Fig. 1 is a schematic perspective view of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 of the present embodiment may generally include a cabinet 120, a door 110, and a refrigeration system (not shown in the drawings). The housing 120 may define at least one storage compartment, typically a plurality of storage compartments, with an open front side, such as a refrigerated storage compartment, a frozen storage compartment, a temperature-variable storage compartment, and the like. The number and function of the specific storage compartments can be configured according to pre-determined requirements. The refrigerator 10 of this embodiment should at least have a freezing compartment or a temperature-variable compartment (i.e., a compartment that can be used to achieve a freezing storage environment) with a temperature that can reach the freezing range. The temperature range of the frozen stock may be generally set to-14 ℃ to-22 ℃.
The refrigerator 10 of the present embodiment may be an air-cooled refrigerator, and an air path system is disposed in the cabinet 120, and a fan is used to send the cooling air that has exchanged heat with the heat exchanger to the storage compartment through the air supply opening, and then return the cooling air to the air duct through the air return opening. And refrigeration is realized. Since the refrigerator body 120, the door 110, and the refrigeration system themselves are well known and easily implemented by those skilled in the art, the details of the refrigerator body 120, the door 110, and the refrigeration system themselves are not described below in order to avoid covering and obscuring the invention points of the present application.
A freezing storage assembly 200 is arranged in the freezing storage chamber. The frozen storage assembly 200 forms an independent and closed frozen storage space, which can improve the storage quality of the frozen storage space by means of a magnetic field. Under the action of a magnetic field with certain strength, the free path of water molecules can be limited in the freezing process, and hydrogen bonds in the water molecule clusters are broken. Because the growth of crystal nucleus is inhibited, the growth rate of ice crystal is higher than the migration rate of water molecules, the generated ice crystal is smaller, thereby causing less damage to cells, reducing the loss rate of juice and preserving the nutrition and taste of food materials better. In addition, the magnetic field can shorten the freezing time and help to inhibit the number of microorganisms and bacteria.
Fig. 2 is a schematic view of a refrigerated storage assembly 200 of the refrigerator 10 according to one embodiment of the present invention. The frozen storage assembly 200 may include: magnetic conduction frame 210, solenoid 230, storing box.
Fig. 3 is a schematic view of a magnetically conductive outer frame 210 in the frozen storage assembly 200 of the refrigerator 10 according to an embodiment of the present invention. The magnetic conductive outer frame 210 is made of a magnetic material, and bosses 220 are formed on opposite inner walls thereof, respectively. The magnetic material may be soft magnetic material or hard magnetic material, for example, soft magnetic material may be used, the soft magnetic material is characterized by having low coercive force and high magnetic permeability, and the magnetic conductive outer frame 210 may be used to gather the magnetic field, prevent the magnetic field from releasing to the outer wall of the frozen storage assembly 200, and prevent interference (e.g., magnetic attraction, etc.) to other components outside the frozen storage assembly 200.
The magnetic conductive outer frame 210 can be a frame body in a shape of a square, i.e. a square cylinder. The front end and the rear end of the square frame body are respectively provided with a through opening. As shown in fig. 3, in some embodiments, the bosses 220 may be formed on the inside of the top and bottom walls of the frame in a square shape. In other embodiments, the bosses 220 are formed on the inner sides of the two side walls of the frame body. In view of the structure of the freezing storage compartment, the upper and lower longitudinal dimensions of which are smaller than the left and right transverse dimensions, and the dimensions of the top and bottom walls of which are larger, to facilitate the arrangement of the electromagnetic coil 230, it is preferable that the present embodiment forms the bosses 220 on the inner sides of the top and bottom walls of the frame body in a shape of a square. The cross-section of the boss 220 may be square, circular or elliptical, and when a square cross-section is used, the boss 220 is more easily matched with the structure of the case 120. The inner circumference of the solenoid coil 230 is shaped to fit the outer circumference of the boss 220 and is correspondingly square, circular or elliptical.
