Description

Technical Field

[0001] This invention belongs to the field of refrigerator technology, and particularly relates to a cylindrical refrigerator. Background Technology

[0002] Due to the small size of cylindrical display cases, butterfly doors (see patent CN203848590U) are typically used for easy restocking. These butterfly doors are placed directly on the opening of the case; to restock, the entire butterfly door can be removed. However, because there is no connection between the butterfly door and the case body, the butterfly door is prone to detaching from the case body or even falling off during transport, causing damage. Furthermore, the butterfly door can rotate relative to the case body. When a user opens one side of the door to retrieve goods, if others bump into the upright door, the entire door may rotate, potentially injuring the user who is retrieving goods from the closed side. Summary of the Invention

[0003] In response to the problem that the butterfly doors of existing cylindrical cabinets are prone to detaching from the cabinet body and rotating relative to the cabinet body, this invention provides a cylindrical cabinet in which the butterfly doors can be removed as a whole when replenishing stock. When placed on the cabinet body, they are connected to the cabinet body and are not easy to detach or rotate.

[0004] This invention provides a cylindrical cabinet, comprising:

[0005] The cabinet is cylindrical in shape and has storage compartments for placing items.

[0006] The cabinet opening is located at the top of the cabinet and has an opening that connects to the storage cavity;

[0007] A stop bar is installed at the opening of the cabinet and is located on a diameter of the opening. The length of the stop bar is set along the radial direction of the opening.

[0008] A butterfly door is used to open or close the storage compartment. It is placed at the opening of the cabinet and above the stop bar. It includes two semi-circular door panels that are hinged to each other by a hinge axis. The two door panels are symmetrically arranged with respect to the stop bar. Each door panel has a claw that bends toward the other door panel on the bottom side near the other door panel. The claw rotates around the hinge axis as the door panel it is connected to is opened.

[0009] When the door is closed, the claws on the door extend from one end near the other door to the bottom of the stop bar, so as to block the claws through the stop bar and prevent the door from leaving the cabinet opening; when the door is opened, as the door flips upward, the claws on the door move from the bottom of the stop bar to the side to move away from the stop bar.

[0010] In some embodiments, when both doors are closed, the latches of the two doors intersect, and the stop bar is surrounded by the area enclosed by the latches of the two doors.

[0011] In some embodiments, claws are provided at both ends of the door body near the length of the stop bar.

[0012] In some embodiments, multiple claws are provided at each end of the door body near the length of the stop bar, and the claws of the two door bodies are staggered in the length of the stop bar.

[0013] In some embodiments, a gap is left between the pawl and the outer periphery of the stop bar.

[0014] In some embodiments, a gap is left between the opposite sides of the two door panels for the installation of a hinge shaft. One door panel has a hinge shaft fixing part protruding towards the gap on the side near the gap, and the hinge shaft is fixedly installed in the hinge shaft fixing part. The other door panel has a hinge part protruding towards the gap on the side near the gap, and the hinge part is hinged to the hinge shaft. The diameter of the stop bar is smaller than the width of the gap, and the stop bar is located in the gap and below the hinge shaft. The top edge of the side of one door panel near the gap has a flange part protruding towards the gap, and the flange part is used to cover the gap and the stop bar from the top when both doors are closed.

[0015] In some embodiments, a support is provided at the top of a door, which is used to support the door between two doors when the door is open.

[0016] In some embodiments, the support portion is a support protrusion that protrudes from the top surface of the door.

[0017] In some embodiments, the cylindrical cabinet also includes a crossbeam, which is mounted at the opening of the cabinet opening. The crossbeam is located below the stop bar, and the length direction of the crossbeam is consistent with the length direction of the stop bar. The crossbeam divides the opening of the cabinet opening into two semi-circular openings. A door is used to open or close one semi-circular opening. The bottom edge of the door is provided with a sealing component for sealing the gap between the edge of the semi-circular opening and the bottom surface of the door.

[0018] In some embodiments, the sealing assembly includes a first sealing strip for sealing the gap between the arc edge of the semi-circular opening and the bottom surface of the door, and a second sealing strip for sealing the gap between the straight edge of the semi-circular opening and the bottom surface of the door; the first sealing strip is curved in a semi-circular arc and is attached to the bottom surface of the door along the arc edge of the door. When the door is closed, the lower part of the first sealing strip abuts against the edge of the arc edge of the semi-circular opening formed by the cabinet opening, and the two ends of the first sealing strip abut against the top surfaces of the two ends of the crossbeam in the length direction, respectively; the second sealing strip is straight and is attached to the bottom surface of the door along the straight edge of the door. When the door is closed, the lower part of the second sealing strip abuts against one side of the straight edge of the semi-circular opening formed by the crossbeam.

