[0002] Temperature control is a crucial aspect of modern refrigeration equipment design, directly impacting its cooling efficiency and food preservation quality. Currently, considering that moisture condenses into frost on the evaporator surface after a period of operation, affecting heat exchange, defrosting functions are typically added to refrigeration systems to ensure reliability. However, current defrosting methods suffer from high energy consumption, uneven defrosting processes, and low efficiency, negatively affecting the overall performance of the refrigeration equipment.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0065] The defrosting control method, defrosting control device, electronic device, and readable storage medium for storage devices provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.
[0066] The defrosting control method for storage equipment can be applied to the terminal, and can be executed by the hardware or software in the terminal.
[0067] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).
[0068] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.
[0069] The defrosting control method for storage devices provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the defrosting control method for the storage device. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The defrosting control method for storage devices provided in this application embodiment will be described below using an electronic device as the execution subject as an example.
[0070] like Figure 1 As shown, the defrosting control method for the storage device includes steps 110, 120, and 130.
[0071] Step 110: Obtain the number of times compressor 10 is started (n) between the end of the (i-2)th defrost and the start of the (i-1)th defrost. i-2 The number of times compressor 10 is started between the end of the (i-1)th defrost and the start of the i-th defrost. i-1 And the duration T of the (i-1)th defrost. i-1 .
[0072] It should be noted that storage equipment can be understood in a broad sense as refrigeration and storage equipment, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. Storage equipment has diverse structural forms and a wide range of applications. As a specific example, this application embodiment uses a vending freezer as an illustration, which is used to sell frozen goods, such as ice cream and ice cubes.
[0073] It is understandable that this is achieved by obtaining the number of times compressor 10 is started, n. i-2 and number of times the device is powered on n i-1 The operating frequency of compressor 10 and the efficiency of the previous defrost can be determined by obtaining the duration of the previous defrost cycle and the duration of the previous defrost cycle. This allows for a better understanding of the current operating status of the storage equipment and the rate of frost accumulation. It should be noted that in other embodiments, the number of times compressor 10 stops between the end of the (i-2)th defrost cycle and the start of the (i-1)th defrost cycle, as well as the number of times compressor 10 stops between the end of the (i-1)th defrost cycle and the start of the ith defrost cycle, can be used to indirectly obtain n. i-2 and n i-1 This embodiment does not impose specific limitations on this.
[0074] It should be noted that the duration of the first defrost and the duration of the second defrost are preset, i.e., i≥3, and i is a natural number.
[0075] Step 120: Based on the number of power-on attempts (n) i-2 Number of times the device is powered on (n) i-1And the duration T of the (i-1)th defrost. i-1 Determine the duration T of the i-th defrost. i .
[0076] Understandably, the duration of the current defrost is dynamically adjusted based on the number of times the compressor is turned on between two consecutive defrost cycles and the duration of the previous defrost cycle. This takes into account that the actual operating conditions of the storage equipment (such as the frequency of door opening and closing, the temperature and humidity inside and outside the room, and the load of items contained in the room) will affect the start-up and shutdown frequency of the compressor 10. Therefore, the defrost duration is flexibly adjusted according to the start-up and shutdown frequency of the compressor 10 to avoid the problem of increased energy consumption due to excessively long defrost time or poor defrost effect due to excessively short defrost time.
[0077] Step 130: Once the (i-1)th defrosting cycle has begun, proceed according to the duration T. i Perform the i-th defrost.
[0078] Understandably, dynamically adjusting the defrosting duration based on the number of times the machine is turned on between two consecutive defrost cycles and the duration of the previous defrost cycle not only ensures the efficiency and effectiveness of each defrost cycle but also reduces unnecessary energy consumption, improves the overall performance of the storage equipment, and extends the service life of the storage equipment.
[0079] According to the defrosting control of the storage equipment provided in the embodiments of this application, by dynamically adjusting the defrosting time each time, not only can the defrosting efficiency be improved, but also the defrosting energy consumption can be reduced, thereby improving the overall performance and adaptability of the storage equipment.
[0080] In some embodiments, step 120 is based on the number of power-on cycles n i-2 Number of times the device is powered on (n) i-1 And the duration T of the (i-1)th defrost. i-1 Determine the duration T of the i-th defrost. i ,include:
[0081] Step 121: Obtain the number of power-on attempts, n. i-1 and number of times the device is powered on n i-2 The difference between them;
[0082] Step 1211: If the difference is greater than the first threshold, the duration T is... i Equal to duration T i-1 Add a preset compensation duration;
[0083] Step 1212: When the difference equals the first threshold, the duration T is... i Equal to duration T i-1 ;
[0084] Step 1213: If the difference is less than the first threshold, the duration T is...i Equal to duration T i-1 Subtract the preset compensation duration.
