Detailed Description

FIG. 1 is a schematic structural diagram of an inner container and a drawer of a refrigerator body according to an embodiment of the present invention; FIG. 2 is an exploded schematic view of the structure shown in FIG. 1; FIG. 3 is an exploded schematic view of the drawer and cover; FIG. 4 is a schematic view of a drawer construction; FIG. 5 is a schematic view of a portion of the cover plate; fig. 6 is a schematic view of the matching structure of the cover plate and the sealing ring.

As shown in fig. 1 to 4, an embodiment of the present invention provides a refrigerator. Fig. 1 illustrates a cabinet inner container 20, the cabinet inner container 20 defines a storage compartment 201, a drawer 10 is disposed in the storage compartment 201, and the drawer 10 is inserted into the storage compartment 201 in a manner of being pushed and pulled back and forth. The upper side of the drawer 10 is opened to facilitate access to food.

The cover 12 is fixed to the inner wall of the storage compartment 201 at the upper side of the drawer. For example, in fig. 2, the left side wall 22 and the right side wall 24 of the storage compartment 201 are provided with ribs 221, and the cover plate 12 is lapped on the two ribs 221. When the drawer 10 is pushed into the storage compartment 201, the cover 12 can seal the upper opening of the drawer 10.

The upper opening edge of the drawer 10 is protruded outward to form a sealing skirt 16 in a square frame shape, as shown in fig. 3 and 4. The left and right sides of the sealing skirt 16 are inclined downward from the front to the rear at a predetermined angle, which may be 5 to 10 °. The lower side periphery of the cover plate 12 is embedded with a sealing ring 17 matched with the sealing skirt 16, the left side and the right side of the sealing ring 17 are gradually inclined downwards from front to back, and the inclined angle is preferably equal to the inclined angle of the sealing skirt 16. During the backward movement of the drawer 10, the sealing skirt 16 is in sealing engagement with the sealing ring 17. Since the sealing skirt 16 and the gasket 17 are inclined downward from front to rear, the more the drawer is pushed rearward, the tighter the sealing skirt 16 and the gasket 17 are attached to each other.

As shown in fig. 5, the cover plate 12 includes a top plate 122, side plates 123 extending downward from both left and right sides of the top plate 122, and a rear plate 125 extending downward from a rear edge of the top plate 122, so that the cover plate 12 is formed in a housing shape. The inner sides of the two side plate portions 123, the inner side of the rear plate portion 125, and the front edge of the top plate portion 122 form a square frame-shaped groove 124 for accommodating the gasket 17. The sealing ring 14 is embedded in the receiving groove 124, please refer to fig. 6.

In the embodiment of the invention, a user does not need to manually operate the cover plate 12, sealing and unsealing of the drawer 10 are realized in the process of pushing and pulling the drawer 10, and the use is very convenient. And, a plurality of sets of cover plates 12 and drawers 10 may be provided in the storage compartment 201 of the refrigerator to form a plurality of storage spaces independent of each other, thereby facilitating the use of users. Therefore, the embodiment of the invention is particularly suitable for placing the drawer in a refrigerating chamber with larger space for use.

In some embodiments, as shown in fig. 2 to 4, the rollers 31 are respectively mounted on the front sides of the left and

right side walls

22 and 24 of the storage compartment 201, and the rollers 31 can rotate around their own axes. A first slide 32 extending forward and backward is provided behind the roller 31. The left and right side walls of the drawer 10 are respectively provided with a second slideway 13 extending forwards and backwards, the second slideway 13 is supported by the roller 31, the rear end of the first slideway 32 is provided with a slide block 15 protruding downwards, and the slide block 15 is arranged on the first slideway 32 in a way of sliding forwards and backwards.

During the pushing and pulling of the drawer 10, the roller 31 supports the second slideway 13 to form rolling friction, and the sliding block 15 slides on the first slideway 32 to form sliding friction. When the drawer 10 is pulled forward to the front limit position, the roller 31 can block the sliding block 15 from moving forward, so that the drawer 10 cannot move forward, and the drawer 10 is prevented from falling.

Compared with the scheme that the two sides of the drawer are directly lapped on the left side wall and the right side wall of the storage compartment in the existing structure, the drawer structure has smaller integral friction. Compare the slide rail scheme that current structure is complicated, simple structure, the cost is lower.

In some embodiments, the refrigerator further comprises at least one locking mechanism 80, the locking mechanism 80 being capable of locking the position of the drawer 10 when the drawer 10 is in the closed state.

