Technical Field
[0001] This application relates to the field of refrigerator technology, specifically to a refrigeration drainage component, a refrigerator, a control method, and a storage medium. Background Technology
[0002] French-style refrigerators, due to their unique structural design, typically have the refrigerator compartment, variable temperature compartment, and freezer compartment closely connected. During drainage, the drain pipe in the refrigerator compartment is susceptible to the low temperature of the freezer compartment, causing the water inside to freeze and become blocked. This not only affects the normal operation of the refrigerator but can also lead to water accumulation in the refrigerator compartment, affecting the preservation quality of food.
[0003] In existing technologies, the problem of ice blockage is usually solved by heating the drain pipe. However, the design of the heating device often fails to fully consider the risk of ice formation in different areas of the drain pipe, resulting in low heating efficiency or excessive energy consumption.
[0004] Therefore, the technology still needs to be improved and enhanced. Summary of the Invention
[0005] This application provides a refrigeration drainage component, a refrigerator, a control method, and a storage medium, which can ensure that the refrigerator achieves energy-saving effects while efficiently preventing ice blockage in the refrigeration drainage pipe.
[0006] A refrigerator drainage assembly is used in a refrigerator, the refrigerator including a refrigerator compartment, a variable temperature compartment and a freezer compartment, the refrigerator drainage assembly comprising: A drain pipe, connected to the refrigerator compartment, is used to drain the defrost water generated in the refrigerator compartment. The drain pipe includes a first pipe section and a second pipe section connected in sequence. The first pipe section is used to be installed in the variable temperature compartment, and the second pipe section is used to be installed in the freezer compartment. A first heating wire is disposed in the drain pipe and extends from one end to the other end along the length of the first pipe segment. A second heating wire is disposed in the drain pipe. The second heating wire extends from one end to the other end along the length of the second pipe segment and extends to the tail end portion of the first pipe segment that is adapted to connect with the second pipe segment.
[0007] In some embodiments, the first heating wire extends to the head portion of the second tube segment adapted to connect with the first tube segment.
[0008] In some embodiments, the first heating wire and / or the second heating wire are wound around the drain pipe.
[0009] In some embodiments, both the first heating wire and the second heating wire are wound around the drain pipe, and the winding spacing of the second heating wire is smaller than that of the first heating wire.
[0010] A refrigerator includes a refrigerator compartment, a variable temperature compartment, a freezer compartment, and the aforementioned refrigerator drainage components.
[0011] A control method, applied to the aforementioned refrigerator, includes: Get the current ambient temperature; If the ambient temperature is lower than the preset temperature threshold, the second heating wire is turned on, and the set temperature of the variable temperature chamber is obtained. The operating state of the first heating wire is controlled according to the set temperature.
[0012] In some embodiments, controlling the operating state of the first heating wire according to the set temperature includes: If the set temperature is greater than the first preset temperature, then the first heating wire is turned off. If the set temperature is less than or equal to the first preset temperature, then the first heating wire is turned on.
[0013] In some embodiments, controlling the first heating wire to turn on includes: If the set temperature is greater than the second preset temperature, the heating wire is controlled to turn on at the first preset power, and the second preset temperature is less than the first preset temperature; If the set temperature is less than or equal to the second preset temperature and greater than the third preset temperature, then the heating wire is controlled to turn on at the second preset power, wherein the third preset temperature is less than the second preset temperature and the second preset power is greater than the first preset power; If the set temperature is less than or equal to the third preset temperature and greater than the fourth preset temperature, then the heating wire is controlled to turn on at the third preset power, where the fourth preset temperature is less than the third preset temperature and the third preset power is greater than the second preset power.
[0014] In some embodiments, after controlling the second heating wire to turn on, the method further includes: Check if the second heating wire is malfunctioning; If the second heating wire malfunctions, the first heating wire is turned on, and the operating power of the first heating wire is adjusted according to the set temperature of the variable temperature chamber.
[0015] A storage medium having a computer program stored thereon, wherein the computer program executes the above-described control method when it is run.
