[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] like Figures 1 to 9 The air outlet switching mechanism of this embodiment includes: a baffle component 1, which is movably arranged on the air duct main body 6 of the air duct structure to block or avoid the auxiliary air outlet 61 of the air duct structure; a door panel component 2, which is installed on the inner side of the baffle component 1 to move under the drive of the baffle component 1; wherein the door panel component 2 is movably arranged relative to the baffle component 1, so that when the baffle component 1 is in a position for blocking the auxiliary air outlet 61, the inner wall surface of the door panel component 2 and the inner wall surface of the air duct main body 6 are smoothly transitioned. With the above arrangement, when the air duct structure needs to enter the air, the baffle component 1 drives the door panel component 2 to move to a position to avoid the auxiliary air outlet 61, so that the airflow in the air duct structure can smoothly pass through the auxiliary air outlet 61, so that the auxiliary air outlet 61 enhances the air intake capacity of the air duct structure. When the auxiliary air vent 61 of the air duct structure needs to block the air flow, the baffle component 1 drives the door panel component 2 to move to a position that blocks the auxiliary air vent 61. At this time, the door panel component 2 moves relative to the baffle component 1, so that the door panel component 2 blocks the auxiliary air vent 61 at an optimal position to achieve the best blocking effect. When the air duct structure does not need the auxiliary air vent 61 for ventilation, the wind blocking performance of the auxiliary air vent 61 can be guaranteed. In this way, the space around the auxiliary air vent 61 has a ventilation function, the utilization rate of the air flow is increased, and the problem of poor space utilization inside the air duct of the air conditioner in the prior art is solved.

[0043] In the tuyere switching mechanism of this embodiment, Figure 7 When the baffle component 1 is in a position for shielding the auxiliary air outlet 61 , the inner wall surface of the door panel component 2 is flush with the inner wall surface of the air duct main body 6 .

[0044] In order to achieve a better wind blocking effect, in the air outlet switching mechanism of this embodiment, when the baffle component 1 is in a position for shielding the auxiliary air outlet 61, the inner wall surface of the door panel component 2 is flush with the inner wall surface of the air duct body 6. In this way, the gap between the inner wall surface of the door panel component 2 and the inner wall surface of the air duct body 6 can be reduced, thereby improving the sealing performance of the structure.

[0045] In order to achieve better wind protection effect, Figure 1 In the air outlet switching mechanism of this embodiment, the air outlet switching mechanism further includes: an elastic component 3, which is arranged between the baffle component 1 and the door panel component 2, so that the door panel component 2 moves relative to the baffle component 1 under the action of the elastic component 3. In this way, when the door panel component 2 reaches the shielding position, the inner wall surface of the door panel component 2 can be pushed by the elastic component 3 to be flush with the inner wall surface of the air duct main body 6.

[0046] In order to achieve the purpose of the door panel component 2 moving relative to the baffle component 1 under the action of the elastic component 3, in the air outlet switching mechanism of this embodiment, as shown in FIG. Figure 7The baffle member 1 and / or the door panel member 2 is provided with a latch structure 11, and the elastic member 3 is mounted on the latch structure 11. In this way, the position of the elastic member 3 is fixed, thereby completing the action of pushing the door panel member 2 and improving the stability of the structure.

[0047] like Figure 1 In the air outlet switching mechanism of this embodiment, the latch structure 11 includes a latch column 111 and a limiting ring 112 arranged around the latch column 111, and the elastic component 3 is sleeved on the latch column 111 and located on the inner side of the limiting ring 112.

[0048] In the air outlet switching mechanism of this embodiment, the latch structure 11 includes a latch column 111 and a limiting ring 112 arranged around the latch column 111. The latch column 111 is used to control the extension direction of the elastic component 3. The elastic component 3 is sleeved on the latch column 111 and located inside the limiting ring 112, thereby fixing the position of the elastic component 3. In this way, the air outlet switching mechanism can achieve a better wind blocking effect.

[0049] In the tuyere switching mechanism of this embodiment, Figure 1 The baffle component 1 and the door panel component 2 are connected by a rotating shaft structure 21, so that the door panel component 2 rotates around a predetermined rotation axis; the elastic component 3 is arranged on a side of the door panel component 2 that is parallel to the center line of the predetermined rotation axis and is far away from the rotating shaft structure 21. In this way, one end of the baffle component 1 and the door panel component 2 can be rotatably fixed, so that the other end of the door panel component 2 can move freely in a stable state.

[0050] like Figure 1 In the air outlet switching mechanism of this embodiment, the rotating shaft structure 21 includes a rotating shaft hole 211 and a rotating shaft 212 inserted in the rotating shaft hole 211. The rotating shaft hole 211 is arranged on the door panel component 2 or the baffle component 1, and the rotating shaft 212 is arranged on the baffle component 1 or the door panel component 2. In this way, the baffle component 1 and the door panel component 2 are rotatably connected.

