Description

Control method for air conditioner and air conditioner

technical field

The invention belongs to the technical field of air conditioners, and specifically provides a control method for an air conditioner and an air conditioner.

Background technique

An air conditioner is a device that can cool/heat a room. For example, in a hot summer, an air conditioner can reduce the indoor temperature by cooling and supplying air, so as to make people feel comfortable.

In the existing air conditioner, after the user sets the target temperature, the air conditioner will automatically run, so that the indoor ambient temperature gradually increases/decreases to the target temperature and remains at the target temperature, and in the process of cooling/heating of the air conditioner. The user can change the target temperature at will. The change of the target temperature requires the user to actively issue a control command to the air conditioner. When a control command is issued to the air conditioner, the air conditioner will always supply air according to the current air supply temperature. This air supply method is easy to cause discomfort to the human body. For example, children with weak constitutions or the elderly are always under the same air supply temperature. It is very easy to get sick, which is not conducive to the user's experience.

Therefore, there is a need in the art for a new control method for an air conditioner and an air conditioner to solve the above problems.

In the preferred technical solution of the above-mentioned control method, the step of "selectively adjusting the air supply temperature of the air conditioner according to the human body surface temperature, the indoor ambient temperature and the outdoor ambient temperature" also includes: if the difference between the human body surface temperature and the indoor ambient temperature is If the value is smaller than the first preset temperature value, or the difference between the outdoor ambient temperature and the indoor ambient temperature is smaller than the second preset temperature value, the air supply temperature of the air conditioner is not adjusted.

In a preferred technical solution of the above control method, during the air supply process of the air conditioner, the control method further includes: identifying the facial features of the human body; obtaining the age of the person based on the facial features of the human body; if the age of the person is greater than or equal to the first preset value , the air conditioner enters the air supply automatic avoidance mode; if the age of the person is less than the first preset value and greater than the second preset value, the air conditioner enters the air supply automatic follow mode; if the age of the person is less than or equal to the second preset value value, the air conditioner enters the air supply automatic avoidance mode.

In a preferred technical solution of the above control method, before the air conditioner supplies air, the control method further includes: acquiring the body surface temperature and the air outlet temperature of the air conditioner; if the difference between the body surface temperature and the air outlet temperature of the air conditioner is greater than or When it is equal to the third preset temperature value, the air conditioner will supply air.

In a preferred technical solution of the above control method, the control method further includes: if the difference between the human body surface temperature and the air outlet temperature of the air conditioner is less than the third preset temperature value, the air conditioner does not supply air.

In another aspect, the present invention also provides an air conditioner including a controller configured to be able to execute the above-mentioned control method.

Those skilled in the art can understand that, in the preferred technical solution of the present invention, the air temperature of the air conditioner can be selectively adjusted by acquiring the surface temperature of the human body and the indoor ambient temperature. The surface temperature and the indoor ambient temperature are adjusted in real time, that is, the air conditioner can automatically adjust the supply air temperature, so that the user can always stay in the most suitable temperature environment, avoiding the user's physical discomfort or illness, and improving the user experience.

Further, the difference between the human body surface temperature and the indoor ambient temperature is compared with the first preset temperature value. If the above difference is greater than or equal to the first preset temperature value, it means that the human body surface temperature is high, and it is determined that the user is the user. If you feel hot, you need to improve the cooling of the air conditioner, that is, by reducing the air supply temperature of the air conditioner to continue to reduce the indoor ambient temperature, so that the surface temperature of the human body can be appropriately reduced, thereby improving user comfort and improving user experience; if If the above difference is smaller than the first preset temperature value, it means that the user is already in a relatively comfortable temperature environment at this time. At this time, there is no need to adjust the air supply temperature of the air conditioner to allow the user to stay in the most suitable ambient temperature, thereby improving the User comfort and improved user experience.

