Description

Technical Field

[0001] This application relates to the field of computer technology, and more specifically, to a method for defrosting a refrigerator, as well as a refrigerator, a computer-readable medium, and an electronic device. Background Technology

[0002] Refrigerators generate cooling capacity through the operation of a compressor; the higher the compressor speed, the greater the cooling capacity. High-speed compressor operation allows for rapid cooling, but the noise from continuous high-speed operation can disrupt the user's sleep. Low-speed compressor operation, while noise-free, results in slower cooling and may lead to slow temperature fluctuations in high ambient temperatures. Frost-free refrigerators require automatic defrosting at regular intervals; thanks to the defrosting heating element, the refrigerator compartment temperature significantly increases after defrosting.

[0003] In related technologies, when defrosting a refrigerator, pre-cooling is performed to lower the refrigerator's compartment temperature below the shutdown threshold. If the temperature is not well controlled, this method can easily lead to energy consumption or insufficient temperature, which in turn affects the refrigerator's normal cooling effect.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

In other instances, well-known methods, refrigerators, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0034] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0035] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0036] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0037] Figure 1 A flowchart of a refrigerator defrosting method according to an embodiment of this application is shown. This refrigerator defrosting method can be executed by a server, which may be... Figure 1 The server shown. (Refer to...) Figure 1 As shown, the defrosting method for the refrigerator includes at least steps S110 to S140, which are described in detail below:

[0038] In step S110, the current ambient temperature of the refrigerator and the cooling level set for the refrigerator are obtained.

[0039] During actual refrigerator operation, sudden high-speed operation and noise can disrupt normal rest. This high-speed operation is due to the periodic defrosting process in frost-free refrigerators. During defrosting with the heating element activated, heat radiation causes the temperature inside the refrigerator compartment to rise. Refrigerators generate cooling capacity through the compressor; the higher the compressor speed, the greater the cooling capacity. High-speed compressor operation allows for rapid cooling, but the continuous high-speed operation causes noise that can disrupt the user's sleep. Low-speed compressor operation, while noise-free, results in slower cooling and can lead to slow temperature recovery in high ambient temperatures. Frost-free refrigerators automatically defrost at regular intervals. Due to the defrosting heating element, the temperature inside the refrigerator compartment rises significantly after defrosting. Therefore, the first problem with defrosting is that the significant temperature rise can cause food to defrost or have a shorter storage time when using a higher setting or a medium setting in a warmer environment. When the temperature rises excessively due to defrosting, frost-free refrigerators often use high-speed compressor operation after defrosting to quickly lower the temperature. Therefore, the second problem with defrosting is increased noise. This is because the defrosting time of refrigerators is relatively random. When the defrosting occurs at night or when the user is resting, the sudden increase in noise generated by the compressor running at high speed can easily lead to user complaints.

[0040] To prevent food from thawing or having a shorter storage time in the defrost compartment, this embodiment proposes a pre-cooling control method for the defrost stage. The target pre-cooling temperature is determined based on the ambient temperature and the user-set temperature, thus mitigating the problem of food thawing or shortened storage time. This method also reduces the high speed the compressor is forced to operate at during the defrost recovery period, thereby reducing operating noise.

[0041] In one embodiment of this application, when determining to control the defrosting of the refrigerator, the current ambient temperature of the refrigerator and the cooling level set by the user are first obtained. The ambient temperature can be less than 25 degrees Celsius, greater than 35 degrees Celsius, etc., and the cooling level can be high, low, or medium, etc.

[0042] In step S120, based on the cooling setting and the corresponding temperature range of the ambient temperature, the target temperature that the refrigerator needs to lower during the pre-cooling process before performing the defrosting operation is determined.

[0043] In one embodiment of this application, after obtaining the cooling level and the current ambient temperature, the target temperature to be lowered during the pre-cooling process before the refrigerator performs the defrosting operation is determined based on the temperature range corresponding to the cooling level and the ambient temperature.

[0044] In one embodiment of this application, the process of determining the target temperature to be lowered during the pre-cooling process of the refrigerator before performing the defrosting operation, based on the cooling level and the temperature range corresponding to the ambient temperature in step S120, specifically includes:

[0045] If the temperature range is the first temperature range and the cooling setting is the first cooling setting, then the target temperature is determined as the first cooling temperature. If the temperature range is the second temperature range and the cooling setting is the second cooling setting, then the target temperature is determined as the first cooling temperature.

