Description

Sealing assembly for push-and-play drawer and storage container

Technical Field

The utility model relates to the technical field of storage containers, in particular to a sealing assembly for a push-and-pull drawer and a storage container.

Background

The push-spring type drawer is used as a special drawer structure, and a push-spring part is arranged between the drawer and a part for accommodating the drawer. When the drawer needs to be closed, the drawer needs to be pushed to an extreme position against the elastic force of the pushing and elastic component. Then, the user stops applying force, and the drawer rebounds for a small distance under the action of the elasticity of the pushing and bouncing part, so that locking is finished. When the drawer needs to be opened, the drawer needs to be pressed backwards, so that the drawer moves backwards for a certain distance, and the push elastic component is unlocked. Then, the user stops applying force, and the pushing and ejecting component ejects the drawer.

Currently, some refrigerators also begin to employ push-and-pop drawers to enhance the user's experience. However, since the refrigerator is a special home appliance for refrigerating foods, sealability of a storage space is very important. For a push-and-spring drawer, each time the drawer is opened and closed, a certain distance is needed to be pressed on the basis of the closed position, so that the sealing strip between the drawer and a compartment containing the drawer is frequently compressed too much, and the sealing strip cannot return to lose the sealing effect.

In another aspect of the present utility model, there is also provided a storage container including:

the outer barrel is provided with a containing cavity and an inlet communicated with the containing cavity;

the drawer is arranged in the accommodating cavity in a drawable manner through the placement opening;

According to the sealing assembly, the annular cavity and the annular opening are formed in the annular sealing frame, so that the annular sealing ribs can be embedded into the annular cavity along the drawing direction of the drawer through the annular opening. And because the thickness of the annular sealing rib is larger than the width of the annular opening, the solid parts of the annular sealing frames at two sides of the annular opening can be extruded in the process of embedding the annular sealing rib into the annular cavity. And then, the solid parts of the annular sealing frames at the two sides of the annular opening are respectively tightly attached to the inner annular surface and the outer annular surface of the annular sealing rib, so that sealing is formed between the annular sealing frames and the annular sealing ribs. And because the depth of the annular cavity is larger than the length of the annular sealing rib embedded in the annular cavity, the annular sealing rib can be further embedded into the annular cavity for a certain distance on the basis of the embedded position of the drawer in the closed state. Thereby giving the push-spring drawer additional pressing distance when opening and closing. Therefore, the sealing assembly ensures that the sealing contact surface is not opposite to the drawing direction of the drawer on the basis of ensuring the sealing effect of the push-and-pull type drawer. Therefore, the sealing contact surface is not excessively compressed when the drawer is moved by an additional pressing distance, that is, the sealing member is not excessively compressed. Thereby avoiding the occurrence of the situation that the sealing effect is lost due to frequent over-compression of the sealing component. Thereby enabling the push-spring drawer to be better used in a refrigerator.

Further, the seal assembly of the present utility model enables a pit-like structure to be formed between the first inclined portion and the second inclined portion and enables an annular opening to be formed at the pit bottom of the pit-like structure by providing the first inclined portion at the first forming portion and providing the second inclined portion at the second forming portion. Thus, the annular sealing bead is in sealing contact with the first and second inclined portions during insertion of the annular sealing bead into the annular cavity. Because the initial states of the first inclined part and the second inclined part are inclined, compared with the structure mode that the solid parts at the two sides of the annular opening are perpendicular to the embedding direction of the annular sealing rib, the first inclined part and the second inclined part are easier to deform to enable the first inclined part and the second inclined part to be horizontal after being extruded by the annular sealing rib. That is, the first inclined portion and the second inclined portion are structured to help increase the contact area with the annular seal bead, thereby improving the sealing effect.

