Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air conditioner control device, an air conditioner control method, an air conditioner, and a computer-readable storage medium. Background Technology

[0002] The speed at which an air conditioner cools down is largely limited by the airflow of the indoor unit and the operating frequency of the compressor. Since the current compressor frequency is limited by condensation, it is determined by strict condensation tests. The condensation frequency in the national standard is the result of a fixed frequency that has been running for a long time under constant humidity. However, in reality, room humidity is decreasing, which will slow down the temperature drop and seriously affect the user experience. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the first aspect of the present invention is to provide a control device for an air conditioner.

[0005] A second aspect of the present invention is to provide a method for controlling an air conditioner.

[0006] A third aspect of the present invention is to provide an air conditioner.

[0007] A fourth aspect of the present invention is to provide a computer-readable storage medium.

[0008] In view of this, according to a first aspect of the present invention, a control device for an air conditioner is provided, comprising: a detection component adapted to detect the ambient temperature of the space where the air conditioner is located; a memory storing a computer program; and a processor electrically connected to the detection component and the memory, wherein the processor performs the following steps when executing the computer program: determining the noise increase of the air conditioner based at least on the ambient temperature and the target temperature; and adjusting the fan speed of the air conditioner based on the noise increase.

[0009] The air conditioner control device provided by this invention detects the ambient temperature of the space where the air conditioner is located through a detection component. The processor, based on at least the ambient temperature and the target temperature, determines the amount of noise increase the air conditioner will generate when the space reaches the target temperature. It then determines whether the noise increase falls within a range imperceptible to the user based on the relationship between the noise increase and a preset noise increase threshold. This determines the appropriate fan speed increase corresponding to a reasonable decibel increase in noise, and subsequently adjusts the air conditioner's fan speed. On one hand, while meeting condensation limits, increasing the fan speed increases the cooling capacity of the air conditioner, allowing for rapid room cooling. On the other hand, the noise generated during fan speed adjustment is imperceptible to the user, achieving windless adjustment, avoiding user interference, and improving the user experience.

[0010] Specifically, the target temperature can be a preset comfort temperature or a temperature set by the user.

[0011] Furthermore, after the air conditioner is turned on, it is first determined whether the air conditioner can operate normally. If it can operate normally, the fan speed is adjusted. If it cannot operate normally, a fault is displayed to prompt the user to carry out maintenance in time.

[0012] In addition, the control device for the air conditioner according to the above-described technical solution provided by the present invention may also have the following additional technical features:

[0013] In the above technical solution, further, when the processor executes the computer program, it adjusts the fan speed of the air conditioner according to the noise increase, specifically including: comparing the noise increase and the noise increase threshold; if the noise increase is greater than or equal to the noise increase threshold, determining the air conditioner's speed offset based on the correspondence between the preset noise increase and the preset speed offset, and the noise increase threshold; or if the noise increase is less than the noise increase threshold, determining the speed offset based on the correspondence between the preset noise increase and the preset speed offset, and the noise increase; and controlling the fan speed to increase according to the speed offset.

[0014] In this technical solution, by comparing the noise increase amount with the noise increase threshold, it is determined whether the noise increase amount falls within a range that is difficult for users to perceive. If the noise increase amount is greater than or equal to the noise increase threshold, it indicates that the current noise increase amount is too large and easily noticed by the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase threshold is determined. If the noise increase amount is less than the noise increase threshold, it indicates that the current noise increase amount is small. Even if the fan speed is increased according to the target temperature, the generated noise will not have a significant impact on the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase amount is determined. After determining the speed offset amount, the fan speed is controlled to increase according to the speed offset amount to achieve rapid cooling. This not only compensates for the insufficient cooling capacity caused by the limitation of fixed frequency due to condensation, but also reasonably limits the increase in fan speed by the noise increase threshold, ensuring that the noise generated during the adjustment of fan speed is not significantly perceived by the user, thus improving the user experience.

[0015] In any of the above technical solutions, it further includes: a timer electrically connected to the processor, the timer being adapted to time the running length of the air conditioner; when the processor executes the computer program, it also performs: comparing the running length with a preset duration; and determining a noise growth threshold based on the comparison.

[0016] In this technical solution, since hearing has a certain degree of adaptability, even very small noises can be detected in a low-noise environment over a long period of time. Conversely, in a noisy environment, even a significant increase in noise will not be easily perceived. Therefore, by recording the running time of the air conditioner through a timer, the noise growth threshold, i.e., the critical value of noise growth, is determined based on the relationship between the running time and the preset duration. If the running time is greater than the preset duration, it means that the user has become accustomed to the noise generated by the air conditioner. At this time, the noise growth threshold can be appropriately increased, thereby maximizing the range of possible speed deviation and achieving better rapid cooling. The noise growth threshold and the preset duration can be reasonably set according to the noise level generated by the air conditioner and the user's needs.

[0017] Specifically, the preset duration is between 1 min and 10 min. If the runtime is longer than the preset duration, the noise growth threshold is between 0 dB and 3 dB. If the runtime is less than or equal to the preset duration, the noise growth threshold is between 0 dB and 1.5 dB.

[0018] In any of the above technical solutions, the processor, when executing the computer program, further executes the determination of the noise increase of the air conditioner based on the ambient temperature and the target temperature, specifically including: determining the temperature difference between the ambient temperature and the target temperature; and determining the noise increase corresponding to the temperature difference based on the correspondence between the preset temperature difference and the preset noise increase.

[0019] In this technical solution, the temperature difference between the ambient temperature and the target temperature is calculated. Then, based on the correspondence between the preset temperature difference and the preset noise increase, the noise increase corresponding to the temperature difference is determined. That is, the increase in noise generated when the air conditioner adjusts the temperature according to the temperature difference compared to the noise generated when the air conditioner is currently running, so as to adjust the fan speed without causing obvious user perception.

[0020] In addition, when the correspondence between the preset temperature difference and the preset noise increase is uncertain, the current fan speed of the air conditioner can be obtained, the noise value of the air conditioner can be determined based on the current fan speed, the target fan speed can be determined based on the preset temperature difference, and the noise threshold corresponding to the target fan speed can be determined. Based on the noise value and the noise threshold, the noise increase can be calculated.

