[0002] As people's requirements for quality of life and comfort continue to improve, air conditioners, as important household appliances, are gaining more and more attention from consumers. However, during the use of traditional air conditioner outdoor units, due to their long-term exposure to the outdoor environment, dust, dirt and other pollutants are easily accumulated, resulting in reduced heat exchange efficiency and even affecting the normal operation of the air conditioner. In addition, the cleaning of the outdoor unit usually requires professional maintenance personnel, which not only increases the maintenance cost of users, but also brings inconvenience.

[0003] In the prior art, the design of most air conditioner outdoor units does not take into account convenient cleaning methods. Users often need to disassemble multiple parts when cleaning the outdoor unit, which is a cumbersome and time-consuming process. Moreover, some outdoor unit designs lack reasonable protective measures, resulting in the inability to fully restore to the optimal working state after cleaning. This is especially true for air outlet components such as fan blades and fans in the air conditioner outdoor unit. If the position cannot be restored correctly, it will cause dynamic imbalance and produce severe vibrations, affecting the life of the equipment and user experience. Therefore, how to facilitate users to clean the air outlet components of the outdoor unit to improve the efficiency of the air conditioner and extend its service life has become an urgent problem to be solved.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0026] In order to solve the problem of difficulty in cleaning the air outlet assembly 2 of the outdoor air conditioner in the prior art, the present invention proposes an outdoor air conditioner and a control method. Figures 1 to 9The outdoor air conditioner of the embodiment of the present invention includes: a body assembly 1; an air outlet assembly 2, which is arranged above the body assembly 1, and the air outlet assembly 2 is used to exchange gas inside and outside the body assembly 1; a lifting assembly 3, which connects the body assembly 1 and the air outlet assembly 2, and the lifting assembly 3 drives the air outlet assembly 2 to be lifted and separated or lowered and joined relative to the body assembly 1. The so-called body assembly 1 is the main structural unit of the outdoor air conditioner, and the body assembly 1 usually includes key components such as a heat exchanger, a compressor, and a heat pipe. The so-called air outlet assembly 2 provides power to drive the airflow through the fan blades 23, which is arranged above the body assembly 1 and is responsible for discharging the treated air or introducing the outside air. The lifting assembly 3 connects the body assembly 1 and the air outlet assembly 2, and realizes the lifting and lowering of the air outlet assembly 2 through hydraulic or mechanical devices, thereby realizing the separation and joining of the air outlet assembly 2 relative to the body, which provides convenience for the cleaning and maintenance of the outdoor unit. The outdoor unit air conditioner of the embodiment of the present invention lifts the air outlet component 2 through the lifting component 3, so that sufficient manual operation space is obtained between the body component 1 and the fan 22 component after being lifted and separated by the lifting component 3, so that the user can easily clean and maintain, reducing the risk of reduced heat exchange efficiency due to dust accumulation in the outdoor unit. The overall structure has a simple operation mode. After being lifted and separated by the lifting component 3, the user can perform daily maintenance without professional knowledge, which improves the user experience. At the same time, after sufficient cleaning, the performance, convenience and durability of the air conditioner can also be improved. And the adaptability of the outdoor unit air conditioner in specific environments is enhanced, such as in different installation locations or climatic conditions, making the outdoor unit air conditioner more versatile.

[0027] Compared with the prior art, in an embodiment of the present invention, by connecting the lifting component 3 to the air outlet component 2 arranged above the body component 1, the lifting separation and lowering connection between the air outlet component 2 and the body component 1 are achieved under the action of the lifting component 3, so that the air outlet component 2 and the inside of the body component 1 on which the air outlet component 2 is installed can have sufficient cleaning operation space, thereby making it easier to clean.