Still further, the seal assembly of the present utility model is provided with the second inclined portion and the fourth inclined portion at the second forming portion by providing the straight arm portion at the annular seal frame and providing the first inclined portion and the third inclined portion at the first forming portion. The first inclined portion and the third inclined portion form a peak-like structure, and the second inclined portion and the fourth inclined portion form a peak-like structure. That is, the first forming portion has two deformation folding points, namely, a junction of the third inclined portion and the outer annular wall, and a junction of the first inclined portion and the third inclined portion. The second forming part is provided with two deformation folding points, namely a connecting part of the fourth inclined part and the inner annular wall and a connecting part of the second inclined part and the fourth inclined part. Thus, the annular sealing bead is in sealing contact with the first and second inclined portions during insertion of the annular sealing bead into the annular cavity. And because both the first formation and the second formation have two inflection points. Therefore, the first inclined portion and the second inclined portion are liable to deform the first formed portion and the second formed portion at the deformation node after being pressed by the annular seal rib. That is, the peak-like structure formed by the first inclined portion and the third inclined portion and the peak-like structure formed by the second inclined portion and the fourth inclined portion are brought close to each other, so that the contact area between the first inclined portion, the second inclined portion and the annular seal rib can be further increased, and the sealing effect can be further improved.

The above, as well as additional objectives, advantages, and features of the present utility model will become apparent to those skilled in the art from the following detailed description of a specific embodiment of the present utility model when read in conjunction with the accompanying drawings.

As shown in fig. 1-3, in one embodiment, the seal assembly includes an annular seal frame 100 and an annular seal bead 200. The annular sealing frame 100 is formed with an annular cavity 101, the annular cavity 101 having an annular opening 102. The annular sealing rib 200 is inserted into the annular cavity 101 through the annular opening 102 in the drawing direction of the drawer. The thickness of the annular sealing bead 20 is greater than the width of the annular opening 102. And, in the closed state of the drawer, the depth of the annular cavity 101 is greater than the length of the annular sealing rib 200 embedded in the annular cavity 101.

Referring to fig. 1 to 3, in particular, an annular sealing frame 100 and an annular sealing rib 200 may be provided at openings of a drawer and a receiving chamber for receiving the drawer, respectively. So that the drawer is in a closed state, i.e., retracted into the receiving chamber, the annular sealing rib 200 and the annular sealing frame 100 can be fitted together to form a seal. That is, the annular sealing rib 200 and the annular sealing frame 100 can be fitted together in the drawing direction of the drawer.

With continued reference to fig. 1-3, an annular cavity 101 is formed within the annular sealing frame 100, and an annular opening 102 is formed on the side of the annular cavity 101 that mates with the annular sealing bead 200. The annular seal rib 200 has an annular plate shape. The thickness of the annular sealing bead 200, i.e., the distance between the inner annular surface and the outer annular surface, and the width of the annular opening 102, i.e., the distance between the two annular edges of the annular opening 102.

During closing of the drawer, the annular sealing bead 200 continues to approach the annular sealing frame 100 until it reaches the annular opening 102 of the annular sealing frame 100. Then, as the drawer moves, the annular sealing bead 200 is inserted into the annular cavity 101 through the annular opening 102.

Since the thickness of the annular seal bead 200 is greater than the width of the annular opening 102, the annular seal bead 200 presses the solid portions of the annular seal frame 100 on both sides of the annular opening 102 during the insertion of the annular seal bead 200 into the annular cavity 101. Then, the solid portions of the annular sealing frame 100 at both sides of the annular opening 102 are respectively tightly attached to the inner annular surface and the outer annular surface of the annular sealing rib 200, so that a seal is formed between the annular sealing frame 100 and the annular sealing rib 200.

The depth of the annular cavity 101 is greater than the length of the annular sealing rib 200 embedded in the annular cavity 101 when the drawer is in the closed state, i.e., after the drawer is stable. That is, the annular sealing bead 200 can also continue to embed a distance within the annular cavity 101. Thereby giving the push-spring drawer additional pressing distance when opening and closing.

In the solution of the present embodiment, by providing the annular cavity 101 and the annular opening 102 in the annular seal frame 100, the annular seal bead 200 can be inserted into the annular cavity 101 through the annular opening 102 in the drawing direction of the drawer. Since the thickness of the annular seal bead 200 is greater than the width of the annular opening 102, the solid portions of the annular seal frame 100 on both sides of the annular opening 102 are pressed during the insertion of the annular seal bead 200 into the annular cavity 101. Then, the solid portions of the annular sealing frame 100 at both sides of the annular opening 102 are respectively tightly attached to the inner annular surface and the outer annular surface of the annular sealing rib 200, so that a seal is formed between the annular sealing frame 100 and the annular sealing rib 200. Further, since the depth of the annular cavity 101 is greater than the length of the annular seal rib 200 embedded in the annular cavity 101, the annular seal rib 200 can be further embedded into the annular cavity 101 by a certain distance based on the embedded position in the drawer closed state. Thereby giving the push-spring drawer additional pressing distance when opening and closing.

