Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air conditioner control method and an air conditioner. Background Technology

[0002] With the development of science and technology and the continuous improvement of people's living standards, air conditioners have become an indispensable household appliance. As technology in the home appliance industry matures and competition intensifies, consumers are demanding higher and higher quality air conditioners.

[0003] However, in related technologies, air conditioners cannot adjust their operating parameters according to the user's physical condition, thus failing to meet the user's comfort requirements. Summary of the Invention

[0004] To address the problem that air conditioners cannot adjust their operating parameters according to the user's physical condition, thus failing to meet the user's comfort requirements, this invention provides an air conditioner control method. The control method includes: acquiring the user's heart rate using a smart wearable device; determining whether the heart rate is greater than a heart rate threshold; if the heart rate is greater than the heart rate threshold, acquiring the user's body surface temperature and perspiration volume using the smart wearable device, and controlling the indoor fan speed and the air outlet angle of the air guide plate based on the body surface temperature and perspiration volume.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: By acquiring the user's heart rate through a smart wearable device, it is possible to determine whether the user's heart rate is high based on the relationship between the user's heart rate and the heart rate threshold. If the heart rate is higher than the heart rate threshold, it indicates that the user's current heart rate is high and the user is in an exercise state. Therefore, by acquiring the user's body surface temperature and perspiration amount through the smart wearable device, the indoor fan speed and the air outlet angle of the air guide plate are controlled based on the user's body surface temperature and perspiration amount to increase the air volume and air outlet direction of the indoor unit, thereby improving the cooling comfort of the user during exercise.

[0006] In one embodiment of the present invention, the step of controlling the indoor fan speed and the air guide angle based on the body surface temperature and the amount of sweat includes: if the body surface temperature is greater than a first body surface temperature threshold and the amount of sweat is greater than or equal to the amount of sweat threshold, then the indoor fan speed is adjusted to the maximum speed and the air guide is adjusted to the anti-direct blowing angle.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: If the body surface temperature is greater than the first body surface temperature threshold and the amount of sweat is greater than or equal to the sweat amount threshold, it indicates that the user's body surface temperature is relatively high and the user's amount of sweat is relatively large. Considering that the user's amount of sweat is relatively large, if a large amount of cold air blows directly on the user, the user will get cold due to the evaporation of a large amount of sweat on the skin surface. Therefore, the air guide plate is adjusted to the anti-direct-blow temperature. In order to improve the cooling effect and achieve rapid cooling, the indoor fan speed is adjusted to the maximum speed to increase the air volume and avoid the cooling effect being reduced due to the air guide plate being adjusted to the anti-direct-blow angle, which would affect the cooling comfort.

[0008] In one embodiment of the present invention, the step of controlling the indoor fan speed and the air outlet angle of the air guide plate according to the body surface temperature and the amount of sweating further includes: if the body surface temperature is greater than a first body surface temperature threshold and the amount of sweating is less than a sweating threshold, then the indoor fan speed is adjusted to the maximum speed, and the air outlet angle of the air guide plate is adjusted according to the body surface temperature.

[0009] Compared with existing technologies, the technical effects achieved by this solution are as follows: If the body surface temperature is greater than a first body surface temperature threshold and the amount of sweat is less than a sweat amount threshold, it indicates that the user's body surface temperature is relatively high but the amount of sweat is relatively low. Therefore, the indoor fan speed is adjusted to the maximum speed to increase the air volume and achieve rapid cooling. Since the user's amount of sweat is relatively low, even if the cold air blows directly on them, there will not be a large amount of sweat evaporation on the skin surface. Therefore, the air outlet angle of the air guide plate can be adjusted according to the user's body surface temperature to ensure user comfort while achieving rapid cooling.

[0010] In one embodiment of the present invention, controlling the air outlet angle of the air guide plate according to the body surface temperature includes: obtaining the temperature change rate of the body surface temperature within a first time period; and controlling the air outlet angle of the air guide plate according to the temperature change rate.

[0011] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by acquiring the rate of temperature change of body surface temperature within a first time period, the cooling effect of the air conditioner can be determined based on the rate of temperature change, thereby allowing the air outlet angle of the air guide plate to be adjusted according to the cooling effect of the air conditioner to ensure the user's cooling comfort.

