Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an oxygen generating component and an air conditioner. Background Technology

[0002] Currently, as people pay increasing attention to indoor air quality, air conditioners are gradually integrating additional functions such as air purification, oxygen generation, and ventilation in addition to temperature regulation. Among them, the oxygen generation function is mainly achieved through separation technologies such as oxygen-enriched membranes, which separate oxygen from the air and deliver it indoors, while exhausting the remaining gas outdoors, thereby increasing the indoor oxygen concentration and improving human comfort. The ventilation function is usually achieved by an independent fresh air system, which uses dedicated fans and ducts to exhaust polluted indoor air to the outside while allowing fresh outdoor air to enter the room.

[0003] However, in existing technologies, the structures for oxygen generation and ventilation functions are independent of each other, and multiple installation spaces need to be reserved inside the air conditioner unit. This results in a complex and bulky overall structure, increases production costs, and reduces the space utilization rate of the product. In particular, in space-constrained models such as wall-mounted split air conditioners, it is difficult to achieve efficient integration of the two functions. Summary of the Invention

[0004] This invention provides an oxygen generating component and an air conditioner to solve the problem that existing oxygen generating components cannot simultaneously meet the needs of oxygen generation and ventilation in space-constrained structures.

[0005] To address the above problems, according to one aspect of the present invention, an oxygen generating component is provided, comprising:

[0006] The outer shell structure has an exhaust port, an oxygen inlet, and an openable and closable ventilation inlet at different locations. The exhaust port is connected to the outside, while the oxygen inlet and ventilation inlet are connected to the interior.

[0007] An oxygen-enriched membrane structure is set inside the cavity of the outer shell structure, with one side of the oxygen-enriched membrane structure facing the oxygen inlet.

[0008] The fan blades are rotated and housed within the cavity of the outer shell structure, and are located on the side of the oxygen-enriched membrane structure opposite to the oxygen inlet.

[0009] The oxygen generating unit has an oxygen generating mode and a ventilation mode. In the oxygen generating mode, the ventilation inlet is closed, the oxygen-enriched membrane structure is in operation, and the fan blades draw in air from the oxygen generating inlet. The drawn-in air passes through the oxygen-enriched membrane structure to separate oxygen and nitrogen. The separated nitrogen is output to the outside through the exhaust port, and the separated oxygen is delivered to the room. In the ventilation mode, the ventilation inlet is open, the oxygen-enriched membrane structure stops operating, and the fan blades draw in air from at least the ventilation inlet. The drawn-in air is output to the outside through the exhaust port.

[0010] Furthermore, the oxygen generating component also includes a damper, which is used to open and close the air exchange inlet. The damper may be a rotating structure, a sliding structure, or a roller shutter structure.

[0011] Furthermore, the outer shell structure includes a first outer shell, a second outer shell, and a volute connected in sequence. The oxygen inlet is located in the first outer shell, and the air exchange inlet is located in the second outer shell. The oxygen-enriched membrane structure is located in the first cavity formed by the first outer shell and the second outer shell. The fan blade is located in the second cavity formed by the second outer shell and the volute. The second outer shell has an air intake facing the other side of the oxygen-enriched membrane structure. The first cavity is connected to the second cavity through the air intake.

[0012] Furthermore, there is an air exchange channel between the oxygen-enriched membrane structure and the second shell, and the air exchange inlet is connected to the air intake through the air exchange channel.

[0013] Furthermore, a portion of the second outer shell and a portion of the volute form an exhaust channel, which is connected to the second cavity, and the outlet of the exhaust channel forms an exhaust port.

[0014] Furthermore, the oxygen generating component also includes a damper and a drive motor. Both the damper and the drive motor are mounted on the second housing. The drive motor drives the damper to swing, and the damper is used to control the opening and closing of the air exchange inlet.

[0015] Furthermore, the oxygen inlet has multiple supporting ribs, all of which are connected to the inner wall of the oxygen inlet; the oxygen generating component also includes a filter screen, which is disposed in the first cavity and located between the oxygen inlet and the oxygen-enriched membrane structure.

