[0069] The refrigeration equipment in this application typically includes a cabinet, a door, and a refrigeration system. The cabinet contains at least one refrigeration compartment, which is opened and closed via a door to meet the requirements for storing and retrieving items.

[0070] The refrigeration system executes a refrigeration cycle using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle comprises a series of processes involving compression, condensation, expansion, and evaporation to cool the items inside the container.

[0071] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, 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.

[0072] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator can cool the items inside the container by utilizing the latent heat of refrigerant evaporation.

[0073] This application proposes a refrigeration device, which includes a cabinet and a door. A refrigeration chamber is formed inside the cabinet. The refrigeration chamber specifically includes a refrigerator compartment and a freezer compartment. Food inlet ports are formed at the front ends of both the refrigerator compartment and the freezer compartment. The refrigerator compartment is used to preserve food, and the freezer compartment is used to freeze food.

[0074] The door is attached to the cabinet and is used to control the switch of the food inlet port. It can be used to switch the refrigerator compartment or the freezer compartment on and off.

[0075] refer to Figures 1-3 The door body includes a door shell 100, a door inner liner 200, a support assembly, and an end cap assembly 400. The support assembly and the end cap assembly 400 are disposed between the door shell 100 and the door inner liner 200.

[0076] The inner door liner 200 is located on the side of the outer door shell 100 near the cooling chamber, and the support assembly includes two support members 300 arranged opposite each other.

[0077] Two support members 300 are respectively located on the left and right sides of the door shell 100 and the door inner liner 200. Each support member 300 is vertically arranged to provide support for the door body.

[0078] The end cap assembly 400 includes two end caps respectively disposed at both ends of the support member 300. The two end caps are horizontally disposed at the upper and lower ends of the door body, and one of the end caps has a handle portion 411 recessed towards the cooling chamber.

[0079] An insulated inner cavity is formed between the door inner liner 200, the door outer shell 100, the end cap assembly 400, and the support assembly.

[0080] The door inner liner 200 specifically includes an inclined portion 210 and a vertical portion 220. The inclined portion 210 is located at one end near the handle portion 411 and is inclined away from the door outer shell 100.

[0081] An insulation element is provided on the inner side of the inclined part 210. The inclined part 210 and the insulation element are used to prevent the cold air in the refrigeration chamber from being transmitted to the handle part 411.

[0082] Insulation components are also provided in the insulation cavity corresponding to the vertical part 220. The insulation component provided on the inside of the inclined part is defined as the first insulation component 110, and the insulation component corresponding to the vertical part is the second insulation component 120. The first insulation component 110 is attached to the inner wall of the inclined part 210.

[0083] The inclined portion 210 and the vertical portion 220 on the inner door liner 200 are integrally formed sheet metal structures, with the inclined portion 210 specifically formed by bending the vertical portion 220.

[0084] refer to Figure 3 The end cap assembly 400 includes a first end cap 410 and a second end cap 420, which are respectively disposed at the upper and lower ends of the door body.

[0085] In some embodiments, a handle portion 411 is formed on the first end cap 410, that is, the handle portion 411 is disposed on the top of the door body, and correspondingly, the inclined portion 210 is located on the top of the door inner liner 200.

[0086] When the handle 411 is located at the top of the door, the inclined portion 210 gradually tilts from bottom to top in a direction away from the door shell 100 to increase the thickness of the heat-insulating inner cavity corresponding to the handle 411 and reduce the transfer of cold energy.

[0087] In some other embodiments, the handle portion 411 is formed on the second end cover 420, that is, the handle portion 411 is provided at the bottom of the door body, and the user pushes or pulls the handle portion 411 from the bottom of the door body to open or close the door body.

[0088] Correspondingly, the inclined portion 210 is also formed at the bottom of the vertical portion 220. The inclined portion 210 gradually inclines away from the door housing 100 from top to bottom to increase the thickness of the heat preservation inner cavity corresponding to the handle portion 411 and reduce the cold quantity transfer.

[0089] The inclined portion 210 provided on the inner door liner 200 can increase the thickness of the heat preservation inner cavity corresponding to the inside of the handle portion 411. An insulating member is attached to the inside of the inclined portion 210. Under the combined action of the thickened heat preservation inner cavity and the insulating member, the cold quantity in the refrigerating inner cavity is better insulated, which is beneficial to avoiding the problem of condensation on the handle portion 411.

