Description

Technical Field

[0001] This invention belongs to the field of air conditioning accessories technology, specifically relating to an adjustable displacement air guide device suitable for wall-mounted, cabinet-type, cylindrical, and central air conditioning outlets. It provides an innovative system solution to problems such as direct airflow causing illness, inconvenient installation, cumbersome operation, and impact on air conditioning operation. Background Technology

[0002] With global warming and improved living standards, air conditioning has become an indispensable appliance in homes and offices. However, the health problems caused by direct exposure to cold air from air conditioners are becoming increasingly serious, especially for the elderly, children, pregnant women, and those with weaker constitutions. Direct exposure to cold air can lead to a range of symptoms associated with air conditioning, such as colds, headaches, joint pain, and facial paralysis; in severe cases, it can even trigger cardiovascular and cerebrovascular diseases. The number of people seeking medical attention each year due to direct exposure to air conditioning remains high, placing a heavy burden on families and social medical insurance.

[0003] Various air conditioner deflector products have appeared on the market in an attempt to solve the problem of direct cold air blowing, but these products generally suffer from six long-standing technical defects.

[0004] First, the installation methods are outdated, making them prone to detachment and damage to the air conditioner. Traditional wind deflectors are mostly fixed to the air conditioner unit using adhesive or hooks. Adhesive is prone to aging and failure under alternating hot and cold environments, and a sudden detachment of the wind deflector could injure people or objects below. Hook-type installation requires inserting metal hooks into the air conditioner's vent, which can easily damage the internal fan blades and air guide plates, causing the fan blades to jam, deform, or even damage the motor. Some products require drilling for installation, causing permanent damage to the air conditioner unit.

[0005] Secondly, obstructing the air intake severely impacts the air conditioner's cooling and heating efficiency. Many air deflectors are designed to be too large to maximize coverage, obstructing not only the air outlet but also partially or completely blocking the air intake. With the air intake blocked, the return air volume decreases sharply, significantly reducing the evaporator's heat exchange efficiency, resulting in poorer cooling and heating performance and increased power consumption. In severe cases, it can even cause evaporator icing, compressor liquid slugging, and other malfunctions, significantly shortening the air conditioner's lifespan.

[0006] Third, the airflow guidance structure is too simple, resulting in high wind resistance and significant airflow loss. Existing air deflectors are mostly single-layer flat panels with several uniformly spaced small holes on their surface. Airflow passing through these holes generates considerable flow resistance, significantly reducing the output airflow. To reach the set temperature, the air conditioning compressor needs to run for a longer period, further increasing energy consumption. A single-layer flat panel cannot effectively manage and soften the airflow; although the airflow direction changes, there is still a strong, concentrated airflow, failing to truly achieve a gentle breeze effect.

[0007] Fourth, the control method is outdated and extremely inconvenient to use. Traditional wind deflectors are fixed in position after installation and cannot be flexibly adjusted according to usage needs. When it is not necessary to prevent direct airflow—for example, when heating in winter requires warm air to blow directly onto the ground, when the room needs to be cooled quickly, or when no one is in the room—the wind deflector cannot be quickly moved away. Users must climb up to manually disassemble it, which is extremely inconvenient, and frequent disassembly accelerates fatigue damage to the installation structure.

[0008] Fifth, it has extremely poor versatility; a single product cannot be adapted to multiple models. The shapes and sizes of the air outlets of wall-mounted units, floor-standing units, cylindrical air conditioners, and central air conditioners vary greatly, requiring users to purchase different products separately, increasing usage costs and making selection more difficult.

[0009] Sixth, safety, durability, and aesthetics are insufficient. Many cheap wind deflectors use flammable materials, posing a fire hazard. Prolonged exposure to alternating hot and cold environments can cause the materials to age, discolor, become brittle, and crack. The rough design results in them clashing with the air conditioner unit after installation, detracting from the home's aesthetics.

