[0043] The embodiments of the present disclosure provide an air conditioner, as shown in Figures 1 to 3

[0044] In some embodiments, the air conditioner includes a rack set for driving the air deflector 10 to move.

[0045] ​The air conditioner provided by the embodiments of the present disclosure is a uniform air supply air conditioner. The rack set can drive the air deflector 10 to move from the closed state to the air guiding position outside the air conditioner, guide the indoor air to the air outlet, mix with the air blown out from the heat exchanger, and then blow to the user. In this way, the air blown out from the heat exchanger will not directly blow to the user, and the comfort of the user is improved. Moreover, the air guiding channel is arranged outside the air conditioner, which will not cause the loss of the air supply amount of the air conditioner, and the air guiding device does not need to be arranged outside the casing of the air conditioner, so that the structure of the air conditioner is simplified.

[0046] Optionally, a flow guide plate is arranged in the air outlet of the air conditioner to guide the air up and down.

[0047] It can be understood that the air deflector 10 is used to guide the air, and can guide the indoor air to the air outlet. The flow guide plate arranged in the air outlet can guide the air up and down to meet different requirements of cooling or heating. The air blown out from the flow guide plate and the indoor air guided to the air outlet through the air deflector 10 are mixed at the air outlet and then blown to the user, so that the uniform air supply effect is achieved.

[0048] Optionally, the air deflector 10 is in a horizontal state when it is in the air guiding position, and the air guiding position is located below the air conditioner, and the upper edge of the air deflector 10 is located behind the air outlet of the air conditioner.

[0049] When the air deflector 10 is in the horizontal state, the upper edge of the air deflector 10 is located below the air conditioner and behind the air outlet, so that the air deflector 10 will not block the air outlet when the air conditioner blows air downward, and the cooling or heating effect of the air conditioner will not be affected. Moreover, the air blown out from the heat exchanger will not directly blow to the air deflector, and condensation will not be generated on the air deflector.

[0050] Optionally, when the air deflector 10 is in the horizontal state, the distance between the air deflector 10 and the lower casing of the air conditioner is greater than 30 mm.

[0051] In the embodiments of the present disclosure, the air deflector 10 is used to guide the air. When the air conditioner is turned on, the air deflector 10 is stretched from the closed state to the intermediate position, and then rotated to the horizontal state. The air deflector 10 will not be rotated or flipped again when it is in the horizontal state. When the air deflector 10 is in the horizontal state, the air deflector 10 has a preset distance from the lower casing of the air conditioner. It can be understood that when the preset distance is small, the air deflector 10 and the lower casing of the air conditioner may generate a certain air guiding noise, and the air guiding effect cannot be achieved. The preset distance is set to be greater than 30 mm, so that the air deflector 10 can have a good air guiding effect, and no other noise will be generated during the air guiding process. For example, the preset distance can be 40 mm, 50 mm, 60 mm, or 100 mm, etc.

[0052] The rack set for driving the air deflector 10 to move is shown in Fig. 1. Figures 4 to 10

[0053] In some embodiments, the rack set for driving the air deflector 10 to move includes a first arc-shaped rack 20 and a second arc-shaped rack 30, one end of the first arc-shaped rack 20 is hingedly connected with the air deflector 10, one end of the second arc-shaped rack 30 is slidingly connected with the air deflector 10, and the first arc-shaped rack 20 and the second arc-shaped rack 30 are slidingly connected with each other; wherein a limiting mechanism is arranged between the first arc-shaped rack 20 and the second arc-shaped rack 30, the limiting mechanism is used to limit the relative movement between the first arc-shaped rack 20 and the second arc-shaped rack 30, so that the rack set drives the air deflector 10 to be tightened from the air guiding position outside the air conditioner to the closed state under the driving of external force.

