Description

Technical Field

[0001] The invention relates to the technical field of refrigerators, and in particular to a refrigerator with convenient inner tank assembly. Background Art

[0002] The assembly of the horizontal freezer liner is a key link in the manufacturing process of the freezer, which directly affects the insulation effect and service life of the freezer. When assembling the box liner in the prior art, the box liner is usually first assembled on the box surface frame slot, and then the connection between the box liner and the box surface frame is wrapped and bonded with tape to fix. However, since the connection between the box surface frame and the box liner has an angle of nearly ninety degrees, and the tape needs to be wrapped around the corner, this will cause the box body to foam, because the tape is not pasted tightly, that is, it is not completely attached to the box surface frame and the box liner, there is a gap between the tape and the corner, and the gap cannot be filled with foaming liquid, which easily leads to delamination at the corner, affecting product quality. Summary of the invention

[0003] In view of this, the present invention provides a refrigerator that is convenient for assembling an inner liner without the need for fixing with tape in order to solve the above technical problems.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A refrigerator with convenient inner liner assembly comprises a box body and a door body rotatably connected to the box body, the box body comprises an outer box with an open top and an inner liner, and a box surface frame arranged on the top of the outer box and the inner liner, the inner liner is located inside the outer box, and a foaming gap is provided between the outer side wall of the inner liner and the inner side wall of the outer box, the tops of the outer box and the inner liner are both snapped onto the box surface frame, the top of the inner liner is provided with flanges perpendicular to the side walls of the inner liner, four card strips with card slots are provided on the box surface frame, two adjacent card strips are perpendicular to each other, and the flanges can be snapped into the card slots corresponding to the card strips.

[0006] In the above technical solution, the assembly process between the inner liner and the outer box is greatly simplified by designing a snap-in connection method in which the flanges around the top of the inner liner cooperate with the slots of the card strips on the box surface frame. This snap-in structure does not require complicated fixings, such as tape for wrapping and pasting or additional installation steps. The assembly can be completed by simply aligning the flange with the slot and snapping it in, which greatly improves production efficiency. Since there is no need for tape for pasting, there is no gap formed between the tape and the connecting corner between the box surface frame and the inner liner. The foaming liquid can also completely fill and support the inner liner, thereby eliminating the delamination phenomenon and improving product quality. In addition, the precise coordination of the card strip and the card slot ensures the accurate position of the inner liner in the box body, avoiding the problem of inner liner displacement or tilting due to manual installation errors. This not only improves the overall aesthetics of the freezer, but also ensures the uniformity and thermal insulation performance of the subsequent foaming process.

[0007] Furthermore, the length of the flange is smaller than the width of the inner container, and a first avoidance gap is provided between two adjacent flanges.

[0008] In the above technical solution, the design of the flange and the first avoidance notch can reduce the space occupied by the top edge of the inner liner, and at the same time it is more convenient for the assembly of the inner liner. Since the flange needs to be inserted into the slot by extrusion or the like, the independent design of each flange allows it to be assembled separately with the corresponding card strip, thereby improving the fault tolerance of the inner liner assembly.

[0009] Furthermore, at least one limiting rib is provided on the box surface frame, and the limiting rib is located at the first avoiding notch and matches the edge of the inner container.

[0010] In the above technical solution, the design of the limiting ribs significantly enhances the stability of the refrigerator structure. As an additional support point, the limiting ribs can effectively prevent the inner liner from displacement or deformation when subjected to external forces, ensuring the stability and reliability of the refrigerator in long-term use. In addition, the existence of the limiting ribs provides a clear positioning reference for the installation of the inner liner. During the assembly process, the operator can more easily align the edge of the inner liner with the limiting ribs to ensure the precise fit between the inner liner and the box frame.

[0011] Furthermore, the clamping strip is a structure with an "L"-shaped cross section, and the clamping strip and the bottom of the box surface frame together form the clamping groove, and a second avoidance gap is provided between two adjacent clamping strips.

