Detailed Implementation Methods

[0068] To provide a better understanding of the purpose, structure, features, and functions of this application, detailed descriptions are provided below with reference to specific embodiments.

[0069] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "height", "lateral", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0070] In this embodiment, the width direction of drawer 2 is denoted as the x-direction, the depth direction of drawer 2 as the y-direction, and the height direction of drawer 2 as the z-direction. When drawer 2 is installed in a refrigeration appliance (such as...) Figure 1 As shown, the x-direction is parallel to the width direction of the refrigeration appliance, the y-direction is parallel to the depth direction of the refrigeration appliance, and the z-direction is parallel to the height direction of the refrigeration appliance.

[0071] It should be pointed out that, Figure 1 This example demonstrates a multi-door refrigerator. In practical applications, the structure of this implementation scheme can also be applied to other types of refrigeration appliances, such as side-by-side refrigerators, single-door refrigerators, freezers, and refrigerator cabinets. Figures 1 to 18 Various embodiments of the individual components described can be combined with each other in any given manner to achieve the advantages of this application.

[0072] This invention provides a refrigeration appliance 100, including a housing 1, which includes an inner wall 12 and an outer wall 13. The inner wall 12 defines a storage chamber 11, which has a front opening. A drawer 2 is located inside the storage chamber 11 and can be pulled out or pushed back into the storage chamber 11. A slide rail assembly 3 is constructed on the side 26 of the drawer 2. A guide rail assembly 4 is disposed inside the storage chamber 11 and cooperates with the slide rail assembly 3 to support the drawer 2. The guide rail assembly 4 includes a first support member 41, which cooperates with a support surface 6 of the drawer 2.

[0073] The guide rail assembly 4 also includes a second support member 42, which engages with another support surface that is disposed on the drawer 2 and is different from the support surface 6.

[0074] In one embodiment of this application, such as Figure 3 As shown, drawer 2 may include a bottom wall 21, a front wall 22, a rear wall 23, and a pair of side walls 24, as well as a storage space enclosed by the bottom wall 21, the front wall 22, the rear wall 23, and the pair of side walls 24. Rollers 25 are provided at the rear of the side walls 24 of drawer 2.

[0075] The drawer 2 is provided with a slide rail assembly 3 on its side. Specifically, the slide rail assembly 3 includes a support surface 6, i.e., a first support surface 31, on the side wall 24 of the drawer 2 that protrudes and extends toward the guide rail assembly 4.

[0076] In one embodiment of this application, the guide rail assembly 4 is located inside the storage chamber 11. The guide rail assembly 4 has a slide rail 46 extending along the depth direction y of the storage chamber 11, and the roller 25 is adapted to slide along the slide rail 46. There can be two guide rail assemblies 4, which are arranged opposite to each other on the inner wall 12 of the housing 1.

[0077] The guide rail assembly 4 can be made of plastic material.

[0078] Example 1

[0079] like Figures 2 to 4 As shown, the guide rail assembly 4 is provided with a first support member 41. The first support member 41 is constructed on the side of the guide rail assembly 4 facing the drawer 2. In the embodiments of this application, the first support member 41 is preferably constructed as a roller member.

[0080] The drawer includes a first support surface 31. Specifically, the drawer 2's slide rail assembly 3 has a first support surface 31, which is supported on a first support member 41. When the drawer 2 slides within the storage compartment 11, the first support surface 31 slides on the first support member 41, thereby supporting the movement of the drawer 2 within the storage compartment 11. In other embodiments, the first support member 41 may be configured as an arcuate protrusion or other adaptable rolling structure.

[0081] To enhance the load-bearing capacity of the guide rail assembly, a second support member 42 is provided on the guide rail assembly 4. The second support member 42, like the first support member 41, is constructed on the side of the guide rail assembly 4 facing the drawer 2. In the embodiments of this application, the second support member 42 is constructed as a roller. In other embodiments, the second support member 42 may be constructed as an arc-shaped protrusion or other adaptable rolling structure.

[0082] In this specific embodiment, the first support member 41 and the second support member 42 are arranged at intervals along the height direction of the drawer 2. Specifically, the second support member 42 is located above the slide opening 461, the top of the first support member 41 is higher than the bottom wall of the slide 46, the top of the second support member 42 is higher than the top wall of the guide rail assembly 4, and the first support member 41 is located at the slide opening 461 and directly above the first support member 41. Preferably, the distance between the second support member 42 and the first support member 41 is not greater than the height of the first support member 41 or the second support member 42, which helps to reduce the space occupied by the guide rail assembly in the storage room.

