Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to control methods, devices and air conditioners for air conditioners. Background Technology

[0002] Currently, with the continuous development of the economy and the increasing consumption levels of residents, people's demand for air conditioners is growing. As air conditioning technology matures, people's requirements for air conditioners are also rising. When existing air conditioners are cooling, heating, or blowing air, if a user is in a fixed position and directly exposed to the airflow for a prolonged period, the air guide vanes repeatedly oscillate in a fixed position with a fixed cycle. This reduces the user's physical sensation and can easily lead to mental fatigue, thus lowering the user's air conditioning experience. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a control method, device and air conditioner for an air conditioner, so as to alleviate the above problems and bring users a more comfortable natural wind air conditioning experience.

[0004] In a first aspect, embodiments of the present invention provide a control method for an air conditioner, comprising: when the air conditioner is running in a specified basic mode, if an activation command for a natural airflow function mode is received, controlling the air conditioner to run in the natural airflow function mode; wherein, the specified basic mode is a cooling mode, a heating mode, or a ventilation mode; the natural airflow function mode is used to characterize a mode that randomly adjusts the airflow direction of the air conditioner to provide the user with a natural airflow experience; in the natural airflow function mode, a fluctuation oscillation frequency at the current moment is determined based on a preset oscillation frequency and a random number at the current moment; at the current moment, controlling the air guide vane of the air conditioner to oscillate back and forth according to the corresponding fluctuation oscillation frequency to adjust the airflow direction of the air conditioner.

[0005] The control method of the aforementioned air conditioner, in the natural wind direction function mode, determines the corresponding fluctuation oscillation frequency based on the random number at each moment and the preset oscillation frequency, and controls the air guide plate to oscillate back and forth according to the corresponding fluctuation oscillation frequency at each moment. Since the fluctuation oscillation frequency at each moment changes randomly, the period of a single oscillation of the air guide plate also changes randomly, that is, the air guide plate exhibits irregular oscillation, which causes the airflow direction of the air blown out by the air conditioner to change irregularly. At the same time, during the oscillation of the air guide plate, the fluctuation frequency of the outlet air speed changes with the change of the fluctuation oscillation frequency of the air guide plate. The irregularly changing airflow direction and air speed cause irregular changes in the convection state between the outlet air and the indoor air, thereby allowing users to obtain a natural wind experience, alleviating the problem of poor user experience caused by the conventional oscillation of the air guide plate according to a fixed period in existing systems, and thus improving the user's air conditioning comfort.

[0006] Preferably, the above method further includes: calculating the fluctuation oscillation frequency at the current moment according to the following formula:

[0007]

[0008] Among them, f n Y represents the current oscillation frequency, f0 represents the preset oscillation frequency, and Y represents the oscillation frequency. n Let |k*Y| represent the random number at the current moment, n≥1, where n is an integer, k represents the multiplier, and |k*Y| represents the multiplier coefficient. n | represents the k*Y n Round down.

[0009] Preferably, the above method further includes: obtaining a random number from the previous moment, and calculating a random number for the current moment based on the fluctuation coefficient and the random number from the previous moment; wherein, the random number for the current moment is calculated according to the following formula:

[0010]

[0011] Among them, Y n Y represents the random number at the current moment, μ represents the fluctuation coefficient, and Y represents the random number at the current moment. n-1 Let Y represent the random number from the previous time step, and -1 ≤ Y. n-1 ≤1; n≥1, and n is an integer.

[0012] Preferably, the value range of f0 is 20Hz to 40Hz, and the value range of μ is 1.7 to 1.9.

[0013] Preferably, the step of controlling the air guide plate of the air conditioner to reciprocate according to the corresponding oscillation frequency includes: controlling the air guide plate to reciprocate at the initial position corresponding to the specified basic mode according to the preset oscillation angle and the corresponding oscillation frequency.

[0014] Preferably, the initial position includes a first initial position and a second initial position; the step of controlling the air guide plate to reciprocate at the initial position corresponding to the specified basic mode according to a preset swing angle and a corresponding wave swing frequency includes: if the specified basic mode is a heating mode, controlling the air guide plate to reciprocate at the first initial position according to a preset swing angle and a corresponding wave swing frequency; if the specified basic mode is a cooling mode or a ventilation mode, controlling the air guide plate to reciprocate at the second initial position according to a preset swing angle and a corresponding wave swing frequency; wherein, the first initial position is lower than the second initial position.

