Description
Technical Field
[0001] The utility model relates to the technical field of household appliances, in particular to a refrigerator. Background Art
[0002] Refrigerators are a common household appliance in our daily lives. With technological advancements, refrigerators are providing increasingly diverse functions. Currently, some refrigerators incorporate electromagnetic coils within the storage compartment. These coils generate a magnetic field that activates the water molecules within the food stored within the compartment. This alters the ion distribution within the food, reduces the activity of various metabolic enzymes within the food and bacteria, and inhibits or slows food spoilage, preserving the food's freshness.
[0003] However, existing refrigerators equipped with magnetic components mostly use electromagnetic coils wrapped around drawers. To achieve the required magnetic field strength inside the drawers, the electromagnetic coils often have to be large, weighing at least several kilograms. This not only increases the cost of the electromagnetic coils but also limits the storage compartment's assembly space, hindering the efficient use of the interior storage space. Utility Model Content

The magnetic induction intensity of the axial magnetic field varies along the height direction of the drawer, so that the magnetic field generated by the magnetic member can adapt to the items stored in the drawer, thereby enabling the magnetic member to meet the freshness requirements of the items in the drawer with a smaller specification size, thereby reducing the preparation cost of the magnetic component and reducing the occupancy rate of the magnetic component in the interior space of the first chamber.
[0012] In some embodiments, the magnetic member is an electromagnetic coil, and the magnetic assembly further comprises:

[0024] The above technical solution has the following advantages: the magnetic part adopts a single-coil structure, which can control the specifications and dimensions of the magnetic components configured in the drawer, reduce the weight of the magnetic part, and thus reduce the preparation cost of the magnetic part.
[0025] In some embodiments, the drawer has a storage space therein, the height of the storage space is H, the shortest vertical distance between the bottom of the magnetic member and the bottom of the storage space is L, and L=0.3H~0.5H.
[0026] The above technical solution has the following advantages: the magnetic part constitutes an annular magnet and generates an axial magnetic field. The magnetic induction intensity of the axial magnetic field varies along the height direction of the drawer. In the axial direction of the axial magnetic field, the magnetic induction intensity decreases as the distance from the magnetic part increases. By arranging the magnetic part at a preset height, the area with higher magnetic induction intensity of the magnetic field can cover the items placed in the drawer, so as to make full use of the magnetic field, so that the magnetic part can meet the preservation needs of the items in the drawer with smaller specifications and dimensions.
[0027] In some embodiments, the magnetic assembly further comprises:
[0028] The magnetic conductive block is used to cooperate with the magnetic component, wherein:
[0029] The magnetic conductive block is connected to the bottom of the drawer so that the magnetic conductive block can move synchronously with the drawer; or,

[0043] Compared with the prior art, the refrigerator implemented by the utility model has the following beneficial effects:
[0044] This refrigerator disposes a magnetic component on the drawer and connects the magnetic component to the outer periphery of the drawer so that the magnetic component can move synchronously with the drawer. In addition, the magnetic component is arranged around the opening, so that the magnetic component forms a ring magnet and generates an axial magnetic field. The drawer opening is located in the magnetic field direction of the axial magnetic field, and the magnetic induction intensity of the axial magnetic field varies along the height direction of the drawer. That is, in the height direction of the drawer, the magnetic induction intensity of the axial magnetic field decreases as it moves away from the magnetic component. In this way, items stored in the drawer fall into an area with higher magnetic induction intensity. The magnetic component can generate a magnetic induction intensity sufficient to meet the needs of keeping items fresh with a smaller specification size, thereby reducing the preparation cost of the magnetic component and reducing the occupancy rate of the magnetic component in the interior of the first chamber.
[0045] Moreover, by arranging a magnetic component with a single coil structure on the drawer, the refrigerator can further control the specifications and dimensions of the magnetic components configured in the drawer, reduce the weight of the magnetic component, and thus reduce the preparation cost of the magnetic component.
[0046] Moreover, by providing a magnetic conductive block and cooperating with the magnetic component, the refrigerator can effectively increase the magnetic field strength of the magnetic field generated by the magnetic component. In this way, the specifications and dimensions of the magnetic component provided on the drawer can be further reduced, thereby reducing the weight of the magnetic component. Moreover, when the magnetic component is an electromagnetic coil, the effect of the working heat of the electromagnetic coil on the temperature inside the first compartment can be reduced.

