[0083] With the continuous development of science and technology, the functions of smart home appliances are constantly being updated. In order to meet people's ever-increasing living needs, various smart home appliances are constantly being introduced.

[0084] Smart air conditioners are air conditioners with automatic adjustment functions. Based on external climate conditions and pre-set indicators, these systems analyze and assess signals from temperature, humidity, and air cleanliness sensors installed in the space where the smart air conditioner is located, automatically activating cooling, heating, dehumidification, and air purification functions. By autonomously adjusting the operating mode of the smart air conditioner, the temperature in the space where the smart air conditioner is installed remains constant, providing a better user environment.

[0085] However, with the diverse range of air conditioners available both domestically and internationally, and their widespread use, various market issues continue to arise. Air conditioner noise remains a major headache. Air conditioner noise is the noise emitted by intelligent air conditioning systems during operation, including fan noise that escapes into the room and regenerative noise at the end of the air duct. Fan noise is a combination of modulated noise generated by rotating blades striking the surrounding air and irregular noise caused by eddy currents. Existing technologies often employ fixed noise reduction schemes to address this noise. However, since the acceptable noise range for intelligent air conditioners varies depending on the time of day, existing technologies are unable to intelligently reduce noise based on the current time of day.

[0086] In response to the above problems, the present application provides an intelligent noise reduction control method.

[0087] First, the implementation scenarios involved in this application are described.

[0088] With the widespread use of smart home appliances, smart air conditioners are mostly installed in spaces where users frequently move around, such as bedrooms, to provide users with a better user experience. To better meet user needs, smart home appliances are equipped with various detection devices that can achieve real-time noise detection of the environment in which the smart home appliances are located. Based on different detection results, different processing solutions are adopted, making the noise reduction control of smart home appliances more intelligent. The smart home appliances involved in this application can, for example, be smart home appliances equipped with noise detection devices.

[0089] Smart home appliances are usually installed in locations that are convenient for users to use. For example, smart air conditioners are usually installed indoors to bring fresh air from outdoors into the room. During the use of smart air conditioners, the noise generated by smart air conditioners also changes with the change of usage time. By installing a noise detection device on the outdoor unit of the smart air conditioner, the noise value generated by the outdoor unit is detected in real time, and combined with the time status of the smart air conditioner when it is currently in use, a suitable noise reduction solution is selected to reduce the noise of the outdoor unit of the current smart home appliance, thereby realizing intelligent noise reduction of the outdoor unit.

[0090] The intelligent noise reduction control method provided by this application determines the current operating frequency band of the smart home appliance and obtains 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; after the detection result meets the noise reduction condition, the operating frequency of the outdoor unit that triggers the noise reduction condition is reduced or increased; based on the results of the frequency reduction and increase processing, the operating frequency corresponding to the minimum noise value generated is determined as the target operating frequency of the current outdoor unit, and the outdoor unit of the smart home appliance is controlled to operate at the target operating frequency. This method realizes intelligent noise reduction processing of smart home appliances, improves the working efficiency of smart home appliances, realizes frequency band noise reduction for different operating environments, provides users with a suitable activity environment, and improves the user experience.

[0091] 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.

[0092] FIG1 is a flowchart of the first embodiment of the intelligent noise reduction control method provided by the present application. The execution subject of this embodiment may be, for example, a control device of a smart home appliance. As shown in FIG1 , the intelligent noise reduction control method provided by this embodiment includes:

[0093] S101: Acquire a first noise value of an outdoor unit of a smart home appliance and a current operating frequency of the outdoor unit.

[0094] 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 times the compressor of the smart home appliance rotates per second.

[0095] It can be understood that a noise detection device is provided at the outdoor unit of the smart home appliance, which is used to detect the noise generated by the outdoor unit in real time; according to the setting position of the noise detection device at 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.

[0096] By setting up a noise detection device on the outdoor unit of the smart home appliance, the noise generated by the current outdoor unit is detected in real time; according to the results of the real-time detection, the currently obtained noise value is used as the first noise value, and the operating frequency of the outdoor unit of the smart home appliance is obtained when the noise value generated by the outdoor unit is the first noise value.

[0097] For example, the noise detection device installed in the outdoor unit of a smart home appliance can be a noise sensor, which detects the noise conditions at the outdoor unit 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 Hz.

[0098] S102: Determine whether the outdoor unit is in a noise state according to the first noise value and the current operating frequency.

