Description

Technical Field

[0001] This invention belongs to the field of refrigeration technology, and more specifically, relates to a refrigeration device. Background Technology

[0002] Refrigerators typically have multiple shelves where users can place fruits, vegetables, and other items.

[0003] The inner liner of the refrigerator has supporting ribs to support the shelves, which can easily cause the shelves to tilt or even fall off. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, the present invention proposes a refrigeration device, comprising: an inner liner, on which a supporting rib and a supporting part are provided; a shelf, wherein the supporting rib and the supporting part are used to support two opposing sides of the shelf; a connecting part, provided on the shelf, the connecting part being connected to the supporting rib, wherein an opening is provided on one side of the inner liner, the side of the inner liner facing the opening is the rear sidewall of the inner liner, and the connecting part is used to restrict the side of the shelf facing the rear sidewall from tilting upward.

[0006] The refrigeration equipment provided by this invention is illustrated by a shelf with four corners. Support ribs support two adjacent corners, and a support portion supports a third corner, leaving the fourth corner unsupported, which can cause the shelf to tilt. By providing a connecting portion on the shelf and connecting it to the support ribs, the connecting portion secures the shelf to the support ribs, preventing it from easily separating and thus reducing its wobbling relative to the ribs. The connecting portion acts as an anti-tilting structure, preventing the shelf from tilting and falling off, thereby improving the stability of the shelf when carrying fruits and vegetables.

[0007] In one possible application, the inner liner includes an air duct, with a support portion disposed on the air duct.

[0008] In addition, the refrigeration equipment according to the above-described technical solution provided by the present invention may also have the following additional technical features:

[0009] In the above technical solution, the shelf includes a first side wall and a second side wall, which are two opposite side walls of the shelf, with the first side wall facing the rear side wall. The distance between the connecting part and the first side wall is smaller than the distance between the connecting part and the second side wall. The connecting part is close to the back of the inner liner, which effectively prevents the other corner, which is located on the diagonal line of the suspended corner, from lifting up. The problem of preventing the shelf from lifting up is solved by a single connecting part.

[0010] In the above technical solution, the shelf is located on the top wall of the support rib, and a part of the connecting part is in contact with the bottom wall of the support rib.

[0011] In this technical solution, since a part of the support rib is in contact with the bottom wall of the support rib, the support rib limits the connection part, preventing the connection part from moving upward relative to the support rib. Since the connection part is connected to the shelf, when the connection part cannot move upward, the shelf cannot move upward either, effectively preventing the shelf from tilting.

[0012] In any of the above technical solutions, the support rib is provided with an assembly hole, a part of the support rib passes through the assembly hole and contacts the bottom wall of the support rib.

[0013] In this technical solution, an assembly hole is provided on the support rib. After the connecting part passes through the assembly hole, it contacts the bottom wall of the support rib. The connecting part and the bottom wall of the support rib engage with each other, making it difficult for the connecting part to move relative to the support rib, thereby restricting the rising of the connecting part relative to the support rib and preventing the shelf from tilting.

[0014] In other solutions, the connecting part can be routed around the support rib on the side and then contact the bottom wall of the support rib.

[0015] In any of the above technical solutions, the support rib includes: a first rib and a second rib, the first rib and the second rib being spaced apart, and an assembly hole being formed between the first rib, the second rib and the inner liner; a portion of the connecting part is located in the assembly hole, and at least a portion of the connecting part located in the assembly hole is in contact with the first rib or the second rib to support the connecting part.

[0016] In this technical solution, compared to directly drilling holes in the support ribs, the first and second ribs are less prone to breakage, improving the structural stability of the support ribs and ensuring that the support ribs can stably support the shelf.

[0017] In any of the above technical solutions, a portion of the connecting part located inside the assembly hole is in contact with the side wall of the first rib and the side wall of the second rib.

[0018] In this technical solution, the first rib and the second rib can simultaneously support both sides of the connecting part, making it less likely for the connecting part to wobble relative to the first rib and the second rib, thereby further improving the assembly stability of the shelf.

[0019] In any of the above technical solutions, the first rib and the second rib clamp the connecting part.

[0020] In this technical solution, the connecting part is clamped by the first rib and the second rib, so that the connecting part can be stably connected with the first rib and the second rib, thereby further improving the limiting stability of the connecting part on the shelf.

