Referring to fig. 1, fig. 1 is a schematic view of a refrigerator 1 according to an embodiment of the present invention. The present invention provides a refrigerator 1, and the refrigerator 1 may generally include a cabinet 10 and a door 20. The case 10 may include a housing located at the outermost side of the overall refrigerator 1 to protect the overall refrigerator 1, and a plurality of inner containers. The plurality of inner containers are wrapped by the shell, and heat insulation materials (forming a foaming layer) are filled in the space between the plurality of inner containers and the shell so as to reduce the outward heat dissipation of the inner containers. Each liner may define a forwardly open storage compartment 12, and the storage compartments 12 may be configured as refrigerated compartments, freezer compartments, temperature change compartments, etc., with the number and function of particular storage compartments 12 being configurable according to the needs in advance.

The number of the door bodies 20 can be the same as that of the inner containers, namely, each storage compartment 12 with the inner container opened forwards can be opened and closed by the corresponding door body 20. The door 20 is movably provided in front of the case 10, and for example, the door 20 may be provided at one side of the front of the case 10 in a hinged manner, and the storage compartment 12 may be opened and closed in a pivotal manner.

The storage compartment 12 is provided with cooling capacity by a refrigeration system to achieve a refrigerated, frozen, temperature-variable storage environment. The refrigeration system may be a refrigeration cycle system composed of a compressor, a condenser, a throttle device, an evaporator 30, and the like.

In some embodiments, the refrigerator 1 may further include a storage device 30, and the storage device 30 may be disposed inside the door body 20, particularly inside the door body 20 for opening and closing the refrigerating compartment.

Because the storage device 30 is arranged on the inner side of the door body 20 and can be opened or closed along with the door body 20, a user can place food or drink with higher use frequency in the storage device 30 without taking in the storage compartment 12 of the refrigerator 1, and the storage device is simple and convenient.

Further, the storage device 30 further defines a storage space 32, and a plurality of storage locations may be disposed in the storage space 32, so as to be used for correspondingly placing the beverage on the storage locations, so as to accurately detect the storage state of the beverage.

Referring to fig. 2, fig. 2 is a functional block diagram of a refrigerator 1 according to an embodiment of the present invention. Further, the refrigerator 1 may further include a controller 40, and the controller 40 may include a processor 42 and a memory 44. The processor 42 may be a Central Processing Unit (CPU) or a digital processing unit (DSP), etc., and the memory 44 stores a machine executable program 442, which when executed by the processor 42 enables the beverage storage control method of any one of the following embodiments.

Referring to fig. 3, fig. 3 is a flowchart of a beverage storage control method according to one embodiment of the present invention. The beverage storage control method may further comprise the steps of:

step S310, obtaining storage information of the beverage, wherein the storage information comprises the type, specification weight, quality guarantee period and production date of the beverage.

Step S320, the storage state of the beverage is identified according to the storage information of the beverage, and the storage state comprises an unsealed state and an unsealed state.

Step S330, based on the beverage in the unsealed state, it is determined whether a picking event occurs on the beverage, where the picking event is an event that the beverage is replaced in the refrigerator 1 after being taken out of the refrigerator 1.

Step S340, under the condition that the taking event occurs, determining the remaining storage duration of the beverage according to the occurrence duration and the occurrence times of the taking event.

In step S310, the beverage storage information may be obtained by an input device, which may receive the type of food material manually input by the user, and the input device may be a manual key, a code scanning identification device, or the like. In a usage scenario, a plurality of common beverage types may be pre-stored in the memory 44 of the refrigerator 1 for the user to select when inputting, and the user may enter the system according to the storage information (type, specification weight, quality guarantee period, production date, etc.) on the beverage package.

In step S320, since there are some beverages in the market at present that have a larger volume and are used for multiple times by users, once they are unsealed, the beverage in the unsealed state is inferior to the beverage in the unsealed state in storage under the same storage conditions. In this step, therefore, the stored state of the beverage is identified based on the stored information of the beverage, so that the stored state of the beverage can be adjusted in a targeted manner in the subsequent step.

In step S330, determining whether a beverage taking event has occurred may be implemented by a sensor, such as a pressure sensor, a light sensor, or the like. Taking the pressure-sensitive sensor as an example, a pressure-sensitive sensor is arranged at each storage level, when a user takes away the beverage from the storage level, the pressure of the pressure-sensitive sensor is reset to zero, and after a period of time, when the user relocates the beverage to the storage level, the pressure-sensitive sensor detects a certain pressure, so that the beverage taking event can be judged.