[0099] The noise status indicates that the noise currently generated by the smart home appliance will interfere with the user's normal activities and rest.

[0100] It is understandable that when using smart home appliances, the operating mode of the smart home appliances is adjusted according to different user needs. Most users will select different operating modes according to different time periods, and smart home appliances will select different operating frequencies according to different operating modes. Users have different acceptable noise value ranges under different external time conditions. Therefore, it can be determined that smart home appliances have different noise ranges corresponding to different operating frequencies for determining whether the current outdoor unit is in a noisy state. Based on the currently obtained first noise value and the current operating frequency, the relationship between the first noise value and the corresponding noise range is determined, thereby determining whether the outdoor unit is in a noisy state and whether the outdoor unit requires noise reduction processing.

[0101] According to the currently obtained 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 conforms to the current operating frequency range can be obtained; it is judged whether the currently obtained first noise value is within the noise range, that is, whether the user can accept the smart home appliance running at the current frequency, and whether the noise generated by the outdoor unit is within the user's acceptable noise range; 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 user's acceptable noise range. At this time, it can be determined that the outdoor unit is in a noisy state, and the current outdoor unit needs to be noise reduced.

[0102] For example, 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 Hz, and the current operating frequency of the outdoor unit is in the low frequency band, the corresponding noise range is below 40 decibels, and 45 decibels is greater than 40 decibels, then it indicates that the noise generated by the outdoor unit is not within the user's acceptable noise range. At this time, it can be determined that the user is in a noisy 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 physical health. Therefore, the outdoor unit needs to be noise-reduced.

[0103] S103: When the outdoor unit is in a noisy state, optimizing the current operating frequency of the outdoor unit to obtain a target operating frequency.

[0104] The target operating frequency is used to indicate the outdoor unit frequency selected when performing noise reduction processing on the noise generated by the outdoor unit of the smart home appliance.

[0105] When it is determined that the noise generated by the current outdoor unit causes the current user to be in a noisy state, the current operating frequency of the outdoor unit is optimized; based on 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.

[0106] For example, when the outdoor unit is in a noisy state, 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 Hz, and the current operating frequency of the outdoor unit is in the low frequency band, and the corresponding noise range is below 40 decibels. The current operating frequency is optimized, and the optimization results obtained are: "38 Hz, 41 decibels", "36 Hz, 40 decibels", "35 Hz, 35 decibels". It can be obtained that the minimum noise value generated by the outdoor unit is 35 decibels, and the corresponding operating frequency is 35 Hz. At this time, the target operating frequency is 35 Hz.

[0107] S104: Control the outdoor unit to operate according to the target operating frequency.

[0108] After determining the target operating frequency that the smart home appliance currently needs to run, the current 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, so as to achieve the effect of noise reduction of the noise generated by the outdoor unit of the smart home appliance.

[0109] For example, if the target operating frequency is 35 Hz, the outdoor unit of the smart home appliance is controlled to adjust the operating frequency with the 35 Hz target, so that the operating frequency of the outdoor unit of the smart home appliance is finally maintained at 35 Hz.

[0110] The intelligent noise reduction control method provided in this embodiment obtains a first noise value and the current operating frequency of the outdoor unit of a smart home appliance. Based on the first noise value and the current operating frequency, the method determines whether the outdoor unit is in a noisy state. If the outdoor unit is in a noisy state, the method optimizes the current operating frequency of the outdoor unit, obtains a target operating frequency based on the optimization results, and controls the outdoor unit to operate at the target operating frequency. This method implements intelligent noise reduction for smart appliances, improves their operating efficiency, provides users with a suitable activity environment, and enhances their user experience.

[0111] FIG2 is a flowchart of the second embodiment of the intelligent noise reduction control method provided by the embodiment of the present application. As shown in FIG2, this embodiment provides a detailed description of the intelligent noise reduction control method based on the embodiment of FIG1. ​​The intelligent noise reduction control method shown in this embodiment includes:

[0112] S201: Acquire candidate noise values ​​of the outdoor unit of the smart home appliance according to a preset period.

[0113] S202: If the candidate noise values ​​obtained within a preset number of adjacent cycles are the same, the candidate noise value is used as the first noise value of the outdoor unit.

[0114] The candidate noise value is used to indicate the decibel value detected in real time by the noise detection device, and the preset period may be, for example, 30 seconds.