[0021] In any of the above technical solutions, the bottom wall of the supporting rib is inclined relative to the side wall of the inner liner.

[0022] In this technical solution, the bottom wall of the support rib is inclined relative to the side wall of the inner liner, so the support rib is not easily deformed relative to the side wall of the inner liner, thereby improving the load-bearing stability of the support rib on the shelf and enhancing the storage capacity of the refrigeration equipment.

[0023] In any of the above technical solutions, the connecting part is provided with a contact end face, which is inclined relative to the side wall of the inner liner so that the contact end face fits against the bottom wall of the support rib.

[0024] In this technical solution, in order to ensure that the supporting rib stably limits the connection, the contact end face in the connection is also inclined, and the inclination angle of the connection is the same as the inclination angle of the bottom wall of the supporting rib, so as to ensure that the contact end face and the bottom wall of the supporting rib can fit tightly together.

[0025] When the contact end face is in contact with the bottom wall of the support rib, the contact end face and the support rib have a large contact area, which can improve the connection stability between the connecting part and the support rib, thereby ensuring that the support rib can stably limit the connection part, and thus improve the limiting stability of the shelf.

[0026] In any of the above technical solutions, one side of the support rib is connected to the inner liner along the width direction of the support rib; the width of the connection is greater than or equal to the width of the support rib.

[0027] In this technical solution, the width of the connecting part is limited to be greater than or equal to the width of the supporting rib, so that the connecting part and the supporting rib have a larger contact area, thereby improving the contact stability between the connecting part and the supporting rib, which is beneficial to improving the limiting stability of the supporting rib on the connecting part.

[0028] In any of the above technical solutions, the width direction of the shelf extends from the first side wall to the second side wall; along the width direction of the shelf, at least one connecting part is provided on the shelf.

[0029] In this technical solution, at least one connecting part is provided on the shelf in the width direction. By increasing the number of connecting parts, the connection stability between the connecting part and the supporting rib can be improved, thereby improving the limiting stability of the shelf.

[0030] In any of the above technical solutions, the connecting part is a hollow structure.

[0031] In this technical solution, the connecting part is connected to the shelf, and the connecting part is designed as a hollow structure, which reduces the overall weight of the connecting part and the shelf, making it easier for users to access and place items on the shelf. Moreover, because the connecting part is a hollow structure, it saves on material costs.

[0032] In any of the above technical solutions, the refrigeration equipment further includes: a locking member, a first mounting hole on the connecting part, a second mounting hole on the support rib, and the locking member passing through the first mounting hole and the second mounting hole to connect the connecting part to the support rib.

[0033] In this technical solution, the locking component locks the connecting part to the support rib, making it less likely for the connecting part to wobble relative to the support rib, thus allowing the shelf to be placed stably on the support rib.

[0034] In any of the above technical solutions, the connecting part is provided with a first magnetic attraction part, and the supporting rib is provided with a second magnetic attraction part, and the first magnetic attraction part and the second magnetic attraction part attract each other.

[0035] In this technical solution, the connecting part is fixed to the support rib under the action of magnetic force, so that the shelf can be stably placed on the support rib.

[0051] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0053] The following reference Figures 1 to 11 A refrigeration device is described according to some embodiments of the present invention.

[0054] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an embodiment of the present invention, a refrigeration device is provided, including: an inner liner 100, a shelf 400, and a connecting part 500. The inner liner 100 is provided with a support rib 200 and a support part 600, which support the opposite sides of the shelf 400. The connecting part 500 is disposed on the shelf 400 and connected to the support rib 200. An opening is provided on one side of the inner liner 100, and the side of the inner liner 100 facing the opening is the rear sidewall of the inner liner 100. The connecting part 500 is used to restrict the side of the shelf 400 facing the rear sidewall from tilting upwards.

[0055] The refrigeration equipment provided in this embodiment has a support rib 200 and a support part 600 on the inner liner 100. The support rib 200 can support one side of the shelf 400. Specifically, the support part 600 is provided on the side wall of the air duct 300. In the following embodiment, the support part 600 is provided on the air duct 300 for illustrative purposes. The support part 600 supports the other side of the shelf 400. The support rib 200 and the support part 600 support both sides of the shelf 400 at the same time, so that the shelf 400 can be used by users to carry fruits and vegetables.

