Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to a box liner component and refrigeration equipment. Background Art

[0002] Refrigerators and freezers are widely used in people's daily work and life. They are refrigeration equipment used to refrigerate / freeze food, medicine or other items that require a low-temperature storage environment.

[0003] In the prior art, refrigerators have an inner container and an insulation layer surrounding the inner container. The inner container is used to store various refrigerated items. A refrigeration mechanism can be installed within the insulation layer to cool the inner container, thereby maintaining a constant low-temperature environment inside the container. However, the inner container of traditional refrigerators has poor cold conductivity, resulting in uneven temperatures throughout the container, which affects the refrigerator's cooling or freezing performance. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a box liner component with good cold conductivity, which can make the temperature inside the box liner component uniform and improve the refrigeration or freezing effect.

[0005] The present invention also provides a refrigeration device having the box liner component.

[0006] The box liner component according to the first embodiment of the present invention is applied to a refrigeration device, and the box liner component includes:

[0007] An inner liner assembly, comprising a back plate and a liner body connected to the back plate, the liner body comprising a top wall, a first side wall, a bottom wall, and a second side wall connected in sequence, the top wall, the first side wall, the bottom wall, the second side wall, and the back plate enclosing a storage cavity and an opening communicating with the storage cavity; and

The liner body covers the four sides of the storage cavity, so that the storage cavity can obtain the cold brought by the liner body on all sides, further ensuring the uniform temperature inside the storage cavity, reducing the temperature difference in the storage cavity, and improving the refrigeration / freezing effect. Moreover, compared with plastic material, metal material has higher hardness, is not easy to wear, and is not easy to be scratched to cause stains to be trapped and adsorbed on the surface of the liner body.

[0065] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0068] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0069] The present application provides a box liner component and a refrigeration device, wherein the box liner component is applied to the refrigeration device.

[0070] Specifically, the refrigeration equipment provided in this application can be a freezer, a wine cabinet, a refrigerator, etc. The refrigeration equipment will be described in detail below using a wine cabinet as an example.

[0071] Please refer to Figure 1 , Figure 1 1 is a schematic structural diagram of a refrigeration device according to an embodiment of the present invention. The refrigeration device 10 includes a housing 100 and a door 200 rotatably mounted on the housing 100. The housing 100 may include an outer shell, a refrigeration system, and a housing member.

[0072] The outer shell forms the outer contour of the housing 100 and also positions, supports, seals, and protects the electrical control components / devices, functional components, etc. of the refrigeration device 10. For example, the refrigeration system and liner components of the housing 100 can be positioned and installed within the outer shell.

[0073] The refrigeration system may include a compressor, a condenser, a capillary tube and an evaporator. Among them, the compressor is the heart of the refrigeration system of the refrigeration equipment 10, and the compressor is used to provide power to drive the flow of refrigerant in the refrigeration system. The condenser is the main heat exchange component of the refrigeration system. The condenser is used to exchange heat with the refrigerant flowing through, so that the high-temperature and high-pressure gaseous refrigerant is cooled and liquefied into a medium-temperature and high-pressure liquid refrigerant, and the heat is dissipated to the external environment. The capillary tube is a throttling unit connected between the evaporator and the condenser. The capillary tube achieves throttling through a sudden change in its own cross-section, which can change the pressure of the refrigerant. The evaporator is the main refrigeration component of the refrigeration system. When the medium-temperature refrigerant liquid flowing out of the condenser passes through the evaporator, it evaporates and absorbs heat in the evaporator and becomes a low-temperature and low-pressure gaseous refrigerant, which can reduce the surface temperature of the evaporator and achieve refrigeration.

[0074] Specifically, during the refrigeration process, the refrigerant passes through the compressor and becomes a high-temperature and high-pressure gaseous refrigerant, then flows through the condenser for heat exchange and condenses into a medium-temperature and high-pressure liquid refrigerant, and then passes through the capillary throttling to form a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant evaporates and absorbs heat through the evaporator to become a low-temperature and low-pressure gaseous refrigerant, and finally enters the compressor for compression to complete the refrigeration cycle of the refrigeration equipment 10.

