Description

Technical Field

[0001] The present invention relates to the technical field of storage, and in particular to storage equipment and a humidity control method and device thereof. Background Art

[0002] In the relevant technologies, the storage of fresh food requires the humidity of the storage space to be maintained above a very high standard. Taking food preservation as an example, the preservation technology is mainly divided into two categories: water preservation and water-free preservation. In water-free preservation technology, the main factor affecting the survival rate of food is humidity. Taking the refrigerator as an example, in order to achieve survival, it is necessary to create a high humidity preservation environment with a relative humidity value greater than 95% RH (relative humidity value) in the refrigerator. If a humidity sensor with a lower detection range is used, it is easy to experience sensor drift in a high humidity environment, resulting in reduced humidity detection accuracy and affecting storage effect.

[0008] The present invention also provides a computer program.

[0009] A first embodiment of the present invention provides a storage device, comprising:

[0010] The box body is formed with a storage space suitable for storing items;

[0015] According to the storage device provided by the embodiment of the first aspect of the present invention, a humidity sensor having a detection interval less than a second humidity value is used to obtain a first humidity value within the storage space. Then, through processing and calculation, a controller is enabled to control a humidity control device based on the calculation result, so that the humidity control device maintains the humidity within the storage space at a state greater than the first humidity, thereby enabling water-free storage of food materials in a high-humidity storage environment. Furthermore, by using a humidity sensor having a detection interval less than the second humidity value in conjunction with an algorithm of the controller, control of a high-humidity storage environment can be achieved using a humidity sensor having a detection interval less than the second humidity value, thereby reducing the storage cost of the storage device.

Through such a control method, the adjustment and control of the humidity control device in the storage device can be achieved more accurately, so that the control accuracy of the storage device is higher, and the precise water-free preservation of food ingredients can be achieved. Since the humidity requirements in the storage device are high, and the humidity sensor with a low detection range is prone to sensor drift in a high humidity environment, this control method can also solve the sensor drift problem of the humidity sensor with a low detection range in a high humidity environment, thereby achieving the purpose of using the humidity sensor with a low detection range to detect and control the high humidity environment in the storage device, and can reduce the storage cost of the storage device.

[0073] See also Figure 1 , an embodiment of the first aspect of the present invention provides a storage device, including a box body 406, a cover body 410, a humidity control device 412, a humidity sensor 414 and a controller; wherein, a storage space 408 for storing things is formed in the box body 406, the humidity control device 412 is installed in at least one of the box body 406 and the cover body 410, the humidity control device 412 is used to maintain the humidity in the storage space 408 greater than a first humidity, the humidity sensor 414 is installed in at least one of the box body 406 and the cover body 410, the detection range of the humidity sensor 414 is less than the second humidity, the humidity sensor 414 is used to detect the first humidity value in the storage space 408, and the controller is used to control the humidity control device 412 based on the first humidity value when executing the program.

[0074] According to the storage device provided by the embodiment of the first aspect of the present invention, a humidity sensor 414 having a detection interval less than the second humidity value is used to obtain a first humidity value within the storage space 408. Then, through processing and calculation, a controller is enabled to control the humidity control device 412 based on the calculation result, so that the humidity control device 412 maintains the humidity within the storage space 408 at a state greater than the first humidity, thereby achieving water-free storage of food materials through a high-humidity storage environment. In addition, by using a humidity sensor 414 having a detection interval less than the second humidity value in conjunction with an algorithm of the controller, the humidity sensor 414 having a detection interval less than the second humidity value can be used to control the high-humidity storage environment, thereby reducing the storage cost of the storage device.

[0075] Please continue to see Figure 1 The storage device can utilize a refrigerator's keep-alive drawer, which includes a box body 406, a lid 410, a humidity control device 412, a humidity sensor 414, and a controller. Box body 406 and lid 410 together form a storage space 408 within the storage device. Specifically, storage space 408 is formed within box body 406, allowing users to place food directly within box body 406. Lid 410, mounted on box body 406, cooperates with box body 406 to form a sealed space. In this embodiment of the present invention, the first humidity level can be 95% RH, and the second humidity level can be 90% RH.

