Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular, to a control method for an air conditioner, a control device for an air conditioner, a computer-readable storage medium, and an air conditioner. Background Art

[0002] Generally speaking, an air conditioner is a device used to cool or heat indoor air. This device discharges air (cold air or warm air) that undergoes heat exchange according to the characteristics that liquid refrigerant absorbs surrounding heat when vaporizing and releases its heat when liquefying by applying a usual refrigeration cycle of circulating refrigerant, thereby adjusting the indoor temperature. Currently, in order to control the air flow (wind direction and air volume) of the discharged air, an air conditioner is provided with a fan and blades. The air volume is set by people through the remote control or the buttons on the air conditioner, or set to automatic.

[0003] Currently, the automatic wind of an air conditioner is judged based on the difference between the indoor temperature and the set temperature, and different wind gears are operated. Even when the compressor stops, the corresponding fan gear is still operated according to the temperature difference. When the temperature difference is large, it is easy to cause a sudden change in wind speed. In related technologies, in order to solve the influence of wind speed fluctuations caused by temperature fluctuations in the automatic wind control scheme, time processing is added. Each wind speed runs for at least this time before judging the change in temperature difference for adjusting the fan gear. However, when the temperature changes suddenly, it is still easy to cause a sudden change in the fan speed, thereby causing a change in noise and bringing a poor user experience to users. Summary of the Invention

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0034] The control method of the air conditioner, the control device of the air conditioner, the computer-readable storage medium, and the air conditioner proposed by the embodiments of the present invention will be described below with reference to the drawings.

[0035] Figure 1Flow chart of the control method of an air conditioner according to an embodiment of the present invention.

[0036] As Figure 1 shown, the control method of the air conditioner according to the embodiment of the present invention may include the following steps:

[0037] S1. When the automatic wind function of the air conditioner is turned on, obtain the indoor temperature.

[0038] S2. When the indoor temperature changes, obtain the first indoor temperature before the change and the second indoor temperature after the change of the indoor temperature.

[0039] S3. Obtain the first temperature difference between the second indoor temperature and the first indoor temperature, and determine the temperature offset according to the first temperature difference.

[0040] S4. Determine the third indoor temperature according to the first indoor temperature or the second indoor temperature, and the temperature offset.

[0041] S5. Based on the third indoor temperature, determine the target speed of the indoor fan of the air conditioner, and control the operation of the indoor fan according to the target speed.

[0042] Specifically, in the cooling mode, heating mode or air supply mode of the air conditioner, the user can choose whether to turn on the automatic wind function. For example, the user can turn on the automatic function through the remote control or the button on the air conditioner, or can also control the opening of the automatic wind function through the mobile device connected to the air conditioner in its application program. After the automatic wind function is turned on, the wind speed of the indoor fan can be determined according to the actual situation. For example, the speed of the indoor fan can be determined according to the indoor temperature. The higher the indoor temperature, the higher the speed of the indoor fan; the lower the indoor temperature, the lower the speed of the indoor fan, so as to adaptively adjust the wind speed and improve the user experience. Another example is that the speed of the indoor fan can be determined according to the outdoor ambient temperature. The higher the outdoor ambient temperature, the higher the speed of the indoor fan; the lower the outdoor ambient temperature, the lower the speed of the indoor fan, so as to adaptively adjust the wind speed and improve the user experience.

[0043] If the automatic wind function of the air conditioner is in the off state, the indoor fan can operate at the set wind speed. For example, the user can set the size of the wind speed through the remote control or the button on the air conditioner. The greater the wind speed, the greater the speed of the indoor fan; the smaller the wind speed, the smaller the speed of the indoor fan, so that the indoor fan can operate at the wind speed set by the user.

[0044] When the automatic wind function of the air conditioner is turned on, the indoor temperature can be obtained through the indoor temperature sensor. To prevent frequent changes in the wind speed caused by fluctuations in the indoor temperature, which may lead to noise problems, when the indoor temperature changes, instead of directly using the changed temperature to calculate the indoor fan wind speed, a certain temperature value during the temperature change process is used for calculation.

