Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a refrigerator control method and a refrigerator. Background Technology

[0002] Currently, refrigeration equipment such as refrigerators are trending towards multi-compartment and finely divided storage. To ensure the requirements of multiple compartments, the industry often uses a single refrigeration system to control the temperature of multiple compartments. The core control method is to design dampers in the air ducts between the compartments, and control the temperature of different compartments by opening and closing the dampers.

[0003] Because the opening and closing of the refrigerator's damper is controlled by a control unit sending a drive signal to the damper, and all control signals from the control unit are based on a reference position (usually the damper closed), the control unit cannot identify whether the damper is in the reference position. Therefore, to ensure the damper is accurately in the reference position, it resets at fixed intervals. During the damper reset process, the control unit typically sends a full-range drive signal to the damper to ensure it is in the reference position after reset.

[0004] However, the damper may be in a non-reference position (e.g., half-open, half-closed) before resetting. This can easily lead to the damper still being controlled by extra drive signals after resetting to the reference position. The drive device that drives the damper will remain in working state, resulting in the technical problem of the refrigerator damper being over-driven during the reset process and generating abnormal noise. Summary of the Invention

[0005] The embodiments of this application provide a refrigerator control method and a refrigerator, which can at least partially solve the technical problem of abnormal noise caused by over-driving of the refrigerator damper during the reset process.

[0006] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0007] According to a first aspect of the embodiments of this application, a refrigerator control method is provided. The refrigerator includes at least two compartments, wherein a damper is disposed between two adjacent compartments, the damper being used to adjust the cold air flow between the two adjacent compartments, the damper having a reference position, and the method comprising:

[0008] When the reset waiting time of the damper meets the preset time, the damper is controlled to return to the reference position; when the damper is detected to have returned to the reference position, the damper is reset by controlling the reset movement of the damper.

[0009] In the above method, before controlling the damper's reset movement to reset the damper, the damper is controlled to return to a reference position. During the process of controlling the damper to return to the reference position, the decision to control the damper's reset movement is made by monitoring whether the damper has returned to the reference position. The advantages of this method are twofold: firstly, controlling the damper to return to the reference position facilitates control of the damper in subsequent processes; secondly, by monitoring the damper's position, the refrigerator damper can be controlled to reset precisely at the moment it returns to the reference position, thus avoiding the technical problem of abnormal noise caused by over-driving the damper during its return to the reference position.

[0010] In some embodiments of this application, based on the foregoing scheme, the reference position includes a closed limit position. Before controlling the damper to return to the reference position, when the damper is detected to be in the closed limit position, the reset waiting time of the damper is cleared so as to re-record the reset waiting time of the damper.

[0011] In the above embodiment, before controlling the damper to return to the reference position, when the damper is detected to be in the closed limit position, the reset waiting time of the damper is re-recorded. In this way, the damper does not need to be reset, thereby saving damper reset resources and ensuring that the refrigerator does not generate noise due to the damper reset movement.

[0012] In some embodiments of this application, based on the foregoing scheme, the reference position includes a closed limit position and an open limit position. When the damper is detected to return to the closed limit position, the damper is controlled to open from the closed limit position to the open limit position; when the damper is opened to the open limit position, the damper is controlled to close from the open limit position to the closed limit position.

[0013] In the above embodiment, when the damper is detected to have returned to the closed limit position, the damper is controlled to first open from the closed limit position to the open limit position, and then close from the open limit position to the closed limit position. The advantage of this is that by controlling the damper's reset motion based on the detected closed limit position, it can be ensured that the full-range drive signal sent to the damper for reset will not have excessive drive signal, thereby ensuring that the refrigerator damper will not be over-driven and generate abnormal noise during the reset process.

[0014] In some embodiments of this application, based on the foregoing scheme, the reference position includes a closed limit position and an open limit position. When the damper is detected to return to the open limit position, the damper is controlled to close from the open limit position to the closed limit position.

