Description

Technical Field

[0001] This application relates to the technical field of refrigerators, and particularly to a refrigerator. Background Art

[0002] A drawer is slidably installed in the inner liner of a refrigerator to achieve pulling and opening. A common form of sliding fit between the drawer and the inner liner of the refrigerator is to provide an injection molding slideway on the side wall of the drawer, and a chute is opened on the inner liner of the refrigerator. The injection molding slideway and the chute are slidably mated to achieve the pulling movement of the drawer relative to the inner liner of the refrigerator. Generally, the injection molding slideway does not exceed the length of the drawer, because if the injection molding slideway extends beyond the drawer, it will interfere with structures such as the air duct in the inner liner of the refrigerator. That is, limited by the length of the injection molding slideway, the drawer cannot be completely pulled out from the inner liner of the refrigerator, thus making it inconvenient for users to take and place items in the drawer. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a refrigerator that can increase the stretching stroke of the drawer to facilitate users to take and place items in the drawer.

[0004] A refrigerator includes an inner liner of the refrigerator, a pulling device, and a drawer. The pulling device includes a first support member, a second support member, and a sliding connecting member. The first support member is fixedly connected to the inner liner of the refrigerator, the second support member is fixedly connected to the drawer, one side of the sliding connecting member is slidably connected to the first support member along a preset direction X, and the other side of the sliding connecting member is slidably connected to the second support member along the preset direction X; the pulling device has a contracted state and an extended state. When the pulling device is in the contracted state, the pulling device does not protrude from the drawer along the preset direction X. When the pulling device is in the extended state, the drawer can be completely extended out of the inner liner of the refrigerator.

[0005] In one embodiment, along the preset direction X, the length of the drawer is equal to the elongation stroke of the pulling device when switching from the contracted state to the extended state.

[0006] In one embodiment, the sliding connecting member is provided with two sets of roller groups spaced along its height direction. Each set of roller groups includes at least one roller. The first support member has an upper edge and a lower edge distributed along its height direction; the upper edge and the lower edge are respectively slidably mated with a corresponding set of roller groups along the preset direction X.

[0007] In one embodiment, the roller has a V-shaped groove, the upper edge and the lower edge are both wedge-shaped, and the upper edge and the lower edge are respectively slidably clamped in the corresponding V-shaped grooves.

[0008] In one embodiment, the two sets of roller groups are symmetrically arranged in the height direction of the sliding connecting member, and each set of roller groups includes two rollers spaced along the preset direction X.

[0009] In one embodiment, one of the first support member and the sliding connection member is provided with a first limiting block and a second limiting block, and the other is provided with a third limiting block; the first limiting block and the second limiting block are spaced apart along a preset direction X, and the third limiting block is slidably disposed between the first limiting block and the second limiting block.

[0010] In one embodiment, a through groove is formed in the side surface of the first support member facing the sliding connection member, the through groove extends along the preset direction X, and the first limiting block and the second limiting block are disposed in the through groove.

[0011] In one embodiment, the second support member includes a mounting base and a slider disposed on the mounting base, the mounting base is used for fixedly mounting to the side wall of the drawer, and the slider is slidably connected to the sliding connection member along the preset direction X.

[0012] In one embodiment, the slider is provided with an upward flanging and a downward flanging distributed in its own height direction, the sliding connection member is provided with a rib extending along the preset direction X, and the slider is slidably sleeved on the outer periphery of the rib through the upward flanging and the downward flanging.

[0013] In one embodiment, along the height direction of the rib, a first groove is formed at the top end of the rib, a second groove is formed at the bottom end of the rib, the upward flanging is slidably clamped in the first groove, and the downward flanging is slidably clamped in the second groove.

[0014] Compared with the prior art, the refrigerator provided by the present application enables the pulling device to expand and contract along the preset direction X by arranging the first support member, the second support member and the sliding connection member. The pulling device in the contracted state is not convex out of the drawer along the preset direction X in the inner liner of the refrigerator. Therefore, the pulling device will not interfere with structures such as the air duct in the inner liner of the refrigerator. By the relative sliding of the first support member, the second support member and the sliding connection member, the pulling device extends along the preset direction X to switch to the extended state, so as to increase the stretching stroke of the drawer, so that the drawer can completely extend out of the inner liner of the refrigerator, facilitating the user to take and place items from the drawer.