[0115] A noise detection device installed at the outdoor unit of the smart home appliance obtains detection results from the noise detection device at a preset period and uses the detection results as candidate noise values. If a preset number of candidate noise values ​​detected in consecutive periods 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 used as the first noise value of the outdoor unit.

[0116] For example, a noise sensor is set at the outdoor unit of a smart home appliance, and the noise value detected by the noise sensor is obtained every 30 seconds, that is, a candidate noise value is obtained every 30 seconds; if the currently obtained candidate noise values ​​are: 30 decibels, 35 decibels, 40 decibels, 45 decibels, 45 decibels, 45 decibels, it indicates that the noise value detected by the noise sensor at this time tends to 45 decibels. At this time, 45 decibels is used as the first noise value, and whether the outdoor unit needs to perform noise reduction processing is determined based on the first noise value.

[0117] S203: Acquire the current operating frequency of the outdoor unit.

[0118] After the current noise value of the outdoor unit is acquired as the first noise value, the operating frequency corresponding to the first noise value is acquired, which is the current operating frequency of the outdoor unit.

[0119] 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.

[0120] S204: Determine the current operating state of the outdoor unit according to the current operating frequency and a plurality of preset frequency bands.

[0121] Among them, the frequency band range is used to indicate the corresponding frequency range when the outdoor unit of the smart home appliance operates in different operating modes under different external time conditions, and the operating status is used to indicate the frequency band range of the current operating frequency of the outdoor unit of the smart home appliance.

[0122] It is understandable that the operating frequency of the outdoor unit of the smart home appliance corresponds to different frequency bands under different external time conditions; when the smart home appliance obtains the first noise value, the operating frequency of the outdoor unit is consistent with the current operating frequency corresponding to the first noise value, and the current operating frequency is stable within a certain frequency band; since different frequency bands of the outdoor unit correspond to different usage time periods and different operating modes, the noise ranges corresponding to different frequency bands are also different. For example, the noise value generated by the smart home appliance running in sleep mode when the user is resting at night is lower than the noise value generated by the smart home appliance running in standard mode when the user is working during the day, and the noise range acceptable to the user during the day is also higher than the noise range acceptable to the user at night. In addition, when the operating frequency of the outdoor unit of the smart home appliance is stable in any frequency band, the noise range selected by the smart home appliance when determining whether to perform noise reduction processing corresponds to the frequency band range in which the current operating frequency is stable.

[0123] Specifically, multiple preset frequency bands can be pre-set according to the corresponding operating frequencies, noise values ​​and corresponding frequency bands of different models of smart home appliances in the historical operation process. The multiple preset frequency bands are, for example, low frequency band, medium frequency band and high frequency band; the low frequency band refers to the operating frequency below 40 Hz, and the corresponding noise range is below 40 decibels; the medium frequency band refers to the operating frequency between 41 Hz and 70 Hz, and the corresponding noise range is between 40 decibels and 70 decibels; the high frequency band refers to the operating frequency above 70 Hz, and the corresponding noise range is above 70 decibels; among them, the low frequency band corresponds to the user controlling the smart home appliances to run the sleep mode when resting at night, the medium frequency band corresponds to the user controlling the smart home appliances to run the gentle mode during leisure time during the day, and the high frequency band corresponds to the user controlling the smart home appliances to run the standard cooling or heating mode when working during the day.

[0124] The current operating frequency is matched with a plurality of preset frequency bands to determine the preset frequency band in which the operating frequency is located, thereby determining that the outdoor unit is in a current operating state corresponding to the currently determined preset frequency band.

[0125] Optionally, determining the current operating state of the outdoor unit according to the current operating frequency and a plurality of preset frequency bands includes:

[0126] Determine whether the current operating frequency is within the first preset frequency band; if the current operating frequency is within the first preset frequency band, determine that the current operating state of the outdoor unit is the first operating state; if the current operating frequency is not within the first preset frequency band, determine whether the current operating frequency is within the second preset frequency band; when the current operating frequency is within the second preset frequency band, determine that the current operating state of the outdoor unit is the second operating state; when the current operating frequency is not within the second preset frequency band, determine that the current operating state of the outdoor unit is the third operating state.

