[0002] With social development, refrigeration equipment such as refrigerators are gradually moving towards high-end, ultra-thin, and aesthetically pleasing designs to enhance the user's visual experience and improve the product's grade.

[0003] Traditional refrigerator doors often use steel plates or plastic frames. While these materials are inexpensive, easy to process, and have low manufacturing costs, they often suffer from problems such as frame deformation, glass delamination, or gaps at joints under high and low temperature conditions, causing cold air leakage and affecting the cooling effect of the refrigeration equipment. In addition, during use, traditional plastic or steel plate support frames are difficult to maintain the structural stability and aesthetics of the door, causing inconvenience for users of high-end refrigerators. Utility Model Content

[0004] The purpose of this utility model is to provide a refrigeration device to solve the problems existing in the prior art, such as the traditional refrigerator door support frame being prone to deformation, poor structural strength, poor connection stability between the support frame and the end cover, and the presence of gaps that affect the refrigeration effect of the refrigeration device.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0006] This utility model proposes a refrigeration device, which includes:

[0007] The housing contains a refrigeration chamber, and a food inlet port is formed at the front end of the refrigeration chamber.

[0008] A door, connected to the housing, for controlling the opening and closing of the food inlet port; the door includes:

[0009] Door shell;

[0010] The inner liner of the door is located on the side of the outer shell of the door near the cooling chamber;

[0011] A support assembly, connected between the door outer shell and the door inner liner, includes two support members disposed opposite to each other;

[0012] An end cap assembly, comprising two end caps disposed at both ends of the support member and disposed opposite to each other;

[0013] In this embodiment, at least one end cap has downwardly extending snap-fit ​​portions at both ends, and two corresponding positions of the two support uprights are provided with snap-fit ​​portions. The snap-fit ​​portions cooperate with the corresponding snap-fit ​​portions to achieve a detachable connection between the end cap and the support member.

[0014] In some embodiments of this application, the support member is made of aluminum alloy.

[0015] Compared to plastic support components, aluminum alloy support components have better temperature resistance and are less prone to issues such as gaps and glue separation at the connection between the door shell, door liner, and support components, as well as frame deformation.

[0016] In some embodiments of this application, the support member includes a support stand and an inner bend and an outer bend formed on both sides of the support stand and extending toward the same side of the support stand, the door shell is connected to the outer bend, and the door liner is connected to the inner bend.

[0017] The support upright, inner bending part, and outer bending part are integrally formed. The support upright forms the two sides of the door body. The inner bending part and outer bending part are used to connect with the inner door liner and the outer door shell, respectively, so as to make the connection more stable and easy to install.

[0018] In some embodiments of this application, a thermal insulation cavity is formed between the door shell, the door inner liner, the end cap assembly, and the support assembly, and a thermal insulation layer is provided in the thermal insulation cavity.

[0019] The insulation layer is used to reduce the loss of cold air in the cooling cavity and improve the cooling effect.

[0020] In some embodiments of this application, the snap-fit ​​portion is formed on the inner side of the support stand near the heat-insulating inner cavity. The snap-fit ​​portion includes a guide portion formed at one end of the end cap and extending downward, and claws formed on both sides of the guide portion. A gap is formed between the guide portion and the claws. The snap-fit ​​portion includes two opposing snap blocks, and a guide rail portion is formed between the two snap blocks. The guide portion is connected to the guide rail portion, and the claws snap onto the bottom of the corresponding snap block.

[0025] During installation, the snap-fit ​​bevel on the claw contacts the guide bevel. As the end cap is installed, the snap-fit ​​bevel gradually expands outward along the guide bevel, causing the claw to expand outward. After the snap-fit ​​bevel contacts the outer side of the snap block upright, it moves straight down until the snap-fit ​​end snaps into the bottom of the snap-fit ​​upright under its own restoring force, completing the connection between the snap-fit ​​part and the snap-fit ​​part.

[0026] In some embodiments of this application, the end cap is further provided with a connecting protrusion that connects to the inner bend and the outer bend. The inner bend and the outer bend are formed with connecting holes that are adapted to the position of the connecting protrusion, and the connecting protrusion is connected to the corresponding connecting hole.

