Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a wall-mounted air conditioning indoor unit with symmetrical air guide vanes. Background Technology

[0002] With the improvement of people's living standards, air conditioners have become widely used electrical appliances in homes and offices. As the part of the air conditioning system that directly interacts with users, the performance and air delivery effect of the indoor unit are crucial to the user experience. To achieve adjustment of the airflow direction, a rotatable air guide vane structure is usually configured.

[0003] Currently, in existing technologies, traditional horizontal air guide vanes mostly adopt a single flat plate structure, but this has problems such as a limited air delivery mode and a limited air delivery range. Furthermore, the air guide vane is usually positioned at the air outlet, and its rotation axis is located at the bottom of both the vane and the air outlet. This limits the vane's rotation angle, thus restricting the diversity of air delivery modes available in the air conditioner. Utility Model Content

[0004] One objective of this invention is to provide a wall-mounted air conditioner indoor unit with symmetrical air guide vanes that can overcome at least one of the technical defects in the prior art.

[0005] A further objective of this invention is to ensure the rotational flexibility of the air guide vanes in order to improve the air delivery diversity of the wall-mounted air conditioner indoor unit.

[0006] Specifically, this utility model provides a wall-mounted air conditioner indoor unit comprising:

[0007] The housing has a horizontally extending air outlet at its lower front part;

[0008] An air guide vane is rotatably mounted on the outer side of the air outlet, with its axis of rotation extending along the length of the air outlet. The air guide vane includes a first wing plate and a second wing plate, which extend radially from the axis of rotation and are positioned at a predetermined angle.

[0009] The preset included angle range is greater than or equal to 90° and less than 180°; and,

[0010] The first and second wing plates have the same width in the direction away from the axis of rotation.

[0011] Furthermore, the axial distance between the rotation axis and the bottom outer wall of the housing in the vertical direction is greater than or equal to 10 mm and less than or equal to 60 mm.

[0012] Furthermore, the width of the first wingplate is greater than or equal to the axial distance and less than or equal to twice the axial distance.

[0013] Furthermore, the housing is equipped with an air outlet duct extending downwards and forwards, the outlet end of which connects to an air outlet; and,

[0014] The width of the first wing plate is greater than 20mm and less than the length of the duct extension line, which is a straight line extending forward and downward from the bottom of the air outlet end along the bottom surface of the air outlet duct to a point flush with the top of the air outlet; or,

[0015] The width of the first wing plate is greater than 20mm and less than two-thirds of the length of the duct extension line. The duct extension line is a straight line extending forward and downward from the bottom of the air outlet end along the bottom surface of the air outlet duct to a point flush with the top of the air outlet.

[0016] Furthermore, the indoor unit of a wall-mounted air conditioner also includes:

[0017] An air guide plate, rotatably mounted at the air outlet, is used to close and open the air outlet. Its center of rotation is arranged laterally and located at the midpoint of the air outlet in the vertical direction. Air guide vanes are located below the air guide plate.

[0018] The housing contains an air outlet duct extending downwards and forwards, with the outlet end of the duct connected to an air outlet; and...

[0019] The wind deflector is constructed with an inner side forming a predetermined angle and an outer side opposite to the inner side; and,

[0020] The end of the first wingplate furthest from the axis of rotation is the first air intake end, and the end of the second wingplate furthest from the axis of rotation is the second air intake end.

[0021] Furthermore, the wall-mounted air conditioner indoor unit has a maximum air supply mode. In this mode, the air guide vanes are arranged along the front-to-back direction, with the inner side of the vanes facing upwards.

[0022] In maximum air supply mode, the outer side of the air guide vane faces the air outlet, the first air intake end is opposite to and close to the bottom of the air outlet, the first wing plate is arranged along the bottom surface of the air outlet duct, and the second air intake end is arranged facing forward and downward.

[0023] Furthermore, in the maximum air supply mode, the side of the first wing facing the air outlet duct is flush with the bottom surface of the air outlet duct; and or,

[0024] In maximum airflow mode, the side of the first wing facing the air outlet duct is positioned lower than the bottom surface of the air outlet duct; and or,

[0025] In the maximum air supply mode, the side of the first wing facing the air outlet duct is set lower than the bottom surface of the air outlet duct, and the vertical distance between the side of the first wing facing the air outlet duct and the bottom surface of the air outlet duct is less than or equal to 5mm.

