[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] The wall-mounted indoor unit 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] like Figures 1-6 As shown, the wall-mounted indoor unit 1 according to an embodiment of the present utility model includes a housing 100 and a first air guide plate 21.

[0029] The front side of the casing 100 is provided with a front air outlet grille 12, and the bottom wall of the casing 100 is provided with a bottom air outlet 11. The wall-mounted indoor unit 1 is suitable for discharging air forward through the front air outlet grille 12 and discharging air downward through the bottom air outlet 11, so as to meet the different air discharge needs of the wall-mounted indoor unit 1. At the same time, the wall-mounted indoor unit 1 can also discharge air through the front air outlet grille 12 and the bottom air outlet 11 together, which can increase the air discharge area of ​​the wall-mounted indoor unit 1 and improve the cooling or heating efficiency of the wall-mounted indoor unit 1.

[0030] For example, when the wall-mounted indoor unit 1 blows out hot air to heat a designated area, the wall-mounted indoor unit 1 is suitable for blowing air downward through the bottom air outlet 11. Since hot air has a lower density and tends to rise, the wall-mounted indoor unit 1 blows air downward through the bottom air outlet 11, effectively achieving the effect of the heating airflow blowing downward toward the bottom air outlet 11. This solves the problem of poor downward airflow effect in traditional wall-mounted units, and improves the foot warming effect, the temperature rise rate, and the uniformity of heating stratification.

[0031] When the wall-mounted indoor unit 1 blows out cold air to cool a designated area, the wall-mounted indoor unit 1 can blow air forward through the front air outlet grille 12, which can avoid the cold air blowing directly on the user and improve the user's comfort.

[0032] The first air guide plate 21 is rotatably disposed inside the housing 100. The first air guide plate 21 is provided with a plurality of air dispersing holes 211. On the longitudinal section of the first air guide plate 21, the extension direction of the central axis of each air dispersing hole 211 intersects with the thickness direction of the first air guide plate 21. By controlling the position of the first air guide plate 21 and the orientation of the air dispersing holes 211, it is possible to control whether the air flowing through the air dispersing holes 211 is with the wind or suddenly turns.

[0033] The first air guide plate 21 has a first state and a second state. In the first state, the first air guide plate 21 rotates to block the front air outlet grille 12 to prevent airflow from flowing to the front air outlet grille 12. At this time, the first air guide plate 21 guides air to the bottom air outlet 11, so that the wall-mounted indoor unit 1 can discharge air through the bottom air outlet 11, so that the wall-mounted indoor unit 1 can discharge air downward through the bottom air outlet 11.

[0034] Specifically, when the first air guide plate 21 guides air to the bottom air outlet 11, the airflow direction through the diffuser hole 211 changes abruptly and turns, and the air does not pass through the diffuser hole 211, thereby ensuring the shielding effect of the first air guide plate 21 on the front air outlet grille 12, so as to prevent the wall-mounted indoor unit 1 from venting air from the front air outlet grille 12.

[0035] Because hot air has a lower density and tends to rise, the wall-mounted indoor unit 1 blows air downwards from the bottom air outlet 11, effectively achieving the effect of the heating airflow blowing downwards towards the bottom air outlet 11. This solves the problem of poor downward airflow effect in traditional wall-mounted units, and improves the foot warming effect, the temperature rise rate, and the uniformity of heating stratification.

[0036] In the second state, the first air guide plate 21 rotates to block the bottom air outlet 11. At this time, the first air guide plate 21 guides the air out through the front air outlet grille 12. The wall-mounted indoor unit 1 can then expel air forward through the front air outlet grille 12, which can prevent cold air from blowing directly on the user and improve the user's comfort.

[0037] Meanwhile, when the air flows to the bottom air outlet 11, the air flowing through the diffuser hole 211 is in the direction of the wind. At this time, the air can flow out through the diffuser hole 211 on the first air guide plate 21. The diffuser hole 211 can refine the air so that the wall-mounted indoor unit 1 blows out a breeze from the bottom air outlet 11 without being felt, thereby avoiding cold air blowing directly on the user.

