[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, humidifying the refrigerator introduces high-temperature, high-humidity gases, which affects the opening and closing of the refrigerator's cooling door, impacting refrigeration and ultimately affecting internal temperature control and preservation. Currently, there is no method that can simultaneously regulate humidity and temperature. Summary of the Invention

[0004] This application provides a refrigerator humidity control method, apparatus, device, and readable storage medium thereof, so as to achieve the technical effect of humidifying the inside of the refrigerator without affecting the temperature regulation inside the refrigerator.

[0005] In a first aspect, this application provides a refrigerator equipped with a fresh air fan, a refrigerator damper, and a return air damper. The humidity control method includes: detecting the humidity value inside the refrigerator at multiple times, and calculating the average humidity value based on the humidity value; comparing the average humidity value with a first preset humidity value and a second preset humidity value, wherein the first preset humidity value is less than the second preset humidity value; and adjusting the opening temperature or stopping temperature of the refrigerator damper and controlling the rotation of the fresh air fan based on the comparison results.

[0006] In one possible implementation, the humidity values ​​inside the refrigerator at multiple times are detected, and the average humidity value is calculated based on the humidity values. This includes: acquiring the humidity values ​​at multiple times within a preset cycle of the refrigerator at a preset first interval; and calculating the average humidity value from the multiple humidity values.

[0007] In one possible implementation, the opening temperature or shutdown temperature of the refrigeration damper is adjusted according to the comparison results, including: if the average humidity is less than a first preset humidity value, the opening temperature of the refrigeration damper is increased by the first temperature value; if the average humidity is greater than a second preset humidity value, the shutdown temperature of the refrigeration damper is decreased by the second temperature value.

[0008] In one possible implementation, controlling the fresh air fan to rotate based on the comparison result includes: if the average humidity is less than a first preset humidity value, controlling the fresh air fan to rotate in a first direction to deliver gas into the refrigerator; detecting the current humidity value inside the refrigerator; and when the current humidity value is greater than the first preset humidity value, controlling the fresh air fan to stop rotating and executing the humidity control method again.

[0009] In one possible implementation, adjusting the opening or stopping temperature of the refrigerator damper and controlling the rotation of the fresh air fan based on the comparison result includes: if the average humidity value is greater than a second preset humidity value, controlling the fresh air fan to rotate in a second direction to extract gas from the refrigerator, wherein the first direction is opposite to the second direction; when the temperature inside the refrigerator reaches the lowest value, detecting the current humidity value inside the refrigerator; comparing the current humidity value with the second preset humidity value, and controlling the rotation of the fresh air fan based on the comparison result.

[0010] In one possible implementation, comparing the current humidity value with a second preset humidity value and controlling the rotation of the fresh air fan according to the comparison result includes: if the current humidity value is greater than the second preset humidity value, controlling the fresh air fan to rotate in a second direction; when the current humidity value is less than or equal to the second preset humidity value, controlling the fresh air fan to stop rotating and executing the humidity control method again.

[0011] In one possible implementation, the current humidity value is compared with a second preset humidity value, and the fresh air fan is controlled to rotate based on the comparison result, including: if the current humidity value is less than or equal to the second preset humidity value, the fresh air fan is controlled to stop rotating, and the humidity control method is executed again.

[0012] Secondly, this application provides a humidity control device. The refrigerator is equipped with a fresh air fan, a refrigerator air door, and a return air door. The humidity control device includes: a detection module configured to detect the humidity value inside the refrigerator at multiple times; a calculation module configured to calculate the average humidity value based on the humidity value; a comparison module configured to compare the average humidity value with a first preset humidity value and a second preset humidity value; and a control module configured to adjust the opening temperature or stopping temperature of the refrigerator air door and control the rotation of the fresh air fan.

[0013] Thirdly, this application provides a humidity control device, including: a memory storing computer program instructions; and a processor that implements a refrigerator humidity control method when the computer program instructions are executed by the processor.