[0016] Furthermore, the oxygen-enriched membrane structure has an oxygen outlet connected to a vacuum pump, which is used to deliver oxygen that has passed through the oxygen-enriched membrane structure to the room; the oxygen-enriched membrane structure can be plugged into the cavity of the outer shell structure, which has an operating port for plugging and unplugging the oxygen-enriched membrane structure.

[0017] Furthermore, the outer shell structure has a top surface, a bottom surface, a first large side surface, a second large side surface, a first small side surface, and a second small side surface. The first large side surface and the second large side surface are arranged opposite to each other, and the first small side surface and the second small side surface are arranged opposite to each other. Among them, the oxygen inlet is located on the first large side surface, the air exchange inlet is located on the top surface, the exhaust port and the oxygen outlet are located on the bottom surface, and the operation port is located on the first small side surface.

[0018] According to another aspect of the present invention, an air conditioner is provided, the air conditioner including a bottom shell, a panel body and the aforementioned oxygen generating component, the oxygen generating component being installed at one end of the bottom shell, the panel body being connected to the bottom shell, and the panel body covering the oxygen generating component.

[0019] Furthermore, the ventilation inlet of the oxygen generating component is located on the top surface of the outer shell structure of the oxygen generating component, and the top surface of the panel has an air inlet corresponding to the ventilation inlet; there is an air flow gap between the panel and the oxygen generating component, and the oxygen generating component draws air from the air inlet at least when in oxygen generating mode or ventilation mode.

[0020] Furthermore, a dustproof grille is installed at the air inlet, and the oxygen generation component also includes an air damper. The air damper is used to open and close the air exchange inlet. The air damper has a rotating structure, and when the air damper is open, the highest point of the air damper is lower than the dustproof grille.

[0021] Furthermore, the oxygen generating component also includes a filter screen, which is pluggably installed between the oxygen inlet and the oxygen-enriched membrane structure. The outer shell structure has an operating port for plugging and unplugging the filter screen. The front of the panel has an inspection port and an inspection door, with the inspection port facing the operating port and the inspection door being detachably installed on the inspection port.

[0022] Furthermore, the air conditioner also includes a connector and an exhaust pipe. One end of the exhaust pipe is connected to the exhaust port of the oxygen generating component through the connector, and the other end of the exhaust pipe is connected to the outside.

[0023] In this design, the outer casing provides installation space for the oxygen-enriched membrane structure and the fan blades. Ventilation inlets, oxygen-generating inlets, and exhaust outlets are located at different positions on the casing, enabling the oxygen-generating component to simultaneously perform oxygen generation and ventilation functions. The oxygen-enriched membrane structure is used for air filtration and oxygen enrichment, while the fan blades provide power for gas flow, improving oxygen generation and ventilation efficiency. The opening and closing of the ventilation inlets allows for flexible switching between oxygen generation and ventilation functions. The gas inflow inlets are flexibly controlled according to functional requirements, guiding the gas through different flow paths within the oxygen-generating component. This avoids the structural complexity and large space requirements of traditional solutions that require separate oxygen generation and ventilation modules. This design optimizes the internal gas flow path without increasing the device's volume, balancing the dual needs of oxygen generation and ventilation, improving space utilization and overall device integration. It integrates oxygen generation and ventilation functions within a space-constrained air conditioner, avoiding the increased structural complexity of separate oxygen generation and ventilation structures and reducing the air conditioner's energy consumption.

[0048] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0049] like Figures 1 to 7 As shown, an embodiment of the present invention provides an oxygen generating component, comprising:

[0050] The outer shell structure 10 has an exhaust port 83, an oxygen inlet 111 and an openable and closable ventilation inlet 121 at different positions. The exhaust port 83 is connected to the outside, and the oxygen inlet 111 and the ventilation inlet 121 are both connected to the inside.

[0051] An oxygen-enriched membrane structure 20 is disposed within the cavity of the outer shell structure 10, with one side of the oxygen-enriched membrane structure 20 facing the oxygen inlet 111.

