[0002] As living standards improve, consumers have increasingly higher requirements for food preservation. The storage time of fruits and vegetables is affected by temperature, humidity, and the concentration of gas components.

[0003] However, in practical applications, when refrigerators use controlled atmosphere storage to preserve food, they also remove some water vapor along with oxygen or ethylene, thus lowering humidity. Currently, there is no solution for actively controlling humidity while using controlled atmosphere storage in a refrigerator. Summary of the Invention

[0004] This application provides a method, apparatus, device, and readable storage medium for controlling humidity in a refrigerator, so as to achieve the technical effect of actively regulating humidity while maintaining controlled atmosphere preservation.

[0005] In a first aspect, this application provides a method for controlling humidity in a refrigerator. The refrigerator has a fruit and vegetable compartment, which is equipped with a fan connecting the fruit and vegetable compartment to the outside. The method includes: detecting the gas concentration value in the fruit and vegetable compartment, which is the concentration value of oxygen and ethylene; if the gas concentration value is greater than a preset gas concentration value, controlling the fan to rotate in a first direction for a first duration to extract gas from the fruit and vegetable compartment; detecting the current humidity value in the fruit and vegetable compartment; if the current humidity value is less than a first preset humidity value, controlling the fan to rotate in a second direction for a second duration to deliver gas into the fruit and vegetable compartment, wherein the first direction is opposite to the second direction; when the current humidity value is greater than the first preset humidity value, controlling the fan to stop rotating and executing the humidity control method again; wherein the first duration is greater than the second duration so that the amount of gas extracted from the fruit and vegetable compartment is greater than the amount of gas entering the fruit and vegetable compartment.

[0006] In one possible implementation, the humidity control method of the refrigerator further includes: if the current humidity value is greater than a first preset humidity value, continuously controlling the fan to rotate in a first direction to extract gas from the fruit and vegetable compartment; when the gas concentration value is less than a preset gas concentration value, controlling the fan to stop rotating.

[0007] In one possible implementation, after controlling the fan to stop rotating when the gas concentration value is less than a preset gas concentration value, the method further includes: detecting the current humidity value in the fruit and vegetable compartment; if the current humidity value is greater than a second preset humidity value, controlling the fan to rotate in a first direction to extract gas from the fruit and vegetable compartment; and controlling the fan to stop rotating when the current humidity value is less than the second preset humidity value; wherein the second preset humidity value is greater than the first preset humidity value.

[0008] In one possible implementation, the humidity control method of the refrigerator further includes: if the gas concentration value is less than the preset gas concentration value, detecting and calculating the humidity value in the fruit and vegetable compartment to obtain the average humidity value; comparing the average humidity value with the first preset humidity value and the second preset humidity value; and controlling the fan to rotate in the first direction or the second direction according to the comparison result.

[0009] In one possible implementation, based on the comparison result, the fan is controlled to rotate in a first direction or a second direction. The humidity control method of the refrigerator also includes: if the average humidity is less than a first preset humidity value, the fan is controlled to rotate in a second direction to deliver gas into the fruit and vegetable compartment.

[0010] In one possible implementation, the refrigerator's humidity control method further includes: detecting the current humidity value inside the fruit and vegetable compartment; when the current humidity value is greater than a second preset humidity value, controlling the fan to stop rotating, and executing the humidity control method again.

[0011] In one possible implementation, based on the comparison result, the fan is controlled to rotate in a first direction or a second direction. The humidity control method of the refrigerator also includes: if the average humidity is greater than a second preset humidity value, the fan is controlled to rotate in the first direction to extract the gas in the fruit and vegetable compartment.

[0012] In one possible implementation, the humidity control method of the refrigerator further includes: detecting the current humidity value in the fruit and vegetable compartment; if the humidity value is less than a third preset humidity value, controlling the fan to stop rotating; wherein the third preset humidity value is less than the second preset humidity value and greater than the first preset humidity value.

[0013] Secondly, this application provides a humidity control device. The refrigerator has a fruit and vegetable compartment, which is equipped with a fan that connects the fruit and vegetable compartment to the outside. The humidity control device includes: a detection module configured to detect the gas concentration value in the fruit and vegetable compartment and the current humidity value in the fruit and vegetable compartment; and a control module configured to control the fan to rotate in a first direction for a first time, control the fan to rotate in a second direction for a second time, and control the fan to stop rotating.

