[0054] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0055] The refrigeration device in the present application generally includes a cabinet, a door body, and a refrigeration system. Among them, at least one refrigeration compartment is formed in the cabinet, and the refrigeration compartment is opened and closed through the door body to meet the requirements of accessing items.

[0056] Among them, the refrigeration system performs the refrigeration cycle of the refrigeration device by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to achieve refrigeration of the items in the cabinet.

[0057] The low-temperature and low-pressure refrigerant enters the compressor, and the compressor compresses it into a refrigerant gas in a high-temperature and high-pressure state 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.

[0058] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can refrigerate the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0059] Reference Figures 1-4 , this application proposes a refrigeration device, specifically a freezer, which includes a box body 100, a box frame 300, and a door body 200. The box body 100 includes an outer shell 110 and an inner liner 120, and a refrigeration cavity 101 with an upward opening is formed in the inner liner 120.

[0060] The opening of the refrigeration cavity 101 serves as an introduction port for placing items to be refrigerated into the refrigeration cavity 101 or taking out the refrigerated items from the refrigeration cavity 101.

[0061] The box frame 300 is arranged on the periphery of the opening position of the refrigeration cavity 101. Specifically, the box frame 300 is respectively connected to the outer shell 110 and the inner liner 120, and a heat insulation cavity is formed between the box frame 300 and the outer shell 110 and the inner liner 120. A heat insulation layer is formed in the heat insulation cavity to reduce the loss of cold quantity and improve the refrigeration effect of the refrigeration device.

[0062] The rear side of the door body 200 is connected to the box body 100 in a hinged manner for opening or closing the refrigeration cavity 101.

[0063] The door body 200 includes a door body outer shell and a door body inner liner, and a heat insulation cavity is also formed between the door body outer shell and the door body inner liner. A heat insulation layer is formed in the heat insulation cavity to reduce the outward transfer of cold quantity from the door body 200.

[0064] In order to reduce the outward transfer of cold quantity in the refrigeration cavity 101, this application is provided with door seals on both the door body 200 and the box frame 300. The door seals on the door body 200 and the box frame 300 are in interference connection with each other when the door body 200 is in the closed state, sealing the gap between the door body 200 and the box frame 300.

[0065] Specifically, reference Figures 5-9 , a first sealing surface 201 for contact connection with the box frame 300 is formed on the door body 200, a first door seal 210 is arranged on the first sealing surface 201, a second sealing surface 301 adapted to the first sealing surface 201 is formed on the box frame 300, and a second door seal 310 is arranged on the second sealing surface 301.

[0066] The first sealing surface 201 is formed at least on at least one circumferential side surface of the door body 200 close to the box frame 300, and the second sealing surface 301 corresponds to the first sealing surface 201 and is formed at least on at least one circumferential side surface of the box frame 300.

[0067] In some embodiments of the present application, in order to improve the sealing effect, the first sealing surface 201 is formed on the circumferential side of the door body 200, and the second sealing surface 301 is also formed on the circumferential side of the box frame 300 to seal the four sides of the refrigeration cavity 101.

[0068] The first door seal 210 and the second door seal 310 are provided with at least two layers of seals along the direction close to the refrigeration cavity 101.

[0069] In some embodiments of the present application, specifically referring to Figure 7 , the first door seal 210 includes a first contact portion 211 and a first adsorption portion 212, and the second door seal 310 includes a second contact portion 311 and a second adsorption portion 312; the first contact portion 211 is connected to the first sealing surface 201, and the first adsorption portion 212 is located inside the first contact portion 211; the second contact portion is connected to the second sealing surface 301, and the second adsorption portion 312 is located inside the second contact portion 311.

[0070] In other words, when the door body 200 is closed, the first contact portion 211 and the second contact portion 311 on the first door seal 210 and the second door seal 310 are squeezed and sealed to form the first layer of seal, and the first adsorption portion 212 and the second adsorption portion 312 located inside are adsorbed and connected together to form the second layer of seal.

[0071] In some embodiments of the present application, the materials of the first door seal 210 and the second door seal 310 are both rubber, the first contact portion 211 and the first adsorption portion 212 are integrally formed, and the second contact portion 311 and the second adsorption portion 312 are integrally formed.