FIG. 8 is a schematic view of the locking mechanism and acceleration mechanism with the drawer in an open condition; FIG. 9 is an enlarged view at A of FIG. 8; FIG. 10 is an enlarged view at B of FIG. 8; FIG. 11 is a schematic view of the locking mechanism and acceleration mechanism with the drawer in a closed position; FIG. 12 is an enlarged view at C of FIG. 11; FIG. 13 is an enlarged view at D of FIG. 12; fig. 14 is a schematic structural view of the translation block and the rotation block.

As shown in fig. 8 to 13, each locking mechanism 80 may generally include a pivoting catch 83, a catch 81, and a first resilient member. The pivotal latch 83 is pivotally disposed on the cover 12 about a left-right extending axis and has a front latch 835 and a rear latch 836 extending downward, the front latch 835 being located forward of the rear latch 836. The catch 81 is provided on the side wall of the drawer 10.

The number of the locking mechanisms 80 is preferably two, and the pivoting latches 83 of the two locking mechanisms 80 are respectively provided on the two side plate portions 123 of the cover plate 12. The catches 81 of the two locking mechanisms 80 are respectively provided on the left and right side walls of the drawer 10.

When the drawer 10 is in the closed position, as shown in fig. 13, the front latch 835 is captured between the front latch 835 and the rear latch 836 to lock the drawer 10 to the side wall 22 of the storage compartment 201 with the pivoting catch 83 in the first position.

With the pivoting catch 83 in the first position shown in fig. 13, the drawer 10 is pulled forward and the pivoting catch 83 pivots from the first position to the second position, i.e., clockwise from the state of fig. 13 to the state of fig. 10. That is, the catch 81 moves forward to push the front latch 835 to pivot forward and upward, so that the catch 81 is released from the position between the front latch 835 and the rear latch 836 to unlock the drawer 10. In the process, the first elastic member exerts a resisting moment on the pivoting latch 83, so that the user must overcome the resisting moment to pull the drawer 10 open, and the locking between the drawer 10 and the cover plate 12 is more stable.

When the pivoting latch 83 is in the second position shown in fig. 10, pushing the drawer 10 back to close, the catch 81 will first contact the rear latch 836 (at this time, the rear latch 836 is lower than the catch 81, and the catch 81 is lower than the front latch 835), causing the pivoting latch 83 to pivot to the first position, i.e., counterclockwise from the state of fig. 10 to the state of fig. 13, and causing the front latch 835 to move back downward to the first position, locking the drawer 10 to the cover 12. In the process, the first elastic element applies a resisting moment to the pivoting latch 83, so that a certain buffer is applied to the backward movement of the drawer 10, and the user experience is improved.

In the embodiment of the invention, the locking mechanism 80 can automatically lock and unlock the drawer 10 during the pushing and pulling process of the drawer 10, thereby facilitating the use of users.

In some embodiments, as shown in fig. 10 and 13, the first elastic element may be a torsion spring 85 having an axis extending in a left-right direction, and two ends of the torsion spring steel bar are respectively hinged to the lower end of the pivoting latch 83 (such that the hinged point is located below the pivoting shaft 831 of the pivoting latch 83) and the left side wall 22 of the storage compartment 201 (directly or indirectly hinged to the left side wall 22 of the storage compartment 201). When the pivotal latch 83 is at a critical position between the first position and the second position, the line of action of the pushing force F of the torsion spring 85 on the pivotal latch 83 passes through the pivot point of the pivotal latch 83, and in this state, the pushing force of the torsion spring 85 on the pivotal latch 83 has zero force arm, and the pivotal latch 83 is not rotated.

When the pivoting latch 83 is between the first position and the threshold position, as shown in fig. 13, the line of action of the (downward) urging force F of the torsion spring 85 against the pivoting latch 83 is located in front of the pivot point of the pivoting latch 83.

When the pivoting latch 83 is between the threshold position and the second position, as shown in fig. 10, the line of action of the (downward) urging force F of the torsion spring 85 against the pivoting latch 83 is located behind the pivot point of the pivoting latch 83.

Thus, during the opening process of the drawer 10, the pivoting latch 83 rotates counterclockwise, the torsion spring 85 first applies a resisting moment to the pivoting latch 83, which tends to rotate clockwise, so as to provide resistance to the user pulling the drawer 10 open, and after the pivoting latch 83 rotates past the critical position, the torsion spring 85 changes its moment direction, so that the pivoting latch 83 pivots to the second position shown in fig. 10 in an accelerated manner.