[0019] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0020] 1. The cylindrical cabinet provided by the present invention, through the cooperation of the claws respectively set on the two doors of the butterfly double door and the stop bar set on the cabinet opening, can remove the butterfly double door as a whole when replenishing the goods. At the same time, when the butterfly double door is placed on the cabinet opening, it can connect the butterfly double door to the cabinet opening, effectively preventing the butterfly double door from leaving the cabinet opening, and preventing the butterfly double door from rotating horizontally relative to the cabinet opening.

[0021] 2. The cylindrical cabinet provided by the present invention has a support part on one of the butterfly-style double doors. When one door is fully opened, the closed door can be supported by the support part, so that the user does not need to support the open door with his hands, making it convenient to take out the goods.

[0022] 3. The cylindrical cabinet provided by the present invention divides the opening of the cabinet opening into two semi-circular openings by setting a crossbeam at the opening of the cabinet opening. Then, the gap between the semi-circular opening and the bottom surface of the corresponding door is sealed by the set sealing component, which can completely seal the opening of the cabinet opening and prevent cold leakage from the gap between the two doors, thus achieving a good sealing effect.

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0049] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0050] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] As attached Figures 1-11 As shown, in an illustrative embodiment of the cylindrical cabinet of the present invention, the cylindrical cabinet includes a cabinet body 1, a cabinet opening 2, a stop bar 4, and butterfly doors 3; the cabinet body 1 is cylindrical and has a storage cavity for placing items; the cabinet opening 2 is located at the top of the cabinet body 1 and has an opening communicating with the storage cavity; the stop bar 4 is mounted at the opening of the cabinet opening 2 and is located on a diameter of the opening, and the length direction of the stop bar 4 is arranged radially along the opening; the butterfly doors 3 are used to open or close the storage cavity, and are placed at the opening of the cabinet opening 2 and above the stop bar 4, and include two semi-circular door panels 31 hinged to each other by a hinge shaft 34. 1. Symmetrically arranged relative to the stop bar 4, each door 31 has a claw 32 bent towards the other door 31 on the bottom side near the other door 31. The claw 32 rotates around the hinge axis 34 as the door 31 it is connected to opens. When the door 31 is closed, the end of the claw 32 on the door 31 near the other door 31 extends to the bottom of the stop bar 4 to block the claw 32 through the stop bar 4 and prevent the door 31 from leaving the cabinet opening 2. When the door 31 is opened, as the door 31 flips upward, the claw 32 on the door 31 moves from the bottom of the stop bar 4 to the side to move away from the stop bar 4.

[0052] The working principle of the above-mentioned cylindrical cabinet is as follows: Figure 9 As shown, when both doors 31 of the butterfly door 3 are closed, the latches 32 of both doors 31 extend below the stop bar 4. When the butterfly door 3 moves upward due to bumps, the stop bar 4 blocks the latches 32, thus preventing the doors 31 from detaching from the cabinet opening 2. Simultaneously, due to the restriction of the latches 32 by the stop bar 4, horizontal rotation of the butterfly door 3 relative to the cabinet opening 2 is effectively prevented. Figure 10 As shown, when one door 31 of the butterfly door 3 is opened (typically in the scenario where a user opens one door 31 to retrieve goods), as the opened door 31 flips upward, the latch 32 on the opened door 31 moves laterally from below the stop bar 4 to move away from below and away from the stop bar 4. The stop bar 4 does not obstruct the opening of the door 31. At the same time, the other door 31 is in the closed state, and the stop bar 4 still blocks the latch 32 of the closed door 31, thereby preventing the door 31 from detaching from the cabinet opening 2 and preventing the butterfly door 3 from rotating horizontally relative to the cabinet opening 2; Figure 11 As shown, when it is necessary to replenish the storage cavity of cabinet 1, both doors 31 are flipped upwards and opened, so that the claws 32 of both doors 31 are removed from below the stop bar 4 and away from the stop bar 4, so that the stop bar 4 is released. At this time, the butterfly door 3 is lifted upwards, so that the butterfly door 3 can be removed from the cabinet opening 2 as a whole, and the opening of the cabinet opening 2 is fully opened, which is convenient for replenishing goods.

