[0081] With the continuous development of science and technology, the functions of intelligent household appliances are also constantly updated. In order to meet the increasing demand of people for life, various intelligent household appliances are constantly updated.

[0082] Among them, the intelligent air conditioner is an air conditioner with automatic adjustment function. The intelligent air conditioner system can analyze, judge and automatically open the functions of refrigeration, heating, dehumidification and air purification according to the signals transmitted by the temperature, humidity and air cleanliness sensors installed in the space where the intelligent air conditioner is located according to the pre-set indicators according to the external climate conditions; through the self-regulation of the operation mode of the intelligent air conditioner, the temperature in the space provided with the intelligent air conditioner is kept constant, and a better use environment is provided for the user.

[0083] However, at present, the types of air conditioners at home and abroad are various, widely applied, and various market problems are endless, and the noise problem of the air conditioner has been the biggest problem that causes headache. The noise of the air conditioner is the noise emitted by the intelligent air conditioning system during operation, including the noise generated by the fan and emitted into the room, and the regenerative noise at the end of the air pipe. The noise generated by the fan is the regular noise generated by the blade when rotating and the irregular noise caused by vortex. In the prior art, a fixed noise reduction scheme is mostly used to process these noises. Since the acceptable noise range of the user for the intelligent air conditioner is different under different external time states, the prior art cannot realize corresponding intelligent noise reduction processing according to the current external time state of the intelligent air conditioner, that is, intelligent noise reduction cannot be realized.

[0084] In view of the above problems, the present application provides an intelligent noise reduction control method.

[0085] Firstly, the implementation scenario involved in the present application is explained.

[0086] With the universal application of intelligent household appliances, the intelligent air conditioner is mostly arranged in a space where the user often moves, such as a bedroom, to provide better use experience for the user. In order to better meet the use demand of the user, the intelligent household appliance is provided with various detection devices, which can realize real-time detection of the noise of the environment where the intelligent household appliance is located. According to different detection results, different processing schemes are adopted, so that the noise reduction control of the intelligent household appliance is more intelligent. The intelligent household appliance involved in the present application may be, for example, an intelligent household appliance provided with a noise detection device.

[0087] The intelligent household appliance is usually arranged at a position convenient for the user to use, for example, the intelligent air conditioner is usually arranged indoors to bring fresh outdoor air into the room. During the use of the intelligent air conditioner by the user, the noise generated by the intelligent air conditioner is also changing with the change of the use time. The noise detection device arranged on the outdoor unit of the intelligent air conditioner is used to detect the noise value generated by the outdoor unit in real time, and in combination with the time state of the current use of the intelligent air conditioner, a suitable noise reduction scheme is selected to reduce the noise of the outdoor unit of the current intelligent household appliance, so as to realize intelligent noise reduction of the outdoor unit.

[0088] The intelligent noise reduction control method provided in the application determines the current operating frequency band of the smart home appliance, acquires different noise thresholds according to different operating frequency bands, detects the noise value generated by the outdoor unit of the smart home appliance according to a preset detection frequency, performs frequency reduction and frequency increase processing on the operating frequency of the outdoor unit that triggers the noise reduction condition after the detection result meets the noise reduction condition, determines the operating frequency corresponding to the minimum noise value generated as the target operating frequency of the current outdoor unit according to the results of the frequency reduction and frequency increase processing, and controls the outdoor unit of the smart home appliance to operate at the target operating frequency. The method realizes intelligent noise reduction processing of the smart home appliance, improves the working efficiency of the smart home appliance, realizes frequency band noise reduction for different operating environments, provides a suitable activity environment for the user, and improves the user experience.

[0089] The technical solutions of the application and how the technical solutions of the application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0090] Figure 1 The flow of the intelligent noise reduction control method provided in the embodiments of the application Figure 1 The execution subject of the embodiment can be, for example, a control device of a smart home appliance. As shown in Figure 1 The intelligent noise reduction control method provided in the embodiment includes the following steps.

[0091] S101: Acquire the first noise value of the outdoor unit of the smart home appliance and the current operating frequency of the outdoor unit.

[0092] The first noise value is used to determine whether the outdoor unit of the current smart home appliance needs to be subjected to noise reduction processing, and the operating frequency is used to indicate the number of rotations per second of the compressor of the smart home appliance.