[0085] It should be noted that △n=n i-1 -n i-2 That is, when Δn is greater than the first threshold, it means that compared to the period from the end of the (i-2)th defrost to the start of the (i-1)th defrost, the compressor 10 is started more frequently during the period from the end of the (i-1)th defrost to the start of the ith defrost, which means that the frost layer accumulates faster, thus causing T to... i =T i-1+ Tt, thus extending the duration of the i-th defrost based on the duration of the (i-1)-th defrost, to ensure the defrosting effect.
[0086] Similarly, when Δn equals the first threshold, it means that compared to the period from the end of the (i-2)th defrost to the start of the (i-1)th defrost, the number of times compressor 10 is started increases moderately during the period from the end of the (i-1)th defrost to the start of the ith defrost, indicating that the frost accumulation rate is relatively stable. Therefore, T... i =T i-1 This ensures that the duration of the i-th defrost is the same as that of the (i-1)-th defrost, thus guaranteeing the defrosting effect.
[0087] Similarly, when Δn is less than the first threshold, it means that compared to the period from the end of the (i-2)th defrost to the start of the (i-1)th defrost, the number of times compressor 10 is started increases less during the period from the end of the (i-1)th defrost to the start of the ith defrost, which means that the frost accumulation rate is relatively slower, thus causing T to... i =T i-1 -Tt, thereby shortening the duration of the i-th defrost based on the duration of the i-1th defrost, so as to ensure the defrosting effect while saving energy.
[0088] It is understandable that dynamically adjusting the defrosting duration by varying the start-stop frequency of the compressor 10 ensures sufficient defrosting while avoiding unnecessary energy waste. It should be noted that the specific values of the first threshold and the preset compensation duration can be designed according to actual needs; this embodiment does not impose specific limitations on them. For example, the first threshold is equal to 0.
[0089] In some embodiments, such as Figure 2 As shown, the defrosting system of the storage equipment includes a refrigeration circuit, which includes a compressor 10, a condenser 20, a dryer filter 30, a capillary tube 40, and an evaporator 50 connected in sequence.
[0090] Understandably, the refrigerant is compressed into a high-temperature, high-pressure gaseous state by the compressor 10 and then enters the condenser 20 to be cooled into a liquid state. The liquid refrigerant passes through the dryer filter 30 to remove impurities and moisture and then enters the capillary tube 40 for throttling and pressure reduction. The low-temperature, low-pressure refrigerant enters the evaporator 50, absorbs heat, vaporizes into a gaseous state, and flows into the compressor 10, thereby achieving the cooling of the room.
[0091] In some embodiments, such as Figure 2 As shown, multiple condensers 20 are provided to improve refrigeration efficiency. For example, four condensers 20 are provided.
[0092] In some embodiments, such as Figure 2 As shown, the defrosting system also includes a bypass branch and a heating element. A defrost valve 60 is provided on the bypass branch, located between the compressor 10 and the evaporator 50. The heating element is used to heat at least one of the compartments formed by the evaporator 50 and the storage device. The defrost valve 60 includes, but is not limited to, a solenoid valve. The heating element includes, but is not limited to, a heating wire.
[0093] Understandably, on the one hand, the bypass branch is connected to the refrigeration circuit. That is, when the defrost valve 60 is open, the high-temperature, high-pressure gaseous refrigerant flowing from the compressor 10 can directly flow into the evaporator 50 through the defrost valve 60 to heat the surface of the evaporator 50 and melt the defrost layer. This utilizes the existing high-temperature refrigerant in the refrigeration circuit to heat the evaporator 50, further reducing energy consumption. On the other hand, by using a heating element to heat the evaporator 50 or the compartment, the space within the compartment can also be heated, accelerating the melting of the frost layer and improving the defrosting effect. In this embodiment, the heating element is installed inside the compartment. Of course, in other embodiments, the heating element can also be placed close to the evaporator 50; this embodiment does not impose specific limitations on this.
[0094] In some embodiments, such as Figure 2 As shown, a silencer 70 is provided between the compressor 10 and the defrost valve 60 to reduce the noise and pressure pulsation generated during the operation of the compressor 10, while providing additional protection during the defrosting process.
