Referring to fig. 1 to 5, the present invention provides a storage device 10, which can be used as a refrigerator, and generally includes a refrigeration system, where the refrigeration system may include a compressor, an evaporator, and other components to provide suitable refrigeration capacity for the storage device 10, so as to perform refrigeration or freezing on food stored in the storage device 10.

In some embodiments of the present invention, the storage device 10 may further include a box 100, a door 200, a pivot 300, and a push member 400.

The storage space 110 is defined in the box body 100, so that a user can store food and other articles in the storage space 110 for refrigeration or freezing, and the storage space 110 has certain heat preservation performance, and can prevent the heat exchange between the air inside the storage space and the outside air, so as to ensure the refrigeration or freezing effect.

The door 200 is used for opening and closing the storage space 110, a sealing strip 210 is disposed on a region of the door 200 contacting the cabinet 100, and an accommodating space 120 is opened on a region of the front surface of the cabinet 100 opposite to the sealing strip 210.

The pivoting member 300 is pivotally connected to the door body 200, and the first end 302 of the pivoting member 300 protrudes from one side of the door body 200 facing the accommodating space 120 through rotation.

The pushing member 400 is disposed in the accommodating space 120, and is configured to be driven by the first end 302 of the pivoting member 300 to extend from the accommodating space 120 and press the sealing strip 210, so that a gap is formed between the door 200 and the cabinet 100 to allow external air to enter the storage space 110 through the gap, and further balance the pressure between the storage space 110 and the outside.

Since the temperature in the storage space 110 is generally lower than the outside temperature, the door 200 is provided with a sealing strip 210 to prevent the air in the storage space 110 from leaking. The sealing strip 210 may extend along a contact area between the door 200 and the cabinet 100, and when the door 200 is closed, the sealing strip 210 may seal a gap between the door 200 and the cabinet 100. However, after the door 200 is closed, since the temperature in the storage space 110 is generally lower than the outside temperature, the pressure in the storage space 110 is lower than the atmospheric pressure outside, and a user needs to apply a large force to open the storage space when the user needs to take and place food by the door 200.

In order to overcome the above defects, the storage device 10 of the embodiment adopts the lever principle to realize that a gap is formed between the door body 200 and the box body 100 when a user opens the door, so that the internal and external pressure difference is balanced, the strength is saved, and the front surface of the box body cannot be damaged.

Specifically, the pivoting member 300 may be pivotally connected to the door body 200 through a pivoting shaft 330, and the pushing member 400 is disposed in the accommodating space 120 on the box body 100, where the accommodating space 120 has an opening facing the sealing strip 210 on the door body 200. When the pivoting member 300 is driven by a driving force, the first end 302 of the pivoting member 300 can rotate towards the pushing member 400, and the pushing member 400 is driven to extend towards the sealing strip 210, so as to press the sealing strip 210 and balance the internal pressure and the external pressure of the storage space 110.

In some specific embodiments, the pushing member 400 may be rotatably disposed in the accommodating space 120 through a rotating shaft 410, a first end 402 of the pushing member 400 is opposite to the first end 302 of the pivoting member 300, a second end 404 of the pushing member 400 is opposite to the sealing strip 210, and the pushing member 400 is configured to abut against the first end 402 of the pushing member 400 after the first end 302 of the pivoting member 300 protrudes from the door body 200, and the second end 404 of the pushing member 400 rotates out of the accommodating space 120 and presses the sealing strip 210, so that a gap is formed between the door body 200 and the box body 100, so as to allow external air to enter the storage space 110 through the gap, and further balance the pressure of the storage space 110 and the outside.

After the first end 302 of the pivoting member 300 protrudes from the sidewall of the door 200 by rotating, the first end 302 abuts against the first end 402 of the pushing member 400, the pushing member 400 receives a driving force of the rotation, so that the second end 404 of the pushing member 400 is rotated out of the accommodating space 120, and the second end 404 of the pushing member 400 can press the sealing strip 210, so that a gap is formed between the door 200 and the box 100, and the external air enters the storage space 110 through the gap, so that the storage space 110 is rapidly balanced with the external air pressure, and the door 200 can be smoothly opened.

