In this way, the fixing portion 33 can make full use of the side wall of the door body 2 to realize the fixed connection between the fixing portion 33 and the door body 2, and reasonably utilize the space in the door body 2, thereby increasing the space utilization rate in the door body 2.

[0084] In some embodiments, the mounting base 3 can comprise a connecting portion 32. The connecting portion 32 can be arranged in the door body 2, and the connecting portion 32 extends from the mounting portion 31 towards the fixing portion 33. The fixing portion 33 can be arranged at one end of the connecting portion 32 away from the mounting portion 31. The connecting portion 32 can be arranged between the fixing portion 33 and the mounting portion 31. The connecting portion 32 is used to connect the mounting portion 31 and the fixing portion 33. In this way, the connection between the fixing portion 33 and the mounting portion 31 can be realized, so that the mounting portion 31 can be fixed in the door body 2 by means of the fixing portion 33.

[0085] Please continue to refer to Figures 2 to 5 As shown, in some embodiments, the mounting portion 31, the connecting portion 32 and the fixing portion 33 are integrally connected. In this way, on the one hand, the mounting base 3 is integrally formed by the mounting portion 31, the connecting portion 32 and the fixing portion 33, and does not need to be assembled by multiple components, thereby ensuring the overall stability of the mounting base 3 and avoiding structural defects caused by assembly, which can cause the mounting base 3 to fail to meet the vacuumizing requirement. On the other hand, the mounting base 3 is integrally formed, thereby saving the work of assembling the mounting base 3. This reduces the economic and manpower cost. Finally, the mounting base 3 is connected with the side wall of the door body 2 and the mounting cover plate 4, respectively, thereby enhancing the fixing strength of the mounting base 3 in the door body 2, and further avoiding disconnection with the door body 2 to cause failure, which greatly improves the quality standard of the refrigeration equipment and enables the user to have a better use experience.

[0086] Please continue to refer to Figures 2 to 5As shown, in some embodiments, the door body 2 can include a door main body 21 and a door tank 22. The door main body 21 can be arranged on the side of the door body 2 away from the storage chamber. The door tank 22 can be arranged on the side of the door body 2 facing the storage chamber. The door tank 22 and the door main body 21 can be arranged to form a foaming cavity 23. In this way, by arranging the foaming cavity 23 in the refrigeration device, the temperature exchange between the storage chamber and the outside can be better prevented, and the need for more electrical energy to maintain the temperature inside the storage chamber can be avoided.

[0087] In some embodiments, the mounting base 3 can be arranged in the foaming cavity 23. In this way, by arranging the mounting base 3 in the foaming cavity 23, the idle space of the refrigeration device can be better utilized.

[0088] In some embodiments, the fixing portion 33 of the mounting base 3 is fixedly connected with the side wall of the door main body 21. The fixing portion 33 is fixedly connected with the side wall of the door main body 21, which can better stabilize the mounting base 3 and avoid loosening or falling of the mounting base 3 to cause failure to complete vacuumization.

[0089] Figure 6 is Figure 5 a partial structural schematic view.

[0090] Please refer to Figures 2 to 6 As shown, in some embodiments, the door main body 21 can include a door front plate 211. The door front plate 211 can be arranged on the side of the door main body 21 away from the storage chamber. The door front plate 211 can be arranged at intervals on the side of the door tank 22 away from the storage chamber, and the foaming cavity is arranged between the door front plate 211 and the door tank 22.

[0091] In some embodiments, the door main body 21 can include a door side plate 212. The door side plate 212 is arranged to extend from the door front plate 211 towards the storage chamber. The door side plate 212 can be connected with the door front plate 211 and the door tank 22, and the fixing portion 33 is fixedly connected with the door side plate 212. In this way, the mounting base 3 is connected with the door side plate 212 through the fixing portion 33. In this way, by fixing the fixing portion 33 to the door side plate 212, the mounting base 3 can be more conveniently installed, the time for producing and installing the refrigeration device can be reduced, the efficiency for producing and installing the refrigeration device can be improved, and the labor cost for installation can be indirectly reduced.

