The above-mentioned first preset time and second preset time can be 30 minutes or 1 hour, and the user can adjust the specific duration according to different situations.

Optionally, before the control method for the air conditioner is used for temperature and humidity regulation, it also includes: judging whether the input intermittent automatic temperature control instruction is obtained, and only if the input intermittent automatic temperature control instruction is obtained, then judge Whether the current indoor ambient humidity is in the appropriate humidity range, that is, the control method of the present invention can determine whether to execute based on the user's choice, that is, the air conditioner will perform the above-mentioned step S1 only when the user inputs an intermittent self-control temperature command to the air conditioner, and In the following steps, if the user does not input the intermittent self-temperature control command to the air conditioner, the air conditioner does not execute the intermittent self-temperature control mode. A manner for the user to input instructions may be remote control input or voice input. Of course, in practical applications, the air conditioner can also determine whether to execute the intermittent self-control temperature mode by itself.

S2: continue to judge whether the current indoor environment humidity is in the appropriate humidity range, if yes, execute step S21, if not, execute step S22;

Optionally, the above-mentioned third preset time and fourth preset time can be 15 minutes and 30 minutes, or 1 hour, and the user can adjust the specific duration according to different situations.

Optionally, users can flexibly set the preset temperature according to different needs and specific seasons, for example, the preset temperature range in summer can be 23°C-28°C, and the preset temperature range in winter can be 18°C-25°C Of course, the above-mentioned preset temperature range is just an example. In actual implementation, the preset temperature can be adjusted flexibly. There is no limit to the value of the specific preset temperature, as long as it can meet the suitable temperature of the human body. In the present invention, the preset temperature in the cooling mode is represented by the first temperature threshold, and the preset temperature in the heating mode is represented by the second temperature threshold, and both the first temperature threshold and the second temperature threshold can be set by user input , the input method can be remote control input or voice input, etc.

The control method of the present invention will be specifically described below according to two situations of the heat exchange mode of the air conditioner. When the current outdoor temperature is high, such as summer or autumn, the heat exchange mode of the air conditioner is the cooling mode, and the preferred preset indoor ambient humidity range can be 50%RH-60%RH. The above preset humidity range is only For example, in specific implementation, users in different regions can make adjustments according to different weather and usage needs. The first preset time and the second preset time of the cooling and humidity adjustment of the air conditioner can be the same or different. If the first preset time and the second preset time are the same, both can be set to 30 minutes or 1 hour, if the first preset time and the second preset time are different, the first preset time can be set to 30 minutes , the second preset time is set to 1 hour, and the user can adjust it according to individual needs and specific temperature. Referring to Figure 2, preferably, the control method specifically includes the following steps:

S110: When the air conditioner is in cooling mode, it is judged whether the current indoor ambient humidity is 50%RH-60%RH, if yes, execute step S111, if not, execute step S112;

S111: The air conditioner only cools for 1 hour;

S112: The air conditioner refrigerates and adjusts the humidity for 1 hour;

For example, when the indoor ambient humidity is higher than the preset humidity range, the air conditioner can continuously remove water vapor from the indoor environment, that is, dehumidify while cooling the indoor temperature through the indoor heat exchanger. Turn on the dehumidification element, and when the indoor ambient humidity is lower than the preset humidity range, the air conditioner will humidify the indoor environment by activating the humidifying element. After the air conditioner has refrigerated and adjusted the humidity for 1 hour, continue to judge whether the current indoor ambient humidity is between 50%RH and 60%RH, the third preset time and the fourth preset time for air supply, cooling and humidity adjustment of the air conditioner can be be the same or different, if the third preset time and the fourth preset time are the same, both can be set to 30 minutes or 1 hour, if the third preset time and the fourth preset time are not the same, you can The third preset time is set to 30 minutes, and the fourth preset time is set to 1 hour. The user can adjust it according to individual needs and specific temperature. Preferably, continue to perform the following steps:

S120: continue to judge whether the current indoor environment humidity is 50%RH-60%RH, if yes, execute step S121, if not, execute step S122;

S121: The air conditioner only supplies air and does not cool for 30 minutes;

S122: The air conditioner does not cool the air and adjust the humidity for 30 minutes;

