In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.
The refrigerator may be classified into a refrigerator, a cafe, etc. The refrigerator structure provided by the application can be suitable for any type of refrigerator.
Wherein the refrigerator generally includes a compressor, a condenser, and an evaporator. The compressor compresses refrigerant gas in a high-temperature and high-pressure state and discharges compressed refrigerant vapor. The refrigerant vapor is compressed adiabatically by the compressor and then becomes high-temperature and high-pressure vapor, which enters the condenser. The condenser condenses the refrigerant vapor, changing the vapor into a low temperature liquid refrigerant, while dissipating heat to the surrounding medium. The high-pressure low-temperature refrigerant is throttled and then converted into low-temperature low-pressure refrigerant vapor, 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 refrigerating effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant.
As shown in fig. 1 to 6, a refrigerator according to a preferred embodiment of the present invention includes a cabinet 1, the cabinet 1 having a refrigerating compartment 2.
In order to realize vacuum preservation of food materials, the refrigerator further comprises a vacuum box 3 and a vacuumizing system 6.
Wherein, vacuum box 3 detachably connects in refrigerating chamber 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.
A vacuum evacuation system 6 is mounted within the refrigerated compartment 2, the vacuum 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 connector 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 is turned on for vacuum pumping operation.
The vacuum connector 62 is detachably connected to the pumping port 4, and when the vacuum box 3 is pumped down, the pumping port 4 is connected to the vacuum connector 62, and the controller 63 controls the vacuum pump assembly 61 to pump down the vacuum box 3. When the vacuum box 3 needs to be taken out, the pumping port 4 is separated from the vacuum connector 62.
The ice bin further comprises a magnet 5 and a magnetic induction element 7. The magnet 5 is installed at a position of the vacuum box 3 near the air extraction opening 4, and the magnetic induction element 7 is installed at a position of the refrigerating chamber 2 near the vacuum connector 62 and is electrically connected with the controller 63.
Under the operating condition, the vacuum box 3 is positioned in the refrigerating chamber 2, when the air extraction opening 4 is connected with the vacuum connector 62, the magnet 5 arranged on the vacuum box 3 enters the induction range of the magnetic induction element 7, the magnetic induction element 7 senses the magnet 5 and feeds back signals to the controller 63, and the controller 63 controls the vacuum pump assembly 61 to carry out vacuumizing operation on the vacuum box 3.
When the vacuum box 3 is taken out, the air extraction opening 4 is separated from the vacuum connector 62, the magnet 5 is gradually far away from the induction area of the magnetic induction element 7, the magnetic induction 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 magnetically sensitive element 7 is a magnetically 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 a switch with publication number CN 202978873U.
In other embodiments, the magnetic inductive element 7 may also be other magnetic components.
The sensing distance of the magnetic sensing element 7 is 0 mm-20 mm, the sensing range is small, and the situation that the air extraction opening 4 is not connected with the vacuum connector 62 and the vacuum pump assembly 61 is started to vacuumize the vacuum box 3 by the magnetic sensing element 7 is avoided.
In some embodiments, the magnet 5 is a magnetic core, having a relatively high magnetic flux density and high magnetic permeability, and also having low loss characteristics.
In other embodiments, magnetic induction switches may also be employed instead of the magnetic cores and magnetically sensitive switches, not limited to the examples described above.
As shown in fig. 6, the magnet 5 is fixedly attached to the inner wall of the vacuum box 3. If the magnet 5 is attached to the outer wall of the vacuum box 3, the magnet 5 is easily dropped and lost when the vacuum box 3 is easily collided with other objects, resulting in the failure of the entire vacuum pumping system 6.
In actual use, the magnet 5 does not need to be in direct contact with the magnetically sensitive switch, and only needs to ensure that the magnet 5 enters the induction range of the magnetically sensitive switch when the air extraction opening 4 is in butt joint with the vacuum connector 62.
Therefore, when the suction port 4 is connected to the vacuum joint 62, the distance between the magnetic induction element 7 and the magnet 5 is 15mm to 20mm.15mm is the wall thickness of the vacuum box 3 reserved. If the distance between the magnetic sensing element 7 and the magnet 5 is greater than 20mm when the suction port 4 is in butt joint with the vacuum connector 62, the magnet 5 exceeds the sensing range of the magnetic sensing element 7, the magnetic sensing element 7 cannot detect the magnet 5, and the vacuum pump assembly 61 cannot perform vacuum pumping operation.