[0027] In some embodiments of this application, an adhesive surface is formed on the outer bend, the door shell is adhered to the adhesive surface, and at least one overflow groove extending along the length direction of the support member is formed on the adhesive surface, the overflow groove being used to hold excess adhesive.

[0028] Excess adhesive overflows into the overflow groove on the bonding surface, preventing insufficient adhesive from affecting the bonding strength, or excessive adhesive from overflowing onto the outside of the door and affecting its appearance.

[0029] In some embodiments of this application, the periphery of the door liner has a mounting recess with an opening facing the cooling chamber, and the door seal is provided with a plug-in portion, which is inserted into the mounting recess to realize that the door seal is detachably connected to the door liner.

[0030] On the other hand, this application also proposes a refrigeration device, which includes:

[0031] The housing contains a refrigeration chamber, and a food inlet port is formed at the front end of the refrigeration chamber.

[0032] A door, connected to the housing, for controlling the opening and closing of the food inlet port; the door includes:

[0033] Door shell;

[0034] The inner liner of the door is located on the side of the outer shell of the door near the cooling chamber;

[0035] A support assembly, connected between the door outer shell and the door inner liner, includes two support members disposed opposite to each other;

[0036] An end cap assembly includes two end caps disposed at both ends of the support member and disposed opposite to each other; wherein at least one end cap is detachably connected to the support member by means of a snap-fit ​​connection to improve the structural stability of the door body.

[0037] Compared with the prior art, the advantages and positive effects of this utility model are:

[0038] The refrigeration equipment involved in this application has a snap-fit ​​part on the support of the door body and a corresponding snap-fit ​​part on the end cover.

[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 Figure 1 , Figure 2 The door body includes a door shell 100, a door inner liner 200, a support assembly and an end cap assembly 400 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. The support assembly includes two support members 300 arranged opposite each other. The two support members 300 are respectively located on the left and right sides of the outer door shell 100 and the inner door liner 200. Each support member 300 is arranged vertically to provide support for the door body.

[0077] The end cap assembly 400 includes two end caps respectively disposed at both ends of the support member 300, and the two end caps are respectively horizontally disposed at the upper and lower ends of the door body.

[0078] refer to Figure 3 In this embodiment, at least one end cap has a latching portion 41 extending toward the other end cap at both ends, and a latching portion 340 is provided at the corresponding position of the two support uprights 310. The latching portion 41 and the corresponding latching portion 340 are engaged and connected to achieve a detachable connection between the end cap and the support member 300.

[0079] For ease of understanding, the end cap set at the top of the door is defined as the first end cap 410, and the end cap set at the bottom of the door is defined as the second end cap 420. The first end cap 410 or the second end cap 420 is fixed to the support members 300 on both sides by the above-mentioned snap-fit ​​method.

[0080] The latching portion 41 on the first end cover 410 extends toward the second end cover 420, that is, when the door is in use, the latching portion 41 on the first end cover 410 extends downward.

[0081] The latching part 41 on the second end cover 420 extends toward the first end cover 410. That is, when the door is in use, the latching part 41 on the second end cover 420 extends upward to achieve a detachable connection between the latching part 41 and the support member 300.

[0082] To further explain the connection structure, when the snap-fit ​​part 41 is formed on the first end cover 410, each support member 300 is provided with a snap-fit ​​part 340 on its top to achieve snap-fit ​​with the first end cover 410.

[0083] When the snap-fit ​​portion 340 is formed on the second end cover 420, each support member 300 has a snap-fit ​​portion 340 at its bottom to achieve snap-fit ​​with the second end cover 420.

[0084] Of course, in some embodiments, both the first end cap 410 and the second end cap 420 are provided with a snap-fit ​​part 41, and the first end cap 410 and the second end cap 420 are connected to the support member 300 by snap-fit.

[0085] The support member 300 serves as the outer frame of the door and plays a major supporting role. Compared with traditional plastic door bodies, the support member 300 in this application is made of aluminum alloy.