[0056] For refrigeration equipment with a wide width, if the shelves 400 are supported by the support ribs 200 on the opposite side walls of the inner liner 100, the shelf 400 is prone to breakage due to its long length and limited load-bearing capacity in the middle. This can occur when heavy fruits and vegetables are placed on it. Therefore, at least two shelves 400 are provided, supported by support parts 600 on the side walls of the air duct 300. For example, when there are two shelves 400, since part of the inner liner 100 does not cover the side wall of the air duct 300, and the air duct 300 is usually located in the middle of the back of the inner liner 100, support parts 600 can be provided on the side walls of the air duct 300 to support both shelves 400.

[0057] Taking a shelf 400 with four corners a, b, c, and d as an example, the support rib 200 can support corners a and b of the shelf 400, the support part 600 can support corner c, and corner d will be in a suspended state. When a heavy object is placed on the shelf 400, corner d will be subjected to a downward force, while corner b will tend to tilt upward. By providing a connecting part 500 on the shelf 400 and connecting the connecting part 500 to the support rib 200, the connecting part 500 can fix the shelf 400 to the support rib 200, so that corner c will not tilt upward, and therefore corner d will not drop. This makes it less likely for the shelf 400 to sway relative to the support rib 200. The connecting part 500 acts as an anti-tilting structure, which makes it less likely for the shelf 400 to tilt, prevents the shelf 400 from falling off, and improves the stability of the shelf 400 in carrying fruits and vegetables.

[0058] In the above embodiment, the shelf 400 includes a first sidewall 410 and a second sidewall 420. The first sidewall 410 and the second sidewall 420 are two opposite sidewalls of the shelf 400, with the first sidewall 410 facing the rear sidewall. The distance between the connecting portion 500 and the first sidewall 410 is smaller than the distance between the connecting portion 500 and the second sidewall 420.

[0059] The first side wall 410 is a side wall of the shelf 400 facing the air duct 300, and the second side wall 420 is a side wall of the shelf 400 away from the air duct 300.

[0060] When the support rib 200 and support portion 600 support the shelf 400, assuming the shelf 400 has four corners, the support portion 600 supports one corner, the support rib 200 supports two corners, and one corner is suspended. Therefore, the corner diagonally opposite the suspended corner is prone to warping. With only one connecting portion 500, the distance between the connecting portion 500 and the first side wall 410 is less than the distance between the connecting portion 500 and the second side wall 420, meaning the connecting portion 500 is close to the back of the inner liner 100. This effectively prevents the corner diagonally opposite the suspended corner from warping, thus preventing the shelf 400 from warping through a single connecting portion 500. Figure 5 As shown, in any of the above embodiments, the shelf 400 is located on the top wall of the support rib 200, and a portion of the connecting portion 500 contacts the bottom wall 240 of the support rib 200. The shelf 400 is placed on the bottom wall 240 of the support rib 200, so that the support rib 200 can support the shelf 400. The contact between the portion of the connecting portion 500 and the bottom wall 240 of the support rib 200 limits the connection portion 500, making it difficult for the shelf 400 to separate from the support rib 200.

[0061] In related technologies, when a shelf tilts, a portion of the shelf moves upward, causing the shelf to separate from the support rib. In this invention, because a portion of the support rib 200 contacts the bottom wall 240 of the support rib 200, the support rib 200 limits the connecting portion 500, preventing the connecting portion 500 from moving upward relative to the support rib 200. Since the connecting portion 500 is connected to the shelf 400, when the connecting portion 500 cannot move upward, the shelf 400 also cannot move upward, effectively preventing the shelf 400 from tilting.

[0062] like Figure 5 As shown, in any of the above embodiments, the support rib 200 is provided with an assembly hole 210, a portion of the support rib 200 passes through the assembly hole 210 and contacts the bottom wall 240 of the support rib 200. The connecting portion 500 is connected to the shelf 400, and since the shelf 400 is located on the bottom wall 240 of the support rib 200, a portion of the connecting portion 500 is located above the top wall of the support rib 200. In order for the connecting portion 500 to contact the bottom wall 240 of the support rib 200, a portion of the connecting portion 500 needs to extend beyond the support rib 200.

