Description

Technical Field

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

[0002] Refrigerators are one of the common household appliances. Foaming is an important part of refrigerator production. The foaming process involves injecting foaming materials between the outer shell and the inner tank of the refrigerator to achieve heat preservation of the refrigerator. Therefore, the quality of foaming directly determines the heat preservation performance and supporting strength of the refrigerator. With the development of refrigerators, large-volume refrigerators are becoming more and more popular, but as the volume increases, the size of the refrigerator is also getting larger, especially the foaming layer occupies more space.

[0003] In the related art, a vacuum insulation panel is used in the foam layer of the refrigerator to replace the foam material. The vacuum insulation panel has an extremely low thermal conductivity and a stronger heat preservation performance. By using a thinner vacuum insulation panel to replace the foam material, the thickness of the foam layer is reduced, the volume of the refrigerator is reduced, and the volumetric ratio and heat preservation of the refrigerator are improved.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Vacuum insulation panels are fragile products. They are easily damaged during actual transportation and operation, and have a high scrap rate. In addition, the cost of vacuum insulation panels is higher than that of foam materials. The high scrap rate directly increases the production cost of refrigerators.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0042] With the continuous improvement of living standards, refrigeration equipment such as refrigerators have been more and more widely used in consumers' daily lives, and consumers' requirements for the performance of refrigeration equipment are also constantly increasing. At present, in order to improve the thermal insulation effect of refrigeration equipment, thicker foaming materials are filled between the outer shell and the inner liner of the box to achieve thermal insulation of the refrigeration equipment. However, filling with thicker foaming materials will increase the volume of the refrigeration equipment and occupy a larger space. To solve this problem, in the related art, vacuum insulation panels (VIP) are set in the foaming layer of the refrigeration equipment, and vacuum insulation panels are used to replace part of the foaming material. The thermal conductivity of vacuum insulation panels is lower than that of traditional insulation materials, which can enhance the thermal insulation performance of the refrigeration equipment, and the vacuum insulation panels are relatively thin, which can reduce the space occupied by the refrigeration equipment.

[0043] Vacuum insulation panels are a type of vacuum insulation material. They are composed of a filling core material and a vacuum protective surface layer. They can effectively avoid heat transfer caused by air convection, so the thermal conductivity can be greatly reduced. The thermal conductivity of vacuum insulation panels can reach 0.002-0.004w / mk, which is 1 / 10 of the thermal conductivity of traditional insulation materials. Therefore, using vacuum insulation panels instead of foam materials can improve the thermal insulation performance of refrigeration equipment. The core material is the key factor that determines the thermal insulation performance of vacuum insulation panels. Common core materials include particle core materials, foam core materials, fiber core materials, and composite core materials. This also makes vacuum insulation panels fragile, especially the corners are extremely easy to damage. During actual transportation or installation, the scrap rate of vacuum insulation panels is high, which increases the production cost of refrigeration equipment.

[0044] Refrigeration equipment includes refrigerators, freezers, etc. Refrigeration equipment generally needs to undergo a foaming process to achieve its thermal insulation performance. Vacuum insulation panels can be used to replace part of the foaming materials in refrigerators and freezers. This embodiment takes a refrigerator as an example, and a vacuum insulation panel is set in the foaming layer of the refrigerator.

[0045] Combination Figures 1 to 6 As shown, a refrigerator provided by an embodiment of the present disclosure can protect the vacuum insulation panel in the foaming layer of the refrigerator and reduce damage to the vacuum insulation panel.

[0046] Optionally, combined Figures 1 to 3 As shown, the refrigerator includes an outer shell 10, an inner tank 20, a vacuum insulation panel assembly 30 and a protective member 40; the inner tank 20 and the outer shell 10 define a foaming cavity 21; the vacuum insulation panel assembly 30 is arranged in the foaming cavity 21; and the protective member 40 is arranged on the outer surface of the vacuum insulation panel assembly 30.

[0047] In the conventional refrigerator manufacturing process, a foaming material is injected into the foaming cavity 21 to fill the gap between the inner liner 20 and the outer shell 10, so that the refrigerator has heat preservation performance. At the same time, in order to improve the heat preservation performance of the refrigerator, the foaming material is usually filled thicker, which increases the space occupied by the refrigerator.

[0048] The vacuum insulation panel assembly 30 is arranged in the foaming cavity 21 to replace part of the foaming material. Since the vacuum insulation panel assembly 30 is thin, the volume of the refrigerator can be reduced. The vacuum insulation panel assembly 30 has a smaller thermal conductivity than the foaming material, thereby improving the heat preservation performance of the refrigerator.