[0092] In some embodiments, the door front plate 211 can serve as the front side wall of the door body 2. The door side plate 212 can serve as the left side wall or the right side wall of the door body. For example, two door side plates 212 can be arranged. One door side plate 212 extends rearward from the left edge of the door front plate 211, and the other door side plate 212 also extends rearward from the right edge of the door front plate 211.

[0093] Figure 7 is Figure 6 a structural schematic view of A in FIG. 5.

[0094] Please refer to Figures 6 to 7 As shown, in some embodiments, the fixing part 33 can be arranged parallel to the door side plate 212, so as to make the fixing part 33 connect to the door side plate 212 at one side of the door side plate 212. In this way, by increasing the connection area between the fixing part 33 and the door side plate 212, the fixing degree of the fixing part 33 and the door side plate 212 is increased.

[0095] Please continue to refer to Figures 6 to 7 As shown, in some embodiments, the door side plate 212 is bent and extends in the direction of the door body 22 to form a flange 2121. The fixing part 33 can be connected to the flange 2121. In this way, on the one hand, connecting the fixing part 33 to the flange 2121 can avoid opening holes on the door front plate 211 and the door body 22 or adding other structures for mounting the mounting base 3, which makes the temperature insulation effect of the foaming cavity 23 in the door body 2 stronger. On the other hand, by avoiding processing or adding other structures for mounting the mounting base 3 on the door front plate 211 or the door body 22, the manufacturing cost of the refrigeration equipment is reduced.

[0096] In some embodiments, the flange 2121 can be arranged at the edge of the door side plate 2121 away from the door front plate. The flange 2121 extends along the extension direction of the door side plate 2121.

[0097] In some embodiments, the flange 2121 can be in a strip shape. The flange 2121 can also be in other shapes.

[0098] Please continue to refer to Figures 6 to 7 As shown, in some embodiments, when the fixing part 33 is mounted to the door side plate 212, the side of the fixing part 33 away from the door side plate 212 can be flush with the flange 2121 within a certain range. In this way, the contact area of the fixing part 33 and the door side plate 212 can be increased, and the connection relationship between the fixing part 33 and the door side plate is more stable. When the fixing part 33 is subjected to an impact force or a pressure force towards the door side plate 212, the fixing part 33 can help bear a larger impact force or pressure force.

[0099] Please continue to refer to Figure 6 and Figure 7 As shown, in some embodiments, the side of the fixing part 33 towards the flange can abut against the flange 2121. The side of the fixing part 33 towards the door front plate 211 can abut against the door front plate 211. This makes the connection of the fixing part 33 and the door body 2 more stable. In this way, when the mounting base 3 is subjected to an external force, the fixing part 33, the door front plate 211 and the flange 2121 can abut against each other respectively, so as to unload the force through the door front plate 211 and the flange 2121, thereby preventing the mounting base 3 from shaking, and ensuring that the mounting base 3 does not malfunction or be damaged.

[0100] Please continue to refer to Figure 6 And Figure 7 As shown in FIG. 12, in some embodiments, the fixed part 33 is arranged in parallel with the turn-up 2121 on one side of the turn-up 2121, and the fixed part 33 is arranged in parallel with the door front plate 211 on one side of the door front plate 211. In this way, the abutting area between the turn-up 2121, the door front plate 211 and the fixed part 33 is increased, thereby further stabilizing the connection between the fixed part 33 and the door body 2.