[0010] In summary, existing air conditioning deflector products have long suffered from six core pain points: easy detachment and damage to the air conditioner during installation, obstruction of air inlet affecting efficiency, simple air guiding structure with high wind resistance, outdated operation and inconvenience, extremely poor versatility, and insufficient safety. There is an urgent need for a new generation of air conditioning deflector devices that completely reconstruct the entire chain from installation method, air guiding structure, transmission control to safety assurance.

III. Summary of the Invention 3.1 Purpose of the Invention The purpose of this invention is to provide a new generation of universal adjustable displacement air guide device for air conditioners, based on non-destructive fixing, driven by modular displacement transmission, centered on multi-layer independent sliding gentle airflow, and controlled by a dual-mode intelligent control system. It completely eliminates the need for adhesive hook installation. It fundamentally changes the single-layer flat air guide structure, achieving multi-level gentle airflow adjustment through three layers of independent sliding staggered deflection, resulting in gentle and uniform airflow with minimal reduction in air volume. It completely overturns manual fixed control, using motor drive, position memory, and infrared learning to achieve one-button switching of air guide modes. It achieves universal compatibility with all models, protecting public health and preventing air conditioning-related illnesses at their source.

[0021] 3.2 The Formation Process of Technical Ideas and Underlying Design Principles Step 1: Starting with health concerns – Why direct cold air can be a health hazard The inventor's initial motivation stemmed from concern for his family's health. Elderly family members and young children frequently experienced colds, headaches, and joint pain due to direct exposure to cold air from air conditioners. The inventor, after reviewing medical literature, discovered that the harm caused by direct airflow from air conditioners far exceeds common perceptions: direct exposure to the face can cause facial nerve spasms or even facial paralysis; direct exposure to the head can induce migraines and cerebral vasoconstriction; direct exposure to the neck and shoulders can worsen cervical spondylosis and frozen shoulder; direct exposure to the abdomen can cause gastrointestinal disorders; and direct exposure to joints can induce or aggravate arthritis. Every summer, hospitals see a surge in patients seeking treatment for facial paralysis, upper respiratory infections, and joint pain caused by direct airflow from air conditioners. These illnesses can largely be prevented by improving the way air conditioners circulate.

[0022] The inventors thus established the core design goal: the air conditioner must deliver a gentle, even breeze that doesn't blow directly onto the body, while maintaining its cooling and heating efficiency. This is not just a matter of comfort, but a matter of vital importance concerning the health of hundreds of millions of Chinese people.

[0023] Step Two: Structural Reflection on Existing Wind Deflectors – Why They Don't Work Well The inventors conducted systematic testing and analysis of various commercially available wind deflectors. Adhesive-backed wind deflectors experience rapid aging of the adhesive under alternating hot and cold conditions, posing a high risk of detachment. Hook-type wind deflectors require inserting metal hooks into the air outlet, easily colliding with the fan blades. More seriously, many wind deflectors obstruct the air conditioner's air intake, leading to insufficient return air and a sharp drop in cooling efficiency. Single-layer flat-plate air guide structures simply block the airflow and direct it in one direction, resulting in a strong, concentrated airflow at the outlet, but with high wind resistance and significant airflow loss. These products all share a common problem: they merely block, not guide. They block the airflow, but create new problems—reduced airflow, lower efficiency, complex installation, and inconvenient operation.

[0024] Step 3: Multi-layered staggered sliding soft wind – a breakthrough in principle from wind blocking to wind guiding. Starting from the principles of fluid mechanics, the inventors rethought the essence of airflow softening. To soften airflow, it's not simply about blocking it, but about allowing it to undergo multiple deflections and diffusions, converting concentrated dynamic pressure into uniform static pressure, and then slowly releasing it in a large-area diffused form. Based on this principle, the inventors designed a multi-layered independent sliding composite air guide plate structure. Each of the three layers has holes at different positions and diameters. When the three layers are perfectly aligned, the airflow passes in a straight line, in direct blowing mode. When the layers are relatively staggered and sliding, the airflow is deflected layer by layer, undergoing multiple changes in direction, significantly reducing the flow velocity, and evenly dispersing the air pressure. This multi-layered staggered sliding structure, by changing the length and number of deflection paths between the layers, achieves multi-level stepless adjustment from direct blowing to strong anti-direct blowing. Most importantly, the total air outlet area does not decrease throughout the entire process; only the dynamic pressure of the airflow is converted into static pressure, so the total air volume remains essentially unchanged, ensuring the cooling and heating efficiency of the air conditioner.

