[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] Reference Figure 1 As shown, an embodiment of the present invention provides a formaldehyde removal method, which may include the following steps:

[0048] 101. Identify the material types of at least some of the indoor furniture.

[0049] Indoor formaldehyde is primarily emitted by home furnishing materials after renovations are completed. Different decorating materials carry varying levels of formaldehyde and other harmful substances. Generally, pure solid wood contains relatively low levels of formaldehyde, while composite materials contain relatively high levels. By first identifying the materials in a room, we can determine the type of material present. We can then further tailor the indoor temperature and humidity to the specific material type, creating a temperature and humidity environment that is more conducive to formaldehyde volatilization from that material.

[0050] 102. Based on the material type and the number of material types, the working mode that matches at least one identified material type is determined as the working mode of the indoor environmental conditioning system to increase the temperature and humidity of the indoor environment and exchange indoor and outdoor air, wherein different material types match different working modes, and the indoor humidity values ​​are different under different working modes.

[0051] Because different materials have different formaldehyde contents and volatilization rates, their optimal volatilization rates require different indoor temperature and humidity levels. This requires setting the operating mode of the indoor environmental conditioning system based on the different material types and the number of material types. Different operating modes are required for different material types or combinations of different material types to accelerate formaldehyde volatilization in homes. The impact of increased indoor temperature and humidity on materials must also be considered to comprehensively determine indoor temperature and humidity values ​​and indoor ventilation time to minimize the impact on the material's service life. In specific implementation, the material's deformation under different temperature and humidity environments can be used as a standard to increase the formaldehyde volatilization rate while keeping the material's deformation within an acceptable range. This requires setting the duration of the target indoor temperature and humidity environment and the ventilation time, thereby minimizing the material's deformation while promoting formaldehyde volatilization.

[0052] 103. If the number of material types is one, the operating mode of the environmental conditioning system is set to a working mode corresponding to the identified material type.

[0053] 104. If there are multiple types of materials, the operating mode of the environmental conditioning system is set to the operating mode that makes the indoor humidity value the lowest among the operating modes corresponding to the identified material types.

[0054] Considering that different materials have different formaldehyde volatilization rates and require different indoor temperature and humidity environments, the operating mode of the environmental conditioning system can be matched based on the number of materials present in the room. When a room contains only one material, the operating mode can be matched to the one corresponding to that material. However, when a room contains multiple materials, the operating mode selection needs to be adjusted accordingly. For example, the humidity values ​​in the operating modes for solid wood, solid wood composite, and laminated composite materials increase in sequence. If the operating mode for the material with the highest proportion is selected based on the proportion of each material, and a room contains solid wood and solid wood composite or laminated composite, with the solid wood composite or laminated composite having the highest proportion, and the operating mode corresponding to the solid wood composite or laminated composite is selected, the higher humidity value will cause irreversible damage to the solid wood materials in the room. Therefore, when a room contains more than one material, it is necessary to prioritize the more valuable materials and use the operating mode with the lowest humidity value to remove formaldehyde, thereby achieving rapid formaldehyde removal while protecting the materials.

[0055] 105. Control the environmental regulation system to operate in a certain working mode.

[0056] After determining the appropriate operating mode based on the type of indoor materials, the environmental conditioning system can be set to operate in this mode to remove indoor formaldehyde. Generally, after one year of continuous operation, all indoor formaldehyde is eliminated. The formaldehyde removal method provided by the present invention can accelerate the formaldehyde removal process by matching different operating modes to different material combinations, based on the varying amounts and rates of formaldehyde released. This prevents the natural release of odors that can take a long time before occupancy.

[0057] To further optimize this technical solution, refer to Figure 2 As shown, in another specific embodiment of the present invention, before determining the operating mode matching the at least one identified material type as the operating mode of the target indoor environment conditioning system based on the material type and the number of material types, the formaldehyde removal method may further include the following steps:

[0058] 201. Obtain indoor and outdoor temperature and humidity values, and adjust the opening and closing of windows in the target room and the opening and closing of the environmental conditioning system through the smart home system based on the obtained temperature and humidity values.