[0086] Compared to the plastic support component 300, the aluminum alloy support component 300 has better temperature resistance and is less prone to issues such as gaps and glue separation at the connection between the door shell 100, the door inner liner 200 and the support component 300, and frame deformation.

[0087] refer to Figures 4-6 The support member 300 includes a support stand 310 and an inner bend 320 and an outer bend 330 formed on both sides of the support stand 310 and extending toward the same side of the support stand 310. The door shell 100 is connected to the outer bend 330, and the door liner 200 is connected to the inner bend 320.

[0088] 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 door inner liner 200 and the door outer shell 100.

[0089] In some embodiments, the top of the support stand 310 is further formed with an upwardly extending overlapping portion 360. The overlapping portion 360 is generally arc-shaped and is used to overlap the top of the first end cap 410. The outer surface of the overlapping portion 360 is smooth so that the connection between the support stand 310 and the first end cap 410 is smoother and more comfortable, thus improving the user experience.

[0090] Combination Figure 7 An insulated inner cavity 101 is formed between the door shell 100, the door inner liner 200, the end cap assembly 400, and the support assembly, and an insulation layer is provided in the insulated inner cavity 101.

[0091] The insulation layer is used to reduce the transfer of cold air from the cooling cavity to the outside, improve energy utilization, and avoid problems such as condensation on the outside of the door.

[0092] refer to Figures 3-6 , Figures 11-14 The structure and connection of the latching part 340 and the snap-fit ​​part 41 will be described in detail below:

[0093] In some embodiments of this application, the snap-fit ​​portion 340 is formed on the inner side of the support stand 310 near the thermal insulation cavity 101.

[0094] In other words, the snap-fit ​​portions 340 on the two support members 300 are formed on two opposing inner surfaces, and the first end cap 410 and / or the second end cap 420 are connected to the inner side of the support stand 310 by the snap-fit ​​portion 41 to improve the overall integrity of the outer periphery of the door.

[0095] The latching part 41 includes a guide part 402 formed at one end of the end cap and extending downward, and latches 401 formed on both sides of the guide part 402, with a gap formed between the guide part 402 and the latches 401.

[0096] In some embodiments, the snap-fit ​​ends of the two claws 401 face opposite directions, both toward the guide portion 402.

[0097] The latching part 340 includes two latching blocks arranged opposite each other, a guide rail part 344 is formed between the two latching blocks, a guide part 402 is connected to the guide rail part 344, and a latching claw 401 latches into the bottom of the corresponding latching block.

[0098] Specifically, the locking block includes a locking block upright portion 341 and a locking block horizontal portion 342. The locking block upright portion 341 is disposed at an angle on the supporting upright portion 310, and the locking block horizontal portion 342 is formed at an angle at the end of the locking block upright portion 341, and the locking block horizontal portion 342 is located at the end of the locking block upright portion 341 away from the supporting upright portion 310.

[0099] In some embodiments, the inner side of the locking block upright portion 341 is perpendicular to the inner side of the supporting upright portion 310, and the locking block horizontal portion 342 is perpendicular to the locking block upright portion 341, so as to facilitate processing.

[0100] The positions of the two horizontal blocks 342 relative to the vertical blocks 341 are opposite; in other words, the two horizontal blocks 342 extend relative to each other.

[0101] In the installed state, the stand-up part 341 of the locking block is located in the gap between the guide part 402 and the locking gripper.

[0102] A clearance part 403 is provided on the guide part 402, and the horizontal part 342 of the locking block is connected to the clearance part 403.

[0103] For ease of installation, a downwardly inclined guide slope 343 is formed on the card block, and a mating slope 405 is formed on the snap-fit ​​end of the claw 401. Under the action of the mating slope 405, the claw 401 is connected to the card block along the guide slope 343.

[0104] During installation, the snap-fit ​​bevel on the claw 401 contacts the guide bevel 343. As the end cap is installed, the snap-fit ​​bevel gradually expands outward along the guide bevel 343, causing the claw 401 to expand outward. After the snap-fit ​​bevel contacts the outer surface of the snap block upright 341, it moves downward in a straight line until the snap-fit ​​end snaps into the bottom of the snap-fit ​​upright under its own restoring force, completing the connection between the snap-fit ​​part 41 and the snap-fit ​​part 340.