[0038] When the first air guide plate 21 is in the second state, cold air can be discharged through the front air outlet grille 12 and the air diffuser 211. The air blown out from the front air outlet grille 12 will not blow directly on the user. The air diffuser 211 can refine the air so that the bottom air outlet 11 blows out a breeze that is imperceptible. At this time, the wall-mounted indoor unit 1 has a larger overall air outlet angle and more comfortable air supply. While ensuring the air volume, it can also prevent cold air from blowing directly on the user.

[0039] Understandably, by controlling the position of the first air guide plate 21 and the orientation of the air diffuser 211, it is possible to control whether the airflow passing through the air diffuser 211 is downstream or abruptly turns. This ensures that when the first air guide plate 21 is in the first state, the heating airflow does not pass through the air diffuser 211; and when the first air guide plate 21 is in the second state, the cooling airflow passes through the air diffuser 211, so that the first air guide plate 21 can fully match the needs of each mode.

[0040] For example, when the first air guide plate 21 is in the first state, the heating airflow can be directed downwards towards the bottom air outlet 11, resulting in better heating performance. When the first air guide plate 21 is in the second state, it can achieve imperceptible airflow, preventing the wall-mounted indoor unit 1 from blowing directly on the user, thus improving the user experience.

[0041] Therefore, according to the wall-mounted indoor unit 1 of this utility model embodiment, by providing air dissipation holes 211 on the first air guide plate 21, the first air guide plate 21 can switch between the first state and the second state, and can realize the heating airflow downward towards the bottom air outlet 11, the airflow without sensation, etc., so that the wall-mounted indoor unit has more air outlet modes to adapt to diverse scenarios and improve the user experience comfort.

[0042] The following description, with reference to the accompanying drawings, describes a wall-mounted indoor unit 1 according to a specific embodiment of the present invention.

[0043] In some specific embodiments of this utility model, such as Figures 1-6 As shown, the wall-mounted indoor unit 1 includes a housing 100 and a first air guide plate 21.

[0044] In some embodiments of this utility model, the first air guide plate 21 is a straight plate or an arc plate, and no further restrictions are imposed here.

[0045] In some embodiments of this utility model, such as Figure 5 As shown, in the first state, the angle between the central axis of each air diffuser 211 and the horizontal plane is α1, 30° < α1 < 100°. Thus, even if the first air guide plate 21 is provided with air diffuser 211, in the first state, the airflow direction through the air diffuser 211 is abruptly turned, and the air will not flow through the air diffuser 211 to the front air outlet grille 12.

[0046] Specifically, when the air inside the housing 100 flows towards the front air outlet grille 12, the air needs to be discharged forward along the horizontal plane, so that 30° < α1 < 100°. This can control the air flowing through the air diffuser 211 at this time to change direction abruptly, so that the first air guide plate 21 does not leak air.

[0047] When the wall-mounted indoor unit 1 heats a designated area, the first air guide plate 21 is in the first state. At this time, the air inside the casing 100 can flow along the first air guide plate 21 to the bottom air outlet 11, so that the air can be discharged through the bottom air outlet 11.

[0048] The setting of 30° < α1 < 100° effectively prevents hot air from flowing through the air vents 211 to the front air outlet grille 12, thereby ensuring that hot air flows out from the bottom air outlet 11. This improves the uniformity and efficiency of the wall-mounted indoor unit 1 in heating the designated area, thus enhancing user comfort.

[0049] Specifically, if α1 is too small, less than 30°, the air inside the casing 100 will easily flow through the air diffuser 211 to the front air outlet grille 12, which will easily cause hot air to leak out from the front air outlet grille 12. If α1 is too large, the air diffuser 211 will be difficult to form, the cost will be high, and it will easily affect the strength of the first air guide plate 21.

[0050] In some embodiments of this utility model, such as Figure 4 , Figure 5As shown, in the first state, the lower end of the first air guide plate 21 is located inside the bottom air outlet 11 so that the lower end of the first air guide plate 21 can separate the front air outlet grille 12, thereby achieving full shielding of the front air outlet grille 12 and preventing hot air from flowing out from the front air outlet grille 12, which would affect the heating effect of the hot air.

[0051] In some embodiments of this utility model, such as Figure 4 , Figure 5 As shown, in the longitudinal section of the first air guide plate 21, the line connecting the two ends of the first air guide plate 21 is the first connecting line K1, and the angle between the central axis of each air diffuser hole 211 and the first connecting line K1 is α2, where 30° < α2 < 90°. Thus, in the first state, when the first air guide plate 21 blocks the front air outlet grille 12, even if the first air guide plate 21 is provided with air diffuser holes 211, air will not flow to the front air outlet grille 12 through the air diffuser holes 211.

