[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0051] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0052] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0053] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0054] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0055] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0056] refer to Figure 1-Figure 3 The present application proposes a refrigeration device, specifically a refrigerator, which includes a box body 100, a box frame 300 and a door body 200. The box body 100 includes a box body shell 110 and a box body 120. The box body 120 has a receiving cavity with an opening facing upward.

[0057] The opening of the accommodating inner cavity serves as an introduction port for placing the object to be refrigerated into the accommodating inner cavity, or for taking the refrigerated object out of the accommodating inner cavity.

[0058] The box frame 300 is arranged on the surrounding side of the opening position of the accommodating inner cavity. Specifically, the box frame 300 is connected to the box shell 110 and the box liner 120. An insulating inner cavity is formed between the box frame 300 and the box shell 110 and the box liner 120. An insulating layer is formed in the insulating inner cavity to improve the refrigeration effect of the refrigeration equipment and reduce the loss of cold.

[0059] The rear side of the door body 200 is connected to the box body 100 in a hinged manner to open or close the accommodating inner cavity.

[0060] The door body 200 includes a door body outer shell 210 and a door body inner shell 220 , and a sealed inner cavity is also formed between the door body outer shell 210 and the door body inner shell 220 .

[0061] refer to Figure 4 , Figure 5 In the prior art, a sealing strip 225 is formed on the lower surface of the door body 200. When the door body 200 is closed, the sealing strip 225 is connected to the box frame 300 to improve the sealing between the box frame 300 and the door body 200.

[0062] The sealing strip 225 is mostly fixed to the bottom of the door body 200 by bonding, and the stability and sealing of the connection are poor, so the sealing effect is poor.

[0063] Furthermore, in order to improve the sealing effect, a flow blocking portion 2201 extending toward the accommodating inner cavity is formed on the lower surface of the door body inner liner 220 in the prior art.

[0064] During actual operation, when external air enters the accommodating inner cavity through the sealing strip 225 , it is easy to be blocked at the baffle 2201 , and natural convection is slowed down. When the humidity in the air is high, frost climbing may occur at the baffle 2201 .

[0065] refer to Figure 6-Figure 9 In order to solve the above problems existing in the prior art, the present application designs a sealing surface 310 and a reinforcement surface 320 to be formed on the upper surface of the box frame 300, and the sealing surface 310 and the reinforcement surface 320 are arranged horizontally.

[0066] The reinforcement surface 320 is formed on the inner side of the sealing surface 310 , and the height of the reinforcement surface 320 is lower than that of the sealing surface 310 .

[0067] That is, the upper surface of the box frame 300 is formed in a stepped shape with a decreasing height from the outer side to the inner side.

[0068] A transition surface 330 is formed between the reinforcement surface 320 and the sealing surface 310 , and the transition surface 330 is an inclined surface.

[0069] A blocking recess 321 extending downward is formed on the reinforcement surface 320 . The blocking recess 321 may be formed integrally with the reinforcement surface 320 , or may be connected to the reinforcement surface 320 by assembly.

[0070] For example, refer to Fig.12 A long strip-shaped mounting hole is formed on the reinforcement surface 320, and the blocking recess 321 is assembled and connected to the mounting hole.

[0071] The reinforcement surface 320 is formed at least on the left and right sides of the box frame 300 , and the reinforcement surface 320 may also be provided on the surrounding side of the box frame 300 to improve the sealing effect.

[0072] The bottom surface of the door body 200 is formed with a blocking protrusion 222 extending toward the reinforcing surface 320 . Specifically, a blocking recess 321 is formed on the lower surface of the inner liner 220 of the door body.

[0073] The blocking protrusion 222 corresponds to the blocking recess 321 . When the door body 200 is in a closed state, the blocking protrusion 222 is inserted into the blocking recess 321 .

[0074] The connection between the blocking recess 321 and the blocking protrusion 222 can extend the path for the cold energy to be transmitted from the accommodating inner cavity to the outside, reduce cold air leakage, and ensure the refrigeration effect.

[0075] In addition to being sealed by the sealing strip 225, the door body 200 and the box frame 300 are also provided with a second layer of partition on the inner side of the sealing strip 225. The connection stability between the barrier protrusion 222 and the barrier recess 321 is stronger and less prone to deformation and damage. In addition to improving the sealing of the connection between the door body 200 and the box frame, it is also beneficial to prolong the path and time of the cold air in the inner cavity during natural convection to the outside world, thereby improving the cooling performance and reducing energy consumption.

[0076] In some embodiments, the sinking depth of the barrier recess 321 is 5-9 mm, and correspondingly, the outer convex dimension of the barrier protrusion 222 is not greater than the dimension of the barrier protrusion 222 .