[0095] In some embodiments, performing the i-th defrost in step 130 includes:
[0096] Step 131: Control the heating element to open;
[0097] Step 132: With compressor 10 already stopped, obtain the actual downtime of compressor 10;
[0098] Step 133: If the actual downtime is not less than the first preset time, control the compressor 10 to start and control the defrost valve 60 to open.
[0099] Understandably, on the one hand, by installing the heating element inside the storage unit to heat the air inside the unit, the temperature around the evaporator 50 is increased, accelerating the melting of the frost layer and creating favorable conditions for the defrosting process. On the other hand, when the compressor 10 has stopped, the actual shutdown time of the compressor 10 is obtained to ensure that the compressor 10 has sufficient shutdown time before restarting, thus avoiding the impact of frequent start-stop cycles on the lifespan of the compressor 10. At the same time, by ensuring that the actual shutdown time of the compressor 10 is not less than a first preset time before restarting and opening the defrost valve 60, the overall pressure of the defrosting system can be increased, reducing the possibility of insufficient pressure during the defrosting process, improving defrosting efficiency while reducing energy consumption, and extending the service life of the storage unit.
[0100] It should be noted that the first preset duration can be designed according to actual needs, and this embodiment does not impose specific restrictions on it.
[0101] In some embodiments, step 132, after obtaining the actual shutdown duration of the compressor 10 when the compressor 10 has already stopped, further includes:
[0102] Step 1321: If the compressor 10 is not stopped, control the compressor 10 to stop for a first preset time.
[0103] Understandably, if the compressor 10 has not yet stopped, or if the shutdown time of the compressor 10 is less than the first preset duration, the compressor 10 is forcibly shut down until the shutdown time reaches the first preset duration, and then the compressor 10 is turned on and the defrost valve 60 is opened. This dynamically controls the shutdown time of the compressor 10 during each defrost process, creating stable defrost system pressure conditions, ensuring the efficiency and stability of the defrost process, and protecting the service life of the compressor 10.
[0104] In some embodiments, the time between controlling the compressor 10 to start and the defrost valve 60 to open in step 133 is equal to a second preset time.
[0105] Understandably, if the actual downtime of compressor 10 is not less than the first preset time, the defrost valve 60 will be opened only after the compressor 10 has been started for a second preset time. Considering that compressor 10 needs time to build up pressure in the defrost system after starting, setting a second preset time ensures that the defrost system pressure reaches a stable level, improving the efficiency and stability of the defrost process and optimizing defrost efficiency. Simultaneously, by gradually starting compressor 10 and defrost valve 60, the impact of pressure fluctuations on compressor 10, defrost valve 60, or evaporator 50 can be reduced, extending the service life of the defrost system.
[0106] It should be noted that the second preset duration can be designed according to actual needs, and this embodiment does not impose specific restrictions on it.
[0107] In some embodiments, step 133, which involves controlling the compressor 10 to start and controlling the defrost valve 60 to open, further includes:
[0108] Step 134: Close the defrost valve 60 and stop the compressor 10;
[0109] Step 135: After the compressor 10 has been stopped for a third preset time, control the compressor 10 to start and control the heating element to shut down.
[0110] Understandably, considering that the frost on the surface of the evaporator 50 melts and forms liquid water during the defrosting process, stopping the compressor 10 for a third preset time ensures that the melted frost water has enough time to drip off and drain out of the storage equipment before refrigeration begins, preventing moisture from remaining in the evaporator 50 or the compartment and refreezing, thus improving the reliability of the storage equipment. On the other hand, heating by the heating element can increase the temperature inside the compartment and reduce the rate of frost formation.
[0111] In some embodiments, the first preset duration is to ensure that the compressor 10 has sufficient downtime to protect its lifespan and stabilize system pressure. The third preset duration focuses on ensuring that defrost water is discharged and is shorter than the first preset duration, as its main task is to wait for the melted defrost water to completely drain from the storage device. The second preset duration is to ensure that the system pressure is stable and is shorter than the third preset duration. Of course, in other embodiments, the third preset duration can be designed according to actual needs, and this embodiment does not impose specific limitations on it.
