Description

Technical Field

[0001] This utility model belongs to the field of evaporator pipeline fixing technology, and in particular relates to a fixing tool for refrigerator evaporators. Background Technology

[0002] Ultra-low temperature freezers are special freezing devices, typically operating at -80°C or lower, used to store high-value substances such as biological samples, bacterial strains, and pharmaceuticals. The storage of these substances often requires maintaining a specific temperature within the freezer, while also ensuring temperature uniformity.

[0003] The evaporator is a crucial component of the refrigerator's refrigeration system. Its function is to absorb heat from the refrigerator's interior, lowering the internal temperature to achieve the purpose of refrigerating and freezing food. The evaporator's piping typically attaches to the outer wall of the inner liner in a winding, meandering pattern to cool the interior. In existing technologies, some evaporators are installed by first laying the evaporator piping along the inner liner's side wall and then finally fixing it in place. Because the evaporator piping is winding along the height of the inner liner, it is prone to misalignment under gravity and / or its own elasticity. This not only increases the difficulty of laying the evaporator piping but also makes it easy for the piping to deviate from its original position, resulting in uneven cooling of the inner liner.

[0004] Therefore, designing a fixing fixture that can constrain and limit the piping of the evaporator is of great significance for the installation and fixing of the evaporator piping on the inner tank. Utility Model Content

[0005] In view of the shortcomings of the related technologies, this utility model provides a fixing fixture for refrigerator evaporators. By limiting and temporarily fixing the evaporator pipes during the laying process, the evaporator pipes can be arranged and fixed on the outer wall of the inner liner.

[0006] This utility model provides a fixing fixture for a refrigerator evaporator, located outside the refrigerator liner, used to limit the position of the evaporator pipes on the outer wall of the liner; the fixing fixture includes:

[0007] The fixing strip has a through-hole for the evaporator pipes to pass through; the through-hole has an inlet and outlet for the evaporator pipes to enter and exit the through-hole, and the inlet and outlet are located on the side of the fixing strip facing the inner tank;

[0008] A connector that is attached to a fixing strip and is detachably attached to the inner liner.

[0009] This technical solution incorporates a through-hole in the fixing strip, allowing the evaporator piping to pass through. This constraint and limitation of the evaporator piping by the fixing strip facilitates its arrangement and temporary fixation. Furthermore, by providing inlets and outlets on the side of the fixing strip facing the inner liner, the evaporator piping located on the outer wall of the inner liner can be positioned within the through-hole. This not only facilitates the constraint and temporary fixation of the evaporator piping by the fixing strip but also allows direct contact between the evaporator piping and the side wall of the inner liner, increasing the evaporator's cooling effect on the inner liner. Finally, by providing a connector that connects to the inner liner, the fixing strip is secured, further enhancing its constraint and limitation effect on the piping.

[0010] In some embodiments, the top and bottom of the fixing strip are respectively provided with connectors, the connector at the top of the fixing strip is detachably connected to the top of the inner liner, and the connector at the bottom of the fixing strip is detachably connected to the bottom of the inner liner.

[0011] This technical solution increases the strength of the connection between the fixing strip and the inner liner by setting connectors at the top and bottom of the fixing strip, so that the connector at the top of the fixing strip can be detachably connected to the top of the inner liner, and the connector at the bottom of the fixing strip can be detachably connected to the bottom of the inner liner. This increases the constraint effect of the fixing strip on the evaporator pipeline.

[0012] In some embodiments, the connector is provided with a first mounting hole, and the inner liner is provided with a second mounting hole. The second mounting hole is provided in a corresponding manner to the first mounting hole, and the same fastener is provided in both the second mounting hole and the first mounting hole, so that the connector is connected to the inner liner.

[0013] This technical solution achieves the connection between the connector and the inner liner by setting a first mounting hole in the connector and a second mounting hole in the inner liner, so that the second mounting hole corresponds to the first mounting hole, and the same fastener is simultaneously installed in the first mounting hole and the second mounting hole.