[0077] refer to Fig.11 The lower surface of the door body inner liner 220 is formed with a matching surface corresponding to the position of the sealing surface 310 and a butt joint surface corresponding to the position of the reinforcement surface 320, and the matching surface and the butt joint surface are both arranged in parallel.

[0078] The height of the butt joint surface is lower than the mating surface, and an inclined connecting surface 224 is formed between the mating surface and the butt joint surface.

[0079] A sealing strip 225 is formed on the mating surface. In the closed state, the sealing strip 225 seals the gap between the mating surface and the sealing surface 310 .

[0080] Specifically, the sealing surface 310 is formed on the peripheral side of the box frame 300, and a sealing strip 225 is installed at the bottom of the door body 200. When the door body 200 is closed, the sealing strip 225 contacts and connects to the sealing surface 310, completely sealing the peripheral side of the door body 200 to reduce the amount of cold transported outward.

[0081] The blocking protrusion 222 is formed on the butting surface, and the blocking protrusion 222 and the inner shell of the door body 200 are an integrally formed structure.

[0082] In some embodiments of the present application, a cover portion 223 is formed in the middle of the door body inner liner 220 , and the height of the cover portion 223 is higher than the lowest position of the barrier protrusion 222 .

[0083] That is, the bottom surface of the sealing portion 223 in contact with the accommodating cavity is higher than the lowest position of the blocking protrusion 222 .

[0084] Then, a gap is formed at the position where the cover part 223 and the box frame 300 cooperate, which effectively increases the natural convection of air. The external air enters the containing cavity through the sealing strip 225. There is no obstruction around the cover part 223, and the air flows smoothly, preventing frost from forming at the position of the box frame 300 near the containing cavity.

[0085] In some other embodiments of the present application, an auxiliary sealing portion 2252 is further provided on the barrier protrusion 222 to improve the sealing between the door body 200 and the box frame 300 .

[0086] The auxiliary sealing portion 2252 may specifically be a sealing sleeve structure, which is sleeved on the outer surface of the barrier protrusion 222 , or the auxiliary sealing portion 2252 may also be provided on any outer surface of the barrier protrusion 222 .

[0087] refer to Figure 9-10 In some embodiments of the present application, a mounting groove 221 opening toward the sealing surface 310 is formed on the peripheral side of the door body inner liner 220, and a mounting throat 2211 is formed at the opening position of the mounting groove 221, and the size of the mounting throat 2211 is smaller than the mounting groove 221.

[0088] Specifically, the mounting groove portion 221 forms a groove structure extending upward on the mating surface.

[0089] The sealing strip 225 is made of rubber material and includes a mounting portion 2251 and a sealing portion 2252 . The mounting portion 2251 and the sealing portion 2252 are integrally formed.

[0090] A buckle portion that gradually shrinks in a direction away from the sealing portion 2252 is formed on the mounting portion 2251 . The mounting portion 2251 is buckled onto the mounting throat portion 2211 via the buckle portion. The sealing portion 2252 is located outside the mounting groove portion 221 .

[0091] The buckle portion includes a clamping strip formed on both sides of the mounting portion 2251. During installation, the clamping strip shrinks inwardly under the action of the mounting throat 2211. After the installation is completed, the lower end of the clamping strip is clamped on the upper side of the mounting throat 2211, and then the mounting portion 2251 is completely connected in the mounting groove 221.

[0092] The above-mentioned installation method of the sealing strip 225 can improve the installation efficiency and facilitate assembly and disassembly. After the sealing strip 225 is aged and damaged, it is convenient to disassemble and replace it.

[0093] In other embodiments, the inner side and outer side of the box frame 300 are further provided with an inner connecting portion 340 and an outer connecting portion 350 respectively. The inner connecting portion 340 and the outer connecting portion 350 are connecting outer edge structures formed on the inner and outer sides of the box frame 300 and extending downward.

[0094] The external connection portion 350 is used to connect to the box shell 110 , and the internal connection portion 340 is used to connect to the box body 120 .

[0095] During installation, the external connection part 350 is covered on the outside of the box shell 110 , and the internal connection part 340 is connected to the box body 120 .

[0096] refer to Fig.11 In some embodiments of the present application, a plug-in slot 351 opening downward is formed on the inner connection portion 340 , and the upper edge of the box body 120 is plugged into the plug-in slot 351 .

[0097] On the other hand, the present application also proposes a refrigeration device, which includes a box body 100 , a box frame 300 and a door body 200 .

[0098] The box body 100 includes a box body shell 110 and a box body liner 120 , and a receiving inner cavity with an opening facing upward is formed in the box body liner 120 .

