Description

Technical Field

[0001] The present invention relates to an indoor air purification system, and in particular, by installing a gas detection module in each air purification device to perform air pollution detection and coordinated control operations, regarding the air pollution state of the indoor area, air pollution data output based on the predicted time detected by a plurality of the gas detection modules meets the requirements of the clean room level. The present invention relates to an indoor air purification system.

Background Art

[0002] Suspended particles refer to solid particles or droplets contained in gas. Since the particle size is very small, it easily penetrates through the nasal hairs in the nasal cavity into the human lungs, causing lung inflammation, asthma, cardiovascular diseases, etc. When other pollutants adhere to the suspended particles, the harm to the respiratory system becomes even greater. In recent years, the problem of air pollution has become increasingly serious. In particular, the concentration data of fine suspended particles (for example, PM2.5) is often too high, and the concentration monitoring of suspended particles in gas has attracted attention. However, the gas flow is unstable due to wind direction and air volume, and most of the current gas monitoring stations for detecting suspended particles are fixed-point type, so the surrounding suspended particle concentration cannot be confirmed immediately.

[0003] In addition, modern people increasingly value the air quality around their lives. For example, gases such as carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM2.5, nitrogen monoxide, sulfur monoxide, and further particles contained in the gas are all exposed to the environment, affecting human health and in serious cases, even endangering life. Therefore, the quality of environmental gas has attracted the attention of various countries, and how to detect the quality of gas to avoid or stay away from areas with poor gas quality has become an issue attracting current attention.

[0004] As a method for checking the quality of gas, it is possible to detect ambient environmental gas using a gas sensor. If it is possible to provide detection information in real time to warn people in the environment and prevent or avoid in real time the impact on and injury to human health caused by gas hazards in the environment, detecting the surrounding environment using a gas sensor can be said to be a very good application.

[0005] In addition, it is difficult to grasp the indoor air quality. In addition to the outdoor air quality, the air conditioning situation and pollution sources indoors are all the main factors affecting the indoor air quality. It is currently an issue in research and development to be able to detect indoor air pollution sources intelligently and quickly in various areas indoors, effectively remove indoor air pollution, form a clean and safe breathable gas state, and monitor the indoor air quality in real time at any time and anywhere. Of course, in the indoor area, if the concentration of suspended particles is strictly controlled according to the "Clean Room" standard, the introduction, generation, and retention of particles can be avoided, and the temperature and humidity can be controlled within the required range. That is, the indoor area is distinguished by its level according to the number of suspended particles in the air, and the clean room requirements for a safely breathable indoor area are achieved.

[0006] In the air pollution detection of the currently provided indoor air purification system, a gas detector detects and transmits air pollution information, and a cloud computing service device receives, stores, and forms a database of the air pollution data of the outdoor area and the indoor area through communication, and performs intelligent calculation and comparison based on the air pollution data, thereby issuing control commands intelligently and selectively, transmitting them to the air guiding device of the air purification device to start the control operation, continuously generating an internal circulation-oriented airflow in the indoor area, guiding the air pollution, and filtering and removing it multiple times by the filtering components, so that the gas state of the indoor area reaches the clean room level formed by the cleanliness standard of the number of particles of suspended particles.

[0007] In addition, in an indoor air purification system, a plurality of air purification devices and a control device are arranged indoors for coordinated control, so as to monitor the indoor air quality in real time, process and filter and purify it in real time, purify the indoor air pollution to approach zero, and form a breathable air state. This has become the main issue in the research and development of the present invention.

When the air pollution data of the indoor area A is higher than the air pollution data of the outdoor area B, the cloud computing service device 4 issues a control command. The gas detection module 1 of the gas exchange device 2a receives the control command via wireless or wired communication, transmits it to the drive control component 23, and controls the startup operation of the air guiding device 21, so as to introduce the gas in the outdoor area B into the indoor area A for ventilation.

