Background Art

[0002] Modern people pay more and more attention to the gas quality around their lives. For example, gases such as carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), PM2.5, nitric oxide, sulfur monoxide, etc., and even the particles contained in the gas will be exposed in the environment and affect human health, and in severe cases, even endanger life. Therefore, the quality of environmental gases has attracted the attention of various countries. How to detect gas quality to avoid and stay away from areas with poor gas quality is a current important topic.

[0003] To confirm the quality of gas, it is feasible to use a gas sensor to detect the surrounding environmental gas. If it can also provide detection information in real time and alert people in the environment, enabling them to prevent or escape in time and avoid being harmed by the gas in the environment and causing impacts and injuries to human health, using a gas sensor to detect the surrounding environment can be said to be a very good application.

[0004] Moreover, it is not easy to master the indoor air quality. In addition to the outdoor air quality, the indoor air conditioning conditions and pollution sources are the main factors affecting the indoor air quality. It is possible to quickly and intelligently detect indoor air pollution sources in various indoor areas, effectively remove indoor air pollution to form a clean and breathable gas state, and can monitor the indoor air quality at any time and place. Of course, if the indoor area can strictly control the concentration of airborne particles according to the "clean room" standard, strive to avoid the introduction, generation and retention of particles, and control its temperature and humidity within the required range, that is, the indoor area is distinguished by the number of suspended particles in the air to meet the clean room requirements of a breathable indoor area.

[0005] The air pollution detection of the currently provided indoor air purification method is to detect and transmit air pollution information by a gas detector, and then transmit it through communication to a cloud computing service device to receive the air pollution data of the outdoor field and the indoor field and store it to form a database of air pollution data. And based on the intelligent calculation and comparison of the air pollution data, an intelligent selection is made to send a control instruction to the fan of the air purification device to start the regulation operation, so that an internal circulation directed air flow is continuously generated in the indoor field, and the air pollution is drained through the filter element for filtration and removal multiple times, so that the gas state of the indoor field can reach the cleanliness level of the clean room formed by the cleanliness specification of the number of suspended particulate particles, and how to provide an indoor air purification method that can achieve the requirements of the true and actual clean room ZAP Clean room 6+, 6, 6-, 7+, 7, 7- levels in the air pollution state of the indoor field, and meet the best setting cost of the air purification device, the lowest required power consumption, the best operating efficiency, and the lowest noise to achieve instant cleaning treatment. This is the main research topic developed by the present invention. Summary of the Invention

[0052] Examples embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different aspects, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are for illustrative purposes in essence and are not intended to limit the present invention.

[0053] Please refer to Figure 1 As shown, the present invention provides an indoor air purification method, including the following steps:

[0054] Step a: Provide an indoor air purification system to perform air pollution detection and purification treatment in an indoor area. The indoor air purification system includes multiple gas detection modules 1 to detect air pollution in the indoor area and output air pollution data of the indoor area, and multiple air purification devices 2 to purify the air pollution in the indoor area. It should be noted that, as Figure 3 shown, the indoor air purification system mainly includes multiple gas detection modules 1, multiple air purification devices 2, and at least one central control and regulation device 3. Among them, the gas detection module 1 is a sensing element for detecting air pollution, arranged in the indoor area or outdoor area to detect air pollution and output air pollution data. The air purification device 2 is arranged in the indoor area and includes a fan 21, a filter element 22, and a drive control component 23, and a built-in gas detection module 1 is directly electrically connected inside the air purification device 2. The gas detection module 1 of the air purification device 2 is electrically connected to the fan 21 and the drive control component 23. The gas detection module 1 detects air pollution to generate air pollution data of the indoor area, performs arithmetic processing, and outputs several regulation signals to regulate the start, air volume, and noise level of the fan 21, so that the fan 21 is controlled to start and draw air pollution through the filter element 22 for filtration. The central control and regulation device 3 is connected to the gas detection module 1 of the air purification device 2, provides a control command signal to the gas detection module 1 through communication connection to regulate the operation of the fan 21, and receives the air pollution data signal detected by the gas detection module 1 for immediate display.

