Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to a wall-mounted air conditioning indoor unit. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] Currently, more and more people are choosing to install air conditioners indoors to regulate the temperature of the indoor air. Wall-mounted air conditioners are one type of air conditioner, and their flexible installation location, high cost-effectiveness, and wide applicability make them the first choice for most families when selecting an air conditioner.

[0004] Traditional bedroom air conditioners have a small air delivery range, and the cold air is easily blown on people, causing discomfort and potentially leading to "air conditioning sickness." Current air conditioning technologies generally control the direction and speed of the airflow, but directional airflow, due to reflections from walls, can still create a large temperature difference and a feeling of being blown around, affecting comfort. Utility Model Content

[0005] This application discloses a wall-mounted air conditioner indoor unit that can deliver air to the ceiling, the floor, or both directions simultaneously. The air guide is used to assist in air guidance, resulting in better air guidance and enhanced user experience and comfort.

[0006] To achieve the above objectives, some embodiments of this application provide a wall-mounted air conditioner indoor unit, comprising: a casing, the casing having a casing air inlet and a casing air outlet, the casing air outlet including: an upper air outlet disposed at the top front side of the casing; and a lower air outlet, at least a portion of which is disposed at the bottom of the casing; the casing containing: a heat exchanger for exchanging heat with airflow flowing into the casing; and a fan for introducing airflow from the casing air inlet into the casing and exchanging heat with the heat exchanger. The air is then delivered into the room through the air outlet of the casing; a flow divider, located on the front side of the fan, allows the airflow blowing onto the flow divider to flow upward and downward; a volute, disposed inside the casing, forming a heat exchange air duct, the air inlet of the heat exchange air duct communicating with the air inlet of the casing, the air outlet of the heat exchange air duct facing the flow divider, the volute including: a front volute tongue, the front volute tongue including: a first surface, the first surface gradually sloping upward in the direction from the rear side to the front side of the casing; a second surface The second surface gradually slopes downwards in the direction from the rear to the front of the housing, and the first and second surfaces form an air outlet; an upper air duct is located above the front volute and extends towards the upper air outlet, forming an upper air duct communicating with the upper air outlet between the upper air duct and the diverter along the thickness direction of the housing, and the upper air duct is configured to guide the airflow entering the upper air duct to be delivered outwards through the upper air outlet; a lower air duct is located below the front volute and extends towards... The lower air outlet extends along the thickness direction of the housing, and a lower air duct is formed between the lower air duct component and the diverter component, communicating with the lower air outlet. The lower air duct component is configured to guide airflow vertically downward through the lower air outlet. A turbulence-disrupting component is movably disposed between the upper air duct and the lower air duct. The turbulence-disrupting component is movable between a first position, a second position, and a third position. The turbulence-disrupting component includes: a wind deflector; and a wind guide component, fixed relative to the wind deflector. A ventilation gap is formed between the wind deflector and the wind guide component.

[0007] Thus, the first surface of the front volute tongue is tilted upwards, naturally connecting with the direction of the upper airflow channel. This guides the airflow flowing towards the front volute tongue side to smoothly deflect upwards along the tilted surface, reducing turbulence and resistance caused by sudden changes in direction. The second surface is tilted downwards, precisely matching the path of the lower airflow channel. This guides the airflow flowing towards the volute side to flow smoothly downwards along the tilted surface, avoiding energy loss caused by airflow impacting the airflow channel wall.

[0008] This embodiment achieves simultaneous airflow from both the top and bottom by setting up upper and lower air outlets. During cooling, the cold air from the upper outlet diffuses upwards, utilizing the sinking property of cold air to ensure even and natural settling, avoiding direct airflow onto the body. During heating, the hot air from the lower outlet is directed directly to the ground, conforming to the principle of hot air rising, allowing warmth to spread from the feet to the whole body. This top-and-bottom airflow method enhances user comfort. Furthermore, with a fixed airflow volume, according to the wind speed calculation formula (wind speed = airflow ÷ outlet cross-sectional area), increasing the cross-sectional area of ​​the outlet by adding an upper air outlet reduces the airflow speed. Lower wind speed avoids the discomfort of strong winds, making the airflow gentler and less impactful, further enhancing the user experience.

[0009] By connecting the upper air duct to the upper air outlet and the lower air duct to the lower air outlet, and in conjunction with a baffle component that can move between these three positions, the wall-mounted air conditioner indoor unit can mechanically switch between three modes: simultaneous upper and lower air supply, lower air supply, and upper air supply. Users do not need to purchase two separate air conditioners or repeatedly adjust the louvers. They can choose from three scenarios with a single button: cool air directed towards the ceiling (upper air supply mode), warm air directed towards the floor (lower air supply mode), or balanced air supply throughout the room (simultaneous upper and lower air supply mode), achieving "one unit, three uses," based on the season, population distribution, or personal comfort needs. Furthermore, in this embodiment, the wind deflector blocks unnecessary air ducts, and the air guide works in conjunction with the airflow to guide it to the ducts where air needs to be supplied. The addition of the air guide further assists in airflow guidance under the blocking effect of the wind deflector. The ventilation gap creates a directional guiding channel for airflow as it passes through the baffle component (between the air guide plate and the wind deflector), preventing disorderly airflow diffusion and enhancing the air supply effect of each mode, thus improving user experience and comfort.

