[0005] To solve the above problems, the utility model provides an indoor unit, which is provided with an air outlet; the indoor unit comprises: a first air deflector and a second air deflector arranged at the air outlet, the first air deflector is arranged on the side of the second air deflector away from the evaporator of the indoor unit; the first air deflector is movably connected with the indoor unit to open or close the air outlet; the second air deflector is movably connected with the indoor unit to open or close the air outlet; and multiple micro holes are arranged on the second air deflector.

[0006] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: in combination with the running cooling condition of the indoor unit, the air outlet is closed by adjusting the second air deflector, and air is discharged only through the multiple micro holes arranged thereon; the dispersion effect of the air flow through the multiple micro holes effectively realizes the avoidance of the situation of cold wind direct blowing; in combination with the arrangement of the first air deflector, the air outlet is closed by adjusting the first air deflector after the indoor unit stops running, thereby avoiding the situation that insects and other organisms in the indoor environment or dust can enter the indoor unit through the micro holes, thereby reducing the service life of the indoor unit. In addition, during the opening stage of the indoor unit, rapid cooling of the indoor environment is required, so the air outlet can be opened by adjusting the first air deflector and the second air deflector at the same time, the guiding effect of the air flow through the first air deflector is utilized to accelerate the diffusion range of the air flow in the indoor environment, thereby improving the cooling efficiency of the indoor unit.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: specifically, since the first air guide plate and the second air guide plate are respectively rotatably connected to the lower end, it can be achieved that when the second air guide plate abuts against the surface of the first air guide plate and the two are adjusted to open the air outlet at the maximum angle, the cold air is effectively delivered to the farthest point of the indoor environment, which ensures the heat exchange efficiency between the indoor unit and the indoor environment at this time.

[0011] In one embodiment of the present invention, the two opposite ends of the indoor unit forming the air outlet are defined as the upper end and the lower end; the first air guide plate is rotatably connected to the lower end; and the second air guide plate is rotatably connected to the rotating shaft provided between the upper end and the lower end.

[0012] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by adjusting the opening of the first air guide plate and the second air guide plate relative to the air outlet, the maximum air outlet and the windless mode air outlet derived from the air outlet are effectively achieved when the indoor unit is in the cooling mode.

[0013] In one embodiment of the present invention, the first air guide plate is connected to the position of the indoor unit corresponding to the air outlet by a first drive motor; and / or the second air guide plate is connected to the position of the indoor unit corresponding to the air outlet by a second drive motor.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the efficiency of regulating the rotation of the first air guide plate and / or the second air guide plate is improved.

[0015] In one example of the present invention, during the rotation of the first air guide plate and the second air guide plate relative to the air outlet, the angle formed between the first air guide plate and the second air guide plate is a; wherein, when a is 0°, the first air guide plate and the second air guide plate simultaneously close or open the air outlet; when a>0°, at most one of the first air guide plate and the second air guide plate closes the air outlet.

[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by flexibly adjusting the rotation angle of the first air guide plate and the second air guide plate at the air outlet, the thermal interaction efficiency between the indoor unit and the indoor environment is ensured.

[0017] In one example of the present invention, when the second air guide plate is rotatably connected to the rotating shaft provided between the upper end and the lower end, the rotation angle of the second air guide plate is b1, 0°≤b1≤180°; and / or when the second air guide plate is rotatably connected to the lower end, the rotation angle of the second air guide plate is b2, 0°≤b2≤45°.

