These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0019] The technical solutions of the embodiments 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, and 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.

[0020] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0022] This invention relates to the field of air conditioning technology. As a core tool for regulating temperature, the performance of air conditioning directly affects the user's comfort experience. During the cooling operation of air conditioning, there is a dynamic balance contradiction between the user's needs for rapid cooling, comfort, and energy saving.

[0023] Specifically, when the outdoor temperature is high or the indoor temperature rises sharply, users want the air conditioner to release maximum cooling energy in the shortest possible time to quickly lower the indoor temperature. Traditional air conditioners may maintain high airflow for extended periods at high temperatures, leading to increased energy consumption or excessively low airflow temperatures that cause discomfort. Furthermore, if the airflow is not adjusted promptly after the temperature drops, it may result in energy waste or fluctuations in indoor temperature. Additionally, some users are accustomed to manually setting the fan speed, but manual settings may not meet the need for rapid cooling at high temperatures, requiring users to frequently adjust the fan speed.

[0024] In existing technologies, air conditioning indoor fan control technology typically controls the operating parameters of the indoor fan, such as its speed, based on fixed conditions such as a fixed air volume or a single temperature threshold. For example, it controls the operating parameters of the indoor fan, such as its speed, based on a fixed air volume of three levels (high, medium, and low), or by fixing the high fan speed when the room temperature is above 30°C.

[0025] However, existing technology cannot dynamically adjust the air volume according to temperature changes, resulting in insufficient cooling efficiency at high temperatures or excessive energy consumption at low temperatures, which seriously affects the cooling effect of the air conditioner and reduces the user experience.

[0026] Some air conditioners support operating in "Rampage Mode," in which the air conditioner can increase the compressor frequency and cooling output in a short period of time, achieving a faster cooling effect to lower the room temperature.

[0027] Specifically, in the Frenzy Mode, the compressor operates at a frequency greater than a preset frequency, and / or the fan (inner or outer) operates at a speed greater than a preset speed. The preset frequency is the maximum value of the compressor operating frequency in other modes, and the preset speed is the maximum speed of the fan in other modes. Other modes are modes other than Frenzy Mode.

[0028] Other modes can be modes that meet noise requirements. For example, other modes may include gentle breeze mode, normal cooling / heating mode, and the highest fan speed setting. When the air conditioner is in these modes, the noise generated by the air conditioner needs to be lower than the preset noise level. For example, if the preset noise level of the indoor unit is 42 decibels and the preset noise level of the outdoor unit is 52 decibels, when the air conditioner is in these modes, the compressor and indoor / outdoor fans will generate noise, but the noise levels of the indoor and outdoor units will still be within the preset noise levels of the indoor and outdoor units, respectively.

[0029] The preset noise levels of the indoor and outdoor units refer to the noise values ​​of the indoor and outdoor units as indicated on the nameplate of the air conditioner, based on national standards.

[0030] In some embodiments, when the operating frequency of the air conditioner's compressor is greater than a preset frequency, it indicates that the present invention targets the air conditioner's "overpowered" mode. Specifically, the preset frequency is not the physical limit frequency that the compressor's hardware structure can withstand, but rather the maximum frequency among the normal frequencies set by the air conditioner in other modes to balance daily energy efficiency, equipment wear and tear, and operating noise. This normal frequency is based on scenarios of stable operation rather than extreme performance.

[0031] The core characteristic of the "Rampage Mode" is that the compressor operates at a frequency higher than the preset frequency. This is because the primary requirement of Rampage Mode is to rapidly reduce indoor temperature differences, thus exceeding the frequency limitations of normal mode. The compressor operates at a higher frequency to maximize cooling / heating capacity. In other words, Rampage Mode overcomes noise limitations to achieve maximum cooling or heating effects. This ensures that while the compressor's operating frequency exceeds the conventional upper limit, it remains below the compressor's hardware limits, achieving a balance between high-frequency efficiency and operational safety, precisely matching the usage scenarios of Rampage Mode.

