[0054] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0055] Example 1

[0056] In the prior art, light sensors and sound sensors are used to determine the environment in which the refrigerator is located, and the refrigerator enters a silent operation mode according to different light brightness and noise conditions, so that the compressor and fan can run at a low speed to reduce the noise of the refrigerator. However, strong light may be caused by the user forgetting to turn off the light before going to bed, and the light level cannot truly reflect the user's activity level. Therefore, it is not accurate to control the speed of the compressor and fan according to the light level.

[0057] In view of the problem that the speed of the compressor and the fan is controlled according to the light level when the refrigerator is running in the prior art, but the accuracy is poor, this embodiment provides a noise control method. Figure 1 is a flow chart of a noise control method according to an embodiment of the present invention. Figure 1 As shown, the noise control method includes:

[0058] S101, obtaining a current time period and an environmental noise value; wherein the current time period includes an active time period, a leisure time period, and a sleeping time period.

[0059] Refrigerator controller timing. In order to ensure the accuracy and effectiveness of the refrigerator controller timing, the user needs to initialize and set the refrigerator time through the refrigerator display panel according to the current actual time after the refrigerator is powered on, in accordance with the requirements of the refrigerator manual. After that, the refrigerator timing will work normally.

[0060] S102, controlling the speed level of the compressor and the fan in the refrigerator according to the current time period and the ambient noise value.

[0061] The current time period can accurately reflect the user's work and rest state. For example, a day can be divided into three time periods: 8:00-18:00 is the user's active time period, 18:00-21:00 is the user's leisure time period, and 21:00-8:00 is the user's sleep time period. According to life experience, the higher the user's activity level, the lower the noise requirement, and the lower the user's activity level, the higher the noise requirement. Therefore, the active time period has the lowest noise requirement, while the sleep time period has the highest noise requirement. In addition, since people's work and rest states are not static, it is also possible that after the user's sleep time period is reached on a certain day, the user's activities are still relatively active, and the user's activities will cause noise in the environment. That is to say, the environmental noise value can also reflect the user's activity level to a certain extent. Therefore, combined with the current time period and the environmental noise value, the user's activity level can be judged more accurately. Controlling the speed gear of the compressor and the fan in the refrigerator according to the current time period and the environmental noise value can better meet the user's noise requirements.

[0062] The noise control method of this embodiment first obtains the current time period and the ambient noise value, determines whether the current time period is an active time period, a leisure time period, or a sleeping time period, accurately determines the user's activity level based on the current time period and the ambient noise, and then determines the user's noise requirements based on the user's activity level, and then accurately adjusts the speed of the refrigerator's compressor and fan according to different noise requirements, which can achieve accurate noise control and minimize noise while ensuring the refrigeration effect.

[0063] As mentioned above, the noise requirement for the environment during the user's active period is the lowest. Therefore, during this period, the refrigeration demand should be met first. Therefore, the speed gear of the compressor and fan in the refrigerator is controlled according to the current period and the environmental noise value, including: judging whether the current period is an active period; if the current period is an active period, controlling the speed gear of the compressor and fan in the refrigerator to switch to the third gear to meet the refrigeration demand. The third gear is the gear for normal operation. The higher the speed gear, the higher the speed; if the current period is not an active period, it is necessary to control the speed gear of the compressor and fan in the refrigerator according to the current period and the range of the environmental noise value.

[0064] The noise requirement during the leisure period is lower than that during the sleeping period. Therefore, the control strategies adopted for the leisure period and the sleeping period are different. Therefore, the speed gear of the compressor and the fan in the refrigerator are controlled according to the current period and the interval of the ambient noise value, including: if the current period is the leisure period, the interval of the ambient noise value is obtained; if the ambient noise value is less than the first noise threshold, the speed gear of the compressor and the fan is controlled to switch to the first gear; if the ambient noise value is greater than or equal to the first noise threshold and less than the second noise threshold, the speed gear of the compressor and the fan is controlled to switch to the second gear; if the ambient noise value is greater than or equal to the second noise threshold, the speed gear of the compressor and the fan in the refrigerator is controlled to switch to the third gear.

