Description

Technical Field

[0001] This invention relates to the field of defrosting technology, and in particular to a refrigeration device and its defrosting method and apparatus. Background Technology

[0002] Thick frost in refrigeration equipment can affect the heat exchange efficiency of the refrigerator, thereby affecting the refrigeration capacity and preservation ability of the refrigeration equipment, and also making the refrigeration equipment consume more electricity.

[0003] Taking refrigerators as an example, in related technologies, the defrosting control methods for refrigerators mainly include the following two approaches:

[0004] The defrosting interval is fixed based on the environmental parameters of the refrigerator's environment. Each time the door is opened, the defrosting interval is reduced, and the time is reset after defrosting is complete. This control method is difficult to match various real-world situations.

[0005] Alternatively, defrosting can be started or stopped by detecting the thickness of the frost layer, but this requires adding an extra sensor, which is more expensive. Summary of the Invention

[0063] like Figures 1 to 3 As shown, a first aspect of the present invention provides a defrosting method for a refrigeration device, comprising:

[0064] Step 100: Obtain the reference cooling rate of the compartment;

[0065] Step 200: Obtain the actual cooling rate of the compartment;

[0066] Step 300: Determine the comparison result between the actual cooling rate and the reference cooling rate, and then perform defrosting.

[0067] According to the first aspect of the present invention, the defrosting method for a refrigeration device obtains the reference cooling rate and the actual cooling rate of the compartment, compares the reference cooling rate with the actual cooling rate, and determines whether to defrost based on the specific comparison result. This defrosting method does not require the addition of new sensors, and the determination of whether to defrost can be achieved by only improving the control logic. This not only reduces the control cost of determining whether to defrost, but also has the advantages of being simple, easy to implement, and highly reliable.

[0068] The following example uses a refrigerator as the refrigeration equipment. Please continue reading. Figures 1 to 3 In the defrosting method provided in this embodiment of the invention, step 100 is used to obtain the reference cooling rate of the compartment; step 200 is used to obtain the actual cooling rate of the compartment; and step 300 is used to determine whether defrosting is required based on the comparison result between the reference cooling rate of the compartment obtained in step 100 and the actual cooling rate of the compartment obtained in step 200.

[0069] In this embodiment of the invention, the defrosting method of the refrigeration equipment can be implemented in at least the following two ways:

[0070] Implementation method 1:

[0071] See also Figure 1 and Figure 2 In this implementation, the reference cooling rate of the room can be obtained by step 110: the temperature sensor of the room obtains the first cooling time of the room from the initial temperature to the target temperature.

[0072] For example, the initial temperature of the compartment can be set to t1, and the target temperature of the compartment can be set to t2. After the setting is completed, the compressor 100 is turned on to cool the compartment. When the compressor 100 is turned on, the first cooling time of the temperature in the compartment from the initial temperature t1 to the target temperature t2 is recorded.

[0073] In other words, in this implementation, the reference cooling rate of the room can be obtained by the first cooling time taken for the temperature in the room to drop from the initial temperature to the target temperature.

[0074] After the refrigerator has been running for a period of time, step 210 can be used to obtain the second cooling time from the initial temperature to the target temperature of the compartment.

[0075] For example, after the refrigerator has been running for a period of time, the initial temperature of the compartment can be set to t1 again, and the target temperature of the compartment can be set to t2. After the setting is completed, the compressor 100 is turned on to cool the compartment. When the compressor 100 is turned on, the second cooling time from the initial temperature t1 to the target temperature t2 is recorded.

[0076] In other words, after the refrigerator has been running for a period of time, the actual cooling rate of the compartment can be obtained by measuring the second cooling time required for the temperature inside the compartment to drop from the initial temperature to the target temperature.

[0077] After obtaining the reference cooling rate and the actual cooling rate of the compartment, step 310 is used to determine the comparison result between the actual cooling rate and the reference cooling rate, and to determine whether defrosting should be performed.

[0078] Understandably, in this step, the second cooling time is compared with the first cooling time. If the difference between the second cooling time and the first cooling time is greater than the preset cooling time difference, then it is determined that a defrosting operation should be performed; if the difference between the second cooling time and the first cooling time is less than the preset cooling time difference or the second cooling time is equal to the first cooling time, then it is determined that no defrosting operation is required.

[0079] It should be noted that the preset cooling time difference mentioned here can be obtained by multiplying the first cooling time by a certain coefficient. For example, if the first cooling time is 1 hour, then the preset cooling time difference can be 10 minutes.