[0105] In other embodiments, the clearance portion 403 is formed between the claw 401 and the limiting portion 404. In the installed state, the two limiting portions 404 between the claw 401 are located between the two horizontal portions 342 of the locking block, which plays a positioning role and ensures the accuracy of assembly.

[0106] The limiting part 404 is also provided with a chamfered surface on the side near the corresponding side claw 401, and a chamfered surface is also formed on the horizontal part 342 of the locking block. When the end cover and the support member 300 are installed, the limiting part 404 is more accurately connected between the two locking horizontal parts under the guidance of the chamfered surface, which is beneficial to the positioning of the end cover.

[0107] The end cap is also provided with a connecting surface that contacts the inner bend 320 and the outer bend 330. The connecting surface is also provided with a connecting protrusion 406 that connects to the inner bend 320 and the outer bend 330. The inner bend 320 and the outer bend 330 are formed with connecting holes 350 that are adapted to the position of the connecting protrusion 406. The connecting protrusion 406 is connected to the corresponding connecting hole 350.

[0108] Along the installation direction of the end cap, the height of the connecting protrusion 406 protruding from the connecting surface gradually decreases, that is, the outer side of the connecting protrusion 406 is formed with a slope.

[0109] Taking the first end cap 410 as an example, the height of the connecting protrusion 406 on the first end cap 410 protruding from the connecting surface gradually decreases from top to bottom. During installation, under the action of the connecting protrusion 406, the inner bend 320 and the outer bend 330 gradually expand outward until the connecting protrusion 406 is completely connected to the connecting hole 350, which helps to improve the stability of the connection between the support member 300 and the end cap.

[0110] Combination Figures 8-10 In some embodiments of this application, an adhesive surface is formed on the outer bend 330, and the door shell 100 is adhered to the adhesive surface by adhesive.

[0111] At least one overflow groove 370 extending along the length of the support 300 is formed on the adhesive surface, the overflow groove 370 being used to hold excess adhesive.

[0112] In some embodiments of this application, there is one overflow groove 370, which is located on the side of the outer bend 330 near the support stand 310. When the door shell 100 is connected to the outer bend 330, adhesive is first applied to the bonding surface, and then the door shell 100 is pressed onto the bonding surface. Excess adhesive overflows into the overflow groove 370 on the bonding surface, so as to avoid insufficient adhesive affecting the bonding firmness, or excessive adhesive overflowing to the outside of the door body and affecting the appearance of the door body.

[0113] In some embodiments of this application, a mounting recess 210 with an opening facing the cooling chamber is formed on the inner door liner 200. The mounting recess 210 is continuously disposed on the periphery of the inner door liner 200, and the door seal 500 is fixed to the inner door liner 200 through the mounting recess 210.

[0114] The door seal 500 is provided with a plug-in part, which is inserted into the mounting recess 210 to realize the detachable connection between the door seal 500 and the door inner liner 200.

[0115] The opening of the mounting recess 210 has a connecting throat with a size smaller than that of the mounting recess 210. The end of the plug part has a plug tip, and sealing wings extending to both sides of the plug tip are also formed. During installation, the plug part is inserted into the mounting recess 210 through the connecting throat. The sealing wings are also located inside the connecting throat. In addition to ensuring the sealing strength of the door seal 500, it also plays a positioning role to prevent the plug part from coming out of the mounting recess 210.

[0116] On the other hand, this application also 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.

The two ends of the end cover are provided with slots that are adapted to the positions of the fastening parts. In the installed state, the fastening parts are engaged in the slots to realize the detachable connection between the support member 300 and the end cover.

[0125] In addition to serving as a connection base for the fastening part, the support stand 310 also serves as a limit and support for the end cover, improving the stability of the connection.

[0126] Method 2:

[0127] At least one end cap has a latching portion 41 extending toward the other end cap at both ends, and a snap-fit ​​portion 340 is provided at the corresponding position of the two support uprights 310. The latching portion 41 and the corresponding snap-fit ​​portion 340 are engaged and connected to realize the detachable connection between the end cap and the support member 300.

