[0047] like Figure 1-Figure 3 As shown, the present invention provides an anti-condensation control method for controlling a heating device in a refrigerator to eliminate condensation on the surface of a beam in the refrigerator. The anti-condensation control method includes:

[0048] S200, after determining that condensation occurs on the surface of the refrigerator center beam, determine the amount of condensation on the surface of the refrigerator center beam according to real-time image information of the surface of the refrigerator center beam.

[0049] The real-time image information of the refrigerator center beam surface is analyzed to determine the condensation area of ​​the refrigerator center beam surface and the number of water droplets in the condensation area. In some embodiments, the condensation amount is generally calculated as the quotient of the total number of water droplets and the total area of ​​the condensation area. For example, if the total number of water droplets is G and the total area of ​​the condensation area is S, then the condensation amount L = G / S.

[0050] S300: Determine the activation time and operating power of the heating device according to the operating mode of the refrigerator.

[0051] Among them, the operating modes of the refrigerator generally include energy-saving mode and non-energy-saving mode. In the non-energy-saving mode, the heating device can be turned on at full power and for as long as possible, giving priority to condensation removal efficiency; in the energy-saving mode, the heating device is generally turned on at a lower power, mainly to save energy consumption of the refrigerator.

[0052] S400, when it is determined that the refrigerator is in a non-energy-saving mode, determining a start time and an operating power of a heating device according to the amount of condensation and a set temperature of a compartment of the refrigerator.

[0053] Among them, the compartment setting temperature is the temperature that the compartment should maintain, which is generally reflected in the temperature gear of the compartment. For example, the higher the temperature gear of the compartment, the lower the compartment setting temperature. For example, the temperature gear of the compartment includes three gears: low, medium and high. Among them, when the temperature gear of the compartment is low, the compartment setting temperature corresponds to -5°C; when the temperature gear of the compartment is medium, the compartment setting temperature corresponds to -15°C; when the temperature gear of the compartment is high, the compartment setting temperature corresponds to -25°C. Some refrigerators can also set the compartment setting temperature by customizing.

[0054] The duration of the heating device being turned on is the total duration from when the heating device is turned on to when the heating device is turned off.

[0055] The operating power is the working power of the heating device after the heating device is turned on this time.

[0056] Among them, when the refrigerator is in non-energy-saving mode, the refrigerator can determine the operating state of the heating device according to the condensation amount and the setting temperature of the refrigerator compartment without considering energy consumption. Therefore, when the setting temperature of the compartment is low, the operating power and the opening time of the heating device can be increased to reduce the impact of the low compartment temperature on the decondensation effect.

[0057] S500: When it is determined that the refrigerator is in the energy-saving mode, the activation time and the operating power of the heating device are determined according to the amount of condensation.

[0058] Among them, referring to the control method of the heating device in S400, in the energy-saving mode, due to the need to consider energy consumption, the heating device is difficult to operate at a higher power to eliminate the impact of the low chamber temperature setting on the decondensation effect, so it is necessary to determine the specific opening time and operating power of the heating device according to the condensation amount.

[0059] It can be understood that the anti-condensation control method determines the amount of condensation on the surface of the refrigerator center beam through real-time image information of the surface of the refrigerator center beam, and determines the activation time and operating power of the heating device according to the operating mode of the refrigerator and the amount of condensation; that is, the present invention can turn on the heating device according to the actual condensation situation, thereby avoiding turning on the heating device when there is no condensation, and improving the accuracy of turning on the heating device.

[0060] In some embodiments, S400, when it is determined that the refrigerator is in a non-energy-saving mode, determining the activation time and operating power of the heating device according to the condensation amount and the set temperature of the compartment of the refrigerator includes:

[0061] S410: Determine a first preset power and a first preset time corresponding to the condensation amount.

[0062] Among them, the controller of the refrigerator has multiple first preset powers and multiple first preset time lengths, and the only first preset power and first preset time length corresponding to the current condensation amount can be determined according to the condensation amount.

[0063] S420: When it is determined that the set temperature of the compartment is lower than the preset temperature, the heating device is turned on at a first preset power and a first preset time.

[0064] Among them, the preset temperature is a temperature value stored in the controller of the refrigerator, which is generally a boundary representing the degree of influence of the compartment setting temperature on the heating device to eliminate condensation on the refrigerator beam. If the compartment setting temperature is lower than the preset temperature, it means that the compartment setting temperature is low, which has a greater impact on the heating device to eliminate condensation on the refrigerator beam, and will greatly reduce the efficiency of the heating device to eliminate condensation.

[0065] After determining that the set temperature of the compartment is lower than the preset temperature, the heating device is turned on with a first preset power and runs for a first preset time.

[0066] Among them, the first preset power and the first preset time are operating parameters of the heating device determined in consideration of the negative impact of too low compartment temperature setting on eliminating condensation in the refrigerator center beam. Therefore, when the heating device operates based on the first preset power and the first preset time, it can avoid the impact of too low compartment temperature setting and elimination of condensation.