In this embodiment, since the second end 404 of the pushing member 400 reversely presses the sealing tape 210, instead of directly acting on the surface of the box 100 by using the principle of lever, this not only reduces the force required to lean against the door, but also reduces the damage to the box 100 caused by the door opening action.

Referring to fig. 5, in particular, in the present embodiment, the pivot shaft 330 of the pivot member 300 can be disposed near the first end 302 thereof. Because in the process of opening the door, only need with sealing strip 210 extrusion department gap can, consequently set up the pivot axis 330 of pivot piece 300 and be close to its first end 302 not only can control the gap size, avoid causing the damage to sealing strip 210, and the pivot axis 330 sets up and is close to its first end 302, keeps away from second end 304 promptly, because second end 304 is the application of force end, keeps away from its second end 304 and can increase the arm of force length of lever for the user is more laborsaving when the second end 304 application of force of pivot piece 300.

Alternatively, the door 200 may be a casing of a drawer, that is, the storage device 10 in this embodiment is a drawer-type refrigerator, and the storage space 110 is opened and closed by drawing the drawer. Wherein the sealing strip 210 is disposed on the outer shell of the drawer in the area contacting the box 100, and the pivot 300 is rotatably disposed on the inner wall of the outer shell of the drawer to drive the first end 402 of the pushing member 400, which also achieves the technical effects of the above-mentioned embodiments.

Referring to fig. 1, 4 and 5, in some embodiments, the storage device 10 may further include a handle 500, the handle 500 is disposed at an outer side of the door body 200, an upper section 502 and a lower section 504 of the handle 500 are respectively and correspondingly disposed with one of the pivoting members 300 and respectively connected to the second ends 304 of the pivoting members 300, and the handle 500 is configured to drive the two pivoting members 300 to rotate simultaneously, so that the first ends 302 of the two pivoting members 300 protrude out of the door body 200 at the same time.

In this embodiment, the handle 500 may be disposed along the height direction of the door body 200, and the upper section 502 and the lower section 504 thereof are respectively connected to the second end 304 of the pivoting member 300. When a user needs to open the door, the handle 500 may move up and down in the height direction of the door body 200 to provide a rotational driving force to the pivoting member 300.

In addition, the upper section 502 and the lower section 504 of the handle 500 in this embodiment are respectively connected to a pivoting member 300, and correspondingly, two accommodating spaces 120 are disposed on the surface of the box 100, and a pushing member 400 is pivotally disposed inside each accommodating space 120. When the door is opened, the first ends 302 of the two pivoting members 300 can respectively provide the two pushing members 400 with rotational driving force, so that the second ends 404 of the two pushing members 400 simultaneously press the sealing strip 210 to accelerate the speed of pressure balancing. Compared with single-side extrusion, the storage device 10 of the present embodiment avoids excessive deformation of the sealing strip 210 as much as possible under the same pressure balancing speed.

In some embodiments, the door 200 is pivotally connected to one side of the cabinet 100 to open and close the storage space 110; and the two pivoting members 300 are both disposed on the side wall of the door body 200 away from the pivoting shaft (not shown in the figure) thereof, so that the two pivoting members 300 rotate in a plane parallel to the side wall of the door body 200.

Referring to fig. 2 to 4, in the present embodiment, the door 200 may be pivotally connected to the right side of the cabinet 100, the two pivoting members 300 may be parallel to the side wall of the door 200 away from the pivoting axis thereof, and may be disposed up and down, the handle 500 is also disposed on a side away from the pivoting axis of the door 200, and the upper section 502 and the lower section 504 of the handle 500 may extend perpendicular to the surface of the door 200 and are connected to the two pivoting members 300. When a user needs to open the door, on one hand, the user can apply a forward driving force along the door body 200 to the handle 500, and the handle 500 is far away from the pivoting shaft of the door body 200, so that the moment required by normal door opening can be provided; on the other hand, the user can apply a downward or upward driving force to the handle 500 to rotate the pivoting member 300 to squeeze the sealing tape 210. When the door is opened, although the force applied to the handle by the user is applied in two directions, since the two forces are applied to the handle 500 together, it can be simultaneously performed without any other operation.

In some embodiments, a limit guide structure is provided between the pivoting member 300 and the door body 200 to limit the rotation angle of the pivoting member 300, that is, to limit the distance that the first end 302 of the pivoting member 300 protrudes from the door body 200.