[0093] It can be understood that the outdoor unit of the smart home appliance is provided with a noise detection device for real-time detection of the noise generated by the outdoor unit. According to the setting position of the noise detection device for the outdoor unit, it can be determined that the noise detection device can also detect the external environmental noise, but the external environmental noise value detected at this time is much lower than the noise value generated by the outdoor unit. Therefore, although the external environmental noise can be detected, it is not the main detection target of the noise detection device, and the main detection target of the noise detection device is the noise generated by the outdoor unit, that is, the first noise value mainly reflects the noise generated by the outdoor unit.

[0094] The noise detection device arranged on the outdoor unit of the smart home appliance detects the noise generated by the outdoor unit in real time. According to the detection result, the current noise value is taken as the first noise value, and the operating frequency of the outdoor unit of the smart home appliance when the noise value generated by the outdoor unit is the first noise value is obtained.

[0095] For example, the noise detection device arranged on the outdoor unit of the smart home appliance can be a noise sensor. According to the noise sensor, the noise at the outdoor unit is detected in real time. If the first noise value currently obtained is 45 decibels, the current operating frequency of the outdoor unit corresponding to the noise value is 40 hertz.

[0096] S102: According to the first noise value and the current operating frequency, it is determined whether the outdoor unit is in a noise state.

[0097] The noise state is used to indicate that the noise generated by the smart home appliance currently interferes with the normal activities and rest of the user.

[0098] It can be understood that during the use of the smart home appliance, the operating mode of the smart home appliance is adjusted according to different needs of the user. Most users will select different operating modes according to different time periods, and the smart home appliance will select different operating frequencies according to different operating modes. The acceptable noise value range of the user under different external time states is also different, so it can be determined that the smart home appliance has different noise ranges corresponding to different operating frequencies for determining whether the outdoor unit is in a noise state. According to the first noise value currently obtained and the current operating frequency, the relationship between the first noise value and the corresponding noise range is determined, so as to determine whether the outdoor unit is in a noise state and whether the outdoor unit needs noise reduction processing.

[0099] According to the current operating frequency of the outdoor unit, the operating frequency range of the smart home appliance can be determined, and according to the corresponding operating frequency range, the noise range that meets the current operating frequency range can be obtained. It is determined whether the first noise value currently obtained is within the noise range, that is, whether the user can accept the smart home appliance to operate at the current frequency, and whether the noise generated by the outdoor unit is within the acceptable noise range of the user. If the first noise value is not within the noise range, it indicates that the noise generated by the current outdoor unit is not within the acceptable noise range of the user, and at this time it can be determined that the outdoor unit is in a noise state and the current outdoor unit needs noise reduction processing.

[0100] For example, if the currently acquired first noise value is 45 decibels, the current operating frequency of the outdoor unit corresponding to the noise value is 40 Hz, and the current operating frequency of the outdoor unit is in the low frequency range, the corresponding noise range is below 40 decibels, and 45 decibels is greater than 40 decibels, it indicates that the noise generated by the outdoor unit is not within the acceptable noise range of the user, and at this time it can be determined that the user is in a noise state; if the user is in this noise state for a long time, the user is prone to negative emotions such as irritability, and even affects the user's health, therefore, noise reduction processing needs to be performed on the outdoor unit.

[0101] S103: When the outdoor unit is in a noise state, optimizing the current operating frequency of the outdoor unit to obtain a target operating frequency.

[0102] The target operating frequency is used to indicate the operating frequency of the outdoor unit selected when noise reduction processing is performed on the noise generated by the outdoor unit of the smart home appliance.

[0103] When it is determined that the noise generated by the current outdoor unit causes the current user to be in a noise state, the current operating frequency of the outdoor unit is optimized; according to the optimization result, the operating frequency corresponding to the minimum noise value generated by the outdoor unit is obtained, and the operating frequency is determined as the target operating frequency.

[0104] For example, when the outdoor unit is in a noise state, if the currently acquired first noise value is 45 decibels, the current operating frequency of the outdoor unit corresponding to the noise value is 40 Hz, and the current operating frequency of the outdoor unit is in the low frequency range, the corresponding noise range is below 40 decibels, and 45 decibels is greater than 40 decibels, it indicates that the noise generated by the outdoor unit is not within the acceptable noise range of the user, and at this time it can be determined that the user is in a noise state; if the user is in this noise state for a long time, the user is prone to negative emotions such as irritability, and even affects the user's health, therefore, noise reduction processing needs to be performed on the outdoor unit.