Therefore, the sealing assembly of the embodiment ensures that the sealing contact surface is not opposite to the drawing direction of the drawer on the basis of ensuring the sealing effect of the push-and-pull type drawer. Therefore, for the case of sealing and for the case of an additional pressing distance of the drawer movement, there is mainly friction between the sealing members, and an excessive elastic force is not generated. Therefore, the seal contact surface is not excessively compressed, that is, the seal member is not excessively compressed. Thereby avoiding the occurrence of the situation that the sealing effect is lost due to frequent over-compression of the sealing component.

The annular seal frame 100 and the annular seal rib 200 may be square annular as shown in the drawings, or may be other annular as long as they can surround the opening of the accommodating chamber accommodating the drawer.

As shown in fig. 1 and 4, the annular seal frame 100 includes a first forming portion 110 and a second forming portion 120. The first forming portion 110 has a first inclined portion 111, and the first inclined portion 111 is inclined from front to back in the front-rear direction of the annular seal frame 100 and toward the direction approaching the second forming portion 120. The second forming portion 120 has a second inclined portion 121, and the second inclined portion 121 is inclined from front to back in the front-rear direction of the annular seal frame 100 and in a direction approaching the first forming portion 110. The annular opening 102 is formed between the first inclined portion 111 and the second inclined portion 121.

Referring to fig. 1 and 4, specifically, the first forming portion 110 and the second forming portion 120 are solid portions of the annular seal frame 100 on both sides of the annular opening 102. The front-rear direction of the annular seal frame 100, i.e., the insertion direction of the annular seal rib 200. That is, the action of the annular seal bead 200 being fitted into the annular chamber 101 is to move from front to back in the front-rear direction of the annular seal frame 100.

Accordingly, the first inclined portion 111 is inclined from front to back in the front-rear direction of the annular seal frame 100, and toward the second forming portion 120. The second inclined portion 121 is inclined from front to back in the front-rear direction of the annular seal frame 100 and toward the first forming portion 110. That is, a pit-like structure is formed between the first inclined portion 111 and the second inclined portion 121. The annular opening 102 is formed in the pit bottom of the pit-type structure.

In the aspect of the present embodiment, by providing the first inclined portion 111 at the first forming portion 110 and providing the second inclined portion 121 at the second forming portion 120, a pit-type structure can be formed between the first inclined portion 111 and the second inclined portion 121, and the annular opening 102 can be formed at the pit bottom of the pit-type structure.

Thus, during the embedding of the annular sealing bead 200 into the annular cavity 101, the annular sealing bead 200 is brought into sealing contact with the first inclined portion 111 and the second inclined portion 121. Because the first inclined portion 111 and the second inclined portion 121 are inclined in the initial state, the first inclined portion 111 and the second inclined portion 121 are more likely to deform to level themselves after being pressed by the annular seal rib 200 than in a structure in which the solid portions on both sides of the annular opening 102 are perpendicular to the embedding direction of the annular seal rib 200. That is, the first inclined portion 111 and the second inclined portion 121 are structured to help increase the contact area with the annular bead 200, thereby improving the sealing effect.

The solid portions on both sides of the annular opening 102 may be perpendicular to the insertion direction of the annular seal rib 200.

As shown in fig. 1 and 4, the annular sealing frame 100 further comprises a straight arm portion 130, the straight arm portion 130 comprising an outer annular wall 131, an inner annular wall 132 and a rear wall 133 of the annular cavity 101. The first forming portion 110 further includes a third inclined portion 112. The third inclined portion 112 has one end connected to the outer annular wall 131 and one end inclined in a direction away from the rear wall 133 toward the second forming portion 120. One end of the first inclined portion 111 is connected to the third inclined portion 112. The second forming part 120 further includes a fourth inclined part 122. The fourth inclined portion 122 has one end connected to the inner annular wall 132 and one end inclined in a direction away from the rear wall 133 toward the first forming portion 110. One end of the second inclined portion 121 is connected to the fourth inclined portion 122.