[0059] 202. If the obtained temperature and humidity values ​​meet the window opening conditions, the window is opened through the smart home system and the environmental conditioning system is turned off at the same time, where the window opening conditions include that the obtained temperature value is not lower than the first preset temperature value and the obtained humidity value is not lower than the minimum humidity value in the working mode.

[0060] 203. If the obtained temperature and humidity values ​​do not meet the window opening conditions, the smart home system closes the window and triggers the following steps: based on the material type and the number of material types, the working mode that matches at least one identified material type is determined as the working mode of the indoor environmental conditioning system.

[0061] Specifically, because home furnishings are mostly made of solid wood, solid wood composite, and laminated composite, the temperature required for formaldehyde volatilization in these materials is around 30°C and the humidity is around 80%, which is not a significant difference. However, the outdoor temperature and humidity levels can meet these conditions in both the south and north during summer. Therefore, when the outdoor temperature and humidity levels match the specified operating mode, the smart home system can open the windows for ventilation. If the outdoor conditions do not meet the specified operating mode, the windows are closed and the indoor climate control system is activated. This allows for more days in the summer when windows can be opened and for longer periods of time, effectively reducing energy consumption. Furthermore, on rainy days, the smart home system can promptly close windows to prevent rain from entering the home.

[0062] As a feasible implementation of the above embodiment, the determination of the operating time of the working mode is referred to Figure 3The following steps may be included:

[0063] 301. Determine the season of the indoor area based on the acquired temperature and humidity values.

[0064] The outdoor temperature and humidity values ​​can be acquired in real time through the temperature and humidity sensors installed outdoors, and the season of the current area can be determined based on the acquired temperature and humidity values. The specific judgment process can be combined with the smart home Internet network to obtain time, location and other information and combine with weather forecast data to determine the current season of the area.

[0065] 302. Determine the working hours of each working mode based on the current season.

[0066] 303. Continuously operate the corresponding working mode on the environmental conditioning system during working hours.

[0067] For example, if the current region is northern China and the season is determined to be autumn, the specified operating mode can be continuously operated during autumn and the following winter. When spring and summer arrive, the smart home system can flexibly adjust the operating time of each operating mode of the environmental control system based on the outdoor temperature and humidity values ​​by opening and closing windows and adjusting the operating time of each operating mode. For example, open windows for ventilation between 8:00 and 18:00 during the day, and run the corresponding operating mode of the environmental control system at other times.

[0068] Reference Figure 4 In some specific embodiments of the present invention, the process of identifying the material type of at least part of the indoor furniture may include the following steps:

[0069] 401. A near-infrared spectrometer is used to emit infrared waves of a preset wavelength into the room.

[0070] 402. Determine the type of material contained in the room based on the waveform of the infrared wave reflected back from the room.

[0071] Specifically, near-infrared spectroscopy is an indirect analysis technique that uses statistical methods to establish a correlation model between the sample's measured property values ​​and near-infrared spectral data. When a beam of infrared light with a continuous wavelength passes through a substance, and the vibrational frequency or rotational frequency of a group in the substance's molecules is the same as the frequency of the infrared light, the molecules absorb energy and transition from their original ground state vibrational (rotational) energy level to a higher energy vibrational (rotational) energy level. After the molecules absorb infrared radiation, vibrational and rotational energy level transitions occur, and light of that wavelength is absorbed by the substance. The absorption of infrared light by the molecules is recorded using a near-infrared spectrometer to obtain an infrared spectrum (waveform diagram). The type of material can then be determined using the pre-established correlation model.

[0072] In some other specific embodiments of the present invention, the environmental conditioning system may include an air conditioning system and a fresh air system. Based on the type of material and the number of material types, the operating mode is determined as follows:

[0073] The air conditioning system and the fresh air system are operated alternately within a preset time period, wherein the operating times of the air conditioning system and the fresh air system in different working modes are different, and the operating humidity values ​​of the air conditioning system are different.