[0052] If α2 is too small, the air diffuser 211 will be difficult to form, resulting in higher costs and potentially affecting the strength of the first air guide plate 21. If α2 is too large, the air inside the casing 100 will easily flow through the air diffuser 211 to the front air outlet grille 12, which could lead to hot air leaking out from the front air outlet grille 12.

[0053] Specifically, in the first state, when the wall-mounted indoor unit 1 heats the designated area, the air inside the casing 100 can flow along the first air guide plate 21 to the bottom air outlet 11, so that the air can be discharged through the bottom air outlet 11.

[0054] Specifically, 30° < α2 < 90° is set so that when air flows along the first air guide plate 21, the airflow direction through the air diffuser hole 211 changes abruptly and bends, and the air will not flow through the air diffuser hole 211 to the front air outlet grille 12, thereby preventing air from flowing through the air diffuser hole 211 to the front air outlet grille 12.

[0055] In some embodiments of this utility model, such as Figure 10 , Figure 11 As shown, each air diffuser 211 is formed into a rectangle, which facilitates the regular distribution of a large number of air diffusers 211 on the first air guide plate 21, so that the air can be refined by using multiple air diffusers 211. In the second state, when the first air guide plate 21 blocks the bottom air outlet 11 and the air flows out through multiple air diffusers 211, the air can be delivered evenly without feeling the wind.

[0056] In addition, by providing multiple air dissipation holes 211 on the first air guide plate 21, it is easy to reduce the weight and material cost of the first air guide plate 21.

[0057] In some embodiments of this utility model, such as Figure 10 , Figure 11As shown, the shortest side of the air diffuser 211 is greater than 1.5mm to control the size of the air diffuser 211 and prevent it from being too small to allow air to escape.

[0058] like Figure 11 As shown, on the longitudinal section of the first air guide plate 21, the length of the rectangular air diffuser hole 211 is L1, the width of the rectangular air diffuser hole 211 is L2, and L1 > L2 > 1.5mm.

[0059] In some embodiments of this utility model, such as Figure 11 As shown, in the width direction of the first air guide plate 21, the first air guide plate 21 includes multiple rows of air diffuser groups 212. Each row of air diffuser groups 212 includes multiple air diffuser holes 211 spaced apart along the length direction of the first air guide plate 21. The air diffuser holes 211 of adjacent rows of air diffuser groups 212 are staggered. When air flows out through the air diffuser holes 211, the staggered air diffuser holes 211 are suitable for making the airflow through the air diffuser area more uniform.

[0060] It is understandable that the staggered arrangement of the air diffuser holes 211 of adjacent rows of air diffuser groups 212 means that the air diffuser holes 211 of adjacent rows of air diffuser groups 212 are staggered in the length direction of the first air guide plate 21. For example, the length direction of the first air guide plate 21 is arranged in the left and right direction, and the left inner wall of the air diffuser holes 211 of adjacent rows of air diffuser groups 212 is staggered in the left and right direction, or the right inner wall of the air diffuser holes 211 of adjacent rows of air diffuser groups 212 is staggered in the left and right direction. This makes it easier for multiple air diffuser holes 211 to achieve better air diffusion effect and make the air flowing through the air diffusion area more uniform.

[0061] In some embodiments of this utility model, such as Figure 7 As shown, the first air guide plate 21 has a third state. In the third state, the first air guide plate 21 rotates to divert the airflow to the front air outlet grille 12 and the bottom air outlet 11. At this time, the air inside the housing 100 can be discharged downward through the bottom air outlet 11 and discharged forward and downward through the front air outlet grille 12.

[0062] Specifically, when the wall-mounted indoor unit 1 is cooling or heating a designated area, and the first air guide plate 21 is in the third state, the air inside the casing 100 can be discharged through the bottom air outlet 11 and the front air outlet grille 12, which effectively increases the air outlet angle and range, improves the uniformity and efficiency of the wall-mounted indoor unit 1 in cooling or heating the designated area, and facilitates the improvement of user comfort.