[0054] In the embodiments of the present disclosure, the rack set for driving the air deflector 10 to move includes a first arc-shaped rack 20 and a second arc-shaped rack 30, one end of the first arc-shaped rack 20 is hingedly connected with the air deflector 10, one end of the second arc-shaped rack 30 is slidingly connected with the air deflector 10, and the first arc-shaped rack 20 and the second arc-shaped rack 30 are slidingly connected with each other. In this way, the rack set can drive the air deflector 10 to move synchronously or relatively, so that the air deflector 10 can move from the closed state to the air guiding position outside the air conditioner, guide the indoor air flow to the vicinity of the air outlet, and mix with the air flow blown out from the heat exchanger for air supply, thereby improving the softness of the air supply of the air conditioner. Moreover, the air conditioner can realize air guiding by using the air deflector 10, without the need to additionally arrange an air guiding device outside the casing, thereby simplifying the structure of the air conditioner. Meanwhile, a limiting mechanism is arranged between the first arc-shaped rack 20 and the second arc-shaped rack 30, the limiting mechanism can limit the relative movement between the two arc-shaped racks, so that the first arc-shaped rack 20 and the second arc-shaped rack 30 will not be out of gear during the process that the air deflector 10 returns to the closed state from the air guiding position, thereby enabling the air deflector 10 to be tightened in the closed state, and preventing the air deflector 10 from generating a gap with the air conditioner.

[0055] Optionally, the limiting mechanism includes a limiting slot 25 and a limiting column 36, the limiting slot 25 is arranged on the side of the first arc-shaped rack 20 along the length direction of the first arc-shaped rack 20, and the limiting column 36 is arranged on the side of the second arc-shaped rack 30 opposite to the first arc-shaped rack 20, and is slidingly arranged in the limiting slot 25.

[0056] As shown in Fig. 1, Figure 4 ​As shown, the first arc-shaped rack 20 and the second arc-shaped rack 30 are arranged side by side and abut each other. The side of the first arc-shaped rack 20 is provided with a limiting groove 25, and the corresponding side of the second arc-shaped rack 30 is provided with a limiting column 36. Optionally, the limiting groove 25 is in an oblong shape, and the limiting column 36 is in a cylindrical shape. The outer diameter of the limiting column 36 is equal to the width of the limiting groove 25, so that the limiting column 36 can slide along the limiting groove 25 to limit the movement track of the second arc-shaped rack 30 according to the track of the limiting groove 25. In the embodiment of the present disclosure, the limiting groove 25 is arranged along the length direction of the first arc-shaped rack 20, and the limiting groove 25 has an upper end away from the air deflector 10 and a lower end close to the air deflector 10.

[0057] Optionally, the air deflector 10 is arranged horizontally below the air conditioner when the air deflector 10 is in the air guiding position.

[0058] In the embodiment of the present disclosure, the movement track of the air deflector 10 is first extended from the closed state to the intermediate position, and then rotated to the air guiding position. When the air deflector 10 is in the closed state and the intermediate position, the limiting column 36 is located at the upper end of the limiting groove 25. When the air deflector 10 is rotated from the intermediate position to the air guiding position, the limiting column 36 slides from the upper end of the limiting groove 25 to the lower end of the limiting groove 25. That is, in this process, the second arc-shaped rack 30 moves relative to the first arc-shaped rack 20. In the process of retracting the air deflector 10 from the air guiding position, the limiting column 36 first slides from the lower end of the limiting groove 25 to the upper end of the limiting groove 25, and then the limiting column 36 drives the first arc-shaped rack 20 to move. When the limiting column 36 moves to the upper end of the limiting groove 25, the teeth on the first arc-shaped rack 20 and the second arc-shaped rack 30 can correspond to the preset position, avoiding the misalignment between the two, and thus the first arc-shaped rack 20 and the second arc-shaped rack 30 synchronously drive the air deflector 10 to return to the closed state, and the air deflector 10 is retracted in the closed state. Through the above-mentioned limiting mechanism, the precision of the rack set driving the air deflector 10 to move is improved.

[0059] Optionally, the length of the limiting groove 25 is equal to an integer multiple of the tooth width of the teeth on the second arc-shaped rack 30.

[0060] It can be understood that the length of the limiting groove 25 is the relative movement track of the second arc-shaped rack 30 relative to the first arc-shaped rack 20. In the process of retracting the air deflector 10, the second arc-shaped rack 30 first moves relative to the first arc-shaped rack 20, and then the two synchronously move to retract the air deflector 10. The length of the limiting groove 25 is set to be an integer multiple of the tooth width of the teeth, so that after the relative movement of the first arc-shaped rack 20 and the second arc-shaped rack 30, the teeth on the two can correspond to the preset position, and misalignment does not occur.

