is located between the air inlet and the air inlet of the air duct 202. A fan 400 is provided in the air duct 202. When the fan 400 is running, it guides the airflow formed in the casing 200 to the air outlet 201 through the air duct 202. The second air guide plate 120 is rotatably set in the air duct 202 near the air outlet 201. The first air guide plate 110 is rotatably set at the air outlet 201 to open and close the air outlet 201. The first air guide plate 110 has a first connecting shaft 101 at both ends of its length direction, and the first connecting shaft 101 at both ends is rotatably connected to the housing 200; the second air guide plate 120 has a second connecting shaft 102 at both ends of its length direction, and the second connecting shaft 102 at both ends is rotatably connected to the housing 200.

[0050] Optionally, the air outlet 201 extends horizontally, and both the first air guide plate 110 and the second air guide plate 120 can rotate about an axis parallel to the extension direction of the air outlet 201. Specifically, as shown... Figures 9 to 11 As shown, the rotating arm 130 is assembled with the output end of the drive member 140 via the first rotating part 131 to form a driving point a. The second rotating part 132 of the rotating arm 130 is assembled with the fifth rotating part 151 of the first connecting rod 150 to form a rotating point b. The sixth rotating part 152 of the first connecting rod is assembled with the fourth rotating part 122 of the second air guide plate 120 to form a rotating point c. The third rotating part 121 of the second air guide plate 120 is assembled with the housing 200 to form a rotating point d. The rotating arm 130 is driven by the drive member 140 to rotate around the driving point a, so that the first air guide plate 110 rotates within a preset angle range to realize air guidance and the opening and closing of the air outlet 201. While the first air guide plate 110 rotates, the second air guide plate 120 will rotate synchronously around the rotating point d to realize air guidance.

[0051] In some embodiments of this application, the air conditioner has an upper air guide mode, a lower air guide mode, and a shutdown state. When the air conditioner is heating, it can operate in the lower air guide mode, and when the air conditioner is cooling, it can operate in the upper air guide mode.

[0052] Specifically, the first air guide plate 110 has an inner surface and an outer surface. The inner surface of the first air guide plate 110 refers to the side of the first air guide plate 110 facing the inside of the housing 200 when the air conditioner is in the off state, and the outer surface of the first air guide plate 110 refers to the side of the first air guide plate 110 facing the outside of the housing 200 when the air conditioner is in the off state. The inner surface of the first air guide plate 110 can guide the airflow from the air conditioner. One end of the rotating arm 130 is connected to the inner surface of the first air guide plate 110; the second The air guide plate 120 has an air guiding surface and a leeward surface. The air guiding surface of the second air guide plate 120 refers to the side of the second air guide plate 120 facing the first air guide plate 110 when the air conditioner is turned off. The air guiding surface of the second air guide plate 120 refers to the side of the second air guide plate 120 away from the first air guide plate 110 when the air conditioner is turned off. The air guiding surface of the second air guide plate 120 can guide the airflow of the air conditioner. The third rotating part 121 and the fourth rotating part are both disposed on the air guiding surface of the second air guide plate 120.

[0053] The following descriptions, with reference to the accompanying diagrams, explain the air conditioner's top airflow mode, bottom airflow mode, and off state:

[0054] like Figure 9 As shown, the air conditioner is configured such that when the air conditioner is in the off state, the first air guide plate 110 is in the closed position and the second air guide plate 120 is in the initial position. At this time, the inner surface of the first air guide plate 110 faces the rear upper part of the housing 200 and the air outlet 201 is completely closed, and the air guiding surface of the second air guide plate 120 faces the front lower part of the housing 200.

[0055] like Figure 10 As shown, the air conditioner is configured such that, in the downward airflow mode, the first air guide plate 110 is in the first airflow position and the second air guide plate 120 is in the third airflow position. At this time, the inner surface of the first air guide plate 110 faces the front upper part of the housing 200, and the airflow guide surface of the second air guide plate 120 faces the rear lower part of the housing 200, so that the airflow is sent downward (i.e. downward airflow).

[0056] like Figure 11 As shown, the air conditioner is configured such that, in the upward airflow mode, the first air guide plate 110 is in the second airflow position and the second air guide plate 120 is in the fourth airflow position. At this time, the inner surface of the first air guide plate 110 faces the upper part of the housing 200, and the airflow guide surface of the second air guide plate 120 faces the lower part of the housing 200, so that the airflow is sent upward (i.e., upward airflow).
