Description

Technical Field

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

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common appliance used to preserve food or other items at low temperatures in life and is widely used in life and industry. With the rise of minimalist lifestyles, built-in home appliances have emerged. A built-in refrigerator is a type of refrigerator that mainly uses a refrigeration structure installed at the bottom of a cabinet to use the refrigeration structure and the cabinet as a whole as a refrigerator.

[0003] Most of the hinge assemblies of refrigerator doors in the related art are of a single-axis type, and the door body rotates around the hinge axis by cooperating with the hinge axis and the sleeve of the door body. When a refrigerator door body with this type of hinge assembly is opened, the corner of the refrigerator door body will extend beyond the side of the refrigerator body, thereby limiting the distance between the side of the built-in refrigerator and the cabinet. If a double-axis variable track hinge assembly is used, although the distance of the refrigerator door body extending beyond the side of the refrigerator body will be reduced, since the track of the double-axis variable track hinge is set on one part, the tracks are limited to avoid overlapping structures, and the refrigerator door body will still extend beyond the refrigerator body, and the problem of the refrigerator door body occupying the space on both sides of the refrigerator body when opening and closing still cannot be solved. Summary of the invention

[0007] The refrigerator hinge assembly can improve the structural space and structural reliability by arranging the main shaft on the hinge, the secondary slide groove on the hinge pad, and the secondary shaft and the main slide groove on the door pad. In the process of opening and closing the refrigerator door, the door pad can be controlled through the refrigerator door body to control the main shaft to slide in the main slide groove and the secondary shaft to slide in the secondary slide groove, thereby increasing the door opening angle and allowing the refrigerator door body to completely not extend beyond the two sides of the refrigerator body, thereby solving the problem of occupying the space on both sides of the refrigerator body when the refrigerator door body is opened and closed.

[0008] Optionally, a fixing hole is provided on a surface of the hinge close to the hinge pad, and a fixing pin is provided on a surface of the hinge pad close to the hinge, and the fixing hole is plugged into the fixing pin.

The secondary slide is an S-shaped structure, which can not only change the opening angle of the refrigerator door, but also make the refrigerator door smoother during opening and closing.

[0021] The cross-sections of the hinge gasket and the door gasket are rectangular, which can provide a larger contact area, enhance the stability of the connection, ensure that the refrigerator door is not easy to loosen or fall off during frequent opening and closing, and improve the reliability of the overall structure. The length of the hinge gasket is greater than the length of the door gasket, which helps to disperse stress and reduce wear caused by long-term use. The shaft hole is sleeved with the main shaft, which can simplify the installation process and increase the installation and disassembly speed of the refrigerator hinge assembly.

[0023] The hinge pad limits the sliding trajectory of the secondary shaft by reasonably arranging the sections of the secondary slide and the position of the shaft hole, thereby limiting the position and angle of the refrigerator. The first end of the first section of the secondary slide is arranged on the hinge pad close to the refrigerator door body and the side of the refrigerator body, which helps to improve the opening and closing stability of the refrigerator door body, reduce the shaking of the refrigerator door body during movement, and enhance the overall structural strength. The shaft hole is arranged on the hinge pad close to the second section of the secondary slide, which can ensure the accurate alignment of the main shaft and the secondary shaft, avoid usage problems caused by installation errors, and ensure the normal opening and closing of the refrigerator door. The first end of the third section of the secondary slide is arranged on the hinge pad away from the refrigerator door body, which helps to disperse stress and reduce wear during long-term use.

[0026] When the refrigerator door is in a closed state, the main shaft is located in the first section of the main slide;

[0027] When the refrigerator door is in an open state, the main axis is located at the connection between the first section of the main slide and the second section of the main slide.

[0028] Through the segmented design of the main slide, the refrigerator hinge assembly can operate more smoothly during the opening and closing of the refrigerator door, effectively reducing stress concentration, extending the service life, and improving the overall structural stability; the main slide with a smooth connection transition makes the refrigerator door smoother when opening and closing, reduces noise and vibration during operation, and thus makes the operation of the refrigerator quieter and more comfortable; the segmented design of the main slide can also limit the sliding trajectory of the main shaft, and then cooperate with the secondary slide and the secondary shaft to limit the position and angle of the refrigerator.