[0112] For example, such as Figure 3 As shown, Figure 3Three different defrosting processes are provided, where C13 refers to a time shorter than the preset duration, D13 refers to the second preset duration, DD refers to the third preset duration, and t refers to the actual downtime of the compressor 10 during the current defrosting process. Before entering the first defrosting process, the compressor 10 is not yet stopped. Therefore, after controlling the heating element to open and stopping the compressor 10 (C13), the compressor 10 is controlled to open (D13), and then the defrost valve 60 is opened. After the defrost valve 60 has been open for a certain period, it is closed, and the compressor 10 is stopped (DD). Finally, the heating element is controlled to close, and the compressor 10 is controlled to start cooling to complete the defrosting process. Before entering the second defrost process, compressor 10 has already stopped, and the actual stop time is longer than C13. Therefore, the heating element is turned on, and compressor 10 is turned on at D13 before defrosting valve 60 is opened. After defrosting valve 60 has been open for a period of time, it is closed, and compressor 10 is stopped at D13. Then, the heating element is turned off, and compressor 10 is turned on to enter refrigeration mode, thus completing this defrost cycle. Before entering the third defrost process, compressor 10 has already stopped, and the actual stop time is shorter than C13. Therefore, the heating element is turned on, and compressor 10 continues to be stopped until compressor 10 stops at C13. Then, compressor 10 is turned on at D13 before defrosting valve 60 is opened. After defrosting valve 60 has been open for a period of time, it is closed, and compressor 10 is stopped at D13. Then, the heating element is turned off, and compressor 10 is turned on to enter refrigeration mode, thus completing this defrost cycle.
[0113] In some embodiments, the time between controlling the defrost valve 60 to open and controlling the defrost valve 60 to close is not greater than the duration T. i .
[0114] It is understandable that the time between the opening of defrost valve 60 in step 133 and the closing of defrost valve 60 in step 134 is no greater than the duration T. i This ensures the defrosting process is long enough to melt the defrost layer, but not too long to avoid wasting energy. It also reduces the risk of the evaporator overheating and melting due to excessively long defrosting times. It should be noted that the duration T... i The defrosting time should not exceed the maximum defrosting time. The specific value of the maximum defrosting time can be designed according to actual needs, and this embodiment does not impose specific restrictions on it.
[0115] In some embodiments, the method further includes the following steps after controlling the defrost valve 60 to open and before controlling the defrost valve 60 to close:
[0116] The real-time temperature S of the room is obtained by a temperature sensor, and the real-time temperature S is not greater than the first preset temperature S1.
[0117] It is understood that the real-time temperature S of the compartment must be less than or equal to S1 between the opening of the defrost valve 60 in step 133 and the closing of the defrost valve 60 in step 134, to ensure that the temperature inside the compartment does not get too high during the defrosting process and to reduce the possibility of melting. It should be noted that the specific value of the first preset temperature S1 can be designed according to actual needs, and this embodiment does not impose specific restrictions on it.
[0118] In some embodiments, after each defrosting cycle, if the real-time temperature S is greater than a second preset temperature S2, the thermostat issues a warning signal so that the system and the user can take timely action, enhancing the safety of the storage equipment and the user experience. It should be noted that the specific value of the second preset temperature S2 can be designed according to actual needs, and this embodiment does not impose specific limitations on it. For example, S2 = -18℃.
[0119] In some embodiments, if the temperature sensor is unable to detect the temperature of the room due to malfunction or other reasons, the real-time temperature S will always be displayed as S1 by default in order to trigger the defrosting requirement and perform the defrosting based on the duration of the last defrosting time.
[0120] In some embodiments, the defrosting control method further includes:
[0121] After the storage device is powered on for the first time, if it is determined that the duration of each of the k consecutive defrosting cycles is less than the target duration dn1, the defrosting pause mode is activated. In the defrosting pause mode, the next defrosting cycle is stopped; where k is a positive integer. For example, k = 3.
[0122] It is understandable that if the duration of multiple consecutive defrost cycles is less than the target duration dn1, it indicates that the current defrosting demand is low, and the next planned defrost cycle can be skipped to save energy and ensure the flexibility and efficiency of system operation. It should be noted that the specific value of the target duration dn1 can be designed according to actual needs, and this embodiment does not impose specific restrictions on it.
[0123] In this embodiment, dn1 = dn × dP1 / 1000, where dp1 refers to the maximum defrosting time (in minutes); dn refers to the nominal defrosting duration without defrosting, and the value of dn ranges from 0 to 1000. It should be noted that the specific value of dn can be designed according to actual needs, and this embodiment does not impose specific restrictions on it.
[0124] In some embodiments, if it is determined that the duration of each of k consecutive defrost cycles is less than the target duration dn1, a defrost pause mode is activated. In the defrost pause mode, the next defrost cycle is stopped, including:
[0125] If the duration of each defrost from the jth to the j+k-1th time is less than the target duration dn1, activate the pause defrost mode.
