[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description relating to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements.

[0025] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0026] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0027] Smart air conditioners can sense the indoor ambient temperature and then send it to the user's device for display. On the one hand, this improves the user's visibility and allows for more personalized temperature adjustments. On the other hand, it provides accurate information about the indoor temperature when the user is not at home, allowing them to turn on the air conditioner in advance and adjust the temperature to a comfortable level before returning home, thus enhancing their comfort.

[0028] In related technologies, regarding air conditioning cooling, due to the influence of cold radiation from the evaporator of the indoor unit of the air conditioner, there is a certain deviation between the temperature measured by the inner ring temperature sensor and the actual indoor ambient temperature, resulting in a large difference between the indoor ambient temperature displayed by the air conditioner and the actual indoor ambient temperature received by the user.

[0029] To address the aforementioned technical problems, this disclosure provides a method, apparatus, and electronic device for determining indoor ambient temperature. This method can determine the indoor ambient temperature of a target air conditioner under different cooling states and corresponding state parameters based on at least one of a first temperature corresponding to the upper end of the return air vent, a second temperature corresponding to the lower end of the return air vent, and the internal pipe temperature of the target air conditioner. This allows for the selection of different temperature determination methods based on the cooling state and corresponding state parameters of the target air conditioner to obtain the indoor ambient temperature, thereby improving the accuracy of the obtained indoor ambient temperature.

[0030] Figure 1 This is a schematic diagram illustrating an application scenario of an indoor ambient temperature determination method according to an exemplary embodiment, such as... Figure 1 As shown, users can perform intelligent control actions on the air conditioner through the smart control APP on the smart terminal. The air conditioner can send the indoor ambient temperature of the determined area to the smart control APP (Application) so that users can obtain the indoor ambient temperature of the area where the air conditioner is located in real time and then perform corresponding control actions.

[0031] Figure 2 This is a flowchart illustrating a method for determining indoor ambient temperature according to an exemplary embodiment, such as... Figure 2 As shown, this method can be applied to air conditioners and may include the following steps.

[0032] In step S201, the first temperature corresponding to the upper end of the return air vent of the target air conditioner and the second temperature corresponding to the lower end of the return air vent are obtained.

[0033] In this embodiment, the target air conditioner can be a vertical air conditioner. A first sensor can be installed at the upper end of the return air vent of the target air conditioner to obtain a first temperature corresponding to the upper end of the return air vent, and a second sensor can be installed at the lower end of the return air vent to obtain a second temperature corresponding to the lower end of the return air vent. Both the first and second sensors can be sensors with temperature detection functions; for example, the first sensor can be a temperature and humidity sensor, and the second sensor can be an inner-ring temperature sensing bulb.

[0034] In step S202, the indoor ambient temperature of the area where the target air conditioner is located is determined based on at least one of the first temperature, the second temperature, and the inner pipe temperature of the target air conditioner, as well as the cooling state of the target air conditioner and the state parameters corresponding to the cooling state.

[0035] In this embodiment, the indoor ambient temperature of the area where the target air conditioner is located can be determined based on different cooling states of the target air conditioner and their corresponding state parameters, combined with at least one of a first temperature, a second temperature, and the internal pipe temperature of the target air conditioner. This allows for the selection of different temperature determination methods to obtain the indoor ambient temperature based on the cooling state and corresponding state parameters of the target air conditioner, thereby improving the accuracy of the obtained indoor ambient temperature. The cooling state can be either cooling on or cooling off, and the corresponding state parameters can be the fan speed range of the target air conditioner or the duration of cooling off.

[0036] In one possible implementation, after obtaining the indoor ambient temperature of the area where the target air conditioner is located, the indoor ambient temperature of the area where the target air conditioner is located can be displayed to the user. Specifically, the indoor ambient temperature can be displayed to the user through the display interface on the target air conditioner, or the target air conditioner can send the indoor ambient temperature of the area where the target air conditioner is located to the smart control APP on the user's terminal, so that the user can obtain the indoor ambient temperature of the area where the air conditioner is located in real time.

[0037] In one possible implementation, when the cooling state is in the cooling-on state, the state parameters corresponding to the cooling state include the fan speed range of the target air conditioner.