[0127] Among them, the first preset frequency band range is smaller than the second preset frequency band range, the first preset frequency band range can be, for example, a low frequency band range, and the second preset frequency band range can be, for example, a medium frequency band range; the first operating state is used to indicate that the operating frequency of the smart home appliance is within the first preset frequency band range, the second operating state is used to indicate that the operating frequency of the smart home appliance is within the second preset frequency band range, and the third operating state is used to indicate that the operating frequency of the smart home appliance is neither within the first preset frequency band range nor within the second preset frequency band range. At this time, the frequency band range of the operating frequency corresponding to the third operating state can be, for example, a high frequency band range.

[0128] The purpose of judging whether the current operating frequency is within the first preset frequency band and whether the current operating frequency is within the second preset frequency band in this step is to determine the preset frequency band in which the operating frequency of the outdoor unit is currently located, so as to obtain the corresponding noise range.

[0129] It is understandable that when the operating frequency of the smart home appliance is neither within the first preset frequency band nor within the second preset frequency band, the current range of the smart home appliance can be determined as the third preset frequency band. This embodiment divides the operating frequency range of the smart home appliance into the first preset frequency band, the second preset frequency band, and the third preset frequency band, and describes in detail the control method for intelligent noise reduction based on this division. This embodiment does not impose any special restrictions on the division of the operating frequency range.

[0130] For example, the first preset frequency band range is an operating frequency below 40 Hz, the second preset frequency band range is an operating frequency between 41 Hz and 70 Hz, and the third preset frequency band range is an operating frequency 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 band 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 band 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 band range, and the current operating state of the outdoor unit is the third operating state.

[0131] S205: Determine a noise upper limit value corresponding to the current operating state according to the current operating state.

[0132] The upper noise limit value is used to indicate the maximum noise value corresponding to the preset frequency band range.

[0133] According to the current operating state of the outdoor unit, the preset frequency band range of the outdoor unit's current operating frequency can be determined. According to different preset frequency band ranges, the corresponding noise upper limit value is obtained, from which the noise upper limit value corresponding to the current operating state is determined.

[0134] For example, if the current operating state is the first operating state, the corresponding operating frequency is within the first preset frequency band, and the noise upper limit value corresponding to the first operating state is 40 decibels; if the current operating state is the second operating state, the corresponding operating frequency is within the second preset frequency band, and the noise upper limit value corresponding to the second operating state is 60 decibels; if the current operating state is the third operating state, the corresponding operating frequency is within the third preset frequency band, and the noise upper limit value corresponding to the third operating state is 70 decibels.

[0135] Optionally, after determining the noise upper limit corresponding to the current operating state according to the current operating state, the method further includes:

[0136] Obtain the noise upper limit value and the target noise upper limit value corresponding to the current operating state; determine whether the noise upper limit value is consistent with the target noise upper limit value; if not, control the smart home appliance to update the target noise upper limit value according to the noise upper limit value.

[0137] The target noise upper limit value is used to indicate the noise upper limit value used by the smart home appliance when it last determined whether the outdoor unit was in a noise state.

[0138] After determining the noise upper limit value used by the outdoor unit of the current smart home appliance when judging whether the outdoor unit 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 operating frequency of the outdoor unit of the smart home appliance has changed significantly, that is, the operating mode of the smart home appliance has changed, and the corresponding preset frequency band range has also changed accordingly; 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 judge whether the outdoor unit is in a noise state; when the noise upper limit value is inconsistent 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 with the currently obtained noise upper limit value.

[0139] 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 band range corresponding to the current operating frequency has not changed, and 40 decibels is still used as the noise upper limit value to determine whether the outdoor unit is in a noisy state; if the currently obtained noise upper limit value is 60 decibels, it indicates that the preset frequency band range corresponding to the current operating frequency has changed, and 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 noisy state.

[0140] S206: Determine whether the first noise value is greater than the noise upper limit value corresponding to the current operating state.

[0141] The purpose of judging whether the first noise value is greater than the upper limit of noise corresponding to the current operating state in this step is to determine whether the outdoor unit is currently in a noisy state.

[0142] If the first noise value is greater than the noise upper limit value corresponding to the current operating state, it indicates that the currently obtained noise value exceeds the maximum noise value corresponding to the current preset frequency band range. The user is prone to negative emotions such as irritability in the environment of the first noise value. At this time, it is determined that the outdoor unit is in a noisy state and the outdoor unit needs to be noise-reduced.

[0143] If the first noise value is not greater than the noise upper limit value corresponding to the current operating state, it indicates that the currently obtained noise value does not exceed the maximum noise value corresponding to the current preset frequency band range, and the noise generated by the current outdoor unit will not have an adverse effect on 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 subjected to noise reduction processing. The outdoor unit of the smart home appliance can be controlled to operate normally.

