Description

Technical Field

[0001] The utility model relates to the technical field of household refrigeration equipment, in particular to a magnetic field module for a refrigerating and freezing storage device and a refrigerating and freezing storage device. Background Art

[0002] For traditional refrigerating and freezing storage devices, improving the fresh-keeping effect of food materials mainly relies on precise temperature control, accelerating the refrigeration speed or reducing the storage temperature (deep refrigeration). These means of fresh-keeping and storing food materials through temperature are costly and have complex control means. In recent years, those skilled in the art have also actively tried to use other fresh-keeping and storing technologies.

[0003] Now it is found through research that the magnetic field also has a certain influence on the fresh-keeping and storage of food materials. Under the action of the magnetic field, small water molecule clusters or ice nuclei formed by single water molecules are difficult to aggregate water molecules to grow orderly into large ice crystals and appear in the form of micro ice crystals. This not only enables the freezing process to quickly pass through the phase change stage, but also reduces the damage of ice crystals to food cells. Therefore, introducing a suitable magnetic field into the refrigerating and freezing storage device can be beneficial to improving the fresh-keeping and storage effect of food materials.

[0004] In the prior art, there is also a solution in which a magnetic field component is arranged in the storage compartment of a refrigerator to form a fresh-keeping and storing space. However, during the installation process, it is difficult to position the magnetic field component. Especially in the solution where a magnetic source component and a magnetic conductive plate jointly form a magnetic field module, it is difficult to achieve the expected state for both the relative position and the fitting degree between the two, which brings difficulties to mass production. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a magnetic field module for a refrigerating and freezing storage device and a refrigerating and freezing storage device that at least partially solve the above problems, and ensure the relative position relationship between the magnetic source component and the magnetic conductive plate.

[0006] A further object of the utility model is to prevent the magnetic field module from being corroded and damaged and extend the service life of the magnetic field module.

[0048] Those skilled in the art should understand that the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments of the present utility model. This part of the embodiments is intended to explain the technical principles of the present utility model, rather than to limit the protection scope of the present utility model. Based on the embodiments provided by the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts should still fall within the protection scope of the present utility model.

[0049] In the description of this embodiment, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this embodiment 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 thus cannot be understood as a limitation to the present utility model. For example, except for individual clear other orientation limitations, for a refrigerating and freezing device in the form of a refrigerator, the direction of the box body facing the door body is the front, the direction opposite to the direction of the door body facing the box body is the rear, the direction facing the supporting ground is the lower, and the direction opposite to the ground is the upper.

[0050] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise clearly and specifically defined.

[0051] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0052] This embodiment provides a magnetic field module for a refrigerating and freezing storage device. The refrigerating and freezing device is a storage device including a refrigeration system, and a specific implementation form thereof is a refrigerator. The refrigeration system can be a common compression refrigeration system, which provides cooling capacity to the storage compartment in the form of direct cooling and / or air cooling, for example, so that the storage compartment has a desired preservation temperature. The magnetic field module is installed in the storage compartment, and the freshness preservation effect is improved by applying a magnetic field.

[0053] Figure 1 is a schematic diagram of a magnetic field module 150 for a refrigerating and freezing storage device according to an embodiment of the present utility model, Figure 2 isFigure 1 Exploded view of the components of the magnetic field module 150 in the refrigerating and freezing storage device shown. Generally, the magnetic field module 150 may include: a packaging housing, a magnetic source member 153, and a magnetic conductive plate 152. An installation space is defined inside the packaging housing; the magnetic source member 153 is disposed in the installation space and is used to generate a magnetic field; the magnetic conductive plate 152 is disposed in the installation space and is arranged in contact with the magnetic source member, and is used to adjust the magnetic field distribution of the magnetic source member.