[0038] Based on at least one of the first temperature, the second temperature, and the internal pipe temperature of the target air conditioner, as well as the cooling state of the target air conditioner and the corresponding state parameters, determine the indoor ambient temperature of the area where the target air conditioner is located, including: When the cooling mode is on and the fan speed is in the first fan speed range, the indoor ambient temperature of the area where the target air conditioner is located is determined based on the first temperature and the second temperature. When the cooling mode is on and the fan speed is in the second fan speed range, the first temperature is determined as the indoor ambient temperature of the area where the target air conditioner is located.

[0039] In this embodiment, the target air conditioner's cooling state can be in a cooling-on state. In this case, the state parameter corresponding to the cooling state can include the fan speed range of the target air conditioner. The fan speed range can be one of a first fan speed range and a second fan speed range. The airflow corresponding to the first fan speed range is greater than the airflow corresponding to the second fan speed range.

[0040] When the cooling mode is on and the fan speed is in the first fan speed range, the first and second temperatures are simultaneously affected by indoor temperature stratification and cold radiation during evaporation. The indoor ambient temperature of the target air conditioner can be determined by combining the difference between the first and second temperatures.

[0041] When the cooling mode is on and the fan speed is in the second setting, the temperature stratification between the upper and lower parts is more severe, and the hot air rises. However, the cooling capacity of the evaporator also has a greater impact on the first temperature. The two cancel each other out, making the first temperature closer to the average indoor temperature. The first temperature can be directly determined as the indoor ambient temperature of the area where the target air conditioner is located.

[0042] In one possible implementation, determining the indoor ambient temperature of the area where the target air conditioner is located, based on a first temperature and a second temperature, includes: If the difference between the first temperature and the second temperature is less than or equal to the first temperature threshold, the average of the first temperature and the second temperature is determined as the indoor ambient temperature of the area where the target air conditioner is located; if the temperature difference obtained by subtracting the second temperature from the first temperature is greater than the first temperature threshold, the first temperature is determined as the indoor ambient temperature of the area where the target air conditioner is located.

[0043] In this embodiment, when the difference between the first temperature and the second temperature is less than or equal to the first temperature threshold, due to the larger air volume, the indoor temperature distribution is more uniform, and the indoor air heat exchange is stronger, the impact of the cooling capacity during evaporation is smaller. Therefore, the difference between the first temperature and the second temperature is smaller, and the average of the first temperature and the second temperature can be determined as the indoor ambient temperature of the area where the target air conditioner is located, so as to obtain a more accurate indoor ambient temperature. The first temperature threshold can be 2℃.

[0044] If the temperature difference between the first temperature and the second temperature is greater than the first temperature threshold, it may be because the room is too large or too high, resulting in insufficient heat exchange and temperature stratification, which makes the difference between the first temperature and the second temperature too large. In this case, for a floor-standing air conditioner, since the height of the area corresponding to the first temperature is closer to the height of a human body, the first temperature can be directly determined as the indoor ambient temperature of the area where the target air conditioner is located.

[0045] In one possible implementation, if the temperature difference obtained by subtracting the first temperature from the second temperature is greater than the first temperature threshold, it is confirmed that either the first sensor that detected the first temperature or the second sensor that detected the second temperature has malfunctioned. The first sensor and the second sensor can be tested. If the first sensor is determined to be malfunctioning, the second temperature is determined to be the indoor ambient temperature of the area where the target air conditioner is located. If the second sensor is determined to be malfunctioning, the first temperature is determined to be the indoor ambient temperature of the area where the target air conditioner is located.

[0046] In one possible implementation, the method further includes: When the cooling mode is active and the fan speed is in the second setting range, the difference between the first and second temperatures can be determined. If this difference exceeds a second temperature threshold, the angle of the air deflector on the target air conditioner can be adjusted to enhance heat exchange within the room, resulting in a more uniform temperature distribution and thus reducing the temperature difference. The second temperature threshold can be the same as the first temperature threshold. Specifically, the air deflector of the target air conditioner can be adjusted to reciprocate within a target angle range, where the air conditioner is tilted upwards to output cool air. This reciprocating motion allows the cool air to be output upwards at different angles, enhancing heat exchange in different areas of the room, resulting in a more uniform temperature distribution and reducing the temperature difference. For example, with the air deflector tilted upwards as the positive direction, the target angle range can be +30° to +60°.

[0047] In one possible implementation, the method for determining the fan speed range of the target air conditioner can be: Obtain the fan speed value of the target air conditioner; if the fan speed value is greater than or equal to the preset fan speed value, determine the fan speed range of the target air conditioner as the first fan speed range; if the fan speed value is less than the preset fan speed value, determine the fan speed range of the target air conditioner as the second fan speed range.