[0014] In some embodiments, the fixing strip includes a first connecting plate, a second connecting plate, and a third connecting plate; the first connecting plate, the second connecting plate, and the third connecting plate are connected to each other to form a U-shaped structure; the first connecting plate is in contact with the outer wall of the inner liner, and the inlet and outlet are opened on the first connecting plate; the second connecting plate is connected to the side of the first connecting plate away from the inner liner, and the through portion is provided on the second connecting plate; the third connecting plate is connected to the side of the second connecting plate away from the first connecting plate, and the connector is connected to the third connecting plate.

[0015] In some embodiments, the first connecting plate, the second connecting plate, and the third connecting plate extend along the height direction of the inner liner; the end of the connector away from the third connecting plate extends toward the first connecting plate, and the length of the connector is greater than the horizontal distance between the third connecting plate and the first connecting plate.

[0016] In some embodiments, the inlet and outlet decrease sequentially along the evaporator piping toward the second connecting plate.

[0017] This technical solution reduces the size of the inlet and outlet along the evaporator pipe towards the second connecting plate, so that the evaporator pipe can pass through the through section.

[0018] In some embodiments, the evaporator piping includes a straight section that extends circumferentially along the inner liner; the straight section passes through a through-hole.

[0019] In some embodiments, multiple straight segments are provided, arranged along the height direction of the inner liner, and multiple through-parts are provided, with each through-part corresponding to one of the multiple straight segments.

[0020] In some embodiments, multiple fixtures are provided, and the multiple fixtures are arranged circumferentially along the inner liner.

[0021] This technical solution increases the constraint effect of the fixtures on the evaporator piping by setting multiple fixtures and arranging them around the circumference of the inner liner.

[0022] In some embodiments, the fixing strips are provided with marking holes, and the number of marking holes on different fixing strips is different, so as to sort the setting positions of multiple fixing fixtures by the number of marking holes.

[0023] This technical solution sets marking holes on the fixing strips, and makes the number of marking holes different on different fixing strips, so as to sort multiple fixing fixtures according to the number of marking holes, thereby quickly locating the setting position of the fixing fixtures in the inner liner.

[0024] Based on the above technical solution, the fixing fixture for the refrigerator evaporator in this embodiment of the utility model limits and constrains the evaporator pipeline, so that the evaporator pipeline is accurately positioned and arranged on the inner liner side wall, ensuring the uniformity of the evaporator's cooling effect on the inner liner. Moreover, it can allow the evaporator pipeline to directly contact the inner liner side wall, increasing the evaporator's cooling effect on the inner liner. Furthermore, the fixing fixture has a simple overall structure, is easy to assemble and disassemble, and can be reused, reducing the installation cost of the evaporator. Attached Figure Description

Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The refrigerator includes a cabinet and a door. The cabinet includes an outer shell and an inner liner 1. The inner liner 1 is located inside the outer shell and forms a refrigerator compartment inside the inner liner 1. The refrigerator compartment is used to hold items to be refrigerated. An evaporator is connected to the outer wall of the inner liner 1. The evaporator is used to cool the refrigerator compartment of the inner liner 1. The refrigerator compartment has an opening facing the front of the refrigerator, and the door is used to close the refrigerator compartment opening.

[0041] In some ultra-low temperature refrigerators, in order to increase the cooling effect of the evaporator on the inner liner 1, the evaporator pipe 2 is usually set close to the inner liner 1 to increase the heat exchange between the evaporator and the inner liner 1, and / or the evaporator pipe 2 is set to meander on the outer wall of the inner liner 1 to increase the heat exchange area between the evaporator and the inner liner 1, thereby increasing the heat exchange between the evaporator and the inner liner 1.

[0042] Because the evaporator pipe 2 is set up in a meandering manner along the height direction of the inner tank 1, it is easy for the evaporator pipe 2 to be misaligned and moved under the action of gravity and / or the elasticity of the pipe itself. This not only increases the difficulty of laying out the evaporator pipe 2, but also makes it easy for the evaporator pipe 2 to deviate from its original set position, resulting in uneven cooling effect of the evaporator on the inner tank 1.

