Thus, the present application is not intended to be limited by the

[0030] As shown in Figure 1 and Figure 7 In a first aspect, the embodiments of the present application provide an air conditioner control method, which can reduce the operation burden of the user and improve the humidification water quality and the utilization rate of the condensate water in the air conditioner. Here, the air conditioner control method comprises S10-S40.

[0031] Here, the air conditioner 1 comprises a humidification device 10, which can use indoor condensate water or water from an external water source to humidify the indoor environment. The type of the air conditioner 1 can be determined according to actual needs, and types such as wall-mounted air conditioners 1, cabinet air conditioners 1, window air conditioners 1, etc. can be used, and the embodiments of the present application do not limit this. The type of the humidification device 10 can be determined according to actual needs, and types such as atomization devices, spraying devices, etc. can be used, and the embodiments of the present application do not limit this.

[0032] S10: Determine whether the current indoor humidity is less than the set humidity.

[0033] Here, the current indoor humidity can be measured by a humidity sensor arranged on the indoor side, reflecting the relative humidity of the current indoor environment. The set humidity is the target humidity that the indoor environment is expected to reach, which can be manually input by the user or automatically generated by the air conditioner 1 according to the operating conditions such as the user's use habits, current environmental information, etc. to make the user obtain a more comfortable humidity environment.

[0034] S20: In response to determining that the current indoor humidity is less than the set humidity, determine whether the current indoor air quality is better than the air quality threshold.

[0035] When the current indoor humidity is less than the set humidity, it indicates that the current indoor environment needs to be humidified. At this time, the appropriate humidification water source can be selected according to the current indoor air quality to obtain the required water from the humidification water source, and then use these water to humidify the indoor environment.

[0036] Here, the current indoor air quality can be measured by an air quality sensor arranged on the indoor side; the type of the air quality sensor can be determined according to actual needs, and can include one or more of, for example, a VOC air sensor, a PM2.5 pollutant sensor, a carbon dioxide sensor, and the like, and the embodiments of the present application do not limit this. The air quality threshold is a threshold parameter for measuring the pros and cons of the current indoor air quality, and can be pre-set in the air conditioner 1; for example, the air quality threshold at least includes a PM2.5 content threshold in the indoor air. By comparing the current indoor air quality with the air quality threshold, the pros and cons of the current indoor air quality can be determined; if the current indoor air quality is above the air quality threshold, it indicates that the current indoor air quality is better; if the current indoor air quality is below the air quality threshold, it indicates that the current indoor air quality is poor.

[0037] S30: In response to determining that the current indoor air quality is better than the air quality threshold, the humidifying device 10 is controlled to use the indoor side condensate water to humidify the indoor environment.

[0038] When it is determined that the current indoor air quality is better than the air quality threshold, it indicates that the current indoor air quality is better, and the water quality of the condensate water released by the current indoor air when passing through the indoor heat exchanger is better, and the impurities and precipitates contained in the indoor side condensate water are better than the water from the external water source such as tap water. At this time, the humidifying device 10 can be controlled to use the indoor side condensate water to humidify the indoor environment, on the one hand, the condensate water can be fully utilized for humidification, avoiding the cumbersome operation of manually adding water for humidification by the user, on the other hand, the indoor side condensate water with better water quality can be used as water for humidification, reducing the risk of scale and even damage of the humidifying device 10 due to impurities and precipitates in the water.

[0039] S40: In response to determining that the current indoor air quality is worse than the air quality threshold, the humidifying device 10 is controlled to use water from an external water source to humidify the indoor environment.

[0040] When it is determined that the current indoor air quality is worse than the air quality threshold, it indicates that the current indoor air quality is not good, and the water quality of the condensate water released by the current indoor air when passing through the indoor heat exchanger is not ideal, and the indoor side condensate water can contain more impurities and precipitates, and the water quality thereof can be poorer than the water from the external water source such as tap water. At this time, the humidifying device 10 can be controlled to use water from an external water source to humidify the indoor environment, so that water with better water quality can be selected as humidification water.

[0041] The air conditioner control method provided in the embodiments of the present application can effectively reduce the operation burden of the user and improve the humidification water quality and the utilization rate of the condensate water in the air conditioner 1.