[0061] Optionally, the first side surface of the first arc-shaped rack 20 is in abutment with the second side surface of the second arc-shaped rack 30, the first side surface is provided with a sliding cavity 23 recessed inwardly, and the second side surface is provided with a sliding strip 34 slidingly arranged in the sliding cavity 23.

[0062] In the embodiments of the present disclosure, the first arc-shaped rack 20 and the second arc-shaped rack 30 are arranged side by side and are slidingly connected. The upper surfaces of the first arc-shaped rack 20 and the second arc-shaped rack 30 are both provided with tooth portions, the first side surface of the first arc-shaped rack 20 opposite to the second arc-shaped rack 30 is provided with a sliding cavity 23, and correspondingly, the second side surface of the second arc-shaped rack 30 is provided with a sliding strip 34. When the first arc-shaped rack 20 and the second arc-shaped rack 30 move relatively, the sliding strip 34 slides in the sliding cavity 23. That is, in the process that the deflector 10 moves from the middle position to the horizontal state, the first arc-shaped rack 20 stops moving, and the second arc-shaped rack 30 moves relative to the first arc-shaped rack 20. That is, the sliding strip 34 of the second arc-shaped rack 30 slides in the sliding cavity 23 of the first arc-shaped rack 20, so that the second arc-shaped rack 30 continues to be driven by the driving element in the preset direction. The first arc-shaped rack 20 and the second arc-shaped rack 30 are slidingly connected in the above manner, so that when the second arc-shaped rack 30 is driven by the driving element, the second arc-shaped rack 30 can still move along the preset track, the movement of the second arc-shaped rack 30 off the track is prevented, and the reliability of the rack set of the present application is improved.

[0063] Optionally, the bottom surface of the sliding cavity 23 extends toward the side close to the second arc-shaped rack 30 and wraps the lower surface of the second arc-shaped rack 30. In this way, the sliding strip 34 on one side of the second arc-shaped rack 30 is in the sliding cavity 23, and the lower surface of the second arc-shaped rack 30 is in abutment with the bottom surface of the sliding cavity 23, further limiting the movement direction of the second arc-shaped rack 30 relative to the first arc-shaped rack 20, and improving the reliability of the movement of the second arc-shaped rack 30.

[0064] Optionally, the center of the circle in which the first arc-shaped rack 20 is located and the center of the circle in which the second arc-shaped rack 30 is located coincide on the same projection plane.

[0065] It can be understood that the first arc-shaped rack 20 and the second arc-shaped rack 30 are both arc-shaped, which can shorten the movement stroke of the deflector 10 from the closed state to the position below the air conditioner, so that the deflector 10 can reach the preset horizontal state as soon as possible. Moreover, the arc-shaped rack occupies less space on the side of the indoor unit of the air conditioner, which can adapt to more types of air conditioners.

[0066] The center of the circle where the first arc-shaped rack 20 is located and the center of the circle where the second arc-shaped rack 30 is located coincide on the same projection plane, that is, the first arc-shaped rack 20 and the second arc-shaped rack 30 have the same bending degree. In this way, the first arc-shaped rack 20 and the second arc-shaped rack 30 can be driven by the same driving element to first synchronously drive the air deflector 10 to extend out of the air conditioner, and then the first arc-shaped rack 20 and the second arc-shaped rack 30 slide to generate relative movement, thereby driving the air deflector 10 to rotate to a horizontal state.

[0067] Optionally, the upper surface of the first arc-shaped rack 20 is provided with the first tooth portion 21 and the toothless portion 26, and the upper surface of the second arc-shaped rack 30 is provided with the second tooth portion 31. The first tooth portion 21 is arranged close to the air deflector 10, and the starting end of the toothless portion 26 is connected to the end of the first tooth portion 21. The effective length of the second tooth portion 31 is equal to the sum of the effective length of the first tooth portion 21 and the effective length of the toothless portion 26.

