[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

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

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

[0039] like Figure 1 As shown in the figure, it is a schematic diagram of the air duct structure of the fresh air fan filtering outdoor air. The fresh air fan generates negative pressure through the rotation of the fan, and introduces the air in the outdoor environment into the air duct through the air inlet. After secondary filtration by the coarse-grained air filter element and the fine-grained air filter element in the air duct, it is discharged into the indoor environment through the air outlet. When the outdoor ambient temperature is low, the auxiliary heating device (such as Figure 1The auxiliary heating function of the heating resistor wire) is used to increase the temperature of the air entering the indoor environment.

[0040] The above-mentioned coarse-grained air filter element is used to filter particles with a diameter of 4μm (micrometers) or more in the air, such as pollen, dust, flying insects, etc.; the above-mentioned fine-grained air filter element is used to filter dust particles PM0.3 and above in the air to reduce the number of harmful bacteria in the air.

[0041] In the control method of indoor and outdoor air exchange in the related art, it is usually entirely up to the user to decide when to perform the ventilation operation, or to perform the ventilation operation when the indoor environmental parameters (for example, carbon dioxide concentration) exceed the preset threshold value. The degree of intelligence is low, which causes a waste of power resources to a certain extent. In addition, since there is only one air duct, when the related equipment performs the ventilation operation, all the air will be filtered twice before being delivered to the room, which reduces the service life of the fine-grained air filter element (compared with the coarse-grained air filter element, the cost is higher) to a certain extent, and increases the user's use cost.

[0042] In response to the above-mentioned technical problems existing in the related technology, the embodiment of the present application provides a control method for indoor and outdoor air exchange, which can improve the resource utilization of ventilation equipment through an intelligent control method, and to a certain extent increase the service life of the filter element, thereby reducing the user's usage cost.

[0043] The control method for indoor and outdoor air exchange provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

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

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

[0046] Exemplarily, the target pollutants may include any of the following: PM2.5, PM10, floating sediment, carbon dioxide CO2, etc. In addition to the above pollutants, the target pollutants may also include other pollutants that can reflect the quality of the outdoor environment.

[0047] Exemplarily, the first pollutant concentration value of the target pollutant in the outdoor environment can be obtained by an environmental sensor that can contact the outdoor environment. The environmental sensor can be set on an outdoor wall or at the air inlet of the electronic device.

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

[0049] Among them, the target control method includes any one of the following: a first control method for controlling the ventilation operation of the electronic device based on a first filtering method, and a second control method for controlling the ventilation operation of the electronic device based on a second filtering method; the first filtering method includes: performing coarse-grained filtering and fine-grained filtering on outdoor air at the same time; the second filtering method includes: performing only coarse-grained filtering on outdoor air.

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

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

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

[0053] Step 202a: when the first pollutant concentration value is greater than or equal to the target pollutant concentration value, determine the first control mode as the target control mode.

[0054] Step 202b: when the first pollutant concentration value is less than the target pollutant concentration value, determine the second control mode as the target control mode.

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

[0056] It can be understood that when the first pollutant concentration value is greater than or equal to the target pollutant concentration value, it indicates that the outdoor environment quality is poor. At this time, if ventilation operation is to be performed, the air entering the indoor environment must be filtered at the same time through coarse-grained filtration and fine-grained filtration through secondary filtration; when the first pollutant concentration value is less than the target pollutant concentration value, it indicates that the outdoor environment quality is good. At this time, if ventilation operation is to be performed, the air entering the indoor environment can be filtered at the coarse-grained level without fine-grained filtration, thereby increasing the service life of the coarse-grained air filter element.

[0057] In a possible implementation, before the above step 202a, the control method for indoor and outdoor air exchange provided in the embodiment of the present application may further include the following steps 204 and 205:

[0058] Step 204: Based on the current date, obtain the average historical pollutant concentration corresponding to the current month in the area where the electronic device is located.

