[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] The main solution of the embodiment of the present invention is: when the air conditioner starts the fresh air mode, obtain the oxygen consumption of the space affected by the air conditioner after the air conditioner is turned on; determine the target speed of the fresh air fan of the air conditioner according to the oxygen consumption; control the fresh air fan to operate at the target speed.

[0040] In the prior art, after the air conditioner starts the fresh air mode, the operation gear of the fresh air fan of the air conditioner is generally adjusted based on the indoor scene data or air quality data detected in real time by the detection module provided on the air conditioner. However, the data detected in real time cannot reflect the overall consumption of oxygen in the room, and it is easy to cause the fresh air volume introduced by the air conditioner to be unable to restore the indoor environment to the state before the reduction of the indoor oxygen content for a long time, affecting user comfort.

[0041] The present invention provides the above solution to ensure that the fresh air volume introduced by the air conditioner can quickly and accurately restore the indoor environment to the state before the reduction of the indoor oxygen content, improving the comfort of indoor users.

[0042] The embodiment of the present invention proposes an air conditioner. The air conditioner can be any air conditioner such as a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling-mounted air conditioner, a mobile air conditioner, etc.

[0043] In the embodiment of the present invention, referring to Figure 1 , the air conditioner includes a fresh air fan 1 and a control device. The control device is connected to the fresh air fan 1, and the control device can be used to control the operation of the fresh air fan 1.

[0044] Further, referring to Figure 1 , the air conditioner further includes a human body detection module 2, such as a radar, an infrared sensor, etc. The human body detection module 2 can be used to detect human body information (such as the number of people, etc.) in the space affected by the air conditioner. The human body detection module 2 is connected to the control device, and the control device can obtain the detection data of the human body detection module 2.

[0045] Further, the air conditioner may further include a barometric pressure sensor, and the barometric pressure sensor can be used to detect indoor barometric pressure data. The barometric pressure sensor is connected to the control device, and the control device can obtain the data detected by the barometric pressure sensor.

[0046] Specifically, in the embodiment of the present invention, referring to Figure 1 , the control device includes: a processor 1001 (such as a CPU), a memory 1002, a timer 1003, etc. The memory 1002 can be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0047] Those skilled in the art can understand, Figure 1The device structure shown does not constitute a limitation on the device, and it may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0048] As Figure 1 shown, the memory 1002, which is a computer-readable storage medium, may include a control program for the air conditioner. In Figure 1 the device shown, the processor 1001 may be used to call the control program for the air conditioner stored in the memory 1002 and perform the relevant step operations of the air conditioner control method in the following embodiments.

[0049] An embodiment of the present invention also provides an air conditioner control method applied to the above air conditioner.

[0050] Referring to Figure 2 , an embodiment of the air conditioner control method of the present application is proposed. In this embodiment, the air conditioner control method includes:

[0051] Step S10, when the fresh air mode of the air conditioner is started, obtain the oxygen consumption of the space where the air conditioner acts after the air conditioner is turned on;

[0052] The oxygen consumption specifically refers to the reduction in the oxygen in the space where the air conditioner acts from the moment when the air conditioner is turned on to the moment when the fresh air mode is started.

[0053] The oxygen consumption can be obtained by analyzing the indoor state data monitored by the detection module provided on the air conditioner, or by analyzing the data detected by the detection device outside the air conditioner, or by analyzing the data input by the user.

[0054] Step S20, determine the target speed of the fresh air fan of the air conditioner according to the oxygen consumption;

[0055] The target speed can be a speed value or a speed range.

[0056] Among them, the speed of the fresh air fan is different for different fresh air gears, and there is a positive correlation between the fresh air gear and the speed of the fresh air fan. The larger the fresh air gear, the greater the speed of the fresh air fan. Based on this, the corresponding fresh air gear can be determined based on the oxygen consumption as the target speed here.

[0057] Different oxygen consumptions correspond to different target speeds of the fresh air fan. The target speed of the fresh air fan increases as the oxygen consumption increases; conversely, the target speed decreases as the oxygen consumption decreases.