[0063] Specifically, in this solution, an assembly hole 210 is provided on the support rib 200. After the connecting part 500 passes through the assembly hole 210, it contacts the bottom wall 240 of the support rib 200. The connecting part 500 and the bottom wall 240 of the support rib 200 are engaged with each other, making it difficult for the connecting part 500 to move relative to the support rib 200, thereby restricting the rising of the connecting part 500 relative to the support rib 200 and preventing the shelf 400 from tilting.

[0064] In other solutions, the connecting part 500 can be bypassed by the support rib 200 on the side of the support rib 200 and then contact the bottom wall 240 of the support rib 200.

[0065] Combination Figure 5 , Figure 10 and Figure 11 As shown, in any of the above embodiments, the support rib 200 includes a first rib 220 and a second rib 230, which are spaced apart. An assembly hole 210 is formed between the first rib 220, the second rib 230, and the inner liner 100. A portion of the connecting portion 500 is located within the assembly hole 210, and at least a portion of the connecting portion 500 located within the assembly hole 210 is in contact with either the first rib 220 or the second rib 230 to support the connecting portion 500.

[0066] In this embodiment, the support rib 200 is composed of a first rib 220 and a second rib 230, which are separated from each other. That is, the first rib 220 and the second rib 230 are spaced apart, and the side of the first rib 220, the side of the second rib 230 and the inner liner 100 form an assembly hole 210.

[0067] If holes are directly drilled in the support rib 200, the structural strength at the drilling point will be low, and the support rib 200 will be prone to breakage. In this solution, the support rib 200 is divided into a first rib 220 and a second rib 230. The first rib 220 and the second rib 230 have the same width. Compared with drilling holes directly in the support rib 200, the first rib 220 and the second rib 230 are less likely to break, thus improving the structural stability of the support rib 200 and ensuring that the support rib 200 can stably support the shelf 400.

[0068] When the connecting part 500 is assembled with the support rib 200, the connecting part 500 contacts the side of the first rib 220 or the second rib 230, and the first rib 220 and the second rib 230 support the connecting part 500, further improving the connection stability between the connecting part 500 and the support rib 200.

[0069] In any of the above embodiments, a portion of the connecting part 500 located in the assembly hole 210 is in contact with the side wall of the first rib 220 and the side wall of the second rib 230.

[0070] The first rib 220 and the second rib 230 can simultaneously support both sides of the connecting part 500, making it less likely for the connecting part 500 to wobble relative to the first rib 220 and the second rib 230, thereby further improving the assembly stability of the shelf 400.

[0071] like Figure 5 As shown, the support end face 520 on the connecting part 500 is in contact with the second rib 230.

[0072] In any of the above embodiments, the first rib 220 and the second rib 230 clamp the connecting portion 500.

[0073] The connecting part 500 is clamped by the first rib 220 and the second rib 230, so that the connecting part 500 can be stably connected with the first rib 220 and the second rib 230, thereby further improving the limiting stability of the connecting part 500 on the shelf 400.

[0074] Combination Figure 4 and Figure 5 As shown, in any of the above embodiments, the bottom wall 240 of the support rib 200 is inclined relative to the side wall of the inner liner 100.

[0075] In this embodiment, the support rib 200 supports the shelf 400. In order to ensure that fruits and vegetables can be stably placed on the shelf 400, the support rib 200 needs to have sufficient structural strength so that the support rib 200 can stably support the shelf 400.

[0076] The bottom wall 240 of the support rib 200 is inclined, and the angle between the bottom wall 240 of the support rib 200 and the side wall of the inner liner 100 is an obtuse angle. Compared with the case where the angle between the bottom wall 240 of the support rib 200 and the side wall is a right angle, this solution improves the structure of the support rib 200 by setting the bottom wall 240 of the support rib 200 inclined relative to the side wall of the inner liner 100. The support rib 200 is less likely to deform relative to the side wall of the inner liner 100, thereby improving the load-bearing stability of the support rib 200 on the shelf 400 and enhancing the storage capacity of the refrigeration equipment.

[0077] Combination Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, in any of the above embodiments, the connecting part 500 is provided with a contact end face 510, which is inclined relative to the side wall of the inner liner 100 so that the contact end face 510 fits against the bottom wall 240 of the support rib 200.