[0016] The refrigeration drainage assembly, refrigerator, control method, and storage medium provided in this application achieve precise zoned heating and antifreeze by installing a first heating wire and a second heating wire on different pipe sections corresponding to the variable temperature compartment and the freezer compartment, respectively, and ensuring that the heating wires extend along the entire length of their respective pipe sections. This ensures that defrosting water from the refrigerator can be smoothly discharged throughout the entire drainage path, greatly improving drainage reliability. In particular, the extension of the second heating wire to the end of the first pipe section effectively eliminates antifreeze blind spots at the connection between the two pipe sections and in the temperature transition zone. Furthermore, when the possibility of freezing in the first pipe section is low, the first heating wire can be turned off, and only a small amount of heat from the second heating wire is transferred to the first pipe section to prevent freezing. This reduces energy waste and avoids overall overheating. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0026] This application provides a refrigeration drainage component for a refrigerator. For an example, please refer to [link to example]. Figure 1 , Figure 1 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. The refrigerator 10 includes a refrigerator compartment 100, a variable temperature compartment 200, a freezer compartment 300, and a refrigerator drain assembly 400. The refrigerator drain assembly 400 includes a drain pipe 410, a first heating wire 420, and a second heating wire 430.
[0027] The refrigerator compartment 100 is equipped with a refrigerator evaporator, which produces defrost water during the defrosting process. The refrigerator compartment 100, the variable temperature compartment 200, and the freezer compartment 300 are arranged adjacent to each other from top to bottom. The variable temperature compartment 200 and the freezer compartment 300 include an inner liner and a cabinet body. The inner liner encloses the internal storage space, forming a compartment, while the cabinet body surrounds the inner liner and forms a partition between the inner liner and the cabinet body. The partition body may be filled with, for example, foam material. A drain pipe 410 is connected at one end to the bottom of the refrigerator compartment 100 and extends downwards from the refrigerator compartment 100, passing sequentially through the cabinet body of the variable temperature compartment 200 and the cabinet body of the freezer compartment 300, for example, extending to the drip tray of the refrigerator 100; the drain pipe 410 is used to drain the defrost water produced in the refrigerator compartment 100.
[0028] The drain pipe 410 includes a first pipe segment and a second pipe segment connected in sequence. The first pipe segment is located in the housing portion of the variable temperature compartment 200, and the second pipe segment is located in the housing portion of the freezer compartment 300. A first heating wire 420 is disposed in the drain pipe 410 and extends from one end of the first pipe segment to the other end along its length. A second heating wire 430 is disposed in the drain pipe 410 and extends from one end of the second pipe segment to the other end, extending to the tail end portion of the first pipe segment suitable for connection with the second pipe segment. The first heating wire 420 and / or the second heating wire 430 are arranged in a wound manner in the drain pipe 410. Preferably, both the first heating wire 420 and the second heating wire 430 are arranged in a wound manner in the drain pipe 410, having an overlapping area but maintaining a distance between them. The winding spacing of the second heating wire is smaller than that of the first heating wire. This increases the extension length of the second heating wire and improves its heating efficiency. By transferring more heat to the first tube segment, it is beneficial to improve the heating efficiency of the first tube segment and reduce the start-up frequency of the first heating wire.
[0029] Understandably, in low-temperature environments, the water inside the drain pipe 410 is prone to freezing. In particular, because the freezer compartment 300 needs to maintain a low-temperature environment, the second section of the drain pipe 410 is more likely to freeze. For the variable temperature compartment 200, due to its wide temperature setting range, its impact on the freezing of the first section of the drain pipe 410 in low-temperature environments depends on the actual set temperature. That is, the higher the set temperature of the variable temperature compartment 200, the lower the likelihood of freezing in the first section; conversely, the lower the set temperature of the variable temperature compartment 200, the higher the likelihood of freezing in the first section.
[0030] The first heating wire 420 and the second heating wire 430 can be turned on individually or simultaneously. In practical applications, at least the second heating wire 430 can be turned on even in low-temperature environments. Since the second heating wire 430 extends along the entire length of the second pipe section, it can effectively solve the icing problem of the second pipe section. Furthermore, the second heating wire 430 extends to the tail end of the first pipe section, and its heat can be partially transferred to the first pipe section. Even if the first heating wire 420 is not turned on, the possibility of icing can still be reduced through the second heating wire 430. The first heating wire 420 can be turned on or off based on the actual set temperature of the variable temperature chamber 200. If the actual set temperature of the variable temperature chamber 200 is high, the possibility of icing in the first pipe section is low, so the first heating wire 420 can be turned off, and icing can be avoided only by the small amount of heat from the second heating wire 430, thus avoiding energy waste. If the actual set temperature of the variable temperature chamber 200 is low, the first heating wire 420 can be turned on, achieving efficient anti-icing by heating the entire first pipe section.