Further, on the basis of comparing the difference between the above-mentioned human body surface temperature and the indoor ambient temperature with the first preset temperature value, a judgment is made by adding the difference between the outdoor ambient temperature and the indoor ambient temperature and the second preset temperature value. Conditions can improve the necessity of the air conditioner to determine whether to adjust the supply air temperature, that is, when the indoor and outdoor ambient temperatures are greatly different, it means that the user needs the air conditioner to perform forced cooling and air supply at this time, and the air conditioner can determine that it is necessary to supply air. The air temperature is adjusted, and when the indoor and outdoor ambient temperatures are not much different, it means that the user does not particularly need the air conditioner for forced cooling and air supply at this time, but may only need the air conditioner for weak cooling and air supply. At this time, the air conditioner can determine that it is unnecessary to Supply air temperature regulation. In addition, by adding a judgment condition for comparing the difference between the outdoor ambient temperature and the indoor ambient temperature with the second preset temperature value, the accuracy of the air conditioner in judging whether to adjust the supply air temperature can also be improved, that is, the air conditioner can be prevented from misjudging. When the air conditioner obtains the body surface temperature deviation (for example, when the infrared sensor used to obtain the body surface temperature fails), supplementary judgment can be made based on the outdoor ambient temperature and the indoor ambient temperature, so that the air conditioner will not be deviated due to the obtained body surface temperature. The air temperature adjustment is frequently performed to avoid excessive energy consumption of the air conditioner due to misjudgment, and at the same time, the service life of the air conditioner is improved.

Still further, on the basis that the air conditioner automatically adjusts the air supply temperature, during the air supply process of the air conditioner, the age of the person is obtained by identifying the facial features of the human body. If the age of the person is greater than or equal to the first preset value, it is determined that The person is an elderly person. If the age of the person is less than or equal to the second preset value, the person is considered to be a child. Because the elderly and children are weak, the air conditioner should use the air supply automatic avoidance mode to avoid the air conditioner blowing directly on the human body. Avoid making the elderly or children feel uncomfortable or even sick. If the age of the person is less than the first preset value and greater than the second preset value, the person is considered to be young or middle-aged. It is advisable to adopt the air supply automatic follow mode, so that the air conditioner can always follow the human body to supply air, so that the human body feels comfortable. In this way, the air conditioner can automatically select the air supply mode according to the age of the person, and can automatically adjust the air supply temperature, so that the comfort of the human body is greatly improved, and the air conditioner can meet the needs of everyone, further improving the user experience.

Further, before the air conditioner supplies air, it is first judged whether the air conditioner starts to supply air by comparing the surface temperature of the human body and the air outlet temperature of the air conditioner. If the difference between the surface temperature of the human body and the air outlet temperature of the air conditioner is greater than or equal to the third preset temperature value, the air conditioner starts to supply air. If the above difference is less than the third preset temperature value, the air conditioner does not supply air. Through this control method, the air conditioner can automatically Turning on the air supply mode does not require the user to actively send the air supply control to the air conditioner, making the air conditioner more intelligent, and the air conditioner can start supplying air only when the user needs it, avoiding excess energy consumption and further improving the user. experience.

In addition, the air conditioner further provided by the present invention on the basis of the above-mentioned technical solution adopts the above-mentioned control method, and further has the technical effect possessed by the above-mentioned control method, and compared with the air conditioner before the improvement, the air conditioner of the present invention has The device can automatically adjust the supply air temperature, so that the user can always be in the most suitable temperature environment, improve the user's comfort, avoid the user's physical discomfort or illness, and improve the user experience.

Detailed ways

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 used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.

It should be noted that, in the description of the present invention, the terms "first", "second" and "third" are only used for description purposes, and cannot be understood as indicating or implying relative importance.

Based on the problem that the existing air conditioner cannot automatically adjust the supply air temperature pointed out in the background art, the present invention provides a control method for the air conditioner and the air conditioner, aiming at enabling the air conditioner to automatically adjust the supply air temperature, so that users can It can always be in the most suitable temperature environment, improve the user's comfort, avoid the user's physical discomfort or illness, and improve the user experience.