[0080] For example, if the first cooling time is 1 hour and the second cooling time is 55 minutes, and the preset cooling time difference is 10 minutes, and the difference between the first cooling time and the second cooling time is 5 minutes, then if 5 minutes is less than the preset cooling time difference of 10 minutes, it means that defrosting is not required at this time.

[0081] If the first cooling time is 1 hour, the second cooling time is 40 minutes, the preset cooling time difference is 10 minutes, and the difference between the first and second cooling times is 20 minutes, then 20 minutes is greater than the preset cooling time difference of 10 minutes, indicating that defrosting is currently being performed to improve the refrigerator's cooling capacity.

[0082] Implementation Method Two:

[0083] See also Figure 1 and Figure 3 In this implementation, the reference cooling rate of the room can be obtained by step 120: the first temperature difference between the initial temperature and the first detection temperature of the room within a preset time.

[0084] For example, the initial temperature of the compartment can be set to t1, and the preset time can be set to T2. After the setting is completed, the compressor 100 is turned on to cool the compartment. After the preset time T2, the temperature in the compartment is detected again to obtain the specific temperature value of the first detected temperature in the compartment.

[0085] That is, in this implementation, the reference cooling rate of the room can be obtained by step 220: within a preset time period, the temperature difference between the initial temperature and the first detection temperature in the room.

[0086] After the refrigerator has been running for a period of time, the actual cooling rate of the compartment can be obtained by measuring the second temperature difference between the initial temperature and the second detection temperature within a preset time period.

[0087] For example, after the refrigerator has been running for a period of time, the initial temperature of the compartment can be set to t1 again, and the preset time can be set to T2. After the setting is completed, the compressor 100 is turned on to cool the compartment. After the preset time T2, the temperature inside the compartment is detected again to obtain the specific temperature value of the second detected temperature inside the compartment.

[0088] That is, in this implementation, the actual cooling rate of the room can be obtained by step 320: within a preset time period, the temperature difference between the initial temperature and the second detection temperature in the room is used to obtain the actual cooling rate of the room.

[0089] After obtaining the reference cooling rate and the actual cooling rate of the compartment, the comparison between the actual cooling rate and the reference cooling rate is used to determine whether defrosting should be performed.

[0090] Understandably, in this step, the second temperature difference is compared with the first temperature difference. If the difference between the second temperature difference and the first temperature difference is greater than the preset temperature difference, then it is determined that a defrosting operation should be performed; if the difference between the second temperature difference and the first temperature difference is less than the preset temperature difference or the second temperature difference is equal to the first temperature difference, then it is determined that no defrosting operation is required.

[0091] For example, if the first temperature difference is 10 degrees Celsius, the second temperature difference is 12 degrees Celsius, the preset temperature difference is 5 degrees Celsius, and the difference between the first and second temperature differences is 2 degrees Celsius, then 2 degrees Celsius is less than the preset temperature difference of 5 degrees Celsius, indicating that defrosting is not required at this time.

[0092] If the first temperature difference is 10 degrees Celsius, the second temperature difference is 3 degrees Celsius, the preset temperature difference is 5 degrees Celsius, and the difference between the first and second temperature differences is 7 degrees Celsius, which is greater than the preset temperature difference of 5 degrees Celsius, then it means that defrosting is currently being performed to improve the refrigerator's cooling capacity.

[0093] See Figure 1 According to one embodiment of the present invention, the step of obtaining the reference cooling rate of the compartment further includes:

[0094] The chamber is brought back to its initial temperature, and the predetermined speed of compressor 100 is determined based on the ambient temperature th of the chamber.

[0095] For example, in this step, after the refrigerator has been powered on and running stably for a period of time, the initial defrosting operation is performed. After defrosting, once the second start-stop cycle of compressor 100 is completed, the refrigerator's initial cooling capacity is tested. Taking the freezer compartment as an example, to eliminate interference from the refrigerator compartment, the refrigerator damper is closed. At this time, compressor 100 stops, allowing the freezer compartment to return to its initial temperature. Then, based on the ambient temperature th at the refrigerator's location, compressor 100 is started at a preset speed to cool the freezer compartment, thereby testing the refrigerator's cooling capacity.

[0096] According to one embodiment of the present invention, the step of adjusting the speed of compressor 100 by a predetermined speed based on the ambient temperature th of the compartment further includes:

[0097] If the actual fluctuation value of the ambient temperature th in the compartment is found to be greater than the preset fluctuation value, adjust the preset speed of the compressor 100.