[0014] Fourthly, this application provides a computer-readable storage medium including instructions that, when executed on a computer, cause the computer to perform a refrigerator humidity control method.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art:

[0016] The refrigerator is equipped with a cooling damper, which supplies cold air to the interior for cooling. The fresh air fan can rotate in two opposite directions: a first direction and a second direction. When the fresh air fan rotates in the first direction, it supplies high-humidity air to the refrigerator, humidifying it. When it rotates in the second direction, it draws air out of the refrigerator, dehumidifying it. The refrigerator also has a return air damper to prevent excessive pressure differences between the inside and outside of the refrigerator due to high air content inside the refrigerator during the air intake and exhaust processes.

[0017] First, the humidity level inside the refrigerator is measured. To ensure accuracy, multiple humidity values ​​are averaged. This average value is then compared to two preset humidity levels. If the average humidity is less than the second preset value but greater than the first, the humidity is within a reasonable range and is sufficient to keep food fresh. Conversely, if the average humidity is less than the first preset value, the humidity is too low; if it is greater than the second preset value, the humidity is too high. In both cases, the fresh air fan is activated to humidify or dehumidify the refrigerator by supplying or drawing in humidified air.

[0018] Because the air supplied to the refrigerator by the fresh air fan is not only highly humid but also at a high temperature, it can cause temperature fluctuations inside the refrigerator, affecting the opening and closing of the refrigerator's air vents. Therefore, before controlling the fresh air fan's operation, the refrigerator's preset start and stop temperatures should be adjusted based on a humidity comparison to ensure that the refrigerator's temperature regulation is not affected by the fresh air fan's operation.

[0019] This solution pre-adjusts the opening and closing temperature values ​​of the refrigerator air damper based on the humidity comparison results. This prevents unnecessary opening or closing of the refrigerator air damper after the fresh air fan starts running, ensuring that the temperature and humidity control inside the refrigerator can work together without affecting each other.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0030] To address the technical problem that humidification and cooling of the refrigerator door cannot be performed simultaneously and interfere with each other in the prior art, this application provides a refrigerator humidity control method, device, equipment and its readable storage medium, which can achieve the technical effect of humidifying the inside of the refrigerator without affecting the temperature regulation inside the refrigerator.

[0031] In some embodiments, Figure 1 This is a flowchart illustrating a refrigerator humidity control method. The solution provides a refrigerator humidity control method, which includes a fresh air fan, a refrigerator air damper, and a return air damper. The refrigerator humidity control method comprises:

[0032] Step S100: Detect the humidity value inside the refrigerator at multiple time points, and calculate the average humidity value based on the humidity value;

[0033] Step S200: Compare the average humidity value with the first preset humidity value and the second preset humidity value respectively, wherein the first preset humidity value is less than the second preset humidity value;

[0034] Step S300: Based on the comparison results, adjust the opening temperature or shutdown temperature of the refrigeration damper and control the rotation of the fresh air fan.

[0035] For details, see Figure 2The refrigerator is equipped with a refrigeration air damper, which supplies cold air to the refrigerator for cooling. The fresh air fan can rotate in two opposite directions: a first direction and a second direction. When the fresh air fan rotates in the first direction, it supplies high-humidity air to the refrigerator for humidification; when it rotates in the second direction, it draws air out of the refrigerator for dehumidification. The refrigerator also has a return air damper to prevent high air content and excessive pressure difference between the inside and outside of the refrigerator caused by the simultaneous intake and exhaust of air.

[0036] First, the humidity level inside the refrigerator is measured. To ensure accuracy, multiple humidity values ​​are averaged. This average value is then compared to two preset humidity levels. If the average humidity is less than the second preset value but greater than the first, the humidity is within a reasonable range and is sufficient to keep food fresh. Conversely, if the average humidity is less than the first preset value, the humidity is too low; if it is greater than the second preset value, the humidity is too high. In both cases, the fresh air fan is activated to humidify or dehumidify the refrigerator by supplying or drawing in humidified air.