[0015] When the damper is detected to have returned to the open limit position, the damper is controlled to close from the open limit position to the closed limit position. The advantage of this is that by controlling the damper's reset movement based on the detected open limit position, it is also possible to ensure that the full-range drive signal sent to the damper for reset will not have an excessive drive signal, thereby ensuring that the refrigerator damper will not be over-driven and generate abnormal noise during the reset process.

[0016] In some embodiments of this application, based on the foregoing scheme, after controlling the damper to close from the open limit position to the closed limit position, when the damper is detected to have closed to the closed limit position, the reset movement of the damper is controlled to be terminated; if the damper is not detected to have closed to the closed limit position within a predetermined time, the reset movement of the damper is controlled to be terminated.

[0017] In the above embodiments, on the one hand, during the reset movement of the damper, by monitoring whether the damper is closed to the closing limit position, the reset movement of the damper can be controlled to be terminated, thereby ensuring that the refrigerator damper is not over-driven during the reset process and generates abnormal noise. On the other hand, to prevent malfunctions in monitoring whether the damper is closed to the closing limit position (e.g., monitoring failure), a predetermined time is set. That is, if the damper is not detected to be closed to the closing limit position within the predetermined time, the reset movement of the damper is also controlled to be terminated. In this way, it can be further ensured that the refrigerator damper is not over-driven during the reset process and generates abnormal noise.

[0018] According to a second aspect of the embodiments of this application, a refrigerator employing the above-described refrigerator control method is provided, the refrigerator comprising:

[0019] At least two compartments are used to form a low-temperature storage space;

[0020] A damper is used to regulate the airflow between two adjacent compartments.

[0021] A drive unit is used to drive the damper to open or close;

[0022] A monitoring device is used to monitor the opening and closing status of the damper;

[0023] And a control unit, used to control the drive device to drive the damper to open or close according to the opening and closing state of the damper.

[0024] In some embodiments of this application, the driving device includes a stepper motor, and the control unit drives the damper to complete the reset movement by controlling the number of steps of the stepper motor.

[0025] In some embodiments of this application, the monitoring device includes a tactile switch disposed on the damper.

[0026] In the refrigerator described above, a tactile switch installed on the damper is used as a monitoring device to monitor the opening and closing status of the damper. Its advantages are that the monitoring accuracy is high, and the tactile switch is inexpensive, easy to maintain, and easy to promote.

[0027] In some embodiments of this application, the damper includes a damper panel and a damper frame, the tactile switch is disposed at the edge of the damper frame, and when the damper is in the closed limit position, the damper panel is in close contact with the edge of the damper frame.

[0028] In the refrigerator described above, the tactile switch is positioned at the edge of the damper frame. When the damper door panel presses against the tactile switch, the tactile switch sends a signal indicating that the damper is in the closed limit position. It can be seen that positioning the tactile switch at the edge of the damper frame can improve the accuracy of the tactile switch in detecting whether the damper is closed to the closed limit position.

[0029] According to a third aspect of the embodiments of this application, a computer-readable non-volatile storage medium is provided, including a computer-readable program or instructions, which, when read and executed by a computer, cause the computer to perform the methods described in the first aspect and the various embodiments of the first aspect.

[0030] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0038] 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 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.

[0039] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0040] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0041] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0042] Figure 1 This is a schematic diagram of a refrigerator system architecture provided in an embodiment of this application. The system architecture can be a refrigerator 100, which can include a damper 101 and a drive device 102.

[0043] The damper 101 is used to adjust and control the temperature of each compartment of the refrigerator, and the drive device 102 is used to drive the damper 101 to open or close, thereby controlling the opening and closing state of the damper and thus adjusting and controlling the temperature of each compartment of the refrigerator.

[0044] In this application, the working principle of the damper is to control the convection of cold air in each room by opening or closing the damper, thereby achieving the effect of regulating the temperature.