[0052] The fan blade 30 is rotatably disposed in the cavity of the outer shell structure 10 and is located on the side of the oxygen-enriched membrane structure 20 away from the oxygen-generating inlet 111.

[0053] The oxygen generating component has an oxygen generating mode and a ventilation mode. In the oxygen generating mode, the ventilation inlet 121 is closed, the oxygen-enriched membrane structure 20 is in operation, and the fan blade 30 draws air in from the oxygen generating inlet 111. The drawn-in air passes through the oxygen-enriched membrane structure 20 to separate oxygen and nitrogen. The separated nitrogen is output to the outside through the exhaust port 83, and the separated oxygen is delivered to the room. In the ventilation mode, the ventilation inlet 121 is open, the oxygen-enriched membrane structure 20 stops operating, and the fan blade 30 draws air in from at least the ventilation inlet 121. The drawn-in air is output to the outside through the exhaust port 83.

[0054] In this design, the outer shell structure 10 provides installation space for the oxygen-enriched membrane structure 20 and the fan blade 30. At the same time, ventilation inlet 121, oxygen production inlet 111 and exhaust port 83 are opened at different positions on the outer shell structure 10, so that the oxygen production component can simultaneously perform oxygen production and ventilation functions. The oxygen-enriched membrane structure 20 is used to achieve air filtration and oxygen enrichment, and the fan blade 30 is used to provide power for gas flow, promoting oxygen production and ventilation efficiency. The oxygen production function and ventilation function can be flexibly switched by opening and closing the ventilation inlet 121. The gas inlet can be flexibly controlled according to functional requirements, allowing it to enter different flow paths within the oxygen generation component. This avoids the structural complexity and large space occupation caused by the need for separate oxygen generation and ventilation modules in traditional solutions. The design of this application optimizes the internal gas flow path without increasing the device volume, taking into account both oxygen generation and ventilation needs, improving space utilization and overall device integration. It realizes the integration of oxygen generation and ventilation functions in a space-constrained air conditioner, avoiding the increased structural complexity caused by separate oxygen generation and ventilation structures, and reducing the energy consumption of the air conditioner.

[0055] Specifically, in ventilation mode, the oxygen-enriched membrane structure 20 stops operating, and the fan blades 30 can draw air from the ventilation inlet 121, or from both the ventilation inlet 121 and the oxygen-generating inlet 111. When the fan blades 30 draw air from both the ventilation inlet 121 and the oxygen-generating inlet 111, the oxygen-enriched membrane structure 20 remains in a stopped state, and the gas entering from the oxygen-generating inlet 111 does not undergo a filtration and enrichment process. This configuration increases the airflow in ventilation mode and improves ventilation efficiency.

[0056] like Figure 1 , Figure 2 As shown, the oxygen generating component also includes a damper 40, which is used to open and close the ventilation inlet 121. The damper 40 is a rotating structure, or a sliding structure, or a roller shutter structure.

[0057] In this embodiment, the damper 40 is located at the air exchange inlet 121 to achieve physical opening and closing control of the air exchange inlet 121. In the oxygen generation mode, the damper 40 closes the air exchange inlet 121, ensuring that the incoming air completely passes through the oxygen-enriched membrane structure 20, ensuring the filtration and enrichment effect, and improving the stability and independence of the switching process between the oxygen generation and air exchange modes.

[0058] The damper 40 can be selected as a rotating, sliding, or roller shutter type, ensuring the flexibility and reliability of the opening and closing control of the ventilation inlet 121. It can also be adapted to actual processing needs, improving the smoothness and stability of the damper 40's movement. The sliding or roller shutter type structure reduces the space occupied by the damper 40 when open, shrinking the overall size of the device and improving the integration and space utilization of the oxygen-generating component.