[0058] Specifically, a conversion formula between oxygen consumption and the target rotational speed can be preset in advance. Based on this formula, the target rotational speed can be calculated through the oxygen consumption; alternatively, a mapping relation table can be preset in advance. The mapping relation table can include multiple oxygen consumptions and the rotational speed values respectively corresponding to each oxygen consumption. Based on this, the current oxygen consumption can be used to query the mapping relation table, and the rotational speed value matching the oxygen consumption can be used as the target rotational speed of the fresh air fan; a machine learning model representing the relationship between oxygen consumption and the target rotational speed can also be established in advance. The oxygen consumption is input into the machine learning model, and the result output by the machine learning model is used as the target rotational speed, and so on.

[0059] Step S30, control the fresh air fan to operate at the target rotational speed.

[0060] The target rotational speed can be the rotational speed value at which the fresh air fan continuously operates in the fresh air mode, or the initial rotational speed value at the start-up stage in the fresh air mode.

[0061] Based on this, in the fresh air mode, the fresh air fan can be controlled to maintain operation at the target rotational speed; or the fresh air fan can be controlled to operate at the target rotational speed for a preset duration and then the operation rotational speed of the fresh air fan can be adjusted according to factors such as oxygen concentration, pollutant concentration, or number of people.

[0062] A control method for an air conditioner proposed in an embodiment of the present invention. When the fresh air mode of the air conditioner is started, the operation rotational speed of the fresh air fan of the air conditioner is regulated based on the oxygen consumption of the indoor environment after the air conditioner is turned on. Since the user generally closes the doors and windows to enclose the indoor space when turning on the air conditioner, the turning on of the air conditioner can represent the starting moment of the decrease in the oxygen content in the indoor environment. Based on this, the oxygen consumption of the indoor environment after the air conditioner is turned on can accurately represent the overall consumption situation of the indoor oxygen in the indoor environment. Therefore, the fresh air fan adapted to control based on this oxygen consumption can introduce sufficient fresh air volume to effectively make up for the oxygen volume lost in the indoor environment after the air conditioner is turned on, ensuring that the fresh air volume introduced by the air conditioner can quickly and accurately restore the indoor environment to the state before the indoor oxygen content decreases, and improving the comfort of indoor users.

[0063] Further, based on the above embodiment, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, referring to Figure 3 , the step of obtaining the oxygen consumption of the space where the air conditioner acts after the air conditioner is turned on includes:

[0064] Step S11, obtain the size parameters, number of people, and the power-on duration of the air conditioner of the space where the air conditioner acts;

[0065] The size parameters can specifically include characteristic parameters such as volume or area that represent the size of the space where the air conditioner acts.

[0066] The size parameter and the number of people can be detected by a detection module set on the air conditioner, or obtained by acquiring the parameters input by the user.

[0067] The startup duration specifically refers to the duration from when the air conditioner is turned on to the moment when the current fresh air mode is started. Specifically, the startup duration can be timed by a timer in the control device of the air conditioner starting from when the air conditioner is turned on, and the timing data of the timer can be used as the startup duration here.

[0068] Step S12: Determine the oxygen consumption based on the size parameter, the number of people, and the startup duration.

[0069] Different size parameters, numbers of people, and startup durations correspond to different oxygen consumptions. In this embodiment, the oxygen consumption here can be calculated through a preset formula based on the size parameter, the number of people, and the startup duration. In other embodiments, the corresponding oxygen consumption values can also be determined respectively based on the size parameter, the number of people, and the startup duration, and then the oxygen consumption here can be comprehensively calculated through the three obtained oxygen consumption values, and so on.

[0070] In this embodiment, due to the different sizes of the space, the different numbers of people in the space, and the different startup durations of the air conditioner, the oxygen consumption situation in the space after the air conditioner is turned on is different. Based on this, determining the oxygen consumption by comprehensively considering the size parameter, the number of people, and the startup duration can ensure the accuracy of the determined oxygen consumption, effectively improve the accuracy of the fresh air fan regulation of the air conditioner, ensure that the fresh air volume introduced by the air conditioner can quickly and accurately restore the indoor environment to the state before the air conditioner is turned on, and further improve the comfort of indoor users.