[0063] In some embodiments of this utility model, such as Figure 4 , Figure 5As shown, the front air vent grille 12 includes a plurality of first grille bars 121 spaced apart in the vertical direction. A first air vent 122 is defined between adjacent first grille bars 121. The bottom wall of the first air vent 122 extends forward and upward at an angle, and air inside the housing 100 can flow out upward and forward at an angle along the plurality of first air vent 122.

[0064] The cold or hot air inside the casing 100 can be discharged upwards from the front air outlet grille 12, which effectively increases the air outlet angle and range of the wall-mounted indoor unit 1, improves the uniformity and efficiency of the wall-mounted indoor unit 1 in cooling or heating the designated area, and facilitates the improvement of user comfort.

[0065] In addition, the bottom wall of the first air outlet duct 122 is inclined forward and upward, so that when the air blown out by the wall-mounted indoor unit 1 is cold air to cool the designated area, the cold air can be avoided from blowing directly on the user, which can improve the user's comfort.

[0066] In some optional embodiments of this utility model, such as Figure 5 As shown, the angle between the bottom wall of the first air outlet duct 122 and the horizontal direction ranges from α3, where 0 < α3 < 30°.

[0067] Specifically, α3 is set greater than 0° to ensure that the air blown out along the first air outlet duct 122 is directed upwards, thereby preventing cold air from blowing directly onto the user and improving user comfort. α3 is set less than 30° to ensure the effectiveness of the airflow from the front air outlet grille 12, preventing the air from failing to effectively cool or heat the designated area below the wall-mounted indoor unit 1. Specifically, an excessively large α3 will cause the air blown out from the front air outlet grille 12 to blow too upwards, potentially failing to cool or heat the designated area below the wall-mounted indoor unit 1.

[0068] In some optional embodiments of this utility model, the wall-mounted indoor unit 1 further includes a first driving member, and the first air guide plate 21 has a mating part 214. The first driving member cooperates with the mating part 214 to drive the first air guide plate 21 to rotate, so that the first air guide plate 21 can rotate within the housing 100, and the first air guide plate 21 can switch between a first state, a second state and a third state, thereby changing the extension direction of the first air guide plate 21, so as to change the air flow direction within the housing 100 by using the first air guide plate 21, and guide the air to the front air outlet grille 12 and / or the bottom air outlet 11.

[0069] Specifically, by controlling the rotation angle of the first air guide plate 21, the orientation of the central axis of the air diffuser 211 can be controlled, so that the first air guide plate 21 can block the front air outlet grille 12 in the first state, and hot air will not flow from the air diffuser 211 to the front air outlet grille 12, so that the wall-mounted indoor unit 1 heats and exhausts air from the bottom air outlet 11, which greatly improves the heating effect and stratification uniformity, and makes the wall-mounted indoor unit 1 have a better heating effect on the designated area.

[0070] In some specific embodiments of this utility model, the first air guide plate 21 has rotating parts at both ends in the length direction. The rotating parts are rotatably engaged with the housing 100. The engaging part 214 is located between the two rotating parts. The rotating parts are used to support the rotation of the first air guide plate 21, so that the first air guide plate 21 can rotate stably inside the housing 100.

[0071] In some embodiments, such as Figure 10 As shown, the rotating part is a rotating shaft 216. At least one end of the first air guide plate 21 in the length direction is provided with a rotating shaft 216. The rotating shaft 216 is rotatably engaged with the housing 100 to support the rotation of the first air guide plate 21.

[0072] In some embodiments, such as Figure 10 As shown, the rotating part is a mating hole 217. At least one end of the first air guide plate 21 in the length direction is provided with a mating hole 217. The mating hole 217 is rotatably mated with the housing 100 to support the rotation of the first air guide plate 21.

[0073] In some examples, three connecting lugs 215 are provided on one side of the first air guide plate 21 in the thickness direction. The three connecting lugs 215 are arranged along the length direction of the first air guide plate 21. Rotating parts are provided on the connecting lugs 215 on both sides of the length direction of the first air guide plate 21, one of which is a rotating shaft 216 and the other is a mating hole 217. A mating part 214 is provided on the connecting lug 215 located in the middle of the length direction of the first air guide plate 21. The mating part 214 cooperates with the first driving member so that the first driving member can drive the first air guide plate 21 to rotate from the middle of the length direction of the first air guide plate 21. The rotating parts at both ends of the length direction of the first air guide plate 21 rotate and cooperate with the housing 100 to support the stable rotation of the first air guide plate 21.

