Description

Technical Field

[0001] This invention relates to the field of modified atmosphere storage technology, and in particular to a control method for a refrigerator, as well as the refrigerator, control device, and storage medium. Background Technology

[0002] Modified atmosphere storage technology can adjust the ambient atmosphere to extend the shelf life of food. This technology can be applied to refrigerators by installing a modified atmosphere module that is connected to the refrigerator's storage space. By using electrochemical methods and chemical reactions to adjust the concentration of specific gases in the storage space, a suitable gas environment can be created, which can improve the refrigerator's preservation effect.

[0003] Modified atmosphere modules consume energy and generate heat during operation, which can raise the temperature of the storage space and affect the preservation of food. Furthermore, there is a relatively optimal range of gas concentrations for food preservation; the concentration of a specific gas cannot be too high or too low. Therefore, traditional refrigerators are equipped with gas concentration sensors to detect the concentration of specific gases in the refrigerator's storage space and provide feedback control for the operation of the modified atmosphere module. However, the above structure requires the addition of auxiliary circuits such as gas concentration sensors in the refrigerator, which increases the production cost. Summary of the Invention

[0013] According to some embodiments of the present invention, the refrigerator door panel can open or close the storage space, and the control method further includes: when a door switch trigger signal is detected, controlling the controlled atmosphere module to start operation according to the first controlled atmosphere mode; wherein, the door switch trigger signal is used to indicate that the refrigerator door panel changes from an open state to a closed state.

[0014] According to some embodiments of the present invention, the control method includes a second modified atmosphere mode, the second modified atmosphere mode including a second modified atmosphere step: controlling the modified atmosphere module to start running, if the temperature detection value reaches the upper temperature threshold, triggering the modified atmosphere module to stop, and controlling the modified atmosphere module to start running after a second stop time, accumulating the second running time of the modified atmosphere module, and triggering the modified atmosphere module to stop when the second running time reaches the second running time threshold.

[0015] According to some embodiments of the present invention, in the second modified atmosphere mode, the second modified atmosphere step is performed cyclically, with a third stop time between two adjacent second modified atmosphere steps, and the total stop time of the modified atmosphere module in the second modified atmosphere step is accumulated, and the third stop time is corrected according to the total stop time.

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number, while "above," "below," "within," "reaching," etc. are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0036] like Figure 1 As shown, Figure 1 This is a schematic diagram of the principle structure of a refrigerator. A typical refrigerator 100 includes a cabinet, a controlled atmosphere module 500, a temperature detection component 300, a refrigeration module, and a control module 400. The cabinet contains a storage space 110. Specifically, the cabinet also has a movable door panel, which can be moved to open or close the storage space 110. Users can place food in the storage space 110 for preservation. The controlled atmosphere module 500 can be mounted on the cabinet and located outside the storage space 110, and then connected to the storage space 110 via pipes. Alternatively, the controlled atmosphere module 500 can also... The temperature detection component 300 is installed in the storage space 110 of the enclosure. It can be selected from commonly used temperature sensors. The temperature detection component 300 is installed in the storage space 110 and can detect the real-time temperature in the storage space 110 to form a temperature detection value. The cooling module is installed in the enclosure and the cooling part of the cooling module is connected to the storage space 110. The cooling module can cool the internal environment of the storage space 110. The temperature detection value formed by the temperature detection component 300 can be used to feedback control the cooling module and reasonably adjust the temperature of the internal environment of the storage space 110.

[0037] like Figure 2 As shown, Figure 2 This is a flowchart of a refrigerator control method, the control method including:

[0038] S11. Control the start of the modified atmosphere module and record the running time of the modified atmosphere module;

[0039] S12. Obtain the temperature detection value of the storage space inside the refrigerator, compare the temperature detection value with the preset upper temperature threshold, and compare the running time with the preset running time threshold. Here, the upper temperature threshold and the running time threshold can be set by the user or the manufacturer according to the actual situation.

[0040] S13. When the temperature detection value reaches the upper temperature threshold, or when the running time reaches the running time threshold, control the controlled atmosphere module to stop.