[0032] In operating modes other than the scorching mode, the highest operating frequency of the compressor at maximum load is n1. In scorching mode, the compressor operating frequency is n2. Under the same operating conditions, n2 > n1, where n1 is less than the upper limit of the compressor nameplate frequency, and n2 is less than or equal to the upper limit of the compressor nameplate frequency. For example, in operating modes other than the scorching mode, taking a certain model of air conditioner as an example, in cooling mode, n1 is (80-90) Hz, in heating mode, n1 is (100-110) Hz, in scorching mode, in cooling mode, n2 is (91-140) Hz, and in heating mode, n2 is (111-140) Hz.

[0033] Taking a 1.5 horsepower air conditioner as an example, in all operating modes except for the "Raging Mode", the compressor operates at a maximum frequency of 108 Hz when at maximum load, reaching 77% of the upper limit of the compressor nameplate frequency. In "Raging Mode", the compressor is allowed to operate at a frequency exceeding 108 Hz, but less than or equal to 140 Hz. That is, in "Raging Mode", the compressor's maximum operating frequency can reach 100% of the upper limit of the compressor nameplate frequency.

[0034] The "Rampage Mode" can overcome the limitations of other modes, allowing at least one of the following—the compressor's operating frequency, the internal fan speed, and the external fan speed—to exceed preset values, or all of them can exceed preset values ​​simultaneously. However, compared to other modes, it also approaches the hardware limits of the compressor, internal fan, and external fan. Prolonged operation may cause the temperature of electrical components and control systems to exceed their limits. Therefore, within the design margin, Rampage Mode is allowed to run for 5-60 minutes before exiting. The duration of Rampage Mode can be set by the user or left as a default value.

[0035] When an air conditioner is switched to its "extreme" mode, if the indoor fan speed cannot adjust according to temperature changes, it can lead to insufficient cooling efficiency at high temperatures or excessive energy consumption at low temperatures. Specifically, when the indoor fan speed cannot adjust according to temperature changes, it can result in insufficient cooling efficiency at high temperatures or excessive energy consumption at low temperatures, severely reducing the air conditioner's energy efficiency and user experience.

[0036] Based on this, the present invention provides a strategy for dynamically controlling the speed of the indoor fan based on the indoor ambient temperature. By establishing a functional relationship between the fan speed and the room temperature, the cooling performance of the air conditioner and the user comfort are dynamically balanced based on the adjustment of the indoor fan speed, thereby reducing the energy consumption of the air conditioner and improving the user experience.

[0037] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0038] Figure 1 This is a flowchart illustrating an embodiment of the air conditioner indoor fan control method provided by the present invention, as shown below. Figure 1 The method shown can be used to control the speed of the indoor fan of an air conditioner.

[0039] In one embodiment, such as Figure 1 The method shown can be executed by the control device or controller of the indoor fan of the air conditioner. For example, the indoor fan of the air conditioner can be equipped with an indoor fan controller, which can be used to control the speed of the indoor fan. The indoor fan controller can be an independent controller or it can be integrated into the main controller of the air conditioner.

[0040] Specifically, such as Figure 1 The control methods for the indoor fan of the air conditioner shown include:

[0041] S101: Obtain the indoor ambient temperature when the air conditioner is in extreme mode.

[0042] In one embodiment, the indoor fan of the air conditioner may also be equipped with a temperature sensor, which sends the detected indoor ambient temperature to the air conditioner's controller. In another embodiment, the temperature sensor may detect the indoor ambient temperature and send it to the controller according to a preset period or frequency; alternatively, the controller may send a data acquisition command to the temperature sensor when needed, causing the temperature sensor to acquire the indoor ambient temperature according to the acquisition command and then send it to the controller.

[0043] In one embodiment, the controller acquires the latest indoor ambient temperature collected by the current temperature sensor after the air conditioner enters the rage mode.

