Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a refrigeration equipment. Background Art

[0002] With the development of society and the gradual improvement of people's quality of life, people's demand for aesthetically pleasing home decoration has become increasingly prominent. Embedding refrigeration equipment (such as refrigerators) into external environmental components such as cabinets and walls to achieve a unified home decoration style has become popular. However, the door of traditional refrigeration equipment is configured to rotate around a fixed axis to open and close. During the rotation of the door, the pivot end of the door will protrude toward the external environmental component, causing interference with the external environmental component, affecting the opening of the door and the use of the refrigeration equipment.

[0003] The hinge device used in some existing refrigeration equipment includes a fixed hinge part fixed to the box body, a movable hinge part fixed to the door body, and a connecting rod assembly connected between the movable hinge part and the fixed hinge part. That is, a hinge device with a connecting rod assembly is used to movably connect the door body to the box body. During the process of opening the door body relative to the box body, under the drive of the connecting rod assembly, the door body rotates and translates along a preset trajectory. The structure is simple and can avoid interference between the door body and external environmental parts.

[0004] Among them, the existing fixed hinge and the box body or the movable hinge and the door body are generally fixed by two screws, which are affected by the interference of the connecting rod assembly, door closer components, damping components, etc. in the hinge device. For example, for the connection between the fixed hinge and the box body, the two screws are generally offset to the side of the fixed hinge part away from the support fulcrum to facilitate the installation of the screws, that is, the fixed point between the fixed hinge and the box body has a large force arm from the support fulcrum, and the door body itself is heavy, which makes the fixed hinge part easy to sink, and the corresponding door body will also sink, affecting the normal use of the user, such as causing the door body to be not tightly closed, resulting in loss of cold.

DETAILED DESCRIPTION

[0034] The following will be combined with the attached Figures 1-8 The specific embodiments shown are used to describe the present application in detail. However, these embodiments do not limit the present application, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all included in the scope of protection of the present application.

[0035] For the words expressing position and direction described in this application, the side where the door is located when the refrigerator is normally in use is referred to as "front", and the direction away from the refrigerator on the pivot side is referred to as "outside". For example, in a double-door refrigerator, the movement of one door from the pivot side away from the other door during the opening process is referred to as outward movement, and the movement of one door from the pivot side toward the other door during the opening process is referred to as inward movement.

[0036] The terms first, second, third, etc. in this application are only used to distinguish similar objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. In addition, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "connected", "fixed", etc. should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, and can be a fixed connection, a movable connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] Unless otherwise stated, the term "plurality" means two or more.

[0038] It should be noted that, in the absence of conflict, the specific embodiments and features in the embodiments disclosed in this application can be combined with each other.

[0039] Combine Figures 1-8 As shown, the present application provides a refrigeration device 100, which includes a housing 1 having an opening, a door 2 for opening or closing the opening, and a hinge device 3 that movably connects the door 2 to the housing 1. When the door 2 is closed, the door 2 and the housing 1 together enclose a closed refrigeration space. When the door 2 is open, it is convenient for a user to take items in and out of the opening.

[0040] Specifically, the hinge device 3 includes a hinge part fixed to the box body 1 and / or the door body 2, and a connecting rod assembly 33 movably connected to the hinge part and located between the door body 2 and the box body 1. The connecting rod assembly 33 includes a plurality of connecting rods hinged to each other. When the connecting rod assembly 33 is in a folded state, the plurality of connecting rods are in contact with each other. At this time, the door body 2 is in a closed state to close the opening. When the connecting rod assembly 33 is in an unfolded state, the plurality of connecting rods are away from each other. At this time, the door body 2 is in an open state to open the opening. In the process of the connecting rod assembly 33 gradually unfolding from the folded state, the connecting rod assembly 33 will drive the door body 2 to rotate and open, and will simultaneously drive the door body 2 to translate along a preset direction. Thus, interference between the door body 2 and external environmental parts can be avoided, and the applicable scenarios of the refrigeration equipment 100 can be expanded, such as embedded scenarios.

[0041] In one specific embodiment, the hinge comprises a fixed hinge 31 fixed to the box body 1, a movable hinge 32 fixed to the door body 2, and one end of the connecting rod assembly 33 is movably connected to the movable hinge 32, and the other end is movably connected to the fixed hinge 31. The hinge device 3 is modularly designed. When installing the hinge device 3, it is only necessary to fix the fixed hinge 31 to the box body and the movable hinge 32 to the door body 2. Then, the hinge device 3 can realize the movable connection between the door body 2 and the box body 1.

[0042] In this embodiment, the refrigeration device 100 is specifically described by taking the example that the door body 2 is located at the front side of the box body 1 and the door body 2 is a door that rotates left and right. Of course, it is understandable that this is not a limitation.