[0055] Step b: Provide a reference suspended particulate matter (PM) air quality data based on intelligent arithmetic comparison in the field air quality database, depending on the number of air purification devices and the sampling period in the indoor area. The indoor air purification system provides a cloud computing service device 4, and the cloud computing service device 4 sets up a field air quality database, collects the air pollution data detected and output by the gas detection modules 1 of multiple air purification devices 2 received through communication, and collects the suspended particulate matter (PM) air quality data of a specific field, and provides a reference suspended particulate matter (PM) air quality data through intelligent arithmetic comparison to determine the number of air purification devices 2 to be set and the sampling period in the indoor area for the indoor air purification system. It should be noted that, as Figure 2AAs shown, the indoor air purification system provides a cloud computing service device 4. The cloud computing service device 4 sets up a field air quality database to collect the air pollution data detected and output by the gas detection modules 1 of multiple air purification devices 2 through communication, and to collect the suspended particulate matter (PM) air quality data of a specific field.

[0068] As Figure 4A and Figure 4B shown, the specific implementation manner of an indoor air purification system proposed by the present invention in the indoor field A can be understood. The following describes multiple air purification devices 2 specifically implemented in the indoor field A. This air purification device 2 can be set in the indoor field A in an embedded (Build-in) or plug-in (Plug-in) manner. If the air purification device 2 is set in the indoor field A in an embedded (Build-in) manner (as Figure 4A and Figure 4B shown), therefore, at least one circulating return air channel C is set in the indoor field A, which is formed by being surrounded and isolated by several partitions C1 on the side of the indoor field A, and is provided with multiple air intake ports C2 and multiple air return ports C3.

[0069] The above air purification device 2 can be a gas exchanger 2a, which is arranged in the circulating return air duct C of the indoor field A, corresponds to the air intake C2, and has a channel to communicate with the outdoor field B (not shown) for ventilation. The gas detection module 1 of the gas exchanger 2a receives a control instruction through wireless or wired communication and transmits it to the drive control component 23 to regulate the start and operation of the fan 21, as well as at least one gas detection module 1 arranged in the outdoor field B and at least one gas detection module 1 arranged in the indoor field A. The cloud computing service device 4 receives the air pollution data of the indoor field A and the outdoor field B, stores it to form a database of air pollution data, and intelligently calculates and compares the air pollution data of the indoor field A and the outdoor field B. When the air pollution data of the indoor field A is higher than that of the outdoor field B, the cloud computing service device 4 issues a control instruction through wireless or wired communication to the gas detection module 1 of the gas exchanger 2a. The gas detection module 1 receives the control instruction and transmits it to the drive control component 23 to regulate the start and operation of the fan 21, so as to introduce the gas in the outdoor field B into the indoor field A for ventilation. It should be noted that the gas detection modules 1 in the outdoor field B and the indoor field A detect the air pollution data of carbon dioxide (CO2). The air pollution data of carbon dioxide (CO2) detected by the gas detection module 1 must be maintained below a set safety value of 800 PPM. When the air pollution data exceeds the set safety value, the gas exchanger 2a provides the gas in the outdoor field B to be introduced into the indoor field A for ventilation. It should be noted that the gas exchanger 2a can be a fresh air fan or a total heat exchanger.

[0070] The above air purification device 2 can be a circulating filtration device 2b, which is arranged in the circulating return air duct C of the indoor field A, corresponds to the air intake C2, and filters the drained air pollution through the filter element 22 and discharges it into the space of the indoor field A through the air intake C2. The gas detection module 1 of the circulating filtration device 2b transmits the air pollution data externally through wireless or wired communication to the cloud computing service device 4 for reception to form a database of air pollution data, and intelligently calculates and compares it, and then intelligently selects and issues a control instruction. The gas detection module 1 receives it through wireless or wired communication and then transmits it to the drive control component 23 to regulate the start and operation of the fan 21 of the circulating filtration device 2b. The drained air pollution is filtered through the filter element 22 and enters the space of the indoor field A, so that the air pollution state of the indoor field A is calibrated according to the detection time and meets the requirements of the clean room grade.

