[0083] Please refer to Figures 1 to 3 The refrigerator of the preferred embodiment of the present application comprises: a box body 100, a storage assembly 200, and a magnetic field generating assembly 300.

[0084] The box body 100 comprises an outer shell 110 and a tank 120 arranged inside the outer shell 110; an installation space is formed between the outer shell 110 and the tank 120 for mounting other components and structures of the refrigerator and forming a foamed insulation layer. The inside of the tank 120 forms a refrigeration chamber 121, that is, a refrigeration chamber, a variable temperature chamber or a freezing chamber, which can be used to place the storage assembly 200 and the magnetic field generating assembly 300, so as to store food and preserve the food.

[0085] The refrigerator has a refrigeration cycle system for cooling the tank 120, which generally includes components such as a compressor, a condenser, a dry filter, a capillary tube, and an evaporator connected by the refrigeration cycle pipeline. The working structure of the refrigeration cycle system includes compression process, condensation process, throttling process, and evaporation process. Specifically, the compression process is as follows: after the refrigerator power cord is plugged in and the temperature controller contacts are connected, the compressor starts to work, the low-temperature, low-pressure refrigerant from the evaporator is sucked into the compressor, compressed into high-temperature, high-pressure superheated gas in the compressor cylinder, and then discharged into the condenser. The condensation process is as follows: the high-temperature, high-pressure refrigerant gas is cooled by the condenser, the temperature continuously decreases, and gradually cools into a normal-temperature, high-pressure saturated vapor, and further cools into a saturated liquid, the temperature no longer decreases, and the pressure of the refrigerant in the entire condensation process is almost unchanged. The throttling process is as follows: the condensed refrigerant saturated liquid flows into the capillary tube after filtering out water and impurities by the dry filter, and is throttled and depressurized by the capillary tube, and the refrigerant becomes a normal-temperature, low-pressure wet vapor. The evaporation process is as follows: the normal-temperature, low-pressure wet vapor enters the evaporator, starts to absorb heat and vaporizes, lowers the temperature of the evaporator and its surroundings, and makes the refrigeration chamber 121 achieve refrigeration, and the refrigerant becomes a low-temperature, low-pressure gas. The refrigerant from the evaporator returns to the compressor again, and the above process is repeated to convert energy through the state change of the refrigerant, transfer the heat in the refrigerator to the air outside the tank, and thus achieve the refrigeration cycle of the refrigerator. When the evaporator is arranged on the cavity wall of the refrigeration chamber 121, it is a direct-cooling refrigerator; when the evaporator is arranged in the air duct of the refrigerator, it is a forced-air-cooling refrigerator. The structure and operation principle of the above-mentioned refrigerator refrigeration cycle system are all prior art, and will not be described in detail in this application.

[0086] The refrigeration cycle pipeline is arranged on the outer wall of the tank 120, and the refrigeration cycle pipeline can directly exchange heat with the tank 120 through internal cold air circulation, thereby cooling the refrigeration chamber 121 in the tank 120, and thereby cooling the magnetic field generating assembly 300 and the storage assembly 200.

[0087] Referring to Figures 1 to 3 The storage assembly 200 is arranged in the refrigeration chamber 121 and can be located in the refrigeration chamber, the variable-temperature chamber, or the freezing chamber. In this embodiment, the storage assembly 200 is a drawer having a food storage space, and the inner wall of the tank 120 is provided with a slide rail in sliding connection with the drawer, so that the drawer can be pulled in and out in the refrigeration chamber 121 for the user to put in or take out food.

[0088] Referring to Figures 1 to 3The magnetic field generating assembly 300 is arranged in the refrigeration chamber 121, and the magnetic field generating assembly 300 is located in the same refrigeration chamber 121 as the storage assembly 200, that is, the magnetic field generating assembly 300 needs to be placed in the refrigeration chamber 121 corresponding to the storage assembly 200, so that the magnetic field generating assembly 300 provides a magnetic field for the food in the storage assembly 200.