[0028] In one embodiment, referring 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 respectively connected to the body assembly 1 and the air outlet assembly 2. The hydraulic device 31 is connected to the telescopic hydraulic rod 32, wherein the hydraulic device 31 is used to provide power for the telescopic hydraulic rod 32. Since the air outlet assembly 2 needs to carry functional devices with air outlet functions, including a fan blower 22, fan blades 23 and other related components, the overall weight of the air outlet assembly 2 may be relatively large. In order to stably lift the air outlet assembly 2, the hydraulic device 31 and the telescopic hydraulic rod 32 are selected to combine and complete the function of the lifting assembly 3. In order to ensure smooth operation during the lifting process and not easily affected by external interference, a plurality of telescopic hydraulic rods 32 may be set. The hydraulic device 31 is responsible for providing power for the telescopic hydraulic rod 32, and includes a hydraulic pump, an oil tank and a control valve. Under the control of the hydraulic oil by the hydraulic device 31, the movement and telescopic height control of the telescopic hydraulic rod 32 are realized. Figure 1 As shown, three telescopic hydraulic rods 32 are connected below the air outlet assembly 2, which are arranged at the position close to the rectangular corner of the body assembly 1 close to the top projection of the rectangle. The telescopic hydraulic rod 32 is not arranged at one corner to free up more operating space for the user. At the same time, the body assembly 1 is also provided with other components below this side, which is not convenient for arranging the telescopic hydraulic rod 32. Because it is applied to outdoor air conditioners, in the high temperature, high humidity and exposure environment that may exist outdoors, compared with the lifting method using a mechanical structure, such as a stepper motor plus a screw rod or a motor plus a gear rack, the hydraulic device 31 and the telescopic hydraulic rod 32 have a stronger tolerance to harsh environmental conditions, a longer life and a lower failure rate. In the outdoor air conditioner of the embodiment of the present invention, the hydraulic system cooperates with the control system to realize remote operation or automatic lifting and lowering, thereby improving the user experience. Furthermore, a self-diagnosis function is also provided in the hydraulic device 31 to monitor the operating status of the outdoor unit in real time. If a fault occurs and the hydraulic system is abnormal, the user is reminded to perform maintenance in time to prevent danger.

[0029] In one embodiment, referring to Figure 3 , Figure 4 and Figure 7, the air outlet assembly 2 includes a grille cover 21, a fan 22 and a fan blade 23, the fan 22 is connected to the bottom of the grille cover 21, the fan blade 23 is connected to the bottom of the fan 22, and the upper end of the telescopic hydraulic rod 32 is connected to the grille cover 21. In the outdoor unit air conditioner of the embodiment of the present invention, the function of the air outlet assembly 2 is to realize the upward air outlet, thereby completing the ventilation inside and outside the air conditioner body. The air outlet assembly 2 includes a grille cover 21, a fan 22 and a fan blade 23. The grille cover 21, as the upper structure of the air outlet assembly 2, not only plays a role in aesthetics, but also prevents foreign matter from entering the inside of the fan 22. At the same time, it may have a certain wind guiding function, helping the airflow to be evenly distributed, and preventing some unexpected situations caused by excessive concentration of airflow. The fan 22 is located below the grille cover 21 and is responsible for promoting air flow. The fan 22 is hung upside down below the grille cover 21, and is stably connected to the grille cover 21 through a fixing bolt 24. The fan 22 has a waterproof housing, and in order to prevent dust from accumulating on the fan 22 housing 12, there is a protective surface in the center of the grille cover 21 that is slightly larger than the vertical projection area of ​​the fan 22 body. The protective surface can reduce the direct contact between the fan 22 and rain and reduce dust to a certain extent, which not only increases the life of the fan 22, but also reduces the difficulty of cleaning for users. The rotating shaft of the fan 22 faces downward, and the fan blades 23 are installed on the rotating shaft of the fan 22. The fan blades 23 are axial flow spiral fan blades 23. The upper end of the telescopic hydraulic rod 32 is connected to the bottom of the grille cover 21. When the telescopic hydraulic rod 32 is extended, the grille cover 21, the fan 22 and the fan blades 23 are lifted up at the same time, so that the grille cover 21 can change the relative position with the fan 22 and the fan blades 23 to facilitate maintenance and cleaning. By lifting the entire air outlet assembly 2, the user can easily access the fan 22 and the fan blades 23 for cleaning and maintenance. It is particularly important to maintain the main moving parts during the 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 the service life.

