[0003] Conventional environmental control equipment, such as air conditioners, air purifiers, humidifiers, and oxygen concentrators, is typically purchased and installed as individual units. These devices are single-function, require multiple placement locations and power outlets, leading to cluttered indoor spaces and a lack of interoperability. More importantly, most of these devices employ an integrated design; a malfunction in any module or the need to replace consumables can necessitate complete disassembly and return to the factory, making maintenance difficult. Furthermore, during installation, the power supply lines, gas lines, and signal cables are often exposed on the walls, severely impacting the aesthetics of the room and making it difficult to coordinate with the interior design style.

[0014] Furthermore, in this invention, the oxygen module is 68±5cm above the ground; the fresh air module is 86±5cm above the ground.

[0015] A control system for the integrated environmental control system, comprising: Multiple environmental sensors are installed indoors to collect indoor environmental parameters in real time, including at least oxygen concentration, humidity, and temperature. The controller is electrically connected to the oxygen generation module and fresh air module of the outdoor unit, each functional module of the indoor unit, and the environmental sensor. The communication module is used to communicate with mobile terminals and cloud servers; The controller is configured to execute the following control strategy: Oxygen concentration graded control strategy: When the indoor oxygen concentration is lower than the first preset threshold, the oxygen generation module and the fresh air module are activated simultaneously according to a preset ratio; when the indoor oxygen concentration is higher than the second preset threshold, the oxygen generation module is suspended; when the indoor oxygen concentration is between the first preset threshold and the second preset threshold, the normal oxygen supply mode is maintained. Temperature and humidity coordinated control strategy: When the indoor humidity is higher than the preset humidity threshold, the air conditioner dehumidification mode is activated in conjunction with the infrared control module.

[0016] Furthermore, in this invention, in the oxygen concentration graded control strategy, the first preset threshold is 22%, the second preset threshold is 25%, and the preset ratio is fresh air volume: oxygen production volume = 80:1; when the indoor oxygen concentration is below 22%, oxygen is supplied according to the preset ratio; when the indoor oxygen concentration is above 25%, the oxygen production module is automatically suspended; when the indoor oxygen concentration is between 21% and 24%, the normal mode is maintained. The temperature and humidity coordinated control strategy also includes: activating the humidification module when the indoor humidity is below 40%RH, and activating the air conditioning dehumidification mode through the infrared control module when the indoor humidity is above 60%RH, so as to maintain the indoor humidity between 40% and 60%RH.

[0017] This invention has at least the following advantages or beneficial effects: This invention's regulating system detachably stacks multiple functional modules vertically within the housing. These modules are electrically connected sequentially, and each module has a vertically running oxygen and fresh air channel. This allows for independent installation and quick plug-and-play of each module. When any module malfunctions or requires replacement of consumables, it can be easily removed from the stack for repair or replacement without disassembling the entire unit, significantly improving maintenance efficiency. Furthermore, the oxygen and fresh air pipes are routed sequentially through the vertical channels of each module, achieving centralized wiring and avoiding the tangled pipework of traditional equipment, thus simplifying the internal structure. The outdoor unit's oxygen generation and fresh air modules are connected to the indoor unit's oxygen and fresh air channels via oxygen and fresh air pipes, respectively. Oxygen and filtered fresh air are then output through outlets at the corresponding oxygen and fresh air modules, forming an indoor-outdoor air circulation system. This enables coordinated operation of oxygen generation and fresh air functions, effectively solving the problems of insufficient indoor oxygen content and poor air quality.

[0018] This invention's control system uses multiple environmental sensors to collect real-time indoor environmental parameters such as oxygen concentration, humidity, and temperature. The controller is electrically connected to the oxygen generation and fresh air modules of the outdoor unit, as well as various functional modules and environmental sensors of the indoor unit. This enables multi-dimensional real-time perception of the indoor environment, providing a reliable data foundation for precise control. The controller executes a graded oxygen concentration control strategy: when the indoor oxygen concentration is below a first preset threshold, the oxygen generation and fresh air modules are activated simultaneously according to a preset ratio; when it is above a second preset threshold, the oxygen generation module is paused; and when it is between the two, the normal oxygen supply mode is maintained. This introduces refined proportional control and a multi-mode switching mechanism, using a large proportion of fresh air to replace exhaust gas while precisely compensating for oxygen molecules with a small proportion of oxygen generation, achieving a dynamic balance between oxygen concentration and air quality, avoiding large fluctuations in oxygen concentration or energy waste caused by traditional simple on / off control. The controller also executes a coordinated temperature and humidity control strategy: when the indoor humidity is above a preset humidity threshold, the air conditioning dehumidification mode is activated via an infrared control module. This enables cross-functional linkage between environmental control equipment and air conditioning, automatically maintaining indoor humidity within a comfortable range without manual user operation, improving ease of use and intelligence.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example