[0068] As shown in FIG. 2, the upper surface of the first arc-shaped rack 20 is sequentially provided with the first tooth portion 21 and the toothless portion 26. Figure 5 Optionally, the effective length of the first tooth portion 21 can be the length of the tooth portion engaged by the driving element during the process that the air deflector 10 extends from the closed state to the intermediate position. Optionally, the effective length of the toothless portion 26 can be the length of the tooth portion engaged by the driving element during the process that the air deflector 10 rotates from the intermediate position to the air guiding position. In order to better prevent the first arc-shaped rack 20 and the second arc-shaped rack 30 from being out of gear during the return process of the air deflector 10, the effective length of the toothless portion 26 can be further lengthened and the effective length of the first tooth portion 21 can be further shortened. Optionally, the effective length of the first tooth portion 21 can also be the length of the tooth portion engaged by the driving element during the process that the air deflector 10 moves from the closed state to the inclined position. Optionally, the effective length of the toothless portion 26 can also be the length of the tooth portion engaged by the driving element during the process that the air deflector 10 moves from the following inclined position to the air guiding position.

[0069] As shown in FIG. 2, the upper surface of the first arc-shaped rack 20 is sequentially provided with the first tooth portion 21 and the toothless portion 26. Figure 6 As shown in FIG. 2, the upper surface of the first arc-shaped rack 20 is sequentially provided with the first tooth portion 21 and the toothless portion 26.

[0070] In the embodiments of the present disclosure, the first arc-shaped rack 20 and the second arc-shaped rack 30 are in transmission connection with the same driving element. Optionally, the driving element includes a gear 40. The gear 40 is engaged with the first arc-shaped rack 20 or the second arc-shaped rack 30, thereby driving the air deflector 10 to extend or rotate.

[0071] Understandably, the effective length of the second tooth 31 is greater than the effective length of the first tooth 21, allowing the air guide plate 10 to move along the following trajectory. When the air guide plate 10 is in the closed state, the gear 40 meshes synchronously with the first arc-shaped rack 20 and the second arc-shaped rack 30, causing the air guide plate 10 to extend to the middle position. When the air guide plate 10 is in the middle position, the gear 40 can mesh to the end of the first tooth 21, the first arc-shaped rack 20 stops moving, and the gear 40 continues to mesh with the second arc-shaped rack 30. The second arc-shaped rack 30 moves relative to the first arc-shaped rack 20, causing the air guide plate 10 to rotate to a horizontal state for airflow.

[0072] Optionally, the length of the toothless portion 26 is greater than or equal to the effective length of the first tooth portion 21.

[0073] like Figure 5 As shown, the effective length of the toothless portion 26 on the first arc-shaped rack 20 is greater than the effective length of the first toothed portion 21. This results in the following motion trajectory for the air guide plate 10 as it extends to the intermediate position. During the process of the air guide plate 10 extending from the closed state to the intermediate position, two motion processes occur: When the air guide plate 10 is in the closed state, the gear 40 is located at the effective starting end of the first toothed portion 21 and the second toothed portion 31. The gear 40 simultaneously meshes with both the first toothed portion 21 and the second toothed portion 31, driving the air guide plate 10 to extend to the inclined position; when the air guide plate 10 is in the inclined position, the gear 40 meshes with the end of the first toothed portion 21, approximately meshing with the toothless portion 26, while simultaneously maintaining mesh with the second toothed portion 31, driving only the second arc-shaped rack 30 to move. During the process where the gear 40 only meshes with the second toothed portion 31, the first arc-shaped rack 20, under its own gravity, still moves synchronously with the second arc-shaped rack 30.

[0074] During the retraction of the air guide plate 10 from the air intake position, the gear 40 first drives the second arc-shaped rack 30 to move. Then, through the aforementioned limiting structure, the second arc-shaped rack 30 drives the first arc-shaped rack 20 to move. In this process, by extending the length of the toothless portion 26, the gear 40 is prevented from engaging with the first toothed portion 21 prematurely. This allows the first arc-shaped rack 20 sufficient space to adjust the position of its teeth, ensuring that its teeth correspond to the teeth of the second arc-shaped rack 30 in a preset position, preventing misalignment.

[0075] Optionally, one end of the first arc-shaped rack 20 is provided with a first connecting hole 22, which is used to hinge with the air guide plate 10.

