If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

In the related art, the refrigerator keeps food or other articles in a constant low-temperature cold state to avoid spoilage, but the refrigerator only slows down the spoiling time of the food in the refrigerator, does not permanently prevent the food from spoiling, the low-temperature and low-humidity storage environment slows down chemical reaction but cannot prevent the food from spoiling, the process of spoiling the food and certain substances in the air due to the chemical reaction is slowed down by the low-temperature and low-humidity storage environment, meanwhile, the low-temperature and low-humidity storage environment also slows down the bacterial reproduction speed in the refrigerator, but the problem that vegetables are not degraded due to long storage time cannot be avoided, different foods have different appropriate storage temperature values and humidity values, and if the food such as walnuts, cashews, dried vegetables and the like is placed in a high-humidity environment, the result is suitable for the food to be reversed, and the food is accelerated to be moistened and spoiled; if food such as apple, spinach or lettuce is put in a low-humidity environment, problems such as dehydration and air drying of the food may occur, and therefore, it becomes important to store the food according to different food types.

At present, the cold-stored layer of refrigerator mainly confirms the edible material kind through image recognition technology or confirms the edible material kind that cold-stored layer was deposited through manual setting of user in advance, through the illumination environment of manual setting refrigerator, and confirm through image recognition technology that edible material kind can cause the increase of cost, humidity and the kind of food can not be monitored in real time through manual setting of user, and be unfavorable for the regulation of colour temperature through the illumination environment of manual setting refrigerator, can not guarantee humidity and the relatively stable of illumination, consequently, how under the condition of low cost, it becomes especially important to carry out accurate regulation to the humidity and the colour temperature of refrigerator.

Based on the above situation, embodiments of the present invention provide a method, an apparatus, a system and a storage medium for controlling a refrigerator, which can accurately determine the type of food through the change of humidity in a fresh-keeping drawer, and regulate and control the humidity of the refrigerator according to the type of different food, thereby realizing long-term fresh keeping of different food.

The embodiments of the present invention will be further explained with reference to the drawings.

As shown in fig. 1, fig. 1 is a flowchart of a control method of a refrigerator according to an embodiment of the present invention. The control method of the refrigerator of the embodiment of the invention comprises but is not limited to the steps S100, S200 and S300.

Step S100: under the condition that the preservation drawer is kept closed, acquiring a first humidity value measured at a first moment and a second humidity value measured at a second moment in the preservation drawer;

it should be noted that, under the state that the preservation drawer keeps closing, the preservation drawer is in the high humid state, consequently at first needs the fan to discharge the humid air in the preservation drawer, and the measurement of humidity value is carried out to the restart when the preservation drawer is in steady state, avoids the humidity influence that the preservation drawer just closed brought.

It is understood that the first time and the second time are separated by any predetermined time interval, e.g., five minutes, eight minutes, ten minutes, etc.; for example, at nine o 'clock in the morning, the humidity value of the crisper drawer is measured to be 30%, at nine o' clock in the morning, the humidity value of the crisper drawer is measured to be 50%, and then the first time is nine o 'clock, the first humidity value is 30%, the second time is nine o' clock in the evening, and the second humidity value is 50%.

Step S200: determining the humidity change rate in the preservation drawer according to the first time, the second time, the first humidity value and the second humidity value;

in some embodiments, the humidity change values of the freshness drawer at the first moment and the second moment can be obtained according to the first moment, the second moment, the first humidity value and the second humidity value, so that the humidity change rate of the freshness drawer from the first moment to the second moment is obtained, and the humidity measurement cost is reduced.

Step S300: and controlling the color temperature irradiated by the illumination assembly according to the humidity change rate and the preset change rate.

In some embodiments, under the state that the preservation drawer keeps closing, acquire first humidity value and the second humidity value that the preservation drawer measured at first moment and second moment, thereby can confirm the humidity change rate in the preservation drawer according to the humidity value change of first moment and first moment, and adjust the different colour temperatures that the illumination subassembly shines according to humidity change rate, reduce and adjust illumination environment cost, realize the different colour temperatures in the automatically regulated preservation drawer, thereby the freshness date of different edible materials is prolonged.

