CROSS-REFERENCE TO RELATED APPLICATION

[0001]This application claims priorities to Taiwan Patent Application No. 113112219 filed on Mar. 29, 2024 and Taiwan Patent Application No. 113105859 filed on Feb. 19, 2024. The entire contents of the above-mentioned patent applications are incorporated herein by reference for all purposes.

FIELD OF THE INVENTION

[0002]The present disclosure relates to an indoor air cleaning system, and more particularly to an indoor air cleaning system having air cleaning devices cooperated with gas detection modules for air pollution detection, so that an air pollution state of an indoor field specified by accumulated numbers of 1 nm-2.5 μm suspended particulates detected by a plurality of gas detection modules within 24 hours can meet a cleanliness of ZAPClean room 1-12.

BACKGROUND OF THE INVENTION

[0003]Suspended particles are solid particles or droplets contained in the air. Due to their extremely fine size, the suspended particles may enter the lungs of human body through the nasal hairs in the nasal cavity easily, causing inflammation in the lungs, asthma or cardiovascular disease. If other pollutant compounds are attached to the suspended particles, it will further increase the harm to the respiratory system. In recent years, the problem of air pollution is getting worse. In particular, the concentration of particle matters (e.g., PM2.5) is often too high. Therefore, the monitoring to the concentration of the gas suspended particles is taken more and more seriously. However, the gas flows unstably due to variable wind direction and air volume, and the general gas-quality monitoring station is located in a fixed place. Under this circumstance, it is impossible for people to check the concentration of suspended particles in current environment.

[0004]Furthermore, in recent years, modern people are placing increasing importance on the quality of the air in their surroundings. For example, carbon monoxide, carbon dioxide, volatile organic compounds (VOC), PM2.5, nitric oxide, sulfur monoxide and even the suspended particles contained in the air are exposed in the environment to affect the human health, and even endanger the life seriously. Therefore, the quality of environmental air has attracted the attention in various countries. At present, how to detect the air quality and avoid the harm is a crucial issue that urgently needs to be solved.

[0005]In order to confirm the quality of the air, it is feasible to use a gas sensor to detect the air in the surrounding environment. If the detection information can be provided in real time to warn people in the environment, it is helpful of avoiding the harm and facilitates people to escape the hazard immediately, thereby preventing the hazardous gas exposed in the environment from affecting the human health and causing the harm. Therefore, it is considered a valuable application to use a gas sensor to detect the air in the surrounding environment.

[0006]In addition, it is not easy to control the indoor air quality. Besides the outdoor air quality, indoor air-conditioning conditions and pollution sources are the major factors affecting the indoor air quality. It is necessary to intelligently and rapidly detect indoor air pollution sources in various indoor fields, effectively remove the indoor air pollution to form a clean and safe breathing gas state, and monitor the indoor air quality in real time anytime, anywhere. Certainly, if the concentration of the suspended particles in the indoor field is strictly controlled according to the “clean room” standard, it allows of avoiding the introduction, generation and retention of suspended particles, and the temperature and humidity in the indoor field can be controlled within the required range. That is to say, through classifying the indoor field by the number of suspended particles in the air, the indoor field can meet the clean room requirements for safe breathing.

[0007]Currently, the air pollution detection of the indoor air cleaning system is as followed. The gas detector detects and outputs air pollution information, the cloud computing server receives the air pollution information of outdoor field and indoor field, stores the air pollution information to form a database of air pollution data, performs an intelligence computing for comparison based on the air pollution data, and intelligently selects and issues a control command to enable the fan of the air cleaning device to generate a directional circulation airflow for rapidly guiding the air pollution to pass through the filter element multiple times for filtration, thereby reaching a gas state of the indoor field to a cleanroom class by a cleanliness specification based on the number of suspended particles.

[0008]Therefore, it is an issue of concern developed in the present disclosure to provide an indoor air cleaning system which monitors the indoor air quality and filters and cleans the indoor air in real time through a coordinated regulation between plural air cleaning devices and a control device, so as to make the air pollution state of the indoor field which has a space specified by accumulated numbers of 1 nm-2.5 μm suspended particulates detected by plural gas detection modules within 24 hours to meet a cleanliness of ZAPClean room 1-12.

