[0104] With the advancement of science and technology, modern society is seeing the emergence of an increasing number of home appliances and technological products, providing users with comprehensive services and convenience. Among the many smart home appliances, smart air conditioners offer diverse functions and a wide range of applications. They effectively regulate indoor temperature, providing users with a comfortable living and working environment. Furthermore, smart air conditioners can lower temperatures to combat hot weather, control humidity to improve air quality, purify the air to remove pollutants, increase air circulation to maintain fresh air, and reduce noise. With these diverse functions, smart air conditioners not only improve users' quality of life but also play a vital role in industrial production, healthcare, and other fields, becoming an indispensable smart device in modern society.

[0105] In existing technologies, smart air conditioners can provide users with air flow of different intensities and speeds by controlling the fan speed, thereby meeting the user's demand for air flow. Currently, variable-frequency air conditioning systems divide different intervals by cross-dividing the temperature and frequency parameters, realizing intelligent adjustment of the fan speed, setting the corresponding speed according to different intervals, and providing convenient and effective wind speed control.

[0106] However, the fan operation mode of the variable frequency air conditioner can only perform the most basic speed control settings, running at a fixed speed in a fixed frequency range and a fixed temperature range, which makes the variable frequency air conditioning system have the limitation of not being able to flexibly increase the speed during actual operation; under high temperature and high load conditions, it runs at high speed, and cannot effectively reduce the fan speed under low temperature and low load, or it still runs at high speed under high temperature and low load, causing energy waste in the system; in addition, in ECO energy-saving mode or when the set temperature is about to be reached and shut down, the system can only maintain a higher speed and cannot flexibly reduce the speed, resulting in poor energy efficiency and a lack of intelligent speed regulation function, thereby limiting the performance of the variable frequency air conditioning system in terms of energy saving and comfort.

[0107] In response to the above problems, the present application provides a wind speed control method for smart home appliances.

[0108] First, the implementation scenarios involved in this application are described.

[0109] With the development of science and technology, the services that smart home appliances can provide to users are becoming more and more diverse. Among them, smart air conditioners are one of the indispensable smart devices in people's daily lives. Smart air conditioners can adjust the user's indoor temperature, keep the air clean, adjust the humidity, provide heating functions, and achieve comfortable and convenient environmental management through energy-saving control and remote operation.

[0110] The cooling mode of a smart air conditioner can effectively lower indoor temperatures and provide a comfortable environment. It plays an important role in various scenarios, including homes, commercial buildings, medical institutions, schools, and entertainment venues. Furthermore, a smart air conditioner can optimize its energy consumption by flexibly adjusting the fan speed, thereby providing users with a comfortable indoor experience while reducing energy consumption, while also improving energy efficiency and reducing energy waste. The smart air conditioner involved in this application can, for example, be a smart air conditioner equipped with a variable-frequency air conditioning control system equipped with a wind speed adjustment module.

[0111] For example, the control system of the smart air conditioner calls the wind speed adjustment module to further reduce the speed of the outdoor fan when the smart air conditioner is under low load; and adjusts the speed of the outdoor fan automatically according to the current system status of the smart air conditioner, thereby reducing the energy consumption of the smart air conditioner and correspondingly reducing the fan noise of the outdoor unit of the smart air conditioner.

[0112] The wind speed control method for smart home appliances provided in this application adds a temperature definition relationship to the control program of the smart home appliance and obtains multiple sensor detection temperatures in real time. Based on the newly added temperature definition relationship and multiple real-time temperatures, it determines whether the smart home appliance should adjust the wind speed. When the multiple real-time temperatures meet the newly added temperature definition relationship, the wind speed of the smart home appliance is controlled to perform a step-by-step speed reduction process. During the speed reduction process of the smart home appliance, the wind speed adjustment operation that the smart home appliance can continue to perform is determined based on the real-time obtained temperature and the newly added temperature definition relationship. The adjustment operation includes: speed reduction process, wind speed maintenance process, and speed increase process. This method optimizes the control logic of the wind speed adjustment of the smart home appliance, reduces the noise generated when the smart home appliance is in use, realizes the intelligent adjustment of the fan speed without affecting the operation of the smart home appliance, reduces the operating energy consumption of the smart home appliance, and improves the user experience.

[0113] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0114] Figure 1 Schematic diagram of the process of the wind speed control method of the smart home appliance provided in the embodiment of the present application Figure 1 The execution subject of this embodiment can be, for example, a variable frequency air conditioning control system provided with a wind speed adjustment module. Figure 1 As shown, the wind speed control method of the smart home appliance provided in this embodiment includes:

[0115] S101: Obtain the air outlet temperature, cold outlet temperature and ambient temperature of the smart home appliance.