[0043] Based on this, the present invention provides a fixing fixture for a refrigerator evaporator. By limiting and temporarily fixing the evaporator pipe 2 during the laying process, the evaporator pipe 2 is accurately positioned and arranged on the inner liner 1, and the evaporator pipe 2 is conveniently arranged and fixed on the outer wall of the inner liner 1.

[0044] As attached Figures 1-5 As shown in an illustrative embodiment of the fixing fixture for a refrigerator evaporator according to the present invention, the fixing fixture for the refrigerator evaporator is located outside the refrigerator inner liner 1 and is used to limit the setting position of the evaporator pipe 2 on the outer wall of the inner liner 1. The fixing fixture 3 includes a fixing strip 32 and a connector 31. The fixing strip 32 is used to limit and constrain the evaporator pipe 2. The fixing strip 32 is provided with a through part 321 for the evaporator pipe 2 to pass through. The through part 321 is provided with an inlet and outlet for the evaporator pipe 2 to enter and exit the through part 321. The inlet and outlet are located on the side of the fixing strip 32 facing the inner liner 1. The connector 31 is connected to the fixing strip 32 and is detachably connected to the inner liner 1 so that the fixing strip 32 is connected to the inner liner 1.

[0045] The aforementioned fixture for fixing the refrigerator evaporator has a through-hole 321 on the fixing strip 32 and an inlet / outlet on the side of the fixing strip 32 facing the inner liner 1. This allows the evaporator pipe 2 to be installed in the through-hole 321 through the inlet / outlet, thus constraining and limiting the evaporator pipe 2. This facilitates the arrangement and temporary fixing of the evaporator pipe 2. It not only makes it convenient for the fixing strip 32 to limit and temporarily fix the evaporator pipe 2, but also allows the evaporator pipe 2 to directly contact the side wall of the inner liner 1, increasing the cooling effect of the evaporator on the inner liner 1. By providing a connector 31, the connector 31 is connected to the inner liner 1 to fix the fixing strip 32, thereby increasing the limiting and constraining effect of the fixing strip 32 on the pipe.

[0046] like Figure 1 As shown, the evaporator pipe 2 includes straight sections, which are arranged circumferentially along the inner liner 1 and pass through through-holes 321. Multiple straight sections are arranged along the height of the inner liner 1, and multiple through-holes 321 are provided, each corresponding to one of the multiple straight sections, so that the same fixing bar 32 can simultaneously limit and constrain multiple straight sections.

[0047] In some embodiments, the straight line segment is arranged in a horizontal direction.

[0048] The evaporator piping 2 also includes a bend section, which connects to the straight section to change the orientation of the evaporator piping 2. When there are multiple straight sections, there are also multiple bend sections. The multiple straight sections and multiple bend sections are spaced apart to ensure that the evaporator piping 2 is installed both circumferentially and vertically along the inner liner 1. It should be noted that one bend section connects to two adjacent straight sections; that is, two adjacent straight sections are connected to each other by a bend section.

[0049] In the above-mentioned fixture for fixing the refrigerator evaporator, when the evaporator pipe 2 is located on the outer wall of the inner liner 1, the evaporator pipe 2 is located in the through part 321 from the inlet and outlet, so that the fixing strip 32 can constrain and limit the evaporator pipe 2, thereby arranging and temporarily fixing the evaporator pipe 2.

[0050] like Figure 2 , Figure 3 and Figure 5As shown, the fixing strip 32 includes a first connecting plate 322, a second connecting plate 324, and a third connecting plate 323; the first connecting plate 322, the second connecting plate 324, and the third connecting plate 323 are connected to each other to form a U-shaped structure; the first connecting plate 322 is in contact with the outer wall of the inner liner 1, and the inlet and outlet are opened on the first connecting plate 322; the second connecting plate 324 is connected to the side of the first connecting plate 322 away from the inner liner 1, and the through part 321 is provided on the second connecting plate 324; the third connecting plate 323 is connected to the side of the second connecting plate 324 away from the first connecting plate 322, and the connector 31 is connected to the third connecting plate 323.