[0075] The box liner component serves as the main load-bearing component and cold-conducting component of the refrigeration device 10, and cooperates with the refrigeration of the refrigeration system to provide a low-temperature storage space for storing items to be refrigerated / frozen.

[0076] Conventional wine coolers typically use plastic linings, such as blister packing. These blister packings have poor heat conductivity, resulting in uneven absorption of cold air across the blister packing, leading to uneven temperatures within the freezer, impacting the wine cooler's refrigeration performance. Furthermore, due to the material properties of plastic, the surface of the blister packings easily develops fine grooves that harbor dirt and grime. Furthermore, plastic's high affinity for grease and oil means that stains left by refrigerated items can easily remain on the blister packings, making them difficult to clean.

[0077] The box liner component provided in the embodiment of the present application can solve the above problems. Figure 2 and Figure 3 , Figure 2 This is a structural diagram of a box liner component according to an embodiment of the present invention. Figure 3 FIG3 is an exploded view of a box liner component according to an embodiment of the present invention. In the embodiment of the present application, the box liner component 300 includes an inner liner assembly and a surrounding frame 330 .

[0078] The inner liner assembly includes a back panel 320 and a liner body 310 connected to the back panel 320. The liner body 310 includes a top wall 310a, a first side wall 310c, a bottom wall 310b, and a second side wall 310d connected in sequence. The top wall 310a, the first side wall 310c, the bottom wall 310b, and the second side wall 310d, together with the back panel 320, form a storage cavity 300a and an opening 300b communicating with the storage cavity 300a. A frame 330 surrounds the opening 300b and is connected to the liner body 310. The liner body 310 is made of metal, while the back panel 320 and the frame 330 are made of plastic. At least one of the back panel 320 and the frame 330 is provided with a support structure.

[0079] It can be understood that the inner liner assembly is composed of a liner body 310 and a back panel 320. The refrigeration equipment 10 includes an insulation layer, which can be formed between the inner liner assembly and the outer shell using a foaming process. The surrounding frame 330 is used to connect the inner liner assembly and the outer shell to seal the insulation layer in the outer shell.

[0080] The bladder body 310 is made of metal. Due to its superior cold conductivity, it conducts cold more effectively and evenly, and cools the food faster than the plastic bladder of conventional refrigeration equipment 10. Furthermore, the upper, lower, left, and right walls of the bladder body 310 are all made of metal, meaning that the entire bladder body 310 is made of metal. The bladder body 310 covers all four sides of the storage cavity 300a, allowing the cooling provided by the bladder body 310 to be shared by all four sides of the storage cavity 300a (or, in other words, the storage cavity 300a can exchange heat with the bladder body 310 for cooling). This further ensures a uniform temperature within the storage cavity 300a, reduces temperature differences within the storage cavity 300a, and improves the refrigeration / freezing effect.

[0081] The refrigeration components of the refrigeration equipment 10, such as the evaporator tube, can cover the top wall 310a, the first side wall 310c, the top wall 310a and the second side wall 310d of the gallbladder body 310. That is, the evaporator tube can be coiled around the outer peripheral wall of the gallbladder body 310. During the refrigeration process of the refrigeration equipment 10, the evaporator tube and the four walls of the gallbladder body 310 fully exchange heat, so that the temperature of the four walls of the gallbladder body 310 is reduced, which can ensure that the temperature of the gallbladder body 310 is uniform throughout.

[0082] In addition, compared with plastic material, metal material is harder and less likely to wear and tear, and is not prone to scratches that cause stains to be absorbed on the surface of the gallbladder body 310. Metal itself is not easy to absorb stains, and the surface of metal material is smoother and has less friction, which makes it easier for users to clean the gallbladder body 310.

