Description

Technical Field

[0001] This utility model relates to the field of oxygen-generating air conditioning technology, and more specifically, to an air conditioner with an oxygen-generating device. Background Technology

[0002] In modern homes and offices, air quality and breathing comfort have become increasingly important concerns. With technological advancements, fresh air conditioning systems are widely used for indoor air circulation and purification, effectively improving air quality in living and working spaces. However, traditional air conditioning systems, while introducing fresh outdoor air, often neglect to increase the oxygen concentration in indoor air. This can mean insufficient breathing comfort and health for people who need to work or rest indoors for extended periods, especially residents of high-altitude areas.

[0003] To address this issue, oxygen-generating air conditioners have emerged. These air conditioners integrate an oxygen-generating device into a regular air conditioner, effectively increasing indoor oxygen concentration and creating a slightly oxygen-rich environment, thereby significantly improving indoor air quality and human respiratory comfort.

[0004] Most existing oxygen-generating air conditioners use air compressors to compress air and then use molecular sieve technology to separate oxygen and nitrogen from the air, thus providing a high concentration of oxygen for users to breathe. However, as the core component of the oxygen-generating module, the air compressor often generates considerable noise during operation, significantly disturbing the user's living environment and reducing the user experience.

[0009] Furthermore, the oxygen generating device also includes: a third connecting pipe, the two ends of which are respectively connected to the first oxygen outlet and the first oxygen channel; and a third one-way valve, which is installed on the third connecting pipe and connected to the third connecting pipe.

[0010] Furthermore, the oxygen generating device also includes: a third chamber disposed to the side of the second chamber; and a second movable component disposed within the third chamber to divide the third chamber into a second air passage and a second oxygen passage, wherein the two ends of the second air passage are respectively connected to a fresh air outlet and an air inlet, and the second oxygen passage is respectively connected to a first oxygen outlet and indoor air.

[0011] Furthermore, the oxygen generating device also includes a driving component, which includes two driving rods connected to the first moving member and the second moving member respectively, so as to drive the first moving member and the second moving member to move simultaneously through the driving component.

[0012] Furthermore, the oxygen generating device also includes: a first connecting joint, which is provided with a first air outlet channel, a first air inlet channel and a second air inlet channel, the first air inlet channel and the second air inlet channel being respectively connected to the first air outlet channel; the first air outlet channel is connected to an air inlet, the first air inlet channel is connected to a first air channel, and the second air inlet channel is connected to a second air channel.

[0013] Furthermore, the oxygen generating device also includes: a second connecting joint, which is provided with a third air inlet channel, a second air outlet channel and a third air outlet channel, the second air outlet channel and the third air outlet channel being connected to the third air inlet channel respectively; the third air inlet channel is connected to the first oxygen outlet, the second air outlet channel is connected to the first oxygen channel, and the third air outlet channel is connected to the second oxygen channel.

[0014] Furthermore, the oxygen purification component is annular to form an oxygen purification chamber, which is connected to the first oxygen channel; there is an airflow gap between the oxygen purification component and the inner wall of the first chamber, and the nitrogen separated by the oxygen purification component is discharged through the airflow gap.

[0015] Furthermore, the oxygen generating device also includes a nitrogen venting pipe, one end of which is connected to the flow interval and the other end extends to the outside, so that the nitrogen separated by the oxygen purification component can be discharged to the outside through the nitrogen venting pipe.

[0016] Furthermore, the fresh air device includes a fresh air duct for introducing outdoor fresh air into the room; wherein at least a portion of the nitrogen exhaust duct is inserted within the fresh air duct.

[0017] Furthermore, the fresh air device includes a fresh air duct and a nitrogen exhaust duct. The fresh air duct is connected to the fresh air duct, and the nitrogen exhaust duct includes a first pipe section and a second pipe section. The two ends of the first pipe section are connected to the air inlet of the flow interval and the nitrogen exhaust duct, respectively. The two ends of the second pipe section are connected to the exhaust outlet of the nitrogen exhaust duct and the outdoor air, respectively. The second pipe section passes through the fresh air duct and then enters the fresh air duct.

