[0061] To enable any person skilled in the art to implement and use this application, the following description is provided. In this description, details are set forth for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0062] This application provides a defrosting method, apparatus, refrigerator, and computer-readable storage medium, which are described in detail below.

[0063] Please see Figure 1 , Figure 1 This is a schematic diagram of a defrosting system provided in an embodiment of this application. The defrosting system may include a refrigerator 100 and a storage device 200. The storage device 200 can store image data of the air vent received by a corresponding image sensor and can transmit the image data to the refrigerator 100. Figure 1 The refrigerator 100 can obtain the control program and image data corresponding to the defrosting method stored in the storage device 200 to execute the defrosting method in this application.

[0064] In this embodiment of the application, the storage device 200 may include, but is not limited to, mobile storage devices, cloud storage devices, local storage devices, etc.

[0065] In the embodiments of this application, the refrigerator 100 and the storage device 200 can communicate through any communication method, including but not limited to mobile communication based on the 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), and Worldwide Interoperability for Microwave Access (WiMAX), or computer network communication based on the TCP / IP Protocol Suite (TCP / IP) and User Datagram Protocol (UDP).

[0066] It should be noted that, Figure 1 The schematic diagram of the defrosting system shown is merely an example. The defrosting system and scenarios described in this application are intended to more clearly illustrate the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of defrosting systems and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0067] like Figure 2 As shown, Figure 2 This is a schematic flowchart of one embodiment of the defrosting method in this application. The method is applied to a refrigerator, which includes a freezing evaporator and a refrigeration evaporator, and specifically includes the following steps 201-202:

[0068] 201. If the refrigerator is confirmed to be in defrost mode, defrost the freezer evaporator.

[0069] In this embodiment, determining whether the refrigerator has entered defrost mode may include detecting the current temperature of the freezer or refrigerator compartment. If the current temperature of the freezer or refrigerator compartment is lower than a set temperature threshold, it can be determined that the current compartment is prone to frost buildup, and defrost mode can be entered at this time. Specifically, this embodiment does not limit the scope of the invention.

[0070] Once the refrigerator enters defrost mode, the internal heating device heats up, and a fan blows the heated air onto the evaporator to defrost it.

[0071] It should be noted that, in this embodiment, the refrigerator may include two food storage spaces: a freezer compartment and a refrigerator compartment. A freezer evaporator is disposed around the perimeter of the freezer compartment. When the condensing medium flows into the freezer evaporator, it absorbs heat and vaporizes inside, carrying away heat to cool the freezer compartment. Similarly, a refrigerator evaporator is disposed around the perimeter of the refrigerator compartment. When the condensing medium flows into the refrigerator evaporator, it absorbs heat and vaporizes inside, thus cooling the refrigerator compartment.

[0072] 202. If the freezer evaporator reaches the preset temperature threshold, open the refrigerator's air vent to allow the hot air generated during the defrosting process of the freezer evaporator to circulate to the refrigerator evaporator for defrosting.

[0073] In this embodiment, after defrosting the evaporator begins, the refrigeration damper can be opened when the temperature of the evaporator rises to a certain preset temperature, such as 0 degrees Celsius. The reason for opening the refrigeration damper is that when the temperature of the evaporator reaches 0 degrees Celsius, the frost on the evaporator may not be completely eliminated, but the temperature of the evaporator has definitely risen. Opening the refrigeration damper at this time allows warm air from around the evaporator to circulate to the evaporator, thereby accelerating the melting of the frost. It should be noted that in this embodiment, the refrigeration damper can be located between the refrigerator compartment and the freezer compartment. When the refrigeration damper is open, air exchange can occur between the refrigerator compartment and the freezer compartment.

[0074] The defrosting method provided in this application involves opening the refrigeration air damper between the freezer compartment and the refrigerator compartment after the temperature of the freezer evaporator rises to a certain level during defrosting. This allows the hot air generated during defrosting to circulate to the refrigerator evaporator, thereby accelerating the defrosting process and shortening the defrosting time of the refrigerator evaporator.

