[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 with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only, and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of explanation, a sufficient understanding of the disclosed embodiments is provided through multiple details. 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 refrigeration device. The refrigeration device includes an air supply fan 100 and a heating element 200, and the heating element 200 is arranged on the air supply fan 100.

[0040] In the embodiment of the present disclosure, the heating element 200 is arranged on the air supply fan 100. By heating with the heating element 200, the temperature around the air supply fan 100 can be directly increased, and the effect of defrosting the air supply fan 100 can be achieved only with a heating element 200 of relatively low power, which improves the heating efficiency, realizes energy saving and consumption reduction, and reduces the cost.

[0041] It can be understood that the specific type of the heating element 200 is not limited as long as it can heat the air supply fan 100. For example, the heating element 200 adopts a heating wire aluminum foil.

[0042] In practical applications, the refrigeration device further includes a compressor, a condenser, an evaporator, etc., which are used to provide cooling capacity for the refrigerator compartment. The refrigeration process of the refrigeration device adopts the existing technology and will not be elaborated herein.

[0043] It can be understood that the refrigeration equipment includes but is not limited to refrigerators, freezers, etc.

[0044] Combined with Figure 1 and Figure 2 As shown, optionally, the air supply fan 100 includes a fan bracket 101 and a fan impeller 102 disposed on the fan bracket 101. The heating element 200 is disposed on a side of the fan bracket 101 away from the fan impeller 102.

[0045] In this embodiment, by disposing the heating element 200 on a side of the fan bracket 101 away from the fan impeller 102, the heating efficiency is improved, the defrosting treatment of the ice slag or ice blockage of the air supply fan 100 can be realized, the requirement for the power of the heating element 200 and the energy consumption are reduced, and the cost is reduced.

[0046] Combined with Figure 1 As shown, optionally, the refrigeration equipment further includes a refrigeration air duct, a support member 300, and a heat insulation member 400. The fan bracket 101 is connected to the support member 300. The support member 300 is installed on the refrigeration air duct. The heat insulation member 400 is disposed between the support member 300 and the refrigeration air duct.

[0047] In this embodiment, the air supply fan 100 is installed on the refrigeration air duct through the support member 300. A heat insulation member 400 is disposed between the support member 300 and the refrigeration air duct, so that when the heating element 200 heats the air supply fan 100, other structures of the refrigeration equipment are not affected. The material of the heat insulation member 400 can be polyethylene (PE).

[0048] Combined with Figure 1 and Figure 2 As shown, optionally, the air supply fan 100 further includes an air inlet 103 and an air outlet. The air inlet 103 is located on the axis of the air supply fan 100. The air outlet is located in the radial direction of the air supply fan 100.

[0049] In this embodiment, the air supply fan 100 is used to suck cold air from the air inlet 103 and send it out from the air outlet, so as to realize air supply into the refrigeration air duct.

[0050] It can be understood that the air supply fan 100 adopts the existing technology.

[0051] Optionally, the refrigeration equipment further includes an image acquisition device. The image acquisition device is disposed outside the air supply fan and is used to acquire an image of the area where the air supply fan 100 is located.

[0052] Optionally, the image acquisition device adopts a camera. The camera is installed outside the air supply fan 100, and the shooting direction of the camera is directly opposite to the air inlet 103 of the air supply fan 100.

[0053] Optionally, the refrigeration device further includes a processor and a memory storing program instructions, and the processor is configured to execute the control method of the refrigeration device when executing the program instructions.

[0054] Combined with Figure 3 As shown, an embodiment of the present disclosure provides a control method for a refrigeration device. The control method of the refrigeration device includes:

[0055] S301. When the air supply fan stops, the processor obtains the icing characteristic parameters of the air supply fan.

[0056] In the embodiment of the present disclosure, taking an image to obtain the icing characteristic parameters when the air supply fan 100 stops can improve the clarity of the image so that the image can accurately reflect the icing condition of the air supply fan 100.

[0057] In the embodiment of the present disclosure, by obtaining the icing characteristic parameters of the air supply fan 100 when the air supply fan 100 stops, the icing condition of the air supply fan 100 is obtained, providing a basis for judging the icing degree of the air supply fan 100 and whether ice melting treatment is required for the air supply fan 100.

[0058] S302. The processor obtains the operating mode of the refrigeration device.