[0083] like Figure 2As shown, the guide rail assembly 4 is provided with a mounting surface for mounting the first support member 41 and the second support member 42. The first support member 41 and the second support member 42 are mounted on the front side of the guide rail assembly 4 by fasteners. The first support member 41 and the second support member 42 are mounted on the side of the guide rail assembly 4 facing the drawer 2. The side of the first support member 41 facing the drawer 2 and the side of the second support member 42 facing the drawer 2 are on the same surface, that is, the first support member 41 and the second support member 42 protrude the same distance in the direction of the drawer 2.

[0084] An opening 43 is defined between the first support member 41 and the second support member 42. At least a portion of the slide rail assembly 3 can enter the slide rail assembly 4 through the opening 43. Specifically, the rear part of the support rib of the slide rail assembly 3 forming the first support surface 31 can enter the slide rail assembly 46 of the guide rail assembly 4 through the opening 43 and be supported on the first support member 41.

[0085] In this specific embodiment, when both the first support member 41 and the second support member 42 are constructed as rollers, the first support member 41 has a rotation center line A1, and the second support member 42 has a rotation center line A2. The center lines A1 and A2 of the first roller are on the same vertical plane along the height direction of the drawer 2. In other embodiments, the center point of the first support member 41 and the center point of the second support member 42 may not be on the same vertical plane.

[0086] See appendix Figure 3 The drawer 2 also has a second support surface on its side, which is different from the first support surface 31 and cooperates with the second support member 42. Specifically, the slide rail assembly 3 includes a second support surface 32 that cooperates with the second support member 42. The first support surface 31 and the second support surface 32 are located on the same side 26 of the drawer 2 and extend in a direction away from the drawer 2. In the embodiments of this application, the distance that the first support surface 31 extends from the side 26 is the same as the distance that the second support surface 32 extends from the side 26. This makes the force on the first support surface and the second support surface more uniform.

[0087] Preferably, the second support surface 32 is constructed as the lower surface of another support rib of the slide rail assembly 3, located above the first support surface 31. The height of the gap between the first support surface 31 and the second support surface 32 is suitable for accommodating the second support member 42, that is, the second support member 42 can slide or roll within the space defined by the two support ribs.

[0088] Preferably, the first support surface 31 and the second support surface 32 are arranged parallel to each other. Specifically, the support path defined by the first support surface 31 extending along the drawer depth direction is consistent with the support path defined by the second support surface 32 extending along the drawer depth direction, so that the drawer 2 can move smoothly within the storage compartment 11.

[0089] The length of the second support surface 32 extending along the depth direction of the drawer 2 is greater than the length of the first support surface 31 extending along the depth direction of the drawer 2. Specifically, the first support surface 31 includes a first front support surface 311, a first rear support surface 312, and a first stop groove 313 connecting the first front support surface 311 and the first rear support surface 312. The second support surface 32 includes a second front support surface 321, a second rear support surface 322, and a second stop groove 323 connecting the second front support surface 321 and the second rear support surface 322. The length of the second rear support surface 322 is greater than the length of the first rear support surface 312.

[0090] like Figures 5A to 5C As shown, in Figure 5A The "front" and "back" markings refer to the direction of movement towards the user when operating the drawer, which is considered the front and the direction away from the user, which is considered the back.

[0091] When installing the drawer, the drawer 2 is tilted so that the rollers 25 enter the front side of the slide rail 46 from the slide rail opening 461 behind the second support member 42. Then the drawer 2 is rotated to a near-horizontal position so that the support rib forming the first support surface 31 is inserted between the first support member 41 and the second support member 42 to install the drawer on the guide rail assembly 4.

[0092] When drawer 2 is pulled out of storage compartment 11, the first front support surface 311 engages with the first support member 41, and the second front support surface 321 engages with the second support member 42, allowing drawer 2 to move smoothly within storage compartment 11. When drawer 2 is pulled out to a certain position, the first stop groove 313 abuts against the first support member 41, and the second stop groove 323 abuts against the second support member 42, thereby limiting drawer 2 to its current open position. Compared to the prior art, which uses only one stop groove to engage with the support member to limit the open position of drawer 2, the present application's technical solution uses two stop grooves to engage with the guide rail assembly to limit the drawer to a preset position, improving the guide rail assembly's load-bearing capacity for the drawer.