[0074] Furthermore, the connecting lug 215 with the mating part 214 is located in the middle of the width direction of the first air guide plate 21.

[0075] In some embodiments of this utility model, such as Figure 7 , Figure 8 As shown, the wall-mounted indoor unit 1 also includes a second air guide plate 22, which is used to open or close the bottom air outlet.

[0076] Specifically, when air needs to be vented from the bottom air outlet 11, the second air guide plate 22 opens the bottom air outlet 11, and when air does not need to be vented from the bottom air outlet 11, the second air guide plate 22 closes the bottom air outlet 11. This helps to reduce the possibility of indoor dust entering the bottom air outlet 11 and prevents the wall-mounted indoor unit 1 from blowing out air with excessive dust content, which could affect the respiratory health of users.

[0077] In some embodiments, such as Figure 9 As shown, when the second air guide plate 22 closes the bottom air outlet 11, when air needs to be discharged from the front air outlet grille 12, the first air guide plate 21 rotates to the third state to avoid the airflow from the front air outlet grille 12, so that the air can flow out from the front air outlet grille 12 and avoid cold air blowing directly to the user.

[0078] In addition, the first air guide plate 21 can swing to sweep the air, so that when the airflow flows towards the front air outlet grille 12, it can effectively increase the air outlet angle and air outlet range, thereby improving the comfort of cooling or heating.

[0079] In some specific embodiments of this utility model, such as Figure 2 As shown, the wall-mounted indoor unit 1 also includes a second driving member and a first swing arm 51. One end of the first swing arm 51 cooperates with the second driving member, and the other end cooperates with the second air guide plate 22. The second driving member is used to drive the first swing arm 51 to swing, so that the first swing arm 51 drives the second air guide plate 22 to move.

[0080] Specifically, when the second driving member drives the first swing arm 51 to rotate, the first swing arm 51 drives the second air guide plate 22 to swing, so that the second air guide plate 22 can swing between the position of closing the bottom air outlet 11 and the position of opening the bottom air outlet 11.

[0081] Since the first swing rod 51 is suitable for driving the second air guide plate 22 to swing, the swing center axis of the second air guide plate 22 coincides with the rotation center axis of the first swing rod 51. In this way, by controlling the distance between the rotation center axis of the first swing rod 51 and the second air guide plate 22, the position of the swing center axis of the second air guide plate 22 can be flexibly adjusted. For example, by making the distance between the rotation center axis of the second air guide plate 22 and the first swing rod 51 larger, the swing radius of the second air guide plate 22 can be set to be larger, and thus the swing range of the second air guide plate 22 can be set to be larger, so that the second air guide plate 22 can swing to a position outside the casing 100 and at least partially offset from the bottom air outlet 11. In this way, when the second air guide plate 22 opens the bottom air outlet 11, the obstruction area of ​​the second air guide plate 22 on the bottom air outlet 11 can be reduced, the wind resistance at the bottom air outlet 11 can be reduced, and the air volume of the wall-mounted indoor unit 1 at the bottom air outlet 11 can be increased, so as to achieve a large air volume of air output from the wall-mounted indoor unit 1 at the bottom air outlet 11.

[0082] In some embodiments, the wall-mounted indoor unit 1 further includes a second swing arm 52. One end of the second swing arm 52 is rotatably connected to the housing 100, and the other end of the second swing arm 52 is rotatably connected to the second air guide plate 22. The first swing arm 51 and the second swing arm 52 are arranged at intervals along the length direction of the second air guide plate 22. The second swing arm 52 is used to support the swing of the second air guide plate 22, so that the second air guide plate 22 can swing stably to open or close the bottom air outlet 11.

[0083] Specifically, when the second driving member drives the first swing arm 51 to rotate, the first swing arm 51 is adapted to drive the second air guide plate 22 to swing. At this time, the second air guide plate 22 rotates relative to the second swing arm 52 and drives the second swing arm 52 to rotate relative to the housing 100, so that the second swing arm 52 adapts to the movement trajectory of the second air guide plate 22 and plays a role in stabilizing and supporting the second air guide plate 22.