[0061] In the description of the present invention, it should be understood that the terms "height", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like used in the present invention to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0062] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features.
[0063] See Figure 1 An embodiment of the present invention provides a refrigerator 100, comprising a cabinet 1 and a door (not shown in the figure), wherein the cabinet 1 is formed with a take-in / take-out opening 2; the door is connected to the cabinet 1 and can move relative to the cabinet 1 to open and close the take-in / take-out opening 2.
[0064] The box body 1 is roughly a rectangular frame structure. The box body 1 includes a box shell 1a and a box liner 1b. The box liner 1b is arranged in the box shell 1a. A foam space (not shown in the figure) is formed between the box liner 1b and the box shell 1a. The foam space is used to install other component structures of the refrigerator 100 and form a foam insulation layer. The box shell 1a provides protection and support for the box liner 1b. A refrigeration compartment is formed in the box liner 1b for storing food. The access port 2 is provided on one side of the refrigeration compartment to facilitate the taking and placing of items into the refrigeration compartment. The door body can be connected to the box shell 1a of the box body 1 in an openable and closable manner. For example, the door body and the box shell 1a can be rotatably connected or slidably connected.
[0065] In some embodiments, the refrigerator 100 also includes a refrigeration system (not shown in the figure) and an air supply system (not shown in the figure), and the refrigeration system and the air supply system are electrically connected to a power supply component, and the power supply component is used to supply electricity to various components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.
[0066] The refrigeration system is installed within the housing 1a and is used to provide cold air to the refrigerated compartment within the housing 1b. A refrigeration system generally refers to a closed system consisting of components such as a compressor, an evaporator, a condenser, a filter drier, a return air pipe, and a throttling device, as well as a refrigerant. Each component is located at different locations within the housing 1a according to its structural characteristics to meet its corresponding functional requirements. The operating process of the refrigeration system mainly includes compression, condensation, throttling, and evaporation. The compression process is as follows: After the power cord of the refrigerator 100 is plugged in and the thermostat contacts are connected, the compressor begins to operate. The low-temperature, low-pressure refrigerant from the evaporator is drawn into the compressor, compressed by the compressor into a high-temperature, high-pressure refrigerant gas, and then discharged into the condenser. The condensation process is as follows: The high-temperature, high-pressure refrigerant gas exchanges heat with the external environment through the condenser, causing its temperature to drop, gradually cooling to a saturated refrigerant vapor at room temperature and high pressure, and then to a saturated refrigerant liquid. The throttling process involves the condensed, saturated refrigerant liquid being filtered through a filter drier to remove moisture and impurities before flowing into a throttling device. The throttling device throttles and reduces the pressure, turning the refrigerant into a wet vapor at room temperature and low pressure. The evaporation process involves the wet vapor at room temperature and low pressure entering the evaporator, where it begins to absorb heat and vaporize, lowering the temperature of the evaporator and its surroundings, achieving refrigeration and turning the refrigerant into a low-temperature, low-pressure gas. The refrigerant exiting the evaporator returns to the compressor, where the above process repeats. This change in the refrigerant's state results in energy conversion, transferring heat from the refrigerator 100 to the air outside, thus completing the refrigerator 100's refrigeration cycle.
[0067] The air supply system is installed in the box shell 1a and is used to provide power for the flow of cold air. The air supply system generally includes a fan and an air supply duct defined in the box shell 1a. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan. In other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box shell 1a also defines a duct cavity, which is connected to the air supply duct and the refrigeration compartment inside the box 1b, so that the air supply duct is connected to the refrigeration compartment through the duct cavity. It should be noted that the box 1b is provided with an air outlet, which is used to connect the air supply duct cavity and the refrigeration compartment. When the fan is running, the cold air generated by the refrigeration system enters the air supply duct cavity through the air supply duct and flows from the air outlet to the refrigeration compartment to cool the refrigeration compartment. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall of the box 1b on the side opposite to the access opening 2 of the refrigeration compartment or on the side wall of the box 1b on the side adjacent to the access opening 2 of the refrigeration compartment; it should also be noted that the refrigeration system and the air supply system belong to the common knowledge technology in this field and will not be described in detail here.