[0025] Step 4: Sliding adjustment mechanism of the three-layer plate The sliding adjustment mechanism of the three-layer plate is the core innovation of this invention. In the normal off-state, all three layers are closed, with the outermost layer featuring fine louvers that match the original seal of the air conditioner, maintaining the overall aesthetics and making any added device invisible when the unit is off. When the user requires a gentle breeze, the inner layer slides down alone, exposing the middle layer's large holes and the outer layer's diffuser holes. Both layers work together, increasing the airflow area while maintaining a moderate wind speed due to the two deflections – this is the center-slit airflow guiding mode. When the user requires a larger airflow, the middle layer continues to slide down, leaving only the outer layer's large-hole diffuser plate in operation. The airflow is dispersed through the single large hole, maximizing the airflow – this is the large-vent direct-blow mode. When all three layers are closed, the entire air guide plate acts as a wind tongue, swaying up and down with the original air conditioner's fan blades to achieve guided airflow. The airflow direction is controlled by the fan blades; the air guide plate itself does not obstruct or alter the airflow path. Logically, the system does not allow all three layers to slide down completely to avoid meaningless redundant actions.

[0026] Step 5: Three-layer sealing structure To ensure a gentle breeze effect, the sides and interlayers of the three-layer panels are sealed using a sliding rail structure. The rails engage the sides of each layer, and as the panels move along the rails, their sides fit tightly against the rail groove walls, forming a sealed surface. The three layers are tightly stacked within the rail grooves, with a similar seal between each layer. This structure ensures that airflow can only pass through the openings on each layer's surface, following the designed path of inner layer combing, middle layer pressure equalization, and outer layer diffusion before being blown out, preventing leakage from the panel seams and guaranteeing that the multi-stage gentle breeze effect is not compromised.

[0027] Step 6: Scenario-specific design of fixed mechanisms The inventors designed the most suitable fixing solutions for two completely different usage scenarios: the original equipment market and the aftermarket.

[0028] Original equipment manufacturer (OEM) parts: Utilizes a top-and-bottom support snap-fit ​​structure. The upper hook only engages with the upper edge of the air outlet frame, without extending into the air cavity or touching the fan blades. The lower support and upper hook exert force against each other, with length adjustment and automatic locking achieved via a threaded self-locking adjustment rod. Installation requires no tools; simply tighten manually. This achieves a non-destructive installation without drilling, adhesive, entering the air cavity, or touching the fan blades.

[0029] Aftermarket – Self-installation by Existing Air Conditioner Users: The inventor analyzed the installation form of wall-mounted air conditioners – the unit is hung on the wall, with all four sides fitting against the wall, leaving a gap between the unit and the wall. Based on this structural feature, the inventor designed a two-way constraint fixing scheme with a bottom insert and a side wrap-around design. The bottom uses a thin steel or hard plastic sheet inserted into the gap between the unit and the wall, utilizing the clamping force of the gap to provide outward support and counteract the outward pushing force of the air conditioner's airflow on the air guide plate. The side uses a wrap-around structure to hold the air conditioner unit from both sides, providing downward constraint and counteracting the weight of the air guide plate itself and the force of downward sliding. The two-way constraints work together, making installation extremely simple, tool-free, and without damaging the unit, while fully complying with the principles of mechanical constraint. The bottom insert is made of a composite material of thin steel, hard plastic, or hard plastic covered with metal, with a thickness adaptable to the gap width of different models, allowing the air conditioner unit to be slightly lifted before insertion into the gap. Aftermarket solutions such as cabinet air conditioners and cylindrical air conditioners, due to their diverse models and varying air outlet shapes, may employ adjustable clips or steel sheet bending structures, depending on the specific model, and are not limited to the scope of this invention.

