Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an outdoor unit air conditioner and its control method. Background Technology

[0002] As people's demands for quality of life and comfort continue to rise, air conditioners, as important household appliances, are receiving increasing attention from consumers. However, traditional air conditioner outdoor units, due to their prolonged exposure to the outdoor environment, are prone to accumulating dust, dirt, and other pollutants, leading to reduced heat exchange efficiency and even affecting the normal operation of the air conditioner. Furthermore, cleaning the outdoor unit usually requires professional maintenance personnel, increasing maintenance costs for users and causing inconvenience.

[0003] In existing technologies, most air conditioner outdoor unit designs do not consider convenient cleaning methods. Users often need to disassemble multiple parts to clean the outdoor unit, a cumbersome and time-consuming process. Moreover, some outdoor unit designs lack reasonable protective measures, which may prevent the unit from being fully restored to its optimal working condition after cleaning. This is especially true for air outlet components such as fan blades and blowers in the outdoor unit. If they are not properly repositioned, it can cause dynamic imbalance, resulting in severe vibrations, affecting the lifespan of the equipment and the user experience. Therefore, how to make it convenient for users to clean the air outlet components of the outdoor unit, thereby improving the efficiency of the air conditioner and extending its service life, has become an urgent problem to be solved. Summary of the Invention

[0004] The present invention provides an outdoor unit air conditioner and a control method, which aims to solve the problem of difficult cleaning of the air outlet assembly of the outdoor unit air conditioner under the prior art.

[0005] In a first aspect, the present invention provides an outdoor unit air conditioner, comprising: a body assembly; an air outlet assembly disposed above the body assembly, the air outlet assembly being used to exchange gases inside and outside the body assembly; and a lifting assembly connecting the body assembly and the air outlet assembly, the lifting assembly driving the air outlet assembly to lift and separate or lower and engage relative to the body assembly.

[0006] Secondly, the present invention provides an outdoor unit air conditioner control method, applied to the outdoor unit air conditioner as described above, comprising: acquiring the cleanliness status inside the outdoor unit air conditioner; issuing a cleaning requirement warning to the user when the cleanliness status reaches a cleanliness threshold; receiving a cleaning mode start command input by the user, and controlling the lifting component to lift the air outlet component to separate the air outlet component from the body component; receiving a cleaning mode end command input by the user, and controlling the lifting component to lower the air outlet component to reconnect and reset the air outlet component with the body component.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] In the technical solution of the present invention, by connecting the air outlet component to the lifting component located above the body component, the lifting component enables the lifting separation and lowering engagement between the air outlet component and the body component, so that the air outlet component and the body component in which the air outlet component is installed can have sufficient cleaning operation space, thereby making it easier to clean.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0026] To address the difficulty in cleaning the air outlet assembly 2 of an outdoor unit air conditioner in the prior art, this invention proposes an outdoor unit air conditioner and its control method, referring to... Figures 1 to 9The outdoor unit air conditioner of this invention includes: a body assembly 1; an air outlet assembly 2, disposed above the body assembly 1, used for exchanging air between the inside and outside of the body assembly 1; and a lifting assembly 3, connecting the body assembly 1 and the air outlet assembly 2, which drives the air outlet assembly 2 to rise or fall relative to the body assembly 1 for separation or engagement. The body assembly 1 is the main structural unit of the outdoor unit air conditioner, typically containing key components such as a heat exchanger, compressor, and heat dissipation pipes. The air outlet assembly 2, powered by a fan blade 23, drives airflow and is disposed above the body assembly 1, responsible for discharging or introducing processed air into the outside. The lifting assembly 3 connects the body assembly 1 and the air outlet assembly 2, and uses hydraulic or mechanical devices to raise and lower the air outlet assembly 2, thereby achieving separation and engagement of the air outlet assembly 2 relative to the body assembly, facilitating cleaning and maintenance of the outdoor unit. In this embodiment of the invention, the outdoor unit air conditioner elevates the air outlet assembly 2 via a lifting component 3. This provides sufficient operational space between the unit body assembly 1 and the fan assembly 22 after separation by the lifting component 3, allowing users to easily perform cleaning and maintenance. This reduces the risk of reduced heat exchange efficiency due to dust accumulation on the outdoor unit. The overall structure and operation are simple. After separation by the lifting component 3, users can perform routine maintenance without professional knowledge, improving the user experience. Furthermore, thorough cleaning enhances the air conditioner's performance, convenience, and durability. It also improves the adaptability of the outdoor unit air conditioner to specific environments, such as different installation locations or climatic conditions, making it more versatile.