[0045] Based on the above description Figure 2 The present application provides a detailed schematic diagram of the steps of a refrigerator control method according to an embodiment of the present application. The steps can be executed by the refrigerator's control unit, which can be located inside the control device or is the refrigerator's control device itself.

[0046] Therefore, the following is combined with Figure 2 This application describes in detail a refrigerator control method provided by an embodiment. The refrigerator includes at least two compartments, wherein a damper is provided between two adjacent compartments. The damper is used to adjust the cold air flow between the two adjacent compartments, and the damper has an extreme position. The control method includes steps 210 to 230:

[0047] In step 210, when the reset waiting time of the damper meets the preset time, the damper is controlled to return to the extreme position.

[0048] In this application, the reset waiting time refers to the time interval between the damper's last reset. For example, the preset time is set to 1 hour. When the damper's reset waiting time reaches 1 hour, the damper is controlled to return to its limit position by sending a drive control command to the drive device.

[0049] In one optional embodiment of step 210, the limit position includes a closed limit position, which refers to the position of the damper when it is fully closed. When the damper is detected to be in the closed limit position, the reset waiting time of the damper is cleared so as to re-record the reset waiting time of the damper.

[0050] In this application, the closed limit position refers to the position of the damper when it is fully closed.

[0051] In this application, before the damper is controlled to return to its limit position, the actual position of the damper is monitored. When the damper is detected to be in the closed limit position, the reset waiting time of the damper is cleared. For example, before the damper is detected to be in the closed limit position, the reset waiting time of the damper is 49 minutes. When the damper is detected to be in the closed limit position, the reset waiting time is cleared to zero and the reset waiting time is started again.

[0052] In step 230, when the damper is detected to have returned to the extreme position, the damper is reset by controlling the reset movement of the damper.

[0053] In this application, the purpose of resetting the damper is to accurately control the position of the damper so as to accurately adjust the temperature of each compartment of the refrigerator by precisely adjusting the opening and closing degree of the damper.

[0054] In one optional embodiment of step 230, the limit position includes a closed limit position and an open limit position. When the damper is detected to return to the closed limit position, the damper is controlled to open from the closed limit position to the open limit position; when the damper is opened to the open limit position, the damper is controlled to close from the open limit position to the closed limit position.

[0055] In this application, the open limit position refers to the position of the damper when it is fully open.

[0056] In this application, the damper reset can be based on the damper's closed limit position. The reset process based on the damper's closed limit position can be divided into two parts: the first part is the damper reset opening, and the second part is the damper reset closing. To ensure full-stroke reset of the damper, the reset rule can be to first send a full-stroke opening signal to the drive device (reset opening process), causing the drive device to drive the damper to fully open; then, by sending a closing signal greater than the full stroke to the drive device (reset closing process), causing the drive device to drive the damper to fully close.

[0057] It should be noted that sending a closing signal greater than the full stroke to the drive unit is to ensure that the drive unit drives the damper to complete closure.

[0058] In one optional embodiment of step 230, the limit position includes a closed limit position and an open limit position. When the damper is detected to return to the open limit position, the damper is controlled to close from the open limit position to the closed limit position.

[0059] In this application, the damper can also be reset based on its opening limit position. Resetting the damper based on its opening limit position can involve only one part: the damper reset and closing. Specifically, this is achieved by sending a closing signal (reset and closing process) greater than the full stroke to the drive device, causing the drive device to fully close the damper.

[0060] In the above-mentioned optional embodiments, after controlling the damper to close from the open limit position to the closed limit position, when the damper is detected to be closed to the closed limit position, the reset movement of the damper is terminated; if the damper is not detected to be closed to the closed limit position within a predetermined time, the reset movement of the damper is terminated.