[0026] Furthermore, in the maximum air supply mode, with the bottom of the air outlet end of the air outlet duct as the apex, the angle between the first wing plate and the extension line of the air outlet duct is ±5°, wherein the extension line of the air outlet duct is a straight line extending forward and downward from the bottom of the air outlet end along the bottom surface of the air outlet duct to a point level with the top of the air outlet.

[0027] Furthermore, in the maximum air supply mode, the distance between the bottom of the first air intake end and the bottom of the air outlet is greater than or equal to 3mm and less than or equal to 5mm.

[0028] Furthermore, both the first and second wing plates are curved plates, with the middle portion of the first wing plate concave and curved away from the second wing plate, and the middle portion of the second wing plate also concave and curved away from the first wing plate; and...

[0030] This utility model discloses a wall-mounted air conditioner indoor unit. Because it places the air guide vanes outside the air outlet, and the first and second vanes of the air guide vanes have the same width, and with sufficient space between the air guide vanes and the bottom of the air outlet for either the first or second vane to pass through, the air guide vanes can rotate 360° below the air outlet without interference to their rotation. Therefore, this utility model's wall-mounted air conditioner indoor unit ensures the flexibility of the air guide vanes' rotation and improves the versatility of its airflow.

[0031] Furthermore, in the wall-mounted air conditioner indoor unit of this utility model, the preset angle can be set to a range greater than or equal to 90° and less than 180°, so that the air guide vanes can change the airflow direction in a V-shape, ensuring the diversity of the airflow direction guided by the air guide vanes, while avoiding excessive obstruction of the airflow due to an excessively large preset angle, thus ensuring the fluidity of the airflow.

[0052] The following is combined with Figures 1 to 12 This embodiment describes the wall-mounted air conditioner indoor unit. Wherein, Figures 8 to 12 The black arrows indicate the flow path and direction of cooling airflow, heating airflow, or mixed airflow, while the blank arrows indicate the flow path and direction of ambient airflow in the indoor space.

[0053] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the wall-mounted air conditioner indoor unit includes a housing 100 and an air guide vane 200.

[0054] The housing 100 has a horizontally extending air outlet 120 at its lower front part.

[0055] The air guide 200 is rotatably disposed on the outside of the air outlet 120. The rotation axis 210 of the air guide 200 extends along the length direction of the air outlet 120. The air guide 200 includes a first wing plate 220 and a second wing plate 230. The first wing plate 220 and the second wing plate 230 extend radially from the rotation axis 210 and are set at a preset included angle α.

[0056] The preset included angle α is greater than or equal to 90° and less than 180°.

[0057] The first wing plate 220 and the second wing plate 230 have the same wing plate width K in the direction away from the rotation axis 210.

[0058] In this embodiment of the wall-mounted air conditioner indoor unit, the air guide vane 200 is positioned outside the air outlet 120, and the width K of the first wing plate 220 and the second wing plate 230 of the air guide vane 200 is set to the same width. Therefore, with sufficient space between the air guide vane 200 and the bottom of the air outlet 120 for either the first wing plate 220 or the second wing plate 230 to pass through, the air guide vane 200 can rotate 360° below the air outlet 120 without interference to the rotation of either the first wing plate 220 or the second wing plate 230. Thus, this embodiment of the wall-mounted air conditioner indoor unit ensures the rotational flexibility of the air guide vane 200 and improves the versatility of the air delivery.

[0059] Furthermore, in this embodiment, the preset included angle α of the wall-mounted air conditioner indoor unit can be set to a range greater than or equal to 90° and less than 180°. This allows the air guide vane 200 to change the airflow direction in a V-shape, ensuring the diversity of airflow direction guidance provided by the air guide vane 200. Simultaneously, it avoids excessive obstruction of the airflow due to an excessively large preset included angle α, ensuring airflow fluidity. Moreover, within the range specified in this embodiment, the preset included angle α allows the air guide vane 200 to simultaneously accommodate both upward blowing of cooling air and downward blowing of heating air.

[0060] In this embodiment, the wall-mounted air conditioner indoor unit may also include a drive device (not shown), which is drivably connected to one or both ends of the air guide vane 200 in the left-right direction to drive the rotation of the air guide vane 200.

[0061] In this embodiment, the driving device may include a drive motor (not shown) and a drive gear set (not shown), the drive gear set being connected between the motor shaft of the drive motor and the rotation axis 210 of the wind vane 200.

