[0002] As refrigerator functionality improves, more and more refrigerators are adding adjustable temperature zones within the refrigerator compartment. When the temperature zone and refrigerator compartment are controlled separately using two separate display panels, a temperature display panel is installed within the refrigerator compartment to adjust the temperature zone settings, requiring the user to open the door before making adjustments. However, this presents a problem: after closing the refrigerator door, the user must periodically open the door to check whether the current temperature zone setting matches the preset setting.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0027] In order to solve the problem in the prior art that after the refrigeration door is closed, the user needs to open the refrigerator door at intervals to check whether the current state of the variable temperature chamber is consistent with the previously preset state, the present application provides a refrigerator control method. First of all, it should be explained that the refrigerator in the present application includes an inner display panel, a main board, and an outer display panel. Among them, the inner display panel can independently control the state of the variable temperature chamber, that is, after the user sets the operating state of the variable temperature chamber on the inner display panel, the inner display panel sends the control parameters of the operating state to the main board, and the main board controls the operating state of the variable temperature chamber in the refrigerator, and then displays the operating state of the variable temperature chamber currently set by the inner display panel on the outer display panel. Based on this, Figure 1 As shown, the method in the embodiment of the present application includes:

[0028] Step 101: When the refrigerator door is closed for a period exceeding a first preset period, the real-time temperature of the variable temperature chamber of the refrigerator is obtained; wherein, after the refrigerator door is closed, the internal display panel for controlling the variable temperature chamber in the refrigerator is disconnected from the main board in the refrigerator;

[0029] In the embodiment of the present application, the first preset duration can be set accordingly based on actual needs, such as 6 hours, 8 hours, 12 hours, etc. Since the internal display panel for controlling the variable temperature chamber in the refrigerator is disconnected from the main board in the refrigerator after the refrigerator door is closed, the operating state of the variable temperature chamber may have deviated from the initial target operating state over time, that is, it may be inconsistent with the operating state before the door was closed. The reason for this may be the influence of other compartments or a malfunction of the variable temperature chamber itself.

[0030] In addition, in the embodiment of the present application, the temperature of the variable temperature chamber can be acquired by a set temperature sensor, and the position of the temperature sensor can be set accordingly according to the needs. That is, in the present application, the real-time temperature of the variable temperature chamber can be acquired by the temperature sensor in real time.

[0031] Step 102, when the real-time temperature is not within the preset temperature range, the internal display panel of the refrigerator is controlled to communicate with the main board again when the refrigerator is in the closed state, and an instruction for controlling the variable temperature chamber to operate in the target operating state is sent to the main board through the internal display panel, so that the real-time temperature of the variable temperature chamber falls within the preset range, wherein the target operating state is the state in which the internal display panel controls the variable temperature chamber to operate before the refrigerator is closed, and the preset temperature range matches the target operating state.

[0032] In this regard, in a specific example, the preset temperature range may refer to a range of temperatures corresponding to a certain operating state. For example, if the current operating state is state A, the operating temperature of the corresponding controlled variable temperature chamber is -5°C to 5°C, and the corresponding preset temperature range is -5°C to 5°C. If the current operating state is state B, the operating temperature of the corresponding controlled variable temperature chamber is 2°C to 10°C, and the corresponding preset temperature range is 2°C to 10°C. Taking the target operating state as state A as an example, before the refrigerator door is closed, the operating state of the variable temperature chamber is state A. After a first preset time (such as 12 hours), if the real-time temperature of the variable temperature chamber obtained is within -5°C to 5°C, it indicates that the current variable temperature chamber is operating normally. If the real-time temperature of the variable temperature chamber is not within -5°C to 5°C, it indicates that the operating state of the variable temperature chamber is abnormal and needs to be self-corrected. Therefore, in this application, the inner display panel and the main board need to communicate and connect again when the refrigerator door is closed, and then the inner display panel automatically sends an instruction for controlling the variable temperature chamber in state A to the main board. After receiving the instruction, the main board controls its variable temperature chamber. If the current real-time temperature is lower than -5°C, the temperature of the variable temperature chamber is increased. If the current real-time temperature of the variable temperature chamber is higher than 5°C, the temperature of the variable temperature chamber is lowered to return the temperature of the variable temperature chamber to the range of -5°C to 5°C.

