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 an arc-shaped air guide vane. 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 airflow effect of the indoor unit are crucial to the user experience. To adjust the airflow direction, a rotatable air guide vane structure is usually installed. Traditional horizontal air guide vanes mostly adopt a single flat plate structure. While this structure can change the direction of airflow to some extent when adjusting the airflow direction, it suffers from problems such as a single airflow mode and a limited airflow range.

[0003] Currently, in existing technologies, fixed irregularly shaped air guide structures or deflectors are typically added to the air outlet to diversify the air supply modes of the air conditioner. However, such air guide structures reduce airflow fluidity when guiding airflow, leading to increased airflow loss, which in turn results in poor air supply performance for each air outlet mode of the indoor unit. Utility Model Content

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

[0021] 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; and...

[0022] 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.

Because at least a portion of the inner surface of the air guide vane is curved, the airflow exhibits excellent fluidity and low wind loss when the inner surface of the air guide vane guides the airflow exiting the air outlet.

[0053] The following is combined 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.

[0054] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the wall-mounted air conditioner indoor unit may include a housing 100 and an air guide vane 200.

[0055] The lower front part of the housing 100 has a horizontally extending air outlet 120.

[0056] 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, so that the air guide 200 is constructed to have an inner surface 240 forming the preset included angle α. The inner surface 240 of the air guide 200 includes a wind-guiding arc surface 241, which is disposed adjacent to the rotation axis 210 of the air guide 200.

[0057] Because the wall-mounted air conditioner indoor unit of this embodiment has at least a portion of the inner surface 240 of the air guide 200 as an arc surface, when the inner surface 240 of the air guide 200 guides the airflow flowing out of the air outlet 120, the airflow can have good fluidity and low wind loss. Therefore, this embodiment can ensure the fluidity of the airflow when it flows through the air guide 200, so that the airflow has less wind loss and improves the air outlet effect of the air conditioner indoor unit.

[0058] 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 are 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. Therefore, the air guide wing 200 can be rotatably disposed on the outside of the air outlet 120. Furthermore, the driving device can be disposed on the left mounting bracket 510 and / or the right mounting bracket 520.

[0059] Reference Figure 1 and Figure 2 In 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.

[0060] Reference Figure 4 In this embodiment, the inner surface 240 of the wind vane 200 may further include a first wind-guiding plane 242 and a second wind-guiding plane 243.

[0061] The first air guide plane 242 is located on the first wing plate 220, and the first air guide plane 242 is connected to one side of the air guide arc surface 241. The tangent M at the intersection of the air guide arc surface 241 and the first air guide plane 242 is parallel to the first air guide plane 242.

[0062] The second air guide plane 243 is located on the second wing plate 230, and the second air guide plane 243 is connected to the other side of the air guide arc surface 241. The tangent at the intersection of the air guide arc surface 241 and the second air guide plane 243 is parallel to the second air guide plane 243.

[0063] It is understandable that the portions or ends of the first wing plate 220 and the second wing plate 230 that are away from the rotation axis 210 serve to guide the airflow in the air outlet duct 110 to the inner surface 240 or outer surface 250 of the guide vane 200. Therefore, setting both sides of the guide arc surface 241 as flat can further enhance the air guiding effect of the guide vane 200.

[0064] The tangent M at the intersection of the air guide arc surface 241 and the first air guide plane 242 is parallel to the first air guide plane 242, and the tangent at the intersection of the air guide arc surface 241 and the second air guide plane 243 is parallel to the second air guide plane 243. This ensures the smooth flow of air in the air outlet duct 110 between the first air guide plane 242 (or the second air guide plane 243) and the air guide arc surface 241, thereby further reducing the air loss of air flowing on the inner side 240 of the air guide wing 200 and further improving the air outlet effect of the wall-mounted air conditioner indoor unit.

[0065] Reference Figure 3 and Figure 4 In this embodiment, the distance N from the intersection of the wind-guiding arc surface 241 and the first wind-guiding plane 242 to the rotation axis 210 is greater than or equal to one-third of the wing width K of the first wing plate 220, where the wing width K is the width of the first wing plate 220 in the direction away from the rotation axis 210. Furthermore, the distance N from the intersection of the wind-guiding arc surface 241 and the second wind-guiding plane 243 to the rotation axis 210 is greater than or equal to one-third of the wing width K of the second wing plate 230, where the wing width K is the width of the second wing plate 230 in the direction away from the axis of rotation center 610.

[0066] Understandably, setting the distance N from the intersection of the air guide arc surface 241 and the first air guide plane 242 to the rotation axis 210 is greater than or equal to one-third of the wing width K of the first wing plate 220. Furthermore, setting the distance from the intersection of the air guide arc surface 241 and the second air guide plane 243 to the rotation axis 210 is greater than or equal to one-third of the wing width K of the second wing plate 230 ensures the width of the air guide arc surface 241, further guaranteeing the flow of air through the inner surface of the air guide wing 200, thereby further improving the air outlet performance of the wall-mounted air conditioner indoor unit.

[0067] Reference Figure 4 and Figure 5 In this embodiment, the thickness Q at the connection between the first wing plate 220 and the second wing plate 230 is less than or equal to one-fifth of the width T of the air outlet 120 in the front-rear direction.