[0021] In any of the above technical solutions, the processor further executes the following when executing the computer program: determining whether the temperature difference is less than the preset stop temperature; and stopping the adjustment of the fan speed when the temperature difference is determined to be less than the preset stop temperature.

[0022] In this technical solution, if the temperature difference is less than the preset stop temperature, it means that the air conditioner has almost finished adjusting the indoor temperature. At this time, the fan speed is stopped and the air conditioner operates at the normal speed to reduce the energy consumption of the air conditioner and meet the energy-saving requirements.

[0023] According to a second aspect of the present invention, a method for controlling an air conditioner is provided, comprising: detecting the ambient temperature of the space where the air conditioner is located; determining the noise increase of the air conditioner based at least on the ambient temperature and the target temperature; and adjusting the fan speed of the air conditioner based on the noise increase.

[0024] The air conditioner control method provided by this invention can detect the ambient temperature of the space where the air conditioner is located. Based on at least the ambient temperature and the target temperature, it determines the amount of noise increase the air conditioner will generate when the space reaches the target temperature. It then judges whether the noise increase falls within a range that is imperceptible to the user, thereby determining the appropriate fan speed increase corresponding to a reasonable decibel increase in noise, and subsequently adjusting the air conditioner's fan speed. On the one hand, while ensuring the air conditioning frequency meets condensation limits, increasing the cooling capacity by increasing the fan speed allows for rapid room cooling. On the other hand, the noise generated during fan speed adjustment is not noticeably perceived by the user, achieving windless adjustment, avoiding user interference, and improving the user experience.

[0025] Specifically, the target temperature can be a preset comfort temperature or a temperature set by the user.

[0026] In any of the above technical solutions, further adjusting the air conditioner's fan speed according to the noise increase specifically includes: comparing the magnitude of the noise increase and the noise increase threshold; if the noise increase is greater than or equal to the noise increase threshold, determining the air conditioner's speed offset based on the correspondence between the preset noise increase and the preset speed offset, and the noise increase threshold; or if the noise increase is less than the noise increase threshold, determining the speed offset based on the correspondence between the preset noise increase and the preset speed offset, and the noise increase; and controlling the fan speed to increase according to the speed offset.

[0027] In this technical solution, by comparing the noise increase amount with the noise increase threshold, it is determined whether the noise increase amount falls within a range that is difficult for users to perceive. If the noise increase amount is greater than or equal to the noise increase threshold, it indicates that the current noise increase amount is too large and easily noticed by the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase threshold is determined. If the noise increase amount is less than the noise increase threshold, it indicates that the current noise increase amount is small. Even if the fan speed is increased according to the target temperature, the generated noise will not have a significant impact on the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase amount is determined. After determining the speed offset amount, the fan speed is controlled to increase according to the speed offset amount to achieve rapid cooling. This not only compensates for the insufficient cooling capacity caused by the limitation of fixed frequency due to condensation, but also reasonably limits the increase in fan speed by the noise increase threshold, ensuring that the noise generated during the adjustment of fan speed is not significantly perceived by the user, thus improving the user experience.

[0028] In any of the above technical solutions, before adjusting the fan speed of the air conditioner according to the noise increase, the method further includes: obtaining the running time of the air conditioner; comparing the running time with the preset time; and determining the noise increase threshold based on the comparison.

[0029] In this technical solution, since hearing has a certain degree of adaptability, even very small noises can be detected in a low-noise environment over a long period of time. Conversely, in a noisy environment, even a significant increase in noise will not be easily perceived. Therefore, by recording the running time of the air conditioner through a timer, the noise increase threshold is determined based on the relationship between the running time and the preset duration. If the running time is greater than the preset duration, it means that the user has become accustomed to the noise generated by the air conditioner. At this time, the noise increase threshold can be appropriately increased to maximize the range of speed deviation that can be increased, thereby achieving better rapid cooling. The noise increase threshold and the preset duration can be reasonably set according to the noise level generated by the air conditioner and the user's needs.

[0030] Specifically, the preset duration is between 1 min and 10 min. If the runtime is longer than the preset duration, the noise growth threshold is between 0 dB and 3 dB. If the runtime is less than or equal to the preset duration, the noise growth threshold is between 0 dB and 1.5 dB.

[0031] In any of the above technical solutions, further, the noise increase of the air conditioner is determined based on the ambient temperature and the target temperature, specifically including: determining the temperature difference between the ambient temperature and the target temperature; and determining the noise increase corresponding to the temperature difference based on the correspondence between the preset temperature difference and the preset noise increase.

[0032] In this technical solution, the temperature difference between the ambient temperature and the target temperature is calculated. Then, based on the correspondence between the preset temperature difference and the preset noise increase, the noise increase corresponding to the temperature difference is determined. That is, the increase in noise generated when the air conditioner adjusts the temperature according to the temperature difference compared to the noise generated when the air conditioner is currently running, so as to adjust the fan speed without causing obvious user perception.

[0033] In addition, when the correspondence between the preset temperature difference and the preset noise increase is uncertain, the current fan speed of the air conditioner can be obtained, the noise value of the air conditioner can be determined based on the current fan speed, the target fan speed can be determined based on the preset temperature difference, and the noise threshold corresponding to the target fan speed can be determined. Based on the noise value and the noise threshold, the noise increase can be calculated.

[0034] In any of the above technical solutions, the method further includes: determining whether the temperature difference is less than the preset stop temperature; and stopping the adjustment of the fan speed when the temperature difference is determined to be less than the preset stop temperature.

[0035] In this technical solution, if the temperature difference is less than the preset stop temperature, it means that the air conditioner has almost finished adjusting the indoor temperature. At this time, the fan speed is stopped and the air conditioner operates at the normal speed to reduce the energy consumption of the air conditioner and meet the energy-saving requirements.

