[0038] Combination Figures 1 to 5 As shown, according to an embodiment of the present application, an indoor unit and an air conditioner having the same are provided.

[0039] Specifically, Figures 1 to 5 As shown, the indoor unit includes a housing 10, a panel body and an air guide plate assembly. The panel body is connected to the housing 10, and the panel body has an air outlet 11. A panel 20 is arranged on the panel body. The air guide plate assembly includes a plurality of air guide plates, at least two of which cooperate to close the air outlet 11, and an end of one of the two air guide plates that close the air outlet 11 is located outside the panel 20 to cover a portion of the outer surface of the panel 20.

[0040] By applying the technical solution of the present invention, an air guide plate assembly is provided, and the air guide plate can be adjusted to a large extent to achieve the purpose of comfortable air supply, solve the problem that the air supply distance is not far and the cold wind blows on people when the air conditioner is cooling, solve the problem that the air outlet is exposed when the air conditioner is closed and the cooling and heating operations are unsightly, and at the same time solve the problem that the heating comfort of the air conditioner is poor and the hot air cannot fall to the ground.

[0041] like Figure 3 and Figure 4 As shown, the plurality of air guide plates include a first air guide plate 21, which is movably connected to the panel body, and has a first open position to open the air outlet 11, and a first closed position to close the air outlet 11. The first end of the first air guide plate 21 is arranged close to one side of the air outlet 11, and the second end of the first air guide plate 21 extends toward one side of the panel 20 in a vertical direction. When the first air guide plate 21 is located at the first closed position, the second end of the first air guide plate 21 is located on the outside of the panel 20. When the first air guide plate 21 is located at the first open position, a first air outlet channel 31 is formed between the surface of the second end of the first air guide plate 21 facing the panel 20 and the outer surface of the panel 20. Among them, Figure 3 The first air guide plate 21 is located at the first open position, Figure 4 The first air guide plate 21 is located at the first closed position. The first air guide plate 21 is arranged outside the panel, and the size of the air guide plate can be designed to be a maximum size structure, which plays a role in optimizing the air guide plate. Figure 4 As shown, the width of the first air guide plate 21 along the vertical direction is more than half of the width of the indoor unit casing along the vertical direction. At the same time, this arrangement allows the opening angle of the first air guide plate 21 to be greatly adjusted, thereby optimizing the airflow angle.

[0042] like Figure 3As shown, when the first air guide plate 21 is in the first open position, the length of the second end of the first air guide plate 21 shielding the panel 20 along the vertical direction is L1, and the length of the panel 20 along the vertical direction is L2, wherein 0.5×L2≤L1≤2×L2 / 3. This arrangement allows the air outlet 11 to be better shielded when the air conditioner is closed, thereby making the appearance of the air conditioner more beautiful.

[0043] like Figure 1 and Figure 4 As shown, in one embodiment of the present application, the plurality of air guide plates further include a second air guide plate 22, the second air guide plate 22 is movably connected to the panel body, the second air guide plate 22 has a second open position to open the air outlet 11, and the second air guide plate 22 has a second closed position to close the air outlet 11, when the first air guide plate 21 is in the first closed position, the first end of the first air guide plate 21 is arranged at a distance from the lower edge of the air outlet 11 to form a second air outlet channel 32, when the second air guide plate 22 is in the second closed position, the second air guide plate 22 is located between the first end of the first air guide plate 21 and the lower edge of the air outlet 11 to close the second air outlet channel 32. This arrangement allows the second air guide plate 22 to be greatly adjusted, and as shown in FIG. Figure 4 As shown, when the air conditioner is in heating operation, the first air guide plate 21 is located at the first closed position and the second air guide plate 22 is located at the second open position, the second air outlet channel 32 can guide air downward. Figure 1 As shown, when the first air guide plate 21 is located at the first closed position and the second air guide plate 22 is located at the second closed position, the first air guide plate 21 and the second air guide plate 22 cooperate to close the air conditioner and shield the air outlet 11 from the outside, thereby beautifying the appearance.

[0044] like Figure 4 As shown, in one embodiment of the present application, when the second air guide plate 22 is located at the second open position, the second air guide plate 22 is located outside the first air guide plate 21, and the first end of the second air guide plate 22 is arranged close to the first end of the first air guide plate 21, and the second end of the second air guide plate 22 is extended away from one side of the first air guide plate 21, and the surface of the second air guide plate 22 facing the second air outlet channel 32 forms the first air guide surface 221. This arrangement allows the inner surface of the second air guide plate 22 to guide the hot air when the air conditioner is in the heating state, so that the airflow more effectively guides the hot air to the ground, thereby improving the air supply comfort of heating.

