Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigeration equipment with a rotating shelf assembly. Background Art

[0002] As an indispensable storage device for refrigeration equipment products, the shelf can improve the utilization rate of storage space and

[0003] The convenience of users placing items. In the prior art, the shelves are supported by the support ribs on the inner liner so that the multiple shelves are spaced apart from each other. However, since the support ribs are fixed in the position of the inner liner, the distance between the multiple shelves is relatively fixed. When users need to store taller or larger items, they usually need to disassemble and remove one or more shelves from the inner liner. The shelves need to be placed stably to avoid damage, which makes the use more troublesome and reduces the user experience.

[0004] In order to avoid the trouble of removing the shelves from the refrigerator, some shelves are currently folded and contracted by sliding and folding to release the space of the inner container. For example, the "Foldable Shelf Structure and Refrigerator for Refrigeration Equipment" disclosed in Chinese Patent Publication No. CN102353223B includes a first shelf and a second shelf, wherein the first shelf includes a first decorative strip frame and a first shelf glass embedded in the first decorative strip frame, and the second shelf includes a second decorative strip frame and a second shelf glass embedded in the second decorative strip frame; wherein the first shelf and the second shelf are juxtaposed and can be folded and slid into the lower part of the second decorative strip frame, so that the shelf can be folded.

[0005] In this folding shelf structure, the first shelf can be slid and stored under the second shelf for storage, thereby reducing the impact on the internal storage space. However, the second shelf of this structure is fixed and still occupies storage space at the depth of the refrigeration equipment. When it is necessary to store items of greater depth, it still cannot meet the storage requirements.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0069] In some embodiments of the present application, a refrigeration device is provided, comprising:

[0070] The box body comprises a box shell, which constitutes the outer surface of the box body;

[0071] The box body includes an inner liner component 110, and a storage chamber 120 is defined inside the inner liner component 110;

[0072] In some embodiments of the present application, the storage chamber 120 includes a refrigerating chamber and a freezing chamber arranged up and down to achieve refrigerated and frozen storage of food.

[0073] The door body is connected to the box body, and can be moved relative to the box body to open or close the storage chamber 120, and the food arranged in the storage chamber 120 can be taken out by opening and closing the door body.

[0074] In order to achieve refrigeration and freezing of items stored in the refrigerator and freezer, the refrigeration equipment is also configured with a refrigeration system accordingly.

[0075] The refrigeration system includes a compressor configured to compress a refrigerant;

[0076] a condenser configured to condense the refrigerant;

[0077] an evaporator configured to evaporate the refrigerant condensed by the condenser, wherein the refrigerant evaporated by the evaporator is configured to cool the storage chamber 120;

[0078] The refrigerant circulation loop allows the condensate to circulate in a loop consisting of a compressor, an evaporator, a condenser, a solenoid valve and a throttling device;

[0079] The refrigeration system performs the refrigeration cycle of the refrigeration equipment by using a compressor, a condenser, a solenoid valve, an evaporator and a throttling device.

[0080] A refrigerant circulation loop is formed between the compressor, the condenser, the solenoid valve, the evaporator and the throttling device, so that the refrigerant can circulate among the compressor, the condenser, the solenoid valve, the evaporator and the throttling device.

[0081] The refrigeration cycle consists of a series of processes involving compression, condensation, expansion and evaporation to cool the contents of the cabinet.

[0082] 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.

[0083] The evaporator can cool the items in the cabinet by utilizing the latent heat of evaporation of the refrigerant.

[0084] In order to store and place food in the storage chamber 120 , in some embodiments of the present application, a shelf structure is further provided in the storage chamber 120 .

[0085] The shelf structure includes a fixed bracket 200 and a shelf assembly assembled on the fixed bracket 200 .

[0086] In some embodiments of the present application, the fixing bracket 200 is located in the storage chamber 120 and is assembled and fixed on the inner tank component 110;

[0087] The fixing bracket 200 is an injection-molded bracket, which can be directly integrally injection-molded by an injection molding process.

[0088] The fixing bracket 200 serves to support the entire shelf assembly.

