[0002] Many existing refrigerators have ice-making functions. Current ice-making fault reports only describe general faults and do not provide users with detailed explanations of possible causes and solutions. When users discover problems with their ice makers, they usually call the after-sales service center for repairs. However, users are often not familiar with the various performance aspects of the product. Because current technology can only indicate that the ice maker has malfunctioned, but cannot pinpoint the source of the malfunction in the ice maker's operation, communication and repair require a considerable amount of time.

[0028] Optionally, determining that the ice-out fault is a broken ice fault includes:

[0029] Obtain the rotation angle of the ice pusher;

[0030] If the rotation angle of the ice pusher is less than a preset angle threshold, the ice-removal fault is determined to be an ice pusher fault, and the ice pusher fault is reported.

[0049] Explanation of reference numerals in the attached figures: Detailed Implementation

[0050] 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.

[0051] This application provides a feedback scheme for ice maker malfunctions. To more clearly illustrate the feedback scheme for ice maker malfunctions, the following description will be provided in conjunction with the accompanying drawings. The ice maker malfunction feedback method can be executed by a processor in a terminal such as a management terminal. The ice maker can be a vertical ice maker, a horizontal ice maker, etc.

[0052] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a feedback method for ice maker malfunctions provided in an embodiment of this application.

[0053] 10. Obtain the initial temperature of the ice container before starting the ice-making process;

[0054] 20. After the ice-making process is completed, obtain the second temperature of the ice-making box;

[0055] 30. If a malfunction occurs during the ice-making process, the temperature difference between the first temperature and the second temperature is obtained.

[0056] 40. If the temperature difference value is less than the preset temperature difference threshold, the ice maker malfunction is determined to be an ice-making malfunction;

[0057] 50. If the temperature difference value is greater than or equal to the preset temperature difference threshold, the ice maker malfunction is determined to be an ice dispensing malfunction.

[0058] Specifically, the ice maker is equipped with multiple temperature sensors. Before ice making begins, the sensors acquire and store a first temperature of the ice-making space. After ice making is completed, the processor acquires and stores a second temperature of the ice-making space. The ice-making space contains ice-making components such as ice-making boxes and ice-storage boxes. The temperature sensors can obtain the temperature closest to the actual ice-making process by measuring the temperature of the ice-making components or the internal space. Therefore, the specific location of the temperature sensors is not limited in this application. If a fault occurs in the ice-making process, such as no ice being dispensed, no preset volume of ice being provided, or uneven ice dispensing rate, the temperature difference between the first and second temperatures is acquired. If the temperature difference is less than a preset temperature difference threshold, the ice maker has failed to provide a suitable temperature during the ice-making process, preventing the ice from forming properly. The ice maker fault is an ice-making fault. If the temperature difference is greater than or equal to the preset temperature difference threshold, the temperature environment during the ice-making process is normal, and the ice maker fault is an ice dispensing fault. Specifically, before ice making begins normally, a third temperature of the ice-making space is obtained. After normal ice making ends, a fourth temperature of the ice-making space is obtained. The temperature difference between the third and fourth temperatures is the preset temperature difference threshold. Since the fourth temperature is lower than the third temperature, the third and fourth temperatures are not uniquely fixed. Therefore, the absolute value of the highest temperature difference between the third and fourth temperatures can be taken as the preset temperature difference threshold. For example, if the third temperature range is 0-5℃ and the fourth temperature range is 15℃-20℃, then the preset temperature difference threshold is 20℃. Similarly, the absolute value of the temperature difference between the first and second temperatures is taken. By comparing the absolute value of the temperature difference between the first and second temperatures with the preset temperature difference threshold, the source of the ice maker malfunction can be determined. When the temperature difference is less than the preset temperature difference threshold, such as when the preset temperature difference threshold is 18℃ and the temperature difference in the ice-making space is 16℃, the ice-making space has not reached the appropriate ice-making temperature, and the ice maker malfunction is an ice-making malfunction. When the temperature difference is greater than or equal to the preset temperature difference threshold, such as when the preset temperature difference threshold is 18℃ and the temperature difference in the ice-making space is 20℃, the ice-making space has reached the ice-making temperature, that is, the ice maker has been making ice normally, and the ice maker malfunction is an ice-dispensing malfunction.

[0059] It should be noted that a malfunction in the temperature sensor itself can also lead to inaccurate test results. If the measured value is significantly higher or lower than expected, the temperature sensor may be faulty. In this case, it is necessary to check whether the temperature sensor's wiring terminals are securely connected.

[0060] For example, please refer to Figure 2 , Figure 2 for Figure 1 The diagram shows a process flow chart when an ice maker malfunctions. After determining that the ice maker malfunction is an ice-making malfunction if the difference between the first temperature and the second temperature is less than a temperature difference threshold, the process includes:

[0061] 41. Obtain the unit flow velocity at the water injection port during the water injection process;

[0062] 42. If the unit flow rate is less than the preset flow rate threshold, determine that the ice-making failure is a water injection failure, and report the water injection failure.