[0033] It can be seen that through the above steps 101 to 102 of the embodiment of the present application, after the refrigerator door is closed for the first preset period of time, it is possible to determine whether the current variable temperature chamber needs to be self-corrected by obtaining the real-time temperature of the variable temperature chamber and comparing it with the preset temperature range. That is, if the current real-time temperature is not within the preset temperature range, it is necessary to re-establish the communication connection between the inner display panel and the outer display panel with the refrigerator door closed. The inner display panel sends the instruction for controlling the variable temperature chamber to operate in the target operating state to the main board, and the main board controls the temperature of the variable temperature chamber to return to the preset temperature range, thereby realizing self-correction of the variable temperature chamber. There is no need for the user to open the refrigerator again for manual adjustment, so that the refrigerator can operate stably in the required state even when no one is around. That is, there is no need for the user to manually open the refrigerator door to confirm the state of the variable temperature chamber, which solves the problem in the prior art that after the refrigeration door is closed, the user needs to open the refrigerator door at intervals to check whether the current state of the variable temperature chamber is consistent with the previously preset state.

[0034] In this embodiment of the present application, the refrigerator temperature change chamber state can be self-corrected at intervals of a first preset time. However, the self-correction process may not be able to correct the temperature in one go, and multiple self-corrections may be required to restore the temperature of the temperature change chamber to within the preset temperature range. Based on this, the method of sending an instruction for controlling the target operating state of the temperature change chamber to the main board via the internal display panel in step 102 so that the real-time temperature of the temperature change chamber falls within the preset range may further include:

[0035] Step 11, after the inner display panel sends the instruction to the main board, the variable temperature room is controlled to operate in the target operating state, and the communication between the inner display panel and the main board is disconnected;

[0036] Step 12, after the variable temperature chamber operates in the target operating state for a second preset time, obtaining the real-time temperature of the variable temperature chamber again;

[0037] Step 13, when the real-time temperature obtained again is closer to the preset temperature range than the real-time temperature obtained previously, the internal display panel is controlled to communicate with the main board again, and instructions are sent to the main board again through the internal display panel to continue controlling the target operating state of the variable temperature chamber so that the real-time temperature of the variable temperature chamber falls within the preset range.

[0038] In the embodiment of the present application, the second preset duration is shorter than the first preset duration. Typically, the first preset duration is longer, such as 6 hours or 8 hours, while the first preset duration is 1 hour or 2 hours. Therefore, the second preset duration is used to verify that the temperature of the variable temperature chamber is not within the preset temperature range, and after the communication connection is reestablished with the main board via the internal display panel, the temperature of the variable temperature chamber is self-corrected. If the second preset duration is too long and the variable temperature chamber currently experiences a fault, the fault cannot be reported in a timely manner. Therefore, it is necessary to set an appropriate second preset duration so that the status of the variable temperature chamber after the current self-correction can be obtained in a timely manner.

[0039] For the above steps 11 to 13, taking the second preset time of 1 hour as an example, the current preset temperature range is -5℃~5℃. If the current temperature of the variable temperature chamber is 10℃ after the first preset time (12 hours), it is necessary to re-establish the communication connection between the internal display panel and the main board, and then send an instruction to control the variable temperature chamber to operate in the target operating state through the internal display panel. After the main board receives the instruction, it controls the variable temperature chamber to operate in the target operating state again. After 1 hour, the real-time temperature of the variable temperature chamber is obtained again. If the real-time temperature at this time is 7℃, it is still not within the range of -5℃~5℃. Therefore, it is necessary to perform self-correction of the variable temperature chamber again, that is, the internal display panel and the main board communicate again, and send instructions to the main board through the internal display panel to continue to control the variable temperature chamber to operate in the target operating state, so that the real-time temperature of the variable temperature chamber falls within the preset range.