[0116] Among them, the exhaust temperature is used to indicate the temperature of the refrigerant gas discharged from the external fan of the smart home appliance after being compressed by the compressor. The cold outlet temperature is used to indicate the temperature of the compressed refrigerant gas when it is converted into liquid refrigerant after heat exchange treatment. The ambient temperature is used to indicate the outdoor temperature conditions of the space where the smart home appliance is located.

[0117] It can be understood that smart home appliances are equipped with a variety of sensors that can perform real-time detection of the internal and external environmental states of smart home appliances; the various sensors configured in smart home appliances include: temperature sensors, which can detect the temperature of different locations inside the smart home appliance in real time through the multiple temperature sensors that have been set up, and can also detect the temperature of the external environment of the smart home appliance in real time; the executor of this step is the control system of the smart home appliance, and the control system can obtain temperature detection data from multiple temperature sensors and analyze and process the obtained temperature detection data.

[0118] Through the multiple temperature sensors equipped in smart home appliances, the temperature of the refrigerant gas discharged from the external fan after being compressed by the compressor can be detected in real time; at the same time, the temperature of the compressed refrigerant gas when it is converted into liquid refrigerant after heat exchange treatment, as well as the outdoor temperature conditions of the space where the smart home appliance is located, can also be detected in real time; and the three currently detected temperature values ​​are respectively determined as the exhaust temperature, the cold outlet temperature and the ambient temperature.

[0119] S102: Generate a first temperature relationship and a second temperature relationship according to the exhaust temperature, the cold outlet temperature, and the ambient temperature.

[0120] Among them, the first temperature relationship is used to determine whether the actual heat exchange of the external fan exceeds the expected heat exchange from the dimension of the temperature of the liquid refrigerant after heat exchange treatment; the second temperature relationship is used to determine whether the actual heat exchange of the external fan exceeds the expected heat exchange from the dimension of the temperature of the refrigerant gas discharged from the compressor.

[0121] It is understandable that when users use smart home appliances, they will adjust the setting parameters of smart home appliances according to their own usage needs to achieve flexible adjustment of the service intensity that smart home appliances can provide; in the process of using smart home appliances, there is a situation where the service intensity that smart home appliances can provide is much higher than the intensity required by the user. At this time, the smart home appliances will waste energy. In this case, the control system of the smart home appliances can adjust its own setting parameters to reduce the service intensity of the smart home appliances while meeting the user's usage needs. For example, when a user uses a smart air conditioner for cooling, if the actual heat exchange rate of the external fan does not exceed the expected heat exchange rate, it means that the heat exchange rate that the smart air conditioner can provide is not much different from the heat exchange rate corresponding to the user's actual usage needs. At this time, the smart air conditioner does not need to adjust the cooling intensity of the smart air conditioner, and there is no energy waste; if the actual heat exchange rate of the external fan exceeds the expected heat exchange rate, it means that the heat exchange rate that the smart air conditioner can provide is much greater than the heat exchange rate corresponding to the user's usage needs. At this time, the smart air conditioner can reduce the cooling intensity of the smart air conditioner without affecting the cooling service currently provided by the smart air conditioner to the user.

[0122] The first temperature relationship and the second temperature relationship are essentially the same, and both can reflect whether there is a difference between the actual heat exchange capacity of the current smart home appliance and the heat exchange capacity actually required by the user. That is to say, the actual heat exchange capacity that the current smart home appliance can provide can meet the heat exchange capacity actually required by the user, and there is excess heat exchange capacity; the first temperature relationship is based on the dimension of the refrigerant gas temperature after compression by the external fan to determine whether the smart home appliance has excess heat exchange capacity; the second temperature relationship is based on the dimension of the liquid refrigerant temperature after heat exchange treatment to determine whether the smart home appliance has excess heat exchange capacity; when a smart home appliance has excess heat exchange capacity, maintaining this state for a long time will lead to energy waste and shortened equipment life. In combination with the historical operation data of the smart home appliance, starting from the dimension of the temperature of the refrigerant gas after compression by the external fan, when it is determined that the smart home appliance does not have excess heat exchange, the difference between the cold outlet temperature and the ambient temperature in the corresponding historical data is determined, and the difference is determined as the reference difference, and the reference difference can determine the difference between the actual heat exchange of the smart home appliance and the heat exchange actually required by the user, thereby assisting in the measurement of the first temperature relationship; starting from the dimension of the temperature of the liquid refrigerant after heat exchange treatment, when it is determined that the smart home appliance does not have excess heat exchange, the exhalation average value of the exhalation temperature in the corresponding historical data is determined, and the exhalation average value can determine the difference between the actual heat exchange of the smart home appliance and the heat exchange actually required by the user, thereby assisting in the measurement of the second temperature relationship. This application does not impose any special restrictions on the method for determining the reference difference used to determine the first temperature relationship and the exhalation average value used to determine the second temperature relationship.