[0053] The aforementioned cylindrical cabinet utilizes latches 32 on the two doors 31 of the butterfly-style double doors 3, which cooperate with a stop bar 4 on the cabinet opening 2. The stop bar 4 prevents the butterfly-style double doors 3 from detaching from the cabinet opening 2 by blocking the latches 32, facilitating the transport of the cylindrical cabinet. Furthermore, when both doors 31 are closed or one door 31 is closed, it effectively prevents the butterfly-style double doors 3 from rotating horizontally relative to the cabinet opening 2, avoiding injury to users when retrieving goods due to the horizontal rotation of the butterfly-style double doors 3. Simultaneously, when both doors 31 are open, the stop bar 4 can be released, allowing the butterfly-style double doors 3 to be removed entirely from the cabinet opening 2 for easy restocking. This cylindrical cabinet, while prioritizing restocking portability, achieves a relatively fixed connection between the butterfly-style double doors 3 and the cabinet opening 2 when not restocking, thanks to the simple structure of the latches 32 and the stop bar 4. This design is easy to manufacture, does not significantly increase production costs, occupies little space, and does not affect the viewing window size of the doors 31.

[0054] In this embodiment, as Figure 9 As shown, when both doors 31 are closed, the latches 32 of the two doors 31 intersect, and the stop bar 4 is enclosed within the area formed by the latches 32 of the two doors 31. It should be noted that the latches 32 of the two doors 31 have identical structures and are mirror-symmetrical. By intersecting the latches 32 of the two doors 31, the stop bar 4 can be securely restrained between the latches 32 of the two doors 31, ensuring that the butterfly door 3 will not detach from the cabinet opening 2. Moreover, even when one door 31 is open, the stop bar 4 can still provide sufficient resistance to the latches 32 of the closed door 31, ensuring that the butterfly door 3 will not detach from the cabinet opening 2 when one door 31 is open.

[0055] Preferred, such as Figure 5 As shown, the door body 31 is provided with claws 32 at both ends of the length direction of the stop bar 4 to limit the butterfly door 3 from both ends of the length direction of the stop bar 4, which is more conducive to preventing the butterfly door 3 from rotating horizontally relative to the cabinet opening 2.

[0056] Preferred, such as Figure 5 and Figure 6 As shown, each end of the door body 31 near the length of the stop bar 4 is provided with multiple claws 32, and the claws 32 of the two door bodies 31 are staggered along the length of the stop bar 4. By cooperating with the stop bar 4 through the multiple staggered claws 32, the stop bar 4 can be firmly restricted between the claws 32 of the two door bodies 31, ensuring that the butterfly door 3 will not detach from the cabinet opening 2.

[0057] It should also be noted that, in this embodiment, as Figures 9-11 As shown, there is a gap between the claw 32 and the outer periphery of the stop bar 4, which can prevent the claw 32 and the stop bar 4 from rubbing against each other when the door 31 is flipped, and effectively avoid the stop bar 4 from hindering the flipping of the door 31.

[0058] like Figure 8 and Figure 9 As shown, in this embodiment, a gap is left between the opposite sides of the two door panels 31 for the installation of the hinge shaft 34. One door panel 31 has a hinge shaft fixing part 315 protruding towards the gap on the side near the gap, and the hinge shaft 34 is fixedly installed in the hinge shaft fixing part 315. The other door panel 31 has a hinge part 314 protruding towards the gap on the side near the gap, and the hinge part 314 is hinged to the hinge shaft 34. The diameter of the stop bar 4 is smaller than the width of the gap. The stop bar 4 is located in the gap and below the hinge shaft 34. The top edge of the side of one door panel 31 near the gap has a flange part 316 protruding towards the gap. The flange part 316 is used to cover the gap and the stop bar 4 from the top when both door panels 31 are closed. In this embodiment, by providing a sufficient gap between the two door panels 31, it is convenient to install the hinge shaft 34 and avoids the hinge shaft 34 and its cooperating hinge shaft fixing part 315 and hinge part 314 protruding too high from the top surface of the door panel 31. On the other hand, it leaves space for the installation of the stop bar 4. At the same time, by providing a flange part 316 on one door panel 31 to cover the gap between the two door panels 31 and the stop bar 4, the aesthetics of the top surface of the butterfly door 3 can be maintained.

[0059] Regarding the butterfly-style double door 3, it should also be noted that, as Figures 5-8 As shown, the door body 31 includes a glass 311 and a frame 312 covering the edge of the glass 311. A handle 313 for gripping is provided on the side of the frame 312 away from the hinge axis 34. It should be noted that in this embodiment, the claw 32, the hinge axis fixing part 315, the hinge part 314, and the flange part 316 are all provided on the frame 312. Preferably, the frame 312 and the glass 311 are integrally injection molded to make the frame 312 as narrow as possible and the viewing window of the glass 311 as large as possible.