Exemplarily, the first temperature threshold can be set to 23°C-28°C, and users in different regions can set it according to local climate and personal needs. Preferably, the first temperature threshold in this embodiment is 26°C. Of course, The above-mentioned first temperature threshold is just an example, and the indoor first temperature threshold in regions with extreme environments may be flexibly adjusted according to different situations. The suitable temperature in summer is 23°C-28°C. In this preferred embodiment, the first temperature threshold is set to 26°C. When the air conditioner finishes cooling within 1 hour, the indoor ambient temperature will start to rise. The upper limit of the suitable temperature in this season is 28°C with a temperature recovery space of 2°C, that is, the subsequent indoor temperature has a buffer temperature of 2°C to reach the highest value of the suitable temperature, so that the air conditioner can keep the temperature and humidity at the same time to avoid the air conditioner. Continuous temperature and humidity control wastes energy, saves resources, and improves user comfort.

The fifth preset time and the sixth preset time of the air supply, cooling and humidity adjustment of the air conditioner can be the same or different, if the fifth preset time and the sixth preset time are the same, both can be set 30 minutes or 1 hour, if the fifth preset time is different from the sixth preset time, the fifth preset time can be set to 30 minutes, the sixth preset time can be set to 1 hour, the air supply of the air conditioner, The seventh preset time and the eighth preset time of cooling and humidity control can be the same or different. If the seventh preset time and the eighth preset time are the same, they can both be set to 15 minutes or 30 minutes , if the seventh preset time is not the same as the eighth preset time, the seventh preset time can be set to 15 minutes, and the eighth preset time can be set to 30 minutes, and the user can adjust it according to individual needs and specific temperature, preferably , continue with the following steps:

S130: judging whether the current indoor ambient temperature reaches 26°C and whether the current indoor ambient humidity is within 50%RH-60%RH;

S131: If the current indoor ambient temperature is greater than or equal to 26°C and the current indoor ambient humidity is 50%RH-60%RH, the air conditioner only cools for 30 minutes and then returns to step S120;

S132: If the current indoor ambient temperature is greater than or equal to 26°C and the current indoor ambient humidity is not between 50%RH-60%RH, the air conditioner cools and adjusts the humidity for 30 minutes, then returns to step S120;

S133: If the current indoor ambient temperature is less than 26°C and the current indoor ambient humidity is 50%RH-60%RH, the air conditioner only supplies air without cooling for 15 minutes and then returns to step S130;

S134: If the current indoor ambient temperature is less than 26°C and the current indoor ambient humidity is not between 50%RH-60%RH, the air conditioner does not supply air and adjusts the humidity for 15 minutes, then returns to step S130.

It should be noted that the first temperature threshold value of 26°C is only a specific preferred method, and it can also be adjusted in practical applications. For example, the first temperature threshold value can be set to 24°C or 27°C, etc. At the same time, the above The preset time of refrigeration, air supply and humidity control is only a specific setting method, and it can also be adjusted in practical applications. For example, the preset time can be set to 40 minutes or 1 hour. Taking the first temperature threshold as 26°C as an example, when the current indoor ambient temperature is 24°C and the humidity is not within 50%RH-60%RH, the air conditioner will not cool the air and adjust the humidity for 15 minutes, then return to step S130. When the indoor ambient temperature is 28°C and the humidity is not within 50%RH-60%RH, the air conditioner cools and adjusts the humidity for 30 minutes and then returns to step S120.

When the current outdoor temperature is low, such as winter or spring, the heat exchange mode of the air conditioner is the heating mode, and the preferred preset indoor ambient humidity range can be 40%RH-50%RH, the above preset humidity range It is just an example. In actual implementation, users in different regions can adjust according to different weather and usage needs. The first preset time and the second preset time of the air conditioner’s heating and humidity adjustment can be the same or different. Yes, if the first preset time and the second preset time are the same, both can be set to 30 minutes or 1 hour; if the first preset time and the second preset time are different, the first preset time can be set to 30 minutes, the second preset time is set to 1 hour, the user can adjust it according to individual needs and specific temperature, referring to Figure 2, preferably, the control method specifically includes the following steps:

S210: When the air conditioner is in the heating mode, determine whether the current indoor ambient humidity is between 40%RH-50%RH, if yes, execute step S211, if not, execute step S212;

S211: The air conditioner only heats for 1 hour;

S212: The air conditioner heats up and adjusts the humidity for 1 hour;