It should be noted that, in this embodiment, the humidity values such as the first humidity value and the second humidity value may be obtained by measuring with a humidity sensor disposed in the fresh-keeping drawer, and this embodiment is not limited in particular.

It is understood that the color temperature includes blue light, red light, yellow light, white light, etc., and the embodiment is not particularly limited.

In some embodiments, the humidity difference from the first time to the second time is obtained by subtracting the second humidity value measured at the second time from the first humidity value measured at the first time, and then the time difference is obtained according to the first time and the second time, and the humidity difference is divided by the time difference to obtain the humidity change rate of the crisper drawer from the first time to the second time.

It should be noted that the preset rate may be obtained by measuring and calculating the humidity value of the fresh-keeping drawer at any time interval in a state where the fresh-keeping drawer is kept closed and no food material is stored; or the humidity value of the preservation drawer is measured and calculated at any time interval under the state that the preservation drawer is kept closed and food materials with small influence on the environmental humidity are stored; or set for the worker, and the embodiment is not particularly limited.

It can be understood that, since the switch of the refrigerator has an influence on the change of the humidity value of the fresh-keeping drawer, the preset rate and the parameters such as the first humidity value and the second humidity value are measured when the fresh-keeping drawer is closed.

Referring to fig. 2, fig. 2 is a flowchart illustrating a specific method for step S300 in fig. 1, where step S300 may include, but is not limited to, steps S310 to S330.

It should be noted that the preset change rate includes a first preset change rate and a second preset change rate.

Step S310: when the humidity change rate is in a first preset interval, controlling the illumination assembly to illuminate red light;

step S320: when the humidity change rate is in a second preset interval, controlling the illumination assembly to illuminate blue light;

step S330: when the humidity change rate is in a third preset interval, the illumination assembly is closed;

it should be noted that the first preset change rate is smaller than the second preset change rate, the first preset change rate and the second preset change rate form a second preset interval, a value exceeding the second preset change rate forms a first preset interval, and a value lower than the first preset change rate forms a third preset interval.

In some embodiments, when it is determined that the humidity change rate is within the first preset interval, which indicates that the humidity inside the fresh-keeping drawer changes greatly, the illumination assembly needs to be controlled to illuminate red light with a red color temperature, where the red light can activate the green plants to perform photosynthesis to activate the activity of a synthetase related to chlorophyll, so that the synthesis of chlorophyll is accelerated by the green plants, the synthesis of soluble sugar and chlorophyll is promoted, and the nutritive value of the food material is increased.

In some embodiments, when it is determined that the humidity change rate is within the second preset interval, which indicates that the humidity change inside the fresh-keeping drawer is small, the illumination component can be controlled to irradiate blue light with a blue color temperature, wherein the blue light can increase the expression of the antioxidant substance genes in the fruits, and the increase of nutrients such as anthocyanin and polyphenol in the storage process is realized.

In some embodiments, when it is determined that the humidity change rate is within the third predetermined interval, which indicates that the humidity inside the fresh-keeping drawer is substantially unchanged, the illumination assembly is turned off, thereby saving energy.

Referring to fig. 3, fig. 3 is a flowchart of a control method of a refrigerator according to another embodiment of the present invention, which includes, but is not limited to, step S400.

Step S400: and controlling the illumination intensity irradiated by the illumination assembly according to the humidity change rate and the number of the illumination assemblies.

In some embodiments, the illumination intensity irradiated by the illumination assemblies is controlled according to the humidity change rate in the preservation drawer and the number of the illumination assemblies, so that uniform illumination in the preservation drawer is realized, and the conditions of nonuniform illumination and the like are avoided.

Referring to fig. 4, fig. 4 is a flowchart illustrating a specific method for step S400 in fig. 3, where step S400 may include, but is not limited to, steps S410 to S420.

Step S410: under the condition that the illumination assemblies illuminate red light, determining the opening number of the illumination assemblies and the illumination intensity of each illumination assembly so as to enable the total illumination intensity in the preservation drawer to be equal to a first illumination intensity corresponding to a first preset interval;

step S420: and under the condition that the illumination assemblies illuminate blue light, determining the opening number of the illumination assemblies and the illumination intensity of each illumination assembly so as to enable the total illumination intensity in the preservation drawer to be equal to a second illumination intensity corresponding to a second preset interval.