[0046] In this embodiment, the first temperature range corresponds to an ambient temperature lower than a first temperature threshold. For example, the first temperature threshold can be 25 degrees Celsius, and the first temperature range can include temperatures lower than 25 degrees Celsius.

[0047] In this embodiment, the ambient temperature corresponding to the second temperature range is greater than the ambient temperature corresponding to the first temperature range, or it can be a temperature greater than the first temperature threshold and less than or equal to the second temperature threshold. For example, if the second temperature threshold is 34 degrees Celsius, then the second temperature range is (25°C, 34°C).

[0048] In this embodiment, the first cooling level includes the set temperature corresponding to a temperature that is greater than or equal to the first level threshold and less than or equal to the second level threshold; for example, the first level threshold can be -15 degrees Celsius and the second level threshold can be -18 degrees Celsius, then the temperature range corresponding to the first cooling level is [-15℃, -18℃].

[0049] In this embodiment, the cooling temperature corresponding to the second cooling level is lower than the cooling temperature corresponding to the first cooling level. Specifically, it can include the temperature corresponding to a third level threshold that is greater than or equal to the third level threshold and less than or equal to the fourth level threshold. For example, the third level threshold can be -19 degrees Celsius, and the fourth level threshold can be -22 degrees Celsius. Then, the temperature range corresponding to the first cooling level is [-19℃, -22℃].

[0050] In this embodiment, the first cooling temperature t is determined based on the performance of the compressor, which is related to the performance of the refrigerator's own compressor.

[0051] Specifically, in step S120, based on the cooling setting and the corresponding temperature range of the ambient temperature, determining the target temperature to be lowered during the pre-cooling process before the refrigerator performs defrosting includes:

[0052] If the temperature range is the second temperature range and the cooling setting is the first cooling setting, then the target temperature is determined as the sum of the first cooling temperature and the second cooling temperature; wherein, the second cooling temperature is determined based on the ambient temperature.

[0053] In this embodiment, when the determined temperature range is the second temperature range and the cooling level is the first cooling level, the target temperature is determined as the sum of the first cooling temperature and the second cooling temperature. The second cooling temperature t1 is determined based on the ambient temperature. In this embodiment, the second cooling temperature t1 is determined based on the ambient temperature to regulate the pre-cooling process, which improves the intelligence of pre-cooling and reduces energy consumption.

[0054] Specifically, in step S120, based on the cooling setting and the corresponding temperature range of the ambient temperature, determining the target temperature to be lowered during the pre-cooling process before the refrigerator performs defrosting includes:

[0055] If the temperature range is the third temperature range and the cooling setting is the third cooling setting, then the target temperature is determined as the first cooling temperature.

[0056] In this embodiment, the third temperature range includes temperatures greater than a third temperature threshold, and the ambient temperature corresponding to the third temperature range is greater than the ambient temperature corresponding to the second temperature range. The third temperature threshold can be 35 degrees Celsius, and the third temperature range includes temperatures greater than 35 degrees Celsius.

[0057] In this embodiment, the cooling temperature corresponding to the third cooling level is lower than the cooling temperature corresponding to the second cooling level. The third cooling level is the level corresponding to the temperature when it is lower than the threshold of the fifth level. The threshold of the fifth level is -23 degrees Celsius.

[0058] If the temperature range is the third temperature range and the cooling setting is the second cooling setting, then the target temperature is determined as the sum of the first cooling temperature and the second cooling temperature. If the temperature range is the third temperature range and the cooling setting is the first cooling setting, then the target temperature is determined as the sum of the first cooling temperature and the third cooling temperature; wherein, the third cooling temperature is determined based on the ambient temperature.

[0059] In this embodiment, the third cooling temperature t2 is greater than the second cooling temperature t1, and both t1 and t2 are determined by the ambient temperature.

[0060] In the above embodiments, the first cooling setting, which is relatively low, indicates that the internal temperature of the refrigerator is higher compared to other settings. Furthermore, when the environment is in the third temperature zone, which is relatively high, the refrigerator is significantly affected by the external environment. Therefore, in this embodiment, the target temperature is obtained by summing the first and third cooling temperatures to lower the refrigerator temperature more significantly, thereby ensuring the freshness of the food.

[0061] In one embodiment of this application, a scenario where pre-cooling is not required is also included. Specifically, if the temperature range is the first temperature range and the cooling setting is the second or third cooling setting, pre-cooling is not performed, and the refrigerator is directly controlled to perform the defrosting operation. Alternatively, if the temperature range is the second temperature range and the cooling setting is the third cooling setting, pre-cooling is not performed, and the refrigerator is directly controlled to perform the defrosting operation.