[0031] Optionally, the first heating wire 420 also extends to the beginning portion of the second pipe section suitable for connection with the first pipe section. It is understood that for the variable temperature chamber 200 with cryogenic and speed functions, its set temperature may be extremely low, such as -30°C, which may cause the first pipe section to freeze even at normal ambient temperatures. In practical applications, the first heating wire 420 can be turned on independently when the ambient temperature is normal but the set temperature of the variable temperature chamber 200 is below -20°C, to achieve efficient heating of the first pipe section. Simultaneously, the portion of the first heating wire 420 extending to the second pipe section can heat the second pipe section, preventing it from freezing.
[0032] The refrigeration drainage assembly 400 provided in this application embodiment achieves precise zoned heating and antifreeze by respectively installing a first heating wire 420 and a second heating wire 430 on different pipe sections of the drain pipe 410 corresponding to the variable temperature compartment 200 and the freezer compartment 300, and ensuring that the heating wires extend along the entire length of their respective pipe sections. This ensures that defrosting water from the refrigeration unit can be smoothly discharged throughout the entire drainage path, greatly improving drainage reliability. In particular, the second heating wire 430 extending to the end of the first pipe section effectively eliminates the antifreeze blind spot at the connection between the two pipe sections and in the temperature transition zone. Furthermore, when the possibility of freezing in the first pipe section is low, the first heating wire 420 can be turned off, and only a small amount of heat from the second heating wire 430 is transferred to the first pipe section to prevent freezing. This reduces energy waste and avoids overall overheating.
[0033] This application also provides a refrigerator, such as... Figures 1-2 As shown, Figure 2 This is another structural schematic diagram of a refrigerator provided in an embodiment of this application. The refrigerator 10 includes a refrigerator compartment 100, a variable temperature compartment 200, a freezer compartment 300, and a refrigerator drainage assembly 400 provided in any of the above embodiments.
[0034] The refrigerator provided in this application embodiment has a refrigeration drainage assembly 400 that, by respectively installing a first heating wire 420 and a second heating wire 430 on different pipe sections of the drain pipe 410 corresponding to the variable temperature compartment 200 and the freezer compartment 300, and ensuring that the heating wires extend along the entire length of their respective pipe sections, achieves precise zoned heating and antifreeze, ensuring that defrosting water can be smoothly discharged throughout the entire drainage path, greatly improving drainage reliability. In particular, the second heating wire 430 extending to the end of the first pipe section effectively eliminates the antifreeze blind spot at the connection between the two pipe sections and in the temperature transition zone; on the other hand, when the possibility of freezing in the first pipe section is small, the first heating wire 420 can be turned off, and only a small amount of heat from the second heating wire 430 is transferred to the first pipe section to prevent freezing, thus reducing energy waste.
[0035] This application also provides a control method applied to the above-mentioned refrigerator; for example, please refer to [link to example]. Figure 3 , Figure 3 A flowchart illustrating a control method provided in an embodiment of this application. The control method includes the following steps S101-S103: Step S101: Obtain the current ambient temperature; Ambient temperature is acquired through environmental sensors, such as digital temperature and humidity sensors or discrete temperature sensors. The environmental sensors collect data periodically at a preset sampling frequency (e.g., once per minute), or are triggered in real time by the control module.
[0036] Step S102: If the ambient temperature is lower than the preset temperature threshold, control the second heating wire to turn on and obtain the set temperature of the variable temperature chamber. It should be noted that when the ambient temperature is below the preset temperature threshold, the drain pipe of the refrigeration drainage assembly is prone to internal icing. In this case, activating the second heating element heats the drain pipe, preventing ice blockage. The preset temperature threshold can be 10°C. Optionally, if the ambient temperature is greater than or equal to the preset temperature threshold, both the first and second heating elements are kept off. The first heating element may be activated at full power or with a duty cycle of 80%.