[0123] Based on the currently obtained cold outlet temperature and ambient temperature, the difference between the cold outlet temperature and the ambient temperature is calculated, and the difference can reflect the difference between the temperature of the gas discharged by the external fan after heat exchange treatment and the actual ambient temperature; the difference is compared with the reference difference to obtain a comparison relationship between the differences, and the comparison relationship is determined as a first temperature relationship; based on the currently obtained exhalation temperature, the exhalation temperature is compared with the exhalation average value to obtain a comparison relationship between the two, and the comparison relationship is determined as a second temperature relationship.

[0124] For example, the air outlet temperature obtained by the control system of the intelligent air conditioner is T t , the cold outlet temperature is T l and the ambient temperature is T w , the reference difference can be A, the exhaled average value can be B; calculate the difference between the cold outlet temperature and the ambient temperature: T l -T w , T l -T w Compare with the reference difference A, and determine the comparison relationship as the first temperature relationship; tThe temperature is compared with the exhaled average value B, and the comparison relationship is determined as the second temperature relationship.

[0125] S103: Acquire a preset energy-saving condition of the smart home appliance, and determine whether the first temperature relationship and the second temperature relationship meet the preset energy-saving condition.

[0126] The preset energy-saving condition may be, for example, that the difference between the cold outlet temperature and the ambient temperature is less than a reference difference, and the exhaust air temperature is less than an average exhaust air value.

[0127] The purpose of this step of judging whether the first temperature relationship and the second temperature relationship meet the preset energy-saving conditions is to determine, based on different temperature dimensions, whether the actual heat exchange of the smart home appliance at that time still has excess heat exchange after meeting the heat exchange required by the user.

[0128] It can be understood that there are three comparison situations in the first temperature relationship, namely: the difference between the cold outlet temperature and the ambient temperature is greater than the reference difference, the difference between the cold outlet temperature and the ambient temperature is equal to the reference difference, and the difference between the cold outlet temperature and the ambient temperature is less than the reference difference; there are three comparison situations in the second temperature relationship, namely: the exhalation temperature is greater than the exhalation average value, the exhalation temperature is equal to the exhalation average value, and the exhalation temperature is less than the exhalation average value; among them, when the first temperature relationship and the second temperature relationship are respectively less than the relationship, the actual heat exchange that can be provided by the external fan exceeds the expected heat exchange. If the smart home appliance maintains the current state, it will lead to energy waste of the smart home appliance.

[0129] If the first temperature relationship and the second temperature relationship meet the preset energy-saving conditions, it means that the actual heat exchange amount of the smart home appliance at that time has excess heat exchange amount after meeting the actual heat exchange amount required by the user. At this time, the smart home appliance can be controlled to perform energy-saving processing, that is, the smart home appliance can be controlled to enter the wind speed adjustment mode, so that the wind speed of the external fan can be intelligently adjusted to achieve the effect of energy saving.

[0130] Optionally, the method further includes:

[0131] If the first temperature relationship and / or the second temperature relationship do not meet the preset energy-saving conditions, the smart home appliance is controlled not to enter the wind speed adjustment mode; the exhaust air temperature, the cold outlet temperature and the ambient temperature are re-acquired; the first temperature relationship and the second temperature relationship are updated according to the new exhaust air temperature, the new cold outlet temperature and the new ambient temperature respectively; it is determined whether the new first temperature relationship and the new second temperature relationship meet the preset energy-saving conditions; if the new first temperature relationship and the new second temperature relationship meet the preset energy-saving conditions, the smart home appliance is controlled to enter the wind speed adjustment mode.