[0030] Step 7: Modular Displacement Transmission – One core module adapts to all models Air conditioners from different brands and models vary greatly in the shape, size, and position of their air outlets. Traditional air guide products can only be adapted to a single model. The inventors adopted a modular design approach: designing core drive components such as micro-gear motors, gear sets, and position sensors into a unified standard module. For different models such as wall-mounted, floor-standing, cylindrical, and central air conditioning units, only external transmission adapters such as slide rails, shafts, and telescopic arms need to be replaced. The core module remains unchanged, while external adapters can be flexibly replaced, achieving universal compatibility across all models. Mechanical limit is achieved by setting stop blocks at both ends of the slide rail, motor stall protection determines the end of the stroke by detecting the motor's operating current, and position memory records the stroke position through Hall sensors or potentiometers, ensuring that the air guide plate can accurately reach the preset position.

[0031] Step 8: Dual-mode intelligent control – making it easy for everyone to use. To cater to the usage habits and needs of different user groups, the inventor designed a dual-mode control scheme. The original factory-installed mode is suitable for air conditioner manufacturers, allowing the control module to be directly integrated into the air conditioner's mainboard for seamless operation using the original remote control. The aftermarket universal mode is suitable for users who have already installed air conditioners. Utilizing infrared learning functionality, it can learn and simulate the infrared signals of any brand of air conditioner remote control, achieving perfect compatibility with the original remote. Both modes require no additional remote control and eliminate the need for manual operation from heights, making them easy for the elderly and children to use.

[0032] 3.3 Core Structure 3.3.1 Fixed Mechanism Fixed structures are configured separately for the original equipment market and the aftermarket.

[0033] The original market fixing mechanism adopts a symmetrical top-and-bottom support snap-fit ​​structure. Each side of the fixing mechanism includes an upper hook, a lower support, a threaded self-locking length adjustment rod, an anti-slip soft rubber pad, and a lateral anti-slip limiting boss. The upper hook is a hook-shaped metal or high-strength engineering plastic component with the hook facing downwards. It only hooks onto the upper edge of the air conditioner's air outlet frame, without entering the air cavity or touching the fan blades, air guide plates, or any moving parts inside the air conditioner. The lower support is arranged opposite the upper hook, located below it. The top of the lower support has an anti-slip soft rubber pad to increase friction with the air conditioner panel and protect the panel from scratches. The lower support has a threaded self-locking length adjustment rod inside; rotating the adjustment rod changes the extension length of the lower support. The thread uses a self-locking design, automatically locking after adjustment and preventing loosening due to vibration. The lateral anti-slip limiting boss is located on both sides where the fixing mechanism contacts the air conditioner's outer frame to limit the device's lateral movement. During installation, first hang the upper hook on the upper edge of the air outlet, then rotate the threaded adjusting rod of the lower support to extend it downwards and press it against the lower edge of the air conditioner panel. The upper hook and lower support form a counterforce, and the entire device is firmly fixed to the air conditioner body. No drilling, adhesive, or tools are required throughout the process.

[0034] The mounting mechanism for aftermarket wall-mounted air conditioners employs a two-way constraint structure: a bottom insert and side clamping. The bottom insert is a thin, sheet-like component made of thin steel sheets, hard plastic sheets, or a composite material of hard plastic-coated metal sheets, with a thickness ranging from 0.3 mm to 0.8 mm, adaptable to the gap width between the wall-mounted unit and the wall. During installation, the bottom insert is inserted into the gap between the unit and the wall. Slightly lifting the air conditioner unit allows the insert to be positioned, where it is held in place by the gap, providing outward support to counteract the outward pushing force of the airflow onto the air guide plate. The side clamping structure consists of locking arms extending from both sides of the air guide plate, gripping the air conditioner unit from both sides and providing downward constraint to counteract the weight of the air guide plate itself and the force of downward sliding. The bottom insert counteracts the airflow thrust, while the side clamping counteracts gravity and sliding forces; the two directions work together to ensure a stable installation without any tools. Aftermarket solutions such as cabinet air conditioners and cylindrical air conditioners, due to their diverse models and varying air outlet shapes, may employ adjustable clips or steel sheet bending structures, depending on the specific model, and are not limited to the scope of this invention.