[0062] Reference Figure 1 and Figure 2 In this embodiment, a left mounting bracket 510 and a right mounting bracket 520 extending to the lower part of the housing 100 can be respectively provided on the left and right sides of the housing 100. The air guide wing 200 is rotatably mounted between the left mounting bracket 510 and the right mounting bracket 520. Furthermore, the air guide wing 200 can be rotatably disposed on the outside of the air outlet 120. And the driving device can be disposed on the left mounting bracket 510 and / or the right mounting bracket 520.

[0063] Reference Figure 1 and Figure 2In this embodiment, the left mounting bracket 510 may include a left vertical plate 511 and a left horizontal plate 512. The left vertical plate 511 is arranged vertically, and its top end is connected to the left side wall of the housing 100. The left horizontal plate 512 is arranged horizontally, and its left end is connected to the bottom end of the vertical plate. The right mounting bracket 520 may include a right vertical plate 521 and a right horizontal plate 522. The right vertical plate 521 is arranged vertically, and its top end is connected to the right side wall of the housing 100. The right horizontal plate 522 is arranged horizontally, and its right end is connected to the bottom end of the vertical plate. The left and right ends of the air guide wing 200 are rotatably connected to the right end of the left horizontal plate 512 and the left end of the right horizontal plate 522, respectively. Therefore, the air guide wing 200 can be rotatably disposed on the outside of the air outlet 120.

[0064] Reference Figure 4 In this embodiment, the axial distance H between the rotation axis 210 and the bottom outer wall of the housing 100 in the vertical direction is greater than or equal to 10 mm and less than or equal to 60 mm.

[0065] Understandably, setting the axial distance H within the range of 10mm or greater and 60mm or less provides sufficient space for the rotation of the air guide vane 200, while ensuring the air guide vane 200 guides the airflow exiting the air outlet 120. Furthermore, when the wall-mounted air conditioner indoor unit operates in the cooling top-blowing mode and cooling front-blowing mode as described in the following embodiments, the aforementioned range of the axial distance H effectively ensures the appropriateness of the negative pressure intensity formed at the preset included angle α or above the first wing plate 220, thereby ensuring the comfort of the cooling airflow temperature and guaranteeing a positive user experience.

[0066] Reference Figure 3 and Figure 4 In this embodiment, the wing width K of the first wing plate 220 is greater than or equal to the axial distance H and less than or equal to twice the axial distance H.

[0067] It is understandable that setting the wing width K of the first wing plate 220 to be greater than or equal to the axial distance H and less than or equal to twice the axial distance H ensures that the guide vane 200 guides the airflow exiting the air outlet 120. Simultaneously, within this range, the wing width K of the first wing plate 220 can prevent airflow from being blown outwards in the heating front-blowing mode and heating rear-blowing mode of the following embodiments (refer to...). Figure 11 and Figure 12The air guide 200 directs all the heating airflow through the space between itself and the bottom of the air outlet 120 to the wall, while causing some of the heating airflow to flow out of the air outlet 120 through the space between the air guide 200 and the air guide plate 600. This ensures the operation of the heating front-blowing mode and the heating rear-blowing mode, and ensures the air outlet range of the wall-mounted air conditioner indoor unit when it is operating in the heating front-blowing mode and the heating rear-blowing mode.

[0068] Reference Figure 4 In this embodiment, an air outlet duct 110 extending in a forward and downward direction is provided inside the housing 100, and the air outlet end of the air outlet duct 110 is connected to the air outlet 120.

[0069] Reference Figure 4 In this embodiment, the top of the housing 100 is provided with an air inlet 130 that connects to the air outlet duct 110. Furthermore, the wall-mounted air conditioner indoor unit may also include an indoor heat exchanger 410 and an indoor fan 420 disposed within the air outlet duct 110. The indoor heat exchanger 410 functions as either an evaporator or a condenser. Under the action of the indoor fan 420, the airflow entering the air inlet 130 exchanges heat with the indoor heat exchanger 410 to obtain a cooling or heating airflow. The cooling or heating airflow is then guided towards the air outlet 120 by the air outlet duct 110.

[0070] Reference Figure 4 In this embodiment, the air duct extension line 111 is a straight line extending forward and downward from the bottom of the air outlet end along the bottom surface of the air outlet duct 110 to a position flush with the top of the air outlet 120.