[0067] S430, when it is determined that the set temperature of the compartment is greater than or equal to the preset temperature, the heating device is turned on at a power lower than the first preset power and a first preset time, or the heating device is turned on at the first preset power and a turn-on time shorter than the first preset time, or the heating device is turned on at a power lower than the first preset power and a turn-on time shorter than the first preset time.

[0068] Among them, when the compartment setting temperature is greater than or equal to the preset temperature, it means that the current compartment setting temperature is high, and the effect of the heating device on eliminating condensation on the surface of the refrigerator beam is weak. Therefore, relative to the case where the compartment setting temperature is lower than the preset temperature, for the same condensation amount, the heating device can be turned on with a power lower than the first preset power and / or a turn-on time shorter than the first preset time.

[0069] For example: when the condensation amount is L1 and the compartment setting temperature is less than the preset temperature, the first preset power determined by the heating device is 150W, and the heating device is turned on for 5 minutes at the first preset power; when the condensation amount is L1 and the compartment setting temperature is greater than or equal to the preset temperature, the heating device is turned on for 4 minutes at 130W; or when the condensation amount is L1 and the compartment setting temperature is greater than or equal to the preset temperature, the heating device is turned on for 4 minutes at 150W; or when the condensation amount is L1 and the compartment setting temperature is greater than or equal to the preset temperature, the heating device is turned on for 5 minutes at 130W.

[0070] That is, under the same condensation amount, when the compartment setting temperature is lower than the preset temperature, the heating device can be turned on with a higher power or longer opening time relative to the compartment setting temperature being greater than or equal to the preset temperature, so as to eliminate the influence of the compartment setting temperature being too low on the heating device to eliminate condensation.

[0071] In some embodiments, when the compartment setting temperature is equal to the preset temperature, the corresponding first preset power and the corresponding first preset duration are determined according to the condensation amount, and the heating device is turned on at a power lower than the first preset power and the first preset duration.

[0072] In some embodiments, when the compartment setting temperature is equal to the preset temperature, the corresponding first preset power and the corresponding first preset duration are determined according to the condensation amount, and the heating device is turned on according to the first preset power and the turn-on duration shorter than the first preset duration.

[0073] In some embodiments, when the compartment set temperature is greater than the preset temperature, the corresponding first preset power and the corresponding first preset duration are determined according to the condensation amount, and the heating device is turned on at a power lower than the first preset power and a turn-on time shorter than the first preset time.

[0074] In some embodiments, S410, determining a first preset power corresponding to the condensation amount and a first preset opening time corresponding to the condensation amount includes:

[0075] S411, determining a corresponding condensation amount range according to the condensation amount.

[0076] Among them, a plurality of condensation amount ranges are pre-stored in the controller of the refrigerator, such as: A1, A2, A3; each condensation amount can find a corresponding condensation amount range, and then the corresponding condensation amount range can be determined according to the condensation amount.

[0077] S412: Determine a first preset power corresponding to the condensation amount range according to the condensation amount range.

[0078] Among them, multiple powers are pre-stored in the refrigerator controller, which correspond one-to-one to multiple condensation amount ranges. For example, the multiple powers include a first power, a second power and a third power, which correspond one-to-one to three condensation amount ranges A1, A2 and A3 respectively. Therefore, after determining the condensation amount, the corresponding first preset power can be determined.

[0079] S413: Determine a first preset time duration corresponding to the condensation amount range according to the condensation amount range.

[0080] Among them, the refrigerator controller pre-stores multiple preset time lengths, which correspond one-to-one to multiple condensation amount ranges, such as the multiple preset time lengths include a first time length, a second time length, and a third time length, which correspond one-to-one to the three condensation amount ranges A1, A2, and A3, respectively. Therefore, after determining the condensation amount, the corresponding first preset time length can be determined.

[0081] In some embodiments, S500, when it is determined that the refrigerator is in the energy-saving mode, determining the activation time and operating power of the heating device according to the condensation amount includes:

[0082] S510: Determine a second preset power corresponding to the condensation amount according to the condensation amount.

[0083] Among them, a plurality of second preset powers are pre-stored in the controller of the refrigerator. After the second preset power is determined, the heating device is turned on and operates at the power corresponding to the second preset power.

[0084] S520: Turn on the heating device at a second preset power, and turn off the heating device after a second preset time has passed.

[0085] Among them, the second preset duration is the duration of each time the heating device is turned on in the energy-saving mode, which is pre-stored in the controller of the refrigerator. It is generally shorter than the duration of the heating device being turned on in the non-energy-saving mode at the same condensation amount.

[0086] S530, after turning off the heating device, determine the condensation state of the surface of the refrigerator center beam at a third preset time interval, and if condensation exists on the surface of the refrigerator center beam, repeat the above steps.

[0087] Among them, the third preset time length is data pre-stored in the refrigerator controller. After the third preset time length, it is determined again whether there is condensation on the surface of the refrigerator center beam by implementing image information. After determining that there is condensation on the surface of the refrigerator center beam, S510-S530 are repeated.