[0078] In this embodiment, the contact end face 510 on the connecting part 500 is in contact with the bottom wall 240 of the support rib 200. The bottom wall 240 limits the contact end face 510, so the connecting part 500 is not easy to move upward relative to the support rib 200, thereby limiting the shelf 400 from tilting relative to the support rib 200.

[0079] The bottom wall 240 of the support rib 200 is inclined. In order to ensure that the support rib 200 stably limits the connection part 500, the contact end face 510 in the connection part 500 is also inclined. The inclination angle of the connection part 500 is the same as the inclination angle of the bottom wall 240 of the support rib 200, so as to ensure that the contact end face 510 and the bottom wall 240 of the support rib 200 can fit tightly together.

[0080] When the contact end face 510 is in contact with the bottom wall 240 of the support rib 200, the contact end face 510 and the support rib 200 have a large contact area, which can improve the connection stability between the connecting part 500 and the support rib 200, thereby ensuring that the support rib 200 can stably limit the connecting part 500, and thus improve the limiting stability of the shelf 400.

[0081] In any of the above embodiments, along the width direction of the support rib 200, one side of the support rib 200 is connected to the inner liner 100, and the width of the connecting part 500 is greater than or equal to the width of the support rib 200.

[0082] In this embodiment, along the width direction of the support rib 200, one side of the support rib 200 is connected to the inner liner 100, and the other side of the support rib 200 is away from the inner liner 100. Along the width direction of the support rib 200, the width of the connecting portion 500 is greater than or equal to the width of the support rib 200. The larger width of the connecting portion 500 ensures higher structural strength, making it less prone to breakage under stress and guaranteeing structural stability.

[0083] Furthermore, by limiting the width of the connecting portion 500 to be greater than or equal to the width of the supporting rib 200, the connecting portion 500 and the supporting rib 200 have a larger contact area, thereby improving the contact stability between the connecting portion 500 and the supporting rib 200, which is beneficial to improving the limiting stability of the supporting rib 200 on the connecting portion 500.

[0084] Combination Figure 6 and Figure 8 As shown, in any of the above embodiments, the width direction of the shelf 400 extends from the first sidewall 410 to the second sidewall 420, and at least one connecting portion 500 is provided on the shelf 400 along the width direction of the shelf 400.

[0085] In this embodiment, along the width direction of the shelf 400, the shelf 400 has two side walls, namely a first side wall 410 and a second side wall 420.

[0086] In the width direction of the shelf 400, at least one connecting part 500 is provided on the shelf 400. By increasing the number of connecting parts 500, the connection stability between the connecting part 500 and the support rib 200 can be improved, thereby improving the limiting stability of the shelf 400.

[0087] In any of the above embodiments, the connecting part 500 is a hollow structure.

[0088] In this embodiment, the connecting part 500 is connected to the shelf 400. The connecting part 500 is designed as a hollow structure, which reduces the overall weight of the connecting part 500 and the shelf 400, making it easier for the user to access the shelf 400. Furthermore, the hollow structure of the connecting part 500 saves on material costs.

[0089] In any of the above embodiments, the refrigeration device further includes: a locking member, a first mounting hole on the connecting portion 500, a second mounting hole on the support rib 200, and the locking member passing through the first mounting hole and the second mounting hole to connect the connecting portion 500 to the support rib 200.

[0090] The locking component locks the connecting part 500 to the support rib 200, making it less likely for the connecting part 500 to wobble relative to the support rib 200, thus allowing the shelf 400 to be stably placed on the support rib 200.

[0091] In one possible application, the first and second mounting holes can be pin holes, and the locking element can be a pin. Alternatively, the first mounting hole can be a through hole, the second mounting hole can be a threaded hole, and the locking element can be a locking bolt.

[0092] In any of the above embodiments, the connecting part 500 is provided with a first magnetic attraction part, and the supporting rib 200 is provided with a second magnetic attraction part, and the first magnetic attraction part and the second magnetic attraction part attract each other.

[0093] The first magnetic part and the second magnetic part can be magnets, so the first magnetic part and the second magnetic part can attract each other. Under the action of magnetic force, the connecting part 500 is fixed on the support rib 200, so that the shelf 400 can be stably placed on the support rib 200.

[0094] In this invention, the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "install," "connect," "link," and "fix" should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "link" can be a direct connection or an indirect connection through an intermediate medium.