[0014] Thirdly, this application provides a humidity control device, including: a memory storing computer program instructions; and a processor that implements a humidity control method for a refrigerator when the computer program instructions are executed by the processor.

[0015] Fourthly, this application provides a computer-readable storage medium including instructions that, when executed on a computer, cause the computer to perform a humidity control method for a refrigerator.

[0016] Compared with the prior art, the technical solution provided in this application has the following advantages: The refrigerator is equipped with a dedicated fruit and vegetable compartment. A fan is installed on the side wall of the fruit and vegetable compartment, and the fan can rotate along a first direction and a second direction, which are opposite to each other. When the fan rotates along the first direction, it draws the gas out of the fruit and vegetable compartment, reducing the oxygen or ethylene content and slowing down the oxidation of the fruits and vegetables. When the fan rotates along the second direction, it sends high-humidity gas from outside into the fruit and vegetable compartment, increasing the humidity inside.

[0017] First, the gas concentration inside the fruit and vegetable compartment is detected, primarily the oxygen or ethylene concentration. When the concentration of either of these gases is too high, the fan is controlled to rotate in the first direction to extract air. After the fan has been running for a certain period, the humidity inside the fruit and vegetable compartment is detected and compared with a preset humidity value. If the current humidity value is lower than the first preset humidity value, the fan is controlled to reverse, rotating in the second direction to bring in high-humidity air from outside. When the detected current humidity value is higher than the first preset humidity value, the fan is controlled to stop rotating. During fan operation, the first rotation time in the first direction and the second rotation time in the second direction are adjusted, ensuring that the first rotation time is greater than the second rotation time. This ensures that the amount of air extracted is always greater than the amount of air entering, keeping the oxygen or ethylene levels inside the refrigerator decreasing and the humidity inside the fruit and vegetable compartment increasing, thus achieving controlled atmosphere and humidity control within the compartment.

[0018] By controlling the forward and reverse rotation of the fan in the fruit and vegetable compartment, controlled atmosphere and humidity can be achieved. By ensuring that the amount of gas discharged from the fruit and vegetable compartment is less than the amount of gas entering the compartment, the humidity inside the refrigerator can be maintained while controlling the gas concentration. This controlled atmosphere and humidity control preserves food. Compared with other controlled atmosphere refrigerators, the method proposed in this proposal can control humidity to achieve better preservation results. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0029] In order to solve the technical problem that the humidity will decrease when the refrigerator is used for air extraction preservation, this application provides a method, device, equipment and readable storage medium for controlling humidity in a refrigerator, so as to achieve the technical effect of actively adjusting humidity while the refrigerator is used for controlled atmosphere preservation.

[0030] In some embodiments, Figure 1 This is a flowchart illustrating a humidity control method for a refrigerator. The solution provides a humidity control method for a refrigerator, which includes a fruit and vegetable compartment equipped with a fan connecting the compartment to the outside. The method includes:

[0031] Step S100: Detect the gas concentration values ​​in the fruit and vegetable compartment. The gas concentration values ​​are the oxygen concentration value and the ethylene concentration value.

[0032] Step S111: If the gas concentration value is greater than the preset gas concentration value, control the fan to rotate in the first direction for a first duration to extract the gas in the fruit and vegetable compartment.

[0033] Step S112: Detect the current humidity level inside the fruit and vegetable compartment;

[0034] Step S113: If the current humidity value is less than the first preset humidity value, control the fan to rotate in the second direction for a second duration to deliver gas into the fruit and vegetable chamber. The first direction is opposite to the second direction.

[0035] Step S114: When the current humidity value is greater than the first preset humidity value, control the fan to stop rotating and execute the humidity control method again;

[0036] The first duration is longer than the second duration so that the amount of gas extracted from the fruit and vegetable compartment is greater than the amount of gas entering the fruit and vegetable compartment.

[0037] For details, see Figure 2 The refrigerator has a dedicated fruit and vegetable compartment. A fan is installed on the side wall of this compartment, and the fan can rotate in two opposing directions. When the fan rotates in the first direction, it draws air out of the compartment, reducing oxygen and ethylene levels and slowing down the oxidation of the fruits and vegetables. When the fan rotates in the second direction, it introduces humid air from outside into the compartment, increasing the humidity level.