[0051] In some embodiments, the through portion 321 is a fixing groove provided on the second connecting plate 324. The fixing groove is a through groove provided along the extension direction of the straight segment, and the side of the fixing groove near the first connecting plate 322 is open. The opening of the fixing groove is connected to the inlet and outlet, so that the evaporator pipe 2 can be provided in the fixing groove from the inlet and outlet, and the evaporator pipe 2 can pass through the fixing groove when it is provided in the fixing groove.

[0052] In some embodiments, the first connecting plate 322, the second connecting plate 324, and the third connecting plate 323 are formed by bending the same metal sheet, which simplifies the manufacturing process of the fixing strip 32, improves the manufacturing efficiency of the fixing strip 32, reduces the manufacturing cost of the fixing strip 32, and can also increase the overall strength of the fixing strip 32.

[0053] In some embodiments, the first connecting plate 322, the second connecting plate 324 and the third connecting plate 323 extend along the height direction of the inner liner 1; the end of the connector 31 away from the third connecting plate 323 extends toward the first connecting plate 322, and the length of the connector 31 is greater than the horizontal distance between the third connecting plate 323 and the first connecting plate 322.

[0054] When the evaporator pipe 2 is located inside the through section 321, the first connecting plate 322 is in contact with the outer wall of the inner liner 1. Since the third connecting plate 323 is located on the side of the first connecting plate 322 away from the inner liner 1, the connecting piece 31 can only be connected to the inner liner 1 when the length of the connecting piece 31 is greater than the horizontal distance between the third connecting plate 323 and the first connecting plate 322.

[0055] In some embodiments, the inlet and outlet decrease sequentially in the direction of the straight segment toward the second connecting plate 324 so that the evaporator pipe 2 can pass through the through portion 321.

[0056] like Figure 3As shown, the connector 31 has a first mounting hole 312, and the inner liner 1 has a second mounting hole. The second mounting hole corresponds to the first mounting hole 312, and the same fastener is provided in both the second mounting hole and the first mounting hole 312 to connect the connector 31 to the inner liner 1. It should be noted that the fastener is a bolt or screw, etc.

[0057] like Figure 1 and Figure 4 As shown, the top and bottom of the third connecting plate 323 are respectively provided with connectors 31. The connector 31 located at the top of the third connecting plate 323 is detachably connected to the top of the inner liner 1, and the connector 31 located at the bottom of the third connecting plate 323 is detachably connected to the bottom of the inner liner 1, so as to increase the firmness of the connection between the fixing strip 32 and the inner liner 1, thereby increasing the constraint effect of the fixing strip 32 on the evaporator pipe 2.

[0058] In some embodiments, the first connecting plate 322, the second connecting plate 324, and the third connecting plate 323, as well as the connectors 31 located at the top and bottom of the third connecting plate 323, are formed by bending the same metal plate to simplify the manufacturing process, improve manufacturing efficiency, and increase overall strength.

[0059] like Figure 1 As shown, multiple fixtures 3 are provided, and the multiple fixtures 3 are arranged along the circumference of the inner liner 1 to increase the constraint effect of the fixtures 3 on the evaporator pipeline 2.

[0060] In practical applications, the evaporator pipe 2 is usually a single pipe. The meandering arrangement of the evaporator pipe 2 on the outer wall of the inner liner 1 can also be considered as the routing of the evaporator pipe 2 on the outer wall of the inner liner 1. The spacing between multiple straight segments and the direction of extension of the straight segments on the outer wall of the inner liner 1 will also vary. For example, there may be an angle between two adjacent straight segments, and the distance between two through parts 321 on the same fixture 3 will vary depending on the placement of the fixture 3.

