[0002] As people's living standards continue to improve and the level of intelligence in home appliances continues to rise, smart home appliances are becoming increasingly popular.

[0003] In related technologies, taking fresh air systems as an example, when users notice that the indoor air is polluted or has an odor, they can control the fresh air system to perform ventilation.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] It should be noted that the control method for indoor and outdoor air exchange provided in this application embodiment can be applied to electronic devices with ventilation functions such as air conditioners and fresh air units.

[0038] The following is a detailed description of the operating principle of the air conditioner or fresh air unit with ventilation function involved in the embodiments of this application:

[0039] like Figure 1 The diagram shows the duct structure of a fresh air system for filtering outdoor air. The system generates negative pressure through fan rotation, drawing outdoor air into the duct through the inlet. After secondary filtration through coarse and fine particle air filters within the duct, the air is discharged into the indoor environment through the outlet. When the outdoor temperature is low, an auxiliary heating device (such as...) can also be activated. Figure 1The auxiliary heating function of the heating resistance wire shown is used to increase the temperature of the air entering the indoor environment.

[0040] The aforementioned coarse-particle air filter is used to filter particulate matter with a diameter of 4μm (micrometers) or larger in the air, such as pollen, dust, and flying insects; the aforementioned fine-particle air filter is used to filter dust particles of PM0.3 and larger in the air, in order to reduce the number of harmful bacteria in the air.

[0041] The control methods for indoor and outdoor air exchange in related technologies are usually entirely user-defined, with ventilation operations triggered only when indoor environmental parameters (e.g., carbon dioxide concentration) exceed a preset threshold. This lack of automation leads to a certain degree of energy waste. Furthermore, because there is only one air duct, all air undergoes secondary filtration before being delivered indoors, reducing the lifespan of fine-particle air filters (which are more expensive than coarse-particle filters) and increasing user costs.

[0042] In view of the above-mentioned technical problems in related technologies, this application provides a control method for indoor and outdoor air exchange, which can improve the resource utilization rate of ventilation equipment and, to a certain extent, extend the service life of filter elements and reduce user costs through intelligent control.

[0043] The control method for indoor and outdoor air exchange provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0044] like Figure 2 As shown in the embodiment of this application, a control method for indoor and outdoor air exchange is provided, which may include the following steps 201 to 204:

[0045] Step 201: Obtain the first pollutant concentration value of the target pollutant in the outdoor environment.

[0046] For example, the target pollutants may include any of the following: PM2.5, PM10, particulate matter, carbon dioxide (CO2), etc. In addition to the above-mentioned pollutants, the target pollutants may also include other pollutants that can reflect outdoor environmental quality.

[0047] For example, the first pollutant concentration value of the target pollutant in the outdoor environment can be obtained by an environmental sensor that can access the outdoor environment. This environmental sensor can be installed on an outdoor wall or at the air inlet of an electronic device.

[0048] Step 202: Determine the target control mode of the electronic device based on the comparison result between the first pollutant concentration value and the target pollutant concentration value.

[0049] The target control method includes any one of the following: a first control method that controls the ventilation operation of the electronic device based on a first filtration method, and a second control method that controls the ventilation operation of the electronic device based on a second filtration method; the first filtration method includes: simultaneously performing coarse-particle filtration and fine-particle filtration on outdoor air; the second filtration method includes: performing only coarse-particle filtration on outdoor air.

[0050] Step 203: Control the ventilation operation of the electronic device according to the target control method.

[0051] For example, after determining the control method of the electronic device, the ventilation operation of the electronic device can be controlled based on the control method.

[0052] Specifically, step 202 above may include either step 202a or step 202b:

[0053] Step 202a: If the concentration value of the first pollutant is greater than or equal to the concentration value of the target pollutant, the first control method is determined as the target control method.

[0054] Step 202b: If the concentration value of the first pollutant is less than the concentration value of the target pollutant, the second control method is determined as the target control method.

[0055] For example, when the concentration of the first pollutant is greater than or equal to the concentration of the target pollutant, the electronic device can control its ventilation operation based on a first filtration method that simultaneously performs coarse-grained filtration and fine-grained filtration on the outdoor air; conversely, when the concentration of the first pollutant is less than the concentration of the target pollutant, the electronic device can control its ventilation operation based on a second filtration method that only performs coarse-grained filtration on the outdoor air.

[0056] Understandably, when the concentration of the first pollutant is greater than or equal to the concentration of the target pollutant, it indicates that the outdoor environmental quality is poor. In this case, if ventilation is to be performed, the air entering the indoor environment must be filtered through a secondary filtration process, using both coarse and fine particles. When the concentration of the first pollutant is less than the concentration of the target pollutant, it indicates that the outdoor environmental quality is good. In this case, if ventilation is to be performed, the air entering the indoor environment can be filtered through coarse particles without the need for fine particle filtration, thereby extending the lifespan of the coarse particle air filter.

[0057] In one possible implementation, prior to step 202a above, the control method for indoor and outdoor air exchange provided in this application embodiment may further include steps 204 and 205:

[0058] Step 204: Obtain the average historical pollutant concentration for the current month in the region where the electronic device is located, based on the current date.