[0044] The air conditioner can enter "violent mode" by the user via remote control, application, or other means, or it can be preset before the air conditioner is turned on, and the air conditioner will directly enter violent mode after being turned on.

[0045] S102: Determine the first target rotational speed corresponding to the indoor ambient temperature obtained in S101.

[0046] In one embodiment, in S102, the controller of the indoor fan determines a first target rotational speed corresponding to the indoor ambient temperature based on a preset nonlinear function relationship. Specifically, within a preset temperature range, the indoor ambient temperature is positively correlated with the first target rotational speed in the preset nonlinear function.

[0047] Specifically, the preset nonlinear function can be pre-defined or calculated by the indoor fan controller. The preset function can establish a nonlinear relationship between fan speed and room temperature based on the room temperature change curve, with higher room temperature resulting in faster speed. For example, in the preset function, when the room temperature rises from 30°C to 35°C, the indoor fan speed correspondingly increases from 50% to 80%; when the room temperature drops from 35°C to 30°C, the indoor fan speed gradually decreases to 50%, and so on.

[0048] This embodiment provides a nonlinear function relationship for dynamically adjusting the fan speed. Through a gradient airflow control strategy, it can effectively match the room temperature change curve, thereby achieving a gradient control strategy where the airflow increases as the room temperature rises. Specifically, the process is based on thermodynamic principles. In high-temperature environments, increased airflow speed improves heat exchange efficiency, thus accelerating cooling. By establishing a nonlinear function relationship, the fan speed can be matched with the room temperature change curve, ultimately achieving efficient release of extreme cooling energy in the intensive cooling mode.

[0049] In another embodiment of the present invention, in S102, the controller of the indoor fan can further determine the first target speed of the indoor fan based on the temperature range of the indoor ambient temperature obtained in S101, and / or the target speed range set for the indoor fan. The target speed range set for the indoor fan can be set by the air conditioner user through the air conditioner's interface or application.

[0050] For example, Figure 2 This is a schematic diagram of determining the first target rotational speed of the internal fan provided by the present invention, specifically, as shown in the figure. Figure 2 As shown, in this embodiment, the controller of the internal fan can determine the first target speed of the internal fan in the following manner:

[0051] When the indoor ambient temperature falls within the highest temperature range, the maximum speed of the indoor fan is determined as the first target speed. Specifically, when the indoor environment is in the highest temperature range, which corresponds to the set uncomfortable temperature range, the indoor fan speed is controlled at its maximum speed to achieve cooling more quickly, thus using the maximum speed of the indoor fan as the first target speed.

[0052] When the indoor ambient temperature falls within the medium-high temperature range, the first target speed of the indoor fan is determined based on a speed range one level higher than the first target speed range. However, for indoor environments that are not in the highest temperature range but still fall within the relatively hot medium-high temperature range, more effective cooling is still required. Therefore, a speed level can be added to the user-set first target speed range, thus determining the target speed based on a speed range one level higher than the first target speed range.

[0053] For example, the highest temperature range is greater than 33℃, the medium-high temperature range is 33℃-29℃, and the comfortable temperature range is less than 29℃. If the user sets the first target speed range to the medium-high temperature range, and the room temperature drops from 35℃ (highest temperature range) to 30℃ (medium-high temperature range) to 28℃ (comfortable temperature range), the fan speed will sequentially change from 80% (highest speed) → 60% (medium-high temperature range + 1) → 50% (medium-high temperature range).

[0054] When the indoor ambient temperature falls within the comfortable temperature range, the first target speed of the indoor fan is determined based on the first target speed range. Specifically, when the indoor environment enters the user-set comfortable temperature range, there is no need for rapid cooling. From an energy consumption perspective, the indoor fan speed can be reduced, but this must be combined with the user-set target speed range; the speed within the target speed range can be used as the first target speed.