[0027] Compared with the prior art, in the embodiments of the present invention, by connecting the air outlet assembly 2, which is set above the body assembly 1, to the lifting assembly 3, the lifting assembly 3 enables the lifting separation and lowering engagement between the air outlet assembly 2 and the body assembly 1, so that the air outlet assembly 2 and the interior of the body assembly 1 where the air outlet assembly 2 is installed can have sufficient cleaning operation space, thus making it easier to clean.

[0028] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 4 , Figures 6 to 8The lifting assembly 3 includes a hydraulic device 31 and at least one telescopic hydraulic rod 32. The two ends of the telescopic hydraulic rod 32 are connected to the body assembly 1 and the air outlet assembly 2, respectively. The hydraulic device 31 connects to the telescopic hydraulic rod 32 and provides power to it. Since the air outlet assembly 2 needs to carry functional components with air outlet capabilities, including a fan 22, fan blades 23, and other related parts, its overall weight may be significant. To ensure stable lifting of the air outlet assembly 2, the hydraulic device 31 and the telescopic hydraulic rod 32 are used in combination to complete the function of the lifting assembly 3. To ensure smooth operation during lifting and minimize external interference, multiple telescopic hydraulic rods 32 can be installed. The hydraulic device 31, which provides power to the telescopic hydraulic rod 32, includes a hydraulic pump, oil tank, and control valve. Under the control of the hydraulic oil by the hydraulic device 31, the movement and extension height of the telescopic hydraulic rod 32 are controlled. Figure 1 As shown, three telescopic hydraulic rods 32 are connected below the air outlet assembly 2, located near the corners of the rectangular top projection of the unit assembly 1. One corner lacks a telescopic hydraulic rod 32 to provide more operating space for the user, as other components are located below this side of the unit assembly 1, making it inconvenient to place the telescopic hydraulic rod 32. Since this is applied to an outdoor air conditioner, in outdoor environments with high temperature, high humidity, and direct sunlight, compared to mechanical structures such as stepper motors with lead screws or motors with racks and pinions, the hydraulic device 31 and telescopic hydraulic rods 32 have stronger tolerance to harsh environmental conditions, longer lifespan, and lower failure rate. In the outdoor air conditioner of this embodiment, the hydraulic system, in conjunction with the control system, can achieve remote operation or automatic lifting and lowering, thereby improving the user experience. Furthermore, the hydraulic device 31 is equipped with a self-diagnostic function to monitor the operating status of the outdoor unit in real time. If a malfunction occurs in the hydraulic system, it promptly alerts the user to perform maintenance to prevent potential dangers.

[0029] In one embodiment, reference is made to Figure 3 , Figure 4 and Figure 7The air outlet assembly 2 includes a grille 21, a fan 22, and fan blades 23. The fan 22 is connected below the grille 21, and the fan blades 23 are connected below the fan 22. The upper end of the telescopic hydraulic rod 32 is connected to the grille 21. In the outdoor unit air conditioner of this embodiment, the function of the air outlet assembly 2 is to achieve upward airflow, thereby completing the air exchange between the inside and outside of the air conditioner. The air outlet assembly 2 includes a grille 21, a fan 22, and fan blades 23. The grille 21, as the upper structure of the air outlet assembly 2, not only serves an aesthetic purpose but also prevents foreign objects from entering the fan 22. It may also have a certain air guiding function to help distribute the airflow evenly and prevent accidents caused by excessively concentrated airflow. The fan 22 is located below the grille 21 and is responsible for driving the airflow. The fan 22 is hung upside down below the grille 21 and is stably connected to the grille 21 by fixing bolts 24. The fan 22 has a waterproof casing, and to prevent dust accumulation on the casing 12, the center of the grille 21 has a protective surface slightly larger than the vertical projection area of ​​the fan 22. This protective surface reduces direct contact between the fan 22 and rainwater, thus reducing dust accumulation, extending the lifespan of the fan 22, and simplifying cleaning for users. The fan 22's shaft faces downwards, and the fan blades 23 are mounted on the shaft; the fan blades 23 are axial flow spiral fan blades. The upper end of the telescopic hydraulic rod 32 is connected to the bottom of the grille 21. During the extension of the telescopic hydraulic rod 32, the grille 21, fan 22, and fan blades 23 are simultaneously lifted, allowing the grille 21 to change its relative position along with the fan 22 and fan blades 23, facilitating maintenance and cleaning. By raising the entire air outlet assembly 2, users can easily access the fan 22 and fan blades 23 for cleaning and maintenance. Maintaining the main moving parts is especially important during long-term use of the air conditioner. Regular cleaning can improve the efficiency of the air conditioner, ensure the dynamic balance of the moving parts, and extend its service life.

