Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0042] Dry food ingredients refer to food ingredients that have been dehydrated. They have low water content, rich nutrients, and unique flavors. They play a key role in many fields such as cooking and health care. The general storage method for users is to store them in a cool place, but this causes the quality of dry food ingredients to deteriorate, nutrients to be lost, flavor substances to escape, color to be dull and matte, and taste to deteriorate. For this reason, storing dry food in a refrigerator has become a new way of preservation for people. However, the refrigerator mainly relies on cooling the temperature in the storage space to achieve a temperature suitable for preserving food ingredients and delay the spoilage of food ingredients. This has a good preservation effect on fresh meat and fruits and vegetables. However, in the preservation of special ingredients such as dry food, due to the relatively high humidity in the refrigerator's cold storage room, the dry food is easy to regain moisture, and it is difficult to achieve long-term high-quality preservation in the refrigerator.

[0043] To this end, the present application embodiment provides a food preservation device 1000, which is applied to a refrigerator 10. Figure 1 As shown, the food preservation device 1000 includes:

[0044] A first box body 110 having a first storage chamber S1; and

[0045] The moisture absorption module 120 is disposed on the first box body 110 and is configured to absorb moisture in the first storage chamber S1.

[0046] In the technical solution of the embodiment of the present application, the food preservation device 1000 is used in the refrigerator 10, which includes a first box body 110; the first box body 110 has a first storage cavity S1, and the first box body 110 is provided with a moisture absorption module 120, which is used to absorb moisture in the first storage cavity S1, so as to reduce the humidity in the first storage cavity S1 to be lower than the humidity in the refrigerator 10, so that the dry food ingredients can be stored in a relatively reduced humidity environment, that is, they can be stored in an environment with relatively low temperature and low humidity, effectively extending the shelf life of the dry food ingredients and maintaining the quality of the dry food.

[0047] In the specific implementation process, Figure 8 As shown, the refrigerator 10 has a fresh-keeping liner 11; the humidity in the fresh-keeping liner 11 is relatively high. The fresh-keeping liner 11 can be a refrigerated liner for preserving vegetables and the like. The food preservation device 1000 is placed in the fresh-keeping liner 11, which can be understood as a special area in the refrigerated liner for preserving dry food ingredients. After placing the food preservation device 1000 in the fresh-keeping liner 11, the moisture absorption module 120 can absorb the internal moisture and reduce the humidity in the first storage chamber S1, so that the humidity in the first storage chamber S1 can be reduced to a level lower than that of the fresh-keeping liner 11. That is, the dry food ingredients are stored in a low temperature and low humidity environment, which is conducive to the preservation of the dry food ingredients.

[0048] In some embodiments, the food preservation device 1000 may be a separate device, which is installed in a refrigerator by a user when in use; in other embodiments, the food preservation device 1000 may be a structure provided in a refrigerator to store dry food.

[0049] In an embodiment, the moisture absorption module 120 has a moisture absorption function. For example, the moisture absorption module 120 with a desiccant can be installed in the food preservation device 1000; for another example, the moisture absorption module 120 includes a moisture absorption salt and a storage structure for storing the moisture absorption salt, such as calcium chloride, magnesium chloride, sodium sulfate or montmorillonite.

[0050] As an optional implementation of the above embodiment, Figure 2 As shown, a heating module 140 is further provided on the first box 110, and the heating module 140 is configured to heat the moisture absorption module 120 to evaporate the moisture in the moisture absorption module 120. In an embodiment, the heating module 140 heats the moisture absorption module 120 to evaporate the moisture in the moisture absorption module 120.

[0051] It should be noted that, in some cases, when the dry food material is tea leaves, etc., the humidity in the first storage chamber S1 needs to be maintained within a certain range. When the humidity in the first storage chamber S1 reaches the range or is lower than the lower limit of the range, the heating module 140 can be turned on so that the moisture absorption module 120 no longer absorbs moisture or even releases some moisture, and the humidity in the first storage chamber S1 is maintained within the range or raised to the range again, so that the dry food material can be stored within a suitable humidity range.

[0052] For example, in an embodiment, the heating module 140 is connected to the controller signal. The controller may be a control panel of the refrigerator 10, or a controller of a sub-bag of the food preservation device 1000. The controller is configured to obtain the food type, determine the humidity storage range according to the food type; obtain the current humidity in the first storage chamber S1; and control the heating module 140 to start when the current humidity is within the humidity storage range or is lower than the lower limit of the humidity storage range.