[0012] In the above technical solution, the L-shaped card strip provides additional support surface and rigidity, so that the card slot can maintain a stable shape and position when subjected to the gravity or external force of the inner liner or other components, and is not easily deformed or damaged. At the same time, the L-shaped card strip also makes the opening of the card slot more spacious, which is convenient for the inner liner or other components to be installed to slide in easily. The second avoidance gap set between two adjacent card strips provides a certain amount of redundant space for the assembly of the inner liner flange, thereby making the assembly of the inner liner more convenient.

[0013] Furthermore, the inner liner includes a first plate body and a second plate body that are bent in one piece, and the first plate body and the second plate body are spliced ​​together to form a box-shaped structure with an open top.

[0014] In the above technical solution, dividing the inner liner into two parts for assembly can effectively reduce the deformation of the inner liner during assembly. The first plate body and the second plate body bent as one can reduce the number of seams between the plates, thereby reducing the structural weaknesses caused by improper seam treatment, ensuring that the structure of the inner liner has a certain strength, so that the inner liner can withstand greater pressure and impact, and extending the service life of the refrigerator.

[0015] Furthermore, the connecting ends of the first plate body and the second plate body are respectively provided with a first bending portion and a second bending portion folded in opposite directions, and the first bending portion and the second bending portion can be interlocked.

[0016] In the above technical solution, the design of the first bent portion and the second bent portion enables the two to interlock when connected, forming a mechanical locking effect, which not only enhances the stability of the connection, but also reduces the risk of loosening or falling off due to long-term use or external force, thereby ensuring the stability and durability of the inner liner structure. At the same time, it can also simplify the assembly of the inner liner. Just align the two and press lightly to achieve a quick and stable connection.

[0017] Furthermore, a plurality of first buckles are provided on one side of the box surface frame located at the foaming gap, and the plurality of first buckles are arranged at intervals.

[0018] In the above technical solution, the design of the first buckle can better fix the foaming material. When the foaming material is solidified, it can stably hook the solidified foaming material. It can not only serve as a fixing device during the foaming process to prevent the inner liner from moving and deforming, but also play a role in enhancing the structural strength after the foaming is completed.

[0019] Furthermore, a plurality of second buckles are provided on one side of the box surface frame located at the foaming gap, and the plurality of second buckles are all close to the edge of the box surface frame, and a plurality of grooves matching with the plurality of second buckles are provided on the inner side of the outer box.

[0020] In the above technical solution, the design of the second buckle and the groove simplifies the assembly process of the refrigerator. During the assembly process, the operator only needs to align the second buckle on the box frame with the groove on the inner side of the outer box, and then gently press to achieve a quick connection. This assembly method without additional fasteners or complex tools not only improves assembly efficiency, but also reduces assembly costs.

[0021] Furthermore, a plurality of ribs are provided on one side of the box surface frame located at the foaming gap, and the plurality of ribs are distributed in a ring shape and close to the inner side of the box surface frame.

[0022] In the above technical solution, the provision of the ribs can effectively prevent the leakage of the foaming liquid caused by the foaming material during the curing process, and can also significantly enhance the structural strength of the box surface frame, making it more stable and less prone to deformation when facing external pressure or impact.

[0023] Furthermore, a door seal is provided on one side of the door body close to the box body, and the door seal is arranged in a ring shape and close to the edge of the door body.

[0024] In the above technical solution, the design of the door seal effectively improves the sealing performance between the door body and the cabinet. When the door body is closed, the door seal can be tightly compressed between the door frame and the door body, forming an effective sealing barrier to prevent cold air from leaking out and outside air from invading, thereby maintaining the stability of the internal temperature of the refrigerator and the energy efficiency ratio.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0034] A preferred embodiment of the present invention is as follows.