[0054] In some embodiments, the magnetic source member 153 may be a permanent magnet sheet made of a permanent ferrite material formed by a calendering process or a sintering process. For example, the permanent magnet sheet may be made of a permanent magnetic material with a certain flexibility. For example, a flexible rubber magnet sheet made by compounding bonded ferrite magnetic powder and synthetic rubber and formed by a calendering process may be used.

[0055] The magnetic conductive plate 152 is disposed in the installation space and is arranged in contact with the magnetic source member 153, and is used to adjust the magnetic field distribution of the magnetic source member 153. The magnetic conductive plate 152 is made of a material with low coercivity and high magnetic permeability, and its area may be slightly larger than that of the magnetic source member 153. The close fit between the magnetic conductive plate 152 and the magnetic source member 153 can achieve a zero-gap fit, improving the uniformity of the magnetic field. After testing, the magnetic conductive plate 152 can make the magnetic field more uniform and expand the coverage range of the magnetic field.

[0056] The packaging housing is configured to make the magnetic source member 153 closer to the fresh-keeping storage space relative to the magnetic conductive plate 152. That is, after the magnetic field module 150 is installed in the refrigerating and freezing storage device, the side of the magnetic source member 153 opposite to the magnetic conductive plate 152 faces the magnetic field fresh-keeping space and is closer to the magnetic field fresh-keeping space than the magnetic conductive plate 152. In view of the characteristic that the magnetic field intensity gradually decays with distance, improvements are made to make full use of the magnetic field released by the magnetic source member 153.

[0057] The magnetic field module 150 includes, from outside to inside according to its position relative to the fresh-keeping storage space: a second housing 154, a magnetic conductive plate 152, a magnetic source member 153, and a first housing 151. The second housing 154 and the first housing 151 are buckled with each other (it can also be said that the second housing 154 covers the first housing 151), jointly defining a space for accommodating the magnetic conductive plate 152 and the magnetic source member 153.

[0058] In an embodiment where the magnetic field module 150 is arranged below the magnetic field fresh-keeping space, the first housing 151 may be the upper half of the packaging housing of the magnetic field module 150, and the second housing 154 may be the lower half of the packaging housing of the magnetic field module 150.

[0059] Figure 3 It is a schematic diagram of the first housing 151 and its partial enlargement in the magnetic field module 150 for a refrigerating and freezing storage device according to an embodiment of the present invention;Figure 4 It is a schematic diagram of the second housing 154 of the magnetic field module 150 in the refrigerating and freezing storage device 10 with a magnetic field module according to an embodiment of the present utility model and its partial enlargement.

[0060] The encapsulation housing may include: a first housing 151 and a second housing 154. The first housing 151 includes a first panel 1512 and a first side wall 1513 provided at the edge of the first panel 1512. The first panel 1512 abuts against one side of the magnetic source member 153. And a first positioning structure 172 and a second positioning structure 171 are respectively provided on the wall surface of the first panel 1512 that abuts against the magnetic conduction plate 152, that is, the inner surface of the first panel 1512. The second housing 154 may include: a second panel 1514 and a second side wall 1515. The second panel 1514 is arranged opposite and spaced apart from the first panel 1512. The second side wall 1515 is provided at the edge of the second panel 1514, and a plurality of mutually cooperating snap connection structures and / or screw connection structures are provided on the second side wall 1515 and the first side wall 1513, so as to realize the connection between the first housing 151 and the second housing 154, that is, as the circumferential side connection portions 163, 164.

[0061] The second panel 1514 abuts against the side of the magnetic conduction plate 152 opposite to the magnetic source member 153, and support ribs 181 are respectively provided in the regions of the first panel 1512 opposite to the magnetic source member 153 and the second panel 1514 opposite to the magnetic conduction plate 152, so as to use the support ribs 181 to abut against the magnetic source member 153 or the magnetic conduction plate 152, so that the magnetic conduction plate 152 is closely attached to the magnetic source member 153.

