DETAILED DESCRIPTION

[0031] The present application will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and any changes in structure, method, or function made by those of ordinary skill in the art based on these embodiments are included in the protection scope of the present application.

[0032] It should be understood that terms such as "upper", "above", "lower", "below", and the like used herein to describe spatial relative positions are for the purpose of facilitating description to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatial relative position terms can be intended to include different orientations of the device in use or in operation other than the orientation shown in the drawings.

[0033] An embodiment of the present application provides an embedded hinge device and a refrigeration equipment having the same, which is used to realize embedded installation of the equipment, especially for embedded installation of the refrigeration equipment, and achieves the technical effects of convenient installation and beautiful appearance.

[0034] The refrigeration equipment of the present embodiment can be provided as a refrigerator, a wine cabinet, a freezer, an ice cabinet, and the like, and is especially suitable for a refrigerator, and more particularly for an embedded refrigerator. The side surface of the refrigerator can be closely attached to a wall or a cabinet body 400. The refrigerator includes a cabinet 200, a door body 300, and the embedded hinge device 100 of the present embodiment. The door body 300 of the embedded refrigerator can be flush with the outer surface of the side cabinet body 400, forming a beautiful whole. The door body 300 is rotatably connected to the cabinet 200 by the embedded hinge device 100, and is used to open and close the cabinet 200.

[0035] In addition, the embedded hinge device 100 can also be used in other devices, as long as the device is provided with a body and a door body 300 which can be opened or closed relative to the body. The embedded hinge device 100 is used to connect the body and the door body 300 of the device, and to realize that the door body 300 can be opened at an angle or closed relative to the body, while making it possible to install the device in an embedded form, such as an embedded microwave oven, an embedded dishwasher, an embedded oven, etc.

[0036] In order to clearly express the positions and directions described in the present embodiment, in the present embodiment, the direction in which the door body 300 is opened is defined as front, the opposite direction is defined as back, the direction which can be referred to gravity is defined as down, the opposite direction is defined as up, the user stands in front of the refrigerator, and the two sides of the refrigerator are respectively defined as left and right, Figure 1 、 Figure 6 、 Figure 8 In the present embodiment, the process of opening the door body 300 on the right side of the refrigerator is taken as an example for explanation and description, and the side wall 201 of the cabinet 200 is taken as an example, and the right side of the right side wall 201 is provided with the cabinet 400.

[0037] The embedded hinge device 100 includes an upper embedded hinge device 100 and a lower embedded hinge device 100, the upper embedded hinge device 100 is arranged above the door body 300 and the cabinet 200, and the lower embedded hinge device 100 is arranged below the door body 300. The connection structures of the upper embedded hinge device 100 and the lower embedded hinge device 100 with the door body 300 and the cabinet 200 are symmetrically arranged, and the only difference between the upper embedded hinge device 100 and the lower embedded hinge device 100 is that the lower embedded hinge device 100 also plays a role of supporting the gravity of the door body 300 under stress, but the structure of the lower embedded hinge device 100 is the same as that of the upper embedded hinge device 100. The mounting position of the hinge device 100 in the present embodiment and the corresponding relationship between the hinge state and the rotation angle of the door body 300 will be described in detail below. Figure 1 、 Figure 6 、 Figure 8

[0038] The embedded hinge device 100 of the present embodiment includes a hinge seat 10, a rotating part 20, a linkage part and a limiting part 50, wherein the hinge seat 10 is fixedly connected to the cabinet 200, the rotating body 22 is fixedly connected to the door body 300, the rotating part 20 controls the opening path and the overturning opening movement mode of the door body 300, and ensures that the door body 300 will not squeeze the cabinet 200 and will not collide with the wall or the cabinet 400 on the side during the opening process.

[0039] ​The rotating part 20 of the embedded hinge device 100 comprises a first gear 21 and a rotating body 22 fixedly connected to the axis of the first gear 21. The rotating body 22 is fixedly connected to the axis of the first gear 21, which means that it is distinguished from eccentric motion. The axis of rotation of the rotating body 22 coincides with the axis of rotation of the first gear 21, and the rotating angular velocity of the rotating body 22 is consistent with that of the first gear 21.