[0093] When drawer 2 is pulled out of storage compartment 11, the first rear support surface 312 disengages from the first support member 41, but the roller 25 has not yet reached the slide opening 461. At this time, the drawer cannot be taken out of storage compartment. Therefore, the longer second rear support surface 322 cooperates with the second support member 42 to continue supporting the movement of drawer 2 in storage compartment 11 until the roller 25 of drawer 2 disengages from the slide opening 461 of slide 46, at which point the drawer can be completely taken out of storage compartment.

[0094] Example 2

[0095] In a specific embodiment, such as Figures 6 to 8As shown, the guide rail assembly 4 is provided with a first support member 41 and a second support member 42. The first support member 41 and the second support member 42 are constructed as roller members. In other embodiments, the first support member 41 and / or the second support member 42 may be constructed as an arc-shaped protrusion or other adaptable rolling structure.

[0096] The first support member 41 and the second support member 42 are both constructed below the slide opening 461 of the slide rail 46. At this time, the projection portions of the first support member 41 and the second support member 42 along the width direction of the drawer 2 overlap. As a result, the first support member 41 and the second support member 42 can evenly distribute the weight of the drawer.

[0097] Specifically, the second support member 42 partially intersects with the first support member 41 and is located in front of the first support member 41. The overlapping portion of the projection of the first support member 41 and the second support member 42 along the width direction of the drawer does not exceed half of their respective areas, thereby facilitating the provision of installation space for the first and second supports.

[0098] The first support member 41 and the second support member 42 have a gap along the depth direction of the drawer, thereby reducing the risk of interference when installing the first support member and the second support member.

[0099] The projections of the first support member 41 and the second support member 42 along the depth direction of the drawer do not overlap. Specifically, the side of the first support member 41 facing the drawer 2 protrudes more than the side of the second support member 42 facing the drawer 2. The second support member 42 may be higher than the first support member 41, or the first support member 41 and the second support member 42 may be flush in height. In one embodiment of this application, the second support member 42 is higher than the first support member 41. Thus, when the first support member 41 and the second support member 42 are installed on the guide rail assembly in an alternating arrangement along the depth direction of the drawer, the first support member and the second support member will not interfere with each other.

[0100] In order to cooperate with the first support member 41 and the second support member 42, the slide rail assembly 3 includes a support surface 6, namely the first support surface 31, which cooperates with the first support member 41, and a second support surface 32, which is different from the support surface 31 and cooperates with the second support member 42.

[0101] like Figure 7 As shown, the first support surface 31 and the second support surface 32 are located on the same support rib of the slide rail assembly 3. The first support surface 31 and the second support surface 32 are configured to move within the slide rail 46 of the guide rail assembly 4. In other embodiments, the first support surface 31 and the second support surface 32 may not be on the same support rib.

[0102] The distance that the second support surface 32 extends away from the drawer 2 is greater than the distance that the first support surface 31 extends away from the drawer 2, so that the first support surface 31 abuts against the first support member 41 and the second support surface 32 abuts against the second support member 42.

[0103] Specifically, the first support surface 31 includes a first front support surface 311, a first rear support surface 312, and a first stop groove 313 connecting the first front support surface 311 and the first rear support surface 312. The second support surface 32 includes a second front support surface 321, a second rear support surface 322, and a second stop groove 323 connecting the second front support surface 321 and the second rear support surface 322. The length of the second rear support surface 322 is greater than the length of the first rear support surface 312.

[0104] like Figures 9A to 9C As shown, in Figure 9A The "front" and "back" markings refer to the direction of movement towards the user when operating the drawer, which is considered the front and the direction away from the user, which is considered the back.

[0105] When installing the drawer, the drawer 2 is tilted so that the rollers 25 enter the front side of the slide rail 46 from the slide rail opening 461 behind the second support member 42. Then the drawer 2 is rotated to a near-horizontal position so that the support rib forming the first support surface 31 is inserted between the first support member 41 and the second support member 42 to install the drawer on the guide rail assembly 4.

[0106] When drawer 2 is pulled out of storage compartment 11, the first front support surface 311 engages with the first support member 41, and the second front support surface 321 engages with the second support member 42, allowing drawer 2 to move smoothly within storage compartment 11. When drawer 2 is pulled out to a certain position, the first stop groove 313 abuts against the first support member 41, and the second stop groove 323 abuts against the second support member 42, thereby limiting drawer 2 to its current open position. Compared to the prior art, which uses only one stop groove to engage with the support member to limit the open position of drawer 2, the present application's technical solution uses two stop grooves to engage with the guide rail assembly to limit the drawer to a preset position, improving the guide rail assembly's load-bearing capacity for the drawer.