[0043] The hinge member has a supporting fulcrum A that cooperates with the connecting rod assembly 33 when the door body 2 is at its maximum opening angle. The refrigeration equipment 100 also includes a connecting structure provided between at least one of the hinge members and the housing 1 and the door body 2 on which the hinge member is provided, and the hinge device 3 is fixed to the housing 1 and / or the door body 2 via the connecting structure. The connecting structure includes a first connecting assembly 4 and a second connecting assembly 5. In an embodiment in which the door body 2 is located at the front side of the housing 1 and the door body 2 is a left-right rotating door, the first connecting assembly 4 and the second connecting assembly 5 are arranged at intervals along the left-right direction.

[0044] It can be known that the box body 1 or the door body 2 on which the hinge is provided can be understood as follows: when the hinge is a fixed hinge 31, the box body 1 or the door body 2 on which the hinge is provided refers to the box body 1; when the hinge is a movable hinge 32, the box body 1 or the door body 2 on which the hinge is provided refers to the door body 2.

[0045] When the connecting structure is provided between the fixed hinge 31 and the housing 1, the supporting fulcrum A corresponding to the connecting structure is the supporting fulcrum between the fixed hinge 31 and the connecting rod assembly 33. When the connecting structure is provided between the movable hinge 32 and the door body 2, the supporting fulcrum A corresponding to the connecting structure is the supporting fulcrum between the movable hinge 32 and the connecting rod assembly 33.

[0046] The following describes the connection structure in detail by assuming that the connection structure is provided between the fixed hinge 31 and the housing 1. Of course, it is understood that the connection structure is also applicable to the connection between the movable hinge 32 and the door 2. Correspondingly, the connection between the connection structure and the housing 1 and the fixed hinge 31 is also applicable to the connection between the connection structure and the door 2 and the movable hinge 32.

[0047] Specifically, the fixed hinge 31 includes a fixing plate 311 for fixing to the box body 1, and connecting plates 312 extending in the same direction from opposite ends of the fixing plate 311. One end of the connecting rod assembly 33 is movably connected to the two connecting plates 312. In other words, the cross-section of the fixed hinge 31 is U-shaped, which can improve the strength of the fixed hinge 31.

[0048] Specifically, the fixing plate 311 is parallel to the plane where the opening is located, and the connecting plate 312 is perpendicular to the plane where the opening is located.

[0049] It is known that when the connecting rod assembly 33 is in the folded state, the connecting rod assembly 33 will shield the fixing plate 311 from the front side of the fixing plate 311 . Therefore, the connecting rod assembly 33 is generally unfolded to facilitate the assembly of the hinge device 3 to the box body 1 .

[0050] In one embodiment, the support fulcrum A is the hinge point between the connecting rod assembly 33 and the fixed hinge 31. It is understood that during the unfolding and folding of the connecting rod assembly 33, the position of the hinge point between the connecting rod assembly 33 and the fixed hinge 31 remains unchanged, i.e., the fixed hinge 31 always supports the weight of the door body 2 at the hinge point. Of course, this is not limiting.

[0051] Combine Figure 2As shown, in a specific embodiment, the fixed hinge component 31 has a hinge point hinged to the connecting rod assembly 33 and a sliding groove 313 matched with the connecting rod assembly 33. Specifically, the connecting rod assembly 33 includes a first connecting rod 331 rotatably connected to the hinge point of the fixed hinge 31, a second connecting rod 332 rotatably and slidingly connected to the sliding groove 313 of the fixed hinge 31, and a third connecting rod 333 connecting the first connecting rod 331 and the movable hinge 32. The first connecting rod 331 intersects with the second connecting rod 332 and is rotatably connected at the intersection. The end of the second connecting rod 332 away from the sliding groove 313 is rotatably connected to the movable hinge 32, one end of the third connecting rod 333 is rotatably connected to the movable hinge 32, and the other end is rotatably connected to the end of the first connecting rod 331 away from the hinge point. The fixed hinge 31, the movable hinge 32, and the connecting rod assembly 33 form a five-link structure. When the connecting rod assembly 33 gradually unfolds from the folded state, the first connecting rod 331 rotates around the hinge point, and the second connecting rod 332 moves along the sliding groove 313 toward the hinge point. In this embodiment, the hinge point where the fixed hinge 31 and the first link 331 are hingedly connected serves as the support fulcrum A. That is, in this embodiment, there is only one support fulcrum A. Of course, this is not limiting. In other embodiments, the hinge point on the fixed hinge 31 and the corresponding position of the second link 332 and the slide slot 313 when the door body 2 is at its maximum opening angle may both serve as the support fulcrum A. Alternatively, in other embodiments, if the hinge device 3 has a six-link structure, there may be two hinge points between the link assembly 33 and the fixed hinge 31; or if the hinge device 3 has a five-link structure, but both the first link 331 and the second link 332 are hingedly connected to the fixed hinge 31; that is, if there are two hinge points between the link assembly 33 and the fixed hinge 31, both hinge points may serve as the support fulcrum A.

