The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The refrigerator can be divided into a refrigerator, a hall bar, and the like. The freezer structure that this application provided can be applicable to in any type of freezer.
Wherein the freezer generally includes a compressor, a condenser, and an evaporator. The compressor compresses a refrigerant gas in a high-temperature and high-pressure state, and discharges the compressed refrigerant vapor. The refrigerant vapor is adiabatically compressed by the compressor and then changed into high-temperature and high-pressure vapor, and the vapor enters the condenser. The condenser condenses the refrigerant vapor, changes the vapor to a low-temperature liquid refrigerant, and dissipates heat to the surrounding medium. The refrigerant of high pressure and low temperature is throttled and converted into refrigerant vapor of low temperature and low pressure, and enters the evaporator. The evaporator evaporates the refrigerant, absorbs heat of the surrounding medium, and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator achieves a cooling effect by heat exchange with a material to be cooled using latent heat of evaporation of a refrigerant.
As shown in fig. 1 to 6, a refrigerator of a preferred embodiment of the present invention includes a cabinet 1, the cabinet 1 having a refrigerating chamber 2.
In order to realize the vacuum preservation of food materials, the refrigerator further comprises a vacuum box 3 and a vacuum-pumping system 6.
Wherein, vacuum box 3 detachably connects in walk-in 2, is equipped with the chamber that holds that is used for depositing edible material in the vacuum box 3, has seted up extraction opening 4 on the vacuum box 3.
An evacuation system 6 is installed within the refrigerated compartment 2, the evacuation system 6 comprising a vacuum pump assembly 61, a controller 63, and a vacuum connection 62, wherein, in some embodiments, the vacuum pump assembly 61 comprises a vacuum pump.
The vacuum pump assembly 61 is connected to a vacuum connection 62. The controller 63 is electrically connected to the vacuum pump assembly 61, and the controller 63 is used for controlling whether the vacuum pump assembly 61 starts the vacuum pumping operation.
The vacuum connector 62 is detachably connected to the pumping port 4, and when the vacuum box 3 is pumped to be evacuated, the pumping port 4 is connected to the vacuum connector 62, and the controller 63 controls the vacuum pump assembly 61 to pump the vacuum to the vacuum box 3. When the vacuum box 3 needs to be taken out, the suction port 4 is separated from the vacuum connector 62.

The magnet 5 is installed at a position of the vacuum box 3 near the suction opening 4, and the magnetic induction member 7 is installed at a position of the refrigerating compartment 2 near the vacuum connector 62 and electrically connected to the controller 63.
Under operating condition, vacuum box 3 is located walk-in 2, and when extraction opening 4 and vacuum joint 62 were connected, magnet 5 that sets up on vacuum box 3 got into the response scope of magnetic induction component 7, and magnetic induction component 7 senses magnet 5 to feed back the signal to controller 63, controller 63 control vacuum pump subassembly 61 carries out the evacuation operation to vacuum box 3.
When the vacuum box 3 is taken out, the air suction port 4 is separated from the vacuum connector 62, the magnet 5 gradually gets away from the sensing area of the magnetic sensing element 7, the magnetic sensing element 7 feeds back a signal to the controller 63, and the controller 63 controls the vacuum pump assembly 61 to stop vacuumizing.
In some embodiments, the magnetic sensing element 7 is a magnetic sensitive switch capable of sensing the magnetic field of the magnet 5 and feeding back a signal to the controller 63. For example, the magnetically sensitive switch may be the switch disclosed under publication number CN 202978873U.
In other embodiments, the magnetic induction element 7 may also be other magnetic components.
The induction distance of the magnetic induction element 7 is 0-20 mm, the induction range is small, the situation that the extraction opening 4 is not connected with the vacuum connector 62 is avoided, and the magnetic induction element 7 starts the vacuum pump assembly 61 to vacuumize the vacuum box 3.

The vacuum pumping system 6 further comprises a sealing ring 65, the outer ring of the sealing ring 65 is connected with the inner wall of the limiting concave part 8, and the inner ring of the sealing ring 65 is connected with the periphery of the vacuum joint 62. The sealing ring 65 is arranged to ensure the sealing connection between the vacuum joint 62 and the vacuum joint seat 64, so as to prevent the vacuum box 3 from being in a vacuum state due to the gap generated between the vacuum joint 62 and the vacuum joint seat 64.
In addition, the refrigerator provided by the application also comprises a shelf 10, the shelf 10 is installed in the refrigerating chamber 2, and the vacuum box 3 is detachably connected to the upper surface of the shelf 10. A shelf 10 is provided in the refrigerating compartment 2 for carrying the vacuum boxes 3 and providing support for the vacuum boxes 3.
In some embodiments, two limiting plates 11 are disposed on the upper surface of the shelf 10, and a limiting channel for the vacuum box 3 to pass through is left between the limiting plates 11. A limiting plate 11 is arranged on the shelf 10, which can further limit the relative position of the suction opening 4 in the vacuum box 3 and the vacuum connector 62, and the vacuum box 3 can slide in the limiting channel, so that a user can align the suction opening 4 on the vacuum box 3 with the vacuum connector 62.
In other embodiments, the shelf 10 may not have the limiting plate 11, and is not limited to the above examples.

The user puts into the freezer with vacuum box 3, and vacuum box 3 slides along the length direction of spacing passageway, and the one side that is equipped with extraction opening 4 on vacuum box 3 is close to vacuum connector seat 64. When the suction port 4 on the vacuum cassette 3 is butted against the vacuum joint 62 on the vacuum joint base 64, the positioning projection 9 is inserted into the stopper recess 8. At this time, the magnet 5 is in the sensing range of the magnetic sensing element 7, the magnetic sensing element 7 inputs a signal to the controller 63, and the controller 63 determines that the air suction port 4 is accurately connected to the vacuum connector 62, and controls the vacuum pump assembly 61 to start to vacuumize the vacuum box 3. As can be seen from fig. 6, the vacuum box 3 does not need to be in contact with the magnetic induction element 7, and only the magnet 5 needs to be ensured to enter the induction range of the magnetic induction element 7. When the user takes out the vacuum box 3 from the refrigerator, the positioning protrusion 9 is disengaged from the limiting concave portion 8, and the magnet 5 is far away from the magnetic induction element 7 and is not in the detection range of the magnetic induction element 7.