[0126] In the pause defrost mode, stop the (j+k)th defrost cycle, where j≥c and c is a positive integer;
[0127] If the duration of any defrosting operation from j to j+k-1 is not less than the target duration dn1, exit the pause defrosting mode.
[0128] Understandably, after the storage device is first powered on, it will perform defrosting c times to ensure stable operation. Then, starting from the j-th defrost, the duration of k consecutive defrost cycles will be monitored. If the duration of each of the k defrost cycles is less than the target duration dn1, then the (j+k)th defrost cycle will not be executed, and the (j+k+1)th defrost cycle will be executed instead. If the duration of the jth defrost cycle is greater than or equal to the target duration dn1, then the paused defrost mode will be exited so that the cth defrost cycle can be completed again, and the duration of the k consecutive defrost cycles will be monitored repeatedly. Similarly, if the duration of the (j+1)th defrost cycle is greater than or equal to the target duration dn1, then the paused defrost mode will be exited so that the cth defrost cycle can be completed again, and the duration of the k consecutive defrost cycles will be monitored repeatedly.
[0129] For example, such as Figure 4 As shown, it illustrates a strategy table for activating and pausing the defrost mode, where c=8 and k=3. This means that if the duration of the 8th, 9th, and 10th defrost cycles is less than the target duration, the planned 11th defrost cycle is stopped, and the 12th defrost cycle is executed. It should be noted that since the 11th defrost cycle is not executed, the duration of the 12th defrost cycle is determined based on the number of times compressor 10 is started between the end of the 9th defrost cycle and the start of the 10th defrost cycle, the number of times compressor 10 is started between the end of the 10th defrost cycle and the start of the 12th defrost cycle, and the duration of the 10th defrost cycle.
[0130] In some embodiments, in the paused defrost mode, if it is determined that the duration of the (j+k+1)th defrost is less than the target duration dn1, the defrost cycles from the (j+k+2)th to the (j+k+2+p)th defrost are stopped, where p is a positive integer;
[0131] If the duration of the (j+k+1)th defrost is determined to be no less than the target duration dn1, exit the pause defrost mode. For example, p = 1.
[0132] Understandably, after the storage device is first powered on, it will perform c defrosting cycles to ensure stable operation. Then, starting from the j-th defrost cycle, the duration of k consecutive defrost cycles is monitored. If the duration of all k defrost cycles is less than the target duration dn1, the (j+k)-th defrost cycle is skipped, and the (j+k+1)-th defrost cycle is executed instead. If the duration of the (j+k+1)-th defrost cycle is less than the target duration dn1, the (j+k+2)-(j+k+2+p)-th defrost cycles are skipped, and the (j+k+2+p+1)-th defrost cycle is executed instead. If the duration of the (j+k+1)-th defrost cycle is greater than or equal to the target duration dn1, the defrost pause mode is exited so that c defrost cycles can be performed again, and the duration of the k consecutive defrost cycles is monitored repeatedly.
[0133] For example, such as Figure 4 As shown, where c=8, k=3, p=1, that is, if the duration of the 8th, 9th, and 10th defrosts is less than the target duration, the originally planned 11th defrost is stopped, and the 12th defrost is executed. If the duration of the 12th defrost is less than the target duration, the originally planned 13th and 14th defrosts are stopped, and the 15th defrost is executed. It should be noted that since the 13th and 14th defrosts were not executed, the duration of the 15th defrost is determined based on the number of times compressor 10 was started between the end of the 10th defrost and the start of the 12th defrost, the number of times compressor 10 was started between the end of the 12th defrost and the start of the 15th defrost, and the duration of the 12th defrost.
[0134] In some embodiments, in the paused defrost mode, if it is determined that the duration of the defrost of the j+k+2+p+1th time is less than the target duration dn1, the defrosts from the j+k+2+p+2th time to the j+k+2+p+qth time are stopped, where q is a positive integer;
[0135] After performing defrost cycles j+k+2+p+1 to j+k+2+p+q, exit the paused defrost mode. For example, q = 2.