[0053] In some embodiments, the heating module 140 may be a constant temperature heating device, that is, the heating module 140 performs constant temperature heating on the moisture absorption module 120. The heating module 140 may heat the moisture absorption module 120 by heat conduction; for example, by thermal contact with the moisture absorption module 120. The heating module 140 may also heat the moisture absorption module 120 by heat radiation, for example, the heating module 140 is installed on the first wall 111 and maintains a certain distance from the moisture absorption module 120.

[0054] In some embodiments, the heating module 140 may also be embedded in the moisture absorption module 120 to generate heat from the inside of the moisture absorption module 120 to remove internal moisture.

[0055] As an alternative implementation of the above embodiment, refer to Figure 2 As shown, the heating module 140 includes a heating element 141, and the heating element 141 is arranged around the moisture absorption module 120. In an embodiment, the heating element 141 is arranged around the through hole to uniformly heat the moisture absorption module 120 in the circumferential direction, so that the moisture absorption module 120 is evenly heated, and the moisture in the moisture absorption module 120 is evenly evaporated.

[0056] For example, in an embodiment, the heating element 141 can be constructed as a hollow structure, which is installed in the through hole; the moisture absorption module 120 is arranged in the hollow structure. In some embodiments, the heating element 141 can be a spiral structure, which is spirally wound around the outer periphery of the moisture absorption module 120.

[0057] In an embodiment, the heating element 141 may be in a sheet shape, a wire shape, etc. The heating element 141 may be heated by electric energy.

[0058] As an optional implementation of the above embodiment, Figure 3 As shown, the moisture absorption module 120 has a microporous channel 121, which is filled with moisture absorption salt and connects the first storage chamber S1 and the outside of the first box 110. The microporous channel 121 can be used as a channel for air flow, connecting the first storage chamber S1 and the outside of the first box 110 to facilitate the discharge of evaporated water, and is also filled with moisture absorption salt to increase the filling capacity of the moisture absorption salt.

[0059] In the embodiment, the hygroscopic salt's hygroscopic principle: water vapor quickly diffuses into the hygroscopic module 120 through the microporous channel 121, and contacts the hygroscopic salt particles filled therein. The hygroscopic salt quickly captures water molecules to undergo a deliquescence reaction, converting gaseous water into a crystalline hydrate for storage, and continuously absorbing water to reduce the humidity in the first storage chamber S1, thereby achieving dehumidification. The desorption principle of the hygroscopic salt: when the heating module 140 can be used to increase the temperature, the crystalline hydrate of the hygroscopic salt is decomposed by heat or the hygroscopic salt no longer absorbs the water seal, and releases the previously adsorbed water molecules, which become water vapor and diffuse into the external space through the micropores, thereby increasing the air humidity, for example, the humidity in the first storage chamber S1 can be increased again.

[0060] As an optional implementation of the above embodiment, the pore size of the microporous channel 121 is 1-10 microns. The microporous channel 121 with a pore size of 1-10 microns takes into account air fluidity and also facilitates filling of sufficient hygroscopic salt in the hygroscopic module 120.

[0061] As an optional implementation of the above embodiment, Figure 3 As shown, the hygroscopic module 120 includes a skeleton 122, and the skeleton 122 is formed with the microporous channel 121, and the skeleton 122 is fixed in the through hole. In the embodiment, the skeleton 122 can be a ceramic skeleton 122, a metal organic skeleton 122, etc. After the hygroscopic salt, such as calcium chloride, is made into fine particles and dispersed and filled into the pores formed by the microporous channels 121 of the porous ceramic skeleton 122, the ceramic skeleton 122 restricts its flow and agglomeration to avoid agglomeration into large particles after moisture absorption and deliquescence, which affects the moisture absorption effect and material life, and constitutes a stable and efficient hygroscopic module 120. The porous ceramic skeleton 122 made of diatomaceous earth is sintered at high temperature to form abundant and evenly distributed microporous channels 121 inside.

[0062] Combination Figure 2 and Figure 5 As shown, the first box body 110 includes a first wall body 111, and the first wall body 111 is provided with a through hole connected to the first storage chamber S1; the moisture absorption module 120 is arranged in the through hole. The first box body 110 is also provided with a fan module 130, and the fan module 130 is configured to drive the air with evaporated water to be discharged to the outside of the first box body 110. In an embodiment, the fan module 130 is fixed to the first wall body 111 by a screw. In an embodiment, the fan module 130 includes an axial flow fan. In an embodiment, the fan module 130 can be installed on the inner side of the first wall body 111, and is configured to guide the air in the first storage chamber S1 to flow to the outside, that is, blowing; in an embodiment, the fan module 130 can be installed on the outer side of the first wall body 111, and is configured to guide the air in the first storage chamber S1 to flow to the outside, that is, sucking.