In step S330, the acquisition of the occurrence time period and the occurrence number may be implemented by a timer and a counter, respectively, and the recording time node may refer to the actions of the above-mentioned sensor. For example, when the user takes the drink from the storage place, when the pressure of the pressure-sensitive sensor is reset to zero, the timer starts to count, when the user relocates the drink to the storage place, the pressure-sensitive sensor detects a certain pressure, and the timer stops counting, so that the occurrence time of one taking event is obtained. Similarly, when the user takes the drink from the storage position, when the pressure of the pressure-sensitive sensor is reset to zero, after a period of time, when the user relocates the drink to the storage position, the pressure-sensitive sensor detects a certain pressure, and the count value of the counter is +1 at this time, so that the occurrence times of the taking event are accumulated.

The inventors realized that: for beverages with large capacity and multiple uses, the user cannot always keep the beverage in the optimal storage environment in the use process, and even if the beverage in the quality guarantee period is unqualified, the use experience of the user is affected.

For example, for dairy products, storage may be for 45 days in a refrigerated environment at 2-6 ℃. During use, the user needs to take the milk product out of the refrigerating chamber of the refrigerator 1 for dispensing, and also consider that there are situations where the user forgets to replace the taken milk product in the refrigerator 1, etc., which may aggravate the milk product spoilage progress, so that the beverage in the shelf life is already disqualified.

Therefore, in step S330 and step S340, if the picking event occurs on the beverage in the unsealed state, the beverage is considered to deviate from the optimal storage environment, and the quality guarantee period of the beverage is further revised according to the occurrence times and occurrence time of the picking event, and then the remaining storage time of the beverage is redetermined according to the revised quality guarantee period, so that the user refers to the redetermined remaining storage time of the beverage to avoid the phenomenon that the beverage in the quality guarantee period is unqualified.

In summary, in the beverage storage control method of the present embodiment, the modified shelf life of the beverage in the unsealed state is dynamically changed. The more the times of taking events of the beverage are, the longer the time of taking events of the beverage are, which indicates that the more the beverage is aggravated to be spoiled, the shorter the modified quality guarantee period of the beverage is, so that a user can be reminded of reasonably distributing the service cycle according to the modified quality guarantee period, and the actual expired beverage can be cleaned in time, thereby ensuring the freshness of the beverage stored in the refrigerator 1 by the user.

Further, the step of determining the remaining storage period of the beverage based on the occurrence period and the occurrence number of the pick-up event includes: accumulating the occurrence time h of the taking event; calculating a correction shelf life D ', wherein D' =D-h×k, k is a correction coefficient corresponding to the type of the beverage, and k is more than 1; the remaining storage period H of the beverage is determined from the modified shelf life D'.

In this embodiment, the occurrence time of the taking event is an accumulated value, for example, two taking events are currently detected, the occurrence time of the first taking event is 1 hour, the occurrence time of the second taking event is 2 hours, and the occurrence time of the current taking event is 2 hours. Considering that each occurrence of a pick-up event aggravates the spoilage process of the beverage, the determination of the modified shelf life D' based on the cumulative value of the time period of the pick-up event is relatively accurate.

k is a correction factor that is related to the type of beverage. The inventors realized that: different types of beverages have different spoilage rates in non-optimal storage environments, e.g., dairy products have greater spoilage rates than juice, and thus the introduction of a correction factor for each beverage allows for a more accurate corrected shelf life D'. Before the refrigerator 1 leaves the factory, a common beverage and its corresponding correction coefficients may be formed into a table and stored in the memory 44 so that the corresponding correction coefficients are queried when the corrected shelf life D' is calculated.

The correction factor k > 1, that is, the system considers that the actual consumed shelf life of the beverage is k times that of the optimal storage environment when the beverage is in the non-optimal storage environment, and the actual shelf life of the current beverage, namely the corrected shelf life D', is obtained by deducting the actual consumed shelf life of the non-optimal storage environment.

For example, the milk product has a shelf life of 45 days stored in a refrigerated environment at 2-6 ℃, the corresponding correction factor of 3, and the cumulative pick-up event occurs for 24 hours (1 day), at which time the current milk product has a corrected shelf life D' =45-1×3=42 days.

Further, the step of determining the remaining storage period H of the beverage based on the modified shelf life D' further comprises: judging whether the modified shelf life D' is larger than the use time length C, wherein the use time length C is the time length between the current time and the production date; if yes, the remaining storage duration of the beverage is h=d' -C; if not, the remaining storage period H of the beverage is zero.

When the modified shelf life D 'is greater than the use period C, indicating that the current beverage has time to continue to be stored, the remaining storage period of the beverage may be modified to h=d' -C. When the modified shelf life D' is less than or equal to the use duration C, the time that the current beverage is not stored continuously is indicated, the residual storage duration H of the beverage is zero, and the beverage is not fresh and needs to be treated in time.