[0041] It should be noted that the modified atmosphere module can be an oxygen regulating module, a carbon dioxide regulating module, an ethylene regulating module, etc., capable of processing specific gases such as oxygen, carbon dioxide, and ethylene. The modified atmosphere module can be selected from conventional electrochemical modified atmosphere modules. Specifically, for example, an oxygen regulating module may include an electrolytic chamber, an anode, and a cathode. The electrolytic chamber can be filled with electrolyte, and a permeable membrane is installed on the wall of the electrolytic chamber. The anode and cathode are located within the electrolytic chamber, with the cathode positioned on the permeable membrane. The electrolytic chamber also has a connection to the external environment. The air vent allows the outer surface of the breathable membrane to contact the air inside the storage space, while the inner surface of the breathable membrane contacts the electrolyte. Oxygen in the air can pass through the breathable membrane and undergo an oxidation-reduction reaction with the anode and cathode in the electrolysis chamber, being displaced to the outside. This creates a nitrogen-rich and oxygen-poor environment in the refrigerator's storage space, which is beneficial for food preservation. A similar structure can be used for carbon dioxide regulating modules. Oxygen and carbon dioxide permeate through the breathable membrane relatively quickly, while nitrogen permeates relatively slowly. Therefore, the modified atmosphere module can be used to create a nitrogen-rich environment in the storage space.

[0042] During the operation of the controlled atmosphere module, heat is released. Even when the cooling module is working, the temperature inside the storage space will still rise slowly. When the controlled atmosphere module stops, the temperature inside the storage space will drop because the cooling module is still working.

[0043] For food preservation, it is necessary to provide a comprehensive environment for the food. Taking oxygen concentration regulation as an example, the control of the preservation environment not only requires the control and maintenance of temperature and humidity, but also the regulation of oxygen concentration. For example, in some cases, the relatively suitable food preservation environment is a temperature of 3℃-6℃, a relative humidity of more than 90%, and an oxygen concentration of 3%-7%. In some embodiments, the upper limit threshold of temperature can be set to 6℃, or other values ​​can be used, which are not limited here.

[0044] This environment can effectively inhibit the respiration of fruits and vegetables, reduce the consumption of organic matter, allow fruit and vegetable cells to breathe slowly, maintain cell vitality, preserve the excellent flavor and aroma of fruits and vegetables, effectively inhibit the growth and reproduction of aerobic and anaerobic bacteria, prevent microbial spoilage of fruits and vegetables, delay the ripening and aging process, and maintain the nutritional freshness of fruits and vegetables for a long time.

[0045] Within a given storage space, for a specific type of modified atmosphere module, the manufacturer can determine the modified atmosphere efficiency of the module. By recording the operating time of the modified atmosphere module during its operation, the manufacturer can roughly estimate the amount of specific gas eliminated by the module after modified atmosphere treatment in the storage space, thereby calculating the degree of decrease in the concentration of the specific gas in the storage space.

[0046] In some embodiments of the present invention, the control method further includes recording the stop time of the modified atmosphere module and comparing the stop time with a preset stop time threshold. The stop time threshold can be set by the user or the manufacturer according to the actual situation. When the stop time reaches the stop time threshold, the modified atmosphere module can be triggered to start.

[0047] After the modified atmosphere module has stopped operating for a period of time, the concentration of a specific gas may rise to a certain extent because the sealing capacity of the modified atmosphere module is not ideal. Therefore, the stopping time of the modified atmosphere module can be recorded, and the modified atmosphere module can be started at regular intervals to reduce the concentration of a specific gas in the storage space in a timely manner.

[0048] Similarly, for a specific type of modified atmosphere (MAP) module, the manufacturer can determine the rate of gas resurgence within the module's sealing atmosphere. Therefore, based on the recorded stopping time of the MAP module, the degree of resurgence of a specific gas concentration can be predicted. The manufacturer can customize appropriate time threshold parameters according to the MAP module's specifications and storage capacity to reasonably control the specific gas concentration range within the storage space.

