Abstract
Description
Technical Field
[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a control method, device, storage medium, and refrigerator for a refrigerator. Background Technology
[0002] Refrigerators with built-in ice makers are in high demand in the export high-end product market and are very popular with consumers.
[0003] Based on the ice removal method, ice makers are mainly divided into twist ice makers and scraping ice makers. Twist ice makers mainly consist of a frame, a rotating motor, and an ice tray. The frame is fixed inside the ice-making chamber, the rotating motor is fixedly located at one end of the frame, the front end of the ice tray is connected to the output shaft of the rotating motor, and the rear end of the ice tray is rotatably mounted on the other end of the frame. Both the rear end of the ice tray and the other end of the frame have mutually cooperating limiting structures.
[0004] The ice-making process of an ice maker involves the following steps: water injection, freezing, and ice removal. During ice making, a measured amount of water is injected into the ice tray through a water supply pipe connected to an external water source. The refrigerator's cooling system cools the water in the ice tray to its freezing point, causing it to freeze. Once the ice is solid, the ice removal process begins. During ice removal, a rotary motor drives the ice tray to rotate. When the rear end of the ice tray engages with the limiting structure on the frame, the rear end of the ice tray cannot continue rotating, while the rotary motor drives the front end to continue rotating. This causes the ice tray to twist and deform, allowing the ice to fall from the ice tray into the ice storage box below.
[0005] However, in the actual defrosting process, incomplete defrosting occasionally occurs. Existing refrigerator equipment cannot identify or handle incomplete defrosting, which can easily lead to more severe incomplete defrosting with each ice-making cycle. For example, ice cubes may stick together or harden, greatly affecting the user experience and even causing ice maker malfunctions.
[0006] Therefore, existing technologies urgently need improvement. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.
[0046] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0047] A preferred embodiment of the present invention provides a refrigerator control method applicable to refrigerators equipped with a twist-type ice maker.
[0048] Twist-type ice makers are typically located inside the ice-making compartment. An ice storage tray is usually located below the maker to collect the ice cubes that come off the maker. The ice-making compartment can be arranged differently depending on the type of refrigerator. For example, when a refrigerator has a refrigerator compartment and a freezer compartment, a separate compartment can be partitioned off within the refrigerator compartment as the ice-making compartment, and the twist-type ice maker can be placed inside this compartment; or the freezer compartment can be used directly as the ice-making compartment, meaning the twist-type ice maker can be placed directly inside the freezer compartment.
[0049] A twisting ice maker, applicable to a preferred embodiment of the present invention, includes at least a frame, a rotating mechanism, an ice tray, and a temperature sensor. The rotating mechanism is located at one end of the frame, the front end of the ice tray is connected to the output shaft of the rotating mechanism, and the rear end of the ice tray is rotatably located at the other end of the frame. The rear end of the ice tray and the other end of the frame are respectively provided with mutually cooperating limiting structures to restrict the rotation range of the rear end of the ice tray. For example, the rear end of the ice tray has a protrusion, and the frame has a limiting block at a predetermined position. When the ice tray rotates until the protrusion abuts against the limiting block, the rear end of the ice tray cannot continue to rotate, while the rotating mechanism drives the front end of the ice tray to continue rotating, thereby causing the ice tray to twist and deform, achieving ice flipping. Those skilled in the art should understand that the limiting structures provided on the rear end of the ice tray and the other end of the frame are not limited to the examples above. Any limiting structure that can achieve the function of "limiting the rotation range of the rear end of the ice tray when they cooperate" should be included within the scope of protection of this application. After one ice-turning cycle is completed, the rotating mechanism drives the ice grid to return to its original state (horizontal state).
[0050] The temperature sensor is located at the bottom of the frontmost ice tray, preferably at the bottom of the very frontmost ice tray. The applicant discovered that because the rotating mechanism is located at one end of the ice tray, and the ice tray has a certain length, the deformation at both ends of the ice tray differs during the twisting process. The ice tray experiences the smallest deformation during twisting and deformation at the front end near the rotating mechanism. Furthermore, based on market and laboratory verification, the applicant has determined that incomplete ice removal typically begins at the front of the ice tray. When incomplete ice removal occurs, the normal water volume for the next filling, plus the remaining ice in the ice tray, actually exceeds the tray's intended water volume. This causes the ice produced in the next batch to stick together. Sticky ice further hinders ice removal and increases the likelihood of incomplete removal. Therefore, when incomplete defrosting occurs repeatedly and accumulates, the ice in the ice tray becomes very large, preventing the injected water from entering the ice tray and causing it to overflow into the ice storage box below. This eventually leads to ice hardening inside the ice storage box, affecting the user experience and causing the ice maker to malfunction. As can be seen from the following preferred embodiment of the refrigerator control method of the present invention, this application places the temperature sensor at the bottom of the ice tray, where the ice tray is located at the front, which facilitates more accurate identification and handling of incomplete defrosting at an early stage.