[0010] As an optional implementation, when the turbulence-disrupting component is in the first position, the wind deflector avoids the upper and lower air ducts, and the air guide is used to divert the airflow from the outlet side of the fan to the upper and lower air ducts. When the turbulence-disrupting component is in the second position, the wind deflector can block at least part of the upper air duct, and the air guide is used to guide the airflow from the outlet side of the fan to the lower air duct. When the turbulence-disrupting component is in the third position, the wind deflector can block at least part of the lower air duct.

[0011] Thus, when the turbulence component 5 is in the first position, the air guide 52 guides part of the airflow from the outlet side of the fan 2 to the upper air duct 3a, which is less prone to airflow, thereby increasing the airflow volume of the upper air duct 3a. When the turbulence component 5 is in the second position, the wind deflector 51 can block at least part of the upper air duct 3a, and the air guide 52 guides the airflow to the lower air duct 3b, which remains unobstructed, reducing the possibility of airflow entering the upper air duct 3a and ensuring the airflow volume of the lower air duct 3b. When the turbulence component 5 is in the third position, the wind deflector 51 blocks at least part of the lower air duct 3b, thereby allowing most of the airflow to enter the upper air duct 3a. Therefore, the addition of the air guide 52 can further assist in airflow guidance under the blocking effect of the wind deflector 51, enhance the air supply effect of each mode, and enhance the user experience and comfort.

[0012] As an optional implementation, when the turbulence-disrupting component is in the first position, the ventilation gap can guide the airflow on the outlet side of the fan to the upper air duct, and when the turbulence-disrupting component is in the second position, the ventilation gap can guide the airflow on the outlet side of the fan to the lower air duct.

[0013] Thus, when the turbulence-disrupting component is in the first position, the gap can also guide some airflow to the upper air duct; when the turbulence-disrupting component is in the second position, the gap can also directionally guide the airflow to the lower air duct. While achieving air diversion by blocking the wind deflector and guiding the airflow towards the side of the fan, the ventilation gap between the air guide and the wind deflector can further guide the airflow distribution, reducing the possible interference to the airflow caused by the addition of the air guide, avoiding turbulence and resistance caused by airflow impact, and allowing more wind energy to be effectively delivered to the target air outlet (upper air outlet or lower air outlet), thus improving the utilization rate of the fan's air output.

[0014] As an optional implementation, the ventilation gap includes a first end and a second end disposed opposite to each other, and the ventilation gap gradually decreases along the direction from the first end to the second end.

[0015] Thus, as airflow passes through the gap from the first end to the second end, the velocity gradually increases as the cross-sectional area decreases, thereby enhancing the kinetic energy of the airflow. This allows the airflow to flow more powerfully towards the target duct after passing through the gap, reducing diffusion losses and increasing the air delivery distance and coverage. Conversely, as airflow passes through the gap from the first end to the second end, the velocity gradually decreases as the cross-sectional area increases, resulting in a smoother flow. By rotating the baffle component to different modes, the flow direction of the airflow within the gap changes, achieving different effects. Simultaneously, the gradually changing gap size guides the airflow along a smooth path, avoiding turbulence caused by abrupt changes in cross-section, and reducing wind resistance and noise.

[0016] In one optional implementation, when the turbulence component is in the first position, the first end is the air inlet and the second end is the air outlet; when the turbulence component is in the second position, the second end is the air inlet and the first end is the air outlet.

[0017] Thus, when the deflector is in the first position, the airflow flows from the first end to the second end and then into the upper duct. Due to gravity, the airflow is less likely to flow into the upper duct. As the airflow passes through the ventilation gap, the velocity gradually increases, thereby enhancing the kinetic energy of the airflow. This allows the airflow to flow more forcefully into the upper duct after passing through the gap, reducing diffusion loss and increasing the air delivery distance and coverage area in the upper duct, ensuring the airflow volume in the upper duct. When the deflector is in the second position, the airflow flows from the second end to the first end and then into the lower duct. Due to gravity, the airflow is more likely to flow into the lower duct. As the airflow passes through the ventilation gap, the velocity gradually decreases, thus preventing the airflow from becoming too fast under the combined effects of gravity and the guidance of the ventilation gap, which would affect the user experience.

[0018] As an optional implementation, the turbulence component is rotatable between a first position, a second position, and a third position, with the rotation axes of the wind deflector and the air guide disposed close to the first end.

[0019] Thus, by rotating around a fixed axis, the airflow deflector can quickly switch between the first, second, and third positions, thereby achieving various modes such as single upward airflow, single downward airflow, and simultaneous bidirectional airflow. Without the need for complex multi-component linkages, only a single drive mechanism (such as a small motor) is required to complete the attitude adjustment, resulting in faster response and simpler operation logic. This allows users to quickly switch to the optimal airflow state according to their usage scenario (such as upward airflow during cooling and downward airflow during heating). Furthermore, the rotating connection ensures continuous attitude adjustment of the airflow deflector, allowing for precise control of the baffle area and guide angle of the air guide by fine-tuning the angle, thereby distributing the airflow direction. Additionally, the rotation of the airflow deflector occupies less space than linear movement, saving internal space in the indoor unit.

[0020] Furthermore, because the rotation axis is close to the first end of the ventilation gap, the turbulence component can achieve attitude adjustment with a shorter lever arm when switching positions. This not only reduces the load on the drive mechanism but also allows the turbulence component to switch quickly between the first, second, and third positions, reducing the response time for mode switching. When switching from bidirectional air supply (first position) to single downward air supply (second position), only a small rotation is needed to complete the obstruction of the upper air duct by the baffle and the guidance adjustment of the air guide, improving the convenience of operation and the energy efficiency of the entire unit.