In some embodiments, in the case that the illumination assemblies illuminate red light, the number of the turned-on illumination assemblies and the illumination intensity of each illumination assembly are determined, so that the total illumination intensity in the fresh-keeping drawer is equal to a first illumination intensity corresponding to a first preset interval; and under the condition that the illumination assemblies irradiate blue light, the opening number of the illumination assemblies and the illumination intensity of each illumination assembly are determined, so that the total illumination intensity in the preservation drawer is equal to the second illumination intensity corresponding to the second preset interval, and the phenomenon of uneven illumination is avoided.

It should be noted that the first illumination intensity and the second illumination intensity are related to the light flux, wherein the light radiation power of the first illumination intensity is between 200 mw and 300 mw, and the light radiation power of the second illumination intensity is greater than 400 mw.

In some embodiments, the first illumination intensity is less than the second illumination intensity.

The red light may be 660 nm red light with an illumination intensity of 0.6 mw/cm, 650 nm red light with an illumination intensity of 0.6 mw/cm, 680 nm red light with an illumination intensity of 0.6 mw/cm, or the like, and the wavelength of the red light may be in a range from 625 nm to 740 nm; the blue light may be blue light with a wavelength of 450 nm and an intensity of 1.4 mw/cm, blue light with a wavelength of 410 nm and an intensity of 1.4 mw/cm, or blue light with a wavelength of 470 nm and an illumination intensity of 1.4 mw/cm, and the wavelength range of the blue light is 400 nm to 480 nm, which is not particularly limited in this embodiment.

Referring to fig. 5, fig. 5 is a flowchart of a control method of a refrigerator according to another embodiment of the present invention, which includes, but is not limited to, steps S500 to S600.

Step S500: determining the food material type of the food material stored in the fresh-keeping drawer according to the humidity change rate and the preset rate;

step S600: and adjusting the humidity of the fresh-keeping drawer according to the food material types.

In some embodiments, the food material types stored in the preservation drawer are determined according to the humidity change rate and the preset rate, the accuracy of judging the food material types is improved, and the humidity of the preservation drawer is adjusted according to different food material types, so that the preservation time of different food materials is prolonged, the food material identification cost is reduced, and the humidity value of the storage environments of different food material types is automatically adjusted.

Referring to fig. 6, fig. 6 is a flowchart illustrating a specific method for step S500 in fig. 5, where step S500 may include, but is not limited to, steps S510 to S530.

The food material types include a first food material type, a second food material type and a third food material type, wherein the transpiration of the food materials corresponding to the first food material type, the second food material type and the third food material type is reduced in sequence.

In some embodiments, the first food material may be vegetables with high transpiration of food materials, such as spinach, lettuce, and leek, the second food material may be fruits with medium transpiration of food materials, such as apple, orange, and strawberry, the third food material may be dried vegetables and dried fruits with low transpiration of food materials, such as dried mushroom, dried okra, and cinnamon, and the third food material may be dry goods or nuts, such as walnut, hazelnut, and cashew, which are not limited in this embodiment.

It should be noted that the first food material may be a plurality of greengrocery, such as sweet potato leaves, leeks, water spinach, leaf lettuce, etc., and the greengrocery has a higher transpiration effect, so that the humidity change rate is faster due to a larger difference in humidity change at a certain time interval; the second food material may be various fruits, such as apple, banana, cantaloupe, etc., and due to the transpiration of the fruits, etc., the humidity change difference is smaller than that of the first food material at the same time interval as the food material of the first food material, so the humidity change rate is smaller than that of the first food material, and the third food material is a food material with less moisture, such as dry goods, dried fruits or nuts, etc., so the humidity change is stable and needs to be stored in a dry environment.

It can be understood that the food material transpiration rate of the first food material is the highest, so that the humidity of the preservation drawer can be quickly increased to more than 95%, the food material transpiration of the second food material is moderate, the moisture content of the third food material is lower and is of a porous internal structure, and the humidity of the preservation drawer can be reduced.

Step S510: when the humidity change rate is larger than the preset rate, determining that the food material type is a first food material type;

step S520: when the humidity change rate is equal to the preset rate, determining that the food material type is a second food material type;

step S530: and when the humidity change rate is smaller than the preset rate, determining the food material type as a third food material type.