The first chamber houses an oxygen purification component for separating oxygen from the air. The second chamber contains a first movable component that moves along the inner wall of the chamber, thus creating two independent areas within the second chamber—a first air channel and a first oxygen channel. Fresh air enters the first air channel of the second chamber through the fresh air outlet. Subsequently, through the movement of the first movable component, the air is guided to the air inlet of the first chamber. Upon entering the first chamber, the air contacts the oxygen purification component, and oxygen is separated. The separated oxygen flows through the first oxygen outlet of the first chamber. When the first movable component moves in the opposite direction, the oxygen is introduced into the first oxygen channel of the second chamber, and then, through communication with the indoor air, the oxygen is directly discharged into the indoor space, achieving immediate oxygen supply.

[0021] This application eliminates the need for an additional air compressor. By utilizing the piston effect of the first moving part, the noise level during equipment operation is greatly reduced.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] As mentioned in the background section, in the current air conditioning technology field, especially for oxygen-generating air conditioning technology aimed at improving indoor air quality, traditional oxygen-generating modules typically include key components such as an air compressor, molecular sieves, and inlet filter materials. These modules work by compressing air with an air compressor and then using molecular sieve technology to separate oxygen and nitrogen from the air, thereby providing a high concentration of oxygen for users to breathe. Although this technology can effectively increase indoor oxygen levels, the air compressor, as the core component of the oxygen-generating module, often generates considerable noise during operation, especially at night or in quiet environments, which can significantly disturb the user's living environment. Therefore, to address the aforementioned technical problems, the oxygen generating device provided in this application is connected to the fresh air outlet 210 of the fresh air device 200. The oxygen generating device includes: a first chamber 310 and a second chamber 320. An oxygen purification component 311 is disposed in the first chamber 310, and the first chamber 310 has an air inlet 312 and a first oxygen outlet 313. A first movable component 321 is disposed in the second chamber 320 to divide the second chamber 320 into a first air channel 322 and a first oxygen channel 323. The two ends of the first air channel 322 are respectively connected to... The fresh air outlet 210 and air inlet 312 are connected, and the first oxygen channel 323 is connected to the first oxygen outlet 313 and the indoor air respectively. The position of the first moving member 321 is movable so that when the first moving member 321 moves in the first direction, the fresh air in the fresh air outlet 210 is introduced into the first chamber 310 through the first air channel 322. The oxygen in the fresh air is separated by the oxygen purification component 311. Then, the oxygen is introduced into the first oxygen channel 323 and discharged into the room by the first moving member 321 moving in the opposite direction. The coordinated operation of the oxygen generating device and the fresh air device of this application enables the oxygen generating system to directly utilize filtered fresh air, avoiding the energy consumption and efficiency loss caused by traditional air compressors. By using the first moving member 321 as a power source instead of an air compressor to provide the required negative pressure and airflow, the operating noise is significantly reduced.

[0048] Please refer to Figures 1 to 4This application provides an oxygen generating device for communication with the fresh air outlet 210 of a fresh air device 200. The oxygen generating device includes: a first chamber 310 and a second chamber 320. An oxygen purification component 311 is disposed in the first chamber 310, and the first chamber 310 has an air inlet 312 and a first oxygen outlet 313. A first movable component 321 is disposed in the second chamber 320 to divide the second chamber 320 into a first air passage 322 and a first oxygen passage 323. The two ends of the first air passage 322 are respectively connected to the fresh air outlet. The inlet 210 is connected to the air inlet 312, and the first oxygen channel 323 is connected to the first oxygen outlet 313 and the indoor air respectively. The position of the first moving member 321 is movably set so that when the first moving member 321 moves in the first direction, the fresh air in the fresh air outlet 210 is introduced into the first chamber 310 through the first air channel 322, the oxygen in the fresh air is separated by the oxygen purification component 311, and then the oxygen is introduced into the first oxygen channel 323 and discharged into the room by the first moving member 321 moving in the opposite direction.