[0024] Please refer to Figures 1-8 This embodiment provides an integrated environmental control system, including an indoor unit 100 and an outdoor unit 300. The indoor unit 100 is installed in an indoor corner and includes a housing 110 and multiple functional modules 200 disposed inside the housing 110. Air inlets 111 and air outlets 112 are provided on both sides of the housing 110 for indoor air circulation. A detachable panel 120 is provided on the front side of the housing 110 for easy disassembly and assembly, as well as for inspection and maintenance of the internal functional modules 200.

[0025] The casing 110 has a fan-shaped cross-section and is made of cold-rolled steel. It includes a base, a top sealing plate, a back plate, and two side plates. The back plate is L-shaped to fit the corner of the wall. Connecting brackets with screw holes 113 are provided on both sides of the back plate, allowing it to be fixed to the wall with expansion bolts. When local modifications are inconvenient, the main frame does not need to be fixed to the wall, and the machine can be moved. The two side plates are respectively snapped onto the back plate using a snap-fit / slot 510 or other structural method. The left side plate has an air inlet 111, and the right side plate has an air outlet 112. The fan-shaped cross-section of the casing 110 allows the equipment to be installed close to the corner of the wall, making full use of this usually unused space. The narrow ends of the fan shape create a natural transition with the wall panel, with no obvious visual protrusion, effectively reducing the space occupied in the room. The air inlet 111 and air outlet 112 are respectively located on the two side plates, making the air intake and exhaust direction lateral, avoiding the problem of front air intake and exhaust being blocked by the bed or furniture.

[0026] Panel 120 includes three independently detachable components from top to bottom: an upper panel 121, a middle panel 122, and a lower panel 123. These components are snapped together between the two side panels using a snap-fit / slot 510 or similar structural method. The upper panel 121 is approximately 50cm high, and the middle panel 122 is approximately 145cm high. Therefore, the indoor unit panel 120 has a visually harmonious proportion from bottom to top (50-145-50). This proportion is also aesthetically pleasing, facilitates injection molding, and keeps mold costs under control. Inside the housing 110, from top to bottom, are a functional module expansion area 130, a basic module area 140, and a water, electricity, and gas base area 150. The basic module area 140 is used to install multiple functional modules 200. The functional module expansion area 130 provides reserved space for expanding the functional modules 200. The water, electricity, and gas base area 150 is used to integrate power supply pipes 151, oxygen pipes 152, and fresh air pipes 153. Specifically, the back panel corresponding to the water, electricity, and gas base area 150 has a pipe integration port. The power supply pipe 151, oxygen pipe 152, and fresh air pipe 153 pass through the pipe integration port into the machine casing 110. All external pipelines enter the machine from the same area, facilitating installation and maintenance. The bottom panel 123 is mainly used for installing and connecting the water, electricity, and gas connectors of the whole machine, adding water to the water tank, and replacing the water bucket 157. The middle panel 122 is mainly used for plugging and unplugging internal modules and operating the digital tube display. The top panel 121 is a reserved module cover panel 120. In addition, the top panel 121 is equipped with a decorative machine working breathing light. LED lights are also installed on the side panels along their vertical direction, which can be used to adjust the indoor lighting.

[0027] The three-section detachable panel 120, corresponding to the three functional areas, allows for customization of the panel 120's color to match the interior wall design, enhancing aesthetics. Furthermore, for malfunctioning internal modules, the corresponding panel 120 can be individually removed and installed, enabling precise maintenance. When the water, electricity, and gas base area 150 needs pipe connection or malfunctions, simply remove the lower panel 123 for operation. When the functional modules 200 in the basic module area 140 require repair or consumable replacement, simply remove the middle panel 122 for module insertion / removal. When users require functional upgrades, simply remove the upper panel 121 and utilize the physical space of the functional module expansion area 130 to add new functional modules 200 or stack identical functional modules 200 to enhance functionality. This partitioned design makes maintenance operations more precise and efficient, eliminating the need to disassemble the entire unit.

