Description
Technical Field

Background
Air is an essential element essential for human survival, and in recent years, air pollution has become more serious, and attention to the problem has been raised. In the indoor space, people can continuously discharge CO2 under the breathing action, and substances such as indoor furniture, decoration materials and the like can emit formaldehyde or other harmful gases to a certain extent. When the concentration of the polluted gases such as CO2, formaldehyde and the like reaches a certain degree, the human health can be damaged. For example, the human body may develop symptoms of discomfort when the volume fraction of carbon dioxide in the air exceeds 0.1%; when the concentration reaches 1%, the patients feel suffocation, dizziness and palpitation; vertigo can be felt when the content reaches 4-5 percent; over 6% of the total weight of the composition will cause confusion and gradual cessation of breathing, leading to death. In another example, formaldehyde, when reaching a certain concentration, can cause redness, itching of the eyes, discomfort or pain in the throat, hoarseness, sneezing, chest distress, asthma, dermatitis, etc. According to statistics, about 80-90% of the time spent indoors by modern people, especially by large cities, the problem of indoor air environment quality is particularly prominent.
Based on the problems, the fresh air system is mainly used for updating the air of the indoor environment at present, and the purpose of diluting and reducing the concentration of indoor pollutants is achieved.

Detailed Description
The present invention first provides a fresh air control method for an air conditioner, and fig. 1 is a schematic flow chart of a fresh air control method for an air conditioner according to an embodiment of the present invention. Referring to fig. 1, the fresh air control method of the present invention includes:
s10, acquiring air parameters and space parameters of an indoor environment where the air conditioner is located; the air parameter of the indoor environment is used for representing the indoor air quality of the indoor environment, and the space parameter of the indoor environment is used for representing the size of a space area of the indoor environment; and
and step S20, adjusting the fresh air quantity introduced into the indoor environment by the air conditioner according to the air parameters and the space parameters.
The fresh air control method of the invention jointly adjusts the fresh air quantity introduced into the indoor environment by the air conditioner according to the acquired air parameters and space parameters of the indoor environment, wherein the air parameters can represent the indoor air quality of the current indoor environment, and the space parameters can represent the size of the space area of the indoor environment to be adjusted.
Fig. 2 is a schematic flowchart of a fresh air control method for an air conditioner according to another embodiment of the present invention. In some embodiments, before obtaining the air parameter and the spatial parameter of the indoor environment where the air conditioner is located, the fresh air control method of the present invention further includes:
and S00, receiving a fresh air starting instruction for indicating the starting of the fresh air function of the air conditioner.
That is to say, the air parameters and the space parameters of the indoor environment where the air conditioner is located are obtained only after the fresh air function of the air conditioner is started, and the fresh air volume is adjusted according to the obtained air parameters and the space parameters. The invention does not acquire the air parameters and the space parameters of the indoor environment where the air conditioner is located at any time, thereby reducing the operation burden of the air conditioner.
It should be noted that, the user can automatically start the fresh air function of the air conditioner by means of a remote controller, voice, etc., and the air conditioner can also automatically start the fresh air function after meeting the preset conditions.
In some embodiments, the air parameter may specifically include one or more of a formaldehyde concentration, a carbon dioxide concentration, an inhalable particulate concentration. That is, the indoor air quality of an indoor environment may be characterized by one or more of formaldehyde concentration, carbon dioxide concentration, and respirable particulate matter concentration.
Further, the step of acquiring the air parameter of the indoor environment where the air conditioner is located may specifically include:
reading a detection result of a formaldehyde detection device for detecting a formaldehyde concentration in an indoor environment, reading a detection result of a carbon dioxide detection device for detecting a carbon dioxide concentration in an indoor environment, and/or reading a detection result of an inhalable particulate matter detection device for detecting an inhalable particulate matter concentration in an indoor environment.
In a particular embodiment, the formaldehyde detection device, the carbon dioxide detection device, and the inhalable particulate detection device may be fully or partially integrated on the air conditioner.