[0084] In some embodiments, the second driving component includes a drive motor and a transmission assembly. The transmission assembly includes multiple transmission gears. The motor shaft of the drive motor is adapted to drive the transmission gears to rotate. The transmission assembly includes an output shaft. The first swing arm 51 has a connecting hole. The output shaft is engaged with the connecting hole so that when the transmission gears rotate, the first swing arm 51 can be driven to rotate, thereby driving the second air guide plate 22 to swing, so that the second air guide plate 22 can open or close the bottom air outlet 11.

[0085] In some examples, the output shaft has an elastic arm with a mating protrusion and a mating groove on the wall of the connecting hole. When the output shaft is inserted into the connecting hole, the elastic arm deforms under elastic action so that the part of the elastic arm with the mating protrusion can smoothly enter the connecting hole. When the mating protrusion moves to the position corresponding to the mating groove, the elastic arm returns to its original shape, and the mating protrusion engages with the mating groove, thereby realizing the engagement of the output shaft and the first rocker arm 51. When the output shaft of the drive motor rotates, the drive motor drives the output shaft to rotate through the transmission assembly, and the output shaft drives the first rocker arm 51 to rotate.

[0086] In some specific embodiments of this utility model, the second air guide plate 22 has a double-layer hollow structure, which facilitates the second air guide plate 22 to have better strength and thermal insulation. Furthermore, when the second air guide plate 22 closes the bottom air outlet 11, the possibility of air leakage at the bottom air outlet 11 is reduced.

[0087] In other embodiments, the second air guide plate 22 is a single-layer structure, which makes it easier to reduce the weight of the second air guide plate 22, thereby reducing the load on the second drive component.

[0088] In some embodiments of this utility model, such as Figures 4-9As shown, the wall-mounted indoor unit 1 also includes an indoor heat exchanger 81 and a fan wheel 82. The fan wheel 82 is located inside the casing 100 and is used to drive air to flow from the air inlet of the wall-mounted indoor unit 1 to the bottom air outlet 11.

[0089] The indoor heat exchanger 81 is located between the impeller 82 and the air inlet of the wall-mounted indoor unit 1. The indoor heat exchanger 81 is used to cool or heat the air entering the casing 100 from the air inlet, thereby generating cold or hot air. When the impeller 82 rotates, it drives the cold or hot air to flow from the bottom air outlet 11 or the front air outlet grille 12 to the designated area, thereby achieving cooling or heating of the designated area.

[0090] In some embodiments of this utility model, such as Figure 6 , Figure 7 As shown, a swing blade 25 is also provided between the impeller 82 and the bottom air outlet 11. The swing blade 25 is adapted to swing to change the airflow direction at the bottom air outlet 11, thereby changing the air outlet direction of the wall-mounted indoor unit 1. For example, the swing blade 25 is adapted to swing to the left or right so that the wall-mounted indoor unit 1 can outlet air to the left or right.

[0091] In some specific embodiments of this utility model, the housing 100 has a front air outlet grille 12 and a bottom air outlet 11.

[0092] The first air guide plate 21 is rotatably disposed within the housing 100. In a first state, the first air guide plate 21 rotates to block the front air outlet grille 12 to prevent airflow from reaching the front air outlet grille 12; in a second state, the first air guide plate 21 rotates to block the bottom air outlet 11; in a third state, the first air guide plate 21 rotates to divert airflow to the front air outlet grille 12 and the bottom air outlet 11. The second air guide plate 22 is rotatably connected to the housing 100 and is used to open or close the bottom air outlet 11.

[0093] The wall-mounted indoor unit 1 also includes a first driving component and a second driving component. The first driving component is used to drive the first air guide plate 21 to rotate, so that the first air guide plate 21 switches between a first state, a second state, and a third state. The second driving component is used to drive the second air guide plate 22 to rotate, so that the second air guide plate 22 opens or closes the bottom air outlet 11.

[0094] The first and second driving components are independent driving components, which can independently control one or all of the air outlets 12 and 11 at the bottom, thereby facilitating the fulfillment of different air outlet requirements of the wall-mounted indoor unit 1. This allows the wall-mounted indoor unit to have more air outlet modes to adapt to diverse scenarios and improve user comfort.