[0059] Step 205: Based on the ratio of the historical average pollutant concentration to the preset average pollutant concentration corresponding to the preset pollutant concentration value, adjust the preset pollutant concentration value to obtain the target pollutant concentration value.

[0060] For example, the target pollutant concentration value mentioned above is not a fixed parameter value, but is determined based on the historical average pollutant concentration value corresponding to the current month. For instance, taking the current month as June, the historical average pollutant concentration value for the current month could be the average pollutant concentration value for the 30 days of June last year.

[0061] For example, regarding the calculation of the target pollutant concentration value, assuming that the historical average pollutant concentration for the current month is 64, the preset pollutant concentration value of the electronic device is 120, and the preset average pollutant concentration corresponding to this preset pollutant concentration value is 90, then the target pollutant concentration value is: 64 / 90*120=85.33.

[0062] It should be noted that, in this embodiment, the electronic device can set a corresponding preset pollutant concentration value (e.g., 120) based on the average pollutant concentration of each city (e.g., 90). When the detected outdoor pollutant concentration value is greater than the preset pollutant concentration value, it can be determined that the outdoor air quality is poor. However, since there are significant differences in environmental quality across regions, the preset pollutant concentration value can be adjusted based on the average historical pollutant concentration of the current month in the current region. For example, if the air quality in the area where the electronic device is located is good (the average historical pollutant concentration for the current month is 40), the preset pollutant concentration value can be appropriately reduced to avoid the electronic device always controlling the ventilation operation according to the second control method.

[0063] In one possible implementation, in order to enable electronic devices to filter incoming indoor air according to different filtration methods, embodiments of this application propose to improve the air duct of the electronic devices.

[0064] For example, the electronic device includes: a first air duct and a second air duct; the first air duct includes: a coarse-particle air filter and a fine-particle air filter; the second air duct includes: a coarse-particle air filter; the coarse-particle air filter is used to perform coarse-particle filtration of outdoor air; the fine-particle air filter is used to perform fine-particle filtration of outdoor air; the electronic device switches between the first air duct and the second air duct via an air duct switching device.

[0065] For example, such as Figure 3 The diagram shown is a schematic representation of an improved air duct structure provided in an embodiment of this application. It includes air duct 1 (i.e., the aforementioned first air duct) and air duct 2 (i.e., the aforementioned second air duct). When the outdoor air quality is poor, outdoor air undergoes secondary filtration through air duct 1, meaning it first passes through a coarse-particle air filter for primary filtration, and then through a fine-particle air filter for secondary filtration. When the outdoor air quality is good, outdoor air undergoes primary filtration through air duct 1, meaning that after passing through the coarse-particle air filter, the outdoor air is directly delivered indoors.

[0066] It should be noted that the control method for indoor and outdoor air exchange provided in this application embodiment, in addition to the automatic control function, also provides a manual control function. Users can manually control the electronic equipment to perform the air exchange operation, and users can also select the air duct.

[0067] Optionally, in this embodiment of the application, based on the above steps 202a and 203, the following steps 203a1 to 203a3 may also be included:

[0068] Step 203a1: Obtain the outdoor ambient temperature, the indoor ambient temperature, and the concentration of the second pollutant of the target pollutant in the indoor environment.

[0069] Step 203a2: If the outdoor ambient temperature is greater than or equal to the indoor ambient temperature, do not perform the ventilation operation, or stop the ventilation operation that is being performed.

[0070] Step 203a3: When the outdoor ambient temperature is lower than the indoor ambient temperature, calculate the target difference between the first pollutant concentration value and the second pollutant concentration value. If the target difference is less than a preset concentration threshold, perform a ventilation operation based on the first filtration method and turn on the auxiliary heating function; otherwise, do not perform a ventilation operation, or stop the ventilation operation that is being performed.

[0071] The heating power of the auxiliary heating function is positively correlated with the temperature difference between the indoor and outdoor environments; the fan speed during ventilation is negatively correlated with the temperature difference between the indoor and outdoor environments.

[0072] For example, to avoid a large temperature difference between the outdoor air entering the room and the indoor environment, the heating power can be increased and / or the fan speed can be reduced when the temperature difference is large.

[0073] Understandably, when outdoor air quality is poor, electronic devices will control ventilation according to the first control method. At this time, the electronic devices need to determine whether the outdoor ambient temperature is greater than or equal to the indoor ambient temperature.

[0074] When the outdoor temperature is greater than or equal to the indoor temperature, supplying outdoor air indoors will not only raise the indoor temperature, affecting user comfort, but also significantly reduce the lifespan of the filter. In this case, the electronic device will not perform ventilation. When the outdoor temperature is lower than the indoor temperature, ventilation can be performed, heating the outdoor air before supplying it indoors. Whether to perform ventilation also depends on the target difference in pollutants between indoor and outdoor environments. When the target difference is less than a preset concentration threshold, it indicates that both outdoor and indoor air quality are poor; in this case, ventilation can be performed. When the target difference is greater than or equal to the preset concentration threshold, it indicates that both outdoor and indoor air quality are poor; in this case, ventilation can be delayed until outdoor air quality improves to avoid significantly reducing the filter's lifespan due to poor outdoor air quality.

