Technical Field

[0001] This application relates to the field of smart home appliance technology, for example to a control method, apparatus, air conditioner, and readable storage medium for an air conditioner. Background Technology

[0002] To improve users' sleep quality, related technologies collect information such as users' sleeping posture and breathing patterns to determine their sleep state and combine this with the sleep mode of the air conditioner to provide users with a comfortable environment.

[0003] In implementing the disclosed embodiments, there is an error in judging the user's sleep state, which causes the air conditioner's operating mode to fail to meet the user's physical needs and affects the user's experience. Summary of the Invention

[0004] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0005] This disclosure provides a control method, apparatus, air conditioner, and readable storage medium for an air conditioner. By employing the control method provided by this disclosure, the accuracy of determining a user's sleep stage can be improved.

[0006] In some embodiments, a control method for an air conditioner is provided, the control method comprising: acquiring brainwave information of a user; determining the user's sleep stage based on the brainwave information; and controlling the operation of the air conditioner based on the sleep stage.

[0007] The air conditioner control method provided in this disclosure collects the user's electroencephalogram (EEG) information. By analyzing the EEG information, the user's current sleep stage is determined. The air conditioner is then controlled according to the operating parameters corresponding to the current sleep stage. This ensures that the indoor environmental parameters meet the user's physiological needs during sleep, thereby improving the user experience and sleep quality. By using EEG information to determine sleep state, the user's physiological parameters can be directly obtained, thus improving the accuracy of sleep stage determination.

[0008] Optionally, the sleep stage includes a deep sleep stage. Based on the user being in the deep sleep stage, the step of controlling the operation of the air conditioner according to the sleep stage includes: determining the human comfort index of the indoor environment; obtaining the installation height of the air conditioner; correcting the human comfort index according to the installation height to obtain a target comfort index; and controlling the operation of the air conditioner according to the target comfort index.

[0009] In this embodiment, deep sleep refers to the user entering a deep sleep state, during which the user is not easily awakened. This disclosure achieves air conditioner operation control based on the adjusted target comfort index by modifying the human comfort index of the indoor environment. Controlling the air conditioner operation by the target comfort index ensures that indoor environmental parameters align with the user's physical needs, thereby improving the user's physical comfort. By providing a comfortable indoor environment and extending the duration of deep sleep, the user's sleep quality can be improved.

[0010] Optionally, the step of controlling the operation of the air conditioner according to the target comfort index includes: adjusting the initial set temperature of the air conditioner to the target set temperature according to the target comfort index; and controlling the operation of the air conditioner according to the target set temperature.

[0011] In this embodiment, the initial set temperature is adjusted according to the target comfort index to obtain the target set temperature. The target set temperature meets the user's physical needs, thereby improving the user's comfort. The air conditioner is controlled to operate according to the target set temperature so that the indoor ambient temperature reaches the target set temperature, thus meeting the user's current comfort needs and extending the user's deep sleep duration.

The step of controlling the operation of the air conditioner according to the sleep stage includes: based on the user being in the light sleep stage, controlling the operating frequency of the compressor to be reduced to a minimum operating frequency, the rotation speed of the indoor fan to be reduced to a first preset speed, and keeping the swing angle of the air outlet louver at 0 degrees.

[0019] In this embodiment, when the user is in a light sleep stage, they are easily awakened and require a relatively quiet and comfortable indoor environment. This disclosure reduces noise by lowering the compressor's operating frequency to a minimum, reducing the indoor fan speed to a first preset speed, and maintaining the oscillation angle of the air outlet blades at 0 degrees. By reducing the air conditioner's noise, the quietness of the indoor environment is improved. Furthermore, by maintaining the operating mode, the indoor temperature can be continuously adjusted to meet the user's comfort needs.

The step of controlling the operation of the air conditioner according to the sleep stage includes: determining the target operating frequency of the compressor based on the outdoor ambient temperature, based on the user being in the transition sleep stage; controlling the compressor to operate at the target operating frequency; and controlling the speed of the indoor fan to increase to a second preset speed; wherein the first preset speed is less than the second preset speed.

[0021] In this embodiment, the transitional sleep stage lies between light sleep and deep sleep, requiring a quiet and comfortable indoor environment. This disclosure determines the compressor's operating frequency based on the outdoor environment and increases the indoor fan speed to a second preset speed to quickly reach the user's set temperature. The second preset speed corresponds to a low fan speed, achieving airflow while reducing indoor noise.

The target temperature setting should be equal to the initial temperature setting minus the third preset value. For a comfort level of 7, if the perceived temperature is warm, the initial temperature setting should be lowered. The target temperature setting should be equal to the initial temperature setting minus the fourth preset value. For a comfort level of 8, if the perceived temperature is very hot, the initial temperature setting should be lowered. The target temperature setting should be equal to the initial temperature setting minus the fifth preset value.