[0036] According to a third aspect of the present invention, an air conditioner is provided, comprising: a control device for an air conditioner according to any one of the above-mentioned claims, the control device being adapted to perform the following steps: detecting the ambient temperature of the space where the air conditioner is located; determining the noise increase of the air conditioner based at least on the ambient temperature and a preset temperature; and adjusting the fan speed of the air conditioner based on the noise increase.

[0037] The air conditioner provided by this invention can detect the ambient temperature of the space where the air conditioner is located. Based on at least the ambient temperature and the target temperature, it determines the amount of noise increase the air conditioner will generate when the space reaches the target temperature. It then judges whether the noise increase falls within a range that is imperceptible to the user, thereby determining the appropriate fan speed increase corresponding to a reasonable decibel increase in noise, and subsequently adjusting the air conditioner's fan speed. On the one hand, while ensuring the air conditioning frequency meets condensation limits, it can increase the cooling capacity of the air conditioner by increasing the fan speed, allowing for rapid room cooling. On the other hand, the noise generated during fan speed adjustment is not noticeably perceived by the user, achieving windless adjustment, avoiding interference with the user, and improving the user experience. Specifically, the air conditioner also includes a load, such as a fan and / or compressor.

[0038] In any of the above technical solutions, the air conditioner further includes: an air outlet; an air outlet assembly electrically connected to the control device, the air outlet assembly being adapted to adjust the airflow from the air outlet, the air outlet assembly having multiple forms; and the control device being adapted to control the air outlet assembly to switch forms according to the position information of the target object.

[0039] In this technical solution, air that has been heated by the indoor heat exchanger is blown out through the air outlet to achieve cooling or heating. The air outlet assembly can adjust the air outlet angle. The air conditioner's control device can detect the location information of the target object, which can be a human body or a preset object, such as a bed, desk, sofa, or other furniture where a person may linger. Based on the location information of the target object, the air outlet assembly is controlled to switch modes, so that the direction of the target object is in a windless state, thereby ensuring that the air supply does not blow directly on the human body and improving the comfort of the air conditioner. In areas outside the target object's location, the air supply volume can be increased by methods such as "direct blowing" to improve the cooling / heating efficiency while ensuring that the human body does not feel wind. Meanwhile, based on the absence of wind, the control device determines the amount of noise increase that the air conditioner will generate when the space reaches the target temperature, based on the ambient temperature and the target temperature. It then determines the amount of speed increase corresponding to a reasonable increase in noise in decibels and adjusts the fan speed of the air conditioner accordingly. This increases the fan speed and the air conditioner's cooling / heating capacity. Furthermore, the noise generated during the fan speed adjustment process will not be noticeably perceived by the user, thus meeting various user needs.

[0040] In any of the above technical solutions, further, the multiple forms include a first form, a second form, and a third form. The controller controls the air outlet component to switch forms according to the distance value of the target object, specifically including: obtaining a first preset distance range and a second preset distance range; determining that the distance value is within the first preset distance range, controlling the air outlet component to switch from the first form to the second form; determining that the distance value is within the second preset distance range, controlling the air outlet component to switch from the first form to the third form.

[0041] In this technical solution, the first mode is the default windless mode. After the air conditioner is turned on, it defaults to normal cooling or heating mode, at which point the windless mode is not activated. When the air conditioner receives a windless control command, it enters the default windless state, ensuring that the entire room is windless, minimizing direct drafts of cold air. The second mode is the windless front distribution mode, corresponding to a first preset distance that is relatively close to the air conditioner. In the second mode, the air conditioner delivers air within the first preset distance in windless mode, while simultaneously delivering a larger airflow to the second preset distance. The third mode is the windless bottom distribution mode, corresponding to a second preset distance that is relatively far from the air conditioner. In the third mode, the air conditioner delivers air within the second preset distance in windless mode, while simultaneously delivering a larger airflow to the first preset distance. This effectively improves cooling or heating efficiency while ensuring a windless experience for users, thereby enhancing the user experience of the air conditioner.

[0042] Furthermore, during cooling / heating, the air conditioner controls the air outlet components to switch between different air outlet states based on the distance to the target object. After the air conditioner switches to any of the first, second, and third states and runs for a specified time, it detects the ambient temperature of the space where the air conditioner is located. Based on the ambient temperature and the target temperature, it determines the amount of noise increase that the air conditioner will generate when the space reaches the target temperature. Therefore, it increases the fan speed by a reasonable decibel increase, thereby increasing the fan speed and increasing the air conditioner's cooling / heating capacity. Moreover, the noise generated during the adjustment of the fan speed will not be noticeably perceived by the user, further reducing the user's perception of "wind" and meeting various user needs.

[0043] In any of the above technical solutions, the air outlet assembly further includes: a first air guide plate disposed within the air outlet, the first air guide plate being adapted to rotate relative to the orientation of the air outlet to change the air delivery direction of the air outlet; a second air guide plate being adapted to open or close the air outlet, the second air guide plate being provided with through holes adapted to allow airflow to pass through; and a diffuser assembly being adapted to block or open the air outlet, the diffuser assembly having a diffuser structure formed thereon, the diffuser structure being adapted to allow airflow to pass through and to allow the passing airflow to diffuse and flow.

[0044] In this technical solution, the air outlet assembly includes a first air guide plate, a second air guide plate, and a diffuser assembly. The first air guide plate is located inside the air outlet and can rotate along an axis perpendicular to the air outlet, thereby changing the airflow angle to achieve "left" or "right" airflow. The second air guide plate is rotatably connected to the air conditioner's casing and is used to open or close the air outlet. Specifically, when the air conditioner is off, the second air guide plate covers the air outlet; when the air conditioner is on, the second air guide plate rotates relative to the air conditioner casing and opens the air outlet. Simultaneously, the second air guide plate has multiple through holes, which disperse the airflow into multiple intersecting small airflow streams after passing through them. When the windless mode is not activated, the diffuser assembly is retracted into the air conditioner. When the windless mode is activated, the diffuser assembly extends and blocks the air outlet. The diffuser assembly also has a diffuser structure, which disperses and diffuses the airflow passing through it, achieving "windless" and "anti-direct-blow" effects.

