Description

Technical Field

[0002] Air conditioning systems play a vital role in modern life and work, not only regulating indoor temperatures to adapt to seasonal changes but also improving indoor air quality by introducing fresh air. However, as people's demands for health and comfort continue to rise, traditional air conditioning systems are struggling to cope with low indoor oxygen levels and poor air quality. Existing solutions primarily include fresh air ventilation devices and oxygen generators. While each can improve the indoor environment to a certain extent, they present a series of problems in practical application.

[0003] Fresh air ventilation systems primarily refresh indoor air quality by introducing outdoor air. However, these systems often focus solely on air circulation and fail to provide an effective solution for reduced indoor oxygen levels. In enclosed environments, especially after prolonged operation, air conditioning systems can cause a decrease in indoor oxygen levels, impacting mental well-being and work efficiency.

[0050] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] As mentioned in the background technology, in order to improve the indoor air quality, existing air conditioners are equipped with fresh air ventilation modules or oxygen production modules inside the body. Although both can improve the indoor environment to a certain extent, there are the following problems: the fresh air ventilation device can only introduce outdoor fresh air into the room. When the room is relatively closed, the indoor oxygen content will decrease; and for air conditioners with oxygen production function, since the oxygen production module is installed and operated independently from the other functions of the air conditioner, a series of pipelines and filtering structures will be added, which greatly increases the complexity of the overall structure of the air conditioner. Therefore, in response to the above technical problems, the air conditioner provided in the present application has an indoor body 100 including a fresh air component 300, which has a fresh air channel 301 therein, and an outdoor body 200 including an oxygen production component 400 for providing oxygen to the indoor room. A first pipe fitting 510 and a second pipe fitting 520 are provided. One end of the first pipe fitting 510 is used to communicate with the outdoor environment, and the other end of the first pipe fitting 510 is connected to the fresh air channel 301 to introduce outdoor fresh air into the fresh air channel 301; the two ends of the second pipe fitting 520 are respectively connected to the fresh air channel 301 and the oxygen production component 400, so that part of the outdoor fresh air in the fresh air channel 301 is discharged into the indoor room, and the other part is transported to the oxygen production component 400 through the second pipe fitting 520 for oxygen production, wherein at least a portion of the first pipe fitting 510 is sleeved on the second pipe fitting 520. This configuration combines the air conditioner's fresh air function with its oxygen production function, utilizing outdoor fresh air to provide an air source for the oxygen production assembly 400. This eliminates the need for a separate outdoor piping structure for air intake and oxygen production. This design significantly reduces the number of external piping, simplifies the air conditioner's installation process, and saves installation space. The air conditioner of this application can simultaneously meet the needs of fresh air ventilation and oxygen replenishment, effectively improving indoor air quality. The introduction of fresh air ensures the circulation and freshness of indoor air, while the oxygen production function ensures sufficient indoor oxygen content. Together, these functions create a healthier indoor environment.

[0052] Please refer to Figures 1 to 10 The present application provides an air conditioner, including an indoor body 100 and an outdoor body 200. The indoor body 100 includes a fresh air component 300, and the fresh air component 300 has a fresh air channel 301, which is used to communicate with the indoor environment; the outdoor body 200 includes an oxygen production component 400 for providing oxygen to the room; the air conditioner also includes a pipe component 500, and the pipe component 500 includes a first pipe 510 and a second pipe 520. One end of the first pipe 510 is used to communicate with the outdoor environment, and the other end of the first pipe 510 is connected to the fresh air channel 301 to introduce outdoor fresh air into the fresh air channel 301; the two ends of the second pipe 520 are respectively connected to the fresh air channel 301 and the oxygen production component 400, so that part of the outdoor fresh air in the fresh air channel 301 is discharged into the room, and the other part is transported to the oxygen production component 400 through the second pipe 520 for oxygen production.

[0053] The air conditioner provided by the present application includes an indoor body 100 and an outdoor body 200. The indoor body 100 includes a fresh air component 300, and the fresh air component 300 has a fresh air channel 301, which is used to communicate with the indoor environment; the outdoor body 200 includes an oxygen production component 400, which is used to provide oxygen to the room; the air conditioner also includes a pipe component 500, and the pipe component 500 includes a first pipe 510 and a second pipe 520. One end of the first pipe 510 is used to communicate with the outdoor environment, and the other end of the first pipe 510 is connected to the fresh air channel 301 to introduce outdoor fresh air into the fresh air channel 301; the two ends of the second pipe 520 are respectively connected to the fresh air channel 301 and the oxygen production component 400, so that part of the outdoor fresh air in the fresh air channel 301 is discharged into the room, and the other part is transported to the oxygen production component 400 through the second pipe 520 for oxygen production.