[0132] If the first temperature relationship and / or the second temperature relationship does not meet the preset energy-saving conditions, it indicates that the actual heat exchange of the smart home appliance at that time does not have excess heat exchange after meeting the heat exchange actually required by the user. At this time, the smart home appliance is controlled not to enter the wind speed adjustment mode; and the exhalation temperature, the cold outlet temperature and the ambient temperature are re-acquired, and the first temperature relationship and the second temperature relationship are updated based on the new exhalation temperature, the new cold outlet temperature and the new ambient temperature, that is, the smart home appliance is re-judged whether to enter the wind speed adjustment mode using the multiple temperatures currently re-acquired; it is judged whether the new first temperature relationship and the new second temperature relationship meet the preset energy-saving conditions; if the new first temperature relationship and the new second temperature relationship meet the preset energy-saving conditions, it indicates that the actual heat exchange of the smart home appliance at that time still has excess heat exchange after meeting the heat exchange actually required by the user. At this time, the smart home appliance is controlled to enter the wind speed adjustment mode, so that the wind speed of the external fan can be intelligently regulated to achieve energy-saving effects.

[0133] S104: If the first temperature relationship and the second temperature relationship meet the preset energy-saving condition, control the smart home appliance to enter a wind speed adjustment mode.

[0134] The wind speed control method for a smart appliance provided in this embodiment obtains the smart appliance's outlet temperature, outlet temperature, and ambient temperature, and generates a first temperature relationship and a second temperature relationship based on the outlet temperature, outlet temperature, and ambient temperature. The method also obtains a preset energy-saving condition for the smart appliance and determines whether the first temperature relationship and the second temperature relationship meet the preset energy-saving condition. If the first temperature relationship and the second temperature relationship meet the preset energy-saving condition, the smart appliance is controlled to enter a wind speed adjustment mode, flexibly adjusting the wind speed of the smart appliance. This method optimizes the control logic for wind speed adjustment in smart appliances, enabling intelligent adjustment of fan speed without affecting the operation of the smart appliance, thereby improving the user experience.

[0135] Figure 2 Schematic diagram of the process of the wind speed control method of the smart home appliance provided in the embodiment of the present application Figure 2 .like Figure 2 As shown, this embodiment Figure 1 Based on the embodiment, the wind speed control method of the smart home appliance is described in detail. The wind speed control method of the smart home appliance shown in this embodiment includes:

[0136] S201: Obtain the air outlet temperature, cold outlet temperature and ambient temperature of the smart home appliance.

[0137] Step S201 is similar to the above-mentioned step S101 and will not be described again here.

[0138] S202: Obtain a data definition table of the smart home appliance.

[0139] S203: Determine a preset exhalation temperature and a preset temperature difference according to the data definition table.

[0140] Among them, the data definition table is used to store parameter information related to the first temperature relationship and the second temperature relationship; the preset exhaust temperature is used to indicate the reference temperature value for determining whether the smart home appliance has excess heat exchange based on the dimension of the liquid refrigerant temperature after heat exchange treatment; the preset temperature difference is used to indicate the reference temperature value for determining whether the smart home appliance has excess heat exchange based on the dimension of the refrigerant gas temperature after compression by the external fan.

[0141] A data definition table for the smart home appliance is obtained and filtered to determine a reference temperature value that can be used to determine whether the smart home appliance currently has excess heat exchange capacity. The number of reference temperature values ​​currently obtained corresponds to the first temperature relationship and the second temperature relationship. That is, two reference temperature values ​​can be obtained currently, namely the preset exhalation temperature and the preset temperature difference.

[0142] For example, the preset exhaled air temperature may be 86° C., and the preset temperature difference may be 3° C.

[0143] S204: Generate a cold outlet temperature difference according to the cold outlet temperature and the ambient temperature.

[0144] The cold outlet temperature difference value is used to indicate the temperature difference between the cold outlet temperature and the ambient temperature.

[0145] For example, if the currently acquired cold outlet temperature is 37°C and the ambient temperature is 35°C, 37°C-35°C=2°C, then the corresponding cold outlet temperature difference is 2°C.

[0146] S205: Compare the cold outlet temperature difference with the preset temperature difference to obtain a comparison relationship between the cold outlet temperature difference and the preset temperature difference, and determine the comparison relationship as a first temperature relationship.

[0147] S206: Compare the exhaled air temperature with the preset exhaled air temperature to obtain a comparison relationship between the exhaled air temperature and the preset exhaled air temperature, and determine the comparison relationship as a second temperature relationship.