[0061] On one hand, when the damper is detected to be closed to its maximum closing position, the reset movement of the damper is terminated. Since the damper is fully closed during the reset process based on a closing signal exceeding the full stroke sent to the drive device, there may still be excess closing signals even when the damper is fully closed, meaning the damper is still being driven. Therefore, by terminating the drive device's operation when the damper is detected to be at its maximum closing position during the reset process, the reset movement of the damper can be controlled and terminated. This ensures that the refrigerator damper is not over-driven during the reset process, preventing abnormal noise.

[0062] On the other hand, if the damper is not detected to be closed to the closing limit position within a predetermined time, the reset movement of the damper is terminated.

[0063] To prevent malfunctions in monitoring whether the damper is closed to its limit position, such as monitoring failure (i.e., the damper is already in the limit position but is not detected), a predetermined time is set. If the damper is not detected to be closed to its limit position within the predetermined time, the reset movement of the damper is also controlled to terminate. In this way, it can be further ensured that the refrigerator damper will not be over-driven and generate abnormal noise during the reset process.

[0064] In one embodiment of this application, the driving device for resetting the damper can be a stepper motor. Therefore, the predetermined time can be measured by the number of steps of the stepper motor, that is, the predetermined time is represented by a predetermined number of stepper motor steps. Specifically, if the damper is not detected to be closed to the closing limit position within the predetermined number of stepper motor steps (predetermined time), the reset movement of the damper is terminated. For example, if the damper is not detected to be closed to the closing limit position within the time corresponding to 2000 stepper motor steps, the reset movement of the damper is terminated.

[0065] To better explain the embodiments of this application, the following will be combined with Figure 3 The embodiments of this application will be described in general using a specific implementation scenario:

[0066] Figure 3 A detailed flowchart illustrating a refrigerator control method provided in an embodiment of this application is shown below. Figure 3 As shown, the process specifically includes:

[0067] Step 301: When the damper reset waiting time reaches the preset time, the damper reset procedure is started.

[0068] Step 302: Check if the tactile switch is closed. If yes, proceed to step 303; otherwise, proceed to step 304.

[0069] Step 303: Clear the damper reset waiting time and skip this reset.

[0070] Step 304: Send a control command to the drive unit to close the damper.

[0071] Step 305: Check if the tactile switch is closed. If yes, proceed to step 306; otherwise, proceed to step 304.

[0072] Step 306: Send a full-process drive control command to the drive unit to open the damper.

[0073] Step 307: Send a full-process drive control command to the drive unit to close the damper.

[0074] Step 308: Check if the tactile switch is closed. If yes, proceed to step 309; otherwise, proceed to step 307.

[0075] Step 309: Complete the damper reset.

[0076] The specific implementation methods of the above process have been described in the above embodiments and will not be repeated here.

[0077] Based on the same technological concept Figure 4 An exemplary system architecture for a refrigerator provided in an embodiment of this application is shown, which can perform the refrigerator control method as described above.

[0078] like Figure 4 As shown, the refrigerator specifically includes:

[0079] At least two compartments (not shown in the diagram) are used to form a cryogenic storage space;

[0080] Damper 401 is used to adjust the airflow between the two adjacent compartments;

[0081] Drive device 402 is used to drive the damper to open or close;

[0082] Monitoring device 404 is used to monitor the opening and closing status of the damper;

[0083] And control unit 403, used to control the drive device to drive the damper to open or close according to the opening and closing state of the damper.

[0084] In one alternative embodiment, the driving device includes a stepper motor, and the control unit drives the damper to complete the reset movement by controlling the number of steps of the stepper motor.

[0085] For example, if the number of steps required for the damper to fully open and close is 1750, when the reset begins, the control unit can provide the stepper motor with an opening signal of 1750 steps. When the damper is fully open, the control unit can provide the stepper motor with a closing signal of 1850 steps. In this way, no matter what position the damper is in before the reset, it can be guaranteed that the damper can be opened and closed.

[0086] It should be noted that when the damper is fully open, the control unit can provide the stepper motor with a closing signal of 1850 steps. The purpose of this is to prevent the stepper motor from missing steps during the process of driving the damper to close (through verification, the number of steps to close the damper is 0-100 more than the required number of steps without producing obvious abnormal noise).

