Description

Technical Field

[0001] The invention relates to the technical field of refrigerator door sealing structures, in particular to a tensioned and easily assembled door sealing structure. Background Art

[0002] The freezer door seal, as a vital component of the freezer structure, plays a key role in maintaining the low temperature environment inside the freezer, preventing cold air from leaking out, and ensuring the freshness and safety of food. It is usually made of materials with excellent flexibility, low temperature resistance, aging resistance and certain elasticity, such as silicone, rubber or special polymer synthetic materials. The selection of these materials is to ensure that the door seal can maintain stable sealing performance under various extreme temperature conditions. The design of the freezer door seal is often very delicate, with a magnetic strip embedded inside, which allows the door seal to fit tightly on the freezer door frame to form an effective barrier. When the freezer door is closed, the magnetic force generated by the magnetic strip will attract the door seal to fit tightly with the door frame. Even if the door is opened and closed frequently, it can ensure that the door seal will not loosen due to vibration or external force, thereby maintaining a continuous sealing effect. In addition to the physical sealing function, the freezer door seal also has the function of preventing external The door seal of the freezer is a kind of airtight container that can prevent pollutants from entering the freezer. It can effectively block the invasion of dust, insects and other tiny particles, thereby protecting the food stored in the freezer from contamination, which is essential for maintaining the sanitary quality of food and extending its shelf life. In daily use, the maintenance and care of the freezer door seal is also essential. Since the door seal is often in contact with food, hands and the environment, it is easy to accumulate stains, frost and bacteria. Regularly cleaning the surface of the door seal, removing stains and frost, and using disinfectants for sterilization are the keys to maintaining the hygiene of the door seal and extending its service life. In addition, it is also important to regularly check whether the freezer door seal has signs of damage, deformation or aging. Once these problems are found in the door seal, it should be replaced immediately to avoid affecting the sealing performance and refrigeration effect of the freezer. Otherwise, the leakage of cold air will lead to increased energy consumption of the freezer, and will also affect the preservation quality and safety of food.

[0003] Conventional freezer door seals usually have a slot on the door, with a small outer diameter and a large inner diameter. The door seal is in an I-shape and is installed by pressing the protrusion on the back of the door seal into the slot. The protrusion on the back of the door seal is usually shorter overall, making it difficult to align with the slot for pressing during installation. The small outer diameter of the slot requires employees to spend more effort to press, resulting in poor installation efficiency and a low production drop rate. Summary of the invention

The door seal is placed in the groove of the inner shell close to the freezer side, and the edge strip of the front of the door seal is pulled outward on the other side. The edge strip of the front of the door seal is deformed by the tension, and the width is narrowed and passes through the groove, and then the shape is restored, so that the root position of the door seal is clamped into the groove, and then the inner shell with the door seal is installed in the outer shell. The clamping structure at the root position can be easily deformed and entered, so that the root position can be clamped tighter and the gap of the access part is smaller, which is not only easy to assemble but also has better waterproof performance.

[0008] Preferably, a fixing groove is provided at the side door sealing groove, and the fixing groove is arranged at intervals along the side door sealing groove. The fixing groove is in a convex shape, and the end is in a convergent shape, which can provide extrusion force to the door seal.

[0009] Preferably, a protruding cavity is provided in the inner shell, and the protruding cavity protrudes outwards toward a side away from the refrigerator.

[0010] Preferably, a buckle is provided on the inner wall of the C-shaped groove. The buckle is in the shape of an inverted triangle and is arranged above the square notch and on the inner wall of the C-shaped groove near the center of the inner shell.

[0011] Preferably, a capsule is provided below the buckle, the capsule passes through the C-shaped groove, and the internal filler is not filled.

[0012] Preferably, a reinforcing rib is provided on the inner wall of the outer shell, and when the inner shell is installed inside the outer shell, the reinforcing rib just abuts against the outward protrusion of the edge of the inner shell due to the setting of the notch.