[0054] By using the first pipe fitting 510 and the second pipe fitting 520, the pipelines for introducing fresh air and oxygen-generating gas are cleverly integrated together, thereby avoiding the problem of traditional oxygen-generating air conditioners requiring additional oxygen-generating air intake pipelines, reducing the complexity of wall drilling and pipeline wiring, simplifying the installation process, and reducing installation costs.

[0055] The second pipe 520 directly obtains the preliminarily filtered outdoor fresh air from the fresh air channel 301, shortening the gas transmission distance, reducing the resistance and energy loss of the air flow during the transmission process, and thus improving the working efficiency of the oxygen production component 400.

[0056] Specifically, the indoor unit body 100 is provided with an oxygen outlet 110. The piping assembly 500 further includes a third pipe, the ends of which are connected to the oxygen production opening of the oxygen production assembly 400 and the oxygen outlet 110, respectively. At least a portion of the third pipe is disposed within the first pipe 510. This arrangement fully utilizes the space in the fresh air intake passage, reduces the installation space required for additional piping, and makes the air conditioner's installation layout more compact, making it easier to install in various indoor environments.

[0057] By arranging the third pipe part inside the first pipe 510, heat exchange and pressure loss during the transmission of oxygen from the oxygen production assembly 400 to the room can be reduced, thereby reducing energy consumption and improving the overall energy efficiency of the system.

[0058] The inner diameter of the first pipe 510 is D, and the inner diameter of the second pipe is D1; ​​where D / D1 ≥ 2. By setting the ratio D / D1 ≥ 2, the first pipe 510 has a sufficiently large inner diameter to allow for the introduction of sufficient outdoor fresh air. This not only meets the needs of indoor ventilation and oxygen replenishment, but also ensures that even if some fresh air is consumed during the oxygen production process, the fresh air assembly 300 can still provide sufficient fresh air volume to maintain indoor air circulation.

[0059] The smaller inner diameter of the second pipe 520 allows for more precise control of the amount of gas flowing to the oxygen generator 400, preventing gas waste during transmission. Because D / D1 ≥ 2, the gas required for oxygen production can be efficiently extracted directly from the fresh air, reducing pressure loss along the gas transmission path, improving oxygen production efficiency, and ensuring the required gas quality during the production process.

[0060] Because the first pipe 510 efficiently introduces a large amount of fresh air, while the second pipe 520 precisely controls the amount of gas flowing to the oxygen production assembly 400, this design reduces inefficient energy consumption. During the oxygen production process, the optimized gas transmission path reduces additional energy loss.

[0061] During the specific implementation process, the pipeline assembly 500 also includes: a limiting component 530, which is arranged in the first pipe fitting 510, and there is a limiting space in the limiting component 530. At least part of the second pipe fitting 520 and / or the third pipe fitting is arranged in the limiting space, so as to limit the second pipe fitting 520 and / or the third pipe fitting by the limiting component 530; wherein, at least part of the limiting component 530 can be elastically set, and there are multiple limiting components 530, and the multiple limiting components 530 are spaced apart along the extension direction of the first pipe fitting 510.

[0062] At least part of the limiting component 530 is made of elastic material and can be deformed appropriately according to the actual size of the second pipe 520 or the third pipe, thereby providing a tighter and more stable limiting effect, ensuring that the position of the pipe is fixed and the structure is stable during use, and reducing the risk of pipeline leakage caused by vibration or displacement.

[0063] Multiple limiting components 530 are arranged at intervals along the extension direction of the first pipe 510, and can limit the second pipe 520 at multiple points. Even if a limiting point is damaged or fails, other limiting components can still function, thereby improving the reliability and redundancy of the system.

[0064] The limiting component 530 can also provide certain physical protection for the second pipe 520 and / or the third pipe to prevent damage thereto by external factors (such as impact, corrosion), thereby extending the service life of the entire pipeline system.

[0065] In the present application, the material of the limiting component 530 is silicone, polytetrafluoroethylene, or EPDM rubber, etc., to ensure that it maintains good limiting performance under different temperature and humidity conditions, while avoiding limiting failure caused by material aging.