[0021] As an optional implementation, the windbreak is a straight plate and the air guide is an arc-shaped plate.

[0022] Thus, the straight plate has a flat shielding surface. When the airflow deflector is in the second position (shielding the upper airflow duct) or the third position (shielding the lower airflow duct), it can form a closer planar contact or a small gap fit with the inner wall of the airflow duct (such as the front volute), which can more effectively block airflow compared to the curved structure. At the same time, the straight structure is more rigid and is not easily deformed by airflow impact during long-term use, which can stably maintain the shielding effect and improve the reliability of the air supply mode.

[0023] Secondly, the curved plate's air guide significantly optimizes the smoothness and efficiency of airflow guidance. The curved surface design conforms to the natural flow trajectory of airflow, guiding it to smoothly change direction along the curved surface, reducing airflow separation and turbulence caused by right angles or abrupt structural changes. When the turbulence-disrupting component is in the first position (bidirectional airflow), the curved air guide gently diverts the airflow from the fan to the upper and lower ducts, reducing wind resistance loss. In the second position (downward airflow), the curved surface guides the airflow downwards, creating a more concentrated airflow direction. Simultaneously, the curved structure allows the airflow to form a more stable wall-attached flow when passing through ventilation gaps. Combined with the acceleration effect of the gradually changing gaps, this further increases the airflow distance and coverage, reducing energy loss caused by airflow diffusion.

[0024] As an optional implementation, the wall-mounted air conditioner indoor unit further includes: a rotating shaft disposed within the air duct; a rotating base rotatably connected to the housing via the rotating shaft, wherein the wind deflector and the air guide are both connected to the rotating base.

[0025] In this way, the wind deflector and air guide are integrated into a single unit via the rotating base, rotating synchronously around the same axis. This avoids positional deviations or action delays that might occur due to their independent movement. During mode switching, the wind deflector's obstruction of the air duct and the air guide's airflow guidance work precisely together. This ensures that in the second position, the wind deflector reliably blocks the upper air duct while the air guide simultaneously directs the airflow to the lower air duct, reducing airflow leakage and improving the reliability of the air supply mode. Simultaneously, the structural strength of the rotating base disperses the stress generated by airflow impact, reducing the risk of deformation of the wind deflector or air guide due to long-term stress and extending the component's lifespan.

[0026] Secondly, it simplifies the assembly process and reduces maintenance costs. The wind deflectors and air guides can be pre-assembled on the rotating base before being installed as a whole into the casing, reducing assembly steps and precision requirements within the air duct and improving production efficiency. During later maintenance, the entire airflow turbulence assembly can be replaced by disassembling the rotating base, eliminating the need to individually adjust the position of the wind deflectors or air guides, thus reducing maintenance difficulty and time costs. Furthermore, this integrated design reduces the number of parts, helping to control the overall weight and manufacturing costs.

[0027] As an optional implementation, when the airflow turbulence component is in the first position, the air guide includes a third end and a fourth end opposite to each other, the fourth end being closer to the upper air outlet relative to the third end, the first surface includes a fifth end and a sixth end opposite to each other, the sixth end being closer to the upper air outlet relative to the fifth end, and the distance between the third end and the fifth end is greater than the distance between the fourth end and the sixth end.

[0028] Thus, when the turbulence component is in the first position, when the airflow flows from the fan outlet side to the upper air duct, it must first pass through the fifth end of the front volute and the third end of the air guide, then through the sixth end of the front volute and the fourth end of the air guide, before entering the upper air duct. Due to gravity, the airflow is less likely to flow to the upper air duct. When the airflow passes between the first air guide surface and the air guide, the flow velocity increases due to the reduced distance (i.e., the cross-sectional area of ​​the airflow channel is reduced), thereby enhancing the kinetic energy of the airflow. This allows the airflow to flow more forcefully to the upper air duct after passing through the gap, reducing diffusion loss and increasing the air delivery distance and coverage of the airflow in the upper air duct, thus ensuring the air volume in the upper air duct.

[0029] As an optional implementation, when the spoiler component is in the second position, the minimum distance between the end of the wind deflector near the front volute and the front volute is 5mm to 8mm;

[0030] When the turbulence component is in the third position, the wind deflector abuts against the volute.

[0031] Thus, when the spoiler component is in the second position, if the gap is too small (less than 5mm), friction between the two components may occur due to manufacturing errors or vibration, generating noise. Furthermore, when the spoiler component rotates from the second position to the third position, it may be unable to continue rotating due to the small gap. If the gap is too large (greater than 8mm), excessive airflow will leak into the upper air duct, weakening the airflow in the downward airflow mode. The minimum gap design of 5mm to 8mm between the wind deflector and the front volute balances the shielding effect and airflow stability. This gap effectively blocks most of the airflow from entering the upper air duct (ensuring that the airflow mode is primarily downward airflow) while avoiding direct contact between the wind deflector and the front volute.

[0032] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0033] By incorporating upper and lower air ducts, upper and lower air outlets, and aerodynamic components that can move in different positions, the indoor air conditioning unit can achieve multiple air delivery modes. When the aerodynamic component is in its first position, the deflector avoids the upper and lower air ducts, and the air guide diverts the airflow from the fan outlet side to the upper and lower air ducts. This allows for simultaneous upward and downward bidirectional air delivery, meeting the temperature requirements of different areas indoors and improving overall comfort. The air guide within the aerodynamic component is fixed relative to the deflector. While the deflector blocks the air duct, the air guide assists in guiding the airflow. The ventilation gap creates a directional guiding channel for the airflow as it passes through the aerodynamic component (between the air guide plate and the deflector plate), resulting in better airflow and enhanced user experience and comfort.