[0035] 3.3.2 Displacement Transmission Mechanism The displacement transmission mechanism is responsible for driving the air guide plates to switch precisely between preset positions. The mechanism adopts a modular design and consists of a core drive module and external transmission adapters.

[0036] The core drive module uses standardized components, including a miniature silent geared motor, a precision gear set, a position sensor, and drive circuitry. The miniature silent geared motor provides the driving force with extremely low operating noise. The precision gear set converts the motor's high-speed rotation into low-speed, high-torque output, ensuring smooth movement of the air guide vane. The position sensor uses a Hall effect sensor or potentiometer to detect the current position of the air guide vane in real time, achieving precise position memory.

[0037] External drive adapters can be flexibly replaced according to the air conditioner model. Wall-mounted air conditioners are equipped with upper and lower sliding rail modules, cabinet air conditioners with left and right sliding rail modules, cylindrical air conditioners with rotating modules, and central air conditioners with telescopic modules. The core drive module and external drive adapters are connected through standardized interfaces, making replacement convenient.

[0038] The transmission mechanism is equipped with dual safety protection: mechanical limit and motor stall protection. Mechanical limit is achieved by setting stop blocks at both ends of the slide rail to prevent the air guide plate from exceeding the preset stroke. Stall protection determines the stroke end point by detecting the motor's operating current—when the air guide plate reaches its limit position and is blocked by the stop block, the motor current rises sharply. The drive circuit detects that the current exceeds a set threshold and automatically cuts off the motor power supply to prevent motor overload damage.

[0039] 3.3.3 Multi-layer composite air guide plate The multi-layer composite air guide plate is the core and original component of this invention. It consists of three independent plates stacked together: an inner directional louvered air guide layer, a middle large-hole air distribution layer, and an outer gradient diffusion layer. Each plate can slide independently laterally, and the position and diameter of the openings on each plate are different.

[0040] Inner directional louvered airflow guide layer: On the side facing the air conditioner outlet, directional louvered airflow guide channels are opened on the panel. Its function is to initially sort out the raw airflow blown out by the air conditioner, organize the chaotic airflow into an orderly airflow with a unified direction, and at the same time reduce vortex noise.

[0041] Middle layer with large pores for air distribution: Located between the inner and outer layers, this layer has large-diameter through-holes. Its function is to evenly distribute the airflow that has passed through the inner layer, ensuring uniform airflow across the entire surface and preventing localized airflow concentration.

[0042] Outer Gradient Diffusion Layer: On the side facing the interior, the panel features gradient diffusion holes. These holes can be round, square, elongated, or gradually tapered from larger to smaller. Their function is to slowly release the airflow, which has passed through the middle layer for pressure equalization, into the room in a diffused manner, achieving a gentle, windless breeze effect.

[0043] The three-layer panel is sealed on both sides and between layers via a sliding rail structure. The sliding rail engages the sides of each layer, and as the panel moves along the rail, its sides fit tightly against the rail groove wall, forming a sealing surface. The three layers are tightly stacked within the rail groove, with a similar seal between each layer. This structure ensures that airflow can only pass through the openings on each layer's surface, following the designed path of inner layer combing, middle layer pressure equalization, and outer layer diffusion before being blown out, preventing leakage from the panel seams and ensuring that the multi-stage gentle breeze effect is not compromised.