[0107] When drawer 2 is pulled out of storage compartment 11, after the first rear support surface 312 disengages from the first support member 41, the roller 25 has not yet reached the slide opening 461. At this time, the drawer cannot be taken out of storage compartment. Therefore, the longer second rear support surface 322 cooperates with the second support member 42 to continue supporting the movement of drawer 2 in storage compartment 11 until the roller of drawer 2 disengages from the slide 46 of guide rail assembly 4, at which point the drawer can be completely taken out of storage compartment.

[0108] Example 3

[0109] In the embodiments of this application, such as Figures 10 to 13 As shown, the guide rail assembly 4 is provided with a first support member 41 and a second support member 42. The first support member 41 and the second support member 42 are located in front of the guide rail assembly 4. The first support member 41 is located above the second support member 42. The side of the second support member 42 facing the drawer protrudes from the side of the first support member 41 facing the drawer 2. Preferably, the first support member 41 is located directly above the second support member 42.

[0110] The slide rail assembly 3 is configured as a support rib extending away from the drawer 2. The slide rail assembly has a support surface 6, namely a first support surface 31, which cooperates with the first support member 41 to support the drawer. Additionally, a second support member 42 cooperates with another support surface of the drawer. In one specific embodiment, the second support member 42 cooperates with the bottom wall 21 of the drawer 2. The bottom wall 21 has a second support surface 32, which is different from the first support surface 31, and the second support surface 32 is parallel to the first support surface 31. In the embodiments of this application, while ensuring that the second support member 42 cooperates with the bottom wall 21 of the drawer 2, it is positioned as close as possible to the side wall 24 of the adjacent drawer 2.

[0111] Example 4

[0112] To improve the load-bearing strength of the guide rail assembly 4, a reinforcing member 5 is provided on the guide rail assembly 4. The reinforcing member 5 is connected to the guide rail assembly 4 from the side away from the drawer 2, and the reinforcing member 5 is at least connected to the first support member 41. Specifically, the reinforcing member is a metal part.

[0113] Specifically, such as Figures 14 to 18 As shown, the reinforcing member 5 includes a first mounting portion 51. The first mounting portion 51 is configured as a U-shaped structure with the opening facing upwards. Specifically, the first mounting portion 51 includes a first mounting plate 511 and a second mounting plate 512 spaced apart, and a connecting plate 513 connecting the first mounting plate 511 and the second mounting plate 512. The first mounting plate 511 and the second mounting plate 512 extend in a direction parallel to the height of the drawer. The first mounting plate 511, the second mounting plate 512, and the connecting plate 513 form a U-shaped structure with the opening facing upwards.

[0114] The distance between the first mounting plate 511 and the second mounting plate 512 is at least three times the thickness of the first mounting plate 511 or the thickness of the second mounting plate 512.

[0115] like Figure 16 As shown, one end of the connecting plate 513 is smoothly and continuously connected to the first mounting plate 511 through a rounded corner edge 5131, the radius of which is greater than or equal to the thickness of the first mounting plate 511. Similarly, the other end of the connecting plate 513 is smoothly and continuously connected to the second mounting plate 512 through a rounded corner edge 5131, the radius of which is greater than or equal to the thickness of the second mounting plate 512.

[0116] like Figure 15 As shown, the first support member 41 is provided with a fastening part 411, which is adapted to connect with the first mounting plate 511 and the second mounting plate 512. Thus, the first support member is fixedly supported by the two mounting plates, thereby improving the drawer's load-bearing capacity of the guide rail assembly.

[0117] The first mounting plate 511 is provided with a first mounting hole 5111, and the second mounting plate 512 is provided with a second mounting hole 5121. The center line of the first mounting hole 5111 and the center line of the second mounting hole 5121 are on the same horizontal straight line, which facilitates the assembly of the first support member and the reinforcing member.

[0118] The guide rail assembly 4 is provided with a first fixing hole 47 opposite to the first mounting hole 5111, thereby the fastening part 411 passes through the first fixing hole 47 and connects with the first mounting hole 5111 and the second mounting hole 5121.

[0119] In the embodiments of this application, such as Figure 17 As shown, the shape of the first fixing hole 47 is adapted to the shape of the first mounting plate 511 of the first mounting part 51. Specifically, the first mounting plate 511 is adapted to enter the first fixing hole 47 so as to at least partially close the opening area of ​​the first fixing hole 47.

