Detailed Description
The present invention will be described in detail below with reference to the embodiments shown in the drawings, and in detail, reference is made to fig. 1-6, which illustrate preferred embodiments of the present invention, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. It should be understood that these embodiments are not intended to limit the present invention, and that functional, method, or structural equivalents and alternatives falling within the scope of the present invention may be modified by any person skilled in the art to include such embodiments.
Referring to fig. 1, the present invention provides a refrigerator, which includes a refrigerator body 1, a hinge plate 2 fixed on the refrigerator body 1, and a door body 3 rotatably connected to the hinge plate 2. One of the hinge plate 2 and the door body 3 is provided with a hinge shaft 21, the other is provided with a long shaft hole 31 matched with the hinge shaft 21, and the door body 3 is rotatably connected to the hinge plate 2 through the matching between the hinge shaft 21 and the long shaft hole 31.
As shown in connection with fig. 3, the door body 3 includes a front wall 32, a hinge mounting side 33, and a pivot end 34. In the invention, the refrigerator is taken as an embedded refrigerator for specific explanation. The front wall 32 of the door 3 is the side of the refrigerator facing the external environment when it is inserted into the cabinet 4. The hinge mounting side 33 of the door body 3 is the upper side of the door body 3, i.e. one end of the hinge plate 2 is mounted on the hinge mounting side 33, and the other end of the hinge plate 2 is mounted on the case 1. The pivoting end 34 of the door 3 is the end of the door 3 that rotates about the housing 1.
Only the cabinet 4 on one side of the pivoting end 34 is shown. In actual installation, the refrigerator is wholly embedded in the cabinet 4. It will be appreciated that the refrigerator need not be embedded in the cabinet 4, but may be embedded in a wall, or the refrigerator may be a non-embedded refrigerator.
A direction defining a center of the door body 3 in a closed state toward the pivoting end 34 of the door body 3 is a first direction, and a direction opposite to the first direction is a second direction.
Specifically, when the hinge plate 2 is disposed on the right side of the refrigerator, the first direction is a left-to-right direction, and the second direction is a right-to-left direction. When the hinge plate 2 is disposed on the left side of the refrigerator, the first direction is a right-to-left direction, and the second direction is a left-to-right direction.
Specifically, the long shaft hole 31 has opposite first and second ends 311, 312, and the hinge shaft 21 is located at the first end 311 when the door 3 is in the closed state. That is, in the process of opening and closing the door body 3, the hinge shaft 21 is switched between the first end 311 and the second end 312 with respect to the long shaft hole 31, so that the door body 3 can be translated in a predetermined direction, and the door body 3 can be moved along a predetermined track.
In the following, the hinge plate 2 is taken as an example in which the hinge shaft 21 is disposed on the hinge plate 2, and the long shaft hole 31 is disposed on the door body 3, it is understood that the position of the hinge shaft 21 is not changed during the opening and closing of the door body 3, and the long shaft hole 31 moves along with the door body 3, so that the long shaft hole 31 moves relative to the hinge shaft 21, so that the hinge shaft 21 is switched between the first end 311 and the second end 312. Of course, the hinge shaft 21 may be provided on the door body 3 in other embodiments, and the long shaft hole 31 may be provided on the hinge plate 2.
Further, the refrigerator further includes a magnetic driving assembly 5 disposed on the same side as the long shaft hole 31, and the magnetic driving assembly 5 acts on the hinge shaft 21 to drive the hinge shaft 21 and the long shaft hole 31 to move relatively, so as to translate the door body 3. According to the refrigerator disclosed by the invention, the magnetic driving assembly 5 is arranged to drive the door body 3 to translate, the structure of the hinge plate 2 is not required to be changed, the structure is simple, the implementation is easy, and the movement track of the door body 3 in the process of opening and closing the door body 3 can be controlled according to specific requirements, so that the refrigerator is suitable for a plurality of scenes, such as embedded scenes.
It should be understood that, the arrangement on the same side as the long shaft hole 31 means that the long shaft hole 31 and the magnetic driving assembly 5 are simultaneously arranged on the door body 3 or on the hinge plate 2, so that the magnetic driving assembly 5 can act on the hinge shaft 21 to enable the hinge shaft 21 and the long shaft hole 31 to move relatively.
In the present embodiment, the long shaft hole 31 is provided in the door body 3, and the magnetic driving unit 5 is provided in the door body 3.
Specifically, as shown in fig. 4-5, the magnetic driving assembly 5 is configured to drive the hinge shaft 21 to move from the first end 311 to the second end 312 during the process that the door 3 is continuously opened from the first preset angle to the second preset angle.