[0101] Figure 8 is an exploded view of Figure 6

[0102] As shown in FIG. 13, in some embodiments, the turn-up 2121 can be provided with a first clamping hole 2122. The fixed part 33 can be provided with a first clamping buckle 331, and the first clamping buckle 331 can be fixedly connected with the first clamping hole 2122. In this way, the strength of the connection between the fixed part 33 and the turn-up 2121 can be increased. Figure 8 As shown in FIG. 14, in some embodiments, the turn-up 2121 can be provided with a plurality of first clamping holes 2122. The fixed part 33 can be provided with a plurality of first clamping buckles 331. The first clamping holes 2122 and the first clamping buckles 331 can be connected. For example, the first clamping buckle 331 is inserted through the first clamping hole 2122, so as to realize the fixed connection of the first clamping buckle 331 and the first clamping hole 2122. In this way, by respectively arranging the first clamping buckle 331 on the fixed part 33 and the first clamping hole 2122 on the turn-up 2121, the fixed part 33 and the door side plate 212 can be more stably connected, and the installation of the base 3 in the door body 2 is more convenient.

[0103] Figure 8 In some embodiments, the first clamping hole 2122 can be rectangular. The first clamping hole 2122 can be of other shapes, and the first clamping buckle 331 has a corresponding shape so as to enable the first clamping buckle 331 to be fixedly connected with the first clamping hole 2122. In this way, the particularity of various processing techniques can be met, thereby reducing the cost of the refrigeration equipment.

[0106] Figures 8 to 10 ​​​​As shown, in some embodiments, the flange 2121 can be provided with a limiting hole 2123. The fixing portion 33 can be provided with a limiting portion 332. The limiting portion 332 can be connected with the limiting hole 2123, for limiting the position of the fixing portion 33. When the limiting hole 2123 is connected with the limiting portion 332, the first buckle 331 can be connected with the first clamping hole 2122 correspondingly. Thus, when the limiting hole 2123 is connected with the limiting portion 332, the first buckle 332 can be connected with the first clamping hole 2122 correspondingly, which makes the first buckle 331 and the first clamping hole 2122 connected only by aligning the limiting hole 2123 and the limiting portion 332 when installing the mounting base 3, and further makes the installation of the mounting base 3 more convenient, and greatly improves the installation efficiency of the mounting base 3.

[0107] Please refer to Figures 8 to 10 As shown, in some embodiments, the flange 2121 can be provided with at least a plurality of limiting holes 2123. The fixing portion 33 can be provided with a plurality of limiting portions 332. Thus, the position of the fixing portion 33 can be more conveniently limited.

[0108] In other embodiments, the limiting hole 2123 is a groove or a through hole with an opening on one side. The opening of the limiting hole 2123 is located at the side edge of the flange away from the door side plate. The limiting portion 332 is protruded on the fixing portion 33, and the limiting portion 332 enters from the opening of the limiting hole 2123 to complete the limiting of the fixing portion 33. Thus, the particularity of various processing techniques can be met, and the cost of the refrigeration equipment can be reduced. And the limiting portion 332 and the limiting hole 2123 can be more conveniently connected.

[0109] Please continue to refer to Figure 10 As shown, in some embodiments, the fixing portion 33 can be provided with a through hole. Thus, the material cost of the mounting base 3 can be reduced by providing the through hole, and the buffering performance and strength of the fixing portion 33 can be increased by providing the through hole on the fixing portion 33.

[0110] In some embodiments, the fixing portion 33 can be provided with a plurality of through holes.

[0111] In some embodiments, the fixing portion 33 can be provided with a plurality of uniformly distributed through holes.

[0112] In some embodiments, the fixing portion 33 can be provided with a plurality of uniformly distributed through holes. The axial direction of the through holes on the fixing portion 33 forms an approximately right angle with the plane in which the front plate 211 is located. It should be noted that approximately right angle means that it is equivalent to a right angle within a certain angle error range. The angle error range can be specified by industry standards or set by the manufacturer. For example, 90 degrees plus or minus 5 degrees is considered a right angle. In this way, the axial direction of the through holes on the fixing portion 33 forms an approximately right angle with the plane in which the front plate 211 is located, and because the two sides of the through holes on the fixing portion 33 abut the flange 2121 and the front plate 211 respectively, this can increase the support between the fixing portion 33 and the flange 2121, as well as the support between the fixing portion 33 and the front plate 211, so that the fixing portion is less likely to deform.

