Then, the cool air flows out again from the storage space 31, the first passage 43, and the second passage 44, and enters the refrigerating compartment 21 again.
Based on the foregoing description, those skilled in the art can understand that, by arranging the electromagnetic coil outside the storage space 31 and blowing the cold air provided by the refrigeration system 20, the cold air can timely take away the heat generated by the electromagnetic coil during operation, so that the heat generated by the electromagnetic coil is prevented from being conducted to the storage space 31, and the problem that the refrigeration and/or preservation of the food material is affected by the temperature of the storage space 31 due to the difficulty in cooling or temperature rise is prevented.
Further, by arranging the first electromagnetic coil 32 as the first main coil 321 and the first sub-coil 322 arranged side by side and arranging the second electromagnetic coil 33 as the second main coil 331 and the second sub-coil 332 arranged side by side, the refrigeration apparatus 100 can simultaneously energize the first main coil 321 and the second main coil 331, and the first sub-coil 322 and the second sub-coil 332 to generate a magnetic field when the food material in the storage space 31 is large, and only energize the first main coil 321 and the second main coil 331 to generate a magnetic field or energize the first sub-coil 322 and the second sub-coil 332 to generate a magnetic field when the food material in the storage space 31 is small, so that the energy consumption of the refrigeration apparatus 100 is reduced on the premise of ensuring the refrigeration, freezing and freshness preservation of the food material.
Fig. 5 is a schematic diagram of a cool air cycle of a refrigeration unit in accordance with further embodiments of the present invention.
In this further embodiment of the utility model, as shown in fig. 5, the refrigeration appliance 100 further comprises at least one partition 50 disposed within the storage compartment 40. The magnetic refreshing device 30 is clamped between the side wall of the storage cavity 40 and one of the partition plates 50, so that a third channel 45 is formed between the one partition plate 50 and the magnetic refreshing device 30, and a fourth channel 46 is formed between the side wall of the storage cavity 40 and the magnetic refreshing device 30. The first electromagnetic coil 32 is disposed in the third passage 45 and the second electromagnetic coil 33 is disposed in the fourth passage 46.
With continued reference to fig. 5, in the other embodiments of the present invention, the fourth channel 46 is communicated with the second air outlet 42, i.e. the second air outlet 42 corresponding to the second electromagnetic coil 33. In other words, the cool air supplied from the refrigeration system 20 cannot directly cool the second electromagnetic coil 33, but is cooled by the cool air returned to the refrigeration system 20.
Other features of the refrigeration device 100 according to other embodiments of the present invention are described in some of the embodiments above.
Fig. 6 is a schematic diagram of a cold draft cycle for a refrigeration unit in accordance with still other embodiments of the present invention.
As shown in fig. 6, in the further embodiments of the present invention, the refrigerating apparatus 100 includes at least two partitions 50 disposed in the storage compartment 40, and the magnetic refreshing apparatus 30 is disposed between two adjacent partitions 50, and thus a fifth passage 47 is formed between one of the two partitions 50 and the magnetic refreshing apparatus 30, and a sixth passage 48 is formed between the other of the two partitions 50 and the magnetic refreshing apparatus 30. The first solenoid coil 32 is disposed within the fifth passage 47 and the second solenoid coil 33 is disposed within the sixth passage 48.
Other features of the refrigeration device 100 according to other embodiments of the present invention are described in some of the embodiments above.
Furthermore, although not shown in the figures, in other embodiments of the present invention, the refrigeration device 100 further includes a permanent magnet corresponding to the electromagnetic coil. Specifically, one skilled in the art may configure a permanent magnet for at least one of the first main coil 321, the second main coil 331, the first sub-coil 322, and the second sub-coil 332 as needed.
So far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without departing from the technical principle of the present invention, a person skilled in the art may split and combine the technical solutions in the above embodiments, and may make equivalent changes or substitutions for related technical features, and any changes, equivalents, improvements, etc. made within the technical concept and/or technical principle of the present invention will fall within the protection scope of the present invention.