[0051] The ice-making process of a twist-type ice maker includes water injection, freezing, and ice removal. It's important to note that during operation, the refrigerator's cooling system may simultaneously supply cooling to the ice trays at the start of water injection to achieve freezing. For clarity, this application does not use the start time of cooling as the beginning of the freezing process. Instead, the ice-making process is divided into three steps based on time periods: the water injection step, from the start of water injection to several minutes (e.g., 3-10 minutes) after it stops; the ice-flipping time, defined as the time from the start of the rotating mechanism to the time when the rotating mechanism returns the ice trays to their original state; and the ice removal step, defined as the time between the end of the water injection step and the start of the ice removal step. The water injection step corresponds to a preset amount of water, and the ice removal step corresponds to a preset number of ice flips.
[0052] See Figure 1 , Figure 1 This is a flowchart of a refrigerator control method according to a preferred embodiment of the present invention, including the following steps S1-S3. A control device is provided inside the refrigerator for executing the refrigerator control method.
[0053] Step S1 involves acquiring temperature change data during the water filling process of ice making when the ice tray is completely empty, and recording this data as baseline data. Here, "completely empty ice tray" means that there is no residual ice or water in any of the ice compartments.
[0054] Step S2 is: to acquire temperature change data during the water injection process of this round of ice making through the temperature sensor, and record it as the first temperature change data.
[0055] Step S3 is as follows: Compare the first temperature change data with the reference data, and determine whether the difference between the first temperature change data and the reference data meets a preset condition. When the difference between the first temperature change data and the reference data does not meet the preset condition, it is determined that there is no incomplete de-icing, and the ice-making step continues; when the difference between the first temperature change data and the reference data meets the preset condition, it is determined that there is incomplete de-icing, and the incomplete de-icing intervention operation S4 is performed.
[0056] Because ice making requires low temperatures, the ambient temperature inside the ice-making chamber is typically low, at least below -10°C. The water injected into the ice-making tray is flowing water introduced from outside the ice-making chamber, and its temperature is inevitably lower than the ambient temperature inside. Taking external water injection as an example, the water temperature is basically the same as the temperature inside the injection pipe, showing a significant difference from the ambient temperature inside the ice-making chamber. Therefore, when water is successfully injected into the ice-making tray, the temperature sensor reading will rise significantly. Generally, after the water injection is complete and the water has fully warmed up (approximately 3-10 minutes), the temperature sensor reading will stabilize. When water is injected into an ice-making tray with residual ice, the temperature rise characteristics during the injection process and the temperature value after warming up are significantly different from those when water is injected into an empty ice-making tray. Generally, the water injected into an ice-making tray with residual ice warms up less. Therefore, this application uses the temperature change data from the water injection process of this round of ice making as a basis for judgment to indirectly identify whether incomplete ice removal occurred in the previous round of ice making.
[0057] See Figure 1 The incomplete ice removal intervention operation S4 includes step S41: setting the number of ice-turning steps in the current ice-making cycle to be greater than the normal number of ice-turning steps or the number of ice-turning steps in the previous ice-making cycle. During an ice-making cycle, if incomplete ice removal is detected during the water injection step, increasing the number of ice-turning steps in the current cycle directly intervenes in the incomplete ice removal, which helps solve the problem. In practical design, the number of ice-turning steps can be set based on experimental data to ensure a high probability of achieving complete ice removal.
[0058] In some embodiments of this application, see Figure 1The incomplete ice removal intervention operation S4 further includes step S42: setting the water injection volume of the next round of ice making to be less than the water injection volume of the current round of ice making. In some embodiments of this application, the water injection volume of the next round of ice making is set to be less than or equal to 90% of the water injection volume of the current round of ice making, specifically 90%, 85%, 80%, 70%, or 60%, etc. The ratio of the water injection volume of the next round of ice making to the water injection volume of the current round of ice making can be set according to the structure of the ice grid. For example, when the ice grid has two rows and five columns, totaling ten ice grids, the two ice grids at the front are more likely to experience incomplete ice removal. Therefore, for this ice grid structure, setting the water injection volume of the next round of ice making to be 80% of the water injection volume of the current round of ice making is the most preferred. When incomplete ice removal is detected during the current round of ice making, even if the number of ice turnings in the current round is increased, it is difficult to ensure 100% complete ice removal. Furthermore, there is no measure to re-identify whether de-icing is complete after the de-icing step of the current ice-making process and before the water injection step of the next ice-making process begins. Therefore, when incomplete de-icing is detected during the current ice-making process, this application directly sets the water injection volume of the next ice-making process to be less than that of the current ice-making process. This setting effectively avoids injecting excessive water into the ice-making grid, which could cause the ice blocks produced in the next round to stick together, thus preventing even more unfavorable de-icing situations from occurring, even after increasing the number of ice-turning cycles in the current de-icing process.