[0088] Among them, the third preset time is generally 60 minutes. By making the activation interval of the heating device at least the third preset time, the burden of frequent activation of the heating device on the energy consumption of the refrigerator is reduced.

[0089] In some embodiments, S510, determining a second preset power corresponding to the condensation amount according to the condensation amount includes:

[0090] S511, determining a corresponding condensation amount range according to the condensation amount.

[0091] Among them, a plurality of condensation amount ranges are pre-stored in the controller of the refrigerator, such as: A1, A2, A3; each condensation amount can find a corresponding condensation amount range, and then the corresponding condensation amount range can be determined according to the condensation amount.

[0092] S512, determining a first preset power corresponding to a condensation amount range in a non-energy-saving mode.

[0093] Among them, multiple powers are pre-stored in the refrigerator controller, which correspond one-to-one to multiple condensation amount ranges. For example, the multiple powers include a first power, a second power and a third power, which correspond one-to-one to three condensation amount ranges A1, A2 and A3 respectively. Therefore, after determining the condensation amount, the corresponding first preset power can be determined.

[0094] S513: Determine a second preset power according to the first preset power, where the second preset power is lower than or equal to 0.8 times of the first preset power.

[0095] The first preset power is the power determined based on the amount of condensation when the refrigerator is in non-energy-saving mode, the second preset power is determined based on the first preset power, and the second preset power is limited to be lower than or equal to 0.8 times the first preset power. For example, when the power corresponding to the first power determined based on the amount of condensation is 150W, the power corresponding to the second preset power shall not be higher than 120W.

[0096] In some embodiments, the anti-condensation control method further includes:

[0097] S600, the activation time, operating power, time from activation of the heating device to disappearance of condensation, condensation amount and environmental data of each heating device are substituted into the prediction model, and the activation time and operating power of the heating device next time under the same condensation amount and the same environmental data are determined by the prediction model.

[0098] Among them, environmental data includes the set temperature of the compartment and the humidity inside the refrigerator.

[0099] For example, the room temperature is set to -5℃, the ambient humidity is 60%, the heating device is turned on for 10 minutes, the operating power is 100W, and the time from turning on the heating device to the disappearance of condensation is 8 minutes. Substitute the above data into the prediction model, the prediction model records the data, and calculates through the algorithm that the next time the same condensation amount and the same environmental data, the heating device will be turned on for 8 minutes and the operating power will be 100W. That is, the heating device is turned on for the same time as the disappearance of condensation, thereby avoiding the heating device from continuing to work and wasting energy after the condensation disappears.

[0100] The prediction model can also record the environmental data each time condensation occurs, and predict the occurrence of condensation based on the environmental data, so as to specifically turn on the heating device before condensation occurs to prevent condensation from occurring.

[0101] In some embodiments, S200, determining the amount of condensation on the surface of the refrigerator center beam according to the real-time image information of the refrigerator center beam surface includes:

[0102] The amount of condensation on the center beam surface is determined based on the condensation area and the number of water drops in the real-time image information.

[0103] The condensation amount is generally calculated as the quotient of the total number of water droplets and the total area of ​​the condensation area. For example, if the total number of water droplets is G and the total area of ​​the condensation area is S, the condensation amount L=G / S.

[0104] In some embodiments, the anti-condensation control method further includes:

[0105] S100, determining whether condensation occurs on the surface of the refrigerator center beam according to real-time image information of the refrigerator center beam surface.

[0106] The controller of the refrigerator recognizes the real-time image information, and when it recognizes that water droplets appear on the surface of the refrigerator center beam, it determines that condensation appears on the surface of the refrigerator center beam.

[0107] In order to ensure the accuracy of the recognition of real-time image information, after the image acquisition device acquires the image, the controller performs denoising and contrast enhancement on the real-time image information to improve the recognition of water droplets in the image.

[0108] In some embodiments, the present invention further provides an anti-condensation control device 10, comprising an acquisition module 100, a processing module 200 and a control module 300. The acquisition module 100 is used to acquire real-time image information of the surface of the refrigerator beam, the compartment setting temperature of the refrigerator and the operating mode of the refrigerator. The processing module 200 is used to determine the amount of condensation on the surface of the refrigerator beam according to the real-time image information of the refrigerator beam after determining that condensation occurs on the surface of the refrigerator beam. The control module 300 is used to determine the opening time and operating power of the heating device according to the operating mode of the refrigerator. The control module 300 is used to determine the opening time and operating power of the heating device according to the condensation amount and the compartment setting temperature of the refrigerator when determining that the refrigerator is in a non-energy-saving mode. The control module 300 is used to determine the opening time and operating power of the heating device according to the condensation amount and the compartment setting temperature of the refrigerator when determining that the refrigerator is in an energy-saving mode. The control module 300 is used to determine the opening time and operating power of the heating device according to the condensation amount when determining that the refrigerator is in an energy-saving mode.

[0109] In some embodiments, the present invention further provides a refrigerator, which may include one or more processors 601 of processing cores, one or more computer-readable storage media memories 602, a power supply 603, an input unit 604 and other components.
