Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] A freezer is a household or commercial appliance used to refrigerate or freeze food and items. It usually uses refrigeration technology to keep the temperature at a lower level to keep the food fresh and extend its shelf life.

[0003] In the existing refrigerator design, the box frame, the inner liner and the outer shell are the key components constituting the refrigerator body. However, there are some obvious problems and shortcomings in the current box frame structure and assembly method.

[0004] First, the traditional refrigerator box frame and the box shell are mainly connected by buckles. Although this assembly method is simple, it relies too much on the structural strength of the buckle. In the actual production, transportation and storage process, due to various factors, the buckle is easy to fail, resulting in inadequate connection. This will not only affect the sealing between the box frame and the box shell, but also increase the gap between the lap joints, which will lead to a series of problems such as foaming overflow and deformation of the box frame surface.

[0005] Secondly, the assembly of the box frame and the box liner is also a key link in the manufacturing process of the refrigerator. The existing assembly method mainly relies on the limiting effect of the box liner slot. However, this assembly method lacks sufficient stability in the vertical direction, which easily causes the box liner to fall off from the slot. In order to avoid this situation, the production line usually uses adhesive tape to fix it. Although this method can solve the problem to a certain extent, it greatly reduces production efficiency and increases the cost of auxiliary materials. Utility Model Content

[0006] The utility model solves one of the technical problems in the related art at least to a certain extent.

[0007] To this end, the present application aims to provide a refrigerator, in which the box frame and the shell are connected magnetically by means of magnetic suction parts. This magnetic suction connection method not only simplifies the assembly process and reduces the assembly steps, but also improves the stability and reliability of the connection. At the same time, the interval arrangement of the magnetic suction parts ensures the uniform distribution of the adsorption force, avoiding problems such as loose connection or deformation caused by uneven adsorption force.

[0008] In order to achieve the above object, the utility model provides a refrigerator, comprising:

[0009] A box frame, one side of which is provided with an annular first plug-in cavity and an annular second plug-in cavity, wherein the first plug-in cavity is sleeved with the second plug-in cavity;

[0010] A shell, wherein at least one end of the shell is open, a first flange is bent on one side of the opening of the shell, and the side of the shell provided with the first flange is used for being plugged into the first plug-in cavity;

[0011] A magnetic attraction member, the magnetic attraction member is attached to the first flange; and a plurality of the magnetic attraction members are spaced apart along the first flange ring direction; the magnetic attraction member is used to absorb the box frame;

[0012] The inner liner has at least one end that is open, and the open end of the inner liner is used for being plugged into the second plug-in cavity.

[0013] In the technical solution, the box frame and the shell are connected by magnetic suction parts. This magnetic suction connection method not only simplifies the assembly process and reduces the assembly steps, but also improves the stability and reliability of the connection. At the same time, the interval setting of the magnetic suction parts ensures the uniform distribution of the adsorption force, avoiding problems such as loose connection or deformation caused by uneven adsorption force.

[0014] In addition, the present application also provides a refrigerator, which includes:

[0015] A box frame, one side of which is provided with an annular first plug-in cavity and an annular second plug-in cavity, wherein the first plug-in cavity is sleeved with the second plug-in cavity;

[0016] A magnetic attraction member, the magnetic attraction member is arranged in the first plug-in cavity; and a plurality of the magnetic attraction members are arranged at intervals along the circumferential direction of the first plug-in cavity;

[0017] A shell, wherein at least one end of the shell is open, a first flange is bent on one side of the opening of the shell, and the side of the shell provided with the first flange is used for being plugged into the first plug-in cavity; the first flange is used for being adsorbed by the magnetic attraction member;

[0018] The inner liner has at least one end that is open, and the open end of the inner liner is used for being plugged into the second plug-in cavity.

[0019] In the technical solution, the box frame and the shell are connected by magnetic suction parts. This magnetic suction connection method not only simplifies the assembly process and reduces the assembly steps, but also improves the stability and reliability of the connection. At the same time, the interval setting of the magnetic suction parts ensures the uniform distribution of the adsorption force, avoiding problems such as loose connection or deformation caused by uneven adsorption force.

[0020] In some embodiments of the present application, the first flange extends toward the inner side of the shell, and the first flange is perpendicular to the corresponding side wall of the shell.

[0021] In the technical solution, the support area of ​​the first flange is increased so that it can better withstand the extrusion force from the box frame and the adsorption force of the magnetic suction piece. At the same time, the vertical flange design also makes the connection between the shell and the box frame tighter, reducing the risk of looseness or deformation caused by external forces.