[0113] In some embodiments, the refrigeration device can further include an adhesive member 6. The adhesive member 6 can be arranged between the fixing portion 33 and the door side plate 212. The adhesive member 6 is used to connect the fixing portion 33 and the door side plate 212, so as to fix the mounting base 3 in the door body 2. In this way, the fixing portion is connected with the flange 2121, and at the same time the adhesive member 6 connects the fixing portion 33 and the door side plate 212, achieving double connection of the fixing portion 33, enhancing the connection relationship between the mounting base 3 and the door side plate 212, and further making the fixing effect of the mounting base 3 better.

[0114] In some embodiments, the adhesive member 6 can be in the shape of a sheet. The adhesive member 6 has at least two sides with adhesive function. One side is connected with the fixing portion 33, and the other side is connected with the door side plate 212. In this way, the connection area between the adhesive member 6 and the fixing portion 33 and the door side plate 212 respectively can be increased, and the connection relationship between the fixing portion and the door side plate is more stable.

[0115] In other embodiments, the adhesive member 6 can also be in the shape of a strip or other shapes.

[0116] Please refer to Figures 8 to 10 In some embodiments, the connecting portion 32 can include a connecting arm 321, as shown. The connecting arm 321 extends from the fixing portion 33 towards the mounting portion 31. One end of the connecting arm 321 can be integrally connected with the fixing portion 33.

[0118] In some embodiments, the receiving arm 322 in the mounting base 3 abuts against the mounting cover plate 4, and clamps at least part of the door cylinder 22 between the receiving arm 322 and the mounting cover plate 4. In this way, by arranging the receiving arm 322 bending towards the direction close to the door cylinder 22, and abutting against the mounting cover plate 4, when the mounting cover plate 4 shakes, the mounting cover plate 4 can be prevented from being detached or loosened by the force generated at the abutting position between the receiving arm 322 and the mounting cover plate 4. The abutting of the receiving arm 321 and the mounting cover plate 4 can greatly increase the stability of the mounting of the mounting cover plate 4.

[0119] Please refer to Figures 11 to 13 In some embodiments, the mounting cover plate 4 can be provided with a limiting rib 44. The limiting rib 44 can be arranged at the edge of the mounting cover plate 4.

When the mounting cover plate 4 is arranged covering the mounting port 221, the receiving arm 322 in the mounting base 3 abuts against at least part of the limiting rib 44, and clamps at least part of the door cylinder 22 between the receiving arm 322 and the limiting rib 44. In this way, when the mounting cover plate 4 is arranged covering the mounting port 221, the limiting rib 44 is arranged adhering to the circumferential edge of the mounting port 221, so that at least part of the limiting rib 44 abuts against the receiving arm 324. The mounting cover plate 4 and the mounting base 3 can generate force to each other through the abutting part, and rely on each other, thereby increasing the connection stability between the mounting cover plate 4 and the mounting base 3.

[0121] In some embodiments, the side edge of the mounting portion 31 facing the door cylinder 22 can abut against the door cylinder 22. In this way, the support force can be formed between the mounting portion 31 and the door cylinder 22, so that the mounting portion 31 is more stable in the door body 2.

[0122] In some embodiments, the installation portion can abut against at least part of the limiting rib 44 at a side edge of the door pocket 22. When the installation cover plate 4 is covered on the installation opening 221, the limiting rib 44 is attached to the peripheral side edge of the installation opening 221, and at least part of the door pocket 22 is clamped between the installation portion 31 and the limiting rib 44, so that at least part of the limiting rib 44 abuts against the installation portion 31. In turn, the installation cover plate 4 and the installation portion 31 can generate a force of action on each other through the abutting portion, and rely on each other, thereby increasing the stability.