[0095] It should be mentioned that the extension direction of the central axis of each air diffuser 211 intersects the thickness direction of the first air guide plate 21. By controlling the position of the first air guide plate 21 and the orientation of the air diffuser 211, the airflow through the air diffuser 211 can be controlled to be either a downwind or a sudden turn. This ensures that when the first air guide plate 21 is in the first state, the heating airflow does not pass through the air diffuser 211; when the first air guide plate 21 is in the second state, the cooling airflow passes through the air diffuser 211, so that the first air guide plate 21 can fully match the needs of each mode, such as satisfying the heating, cooling, all-around airflow, and anti-blowing modes of the wall-mounted indoor unit 1.

[0096] In some embodiments, such as Figure 4 As shown, the second air guide plate 22 opens the bottom air outlet 11, the first air guide plate 21 is in the first state, the first air guide plate 21 blocks the front air outlet grille 12 to guide the airflow to the bottom air outlet 11, so as to meet the heating mode of the wall-mounted indoor space.

[0097] Specifically, in such as Figure 4 In the indicated state, the wall-mounted indoor unit 1 blows out hot air to heat the designated area. At this time, the first air guide plate 21 blocks the front air outlet grille 12, causing the wall-mounted indoor unit 1 to expel air through the bottom air outlet 11. This allows the wall-mounted indoor unit 1 to expel air downwards through the bottom air outlet 11. Since hot air has a lower density and tends to rise, the wall-mounted indoor unit 1 expels air downwards through the bottom air outlet 11, effectively achieving the effect of the heating airflow blowing downwards towards the bottom air outlet 11. This solves the problem of poor downward airflow effect in traditional wall-mounted heating systems, improving the foot warming effect, increasing the temperature rise rate, and improving the uniformity of heating stratification.

[0098] In some embodiments, such as Figure 6 As shown, the second air guide plate 22 opens the bottom air outlet 11, and the first air guide plate 21 is in the second state. The first air guide plate 21 blocks the bottom air outlet 11. At this time, the wall-mounted indoor unit 1 can vent air through the front air outlet grille 12 and the air vents 211 on the first air guide plate 21 to meet the anti-direct-blow cooling mode of the wall-mounted indoor unit.

[0099] Specifically, in such as Figure 6 In the indicated state, the wall-mounted indoor unit 1 blows out cold air to cool the designated area. The wall-mounted indoor unit 1 can blow air forward through the front air outlet grille 12 and achieve imperceptible airflow through the air vents 211. This ensures the airflow efficiency of the wall-mounted indoor unit 1 while also preventing cold air from blowing directly on the user, thus improving the user's comfort.

[0100] In some embodiments, such as Figure 7As shown, the second air guide plate 22 opens the bottom air outlet 11, and the first air guide plate 21 is in the third state. At this time, the wall-mounted indoor unit 1 can exhaust air through the front air outlet grille 12 and the bottom air outlet 11 to meet the full air outlet mode of the wall-mounted indoor unit 1.

[0101] Specifically, in Figure 7 In this state, the wall-mounted indoor unit 11 can achieve full air output, and the wall-mounted indoor unit 11 has a large air output volume, which improves the efficiency of the wall-mounted indoor unit 11 in cooling or heating a designated area.

[0102] In addition, the first air guide plate 21 can swing to sweep the air so that the airflow can be simultaneously discharged from the forward air outlet grille 12 and the bottom air outlet 11, which effectively increases the air outlet angle and air outlet range, and improves the comfort of cooling or heating.

[0103] In some embodiments, such as Figures 8-10 As shown, the second air guide plate 22 closes the bottom air outlet 11, and the first air guide plate 21 is in the third state to direct the airflow to the front air outlet grille 12 to meet the cooling mode of the wall-mounted indoor unit 1.

[0104] Specifically, in such as Figures 8-10 In the indicated state, the wall-mounted indoor unit 1 blows out cold air to cool the designated area. The first air guide plate 21 guides the air to the front air outlet grille 12. The wall-mounted indoor unit 1 can blow air forward through the front air outlet grille 12, which can avoid the cold air blowing directly on the user and improve the user's comfort.

[0105] In summary, by setting multiple air vents 211 on the first air guide plate 21, the first air guide plate 21 can switch between the first state, the second state and the third state, which facilitates meeting the various air outlet requirements of the wall-mounted indoor unit 1.