[0030] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4The unit assembly 1 has an upward-opening cavity 14. When the telescopic hydraulic rod 32 retracts, the fan 22 and fan blades 23 are located within the cavity 14. When the telescopic hydraulic rod 32 extends, the fan 22 and fan blades 23 are positioned above the unit assembly 1. The upward-opening cavity 14 on the unit assembly 1 allows the fan 22 and fan blades 23 to be fully inserted within it when the telescopic hydraulic rod 32 retracts, protecting the internal components from external environmental influences and reducing the size and unsightly appearance of the equipment. When the telescopic hydraulic rod 32 retracts, the fan 22 and fan blades 23 are located within the cavity 14, meaning that the air conditioner can conceal the fan 22 and fan blades 23 within the unit when cleaning is not required, reducing external exposure and improving overall appearance and safety. When the telescopic hydraulic rod 32 extends, the fan 22 and fan blades 23 are raised above the unit assembly 1, allowing users easier access to key components of the outdoor air conditioner during regular inspections and cleaning, reducing maintenance time and costs, enhancing flexibility, and making cleaning more efficient. In urban high-rise buildings or narrow spaces, this type of outdoor air conditioner, which features upward airflow and is easy to clean, effectively reduces the footprint and is therefore more attractive.

[0031] In one embodiment, reference is made to Figures 3 to 5 The periphery of the grille 21 is provided with at least one rod connecting portion 25, and the upper end of the telescopic hydraulic rod 32 is connected to the rod connecting portion 25. On the periphery of the grille 21, rod connecting portions 25 are provided in pairs according to the number of telescopic hydraulic rods 32. The rod connecting portion 25 provides a stable connection point, allowing the telescopic hydraulic rod 32 to be effectively connected to the grille 21. The presence of the rod connecting portion 25 also increases the distance between the telescopic hydraulic rods 32, making them more stable when extended and raised. It also increases the interference distance between the hydraulic rods and the fan blades 23 of the fan 22, thereby allowing the use of larger radial fan blades 23 to improve the airflow efficiency of the outdoor unit air conditioner. Figure 5As shown, a recessed cavity is provided below the rod connecting part 25, and the top of the piston rod 322 of the telescopic hydraulic rod 32 is located inside the recessed cavity. The end face of the top of the piston rod 322 and the adjacent peripheral side face are in contact with the inner wall surface and the bottom surface of the cavity, so that the piston rod 322 can achieve stable axial and radial force transmission of the piston rod 322 without the use of connecting parts, thereby enhancing the strength of the overall structure and improving the stability of the equipment during operation. The top of the outdoor unit air conditioner is easily affected by harsh environmental factors such as exposure to sunlight, high temperature, electrochemical corrosion, and rainwater erosion. In particular, it has been found during use that when the top of the piston rod 322 is connected to the grid 21 by metal bolts, the piston rod 322 is prone to electrochemical corrosion, resulting in aging and rust, which can lead to leakage and failure of the telescopic hydraulic rod 32 in severe cases. The recessed cavity below the rod connecting part 25 avoids the use of connecting parts and extends the service life of the telescopic hydraulic rod 32. Furthermore, eliminating the use of connectors reduces the number of parts, which helps lower manufacturing and maintenance costs.