[0071] Such as Figure 4A , Figure 4B and Figure 4CAs shown, the above-mentioned air purification device 2 can be a negative pressure exhaust fan 2c. The negative pressure exhaust fan 2c is arranged at the position of the kitchen unit A1 in the indoor field A, and the negative pressure exhaust fan 2c is arranged in the circulating return air channel C of the indoor field A, and has a channel connection (not shown) to the outdoor field B to accelerate the discharge of air pollutants in the indoor field A to the outside of the outdoor field B. The gas detection module 1 of the negative pressure exhaust fan 2c transmits air pollution data externally to the cloud computing service device 4 for reception to form a database of air pollution data, and performs intelligent calculation and comparison, and then intelligently selects and issues a control instruction. The gas detection module 1 receives it through wireless or wired communication, and then transmits it to the drive control component 23 to regulate the start and operation of the negative pressure exhaust fan 2c, and guides the air pollutants to be filtered through the filter element 22, so as to accelerate the discharge of the air pollutants in the indoor field A to the outside of the outdoor field B. It should be noted that in the embodiment of the present invention, the negative pressure exhaust fan 2c is arranged in front of the cooking device D to directly suck and discharge the air pollutants outside, so that the cook cannot smell the oil fumes and prevent the air pollutants from spreading to other spaces such as the living room space, but it is not limited thereto.

[0072] As Figure 4A , Figure 4B and Figure 4C shown, the above-mentioned air purification device 2 can be a range hood 2d. The range hood 2d is arranged at the position of the kitchen unit A1 in the indoor field A, and the range hood 2d is arranged in the circulating return air channel C of the indoor field A, and has a channel connection (not shown) to the outdoor field B to accelerate the discharge of air pollutants in the indoor field A to the outside of the outdoor field B. The gas detection module 1 of the range hood 2d transmits air pollution data externally to the cloud computing service device 4 for reception to form a database of air pollution data, and performs intelligent calculation and comparison, and then intelligently selects and issues a control instruction. The gas detection module 1 receives it through wireless or wired communication, and then transmits it to the drive control component 23 to regulate the start and operation of the fan 21 of the range hood 2d, and guides the air pollutants to be filtered through the filter element 22, so as to accelerate the discharge of the air pollutants in the indoor field A to the outside of the outdoor field B.

[0073] The above air purification device 2 can be a bathroom exhaust fan 2e, which is arranged at the position of the bathroom unit A2 in the indoor area A. The bathroom exhaust fan 2e is arranged in the circulating return air duct C of the indoor area A and has a channel (not shown) communicating with the outdoor area B to accelerate the discharge of indoor air pollutants to the outdoor area B. The gas detection module 1 of the bathroom exhaust fan 2e transmits the air pollutant data to the cloud computing service device 4 for receiving and forming a database of air pollutant data, and performs intelligent calculation and comparison, and then intelligently selects and issues a control instruction. The gas detection module 1 receives it through wireless or wired communication and then transmits it to the drive control component 23 to control the start and operation of the fan 21 of the bathroom exhaust fan 2e. The air pollutants are drained and filtered through the filter element 22, so that the air pollutants in the indoor area A are accelerated and discharged to the outdoor area B, and at the same time, the temperature and humidity of the bathroom unit A2 in the indoor area A are regulated. It should be noted that the temperature and humidity regulation is to maintain the temperature in the bathroom unit A2 in the indoor area A within the range of 25°C ± 3°C and the humidity within the range of 50% ± 10%.

[0074] Please also refer to Figure 5A 、 Figure 5B As shown, the fan 21 of the above air purification device 2 is controlled to start, and the air pollutants are drained and filtered through the filter element 22. The filter element 22 can be of the ultra-high efficiency particulate air (ULPA) grade or the high efficiency particulate air (HEPA) filter, which adsorbs chemical smog, bacteria, dust particles and pollen contained in the air pollutants, so as to achieve the effect of filtering and purifying the introduced air pollutants.

[0075] In this embodiment, physical or chemical property materials can be further combined on the filter element 22 of the present invention to provide a bactericidal effect on the passing air pollutants. And the air flow path direction of the fan 21 is the direction shown by the arrow. Therefore, as Figure 5B shown, on the filter element 22, the passing air pollutants are sterilized and removed by coating a decomposition layer chemically. The decomposition layer can be an activated carbon 22a, which removes organic and inorganic substances in the air pollutants and removes colored and odorous substances. The decomposition layer can be a chlorine dioxide cleaning factor 22b, which can inhibit viruses, bacteria, fungi, influenza A virus, influenza B virus, enterovirus, and norovirus in the air pollutants by more than 99%, helping to reduce the cross-infection of viruses. The decomposition layer can be a herbal care layer 22c of ginkgo and Japanese sumac, which can effectively resist allergies and destroy the surface proteins of influenza viruses (such as H1N1). The decomposition layer can be a silver ion 22d, which can inhibit viruses, bacteria, and fungi in the introduced air pollutants. The decomposition layer can be a zeolite 22e, which can remove ammonia nitrogen, heavy metals, organic pollutants, Escherichia coli, phenol, chloroform, and silver ion surfactants.