[0063] Specifically, the ice maker is equipped with a flow rate sensor to measure the unit flow rate at the water inlet. After ice making is completed, the processor stores the unit flow rate at the water inlet during the ice making process. If the unit flow rate is less than a preset flow rate threshold, the ice making failure is a water filling failure. The water filling failure may be caused by a disconnected water circuit, a water valve not opening properly, or insufficient water during filling. When a water filling failure occurs, the ice maker does not have enough water to make ice, resulting in a reduced ice production. The preset flow rate threshold is the minimum flow rate under normal ice making conditions.

[0064] 43. Otherwise, determine that the ice-making failure is an ice-making container deformation failure, and report the ice-making container deformation failure.

[0065] Specifically, the ice maker is equipped with a deformation detection device, which includes a detection rod and a detector. The detection rod is slidably disposed on the side wall of the ice maker. When the ice maker experiences a deformation fault, such as dent or breakage, the water storage capacity of the ice maker becomes abnormal, resulting in a reduction in the amount of ice produced.

[0066] For example, please refer to Figure 3 , Figure 3 for Figure 1 The diagram shows a flowchart illustrating the feedback process for an ice maker's ice dispensing malfunction. Determining that the ice maker malfunction is an ice dispensing malfunction includes:

[0067] 51. Obtain the volume of the ice block that entered the ice crushing chamber;

[0068] 52. If the volume is less than a preset volume threshold, the ice-out fault is determined to be an ice-removal fault;

[0069] 53. If the volume is greater than or equal to a preset volume threshold, the ice-out fault is determined to be a broken ice fault.

[0070] Specifically, the ice maker is equipped with a volume detection module. After ice is dispensed, the volume detection module can detect and store the volume of the ice cubes entering the ice crushing chamber. Under normal circumstances, the minimum volume of the ice cubes entering the ice crushing chamber is a preset volume threshold. If the volume is less than the preset volume threshold, the amount of ice before entering the ice crushing chamber is abnormal, and the ice dispensing failure is an ice separation failure. The channel between the ice crushing chamber and the ice storage box is equipped with a valve, and the ice maker is equipped with a valve switch sensor. If the switch sensor detects that the valve is not properly opened, the failure is determined to be a valve failure. If the volume is greater than or equal to the preset volume threshold, the ice cubes cannot be completely crushed after entering the ice crushing chamber, and the ice dispensing failure is an ice crushing failure.

[0071] For example, please refer to Figure 4 , Figure 4 for Figure 3 The flowchart shown illustrates the feedback process for ice detachment faults in an ice maker. Determining that the ice detachment fault is an ice detachment fault includes:

[0072] 521. Obtain the first position of the ice probe before removing the ice from the ice storage box;

[0073] 522. Obtain the second position of the ice probe after the ice block is removed from the ice storage box;

[0074] 523. If the displacement of the first position and the second position is less than a preset displacement threshold, determine that the ice separation fault is an ice probe rod fault, and report the ice probe rod fault.

[0075] Specifically, the ice maker is equipped with an ice probe rod, which rotates periodically and probes into the ice storage box. The probe rod is positioned at different locations depending on the ice content in the ice storage box. The ice maker can determine the ice content in the ice storage box based on the position of the ice probe rod, and then send back a full ice signal, causing the ice maker to control the ice storage box to release ice.

[0076] If the ice probe is in the first position before the ice is removed from the ice storage box, and after the ice is removed, the ice probe rotates into the ice storage box and is limited to the second position, in normal mode, the minimum difference between the displacement of the first and second positions of the ice probe is a preset displacement threshold. If the displacement of the first and second positions reaches the preset displacement threshold, the ice probe will send a full ice signal, and the ice will be removed normally. If the displacement of the first and second positions is less than the preset displacement threshold, it can be considered that the ice probe has malfunctioned and failed to send a full ice signal to remove the ice from the ice storage box.

[0077] For example, determining that the ice-out fault is an ice-removal fault further includes:

[0078] 524. Obtain the number of rotations of the ice-flipping stick;

[0079] 525. If the number of rotations of the ice-turning rod is less than a preset threshold number of rotations, the ice-removal fault is determined to be an ice-turning rod fault, and the ice-turning rod fault is reported.