[0089] With reference to Figure 3 and Figure 4 The magnetic field generating assembly 300 includes a fixing frame 310 and a coil 320. The fixing frame 310 is located on one side of the storage assembly 200, and the coil 320 is arranged on the fixing frame 310 and used to generate a magnetic field in the storage space of the storage assembly 200, so as to generate a magnetic field for food preservation. The fixing frame 310 is used to fix the coil 320, so that the magnetic field generated by the coil 320 can pass through the storage space of the storage assembly 200 and provide a basis for food preservation. The coil 320 can be connected to the power supply of the refrigerator through a wire, and the coil 320 can generate a magnetic field after being powered on.

[0090] With reference to Figure 3 and Figure 4 The fixing frame 310 includes a fixing structure 311 and a heat insulation plate 312. The fixing structure 311 has a containing cavity 3111, and the coil 320 is located in the containing cavity 3111. The containing cavity 3111 can accommodate the entire coil 320, so that the coil 320 does not exceed the containing cavity 3111, avoiding the contact between the coil 320 and condensed water, which causes the coil 320 to be short-circuited. The heat insulation plate 312 is located between the coil 320 and the storage assembly 200, so as to cut off the heat transfer route between the coil 320 and the storage assembly 200, preventing the heat generated by the coil 320 during work from being transmitted to the storage assembly 200 through the space between the coil 320 and the storage assembly 200.

[0091] Therefore, the refrigerator of the embodiment sets the heat insulation plate 312 between the coil 320 and the storage assembly 200, so as to cut off the heat transfer route between the coil 320 and the storage assembly 200, preventing the heat generated by the coil 320 during work from being transmitted to the storage assembly 200 through the space between the coil 320 and the storage assembly 200. The heat generated by the coil 320 during work cannot be transmitted to the storage assembly 200, avoiding the temperature rise of the food in the storage assembly 200 due to the heat of the coil 320, so that the food in the storage assembly 200 is preserved according to the expected magnetic field, and the food preservation effect of the refrigerator is ensured.

[0092] It should be noted that the magnetic field generating assembly 300 can be arranged at the upper side, lower side, left side, right side, front side, rear side, etc. of the storage assembly 200, and can be arranged according to the actual space of the refrigeration cavity 121 in the refrigerator, so as to ensure that the magnetic field generated by the magnetic field generating assembly 300 can act on the food in the storage assembly 200, thereby ensuring the food preservation effect of the refrigerator.

[0093] In some embodiments, with reference to Figure 1 and Figure 5 , the magnetic field generating assembly 300 is located at the lower side of the storage assembly 200, and the heat insulation plate 312 is located above the coil 320. The heat insulation plate 312 can prevent the heat generated by the coil 320 from being transmitted upward to the storage assembly 200 from the lower side, thereby avoiding the temperature of the food in the storage assembly 200 from rising due to the heat of the coil 320, so that the food in the storage assembly 200 is preserved by the magnetic field as expected, and the food preservation effect of the refrigerator is ensured.

[0094] In some embodiments, with reference to Figure 4 , Figure 5 and Figure 10 , the fixing structure 311 comprises a first opening 3112; the first opening 3112 is located at the side of the fixing structure 311 facing the storage assembly 200, and the first opening 3112 is in communication with the accommodating cavity 3111; the heat insulation plate 312 is located at the side of the fixing structure 311 facing the storage assembly 200, and the heat insulation plate 312 covers the first opening 3112; and the heat insulation plate 312 cooperates with the fixing structure 311 to form the fixing frame 310 wrapping the coil 320.

[0095] The fixing structure 311 is a fixing member with a first opening 3112. During installation, the coil 320 is first placed in the accommodating cavity 3111, and then the heat insulation plate 312 is fixed at the first opening 3112, so that the heat insulation plate 312 and the fixing structure 311 wrap the coil 320. In this way, the condensed water in the refrigeration cavity 121 can be prevented from entering the accommodating cavity 3111, thereby preventing the coil 320 from being short-circuited.

[0096] Furthermore, the fixing structure 311 cooperates with the heat insulation plate 312 to cover the accommodating cavity 3111. Compared with the prior art solution of surrounding the coil 320 with an entire injection molding member, the assembly is more convenient. Moreover, the heat insulation plate 312 also has a heat insulation effect, so that the fixing frame 310 has the functions of fixing the coil 320, heat insulation, and water insulation, thereby integrating multiple functions in one fixing frame 310. This is conducive to the miniaturization of the magnetic field generating assembly 300 and facilitates subsequent assembly of the refrigerator.