[0012] In one embodiment of the present invention, controlling the air outlet angle of the air guide plate according to the temperature change rate includes: if the temperature change rate is less than a temperature change rate threshold, then A = A0 + a * ΔT / t1; if the temperature change rate is greater than the temperature change rate threshold, then A = A0 - a * ΔT / t1; if the temperature change rate is equal to the temperature change rate threshold, then A = A0; where A is the air outlet angle of the air guide plate; A0 is the current air outlet angle of the air guide plate; a is a coefficient; ΔT is the change value of body surface temperature; and t1 is the first duration.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: If the rate of temperature change is less than the temperature change rate threshold, it indicates that the user's body temperature is decreasing slowly, and the air conditioner's cooling effect is not very good. Therefore, the air outlet angle of the air guide vane is increased to increase the air volume and improve the cooling effect. If the rate of temperature change is greater than the temperature change rate threshold, it indicates that the user's body temperature is decreasing quickly, and the air conditioner's cooling effect is good. Therefore, the air outlet angle of the air guide vane is decreased to reduce the air volume and prevent the user from getting cold. If the rate of temperature change is equal to the temperature change rate threshold, it indicates that the current air outlet angle is suitable and no adjustment is needed. Therefore, the air conditioner can continue to operate at the current air outlet angle of the air guide vane.

[0014] In one embodiment of the present invention, the control method of the air conditioner further includes: obtaining the duration for which the heart rate is greater than a heart rate threshold; if the duration is greater than a second duration, controlling the air conditioner to turn on the fresh air mode, and determining the speed of the fresh air fan according to the duration.

[0015] Compared to existing technologies, the technical effects achieved by this solution are as follows: If the duration of a heart rate exceeding the heart rate threshold is longer than the second duration, it indicates that the user's exercise intensity is relatively high and has been sustained for a period of time. This suggests a high indoor carbon dioxide concentration and a feeling of stuffiness. Therefore, the air conditioner's fresh air mode is activated to ventilate and reduce the indoor carbon dioxide concentration. Based on the duration of the heart rate exceeding the heart rate threshold, the indoor ventilation demand can be accurately determined, allowing for the adjustment of the fresh air fan speed to ensure cooling comfort for the user during exercise.

[0016] In one embodiment of the present invention, determining the fresh air fan speed based on the duration includes: n xf =n0 + n0*(t-t2) / t2; where, n xf n is the fresh air fan speed; n0 is the fresh air fan base speed; t is the duration; t2 is the second duration.

[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: the longer the heart rate is above the heart rate threshold, the higher the indoor carbon dioxide concentration, and the greater the indoor ventilation demand, thus requiring a larger fresh air fan speed.

[0018] In one embodiment of the present invention, the control method of the air conditioner further includes: if the heart rate is less than or equal to the heart rate threshold, determining whether the user is in a sleep state based on the smart wearable device; if the user is in a sleep state, determining whether the body surface temperature is less than a second body surface temperature threshold; if the body surface temperature is less than or equal to the second body surface temperature threshold, increasing the set temperature of the air conditioner.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: If the heart rate is lower than the heart rate threshold, it indicates that the user is not in a state of exercise; therefore, the smart wearable device determines whether the user is asleep. When the user is asleep, if the body surface temperature is lower than the second body surface temperature threshold, it indicates that the user's body surface temperature is relatively low. To prevent the user from catching a cold or being woken up by the cold after falling asleep, the air conditioner's set temperature is increased to ensure the user's sleep comfort.

[0020] This invention provides an air conditioner that implements any of the control methods described above. The air conditioner includes: an acquisition module for acquiring a user's heart rate using a smart wearable device; a judgment module for judging whether the heart rate is greater than a heart rate threshold; and a control module for, when the heart rate is greater than the heart rate threshold, acquiring the user's body surface temperature and perspiration amount using the smart wearable device, and controlling the indoor fan speed and the air outlet angle of the air guide plate based on the body surface temperature and perspiration amount.

[0021] This invention provides an air conditioner, which includes a computer-readable storage medium storing a computer program and a packaged IC. When the computer program is read and executed by the packaged IC, the air conditioner implements any of the control methods for air conditioners described above.

[0022] By adopting the technical solution of the present invention, the following technical effects can be achieved:

[0023] (1) By obtaining the user's heart rate from the smart wearable device, it is possible to determine whether the user's heart rate is relatively high based on the relationship between the user's heart rate and the heart rate threshold. If the heart rate is greater than the heart rate threshold, it indicates that the user's current heart rate is high and the user is in an exercise state. Therefore, by obtaining the user's body surface temperature and sweat volume from the smart wearable device, the indoor fan speed and the air outlet angle of the air guide plate are controlled based on the user's body surface temperature and sweat volume to increase the air volume and air outlet direction of the indoor unit, thereby improving the cooling comfort of the user in an exercise state.

[0024] (2) If the body surface temperature is greater than the first body surface temperature threshold and the amount of sweating is greater than or equal to the amount of sweating threshold, it means that the user's body surface temperature is relatively high and the user's amount of sweating is relatively large. Considering that the user's amount of sweating is relatively large, if a large amount of cold air blows directly, the user will get cold due to the evaporation of a large amount of sweat on the skin surface. Therefore, the air guide plate is adjusted to the anti-direct blowing temperature. In order to improve the cooling effect and achieve rapid cooling, the indoor fan speed is adjusted to the maximum speed to increase the air volume and avoid the cooling effect being worsened and the cooling comfort being affected by adjusting the air guide plate to the anti-direct blowing angle.