[0063] The fan module 130 can discharge the air with evaporated water to the outside of the first box body 110. For example, when the moisture absorption module 120 is saturated with water and cannot reduce the humidity of the first storage chamber S1, the heating module 140 is in a heating state and the fan module 130 is in an operating state. For example, in an embodiment, the heating module 140 and the fan module 130 are started at a fixed time to discharge the moisture in the moisture absorption module 120 at a fixed time, so that the moisture absorption module 120 can absorb water, and absorb the moisture in the first storage chamber S1 to keep the first storage chamber S1 in a relatively dry state.

[0064] In an embodiment, the controller is further configured to: if the current humidity is greater than the upper limit of the humidity storage range, control the fan module 130 to be in operation. At this time, the air in the first storage chamber S1 can enter the moisture absorption module 120 to dehumidify the air in the first storage chamber S1.

[0065] In some embodiments, when the current humidity is greater than the upper limit of the humidity storage range, and after the humidity of the first storage chamber S1 maintains the current humidity for a preset time, the fan module 130 is controlled to be in an operating state, and the heating module 140 is controlled to be in a heating state, at this time, while removing the moisture in the moisture absorption module 120, the air in the first storage chamber S1 enters the moisture absorption module 120, and the air in the first storage chamber S1 is dehumidified. That is, when the moisture absorption module 120 is saturated and the humidity in the first storage chamber S1 cannot be reduced, the fan module 130 is started, and the heating module 140 is heated to reduce the humidity in the first storage chamber S1.

[0066] As an optional implementation of the above embodiment, Figure 5 As shown, the food preservation device 1000 further includes a second box 150, which is connected to the first wall 111; the second box 150 has a second storage chamber S2; the second storage chamber S2 is connected to the first storage chamber S1 through the moisture absorption module 120. In the embodiment, the first storage chamber S1 is mainly used to store dry goods, and the second storage chamber S2 is mainly used to store wet goods. The humid air in the first storage chamber S1 can be guided to the second storage chamber S2 through the fan module 130.

[0067] For example, in the embodiment, when the fan module 130 is controlled to be in the running state and the heating module 140 is controlled to be in the heating state, the evaporated moisture enters into the second storage chamber S2, and the second storage chamber S2 is humidified.

[0068] Further, in the embodiment, a first baffle and a second baffle may be respectively provided on both sides of the through hole, and the first baffle and the second baffle are respectively movably connected to the first wall 111, and both have states of closing the through hole and opening the through hole. For example, in the embodiment, when dry goods are stored in the first storage chamber S1, the baffle on the side of the first storage chamber S1 may be opened, and the baffle on the side of the second storage chamber S2 may be closed, so that the moisture absorption module 120 absorbs moisture in the first storage chamber S1. For example, in the embodiment, when the humidity in the second storage chamber S2 is too high and is not conducive to the storage of wet goods, the baffle on the side of the first storage chamber S1 may be closed, and the baffle on the side of the second storage chamber S2 may be opened, so that the moisture absorption module 120 absorbs moisture in the second storage chamber S2 and prevents humid air from entering the first storage chamber S1. For another example, in the embodiment, when the moisture absorption module 120 is saturated, the first baffle and the second baffle are opened simultaneously, and the heating module 140 and the fan module 130 are started to discharge the evaporated moisture into the second storage chamber S2 and reduce the humidity in the first storage chamber S1.

[0069] As an optional implementation of the above embodiment, Figure 2 and Figure 5As shown, the first wall 111 is provided with an air duct S3, and the air duct S3 connects the first storage chamber S1 and the second storage chamber S2; the first wall 111 is movably provided with a door panel 160, and the door panel 160 has a first state of opening the air duct S3 and a second state of closing the air duct S3. In an embodiment, the first storage chamber S1 and the second storage chamber S2 can be directly connected through the air duct S3 to achieve direct exchange of air between dry and wet areas. For example, when the first storage chamber S1 needs to be temporarily used to store wet goods, the door panel 160 can be opened to inject high-humidity air into the first storage chamber S1. When storing dry goods in the first storage chamber S1, if the humidity therein is lower than the minimum humidity required for food preservation (the lower limit of the humidity storage range determined by the corresponding food type), the door panel 160 can be opened to inject high-humidity air into the first storage chamber S1 to increase the internal humidity to at least the minimum system. When storing dry goods in the first storage chamber S1, if the humidity therein is lower than the humidity preservation range required for food preservation or higher than the maximum humidity required for food preservation (the upper limit value determined by the corresponding food type), the door panel 160 is closed.