[0083] As will be appreciated, the back panel 320 and the surrounding frame 330 are made of plastic. Support structures can be formed on the back panel 320 and the surrounding frame 330 to support components that need to be placed inside the bladder body 310, such as the storage shelf 400. These support structures can be integrally formed during the manufacture of the back panel 320 and the surrounding frame 330, eliminating the need for connection and assembly, thereby simplifying the assembly structure of the bladder member 300. Furthermore, by forming a support structure with the back panel 320 and the surrounding frame 330, there is no need to provide additional support structures on the inner surface of the bladder body 310. This can reduce the thickness of the foam layer and increase the volume of the storage cavity 300a. At the same time, the inner surface of the bladder body 310 can be designed to be flat and smooth, further facilitating cleaning of the bladder body 310 by the user.

[0084] On the other hand, since the frame 330 is also used to connect to the outer shell of the refrigeration equipment 10, the frame 330 is made of plastic, which has very low thermal conductivity and good thermal insulation. The frame 330 can isolate the inner liner assembly and the insulation layer from the external environment, prevent cold air leakage and prevent external heat from entering the inner liner assembly and the insulation layer, thereby improving the insulation effect.

[0085] Understandably, Figure 2 As shown, the refrigeration device 10 may further include a storage shelf 400. A plurality of storage shelves 400 are stacked and installed in the storage cavity 300a, and the storage cavity 300a can be divided into a plurality of small storage spaces for storing items in a classified manner. The storage shelves 400 may be made of glass, plastic, wood, metal, etc.

[0086] The back panel 320 and the surrounding frame 330 may be provided with a support structure for supporting the storage shelf 400 .

[0087] Please refer to Figure 2In one embodiment, the frame 330 includes a plurality of first supports 333 for supporting the storage shelves 400. The plurality of first supports 333 are arranged at intervals along the height of the liner member 300. The back panel 320 includes a plurality of second supports 323 for supporting the storage shelves 400. The plurality of second supports 323 are arranged at intervals along the height of the liner member 300. Furthermore, the plurality of first supports 333 and the plurality of second supports 323 are arranged flush with each other along the height of the liner member 300.

[0088] It should be understood that the first support body 333 and the second support body 323 are flush along the height direction of the box member 300, which means that the side of the first support body 333 used to support the storage shelf 400 is flush with the side of the second support body 323 used to support the shelf.

[0089] Please combine Figure 2 And refer to Figure 4 , Figure 4 The frame 330 includes two oppositely disposed transverse frames 331 and two oppositely disposed longitudinal frames 332 , the two longitudinal frames 332 being connected between the two transverse frames 331 and extending along the height direction of the box member 300 .

[0090] Each first support body 333 includes two first sub-support bodies 333a. The two first sub-support bodies 333a of the same first support body 333 are respectively arranged on the two longitudinal frames 332, and the two first sub-support bodies 333a are flush with each other along the height direction of the box liner member 300. It can be understood that the two first sub-support bodies 333a are flush with each other along the height direction of the box liner member 300, which means that the two first sub-support bodies 333a are flush with each other on their respective sides for supporting the storage shelves 400.

[0091] That is to say, the first support body 333 includes two parts, one part is arranged on one of the longitudinal frames 332, and the other part is arranged on the other opposite longitudinal frame 332, so that when the storage shelf 400 is placed in the storage cavity 300a, the two diagonals of the storage shelf 400 close to one end of the frame 330 are respectively supported by the support structures on the two longitudinal frames 332, which can ensure that the storage shelf 400 is firmly placed in the storage cavity 300a.

[0092] For more details, please refer to Figure 2 and Figure 4 The longitudinal frame 332 includes a first frame wall 3321. When the surrounding frame 330 is connected to the gallbladder body 310, the first frame wall 3321 is parallel or approximately parallel to the first side wall 310c (or second side wall 310d) of the gallbladder body 310, and the first sub-support body 333a is arranged on the first frame wall 3321 of the longitudinal frame 332.