[0059] like Figure 1 As shown, the outer shell structure 10 includes a first outer shell 11, a second outer shell 12, and a volute 13 connected in sequence. The oxygen inlet 111 is located in the first outer shell 11, and the air exchange inlet 121 is located in the second outer shell 12. The oxygen-enriched membrane structure 20 is located in the first cavity formed by the first outer shell 11 and the second outer shell 12. The fan blade 30 is located in the second cavity formed by the second outer shell 12 and the volute 13. The second outer shell 12 has an air intake 122 facing the other side of the oxygen-enriched membrane structure 20. The first cavity is connected to the second cavity through the air intake 122.

[0060] In this embodiment, the first cavity provides installation space for the oxygen-enriched membrane structure 20, and the second cavity provides installation space for the fan blade 30, ensuring the stable operation of the oxygen-enriched membrane structure 20 and the fan blade 30 and preventing the external environment from damaging their structural integrity; the air inlet 122 faces the other side of the oxygen-enriched membrane structure 20, and the first cavity is connected to the second cavity through the air inlet 122, which facilitates the entry of gas from the first cavity into the second cavity and realizes airflow communication.

[0061] In oxygen generation mode, the air exchange inlet 121 is closed, the fan blade 30 operates to create negative pressure, causing indoor air to enter the first chamber through the oxygen generation inlet 111. After passing through the oxygen enrichment membrane structure 20 to complete oxygen enrichment, the remaining nitrogen and other gases enter the second chamber through the air intake 122 and are discharged outdoors through the exhaust port 83.

[0062] In ventilation mode, ventilation inlet 121 is opened and fan blade 30 starts running. Indoor air enters the second outer shell 12 through ventilation inlet 121 and flows into the second cavity through air intake 122. Then the gas is discharged outdoors through exhaust port 83. At this time, the amount of indoor gas is reduced. Opening indoor doors and windows promotes the entry of outdoor air, thereby realizing the circulation and circulation of indoor and outdoor air.

[0063] Optionally, the second housing 12 and the volute 13 are connected by snap-fit ​​or by fasteners, which ensures the stability and reliability of the connection between the second housing 12 and the volute 13, while simplifying the disassembly and assembly of the second housing 12 and the volute 13, making it easier to inspect and maintain the fan blades 30 inside, and improving the convenience of maintenance.

[0064] like Figure 3 As shown, there is an air exchange channel 81 between the oxygen-enriched membrane structure 20 and the second outer shell 12, and the air exchange inlet 121 is connected to the air intake 122 through the air exchange channel 81.

[0065] In this embodiment, an air exchange channel 81 is provided between the oxygen-enriched membrane structure 20 and the second outer shell 12, which facilitates the gas to enter the oxygen-generating component from the air exchange inlet 121 and flow to the second outer shell 12, thereby realizing the connection between the air exchange inlet 121 and the air intake 122 and ensuring the stable and smooth flow of gas.

[0066] like Figure 3 , Figure 5 As shown, a portion of the structure of the second outer shell 12 and a portion of the structure of the volute 13 form an exhaust channel 82, which is connected to the second cavity, and the outlet of the exhaust channel 82 forms an exhaust port 83.

[0067] In this embodiment, a portion of the structure of the second outer shell 12 and a portion of the structure of the volute 13 form an exhaust channel 82, and the outlet of the exhaust channel 82 forms an exhaust port 83. This enables the gas located in the second cavity to flow directionally along the exhaust channel 82 to the exhaust port 83, facilitating the timely discharge of the airflow from the oxygen generating component. This avoids the eddies and local flow accumulation caused by the ambiguous airflow path in the traditional structure, thereby improving exhaust efficiency.

[0068] In some embodiments, the oxygen generating component further includes a damper 40 and a drive motor. Both the damper 40 and the drive motor are mounted on the second housing 12. The drive motor drives the damper 40 to swing, and the damper 40 is used to control the opening and closing of the ventilation inlet 121.

[0069] In this embodiment, the drive motor provides power for the movement of the damper 40, enabling the damper 40 to precisely control the opening and closing of the air exchange inlet 121.

[0070] The damper 40 and the drive motor are mounted on the second housing 12, which improves the reliability and response speed of oxygen production and ventilation mode switching, avoids the problems of structural complexity and large space occupation caused by external control mechanisms, and realizes efficient integration and stable switching of oxygen production and ventilation functions.