[0076] Optionally, one end of the air guide plate 10 is provided with a first mounting base 11, and the first mounting base 11 is provided with a mounting hole 111. The mounting hole 111 and the first connecting hole 22 are hinged together by a connector.

[0077] Optionally, one end of the second arc-shaped rack 30 is provided with a bent section 32, and a second connecting shaft 33 is arranged at the free end of the bent section 32, and the second connecting shaft 33 is used for sliding connection with the air deflector 10.

[0078] Optionally, the air deflector 10 is further provided with a second mounting seat 12, and the first mounting seat 11 and the second mounting seat 12 are arranged side by side, and the second mounting seat 12 is provided with a sliding channel 121, and the second connecting shaft 33 is slidingly arranged in the sliding channel 121.

[0079] Optionally, the sliding channel 121 is in a straight line type, and the width of the sliding channel 121 is equal to the outer diameter of the second connecting shaft 33. In this way, when the air deflector 10 rotates from the middle position to the horizontal state, the second connecting shaft 33 can slide in the sliding channel 121, so that the air deflector 10 rotates around the first connecting hole 22 as the fulcrum.

[0080] When the air deflector 10 is in the closed state, the second connecting shaft 33 is located at the starting end of the sliding channel 121. In the process that the air deflector 10 extends from the closed state to the middle position, the second connecting shaft 33 is always located at the starting end of the sliding channel 121, as shown in FIG. 4B. Figure 7 When the air deflector 10 rotates from the middle position to the horizontal state, the second connecting shaft 33 is located at the end of the sliding channel 121, as shown in FIG. 4C. Wherein, the starting end of the sliding channel 121 is the end of the sliding channel 121 close to the upper end of the air deflector 10, and the end of the sliding channel 121 is the end of the sliding channel 121 close to the middle of the air deflector 10. Figure 8

[0081] The arrangement of the bent section 32 on the second arc-shaped rack 30 can cooperate with the first arc-shaped rack 20 to make the air deflector 10 rotate from the middle position to the horizontal state. In the process that the air deflector 10 moves from the middle position to the horizontal state, the gear 40 is only in transmission connection with the second arc-shaped rack 30, and the first arc-shaped rack 20 stops moving. The second arc-shaped rack 30 is subjected to a downward movement force, and the force is transmitted to the bent section 32. The extension direction of the bent section 32 is opposite to the bending direction of the second arc-shaped rack 30, so that the second connecting shaft 33 at the free end of the bent section 32 is subjected to a downward and rearward movement force, and the second connecting shaft 33 moves from the starting end of the sliding channel 121 to the end of the sliding channel 121. The air deflector 10 is subjected to the above-mentioned force and moves from the middle position to the horizontal state.

[0082] Optionally, the length L1 of the limiting groove 25 is greater than the length L2 of the sliding channel 121.

[0083] ​When the air deflector 10 rotates from the intermediate position to the air guiding position, i.e., the horizontal state, the limiting column 36 slides from the upper end of the limiting groove 25 to the lower end of the limiting groove 25, the second connecting shaft 33 slides from the starting end of the sliding groove 121 to the ending end of the sliding groove 121, and the length L1 of the limiting groove 25 and the length L2 of the sliding groove 121 have a preset correlation. For example, when the length L1 of the limiting groove 25 is greater than the length L2 of the sliding groove 121, the air deflector 10 can rotate from the intermediate position to the horizontal position, thereby more accurately controlling the rotation angle of the air deflector 10.

[0084] Optionally, when the air deflector 10 is in the closed state, the angle between the air deflector 10 and the horizontal direction is ω0, and when the air deflector 10 is in the intermediate position, the angle between the air deflector 10 and the horizontal direction is ω1, wherein ω0>ω1.

[0085] As shown in Figure 9 , Figure 9 the solid line in Figure 9 is a state diagram of the rack set when the air deflector 10 is in the closed state, and the dashed line is a state diagram of the rack set when the air deflector 10 is in the intermediate position. During the process that the air deflector 10 extends from the closed state to the intermediate position, not only the position of the air deflector 10 changes, but also the angle between the air deflector 10 and the horizontal direction becomes smaller. That is, the air deflector 10 also rotates in the process of extension, so that the air deflector 10 rotates to the air guiding horizontal state as soon as possible through the smallest stroke.

