Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
It should be noted that the terms "first", "second" and "third" in the description of the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Based on the problem that the air supply temperature of the existing air conditioner cannot be automatically adjusted, which is pointed out by the background art, the invention provides a control method for the air conditioner and the air conditioner, aiming at enabling the air conditioner to automatically adjust the air supply temperature, enabling a user to be always in the most appropriate temperature environment, improving the comfort level of the user, avoiding the body discomfort or illness of the user and improving the user experience.
Specifically, as shown in fig. 1, the control method of the present invention includes: acquiring the surface temperature of a human body and the indoor environment temperature; the air supply temperature of the air conditioner is selectively adjusted according to the surface temperature of the human body and the indoor environment temperature. Wherein, can gather the temperature of human surface through the infrared sensor who sets up on the air conditioner, also perhaps dress on the human body and gather human surface temperature with the controller communication connection's of air conditioner temperature sensor, the collection mode that technical staff in the art can set up human surface temperature in a flexible way in practical application, as long as can acquire human surface temperature. Correspondingly, indoor environment temperature can acquire through indoor environment temperature sensor, and this indoor environment temperature sensor and the controller communication connection of air conditioner, so that can in time transmit the indoor environment temperature who gathers for the controller of air conditioner, and indoor environment temperature sensor's specific mounted position does not establish the restriction, both can install on the air conditioner, also can install on indoor wall or other consumer, as long as indoor environment temperature sensor can with the indoor environment temperature gather after transmit for the controller of air conditioner can. In addition, because the human face is generally in an exposed state, and the human face temperature can reflect the overall comfort condition of the human, the human surface temperature is preferably the human face temperature, and certainly, the human surface temperature can also be the temperature of other exposed positions of the human body, such as hands, neck and/or arms, and the like.
Preferably, the step of selectively adjusting the air supply temperature of the air conditioner according to the surface temperature of the human body and the indoor environment temperature specifically comprises: comparing the difference value between the surface temperature of the human body and the indoor environment temperature with a first preset temperature value; if the difference value between the surface temperature of the human body and the indoor environment temperature is larger than or equal to a first preset temperature value, reducing the air supply temperature of the air conditioner; and if the difference value between the surface temperature of the human body and the indoor environment temperature is less than the first preset temperature value, the air supply temperature of the air conditioner is not adjusted. The control mode is more suitable for hot summer, when the surface temperature of a human body is higher than the indoor environment temperature, the user is judged to be hotter at the moment, the air conditioner is required to reduce the air supply temperature, and if the surface temperature of the human body is lower than the indoor environment temperature, the air conditioner is not required to adjust the air supply temperature. In this embodiment, the first preset temperature value may be 8 ℃, 9 ℃, or 10 ℃, and the like, and a person skilled in the art may flexibly set the specific temperature of the first preset temperature value in practical application, as long as it can be determined whether the air conditioner needs to adjust the air supply temperature through the temperature demarcation point determined by the first preset temperature value.
Preferably, the control method of the present invention may also be applied to a cold winter season, for example, the step of "selectively adjusting the supply air temperature of the air conditioner according to the human body surface temperature and the indoor ambient temperature" specifically includes: comparing the human body surface temperature with the indoor environment temperature; if the surface temperature of the human body is lower than the indoor environment temperature, the air conditioner needs to raise the air supply temperature; if the surface temperature of the human body is not lower than the indoor ambient temperature, the air conditioner does not need to adjust the air supply temperature. That is, when the surface temperature of the human body is too low, the air conditioner needs to raise the air supply temperature to warm the human body, and when the surface temperature of the human body is not low, the air conditioner does not need to adjust the air supply temperature. Of course, the above-mentioned manner of directly comparing the human body surface temperature with the indoor environment temperature is only exemplary, in practical applications, the difference between the human body surface temperature and the indoor environment temperature may also be compared with a set value, or the ratio of the human body surface temperature to the indoor environment temperature may also be compared with a set value, and those skilled in the art may flexibly set the manner of comparing the human body surface temperature with the indoor environment temperature in practical applications. In addition, the control method of the present invention can be applied to other seasons or environments besides the hot summer and the cold winter, and different control strategies can be set, and it should be noted that the technical scheme of determining whether to adjust the air supply temperature or not by using two parameters, namely the human body surface temperature and the indoor environment temperature, should be limited within the protection scope of the present invention.
