[0022] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.
[0023] See also Figures 1 to 5 The figure shows a preferred embodiment of the utility model, which mainly relates to a refrigeration device 100, which includes a box body 1, and a door body 2 rotatably arranged on the front side of the box body 1. The door body 2 has a door body 21, a door handle 22 arranged on the open side of the door body 21, and a door seal 23 arranged around the side of the door body 21 facing the box body 1; the door seal 23 includes a door seal body 231 formed with a magnetic stripe bag 2312 and a magnetic stripe 232 arranged in the magnetic stripe bag 2312. The magnetic stripe 232 has a first part 2321 corresponding to the position of the door handle 22 and a second part 2322 other than the first part 2321, and the unit area of the first part 2321 is smaller than the unit area of the second part 2322.
[0024] The refrigeration device 100 of the present invention sets the area of the magnetic strip at the door handle 22 to be relatively small, so that when the door handle is pulled to open the door, the door body 21 and the door seal 23 have a slight deformation at the door handle 22. When the door opening force reaches a certain level, the door seal 23 at the position of the first part 2321 of the magnetic strip 232 will open first. At this time, the outside air enters the interior of the box body 1 to achieve internal and external air pressure balance, further realizing labor-saving door opening. In addition, this setting does not require the addition of additional air pressure balancing components and does not affect the sealing between the door body 2 and the box body 1, so it is low in cost and easy to implement.
[0025] Specifically, Figures 1 to 3 As shown, the box body 1 includes an inner liner 11 forming a storage compartment 10 , an outer shell 12 located outside the inner liner 11 , an insulation layer 13 arranged between the inner liner 11 and the outer shell 12 , and a cooling system 14 for cooling the storage compartment 10 .
[0026] Among them, the front end of the inner liner 11 is formed with a flange 111 outwardly, and the outer shell 12 extends inwardly to form a snap-on structure 121. The snap-on structure 121 and the flange 111 of the inner liner 11 are mutually clamped to form a front end face 15 located at the front end of the box body 1. The front end face 15 can be connected with the door seal 23 of the door body 2 to close the storage compartment 10.
[0027] The door body 21 comprises a door shell 211, a door lining 212 and a heat-insulating layer 213 disposed between the door shell 211 and the door lining 212. The middle portion of the door lining 212 opposite to the storage compartment 10 protrudes toward the storage compartment 10, and the side portions of both sides are connected to the door shell 211. The side portions of the door lining 212 are arranged in a step-like manner, so that the door lining 212 is in a step-like shape that gradually rises from the outside to the inside. The side portions of the door lining 212 are formed with a fixing groove 214 for fixing the door seal 23.
[0028] The door handle 22 is disposed on one side of the door body 2 extending in the height direction, is fixed on the door shell 211 , and is formed with a handle groove 221 recessed toward the heat-insulating layer 213 .
[0029] Combination Figure 3 and Figure 5 As shown, the door seal body 231 has an airbag portion 233 and a clamping portion 234 connected to one side of the airbag portion 233 and fixed to the door body 21. The clamping portion 234 is clamped in the fixing groove 214 to fix the door seal 23 on the door body 21.
[0030] The airbag portion 233 comprises a main airbag 235 disposed adjacent to the clamping portion 234, and the magnetic stripe bag 2312 and the auxiliary airbag 236 disposed side by side on the side of the main airbag 235 away from the clamping portion 234. The magnetic stripe bag 2312 is disposed closer to the outer edge of the door body 2 than the auxiliary airbag 236, so that the door seal 23 can be fixed to the box body 1 from the outer edge, thereby ensuring the sealing of the door body 2 when it is closed.
[0031] The magnetic stripe 232 is arranged in the magnetic stripe bag 2312. Specifically, the door seal 23 is distributed on the four side edges inside the door body 21, and the magnetic stripe 232 is also correspondingly arranged in the four-side door seal body 231. The first part 2321 of the magnetic stripe 232 is the part facing the door handle 22, and the magnetic stripe 232 other than the first part 2321 can be called the second part 2322; or, in this embodiment, in the longitudinally extending magnetic stripe 232 located on the same side of the door handle 22, the part corresponding to the position of the door handle 22 is called the first part 2321, and the rest is called the second part 2322; the magnetic stripes 232 in the other three side door seals 23 of the door body 2 are not compared, and can be adjusted and set accordingly according to the magnetic attraction requirements of the corresponding parts. Preferably, the extension length of the first part 2321 of the magnetic stripe 232 is less than the extension length of the door handle 22 to avoid affecting the suction force of the door body 23.