[0071] Further, in this embodiment, referring to Figure 4 , step S12 includes:

[0072] Step S121: Determine the rate of oxygen consumption in the space where the air conditioner acts based on the size parameter and the number of people;

[0073] Different size parameters and different numbers of people correspond to different rates of oxygen consumption. Specifically, the rate shows a decreasing trend as the size parameter increases, and the rate shows an increasing trend as the number of people increases; conversely, specifically, the rate shows an increasing trend as the size parameter decreases, and the rate shows a decreasing trend as the number of people decreases. Based on this, the rate here can be calculated or the mapping relationship can be queried through the size parameter and the number of people.

[0074] In this embodiment, the size parameter is the volume of the space where the air conditioner acts. The step of determining the oxygen consumption rate in the space where the air conditioner acts according to the size parameter and the number of people includes: determining the total oxygen consumption of the people in the space where the air conditioner acts according to the preset oxygen consumption per unit person and the number of people; determining the rate according to the ratio of the total oxygen consumption to the volume. The preset oxygen consumption per unit person is specifically the amount of oxygen required for a person's physiological functions per unit time set in advance. Specifically, in this embodiment, the product of the preset oxygen consumption per unit person and the number of people is used as the total oxygen consumption here. The more the number of people, the more the total oxygen consumption. The ratio of the total oxygen consumption to the volume is directly used as the rate. In other embodiments, after obtaining the ratio of the total oxygen consumption to the volume, the rate here can also be obtained by correcting the ratio with a certain correction value.

[0075] In addition, the size parameter can also be the area. The total oxygen consumption of the people indoors can be determined based on the number of people, and the ratio of the total oxygen consumption to the area is used as the oxygen consumption rate here, or the result of correcting the ratio of the preset total oxygen consumption to the area with a preset correction value is used as the oxygen consumption rate here.

[0076] Step S122, determining the oxygen consumption according to the rate and the startup duration.

[0077] Different rates and different startup durations correspond to different oxygen consumptions. In this embodiment, a calculation formula between the rate, the startup duration, and the oxygen consumption is preset in advance, and the oxygen consumption can be calculated through the rate and the startup duration. Specifically, the product of the rate and the startup duration can be used as the oxygen consumption; or the result of further correcting the product of the rate and the startup duration can be used as the oxygen consumption. In other embodiments, the corresponding relationship between the rate, the startup duration, and the oxygen consumption can also be a mapping table, and the result obtained by querying the mapping table through the rate and the startup duration is used as the oxygen consumption.

[0078] In this embodiment, after the air conditioner is turned on, it can be considered that the indoor environment is in a relatively closed state. The size parameter of the space and the number of people can accurately reflect the speed of oxygen consumption indoors after the air conditioner is turned on. Based on this, first determine the oxygen consumption rate in the space through the size parameter and the number of people, and then further determine the oxygen consumption after the air conditioner is turned on through the oxygen consumption rate and the startup duration, which can effectively improve the accuracy of the determined oxygen consumption, and further ensure that the fresh air volume introduced by the air conditioner can quickly and accurately restore the indoor environment to the state before the air conditioner is turned on, improving the comfort of indoor users. Among them, determining the rate based on the ratio of the total oxygen consumption of the people determined based on the number of people to the volume can ensure that the determined rate can accurately reflect the speed of oxygen consumption of the people in the closed space where the air conditioner acts, so as to further improve the accuracy of the total oxygen consumption determined based on the rate and the startup duration.

[0079] Further, in this embodiment, the step of determining the oxygen consumption according to the rate and the startup duration includes: obtaining the indoor air pressure change parameter after the air conditioner is turned on; determining the oxygen consumption according to the rate, the startup duration, and the indoor air pressure change parameter.

[0080] The indoor air pressure change parameter can be specifically obtained according to the air pressure data detected by the above-mentioned air pressure sensor of the air conditioner.

[0081] The indoor air pressure change parameter can include parameters such as the air pressure change amount, the air pressure change curve, or the air pressure change rate, etc., which characterize the indoor air pressure change situation. Among them, the air pressure change curve specifically characterizes the change of the indoor air pressure value over time during the startup duration of the air conditioner.