[0075] To better implement the embodiments of this application, in one embodiment, defrosting of the refrigerated evaporator includes:

[0076] Turn off the refrigerator compressor; turn off the refrigerator's freezer fan; turn off the refrigerator's air vents; turn on the refrigerator's heating element to defrost the freezer evaporator.

[0077] The above embodiments provide an implementation method for defrosting the freezer evaporator by activating the heating device. To further improve the defrosting efficiency of the freezer evaporator, the refrigerator compressor can be turned off during the defrosting process, preventing it from performing cooling operations. Simultaneously, turning off the refrigerator's refrigeration fan and refrigerator air damper prevents the refrigeration fan from blowing air heated by the heating device to other locations, such as the refrigerator compartment, thereby reducing the heating efficiency of the freezer evaporator. It should be noted that in this embodiment, turning off the refrigerator compressor, the refrigeration fan, and the refrigerator air damper can improve the defrosting efficiency of the freezer evaporator.

[0078] To better implement the embodiments of this application, in one embodiment, the refrigerator's refrigeration door is opened to allow hot air generated during defrosting of the freezer evaporator to circulate to the refrigeration evaporator for defrosting, including:

[0079] Open the refrigerator's cooling door and turn on the refrigerator's freezer fan to allow the hot air generated during the defrosting process of the freezer evaporator to circulate more quickly to the refrigerator evaporator, thus defrosting it.

[0080] The above embodiments provide a method for defrosting the refrigeration evaporator when only the refrigeration damper is opened. To further accelerate the melting of frost on the refrigeration evaporator, this embodiment can open the refrigeration fan and the refrigeration damper, allowing the residual heat from the refrigeration evaporator to reach the refrigeration evaporator more quickly, thereby accelerating the melting of frost on the refrigeration evaporator.

[0081] To better implement the embodiments of this application, in one embodiment of this application, after defrosting the refrigerated evaporator, the method further includes:

[0082] If the freezer evaporator reaches the freezer defrost exit temperature but the refrigerator evaporator does not, turn off the refrigerator's heating device and continue to monitor the current temperature of the refrigerator evaporator. If the current temperature of the refrigerator evaporator rises and reaches the refrigerator defrost exit temperature, close the refrigerator damper and turn off the freezer fan to end the defrost mode. If the current temperature of the refrigerator evaporator is not rising, turn off the freezer fan until the current temperature of the refrigerator evaporator rises and reaches the refrigerator defrost exit temperature, then close the refrigerator damper to end the defrost mode.

[0083] The above embodiments provide a method for defrosting by utilizing the waste heat of the refrigerated evaporator to heat the refrigerated evaporator. However, in reality, while the refrigerated evaporator is being heated for defrosting, the refrigerated evaporator is not being heated. Therefore, the refrigerated evaporator typically reaches its defrost exit temperature later than the refrigerated evaporator. Therefore, in this embodiment, if the refrigerated evaporator reaches its defrost exit temperature but the refrigerated evaporator has not, the heating device can be turned off first. At this time, since the refrigerated damper is already open; or the refrigeration fan is already on, the temperature of the refrigerated evaporator will gradually rise until it reaches its defrost exit temperature. At this point, the refrigeration fan and refrigerated damper can be turned off, and the defrosting mode can be ended. If the temperature of the refrigerated evaporator is not rising, it indicates that the waste heat of the refrigerated evaporator has cooled down after being blown by the refrigeration fan. In this case, the refrigeration fan can be turned off first, allowing the waste heat of the refrigerated evaporator to gradually heat the refrigerated evaporator. Afterwards, once the temperature of the refrigeration evaporator reaches the defrost exit temperature, close the refrigeration damper and exit the defrost mode.

[0084] To better implement the embodiments of this application, in one embodiment of this application, after defrosting the refrigerated evaporator, the method further includes:

[0085] If the freezer evaporator has not reached the freezer defrost exit temperature but the refrigerator evaporator has reached the refrigerator defrost exit temperature, close the refrigerator air damper and turn off the freezer fan; if the freezer evaporator has reached the freezer defrost exit temperature, turn off the refrigerator's heating device to end the defrost mode.

