Detailed implementation manners

[0025] As Figure 1 , Figure 4 and Figure 6 shown, a freezer is shown, which includes a cabinet opening part 1 and an inner liner 2. The cabinet opening part 1 has two layers of limit walls 11, an inner layer and an outer layer. There is a limit groove between the two layers of limit walls 11. The inner liner 2 is clamped in the limit groove. The limit wall 11 on the outer side is bent inward to form a guide structure 111.

[0026] It should be noted that the "inner" mentioned above refers to the position close to the internal space 113 of the refrigerator, and the "outer" refers to the position far from the internal space 113 of the refrigerator. Specifically, Figure 1 and Figure 4 what is seen in is the limit wall 11 on the outer side. As Figure 6 shown, the limit wall 11 includes an outer wall 11A on the outer side and an inner wall 11B on the inner side.

[0027] Preferably, the guide structure 111 is formed by bending. The guide structure 111 and the cabinet opening part 1 are integrally designed, which enhances the strength and stability of the structure, making the freezer more durable and safe.

[0028] The setting of the guide structure 111 can also ensure the correct insertion of the inner liner 2, avoid dislocation or instability, and improve the convenience and stability of use.

[0029] Furthermore, the guide structure 111 has a first thickness. The thickness of the guide structure 111 is thicker than that of the traditional guide rib. Here, the thickness refers to the dimension along the length direction of the limit groove, which is more convenient to realize the guiding function. The increase in thickness is not easy to damage the inner liner 2, effectively solving the problems of inconvenient installation and easy scratching of the cabinet opening when the inner liner 2 made of metal material is inserted into the limit groove. If the cabinet opening is scratched and there is a large gap, it will lead to poor sealing effect at the cabinet opening, easy overflow of the foaming material when the box is filled with foaming material, and a high rejection rate.

[0030] Further, there are multiple guiding structures 111 on the outer limiting wall. There is an outer end portion 112 between two adjacent guiding structures 111. Both ends of the guiding structure 111 are respectively connected to the two outer end portions 112. The guiding structure 111 is bent inward relative to the outer end portion 112 to form an internal space 113. Specifically speaking, the internal space 113 is formed by the outer end portions 112 and the guiding structures 111 at both ends. The internal space 113 is the space yielded by the guiding structure 111 bending inward relative to the outer end portion 112. One end of the guiding structure 111 close to the notch of the limiting groove has an outer edge portion 111a flush with the outer end portion 112.

[0031] The arrangement of the outer end portion 112 highlights the guiding structure 111, making the guiding structure 111 well - spaced. The lower ends of the outer end portion 112 and the guiding structure 111 are respectively connected to the bottom of the cabinet - mouth member 1, achieving a multi - level supporting effect, which can enhance the stability and reliability of the cold cabinet structure, ensure that the inner liner 2 is firmly installed in the limiting groove, and avoid movement and shaking.

[0032] Further, there is a guiding structure 111 between every two adjacent outer end portions 112 on the outer side wall 11A; there is an outer end portion 112 between every two adjacent guiding structures 111 on the outer side wall 11A. The outer end portion 112 and the guiding structure 111 are alternately arranged, enhancing the stability and durability of the overall structure, ensuring that the cold cabinet will not loosen or shift during long - term use, and improving the service life of the product.

[0033] Further, both ends of the guiding structure 111 are respectively connected to the adjacent outer end portions 112, making the outer side wall 11A form a whole. The outer side wall 11A with an integrated structure has better strength.

[0034] As Figure 6 shown, the guiding structure 111 is bent inward relative to the outer end portion 112 to form the internal space 113. The setting of the internal space 113 saves materials and is more beautiful.

[0035] At the same time, since the outside of the guiding structure 111 is the internal space 113, that is, a certain space for tolerance or deformation is given. When the guiding structure 111 cannot hold the inner liner 2, the guiding structure 111 can be bent or deformed towards the direction of the internal space 113 to yield a part of the space, making it more convenient and smooth for the inner liner 2 to be inserted into the limiting groove, not easily blocked or stuck, and making the installation of the inner liner 2 more simple and efficient.

