Description

Technical Field

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

[0002] Modified atmosphere storage technology can adjust the ambient atmosphere to extend the shelf life of food. It can be applied to refrigerators, which are equipped with a modified atmosphere module connected to the refrigerator's storage space. The modified atmosphere module uses electrochemical methods or chemical reactions to adjust the concentration of specific gases in the storage space, creating a suitable gas environment that can improve the refrigerator's preservation effect.

[0003] In the past, specific gas concentrations were detected and the operation of the modified atmosphere module was controlled based on these concentrations. However, the modified atmosphere module generates heat during operation, which causes the temperature of the storage space to drop slowly or even rise. Temperature is one of the important factors affecting the preservation quality of food, which is ultimately detrimental to food preservation. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a refrigerator control method, a refrigerator, a control device, and a storage medium, providing suitable preservation conditions in terms of temperature and specific gas concentration, and creating a good storage environment.

[0005] According to a first aspect of the present invention, a refrigerator control method is provided in the refrigerator, wherein the refrigerator is provided with a storage space and a controlled atmosphere module, the controlled atmosphere module being connected to the storage space, characterized in that the control method includes: acquiring a temperature detection value of the storage space and a gas concentration detection value of the storage space; when the temperature detection value is higher than or equal to a temperature threshold, prohibiting the controlled atmosphere module from starting; and when the temperature detection value is lower than the temperature threshold and the gas concentration detection value is higher than the gas concentration threshold, controlling the controlled atmosphere module to start.

[0006] The refrigerator control method according to embodiments of the present invention has at least the following beneficial effects:

[0007] The refrigerator control method of this invention detects the temperature and concentration of a specific gas in the storage space inside the refrigerator. When the detected temperature value is higher than or equal to a temperature threshold, the controlled atmosphere module is prohibited from starting. The controlled atmosphere module is only started when the detected temperature value is lower than the temperature threshold and the detected gas concentration value is higher than the gas concentration threshold. Since the concentration of the specific gas should not be too low for suitable preservation conditions, the controlled atmosphere module is only required to work when the concentration of the specific gas is higher than the gas concentration threshold, thereby reducing the working time of the controlled atmosphere module and reducing the duration of temperature fluctuations, while also saving energy. The controlled atmosphere module only operates after the detected temperature value is lower than the temperature threshold. Even if the controlled atmosphere module generates heat during operation, the temperature in the storage space can remain at a relatively low temperature, which is unlikely to affect the preservation effect. This design provides suitable preservation conditions in terms of temperature and specific gas concentration, creating a good storage environment.

[0008] According to some embodiments of the present invention, the refrigerator control method further includes: controlling the controlled atmosphere module to stop when the temperature detection value is higher than or equal to a temperature threshold.

[0009] According to some embodiments of the present invention, the refrigerator control method further includes: controlling the modified atmosphere module to stop when the gas concentration detection value is lower than or equal to the gas concentration threshold.

[0010] According to some embodiments of the present invention, the refrigerator control method further includes: recording the running time of the controlled atmosphere module; and controlling the controlled atmosphere module to stop when the running time reaches a running time threshold.

[0011] According to some embodiments of the present invention, the refrigerator control method further includes: acquiring a humidity detection value of the storage space; allowing the controlled atmosphere module to start when the humidity detection value is lower than a humidity threshold; and controlling the controlled atmosphere module to stop when the humidity detection value is higher than or equal to the humidity threshold.

[0012] According to some embodiments of the present invention, the temperature threshold is 5°C.

[0013] According to some embodiments of the present invention, the gas concentration threshold is an oxygen concentration threshold, and the oxygen concentration threshold is 5%.

[0014] According to a second aspect of the present invention, a refrigerator includes a cabinet with a storage space, a controlled atmosphere module, and a control module. The controlled atmosphere module is disposed in the cabinet and communicates with the storage space. The control module is electrically connected to the controlled atmosphere module to control the controlled atmosphere module to implement the refrigerator control method disclosed in any of the above embodiments.

