[0030] Reselecting the target sleep curve according to the third comparison result includes:

[0031] The sleep curve with the target human body temperature having the largest body temperature difference is selected as the new target sleep curve.

When there are multiple sleepers, the ambient temperature and the target temperature at the same sleep time and time point in each sleep curve are compared to obtain a first comparison result, and the target sleep curve is selected according to the first comparison result, so that the air conditioner operates according to the target sleep curve, which can take into account the comfort of each person when sleeping as much as possible and avoid the situation where one person feels extremely uncomfortable with the sleeping temperature.

[0046] Furthermore, the ambient temperature difference between the ambient temperature and the target temperature at the same sleep time and time point in each sleep curve is calculated. For example, if the ambient temperature is 30 degrees, the target temperature at the same sleep time and time point in one sleep curve is 28 degrees, the target temperature at the same sleep time and time point in another sleep curve is 27 degrees, and the target temperature at the same sleep time and time point in another sleep curve is 25 degrees; ambient temperature differences of 2 degrees, 3 degrees, and 5 degrees can be obtained, respectively. The sleep curve with the target temperature corresponding to the largest ambient temperature difference is selected as the target sleep curve, that is, the sleep curve with a target temperature of 25 degrees corresponding to 5 degrees can be selected as the target sleep curve. This embodiment selects the sleep curve of the person who feels the most uncomfortable with the ambient temperature (the one with the largest ambient temperature difference) as the target sleep curve to prevent this person from being unable to fall asleep, thereby ensuring that every sleeping person can fall asleep smoothly as much as possible, and ensuring everyone's comfort from the overall perspective.

[0047] Furthermore, the target body temperature of a specified human body at different sleeping times is obtained, the target temperature corresponding to the target body temperature is calculated, and the correspondence between the target body temperature and the target temperature at different sleeping times is obtained to form a sleep curve. Sleep curves for naps, night sleep, and any other sleeping times can be formed, so that the sleep mode can be adjusted according to the user's sleep at different times. It is highly targeted and is conducive to improving people's sleep comfort.

[0048] Based on the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will become more aware of the above and other objects, advantages and features of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Hereinafter, some specific embodiments of the present invention will be described in detail in an exemplary and non-limiting manner with reference to the accompanying drawings. The same reference numerals in the accompanying drawings indicate the same or similar components or parts. It should be understood by those skilled in the art that these drawings are not necessarily drawn to scale. In the accompanying drawings:

[0052] Figure 3 FIG. 1 is a structural diagram of an air conditioner according to an embodiment of the present invention. DETAILED DESCRIPTION

[0053] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0054] Figure 1 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention. The method generally includes the following steps S102 to S112 .

[0055] Step S102: Obtaining a sleep mode start instruction and a time point of the start instruction for the air conditioner.

[0056] Step S104: In response to the start instruction, the number of sleeping people in the environment where the air conditioner is located is obtained.

[0057] Step S106: Obtain the sleep curve corresponding to each of the pre-defined sleepers at a specific time point. The sleep curve may include the sleep time and the corresponding target temperature.

[0058] In this step, the target temperature is the temperature to which the ambient temperature needs to be adjusted. For example, if the time point is 12 noon, indicating that the person is taking a nap, then the sleep curve for the nap needs to be obtained, and the sleep curve for the sleep time at 12 noon needs to be obtained; if the time point is 10 pm, then the sleep curve for the night needs to be obtained, and the sleep curve for the sleep time at 10 pm needs to be obtained. This step can obtain corresponding sleep curves for different sleep scenarios of the user, improving the pertinence of the obtained sleep curves and helping to improve the user's comfort.

[0059] Step S108: Obtain the ambient temperature of the environment where the air conditioner is located at a certain time point.

[0060] Step S110: When there are multiple sleepers, the ambient temperature is compared with the target temperature at the same sleep time and time point in each sleep curve to obtain a first comparison result.

[0061] Step S112: selecting a target sleep curve according to the first comparison result, and operating the air conditioner according to the target sleep curve.

[0062] In this embodiment, a sleep mode activation command and the time of the activation command are obtained. In response to the activation command, the number of people sleeping in the air conditioner's environment is obtained, and a pre-defined sleep curve corresponding to each of the people sleeping at that time is obtained. The sleep curve includes the sleep time and its corresponding target temperature. The ambient temperature of the air conditioner's environment at that time is obtained. If there are multiple people sleeping, the ambient temperature is compared with the target temperature at the same sleep time and time in each sleep curve to obtain a first comparison result. Based on the first comparison result, a target sleep curve is selected, and the air conditioner operates according to the target sleep curve. This maximizes the comfort of each person during sleep and avoids situations where a single person experiences extreme discomfort due to the sleeping temperature. If there is only one person sleeping, that person's sleep curve can be used as the target sleep curve.