[0049] Taking an oxygen regulating module as an example, for a 15L storage space, a certain specification of oxygen regulating module has an oxygen removal efficiency of 4% / h and a sealed oxygen recovery rate of 0.6% / h. Users or manufacturers can formulate time threshold parameters for judgment based on this situation to control the oxygen concentration range. If other specifications of oxygen regulating modules are used, the preset time threshold parameters can be adjusted according to the actual situation without changing the logic of the control method in this design.

[0050] Based on the controlled atmosphere efficiency, operating time, and stopping time of the controlled atmosphere module, the amount of a specific gas eliminated or recovered within a certain time can be roughly determined, thereby predicting the concentration range of a specific gas in the storage space and optimizing the regulation and control of the concentration of a specific gas in the storage space.

[0051] The control method of this invention controls the operation of the modified atmosphere module, which can reduce the concentration of a specific gas in the storage space. The operation of the modified atmosphere module releases heat, and since the modified atmosphere module is connected to the storage space inside the refrigerator, this characteristic is cleverly utilized. By obtaining the temperature detection value in the storage space, the upper temperature threshold is used as the condition for stopping the modified atmosphere module, so that the temperature of the storage space will not be too high and affect the preservation effect. At the same time, by recording the running time, the modified atmosphere module is shut down in time after the running time threshold is reached. While prioritizing ensuring that the temperature of the storage space is within a suitable range, the concentration of a specific gas in the storage space is adjusted to provide suitable preservation conditions. There is no need to set up additional devices for gas concentration detection, thus reducing product production costs.

[0052] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the refrigerator 100 is also equipped with a door opening and closing detection component 200. The door opening and closing detection component 200 is located between the refrigerator body and the door panel. The door opening and closing detection component 200 can detect the opening and closing of the door panel. The control method may also include detecting a door opening and closing trigger signal fed back by the door opening and closing detection component. It should be noted that the door opening and closing trigger signal here refers to the signal generated by the door opening and closing detection component when it detects that the refrigerator door panel changes from the open state to the closed state. That is, the door opening and closing trigger signal is triggered once when the door panel changes from the open state to the closed state. In the control method, the controlled atmosphere module can be started and operated according to the door opening and closing trigger signal.

[0053] Taking oxygen as an example, since the external environment is rich in oxygen, when the user opens or closes the door, the storage space 110 is connected to the external environment. Oxygen from the external environment will quickly enter the storage space 110, causing the oxygen concentration in the storage space 110 to rise rapidly to a level basically the same as that in the outside. By using the opening and closing of the door as the trigger condition for controlling the start of the controlled atmosphere module 500, deoxygenation can be carried out in time after the oxygen concentration in the storage space 110 rises rapidly, thereby reducing the oxygen concentration in the storage space 110 and maintaining the freshness preservation ability of the storage space 110.

[0054] Specifically, the door opening / closing detection component 200 can be a micro switch, a photosensitive sensor, a magnetic sensor, etc. It should be noted that, depending on the specific implementation of the door opening / closing detection component 200, some door opening / closing detection components 200 will output a signal when the door panel is opened or closed. The door opening / closing trigger signal can be formed by processing the door opening signal or the door closing signal. For example, in the open state, the door opening / closing detection component 200 will feed back a high-level signal, while in the closed state, the port connected to the door opening / closing detection component 200 will change to a low level, thereby forming a door opening / closing trigger signal to determine whether the door panel has changed from the open state to the closed state.

[0055] Under normal circumstances, the temperature of the external environment is higher than the temperature inside the storage space 110. When the user opens or closes the door, connecting the storage space 110 to the external environment, it will also cause the temperature inside the storage space 110 to rise.

[0056] Therefore, in some embodiments of the present invention, such as Figure 3 As shown, the control method also includes:

[0057] S21. Obtain the door switch trigger signal;

[0058] S22. Compare the temperature detection value with the temperature trigger threshold. In S22, it is necessary to determine the temperature situation in the storage space and set the temperature trigger threshold in the control module. This temperature trigger threshold is lower than the upper temperature threshold.