[0049] The oxygen generator mainly consists of a first chamber 310 and a second chamber 320. The first chamber 310 houses an oxygen purification component 311 for separating oxygen from the air. The second chamber 320 contains a first movable component 321, which moves along the inner wall of the chamber, thus forming two independent areas within the second chamber—a first air passage 322 and a first oxygen passage 323. Fresh air enters the first air passage 322 of the second chamber 320 through the fresh air outlet 210. Subsequently, through the movement of the first movable component 321, the air is guided to the air inlet 312 of the first chamber 310. Upon entering the first chamber 310, the air contacts the oxygen purification component 311, and oxygen is separated. The separated oxygen flows through the first oxygen outlet 313 of the first chamber 310. When the first movable component 321 moves in the opposite direction, the oxygen is introduced into the first oxygen passage 323 of the second chamber 320, and then, through communication with the indoor air, the oxygen is directly discharged into the indoor space, achieving immediate oxygen supply.

[0050] This application eliminates the need for an additional air compressor. By utilizing the piston effect of the first moving part 321, the noise level during equipment operation is greatly reduced. The oxygen purification component 311 acts directly on fresh air, thereby improving the efficiency of oxygen purification.

[0051] The oxygen generating device 300 includes a second housing that forms a second chamber. The second housing is provided with a second oxygen outlet 324 that communicates with the first oxygen channel 323 and faces the interior.

[0052] Specifically, the oxygen generating device further includes: a first connecting pipe 330, the two ends of which are connected to the fresh air outlet 210 and the first air passage 322 respectively; and a first one-way valve, which is installed on the first connecting pipe 330 and connected to the first connecting pipe 330.

[0053] The first one-way valve ensures that airflow can only flow in one direction from the fresh air outlet 210 to the first air passage 322, preventing backflow and thus ensuring the smooth progress of the oxygen purification process. The presence of the one-way valve effectively prevents internal gases (such as the separated oxygen) from flowing back into the external environment.

[0054] The first connecting pipe 330 serves as a bridge between the fresh air outlet 210 and the first air passage 322, ensuring that fresh air can be stably and continuously introduced into the oxygen generator without being affected by changes in the position of the first moving part 321.

[0055] The oxygen generating device also includes: a second connecting pipe 340, the two ends of which are connected to the first air passage 322 and the first chamber 310 respectively; and a second one-way valve, which is disposed on the second connecting pipe 340 and connected to the second connecting pipe 340.

[0056] The addition of the second connecting pipe 340 and the second one-way valve ensures that the air introduced from the fresh air outlet 210 into the first air passage 322 can flow smoothly into the first chamber 310 without backflow. The one-way valve design ensures that the gas can only flow in a predetermined direction, which is crucial for the stability and efficiency of the gas separation and purification process.

[0057] The addition of a one-way valve enhances the safety of the oxygen generation system. Under no circumstances will the oxygen produced during the oxygen generation process flow back into the fresh air system or the external environment, avoiding the potential risk of oxygen leakage and protecting user safety.

[0058] The oxygen generating device also includes: a third connecting pipe 350, the two ends of which are connected to the first oxygen outlet 313 and the first oxygen channel 323 respectively; and a third one-way valve, which is installed on the third connecting pipe 350 and connected to the third connecting pipe 350.

[0059] The design of the third one-way valve ensures that the purified oxygen from the first chamber 310 can smoothly enter the first oxygen channel 323, while preventing reverse airflow, avoiding mixing of oxygen with unpurified air, and ensuring the purity and supply quality of oxygen.

[0060] The third connecting pipe 350 serves as a direct channel for oxygen from the first chamber 310 to the first oxygen channel 323, simplifying the oxygen flow path, reducing energy loss during oxygen transmission, and greatly improving the efficiency of oxygen purification and delivery.

[0061] By setting up a third connecting pipe 350 and a third one-way valve, the maintenance and inspection of the oxygen purification system are made more convenient, because these two components are independent and can be maintained or replaced separately without interrupting the oxygen production process.

[0062] In the embodiments provided in this application, the oxygen generating device further includes: a third chamber 360 disposed to the side of the second chamber 320; and a second movable member 361 disposed in the third chamber 360 to divide the third chamber 360 into a second air passage 362 and a second oxygen passage 363. The two ends of the second air passage 362 are respectively connected to the fresh air outlet 210 and the air inlet 312, and the second oxygen passage 363 is respectively connected to the first oxygen outlet 313 and the indoor air.