Two sets of electromagnetic coils 230 are respectively sleeved on one boss 220 and configured to generate a magnetic field after being electrified, and magnetic lines of force of the magnetic field penetrate through the internal space of the magnetic conductive outer frame 210 and then complete a closed loop through the magnetic conductive outer frame 210.
Fig. 4 is a schematic view of the electromagnetic coil 230 in the frozen storage assembly 200 of the refrigerator 10 according to an embodiment of the present invention. The electromagnetic coil 230 may be formed in a flat box shape and wound in a circumferential direction such that a magnetic pole direction of a magnetic field generated after the electromagnetic coil 230 is energized is perpendicular to the boss 220. In other embodiments, solenoid 230 may be configured as a flat, elliptical ring or ring.
The height of the boss 220 may be adapted to the thickness of the solenoid coil 230, so that the inner wall of the frame body in the shape of a square with the solenoid coil 230 is substantially flush, so as to arrange the storage box.
In order to ensure uniform magnetic field intensity, the present embodiment adopts two sets of electromagnetic coils 230 arranged oppositely. The two sets of electromagnetic coils 230 may be mirror images of each other and the magnetic pole directions of the generated magnetic fields are arranged to be the same. Fig. 5 and 6 are schematic views of a magnetic field formed in the freezing storage assembly 200 of the refrigerator 10 according to an embodiment of the present invention, respectively, in which the drawer 242 is hidden to show an internal structure. The magnetic poles are also oriented so that the magnetic lines of force are oriented in the same direction. In some embodiments, the two sets of electromagnetic coils 230 can change the direction of the magnetic poles by adjusting the direction of the applied current, but the two sets of electromagnetic coils 230 are switched simultaneously to form a magnetic field similar to that of fig. 5 or 6. The magnetic lines of force of the magnetic field penetrate through the internal space of the magnetic conductive outer frame 210 and then complete a closed loop through the magnetic conductive outer frame 210, so that the magnetic field is distributed unevenly or affects the external components of the frozen storage assembly 200.
The magnetic conductive outer frame 210 is used for guiding the magnetic field generated by the electromagnetic coil 230, so as to avoid the uneven magnetic field and other parts affecting the outside of the frozen storage assembly 200, and enable the electromagnetic coil 230 to form a magnetic field with uniform strength enough to meet the requirement of improving the quality of frozen storage in the frozen storage space. Further, the magnetic conduction outer frame 210 also provides an assembly structure for the electromagnetic coil 230, and reduces the occupied space, thereby improving the practicability.
The storage box is installed in the inner space of the magnetic conduction outer frame 210 and is used for forming a frozen storage space, so that the frozen storage space is in the magnetic field range. The storage box can form an independent and sealed freezing storage space, so that a better freezing storage environment is provided by special food materials.
The storage box may include: a tub 241 and a drawer 242. The outer cylinder 241 is disposed in the magnetic conductive outer frame 210 and has a forward opening. The drawer 242 is drawably provided in the outer tub 241. The front panel of the drawer 242 may form a sealing structure with the outer tub 241. When the refrigerator 10 uses air cooling to cool, an air inlet 243 and an air return 244 are formed in the rear wall of the outer cylinder 241, the air inlet 243 is used for connecting an air duct air supply outlet of the refrigerator 10 or communicating with an evaporator of the refrigerator 10 (for example, communicating with the top area of the evaporator) so as to introduce a cooling air flow into the storage box; the return air inlet 244 is adapted to be coupled to a duct return air inlet of the refrigerator 10 or to an evaporator of the refrigerator 10 (e.g., to a bottom region of the evaporator) to return a heat exchanged air stream to the return air duct or evaporator of the refrigerator 10. In some embodiments, the intake opening 243 and the return opening 244 may be provided with dampers (not shown). The air door is controlled to be opened when cooling air supply is carried out. The air inlet 243 and the air return 244 may be configured according to the position and structure of the air duct and the evaporator of the air-cooled refrigerator, and in other embodiments, the air return 244 may also be disposed on the sidewall of the outer tub 241.