[0059] In the embodiment of the present disclosure, by obtaining the operating mode of the refrigeration device, the operating mode of the refrigeration device is combined with the icing characteristic parameters, so as to analyze the icing characteristic parameters under different operating modes separately.

[0060] In the embodiment of the present disclosure, the operating modes of the refrigeration device include a defrosting mode and a refrigeration mode.

[0061] S303. The processor controls the heating element to operate according to the operating mode and the icing characteristic parameters.

[0062] In the embodiment of the present disclosure, by combining the operating mode of the refrigeration device and the icing condition of the air supply fan 100, the operation of the heating element 200 is controlled, realizing accurate and effective control of the operation of the heating element 200, improving the heating efficiency, and further improving the ice melting treatment efficiency of the air supply fan 100, so that the air supply fan 100 operates smoothly.

[0063] Combined with Figure 4 As shown, an embodiment of the present disclosure provides a control method for a refrigeration device. The control method of the refrigeration device includes:

[0064] S401. When the air supply fan stops, the processor obtains the image information of the air supply fan.

[0065] In this embodiment, when the air supply fan 100 is shut down, acquiring the image information of the air supply fan 100 can improve the clarity of the image and enable the image to accurately reflect the icing condition of the air supply fan 100.

[0066] S402. The processor determines the icing area of the air supply fan according to the image information.

[0067] In this embodiment, determining the icing area of the air supply fan according to the image information provides actual data for understanding the icing condition of the air supply fan 100 and determining the icing proportion.

[0068] S403. The processor determines the icing proportion according to the icing area and the total surface area of the air supply fan.

[0069] In this embodiment, the icing proportion can provide quantitative data for determining the icing condition of the air supply fan, so as to accurately judge whether the air supply fan 100 needs de-icing treatment.

[0070] S404. The processor acquires the operating mode of the refrigeration device.

[0071] S4051. When the operating mode is the refrigeration mode and the icing proportion is greater than or equal to the first threshold, the processor determines the first operating power and the first operating duration of the heating element.

[0072] S4052. The processor controls the heating element to operate at the first operating power for the first operating duration.

[0073] S4053. When the operating mode is the refrigeration mode and the icing proportion is less than the first threshold, the processor controls the heating element to remain in the off state.

[0074] In this embodiment, the operating mode is the refrigeration mode and the air supply fan 100 is in the shutdown state. When the icing proportion is greater than or equal to the first threshold, it indicates that the icing area on the surface of the air supply fan 100 is large and de-icing treatment is required. The air supply fan 100 is de-iced by controlling the heating element 200 to operate at the first operating power for the first operating duration. When the icing proportion is less than the first threshold, it indicates that there is no icing or the icing area on the surface of the air supply fan 100 is small and de-icing treatment is not required.

[0075] In this embodiment, by combining the refrigeration mode with the icing proportion, the accuracy of determining the icing condition on the surface of the air supply fan 100 can be improved, and then the accurate and effective control of the operation of the heating element 200 is achieved, which improves the efficiency and reduces the energy consumption.

[0076] Combined Figure 5 As shown in

[0077] S501. The processor determines that the operating mode is the cooling mode.

[0078] S502. The processor determines whether the ice formation ratio is greater than or equal to the first threshold.

[0079] In this embodiment, the first threshold is 40%.

[0080] S503. If the ice formation ratio is greater than or equal to the first threshold, the processor controls the heating element to operate at the first operating power for the first operating duration.

[0081] S504. If the ice formation ratio is less than the first threshold, the processor controls the heating element to remain in the off state.

[0082] In this embodiment, by combining the cooling mode with the ice formation ratio for analysis, accurate and effective control of the operation of the heating element 200 is achieved.

[0083] Optionally, step S401 includes: when the air supply fan stops, taking an image of the area where the air supply fan is located through a camera to obtain the image information of the air supply fan.

[0084] Combined Figure 2 As shown, in this embodiment, the camera is installed outside the air supply fan 100, and the shooting direction of the camera is directly opposite to the air inlet 103 of the air supply fan 100, so that the camera can take an image of the area where the air supply fan 100 is located. The image of the area where the air supply fan 100 is located includes the air supply fan 100 and its surrounding area. That is, the shooting area of the camera is the area where the air supply fan 100 is located. By setting the shooting direction of the camera directly opposite to the air inlet 103 of the air supply fan 100, the area of the fan blades 102 can be reflected in the image taken by the camera, improving the accuracy of obtaining the ice formation area.