[0074] Specifically, when the room contains only one type of material and the material type is solid wood, the working modes corresponding to solid wood include:

[0075] Each day is divided into three time periods on average, and each time period is divided into two operating cycles. The air-conditioning system is operated in the first operating cycle, and the fresh air system is operated in the second operating cycle. The air-conditioning system is operated at the second preset temperature value and the first preset humidity value, and the wind speed of the air-conditioning system and the fresh air system is the wind speed of the first preset gear.

[0076] When the interior contains only one type of material and the material type is solid wood composite, the working modes corresponding to solid wood composite include:

[0077] Each day is divided into two time periods on average, and each time period is divided into two operating cycles. The air-conditioning system is operated in the first operating cycle, and the fresh air system is operated in the second operating cycle. The air-conditioning system is operated at a second preset temperature value and a second preset humidity value. The wind speed of the air-conditioning system and the fresh air system is the wind speed of the first preset gear, and the second preset humidity value is greater than the first preset humidity value.

[0078] When the interior contains only one type of material and the material type is reinforced composite, the working modes corresponding to solid wood composite include:

[0079] Take each day as a time period, and divide the time period into two operating cycles. The air-conditioning system is operated in the first operating cycle, and the fresh air system is operated in the second operating cycle. The air-conditioning system uses the second preset temperature value and the third preset humidity value. The wind speed of the air-conditioning system and the fresh air system is the wind speed of the first preset gear, and the third preset humidity value is greater than the second preset humidity value.

[0080] For example, when the material type is solid wood, the corresponding working mode is: air conditioning operating temperature: 28℃; humidity 80%, the wind speed of the air conditioning system and the fresh air system are both at the middle speed. The daily operating time is:

[0081] Time period 1: The air conditioning system runs for 5 hours and the fresh air system runs for 3 hours.

[0082] Time period 2: The air conditioning system runs for 5 hours and the fresh air system runs for 3 hours.

[0083] Time period 3: The air conditioning system runs for 5 hours, and the fresh air system runs for 3 hours. The above cycle runs for 180 days.

[0084] When the material type is solid wood composite, the corresponding working mode is: air conditioning operating temperature: 30℃; humidity 85%, the wind speed of the air conditioning system and the fresh air system are both at the middle speed. The daily operating time is:

[0085] Time period 1: The air conditioning system runs for 7.5 hours and the fresh air system runs for 4.5 hours.

[0086] Time period 2: The air conditioning system runs for 7.5 hours, and the fresh air system runs for 4.5 hours, and operates in the above mode for 180 days.

[0087] When the material type is reinforced composite, the corresponding working mode is: air conditioning operating temperature: 30℃; humidity 90%, the wind speed of the air conditioning system and the fresh air system are both at the middle speed. The daily operating time is:

[0088] Time period 1: The air conditioning system runs for 15 hours and the fresh air system runs for 9 hours, and it runs in this mode for 180 days.

[0089] It is understandable that those skilled in the art can set the time periods, the operating cycles in each time period, and the corresponding temperature and humidity values ​​according to actual needs, and the present invention does not limit them here.

[0090] Based on the same design ideas Figure 5 As shown, an embodiment of the present invention further provides a formaldehyde removal device, which can perform each step of the formaldehyde removal method described in the above embodiment, and the device may include:

[0091] The material identification module 501 is used to identify the material type of at least part of the indoor furniture.

[0092] The working mode determination module 502 is used to determine the working mode that matches at least one identified material type as the working mode of the indoor environment conditioning system based on the material type and the number of material types, so as to increase the temperature and humidity of the indoor environment and exchange it with the outdoor air, wherein different material types match different working modes, and different working modes have different indoor humidity values.

[0093] If the number of material types is one, the operating mode of the environmental conditioning system is set to a working mode corresponding to the identified material type.

[0094] If there are multiple types of materials, the operating mode of the environmental conditioning system is set to the operating mode that makes the indoor humidity value the lowest among the operating modes corresponding to the identified material types.