[0086] The above embodiment illustrates a scheme where the freezer evaporator reaches the defrost exit temperature first, followed by the refrigerator evaporator. However, a special case exists in reality: the user may leave the refrigerator door open and forget to close it. In this case, the refrigerator evaporator comes into contact with room temperature, and its defrosting time may be faster than that of the freezer evaporator. In other words, in this situation, the defrosting time of the freezer evaporator is longer than that of the refrigerator evaporator. If this situation occurs, the freezer fan and refrigerator damper can be turned off, keeping the hot air only around the freezer evaporator and preventing hot air from flowing into the refrigerator evaporator, thus accelerating the defrosting process of the freezer evaporator. When the temperature of the freezer evaporator reaches the defrost exit temperature, the heating device can be turned off and the defrost mode can be exited.

[0087] To better implement the embodiments of this application, in one embodiment of this application, the method further includes the following before defrosting the freeze evaporator:

[0088] Determine the frost condition of the freezer evaporator; based on the frost condition, determine whether the refrigerator should enter defrost mode.

[0089] The above embodiments provide an implementation method for determining whether a refrigerator has entered defrost mode based on temperature. This application also provides a scheme for determining whether a refrigerator has entered defrost mode based on time. For example, in this application embodiment, a timer can be set inside the refrigerator to record the total running time from startup to the current moment. If the total running time exceeds a set time threshold, it can be determined that the frost buildup on the freezer evaporator is severe, and defrost mode can be entered at this time. It should be noted that the time threshold in this application embodiment can be determined based on user feedback on refrigerator use and relevant actual data; the specific implementation of this application does not limit the time threshold.

[0090] To better implement the embodiments of this application, in one embodiment of this application, determining the frosting condition of the evaporator includes:

[0091] Acquire image data of the evaporator; determine the frosting condition of the evaporator based on the image data.

[0092] The above embodiments provide a solution for determining whether the freezer evaporator is frosted by means of time, temperature, etc. However, the freezer evaporator may not frost even at low temperatures or over a long period of time. In this case, if the refrigerator enters defrost mode, the cooling effect will decrease, and the food preservation ability will be reduced. Therefore, to avoid this situation, this application embodiment provides an image recognition method to determine whether the freezer evaporator is frosted. In this application embodiment, an image sensor can be installed at an appropriate location inside the refrigerator to obtain image data of the freezer evaporator.

[0093] It should be noted that, in the embodiments of this application, the image detection model used to detect whether the evaporator is frosted can be any type of image detection model that has been trained, and the specific embodiments of this application are not limited. For example, when the image detection model needs to detect whether the evaporator is icing or frosted, during the training phase, a large number of images of the evaporator with added icing or frost can be fed into the image detection model for training, so as to help the image detection model to identify the features of frost or ice on the evaporator, so that in the subsequent model application phase, the image detection model can detect whether the evaporator is icing or frosted based on the real-time acquired image data.

[0094] To better implement the defrosting method in the embodiments of this application, a defrosting device is also provided in the embodiments of this application. This device is applied to a refrigerator, which includes a freezing evaporator and a refrigeration evaporator, such as... Figure 3 As shown, the device 300 includes:

[0095] The first defrosting module 301 is used to defrost the freezer evaporator if it is determined that the refrigerator has entered the defrosting mode.

[0096] The second defrosting module 302 is used to open the refrigerator's cold air door if the freezer evaporator reaches a preset temperature threshold, so that the hot air generated during the defrosting of the freezer evaporator can circulate to the cold air evaporator to defrost it.

[0097] The defrosting device provided in this application, when defrosting the refrigeration evaporator through the first defrosting module 301, after the temperature of the refrigeration evaporator rises to a certain level, the second defrosting module 302 can open the refrigeration air damper between the freezer compartment and the refrigerator compartment, so that the hot air generated by defrosting can circulate to the refrigeration evaporator, thereby accelerating the defrosting process of the refrigeration evaporator and shortening the defrosting time of the refrigeration evaporator.