[0098] In other words, in this step, if the ambient temperature (th) at the refrigerator's location changes, the compressor 100's preset speed needs to be readjusted based on the new ambient temperature (th) to redetermine the refrigerator's cooling capacity. This allows for a more accurate acquisition of the compartment's reference cooling rate. Understandably, if the actual fluctuation of the ambient temperature (th) at the refrigerator's location is greater than the preset fluctuation value, the compressor 100's preset speed is readjusted according to the new ambient temperature (th). That is, if the new ambient temperature (th) increases, the compressor 100's preset speed is increased; if the new ambient temperature (th) decreases, the compressor 100's preset speed is decreased. See the table below for an example:

[0099]

[0100] Table 1

[0101] like Figure 4As shown, a single-system refrigerator mainly includes components such as a compressor 100, a condenser 102, a capillary tube 104, and an evaporator 106. The defrosting method provided in this embodiment of the invention will be described below using a single-system refrigerator as an example:

[0102] First, after the refrigerator has been running stably for 24 hours after being powered on, perform the first defrost. After defrosting, after the compressor completes its second start-stop cycle, perform the first cooling capacity test. At this time, the refrigerator's cold air door is closed to eliminate the influence of the cold air compartment on the cooling capacity test.

[0103] Then, the compressor 100 is stopped, allowing the initial temperature of the freezer compartment to return to -16 degrees Celsius. Subsequently, the predetermined speed of the compressor 100 is adjusted to cool the freezer compartment according to the ambient temperature corresponding to the table below, and this process is continued for 1 hour while the first detection temperature of the freezer compartment is measured.

[0104]

[0105] Table 2

[0106] Secondly, the cooling capacity is tested every 24 hours following the steps above. The first temperature of the freezer compartment detected in this step is compared with the first temperature of the freezer compartment detected in the previous step. If the difference between the two is greater than 0.5 degrees Celsius, the freezer compartment is defrosted.

[0107] Finally, if the actual fluctuation of the ambient temperature is greater than the preset fluctuation value, repeat the first step above, and determine whether defrosting is necessary according to the second and third steps above.

[0108] like Figure 5 As shown, a single-system refrigerator mainly includes components such as a compressor 100, a condenser 102, an electric valve 108, a capillary tube 104, a refrigerator evaporator, and a freezer evaporator. The defrosting method provided in this embodiment of the invention will be described below in conjunction with a dual-system refrigerator:

[0109] First, after the refrigerator has been running stably for 24 hours, the first defrosting is performed. After defrosting, once the second start-stop cycle of compressor 100 is completed, the first cooling capacity test is performed. At this time, compressor 100 is stopped, allowing the initial temperature of the freezer compartment to return to -16 degrees Celsius. Then, the predetermined speed of compressor 100 is adjusted according to the ambient temperature corresponding to the table below to cool the freezer compartment for 1 hour, and the first detection temperature of the freezer compartment is measured. Next, the temperature of the refrigerator compartment is measured. If the initial temperature of the refrigerator compartment is greater than or equal to 8 degrees Celsius, cooling of the refrigerator compartment begins directly; otherwise, compressor 100 is stopped, allowing the initial temperature of the refrigerator compartment to return to 8 degrees Celsius. Then, the predetermined speed of compressor 100 is adjusted according to the ambient temperature corresponding to the table below to cool the refrigerator compartment for 0.5 hours, and the first detection temperature of the refrigerator compartment is measured.

[0110]

[0111] Table 3

[0112] Secondly, the cooling capacity is tested every 24 hours following the steps above. The first temperature of the freezer compartment detected in this step is compared with the first temperature of the freezer compartment detected in the previous step. If the difference between the two is greater than 0.5 degrees Celsius, the freezer compartment is defrosted.

[0113] Next, the cooling capacity of the cold storage compartment is tested. The difference between the first detected temperature of the cold storage compartment in this step and the initial temperature of the cold storage compartment in the previous step is calculated. Then, the difference between the first detected temperature of the cold storage compartment in the previous step and the initial temperature of the cold storage compartment in the previous step is calculated again. The two differences are calculated again. If the difference is greater than 0.5 degrees Celsius, the cold storage compartment is defrosted.

[0114] Finally, if the actual fluctuation of the ambient temperature is greater than the preset fluctuation value, repeat the first step above, and determine whether defrosting is necessary according to the second and third steps above.