[0076] In some embodiments, the filter element 22 can also be combined with a chemical method of light irradiation to sterilize and remove air pollutants. 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 the air pollutants and disinfect, so as to achieve the effect of filtration and sterilization. The light irradiation can be a photo-plasma unit of a nano-light tube 22h. By irradiating the introduced air pollutants through the nano-light tube 22h, the oxygen molecules and water molecules in the air pollutants are decomposed into highly oxidizing photo-plasmas, forming an ion flow with the ability to destroy organic molecules, and decomposing gas molecules such as volatile formaldehyde, toluene, and volatile organic compounds (VOCs) in the air pollutants into water and carbon dioxide, achieving the effect of filtration and sterilization. It should be noted that in this embodiment, the air purification device 2 is further provided with an ultraviolet lamp assembly to control the start and regulation of the ultraviolet lamp 22g. The ultraviolet lamp 22g is arranged on one side of the filter element 22 to sterilize the passing air pollutants.

[0077] In some embodiments, the filter element 22 can also be combined with a chemical method of a decomposition unit to sterilize and remove air pollutants. The decomposition unit can be a negative ion unit 22i, which makes the particles contained in the introduced air pollutants carry positive charges and attach to the negatively charged ones, achieving the effect of filtering and sterilizing the introduced air pollutants. The decomposition unit can be a plasma ion unit 22j. Through the plasma ions, the oxygen molecules and water molecules contained in the air pollutants are ionized to generate cations (H+) and anions (O2-). After the substances with water molecules attached around the ions attach to the surfaces of viruses and bacteria, under the action of chemical reactions, they will be converted into highly oxidizing reactive oxygen (hydroxyl, OH groups), thereby taking away the hydrogen of the surface proteins of viruses and bacteria and oxidizing and decomposing them, so as to achieve the effect of filtering and sterilizing the introduced air pollutants.

[0078] As can be seen from the above description, the present invention provides an indoor air purification system. In a specific implementation, a gas detection module 1 is provided on each indoor air purification device 2 to implement air pollution detection, transmit air pollution data, and receive control instructions and be electrically connected to the drive control component 23 of the air purification device 2. The drive control component 23 regulates the start and operation of the fan 21 of the air purification device 2, and the output of the air pollution data by the gas detection module 1 is transmitted and received through wireless or wired communication. It can be realized by using a dual mode of wired communication and wireless communication to select an operable transmission communication mechanism. Under the monitoring mechanism of the actual handshaking communication protocol for wired communication and wireless communication, it independently judges and selects an operable wired communication for transmission communication or an operable wireless communication for transmission communication to transmit the air pollution data output by the air pollution detection to the cloud computing service device 4. Then, the cloud computing service device 4 generates a control instruction and feeds it back to the gas detection module 1 for transmission to the electrically connected drive control component 23, and the drive control component 23 regulates the start and operation of the fan 21 of the air purification device 2, realizing a detection disconnection prevention mechanism measure to be solved by wireless or wired communication; in addition, in the case of double disconnection communication of wired communication and wireless communication for the air pollution data output by the gas detection module 1, the gas detection module 1 can independently calculate and compare the air pollution data, and independently issue a control instruction for transmission to the drive control component 23 of the air purification device 2 to regulate the start and operation of the fan 21, so that the fan 21 is controlled to start and drain air pollution through the filter element 22 for filtration, so that the air pollution state of the indoor field A is calibrated by the detection time, meeting the clean room grade requirements.