[0065] Since the requirement for noise is highest during the sleep period, it is necessary to control the compressor and the fan to maintain a lower speed gear. The speed gear will be increased only if the ambient noise is high and the user's activity is high, that is, the ambient noise threshold for switching from the second speed gear to the second speed gear needs to be increased. In addition, during the sleep period, it is unlikely that the ambient noise reaches the fourth noise threshold. If the fourth noise threshold is reached, it means that the user's activity is very high and the requirement for noise is also low. Therefore, the fourth noise threshold can be equal to or slightly greater than the human noise threshold. In summary, if the current period is the sleep period, the interval of the ambient noise value is obtained; if the ambient noise value is less than the third noise threshold, the speed gear of the compressor and the fan is controlled to switch to the first gear; if the ambient noise value is greater than or equal to the third noise threshold and less than the fourth noise threshold, the speed gear of the compressor and the fan is controlled to switch to the second gear; if the ambient noise value is greater than or equal to the fourth noise threshold, the speed gear of the compressor and the fan in the refrigerator is controlled to switch to the third gear; wherein the third noise threshold is greater than the above-mentioned first noise threshold, and the fourth noise threshold is greater than or equal to the above-mentioned second noise threshold.

[0066] The ambient temperature and the freezing temperature difference can reflect the refrigeration demand. In order to give priority to the refrigeration effect when the refrigeration demand is high, before controlling the speed gear of the compressor and the fan in the refrigerator according to the current time period and the interval of the ambient noise value, the above method also includes: obtaining the ambient temperature and the freezing temperature difference; controlling the speed gear of the compressor and the fan according to the ambient temperature and the freezing temperature difference. Specifically, controlling the speed gear of the compressor and the fan according to the ambient temperature and the freezing temperature difference includes: judging whether the ambient temperature is less than the preset temperature and the freezing temperature difference is less than the preset temperature difference; if not, it indicates that the current refrigeration demand is relatively high, and the refrigeration effect should be given priority, and the speed gear of the compressor and the fan in the refrigerator is controlled to switch to the third gear; if yes, it indicates that the current refrigeration demand is relatively low, and noise control can be given priority, therefore, triggering the control of the speed gear of the compressor and the fan in the refrigerator according to the current time period and the interval of the ambient noise value.

[0067] Taking into account that different groups of people may have different requirements for noise time periods, or have special requirements for noise sensitivity, the low speed time period, ambient temperature, freezing temperature difference and noise threshold can all be adjusted through the refrigerator display panel. Therefore, the above method also includes: in response to user instructions, adjusting at least one of the above preset temperature, the above preset temperature difference, the above first noise threshold, the above second noise threshold, the third noise threshold, and the fourth noise threshold; and in response to user instructions, adjusting the start and end times of the above active period, the above leisure period and the above sleep period.

[0068] Example 2

[0069] This embodiment provides another noise control method. Figure 2 is a flow chart of a noise control method according to another embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0070] S1, adjusting the timing time of the refrigerator to synchronize with the current time, and then determining the current time period according to the timing time of the refrigerator.

[0071] Refrigerator controller timing. In order to ensure the accuracy and effectiveness of the refrigerator controller timing, the user needs to initialize and set the refrigerator time through the refrigerator display panel according to the current actual time after the refrigerator is powered on, in accordance with the requirements of the refrigerator manual. After that, the refrigerator timing will work normally.

[0072] S2, obtaining the environmental noise value.

[0073] S3, judging whether it is necessary to control the compressor and the fan to run at a low speed according to the current time period and the ambient noise value; if yes, executing step S4, if not, executing step S5.

[0074] S4, controls the compressor and fan to run at low speed.

[0075] S5, controls the compressor and fan to run at normal speed.

[0076] The speed level of the compressor and fan of the refrigerator is controlled according to the parameter range shown in Table 1 below. The time division, ambient temperature threshold, freezing temperature difference threshold (difference between freezing compartment temperature and freezing preset temperature) and noise threshold of the refrigerator are shown in the following table. The situations not included in the table are controlled according to the normal speed (third speed level). The time period, noise value, ambient temperature, freezing temperature difference and speed level in the table are only for example.

[0077] Table 1 Speed ​​and gear control table of compressor and fan

[0078]

[0079] As shown in the above table, when the refrigerator timing time is in the leisure period (18:00-21:00), if the noise value detected by the sound sensor is less than the preset first noise threshold (35dB), and the ambient temperature and the freezing temperature difference are both less than the corresponding preset threshold, the refrigerator's compressor and fan are controlled to operate at the preset first speed gear; if the noise value is greater than or equal to the first noise threshold (35dB) and less than the preset second noise threshold (60dB), and the ambient temperature and the freezing temperature difference are both less than the corresponding preset threshold, the refrigerator's compressor and fan are controlled to operate at the preset second speed gear; if the noise value is greater than or equal to the second noise threshold (60dB), the compressor and fan are controlled to operate at the normal operating speed.