[0097] In addition, in other embodiments, the heat insulation plate 312 can be separated from the fixed structure 311, the fixed structure 311 can wrap the coil 320 alone, and then the heat insulation plate 312 is located between the coil 320 and the storage assembly 200 to insulate heat, so as to prevent the coil 320 from transferring heat to the storage assembly 200.

[0098] It can be understood that the heat insulation plate 312 can be made of a mica sheet, which is an excellent heat insulation material, does not affect the passage of the magnetic field, and after covering the first opening 3112, the coil 320 can be insulated and the heat generated by the coil 320 can be blocked. In addition, the mica sheet has low cost and is suitable for mass production. In addition, other heat-insulating and insulating materials such as glass fiber and asbestos can also be used for manufacturing.

[0099] In some embodiments, with reference to Figure 3 , Figure 5 and Figure 6 , the refrigerator further comprises a magnetic conducting plate 400; the magnetic conducting plate 400 is arranged on the side of the fixed frame 310 away from the heat insulation plate 312; that is, the magnetic conducting plate 400 is located on the side of the coil 320 away from the storage assembly 200, so as to strengthen the magnetic field generated by the coil 320, so that the magnetic field strength of the storage space in the storage assembly 200 is larger, so as to save the energy consumption of the coil 320 and reduce the heat generated by the coil 320 when working.

[0100] In order to improve the magnetic field enhancement effect of the magnetic conducting plate 400, the magnetic conducting plate 400 is connected to the side of the fixed frame 310 away from the heat insulation plate 312, so as to reduce the distance between the coil 320 and the magnetic conducting plate 400, thereby improving the magnetic field enhancement effect of the magnetic conducting plate 400.

[0101] In some embodiments, with reference to Figure 4 , Figure 5 and Figure 10 , the fixed structure 311 further comprises a second opening 3113, the second opening 3113 is located on the side of the fixed structure 311 facing the magnetic conducting plate 400, and the second opening 3113 communicates with the accommodating cavity 3111; the fixed frame 310 further comprises an insulation plate 313, the insulation plate 313 is located on the side of the fixed structure 311 facing the magnetic conducting plate 400; the insulation plate 313 covers the second opening 3113, and the heat insulation plate 312, the fixed structure 311 and the insulation plate 313 cooperate to form the fixed frame 310 wrapping the coil 320.

[0102] That is, the fixing structure 311 has a first opening 3112 and a second opening 3113 on opposite sides, both of which are in communication with the accommodating cavity 3111; the fixing structure 311 covers the first opening 3112 and the second opening 3113 with the insulation plate 313 and the heat insulation plate 312, so as to wrap the coil 320 in the accommodating cavity 3111, which can prevent condensed water in the refrigeration chamber 121 from entering the accommodating cavity 3111, so as to prevent the coil 320 from short circuiting.

[0103] Moreover, the insulation plate 313 covers the side facing the magnetic conductive plate 400, so as to cut off the conductive path between the coil 320 and the magnetic conductive plate 400, prevent the coil 320 from conducting with the magnetic conductive plate 400, and avoid use failure such as electric leakage. Moreover, the insulation plate 313 and the heat insulation plate 312 are separately arranged with the fixing structure 311, which can make the fixing structure 311, the insulation plate 313 and the heat insulation plate 312 easier to process and manufacture, so as to reduce the production cost.

[0104] On the basis of the above, the magnetic conductive plate 400 is attached to the side of the insulation plate 313 away from the coil 320. Since the magnetic conductive plate 400 and the coil 320 cut off the conductive path with the insulation plate 313, the magnetic conductive plate 400 directly attached to the fixing frame 310 will not cause use failure such as electric leakage.

[0105] In addition, in some other embodiments, the insulation plate 313 can be directly integrally formed with the fixing structure 311, the fixing structure 311 can hold the coil 320, and then the heat insulation plate 312 is used to cover the first opening 3112, so as to achieve the covering of the coil 320.

