The embodiment of the application provides a vacuum preservation device and a refrigerator to solve the problem that inconvenient opening of a containing groove of the vacuum preservation device is inconvenient.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a portion of a box and a vacuum refreshing apparatus of the refrigerator shown in fig. 1. The embodiment of the application provides a vacuum refreshing device 100 which is suitable for a refrigerator. The refrigerator includes a cabinet 200. The cabinet 200 may have one storage compartment 21 or a plurality of storage compartments 21, and the number of storage compartments 21 provided in the cabinet 200 is not limited in the embodiment of the present application. The refrigerator provided in the embodiment of the present application may be provided with one vacuum refreshing apparatus 100 in each storage compartment 21, or may be provided with one or more vacuum refreshing apparatuses 100 in individual storage compartments 21, which is not limited in the embodiment of the present application. Next, the embodiment of the present invention will be explained in detail by taking an example in which the vacuum refreshing apparatus 100 is installed in one of the storage compartments 21 of the box 200.

As shown in fig. 2, a second opening 22 may be provided on a sidewall forming the storage compartment 21 to allow the vacuum refreshing apparatus 100 to be put into or taken out of the storage compartment 21. To facilitate the access of the vacuum refreshing apparatus 100, a first slider 23 is mounted on a sidewall forming the second opening 22, and the first slider 23 is connected to the second slider 24 such that the second slider 24 can slide to be partially outside the storage compartment 21. The vacuum refreshing apparatus 100 may be placed on the second slide 24. The vacuum refreshing apparatus 100 can be easily pushed into the storage compartment 21 or pulled out of the storage compartment 21 by pulling the second slider 24.

Referring to fig. 3 and 4, fig. 3 is a schematic structural view illustrating an opened state of a lid of the vacuum refreshing apparatus shown in fig. 2, and fig. 4 is an exploded view illustrating the lid, a handle, a sealing member and an elastic member of the vacuum refreshing apparatus shown in fig. 2.

As shown in fig. 3 and 4, the vacuum refreshing apparatus 100 may include a case body 11, a box cover 12, and a sealing member 13. Illustratively, the box 11 has a container 111 for storing food such as fruits and vegetables. The cover 12 and the body 11 are rotatably coupled so that the cover 12 can open or close the receiving groove 111 by rotating. The lid 12 is provided with a pressure relief hole 1211, and when the lid 12 closes the receiving groove 111, the pressure relief hole 1211 is communicated with the receiving groove 111, so that the receiving groove 111 can be communicated with the outside. The seal 13 can open or close the pressure relief orifice 1211. Furthermore, after the sealing element 13 seals the pressure relief hole 1211, the air in the accommodating groove 111 may be extracted by the vacuum extractor, so that a low vacuum environment is formed in the accommodating groove 111, for example, 20% of the air in the accommodating groove 111 is extracted by the vacuum extractor, so that a low vacuum environment of 0.8 atm is formed in the accommodating groove 111, and according to the storage requirements of different foods, 15% or 25% of the air in the accommodating groove 111 may also be extracted, which is not limited in the embodiment of the present invention. Alternatively, after the sealing element 13 opens the accommodating cavity 111, air outside the accommodating cavity 111 may enter the accommodating cavity 111 through the pressure relief hole 1211, so that air pressure inside and outside the accommodating cavity 111 is balanced, and after the air pressure inside and outside the accommodating cavity 111 is balanced, the lid 12 may be opened to store fruits and vegetables and other food into the accommodating cavity 111.

It can be understood that, in the technical solution before the improvement, the box body 11 and the box cover 12 are further provided with locking devices, and after the box cover 12 closes the containing groove 111, the locking devices can lock the box cover 12 and the box body 11, so as to prevent the box cover 12 and the box body 11 from being accidentally opened. Accordingly, when the user opens the box cover 12 to take out the food such as fruits and vegetables in the container 111, the process is as follows: first, the sealing member 13 is opened to balance the air pressure inside and outside the accommodating groove 111; then, the locking device is opened, so that the box body 11 and the box cover 12 are unlocked; finally, the lid 12 is rotated to open the container 111 so as to take out the food such as fruits and vegetables in the container 111. It follows that the mutual independence of the locking means and the sealing member 13 results in a cumbersome procedure for the user to take the food in the receiving slot 111.

As shown in fig. 4, in the embodiment of the present application, the handle 14 is used to replace the locking device in the prior art. The handle 14 is rotatably mounted on the cap 12, and the handle 14 is also connected to the sealing member 13. In one aspect, the handle 14 can be rotated in a first direction to lock the handle 14 to the case 11 and to close the pressure relief opening 1211 with the seal 13. On the other hand, the handle 14 can be rotated in the second direction to unlock the handle 14 and the case 11 and bring the sealing member 13 to open the pressure relief hole 1211. Therefore, the vacuum refreshing device 100 provided by the embodiment of the application can complete the pressure relief operation of the accommodating groove 111 and the unlocking operation of the box body 11 and the handle 14 simultaneously by rotating the handle 14, so that the vacuum refreshing device 100 provided by the embodiment of the application has the advantage of being more convenient and faster to use.