[0087] In one alternative embodiment, the monitoring device includes a tactile switch disposed on the damper.

[0088] In one alternative embodiment, the damper includes a damper panel and a damper frame, and the tactile switch is located at the edge of the damper frame. When the damper is in the closed limit position, the damper panel is in close contact with the edge of the damper frame.

[0089] Specifically, a tactile switch can be a surface-mount tactile switch. A surface-mount tactile switch consists of normally open and normally closed contacts. In a surface-mount tactile switch, the function of the normally open contact is to connect the circuit when pressure is applied to it, and to disconnect the circuit when the pressure is removed, returning it to its original normally closed state. The internal structure of a surface-mount tactile switch relies on metal springs to protect against stress, thereby achieving the switching on and off.

[0090] To enable those skilled in the art to better understand this embodiment, the following description is provided in conjunction with... Figure 5-A and Figure 5-B The location of the tactile switch on the damper is explained;

[0091] like Figure 5-A and Figure 5-B These are the front view and top view of the refrigerator door structure 500 in the open state.

[0092] A surface-mount tactile switch 503 is installed at the midpoint between the damper panel 501 and the damper frame 502. When the damper 500 is closed, the damper panel 501 applies pressure to the tactile switch 503, causing it to close. The control unit detects the closed state of the tactile switch 503 and determines that the damper 500 is closed. If the damper panel 501 is not closed, the tactile switch 503 is not subjected to pressure, and the control unit detects that the tactile switch 503 is open, thus determining that the damper 500 is open. In this way, the opening and closing of the surface-mount tactile switch 503 can be used to determine whether the damper 500 is closed.

[0093] For those skilled in the art, provided that the opening and closing status of the damper can be monitored, the tactile switch can also be set in other locations on the damper.

[0094] In this application, a damper that can sense the closed state of the damper is designed by using a tactile switch. When it is necessary to control the damper, the closed state of the damper can be used as a reference to control the damper more accurately.

[0095] In addition, the tactile switch can also sense the closed state of the damper. Before the damper resets, it can detect whether it is in a closed state (the reference position to be reached for reset), which can effectively reduce the number of times the damper resets, so as to reduce the number of times damper reset noise occurs.

[0096] During the reset process, when the tactile switch is detected to be closed (i.e., the door panel is closed), the control unit controls the stepper motor to stop driving the damper door panel to close, thereby avoiding the stepper motor from overstepping and generating abnormal noise.

[0097] It should be noted that the monitoring device may also include other devices, and is not limited to the tactile switch described above.

[0098] In one optional embodiment, the control unit 403 is configured to: control the damper to return to the extreme position when the reset waiting time of the damper meets a preset time; and reset the damper by controlling the reset movement of the damper when the damper is detected to have returned to the extreme position.

[0099] In one alternative embodiment, the control unit 403 is configured to: before controlling the damper to return to the limit position, upon detecting that the damper is in the closed limit position, clear the reset waiting time of the damper to re-record the reset waiting time of the damper.

[0100] In one optional embodiment, the limit positions include a closed limit position and an open limit position, and the control unit 403 is configured to: when the damper is detected to return to the closed limit position, control the damper to open from the closed limit position to the open limit position; and when the damper is opened to the open limit position, control the damper to close from the open limit position to the closed limit position.

[0101] In one alternative embodiment, the limit positions include a closed limit position and an open limit position, and the control unit 403 is configured to: when the damper is detected to return to the open limit position, control the damper to close from the open limit position to the closed limit position.

[0102] In one alternative embodiment, the control unit 403 is configured to: after controlling the damper to close from the open limit position to the closed limit position, when the damper is detected to be closed to the closed limit position, control to terminate the reset movement of the damper; and if the damper is not detected to be closed to the closed limit position within a predetermined time, control to terminate the reset movement of the damper.