Continuing with the above illustration, the corrected shelf life D' =45-1×3=42 days for the current dairy product is calculated. For another example, if the current time has been found to have elapsed 40 days from the date of manufacture, then the remaining shelf-life h=42-40=2 days of the dairy product, the shelf-life of the beverage obtained by this embodiment is 3 days earlier than the original shelf-life remaining shelf-life (the original shelf-life remaining shelf-life is 5 days further), to avoid the user from using a beverage that is within shelf-life but is not fresh. For another example, a query that the current time has elapsed 43 days from the date of manufacture indicates that the beverage has spoiled and has no value for storage and needs immediate disposal.

In some embodiments, the step of determining the remaining storage period of the beverage based on the occurrence of the pick-up event and the number of occurrences further comprises: recording the occurrence times of the taking events; inquiring preset times corresponding to the types of the drinks; judging whether the occurrence times of the taking events are larger than the preset times or not; and under the condition that whether the occurrence times of the taking events are larger than the preset times, the residual storage duration of the beverage is zero.

The inventors have also appreciated that: the factors affecting the taste of the beverage include temperature factors, the number of times of contact with air, and the like. For some beverages (e.g., carbonated beverages), the more frequent the exposure to air, the more air that enters the beverage, the more impact on mouthfeel. For such beverages, the beverage storage control method of the present embodiment determines the remaining storage period thereof by the number of occurrences of the take event.

Specifically, when the system obtains the type of the beverage and then inquires the corresponding preset times, and when the occurrence times of the taking events reach the preset times, the system considers that the beverage has no stored value and needs to be processed in time.

For example, for carbonated beverages, the corresponding preset number of times is 3, and when the 4 th taking event occurs, the system considers that the carbon dioxide in the carbonated beverage is completely consumed, the taste is extremely bad, and the carbonated beverage can be processed in time.

In some embodiments, the refrigerator 1 may further include a reminding device 60, and the reminding device 60 may be a buzzer, a light source, or the like. When the remaining storage duration of the beverage is zero, the buzzer can emit sound, and the light source can emit flashing light to remind a user of timely cleaning. The reminding mode of the buzzer and the reminding mode of the light source can be used alternatively or simultaneously, and the reminding mode of the light source can be determined according to actual conditions.

In some embodiments, the refrigerator 1 may further include a display panel 50 for displaying storage information and remaining storage time of the beverage so that a user detects a beverage state on the display panel 50.

In some embodiments, the step of identifying the storage status of the beverage may further comprise: detecting the actual weight of the beverage; judging whether the ratio of the actual weight of the beverage to the specification weight is in a preset ratio or not; if yes, judging that the beverage is in an unsealed state; if not, judging that the beverage is in an unsealed state.

The preset ratio is set to between 0.8 and 1, for example 0.8, 0.9 or 1, etc. When the ratio of the actual weight of the beverage to the specification weight is larger than the preset ratio, the actual weight of the beverage and the specification weight can be considered to be smaller, the beverage is considered to be not unsealed, namely in an unsealed state, and for the beverage in the unsealed state, the residual storage time can be normally determined according to the original quality guarantee period, the production date and the current date. When the ratio of the actual weight of the beverage to the specification weight is less than or equal to the preset ratio, the actual weight of the beverage and the specification weight can be considered to be greatly different, and the beverage is considered to be unsealed, namely in an unsealed state.

Referring to fig. 4, fig. 4 is a flowchart of a beverage storage control method according to another embodiment of the present invention. In some embodiments, the beverage storage control method of the refrigerator 1 may further include the following steps:

And when the judging result is that whether the beverage is in the unsealed state, executing step S405. After step S405, the following steps are performed:

step S406, judging whether a taking event occurs to the drink, wherein the taking event is an event that the drink is taken out of the refrigerator and then returned to the refrigerator.

If the determination result in step S406 is yes, step S407 is executed to accumulate the occurrence time h of the picking event.

In step S408, a modified shelf life D 'is calculated, where D' =d-h×k, and k is a modification coefficient corresponding to the type of beverage.

Step S409, judging whether the corrected shelf life D' is longer than the service life C. When the determination result is yes, step S410 is performed, and the remaining storage period of the beverage is h=d' -C. When the determination result is yes, step S414 is performed, where the remaining storage period of the beverage is zero.

If the determination result in step S406 is yes, step S411 is also executed simultaneously, and the number of times of the take event is recorded.

Step S412, inquiring the preset times corresponding to the types of the drinks.

Step S413, judging whether the occurrence times are larger than the preset times.

If the result of the determination in step S413 is yes, step S414 is executed, where the remaining storage period of the beverage is zero.

If the result of the determination in step S406 is negative, step S415 is executed to determine the remaining storage period based on the original shelf life, the date of production, and the current date.

Finally, step S416 is performed, and the determined remaining storage time period is output.