The freezing storing assembly 200 of this embodiment can also combine together the magnetic field control of solenoid 230 with refrigeration control, guarantees that food freezes in the magnetic field environment, realizes fresh-keeping frozen effect. Fig. 7 is a block diagram of a control system of the refrigerator 10 according to an embodiment of the present invention, and the refrigerator 10 is further provided with a storage temperature sensor 250, a coil temperature sensor 260, a drawer opening/closing detector 270, and a controller 300.
The storage temperature sensor 250 is provided in the outer tube 241 of the storage box and detects the temperature in the drawer 242. A coil temperature sensor 260 is disposed adjacent to the location of the electromagnetic coil 230 and is used to detect the temperature at the electromagnetic coil 230, and in some embodiments the coil temperature sensor 260 may be disposed at the electromagnetic coil 230 at the bottom of the drawer 242. The drawer opening/closing detector 270 is configured to detect an open/closed state of the drawer 242.
When the electromagnetic coil 230 generates a magnetic field, heat is generated to some extent. Therefore, in order to avoid the heat of the solenoid coil 230 from affecting the cooling, the solenoid coil 230 is further configured to de-energize when the temperature detected by the coil temperature sensor 260 exceeds a preset protection temperature, thereby achieving the overheat protection.
Drawer opening/closing detector 270 is configured to detect the open/close state of drawer 242. After the drawer 242 is pulled open and then closed, it is possible to detect whether a new food material is put in or whether an original food material needs to be re-frozen by means of the storage temperature sensor 250. Then, the electromagnetic coil 230 is matched with a refrigerating system, so that magnetic field-assisted freezing can be realized, and the freezing and fresh-keeping effects of food materials are improved.
The controller 300 includes a memory 310 and a processor 320. A control program 311 is stored in the memory 310, and when executed by the processor 320, the control program 311 controls the solenoid 230 and the refrigeration system. Various sensors provide detection means for magnetic field control, so that the control requirements of corresponding control methods can be met.

step S802, determining that the storage box is opened and then closed, namely judging whether an opening and closing event occurs to the storage box;
step S804, obtaining the internal temperature change of the storage box before being opened and after being closed;
step S806, determine whether the amplitude of the internal temperature change is greater than a first set threshold, that is, determine whether a new food is put into the storage box, or whether the temperature of the food has risen and needs to be frozen again, where the first set threshold may be set to 2-8 ℃. If the change amplitude of the internal temperature is small, the food does not need to be frozen again, the conventional refrigeration control of freezing storage can be performed, namely, the refrigeration control is performed according to the set starting temperature threshold and the set shutdown temperature threshold.
Step S808, start cooling, supply air to the frozen storage assembly 200, and simultaneously energize the electromagnetic coil 230 to generate a magnetic field in the storage box, and assist in freezing by the magnetic field.
In step S810, it is determined whether the temperature of the solenoid coil 230 exceeds a predetermined temperature, that is, whether the temperature of the solenoid coil 230 affects normal cooling. The basis for determining the overrun may include: the temperature at the solenoid coil 230 exceeds a preset temperature protection value (e.g., -2 to 0 degrees celsius).
In step S812, the energization of the electromagnetic coil 230 is stopped.
Step S820, determine whether the internal temperature of the storage box is lower than the second threshold value, that is, determine whether the freezing stage is completed.
Step S822, determining whether the internal temperature of the storage box is lower than a refrigeration shutdown point temperature, where the refrigeration shutdown point temperature may be set according to a freezing set temperature, for example, 2 to 4 degrees lower than the freezing set temperature.
Step S824, stop supplying air to the frozen storage assembly 200, and resume the conventional refrigeration control of the frozen storage. The whole magnetic field assisted freezing process is completed through the steps.