[0028] Furthermore, the water, electricity, and gas base area 150 corresponding to the lower panel 123 is mainly divided into two spaces, separated into upper and lower layers by a partition 156, with a total height of approximately 50cm. A humidification module is also installed within the water, electricity, and gas base area 150, comprising an atomizing water tank 154. The atomizing water tank 154 is mounted on the partition 156, with a humidifying atomizing port on its top for discharging atomized gas through the air outlet 112. The atomizing water tank 154 is connected to an external water purifier via a water pipe, and also to a replaceable water tank 157 independently placed below the partition 156, enabling both automatic water replenishment and manual water replacement modes. The humidification module provides the system with humidity regulation capabilities. The atomizing water tank 154 utilizes ultrasonic atomization technology, atomizing water and then delivering it into the room via the air outlet 112. The water tank can be automatically replenished by connecting to a water purifier via a water pipe, or connected to the replaceable water tank 157, allowing users to choose the water supply method according to their actual usage conditions. The water, electricity, and gas base area 150 is located at the bottom of the unit, facilitating water changes. The humidification module can be connected to a wall socket via an independent circuit or to the power supply line 151, allowing for flexible power supply options.

[0029] Specifically, the atomizing water tank 154 should have a volume of 5L and a height of approximately 20cm. It is internally equipped with a water level sensor, a solenoid valve, and a water pump. The water level sensor detects the internal water level; when the level is too low, the water pump is activated to draw water from the water tank 157 or the water purifier into the water tank. The solenoid valve is located on the water pipe to control the water supply. After the humidification function depletes the water tank 157, the user can replace it with a new one or add purified water. Understandably, the water tank is designed with an irregular shape, avoiding internal water, gas, and electricity pipes, based on the main frame and the cross-sectional shape of the panel 120, to increase the effective volume of the water tank.

[0030] Furthermore, to prevent mold and bacterial growth on components such as the water tank and pipes, ultraviolet germicidal lamps are installed inside the casing 110 around the purified water tank 157 and the atomizing water tank 154. Simultaneously, to enable automatic water filling of the atomizing water tank 154, a baseboard can be added in conjunction with the modification, with a water supply hose embedded within the baseboard to introduce purified water from the water purifier and connect it to the atomizing water tank 154.

[0031] In this embodiment, multiple functional modules 200 are detachably stacked and installed inside the housing 110 in a vertical direction. Each module is about 18cm high. The functional modules 200 are electrically connected in sequence, and each functional module 200 is provided with an oxygen channel 410 and a fresh air channel 420 in a vertical direction.

[0032] By vertically and detachably stacking multiple functional modules 200 inside the housing 110, the physical separation and independent installation of each functional module 200 are achieved. Each functional module 200 has a vertically penetrating oxygen channel 410 and a fresh air channel 420, allowing oxygen and fresh air to pass sequentially through each module, avoiding the problem of tangled pipes found in traditional equipment. The oxygen generation module 310 and fresh air module 320 of the outdoor unit 300 are connected to the corresponding channels of the indoor unit 100 via oxygen pipe 152 and fresh air pipe 153, respectively. The oxygen module 220 outputs oxygen and discharges it indoors through the air outlet 112, while the fresh air module 230 discharges filtered fresh air through the air outlet 112, forming an indoor-outdoor air circulation system. When a functional module 200 malfunctions or requires consumable replacement, it can be repaired or replaced simply by removing it from the stacked structure, without disassembling the entire unit, greatly improving maintenance efficiency. Meanwhile, the modules are electrically connected in sequence, enabling unified management of power supply and signal transmission.