[0063] The addition of the third chamber 360 complements the existing first chamber 310 and second chamber 320, increasing the oxygen purification and delivery capacity of the device. Through the movement of the second moving part 361, air can be more effectively introduced into the oxygen purification component 311, and the purified oxygen can be rapidly delivered into the room through the second oxygen channel 363, thereby significantly improving the overall oxygen production and efficiency.

[0064] The second movable component 361 moves within the third chamber 360, and can stably control the gas flow in the second air passage 362 and the second oxygen passage 363.

[0065] The addition of the third chamber 360 and the second moving part 361, combined with the second chamber 320 and the first moving part 321, not only enhances the oxygen production capacity of the oxygen generating device, but also improves the system's operating efficiency, stability and safety, providing users with a more efficient, healthy and comfortable living environment.

[0066] The oxygen generating device 300 also includes a third housing, which forms a third chamber 360. The third housing is provided with a third oxygen outlet 364 that communicates with the second oxygen channel 363 and faces the room.

[0067] In the specific implementation process, the oxygen generating device also includes a driving component 370, which includes two driving rods. The two driving rods are respectively connected to the first moving part 321 and the second moving part 361, so as to drive the first moving part 321 and the second moving part 361 to move simultaneously through the driving component 370.

[0068] By simultaneously driving the first moving part 321 and the second moving part 361 through the driving component 370, the air circulation and oxygen purification processes in the two chambers are synchronized, which greatly improves oxygen production efficiency. Because the two moving parts move synchronously, the intake of air and the exhaust of oxygen can be precisely controlled, unnecessary waiting time is avoided, and continuous gas processing and oxygen supply are ensured.

[0069] By using a single drive unit 370 to control the movement of two moving parts, this design simplifies the control system and reduces control complexity compared to controlling each moving part independently. This not only reduces the number of control components and lowers equipment costs, but also reduces potential control errors and improves system stability and reliability.

[0070] In this application, as Figure 3 As shown, the oxygen generating device further includes: a first connecting joint 380, which is provided with a first air outlet channel 381, a first air inlet channel 382 and a second air inlet channel 383, the first air inlet channel 382 and the second air inlet channel 383 being connected to the first air outlet channel 381 respectively; the first air outlet channel 381 is connected to the air inlet 312, the first air inlet channel 382 is connected to the first air channel 322, and the second air inlet channel 383 is connected to the second air channel 362.

[0071] The first connecting joint 380 is a key component connecting the first chamber 310, the second chamber 320 and the third chamber 360. The first air intake channel 382 is connected to the first air channel 322, the second air intake channel 383 is connected to the second air channel 362, and the first air outlet channel 381 is connected to the air inlet 312. This achieves efficient integration of gas flow and makes the circulation path of air before and after purification clearer and more orderly.

[0072] The gas channel design of the first connecting joint 380 allows for precise control of gas separation and flow. The first inlet channel 382 and the second inlet channel 383 introduce unpurified air into different chambers, while the first outlet channel 381 discharges oxygen separated from the first chamber 310, ensuring continuous oxygen production and supply.

[0073] Furthermore, the oxygen generating device also includes: a second connecting joint 390, which is provided with a third air inlet channel 391, a second air outlet channel 392 and a third air outlet channel 393, the second air outlet channel 392 and the third air outlet channel 393 being connected to the third air inlet channel 391 respectively; the third air inlet channel 391 being connected to the first oxygen outlet 313, the second air outlet channel 392 being connected to the first oxygen channel 323, and the third air outlet channel 393 being connected to the second oxygen channel 363.

[0074] In the oxygen generator, the second connecting connector 390 is a key component connecting the first chamber 310, the second chamber 320, and the third chamber 360. It internally houses three gas channels: a third inlet channel 391, a second outlet channel 392, and a third outlet channel 393. The arrangement and connection of these channels ensure precise and controllable gas flow paths during oxygen purification and delivery. Specifically:

[0075] The third air intake channel 391 is connected to the first oxygen outlet 313 and receives purified oxygen from the first chamber 310.