[0068] It is understandable that the curvature b of the air guide surface 241 can be determined by the preset included angle a and the thickness Q of the air guide wing 200. Furthermore, by setting the thickness Q at the connection between the first wing plate 220 and the second wing plate 230 to be less than or equal to one-fifth of the width T of the air outlet 120 in the front-to-back direction, that is, setting the thickness of the thickest part of the air guide wing 200 to be less than or equal to one-fifth of the width T of the air outlet 120 in the vertical direction, the curvature of the air guide surface 241 is ensured, further ensuring the flow of air through the air guide surface 241 and further ensuring that the airflow has low wind loss. Especially when the indoor unit of the wall-mounted air conditioner is operating in the heating down front-blowing mode and the heating down rear-blowing mode, the flow rate of the heating airflow on the inner surface 240 of the air guide wing 200 is relatively large. Setting the thickness of the thickest part of the air guide wing 200 to be less than or equal to one-fifth of the width T of the air outlet 120 in the vertical direction can effectively ensure the flow of the heating airflow on the inner surface 240 of the air guide wing 200.

[0069] In this embodiment, the preset included angle α can be greater than or equal to 90° and less than 180°, allowing the guide vane 200 to be V-shaped to change the airflow direction and ensure the diversity of airflow direction guidance provided by the guide vane 200, while avoiding excessive airflow obstruction due to an excessively large preset included angle α. Furthermore, within the range specified in this embodiment, the preset included angle α allows the guide vane 200 plate to simultaneously accommodate both upward blowing of cooling airflow and downward blowing of heating airflow.

[0070] In this embodiment, the preset included angle α can be greater than or equal to 130° and less than or equal to 160°, in order to further ensure the diversity of airflow direction guidance by the guide vane 200 and further avoid the situation where the preset included angle α is too large and obstructs the airflow too much. Moreover, within the range specified in this embodiment, the preset included angle α can enable the guide vane 200 plate to simultaneously accommodate the operation of cooling airflow upward blowing and heating airflow downward blowing modes.

[0071] In this embodiment, the preset included angle α can be greater than or equal to 140° and less than or equal to 150°, so as to ensure the diversity of air outlets while also optimizing the guiding effect of the airflow by the guide vane 200. Furthermore, within the range specified in this embodiment, the preset included angle α allows the airflow guide vane 200 plate to simultaneously accommodate both upward blowing of cooling airflow and downward blowing of heating airflow.

[0072] 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.

[0073] 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.

[0074] Reference Figure 3 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.

[0075] Reference Figure 3 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.

[0076] Reference Figure 3 In this embodiment, the wall-mounted air conditioner indoor unit also includes an air guide plate 600.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] Understandably, the clearance groove 112 ensures the rotatability of the air guide plate 600. Furthermore, in certain 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 within the air outlet duct 110 can flow out of the air outlet 120 through the clearance groove 112, thus ensuring the air supply range of the wall-mounted air conditioner indoor unit.

[0081] Reference Figure 3 In 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 6 and Figure 7 In this embodiment, the indoor unit of the wall-mounted air conditioner 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 240 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, wherein the outer side 250 of the air guide 200 and the inner side 240 of the air guide 200 are set opposite to each other.

[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] Reference Figure 7 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.

[0086] Reference Figure 6 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 extension line 111 of the duct.

[0087] 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 to ensure the fluidity of the outlet airflow as it flows from the bottom of the outlet duct 110 towards the first wing plate 220, thus ensuring the flow rate of the outlet airflow.

[0088] Reference Figure 7 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.

[0089] 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.

[0090] Reference Figure 7 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.

[0091] Reference Figure 7In this embodiment, the axial distance H between the rotation axis 210 of the wind vane 200 and the bottom outer wall of the housing 100 is greater than or equal to 10 mm and less than or equal to 60 mm.

[0092] 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.

[0093] Reference Figure 3 In this embodiment, 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.

[0094] It is understandable that the width K of the first wing plate 220 and the second wing plate 230 of the air guide 200 is set to be the same. Therefore, with sufficient space for either the first wing plate 220 or the second wing plate 230 to pass through between the air guide 200 and the bottom of the air outlet 120, the air guide 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, the wall-mounted air conditioner indoor unit of this invention improves the rotational flexibility of the air guide 200 and further enhances the versatility of the airflow from the wall-mounted air conditioner indoor unit.

[0095] Reference Figure 3 and Figure 7 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.

[0096] 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 10 and Figure 11The 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.

[0097] Reference Figure 3 and Figure 7 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.

[0098] It is understandable that the wing width K of the first wing plate 220 is set to be greater than 20mm and less than the length L of the air duct extension line 111, so as to ensure the guiding effect of the air guide wing 200 on the airflow flowing out of the air outlet 120, and at the same time avoid the situation where the rotation of the air guide wing 200 is interfered with by other components of the wall-mounted air conditioner indoor unit.

[0099] Reference Figure 3 and Figure 7 In this embodiment, the wing width K of the first wing 220 is greater than 20 mm and less than two-thirds of the length L of the duct extension line 111.

[0100] 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.

[0101] 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 240 of the air guide plate 600 is set upward.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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 240 of the air guide plate 600 is set upward.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] Reference Figure 10In 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 to the front and downward, and the inner side 240 of the air guide plate 600 is arranged to the rear and downward.

[0110] 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 240 of the air guide plate 600, and the first air guide end 221 is set towards the bottom to guide the cooling airflow downward.

[0111] 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 exiting the air outlet 120 will flow downwards, preventing direct airflow to the user and ensuring a better user experience.

[0112] 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.

[0113] 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 240 of the air guide plate 600 is set to the rear and downward.

[0114] 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.

[0115] 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 240 of the air guide plate 600 is set facing the rear and downward.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] Furthermore, by rotating the air guide vane 200 in the heating down-and-back blowing mode, 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 heating down-and-back blowing mode, 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.

[0120] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