[0071] Reference Figure 3 and Figure 4 In this embodiment, the wing width K of the first wing plate 220 is greater than 20 mm and less than the length L of the duct extension line 111.

[0072] It is understandable that setting the wing width K of the first wing plate 220 to be greater than 20mm and less than the length L of the air duct extension line 111 can ensure the guiding effect of the air guide wing 200 on the airflow flowing out of the air outlet 120, while avoiding interference from other components of the wall-mounted air conditioner indoor unit during the rotation of the air guide wing 200.

[0073] Reference Figure 3 and Figure 4 In this embodiment, the wing width K of the first wing plate 220 is greater than 20 mm and less than two-thirds of the length L of the duct extension line 111.

[0074] It is understandable that setting the wing width K of the first wing plate 220 to be greater than 20mm and less than two-thirds of the length L of the duct extension line 111 ensures the guiding effect of the air guide wing 200 on the airflow and prevents the rotation of the air guide wing 200 from being interfered with by other components of the wall-mounted air conditioner indoor unit. At the same time, within the range specified in this embodiment, the rotational coordination between the air guide wing 200 and the air guide plate 600 is optimal, which can accommodate both the cooling and heating modes described in the following embodiments.

[0075] Reference Figure 3 and Figure 4 In this embodiment, the wall-mounted air conditioner indoor unit also includes an air guide plate 600.

[0076] The air guide plate 600 is rotatably disposed at the air outlet 120. The air guide plate 600 is used to close and open the air outlet 120. Its rotation center 610 is arranged in the horizontal direction and is located in the middle of the air outlet 120 in the vertical direction. The air guide wing 200 is located below the air guide plate 600.

[0077] It is understood that the air guide vane 200 in this embodiment can cooperate with the air guide plate 600 to enable the wall-mounted air conditioner indoor unit to achieve more air supply modes, so as to further improve the diversity of air supply modes of the wall-mounted air conditioner indoor unit and improve the user experience.

[0078] Reference Figure 3 In this embodiment, a clearance groove 112 extending laterally is provided at the top of the air outlet duct 110 relative to the top of the air plate 620. The clearance groove 112 is used to allow the air guide plate 600 to rotate. The top of the air plate 620 is the end of the air guide plate 600 adjacent to the top of the air outlet 120 when the air outlet 120 is closed.

[0079] Understandably, the design of the clearance slot 112 ensures the rotatability of the air guide plate 600. Furthermore, in some air supply modes of the wall-mounted air conditioner indoor unit (such as maximum air supply mode, cooling top-blowing mode, cooling front-blowing mode, cooling bottom-blowing mode, heating bottom-front-blowing mode, and heating bottom-rear-blowing mode), the airflow in the air outlet duct 110 can flow out of the air outlet 120 from the clearance slot 112 and flow in the target direction, ensuring the air supply range of the wall-mounted air conditioner indoor unit.

[0080] Reference Figure 3 In this embodiment, the wind deflector 200 is configured to have an inner side 240 forming a preset included angle α and an outer side 250 opposite to the inner side 240.

[0081] Reference Figure 3In this embodiment, the end of the first wing plate 220 away from the rotation axis 210 is the first air-guiding end 221, and the end of the second wing plate 230 away from the rotation axis 210 is the second air-guiding end 231.

[0082] Reference Figure 4 In this embodiment, the wall-mounted air conditioner indoor unit operates in a maximum air supply mode. In the maximum air supply mode, the air guide plate 600 is arranged in the front-to-back direction, and the inner side of the air guide plate 600 is set upward.

[0083] In the maximum air supply mode, the outer side 250 of the air guide 200 is set towards the air outlet 120, the first air intake end 221 is opposite to and close to the bottom end of the air outlet 120, the first wing plate 220 is arranged along the bottom surface of the air outlet duct 110, and the second air intake end 231 is set forward and downward.

[0084] Understandably, in maximum airflow mode, the obstruction effect of the air guide plate 600 and air guide wing 200 on the airflow exiting the air outlet 120 is minimal. Furthermore, the first wing plate 220 can extend the bottom surface of the air outlet duct 110. Therefore, in maximum airflow mode, the wall-mounted air conditioner indoor unit can have a larger airflow volume and a longer airflow distance, improving the cooling, heating, or airflow effect of the wall-mounted air conditioner indoor unit and ensuring the user experience. Moreover, experiments have shown that in maximum airflow mode, compared to when the air guide plate 600 is not installed and is arranged in the front-to-back direction, with the inner side of the air guide plate 600 facing upwards, the airflow velocity can be increased by 20-30 m / s². 3 / h, the air volume can be increased by about 4%.