[0062] Middle limiting structures that cooperate with each other are also respectively provided in the middle parts of the first panel 1512 and the second panel 1514, so as to limit the distance between the first panel 1512 and the second panel 1514 through the middle limiting structures, and through holes are provided at the positions of the magnetic source member 153 and the magnetic conduction plate 152 corresponding to the respective middle limiting structures for the middle limiting structures to pass through.

[0063] A plurality of mutually cooperating circumferential side connection portions 163, 164 are respectively provided at positions of the first housing 151 and the second housing 154 adjacent to the peripheral wall, and middle limiting structures 161, 162 that cooperate with each other are also respectively provided in the middle parts of the first housing 151 and the second housing 154.

[0064] In an embodiment where the magnetic field module 150 is arranged as a square plate, the peripheral connecting portions 163, 164 include snap connection structures and / or screw connection structures provided at positions adjacent to the peripheral walls of the first housing 151 and the second housing 154. At positions near the edges of the four sides of the first housing 151, bayonets 164 are provided, and at positions near the edges of the four sides of the second housing 154, a snap connection structure of claws 163 that cooperate with the bayonets 164 is provided. That is, the peripheral connecting portion includes the bayonets 164 and the claws 163 that cooperate with them. Those skilled in the art can set various types of snap connection structures according to specific requirements for fixed connection. The peripheral connecting portions 163, 164 can ensure reliable connection and fixation of the periphery of the magnetic field module 150, and can reliably press the peripheries of the magnetic source member 153 and the magnetic conduction plate 152.

[0065] The magnetic field module 150 is long-term set in a low-temperature operating environment of refrigeration and freezing. Relying solely on the peripheral connecting portions 163, 164 cannot ensure that the encapsulation housing can integrally press the magnetic source member 153 and the magnetic conduction plate 152, which may cause local air pockets, thereby avoiding an increase in magnetic resistance in local areas and resulting in non-uniform magnetic fields.

[0066] In the field of magnetic fields, those skilled in the art generally believe that ensuring a uniform distribution of the magnetic field requires ensuring the integrity of the plate surface of the magnetic source member. However, in the magnetic field module 150 in this embodiment, the inventor creatively realizes that in the case of arranging the magnetic source member 153 and the magnetic conduction plate 152 simultaneously, the flatness of their fit has a greater impact on the magnetic field uniformity. In response to this situation, the inventor also tried to use an adhesive to paste the magnetic source member 153 and the magnetic conduction plate 152, but the thickness of the adhesive is difficult to control, and it will age after long-term use, and it is also difficult to achieve a flat fit between the magnetic source member 153 and the magnetic conduction plate 152.

[0067] Based on the above problems, this embodiment provides a central limiting structure that also cooperates with each other at the middle of the first housing 151 and the middle of the second housing 154. The central limiting structure may include: a first limiting portion 161 and a second limiting portion 162. The first limiting portion 161 is disposed on the inner surface of the first housing 151 and extends toward the second housing 154. The second limiting portion 162 is disposed at a position opposite to the first limiting portion 161 on the inner surface of the second housing 154, and the first limiting portion 161 and the second limiting portion 162 may be configured to be connected by a snap structure to limit the distance from the inner surface of the first housing 151 to the inner surface of the second housing 154. That is to say, the inner middle portions of the first housing 151 and the second housing 154 protrude relatively, cooperate with each other, and are connected by a snap structure at the ends. Through holes are provided at positions corresponding to the magnetic source member 153 and the magnetic conductive plate 152 and the corresponding central limiting structure for the central limiting structure to pass through. The central limiting structure can press the central regions of the magnetic source member 153 and the magnetic conductive plate 152, and cooperate with the peripheral connecting portions 163, 164 to achieve the overall tight fitting of the magnetic source member 153 and the magnetic conductive plate 152.

