Step S301, under the condition that the electric auxiliary heating device operates, determining the current heat-resisting critical temperature according to the indoor user.
The operation of the electric auxiliary heating device means that the electric auxiliary heating device is in an open state, which can be a high-power open state, for example, two groups of electric auxiliary heating devices are in an operating state; or a low power on state, such as one set of electric auxiliary heating devices operating and another set of electric auxiliary heating devices off.
And the heat-resisting critical temperature is used for representing a critical temperature value which does not influence the comfort degree of a user when the user approaches the air outlet.
Further, when the auxiliary heating function instruction is triggered, the electric auxiliary heating device is controlled to operate.
The auxiliary heating function instruction can be triggered by the action of a user. For example, the user presses a secondary heating function button on the air conditioner remote controller, or turns on the secondary heating function of the air conditioner through an application program on the mobile phone. The auxiliary heating function instruction can also be triggered by the difference value between the current indoor environment temperature and the set temperature. For example, in the heating mode, if the difference between the indoor ambient temperature and the set temperature is greater than the auxiliary heating threshold, the auxiliary heating function command is triggered to control the operation of the electric auxiliary heating device, so as to improve the heating efficiency.
Step S302, when it is detected that the current distance between the user and the air outlet of the air conditioner is smaller than a first distance threshold value, a first air outlet temperature of the air outlet is obtained.
The first distance threshold is used for representing a distance value which is possibly influenced by the current air outlet temperature to the comfort level of the user when the user is close to an air outlet of the air conditioner. The distance between the user and the air outlet of the air conditioner can be obtained by the distance detection device in fig. 2. Such as infrared sensors, radar sensors, etc. The distance between the user and the air-conditioning outlet can also be acquired through wearable equipment of the user, such as a smart watch, a smart bracelet and the like.
Step S303, if the first outlet air temperature is greater than the heat-resistant critical temperature, the operation intensity of the electric auxiliary heating device is reduced, and a maintaining time length during which the current distance between the user and the air outlet is less than the first distance threshold is obtained.
When the first air outlet temperature is higher than the heat-resisting critical temperature, the air outlet temperature of the current air outlet can enable a user to have a high-temperature baking feeling, and the air outlet comfort level is affected. Therefore, the running strength of the electric auxiliary heating device is reduced, so that the air outlet temperature of the air outlet of the air conditioner is reduced, and the influence of high-temperature air outlet on users is reduced.
The maintaining time length that the current distance between the user and the air outlet is smaller than the first distance threshold value is used for showing that the user receives the current air outlet temperature after the air conditioner air outlet temperature is reduced along with the reduction of the operation intensity of the electric auxiliary heating device.
In step S304, if the duration is longer than the first set duration, a second outlet air temperature of the outlet is obtained.
The longer the duration of the maintenance, the smaller the influence of the current air outlet temperature on the comfort of the user. And acquiring the air outlet temperature of the air outlet as the second air outlet temperature.
Step S305, updating the current thermal-resistant critical temperature according to the second outlet air temperature.
Here, the second outlet air temperature is obtained when the duration of time for which the user is close to the air outlet is longer than the set duration after the operation intensity of the electric auxiliary heating device is reduced, that is, the temperature of the air outlet is reduced, that is, the user can receive the outlet air temperature. Therefore, the current heat-resisting critical temperature can be updated according to the air outlet temperature, so that the air outlet temperature of the air conditioner is more suitable for the current indoor environment condition and the indoor personnel demand.
Optionally, updating the current heatproof critical temperature according to the second outlet air temperature, including: and setting the current air outlet temperature as a new heat-resisting critical temperature.
Optionally, in other embodiments, a new thermal-resistant critical temperature may also be determined according to the parameter of the air conditioner during operation and the second outlet air temperature; the parameters during the operation of the air conditioner comprise environment parameters during the operation of the air conditioner and air outlet parameters during the operation of the air conditioner.
Here, the thermal critical temperature can be updated together with the current indoor condition and the second outlet air temperature. The environmental parameter may include an indoor ambient temperature and/or an indoor ambient humidity. Because the sensitivity of the user to hot air is different in different indoor environments, the second outlet air temperature can be adjusted by combining the environmental parameters of the air conditioner during operation, so that the heat-resisting critical temperature can be updated. And the air outlet parameters comprise air outlet speed and/or air outlet direction. The air outlet parameters have certain influence on the air supply heat felt by the user, the heat sensitivity of the user is higher when air is supplied at high air speed, and the heat sensitivity of the user is relatively reduced because the air supply impact is smaller when air is supplied at low air speed; when the air supply angle is the direct blowing, the air quantity can be directly sent to the user, and when the air supply angle is the upward air supply or the downward air supply, the air supply can not directly fall to the user, so the heat sensitivity of the user is higher during the direct blowing under the same air outlet temperature.
Optionally, determining a new thermal-resistant critical temperature according to the parameter when the air conditioner operates and the second outlet air temperature, including:
determining a first compensation value according to the air outlet speed of the air conditioner;
determining a second compensation value according to the current indoor environment temperature;
and determining a new heat-resisting critical temperature according to the second outlet air temperature, the first compensation value and the second compensation value.