[0044] The sliding adjustment mechanism of the three-layer panel is as follows: In the normal off-state, all three layers are closed, with the outermost layer featuring fine louvers that match the original seals of the air conditioner, maintaining the overall aesthetics and making any added device invisible when the unit is off. When the inner layer slides down alone, the middle layer with large holes and the outer layer with diffuser holes are exposed. Both layers work together, increasing the air outlet area, but the airflow is moderately velocities due to the two deflections; this is the center-seam airflow guiding mode. When the middle layer continues to slide down until only the outer layer with large holes remains operational, the airflow is dispersed through a single layer of large holes, maximizing the air volume; this is the large-outlet direct-blow mode. When all three layers are closed, the entire air guide plate acts as a wind tongue, swaying up and down with the original air conditioner fan blades to achieve guided airflow. The airflow direction is controlled by the fan blades; the air guide plate itself does not obstruct or alter the airflow path. Logically, the system does not allow all three layers to slide down completely to avoid meaningless redundant actions.

[0045] The air guide plate can be quickly disassembled and washed; it can be installed and removed with a simple rinse. The sides can be flexibly configured with either sealed edges or small air vents to suit the shape of the air conditioner, its placement, and the manufacturer's requirements, enabling side-discharge or directional airflow, thus enhancing versatility and aesthetics.

[0046] 3.3.4 Control Module The control module supports dual-mode control, covering both original equipment and aftermarket upgrade application scenarios.

[0047] Original factory built-in mode: The control module is directly integrated into the air conditioner's main board, deeply integrated with the air conditioner's electronic control system. Users can directly control the movement of the air deflector and switch airflow modes using the original air conditioner remote control, with an operating experience completely consistent with the air conditioner's original functions.

[0048] Aftermarket Universal Mode: The control module has a built-in infrared learning chip and infrared transceiver. Upon initial use, the user simply points the original air conditioner remote control at the infrared receiver window of the control module and presses the corresponding button. The control module then learns and stores the infrared code of that button. After learning, the control module can simulate the original remote control signal to remotely control the movement of the air deflector. This mode requires no additional remote control equipment, is compatible with various brands of air conditioners, and is easy to operate.

[0049] 3.3.5 Power Supply Module The power supply module corresponds one-to-one with the two control modes mentioned above.

[0050] Original factory built-in mode: Powered directly by the air conditioner's main board, no separate power supply required.

[0051] Aftermarket Universal Mode: Utilizes independent, low-power dry cell batteries. The battery compartment features a built-in reverse connection protection circuit, preventing circuit damage even if the batteries are installed incorrectly. Integrated overcurrent protection automatically cuts off power when the motor stalls. A low battery warning function is included; an indicator light flashes to prompt replacement when the battery is low. This independent power supply eliminates the need for power from the air conditioner or an external power adapter, eliminating potential circuit safety hazards. The low-power design ensures long battery life.

[0052] 3.4 Working Principle When installing an aftermarket wall-mounted air conditioner, insert the bottom insert into the gap between the unit and the wall, slightly lift the unit to position the insert, and then secure the side-mounted structure to the unit from both sides. No tools are required throughout the installation. For OEM installation, hang the upper hooks of the dual-side fixing mechanisms on the upper edge of the air conditioner's air outlet frame, and rotate the threaded adjustment rod of the lower support to tighten it against the lower edge of the air conditioner panel.

[0053] In daily use, users can switch operating modes with a single button on the remote control. In the center-seam airflow mode, the inner layer moves downward, and the airflow is deflected by the middle and outer layers before being blown out at a moderate speed. In the large-vent direct-blow mode, the middle layer continues to move downward, leaving only the outer large-perforation diffuser plate in operation, maximizing the airflow. In the follow-up airflow mode, all three layers are closed, and the entire panel acts as a fan, oscillating up and down following the original air conditioner fan blades. The system logic does not allow all three layers to move downward. The sides and interlayers of the three layers are sealed, and airflow only passes through the openings on the panel surface, with no side leakage.

[0054] The air guide plate's position is precisely memorized by a position sensor, automatically resetting to the user-set mode each time the device is turned on. The air guide plate can be quickly removed and washed, making daily cleaning convenient.