[0045] That is to say, when the indoor temperature changes, the first indoor temperature before the change and the second indoor temperature after the change of the indoor temperature can be obtained through the indoor temperature sensor. For example, when the air conditioner operates in the cooling mode in summer, when the indoor temperature reaches the user-set value, to achieve energy-saving purposes and prevent a further decrease in temperature from bringing a poor experience to the user, the compressor of the air conditioner will stop running. After the compressor stops running, the indoor ambient temperature will rise. Thus, the first indoor temperature before the rise and the second indoor temperature after the rise of the indoor temperature can be obtained through the temperature sensor. Another example is that when the air conditioner operates in the heating mode in winter, after the indoor temperature reaches the user-set temperature, the compressor stops running. After the compressor stops running, the indoor temperature will decrease. Thus, the first indoor temperature before the decrease and the second indoor temperature after the decrease of the indoor temperature can be obtained through the temperature sensor.

[0046] After obtaining the second indoor temperature and the first indoor temperature, the first temperature difference between the second indoor temperature and the first indoor temperature can be obtained. It should be noted that the first temperature difference is positive. That is to say, when the indoor temperature rises, the second indoor temperature is greater than the first indoor temperature, so the first temperature difference can be determined as the second indoor temperature minus the first indoor temperature; when the indoor temperature drops, the second indoor temperature is less than the first indoor temperature, so the first temperature difference can be determined as the first indoor temperature minus the second indoor temperature. After obtaining the first temperature difference, the temperature offset can be determined according to the first temperature difference. For example, the temperature offset can be determined through a pre-set corresponding relationship. For example, the relationship between the first temperature difference and the temperature offset is determined in advance. After the first temperature difference is determined, the corresponding relationship can be directly called to obtain the temperature offset.

[0047] After obtaining the temperature offset, the third indoor temperature can be determined based on the first indoor temperature and the temperature offset, or the third indoor temperature can be determined based on the second indoor temperature and the temperature offset. For example, when the indoor temperature rises and the second indoor temperature is greater than the first indoor temperature, the third indoor temperature can be determined by adding the temperature offset to the first indoor temperature to reduce the temperature change amount. Alternatively, the third indoor temperature can be determined by subtracting the temperature offset from the second indoor temperature to reduce the temperature change amount, thereby enabling a more stable indoor fan speed to be calculated. Another example is when the indoor temperature drops and the second indoor temperature is less than the first indoor temperature. The third indoor temperature can be determined by adding the temperature offset to the second temperature to reduce the temperature change amount, or the third indoor temperature can be determined by subtracting the temperature offset from the first indoor temperature to reduce the temperature change amount, thereby enabling a more stable indoor fan speed to be calculated.

[0048] After obtaining the third indoor temperature, the target speed of the indoor fan of the air conditioner can be determined based on the third indoor temperature. For example, the target speed of the indoor fan can be determined through a pre-set corresponding relationship. For instance, the relationship between the third indoor temperature and the target speed is determined in advance, and after the third indoor temperature is determined, the corresponding relationship can be directly called to obtain the target speed. After obtaining the target speed, the indoor fan can be controlled to operate at the target speed, thereby preventing the noise problem caused by the frequent change of the wind speed due to the temperature fluctuation and improving the user experience.

[0049] According to an embodiment of the present invention, determining the temperature offset according to the first temperature difference includes: obtaining the first ratio of the first temperature difference to the first preset coefficient to obtain the temperature offset. Wherein, the first preset coefficient can be determined according to the actual situation, and the first preset coefficient can be a value greater than or equal to 1.

[0050] Specifically, when determining the temperature offset according to the first temperature difference, it can be determined according to the ratio of the first temperature difference to the first preset coefficient, that is, the first ratio is the first temperature difference divided by the first preset coefficient. For example, after calculation, the first temperature difference is 2 degrees Celsius. When the first preset coefficient is 2, the first ratio can be determined to be 1, that is, the temperature offset is 1 degree Celsius.

[0051] According to an embodiment of the present invention, determining the third indoor temperature according to the first indoor temperature or the second indoor temperature, and the temperature offset includes: obtaining the sum of the first indoor temperature and the temperature offset to obtain the third indoor temperature; or obtaining the difference between the second indoor temperature and the temperature offset to obtain the third indoor temperature.

[0052] Specifically, when determining the temperature in the third chamber, it can be determined according to the temperature in the first chamber and the temperature offset. For example, when the indoor temperature rises from the temperature in the first chamber to the temperature in the second chamber, in order to reduce the temperature change amount and obtain a stable rotational speed of the indoor fan, the temperature in the first chamber can be added to the temperature offset to obtain the temperature in the third chamber. For example, if the temperature in the first chamber is 22 degrees Celsius, the temperature in the second chamber is 24 degrees Celsius, and the temperature offset is calculated to be 1 degree Celsius through calculation, the temperature in the third chamber can be determined to be 23 degrees Celsius.

