Please refer to Figures 1 to 3, Figure 1 is a schematic diagram of a wall-mounted air conditioner indoor unit 1 according to an embodiment of the present invention, Figure 2 is a wall-mounted air conditioner indoor unit 1 according to an embodiment of the present invention when the second arm 50 is in the first position A cross-sectional view of the air-conditioning indoor unit 1, FIG. 3 is a cross-sectional view of the wall-mounted air-conditioning indoor unit 1 when the second arm 50 is in the second position according to an embodiment of the present invention, wherein the dotted arrows in FIG. 3 indicate the flow of air flow path.

The present invention proposes a wall-mounted air conditioner indoor unit 1 , and the wall-mounted air conditioner indoor unit 1 may generally include a casing 10 , a heat exchanger 20 and a heat exchange fan 30 . The casing 10 serves as the casing of the indoor unit 1 and protects the entire indoor unit 1. The casing 10 is provided with an air inlet 12 and an air outlet 13. The inside of the casing 10 defines an air supply duct 14 and a heat exchange space 16 for heat exchange. The heat exchanger 20 and the heat exchange fan 30 are installed in the heat exchange space 16. The heat exchanger 20 can exchange heat with the indoor airflow entering from the air inlet 12. The air outlet end of the heat exchange fan 30 faces the air supply duct 14 inlet end, To impel the airflow after heat exchange with the heat exchanger 20 to form the air supply air flow and send it into the air supply air duct 14, the outlet end of the air supply air duct 14 can also be connected to the air outlet 13, so that the air supply air flow can flow from the outlet The tuyere 13 discharges into the room, and then regulates the room temperature.

In this embodiment, the wall-mounted air conditioner indoor unit 1 may further include an outer wind deflector 40 , a second rotating arm 50 and a connecting rod 60 .

The outer wind deflector 40 may include a main body plate 42 and a first rotating arm 44. The main body plate 42 is arranged at the air outlet 13 for opening and closing the air outlet 13. The first end of the first rotating arm 44 is formed on the main body plate 42. The inner surface extends from the first end thereof in a direction away from the main body plate 42 . The first end of the second rotating arm 50 is hinged to the casing 10 and extends from the first end toward the air supply duct 14 . The second end of the second rotating arm 50 is hinged to the second end of the first rotating arm 44 . A first end of the connecting rod 60 is hinged to the first rotating arm 44 , and a second end of the connecting rod 60 is hinged to the casing 10 . The second rotating arm 50 can also be controlled to swing between the first position and the second position. When the second rotating arm 50 is in the first position, the main body plate 42 is in the position of closing the air outlet 13. When the second rotating arm During the swinging process from the first position to the second position, the first rotating arm 44 and the connecting rod 60 are driven to rotate at the same time, so that the main body plate 42 exposes the air outlet 13 .

The first end of the first rotating arm 44 can be integrally formed with the inner surface of the main body plate 42 , and the inner surface of the main body plate 42 can be understood as the surface facing inward when the main body plate 42 is in the position of closing the air outlet 13 . The second rotating arm 50 extends from the air supply duct 14, and the second end of the second rotating arm 50 is connected to the second end of the first rotating arm 44, that is, when the main body plate 42 is in the position of closing the air outlet 13, The first rotating arm 44 must also be located in the air supply duct 14 .

In this embodiment, the first end of the second rotating arm 50 and the casing 10 can be hinged through a rotating shaft. Similarly, the second end of the second rotating arm 50 is connected to the second end of the first rotating arm 44 and the connecting rod The first end of the connecting rod 60 and the casing 10 , and the second end of the connecting rod 60 and the first rotating arm 44 can respectively be articulated through rotating shafts.

Please refer to Fig. 2 and Fig. 3, in this embodiment, since the first pivoting arm 44, the second pivoting arm 50 and the connecting rod 60 are connected together in the form of a hinge (that is, a rotating pair), the first pivoting arm 44. The second rotating arm 50 and the connecting rod 60 can form a connecting rod mechanism to drive the main body plate 42 connected to the first end of the first rotating arm 44 to rotate relative to the air outlet 13 , so as to open and close the air outlet 13 . Further, since the relative position of the main body plate 42 and the air outlet 13 can be regarded as rotating in a plane, the link mechanism can also be a planar link mechanism, that is, the first rotating arm 44, the second rotating arm 50 and The connecting rods 60 are in the same plane.

In this embodiment, the second rotating arm 50 can be used as the active part of the link mechanism, and the first rotating arm 44 and the connecting rod 60 can be used as the driven parts. The second rotating arm 50 rotates toward the direction close to the air outlet 13 after receiving the external driving force, and drives the first rotating arm 44 and the connecting rod 60 to rotate in the same direction, so that the main body plate 42 leaves the position for closing the air outlet 13 and moves toward Rotate in a direction away from the air outlet 13 , and finally when the second rotating arm 50 rotates to the second position, the main body plate 42 will fully open the air outlet 13 to improve the air outlet efficiency.

Because the flow velocity of the air supply air at the air outlet 13 is relatively large, according to the Bernoulli effect, the pressure at the air outlet 13 is relatively lower than that in the room, so when the second rotating arm 50 is in the second position, the pressure difference will The airflow in the lower room can quickly enter the air guide duct 46 formed by the main body plate 42 and the bottom wall 18 of the casing 10, and flow toward the direction of the air outlet 13. Mix at the tuyere 13 to form a mixed air flow to increase the air output.

In addition, since there is a temperature difference between the indoor airflow and the air supply airflow, the indoor airflow passing through the draft duct 46 can also adjust the temperature of the air supply airflow at the air outlet 13 without affecting the overall cooling or heating efficiency. For example, when the indoor unit 1 is in the cooling mode, the indoor air flow through the air duct 46 can increase the temperature of the air supply air at the air outlet 13, so that the air flow discharged from the air supply duct 14 not only has a large flow rate, but also has a soft temperature. It is beneficial to improve the user experience.

Please refer to FIG. 3 , in some embodiments, when the second rotating arm 50 is in the second position, the main body plate 42 is inclined upward from back to front, so that when the indoor unit 1 is in the cooling mode, the air mixture is guided to be discharged upward, Further reduce the probability of cold air blowing directly to users and improve user experience. For example, the entire deck of the main body panel 42 may slope upward from back to front. In other embodiments, only the front deck of the body panel 42 may be sloped upwardly from rear to front.

Please refer to Fig. 3 and Fig. 4. Fig. 4 is a cross-sectional view of the wall-mounted air conditioner indoor unit 1 when the main body panel 42 is in the air distribution position according to an embodiment of the present invention. The dotted arrows in Fig. 4 indicate the flow path of the airflow. In some embodiments, the connecting rod 60 can also be configured to be telescopic along its length direction. When the second rotating arm 50 is in the second position, the connecting rod 60 is stretched in a controlled manner, so as to make the outer wind deflector 40 integrally rotate around the The second end of the second rotating arm 50 rotates upwards, and then the main body plate 42 is rotated to a position in front of the air outlet 13 and its inner surface faces the air outlet 13, that is, the indoor unit 1 is switched from the state shown in FIG. 3 into the state shown in Figure 4.

In this embodiment, since the first end of the connecting rod 60 is hinged to the casing 10, the second end of the connecting rod 60 is hinged to the first rotating arm 44.