[0066] The retaining member 530 is an annular structure with an opening for the second pipe 520 and / or the third pipe to engage. The annular structure is embedded in the inner wall of the first pipe 510 to ensure stable positioning of the second pipe 520 and / or the third pipe. The retaining member 530 and the first pipe 510 are integrally injection-molded.

[0067] In the embodiment provided in the present application, the fresh air assembly 300 further includes: a filter component 310, which is arranged in the fresh air channel 301. After filtering the outdoor fresh air through the filter component 310, the outdoor fresh air flows into the room and into the second pipe 520 respectively. The use of a shared filter component 310 replaces the mode in which each independent component (fresh air, oxygen production) in the traditional air-conditioning system needs to be equipped with a filter screen, reducing the use of consumables, reducing operating costs, and simplifying the user's daily maintenance work. The integrated design of the filter component 310 and the fresh air assembly 300 reduces the installation space required for additional components, making the air conditioner more compact in structure and easier to install.

[0068] The filter set in the fresh air component 300 can serve the fresh air channel 301 and the oxygen production process at the same time, avoiding the need to equip the oxygen production component 400 with an additional filtering structure. This not only reduces the use of overall consumables and maintenance costs, but also improves the utilization rate of the filter.

[0069] In a new step, the fresh air component 300 includes: an installation body 320, which is arranged on the indoor body 100, and the fresh air channel 301 is arranged in the installation body 320; the first pipe 510 and the second pipe 520 are respectively connected to the installation body 320 to communicate with the fresh air channel 301.

[0070] The installation body 320 integrates the fresh air channel 301, and the docking method with the first pipe fitting 510 and the second pipe fitting 520 makes the entire air-conditioning system design more compact. The docking design of the first pipe fitting 510 and the second pipe fitting 520 with the installation body 320 avoids complicated wiring and pipeline assembly.

[0071] By being connected to the fresh air channel 301, the second pipe 520 can directly obtain preliminarily filtered air with the help of the fresh air introduced by the first pipe 510 for use in the subsequent oxygen production process, thereby achieving effective coordination between the fresh air and oxygen production functions and improving the overall efficiency of the system.

[0072] Specifically, a partition 330 is also provided in the installation body 320, which divides the fresh air channel 301 into a first channel 302 and a second channel 303; a connecting hole 331 is provided on the partition 330, and the first channel 302 and the second channel 303 are connected through the connecting hole 331; the first pipe fitting 510 is connected to the first channel 302, and the second pipe fitting 520 is connected to the second channel 303.

[0073] Partition 330 divides fresh air passage 301 into first passage 302 and second passage 303. A first pipe 510 connects to first passage 302, introducing fresh air. A second pipe 520 connects to second passage 303, allowing air to flow into the oxygen generator. This design ensures independent operation of the fresh air and oxygen generation functions. Furthermore, the connecting hole 331 allows them to work together when necessary, improving the flexibility and efficiency of the overall system.

[0074] In the present application, in addition to serving as an oxygen production channel, the second channel 303 can also reduce the noise of the fresh air flowing through the first channel 302. After the partition 330 divides the fresh air channel 301 into the first channel 302 and the second channel 303, the second channel 303 can serve as a silencer for the first channel 302 during the fresh air flowing through the first channel 302. When the airflow flows in the second channel 303, it will collide and diffuse with the air inside the cavity multiple times. This multiple reflection and diffusion effect can effectively attenuate the energy of the sound waves, thereby reducing the noise of the fresh air flow. Furthermore, it can also isolate the noise transmitted to the room by the air compressor through the second pipe 520.

[0075] Among them, a door panel is provided on the partition 330, and the door panel is slidably provided on the partition 330 to block or avoid the connecting hole 331, so as to realize a separate fresh air function or the fresh air function and the oxygen production function working together.

[0076] Furthermore, the connecting holes 331 on the partition 330 can precisely control the airflow exchange between the first channel 302 and the second channel 303. When the oxygen generator requires more fresh air, the size or opening of the connecting holes 331 can be adjusted, that is, the area blocked by the door panel from the connecting holes 331 can be adjusted to increase the fresh air supply to the second channel 303, and vice versa. This design helps achieve intelligent optimization of airflow and improve air quality.