[0040] In different application scenarios, it may only take one second preset time to complete the self-correction, while in other application scenarios, it may take multiple second preset time periods to complete the self-correction. That is to say, the above steps 11 to 13 are a cyclic self-correction process. It is possible that although the current real-time temperature is not within the preset temperature range, if the preset temperature range is -5℃~5℃ and the current real-time temperature is less than 7℃, it may only take one second preset time period (such as 1 hour) to complete the self-correction. If the current real-time temperature is less than 10℃, it may take two second preset time periods. If the current real-time temperature deviates more, it may take more second preset time periods. It can be seen that in the embodiment of the present application, for the self-correction process of the variable temperature room, the user does not need to manually open the refrigerator to adjust it, but it is automatically completed when the refrigerator door is not opened.

[0041] During the self-correction process, it is possible that after a second preset time, the real-time temperature is close to the preset temperature range. For example, if the preset temperature range is -5°C to 5°C and the current real-time temperature is -10°C, after a second preset time (such as 1 hour) of self-correction, the real-time temperature is -8°C. After a second second preset time, that is, two hours later, the real-time temperature becomes -10°C again. Then, after a third second preset time, that is, three hours later, the real-time temperature becomes -12°C, that is, the real-time temperature is getting further and further away from the preset temperature range. This indicates that the temperature change chamber may be faulty. Based on this, the method of the embodiment of the present application may also include:

[0042] Step 21, when the real-time temperature obtained again is farther away from the preset temperature range than the real-time temperature obtained previously, the internal display panel is controlled to communicate with the main board again, and a fault prompt is sent to the main board through the internal display panel, and the fault prompt is displayed on the external display panel of the refrigerator.

[0043] As can be seen, in the embodiment of the present application, if the current real-time temperature is not within the preset temperature range, the variable temperature chamber will be self-corrected. However, self-correction can only correct temperature fluctuations in the variable temperature chamber caused by factors in other compartments, and cannot self-correct faults in the variable temperature chamber itself. Therefore, after one or more self-corrections, if the temperature of the variable temperature chamber still does not fall within the preset temperature range, it indicates that the variable temperature chamber may be faulty and the temperature cannot be corrected through self-correction. Therefore, it is necessary to remind the user that the variable temperature chamber may be faulty.

[0044] In an embodiment of the present application, when the real-time temperature of the variable temperature chamber is not within the preset temperature range, it indicates that the temperature of the variable temperature chamber needs to be self-corrected. In the above steps 11 to 13, during the self-correction process, the real-time temperature is obtained every first preset time to determine whether the current self-correction is completed. However, in the actual self-correction process, although the temperature is close to the preset temperature range, the rate of approach is slow. For example, the current preset temperature range is -5℃ to 5℃, and the real-time temperature of the variable temperature chamber is -15℃. If the above steps 11 to 13 are performed with the first preset time of 1 hour, the self-corrected temperature is usually 8℃ within an hour, that is, it should be -7℃ after one hour. However, if the real-time temperature of the variable temperature chamber is -12℃ at this time, it indicates that although the temperature is close to the preset temperature range, the rate of approach is slow, which is not a normal heating rate. Therefore, it can also be determined that the current variable temperature chamber has a fault to alert the user. The above heating rate is only an example. In specific application scenarios, it can be set accordingly according to actual needs. Based on this, the method involved in step 102 of sending an instruction for controlling the target operating state of the variable temperature chamber to the main board through the internal display panel so that the real-time temperature of the variable temperature chamber falls within a preset range may further include:

[0045] Step 31, after the inner display panel sends the instruction to the main board, the variable temperature room is controlled to operate in the target operating state, and the communication between the inner display panel and the main board is disconnected;

[0046] Step 32, after the variable temperature chamber operates in the target operating state for a second preset time, obtaining again the rate of change of the real-time temperature of the variable temperature chamber within the second preset time;

[0047] Step 33, when the rate of change is greater than the first preset threshold and less than the second preset threshold, and the real-time temperature of the variable temperature chamber is close to the preset temperature range, the internal display panel is controlled to communicate with the main board again, and instructions are sent to the main board again through the internal display panel to continue controlling the target operating state of the variable temperature chamber so that the real-time temperature of the variable temperature chamber falls within the preset range.