Referring to fig. 1 and 4, in particular, with reference to the top portion of the annular sealing frame 100 during use, the annular cavity 101 can be said to be surrounded by four cavity walls, namely a front wall, a rear wall 133, an inner annular wall 132 and an outer annular wall 131. The front wall forms part of the annular opening 102. The outer annular wall 131 and the inner annular wall 132 are portions parallel to the insertion direction of the annular seal bead 200. The rear wall 133 is the portion opposite the annular opening 102, in other words, the distance between the rear wall 133 and the annular opening 102 is the depth of the annular cavity 101.

Wherein the outer annular wall 131, the inner annular wall 132 and the rear wall 133 constitute the straight arm portion 130. In terms of the cross section of the straight arm portion 130, the straight arm portion 130 may be said to have a square frame structure with one surface removed. The front wall is composed of a first forming portion 110 and a second forming portion 120. And because the front wall is provided with the annular opening 102, the first forming portion 110 and the second forming portion 120 are not in contact with each other.

With continued reference to fig. 1 and 4, the third inclined portion 112 has one end connected to the outer annular wall 131 and one end inclined in a direction away from the rear wall 133 toward the second forming portion 120. One end of the first inclined portion 111 is connected to the third inclined portion 112.

Specifically, the third inclined portion 112 is inclined from the rear to the front in the front-rear direction of the annular seal frame 100, starting from the junction with the outer annular wall 131, and is inclined in a direction approaching the second forming portion 120. The first inclined portion 111 is inclined from front to back in the front-rear direction of the annular seal frame 100 and toward the second forming portion 120 with a connection point with the third inclined portion 112 as a starting point. That is, the first inclined portion 111 and the third inclined portion 112 form a peak-type structure. The peak faces forward of the annular seal frame 100.

The fourth inclined portion 122 has one end connected to the inner annular wall 132 and one end inclined in a direction away from the rear wall 133 toward the first forming portion 110. One end of the second inclined portion 121 is connected to the fourth inclined portion 122.

Specifically, the fourth inclined portion 122 is inclined from the rear to the front in the front-rear direction of the annular seal frame 100, starting from the connection with the inner annular wall 132, and is inclined in a direction approaching the first forming portion 110. The second inclined portion 121 is inclined from front to back in the front-rear direction of the annular seal frame 100 and in a direction approaching the first forming portion 110, starting from a connection point with the fourth inclined portion 122. That is, the second inclined portion 121 and the fourth inclined portion 122 form a peak-like structure. The peak faces forward of the annular seal frame 100.

In the aspect of the present embodiment, by providing the straight arm portion 130 at the annular seal frame 100, and providing the first inclined portion 111 and the third inclined portion 112 at the first forming portion 110, the second inclined portion 121 and the fourth inclined portion 122 are provided at the second forming portion 120. The first inclined portion 111 and the third inclined portion 112 form a peak-like structure, and the second inclined portion 121 and the fourth inclined portion 122 form a peak-like structure.

That is, the first forming portion 110 has two deformation folding points, namely, a junction of the third inclined portion 112 and the outer circumferential wall 131, and a junction of the first inclined portion 111 and the third inclined portion 112. The second forming portion 120 has two deformation folding points, namely, a junction of the fourth inclined portion 122 and the inner annular wall 132, and a junction of the second inclined portion 121 and the fourth inclined portion 122.

Thus, during the embedding of the annular sealing bead 200 into the annular cavity 101, the annular sealing bead 200 is brought into sealing contact with the first inclined portion 111 and the second inclined portion 121. And because both the first forming portion 110 and the second forming portion 120 have two inflection points. Therefore, the first and second

inclined portions

111 and 121 easily deform the first and second forming

portions

110 and 120 at the deformation nodes after being pressed by the annular bead 200.

That is, the peak-like structure formed by the first inclined portion 111 and the third inclined portion 112 and the peak-like structure formed by the second inclined portion 121 and the fourth inclined portion 122 are brought close to each other, thereby contributing to further increasing the contact area between the first inclined portion 111, the second inclined portion 121 and the annular seal rib 200, and further improving the sealing effect.