[0032] In one embodiment, refer to 3 and Figure 4The unit assembly 1 also includes a base 11 and a housing 12. The housing 12 is located above the base 11, and the grille 21 is located above the housing 12. A cavity 14 is formed by a downward indentation from the top of the housing 12. The lower end of the telescopic hydraulic rod 32 is connected and fixed to the base 11. The unit assembly 1 also includes a top cover 13, which is connected above the housing 12. The top cover 13 has at least one rod guide hole 132 through which the telescopic hydraulic rod 32 passes. When the telescopic hydraulic rod 32 retracts, the top cover 13 abuts against the grille 21. The unit assembly 1 of the outdoor unit air conditioner consists of multiple parts, including the base 11, the housing 12, and the top cover 13. Because the air outlet assembly 2 of the outdoor unit air conditioner in this embodiment is located high in the whole, the fan 22 and the fan blades 23 in the air outlet assembly 2 usually have a large mass, which makes the center of gravity of the outdoor unit air conditioner in this embodiment relatively high. To ensure stable operation of the outdoor unit air conditioner, a base 11 is provided at the bottom of the unit assembly 1, and a casing 12 is mounted on the base 11, serving as the main supporting structure. The horizontal dimension of the base 11 is larger than that of the casing 12, and the bottom outer wall of the casing 12 is enclosed within a raised edge structure on the upper edge of the base 11. A cavity 14 is formed from the upper lower limit of the casing 12. Other functional components of the outdoor unit air conditioner, including a hydraulic device 31, are mounted on the base 11 and are bolted to the cylinder 321 of the hydraulic rod via a mounting flange 324, ensuring stable installation of the telescopic hydraulic rod 32. The casing 12 has a certain height to provide space for airflow within the cavity 14 to achieve the heat dissipation function of the outdoor unit air conditioner. A top cover 13 is connected to the top of the casing 12, which is used to enclose the top structure of the machine. In this embodiment of the invention, the top cover 13 is provided with a rod hole 131 for the piston rod 322 of the telescopic hydraulic rod 32 to pass through. A shock-absorbing sleeve 133 is installed on the inner wall of the through-hole 131. When the telescopic hydraulic rod 32 retracts, a portion of the rod connecting part 25 sinks into the through-hole 131 and abuts against the shock-absorbing sleeve 133, reducing the impact of moving contact between parts. Simultaneously, when the fan 22 drives the fan blade 23, the grid cover 21 will experience radial vibration. The conventional method is to install a shock-absorbing component between the contact portion of the grid cover 21 and the top cover 13. However, because a certain level of sealing must be maintained between the grid cover 21 and the top cover 13, the size of this shock-absorbing seal is very large, resulting in extremely high production costs. Based on this problem, installing a shock-absorbing sleeve 133 in the through-hole 131 can reduce the radial vibration of the grid cover 21 by the abutment between the rod connecting part 25 and the shock-absorbing sleeve 133, thereby reducing the strength requirements of the aforementioned shock-absorbing seal and lowering costs. Furthermore, if the dynamic balance properties of the fan blade 23 are excellent, the shock-absorbing seal may not be needed. Below the through-rod hole 131 of the top cover 13, there is also a guide hole 132. The guide hole 132 fits into the piston rod 322 and its function is to guide the movement of the piston rod 322 and further improve stability.Since outdoor air conditioner units are often installed at high locations, they may be affected by crosswinds during cleaning. When the telescopic hydraulic rod 32 is extended, because the fan 22 and fan blades 23, which have a relatively large mass, are installed under the grille 21, the telescopic hydraulic rod 32 itself does not have the ability to resist lateral loads and torque. If the crosswind is too strong, it will cause damage to the telescopic hydraulic rod 32, preventing it from retracting properly. At this time, the guide hole 132 can provide some lateral support, thereby protecting the telescopic hydraulic rod 32. When the telescopic hydraulic rod 32 retracts, the top cover 13 abuts against the grille 21, and the grille 21 rests on the top cover 13. The contact surface between the grille 21 and the top cover 13 is a circular curved surface. At this time, the grille 21 is supported in the radial direction by the contact surface from all directions. When the fan 22 drives the fan blades 23 to rotate, it will be more stable, with less vibration and noise, improving the user experience.