[0025] (3) If the duration of the heart rate being greater than the heart rate threshold is longer than the second duration, it indicates that the user's exercise intensity is relatively high and they have been exercising for a period of time. This suggests a high indoor carbon dioxide concentration and a stuffy feeling for the user. Therefore, the air conditioner's fresh air mode should be turned on to ventilate and reduce the indoor carbon dioxide concentration. Based on the duration of the heart rate being greater than the heart rate threshold, the indoor ventilation demand can be accurately determined, allowing the fresh air fan speed to be adjusted accordingly to ensure the user's cooling comfort during exercise.

[0026] Figure 1 This is a flowchart illustrating a control method for an air conditioner provided by the present invention.

[0027] Figure 2 This is a schematic diagram of an air conditioner module provided by the present invention. Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] See Figure 1 This is a flowchart illustrating a control method for an air conditioner provided by the present invention. The control method includes: acquiring a user's heart rate using a smart wearable device; determining whether the heart rate is greater than a heart rate threshold; if the heart rate is greater than the heart rate threshold, acquiring the user's body surface temperature and perspiration volume using the smart wearable device, and controlling the indoor fan speed and the air outlet angle of the air guide plate based on the body surface temperature and perspiration volume. For example, the smart wearable device is a fitness tracker; the heart rate threshold is 100 beats per second.

[0030] Understandably, by obtaining the user's heart rate from the smart wearable device, it is possible to determine whether the user's heart rate is relatively high based on the relationship between the user's heart rate and the heart rate threshold. If the heart rate is greater than the heart rate threshold, it indicates that the user's current heart rate is high and the user is in a state of exercise. Therefore, by obtaining the user's body surface temperature and amount of sweat from the smart wearable device, the indoor fan speed and the air outlet angle of the air guide plate are controlled according to the user's body surface temperature and amount of sweat, so as to increase the air volume and air outlet direction of the indoor unit, thereby improving the cooling comfort of the user in a state of exercise.

[0031] Furthermore, controlling the indoor fan speed and the air guide angle based on the body surface temperature and the amount of sweat includes: if the body surface temperature is greater than a first body surface temperature threshold and the amount of sweat is greater than or equal to a sweat amount threshold, then the indoor fan speed is adjusted to the maximum speed, and the air guide is adjusted to an angle to prevent direct airflow. For example, the preferred value of the first body surface temperature threshold is 37°C; the sweat amount threshold can be specifically set according to the user's weight, age, and gender.

[0032] Understandably, if the body surface temperature is greater than the first body surface temperature threshold and the amount of sweat is greater than or equal to the sweat amount threshold, it indicates that the user's body surface temperature is relatively high and the user's sweating is relatively large. Considering that the user's sweating is relatively large, if a large amount of cold air blows directly on the user, the user will catch a cold due to the evaporation of a large amount of sweat on the skin surface. Therefore, the air guide is adjusted to the anti-direct-blow temperature. In order to improve the cooling effect and achieve rapid cooling, the indoor fan speed is adjusted to the maximum speed to increase the air volume and avoid the cooling effect being reduced due to the air guide being adjusted to the anti-direct-blow angle, which would affect the cooling comfort.

[0033] Furthermore, the step of controlling the indoor fan speed and the air outlet angle of the air guide plate according to the body surface temperature and the amount of sweating also includes: if the body surface temperature is greater than a first body surface temperature threshold and the amount of sweating is less than a sweating threshold, then the indoor fan speed is adjusted to the maximum speed, and the air outlet angle of the air guide plate is adjusted according to the body surface temperature.

[0034] Understandably, if the body surface temperature is higher than the first body surface temperature threshold and the amount of sweat is lower than the sweat amount threshold, it indicates that the user's body surface temperature is relatively high but the amount of sweat is relatively low. Therefore, the indoor fan speed is adjusted to the maximum speed to increase the air volume and achieve rapid cooling. Since the user's amount of sweat is relatively low, even if the cold air blows directly on them, there will not be a large amount of sweat evaporation on the skin surface. Therefore, the air outlet angle of the air guide can be adjusted according to the user's body surface temperature to ensure the user's cooling comfort while achieving rapid cooling.

[0035] Furthermore, controlling the air outlet angle of the air guide plate based on the body surface temperature includes: acquiring the temperature change rate of the body surface temperature within a first time period; and controlling the air outlet angle of the air guide plate based on the temperature change rate.

[0036] It is understandable that by obtaining the rate of temperature change of body surface temperature within a first time period, the cooling effect of the air conditioner can be determined based on this rate of temperature change. Therefore, the air outlet angle of the air guide plate can be adjusted according to the cooling effect of the air conditioner to ensure the user's cooling comfort.