[0077] By dividing the fresh air passage 301 into two independent passages that are connected through the connecting hole 331, the filter area can be more effectively utilized. When the second pipe 520 is turned on to inhale, the filtered fresh air not only meets the fresh air demand but also can be used for oxygen production, avoiding the need for additional filters during the oxygen production process and reducing consumables.

[0078] In the specific embodiment provided in the application, in order to reduce the noise generated by the fresh air in the process of flowing through the first channel 302, and at the same time prevent the noise of the outdoor air compressor during the oxygen production process from being transmitted to the indoor room, the partition 330 includes a first plate body 3301 and a second plate body 3302, and the first plate body 3301 and the second plate body 3302 are arranged at an angle to form a silencer cavity between the first plate body 3301, the second plate body 3302 and the inner wall surface of the fresh air channel 301; the connecting hole 331 includes a first connecting hole 3310 and a second connecting hole 3311, the first connecting hole 3310 is arranged on the first plate body 3301, and the second connecting hole 3311 is arranged on the second plate body 3302, and the airflow in the first channel 302 flows through the first connecting hole 3310, the silencer cavity and the second connecting hole 3311 in sequence before flowing into the second channel 303.

[0079] Among them, the design of the silencer chamber forms a buffer zone between the first channel 302 and the second channel 303. When the airflow flows in the silencer chamber, it will collide and diffuse with the air inside the chamber multiple times. This multiple reflection and diffusion effect can effectively attenuate the energy of the sound wave, thereby reducing the noise during the airflow process, and at the same time reducing the noise transmitted from the air compressor to the room through the second pipe 520.

[0080] Specifically, if Figures 8 to 10 As shown, there are multiple first connecting holes 3310 , which are spaced apart on the first plate 3301 ; and / or there are multiple second connecting holes 3311 , which are spaced apart on the second plate 3302 .

[0081] The design of multiple first connecting holes 3310 and / or multiple second connecting holes 3311 can disperse the airflow, making the gas more evenly distributed in the channel, avoiding the airflow concentration and turbulence that may be caused by a single large hole, and improving the airflow stability and efficiency of the entire system.

[0082] Preferably, the aperture of each first connecting hole 3310 is 1mm~3mm, the area where multiple first connecting holes 3310 are arranged is the first ventilation area, and the total area of ​​the first ventilation area accounts for more than 50% of the surface area of ​​the first plate 3301; and / or, the aperture of each second connecting hole 3311 is 1mm~3mm, the area where multiple second connecting holes 3311 are arranged is the second ventilation area, and the total area of ​​the second ventilation area accounts for more than 50% of the surface area of ​​the second plate 3302.

[0083] By limiting the aperture of the first connecting hole 3310 and / or the second connecting hole 3311 and utilizing the principle of micropore sound attenuation, multiple small holes can more effectively absorb and attenuate sound waves than a single large hole, reducing the noise generated when air flows through the connecting holes and providing a quieter user experience. When sound waves encounter the micropores, some are reflected by the pore walls, while others penetrate the pores and enter the interior. Due to the small pore volume, the sound waves are reflected and scattered multiple times within the pores, converted into heat energy and absorbed, thereby reducing noise intensity.

[0084] The air conditioner of the present application not only optimizes the airflow distribution and enhances the filtering and purification effects by arranging multiple spaced connecting holes on the plate body within the fresh air channel 301, but also significantly reduces the operating noise by utilizing the microporous silencer principle, thereby improving the user experience.

[0085] During the specific implementation process, the installation body 320 also includes a connecting member 340, one end of the connecting member 340 is connected to the first pipe 510, and the other end of the connecting member 340 is connected to the fresh air channel 301; along the flow direction of the airflow in the connecting member 340, the cross-sectional area of ​​the flow section of the connecting member 340 gradually increases.

[0086] The gradually increasing cross-sectional area of ​​the connector 340 helps reduce resistance encountered by air as it transitions from the first pipe 510 to the fresh air duct 301. The airflow gradually expands after passing through the narrow inlet, reducing flow velocity, eddies, and turbulence, thereby lowering noise and energy consumption as the air flows through the connector.

[0087] The gradual increase in the flow cross-sectional area helps to distribute the airflow more evenly on the filter component 310, avoids overload in local areas, and enhances the filtering effect. It also helps to make the airflow distribution of the entire fresh air component 300 more reasonable and improves the efficiency of fresh air introduction.