[0068] Support ribs 181 are provided in the area of the inner surface of the first housing 151 of the magnetic field module 150 that is opposite to the magnetic source member 153, and support ribs 181 are also provided in the area of the inner surface of the second housing 154 that is opposite to the magnetic conductive plate 152, so as to use the support ribs 181 to abut against the magnetic conductive plate 152 and the magnetic source member 153, making the magnetic conductive plate 152 and the magnetic source member 153 closely fit.

[0069] The support ribs 181 can be arranged in a ring shape around the central limiting structures 161, 162, and the minimum distance between adjacent support ribs 181 is set to be less than the sum of the thicknesses of the magnetic conductive plate 152 and the magnetic source member 153. That is, by restricting the density of the support ribs 181, it is ensured that there will be no hollowing at the positions of the distances between the support ribs 181. The width of the top surface of the support ribs 181 (as the contact surface that abuts against the magnetic conductive plate 152 or the magnetic source member 153) is set to be greater than the sum of the thicknesses of the magnetic conductive plate 152 and the magnetic source member 153. The support ribs 181 can also improve the structural strength of the packaging shell, and cooperate with the peripheral connecting portions 163, 164 and the central limiting structures 161, 162 to achieve the long-term stability of the structure. The above minimum distance between the support ribs 181 and the width of the top surface of the support ribs 181 are improvements made by the inventor through in-depth research on the structures and material properties of the magnetic conductive plate 152 and the magnetic source member 153. After physical verification of the samples, an unexpected effect is obtained, far exceeding the fitting effect when flatly abutting against the magnetic conductive plate 152 or the magnetic source member 153.

[0070] Thus, the self-structure of the support ribs 181 and their positions relative to each other are set according to the conditions of the magnetic conduction plate 152 and the magnetic source component 153. On the one hand, the structural strength and stability are improved, and on the other hand, reliable fitting between the magnetic conduction plate 152 and the magnetic source component 153 can be ensured.

[0071] The first panel 1512 of the first housing 151 is also provided with a positioning structure to limit the positions of the magnetic source component 153 and the magnetic conduction plate 152. Figure 5 FIG. 5 is a schematic view of the state of the first housing 151 of the magnetic field module 150 according to an embodiment of the present invention after installing the magnetic source component 153 and its partial enlarged view; Figure 6 FIG. 7 is a schematic view of the state of the first housing 151 of the magnetic field module 150 according to an embodiment of the present invention after installing the magnetic source component 153 and the magnetic conduction plate 152 and its partial enlarged view. The first panel 1512 abuts against the side of the magnetic source component 153 opposite to the magnetic conduction plate 152. The first panel 1512 is provided with a first positioning rib 173, and the magnetic source component 153 is arranged within the range defined by the first positioning rib 173. When the magnetic source component 153 is installed on the first panel 1512, the top of the first positioning rib 173 is flush with or lower than the top surface of the magnetic source component 153.

[0072] In some embodiments, the shape formed by the extension lines of the first positioning rib 173 is adapted to the outer peripheral contour of the magnetic source component 153, and the magnetic source component 153 is defined within the area formed by the extension lines of the first positioning rib 173. The height of the first positioning rib 173 is configured such that when the magnetic source component 153 is installed on the first panel, the top of the first positioning rib 173 is flush with or lower than the magnetic source component 153. The size of the magnetic conduction plate 152 is larger than that of the magnetic source component 153, and the above structure can avoid structural interference with the magnetic conduction plate 152.

[0073] The first panel 1512 is further provided with a second positioning rib 174 outside the first positioning rib 173. When the magnetic source component 153 is installed on the first panel 1512, the top of the second positioning rib 174 is higher than the top surface of the magnetic source component 153. That is to say, the height of the second positioning rib 174 can be configured such that when the magnetic source component 153 is installed on the first panel 1512, the top of the second positioning rib 174 is higher than the magnetic source component 153, and the shape formed by the extension lines of the second positioning rib 174 is adapted to the outer peripheral contour of the magnetic conduction plate 152, so as to define the magnetic conduction plate 152 within the area formed by the extension lines of the second positioning rib 174.