[0049] A protective member 40 is provided on the outer surface of the vacuum insulation panel assembly 30, and the vacuum insulation panel assembly 30 is protected by the protective member 40, especially the corners of the vacuum insulation panel assembly 30 which are prone to collision. In this way, the vacuum insulation panel assembly 30 can be reduced from being touched by other objects or structures during transportation or installation, thereby enhancing the protection of the vacuum insulation panel assembly 30 and reducing the risk of damage to the vacuum insulation panel assembly 30.

[0050] Optionally, combined Figure 4 and Figure 5 As shown, the protective member 40 includes a first protective member 41 , and the first protective member 41 is provided with a hollow portion 4121 .

[0051] The vacuum insulation panel assembly 30 is arranged in the foaming cavity 21 and abuts against the outer shell 10. The foaming material fills the remaining space of the foaming cavity 21. The first protective member 41 is sleeved on the outer side of the vacuum insulation panel assembly 30 to protect the outer side of the vacuum insulation panel assembly 30. However, there may be gaps inside the vacuum insulation panel assembly 30, between the vacuum insulation panel assembly 30 and the outer shell 10, or between the vacuum insulation panel assembly 30 and the first protective member 41, which affects the thermal insulation performance. A hollow portion 4121 is provided in the first protective member 41 so that the foaming material is filled in the foaming cavity 21. If there is a gap, it can enter the first protective member 41 from the hollow portion 4121, so that the gaps that may exist inside the vacuum insulation panel assembly 30, between the vacuum insulation panel assembly 30 and the outer shell 10, or between the vacuum insulation panel assembly 30 and the first protective member 41 are filled with the foaming material, so that there is no gap in the foaming cavity 21, thereby ensuring the thermal insulation performance of the refrigerator. In addition, foam may be generated when the foaming material flows in the foaming cavity 21. By providing the hollow portion 4121, the foam can also be broken, and the foaming material flows more evenly in the foaming cavity 21, which is more conducive to sufficient foaming.

[0052] Optionally, combined Figure 6As shown, the first protection member 41 includes a side wall 411 and a bottom wall 412 , and the side wall 411 and the bottom wall 412 are connected, and the side wall 411 and the bottom wall 412 define an installation cavity, and at least a portion of the vacuum insulation panel assembly 30 is embedded in the installation cavity.

[0053] The vacuum insulation panel assembly 30 is in contact with both the side wall 411 and the bottom wall 412, so that the first protection member 41 is sleeved on the outside of the vacuum insulation panel assembly 30. The corners of the vacuum insulation panel assembly 30 and the corners of the first protection member 41 are mutually engaged, thereby protecting the outer side surface of the vacuum insulation panel assembly 30, especially the corners, from being touched, thereby reducing damage.

[0054] Optionally, the length and width of the first protective member 41 match the length and width of the vacuum insulation panel assembly 30, so that the vacuum insulation panel assembly 30 can be clamped in the first protective member 41, reducing the gap between the vacuum insulation panel assembly 30 and the first protective member 41 and affecting the thermal insulation performance.

[0055] Optionally, the bottom wall 412 is disposed opposite to the inner liner 20 , and the hollow portion 4121 is disposed on the bottom wall 412 .

[0056] The first protective member 41 is provided with a hollow portion 4121, and the foaming material is filled between the inner tank 20 and the bottom wall 412. The bottom wall 412 faces the foaming cavity 21, and the hollow portion 4121 is arranged on the bottom wall 412. This is conducive to the foaming material entering the first protective member 41 from the hollow portion 4121 to fill the gaps that may exist inside the vacuum insulation panel assembly 30, between the vacuum insulation panel assembly 30 and the outer shell 10, or between the vacuum insulation panel assembly 30 and the first protective member 41, so that the foaming is more uniform, thereby ensuring the thermal insulation performance of the refrigerator.

[0057] Optionally, the hollow portion 4121 is provided on the side wall 411 .

[0058] Optionally, the hollow portion 4121 is provided on the side wall 411 and the bottom wall 412 .

[0059] There is no specific restriction on the setting position of the hollow portion 4121. The hollow portion 4121 can be set on both the side wall 411 and the bottom wall 412, or only on the bottom wall 412. When there is a gap between the vacuum insulation panel assembly 30 and the first protective component 41, it is convenient for the foaming material to pass through the hollow portion 4121 into the first protective component 41 to fill the gap.

