[0002] During daily use of the air conditioner for cooling, if the indoor humidity is high and the air outlet temperature of the air conditioner is low, a large amount of condensation water is likely to be generated at the air outlet or air guide plate when the air outlet of the air conditioner outputs cold air for a long time.

[0003] At present, in order to avoid a large amount of condensed water on the air outlet or air guide plate caused by long-term cold air output, the air conditioner reduces the operating frequency of the compressor after the air conditioner has been running for a period of time to increase the air outlet temperature, thereby improving the condensation phenomenon.

[0056] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0057] Figure 1 is a flow chart of a control method of an air conditioner according to an exemplary embodiment. The method is applied to an air conditioner, which is not limited to a cabinet or a mobile air conditioner. The air conditioner includes a plurality of air outlets, such as Figure 1 As shown, the method may include the following steps:

[0058] In step S101, the indoor dew point temperature and the inner pipe temperature of the air conditioner are acquired.

[0059] The indoor dew point temperature is used to characterize the temperature of indoor air when it is cooled to saturation without changing the water vapor content and air pressure. In other words, the temperature when the water vapor in the air turns into dew is called the dew point temperature. The inner tube temperature is the inner tube temperature of the heat exchanger in the air conditioner. The lower the inner tube temperature, the lower the air outlet temperature of the air conditioner.

[0060] In this embodiment, in view of the fact that condensed water may be generated in the cooling mode of the air conditioner, in order to ensure the normal use of the air conditioner and not affect the normal cooling effect of the air conditioner, for example, when the air conditioner is in the cooling mode, the indoor dew point temperature and the inner pipe temperature of the air conditioner can be obtained to further determine whether condensed water is likely to be generated at the air outlet of the current air conditioner.

[0061] In step S102, when the inner tube temperature is less than or equal to the indoor dew point temperature, a target air outlet is determined from the plurality of air outlets.

[0062] In this step, when the inner tube temperature is less than or equal to the indoor dew point temperature, it indicates that condensed water may be generated at the air outlet of the air conditioner. At this time, the target air outlet can be determined from multiple air outlets of the air conditioner to ensure the normal use of the air conditioner. The air outlet may include, for example, an upper air outlet, a left air outlet, and a right air outlet. Figure 2 As shown, 11 is the left air outlet, 12 is the right air outlet, and 13 is the upper air outlet.

[0063] For example, multiple air outlet combinations can be pre-set, that is, one or more air outlets are selected from multiple air outlets, and the one or more air outlets are used as an air outlet combination, thereby obtaining multiple air outlet combinations. When the inner tube temperature is less than or equal to the indoor dew point temperature, the target air outlet combination can be determined from the multiple air outlet combinations, and the air outlet corresponding to the target air outlet combination can be used as the target air outlet. For example, the switching order of multiple air outlets can be pre-set, and the target air outlet can be determined from the multiple air outlet combinations according to the switching order. If the current air outlet combination is A, according to the preset switching order, the next air outlet combination of the air outlet combination A can be determined as combination B, and the air outlet corresponding to combination B can be used as the target air outlet.

[0064] In addition, considering that users have different requirements for the wind sensation of the air conditioner in different scenarios, in some embodiments, multiple air outlet combinations corresponding to different air outlet modes can be set. When determining the target air outlet, the air outlet mode currently corresponding to the air conditioner can be obtained first; when the inner tube temperature is less than or equal to the indoor dew point temperature, the target air outlet is determined from the multiple air outlets according to the air outlet mode. The air outlet mode can include, for example but not limited to: upward wind mode, downward pressure wind mode, left wind mode, right wind mode and forward wind mode.