[0013] (III) Beneficial effects: Compared with the prior art, the present invention provides a tensioned and easy-to-assemble door seal structure, which has the following beneficial effects: 1. Compared with the traditional I-shaped door seal, when installing the tensioned and easy-to-assemble door seal structure, workers need to press the door seal hard to make it pass through the gradually widening slot. This installation process is not only laborious, but also easy to be unable to accurately judge whether the door seal is completely in place due to obstructed vision. The strip structure door seal in the present invention is combined with the through-hole slot design, allowing workers to easily clip the door seal into the slot by tightening the side strip at the front of the door seal outward. The installation process is more intuitive and simple, which greatly shortens the installation time and improves production efficiency. The opening is designed as a through hole, and the installer can directly observe the installation status of the door seal, including whether it is fully inserted, whether there is any deviation or wrinkles, etc. This visual installation process helps to immediately find and correct errors, ensure the sealing performance of the door seal is in the best state, and reduce the problem of cold leakage caused by improper installation. The design of the strip structure door seal makes it easier to fine-tune it during installation. If the door seal position is slightly deviated or wrinkled during installation, just gently adjust the side strip at the front of the door seal without completely disassembling and reinstalling it. This flexibility improves the installation efficiency and the final installation quality of the door seal. In the traditional installation method, due to the need for strong Pressing the door seal into the notch with excessive force may cause unnecessary stress on the door seal material, affecting its stability and lifespan in long-term use. The installation method of the present invention avoids such excessive physical pressure, reduces the risk of damage to the door seal material, and thus extends the service life of the door seal. The design that is easy to install and inspect means that in the future maintenance and replacement process, it can also be operated more conveniently and quickly, reducing the time and labor costs required for replacing or repairing the door seal. For the end user, a firmly installed and well-sealed freezer door seal can not only effectively maintain the low temperature environment in the freezer and reduce energy consumption, but also prevent external moisture from invading and protect food. The door seal structure of the present invention ensures the best performance of the door seal by optimizing the installation process, thereby improving the user experience and satisfaction. Since the door seal adopts a strip structure design, the door seal can be ensured to fit tightly in the groove of the inner shell by pulling the side strips at the front of the door seal outward. The side strips at the front of the door seal are deformed by the tension, and after narrowing and passing through the groove, they restore their shape. The root structure of the door seal is clamped with the groove to form a tight barrier. This installation method not only makes the installation of the door seal easier, but also ensures a closer contact between the door seal and the groove, thereby effectively preventing moisture and other external contaminants from entering the interior of the freezer.

[0014] 2. The tensioned and easy-to-assemble door seal structure divides the slot into a side door seal slot and a C-shaped slot, so that the door seal can be installed in two parts. This modular design not only simplifies the installation process, but also improves the flexibility of installation. If one part of the door seal is damaged, there is no need to replace the entire door seal, only the damaged part needs to be replaced, thereby reducing maintenance costs. The traditional rectangular door seal is difficult to install as a whole, and it is difficult to adjust once it is offset. The modular installation method of this design allows the installer to handle the side door seal slot and the C-shaped slot separately, making the installation process easier. At the same time, it is easier to adjust the position of the door seal to ensure the accuracy of installation. There are square slots inside the C-shaped slot. These slots are arranged along the C-shaped slot array, allowing the use of different shapes. Door seal, this design enables the door seal to fit more closely to the edge of the freezer door, improving the sealing performance. At the same time, it also provides designers with more creative space and allows them to customize the shape and size of the door seal according to actual needs. An installation groove is provided on the edge of the inner shell, and an installation clip is provided at the corresponding position of the outer shell. This design allows the inner and outer shells to be firmly connected together by simply pressing, without the need for additional fasteners or tools. This not only simplifies the installation process, but also improves the stability and reliability of the structure. Since the inner and outer shells can be connected by pressing, the inner shell can be more easily removed and reinstalled when replacing or repairing the door seal. This design improves maintenance efficiency and reduces the time the freezer is interrupted due to replacement of the door seal.

[0015] 3. The tensioned easy-to-assemble door seal structure is provided with fixing grooves at the side door seal grooves, and these fixing grooves are arranged at intervals along the side door seal grooves, in a convex shape and with converged ends. Such a design can provide effective extrusion force to the door seal. When the door seal is installed, when the door seal is tightened outward and stuck in the fixing groove, due to the shape characteristics of the fixing groove, the door seal will be squeezed from the fixing groove, thereby ensuring that the door seal is not easy to fall off during daily use, which greatly improves the stability of the door seal and extends the service life of the door seal. At the same time, it also reduces the problems such as cold air leakage caused by the falling off of the door seal. A convex cavity is provided in the inner shell. This design effectively extends the internal space of the freezer. The convex cavity convexes outward to the side away from the freezer, which not only increases the storage capacity of the freezer, but also makes the internal layout of the freezer more reasonable and improves the space utilization rate. The over-fine design, such as the convex and converged ends of the fixing groove, and the reasonable layout of the convex cavity, these structural features jointly improve the reliability and durability of the overall structure of the freezer. Such a design not only improves the product performance, but also enhances the user's satisfaction and trust.