[0053] When determining the temperature in the third chamber, it can also be determined according to the temperature in the second chamber and the temperature offset. For example, the temperature in the second chamber can be subtracted by the temperature offset to obtain the temperature in the third chamber. For example, if the temperature in the first chamber is 23 degrees Celsius, the temperature in the second chamber is 25 degrees Celsius, and the temperature offset is calculated to be 1 degree Celsius through calculation, the temperature in the third chamber can be determined to be 24 degrees Celsius.

[0054] According to an embodiment of the present invention, determining the target rotational speed of the indoor fan of the air conditioner based on the temperature in the third chamber includes: obtaining a second temperature difference between the target indoor temperature and the temperature in the third chamber; determining the target rotational speed of the indoor fan based on the second temperature difference.

[0055] Specifically, when determining the target rotational speed of the indoor fan of the air conditioner according to the temperature in the third chamber, the second temperature difference between the target indoor temperature and the temperature in the third chamber can be obtained first, and the target rotational speed of the indoor fan can be determined according to the second temperature difference. For example, the target rotational speed of the indoor fan can be determined through a pre-set corresponding relationship. For example, the relationship between the second temperature difference and the target rotational speed is determined in advance. After the second temperature difference is determined, the corresponding relationship can be directly called to obtain the target rotational speed.

[0056] Different second temperature differences correspond to different target rotational speeds of the indoor fan. For example, the larger the second temperature difference, the larger the target rotational speed of the indoor fan, so that the indoor temperature can quickly reach the target indoor temperature. The smaller the second temperature difference, the smaller the target rotational speed of the indoor fan, so as to achieve the purpose of saving electricity.

[0057] According to an embodiment of the present invention, the control method of the air conditioner further includes: obtaining the outdoor ambient temperature; determining the target rotational speed of the indoor fan of the air conditioner based on the outdoor ambient temperature and the temperature in the third chamber.

[0058] Specifically, if the automatic wind function of the air conditioner is turned on, when the outdoor ambient temperature is high, the heat radiation is large. If the fan speed is determined only based on the indoor temperature and the indoor temperature difference is small, the fan still needs to operate at a high frequency to maintain the heat load balance when the wind speed is reduced, resulting in high power consumption. Therefore, in an embodiment of the present invention, the target speed of the indoor fan is related not only to the temperature difference between the indoor temperature and the target indoor temperature, but also to the outdoor ambient temperature. The outdoor ambient temperature can be obtained through an outdoor temperature sensor. After obtaining the outdoor ambient temperature, the target speed of the indoor fan of the air conditioner can be determined according to the outdoor temperature and the third indoor temperature.

[0059] For example, according to a preset table in which multiple outdoor ambient temperatures, third indoor temperatures, and the target speeds of the indoor fan are stored, and the outdoor ambient temperature, the third indoor temperature, and the target speed of the indoor fan are in a corresponding relationship. After determining an outdoor ambient temperature and a third indoor temperature, the target speed of the indoor fan can be determined according to the corresponding relationship.

[0060] According to an embodiment of the present invention, determining the target speed of the indoor fan of the air conditioner based on the outdoor ambient temperature and the third indoor temperature includes: obtaining a second temperature difference between the target indoor temperature and the third indoor temperature, and determining a temperature range or a temperature coefficient corresponding to the outdoor ambient temperature; and determining the target speed of the indoor fan according to the temperature range or the temperature coefficient and the second temperature difference.

[0061] Specifically, when determining the target speed of the indoor fan of the air conditioner according to the outdoor ambient temperature and the third indoor temperature, the second temperature difference between the target indoor temperature and the third indoor temperature can be calculated first. It should be noted that the second temperature difference is positive. That is, when the target indoor temperature is greater than the third indoor temperature, the second temperature difference is the target indoor temperature minus the third indoor temperature; when the target indoor temperature is less than the third indoor temperature, the second temperature difference is the third indoor temperature minus the target indoor temperature.