For example, when the indoor ambient humidity is higher than the preset humidity range, the air conditioner can continuously remove water vapor from the indoor environment through the dehumidification element, that is, dehumidify; when the indoor ambient humidity is lower than the preset humidity range, The air conditioner humidifies the indoor environment by activating the humidifying element. After the air conditioner heats and adjusts the humidity for 1 hour, continue to judge whether the current indoor ambient humidity is between 40%RH-50%RH, the third preset time and the fourth preset time for the air supply, heating and humidity adjustment of the air conditioner The time can be the same or different. If the third preset time and the fourth preset time are the same, they can both be set to 30 minutes or 1 hour. If the third preset time and the fourth preset time are not the same , the third preset time can be set to 30 minutes, and the fourth preset time can be set to 1 hour. The user can adjust it according to individual needs and specific temperature. Preferably, continue to perform the following steps:

S220: continue to judge whether the current indoor environment humidity is between 40%RH-50%RH, if yes, execute step S221, if not, execute step S222;

S221: The air conditioner only supplies air but does not heat for 30 minutes;

S222: The air conditioner does not heat the air and adjusts the humidity for 30 minutes;

Exemplarily, the second temperature threshold can be set to 18°C-25°C, and users in different regions can set it according to local climate and personal needs. Preferably, the second temperature threshold in this embodiment is 20°C. Of course, The above-mentioned second temperature threshold is just an example, and the indoor second temperature threshold in regions with extreme environments may be flexibly adjusted according to different situations. The suitable temperature in winter is 18°C-25°C. In this preferred embodiment, the second temperature threshold is set to 20°C. When the air conditioner finishes heating within 1 hour, the indoor ambient temperature will start to drop, and the distance between 20°C and the human body The lower limit of the suitable temperature in this season is 18°C with a temperature return space of 2°C, that is, the subsequent indoor temperature has a buffer temperature of 2°C to reach the lowest value of the suitable temperature, so that the air conditioner can keep the temperature and humidity while avoiding the air conditioner. The energy consumption of continuous temperature and humidity control of the device is wasted, saving resources and improving the user's comfort experience.

The fifth preset time and the sixth preset time for the air supply, heating and humidity adjustment of the air conditioner can be the same or different. If the fifth preset time and the sixth preset time are the same, they can both be the same. Set it to 30 minutes or 1 hour. If the fifth preset time is different from the sixth preset time, you can set the fifth preset time to 30 minutes and the sixth preset time to 1 hour. . The seventh preset time and the eighth preset time of heating and humidity control can be the same or different. If the seventh preset time and the eighth preset time are the same, they can both be set to 15 minutes or 30 minutes, if the seventh preset time is different from the eighth preset time, you can set the seventh preset time to 15 minutes, and the eighth preset time to 30 minutes, the user can adjust according to individual needs and specific temperature , preferably proceed with the following steps:

S230: judging whether the current indoor ambient temperature reaches 20°C and whether the current indoor ambient humidity is in the range of 40%RH-50%RH;

S231: If the current indoor ambient temperature is less than or equal to 20°C and the current indoor ambient humidity is 40%RH-50%RH, the air conditioner only heats for 30 minutes and then returns to step S220;

S232: If the current indoor ambient temperature is less than or equal to 20°C and the current indoor ambient humidity is not between 40%RH-50%RH, the air conditioner heats and adjusts the humidity for 30 minutes and then returns to step S220;

S233: If the current indoor ambient temperature is greater than 20°C and the current indoor ambient humidity is between 40%RH-50%RH, the air conditioner only supplies air without heating for 15 minutes and then returns to step S230;

S234: If the current indoor ambient temperature is greater than 20°C and the current indoor ambient humidity is not between 40%RH-50%RH, the air conditioner does not supply air to heat and adjust the humidity for 15 minutes, then return to step S230.

It should be noted that the second temperature threshold value of 20°C is only a specific preferred method, which can also be adjusted in practical applications, such as the second temperature threshold value can be set to 19°C or 21°C, etc. At the same time, the above The preset time of heating, air supply and humidity adjustment is only a specific setting method, and it can also be adjusted in practical applications. For example, the preset time can be set to 40 minutes or 1 hour, etc., depending on the second Take the temperature threshold of 20°C as an example. When the current indoor ambient temperature is 23°C and the humidity is not within 40%RH-50%RH, the air conditioner will not heat the air and adjust the humidity for 15 minutes, then return to step S230. The current indoor environment When the temperature is 18°C and the humidity is not within 40%RH-50%RH, the air conditioner will heat and adjust the humidity for 30 minutes and then return to step S220.