[0033] As an example, each functional module 200 includes a standard mounting unit 400 and a functional module 500 adapted to and plugged into the standard mounting unit 400. For example, the oxygen module 220 includes a standard mounting unit 400 and an oxygen module that is plugged into it. The standard mounting unit 400 is injection molded, and adjacent standard mounting units 400 are stacked vertically on top of each other. Each standard mounting unit 400 has a power strip and a power socket that can be plugged into each other at the top and bottom to realize the electrical connection between adjacent modules without additional wiring. The standard mounting unit 400 at the bottom is plugged into the power supply line 151 to realize the centralized introduction and step-by-step transmission of power. The power strips and power sockets of each standard mounting unit 400 are interconnected internally through wires or conductive sheets, and an electrical interface 433 is provided on the side facing the functional module 500. The electrical interface 433 realizes the electrical connection with the functional module 500. Furthermore, the standard installation unit 400 has a through hole 431 on the side facing the functional module 500, which is used to connect with the air passage of the functional module 500 or to the inside of the housing 110 to realize the exhaust of oxygen and fresh air.

[0034] Specifically, the standard mounting unit 400 has a triangular cross-section. One of its base sides (facing the functional module 500) has a space for accommodating the functional module 500, forming a mounting plane 430. Both its top and bottom surfaces are horizontal, facilitating stable stacking. The top surface of the standard mounting unit 400 is equipped with a female high-voltage socket 450 and a male low-voltage power strip 460, while the bottom surface correspondingly has a male high-voltage socket 470 and a female low-voltage power strip 480. Electrical connection is achieved simply by plugging them in during stacking. Multiple insertion posts 432 are located at the four corners of the mounting plane 430. The side of the functional module 500 facing the standard mounting unit 400 has multiple slots 510. The slots 510 and insertion posts 432 are fitted together with an interference fit, enabling stable connection and quick assembly / disassembly of the functional module 500. Users can replace modules without tools. A through hole 431 is provided at the center of the mounting surface 430. The through hole 431 is designed to connect with the oxygen channel 410 or the fresh air channel 420 at the corresponding module position to allow oxygen or fresh air to be discharged. For example, it connects with the oxygen channel 410 at the oxygen module 220 position. When oxygen is delivered to this position, it is discharged through the through hole 431 and quickly discharged into the room by the fan 441 of the air outlet 112. The through hole 431 connects with the fresh air channel 420 at the fresh air module 230 position. When fresh air is delivered to this position, it is discharged through the through hole 431, filtered by the fresh air module 230, and then discharged into the room by the fan 441. The mounting surface 430 is also provided with a high-voltage socket and a low-voltage socket, which are respectively connected to its internal high-voltage and low-voltage circuits. When the functional module 500 is plugged into the corresponding mounting surface 430, the electrical accessories on its back side can be connected to the corresponding socket.

[0035] It should be noted that since the oxygen module 220 only outputs oxygen, the power and low-voltage sockets on the mounting surface 430 at this module location do not require any electrical components to be plugged in or unplugged. Similarly, since the fresh air module 230 only filters and outputs fresh air, no electrical components need to be plugged in or unplugged at this module location. However, at the purification module location, the corresponding socket can be selected for plugging and unplugging.

[0036] Furthermore, the standard installation unit 400 is equipped with identification marks corresponding to the functional modules 500 (such as the word "O2" or an oxygen cylinder icon or numerical sequence corresponding to the oxygen module 220), which facilitates user identification of the functional type of each module, enables plug-in identification, avoids incorrect installation, and improves user experience. (See Figures 5 and 6). Figure 8 In this embodiment, each functional block is labeled in numerical order from bottom to top, and the labels are set on the plug-in post 432 and the corresponding functional module 500 to facilitate identification during installation.

[0037] As an example, the oxygen channel 410 and the fresh air channel 420 are independently located on the standard installation unit 400, and sealing rings 490 are embedded at the ends of the channels to ensure that the standard installation units 400 are sealed together after stacking, preventing gas leakage. The oxygen pipe 152 is detachably connected to the oxygen channel 410 of the bottom standard installation unit 400 and communicates with the through hole 431 of the corresponding standard installation unit 400 at the oxygen module 220 position to achieve oxygen output. The fresh air pipe 153 is detachably connected to the fresh air channel 420 of the bottom standard installation unit 400 and communicates with the fresh air module 230 at the fresh air module 230 position. After being filtered by the fresh air module 230, it is discharged from the air outlet 112. Specifically, the ends of the oxygen pipe 152 and the fresh air pipe 153 are provided with connectors. The connectors are connected to the bottom inlets of the oxygen channel 410 and the fresh air channel 420 by threading, snap-fitting, or plugging, and are sealed with sealing structures such as sealing rings. Figure 8 .