[0030] In one embodiment, referring to Figure 1 , Figure 3 and Figure 4, a cavity 14 opening upward is provided in the body assembly 1. When the telescopic hydraulic rod 32 is retracted, the fan 22 and the fan blade 23 are located in the cavity 14. When the telescopic hydraulic rod 32 is extended, the fan 22 and the fan blade 23 are located above the body assembly 1. The cavity 14 opening upward on the body assembly 1 allows the fan 22 and the fan blade 23 to fully enter the cavity when the telescopic hydraulic rod 32 is retracted, protecting the internal components from the external environment, while also reducing the volume and abrupt appearance of the equipment. When the telescopic hydraulic rod 32 is retracted, the fan 22 and the fan blade 23 are located in the cavity 14, which means that the air conditioner can hide the fan 22 and the fan blade 23 in the body when cleaning is not required, reducing external exposure and improving the overall appearance and safety. When the telescopic hydraulic rod 32 is extended, the fan 22 and the fan blade 23 are lifted above the body assembly 1, and the user can more conveniently access the key components of the outdoor air conditioner when performing regular inspections and cleaning, reducing maintenance time and costs, enhancing flexibility, and making cleaning work more efficient. In urban high-rise buildings or narrow spaces, this outdoor air conditioner with upward air flow and easy cleaning effectively reduces the footprint and is more attractive.

[0031] In one embodiment, referring to Figures 3 to 5 , at least one rod connection part 25 is provided on the circumferential side of the grille cover 21, and the upper end of the telescopic hydraulic rod 32 is connected to the rod connection part 25. Rod connection parts 25 are provided in pairs on the circumferential side of the grille cover 21 according to the number of telescopic hydraulic rods 32. The rod connection parts 25 provide a stable connection point so that the telescopic hydraulic rod 32 can be effectively connected to the grille cover 21. The existence of the rod connection parts 25 also increases the distance between the telescopic hydraulic rods 32, making the telescopic hydraulic rods 32 more stable when they are extended and lifted, and also increases the interference distance between the hydraulic rods and the fan blades 23 of the fan 22, so that the fan blades 23 with larger radial dimensions can be used to improve the air outlet efficiency of the outdoor air conditioner. Figure 5As shown, a concave cavity is provided below the rod body connection part 25, and the top of the piston rod 322 of the telescopic hydraulic rod 32 is located in the concave cavity. The end face of the top of the piston rod 322 and the adjacent peripheral side face are fitted with the inner wall surface of the concave cavity and the cavity bottom surface of the concave cavity, so that the grid cover 21 and the piston rod 322 of the telescopic hydraulic rod 32 can also achieve axial and radial stable force transmission of the rod body of the piston rod 322 by fitting without using a connecting piece, 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 the sun, high temperature, electrochemical, and rain erosion. In particular, it is found during use that when the top of the piston rod 322 is connected to the grid cover 21 by a metal bolt, the piston rod 322 is easily aging and rusting due to electrochemical corrosion, and in severe cases, the telescopic hydraulic rod 32 leaks and fails. Through the concave cavity below the rod body connection part 25, the use of connecting pieces is avoided, and the service life of the telescopic hydraulic rod 32 is extended. In addition, not using connectors reduces the number of parts, helping to reduce manufacturing and maintenance costs.