[0033] In one embodiment, reference is made to Figures 6 to 9The hydraulic device 31 includes a flow divider valve 311 and at least one hydraulic line 312. The hydraulic line 312 is connected to the flow divider valve 311, and at least one hydraulic line 312 is paired with a telescopic hydraulic rod 32. The hydraulic device 31 also has a first valve 313 and a second valve 314, which are connected to the flow divider valve 311. The first valve 313 is used to connect to a high-pressure liquid line, and the second valve 314 is used to connect to a low-pressure liquid line. The hydraulic device 31 consists of the flow divider valve 311 and the hydraulic line 312. The flow divider valve 311, as the core component, distributes hydraulic power to multiple lines as needed, controlling the flow direction and pressure of the liquid in the hydraulic system. At least one hydraulic line 312 is paired with a telescopic hydraulic rod 32, that is, hydraulic power is transmitted to each telescopic hydraulic rod 32 through the hydraulic line 312, thereby controlling the movement of the lifting assembly 3. The function of the flow divider valve 311 is to distribute hydraulic power as needed. The diverter valve 311 is directly connected to the telescopic hydraulic rod 32 via a hydraulic line 312, ensuring controllability and flexibility of the fluid flow. Each telescopic hydraulic rod 32 has a dedicated hydraulic line 312 for fluid supply, which connects to the exchange port 323 on the cylinder 321 of the telescopic hydraulic rod 32 for independent control. This allows different telescopic hydraulic rods 32 to extend and retract individually as needed, adjusting the height of the air outlet assembly 2 according to changes in fluid flow and pressure, ensuring precise adjustment and stability of the air outlet assembly 2. The first valve 313 and the second valve 314 are respectively connected to the diverter valve 311 to control the fluid flow in the hydraulic system. The first valve 313 is used to connect to the high-pressure fluid line, which supplies high-pressure fluid to the hydraulic device 31, driving the telescopic hydraulic rod 32 to achieve a wide range of lifting and separation operations. The second valve 314 is used to connect to the low-pressure fluid line, controlling the inflow of low-pressure fluid to maintain system stability or slowly adjust the state of the telescopic hydraulic rod 32 when strong actuation is not required. The first valve 313 and the second valve 314 are solenoid valves or pneumatic valves to ensure rapid response. High-efficiency hydraulic oil is used in the hydraulic circuit to ensure a smooth lifting process and avoid vibration.

[0034] To more clearly illustrate the working principle of the lifting component 3, the following is an example of the cleaning process of an outdoor unit air conditioner according to an embodiment of the present invention.

[0035] When the outdoor unit air conditioner is in normal operation, the first valve 313 and the second valve 314 of the hydraulic device 31 are closed, the hydraulic rod is not working, and the grille 21 and the top cover 13 are in a closed, engaged state. When the outdoor unit air conditioner starts the cleaning mode, the first valve 313 is opened and the second valve 314 is closed, and the hydraulic rod begins to work. The air outlet assembly 2 is lifted to a set height, the grille 21 and the top cover 13 separate, and the fan 22 and fan blades 23 rise above the top cover 13 for cleaning. After cleaning is completed, the second valve 314 is opened, the hydraulic rod is compressed under gravity, and the air outlet assembly 2 descends and resets to the closed state between the grille 21 and the top cover 13. Finally, the second valve 314 closes, and the outdoor unit air conditioner returns to normal operation.

[0036] In one embodiment, the outdoor unit air conditioner also includes an intelligent control system, which includes various photoelectric sensors for real-time monitoring of the outdoor unit's operating status and pollution level. It automatically determines when cleaning is needed and alerts the user via remote communication or indicator lights on the unit. The system also automatically adjusts its height based on user input. This intelligent control system allows users to remotely control and monitor the unit via a mobile app or smart home system. This eliminates the need for an external user control panel, which is often susceptible to damage from harsh environmental conditions such as direct sunlight and rain. Eliminating the user control panel reduces manufacturing costs and extends the lifespan of the outdoor unit air conditioner. Only a remote communication module needs to be installed inside the casing 12.

[0037] Furthermore, the outdoor unit air conditioner also includes an automatic cleaning device, such as a high-pressure water gun or fan cleaning system, which regularly and automatically cleans the internal components, further reducing the frequency of manual cleaning. The automatic cleaning device is linked to the intelligent control system, which automatically determines when cleaning is needed without human intervention, and then performs a certain degree of cleaning through the automatic cleaning device, thereby reducing the frequency of manual cleaning and reducing maintenance pressure.

[0038] Furthermore, the outdoor unit air conditioner also includes a self-diagnostic system that monitors the operating status of the outdoor unit in real time. If faults such as hydraulic system abnormalities or fan blade imbalance occur, it can promptly remind the user to perform maintenance.

[0039] In one embodiment, in areas experiencing extreme weather conditions such as typhoons and sandstorms, the outdoor unit air conditioner of this invention employs a modular design for its components to facilitate maintenance and repair. This modular design allows for easy replacement and upgrades of individual components, enhancing the product's maintainability and adaptability. The connections between non-metallic components are secured using snap-fit ​​and interference fits, reducing the number of metal connectors and adding user-identifiable indicators, enabling users to easily perform cleaning and maintenance even without specialized knowledge. All components directly exposed to the outside are made of lightweight, high-strength, environmentally friendly materials, improving weather resistance and reducing environmental impact.