[0062] Determine the temperature range or the temperature coefficient corresponding to the outdoor ambient temperature. Different outdoor ambient temperatures correspond to different temperature ranges or temperature coefficients. For example, the outdoor ambient temperature can be divided into multiple temperature ranges. For example, the first temperature range is 18°C to 20°C, the second temperature range is 20°C to 22°C, the third temperature range is 22°C to 24°C, etc. When dividing the temperature ranges, they can be divided according to the same temperature interval, or in an increasing manner or other ways. Thus, it can be determined that the current outdoor ambient temperature is in the corresponding temperature range. The relationship between the outdoor ambient temperature and the temperature coefficient can also be determined in advance. After the outdoor ambient temperature is determined, the corresponding relationship can be directly called to obtain the temperature coefficient.

[0063] After determining the temperature range or the temperature coefficient, the target speed of the indoor fan can be determined according to the temperature range and the second temperature difference. For example, according to the pre-determined relationship between the temperature range, the second temperature difference and the speed of the indoor fan, after determining the temperature range and the second temperature difference, the corresponding relationship can be directly called to obtain the target speed of the indoor fan. Or the target speed of the indoor fan can also be determined according to the temperature coefficient and the second temperature difference. For example, according to the pre-determined relationship between the temperature coefficient, the second temperature difference and the speed of the indoor fan, after determining the temperature coefficient and the second temperature difference, the corresponding relationship can be directly called to obtain the target speed of the indoor fan.

[0064] According to an embodiment of the present invention, determining the temperature coefficient corresponding to the outdoor ambient temperature includes: obtaining a third temperature difference between a reference temperature and the outdoor ambient temperature; obtaining a second ratio of the third temperature difference to the reference temperature; obtaining a difference between a second preset coefficient and the second ratio to obtain the temperature coefficient. Wherein, the reference temperature can be determined according to the actual situation, and the second preset coefficient can be determined according to the actual situation.

[0065] Specifically, when determining the temperature coefficient corresponding to the outdoor ambient temperature, the third temperature difference between the reference temperature and the outdoor ambient temperature can be obtained first, and then the second ratio of the third temperature difference to the reference temperature can be obtained. The temperature coefficient corresponding to the outdoor ambient temperature can be determined by calculating the difference between the second preset coefficient and the second ratio.

[0066] For example, when the reference temperature is greater than the outdoor ambient temperature, if the reference temperature is set to 30 °C and the second preset coefficient is 2, when the indoor temperature is 27 °C, the third temperature difference can be determined to be 3 °C, and then according to the third temperature difference of 3 °C and the reference temperature of 30 °C, the second ratio is determined to be 0.1. According to the second preset coefficient of 2 minus the second ratio of 0.1, the temperature coefficient can be determined to be 1.9. In addition, when the reference temperature is less than the outdoor ambient temperature, when the indoor ambient temperature is 33 °C, the third temperature difference can be determined to be the outdoor ambient temperature minus the reference temperature, that is, 3 °C, and then according to the third temperature difference of 3 °C and the reference temperature of 30 °C, the second ratio can be determined to be 0.1. According to the second preset coefficient of 2 plus the second ratio of 0.1, the temperature coefficient can be determined to be 2.1. Thus, a smaller temperature coefficient can be determined when the outdoor ambient temperature is lower, and a larger temperature coefficient can be determined when the outdoor ambient temperature is higher.

[0067] According to an embodiment of the present invention, when controlling the operation of the indoor fan according to the target speed, the control method of the air conditioner further includes: when the air conditioner meets the condition of reaching the temperature and stopping, controlling the compressor of the air conditioner to stop, and controlling the indoor fan to stop after delaying for a first preset time. Wherein, the first preset time can be determined according to the actual situation.

[0068] Specifically, when controlling the operation of the indoor fan according to the target rotation speed, if the air conditioner meets the condition of stopping operation when reaching the set temperature, for example, when the current indoor temperature has reached the temperature set by the user, in order to prevent the temperature from changing further and improve the user experience, the compressor of the air conditioner can be controlled to stop. And, after the compressor stops, in order to further blow out the temperature in the evaporator into the room to ensure the stability of the indoor temperature, the indoor fan does not stop immediately, but runs for a first preset time and then is controlled to stop. For example, the first preset time can be 30 seconds. After controlling the compressor to stop, the indoor fan can be controlled to stop after running for 30 seconds.