[0075] Optionally, in this embodiment of the application, based on the above steps 202b and 203, the following steps 203b1 to 203b3 may also be included:

[0076] Step 203b1: Obtain the outdoor ambient temperature, the indoor ambient temperature, and the concentration of the second pollutant of the target pollutant in the indoor environment.

[0077] Step 203b2: When the outdoor ambient temperature is greater than or equal to the indoor ambient temperature, calculate the target difference between the first pollutant concentration value and the second pollutant concentration value. If the target difference is less than a preset concentration threshold, perform a ventilation operation based on the second filtration method; otherwise, do not perform a ventilation operation, or stop the ventilation operation that is being performed.

[0078] Step 203b3: If the target difference is less than a preset concentration threshold when the outdoor ambient temperature is lower than the indoor ambient temperature, then an air exchange operation is performed based on the first filtration method, and the auxiliary heating function is turned on; otherwise, the air exchange operation is not performed, or the air exchange operation being performed is stopped.

[0079] The heating power of the auxiliary heating function is positively correlated with the temperature difference between the indoor and outdoor environments; the fan speed during ventilation is negatively correlated with the temperature difference between the indoor and outdoor environments.

[0080] Understandably, when the outdoor air quality is good, the electronic equipment will control the ventilation operation according to the second control method. At this time, the electronic equipment needs to determine whether the outdoor ambient temperature is greater than or equal to the indoor ambient temperature.

[0081] When the outdoor temperature is greater than or equal to the indoor temperature, supplying outdoor air into the room will raise the indoor temperature and affect user comfort, but it has little impact on the lifespan of the filter element and will not affect the lifespan of the fine-particle air filter. In this case, the electronic device can perform a ventilation operation. When the outdoor temperature is lower than the indoor temperature, a ventilation operation can also be performed, heating the outdoor air before supplying it into the indoor environment. Whether to perform a ventilation operation also needs to be considered in conjunction with the target difference of pollutants in the indoor and outdoor environments. When the target difference is less than the preset concentration threshold, it indicates that the outdoor air quality is poor, but the indoor air quality is also relatively poor. In this case, a ventilation operation can be performed. When the target difference is greater than or equal to the preset concentration threshold, it indicates that the outdoor air quality is poor, but the indoor air quality is good. In this case, a ventilation operation can be delayed until the outdoor air quality improves, in order to avoid the poor outdoor air significantly reducing the lifespan of the filter element.

[0082] It should be noted that both the first and second air ducts require air filtration through coarse-grained air filters to prevent outdoor pollutants such as mosquitoes, willow catkins, and poplar fluff from entering the indoor environment and affecting users.

[0083] Optionally, in embodiments of this application, based on such Figure 3 As shown in the structural diagram, step 203 above may further include the following steps: 203c1 or 203c2.

[0084] Step 203c 1. When the target control mode of the electronic device is determined to be the first control mode, control the air duct switching device to switch the air duct of the electronic device to the first air duct.

[0085] Step 203c 2: When the target control mode of the electronic device is determined to be the second control mode, control the air duct switching device to switch the air duct of the electronic device to the second air duct.

[0086] Further, alternatively, based on such Figure 3 The air duct design shown can be used to calculate the remaining life of the filter element using the corresponding filter element life calculation method.

[0087] For example, after step 203 above, the control method for indoor and outdoor air exchange provided in this application embodiment may further include step 206 or step 207:

[0088] Step 206: If the air duct of the electronic device is the first air duct, calculate the service life of the coarse-particle air filter and the fine-particle air filter based on the difference between the pollutant concentration at the air inlet of the first air duct and the pollutant concentration at the air outlet of the first air duct.

[0089] Step 207: If the air duct of the electronic device is the second air duct, calculate the service life of the coarse-grained air filter element based on the difference between the pollutant concentration at the air inlet of the second air duct and the pollutant concentration at the air outlet of the second air duct.

[0090] It is understandable that when outdoor air enters the room through the first air duct, both the coarse-particle air filter and the fine-particle air filter will have their lifespans consumed; when outdoor air enters the room through the second air duct, only the coarse-particle air filter will have its lifespan consumed. The specific method for calculating filter lifespan can be found in related technologies, and will not be elaborated upon in this embodiment.

[0091] It should be noted that the control method for indoor and outdoor air exchange provided in this application embodiment can be executed by an air conditioner with ventilation function, a fresh air unit, or other electronic devices with ventilation function.

[0092] The control method for indoor and outdoor air exchange provided in this application first obtains a first pollutant concentration value in the outdoor environment; then, based on a comparison between the first pollutant concentration value and a target pollutant concentration value, a target control mode for the electronic device is determined; and the ventilation operation of the electronic device is controlled according to the target control mode. The target control mode includes any one of the following: a first control mode based on a first filtration mode, and a second control mode based on a second filtration mode; the first filtration mode includes simultaneously performing coarse-particle filtration and fine-particle filtration on the outdoor air; the second filtration mode includes performing only coarse-particle filtration on the outdoor air.