[0032] ​In this embodiment, the filtration component 22 of the present invention can further provide a sterilization effect on air pollution in combination with physical or chemical materials, and the air flow path direction of the air guiding device 21 is the direction indicated by the arrow. As shown in FIG. 3B, by applying a decomposition layer to the filtration component 22, air pollution is chemically sterilized and removed. The decomposition layer may be activated carbon 22a, which removes organic and inorganic substances in air pollution and removes colored and odoriferous substances. The decomposition layer may be a chlorine dioxide cleaning factor 22b, which suppresses viruses, bacteria, fungi, influenza A virus, influenza B virus, enterovirus, and norovirus in air pollution, with the suppression rate reaching 99% or more, contributing to reducing the cross-infection of viruses. The decomposition layer may be a herb protection layer 22c containing ginkgo and Rhus chinensis, which effectively resists allergies and destroys the surface proteins of influenza viruses (such as H1N1). The decomposition layer may be silver ions 22d, which suppress viruses, bacteria, and fungi in the introduced air pollution. The decomposition layer may be zeolite 22e, which removes ammonia nitrogen, heavy metals, organic pollutants, Escherichia coli, phenol, chloroform, and anionic surfactants.

The light irradiation is a photocatalyst unit including a photocatalyst 22f and an ultraviolet lamp 22g. When the photocatalyst 22f is irradiated by the ultraviolet lamp 22g, it can convert light energy into electrical energy, decompose harmful substances in air pollution, and achieve the effect of filtering and sterilization through disinfection and sterilization. The light irradiation may be a photo plasma unit including a photo nanotube 22h. By irradiating the introduced air pollution with the photo nanotube 22h, oxygen molecules and water molecules in the air pollution are decomposed into highly oxidizing photo plasma, forming an ion airflow with destroyed organic molecules, decomposing gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOCs) contained in the air pollution into water and carbon dioxide, and achieving the effect of filtering and sterilization. In this embodiment, as shown in FIG. 3D, the air purifier 2 is further provided with an ultraviolet lamp component 26. The ultraviolet lamp component 26 includes a relay 26a.

[0034] In some embodiments, the filtering component 22 can also chemically sterilize and remove air pollution in combination with a decomposition unit. The decomposition unit may be a negative ion unit 22i, which can attach the positively charged particles contained in the introduced air pollution to the negatively charged dust collecting plate, and achieve the effect of filtering and sterilizing the introduced air pollution.

[0035] Referring to FIG. 5, the cloud computing service device 4 includes a wireless network cloud computing service module 41, a cloud control service unit 42, a device management unit 43, and an application unit 44. The wireless network cloud computing service module 41 receives air pollution data information from the gas detection modules 1 in the outdoor area B and the indoor area A, and receives air pollution data information from the gas detection modules 1 built in a plurality of air purification devices 2 (gas exchange device 2a, circulation filtration device 2b, negative pressure exhaust fan 2c, smoke exhaust device 2d, bathroom / toilet exhaust fan 2e), and issues a control command. The wireless network cloud computing service module 41 receives air pollution data information in the indoor area A and the outdoor area B, and transmits it to the cloud control service unit 42. The cloud control service unit 42 stores the air pollution data information to form a database of air pollution data, executes intelligent calculations, compares the air pollution database, issues a control command, transmits it to the wireless network cloud computing service module 41, and transmits it to the devices (air purification device 2, central control device 3, gas exchange device 2a) via the wireless network cloud computing service module 41 to control the startup operation. The device management unit 43 can receive the communication information of a plurality of air purification devices 2 (gas exchange device 2a, circulation filtration device 2b, negative pressure exhaust fan 2c, smoke exhaust device 2d, bathroom / toilet exhaust fan 2e) via the wireless network cloud computing service module 41 for user login management and device binding management, and provide device management information to the application unit 44 for system control management. The application unit 44 displays and notifies the air pollution information obtained by the cloud control service unit 42, so that the user can grasp the air pollution removal situation in real time via a mobile phone or a communication device, and control the operation of the indoor air purification system via the application unit 44 of the mobile phone or the communication device.