[0088] The gradually expanding flow cross-section design enables the connector 340 to better adapt to changes under different airflow conditions, and maintain good airflow stability and filtering effect even when the airflow speed is high or low, thereby enhancing the adaptability and stability of the air-conditioning system.

[0089] In the present application, the fresh air channel 301 has an outdoor air inlet 3010, an indoor air inlet 3011, a first air outlet 3012 and a second air outlet 3013. The first air outlet 3012 is connected to the indoor environment, and the second air outlet 3013 is connected to the second pipe 520. The fresh air component 300 also includes: a switching component 350, which is rotatably arranged between the outdoor air inlet 3010 and the indoor air inlet 3011, so that the outdoor air inlet 3010 and the indoor air inlet 3011 can be selectively connected to the fresh air channel 301.

[0090] Switching element 350 is rotatably positioned between outdoor air inlet 3010 and indoor air inlet 3011, allowing the user or an intelligent control system to selectively introduce fresh air from either the outside or the inside, depending on the current indoor and outdoor environmental conditions. This significantly enhances the adaptability and flexibility of the air conditioning system to various environments. This allows the air conditioner to intelligently adjust its fresh air introduction strategy based on the indoor and outdoor temperature difference and air quality, ensuring a comfortable indoor temperature while maintaining good air quality, thus enhancing the comfort of the living or office environment.

[0091] Under high or low outdoor temperature conditions, the outdoor air inlet 3010 can be closed, and fresh air can be introduced only through the indoor air inlet 3011 to reduce the additional energy consumption for temperature regulation. When the outdoor air quality is good, fresh air is introduced through the outdoor air inlet 3010 first to improve the efficiency of fresh air introduction and reduce energy consumption.

[0092] Furthermore, the fresh air channel 301 is provided with a first stop portion 304 and a second stop portion 305, the first stop portion 304 encloses the indoor air inlet 3011, and the second stop portion 305 encloses the outdoor air inlet 3010; the switching component 350 rotates to fit with the first stop portion 304 to block the indoor air inlet 3011; the switching component 350 rotates to fit with the second stop portion 305 to block the outdoor air inlet 3010.

[0093] By rotating the switching member 350 to engage the first stopper 304 or the second stopper 305, the opening and closing of the indoor air inlet 3011 and the outdoor air inlet 3010 can be flexibly controlled. This means that when indoor air quality meets standards or the external environment is adverse (such as smog, high temperatures, or low temperatures), the outdoor air inlet 3010 can be closed, prioritizing indoor air circulation. Conversely, when fresh air is needed, indoor circulation can be turned off and outdoor fresh air can be brought in, achieving intelligent switching of air circulation modes.

[0094] This mechanism selectively introduces fresh outdoor air or closes it off based on actual needs, reducing unnecessary energy consumption. This is especially true in extreme climates. By closing the outdoor air inlet 3010, the air conditioning system avoids the increased energy consumption associated with introducing large amounts of cold or hot outdoor air. When outdoor air quality is poor, closing the outdoor air inlet 3010 reduces the burden on the air filter, extending its lifespan and saving maintenance and consumables.

[0095] Specifically, the first stop portion 304 includes a first stop end surface 3040 , and the second stop portion 305 includes a second stop end surface 3050 . The plane where the first stop end surface 3040 is located and the plane where the second stop end surface 3050 is located form an acute angle.

[0096] The setting of the acute angle enables the first stop end face 3040 and the second stop end face 3050 to be arranged compactly in space, effectively utilizing the three-dimensional space inside the fresh air component 300 and reducing the volume of the overall component. Especially in the spatial layout of the indoor body 100, this design can save valuable installation space.

[0097] In the present application, the fresh air channel 301 includes a first channel 302 and a second channel 303 that are interconnected. The first channel 302 includes a first flow section 3020 and a second flow section 3021 that are interconnected. The indoor air inlet 3011, the outdoor air inlet 3010 and the first air outlet 3012 are respectively connected to the second flow section 3021; ​​the second air outlet 3013 is connected to the first flow section 3020; the first flow section 3020 is docked and connected to the first pipe fitting 510, and after the second pipe fitting 520 passes through the first pipe fitting 510, it passes through the first flow section 3020 and is connected to the second channel 303; wherein, the outdoor air inlet 3010 is located between the first flow section 3020 and the second flow section 3021.

[0098] The provision of the first channel 302 and the second channel 303 achieves physical isolation between the fresh air introduction and the oxygen production and inhalation functions, thereby ensuring that the two processes do not interfere with each other and improving the operating efficiency and controllability of the system.