During the closing process of the drawer 10, the pivoting latch 83 rotates clockwise, the torsion spring 85 first applies a resisting moment to the pivoting latch 83, which tends to rotate counterclockwise, to cushion the closing of the drawer 10, and after the pivoting latch 83 rotates beyond a critical position, the torsion spring 85 changes its moment direction, so that the pivoting latch 83 pivots at an accelerated speed to the first position shown in fig. 13. It is confirmed by experiment that the force applied by the torsion spring 85 to the pivotal lock 83 is set to 20 ± 5N, so that the user can feel the best when pushing or pulling the drawer 10.

In some embodiments, the refrigerator includes two mounting plates 30, the two mounting plates 30 are detachably mounted on the left and

right side walls

22 and 24 of the storage compartment 201, the first slide rail 32 is formed on the mounting plate 30, and the roller 31 is mounted on the mounting plate 30.

In the embodiment of the invention, the locking mechanism 80 can automatically lock and unlock the drawer 10, thereby facilitating the use of users. Also, during the pivoting of the pivoting latch 83 from the second position to the first position (i.e., closing the drawer 10), the torsion spring 85 applies a resisting moment to the pivoting latch 83, i.e., a backward force to the catch 81, so that the drawer 10 can be stably locked and sealed. During the pivoting of the pivoting latch 83 from the first position to the second position (i.e., opening the drawer 10), the torsion spring 85 can apply a resisting moment to the pivoting latch 83 to cushion the closing process of the drawer 10 and prevent the pivoting latch from directly striking the rear wall of the storage compartment 201.

In some embodiments, the refrigerator further comprises at least one acceleration mechanism 40, wherein the acceleration mechanism 40 is configured to accelerate the drawer 10 when the drawer 10 moves backwards and triggers the movement thereof.

As shown in fig. 8 to 14, the number of the accelerating mechanisms 40 is preferably two, and each accelerating mechanism 40 includes a first guide groove 41 extending forward and backward, a second guide groove 42 in an L shape, a translation block 50 and a rotation block 60, a second elastic member 70, and a touch block 14. The first guide groove 41 is opened in the side plate portion 123 of the cover plate 12. The second guide groove 42 is also opened on the side plate portion 123 and located below the first guide groove 41, and has a front section as a vertical section 421 and a rear section as a horizontal section 422. The translation block 50 is hinged to the rotation block 60, the hinge shaft extends in the left-right direction and is slidably disposed in the first guide groove 41 and the second guide groove 42, and a clamping groove 63 is formed in the lower side of the rotation block 60. The second elastic element 70 is configured to apply a backward elastic pre-load force to the translational block 50, and the second elastic element 70 may be an extension spring, and the backward ends of the extension spring are respectively connected to the translational block 50 and the cover plate 12. The touch block 14 is provided at a side wall of the drawer 10.

As shown in fig. 14, the rotating block 60 has a rotating shaft 61, and the rotating shaft 61 is rotatably inserted into the mounting hole 52 of the translation block 50. The rotating block 60 has a guide post 62 thereon for insertion into the second guide groove 42.

When the drawer 10 is in the open state, the rotating block 60 is caught in the vertical section 421 of the second guide groove 42, as shown in fig. 9.

When the drawer 10 moves backwards (from fig. 9 to fig. 12), the touch block 14 pushes the rear wall 632 of the locking groove 63 backwards, so that the rotating block 60 rotates to be separated from the vertical section 421 of the second guide groove 42 and enter the horizontal section 422, the touch block 14 enters the locking groove, and the translation block 50 and the rotating block 60 move backwards under the action of the elastic pretightening force to drive the touch block 14 and the drawer 10 to move backwards under the action of the elastic pretightening force. The clamping tooth 836 is accelerated to automatically complete locking after the clamping piece 81 is impacted, the user does not need to push the drawer 10 forcibly, the operation of closing the drawer 10 is facilitated, and the user experience is improved.

In the process of moving the drawer 10 forward (from fig. 12 to fig. 9), when the touch block 14 drives the rotating block 60 to move forward to the bottom end of the vertical section 421 of the second guide slot 42, the front wall 631 of the engaging slot 63 is pushed to rotate the rotating block 60, and the vertical section 421 is engaged, so that the touch block 14 is disengaged from the engaging slot 63, and the drawer 10 continues to move forward to the open state.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
