[0037] Figure 1 is a cross-sectional view of the vertical air conditioner indoor unit of an embodiment of the present application, with reference to Figures 2 to 4 The vertical air conditioner indoor unit of the embodiment of the present application includes an air outlet column 10 and an air guide device.

[0038] The air outlet column 10 is vertically arranged, and a first air outlet 111 and a second air outlet 112 are formed on the front side of the air outlet column 10. An air outlet air duct 121 and a bypass air duct 122 are arranged in the air outlet column 10, and the air outlet air duct 121 is in communication with the first air outlet 111, and the bypass air duct 122 is in communication with the second air outlet 112. The inlet of the bypass air duct 122 is located on one side wall of the air outlet air duct 121.

[0039] The air guide device is arranged at the air outlet, and the air guide device comprises a first air guide plate 151 rotating around a first vertical axis, so that the first air guide plate 151 has at least a first position.

[0040] The first air guide plate 151 has a first edge and a second edge arranged vertically. As shown in Figure 1 and Figure 2 When the first air guide plate 151 is in the first position, the second edge is adjacent to the front part of the inlet of the bypass air duct 122, and the first edge is located behind the second edge in the lateral direction, so as to control the air volume flowing to the first air outlet 111 and the second air outlet 112.

[0041] In some alternative embodiments of the present application, when the first air guide plate 151 is in the first position, the second edge is located in the front part of the inlet of the bypass air duct 122.

[0042] In some alternative embodiments of the present application, when the first air guide plate 151 is in the first position, the first edge is flush with the second edge in the front-rear direction.

[0043] In some alternative embodiments of the present application, when the first air guide plate 151 is in the first position, the first edge is located in front of the second edge in the lateral direction, and the angle between the plane where the first edge and the second edge are located and the vertical plane extending in the lateral direction is less than a preset angle. Preferably, the preset angle is 5-30° (for example, 5°, 7°, 8°, 9°, 10°, 15°, 20°, 25° or 30°), and further preferably, the preset angle is 10°.

[0044] In these embodiments, when the first air guide plate 151 is in the first position, the first air guide plate 151 can close at least part of the first air outlet 111.

[0045] In the embodiments, since the air outlet column 10 has the first air outlet 111 and the second air outlet 112, and the first air deflector 151 is arranged at the first air outlet 111, when the first air deflector 151 is located at the first position, the air flow is more conducive to entering the bypass air duct 122. Therefore, by adjusting the rotation angle of the first air deflector 151, the air volume of the air flow sent to the first air outlet 111 and the second air outlet 112 can be adjusted, and the air outlet column 10 can have multiple air outlet modes. For example, the air outlet column 10 can select the second air outlet 112 to blow air alone, or the first air outlet 111 and the second air outlet 112 to blow air simultaneously, and when the first air outlet 111 and the second air outlet 112 blow air simultaneously, the air volume can be increased. In summary, the application not only increases the adjustment range of the air volume of the air conditioner indoor unit, but also increases the adjustment range of the air outlet angle of the air conditioner indoor unit. Multiple air outlet modes enable the air conditioner indoor unit to meet the needs of users, thereby improving the comfort of the air conditioner indoor unit.

[0046] As shown in Figure 3 some optional embodiments of the application, the first air deflector 151 also has a second position, in which the first edge is adjacent to the front end of the side wall, and the second edge is located at the rear side of the first edge.

[0047] When the first air deflector 151 is located at the second position, the first air deflector 151 can open at least part of the first air outlet 111. Compared with the first position, when the first air deflector 151 is located at the second position, the air volume of the air flow sent to the first air outlet 111 is increased, and the air volume of the air flow sent to the second air outlet 112 is reduced.

[0048] As shown in Figures 1-4 some optional embodiments of the application, the air deflector device further comprises a second air deflector 152 rotating around a second vertical axis, and the second air deflector 152 is arranged on the side of the first air deflector 151 away from the side wall.

[0049] In the embodiments, the first air deflector 151 and the second air deflector 152 are independently controlled. By arranging two air deflectors, it is more conducive to adjusting the air volume of the first air outlet 111 and the second air outlet 112, and it is more convenient to adjust different air outlet angles, so that the air supply mode of the air outlet column 10 can be more diversified.

[0050] As shown in Figures 1-4 some optional embodiments of the application, the second air deflector 152 has at least a third edge and a fourth edge arranged vertically.

[0051] The second air deflector 152 has at least a third position and a fourth position.

[0052] As shown inFigure 1 As shown in FIG. 6, when the first air deflector 151 is in the first position and the second air deflector 152 is in the third position, the fourth edge is adjacent to or at the back of the first edge, and the third edge is adjacent to the front of the other side wall of the air outlet duct 121, so that the air flow is all into the second air outlet 112.