[0080] When the refrigerator timing time is in the sleep period (21:00-8:00), if the noise value detected by the sound sensor is less than the preset third noise threshold (45dB), and the ambient temperature and the freezing temperature difference are both less than the corresponding preset thresholds, the compressor and the fan of the refrigerator are controlled to operate at the preset first speed gear; if the noise value is greater than or equal to the third noise threshold (45dB) and less than the preset fourth noise threshold (60dB), and the ambient temperature and the freezing temperature difference are both less than the corresponding preset thresholds, the compressor and the fan of the refrigerator are controlled to operate at the preset second speed gear; if the noise value is greater than or equal to the fourth noise threshold (60dB), the compressor and the fan are controlled to operate at the normal operating speed.

[0081] Considering that different groups of people may have different requirements for noise time periods or special requirements for noise sensitivity, the low speed time period, ambient temperature threshold, freezing temperature difference threshold and noise threshold can all be adjusted through the refrigerator display panel. When the refrigerator display panel is activated, enter the low speed threshold setting program through the refrigerator display panel combination key. In this program, the default values ​​of the low speed time period, ambient temperature, freezing temperature difference and noise threshold can be changed through the refrigerator display panel key adjustment.

[0082] The noise control method of this embodiment determines the current time period through the refrigerator timing, and the ambient noise value detected by the sound sensor. When the ambient noise value is less than the preset noise threshold, and the difference between the ambient temperature and the freezing temperature is lower than the corresponding preset threshold, the compressor and the fan of the refrigerator are controlled to operate at a preset low speed to reduce the noise generated during the operation of the refrigerator; the problem of inaccurate judgment conditions caused by judging the environment of the refrigerator through the light sensor and the sound sensor is solved, and the impact of noise on people is reduced in a low-temperature environment, and the cooling effect is guaranteed in a high ambient temperature. The cooling needs and noise requirements are balanced.

[0083] Example 3

[0084] This embodiment provides a noise control device for implementing the noise control method of the above embodiment. Figure 3 : is a structural block diagram of a noise control device according to an embodiment of the present invention. Figure 3 As shown, the noise control device comprises:

[0085] The acquisition module 10 is used to obtain the current time period and the environmental noise value; wherein the current time period includes an active time period, a leisure time period and a sleeping time period.

[0086] Refrigerator controller timing. In order to ensure the accuracy and effectiveness of the refrigerator controller timing, the user needs to initialize and set the refrigerator time through the refrigerator display panel according to the current actual time after the refrigerator is powered on, in accordance with the requirements of the refrigerator manual. After that, the refrigerator timing will work normally.

[0087] The control module 20 is used to control the speed level of the compressor and the fan in the refrigerator according to the current time period and the ambient noise value.

[0088] The current time period can accurately reflect the user's work and rest state. For example, a day can be divided into three time periods: 8:00-18:00 is the user's active time period, 18:00-21:00 is the user's leisure time period, and 21:00-8:00 is the user's sleep time period. According to life experience, the higher the user's activity level, the lower the noise requirement, and the lower the user's activity level, the higher the noise requirement. Therefore, the active time period has the lowest noise requirement, while the sleep time period has the highest noise requirement. In addition, since people's work and rest states are not static, it is also possible that after the user's sleep time period is reached on a certain day, the user's activities are still relatively active, and the user's activities will cause noise in the environment. That is to say, the environmental noise value can also reflect the user's activity level to a certain extent. Therefore, combined with the current time period and the environmental noise value, the user's activity level can be judged more accurately. Controlling the speed gear of the compressor and the fan in the refrigerator according to the current time period and the environmental noise value can better meet the user's noise requirements.

[0089] The noise control device of this embodiment obtains the current time period and the ambient noise value through the acquisition module 10, and accurately determines the user's activity level based on the current time period and the ambient noise. Then, the control module 20 determines the user's noise requirements according to the user's activity level, and then accurately adjusts the speed of the refrigerator's compressor and fan according to different noise requirements. This can achieve accurate noise control and minimize noise while ensuring the refrigeration effect.