[0076] Humidity control device 412 can be an atomizing assembly or a humidifying assembly. By providing humidity control device 412, the humidity of storage space 408 within box body 406 can be adjusted and maintained above a baseline of 95% RH. By maintaining the humidity of storage space 408 within box body 406 above a high baseline, fresh food can be preserved without water in a high-humidity environment. Humidity control device 412 can be installed on at least one of box body 406 and lid 410.

[0077] In an embodiment of the present invention, the humidity control device 412 is installed on the cover body 410. Accordingly, a water box 416 is also provided on the cover body 410. The humidity control device 412 is installed in the water box 416. By providing the water box 416 on the cover body 410, it is convenient for the user to add water to the water box 416.

[0078] Humidity sensor 414 is used to detect a first humidity value within storage space 408. In this embodiment of the present invention, humidity sensor 414 employs a humidity sensor 414 with a detection range less than 90% RH. It will be appreciated that, in this embodiment of the present invention, the upper limit of the detection range of humidity sensor 414 is less than the lower limit of the relative humidity required in storage space 408. That is, in this embodiment of the present invention, humidity sensor 414 with a low detection range is used to control humidity control device 412, causing humidity control device 412 to maintain the relative humidity in storage space 408 above a baseline of greater than 95% RH.

[0079] See also Figure 1 The humidity sensor 414 is mounted on the side of the cover 410 facing the box body 406. The humidity sensor 414 is also mounted away from the humidity control device 412. For example, the humidity control device 412 can be mounted on a side of the keep-alive drawer away from the door. Accordingly, the humidity sensor 414 is mounted on a side of the keep-alive drawer close to the door. This prevents the humidity sensor 414 from drifting in high humidity environments.

[0080] After receiving the first humidity value obtained by the humidity sensor 414, the controller calculates and outputs the corresponding control logic and inputs it into the humidity control device 412. The humidity control device 412 adjusts the relative humidity in the storage space 408 based on the control logic. The specific control method in the controller is as follows.

[0081] See also Figure 1 An image acquisition device 415 is further provided on the side of the cover 410 facing the box body 406 , and the image acquisition device 415 can acquire image information of the food in the storage space 408 .

[0082] A temperature sensor is also mounted on cover 410. This allows the controller to more accurately control humidity control device 412 based on the first humidity value obtained by humidity sensor 414 and the temperature value of storage space 408 obtained by the temperature sensor. This is because, considering the impact of temperature on humidity, integrating the temperature sensor on cover 410 ensures that the controller can output more precise control logic.

[0083] An operation panel 418 is also provided on the side of the cover 410 facing away from the box body 406. The operation panel 418 can be electrically connected to the humidity control device 412. The operation panel 418 can be used to start and stop the keep-alive function of the storage device, and can also control the opening and closing of the humidity control device 412.

[0084] Of course, the above storage devices are only examples, and other devices that can achieve the keep-alive function are also feasible, and they will not be listed here one by one.

[0085] like Figure 2 As shown, a second embodiment of the present invention provides a humidity control method for a storage device, comprising:

[0086] Step 100: Obtain a first humidity value detected by the humidity sensor 414;

[0087] Step 200: Calculate a second humidity value inside the storage space 408 based on the first humidity value;

[0088] Step 300: Based on the second humidity value, control the humidity control device 412 in the storage device to make the humidity in the storage space 408 greater than the first humidity.

[0089] According to a second aspect of the present invention, a humidity control method for a storage device is provided. A humidity sensor 414 obtains a first humidity value and, based on the correspondence between the first humidity value and the second humidity value within the storage space 408, calculates a second humidity value for the storage space 408. After calculating the second humidity value for the storage space 408, the humidity control device 412 is controlled based on the second humidity value to maintain the humidity within the storage space 408 above the first humidity value. This control method allows for more precise regulation and control of the humidity control device 412 within the storage device, resulting in higher control accuracy and precise water-free preservation of food. Due to the high humidity requirements in storage devices, humidity sensors 414 with a low detection range are prone to sensor drift in high humidity environments. This control method can also address this sensor drift issue, thereby achieving the goal of using humidity sensors with a low detection range 414 to detect and control high humidity environments within the storage device, thereby reducing storage costs.

