Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a door structure and a refrigerator. Background Art

[0002] As people's quality of life gradually improves, the trend toward integrated kitchen appliances is becoming increasingly evident, leading to a growing demand for built-in refrigerators. Traditional refrigerators, due to the hinged structure of the door and refrigerator cabinet, protrude from the side wall when the door is opened. This is done in ample space, without affecting user usability. However, built-in refrigerators, however, are limited by cabinet space. To ensure the door opens effectively, the corners must not protrude significantly beyond the cabinet dimensions.

[0003] To meet the needs of embedded refrigerators, the existing published patent CN118057103A provides an embedded hinge assembly and refrigerator. It uses a six-link hinge, which is staggered through specific hinge points and connecting rods of different shapes to achieve a specific movement trajectory for the door. This embedded hinge is relatively expensive, has a single function, and takes up a large amount of space in the refrigerator. During the opening and closing of the door, the hinge seat has a small force arm for rotation, resulting in a large thrust required to rotate the refrigerator door, which is inconvenient to operate. This hinge has many internal connection base points, some of which are not fixed and move with the door, making it easy for the door to open and close smoothly. Utility Model Content

[0004] In order to solve the technical problem of the prior art that the embedded refrigerator body adopts a complex hinge structure, the utility model provides a door structure and a refrigerator.

[0022] When the door body is in a closed state, the sliding pin is stuck in the first locking position of the buckle. During the opening process of the door body, the buckle moves with the second slide rail, and the sliding pin disengages from the first locking position and slides into the second locking position, so that the fixed pin shaft drives the spring fixed cover to move toward the other end of the slide rail seat to push the first slide rail to slide. After the sliding pin disengages from the second locking position, it stops pushing the first slide rail, and the second slide rail can continue to slide along the first slide rail.

[0023] Furthermore, a buffer component is provided at the end of the first slide rail, and a blocking piece is provided on the inner side surface of the second slide rail. When the blocking piece contacts the buffer component, the door body opens to the maximum position.

[0027] Hinge assemblies are respectively provided at the top and bottom of the box body near the front side, and the hinge assemblies fix the two ends of the mounting column.

[0028] The utility model also provides a refrigerator, comprising the above-mentioned embedded door structure.

[0029] Compared with the existing technology, the utility model redesigns the refrigerator door and the door mounting column structure, so that when the refrigerator door is opened, the turning radius moves inward, and the extent to which the refrigerator door protrudes from the refrigerator body when opened is controlled. The fixed design of the door mounting column ensures that the door will not hit the cabinet wall during the opening process. It is easy to install, opens smoothly, and has high stability.

[0030] The display assembly is fixed to the door mounting post, eliminating the need for a separate embedded box, simplifying installation and reducing costs. The door communication wiring harness is routed through the mounting post and the square hole between the upper hinge, shortening the wiring harness length. The fixed upper hinge ensures stable wiring, eliminating the risk of wiring harness falling or wearing out due to door opening. Positioning the display assembly on the right side of the door facilitates user operation, improving human-computer interaction, and enhancing the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0069] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0070] Existing patent CN118057103A provides an embedded hinge assembly and refrigerator, comprising: a cabinet mounting base, a door connecting base, a first connecting rod, a second connecting rod, and a third connecting rod. The first connecting rod has one end rotatably and slidingly connected to the cabinet mounting base and the other end rotatably connected to the door connecting base. The second connecting rod is staggered with the first connecting rod, and the two are rotatably connected at the intersection point. One end of the second connecting rod is rotatably connected to the cabinet mounting base. The third connecting rod has one end rotatably connected to the other end of the second connecting rod and the other end rotatably connected to the door connecting base.

[0071] The hinge assembly provided by the embodiment of the present invention is adopted, by setting one end of the first link to be connected to the box mounting seat for rotation and sliding, and the second link and the first link are rotatably staggered. During the expansion of the hinge, one end of the first link slides, which can cause the other end of the first link to move accordingly. When the other end of the first link is connected to the door body, the door body can be driven away from the box body. When used in a built-in refrigerator, it can effectively prevent the door body from colliding with obstacles in the cabinet. Compared with the existing six-link hinge method, the use of this hinge assembly can reduce at least one link and two hinge points, directly reduce the number of links and reduce the thickness of the staggered stacking between the links, which can most directly and fundamentally solve the problem of hinge thickness.

[0072] The aforementioned embedded hinges are expensive, limited in use, and occupy a large space in the refrigerator. During door opening and closing, the hinge base has a small lever arm, resulting in a large thrust required to rotate the refrigerator door, making operation inconvenient. These hinges also have numerous internal connection points, some of which are not fixed and move with the door, making it prone to opening and closing problems.