[0015] Preferably, the above method further includes: if a command to close the natural wind direction function mode is received, controlling the wind guide plate to reciprocate at the initial position corresponding to the specified basic mode according to a preset swing angle and a preset swing frequency.

[0016] Secondly, embodiments of the present invention also provide a control device for an air conditioner, comprising: an acquisition module, configured to, when the air conditioner is running in a specified basic mode, if an activation command for a natural wind direction function mode is acquired, control the air conditioner to operate in the natural wind direction function mode; wherein the specified basic mode is a cooling mode, a heating mode, or a ventilation mode; the natural wind direction function mode is used to characterize a mode that randomly adjusts the direction of the airflow blown out by the air conditioner to provide the user with a natural wind experience; a determination module, configured to, in the natural wind direction function mode, determine the fluctuation oscillation frequency at the current moment based on a preset oscillation frequency and a random number at the current moment; and an adjustment module, configured to, at the current moment, control the air guide vane of the air conditioner to oscillate back and forth according to the corresponding fluctuation oscillation frequency to adjust the direction of the airflow blown out by the air conditioner.

[0017] Thirdly, embodiments of the present invention also provide an air conditioner, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the control method for the air conditioner described in the first aspect.

[0018] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program, which, when executed by a processor, performs the steps of the air conditioner control method described in the first aspect.

[0019] The embodiments of the present invention bring the following beneficial effects:

[0020] This invention provides a control method, device, and air conditioner for an air conditioner. In the natural wind direction function mode, a corresponding fluctuation oscillation frequency is determined based on a random number at each moment and a preset oscillation frequency. The air guide plate is then controlled to oscillate back and forth according to the corresponding fluctuation oscillation frequency at each moment. Since the fluctuation oscillation frequency changes randomly at each moment, the period of a single oscillation of the air guide plate also changes randomly, i.e., the air guide plate exhibits irregular oscillation, resulting in irregular changes in the direction of the airflow blown out by the air conditioner. At the same time, during the oscillation of the air guide plate, the fluctuation frequency of the outlet air speed changes with the change of the air guide plate fluctuation oscillation frequency. The irregular changes in air direction and air speed cause irregular changes in the convection state between the outlet air and the indoor air, thereby allowing users to obtain a natural wind experience. This alleviates the problem of poor user experience caused by the conventional oscillation of the air guide plate according to a fixed period in existing systems, and thus improves the user's air conditioning comfort.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To facilitate understanding of this embodiment, the embodiments of the present invention will be described in detail below.

[0034] Example 1:

[0035] This invention provides a control method for an air conditioner, such as... Figure 1 As shown, the method includes the following steps:

[0036] Step S102: When the air conditioner is running in the specified basic mode, if the natural wind direction function mode is activated, the air conditioner is controlled to run in the natural wind direction function mode.

[0037] Specifically, the basic mode is specified as cooling mode, heating mode, or air supply mode; that is, when the air conditioner is running in cooling mode, heating mode, or air supply mode, if it receives a command from the user to activate the natural airflow function mode via the air conditioner remote control or mobile phone, the air conditioner will be controlled to run in the natural airflow function mode.

[0038] The Natural Wind Direction mode is used to characterize the irregular adjustment of the airflow direction from the air conditioner to provide users with a natural wind experience. Specifically, when the air conditioner is cooling, heating, or blowing air, the Natural Wind Direction mode controls the air guide vane to oscillate irregularly, causing the airflow direction to change irregularly. At the same time, during the oscillation of the air guide vane, the fluctuation frequency of the airflow speed changes with the oscillation frequency of the air guide vane. The irregular changes in airflow direction and speed cause irregular changes in the convection state between the airflow and the indoor air, thus providing users with a natural wind experience.

[0039] In practical applications, based on the relationship between power spectral density change and frequency, signals in nature are roughly divided into three categories: white noise, pink noise, and Brownian noise; among them, white noise can also be referred to as 1 / f 0 A signal is an irregular, irritating signal; such as the hissing sound of a television or radio when there is no signal, and various background noises. The power spectral density of this type of noise is independent of frequency. Pink noise, also known as a 1 / f signal, is a signal that brings harmony, beauty, and relaxation, such as a gentle breeze, a mountain stream, and soft, soothing music. Its power spectral density is inversely proportional to frequency f. Brownian noise can also be called 1 / f. 2 The signal is a completely rigid and monotonous signal; the power spectral density of this type of noise is related to f. 2 Inversely proportional. Therefore, the natural wind achieved through the above-mentioned natural wind direction function mode can also be called the natural breeze of the 1 / f signal, which alleviates the problem of poor user experience caused by the conventional reciprocating oscillation of the existing air guide plate according to a fixed cycle, thereby improving the user's air conditioning comfort.