[0085] In this embodiment, in the maximum air supply mode, the side of the first wing plate 220 facing the air outlet duct 110 is flush with the bottom surface of the air outlet duct 110 to ensure the fluidity of airflow from the air outlet duct 110 to the indoor space.

[0086] Reference Figure 4 In this embodiment, under maximum airflow mode, the side of the first wing 220 facing the air outlet duct 110 is set lower than the bottom surface of the air outlet duct 110 to avoid the first wing 220 potentially obstructing the airflow and to ensure the smooth flow of the airflow. Furthermore, compared to setting the side of the first wing 220 facing the air outlet duct 110 flush with the bottom surface of the air outlet duct 110, the airflow in this embodiment has a larger outlet range.

[0087] Reference Figure 5In this embodiment, in the maximum air supply mode, the side of the first wing plate 220 facing the air outlet duct 110 is set lower than the bottom surface of the air outlet duct 110, and the distance F between the side of the first wing plate 220 facing the air outlet duct 110 and the bottom surface of the air outlet duct 110 in the vertical direction is less than or equal to 5mm.

[0088] It is understandable that setting the side of the first wing plate 220 facing the air outlet duct 110 lower than the bottom surface of the air outlet duct 110, and setting the vertical distance F between the side of the first wing plate 220 facing the air outlet duct 110 and the bottom surface of the air outlet duct 110 to be less than or equal to 5mm, can ensure the fluidity of the air outlet and a larger air outlet range, while also ensuring the extension effect of the first wing plate 220 on the bottom surface of the air outlet duct 110, preventing the guiding effect of the first wing plate 220 on the air outlet airflow from failing, and ensuring the air delivery distance of the air outlet airflow.

[0089] Reference Figure 6 In this embodiment, under the maximum air supply mode, with the bottom of the air outlet end of the air outlet duct 110 as the vertex, the included angle c between the first wing plate 220 and the extension line 111 of the air duct is ±5°.

[0090] Understandably, in the maximum air supply mode, the angle c between the first vane 220 and the extension line 111 of the air duct is set to ±5° to ensure the guiding effect of the first vane 220 on the airflow, while avoiding the first vane 220 from obstructing or excessively obstructing the flow of the airflow.

[0091] Reference Figure 4 In this embodiment, under the maximum air supply mode, the distance P between the bottom end of the first air intake end 221 and the air outlet 120 is greater than or equal to 3mm and less than or equal to 5mm.

[0092] Understandably, in the maximum air supply mode, the distance P between the bottom of the first air intake end 221 and the air outlet 120 is set to be greater than or equal to 3mm and less than or equal to 5mm. This is to prevent airflow from possibly flowing out between the bottom of the first air intake end 221 and the air outlet 120 in the maximum air supply mode, thus ensuring the pressure within the air outlet duct 110. At the same time, when the indoor unit of the wall-mounted air conditioner switches between different air supply modes, it is to prevent the bottom of the air outlet 120 from interfering with the air guide vane 200, thus ensuring the rotatability of the air guide vane 200.

[0093] Reference Figure 4 In this embodiment, the housing 100 includes a lower volute 140 for forming the air outlet end of the air outlet duct 110. In the maximum air supply mode, the first air intake end 221 is positioned opposite and close to the lower volute 140. Furthermore, the distance between the first air intake end 221 and the lower volute 140 can also be set to 3mm to 5mm.

[0094] Reference Figure 7 In this embodiment, both the first wing plate 220 and the second wing plate 230 are curved plates, and the middle part of the first wing plate 220 is concave and bent away from the second wing plate 230, and the middle part of the second wing plate 230 is concave and bent away from the first wing plate 220. In the maximum air supply mode, the side of the first wing plate 220 facing the air outlet duct 110 is tangent to the duct extension line 111, wherein the duct extension line 111 is a straight line extending forward and downward from the bottom of the air outlet end along the bottom surface of the air outlet duct 110 to a position flush with the top of the air outlet 120.