[0015] The refrigerator according to an embodiment of the present invention has at least the following beneficial effects:

[0016] The refrigerator of this invention has a storage space for storing food. The control module acquires the temperature detection value and the specific gas concentration detection value of the storage space. When the temperature detection value is higher than or equal to the temperature threshold, the controlled atmosphere module is prohibited from starting. Only when the temperature detection value is lower than the temperature threshold and the gas concentration detection value is higher than the gas concentration threshold, the controlled atmosphere module is controlled to start. Reasonable control can reduce the working time of the controlled atmosphere module, thereby reducing the duration of temperature fluctuations and saving energy. Furthermore, even if the controlled atmosphere module generates heat during operation, the temperature in the storage space can remain at a relatively low temperature, which is less likely to affect the preservation effect, thus creating a good preservation environment for the storage space.

[0017] According to some embodiments of the present invention, the modified atmosphere module includes a base shell, a cathode venting component, and an anode component. The base shell has a cavity for filling with electrolyte. The cathode venting component is disposed in the base shell, and the venting side of the cathode venting component corresponds to the storage space. The reaction side of the cathode venting component is in contact with the electrolyte. The anode component is disposed in the base shell and is in contact with the electrolyte.

[0018] According to some embodiments of the present invention, the cathode venting assembly includes a first venting membrane, a current collector layer, a second venting membrane, and a catalyst layer, all disposed on a substrate and stacked in sequence, wherein the first venting membrane corresponds to the storage space and the catalyst layer is in contact with the electrolyte.

[0019] A control device according to a third aspect of the present invention includes: one or more memories; one or more processors for executing one or more computer programs stored in the one or more memories, and for executing the refrigerator control method disclosed in any of the above embodiments.

[0020] A computer-readable storage medium according to a fourth aspect of the present invention includes instructions that, when executed on a computer, cause the computer to perform the refrigerator control method disclosed in any of the above embodiments.

[0032] The system includes a housing 100, a storage space 110, a refrigeration module 200, a control module 300, a controlled atmosphere module 400, a base shell 410, a cavity 411, a cathode venting assembly 420, a first venting membrane 421, a current collector layer 422, a second venting membrane 423, a catalyst layer 424, an anode assembly 430, an electrolyte 440, a temperature detection component 500, a gas concentration detection component 600, a memory 700, and a processor 800. Detailed Implementation

[0033] 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.

[0034] 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.

[0035] like Figure 1 As shown, Figure 1This is a schematic diagram of the principle structure of a refrigerator. The refrigerator generally includes a cabinet 100, a refrigeration module 200, a control module 300, a controlled atmosphere module 400, a temperature detection component 500, and a gas concentration detection component 600. A storage space 110 is provided within the cabinet 100. The cabinet 100 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 refrigeration module 200 is located within the cabinet 100, and its refrigeration section is connected to the storage space 110. The refrigeration module 200 can cool the internal environment of the storage space 110. Both the temperature detection component 500 and the gas concentration detection component 600 can be located within the storage space 110. The temperature detection component 500 is used to detect the real-time temperature in the storage space 110 to form a temperature detection value. The gas concentration detection component 600 is used to detect the concentration of certain specific gases in the storage space 110 to form a gas concentration detection value. Specifically, the temperature detection component 500 can be selected from commonly used temperature sensors. For the detection of different specific gas concentrations, different gas concentration detection components 600 can be set according to actual needs. If it is necessary to detect multiple specific gas concentrations, multiple different types of gas concentration detection components 600 can also be set. For example, it can detect gases such as oxygen, carbon dioxide, and ethylene. Correspondingly, the modified atmosphere module 400 can have multiple types to regulate gases such as oxygen, carbon dioxide, and ethylene.

[0036] The temperature detection value generated by the temperature detection component 500 can be output to the control module 300 for feedback control of the refrigeration module 200 to reasonably adjust the temperature of the internal environment of the storage space 110. The controlled atmosphere module 400 can be set on the cabinet 100 and located outside the storage space 110, and then connected to the storage space 110 through a pipe. Alternatively, the controlled atmosphere module 400 can also be set inside the storage space 110 of the cabinet 100.

[0037] like Figure 2 As shown, Figure 2 A refrigerator control method according to a first aspect embodiment of the present invention includes:

[0038] S11. Obtain the temperature detection value and the gas concentration detection value of the storage space; compare the temperature detection value with the temperature threshold, and compare the gas concentration detection value with the gas concentration threshold. The temperature threshold can be set by the user or the manufacturer according to the actual situation, while the gas concentration detection value is for different types of gases and can also be set by the user or the manufacturer according to the actual situation.