[0085] Optionally, when the shooting direction of the camera is directly opposite to the air inlet 103 of the air supply fan 100, the actual area of the area where the air supply fan 100 is located and the total surface area of the air supply fan 100 are determined in advance.

[0086] Optionally, step S402 includes: inputting the image into an image recognition model trained based on a sample set. The sample set includes multiple sample images, and the sample images contain ice formation areas. The ice formation area in the image is recognized using the image recognition model. The ratio of the ice formation area in the image is calculated to obtain a ratio value. The product of the ratio value and the actual area of the area where the air supply fan is located is calculated to obtain the ice formation area of the air supply fan 100.

[0087] Optionally, step S403 includes: calculating the ice formation area / total surface area to obtain the ice formation ratio.

[0088] In some embodiments, during the process of controlling the operation of the heating element, the control method further includes: controlling the air supply fan to start and operate for a preset duration.

[0089] In this embodiment, during the operation of the heating element 200, the air supply fan 100 is controlled to start to shake off the defrosting ice water, preventing the defrosting ice water from freezing again after the heating element 200 stops heating, and improving the defrosting effect.

[0090] Optionally, the preset duration for which the air supply fan 100 operates is less than or equal to the first operation duration.

[0091] Exemplarily, the air supply fan 100 is a duty cycle speed control fan. When the operation mode of the refrigeration device is the refrigeration mode and the air supply fan 100 is shut down, if the ice formation ratio is greater than or equal to the first threshold, the heating element 200 is controlled to operate at the first operation power for the first operation duration (for example, 10 minutes). During the heating process of the heating element 200, for example, 5 minutes after the heating element 200 starts heating, the air supply fan 100 is controlled to start and rotate at a 50% duty cycle to shake off the defrosting ice water. After the heating element 200 and the air supply fan 100 work simultaneously for 5 minutes, both the heating element 200 and the air supply fan 100 stop working.

[0092] Combined with 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:

[0093] S601. When the air supply fan is shut down, the processor acquires the image information of the air supply fan.

[0094] S602. The processor determines the ice formation area of the air supply fan according to the image information.

[0095] S603. The processor determines the ice formation ratio according to the ice formation area and the total surface area of the air supply fan.

[0096] S604. The processor acquires the operation mode of the refrigeration device.

[0097] S6051. When the operation mode is the defrosting mode, the processor controls the heating element to operate at the second operation power for the second operation duration.

[0098] S6052. When the defrosting mode starts, the processor acquires the first ice formation ratio of the air supply fan.

[0099] S6053. When the defrosting mode ends, the processor acquires the second ice formation ratio of the air supply fan.

[0100] S6054. The processor controls the working state of the heating element according to the first ice formation ratio and the second ice formation ratio.

[0101] In an embodiment of the present disclosure, when the operating mode is the defrosting mode, the second operating power and the second operating duration of the heating element 200 are determined, and the heating element 200 is controlled to operate at the second operating power for the second operating duration. While defrosting the refrigeration device, the heating element 200 is used to defrost the air supply fan 100.

[0102] In an embodiment of the present disclosure, at the beginning of the defrosting mode, the first ice formation ratio of the air supply fan 100 is obtained to get the ice formation situation of the air supply fan 100 at the start of the defrosting mode. At the end of the defrosting mode, the second ice formation ratio of the air supply fan 100 is obtained to get the ice formation situation of the air supply fan 100 at the end of the defrosting mode. Based on the first ice formation ratio and the second ice formation ratio, the reduction degree of the ice formation area of the air supply fan 100 during the defrosting process is determined, and the working state of the heating element 200 is controlled by the reduction degree of the ice formation area of the air supply fan 100, so as to accurately and effectively control the operation of the heating element 200, and further improve the efficiency of defrosting the air supply fan 100.

[0103] In this embodiment, the implementation processes of steps S601 to S603 are the same as those of steps S401 to S403, and will not be described in detail herein.

[0104] In practical applications, the refrigeration device further includes a defrosting heating wire, a defrosting sensor, etc., which are used to defrost the evaporator when the operating mode is the defrosting mode. The defrosting process of the refrigeration device adopts the prior art and will not be described in detail herein.

