A refrigerator is a household appliance used to store food and other items in a cool environment to keep them fresh. It usually consists of a freezer compartment and a refrigerator compartment, with the freezer compartment used for freezing food and the refrigerator compartment used for preserving freshness. With the development of the times, in order to release more space and ensure aesthetics, more and more users use built-in refrigerators. The flat-embedded refrigerator is a setting method of the built-in refrigerator, and its biggest feature is that the door body is flush with the cabinet, and from the side, it is integrated and has a better overall appearance.

[0003] However, for refrigerators, in order to prevent the door body from interfering with the cabinet and the environment structure when opening and closing the door, some refrigerators use special hinge structures for rotating connection between the cabinet and the door body, such as a double-axis double-groove hinge structure with a special trajectory, such as a Chinese patent application with publication number CN118008067A, which discloses a door assembly and a refrigeration equipment. The door assembly includes a double-axis double-groove hinge structure.

[0004] In the initial stage of opening the door, since the user usually holds the door body on the opening and closing side to open and close the door body, the opening force is generally perpendicular to the door body, and in the cooperating trajectory of the double-axis double-groove hinge structure with a special trajectory, at the moment of opening the door, the opening force has a large deviation from the direction of motion of the hinge structure, which may cause a jamming problem during the opening and closing of the door body.

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] In the description of the present application, it should be understood that the orientation description, such as the orientation or position relationship indicated by the upper, lower, front, rear, left, right, etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as a limitation on the present application. The device or element indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0033] In the description of the utility model, the meaning of several is one or more, the meaning of multiple is two or more, greater than, less than, exceed and the like are understood as not including the number, above, below, within and the like are understood as including the number.If there is a description to the first, the second is only used for distinguishing technical features for the purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0034] Please refer to Figures 1-5 The opening and closing type refrigeration equipment mentioned in the utility model is a low-temperature storage device such as a refrigerator, a freezer, an ice bar and the like.Of course, the refrigeration equipment can also be other equipment having a cabinet 1 and a door assembly, and requiring the door assembly to be able to rotate relative to the cabinet 1.The description of the refrigeration equipment described below in the embodiments of the application is described by taking a refrigerator as an example, and the example is only required for discussion, and does not limit the specific form of the refrigeration equipment.

[0035] When the door body 2 is installed to the fixed cabinet 1 or door frame through the hinge assembly, the door body 2 can interfere with the cabinet 1 or the door frame or the environment structure (the environment structure can be understood as a wall, a cabinet, an electrical appliance and the like.) during movement, and some hinge structures can have the possibility that the door seal is laterally extruded and deformed, affecting the sealing effect.To solve the above problems, some refrigerators can adopt a hinge structure with a special trajectory to rotatably connect the cabinet 1 and the door body 2, such as a double-shaft double-groove hinge structure.The door body 2 and the cabinet 1 are rotatably connected and include a hinge side and an opening and closing side after being rotatably connected, the hinge side is one end of the door body 2 connected with the cabinet 1, and the opening and closing side is the other end opposite to the hinge side.

[0036] However, in the initial stage of opening the door, the user usually holds the door body 2 of the opening and closing side to open and close the door body 2.In the matching trajectory of the above-mentioned double-shaft double-groove, at the moment of opening the door, there is a large deviation between the opening force and the movement direction of the hinge structure, which can cause the door body 2 to have a jamming problem during opening and closing.The existence of the matching gap between the shaft body 3 and the groove body 4 can cause a certain shaft body 3 to have a false movement center in the moment of opening and closing (such as Figure 1 ), which can further increase the possibility of jamming.

[0037] Please refer to Figures 2-5To solve the above problems, the refrigerator provided by the present application comprises a cabinet 1, a door body 2, and a hinge structure for rotationally connecting the two. The hinge structure can comprise a first hinge member and a second hinge member. When one of the first hinge member and the second hinge member is mounted on the door body 2 and the other is mounted on the cabinet 1 or a door frame, the opening and closing control of the door body 2 can be realized. The refrigerator further comprises a hinge auxiliary structure comprising a first body and a second body. The first body can be one of the first hinge member and the second hinge member, and the second body can be the other of the first hinge member and the second hinge member. The first body can be the cabinet 1 or the door body 2 itself, or a separate component structure fixedly connected to the cabinet 1 or the door body 2. As an example, the first body is taken as the first hinge member fixedly connected to the cabinet 1 structure, and the second body is taken as the second hinge member fixedly connected to the door body 2 for detailed description.

[0038] Please refer to Figures 2-5 In one embodiment of the present application, the first body comprises a thrust member, and the second body comprises a guide inclined surface. The included angle between the guide inclined surface and the opening and closing side of the door body 2 is an acute angle. One of the first body and the second body is fixed to the door body 2. When the door body 2 is in a closed state, the thrust member is in contact with the guide inclined surface, and the included angle between the normal line of the contact point on the guide inclined surface and the door-cabinet mating surface satisfies 90°≥x>0°. In this way, at the moment of opening the door, the opening force F of the user acts on the opening and closing side, regardless of the change of the force direction of the door body 2, under the action of the reaction force, through the cooperation of the thrust member and the guide inclined surface, the thrust member applies a force F1 to the door body 2 through the guide inclined surface, the force F1 is along the normal direction of the contact point of the guide inclined surface, and there is always a component force in the negative direction of the y-axis (in the perspective view, the side of the cabinet 1 is taken as the y-axis, and the joint surface of the cabinet 1 and the door body 2 is taken as the x-axis to establish a coordinate system), so that the movement of the hinge side of the door body 2 and the rotation of the door body 2 are synchronized, and the door body 2 is prevented from being stuck at the moment of opening.

[0039] Please refer to Figures 2-5 In one embodiment of the present application, the implementation form of the thrust member is not limited, which can be a cam structure, a piston (top rod) structure, a shaft body 3 structure, or other forms. When the structure form of the thrust member changes, the guide inclined surface is adapted accordingly. When the thrust member is a cam structure, the outer cylindrical surface of the cam structure can be in contact with the guide inclined surface. When the thrust member is a piston top rod structure, the free end of the piston top rod can be in contact with the guide inclined surface.

[0040] Please refer to Figures 2-5In one embodiment of the utility model, as an example, the thrust piece is a shaft body 3, and the guide inclined surface is a side wall of a groove 4 provided on the second body. Preferably, when the door body 2 is in a closed state, the included angle between the normal line of the guide inclined surface passing through the contact point and the door and box mating surface satisfies 90 DEG >= x > 45 DEG, so that the separation in the negative direction of the y axis can fully play the role of promoting the box body 1 to move away from the door body 2, avoiding the jamming condition. Further, the side wall of the groove 4 includes an arc-shaped transition surface in communication with the guide inclined surface, and the transition surface is located at one end close to the hinged side, so that the shaft body 3 can smoothly move relative to the groove 4 during the opening of the door body 2. The groove 4 includes an avoiding gap. The avoiding gap can be provided as an arc-shaped structure and is located at one end of the transition surface close to the hinged side, so that the thrust piece can be avoided when the hinged piece rotates to a large angle if necessary.

[0041] The above describes one embodiment of the utility model in detail, but the content is only the preferred embodiment of the utility model and cannot be considered to limit the implementation range of the utility model. Any equivalent change and improvement within the application range of the utility model should still belong to the scope of the claims of the utility model.