[0069] According to an embodiment of the present invention, the control method of the air conditioner further includes: in the cooling mode, when the indoor temperature is less than or equal to the difference between the target indoor temperature and the first temperature margin, it is determined that the air conditioner meets the condition of stopping operation when reaching the set temperature; in the heating mode, when the indoor temperature is greater than or equal to the sum of the target indoor temperature and the second temperature margin, it is determined that the air conditioner meets the condition of stopping operation when reaching the set temperature. Wherein, the first temperature margin and the second temperature margin can be determined according to the actual situation.

[0070] Specifically, the air conditioner can include multiple operation modes. When the air conditioner is in the cooling mode, the indoor temperature will gradually decrease. When the indoor temperature is less than or equal to the difference between the target indoor temperature and the first temperature margin, it means that the current indoor temperature has dropped below the target indoor temperature. In order to prevent the indoor temperature from continuing to drop and improve the user experience, it can be determined that the air conditioner meets the condition of stopping operation when reaching the set temperature; when the air conditioner is in the heating mode, the indoor temperature will gradually increase. When the indoor temperature is greater than or equal to the sum of the target indoor temperature and the second temperature margin, it means that the current indoor temperature has risen above the target indoor temperature. In order to prevent the indoor temperature from continuing to rise and improve the user experience, it can be determined that the air conditioner meets the condition of stopping operation when reaching the set temperature.

[0071] It should be noted that the first temperature margin and the second temperature margin can be the same or different. For example, both the first temperature margin and the second temperature margin can be 0.5 degrees Celsius. In the cooling mode, if the indoor temperature obtained through the indoor temperature sensor is 21 degrees Celsius and the target indoor temperature is 22 degrees Celsius, which is less than the difference between the target indoor temperature and the first temperature margin, it can be determined that the air conditioner meets the condition of stopping operation when reaching the set temperature; in the heating mode, if the indoor temperature obtained through the indoor temperature sensor is 26 degrees Celsius and the target indoor temperature is 25 degrees Celsius, which is greater than the sum of the target indoor temperature and the second temperature margin, it can be determined that the air conditioner meets the condition of stopping operation when reaching the set temperature.

[0072] According to an embodiment of the present invention, after controlling the compressor of the air conditioner to stop and then controlling the indoor fan to stop after a first preset time delay, the control method of the air conditioner further includes: when the air conditioner meets the first temperature - reaching startup condition, controlling the indoor fan to run; after a second preset time delay, when the air conditioner meets the second temperature - reaching startup condition, controlling the indoor fan to continue running and controlling the compressor to run. Wherein, the second preset time can be determined according to the actual situation.

[0073] Specifically, after controlling the compressor of the air conditioner to stop and then controlling the indoor fan to stop after a first preset time delay, in order to prevent the indoor temperature from not circulating and causing inaccurate indoor temperature acquisition, when the air conditioner meets the first temperature - reaching startup condition, for example, in the cooling mode, when the indoor temperature is equal to the temperature set by the user (target indoor temperature), the indoor fan can be controlled to run for the second preset time first, and then it is judged whether the air conditioner meets the second temperature - reaching startup condition. If the air conditioner meets the second temperature - reaching startup condition, for example, in the cooling mode, when the indoor temperature exceeds the temperature set by the user, the indoor fan can be controlled to continue running and the compressor can be controlled to run, so as to reduce the indoor temperature and improve the user comfort.

[0074] For another example, in the heating mode, when the indoor temperature is equal to the temperature set by the user, the indoor fan can be controlled to run for the second preset time first, and then when the indoor temperature is lower than the temperature set by the user, the indoor fan can be controlled to continue running and the compressor can be controlled to run, so as to increase the indoor temperature and improve the user comfort.

[0075] According to an embodiment of the present invention, the control method of the air conditioner further includes: in the cooling mode, when the indoor temperature is greater than the sum of the target indoor temperature and the third temperature margin, it is determined that the air conditioner meets the first temperature - reaching startup condition; when the indoor temperature is greater than the sum of the target indoor temperature and the fourth temperature margin, it is determined that the air conditioner meets the second temperature - reaching startup condition; in the heating mode, when the indoor temperature is less than the difference between the target indoor temperature and the fifth temperature margin, it is determined that the air conditioner meets the first temperature - reaching startup condition; when the indoor temperature is less than the difference between the target indoor temperature and the sixth temperature margin, it is determined that the air conditioner meets the second temperature - reaching startup condition. Wherein, the third temperature margin, the fourth temperature margin, the fifth temperature margin and the sixth temperature margin can be determined according to the actual situation.