[0048] In an embodiment of the present application, the second preset time length is usually shorter than the first preset time length, such as the second preset time length is 20min, 30min, so that the temperature change rate during the current self-correction process can be obtained in a timely manner. In addition, in an embodiment of the present application, during the self-correction process, a temperature change rate that is too small or too high may be a fault in the variable temperature chamber. It is more reasonable only if the temperature changes within a stable and appropriate range. Taking the second preset time length as 30min, under normal circumstances, the cooling rate should be 5℃ / 30min, and the heating rate should be 4℃ / 30min. Of course, the above is only an example, and the specific reasonable heating and cooling rates can be set accordingly according to actual needs. Based on this, the method of the embodiment of the present application also includes:

[0049] Step 41, when the rate of change is less than or equal to the preset threshold, or the rate of change is greater than or equal to the second preset threshold, the internal display panel is controlled to communicate with the main board again, and a fault prompt is sent to the main board through the internal display panel, and the fault prompt is displayed on the external display panel of the refrigerator.

[0050] It can be seen that in the embodiment of the present application, for the temperature change rate during the self-correction process, too large or too small may be an abnormal situation. At this time, although the temperature is close to the preset temperature range, too slow or too fast approach may be caused by a malfunction of the temperature changing chamber itself. Therefore, the user needs to be reminded in this situation.

[0051] In the embodiment of the present application, in order to ensure that the mainboard obtains the control parameters of the inner display panel before the refrigerator door is closed, that is, the user sets the parameters of the variable temperature chamber through the inner display panel when the refrigerator door is opened, the communication connection between the inner display panel and the mainboard can be disconnected after determining that the mainboard has received the control parameters of the inner display panel. Therefore, the method of the embodiment of the present application further includes:

[0052] Step 51: When the refrigerator door is detected to be closed, the control main board obtains the control parameters of the internal display board currently controlling the temperature-changing chamber;

[0053] Step 52: After the control parameters are acquired, the control main board disconnects the communication with the internal display board.

[0054] After the refrigerator door is closed, in order to save energy, the communication between the internal display panel and the main board will be disconnected. However, if the communication between the two is disconnected immediately after the refrigerator door is closed, it is possible that the control parameters on the internal display panel have not been completely sent to the main board, and the communication between the two is disconnected, resulting in the control parameters of the internal display panel not being completely sent to the main board. Therefore, in this application, it is necessary to ensure that the communication between the two will be disconnected only after the main board has completely obtained the parameters of the internal display panel. In a specific example, the following two methods can be used to determine whether the main board has completed obtaining the control parameters: 1) After the refrigerator door is closed, the time for the communication between the internal display panel and the main board to be disconnected is delayed. For example, the communication was disconnected after the refrigerator door was closed before. In this application, the delay can be 3s to 5s or even longer, depending on the specific situation. 2) The main board can directly display whether the control parameters have been received. After completion, there will be a prompt sound or display, and then the communication between the two will be disconnected. Through the method of the embodiment of the present application, although there may be delays sometimes, the accurate delivery of the control parameters between the two is guaranteed, and no waste of energy is caused.

[0055] The present application is described below with reference to a specific embodiment of the present application. The specific embodiment provides an operation control method for a display panel inside a refrigerator. Figure 2 As shown in the internal display panel, the default function when the refrigerator is powered on is fruits and vegetables. When the user needs to adjust a function, the user opens the refrigerator door, unlocks the display panel, clicks on the function to be adjusted, and then closes the refrigerator door. However, in the prior art, in order to reduce the power consumption of the refrigerator, the communication between the internal display panel and the main board is immediately disconnected after the refrigerator door is closed to avoid the increase in power consumption caused by frequent communication. However, the communication time between the display panel and the main board is about 2-5 seconds. If the user closes the door immediately after adjusting the function, the display panel will be powered off and the function will be powered off without transmitting a signal to the main board. As a result, the next time the user opens the door, they will find that the function is not adjusted by themselves. In this regard, in this application, the power-off time of the display panel can be set to delay the disconnection of the communication between the main board and the temperature-variable display panel until 5 seconds after the refrigerator door is closed. This can not only reduce power consumption when closing the door, but also prevent the problem of adjustment functions not being remembered.

