Referring to fig. 1 and 2, the refrigerator of the present application includes a fresh keeping device 10, a vacuum pump 20, a pressure detecting device 30, and a controller 40.
The fresh-keeping device 10 is arranged in the refrigerator, and the fresh-keeping device 10 is used for providing a low-pressure storage environment for food materials.
The fresh-keeping device 10 has a safety pressure Ps and a system pressure P 0 And Ps > P 0 。
The vacuum pump 20 is connected with the fresh-keeping device 10 through a pipeline to vacuumize the fresh-keeping device 10, so that the internal pressure of the fresh-keeping device 10 reaches the low pressure required by food storage, and the fresh keeping of the food is improved.
The pressure detection device 30 is used to detect the pressure within the fresh food apparatus 10.
The controller 40 receives pressure data fed back from the pressure detecting means 30, and the controller 40 controls the operation of the vacuum 20 pump.
When the food is required to be stored/taken, the fresh-keeping device 10 is opened, after the time T1, the fresh-keeping device 10 is closed after the food is stored/taken, at the moment, the controller 40 controls the vacuum pump 20 to start vacuumizing the fresh-keeping device 10, in the process, the pressure detection device 30 detects the pressure in the fresh-keeping device 10 in real time and feeds back the detected pressure data to the controller 40, and when the pressure data reaches the safety pressure Ps, the controller 40 controls the vacuum pump 20 to stop.
The fresh-keeping device 10 then enters a low pressure holding stage, and as the external heat of the fresh-keeping device 10 is brought into the fresh-keeping device 10 when the fresh-keeping device 10 is opened, a temperature difference exists between the inside and the outside of the fresh-keeping device 10, and as time goes by, cold air in the refrigerator can gradually infiltrate into the fresh-keeping device 10, so that air in the fresh-keeping device 10 contracts, and the pressure in the fresh-keeping device 10 gradually decreases.
That is, although the pressure Ps reached by the fresh-keeping apparatus 10 at the time of the first evacuation after the closing is greater than the system pressure P 0 However, over time, the pressure within the preservation apparatus 10 gradually decreases until the system pressure P is reached 0 The low-pressure environment required by food material storage is satisfied.
If the fresh-keeping device 10 is vacuumized for the first time after being closed, the system pressure P is reached at a time 0 The pressure in the fresh-keeping device 10 is gradually reduced to be lower than the system pressure P with the lapse of time during the subsequent low-pressure maintaining process of the fresh-keeping device 10 0 Further, the structural strength of the fresh-keeping device 10 is damaged, and meanwhile, too fast water loss and freshness influence are caused by too large low pressure of partial food materials.
Therefore, the vacuumizing control mode in the application can meet the low-pressure environment required by food storage and does not influence the structural strength of the fresh-keeping device 10.
In some embodiments of the present application, after the preserving apparatus 10 is kept in the low pressure state T2 for a time in the following low pressure state maintaining process, the temperature inside and outside the preserving apparatus 10 tends to be consistent at this time, that is, the pressure change effect caused by the air shrinkage due to cooling in the preserving apparatus 10 disappears, the pressure in the preserving apparatus 10 tends to be stable, and the pressure detecting apparatus 30 starts to detect the pressure of the preserving apparatus 10 at this time.
If the pressure data detected by the pressure detecting device 30 reaches the system pressure P 0 At this time, it is indicated that the fresh-keeping device 10 meets the low-pressure storage requirement, and the controller 40 controls the vacuum pump 20 to stop continuously, so that the fresh-keeping device 10 does not need to be vacuumized.
If the pressure data detected by the pressure detecting means 30 is greater than the system pressure P 0 At this time, the pressure in the fresh-keeping device 10 does not meet the low-pressure storage requirement, and the controller 40 controls the vacuum pump 20 to vacuum the fresh-keeping device 10 to the system pressure P 0 And then stopped to allow the pressure within the preservation apparatus 10 to reach the low pressure storage requirement.
If the pressure data detected by the pressure detecting means 30 is smaller than the system pressure P 0 At this time, the controller 40 gives an alarm to release pressure from the fresh-keeping device 10, so as to prevent the fresh-keeping device 10 from being damaged due to too low pressure in the fresh-keeping device 10.
In some embodiments of the present application, the pressure detection device 30 is closed during the low pressure state of the preservation device 10; after the fresh-keeping apparatus 10 is kept in the low pressure state T2 for a while, the pressure detecting apparatus 30 starts to detect, and the pressure detecting apparatus 30 feeds back the detection data to the controller 40 and then turns off.
That is, the pressure detecting device 30 is not always in operation during the low pressure state of the fresh keeping device 10, so that the service life of the pressure detecting device 30 can be prolonged.
In some embodiments of the present application, the opening time T1 of the preservation apparatus 10 is in a proportional linear relationship with the safety pressure Ps.
That is, the longer the opening time T1 of the fresh-keeping apparatus 10, the more heat is introduced into the fresh-keeping apparatus 10 from the outside, the larger the temperature difference between the inside and the outside of the fresh-keeping apparatus 10, and the more obvious the pressure change caused by shrinkage of the chilled air is after the fresh-keeping apparatus 10 is closed, so the safety pressure Ps is correspondingly set to be relatively longer, and the structural reliability of the fresh-keeping apparatus 10 can be further ensured.
In practical applications, T1 may be set to a range, different T1 corresponds to a safety pressure Ps, the refrigerator is further configured with a time recorder for recording a single opening time of the fresh-keeping device 10, and the controller 40 controls the operation time of the vacuum pump 20 according to the opening time of the fresh-keeping device 10, so that the pressure in the fresh-keeping device 10 reaches the corresponding safety pressure Ps.
In some embodiments of the present application, the fresh food apparatus 10 is a fresh food drawer that is disposed within a fresh food compartment of a refrigerator.
In some embodiments of the present application, the preservation apparatus 10 is a preservation box, and the preservation box is disposed on a door of a refrigerator.
In the description of the above embodiments, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present application should be included in the scope of the present application. Therefore, the protection scope of the application is subject to the protection scope of the claims.