[0095] It is understandable that both the first wing plate 220 and the second wing plate 230 are curved plates. Therefore, both the inner surface 240 and the outer surface 250 of the first wing plate 220 (or the second wing plate 230) can be curved to further ensure the fluidity of the airflow passing over the guide vane 200 and further reduce airflow loss. Furthermore, in the maximum airflow mode, the side of the first wing plate 220 facing the outlet duct 110 is tangent to the duct extension line 111, ensuring the fluidity of the outlet airflow as it flows from the bottom of the outlet duct 110 towards the first wing plate 220, thus guaranteeing the flow rate of the outlet airflow.

[0096] Reference Figure 8 In this embodiment, the indoor unit of the wall-mounted air conditioner operates in a cooling upward blowing mode. In the cooling upward blowing mode, the air guide plate 600 is arranged in the front-to-back direction, and the inner side of the air guide plate 600 is set upward.

[0097] In the cooling upward blowing mode, the inner side 240 of the air guide wing 200 is set towards the air outlet 120, and the second air duct end 231 is set towards the rear. An air duct gap 300 is provided between the second wing plate 230 and the bottom outer surface of the housing 100. The air duct gap 300 is used to guide the ambient airflow at the bottom of the housing 100 to a preset angle a and mix it with the cooling airflow when the cooling airflow flows out of the air outlet 120. The first air duct end 221 is set towards the front and upward to guide the mixed cooling airflow and ambient airflow to flow forward and upward.

[0098] Understandably, when the air guide plate 600 is arranged in the front-to-back direction with its inner side facing upwards, a portion of the cooling airflow flowing out from above the air guide plate 600 will flow forward out of the air outlet 120. Simultaneously, when the inner side 240 of the air guide wing 200 faces the air outlet 120 and the second air-guiding end 231 faces backwards, an air-guiding gap 300 can be formed between the second wing 230 and the bottom outer wall of the housing 100. A portion of the cooling airflow flowing out from below the air guide plate 600 will create a negative pressure at a preset angle a, guiding the ambient airflow behind the second wing 230 through the air-guiding gap 300 to the preset angle a to mix with the cooling airflow there. Furthermore, at this time, the first wing 220 is tilted forward and upward, allowing the mixed airflow to flow forward and upward and mix again with the cooling airflow flowing out from above the air guide plate 600. In this way, the cooling airflow from the air outlet 120 flows forward and upward, preventing it from blowing directly onto the user. Furthermore, since the density of cooling air is greater than that of hot air, the cooling airflow flowing above the room gradually sinks, achieving a rapid cooling effect on the entire room. It's also important to understand that the cooling airflow from the air outlet 120 is a mixed airflow resulting from multiple mixing of ambient airflow with the cooling airflow via the air guide 200. This air guide 200 effectively evens out the airflow, ensuring a comfortable cooling experience for the user.

[0099] In some usage scenarios, the wall-mounted air conditioner indoor unit of this embodiment can be installed on the wall corresponding to the head of the bed. Therefore, when operating the cooling upward blowing mode, the cooling airflow can directly reach the head of the bed, preventing it from blowing directly onto the user lying in bed, thus achieving anti-direct blowing and ensuring a better user experience. In other usage scenarios, the wall-mounted air conditioner indoor unit of this embodiment can be installed on the wall behind the head of the bed. Similarly, when operating the cooling upward blowing mode, the cooling airflow will not blow directly onto the user lying in bed, thus achieving anti-direct blowing and ensuring a better user experience.

[0100] Reference Figure 9 In this embodiment, the indoor unit of the wall-mounted air conditioner operates in a front-blowing cooling mode. In the front-blowing cooling mode, the air guide plate 600 is arranged in the front-back direction, and the inner side of the air guide plate 600 is set upward.

[0101] In the forward-blowing cooling mode, the outer side 250 of the air guide 200 faces the air outlet 120, and the first air-guiding end 221 faces the rear. An air-guiding gap 300 is provided between the first wing plate 220 and the bottom outer wall of the housing 100. The air-guiding gap 300 is used to guide the ambient airflow at the bottom of the housing 100 to a preset angle a and mix it with the cooling airflow when the cooling airflow flows out of the air outlet 120. The second air-guiding end 231 is positioned forward and downward so that the mixed cooling airflow and ambient airflow can be made to flow forward through the first wing plate 220.