[0093] Please refer to Figure 5 and Figure 6 , Figure 5 This is a first cross-sectional view of a box liner component according to an embodiment of the present invention. Figure 6 for Figure 5 A partial enlarged view of point A in the middle. The first sub-support body 333a includes a support body 3331 and a first blocking portion 3332. The support body 3331 includes a first support surface 3331a for supporting the storage shelf 400. The first blocking portion 3332 is connected to the end of the support body 3331 away from the back panel 320 and protrudes from the first support surface 3331a.

[0094] It can be understood that the first sub-support body 333a mainly plays a supporting and bearing role through the first supporting surface 3331a of the supporting body 3331, and can cooperate with the second supporting body 323 to support the storage shelf 400 in the storage cavity 300a.

[0095] The first blocking portion 3332 is connected to the end of the support body 3331 away from the back panel 320, and the first blocking portion 3332 protrudes from the first supporting surface 3331a (that is, the first blocking portion 3332 is higher than the first supporting surface 3331a). Then, when the storage shelf 400 is placed on the first sub-support body 333a, the first blocking portion 3332 is located at the end of the storage shelf 400 away from the back panel 320. The first blocking portion 3332 can limit the freedom of movement of the storage shelf 400 in the horizontal direction, and prevent the storage shelf 400 from slipping out of the storage cavity 300a and falling.

[0096] Thus, the storage shelf 400 can be stably placed in the storage cavity 300 a through the support of the support body 3331 and the limitation of the storage shelf 400 by the first blocking portion 3332 .

[0097] Please continue to refer to Figure 5 and Figure 6 The first sub-support body 333a may further include a second blocking portion 3333, which is connected to the first blocking portion 3332 and is arranged relative to the support body 3331 to form a first card slot 3334 for inserting the storage shelf 400.

[0098] To achieve the arrangement of the second blocking portion 3333 relative to the support body 3331, the second blocking portion 3333 is connected to the side of the first blocking portion 3332 near the back panel 320 and extends a certain distance toward the back panel 320. Therefore, when one end of the storage shelf 400 is inserted into the first slot 3334, the second blocking portion 3333 is positioned above the storage shelf 400. The second blocking portion 3333 also serves to limit the vertical freedom of the storage shelf 400, preventing the storage shelf 400 from bouncing up and down due to vibration. This prevents the storage shelf 400 from vibrating during transportation, which could cause deformation or breakage.

[0099] In one embodiment, the first support body 333 and the longitudinal frame 332 are an integral structure. For example, the entire surrounding frame 330 can be integrally formed, and the first support body 333 can be a structure directly formed on the longitudinal frame 332 by shaping.

[0100] Specifically, the frame 330 can be integrally molded using injection molding. The shape of the frame 330 is relatively complex, and the use of injection molding to integrally mold the frame 330 eliminates the need for connecting the transverse frame 331 to the longitudinal frame 332. This simplifies production and improves efficiency for mass production, while also ensuring a secure connection between the longitudinal frame 332 and the transverse frame 331. Furthermore, since the frame 330 is not only connected to the outer shell of the refrigeration unit 10 but also bears a portion of the weight of the shelves and stored items, the frame 330 must possess sufficient overall strength to prevent deformation. Using injection molding to mold the integral frame 330 ensures that the frame 330 meets these strength requirements.

[0101] Of course, in other optional embodiments of the present application, the first support body 333 may also be a split structure that is detachably connected to the surrounding frame 330 .

[0102] In one embodiment, the back plate 320 may be formed by integral vacuum molding.

[0103] The back panel 320 is formed using a vacuum forming process. This process allows for good stretchability, making it easy to form boss structures on the back panel 320 for the storage shelves 400 or other components. In particular, higher boss structures can be formed, ensuring a greater overlap between the storage shelves 400 and the boss structures, increasing the support area and improving the stability of the support for the storage shelves 400.