[0061] Based on this, such as Figure 2 , Figure 3 and Figure 5 As shown, the fixing strip 32 is provided with marking holes 311. The number of marking holes 311 on different fixing strips 32 is different, so as to sort the setting positions of multiple fixing fixtures 3 by the number of marking holes 311, thereby quickly locating the setting position of the fixing fixture 3 in the inner liner 1.

[0062] The above-mentioned fixing fixtures for refrigerator evaporators are used in the following steps and working principle: First, the evaporator pipes 2 are laid on the outer wall of the inner liner 1 roughly according to the preset routing trajectory. At this time, the evaporator pipes 2 lack constraints and may shift or become misaligned, but the approximate routing trajectory of the evaporator pipes 2 is the same as the preset routing trajectory. The connector 31 at the top of the fixing strip 32 is aligned with the top of the inner liner 1, and the connector 31 at the bottom of the fixing strip 32 is aligned with the bottom of the inner liner 1, so that multiple fixing fixtures 3 are placed in the designated positions according to the marked holes 311. During the tooling process, since the tooling 3 and the inner liner 1 have not yet been fixedly connected, and the inner liner 1 has not completely sealed the inlet and outlet, the straight section of the side where the tooling 3 is placed is set in the corresponding through part 321 so that the tooling 3 can limit and constrain the evaporator pipe 2; then the tooling 3 and the inner liner 1 are fixedly connected by screws; at this time, the evaporator pipe 2 is temporarily fixed to the outer wall of the inner liner 1 under the action of the tooling 3. After the evaporator pipe 2 is fixedly connected to the inner liner 1 by existing pipe fixing methods such as connecting pieces or welding, the screws are removed and the tooling 3 is taken off.

[0063] It should be noted that, due to the flexibility of the evaporator piping 2, when the fixing fixture 3 constrains the evaporator piping 2, the constraint effect of the fixing fixture 3 is better on the portion of the evaporator piping 2 closest to it, and the constraint effect is worse on the portion farther away from the fixing fixture 3. When multiple fixing fixtures 3 are set, the fixing fixtures 3 are installed one by one, so that the fixing fixtures 3 constrain the corresponding portions of the evaporator piping 2.

[0064] One existing method for installing an evaporator involves setting a groove on an installation strip to fix the evaporator pipe 2. The installation strip is first connected to the inner tank 1 by welding or anchoring, and then the evaporator pipe 2 is placed in the groove. Although this method can constrain the evaporator pipe 2, the gap between the evaporator and the inner tank 1, which is the thickness of the installation strip, can easily cause poor sealing. After foaming, foaming agent will fill the gap, affecting the cooling effect. On the other hand, foaming the installation strip into the inner tank not only increases the cost of the product but also increases its weight, which is not in line with the concept of sustainable development from an environmental perspective.

[0065] Compared to existing evaporator installation methods, the aforementioned fixing fixture 3 for refrigerator evaporators not only effectively solves the problem of fixing the evaporator pipe 2 to the inner liner 1, allowing the evaporator pipe 2 and the inner liner 1 wall to be in direct contact without gaps, but also allows for recycling, reducing product costs and weight, and aligns with the concept of sustainable development from an environmental perspective; furthermore, the fixing fixture 33 has a simple, stable, and reliable structure and is easy to install.

[0066] The aforementioned fixture for fixing the refrigerator evaporator limits and constrains the evaporator pipe 2, ensuring that the evaporator pipe 2 is precisely positioned and accurately arranged on the side wall of the inner liner 1, thus guaranteeing the uniformity of the evaporator's cooling effect on the inner liner 1. Furthermore, the evaporator pipe 2 can directly contact the side wall of the inner liner 1, increasing the evaporator's cooling effect on the inner liner 1. In addition, the fixture 3 has a simple overall structure, is easy to assemble and disassemble, and can be reused, reducing the installation cost of the evaporator.

[0067] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0068] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