Wherein the first compensation value is inversely related to the outlet air speed; the second compensation value is positively correlated with the current indoor ambient temperature.
Specifically, according to the second outlet air temperature and the first and second compensation values, determining a new thermal-resistant critical temperature, including:
determining the sum of the second outlet air temperature and the first compensation value and the second compensation value as a new heat-resisting critical temperature; or, determining the product of the second outlet air temperature and the first compensation value and the second compensation value as a new thermal-resistant critical temperature.
Therefore, in the operation process of the electric auxiliary heating device, the current heat-resisting critical temperature corresponding to the indoor user is obtained, and when the user approaches the air-conditioning outlet, whether the first air outlet temperature of the current air outlet is larger than the current heat-resisting critical temperature is determined. When the first air outlet temperature is higher than the current heat-resisting critical temperature, the air outlet temperature of the current air outlet indicates that a user has high-temperature baking feeling, the air outlet comfort degree is influenced, the air outlet temperature is reduced by reducing the operation intensity of the electric auxiliary heating device, the current heat-resisting critical temperature is updated according to the duration of the user close to the air outlet after the operation intensity of the electric auxiliary heating device is reduced, and the air outlet temperature of the air conditioner can be more suitable for the current indoor environment condition and the indoor personnel demand when the user is close to the air outlet.
Fig. 4 is a flowchart illustrating a method for controlling an air conditioner according to an embodiment of the present disclosure, which is applied to the air conditioner. In the embodiments of the present disclosure, a case will be described with a processor of an air conditioner as an execution subject.
Step S401, under the condition that the electric auxiliary heating device operates, acquiring the identity of the current indoor user and the heat-resisting critical temperature corresponding to the identity of the user.
In step S402, the thermal critical temperature with the lowest value is set as the current thermal critical temperature.
Here, the current heatproof critical temperature is determined by the relationship between the user identity and the heatproof critical temperature.
Here, the current indoor user may be determined by the current indoor user identity of the wearable device of the user and the positioning information of the wearable device of the user in the room.
The indoor environment image can also be obtained through the image acquisition device to obtain the user activity information. For example, an indoor environment image is obtained, and image features are extracted; when the image features represent the presence of an active user in the indoor environment, a user identity is further determined that is consistent with the image features. The image acquisition device may be an indoor monitoring device, or may be a household appliance with an image acquisition function, such as a television with a camera, an air conditioner, and the like.
The user identity can be obtained through user information associated with the wearable device, and can also be determined through image features extracted from the image obtaining device. The user identities may be classified according to age into young users (0-6 years), young users (7-18 years), adult users (18-60 years), and old users (over 60 years).
If the current indoor user identity is single, namely only 1 user exists indoors or a plurality of users with the same identity category, the heat-resisting critical temperature corresponding to the user identity is the lowest numerical value, and the heat-resisting critical temperature is determined as the current heat-resisting critical temperature.
And if the current indoor user identities are of multiple types, setting the heat-resisting critical temperature with the lowest numerical value as the current heat-resisting critical temperature.
The corresponding relation between the user identity and the heat-resisting critical temperature can be obtained in a test mode, the corresponding relation is stored in a database in a one-to-one corresponding data table mode, and after the current indoor user identity is obtained, the heat-resisting critical temperature corresponding to the current indoor user identity can be obtained by inquiring the database. And the corresponding relation between the user identity and the heat-resisting critical temperature can be obtained through the historical operating data of the air conditioner.
Specifically, the obtaining of the heat-resistant critical temperature corresponding to the user identity includes:
acquiring historical outlet air temperature of the air outlet of the air conditioner under the condition that the distance between a user and the air outlet is smaller than a second distance threshold value and the maintaining time length is longer than a second set time length when the electric auxiliary heating mode is operated before the current moment;
and determining the identity of the user, and setting the historical air outlet temperature as the heat-resisting critical temperature corresponding to the identity of the user.
Here, when the electric auxiliary heating mode is operated before the current time, it may refer to when the electric auxiliary heating mode is operated last time, or may refer to when the electric auxiliary heating mode is operated for the first time.
The distance between the user and the air outlet is smaller than a second distance threshold value, the duration is longer than a second set market, the influence of the air outlet temperature on the comfort level of the user is small, and the high-temperature baking feeling of the user is weak. At this moment, the historical air outlet temperature is recorded as the heat-resisting critical temperature of the user, so that the air outlet temperature of the air conditioner can be more suitable for the requirements of indoor personnel.
Step S403, when it is detected that the current distance between the user and the air outlet of the air conditioner is smaller than the first distance threshold, acquiring a first outlet air temperature of the air outlet.
Step S404, if the first outlet air temperature is higher than the heat-resisting critical temperature, the operation intensity of the electric auxiliary heating device is reduced, and the maintaining time length that the current distance between the user and the air outlet is smaller than the first distance threshold value is obtained.
In step S405, if the duration is longer than the first set duration, a second outlet air temperature of the outlet is obtained.
Step S406, updating the current thermal-resistant critical temperature according to the second outlet air temperature.