[0056] In addition, if Figure 3 As shown, the operation control method of the display panel inside the refrigerator includes:

[0057] Step 301, detecting that the refrigerator door is closed and recording the functional status at this time;

[0058] Step 302, start timing t;

[0059] Step 303, determine whether t is greater than or equal to 24h, if yes, go to step 304, if not, go to step 302;

[0060] Step 304, determine whether the function is consistent with the last time the door was closed; if not, proceed to step 305, if yes, proceed to step 306;

[0061] Step 305, the internal display panel self-corrects to the last function;

[0062] Step 306, normal operation.

[0063] Through the above steps 301 to 306, if the user goes away and the refrigerator door is not opened for a long time, the variable temperature display panel is in a communication-disconnected state for a long time, and it is impossible to detect whether the variable temperature chamber is operating normally according to the set function. Self-correction can be completed in the following manner through the embodiment of the present application: Each time the user closes the door, the main board memorizes the functional state of the variable temperature display panel before the communication is disconnected. When the refrigerator door is not detected to be open for 24 hours, the variable temperature display panel and the main board force a signal communication once to detect the functional state at this time and compare it with the function after the last door was closed. If they are consistent, the power is turned off to reduce energy consumption. If they are inconsistent, the variable temperature display panel self-corrects to the functional operation after the last door was closed.

[0064] like Figure 4 As shown, the operation control method of the display panel inside the refrigerator includes:

[0065] Step 401, detecting that the refrigerator door is closed and recording the functional status at this time;

[0066] Step 402, recording the temperature T of the variable temperature sensor;

[0067] Step 403, calculating the start point T1 and the stop point T2 of this function;

[0068] Step 404, determine whether T is greater than or equal to T1+3, or whether T is less than or equal to T2-3; if yes, proceed to step 405, if not, proceed to step 402;

[0069] Step 405, the internal display panel self-corrects to the last function;

[0070] Step 406, determine whether T is greater than or equal to T1+3 again, or whether T is less than or equal to T2-3; if yes, proceed to step 407, if not, proceed to step 408;

[0071] Step 407: transmitting a signal to the external display panel to indicate a temperature change room failure;

[0072] Step 408, normal operation.

[0073] For the above steps 401 to 408, combined with a specific example, it can be: the main board memorizes the functional status after the last door is closed, and derives the start and stop points of the variable temperature room according to the operating logic, and then detects the temperature of the variable temperature room temperature sensor at this time every 6 hours to see if it is within the start and stop point range. If it is, it proves that the temperature of the variable temperature room is normal at this time. If it is 3°C higher than the start point or 3°C lower than the stop point, it means that the variable temperature function is incorrect or the damper is operating properly. The variable temperature display board first self-corrects to the functional operation after the last door is closed, and detects the temperature of the variable temperature sensor at this time after running for 2 hours. If the temperature difference from the start and stop points becomes smaller, continue to run for 2 hours and then detect again until the temperature is normal; if the temperature difference does not improve significantly or becomes larger and larger, it indicates that the variable temperature room of the external display board has a fault, and prompts the user to contact after-sales maintenance. Since the internal display board and the external display board have no communication, the internal display board sends a fault prompt to the host, and then the main board sends the corresponding fault code to the external display board.

[0074] Corresponding to Figure 1 , the embodiment of the present application also provides a refrigerator control device, such as Figure 5 As shown, the device includes:

[0075] An acquisition module 502 is configured to acquire the real-time temperature of the variable temperature chamber of the refrigerator when the refrigerator door is closed for a period exceeding a first preset period. After the refrigerator door is closed, the internal display panel for controlling the variable temperature chamber is disconnected from the main board of the refrigerator.