[0090] In addition, the inclined portion 210 does not occupy too much space in the refrigerating inner cavity, which can ensure the storage space in the refrigerating inner cavity and the volume utilization rate of the refrigerating inner cavity.

[0091] Reference Figures 4-9 In some embodiments of the present application, a rounded corner 412 is formed at the bottom of the handle portion 411, which improves the comfort of the user's hand holding and can avoid sanitary dead corners and facilitate cleaning.

[0092] The radius range of the rounded corner 412 is 7mm < R < 8mm. For example but not limited to, the radius R of the rounded corner 412 at the bottom of the handle portion 411 is 7.5mm.

[0093] In some other embodiments, the size range of the minimum distance L between the outer wall of the rounded corner 412 and the insulating member is 26mm to 28mm. For example but not limited to, the minimum distance between the outer wall of the rounded corner 412 and the insulating member is 27mm.

[0094] In some embodiments of the present application, the thickness d of the insulating member ranges from 9mm to 11mm to meet the heat insulation requirements of the door body. For example but not limited to, the thickness of the insulating member is 10mm.

[0095] In some embodiments of the present application, the range of the angle θ between the plane where the inclined portion 210 is located and the plane where the vertical portion 220 is located is 162 degrees to 166 degrees. For example but not limited to, the angle between the inclined portion 210 and the vertical portion 220 is 164 degrees.

[0096] The insulation material is VIP vacuum insulation material, whose insulation performance is equivalent to three times the thickness of a traditional foam layer. Under the conditions of the tilt range of the tilted part 210, the thickness of the insulation material, and the distance between the outer wall of the rounded corner 412 and the insulation material, the effective foam layer thickness of the heat-insulating inner cavity corresponding to the handle part 411 is approximately D=L+d=27+10*3=57mm, which meets the minimum foam layer thickness of the ultra-thin door body.

[0097] In some embodiments of this application, the projection height of the inclined portion 210 on the plane where the vertical portion 220 is located ranges from 84mm to 86mm, in order to meet the heat insulation requirements of the handle portion 411.

[0098] In some embodiments of this application, an outer plate 430 is detachably connected to the outer side of the first end cap 410, and the outer plate 430 extends to the outer side of the handle portion 411 to facilitate the user's hand-held push and pull.

[0099] The outer panel 430 and the first end cover 410 are processed separately and then assembled, which helps to improve processing efficiency.

[0100] Combination Figure 8 , Figure 9 In some embodiments of this application, the top of the outer panel 430 is formed with an outwardly extending limiting portion 431, and the top of the door shell 100 is in contact with the limiting portion 431.

[0101] The limiting part 431 is used to cover the gap between the door shell 100 and the outer panel 430, and facilitates the positioning of the door shell 100.

[0102] In some embodiments of this application, a smooth surface is formed on the limiting portion 431 to improve the comfort of the user's hand and provide a better experience when the user holds it.

[0103] refer to Figures 10-12 Taking the example where the handle 411 is located on the first end cover 410 of the door body:

[0104] The first end cap 410 has a fixed surface 413 on one side where the handle portion 411 is formed. The outer upright plate 430 is connected to the fixed surface 413. The fixed surface 413 has a positioning protrusion, and the outer upright plate 430 has a positioning hole. During installation, the outer upright plate 430 is initially positioned through the positioning hole and the positioning protrusion.

[0105] Multiple fixing holes 414 are also provided at intervals on the fixing surface 413, and corresponding through holes are provided on the outer panel 430. Fasteners such as fastening screws pass through the through holes and are fixedly connected in the fixing holes 414 to fix the outer panel 430.

[0106] The support assembly includes support members 300 disposed on both sides of the door body. Each support member 300 includes a support upright 310, an inner bending part 320, and an outer bending part 330.

[0107] The inner bend 320 and the outer bend 330 are formed on both sides of the support stand 310 and extend to the same side of the support stand 310. The upper and lower ends of the support member 300 are respectively connected to the first end cover 410 and the second end cover 420. The door shell 100 is connected to the outer bend 330, and the door liner 200 is connected to the inner bend 320.

[0108] The support upright 310, the inner bending part 320, and the outer bending part 330 are integrally formed. The support upright 310 forms two sides of the door body. The inner bending part 320 and the outer bending part 330 are respectively used to connect with the inner door liner 200 and the outer door shell 100 to make the connection more stable and the installation easier.