[0104] Please refer to Figure 7 , Figure 7The figure shows the structure of the back panel according to an embodiment of the present invention. The second support body 323 includes a first protrusion 3231 and a second protrusion 3232. The first protrusion 3231 is provided on the surface of the back panel 320, while the second protrusion 3232 is provided on the surface of the back panel 320. The second protrusion 3232 is spaced apart from the first protrusion 3231 along the height of the liner member 300, forming a second slot 3233 for the storage shelf 400 to be inserted into.

[0105] It can be understood that the first protrusion 3231 and the second protrusion 3232 are arranged at intervals along the height direction of the box liner component 300, that is, one of the protrusions is located on the upper side of the other protrusion. Taking the second protrusion 3232 stacked on the upper side of the first protrusion 3231 as an example, then the first protrusion 3231 is used to support and bear the storage shelf 400, and the first protrusion 3231 can be provided with a second supporting surface (not marked) for supporting the storage shelf 400.

[0106] The second protrusion 3232 and the first protrusion 3231 are spaced apart to form a second slot 3233, which can limit the storage shelf 400. When the storage shelf 400 is inserted into the second slot 3233, the second protrusion 3232 is located above the storage shelf 400. The second protrusion 3232 can limit the freedom of movement of the storage shelf 400 in the vertical direction, thereby preventing the storage shelf 400 from jumping up and down due to vibration, and preventing the user from accidentally touching the storage shelf 400 and accidentally lifting the storage shelf 400, thereby causing items on the storage shelf 400 to fall.

[0107] Since the storage shelf 400 is mainly supported by the protrusions located on the lower side, the height of the protrusion located on the upper side of the first protrusion 3231 and the second protrusion 3232 protruding from the surface of the back plate 320 can be less than the height of the other protrusion located on the lower side protruding from the surface of the back plate 320. Specifically, taking the example of the second protrusion 3232 being stacked on the upper side of the first protrusion 3231, the height of the second protrusion 3232 protruding from the surface of the back plate 320 is less than the height of the first protrusion 3231 protruding from the surface of the back plate 320.

[0108] Of course, in other optional embodiments of the present application, the second support body 323 may only include the first protrusion 3231, the first protrusion 3231 is protruded from the surface of the back panel 320, and the first protrusion 3231 has a second supporting surface for supporting the storage shelf 400.

[0109] In order to stably support the storage shelf 400 in the storage cavity 300a, each second support body 323 may include at least one set of the first protrusion 3231 and the second protrusion 3232. For ease of description, the combination of the first protrusion 3231 and the second protrusion 3232 is defined as a support group.

[0110] In one embodiment, if Figure 7 As shown, each second support body 323 includes two support groups, which are spaced apart in the horizontal direction and have the same distance from the center plane of the back plate 320 (or the two support groups are symmetrically arranged about the center plane of the back plate 320).

[0111] In another embodiment, each second support body 323 includes a support group, and the support group is disposed in the middle of the back plate 320 so that the center plane of the back plate 320 can pass through the support group.

[0112] Please refer to Figure 8 and Figure 9 , Figure 8 Schematic diagram of the structure of the gallbladder body according to an embodiment of the present invention, Figure 9 This is a schematic diagram of a gallbladder body before the first and second gallbladder shells are joined together in an embodiment of the present invention. In one embodiment, the gallbladder body 310 comprises a first gallbladder shell 311 and a second gallbladder shell 312 joined together along the height of the bladder member 300. The first gallbladder shell 311 comprises a top panel 3111 and first and second side panels 3112 and 3113 connected to opposite sides of the top panel 3111. The second gallbladder shell 312 comprises a bottom panel 3121 and third and fourth side panels 3122 and 3123 connected to opposite sides of the bottom panel 3121. The first and third side panels 3112 and 3122 join to form the first sidewall 310c, while the second and fourth side panels 3113 and 3123 join to form the second sidewall 310d.

[0113] like Figure 9 As shown, the first bladder shell 311 is in an inverted U shape as a whole, and the second bladder shell 312 is in a right U shape as a whole. The first bladder shell 311 and the second bladder shell 312 can be formed by a bending process.