[0148] The cold outlet temperature difference is compared with the preset temperature difference to determine the size relationship between the two, and then determine whether the actual heat exchange of the external fan exceeds the expected heat exchange, and the comparison relationship between the obtained cold outlet temperature difference and the preset temperature difference is determined as the first temperature relationship; the exhaust air temperature is compared with the preset exhaust air temperature to determine the size relationship between the two, and then determine whether the actual heat exchange of the external fan exceeds the expected heat exchange, and the comparison relationship between the obtained exhaust air temperature and the preset exhaust air temperature is determined as the second temperature relationship.

[0149] It is understandable that the number of reference temperature values ​​is correlated with the number of temperature relationships used to determine whether there is excess heat exchange in the smart appliance. This application does not impose any special restrictions on the number of temperature relationships.

[0150] For example, the air outlet temperature obtained by the control system of the intelligent air conditioner is T t , the cold outlet temperature is T l and the ambient temperature is T w , the preset exhalation temperature is 86℃, and the preset temperature difference is 3℃; then, the first temperature relationship is T l -T w The second temperature relationship is T t The relationship between the preset exhalation temperature of 86℃.

[0151] S207: Acquire preset energy-saving conditions of the smart home appliance, and analyze and process the preset energy-saving conditions to obtain a first energy-saving condition and a second energy-saving condition.

[0152] The first energy-saving condition is used to indicate that the difference between the cold outlet temperature and the ambient temperature is less than a preset temperature difference, and the second energy-saving condition is used to indicate that the exhaust air temperature is less than a preset exhaust air temperature.

[0153] It can be understood that the preset energy-saving condition is composed of the union of the first energy-saving condition and the second energy-saving condition, that is, it includes all the requirements of both; the first energy-saving condition and the second energy-saving condition are the basic components of the preset energy-saving condition, and they together constitute the complete requirements of the preset energy-saving condition, representing the control system to determine whether the smart home appliance meets the energy-saving condition from different temperature dimensions.

[0154] S208: Determine whether the first temperature relationship satisfies the first energy-saving condition.

[0155] S209: If the first temperature relationship satisfies the first energy-saving condition, determine whether the second temperature relationship satisfies the second energy-saving condition.

[0156] The purpose of this step of judging whether the first temperature meets the first energy-saving condition is to determine whether the smart home appliance has excess heat exchange; the purpose of judging whether the second temperature meets the second energy-saving condition is also to determine whether the smart home appliance has excess heat exchange. The temperature dimensions for the two judgments are different, but the judgment results reflect the same essence.

[0157] If the first temperature relationship satisfies the first energy-saving condition and the second temperature relationship satisfies the second energy-saving condition, it indicates that the actual heat exchange amount of the smart home appliance at that time still has excess heat exchange after meeting the heat exchange amount actually required by the user. At this time, the preset control frequency and preset control time of the smart home appliance are obtained; among which, the preset control frequency can be, for example, 10 revolutions / 20 seconds, and the preset control time can be, for example, 20 seconds.

[0158] If the first temperature relationship does not meet the first energy-saving condition and / or the second temperature relationship does not meet the second energy-saving condition, it indicates that the actual heat exchange amount of the smart home appliance at that time does not have excess heat exchange after meeting the heat exchange amount actually required by the user. At this time, the smart home appliance is controlled not to enter the wind speed adjustment mode; and the exhaust air temperature, cold outlet temperature and ambient temperature are re-obtained, and it is again determined whether the first temperature relationship and the second temperature relationship determined based on the re-obtained exhaust air temperature, cold outlet temperature and ambient temperature meet the first energy-saving condition and the second energy-saving condition.

[0159] If the first temperature relationship does not satisfy the first energy-saving condition and / or the second temperature relationship does not satisfy the second energy-saving condition, it is necessary to reacquire the multiple sensor temperatures and re-determine whether the temperature relationship satisfies the energy-saving condition; wherein the time interval between the timing of reacquiring the multiple sensor temperatures and the timing of determining that the energy-saving condition is not satisfied can be consistent with the preset control duration. This application does not impose any special restrictions on the timing of reacquiring the multiple sensor temperatures.

[0160] This application does not impose any special restrictions on the order of determining whether the first temperature meets the second energy-saving condition and determining whether the second temperature meets the second energy-saving condition.

[0161] S210: If the first temperature relationship satisfies the first energy-saving condition and the second temperature relationship satisfies the second energy-saving condition, obtaining a preset control frequency and a preset control duration of the smart home appliance.

[0162] S211: Control the smart home appliance to enter a wind speed reduction phase, and reduce the speed of the smart home appliance according to the preset control frequency and the preset control duration.