[0109] The top of the support stand 310 also has an upwardly extending overlapping part. The overlapping part is arc-shaped and is used to overlap the first end cover 410. The outer surface of the overlapping part is smooth so that the connection between the support stand 310 and the first end cover 410 is smoother and more comfortable, improving the user experience.

[0110] The end cap assembly 400 is fixed to the support assembly by a snap-fit ​​connection.

[0111] In some embodiments of this application, the first end cap 410 has a first mating portion extending between the inner bend 320 and the outer bend 330 at both ends, and the first end cap 410 is connected to the support members 300 at both ends through the first mating portion.

[0112] The first mating part has an inner connecting surface that contacts the inner bending part 320 and an outer connecting surface that contacts the outer bending part 330. Both the inner connecting surface and the outer connecting surface have a snap-fit ​​protrusion 401.

[0113] The inner bend 320 and the outer bend 330 are formed with snap-fit ​​portions 301, and the snap-fit ​​protrusion 401 is snap-fitted to the corresponding snap-fit ​​portion 301 to realize the detachable connection between the first end cap 410 and the support member 300.

[0114] Specifically, the snap-fit ​​portions 301 on the support member 300 snap-fit ​​from the outside of the first end cover 410 to the snap-fit ​​protrusion 401. The snap-fit ​​portions 301 are specifically snap-fit ​​interfaces formed on the inner bend portion 320 and the outer bend portion 330.

[0115] The height of the buckle protrusion 401 protrudes from the inner and outer connecting surfaces, gradually increasing from the outside to the inside.

[0116] In other words, along the installation direction of the support member 300, the height of the snap-fit ​​protrusion 401 gradually increases, and the support member 300 expands outward under the total force of the snap-fit ​​protrusion 401 until the snap-fit ​​protrusion 401 connects to the snap-fit ​​portion 301, and the support member 300 returns to its original position.

[0117] In some embodiments of this application, a second mating portion is formed on the second end cap 420, extending between the inner bend portion 320 and the outer bend portion 330.

[0118] The second mating part has an inner connecting surface that contacts the inner bending part 320 and an outer connecting surface that contacts the outer bending part 330.

[0119] Both the inner and outer connecting surfaces have snap-fit ​​protrusions 401, and the inner bending portion 320 and the outer bending portion 330 have snap-fit ​​portions 301. The snap-fit ​​protrusions 401 are snap-fitted to the corresponding snap-fit ​​portions 301 to achieve a detachable connection between the second end cap 420 and the support member 300.

[0120] Similar to the connection method of the support member 300 and the first end cover 410, specifically, the snap-fit ​​portion 301 on the support member 300 snaps onto the snap-fit ​​protrusion 401 from the outside of the second end cover 420. Specifically, the snap-fit ​​portion 301 is a snap-fit ​​interface formed on the inner bend portion 320 and the outer bend portion 330.

[0121] The height of the buckle protrusion 401 protrudes from the inner and outer connecting surfaces, gradually increasing from the outside to the inside.

[0122] In other words, along the installation direction of the support member 300, the height of the snap-fit ​​protrusion 401 on the second end cover 420 gradually increases, and the support member 300 expands outward under the total force of the snap-fit ​​protrusion 401 until the snap-fit ​​protrusion 401 connects to the snap-fit ​​portion 301, and the support member 300 returns to its original position.

[0123] Both the first end cap 410 and the second end cap 420 are connected to the support member 300 by snap-fit, which makes assembly easier and more efficient.

[0124] refer to Figure 9 In some embodiments of this application, the door liner 200 has a mounting recess with an opening facing the cooling chamber. The mounting recess is continuously disposed on the periphery of the door liner 200, and the door seal 500 is fixed to the door liner 200 through the mounting recess.

[0125] The door seal 500 is provided with a plug-in part, which is inserted into the mounting recess to achieve a detachable connection between the door seal 500 and the door inner liner 200.

[0126] The opening of the mounting recess has a connecting throat smaller than the mounting recess. The end of the plug has a plug tip, and sealing wings extending to both sides of the plug tip are also formed. During installation, the plug is inserted into the mounting recess through the connecting throat. The sealing wings are also located inside the connecting throat. In addition to ensuring the 500 sealing strength of the door seal, it also has a positioning effect to prevent the plug from coming out of the mounting recess.