[0114] By configuring the bladder body 310 to be composed of the aforementioned first and second bladder shells 311, 312, rather than connecting the four walls of the bladder body 310 with corresponding metal plates, the assembly steps for the bladder body 310 can be reduced, facilitating the production of the bladder body 310 and improving production efficiency. Furthermore, the aforementioned "U"-shaped design of the first and second bladder shells 311, 312 allows them to be formed using a bending process, thereby enhancing the overall strength of the bladder body 310 and preventing deformation of the bladder body 310.

[0115] Please combine Figure 9 And refer to Figure 10 , Figure 10 for Figure 9A partial enlarged view of point D in the middle. A first flange 3114 is provided on the end of the first shell 311 near the second shell 312, and a second flange 3124 is provided on the end of the second shell 312 near the first shell 311. The first flange 3114 and the second flange 3124 face opposite directions, and the first shell 311 and the second shell 312 are fastened together by the first flange 3114 and the second flange 3124.

[0116] like Figure 10 As shown, the first flange 3114 can be formed by bending the end of the first gallbladder shell 311, and the second flange 3124 can be formed by bending the end of the second gallbladder shell 312. By setting the first flange 3114 and the second flange 3124 to face opposite directions, that is, bending the first flange 3114 and the second flange 3124 in opposite directions respectively, the first flange 3114 and the second flange 3124 can be interlocked.

[0117] The first flange 3114 can face the interior of the bladder body 310 (i.e., bend inward), and the second flange 3124 can face the exterior of the bladder body 310 (i.e., bend outward). Alternatively, the first flange 3114 can face the exterior of the bladder body 310, and the second flange 3124 can face the interior of the bladder body 310. It should be noted that the drawings of this embodiment are merely illustrative of the latter option and are not intended to limit the present application.

[0118] Specifically, when the bladder body 310 is spliced, the first flange 3114 and the second flange 3124 can be pressed and fastened together by a punching machine, and the first flange 3114 and the second flange 3124 are pressed tightly together by the punching pressure, which can ensure the firmness of the connection between the first bladder shell 311 and the second bladder shell 312.

[0119] In another embodiment of the present application, the bladder body 310 may also be formed by integrally bending a single piece of metal plate.

[0120] Please refer to Figure 8 The bottom plate 3121 (or bottom wall 310b) is provided with a drain port 3121a, which is used to drain the defrost water in the liner body 310 to the outside of the liner member 300. It will be understood that the drain port 3121a is provided at the lowest point of the bottom plate 3121, so that the defrost water in the liner body 310 flows to the drain port 3121a under gravity. Specifically, the bottom plate 3121 can be formed by stamping the bottom wall 310b to form multiple inclined surfaces that tilt from the ends of the bottom plate 3121 toward the center. The junction of the multiple inclined surfaces is the lowest point of the bottom plate 3121, and the drain port 3121a is punched out at this location.

[0121] In one embodiment, please combine Figure 5 And refer to Figure 11 , Figure 11 for Figure 5 A partial enlarged view of point B in the middle. A first folded edge 3101 is provided at one end of the bladder body 310 close to the back plate 320 . The first folded edge 3101 is folded and abuts against the outer surface of the bladder body 310 .

[0122] As can be understood, providing the first folded edge 3101 at the end of the bladder body 310 near the back plate 320 increases the local thickness of the bladder body 310, thereby enhancing the overall strength of the bladder body 310, preventing deformation of the bladder body 310 due to the large squeezing force during the foaming process of the refrigeration device 10, and avoiding unevenness of the four walls of the bladder body 310. Furthermore, providing the first folded edge 3101 at the end where the bladder body 310 connects to the back plate 320 increases the thickness of the bladder body 310 at the edge, and the increased thickness of the bladder body 310 at the edge does not affect the thickness of the main body of the insulation layer.