[0045] Specifically, the wind-dispersing structure includes multiple wind turbines, which are meshed and driven by a gear structure. Each wind turbine includes inner ribs and outer ring ribs, with a first blade and a second blade positioned between the inner and outer ring ribs. The first blade is a stationary blade, fixedly connected to the inner and outer ring ribs. The second blade is a rotating blade, rotatably connected to the inner ribs, and has a first position and a second position. In the first position, the second blade is spaced apart from the first blade. In the second position, at least a portion of the second blade overlaps with the first blade along the axial direction of the wind turbine. When the second blade rotates to the first position, the second blade and the first blade are spaced apart, resulting in a denser distribution of blades on the wind turbine, thus lowering the airflow velocity and creating a stronger "windless" effect. The second blade is in the second position, and the blades of the second blade coincide with the blades of the first blade along the axis of the wind turbine. At this time, the blades of the wind turbine are "sparsely distributed", so the airflow velocity through the wind turbine is relatively high, the "windless" effect is weak, and the air delivery capacity is strong.

[0046] Furthermore, the control device controls the air outlet assembly to operate in a first configuration, specifically including: the control device controls the air diffuser assembly to block the air outlet, controls the second fan blade to move to a first position, and controls the first air guide plate to rotate to a first angle.

[0047] The control device controls the air outlet assembly to switch from a first state to a second state, specifically including: controlling the second fan blade to move to a second position and controlling the first air guide plate to rotate from a first angle to a second angle. Specifically, when controlling the air outlet assembly to switch from the first state to the second state, the position of the air diffuser assembly remains unchanged, and the first air guide plate is controlled to rotate from the first angle to the second angle. At this time, the first air guide plate still guides the air outlet towards the air diffuser assembly, but after adjusting to the second angle, the range covered by the air outlet direction is specifically the range corresponding to a first preset distance. At the same time, the second fan blade is controlled to move to the second position to increase the air volume delivered to the first preset distance range, thereby improving the cooling or heating effect.

[0048] The control device controls the air outlet assembly to switch from a first state to a third state, specifically including: controlling the first air guide plate to rotate from a first angle to a third angle; wherein, when the first air guide plate rotates to the first angle or the second angle, the first air guide plate directs the air blown from the air outlet to the air diffuser assembly; when the first air guide plate rotates to the third angle, the first air guide plate directs the air blown from the air outlet to the second air guide plate. Specifically, when controlling the air outlet assembly to switch from the first state to the third state, the first air guide plate is controlled to rotate from the first angle to the third angle. When the first air guide plate rotates to the third angle, the first air guide plate guides the air outlet's airflow direction towards the first air guide plate, that is, the air is discharged through the through holes set in the first air guide plate. At the same time, the air diffuser assembly maintains the strongest windless effect, ensuring that people within the range corresponding to the first distance are not "directly blown" on.

[0049] According to a fourth aspect of the present invention, a computer-readable storage medium is provided on which a computer program is stored, wherein the computer program, when executed by a processor, implements the steps of the control method for an air conditioner as described above. Therefore, this computer-readable storage medium possesses all the beneficial effects of the control method for an air conditioner as described above.

[0065] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0066] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0067] The following reference Figures 1 to 11The control device 100, control method, and air conditioner 700 of an air conditioner according to some embodiments of the present invention are described.

[0068] Example 1

[0069] like Figure 1 As shown, according to an embodiment of the first aspect of the present invention, a control device 100 for an air conditioner is provided, comprising: a detection component 102, a memory 104, and a processor 106.

[0070] Specifically, the detection component 102 is adapted to detect the ambient temperature of the space where the air conditioner is located, the memory 104 stores a computer program, and the processor 106 is electrically connected to the detection component 102 and the memory 104. When the processor 106 executes the computer program, it performs the following steps: determining the noise increase of the air conditioner based at least on the ambient temperature and the target temperature; and adjusting the fan speed of the air conditioner based on the noise increase.

[0071] In this embodiment, the detection component 102 detects the ambient temperature of the space where the air conditioner is located. The processor 106, based on at least the ambient temperature and the target temperature, determines the amount of noise increase that the air conditioner will generate when the space reaches the target temperature. It then determines whether the noise increase falls within a range that is imperceptible to the user based on the relationship between the noise increase and a preset noise increase threshold. This determines the appropriate fan speed increase corresponding to a reasonable decibel increase in noise, and subsequently adjusts the air conditioner's fan speed. On one hand, this increases the air conditioning cooling capacity by increasing the fan speed, allowing for rapid room cooling, while ensuring the air conditioning frequency meets condensation limits. On the other hand, the noise generated during fan speed adjustment is not noticeably perceptible to the user, achieving windless adjustment, avoiding interference, and improving the user experience.

[0072] Specifically, the target temperature can be a preset comfort temperature or a temperature set by the user.

[0073] Example 2

[0074] According to one embodiment of the present invention, in addition to the features defined in any of the above embodiments, the processor 106 further defines that when executing the computer program, it performs the function of adjusting the fan speed of the air conditioner according to the noise increase, specifically including: comparing the magnitude relationship between the noise increase and the noise increase threshold; if the noise increase is greater than or equal to the noise increase threshold, determining the speed offset of the air conditioner according to the correspondence between the preset noise increase and the preset speed offset and the noise increase threshold; or if the noise increase is less than the noise increase threshold, determining the speed offset according to the correspondence between the preset noise increase and the preset speed offset and the noise increase; and controlling the fan speed to increase according to the speed offset.

[0075] In this embodiment, by comparing the noise increase amount with the noise increase threshold, it is determined whether the noise increase amount falls within the noise range that is difficult for the user to perceive. If the noise increase amount is greater than or equal to the noise increase threshold, it indicates that the current noise increase amount is too large and easily noticed by the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase threshold is determined. If the noise increase amount is less than the noise increase threshold, it indicates that the current noise increase amount is small. Even if the fan speed is increased according to the target temperature, the generated noise will not have a significant impact on the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase amount is determined. After determining the speed offset amount, the fan speed is controlled to increase according to the speed offset amount to achieve rapid cooling. This not only compensates for the insufficient cooling capacity caused by the limitation of fixed frequency due to condensation, but also reasonably limits the increase amount of fan speed through the noise increase threshold, ensuring that the noise generated during the adjustment of fan speed will not be obviously perceived by the user, thus improving the user experience.