[0076] Specifically, when the air conditioner is in the cooling mode, compare the indoor temperature with the sum of the target indoor temperature and the third temperature margin. When the indoor temperature is greater than the sum of the target indoor temperature and the third temperature margin, it indicates that the current indoor temperature is rising continuously. At this time, it can be determined that the air conditioner meets the first temperature-reaching startup condition. To prevent inaccurate temperature acquisition, the indoor fan can be controlled to operate. Then compare the indoor temperature with the sum of the target indoor temperature and the fourth temperature margin. When the indoor temperature is greater than the sum of the target indoor temperature and the fourth temperature margin, it indicates that the current indoor temperature is stable and further increasing. At this time, it can be determined that the air conditioner meets the second temperature-reaching startup condition. To lower the indoor temperature, the indoor fan can be controlled to continue operating, and the compressor can be controlled to operate. When the indoor temperature is less than the sum of the target indoor temperature and the fourth temperature margin, it indicates that the current indoor temperature is not increasing significantly, and the compressor can be controlled to remain in the shutdown operation state. It should be noted that the third temperature margin and the fourth temperature margin can be the same or different.

[0077] When the indoor temperature is less than the sum of the target indoor temperature and the third temperature margin, such as less than the sum of the target indoor temperature and the third temperature margin minus the preset value, that is, when the indoor temperature is close to the target indoor temperature, the indoor fan can be controlled to stop operating.

[0078] When the air conditioner is in the heating mode, compare the indoor temperature with the difference between the target indoor temperature and the fifth temperature margin. When the indoor temperature is less than the difference between the target indoor temperature and the fifth temperature margin, it indicates that the current indoor temperature is decreasing continuously. At this time, it can be determined that the air conditioner meets the first temperature-reaching startup condition. To prevent inaccurate temperature acquisition, the indoor fan can be controlled to operate. Then compare the indoor temperature with the difference between the target indoor temperature and the sixth temperature margin. When the indoor temperature is less than the difference between the target indoor temperature and the sixth temperature margin, it indicates that the current indoor temperature is stable and further decreasing. At this time, it can be determined that the air conditioner meets the second temperature-reaching startup condition. To increase the indoor temperature, the indoor fan can be controlled to continue operating, and the compressor can be controlled to operate. When the indoor temperature is greater than the difference between the target indoor temperature and the sixth temperature margin, it indicates that the current indoor temperature is not decreasing significantly, and the compressor can be controlled to remain in the shutdown operation state. It should be noted that the fifth temperature margin and the sixth temperature margin can be the same or different.

[0079] When the indoor temperature is greater than the difference between the target indoor temperature and the fifth temperature margin, such as greater than the difference between the target indoor temperature and the fifth temperature margin plus the preset value, that is, when the indoor temperature is close to the target indoor temperature, the indoor fan can be controlled to stop operating.

[0080] According to an embodiment of the present invention, before controlling the indoor fan to stop after delaying for a first preset time, the method further includes: obtaining user parameters; when it is determined based on the user parameters that the indoor fan needs to be controlled to stop, controlling the indoor fan to stop after delaying for the first preset time; when it is determined based on the user parameters that the indoor fan does not need to be controlled to stop, controlling the indoor fan to continue running.

[0081] Specifically, when the user is resting at night, in order to avoid the noise problem caused by the frequent startup, shutdown, and restart of the indoor fan, before controlling the indoor fan to stop after delaying for the first preset time, user parameters can also be obtained. That is, buttons or combination buttons can be added to the air conditioner. For example, when the user presses the button, an instruction to stop the indoor fan after the compressor stops can be issued, and when the user does not press the button, an instruction to continue running the indoor fan after the compressor stops can be issued. Thus, when it is determined based on the user parameters that the indoor fan needs to be controlled to stop, the indoor fan can be controlled to stop after delaying for the first preset time, thereby achieving an energy-saving effect. When it is determined based on the user parameters that the indoor fan does not need to be controlled to stop, the indoor fan can be controlled to continue running, thereby reducing the noise problem and improving the user experience.

[0082] The following combines Figure 2 to describe the control method of the present invention.

The third indoor temperature is determined according to the first indoor temperature or the second indoor temperature and the temperature offset. The target speed of the indoor fan of the air conditioner is determined based on the third indoor temperature, and the indoor fan is controlled to run according to the target speed.