[0070] As an alternative implementation of the above embodiment, Figure 7 As shown, the first storage chamber S1 is also provided with an illumination module, and the illumination module is configured to emit light of different wavelengths. Light of a specific wavelength is used to react with the chemical substances in the dry food ingredients by photochemical reaction. Taking green tea as an example, when tea polyphenols are excited by light in a specific wavelength range (such as blue light of 420-460nm), more active free radicals will be produced. These free radicals can combine with harmful free radicals produced in tea leaves, thereby slowing down the speed of oxidation reaction and maintaining the freshness and quality of tea leaves. For wolfberry, it is rich in carotenoids and wolfberry polysaccharides. Carotenoids mainly absorb green light of 480-520nm. Under the action of light, the conjugated double bonds in its molecular structure can be supplemented with energy, making the molecules more stable and preventing them from decomposing due to oxidation, thereby maintaining the bright color of wolfberry. Under light excitation, the spatial structure of the molecular chain of wolfberry polysaccharide can be optimized, reducing the breakage and degradation of sugar chains and prolonging its stability during storage. Crocin and crocin in saffron are its main active ingredients and pigment sources. Under the irradiation of 560-600nm yellow light, the chemical bonds of these ingredients can absorb light energy, causing changes in the vibration and rotation states of the molecules, enhancing the interaction between molecules, improving their ability to resist oxidation and decomposition, and maintaining the color and efficacy of saffron.

[0071] In addition, the scattering of light can allow light waves to penetrate into the deep tissues of food, activate internal cell activity, and increase their energy metabolism levels, thereby maintaining the normal physiological functions of cells and delaying cell aging and death.

[0072] As an optional implementation of the above embodiment, the illumination module 170 is controlled by a controller. For example, the food preservation device 1000 or the refrigerator 10 also includes a controller, and the controller is used to control the illumination module. Among them, the controller is used to control the illumination module 170 to emit a wavelength adapted to the type of food to be preserved as needed. The illumination module 170 combines the high monochromaticity of the tunable laser diode with the easy controllability of the LED. The tunable laser diode itself can be adjusted within a certain wavelength range, usually with a narrow line width and a high power density. When combined with an LED, the LED is first used to provide a wide range of basic light, and then the tunable laser diode is used to perform fine wavelength adjustment on this basis. The controller can first determine the approximate light output range of the LED according to the preservation requirements of different dry food ingredients, and then use the tunable laser diode to perform precise wavelength fine-tuning. For example, when preserving green tea, LED can provide a basic red light range of 600-700nm, and then use a tunable laser diode to accurately adjust the wavelength to the wavelength range of 640-680nm that is most suitable for chlorophyll stability, thereby achieving intelligent and precise light wavelength control.

[0073] As an optional implementation of the above embodiment, the illumination module 170 is controlled by a controller. For example, the food preservation device 1000 or the refrigerator 10 further includes a controller, and the controller is used to control the illumination module. Figure 7 As shown, the first box body 110 is further provided with a weight sensor 190, and the weight sensor 190 is used to measure the weight of the food to be stored; and / or, the first box body 110 is also provided with a temperature sensor, and the temperature sensor is used to measure the temperature in the first storage cavity S1; wherein, the controller is used to control the light intensity and / or light time of the light module 170 according to the weight and / or temperature of the food as needed.

[0074] In an embodiment, the illumination module 170 is disposed on the second wall 112 (top wall) of the box, and the weight sensor 190 is disposed on the third wall 113 (bottom wall) of the box. The illumination intensity and / or illumination time are determined according to the weight of the food, that is, the amount of food, so as to store the food under appropriate illumination conditions. And / or, the illumination intensity and / or illumination time are adjusted according to the temperature in the first storage chamber S1 to avoid temperature rise due to too high illumination intensity or too long illumination time, or temperature drop due to too low illumination intensity or too short illumination time.

[0075] For example, when it is detected that the temperature of the environment in which the green tea is located rises due to a brief fluctuation in the refrigeration of the refrigerator 10, the light wave intensity is appropriately increased and the irradiation interval is shortened to activate the tea leaves' self-repair and preservation functions and resist the impact of temperature changes.

[0076] In an embodiment, a first correspondence between light intensity and / or illumination time and weight is stored in a storage medium. A second correspondence between light intensity and / or illumination time and temperature is stored in a storage medium. The first correspondence and the second correspondence are determined based on experimental data.