[0076] Specifically, when setting the correspondence between the preset noise increase and the preset speed offset, the preset speed offset is less than or equal to the actual speed increase value required to generate the preset noise increase. For example, if the preset noise increase is 2dB and the actual fan speed increases by 30rpm, the preset speed offset is set to 25rpm, thereby avoiding errors in the calculation of the noise increase.

[0077] Example 3

[0078] like Figure 2 As shown, according to an embodiment of the present invention, a control device 100 for an air conditioner is provided, the device comprising: a detection component 102, a memory 104, a processor 106, and a timer 108.

[0079] Specifically, the timer 108 is electrically connected to the processor 106 and is used to compare the running time with a preset time, and determine a noise growth threshold based on the comparison, even when the processor 106 is executing a computer program, even if the air conditioner is running for a certain period of time. It also compares the noise growth amount with the noise growth threshold. If the noise growth amount is detected to be greater than or equal to the noise growth threshold, it determines the air conditioner's speed offset based on the correspondence between the preset noise growth amount and the preset speed offset, and the noise growth threshold. Alternatively, if the noise growth amount is detected to be less than the noise growth threshold, it determines the speed offset based on the correspondence between the preset noise growth amount and the preset speed offset, and the noise growth amount. Finally, it controls the fan speed to increase according to the speed offset.

[0080] In this embodiment, by comparing the noise increase amount with the noise increase threshold, it is determined whether the noise increase amount falls within the noise range that is difficult for the user to perceive. If the noise increase amount is greater than or equal to the noise increase threshold, it indicates that the current noise increase amount is too large and easily noticed by the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase threshold is determined. If the noise increase amount is less than the noise increase threshold, it indicates that the current noise increase amount is small. Even if the fan speed is increased according to the target temperature, the generated noise will not have a significant impact on the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase amount is determined. After determining the speed offset amount, the fan speed is controlled to increase according to the speed offset amount to achieve rapid cooling. This not only compensates for the insufficient cooling capacity caused by the limitation of fixed frequency due to condensation, but also reasonably limits the increase amount of fan speed through the noise increase threshold, ensuring that the noise generated during the adjustment of fan speed will not be obviously perceived by the user, thus improving the user experience.

[0081] Furthermore, since hearing has a certain degree of adaptability, even very small noises can be detected in a low-noise environment over a long period of time. Conversely, in a noisy environment, even a significant increase in noise will not be easily perceived. Therefore, by recording the running time of the air conditioner using timer 108, the noise increase threshold is determined based on the relationship between the running time and the preset duration. If the running time is greater than the preset duration, it indicates that the user has adapted to the noise generated by the air conditioner. In this case, the noise increase threshold can be appropriately increased to maximize the range of speed deviation that can be increased, thereby achieving better rapid cooling. The noise increase threshold and the preset duration can be reasonably set according to the noise level generated by the air conditioner and the user's needs.

[0082] Specifically, the preset duration is between 1 min and 10 min. If the runtime is longer than the preset duration, the noise growth threshold is between 0 dB and 3 dB. If the runtime is less than or equal to the preset duration, the noise growth threshold is between 0 dB and 1.5 dB.

[0083] Example 4

[0084] According to one embodiment of the present invention, in addition to the features defined in the above embodiments, it is further defined that: when the processor 106 executes the computer program, it performs the function of determining the noise increase of the air conditioner based on the ambient temperature and the target temperature, specifically including: determining the temperature difference between the ambient temperature and the target temperature; and determining the noise increase corresponding to the temperature difference based on the correspondence between the preset temperature difference and the preset noise increase.

[0085] In this embodiment, the temperature difference between the ambient temperature and the target temperature is calculated, and then the noise increase corresponding to the temperature difference is determined according to the correspondence between the preset temperature difference and the preset noise increase amount. That is, the noise generated by the air conditioner when adjusting the temperature according to the temperature difference is compared with the noise generated by the current operation of the air conditioner, so as to adjust the fan speed without causing obvious user perception.

[0086] Furthermore, even when the correspondence between the preset temperature difference and the preset noise increase is uncertain, the current fan speed of the air conditioner can be obtained, the noise value of the air conditioner can be determined based on the current fan speed, the target fan speed can be determined based on the preset temperature difference, and the noise threshold corresponding to the target fan speed can be determined. Based on the noise value and the noise threshold, the noise increase can be calculated.

[0087] Example 5

[0088] According to one embodiment of the present invention, in addition to the features defined in the above embodiments, the processor 106 further executes the following when executing the computer program: determining whether the temperature difference is less than a preset stop temperature; and stopping the adjustment of the fan speed when the temperature difference is determined to be less than the preset stop temperature.

[0089] In this technical solution, if the temperature difference is less than the preset stop temperature, it means that the air conditioner has almost finished adjusting the indoor temperature. At this time, the fan speed is stopped and the air conditioner operates at the normal speed to reduce the energy consumption of the air conditioner and meet the energy-saving requirements.

[0090] Example 6

[0091] like Figure 3 As shown, according to an embodiment of the second aspect of the present invention, a control method for an air conditioner is provided, the method comprising:

[0092] Step 302: Detect the ambient temperature of the space where the air conditioner is located;

[0093] Step 304: Determine the noise increase of the air conditioner based at least on the ambient temperature and the target temperature;

[0094] Step 306: Adjust the fan speed of the air conditioner according to the noise increase.