In another specific embodiment, the formaldehyde detection device, the carbon dioxide detection device and the inhalable particle detection device may be wholly or partially separately disposed in an indoor environment or integrated on other household equipment, and are in communication with the air conditioner for signal transmission with the air conditioner.
Specifically, the formaldehyde detection device may be a formaldehyde sensor, the carbon dioxide detection device may be a carbon dioxide sensor, and the inhalable particle detection device may be an inhalable particle sensor.
Of course, in some alternative embodiments, the air parameter may also include the concentration or amount of other harmful substances to the human body that may be present in the indoor environment.
Fig. 3 is a schematic flowchart of acquiring spatial parameters of an indoor environment in which an air conditioner is located according to an embodiment of the present invention. In some embodiments, the step of obtaining the spatial parameters of the indoor environment in which the air conditioner is located includes:
step S111, acquiring target attribute parameters of the air conditioner for expressing the model and/or the refrigerating capacity of the air conditioner;
and step S112, determining a target space parameter corresponding to the target attribute parameter according to the matching relationship between the attribute parameter and the space parameter prestored in the air conditioner.
That is, the present invention determines the space parameters of the indoor space where the air conditioner is located according to some attribute parameters of the air conditioner itself, rather than directly setting corresponding hardware devices on the air conditioner for direct acquisition. Therefore, only the existing parameters of the air conditioner are required to be read, the requirement on hardware configuration of the air conditioner is reduced, and the cost of the air conditioner is reduced.
Specifically, the air conditioner needs to store a matching relationship between the attribute parameters of the air conditioner and the spatial parameters of the indoor environment where the air conditioner is located in advance, and the matching spatial parameters can be directly determined according to the attribute parameters of the air conditioner.
Further, the target attribute parameter for representing the type of air conditioner and/or the cooling capacity may be, for example, the type of air conditioner, such as cabinet, wall-mounted, table-top, etc. This is because the cabinet type air conditioner is generally used in a living room or the like in an indoor environment having a large area, and the wall-mounted type or the desktop type air conditioner is generally used in an indoor environment having a small area such as a bedroom or a study room, and thus the model of the air conditioner can express the size of the spatial region of the indoor environment where the air conditioner is located to some extent. At this time, a matching relationship between a specific air conditioner model and the size of the spatial region of the indoor environment to which the air conditioner is applied may be preset in the air conditioner.
Further, the target attribute parameter for representing the type and/or the cooling capacity of the air conditioner may be, for example, the cooling capacity of the air conditioner or the number of matches of the air conditioner, the air conditioner with a large cooling capacity or a large number of matches is generally used in a living room or a similar indoor environment with a large area, the air conditioner with a small cooling capacity or a small number of matches is generally used in an indoor environment with a small area, such as a bedroom, a study room, and the like, and therefore the cooling capacity or the number of matches of the air conditioner can express the size of the spatial region of the indoor environment where the air conditioner is located to some extent. At this time, a matching relationship between the cooling capacity or the matching number of the air conditioner and the size of the spatial region of the indoor environment to which the air conditioner is applied may be previously set in the air conditioner.
Of course, the spatial parameters can also be determined indirectly via other parameters of the air conditioner which are related to the size of the spatial region of the indoor environment in which the air conditioner is located.
Fig. 4 is a schematic flowchart of acquiring spatial parameters of an indoor environment in which an air conditioner is located according to another embodiment of the present invention. In other embodiments, the step of obtaining the spatial parameter of the indoor environment where the air conditioner is located may specifically include:
step S121, sending an inquiry instruction to a terminal device interconnected with the air conditioner; the query instruction is used for querying the size of a space area of an indoor environment where the air conditioner is located; and
and step S122, receiving data information which is fed back by the terminal equipment according to the inquiry instruction and is used for indicating the size of the space area of the indoor environment where the air conditioner is located.