[0068] refer to Figure 1-11In the refrigerator 100 of the present embodiment, a plurality of refrigeration compartments are provided within the housing 1, at least one of which is a first compartment 3. Depending on the function of the refrigerator 100, the first compartment 3 can be either a freezer compartment or a refrigerator compartment. The following description of this embodiment assumes that the first compartment 3 is a freezer compartment. The directions described herein are based on the direction in which a user faces the refrigerator 100. The left and right sides are defined as the user facing the refrigerator 100. The side of the refrigerator 100 facing the user during use is defined as the front side, and the side opposite thereto is defined as the rear side. The top and bottom sides of the refrigerator 100 during normal operation are defined as the top and bottom sides, respectively.
[0069] A drawer 4 is disposed within the first chamber 3. The drawer 4 is movable in a predetermined direction within the first chamber 3 and has an opening 5 for allowing items to enter and exit the drawer 4. Generally, the opening 5 is positioned upward to facilitate the user's access to and placement of items. It is understood that a guide structure is typically provided within the first chamber 3 to guide the drawer 4 in its predetermined direction of movement. For example, a guide rail may be provided within the first chamber 3, and the drawer 4 may be mounted on the guide rail. In this manner, the guide rail's direction serves as the predetermined direction of movement for the drawer 4, and the drawer 4 enters and exits the first chamber 3 along the guide rail's direction of movement.
[0070] refer to Figure 1-4 A magnetic component 6 is provided on the drawer 4 for generating a magnetic field, wherein the magnetic component 6 includes a magnetic part 6a, which can generate a magnetic field, and the magnetic part 6a is connected to the outer periphery of the drawer 4 so that the magnetic part 6a can move synchronously with the drawer 4; and the magnetic part 6a is arranged around the opening 5 so that the opening 5 is in the magnetic field direction of the magnetic field.
[0071] The magnetic member 6a can be a soft magnetic material, such as an electromagnetic coil. For example, if the magnetic member 6a is arranged around the opening 5, the magnetic member 6a forms a ring. When current flows through the magnetic member 6a, it generates an axial magnetic field. The direction of this axial magnetic field can be toward or away from the opening 5, positioning the opening 5 of the drawer 4 in the direction of the axial magnetic field.
[0072] It is understood that the magnetic flux density of the axial magnetic field varies along the axis, with the highest magnetic flux density occurring in the area surrounded by the magnetic element 6a. Furthermore, the magnetic flux density of the axial magnetic field decreases as one moves away from the magnetic element 6a in the height direction of the drawer 4. Since the drawers 4 in the refrigerator 100 are generally positioned horizontally, items are stacked along the height direction of the drawers 4. Consequently, the direction of variation of the magnetic flux density of the axial magnetic field can adapt to the stacking direction of the items, allowing items stored in the drawer 4 to fall within the area of higher magnetic flux density. This allows the magnetic element 6a to generate a magnetic flux density sufficient to maintain freshness, even with smaller dimensions, such as a smaller wire diameter and a smaller number of turns. This reduces the manufacturing cost of the magnetic assembly 6 and reduces the space occupied by the magnetic assembly 6 within the first chamber 3.
[0073] It should be noted that the number of magnetic members 6a connected to the outer periphery of the drawer 4 can be one or more. Taking the electromagnetic coil as an example, the magnetic member 6a can be configured according to its required operating power. For example, based on the temperature requirements of the first chamber 3, the operating power of the electromagnetic coil needs to be limited to a certain range. In this case, the wire diameter, number of turns, quantity, and operating current of the electromagnetic coil can be adjusted to ensure that the overall rated power of the electromagnetic coil meets the set requirements. Moreover, when multiple magnetic members 6a are arranged at intervals along the height direction of the drawer 4, the wire diameter and number of turns of each electromagnetic coil will be smaller than the wire diameter and number of turns of a single electromagnetic coil when only one electromagnetic coil is arranged. In this way, even if there are multiple magnetic members 6a connected to the outer periphery of the drawer 4, the weight of the multiple magnetic members 6a can still be controlled within an appropriate range, avoiding the specifications and dimensions of the magnetic members 6a being too large.