[0032] In one embodiment, referring to 3 and Figure 4The body assembly 1 is also provided with a base 11 and a housing 12. The housing 12 is provided above the base 11. The grille cover 21 is provided above the housing 12. The cavity 14 is formed by being recessed downward 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 body assembly 1 is also provided with a top cover 13. The top cover 13 is connected above the housing 12. The top cover 13 is provided with at least one rod guide hole 132. The telescopic hydraulic rod 32 passes through the rod guide hole 132. When the telescopic hydraulic rod 32 is retracted, the top cover 13 abuts against the grille cover 21. The body assembly 1 of the outdoor unit air conditioner is composed of multiple parts, including a base 11, a housing 12 and a top cover 13. Since the air outlet assembly 2 of the outdoor unit air conditioner in the embodiment of the present invention is located at the upper position 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 the embodiment of the present invention higher. In order to make the outdoor air conditioner stable, a base 11 is provided at the bottom of the body assembly 1, and a housing 12 is provided on the base 11, and the housing 12 serves as the main supporting structure. The horizontal dimension of the base 11 is larger than that of the housing 12, and the bottom outer wall of the housing 12 is wrapped in the edge protection structure that is higher than the upper edge of the base 11. The cavity 14 is formed from the upper lower limit of the housing 12, and other functional components of the outdoor air conditioner including the hydraulic device 31 are installed on the base 11, and are bolted to the cylinder 321 of the hydraulic rod through the mounting flange 324, so that the telescopic hydraulic rod 32 is stably installed. The housing 12 has a certain height, which provides space for the air flow in the cavity 14 to realize the heat dissipation function of the outdoor air conditioner. The top of the housing 12 is connected to the top cover 13, and the top cover 13 is used to close the top structure of the machine. In the embodiment of the present invention, the top cover 13 is provided with a rod hole 131 for passing the piston rod 322 of the telescopic hydraulic rod 32. A shock-absorbing sleeve 133 is installed on the inner wall of the rod hole 131. When the telescopic hydraulic rod 32 is retracted, a part of the rod body connection part 25 will sink into the rod hole 131 and abut against the shock-absorbing sleeve 133, reducing the impact of the moving contact between the parts. At the same time, when the fan 22 drives the fan blade 23 to operate, the grille cover 21 will produce radial vibration. The conventional method is to set a shock-absorbing component between the contact part of the grille cover 21 and the top cover 13. However, since a certain sealing performance must be ensured between the grille cover 21 and the top cover 13, the size of the shock-absorbing seal is very large and the production cost is extremely high. Based on this problem, the shock-absorbing sleeve 133 is set in the rod hole 131 to reduce the radial vibration of the grille cover 21 by means of the abutment between the rod body connection part 25 and the shock-absorbing sleeve 133, thereby reducing the strength requirements of the above-mentioned shock-absorbing seal and reducing the cost. Even if the dynamic balance property of the fan blade 23 is excellent, the shock-absorbing seal is not used. A guide hole 132 is provided coaxially below the rod hole 131 of the top cover 13 . The guide hole 132 fits the piston rod 322 and serves to guide the movement of the piston rod 322 and further improve stability.Since outdoor air conditioners are often installed at high places, they may be affected by high-altitude crosswinds during the cleaning process. When the telescopic hydraulic rod 32 is in the extended state, since the fan 22 and the fan blades 23 with large mass are installed under the grille cover 21, the telescopic hydraulic rod 32 itself does not have the ability to resist lateral loads and torque. If the crosswind is too strong, the telescopic hydraulic rod 32 will be damaged, resulting in the inability of the telescopic hydraulic rod 32 to retract normally. At this time, the guide hole 132 can provide certain lateral support to protect the telescopic hydraulic rod 32. When the telescopic hydraulic rod 32 retracts, the top cover 13 abuts against the grille cover 21, and the grille cover 21 is mounted on the top cover 13. The contact surface between the grille cover 21 and the top cover 13 is a circular curved surface. At this time, the grille cover 21 is supported by the contact surfaces from all directions around it in the radial direction. When the fan 22 drives the fan blades 23 to rotate, it will be more stable, and the vibration and noise generated will be less, which improves the user experience.