[0105] S104: Control the outdoor unit to operate according to the target operating frequency.

[0106] After determining the target operating frequency currently required by the smart home appliance, the operating frequency of the smart home appliance is adjusted to the target operating frequency, and the outdoor unit of the smart home appliance is controlled to operate according to the target operating frequency, achieving the effect of noise reduction processing on the noise generated by the outdoor unit of the smart home appliance.

[0107] For example, if the target operating frequency is 35 Hz, the operating frequency of the outdoor unit of the smart home appliance is adjusted to 35 Hz, so that the operating frequency of the outdoor unit of the smart home appliance is finally maintained at 35 Hz.

[0108] The intelligent noise reduction control method provided in this embodiment obtains the first noise value and the current operating frequency of the outdoor unit of the smart home appliance. Based on the first noise value and the current operating frequency, it determines whether the outdoor unit is in a noisy state. When the outdoor unit is in a noisy state, it optimizes the current operating frequency of the outdoor unit, obtains the target operating frequency based on the optimization result, and controls the outdoor unit to operate at the target operating frequency. This method achieves intelligent noise reduction processing for smart home appliances, improves the working efficiency of smart home appliances, provides users with a suitable activity environment, and enhances the user experience.

[0109] Figure 2 The flowchart of the intelligent noise reduction control method provided in the embodiments of this application Figure 2 .like Figure 1 As shown, in this embodiment... Figure 3 Based on the embodiments, the intelligent noise reduction control method is described in detail. The intelligent noise reduction control method shown in this embodiment includes:

[0110] S201: Obtain candidate noise values ​​of the outdoor unit of smart home appliances according to a preset cycle.

[0111] S202: If the candidate noise values ​​obtained within a preset number of adjacent periods are the same, then the candidate noise value is taken as the first noise value of the outdoor unit.

[0112] Among them, the candidate noise value is used to indicate the decibel value detected by the noise detection device in real time, and the preset period can be, for example, 30 seconds.

[0113] A noise detection device installed at the outdoor unit of a smart home appliance acquires the detection results at a preset cycle, and uses these results as candidate noise values. If the preset number of candidate noise values ​​detected in adjacent cycles are the same, it indicates that the current operating frequency of the outdoor unit is stable, and the noise value detected by the noise detection device is also tending to be stable. In this case, the candidate noise value is taken as the first noise value of the outdoor unit.

[0114] For example, by using a noise sensor installed at the outdoor unit of a smart home appliance, the noise value detected by the noise sensor is acquired every 30 seconds, which is to say, a candidate noise value is acquired every 30 seconds. If the currently acquired candidate noise values ​​are 30 dB, 35 dB, 40 dB, 45 dB, 45 dB, and 45 dB, it means that the noise value detected by the noise sensor is approaching 45 dB. At this time, 45 dB is taken as the first noise value, and the outdoor unit is determined to need noise reduction treatment based on the first noise value.

[0115] S203: Obtain the current operating frequency of the outdoor unit.

[0116] After obtaining the noise value of the current outdoor unit as the first noise value, the running frequency corresponding to the first noise value is obtained, that is, the current running frequency of the outdoor unit.

[0117] For example, if the currently obtained first noise value is 45 decibels, the current running frequency of the outdoor unit corresponding to the noise value is 40 hertz.

[0118] S204: Determine the current running state of the outdoor unit according to the current running frequency and a plurality of preset frequency range.

[0119] Among them, the frequency range is used to indicate the frequency range corresponding to the different running modes of the outdoor unit of the smart home appliance under different external time states, and the running state is used to indicate the frequency range in which the current running frequency of the outdoor unit of the smart home appliance is located.

[0120] It can be understood that the running frequency of the outdoor unit of the smart home appliance corresponds to different frequency ranges under different external time states; when the smart home appliance obtains the first noise value, the frequency of the outdoor unit running is consistent with the current running frequency corresponding to the first noise value, and the current running frequency is stable in a certain frequency range; since different frequency ranges of the outdoor unit correspond to different use time periods and different running modes, the noise ranges corresponding to different frequency ranges are also different. For example, the noise value generated by the smart home appliance running in sleep mode at night is lower than the noise value generated by the smart home appliance running in standard mode during the day, and the acceptable noise range of the user during the day is higher than the acceptable noise range at night. In addition, when the running frequency of the outdoor unit of the smart home appliance is stable in any frequency range, the noise range selected by the smart home appliance when determining whether to perform noise reduction processing corresponds to the frequency range in which the current running frequency is stable.