[0082] Specifically, the indoor air pressure value detected by the air pressure sensor can be continuously obtained from the start of the air conditioner being turned on, and an air pressure change curve can be generated based on the continuously obtained data. In addition, the first air pressure value detected by the air pressure sensor can be obtained when the air conditioner is turned on, and the second air pressure value detected by the air pressure sensor can be obtained when the fresh air mode is turned on. The air pressure difference between the first air pressure value and the second air pressure value can be determined, and the air pressure difference can be used as the air pressure change amount. The ratio of the air pressure difference to the startup duration can also be used as the air pressure change rate here.

[0083] Specifically, the oxygen consumption here can be comprehensively calculated through the rate, the startup duration, and the indoor air pressure change parameter; or the first oxygen consumption can be determined through the rate and the startup duration, the second oxygen consumption can be determined according to the air pressure change parameter, and the sum of the first oxygen consumption and the second oxygen consumption can be used as the oxygen consumption of the space after the air conditioner is turned on.

[0084] In this embodiment, the product of the rate and the startup duration is determined as the initial oxygen consumption, and the correction value of the initial oxygen consumption is determined according to the indoor air pressure change parameter; the initial oxygen consumption is corrected according to the correction value to obtain the oxygen consumption. Among them, the larger the indoor air pressure change parameter is, the greater the correction amplitude of the initial oxygen consumption corresponding to the correction value is. Specifically, the correction value can be a correction amplitude or a correction coefficient, etc. Specifically, when the correction value is the correction amplitude, if the current indoor air pressure is less than the indoor air pressure when the air conditioner is turned on, the sum of the initial oxygen consumption and the correction value can be used as the oxygen consumption; if the current indoor air pressure is greater than the indoor air pressure when the air conditioner is turned on, the difference between the initial oxygen consumption and the correction value can be used as the oxygen consumption. In addition, when the correction value is the correction coefficient, the product of the initial oxygen consumption and the correction value can be used as the oxygen consumption.

[0085] In this embodiment, the indoor air pressure change parameter can reflect the change in the airtightness of the space affected by the air conditioner after it is turned on. Based on this, using the correction value determined in combination with the indoor air pressure change parameter for the result of the initial oxygen consumption as the oxygen consumption is conducive to further improving the accuracy of the determined oxygen consumption, thereby further ensuring that the fresh air volume introduced by the air conditioner can quickly and accurately restore the indoor environment to the state before the air conditioner was turned on, and further improving the comfort of indoor users.

[0086] Further, based on any of the above embodiments, after step S30, it further includes: when the fresh air fan operates at the target speed for a duration greater than or equal to a preset duration, obtaining the opening duration of the fresh air mode; reducing the operating speed of the fresh air fan according to the opening duration and the oxygen consumption. Different opening durations and oxygen consumptions correspond to different speed adjustment amounts or speed adjustment rates of the fresh air fan. Specifically, the speed adjustment amount shows an increasing trend as the opening duration increases, and the speed adjustment amount shows a decreasing trend as the oxygen consumption increases. The speed adjustment rate shows an increasing trend as the opening duration increases, and the speed adjustment rate shows a decreasing trend as the oxygen consumption increases. Specifically, the speed adjustment parameter here can be calculated through the opening duration and the oxygen consumption; the speed adjustment parameter here can also be obtained by querying a mapping table through the opening duration and the oxygen consumption. Control the fresh air fan to reduce its operating speed based on the determined speed adjustment parameter.

[0087] In this embodiment, when the fresh air fan operates at the target speed for a duration greater than or equal to a preset duration, it can be considered that the fresh air volume introduced by the air conditioner at this time is sufficient to restore the indoor space to the comfortable state before the air conditioner was turned on. Then, further reduce the operating speed of the fresh air fan based on the opening duration and the oxygen consumption, so as to ensure that the oxygen saturation in the indoor environment can be accurately maintained at the state before the air conditioner was turned on while saving the energy consumption of the fresh air fan.

[0088] Further, for better understanding, the following uses a specific application to illustrate the related technical solutions of the control method of the air conditioner involved in the embodiments of the present invention:
