Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and particularly to an embedded refrigerator and an installation structure of an embedded refrigerator. Background Art

[0002] For a fully embedded refrigerator, its door body is usually connected to the cabinet body by hinges. Common hinges include multi-link hinges and double-axis hinges. Among them, the multi-link hinge includes multiple sections of structures, and the multiple sections are rotationally connected by rotating shafts. This kind of link hinge structure is complex and the cost is relatively high. The two parallel rotating shafts of the double-axis hinge move along different grooves according to their respective trajectories, thereby driving the refrigerator door to move along a specific trajectory. Its structure is simpler than that of the multi-link hinge. However, since the two parallel rotating shafts move along different grooves according to their respective trajectories, the opening of the fully embedded refrigerator is not smooth enough. In addition, in order to make the front of the embedded refrigerator look better visually, the outer edge of the door body is usually set to protrude from the cabinet body to ensure that the gap between the embedded refrigerator and the cabinet is small enough. However, this causes the hinge to easily interfere with the door body. Summary of the Utility Model

[0003] Based on this, it is necessary to provide an embedded refrigerator and an installation structure of an embedded refrigerator with a simple hinge structure, smooth door opening, and the hinge and the door body are not prone to interference.

[0004] An embedded refrigerator includes a cabinet body, a door body, and a first hinge. The first hinge is fixedly installed on the top of the cabinet body, and the first hinge has a cantilever extending towards the top of the door body. A first rotating shaft is provided at the end of the cantilever. The height of the door body is greater than the height of the cabinet body, and a sinking groove is provided at the top of the door body corresponding to the cantilever. The first rotating shaft is movably inserted into the bottom wall of the sinking groove. Among them, the door body has an open state and a closed state, and the door body can rotate around the first rotating shaft to switch between the open state and the closed state.

[0005] In one embodiment, along the height direction of the cabinet body, there is a spaced arrangement between the cantilever and the bottom wall of the sinking groove to form an assembly gap.

[0006] In one embodiment, the sinking groove has side walls, and the shape of the side walls is adapted to the shape of one side edge of the cantilever. And when the door body is in the closed state, one side edge of the cantilever is in a stop fit with the side walls.

[0007] In one embodiment, the embedded refrigerator further includes a second hinge. The second hinge is fixedly installed on the cabinet body. The second hinge is provided with a second rotating shaft, and the second rotating shaft is correspondingly movably inserted into the bottom of the door body, and the second rotating shaft is coaxially arranged with the first rotating shaft.

[0008] In one embodiment, the second hinge is provided with a guide groove, which extends in an arc shape around the second rotating shaft, and a limit block is provided at the bottom of the door body, which is movably clamped in the guide groove; and when the door body is in an open state, the limit block stops at the first end of the guide groove, and when the door body is in a closed state, the limit block stops at the second end of the guide groove.

[0009] In one embodiment, when the limiting block stops at the first end of the guide groove, an angle α is formed between the door body and the cabinet body, and 130°≤α≤136°.

[0010] In one embodiment, the door body includes a steel plate layer, a door liner layer and a wooden board layer. The door liner layer is located on the side of the steel plate layer close to the cabinet body, and the wooden board layer is located on the side of the steel plate layer away from the cabinet body. In addition, along the width direction of the built-in refrigerator, the outer edge of the wooden board layer protrudes from the steel plate layer.

[0011] In one embodiment, the outer edge of the wood layer is provided with a cut corner, and the cut corner is opened at the corner of the outer edge close to the cantilever.

[0012] In one embodiment, the steel plate layer is provided with an avoidance protrusion corresponding to the first rotating shaft, and the avoidance protrusion protrudes outward along the radial direction of the first rotating shaft. The wooden board layer is provided with an accommodating groove corresponding to the avoidance protrusion, and the avoidance protrusion is clamped in the accommodating groove.

[0013] A built-in refrigerator installation structure includes a cabinet and the built-in refrigerator described in any one of the above embodiments. The cabinet has a storage space, the storage space has an opening, the built-in refrigerator is installed in the storage space through the opening, and the built-in refrigerator does not protrude from the opening.