[0038] The main gases affecting food freshness are oxygen and ethylene. High oxygen levels in the fruit and vegetable compartment accelerate oxidation and spoilage, shortening shelf life. Additionally, food releases ethylene into the compartment, which has a ripening effect; excessively high ethylene levels also shorten shelf life. Therefore, when testing the gas concentration in the fruit and vegetable compartment, oxygen concentration is the primary focus; however, testing only the oxygen concentration is also acceptable.

[0039] First, the gas concentration inside the fruit and vegetable compartment is detected, primarily the oxygen or ethylene concentration. When the concentration of either of these gases is too high, the fan is controlled to rotate in the first direction to extract air. After the fan has been running for a certain period, the humidity inside the fruit and vegetable compartment is detected and compared with a preset humidity value. If the current humidity value is lower than the first preset humidity value, the fan is controlled to reverse, rotating in the second direction to bring in high-humidity air from outside. When the detected current humidity value is higher than the first preset humidity value, the fan is controlled to stop rotating. During fan operation, the first rotation time in the first direction and the second rotation time in the second direction are adjusted, ensuring that the first rotation time is greater than the second rotation time. This ensures that the amount of air extracted is always greater than the amount of air entering, keeping the oxygen or ethylene levels inside the refrigerator decreasing and the humidity inside the fruit and vegetable compartment increasing, thus achieving controlled atmosphere and humidity control within the compartment.

[0040] In addition, when the fan stops rotating, the entire control method is executed again to achieve cyclic control. In multiple cycles, the oxygen or ethylene in the fruit and vegetable compartment is gradually discharged, and the water vapor content inside increases, that is, the moisture content increases.

[0041] In this embodiment, by controlling the forward and reverse rotation of the fan in the fruit and vegetable compartment, the modified atmosphere and humidity control of the fruit and vegetable compartment can be achieved. By making the amount of gas discharged from the fruit and vegetable compartment less than the amount of gas entering the fruit and vegetable compartment, the humidity inside the refrigerator can be maintained while controlling the gas concentration inside the refrigerator. Thus, food is preserved through modified atmosphere and humidity control. Compared with other modified atmosphere refrigerators, the method provided in this proposal can control humidity to make the refrigerator's preservation effect better.

[0042] In some embodiments, the humidity control method for the refrigerator further includes:

[0043] Step S121: If the current humidity value is greater than the first preset humidity value, continue to control the fan to rotate in the first direction to extract the gas in the fruit and vegetable compartment;

[0044] Step S122: When the gas concentration value is less than the preset gas concentration value, control the fan to stop rotating.

[0045] Specifically, after the fan rotates in the first direction, when the current humidity in the fruit and vegetable compartment is detected, if the current humidity value is greater than the first preset humidity value, it means that the humidity in the fruit and vegetable compartment is not very low at this time. Therefore, it is not necessary to control the fan to reverse and extract air from the inside of the fruit and vegetable compartment. The fan can continue to be controlled to rotate in the first direction to adjust the gas concentration in the fruit and vegetable compartment.

[0046] When the fan runs continuously in the first direction, in order to prevent the gas concentration in the fruit and vegetable compartment from becoming too low due to continuous operation of the fan, it is necessary to continuously monitor the gas concentration value in the fruit and vegetable compartment. When the gas concentration is less than the preset gas concentration, it means that the gas has dropped to a normal level, and the fan is turned off.

[0047] In this embodiment, the control logic for ensuring sufficient humidity in the fruit and vegetable compartment is also supplemented. When the humidity is guaranteed, the fruit and vegetable compartment can be continuously evacuated to discharge excess gas to the standard range.

[0048] In some embodiments, when the gas concentration value is less than a preset gas concentration value, after the fan stops rotating, the humidity control method of the refrigerator further includes:

[0049] Step S123: Detect the current humidity level inside the fruit and vegetable compartment;

[0050] Step S124: If the current humidity value is greater than the second preset humidity value, control the fan to rotate in the first direction to extract the gas in the fruit and vegetable compartment;

[0051] Step S125: When the current humidity value is less than the second preset humidity value, control the fan to stop rotating;

[0052] The second preset humidity value is greater than the first preset humidity value.

