[0044] 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.

[0045] like Figures 1 to 15As shown, the wind direction switching mechanism of this embodiment is arranged in the housing 6 of the air conditioner to block or avoid the air duct between the vent 11 of the air conditioner and the air inlet of the fan 2 of the air conditioner (i.e., the air inlet channel 12 in this embodiment), and the wind direction switching mechanism includes: a baffle 31, one end of which is movably arranged so that the baffle 31 is in a blocking state for blocking the air inlet channel 12 or a avoiding state for avoiding the air inlet channel 12; a track groove, the track groove is used to accommodate the baffle 31, and the track groove extends along the circumference of the side wall of the air duct. With the above arrangement, the driving component 32 of the wind direction switching mechanism drives the baffle 31 to move the baffle 31 in the air inlet channel 12 to block or avoid the air inlet channel 12. When the baffle 31 is in the blocking state, the baffle 31 moves toward the side wall of the air inlet channel 12 and seals with the track groove, thereby blocking the air inlet channel 12 to prevent the air flow in the air inlet channel 12 from passing through the baffle 31. The wind direction switching mechanism in the present application, when the baffle is in the blocking state, this movable baffle 31 can ensure sufficient sealing with the side wall of the air inlet channel 12, without reserving a movable gap, and the baffle 31 is in sealing contact with the inner wall surface of the air duct along the circumference of the air duct through the track groove. Therefore, it can effectively prevent the airflow from leaking from the baffle 31. When the baffle 31 is in the avoidance state, the airflow can smoothly pass through the baffle 31 in the air inlet channel 12. In this way, when the wind direction switching structure blocks the air duct, the sealing between the wind direction switching structure and the surrounding air duct side walls is ensured. By controlling the baffle 31 to block or avoid the air inlet channel 12, the airflow in the air inlet channel 12 can be effectively guided, so that the airflow flows according to the needs of the air conditioner, thereby increasing the airflow utilization efficiency of the air conditioner and solving the problem of air leakage in the air conditioner in the prior art.

[0046] As an embodiment of a wind direction switching mechanism, Figures 1 to 4 As shown, the wind direction switching mechanism further includes: a driving component 32, the driving component 32 is drivingly connected to the baffle 31 to drive the baffle 31 to switch between the shielding state and the avoidance state, a transmission gear 33, the driving component 32 is a motor, the transmission gear 33 is installed on the output shaft of the motor, and the baffle 31 is provided with a rack portion 311 meshing with the transmission gear 33. In this embodiment, the movement of the baffle 31 is achieved by the cooperation of the transmission gear 33 and the rack portion 311, and this structure is simple and easy to operate.

[0047] In the wind direction switching mechanism of this embodiment, Figures 1 to 4 As shown, the baffle 31 is provided with a mounting groove 312, which extends along the moving direction of the baffle 31; the driving component 32 is arranged in the mounting groove 312, and the rack portion 311 is arranged on the inner wall of the mounting groove 312. With the above arrangement, the structure of the wind direction switching mechanism is more solid and the internal space of the air conditioner is saved.

[0048] It should be noted that the moving direction of the baffle 31 is as follows: Figure 2 The wind direction switching mechanism is in the avoidance state. When the baffle 31 moves in the direction shown in the figure, the wind direction switching mechanism is in the shielding state.

[0049] like Figures 1 to 4 As shown, in the wind direction switching mechanism of this embodiment, the baffle 31 includes a baffle body 313 and a mounting portion 314 disposed on the baffle body 313 . The mounting portion 314 is a U-shaped structure, and the inner wall surface of the U-shaped structure forms a mounting groove 312 .

[0050] Preferably, the baffle body 313 and the mounting portion 314 of this embodiment are an integrated structure, so that the structure of the baffle 31 is simpler, thereby reducing the production cost.

[0051] In the wind direction switching mechanism of this embodiment, Figures 1 to 4 As shown, a slide rail 41 is provided on the air duct structure 4 of the air conditioner, and a slide groove 315 matching with the slide rail 41 is provided on the baffle 31. The slide groove 315 is parallel to the installation groove 312, and the slide groove 315 and the installation groove 312 are respectively located on opposite sides of the baffle 31.