[0099] The connection design between the first circulation section 3020 and the second circulation section 3021 allows outdoor fresh air to be initially buffered through the first circulation section 3020 before flowing into the second circulation section 3021 for in-depth processing. This progressive airflow path design helps to reduce airflow impact, improve filtration efficiency, and ensure indoor air quality.

[0100] The first pipe fitting 510 is docked with and connected to the first circulation section 3020, which not only undertakes the task of introducing fresh air, but also provides an exit channel for the second pipe fitting 520, so that the second pipe fitting 520 can be smoothly connected to the second channel 303, realizing the sharing of pipeline resources and the separation of functions, greatly improving the system integration, and simplifying the installation and maintenance process.

[0101] An air outlet passage 120 and an oxygen outlet 110 are provided in the indoor unit body 100 . The oxygen outlet 110 is provided on a passage wall of the air outlet passage 120 .

[0102] Oxygen is released directly into the air outlet 120 through the oxygen outlet 110, where it mixes with the normal air-conditioned air before being evenly distributed into the indoor environment. This design ensures rapid and uniform oxygen diffusion throughout the room, avoiding safety hazards caused by localized excessive oxygen concentrations. It also enhances user comfort and solves the problem of uneven indoor oxygen distribution caused by oxygen accumulation in small areas.

[0103] Integrating the oxygen outlet 110 on the wall of the air outlet duct 120 fully utilizes the existing space, avoids occupying additional installation space, and makes the internal structure of the air conditioner more compact and reasonable; due to the close integration of the oxygen outlet 110 and the air outlet duct 120, the air conditioner can achieve synchronous regulation of oxygen concentration and indoor temperature through a single control system.

[0104] The integrated design of the oxygen outlet 110 and the air outlet duct 120 simplifies the installation process of the indoor unit 100 , avoids the layout of additional pipes, reduces the installation difficulty, and reduces the installation time and cost.

[0105] The present application also provides an air conditioner control method applicable to the air conditioner of the above embodiment, wherein the rotation speed of the fresh air component 300 of the air conditioner is divided into a first fresh air speed and a second fresh air speed from low to high; the rotation speed of the oxygen production component 400 is divided into a first oxygen production speed and a second oxygen production speed from low to high; the air conditioner control method includes:

[0106] Acquire outdoor environmental information, which includes at least: outdoor ambient temperature and outdoor air quality;

[0107] According to the outdoor environment information, the fresh air component 300 is controlled to operate at the first fresh air speed and the oxygen production component 400 is controlled to operate at the second oxygen production speed; or

[0108] The fresh air component 300 is controlled to operate at the second speed of fresh air, and the oxygen production component 400 is controlled to operate at the first speed of oxygen production.

[0109] The control method adjusts the speed of the fresh air and oxygen generator components in real time based on outdoor ambient temperature and air quality. Under harsh outdoor conditions (such as low temperatures, high temperatures, and high PM2.5 concentrations), the combination of high-speed oxygen generation and low-speed fresh air introduction prioritizes maintaining indoor oxygen concentration while minimizing the adverse effects of introducing harsh outdoor air on the indoor environment.

[0110] When the outdoor environment is suitable, the configuration of high-speed fresh air introduction and low-speed oxygen production can introduce fresh air more efficiently and reduce energy consumption in the oxygen production process, thereby achieving energy savings while ensuring indoor air quality. By controlling the speed of fresh air and oxygen production components, they can be accurately adjusted according to the actual needs of indoor air quality, avoiding unnecessary excessive ventilation or oxygen production, ensuring that indoor air quality is always in the best condition, and improving the operating efficiency of the air-conditioning system and user satisfaction.

[0111] The control method also includes:

[0112] Establishing a first temperature threshold, a second temperature threshold, and a third temperature threshold, wherein the first temperature threshold, the second temperature threshold, and the third temperature threshold gradually increase;

[0113] When the outdoor ambient temperature is at the first temperature threshold or the third temperature threshold, the fresh air component 300 is controlled to operate at the first fresh air speed, and the oxygen production component 400 is controlled to operate at the second oxygen production speed;

[0114] When the outdoor ambient temperature is at the second temperature threshold, the fresh air component 300 is controlled to operate at the second fresh air speed, and the oxygen production component 400 is controlled to operate at the first oxygen production speed.