SUMMARY OF THE INVENTION

Through disposing the gas detection module in each of the air cleaning devices in electric connection, the air pollution is detected and the operation is regulated. Moreover, the connection of the central control device to the gas detection modules is achieved through one of the wired communication and the wireless communication selected under the handshake protocol for providing the operation instruction to the gas detection modules to control the enablement, air volume and noise level of the fans of the plurality of air cleaning devices, so as to guide the air pollution to pass through the filter elements of the plurality of air cleaning devices for filtration, thereby making the air pollution state of the indoor field specified by accumulated numbers of 1 nm-2.5 μm suspended particulates detected by the plurality of gas detection modules within 24 hours to meet a cleanliness of ZAPClean room 1-12.

Preferably but not exclusively, the light irradiation element is a photo-catalyst unit including a photo catalyst 22f and an ultraviolet lamp 22g.

Preferably but not exclusively, the light irradiation element is a photo-plasma unit including a nanometer irradiation tube 22h. When the introduced air pollution is irradiated by the nanometer irradiation tube 22h, the oxygen molecules and water molecules contained in the air pollution are decomposed into high oxidizing photo-plasma, and an ion flow capable of destroying organic molecules is generated. In that, volatile formaldehyde, volatile toluene and volatile organic compounds (VOC) contained in the air pollution are decomposed into water and carbon dioxide, so as to achieve the effects of filtration and purification. Notably, in the embodiment, as shown in FIG. 3D, the air cleaning device 2 further includes an ultraviolet lamp assembly 26.

The substances attached with water around the ions are adhered on the surfaces of viruses and bacteria and converted into OH radicals with extremely strong oxidizing power, thereby removing hydrogen (H) from the protein on the surfaces of viruses and bacteria, and thus decomposing (oxidizing) the protein, so as to filter the introduced air pollution and achieve the effects of filtering and sterilization.

[0050]Please refer to FIG. 5. In the embodiment, the cloud computing server 4 includes a wireless network cloud computing service module 41, a cloud control service unit 42, a device management unit 43 and an application program unit 44. The wireless network cloud computing service module 41 receives the air pollution data detected by the gas detection modules 1 of the outdoor field B and the indoor field A, receives communication information of the plurality of air cleaning devices 2 (the gas exchanging device 2a, the circulation filtration device 2b, the negative pressure exhaust fan 2c, the range hood 2d, the bathroom exhaust fan 2e), and transmits the control command. Moreover, the wireless network cloud computing service module 41 receives the air pollution data of the indoor field A and the outdoor field B and transmits thereof to the cloud control service unit 42 to store and form the database of air pollution data, and performs the intelligence computing and comparison based on the database of air pollution data for transmitting the control command to the wireless network cloud computing service module 41 and then to devices, such as the air cleaning device 2, the central control device 3, and the gas exchanging device 2a, for enablement. The device management unit 43 receives the communication information of the plurality of air cleaning devices 2 (the gas exchanging device 2a, the circulation filtration device 2b, the negative pressure exhaust fan 2c, the range hood 2d, the bathroom exhaust fan 2e) through the wireless network cloud computing service module 41 for managing the user login and device binding, and the device management information can be provided to the application program unit 44 for system control and management. The application program unit 44 can also display and inform the air pollution data obtained from the cloud control service unit 42, so the user can know the real-time status of air pollution removal through the mobile phone or the communication device. Moreover, the user can control the operation of the indoor air cleaning system through the application program unit 44 of the mobile phone or the communication device.