[0040] Embodiments of the present invention also provide an outdoor unit air conditioner control method, referring to... Figure 10 This includes the following specific steps.

[0041] S410, Obtain the cleanliness status of the interior of the outdoor unit air conditioner;

[0042] S420: When the cleanliness level reaches the cleanliness threshold, a cleaning requirement alert is sent to the user.

[0043] S430: Receives the user's input cleaning mode start command and controls the lifting component 3 to lift the air outlet component 2 so that the air outlet component 2 is separated from the body component 1.

[0044] S440: Receive the user's input command to end the cleaning mode, and control the lifting component 3 to lower the air outlet component 2 so that the air outlet component 2 engages and resets with the body component 1.

[0045] The intelligent control system also includes a cleanliness monitoring system, which monitors the cleanliness of the unit component 1 and the air outlet component 2 in real time. Cleanliness is determined by detecting indicators such as internal dust accumulation, pollutants, and airflow. The cleanliness monitoring system can use air quality sensors, dust sensors, or infrared sensors to monitor the amount of dust inside the air conditioner. The sensor data acquisition module needs to connect to other subsystems of the air conditioner's intelligent control system to transmit cleanliness data. When the cleanliness level reaches a set threshold, the system automatically issues a cleaning alert. This function is accomplished by the machine's built-in LED indicator and by sending commands to the user's mobile app via a remote communication module. It can also be integrated with the user's smart home system for convenient user notification. The remote communication module is located in the user interface system, allowing users to input commands via remote control, control panel, or smartphone application. The intelligent control system includes a mode switching module that handles the start and end commands for the cleaning mode. When the cleaning mode is activated, the system controls the lifting component 3 via the received command, separating the air outlet component 2 from the unit component 1. When the cleaning mode ends, the system controls the lifting component 3 via commands, causing the air outlet component 2 to reconnect and reset with the body component 1. During this process, the hydraulic device 31 and the telescopic hydraulic rod 32 are linked with the intelligent control system of the outdoor unit air conditioner through the first valve 313 and the second valve 314. The first valve 313 and the second valve 314 are electronically controlled valves, which receive commands from the control system to control the opening and closing of the hydraulic fluid pipeline, its flow direction, or its pressure, thereby adjusting the extension and retraction state of the telescopic hydraulic rod 32.

[0046] The system acquires sensor data periodically or in real time to obtain the cleanliness status of the air conditioner's interior and compares it with preset cleanliness standards to determine whether the cleanliness threshold has been reached.

[0047] To determine if the cleanliness level has reached a threshold, the control system continuously monitors and analyzes cleanliness data in real time. If the cleanliness data reaches or exceeds the preset threshold, the system will issue a cleaning request alert. After issuing the alert, the control system checks if the cleanliness level meets the threshold. If so, the system will issue a cleaning reminder via an alert system, such as a warning light or display screen. If the outdoor unit air conditioner is connected to a smart home system or mobile app, the system can also push cleaning reminder notifications through these devices.

[0048] Upon receiving a user-input cleaning mode activation command, the control system controls the lifting assembly 3 to raise the air outlet assembly 2, separating it from the body assembly 1. When the user activates the cleaning mode, the control system instructs the hydraulic device 31 to extend the telescopic hydraulic rod 32, raising the air outlet assembly 2 and creating a space for easy cleaning. The intelligent control system sends a command to the valve to deliver high-pressure liquid to the telescopic hydraulic rod 32. Under the action of the hydraulic system, the telescopic hydraulic rod 32 extends, causing the air outlet assembly 2 to rise until it is completely separated from the body assembly 1. At this point, the user or maintenance personnel can easily clean the air outlet assembly 2 and the components within the cavity 14.

[0049] Upon receiving a user-inputted end-of-cleaning-mode command, the intelligent control system controls the lifting component 3 to lower the air outlet component 2, resetting it to engage with the body component 1. When the end-of-cleaning-mode command is received, the intelligent control system sends a command to the valve, causing the telescopic hydraulic rod 32 to retract, lowering the air outlet component 2 and restoring it to its engaged position with the body component 1. The intelligent control system then controls the hydraulic valve via commands, switching the hydraulic system to a low-pressure mode or shutting off the fluid flow. Under the action of the low-pressure fluid, the telescopic hydraulic rod 32 begins to retract, the air outlet component 2 gradually descends, and finally engages with the body component 1, returning to normal operating condition.