[0037] The temperature setting for the variable temperature compartment can be manually set by the user, or it can be intelligently selected by the refrigerator based on the actual food storage conditions inside. The temperature range of the variable temperature compartment can be -20℃ to 8℃. For some variable temperature compartments with deep cooling and quick-freezing functions, the temperature range can even be -40℃ to 8℃.
[0038] Step S103: Control the operating status of the first heating wire according to the set temperature.
[0039] The operating status of the first heating wire may include its on / off state, and may also include its operating power state.
[0040] In practical applications, when a low ambient temperature is detected, the second heating wire is controlled to work continuously to heat the second pipe section and transfer some of the heat to the first pipe section. When the temperature setting of the variable temperature chamber is high, it can meet the anti-icing requirements of the drain pipe alone without activating the first heating wire, thus achieving energy-saving effects. When the temperature setting of the variable temperature chamber is low, the first heating wire can be activated to efficiently heat the first pipe section at the same time, ensuring that no ice blockage occurs along the entire drainage path of the drain pipe.
[0041] The refrigerator control method provided in this application embodiment controls the second heating wire to turn on when a low ambient temperature is detected, and controls the operation state of the first heating wire according to the set temperature of the variable temperature compartment. This enables zoned heating and on-demand heating of multiple sections of the drain pipe, achieving energy-saving effects while ensuring efficient anti-ice blockage of the refrigerated drain pipe.
[0042] Optionally, controlling the operating state of the first heating wire according to the set temperature includes: If the set temperature is higher than the first preset temperature, the first heating element will be turned off. If the set temperature is less than or equal to the first preset temperature, then the first heating wire is turned on.
[0043] The first preset temperature can be 0℃. To further improve the precision of the control of the first heating wire and make the heating of the first heating wire accurately match the actual demand, a target operating power corresponding to the preset temperature range into which the set temperature falls can be determined from multiple preset operating power values based on a preset mapping table, and the first heating wire can be controlled to turn on at the target operating power; the mapping table includes a one-to-one correspondence between multiple preset operating power values and multiple preset temperature ranges.
[0044] For example, controlling the first heating wire to turn on includes: If the set temperature is higher than the second preset temperature, the heating wire is controlled to turn on at the first preset power, and the second preset temperature is lower than the first preset temperature. If the set temperature is less than or equal to the second preset temperature and greater than the third preset temperature, the heating wire is controlled to turn on at the second preset power. The third preset temperature is less than the second preset temperature and the second preset power is greater than the first preset power. If the set temperature is less than or equal to the third preset temperature and greater than the fourth preset temperature, the heating wire is controlled to turn on at the third preset power. The fourth preset temperature is less than the third preset temperature, and the third preset power is greater than the second preset power.
[0045] Understandably, when the set temperature of the variable temperature chamber is higher than the second preset temperature but lower than or equal to the first preset temperature, the probability of ice formation inside the first pipe section is low. In this case, controlling the first heating wire to operate at low power, along with the supplementary heating from the second heating wire, can meet the current low heating requirement of the first pipe section. When the set temperature of the variable temperature chamber is lower than or equal to the second preset temperature but higher than the third preset temperature, the probability of ice formation inside the first pipe section is moderate. In this case, controlling the first heating wire to operate at medium power, along with the supplementary heating from the second heating wire, can meet the current normal heating requirement of the first pipe section. When the set temperature of the variable temperature chamber is lower than or equal to the third preset temperature but higher than the fourth preset temperature, the probability of ice formation inside the first pipe section is high. In this case, the first heating wire to operate at high power can match the current high heating requirement of the first pipe section.
[0046] In some embodiments, the second preset temperature is -5°C; the duty cycle of the heating wire when operating at the first preset power is a fixed 30%; the third preset temperature is -12°C; the duty cycle of the heating wire when operating at the second preset power is a fixed 60%; the third preset temperature is -20°C; and the duty cycle of the heating wire when operating at the third preset power is a fixed maximum of 100%.