[0073] In this regard, Figure 1 、 2 As shown, the utility model proposes an embedded door structure, which is mainly used in embedded refrigerators, including: a box body 1 and a door body 2 installed on the front of the box body 1, a mounting column 3 is vertically arranged near the side of the box body front 13, the mounting column 3 protrudes from the box body front 13, and the side of the mounting column 3 for mounting the door body is an arc surface, and a slide rail assembly 5 with an overall arc shape is installed on the arc surface, and at the same time, the right side of the door body 2 corresponding to the position of the mounting column 3 is concave to form a vertical groove, so that the mounting column can be stuck in the groove, and at the same time, the inner wall of the groove of the door body 2 is connected to the slide rail on the slide rail assembly 5, so that the door body rotates around the mounting column through the slide rail during rotation.

[0074] The present invention provides a groove on the rotating side of the door body, and simultaneously provides a mounting post on the side of the front of the box body, and a slide rail assembly on the mounting post. This allows the door body to give way through the groove during the rotation of the slide rail. Even when the door body is rotated to the maximum opening, it will not contact the cabinet or box body outside the box body, achieving an embedded effect. In addition, the use of mounting posts and slide rails simplifies the movement trajectory of the door body, is less likely to cause quality problems, and reduces the manufacturing cost of the mechanical structure.

[0075] like Figure 14 、 15 As shown in Figures 16, in a specific embodiment, an arc-shaped groove 21 is provided on the inner wall surface of the groove of the door body 2. After the door body 2 is connected to the slide rail of the slide rail assembly 5 on the mounting column 3, the mounting column 3 is located in the groove of the door body, and at the same time, the slide rail assembly 5 is located in the arc-shaped groove 21 formed by the concave inner wall surface of the groove, and the slide rail is specifically connected to the inner wall surface of the arc-shaped groove.

[0076] In other embodiments, an arcuate groove for mounting the slide rail assembly may also be provided on the arcuate mounting surface of the mounting post, so that the slide rail assembly can be embedded in the arcuate mounting surface of the mounting post.

[0077] In addition, the groove on the door body 2 is located at the side edge of the front of the door body, which prevents the door body from exceeding the side of the box body when it is opened to be perpendicular to the front of the box body.

[0078] By setting the groove, the gap between the door body and the installation column can be maintained during rotation, so that the door body can rotate normally. At the same time, setting the groove can eliminate the side corners of the door body, preventing the side corners from colliding with the cabinet during the rotation of the door body or when it is rotated to the maximum angle.

[0079] like Figure 5 、 6 As shown in Figures 7 and 8, in a specific embodiment, the slide rail assembly 5 includes: a slide rail seat 51, a first slide rail 52 and a second slide rail 53. The slide rail seat 51 is installed on the arc side of the mounting column 3, and the back of the slide rail seat 51 is fixedly connected to the arc side of the mounting column 3. Square curling edges are provided on the upper and lower sides of the front to form a first slide groove surrounding the arc side of the mounting column. The first slide rail 52 is installed in the first slide groove on the front of the slide rail seat 51, and the upper and lower sides of the first slide rail 52 are arc-shaped curling edges that cooperate with the square curling edges of the slide rail seat 51, and a second slide groove is formed between the arc curling edges on the upper and lower sides for sliding; the second slide rail 53 is installed in the second slide groove on the front of the first slide rail 52 and can slide along the second slide groove, and the front of the second slide rail 53 is fixedly connected to the door body 2. Due to the thickness limitation of the door body 2, the length of the arc track of the arc side of the mounting column is limited. By setting two sliding rails, the rotational stroke of the door body is increased, so that the door body can not only be rotated from a closed state to a state perpendicular to the front of the box body, but can also be further opened.

[0080] Specifically, the slide rail assembly 5 also includes: a spring component and a pin component. The spring component is installed in the first slide groove of the slide rail seat near one end, and is used to push the first slide rail to slide toward the other end of the first slide groove. After moving a certain distance, it is automatically reset by the spring; the pin component is driven by the second slide rail when it slides, and when it is driven, it pushes the first slide rail to slide, so that the first slide rail and the second slide rail move together for a certain distance.

[0081] That is, by adding the spring component and the pin component, the first slide rail and the second slide rail can move together for a certain distance, thereby ensuring that the first slide rail and the second slide rail can slide reliably.