[0035] Please refer to Figure 1-Figure 4A refrigerator convenient for assembling an inner liner 12 comprises a box body 1 and a door body 2 rotatably connected to the box body 1, the box body 1 comprises an outer box 11 with an opening at the top and an inner liner 12, and a box surface frame 13 arranged on the top of the outer box 11 and the inner liner 12, the inner liner 12 is located inside the outer box 11, and a foaming gap 14 is provided between the outer wall of the inner liner 12 and the inner wall of the outer box 11, the tops of the outer box 11 and the inner liner 12 are both snapped onto the box surface frame 13, the top of the inner liner 12 is provided with a flange 15 perpendicular to the side wall of the inner liner 12, the box surface frame 13 is provided with four card strips 131 with card slots, two adjacent card strips 131 are perpendicular to each other, and the flange 15 can be snapped into the card slot of the corresponding card strip 131.

[0036] This embodiment greatly simplifies the assembly process between the inner liner 12 and the outer box 11 by designing a snap-fitting method in which the flange 15 around the top of the inner liner 12 cooperates with the slot of the clip 131 on the box surface frame 13. This snap-fitting structure does not require complicated fixings, such as tape for wrapping and pasting or additional installation steps. The assembly can be completed by simply aligning the flange 15 with the slot and snapping it in, which greatly improves production efficiency. Since there is no need for tape for pasting, there is no gap formed between the tape and the connecting corner between the box surface frame 13 and the inner liner 12. The foaming liquid can also completely fill and support the inner liner 12, thereby eliminating the delamination phenomenon and improving product quality. In addition, the precise matching of the clip 131 and the slot ensures the accurate position of the inner liner 12 in the box body 1, avoiding the problem of displacement or tilt of the inner liner 12 caused by manual installation errors. This not only improves the overall aesthetics of the refrigerator, but also ensures the uniformity and thermal insulation performance of the subsequent foaming process.

[0037] It should be noted that the liner 12 is a flexible structure, and when the flange 15 is connected to the card slot, the flange 15 can be bent and squeezed so that it can be completely inserted into the card slot. Of course, after the liner 12 is assembled, the connection between the flange 15 and the card slot can be further adhered with tape. At this time, since the angle between the card strip 131 and the flange 15 has little effect and can be ignored, no large gap will be generated to affect the filling of the foam material.

[0038] In this embodiment, the length of the flange 15 is less than the width of the inner liner 12, and a first avoidance gap 151 is provided between two adjacent flanges 15. The inner liner 12 has four edges on its side surface, that is, the inner liner 12 has four sides and correspondingly has four flanges 15, and each flange 15 is independent and does not interfere with each other.

[0039] The design of the flange 15 and the first avoidance notch 151 of this embodiment can reduce the space occupied by the top edge of the inner liner 12, and also facilitates the assembly of the inner liner 12. Since the flange 15 needs to be inserted into the slot by extrusion or the like, the independent design of each flange 15 allows it to be assembled separately with the corresponding card strip 131, thereby improving the fault tolerance of the assembly of the inner liner 12.

[0040] Please refer to Figure 3 In this embodiment, at least one limiting rib 132 is provided on the box surface frame 13, and the limiting rib 132 is located at the first avoiding notch 151 and matches the edge of the inner container 12. Specifically, in this embodiment, four limiting ribs 132 are provided, corresponding to the four edges respectively.

[0041] The design of the limiting ribs 132 significantly enhances the stability of the refrigerator structure. As an additional support point, the limiting ribs 132 can effectively prevent the inner liner 12 from being displaced or deformed when subjected to external forces, thereby ensuring the stability and reliability of the refrigerator in long-term use. In addition, the existence of the limiting ribs 132 provides a clear positioning reference for the installation of the inner liner 12. During the assembly process, the operator can more easily align the edge of the inner liner 12 with the limiting ribs 132, ensuring the precise fit between the inner liner 12 and the box surface frame 13.

[0042] In this embodiment, the clamping strip 131 is an L-shaped structure in cross section, and the clamping strip 131 and the bottom of the box face frame 13 together form a clamping groove, and a second avoidance notch 133 is provided between two adjacent clamping strips 131. There are four clamping strips 131, and the four clamping strips 131 correspond to the four flanges 15 respectively, and the four clamping strips 131 are arranged in a square structure as a whole.