Specifically, as shown in FIG. 1 , the control method of the present invention includes: acquiring the human body surface temperature and the indoor ambient temperature; and selectively adjusting the air supply temperature of the air conditioner according to the human body surface temperature and the indoor ambient temperature. Among them, the temperature of the surface of the human body can be collected by an infrared sensor arranged on the air conditioner, or the temperature of the surface of the human body can be collected by wearing a temperature sensor connected to the controller of the air conditioner on the human body. In practical applications, the collection method of the surface temperature of the human body can be flexibly set, as long as the surface temperature of the human body can be obtained. Correspondingly, the indoor ambient temperature can be acquired through an indoor ambient temperature sensor, and the indoor ambient temperature sensor is connected in communication with the controller of the air conditioner, so that the collected indoor ambient temperature can be transmitted to the controller of the air conditioner in time, and The specific installation position of the indoor ambient temperature sensor is not limited. It can be installed on the air conditioner, indoor wall or other electrical equipment, as long as the indoor ambient temperature sensor can collect the indoor ambient temperature and transmit it to the air conditioner. controller can be used. In addition, since the human face is generally exposed, and the temperature of the human face can better reflect the overall comfort of the human body, the human body surface temperature is preferably the human face temperature. Of course, the human body surface temperature can also be other exposed positions of the human body. For example, those skilled in the art can flexibly set the specific temperature collection position of the human body surface temperature in practical applications, as long as the human body surface temperature can be obtained.

Preferably, the step of "selectively adjusting the air supply temperature of the air conditioner according to the human body surface temperature and the indoor ambient temperature" specifically includes: comparing the difference between the human body surface temperature and the indoor ambient temperature with the first preset temperature value; if If the difference between the human body surface temperature and the indoor ambient temperature is greater than or equal to the first preset temperature value, the air supply temperature of the air conditioner is reduced; if the difference between the human body surface temperature and the indoor ambient temperature is less than the first preset temperature value, no Adjust the supply air temperature of the air conditioner. This control method is more suitable for hot summer. When the surface temperature of the human body is much higher than the indoor ambient temperature, it is determined that the user is hot, and the air conditioner needs to reduce the air supply temperature. If the surface temperature of the human body is not much higher than the indoor ambient temperature, The air conditioner does not need to adjust the supply air temperature. Wherein, in this embodiment, the first preset temperature value may be 8°C, 9°C or 10°C, etc. Those skilled in the art can flexibly set the specific temperature of the first preset temperature value in practical applications, as long as they can It can be determined whether the air conditioner needs to adjust the supply air temperature through the temperature boundary point determined by the first preset temperature value.