[0074] The magnetic source component 153 and the magnetic conduction plate 152 are generally square with one corner missing, and the shapes formed by the extension lines of the first positioning rib 173 and the second positioning rib 174 are also respectively set to be missing one corner, so as to avoid incorrect installation directions.

[0075] The installation process of the magnetic field module 150 is as follows: arrange the inner side of the first housing 151 upward; embed the magnetic source member 153 into the first positioning rib 173 on the inner surface of the first panel 1512 of the first housing 151, and then arrange the magnetic conduction plate 152 on the magnetic source member 153 to cooperate with the second positioning rib 174 on the inner surface of the first panel 1512. Snap the second housing 144 onto the first housing 141 to ensure reliable connection of the circumferential connection part and the middle limit structure. Finally, turn it over as a whole to obtain the second magnetic field module 150.

[0076] The magnetic field module 150 realizes the positioning and installation of two components with different sizes, namely the magnetic source member 153 and the magnetic conduction plate 152, through two positioning ribs with different heights.

[0077] Figure 7 FIG. is a schematic diagram of the magnetic field module 150 for a refrigerating and freezing storage device according to another embodiment of the present invention. Figure 8 is Figure 7 FIG. is an exploded view of the components of the magnetic field module 150 in the refrigerating and freezing storage device shown. This embodiment of the magnetic field module provides another fixed connection structure for the magnetic field module 150. A plurality of screw posts protrude from the inner side of the first housing 151 and serve as the middle limit structure and the circumferential connection part respectively. A plurality of screw holes are formed in the second housing 154, and the screws 155 pass through the screw holes and the screw posts to realize the connection and fixation of the first housing 151 and the second housing 154 and the height limit.

[0078] For example, when using a screw connection structure to realize the middle limit structure, the screw posts can be arranged on the inner surface of the first housing 151 or the second housing 154. The connecting screws are connected to the screw posts from the other side opposite to the screw posts to define the distance from the inner surface of the first housing 151 to the inner surface of the second housing 154. Similarly, by arranging screw posts at the positions near the edge of the magnetic field module 150 and using connecting screws for connection, the circumferential connection part can also be realized. The magnetic source member 153 and the magnetic conduction plate 152 can be provided with through holes at the positions where the screws 155 cannot be avoided for the screws 155 to pass through.

[0079] This embodiment also provides a refrigerating and freezing storage device 10.

Figure 12 FIG. is a schematic diagram of the installation state of the magnetic field module 150 in the refrigerating and freezing storage device 10 according to an embodiment of the present invention.

[0080] The refrigerating and freezing storage device 10 of this embodiment generally may include a box body 12, a door body 11, and a refrigeration system (not shown in the figure). At least one storage compartment 121 with an open front side may be defined within the box body 12, usually multiple, such as a refrigerated storage compartment, a frozen storage compartment, a variable-temperature storage compartment, etc. The specific number and functions of the storage compartments may be configured according to pre-set requirements. Figure 9 The refrigerating and freezing storage device 10 of the shown cross-opening refrigerator is only an example, and those skilled in the art can configure the specific number, functions, and layout modes of the storage compartments according to requirements. The storage compartment 121 may be spatially divided by means of a shelf, a partition board, a drawer, etc. to achieve corresponding storage functions, such as fresh-keeping, freezing, dry storage, etc. In some embodiments, one or more fresh-keeping storage containers 123 may be arranged within the storage compartment 121. The fresh-keeping storage effect is improved by applying a magnetic field inside the fresh-keeping storage container 123.

[0081] The fresh-keeping storage container 123 is arranged within the storage compartment 121 and may be a drawer-type storage container or a storage container of other structures. A magnetic field module 150 is provided on the inner side, outer side, or side wall of the fresh-keeping storage container 123.