[0086] Optionally, when the air deflector 10 moves from the closed state to the intermediate position, the first arc-shaped rack 20 and the second arc-shaped rack 30 rotate by an angle ω4, wherein ω4=ω0-ω1.

[0087] During the process that the air deflector 10 moves from the closed state to the intermediate position, the first arc-shaped rack 20 and the second arc-shaped rack 30 move synchronously, so that the rotation angles of the first arc-shaped rack 20 and the second arc-shaped rack 30 are both ω4. ω4 can be obtained by experiments or measurements of ω0 and ω1, and then the arc length corresponding to ω4 can be determined, i.e., the length of the tooth part of the first arc-shaped rack 20 and the second arc-shaped rack 30 in the above process can be obtained. According to the above process, the movement control of the first arc-shaped rack 20 and the second arc-shaped rack 30 on the air deflector 10 is more accurate, and the air deflector 10 can be opened to the air guiding position.

[0088] Optionally, when the air deflector 10 is in the intermediate position, the angle between the air deflector 10 and the horizontal direction is ω1, and the angle between the bending section 32 and the air deflector 10 is ω2, wherein ω1>ω2.

[0089] The state of the rack set when the air deflector 10 is in the intermediate position is shown in Figure 9The bending section 32 extends in a direction away from the second arc-shaped rack 30, and by defining the sizes of ω1 and ω2 at the intermediate position, the range of the angle between the bending section 32 and the horizontal direction can be obtained, so that the second arc-shaped rack 30 can drive the air deflector 10 to rotate from the intermediate position to the air guiding position according to the preset track, and the accuracy of the control of the movement track of the air deflector 10 by the second arc-shaped rack 30 is improved.

[0090] Optionally, when the air deflector 10 rotates from the intermediate position to the air guiding position, the angle of rotation of the second arc-shaped rack 30 relative to the first arc-shaped rack 20 is ω3, and the relationship between ω3, ω2 and ω1 satisfies: ω3 = ω1- ω2.

[0091] The angle of rotation ω1 of the air deflector 10 from the intermediate position to the air guiding position is equal to the sum of ω2 and ω3. The ω1 can be preset by experiment, and then the relationship between ω2 and ω3 can be obtained, so that the rotation angle of the air deflector 10 in the above process can be accurately controlled in the actual operation of the air deflector 10.

[0092] It can be understood that the arc length corresponding to ω3 is the length L1 of the limiting groove 25. By adjusting ω2, the length of the limiting groove 25 can be adjusted, and then the length of the air deflector upper slide 121 can be adjusted. In this way, the rack set can drive the air deflector 10 to rotate to the air guiding position according to the preset track.

[0093] In the embodiments of the present disclosure, the related angle parameters in the process of the air deflector 10 extending to the intermediate position and rotating from the intermediate position to the air guiding position are limited, so that the rack set can accurately drive the air deflector 10 to extend and rotate to the horizontal air guiding position, and the accuracy of the control of the movement stroke of the air deflector 10 by the rack set is improved.

[0094] Optionally, the above-mentioned rack set is arranged in the shell, the shell is fixed to the side of the air conditioner, and the first arc-shaped rack 20 and the second arc-shaped rack 30 are slidingly arranged in the shell. The side of the first arc-shaped rack 20 is provided with a first sliding block 24, the side of the second arc-shaped rack 30 is provided with a second sliding block 35, and the two sides of the shell are provided with sliding grooves, and the first sliding block 24 and the second sliding block 35 are slidingly arranged in the sliding grooves, respectively.

[0095] By arranging the sliding grooves in the shell, the movement direction of the first arc-shaped rack 20 and the second arc-shaped rack 30 under the transmission of the gear 40 is further limited, so that the first arc-shaped rack 20 and the second arc-shaped rack 30 can drive the air deflector 10 to move to the intermediate position according to the preset path, and then the second arc-shaped rack 30 slides under the joint limitation of the sliding grooves of the shell and the sliding cavity 23 of the first arc-shaped rack 20, and drives the air deflector 10 to rotate to the horizontal state.