[0040] The hinge seat 10 supports and fixes the hinge device 100. The hinge seat 10 comprises a first guide part 40, and the linkage part comprises a second guide part and a second gear 30. The first guide part 40 guides the second guide part to reciprocate along a first preset track. The second guide part is connected to the second gear 30. The cooperation between the first guide part 40 and the second guide part adds a degree of freedom to the second gear 30, so that the second gear 30 can move in a plane perpendicular to the axis of rotation of the second gear 30 while rotating. The first gear 21 and the second gear 30 can be as shown in Figure 3 The first gear 21 and the second gear 30 are not complete gears. By controlling the size and transmission ratio, the rotating angle of the first gear 21 and the second gear 30 can not reach 360°, so that the coverage range of the gear teeth can meet the requirement of engagement at all times within the rotating range. The first guide part 40 and the second guide part can be a groove and a slider in the groove, respectively. The shape of the groove is a hole along the first preset track, so as to achieve the guided effect of movement along the groove.

[0041] The limiting part 50 comprises a first limiting member and a second limiting member. The first limiting member is rotatably connected to the axes of the first gear 21 and the second gear 30. The second limiting member limits the reciprocating movement of the linkage part and / or the rotating part 20 along a second preset track. The first limiting member ensures the engagement of the first gear 21 and the second gear 30 at all times, and tightens the first gear 21 while the gears are engaged, so as to prevent the first gear 21 from moving away from the second gear 30. The second limiting member is mainly used to guide the movement of the first gear 21 along the second preset track, so as to achieve the purpose of moving the first gear 21 along the expected planning path.

[0042] The second preset track has a component in the direction away from the box body 200 of the opening 202 and a component in the direction of the side wall 201 towards the box body 200. In this embodiment, the direction away from the box body 200 of the opening 202 can be described as the front of the box body 200, and the direction away from the box body 200 of the side wall 201 can be described as the left of the box body 200, for example, the right door body 300 in this embodiment. The second preset track of the hinge at the upper right corner is inclined to the left front of the box body 200. The left front of the second preset track can be a straight line or an arc towards the left front, so as to move the first gear 21 to the left front to open the door body 300 or to the right rear to close the door body 300.

[0043] Under the limitation of the second preset track, when the door body 300 is opened, the first gear 21 will move to the right front, and correspondingly, the door body 300 will not only move forward, but also move left, the forward movement can move away from the cabinet 200 to avoid interference between the door body 300 and the cabinet 200, and the left movement can avoid interference with the space on the right side of the cabinet 200. For scenes with high embedding level requirements, that is, occasions where the space reserved outside the side wall 201 of the cabinet 200 is small, the movement of the door body 300 to the side of the side wall 201 is reduced, such as the left movement of the door body 300 in this embodiment, so that the door body 300 does not interfere with the left cabinet 400 after being opened. The second preset track of this embodiment can design different tracks according to the needs of different embedding levels, so as to balance between the left movement without interference with the side cabinet 400 and the specific value of the right space to determine the amount of left movement.

[0044] Since the axis of the first gear 21 and the movement path of the limiting rod 521 of the second preset track are both fixed on the sleeve plate 51 of the limiting part 50, the axis of the first gear 21 will also move, when the second preset track is a straight line, the axis of the first gear 21 also moves along the straight line, and when the movement path of the second preset track is an arc, the axis of the first gear 21 also rotates along the arc.

[0045] In this embodiment, the first limiting groove 12 includes a plurality of arc-shaped grooves, as shown in Figures 3-5 The centers of the arc-shaped grooves are the same, and the arc-shaped grooves have a component in the direction away from the cabinet 200 and a component in the direction of the side wall 201 towards the cabinet 200. That is, the arc-shaped groove extends to the left front direction. The center of the arc-shaped groove is located outside the second limiting part and on the side away from the axis of the first gear 21. This arrangement allows the sleeve plate 51 to have a larger swing amount, which is more conducive to making the first gear 21 make any expected movement trajectory to the left front.

[0046] In addition, in this embodiment, the radius of the arc-shaped groove is much larger than the size of the hinge device 100, so the first limiting groove 12 can also be approximately regarded as a straight groove, at this time, the displacement amount of the limiting rod 521 moving left, that is, the amount of the axis of the first gear 21 moving left is approximately equal, and the displacement amount of the limiting rod 521 moving forward, that is, the amount of the axis of the first gear 21 moving forward is approximately equal.