Referring to fig. 4, it is preferable that an initial angle at which the first inclined portion 111 and the third inclined portion 112 are connected is 90 degrees or more, and an initial angle at which the second inclined portion 121 and the fourth inclined portion 122 are connected is 90 degrees or more. By making the initial angle of the junction of the first inclined portion 111 and the third inclined portion 112 equal to or greater than 90 degrees, the initial angle of the junction of the second inclined portion 121 and the fourth inclined portion 122 equal to or greater than 90 degrees, it is facilitated to ensure that the peak-like structure formed by the first inclined portion 111 and the third inclined portion 112 and the peak-like structure formed by the second inclined portion 121 and the fourth inclined portion 122 have a sufficient deformation margin.

Referring to fig. 3 and 4, it is preferable that the thickness of the annular bead 200 is equal to the width of the straight arm portion 130 multiplied by the absolute value of tan (the initial angle where the first inclined portion 111 and the third inclined portion 112 are connected).

As shown in fig. 3 and 4, it is preferable that the initial angle at which the first inclined portion 111 and the third inclined portion 112 are connected, and the initial angle at which the second inclined portion 121 and the fourth inclined portion 122 are connected are all obtuse angles, and the annular seal rib 200 embedded in the annular chamber 101 makes the angle at which the first inclined portion 111 and the third inclined portion 112 are connected, and the clip angle at which the second inclined portion 121 and the fourth inclined portion 122 are connected become acute angles.

For example, the initial angle at the connection of the first inclined portion 111 and the third inclined portion 112 and the initial angle at the connection of the second inclined portion 121 and the fourth inclined portion 122 are 170 degrees, and the annular seal rib 200 embedded in the annular cavity 101 makes the angle at the connection of the first inclined portion 111 and the third inclined portion 112 and the angle at the connection of the second inclined portion 121 and the fourth inclined portion 122 become 30 degrees.

Referring back to fig. 1, the annular sealing frame 100 is provided with an engagement member 140. The engaging member 140 is provided on an outer side wall of an end of the annular sealing frame 100 opposite to the annular opening 102, and the engaging member 140 is used to mount the annular sealing frame 100 on a receiving chamber that receives a drawer or on a drawer.

Specifically, the cross-sectional shape of the engaging member 140 is such that the engaging member 140 has a rod-like structure with its end portion expanded to form a ship-anchored structure. The expanded portion of the snap 140 may engage the walls of the snap to form a secure fit in the mating snap. The engagement member 140 facilitates the installation of the annular sealing frame 100.

As shown in fig. 1 to 6, in one embodiment, the storage container includes an outer tub 10, a drawer 20, and a seal assembly in any of the above embodiments. The outer tub 10 is formed with a receiving chamber 11 and an insertion port communicating with the receiving chamber 11. The drawer 20 is drawably provided in the accommodating chamber 11 through the insertion opening. Drawer 20 is a push-spring drawer. The annular sealing frame 100 and the annular sealing rib 200 are mounted on the tub 10 and the drawer 20, respectively. The storage container is for being assembled in a refrigerator.

As shown in fig. 1 to 6, in particular, the outer tub 10 is substantially square, and the insertion port is formed on one side of the square. The annular sealing frame 100 is disposed at an end surface of the outer tub 10 for enclosing the insertion opening, that is, the annular sealing frame 100 is disposed around the insertion opening. An annular sealing rib 200 is provided on the inner surface of the front wall of the drawer 20. During the closing of the drawer 20, the annular sealing bead 200 continues to approach the annular sealing frame 100 until it reaches the annular opening 102 of the annular sealing frame 100. Then, as the drawer moves, the annular sealing bead 200 is inserted into the annular cavity 101 through the annular opening 102.

The depth of the annular cavity 101 is greater than the length of the annular sealing rib 200 embedded in the annular cavity 101 in the closed condition of the drawer 20, i.e. after the drawer 20 has been retracted into the receiving chamber 11 and stabilized. That is, the annular sealing bead 200 can also continue to embed a distance within the annular cavity 101. So that the drawer 20 can be continuously pressed for a distance to open the drawer.

In the solution of the present embodiment, the annular sealing frame 100 is provided with an annular cavity 101 and an annular opening 102 by installing the annular sealing frame 100 and the annular sealing rib 200 in the tub 10 and the drawer 20, respectively. So that the annular sealing rib 200 can be inserted into the annular cavity 101 through the annular opening 102 in the drawing direction of the drawer, the annular sealing rib 200 presses the solid portions of the annular sealing frame 100 at both sides of the annular opening 102. So that the solid portions of the annular sealing frame 100 on both sides of the annular opening 102 form a seal with the annular sealing rib 200.