[0060] Optionally, the hollow portion 4121 includes circular holes sequentially arranged along the length direction and the width direction of the bottom wall 412 . The number of the circular holes is multiple and the multiple circular holes are arranged at intervals on the bottom wall 412 .

[0061] Optionally, the hollow portion 4121 can be a hole of other shapes or sizes such as a rectangle, so that when there is a gap between the vacuum insulation panel assembly 30 and the first protective member 41, the foaming material enters the first protective member 41 from the hollow portion 4121. The shape and size of the hollow portion 4121 are not specifically limited.

[0062] Optionally, combined Figure 4 As shown, the side of the vacuum insulation panel assembly 30 facing away from the bottom wall 412 abuts against the outer shell 10 .

[0063] The side of the vacuum insulation panel assembly 30 facing away from the bottom wall 412 is in contact with the outer shell 10, which can avoid a gap between the vacuum insulation panel assembly 30 and the outer shell 10 and affect the filling of the foaming material, thereby ensuring the heat preservation performance of the refrigerator.

[0064] Optionally, the side of the vacuum insulation panel assembly 30 facing away from the bottom wall 412 is connected to the housing 10 by gluing.

[0065] Connecting the vacuum insulation panel assembly 30 to the housing 10 by gluing can avoid gaps between the vacuum insulation panel assembly 30 and the housing 10. In addition, the vacuum insulation panel assembly 30 is a fragile product, and gluing can prevent the vacuum insulation panel assembly 30 from being damaged.

[0066] Optionally, the first protective member 41 is connected to the vacuum insulation panel assembly 30 by gluing, so that the first protective member 41 can be connected to the vacuum insulation panel assembly 30 to fix the first protective member 41. At the same time, the gluing method can reduce the gap between the first protective member 41 and the vacuum insulation panel assembly 30, and can also prevent the vacuum insulation panel assembly 30 from being broken due to connection with other connecting members.

[0067] It is understandable that the connection method between the first protective member 41, the vacuum insulation panel assembly 30 and the housing 10 is not limited to gluing, and may also be interference fit, magnetic fit, etc.

[0068] Optionally, the first protective member 41 is made of polypropylene (pp).

[0069] Polypropylene is a thermoplastic synthetic resin with excellent performance. It is a colorless, translucent, thermoplastic, lightweight general-purpose plastic with chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good high-wear resistance processing performance. It also has excellent mechanical properties, including tensile strength, compression strength and hardness, outstanding rigidity and bending fatigue resistance, and therefore, can provide good protection for the vacuum insulation panel assembly 30.

[0070] Optionally, combined Figure 4 and Figure 6As shown, the protection member 40 further includes a second protection member 42 . The second protection member 42 is disposed at the edge of the vacuum insulation panel assembly 30 and around the circumference of the vacuum insulation panel assembly 30 .

[0071] The second protection member 42 is disposed around the vacuum insulation panel assembly 30 to protect the periphery of the vacuum insulation panel assembly 30 from collision damage.

[0072] Optionally, the second protection member 42 is disposed between the first protection member 41 and the housing 10 , and abuts against both the first protection member 41 and the housing 10 .

[0073] The vacuum insulation panel assembly 30 is at least partially embedded in the first protective member 41, so that the bottom wall of the vacuum insulation panel assembly 30 abuts against the bottom wall 412 of the first protective member 41, and the bottom wall of the vacuum insulation panel assembly 30 is completely covered by the first protective member 41. However, the side wall of the vacuum insulation panel assembly 30 is at least partially covered by the first protective member 41, and a part of the side wall is not covered. By providing the second protective member 42, the second protective member 42 is surrounded by the vacuum insulation panel assembly 30 and is provided between the first protective member 41 and the outer shell 10, so that the vacuum insulation panel assembly 30 is embedded in the first protective member 41 and the second protective member 42. The first protective member 41, the second protective member 42 and the outer shell 10 jointly wrap the vacuum insulation panel assembly 30 to prevent the vacuum insulation panel assembly 30 from being hit during transportation and handling.

[0074] Optionally, the second protective member 42 is a buffer member.

[0075] The buffer member has a buffering and shock-absorbing performance. During the transportation or installation of the vacuum insulation panel assembly 30 , the second protective member 42 is provided to further enhance the protection of the vacuum insulation panel assembly 30 .

[0076] Optionally, the second protective member 42 is made of rubber.

[0077] The rubber material has high elasticity, which enhances the buffering and shock absorbing performance of the second protective member 42 .

[0078] Optionally, the second protection member 42 is tightly connected to the vacuum insulation panel assembly 30 by heat melting to enhance the reliability of the connection between the second protection member 42 and the vacuum insulation panel assembly 30 .