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] Currently, more and more people are choosing to install air conditioners indoors to regulate the temperature of the indoor air. Wall-mounted air conditioners are one type of air conditioner, and their flexible installation location, high cost-effectiveness, and wide applicability make them the first choice for most families when selecting an air conditioner.

[0055] Traditional bedroom air conditioners have a small air delivery range, and the cold air is easily blown on people, causing discomfort and potentially leading to "air conditioning sickness." Current air conditioning technologies generally control the direction and speed of the airflow, but directional airflow, due to reflections from walls, can still create a large temperature difference and a feeling of being blown around, affecting comfort.

[0056] Based on this, this application provides a wall-mounted air conditioner indoor unit that supplies air from both the top and bottom simultaneously. This not only avoids direct airflow onto the human body, ensuring comfort, but also reduces the wind speed by increasing the cross-sectional area of ​​the air outlet, thus improving the uncomfortable feeling of blowing air, while maintaining a certain air volume. Furthermore, the air duct is equipped with wind deflectors and air guides that can move between three positions, enabling separate airflow to the ceiling, separate airflow to the floor, and simultaneous bidirectional airflow. The air guides further enhance the airflow guidance effect, improving the user experience and comfort.

[0057] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0058] Please see Figures 1 to 4 , Figure 1This is a first-view structural schematic diagram of the wall-mounted air conditioner indoor unit 100 disclosed in an embodiment of this application. Figure 2 This is a structural schematic diagram of the wall-mounted air conditioner indoor unit 100 disclosed in the embodiments of this application from a second-view perspective. Figure 3 This is a structural schematic diagram of the wall-mounted air conditioner indoor unit 100 disclosed in the embodiments of this application from a third-person perspective. Figure 4 The embodiments disclosed in this application Figure 1 The cross-sectional view at point AA shows that this application embodiment provides a wall-mounted air conditioner indoor unit 100. The wall-mounted air conditioner indoor unit 100 includes a casing 1, which is the basic frame of the air conditioner indoor unit and mainly consists of a top plate 13, a bottom plate, a front panel 14, and a rear panel. The top plate 13 and the bottom plate are spaced apart along the height direction of the air conditioner indoor unit, and the front panel 14 and the rear panel are spaced apart along the thickness direction of the air conditioner indoor unit. The casing 1 is provided with a casing air inlet 11 and a casing air outlet 12.

[0059] In some embodiments, the wall-mounted air conditioner indoor unit 100 includes a heat exchanger (not shown in the figure). The heat exchanger is the core component for realizing air heat exchange. The heat exchanger is used to exchange heat with the airflow flowing through the air inlet 11 of the casing. When the air conditioner is cooling, the low-temperature refrigerant flowing in the heat exchanger absorbs the heat in the airflow and cools the air. When heating, the high-temperature refrigerant releases heat to the airflow and warms the air.

[0060] In some implementations, the wall-mounted air conditioner indoor unit 100 also includes a fan 2, located inside the casing 1, which is the power source for air circulation. The fan 2 generates suction by rotating, drawing indoor air into the casing 1 through the air inlet. After heat exchange in the heat exchanger, the drawn-in air is pushed into the air duct assembly 3 by the fan 2, and finally delivered into the room through the casing air outlet 12, completing the indoor air circulation and temperature regulation process. The operation of the fan 2 is crucial for achieving airflow and heat exchange circulation; its power and operating efficiency directly affect the cooling or heating effect and air volume of the air conditioner.

[0061] In some embodiments, the wall-mounted air conditioner indoor unit 100 includes a duct assembly 3, in which a duct is formed, and the duct is connected to the air outlet side of the fan 2 and the air outlet 12 of the casing.

[0062] In some embodiments, the wall-mounted air conditioner indoor unit 100 further includes a diverter 4 located in front of the fan 2, which enables the airflow blowing to the diverter 4 to flow upward and downward.

[0063] In some embodiments, the air duct assembly 3 includes a volute 31 disposed inside the housing, and a heat exchange air duct is formed inside the volute 31. The air inlet end of the heat exchange air duct is connected to the air inlet 11 of the housing, and the air outlet end of the heat exchange air duct is directed toward the diverter 4. The volute 31 includes a front volute tongue 33, which includes a first surface 331 and a second surface 311. The first surface 331 gradually slopes upward in the direction from the rear side to the front side of the housing 1, and the second surface 311 gradually slopes downward in the direction from the rear side to the front side of the housing 1. The first surface 331 and the second surface 311 form the air outlet end.

[0064] Secondly, the first surface 331 of the front volute 33 is inclined upward, which naturally connects with the direction of the upper air duct 3a. It can guide the airflow flowing towards the front volute 33 side to smoothly deflect upward along the inclined surface, reducing turbulence and resistance caused by sudden changes in direction. The second surface 311 is inclined downward, which precisely matches the path of the lower air duct 3b. It can guide the airflow flowing towards the front volute 33 side to flow smoothly downward along the inclined surface, avoiding energy loss caused by the airflow hitting the duct wall.