[0059] In some embodiments of this application, see Figure 1 The incomplete ice removal intervention operation S4 further includes step S43: acquiring temperature change data for the water injection step of the next round of ice making, denoted as the second temperature change data; comparing the second temperature change data with the reference data; when the difference between the second temperature change data and the reference data meets a preset condition, it is determined that the incomplete ice removal situation still exists, and the incomplete ice removal intervention operation S4 is repeated. When the difference between the second temperature change data and the reference data does not meet the preset condition, it is determined that the incomplete ice removal problem has been resolved, the water injection volume for the next round of ice making is restored to the normal water injection volume, and the ice making step continues.
[0060] In some embodiments of this application, when the difference between the second temperature change data and the reference data does not meet the preset conditions, it is determined that the problem of incomplete ice removal has been resolved. The water injection volume for the next round of ice making is then restored to the normal injection volume, and the value of the normal ice-turning number is set to be greater than the original value, and the ice-making process continues. When incomplete ice removal occurs for the first time, it can be reasonably inferred that due to changes in certain factors, the preset normal ice-turning number is insufficient to achieve complete ice removal. Therefore, the normal ice-turning number can be modified by setting its value to be greater than the original value. For example, if the normal ice-turning number was originally set to 2 times, it can be modified to 3 times, thereby increasing the probability of complete ice removal.
[0061] In some embodiments of this application, when the cumulative number of times the incomplete ice removal intervention operation S4 is executed reaches a preset number of interventions, a prompt indicating that the ice grid is in an incomplete ice removal state is output, and the ice maker is controlled to stop making ice. Generally, it is set to control the ice maker to stop making ice after completing one round of ice making. The preset number of interventions can be flexibly designed according to the actual operation of the ice maker, and is generally set to 3-5 times. When the cumulative number of times the incomplete ice removal intervention operation S4 is executed reaches the preset number of interventions, it is determined that the incomplete ice removal situation still exists after multiple interventions. This may be due to a fault in the installation position or function of a component of the ice maker. At this time, a warning should be issued to remind the user to manually clean the ice and check whether there is a fault in the structure of the ice maker.
[0062] In some embodiments of this application, there are two ways to obtain the temperature change data (reference data) of the water filling step during ice making when the ice tray is completely empty. First, data can be pre-stored in the control device before shipment as the reference data. Second, when the user confirms that the ice tray is completely empty, the first round of ice making can be started, and the temperature change data of the water filling step during ice making when the ice tray is completely empty can be obtained through the temperature sensor and stored as the reference data.
[0063] In some embodiments of this application, the reference data, the first temperature change data, and the second temperature change data may be in two forms.
[0064] In the first scenario, the reference data, the first temperature change data, and the second temperature change data are all real-time temperature values after the water injection step is completed; that is, the reference data, the first temperature change data, and the second temperature change data are all single values. Specifically, according to the above description, the water injection step ends a few minutes (e.g., 3-10 minutes) after the water injection stops. At this time, the temperature of the injected water has stabilized, meaning the temperature sensor can measure a relatively stable temperature value at the end of the water injection step.
[0065] The second method involves fitting the reference data, the first temperature change data, and the second temperature change data into temperature change curves that are obtained by fitting real-time temperature values corresponding to several predetermined moments during the water injection process. For example, 10 predetermined moments are selected during the water injection process, and a real-time temperature value is measured at each predetermined moment by the temperature sensor. The 10 real-time temperature values are then fitted into a temperature change curve.
[0066] The preset conditions are adaptively set based on the form of the reference data, the first temperature change data, and the second temperature change data. That is, when the reference data, the first temperature change data, and the second temperature change data are all real-time temperature values, the differences between them can be directly compared; in other words, the preset condition can be a single numerical value. When the reference data, the first temperature change data, and the second temperature change data are all temperature change curves fitted from the real-time temperature values corresponding to several predetermined moments during the water injection process, the changing trends between them can be compared throughout the entire process or over a certain period; in other words, the preset condition should be data capable of characterizing differences in changing trends.
[0067] This invention also provides a refrigerator control device that can implement all the processes of the refrigerator control method described in any of the above embodiments. The functions and technical effects of each module in the device are the same as those of the refrigerator control method described in the above embodiments.

The one or more modules / units can be a series of computer program instruction segments capable of performing specific functions, and the instruction segments are used to describe the execution process of the computer program in the refrigerator.