[0136] Understandably, after the storage device is first powered on, it will perform defrosting c times to ensure stable operation. Then, starting from the j-th defrost, the duration of k consecutive defrost cycles will be monitored. If the duration of each of the k defrost cycles is less than the target duration dn1, then the (j+k)th defrost cycle will not be executed, and the (j+k+1)th defrost cycle will be executed instead. If the duration of the (j+k+1)th defrost cycle is less than the target duration dn1, then the (j+k+2)th to (j+k+2+p)th defrost cycles will not be executed, and the (j+k+2+p+1)th defrost cycle will be executed instead. If the duration of the (j+k+2+p+1)th defrost cycle is less than the target duration dn1, then the (j+k+p+4)th to (j+k+p+4+q)th defrost cycles will not be executed, and the (j+k+p+4+q+1)th defrost cycle will be executed instead, and the paused defrost mode will be exited. If the duration of the (j+k+2+p+1)th defrost cycle is greater than or equal to the target duration dn1, the paused defrost mode will be exited so that the (c)th defrost cycle can be completed again, and the duration of the k consecutive defrost cycles will be monitored repeatedly.
[0137] For example, such as Figure 4 As shown, where c=8, k=3, p=1, q=2, that is, if the duration of the 8th, 9th, and 10th defrosts is less than the target duration, the planned 11th defrost is stopped and the 12th defrost is executed. If the duration of the 12th defrost is less than the target duration, the planned 13th and 14th defrosts are stopped and the 15th defrost is executed. If the duration of the 15th defrost is less than the target duration, the planned 16th, 17th, and 18th defrosts are stopped and the 19th defrost is executed. The duration of the 19th, 20th, and 21st defrosts is compared with the target duration dn1 to determine whether to re-enter the defrost mode. It should be noted that since the 16th, 17th, and 18th defrost cycles were not performed, the duration of the 19th defrost cycle was determined based on the number of times the compressor 10 was started between the end of the 12th defrost cycle and the start of the 15th defrost cycle, the number of times the compressor 10 was started between the end of the 15th defrost cycle and the start of the 19th defrost cycle, and the duration of the 15th defrost cycle.
[0138] In some embodiments, the defrosting control method for storage devices further includes:
[0139] Within a preset time period, if the duration of each of the m consecutive defrost cycles gradually increases, and the duration of each defrost cycle from the 1st to the 1+m-1th cycle is greater than the target duration dn1, then a supplementary defrost mode is executed; where m is a positive integer.
[0140] It is understandable that if the duration of each of the m consecutive defrosting cycles within a preset time period gradually increases, and the duration of each defrosting cycle from the 1st to the 1+m-1th cycle is greater than the target duration dn1, it indicates that there may be a thick frost layer or insufficient defrosting. Therefore, by adding a supplementary defrosting mode, the overall defrosting effect is enhanced, thus optimizing energy saving and equipment lifespan. For example, m = 3.
[0141] In some embodiments, the preset time period is during the daytime period, and the corrective defrosting mode is executed during the nighttime period to reduce the impact on normal daytime operation and user experience, while optimizing the overall performance of the storage equipment.
[0142] In some embodiments, in the corrective defrosting mode, the duration of the corrective defrosting mode is equal to the duration of defrosting closest to the moment the corrective defrosting mode is executed, plus the correction duration t, to improve the defrosting effect. It should be noted that the specific value of t can be designed according to actual needs, and this embodiment does not impose specific limitations on it.
[0143] In some embodiments, in the corrective defrosting mode, the real-time temperature S is less than the first preset temperature S1 plus the third preset temperature S3 to improve the defrosting effect. It should be noted that the specific value of S3 can be designed according to actual needs, and this embodiment does not impose specific limitations on it.
[0144] In some embodiments, if the duration of each of the m consecutive defrost cycles gradually increases within a preset time period, and the duration of each defrost cycle from the 1st to the (1+m-1)th cycle is greater than the target duration dn1, and if the (r+1)th defrost cycle occurs exactly at midnight (0:00 AM) after the 1st defrost cycle, then the (r+1)th defrost cycle is paused and a corrective defrost mode is executed. Where r ≥ 1+m-1.
[0145] In some embodiments, if the duration of each of the m consecutive defrost cycles gradually increases within a preset time period, and the duration of each defrost cycle from the 1st to the (1+m-1)th cycle is greater than the target duration dn1, and the time of the (r+1)th defrost cycle after the 1st defrost cycle is not midnight (0:00 AM), and the time between the 1st defrost cycle and midnight is less than P / 2 (where P is the time between the 1st defrost cycle and the (r+1)th defrost cycle), then the (r+1)th defrost cycle is executed first, followed by the corrective defrost mode, and the time between the time of the corrective defrost mode and the (r+1)th defrost cycle is equal to P / 2. Of course, in other embodiments, midnight can be replaced with other times; this embodiment does not impose specific limitations on this.
