FIG. 3 is a schematic diagram of a control method of the air conditioner 10 according to an embodiment of the present invention. The control method may generally include:

Step S302 , obtain the outdoor temperature prediction information of the location where the air conditioner 10 is located.

The location where the air conditioner 10 is located may refer to the prefecture-level administrative region where the air conditioner 10 is located, or may refer to the county-level administrative region, or other administrative regions.

The step of acquiring the predicted outdoor temperature information at the location of the air conditioner 10 may include: sending a query request to a cloud platform data-connected with the air conditioner 10 to acquire the outdoor temperature at the location of the air conditioner 10 corresponding to the location information of the air conditioner 10 For prediction information, the cloud platform may store real-time data of outdoor temperature prediction information at the location corresponding to the location information of the air conditioner 10 , and the location information of the air conditioner 10 is pre-configured in the cloud platform.

In this embodiment, according to the preset location information, the cloud platform can establish a data connection with the weather forecast application platform, and can periodically collect the weather forecast data of the location of the air conditioner 10 corresponding to the location information in the weather forecast application platform, For example, weather forecast data can be collected every 10 minutes. The weather forecast data includes prediction information on the outdoor temperature of the location where the air conditioner 10 is located.

The outdoor temperature prediction information may refer to the temperature prediction information in the weather forecast data, that is, the temperature at each moment in the future set time period, for example, the temperature at each hour in the next 24 hours. The set time period can be 24h, 48h, or 12h, etc.

Step S304 , according to the outdoor temperature prediction information, determine the condensation conditions that the indoor environment where the indoor unit 110 of the air conditioner 10 is located needs to reach for a frost and dew condensation event to occur. When the indoor environment reaches condensation conditions, frost and/or condensation may occur at the condensation locations in the indoor environment. The condensation location in the indoor environment refers to a location in the indoor environment where the temperature difference between the indoor environment and the outdoor environment where the outdoor unit is located is small, such as a glass window. The temperature of the glass window can be close to the outdoor ambient temperature. When the outdoor ambient temperature is low and the indoor ambient humidity is high, frost and/or condensation may occur on the glass window.

Wherein, the outdoor temperature prediction information records the corresponding relationship of the outdoor ambient temperature changing with time. And the step of determining, according to the outdoor temperature prediction information, the condensation conditions required for the occurrence of a frost and dew condensation event in the indoor environment may include: judging, according to the outdoor temperature prediction information, whether the indoor environment where the indoor unit 110 of the air conditioner 10 is located is prone to a frost and dew condensation event. The dew condensation event includes a frost condensation event and/or a dew condensation event. If so, the condensation condition that needs to be reached for the occurrence of a frost and dew condensation event in the indoor environment is further determined according to the outdoor temperature prediction information. Indoor environment prone to frost and dew condensation events means that there is a risk of frost and dew condensation events in the indoor environment. When the outdoor ambient temperature is low, for example, when the outdoor environment is lower than 0°C, the indoor environment is prone to frost and dew condensation events.

The step of judging whether the indoor environment where the indoor unit 110 of the air conditioner 10 is located is prone to frost and dew condensation events according to the outdoor temperature prediction information may include: judging whether all the outdoor ambient temperatures recorded in the outdoor temperature prediction information are greater than or equal to a first set threshold, If not, it is determined that the indoor environment is prone to frost and dew condensation events, and if yes, it is determined that the indoor environment is not prone to frost and dew condensation events.

The first set threshold can be preset according to actual needs. For example, it can be 0°C, or any value in the range of -10°C to 0°C, or any value in the range of 0°C to 5°C.

By analyzing the outdoor temperature prediction information, when part of the outdoor ambient temperature in the outdoor temperature prediction information is lower than the first set threshold, further determine the condensation conditions that the indoor environment needs to reach for a frost and dew condensation event according to the outdoor temperature prediction information, so that The operation state of the air conditioner 10 is adjusted in time so that the indoor environment cannot reach the condensation condition, thereby reducing or avoiding the occurrence of frost and dew condensation events in the indoor environment.