[0043] The L-shaped clamping strip 131 provides an additional support surface and rigidity, so that the clamping slot can maintain a stable shape and position when subjected to the gravity or external force of the inner liner 12 or other components, and is not easily deformed or damaged. At the same time, the L-shaped clamping strip 131 also makes the opening of the clamping slot more spacious, which is convenient for the inner liner 12 or other components to be installed to slide in easily. The second avoidance notch 133 set between two adjacent clamping strips 131 provides a certain amount of redundant space for the assembly of the flange 15 of the inner liner 12, thereby making it more convenient to assemble the inner liner 12.

[0044] Please refer to Figure 5 In this embodiment, the inner liner 12 includes a first plate body 121 and a second plate body 122 that are bent integrally, and the first plate body 121 and the second plate body 122 are spliced ​​together to form a box-shaped structure with an open top.

[0045] In this embodiment, the inner liner 12 is divided into two parts for assembly, which can effectively reduce the deformation of the inner liner 12 during assembly. The first plate 121 and the second plate 122 bent in one piece can reduce the number of seams between the plates, thereby reducing the structural weaknesses caused by improper seam treatment, ensuring that the structure of the inner liner 12 has a certain strength, so that the inner liner 12 can withstand greater pressure and impact, thereby extending the service life of the refrigerator.

[0046] Please refer to Figure 6 It should be noted that the connecting ends of the first plate body 121 and the second plate body 122 are respectively provided with a first bending portion 1211 and a second bending portion 1221 folded in opposite directions, and the first bending portion 1211 and the second bending portion 1221 can be interlocked.

[0047] The design of the first bend portion 1211 and the second bend portion 1221 enables the two to interlock when connected, forming a mechanical locking effect, which not only enhances the stability of the connection, but also reduces the risk of loosening or falling off due to long-term use or external force, thereby ensuring the stability and durability of the inner liner 12 structure. At the same time, it can also simplify the assembly of the inner liner 12. Just align the two and press lightly to achieve a quick and stable connection.

[0048] Please refer to Figure 7 In this embodiment, a plurality of first buckles 134 are provided on one side of the box face frame 13 located at the foaming gap 14, and the plurality of first buckles 134 are arranged at intervals. The design of the first buckle 134 can better fix the foaming material, and can stably hook the solidified foaming material after the foaming material is solidified, which can not only serve as a fixing device during the foaming process to prevent the inner liner 12 from moving and deforming, but also play a role in enhancing the structural strength after the foaming is completed.

[0049] In this embodiment, a plurality of second buckles 135 are provided on one side of the box surface frame 13 located at the foaming gap 14 . The plurality of second buckles 135 are all close to the edge of the box surface frame 13 , and a plurality of grooves matching with the plurality of second buckles 135 are provided on the inner side of the outer box 11 .

[0050] The design of the second buckle 135 and the groove simplifies the assembly process of the refrigerator. During the assembly process, the operator only needs to align the second buckle 135 on the box face frame 13 with the groove on the inner side of the outer box 11 and then gently press to achieve a quick connection. This assembly method without the need for additional fasteners or complex tools not only improves assembly efficiency, but also reduces assembly costs.

[0051] In addition, a plurality of ribs 136 are provided on one side of the box surface frame 13 located at the foaming gap 14, and the plurality of ribs 136 are distributed in a ring shape and close to the inner side of the box surface frame 13. The provision of the ribs 136 can effectively prevent the foaming liquid from leaking out during the curing process of the foaming material, and can also significantly enhance the structural strength of the box surface frame 13, making it more stable and less likely to deform when facing external pressure or impact.

[0052] In this embodiment, a door seal is provided on one side of the door body 2 close to the box body 1, and the door seal is arranged in a ring shape and close to the edge of the door body 2. The design of the door seal effectively improves the sealing performance between the door body 2 and the box body 1. When the door body 2 is closed, the door seal can be tightly compressed between the door frame and the door body 2, forming an effective sealing barrier to prevent cold air from leaking out and outside air from invading, thereby maintaining the stability of the internal temperature of the refrigerator and the energy efficiency ratio.