Further preferably, the step of selectively adjusting the air supply temperature of the air conditioner according to the surface temperature of the human body and the indoor environment temperature specifically comprises: acquiring the outdoor environment temperature; the air supply temperature of the air conditioner is selectively adjusted according to the surface temperature of the human body, the indoor environment temperature and the outdoor environment temperature. Specifically, the step of selectively adjusting the air supply temperature of the air conditioner according to the human body surface temperature, the indoor environment temperature and the outdoor environment temperature includes: comparing the difference between the surface temperature of the human body and the indoor environment temperature with a first preset temperature value, and comparing the difference between the outdoor environment temperature and the indoor environment temperature with a second preset temperature value; if the difference value between the surface temperature of the human body and the indoor environment temperature is greater than or equal to a first preset temperature value, and the difference value between the outdoor environment temperature and the indoor environment temperature is greater than or equal to a second preset temperature value, reducing the air supply temperature of the air conditioner; if the difference value between the surface temperature of the human body and the indoor environment temperature is smaller than a first preset temperature value, or the difference value between the outdoor environment temperature and the indoor environment temperature is smaller than a second preset temperature value, the air supply temperature of the air conditioner is not adjusted. This kind of control mode also is more applicable to hot summer, under this kind of condition, need human surface temperature to compare in indoor ambient temperature and outdoor ambient temperature compare in indoor ambient temperature homogeneous phase difference when great, the air conditioner just can think that the people needs cooler temperature environment, the air conditioner needs to reduce air supply temperature this time, and when human surface temperature compares in indoor ambient temperature not big or outdoor ambient temperature compares in indoor ambient temperature not big, the air conditioner can think that the people has been in more suitable temperature environment this moment, consequently can not adjust air supply temperature. Similarly to the above, the control method of this embodiment may also be applied to different seasons or environments, only corresponding control logics need to be formulated, and the specific comparison method between the human body surface temperature, the indoor environment temperature, and the outdoor environment temperature may also be flexibly set. In this embodiment, the first preset temperature value may be 8 ℃, 9 ℃ or 10 ℃, and the second preset temperature value may be 10 ℃, 12 ℃ or 15 ℃, and the like, and those skilled in the art may flexibly set the specific temperatures of the first preset temperature value and the second preset temperature value in practical application, as long as it is possible to determine whether the air conditioner needs to adjust the air supply temperature through the temperature boundary point determined by the first preset temperature value and the second preset temperature value.
Preferably, during the air supply process of the air conditioner, the control method of the invention further comprises the following steps: identifying human facial features; obtaining an age of the person based on the facial features of the person; if the age of the person is larger than or equal to a first preset value, the air conditioner enters an air supply automatic avoiding mode; if the age of the person is smaller than the first preset value and larger than the second preset value, the air conditioner enters an air supply automatic following mode; and if the age of the person is less than or equal to the second preset value, the air conditioner enters an air supply automatic avoiding mode. The human face image can be acquired by adopting an image acquisition device (such as a camera, a video camera and the like) for identifying the human face characteristics, then the data of the human face image is transmitted to a controller of the air conditioner for analysis and processing, so that the age of a person is obtained according to the human face characteristics (such as face color, hair color and/or wrinkle length and the like), and then the air conditioner enters an air supply automatic avoiding mode/an air supply automatic following mode according to the age of the person. The first preset value and the second preset value can divide the age of the person in three sections, the first section (namely the age of the person is larger than or equal to the first preset value) is an old person, the second section (namely the age of the person is smaller than the first preset value and larger than the second preset value) is a young year or a middle year, and the third section (namely the age of the person is smaller than or equal to the second preset value) is a child. Because the physique of old people and children is slightly weak, the air conditioner is suitable for adopting an air supply automatic avoiding mode, namely the air conditioner can not blow directly towards places with the old people and the children, and the physique of young and middle-aged people is stronger, namely the air conditioner can intensively supply air towards the places with the young and middle-aged people. The realization of the automatic air supply avoiding mode and the automatic air supply following mode of the air conditioner can be realized by depending on the vertical air deflector and the horizontal air deflector in the prior art, and the description is omitted here. In addition, the first preset value may be 65 years old, the second preset value may be 15 years old, that is, the age of a person is greater than or equal to 65 years old, less than or equal to 15 years old is considered as a child, and less than 65 years old and greater than 15 years old is considered as a young or middle-aged person, of course, the first preset value and the second preset value are only exemplary, and a person skilled in the art may flexibly set specific age values of the first preset value and the second preset value in practical application, as long as an age demarcation point determined by the first preset value and the second preset value enables the air conditioner to determine whether to enter the air supply automatic avoiding mode or the air supply automatic following mode.