[0089] The shelf assembly includes:

[0090] The first shelf component 300 is rotatably connected to the fixing bracket 200 and can be flipped relative to the fixing bracket 200 to be unfolded or stored to a position parallel to the back plate 111 of the inner liner;

[0091] In some embodiments of the present application, the first shelf component 300 includes a first shelf frame 310 , a first embedding groove is provided in the first shelf frame 310 , and a first shelf glass 320 is embedded in the first embedding groove.

[0092] The first shelf frame 310 is an integral injection-molded part, through which the first shelf glass 320 is assembled and installed. Meanwhile, the first shelf frame 310 is also used to achieve connection and coordination with the fixing bracket 200 .

[0093] The inner tank component 110 includes an inner tank back plate 111, and the first shelf component 300 is arranged near the inner tank back plate 111 and extends along the depth direction of the refrigeration device.

[0094] The depth direction of the refrigeration device in this embodiment refers to the direction from front to back when the refrigeration device is normally placed and used, and the width direction corresponds to the left and right direction.

[0095] The first shelf component 300 is arranged to be rotatably connected to the fixed bracket 200, so that the first shelf component 300 can be rotated relative to the fixed bracket 200 to change its position, such as rotating to unfold or rotating to fold and store.

[0096] When the first shelf component 300 is unfolded, it can be arranged vertically on the back plate 111 of the inner liner for storing items.

[0097] When the first shelf component 300 is rotated for storage, it can be stored to a position parallel to the inner liner back panel 111 to reduce the storage space occupied by the storage chamber 120. When it is parallel to the inner liner back panel 111, it basically does not occupy the depth space of the refrigeration equipment, thereby allowing the refrigeration equipment to store items of a large depth.

[0098] In some embodiments of the present application, when the first shelf component 300 is stored, it fits against the inner liner back plate 111 and is arranged parallel to the inner liner back plate 111 to further reduce the space occupied by the storage chamber 120.

[0099] In some embodiments of the present application, in order to prevent the user from touching the flipped first shelf component 300 when storing items and causing the first shelf component to rotate and fall down, a limiting component 500 is provided on the fixed bracket 200. The limiting component 500 can be used to limit the flipped first shelf component 300 to prevent it from rotating and thus avoid its rotation.

[0100] The second shelf component 400 is connected to the first shelf component 300 and can slide and rotate relative to the first shelf component 300. It can be unfolded or folded to a position that fits the bottom surface of the first shelf component 300 by moving relative to the first shelf component 300.

[0101] In some embodiments of the present application, the second frame component 400 includes a second frame body 410 and a second frame glass 450 , and the second frame glass 450 is embedded in the second frame body 410 to achieve assembly and fixation.

[0102] The second shelf frame 410 is an integral injection-molded part, which can simultaneously achieve the effects of assembling the second shelf glass 450 and connecting the second shelf component 400 and the first shelf component 300 .

[0103] The second shelf component 400 is connected to the first shelf component 300 and together with the first shelf component 300 forms a shelf assembly.

[0104] The shelf assembly has two states, a fully expanded state and a folded storage state.

[0105] When the shelf assembly is in a fully expanded state, the first shelf component 300 is flipped relative to the fixed bracket 200 to a position vertical to the inner liner back panel 111, and the second shelf component 400 is connected to the first shelf component 300 and is flush with the top surface of the first shelf component 300. At this time, items can be placed and stored on the first shelf component 300 and the second shelf component 400 at the same time.

[0106] When the shelf assembly is in a folded storage state, the second shelf component 400 is rotated and folded to the bottom surface of the first shelf component 300, and the first shelf component 300 is stored to a position parallel to the inner liner back plate 111 and is limited by the limiting component 500. The first shelf component 300 and the second shelf component 400 are both parallel to the inner liner back plate 111.

[0107] When storing, the second shelf component 400 can be lifted first, and force can be applied to the second shelf component 400 to make it slide along the first shelf component 300. After sliding into place, it can be rotated relative to the first shelf component 300 to be folded and stored to a position where it is completely in contact with the bottom surface of the first shelf component 300.

[0108] Then, force is applied to the first shelf component 300, which drives the second shelf component 400 stored above it to rotate synchronously relative to the fixed bracket 200, so as to rotate to a position parallel to the inner liner back panel 111 and apply force to the limiting component 500, so that it limits the first shelf component 300, thereby achieving the limiting fixation of the entire shelf assembly after folding.