[0045] like Figure 3As shown, in one embodiment of the present application, the plurality of air guide plates also include a third air guide plate 23, which is movably connected to the panel body, and has a first air guide position and a second air guide position. When the first air guide plate 21 is located at the first open position and the second air guide plate 22 is located at the second closed position, the third air guide plate 23 is located at the first air guide position, and the third air guide plate 23 is located on the inner side of the second air guide plate 22. The first end of the third air guide plate 23 is arranged close to the air duct surface 12 of the shell 10, and the second end of the third air guide plate 23 is arranged close to the first end of the first air guide plate 21. The second air guide surface 231 of the third air guide plate 23 on the side away from the second air guide plate 22 forms a flow surface with the air duct surface 12 and the inner surface of the first air guide plate 21. This arrangement allows the second air outlet duct 32 to be closed and the first air outlet duct 31 to be opened when the air conditioner is in cooling mode, so that the cold air can be delivered along the first air outlet duct 31 over a long distance to a place near the ceiling, allowing the cold air to blow higher and farther. Because cold air is heavier, shower-style cooling is achieved, and it can prevent people from being blown by the cold air, thereby improving the comfort of cooling and air supply.

[0046] like Figure 4 As shown, when the first air guide plate 21 is in the first closed position and the second air guide plate 22 is in the second open position, the third air guide plate 23 is in the second air guide position, and the third air guide plate 23 is located in the accommodation cavity 13 formed by the first air guide plate 21 and the upper edge of the air outlet 11, and the first end of the third air guide plate 23 is arranged close to the first air guide plate 21, and the second end of the third air guide plate 23 is arranged close to the upper edge of the air outlet 11, and the second air outlet channel 32 is formed between the second air guide surface 231 and the air duct surface 12 and the first end of the first air guide plate 21. This arrangement allows the air conditioner to be in the heating state and the accommodation cavity 13 is formed, and the first air guide plate 21 can also be opened to a certain angle, and the hot air is blown out from the second air outlet channel 32 and blown out to the lower front of the ground, so as to achieve a carpet-like heating effect. At the same time, through the second air guide surface 231, the airflow can more effectively guide the hot air to the ground, thereby improving the comfort of air supply for heating. Furthermore, when the second air guide plate 22 is in the open state, the air outlet 11 can be shielded, thereby beautifying the appearance of the indoor unit.

[0047] like Figure 5 As shown, in one embodiment of the present application, when the second air guide plate 22 is located at the second open position, the second air guide plate 22 is located in the accommodation cavity 13 formed by the first air guide plate 21 and the upper edge of the air outlet 11. This arrangement makes it impossible to see the second air guide plate 22 from the appearance, further beautifying the appearance of the air conditioner.

[0048] In another embodiment of the present application, the plurality of air guide plates further include a third air guide plate 23, the third air guide plate 23 is movably connected to the panel body, the third air guide plate 23 has a first air guide position and a second air guide position, when the first air guide plate 21 is in the first open position and the second air guide plate 22 is in the second closed position, the third air guide plate 23 is in the first air guide position, the third air guide plate 23 is located on the inner side of the second air guide plate 22, the first end of the third air guide plate 23 is arranged close to the air duct surface 12 of the housing 10, the second end of the third air guide plate 23 is arranged close to the first end of the first air guide plate 21, and the second air guide surface 231 of the third air guide plate 23 on the side away from the second air guide plate 22 forms a flow surface with the air duct surface 12 and the inner surface of the first air guide plate 21. This arrangement ensures that when the air conditioner is in a cooling state, the cold air is blown out along the flow surface formed by the second air guide surface 231 and the air duct surface 12 and the inner surface of the first air guide plate 21, further improving the comfort of cooling air supply.

[0049] like Figure 5 As shown, when the first air guide plate 21 is located at the first closed position and the second air guide plate 22 is located at the second open position, the third air guide plate 23 is located at the second air guide position, the second air guide plate 22 is located between the third air guide plate 23 and the first air guide plate 21, and the first end of the third air guide plate 23 is arranged close to the first air guide plate 21, and the second end of the third air guide plate 23 is arranged close to the upper edge of the air outlet 11, and the second air guide surface 231 and the air duct surface 12 and the first end of the first air guide plate 21 form a second air outlet channel 32. This arrangement ensures that when the air conditioner is in the heating state, hot air can only be blown out from the second air outlet channel 32, and downward air outlet can be achieved.