[0033] In one embodiment, referring to Figures 6 to 9The hydraulic device 31 includes a liquid diverter valve 311 and at least one hydraulic pipeline 312, the hydraulic pipeline 312 is connected to the diverter valve 311, and at least one hydraulic pipeline 312 is connected to the telescopic hydraulic rod 32 in pairs; the hydraulic device 31 is also provided with a first valve 313 and a second valve 314, the first valve 313 and the second valve 314 are connected to the diverter valve 311, the first valve 313 is used to connect the high-pressure liquid pipeline, and the second valve 314 is used to connect the low-pressure liquid pipeline. The hydraulic device 31 is composed of a liquid diverter valve 311 and a hydraulic pipeline 312. The liquid diverter valve 311 is a core component, and its function is to distribute liquid power to multiple pipelines as required, and control the flow direction and pressure of the liquid in the hydraulic system. At least one hydraulic pipeline 312 is connected to the telescopic hydraulic rod 32 in pairs, that is, the hydraulic power is transmitted to each telescopic hydraulic rod 32 through the hydraulic pipeline 312, so as to control the movement of the lifting assembly 3. The function of the liquid diverter valve 311 is to distribute the hydraulic power as required. The diverter valve 311 is directly connected to the telescopic hydraulic rod 32 through the hydraulic pipeline 312 to ensure the controllability and flexibility of the liquid flow. Each telescopic hydraulic rod 32 has a dedicated hydraulic pipeline 312 to supply liquid, and the hydraulic pipeline 312 is connected to the exchange port 323 on the cylinder 321 of the telescopic hydraulic rod 32 to achieve independent control. This allows different telescopic hydraulic rods 32 to be individually extended and retracted according to demand, and the height of the air outlet assembly 2 is adjusted according to the changes in liquid flow and pressure, ensuring the 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 flow of liquid in the hydraulic system. The first valve 313 is used to connect the high-pressure liquid pipeline, which provides high-pressure liquid to the hydraulic device 31 and drives the telescopic hydraulic rod 32 to achieve a large range of lifting and separation operations. The second valve 314 is used to connect the low-pressure liquid pipeline, which controls the inflow of low-pressure liquid so as to maintain the stability of the system or slowly adjust the state of the telescopic hydraulic rod 32 when no strong push is required. The first valve 313 and the second valve 314 use solenoid valves or pneumatic valves to ensure rapid response. High-efficiency hydraulic oil is used in the hydraulic oil circuit to ensure a smooth lifting process and avoid vibration.

[0034] In order to more clearly illustrate the working principle of the lifting assembly 3, an example of a cleaning process of an outdoor air conditioner according to an embodiment of the present invention is given below.

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

[0036] In one embodiment, the outdoor air conditioner also includes an intelligent control system, which includes a variety of photoelectric sensors for real-time monitoring of the working status and pollution level of the outdoor unit, automatically determining when cleaning is required, and notifying the user through remote communication or the indicator light on the fuselage, and automatically performing lifting and lowering operations according to user operations. The intelligent control system allows users to remotely control and monitor through a mobile phone APP or a smart home system, so there is no need to arrange a user control interaction panel on the outside of the outdoor air conditioner, because the user control interaction panel is usually susceptible to harsh environmental conditions such as sunlight exposure and rain erosion. The absence of a user control interaction panel can reduce the manufacturing cost of the outdoor air conditioner and increase the service life of the outdoor air conditioner. It is only necessary to arrange a remote communication module in the housing 12.

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

[0038] Furthermore, the outdoor unit air conditioner also includes a self-diagnosis system to monitor the operating status of the outdoor unit in real time. If there are faults such as hydraulic system abnormalities, imbalance of the fan blades 23, etc., the user can be reminded to perform maintenance in time.

[0039] In one embodiment, in some areas with extremely bad weather such as typhoons and sandstorms, in order to facilitate the repair and maintenance of the outdoor air conditioner, the components of the outdoor air conditioner of the present invention also adopt a modular design to facilitate the replacement and upgrading of each component, thereby improving the maintainability and adaptability of the product. The connection and fixation between each non-metallic component is completed by snap-fit ​​and interference fit, reducing metal connectors and increasing user-identifiable instructions, so that users can easily clean and maintain even without professional knowledge. All components directly exposed to the outermost part are made of lightweight and high-strength environmentally friendly materials to improve weather resistance and reduce the impact on the environment.

[0040] The embodiment of the present invention also provides a method for controlling an outdoor air conditioner. Fig.10 , including the following specific steps.