[0040] Step S104: In the natural wind direction function mode, determine the fluctuation oscillation frequency at the current moment based on the preset oscillation frequency and the random number at the current moment.

[0041] To ensure the natural wind effect of the air conditioner, in the natural wind direction function mode, the controller periodically calculates the fluctuation oscillation frequency f at each moment according to a preset duration. For ease of explanation, the current moment n is used as an example here; other moments can be referred to the current moment. The embodiments of the present invention will not be described in detail here.

[0042] Specifically, for the current time n, the fluctuation oscillation frequency at the current time is calculated based on the random number at this time and the preset oscillation frequency, so as to control the air guide plate to oscillate back and forth at the corresponding fluctuation oscillation frequency at the current time. Since the fluctuation oscillation frequency changes randomly at each time, the period of a single reciprocating oscillation of the air guide plate also changes randomly. The air guide plate exhibits irregular reciprocating oscillation. Compared with the conventional fixed frequency oscillation, the irregular reciprocating oscillation causes the airflow direction of the air blown out by the air conditioner to change irregularly. At the same time, during the oscillation of the air guide plate, the fluctuation frequency of the air outlet speed changes with the change of the fluctuation oscillation frequency of the air guide plate. The irregularly changing airflow direction and speed cause the convection state between the air outlet and the indoor air to change irregularly, thereby allowing the user to obtain the experience of natural wind.

[0043] The fluctuation frequency at the current moment can be calculated using the following formula:

[0044]

[0045] Among them, f n Y represents the current oscillation frequency, f0 represents the preset oscillation frequency, and Y represents the oscillation frequency. n Let |k*Y represent the random number at the current moment, n≥1, where n is an integer, and k represents the multiplier coefficient, which can be 1, 3, 4, 5, or 6, preferably k=4; n | represents the k*Y n Rounding up involves taking the integer part and canceling out the decimal part.

[0046] It should be noted that the preset oscillation frequency f0 mentioned above can be the user-defined oscillation frequency of the air guide vane, or the default oscillation frequency of the air guide vane of the air conditioner. In practical applications, the value of f0 ranges from 20Hz to 40Hz, preferably 30Hz, and can be set according to the actual situation.

[0047] In addition, for the random number at the current moment, the air conditioner also obtains the random number from the previous moment, and calculates the random number at the current moment based on the fluctuation coefficient and the random number from the previous moment. The random number at the current moment is calculated according to the following formula:

[0048]

[0049] Among them, Y n Y represents the random number at the current moment, μ represents the fluctuation coefficient, and its value ranges from 1.7 to 1.9, preferably 1.8; n-1 Let Y represent the random number from the previous time step, and -1 ≤ Y. n-1 ≤1; n≥1, and n is an integer. It should be noted that if the current time is the first time in the natural wind direction function mode, then the random number X1 of the first time satisfies -1≤Y1≤1, preferably Y1=1.

[0050] Step S106: At the current moment, control the air guide plate of the air conditioner to swing back and forth according to the corresponding fluctuation swing frequency, so as to adjust the direction of the airflow blown out by the air conditioner.

[0051] Specifically, after determining the fluctuation frequency at the current moment, the air guide plate is controlled to oscillate back and forth at the corresponding fluctuation frequency at the current moment. Since the fluctuation frequency at each moment is randomly changing, the period of a single oscillation of the air guide plate is also randomly changing, that is, the air guide plate exhibits irregular oscillation, which causes the airflow direction of the air blown out by the air conditioner to change irregularly. At the same time, during the oscillation of the air guide plate, the fluctuation frequency of the air outlet speed changes with the change of the fluctuation frequency of the air guide plate. The irregularly changing airflow direction and speed cause the convection state between the air outlet and the indoor air to change irregularly, thus bringing a natural wind experience to the user and ensuring the user's air conditioning comfort experience.