[0163] Among them, the wind speed adjustment mode includes: wind speed reduction stage, wind speed maintenance stage and wind speed increase stage.

[0164] It can be understood that when the first temperature relationship satisfies the first energy-saving condition and the second temperature relationship satisfies the second energy-saving condition, the actual heat exchange capacity that the current smart home appliance can provide can meet the heat exchange required by the user's actual needs, and there is excess heat exchange. At this time, the smart home appliance can reduce the actual heat exchange capacity that can be provided, that is, when the smart home appliance first enters the wind speed adjustment mode, it first enters the wind speed reduction stage, reduces the wind speed of the smart home appliance's external fan, reduces the actual heat exchange capacity that the current smart home appliance can provide, and thus achieves energy-saving effects.

[0165] After determining that the smart home appliance has entered the wind speed adjustment mode and has obtained the preset control frequency and the preset control duration, the smart home appliance is controlled to enter the wind speed reduction stage, that is, the wind speed of the external fan of the current smart home appliance is reduced. At this time, the smart home appliance is reduced in speed according to the currently obtained preset control frequency, and the maintenance duration of the speed reduction process is consistent with the preset control duration; after the smart home appliance is reduced in speed, the external fan of the smart home appliance is controlled to run at the wind speed after the current speed reduction for a period of time, and the running time is consistent with the preset control duration.

[0166] For example, after determining that the smart home appliance enters the wind speed adjustment mode, the external fan of the smart air conditioner is controlled to reduce the wind speed of the external fan at a reduction frequency of 10 revolutions / 20 seconds, and the speed reduction process is maintained for 20 seconds; when the speed reduction process is completed, the smart air conditioner is controlled to run at the reduced wind speed for 20 seconds, and the sensor temperature is obtained again after 20 seconds, so as to adjust the wind speed of the external fan again.

[0167] S212: Re-acquire the exhaled air temperature, the cold outlet temperature, and the ambient temperature.

[0168] S213: updating the first temperature relationship and the second temperature relationship according to the new exhaled air temperature, the new cold outlet temperature, and the new ambient temperature.

[0169] It is understandable that after the smart home appliance performs the speed reduction processing, the actual heat exchange capacity of the external fan changes, so it is necessary to re-acquire the temperature of the corresponding sensor to determine how to adjust the wind speed of the external fan; and this determination determines whether the smart home appliance will continue to reduce the speed after the current speed reduction processing, or enter the wind speed maintenance stage or the wind speed increase stage.

[0170] The exhaled air temperature, the cold outlet temperature and the ambient temperature are re-acquired, and the temperature difference between the new cold outlet temperature and the new ambient temperature is calculated to determine a new cold outlet temperature difference; the new cold outlet temperature difference is compared with the preset temperature difference to determine a new first temperature relationship; the new exhaled air temperature is compared with the preset exhaled air temperature to determine a new second temperature difference.

[0171] S214: Determine whether the new first temperature relationship and the new second temperature relationship satisfy the first energy-saving condition and the second energy-saving condition, respectively.

[0172] This step of judging whether the new first temperature relationship and the new second temperature relationship satisfy the first energy-saving condition and the second energy-saving condition respectively is to determine whether the smart home appliance continues to perform the speed reduction process.

[0173] If the new first temperature relationship and the new second temperature relationship meet the first energy-saving condition and the second energy-saving condition respectively, it indicates that the actual heat exchange of the current external fan has excess heat exchange after meeting the actual heat exchange required by the user. At this time, the smart home appliance continues to be slowed down for the second time according to the preset control frequency and preset control time.

[0174] If the new first temperature relationship does not meet the first energy-saving condition and / or the new second temperature relationship does not meet the second energy-saving condition, it indicates that the actual heat exchange of the current external fan does not have excess heat exchange after meeting the actual heat exchange requirements of the user. At this time, it is necessary to further judge the new first temperature relationship and the new second temperature relationship to determine the current wind speed adjustment direction of the smart home appliance.

[0175] Preferably, the wind speed adjustment mode includes: a wind speed maintenance stage and a wind speed increase stage, and the method further includes:

[0176] If the new first temperature relationship does not meet the first energy-saving condition and / or the new second temperature relationship does not meet the second energy-saving condition, the preset control temperature of the wind speed adjustment mode is obtained; a new outlet temperature difference is generated according to the new outlet temperature and the new outlet temperature; a preset temperature range corresponding to the wind speed maintenance stage is generated according to the preset outlet temperature, the preset temperature difference and the preset control temperature; it is determined whether the new outlet temperature difference and / or the new outlet temperature is greater than the upper limit of the preset temperature range; if so, the smart home appliance is controlled to enter the wind speed increase stage, and the smart home appliance is increased according to the preset control frequency and the preset control time; if not, the smart home appliance is controlled to enter the wind speed maintenance stage, and the smart home appliance is maintained according to the preset control time.