[0047] Further, the side wall 201 is provided with a preset gap 203 away from one side of the cabinet 200, and the door body 300 includes a corner 301 away from the cabinet 200, and the corner 301 is arranged on the side of the door body 300 close to the side wall 201, the distance from the axis of the first gear 21 to the corner 301 minus the length of the second preset track in the direction perpendicular to the side wall 201 is less than the sum of the distance from the axis of the first gear 21 to the side wall 201 and the thickness of the preset gap 203 when the door body 300 closes the opening 202, as shown in Figure 7 The preset gap 203 is the gap between the refrigeration equipment and the side cabinet 400. In addition, the first limiting groove 12 is provided as a straight groove or an arc-shaped groove with a radius much larger than the size of the hinge device 100, so that the displacement of the limiting rod 521 moving to the left is approximately equal to the displacement of the axis of the first gear 21 moving to the left.

[0048] When the above size conditions are met, the door body 300 can be controlled to always avoid collision with the side cabinet 400 during opening. For the embedded refrigerator, the gap between the refrigerator and the side cabinet 400 or the wall is different under different embedded level requirements. When the embedded level is higher, the value of the preset gap 203 is smaller. For example, the maximum preset gap 203 on the side is 30 mm, and when the embedded level requirement is higher, it can be 20 mm. The higher the embedded level, the less the door body 300 can extend outward.

[0049] The distance L1 from the axis of the first gear 21 to the corner 301, the length L2 of the second preset track in the direction perpendicular to the side wall 201, the distance L3 from the axis of the first gear 21 to the side wall 201 when the door body 300 closes the opening 202, and the thickness L4 of the preset gap 203 satisfy L1-L2

[0050] In addition, when the door body 300 is arranged on the left side of the cabinet 200, that is, the hinge device 100 is also located on the left side of the cabinet 200, the second preset track at this time is directed to the right front, which can also be a straight line or an arc.

[0051] In Figure 1 , the door body 300 is in a closed state, and the embedded hinge device 100 is as shown in Figure 2 , 4 , 5, when the door body 300 is opened by a certain angle, such as about 45°, as shown in Figure 6 , the embedded hinge device 100 is as shown in Figure 7 , when the door body 300 is opened by a larger angle, such as about 90°, as shown inFigure 8 At this time, the hinge device 100 is as shown in Figure 9 .

[0052] Further, the hinge seat 10 comprises a support, the limiting part 50 comprises a sleeve part slidingly connected to the support, and the rotating part 20 is rotatably connected to the sleeve part at the axis of the first gear 21. For the lower-embedded hinge device 100, the gravity and torque of the door body 300 need to be borne, and the rotating body 22 of the lower-embedded hinge device 100 is connected to the door body 300. The gravity of the door body 300 acts on the rotating part 20. By rotatably connecting the rotating part 20 to the sleeve part at the axis of the first gear 21, the sleeve part bears the gravity of the door body 300, and the sleeve part is slidingly connected to the support, so that the support bears the role of supporting the door body 300.

[0053] In the embodiment, the first limiting part, the second limiting part, and the sleeve part are integrally formed, and the three parts together form a structure as shown in Figure 2 or 3. In the structure of the limiting part 50 in the figure, the relative fixation of the first gear 21 and the second gear 30, the support of the door body 300, and the guidance of the linkage part and / or the rotating part 20 along the second preset track are simultaneously realized.

[0054] The second limiting part and the support are slidingly connected. In an embodiment, the second limiting part or the support comprises a limiting sliding block and a limiting groove, the limiting groove is arranged along the second preset track, and the limiting sliding block is inserted into the limiting groove.

[0055] In another embodiment, as shown in Figure 2 , 4 , 5, 7, 9, the support comprises a support body 11 and a first limiting groove 12 arranged on the support body 11, and the second limiting part comprises a second limiting groove and a plurality of limiting rods 521 arranged in the second limiting groove. Since the second limiting part can be integrally formed with the first limiting part and the sleeve part as described above, the following description is made in combination with the drawings, taking the limiting part 50 as a whole.

[0056] The first gear 21 has a first limit position and a second limit position, and the two limit positions correspond to the two limit positions corresponding to the maximum angle of the door body 300 closing and the maximum angle of the door body 300 opening, respectively. A stop device can be installed between the door body 300 and the box body 200 to limit the maximum angle of the door body 300 rotating. Between the first limit position and the second limit position, the first gear 21 is always engaged with the second gear 30.