[0065] In some embodiments, the wall-mounted air conditioner indoor unit 100 further includes an upper air duct 34 and a lower air duct 32. The upper air duct 34 is located above the front volute 33 and extends toward the upper air outlet 121. Along the thickness direction of the casing 1, the upper air duct 34 and the diverter 4 form an upper air duct 3a that communicates with the upper air outlet 121. The upper air duct 34 is configured to guide the airflow entering the upper air duct 3a to be delivered outward through the upper air outlet 121. The lower air duct 32 is located below the front volute 33 and extends toward the lower air outlet 122. Along the thickness direction of the casing, the lower air duct 32 and the diverter 4 form a lower air duct 3b that communicates with the lower air outlet 122. The lower air duct 32 is configured to guide the airflow to be delivered vertically downward through the lower air outlet 122.

[0066] Traditional air conditioners with single-outlet directional airflow often cause cold air to blow directly onto the body, causing discomfort and increasing the risk of air conditioning sickness. This embodiment achieves simultaneous airflow from both the upper and lower vents by setting up an upper vent 121 and a lower vent 122. During cooling, the cold air from the upper vent 121 diffuses upwards, utilizing the sinking property of cold air to ensure even and natural settling, avoiding direct airflow onto the body. During heating, the hot air from the lower vent 122 is directed directly to the ground, conforming to the principle of hot air rising, allowing warmth to spread from the feet to the whole body. This vertical airflow method enhances user comfort.

[0067] On the other hand, with a constant airflow, according to the wind speed calculation formula (wind speed = airflow ÷ outlet cross-sectional area), increasing the upper outlet 121 increases the outlet cross-sectional area, thereby reducing the outlet wind speed. A lower wind speed avoids the discomfort caused by strong winds, making the airflow gentler and less impactful, further enhancing the user experience.

[0068] In some embodiments, combined with Figure 4 , Figures 6 to 8 , Figure 6 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit 100 when the turbulence component 5 is in the first position, as disclosed in the embodiments of this application. Figure 7 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit 100 when the turbulence component 5 is in the second position, as disclosed in the embodiments of this application. Figure 8 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit 100 when the turbulence component 5 is in the third position as disclosed in the embodiments of this application. The wall-mounted air conditioner indoor unit 100 also includes the turbulence component 5, which is movably disposed in the air duct. The turbulence component 5 can move between the first position, the second position and the third position. The turbulence component 5 includes a wind deflector 51 and a wind guide 52. The wind guide 52 is fixed relative to the wind deflector 51. The wind guide 52 and the wind deflector 51 are spaced apart to form a ventilation gap 53 between the wind guide 52 and the wind deflector 51.

[0069] With the upper air duct 3a connected to the upper air outlet 121 and the lower air duct 3b connected to the lower air outlet 122, and in conjunction with the air turbulence component 5 that can move between the three positions, the wall-mounted air conditioner indoor unit 100 can mechanically switch between three modes: simultaneous upper and lower air supply mode, lower air supply mode, and upper air supply mode. Users do not need to purchase two additional air conditioners or repeatedly adjust the louvers. They can select with one click three scenarios—cool air blowing directly to the ceiling without blowing on people (upper air supply mode), warm air blowing directly to the floor to warm the feet (lower air supply mode), or balanced air supply throughout the room (simultaneous upper and lower air supply mode)—based on the season, population distribution, or physical needs, achieving "one machine for three uses."

[0070] In addition, in this embodiment, the wind deflector 51 is responsible for blocking the unnecessary air ducts, and the air guide 52 cooperates with the airflow to guide the airflow to the air duct that needs air supply.

[0071] The addition of the air guide component 52 can further assist in air guidance under the blocking effect of the wind deflector 51. The setting of the ventilation gap 53 allows the airflow to form a directional guiding channel when passing through the turbulence component 5 (between the air guide plate and the wind deflector), avoiding disorderly diffusion of airflow at this point, enhancing the air supply effect of each mode, and improving the user experience and comfort.

[0072] It should be noted that the diverter 4 can be part of the main body of the housing 1 (e.g., front panel 14), or it can be a diverter 4 added in the air duct and connected to the housing 1 to divide the air duct into an upper air duct 3a and a lower air duct 3b. This embodiment does not limit this.

[0073] It should also be noted that the air guide 52 can be a straight plate or an air guide plate with a curved cross section. This embodiment does not limit this.

[0074] Optionally, when the turbulence component 5 is in the third position, the wind deflector 51 can guide the airflow on the outlet side of the fan 2 to flow into the upper air duct 3a, that is, the wind deflector 51 tilts upward, blocking the lower air duct 3b while guiding the airflow upward into the upper air duct 3a.

[0075] In some embodiments, when the turbulence-disrupting component 5 is in the first position, the wind deflector 51 avoids the upper air duct 3a and the lower air duct 3b, and the air guide 52 is used to divert the airflow from the outlet side of the fan 2 to the upper air duct 3a and the lower air duct 3b. When the turbulence-disrupting component 5 is in the second position, the wind deflector 51 can block at least part of the upper air duct 3a, and the air guide 52 is used to guide the airflow from the outlet side of the fan 2 to the lower air duct 3b. When the turbulence-disrupting component 5 is in the third position, the wind deflector 51 can block at least part of the lower air duct 3b.