Referring to fig. 5, specifically, the limiting guide structure includes a limiting groove 320 disposed on the pivoting member 300 and a limiting post 220 formed on the door body 200, the limiting groove 320 extends in an arc shape with the pivoting shaft 330 of the pivoting member 300 as a center, and the limiting post 220 is slidably disposed in the limiting groove 320.

In the embodiment, the limiting groove 320 extends in an arc shape around the pivot shaft 330 of the pivot member 300, and when the pivot member 300 rotates around the pivot shaft 330, the limiting post 220 can rotate along the limiting groove 320. Because the arc length of the limiting groove 320 is limited, when the limiting post 220 abuts against two extreme positions of the limiting groove 320, the integral rotation angle of the pivoting member 300 is limited, the distance that the first end 302 of the pivoting member 300 protrudes out of the door body 200 is indirectly limited, and the depth that the second end 404 of the pushing member 400 extrudes the sealing strip 210 is further limited, so that the extrusion depth is in a controllable range, and the sealing strip 210 is protected.

Referring to fig. 1, 4 and 5, in some embodiments, the storage device 10 may further include a first return spring 310, wherein two ends of the first return spring 310 are respectively connected to the door body 200 and the pivoting member 300, and are configured to generate an elastic restoring force in a process that the pivoting member 300 rotates towards the accommodating space 120, and the pivoting member 300 is urged to rotate away from the accommodating space 120 by the elastic restoring force.

The first return spring 310 in this embodiment deforms when the first end 302 of the pivoting member 300 protrudes out of the door body 200, so as to generate an elastic restoring force. When the stress on the pivoting member 300 disappears or the stress on the pivoting member 300 is smaller than the elastic restoring force, the pivoting member 300 is driven to rotate reversely, so that the pivoting member 300 is hidden at the side of the door body 200 to prepare for the next rotation of the pivoting member 300.

Optionally, the first return spring 310 in this embodiment may also be configured to not deform when the position-limiting post 220 abuts against one of the extreme positions of the position-limiting groove 320, and the first return spring 310 deforms gradually when the position-limiting post 220 moves to the other extreme position.

Alternatively, the first return spring 310 in this embodiment may be configured as a compression spring, an extension spring, or the like, and one skilled in the art may select the installation position according to the technical solution of the present invention, so that the pivoting member 300 is extended or compressed when rotated to generate the elastic restoring force.

Referring to fig. 1 to 3, in some embodiments, the storage device 10 may further include a second return spring 420, wherein the second return spring 420 is sleeved on the rotating shaft 410 of the pushing member 400, and is configured to deform during the process of rotating the pushing member 400 out of the accommodating space 120, and to utilize the elastic restoring force of the second return spring 420 to restore the pushing member 400 after the first end 402 of the pushing member 400 is released by the urging force of the pivoting member 300.

Specifically, the second return spring 420 of the present embodiment may be configured as a torsion spring sleeved on the rotating shaft 410 of the pushing member 400. In the rotation process of the pushing member 400, the torsion spring is pressed to deform, and further generates an elastic restoring force, when the pushing member 400 is forced to disappear by the pivot member 300 or the forcing force is smaller than the elastic restoring force, the pushing member 400 rotates reversely, so that the second end 404 is no longer in a state of pressing the sealing strip 210, and preparation is made for the next rotation.

In some embodiments, the first end of the pivot 300 is arc-shaped, that is, the first end of the pivot 300 facing the pushing member 400 is arc-shaped, so that when the first end of the pivot 300 abuts against the first end of the pushing member 400, the first end surface of the pushing member 400 is protected, and the rotation precision and the service life of the pushing member 400 are improved.

In some embodiments, the distance between the pivoting shafts 330 of the two pivoting members 300 is 10-30 cm, for example, 10cm, 20cm, or 30cm, so as to achieve the effect of opening the door with assistance while appropriately reducing the length of the handle 500, thereby reducing the occupied space of the handle 500.

Referring to fig. 1 and 3, in some embodiments, the storage device 10 may further include a cover 230 disposed on a sidewall of the door body 200 to protect the pivot member 300, and a connection hole (not shown) is further formed at a connection position of the cover 230 and the sidewall of the door body 200, so that the second end 304 of the pivot member 300 passes through the cover 230 and is connected to the handle 500.