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

[0060] For example, the above target pollutant concentration value is not a fixed parameter value, but is determined according to the average historical pollutant concentration value corresponding to the current month. For example, taking June as an example, the average historical pollutant concentration value of the current month can be the average pollutant concentration value of 30 days in June last year.

[0061] Exemplarily, for the calculation of the above-mentioned target pollutant concentration value, assuming that the average historical pollutant concentration value of the current month is 64, the preset pollutant concentration value of the electronic device is 120, and the preset pollutant concentration average value corresponding to the 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 an embodiment of the present application, the electronic device can set a corresponding preset pollutant concentration value (for example, 120) according to the average pollutant concentration value of each city (for example, 90). When it is detected that the pollutant concentration value of the outdoor environment is greater than the preset pollutant concentration value, it can be judged that the air quality of the outdoor environment is poor. However, due to the large differences in environmental quality in various regions, the preset pollutant concentration value can be adjusted according to the average historical pollutant concentration value of 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 value of the month is 40), the preset pollutant concentration value can be appropriately lowered to avoid the electronic device always controlling the ventilation operation according to the second control mode.

[0063] In a possible implementation, in order to enable the electronic device to filter the air entering the room according to different filtering methods, the embodiment of the present application provides an improvement on the air duct of the electronic device.

[0064] Exemplarily, the electronic device includes: a first air duct and a second air duct; the first air duct includes: a coarse-grained air filter and a fine-grained air filter; the second air duct includes: a coarse-grained air filter; the coarse-grained air filter is used to perform coarse-grained filtering on outdoor air; the fine-grained air filter is used to perform fine-grained filtering on outdoor air; the electronic device switches between the first air duct and the second air duct through an air duct switching device.

[0065] For example, Figure 3 As shown, it is a schematic diagram of an improved air duct structure provided by an embodiment of the present application. It includes air duct 1 (i.e. the above-mentioned first air duct) and air duct 2 (i.e. the above-mentioned second air duct). When the outdoor air quality is poor, the outdoor air can be filtered twice through air duct 1, that is, the outdoor air is first filtered once through a coarse-grained air filter element, and then filtered twice through a fine-grained air filter element; when the outdoor air quality is good, the outdoor air can be filtered once through air duct 1, that is, the outdoor air is filtered once through a coarse-grained air filter element, and then it is directly transported to the room.

[0066] It should be noted that the control method for indoor and outdoor air exchange provided in the embodiment of the present application, in addition to the automatic control function, also provides a manual control function. The user can force the electronic device to perform ventilation operations through manual control, and the user can also select the air duct.

[0067] Optionally, in the embodiment of the present application, based on the above step 202a, the above step 203 may further include the following steps 203a1 to 203a3:

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

[0069] Step 203a2: When the outdoor ambient temperature is greater than or equal to the indoor ambient temperature, the ventilation operation is not performed, or the ventilation operation being performed is stopped.

[0070] Step 203a3: when the outdoor ambient temperature is lower than the indoor ambient temperature, a target difference between the first pollutant concentration value and the second pollutant concentration value is calculated; if the target difference is lower than a preset concentration threshold, a ventilation operation is performed based on the first filtering mode, and an auxiliary heating function is turned on; otherwise, a ventilation operation is not performed, or the ventilation operation being performed is stopped;

[0071] Among them, the heating power of the auxiliary heating function is positively correlated with the temperature difference between the indoor and outdoor environments; the fan speed when performing the ventilation operation is negatively correlated with the temperature difference between the indoor and outdoor environments.

[0072] For example, in order to avoid a large difference in temperature between the outdoor air input into the room and the ambient temperature of the indoor environment, the heating power may be increased and / or the fan speed may be reduced when the temperature difference is large.

[0073] It is understandable that when the air quality of the outdoor environment is poor, the electronic device will control the ventilation operation according to the first control mode. At this time, the electronic device needs to determine whether the outdoor environment temperature is greater than or equal to the indoor environment temperature.