[0014] Compared to multi-link hinges or biaxial hinges in related structures, the first hinge in this application, by providing a cantilever and a single first rotating shaft, enables the door body to be opened or closed by rotating about the first rotating shaft. This not only simplifies the coordination between the door body and the first hinge, but also simplifies the first hinge structure, thereby reducing costs. Furthermore, by providing a sunken groove at the top of the door body corresponding to the cantilever, the sunken groove provides a clearance space for the first hinge, thereby preventing interference between the first hinge and the door body.

[0028] Please refer to Figures 1 to 3 , this application provides an embedded refrigerator 100, which includes a cabinet body 10, a door body 20 and a first hinge 30. The first hinge 30 is fixedly installed on the top of the cabinet body 10, and the first hinge 30 has a cantilever 31 extending towards the top of the door body 20. A first rotating shaft 32 is provided at the end of the cantilever 31. The height of the door body 20 is greater than that of the cabinet body 10, and a sinking groove 21 is formed in the top of the door body 20 corresponding to the cantilever 31. The first rotating shaft 32 is movably inserted into the bottom wall 211 of the sinking groove 21. Wherein, the door body 20 has an open state and a closed state, and the door body 20 can rotate around the first rotating shaft 32 to switch between the open state and the closed state.

[0029] It should be noted that the top of the cabinet body 10 and the top of the door body 20 both refer to the top along the height direction of the built-in refrigerator 100, and the built-in refrigerator 100 includes, but is not limited to, a fully built-in cross refrigerator. Compared with the multi-link hinge or the double-axis hinge in the related structure, the first hinge 30 in the present application enables the door body 20 to be opened or closed by rotating around the first rotating shaft 32 by providing the cantilever 31 and a single first rotating shaft 32. This not only makes the cooperation mode between the door body 20 and the first hinge 30 simpler, but also makes the structure of the first hinge 30 simpler, thus facilitating cost reduction. Moreover, by providing a sinking groove 21 corresponding to the cantilever 31 at the top of the door body 20, the sinking groove 21 provides an avoidance space for the first hinge 30, thereby facilitating the prevention of interference between the first hinge 30 and the door body 20.

[0030] Further, along the height direction of the cabinet body 10, the cantilever 31 and the bottom wall 211 of the sinking groove 21 are spaced apart to form an assembly gap 34. By providing the assembly gap 34, the cantilever 31 does not contact the bottom wall 211 of the sinking groove 21, thereby preventing interference between the cantilever 31 and the bottom wall 211 of the sinking groove 21, enabling the door body 20 to rotate more smoothly around the first rotating shaft 32.

[0031] Exemplarily, the first hinge 30 further includes a mounting seat 33, the mounting seat 33 is detachably mounted on the top of the cabinet body 10, the cantilever 31 is connected to the mounting seat 33, and the height of the cantilever 31 is greater than the height of the mounting seat 33. That is, the cantilever 31 is raised relative to the mounting seat 33, thus facilitating the spaced arrangement between the cantilever 31 and the bottom wall 211 of the sinking groove 21.

[0032] The sinking groove 21 has a side wall 212, the shape of the side wall 212 is adapted to the shape of one side edge of the cantilever 31, and when the door body 20 is in the closed state, one side edge of the cantilever 31 is in a stop fit with the side wall 212. In this way, when the door body 20 is closed, the side wall 212 of the sinking groove 21 can prevent the door body 20 from shaking by being in a stop fit with one side edge of the cantilever 31.

[0033] Specifically, the sinking groove 21 is opened at the corner of the top end of the door body 20 close to the first hinge 30. The side wall 212 of the sinking groove 21 and one side edge of the corresponding cantilever 31 both extend in an arc shape.