[0059] S23. When the temperature detection value is equal to or lower than the temperature trigger threshold, the controlled atmosphere module can be triggered to start running.

[0060] In some embodiments, the temperature trigger threshold can be set to 5°C. When a door switch trigger signal is received and the temperature detection value of the storage space reaches 5°C under the operation of the refrigeration module, the controlled atmosphere module can be triggered to start operation. Under the condition that the temperature is not too high, the specific gas concentration in the storage space is reduced in time to maintain good preservation conditions. Furthermore, during the operation of the controlled atmosphere module, the condition judgment of the upper temperature threshold still needs to be followed.

[0061] In some embodiments of the present invention, time and temperature thresholds can be set as judgment conditions to form control logic to control the operation of the modified atmosphere module, thereby forming different modified atmosphere modes. For example, the control method of this design can set a first modified atmosphere mode, such as... Figure 4 As shown, the first modified atmosphere mode includes the first modified atmosphere step:

[0062] S31. Control the start of the controlled atmosphere module and keep it running continuously;

[0063] S32. Continue until the temperature detection value reaches the upper temperature threshold, triggering the controlled atmosphere module to stop.

[0064] In the first modified atmosphere mode, as long as the temperature detection value does not reach the upper temperature threshold, the modified atmosphere module can continue to operate, thereby reducing the concentration of a specific gas relatively quickly.

[0065] In some embodiments of the present invention, the first modified atmosphere mode can be further optimized, and the first modified atmosphere step may further include:

[0066] S33. Record the first running time of the modified atmosphere module. The first running time here can be understood as the time elapsed from the start of operation of the modified atmosphere module in the first modified atmosphere step until the modified atmosphere module stops due to the temperature detection value reaching the upper temperature threshold.

[0067] In the first modified atmosphere mode, the first modified atmosphere step is performed cyclically, with a first stop time interval between two adjacent first modified atmosphere steps. The first stop time threshold can be set. When the first stop time reaches the first stop time threshold, the modified atmosphere module is started. The first stop time threshold can be determined according to the actual situation, for example, it can be 30 minutes, but it is not specifically limited here.

[0068] During the first stop time, the controlled atmosphere module stops operating, while the cooling module operates to lower the temperature within the storage space, thus preparing the conditions for the next start-up of the controlled atmosphere module. After the first stop time, the first controlled atmosphere step is performed again, and the first running time of this first controlled atmosphere step is recorded, and the cycle is repeated.

[0069] Therefore, the first controlled atmosphere mode also includes:

[0070] S34. Accumulate the first running time of each first controlled atmosphere step in the cycle to obtain the total duration;

[0071] S35. Determine whether the total duration has reached the first running time threshold. If the total duration has not reached the first running time threshold, proceed to S36. If the total duration has reached the first running time threshold, proceed to S37. The first running time threshold can be set according to the actual situation. It can be set to 6h, 5.5h or other values. There is no specific limitation here.

[0072] S36. Start the modified atmosphere module after the first stop time;

[0073] S37, End the loop.

[0074] Therefore, in the first modified atmosphere mode, the modified atmosphere module continues to run as long as the temperature detection value does not reach the upper temperature threshold. This is equivalent to not setting a time threshold to trigger the modified atmosphere module to stop or setting the time threshold to trigger the modified atmosphere module to stop to be long enough. The continuously running modified atmosphere module can quickly reduce the concentration of a specific gas in the storage space.

[0075] It is conceivable that, due to the opening and closing of the door, the concentration of a specific gas in the storage space rises rapidly. In some embodiments of the present invention, after receiving the door opening and closing trigger signal from the door opening and closing detection component, the modified atmosphere module can be controlled to start operation in the first modified atmosphere mode to reduce the concentration of the specific gas with a faster degassing efficiency.