Preferably, the control method of the present invention can also be applied in cold winter. For example, the step of “selectively adjusting the air supply temperature of the air conditioner according to the surface temperature of the human body and the temperature of the indoor environment” specifically includes: comparing the surface temperature of the human body with the indoor environment temperature. Temperature comparison; if the human body surface temperature is lower than the indoor ambient temperature, the air conditioner needs to increase the supply air temperature; if the human body surface temperature is not lower than the indoor ambient temperature, the air conditioner does not need to adjust the supply air temperature. That is, when the surface temperature of the human body is too low, the air conditioner needs to increase the temperature of the supply air 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 temperature of the supply air. Of course, the above-mentioned way of directly comparing the human body surface temperature with the indoor ambient temperature is only exemplary. In practical applications, the difference between the human body surface temperature and the indoor ambient temperature can also be compared with a set value, or the human body surface temperature can be compared with a set value. The ratio of the temperature to the indoor ambient temperature is compared with a set value, and those skilled in the art can flexibly set the comparison method between the human body surface temperature and the indoor ambient temperature in practical applications. In addition, the control method of the present invention can be applied to other seasons or environments in addition to the above-mentioned hot summer and cold winter, and different control strategies can be set. It should be noted that as long as the human body surface temperature and The technical solutions for judging whether to adjust the supply air temperature based on the two parameters of the indoor ambient 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 human body surface temperature and the indoor ambient temperature" specifically includes: acquiring the outdoor ambient temperature; Adjust the supply air temperature of the air conditioner. Specifically, the step of “selectively adjusting the air supply temperature of the air conditioner according to the human body surface temperature, the indoor ambient temperature and the outdoor ambient temperature” specifically includes: comparing the difference between the human body surface temperature and the indoor ambient temperature with the first preset temperature value comparison, and compare the difference between the outdoor ambient temperature and the indoor ambient temperature with the second preset temperature value; if the difference between the human body surface temperature and the indoor ambient temperature is greater than or equal to the first preset temperature value, and the outdoor ambient temperature If the difference from the indoor ambient temperature is greater than or equal to the second preset temperature value, reduce the air supply temperature of the air conditioner; if the difference between the human body surface temperature and the indoor ambient temperature is less than the first preset temperature value, or the outdoor ambient temperature If the difference between the indoor ambient temperatures is smaller than the second preset temperature value, the air supply temperature of the air conditioner is not adjusted. This control method is also more suitable for hot summer. In this case, the air conditioner will only recognize the human body when the surface temperature of the human body is significantly different from the indoor ambient temperature and the outdoor ambient temperature is relatively different from the indoor ambient temperature. A cooler temperature environment is required. At this time, the air conditioner needs to reduce the supply air temperature, and when the human body surface temperature is not much different from the indoor ambient temperature or the outdoor ambient temperature is not much different from the indoor ambient temperature, the air conditioner will determine At this time, people are already in a relatively suitable temperature environment, so the supply air temperature will not be adjusted. Similar to the above, the control method of this embodiment can also be applied to different seasons or environments, as long as the corresponding control logic is formulated, and the specific comparison method of the human body surface temperature, the indoor ambient temperature and the outdoor ambient temperature can also be flexible. Setting, it should be noted that as long as the technical scheme of determining whether to adjust the supply air temperature by adding the outdoor environmental temperature parameter on the basis of the two parameters of the human body surface temperature and the indoor environmental temperature should be limited to the protection of the present invention within the range. Wherein, in this embodiment, the first preset temperature value may be 8°C, 9°C, or 10°C, etc., and the second preset temperature value may be 10°C, 12°C, or 15°C, etc., and those skilled in the art can In practical applications, the specific temperature of the first preset temperature value and the second preset temperature value can be flexibly set, as long as the temperature boundary point jointly determined by the first preset temperature value and the second preset temperature value can be used to determine whether the air conditioner is The supply air temperature needs to be adjusted.

Preferably, during the air supply process of the air conditioner, the control method of the present invention further comprises: identifying the facial features of the human body; obtaining the age of the person based on the facial features of the human body; if the age of the person is greater than or equal to the first preset value, the air conditioner Enter the air supply automatic avoidance mode; if the age of the person is less than the first preset value and greater than the second preset value, the air conditioner enters the air supply automatic follow mode; if the age of the person is less than or equal to the second preset value, the air conditioner The device enters the air supply automatic avoidance mode. Among them, to identify the facial features of the human body, an image acquisition device (such as a camera, a video camera, etc.) can be used to collect the facial image of the human body, and then the data of the facial image of the human body can be transmitted to the controller of the air conditioner for analysis and processing, so that according to the facial features of the human body (such as face color, hair color and/or wrinkle length, etc.) to get the age of the person, and then according to the age of the person, the air conditioner is put into the air supply automatic avoidance mode/air supply automatic follow mode. Among them, the first preset value and the second preset value can divide the age of the person into three segments, the first segment (that is, the age of the person is greater than or equal to the first preset value) is the elderly, and the second segment (that is, the age of the person is greater than or equal to the first preset value). age is less than the first preset value and greater than the second preset value) is young or middle-aged, and the third segment (that is, the age of the person is less than or equal to the second preset value) is children. Because the physique of the elderly and children is slightly weaker, the air conditioner should adopt the automatic avoidance mode of air supply, that is, the air conditioner will not blow directly toward the place with the elderly and children, while the young and middle-aged have a strong physique, that is, the air conditioner will face the There are young and middle-aged places where air is concentrated. The realization of the air supply automatic avoidance mode and the air supply automatic follow mode of the air conditioner can be realized by relying on the vertical wind deflector and the horizontal wind deflector in the prior art, which will not be repeated here. In addition, the first preset value may be 65 years old, and the second preset value may be 15 years old, that is, a person whose age is greater than or equal to 65 years old is identified as an elderly person, less than or equal to 15 years old as a child, less than 65 years old and greater than 15 years old The age is identified as young or middle-aged. Of course, the above-mentioned first preset value and second preset value are only exemplary, and those skilled in the art can flexibly set the first preset value and the second preset value in practical applications. The specific age value of the value can be determined as long as the age cutoff point determined by the first preset value and the second preset value can enable the air conditioner to determine whether to enter the air supply automatic avoidance mode or the air supply automatic follow mode.

