[0038] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and explanation, and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of explanation, multiple details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be shown in a simplified manner to simplify the drawings.

[0039] Combined with Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a control method for a refrigeration device. The refrigeration device 100 includes an air supply fan 200 and a heating element 300, and the heating element 300 is arranged on the air supply fan 200. The control method of the refrigeration device includes:

[0040] S201. Obtain the operating mode of the refrigeration device 100.

[0041] In the embodiment of the present disclosure, by obtaining the operating mode of the refrigeration device 100, the target operating parameters corresponding to each operating mode can be determined, providing a prerequisite for obtaining the target operating parameters in each operating mode. Specifically, the operating modes of the refrigeration device 100 include a defrosting mode and a refrigeration mode.

[0042] S202. According to the operating mode, obtain the target operating parameters corresponding to the operating mode.

[0043] In the embodiment of the present disclosure, it is possible to obtain the target operating parameters corresponding to different operating modes. Specifically, the target operating parameters corresponding to the defrosting mode can be obtained. The target operating parameters corresponding to the refrigeration mode can also be obtained. Accurate target operating parameters are provided for the heating element 300 to work in different operating modes.

[0044] S203. Control the operation of the heating element 300 according to the target operating parameters.

[0045] In the embodiments of the present disclosure, by obtaining the operating mode of the refrigeration device 100, a prerequisite is provided for obtaining the target operating parameters corresponding to the operating mode. By obtaining the target operating parameters corresponding to the operating mode, the accuracy of obtaining the target operating parameters in different operating modes is improved, and thus the accurate control of the operation of the heating element 300 is achieved. According to the target operating parameters in different operating modes, the operation of the heating element 300 is controlled to effectively prevent the air supply fan 200 from icing or defrost the ice on the air supply fan 200 in different operating modes of the refrigeration device 100, improve the heating efficiency of the heating element 300, and reduce costs.

[0046] In the embodiments of the present disclosure, the heating element 300 is arranged on the air supply fan 200, so that when the heating element 300 heats, the temperature around the air supply fan 200 can be directly increased, and only a heating element 300 with a lower power is required to achieve the effect of preventing the air supply fan 200 from icing or defrosting the ice accumulated on the air supply fan 200, improving the heating efficiency, achieving energy conservation, and reducing costs.

[0047] It can be understood that the specific type of the heating element 300 is not limited, as long as it can heat the air supply fan 200. For example, the heating element 300 adopts a heating wire aluminum foil.

[0048] In practical applications, the refrigeration device 100 further includes a compressor, a condenser, an evaporator, etc., which are used to provide cold for the refrigerator compartment. The refrigeration process of the refrigeration device 100 adopts the existing technology and will not be elaborated here. The refrigeration device 100 further includes a refrigeration air duct, and the air supply fan 200 is used to supply air into the refrigeration air duct.

[0049] It can be understood that the refrigeration device 100 includes but is not limited to refrigerators, freezers, etc.

[0050] Optionally, as shown in Figure 1 The heating element 300 is arranged on the side of the air supply fan 200 away from the fan blade.

[0051] In practical applications, the air supply fan 200 is installed in the air duct of the refrigeration device 100 through a support member 400. A heat insulation member 500 is arranged between the support member 400 and the air duct, so that when the heating element 300 heats the air supply fan 200, other structures of the refrigeration device 100 will not be affected. The material of the heat insulation member 500 can adopt polyethylene (PE).

[0052] As shown in Figure 3As shown, an embodiment of the present disclosure provides a control method for a refrigeration device. The control method for the refrigeration device includes:

[0053] S301. Obtain the operating mode of the refrigeration device 100.

[0054] In an embodiment of the present disclosure, the operating mode of the refrigeration device 100 is a defrosting mode.

[0055] S302. When the operating mode is the defrosting mode, obtain the target operating parameters of the heating element 300. Among them, the target operating parameters include the heating power.

[0056] In an embodiment of the present disclosure, when the operating mode is the defrosting mode, obtain the heating power of the heating element 300, so as to heat the air supply fan 200 by the heating element 300 while the refrigeration device 100 is defrosting, and prevent the air supply fan 200 from freezing.

[0057] S303. Control the operation of the heating element 300 according to the target operating parameters.