[0177] The preset control temperature may be 1°C, for example; the preset temperature interval is used to indicate a temperature range with a preset temperature difference or a preset exhalation temperature as a lower limit and a sum of the preset temperature difference or the preset exhalation temperature and the preset control temperature as an upper limit.

[0178] If the new first temperature relationship does not satisfy the first energy-saving condition and / or the new second temperature relationship does not satisfy the second energy-saving condition, it indicates that the actual heat exchange capacity of the current outdoor fan does not have excess heat exchange capacity after satisfying the heat exchange capacity actually required by the user. In this case, a preset control temperature for the wind speed adjustment mode is obtained; a new cold outlet temperature difference is generated based on the new outlet temperature and the new cold outlet temperature; the preset temperature difference is used as the lower limit of the temperature interval, and the sum of the preset temperature difference and the preset control temperature is used as the upper limit of the temperature interval, thereby generating a temperature range based on the first temperature relationship, and determining this temperature range as the preset temperature interval corresponding to the wind speed maintenance stage; the preset outlet temperature is used as the lower limit of the temperature interval, and the sum of the preset outlet temperature and the preset control temperature is used as the upper limit of the temperature interval, thereby generating a temperature range based on the second temperature relationship, and determining this temperature range as the preset temperature interval corresponding to the wind speed maintenance stage; wherein the preset temperature interval corresponding to the first temperature relationship can be determined as the first preset temperature interval, and the preset temperature interval corresponding to the second temperature relationship can be determined as the second preset temperature interval, so as to distinguish preset temperature intervals of different temperature dimensions in the wind speed maintenance stage.

[0179] The purpose of judging whether the new cold outlet temperature difference and / or the new exhaust air temperature is greater than the upper limit of the preset temperature range in this step is to determine whether the smart home appliance enters the wind speed increase stage, that is, whether to perform speed increase processing.

[0180] If the new outlet temperature difference and / or the new exhaust temperature is greater than the upper limit of the preset temperature range, it indicates that the new outlet temperature difference is greater than the upper limit of the first preset temperature range and / or the new exhaust temperature is greater than the upper limit of the second preset temperature range. At this time, the judgment of any temperature dimension can determine that the actual heat exchange rate of the current external fan does not have excess heat exchange after meeting the actual heat exchange rate required by the user. Then, the smart home appliance is controlled to enter the wind speed increase stage, and the smart home appliance is speeded up according to the preset control frequency, and the maintenance time of the speed increase process is consistent with the preset control time.

[0181] If the new cold outlet temperature difference and the new exhaust air temperature are both not greater than the upper limit of the preset temperature range, it indicates that at least one of the new cold outlet temperature difference and the new exhaust air temperature is in the preset temperature range, that is, the judgment of at least one temperature dimension can determine that the actual heat exchange of the current external fan does not have excess heat exchange after meeting the heat exchange required by the user. At this time, the smart home appliance is controlled to enter the wind speed maintenance stage, and the wind speed maintenance processing of the smart home appliance is performed according to the preset control time.

[0182] For example, the preset control temperature can be 1°C, the preset temperature difference is A°C, and the preset exhalation temperature is B°C. Then the first preset temperature range is (A, A + 1), and the second preset temperature range is (B, B + 1); the newly obtained current cold outlet temperature difference T l -T w and the new exhalation temperature T t are respectively compared with the first preset temperature range and the second preset temperature range; 1) A < T l -T w < A + 1, B < T t < B + 1; 2) A < T l -T w < A + 1, T t < B; 3) T l -T w < A, B < T t < B + 1; Each time a determination is made, if any of the above conditions is met, it enters the wind speed holding stage; during the operation of the external fan, if B + 1 < T t ; A + 1 < T l -T w ; Each time a determination is made, if any of the above conditions is met, it enters the wind speed increasing stage.

[0183] [[ID=3三十三]]Preferably, before performing the speed increase process on the smart home appliance according to the preset control frequency and preset control duration, the method further includes:

[0184] Obtain the historical speed at which the smart home appliance enters the wind speed adjustment mode, and determine the historical speed as the wind speed upper limit value in the wind speed increase stage; obtain the current speed of the smart home appliance in real time, and determine whether the current speed is less than the wind speed upper limit value; if the current speed is less than the wind speed upper limit value, continue to perform the speed increase process on the smart home appliance according to the preset control frequency and preset control duration; if the current speed is not less than the wind speed upper limit value, control the smart home appliance to exit the wind speed adjustment mode.