[0016] 4. The tensioned and easy-to-assemble door seal structure can effectively fix the door seal in the C-shaped groove by designing an inverted triangular buckle on the inner wall of the C-shaped groove and sliding it downward along the edge of the buckle when installing the door seal. After installation, the buckle plays a limiting role to prevent the door seal from accidentally falling out of the C-shaped groove, thereby ensuring the stability and durability of the door seal. The design of the bladder body allows the bladder body located on the outer part of the C-shaped groove to expand the bladder body located on the inner part of the C-shaped groove when the door seal needs to be removed. This expansion effect can push the door seal to deviate in the direction away from the buckle. This releases the limit of the door seal by the buckle, allowing the door seal to be easily removed. This design greatly simplifies the disassembly process of the door seal and improves the convenience of operation. The reinforcing ribs arranged on the inner wall of the outer shell can resist the outward protrusion of the edge of the inner shell due to the setting of the groove when the inner shell is installed on the inner side of the outer shell. This design not only enhances the stability of the entire structure, but also improves the durability and impact resistance of the product. The presence of the reinforcing ribs also helps to disperse and reduce the impact of external pressure on the connection between the inner shell and the outer shell, thereby extending the service life of the product.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 4 , a tensioned and easy-to-assemble door seal structure, comprising an outer shell 1 and an inner shell 2, one side of the outer shell 1 is provided with a rotating shaft 11, the inner shell 2 is installed on the inner side of the outer shell 1 to form a refrigerator door, and is installed on the refrigerator through the rotating shaft 11, the inner shell 2 is provided with a notch for door seal installation, and the notch is a through hole and is arranged along the edge of the inner shell 2, a cavity is left between the inner shell 2 and the outer shell 1, and the door seal is a strip structure (see Fig. 9 , the left side of the figure is the front part of the door seal), the end is designed as an edge strip structure that is easy to insert, and the length of the edge strip is greater than 10mm, and a protrusion for clamping is provided at the root of the door seal. The door seal is placed in the notch on the side of the inner shell 2 close to the refrigerator, and the edge strip of the front part of the door seal is pulled outward on the other side. The edge strip of the front part of the door seal is deformed by the tension, and the width is narrowed. After passing through the notch, it restores its shape, so that the root of the door seal is clamped into the notch (see Fig. 9 , the left side is the door seal in the process of tightening, and the right side is the door seal that has been installed), and then the inner shell 2 with the door seal is installed in the outer shell 1, which can make the card-in structure at the root position easy to deform and enter, so that the root position can be carded tighter and the gap of the access part is smaller, which is not only easy to assemble but also has better waterproof performance.

[0029] The door seals currently on the market use an I-shaped structure, and a notch corresponding to the shape of the door seal is provided on the inner side of the refrigerator door. During installation, workers need to press the door seal into the notch, and the shape of the notch is generally small on the outer side and large on the inner side, to ensure that the door seal can be stuck after being pressed in, but this makes installation extremely difficult, and after installation, it is impossible to observe whether the interior is completely inserted. The present invention divides the cabinet door into two parts, an outer shell 1 and an inner shell 2, changes the notch for installing the door seal into a through hole on the inner shell 2, and designs the door seal into a strip structure. By pulling the front of the door seal outward, the door seal can be inserted into the notch. The door seal is designed with a strip structure, and by tightening the side strip at the front of the door seal outward, it can be ensured that the door seal fits tightly in the notch of the inner shell 2 to form a tight barrier. This installation method not only makes the installation of the door seal easier, but also ensures that the contact between the door seal and the notch is closer, thereby effectively preventing moisture and other external contaminants from entering the interior of the freezer.

[0030] The notch is composed of a side door seal notch 21 and a C-shaped notch 22. The side door seal notch 21 is arranged on the side away from the rotating shaft 11. The C-shaped notch 22 is a C-shaped groove, which is arranged at the edge of the inner shell 2 where the side door seal notch 21 is not provided. A square notch 221 is provided inside the C-shaped notch 22 for the door seal protrusion to pass through. The door seals of freezers on the market are all in a whole rectangle, which is difficult to install as a whole and difficult to adjust after offset. The door seal notch is divided into the side door seal notch 21 and the C-shaped notch 22, so that the door seal can also be divided into two parts for installation, which makes installation easier. At the same time, it does not need to be replaced as a whole during subsequent replacement, and different door seal shapes can be adopted according to different positions. The square notch 221 is arrayed along the C-shaped notch 22.