[0055] 3.5 Beneficial Effects First, it protects health and prevents air conditioning sickness. The multi-layered, staggered, sliding soft-wind structure transforms the concentrated, high-pressure airflow from the air conditioner's output into a uniform, diffused soft breeze, eliminating the harmful effects of direct cold air blowing on the body at the source. It effectively prevents symptoms of air conditioning sickness such as facial paralysis, headaches, joint pain, and upper respiratory tract infections caused by direct air conditioning blasts. With minimal device cost, it protects the health of hundreds of millions of people, reduces medical expenses, and alleviates the pressure on social medical insurance.

[0056] Secondly, it offers non-destructive universal installation. The original market's top and bottom support clip structure allows for non-destructive installation without drilling, adhesive, entering the air cavity, or touching the fan blades. Aftermarket wall-mounted units use a bottom insert and side-mounted bi-directional constraint structure, making installation extremely simple and conforming to mechanical constraints. It is compatible with all wall-mounted, cabinet, cylindrical, and central air conditioning models.

[0057] Third, it adapts to all types of displacement. The modular design and universal core drive module allow it to adapt to various motion modes such as sliding up and down, translating left and right, rotating, and telescopic by simply replacing the external transmission adapter.

[0058] Fourth, it features three independent sliding multi-level gentle airflow adjustment. It offers three modes: center seam air guide, large air vent direct blowing, and follow-up fan tongue. The three layers are sealed on both sides and between each layer, ensuring no side leakage of airflow. The total air volume remains essentially unchanged, guaranteeing the air conditioner's cooling and heating efficiency. When the unit is off, the three layers close together, maintaining the same appearance as the original seals and not affecting the overall aesthetics.

[0059] Fifth, dual-mode intelligent control. The original factory-built-in control can be directly integrated with the air conditioning electronic control system, while the aftermarket version is compatible with various brands of original remote controls via infrared learning. One-button mode switching eliminates the need for manual operation from heights. It also features a position memory function that automatically restores position after power failure.

[0060] Sixth, safe and reliable. The entire unit uses V0-grade flame-retardant materials, with dual safety protection including mechanical limit switches and motor stall protection. The dry battery power supply solution features reverse connection protection, overcurrent protection, and low battery warning, eliminating any potential electrical safety hazards.

[0061] Seventh, aesthetically pleasing and easy to clean. The ultra-thin, integrated design blends seamlessly with the air conditioner's appearance after installation. The air guide plate is quick-removable and washable; it can be installed and removed easily with a simple rinse.

[0062] Eighth, the structure is simple and the cost is controllable.

Detailed Implementation

[0065] Example 1: Post-installation application of wall-mounted air conditioners This embodiment is adapted for installed household wall-mounted air conditioners. The fixing mechanism adopts a two-way constraint structure with a bottom insert and a side wraparound design. The bottom insert is made of thin steel or hard plastic sheet with a thickness of 0.3 mm to 0.8 mm, which is inserted into the gap between the wall-mounted unit and the wall to provide outward support and counteract the airflow thrust. The side wraparound structure fastens the air conditioner body from both sides, providing downward constraint. The two directions work together to constrain the unit, making installation extremely simple, tool-free, and without damaging the unit.

[0066] The displacement transmission mechanism uses an upper and lower sliding rail module, with the core drive module driving each layer to move up and down along the rails. In the center-seam airflow mode, the inner layer moves downward; in the large-vent direct-blow mode, the middle layer continues to move downward; and in the follow-up airflow mode, all three layers close together and oscillate with the original fan blades. When the unit is off, all three layers close together, and the appearance is consistent with the original seal of the air conditioner. The sides and interlayers of the three layers are sealed by the sliding rails, and airflow only passes through the openings on the panel surface. All three layers of the air guide plate use circular gradient diffuser holes, with the outer layer holes having a larger inner diameter and a smaller outer diameter. The control module adopts a retrofit universal mode and uses an infrared learning original remote control. The power supply module is powered independently by dry batteries. The entire unit is made of V0-grade flame-retardant material, and the air guide plate is removable and washable.