Preferably, before the air conditioner supplies air, the control method further includes: acquiring the body surface temperature and the air outlet temperature of the air conditioner; if the difference between the body surface temperature and the air outlet temperature of the air conditioner is greater than or equal to a third preset temperature value , the air conditioner will supply air; if the difference between the human body surface temperature and the air outlet temperature of the air conditioner is less than the third preset temperature value, the air conditioner will not supply air. That is, after or before the air conditioner starts to run, first collect the body surface temperature and the air outlet temperature of the air conditioner (a temperature sensor can be installed at the air outlet of the air conditioner for temperature collection). When the temperature difference of the air outlet of the air conditioner is large, the air conditioner determines that the person needs the air conditioner to supply air, and if the surface temperature of the human body is not much different from the air outlet temperature of the air conditioner, the air conditioner determines that the person does not need the air conditioner. air supply.

The technical solution of the present invention will be further described below with reference to a most preferred embodiment.

As shown in Figure 2, after the air conditioner is turned on, the temperature of the human face and the temperature of the air outlet of the air conditioner are automatically obtained; according to the temperature of the human face and the temperature of the air outlet of the air conditioner, it is judged whether the opening condition of the automatic air supply mode of the air conditioner is satisfied, that is, the temperature of the human face If the difference from the air outlet temperature of the air conditioner is greater than or equal to the third preset temperature value, the air conditioner will start the automatic air supply mode and start air supply; if the difference between the temperature of the human face and the air outlet temperature of the air conditioner is less than the third preset temperature Set the temperature value, the air conditioner does not turn on the automatic air supply mode and continues to obtain the temperature of the human face and the air outlet temperature of the air conditioner; after the automatic air supply mode is turned on, recognize the facial features of the human body; obtain the age of the person based on the facial features of the human body; if If the age of the person is greater than or equal to the first preset value (that is, the person is the elderly), the air conditioner enters the air supply automatic avoidance mode; if the age of the person is less than the first preset value and greater than the second preset value (that is, the person is young or middle-aged) Years), the air conditioner enters the air supply automatic follow mode; if the age of the person is less than or equal to the second preset value (ie, the person is a child), the air conditioner enters the air supply automatic avoidance mode. In the process of the air conditioner executing the air supply automatic follow mode or the air supply automatic avoidance mode, the temperature of the human face, the indoor ambient temperature and the outdoor ambient temperature are obtained, and whether the air conditioner automatic temperature is satisfied is determined according to the human face temperature, the indoor ambient temperature and the outdoor ambient temperature. The conditions for adjusting the supply air temperature, that is, the difference between the human face temperature and the indoor ambient temperature is greater than or equal to the first preset temperature value and the difference between the outdoor ambient temperature and the indoor ambient temperature is greater than or equal to the second preset temperature value, then the air conditioner The air conditioner automatically adjusts the supply air temperature. If the difference between the human face temperature and the indoor ambient temperature is less than the first preset temperature value or the difference between the outdoor ambient temperature and the indoor ambient temperature is less than the second preset temperature value, the air conditioner does not automatically adjust Supply air temperature and continue to obtain human face temperature, indoor ambient temperature and outdoor ambient temperature.

So far, the technical solutions of the present invention have been described with reference to the preferred embodiments shown in the accompanying drawings, however, those skilled in the art can easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