[0090] As mentioned above, the noise requirement for the environment during the user's active period is the lowest. Therefore, during this period, the cooling demand should be met first. Therefore, when the control module 20 controls the speed gear of the compressor and fan in the refrigerator according to the current period and the environmental noise value, the following specific operations are performed: determine whether the current period is an active period; if the current period is an active period, control the speed gear of the compressor and fan in the refrigerator to switch to the third gear to meet the cooling demand. The third gear is the gear for normal operation. The higher the speed gear, the higher the speed; if the current period is not an active period, it is necessary to control the speed gear of the compressor and fan in the refrigerator according to the current period and the range of the environmental noise value.

[0091] The noise requirement during the leisure period is lower than that during the sleep period. Therefore, the control strategies adopted for the leisure period and the sleep period are different. Therefore, when the control module 20 controls the speed gear of the compressor and the fan in the refrigerator according to the current period and the interval of the ambient noise value, the following operations are specifically performed: if the current period is the leisure period, the interval of the ambient noise value is obtained; if the ambient noise value is less than the first noise threshold, the speed gear of the compressor and the fan is controlled to switch to the first gear; if the ambient noise value is greater than or equal to the first noise threshold and less than the second noise threshold, the speed gear of the compressor and the fan is controlled to switch to the second gear; if the ambient noise value is greater than or equal to the second noise threshold, the speed gear of the compressor and the fan in the refrigerator is controlled to switch to the third gear.

[0092] Since the requirement for noise is highest during the sleep period, it is necessary to control the compressor and the fan to maintain a low speed gear. The speed gear will be increased only if the ambient noise is high and the user's activity is high. That is, the ambient noise threshold for switching from the second speed gear to the second speed gear needs to be increased. In addition, during the sleep period, it is unlikely that the ambient noise will reach the fourth noise threshold. If the fourth noise threshold is reached, it means that the user's activity is very high and the requirement for noise is also low. Therefore, the fourth noise threshold can be equal to or slightly greater than the human noise threshold. In summary, the control module 20 controls the compressor in the refrigerator according to the current time period and the interval of the ambient noise value. and the speed gear of the fan, the following operations are also specifically performed: when the current time period is the sleep time period, the interval of the ambient noise value is obtained; if the ambient noise value is less than the third noise threshold, the speed gear of the compressor and the fan is controlled to switch to the first gear; if the ambient noise value is greater than or equal to the third noise threshold, and less than the fourth noise threshold, the speed gear of the compressor and the fan is controlled to switch to the second gear; if the ambient noise value is greater than or equal to the fourth noise threshold, the speed gear of the compressor and the fan in the refrigerator is controlled to switch to the third gear; wherein the third noise threshold is greater than the above-mentioned first noise threshold, and the fourth noise threshold is greater than or equal to the above-mentioned second noise threshold.

[0093] The ambient temperature and the freezing temperature difference can reflect the refrigeration demand. In order to give priority to the refrigeration effect when the refrigeration demand is high, the control module 20 is also used to obtain the ambient temperature and the freezing temperature difference before controlling the speed gear of the compressor and the fan in the refrigerator according to the current time period and the interval of the ambient noise value; the speed gear of the compressor and the fan is controlled according to the ambient temperature and the freezing temperature difference. Specifically, the speed gear of the compressor and the fan is controlled according to the ambient temperature and the freezing temperature difference, including: judging whether the ambient temperature is less than the preset temperature and the freezing temperature difference is less than the preset temperature difference; if not, it indicates that the current refrigeration demand is relatively high, and the refrigeration effect should be given priority, and the speed gear of the compressor and the fan in the refrigerator is controlled to switch to the third gear; if yes, it indicates that the current refrigeration demand is relatively low, and noise control can be given priority, therefore, triggering the control of the speed gear of the compressor and the fan in the refrigerator according to the current time period and the interval of the ambient noise value.

[0094] Taking into account that different groups of people may have different requirements for noise time periods, or have special requirements for noise sensitivity, the low-speed time period, ambient temperature, freezing temperature difference and noise threshold can all be adjusted through the refrigerator display panel. Therefore, the above-mentioned control module 20 is also used to: respond to user instructions, adjust at least one of the above-mentioned preset temperature, the above-mentioned preset temperature difference, the above-mentioned first noise threshold, the above-mentioned second noise threshold, the third noise threshold, and the fourth noise threshold; and respond to user instructions to adjust the start and end times of the above-mentioned active period, the above-mentioned leisure period and the above-mentioned sleep period.