[0067] Example 2: Application of cabinet air conditioners This embodiment is adapted for floor-standing air conditioners. Original equipment manufacturers (OEMs) use a top-and-bottom support snap-on fixing mechanism. The displacement transmission mechanism uses left and right sliding rail modules, allowing each shelf to slide left and right. The airflow mode switching logic is the same as in Embodiment 1. All three shelves use a long, perforated, gradually diffusing structure. The control module can be the original factory built-in mode, directly integrating the air conditioner's mainboard. Aftermarket floor-standing units, due to their diverse models and varying air outlet shapes, can use adjustable snap-on or steel sheet bending structures, depending on the specific model.

[0068] Example 3: Application of Cylindrical Air Conditioner This embodiment is adapted for cylindrical vertical air conditioners. The displacement transmission mechanism adopts a rotary module, and the air guide plate can rotate around the cylindrical body. In the center seam air guide mode, the inner layer plate rotates and moves laterally; in the large air outlet direct blowing mode, the middle layer plate continues to move laterally. Small air guide holes can be set on both sides of the air guide plate to achieve a side air outlet effect. The rear-mounted solution is the same as in Embodiment 2, and the specific installation structure depends on the model.

[0069] Example 4: Central Air Conditioning Application This embodiment is adapted to the ceiling air outlet of a central air conditioning system. The displacement transmission mechanism adopts a telescopic module, and the air guide plate can extend downwards or retract upwards. The air guide mode switching logic is the same as in Embodiment 1. All three layers of the air guide plate adopt a large-aperture uniform airflow and gradual diffusion structure.

[0070] Example 5: Upgrading Existing Air Conditioners via Retrofitting Users who have already installed air conditioners can purchase a generic aftermarket version separately. Wall-mounted units use a bottom-mounted insert and side-mounted design, requiring no tools and can be installed manually. Floor-standing and cylindrical units use adjustable clips or bent steel sheets; the specific structure depends on the model. The control module learns the original remote control's infrared signal, allowing for one-button mode switching. The power module uses independent dry-cell batteries, eliminating the need for an external power source. Different sizes of air guide plates are available upon request depending on the air conditioner model.

Claims

1. A universal adjustable displacement air guide device for air conditioning, characterized in that, The system includes a fixing mechanism, a displacement transmission mechanism, and an air guide plate. The fixing mechanism is configured for the original equipment market (OEM) and the aftermarket: the OEM market uses an upper and lower top support snap-fit ​​structure, where the upper hook only hooks onto the upper edge of the air outlet frame, and the lower support and upper hook are supported against each other, with a threaded self-locking adjustment and automatic locking; the aftermarket wall-mounted unit uses a two-way constraint structure with a bottom insert and side wrapping, where the bottom insert is inserted into the gap between the wall-mounted unit and the wall to provide outward support, and the side wrapping structure fastens the air conditioner body from both sides to provide downward constraint. For cabinet and cylindrical units, the aftermarket solution uses an adjustable snap-fit ​​or steel sheet bending structure, depending on the model. The displacement transmission mechanism drives the air guide plate to switch between preset positions. The air guide plate is a multi-layer independent sliding composite structure, where each layer can slide relatively independently, achieving multi-level airflow adjustment by changing the airflow path between the layers.

2. The apparatus according to claim 1, characterized in that, The air guide plate is composed of three independent plates stacked together: an inner directional louvered air guiding layer, a middle large-hole air distribution layer, and an outer gradient diffuser layer. The position and diameter of the openings on each plate are different. The sides and interlayer of the three plates are sealed, and the airflow can only pass through the openings on the surface of each plate. In the normal shutdown state, all three plates are closed, and the outermost layer has fine louvered holes. When the inner plate slides alone, it is in the center-slit air guiding mode. When the middle plate continues to slide and only the outer layer is working, it is in the large air outlet direct blowing mode. When all three plates are closed, the entire plate acts as a wind tongue and swings with the original air conditioner fan blades. The system logic does not allow all three plates to move downwards.