[0099] The box frame 300 is arranged around the opening of the accommodating inner cavity, and the box frame 300 is connected to the box shell 110 and the box liner 120. The box frame 300 is formed with a sealing surface 310 and a reinforcement surface 320, and the reinforcement surface 320 is formed on the inner side of the sealing surface 310, and the height of the reinforcement surface 320 is lower than the sealing surface 310.

[0100] The rear side of the door body 200 is connected to the box body 100 by a hinged manner, and the door body 200 and the box frame are configured as follows: when the door body 200 is closed, the door body 200 and the reinforced surface 320 are embedded to increase the sealing between the door body 200 and the box frame 300.

[0101] A sealing strip 225 is provided on the sealing surface 310 . The sealing strip 225 is made of rubber material and is used to achieve a first layer of sealing between the door body 200 and the box frame 300 .

[0102] The door body 200 and the reinforcement surface 320 are arranged to be embedded, and the embedded matching box forms a second layer of sealing between the door body 200 and the box frame 300.

[0103] The double-layer sealing structure is beneficial to enhancing the sealing effect between the door body 200 and the box frame 300, reducing cold leakage, improving the refrigeration effect, and reducing energy consumption.

[0104] The specific implementation of the embedded cooperation between the door body 200 and the reinforcement surface 320 can be achieved in the following ways:

[0105] Method 1:

[0106] A blocking recess 321 is formed on the lower surface of the door body 200. Specifically, the door body 200 includes a door body outer shell 210 and a door body inner shell 220. The blocking recess 321 is a groove structure formed on the door body inner shell 220 and extending upward.

[0107] The blocking recess 321 is formed at least on two sides of the door body 200 , or the blocking recess 321 can be formed on all sides of the door body 200 .

[0108] Correspondingly, a blocking protrusion 222 adapted to the position of the blocking recess 321 is formed on the reinforced surface 320 of the box frame 300. The blocking protrusion 222 can be integrally formed on the reinforced surface 320 of the box frame 300, and can also be fixed to the surface of the reinforced surface 320 by mechanical connection later.

[0109] When the door body 200 is in a closed state, the barrier protrusion 222 is connected to the corresponding barrier recess 321 .

[0110] In other embodiments, an auxiliary sealing portion 2252 may be further provided inside the barrier recess 321 or outside the barrier protrusion 222 to further improve the sealing effect between the barrier recess 321 and the barrier protrusion 222 .

[0111] Method 2:

[0112] refer to Fig.11 In the present application, a sealing surface 310 and a reinforcement surface 320 are formed on the upper surface of the box frame 300, and the sealing surface 310 and the reinforcement surface 320 are arranged horizontally.

[0113] The reinforcement surface 320 is formed on the inner side of the sealing surface 310 , and the height of the reinforcement surface 320 is lower than that of the sealing surface 310 .

[0114] A transition surface 330 is formed between the reinforcement surface 320 and the sealing surface 310 , and the transition surface 330 is an inclined surface.

[0115] Compared with the previous method, the blocking recess 321 in the second method is formed on the reinforcement surface 320. The blocking recess 321 can be formed integrally with the reinforcement surface 320, or can be connected to the reinforcement surface 320 by assembly.

[0117] In addition to being sealed by the sealing strip 225, the door body 200 and the box frame 300 are also provided with a second layer of partition on the inner side of the sealing strip 225. The connection stability between the barrier protrusion 222 and the barrier recess 321 is stronger and less prone to deformation and damage. In addition to improving the sealing of the connection between the door body 200 and the box frame, it is also beneficial to prolong the path and time of the cold air in the inner cavity during natural convection to the outside world, thereby improving the cooling performance and reducing energy consumption.

[0118] Method 3:

[0119] In some embodiments of the present application, a cover portion 223 is formed in the middle of the door body inner liner 220 , and the height of the cover portion 223 is higher than the lowest position of the barrier protrusion 222 .

[0120] That is, the bottom surface of the sealing portion 223 in contact with the accommodating cavity is higher than the lowest position of the blocking protrusion 222 .

[0121] Then, a gap is formed at the position where the cover part 223 and the box frame 300 cooperate, which effectively increases the natural convection of air. The external air enters the containing cavity through the sealing strip 225. There is no obstruction around the cover part 223, and the air flows smoothly, preventing frost from forming at the position of the box frame 300 near the containing cavity.

[0122] The gap between the cover portion 223 and the box frame 300 can increase the natural convection of the top air, and effectively prevent the frosting problem caused by poor air circulation at the box frame 300.

[0123] After the external air enters the containing cavity, natural air convection and cooling are performed at the top of the containing cavity to prevent frost from forming at the position of the box frame 300 near the containing cavity.

[0124] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0125] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