[0048] In this embodiment, the fan speed range of the target air conditioner can be determined by the fan speed value. Specifically, the fan speed value is positively correlated with the air volume, and a first fan speed range and a second fan speed range can be distinguished by setting a preset fan speed value. When the fan speed value is greater than or equal to the preset fan speed value, the target air conditioner is determined to belong to the first fan speed range with a larger air volume; when the fan speed value is less than the preset fan speed value, the target air conditioner is determined to belong to the second fan speed range with a smaller air volume.

[0049] In one possible implementation, the method for determining the fan speed range of the target air conditioner can be: Obtain the indoor fan speed of the target air conditioner; if the indoor fan speed is greater than or equal to the preset speed, determine the fan speed range of the target air conditioner as the first fan speed range; if the indoor fan speed is less than the preset speed, determine the fan speed range of the target air conditioner as the second fan speed range.

[0050] In this embodiment, the fan speed of the target air conditioner can be determined by the speed of the indoor fan. Specifically, the indoor fan speed is positively correlated with the air volume, and a first fan speed range and a second fan speed range can be distinguished by setting a preset speed. When the indoor fan speed is greater than or equal to the preset speed, the target air conditioner is determined to belong to the first fan speed range with a larger air volume; when the indoor fan speed is less than the preset speed, the target air conditioner is determined to belong to the second fan speed range with a smaller air volume.

[0051] In one possible implementation, when the cooling state is the cooling off state, the state parameter corresponding to the cooling state includes the cooling off duration.

[0052] Based on at least one of the first temperature, the second temperature, and the internal pipe temperature of the target air conditioner, as well as the cooling state of the target air conditioner and the corresponding state parameters, determine the indoor ambient temperature of the area where the target air conditioner is located, including: When the cooling state is off and the cooling off time is less than or equal to the preset time, the historical indoor ambient temperature corresponding to the target time before the cooling stops is determined as the indoor ambient temperature of the area where the target air conditioner is located; when the cooling state is off and the cooling off time is longer than the preset time, the indoor ambient temperature of the area where the target air conditioner is located is determined based on the first temperature, the second temperature and the inner pipe temperature.

[0053] In this embodiment, the target air conditioner can be in a cooling off state, meaning that the indoor ambient temperature can be accurately obtained even after cooling is turned off. In this case, since the indoor unit evaporator has different degrees of influence on the first and second temperatures at different times, the state parameter corresponding to the cooling state may include the cooling off duration.

[0054] When the cooling mode is off and the cooling off time is less than or equal to the preset time, the indoor unit's evaporator rapidly heats up due to the compressor stopping, absorbing ambient heat and significantly affecting the first and second temperatures. Therefore, the indoor ambient temperature can be considered unchanged within the preset time after cooling stops. Specifically, the historical indoor ambient temperature corresponding to the target time before cooling stops can be determined as the indoor ambient temperature of the target air conditioner's area. The target time can be the time corresponding to the set time before cooling stops, for example, the time corresponding to 1 minute before cooling stops. The preset time can be 5 minutes. The historical indoor ambient temperature corresponding to the target time can be obtained by querying the indoor ambient temperature determined at the corresponding time when the cooling mode is on. That is, the indoor ambient temperature within 5 minutes of cooling stopping is the historical indoor ambient temperature corresponding to the target time.

[0055] When the cooling mode is off and the cooling-off time exceeds a preset duration, the first temperature can be compensated to obtain the indoor ambient temperature of the area where the target air conditioner is located. Specifically, the indoor ambient temperature of the area where the target air conditioner is located is determined based on the first temperature, the second temperature, and the inner pipe temperature.

[0056] In one possible implementation, determining the indoor ambient temperature of the area where the target air conditioner is located based on a first temperature, a second temperature, and an inner pipe temperature includes: If the difference between the first temperature and the inner pipe temperature is less than or equal to the third temperature threshold, the average of the first temperature and the second temperature is determined as the indoor ambient temperature of the area where the target air conditioner is located. If the difference between the first temperature and the inner pipe temperature is greater than the third temperature threshold, the first temperature is compensated according to the compensation temperature to obtain the indoor ambient temperature of the area where the target air conditioner is located. The compensation temperature is obtained by using correction parameters, the first temperature and the inner pipe temperature. The correction parameters are obtained by using multiple sets of experimental data.