[0074] Of course, in other examples, the magnetic member 6a may also be a permanent magnet. When a permanent magnet is used, the magnetization direction of the magnetic member 6a needs to be adapted to the height direction of the drawer 4, so that the magnetic field generated by the magnetic member 6a is directed toward the opening 5 or away from the opening 5, so that the opening 5 of the drawer 4 is in the magnetic field direction of the axial magnetic field.
[0075] In the case where the magnetic member 6a is an electromagnetic coil, the refrigerator 100 needs to configure a conductive structure for the magnetic member 6a to ensure that the magnetic member 6a can be supplied with current, thereby generating a magnetic field. Figure 5As an example of this embodiment, the magnetic assembly 6 further includes a first conductive member 6b and a second conductive member 6c. The first conductive member 6b is disposed within the first compartment 3 and is connected to a power source. The second conductive member 6c is disposed on the rear side of the drawer 4 and is capable of moving synchronously with the drawer 4. The second conductive member 6c is connected to the magnetic member 6a and is detachably connected to the first conductive member 6b. Thus, when the first conductive member 6b and the second conductive member 6c are connected, the magnetic member 6a is connected to the power source, causing the magnetic member 6a to generate a magnetic field. When the first conductive member 6b and the second conductive member 6c are disconnected, the magnetic member 6a is disconnected from the power source, causing the magnetic member 6a to cease generating a magnetic field.
[0076] The first conductive member 6b and the second conductive member 6c can be docking terminals, one of which is the female end of the docking terminal and the other is the male end of the docking terminal. When the drawer 4 is hidden in the first compartment 3, the first conductive member 6b is connected to the second conductive member 6c, so that the first conductive member 6b and the second conductive member 6c are conductive, thereby allowing the magnetic member 6a to pass current to generate a magnetic field. After the user pulls the drawer 4 out of the first compartment 3, the first conductive member 6b will be separated from the second conductive member 6c, and the magnetic member 6a will be powered off, thereby stopping the generation of the magnetic field. In this way, the magnetic component 6 can adapt to the state of the drawer 4, and the user experience is better.
[0077] Of course, the conductive structure can also be connected to the magnetic member 6a through the wire 6d to keep the magnetic member 6a conductive. Figure 6 As an example of this embodiment, in the case where the magnetic member 6a is an electromagnetic coil, the magnetic assembly 6 may include a first conductive member 6b, a wire 6d, and a second conductive member 6c, wherein the first conductive member 6b is arranged in the first chamber 3 and is connected to the power supply; the wire 6d is arranged on the back side of the drawer 4 and is connected to the magnetic member 6a; the second conductive member 6c is arranged on the wire 6d and is connected to the first conductive member 6b, so that the magnetic member 6a is connected to the power supply and the magnetic member 6a generates a magnetic field.
[0078] By connecting the first conductive member 6b and the second conductive member 6c using the wire 6d, the first conductive member 6b and the second conductive member 6c can remain conductive, allowing current to continuously flow into the magnetic member 6a, causing the magnetic member 6a to continuously generate a magnetic field. Of course, in some examples, a corresponding sensor switch can also be provided on the first compartment 3 or the drawer 4. The sensor switch can be used to determine whether the drawer 4 is pulled out of the first compartment 3 and thereby control the flow of current. Of course, when the drawer 4 is hidden in the first compartment 3, the wire 6d will be stored between the drawer 4 and the first compartment 3. A storage structure or storage space will need to be configured in the first compartment 3 to facilitate the storage of the wire 6d.
[0079] Magnetic component 6a utilizes an electromagnetic coil, which can control magnetic field variations. Depending on the magnitude of the input current, magnetic component 6a can generate magnetic fields of varying strengths, allowing these magnetic fields to be compatible with different items, adapting to the storage requirements of drawer 4. Considering that an oversized coil would affect the preparation and installation of magnetic component 6a, if magnetic component 6a is an electromagnetic coil, it can be a single coil. The simple structure of a single coil helps reduce the weight of magnetic component 6a, thereby reducing the manufacturing cost of magnetic component 6a.