[0063] In one embodiment of the present invention, comparing the ambient temperature with the target temperature at the same sleep time and time point in each sleep curve to obtain a first comparison result may include:

[0064] Calculate the difference between the ambient temperature and the target temperature at the same sleep time and time point in each sleep curve;

[0065] Selecting a target sleep curve according to the first comparison result may include:

[0066] The sleep curve corresponding to the target temperature with the largest ambient temperature difference is selected as the target sleep curve.

[0067] In this embodiment, the difference between the ambient temperature and the target temperature at the same sleep time and time point in each sleep curve is calculated. For example, if the ambient temperature is 30°C, the target temperature at the same sleep time and time point in one sleep curve is 28°C, the target temperature at the same sleep time and time point in another sleep curve is 27°C, and the target temperature at the same sleep time and time point in another sleep curve is 25°C; the resulting ambient temperature differences are 2°C, 3°C, and 5°C, respectively. The sleep curve with the target temperature corresponding to the largest ambient temperature difference is selected as the target sleep curve. That is, the sleep curve with a target temperature of 25°C corresponding to 5°C is selected as the target sleep curve. This embodiment selects the sleep curve of the person who is most uncomfortable with the ambient temperature (the one with the largest ambient temperature difference) as the target sleep curve to prevent this person from being unable to fall asleep, thereby ensuring that everyone who sleeps can fall asleep smoothly and ensuring overall comfort for everyone.

[0068] In one embodiment of the present invention, the sleep profile may include a target body temperature corresponding to the target temperature;

[0069] Operating the air conditioner according to the target sleep curve may include:

[0070] Obtaining the body temperature of a person corresponding to the target sleep curve;

[0071] comparing the human body temperature with the target human body temperature to obtain a second comparison result;

[0072] The target temperature corresponding to the target human body temperature is corrected according to the second comparison result.

[0073] In this embodiment, the body temperature of the person corresponding to the target sleep curve is obtained, and the body temperature is compared with the target body temperature to obtain a second comparison result. Based on the second comparison result, the target temperature corresponding to the target body temperature is corrected to avoid large fluctuations in the body temperature and ensure the comfort of the person. Generally, the body temperature of the person corresponding to the target sleep curve can be obtained at various time points during sleep by infrared, and then the body temperature at each time point can be compared with the target body temperature at the same time point.

[0074] In one embodiment of the present invention, correcting the target temperature corresponding to the target human body temperature according to the second comparison result may include:

[0075] When the human body temperature is greater than the target human body temperature, the target temperature is lowered;

[0076] When the human body temperature is lower than the target body temperature, the target temperature is increased.

[0077] In this embodiment, when the human body temperature is higher than the target human body temperature, it means that the human body feels hotter, and it is necessary to adjust the operating parameters of the air conditioner to lower the target temperature, such as lowering the frequency of the compressor or reducing the air supply volume to prevent the human body from overheating; when the human body temperature is lower than the target human body temperature, it means that the human body feels cooler, and it is necessary to adjust the operating parameters of the air conditioner to increase the target temperature, such as increasing the frequency of the compressor or increasing the air supply volume to prevent the human body from being too cool and ensure the comfort of the human body.

[0078] In one embodiment of the present invention, after selecting a target sleep curve according to the first comparison result and operating the air conditioner according to the target sleep curve, the method may include:

[0079] Obtaining each person's body temperature;

[0080] Comparing the body temperature of each person with the target body temperature in the corresponding sleep curve to obtain a third comparison result;

[0081] The target sleep curve is reselected according to the third comparison result.

[0082] In this embodiment, considering that a person's body temperature may change significantly during sleep, it indicates that the person may feel uncomfortable. To reduce the occurrence of this situation, the body temperature of each person is obtained, and each person's body temperature is compared with the target body temperature in the corresponding sleep curve to obtain a third comparison result, and the target sleep curve is reselected based on the third comparison result.

[0083] In one embodiment of the present invention, comparing the body temperature of each person with the target body temperature in the corresponding sleep curve to obtain a third comparison result may include:

[0084] Calculate the body temperature of each person and the temperature difference between the target body temperature in the corresponding sleep curve;

[0085] Reselecting the target sleep curve according to the third comparison result may include:

[0086] The sleep curve with the target human body temperature having the largest body temperature difference is selected as the new target sleep curve.