[0038] Furthermore, it also includes oxygen-sealing silicone plugs 411 and fresh air-sealing silicone plugs, which can be used to seal oxygen channels 410 and fresh air channels 420 as needed. For example, when there is no need to connect to the oxygen supply pipe pre-embedded within the top corner line 800, oxygen channel 410 can be sealed with silicone plugs. Figure 8 The principle of the fresh air duct 420 is the same. Under normal circumstances, silicone plugs are used for sealing. When it is necessary to pre-embed fresh air duct 153 within the top corner line 800 for diffused fresh air exhaust, the silicone plugs can be removed for connection.

[0039] As an example, the standard mounting unit 400 described above has fan slots 440 vertically arranged on both sides. Fans 441 are inserted vertically at intervals within the fan slots 440. A plug-in bracket is provided on one side of the fan 441 for plugging into the fan slot 440. The plug-in bracket has an interference fit with the fan slot 440, ensuring a stable connection. Alternatively, the fan 441 can be a wireless fan 441, directly communicating wirelessly with the controller of the power supply and display module. Alternatively, a corresponding electrical socket can be provided within the fan slot 440, with a compatible plug on the fan 441's connector, allowing for electrical connection after plugging. The fan 441 on the left, opposite the air inlet 111, is an exhaust fan 441 used to draw in fresh outdoor air or indoor return air. The fan 441 on the right, opposite the air outlet 112, is a ventilation fan 441 used to exhaust treated air into the room.

[0041] The power supply and control module 210 corresponds to the touch screen display on the middle panel 122, with a height of approximately 158cm from the ground. This height conforms to ergonomics, facilitating operation and observation. A power distribution system is designed based on module load and power factors, allowing modules to be powered on sequentially and illuminated one by one. This is used for overall power distribution and user interaction control, thereby improving the reliability of the entire system. The functional module 500 corresponding to the power supply and control module 210 includes a main control circuit board and a touch screen display driver circuit, electrically connected to the touch screen display on the middle panel 122. The oxygen module 220 outputs oxygen, with a height of 68cm from the ground, roughly the same as the height of a person lying down, facilitating effective oxygen diffusion to the surrounding area. The functional module 500 corresponding to the oxygen module 220 includes an oxygen concentration sensor, connected to the oxygen generation module 310 of the outdoor unit 300. The fresh air module 230 filters and outputs fresh air, with a height of 86cm from the ground, conforming to the breathing zone height of a person sitting or lying down, ensuring that fresh air effectively covers the breathing area. The functional modules 500 corresponding to the fresh air module 230 include a PM2.5 sensor, a TVOC sensor, and a high-efficiency filter (such as an activated carbon filter).

[0042] As an example, the purification module includes a negative ion generator sub-module 240, a plasma generator sub-module 250, and an aromatherapy sub-module 260. The negative ion generator sub-module 240 is used to release negative ions to purify the air, the plasma generator sub-module 250 is used to generate plasma to kill bacteria and viruses, and the aromatherapy sub-module 260 is used to atomize aromatherapy essential oils (such as lavender or sandalwood essential oils for sleep and relaxation) and discharge them through the air outlet 112. The essential oil container is 200ml or more and is set to intermittent spraying to extend the use time of the essential oils and reduce consumable expenses. Each sub-module also includes a standard installation unit 400 and a corresponding functional module 500.

[0043] The purification module integrates multiple purification methods. The negative ion generator sub-module 240 releases negative ions to improve air quality; the plasma generator sub-module 250 generates plasma through discharge to kill bacteria and viruses in the air; and the aromatherapy sub-module 260 uses ultrasonic atomization technology to atomize essential oils and discharge them with the airflow, creating a sleep-inducing atmosphere. All sub-modules use the same standard mounting unit 400 and functional module 500 structure, ensuring modular uniformity and interchangeability.