[0076] It should be noted that users can know the degassing efficiency and other parameters of the controlled atmosphere module. The controlled atmosphere module has run for a total of the first operating time threshold in the first controlled atmosphere mode. The decrease in the concentration of a specific gas can be estimated based on the degassing efficiency of the controlled atmosphere module. Generally, after the door is opened or closed, the controlled atmosphere module is controlled to run in the first controlled atmosphere mode, and the concentration of the specific gas in the outside can also be roughly determined. After the door is opened, the concentration of the specific gas in the storage space will be basically the same as that in the outside. Therefore, by setting the first operating time threshold appropriately, the operating time of the first controlled atmosphere mode can be controlled. Based on the relationship between the degassing volume, the degassing efficiency of the controlled atmosphere module, and time, the range of the concentration of the specific gas in the storage space can be reasonably adjusted.

[0077] Specifically, such as Figure 6 As shown, the control logic can be set as follows: when a door switch trigger signal is received and the temperature detection value reaches the temperature trigger threshold, the controlled atmosphere module is controlled to enter the first controlled atmosphere mode. One embodiment of the first controlled atmosphere mode may include:

[0078] S41. The controlled atmosphere module starts running when the temperature detection value rises;

[0079] S42. Determine whether the temperature detection value has reached the upper temperature threshold.

[0080] If so, proceed to S43, control the modified atmosphere module to stop, and record the first running time Tn of the modified atmosphere module. When the first modified atmosphere step is performed for the first time, n=1. After the first stop time, control the modified atmosphere module to start running according to the first modified atmosphere step again. When the temperature detection value rises and reaches the upper temperature threshold, control the modified atmosphere module to stop and record the first running time Tn of the modified atmosphere module. When the first modified atmosphere step is performed for the second time, n=2, and so on.

[0081] S44, Total cumulative duration = T1 + T2 + ... + Tn;

[0082] S45. Determine whether the total duration is equal to or greater than the first running time threshold. If the total duration is equal to or greater than the first running time threshold, control the modified atmosphere module to exit the first modified atmosphere mode. If not, proceed to step S41 and continue the loop operation.

[0083] In some embodiments of the present invention, the control method of this design can be set to a second controlled atmosphere mode, such as... Figure 5 As shown, the second modified atmosphere mode includes a second modified atmosphere step:

[0084] S51. Control the controlled atmosphere module to start running, acquire temperature detection values ​​and make judgments using temperature detection values ​​and temperature upper limit thresholds;

[0085] S52. Determine whether the temperature detection value has reached the upper temperature threshold. If the temperature detection value has not reached the upper temperature threshold, control the controlled atmosphere module to continue running. If the temperature detection value has reached the upper temperature threshold, proceed to S53.

[0086] S53. Trigger the controlled atmosphere module to stop, and wait for the cooling module to work to gradually reduce the temperature of the storage space.

[0087] S54. Control the controlled atmosphere module to start operation after the second stop time;

[0088] S55, cumulative second running time of the modified atmosphere module;

[0089] S56. When the second running time reaches the second running time threshold, control the controlled atmosphere module to stop.

[0090] The second running time threshold can be set by the user according to the actual situation. For example, the second running time threshold is 30 minutes. It is not specifically limited here. It should be noted that the second running time threshold is relatively short. Under normal circumstances, the operation of the controlled atmosphere module in the second controlled atmosphere step will not cause the temperature detection value in the storage space to reach the upper temperature threshold. Therefore, the controlled atmosphere module will generally continue to run until the second running time reaches the second running time threshold, and then stop.

[0091] Therefore, compared to the first controlled atmosphere mode, in the second controlled atmosphere mode, the module continues to operate as long as the detected temperature value does not reach the upper temperature threshold. In the second controlled atmosphere mode, however, the second operating time needs to be compared with a second operating time threshold; if the second operating time reaches the threshold, the controlled atmosphere module will stop.

[0092] Over a longer period of time, the average degassing efficiency achieved by the modified atmosphere module operating in the first modified atmosphere mode is higher than that achieved by the modified atmosphere module operating in the second modified atmosphere mode. However, the energy consumption of the modified atmosphere module operating in the first modified atmosphere mode is also higher than that of the modified atmosphere module operating in the second modified atmosphere mode.