In one embodiment, the long shaft hole 31 extends along the thickness direction of the door body 3, and the second end 312 is located on a side of the first end 311 away from the front wall 32 of the door body 3, that is, on a front side of the first end 311. When the opening angle of the door body 3 is between 0 ° and 90 °, the included angle between the extending direction of the long shaft hole 31 and the first direction is gradually reduced, so that when the opening angle of the door body 3 is between 0 ° and 90 °, the door body 3 translates to move the hinge shaft 21 from the first end 311 to the second end 312, and the door body 3 moves away from the case 1 while moving toward the first direction. On the one hand, the door body 3 is far away from the box body 1 along the first direction, so that the door body 3 is far away from the box body 1 towards the first direction as far as possible, the opening degree of the door body 3 is ensured, the door body 3 is prevented from shielding a storage compartment in the box body 1 or a drawer in the box body 1 and the like from being interfered by the door body 3 to be opened, and a user is facilitated to take and put articles; on the other hand, the door 3 moves away from the case 1, increasing the distance between the door 3 and the case 1, preventing interference between the rear wall of the door 3 and the case 1 during opening of the door 3, and, for an embedded refrigerator, enabling the front wall 32 of the door 3 to protrude forward from the front end of the cabinet 4 at one end of the pivoting end 34, reducing interference between the door 3 and the cabinet 4 during rotation of the door 3. Of course, it is not limited thereto, and it is understood that the extending direction of the long shaft hole 31 may be adjusted according to specific requirements to control the translation direction of the door body 3.
In one embodiment, the second preset angle is 90 °. Of course, this is not a limitation. That is, in the process that the door body 3 is opened from the first preset angle to the second preset angle, the motion track of the door body 3 is: the door 3 moves in the first direction and moves in a direction away from the case 1.
Specifically, the door body 3 has a mounting cavity therein, which is in communication with a side of the long shaft hole 31 away from the hinge plate 2, the magnetic driving assembly 5 is mounted in the mounting cavity, and is connected to the hinge shaft 21 from the side of the long shaft hole 31 away from the hinge plate 2. So that the magnetic driving component 5 can act on the hinge shaft 21 to drive the hinge shaft 21 and the long shaft hole 31 to move relatively.
In one embodiment, the magnetic driving assembly 5 includes an electromagnet 51 fixedly disposed in the mounting cavity, a magnetic core 52 movably connected to the electromagnet 51, and a limiting plate 53 connected to the magnetic core 52, where the hinge shaft 21 is in limiting connection with the limiting plate 53, so that the hinge shaft 21 and the limiting plate 53 move synchronously. When the electromagnet 51 is in the energized state, the electromagnet 51 attracts the magnetic core 52, the magnetic core 52 moves in opposite directions with the electromagnet 51, the limiting plate 53 is driven to move in opposite directions with the electromagnet 51, the limiting plate 53 acts on the hinge shaft 21, so that the hinge shaft 21 moves toward the second end 312 relative to the long shaft hole 31, and the door 3 is driven to translate simultaneously in the rotating process.
Further, the electromagnet 51 has a guide slot 511 matching with the magnetic core 52, and the magnetic core 52 is movably connected in the guide slot 511, so as to limit the relative movement direction of the magnetic core 52 and the electromagnet 51, enhance the stability of the magnetic driving assembly 5, and enhance the translational stability of the door body 3.
Further, as shown in connection with fig. 3-4 and fig. 5-6, the magnetic drive assembly 5 is further configured to: when the door 3 is opened from the closed state to a first predetermined angle, the magnetic driving assembly 5 maintains the hinge shaft 21 at the first end 311, so that the door 3 is rotated in place by the first predetermined angle. In the process that the door body 3 is continuously opened from the second preset angle to the third preset angle, the magnetic driving assembly 5 drives the hinge shaft 21 to reset from the second end 312 to the first end 311 relative to the long shaft hole 31, so that the door body 3 moves towards the second direction, and the opening of the door body 3 is further increased until the door body 3 is opened to the third preset angle, so that a user can conveniently take and put articles. Of course, this is not a limitation.
It is known that when the door body 3 is in a closed state, the door seal on the door body 3 is tightly adsorbed on the box body 1, so that when the door body 3 is opened in a self-closing state, the door body 3 is firstly rotated in situ by a first preset angle, and the door seal can be firstly separated from the box body 1, so that deformation and damage of the door seal are prevented, and the subsequent sealing performance of the door body 3 is affected. Correspondingly, in the final stage of closing the door, the door body 3 rotates in situ to be closed, so that the deformation of the door seal can be reduced, and the smooth closing of the door body 3 is facilitated.
