Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
The terms "first," "second," and the like in the description and in the claims, and the above-described drawings of embodiments of the present disclosure, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the present disclosure described herein may be made. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.
Referring to fig. 1, an embodiment of the present disclosure provides a control method for a refrigerator, wherein the refrigerator includes a storage space; the control method comprises the following steps:
and S01, performing corresponding fresh-keeping processing according to the food information in the storage space.
S02, after the preservation treatment is finished, the information of the electronic tag of the storage space is updated; wherein the updated information includes a freshness date of the food.
By adopting the control method for the refrigerator provided by the embodiment of the disclosure, under the condition that food is stored in the storage space of the refrigerator, corresponding preservation processing is executed according to the detected food information, and then the electronic tag containing the food preservation period in the storage space is updated; the intelligent dynamic updating of the electronic tags in the storage space is realized, so that a user can call the information content of the electronic tags at any time, the freshness date of food in the storage space is known, and the food storage is facilitated.
Alternatively, the storage space may be plural. The term "plurality" means two or more unless otherwise specified.
The term "food" as used herein refers to uncooked food such as fruit, vegetable, meat, etc., and may also refer to directly edible cake or cooked food, and is not particularly limited herein. In addition, the above-mentioned control method may be used in a refrigerator, and in some cases, the article having a freshness requirement placed in the storage space of the refrigerator is not necessarily an edible article, for example, an article requiring refrigeration or freezing storage, such as ointment. At this moment, corresponding food information cannot be detected, and a user can manually set the preservation treatment which can be executed by the article placed in the storage space of the refrigerator according to the requirement and continue the steps after the preservation treatment is finished.
Generally, the freshness keeping process of a refrigerator includes a low temperature freshness keeping operation for increasing the freshness keeping period of food stored in a storage space by reducing the temperature of the storage space to inhibit the growth and reproduction of microorganisms in the storage space.
Optionally, the freshness treatment further comprises evacuating the storage space or filling the storage space with nitrogen gas. Therefore, the storage space is vacuumized or filled with nitrogen, so that food can be kept fresh better, and the food spoilage rate is slowed down.
Optionally, the storage space is subjected to vacuumized fresh-keeping treatment, the air in the storage space is partially or completely pumped out and kept in a sealed state to maintain a reduced pressure state in the storage space, and microorganisms in the food are in a low-pressure and anoxic state and lack the necessary conditions for survival and propagation to keep the food fresh, so that the purpose of slowing down food spoilage is achieved. For example, cooked food and dried fruit can be subjected to vacuum preservation treatment.
Optionally, the storage space is subjected to a nitrogen-filled fresh-keeping treatment by filling nitrogen into the storage space and sealing the storage space to prevent the food from contacting with oxygen during the storage process; the freshness keeping mode of filling nitrogen into the storage space can reduce the putrefaction rate of food by preventing the food from contacting with oxygen; the air pressure state in the storage space can not be changed, and the integrity of the food can be better ensured. For example, the cake and the leftovers can be treated by keeping fresh by filling nitrogen.
Optionally, if the food is fragile or perishable, evacuating the storage space; alternatively, if the food is fragile and perishable, the storage space is filled with nitrogen. Therefore, the food in the storage space can be subjected to proper fresh-keeping treatment operation according to different characteristics of the food, so that the fresh-keeping effect of the food can be guaranteed, the fresh-keeping period of the food can be prolonged, and the integrity of the food can be kept.
Alternatively, if the food is more fragile, the degree of vacuum is lower. Therefore, the food information can be acquired, the fragile condition of the food can be acquired in the database, and the food in the storage space can be subjected to the suitable fresh-keeping treatment operation according to different fragile conditions of the food, so that the food can be kept fresh while the fresh-keeping effect is ensured, the fresh-keeping period of the food is prolonged, and the integrity of the food is kept.
Optionally, a corresponding fresh-keeping process is performed according to the food information in the storage space: evacuating the storage space to a first vacuum level when food within the storage space is at a first frangible level; evacuating the storage space to a second vacuum level when the food within the storage space is at a second friable grade; wherein the first frangible rating is higher than the second frangible rating and the first vacuum level is less than the second vacuum level.
For example, the cake is put into the storage space, and through detection, the cake is in a high fragile grade and can be matched with a first fragile grade, so that the vacuumizing degree of the matched fresh-keeping treatment can be a lower vacuum degree, namely, the matched fresh-keeping treatment corresponds to the first vacuum degree, and thus, the fragile cake is stored in the lower vacuum degree, so that the integrity of the cake is not damaged.
For example, put into the nut to the storage space, detect that the food is the nut, through retrieving the breakable grade of nut in the data, the matching gets that the breakable grade of nut is lower, and here can match to the second breakable grade, then, the corresponding vacuum level is the second vacuum degree that is greater than first vacuum degree, like this, can prolong the fresh-keeping period of nut as far as possible.
Here, the classification of the friability grade into the first friability grade and the second friability grade, and the classification of the vacuum degree into the first vacuum degree and the second vacuum degree are not taken as limitations on the classification of the friability grade and the vacuum degree, but merely as a convenience in describing the correspondence of different friability grades and vacuum degrees. The first frangible rating and the second frangible rating can be any two different frangible ratings, and when the magnitude of the degree of frangibility of the first frangible rating and the second frangible rating is determined, the magnitude of frangibility can also be determined in relation to the degree of vacuum draw.
