[0048] Figure 1 This is a schematic structural diagram of the indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 8 This utility model provides a wall-mounted air conditioner indoor unit, including a housing 100 and an air guiding device. The housing 100 is sequentially provided with a horizontally extending upper air outlet 400, a main air outlet 300, and a lower air outlet 500. The main air outlet 300 is adjacent to the upper air outlet 400, and the lower air outlet 500 is adjacent to the main air outlet 300. The air guiding device includes at least one air guide plate, rotatably disposed at the main air outlet 300, to open the main air outlet 300 and guide the airflow out of the main air outlet 300, or to close the main air outlet 300.

[0049] In this embodiment, the three air outlets—upper air outlet 400, main air outlet 300, and lower air outlet 500—are arranged more compactly. The upper air outlet 400, main air outlet 300, and lower air outlet 500, in conjunction with the air guiding device, can achieve multi-dimensional air delivery. For example, functions such as conventional hot and cold air swing, unique surround airflow, and rapid temperature equalization with surround airflow can significantly increase the air outlet angle, allowing the indoor unit to blow cold air upwards at a large angle and hot air downwards, improving the user's airflow experience and enhancing air delivery comfort.

[0050] In some embodiments of this utility model, the ratio of the width W1 of the upper air outlet 400 to the width W3 of the main air outlet 300 is 0.22 to 0.26. The ratio of the width W2 of the lower air outlet 500 to the width W3 of the main air outlet 300 is 0.22 to 0.26. The ratio between the width W1 of the upper air outlet 400 and the width W2 of the lower air outlet 500 is 0.8 to 1.2.

[0051] In this embodiment, the width ratio of the upper air outlet 400, the main air outlet 300 and the lower air outlet 500 is defined, with the main air outlet 300 having the largest width, and the airflow mainly blown out from the main air outlet 300.

[0052] Preferably, in some embodiments of this utility model, the width W1 of the upper air outlet 400 is equal to the width W2 of the lower air outlet 500 to ensure consistent appearance.

[0053] In some embodiments of this utility model, such as Figures 1 to 5As shown, the width W1 of the upper air outlet 400 is less than the width W3 of the main air outlet 300, and the ratio between the spacing distance of the main air outlet 300 and the upper air outlet 400 and the width W3 of the main air outlet 300 is less than or equal to 0.10. The width W2 of the lower air outlet 500 is less than the width W3 of the main air outlet 300, and the ratio between the spacing distance of the main air outlet 300 and the lower air outlet 500 and the width W3 of the main air outlet 300 is less than or equal to 0.09. In the embodiment, the spacing distance of the main air outlet 300 and the upper air outlet 400 and the spacing distance of the main air outlet 300 and the lower air outlet 500 are both small, so that the influence of the spacing on the air flow is small, and the air flow can be reduced as much as possible. Moreover, the arrangement of the upper air outlet 400, the main air outlet 300 and the lower air outlet 500 is facilitated, and the size of the shell in the up-down direction is saved.

[0054] In some other embodiments of the present application, the upper air outlet 400 and the main air outlet 300 are communicated, and the boundary line is located at the upper edge of the air guide device.

[0055] In some other embodiments of the present application, the lower air outlet 500 and the main air outlet 300 are communicated, and the boundary line is located at the lower edge of the air guide device.

[0056] In some embodiments of the present application, as shown in Figures 1 to 5 A grating structure 900 is arranged at the upper air outlet 400 and the lower air outlet 500. The grating structure 900 can divide the air flow through the upper air outlet 400 and the lower air outlet 500 into small air flows, so that the air outlet from the upper air outlet 400 and the lower air outlet 500 is soft.

[0057] In some other embodiments of the present application, as shown in Figures 1 to 5 A grating structure 900 is arranged at the upper air outlet 400 or the lower air outlet 500.

[0058] In some other embodiments of the present application, as shown in Figures 1 to 5 A microporous structure is arranged at the upper air outlet 400 and the lower air outlet 500. The microporous structure can divide the air flow through the upper air outlet 400 and the lower air outlet 500 into small air flows, so that the air outlet from the upper air outlet 400 and the lower air outlet 500 is soft.

[0059] In some other embodiments of the present application, as shown in Figures 1 to 5 A microporous structure is arranged at the upper air outlet 400 or the lower air outlet 500.

[0060] In some other embodiments of the present application, a wind guide plate for opening and closing the upper air outlet 400 is arranged at the upper air outlet 400.

[0061] In some other embodiments of the present application, a baffle plate is arranged at the lower air outlet 500 to open and close the lower air outlet.

[0062] In some embodiments of the present application, as shown in Figures 1 to 8 the air guiding device comprises a first baffle plate 601, a second baffle plate 603 and a blowing plate 602. The first baffle plate 601 is above the second baffle plate 603. The blowing plate 602 is arranged on the inner surface of the first baffle plate 601 in a spaced manner to rotate synchronously with the first baffle plate 601. When the air guiding device closes the main air outlet 300, the distance from the upper end of the blowing plate 602 to the first baffle plate 601 is greater than the distance from the lower end of the blowing plate 602 to the first baffle plate 601. In the present embodiment, the first baffle plate 601 and the second baffle plate 603 can internally rotate to guide air, increase the effective air outlet area for heating, improve the heating effect and comfort, and the blowing plate 602 lifts the air flow flowing to the blowing plate 602. The function of the blowing plate 602 is to mainly solve the air volume distribution of the upper air outlet 400 and the lower air outlet 500 when the main air outlet is closed, so as to realize the blowing of the air outlet and avoid the condensation of the upper air outlet.

[0063] In some embodiments of the present application, as shown in Figures 1 to 5 the distance from the lower end edge of the projection of the blowing plate 602 on the first baffle plate 601 to the lower end edge of the first baffle plate 601 is less than the distance from the upper end edge of the projection of the blowing plate 602 on the first baffle plate 601 to the upper end edge of the first baffle plate 601. That is, the blowing plate 602 is arranged at a lower position on the first baffle plate 601.

[0064] Further, in some embodiments of the present application, as shown in Figures 1 to 5 the ratio of the width L1 of the blowing plate 602 to the width L2 of the first baffle plate 601 is 0.21 to 0.35. The ratio of the distance L3 from the lower end edge of the projection of the blowing plate on the first baffle plate to the lower end edge of the first baffle plate to the width L2 of the first baffle plate 601 is 0.05 to 0.12. The ratio of the distance H from the lower end edge of the blowing plate 602 to the first baffle plate 601 to the width L2 of the first baffle plate 601 is 0.09 to 0.19. The first baffle plate 601 and the blowing plate 602 are both arc-shaped plates, and when the first baffle plate 601 closes the corresponding area of the main air outlet 300, the first baffle plate 601 and the blowing plate 602 are both arched downward. The ratio of the radius R3 of the blowing plate 602 to the radius R4 of the first baffle plate 601 is 0.20 to 0.24. The above limitations not only ensure the blowing capacity of the blowing plate 602, but also avoid the blowing plate 602 being too large to affect the air guiding effect of the first baffle plate 601.

[0065] In some embodiments of the present application, asFigures 1 to 5 As shown, the air conditioner indoor unit further comprises an air duct 200 arranged in the shell 100.