[0058] In an embodiment of the present disclosure, according to the heating power of the heating element 300, by controlling the heating element 300 to operate at the heating power, the air supply fan 200 is prevented from freezing.

[0059] In practical applications, the refrigeration device 100 further includes a defrosting heating wire, a defrosting sensor, etc., which are used to defrost the evaporator when the operating mode of the refrigeration device 100 is the defrosting mode. The defrosting process of the refrigeration device 100 adopts the existing technology and will not be elaborated herein.

[0060] Exemplarily, as shown in combination with Figure 4 When the operating mode of the refrigeration device 100 is the defrosting mode, the defrosting heating wire works to defrost the evaporator. At the same time, the heating element 300 operates at the heating power to heat the air supply fan 200 to prevent the air supply fan 200 from freezing. When the refrigeration device 100 exits the defrosting mode, the heating element 300 stops heating, so as to heat the air supply fan 200 while defrosting, and prevent the air supply fan 200 from freezing. Moreover, during the defrosting process, the refrigeration device 100 cannot be refrigerated. By heating and deicing the air supply fan 200 while defrosting, it avoids deicing the air supply fan 200 during the refrigeration process, improves the refrigeration efficiency of the refrigeration device 100, and reduces the energy consumption.

[0061] It can be understood that the defrosting conditions for the refrigeration device 100 to operate in the defrosting mode are not limited. For example, when the compressor accumulates 8 hours of operation, or the compressor accumulates 6 hours of operation and the door opening time accumulates more than 10 minutes, or the compressor continuously operates for more than 5 hours, the defrosting mode is executed.

[0062] It can be understood that the conditions for the refrigeration device 100 to exit the defrosting mode are not limited. For example, when the temperature value collected by the defrosting sensor reaches 9°C or the defrosting heating wire works continuously for 70 minutes, the defrosting mode is exited.

[0063] Combined with Figure 5 As shown, the embodiments of the present disclosure provide a control method for a refrigeration device. The control method of the refrigeration device includes:

[0064] S501. Obtain the operating mode of the refrigeration device 100.

[0065] In the embodiments of the present disclosure, the operating mode of the refrigeration device 100 is the refrigeration mode.

[0066] S502. When the operating mode is the refrigeration mode, obtain the target operating parameters of the air supply fan 200. Among them, the target operating parameters include one or more of the air volume, noise, and current.

[0067] In the embodiments of the present disclosure, when the operating mode is the refrigeration mode, by obtaining one or more of the air volume, noise, and current of the air supply fan 200, it is realized to determine whether the air supply fan 200 is iced, that is, to determine whether there is ice slag or ice blockage on the air supply fan 200. Provide control conditions for controlling the operation of the heating element 300.

[0068] Specifically, when the air supply fan 200 is iced, the ice will block the air outlet duct of the air supply fan 200, thereby causing the air volume of the air supply fan 200 to decrease. Therefore, by obtaining the air volume of the air supply fan 200, it is possible to determine whether the air supply fan 200 is iced.

[0069] Specifically, when the air supply fan 200 is iced, the fan blades of the air supply fan 200 will collide with the ice during rotation, resulting in an increase in the operating noise of the air supply fan 200. Therefore, by obtaining the noise of the air supply fan 200, it is possible to determine whether the air supply fan 200 is iced.

[0070] Specifically, when the air supply fan 200 is iced, the ice will cause an increase in the operating load of the air supply fan 200, thereby causing an increase in the operating current of the air supply fan 200. Therefore, by obtaining the current of the air supply fan 200, it is possible to determine whether the air supply fan 200 is iced.

[0071] S503. Control the operation of the heating element 300 according to the target operating parameters.

[0072] In the embodiments of the present disclosure, by controlling the operation of the heating element 300 according to the target operating parameters, the heating efficiency and the accuracy of ice determination are improved to realize defrosting treatment of the ice on the air supply fan 200.

[0073] Combined Figure 6 As shown, the embodiments of the present disclosure provide a control method for a refrigeration device. The control method of the refrigeration device includes:

[0074] S601. Obtain the operating mode of the refrigeration device 100.

[0075] S602. When the operating mode is the refrigeration mode, obtain the target operating parameters of the air supply fan 200. Among them, the target operating parameters include one or more of the air volume, noise, and current.