[0036] As can be understood from the above description, the present invention provides an indoor air purification system. In a specific implementation, each air purification device 2 in the room is installed with a gas detection module 1 that detects air pollution, transmits air pollution data, receives a control command, and is electrically connected to the drive control component 23 of the air purification device 2. The drive control component 23 controls the startup operation of the air guiding device 21 of the air purification device 2 and receives the air pollution data output from the gas detection module 1 via wireless or wired communication. The use of wireless or wired communication can be realized by selecting a communication mechanism that can be transmitted from the dual methods of wired communication and wireless communication. Under the monitoring mechanism of the actual handshake communication protocol of wired communication and wireless communication, it is an alternative mechanism that autonomously determines the wired communication capable of transmission communication or the wireless communication capable of transmission communication, and transmits the air pollution data output by air pollution detection to the cloud computing service device 4. The cloud computing service device 4 generates a control command, feedbacks it to the gas detection module 1, and transmits it to the drive control component 23 that is electrically connected. The drive control component 23 controls the startup operation of the air guiding device 21 of the air purification device 2 and realizes countermeasures for the detection disconnection prevention mechanism to be solved by wireless or wired communication. Also, when the air pollution data detected and output by the gas detection module 1 is disconnected from both wired communication and wireless communication, the gas detection module 1 autonomously calculates and compares the air pollution data, autonomously issues a control command, and transmits it to the drive control component 23 of the air purification device 2 to control the startup operation of the air guiding device 21. Thus, the air guiding device 21 starts under control and guides the air pollution to be filtered by the filtering component 22, so that the air pollution state in the indoor area A meets the requirements of the clean room level based on the detection time.

[0037] Furthermore, in the indoor air purification system provided by the present invention, the loud computing service device 4 receives the air pollution data of the indoor area A and the outdoor area B through wireless or wired communication, stores it to form a database of air pollution data, performs intelligent computing and comparison based on the database of air pollution data, issues control commands intelligently and selectively, and transmits them to the air guiding device 21 of the air purification device 2 to start the control operation, so as to continuously generate an internal circulation-oriented airflow in the indoor area A, guide air pollution, and filter and remove it multiple times by the filtering component 22. That is, the cloud computing service device 4 intelligently calculates the cleanliness of the real-time particle number of suspended particles in the indoor area A, issues control commands intelligently and selectively, and transmits them to a plurality of air purification devices 2 to timely start and control the operation of the air guiding device 21 of the air purification device 2. According to the cleanliness of the real-time particle number of suspended particles, the air volume and start-up time of the air guiding device 21 can be randomly adjusted, improving the cleaning efficiency of the indoor area A, reducing the environmental noise of the indoor area A, generating an internal circulation-oriented airflow in the indoor area A, quickly guiding air pollution, and filtering and removing it multiple times by the filtering component 22, so that the air pollution state of the indoor area A meets the requirements of the clean room level according to the detection time.

[0038] As the requirements of the above clean room level, the clean room ZAP Clean Room levels 1 to 9 are equivalent to the cleanliness of the clean room ISO levels 1 to 9. However, the clean room ZAP Clean Room 1 to 9 has a different technical architecture from the conventional clean room ISO levels 1 to 9 and can achieve the same indoor air cleanliness as the conventional clean room ISO levels 1 to 9. Generally, in the conventional clean room ISO levels 1 to 9, since there is no sensor for 24-hour real-time detection, it is necessary to operate at high speed for 24 hours. In such an operation method, a large amount of energy loss occurs, leading to a high-noise environment, and such a system cannot be used in general indoor household life. The general household environment standard is the clean room ZAP Clean Room level 6 of the present invention +, 6, 6 - and Clean Room ZAP Clean Room Level 7 + , 7, 7 - is in compliance with. Clean Room ZAP Clean Room Level 6 + , 6, 6 - The cleanliness of is equivalent to the cleanliness of ISO Level 6, and the cleanliness of Clean Room ZAP Clean Room Level 7 + , 7, 7 - is equivalent to the cleanliness of ISO Level 7.

[0039] The indoor air purification system of the present invention is of Clean Room ZAP Clean Room Level 6 + , 6, 6 - and Clean Room ZAP Clean Room Level 7 + , 7, 7 - belongs to. The indoor air purification system of the present invention uses a gas detection module built in a plurality of air purification devices (gas exchange device 2a, circulation filtration device 2b, negative pressure exhaust fan 2c, smoke exhaust device 2d, bathroom / toilet exhaust fan 2e) and a cloud computing service device to form an intelligent cooperation system, and uses a gas detection module outside or inside the device to detect PM2.5 concentration / particle number, carbon dioxide (CO2), carbon monoxide (CO), formaldehyde, volatile organic compounds (TVOC), ozone (O3), bacteria, and fungi. It is connected to the cloud computing service device via wired or wireless communication transmission, and the cloud computing service device executes intelligent operations and selectively provides control command signals to the gas detection modules of the plurality of air purification devices to control the startup operation, air volume speed, and noise of the air guiding device, thereby realizing a quiet and highly efficient Clean Room ZAP Clean Room system.