[0095] In this embodiment, the ambient temperature of the space where the air conditioner is located can be detected. Based on at least the ambient temperature and the target temperature, the amount of noise increase the air conditioner will generate when the space reaches the target temperature can be determined. The noise increase is then assessed to determine whether it falls within a range that is imperceptible to the user, thereby determining the appropriate fan speed increase corresponding to a reasonable decibel increase in noise. This allows for the adjustment of the air conditioner's fan speed. On one hand, while ensuring the air conditioning frequency meets condensation limits, increasing the fan speed can increase the cooling capacity of the air conditioner, enabling rapid room cooling. On the other hand, the noise generated during fan speed adjustment is not noticeable to the user, achieving a windless adjustment that avoids user interference and improves the user experience.

[0096] Example 7

[0097] like Figure 4 As shown, according to an embodiment of the present invention, a control method for an air conditioner is proposed, the method comprising:

[0098] Step 402: Detect the ambient temperature of the space where the air conditioner is located and time the running time of the air conditioner;

[0099] Step 404: Determine the noise increase of the air conditioner based on the ambient temperature and the target temperature;

[0100] Step 406: Compare the running time with the preset duration;

[0101] Step 408: Determine the noise growth threshold based on the magnitude relationship;

[0102] Step 410: Is the noise increase greater than or equal to the noise increase threshold? If yes, proceed to step 412; otherwise, proceed to step 414.

[0103] Step 412: Determine the air conditioner's speed offset based on the correspondence between the preset noise increase and the preset speed offset, and the noise increase threshold.

[0104] Step 414: Determine the speed offset based on the correspondence between the preset noise increase and the preset speed offset, and the noise increase.

[0105] Step 416: Control the fan speed to increase according to the speed offset.

[0106] In this embodiment, by comparing the noise increase amount with the noise increase threshold, it is determined whether the noise increase amount falls within the noise range that is difficult for the user to perceive. If the noise increase amount is greater than or equal to the noise increase threshold, it indicates that the current noise increase amount is too large and easily noticed by the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase threshold is determined. If the noise increase amount is less than the noise increase threshold, it indicates that the current noise increase amount is small. Even if the fan speed is increased according to the target temperature, the generated noise will not have a significant impact on the user. At this time, based on the correspondence between the preset noise increase amount and the preset speed offset amount, the speed offset amount corresponding to the noise increase amount is determined. After determining the speed offset amount, the fan speed is controlled to increase according to the speed offset amount to achieve rapid cooling. This not only compensates for the insufficient cooling capacity caused by the limitation of fixed frequency due to condensation, but also reasonably limits the increase amount of fan speed through the noise increase threshold, ensuring that the noise generated during the adjustment of fan speed will not be obviously perceived by the user, thus improving the user experience.

[0107] Furthermore, since hearing has a certain degree of adaptability, even very small noises can be detected in a relatively quiet environment over a long period of time. Conversely, in a noisier environment, even a significant increase in noise may not be easily perceived. Therefore, by recording the running time of the air conditioner using a timer, the noise increase threshold can be determined based on the relationship between the running time and the preset duration. If the running time is longer than the preset duration, it indicates that the user has become accustomed to the noise generated by the air conditioner. In this case, the noise increase threshold can be appropriately increased to maximize the range of possible speed deviation and achieve better rapid cooling. The noise increase threshold and the preset duration can be reasonably set according to the noise level generated by the air conditioner and the user's needs.

[0108] Example 8

[0109] like Figure 5 As shown, according to an embodiment of the present invention, a control method for an air conditioner is proposed, the method comprising:

[0110] Step 502: Detect the ambient temperature of the space where the air conditioner is located;

[0111] Step 504: Determine the temperature difference between the ambient temperature and the target temperature;

[0112] Step 506: Is the temperature difference greater than or equal to the preset stop temperature? If yes, proceed to step 508; otherwise, proceed to step 512.

[0113] Step 508: Determine the noise increase corresponding to the temperature difference based on the correspondence between the preset temperature difference and the preset noise increase.

[0114] Step 510: Adjust the fan speed of the air conditioner according to the noise increase, and proceed to step 502;

[0115] Step 512: Stop adjusting the fan speed.

[0116] In this embodiment, the temperature difference between the ambient temperature and the target temperature is calculated. If the temperature difference is less than the preset stop temperature, it indicates that the air conditioner has nearly completed adjusting the indoor temperature. At this point, the fan speed is stopped, and the air conditioner operates at its normal speed to reduce resource consumption and meet energy-saving requirements. If the temperature difference is greater than or equal to the preset stop temperature, the noise increase corresponding to the temperature difference is determined based on the correspondence between the preset temperature difference and the preset noise increase. That is, the noise generated by the air conditioner when adjusting the temperature according to the temperature difference is compared to the noise generated by the air conditioner during current operation. This allows the fan speed to be adjusted without causing noticeable noise to the user.

[0117] Example 9

[0118] like Figure 6 As shown in a specific embodiment of the present invention, a control method for an air conditioner is proposed. When the user turns on the air conditioner, it is determined that the indoor air conditioner is operating normally. If normal, the indoor room temperature Tw, the indoor unit running time S, and the indoor unit operating speed Pn are detected. Within a first preset time Sy, the indoor unit operates at its maximum fan speed or the user-set fan speed. If the running time exceeds the first preset time Sy, the difference between the room temperature and the comfortable temperature or the set temperature, and the noise Zn corresponding to the current indoor unit speed Pn are calculated. Based on Zn and a reasonable increase in noise level, a method to increase the speed Pn+1 is calculated. For example, an increase of 1 dB corresponds to one Pn+1, an increase of x dB corresponds to a new Pn+1, and the magnitude of the speed increase depends on the amount of noise increase, and so on, as long as it is within a reasonable noise increase range.

[0119] Furthermore, before adjusting the speed, the relationship between the running time S and the preset time is compared. If the running time is less than or equal to the first preset time, the reasonable range for noise increase is W1. In this case, the indoor unit speed is increased accordingly based on the difference between Tw and the comfortable temperature or set temperature. If the running time S is greater than the first preset time, the reasonable range for noise increase is W2. In this case, the indoor unit speed is increased accordingly based on the difference between Tw and the comfortable temperature or set temperature. Wherein, the first preset time Sy: 1min-10min; the noise increase range W1: 0≤W1≤1.5dB; the noise increase range W2: 0≤W2≤3dB. Taking the noise increase range W2 as an example, if the difference is within 0-1.5℃, the indoor unit speed is operated according to the speed corresponding to an increase of 0-1.5dB in Pn; if the difference is above 3℃, the indoor unit speed is operated according to the speed corresponding to an increase of 3dB in Pn.