[0123] Referring to Figures 8 to 10 As shown, in some embodiments, the connecting portion 32 can further be provided with a first reinforcing rib 323. The first reinforcing rib 323 can be provided on a side of the connecting arm 321 facing the door pocket 22.

One end of the first reinforcing rib 323 can be integrally connected with the fixed portion 33. The other end of the first reinforcing rib 323 can be connected with the installation portion 31. In this way, the first reinforcing rib 323 can increase the strength of the connecting arm 321, and in turn increase the connection stability between the fixed portion 33 and the installation portion 31.

[0124] In some embodiments, the connecting portion 32 can further include a second reinforcing rib 324. The second reinforcing rib 324 can be provided on a side of the receiving arm 322 away from the door pocket 22. The second reinforcing rib 324 extends and is arranged in a direction from the connecting arm 321 to the fixed portion 33. One end of the second reinforcing rib 324 can be integrally connected with the installation portion 31. The other end of the second reinforcing rib 324 can be integrally connected with the first reinforcing rib 323. One end of the first reinforcing rib 323 can be integrally connected with the second reinforcing rib 324. The other end of the first reinforcing rib 323 can be integrally connected with the fixed portion 33. In this way, by providing the first reinforcing rib 323 and the second reinforcing rib 324 on the connecting portion 32, the strength of the connecting portion 32 can be increased, and the strength of the entire installation base 3 can be further improved. In addition, the first reinforcing rib 323 is provided on the side of the connecting arm 321 facing the door pocket 22, and is connected with the fixed portion 33 and the receiving arm 322 respectively, which can improve the ability of the installation base 3 to withstand the force in the direction of the door pocket 33. The second reinforcing rib 324 is provided on the side of the receiving arm 322 away from the door pocket 22, which can improve the ability of the installation base 3 to withstand the force in the direction of the door front plate 211. The strength of the installation base 3 is greatly increased.

[0125] In other embodiments, the first reinforcing rib 323 is in a ridge shape, and the first reinforcing rib 324 forms a right angle with the fixed portion 33. In this way, a stronger support force can be generated on the fixed portion 33.

[0126] In other embodiments, the second reinforcing rib 324 is in a ridge shape, and the second reinforcing rib 324 forms a right angle with the installation portion 31. In this way, a stronger support force can be generated on the installation portion 31.

The abutment portion 314 extends from the mounting portion 31 toward the front panel 211, with one end of the abutment portion 314 abutting against the front panel 211. This allows the mounting base 3 to be supported by the front panel, thereby further securing the mounting base 3 within the door body 2.

[0128] In some embodiments, one end of the abutment portion 314 is integrally connected to the side of the mounting portion 31 facing the front panel 211. The other end of the abutment portion 314 abuts against the front panel 211.

[0129] Please see Figure 5 As shown, in some embodiments, a mounting cavity 311 may be formed on the mounting part 31. The mounting cavity 311 may face the door frame 22. A mounting cover 4 may be placed on the mounting cavity 311 so that the mounting base 3 is connected to the mounting cover 4, thereby allowing the mounting cover 4 to cover the side of the door frame 22 facing the storage compartment. In this way, by connecting the mounting cover 4 and the mounting base 3 through the mounting cavity 311, the assembly between the mounting cover 4 and the mounting base 3 can be made more convenient.

[0130] Please continue reading. Figures 8 to 10 As shown, in some embodiments, the mounting cavity 311 may include a first sub-cavity 3111 for housing the air extraction pipe.

[0131] In some embodiments, the mounting cavity 311 may include a second sub-cavity 3112, which is used to place the wires controlling the opening and closing of the vacuum pumping function.

[0132] In some embodiments, when the mounting cover 4 is connected to the mounting base 3, the switch assembly 7, the snap-fit ​​part 43, and the snap-fit ​​arm 45 are partially embedded in the second cavity 3112.