That is to say, the air conditioner may send an inquiry command to the terminal device, so that the user himself inputs the spatial parameters of the indoor environment where the air conditioner is located, instead of directly setting a corresponding hardware device on the air conditioner to directly obtain the spatial parameters. Therefore, only the air conditioner and the terminal equipment need to be interconnected, the air conditioner and the terminal equipment interconnection are commonly applied to the existing intelligent air conditioner, extra operation of a user is not needed at all, the requirement on hardware configuration of the air conditioner is lowered, the cost of the air conditioner is lowered, the spatial parameters input by the user are more accurate, and the accuracy of fresh air volume adjustment is further improved.
In still other embodiments, the air conditioner may be communicatively coupled to a sweeping robot within the indoor environment. The sweeping robot usually calculates and stores the sweeping area, and the sweeping area of the sweeping robot is similar to the plane area of the indoor environment where the air conditioner is located. Therefore, in these embodiments, referring to the schematic flowchart of fig. 5 for acquiring the spatial parameter of the indoor environment where the air conditioner is located according to another embodiment of the present invention, the step of acquiring the spatial parameter of the indoor environment where the air conditioner is located may specifically include:
step S131, sending a request instruction to a sweeping robot interconnected with an air conditioner; the request instruction is used for requesting the sweeping robot to send the sweeping area stored in the sweeping robot to the air conditioner; and
step S132, receiving data information indicating the cleaning area sent by the cleaning robot according to the request instruction.
That is, the sweeping robot can indirectly acquire the spatial parameters of the indoor environment where the air conditioner is located by sending a request instruction to the sweeping robot to make the sweeping robot feed back the sweeping area stored in the sweeping robot to the air conditioner, rather than directly acquiring the spatial parameters by directly arranging a corresponding hardware device on the air conditioner. Therefore, the air conditioner and the sweeping robot are only required to be interconnected, the requirement on hardware configuration of the air conditioner is also reduced, and the cost of the air conditioner is reduced. The sweeping robot is common household equipment, and the calculated sweeping area is very close to the plane area of the indoor environment where the air conditioner is located, so that the spatial parameter representing the indoor environment where the air conditioner is located by using the sweeping area of the sweeping robot is very accurate, and the accuracy of fresh air volume adjustment is further improved.
In still other embodiments, the air conditioner is in an intelligent home system, and the intelligent home system further includes at least one other home device storing target data representing the size of the spatial region of the indoor environment in which the intelligent home system is located. Referring to the schematic flowchart of fig. 6 for acquiring the spatial parameter of the indoor environment where the air conditioner is located according to another embodiment of the present invention, the step of acquiring the spatial parameter of the indoor environment where the air conditioner is located may specifically include:
step S141, target data which is stored in at least one other household device of the intelligent household system and used for representing the size of the space area of the indoor environment is obtained; and
and step S142, obtaining the space parameters of the indoor environment according to the target data.
That is to say, the spatial parameters of the indoor environment can be indirectly acquired through the target data of the other household devices in the smart home system where the air conditioner is located, which can represent the size of the spatial region of the indoor environment, rather than directly acquiring by setting corresponding hardware devices on the air conditioner. Therefore, only the existing data of other household equipment in the intelligent household system where the air conditioner is located need to be utilized, the requirement on hardware configuration of the air conditioner is lowered, and the cost of the air conditioner is lowered. Because the air conditioner and other household equipment are already in the same intelligent household system, the problem of interconnection between the air conditioner and other household equipment does not need to be additionally considered.
Fig. 7 is a schematic flow chart for adjusting the amount of fresh air introduced into the indoor environment by the air conditioner according to the air parameter and the space parameter according to an embodiment of the present invention. In some embodiments, the step S20 of adjusting the amount of fresh air introduced into the indoor environment by the air conditioner according to the air parameter and the spatial parameter may specifically include:
s21, determining a target fresh air volume required by the indoor environment according to the air parameters and the space parameters;
s22, setting initial operation parameters of a fresh air device of the air conditioner according to the target fresh air volume;
and S23, controlling the fresh air device to operate according to the initial operation parameters.