[0042] In some embodiments, the air conditioner 1 can include a fresh air module 80; when the fresh air module 80 is turned on, the fresh air module 80 can introduce outdoor fresh air into the indoor environment. As shown in FIG. 1, after it is determined that the current indoor air quality is better than the air quality threshold, in addition to controlling the humidification device 10 to use the indoor side condensate water to humidify the indoor environment, the air conditioner control method can further include S50-S60. Figure 2

[0043] S50: Determine whether the current outdoor air quality is better than the current indoor air quality. Here, the current outdoor air quality can be measured by the air quality sensor arranged on the indoor side; or, the outdoor air quality data of the local area can also be obtained through the network, which is used as the current outdoor air quality. By comparing the current outdoor air quality and the current indoor air quality, it can be determined which one is better.

[0044] S60: In response to determining that the current outdoor air quality is better than the current indoor air quality, control the fresh air module 80 to be turned on.

[0045] When it is determined that the current outdoor air quality is better than the current indoor air quality, it indicates that the current outdoor air quality is better; at this time, the fresh air module 80 can be controlled to be turned on to introduce outdoor fresh air into the indoor environment, thereby improving the air quality of the indoor environment and making the current indoor air quality rise accordingly. Thanks to the rise of the current indoor air quality, the water quality of the condensate water released by the indoor air with higher cleanliness when passing through the indoor heat exchanger is better, which can further improve the water quality of the indoor side condensate water, thereby further improving the humidification water quality and reducing the risk of damage to the humidification device 10 due to impurities and precipitates in the water.

[0046] ​By setting S50 to S60, the fresh air module 80 can be turned on when the outdoor air is relatively clean. The outdoor fresh air is used to improve the air quality of the indoor environment and the water quality of the indoor condensate, which greatly improves the comfort of indoor users and reduces the risk of scale buildup and damage to the humidifier 10 due to impurities and sediments in the water.

[0047] like Figure 3 As shown, in some examples, S60 can be S60'.

[0048] S60': Controls the humidification device 10 to humidify the indoor environment using both indoor and outdoor condensate.

[0049] When the outdoor air quality is better than the indoor air quality, the condensate released when outdoor air passes through the outdoor heat exchanger (i.e., the outdoor condensate) is also of better quality. In this case, in addition to introducing fresh outdoor air into the indoor environment, the outdoor condensate can be used as a humidification source, combining both indoor and outdoor condensate to humidify the indoor environment. This significantly improves the quality and volume of humidification water, further reducing the depletion of condensate and the resulting inconvenience of frequent manual refilling. It also reduces the risk of damage to the humidification device 10 due to impurities and sediment in the water.

[0050] like Figure 2 or Figure 3 As shown, in some examples, the air conditioner control method may also include S70.

[0051] S70: In response to determining that the current outdoor air quality is worse than the current indoor air quality, control the air conditioner 1 to discharge or purify the outdoor condensate.

[0052] When the current outdoor air quality is determined to be worse than the current indoor air quality, it indicates that the outdoor condensate is of lower quality than the indoor condensate. In this case, the outdoor condensate can be directly discharged outside the air conditioner 1, for example, to a drain, to avoid the poor-quality outdoor condensate remaining and causing pollution. Alternatively, a purification device can be installed in the air conditioner 1 to purify the outdoor condensate. After the cleanliness of the outdoor condensate is improved to an ideal level, the purified outdoor condensate can be used as humidification water. Or, even when the current outdoor air quality is worse than the current indoor air quality, but the current outdoor air quality is better than the air quality threshold, the outdoor condensate can still be used as humidification water.

[0053] like Figure 7As shown, in some embodiments, the air conditioner 1 can include an indoor side water collecting tray 20 and a water storage tank 30; the indoor side water collecting tray 20 is used to collect indoor side condensate water, for example, can be arranged below the indoor heat exchanger; the water storage tank 30 is used to store water from an external water source, and the user can manually add water from the external water source, for example, tap water, into the water storage tank 30. The humidifying device 10 can include a humidifying water tank connected with the indoor side water collecting tray 20 and the water storage tank 30 respectively, to obtain water for humidification from the indoor side water collecting tray 20 and / or the water storage tank 30.