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

[0042] S420, when the cleanliness condition reaches the cleanliness threshold, a cleaning requirement warning is issued to the user;

[0043] S430, receiving a cleaning mode start instruction input by a user, and controlling 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, receiving the cleaning mode end instruction input by the user, and controlling the lifting component 3 to lower the air outlet component 2 so that the air outlet component 2 is engaged with the body component 1 and reset.

[0045] The intelligent control system also includes a cleanliness monitoring system, which is used to detect the cleanliness of the body component 1 and the air outlet component 2 in real time, and judge the cleanliness by detecting indicators such as internal dust accumulation, pollutants or air circulation status. The cleanliness monitoring system can use equipment such as air quality sensors, dust sensors or infrared sensors to monitor the amount of dust accumulated inside the air conditioner. The sensor data acquisition module needs to be connected to other subsystems of the intelligent control system of the air conditioner to transmit the cleanliness data to other subsystems of the intelligent control system. When the cleanliness condition reaches the set cleanliness threshold, the system needs to automatically issue a cleaning demand warning. This function is completed by the LED indicator light of the machine itself and sending instructions to the user's mobile phone APP through the remote communication module. It can also be linked with the user's smart home system to facilitate the user to receive warnings. The remote communication module is set in the user interface system, and the user interface system allows the user to input instructions through a remote control, a control panel or a smart phone application. The intelligent control system includes a mode switching module to process the start and end instructions of the cleaning mode. When the cleaning mode is started, the system controls the lifting component 3 through the received instructions to separate the air outlet component 2 from the body component 1. When the cleaning mode ends, the system controls the lifting assembly 3 through instructions to make the air outlet assembly 2 engage and reset with the body assembly 1. In this process, the hydraulic device 31 and the telescopic hydraulic rod 32 complete the linkage 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 instructions from the control system to control the pipeline on-off, flow direction or pressure of the hydraulic fluid, thereby adjusting the telescopic state of the telescopic hydraulic rod 32.

[0046] The cleanliness status inside the outdoor unit air conditioner is obtained. The control system obtains sensor data regularly or in real time and compares it with the preset cleanliness standard to determine whether the cleanliness threshold is reached.

[0047] To determine whether the cleanliness reaches the cleanliness threshold, the control system continuously monitors the cleanliness data and performs real-time analysis. If the cleanliness data reaches or exceeds the preset threshold, the system will issue a cleaning requirement alert. After issuing a cleaning requirement alert, the control system checks whether the cleanliness reaches the threshold. If the conditions are met, the system will issue a cleaning reminder through the warning system, such as warning lights and display screens. If the outdoor air conditioner is connected to a smart home system or mobile phone APP, the system can also push cleaning reminder notifications through these devices.

[0048] After receiving the cleaning mode start command input by the user, the lifting component 3 is controlled to lift the air outlet component 2 to separate the air outlet component 2 from the body component 1. When the user starts the cleaning mode, the control system will instruct the hydraulic device 31 to start, extend the telescopic hydraulic rod 32, lift the air outlet component 2, separate it from the body component 1, and form a space that is easy to clean. 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, driving the air outlet component 2 to rise until the air outlet component 2 is completely separated from the body component 1. At this time, the user or maintenance personnel can easily clean the air outlet component 2 and the components in the area inside the cavity 14.

[0049] Receive the end command of the cleaning mode input by the user, control the lifting component 3 to lower the air outlet component 2, so that the air outlet component 2 is engaged and reset with the body component 1. When receiving the end command of the cleaning mode, the intelligent control system will send a command to the valve to retract the telescopic hydraulic rod 32, drive the air outlet component 2 to descend, and restore the air outlet component 2 to the position engaged with the body component 1. The intelligent control system controls the hydraulic valve through the command to switch the hydraulic system to the low-pressure mode or shut down the liquid flow. The telescopic hydraulic rod 32 begins to retract under the action of the low-pressure liquid, and the air outlet component 2 gradually descends and finally engages with the body component 1, and finally returns to a normal working state.