[0087] In this embodiment, the temperature difference between each person's body temperature and the target body temperature in the corresponding sleep curve is calculated. That is, the temperature difference between the body temperature at the same time point and the target body temperature in the corresponding sleep curve is calculated. For example, if a person's body temperature at 11 p.m. is 36.5 degrees, the corresponding target body temperature at 11 p.m. is 36.5 degrees, and the temperature difference is 0; if a person's body temperature at 11 p.m. is 36.8 degrees, the corresponding target body temperature at 11 p.m. is 36.4 degrees, and the temperature difference is 0.4; if a person's body temperature at 11 p.m. is 37.8 degrees, the corresponding target body temperature at 11 p.m. is 36.4 degrees, and the temperature difference is 1.4; if a person's body temperature at 11 p.m. is 38.8 degrees, the corresponding target body temperature at 11 p.m. is 36.4 degrees, and the temperature difference is 2.4. The sleep curve with the target body temperature with the largest temperature difference is selected as the new target sleep curve, that is, the sleep curve with a temperature difference of 2.4 and a target body temperature of 36.4 is selected as the new target sleep curve, thereby preventing the person from feeling severe discomfort.

[0088] In one embodiment of the present invention, before selecting the sleep curve with the target human body temperature having the largest body temperature difference as the new target sleep curve, the following steps may be performed:

[0089] Compare the body temperature difference with the preset threshold;

[0090] If the body temperature difference is less than the preset threshold, it means that the body temperature of each person is normal, and the sleep curve with the target body temperature with the largest body temperature difference is selected as the new target sleep curve;

[0091] If the body temperature difference is greater than or equal to the preset threshold, it means that the person's body temperature is in an abnormal state, so the air conditioner runs according to the preset temperature and outputs an alarm message.

[0092] In this embodiment, the preset threshold value can generally be any value between 0.7 and 1. The preset temperature is generally any value between 24 and 28 degrees Celsius. If the body temperature difference is greater than or equal to the preset threshold value, it indicates that the person's body temperature is abnormal. For example, in the above embodiment, if the body temperature difference is 2.4, it is greater than the preset threshold value and is abnormal. The air conditioner is operated at the preset temperature to prevent the person's body temperature from being too high, and an alarm message is output to wake the person up so that timely treatment measures can be taken to ensure the person's health.

[0093] In one embodiment of the present invention, the sleep curve can be formulated in the following manner:

[0094] Get the start instruction for making a sleep curve and enter the sleep curve collection mode;

[0095] Obtain the target body temperature of a specified human body at different sleep moments;

[0096] The target temperature corresponding to the target human body temperature is calculated, and the corresponding relationship between the target human body temperature and the target temperature at different sleeping moments is obtained to form a sleep curve.

[0097] In this embodiment, infrared light can be used to obtain the target body temperature of a specified person at different sleep times. A sleep curve can include the target body temperature at different sleep times and the corresponding target temperature, which is the corresponding comfortable ambient temperature. By obtaining the target body temperature of a specified person at different sleep times, calculating the target temperature corresponding to the target body temperature, and obtaining the corresponding relationship between the target body temperature and the target temperature at different sleep times, a sleep curve is generated. This sleep curve can be generated for naps, nighttime sleep, and any other sleep time, allowing for tailored sleep adjustments to the user's sleep pattern at different sleep times. This provides a highly targeted approach and helps improve sleep comfort.

[0098] In one embodiment of the present invention, operating the air conditioner according to the target sleep curve may include:

[0099] At preset time intervals, the real-time ambient temperature of the environment where the air conditioner is located is obtained, and the real-time ambient temperature is compared with the target temperature at the same time as the real-time ambient temperature in the target sleep curve to determine whether the real-time ambient temperature is the same;

[0100] If they are different, adjust the operating parameters of the air conditioner so that the real-time ambient temperature and the target temperature in the target sleep curve are the same.

[0101] In this embodiment, the preset time interval t is modifiable. The preset time interval t can generally be any value between 1 and 5 minutes, such as 2 minutes or 4 minutes. The real-time ambient temperature of the environment where the air conditioner is located is obtained, and the real-time ambient temperature is compared with the target temperature in the target sleep curve at the same time as the real-time ambient temperature. If they are different, the operating parameters of the air conditioner are adjusted to ensure that the real-time ambient temperature and the target temperature in the target sleep curve are the same, thereby ensuring the sleep comfort of the individual.