[0076] The second air outlet channel 392 is connected to the first oxygen channel 323, delivering oxygen to the pure oxygen chamber of the second chamber 320, and then to the indoor unit of the air conditioner for the user to breathe.

[0077] The third exhaust channel 393 is connected to the second oxygen channel 363, guiding some oxygen to the pure oxygen chamber of the third chamber 360 to ensure sufficient and stable oxygen output.

[0078] The drive unit 370 achieves efficient and stable oxygen purification and delivery by synchronously operating the first moving part 321 and the second moving part 361, in conjunction with the gas channel switching in the second connecting joint 390. For example, during the oxygen purification stage, the oxygen generated in the first chamber 310 enters the second connecting joint 390 through the third air inlet channel 391. Subsequently, depending on the positions of the first moving part 321 and the second moving part 361, the oxygen is guided to the most suitable output path (the second air outlet channel 392 or the third air outlet channel 393) to meet the indoor oxygen demand at different times.

[0079] In this application, the oxygen purification component 311 is annular to form an oxygen purification chamber 3110, which is connected to the first oxygen channel 323. There is an airflow gap 314 between the oxygen purification component 311 and the inner wall of the first chamber 310, and the nitrogen separated by the oxygen purification component 311 is discharged through the airflow gap 314.

[0080] The oxygen purification component 311 is designed as a ring, forming an oxygen purification chamber 3110. This structure maximizes the contact area between oxygen and the internal chamber, thereby improving the oxygen purification efficiency. Oxygen molecules in the air can more easily pass through the oxygen-enriched membrane into the chamber, while nitrogen molecules are blocked and discharged through the airflow gap 314, ensuring the high efficiency of the purification process.

[0081] The airflow gap 314 between the annular oxygen purification component 311 and the inner wall of the first chamber 310 provides a clear exhaust path for nitrogen, preventing nitrogen from stagnating in the chamber and affecting the quality and speed of oxygen purification. This is beneficial for achieving purer oxygen production.

[0082] The annular oxygen purification component 311 reduces the resistance to gas flow, making the air circulation in the chamber smoother and reducing the workload of the drive component 370, thereby reducing the overall energy consumption of the oxygen generator and making it more energy-efficient during operation.

[0083] In this application, the oxygen generating device 300 also includes a first housing, which forms a first chamber 310, and the oxygen purification component 311 is an oxygen-enriching membrane, which is connected to the first housing.

[0084] It should be noted here that the oxygen purification chamber 3110 is the chamber used to gather oxygen after separation by the oxygen purification component 311.

[0085] The oxygen generating device also includes a nitrogen venting pipe 400, one end of which is connected to the flow interval 314 and the other end extends to the outside, so that the nitrogen separated by the oxygen purification component 311 can be discharged to the outside through the nitrogen venting pipe 400.

[0086] The nitrogen venting fitting 400 is an important component, responsible for venting the nitrogen separated from the oxygen purification component 311 to the outside, thereby avoiding the negative impacts that may be caused by nitrogen accumulation indoors.

[0087] The nitrogen venting fitting 400 ensures that nitrogen can be discharged outdoors in a timely and effective manner, avoiding an excessively high proportion of nitrogen in the indoor air, thereby ensuring an increase in indoor oxygen concentration. The nitrogen venting fitting 400 is designed with unidirectional or directional gas discharge in mind. This design prevents nitrogen from flowing back into the oxygen generation system or the room, avoids the re-mixing of nitrogen and oxygen, protects the normal working condition of the oxygen purification component 311, and improves the purity of oxygen.

[0088] Furthermore, the fresh air device 200 includes a fresh air duct 220 for introducing outdoor fresh air into the room; wherein at least a portion of the nitrogen exhaust duct 400 passes through the fresh air duct 220.

[0089] By inserting at least a portion of the nitrogen venting pipe 400 inside the fresh air duct 220, heat exchange between nitrogen and fresh air can be promoted during the nitrogen venting process. During nitrogen venting, as nitrogen is discharged from indoors to outdoors, it comes into contact with the introduced fresh air inside the duct, which can effectively reduce the temperature of the fresh air and reduce the cooling energy consumption of the air conditioner when handling fresh air. At the same time, the pre-cooled fresh air also helps to stabilize the indoor temperature and humidity.