[0071] like Figure 1 , Figure 2 and Figure 4 As shown, the oxygen inlet 111 has multiple support ribs 112, all of which are connected to the inner wall of the oxygen inlet 111; the oxygen generating component also includes a filter screen 50, which is disposed in the first cavity and located between the oxygen inlet 111 and the oxygen-enriched membrane structure 20.

[0072] In this embodiment, multiple support ribs 112 are provided inside the oxygen inlet 111, and all the support ribs 112 are connected to the inner wall of the oxygen inlet 111, which provides support for the first outer shell 11. At the same time, the airflow entering the oxygen generating component is initially diverted, avoiding local eddies or turbulence in the airflow at the inlet, and improving the stability of the airflow entering the first cavity.

[0073] Meanwhile, the filter screen 50 is installed in the first cavity and located between the oxygen inlet 111 and the oxygen-enriched membrane structure 20. It can intercept particulate matter, dust and impurities carried in the air, preventing them from flowing with the gas to the surface of the oxygen-enriched membrane structure 20 and causing damage to the structure of the oxygen-enriched membrane structure 20. This reduces the risk of membrane blockage and mechanical damage to the oxygen-enriched membrane structure 20 and ensures the long-term stable operation of the oxygen-enriched membrane structure 20.

[0074] like Figure 1 As shown, the oxygen-enriched membrane structure 20 has an oxygen outlet 21, which is connected to a vacuum pump. The oxygen outlet 21 is used to deliver oxygen that has passed through the oxygen-enriched membrane structure 20 to the room. The oxygen-enriched membrane structure 20 is pluggably placed in the cavity of the outer shell structure 10. The outer shell structure 10 has an operation port for plugging and unplugging the oxygen-enriched membrane structure 20.

[0075] In this embodiment, the oxygen-enriched membrane structure 20 is provided with an oxygen outlet 21. The suction action of the vacuum pump creates a pressure difference on both sides of the oxygen-enriched membrane structure 20, which causes oxygen in the air to pass through the membrane of the oxygen-enriched membrane structure 20 and be transported to the room, thereby improving the oxygen production efficiency.

[0076] Meanwhile, the oxygen-enriched membrane structure 20 is pluggably installed in the cavity of the outer shell structure 10. After long-term use, the user can easily remove the aged or clogged oxygen-enriched membrane structure 20 through the operation port without disassembling the whole machine, and replace or clean it. This avoids the problem of decreased oxygen production efficiency and increased airflow resistance caused by the performance degradation of the oxygen-enriched membrane structure 20, reduces maintenance difficulty, and extends the service life of the equipment.

[0077] In some embodiments, the outer shell structure 10 has a top surface, a bottom surface, a first large side surface, a second large side surface, a first small side surface, and a second small side surface, with the first large side surface and the second large side surface being arranged opposite to each other, and the first small side surface and the second small side surface being arranged opposite to each other; wherein, the oxygen inlet 111 is located on the first large side surface, the air exchange inlet 121 is located on the top surface, the exhaust port 83 and the oxygen outlet 21 are located on the bottom surface, and the operation port is located on the first small side surface.

[0078] In this embodiment, the outer shell structure 10 is provided with a top surface, a bottom surface, a first large side surface, a second large side surface, a first small side surface, and a second small side surface. The first large side surface and the second large side surface are arranged opposite to each other, and the first small side surface and the second small side surface are arranged opposite to each other. This forms a compact and well-defined structural layout, which improves the integration and space utilization of the overall structure, and enhances the ease of use of the oxygen generating component.

[0079] The oxygen inlet 111 is located on the first large side, allowing indoor air to directly enter the oxygen generating component in a direction perpendicular to the first large side, thus improving airflow efficiency; the ventilation inlet 121 is located on the top surface, forming a relatively independent spatial layout with the oxygen generating inlet 111, ensuring the efficient operation of the oxygen generating component in both oxygen generating and ventilation modes.