[0037] Because the air supplied to the refrigerator by the fresh air fan is not only highly humid but also at a high temperature, it can cause temperature fluctuations inside the refrigerator, affecting the opening and closing of the refrigerator's air vents. Therefore, before controlling the fresh air fan's operation, the refrigerator's preset start and stop temperatures should be adjusted based on a humidity comparison to ensure that the refrigerator's temperature regulation is not affected by the fresh air fan's operation.

[0038] This solution pre-adjusts the opening and closing temperature values ​​of the refrigerator air damper based on the humidity comparison results. This prevents unnecessary opening or closing of the refrigerator air damper after the fresh air fan starts running, ensuring that the temperature and humidity control inside the refrigerator can work together without affecting each other.

[0039] In some embodiments, the humidity values ​​inside the refrigerator at multiple time points are detected, and an average humidity value is calculated based on the humidity values, including:

[0040] Step S110: Within the refrigerator's preset cycle, obtain humidity values ​​at multiple times according to a preset first interval.

[0041] Step S120: Calculate the average value of multiple humidity values ​​to obtain the average humidity value.

[0042] Specifically, to better describe the average humidity of the refrigerator over a period of time, multiple humidity values ​​are measured within a preset cycle, and the average of these values ​​is calculated. The preset cycle starts from the opening of the refrigerator air vent, and humidity is collected every 30 seconds until the next opening of the refrigerator air vent. The average of these humidity values ​​is then calculated, and this average is the humidity average. If the interval between two refrigerator air vent openings exceeds 2 hours, the humidity is calculated as an integral over a 2-hour period.

[0043] In this embodiment, the average humidity is calculated periodically, making the humidity measurement more accurate and the method more precise.

[0044] In some embodiments, adjusting the opening temperature or stopping temperature of the refrigeration damper based on the comparison results includes:

[0045] Step S311: If the average humidity is less than the first preset humidity value, control the opening temperature of the refrigeration door to increase by the first temperature value;

[0046] Step S321: If the average humidity is greater than the second preset humidity value, control the shutdown temperature of the refrigeration damper to decrease the second temperature value.

[0047] Specifically, when the average humidity is lower than the first preset humidity value, it indicates that the humidity inside the refrigerator is low. In this case, the fresh air fan needs to rotate in the first direction to send high-humidity, high-temperature air from outside into the refrigerator. While the high-humidity air entering the refrigerator can bring the internal humidity to the preset range, the high temperature will cause the refrigerator door to open, cooling the refrigerator. This cooling will not only affect the internal temperature regulation but also further impact the internal humidity regulation. Therefore, it is necessary to prevent the refrigerator door from opening at this time. To prevent the refrigerator door from opening, this solution adjusts the opening temperature of the refrigerator door by increasing the first temperature value. By raising the opening temperature of the refrigerator door, even if high-temperature air is introduced, it will not trigger the opening of the refrigerator door, ensuring the original temperature regulation inside the refrigerator and avoiding a reduction in humidification effect after cooling.

[0048] When the average humidity value exceeds the second preset humidity value, it indicates that the humidity inside the refrigerator is high. In this case, the fresh air fan needs to be controlled to rotate in the second direction to expel the high-humidity, low-temperature gas from the refrigerator. After the high-humidity gas is extracted, the humidity inside the refrigerator will reach the preset range. However, the resulting low temperature will cause the normally operating refrigerator damper to stop. This stoppage will not only affect the internal temperature regulation but also further impact the internal humidity regulation. Therefore, it is necessary to keep the refrigerator damper running. To prevent the refrigerator damper from stopping, this solution adjusts the stop temperature of the refrigerator damper to a lower second temperature value. This way, even if high-temperature gas is extracted, the refrigerator damper will not stop, maintaining the original temperature regulation inside the refrigerator and preventing a reduction in dehumidification efficiency after cooling stops.

[0049] In this embodiment, based on the comparison between the average humidity value and the preset value, the opening temperature and stopping temperature of the refrigerator door are first adjusted to avoid the influence of the fresh air fan on the internal temperature control of the refrigerator during operation, so that the refrigerator can control humidity and adjust temperature at the same time.