[0109] When unfolding, force is applied to the limiting component 500 to eliminate the limitation on the first shelf component 300, and then the second shelf component 400 is driven by the first shelf component 300 to flip and open relative to the fixed bracket 200, and then force is applied to the second shelf component 400 to rotate it relative to the first shelf component 300. After it is rotated into place, the second shelf component 400 is slid and pulled to make it enter a position flush with the first shelf component 300. At this time, the first shelf component 300 and the second shelf component 400 are unfolded.

[0110] The shelf assembly structure is configured as a first shelf component 300 and a second shelf component 400 , wherein the first shelf component 300 is configured to be rotatable relative to the fixed bracket 200 , and the second shelf component 400 is configured to be slidable and rotatable relative to the first shelf component 300 .

[0111] When folding and storing, the second shelf component 400 can be slid along the first shelf component 300 and turned over and stored at the bottom of the first shelf component 300, and then the first shelf component 300 and the second shelf component 400 are stored in a position parallel to the back plate 111 of the liner. After storage, the entire shelf assembly does not occupy the deep storage space of the storage chamber 120 at all, thereby increasing the storage space of the storage chamber 120 and meeting the storage needs of users for storing large-depth items.

[0112] In addition, in terms of the storage method, the second shelf component 400 is stored in a sliding and rotating manner. The first shelf component 300 slides along the second shelf component 400 and then rotates, making the storage and folding of the second shelf component 400 relative to the first shelf component 300 smoother and more convenient.

[0113] In some embodiments of the present application, the fixing bracket 200 includes a bracket body 210;

[0114] The first mounting portions 220 formed at both sides of the bracket body 210 near the bottom are used to mount the first shelf component 300;

[0115] First mounting portions 330 are formed on both sides of the first shelf frame 310 . The first mounting portion 330 is formed at one end of the first shelf frame 310 close to the second shelf component 400 and extends downward from the first shelf frame 310 . The first mounting portion 330 is mounted on the first carrying portion 220 .

[0116] The first mounting portion 220 is a first mounting flange formed on both sides of the bracket body 210 , and the first mounting portion 330 is a first mounting protrusion formed on the first shelf frame 310 , which is used to be mounted on the first mounting flange.

[0117] By mounting the first mounting protrusion on the first shelf component 300 on the first mounting flange of the fixing bracket 200, the first shelf component 300 is supported by the first mounting flange to prevent the first shelf component 300 from falling when being unfolded.

[0118] In some embodiments of the present application, a first rotating part 340 is formed on both sides of the first shelf frame 310, and a rotating matching part 230 that matches the first rotating part 340 is formed on the fixed bracket 200, and the first shelf frame 310 is inserted into the rotating matching part 230 through the first rotating part 340.

[0119] The first rotating portion 340 is a first rotating protruding shaft, which is arranged at two sides of the first shelf frame 310 . During molding, it is directly integrally injection-molded with the first shelf frame 310 .

[0120] The rotational fitting portion 230 is a rotational fitting groove formed on the fixed bracket 200 , and the first rotational portion 340 is inserted into the rotational fitting groove to achieve a rotational connection of the first shelf component 300 relative to the fixed bracket 200 .

[0121] A receiving groove is formed between the bracket body 210 and the first mounting flange, and the first shelf frame 310 is arranged in the receiving groove. It is mounted on the first mounting portion 220 through the first mounting portion 330 therebelow. When the first shelf frame 310 is unfolded, its top surface is basically flush with the top surface of the bracket body 210 to enhance the aesthetics of the entire shelf structure.

[0122] In some embodiments of the present application, the fixing bracket 200 includes a second mounting portion 240 arranged along the length direction of the bracket body 210 and adjacent to the first mounting portion 220;

[0123] The second mounting portion 240 is a second mounting flange extending from one side of the bracket body 210 , and the second mounting flange and the first mounting flange are arranged in sequence from front to back along the depth direction of the refrigeration device.

[0124] In some embodiments of the present application, second mounting portions 420 are formed on both sides of the second shelf frame 410 . The second mounting portions 420 are extended along the length direction of the second shelf frame 410 , and the second mounting portions 420 are mounted on the second carrying portion 240 .