[0055] As can be seen, this embodiment can achieve a dynamic balance between performance priority and user habits through phased temperature threshold management. Especially at high temperatures, rapid cooling is required, so the user setting is directly overridden and the highest setting is directly controlled. At medium temperatures, the setting is increased by one level based on the user setting to ensure cooling efficiency. At medium temperatures, energy efficiency and comfort need to be balanced, and at low temperatures, the user setting needs to be respected. Furthermore, during changes in indoor temperature, the fan speed is dynamically switched to avoid the energy waste or decreased comfort issues of a fixed fan speed mode.

[0056] In one embodiment, the methods for determining the first target speed of the indoor fan based on the relationship between the indoor ambient temperature and a preset function, and for determining the first target speed of the indoor fan based on the temperature range of the indoor ambient temperature and / or the first target speed range set for the indoor fan, can be implemented selectively or simultaneously. For example, when both methods are implemented simultaneously, the controller of the indoor unit can determine the first target speed of the indoor fan based on both methods. When the two methods are consistent or the difference between them is close to a preset value, either speed can be used as the first target speed. When the two methods are inconsistent or the difference between them is greater than a preset value, the speed calculated by the method with higher priority can be used as the first target speed. The priority can be set by the user or preset by the controller of the indoor fan.

[0057] S103: Control the indoor fan of the air conditioner to run at the first target speed determined in S102.

[0058] In one embodiment, the controller of the internal fan controls the internal fan to operate at a first target speed.

[0059] In one embodiment, the controller of the indoor fan, in response to the air conditioner exiting the extreme mode, can control the indoor fan to rotate at a speed set by the user, or control the indoor fan to rotate at a preset speed, etc. Specifically, the air conditioner can exit the extreme mode after the indoor ambient temperature meets a certain temperature condition, or after a period of time, or it can exit the extreme mode at the user's instruction.

[0060] Understandably, before exiting the extreme mode, the indoor fan controller controls the air conditioner's indoor fan to operate at a first target speed. In one embodiment, the indoor fan controller can also continue to acquire changes in the indoor ambient temperature while controlling the air conditioner's indoor fan to rotate at the first target speed, and determine the first target speed based on the method in S102, thereby achieving real-time updates to the first target speed, ensuring the effectiveness and real-time nature of the first target speed, and thus ensuring the air conditioner's continuous and stable operation throughout the entire extreme mode process.

[0061] In summary, the air conditioner indoor fan control method provided by this invention acquires the indoor ambient temperature and determines a first target speed corresponding to the indoor ambient temperature when the air conditioner enters the sprint mode. This allows the indoor fan to be controlled to run at the first target speed. By establishing a functional relationship between the fan speed and the room temperature, the cooling performance of the air conditioner and user comfort are dynamically balanced based on the adjustment of the indoor fan speed, thereby reducing the energy consumption of the air conditioner and improving the user experience.

[0062] Specifically, based on thermodynamic principles, increased airflow speed in high-temperature environments improves heat exchange efficiency, thereby accelerating cooling. Therefore, the air conditioner fan control method provided in this embodiment matches the fan speed to the room temperature change curve, avoiding the lag inherent in fixed airflow modes. For example, in high-temperature scenarios, the system can quickly respond to rising room temperature and increase airflow, significantly shortening cooling time; conversely, as room temperature drops, it gradually reduces airflow to minimize energy consumption. Simultaneously, this strategy eliminates the abrupt changes in airflow caused by traditional fixed fan speeds, preventing users from experiencing discomfort from airflow changes. Ultimately, this technology achieves a dynamic balance between cooling performance and energy efficiency, while simultaneously improving user comfort.