[0022] In some embodiments of the present application, a threaded connector is provided on any side of the second plug-in cavity parallel to the depth direction of the inner liner opening, and an end of the threaded connector is used to press the inner liner against the opposite side wall.

[0023] In the technical solution, the end of the threaded connector can be rotated to press against the inner liner, thereby fixing the inner liner. This fixing method is not only easy to operate, but also has a reliable fixing effect. At the same time, the design of the threaded connector also has a certain adjustment range, which can be fine-tuned according to the actual size of the inner liner to ensure the stability and sealing of the fixation.

[0024] In some embodiments of the present application, a baffle is provided in the second plug-in cavity, the baffle is provided between the threaded connector and the inner liner, the threaded connector is used to abut against the baffle, and the baffle is used to fit the inner liner.

[0025] In the technical solution, the presence of the baffle not only increases the stability of the inner liner fixation, but also protects the inner liner, avoiding possible damage caused by the direct action of the threaded connector on the inner liner.

[0026] In some embodiments of the present application, a second flange is bent on one side of the inner liner that is inserted into the second insertion cavity. When the second flange is squeezed by the threaded connector, deformation occurs between the second flange and the corresponding side wall of the inner liner.

[0027] In the technical solution, when the threaded connector is squeezed, deformation occurs between the second flange and the corresponding inner liner side wall. This deformation not only increases the sealing between the inner liner and the box frame, but also enables the inner liner to have a certain buffering capacity when subjected to external force, reducing the risk of damage caused by external force impact. In addition, a certain amount of rebound occurs between the second flange and the inner liner, thereby increasing the pressing force between the threaded connector and the second plug-in cavity side wall, thereby improving the sealing performance and connection strength.

[0028] In some embodiments of the present application, the first plug-in cavity is composed of at least three first plug-in sections, the first flange is composed of multiple first bending sections, and the number of the first plug-in sections and the first bending sections are the same and are arranged in one-to-one correspondence.

[0029] In the technical solution, it is ensured that the housing can be fully inserted into the first plug-in cavity.

[0030] In some embodiments of the present application, the number of the magnetic elements is the same as the number of the first bending sections and are arranged in a one-to-one correspondence.

[0031] In the technical solution, it is ensured that each bending section can be effectively adsorbed by the magnetic adsorption component, thereby achieving a uniform connection between the housing and the box frame. In addition, the adsorption force can fully act on the bending section, thereby improving the stability and reliability of the connection.

[0032] In some embodiments of the present application, the length direction of the magnetic attraction component is arranged along the length direction of the corresponding first bending section.

[0033] In the technical solution, this design not only increases the contact area between the magnetic element and the first bending section, increases the adsorption force, but also makes the adsorption force distribution more uniform, avoiding problems such as loose connection or deformation caused by uneven adsorption force. At the same time, this design is also conducive to the installation and disassembly of the magnetic element, improving the convenience of assembly and maintenance.

[0034] In some embodiments of the present application, the second plug-in cavity is flared in the direction toward the inner container.

[0035] In the technical solution, the expansion is used for guidance, so that the inner liner is easily inserted into the second plug-in cavity, thereby improving the installation efficiency.

[0036] In some embodiments of the present application, a third plug-in cavity is also provided on one side of the box frame having the first plug-in cavity, the second plug-in cavity is sleeved with the third plug-in cavity, and the third plug-in cavity is used to install a light strip.

[0037] In the technical solution, this design not only reasonably utilizes the space of the box frame, but also facilitates the installation of the light strip. By installing the light strip in the third plug-in cavity, the lighting function inside the refrigerator can be easily realized, which improves the practicality and user experience of the refrigerator. At the same time, the installation position of the light strip can also be adjusted as needed to adapt to different refrigerator structures and usage scenarios.

This magnetic connection method not only simplifies the assembly process and reduces the assembly steps, but also improves the stability and reliability of the connection.

In addition, the present application also provides a refrigerator, which includes: a box frame 100, a magnetic attraction part 300, an outer shell 200 and an inner liner 400; wherein, a first annular plug-in cavity 101 and a second annular plug-in cavity 102 are opened on one side of the box frame 100, wherein the first plug-in cavity 101 is sleeved with the second plug-in cavity 102.

[0077] The magnetic member 300 is disposed in close contact with the first plug-in cavity 101 ; and a plurality of magnetic members 300 are disposed at intervals along the circumferential direction of the first plug-in cavity 101 .