[0036] The design of the outer edge portion 111a can ensure that the inner liner 2 is correctly inserted into the limiting groove, avoid dislocation or inaccurate mating position, and improve the firm connection and safety between the inner liner 2 and the cold cabinet.

[0037] Furthermore, an observation groove 112a is provided on the outer wall 11A. The setting of the observation groove 112a can help workers observe the position of the inner liner 2 inserted into the limit groove, ensure the correct fit between the inner liner 2 and the cabinet opening 1, avoid incorrect installation or looseness, and improve the accuracy and stability of the installation.

[0038] The observation slot 112a is arranged on the outer end portion 112, which improves the convenience of operation for workers, allowing workers to easily observe the position of the inner liner 2 inserted into the limit slot without the need for additional tools or operations, thereby improving the convenience of operation for workers.

[0039] The worker can clearly see the insertion depth and position of the inner liner 2 through the observation slot 112a, which facilitates the worker to make adjustments and confirmations, thereby improving the convenience of use and the accuracy of operation.

[0040] The provision of the observation slot 112a enables workers to observe the position of the inner tank 2 at any time, which facilitates maintenance and cleaning work and also ensures the hygiene and cleanliness of the interior of the refrigerator.

[0041] Furthermore, the observation groove 112a is provided on the outer end portion 112, and the observation groove 112a is opened from the groove opening of the limiting groove to the groove bottom of the limiting groove. The depth of the observation groove 112a corresponds to the preset insertion depth of the inner liner 2.

[0042] Furthermore, the guide structure 111 includes a bending portion 111b and a vertical portion 111c, one end of the bending portion 111b is close to the slot of the limiting slot, and the other end of the bending portion 111b is connected to the vertical portion 111c. The bending portion 111b is bent and gradually approaches the limiting wall 11 located on the inner side from one end of the bending portion 111b to the other end.

[0043] See also Figure 6 The outer edge portion 111a, the bent portion 111b and the vertical portion 111c are connected in sequence from the limit groove opening to the limit groove bottom.

[0044] From the limit groove mouth to the limit groove bottom, the bent portion 111b gradually approaches the limit wall 11. This design increases the firmness and stability of the structure, ensuring that the inner liner 2 gradually penetrates into the limit groove during the installation process and is finally fixed in the limit groove, supported by the vertical portion 111c and the inner wall 11B to prevent movement and shaking.

[0045] The design of the bent portion 111b and the vertical portion 111c allows the bent portion 111b to gradually approach the limiting wall 11, ensuring a close fit between the guide structure 111 and the limiting groove, thereby enhancing the fixation of the inner liner 2 and reducing the displacement of the inner liner 2 caused by vibration or external force, making the installation of the inner liner 2 more convenient and quick, and workers can easily insert and fix the inner liner 2 in the correct position.

[0046] See alsoFigures 2 - 5 , the card slot hole 111d is opened on the vertical portion 111c, and the card slot hole 111d penetrates through the vertical portion 111c. A hook portion 21 that cooperates with the card slot hole 111d is provided on the inner container 2. It should be noted that, as Figure 4 shown, the penetration here means penetration along the inside-outside direction.

[0047] The cooperative design of the card slot hole 111d and the hook portion 21 ensures that the inner container 2 can be accurately and stably installed in the limit slot, avoiding displacement or loosening caused by vibration or external force, and improving the stability of the freezer. The card slot hole 111d is designed to be a through type, making the connection between the inner container 2 and the guiding structure 111 more firm and reliable, reducing the risk of the inner container 2 falling off or being unstable, and improving the safety of the freezer. The design of the card slot hole 111d and the hook portion 21 enables workers to easily insert or remove the inner container 2, making the operation more convenient and saving the time and cost of installation and maintenance. The setting of the card slot hole 111d makes the connection between the guiding structure 111 and the inner container 2 closer, enhancing the stability of the structure, ensuring that the inner container 2 is fixed in the correct position, and reducing the problems caused by movement during use.