[0133] In some embodiments, the first chamber 3111 and the second chamber 3112 may be formed side by side on the mounting portion 311. This allows for a more rational layout of the piping used for evacuation and the wiring used for control, preventing malfunctions in the vacuuming function of the refrigeration equipment due to entanglement.

[0134] Please see Figures 2 to 10As shown, in some embodiments, the first sub-cavity 3111 is formed with a first duct 3113 that communicates between the inside and outside of the first sub-cavity 3111.

One end of the first duct 3113 is in communication with the vacuumizing device 8 through the suction pipe 91. The other end of the first duct 3113 is connected with the suction joint 5 through the transfer pipe 92. In this way, when the mounting base 3 and the mounting cover plate 4 are fixedly connected, the entire suction pipe 9 can pass through the mounting base 3 through the first duct 3113, the transfer pipe 92 and the suction pipe 91, so as to realize the closed communication between the vacuumizing device 8 and the suction joint 5.

[0135] Please refer to Figures 11 to 13 As described, in some embodiments, the suction joint 5 can be formed with a sealed space, and the sealed space has two openings, i.e. a first opening 51 and a second opening 52. The transfer pipe 92 can be in communication with the first opening 51. The vacuum preservation box 10 can be in communication with the second opening 52. In this way, the vacuum environment is formed by extracting the gas from the vacuum preservation box 10.

[0136] Please refer to Figures 2 to 10 As shown, the second sub-cavity 3112 is formed with a second duct 3114. The second duct 3114 communicates between the inside and outside of the second sub-cavity 3112. The refrigeration device can include a wire provided in the foaming cavity 23, and the wire electrically connects the vacuumizing device 8 and the switch assembly 7 to control the opening and closing of the vacuumizing device 8. One end of the wire is electrically connected with the vacuumizing device 8. The other end of the wire enters the second sub-cavity 3112 through the second duct 3114 and is in communication with the switch assembly 7. In this way, the wire is directly connected with the switch assembly 7 through the second duct 3114, without the need for the connection between the wires, thereby reducing the probability of control failure.

[0137] Figure 11 is Figure 3 Please refer to Figure 9 and Figure 12 As shown, in some embodiments, the side wall of the mounting cavity 311 can be provided with a second buckle 312. The mounting cover plate 4 can be provided with an extension 41, and the extension 41 can be provided with a second clamping hole 411. When the mounting cover plate 4 is provided on the mounting cavity 311, the second buckle 312 and the second clamping hole 411 can be connected. In this way, through the connection between the second buckle 312 and the second clamping hole 411, the mounting cover plate 4 and the mounting base 3 can be further fixedly connected.

[0138] Please continue to refer to Figure 9 and Figure 11As shown, in some embodiments, a third clamping hole 313 can be arranged on the side wall of the mounting cavity 311. The first sub-cavity 3111 and the second sub-cavity 3112 share a common side wall. The third clamping hole 313 can be arranged on the common side wall. In this way, the connection relationship between the mounting base 3 and the mounting cover plate 4 can be further stabilized.

[0139] In the above embodiment, the vacuumizing device 8 is in communication with one end of the first pipe 3113 through the air extraction pipeline 91, the other end of the first pipe 3113 is in communication with one end of the transfer pipeline 92, and the other end of the transfer pipeline 92 is in communication with the first opening 51 of the air extraction joint 5. The second opening 52 of the air extraction joint 5 can be in communication with the vacuum preservation box 10. When the vacuumizing device starts to extract gas, the gas is sequentially discharged from the vacuum preservation box 10, the transfer pipeline 92, the first pipe 3113, the air extraction pipeline 91, the vacuumizing device 8, so as to create a low-pressure environment in the vacuum preservation box 10.

[0140] At the end of the vacuumizing process, the pressure in the vacuum preservation box is between one standard atmosphere and absolute vacuum. Since the air pressure in the vacuum preservation box is lower than the standard atmosphere, the skilled person also commonly refers to it as "vacuum storage", and this state in which the air pressure is lower than the standard atmosphere is called "vacuum state".