[0052] In order to make the movement of the baffle 31 smoother, in this embodiment, a slide rail 41 is provided on the air duct structure 4 of the air conditioner, and a slide groove 315 matching the slide rail 41 is provided on the baffle 31, and the slide groove 315 is parallel to the mounting groove 312. In this way, the baffle 31 moves by sliding, which can reduce the friction of the movement of the baffle 31. The slide groove 315 and the mounting groove 312 are respectively arranged on the opposite sides of the baffle 31, so that the movement of the baffle 31 is smoother, so that the air duct can be better shielded and avoided, and the airflow in the air conditioner will not leak out.

[0053] In order to achieve a smoother movement of the baffle 31, as Figures 1 to 4 As shown, in the wind direction switching mechanism of this embodiment, the baffle 31 includes a baffle body 313 and a sliding portion 317 arranged on the baffle body 313. The sliding portion 317 is a U-shaped structure, and the inner wall surface of the U-shaped structure forms a sliding groove 315.

[0054] As another embodiment of the wind direction switching mechanism, in the wind direction switching mechanism of this embodiment, Figures 1 to 4 As shown, the wind direction switching mechanism also includes: a track frame 34, the track frame 34 has a track groove for installing the baffle 31; a reel 35, the reel 35 is rotatably installed on the track frame 34, the driving component 32 is a motor, the output shaft of the motor is connected to the reel 35, and the baffle 31 is a flexible plate, so that the baffle 31 is wound on the reel 35 when the motor drives the reel 35 to rotate.

[0055] In this embodiment, the wind direction switch includes a track frame 34 and a reel 35, the driving component 32 is a motor, and the baffle 31 is a flexible board. The baffle 31 made of the flexible board can achieve repeated curling and extension. In this way, the output shaft of the motor is connected to the reel 35 to drive the reel 35 to rotate. One end of the baffle 31 is connected to the reel 35. When the reel rotates, the baffle 31 can be expanded or retracted under the action of the reel 35. In this way, the effect of shielding or avoiding the air inlet channel 12 can be achieved. With the above arrangement, the control of the baffle 31 is more flexible, making the structure of the wind direction switch more concise.

[0056] In order to achieve the effect that the baffle 31 can be expanded or retracted under the action of the reel 35, as shown in FIG. Figure 7 , Figure 8 As shown, in the wind direction switching mechanism of this embodiment, a first transmission tooth is arranged on the outer peripheral surface of the reel 35, and a second transmission tooth 316 is arranged on the two plate surfaces of the baffle 31, so that the baffle 31 is wound on the reel 35 under the meshing action of the first transmission tooth and the second transmission tooth 316 and the meshing action of the second transmission tooth 316 on the two plate surfaces of the baffle 31.

[0057] In the wind direction switching mechanism of this embodiment, Figures 1 to 4 As shown, the track frame 34 includes: a first plate body 341 and a second plate body 342 arranged opposite to each other; a first side plate 343 and a second side plate 344 arranged opposite to each other, the first side plate 343 and the second side plate 344 are both arranged between the first plate body 341 and the second plate body 342, and the first plate body 341, the second plate body 342, the first side plate 343 and the second side plate 344 form a track groove; wherein the first plate body 341 and the second plate body 342 are both provided with airflow openings 345 for airflow to pass through.

[0058] In the wind direction switching mechanism of this embodiment, the track frame 34 is composed of a first plate body 341, a second plate body 342, a first side plate 343 and a second side plate 344. When the wind direction switching mechanism blocks the air inlet channel 12, the baffle 31 blocks the air flow opening 345. When the wind direction switching mechanism is in the avoidance state, the baffle 31 is rolled up, and the air flow in the air inlet channel 12 flows through the wind direction switching mechanism through the air flow opening 345.

[0059] like Fig. 9 As shown, the air conditioner of this embodiment includes a casing 6 and a duct structure 4 arranged in the casing 6. The air conditioner also includes: a wind direction switching mechanism 3, which is the above-mentioned wind direction switching mechanism, and the wind direction switching mechanism 3 is arranged between the casing 6 and the duct structure 4.

[0060] In the air conditioner of this embodiment, an upper air inlet and a lower air inlet are provided on the casing 6, an upper air inlet channel 121 is provided between the upper air inlet and the air inlet of the fan 2 of the air duct structure 4, and a lower air inlet channel 122 is provided between the lower air inlet and the air inlet of the fan 2 of the air duct structure 4; a wind direction switching mechanism 3 is provided in both the upper air inlet channel 121 and the lower air inlet channel 122.