[0029] Optionally, the first section of the main chute and the second section of the main chute are both straight sections; and the angle between the first section of the main chute and the second section of the main chute is an obtuse angle.

[0030] The first section of the main slide and the second section of the main slide are both straight sections, which can ensure the stability of the refrigerator door during opening and closing, reduce the shaking of the refrigerator door during movement, and improve the stability and safety of use. The design of the line segment can also enhance the structural strength of the refrigerator hinge assembly, so that it can withstand greater weight and frequency of use.

DETAILED DESCRIPTION

[0044] The embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following embodiments do not represent all implementation methods consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application.

[0045] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common appliance used to preserve food or other items at low temperatures in life and is widely used in life and industry. With the rise of minimalist lifestyles, built-in home appliances have emerged. A built-in refrigerator is a type of refrigerator that mainly uses a refrigeration structure installed at the bottom of a cabinet to use the refrigeration structure and the cabinet as a whole as a refrigerator.

[0046] The hinge assembly of the refrigerator door in the relevant embodiments is mostly of a single-axis type, and the door body rotates around the hinge axis by cooperating with the hinge axis and the sleeve of the door body. When the refrigerator door body provided with this type of hinge assembly is opened, the corner of the refrigerator door body will extend beyond the side of the refrigerator body, thereby limiting the distance between the side of the built-in refrigerator and the cabinet. If a double-axis variable track hinge assembly is used, although the distance of the refrigerator door body extending beyond the side of the refrigerator body will be reduced, since the track of the double-axis variable track hinge is set on one part, the tracks are limited to avoid overlapping structures, and the refrigerator door body will still extend beyond the refrigerator body, and the problem of the refrigerator door body occupying the space on both sides of the refrigerator body when opening and closing still cannot be solved.

[0047] To solve the problem of the refrigerator door occupying the space on both sides of the refrigerator body when opening and closing, refer to Figure 1-Figure 7 Some embodiments of the present application provide a refrigerator hinge assembly, including: a hinge 1, a hinge gasket 2, and a door gasket 3; the hinge 1 is fixedly connected to the refrigerator body, the door gasket 3 is fixedly connected to the refrigerator door body, and the hinge gasket 2 is fixedly connected to the hinge 1; a main shaft 101 is provided on a surface of the hinge 1 close to the hinge gasket 2, a secondary slide groove 23 is provided on the hinge gasket 2, a main slide groove 31 is provided on the door gasket 3, and a secondary shaft 302 is provided on a surface of the door gasket 3 close to the hinge gasket 2, the main shaft 101 is slidably connected to the main slide groove 31, and the secondary shaft 302 is slidably connected to the secondary slide groove 23.

[0048] It should be understood that the material of the refrigerator hinge assembly can be selected from one or more of cold-rolled steel plate, aluminum alloy and zinc alloy. The cold-rolled steel plate has higher strength and hardness after cold rolling process, and can withstand larger torque and weight. This high strength makes the refrigerator hinge assembly not easy to deform or damage in long-term use, ensuring the stability and durability of the refrigerator door. The surface of the cold-rolled steel plate is smooth and flat, and it is easy to carry out rust-proof treatment such as galvanizing and spraying, thereby improving the rust and corrosion resistance of the refrigerator hinge assembly. Not only does it extend the service life of the refrigerator hinge assembly, but it also maintains the appearance of the refrigerator. Aluminum alloy has a lower density and higher strength, which can reduce the overall weight while ensuring the strength of the refrigerator hinge assembly, so as to reduce the burden and energy consumption of the refrigerator door. Aluminum alloy has good corrosion resistance and can maintain a long service life even in a humid environment. This makes the refrigerator hinge assembly particularly suitable for environments such as kitchens that may be exposed to moisture. Aluminum alloy has good plasticity and processing properties, and can be made into refrigerator hinge assemblies of various shapes by die casting, stamping, etc., which can meet the needs of different refrigerator designs. Zinc alloy has high strength and hardness, and can withstand certain torque and impact. Zinc alloy has excellent fluidity in the molten state, and is easy to fill the mold cavity and form complex shapes. This characteristic enables refrigerator hinge components to have high production efficiency and yield rate during the manufacturing process.