[0039] S12. When the temperature detection value is higher than or equal to the temperature threshold, the modified atmosphere module is prohibited from starting. When the temperature detection value is lower than the temperature threshold and the gas concentration detection value is higher than the gas concentration threshold, the modified atmosphere module is controlled to start.

[0040] It should be noted that there are many factors affecting the preservation quality of food placed in storage space. Among them, the temperature and specific gas concentration in the storage space are factors. Therefore, it is necessary to provide a comprehensive environment for food in the storage space. For example, in some cases, a relatively suitable food storage environment is a temperature of 3℃-6℃ and a relative humidity greater than 90%. Taking oxygen as an example, the oxygen concentration is 3%-7%. Therefore, in some embodiments of the present invention, the temperature threshold can be between 3℃ and 6℃. Specifically, the temperature threshold can be set to 5℃. Taking oxygen as an example, the gas concentration threshold can be the oxygen concentration threshold, which can be between 3% and 7%. Specifically, the oxygen concentration threshold can be set to 5%, but the above values ​​are not limited.

[0041] It should also be noted that the concentration of certain gases should not be too high, but it should not be too low either. Taking oxygen as an example, this is because if the oxygen concentration is too low, it will cause anaerobic respiration in fruits, vegetables and other food products, which is also not conducive to preservation.

[0042] The refrigerator control method of this invention detects the temperature and concentration of a specific gas in the storage space inside the refrigerator. When the detected temperature value is higher than or equal to a temperature threshold, the controlled atmosphere module is prohibited from starting. The controlled atmosphere module is only activated when the detected temperature value is lower than the temperature threshold and the detected gas concentration value is higher than the gas concentration threshold. Since suitable preservation conditions require that the concentration of the specific gas not be too low, the controlled atmosphere module only needs to operate when the concentration of the specific gas is higher than the gas concentration threshold. This reduces the operating time of the controlled atmosphere module, thereby reducing the duration of temperature fluctuations and saving energy. The controlled atmosphere module only operates after the detected temperature value is lower than the temperature threshold. Even if the controlled atmosphere module generates heat during operation, the temperature in the storage space remains relatively stable. The temperature can also be kept at a relatively low level, which is not likely to affect the preservation effect. Moreover, when preserving fruits and vegetables, temperature often has a greater impact on the quality of the fruits and vegetables than gas concentration. The control logic of this design allows the controlled atmosphere module to start operating only when the temperature is below the temperature threshold. In addition, when the user puts in the food, the door panel is opened and closed, which connects the storage space with the external environment and causes the temperature of the storage space to rise. This requires the cooling module to work to cool the storage space quickly. The control logic of this design can control the controlled atmosphere module to start operating only after the temperature of the storage space drops below the temperature threshold, which can prevent the temperature drop rate from slowing down after the controlled atmosphere module is started.

[0043] This design provides suitable temperature and specific gas concentrations for preservation, creating a good storage environment. 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.

[0044] In some embodiments of the present invention, such as Figure 3 As shown, the refrigerator control method also includes:

[0045] S13. When the temperature detection value is higher than or equal to the temperature threshold, control the modified atmosphere module to stop.

[0046] During the operation of the modified atmosphere module, if the operation of the modified atmosphere module causes the temperature of the storage space to rise, and the temperature detection value is higher than or equal to the temperature threshold, timely control of the modified atmosphere module to stop can prevent the temperature in the storage space from continuing to rise, thereby affecting the preservation of food.

[0047] As mentioned above, the concentration of certain gases should not be too high, but it should also not be too low. Too low a concentration of a particular gas can also affect the preservation of food. Therefore, in some embodiments of the present invention, such as... Figure 4 As shown, the refrigerator control method also includes:

[0048] S14. When the gas concentration detection value is lower than or equal to the gas concentration threshold, control the modified atmosphere module to stop.