[0065] For example, taking the case where the air outlet of the air conditioner includes a left air outlet, a right air outlet and an upper air outlet, and the air outlet modes include an upward wind mode, a downward pressure wind mode, a left wind mode, a right wind mode and a forward wind mode, when the air outlet mode includes the upward wind mode, the corresponding air outlet combination may include combination A1 (upper air outlet) and combination B1 (left air outlet and right air outlet); when the air outlet mode includes the downward pressure wind mode, the corresponding air outlet combination may include combination A2 (upper air outlet) and combination B2 (left air outlet and right air outlet); when the air outlet mode includes the left wind mode, the corresponding air outlet combination may include combination A3 (upper air outlet) and combination B3 (left air outlet); when the air outlet mode includes the right wind mode, the corresponding air outlet combination may include combination A4 (upper air outlet) and combination B4 (right air outlet); when the air outlet mode includes the forward wind mode, the corresponding air outlet combination may include combination A5 (upper air outlet) and combination B5 (left air outlet and right air outlet).

[0066] In step S103, the current air outlet of the air conditioner is switched to the target air outlet, and the air conditioner is controlled to discharge air through the target air outlet.

[0067] After determining the target air outlet, the air conditioner is switched from the current air outlet to the target air outlet, so that the remaining air outlets can be given a certain amount of time to volatilize the condensed water at the air outlet. After switching to the target air outlet and running for a certain period of time, it is also possible to switch to other air outlets to allow the target air outlet time to volatilize the condensed water. Specifically, after switching to the target air outlet and running for a preset time, steps S101 to S103 can be re-executed to achieve cyclic switching, thereby improving the condensation situation at the air outlet. In the case of multiple air outlet combinations, multiple air outlets can be switched in sequence according to a preset switching order, so that the same or similar air outlet effects can be achieved through different air outlet combinations.

[0068] In some embodiments, considering that the user has set a corresponding air outlet mode, in this step, the air sweeping angle of the air conditioner can also be determined according to the air outlet mode. Then, according to the air sweeping angle, the air conditioner is controlled to discharge air through the target air outlet.

[0069] For example, taking the air outlet of the air conditioner including the left air outlet, the right air outlet and the upper air outlet, and the air outlet modes including the upward wind mode, the downward pressure wind mode, the left wind mode, the right wind mode and the forward wind mode, and each air outlet having the upward and downward sweeping wind and the left and right sweeping wind functions as an example, the corresponding relationship of the following sweeping wind angles is shown:

[0070]

[0071] It can be seen from the above table that when the air outlet mode includes the upward wind mode and the target air outlet combination is combination A1, the target air outlet is the upper air outlet, and the corresponding wind sweep angle of the upper air outlet is upward sweeping up and down, and the left and right wind sweeping is centered. When the air outlet mode includes the upward wind mode and the target air outlet combination is combination B1, the target air outlet is the left air outlet and the right air outlet, and the corresponding wind sweep angles of the left air outlet and the right air outlet are both upward sweeping up and down, and the left and right wind sweeping is centered. When the air outlet mode includes the downward pressure wind mode and the target air outlet combination is combination A2, the target air outlet is the upper air outlet, and the corresponding wind sweep angle of the upper air outlet is downward sweeping up and down, and the left and right wind sweeping is centered. When the air outlet mode includes the downward pressure wind mode and the target air outlet combination is combination B2, the target air outlet is the left air outlet and the right air outlet, and the corresponding wind sweep angles of the left air outlet and the right air outlet are both downward sweeping up and down, and the left and right wind sweeping is centered. By analogy, the corresponding wind sweeping angles of other air outlet modes can be determined according to the above table, and they will not be listed here one by one.

[0072] By adopting the above method, the air conditioner has multiple air outlets. When the temperature of the inner tube of the air conditioner is less than or equal to the indoor dew point temperature, it indicates that condensed water may be generated at present. At this time, the target air outlet can be determined from the multiple air outlets, and the air can be switched to the target air outlet so that the remaining air outlets have enough time to evaporate the condensed water at the air outlet. In this way, during the cooling operation, different air outlets are switched on and off by combining them, which effectively improves the condensation situation of the air outlet without affecting the cooling effect, thereby improving the user experience.