[0037] Furthermore, controlling the air outlet angle of the air guide plate according to the temperature change rate includes: if the temperature change rate is less than a temperature change rate threshold, then A = A0 + a * ΔT / t1; if the temperature change rate is greater than the temperature change rate threshold, then A = A0 - a * ΔT / t1; if the temperature change rate is equal to the temperature change rate threshold, then A = A0; where A is the air outlet angle of the air guide plate; A0 is the current air outlet angle of the air guide plate; a is a coefficient; ΔT is the change in body surface temperature; and t1 is a first duration. For example, the preferred value of the first duration is 5 minutes; the temperature change rate threshold is 0.5℃ / minute.

[0038] Understandably, if the rate of temperature change is less than the threshold, it means the user's body temperature is decreasing slowly, and the air conditioner's cooling effect is not very good. Therefore, the air outlet angle of the air deflector should be increased to increase the air volume and improve the cooling effect. If the rate of temperature change is greater than the threshold, it means the user's body temperature is decreasing quickly, and the air conditioner's cooling effect is good. Therefore, the air outlet angle of the air deflector should be decreased to reduce the air volume and prevent the user from getting cold. If the rate of temperature change equals the threshold, it means the current air outlet angle is appropriate and no adjustment is needed. Therefore, the air conditioner can continue to operate at the current air outlet angle.

[0039] Furthermore, the control method for the air conditioner also includes: obtaining the duration for which the heart rate is greater than a heart rate threshold; if the duration is greater than a second duration, controlling the air conditioner to turn on the fresh air mode, and determining the fresh air fan speed based on the duration. For example, a preferred value for the second duration is 30 minutes.

[0040] Understandably, if the duration of a heart rate exceeding the heart rate threshold is longer than the second duration, it indicates that the user's exercise intensity is relatively high and has been sustained for a period of time. This suggests a high indoor carbon dioxide concentration, causing the user to feel stuffy. Therefore, the air conditioner's fresh air mode is activated to ventilate and reduce the indoor carbon dioxide concentration. Based on the duration of the heart rate exceeding the heart rate threshold, the indoor ventilation demand can be accurately determined, allowing the fresh air fan speed to be adjusted accordingly to ensure the user's cooling comfort during exercise.

[0041] Furthermore, determining the fresh air fan speed based on the duration includes: n xf =n0 + n0*(t-t2) / t2; where, n xf n is the fresh air fan speed; n0 is the fresh air fan base speed; t is the duration; t2 is the second duration.

[0042] Understandably, the longer the heart rate remains above the heart rate threshold, the higher the indoor carbon dioxide concentration and the greater the demand for indoor ventilation, thus requiring a higher fresh air fan speed.

[0043] Furthermore, the control method for the air conditioner also includes: if the heart rate is less than or equal to the heart rate threshold, determining whether the user is in a sleep state based on the smart wearable device; if the user is in a sleep state, determining whether the body surface temperature is less than a second body surface temperature threshold; if the body surface temperature is less than or equal to the second body surface temperature threshold, increasing the set temperature of the air conditioner. For example, a preferred value for the second body surface temperature threshold is 35°C.

[0044] Understandably, if the heart rate is below the heart rate threshold, it indicates that the user is not in a state of exercise. Therefore, the smart wearable device determines whether the user is asleep. When the user is asleep, if the body surface temperature is below the second body surface temperature threshold, it indicates that the user's body surface temperature is relatively low. To prevent the user from catching a cold or being woken up by the cold after falling asleep, the air conditioner's set temperature is increased to ensure the user's sleep comfort.

[0045] Furthermore, this invention provides an air conditioner. (In conjunction with...) Figure 2 The air conditioner 200 includes, for example, an acquisition module 210, a judgment module 220, and a control module 230. The acquisition module 210 acquires the user's heart rate using a smart wearable device; the judgment module 220 determines whether the heart rate is greater than a heart rate threshold; and the control module 230, if the heart rate is greater than the heart rate threshold, acquires the user's body surface temperature and perspiration volume using the smart wearable device, and controls the indoor fan speed and the air outlet angle of the air guide plate based on the body surface temperature and perspiration volume.

[0046] In one specific embodiment, the acquisition module 210, the judgment module 220, and the control module 230 cooperate with each other to implement any of the control methods for an air conditioner as described above, and can achieve the same technical effect. To avoid repetition, they will not be described again here.

[0047] Furthermore, this invention provides an air conditioner comprising: a computer-readable storage medium storing a computer program and a packaged IC. When the computer program is read and executed by the packaged IC, the air conditioner implements any of the control methods for air conditioners described above and achieves the same effect. To avoid repetition, further details are omitted here.

[0048] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