[0125] The second mounting portion 420 is a second mounting flange formed from both sides of the second shelf frame 410 , and is used for mounting on the second mounting flange with its bottom surface being in contact with the top surface of the second mounting flange.

[0126] The second mounting portion 240 on the bracket body 210 can provide support for the second shelf component 400 mounted thereon, thereby preventing the second shelf component 400 from falling when being unfolded.

[0127] When in the unfolded state, the top surface of the second shelf frame 410 is substantially flush with the top surface of the support body 210 to ensure the overall aesthetics.

[0128] In some embodiments of the present application, a limited position connection portion 260 is further included, which is used to abut against the end of the first bridging portion 330 to limit the first bridging portion 330 when the first shelf component 300 is unfolded;

[0129] One end of the position-limiting connection portion 260 is connected to the first mounting portion 220 , and the other end is connected to the second mounting portion 240 .

[0130] The limiting connection portion 260 is a limiting connection plate, which is disposed perpendicularly to the first mounting portion 330 and the second mounting portion 420 .

[0131] The height of the second mounting portion 420 is lower than that of the first mounting portion 330 . When the first mounting portion 330 on the first shelf component 300 is rotated and unfolded to a certain position, its end portion is limited by the limiting connection portion 260 .

[0132] In some embodiments of the present application, a flip mating portion 350 is formed on the side of the first mounting portion 330 , and the first mounting portion 220 is extended relative to the first shelf frame 310 toward the side close to the second shelf component 400 .

[0133] Two first mounting portions 330 are formed on both sides of the first shelf frame 310 , and an insertion space is formed between the two first mounting portions 330 .

[0134] The second shelf frame 410 is inserted into the insertion space formed by the two first mounting parts 330 .

[0135] A flip fitting portion 350 is formed on the side of the first mounting portion 330 , and the second rotating portion 430 is formed on the side opposite to the flip fitting portion 350 of the second shelf frame 410 . When mating, the second rotating portion 430 is inserted into the flip fitting portion 350 to slide along the flip fitting portion 350 .

[0136] In some embodiments of the present application, the flip mating portion 350 has a first position and a second position, wherein the first position is higher than the second position.

[0137] The second rotating portion 430 is slidably connected in the flip fitting portion 350 and can rotate relative to the flip fitting portion 350;

[0138] Since the second rotating portion 430 can slide along the flip-fitting portion 350 , it can move back and forth between the first position and the second position.

[0139] When folding, the second shelf component 400 slides downward from the first position to the second position along the flip fitting portion 350 through the second rotating portion 430 and rotates relative to the flip fitting portion 350 to be folded and attached to the bottom surface of the first shelf component 300.

[0140] When the second rotating portion 430 is at the first position of the flipping matching portion 350 , the second shelf component 400 is in an unfolded state. At this time, the second shelf component 400 is relatively high and remains flush with the top surface of the first shelf component 300 .

[0141] When storing, the second shelf member 400 can be pushed so that the second rotating portion 430 slides along the flipping matching portion 350 from the first position to the second position.

[0142] When the second rotating portion 430 is in the second position, it is located below the first shelf frame 310. At this time, its rotation relative to the first shelf frame 310 will not be limited by the first shelf frame 310, and the second shelf component 400 can be rotated relative to the flip matching portion 350 through the second rotating portion 430 for storage.

[0143] When rotating for storage, the second shelf component 400 can be rotated 180 degrees so that it can completely fit with the bottom surface of the first shelf component 300, thereby achieving foldable storage that occupies a small space.

[0144] In some embodiments of the present application, the flip mating portion 350 includes: a first sliding carrying channel 351, which is arranged horizontally, and the first sliding carrying channel 351 is a first sliding carrying long groove opened on the side of the first mounting portion 330, which is a blind groove.

[0145] The second rotating portion 430 can be inserted into the first sliding carrying channel 351 and slide along the first sliding carrying channel 351 .

[0146] The first sliding carrying channel 351 is arranged to be horizontally arranged mainly because when the second shelf component 400 is in the expanded state, the second rotating part 430 is arranged in the first sliding carrying channel 351, and is limited and supported by the first sliding carrying channel 351. The horizontal arrangement of the first sliding carrying channel 351 also ensures that the expanded second shelf component 400 is in a horizontal state to ensure that it is flush with the first shelf component 300.