[0185] Among them, the historical speed is used to indicate the speed of the external fan corresponding to when the smart home appliance enters the wind speed adjustment mode.

[0186] It can be understood that the adjustment of the wind speed of the smart home appliance is limited. On the premise of meeting the user's usage requirements, there is no possibility of long-term continuous speed reduction processing, and the purpose of this wind speed adjustment mode is to intelligently adjust the fan speed to meet the energy-saving requirements while meeting the user's usage requirements. Therefore, after the external fan is subjected to the speed increase process, the actual heat exchange amount provided by the external fan still cannot meet the heat exchange amount corresponding to the user's usage requirements. At this time, the smart home appliance needs to exit this wind speed adjustment mode to preferentially meet the user's usage requirements.

[0187] The fan speed corresponding to when the smart home appliance enters the wind speed adjustment mode is determined as the wind speed upper limit value in the wind speed increase stage; when the smart home appliance enters the wind speed increase stage, the fan speed of the smart home appliance is obtained in real time, and the relationship between the fan speed and the wind speed upper limit value is determined; if the current speed is less than the wind speed upper limit value, it indicates that the actual heat exchange capacity that the external fan can provide cannot meet the heat exchange capacity corresponding to the user's usage needs, but the current wind speed is still within the controllable range of the wind speed adjustment mode, and there is a possibility that the smart home appliance will exit the wind speed increase stage after the wind speed is increased, that is, after the wind speed is increased, there is no excess heat exchange capacity of the external fan, therefore, the smart home appliance continues to be increased in speed according to the preset control frequency and preset control time; if the current speed is not less than the wind speed upper limit value, it indicates that after the speed increase process is performed and the wind speed reaches the upper limit value, the actual heat exchange capacity that the external fan can provide still cannot meet the heat exchange capacity corresponding to the user's usage needs, at this time, the smart home appliance is controlled to exit the wind speed adjustment mode, and the smart home appliance is controlled to give priority to meeting the user's usage needs.

[0188] S215: If the new first temperature relationship and the new second temperature relationship satisfy the first energy-saving condition and the second energy-saving condition respectively, the smart home appliance is subjected to a secondary speed reduction process according to the preset control frequency and the preset control duration.

[0189] The wind speed control method of the smart home appliance provided in this embodiment obtains the air outlet temperature, cold outlet temperature, ambient temperature and data definition table of the smart home appliance, and determines the preset air outlet temperature and the preset temperature difference according to the data definition table; generates the cold outlet temperature difference based on the cold outlet temperature and the ambient temperature; compares the cold outlet temperature difference with the preset temperature difference, and the air outlet temperature with the preset air outlet temperature, respectively, to obtain the comparison relationship between the cold outlet temperature difference and the preset temperature difference, and between the air outlet temperature and the preset air outlet temperature, and determines the obtained comparison relationship as the first temperature relationship and the second temperature relationship respectively; obtains the preset energy-saving condition of the smart home appliance, analyzes and processes the preset energy-saving condition, obtains the first energy-saving condition and the second energy-saving condition, and judges respectively Whether the first temperature relationship satisfies the first energy-saving condition and whether the second temperature relationship satisfies the second energy-saving condition; if the first temperature relationship satisfies the first energy-saving condition and the second temperature relationship satisfies the second energy-saving condition, then the preset control frequency and preset control duration of the smart home appliance are obtained, the smart home appliance is controlled to enter the wind speed reduction stage, and the smart home appliance is reduced in speed according to the preset control frequency and preset control duration; after the smart home appliance is reduced in speed, the outlet temperature, the cold outlet temperature and the ambient temperature are re-acquired, the first temperature relationship and the second temperature relationship are updated respectively, and whether the updated first temperature relationship and the second temperature relationship meet the first energy-saving condition and the second energy-saving condition is re-determined, and the wind speed of the smart home appliance is flexibly adjusted based on the real-time determination result. This method optimizes the control logic of the wind speed regulation of the smart home appliance, reduces the noise generated when the smart home appliance is in use, realizes the intelligent regulation of the fan speed without affecting the operation of the smart home appliance, reduces the operating energy consumption of the smart home appliance, and improves the user experience.