[0073] Figure 3 is a flow chart of a method for controlling an air conditioner according to an exemplary embodiment. Figure 3 As shown, the method may include the following steps:

[0074] In step S201, the indoor dew point temperature and the inner pipe temperature of the air conditioner are acquired.

[0075] For example, when the air conditioner is in cooling mode, the indoor dew point temperature and the inner pipe temperature of the air conditioner may be acquired.

[0076] In step S202, when the duration that the inner tube temperature is less than or equal to the indoor dew point temperature is greater than or equal to the target time, a target air outlet is determined from the multiple air outlets.

[0077] The target time can be determined in any of the following two ways:

[0078] Method 1: Use the preset duration as the target time.

[0079] That is, it is possible to determine whether the inner tube temperature of the air conditioner is continuously less than or equal to the indoor dew point temperature within a preset duration, and to determine the target air outlet from the multiple air outlets when the duration for which the inner tube temperature is less than or equal to the indoor dew point temperature is greater than or equal to the preset duration.

[0080] Method 2: Obtain indoor ambient temperature and indoor ambient humidity; determine a target temperature range for the indoor ambient temperature and a target humidity range for the indoor ambient humidity; determine the target time based on the target temperature range, the target humidity range and a preset correspondence; the preset correspondence includes a correspondence between the ambient temperature range, the ambient humidity range and the time.

[0081] For example, the preset correspondence relationship may include, for example but not limited to, the following correspondence relationship table:

[0082] <![CDATA[RH 室内环境湿度 ≤a]]> <![CDATA[a<RH 室内环境湿度 ≤b]]> <![CDATA[b<RH 室内环境湿度 ]]> <![CDATA[T 内环 ≤c]]> <![CDATA[k 3 ]]> <![CDATA[k 2 ]]> <![CDATA[k 1 ]]> <![CDATA[c<T 内环 ≤d]]> <![CDATA[k 4 ]]> <![CDATA[k 3 ]]> <![CDATA[k 2 ]]> <![CDATA[d<T 内环 ]]> <![CDATA[k 5 ]]> <![CDATA[k 4 ]]> <![CDATA[k 3 ]]>

[0083] Among them, T 内环 Indicates the indoor ambient temperature, RH 室内环境湿度 Indicates indoor ambient humidity. In the table, ambient humidity b>a, ambient temperature d>c, time k 1 <k 2 <k 3 <k 4 <k 5 .

[0084] As can be seen from the above table, the target humidity range of the indoor environment humidity and the target temperature range of the indoor environment temperature can be determined by the above table. If the target humidity range of the indoor environment humidity is a<RH 室内环境湿度 ≤b, the target temperature range of the indoor ambient temperature is c<T 内环 ≤d, then from the above table, we can see that the target time is k 3 Similarly, the corresponding target time can be determined according to different target humidity ranges and target temperature ranges through the above table, which will not be listed here one by one.

[0085] Through the above method, the risk interval for generating condensation water can be divided according to the difference in indoor working conditions, that is, the difference in indoor ambient humidity and indoor ambient temperature. The greater the risk of the air conditioner generating condensation water, the shorter the corresponding target time. In this way, it is ensured that the air outlet of the air conditioner can quickly evaporate the condensation water at the air outlet by switching the air outlet.

[0086] It should be noted that the implementation method of determining the target air outlet from the multiple air outlets can refer to the above-mentioned step S103 embodiment part, which will not be repeated here.

[0087] In step S203, the current air outlet of the air conditioner is switched to the target air outlet, and the air conditioner is controlled to discharge air through the target air outlet.

[0088] Accordingly, the implementation of step S203 may refer to the embodiment of step S103, which will not be described in detail here.

[0089] In this step, after switching to the target air outlet, the process may return to step S201 to achieve cyclic switching.