[0044] Further, the plurality of functional modules 200 further include a temperature and humidity regulation module and a light and sound module 280 electrically connected to the power supply display and control module 210; wherein the temperature and humidity regulation module includes an infrared control module 270, the infrared control module 270 is in infrared communication connection with an indoor air conditioner through an infrared emitting tube, the infrared control module 270 has a built-in infrared code library for air conditioners of multiple brands and has a self-learning function, and it is electrically connected to the humidification module and the indoor temperature and humidity sensor respectively through the power supply display and control module. The light and sound module 280 includes an integrated light control unit, a sound unit and a Bluetooth unit, which are used to control system light and music as well as indoor light and music, adjust indoor light and play sleep-aiding music.

[0045] The temperature and humidity regulation module establishes infrared communication connection with the indoor air conditioner through the infrared control module 270, so as to realize linkage control with the air conditioner. The infrared control module 270 is electrically connected to the humidification module and the temperature and humidity sensor through the power supply display and control module. When the temperature and humidity sensor detects that the humidity is too high, the controller sends a dehumidification instruction to the air conditioner through the infrared control module 270 to start the dehumidification mode of the air conditioner; when the humidity is too low, the controller directly starts the humidification module. The light and sound module 280 integrates light control, sound and Bluetooth functions, users can play sleep-aiding music via Bluetooth connection, and control the brightness, color temperature and color of the light, so as to create a comfortable sleep environment.

[0046] In this embodiment, an integrated electric / pneumatic quick connector 160 is provided at the top of the housing 110 (at the top sealing plate), such as Figure 3 and Figure 5 . The integrated electric / pneumatic quick connector 160 is integrated by an oxygen quick connector, a power supply quick connector, an audio data quick connector and the like, and is used for realizing quick connection with the oxygen supply pipe, power line and audio data line preset in the bedroom top corner line 800. A decorative outer shell 700 is arranged between the indoor unit 100 and the top corner line 800. The decorative outer shell 700 is also composed of a decorative side plate and a decorative panel 120, and is respectively connected (snap-fitted) with the side plate and the panel 120 of the housing 110 to form a continuous appearance surface. A containing space is formed between the decorative outer shell 700 and the wall surface, and the containing space is used for hiding pipelines, including the oxygen supply pipe, power line, audio data line in the top corner line 800, as well as the refrigerant pipe and drain pipe of the air conditioner, realizing complete hiding of the pipelines, so that the equipment perfectly fits with the indoor decoration hard furnishings. When it is necessary to inspect and repair the internal pipelines, the operation can be carried out only by disassembling the decorative outer shell 700, without damaging the wall surface or the top corner line 800. The material and color of the decorative outer shell 700 are consistent with those of the top corner line 800 / the skirting line, which cooperates to shield the refrigerant pipe of the indoor air conditioner unit, making the bedroom more beautiful and tidy.

[0047] The oxygen channel 410 connects to the oxygen quick-connect fitting of the integrated electric / gas quick-connect fitting 160 via an oxygen connecting pipe, allowing oxygen to be delivered to the diffused oxygen supply pipeline within the ceiling slab 800. The power and data connectors of the standard installation unit 400 at the top are electrically connected to the power quick-connect fitting via wires. The lighting and audio module 280 also extends an audio cable that connects to the audio data quick-connect fitting, transmitting power and audio signals to the audio and lighting equipment within the ceiling slab 800. The integrated electric / gas quick-connect fitting 160 enables rapid connection of the equipment to the pre-installed pipelines within the ceiling slab 800, achieving seamless integration of the equipment with the interior decoration.

[0048] In this embodiment, the outdoor unit 300 is installed outdoors and includes an oxygen generation module 310 and a fresh air module 320. The oxygen generation module 310 is connected to the oxygen channel 410 through an oxygen pipe 152 and outputs oxygen through the air outlet 112 at the oxygen module 220. The fresh air module 320 is connected to the fresh air channel 420 through a fresh air pipe 153 and outputs filtered fresh air through the air outlet 112 at the fresh air module 230.

[0049] Specifically, the materials and technical solutions for the outdoor unit casing and internal pipes, fans and other components must fully consider anti-aging, high temperature, waterproof and dustproof measures; the outdoor unit operating noise ≤55dB; the outdoor unit oxygen module 310 and fresh air module 320 adopt a horizontal layout with left and right parallel arrangement, which can be placed on the air conditioner outdoor unit.