[0050] The third air guide plate 23, the second air guide plate 22 and the first air guide plate 21 are each provided with a driving mechanism, the driving mechanism corresponding to the third air guide plate 23 is used to drive the third air guide plate 23 to move to the first air guide position and the second air guide position, the driving mechanism corresponding to the second air guide plate 22 is used to drive the second air guide plate 22 to be located at the second open position and the second closed position, and the driving mechanism corresponding to the first air guide plate 21 is used to drive the first air guide plate 21 to be located at the first open position and the first closed position. This arrangement facilitates the control of the opening and closing states of the air guide plate assembly, and further facilitates the control of the air conditioner to switch between the cooling and heating modes. The driving mechanism may include a motor, a gear provided on the motor output shaft, and a driving rack structure matched with the gear.

[0051] like Figure 3As shown, when the first air guide plate 21 is located at the first open position, the second air guide plate 22 is located at the second closed position, and the third air guide plate 23 is located at the first air guide position, a gap is provided between the end of the first end of the first air guide plate 21 and the second air guide plate 22 and the third air guide plate 23. In this way, when cooling, cold air evenly passes through the inner and outer surfaces of the first air guide plate 21, thereby effectively preventing condensation from occurring on the first air guide plate 21.

[0052] The indoor unit in the above embodiment can also be used in the technical field of air-conditioning equipment. That is, according to another aspect of the present application, an air conditioner is provided, including an indoor unit, and the indoor unit is the indoor unit in the above embodiment.

[0053] According to another specific embodiment of the present application, a control method for an indoor unit is provided, and the control method is used to control the indoor unit in the above embodiment, and the control method includes the following steps: when the indoor unit turns on the cooling mode, the first air guide plate 21 is controlled to be located at the first open position, the second air guide plate 22 is controlled to be located at the second closed position, and the third air guide plate 23 is controlled to be located at the first air guide position. This arrangement ensures that when the indoor unit turns on the cooling mode, the second air outlet channel 32 is in a closed state, and the cold air can only be blown out from the first air outlet channel 31, realizing single upper air outlet and improving the comfort of cooling air supply.

[0054] The control method further includes: when the indoor unit turns on the heating mode, controlling the first air guide plate 21 to be located at the first closed position, the second air guide plate 22 to be located at the second open position, and the third air guide plate 23 to be located at the second air guide position. This arrangement makes it easy to control the first air guide plate 21, the second air guide plate 22, and the third air guide plate 23 to be at the optimal air guide position when the indoor unit turns on the heating mode.

[0055] The control method further includes: when the indoor unit is in the heating mode, controlling the first air guide plate 21 to be located at the first closed position, controlling the third air guide plate 23 to rotate toward the inside of the housing 10 by a first preset angle and then move to the avoidance position, controlling the second air guide plate 22 to move along the outer side of the third air guide plate 23 to the second open position, and controlling the third air guide plate 23 to rotate from the avoidance position by a second preset angle and then be located at the second air guide position. This arrangement facilitates the control of the movement process of the first air guide plate 21, the second air guide plate 22 and the third air guide plate 23 when the indoor unit is in the heating mode, thereby placing the air guide plate in the optimal air guide position.

[0056] Before the control method controls the second air guide plate 22 to move to the second open position along the outer side of the third air guide plate 23, the control method further includes: after controlling the first air guide plate 21 to open to the third preset angle, controlling the second air guide plate 22 to move to the second open position along the outer side of the third air guide plate 23. This arrangement can facilitate the opening of each air guide plate and avoid the problem of interference between the air guide plates.

[0057] The control method controls the second air guide plate 22 to move to the second open position along the outer side of the third air guide plate 23, and then controls the first air guide plate 21 to move to the first closed position. This arrangement facilitates the control of the movement of the first air guide plate 21, ensuring that when the indoor unit turns on the heating mode, the first air guide plate 21 is finally in the heating position, ensuring that the first air outlet channel 31 is closed, and at the same time, the second air guide plate 22 is not visible from the appearance, making the appearance of the air conditioner more beautiful.

[0058] By applying the technical solution of the present application, the air conditioner can achieve a relatively comfortable single-up and single-down air supply effect, thereby improving the comfort of cooling and heating air supply. Figure 1 As shown. The appearance of the whole machine is composed of the first air guide plate 21, the second air guide plate 22 and the panel 20, and there is also a third air guide plate 23 inside the air duct surface 12. According to the normal installation position of the air conditioner, the second air guide plate 22 is located below the air conditioner, and the first air guide plate 21 is located at the lower front of the air conditioner. It is an extra-large air guide plate, which covers 1 / 2 to 2 / 3 of the front panel 20 of the air conditioner, that is, it serves as the air guide plate of the air conditioner and the main appearance of the front of the air conditioner.