In this embodiment, the above-mentioned condensation conditions may include indoor environmental conditions and time conditions that are required for a frost and dew condensation event to occur in the indoor environment.

The indoor environmental conditions stipulate the indoor environmental parameter thresholds that need to be reached for the occurrence of frost and dew condensation events in the indoor environment, and the indoor environmental parameter thresholds at least include indoor condensation humidity thresholds. The indoor condensation humidity threshold refers to the humidity required for the occurrence of frost and dew condensation events in the indoor environment when the outdoor ambient temperature reaches the risk temperature. In some optional embodiments, the indoor environmental parameter threshold may further include an indoor condensation temperature threshold.

Determining the time condition that the frost condensation event occurs in the indoor environment is used to determine the time when the frost condensation event occurs, so as to take measures in advance to prevent the occurrence of the frost condensation event.

The step of determining, according to the outdoor temperature prediction information, the condensation conditions required for the occurrence of a frost and dew condensation event in the indoor environment may include: extracting the outdoor ambient temperature and its corresponding time less than the first set threshold in the outdoor temperature prediction information, and denoting them as the risk temperature respectively and risk time, the indoor environmental conditions are determined according to the risk temperature, and the time conditions are determined according to the risk time. During the risk time, the outdoor ambient temperature will reach the risk temperature, and the indoor environment is prone to frost and condensation events.

The step of determining the indoor environmental conditions according to the risk temperature may include: acquiring a preset temperature and humidity correspondence, which specifies an indoor condensation and humidity threshold that needs to be reached for a frost condensation event in the indoor environment corresponding to each risk temperature , and determine the indoor condensation humidity threshold according to the corresponding relationship of temperature and humidity. Under different risk temperatures, the minimum humidity value required for the occurrence of frost and dew condensation events in the indoor environment can be determined, and the above-mentioned corresponding relationship of temperature and humidity can be obtained.

In the step of determining the time condition according to the risk time, the risk time may be directly used as the time condition. For example, if the time corresponding to the outdoor ambient temperature less than the first set threshold in the outdoor temperature prediction information is 3:00am-5:00am, the risk time is 3:00am-5:00am.

Step S306, it is determined whether the indoor environment is about to reach the condensation condition. For example, before reaching the time condition, it can be judged whether the indoor environment reaches the indoor environment condition according to various parameters of the indoor environment, so as to judge whether the indoor environment is about to reach the condensation condition.

Indoor environmental conditions specify the thresholds of indoor environmental parameters that must be met for frost and dew condensation events to occur in the indoor environment. And the step of judging whether the indoor environment is about to reach the condensation condition may include: in a set time period before reaching the time condition, detecting the indoor environment parameter of the indoor environment, and judging whether the difference between the indoor environment parameter and the threshold value of the indoor environment parameter is not. is less than the second set threshold, if yes, it is determined that the indoor environment is about to reach the condensation condition; if not, it is determined that the indoor environment is not about to reach the condensation condition. The set time period can be any value within the range of 0.1h to 1h. The indoor environment parameter may include at least the indoor environment humidity, and accordingly, the indoor environment parameter threshold may include at least the indoor environment humidity threshold, and the difference between the indoor environment parameter and the indoor environment parameter threshold refers to the difference between the indoor environment humidity and the indoor environment humidity threshold. The absolute value of , the second set threshold can be set according to the actual situation, for example, can be any value within the range of 1% to 10%. For example, the air conditioner 10 may drive a humidity sensor to detect a real-time value of indoor ambient humidity.

In step S308, if the indoor environment is about to reach the condensation condition, the air conditioner 10 is controlled to adjust the operating state to prevent frost and dew condensation events from occurring in the indoor environment. When the indoor environment is about to reach the condensation condition, by controlling the air conditioner 10 to adjust the operating state, the occurrence of frost and dew condensation events in the indoor environment can be prevented. Using the above method, the air conditioner 10 of this embodiment can automatically prevent the occurrence of frost and dew condensation events, thereby improving the degree of intelligence.