[0078] At least one end of the shell 200 is open, and a first flange 201 is bent on one side of the opening of the shell 200. The side of the shell 200 with the first flange 201 is used to be plugged into the first plug-in cavity 101; the first flange 201 is used to be adsorbed by the magnetic attraction component 300.

[0079] At least one end of the inner liner 400 is open, and the open end of the inner liner 400 is used to be plugged into the second plug-in cavity 102 .

[0080] Through the above solution, the box frame 100 and the housing 200 are magnetically connected through the magnetic member 300. This magnetic connection method not only simplifies the assembly process and reduces the assembly steps, but also improves the stability and reliability of the connection. At the same time, the interval setting of the magnetic member 300 ensures the uniform distribution of the adsorption force, avoiding problems such as loose connection or deformation caused by uneven adsorption force.

[0081] In some embodiments, the housing 200 is in a rectangular shape, and the box frame 100 is in a rectangular frame shape.

[0082] In some embodiments, the first plug-in cavity 101 is composed of at least three first plug-in sections, the first flange 201 is composed of a plurality of first bending sections, and the number of the first plug-in sections and the first bending sections are the same and are arranged in one-to-one correspondence.

[0083] In some embodiments, there are four first plug-in sections, and two of them are parallel.

[0084] In some embodiments, the length direction of the first bending section is the same as that of the corresponding first plug section, thereby ensuring that the housing 200 can be fully inserted into the first plug cavity 101 .

[0085] In some embodiments, the number of magnetic elements 300 is the same as the number of first bending segments and they are arranged in one-to-one correspondence. This ensures that each bending segment can be effectively adsorbed by the magnetic element 300, thereby achieving a uniform connection between the housing 200 and the box frame 100. This also enables the adsorption force to fully act on the bending segment, thereby improving the stability and reliability of the connection.

[0086] In some embodiments, the length direction of the magnetic member 300 is arranged along the length direction of the corresponding first bending section. This design not only increases the contact area between the magnetic member 300 and the first bending section, increases the adsorption force, but also makes the adsorption force distribution more uniform, avoiding problems such as loose connection or deformation caused by uneven adsorption force. At the same time, this design is also conducive to the installation and disassembly of the magnetic member 300, improving the convenience of assembly and maintenance.

[0087] In some embodiments, the magnetic member 300 is bonded to the corresponding first bending section.

[0088] In some embodiments, the magnetic member 300 is connected to the corresponding first bending section by bolts.

[0089] In some embodiments, the magnetic member 300 is connected to the corresponding first bending section via screws.

[0090] In some embodiments, the box frame 100 can be adsorbed by a suction member.

[0091] It is understandable that the box frame 100 is made of a material that can be adsorbed by the magnetic element 300 .

[0092] In some embodiments, the box frame 100 is made of metal.

[0093] In some embodiments, the first flange 201 extends toward the inner side of the housing 200, and the first flange 201 is perpendicular to the corresponding side wall of the housing 200. The support area of ​​the first flange 201 is increased, so that it can better withstand the extrusion force from the box frame 100 and the adsorption force of the magnetic element 300. At the same time, the vertical flange design also makes the connection between the housing 200 and the box frame 100 tighter, reducing the risk of looseness or deformation caused by external force.

[0094] In some embodiments, the housing 200 includes at least four surfaces. For example, both ends of the housing 200 are open. The four first bending sections are respectively arranged on the four surfaces of the housing 200 facing the box frame 100 .

[0096] In some embodiments, the magnetic member 300 is parallel to the first flange 201 .

[0097] In some embodiments, the magnetic member 300 is parallel to the inner bottom wall of the first insertion cavity 101. When the first flange 201 is inserted into the first insertion cavity 101 to connect the housing 200 to the box frame 100, the magnetic member 300 is clamped between the first flange 201 and the inner bottom wall of the first insertion cavity 101.

[0098] In some embodiments, the first insertion cavity 101 is directly opened in the box frame 100 .

[0099] In some embodiments, the first insertion cavity 101 is formed between two outwardly protruding edges of the box frame 100 .

[0100] In some embodiments, a threaded connector 500 is provided on any side of the second plug-in cavity 102 parallel to the depth direction of the opening of the liner 400, and the end of the threaded connector 500 is used to press the liner 400 against the opposite side wall.

At the same time, the design of the threaded connector 500 also has a certain adjustment range, which can be fine-tuned according to the actual size of the liner 400 to ensure the stability and sealing of the fixation.

[0101] In some embodiments, the second insertion cavity 102 is directly opened in the box frame 100 .

[0102] In some embodiments, the second insertion cavity 102 is formed between two outwardly protruding edges of the box frame 100 .