[0060] like Figure 8 , Figures 12-15 As shown, in this embodiment, a support portion 317 is provided at the top of one door panel 31. The support portion 317 is used to support the door panel 31 between two door panels 31 when it is open. When one door panel 31 is fully open, the closed door panel 31 can be supported by the support portion 317, eliminating the need for the user to manually support the open door panel 31, thus facilitating the retrieval of goods. Specifically, as... Figures 12-15 As shown, in this embodiment, the two door panels 31 are a first door panel 31a and a second door panel 31b, respectively. The top surface of the first door panel 31a is provided with a support portion 317; as shown... Figure 12 and Figure 13 As shown, when the second door 31b is rotated around the hinge axis 34 to the fully open state, the second door 31b is supported on the support portion 317; as Figure 14 and Figure 15As shown, when the first door 31a is rotated around the hinge axis 34 to the fully open state, the support part 317 is supported on the second door 31b. It should be noted that, as... Figure 12 As shown in 14, when the two door panels 31 are supported by the support part 317, the vertical distance between the highest point of the upper door panel 31 and the lower door panel 31 is more than twice the vertical distance between the highest point of the handle 313 and the top surface of the door panel 31, thereby ensuring that the handle 313 will not be squeezed when the two door panels 31 are supported by the support part 317.

[0061] Specifically, such as Figure 8 As shown, in this embodiment, the support portion 317 is a support protrusion protruding from the top surface of the door body 31. Using a support protrusion as the support portion 317 simplifies the structure and makes it more concealed while ensuring support stability, thus maintaining the aesthetic appearance of the butterfly door 3. It should be noted that, as... Figure 7 As shown, the support protrusion extends in a straight line from one end of the top surface of the door 31 to the other end, and its extending direction is consistent with the extending direction of the gap between the two door panels 31. This arrangement allows the support protrusion to provide uniform support to the door 31 and ensures the stability of the support.

[0062] like Figure 13 or Figure 15 As shown, in this embodiment, the side of the support protrusion closest to the hinge shaft 34 is an inclined surface. When the second door 31b is fully open or the first door 31a is fully open, the top surface of the second door 31b abuts against the inclined surface. By setting the supporting side of the support protrusion as an inclined surface, the second door 31b can be completely fitted against the supporting side of the support portion 317, ensuring the stability of the support. Preferably, the inclination angle of the inclined surface is 15° to 80°. If the angle is too large, the upper door 31 will be supported to a high height, making it easy to flip down and fall back, posing a significant safety hazard; if the angle is too small, it may cause the handle 313 to be squeezed.

[0063] In addition, such as Figure 13 or Figure 15 As shown, in this embodiment, the side of the support protrusion that is away from the hinge axis 34 smoothly transitions with the top surface of the first door body 31a, which helps to maintain the aesthetic appearance of the butterfly door 3.

[0064] Regarding the seal between the butterfly-type double door 3 and the cabinet opening 2, it should be noted that, as Figure 3 , Figure 4 , Figure 9 , Figure 16 and Figure 17As shown, in this embodiment, the cylindrical cabinet also includes a crossbeam 5, which is installed at the opening of the cabinet opening 2. The crossbeam 5 is located below the stop bar 4, and the length direction of the crossbeam 5 is consistent with the length direction of the stop bar 4. The crossbeam 5 divides the opening of the cabinet opening 2 into two semi-circular openings. A door 31 is used to open or close one semi-circular opening. The bottom edge of the door 31 is provided with a sealing component 33 for sealing the gap between the edge of the semi-circular opening and the bottom surface of the door 31. By dividing the opening of the cabinet opening 2 into two semi-circular openings by the crossbeam 5, and then sealing the gap between the semi-circular opening and the corresponding bottom surface of the door 31 by the sealing component 33, the opening of the cabinet opening 2 can be completely sealed, preventing cold leakage from the gap between the two doors 31, and the sealing effect is good. It should be noted that when the crossbeam 5 is provided, the shape and length design of the claw 32 should avoid interference with the crossbeam 5, and prevent the crossbeam 5 from affecting the rotation of the door 31. It should also be noted that, as Figure 4 As shown, the cabinet opening 2 is provided with a notch 21 for inserting the crossbeam 5, so as to facilitate the installation of the crossbeam 5.