[0052] The air conditioner control method provided in this embodiment of the invention, in the natural wind direction function mode, determines the corresponding fluctuation oscillation frequency based on the random number at each moment and the preset oscillation frequency, and controls the air guide plate to oscillate back and forth according to the fluctuation oscillation frequency corresponding to each moment. Since the fluctuation oscillation frequency at each moment is randomly changing, the period of a single reciprocating oscillation of the air guide plate is also randomly changing, that is, the air guide plate exhibits irregular reciprocating oscillation, thereby causing the airflow direction of the air blown out by the air conditioner to change irregularly. At the same time, during the oscillation of the air guide plate, the fluctuation frequency of the outlet air speed changes with the change of the fluctuation oscillation frequency of the air guide plate. The irregularly changing airflow direction and air speed cause irregular changes in the convection state between the outlet air and the indoor air, thereby enabling users to obtain a natural wind experience, alleviating the problem of poor user experience caused by the conventional reciprocating oscillation of the existing air guide plate according to a fixed period, and thus improving the user's air conditioning comfort.

[0053] In practical applications, such as Figure 2 As shown, the air conditioner includes an air deflector 21; in addition, as Figure 3As shown, the air conditioner also includes an air outlet duct 22 and an air outlet 23. Airflow is blown from the air outlet duct 22 and the air outlet 23, and the direction and speed of the airflow are adjusted by the reciprocating oscillation of the air guide vane 21. For example, when the air conditioner stops working, as... Figure 3 As shown, at this time, the air guide plate 21 closes the air outlet 23, and the air conditioner cannot blow out air; when the air conditioner is working, as Figure 4 As shown, at this time, the air guide plate 21 is in the normal air supply state, that is, the air guide plate 21 is positioned in the normal air supply position. Here, the normal air supply position is the default air supply position set by the air conditioner in different operating modes. Therefore, the air guide plate has an initial position corresponding to different operating modes. The specific initial position corresponding to different operating modes can be set according to the actual situation.

[0054] In one embodiment, the process of controlling the air guide plate of the air conditioner to reciprocate according to the corresponding oscillation frequency includes: controlling the air guide plate to reciprocate at the initial position corresponding to the specified basic mode, according to the preset oscillation angle and the corresponding oscillation frequency.

[0055] The aforementioned initial positions include a first initial position and a second initial position. The first initial position represents the initial position of the air guide vane when the air conditioner is running in heating mode; the second initial position represents the initial position of the air guide vane when the air conditioner is running in cooling / ventilation mode. Therefore, when the specified base mode is heating mode, the air guide vane is controlled to oscillate back and forth at the first initial position according to a preset oscillation angle and corresponding oscillation frequency. That is, the air guide vane rotates from the first initial position by a preset oscillation angle according to the corresponding oscillation frequency, and then rotates back to the first initial position. When the specified base mode is cooling mode or ventilation mode, the air guide vane is controlled to oscillate back and forth at the second initial position according to a preset oscillation angle and corresponding oscillation frequency. That is, the air guide vane rotates from the second initial position by a preset oscillation angle according to the corresponding oscillation frequency, and then rotates back to the second initial position.

[0056] Therefore, by adjusting the oscillation frequency of the air guide plate, the air guide plate can be made to oscillate irregularly back and forth, thereby causing irregular changes in the direction of the airflow blown out by the air conditioner. The changing airflow direction allows users to experience natural wind, thus improving the user's air conditioning comfort.

[0057] It should be noted that the preset swing angle mentioned above can be the swing angle of the air guide vane set by the user, or it can be the default swing angle of the air guide vane of the air conditioner. The specific setting can be made according to the actual situation.

[0058] Specifically, for the first initial position of the air guide plate in heating mode, such as Figure 5As shown, the air guide plate 21 is tilted downwards. At this time, the angle between the air guide plate 21 and the vertical plane is set as the first angle (not shown); similarly, the second initial position of the air guide plate in cooling mode / air supply mode is as follows: Figure 6 As shown, at this time, the angle between the air guide plate 21 and the vertical plane is set as the second angle (not shown). Therefore, the first angle is smaller than the second angle, that is, the first initial position is lower than the second initial position.

[0059] Optionally, the first initial position can be the lower limit position of the air outlet when the air guide plate opens, so as to improve the effect of downward airflow in the heating mode of the air conditioner, thereby improving the user's air conditioning comfort.

[0060] In one embodiment, the method further includes: if a shutdown command for the natural wind direction function mode is received, controlling the wind deflector to reciprocate at the initial position corresponding to the specified basic mode according to a preset swing angle and a preset swing frequency.

[0061] Specifically, when the air conditioner is operating in the specified basic mode and natural airflow function mode, if a user sends a command to turn off the natural airflow function mode via the air conditioner or a mobile phone, the air conditioner will be controlled to exit the natural airflow function mode. At this time, the air conditioner will continue to operate only in the specified basic mode.