[0057] In this embodiment, after cooling is stopped, the cold air in the evaporator sinks, significantly affecting the second temperature in the lower region of the return air vent, but having a smaller impact on the first temperature in the upper region of the return air vent. The indoor temperature has a greater impact on the first temperature. When the difference between the first temperature and the inner pipe temperature is less than or equal to the third temperature threshold, it indicates that the cold air in the evaporator has been largely dissipated, and its impact on the first and second temperatures is minimal. The average of the first and second temperatures can then be determined as the indoor ambient temperature of the area where the target air conditioner is located.

[0058] When the difference between the first temperature and the inner pipe temperature exceeds the third temperature threshold, the evaporator's cold storage capacity causes the first temperature to be too low. This can be compensated by a temperature compensation mechanism to obtain the indoor ambient temperature of the target air-conditioned area. The third temperature threshold can be the same as the first temperature threshold. The compensation temperature can be obtained from correction parameters, the first temperature, and the inner pipe temperature. The correction parameters are obtained from multiple sets of experimental data.

[0059] The correction parameters may include a first correction parameter and a second correction parameter, and the compensation formula may be: (1) in, The indoor ambient temperature of the area where the target air conditioner is located. The first temperature, To compensate for temperature, among which, Let A be the inner tube temperature, B be the first correction parameter, and C be the second correction parameter.

[0060] Figure 3 This is a flowchart illustrating a method for determining correction parameters according to an exemplary embodiment, such as... Figure 3 As shown, in one possible implementation, the method for determining the correction parameter may be as follows: In step S301, multiple sets of experimental data are acquired. Each set of experimental data includes the indoor experimental ambient temperature, the experimental temperature corresponding to the upper end of the return air vent of the experimental air conditioner, and the experimental inner pipe temperature of the experimental air conditioner.

[0061] In step S302, linear fitting is performed on multiple sets of experimental data to obtain correction parameters.

[0062] In this embodiment, multiple sets of experimental data can be obtained based on an experimental air conditioner. The experimental air conditioner is the same model as the target air conditioner. Each set of experimental data includes the indoor experimental ambient temperature, the experimental temperature corresponding to the upper end of the return air vent of the experimental air conditioner, and the experimental internal pipe temperature of the experimental air conditioner. The indoor experimental ambient temperature can be determined by uniformly arranging multiple temperature measurement sensors within the experimental test area and using the average value obtained from these sensors. The experimental temperature corresponding to the upper end of the return air vent of the experimental air conditioner can be detected by a third sensor located at the upper end of the return air vent, with the third sensor positioned at the same location as the first sensor. Linear fitting can then be performed on the multiple sets of experimental data to obtain the correction parameters.

[0063] In one possible implementation, the correction parameter may include a first correction parameter and a second correction parameter.

[0064] Linear fitting was performed on multiple sets of experimental data to obtain correction parameters, including: Determine the room temperature difference and inner tube difference for each set of experimental data. The room temperature difference is obtained by subtracting the experimental temperature from the indoor experimental ambient temperature, and the inner tube difference is obtained by subtracting the experimental inner tube temperature from the experimental temperature. Perform linear fitting on the room temperature difference and inner tube difference for multiple sets of experimental data to obtain the fitting curve between the room temperature difference and the inner tube difference. Determine the slope of the fitting curve as the first correction parameter, and determine the constant value of the fitting curve as the second correction parameter.

[0065] In this embodiment, the room temperature difference and the inner tube difference can be linearly related. The room temperature difference and the inner tube difference corresponding to each set of experimental data can be calculated, and then the room temperature difference and the inner tube difference can be fitted to obtain a fitting curve based on the room temperature difference and the inner tube difference.

[0066] Specifically, in the process of linear fitting multiple sets of experimental data, the room temperature difference can be used as a basis. Difference between inner tube and outer tube To perform a linear fit, the formula for the linear fit can be: (2) in, The value is obtained by subtracting the experimental temperature from the indoor experimental environment temperature. The value obtained by subtracting the temperature of the inner tube from the experimental temperature is A, which is the first correction parameter and B is the second correction parameter.

[0067] By using the above linear fitting formula to linearly fit the room temperature difference and inner tube difference corresponding to multiple sets of experimental data, the fitting curve can be obtained. Then, the slope of the fitting curve can be determined as the first correction parameter, and the constant value of the fitting curve can be determined as the second correction parameter, that is, the specific values ​​of A and B can be obtained.