[0049] When a user opens or closes the door to place food into the storage space, the temperature and concentration of a specific gas inside the storage space are generally at a high level. Once the temperature inside the storage space drops to the temperature threshold, the modified atmosphere module can be triggered to start operating. When the gas concentration detection value is lower than or equal to the gas concentration threshold, the preservation conditions of the specific gas concentration in the storage space are at an optimal level, and the modified atmosphere module can be stopped in time to prevent the concentration of the specific gas from continuing to decrease.

[0050] In some embodiments of the present invention, for controlling the start and stop of the controlled atmosphere module so that the concentration of a specific gas in the storage space is neither too high nor too low, the refrigerator control method may also adopt the following embodiments, including: recording the running time of the controlled atmosphere module; when the running time reaches the running time threshold, controlling the controlled atmosphere module to stop.

[0051] It should be noted that, within a given storage space, for a certain specification of modified atmosphere module, the manufacturer can know the modified atmosphere efficiency of the module. During the operation of the modified atmosphere module, by recording the operating time of the modified atmosphere module, the amount of specific gas eliminated by the modified atmosphere module after the modified atmosphere treatment in the storage space can be basically estimated, thereby calculating the degree of decrease in the concentration of specific gas in the storage space.

[0052] Taking the modified atmosphere module as an example of an oxygen regulating module, 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 such as the operating time threshold for judgment based on this situation, thereby controlling 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.

[0053] Specifically, after the user opens the door and places the food into the storage space, since the storage space is connected to the external environment, the concentration of a specific gas in the storage space rises to a level that is basically the same as that in the external environment. Taking oxygen as an example, when the user opens the door, oxygen from the external environment will quickly enter the storage space, making the oxygen concentration in the storage space basically the same as the oxygen concentration in the external environment. Therefore, based on the deoxygenation efficiency of a certain specification of oxygen regulation module, it is possible to determine how long the oxygen regulation module needs to run to reach the target range of oxygen concentration for preservation in the storage space, thereby specifying the operating time threshold.

[0054] In this embodiment, without the need to detect the concentration of a specific gas, the control logic can be specified using a time threshold parameter to stop the controlled atmosphere module, thereby reducing the actual concentration of the specific gas to a suitable range for preservation.

[0055] In some embodiments of the present invention, such as Figure 5 As shown, the refrigerator control method also includes:

[0056] S21. Obtain the humidity detection value of the storage space and compare the humidity detection value with the humidity threshold. The humidity threshold can be set by the user or the manufacturer according to the actual situation. For example, the humidity threshold can be set to 95%. There is no specific limitation here.

[0057] S22. When the humidity detection value is lower than the humidity threshold, the controlled atmosphere module is allowed to start.

[0058] S23. When the humidity detection value is higher than or equal to the humidity threshold, control the modified atmosphere module to stop.

[0059] It should be noted that for certain types of modified atmosphere modules, such as those that achieve modified atmosphere by reacting electrodes and electrolyte with specific gases, water molecules from the electrolyte may enter the storage space during operation, causing the humidity of the storage space to rise. This can easily lead to condensation on the surface of objects. Therefore, the humidity in the storage space should not be too high.

[0060] By combining humidity conditions with temperature and specific gas concentration conditions, the modified atmosphere module can be activated when the humidity detection value is below the humidity threshold, the temperature detection value is below the temperature threshold, and the gas concentration detection value is above the gas concentration threshold. During the operation of the modified atmosphere module, when the humidity detection value is above or equal to the humidity threshold, the modified atmosphere module can be stopped in time to avoid condensation on the surface of the object, which would affect the preservation effect.

[0061] A refrigerator according to a second aspect embodiment of the present invention, such as Figure 1 As shown, the refrigerator includes a cabinet 100 with a storage space 110, a controlled atmosphere module 400, and a control module 300. The controlled atmosphere module 400 is disposed in the cabinet 100 and communicates with the storage space 110. The control module 300 is electrically connected to the controlled atmosphere module 400 to control the controlled atmosphere module 400 to implement the refrigerator control method disclosed in any of the above embodiments.