[0076] The first processing module 504 is used to control the internal display panel of the refrigerator to communicate with the main board again when the refrigerator is in a closed state when the real-time temperature is not within the preset temperature range, and to send an instruction for controlling the variable temperature chamber to operate in a target operating state to the main board through the internal display panel, so that the real-time temperature of the variable temperature chamber falls within the preset range, wherein the target operating state is the state in which the internal display panel controls the variable temperature chamber to operate before the refrigerator is closed, and the preset temperature range matches the target operating state.

[0077] Through the device of the embodiment of the present application, after the refrigerator door is closed for a first preset period of time, it is possible to determine whether the current variable temperature chamber needs to be self-corrected by obtaining the real-time temperature of the variable temperature chamber and comparing it with the preset temperature range. That is, if the current real-time temperature is not within the preset temperature range, it is necessary to re-establish the communication connection between the inner display panel and the outer display panel when the refrigerator door is closed. The inner display panel sends the instruction for controlling the variable temperature chamber to operate in the target operating state to the main board, and the main board controls the temperature of the variable temperature chamber to return to the preset temperature range, thereby realizing self-correction of the variable temperature chamber. There is no need for the user to open the refrigerator again for manual adjustment, so that the refrigerator can operate stably in the required state even when no one is around. That is, there is no need for the user to manually open the refrigerator door to confirm the state of the variable temperature chamber, which solves the problem in the prior art that after the refrigeration door is closed, the user needs to open the refrigerator door at intervals to check whether the current state of the variable temperature chamber is consistent with the previously preset state.

[0078] In an optional implementation manner of an embodiment of the present application, the first processing module in the embodiment of the present application may further include: a first control unit, for controlling the target operating state of the variable temperature chamber to operate and disconnecting the communication between the inner display panel and the main board after the inner display panel sends an instruction to the main board; a first acquisition unit, for obtaining the real-time temperature of the variable temperature chamber again after the variable temperature chamber operates in the target operating state for a second preset period of time; a second control unit, for controlling the inner display panel to communicate with the main board again when the real-time temperature obtained again is closer to the preset temperature range than the real-time temperature obtained previously, and sending an instruction to the main board again through the inner display panel to continue controlling the target operating state of the variable temperature chamber to operate so that the real-time temperature of the variable temperature chamber falls within the preset range.

[0079] In an optional implementation manner of the embodiment of the present application, the device in the embodiment of the present application also includes: a second processing module, which is used to control the internal display panel to communicate with the main board again when the real-time temperature obtained again is far away from the preset temperature range compared to the real-time temperature obtained previously, and send a fault prompt to the main board through the internal display panel, and display the fault prompt on the external display panel of the refrigerator.

[0080] In an optional implementation manner of an embodiment of the present application, the first processing module in the embodiment of the present application includes: a second control unit, which is used to control the target operating state of the variable temperature chamber and disconnect the communication between the inner display panel and the main board after the inner display panel sends an instruction to the main board; a second acquisition unit, which is used to obtain the rate of change of the real-time temperature of the variable temperature chamber within the second preset time period again after the variable temperature chamber runs in the target operating state for the second preset time period; a third control unit, which is used to control the inner display panel to communicate with the main board again when the rate of change is greater than the first preset threshold and less than the second preset threshold, and the real-time temperature of the variable temperature chamber is close to the preset temperature range, and send instructions to the main board again through the inner display panel to continue controlling the target operating state of the variable temperature chamber so that the real-time temperature of the variable temperature chamber falls within the preset range.

[0081] In an optional implementation manner of the embodiment of the present application, the device in the embodiment of the present application also includes: a third processing module, which is used to control the internal display panel to communicate with the main board again when the change rate is less than or equal to a preset threshold, or the change rate is greater than or equal to a second preset threshold, and send a fault prompt to the main board through the internal display panel, and display the fault prompt on the external display panel of the refrigerator.

[0082] In an optional implementation manner of the embodiment of the present application, the device in the embodiment of the present application also includes: a fourth processing module, which is used to control the main board to obtain the control parameters of the internal display panel currently controlling the temperature changing chamber when it is detected that the refrigerator door is closed; and a fifth processing module, which is used to control the main board to disconnect communication with the internal display panel after the control parameters are obtained.