[0063] Furthermore, existing technologies directly switch to the highest fan speed in high-temperature scenarios using a "tyrannical mode," without considering the coordination between the user's original fan speed settings and performance requirements, leading to a conflict between comfort and energy efficiency. This invention provides a system that, upon detecting high temperature or the activation of tyrannical mode, compares the room temperature with a comfort threshold and dynamically overrides the user's original fan speed settings. For example, it directly controls the highest setting at high temperatures, and increases the setting by one level at medium to high temperatures. This resolves the conflict between performance priorities and user habits through scenario analysis. Specifically, in high-temperature environments, the system prioritizes rapid cooling by directly switching to the highest fan speed; while in medium-temperature environments, it moderately increases the fan speed based on the user's original settings to avoid excessive energy consumption. Through dynamic override logic, the system can quickly respond to user needs in extreme scenarios while respecting user preferences in normal scenarios, reducing unnecessary energy consumption. Furthermore, this strategy achieves a smooth transition between performance and comfort by adjusting the fan speed in stages. This allows for gradual optimization of airflow based on temperature changes, avoiding user discomfort caused by abrupt switching in fixed fan speed mode and the lag in manual adjustment by users in fixed fan speed mode. It ensures that users' personalized airflow needs are met within the comfort range, ultimately significantly improving the synergy between the user experience and system energy efficiency of the air conditioner.

[0064] Furthermore, Figure 3 A flowchart illustrating another embodiment of the air conditioner indoor fan control method provided by the present invention is shown below. Figure 3 The method shown is in Figure 1 Based on the control method of the indoor fan of the air conditioner shown, when the controller of the indoor fan is based on such Figure 1 After the indoor fan is controlled to run at the first target speed, the controller of the indoor fan also obtains the coil temperature or outlet air temperature of the indoor fan through S201, and determines the second target speed corresponding to the coil temperature or outlet air temperature through S202, thereby controlling the indoor fan to run at the second target speed to ensure that the outlet air temperature is in the high-efficiency cooling range.

[0065] In another embodiment, such as Figure 3 The method allows for the acquisition of the indoor fan coil temperature or outlet air temperature while controlling the indoor fan to operate at a first target speed, and then determining a second target speed corresponding to that temperature, thereby controlling the indoor fan to operate at the second target speed. In this embodiment, the first target speed can be a preset speed of the indoor fan, or a speed corresponding to the current state of the air conditioner.

[0066] Specifically, given the lack of a real-time feedback mechanism for coil temperature or outlet air temperature in existing technologies, it is impossible to dynamically fine-tune the airflow to maintain optimal cooling efficiency, leading to energy efficiency fluctuations. The air conditioner indoor fan control method provided by this invention introduces a coil temperature or outlet air temperature feedback mechanism to monitor changes in coil or outlet air temperature in real time and fine-tune the airflow based on the feedback data. For example, when the coil temperature rises abnormally, the system automatically increases the airflow to enhance heat exchange efficiency.

[0067] Therefore, the indoor fan control method provided in this embodiment solves the dynamic optimization problem of cooling efficiency through a closed-loop feedback mechanism. By fine-tuning the indoor fan airflow in real time based on the target speed, it avoids efficiency reduction caused by coil condensation or uneven cooling distribution. For example, in high-temperature environments, the indoor fan controller can determine whether the heat exchange efficiency has decreased through coil temperature feedback and adjust the airflow in real time to maintain optimal cooling. Furthermore, through dynamic fine-tuning, the system can adapt to changes in environmental heat load, avoiding energy efficiency reduction caused by fluctuations in heat exchange efficiency under fixed airflow mode. In addition, real-time feedback can eliminate the interference of temperature measurement errors on the control logic, further improving system stability and significantly enhancing the sustainability of cooling efficiency and the system's environmental adaptability.

[0068] In another embodiment of the invention, the controller of the indoor fan can also construct a user behavior model through historical user operation data. For example, it can acquire data such as the frequency of fan speed adjustment and the time of day when the user uses the air conditioner, and combine this data with machine learning algorithms to predict the user's potential demand for airflow, dynamically adjusting the control strategy. This solves the problem of passive response in the control strategy by learning user behavior patterns. For example, the system can automatically activate a performance-priority strategy during periods when the user is accustomed to high temperatures, and prioritize maintaining low fan speed operation during periods of low activity. Through predictive adjustments, the system can anticipate changes in user demand, reduce manual intervention, and improve the consistency of the user experience. Furthermore, it can dynamically adapt to user preferences, avoiding the abuse of "frenzy mode" in unnecessary scenarios, thereby reducing energy consumption, extending equipment life, and improving the responsiveness to personalized user needs and energy efficiency optimization capabilities.