[0074] When the outdoor ambient temperature is greater than or equal to the indoor ambient temperature, delivering outdoor air indoors will not only increase the indoor ambient temperature and affect the user's comfort, but will also greatly reduce the service life of the filter element. At this time, the electronic device will not perform ventilation operations; when the outdoor ambient temperature is lower than the indoor ambient temperature, ventilation operations can be performed to heat the outdoor air and deliver it to the indoor environment. Whether to perform ventilation operations also needs to be combined with the target difference between indoor and outdoor environmental pollutants. When the target difference is less than the preset concentration threshold, it means that the air quality of the outdoor environment is poor, but the air quality of the indoor environment is also poor. At this time, ventilation operations can be performed; when the target difference is greater than or equal to the preset concentration threshold, it means that the air quality of the outdoor environment is poor, but the air quality of the indoor environment is good. The ventilation operation can be omitted. Wait until the air quality of the outdoor environment improves before performing ventilation operations to avoid the poor outdoor air significantly reducing the service life of the filter element.

[0075] Optionally, in the embodiment of the present application, based on the above step 202b, the above step 203 may further include the following steps 203b1 to 203b3:

[0076] Step 203b1, obtaining the outdoor environment temperature, the indoor environment temperature and the second pollutant concentration value 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 filtering method; otherwise, do not perform a ventilation operation, or stop the ventilation operation being performed.

[0078] Step 203b3: When the outdoor ambient temperature is lower than the indoor ambient temperature, if the target difference is lower than the preset concentration threshold, ventilation operation is performed based on the first filtering method, and the auxiliary heating function is turned on; otherwise, ventilation operation is not performed, or the ventilation operation being performed is stopped.

[0079] Among them, the heating power of the auxiliary heating function is positively correlated with the temperature difference between the indoor and outdoor environments; the fan speed when performing the ventilation operation is negatively correlated with the temperature difference between the indoor and outdoor environments.

[0080] It is understandable that when the air quality of the outdoor environment is good, the electronic device will control the ventilation operation according to the second control mode. At this time, the electronic device needs to determine whether the outdoor environment temperature is greater than or equal to the indoor environment temperature.

[0081] When the outdoor ambient temperature is greater than or equal to the indoor ambient temperature, although delivering outdoor air to the indoor environment will increase the indoor ambient temperature and affect the user's comfort, it will have little impact on the service life of the filter element and will not affect the service life of the fine-grained air filter element. At this time, the electronic device can perform a ventilation operation; when the outdoor ambient temperature is lower than the indoor ambient temperature, a ventilation operation can also be performed to heat the outdoor air and deliver it to the indoor environment. Whether to perform a ventilation operation also needs to be combined with the target difference between indoor and outdoor environmental pollutants. When the target difference is less than the preset concentration threshold, it means that the air quality of the outdoor environment is poor, but the air quality of the indoor environment is also poor (relatively poor). At this time, a ventilation operation can be performed; when the target difference is greater than or equal to the preset concentration threshold, it means that the air quality of the outdoor environment is poor, but the air quality of the indoor environment is good. The ventilation operation can be omitted. Wait until the air quality of the outdoor environment improves before performing the ventilation operation to avoid the poor outdoor air significantly reducing the service life of the filter element.

[0082] It should be noted that both the first air duct and the second air duct need to filter the air through a coarse-grained air filter to prevent floating objects such as mosquitoes, catkins, and poplar catkins in the outdoor environment from entering the indoor environment and affecting the user.

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

[0084] Step 203c 1. When it is determined that the target control mode of the electronic device is 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 it is determined that the target control mode of the electronic device is 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 optionally, based on Figure 3 For the air duct design shown, the corresponding filter element life calculation method can be used to calculate the remaining life of the filter element.

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

[0088] Step 206: When the air duct of the electronic device is the first air duct, the service life of the coarse-grained air filter element and the fine-grained air filter element is calculated according to 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: When the air duct of the electronic device is the second air duct, the service life of the coarse-grained air filter is calculated according to 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.