Further, since the depth of the annular cavity 101 is greater than the length of the annular seal bead 200 that is inserted into the annular cavity 101, the annular seal bead 200 can be inserted a distance into the annular cavity 101 further based on the insertion position of the drawer 20 in the closed state. Thereby giving the push-spring drawer additional pressing distance when opening and closing.

Thus, a good seal is formed for the storage container. Moreover, the sealing contact surface is not excessively compressed when the drawer is moved by an additional pressing distance, that is, the sealing member is not excessively compressed. Thereby avoiding the occurrence of the situation that the sealing effect is lost due to frequent over-compression of the sealing component.

Moreover, the storage container is of an independent structure, can be assembled in the refrigerator body after the refrigerator body is manufactured, and is convenient and quick to manufacture and maintain subsequently.

As shown in fig. 6 and 7, the storage container further comprises a magnetic field device 30. The magnetic field device 30 is flat. A magnetic field device 30 is provided at the inner wall of the outer tub 10, the magnetic field device 30 being used to apply a magnetic field inside the drawer 20 retracted inside the outer tub 10.

Referring to fig. 6 and 7, in particular, the magnetic field device 30 includes a magnetic field generating member 31 and a magnetically conductive sheet 32. The magnetic field generating member 31 is for generating a magnetic field. The magnetic sheet 32 is disposed in close contact with the magnetic field generating member 31, and the area of the surface of the magnetic sheet 32 facing the magnetic field generating member 31 is larger than the area occupied by the magnetic field generating member 31.

Specifically, the magnetic field generating member 31 is an electric coil. The electrical coil is attached to the side of the magnetically permeable sheet 32 facing the drawer 20. The energized electrical coil produces a magnetic field that is guided by the magnetically permeable sheet 32 so that the magnetic field is more evenly distributed within the drawer 20.

In the solution of the present embodiment, the magnetic field means 30 are provided inside the outer tub 10. So that the magnetic field device 30 can generate a magnetic field in the drawer 20, and the magnetic field can act on the food material in the drawer 20. Therefore, the crystal nucleus growth of the food material is inhibited, the growth rate of the ice crystals is higher than the migration rate of water molecules, and the ice crystals generated by the food material are smaller.

That is, the food material is allowed to be at the same low temperature without generating large ice crystals. And further, the damage to the food cells can be reduced, and the nutrition and the taste of the food are ensured. The storage effect of the food materials is improved.

The magnetic field generating member 31 may be a permanent magnet sheet. Alternatively, the magnetic field means 30 is a separate permanent magnet sheet. Alternatively, the magnetic field means 30 is a separate electrical coil.

Referring to fig. 6 and 7, further, the storage container includes two magnetic field devices 30, and the two magnetic field devices 30 are respectively disposed at opposite inner walls of the outer tub 10. Specifically, two magnetic field devices 30 are provided at the top and bottom of the outer tub 10, respectively. By providing two magnetic field means 30, the magnetic field effect can be enhanced while helping to make the magnetic field more uniform.

It should be noted that the two magnetic field devices 30 may be disposed on the left and right sides of the drawer 20, respectively.

Further, as shown in fig. 7, the storage container includes two magnetic strips 40. Two magnetic guides 40 are respectively located at opposite sides of the drawer 20 retracted at the tub 10. And the magnetic tape 40 is located between the two magnetic field means 30. Both ends of the magnetic conductive tape 40 are connected to the magnetic conductive sheets 32 of the two magnetic field devices 30, respectively.

By providing the magnetic guide strip 40 between the two magnetic field devices 30, an annular magnetic conduction path surrounding the drawer 20 can be formed, improving the uniformity of the magnetic field within the drawer 20. Meanwhile, the release of the magnetic field to the outside can be reduced, and the interference to other parts outside the storage container is reduced.

It should be noted that, when the two magnetic field devices 30 are disposed on the left and right sides of the drawer 20, the two magnetic strips 40 are disposed on the top and bottom sides of the drawer 20, respectively.