[0128] For ease of understanding, the end cap set at the top of the door is defined as the first end cap 410, and the end cap set at the bottom of the door is defined as the second end cap 420. The first end cap 410 or the second end cap 420 is fixed to the support members 300 on both sides by the above-mentioned snap-fit ​​method.

[0129] The latching portion 41 on the first end cover 410 extends toward the second end cover 420, that is, when the door is in use, the latching portion 41 on the first end cover 410 extends downward.

[0130] The latching part 41 on the second end cover 420 extends toward the first end cover 410. That is, when the door is in use, the latching part 41 on the second end cover 420 extends upward to achieve a detachable connection between the latching part 41 and the support member 300.

[0131] To further explain the connection structure, when the snap-fit ​​part 41 is formed on the first end cover 410, each support member 300 is provided with a snap-fit ​​part 340 on its top to achieve snap-fit ​​with the first end cover 410.

[0132] When the snap-fit ​​portion 340 is formed on the second end cover 420, each support member 300 has a snap-fit ​​portion 340 at its bottom to achieve snap-fit ​​with the second end cover 420.

[0133] Of course, in some embodiments, both the first end cap 410 and the second end cap 420 are provided with a snap-fit ​​part 41, and the first end cap 410 and the second end cap 420 are connected to the support member 300 by snap-fit.

[0134] The support member 300 serves as the outer frame of the door and plays a major supporting role. Compared with traditional plastic door bodies, the support member 300 in this application is made of aluminum alloy.

[0135] Method 3:

[0136] The support member 300 includes a support stand 310, an inner bend 320, and an outer bend 330. 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 door shell 100 is connected to the outer bend 330, and the door liner 200 is connected to the inner bend 320.

[0137] The snap-fit ​​portion 340 is formed on the inner side of the support stand 310 near the heat-insulating inner cavity 101.

[0138] In other words, the snap-fit ​​portions 340 on the two support members 300 are formed on two opposing inner surfaces, and the first end cap 410 and / or the second end cap 420 are connected to the inner side of the support stand 310 by the snap-fit ​​portion 41 to improve the overall integrity of the outer periphery of the door.

[0139] The latching part 41 includes a guide part 402 formed at one end of the end cap and extending downward, and latches 401 formed on both sides of the guide part 402, with a gap formed between the guide part 402 and the latches 401.

[0140] The locking ends of the two claws 401 face opposite directions, both towards the guide portion 402.

[0141] The latching part 340 includes two latching blocks arranged opposite each other, a guide rail part 344 is formed between the two latching blocks, a guide part 402 is connected to the guide rail part 344, and a latching claw 401 latches into the bottom of the corresponding latching block.

[0142] Specifically, the locking block includes a locking block upright portion 341 and a locking block horizontal portion 342. The locking block upright portion 341 is perpendicular to the inner side of the supporting upright portion 310, and the locking block horizontal portion 342 is perpendicular to the locking block upright portion 341 to facilitate processing.

[0143] The positions of the two horizontal blocks 342 relative to the vertical blocks 341 are opposite; in other words, the two horizontal blocks 342 extend relative to each other.

[0144] In the installed state, the stand-up part 341 of the locking block is located in the gap between the guide part 402 and the locking gripper.

[0145] For ease of installation, a downwardly inclined guide slope 343 is formed on the card block, and a mating slope 405 is formed on the snap-fit ​​end of the claw 401. Under the action of the mating slope 405, the claw 401 is connected to the card block along the guide slope 343.

[0146] During installation, the snap-fit ​​bevel on the claw 401 contacts the guide bevel 343. As the end cap is installed, the snap-fit ​​bevel gradually expands outward along the guide bevel 343, causing the claw 401 to expand outward.

[0147] After the snap-fit ​​inclined surface contacts the outer side of the snap-fit ​​block upright 341, it moves straight down until the snap-fit ​​end snaps into the bottom of the snap-fit ​​upright under its own restoring force, thus completing the connection between the snap-fit ​​part 41 and the snap-fit ​​part 340.

[0148] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0149] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