Alternatively, if the food is more perishable, the greater the degree of vacuum. Therefore, the perishable condition of the food can be acquired in the database through the acquired food information, and the food in the storage space can be subjected to proper fresh-keeping treatment operation according to different perishable conditions of the food, so that the fresh-keeping period of the food can be prolonged as much as possible.
Optionally, a corresponding fresh-keeping process is performed according to the food information in the storage space: evacuating the storage space at a third vacuum level when food in the storage space is at a first perishable level; evacuating the storage space at a fourth level of vacuum when food in the storage space is at a second perishable level; wherein the first perishable rating is higher than the second perishable rating and the third vacuum level is greater than the fourth vacuum level.
For example, cooked food is put into the storage space, and the food is obtained through detection as cooked food, and the matched perishable grade is high, namely the first perishable grade; then, the vacuum degree of the matched fresh-keeping treatment can be a higher vacuum degree, namely corresponding to a third vacuum degree, so that the fresh-keeping treatment of the putrescible cooked food with the higher third vacuum degree is adopted to prolong the fresh-keeping period of the cooked food as far as possible.
For example, put into cereal to the storage space, detect out that food is cereal, through the perishable grade of retrieving cereal in the data, it is lower to match the perishable degree that obtains cereal, and here can match for the second perishable grade, so, the fresh-keeping of corresponding vacuum degree is carried out to cereal less than fourth vacuum degree, like this, both can suitably prolong the fresh-keeping time limit of cereal, can also the energy saving.
Likewise, the first level of perishable spoilage and the second level of perishable spoilage are divided on the same principle as the aforementioned frangible rating. The third vacuum level and the fourth vacuum level are used to represent any two different vacuum levels, and the relationship between the vacuum level and the first vacuum level and the second vacuum level is not limited, and the third vacuum level may be the same as or different from the first vacuum level or the second vacuum level.
Alternatively, when the degree of vacuum pumping is different by matching the friable grade and the perishable grade, a nitrogen-filled preservation mode can be adopted as the fresh-keeping treatment for the food in the storage space. For example, detecting a high friability grade of pastry matches a low vacuum level, and since pastry matches a high perishable grade of pastry matches a high vacuum level, the freshness treatment is selected to be freshness preservation by nitrogen gas injection. Thus, the shelf life of the food can be prolonged as much as possible, and the integrity of the food can be ensured.
Optionally, the updated information further comprises the weight of the food. After the preservation treatment is finished, the weight of the food in the air and the weight of the food after the vacuumizing operation are changed, and the weight of the food is measured, so that the food information recorded by the updated electronic tag can be more perfect; and the intelligent dynamic update of the electronic tag in the storage space is realized, so that a user can call the information content of the electronic tag at any time, know the freshness date of food in the storage space and be beneficial to food preservation.
Optionally, the bottom of the storage space can be provided with a weighing device, when food is put into the storage space, the weight of the food can be obtained, and in the process of freshness keeping treatment, the food can be weighed in real time and fed back to the control device, so that the control device effectively controls the operation condition of the vacuumizing device on the storage space.
In some embodiments, the control method for a refrigerator further includes: and prompting the user of the freshness date of the food in the storage space according to the information recorded by the electronic tag. Therefore, under the condition that food is stored in the storage space of the refrigerator, corresponding fresh-keeping processing is executed according to the detected food information, and then the electronic tag containing the food fresh-keeping period in the storage space is updated; the intelligent dynamic updating of the electronic tag of the storage space is realized, and a user can intuitively obtain the information of food in the storage space and the remaining preservation period of the food so as to reasonably arrange an eating plan; the waste situation caused by the fact that the user forgets the food stored in the storage space is avoided.
Herein, the preservation period can be used to represent the longest storage period of the food which is not deteriorated, and can also be expressed by the storage period or the storage period, and the preservation period of different individuals of the same food is different, and similarly, the preservation period of an individual of the same food is different under different environmental parameters. Thus, by freshness date herein is meant the average of the different dates for other parameters not shown and for different individuals, except for the parameters explicitly indicated.
Optionally, after the refreshing process is completed, the execution result of the refreshing process can be detected; the execution result includes a freshness processing success or a freshness processing failure. For example, the vacuumizing device and other functional components do not have faults, the storage space is subjected to freshness keeping processing, the vacuumizing degree of the storage space matched by the control module according to the food information is reached, the freshness keeping processing of the specification is successful, and the updated information is written into the electronic tag. On the contrary, after the preservation processing is finished, the deviation between the vacuumizing degree in the storage space and the vacuumizing degree matched by the control module according to the food information is detected to be larger, so that the preservation processing system of the refrigerator breaks down, and a fault signal is transmitted to the control module without changing the content of the electronic tag.
Alternatively, the acquiring of the freshness keeping process condition in the storage space may be detecting a storage state of the food in the storage space, for example, detecting an air pressure in the storage space, detecting a weight of the food in the storage space, and detecting a ratio of other components in the storage space.
Optionally, before performing the freshness keeping process, the freshness keeping period of the food in the normal-temperature natural environment corresponding to the detected food information may be called from the database as an initial value of the food freshness keeping period of the electronic tag.
Optionally, after the preservation processing is completed, the corresponding relationship between the food information, the food storage state and the food preservation period can be obtained from the user historical data; and determining the food freshness date according to the corresponding relation, wherein the freshness date can be used as the updated freshness date stored in the electronic tag.
Alternatively, the food information may be obtained by obtaining a food image and determining the food information according to the correspondence between the food image and the food. For example, from an image of the food, the name and kind of the food, etc. are determined.