[0123] In another embodiment, please combine Figure 5 And refer to Figure 12 , Figure 12 for Figure 5 A partial enlarged view of point C in the middle. A second folded edge 3102 is provided at one end of the bladder body 310 close to the surrounding frame 330 . The second folded edge 3102 is folded and abuts against the outer surface of the bladder body 310 .

[0124] Similarly, by providing a second folded edge 3102 at one end of the bladder body 310 near the frame 330, the local thickness of the bladder body 310 is increased, further enhancing the overall strength of the bladder body 310. This further prevents deformation of the bladder body 310 due to the extrusion force of the foaming process during the refrigeration device 10, and better ensures the flatness of the four walls of the bladder body 310. Furthermore, providing the second folded edge 3102 at the end where the bladder body 310 connects to the frame 330 only increases the thickness of the other end of the bladder body 310 and does not affect the thickness of the main insulation layer.

[0125] Please refer to Figure 7 and Figure 11 The back plate 320 includes a plate body 321 and a rim 322 surrounding the outer periphery of the plate body 321 , and the rim 322 is arranged around one end where the body 310 and the back plate 320 are connected.

[0126] Because the back panel 320 is formed using a vacuum forming process, it is relatively thin. By providing a rim 322 around the outer periphery of the back panel 320 body 321, the overall strength of the back panel 320 is enhanced, the load-bearing capacity of the back panel 320 is increased, and the back panel 320 is prevented from easily deforming. Furthermore, the rim 322 surrounds the outer periphery of the back panel 320 body 321, providing a positioning function. This not only facilitates the connection of the back panel 320 to the bladder body 310, but also, by surrounding one end of the bladder body 310, strengthens the seal between the back panel 320 and the bladder body 310. The rim 322 isolates the foaming liquid from the joint between the bladder body 310 and the back panel 320, preventing the foaming liquid from entering through the gap between the back panel 320 and the bladder body 310.

[0127] Specifically, the back plate 320 and the body 310 may be connected and sealed using a sealant such as BOPP glue.

[0128] Please refer to Figure 5 and Figure 12 A positioning groove 334 is provided on the side of the surrounding frame 330 facing the gallbladder body 310 , and the end of the gallbladder body 310 connected to the surrounding frame 330 is inserted into the positioning groove 334 .

[0129] It can be understood that the positioning groove 334 plays a guiding and positioning role in the connection and assembly of the gallbladder body 310 and the surrounding frame 330, so that the gallbladder body 310 can quickly find the position for splicing with the surrounding frame 330, thereby improving the assembly efficiency; at the same time, the positioning groove 334 can also play a limiting role on the gallbladder body 310. During the assembly process, the positioning groove 334 can prevent the gallbladder body 310 from moving, and through the limitation of the gallbladder body 310 by the positioning groove 334, the firmness of the connection between the gallbladder body 310 and the surrounding frame 330 can be ensured.

[0130] The positioning groove 334 is designed to be annular around the entire frame 330 so that the top wall 310a, the top wall 310a, the first side wall 310c and the second side wall 310d of the body 310 are all inserted into the positioning groove 334.

[0131] Specifically, after one end of the bladder body 310 and the surrounding frame 330 is inserted into the positioning groove 334 , a sealant such as BOPP glue can be used to fill the positioning groove 334 to connect and seal the bladder body 310 and the surrounding frame 330 .

[0132] Please refer again Figure 8 A water retaining rib 3121b is protruded from one side of the bottom wall 310b close to the frame 330, and the water retaining rib 3121b extends from one end of the bottom wall 310b close to the first side wall 310c to one end close to the second side wall 310d.

[0133] The water retaining rib 3121b is arranged close to the frame 330 to block the defrost water on the gallbladder body 310 from flowing toward the frame 330, thereby preventing the defrost water from flowing from the gap between the frame 330 and the gallbladder body 310 to the anti-condensation pipe outside the frame 330, thereby preventing the anti-condensation pipe from being corroded and damaged.

[0134] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