[0062] Furthermore, when the air conditioner is operating only in the designated basic mode, the air guide plate is controlled to oscillate back and forth at the initial position corresponding to the designated basic mode according to a preset oscillation angle and preset oscillation frequency. That is, if the air conditioner is operating in heating mode, the air guide plate will oscillate back and forth at the first initial position according to the preset oscillation angle and preset oscillation frequency. If it oscillates at the preset oscillation frequency, the air guide plate will rotate from the first initial position to the preset oscillation angle and preset oscillation frequency, and then rotate back to the first initial position in the opposite direction. Similarly, if the air conditioner is operating in cooling / ventilation mode, the air guide plate will oscillate back and forth at the second initial position according to the preset oscillation angle and preset oscillation frequency. If it oscillates at the preset oscillation frequency, the air guide plate will rotate from the second initial position to the preset oscillation angle, and then rotate back to the second initial position in the opposite direction. This ensures the air delivery effect of the air conditioner in the designated basic mode.

[0063] Furthermore, if, while the air conditioner is operating in the designated basic mode, it receives a command from the user to activate the natural airflow function mode via the air conditioner remote control or mobile phone, the air conditioner will operate in both the designated basic mode and the natural airflow function mode. In this case, the air conditioner meets the user's air conditioning needs, such as cooling, heating, or ventilation, by operating in the designated basic mode. Simultaneously, the air conditioner also operates in the natural airflow function mode, where the air guide vane is controlled to oscillate irregularly back and forth according to a fluctuating frequency at any given moment. Because the frequency of the oscillation is random at any given moment, the period of a single reciprocating oscillation of the air guide plate is also random. The air guide plate exhibits irregular reciprocating oscillation. Compared with the regular fixed oscillation frequency, the irregular reciprocating oscillation causes the airflow direction of the air blown out by the air conditioner to change irregularly. At the same time, during the oscillation of the air guide plate, the frequency of the air outlet speed changes with the frequency of the air guide plate's oscillation. The irregularly changing airflow direction and speed cause the convection state between the air outlet and the indoor air to change irregularly, thus allowing users to obtain a natural wind experience.

[0064] Therefore, by specifying the basic mode and the natural wind direction function mode, in addition to meeting the user's air conditioning needs, it also provides the user with a more comfortable natural wind experience, thereby improving the user's air conditioning comfort.

[0065] Example 2:

[0066] Corresponding to the above method embodiments, this invention also provides a control device for an air conditioner, such as... Figure 7 As shown, the device includes: an acquisition module 71, a determination module 72, and an adjustment module 73; wherein the functions of each module are as follows:

[0067] The acquisition module 71 is used to control the air conditioner to operate in the natural wind direction function mode when the air conditioner is running in the specified basic mode and if the activation command of the natural wind direction function mode is obtained; wherein, the specified basic mode is the cooling mode, the heating mode, or the air supply mode; the natural wind direction function mode is used to characterize the mode of randomly adjusting the wind direction of the air blown out by the air conditioner so as to give the user a natural wind experience.

[0068] The determination module 72 is used to determine the fluctuation oscillation frequency at the current moment based on the preset oscillation frequency and the random number at the current moment in the natural wind direction function mode.

[0069] The adjustment module 73 is used to control the air guide plate of the air conditioner to swing back and forth according to the corresponding fluctuation swing frequency at the current moment, so as to adjust the direction of the airflow blown out by the air conditioner.

[0070] The control device for an air conditioner provided in this embodiment of the invention, in the natural wind direction function mode, determines the corresponding fluctuation oscillation frequency based on a random number at each moment and a preset oscillation frequency, and controls the air guide plate to oscillate back and forth according to the corresponding fluctuation oscillation frequency at each moment. Since the fluctuation oscillation frequency at each moment is randomly changing, the period of a single reciprocating oscillation of the air guide plate is also randomly changing, that is, the air guide plate exhibits irregular reciprocating oscillation, thereby causing the airflow direction of the air blown out by the air conditioner to change irregularly. At the same time, during the oscillation of the air guide plate, the fluctuation frequency of the outlet air speed changes with the change of the fluctuation oscillation frequency of the air guide plate. The irregularly changing airflow direction and air speed cause irregular changes in the convection state between the outlet air and the indoor air, thereby enabling users to obtain a natural wind experience, alleviating the problem of poor user experience caused by the conventional reciprocating oscillation of the existing air guide plate according to a fixed period, and thus improving the user's air conditioning comfort.
