The second air supply outlet 12 is rotatably provided with an air deflector 40 for adjusting the ratio of the air flow entering the casing 10 to the first air supply outlet 11 and the second air supply outlet 12 and adjusting the front and back air outlet direction of the second air supply outlet 12. The ratio of the air flowing to the first air supply outlet 11 and the second air supply outlet 12 can be controlled by adjusting the angle of the air deflector 40, so as to adjust the air output of the two air supply outlets. The wall-mounted air conditioner indoor unit 100 of the embodiment of the invention is provided with the first air supply outlet 11 and the second air supply outlet 12, so that the wall-mounted air conditioner indoor unit 100 has multiple air outlet forms, meets various different requirements of users, can supply air only through the first air supply outlet 11, can supply air only through the second air supply outlet 12, can supply air through the first air supply outlet 11 and the second air supply outlet 12 simultaneously, and can adjust the air output of the first air supply outlet 11 and the second air supply outlet 12. As shown in fig. 6 and 7, arrows show the airflow direction of the two air outlet modes. In fig. 6, the slide plate 70 is not opened, the first air blowing port 11 is closed, and air is blown only through the second air blowing port 12. In fig. 7, the slide plate 70 is opened to blow air through the first and second air blowing ports 11 and 12. The second supply port 12 may be closed (for example, the air guide plate 40 may be disposed horizontally), and only the first supply port 11 may supply air. In addition, the wall-mounted air conditioning indoor unit 100 according to the embodiment of the present invention may further include a plurality of swing blades rotatably disposed at the first air supply outlet 11 and/or the second air supply outlet 12, and configured to adjust an air outlet direction of the first air supply outlet 11 and/or the second air supply outlet 12.
With continued reference to fig. 6 and 7, the wall-mounted type air conditioning indoor unit 100 further includes: volute tongue 20, volute 21, heat exchanger 50 and crossflow blower 60. The volute tongue 20 is disposed in the housing 10. The volute 21 is formed in the housing 10 behind the volute tongue 20, and defines an air duct (not numbered) with the volute tongue 20. The volute 21 may be integrated on the rear frame 102. The heat exchanger 50 is disposed in the casing 10, and includes a first heat exchange section 51, a second heat exchange section 52 and a third heat exchange section 53 connected in a bent manner, and is disposed in the casing 10. According to simulation and actual measurement, the first heat exchange section 51 belongs to a high-speed area, and due to the influence of a front panel of a traditional hanging machine, the air inlet space of the traditional hanging machine is limited, available air inlet is less, and air inlet efficiency is lower. In the wall-mounted air conditioner indoor unit 100 according to the embodiment of the present invention, the sliding plate 70 is disposed at the front side of the front frame 101, and the sliding plate 70 moves forward and upward, so that an air intake gap 701 is defined between the sliding plate 70 and the front frame 101, and the second air intake 14 at the front side of the front frame 101 can also intake air, so as to meet the requirement of large air intake, and meanwhile, the air flow entering the casing 10 through the second air intake 14 can more effectively utilize the first heat exchange section 51, thereby improving the heat exchange efficiency of the heat exchanger 50. The cross-flow fan 60 is disposed in the casing 10 and located in front of the heat exchanger 50, and is configured to promote indoor air to enter the casing 10 through the first air inlet 13 and the second air inlet 14, so that heat exchange between the indoor air and the heat exchanger 50 is completed, and then the cross-flow fan blows air to the air duct. The air duct is configured such that the inlet faces the heat exchanger 50 and the outlet communicates with the first supply air outlet 11 and the second supply air outlet 12, so that the air exchanged with heat by the heat exchanger 50 reaches the first supply air outlet 11 and the second supply air outlet 12 through the air duct.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