[0080] It should be noted that the magnetic induction intensity of the axial magnetic field varies along the height direction of the drawer 4. In the axial direction of the axial magnetic field, the magnetic induction intensity decreases as it moves away from the magnetic member 6a. In order to ensure that the items in the drawer 4 are in the area with higher magnetic induction intensity, the position of the magnetic member 6a in the drawer 4 can be adjusted. Figure 3 As an example of this embodiment, the drawer 4 has a storage space 7, the height of the storage space 7 is H, and the shortest vertical distance between the bottom of the magnetic member 6a and the bottom of the storage space 7 is L, and L = 0.3H ~ 0.5H.
[0081] By installing the magnetic part 6a in the middle position of the drawer 4 in its height direction, the area with the largest magnetic induction intensity of the magnetic field generated by the magnetic part 6a is also close to the middle position of the storage space 7 in its height direction, and the magnetic induction intensity of the magnetic field will decrease from the middle position upward and downward respectively, so that the entire storage space 7 can be located in an area with higher magnetic induction intensity. Moreover, the items stored in the drawer 4 are generally stacked in the height direction of the drawer 4, so that the items on the same layer can be located in the area with the largest magnetic induction intensity, thereby obtaining a good insurance effect.
[0082] To strengthen the magnetic field, magnetic assembly 6 may also be equipped with a conductive block 6e, which cooperates with magnetic element 6a to enhance the magnetic field strength. The provision of conductive block 6e increases the magnetic field strength generated by magnetic element 6a, further reducing the size of magnetic element 6a. This can particularly reduce heat generation during operation of electromagnetic coils, thereby minimizing the impact of magnetic element 6a on the temperature within first chamber 3.
[0083] The assembly methods of the magnetic block 6e are quite diverse. Figure 7 As an example of this embodiment, the magnetic block 6e can be connected to the bottom of the drawer 4 so that the magnetic block 6e can move synchronously with the drawer 4. Of course, the magnetic block 6e can be connected to the outer surface of the drawer 4 or embedded in the drawer 4. These connection methods can all achieve synchronous movement of the magnetic block 6e and the drawer 4.
[0084] Alternatively, refer to Figure 8As another example of this embodiment, the magnetic block 6e is disposed in the first chamber 3, connected to the top inner wall of the first chamber 3 and close to the opening 5 of the drawer 4, but the magnetic block 6e is not connected to the drawer 4. When the drawer 4 moves in a specified direction in the first chamber 3, the magnetic block 6e remains stationary in the first chamber 3, while the magnetic member 6a moves with the drawer 4, approaching and moving away from the magnetic block 6e.
[0085] Or, refer to Figure 9 As another example of this embodiment, the magnetic block 6e is detachably connected to the opening 5, allowing the magnetic block 6e to move synchronously with the drawer 4. For example, the magnetic block 6e can be formed into a plate-like structure and serve as a cover for the opening 5 of the drawer 4. When the drawer 4 is stored in the first compartment 3, the magnetic block 6e covers the opening 5, sealing the drawer 4 opening 5. When the user needs to place or remove items, the user removes the magnetic block 6e, opening the drawer 4 opening 5.
[0086] In order to prevent the magnetic member 6a from being directly wound around the outer periphery of the drawer 4, the magnetic member 6a is exposed. Figure 1-4 As an example of this embodiment, the drawer 4 may be provided with a mounting groove 8, which is arranged around the opening 5 and has a notch facing the outer periphery of the drawer 4. The magnetic member 6a is disposed in the mounting groove 8, and in the depth direction of the mounting groove 8, the maximum vertical distance from the magnetic member 6a to the bottom of the mounting groove 8 is S, the groove depth of the mounting groove 8 is D, and S≤D.
[0087] By providing a mounting groove 8 in the drawer 4, the magnetic component 6a can be accommodated in the mounting groove 8, and by controlling the relationship between the maximum vertical distance S from the magnetic component 6a to the bottom of the mounting groove 8 and the groove depth D of the mounting groove 8, so that S≤D, it can be ensured that the magnetic component 6a is completely accommodated in the mounting groove 8 and will not be exposed from the mounting groove 8, so that the mounting groove 8 can provide good protection for the magnetic component 6a, and avoid the user colliding with the magnetic component 6a and damaging the magnetic component 6a when pulling the drawer 4.