Preferably, before the air conditioner supplies air, the control method further comprises: acquiring the surface temperature of a human body and the temperature of an air outlet of an air conditioner; if the difference value between the surface temperature of the human body and the air outlet temperature of the air conditioner is greater than or equal to a third preset temperature value, the air conditioner supplies air; if the difference value between the surface temperature of the human body and the air outlet temperature of the air conditioner is smaller than a third preset temperature value, the air conditioner does not supply air. After the air conditioner begins to operate or before the operation promptly, gather human surface temperature and the air outlet temperature of air conditioner earlier (can set up temperature sensor and carry out temperature acquisition in the air outlet department of air conditioner), if human surface temperature compares when the air outlet temperature of air conditioner is great, the air conditioner is affirmed the people and is required the air conditioner and supply air this moment, and if human surface temperature compares when the air outlet temperature of air conditioner is not big, the air conditioner is affirmed the people and is not required the air conditioner and supply air this moment.
The solution according to the invention will be further elucidated with reference to a most preferred embodiment.
As shown in fig. 2, after the air conditioner is started, the temperature of the human face and the temperature of the air outlet of the air conditioner are automatically acquired; judging whether the starting condition of the air supply automatic mode of the air conditioner is met or not according to the human face temperature and the air outlet temperature of the air conditioner, namely, if the difference value between the human face temperature and the air outlet temperature of the air conditioner is greater than or equal to a third preset temperature value, starting the air supply automatic mode by the air conditioner to start air supply; if the difference value between the human body face temperature and the air outlet temperature of the air conditioner is smaller than a third preset temperature value, the air conditioner does not start an air supply automatic mode and continues to acquire the human body face temperature and the air outlet temperature of the air conditioner; after the automatic air supply mode is started, identifying human facial features; obtaining an age of the person based on the facial features of the person; if the age of the person is larger than or equal to a first preset value (namely the person is the old), the air conditioner enters an air supply automatic avoiding mode; if the age of the person is smaller than the first preset value and larger than the second preset value (namely, the person is young or middle-aged), the air conditioner enters an air supply automatic following mode; if the age of the person is less than or equal to a second preset value (namely, the person is a child), the air conditioner enters an air supply automatic avoiding mode. In the process that the air conditioner executes an air supply automatic following mode or an air supply automatic avoiding mode, the face temperature, the indoor environment temperature and the outdoor environment temperature of a human body are obtained, judging whether the condition of the air conditioner for automatically adjusting the air supply temperature is met or not according to the face temperature of the human body, the indoor environment temperature and the outdoor environment temperature, namely, the difference value between the human face temperature and the indoor environment temperature is more than or equal to a first preset temperature value, and the difference value between the outdoor environment temperature and the indoor environment temperature is more than or equal to a second preset temperature value, the air conditioner automatically adjusts the air supply temperature, if the difference between the human face temperature and the indoor environment temperature is less than a first preset temperature value or the difference between the outdoor environment temperature and the indoor environment temperature is less than a second preset temperature value, the air conditioner does not automatically adjust the supply air temperature and continues to acquire the human face temperature, the indoor ambient temperature, and the outdoor ambient temperature.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