[0049] The main slide groove 31 can be a C-shaped structure, and the auxiliary slide groove 23 can be an S-shaped structure, which can not only change the opening angle of the refrigerator door, but also make the refrigerator door smoother during opening and closing.

[0050] The refrigerator hinge assembly can improve the structural space and structural reliability by arranging the main shaft 101 on the hinge 1, the secondary slide groove 23 on the hinge pad 2, and the secondary shaft 302 and the main slide groove 31 on the door pad 3. In the process of opening and closing the refrigerator door, the door pad 3 can be controlled through the refrigerator door body to control the main shaft 101 to slide in the main slide groove 31 and the secondary shaft 302 to slide in the secondary slide groove 23, thereby increasing the door opening angle and making the refrigerator door body completely within the two sides of the refrigerator body, so as to solve the problem of occupying the space on both sides of the refrigerator body when the refrigerator door body is opened and closed.

[0051] In addition, compared with a complex hinge structure, the refrigerator hinge assembly has the advantages of compact structure, simple assembly, low cost, and little impact on the original size of the refrigerator.

[0052] In some embodiments, a fixing hole 102 is provided on a surface of the hinge 1 close to the hinge pad 2 , and a fixing pin 202 is provided on a surface of the hinge pad 2 close to the hinge 1 , and the fixing hole 102 is plugged into the fixing pin 202 .

[0053] It should be understood that the cross-sections of the fixing hole 102 and the fixing pin 202 are both circular, and the circular cross-section design can evenly distribute the force and avoid sharp stress concentration at the connection point. The fixing hole 102 and the fixing pin 202 with a circular cross-section are also easy to align and insert, simplifying the installation process and improving assembly efficiency.

[0054] By plugging the fixing hole 102 with the fixing pin 202, not only can the structural stability between the hinge 1 and the hinge pad 2 be enhanced, ensuring that it is not easy to loosen or fall off during long-term use; it can also simplify the installation process of the refrigerator hinge assembly, reducing installation time and labor costs. In addition, the plug-in design makes it easier to disassemble the refrigerator hinge assembly when maintenance or replacement is required, reducing maintenance difficulty and cost; it enhances the overall durability of the refrigerator hinge assembly, reduces the failure rate caused by looseness or wear, effectively disperses stress, and improves the stability and reliability of the refrigerator hinge assembly during frequent switching.

[0055] In some embodiments, the hinge 1 is provided with a mounting hole, and the mounting hole is used to mount the hinge 1 on the refrigerator body. The mounting holes may be two, and the double-hole design can disperse the load and reduce the single-point force, thereby improving the strength and durability of the overall structure.

[0056] In some embodiments, the auxiliary slide 23 includes a first auxiliary slide section 231, a second auxiliary slide section 232 and a third auxiliary slide section 233; the first end of the first auxiliary slide section 231 is an arc-shaped structure, the second end of the first auxiliary slide section 231 is smoothly connected to the first end of the second auxiliary slide section 232, the second end of the second auxiliary slide section 232 is smoothly connected to the first end of the third auxiliary slide section 233, and the second end of the third auxiliary slide section 233 is an arc-shaped structure.

[0057] When the refrigerator door is in a closed state, the secondary shaft 302 is located in the first section 231 of the secondary slide; when the refrigerator door is in an open state, the secondary shaft 302 is located in the third section 233 of the secondary slide.

[0058] It should be understood that the cross section of the secondary shaft 302 is circular, and the widths of the secondary slot first section 231 , the secondary slot second section 232 , and the secondary slot third section 233 are the same and slightly larger than the diameter of the secondary shaft 302 .