The vacuumizing system 6 further comprises a vacuum connector 64, the vacuum connector 64 is arranged in the refrigerating chamber 2, and the vacuum connector 62 and the magnetic induction element 7 are arranged on the vacuum connector 64, so that the vacuum connector 62 and the magnetic induction element 7 are connected and fastened with the refrigerating chamber 2.
The vacuum joint seat 64 is provided with a limit concave part 8, and the limit concave part 8 is arranged around the vacuum joint 62; the vacuum box 3 is provided with a positioning bulge 9, and the positioning bulge 9 surrounds the periphery of the air extraction opening 4 and is matched with the limit concave part 8 in a positioning way; when the air extraction opening 4 is connected with the vacuum connector 62, the positioning protrusion 9 is inserted into the limit concave part 8 to limit the relative position of the air extraction opening 4 and the vacuum connector 62 on the vacuum box 3, so that the connection accuracy of the vacuum connector 62 and the air extraction opening 4 in the specific induction range of the magnetic induction element 7 is ensured, and the situation that the magnet 5 enters the detection range of the magnetic induction element 7 but the air extraction opening 4 and the vacuum connector 62 are dislocated is avoided.
The vacuumizing system 6 further comprises a sealing ring 65, the outer ring of the sealing ring 65 is connected with the inner wall of the limit concave part 8, and the inner ring of the sealing ring 65 is connected with the periphery of the vacuum connector 62. By arranging the sealing ring 65, the sealing connection between the vacuum connector 62 and the vacuum connector seat 64 is ensured, and a gap is prevented from being generated between the vacuum connector 62 and the vacuum connector seat 64, so that the vacuum box 3 cannot be in a vacuum state.
The magnetic induction element 7 is connected to the side of the vacuum connector seat 64 facing away from the vacuum box 3, so that the magnetic induction element 7 and the vacuum pump assembly 61 are both positioned on the same side of the vacuum box 3, and the wire connection between the magnetic induction element 7 and the vacuum pump assembly 61 is convenient.
In addition, the refrigerator provided by the application further comprises a shelf 10, the shelf 10 is arranged 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 box 3, providing support for the vacuum box 3.
In some embodiments, two limiting plates 11 are arranged on the upper surface of the shelf 10, and a limiting channel for the vacuum box 3 to pass through is reserved between the limiting plates 11. The shelf 10 is provided with the limiting plate 11, so that the relative position of the extraction opening 4 in the vacuum box 3 and the vacuum connector 62 can be further limited, and the vacuum box 3 can slide in the limiting channel, so that a user can align the extraction opening 4 in the vacuum box 3 with the vacuum connector 62.
In other embodiments, the shelf 10 may not be provided with a limiting plate 11, which is not limited to the above example.
The working principle of the invention is as follows: the vacuum pumping system 6 is installed in the refrigerating chamber 2, the magnetic induction element 7 is installed in the refrigerating chamber 2, and a magnetic field within an induction range of the magnetic induction element 7 can be detected. A magnet 5 is mounted in the vacuum box 3. The user puts vacuum box 3 into the freezer, and vacuum box 3 slides along the length direction of spacing passageway, and the side that is equipped with extraction opening 4 on the vacuum box 3 is close to vacuum nipple seat 64. When the suction port 4 on the vacuum box 3 is docked to the vacuum joint 62 on the vacuum joint seat 64, the positioning boss 9 is inserted into the limit 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 pumping port 4 is accurately docked to the vacuum connector 62, and controls the vacuum pump assembly 61 to start, so as to pump the vacuum box 3. As can be seen from fig. 6, the vacuum box 3 need not be in contact with the magnetic inductive element 7, but need only ensure that the magnet 5 enters the inductive range of the magnetic inductive element 7. When the user removes the vacuum box 3 from the refrigerator, the positioning protrusion 9 is disengaged from the limit recess 8, and the magnet 5 is away from the magnetic sensing element 7 and is not within the detection range of the magnetic sensing element 7. The magnetically sensitive element 7 feeds back a signal to the control system which controls the vacuum pump assembly 61 to stop the evacuation.