[0076] When the turbulence component 5 is in the first position, the air guide 52 guides part of the airflow from the outlet side of the fan 2 to the upper air duct 3a, which is less prone to air intake, thereby increasing the air intake volume of the upper air duct 3a. When the turbulence component 5 is in the second position, the wind deflector 51 can block at least part of the upper air duct 3a, and the air guide 52 guides the airflow to the lower air duct 3b, which remains unobstructed, reducing the possibility of airflow entering the upper air duct 3a and ensuring the airflow volume of the lower air duct 3b. When the turbulence component 5 is in the third position, the wind deflector 51 blocks at least part of the lower air duct 3b, thereby allowing most of the airflow to enter the upper air duct 3a. Therefore, the addition of the air guide 52 can further assist in air guidance under the blocking effect of the wind deflector 51, enhance the air supply effect of each mode, and enhance the user experience and comfort.

[0077] In some embodiments, the wall-mounted air conditioner indoor unit 100 further includes an upper air guide plate 71 and a lower air guide plate 72. The upper air guide plate 71 is correspondingly disposed at the upper air outlet 121 and is used to open or close the upper air outlet 121. The upper air guide plate 71 is configured to open the upper air outlet 121 when the upper air duct 3a is connected to the air outlet side of the fan 2. The lower air guide plate 72 is correspondingly disposed at the lower air outlet 122 and is used to open or close the lower air outlet 122. The lower air guide plate 72 is configured to open the lower air outlet 122 when the lower air duct 3b is connected to the air outlet side of the fan 2.

[0078] Optionally, the air guide 52 and the wind deflector 51 can be an integral structure or two separately manufactured parts. The two parts can be directly connected or connected by a connector. This embodiment does not limit this.

[0079] In some embodiments, combined with Figure 4 , Figures 5 to 7 , Figure 5 for Figure 4 An enlarged view of the airflow turbulence component 5 shows that when the airflow turbulence component 5 is in the first position, the ventilation gap 53 can guide the airflow on the outlet side of the fan 2 to flow into the upper airflow 3a. When the airflow turbulence component 5 is in the second position, the ventilation gap 53 can guide the airflow on the outlet side of the fan 2 to flow into the lower airflow 3b.

[0080] When the turbulence-disrupting component 5 is in the first position, the gap can also guide part of the airflow to the upper air duct 3a; when the turbulence-disrupting component 5 is in the second position, the gap can also guide the airflow to the lower air duct 3b. While the wind deflector 51 blocks the airflow and the air guide 52 guides the airflow to the side of the fan 2 to achieve airflow diversion, the ventilation gap 53 between the air guide 52 and the wind deflector 51 can be used to further guide the airflow distribution, reduce the possible interference to the airflow caused by the addition of the air guide 52, avoid the turbulence and resistance caused by airflow collision, and enable more wind energy to be effectively delivered to the target air outlet (upper air outlet 121 or lower air outlet 122), thereby improving the utilization rate of the air outlet of the fan 2.

[0081] In some embodiments, combined with Figure 5 The ventilation gap 53 includes a first end 531 and a second end 532 that are disposed opposite to each other, and the ventilation gap 53 gradually decreases along the direction from the first end 531 to the second end 532.

[0082] As airflow passes through the gap from the first end 531 to the second end 532, the flow velocity gradually increases as the cross-sectional area decreases, thereby enhancing the kinetic energy of the airflow. This allows the airflow to flow more powerfully towards the target duct after passing through the gap, reducing diffusion losses and increasing the air delivery distance and coverage. Conversely, as airflow passes through the gap from the first end 531 to the second end 532, the flow velocity gradually decreases as the cross-sectional area increases, resulting in a smoother flow. By rotating the flow-disrupting component 5 to different modes, the flow direction of the airflow within the gap changes, achieving different effects. Simultaneously, the gradually changing gap size guides the airflow along a smooth path, avoiding turbulence caused by abrupt changes in cross-section, and reducing wind resistance and noise.

[0083] In some embodiments, combined with Figures 5 to 7 When the turbulence component 5 is in the first position, the first end 531 is the air inlet and the second end 532 is the air outlet. When the turbulence component 5 is in the second position, the second end 532 is the air inlet and the first end 531 is the air outlet.

[0084] Thus, when the airflow deflector 5 is in the first position, the airflow flows from the first end 531 to the second end 532 and then into the upper airflow duct 3a. Due to gravity, the airflow is less likely to flow into the upper airflow duct 3a. When the airflow passes through the ventilation gap 53, the flow velocity gradually increases, thereby enhancing the kinetic energy of the airflow. This allows the airflow to flow more forcefully into the upper airflow duct 3a after passing through the gap, reducing diffusion loss and increasing the air delivery distance and coverage of the airflow in the upper airflow duct 3a, ensuring the air volume in the upper airflow duct 3a. When the airflow deflector 5 is in the second position, the airflow flows from the second end 532 to the first end 531 and then into the lower airflow duct 3b. Due to gravity, the airflow is more likely to flow into the lower airflow duct 3b. When the airflow passes through the ventilation gap 53, the flow velocity gradually decreases, thereby preventing the airflow from becoming too fast under the combined effects of gravity and the guidance of the ventilation gap 53, which would affect the user experience.

[0085] In some embodiments, the agitator 5 can move linearly to three positions, or it can rotate to switch between different positions; there is no limitation on this.

[0086] In some embodiments, combined with Figures 5 to 8 The turbulence assembly 5 is rotatable between the first position, the second position and the third position, and the rotation axes of the wind deflector 51 and the air guide 52 are set close to the first end 531.