[0080] Specifically, the ice maker also includes an ice-tumbling rod and an ice-tumbling rod motor that drives the ice-tumbling rod. The ice-tumbling rod has a number of ice-topping parts corresponding to the number of ice storage boxes. When the ice-tumbling rod motor drives the ice-tumbling rod to rotate, the ice-topping parts push out ice blocks from the corresponding ice storage boxes. If the number of rotations of the ice-tumbling rod is less than a preset rotation threshold, the ice-tumbling rod does not tumble enough, and the ice blocks in the ice storage boxes cannot completely fall into the ice crushing chamber. This ice-leaking failure is an ice-tumbling rod failure. The preset rotation threshold is the minimum number of rotations of the ice-tumbling rod under normal ice-making conditions.

[0081] For example, see example 5. Figure 5 for Figure 3 The flowchart shown is a feedback process for ice maker ice breakage faults. Determining that the ice dispensing fault is an ice breakage fault includes:

[0082] 531. Obtain the current when the ice-crushing motor is working;

[0083] 532. If the current is not within the preset current threshold range, determine that the ice crushing fault is an ice crushing motor fault, and report the ice crushing motor fault.

[0084] Specifically, the ice maker includes a current sensor. During the ice-crushing process, the processor acquires and stores the current of the ice-crushing motor. Within a preset current threshold range, the circuit of the ice-crushing motor is normal, and the ice-crushing motor operates normally. If the ice-crushing motor current is outside the preset current threshold range, the ice-crushing fault is determined to be an ice-crushing motor fault, and the fault is reported. In some embodiments, an ice blade is provided in the ice-crushing chamber, and the ice-crushing motor is used to drive the ice blade to rotate and crush ice. The ice-crushing motor fault may manifest as an ice blade fault. In this case, the ice blade speed sensor can be used to further measure the ice blade speed. If the ice blade speed is significantly lower than the normal speed, the ice-crushing fault is determined to be an ice-crushing motor fault. The preset current threshold is the minimum current of the ice-crushing motor under normal ice-making conditions.

[0085] For example, determining that the ice-out fault is a broken ice fault further includes:

[0086] 533. Obtain the rotation angle of the ice pusher;

[0087] 534. If the rotation angle of the ice pusher is less than a preset angle threshold, determine that the ice separation fault is an ice pusher fault, and report the ice pusher fault.

[0088] Specifically, the ice-pushing disc is rotatably connected to the ice storage box. The ice-pushing disc and the ice storage box are positioned above the opening of the ice crushing chamber. The ice-pushing disc is used to push ice blocks inside the ice crushing chamber into the ice outlet channel. The ice-pushing disc includes a rotating shaft, and the ice storage box can be positioned perpendicular to the rotating shaft of the ice-pushing disc. During the rotation of the ice-pushing disc, it can guide the ice blocks in contact with it to the pushing surface and push the ice blocks towards the outlet of the ice crushing chamber until the ice blocks reach the outlet. When the rotation angle of the ice-pushing disc is less than a preset angle threshold, the ice storage box cannot rotate normally to push the ice blocks out of the ice crushing chamber, resulting in a reduction in the amount of ice discharged. If the rotation angle of the ice-pushing disc is greater than or equal to the preset angle threshold, further investigation is required. In some embodiments, ice may get stuck in the ice crushing channel, i.e., the ice is not crushed satisfactorily, preventing the ice blocks from passing through the outlet. At this point, it is necessary to detect the amount of ice near the ice outlet. If the amount of ice near the ice outlet is significantly higher than the normal amount, the ice crushing fault is that the ice crushing channel is blocked. The preset angle threshold is the minimum rotation angle that the ice-making disc can rotate under normal ice-making conditions.

[0089] Please see Figure 6 , Figure 6 This is a schematic diagram of an ice maker fault feedback device provided in an embodiment of this application. This application also provides an ice maker fault feedback device 60, comprising:

[0090] 601.

If a fault occurs in the ice-making process, the temperature difference between the first temperature and the second temperature is obtained.

[0091] 602. Analysis module, used to analyze whether the temperature difference value is less than a preset temperature difference threshold.

[0092] 603. Determine the module: if the temperature difference value is less than a preset temperature difference threshold, determine that the ice maker malfunction is an ice-making malfunction;

[0093] If the temperature difference value is greater than or equal to the preset temperature difference threshold, the ice maker malfunction is determined to be an ice dispensing malfunction.

[0094] The ice maker also includes a remote monitoring module and a communication module. Users can download an application to their terminals to observe the real-time operation of the ice maker. If a malfunction occurs, the communication module can send the fault information to the user and maintenance department in real time, and provide feedback on possible causes of the malfunction after the application displays the fault code. When a specific component of the ice maker malfunctions, the communication module can send the faulty component code and time to the user and maintenance department for timely replacement. The ice maker may also include a display panel. After analyzing the cause of the malfunction, the system displays the fault type on the display panel using digital tubes. Users can then use the observed fault type code to analyze the fault types recorded in the user manual and report it to the maintenance technician. The technician can then accurately locate the fault and resolve the problem according to the maintenance manual.