[0029] Please refer to Figure 1 and Figure 2 , this application provides a refrigerator, which includes an inner box liner, a pulling device 100 and a drawer 200. The pulling device 100 includes a first support member 10, a second support member 20 and a sliding connecting member 30. The first support member 10 is fixedly connected to the inner box liner, the second support member 20 is fixedly connected to the drawer 200, one side of the sliding connecting member 30 is slidably connected to the first support member 10 along a preset direction X, and the other side of the sliding connecting member 30 is slidably connected to the second support member 20 along the preset direction X. The pulling device 100 has a contracted state and an extended state. When the pulling device 100 is in the contracted state, the pulling device 100 does not protrude from the drawer 200 along the preset direction X. When the pulling device 100 is in the extended state, the drawer 200 can be fully extended out of the inner box liner.

[0030] It should be noted that the preset direction X refers to the pulling direction of the drawer 200 relative to the inner liner of the box, specifically the length direction of the drawer 200. By providing the first support member 10, the second support member 20, and the sliding connection member 30, the pulling device 100 can be telescoped along the preset direction X. When the pulling device 100 is in the retracted state, it does not protrude from the drawer 200 along the preset direction X within the inner liner of the box. Therefore, the pulling device 100 will not interfere with structures such as the air duct in the inner liner of the box. By the relative sliding of the first support member 10, the second support member 20, and the sliding connection member 30, the pulling device 100 extends along the preset direction X to switch to the extended state, thereby increasing the pulling stroke of the drawer 200 and enabling the drawer 200 to fully extend out of the inner liner of the box for the convenience of the user to take and place items in the drawer 200.

[0031] Specifically, the first support member 10, the second support member 20, and the sliding connection member 30 are all in the shape of plates, and when the pulling device 100 is in the retracted state, the first support member 10, the second support member 20, and the sliding connection member 30 are stacked along the thickness direction; by pulling the drawer 200 along the preset direction X, the first support member 10, the second support member 20, and the sliding connection member 30 slide relative to each other until they are end-to-end along the preset direction X.

[0032] Among them, the first support member 10 can be fixedly connected to the inner liner of the box by screws, and the second support member 20 can also be fixedly connected to the drawer 200 by screws.

[0033] Exemplarily, in one embodiment, along the preset direction X, the length of the drawer 200 is equal to the extension stroke of the pulling device 100 when switching from the retracted state to the extended state. In other words, the pulling device 100 can extend by the length of a drawer 200 when switching from the retracted state to the extended state, so that the drawer 200 can just fully extend out of the inner liner of the box. Of course, in other embodiments, along the preset direction X, the length of the drawer 200 can also be greater than the extension stroke of the pulling device 100 when switching from the retracted state to the extended state.

[0034] Among them, the extension stroke of the pulling device 100 when switching from the retracted state to the extended state is equal to the sum of the sliding stroke between the first support member 10 and the sliding connection member 30 and the sliding stroke between the second support member 20 and the sliding connection member 30.

[0035] Please refer to Figures 1 to 5, the sliding connector 30 is provided with two sets of roller groups 301 spaced apart along its height direction, and each set of roller groups 301 includes at least one roller 31. The first support member 10 has an upper edge 11 and a lower edge 12 distributed along its height direction; the upper edge 11 and the lower edge 12 are respectively in sliding fit with a corresponding set of roller groups 301 along the preset direction X. That is to say, the first support member 10 is slidably clamped between the two sets of roller groups 301. When a certain roller 31 in the roller group 301 is damaged, it will not affect the normal operation of other rollers 31, and only the damaged roller 31 needs to be replaced, which is beneficial to cost savings.

[0036] Further, as Figure 4 and Figure 7 shown, the roller 31 has a V-shaped groove 311, the upper edge 11 and the lower edge 12 are both wedge-shaped, and the upper edge 11 and the lower edge 12 are respectively slidably clamped in the corresponding V-shaped grooves 311. In this way, while ensuring the firm clamping of the roller 31 and the first support member 10, the V-shaped groove 311 cooperates with the wedge-shaped upper edge 11 or lower edge 12 to provide precise linear motion guidance, so that the first support member 10 and the sliding connector 30 can perform relative sliding more precisely and stably.