[0079] In addition, for the indoor air purification system provided by the present invention, the cloud computing service device 4 receives the air pollution data of the indoor field A and the outdoor field B through wireless or wired communication and stores it to form a database of air pollution data. And based on the intelligent calculation and comparison of the database of air pollution data, it intelligently selects and issues a control instruction to the fan 21 of the air purification device 2 to start the regulation operation, so that the indoor field A continuously generates an internal circulation directed air flow, and drains the air pollution through the filter element 22 for filtration and removal multiple times; that is to say, the cloud computing service device 4 intelligently calculates the cleanliness of the suspended particulate matter particles in the indoor field A in real time, and intelligently selects and issues a control instruction for transmission to multiple air purification devices 2, timely mobilizing and controlling the start of the fan 21 of the air purification device 2, and being able to randomly change and adjust the air volume and start time period of the fan 21 according to the cleanliness of the suspended particulate matter particles in real time, improving the purification efficiency of the indoor field A and reducing the environmental noise of the indoor field A, so that the indoor field A generates an internal circulation directed air flow, quickly drains the air pollution through the filter element 22 for filtration and removal multiple times, and makes the air pollution state of the indoor field A meet the requirements of clean room grades ZAP Clean room 6+, 6, 6-, 7+, 7, 7-.

[0080] The above cleanroom grade requirements state that the cleanliness grades of ZAP Clean room 1 to 9 are equivalent to those of ISO Cleanroom 1 to 9. However, ZAP Clean room 1 to 9 has a technical framework different from the traditional ISO Cleanroom 1 to 9 grades and can achieve the same indoor air cleanliness as the traditional ISO Cleanroom 1 to 9 grades. Generally, traditional ISO Cleanroom 1 to 9 grades do not have sensors for round-the-clock real-time detection, so it needs to operate at high speed for 24 hours a day. Such an operation mode will result in a large amount of energy loss and a high-noise environment, and such a system cannot be applied to general indoor home life. General home environment specifications conform to the ZAP Clean room 6+, 6, 6- grades and the ZAP Clean room 7+, 7, 7- grades of this invention. The cleanliness grades of ZAP Clean room 6+, 6, 6- are the same as ISO 6 grade cleanliness, and the cleanliness grades of ZAP Clean room 7+, 7, 7- are the same as ISO 7 grade cleanliness.

[0081] The indoor air purification system of this invention belongs to the ZAP Clean room 6+, 6, 6- grades and the ZAP Clean room 7+, 7, 7- grades. The indoor air purification system of this invention utilizes multiple air purification devices 2 (gas exchanger 2a, circulating filtration device 2b, negative pressure exhaust fan 2c, smoke exhaust machine 2d, bathroom exhaust fan 2e) with built-in gas detection module 1 and cloud computing service device 4 to form an intelligent linkage system. The gas detection module 1 set outside and inside the equipment is used to detect the PM2.5 concentration / particle number, carbon dioxide (CO2), carbon monoxide (CO), formaldehyde, total volatile organic compounds (TVOC), ozone (O3), bacteria, and fungi, and can be transmitted through wired or wireless communication to connect to the cloud computing service device 4. The intelligent operation selects and provides control command signals to the gas detection module 1 of multiple air purification devices 2 to regulate the start operation, air volume speed, and noise level of the fan 21, so as to achieve a quiet and efficient ZAP Clean room system.

[0082] In summary, this invention provides an indoor air purification method. By means of an indoor air purification system in conjunction with the field air quality database and the suspended particulate matter (PM), gas, bacteria, and virus association database set in the cloud computing service device, intelligent operation and comparison provide reference suspended particulate matter (PM) air quality data and harmful gases, bacteria, and fungi.

[0083] MJ24A-1324CN_24A458 1TWCN_The correlation parameters of the virus and the suspended particulate matter (PM) in the simplified Chinese version are determined by referring to the air quality data of the suspended particulate matter (PM) and the air pollution correlation parameters. The optimal number and sampling period of the air purification device are implemented in the indoor field, and the start timing cycle, air volume speed, and noise level required for the air purification device are regulated. In addition, the verification of the air pollution data in the indoor field by the air quality database of the field is carried out, so that this indoor air purification method can meet the requirements of the true and real clean room ZAP Clean room 6+, 6, 6-, 7+, 7, 7- levels in the air pollution state of the indoor field, meet the setting cost of the best air purification device, the lowest required power consumption, the best operating efficiency, and the lowest noise to achieve immediate purification treatment, which has great industrial utilization value.