[0080] Both the exhaust port 83 and the oxygen outlet 21 are located on the bottom surface, which simplifies the installation of the whole machine. The operation port is located on the first small side, which allows maintenance personnel to directly pull out or insert the filter screen 50 for maintenance and replacement, reducing the difficulty of maintenance.

[0081] like Figure 6 , Figure 7 As shown, an embodiment of the present invention also provides an air conditioner, which includes a bottom shell 61, a panel body 62 and the aforementioned oxygen generating component. The oxygen generating component is installed at one end of the bottom shell 61, and the panel body 62 is connected to the bottom shell 61, with the panel body 62 covering the oxygen generating component.

[0082] In this embodiment, the oxygen generating component is installed at one end of the bottom shell 61, and the panel 62 is connected to the bottom shell 61 and covers the outside of the oxygen generating component, ensuring that the oxygen generating component and other structures are not affected by the external environment and guaranteeing the integrity of the structure and function. At the same time, the setting of the oxygen generating component enables the air conditioner to integrate the oxygen generation function and the ventilation function without increasing the overall size of the unit, thereby improving the performance of the air conditioner.

[0083] like Figure 6 As shown, the ventilation inlet 121 of the oxygen generating component is located on the top surface of the outer shell structure 10 of the oxygen generating component, and the top surface of the panel body 62 has an air inlet 621, which corresponds to the ventilation inlet 121; there is an air flow gap between the panel body 62 and the oxygen generating component, and the oxygen generating component draws air from the air inlet 621 at least when it is in oxygen generating mode or ventilation mode.

[0084] In this embodiment, there is an air flow gap between the panel 62 and the oxygen generating component, which allows indoor air to enter uniformly from the air inlet 621, and then selectively enter the oxygen generating component from the ventilation inlet 121 or the oxygen generating inlet 111 according to the mode requirements. This avoids the problems of increased airflow resistance and decreased suction efficiency caused by the complex air intake path in the traditional structure, and improves the overall reliability and efficiency of operation.

[0085] In some embodiments, a dustproof grille is provided at the air inlet 621, and the oxygen generating component also includes a damper 40. The damper 40 is used to open and close the air exchange inlet 121. The damper 40 has a rotating structure, and when the damper 40 is open, the highest point of the damper 40 is lower than the dustproof grille.

[0086] In this embodiment, a dustproof grille is provided at the air inlet 621, which can effectively block external dust from entering the oxygen generating component with the airflow, avoid dust deposition on the surface of the oxygen-enriched membrane structure 20 or jamming of the rotating mechanism of the damper 40, and ensure the normal operation of the oxygen generating and ventilation functions of the air conditioner.

[0087] Meanwhile, when the damper 40 adopts a rotating structure and is located at the air exchange inlet 121 of the oxygen generating component, the highest point of the damper 40 in the open state is lower than the dustproof grille, ensuring that the damper 40 always maintains a safe gap with the dustproof grille during rotation, avoiding mechanical interference or scratching, and ensuring the smooth opening and closing of the damper 40.

[0088] like Figure 6 As shown, the oxygen generating component also includes a filter screen 50, which is pluggably installed between the oxygen inlet 111 and the oxygen enrichment membrane structure 20. The outer shell structure 10 has an operation port for plugging and unplugging the filter screen 50. The front of the panel body 62 has an inspection port 622 and an inspection door 623. The inspection port 622 is directly opposite the operation port, and the inspection door 623 is detachably installed on the inspection port 622.

[0089] In this embodiment, the filter screen 50 is pluggably installed between the oxygen inlet 111 and the oxygen-enriched membrane structure 20 to perform preliminary filtration on the air entering the oxygen generating component, preventing impurities from directly contacting the oxygen-enriched membrane structure 20 and causing structural blockage or damage.

[0090] The outer casing 10 is provided with an operation port, which is aligned with the insertion and removal direction of the filter 50, so that the filter 50 can be directly inserted or removed without disassembling the entire unit. The front panel 62 is provided with an inspection port 622, which is directly opposite the operation port of the outer casing 10, so that the user can insert or remove the filter 50 from the outside of the panel 62.