[0121] Specifically, a plurality of preset frequency ranges can be pre-set according to the corresponding running frequency, noise value and corresponding frequency range of different models of smart home appliances in the historical running process, and the plurality of preset frequency ranges are, for example, low frequency range, medium frequency range and high frequency range; the low frequency range refers to the running frequency below 40 hertz, and the corresponding noise range is below 40 decibels; the medium frequency range refers to the running frequency between 41 hertz and 70 hertz, and the corresponding noise range is between 40 decibels and 70 decibels; the high frequency range refers to the running frequency above 70 hertz, and the corresponding noise range is above 70 decibels; wherein, the low frequency range corresponds to the user controlling the smart home appliance to run in sleep mode at night, the medium frequency range corresponds to the user controlling the smart home appliance to run in soft mode during the day, and the high frequency range corresponds to the user controlling the smart home appliance to run in standard cooling or heating mode during the day.

[0122] The current operating frequency is matched with a plurality of preset frequency ranges, and a preset frequency range where the operating frequency is located is determined, so that it is determined that the outdoor unit is in a current operating state corresponding to the currently determined preset frequency range.

[0123] Optionally, the determining of the current operating state of the outdoor unit according to the current operating frequency and the plurality of preset frequency ranges comprises:

[0124] It is judged whether the current operating frequency is in a first preset frequency range; if the current operating frequency is in the first preset frequency range, it is determined that the current operating state of the outdoor unit is a first operating state; if the current operating frequency is not in the first preset frequency range, it is judged whether the current operating frequency is in a second preset frequency range; when the current operating frequency is in the second preset frequency range, it is determined that the current operating state of the outdoor unit is a second operating state; when the current operating frequency is not in the second preset frequency range, it is determined that the current operating state of the outdoor unit is a third operating state.

[0125] The first preset frequency range is smaller than the second preset frequency range, and the first preset frequency range may be a low frequency range, and the second preset frequency range may be a medium frequency range; the first operating state is used to indicate that the operating frequency of the smart home appliance is in the first preset frequency range, the second operating state is used to indicate that the operating frequency of the smart home appliance is in the second preset frequency range, and the third operating state is used to indicate that the operating frequency of the smart home appliance is not in the first preset frequency range nor in the second preset frequency range, and the frequency range where the operating frequency corresponding to the third operating state is located may be a high frequency range.

[0126] The purpose of the step of judging whether the current operating frequency is in the first preset frequency range and whether the current operating frequency is in the second preset frequency range is to determine the preset frequency range where the operating frequency of the outdoor unit is currently located, so that the corresponding noise range can be obtained.

[0127] It can be understood that when the operating frequency of the smart home appliance is not in the first preset frequency range nor in the second preset frequency range, the range where the smart home appliance is currently located can be determined as a third preset frequency range. The operating frequency range of the smart home appliance is divided into the first preset frequency range, the second preset frequency range and the third preset frequency range in the embodiment, and the control method of the smart noise reduction is described in detail based on the division method. The division of the operating frequency range in the embodiment is not specially limited.

[0128] For example, the first preset frequency range is that the operating frequency is below 40 Hz, the second preset frequency range is that the operating frequency is between 41 Hz and 70 Hz, and the third preset frequency range is that the operating frequency is above 70 Hz; if the current operating frequency is 40 Hz, it indicates that the current operating frequency of the outdoor unit is in the first preset frequency range, and the current operating state of the outdoor unit is the first operating state; if the current operating frequency is 50 Hz, it indicates that the current operating frequency of the outdoor unit is in the second preset frequency range, and the current operating state of the outdoor unit is the second operating state; if the current operating frequency is 80 Hz, it indicates that the current operating frequency of the outdoor unit is in the third preset frequency range, and the current operating state of the outdoor unit is the third operating state.

[0129] S205: Determine the noise upper limit value corresponding to the current operating state according to the current operating state.

[0130] The noise upper limit value is used to indicate the maximum noise value corresponding to the preset frequency range.

[0131] According to the current operating state of the outdoor unit, the preset frequency range of the current operating frequency of the outdoor unit can be determined, and the corresponding noise upper limit value is obtained according to different preset frequency ranges, and the noise upper limit value corresponding to the current operating state is determined.