[0115] A second aspect of the present invention provides a defrosting device for a refrigeration equipment, comprising:

[0116] The acquisition module is used to acquire the actual cooling rate of the compartment;

[0117] The determination module is used to determine the comparison result between the actual cooling rate and the reference cooling rate, and to perform defrosting.

[0118] The defrosting device for refrigeration equipment provided according to a second aspect embodiment of the present invention acquires a reference cooling rate of the compartment by setting an acquisition module, and compares the reference cooling rate with the actual cooling rate by setting a determination module. Based on the comparison result, it determines whether defrosting should be performed. This defrosting device does not require additional sensors; the determination of whether to defrost can be achieved simply by improving the control logic. This not only reduces the control cost of determining whether to defrost, but also has the advantages of simplicity, ease of implementation, and high reliability. Applying it to refrigeration equipment such as refrigerators simplifies the defrosting control logic and improves the defrosting control accuracy.

[0119] A third aspect of the present invention provides a refrigeration device, comprising:

[0120] The processor 110 executes the defrosting method of the refrigeration device described above when executing the computer program;

[0121] Temperature sensors are used to obtain the actual cooling rate of the room;

[0122] The processor 110 defrosts based on a comparison between the actual cooling rate and the reference cooling rate.

[0123] According to the third aspect of the present invention, the refrigeration device is implemented by a processor, so that the refrigeration device does not need to add new sensors. Only the control logic needs to be improved to determine whether to defrost. This not only reduces the control cost of determining whether to defrost, but also effectively ensures the defrosting capability of the refrigeration device and improves the defrosting control accuracy of the refrigeration device.

[0124] Figure 6 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 6 As shown, the electronic device may include: a processor 110, a communication interface 112, a memory 114, and a communication bus 116, wherein the processor 110, the communication interface 112, and the memory 114 communicate with each other through the communication bus 116. The processor 110 can call logical instructions in the memory 114 to execute the following methods:

[0125] Obtain the actual cooling rate of the compartment;

[0126] Determine the comparison result between the actual cooling rate and the reference cooling rate, and then perform defrosting.

[0127] Furthermore, the logical instructions in the aforementioned memory 114 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to related technologies, or a part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods described in the various embodiments of the present invention. The aforementioned storage medium includes various media capable of storing program code, such as a USB flash drive, a portable hard drive, a read-only memory 114 (ROM), a random access memory 114 (RAM), a magnetic disk, or an optical disk.

[0128] This invention discloses a computer program product, which includes a computer program stored on a non-transitory computer-readable storage medium. The computer program includes program instructions, and when the program instructions are executed by a computer, the computer can perform the defrosting method for the refrigeration equipment provided in the above-described method embodiments, for example including:

[0129] Obtain the actual cooling rate of the compartment;

[0130] Determine the comparison result between the actual cooling rate and the reference cooling rate, and then perform defrosting.

[0131] On the other hand, embodiments of the present invention also provide a non-transitory computer-readable storage medium storing a computer program thereon, which, when executed by processor 110, implements a defrosting method for the refrigeration device provided in the above embodiments, including, for example:

[0132] Obtain the actual cooling rate of the compartment;

[0133] Determine the comparison result between the actual cooling rate and the reference cooling rate, and then perform defrosting.

[0134] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units.

Claims

1. A defrosting method for a refrigeration device, characterized in that, include: After the refrigerator is powered on and running stably, the first defrosting operation is performed. After defrosting, after the second start-stop cycle of the compressor is completed, the first cooling capacity of the refrigerator is tested to obtain the reference cooling rate of the freezer compartment. The steps for obtaining the reference cooling rate include: closing the refrigerator door to isolate the refrigerator compartment, at which time the compressor stops; restoring the freezer compartment to the initial temperature; determining the predetermined speed of the compressor based on the ambient temperature of the freezer compartment; and starting the compressor (100) at the predetermined speed to cool the freezer compartment based on the ambient temperature of the refrigerator's location; and within a preset time period, using the first temperature difference between the initial temperature and the first detection temperature of the freezer compartment as the reference cooling rate. The cooling capacity is tested every 24 hours following the steps described above. Within a preset time period, the actual cooling rate is the second temperature difference between the initial temperature and the second test temperature in the freezer compartment. If the difference between the second temperature difference and the first temperature difference is greater than the preset temperature difference, then a defrosting operation is determined. If it is determined that the actual fluctuation value of the ambient temperature of the freezer compartment is greater than the preset fluctuation value, the predetermined speed of the compressor (100) is adjusted to re-obtain the reference cooling rate of the freezer compartment.