[0090] The integrated design of the nitrogen exhaust pipe fitting 400 and the fresh air pipe fitting 220 effectively utilizes the internal space of the fresh air duct, avoids the installation of additional nitrogen exhaust pipes, reduces the indoor and wall space occupied by the pipes, and makes the entire system layout more compact and easier to install.

[0091] Before being introduced into the room, the low-temperature fresh air undergoes heat exchange with the higher-temperature exhaust nitrogen airflow, which can effectively increase the temperature of the fresh air, reduce the temperature difference between the fresh air and the indoor air, prevent condensation on the inner wall of the fresh air duct, keep the indoor air dry, and avoid problems such as mold growth and corrosion caused by water accumulation in the duct.

[0092] In the embodiments provided in this application, the fresh air device 200 includes a fresh air duct 230 and a nitrogen exhaust duct 240. The fresh air duct 220 is connected to the fresh air duct 230. The nitrogen exhaust duct 400 includes a first pipe section 410 and a second pipe section 420. The two ends of the first pipe section 410 are respectively connected to the flow interval 314 and the air inlet of the nitrogen exhaust duct 240. The two ends of the second pipe section 420 are respectively connected to the exhaust port of the nitrogen exhaust duct 240 and the outdoor air. The second pipe section 420 passes through the fresh air duct 230 and then enters the fresh air duct 220.

[0093] The integrated design of the fresh air unit 200 and the nitrogen exhaust pipe 400, especially the docking method of the first pipe section 410 and the second pipe section 420 with the fresh air channel 230 and the nitrogen exhaust channel 240, maximizes the space utilization efficiency and avoids the space waste caused by multiple parallel pipes in the traditional design, making the whole equipment smaller and easier to install and arrange.

[0094] The second duct section 420 passes through the fresh air duct 230 and then enters the fresh air fitting 220. This design allows for effective heat exchange between the exhaust nitrogen and the fresh air in the same duct. The waste heat of the exhaust nitrogen is used to preheat the fresh air, reducing energy loss and improving energy efficiency. Especially in cold weather conditions, it can effectively prevent the indoor temperature from dropping due to excessively cold fresh air and maintain a comfortable indoor temperature.

[0095] like Figures 5 to 13 This application also provides an air conditioner, including an indoor unit 100, a fresh air device 200 and an oxygen generating device 300, wherein the fresh air device 200 and the oxygen generating device 300 are respectively disposed on the indoor unit 100, and the oxygen generating device is the oxygen generating device 300 of the above embodiment.

[0096] The indoor unit 100 is also provided with a panel 110 and an indoor fan 120. At least a portion of the oxygen generating device 300 is disposed between the panel 110 and the indoor fan 120. The oxygen outlet of the oxygen generating device 300 is oriented toward the indoor fan 120 so that oxygen is blown into the room under the guiding action of the indoor fan 120.

[0097] By placing at least a portion of the oxygen generator 300 between the panel 110 and the indoor fan 120, the unused space inside the air conditioner indoor unit 100 is cleverly utilized, avoiding the need for additional equipment installation space, making the overall design of the air conditioner more compact and improving space utilization.

[0098] The oxygen outlet of the oxygen generator 300 is positioned towards the indoor fan 120, allowing the purified oxygen to be directly and quickly and evenly blown into the room using the guiding effect of the indoor fan 120, without the need for additional oxygen delivery equipment or pipelines, thus improving the efficiency and speed of oxygen delivery.

[0099] The oxygen outlet is directly connected to the indoor fan 120, using its existing power source for oxygen transmission, avoiding additional energy consumption. For example, there is no need to add a power pump or fan to push oxygen, making the oxygen production process more energy-efficient and efficient.

[0100] Oxygen is directly and evenly dispersed by the indoor fan at 120°C, which can quickly increase the indoor oxygen concentration and create a comfortable and healthy living environment.