[0050] The outdoor unit's fresh air module 320 connects to the indoor unit via a 75mm opening, using a unidirectional axial fan to introduce fresh outdoor air. It is equipped with a pre-filter (G1-G4 grade, coarse dust filtration ≥5um) and a high-efficiency filter (three-dimensional porous structure, small particle filtration efficiency ≥99.99%). Fresh air operation times: When the bedroom is unoccupied and outdoor air quality is good, it can be started on a timer (e.g., 9:00-11:00 AM) / operated by the indoor unit or tablet / remotely controlled via a mobile app. Outdoor unit sample module: Connected to the indoor unit via a 5-8mm flexible hose (sharing a wall hole with the fresh air duct 153); oxygen flow rate: ≥10L / min; oxygen concentration: (90±3)%; oxygen outlet pressure: 30-70kPa); can automatically adjust the oxygen concentration according to the indoor oxygen concentration (real-time monitoring range 19%-25%), and is equipped with necessary sensors to meet oxygen concentration monitoring; oxygen production working time: before and during sleep, timed start (e.g., 9 pm-11 pm) / indoor unit one-button mode (e.g., oxygen-enriched mode / health and wellness mode / energy-saving mode) or tablet / mobile phone APP.

[0051] Example 2 The present invention also provides a control system for the above-mentioned integrated environmental control system, the control system comprising multiple environmental sensors, a controller, an infrared control module and a communication module.

[0052] Multiple environmental sensors are installed in the bedroom, including temperature and humidity sensors, oxygen concentration sensors, PM2.5 sensors, TVOC sensors, and formaldehyde sensors. The temperature and humidity sensors are connected via I... 2 The C-bus is electrically connected to the controller, and the oxygen concentration sensor is electrically connected to the controller via a UART interface. The acquisition accuracy of each environmental sensor is ±1%, and the response time is ≤5 seconds.

[0053] The controller uses an ARM-based embedded processor and is electrically connected to the oxygen generation and fresh air modules of the outdoor unit, as well as the various functional modules and environmental sensors of the indoor unit. The controller has built-in Flash memory for storing control strategy parameters and operation logs.

[0054] The infrared control module and controller are electrically connected via a UART serial port. The infrared control module has a built-in infrared code library of mainstream air conditioner brands (Gree, Midea, Haier, Hisense, Daikin, etc.) and features a self-learning function. Upon first use, the user points the air conditioner remote control at the receiver window of the infrared control module and presses the "Dehumidification Mode" button. The infrared control module receives and stores the infrared code. The controller then binds and stores this code with humidity trigger conditions.

[0055] The communication module supports Wi-Fi and Bluetooth communication protocols for communication with mobile terminal apps and cloud servers, enabling remote control, voice interaction, and health report push notifications. The controller supports OTA remote firmware upgrades.

[0056] The controller is configured to execute the following control strategy: Oxygen concentration graded control strategy: When the indoor oxygen concentration is lower than the first preset threshold, the oxygen generation module and the fresh air module are activated simultaneously according to a preset ratio; when the indoor oxygen concentration is higher than the second preset threshold, the oxygen generation module is suspended; when the indoor oxygen concentration is between the first preset threshold and the second preset threshold, the normal oxygen supply mode is maintained.

[0057] In the oxygen concentration graded control strategy, the first preset threshold is 22%, the second preset threshold is 25%, and the preset ratio is fresh air volume: oxygen production volume = 80:1. When the indoor oxygen concentration is below 22%, oxygen is supplied according to the preset ratio. When the indoor oxygen concentration is above 25%, the oxygen production module is automatically suspended. When the indoor oxygen concentration is between 21% and 24%, the normal mode is maintained.

[0058] The specific implementation method is as follows: The controller calculates the total amount of oxygen needed based on the difference between the current indoor oxygen concentration and the target concentration of 21%. It then calculates the fresh air volume and oxygen production volume at an 80:1 ratio, achieving precise oxygen supply by adjusting the fresh air fan speed and the working power of the oxygen production module. When the indoor oxygen concentration is higher than 25%, the controller pauses the oxygen production module. When the indoor oxygen concentration is between 21% and 24%, the controller maintains the normal mode, only maintaining a basic fresh air volume (e.g., 30m³ / h). 3 / h) to maintain air circulation, the oxygen generation module is in standby mode.