[0062] In both of the above scenarios, the current ambient temperature is low, having minimal impact on the refrigerator itself; furthermore, the refrigerator's temperature setting is already low, meaning its internal temperature is already quite low, thus eliminating the need for pre-cooling. This method saves electricity consumed by the compressor during pre-cooling and reduces noise generated during refrigerator operation.

[0063] Based on this, in this embodiment, the corresponding pre-cooling method is determined according to the ambient temperature and the cooling level set by the user, as shown in Table 1:

[0064] Table 1

[0065]

[0066] In this implementation, the ambient temperature is divided into three levels: the first temperature range corresponds to low ambient temperature (T≤25℃), the second temperature range corresponds to medium ambient temperature (25℃<T≤34℃), and the third temperature range corresponds to high ambient temperature (T>35℃). Different products can be adjusted or refined according to actual conditions.

[0067] In this embodiment, the user-defined cooling settings are divided into three levels based on the user's actual usage characteristics: the first cooling setting corresponds to the light setting (-15℃ to -18℃), the second cooling setting corresponds to the medium setting (-19℃ to -22℃), and the third cooling setting corresponds to the dark setting (below -23℃). Different products can adjust or refine these settings according to their actual needs.

[0068] In step S130, based on the target temperature, the refrigerator compressor is controlled to perform pre-cooling.

[0069] In one embodiment of this application, after the target temperature is determined, the refrigerator compressor is controlled to pre-cool based on the target temperature. Specifically, during the pre-cooling process, if the compressor is in a stopped state, the compressor is started to pre-cool based on the target temperature; if the compressor is in a working state, the compressor continues to run to pre-cool based on the target temperature.

[0070] In step S140, after the pre-cooling process is completed, the refrigerator is controlled to perform a defrosting operation.

[0071] In one embodiment of this application, after the pre-cooling and cooling process is completed, the temperature inside the refrigerator body drops to a certain temperature, and then the refrigerator is controlled to perform a defrosting operation.

[0072] Figure 2 This is a flowchart of a precooling control provided in an embodiment of this application.

[0073] like Figure 2 As shown, after receiving the defrost command 210, the current ambient temperature T is first determined. When the product is in a low ambient temperature (T≤25℃), as follows... Figure 2 In setting 220, when the user-set setting is below the medium setting, the risk of thawing due to food convection with the compartment during the defrosting process is low due to low environmental load and low food storage temperature. Therefore, pre-cooling is not required during this stage. Similarly, at medium ambient temperatures, pre-cooling is also unnecessary when the user uses a high setting. This control reduces unnecessary cooling and lowers power consumption. When the product is at a low ambient temperature (T≤25℃), and the user-set setting is low, there is a risk of thawing due to food convection with the compartment during the defrosting process. Therefore, pre-cooling at t℃ is performed. Figure 2 The code 230 indicates that after the product receives the defrost signal, if the compressor is off, it starts to cool down by t℃; if the compressor is running, it continues to run at a higher temperature of t℃. Similarly, for medium ambient temperature (25℃ < T ≤ 34℃) at medium settings (-19℃ to -22℃) and high ambient temperature (T > 35℃) at deep settings (below -23℃), pre-cooling at t℃ is used. When the product is at a medium ambient temperature (25℃ < T ≤ 34℃) at a shallow setting (-15℃ to -18℃), due to the higher environmental load and the shallow setting, the risk of thawing due to food convection with the compartment is higher during the defrost end period. Therefore, pre-cooling at t+t1℃ is performed. If the compressor is off, it starts to cool down by t+t1℃; if the compressor is running, it continues to run at a higher temperature of t+t1℃. Similarly, for high ambient temperature (T > 35℃) at medium settings (-19℃ to -22℃), pre-cooling at t+t1℃ is used. When the product is at a high ambient temperature (T > 35℃) and a shallow setting (-15℃ to -18℃), due to the high environmental load and the user's shallow setting, the risk of food thawing due to convection between the food and the compartment is high during the defrosting process. Therefore, pre-cooling is performed at t+t2℃. If the compressor is off, it is started to lower the temperature by t+t2℃; if the compressor is running, it continues to pull the temperature by t+t2℃. After pre-cooling is complete, the refrigerator is controlled to perform the defrosting operation 240.