[0031] The inner shell 2 has an edge with a mounting groove 24 , and the outer shell 1 has a mounting fixture 13 at a position corresponding to the mounting groove 24 of the inner shell 2 , so that the inner shell 2 can be installed into the outer shell 1 by pressing, making installation easier.

[0032] See also Figure 5-Figure 6The side door seal groove 21 is provided with a fixing groove 211, and the fixing groove 211 is arranged at intervals along the side door seal groove 21. The fixing groove 211 is in a convex shape and the end is in a convergent shape, which can provide an extrusion force to the door seal, so that when the door seal is installed and tightened outward, the door seal is clamped into the fixing groove 211 to generate an extrusion force, thereby preventing the door seal from falling off during daily use. This greatly improves the stability of the door seal and extends the service life of the door seal. At the same time, it also reduces the problems such as cold air leakage caused by the falling off of the door seal. A convex cavity 23 is provided in the inner shell 2, and the convex cavity 23 convexes outwardly toward the side away from the freezer, thereby extending the internal space of the freezer. The inner shell 2 is provided with a convex cavity 23, and this design effectively extends the internal space of the freezer. The convex cavity 23 convexes outwardly toward the side away from the freezer, thereby not only increasing the storage capacity of the freezer, but also making the internal layout of the freezer more reasonable, thereby improving the space utilization rate.

[0033] See also Figure 7-Figure 8 A buckle 222 is provided on the inner wall of the C-shaped groove 22. The buckle 222 is in an inverted triangle shape and is arranged above the square notch 221 and on the inner wall of the C-shaped groove 22 near the center of the inner shell 2. By designing the shape of the door seal, the door seal can be moved downward along the edge of the buckle 22 when installed into the C-shaped groove 22. When the installation is completed, the buckle 222 is used to limit the door seal and the door seal does not fall out of the C-shaped groove 22. A capsule 223 is provided below the buckle 222. The capsule 223 passes through the C-shaped groove 22 and the internal filler is not filled. When the door seal needs to be removed, the capsule located on the outer part of the C-shaped groove 22 is squeezed to expand the capsule located on the inner part of the C-shaped groove 22, so that the door seal is offset to the side away from the buckle 222, so that the door seal is not limited by the buckle 222 and can be easily removed.

[0034] See also Figure 4 The outer shell 1 is provided with reinforcing ribs on its inner wall. When the inner shell 2 is installed inside the outer shell 1, the reinforcing ribs just abut against the outward protrusion of the edge of the inner shell 2 due to the setting of the notch. This design not only enhances the stability of the entire structure, but also improves the durability and impact resistance of the product. The presence of the reinforcing ribs also helps to disperse and reduce the impact of external pressure on the connection between the inner shell and the outer shell, thereby extending the service life of the product.

[0035] Working principle: The inner shell 2 is installed inside the outer shell 1 to form a freezer door, which is installed on the freezer through the rotating shaft 11. The inner shell 2 is provided with a notch for installing the door seal, and the notch is a through hole and is arranged along the edge of the inner shell 2. A cavity is left between the inner shell 2 and the outer shell 1. The door seal is a strip structure (see Fig. 9, the left side of the figure is the front part of the door seal), place the door seal in the notch of the inner shell 2 close to the side of the freezer, tighten the edge strip of the front part of the door seal outward on the other side, so that the door seal is stuck in the notch, and then install the inner shell 2 with the door seal in the outer shell 1. The door seal on the market now adopts an I-shaped structure, and a notch corresponding to the shape of the door seal is provided on the inner side of the freezer door. During installation, the worker needs to press the door seal into the notch. The shape of the notch is generally small on the outside and large on the inside to ensure that the door seal can be stuck after being pressed in. However, it will make the installation extremely difficult, and after installation, it is impossible to observe whether the interior is completely stuffed. The present invention divides the cabinet door into two parts, an outer shell 1 and an inner shell 2, and changes the notch for installing the door seal into a through hole on the inner shell 2. The door seal is designed to be a strip structure, and the door seal is installed in the notch of the inner shell 2 by pulling the side strip at the front of the door seal outward. The whole structure is easier, and the installation status can be observed intuitively to see whether offset and wrinkles have occurred. At the same time, the door seal can be adjusted by pulling the side strip at the front of the door seal.