[0115] By setting the first, second, and third temperature thresholds, the air conditioner can intelligently adjust the operating speed of the fresh air and oxygen generator components according to subtle changes in outdoor temperature, achieving dual management of indoor temperature and air quality. Compared with fixed-mode operation, this method can more accurately match the user's indoor environment needs.

[0116] When the outdoor temperature is extremely low (below the first temperature threshold) or extremely high (above the third temperature threshold), the fresh air introduction rate is reduced (the first fresh air speed setting) to avoid introducing large amounts of air at extreme temperatures, thereby reducing the air conditioning system's energy consumption for temperature regulation. When the outdoor temperature is mild (near the second temperature threshold), the fresh air introduction rate is accelerated (the second fresh air speed setting) while the oxygen production rate is reduced, ensuring the freshness of the indoor air while maximizing energy savings.

[0117] By matching the temperature threshold setting with the component rotation speed, this control method can maintain indoor air quality under different outdoor temperature environments while taking into account human comfort, avoiding drastic changes in indoor temperature and humidity caused by excessive fresh air introduction or oxygen production, and providing users with a more comfortable and healthy living or office environment.

[0118] Preferably, the first temperature threshold is the outdoor temperature H≤0°C, the second temperature threshold is 0°C<H<30°C, and the third temperature threshold is the outdoor temperature H≥30°C.

[0119] The control method also includes:

[0120] establishing a first quality threshold and a second quality threshold, wherein the first quality threshold is lower than the second quality threshold;

[0121] When the outdoor air quality is at the second quality threshold, the fresh air component 300 is controlled to operate at the first fresh air speed, and the oxygen production component 400 is controlled to operate at the second oxygen production speed;

[0122] When the outdoor air quality is at the first quality threshold, the fresh air component 300 is controlled to operate at the second fresh air speed, and the oxygen production component 400 is controlled to operate at the first oxygen production speed.

[0123] The first and second quality thresholds allow the air conditioner to automatically adjust its fresh air and oxygen production modes based on different outdoor air quality levels. When outdoor air quality is high, fresh air is introduced at a lower rate while oxygen production is enhanced to ensure a high indoor oxygen concentration. When outdoor air quality is poor, the fresh air rate is increased to dilute potentially contaminated indoor air while oxygen production is reduced to avoid introducing excessive amounts of impure outdoor air.

[0124] The air conditioner and control method of the present application combine the fresh air function with the oxygen production function by designing the fresh air component into a dual air duct and the air duct into a dual-channel air duct, thereby saving space and simplifying installation, and avoiding the problem of multiple pipes running together, which require complicated pipe arrangement, wrapping and hole expansion before they can pass through the wall. The oxygen production intake pipe opening (i.e., the second air outlet 3013) is designed to be in the air inlet chamber of the fresh air fan and share the filter with the fresh air fan to reduce the use of consumables. At the same time, the oxygen production intake pipe path is reduced, and the oxygen production efficiency is improved. By utilizing the characteristic of the fresh air component that is always under positive pressure, the fresh air required for oxygen production can be ensured without the need for additional dampers. Reducing parts simplifies production and improves reliability, while saving space makes it easier to design miniaturized components. The synchronous intelligent control design makes the air conditioner more energy-efficient and the filter has a longer service life;

[0125] The oxygen generator is designed to be placed on the outer casing and share the same casing with the air conditioner outer casing; the fresh air component is designed in the air conditioner inner unit, and the oxygen outlet is designed on the left side of the inner unit air outlet; the fresh air component is designed with dual air ducts, namely the first channel 302 and the second channel 303; the air duct is designed as a dual-channel air duct, namely the first pipe fitting 510 is sleeved on the second pipe fitting 520, and the ratio of the inner diameter D of the first pipe fitting 510 to the outer diameter D1 of the second pipe fitting 520 is greater than or equal to 2, namely D / D1 ≥ 2, which meets the oxygen production intake demand while ensuring the fresh air volume; the air duct space and the size setting of the oxygen production air pipe are used to construct a dual-channel air duct, which meets both the fresh air demand and the oxygen production intake demand, thereby simplifying the installation; solving the problem of multiple pipe wrapping and additional drilling required for the simultaneous routing of the fresh air pipe and the oxygen production pipe; saving more space and making the installation simpler.