The step of controlling the air conditioner 10 to adjust the operating state to prevent the occurrence of frost and dew condensation events in the indoor environment may include: acquiring temperature field information of the indoor environment, the temperature field information containing the temperature and/or temperature change curve of each position in the indoor environment, according to The temperature field information determines the target operating parameters of the air conditioner 10, and controls the air conditioner 10 to adjust the operating state according to the target operating parameters. The temperature change curve of each position in the indoor environment refers to a curve of the temperature of each position in the indoor environment changing with time.

The target operating parameters of the air conditioner 10 may include a target blowing angle of the indoor unit 110 of the air conditioner 10 . And the step of determining the target operating parameters of the air conditioner 10 according to the temperature field information includes: determining the condensation position where frost and dew condensation events are likely to occur in the indoor environment according to the temperature field information, and determining the target air supply of the indoor unit 110 of the air conditioner 10 according to the condensation position. angle. For example, the temperature field information can be the real-time temperature of each position in the indoor environment, and the position where the real-time temperature in the temperature field information is lower than the third set threshold can be used as the condensation position, and the third set threshold can be any value less than 5°C . In general, the real-time temperature of the glass window is relatively low. If it is detected that the real-time temperature of the glass window is lower than the third set threshold, the position of the glass window is recorded as the condensation position.

The coagulation position can be a coordinate, and the offset angle of the coagulation position relative to the indoor unit 110 can be directly calculated according to the coordinates of the coagulation position. The offset angle is a vector sum of the deviation angle of the condensation position from the indoor unit 110 in the horizontal direction and the deviation angle of the condensation position from the indoor unit 110 in the vertical direction. After the offset angle is determined, the target air supply angle of the indoor unit 110 can be directly determined according to the offset angle, and then the air supply components of the indoor unit 110 (for example, the swing vane or the air deflector 111) can be controlled to rotate to the target air supply angle. corresponding location. After the target air supply angle is determined, the indoor unit 110 of the air conditioner 10 can be driven to enter the heating mode according to the target air supply angle, so that the air supply air is blown toward the condensation position, so that the condensation position is surrounded by warm air flow, which can improve the proper Increase the temperature at the condensation location to prevent frost condensation events at the condensation location.

The wind speed and air volume of the air supply air flow and the operating temperature in the heating mode can be preset according to the size of the indoor environment where the indoor unit 110 of the air conditioner 10 is located, the distance from the glass window, and the like.

In some other optional embodiments, the air conditioner 10 may further have a plurality of dehumidification units, which are respectively disposed in the indoor environment and used for consuming water vapor in the indoor environment. Each dehumidification unit is correspondingly provided with a dehumidification position, and each dehumidification position corresponds to a dehumidification working range. The union of the dehumidification work ranges of a plurality of dehumidification units can form the space where the entire indoor environment is located. The dehumidification unit in the dehumidification position can dehumidify the indoor environment within the corresponding dehumidification working range.

The step of controlling the air conditioner 10 to adjust the operating state to prevent the occurrence of frost and dew condensation events in the indoor environment may further include: driving at least one dehumidification unit corresponding to the condensation position to start operation. For example, the corresponding dehumidification position may be determined according to the condensation position, and then at least one dehumidification unit corresponding to the dehumidification position is driven to start running. If the condensation position coincides with the dehumidification position of a dehumidification unit, the condensation position is directly regarded as the dehumidification position. If the condensation position does not coincide with the dehumidification position of any dehumidification unit, the dehumidification position closest to the condensation position is regarded as the condensation position. The corresponding dehumidification position.

Using the above method, the air conditioner 10 of this embodiment can drive the corresponding dehumidification unit to start operation according to the condensation position, so that a suitable humidity atmosphere can be quickly created around the condensation position in a targeted manner, and the dehumidification effect around the condensation position is improved. It also saves energy consumption, and only needs to dehumidify the designated area in the indoor environment to achieve a good anti-frost effect.