[0090] Figure 4 According to an exemplary embodiment, Figure 3 The corresponding control logic schematic flow chart is as follows: Figure 4 As shown, take the air outlet combination including combination A and combination B as an example. First, after the air conditioner is turned on, it is in cooling (or dehumidification) mode, and operates according to the wind sensation (that is, the air outlet mode) and the air outlet set by the user. If the user has not set it, it can operate according to the default air outlet combination A. Then, determine whether the current air conditioner meets the anti-condensation condition. Specifically, the indoor dew point temperature and the inner tube temperature of the air conditioner can be obtained. When the inner tube temperature is less than or equal to the indoor dew point temperature, it can be determined that the current air conditioner meets the anti-condensation condition. If the anti-condensation condition is not met (that is, the inner tube temperature is greater than the indoor dew point temperature), it can continue to operate according to the current operating mode. Further, determine whether the cumulative time t when the inner tube temperature is less than or equal to the indoor dew point temperature is greater than or equal to the target time t 0 When the accumulated time t during which the inner tube temperature is less than or equal to the indoor dew point temperature is greater than or equal to the target time t 0 In the case of, if the current air outlet is combination A, switch to combination B; if the current air outlet is combination B, switch to combination A. When the cumulative time t during which the inner tube temperature is less than or equal to the indoor dew point temperature is less than the target time t 0 If the current air conditioner meets the anti-condensation condition, it returns to determine whether the current air conditioner meets the anti-condensation condition until the accumulated time t is greater than or equal to the target time t 0 Finally, after the air outlet is switched, it is possible to return to determine whether the current air conditioner meets the anti-condensation condition to achieve cyclic switching, thereby improving the condensation condition of the air outlet of the air conditioner.

[0091] Figure 5 is a flow chart of a method for controlling an air conditioner according to an exemplary embodiment. Figure 5 As shown, the method may include the following steps:

[0092] In step S301, the indoor dew point temperature and the inner pipe temperature of the air conditioner are acquired.

[0093] For example, when the air conditioner is in cooling mode, the indoor dew point temperature and the inner pipe temperature of the air conditioner may be acquired.

[0094] In step S302, the indoor environment temperature and the indoor environment humidity are obtained.

[0095] In step S303, the current indoor humidity content is determined according to the indoor environment temperature and the indoor environment humidity.

[0096] Among them, the indoor humidity content is used to characterize the current absolute humidity content in the room, that is, the moisture content in the indoor air.

[0097] For example, the current indoor humidity D may be determined according to the indoor ambient temperature and the indoor ambient humidity by the following formula:

[0098] D=f(T 内环 , RH 室内环境湿度 )=(6.11×10 5 ×RH 室内环境湿度 ×10 [(7 .5×T inner ring) / (237 .3+T内环)] )

[0099] / [461.52×(T 内环 +273.15)]-(0.04×T 内环 +2.5×RH 室内环境湿度 -0.8)

[0100] Where D represents the indoor humidity, T 内环 Indicates the indoor ambient temperature, RH 室内环境湿度 Indicates the indoor humidity.

[0101] In step S304, when the inner tube temperature is less than or equal to the indoor dew point temperature, a target air outlet is determined from the multiple air outlets according to the indoor humidity content.

[0102] In some embodiments, considering that the inner tube temperature is less than or equal to the indoor dew point temperature, it indicates that condensed water may be generated at the current air outlet of the air conditioner, but the amount of condensed water generated cannot be known. In order to more accurately control the switching of the air outlet of the air conditioner, in this step, the indoor humidity content can also be introduced. The change of the indoor humidity content can reflect the dehumidification amount to a certain extent. The greater the dehumidification amount, the more condensed water there is at the air outlet. That is, when the indoor humidity content decreases, the condensed water generated at the air outlet of the air conditioner will increase accordingly. Therefore, the amount of condensed water generated at the current air outlet of the air conditioner can be further judged by the indoor humidity content, and then the target air outlet can be determined from the multiple air outlets.