[0053] As shown in FIG. 7, when the first air deflector 151 is in the first position and the second air deflector 152 is in the fourth position, the third edge is adjacent to the front of the air outlet column 10, the fourth edge is at the back of the third edge, and the first air outlet 111 is partially open, so that the air flow is into the first air outlet 111 and the second air outlet 112. Figure 2

[0054] As shown in FIG. 8, when the first air deflector 151 is in the second position and the second air deflector 152 is in the fourth position, the first air outlet 111 is fully open, and the air flow into the bypass duct 122 is less than the air flow into the air outlet duct 121. Figure 3 Further, the second air outlet 112 is a breeze outlet. Through the above arrangement, the air conditioner indoor unit has a full breeze mode, a half breeze mode and a slight breeze mode.

[0055] As shown in FIG. 9, when the air conditioner indoor unit operates in the full breeze mode, the first air deflector 151 is in the first position and the second air deflector 152 is in the third position, the first air deflector 151 and the second air deflector 152 are both inside the air outlet duct 121, the first air outlet 111 is not open, only the breeze outlet is open, and the air volume of the breeze outlet is large.

[0056] Figure 1 As shown in FIG. 10, when the air conditioner indoor unit operates in the half breeze mode, the first air deflector 151 is in the first position and the second air deflector 152 is in the fourth position, the first air outlet 111 is partially open, and the first air outlet 111 and the breeze outlet are both open, and the air volume of the breeze outlet is small.

[0057] As shown in FIG. 11, when the air conditioner indoor unit operates in the slight breeze mode, the first air deflector 151 is in the second position and the second air deflector 152 is in the fourth position, the first air outlet 111 is fully open, and the first air outlet 111 and the breeze outlet are both open, and the air volume of the breeze outlet is very small. Figure 2 As shown in FIG. 12, in some optional embodiments of the present application, the first air deflector 151 further has a fifth position, and the second air deflector 152 further has a sixth position.

[0058] Figure 3 As shown in FIG. 13, in some optional embodiments of the present application, the first air deflector 151 further has a fifth position, and the second air deflector 152 further has a sixth position.

[0059] As shown in FIG. 14, in some optional embodiments of the present application, the first air deflector 151 further has a fifth position, and the second air deflector 152 further has a sixth position. Figure 4 As shown in FIG. 15, in some optional embodiments of the present application, the first air deflector 151 further has a fifth position, and the second air deflector 152 further has a sixth position.​​​

[0060] In the fifth position and the sixth position, the first edge is adjacent to the front of the side wall, the fourth edge is adjacent to the front of the other side wall, the second edge is connected with the third edge, and the first air outlet 111 is closed.

[0061] That is, in the fifth position and the sixth position, the first air deflector 151 and the second air deflector 152 are connected.

[0062] Specifically, when the first air deflector 151 is in the fifth position and the second air deflector 152 is in the sixth position, the first air deflector 151 and the second air deflector 152 are located at the first air outlet 111 to close the first air outlet 111, and only the second air outlet 112 can blow air. However, when the first air deflector 151 is in the first position and the second air deflector 152 is in the third position, the first air deflector 151 and the second air deflector 152 are both located inside the air outlet air duct 121, which can reduce the flow path of the airflow, and is more conducive to the airflow in the air outlet air duct 121 flowing into the bypass air duct 122, and can also reduce noise.

[0063] In some optional embodiments of the present application, the inlet of the bypass air duct 122 is provided with an air inlet structure 13, and a gap hole 14 for inserting the first air deflector 151 is arranged between the front vertical edge of the inlet of the bypass air duct 122 and the air inlet structure 13.

[0064] Specifically, when the first air deflector 151 is in the first position, the second edge of the first air deflector 151 is inserted into the gap hole 14.

[0065] In some optional embodiments of the present application, the first air deflector 151 has a convex surface and a concave surface arranged oppositely, and in the first position, the convex surface faces backward.

[0066] In the present embodiment, through the above arrangement, the flow resistance of the airflow can be reduced, which is more conducive to the airflow flowing into the bypass air duct 122, and can also reduce noise.

[0067] In some optional embodiments of the present application, the second air deflector 152 has a convex surface and a concave surface arranged oppositely, and in the third position, the convex surface faces backward.

[0068] In the present embodiment, through the above arrangement, the flow resistance of the airflow can be reduced, which is more conducive to the airflow flowing into the bypass air duct 122, and can also reduce noise.

[0069] In some optional embodiments of the present application, the first air outlet 111 and the second air outlet 112 are both vertical strip-shaped.

[0070] In the embodiment, the air outlet in the vertical strip shape can avoid temperature stratification in the indoor space, so that the indoor temperature is uniform in the up-down direction.