[0057] When the first gear 21 rotates between the first limit position and the second limit position, the support body 11 is always at least partially located in the second limiting groove, and at least part of the limiting rod 521 is always located in the first limiting groove 12. The support member and the limiting part 50 form a nested positional relationship. The limiting rod 521 of the limiting part 50 is constrained inside the first limiting groove 12 of the support member. The first limiting groove 12 constrains the limiting rod 521 to move only along the extension path of the groove. The support body 11 of the support member is also restricted inside the second limiting groove of the limiting part 50, which also plays a limiting role. Since the movement trajectory of the socket is arc-shaped in this embodiment, the second limiting groove restricts part of the movement of the support body 11. Thus, on the one hand, the movement path is more reliable and less prone to separation, and on the other hand, it plays a better supporting role for the limiting part 50.

[0058] The limiting part 50 includes a sleeve plate 51, a sliding groove 52 enclosed by the sleeve plate 51, and a plurality of openings 53 penetrating the sleeve plate 51. The sleeve plate 51 is sleeved on the outside of the support member through the sliding groove 52. A first rotating shaft 23 is provided coaxially at the axis of the first gear 21, and a second rotating shaft 31 is provided coaxially at the axis of the second gear 30. The first rotating shaft 23 and the second rotating shaft 31 pass through different openings 53 respectively.

[0059] The first rotating shaft 23 and the first gear 21 are coaxially arranged, meaning that the first rotating shaft 23 and the first gear 21 both rotate along the same axis. The second rotating shaft 31 and the second gear 30 are coaxially arranged, meaning that the second rotating shaft 31 and the second gear 30 both rotate along the same axis. The first rotating shaft 23 and the second rotating shaft 31 are both inside the opening 53 of the sleeve plate 51 of the limiting part 50, so that the axes of the first rotating shaft 23 and the second rotating shaft 31 are relatively fixed, and the first gear 21 and the second gear 30 are always meshed.

[0060] Furthermore, the first guide portion 40 includes a guide groove 41, the groove direction of which is set along a first preset trajectory; the second guide portion includes a guide rod, which is fixedly connected to the second gear 30 and inserted into the guide groove 41, such as... Figure 3 , 5 As shown in Figures 7 and 9, during the meshing and rotation of the second gear 30 with the first gear 21, the movement is also restricted by the guide groove 41. That is to say, the second rotating shaft 31 not only rotates but also moves in a plane perpendicular to the second rotating shaft 31. This movement is restricted by the guide groove 41 and the guide rod, as well as by the limiting relationship between the limiting rod 521 and the first limiting groove 12. In other words, the movement of the second gear 30 in the plane perpendicular to the second rotating shaft 31 is simultaneously restricted by the first preset trajectory and the second preset trajectory.

[0061] The box 200 comprises a side wall 201, since the present embodiment is applied to the embedded hinge device 100, the axis of rotation of the door body 300 is the axis of rotation of the first gear 21, that is, the axis of the first gear 21, in order to realize embedded installation and reduce the amount of the door body 300 extending out of the plane of the side wall 201 when rotating, the axis of the first gear 21 is in the vertical projection plane of the door body 300, as shown in Figure 7 If the door body 300 directly rotates, the door seal of the door body 300 will be pressed against the box 200, in order to avoid the interference between the door seal and the box 200, the door body 300 moves away from the box 200 while rotating.

[0062] Compared with the prior art, the present embodiment has the following beneficial effects:

[0063] The hinge device 100 of the refrigeration equipment realizes the rotation of the rotating part 20 along the second preset track while moving by the cooperation of the linkage part and the limiting part 50, by limiting the second preset track, when the door body 300 rotates outward to open, the door body 300 simultaneously moves towards the direction of the side wall 201 towards the box 200, that is, away from the object that may interfere, so as to ensure that the door body 300 is opened as safely as possible, and is suitable for occasions with higher embedded level requirements; and the embedded hinge device 100 can be more flat and smaller in size compared with the existing hinge, occupies less space, and has an attractive appearance while reducing the occupation of the space reserved for installing the hinge, and improves the volume utilization rate of the refrigeration equipment.