In some embodiments, when the humidity change rate is greater than the preset rate, it indicates that more water vapor is released in the food material storage process, which results in a greater humidity change of the fresh-keeping drawer, and thus the food material type is determined to be the first food material type; when the humidity change rate is equal to the preset rate, the moisture released in the food material storage process is medium, the transpiration of the food material is low or no transpiration is generated, and the influence on the humidity of the preservation drawer is small, so that the food material type is determined to be a second food material type; when the humidity change rate is smaller than the preset rate, the moisture content of the food material is low, and the humidity of the preservation drawer is reduced due to the porous internal result, so that the food material type is determined to be a third food material type.

In some embodiments, the number of the lighting assemblies can be increased or decreased according to the food material type, for example, when the number of the lighting assemblies is ten, in case of storing spinach in the fresh food drawer, only five lighting assemblies can be turned on for lighting, so as to maintain the light radiation power of the total lighting intensity in the fresh food drawer between 200 mw and 300 mw; under the condition that the apples are stored in the preservation drawer, because the illumination intensity required by the apples is high, eight illumination assemblies are required to be opened for illumination, so that the total illumination intensity in the preservation drawer is higher than 400 milliwatts, the illumination intensity requirements of different food types are met, and the nutritive values of different food materials are increased to the maximum extent.

Referring to fig. 7, fig. 7 is a flowchart illustrating a specific method for step S600 in fig. 5, where step S600 may include, but is not limited to, steps S610 to S630.

Step S610: acquiring a real-time humidity value of the fresh-keeping drawer;

in some embodiments, the real-time humidity value of the preservation drawer is obtained in real time through a humidity sensor inside the preservation drawer, so that the humidity of the preservation drawer corresponding to the food material types can be conveniently adjusted subsequently.

It will be appreciated that the real-time humidity values are measured by a humidity sensor in the crisper drawer.

Step S620: determining a food material humidity interval according to the food material types;

the food humidity interval is a storage humidity interval suitable for the food.

Step S630: and adjusting the humidity in the fresh-keeping drawer according to the real-time humidity value and the food material humidity interval.

In some embodiments, the real-time humidity value of the preservation drawer is firstly obtained, then the food material humidity interval corresponding to the food material type is determined according to the food material type, and finally the humidity in the preservation drawer is adjusted according to the real-time humidity value and the food material humidity interval, so that the preservation time of the food material is prolonged.

Referring to fig. 8, fig. 8 is a flowchart illustrating a specific method for step S630 in fig. 7, where step S630 may include, but is not limited to, step S631 and step S633.

It should be noted that, the fresh-keeping drawer includes the fan, and the edible material humidity interval of first edible material class is first humidity interval, and the edible material humidity interval of second edible material class is second humidity interval, and the edible material humidity interval of third edible material class is third humidity interval.

Step S631: when the food material type is determined to be a first food material type and the real-time humidity value exceeds a first humidity interval, controlling the fan to operate so as to adjust the humidity value in the preservation drawer to the first humidity interval;

in some embodiments, when the food material type is determined to be a first food material type, and the real-time humidity value exceeds the maximum value of the first humidity interval, it is determined that the real-time humidity value in the preservation drawer is too high, the humidity value in the preservation drawer needs to be reduced, the fan needs to be controlled to operate to refrigerate the preservation drawer, and the humidity value in the preservation drawer is reduced to the first humidity interval through replacement of dry and wet air; when the food material type is determined to be the first food material type and the real-time humidity value of the preservation drawer is lower than the minimum value of the first humidity interval, it is indicated that the real-time humidity value in the preservation drawer is too low, the humidity value in the preservation drawer needs to be increased, and the fan needs to be controlled to operate to discharge the humid air into the preservation drawer, so that the preservation of the food material of the first food material type is realized.

It should be noted that, when it is determined that the food material type is the first food material type and the real-time humidity value is located in the first humidity interval, it is determined that the real-time humidity value in the fresh-keeping drawer meets the humidity storage requirement of the first food material type, and then dry and wet air replacement is not required.

Step S632: when the food material type is determined to be a second food material type and the real-time humidity value exceeds a second humidity interval, controlling the fan to operate so as to adjust the humidity value in the preservation drawer to the second humidity interval;