[0072] In the closed state of the door body 200, a gap is formed between the first sealing surface 201 of the door body 200 and the second sealing surface 301 of the box frame 300 under the action of the first contact portion 211 and the second contact portion 311, and the first adsorption portion 212 and the second adsorption portion 312 are adsorbed and connected in the gap.

[0073] Referring to Figure 10 、 Figure 11 , in some embodiments of the present application, installation cavities are formed in the first adsorption portion 212 and the second adsorption portion 312, and magnetic attraction portions are respectively arranged in the installation cavities. When the door body 200 is in the closed state, the first adsorption portion 212 and the second adsorption portion 312 are adsorbed and connected together under the action of the magnetic attraction portions.

[0074] Specifically, the first adsorption portion 212 and the second adsorption portion 312 are respectively provided with strip-shaped first installation cavities 2121 and second installation cavities 3121 along their extending directions, and strip-shaped magnetic adsorption portions are respectively arranged in the first installation cavity 2121 and the second installation cavity 3121.

[0075] When the door body 200 is closed, the first adsorption portion 212 and the second adsorption portion 312 gradually approach each other. Under the adsorption action of the magnetic adsorption portion, the first adsorption portion 212 and the second adsorption portion 312 are connected. When the door body 200 is opened and closed, under the action of an external force, the first adsorption portion 212 and the second adsorption portion 312 are separated.

[0076] Combined Figure 7 , in some embodiments of the present application, first card slot portions 202 and second card slot portions 302 with opposite openings are respectively formed on the first sealing surface 201 and the second sealing surface 301. Corresponding first clamping portions 213 and second clamping portions 313 are arranged on the first door seal 210 and the second door seal 310. The first clamping portion 213 is in clamping fit with the first card slot portion 202, and the second clamping portion 313 is in clamping fit with the second card slot portion 302 to realize the detachable connection between the first door seal 210 and the door body 200, and between the second door seal 310 and the box frame 300.

[0077] The first clamping portion 213 and the second clamping portion 313 respectively include an intermediate portion and a clamping end portion, and the intermediate portion is located between the clamping end portion and the first contact portion 211 or the second contact portion 311.

[0078] That is, the first clamping portion 213 includes a first intermediate portion 2131 and a first clamping end portion 2132, and the second clamping portion 313 includes a second intermediate portion 3131 and a second clamping end portion 3132. The first intermediate portion 2131, the first clamping end portion 2132 and the first contact portion 211 are integrally formed, and the second intermediate portion 3131, the second clamping end portion 3132 and the second contact portion 311 are integrally formed.

[0079] In some embodiments of the present application, installation throats are formed on the first card slot portion 202 and the second card slot portion 302. The size of the installation throat is smaller than that of the first card slot portion 202 and the second card slot portion 302. The first clamping portion 213 and the second clamping portion 313 are respectively connected to the first card slot portion 202 and the second card slot portion 302 through the corresponding installation throats.

[0080] The clamping end portion tapers in a direction away from the intermediate portion, and a limiting wing portion is formed at one end of the clamping end portion close to the intermediate portion. The clamping end portion is connected in the first card slot portion 202 or the second card slot portion 302 through the installation throat, and the limiting wing portion is located inside the installation throat.

[0081] Specifically, the first limiting wing parts formed on both sides of the first clamping end part 2132 are clamped to the inner side of the installation throat part corresponding to the first clamping groove part 202, so as to connect and fix the first clamping part 213.

[0082] The second limiting wing parts formed on both sides of the second clamping end part 3132 are clamped to the inner side of the installation throat part corresponding to the second clamping groove part 302, so as to connect and fix the second clamping part 313.

[0083] The first door seal 210 and the second door seal 310 are made of rubber material as a whole, and they have a certain elasticity. Taking the first door seal 210 as an example: during installation, the first clamping end part 2132 moves through the installation throat part into the first clamping groove part 202. The first limiting wing parts on both sides are compressed towards the middle under the action of the installation throat part until the first clamping end part 2132 completely passes through the installation throat part. Then, the first limiting wing parts on both sides expand and reset outward, and are clamped to the inner side of the installation throat part, realizing the installation of the first door seal 210.