[0065] Specifically, such as Figure 9 , Figure 16 and Figure 17 As shown, in this embodiment, the sealing assembly 33 includes a first sealing strip 331 for sealing the gap between the arc edge of the semi-circular opening and the bottom surface of the door 31, and a second sealing strip 332 for sealing the gap between the straight edge of the semi-circular opening and the bottom surface of the door 31. The first sealing strip 331 is curved in a semi-circular arc shape and is attached to the bottom surface of the door 31 along the arc edge of the door 31. When the door 31 is closed, the lower part of the first sealing strip 331 abuts against the edge of the arc edge of the semi-circular opening formed by the cabinet opening 2. The second sealing strip 332 is straight and is attached to the bottom surface of the door 31 along the straight edge of the door 31. When the door 31 is closed, the lower part of the second sealing strip 332 abuts against one side of the straight edge of the semi-circular opening formed by the crossbeam 5. In this embodiment, the gap between the semi-circular opening arc edge and the bottom surface of the door body 31 is sealed by the first sealing strip 331, which is curved in a semi-circular arc, abutting against the arc edge of the semi-circular opening; and the gap between the straight edge of the semi-circular opening and the bottom surface of the door body 31 is sealed by the second sealing strip 332, which is straight, abutting against the side of the crossbeam 5.

[0066] To improve the sealing effect, such as Figure 17 and Figure 18 As shown, when the door 31 is closed, both ends of the first sealing strip 331 abut against the top surfaces of both ends of the crossbeam 5 along its length. The crossbeam 5 has grooves 51 at both ends along its length for abutting against the ends of the first sealing strip 331. The abutment of the two ends of the first sealing strip 331 against the ends of the crossbeam 5 along its length ensures a seal at both ends of the crossbeam 5. It should be noted that, as... Figure 6 As shown, the smaller the distance between the corresponding ends of the first sealing strips 331 provided on the two door panels 31, the better, which is beneficial to improving the sealing performance. Preferably, the corresponding ends of the first sealing strips 331 provided on the two door panels 31 touch each other.

[0067] Furthermore, such as Figure 17 As shown, the side of the crossbeam 5 located between the two grooves 51 abuts against the lower part of the second sealing strip 332, and the two ends of the second sealing strip 332 abut against the two ends of the first sealing strip 331 respectively. This arrangement ensures that there are no gaps between the two ends of the second sealing strip 332 and the two ends of the first sealing strip 331, which helps to improve the sealing performance and prevent cold leakage.

[0068] It should be noted that, as Figure 17 As shown, the first sealing strip 331 is preferably an airbag sealing strip, with one side of the airbag sealing strip attached to the bottom surface of the door body 31. By using an airbag sealing strip as the first sealing strip 331, the deformation of the airbag can buffer the downward force when the door body 31 is closed, effectively reducing the noise when closing the door.

[0069] It should be noted that, as Figure 9 As shown, the second sealing strip 332 is preferably a T-shaped sealing strip. The horizontal part of the T-shaped sealing strip is fitted and connected to the bottom surface of the door body 31, and the side of the vertical part of the T-shaped sealing strip abuts against the side of the straight edge of the semi-circular opening formed by the crossbeam 5. Using a T-shaped sealing strip as the second sealing strip 332, the tight fit between the side of the vertical part of the T-shaped sealing strip and the side of the crossbeam 5 helps to improve the sealing performance and prevent cold leakage.

[0070] Through the description of several embodiments of the cylindrical cabinet of the present invention, it can be seen that the embodiments of the cylindrical cabinet of the present invention have at least one or more of the following advantages:

[0071] 1. The cylindrical cabinet provided by the present invention, through the cooperation of the claws 32 respectively provided on the two door bodies 31 of the butterfly double door 3 and the stop bar 4 provided on the cabinet opening 2, can remove the butterfly double door 3 as a whole when replenishing goods. At the same time, when the butterfly double door 3 is placed on the cabinet opening 2, it can connect the butterfly double door 3 to the cabinet opening 2, effectively preventing the butterfly double door 3 from detaching from the cabinet opening 2, and preventing the butterfly double door 3 from rotating horizontally relative to the cabinet opening 2.

[0072] 2. The cylindrical cabinet provided by the present invention has a support part 317 on one of the butterfly doors 31. When one door 31 is fully opened, the closed door 31 can be supported by the support part 317, so that the user does not need to support the open door 31 by hand, which makes it convenient to take out goods.

[0073] 3. The cylindrical cabinet provided by the present invention divides the opening of the cabinet opening 2 into two semi-circular openings by setting a crossbeam 5 at the opening of the cabinet opening 2. Then, the sealing component 33 is set to seal the gap between the semi-circular opening and the bottom surface of the corresponding door 31, which can completely seal the opening of the cabinet opening 2 and prevent cold leakage from the gap between the two doors 31, thus achieving a good sealing effect.