[0132] For example, if the current operating state is the first operating state, the corresponding operating frequency is in the first preset frequency range, and the noise upper limit value corresponding to the first operating state is 40 dB at this time; if the current operating state is the second operating state, the corresponding operating frequency is in the second preset frequency range, and the noise upper limit value corresponding to the second operating state is 60 dB at this time; if the current operating state is the third operating state, the corresponding operating frequency is in the third preset frequency range, and the noise upper limit value corresponding to the third operating state is 70 dB at this time.

[0133] Optionally, after determining the noise upper limit value corresponding to the current operating state according to the current operating state, the method further comprises:

[0134] Obtaining the noise upper limit value corresponding to the current operating state and the target noise upper limit value; determining whether the noise upper limit value and the target noise upper limit value are consistent; if not, controlling the intelligent household appliance to update the target noise upper limit value according to the noise upper limit value.

[0135] The target noise upper limit value is used to indicate the noise upper limit value used by the intelligent household appliance when it last determined whether the outdoor unit was in the noise state.

[0136] After determining the noise upper limit value for judging whether the outdoor unit of the current smart home appliance is in a noise state, it is judged whether the noise upper limit value is consistent with the target noise upper limit value. According to the judgment result, it can be determined whether the running frequency of the outdoor unit of the smart home appliance has changed greatly, that is, the running mode of the smart home appliance has changed, and the corresponding preset frequency range has also changed. When the noise upper limit value is consistent with the target noise upper limit value, the target noise upper limit value is still used to determine whether the outdoor unit is in a noise state. When the noise upper limit value is not consistent with the target noise upper limit value, the smart home appliance is controlled to update the target noise upper limit value according to the currently obtained noise upper limit value, so that the smart home appliance determines whether the outdoor unit is in a noise state according to the currently obtained noise upper limit value.

[0137] For example, the target noise upper limit value is 40 decibels. If the currently obtained noise upper limit value is 40 decibels, the target noise upper limit value does not need to be updated, the preset frequency range corresponding to the current running frequency does not change, and 40 decibels is still used as the noise upper limit value to determine whether the outdoor unit is in a noise state. If the currently obtained noise upper limit value is 60 decibels, it indicates that the preset frequency range corresponding to the current running frequency has changed, 60 decibels is selected to update the target noise upper limit value, and 60 decibels is used as the noise upper limit value to determine whether the outdoor unit is in a noise state.

[0138] S206: Determine whether the first noise value is greater than the noise upper limit value corresponding to the current running state.

[0139] The purpose of this step is to determine whether the current outdoor unit is in a noise state.

[0140] If the first noise value is greater than the noise upper limit value corresponding to the current running state, it indicates that the currently obtained noise value exceeds the maximum noise value corresponding to the current preset frequency range, and the user in the environment state of the first noise value is easy to produce negative emotions such as restlessness. At this time, it is determined that the outdoor unit is in a noise state, and the outdoor unit needs to be de-noised.

[0141] If the first noise value is not greater than the noise upper limit value corresponding to the current running state, it indicates that the currently obtained noise value does not exceed the maximum noise value corresponding to the current preset frequency range, and the noise generated by the current outdoor unit will not adversely affect the user. At this time, it is determined that the outdoor unit is not in a noise state, and the outdoor unit does not need to be de-noised, and the outdoor unit of the smart home appliance can be normally controlled.

[0142] For example, the upper limit value of the noise can be 40 decibels. If the first noise value is 45 decibels, which is greater than 40 decibels, it indicates that the noise will have a negative impact on the user's mood, at which time it is determined that the outdoor unit is in a noise state, and the outdoor unit needs to be processed for noise reduction. If the first noise value is 35 decibels, which is less than 40 decibels, it indicates that the noise will not have a negative impact on the user's mood, at which time it is determined that the outdoor unit is not in a noise state, and the outdoor unit does not need to be processed for noise reduction, and the outdoor unit of the intelligent household appliance is controlled to operate normally.

[0143] S207: When the first noise value is greater than the upper limit value of the noise corresponding to the current operating state, it is determined that the outdoor unit is in a noise state.

[0144] S208: When the outdoor unit is in a noise state, the current operating frequency of the outdoor unit is processed for frequency reduction and frequency increase at a first preset rate.

