[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0059] The door body 200 is hinged on the box body 100 and is used to open or close the refrigeration cavity.

[0060] The refrigeration device of the present application is specifically a beverage cabinet, which can be used not only to store beverages but also to refrigerate some foods and even medicines.

[0061] The door 200 of the beverage cabinet is a transparent structure, which is convenient for users to observe the beverages, medicines or food in the refrigeration cavity.

[0062] A supporting layer frame is arranged in the refrigeration inner cavity of the refrigeration equipment for stratifying the refrigeration inner cavity.

[0063] refer to Figure 2-Figure 4 The door body 200 includes a door body frame 220 , a door body outer shell 210 and a door body inner shell 230 .

[0064] The door frame 220 serves as a main supporting structure of the door 200 , the door outer shell 210 is formed on the outer side of the door frame 220 , and the door inner shell 230 is formed on the inner side of the door frame 220 .

[0065] The door outer shell 210 and the door inner shell 230 are both made of transparent materials, such as glass.

[0066] The circumferential sides of the door outer shell 210 and the door inner shell 230 are both fixed on the door frame 220 , and an intermediate layer is formed between the door outer shell 210 and the door inner shell 230 .

[0067] A display element 280 is provided in the middle layer for displaying the customer's brand logo or other advertisements.

[0068] In order to improve the display effect, the display element 280 is configured to be connected to the power source through the conductive silver paste 281 and the power harness 270.

[0069] That is, the display element 280 is configured as a charged lamp panel structure, and the display element 280 is connected to the energized harness 270 via the conductive silver paste 281 .

[0070] The display element 280 is specifically attached to the surface of the door inner shell 230 , and the conductive silver paste 281 is also formed on the door inner shell 230 .

[0071] Compared with traditional structures such as wires or connecting columns, the conductive silver paste 281 is helpful in maintaining the integrity of the appearance of the display element 280 such as the customer logo, and the aesthetics is improved.

[0072] Furthermore, the use of the conductive silver paste 281 can reduce the number of wire holes on the door body 200, which is beneficial to improving the sealing effect inside the refrigeration equipment and reducing cold air leakage.

[0073] Specifically, the wiring harness 270 is passed from the door frame 220 to the middle interlayer. Specifically, a wire threading portion 221 is formed on the door frame 220, and the wire threading portion 221 is a through-hole structure.

[0074] The power harness 270 passes through the wire threading portion 221 and extends into the middle interlayer.

[0075] Specific reference Figure 3 , an elastic contact 282 is provided on the display element 280 , and the conductive silver paste 281 is connected to the display element 280 through the elastic contact 282 .

[0076] Specifically, the power harness 270 includes an input end and an output end, and the input end and the output end of the power harness are respectively connected to the corresponding elastic contacts 282 through conductive silver paste 281 .

The input end and the output end of the power harness 270 are respectively located on the outside of the partition bar 261 .

[0078] The input and output ends of the power harness 270 are on the outside of the partition bar 261, and do not directly pass through the partition bar 261 to connect with the display element 280. This can reduce the generation of gaps such as threading holes during the connection of the power harness 270, improve the thermal insulation performance of the door body 200, and also help reduce the entry of dust into the middle layer.

[0079] Combination Figure 5 In some embodiments of the present application, conductive silver paste 281 is formed on both sides of the display element 280, the conductive silver paste on one side is connected to the input end of the power harness 270, and the conductive silver paste 281 on the other side is connected to the output end of the power harness 270.

[0080] The input and output ends of the power harness 270 are both passed through the threading portion 221 on the door frame 220 into the middle interlayer and extend to the outside of the partition bar 261. The threading portion 221 is located on the side close to the hinge of the door body 200 to reduce the path of the power harness 270.

[0081] After the input end and the input end of the power harness 270 pass through the threading portion 221 , one end extends downward to connect with the conductive silver paste 281 on one side of the display element 280 , and the other end goes around along the outer side of the partition bar 261 to the other side of the display element 280 to connect with the conductive silver paste 281 on the other side of the display element 280 .

[0082] A sealing outer frame 260 is further provided on the outer side of the partition bar 261 , and the sealing outer frame 260 presses the input end and the output end of the power harness 270 onto the inner shell 230 of the door body respectively.

[0084] Conductive silver paste 281 has the characteristics of extremely high bonding strength and stable electrical properties, which is beneficial to improve the sealing of the middle layer, reduce cold air leakage, prevent dust from entering the middle layer, and reduce cleaning costs.

[0085] A supporting inner frame 240 is also provided on the door frame 220 , and the supporting inner frame 240 is located on the inner side of the door inner shell 230 .

[0086] A sealing portion 250 is further provided on the peripheral side of the supporting inner frame 240 . The material of the sealing portion 250 is rubber. The sealing portion 250 is used to seal the gap between the box body 100 and the door body 200 .

[0088] A cover assembly is disposed at the rear side of the compressor compartment. The cover assembly includes a rear cover body 110 disposed at the rear side of the compressor compartment and a storage member 120 detachably connected to the rear cover body 110 .

[0089] When the air duct inside the compressor compartment is of the front-to-back type, in order to improve the heat exchange efficiency and increase the air output, the present application makes the rear cover body 110 into a grid shape to reduce the obstruction to the airflow.

[0090] In some embodiments of the present application, the rear cover body 110 is a planar grille formed by staggered steel wires, and the size of the rear cover body 110 is adapted to the opening size of the compressor compartment to seal the compressor compartment.

[0091] An installation position 111 is formed on the rear cover body 110 . The installation position 111 is specifically a mounting opening structure formed on the rear cover body 110 . The storage member 120 is detachably connected to the installation position 111 .

[0096] The storage member 120 and the rear cover body 110 are manufactured separately and then assembled to improve processing efficiency and provide more comprehensive protection for the power harness 130 .

[0097] In some embodiments of the present application, limiting slots are formed on opposite sides of the receiving opening, the opening direction of the limiting slots is toward the peripheral side of the receiving opening, and the limiting slots are respectively connected to the mounting positions 111.

[0098] That is, during installation, the storage member 120 is inserted into the peripheral side of the installation opening through the limiting groove.

[0101] The upper grille portion 113 and the lower grille portion 112 are both made of steel wire. After the first limiting slot and the second limiting slot are respectively inserted into the upper grille portion 113 and the lower grille portion 112, they are further connected and fixed by fasteners such as fastening screws.

[0102] A first fastening portion is detachably connected between the first outer edge 122 and the first inner edge 1221 , and a second fastening portion is detachably connected between the second outer edge 125 and the second inner edge 1251 .

[0103] Specifically, a first fastening outer hole 1222 is formed on the first outer edge 122 , and a first fastening inner hole 1223 is formed on the first inner edge 1221 . The first fastening outer hole 1222 is a through hole structure, and the first fastening inner hole 1223 is a threaded hole.

[0104] After the upper grille portion 113 is inserted into the first limiting slot, the first fastening portion is passed through the first fastening outer hole 1222 and connected to the first fastening inner hole 1223 .