[0079] Optionally, the second protection member 42 is disposed around the vacuum insulation panel assembly 30 and at the bottom of the vacuum insulation panel assembly 30 to enhance the protection of the outer peripheral side of the bottom of the vacuum insulation panel assembly 30 .

[0080] Optionally, combined Figure 4 As shown, a first end surface 421 of the second protection member 42 facing the outer shell 10 is higher than a second end surface 321 of the vacuum insulation panel assembly 30 facing the outer shell 10 .

[0081] In this way, when the vacuum insulation panel assembly 30 is connected to the outer shell 10, the first end surface 421 is squeezed, so that the second protective component 42 is squeezed, and the second protective component 42 is tightly connected to the outer shell 10, which can not only play a role in buffering and shock absorption, reducing the collision damage of the vacuum insulation panel assembly 30, but also avoid the formation of gaps between the second protective component 42 and the outer shell 10 or between the vacuum insulation panel assembly 30 and the outer shell 10, thereby enhancing the thermal insulation performance.

[0082] Optionally, combined Figure 3 As shown, the housing 10 includes a first side wall 11 and a second side wall 12. The second side wall 12 is arranged opposite to the first side wall 11, and the inner liner 20 is arranged between the first side wall 11 and the second side wall 12. The first side wall 11 and the inner liner 20 define a first foaming cavity 211, and the second side wall 12 and the inner liner 20 define a second foaming cavity 212.

[0083] There are multiple vacuum insulation panel assemblies 30, and the multiple vacuum insulation panel assemblies 30 are respectively arranged in the first foaming cavity 211 and the second foaming cavity 212, which can simultaneously enhance the heat preservation performance of both sides of the refrigerator. In addition, the amount of foaming material injected into the first foaming cavity 211 and the second foaming cavity 212 can also be reduced at the same time to reduce the floor space on both sides of the refrigerator.

[0084] It is understandable that there is no specific limit to the number of vacuum insulation panel assemblies 30, and they can also be arranged between the rear wall of the refrigerator and the inner liner 20, or between the front wall of the refrigerator and the inner liner 20, and can be arranged according to actual installation requirements and production costs.

[0085] Optionally, the vacuum insulation panel assembly 30 includes a plurality of vacuum insulation panels sequentially arranged along a direction from the outer shell 10 to the inner liner 20 .

[0086] As the thickness of the vacuum insulation panel increases, the cost also gradually increases. Therefore, a plurality of relatively thin vacuum insulation panels are stacked on each other to increase the thickness of the vacuum insulation panel assembly 30. Compared with directly using thicker vacuum insulation panels, the cost can be controlled while increasing the thermal insulation performance. The thin vacuum insulation panels are more cost-effective.

[0087] Optionally, a plurality of vacuum insulation panels are stacked together by gluing to form a vacuum insulation panel assembly 30, which is disposed in the foaming cavity 21 of the refrigerator to enhance the heat preservation performance of the refrigerator.

[0088] Optionally, combined Figure 6 As shown, the vacuum insulation panel assembly 30 includes a first vacuum insulation panel 31 and a second vacuum insulation panel 32 .

[0089] Optionally, there is no specific limitation on the number and size of the vacuum insulation panels.

[0090] Exemplarily, the thickness of the first vacuum insulation panel 31 is 10 mm; the thickness of the second vacuum insulation panel 32 is 15 mm, and the first vacuum insulation panels 31 and the first vacuum insulation panels 31 are bonded together to form a vacuum insulation panel assembly 30 with a thickness of 25 mm.

[0091] The refrigerator provided by the embodiment of the present disclosure can achieve the following technical effects: the refrigerator includes an outer shell 10, an inner liner 20, a vacuum insulation panel assembly 30 and a protective member 40; the inner liner 20 and the outer shell 10 define a foaming cavity 21; the vacuum insulation panel assembly 30 is arranged in the foaming cavity 21; the protective member 40 is arranged on the outer surface of the vacuum insulation panel assembly 30, and the protective member 40 includes a first protective member 41 and a second protective member 42. The first protective member 41, the second protective member 42 and the outer shell 10 together wrap the vacuum insulation panel assembly 30 to strengthen the protection of the vacuum insulation panel assembly 30 and prevent the vacuum insulation panel assembly 30 from collision damage during transportation, use, etc. The vacuum insulation panel assembly 30 is composed of two relatively thin layers of vacuum insulation panels, which can reduce costs while enhancing the heat preservation performance of the refrigerator.