[0090] Please continue to see Figure 2 In step 100 , since the humidity sensor 414 is disposed on the cover, the first humidity value at the top of the storage space 408 can be obtained through the humidity sensor 414 .

[0091] It should be noted that in this step, humidity sensor 414 can be positioned at the location with the lowest humidity in storage space 408. In an embodiment of the present invention, humidity control device 412 for humidifying storage space 408 is positioned at the top of the storage device. Similarly, humidity sensor 414 for detecting the humidity in storage space 408 is also installed at the top of the storage device. To reduce the storage cost of the storage device, the location with the lowest humidity in the storage device is determined to be a location on the storage device farthest from humidity control device 412. Therefore, humidity sensor 414 is positioned at the side of the top of the storage device, farthest from humidity control device 412. This arrangement allows humidity sensor 414 in a low detection range to detect the first humidity value at a location with lower humidity. This ensures that humidity sensor 414 in a low detection range does not experience sensor drift at this location, thereby ensuring the accuracy of humidity sensor 414 in a low detection range in detecting the first humidity value.

[0092] In step 200 , a second humidity value at a location in the storage space 408 for storing fresh food is calculated using the first humidity value obtained in step 100 .

[0093] It is understood that in step 200, the second humidity value at the location in the storage space 408 for storing fresh food is calculated. This is because, within the same storage space 408, the first humidity value at the top of the storage space 408 and the second humidity value at the bottom of the storage space 408 have the same fluctuation trend over time, so the second humidity value can be calculated and fitted based on the first humidity value.

[0094] In step 200, step 210 is included, using the first humidity value as a variable and calculating the second humidity value through a humidity conversion function.

[0095] It is understandable that in step 210, the first humidity value is used as a variable and is substituted into the humidity conversion function, and the second humidity value at the top of the storage space 408 can be obtained through calculation of the humidity conversion function.

[0096] In the embodiment of the present invention, the second humidity value can be calculated in at least four ways:

[0097] Calculation method 1:

[0098] In this calculation method, the second humidity value is calculated by the following formula:

[0099] Hy=f(Hx);

[0100] Wherein, Hy is the second humidity value, Hx is the first humidity value, and f is the humidity conversion coefficient.

[0101] For example, at the 5th second, the first humidity value of the top of the storage space 408 obtained by the humidity sensor 414 is 88% RH.

[0102] Substituting the first humidity value of 88% RH into the humidity conversion function Hy = f(Hx), and calculating the humidity conversion coefficient by multiplying the first humidity value of 88% RH by the humidity conversion coefficient, the second humidity value at the bottom of storage space 408 at the 5th second can be calculated. For example, if the humidity conversion coefficient is 1.055, the second humidity value at the bottom of storage space 408 at the 5th second can be calculated. This calculation method can be used to calculate the second humidity value at the bottom of storage space 408 at a specific time based on the first humidity value.

[0103] Calculation method 2:

[0104] In this calculation method, before step 200, step 190 is also included, obtaining the temperature value of the storage space 408 in the storage device; step 210 also includes step 211, using the first humidity value and the temperature value as variables, and calculating the second humidity value through a humidity conversion function.

[0105] In step 190 , the temperature value of the storage space 408 may be acquired by a temperature sensor, which may be provided on the storage device.

[0106] In this calculation method, the second humidity value is calculated by the following formula:

[0107] Hy = f(Hx, Tx);

[0108] Wherein, Hy is the second humidity value, Hx is the first humidity value, Tx is the temperature value, and f is the humidity conversion coefficient.

[0109] For example, at the 5th second, the first humidity value of the top of the storage space 408 obtained by the humidity sensor 414 is 88% RH, and the temperature value in the storage space 408 obtained by the temperature sensor is 13°C.