[0144] For example, the noise upper limit value can be 40 decibels. If the first noise value is 45 decibels and 45 decibels is greater than 40 decibels, it indicates that the noise will have a negative impact on the user's mood. At this time, it is determined that the outdoor unit is in a noisy state, and the outdoor unit needs to be processed for noise reduction; if the first noise value is 35 decibels and 35 decibels is less than 40 decibels, it indicates that the noise will not have a negative impact on the user's mood. At this time, it is determined that the outdoor unit is not in a noisy state, and the outdoor unit does not need to be processed for noise reduction, and the outdoor unit of the smart home appliance is controlled to operate normally.

[0145] S207: When the first noise value is greater than the noise upper limit corresponding to the current operating state, determine that the outdoor unit is in a noise state.

[0146] S208: When the outdoor unit is in a noise state, performing frequency reduction and frequency increase processing on the current operating frequency of the outdoor unit according to a first preset rate.

[0147] S209: Acquire second noise values ​​corresponding to a plurality of first candidate operating frequencies within a frequency band corresponding to the current operating state.

[0148] Among them, the first preset rate can be, for example, a decrease or increase of 1 Hz every 10 seconds, and the number of consecutive decreases or increases is 5 times; the first candidate operating frequency is used to indicate the operating frequency of the smart home appliance after up-frequency processing or down-frequency processing according to the first preset rate; the second noise value is used to indicate the noise value generated by the outdoor unit when the smart home appliance operates at the first candidate operating frequency.

[0149] When it is determined that the outdoor unit is in a noise state, the current operating frequency of the outdoor unit is processed by down-conversion and up-conversion according to a first preset rate; since the noise detection device can detect the noise generated by the outdoor unit in real time, when the current operating frequency of the outdoor unit is processed by down-conversion and up-conversion, the noise value generated by the outdoor unit after the frequency reduction or increase can be detected in real time.

[0150] For example, if the first noise value currently obtained is 45 decibels, and the current operating frequency of the outdoor unit corresponding to the noise value is 40 Hz, the frequency is reduced by 1 Hz for 5 times every 10 seconds, and the frequency is increased by 1 Hz for 5 times every 10 seconds; at this time, the multiple 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, and the multiple second noise values ​​corresponding to the multiple 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.

[0151] S210: Determine the target operating frequency according to the plurality of second noise values.

[0152] After the current operating frequency of the outdoor unit is down-processed and up-processed, multiple first candidate operating frequencies can be determined based on the results of the down-processing and up-processing; multiple second noise values ​​corresponding to the multiple first candidate operating frequencies can be detected by the noise detection device, the minimum noise value can be screened out, and the first candidate operating frequency corresponding to the minimum noise value is obtained, and the operating frequency is determined as the target operating frequency.

[0153] For example, after down-conversion and up-conversion processing are performed on the current operating frequency of the outdoor unit, the multiple 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, and the multiple second noise values ​​corresponding to the multiple 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; among them, the minimum noise value among the multiple second noise values ​​is 35 decibels, and the corresponding first candidate operating frequency is 35 Hz. At this time, the target operating frequency of the outdoor unit is determined to be 35 Hz.

[0154] S211: Control the outdoor unit to operate according to the target operating frequency.

[0155] After determining the target operating frequency that the smart home appliance currently needs to run, the current operating frequency of the smart home appliance is adjusted to the target operating frequency. At this time, the outdoor unit of the smart home appliance is controlled to operate according to the target operating frequency, thereby achieving the effect of noise reduction of the noise generated by the outdoor unit of the smart home appliance.

[0156] Optionally, when the current operating state is the second operating state or the third operating state, after controlling the outdoor unit to operate according to the target operating frequency, the method further includes:

[0157] Obtain a third noise value generated when the outdoor unit operates at a target operating frequency; determine whether the third noise value is greater than a 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, perform frequency reduction and frequency increase processing on the current operating frequency of the outdoor unit according to a second preset rate, and obtain fourth noise values ​​corresponding to multiple second candidate operating frequencies within a frequency band corresponding to the current operating state; determine a new target operating frequency based on the multiple fourth noise values; and control the outdoor unit to operate at the new target operating frequency.