[0048] Furthermore, there are multiple connected or separated limit slots on the cabinet mouth member 1. Each limit wall 11 forming each limit slot has at least one observation slot 112a and one card slot hole 111d. Specifically, at least one observation slot 112a and one card slot hole 111d are provided on the outer side wall 11A of each limit wall 11 forming each limit slot.

[0049] The limit slots are for adapting to the installation of the inner container 2, and their connection or separation is determined according to specific installation requirements. However, at least one observation slot 112a on each outer side wall 11A is for facilitating the observation of the cooperation degree between the inner container 2 and the cabinet mouth member 1 at this limit slot. So that the cooperation between the inner container 2 and the cabinet mouth member 1 in each limit slot can be conveniently observed by workers. At least one card slot hole 111d on each outer side wall 11A is to control the stable connection between the inner container 2 and the cabinet mouth member 1 in each limit slot.

[0050] Furthermore, on the limit wall 11 forming the same limit slot, specifically on the outer side wall 11A forming the same limit slot, there is at least one guiding structure 111 without a card slot hole 111d between the observation slot 112a and the card slot hole 111d.

[0051] There is at least one guiding structure 111 without a card slot hole 111d between the observation slot 112a and the card slot hole 111d, which helps to enhance the stability and overall strength of the freezer structure, reduces the weak links in the structure, and improves the use safety. The guiding structure 111 without a card slot hole 111d plays a connecting and supporting role on the outer wall 11A, ensuring that the inner liner 2 can be firmly fixed in the correct position and effectively preventing the inner liner 2 from shifting or shaking due to vibration or external force.

[0052] Furthermore, referring to Figure 8 , the guiding structure 111 further includes a support rib 111e. The support rib 111e is arranged at the bottom of the limiting slot. The support rib 111e connects the vertical portion 111c and the inner limiting wall 11. Further, a plurality of support ribs 111e are provided between the vertical portion 111c and the inner limiting wall 11, and the plurality of support ribs 111e are arranged at intervals in sequence.

[0053] The guiding structure 111 includes a support rib 111e. The support rib 111e is arranged at the bottom of the limiting slot and connects the vertical portion 111c and the limiting wall 11, which can enhance the stability and support of the structure, effectively bear the weight of the inner liner 2, and prevent the inner liner 2 from sagging or shaking. The support rib 111e connects the vertical portion 111c and the limiting wall 11, supports the inner liner 2 to be firmly fixed in the limiting slot, reduces the movement and shaking of the inner liner 2, and improves the stability and use safety of the freezer. The support rib 111e enhances the durability and stability of the structure, reduces the deformation or damage caused by long-term use, and extends the service life of the freezer. The establishment of the support rib 111e enhances the integrity of the freezer structure and improves the stability of the structure.

[0054] Furthermore, as Figures 6 - 7 shown, both the inner and outer limiting walls 11 are inclined, and the inner and outer limiting walls 11 are gradually approaching each other along the direction from the slot opening of the limiting slot to the slot bottom of the limiting slot.

[0055] The inner and outer limiting walls 11 are inclined and gradually approach each other along the direction of the limiting slot, increasing the stability of the structure, ensuring that the inner liner 2 can be firmly installed in the limiting slot, and improving the overall stability of the freezer. The inclined setting and the gradually approaching design of the limiting wall 11 enable the inner liner 2 to be smoothly inserted and fixed in the correct position, reduce the difficulties that may be encountered during the installation of the inner liner 2, and improve the installation convenience.

[0056] The inner and outer limiting walls 11 gradually approach each other along the direction of the limiting slot, forming a progressive setting, which is beneficial to optimizing the overall performance of the freezer structure and improving the use stability and durability of the freezer.