[0106] For example, referring to Figure 4 , Figure 10 the fixing structure 311 is a ring-shaped member, which has a first opening 3112 on the upper side and a second opening 3113 on the lower side, and has an accommodating cavity 3111 in the middle for accommodating the coil 320, and then the heat insulation plate 312 and the insulation plate 313 are used to cover the first opening 3112 and the second opening 3113, so as to wrap the coil 320 in the accommodating cavity 3111, that is, to complete the assembly of the coil 320 and the fixing frame 310.

[0107] It can be understood that the insulation plate 313 can be made of mica sheet, which is an excellent heat insulation and insulation material, does not affect the passage of the magnetic field, and after covering the second opening 3113, can insulate the coil 320 and block the heat generated by the coil 320. Moreover, the mica sheet has low cost and is suitable for mass production. In addition, other heat insulation and insulation materials such as glass fiber and asbestos can also be used for manufacturing.

[0108] In some embodiments, referring to Figure 8The heat insulation plate 312 comprises a first cover portion 3121 and a first extension portion 3122. The first cover portion 3121 is connected with the first opening 3112, and the first cover portion 3121 covers the first opening 3112. The first extension portion 3122 is arranged at the outer edge of the first cover portion 3121, and the first extension portion 3122 extends in a direction away from the center of the first opening 3112.

[0109] The first extension portion 3122 is located at the outer edge of the first cover portion 3121, and extends in a direction away from the center of the first opening 3112, i.e. the first extension portion 3122 extends to the outside of the first opening 3112. The first extension portion 3122 is annular, i.e. the outer edge of the first cover portion 3121 extends outwardly as a whole to form the first extension portion 3122, so that the heat insulation plate 312 can cover the entire fixing structure 311, and the heat insulation plate 312 is connected with the fixing structure 311.

[0110] The heat insulation plate 312 can be connected with the fixing structure 311 by means of adhesives, screws or other fastening methods, so that the heat insulation plate 312 covers the first opening 3112, and the heat insulation plate 312 is connected with the fixing structure 311 as a whole, facilitating assembly.

[0112] The second extension portion 3132 is located at the outer edge of the second cover portion 3131, and extends in a direction away from the center of the second opening 3113, i.e. the second extension portion 3132 extends to the outside of the second opening 3113. The second extension portion 3132 is annular, i.e. the outer edge of the second cover portion 3131 extends outwardly as a whole to form the second extension portion 3132, so that the insulation plate 313 can cover the entire fixing structure 311, and the insulation plate 313 is connected with the fixing structure 311.

[0114] In some embodiments, with reference to Figure 3 , Figure 5 ,Figure 7 The refrigerator further comprises a heat dissipation structure 500 arranged on the tank 120, and a heat dissipation air duct is formed between the heat dissipation structure 500 and the tank 120; the heat dissipation air duct is in communication with the refrigeration chamber 121; and the fixing frame 310 and the coil 320 are both located in the heat dissipation air duct.

[0115] That is, the cold air of the refrigerator enters the heat dissipation air duct after passing through the refrigeration chamber 121, and the cold air can cool the fixing frame 310 located in the heat dissipation air duct, thereby taking away the heat generated by the coil 320 during operation, avoiding the accumulation of heat of the coil 320 and the fixing frame 310 during use, ensuring that the temperature of the magnetic field generating assembly 300 located on one side of the storage assembly 200 is not too high, and further ensuring that the storage assembly 200 does not appear a local temperature too high condition, and ensuring the preservation effect of the refrigerator.

[0116] In some embodiments, with reference to Figure 10 In order to better dissipate the heat of the coil 320 into the heat dissipation air duct, the fixing structure 311 comprises: a heat dissipation hole 3114 in communication with the accommodating cavity 3111; and the heat dissipation air duct is in communication with the accommodating cavity 3111 through the heat dissipation hole 3114.