Meanwhile, for the refrigerator with the turnover beam, the door body 3 rotates in situ when being opened from the closed state, so that the turnover beam can turn over and separate from the guide structure on the refrigerator body 1, and the subsequent door body 3 can be opened continuously in a rotating way. Correspondingly, in the process from the closing to the final stage, the door body 3 rotates to the closing in situ, and the overturning beam can overturn to cover the gap between the left door body 3 and the right door body 3 under the guidance of the guide structure on the box body 1.
In one embodiment, the first preset angle is between 30 ° and 60 °. Of course, this is not a limitation.
In an embodiment, referring to fig. 2, the magnetic driving assembly 5 further includes an elastic member 54 disposed in the guide slot 511, and the magnetic core 52 is connected to the elastic member 54. In the process of opening the door body 3 from the closed state to the first preset angle, the electromagnet 51 is in the power-off state, and at this time, the hinge shaft 21 is limited at the first end 311 under the action of the elastic force of the elastic member 54, so that the door body 3 rotates in place. In the process that the door body 3 is opened from the first preset angle to the second preset angle, the electromagnet 51 is in an energized state, the electromagnet 51 attracts the magnetic core 52, the magnetic core 52 moves relatively to the electromagnet 51 to compress the elastic member 54, and the elastic member 54 is in a compressed state at this time, so that in the process that the door body 3 is opened from the second preset angle to the third preset angle, the electromagnet 51 is in a de-energized state, and under the action of elastic restoring force of the elastic member 54, the hinge shaft 21 returns to the first end 311 from the second end 312 to enable the door body 3 to move in the second direction. Of course, the present invention is not limited thereto, and in other embodiments, the elastic member 54 may be omitted, and the moving track of the door body 3 may be controlled by controlling the repulsion and attraction between the electromagnet 51 and the magnetic core 52, that is, controlling the electromagnet 51 and the magnetic core 52 to repel each other, so as to limit the movement of the hinge shaft 21 at the first end 311 along the long axis hole 31 and drive the hinge shaft 21 at the second end 312 to move toward the first end 311 relative to the long axis hole 31.
The elastic member 54 may be a spring, and has a simple structure and good stability. Of course, this is not a limitation.
Further, referring to fig. 3 to 6, the refrigerator further includes a stop rib 22 disposed on the same side as the hinge shaft 21, and a positioning slot 35 disposed on the same side as the long shaft hole 31 and engaged with the stop rib 22. The positioning groove 35 limits the movement of the stop rib 22, so that the movement speed of the hinge shaft 21 relative to the long shaft hole 31 can be limited, the hinge shaft 21 and the long shaft hole 31 can move relatively slowly, the movement stability of the door body 3 is enhanced, the collision between the hinge shaft 21 and the long shaft hole 31 can be reduced, the damage is prevented, and the noise is reduced.
Specifically, the stop rib 22 is in an arc shape concentric with the hinge shaft 21. And the stopper rib 22 is spaced apart from the hinge shaft 21.
It will be appreciated that the distance between the stop rib 22 and the hinge shaft 21 is constant, and the position of the hinge shaft 21 can be limited by limiting the position of the stop rib 22. And the stop rib 22 is arc-shaped, so that when the stop rib 22 is positioned in the groove section matched with the shape of the stop rib, the stop rib 22 cannot shake, thereby limiting the shaking of the hinge shaft 21 and enhancing the stability of the movement of the door body 3.
Specifically, the positioning slot 35 has a first slot section 351, a second slot section 352, and a transition slot section 353 connecting the first slot section 351 and the second slot section 352, and the distance between the stop rib 22 and the hinge shaft 21 is fixed, so that the distance between the first slot section 351 and the first end 311 is equal to the distance between the second slot section 352 and the second end 312, and the first slot section 351 is closer to the first end 311 than the second slot section 352.
When the door body 3 is in a closed state or is opened from the closed state to a first preset angle, the hinge shaft 21 is located at the first end 311, and the stop rib 22 is located in the first slot section 351 and moves to an interface section between the first slot section 351 and the transition slot section 353. In the process of opening the door body 3 from the first preset angle to the second preset angle, the hinge shaft 21 moves toward the second end 312 relative to the long shaft hole 31, at this time, the stop rib 22 moves from the junction section to the second slot section 352 through the transition slot section 353, and when the hinge shaft 21 is located at the second end 312, the stop rib 22 is located in the second slot section 352.