[0087] By rotating around a fixed axis, the airflow deflector 5 can quickly switch between the first, second, and third positions, thereby achieving conversion between various modes such as single upward airflow, single downward airflow, and simultaneous bidirectional airflow. Without the need for complex multi-component linkages, only a single drive mechanism (such as a small motor) is required to complete the attitude adjustment, resulting in faster response and simpler operation logic. This allows users to quickly switch to the optimal airflow state according to the usage scenario (such as upward airflow during cooling and downward airflow during heating). Furthermore, the rotating connection ensures continuous attitude adjustment of the airflow deflector 5, allowing for precise control of the shielding area of ​​the baffle 51 and the guiding angle of the air guide 52 through fine-tuning, thus distributing the airflow direction. In addition, the rotation of the airflow deflector 5 occupies less space than linear movement, saving internal space in the indoor unit.

[0088] Furthermore, because the rotation axis is close to the first end 531 of the ventilation gap 53, the turbulence component 5 can achieve attitude adjustment with a shorter lever arm when switching positions. This not only reduces the load on the drive mechanism but also allows the turbulence component to switch quickly between the first, second, and third positions, reducing the response time for mode switching. When switching from bidirectional air supply (first position) to single downward air supply (second position), only a small rotation is needed to complete the obstruction of the upper air duct 3a by the wind deflector 51 and the guidance adjustment of the air guide 52, improving the convenience of operation and the energy efficiency of the entire machine.

[0089] In some embodiments, combined with Figure 5The wind deflector 51 is a straight plate, and the air guide 52 is an arc-shaped plate, that is... Figure 4 As shown in the cross section, the wind deflector 51 is straight and the air guide 52 is arc-shaped. The side of the air guide 52 facing the wind deflector 51 is a convex arc surface, and the side of the air guide 52 facing away from the wind deflector 51 and towards the air duct is a concave arc surface. It can cooperate with the arc surface of the front volute tongue 33 to guide the airflow.

[0090] The straight plate has a flat shielding surface. When the airflow deflector 5 is in the second position (shielding the upper airflow duct 3a) or the third position (shielding the lower airflow duct 3b), it can form a closer planar contact or a small gap fit with the inner wall of the airflow duct (such as the front volute 33), which can more effectively block the airflow compared to the arc-shaped structure. At the same time, the straight structure has stronger rigidity and is not easily deformed by airflow impact during long-term use, which can stably maintain the shielding effect and improve the reliability of the air supply mode.

[0091] Secondly, the air guide 52 of the curved plate can significantly optimize the smoothness and efficiency of airflow guidance. The curved surface design of the curved plate conforms to the natural flow trajectory of airflow, which can guide the airflow to smoothly turn along the curved surface, reducing airflow separation and turbulence caused by right angles or abrupt structures. When the turbulence component 5 is in the first position (bidirectional air supply), the curved air guide 52 can gently divert the airflow delivered by the fan 2 to the upper air duct 3a and the lower air duct 3b, reducing wind resistance loss; when in the second position (downward air supply), the curved surface can guide the airflow downward and form a more concentrated air supply direction; at the same time, the curved structure can make the airflow form a more stable wall-attached flow when passing through the ventilation gap 53, which, together with the acceleration effect of the gradual gap, further improves the air supply distance and coverage, and reduces energy loss caused by airflow diffusion.

[0092] Optionally, combined Figure 4 The housing 1 includes a front panel 14, an upper air outlet 121 is located at the upper end of the front panel 14, and a lower air outlet 122 is located below the front panel 14. The front panel 14 has a receiving groove 14a on the side facing the fan 2. The receiving groove 14a is configured to receive the wind deflector 51 when the turbulence component 5 is in the first turbulence position.

[0093] The receiving slot 14a on the front panel 14 facing the fan 2 provides storage space for the baffle 51 when the turbulence assembly 5 is in the first position (bidirectional air supply mode). This prevents the baffle 51 from occupying the effective airflow channel in the duct when it is in this position, reducing obstruction or compression of the airflow in the upper and lower air ducts 3b, allowing the airflow to be more smoothly distributed to the upper and lower air outlets 122, reducing wind resistance loss and improving air supply efficiency. At the same time, the precise positioning of the receiving slot 14a ensures that the baffle 51 forms a smooth transition with the surrounding structure when it is stored, avoiding airflow turbulence caused by component protrusion, and further reducing energy consumption.

[0094] Alternatively, the air guide 52 and the spoiler can be directly driven to rotate by the drive motor 61.

[0095] In some embodiments, combined with Figures 9 to 11 , Figure 9 This is a schematic diagram of the structure of the turbulence component 5 disclosed in the embodiments of this application. Figure 10 This is a schematic diagram of the drive motor 61, rotating shaft 62, and rotating base 63 disclosed in the embodiments of this application. Figure 11 for Figure 10 The enlarged view at point B shows that the wall-mounted air conditioner indoor unit 100 also includes a drive motor 61, a rotating shaft 62, and a rotating base 63. The rotating shaft 62 is located inside the air duct. The rotating base 63 is rotatably connected to the casing 1 via the rotating shaft 62. The wind deflector 51 and the air guide 52 are both connected to the rotating base 63. The drive motor 61 is connected to the rotating shaft 62, which drives the rotating shaft 62 to rotate, thereby driving the rotating base 63 to rotate, which in turn drives the air guide 52 and the wind deflector 51 to rotate together.

[0096] The wind deflector 51 and the air guide 52 are integrated into a single unit via the rotating base 63, rotating synchronously around the same axis 62. This avoids potential positional deviations or action delays that might occur due to independent movement. During mode switching, the wind deflector 51's obstruction of the air duct and the air guide 52's airflow guidance work precisely together. This ensures that in the second position, while the wind deflector 51 reliably blocks the upper air duct 3a, the air guide 52 simultaneously guides the airflow to the lower air duct 3b, reducing airflow leakage and improving the reliability of the air supply mode. Simultaneously, the structural strength of the rotating base 63 disperses the stress generated by airflow impact, reducing the risk of deformation of the wind deflector 51 or the air guide 52 due to long-term stress and extending the component's service life.