[0110] Substitute the first humidity value of 88% RH and the temperature value of 13°C into the humidity conversion function Hy=f(Hx, Tx). The second humidity value at the bottom of the storage space 408 at the 5th second can be calculated by combining the first humidity value of 88% RH, the temperature value of 13°C, and the humidity conversion coefficient. For example, if the humidity conversion coefficient is 1.055, the second humidity value at the bottom of the storage space 408 at the 5th second can be obtained. In this calculation method, the influence of temperature on humidity changes is taken into account, and the temperature value parameter is added to the calculation method. Through this calculation method, the second humidity value at the bottom of the storage space 408 at a specific point in time can be calculated based on the first humidity value and the temperature value.

[0111] Calculation method three:

[0112] In this calculation method, the second humidity value is calculated by the following formula:

[0113] Hy = f(Hx, Hx-1...Hx-n);

[0114] Wherein, Hy is the second humidity value, Hx is the first humidity value, n is the detection time of the first humidity value, and f is the humidity conversion coefficient.

[0115] For example, at the 5th second, the first humidity value at the top of the storage space 408 obtained by the humidity sensor 414 is 88.5% RH, at the 4th second, the first humidity value at the top of the storage space 408 obtained by the humidity sensor 414 is 88.2% RH, at the 3rd second, the first humidity value at the top of the storage space 408 obtained by the humidity sensor 414 is 87.8% RH, and at the 2nd second, the first humidity value at the top of the storage space 408 obtained by the humidity sensor 414 is 88.1% RH.

[0116] Substituting the first humidity values ​​of 88.5% RH, 88.2% RH, 87.8% RH, and 88.1% RH obtained at the 5th, 4th, 3rd, and 2nd seconds, respectively, into the humidity conversion function Hy = f(Hx, Hx-1…Hx-n), the second humidity value at the bottom of storage space 408 at the 5th second can be calculated by combining the four different first humidity values ​​with the humidity conversion coefficient. For example, if the humidity conversion coefficient is 1.055, the second humidity value at the bottom of storage space 408 at the 5th second can be calculated. Compared to the first and second calculation methods, this calculation method can calculate the second humidity value at the bottom of storage space 408 at a specific time point based on multiple first humidity values ​​at several time points before the current time point, resulting in a more accurate calculation result.

[0117] The reason is that the humidity at the top of the storage space 408 decreases relatively quickly due to the influence of the degree of fog diffusion. From the perspective of fog diffusion, there is a certain degree of time lag in the changing relationship between the humidity at the top of the storage space 408 and the humidity at the bottom of the storage space 408. Therefore, if it is necessary to calculate the second humidity value at the bottom of the storage space 408 at the 5th second, it can be calculated based on the first humidity value by fitting the first humidity values ​​detected at multiple time points forward.

[0118] Calculation method 4:

[0119] In this calculation method, before step 200, step 190 is also included, obtaining the temperature value of the storage space 408 in the storage device; step 210 also includes step 211, using the first humidity value and the temperature value as variables, and calculating the second humidity value through a humidity conversion function.

[0120] In step 190 , the temperature value of the storage space 408 may be acquired by a temperature sensor, which may be provided on the storage device.

[0121] In this calculation method, the second humidity value is calculated by the following formula:

[0122] Hy=f(Hx, Hx-1...Hx-n, Tx);

[0123] Wherein, Hy is the second humidity value, Hx is the first humidity value, n is the detection time of the first humidity value, Tx is the temperature value, and f is the humidity conversion coefficient.

[0124] For example, at the 5th second, the first humidity value at the top of the storage space 408 obtained by the humidity sensor 414 is 88.5% RH, at the 4th second, the first humidity value at the top of the storage space 408 obtained by the humidity sensor 414 is 88.2% RH, at the 3rd second, the first humidity value at the top of the storage space 408 obtained by the humidity sensor 414 is 87.8% RH, and at the 2nd second, the first humidity value at the top of the storage space 408 obtained by the humidity sensor 414 is 88.1% RH.