[0052] Specifically, combined Figures 4-5 As shown, the first connecting assembly 4 includes a first fixing hole 41 provided in the hinge member, a second fixing hole 42 provided in the housing 1 and corresponding to the first fixing hole 41, and a screw 43 that engages with the first fixing hole 41 and the corresponding second fixing hole 42. In one specific embodiment, the second fixing hole 42 is a threaded hole, and the screw 43 and the second fixing hole 42 are threadedly engaged to achieve a preliminary connection between the hinge member and the housing through the first connecting assembly 4. Of course, this is not limiting. In other embodiments, the second fixing hole 42 can also be configured as a through hole, in which case a nut is required to engage with the screw 43.

[0053] The second connecting assembly 5 is located on a side of the first connecting assembly 4 near the support fulcrum A. The second connecting assembly 5 includes a socket 51 provided on one of the fixed hinge 31 and the housing 1, and a post 52 provided on the other and mating with the socket 51. When installing the hinge assembly 3 to the housing 1, the post 52 is first directly inserted into the socket 51. Then, the connecting rod assembly 33 is unfolded, and the screw 43 is passed through the fixing hole 41 and fastened to the threaded hole 42, thereby securing the hinge assembly 3 to the housing 1. The refrigeration equipment 100 in the present application is provided with a second connecting component 5 which is matched with a column 52 and a socket 51 in an area near the supporting fulcrum A in the fixed hinge part 31 which is inconvenient for the user to touch during the installation of the hinge device 3. During the installation process, the column 52 is directly aligned with the socket 51 and inserted without any other operation by the user. This can reduce the force arm between the fixed point and the supporting fulcrum A between the hinge device 3 and the box body 1, greatly improve the connection strength between the fixed hinge part 31 and the box body 1, and avoid the fixed hinge part 31 from sinking, thereby improving the stability of the installation of the door body 2.

[0054] There is no particular limitation on the number of the first connecting components 4 , which can be one group or two groups.

[0055] In some optional embodiments, combined with Figure 2 As shown, along the arrangement direction of the first connecting assembly 4 and the second connecting assembly 5, the distance L between the second connecting assembly 5 and the support fulcrum A is no greater than 50 mm. That is, along the left-right direction, the distance L between the second connecting assembly 5 and the support fulcrum A is no greater than 50 mm. This can reduce the moment arm between the fixed point between the hinge device 3 and the housing 1 and the support fulcrum A, improve the connection strength between the fixed hinge member 31 and the housing 1, prevent the fixed hinge member 31 from sinking, and thus improve the installation stability of the door body 2.

[0056] In a specific embodiment, the plug post 52 is provided on the fixed hinge 31 and protrudes from the fixed hinge 31 toward the box 1 , and the insertion hole 51 is provided on the box 1 . Of course, this is not limited to the above.

[0057] In some optional embodiments, the insertion hole 51 is an elongated hole extending along the arrangement direction of the first connecting component 4 and the second connecting component 5, that is, the insertion hole 51 is an elongated hole extending in the left-right direction. After the insertion post 52 is inserted into the insertion hole 51, the hinge device 3 can be pre-positioned. By moving the insertion post 52 left and right, the fixing hole 41 and the corresponding threaded hole 42 are aligned, facilitating the subsequent fastening of the hinge device 3 to the housing 1 using the screws 43.

[0058] In a specific embodiment in which the insertion hole 51 is an elongated hole, the insertion hole 51 has a first end 511, a second end 512, and a transition section connecting the first end 511 and the second end 512. The diameter of the first end 511 is smaller than the diameter of the second end 512, and the diameter of the first end 511 is the same as the outer diameter of the post 52. When installing the hinge device 3, the post 52 is first inserted into the second end 512 of the insertion hole 51 to facilitate insertion of the post 52 into the insertion hole 51. The post 52 is then moved to the first end 511. At this point, the fixing hole 41 is aligned with the corresponding threaded hole 42, facilitating the connection and assembly between the hinge device 3 and the housing 1.

[0059] In a specific embodiment, combined with Figure 2 、 Figure 4 As shown in FIG, the plug is a cylinder with the same diameter. Figure 7 As shown, in another specific embodiment, the second connecting component 5a further includes a limiting post 53 provided at one end of the plug post 52 facing the insertion hole 51. The outer diameter of the limiting post 53 is larger than the outer diameter of the plug post 52, and the outer diameter of the limiting post 53 is no larger than the aperture of the second end 512. When installing the hinge device 3, the plug post 52 is inserted into the insertion hole 51 while the limiting post 53 is passed through the insertion hole 51. After the plug post 52 is moved to the first end 511, the limiting post 53 abuts against the periphery of the first end 511 of the insertion hole 51, thereby preventing the plug post 52 from falling out of the insertion hole 51 and further improving the stability of the connection between the fixed hinge member 31 and the box body 1.