[0062] In this embodiment of the refrigerator, the storage space 110 can be used to store food. The control module 300 acquires the temperature detection value and the specific gas concentration detection value of the storage space 110. When the temperature detection value is higher than or equal to the temperature threshold, the controlled atmosphere module 400 is prohibited from starting. Only when the temperature detection value is lower than the temperature threshold and the gas concentration detection value is higher than the gas concentration threshold, the controlled atmosphere module 400 is controlled to start. Reasonable control can reduce the working time of the controlled atmosphere module 400, thereby reducing the duration of temperature fluctuations and saving energy. Furthermore, even if the controlled atmosphere module 400 generates heat during operation, the temperature inside the storage space 110 can remain at a relatively low temperature, which is less likely to affect the preservation effect, thus creating a good preservation environment for the storage space 110.

[0063] In some embodiments of the present invention, the modified atmosphere module 400 may employ components that perform electrochemical methods or components that perform chemical reactions, for example, Figure 6 As shown, the modified atmosphere module 400 includes a base shell 410, a cathode venting component 420, and an anode component 430. The base shell 410 has a cavity 411 for filling electrolyte 440. The cathode venting component 420 is disposed in the base shell 410, and the venting side of the cathode venting component 420 corresponds to the storage space 110. The reaction side of the cathode venting component 420 is in contact with the electrolyte 440. The anode component 430 is disposed in the base shell 410 and is in contact with the electrolyte 440.

[0064] Taking oxygen as an example, the oxygen regulating module can adopt the above structure. The control module 300 supplies power to the anode component 430 and the cathode venting component 420 to enable the modified atmosphere module 400 to start and run. The oxygen in the storage space 110 can enter the cavity 411 filled with electrolyte 440 through the cathode venting component 420. The oxygen and electrolyte 440 undergo electrochemical reduction to produce OH- and / or HO2. The OH- and / or HO2 then diffuse from the electrolyte 440 to the anode component 430 to undergo an oxidation reaction to form oxygen and be discharged. This modified atmosphere module 400 structure makes the control accurate and the operation convenient.

[0065] In some embodiments of the present invention, the oxygen regulating module can also use chemical deoxygenating materials such as CaO and Fe for deoxygenation. The chemical deoxygenating material is placed inside the housing, and the housing is provided with a baffle that can open or close the inside of the housing. The control module 300 can electrically control the action of the baffle to make the chemical deoxygenating material come into contact with the gas in the storage space 110 to achieve the purpose of deoxygenation.

[0066] In embodiments where the modified atmosphere module 400 includes a cathode venting assembly 420, such as Figure 7 As shown, the cathode venting assembly 420 includes a first venting membrane 421, a current collector layer 422, a second venting membrane 423, and a catalyst layer 424, all of which are stacked sequentially on the base shell 410. The first venting membrane 421 corresponds to the storage space 110, and the catalyst layer 424 is in contact with the electrolyte 440.

[0067] Specifically, both the first breathable membrane 421 and the second breathable membrane 423 can be made of polytetrafluoroethylene (PTFE) as waterproof and breathable membranes, allowing gas to pass through while preventing the electrolyte 440 from flowing into the storage space 110. The current collector layer 422 can be a nickel mesh or a copper mesh. The control module 300 can supply power to the current collector layer 422. The catalyst layer 424 can be activated carbon and PTFE (polytetrafluoroethylene), etc. The cathode venting component 420 can allow specific gases such as oxygen to pass through and catalyze the reduction reaction between oxygen and electrolyte 440, resulting in high oxygen removal efficiency.

[0068] Control device according to a third aspect embodiment of the present invention, such as Figure 8 As shown, it includes: one or more memories 700; one or more processors 800, for executing one or more computer programs stored in one or more memories 700, and also for executing the control method of the controlled atmosphere module 400 disclosed in any of the above embodiments.

[0069] It should be noted that the specific implementation process of this embodiment can be found in the specific implementation process of the above method embodiments, and will not be described again here.

[0071] It should be noted that the specific implementation process of this embodiment can be found in the specific implementation process of the above method embodiments, and will not be described again here.

The program can be stored in a computer-readable storage medium, including read-only memory (ROM), random access memory (RAM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), one-time programmable read-only memory (OTPROM), electrically-erasable programmable read-only memory (EEPROM), compactdisc read-only memory (CD-ROM) or other optical disc storage, disk storage, magnetic tape storage, or any other computer-readable medium capable of carrying or storing data.