The multiple micro-holes disperse the airflow, effectively preventing the cold wind from blowing directly on people. In combination with the setting of the first air guide plate, after the indoor unit stops running, it can be adjusted to close the air outlet, thereby preventing insects and other creatures in the indoor environment, or dust, from entering the indoor unit through the micro-holes, thereby reducing the service life of the indoor unit. In addition, when the indoor unit is turned on, if the indoor environment needs to be cooled quickly, the air outlet can be opened at the same time by adjusting the first air guide plate and the second air guide plate.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] See also Figure 1 , which is a structural diagram of an indoor unit 100 in a first relative state provided by an embodiment of the present utility model. Figure 2-Figure 6 Specifically, the indoor unit 100 is provided with an air outlet 103. The indoor unit 100 includes, for example, a first air guide plate 10 and a second air guide plate 20 arranged at the air outlet 103. The first air guide plate 10 is arranged on the side of the second air guide plate 20 away from the evaporator 104 of the indoor unit 100; the first air guide plate 10 is movably connected to the indoor unit 100 to open or close the air outlet 103; the second air guide plate 20 is movably connected to the indoor unit 100 to open or close the air outlet 103; and a plurality of micropores are provided on the second air guide plate 20.

[0038] In conjunction with the cooling operation of the indoor unit 100, the second air guide plate 20 is adjusted to close the air outlet 103, and air is discharged only through the multiple micropores provided thereon. The multiple micropores disperse the airflow, effectively preventing the cold air from blowing directly on people. In conjunction with the configuration of the first air guide plate 10, after the indoor unit 100 stops operating, it can be adjusted to close the air outlet 103, thereby preventing insects and other organisms, or dust, from entering the indoor unit 100 through the micropores, thereby reducing the service life of the indoor unit 100. In addition, when the indoor unit 100 is turned on, if the indoor environment needs to be cooled quickly, the air outlet 103 can be opened simultaneously by adjusting the first air guide plate 10 and the second air guide plate 20. The first air guide plate 10 guides the airflow, thereby accelerating the diffusion range of the airflow in the indoor environment, thereby improving the cooling efficiency of the indoor unit 100.

[0039] Preferably, the first air guide plate 10 and the second air guide plate 20 are transformed between multiple relative states relative to the air outlet 103;

[0040] When in a first relative state among the multiple relative states, the first air guide plate 10 closes the air outlet 103 , and the second air guide plate 20 closes the air outlet 103 ; or

[0041] When in a second relative state among the plurality of relative states, the first air guide plate 10 opens the air outlet 103 , and the second air guide plate 20 opens the air outlet 103 ; or

[0042] In the third relative state among the multiple relative states, the first air guide plate 10 opens the air outlet 103, and the second air guide plate 20 closes the air outlet 103. By flexibly adjusting the opening angles of the first air guide plate 10 and the second air guide plate 20 relative to the air outlet 103, the user's cooling needs in different scenarios are fully met.

[0043] Specifically, unlike the second air guide plate 20, the surface of the first air guide plate 10 is not provided with micropores. Therefore, the enclosed area of ​​the air outlet 103 can be adjusted by adjusting the rotation of the first air guide plate 10 at the air outlet 103. Combined with the structural characteristics of the second air guide plate 20, the second air guide plate 20 is used to achieve the effect of no wind. Furthermore, by combining the movement angles of the first air guide plate 10 and the second air guide plate 20 at the air outlet 103, different air conditioning air supply operation modes are formed. Furthermore, the deflection angle of the first air guide plate 10 affects the direction of the outlet airflow and the air volume per unit time, while the deflection angle of the second air guide plate 20 affects the momentum of the outlet airflow.

[0044] Combine Figure 1 and Figure 4 Furthermore, in the initial closed state, that is, in the first relative state, the air outlet 103 is blocked by the first air guide plate 10 and the second air guide plate 20 at the same time. Since the second air guide plate 20 is located on the inner side 102 of the air outlet 103 compared to the first air guide plate 10, the first air guide plate 10 is arranged on the outer side 101 of the air outlet 103, which effectively isolates the air outlet 103 from the outside and prevents mosquitoes and dust from entering the interior of the indoor unit 100.

[0045] Combine Figure 2 and Figure 5 When the indoor unit 100 is in cooling mode, that is, in the second relative state, the movement deflection angle of the first air guide plate 10 is adjusted to the maximum so that the enclosed area of ​​the air outlet 103 is maximized. At this time, the second air guide plate 20 is adjusted to deflect in line with the air outlet direction to achieve the best air conditioning cooling capacity.