[0120] like Figure 15 As shown, an elastic element 412 is provided between the first support member 41 and the first mounting portion 511. The elastic element 412 completely abuts against the first mounting portion 511. Therefore, when the guide rail assembly 4 is made of plastic and the reinforcing member 5 is made of metal, during the installation of the first support member 41, the elastic element is prevented from contacting the plastic guide rail assembly, thus preventing damage to the plastic guide rail assembly. The elastic element 412 only abuts against the first mounting plate 511, so the installation force applied to the first support member only acts on the reinforcing member. In the embodiments of this application, the elastic element is a rubber washer; in other embodiments, the elastic element can be a spring, a spring-like metal piece, or other elastic material.

[0121] The projection of the first support member along the width of the drawer completely covers the projection of the first mounting plate along the width of the drawer. Thus, when viewed from the side of the first support member, the guide rail assembly is shown to have the reinforcing member concealed by the first support member, thereby improving the aesthetics of the guide rail assembly.

[0122] The side of the first mounting part 51 near the drawer 2 is coplanar with the side of the guide rail assembly 4 that defines the first fixing hole 47 facing the drawer. Specifically, the side of the first mounting plate 511 facing the drawer is coplanar with the side of the first fixing hole 47 facing the drawer. This ensures that an appropriate gap is maintained between the first support member and the guide rail assembly, thereby preventing interference between the first support member and the guide rail assembly.

[0123] The reinforcing member 5 also includes a second mounting portion 52. The second mounting portion 52 is connected to the slide rail 46 of the guide rail assembly 4. The second mounting portion is L-shaped; specifically, the second mounting portion 52 includes a third mounting plate 523 extending parallel to the height direction of the drawer and a flange 522 connected to the third mounting plate 523. The flange 522 extends parallel to the width direction of the drawer and toward the drawer. The flange 522 and the third mounting plate 523 are smoothly and continuously connected together by rounded corner edges. In other embodiments, the second mounting portion may be configured as a mounting plate extending parallel to the height direction of the guide rail assembly.

[0124] The third mounting plate 523 is provided with a third mounting hole 521, and the guide rail assembly 4 is provided with a second fixing hole 48 opposite to the third mounting hole 521. The second fixing hole 48 is located at the slide 46 of the guide rail assembly 4 and is located above the first fixing hole 47. The fastener passes through the second fixing hole 48 and the third mounting hole 521 and is connected to the housing 1.

[0125] The first mounting part 51 and the second mounting part 52 are integrally formed. Specifically, a connecting plate 53 is provided between the first mounting part 51 and the second mounting part 52. One end of the connecting plate 53 is connected to the first mounting part 51, and the other end is connected to the second mounting part 52. The folded edge 53 is smoothly and continuously connected to the first mounting part 51 and the second mounting part 52 through the rounded corner edge.

[0126] In the embodiments of this application, the second mounting part 52 is closer to the inner wall 12 of the housing 1 than the first mounting part 51.

[0127] like Figure 18 As shown, the guide rail assembly 4 is provided with a receiving cavity 49 for mounting the reinforcing member 5. The receiving cavity 49 is provided with a limiting rib 45, and the reinforcing member 5 is adapted to be supported on the limiting rib 45.

[0128] In one embodiment of this application, two first limiting ribs 451 are provided in the accommodating cavity 49, which are arranged at a relatively distance from each other. The distance between the two first limiting ribs 451 does not exceed the length of the flange 522. The first limiting ribs 451 are provided with slots 4511 for engaging the first mounting part 51. A second limiting rib 452 is provided below the first limiting ribs. The second limiting rib 452 is used to support the bottom end of the first mounting part 51.

[0129] Specifically, when installing the reinforcing member, the flange 522 of the second mounting part 52 overlaps the upper end of the first limiting rib 451, the first mounting part 51 is inserted into the groove 4511, and the lower end of the first mounting part 51 is supported on the second limiting rib 452.

[0130] The first fixing hole 47 and the second fixing hole 48 are located inside the receiving cavity 49, with the second fixing hole 48 located above the first fixing hole 47. The receiving cavity 9 has a protrusion 453 extending from the slide rail 46 of the guide rail assembly 4 toward the housing 1, and the second fixing hole 48 is disposed on this protrusion 453.

[0131] In the embodiments of this application, the fastening part 411 is machine-taped threaded, and correspondingly, the first mounting hole 5111 and the second mounting hole 5121 connected to the fastening part 411 are machined with threads.

[0132] This application has been described with reference to the above-mentioned embodiments; however, the above embodiments are merely examples for implementing this application. It must be noted that the disclosed embodiments do not limit the scope of this application. On the contrary, any modifications and refinements made without departing from the spirit and scope of this application are within the scope of patent protection of this application.