[0071] In some alternative embodiments of the present application, the air inlet structure 13 is an air inlet grille. Specifically, the air flow is scattered by the air inlet grille into a micro-wind, so that the air outlet is softer.

[0072] In some alternative embodiments of the present application, the air inlet structure 13 is a microporous plate. Specifically, the air flow is scattered by the microporous plate into a micro-wind, so that the air outlet is softer.

[0073] In some alternative embodiments of the present application, the air outlet column 10 is two, and the two air outlet columns 10 are arranged at intervals to form an air guide interval 20 between the two air outlet columns 10.

[0074] Specifically, when the two air outlet columns 10 blow air forward, the air in the air guide interval 20 is driven to flow forward by negative pressure, so that the air is mixed with the air blown by the two air outlet columns 10. In the case of refrigeration, the air outlet temperature is improved, so that the wind is not too hard, and the soft wind effect is achieved.

[0075] In some alternative embodiments of the present application, the air outlet column 10 is two, and the first air outlet 111 and the second air outlet 112 are arranged on the front side of each air outlet column 10. The two air outlet columns 10 are symmetrically arranged about a vertical reference surface extending forward and backward. The symmetrically arranged air outlet columns 10 make the appearance of the indoor air conditioner stable and meet the aesthetic taste of Chinese people.

[0076] In the embodiment, by arranging two air outlet columns 10, the air conditioner can have more air outlet modes. For example, the two air outlet columns 10 operate different air outlet modes or the same air outlet mode. The two air outlet columns 10 can select different air outlet angles. Therefore, compared with a single air outlet column 10, the two air outlet columns 10 can further increase the adjustment range of the air outlet amount of the indoor air conditioner and further increase the adjustment range of the air outlet angle of the indoor air conditioner.

[0077] In some alternative embodiments of the present application, the air guide interval 20 only includes an air inlet section and an air outlet section connected to each other. The width of the air outlet section gradually increases along the flow direction of the air flow. The width of the air inlet section gradually decreases along the flow direction of the air flow. The above arrangement of the air guide interval 20 is beneficial to the air on the rear side of the air guide interval 20 entering and is also beneficial to the air in the air guide interval 20 flowing forward.

[0078] In some alternative embodiments of the present application, the indoor heat exchanger 16 and the indoor fan 17 are arranged in each air outlet column 10.

[0079] Specifically, the indoor unit of the air conditioner comprises two indoor heat exchangers 16, which are arranged in parallel. The two indoor heat exchangers 16 are connected with a flow path control device, which is configured to control the two indoor heat exchangers 16 to work simultaneously or only one of the indoor heat exchangers 16 to work. By arranging the flow path control device and the two heat exchangers, heat exchange air can be discharged from one air outlet column 10. Non-heat exchange air (which can be indoor air or fresh air) can be discharged from the other air outlet column 10. In particular, during refrigeration operation, refrigeration air is discharged from one air outlet column 10, and non-heat exchange air is discharged from the other air outlet column 10. The non-heat exchange air has a long blowing distance and can disturb the flow of indoor air, thereby dispersing the refrigeration air, achieving wide-area temperature regulation and comfortable air supply, and realizing the scenario of cool air supply and improving the user experience.

[0080] In some alternative embodiments of the present application, the flow path control device comprises two electronic on-off valves, which are respectively connected in series with the corresponding indoor heat exchangers 16. The electronic on-off valves are connected in series with the heat exchangers, and the flow path of the working medium in the heat exchanger is controlled by the electronic on-off valves, which is stable and reliable in operation.

[0081] In some alternative embodiments of the present application, the flow path control device comprises a three-way valve. The three-way valve comprises three openings, i.e. a first opening, a second opening and a third opening. The first opening is used to be connected with the four-way valve, and the second opening and the third opening are respectively connected with the two indoor heat exchangers 16. By controlling the on-off of the first opening and the second opening of the three-way valve, the on-off of the flow path of the working medium in each indoor heat exchanger 16 is controlled, which is stable and reliable in operation. That is, by controlling the opening degree of the three-way valve, the refrigerant can flow to the left air outlet column, the right air outlet column or the left and right air outlet columns simultaneously, thereby realizing the function of double air outlet column control.

[0082] In some alternative embodiments of the present application, the air conditioner comprises three air outlet columns 10.

[0083] In some alternative embodiments of the present application, the air conditioner comprises one air outlet column 10.

[0084] In some alternative embodiments of the present application, the air conditioner comprises three air outlet columns 10.

[0085] At this point, those skilled in the art should recognize that, although the present application has been shown and described in detail in the above embodiments, many other variations or modifications can be directly determined or deduced from the disclosure of the present application according to the principles of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variations or modifications.