[0101] The air conditioner of this application has an oxygen generation system designed under the indoor unit panel that does not require an additional oxygen delivery pipe and does not damage the appearance of the air conditioner; it uses a gas separation membrane (oxygen-enriched membrane) to purify oxygen; it does not require an air compressor, but uses piston motion between two chambers to provide negative pressure to the purification system to purify oxygen.

[0102] The piston motion between the two chambers provides an airflow to the purification system to blow nitrogen molecules off the separation membrane.

[0103] The oxygen generation system shares a filter with the air conditioning fresh air components to ensure that the air entering the purification system is clean and dust-free.

[0104] The nitrogen exhaust pipe is designed inside the fresh air duct, allowing heat exchange to occur within the fresh air duct during nitrogen exhaust, effectively reducing indoor energy loss, while ensuring that the temperature of the fresh air drawn in is not too low to achieve an anti-condensation effect.

[0105] This solution addresses several key issues: the need for multiple pipe wrappings and additional drilling required for running both fresh air and nitrogen exhaust pipes simultaneously; the issue of excessive noise in the air compressor sample room; the need to add an extra filter to the end of the oxygen generator's intake pipe; the need to add an oxygen delivery pipe to deliver oxygen to the air conditioning unit; the issue of fresh air affecting indoor temperature due to large indoor-outdoor temperature differences; the issue of condensation appearing on fresh air ducts when introducing fresh air due to large indoor temperature differences; and the issue of monomolecules accumulating on the surface of oxygen-enriched membranes.

[0106] The oxygen generator provided in this application can purify oxygen from the air without an air compressor. By designing the fresh air component as a dual-duct system and the ductwork as a dual-channel system, it combines fresh air and oxygen generation functions, saving space and simplifying installation. It avoids the complex pipe management, wrapping, and hole enlargement required for wall penetration with multiple pipes. The oxygen generation system shares a filter with the fresh air unit, reducing consumable usage. Furthermore, by designing the oxygen generation system below the air conditioner panel, it eliminates the need for additional oxygen delivery pipes, allowing oxygen to be blown into the air conditioner and then distributed to the room by the indoor unit, thus improving oxygen generation efficiency.

[0107] The air conditioner of this application includes an oxygen generating device 300, an indoor unit 100, and a fresh air unit 200. The oxygen generating device consists of a piston system and an oxygen purification system. The oxygen generating device 300 is designed under the indoor unit panel, with the oxygen outlet facing inwards. The fresh air unit 200 is designed with dual air ducts, namely a fresh air duct 230 and a nitrogen exhaust duct 240. The air duct is designed as a dual-channel air duct, that is, a nitrogen exhaust duct 400 is designed inside the fresh air duct 220 to provide a nitrogen exhaust path. The ratio of the inner diameter D of the fresh air duct 220 to the outer diameter D1 of the nitrogen exhaust duct 400 is greater than or equal to 2, that is, D / D1≥2 satisfies the nitrogen exhaust requirement while ensuring the fresh air volume. Figure 13 );

[0108] This application designs the oxygen inlet to be inside the fresh air outlet 210, sharing a filter with the fresh air unit to reduce consumable usage. It also reduces the oxygen inlet pipeline path, improving oxygen production efficiency. The oxygen generator 300 comprises two chambers, a piston, and a drive motor. Each large chamber has a pure oxygen chamber and an air chamber located on either side of the piston. Each chamber has an inlet and an outlet, both equipped with one-way valves. The oxygen purification system consists of a hollow oxygen-enriched membrane placed within the chamber with inlets and outlets. The oxygen purification system has an inlet connected to the inner cavity of the oxygen-enriched membrane, while the outer cavity also has inlets and outlets. An N-connector (N≥3) is provided at the inlet of the oxygen purification system to connect to the inlet of the pure oxygen chamber in the multiple piston system.

[0109] The oxygen generation system is installed below the air conditioner panel with the oxygen outlet facing the inside of the air conditioner. The air inlet of the oxygen generation equipment extends to the air outlet of the fresh air component of the air conditioner to ensure that the oxygen generation system draws in clean air. The nitrogen exhaust outlet is connected to the nitrogen exhaust channel of the fresh air component to exhaust nitrogen outdoors.