[0069] In another embodiment of the invention, the controller of the indoor fan can also construct a room temperature prediction model based on historical room temperature change data and environmental parameters. For example, it can predict the room temperature trend over a period of time, thereby adjusting the speed of the indoor fan to the target speed in advance. For instance, before predicting that the room temperature is about to enter the "uncomfortable" range, it can proactively increase the fan speed to avoid the user perceiving temperature fluctuations. By intervening in advance, the system can reduce the impact of sudden room temperature changes on user comfort, while optimizing cooling efficiency to dynamically predict and adapt to changes in environmental heat load, avoiding control failures under fixed threshold modes, and improving the foresight and stability of the air conditioner under complex heat load scenarios.

[0070] Furthermore, in another embodiment of the present invention, when the controller of the indoor fan executes the control method, it can also divide the room temperature into multiple room temperature gradient ranges and provide different preset functions for different room temperature gradient ranges to achieve different speed adjustment strategies for different ranges. For example, when the indoor temperature is higher, a preset function based on exponential change is used to achieve faster cooling; when the indoor temperature is comfortable, a function based on linear growth is used to achieve more stable temperature changes. Thus, through the division of multiple temperature ranges, the system can adopt differentiated control strategies for different temperature requirements. For example, in the high-temperature zone, an exponential growth function is used to quickly increase the speed so that the indoor fan outputs the maximum air volume; in the medium-temperature zone, the speed is gradually reduced to restore the user setting. This solves the problem that the traditional single control strategy in the prior art cannot adapt to complex temperature scenarios. In particular, while shortening the cooling time, it improves the energy efficiency ratio in the comfort zone and reduces the temperature fluctuation of the air conditioner, further improving the stability of the user's perception and the user experience.

[0071] In the foregoing embodiments of the present invention, the control method for the indoor fan of an air conditioner provided by the embodiments of the present invention has been described. In order to realize the functions of the methods provided by the embodiments of the present invention, the control device of the indoor fan of the air conditioner, as the execution subject, can implement the above functions through hardware structure and / or software modules. Whether a certain function is executed by hardware structure, software module, or hardware structure plus software module depends on the specific application and design constraints of the technical solution.

[0072] For example, Figure 4 This is a schematic diagram of an embodiment of the control device for the indoor fan of an air conditioner provided by the present invention, as shown below. Figure 4 The control device 1000 for the indoor fan of the air conditioner shown includes: an acquisition module 1001, a determination module 1002, and a control module 1003. The acquisition module 1001 is used to acquire the indoor ambient temperature when the air conditioner enters its extreme speed mode; the determination module 1002 is used to determine a first target speed corresponding to the indoor ambient temperature; and the control module 1003 is used to control the indoor fan to operate at the first target speed.

[0073] In one embodiment, such as Figure 4 In the control device 1000 shown, the acquisition module 1001 is used to acquire the coil temperature or outlet air temperature of the indoor fan when the indoor fan is running at the first target speed; the determination module 1002 is used to determine the second target speed corresponding to the coil temperature or outlet air temperature; and the control module 1003 is used to control the indoor fan to run at the second target speed.

[0074] like Figure 4 The specific implementation method and principle of the control device 1000 for the air conditioner indoor fan shown can be referred to the control method of the corresponding air conditioner indoor fan mentioned above. The implementation method and principle are the same and will not be repeated here.

[0075] It should be understood that the division of the various modules in the above device is merely a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, these modules can be implemented entirely in software via processing element calls; they can be fully implemented in hardware; or some modules can be implemented by processing element calls to software, while others are implemented in hardware. For example, a module can be a separately established processing element, or it can be integrated into a chip within the above device.