[0146] The defrosting control method for storage devices provided in this application can be executed by a defrosting control device for the storage device. This application uses the example of a defrosting control device executing the defrosting control method for a storage device to illustrate the defrosting control device for the storage device provided in this application.
[0147] This application also provides a defrosting control device for storage equipment.
[0148] like Figure 5 As shown, the defrosting control device of the storage equipment includes an acquisition module 210, a processing module 220, and an execution module 230. The acquisition module 210 is used to acquire the number of times the compressor 10 is started n between the end of the (i-2)th defrost and the start of the (i-1)th defrost. i-2 The number of times compressor 10 is started between the end of the (i-1)th defrost and the start of the i-th defrost. i-1 And the duration T of the (i-1)th defrost. i-1 Processing module 220 is used to process data based on the number of power-on cycles n. i-2 Number of times the device is powered on (n) i-1 And the duration T of the (i-1)th defrost. i-1 Determine the duration T of the i-th defrost. i The execution module 230 is used to, upon determining that the (i-1)th defrosting session has begun, determine the duration T. i Perform the i-th defrost.
[0149] The defrosting control device for storage equipment provided in the embodiments of this application can not only improve defrosting efficiency and reduce defrosting energy consumption by dynamically adjusting the defrosting time each time, but also improve the overall performance and adaptability of the storage equipment.
[0150] In some embodiments, the processing module 220 is used to process based on the number of power-on cycles n i-2 Number of times the device is powered on (n) i-1 And the duration T of the (i-1)th defrost. i-1 Determine the duration T of the i-th defrost. i This includes the following steps:
[0151] Get the number of times the device is powered on (n) i-1 and number of times the device is powered on n i-2 The difference between them;
[0152] If the difference is greater than the first threshold, the duration T is... i Equal to duration T i-1 Add a preset compensation duration;
[0153] When the difference equals the first threshold, the duration T is... i Equal to duration T i-1 ;
[0154] If the difference is less than the first threshold, the duration T is... i Equal to duration T i-1 Subtract the preset compensation duration.
[0155] In some embodiments, the execution module 230 is used to perform the i-th defrosting, including the following steps:
[0156] Control the heating element to open;
[0157] If compressor 10 has already stopped, obtain the actual downtime of compressor 10;
[0158] If the actual downtime is not less than the first preset time, control the compressor 10 to start and control the defrost valve 60 to open.
[0159] In some embodiments, the execution module 230 is used to control the compressor 10 to start and control the defrost valve 60 to open, and then further includes:
[0160] Control the defrost valve 60 to close and control the compressor 10 to stop;
[0161] After the compressor 10 has been shut down for a third preset period of time, the compressor 10 is turned on and the heating element is turned off.
[0162] In some embodiments, the execution module 230 further includes the following functions after controlling the defrost valve 60 to open and before controlling the defrost valve 60 to close:
[0163] The real-time temperature S of the room is obtained by a temperature sensor, and the real-time temperature S is not greater than the first preset temperature S1.
[0164] In some embodiments, the execution module 230 is further configured to, after the storage device is powered on for the first time, if it is determined that the duration of each of the k consecutive defrosting operations is less than the target duration dn1, activate the pause defrosting mode and stop the next defrosting operation in the pause defrosting mode; where k is a positive integer.
[0165] In some embodiments, the execution module 230 is configured to activate a pause defrosting mode if it determines that the duration of each of the k consecutive defrosting cycles is less than the target duration dn1. In the pause defrosting mode, the next defrosting cycle is stopped, including the following steps:
[0166] If the duration of each defrost from the jth to the j+k-1th time is less than the target duration dn1, activate the pause defrost mode.
[0167] In the pause defrost mode, stop the (j+k)th defrost cycle, where j≥c and c is a positive integer;
[0168] If the duration of any defrosting operation from j to j+k-1 is not less than the target duration dn1, exit the pause defrosting mode.
[0169] In some embodiments, the execution module 230 is configured to stop defrosting from the (j+k+2)th to the (j+k+2+p)th defrosting if the duration of the (j+k+1)th defrosting is less than the target duration dn1 in the paused defrosting mode, where p is a positive integer;
[0170] If the duration of the (j+k+1)th defrost is determined to be no less than the target duration dn1, exit the pause defrost mode.
[0171] In some embodiments, the execution module 230 is configured to stop defrosting from the j+k+p+4th to the j+k+p+4th+qth if the duration of the j+k+2+p+1th defrosting is less than the target duration dn1 in the paused defrosting mode, where q is a positive integer;
[0172] After completing the defrosting process from the j+k+p+4th to the j+k+p+4th+qthth, exit the paused defrosting mode.