[0110] The inlet of the oxygen purification system is connected to the intake port of the pure oxygen chamber in the piston system, and the piston movement provides negative pressure to purify oxygen.

[0111] The air inlet of the air chamber (i.e., the air inlet of the oxygen generator) extends to the fresh air outlet to draw in fresh, clean air for the oxygen generation system.

[0112] The air outlet of the air chamber is connected to the outer cavity of the purification system, providing clean air to the purification system. At the same time, the air flow carries away nitrogen molecules that are blocked on the outer surface of the oxygen-enriched membrane during oxygen purification, ensuring that oxygen molecules can pass through the oxygen-enriched membrane unimpeded to achieve the purpose of oxygen purification.

[0113] The purification system (i.e., the outlet of the oxygen generation system) faces the inside of the air conditioner. The purified oxygen is blown into the air conditioner, and the air conditioner's fan blows the oxygen into the indoor space to achieve the purpose of increasing room oxygen.

[0114] Implementation

[0115] like Figure 1 As shown, when the first moving part 321 moves to the left, oxygen in the first oxygen channel 323 of the second chamber 320 is discharged, and the first air channel 322 completes the intake action. Air from the second air channel 362 in the third chamber 360 is discharged to the first chamber 310 to provide raw material (air) for oxygen production. At the same time, the airflow carries away nitrogen molecules from the surface of the oxygen-enriched membrane, achieving the purpose of nitrogen removal. The second oxygen channel 363 in the third chamber 360 begins to absorb oxygen. When the piston moves to the right, oxygen in the second oxygen channel 363 of the third chamber 360 is discharged, and the second air channel 362 completes the intake action. Air from the first air channel 322 in the second chamber 320 is discharged to the first chamber 310 to provide raw material (air) for oxygen production. At the same time, the airflow carries away nitrogen molecules from the surface of the oxygen-enriched membrane, achieving the purpose of nitrogen removal. The purification chamber in the second chamber 320 begins to absorb oxygen. This cycle repeats to achieve a continuous oxygen production effect.

[0116] Control method

[0117] When the air conditioner is turned on, the sensors on it begin to collect information about the outdoor temperature and air quality.

[0118] When the outdoor temperature H: 0°C ≥ H or H ≥ 30°C; or when the outdoor PM2.5 level is higher than the program's set value, the fresh air unit operates at low speed to maintain positive pressure within the unit, providing clean air to the oxygen generator. The oxygen generator operates at high speed to ensure the indoor oxygen concentration. This prevents the low (high) temperature outdoor air from having a significant impact on indoor air quality, or reduces the premature wear and tear on the filter caused by poor outdoor air quality.

[0119] When the outdoor temperature H: 0 degrees < H or H < 30 degrees; or when the outdoor PM2.5 is less than the program set value, the fresh air fan runs at high speed and the oxygen generator runs at low speed to improve the efficiency of indoor air quality, ensure stable indoor oxygen concentration, and reduce wear and tear on the oxygen generator.

[0120] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0121] The oxygen generator mainly consists of a first chamber 310 and a second chamber 320. The first chamber 310 houses an oxygen purification component 311 for separating oxygen from the air. The second chamber 320 contains a first movable component 321, which moves along the inner wall of the chamber, thus forming two independent areas within the second chamber—a first air passage 322 and a first oxygen passage 323. Fresh air enters the first air passage 322 of the second chamber 320 through the fresh air outlet 210. Subsequently, through the movement of the first movable component 321, the air is guided to the air inlet 312 of the first chamber 310. Upon entering the first chamber 310, the air contacts the oxygen purification component 311, and oxygen is separated. The separated oxygen flows through the first oxygen outlet 313 of the first chamber 310. When the first movable component 321 moves in the opposite direction, the oxygen is introduced into the first oxygen passage 323 of the second chamber 320, and then, through communication with the indoor air, the oxygen is directly discharged into the indoor space, achieving immediate oxygen supply.

[0122] This application eliminates the need for an additional air compressor. By utilizing the piston effect of the first moving part 321, the noise level during equipment operation is greatly reduced. The oxygen purification component 311 acts directly on fresh air, thereby improving the efficiency of oxygen purification.