[0076] S603. When the target operating parameters of the air supply fan 200 meet the preset conditions, determine the operating parameters of the heating element 300. Control the heating element 300 to operate according to the operating parameters.

[0077] In this embodiment, by determining the operating parameters of the heating element 300 when the target operating parameters of the air supply fan 200 meet the preset conditions, parameter preparation is provided for the operation of the heating element 300. By controlling the operation of the heating element 300 according to the operating parameters, accurate control of the operation of the heating element 300 is achieved.

[0078] In some embodiments, when the target operating parameters include the air volume, the preset condition is that the air volume is less than or equal to the air volume threshold.

[0079] In this embodiment, the air supply fan 200 is used to supply air into the refrigeration air duct. The air volume of the air supply fan 200 can be detected by an air volume sensor. The installation position of the air volume sensor is not limited. For example, the air volume sensor is installed at the air outlet position of the air supply fan 200 or at the air outlet of the refrigeration air duct.

[0080] In this embodiment, when the air supply fan 200 is iced up, the air volume of the air supply fan 200 will decrease. By the air volume of the air supply fan 200 being less than or equal to the air volume threshold, it is determined whether the air supply fan 200 has an icing phenomenon, so as to perform defrosting treatment by controlling the heating element 300 to heat.

[0081] Table 1

[0082]

[0083] Optionally, the air supply fan 200 includes a duty cycle speed control fan. The duty cycle range of the air supply fan 200 is from 50% duty cycle to 100% duty cycle. Correspondingly, the range of the air volume threshold is from 1.0 m 3 / min to 2.0 m 3 / min.

[0084] Exemplarily, the air supply fan 200 is a duty cycle speed control fan. As shown in Table 1, for the air supply fan 200 that is operating normally and has no ice accumulation, at different duty cycles, the air output of the air supply fan 200 is different. That is to say, at different duty cycles, the air volume threshold is different. When the air supply fan 200 operates at a 50% duty cycle, the air volume threshold is 1.0 m 3 / min. When the air supply fan 200 operates at a 60% duty cycle, the air volume threshold is 1.2 m 3 / min. When the air supply fan 200 operates at a 70% duty cycle, the air volume threshold is 1.4 m 3 / min. When the air supply fan 200 operates at an 80% duty cycle, the air volume threshold is 1.6 m 3 / min. When the air supply fan 200 operates at a 90% duty cycle, the air volume threshold is 1.8 m 3 / min. When the air supply fan 200 operates at a 100% duty cycle, the air volume threshold is 2.0 m 3 / min.

[0085] In this example, when the refrigeration device 100 operates in the refrigeration mode, both the compressor and the air supply fan 200 are working. At the same duty cycle, if the air output through the air supply fan 200 is less than or equal to the corresponding air volume threshold, it is determined that the air supply fan has ice accumulation, and the heating element 300 is controlled to heat for ice removal treatment.

[0086] Optionally, within 3 to 5 consecutive minutes, if the air output of the air supply fan 200 is less than or equal to the air volume threshold, the heating element 300 is controlled to heat.

[0087] In this embodiment, by determining that the air output of the air supply fan 200 is less than or equal to the air volume threshold within a continuous period of time (such as 5 minutes), it is determined that the air supply fan 200 has ice accumulation, improving the accuracy of the determination of ice accumulation.

[0088] In some embodiments, when the target operating parameters include noise, the preset condition is that the noise is greater than or equal to the noise threshold.

[0089] In this embodiment, when the air supply fan 200 has ice accumulation, the operating noise of the air supply fan 200 will increase. Whether the air supply fan 200 has ice accumulation can be judged by the noise during the operation of the air supply fan 200. When the noise is greater than or equal to the noise threshold, it is determined that the air supply fan 200 has ice accumulation, and the heating element 300 is controlled to work to heat the air supply fan 200 for de-icing treatment.

[0090] In this embodiment, the noise during the operation of the air supply fan 200 can be detected by a noise sensor. The installation position of the noise sensor is not limited. For example, the noise sensor is installed outside the air supply fan 200.