[0082] The spring assembly includes a spring retainer 55, a spring 59, and a spring retainer cover 58. The spring retainer 55 is mounted at one end within the slide rail seat 51. The spring 59 is mounted on the side of the spring retainer 55 facing the other end of the slide rail seat 51. Specifically, spring mounting locations are provided at the upper and lower portions of the side for connecting the ends of the spring 59. A fixing plate is provided in the middle of the side, and a guide groove is provided on the fixing plate along the sliding direction of the slide rail seat. One end of the two springs is connected to the spring mounting location of the spring retainer 55. The spring retainer cover 58 is also mounted within the first slide groove of the slide rail seat 51 and covers the spring 59. The inner side of the spring retainer cover 58 is provided with a covering groove corresponding to the spring 59. The covering groove is open at one end and closed at the other end with a push plate fold. The spring 59 extends into the other end of the covering groove and is fixedly connected to the closed end of the covering groove. When the spring fixing cover 58 moves toward the other end of the slide rail seat 51 , the spring 59 is stretched, and its push plate pushes the first slide rail 52 to slide along the slide rail seat 51 toward the other end of the slide rail seat 51 .

[0083] The spring of the spring component is covered inside to avoid affecting the expansion and contraction of the spring during the sliding process, thereby avoiding mechanical failure. In addition, adding a spring component in the slide rail can make the door opening and closing smoother and avoid the slide rail from getting stuck.

[0084] Specifically, the pin shaft component includes: a fixed pin shaft 56 and a buckle 57. Pins are provided on both sides of the fixed pin shaft 56, with its front side facing the second slide rail 53 and its back side facing the slide rail seat 51. The back side is respectively provided with a guide pin that can slide along the guide groove, and a latch 562 that is buckled on the spring fixing cover (the middle part of the spring fixing cover is provided with a flange, which is clamped between the latch and the guide pin), and a sliding pin 561 is provided on the front side; the buckle 57 is installed on the inner side surface of the second slide rail 53 (the inner side surface is the side facing away from the door body groove), and a first latch position 572 and a second latch position 573 are provided on the buckle 57;

[0085] When the door body is in a closed state, the sliding pin 561 is stuck in the first position 572 of the buckle 57. During the opening process of the door body 2, the buckle 57 moves with the second slide rail 53, and the sliding pin 561 disengages from the first position 572 and slides into the second position 573. During this process, the fixed pin shaft 56 does not move. After the sliding pin 561 slides into the second position 573, if the second slide rail 53 continues to be driven by the door body 2, the fixed pin shaft 56 drives the spring fixing cover 58 to move toward the other end of the slide rail seat 51 to push the first slide rail 52 to slide. After the sliding pin 561 disengages from the second position 573, it stops pushing the first slide rail 52, and the spring 59 contracts to drive the spring fixing cover 58 to return to its position, and the second slide rail 53 can continue to slide along the first slide rail 52 for a stroke.

[0086] That is, the first slide rail and the second slide rail are driven to move in coordination through the pin shaft and the buckle, so that the first slide rail and the second slide rail can move together for a stroke, and the second slide rail can move alone for two strokes.

[0087] Specifically, a buffer component is provided at the end of the first slide rail 52, specifically, a card 521 is set at the inner end of the second slide groove of the first slide rail, and a buffer plug 54 (specifically, a flexible material can be used) is sleeved on the card 521. At the same time, a baffle 533 is provided on the inner side of the second slide rail 53. When the second slide rail 53 slides on the first slide rail 52 until the baffle on its inner side hits the buffer component, the door body 2 opens to the maximum position.

[0088] By setting up buffer components and baffles, the maximum opening position of the door body is limited to prevent the door body from exceeding the side of the box body. At the same time, buffering is set to avoid direct impact on the slide rail and affect the service life of the slide rail assembly.

[0089] In a specific embodiment, the various fixed connection locations of the slide rail assembly can be connected using screws. Specifically, a first fixing hole 511 is provided in the middle of the slide rail base 51, allowing the slide rail base 51 to be fixed to the column mounting hole 313 of the mounting column by screws passing through the first fixing hole 511. Furthermore, a second fixing hole 512 is provided in the middle of the slide rail base 51, and a third fixing hole 551 is provided in the spring fixing base 55. The spring fixing base 55 can be fixed by screws passing through the third fixing hole 551 and the second fixing hole 512. The buckle 57 has a fourth fixing hole 571, and the second slide rail 53 has a corresponding fifth fixing hole 531, so that the buckle 57 can be fixed to the second slide rail 53 using screws.