[0032] As a preferred embodiment of the present invention, “the unit area of the first portion 2321 is smaller than the unit area of the second portion 2322” is specifically configured as follows: a plurality of openings 2320 are formed on the first portion 2321. The shape and distribution of the openings 2320 are not limited.
[0033] Preferably, if Figure 4 As shown, in the width direction of the magnetic stripe 232, the opening 2320 is formed in the middle position of the first part 2321, and is arranged in a rectangular shape along the height direction of the door body 2, so that there are connecting structures on both sides of the opening to ensure the verticality of the magnetic stripe 232 and avoid bending of the magnetic stripe.
[0034] As another preferred embodiment of the present invention, Figure 6 As shown, the opening 2320 may also be formed in a notch shape on one side of the first portion 2321 and spaced apart along the height direction of the door 2 body.
[0035] Furthermore, in this embodiment, the opening 2320 is configured to be a rectangular shape extending longitudinally along the door body 2 , and the width of the opening 2320 in the magnetic strip width direction is not less than half of the width of the second portion 2322 .
[0036] like Figure 5 , and combined with Figure 2 As shown, the auxiliary airbag 236 includes a first auxiliary airbag 2361 arranged adjacent to the magnetic stripe bag 2312 and a second auxiliary airbag 2362 arranged adjacent to the first auxiliary airbag 2361, the volume of the first auxiliary airbag 2361 is smaller than the volume of the second auxiliary airbag 2362, and one end of the second auxiliary airbag 2362 away from the magnetic stripe bag 2312 protrudes toward the box body 1 beyond the magnetic stripe bag 2312 and the first auxiliary airbag 2361.
[0037] The overall width of the main airbag 235 is slightly smaller than the sum of the overall widths of the magnetic stripe bag 2312 and the auxiliary airbag 236. The main airbag 235 has two connection ends extending toward the box body 1, one of which is connected to the side of the magnetic stripe bag 2312 facing the door body 21, and the other is connected to the connection between the first auxiliary airbag 2361 and the second auxiliary airbag 2362, so that a floating gap 237 is formed between the magnetic stripe bag 2312 and the main airbag 235, and between the second auxiliary airbag 2362 and the main airbag 235.
[0038] Furthermore, the main airbag 235 is further provided with a supporting rib 2351 protruding toward the first auxiliary airbag 236, so that when the door body spacing is smaller than the design distance and there is a possibility of door seal separation, that is, when the door seal 23 is squeezed, the supporting rib 2351 can be supported on the first auxiliary airbag 236, and the main airbag 235 will not be forced to collapse inward, thereby effectively reducing the occurrence of door seal failure, ensuring the sealing performance of the door seal 23 and the door body, avoiding problems such as door seal leakage and condensation, and improving the user experience.
[0039] In addition, in this embodiment, the airbag portion 233 is further provided with fins 238 extending outward from both ends of one side of the main airbag 235 adjacent to the clamping portion 234 and from the side of the second auxiliary airbag 236. The fins 238 are used to abut against the inner wall surface of the door body 21 to enhance the sealing effect on both sides of the clamping portion 234.
[0040] In summary, the overall design of the refrigeration device 100 of the utility model is simple, convenient and versatile. By setting the area of the magnetic stripe at the door handle 22 to be relatively small, when the door handle is pulled to open the door, the door body 21 and the door seal 23 are slightly deformed at the door handle 22. When the door opening force reaches a certain level, the door seal 23 at the first part 2321 of the magnetic stripe 232 will open first. At this time, the outside air enters the interior of the box body 1 to achieve internal and external air pressure balance, further realizing labor-saving door opening. Moreover, this setting does not require the addition of additional air pressure balancing components and does not affect the seal between the door body 2 and the box body 1, so it is low in cost and easy to implement.
[0041] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