[0059] Through the segmented design of the auxiliary slide groove 23, the refrigerator hinge assembly can operate more smoothly during the opening and closing of the refrigerator door, effectively reducing stress concentration, extending the service life, and improving the overall structural stability; the auxiliary slide groove 23 with a smooth connection transition makes the refrigerator door smoother when opening and closing, reduces noise and vibration during operation, and thus makes the operation of the refrigerator quieter and more comfortable; the segmented design of the auxiliary slide groove 23 can also limit the sliding trajectory of the secondary shaft 302, thereby limiting the position and angle of the refrigerator.

[0060] In some embodiments, the auxiliary chute 23 is an S-shaped structure, and the angle between the first section 231 of the auxiliary chute and the second section 232 of the auxiliary chute is an obtuse angle; the angle between the second section 232 of the auxiliary chute and the third section 233 of the auxiliary chute is an obtuse angle.

[0061] The angle between the first section 231 of the auxiliary chute and the second section 232 of the auxiliary chute is an obtuse angle; the angle between the second section 232 of the auxiliary chute and the third section 233 of the auxiliary chute is an obtuse angle, which can limit the opening angle of the refrigerator door and prevent the situation where the outer side of the refrigerator door exceeds the two sides of the refrigerator body due to excessive opening angle. The auxiliary chute 23 can be an S-shaped structure, which can not only change the opening angle of the refrigerator door, but also make the refrigerator door smoother during opening and closing.

[0062] In some embodiments, the auxiliary chute first section 231 and the auxiliary chute second section 232 are straight line sections, and the auxiliary chute third section 233 is an arc section.

[0063] The first section 231 of the auxiliary chute and the second section 232 of the auxiliary chute are straight sections, which can not only ensure the stability of the refrigerator door during opening and closing, reduce the shaking of the refrigerator door during movement, and improve the stability and safety of use; but also enhance the structural strength of the refrigerator hinge assembly, so that it can withstand greater weight and frequency of use. The combined design of straight sections and arc sections makes the refrigerator door smoother when opening and closing, and reduces noise and vibration during operation. This design can enhance the user experience and make the operation of the refrigerator quieter and more comfortable.

[0064] In some embodiments, the cross-sections of the hinge gasket 2 and the door gasket 3 are rectangular, and the length of the door gasket 3 is less than the length of the hinge gasket 2;

[0065] The hinge pad 2 is further provided with an axis hole 201 , which is a polygonal axis hole. The main shaft 101 is a cylindrical structure, and the axis hole 201 is sleeved with the main shaft 101 .

[0066] The cross-sections of the hinge gasket 2 and the door gasket 3 are rectangular, which can provide a larger contact area, enhance the stability of the connection, ensure that the refrigerator door is not easy to loosen or fall off during frequent opening and closing, and improve the reliability of the overall structure. The length of the hinge gasket 2 is greater than the length of the door gasket 3, which helps to disperse stress and reduce wear caused by long-term use. The shaft hole 201 is sleeved with the main shaft 101, which can simplify the installation process and increase the installation and disassembly speed of the refrigerator hinge assembly. The polygonal shaft hole 201 is combined with the cylindrical main shaft 101 to provide a stable connection and facilitate necessary adjustments and maintenance.

[0067] In some embodiments, the first end of the first section 231 of the auxiliary slide is arranged on the hinge pad 2 close to the refrigerator door body and the side of the refrigerator body; the axial hole 201 is arranged on the hinge pad 2 close to the second section 232 of the auxiliary slide; the first end of the third section 233 of the auxiliary slide is arranged on the hinge pad 2 away from the refrigerator door body.

[0068] It should be understood that the shortest distance from the position of the first end of the first section 231 of the secondary slide to the side of the refrigerator body is greater than or equal to the shortest distance from the edge of the refrigerator door away from the side of the refrigerator body to the side of the refrigerator body.