[0034] As Figure 4 and Figure 5 shown, the built-in refrigerator 100 further includes a second hinge 40, the second hinge 40 is fixedly mounted on the cabinet body 10, the second hinge 40 is provided with a second rotating shaft 41, the second rotating shaft 41 is correspondingly and movably inserted into the bottom of the door body 20, and the second rotating shaft 41 is coaxially arranged with the first rotating shaft 32. In this way, the door body 20 can be opened and closed more smoothly around the first rotating shaft 32 and the second rotating shaft 41.

[0035] The second hinge 40 defines a guide slot 42 extending in an arc shape around the second rotation axis 41. A stopper 22 is provided at the bottom of the door body 20 and movably engages within the guide slot 42. When the door body 20 is open, the stopper 22 abuts against a first end 421 of the guide slot 42. When the door body 20 is closed, the stopper 22 abuts against a second end 422 of the guide slot 42. It will be appreciated that the guide slot 42 cooperates with the stopper 22 to limit the rotational trajectory of the door body 20.

[0036] Among them, when the limit block 22 stops at the first end 421 of the guide groove 42, an angle α is formed between the door body 20 and the cabinet body 10, and 130°≤α≤136°. It can be understood that when the limit block 22 stops at the first end 421 of the guide groove 42, the door body 20 reaches the maximum door opening angle, that is, the angle α. The value of α can be 130°, 132°, 133°, 134°, 135°, 136°, etc., which can be set according to actual needs and are not listed here one by one. For a fully embedded cross refrigerator, limiting the maximum door opening angle can avoid collision between the door body 20 and the cabinet 200.

[0037] like Figure 6 As shown, the door body 20 includes a steel plate layer 23, a door lining layer 24, a wood layer 25, and a frame 26. The door lining layer 24 is located on the side of the steel plate layer 23 close to the cabinet body 10, the wood layer 25 is located on the side of the steel plate layer 23 away from the cabinet body 10, and the frame 26 is arranged around the outer periphery of the door lining layer 24. Along the width direction of the built-in refrigerator 100, the outer edge 251 of the wood layer 25 protrudes from the steel plate layer 23. It can be understood that the wood layer 25 is located at the outermost layer of the door body 20. By arranging the outer edge 251 of the wood layer 25 protruding from the steel plate layer 23 along the width direction of the built-in refrigerator 100, a relatively small assembly gap can be ensured between the door body 20 and the cabinet 200.

[0038] Along the width direction of the built-in refrigerator 100 , the cantilever 31 is bent in a direction away from the outer edge 251 of the wooden board layer 25 so as to avoid the outer edge 251 of the wooden board layer 25 .

[0039] Furthermore, the outer edge 251 of the wood layer 25 is provided with a chamfer 251a, which is provided at the corner of the outer edge 251 near the cantilever 31. The chamfer 251a is also called a chamfer. By providing the chamfer 251a, it is possible to prevent the outer edge 251 of the wood layer 25 from forming a protruding sharp corner, thereby further preventing the outer edge 251 of the wood layer 25 from interfering with the cantilever 31.

[0040] The steel plate layer 23 is provided with an avoidance convex part 241 corresponding to the first rotating shaft 32. The avoidance convex part 241 protrudes radially outward along the first rotating shaft 32. The wooden board layer 25 is provided with a receiving groove 252 corresponding to the avoidance convex part 241, and the avoidance convex part 241 is clamped in the receiving groove 252. By providing the avoidance convex part 241 and the receiving groove 252, the structure of the door body 20 is made more compact.

[0041] Please continue to refer to Figure 1 , this application also provides an embedded refrigerator installation structure 1. The embedded refrigerator installation structure 1 includes a cabinet 200 and the embedded refrigerator 100 described in any one of the above embodiments. The cabinet 200 has a receiving space 210, and the receiving space 210 has an opening 220. The embedded refrigerator 100 is installed into the receiving space 210 through the opening 220, and the embedded refrigerator 100 is not set to protrude from the opening 220.

[0042] 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 described in this specification.

[0043] The above embodiments only represent several implementation manners of this application. The description is relatively specific and detailed, but it cannot be understood as a limitation to 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 this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the patent protection scope of this application should be subject to the appended claims.