[0091] Optionally, the air supply fan 200 includes a duty cycle speed control fan. The operating parameters of the air supply fan 200 include a basic noise value corresponding to the duty cycle of the air supply fan 200. When the duty cycle is the same, the noise threshold is greater than the basic noise value.

[0092] Optionally, the duty cycle range of the air supply fan 200 is from 50% duty cycle to 100% duty cycle. Correspondingly, the range of the difference between the noise threshold and the basic noise value is from 5 dB to 5.7 dB.

[0093] Exemplarily, for the air supply fan 200 that is operating normally and has no ice accumulation, the noise during the operation of the air supply fan 200 is used as the basic noise value of the air supply fan 200. The air supply fan 200 uses a duty cycle speed control fan. At different duty cycles, the basic noise value of the air supply fan 200 is different. When the duty cycle is the same, the noise threshold is greater than the basic noise value. At different duty cycles, the differences between the noise threshold and the basic noise value are shown in Table 1. When the air supply fan 200 operates at a 50% duty cycle, the difference between the noise threshold and the basic noise value is 5 dB. When the air supply fan 200 operates at a 60% duty cycle, the difference between the noise threshold and the basic noise value is 5.2 dB. When the air supply fan 200 operates at a 70% duty cycle, the difference between the noise threshold and the basic noise value is 5.4 dB. When the air supply fan 200 operates at an 80% duty cycle, the difference between the noise threshold and the basic noise value is 5.5 dB. When the air supply fan 200 operates at a 90% duty cycle, the difference between the noise threshold and the basic noise value is 5.6 dB. When the air supply fan 200 operates at a 100% duty cycle, the difference between the noise threshold and the basic noise value is 5.7 dB.

[0094] In this example, when the refrigeration device 100 operates in the refrigeration mode, both the compressor and the air supply fan 200 are working. When the duty cycle is the same, if the noise passing through the air supply fan 200 is greater than or equal to the corresponding noise threshold, it is determined that ice accumulation has occurred in the air supply fan, and the heating element 300 is controlled to heat for de-icing treatment.

[0095] Optionally, when the target operating parameters include noise, obtaining the target operating parameters of the air supply fan includes the number of consecutive noise acquisitions. When the number of noise acquisitions is greater than or equal to a preset number and each acquired noise is greater than or equal to the noise threshold, the heating element is controlled to operate.

[0096] Optionally, the preset number is greater than or equal to 5 times. For example, the number of consecutive noise acquisitions is 5 times, 6 times, 7 times, 8 times, 9 times, 10 times, 11 times, 12 times.

[0097] In this embodiment, when the noise obtained each time is greater than or equal to the noise threshold among the continuously obtained noise times, it is determined that the air supply fan 200 has an icing phenomenon, which improves the accuracy of determining the icing phenomenon.

[0098] Exemplarily, the noise of the air supply fan is continuously obtained 10 times. When each of the 10 obtained noises is greater than or equal to the noise threshold, the heating element 300 is controlled to heat.

[0099] It can be understood that the time interval for continuously obtaining the noise is not limited. For example, the noise is obtained once every 100 ms.

[0100] In some embodiments, when the target operating parameter includes noise, the noise is obtained in the following manner: the operating noise of the air supply fan 200 in the range of 2 KHz to 4 KHz of the noise frequency is obtained.

[0101] In this embodiment, when the air supply fan 200 has an icing phenomenon, the noise when the air supply fan 200 works is sharp. By obtaining the noise in the range of 2 KHz to 4 KHz of the noise frequency, the accuracy of determining the icing phenomenon is improved.

[0102] In some embodiments, when the target operating parameter includes current, the preset condition is that the current is greater than or equal to the current threshold.

[0103] In this embodiment, the icing of the air supply fan 200 increases the operating load of the air supply fan 200, resulting in an increase in the operating current of the air supply fan 200. Whether the air supply fan 200 has an icing phenomenon can be judged by the current when the air supply fan 200 operates. When the current is greater than or equal to the noise threshold, it is determined that the air supply fan 200 has an icing phenomenon, and the heating element 300 is controlled to work to heat the air supply fan 200 for defrosting treatment.

[0104] In this embodiment, the method for detecting the current when the air supply fan 200 operates is not limited. For example, the current detection function can be added to the main control board to detect the current when the air supply fan 200 operates.