[0173] In some embodiments, the execution module 230 is further configured to execute a supplementary defrosting mode when the duration of each of the m consecutive defrostings gradually increases within a preset time period, and the duration of each of the 1st to 1+m-1th defrostings is greater than the target duration dn1; where m is a positive integer.
[0174] The defrosting control device for the storage device in this application embodiment can be an electronic device or a component within an electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal or other devices besides a terminal. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, network attached storage (NAS), personal computer (PC), television (TV), ATM, or self-service machine, etc. This application embodiment does not specifically limit the specific type of device.
[0175] The defrosting control device for the storage device in this embodiment can be a device with an operating system. This operating system can be Microsoft Windows, Android, iOS, or other possible operating systems; this embodiment does not specifically limit the specific operating system used.
[0176] The defrosting control device for storage equipment provided in this application embodiment can achieve... Figure 1 The various processes implemented in the method implementation examples will not be described again here to avoid repetition.
[0177] This application also discloses a storage device.
[0178] In some embodiments, the storage device includes a compressor 10 and a defrosting control device as described in any of the above-described storage devices, the defrosting control device being electrically connected to the compressor 10.
[0179] It should be noted that storage equipment can be understood in a broad sense as refrigeration and storage equipment, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. Storage equipment has diverse structural forms and a wide range of applications. As a specific example, this application embodiment uses a vending freezer as an illustration, which is used to sell frozen goods, such as ice cream and ice cubes.
[0180] The storage device provided in this application embodiment improves defrosting efficiency and reduces defrosting energy consumption by setting the defrosting control device of the storage device, thereby improving the overall performance and adaptability of the storage device.
[0181] In some embodiments, such as Figure 2 As shown, the defrosting system of the storage equipment includes a refrigeration circuit, which includes a compressor 10, a condenser 20, a dryer filter 30, a capillary tube 40, and an evaporator 50 connected in sequence.
[0182] Understandably, the refrigerant is compressed into a high-temperature, high-pressure gaseous state by the compressor 10 and then enters the condenser 20 to be cooled into a liquid state. The liquid refrigerant passes through the dryer filter 30 to remove impurities and moisture and then enters the capillary tube 40 for throttling and pressure reduction. The low-temperature, low-pressure refrigerant enters the evaporator 50, absorbs heat, vaporizes into a gaseous state, and flows into the compressor 10, thereby achieving the cooling of the room.
[0183] In some embodiments, such as Figure 2 As shown, multiple condensers 20 are provided to improve refrigeration efficiency. For example, four condensers 20 are provided.
[0184] In some embodiments, such as Figure 2As shown, the defrosting system also includes a bypass branch and a heating element. A defrost valve 60 is provided on the bypass branch, located between the compressor 10 and the evaporator 50. The heating element is used to heat at least one of the compartments formed by the evaporator 50 and the storage device. The defrost valve 60 includes, but is not limited to, a solenoid valve. The heating element includes, but is not limited to, a heating wire.
[0185] Understandably, on the one hand, the bypass branch is connected to the refrigeration circuit. That is, when the defrost valve 60 is open, the high-temperature, high-pressure gaseous refrigerant flowing from the compressor 10 can directly flow into the evaporator 50 through the defrost valve 60 to heat the surface of the evaporator 50 and melt the defrost layer. This utilizes the existing high-temperature refrigerant in the refrigeration circuit to heat the evaporator 50, further reducing energy consumption. On the other hand, by using a heating element to heat the evaporator 50 or the compartment, the space within the compartment can also be heated, accelerating the melting of the frost layer and improving the defrosting effect. In this embodiment, the heating element is installed inside the compartment. Of course, in other embodiments, the heating element can also be placed close to the evaporator 50; this embodiment does not impose specific limitations on this.
[0186] In some embodiments, such as Figure 2 As shown, a silencer 70 is provided between the compressor 10 and the defrost valve 60 to reduce the noise and pressure pulsation generated during the operation of the compressor 10, while providing additional protection during the defrosting process.
[0187] In some embodiments, such as Figure 6 As shown, this application embodiment also provides an electronic device 800, including a processor 801, a memory 802, and a computer program stored in the memory 802 and executable on the processor 801. When the program is executed by the processor 801, it implements the various processes of the above-described storage device defrosting control method embodiment and can achieve the same technical effect.

To avoid repetition, it will not be described again here.