[0120] In this embodiment, in cooling mode, while meeting the condensation limit, the indoor unit speed is adjusted to quickly cool the room and improve the user experience without causing significant noise increase to be noticeable to the user.

[0121] Example 10

[0122] According to an embodiment of a third aspect of the present invention, an air conditioner is provided, comprising a control device for the air conditioner proposed in the second aspect embodiment above, the control device being adapted to perform the following steps: detecting the rotational speed of the air conditioner and the ambient temperature of the space where the air conditioner is located; determining the noise increase of the air conditioner based on the ambient temperature, a preset temperature, and the rotational speed.

[0123] The air conditioner provided in this embodiment can detect the ambient temperature of the space where the air conditioner is located. Based on at least the ambient temperature and the target temperature, it determines the amount of noise increase the air conditioner will generate when the space reaches the target temperature. It then judges whether the noise increase falls within a range that is imperceptible to the user, thereby determining the appropriate fan speed increase corresponding to a reasonable decibel increase in noise, and subsequently adjusting the air conditioner's fan speed. On the one hand, while ensuring the air conditioning frequency meets condensation limits, increasing the cooling capacity by increasing the fan speed allows for rapid room cooling. On the other hand, the noise generated during fan speed adjustment is not noticeable to the user, achieving windless adjustment, avoiding interference and improving the user experience. Specifically, the air conditioner also includes a load and a display. The load includes a fan and / or compressor, and the display is used to show fault information, etc.

[0124] Example 11

[0125] like Figure 7 and Figure 8 As shown, according to an embodiment of the present invention, including the features defined in the above embodiments, and further, the air conditioner 700 includes: an air outlet 702; an air outlet assembly 800 electrically connected to a control device, the air outlet assembly 800 being configured to adjust the air outlet 702, the air outlet assembly 800 having multiple forms; the control device is also adapted to control the air outlet assembly 800 to switch forms according to the position information of the target object.

[0126] In this embodiment, air that has exchanged heat with the indoor heat exchanger is blown out through the air outlet to achieve cooling or heating. The air outlet assembly can adjust the air outlet angle. The air conditioner's control device can detect the location information of a target object, which can be a human body or a preset object, such as furniture where a person might linger, like a bed, desk, or sofa. By controlling the air outlet assembly 800 to switch modes based on the target object's location information, the direction of the target object can be kept windless, thus ensuring that the airflow does not blow directly onto the human body and improving the comfort of the air conditioner 700. In areas outside the target object's location, the airflow can be increased through methods such as direct airflow, thereby improving cooling / heating efficiency while ensuring the human body's need for a windless environment. Meanwhile, based on the absence of wind, the control device determines the amount of noise increase that the air conditioner 700 will generate when the space reaches the target temperature, based on the ambient temperature and the target temperature. It then increases the fan speed by a reasonable decibel increase, thereby increasing the cooling / heating capacity of the air conditioner. Furthermore, the noise generated during the adjustment of the fan speed will not be noticeably perceived by the user. While improving cooling / heating efficiency, it avoids the user's perception of "wind" and meets various user needs.

[0127] The definition of "no wind" is as follows: when the average wind speed is less than 0.1 m / s within a distance of 2.5 to 3 meters from the air conditioner's air outlet, or when the DR value is between 5 and 20 at a distance of 2.5 meters or less from the air outlet, it is considered that there is "no wind".

[0128] Specifically, distance values ​​can be detected using an infrared distance detection device, or an image of the area in front of the air conditioner can be captured. The location of the target object can then be determined using an image recognition device, and the distance value can be further determined. Alternatively, the distance to the target object can be detected using a radar position detection device.

[0129] Example 12

[0130] like Figure 9 , Figure 10 and Figure 11 As shown, according to one embodiment of the present invention, including the features defined in the above embodiments, and further, the air outlet assembly 800 of the air conditioner 700 has multiple forms.

[0131] Among them, such as Figure 9 As shown, among the multiple modes is the first mode, in which the control device controls the air outlet assembly 800 to operate in the first mode according to the control command.

[0132] like Figure 10 and Figure 11As shown, the multiple forms also include a second form and a third form. The control device controls the air outlet component 800 to switch forms according to the distance value, specifically including: obtaining a first preset distance range and a second preset distance range; determining that the distance value is within the first preset distance range, controlling the air outlet component 800 to switch from the first form to the second form; determining that the distance value is within the second preset distance range, controlling the air outlet component 800 to switch from the first form to the third form.

[0133] In this embodiment, the first state is specifically the default windless state. After the air conditioner 700 is turned on, it defaults to normal cooling or normal heating mode, at which time the windless mode is not activated. When the air conditioner 700 receives the corresponding control command, specifically the windless control command, the air conditioner 700 enters the default windless state. At this time, the entire room is in a windless state, ensuring that people are not directly "blown" by the cold air from the air conditioner 700 to the greatest extent possible.

[0134] in, Figure 9 A schematic diagram of the air outlet assembly 800 in its first state. Figure 10 This diagram shows the air outlet assembly 800 in its second configuration. Figure 11 A schematic diagram of the air outlet assembly 800 in its third state is shown.

[0135] The second mode is a windless front distribution state, with the corresponding first preset distance being a distance range relatively close to the air conditioner 700. In the second mode, the air conditioner 700 delivers air to the range within the first preset distance in a windless mode, while simultaneously delivering air to the range within the second preset distance with a larger air volume.

[0136] The third mode is a windless, lower-side distribution state, with the corresponding second preset distance being a distance range relatively far from the air conditioner 700. In the third mode, the air conditioner 700 delivers air to the range within the second preset distance in a windless mode, while simultaneously delivering air to the range within the first preset distance with a larger air volume.