[0117] The space in the accommodating cavity 3111 is in communication with the heat dissipation air duct through the heat dissipation hole 3114, and the heat of the coil 320 in the accommodating cavity 3111 can be dissipated into the heat dissipation air duct through the heat dissipation hole 3114, or cold air can enter the heat dissipation hole 3114 to take away the heat of the coil 320, thereby reducing the temperature of the coil 320 and the fixing frame 310, avoiding the temperature of the magnetic field generating assembly 300 being too high, and ensuring that the magnetic field generating assembly 300 can operate normally.

[0118] In some embodiments, with reference to Figure 2 , Figure 5 and Figure 6 The tank 120 is provided with: an accommodating groove 122; the accommodating groove 122 is in communication with the refrigeration chamber 121, and the accommodating groove 122 is located on one side of the storage assembly 200; the magnetic field generating assembly 300 is located in the accommodating groove 122, and the heat dissipation structure 500 covers the accommodating groove 122, so that a heat dissipation air duct is formed between the heat dissipation structure 500 and the accommodating groove 122.

[0119] The accommodating groove 122 and the magnetic field generating assembly 300 are both located on the same side of the storage assembly 200, and the accommodating groove 122 and the magnetic field generating assembly 300 are covered by the heat dissipation structure 500, so that the accommodating groove 122 and the magnetic field generating assembly 300 are not exposed, thereby reducing the case that the user reaches into the heat dissipation air duct and accidentally touches the magnetic field generating assembly 300.

[0120] For example, with reference to Figure 2 、 Figure 5 , the accommodation groove 122 is located on the lower side of the storage assembly 200, and the corresponding heat dissipation structure 500 and the magnetic field generating assembly 300 are also located on the lower side of the storage assembly 200. The opening of the drawer of the storage assembly 200 faces upward, so that the accommodation groove 122, the heat dissipation structure 500, and the magnetic field generating assembly 300 are all arranged on the lower side of the storage assembly 200, so that the magnetic field generating assembly 300 does not occupy the space above the storage assembly 200, thereby avoiding affecting the volume of the drawer of the storage assembly 200.

[0121] In addition, the accommodation groove 122 can also be arranged on the upper side, front side, rear side, left side, right side, etc. of the storage assembly 200, so as to accommodate the magnetic field generating assembly 300.

[0122] For example, with reference to Figure 3 、 Figure 6 and Figure 11 , the heat dissipation structure 500 comprises a base plate part 510, a first support part 520, and a second support part 530. The base plate part 510 covers the accommodation groove 122, and the base plate part 510 cooperates with the groove wall of the accommodation groove 122 to form the heat dissipation air duct. The first support part 520 is arranged on the base plate part 510 and is in contact with the groove wall of the accommodation groove 122. The second support part 530 is arranged on the base plate part 510 and is in contact with the inner wall of the box body 120.

[0123] The first support part 520 and the second support part 530 cooperate to support the entire heat dissipation structure 500 on the side of the accommodation groove 122 facing the storage assembly 200, so that the base plate part 510 and the accommodation groove 122 form a heat dissipation air duct, which facilitates the cold air to enter the heat dissipation air duct to cool and dissipate heat for the magnetic field generating assembly 300, thereby ensuring that the temperature of the magnetic field generating assembly 300 does not become too high.

[0124] For example, with reference to Figure 5 、 Figure 6 、 Figure 11 , the first support part 520 has a plurality of first support parts 520 arranged at the inlet and outlet of the heat dissipation air duct. Adjacent two first support parts 520 form an air inlet to allow cold air to enter the heat dissipation air duct. The second support part 530 is arranged on both sides of the inlet and outlet to support the base plate part 510 in cooperation with the groove wall of the box body 120.

[0125] In conclusion, the refrigerator of the embodiment sets the heat insulation plate 312 at the position between the coil 320 and the storage assembly 200 to cut off the heat transfer route of the coil 320 and the storage assembly 200, prevent the heat generated by the coil 320 during operation from being transferred to the storage assembly 200 through the space between the coil 320 and the storage assembly 200, and then the heat generated by the coil 320 during operation cannot be transferred to the storage assembly 200, avoid the food temperature in the storage assembly 200 from being increased due to the heat of the coil 320, make the food in the storage assembly 200 be preserved according to the expected magnetic field, and ensure the food preservation effect of the refrigerator.