[0051] In the tuyere switching mechanism of this embodiment, Figure 1 The door panel component 2 is provided with a lap structure 22, and the rotating shaft structure 21 and the lap structure 22 are respectively provided at opposite ends of the door panel component 2; the baffle component 1 is provided with a mounting groove 12, and at least part of the lap structure 22 is clamped in the mounting groove 12. In this way, when the air outlet switching structure is in the avoidance state, the door panel component 2 is clamped in the mounting groove 12, so that the door panel component 2 will not shake, thereby avoiding the door panel component 2 from colliding with the air duct structure, thereby scratching the air duct structure or generating noise.

[0052] like Figure 1In the air outlet switching mechanism of this embodiment, the overlapping structure 22 is a step structure spliced ​​by a first strip plate 221 and a second strip plate 222. The first strip plate 221 is connected to the main body of the door panel component 2. The baffle component 1 has a clamping portion 13, which is arranged at the slot of the mounting groove 12 and is opposite to the bottom of the mounting groove 12. The second strip plate 222 is clamped on the inner side of the clamping portion 13.

[0053] In the tuyere switching structure of this embodiment, the overlapping structure 22 is composed of a first strip plate 221 and a second strip plate 222, and the first strip plate 221 and the second strip plate 222 form a step structure. In this arrangement, the second strip plate 222 is used to connect with the mounting groove 12, thereby fixing the door panel component 2. The first strip plate 221 is used to keep the second strip plate 222 away from the door panel component 2, so that a space for placing the elastic component 3 is formed between the door panel component 2 and the baffle component 1.

[0054] In the tuyere switching mechanism of this embodiment, Figure 1 A first guide slope 611 is provided at the auxiliary air outlet 61, and a second guide slope 23 matching the first guide slope 611 is provided on the door panel component 2, so that when the baffle component 1 moves toward the direction for avoiding the auxiliary air outlet 61, the door panel component 2 moves toward the direction close to the baffle component 1 under the cooperation between the first guide slope 611 and the second guide slope 23. In this way, when the air outlet switching structure switches between the avoiding state and the shielding state, the switching process is smoother.

[0055] In order to provide power for the movement of the air outlet switching mechanism, in the air outlet switching mechanism of this embodiment, the air outlet switching mechanism also includes: a driving component; a driven component 5, the driving component is drivingly connected to the driven component 5, and the driven component 5 is connected to the baffle component 1, so that the driving component drives the baffle component 1 to move through the driven component 5.

[0056] Specifically, in the tuyere switching mechanism of this embodiment, Figure 1 The driving component is a motor, which is fixed relative to the air duct body 6; the driven component 5 includes a transmission gear 51 arranged on the output shaft of the motor and a transmission rack 52 arranged on the baffle component 1, and the transmission gear 51 is meshed with the transmission rack 52. In this way, the transmission gear 51 is driven to rotate by the rotation of the motor, and the transmission gear 51 drives the transmission rack 52 to move, so that the baffle component 1 drives the door panel component 2 to move.

[0057] like Figure 1 In the tuyere switching mechanism of this embodiment, the driven assembly 5 further includes a connecting plate 53, and the transmission rack 52 is connected to the baffle member 1 through the connecting plate 53. The connecting plate 53 provides a position for the installation of the transmission rack 52.

[0058] In order to achieve the effect of relative movement between the baffle component 1 and the air duct body 6, in the air outlet switching mechanism of this embodiment, as shown in FIG. Figure 7 The air duct body 6 is provided with a guide rail 62, and the baffle component 1 is provided with a rolling member 14, and the rolling member 14 can rollably contact the guide rail 62. With the above arrangement, the friction between the baffle component 1 and the air duct body 6 can be reduced, thereby reducing the noise when the structure is working and improving the comfort of users.

[0059] like Figure 1 In the tuyere switching mechanism of this embodiment, a snap-on structure 15 is provided on the baffle component 1 , and the rolling element 14 is rotatably sleeved on the snap-on structure 15 .

[0060] In order to realize the assembly of the snap-on structure 15, in the air outlet switching mechanism of this embodiment, as shown in FIG. Figure 7 The snap-fastener structure 15 includes a first snap-fastener 151 and a second snap-fastener 152 that are spaced apart.

[0061] like Figure 1 In the tuyere switching mechanism of this embodiment, a group of rolling members 14 are provided at opposite ends of the baffle member 1, and the two groups of rolling members 14 are matched with the two guide rails 62 in a one-to-one correspondence; a group of rolling members 14 includes a plurality of rolling members 14, and the plurality of rolling members 14 are arranged at intervals along the moving direction of the baffle member 1. With the above arrangement, when the tuyere switching mechanism avoids or blocks the auxiliary tuyere 61, the stability of the structure is ensured.

[0062] In the air duct structure of this embodiment, Figures 5 to 7 The air duct main body 6 is provided with an air inlet 63, an auxiliary air outlet 61 and an air outlet, and the air duct structure also includes: an air outlet switching mechanism 10, the air outlet switching mechanism 10 is the above-mentioned air outlet switching mechanism, and the baffle component of the air outlet switching mechanism 10 is used to open or close the auxiliary air outlet 61.