[0093] It is conceivable that, such as Figure 6 As shown, with the operation of the controlled atmosphere module, the energy consumption of the refrigerator and the temperature of the storage space will also increase accordingly. This design can control the controlled atmosphere module to switch between the first controlled atmosphere mode and the second controlled atmosphere mode according to the actual situation. For example, when the concentration of a specific gas in the storage space is high, the first controlled atmosphere mode can be used to quickly reduce the concentration of the specific gas, and then the second controlled atmosphere mode can be used to reduce energy consumption.

[0094] Under normal circumstances, after the door is opened or closed, the modified atmosphere module can be controlled to operate in the first modified atmosphere mode to quickly remove gas. When the door has not been opened or closed for a long time, the modified atmosphere module can be controlled to operate in the second modified atmosphere mode to reasonably control the concentration of specific gases and reduce energy consumption.

[0095] Specifically, the refrigerator can be equipped with control buttons, and the control module is connected to the control buttons. By operating the control buttons, the user inputs control signals to the control module, which then controls the controlled atmosphere module to operate in either the first or second controlled atmosphere mode, and can switch between the first and second controlled atmosphere modes.

[0096] In some embodiments of the present invention, switching logic conditions can also be set in the control module, and the control module can automatically control the modified atmosphere module to switch between the first modified atmosphere mode and the second modified atmosphere mode.

[0097] In addition, in the second modified atmosphere step, a second stop time threshold can be set. When the second stop time reaches the second stop time threshold, the modified atmosphere module is controlled to start. The second stop time threshold and the second running time threshold can be set by the user. For example, the second stop time threshold can be set to 30 minutes, and the second running time threshold can also be set to 30 minutes. There is no specific limitation here.

[0098] Since users can know parameters such as the degassing efficiency of the controlled atmosphere module, they can control the concentration of a specific gas within a suitable range by stopping the controlled atmosphere module according to the second operating time threshold.

[0099] In some embodiments of the present invention, in the second modified atmosphere mode, the second modified atmosphere step can be performed cyclically, and a third stop time is spaced between two adjacent second modified atmosphere steps, i.e., as shown below. Figure 6 As shown, the control method in the second controlled atmosphere mode also includes:

[0100] S57, after the third stop time, enter S51.

[0101] Furthermore, in some embodiments of the present invention, the total stop time of the modified atmosphere module during the second modified atmosphere step can be accumulated, and the third stop time can be corrected based on the total stop time.

[0102] After completing the second modified atmosphere step, the concentration of a specific gas in the storage space has dropped to a reasonable level, and the third stop time can be stopped to reduce energy consumption. However, during the second modified atmosphere step, the modified atmosphere module may stop because the temperature detection value reaches the upper temperature threshold. At this time, due to issues such as the sealing not being ideal, the specific gas may rebound to a certain extent. If the second stop time is ignored, it may lead to inaccurate prediction of the concentration of the specific gas in the future.

[0103] Therefore, the total stop time of the modified atmosphere module during the second modified atmosphere step can be accumulated, i.e., total stop time = second stop time * number of stops. It should be noted that a second stop time does not occur every time the second modified atmosphere step is performed. If the temperature detection value does not reach the upper temperature threshold during the entire second modified atmosphere step, then there is no second stop time for this second modified atmosphere step. Then, the third stop time is adjusted according to the total stop time. The third stop time can be set by the user, for example, the third stop time can be 3h, 3.3h, 5h, etc., without specific limitations. For example, the third stop time can be adjusted to the difference between the original third stop time and the total stop time. Assuming the third stop time is 3h, and the operation stops once in the second modified atmosphere step, the total stop time = the second stop time, i.e., 30min. Then, after the end of this second modified atmosphere step, there needs to be an interval of 2.5h before the next second modified atmosphere step starts the modified atmosphere module.

[0104] It is conceivable that other correction models can be used to correct the third stopping time. For example, the third stopping time can be corrected with a set correction ratio. For instance, the total stopping time can be divided into different time intervals based on its length, with each time interval corresponding to a different correction ratio. When the total stopping time matches one of the time intervals, the correction ratio matching that time interval is obtained, and the third stopping time is corrected to the original third stopping time * the correction ratio.