[0059] Temperature and humidity coordinated control strategy: When the indoor humidity is higher than the preset humidity threshold, the air conditioner dehumidification mode is activated in conjunction with the infrared control module. The temperature and humidity coordinated control strategy also includes: activating the humidification module when the indoor humidity is lower than 40%RH, and activating the air conditioner dehumidification mode in conjunction with the infrared control module when the indoor humidity is higher than 60%RH, so as to maintain the indoor humidity between 40% and 60%RH.

[0060] The specific execution method is as follows: When the temperature and humidity sensor detects that the indoor humidity is below 40%RH, the controller directly starts the humidification module, and the atomizing water tank begins atomizing humidification. When the indoor humidity is above 60%RH and remains above 60%RH for more than 5 minutes, the controller sends a trigger signal to the infrared control module. The infrared control module retrieves the corresponding infrared code from its memory and sends a dehumidification command to the air conditioner through the infrared transmitter, thus activating the air conditioner's dehumidification mode. To avoid repeated transmissions, the controller sets the command transmission interval to 3 minutes, sending it only again when the humidity continues to exceed the standard.

[0061] Extensive experimental verification has established 22% as the threshold for initiating oxygen supply, 25% as the threshold for suspending oxygen supply, and 21%-24% as the normal maintenance range. The 80:1 ratio of fresh air volume to oxygen production is the optimal ratio derived from gas dynamics calculations and human physiological studies, effectively balancing indoor oxygen replenishment and carbon dioxide removal. The humidity control range of 40%-60%RH meets human comfort standards and is also the optimal humidity range for inhibiting bacterial and mold growth.

[0062] The control system uses multiple sensors to perceive indoor environmental parameters in real time and automatically adjusts the equipment's operating status based on preset control strategies. The oxygen concentration tiered control strategy differs from the traditional simple binary control of "turning on when below the threshold and turning off when above the threshold." Instead, it introduces refined proportional control and a multi-mode switching mechanism: when the oxygen concentration is too low, oxygen production and fresh air intake are activated simultaneously in proportion, using a large proportion of fresh air to replace exhaust gas while precisely compensating for the oxygen molecules carried away by the exhaust gas with a small proportion of oxygen production, achieving a dynamic balance between oxygen concentration and air quality; when the oxygen concentration is too high, oxygen production is suspended to avoid resource waste; and when the oxygen concentration is within the normal range, the normal mode is maintained. The temperature and humidity coordinated control strategy enables cross-domain linkage with the air conditioning system. When the humidity is too high, the air conditioning system automatically starts dehumidifying; when the humidity is too low, the humidification module automatically humidifies, ensuring that the indoor humidity remains within a comfortable range.

[0063] As a further definition of the control system, the controller is also configured to execute an adaptive proactive adjustment strategy based on multi-sensor fusion: by collaboratively processing multimodal environmental data through edge computing and cloud computing, proactive automatic closed-loop adjustment of environmental parameters such as temperature, humidity, oxygen concentration, PM2.5, TVOC, and formaldehyde is achieved. Edge computing is responsible for real-time data acquisition, filtering, and local rule execution (such as threshold triggering and PID control), ensuring that the system can still operate independently when the network is interrupted; cloud computing is responsible for historical data storage, model training, strategy optimization, and remote configuration updates. Through the collaboration between the edge and the cloud, the system can learn user habits and environmental change patterns, achieving proactive and seamless automatic closed-loop adjustment.

[0064] As a further limitation of the control system, the communication module supports Wi-Fi and / or Bluetooth communication protocols for communication with a mobile terminal APP, enabling remote control, voice interaction, and health report push notifications; the controller supports OTA remote firmware upgrades. Users can view indoor environmental data, remotely control equipment operating status, and perform voice interactions anytime, anywhere via a mobile APP. The system can generate health reports based on historical data and push them to the user's mobile phone. The OTA remote firmware upgrade function allows the device to continuously receive functional enhancements, performance optimizations, and bug fixes, realizing the product's scalability, iterability, and extensibility.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