[0069] The hinge pad 2 limits the sliding track of the secondary shaft 302 by reasonably arranging the sections of the secondary slide 23 and the position of the shaft hole 201, thereby limiting the position and angle of the refrigerator. The first end of the first section 231 of the secondary slide is arranged on the hinge pad 2 near the refrigerator door body and the side of the refrigerator body, which helps to improve the opening and closing stability of the refrigerator door body, reduce the shaking of the refrigerator door body during movement, and improve the overall structural strength. The shaft hole 201 is arranged on the hinge pad 2 near the second section 232 of the secondary slide, which can ensure the accurate alignment of the main shaft 101 and the secondary shaft 302, avoid usage problems caused by installation errors, and ensure the normal opening and closing of the refrigerator door. The first end of the third section 233 of the secondary slide is arranged on the hinge pad 2 away from the refrigerator door body, which helps to disperse stress and reduce wear during long-term use.

[0070] In some embodiments, the main slide 31 includes a main slide first section 311 and a main slide second section 312; the first end of the main slide first section 311 is an arc-shaped structure, the second end of the main slide first section 311 is smoothly connected to the first end of the main slide second section 312, and the second end of the main slide second section 312 is an arc-shaped structure.

[0071] When the refrigerator door is in a closed state, the main shaft 101 is located at the first section 311 of the main slide; when the refrigerator door is in an open state, the main shaft 101 is located at the connection between the first section 311 of the main slide and the second section 312 of the main slide.

[0072] It should be understood that the cross section of the main shaft 101 is circular, and the widths of the first section 311 of the main slideway and the second section 312 of the main slideway are the same and slightly larger than the diameter of the main shaft 101 .

[0073] Through the segmented design of the main slide groove 31, the refrigerator hinge assembly can operate more smoothly during the opening and closing of the refrigerator door, effectively reducing stress concentration, extending the service life, and improving the overall structural stability; the main slide groove 31 with a smooth connection transition makes the refrigerator door smoother when opening and closing, reduces noise and vibration during operation, and thus makes the operation of the refrigerator quieter and more comfortable; the segmented design of the main slide groove 31 can also limit the sliding trajectory of the main shaft 101, and then cooperate with the secondary slide groove 23 and the secondary shaft 302 to limit the position and angle of the refrigerator.

[0074] In some embodiments, the first section 311 of the main slide and the second section 312 of the main slide are both straight sections; the angle between the first section 311 of the main slide and the second section 312 of the main slide is an obtuse angle.

[0075] The first section 311 of the main slide and the second section 312 of the main slide are both straight sections, which can ensure the stability of the refrigerator door during opening and closing, reduce the shaking of the refrigerator door during movement, and improve the stability and safety of use. The design of the line segment can also enhance the structural strength of the refrigerator hinge assembly, so that it can withstand greater weight and frequency of use. The angle between the first section 311 of the main slide and the second section 312 of the main slide is an obtuse angle, which can not only limit the opening angle of the refrigerator door, but also prevent the situation where the outer side of the refrigerator door exceeds the two sides of the refrigerator body due to excessive opening angle; it also makes the refrigerator door smoother when opening and closing, reduces noise and vibration during operation, improves the user experience, and makes the operation of the refrigerator quieter and more comfortable.

[0076] Some embodiments of the present application also provide a refrigerator, comprising a refrigerator body, a refrigerator door body and the refrigerator hinge assembly described in the above embodiments; the refrigerator hinge assembly is symmetrically arranged at both ends of the refrigerator door body; the hinge 1 of the refrigerator hinge assembly is fixedly connected to the refrigerator body, and the door gasket 3 of the refrigerator hinge assembly is fixedly connected to the refrigerator door body.

[0077] It should be understood that two of the refrigerator hinge assemblies may be installed on each of the refrigerator door bodies, and the two refrigerator hinge assemblies are symmetrically arranged at the upper and lower ends of the refrigerator door body.

[0078] Since the refrigerator has all the beneficial effects of the refrigerator hinge assembly described in the above embodiments, they are not described in detail here.