According to the invention, before the fresh air device is started, the target fresh air volume required by the indoor environment is determined according to the air parameters and the space parameters of the indoor environment where the air conditioner is located, then the initial operation parameters of the fresh air device are set according to the target fresh air volume, and the fresh air device is controlled to operate according to the initial operation parameters, so that the fresh air volume actually introduced by the air conditioner is consistent with the target fresh air volume as much as possible, the indoor air quality of the indoor environment is adjusted more quickly and effectively, and the use experience of a user is improved.
Specifically, the air conditioner may have a pre-stored matching relationship between the air parameter and the fresh air volume and between the spatial parameter and the fresh air volume, and a value of the fresh air volume may be uniquely determined according to the acquired air parameter and spatial parameter, which is the target fresh air volume. It can be understood that the worse the indoor air quality characterized by the air parameter, the larger the value of the fresh air volume; conversely, the smaller the value of the fresh air volume. The larger the size of the space region represented by the space parameters is, the larger the value of the fresh air volume is; conversely, the smaller the value of the fresh air volume.
Specifically, the air conditioner is also pre-stored with a matching relationship between the fresh air volume and the operation parameters of the fresh air device, and the unique operation parameters of the fresh air device can be determined according to the determined target fresh air volume, namely the unique operation parameters are the initial operation parameters.
Further, the operation parameter of the fresh air device may include at least one of a rotation speed of a fresh air fan of the fresh air device and an opening degree of a fresh air valve of the fresh air device. That is to say, the fresh air volume introduced by the fresh air device can be adjusted to the target fresh air volume by adjusting the rotating speed of the fresh air fan and/or the opening degree of the fresh air valve.
The inventor realizes that the fresh air volume actually introduced by the fresh air device may have a certain difference from the target fresh air volume due to a series of reasons such as air resistance and pressure loss. To this end, in some embodiments, referring to fig. 8, which is a schematic flow chart illustrating adjusting the amount of fresh air introduced into the indoor environment by the air conditioner according to the air parameter and the spatial parameter according to another embodiment of the present invention, after controlling the fresh air device to operate according to the initial operation parameter, the control method of the present invention further includes:
step S24, acquiring actually-measured fresh air volume actually introduced into an indoor environment; and
and S25, adjusting the operation parameters of the fresh air device according to the difference value of the target fresh air volume and the actually measured fresh air volume so as to enable the actually introduced actually measured fresh air volume to be consistent with the target fresh air volume in the indoor environment.
That is to say, the invention further detects the actually measured fresh air volume introduced into the indoor environment by the fresh air device, and further adjusts the operation parameters of the fresh air device by comparing the actually measured fresh air volume with the target fresh air volume, so that the actually introduced actual fresh air volume into the indoor environment is consistent with the target fresh air volume, and the adjustment of the fresh air volume is more accurate.
In some embodiments, the step of determining the target fresh air volume required by the indoor environment according to the air parameter and the spatial parameter may specifically include:
determining the air quality grade of the air parameter; and
calculating the target fresh air volume required by the indoor environment according to the following formula:
a = a × b × m; wherein
A represents the target fresh air volume required by the indoor environment, a represents a constant greater than zero, b represents a spatial parameter, and m represents the determined air quality level.
It should be noted that the indoor air quality of the indoor environment can be sequentially divided into a first-level air quality grade, a second-level air quality grade, a third-level air quality grade and other air quality grades according to the quality of the indoor air of the indoor environment, and the better the indoor air quality of the indoor environment is, the higher the corresponding air quality grade is, the smaller the value of the corresponding air quality grade is.
The present invention also provides an air conditioner, and fig. 9 is a schematic structural view of the air conditioner according to an embodiment of the present invention. Referring to fig. 9, the air conditioner 1 of the present invention includes a fresh air device 10 and a control device 20 connected to the fresh air device 10.
The fresh air device 10 is used for introducing outdoor fresh air into an indoor environment where the air conditioner is located. The control device 20 includes a processor 21 and a memory 22, wherein the memory 22 stores a machine-executable program 23, and the machine-executable program 23 is used for implementing the fresh air control method described in any of the above embodiments when executed by the processor 21.