[0137] By controlling the air outlet component 800 to switch different air outlet states according to the distance to the target object, the cooling or heating efficiency can be effectively improved while ensuring that the human body does not feel "wind", thereby enhancing the user experience of the air conditioner 700.

[0138] Furthermore, during cooling / heating, the air conditioner 700 controls the air outlet assembly 800 to switch between different air outlet states based on the distance to the target object. After the air conditioner 700 switches to any of the first, second, and third states and runs for a specified time, it detects the ambient temperature of the space where the air conditioner 700 is located. Based on the ambient temperature and the target temperature, it determines the amount of noise increase that the air conditioner 700 will generate when the space reaches the target temperature. Therefore, it increases the fan speed by a reasonable decibel increase, thereby increasing the fan speed and increasing the air conditioning's cooling / heating capacity. Moreover, the noise generated during the adjustment of the fan speed will not be noticeably perceived by the user, further reducing the user's perception of "wind" and meeting various user needs.

[0139] Example 13

[0140] like Figure 9 , Figure 10 and Figure 11 As shown, according to an embodiment of the present invention, including the features defined in the above embodiments, and further comprising: a first air guide plate 802 disposed within an air outlet 702, the first air guide plate 802 being adapted to swing relative to the orientation of the air outlet 702 to change the air delivery angle of the air outlet 702; a second air guide plate 804 configured to open or close the air outlet 702, the second air guide plate 804 being provided with a through hole suitable for airflow to pass through; and a diffuser assembly 806 adapted to block or open the air outlet 702, the diffuser assembly 806 being formed with a diffuser structure suitable for airflow to pass through and suitable for causing the passing airflow to diffuse and flow.

[0141] In this embodiment, the air outlet assembly 800 includes a first air guide plate 802, a second air guide plate 804, and a diffuser assembly 806. The first air guide plate 802 is disposed within the air outlet 702 and can rotate along an axis perpendicular to the air outlet 702, thereby changing the air delivery angle of the air outlet 702 to achieve "left" or "right" air delivery. The second air guide plate 804 is used to open or close the air outlet 702. Specifically, when the air conditioner is off, the second air guide plate 804 covers the air outlet; when the air conditioner is on, the second air guide plate 804 rotates relative to the air conditioner housing and opens the air outlet 702. Simultaneously, the second air guide plate 804 has multiple through holes, which disperse the airflow into multiple intersecting small airflows after passing through the through holes. When the windless mode is not activated, the diffuser assembly 806 is housed within the air conditioner 700. When the windless mode is activated, the air diffuser 806 extends and abuts against one end of the second air guide plate 804, blocking the air outlet 702. The air diffuser 806 is also equipped with an air diffusion structure, which can disperse and diffuse the airflow passing through the air diffuser 806, thereby achieving "windless" and "anti-direct blowing".

[0142] Furthermore, the air dispersion structure also includes multiple impellers 900, which are driven by a gear mechanism and rotate under the drive of a motor to disperse the passing airflow. Each impeller 900 includes an inner rib 902 and an outer ring rib 904, with a first blade 906 and a second blade 908 positioned between them. The first blade 906 is a stationary blade, fixedly connected to the outer ring rib 904 and the inner rib 902. The second blade 908 is a moving blade, capable of rotating around the inner rib 902 and switching between a first position and a second position. Specifically, when the second blade 908 rotates to the first position, the second blade 908 and the first blade 906 are arranged alternately, resulting in a "dense" blade distribution on the impeller 900. Therefore, the airflow velocity through the impeller 900 is low, creating a stronger "windless" effect. When the second blade 908 rotates to the second position, at least part of the second blade 908 overlaps with the first blade 906. At this time, the blade distribution of the impeller 900 is "sparse", so the airflow velocity through the impeller 900 is relatively high, the "windless" effect is weak, and the air delivery capacity is strong.

[0143] Furthermore, the control device controls the air outlet assembly 800 to operate in a first configuration according to control commands. Specifically, this includes: the control device controlling the air diffuser assembly 806 to block the air outlet 702, controlling the second fan blade 908 to move to a first position, and controlling the first guide vane 802 to rotate to a first angle. In the first configuration, the air outlet assembly 800 rotates to abut against the air diffuser assembly 806, and the first guide vane 802 guides the air blown from the air outlet 702 to the air diffuser assembly 806, with the second fan blade 908 positioned in the first position.

[0144] The control device controls the air outlet assembly 800 to switch from a first state to a second state, specifically including: controlling the second fan blade 908 to move to a second position, and controlling the first air guide plate 802 to rotate from a first angle to a second angle. In the second state, the air outlet assembly 800 has the air diffuser assembly 806 blocking the air outlet 702, the second air guide plate 804 rotating to abut against the air diffuser assembly 806, and the first air guide plate 802 directing the air blown from the air outlet 702 towards the air diffuser assembly 806, with the second fan blade 908 in the second position.

[0145] The control device controls the air outlet assembly 800 to switch from a first state to a third state, specifically including: controlling the first air guide plate 802 to rotate from a first angle to a third angle; wherein, when the first air guide plate 802 rotates to the first angle or the second angle, the first air guide plate 802 guides the air blown out of the air outlet 702 to the air diffuser assembly 806; when the first air guide plate 802 rotates to the third angle, the first air guide plate 802 guides the air blown out of the air outlet 702 to the second air guide plate 804. In the third state, the air outlet assembly 800 is in the air diffuser assembly 806 blocking the air outlet 702, the second air guide plate 804 rotates to abut against the air diffuser assembly 806, the first air guide plate 802 guides the air blown out of the air outlet 702 to the second air guide plate 804, and the second fan blade 908 is in the first position.

[0146] In addition, the second air guide plate 804 and the air diffuser assembly 806 are combined to define an angled cavity located outside the air conditioner outlet 702 and connected to the air conditioner outlet 702. The cavity has side openings at both ends along the length of the splicing line of the second air guide plate 804 and the air diffuser assembly 806. The side openings are connected to the cavity, thereby realizing air supply from both sides.