[0103] For example, the initial humidity content corresponding to the air conditioner can be obtained first. The initial humidity content can be the indoor humidity content obtained when the air conditioner switched the air outlet last time. If the initial humidity content is not recorded in the air conditioner, the current corresponding indoor humidity content can be used as the initial humidity content. Then, when the inner tube temperature is less than or equal to the indoor dew point temperature, if the difference between the initial humidity content and the indoor humidity content is greater than or equal to a preset threshold, the target air outlet is determined from the multiple air outlets.

[0104] In this way, the air outlet can be further switched according to the amount of condensed water generated. That is, by calculation, when it is determined that the amount of condensed water generated by the air outlet has accumulated to a certain value, the target air outlet can be determined from the multiple air outlets to ensure that the air outlet of the air conditioner can quickly evaporate the condensed water at the air outlet by switching the air outlet, thereby improving the accuracy of the air outlet switching.

[0105] It should be noted that the implementation method of determining the target air outlet from the multiple air outlets can refer to the above-mentioned step S103 embodiment part, which will not be repeated here.

[0106] In step S305, the current air outlet of the air conditioner is switched to the target air outlet, and the air conditioner is controlled to discharge air through the target air outlet.

[0107] Accordingly, the implementation of step S303 may refer to the embodiment of step S103, which will not be described in detail here.

[0108] In this step, after switching to the target air outlet, the current indoor humidity content can be used as the new initial humidity content, and the process returns to step S301 again to achieve cyclic switching.

[0109] Figure 6 According to an exemplary embodiment, Figure 5 The corresponding control logic schematic flow chart is as follows: Figure 6As shown, the air outlet combination includes combination A and combination B as an example. First, after the air conditioner is turned on, it is in cooling (or dehumidification) mode, and operates according to the wind feeling (i.e., air outlet mode) and the air outlet set by the user. If the user has not set it, it can operate according to the default air outlet combination A. Then, it is determined whether the current air conditioner meets the anti-condensation condition. Specifically, the indoor dew point temperature and the inner tube temperature of the air conditioner can be obtained. When the inner tube temperature is less than or equal to the indoor dew point temperature, it can be determined that the current air conditioner meets the anti-condensation condition. If the anti-condensation condition is not met (i.e., the inner tube temperature is greater than the indoor dew point temperature), it can continue to operate according to the current operation mode. Further, the current indoor real-time humidity content D2 can be determined. Specifically, the indoor real-time humidity content D2 can be determined according to the indoor ambient temperature and the indoor ambient humidity. For details, refer to the embodiment of the above step S303, which will not be repeated here. And determine the difference between the initial humidity content D1 and the current indoor real-time humidity content D2, i.e., D1-D2. Among them, the initial humidity content D1 can be the real-time indoor humidity content obtained when the air conditioner switched the air outlet last time. If the initial humidity content D1 is not recorded in the air conditioner, the current corresponding indoor humidity content D2 can be used as the initial humidity content D1. When D1-D2 is greater than or equal to the preset threshold value e, if the current air outlet is combination A, switch to combination B; if the current air outlet is combination B, switch to combination A. When D1-D2 is less than the preset threshold value e, return to determine whether the current air conditioner meets the anti-condensation condition until D1-D2 is greater than or equal to the preset threshold value e. Finally, after the air outlet is switched, the current initial humidity content D1 can be updated, and return to determine whether the current air conditioner meets the anti-condensation condition to achieve cyclic switching, thereby improving the condensation condition of the air outlet of the air conditioner.

[0110] By adopting the above method, the air conditioner has multiple air outlets. When the temperature of the inner tube of the air conditioner is less than or equal to the indoor dew point temperature, it indicates that condensed water may be generated at present. At this time, the target air outlet can be determined from the multiple air outlets, and the air can be switched to the target air outlet so that the remaining air outlets have enough time to evaporate the condensed water at the air outlet. In this way, during the cooling operation, different air outlets are switched on and off by combining them, which effectively improves the condensation situation of the air outlet without affecting the cooling effect, thereby improving the user experience.