[0051]In view of above, the present disclosure provides an indoor air cleaning system. In the specific implementations, each air cleaning device 2 is equipped with a gas detection module 1 for detecting air pollution, outputting air pollution data, and receiving and transmitting the control command to the driving control component 23, which is electrically connected to the air cleaning device 2, so that the driving control component 23 controls the enablement of the fan 21 of the air cleaning device 2. Moreover, the communication utilized by the gas detection module 1 to output the air pollution data includes dual ways, the wired communication and the wireless communication, and through the handshake protocol and autonomous judging, one of the wired communication and the wireless communication which functions normally is selected to perform the transmission of the detected air pollution data to the cloud computing server 4. Then, the cloud computing server 4 generates and feedbacks the control command to the gas detection module 1 for further transmitting to the driving control component 23 electrically connected therewith, so as to control the enablement of the fan 21 of the air cleaning device 2. Whereby, a mechanism for detecting and preventing disconnection of the wireless communication or the wired communication is achieved. On the other hand, if both the wired communication and the wireless communication are disconnected when the gas detection module 1 outputs the air pollution data, the gas detection module 1 autonomously computes and compares the air pollution data, and issues the control command to the driving control component 23 of the air cleaning device 2 to enable the fan 21 for guiding the air pollution to pass through the filter element 22, thereby making the air pollution state of the indoor field A specified by accumulated numbers of 1 nm-2.5 μm suspended particulates detected by the plurality of gas detection modules 1 within 24 hours to meet the cleanliness of ZAPClean room 1-12.

[0052]Furthermore, in the indoor air cleaning system of the present disclosure, by receiving the air pollution data of the indoor field A and the outdoor field B through the wireless communication or the wired communication, storing thereof to form the database of air pollution data, and performing the intelligence computing for comparison based on the database of air pollution data, the cloud computing server 4 intelligently selects and issues the control command to enable the fan 21 of the air cleaning device 2 for continuously generating an internal directional circulation airflow in the indoor field A so as to guide the air pollution to pass through the filter element 22 multiple times for filtration. That is, the cloud computing server 4 intelligently computes the cleanliness of real time number of suspended particulates in the indoor field A and intelligently selects and issues the control command to the plurality of air cleaning devices 2 for timely enabling the fans 21 of the air cleaning devices 2, so that the air volume and start-up period of the fans 21 can be adjusted based on the cleanliness of real time number of suspended particulates, thereby improving the cleaning efficiency of the indoor field A, reducing the environment noise of the indoor field A, and generating the internal directional circulation airflow in the indoor field A to guide the air pollution to pass through the filter element 22 multiple times for filtration. In that, the air pollution state of the indoor field A specified by accumulated numbers of 1 nm-2.5 μm suspended particulates detected by the plurality of gas detection modules 1 within 24 hours can meet the cleanliness of ZAPClean room 1-12.

[0053]The above-mentioned cleanliness specification of ZAPClean room 1-12 is equal to that of ISO 1-9 classes. Although the cleanliness specification of ZAPClean 1-12 has different architecture from that of ISO 1-9 classes, it can identically achieve the cleanliness equal to the conventional ISO 1-9 classes. Generally, the cleanroom of conventional ISO 1-9 classes is not equipped with the sensor for a whole day real time detection, so that the system has to operate in high speed for 24 hours, thereby resulting in large energy consumption and a high-noise environment, which is not applicable to the general living environment.

[0054]The indoor air cleaning system of the present disclosure employs the cleanliness of ZAPClean room 1-12. In the indoor air cleaning system of the present disclosure, the gas detection modules 1 installed in the plurality of air cleaning devices 2 (the gas exchanging device 2a, the circulation filtration device 2b, the negative pressure exhaust fan 2c, the range hood 2d, the bathroom exhaust fan 2e) are utilized to intelligently link to the cloud computing server 4, and the gas detection modules 1 disposed inside and outside the device are used to detect PM2.5 concentration/particle number, carbon dioxide (CO₂), carbon monoxide (CO), formaldehyde, methane, toluene, total volatile organic compounds (TVOC), ozone (O₃), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), radon (Rn-222), bacteria, fungi and virus, so that through the wireless communication or the wired communication, the cloud computing server 4 intelligently computes, selects and issues the control command to the gas detection modules 1 in the plurality of air cleaning devices 2 for controlling the enablement, the air volume and the noise level of the fans 21, thereby achieving a quiet and high efficient system which meets the cleanliness of ZAPClean room.