[0050] In some embodiments, controlling the rotation of the fresh air fan based on the comparison result includes:

[0051] Step S312: If the average humidity is less than the first preset humidity value, control the fresh air fan to rotate in the first direction and deliver gas into the refrigerator;

[0052] Step S313: Detect the current humidity level inside the refrigerator;

[0053] Step S314: When the current humidity value is greater than the first preset humidity value, control the fresh air fan to stop rotating and execute the humidity control method again.

[0054] Specifically, 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 refrigerator. Therefore, the fresh air fan is controlled to rotate in the first direction to deliver high humidity gas into the refrigerator.

[0055] After the fresh air fan rotates in the first direction, to prevent it from running continuously, the humidity value is continuously monitored and compared with the first preset humidity value. If the detected humidity value is greater than the first preset humidity value, it means that the humidity value has been adjusted to the normal range, and the fan is controlled to stop rotating.

[0056] After the fresh air fan stops rotating, the natural convection at the fresh air fan or the return air in the refrigerator is used to make the humidity and temperature in the refrigerator reach a dynamic balance, and the system is controlled to return to the beginning and run again for circulation.

[0057] In this embodiment, the humidity inside the refrigerator can be controlled to prevent it from being too high or too low. When the humidity is too low, the fresh air fan can be controlled to rotate to humidify, and the fresh air fan can also be prevented from rotating for too long.

[0058] In some embodiments, adjusting the opening or stopping temperature of the refrigeration damper and controlling the rotation of the fresh air fan based on the comparison results includes:

[0059] Step S322: If the average humidity is greater than the second preset humidity value, control the fresh air fan to rotate in the second direction to extract the gas in the refrigerator, wherein the first direction is opposite to the second direction;

[0060] Step S323: When the temperature inside the refrigerator reaches its lowest value, detect the current humidity level inside the refrigerator;

[0061] Step S324: Compare the current humidity value with the second preset humidity value, and control the fresh air fan to rotate according to the comparison result.

[0062] Specifically, when the average humidity value is greater than the second preset humidity value, it indicates that the average humidity value is too high and dehumidification is needed inside the refrigerator. Therefore, the fresh air fan is controlled to rotate in the second direction to extract high-humidity air from the refrigerator. After the fresh air fan rotates in the second direction, to prevent the fresh air fan from rotating continuously, the humidity value continues to be monitored and compared with the second preset humidity value. The rotation of the fresh air fan is adjusted based on the comparison result.

[0063] In some embodiments, comparing the current humidity value with a second preset humidity value and controlling the rotation of the fresh air fan based on the comparison result includes:

[0064] Step S411: If the current humidity value is greater than the second preset humidity value, control the fresh air fan to rotate in the second direction;

[0065] Step S412: When the current humidity value is less than or equal to the second preset humidity value, control the fresh air fan to stop rotating and execute the humidity control method again.

[0066] Specifically, if the detected humidity value is greater than the second preset humidity value, it indicates that the humidity value has not been adjusted to the normal range, and the humidity inside the refrigerator is still very high. In this case, the fresh air fan continues to rotate in the second direction to continuously dehumidify until the detected humidity value is less than or equal to the second preset humidity value, at which point the fresh air fan stops rotating. After the fresh air fan stops rotating, natural convection at the fresh air fan or return air from inside the refrigerator is used to achieve a dynamic balance between humidity and temperature inside the refrigerator, and the system returns to its initial state and repeats the cycle.

[0067] In some embodiments, comparing the current humidity value with a second preset humidity value and controlling the rotation of the fresh air fan based on the comparison result includes:

[0068] Step S421: If the current humidity value is less than or equal to the second preset humidity value, control the fresh air fan to stop rotating and execute the humidity control method again.

[0069] Specifically, if the detected humidity value is less than or equal to the second preset humidity value, it indicates that the humidity value has been adjusted to the normal range, and the fan will stop rotating. After the fresh air fan stops rotating, natural convection at the fresh air fan or return air from inside the refrigerator is used to achieve dynamic balance of humidity and temperature inside the refrigerator, and the system will return to its initial state and repeat the cycle.