[0082] Figure 13 FIG. 10 is a schematic diagram of a magnetic field installation structure 310 and its partial enlargement in the refrigerating and freezing storage device 10 with a magnetic field module according to an embodiment of the present invention. Opposite magnetic field installation structures 310 are provided on the side walls on both lateral sides of the storage compartment 121. Both sides of the magnetic field module 150 are respectively installed on the magnetic field installation structures 310 and are used to generate a magnetic field that promotes the formation of a fresh-keeping storage environment. In some embodiments, the magnetic field installation structure 310 is directly provided on the side wall of the inner liner of the box body or the vertical partition of the box body, that is, directly formed on the side wall of the storage compartment 121. In other embodiments, when the fresh-keeping storage container 123 is a drawer-type storage container, the magnetic field installation structure 310 may also be provided on the storage drawer slide rail device installed on the side wall of the inner liner of the box body or the vertical partition of the box body; that is to say, the magnetic field installation structure 310 is formed on the storage drawer slide rail device.

[0083] The magnetic field installation structure 310 may include: a chute 312 and a limiting component. The chute 312 may be arranged along the front-back direction of the box body 12, and the side part of the magnetic field module 150 is slidably arranged within the chute 312. That is to say, the chute 312 has an opening facing the inside of the storage compartment 121, and both side edges of the magnetic field module 150 are arranged within the chute 312. The limiting component is arranged on the bottom wall and / or side wall of the chute 312 and limits the position of the magnetic field module 150 relative to the chute 312 by abutting against the magnetic field module 150. When needed, the user can remove the magnetic field module 150 for cleaning.

[0084] The limiting component may include: a first limiting member 311, a second limiting member 312, and a limiting rib 313, which realize the limiting in multiple directions of the magnetic field module 150 and ensure the installation of the magnetic field module 150 in the correct position. The first limiting member 311 is arranged on the bottom wall of the chute 312 and is used to abut against the side of the magnetic field module 150. The first limiting member 311 may have a guiding surface that gradually protrudes towards the magnetic field module 150 from front to back, so as to gradually generate elastic deformation during the insertion process of the magnetic field module 150. That is to say, the guiding surface of the first limiting member 311 is inclined inwards from front to back, reducing the resistance during the insertion process of the magnetic field module 150, and applying limiting pressure from both sides after the magnetic field module 150 is installed in place.

[0085] In some embodiments, a plurality of first limiting members 311 are arranged in each chute 312. The plurality of first limiting members 311 are arranged at intervals along the front-back direction of the chute 312, applying more uniform limiting pressure. Figure 11 An embodiment with two first limiting members 311 at the front and back is shown. Those skilled in the art can, on this basis, set a greater number of first limiting members 311.

[0086] The second limiting member 312 is arranged on the upper side wall of the chute 312 and is used to abut against the magnetic field module 150 from the top of the magnetic field module 150. A limiting notch 1511 is also arranged at a position on the top wall of the magnetic field module 150 close to the side corresponding to the second limiting member 312, and is configured to accommodate the second limiting member 312 after the magnetic field module 150 is installed in the magnetic field installation structure 312 to realize limiting. The second limiting member 312 may have a guiding surface that gradually protrudes downward and obliquely from front to back, so as to gradually generate elastic deformation during the insertion process of the magnetic field module 150 and finally engage with the limiting notch 1511.

[0087] A limiting rib 313 is further arranged at the rear end of the chute 312. The limiting rib 313 is used to abut against the rear side of the magnetic field module 150, thereby limiting the front-back position of the magnetic field module 150.

[0088] The limiting components on both sides of the magnetic field module 150 can be symmetrically arranged. If the magnetic field module 150 is inserted wrongly or is inserted in the reverse direction itself, then it will be resisted or restricted by the limiting components, reminding the installer and enabling timely adjustment of the installation method.

[0089] Up to this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, however, without departing from the spirit and scope of the present invention, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