[0063] In the air duct structure of this embodiment, the air duct structure includes an air duct main body 6, on which an air inlet 63, an auxiliary air outlet 61 and an air outlet are arranged. The air duct structure also includes: an air outlet switching mechanism 10, at least part of which is movably arranged to open or close the auxiliary air outlet 61.

[0064] In the air conditioner of this embodiment, the air conditioner includes an air duct structure, and the air duct structure is the above-mentioned air duct structure.

[0065] The air conditioner of this embodiment is described below:

[0066] For cabinets with reversible air outlet, when the air is discharged in the cooling mode, the volute tongue will rotate to the lower side, resulting in a "dead end" in the lower part of the air duct, wasting some space and easily causing noise. The air conditioner of this embodiment has a movable air outlet on the inner wall of the air duct, which can effectively increase the air intake area inside the air conditioner, make the air intake more uniform, and reduce the noise caused by internal turbulence. The increase in the air intake volume will also increase the air outlet volume, improve the performance of the whole machine, and optimize the user experience.

[0067] When the air outlet switching mechanism 10 of this embodiment is working, when the air conditioner takes in air, the door panel component 2 slides downward under the drive of the baffle component 1, and an air outlet (auxiliary air outlet 61) is added to the side wall of the air duct, so that the air conditioner effectively utilizes the wind inside the air duct, expands the air intake area, avoids the air intake area being too narrow, and forms a virtuous cycle as a whole. This ensures that the air intake of the air conditioner is smooth, avoids the air duct curve from separating from the air flow to generate vortices, reduces the intensity of the vortices, and reduces the noise of the vortices.

[0068] like Figure 7 When the air outlet switching mechanism 10 blocks the auxiliary air outlet 61, the door panel component 2 is kept in an open state due to the stress of the spring (elastic component 3) on the baffle component 1. A certain travel space is reserved inside the air outlet switching mechanism 10 for closing the door panel component 2. Inclined surfaces (first guide inclined surface 611 and second guide inclined surface 23) are respectively provided on the mating surfaces of the door panel component 2 and the air duct to facilitate the up and down movement of the door panel component 2. Sponge or rubber should be provided on the mating surfaces of the air duct and the door panel component 2 to ensure its airtightness.

[0069] like Figure 5 When the air outlet switching mechanism 10 avoids the auxiliary air outlet 61, the motor drives the transmission gear 51 to rotate, and the transmission gear 51 is tightly meshed with the transmission rack 52, so that the air outlet switching mechanism 10 moves up and down. When the air outlet switching mechanism 10 starts to move, the door panel component 2 is also subjected to a downward driving force, and the force is transmitted to the inclined surface on the air duct. The door panel component 2 rotates with the shaft structure 21 as the rotation axis, and the front end of the door panel component 2 moves up to the inside of the baffle component 1. At the same time, the spring is squeezed and stressed, so that the door panel component 2 is located on the surface of the air duct as a whole, ensuring that the air outlet switching mechanism 10 can run along the guide rail on the surface of the air duct as a whole.

[0070] When the air conditioner needs to blow air downward, the integrity of the inner wall of the air duct needs to be ensured, and the air outlet switching mechanism 10 needs to be closed. At this time, the motor reverses and drives the air outlet switching mechanism 10 to move upward. When the baffle component moves to the limit position, the spring releases the stress and pushes the door panel component 2 back to the original position. When the door panel component 2 is closed, it can connect with the inner wall of the air duct, ensuring that the wind can stick to the air duct to reduce the vortex noise formed by the steps.

[0071] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0072] The air outlet switching mechanism of this embodiment includes: a baffle component 1, which is movably arranged on the air duct main body 6 of the air duct structure to block or avoid the auxiliary air outlet 61 of the air duct structure; a door panel component 2, which is installed on the inner side of the baffle component 1 to move under the drive of the baffle component 1; wherein the door panel component 2 is movably arranged relative to the baffle component 1, so that when the baffle component 1 is in a position for blocking the auxiliary air outlet 61, the inner wall surface of the door panel component 2 and the inner wall surface of the air duct main body 6 are smoothly transitioned. With the above arrangement, when the air duct structure needs to take in air, the baffle component 1 drives the door panel component 2 to move to a position to avoid the auxiliary air outlet 61, so that the airflow in the air duct structure can smoothly pass through the auxiliary air outlet 61, so that the auxiliary air outlet 61 enhances the air intake capacity of the air duct structure. When the auxiliary air vent 61 of the air duct structure needs to block the air flow, the baffle component 1 drives the door panel component 2 to move to a position that blocks the auxiliary air vent 61. At this time, the door panel component 2 moves relative to the baffle component 1, so that the door panel component 2 blocks the auxiliary air vent 61 at an optimal position to achieve the best blocking effect. When the air duct structure does not need the auxiliary air vent 61 for ventilation, the wind blocking performance of the auxiliary air vent 61 can be guaranteed. In this way, the space around the auxiliary air vent 61 has a ventilation function, the utilization rate of the air flow is increased, and the problem of poor space utilization inside the air duct of the air conditioner in the prior art is solved.

For those skilled in the art, the present invention may have various modifications and variations.