[0097] Secondly, the assembly process is simplified and maintenance costs are reduced. The wind deflector 51 and air guide 52 can be pre-assembled on the rotating base 63 before being installed as a whole onto the housing 1, reducing assembly steps and precision requirements within the air duct and improving production efficiency. During later maintenance, the entire airflow spoiler assembly 5 can be replaced by disassembling the rotating base 63, eliminating the need to individually adjust the position of the wind deflector 51 or air guide 52, thus reducing maintenance difficulty and time costs. Furthermore, this integrated design reduces the number of parts, helping to control the overall weight and manufacturing costs.

[0098] In some embodiments, the wall-mounted air conditioner indoor unit 100 further includes a plurality of connecting ribs 54, which are arranged at intervals along the length of the wall-mounted air conditioner indoor unit 100 and connected between the air guide 52 and the wind deflector 51 to enhance the connection strength between the air guide 52 and the wind deflector 51.

[0099] In some embodiments, combined with Figure 4 and Figure 6When the turbulence component 5 is in the first position, the air guide 52 includes a third end 521 and a fourth end 522 opposite to each other. The fourth end 522 is closer to the upper air outlet 121 relative to the third end 521. The first surface 331 includes a fifth end 3311 and a sixth end 3312 opposite to each other. The sixth end 3312 is closer to the upper air outlet 121 relative to the fifth end 3311. The distance between the third end 521 and the fifth end 3311 is greater than the distance between the fourth end 522 and the sixth end 3312.

[0100] Thus, when the turbulence component 5 is in the first position, when the airflow flows from the outlet side of the fan 2 to the upper air duct 3a, it must first pass through the fifth end 3311 of the front volute 33 and the third end 521 of the air guide 52, and then through the sixth end 3312 of the front volute 33 and the fourth end 522 of the air guide 52 before entering the upper air duct 3a. Due to gravity, the airflow is less likely to flow to the upper air duct 3a. When the airflow passes between the first air guide surface and the air guide 52, the flow velocity increases due to the reduced distance (i.e., the cross-sectional area of ​​the airflow channel is reduced), thereby enhancing the kinetic energy of the airflow. This allows the airflow to flow more forcefully to the upper air duct 3a after passing through the gap, reducing diffusion loss and increasing the air delivery distance and coverage of the airflow in the upper air duct 3a, thus ensuring the air volume in the upper air duct 3a.

[0101] In some embodiments, combined with Figure 7 , Figure 8 and Figure 12 , Figure 12 for Figure 7 In the enlarged view at point C, when the spoiler assembly 5 is in the second position, the minimum distance d between the end of the wind deflector 51 near the front volute 33 and the front volute 33 is 5mm to 8mm; when the spoiler assembly 5 is in the third position, the wind deflector 51 abuts against the volute 33.

[0102] When the spoiler component 5 is in the second position, if the gap is too small (less than 5mm), noise may be generated due to friction caused by component processing errors or vibration. Moreover, when the spoiler component 5 rotates from the second position to the third position, it may not be able to continue rotating due to the small gap. If the gap is too large (greater than 8mm), too much airflow will leak into the upper air duct 3a, weakening the airflow volume of the downward air supply mode. The minimum gap design of 5mm to 8mm between the wind deflector 51 and the front volute 33 takes into account both the shielding effect and the airflow stability. This gap can effectively block most of the airflow from entering the upper air duct 3a (ensuring that the air supply mode is mainly downward air supply) and avoid direct contact between the wind deflector 51 and the front volute 33.

[0103] The minimum distance d between the end of the wind deflector 51 near the front volute 33 and the front volute 33 can be 5mm-6mm, 6mm-8mm, 7mm-8mm, etc., with 5mm, 6mm, and 8mm being exemplary. Taking a minimum distance d of 6mm between the end of the wind deflector 51 near the front volute 33 and the front volute 33 as an example, when the deflector 5 is in the second position, it can effectively block most of the airflow from entering the upper air duct 3a (ensuring that the air supply mode is mainly downward airflow) and avoid direct contact between the wind deflector 51 and the front volute 33.

[0104] In some embodiments, when the spoiler assembly 5 is in the first position, the fifth end 3311 is located above the bottom tangent line L of the front volute 33; when the spoiler assembly 5 is in the second position, the wind deflector 51 is located above the bottom tangent line L of the front volute 33, and the air guide 52 is located below the bottom tangent line of the front volute 33.

[0105] When the airflow exits from the outlet side of the fan 2, it will be blown out along the tangent at the bottom of the front volute 33. When the turbulence component 5 is in the first position, it prevents the air guide 52 from guiding too much airflow to the upper air duct 3a and too little airflow to the lower air duct 3b, ensuring that the airflow distribution in the upper and lower air ducts 3b is uniform. When it is in the second position (downward airflow), the wind deflector 51 is located above the tangent and can effectively block the upward airflow path. When the airflow is blown out along the tangent direction, the wind deflector 51 can block the upper air duct 3a as much as possible. The air guide 52 is located below the tangent and can naturally receive and guide the airflow downward, making the airflow more concentrated and flowing to the lower air outlet, thus enhancing the downward airflow capacity.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