[0147] The second rotating channel 352 is located below the first sliding carrying channel 351 . The second rotating channel 352 is located below the first shelf frame 310 .

[0148] The second rotating channel 352 is a second rotating elongated groove, which is mainly used for the rotation of the second rotating part 430. It is arranged below the first shelf frame 310 mainly to ensure that the second rotating part 430 will not be interfered and limited by the first shelf frame 310 when sliding into the interior and rotating, thereby ensuring that the second shelf component 400 can be flipped and stored normally.

[0149] The connecting channel 353 is arranged vertically, with one end communicating with the first sliding channel 351 and the other end communicating with the second rotating channel 352 .

[0150] The connecting channel 353 is a transition connecting groove, which is used to connect the first sliding carrying channel 351 and the second rotating channel 352 .

[0151] The connecting channel 353 is arranged vertically so that there is a height difference between the first sliding carrying channel 351 and the second rotating channel 352, ensuring that when the second shelf component 400 is unfolded, it can be located at the upper first sliding carrying channel 351 to be flush with the first shelf component 300, and when subjected to horizontal thrust, it can slide vertically to the lower second rotating channel 352 to perform normal flipping operations.

[0152] In some embodiments of the present application, a mounting support portion 440 is formed at one end of the second shelf frame 410 away from the first shelf frame 310, and a clamping portion 241 is formed at a position corresponding to the second mounting portion 240;

[0153] The erection support portion 440 is an erection support protrusion formed at the end of the first shelf frame 310;

[0154] The locking portion 241 is a locking groove formed on the second carrying portion 240 . When the second shelf component 400 is unfolded, the end thereof away from the first shelf component 300 can be locked in the locking groove by means of a supporting protrusion.

[0155] When the second shelf component 400 is in the unfolded state, one end thereof is mounted in the first sliding carrying channel 351 through the second rotating portion 430 , and the other end is supported and positioned by being clamped in the clamping portion 241 through the mounting support portion 440 .

[0156] The second rotating part 430 and the erecting support part 440 are respectively assembled in the first sliding carrying channel 351 and the clamping part 241 to achieve support and fixation at both ends, thereby ensuring the stability and firmness of the second shelf component 400 in the unfolded state.

[0157] In some embodiments of the present application, the limiting component 500 is rotatably connected to the fixing bracket 200;

[0158] When the shelf assembly is flipped and folded, the limiting component 500 can be rotated relative to the fixed bracket 200 to avoid the shelf assembly;

[0159] When the shelf assembly is folded into place, the limiting component 500 can be rotated and reset when subjected to force to limit the shelf assembly.

[0160] When the first shelf component 300 is rotated and stored, a force may be applied to the limiting component 500 to rotate it, so as to avoid interference with the rotation of the first shelf component 300.

[0161] When the first shelf component 300 is rotated and stored in place, that is, when it is in a position parallel to the rear plate 111 of the inner tank, a force is applied to the limiting component 500 to rotate and extend it to abut against the first shelf component 300 to limit the first shelf component 300.

[0162] In some embodiments of the present application, a rotating mounting portion 251 is formed on the fixing bracket 200;

[0163] Two mounting seats 250 are disposed on the fixing bracket 200 . The two mounting seats 250 are arranged opposite to each other, and an accommodating space is formed between the two mounting seats 250 .

[0164] Each mounting seat 250 is provided with a rotation mounting groove, and two rotation mounting grooves constitute the rotation mounting portion 251 .

[0165] The limiting component 500 includes a limiting component body 510 , and the limiting component body 510 is a limiting block.

[0166] A rotating shaft 520 connected to the stopper body 510 , the rotating shaft 520 is rotatably connected in the rotating mounting portion 251 .

[0167] The rotating shaft 520 is fixedly connected to the limiting block.

[0168] During assembly, the limiting member body 510 is located in the accommodating space, and the two ends of the rotating shaft 520 above it are respectively inserted into the rotating installation grooves of the two mounting seats 250 to realize the rotation of the limiting member 500 relative to the mounting seat 250.