[0054] As shown, here, S30 can include S31, in order to achieve the purpose of using indoor side condensate water for humidification. Figure 4

[0055] S31: control the humidifying water tank and the indoor side water collecting tray 20 to be connected, and control the humidifying water tank and the water storage tank 30 to be disconnected.

[0056] In this way, the humidifying water tank can only obtain water for humidification from the indoor side water collecting tray 20, and cannot obtain water for humidification from the water storage tank 30, so as to control the humidifying water source to be indoor side condensate water. In some examples, a shut-off valve 50 can be arranged between the humidifying water tank and the indoor side water collecting tray 20, and between the humidifying water tank and the water storage tank 30 respectively, and the water path between the humidifying water tank and the indoor side water collecting tray 20 and the water path between the humidifying water tank and the water storage tank 30 can be controlled by opening and closing the shut-off valve 50.

[0057] Here, S40 can include S41, in order to achieve the purpose of using water from an external water source for humidification.

[0058] S41: control the humidifying water tank and the indoor side water collecting tray 20 to be disconnected, and control the humidifying water tank and the water storage tank 30 to be connected.

[0059] In this way, the humidifying water tank can only obtain water for humidification from the water storage tank 30, and cannot obtain water for humidification from the indoor side water collecting tray 20, so as to control the humidifying water source to be water from an external water source.

[0060] As shown, here, S30 can include S31, in order to achieve the purpose of using indoor side condensate water for humidification. Figure 7 ​As shown, in some examples, the air conditioner 1 can further include an outdoor water pan 40. The outdoor water pan 40 is used to collect indoor condensate water, for example, can be arranged below the outdoor heat exchanger, and the humidification water tank can be connected with the outdoor water pan 40. In this way, when it is needed to use the outdoor condensate water for humidification, the humidification water tank and the outdoor water pan 40 can be controlled to be connected, so that the water in the outdoor water pan 40 can flow into the humidification water tank; and when it is not needed to use the outdoor condensate water for humidification, the humidification water tank and the outdoor water pan 40 can be controlled to be disconnected, so as to prevent the water in the outdoor water pan 40 from flowing into the humidification water tank. In some examples, a stop valve 50 can be arranged between the humidification water tank and the outdoor water pan 40, and the water path between the humidification water tank and the outdoor water pan 40 is controlled by opening and closing the stop valve 50.

[0061] As shown in FIG. 1, in some embodiments, the specific steps of controlling the humidification device 10 to humidify the indoor environment can include S301-S303. Figure 5

[0062] S301: Obtain the volume of the indoor space.

[0063] Here, the volume of the indoor space can be measured by a laser range finder or other measuring device to determine the volume of the indoor space.

[0064] S302: Determine the target humidification amount of the humidification device 10 according to the volume of the indoor space, the current indoor humidity, and the set humidity.

[0065] Here, the difference between the current indoor humidity and the set humidity can be calculated, and then the required humidification amount can be determined according to the product of the difference and the volume of the indoor space, and the product is taken as the target humidification amount of the humidification device 10.

[0066] S303: Control the humidification device 10 to use indoor condensate water or water from an external water source for humidification according to the target humidification amount.

[0067] Based on the target humidification amount, the humidification process of the humidification device 10 can be quantitatively controlled, and the humidification amount provided by the humidification device 10 matches the required humidification amount, avoiding obvious deviation between the indoor humidity after humidification and the set humidity, thereby ensuring the use comfort of the indoor user.

[0068] As shown in FIG. 1, in some embodiments, S40 can further include S42. Figure 6

[0069] S42: In response to determining that the current indoor air quality is worse than the air quality threshold, control the air conditioner 1 to discharge or purify the indoor condensate water.

[0070] ​​When it is determined that the current outdoor air quality is worse than the current indoor air quality, it indicates that the current indoor air quality is not good. At this time, in addition to using the water from the external water source to humidify the indoor environment, the indoor side condensate water can also be treated as necessary. Here, the indoor side condensate water can be directly discharged outside the air conditioner 1, for example, to a sewer, to avoid the indoor side condensate water with poor water quality remaining and causing pollution; or a purification device can also be provided in the air conditioner 1, and the indoor side condensate water is purified by the purification device, and after the cleanliness of the indoor side condensate water is improved to a desired degree, the indoor side condensate water after the purification treatment is used as humidification water.