[0126] The oxygen production intake pipe is designed to be inside the air inlet chamber of the fresh air blower and share the filter with the fresh air blower to reduce the use of consumables. At the same time, the oxygen production intake pipe path is reduced to improve the oxygen production efficiency; the oxygen production intake path is reduced to improve the oxygen production efficiency, while avoiding the addition of additional filters and reducing the consumption of consumables. The combination of fresh air and oxygen production can achieve multiple state adjustments, making the improvement of air quality smarter and more efficient. It solves the problem of needing to add an additional filter at the end of the oxygen production equipment intake pipe, solves the problem of the oxygen production equipment intake pipe being too long, and solves the problem of the fresh air components and oxygen production equipment being installed at the same time and taking up too much space. It effectively combines the fresh air function and the oxygen production function, and is more efficient and smarter to use to improve indoor air quality. At the same time, it facilitates installation, reduces consumables, and saves maintenance costs.

[0127] By leveraging the constant positive pressure of the fresh air component, the fresh air required for oxygen production can be ensured without the need for additional dampers. Reducing the number of parts simplifies production, improving reliability, while also saving space and facilitating component miniaturization. By leveraging the positive pressure within the fresh air blower's air chamber, the oxygen generator ensures that only outdoor air is drawn in without the need for additional dampers. This eliminates the need for additional dampers when integrating the oxygen generator's intake duct with the fresh air supply. This simplifies production, improves production throughput, saves space, and enhances product reliability.

[0128] When the fresh air blower is turned on, it draws fresh air from outside into the room through the fresh air duct. The air passes through the filter inside the blower, removing impurities from the air, ensuring air cleanliness. The fresh air blower's air chamber is always under positive pressure during operation. When the oxygen generator is turned on, it directly supplies clean air to the oxygen generator through another air duct of the fresh air blower and the air pipe designed inside the air duct, ensuring that the air is clean air from outside. This also reduces the oxygen inhalation path and improves oxygen production efficiency. The combination of fresh air and oxygen production enables multi-state adjustment, making air quality improvement more intelligent and efficient.

[0129] During use, when the air conditioner is turned on, the sensors on the air conditioner begin to collect the temperature and air quality conditions of the outdoor environment.

[0130] When the outdoor temperature is H:0°C ≥ H or H ≥ 30°C; or when the outdoor air PM2.5 exceeds the programmed value, the fresh air blower will run at a low speed to ensure positive pressure inside the blower to provide clean air to the oxygen generator, while the oxygen generator will run at a high speed to maintain the indoor oxygen concentration. This prevents the low (high) temperature outdoor air from significantly affecting indoor problems, or reduces the rapid wear of the filter caused by poor outdoor air quality.

[0131] When the outdoor temperature H:0 degrees < H or H < 30 degrees; or the outdoor air PM2.5 is less than the program setting value, the fresh air fan runs at high speed and the oxygen production equipment runs at low speed, improving the efficiency of indoor air quality, ensuring the stability of indoor oxygen concentration, and reducing the loss of oxygen production equipment.

[0132] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0133] The air conditioner provided in the present application has an indoor body 100 including a fresh air component 300, which has a fresh air duct 301 therein; an outdoor body 200 including an oxygen production component 400 for providing oxygen to the indoor room; a first pipe 510 and a second pipe 520 are provided; one end of the first pipe 510 is used to communicate with the outdoor environment, and the other end of the first pipe 510 is communicated with the fresh air duct 301 to introduce outdoor fresh air into the fresh air duct 301; the two ends of the second pipe 520 are respectively communicated with the fresh air duct 301 and the oxygen production component 400, so that part of the outdoor fresh air in the fresh air duct 301 is discharged into the indoor room, and the other part is transported to the oxygen production component 400 through the second pipe 520 for oxygen production, wherein at least a portion of the first pipe 510 is sleeved on the second pipe 520. This configuration combines the air conditioner's fresh air function with its oxygen production function, utilizing outdoor fresh air to provide an air source for the oxygen production assembly 400. This eliminates the need for a separate outdoor piping structure for air intake and oxygen production. This design significantly reduces the number of external piping, simplifies the air conditioner's installation process, and saves installation space. The air conditioner of this application can simultaneously meet the needs of fresh air ventilation and oxygen replenishment, effectively improving indoor air quality. The introduction of fresh air ensures the circulation and freshness of indoor air, while the oxygen production function ensures sufficient indoor oxygen content. Together, these functions create a healthier indoor environment.