[0084] For the refrigeration equipment involved in this application, a first door seal 210 and a second door seal 310 are respectively arranged on the door body 200 and the box frame 300. When the door body 200 is in the closed state, an effective closure is formed between the first door seal 210 and the second door seal 310, avoiding the influence caused by the deformation of a single door seal, and the sealing effect is better.

[0085] In addition, referring again to Figure 7 , the first door seal 210 and the second door seal 310 are provided with at least two layers of seals along the direction close to the refrigeration inner cavity 101, effectively reducing the loss of cold quantity in the refrigeration inner cavity 101, improving the refrigeration effect, and reducing energy consumption.

[0086] In some embodiments of this application, a sealing tail wing is further formed on the clamping end part. The sealing tail wing is integrally formed with the first door seal 210 or the second door seal 310, and the sealing tail wing is compressed into the first clamping groove part 202 or the second clamping groove part 302.

[0087] After the first clamping part 213 and the second clamping part 313 are connected to the first clamping groove part 202 and the second clamping groove part 302, the first sealing tail wing 214 formed on the first clamping part 213 is connected to the corresponding first clamping groove part 202, and the second sealing tail wing 314 formed on the second clamping part 313 is connected to the corresponding second clamping groove part 302.

[0088] The sealing tail wing can increase the sealing performance between the first clamping part 213 and the first clamping groove part 202, and between the second clamping part 313 and the second clamping groove part 302, and reduce the loss of cold quantity between the first clamping part 213 and the first clamping groove part 202, and between the second clamping part 313 and the second clamping groove part 302.

[0089] In some embodiments of the present application, a first extension portion 215 bent toward the first sealing surface 201 is formed on the first contact portion 211, and the first extension portion 215 and the first adsorption portion 212 are respectively located on the inner and outer sides of the first contact portion 211.

[0090] That is, the first extension portion 215 is located on the side of the first contact portion 211 away from the refrigeration cavity 101, and the end of the first extension portion 215 contacts the first sealing surface 201, or is inserted into the connection groove formed on the first sealing surface 201, so as to further improve the sealing performance of the connection between the first sealing surface 201 and the first contact portion 211.

[0091] Similarly, a second extension portion 315 bent toward the second sealing surface 301 is formed on the second contact portion 311, and the second extension portion 315 and the second adsorption portion 312 are respectively located on the inner and outer sides of the second contact portion 311.

[0092] The second extension portion 315 is located on the side of the second contact portion 311 away from the refrigeration cavity 101, and the end of the second extension portion 315 contacts the second sealing surface 301, or is inserted into the connection groove formed on the second sealing surface 301, so as to further improve the sealing performance of the connection between the second sealing surface 301 and the second contact portion 311.

[0093] In some other embodiments of the present application, the box frame 300 further includes an outer connection portion 320 and an inner connection portion 330. The outer connection portion 320 is used to connect with the outer shell 110, and the inner connection portion 330 is used to connect with the inner container 120.

[0094] The inner connection portion 330 and the outer connection portion 320 are respectively connection outer edge structures formed on the inner and outer sides of the box frame 300 and extending downward.

[0095] During installation, the outer connection portion 320 covers the outside of the outer shell 110, and the inner connection portion 330 is connected with the inner container 120.

[0096] In some embodiments of the present application, in order to improve the connection stability between the box frame 300 and the outer shell 110 and the inner container 120, plugging slots with openings facing downward are formed on the outer connection portion 320 and / or the inner connection portion 330, and the upper edges of the outer shell 110 and / or the inner container 120 are plugged into the corresponding plugging slots.

[0097] This refrigeration device refrigerates the refrigeration cavity 101 through a refrigeration system. The refrigeration system includes a compressor, a condenser, and an evaporator, and the compressor, the condenser, and the evaporator are connected through refrigeration pipelines.

[0100] On the other hand, the present application also proposes a refrigeration device, which includes a box body 100, a door body 200 and a box frame 300.