[0053] Specifically, when the fan stops rotating, since the humidity value in the fruit and vegetable compartment previously met the first preset humidity value, it indicates that the humidity in the fruit and vegetable compartment may be high. Therefore, a second preset humidity value is set, and the humidity value in the fruit and vegetable compartment that is detected again is compared with the second preset humidity value to prevent the humidity in the fruit and vegetable compartment from being too high.

[0054] If the current humidity value is higher than the second preset humidity value, it indicates that the humidity is too high. The fan needs to be turned on again and rotated in the first direction to exhaust air from the fruit and vegetable compartment. At this time, turning on the fan is mainly to remove the water vapor inside. After turning on, the humidity value is continuously monitored. When the humidity value is lower than the second preset humidity value, it indicates that the humidity value has reached a normal level. At this time, the fan can be controlled to stop and no longer extract air.

[0055] The preset humidity values ​​in this case include a first preset humidity value and a second preset humidity value. The first preset humidity value is set to prevent the humidity from being too low, and the second preset humidity value is set to prevent the humidity from being too high. Therefore, the second preset humidity value is greater than the first preset humidity value.

[0056] Furthermore, a permeable membrane and a controlled atmosphere membrane are installed on the side walls of the fruit and vegetable compartment. The controlled atmosphere membrane is positioned where it interacts with the fan. When the fan rotates, airflow inside and outside the fruit and vegetable compartment passes through the controlled atmosphere membrane. The controlled atmosphere membrane controls the gas flow rate, ensuring that the gas flows at a uniform speed while the fan is running. In this control process, when the fan stops rotating, the oxygen concentration and humidity inside the fruit and vegetable compartment are adjusted by utilizing the natural convection between the controlled atmosphere membrane and the permeable membrane and the outside environment.

[0057] In this embodiment, after the controlled atmosphere is applied, further control logic is set to adjust the humidity in the fruit and vegetable compartment to prevent excessive humidity and adjust the humidity in the fruit and vegetable compartment in a timely manner to bring it within a reasonable range for food preservation.

[0058] In some embodiments, the humidity control method for the refrigerator further includes:

[0059] Step S131: If the gas concentration value is less than the preset gas concentration value, detect and calculate the humidity value in the fruit and vegetable compartment to obtain the average humidity value;

[0060] Step S132: Compare the average humidity value with the first preset humidity value and the second preset humidity value;

[0061] Step S133: Based on the comparison result, control the fan to rotate in the first direction or the second direction.

[0062] Specifically, when the gas concentration is lower than the preset gas concentration, it indicates that the gas concentration in the fruit and vegetable compartment is not too high, and it is not necessary to turn on the fan to remove air and reduce the gas concentration. Therefore, it is necessary to further detect the humidity in the fruit and vegetable compartment to determine whether humidity adjustment is needed.

[0063] To more accurately determine the humidity level inside the fruit and vegetable compartment, multiple humidity values ​​are detected and an average humidity value is calculated. The compartment is then adjusted based on this average humidity value. The average humidity value is directly compared with a first preset humidity value and a second preset humidity value. When the average humidity value falls between these two preset values, the humidity is considered to be within a reasonable range and no further adjustment is needed.

[0064] When obtaining the average humidity value, multiple humidity values ​​are collected at preset intervals within the refrigerator's preset cycle. The average humidity value is then calculated based on these multiple values. Specifically, the average humidity value is calculated within one refrigerator cooling cycle. Starting from the start of the refrigerator's cooling damper, humidity is collected every 30 seconds, with 30 seconds being the preset interval. The average humidity value is calculated until the next start of the cooling damper.

[0065] In this embodiment, humidity is also monitored and adjusted when the gas concentration is less than the preset gas concentration value, so as to realize comprehensive humidity control during the modified atmosphere process and make the control logic more comprehensive.

[0066] In some embodiments, based on the comparison result, the fan is controlled to rotate in a first direction or a second direction, and the humidity control method for the refrigerator further includes:

[0067] Step S141: If the average humidity is less than the first preset humidity value, control the fan to rotate in the second direction to deliver gas into the fruit and vegetable compartment.