[0037] Exemplarily, in an embodiment, the two sets of roller groups 301 are symmetrically arranged in the height direction of the sliding connector 30, and each set of roller groups 301 includes two rollers 31 spaced apart along the preset direction X. In this way, the upper edge 11 and the lower edge 12 are more evenly stressed.

[0038] Please refer to Figures 1 to 5 , one of the first support member 10 and the sliding connector 30 is provided with a first limit block 13 and a second limit block 14, and the other is provided with a third limit block 32; the first limit block 13 and the second limit block 14 are spaced apart along the preset direction X, and the third limit block 32 is slidably installed between the first limit block 13 and the second limit block 14. In other words, the first limit block 13 and the second limit block 14 can be provided on the first support member 10, and the third limit block 32 can be provided on the sliding connector 30; or, the first limit block 13 and the second limit block 14 can be provided on the sliding connector 30, and the third limit block 32 can be provided on the first support member 10. The third limit block 32 slides between the first limit block 13 and the second limit block 14, thereby defining the sliding stroke of the first support member 10 and the sliding connector 30 in the preset direction X.

[0039] Exemplarily, in one embodiment, the first limiting block 13 and the second limiting block 14 are arranged on the first support member 10, and the third limiting block 32 is arranged on the sliding connecting member 30. When the drawing device 100 is in a contracted state, the third limiting block 32 abuts against the first limiting block 13, and when the drawing device 100 is in an extended state, the third limiting block 32 abuts against the second limiting block 14.

[0040] Further, as Figure 4 shown, a through groove 15 is formed in the side surface of the first support member 10 facing the sliding connecting member 30. The through groove 15 extends along a preset direction X, and the first limiting block 13 and the second limiting block 14 are arranged in the through groove 15. The through groove 15 guides the sliding of the third limiting block 32 between the first limiting block 13 and the second limiting block 14.

[0041] As Figure 3 shown, the second support member 20 includes a mounting base 21 and a slider 23 arranged on the mounting base 21. The mounting base 21 is used for fixedly mounting to the side wall of the drawer 200, and the slider 23 is slidably connected to the sliding connecting member 30 along the preset direction X. The mounting base 21 is used to increase the connection area with the side wall of the drawer 200, so that the second support member 20 is more firmly fixed to the drawer 200.

[0042] Exemplarily, the mounting base 21 is in the shape of a rectangular plate, and the four corners of the rectangular plate-shaped mounting base 21 are respectively connected to the side wall of the drawer 200 by screws.

[0043] Please refer to Figures 3 to 7 , the slider 23 has an upper flanging 231 and a lower flanging 232 distributed along its own height direction. The sliding connecting member 30 is provided with a rib 33 extending along the preset direction X. The slider 23 is slidably sleeved on the outer periphery of the rib 33 through the upper flanging 231 and the lower flanging 232.

[0044] Further, along the height direction of the rib 33, a first groove 331 is formed at the top end of the rib 33, and a second groove 332 is formed at the bottom end of the rib 33. The upper flanging 231 is slidably clamped in the first groove 331, and the lower flanging 232 is slidably clamped in the second groove 332. Specifically, the cross section of the slider 23 is approximately C-shaped. The groove wall of the first groove 331 limits the upper flanging 231, and the groove wall of the second groove 332 limits the lower flanging 232, so as to prevent the slider 23 from disengaging from the rib 33.

[0045] Specifically, taking the cooperation process between the upward flanging 231 and the first groove 331 as an example, the limiting effect of the first groove 331 on the upward flanging 231 is introduced. The upward flanging 231 slides between the front wall and the rear wall of the first groove 331 along the preset direction X to define the relative sliding stroke between the second support member 20 and the sliding connection member 30. The upward flanging 231 abuts against the side wall of the first groove 331 along the thickness direction of the rib 33 to prevent the second support member 20 from detaching from the sliding connection member 30.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0047] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