[0103] In some embodiments, the threaded connector 500 is vertically disposed and threadedly connected to a side of the second plug-in cavity 102 facing the first plug-in cavity 101. The threaded connector 500 can be hidden between the outer shell 200 and the inner liner 400 to improve the aesthetics.

[0105] In some embodiments, a plurality of threaded connectors 500 are arranged at intervals along the circumference of the second insertion cavity 102 , thereby further improving the connection strength between the box frame 100 and the inner container 400 .

[0106] In some embodiments, a threaded hole is formed through the side wall of the second plug-in cavity 102 , and the threaded hole is used for the threaded connector 500 to pass through and be threadedly connected.

[0107] In some embodiments, the number of threaded connectors 500 may be less than the number of threaded holes.

[0108] In some embodiments, a baffle 600 is disposed in the second plug-in cavity 102, and the baffle 600 is disposed between the threaded connector 500 and the liner 400. The threaded connector 500 is used to abut against the baffle 600, and the baffle 600 is used to fit the liner 400. The existence of the baffle 600 not only increases the stability of the fixation of the liner 400, but also protects the liner 400, avoiding possible damage caused by the threaded connector 500 directly acting on the liner 400.

[0109] In some embodiments, one baffle 600 may correspond to one threaded connector 500 .

[0110] In some embodiments, one baffle 600 may correspond to multiple threaded connectors 500 .

[0111] In some embodiments, the baffle 600 is a half strip of galvanized material. That is, a galvanized layer is provided on one side of the baffle 600. Galvanizing forms a hard and durable outer film on the surface of the baffle 600, which improves the hardness and strength of the baffle 600 and makes the baffle 600 more wear-resistant. In addition, the galvanized baffle 600 will also be softer during bending, stretching, etc., reducing the loss of steel and thus extending the service life. It also improves the corrosion resistance of the baffle 600.

[0112] In some embodiments, the magnetic attraction member 300 may be a magnet.

[0113] In some embodiments, the magnetic attraction member 300 may be a magnet.

[0114] In some embodiments, the magnetic attraction member 300 may be an electromagnet.

[0115] In some embodiments, the threaded connector 500 may be a bolt.

[0116] In some embodiments, the threaded connector 500 may be a screw.

[0117] In some embodiments, the threaded connector 500 may be a screw.

[0118] In some embodiments, the inner liner 400 is inserted into the second plug-in cavity 102 and bent with a second flange. When the second flange is squeezed by the threaded connector 500, deformation occurs between the second flange and the corresponding side wall of the inner liner 400. When the threaded connector 500 is squeezed, deformation occurs between the second flange and the corresponding side wall of the inner liner 400. This deformation not only increases the sealing between the inner liner 400 and the box frame 100, but also enables the inner liner 400 to have a certain buffering capacity when subjected to external force, thereby reducing the risk of damage caused by external force impact. In addition, a certain rebound will be generated between the second flange and the inner liner 400, thereby increasing the pressing force between the threaded connector 500 and the side wall of the second plug-in cavity 102, thereby improving the sealing performance and connection strength.

[0119] In some embodiments, the second insertion cavity 102 is composed of at least three second insertion sections, the second flange is composed of a plurality of second bending sections, and the number of the second insertion sections and the second bending sections are the same and are arranged in one-to-one correspondence.

[0120] In some embodiments, the minimum angle between the second bending section and the side corresponding to the inner liner 400 is less than 90°.

[0121] In some embodiments, the threaded connector 500 may abut the liner 400 .

[0122] In some embodiments, the threaded connector 500 may abut against the second bending segment.

[0123] In some embodiments, when the threaded connector 500 abuts the inner liner 400 or the second bending section, the angle between the second bending section and the corresponding side wall of the inner liner 400 is reduced, thereby increasing the clamping force between the threaded connector 500 and the side wall of the second plug-in cavity 102, thereby improving the sealing performance and connection strength.

[0124] In some embodiments, the second inserting cavity 102 is expanded in the direction toward the inner liner 400. The expansion is used for guidance, so that the inner liner 400 is easily inserted into the second inserting cavity 102, thereby improving installation efficiency.

[0125] In some embodiments, two parallel side walls of the second inserting cavity 102 that are opposite to each other and close to the opening of the second inserting cavity 102 are inclined in directions away from each other.

[0126] In some embodiments, two edges of the opening of the second inserting cavity 102 are respectively provided with a first guide surface and a second guide surface. The first guide surface and the second guide surface are inclined from a direction away from each other to a side facing the inner container 400.