[0068] In this embodiment, when the average humidity is less than the first preset humidity value, it indicates that the average humidity is low and humidification is needed in the fruit and vegetable compartment. Therefore, the fan is controlled to rotate in the second direction to deliver high-humidity external gas into the fruit and vegetable compartment. When the fruit and vegetable compartment is not subject to controlled atmosphere, the humidity inside the compartment can also be controlled to prevent it from being too high or too low. When the humidity is too low, the fan can be controlled to rotate for humidification.

[0069] In some embodiments, the humidity control method for the refrigerator further includes:

[0070] Step S142: Detect the current humidity level inside the fruit and vegetable compartment;

[0071] Step S143: When the current humidity value is greater than the second preset humidity value, control the fan to stop rotating and execute the humidity control method again.

[0072] In this embodiment, after the fan rotates in the second direction, to prevent over-humidification, the humidity value continues to be detected and compared with a second preset humidity value to prevent the humidity value from exceeding the maximum standard value of the second preset humidity value. If the detected humidity value is greater than the second preset humidity value, it indicates that the humidity value is too high, and the fan is controlled to stop rotating. This control logic can prevent the fan from rotating for too long and causing excessive humidification. After the fan stops rotating, to prevent subsequent fan rotation from causing the gas in the fruit and vegetable compartment to exceed the standard value, the control scheme returns to the initial state and is executed again in a loop.

[0073] In some embodiments, based on the comparison result, the fan is controlled to rotate in a first direction or a second direction, and the humidity control method for the refrigerator further includes:

[0074] Step S151: If the average humidity is greater than the second preset humidity value, control the fan to rotate in the first direction to extract the gas in the fruit and vegetable compartment.

[0075] In this embodiment, when the average humidity is greater than the second preset humidity value, it indicates that the average humidity is high and dehumidification of the fruit and vegetable compartment is required. Therefore, the fan is controlled to rotate in the first direction to extract air from the fruit and vegetable compartment. When the fruit and vegetable compartment is not subject to controlled atmosphere, the humidity inside the refrigerator can still be controlled to prevent it from being too high or too low. When the humidity is too high, the fan can be controlled to rotate for dehumidification.

[0076] In some embodiments, the humidity control method for the refrigerator further includes:

[0077] Step S152: Detect the current humidity level inside the fruit and vegetable compartment;

[0078] Step S153: If the humidity value is less than the third preset humidity value, control the fan to stop rotating;

[0079] The third preset humidity value is less than the second preset humidity value but greater than the first preset humidity value.

[0080] In this embodiment, after the fan rotates in the first direction, to prevent excessive dehumidification, the humidity value continues to be detected and compared with a third preset humidity value. If the detected humidity value is less than the third preset humidity value, it indicates that the humidity value meets the requirements, and the fan is controlled to stop rotating. The third preset humidity value is less than the second preset humidity value and greater than the first preset humidity value. Thus, when the humidity value is less than the third preset humidity value, it indicates that the humidity value is between the first and third preset humidity values, and this humidity range is suitable for food preservation. After the fan stops rotating, the oxygen concentration and humidity inside the fruit and vegetable compartment are adjusted by natural convection between the controlled atmosphere membrane and the moisture-permeable membrane of the fruit and vegetable compartment and the outside.

[0081] Secondly, this application provides a humidity control device. The refrigerator has a fruit and vegetable compartment, which is equipped with a fan that connects the fruit and vegetable compartment to the outside. The humidity control device includes: a detection module configured to detect the gas concentration value in the fruit and vegetable compartment and the current humidity value in the fruit and vegetable compartment; and a control module configured to control the fan to rotate in a first direction for a first time, control the fan to rotate in a second direction for a second time, and control the fan to stop rotating.

[0082] Thirdly, this application provides a humidity control device, including: a memory storing computer program instructions; and a processor that implements a humidity control method for a refrigerator when the computer program instructions are executed by the processor.

[0083] Fourthly, this application provides a computer-readable storage medium including instructions that, when executed on a computer, cause the computer to perform a humidity control method for a refrigerator.

[0084] Specifically, the detection module and control module enable the execution and implementation of the aforementioned humidity control method for the refrigerator. The memory, processor, and computer-readable storage medium are also capable of executing the aforementioned humidity control method for the refrigerator.