[0091] The access door 623 is detachably installed on the access port 622. When the filter 50 needs to be replaced, the access door 623 can be removed, and the operation port on the oxygen generating unit can be directly operated through the access port 622. This allows for convenient insertion and removal of the filter 50 for maintenance, avoiding the cumbersome process of disassembling the entire machine in the traditional process, and improving the efficiency of filter 50 replacement and the user experience.

[0092] like Figure 6 , Figure 7 As shown, the air conditioner also includes a connector 71 and an exhaust pipe 72. One end of the exhaust pipe 72 is connected to the exhaust port 83 of the oxygen generating component through the connector 71, and the other end of the exhaust pipe 72 is connected to the outside.

[0093] In this embodiment, one end of the exhaust pipe 72 is connected to the exhaust port 83 of the oxygen generating component through the connector 71, and the other end of the exhaust pipe 72 is connected to the outside. This structure ensures that the nitrogen-rich waste gas generated during the oxygen generation process and the indoor air discharged in the ventilation mode can be stably and directionally transported to the outside, improving the exhaust efficiency and the overall airtightness of the system. At the same time, due to the connecting function of the connector 71, reliable assembly between the exhaust pipe 72 and the exhaust port 83 of the oxygen generating component is realized, enhancing the stability and durability of the structure.

[0094] The specific process of the technical solution in this application is as follows:

[0095] In oxygen generation mode, the damper 40 of the oxygen generation component in the air conditioner is closed to seal the ventilation inlet 121. The oxygen-enriched membrane structure 20 is in operation, and the fan blades 30 are activated. Indoor air enters through the air inlet 621 of the panel 62, passes through the air flow gap into the oxygen generation inlet 111, flows through the filter screen 50 located in the first cavity for preliminary filtration, and then enters the oxygen-enriched membrane structure 20. The oxygen-enriched membrane structure 20 allows oxygen to pass through the membrane and be delivered to the room through the oxygen outlet 21. Residual gases such as nitrogen enter the second cavity through the air intake 122 of the second outer shell 12, and then are discharged from the exhaust port 83 located on the bottom through the exhaust channel 82 formed by the second outer shell 12 and the volute 13. The exhaust is then delivered to the outside through the connector 71 and the exhaust pipe 72. At this time, the ventilation inlet 121 is closed by the damper 40, and the airflow only enters through the oxygen generation inlet 111, ensuring the relative independence of the oxygen generation mode path and guaranteeing the efficiency of air filtration and oxygen enrichment.

[0096] In ventilation mode, the damper 40 is driven by the motor to swing to the open position, the ventilation inlet 121 opens, the oxygen-enriched membrane structure 20 stops operating, the fan blades 30 start, and indoor air enters through the air inlet 621 of the panel 62, passes through the air flow gap into the ventilation inlet 121, is directionally guided to the air intake 122 through the ventilation channel 81, enters the second cavity, and is then discharged to the outside through the exhaust channel 82 and the exhaust port 83. At this time, the oxygen-enriched membrane structure 20 is in a stopped state, and the ventilation inlet 121 and the oxygen generation inlet 111 are spatially isolated. The airflow can completely bypass the first cavity without passing through the filter 50 and the oxygen-enriched membrane structure 20, reducing fluid resistance in ventilation mode and achieving efficient ventilation. As indoor air is continuously discharged, a negative pressure environment is formed indoors, and external air flows in naturally through doors and windows to replenish it, thereby achieving air circulation.

[0097] During maintenance, users can open the inspection port 622 by removing the inspection door 623 on the front of the panel 62, and then directly insert or remove the filter screen 50 for maintenance and replacement by aligning the inspection port 622 with the operation port of the outer shell structure 10, without having to disassemble the entire machine structure. This improves the convenience of replacing the filter screen 50 and reduces the difficulty of equipment maintenance.

[0099] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification.

[0100] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0101] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as exemplary only and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0102] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0103] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0104] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