Therefore, in the operation process of the electric auxiliary heating device, the current heat-resisting critical temperature corresponding to the indoor user is obtained, and when the user approaches the air outlet of the air conditioner, whether the first air outlet temperature of the current air outlet is larger than the current heat-resisting critical temperature is determined. When the first air outlet temperature is higher than the current heat-resisting critical temperature, the air outlet temperature of the current air outlet indicates that a user has high-temperature baking feeling, the air outlet comfort degree is influenced, the air outlet temperature is reduced by reducing the operation intensity of the electric auxiliary heating device, the current heat-resisting critical temperature is updated according to the duration of the user close to the air outlet after the operation intensity of the electric auxiliary heating device is reduced, and the air outlet temperature of the air conditioner can be more suitable for the current indoor environment condition and the indoor personnel demand when the user is close to the air outlet.
Fig. 5 is a flowchart illustrating a method for controlling an air conditioner according to an embodiment of the present disclosure, which is applied to the air conditioner. In the embodiments of the present disclosure, a case will be described with a processor of an air conditioner as an execution subject.
Step S501, under the condition that the electric auxiliary heating device is operated, determining the current heat-resisting critical temperature according to the indoor user.
Step S502, when it is detected that the current distance between the user and the air outlet of the air conditioner is smaller than a first distance threshold value, a first air outlet temperature of the air outlet is obtained.
Step S503, if the first outlet air temperature is greater than the heat-resisting critical temperature, determining the operation intensity of the reduced electric auxiliary heating device according to the current difference value between the set temperature and the current indoor environment temperature.
Generally, when the electric auxiliary heating device operates in the mode, the indoor environment temperature is low, and the sensitivity of a user to high-temperature air supply is relatively high. Namely, the reduction of the outlet air temperature can be sensitively sensed. Therefore, the operation intensity of the reduced electric auxiliary heating device can be determined by setting the difference between the temperature and the indoor environment temperature, so that the reduced air outlet comfort degree is more suitable for the current indoor environment condition, and the influence of the operation intensity of the reduced electric auxiliary heating device on the current heating efficiency is reduced.
Optionally, the greater the difference between the set temperature and the indoor ambient temperature, the higher the operation intensity of the reduced electric auxiliary heating device.
The operating intensity can be expressed here by the power of the electric auxiliary heating device, the higher the operating power of the electric auxiliary heating device, the stronger the corresponding operating intensity. For example, the operating power of the electric auxiliary heating device is reduced by increasing the resistance value of the electric auxiliary heating device, thereby reducing the operating strength thereof. For another example, by reducing the number of operation groups of the electric auxiliary heating apparatuses, the operation power of the electric auxiliary heating apparatuses is reduced, thereby reducing the operation intensity thereof.
In addition, the operation intensity of the electric auxiliary heating device can be adjusted by adjusting the air speed of the air outlet. The higher the wind speed of the air outlet is, the more the heating quantity of the electric auxiliary heating device is sent out, and the stronger the operation intensity is. The operation intensity of the electric auxiliary heating device can be reduced by reducing the air outlet speed.
Specifically, determining the operation intensity of the reduced electric auxiliary heating device according to the current difference between the set temperature and the current indoor environment temperature includes:
when the current difference is smaller than the first difference, the operation intensity of the electric auxiliary heating device is reduced to be a first intensity;
when the current difference is larger than the first difference and smaller than the second difference, the operation intensity of the electric auxiliary heating device is reduced to be a second intensity;
the operation power of the electric auxiliary heating device corresponding to the first intensity is lower than that of the electric auxiliary heating device corresponding to the second intensity; and/or the air conditioner air outlet speed corresponding to the first strength is lower than the air conditioner air outlet speed corresponding to the second strength.
Alternatively, the first difference may be 3-5 deg.C, e.g., 3 deg.C, 4 deg.C, 5 deg.C; the second difference is set to 8-12 deg.C, such as 8 deg.C, 9 deg.C, 10 deg.C, 11 deg.C, 12 deg.C.
Step S504, obtaining the maintaining time length when the current distance between the user and the air outlet is smaller than the first distance threshold value.
In step S505, if the duration is longer than the first set duration, a second outlet air temperature of the outlet is obtained.
Step S506, the current thermal-resistant critical temperature is updated according to the second outlet air temperature.
Therefore, in the operation process of the electric auxiliary heating device, the current heat-resisting critical temperature corresponding to the indoor user is obtained, and when the user approaches the air outlet of the air conditioner, whether the first air outlet temperature of the current air outlet is larger than the current heat-resisting critical temperature is determined. When the first air outlet temperature is higher than the current heat-resisting critical temperature, the air outlet temperature of the current air outlet indicates that a user has high-temperature baking feeling, the air outlet comfort degree is influenced, the air outlet temperature is reduced by reducing the operation intensity of the electric auxiliary heating device, the current heat-resisting critical temperature is updated according to the duration of the user close to the air outlet after the operation intensity of the electric auxiliary heating device is reduced, and the air outlet temperature of the air conditioner can be more suitable for the current indoor environment condition and the indoor personnel demand when the user is close to the air outlet.