[0105] In this embodiment, the air supply fan 200 is a duty cycle speed regulation fan. When the refrigeration device 100 is used for the first time, the air supply fan 200 operates at 50%, 60%, 70%, 80%, 90% and 100% duty cycles for 2 minutes respectively, and the current when the air supply fan 200 operates at each duty cycle is stored as the basic current value. When the duty cycle is the same, the current threshold is greater than the basic current value. By the current threshold being greater than the basic current value, a reasonable fluctuation range is provided for the current when the air supply fan 200 operates, which improves the accuracy of determining that the air supply fan 200 has an icing phenomenon through the current.

[0106] In some embodiments, when the target operating parameters include the air volume and the noise, the preset condition is that the air volume is less than or equal to the air volume threshold, and the noise is greater than or equal to the noise threshold.

[0107] In this embodiment, by combining the reduction of the air volume of the air supply fan 200 with the increase of the operating noise, it is determined that the air supply fan 200 has an icing phenomenon, improving the accuracy of icing determination.

[0108] In some embodiments, when the target operating parameters include the air volume and the current, the preset condition is that the air volume is less than or equal to the air volume threshold, and the current is greater than or equal to the current threshold.

[0109] In this embodiment, by combining the reduction of the air volume of the air supply fan 200 with the increase of the operating current, it is determined that the air supply fan 200 has an icing phenomenon, improving the accuracy of icing determination.

[0110] In some embodiments, when the target operating parameters include the noise and the current, the preset condition is that the noise is greater than or equal to the noise threshold, and the current is greater than or equal to the current threshold.

[0111] In this embodiment, by combining the increase of the operating noise of the air supply fan 200 with the increase of the operating current, it is determined that the air supply fan 200 has an icing phenomenon, improving the accuracy of icing determination.

[0112] In some embodiments, when the target operating parameters include the air volume, the noise, and the current, the preset condition is that the air volume is less than or equal to the air volume threshold, the noise is greater than or equal to the noise threshold, and the current is greater than or equal to the current threshold.

[0113] In this embodiment, by combining the reduction of the air volume of the air supply fan 200, the increase of the operating noise, and the increase of the operating current, it is determined that the air supply fan 200 has an icing phenomenon, improving the accuracy of icing determination.

[0114] In some embodiments, the working parameters include the heating power and the first preset duration. According to the working parameters, the steps of controlling the heating element 300 to operate include: controlling the heating element 300 to operate at the heating power for the first preset duration.

[0115] In this embodiment, by controlling the heating element 300 to operate at the heating power for the first preset duration, the defrosting process of the air supply fan 200 is realized.

[0116] In some embodiments, during the process of controlling the heating element 300 to operate, the air supply fan 200 is controlled to start and work for the second preset duration.

[0117] In this embodiment, during the operation of the heating element 300, the air supply fan 200 is started to shake off the defrosting ice water, preventing the defrosting ice water from freezing again after the heating element 300 stops heating, and improving the defrosting effect.

[0118] Optionally, the second preset duration is less than or equal to the first preset duration.

[0119] Exemplarily, as shown in combination with Figure 7 , when the operating mode of the refrigeration device 100 is the refrigeration mode, both the compressor and the air supply fan 200 of the refrigeration device 100 are operating. The target operating parameters of the air supply fan 200 are obtained. When the target operating parameters of the air supply fan 200 meet the preset conditions, both the compressor and the air supply fan 200 are controlled to stop operating. The heating element 300 is controlled to heat for the first preset duration (for example, 10 minutes). During the heating process of the heating element 300, for example, 5 minutes after the heating element 300 starts heating, the air supply fan 200 is controlled to start and rotate at a 50% duty cycle to shake off the defrosting ice water. Until the heating element 300 stops heating, the air supply fan 200 stops operating. Then, the compressor and the air supply fan 200 are started again to perform the refrigeration mode until the refrigeration mode ends. When the target operating parameters of the air supply fan 200 do not meet the preset conditions, the refrigeration device 100 maintains the refrigeration mode until the refrigeration mode ends.

[0120] It can be understood that the end condition of the refrigeration mode of the refrigeration device 100 adopts the existing technology and will not be elaborated herein.