[0145] S209: Obtain a second noise value corresponding to a plurality of first candidate operating frequencies in a frequency range corresponding to the current operating state.

[0146] For example, the first preset rate can be 1 hertz per 10 seconds, and the number of continuous reductions or increases is 5 times. The first candidate operating frequency is used to indicate the operating frequency of the intelligent household appliance after frequency increase or frequency reduction at the first preset rate. The second noise value is used to indicate the noise value generated by the outdoor unit when the intelligent household appliance operates at the first candidate operating frequency.

[0147] When it is determined that the outdoor unit is in a noise state, the current operating frequency of the outdoor unit is processed for frequency reduction and frequency increase at a first preset rate. Since the noise detection device can detect the noise generated by the outdoor unit in real time, the noise value generated by the outdoor unit after frequency reduction or frequency increase can be detected in real time when the current operating frequency of the outdoor unit is processed for frequency reduction and frequency increase.

[0148] For example, if the currently obtained first noise value is 45 decibels, and the current operating frequency of the outdoor unit corresponding to the noise value is 40 hertz, then the frequency reduction processing is performed 5 times at a rate of 1 hertz per 10 seconds, and the frequency increase processing is performed 5 times at a rate of 1 hertz per 10 seconds. At this time, the plurality of first candidate operating frequencies obtained are: 35 hertz, 36 hertz, 37 hertz, 38 hertz, 39 hertz, 41 hertz, 42 hertz, 43 hertz, 44 hertz, and 45 hertz, and the plurality of second noise values corresponding to the plurality of first candidate operating frequencies are: 35 decibels, 38 decibels, 40 decibels, 41 decibels, 41 decibels, 45 decibels, 46 decibels, 47 decibels, 48 decibels, and 49 decibels.

[0149] S210: determining the target operating frequency according to the plurality of second noise values.

[0150] After the current operating frequency of the outdoor unit is subjected to the frequency reduction processing and the frequency increase processing, a plurality of first candidate operating frequencies can be determined according to the results of the frequency reduction processing and the frequency increase processing; a plurality of second noise values corresponding to the plurality of first candidate operating frequencies can be detected by the noise detection device, the minimum noise value is selected from the plurality of second noise values, the first candidate operating frequency corresponding to the minimum noise value is obtained, and the operating frequency is determined as the target operating frequency.

[0151] For example, after the current operating frequency of the outdoor unit is subjected to the frequency reduction processing and the frequency increase processing, the plurality of first candidate operating frequencies obtained are 35 Hz, 36 Hz, 37 Hz, 38 Hz, 39 Hz, 41 Hz, 42 Hz, 43 Hz, 44 Hz, and 45 Hz, respectively, and the plurality of second noise values corresponding to the plurality of first candidate operating frequencies are 35 dB, 38 dB, 40 dB, 41 dB, 41 dB, 45 dB, 46 dB, 47 dB, 48 dB, and 49 dB, respectively; wherein the minimum noise value in the plurality of second noise values is 35 dB, and the corresponding first candidate operating frequency is 35 Hz, and the target operating frequency of the outdoor unit is determined as 35 Hz.

[0152] S211: controlling the outdoor unit to operate at the target operating frequency.

[0153] After the target operating frequency currently required by the smart home appliance is determined, the current operating frequency of the smart home appliance is adjusted to the target operating frequency, and at this time, the outdoor unit of the smart home appliance is controlled to operate at the target operating frequency, thereby achieving the effect of noise reduction processing on the noise generated by the outdoor unit of the smart home appliance.

[0154] Optionally, when the current operating state is the second operating state or the third operating state, after the outdoor unit is controlled to operate at the target operating frequency, the method further comprises:

[0155] obtaining a third noise value generated when the outdoor unit operates at the target operating frequency; determining whether the third noise value is greater than the noise upper limit value corresponding to the current operating state; when the third noise value is greater than the noise upper limit value corresponding to the current operating state, performing frequency reduction processing and frequency increase processing on the current operating frequency of the outdoor unit at a second preset rate, and obtaining a fourth noise value corresponding to a plurality of second candidate operating frequencies within a frequency range corresponding to the current operating state; determining a new target operating frequency according to the plurality of fourth noise values; and controlling the outdoor unit to operate at the new target operating frequency.