[0077] In addition, in some embodiments, a third corresponding relationship is provided between weight and temperature as well as light intensity and / or light time. The third corresponding relationship is the light intensity and / or light time required when the gravity is certain and the temperature is certain. For example, the gravity is in the first gravity interval, the temperature is in the first temperature interval, the light intensity is the first light intensity, and the light time is the first light time. For example, the gravity is in the first gravity interval, the temperature is in the second temperature interval, the light intensity is the second light intensity, and the light time is the second light time. For example, the gravity is in the second gravity interval, the temperature is in the second temperature interval, the light intensity is the third light intensity, and the light time is the third light time. Specifically, the gravity interval, the temperature interval, the light intensity, and the light time are determined according to experiments, and the determined relationship can be stored in a storage medium as a curve, a table, etc.

[0078] As an optional implementation of the above embodiment, the food preservation device 1000 also includes a nutrient agent sustained-release module 180, and the nutrient agent sustained-release module 180 is arranged in the first storage chamber S1. The nutrient agent sustained-release module 180 may include a vitamin C sustained-release capsule. The vitamin C sustained-release capsule can be wrapped with natural polymer materials or polymers such as gelatin, β-cyclodextrin, hydroxypropyl methylcellulose, etc., and slowly releases antioxidant substances during the storage process. When the sustained-release capsule is used up, the user can be reminded to replace it through the smart app interface.

[0079] In some other embodiments, the nutrient sustained-release module 180 may also include a plant polyphenol sustained-release module.

[0080] Based on the food preservation device 1000 proposed in the above embodiment, the present application further proposes a food preservation system, which includes:

[0081] A database, the database is used to store suitable environmental data for different ingredients, the environmental data including humidity and / or temperature;

[0083] In an embodiment, a suitable humidity range and / or temperature range is matched according to the type of food stored to adjust the humidity and / or temperature in the first storage chamber S1 to the suitable humidity range and / or temperature range so that the food is in a suitable humidity and temperature environment.

[0084] For example, according to the ideal humidity environment of various dry goods in the original storage or late growth period, a digital humidity, temperature and light model is constructed. For example: the storage humidity of green tea is set at 40%-48% and the temperature is 5-8°C; the humidity of wolfberry is set at 38%-42% and the temperature is 0-5°C; the suitable storage humidity of saffron is 42%-46% and the storage temperature is 5-8°C. A high-sensitivity humidity sensor and temperature sensor group are used to monitor the humidity and temperature of each point in the first storage chamber S1 and make timely adjustments.

[0085] In an embodiment, the database may be a cloud database or a local database.

[0086] Based on the above embodiments, Figure 8 As shown, the embodiment of the present application further proposes a refrigerator 10 , which includes a food preservation device 1000 as proposed in the above-mentioned embodiment, and the food preservation device 1000 is arranged in a fresh-keeping inner tank 11 of the refrigerator 10 .

[0087] In an embodiment, the humidity in the fresh-keeping liner 11 is relatively high. The fresh-keeping liner 11 can be a refrigerated liner for preserving vegetables and the like. The food preservation device 1000 is placed in the fresh-keeping liner 11, which can be understood as a special area in the refrigerated liner for preserving dry food ingredients. After placing the food preservation device 1000 in the fresh-keeping liner 11, the moisture absorption module 120 can absorb the internal moisture and reduce the humidity in the first storage chamber S1, so that the humidity in the first storage chamber S1 can be reduced to a level lower than that of the fresh-keeping liner 11. That is, the dry food ingredients are stored in a low temperature and low humidity environment, which is conducive to the preservation of the dry food ingredients.

[0088] In addition, when used by the user, the food preservation device 1000 can also be used to store other food, reducing space waste. The user can remove the moisture absorption module 120 according to the specific food, and adjust the lighting module 170 to a suitable lighting condition for storing food. In addition, the food preservation device 1000 can also be disassembled.

[0089] In an embodiment, the food preservation device 1000 may be constructed as a drawer structure.

[0090] In the above embodiments, the module using porous ceramic composite hygroscopic salt can dehumidify and humidify the dry and wet spaces respectively. Two partitionable storage spaces are set up in the refrigerator 10 according to the characteristics of different ingredients; multiple temperature and humidity sensors can be set up in the dry food preservation space to accurately control the temperature and humidity of the space; the vitamin C slowly released by the sustained-release capsule can inhibit the oxidation of dry food ingredients and slow down the deterioration of food ingredients; the high monochromaticity of the tunable laser diode combined with LED technology can accurately control the wavelength and intensity of light; the illumination module 170 can turn on the light wave effect according to the needs of different ingredients to stabilize the material structure of chlorophyll, polysaccharides, anthocyanins, etc. in dry food ingredients, and slow down the loss of nutrients.