[0047] In other embodiments, the first preset power, the second preset power, and the third preset power can also be target values determined based on the actual set power of the variable temperature chamber. This further achieves a precise match between the icing risk level and the heating amount. For example, when the set temperature is less than or equal to the second preset temperature and greater than the third preset temperature, i.e., when icing inside the first pipe section is of medium risk, a target duty cycle can be determined based on the set temperature, and the first heating wire can be controlled to turn on according to the target duty cycle, so that the first heating wire turns on at the target second preset power. The set temperature and the target duty cycle are inversely proportional. For example, the target duty cycle can be determined based on the following formula:
[0048] in, Indicates the target duty cycle; Indicates the set temperature; Indicates the second preset temperature; This indicates the third preset temperature, for example, -12℃; Indicates the preset maximum duty cycle; This indicates the preset minimum duty cycle, for example, 50%. Understandably, the target duty cycle D is between 50% and 80%.
[0049] The first and second heating wires may malfunction after prolonged use. If the first heating wire malfunctions, the second heating wire will continue to operate, ensuring that the second heating pipe section on the freezer side remains ice-free. Although the anti-ice-blocking effect of the first heating pipe section on the variable temperature compartment side decreases, the risk of ice formation can still be reduced by reminding the user to adjust the set temperature or by the refrigerator intelligently adjusting the upper limit of the set temperature, since the variable temperature compartment's set temperature is controllable. If the second heating wire malfunctions, such as with an open circuit or abnormal power, the reference power of the first heating wire can be automatically increased by one level after the abnormality is detected, allowing the first heating wire to take over the main anti-ice-blocking task, achieving degraded operation in the event of a single wire failure.
[0050] For example, after controlling the second heating wire to turn on, the control method further includes: Check if the second heating wire is malfunctioning; If the second heating wire malfunctions, the first heating wire is turned on, and its operating power is adjusted according to the set temperature of the variable temperature chamber.
[0051] To determine if the second heating wire is malfunctioning, one can check the current supplied when it is turned on, or monitor the temperature near the second heating wire (e.g., whether the temperature of the first pipe section rises), or use other detection methods. If the second heating wire fails, immediately turn on the first heating wire. This improves the reliability of preventing ice blockage in the drain pipe.
[0052] Furthermore, adjusting the operating power of the first heating wire according to the set temperature of the variable temperature chamber includes: If the set temperature is higher than the first preset temperature, the heating wire is controlled to turn on at the first preset power. If the set temperature is less than or equal to the first preset temperature and greater than the second preset temperature, the heating wire is controlled to turn on at the second preset power. If the set temperature is less than or equal to the second preset temperature and greater than the fourth preset temperature, the heating wire will be turned on at the preset maximum power.
[0053] For example, please refer to Figure 4 , Figure 4 Another flowchart of the control method provided in this application embodiment. The refrigerator control method includes the following steps S201-S216: Step S201: Obtain the current ambient temperature ; Step S202: Determine the current ambient temperature Is it below the preset temperature threshold? If the ambient temperature If the temperature is below the preset threshold, proceed to step S203; otherwise, return to step S201.

Step S206: Keep the first heating wire off; Step S207: Determine the set temperature Is it greater than the first preset temperature? ; If set temperature Greater than the first preset temperature If yes, proceed to step S208; otherwise, proceed to step S209. Step S208: Control the first heating wire to turn on at the first preset power; Step S209: Determine the set temperature Is it greater than the first preset temperature? ; If set temperature Greater than the first preset temperature If yes, proceed to step S210 below; otherwise, proceed to step S211 below. Step S210: Control the first heating wire to turn on at the second preset power; Step S211: Control the first heating wire to turn on at the third preset power; Step S212: Determine the set temperature Is it greater than the first preset temperature? ; If set temperature Greater than the first preset temperature If yes, proceed to step S213 below; otherwise, proceed to step S214 below. Step S213: Control the first heating wire to turn on at the first preset power; Step S214: Determine the set temperature Is it greater than the first preset temperature? ; If set temperature Greater than the first preset temperature If yes, proceed to step S215 below; otherwise, proceed to step S216 below. Step S215: Control the first heating wire to turn on at the second preset power; Step S216: Control the first heating wire to turn on at the third preset power; The refrigerator 10 control method provided in this application embodiment controls the second heating wire to turn on when the ambient low temperature is detected, and controls the operation state of the first heating wire according to the set temperature of the variable temperature compartment.