[0102] Understandably, when the air guide plate 600 is arranged in the front-to-back direction and its inner side faces upward, a portion of the cooling airflow flowing out from above the air guide plate 600 will flow forward out of the air outlet 120. Furthermore, when the outer side 250 of the air guide wing 200 faces the air outlet 120 and the first air-guiding end 221 faces backward, an air-guiding gap 300 can be formed between the first wing plate 220 and the bottom outer wall of the housing 100. A portion of the cooling airflow flowing out from below the air guide plate 600 will create a negative pressure in the space above the first wing plate 220 in front of the bottom of the air outlet 120, guiding the ambient airflow behind the first wing plate 220 through the air-guiding gap 300 to the space where the negative pressure is formed, mixing with the cooling airflow there. At this time, the second wing plate 230 is tilted forward and downward, and the first wing plate 220 can promote the mixed airflow to flow forward and mix again with the cooling airflow flowing out from above the air guide plate 600. Therefore, the cooling airflow exiting the air outlet 120 will flow forward, preventing it from blowing directly onto the user. Furthermore, because the density of cooling airflow is greater than that of hot airflow, the cooling airflow flowing above the indoor space will gradually sink, achieving a rapid cooling effect on the entire indoor space. It is also important to understand that the cooling airflow exiting the air outlet 120 is a mixed airflow resulting from multiple mixing of the ambient airflow with the cooling airflow through the air guide 200. Thus, the air guide 200 can evenly distribute the airflow, ensuring a comfortable cooling experience for the user.

[0103] In some usage scenarios, the wall-mounted air conditioner indoor unit of this embodiment can be installed on the wall corresponding to the head of the bed. Therefore, when operating the front-blowing cooling mode, the cooling airflow can directly reach the head of the bed, preventing it from blowing directly onto the user lying in bed, thus achieving anti-direct-blowing and ensuring a better user experience. In other usage scenarios, the wall-mounted air conditioner indoor unit of this embodiment can be installed on the wall behind the head of the bed. Similarly, when operating the front-blowing cooling mode, the cooling airflow will not blow directly onto the user lying in bed, thus achieving anti-direct-blowing and ensuring a better user experience.

[0104] Reference Figure 10 In this embodiment, the indoor unit of the wall-mounted air conditioner operates in a cooling down-blowing mode. In the cooling down-blowing mode, the air guide plate 600 is arranged at an angle downwards and forwards, and the inner side of the air guide plate 600 is set downwards and backwards.

[0105] In the cooling down-blowing mode, the outer side 250 of the air guide vane 200 is set towards the air outlet 120, the second air guide end 231 is set towards the inner side of the air guide plate 600, and the first air guide end 221 is set towards the bottom to guide the cooling airflow downward.

[0106] Understandably, in the cooling down-blowing mode, the air guide plate 600 is arranged at an angle downwards and forwards, with its inner side facing downwards and backwards. In this mode, the air guide plate directs most of the airflow within the air outlet duct 110 to the air guide vane 200. Simultaneously, the outer side 250 of the air guide vane 200 faces the air outlet 120, and the second air-guiding end 231 faces upwards and forwards towards the inner side of the air guide plate 600, meaning the air guide vane 200 is in a vertical position. The cooling airflow flowing from the air guide plate 600 to the air guide vane 200 can be guided downwards by the vertically positioned air guide vane 200 through the space between the air guide vane 200 and the air guide plate 600, and between the air guide vane 200 and the bottom of the air outlet 120, causing the cooling airflow to blow downwards. At this time, the overall cooling airflow from the air outlet 120 will flow downwards, preventing direct airflow to the user and ensuring a better user experience.

[0107] In addition, in some usage scenarios, the wall-mounted air conditioner indoor unit of this embodiment can be installed on the wall corresponding to the head of the bed. Thus, when the cooling down-blowing mode is running, the cooling airflow can blow directly to the foot of the bed, or even not blow on the bed at all, so as not to blow on the user lying in bed, thereby achieving anti-direct blowing and ensuring the user's experience.

[0108] Reference Figure 11 In this embodiment, the indoor unit of the wall-mounted air conditioner operates in a heating down-to-front blowing mode. In the heating down-to-front blowing mode, the air guide plate 600 is arranged at an angle to the front and downward, and the inner side of the air guide plate 600 is set to the rear and downward.

[0109] In the front-blowing mode under heating, the inner side 240 of the air guide wing 200 faces the air outlet 120, the first air intake end 221 faces the rear and upward, the first wing plate 220 is located between the bottom of the air outlet 120 and the air guide plate 600, and the second air intake end 231 faces the rear and downward.