[0088] Furthermore, based on the interaction between the magnetic member 6a and the mounting groove 8, the dimensions of the magnetic member 6a can be controlled by controlling the groove depth D of the mounting groove 8. For example, if the groove depth D of the mounting groove 8 satisfies the following condition: 2≤D≤10mm, then the dimension of the magnetic member 6a in the depth direction of the mounting groove 8 will also be controlled within the range of 2 to 10mm.
[0089] A protective structure can also be installed at the slot position of the installation slot 8 to seal the magnetic part 6a in the installation slot 8, providing better protection for the magnetic part 6a, and preventing the user from accidentally touching the magnetic part 6a during the process of pulling the drawer 4, thereby affecting the normal operation of the magnetic part 6a or causing safety risks. Figure 10-11As an example of this embodiment, the mounting groove 8 is connected to a cover plate 9, which covers the notch of the mounting groove 8, and the cover plate 9 is flush with the outer surface of the drawer 4, or the cover plate 9 protrudes from the outer surface of the drawer 4.
[0090] The cover plate 9 and the notch of the mounting slot 8 are generally detachably connected, so that the user can remove the cover plate 9 and replace or repair the magnetic part 6a. In addition, a plurality of through holes 10 may be provided on the cover plate 9, and the plurality of through holes 10 are arranged along the thickness direction of the cover plate 9, so that the magnetic part 6a can timely divert the heat generated by the magnetic part 6a during operation through the through holes 10. Of course, the aperture of the through hole 10 needs to be controlled within a certain range. For example, the maximum aperture of the through hole 10 is d, 0<d≤3mm, to prevent the user from accidentally touching the magnetic part 6a, affecting the normal operation of the magnetic part 6a or causing safety risks.
[0091] It should be noted that the outer contour of the through hole 10 can be a variety of shapes such as circular, square, racetrack, elliptical, etc. The maximum aperture d of the through hole 10 refers to different dimensions depending on the outer contour of the through hole 10. In the case where the outer contour of the through hole 10 is circular, the maximum aperture d of the through hole 10 is the diameter of the through hole 10, while in the case where the outer contour of the through hole 10 is rectangular, the maximum aperture d of the through hole 10 is the length of the long side of the through hole 10. Figure 11 In the case where the outer contour of the through hole 10 is a racetrack shape, the maximum aperture d of the through hole 10 is the sum of the two arc radii and the length of the long side of the through hole 10 .
[0092] In summary, the embodiment of the present invention provides a refrigerator 100 in which a magnetic member 6a is provided on the drawer 4 and connected to the outer periphery of the drawer 4 so that the magnetic member 6a can move synchronously with the drawer 4, and the magnetic member 6a is arranged around the opening 5, so that the magnetic member 6a constitutes a ring magnet and generates an axial magnetic field. The opening 5 of the drawer 4 is in the magnetic field direction of the axial magnetic field, and the magnetic induction intensity of the axial magnetic field will change along the height direction of the drawer 4, that is, in the height direction of the drawer 4, the magnetic induction intensity of the axial magnetic field will decrease as it moves away from the magnetic member 6a. In this way, the items stored in the drawer 4 will fall in the area with higher magnetic induction intensity. The magnetic member 6a can generate a magnetic induction intensity sufficient to meet the needs of keeping the items fresh with a smaller specification size, thereby reducing the preparation cost of the magnetic component 6 and reducing the occupancy rate of the magnetic component 6 in the internal space of the first chamber 3.
[0093] Moreover, by providing a magnetic member 6a with a single coil structure on the drawer 4, the refrigerator 100 can further control the specifications and dimensions of the magnetic component 6 configured in the drawer 4, reduce the weight of the magnetic member 6a, and thus reduce the preparation cost of the magnetic member 6a.
[0094] Furthermore, the refrigerator 100 is provided with a magnetic conductive block 6e. By using the magnetic conductive block 6e in conjunction with the magnetic component 6a, the magnetic field strength of the magnetic component 6a can be effectively increased. As a result, the size of the magnetic component 6a provided on the drawer 4 can be further reduced, thereby reducing the weight of the magnetic assembly 6. Furthermore, when the magnetic component 6a is an electromagnetic coil, the effect of the heat generated by the electromagnetic coil on the temperature inside the first chamber 3 can be reduced.
[0095] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