[0125] Correspondingly, for example, at the 5th second, the temperature value of the top of the storage space 408 obtained by the temperature sensor is 12.8°C, at the 4th second, the temperature value of the top of the storage space 408 obtained by the temperature sensor is 13.1°C, at the 3rd second, the temperature value of the top of the storage space 408 obtained by the temperature sensor is 13.2°C, and at the 2nd second, the temperature value of the top of the storage space 408 obtained by the temperature sensor is 12.9°C.

[0126] Substitute the first humidity values ​​of 88.5% RH, 88.2% RH, 87.8% RH, and 88.1% RH obtained at the 5th, 4th, 3rd, and 2nd seconds, respectively, and the temperature values ​​of 12.8° C., 13.1° C., 13.2° C., and 12.9° C. obtained at the 5th, 4th, 3rd, and 2nd seconds, respectively, into the humidity conversion function Hy=f(Hx, Hx-1…Hx-n, Tx). By calculating the four different first humidity values ​​and temperature values ​​with the humidity conversion coefficient, the second humidity value at the bottom of the storage space 408 at the 5th second can be obtained. For example, if the humidity conversion coefficient is 1.055, the second humidity value at the bottom of the storage space 408 at the 5th second can be obtained. Compared with the third calculation method, this calculation method can calculate the second humidity value at the bottom of the storage space 408 at a specific time point based on multiple first humidity values ​​and temperature values ​​at several time points before the current time point, and the calculation result is more accurate.

[0127] The reason for this is that the humidity at the top of storage space 408 decreases relatively quickly due to the diffusion of fog. As a result, there is a certain time lag between the humidity changes at the top and bottom of storage space 408. Furthermore, to account for the impact of temperature on humidity changes, a temperature parameter is added to the calculation method. That is, to calculate the second humidity value at the bottom of storage space 408 at the fifth second, the calculation can be performed by fitting the first humidity values ​​and temperature values ​​detected at multiple time points forward based on the first humidity value.

[0128] In step 300 , based on the second humidity values ​​obtained by the above-mentioned calculation methods, the humidity control device 412 is controlled to humidify the storage space 408 so that the humidity in the storage space 408 is greater than the first humidity.

[0129] It is understandable that in step 300, the high humidity environment can be adjusted and controlled based on the humidity sensor 414 with a lower detection range, thereby reducing the humidity control cost of the storage device.

[0130] According to one embodiment of the present invention, the proportional coefficient is obtained by computational learning of at least one of a support vector model (SVM), a gradient boosting model (XGBoost), a linear regression model, and a mechanical simulation model.

[0131] See also Figure 1 In an embodiment of the present invention, a humidity control device 412 and a humidity sensor 414 are provided on the storage device. The humidity sensor 414 is provided on a side of the storage device away from the humidity control device 412 .

[0132] By setting the humidity sensor 414 on the side of the storage device away from the humidity control device 412, the detection requirement of obtaining the first humidity value at the top of the storage space 408 by using the humidity sensor 414 with a low detection range can be met. At the same time, it can also effectively avoid the occurrence of sensing drift phenomenon of the humidity sensor 414 with a low detection range in a high humidity environment.

[0133] See also Figure 3 According to a third aspect of the present invention, a humidity control device is provided, comprising:

[0134] An acquisition module 400 is configured to acquire a first humidity value;

[0135] a calculation module 402 for calculating a second humidity value inside the storage space 408 based on the first humidity value;

[0136] The control module 404 is configured to control the humidity control device 412 of the storage device based on the second humidity value so that the humidity in the storage space 408 is greater than the first humidity.

[0137] According to the humidity control device for storage equipment provided by the third embodiment of the present invention, by providing an acquisition module 400, a calculation module 402, and a control module 404, a second humidity value can be calculated based on the first humidity value, and then the humidity control device 412 can be controlled by the second humidity value. This allows for more precise adjustment and control of the humidity control device 412 in the storage device, resulting in higher control accuracy for the storage device and accurate water-free preservation of food ingredients. This control device can also solve the problem of sensor drift that occurs in a low detection range humidity sensor 414 in a high humidity environment, thereby reducing storage costs.