[0156] The third noise value is used to indicate the noise value detected by the noise detection device when the smart home appliance is running at the target running frequency; the second preset rate is greater than the first preset rate, for example, the second preset rate can be 1 Hz reduction or increase per 10 seconds, and the number of continuous reductions or increases is 10 times; the second candidate running frequency is used to indicate the running frequency of the smart home appliance after frequency increasing processing and frequency decreasing processing according to the second preset rate, and the fourth noise value is used to indicate the noise value generated by the outdoor unit when the smart home appliance is running at the second candidate running frequency; and the new target running frequency is the second candidate running frequency with the minimum fourth noise value in the plurality of second candidate running frequencies.

[0157] After the outdoor unit is controlled to run at the target running frequency in the current running state being the second running state or the third running state, a third noise value generated by the outdoor unit when running at the target running frequency is obtained, and it is determined whether the currently obtained third noise value is greater than the noise upper limit value corresponding to the current running state; if the third noise value is greater than the noise upper limit value corresponding to the current running state, it indicates that the previous noise reduction processing of the smart home appliance does not achieve the preset effect, that is, the noise value of the outdoor unit is reduced below the corresponding noise upper limit value, at this time, the current running frequency of the outdoor unit is processed according to the second preset rate to obtain a plurality of second candidate running frequencies; and through the noise detection device, the corresponding noise value generated by the outdoor unit when running at the plurality of second candidate running frequencies is detected in real time, that is, the fourth noise values corresponding to the plurality of second candidate running frequencies in the frequency range corresponding to the current running state are obtained; according to the plurality of fourth noise values, the minimum noise value is selected, the second candidate running frequency corresponding to the minimum noise value is obtained, and the second candidate running frequency is determined as the new target running frequency; and the outdoor unit is controlled to run at the new target running frequency.

[0158] For example, when the current running state is the second running state, the target running frequency is 60 Hz, and the upper limit of noise is 60 decibels, the third noise value generated by the outdoor unit running according to the target running frequency is 61 decibels, and 61 decibels is greater than 60 decibels, then the frequency reduction processing is performed on it 10 times according to 1 Hz reduction every 10 seconds, and the frequency increase processing is performed on it 10 times according to 1 Hz increase every 10 seconds; At this time, the plurality of second candidate running frequencies obtained are: 50 Hz, 51 Hz, 52 Hz, 53 Hz, 54 Hz, 55 Hz, 56 Hz, 57 Hz, 58 Hz, 59 Hz, 61 Hz, 62 Hz, 63 Hz, 64 Hz, 65 Hz, 66 Hz, 67 Hz, 68 Hz, 69 Hz, and 70 Hz, and the plurality of fourth noise values corresponding to the plurality of second candidate running frequencies are: 50 decibels, 51 decibels, 52 decibels, 52 decibels, 53 decibels, 54 decibels, 55 decibels, 56 decibels, 57 decibels, 59 decibels, 62 decibels, 62 decibels, 63 decibels, 64 decibels, 65 decibels, 66 decibels, 67 decibels, 68 decibels, 69 decibels, and 70 decibels; Among them, the minimum noise value in the plurality of fourth noise values is 50 decibels, and the corresponding second candidate running frequency is 50 Hz, at this time, the target running frequency of the outdoor unit is determined as 50 Hz, and the intelligent household appliance is controlled to run at 50 Hz.

[0159] The intelligent noise reduction control method provided in the embodiment, by acquiring the candidate noise value of the outdoor unit of the intelligent household appliance according to the preset period, if the candidate noise values acquired in the preset number of adjacent periods are the same, the current acquired candidate noise value is taken as the first noise value of the outdoor unit; the current running frequency of the outdoor unit is acquired, and the current running state of the outdoor unit is determined according to the current running frequency and the plurality of preset frequency range; according to the current running state, the frequency range in which the current running frequency of the outdoor unit is located is determined, and the upper limit of noise corresponding to the frequency range is determined; it is judged whether the first noise value is greater than the currently determined upper limit of noise, when the first noise value is greater than the upper limit of noise, it can be determined that the outdoor unit is in the noise state; when the outdoor unit is in the noise state, the current running frequency of the outdoor unit is reduced and increased according to the first preset rate, and the second noise value corresponding to the plurality of first candidate running frequencies in the frequency range corresponding to the current running state is acquired, and then the target running frequency is determined, and the outdoor unit is controlled to run according to the target running frequency.