[0060] Specifically, the insertion column 52 and the limiting column 53 are an integrated structure, which can further improve the stability of the connection between the fixed hinge 31 and the box body 1.

[0061] In some optional embodiments, one end of the post 52 has a rivet head. When the post 52 is mounted on the fixed hinge 31, the rivet head secures the post 52 to the fixed plate 311. When the post 52 is mounted on the case 1, the rivet head secures the post 52 to the case 1. This facilitates a secure connection between the post 52 and the fixed hinge 31 or the case 1.

[0062] Specifically, the box body 1 includes a box wall 11 located at the hinge device 3 and a reinforcing iron 6 installed on the inner side of the box wall 11. The threaded hole 42 and the insertion hole 51 are through holes that penetrate the box wall 11 and the reinforcing iron 6, which can further improve the connection strength between the fixed hinge 31 and the box body 1.

[0063] Specifically, the box wall 11 includes a crossbeam located between the two refrigeration compartments, an upper beam located above the uppermost refrigeration compartment, and a lower beam located below the lowermost refrigeration compartment.

[0064] In some optional embodiments, the refrigeration equipment 100 also includes an embedded box 7 that shields the socket 51 from the inner side of the box wall 11, and the embedded box 7 has a clearance cavity 71 connected to the socket 51, and the clearance cavity 71 is used to make way for the plug column 52 / limit column 53.

[0065] Specifically, the embedded box 7 is provided on the inner side of the reinforcing iron 6 to prevent overflow of the box body 1 during foaming.

[0066] Specifically, for the threaded hole 42 , overflow of the threaded hole 42 can be avoided by attaching anti-overflow tape on the inner side of the box wall 11 , that is, anti-overflow tape is attached on the inner side of the position corresponding to the reinforcing iron 6 and the threaded hole 42 to avoid overflow of the threaded hole 42 .

[0067] In some optional embodiments, the fixing hole 41 is an elongated hole extending along the arrangement direction of the first connecting component 4 and the second connecting component, so as to facilitate the fixed connection between the hinge device 3 and the box body 1 .

[0068] Among them, when there are two groups of first connecting components 4, the fixing holes 41 in one group can be set as elongated holes, and the fixing holes 41 in the other group can be set as round holes that match the threaded holes 42; or the fixing holes 41 in both groups can be set as elongated holes.

[0069] The elongated hole refers to a non-circular hole, and may be formed by two circular holes connected to form the elongated hole.

[0070] In some optional embodiments, combined with Figure 8 As shown, the door body 2 includes an end trim strip, which includes a trim strip body 21 and a shielding cover 22. The trim strip body 21 is recessed with an installation cavity 211 for accommodating the hinge device 3. The installation cavity 211 has a cavity bottom wall 2111 and a cavity side wall 2112 located at the end of the cavity bottom wall 2111 away from the box body 1. The shielding cover 22 is connected to the end of the cavity side wall 2112 away from the cavity bottom wall 2111, and extends toward the direction of the box body 1. The shielding cover 22 can shield the hinge device 3 from the front, improving the overall appearance of the door body 2. At the same time, the shielding cover 22 can also prevent the user's hand from reaching between the connecting rods in the connecting rod assembly 33, thereby preventing the user from being pinched and improving the safety performance of the hinge device 3.

[0071] Specifically, the length of the shielding cover 22 extending in the direction of the box body can be set according to specific needs.Figure 8 As shown in the shielding cover 22a, the shielding cover 22a extends longer toward the direction of the box body and is opposite to the cavity bottom wall 2111; Figure 8 As shown in the shielding cover 22b, the shielding cover 22b extends shorter toward the direction where the box is located. At this time, it mainly plays a role in improving the overall appearance of the door body 2.

[0072] To sum up, the refrigeration equipment 100 in the present application is provided with a second connecting component 5 which is matched with the column 52 and the socket 51 in the area near the support point A which is inconvenient for the user to touch during the installation of the hinge device 3. During the installation process, the column 52 and the socket 51 can be directly aligned and inserted without any other operation by the user. This can reduce the force arm between the fixed point between the hinge device 3 and the box body 1 / door body 2 and the support point A, can greatly improve the connection strength between the hinge part and the box body 1 / door body 2, avoid the hinge part from sinking, and thus improve the stability of the installation of the door body 2.

[0073] The above embodiments are intended only to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to preferred embodiments, for example, if the techniques in different embodiments can be used in combination to simultaneously achieve corresponding effects, such solutions are also within the scope of protection of the present application. It should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