[0105] In some embodiments of the present invention, the control method of this design can be set to a third modified atmosphere mode. The third modified atmosphere mode can be used as another embodiment of the first modified atmosphere mode, and can also achieve the effect of rapid degassing. Specifically, when a door switch trigger signal is obtained and the temperature detection value reaches the temperature trigger threshold, the modified atmosphere module is controlled to enter the third modified atmosphere mode.

[0106] like Figure 7 As shown, the third modified atmosphere mode may include the third modified atmosphere step:

[0107] S61. Control the start-up and operation of the controlled atmosphere module;

[0108] S62. Determine whether the temperature detection value has reached the upper temperature threshold. If the temperature detection value has reached the upper temperature threshold;

[0109] S63, Trigger the controlled atmosphere module to stop;

[0110] S64. After the fourth stop time, control the controlled atmosphere module to start running again;

[0111] S65. Accumulate the third running time of the modified atmosphere module. When the third running time reaches the third running time threshold, the modified atmosphere module is triggered to stop.

[0112] In the third controlled atmosphere mode, the third controlled atmosphere step is repeated cyclically;

[0113] S66. The cumulative number of times the third modified atmosphere step is executed;

[0114] S67. Determine whether the number of executions has reached the total number of executions threshold. If the number of executions has reached the total number of executions threshold, end the loop. Otherwise, proceed to S68.

[0115] S68. After the fifth stop time, enter S61, which is equivalent to cyclically performing the third gas control step. The fifth stop time is between two adjacent third gas control steps.

[0116] Additionally, it should be noted that in the third controlled atmosphere step, if the temperature detection value in S62 does not reach the upper temperature threshold, then proceed to S65, where the controlled atmosphere module continues to run for the third running time. When the third running time reaches the third running time threshold, the controlled atmosphere module is triggered to stop, and then proceed to S66.

[0117] It is conceivable that the third running time threshold can be set by the user according to the actual situation, such as 30 minutes, without being specifically limited here.

[0118] After the modified atmosphere module stops at the fifth stop time, it is restarted to cycle through the third modified atmosphere steps until the total number of executions reaches the threshold. Then, the modified atmosphere module exits the third modified atmosphere mode. The fourth and fifth stop time thresholds can be set separately. The fourth stop time threshold is used to compare with the fourth stop time, and the fifth stop time threshold is used to compare with the fifth stop time threshold. The fourth stop time threshold, the fifth stop time threshold, and the total number of executions threshold can all be set by the user or the manufacturer. For example, the fourth stop time threshold can be set to 30 minutes, the fifth stop time threshold can be set to 30 minutes, and the total number of executions threshold can be set to 9 times. There are no specific limitations here.

[0119] In some embodiments of the present invention, such as Figure 6 , 7 As shown, after the control module controls the modified atmosphere module to exit the first or third modified atmosphere mode, it can perform S7 and switch to the second modified atmosphere mode after the sixth stop time. Similarly, a sixth stop time threshold can be set for comparison with the sixth stop time. The sixth stop time can be set by the user according to the actual situation, for example, the sixth stop time is 5h, which is not specifically limited here.

[0120] According to a second aspect embodiment of the refrigerator 100, such as Figure 1 As shown, the control module 400 is electrically connected to the modified atmosphere module 500 to control the modified atmosphere module 500 to implement the control method of the modified atmosphere module 500 disclosed in any of the above embodiments.

[0121] The refrigerator 100 of this invention has a storage space 110 for storing food. The control module 400 controls the controlled atmosphere module 500 connected to the storage space 110 to start operation. During operation, the controlled atmosphere module 500 releases heat to reduce the concentration of a specific gas in the storage space 110. This design cleverly utilizes this characteristic, eliminating the need for devices to detect gas concentration. By setting a threshold parameter for the upper limit of temperature as the condition for stopping the controlled atmosphere module 500, and by using a time parameter to regulate the reasonable operation of the controlled atmosphere module 500, the temperature and specific gas concentration of the storage space 110 can be kept within a suitable range, providing suitable preservation conditions and reducing the production cost of the refrigerator 100.