[0061] In the air conditioner of this embodiment, the fan 2 has two air inlets 21, and there are two upper air inlet channels 121 and two lower air inlet channels 122. The two upper air inlet channels 121 are arranged in a one-to-one correspondence with the two air inlets 21 of the fan 2, and the two lower air inlet channels 122 are arranged in a one-to-one correspondence with the two air inlets of the fan 2.

[0062] The air conditioner of this embodiment is described below:

[0063] In the air conditioner of the present embodiment, when the air conditioner starts the heating mode, the upper air vent takes in air, the lower air vent discharges hot air, the upper wind direction switching mechanism 3 is opened (a wind direction switching mechanism 3 with a baffle 31 is provided on each of the left and right sides), and the lower wind direction switching mechanism 3 is closed (a wind direction switching mechanism 3 with a baffle 31 is provided on each of the left and right sides), and when the cooling mode is started, the lower air vent takes in air, the upper air vent discharges cold air, the lower left and right wind direction switching mechanisms 3 are opened, and the upper left and right wind direction switching mechanisms 3 are closed, so as to realize a wind direction switching with different air inlet and different air outlet directions. By setting the wind direction switching mechanism 3, the effective sealing of the air inlet channel 12 can be realized, and the problem of air leakage caused by the inability of the baffle rotating mechanism in the prior art to effectively seal can be solved, thereby avoiding the problem of the air volume of the air conditioner becoming smaller and the cooling or heating effect becoming worse. Moreover, in the existing structure, due to the gap between the baffle and the air inlet panel and the decorative panel, it is easy to form a wind vortex in the gap area when the air enters, thereby causing rotation noise. The wind direction switching mechanism 3 of this embodiment can also solve the noise problem generated by the original structure during operation. In addition, the existing rotating mechanism is designed to be installed in the air inlet channel, which not only occupies the space of the air inlet channel, but also the motor (driving component 32) is exposed to the outside. When running in the cooling mode, it is easy to generate condensed water, causing water to enter the motor, which is easy to cause motor operation failure.

[0064] The air conditioner of this embodiment is provided with a wind direction switching mechanism 3, and the motor is installed in the motor slot on one side of the air duct. A rack portion 311 is provided at the right end of the baffle 31 to cooperate with the motor to realize the driving of the baffle 31, and a slide mechanism is provided on the other side to ensure that it can limit the left and right positions and start the support during operation, so as to ensure that the structure will not shake during operation. In addition, the motor is designed in the motor slot at the lower end of the air duct, which is easier to seal. In the cooling mode, it is not easy to generate condensed water and cause operation failure.

[0065] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0066] According to the technical solution of the present invention, a wind direction switching mechanism is arranged in the housing 6 of the air conditioner to block or avoid the air duct between the vent 11 of the air conditioner and the air inlet of the fan 2 of the air conditioner (i.e., the air inlet channel 12 in this embodiment), and the wind direction switching mechanism includes: a baffle 31, one end of which is movably arranged so that the baffle 31 is in a blocking state for blocking the air inlet channel 12 or a avoiding state for avoiding the air inlet channel 12; and a track groove, which is used to accommodate the baffle 31, and the track groove extends along the circumference of the side wall of the air duct. With the above arrangement, the driving component 32 of the wind direction switching mechanism drives the baffle 31 to move the baffle 31 in the air inlet channel 12 to block or avoid the air inlet channel 12. When the baffle 31 is in the blocking state, the baffle 31 moves toward the side wall of the air inlet channel 12 and seals with the track groove, thereby blocking the air inlet channel 12 to prevent the air flow in the air inlet channel 12 from passing through the baffle 31. The wind direction switching mechanism in the present application, when the baffle is in the blocking state, this movable baffle 31 can ensure sufficient sealing with the side wall of the air inlet channel 12, without reserving a movable gap, and the baffle 31 is in sealing contact with the inner wall surface of the air duct along the circumference of the air duct through the track groove. Therefore, it can effectively prevent the airflow from leaking from the baffle 31. When the baffle 31 is in the avoidance state, the airflow can smoothly pass through the baffle 31 in the air inlet channel 12. In this way, when the wind direction switching structure blocks the air duct, the sealing between the wind direction switching structure and the surrounding air duct side walls is ensured. By controlling the baffle 31 to block or avoid the air inlet channel 12, the airflow in the air inlet channel 12 can be effectively guided, so that the airflow flows according to the needs of the air conditioner, thereby increasing the airflow utilization efficiency of the air conditioner and solving the problem of air leakage in the air conditioner in the prior art.

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