[0105] It can be understood that the defrosting conditions for the refrigeration device to operate in the defrosting mode are not limited. For example, when the compressor has run for 8 hours cumulatively, or the compressor has run for 6 hours cumulatively and the door opening time has exceeded 10 minutes cumulatively, or the compressor has run continuously for more than 5 hours, the defrosting mode is executed.

[0106] It can be understood that the conditions for the refrigeration device 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 has been working continuously for 70 minutes, the defrosting mode is exited.

[0107] In some embodiments, the second operating duration is less than or equal to the defrosting duration of the defrosting mode.

[0108] In this embodiment, by setting the second operating duration to be less than or equal to the defrosting duration of the defrosting mode, the defrosting mode and the defrosting process of the air supply fan 100 start and end simultaneously. Or, the start time of the defrosting process of the air supply fan 100 is later than the start time of the defrosting mode, but the defrosting mode and the defrosting process of the air supply fan 100 end simultaneously. After the defrosting mode ends, the working state of the heating element 200 is controlled based on the first ice formation ratio and the second ice formation ratio to accurately and effectively control the heating element 200.

[0109] In some embodiments, the step of controlling the working state of the heating element 200 according to the first icing ratio and the second icing ratio includes: when the ratio of the second icing ratio to the first icing ratio is greater than or equal to a second threshold, controlling the heating element 200 to continue operating at a third operating power for a third operating duration; when the ratio of the second icing ratio to the first icing ratio is less than the second threshold, controlling the heating element 200 to stop operating.

[0110] In this embodiment, by controlling the operating state of the heating element 200 according to the relationship between the ratio of the second icing ratio to the first icing ratio and the second threshold, the operation of the heating element 200 can be effectively controlled, and the defrosting effect of the air supply fan 100 can be improved.

[0111] Exemplarily, as shown in combination with Figure 7 the flowchart of controlling the operation of the heating element 200 in the defrosting mode includes:

[0112] S701. When the defrosting condition is met, the processor controls the refrigeration device to start the defrosting mode.

[0113] S702. The processor controls the defrosting heating wire to work and simultaneously controls the heating element to operate at a second operating power.

[0114] S703. When the condition for exiting the defrosting mode is not met, the processor executes step S702. When the condition for exiting the defrosting mode is met, the processor executes step S704.

[0115] Among them, the condition for exiting the defrosting mode is that the temperature value collected by the defrosting sensor reaches 9°C or the defrosting heating wire works continuously for 70 minutes.

[0116] S704. The processor controls the refrigeration device to exit the defrosting mode.

[0117] S7051. The processor determines whether the ratio of the second icing ratio to the first icing ratio is greater than or equal to a second threshold.

[0118] S7052. If the ratio of the second icing ratio to the first icing ratio is greater than or equal to the second threshold, the processor controls the heating element to operate at a third operating power for a third operating duration.

[0119] S7053. If the ratio of the second icing ratio to the first icing ratio is less than or equal to the second threshold, the processor controls the heating element to stop operating.

[0120] In this example, when the operating mode of the refrigeration device is the defrosting mode, the defrosting heating wire works to defrost the evaporator. At the same time, the heating element 200 operates at the second operating power to de-ice the air supply fan 100. In this example, the condition for exiting the defrosting mode is that the temperature value collected by the defrosting sensor reaches 9 °C or the defrosting heating wire works continuously for 70 minutes. When the condition for exiting the defrosting mode is met, the refrigeration device exits the defrosting mode. At the same time, it is determined whether the ratio of the second icing ratio to the first icing ratio is greater than or equal to the second threshold. If the ratio of the second icing ratio to the first icing ratio is greater than or equal to the second threshold, the heating element 200 is controlled to continue operating at the third operating power for the third operating duration (for example, 10 minutes). That is to say, during the defrosting process, the reduction in the icing area of the air supply fan 100 is small, and the heating element 200 needs to continue operating to further de-ice the air supply fan 100. If the ratio of the second icing ratio to the first icing ratio is less than the second threshold, the heating element 200 is controlled to stop operating. That is to say, during the defrosting process, the reduction in the icing area of the air supply fan 100 is large, and there is no need to continue de-icing the air supply fan 100, reducing energy consumption. In this example, the second threshold is 50%.