[0090] In a specific embodiment, the second slide rail of the slide rail assembly is connected to the door body by snap-fitting. Since it is difficult to install the door body and the slide rail with screws, snap-fitting is used for easy assembly.

[0091] Specifically, a bayonet 532 is provided on the second slide rail 53, and a block 22 corresponding to the bayonet is provided in the groove of the door body 2 (specifically, in the arc groove located on the inner wall of the groove); or a block is provided on the second slide rail, and a bayonet corresponding to the block is provided in the groove of the door body.

[0092] In a specific embodiment, the mounting column has three side surfaces, the front side surface and the right side surface are flat, the rear side surface and the left side surface are arc surfaces with smooth transitions, and the front side surface (i.e., the front) is provided with a mounting groove, which is used to install the display component of the refrigerator, and the door communication harness of the display component is connected to the display component through the inside of the mounting column.

[0093] like Figure 3 、 4 As shown in Figures 13 and 14, the mounting column specifically includes: a tubular column 31, an upper cover 32 and a lower cover 33 mounted at both ends of the column 31. The ends of the column 31 are provided with sockets near the tube wall, and the covers are provided with inserts at positions corresponding to the sockets, allowing the covers to be stably mounted on both ends of the column. Both the upper and lower covers are provided with hinge shaft mounting holes 321. The hinge shaft mounting hole 321 of the upper cover is used to insert the hinge shaft and the door communication harness 7 that passes through the display assembly 6.

[0094] By placing the display assembly directly on the mounting post, compared to the existing method of placing it on the door, complex wiring can be avoided and the wiring harness length can be shortened. Furthermore, because the mounting post is fixed to the cabinet, the wiring harness routing is stable, eliminating the problem of the door harness falling off or wearing out due to door opening. Placing the display assembly on the right side of the door facilitates user operation, improves human-computer interaction, and enhances the user experience.

[0095] In a specific embodiment, the side surface of the mounting post 3 for mounting the slide rail assembly 5 is arc-shaped, and the groove on the side surface of the door body 2 is an arc-shaped groove, so that the door body 2 can rotate around the mounting post normally while retaining clearance.

[0096] like Figure 14 、 15 As shown, in a specific embodiment, hinge assemblies 4 are provided at the top and bottom of the box body near the front side, and the hinge assemblies fix the two ends of the mounting column.

[0097] By securing the mounting post from both ends, structural strength is increased while facilitating wiring harness routing.

[0098] like Figure 14 、 15As shown, the hinge assembly 4 specifically includes an upper hinge 41 located at the top of the box and a lower hinge 42 located at the bottom of the box. A portion of the upper hinge 41 is fixed to the top of the box, while the other portion extends from the top surface of the box to the front surface of the box. A square hinge shaft 411 is provided on this portion. The structure of the lower hinge is basically the same as that of the upper hinge. Hinge shaft mounting holes 321 corresponding to the square hinge shafts are provided at both ends of the mounting column, so that the two ends of the mounting column 3 can be fixed through the square hinge shafts 411. Specifically, in addition to the hinge fixing hole 412 (for fixing the hinge to the box), the upper hinge 41 is also provided with a second wire hole 413 for the door communication wire harness of the display assembly inside the box to pass through.

[0099] The utility model also provides a refrigerator, comprising the above-mentioned embedded door structure.

[0100] The refrigerator is embedded in the cabinet 0 (that is, when the door is closed, the front of the door is flush with the side fronts of the cabinet). For details, please refer to the visual interface of the cabinet door opening. Figures 10 to 12 , when the door is closed or opened to the maximum opening, it will not contact the right inner wall of the cabinet 0, realizing the structure of the built-in refrigerator.

[0101] The innovative design of the door and door mounting column structure of the built-in refrigerator realizes the displacement design of the refrigerator door and the rotating axis, so that when the refrigerator door is opened, the turning radius moves inward, controlling the extent of the refrigerator door protruding from the refrigerator body when it is opened. The fixed design of the door mounting column ensures that the door will not hit the cabinet wall during opening, which is convenient for installation, smooth opening and high stability. The display component is innovatively fixed on the door mounting column, and there is no need to set up a separate embedded box structure, which is simple to install and low in cost. The door communication harness is routed through the square hole between the door mounting column and the upper hinge, shortening the harness length. Since the upper hinge of the utility model is a fixed structure, the door harness routing is stable, solving the problem of the door harness falling off or wearing due to the door opening movement. The display component is set on the right side of the door body to facilitate user operation, improve human-computer interaction, and enhance user experience.

[0105] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0106] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0107] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