[0110] Understandably, in the forward-blowing heating mode, the air guide plate 600 is arranged at an angle downwards and forwards, with its inner side facing downwards and backwards. In this mode, the air guide plate 600 can guide most of the airflow within the air outlet duct 110 to the air guide vane 200 via its inner side. Simultaneously, the inner side 240 of the air guide vane 200 faces the air outlet 120, the first air intake end 221 faces upwards and backwards, the first wing plate 220 is located between the bottom of the air outlet 120 and the air guide plate 600, and the second air intake end 231 faces downwards and backwards, meaning the air guide vane 200 is in a vertical position. Therefore, the heating airflow flowing from the air guide plate 600 to the air guide vane 200 can flow downwards and forwards along the inner and outer sides 250 of the air guide vane 200 from the space between the air guide vane 200 and the air guide plate 600, and from the space between the air guide vane 200 and the bottom of the air outlet 120, respectively, resulting in a forward-blowing heating airflow. Furthermore, because the density of the heating airflow is lower than that of the cooling airflow, the heating airflow flowing from the bottom of the indoor space will gradually rise, thus achieving a rapid heating effect on the entire indoor space. At the same time, the downward-facing heating mode prevents the hot airflow from blowing directly onto the room.

[0111] Reference Figure 12 In this embodiment, the indoor unit of the wall-mounted air conditioner also operates in a heating down-and-back blowing mode. In the heating down-and-back blowing mode, the air guide plate 600 is arranged along the top and bottom, and the inner side of the air guide plate 600 is set facing the rear and downward.

[0112] In the rear-blowing heating mode, the inner side 240 of the air guide 200 faces the air outlet 120, the first air intake end 221 is close to or faces the inner side of the air guide plate 600, the first wing plate 220 is located between the bottom end of the air outlet 120 and the air guide plate 600, and the second air intake end 231 is arranged to the rear and downward, so as to promote the heating airflow from the air outlet 120 to the wall where the wall-mounted air conditioner indoor unit is installed to flow backward, or to promote the heating airflow to flow downward.

[0113] Understandably, in the rear-blowing heating mode, the air guide plate 600 is arranged at an angle downwards and forwards, with its inner side facing downwards and backwards. In this mode, the air guide plate 600 directs most of the airflow within the outlet duct 110 to the air guide vane 200 via its inner side. Simultaneously, the inner side 240 of the air guide vane 200 faces the air outlet 120, and the first air intake end 221 is positioned close to or towards the inner side of the air guide plate 600. Consequently, a smaller amount of heating airflow flows through the space between the air guide vane 200 and the air guide plate 600, while most of the heating airflow flows through the space between the bottom of the air guide vane 200 and the air outlet 120. However, all heating airflow flows along the inner and outer sides 250 of the air guide vane 200. Furthermore, because the second air intake end 231 of the air guide vane 200 is angled backwards, the overall heating airflow flows downwards and backwards towards the wall where the indoor unit of the wall-mounted air conditioner is installed. The heating airflow, which flows to the bottom of the indoor space, gradually rises to quickly heat the entire space. Furthermore, as the heating airflow moves towards the wall where the wall-mounted air conditioner unit is installed, it flows downwards close to the wall to minimize the risk of the airflow blowing directly onto the user. Simultaneously, due to the adhesion of the airflow, its downward speed decreases, ensuring continuous heating of the indoor space at different heights, thus guaranteeing the heating effect of the wall-mounted air conditioner unit and ensuring a superior user experience.

[0114] Reference Figure 12 In this embodiment, in the heating down-blowing mode, the air guide vane 200 is configured to rotatably adjust the distance between the first air intake end 221 and the air guide plate 600, so as to adjust the flow angle of the heating airflow between downward and backward, so that the flow angle of the heating airflow can meet the user's needs and ensure the user experience.

[0115] Furthermore, by rotating the air guide vane 200 in the rear-blowing mode under heating, the heating airflow can flow within a flow angle range of 70° to 90°. This flow angle is the angle between the heating airflow and the bottom outer wall of the housing 100. In the rear-blowing mode under heating, as the distance between the first air intake end 221 and the air guide plate 600 is adjusted, the first air intake end 221 can be positioned facing forward and upward, directly upward, or backward and upward.