[0158] Among them, the third noise value is used to indicate the noise value detected by the noise detection device when the smart home appliance is operating at the target operating frequency; the second preset rate is greater than the first preset rate, and the second preset rate can be, for example, reduced or increased by 1 Hz every 10 seconds, and the number of consecutive reductions or increases is 10 times; the second candidate operating frequency is used to indicate the operating frequency of the smart home appliance after up-frequency processing and down-frequency 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 operating at the second candidate operating frequency; the new target operating frequency is the second candidate operating frequency with the smallest fourth noise value among multiple second candidate operating frequencies.

[0159] When the current operating state is the second operating state or the third operating state and the outdoor unit is controlled to operate at a target operating frequency, a third noise value generated by the outdoor unit when operating at the target operating frequency is obtained, and it is determined whether the currently obtained third noise value is greater than a noise upper limit value corresponding to the current operating state. If the third noise value is greater than the noise upper limit value corresponding to the current operating state, it indicates that the noise reduction processing previously performed by the smart home appliance did not achieve a preset effect, and the noise value of the outdoor unit is reduced to below the corresponding noise upper limit value. At this time, the current operating frequency of the outdoor unit is down-converted and up-converted at a second preset rate to obtain a plurality of second candidate operating frequencies. When the outdoor unit operates at the plurality of second candidate operating frequencies, corresponding noise values ​​generated by the outdoor unit are detected in real time by a noise detection device, so as to obtain fourth noise values ​​corresponding to the plurality of second candidate operating frequencies within a frequency band corresponding to the current operating state. A minimum noise value is screened out from the plurality of fourth noise values, a second candidate operating frequency corresponding to the minimum noise value is obtained, and the second candidate operating frequency is determined as a new target operating frequency. The outdoor unit is controlled to operate at the new target operating frequency.

[0160] For example, when the current operating state is the second operating state, the target operating frequency is 60 Hz, and the noise upper limit is 60 decibels, the third noise value generated by the outdoor unit when operating at the target operating frequency is 61 decibels. Since 61 decibels is greater than 60 decibels, the frequency is reduced by 1 Hz every 10 seconds for 10 times, and the frequency is increased by 1 Hz every 10 seconds for 10 times. At this time, the multiple second candidate operating 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, 70 Hz, 71 Hz, 72 Hz, 73 Hz, 74 Hz, 75 Hz, 76 Hz, 77 Hz, 78 Hz, 79 Hz, 80 Hz, 81 Hz, 82 Hz, 83 Hz, 84 Hz, 85 Hz, 86 Hz, 87 Hz, 88 Hz, 89 Hz, 90 Hz, 91 Hz, 92 Hz, 93 Hz, 94 Hz, 95 Hz, 96 Hz, 97 Hz, 98 5 Hz, 66 Hz, 67 Hz, 68 Hz, 69 Hz, and 70 Hz, and the multiple fourth noise values ​​corresponding to the multiple second candidate operating 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 among the multiple fourth noise values ​​is 50 decibels, and the corresponding second candidate operating frequency is 50 Hz. At this time, the target operating frequency of the outdoor unit is determined to be 50 Hz, and the smart home appliances are controlled to operate at 50 Hz.

[0161] The intelligent noise reduction control method provided in this embodiment obtains candidate noise values ​​of the outdoor unit of the smart home appliance according to a preset period. If the candidate noise values ​​obtained within a preset number of adjacent periods are the same, the currently obtained candidate noise value is used as the first noise value of the outdoor unit; obtains the current operating frequency of the outdoor unit, and determines the current operating state of the outdoor unit based on the current operating frequency and multiple preset frequency bands; determines the frequency band range in which the current operating frequency of the outdoor unit is located according to the current operating state, and determines the noise upper limit value corresponding to the frequency band range; determines whether the first noise value is greater than the currently determined noise upper limit value. When the first noise value is greater than the noise upper limit value, it can be determined that the outdoor unit is in a noise state; when the outdoor unit is in the noise state, the current operating frequency of the outdoor unit is down-converted and up-converted according to a first preset rate, and obtains second noise values ​​corresponding to multiple first candidate operating frequencies within the frequency band range corresponding to the current operating state, and then determines a target operating frequency therefrom, and controls the outdoor unit to operate according to the target operating frequency. This method realizes intelligent noise reduction processing of smart home appliances, improves the working efficiency of smart home appliances, realizes frequency band noise reduction for different operating environments, provides users with a suitable activity environment, and improves the user experience.