[0046] Combine Figure 3 and Figure 6 Furthermore, in the windless mode, or the third relative position, the first air guide 10 reaches its maximum deflection angle, while the second air guide 20 returns to its initial closed position, closing the air outlet 103. The second air guide 20 then breaks down the outgoing airflow into "thread-like" micro-clusters through its multiple micro-holes, reducing the airflow momentum and achieving windless airflow.

[0047] Combine Figure 1-Figure 3 Preferably, in one embodiment, the two opposite ends of the indoor unit 100 forming the air outlet 103 are defined as an upper end 106 and a lower end 107; the first air guide plate 10 is rotatably connected to the lower end 107; and the second air guide plate 20 is rotatably connected to the lower end 107. Specifically, because the first air guide plate 10 and the second air guide plate 20 are respectively rotatably connected to the lower end 107, when the second air guide plate 20 abuts against the surface of the first air guide plate 10 and the two are adjusted to open the air outlet 103 at the maximum angle, the cold air is effectively delivered to the farthest point in the indoor environment, thereby ensuring the heat exchange efficiency between the indoor unit 100 and the indoor environment at this time.

[0048] Combine Figure 4-Figure 6 Different from the aforementioned example, in another example, the two opposing ends of the indoor unit 100 forming the air outlet 103 are defined as an upper end 106 and a lower end 107; the first air guide plate 10 is rotatably connected to the lower end 107; and the second air guide plate 20 is rotatably connected to a rotating shaft 105 disposed between the upper end 106 and the lower end 107. By adjusting the opening of the first air guide plate 10 and the second air guide plate 20 relative to the air outlet 103, the indoor unit 100 effectively achieves maximum air flow from the air outlet 103 in cooling mode and air flow in a windless mode.

[0049] Preferably, the first air deflector 10 is connected to the position of the indoor unit 100 corresponding to the air outlet 103 by a first drive motor; and / or the second air deflector 20 is connected to the position of the indoor unit 100 corresponding to the air outlet 103 by a second drive motor. This improves the efficiency of adjusting the rotation of the first air deflector 10 and / or the second air deflector 20.

[0050] Combine Figure 3 Preferably, during the rotation of the first and second air deflectors 10, 20 relative to the air outlet 103, the angle formed between the first and second air deflectors 10, 20 is a. When a is 0°, the first and second air deflectors 10, 20 simultaneously close or open the air outlet 103. When a is greater than 0°, at most one of the first and second air deflectors 10, 20 closes the air outlet 103. By flexibly adjusting the rotation angle of the first and second air deflectors 10, 20 at the air outlet 103, the efficiency of thermal interaction between the indoor unit 100 and the indoor environment is ensured.

[0051] Preferably, when the second air deflector 20 is rotatably connected to the rotating shaft 105 disposed between the upper end 106 and the lower end 107, the rotation angle of the second air deflector 20 is b1, 0°≤b1≤180°; and / or when the second air deflector 20 is rotatably connected to the lower end 107, the rotation angle of the second air deflector 20 is b2, 0°≤b2≤45°. For example, b1 can take values ​​of 0°, 45°, 60°, and 180°; in contrast, b2 can take values ​​of 0°, 15°, 30°, and 45°.

[0052] Preferably, the shape of the inner side surface of the first air guide plate 10 adjacent to the second air guide plate 20 is adapted to the shape of the surface of the second air guide plate 20. By providing the shapes of the surfaces of the first air guide plate 10 and the second air guide plate 20 adjacent to each other, the airflow directed from the air outlet 103 is reduced from partially entering the gap formed between the first air guide plate 10 and the second air guide plate 20, thereby reducing the efficiency of thermal interaction between the indoor unit 100 and the indoor environment.

[0053] Preferably, the second air guide plate 20 is made of transparent material.

[0054] On the other hand, the embodiment of the present invention further provides an air conditioner. Correspondingly, in this embodiment, the technical effects corresponding to any indoor unit 100 in the above embodiments can be achieved, which will not be described in detail here.

[0055] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