In this embodiment of the application, the first direction may be a clockwise direction, and the second direction may be a counterclockwise direction, or the first direction may be a counterclockwise direction, and the second direction may be a clockwise direction, which is not limited in this embodiment of the application.

Referring to fig. 5, fig. 5 is an assembly view of the handle, the sealing member and the elastic member of the vacuum refreshing apparatus shown in fig. 2. The handle 14 may include a shaft 141, a barb 142, a seal securing block 143, and a grip plate 144.

As shown in fig. 5, the shaft body 141 may be entirely cylindrical or partially cylindrical, and the cylindrical portion of the shaft body 141 may be rotatably connected to the case cover 12. Of course, the embodiment of the present invention is not limited to a specific shape of the shaft body 141, for example, the shaft body 141 may also be polygonal prism-shaped, and after a shaft sleeve is sleeved on the polygonal prism-shaped shaft body 141, the shaft sleeve is rotatably connected to the box body 200.

As shown in fig. 5, one end of the sealing element fixing block 143 is fixedly connected to the shaft body 141, and further, when the shaft body 141 rotates, the sealing element 13 is driven to rotate around the axis of the shaft body 141. The other end of the sealing element fixing block 143 is fixedly connected to the sealing element 13, and the sealing element 13 can rotate around the axis of the shaft body 141 along with the sealing element fixing block 143. During the rotation of the sealing member fixing block 143 in the first direction, the sealing member 13 may rotate to be attached to the cap 12, so that the sealing member 13 completely closes the pressure relief hole 1211 formed in the cap 12. During the rotation of the sealing member fixing block 143 in the second direction, the sealing member 13 may be rotated to be separated from the cap 12, so that the sealing member 13 opens the pressure relief hole 1211 provided on the cap 12.

As shown in fig. 5, the barb 142 is disposed opposite to the seal fixing block 143 on both sides of the shaft body 141 in the radial direction. In the embodiment of the present application, after the vacuum refreshing apparatus 100 is placed in the storage compartment 21, the shaft body 141 is located above the receiving groove 111, and the barbs 142 are disposed on the left and right sides of the shaft body 141 opposite to the sealing member 13. At this time, one end of the barb 142 is connected to the shaft body 141. The end of the barb 142 away from the shaft body 141 bends downward, and the end away from the shaft body 141 to the rear is also provided with a clamping part 1421 facing away from the side wall of the sealing element fixing block 143. Correspondingly, the side wall of the box body 11 close to the handle 14 is provided with an extending portion 112, and the extending portion 112 is located outside the accommodating groove 111. The extending portion 112 is provided with a locking hole 113 penetrating vertically.

Referring to fig. 6-8, fig. 6 is a top view of the vacuum refreshing apparatus shown in fig. 2, fig. 7 is a cross-sectional view of the vacuum refreshing apparatus shown in fig. 6 taken along a direction P-P, and fig. 8 is a partial enlarged view of a cross-sectional view of the vacuum refreshing apparatus shown in fig. 7 taken along the direction P-P at a position X.

As shown in fig. 8, when the barbs 142 follow the shaft body 141 to rotate around the axial line of the first shaft body 141 to a locked state during the rotation of the shaft body 141 in the first direction, the barbs 142 can also follow the rotation of the box cover 12 synchronously. At this time, the catching portions 1421 of the barbs 142 interfere with the extension portions 112, so that the barbs 142 cannot pass through the locking holes 113. Further, when the box cover 12 is in a state of closing the receiving groove 111, the upper surface of the clamping portion 1421 abuts against the lower surface of the extending portion 112, so as to limit the shaft body 141 to drive the barb 142 to rotate along the first direction, so that the handle 14 and the box body 11 are locked. Meanwhile, the sealing member 13 presses against the cap 12 and closes the pressure relief hole 1211 formed in the cap 12.

It can be understood that when the handle 14 is locked with the box body 11 and the sealing member 13 seals the pressure relief hole 1211, the containing groove 111 is completely sealed, and at this time, a part of air in the containing groove 111 is pumped away by the vacuum pumping device, so that a low vacuum environment is formed in the containing groove 111. Because the air pressure in the accommodating groove 111 is smaller than the air pressure outside the accommodating groove 111, the box cover 12 can be pressed on the box body 11 and the sealing element 13 can be pressed on the box cover 12 by the air pressure difference between the inside and the outside of the accommodating groove 111. On the other hand, since the sealing member 13 is connected to the sealing member fixing block 143 of the handle 14, the air pressure difference between the inside and the outside of the accommodating groove 111 also drives the handle 14 to be kept in the locked state, and the handle 14 can be rotated only by applying a larger external force to the handle 14 to overcome the air pressure difference between the inside and the outside of the accommodating groove 111, so that the handle 14 is unlocked from the case 11.

When the barbs 142 follow the shaft body 141 to rotate around the axial lead of the first shaft body 141 to the unlocked state in the process of rotating the shaft body 141 in the second direction, the barbs 142 can also synchronously rotate along with the box body 11. At this time, the catching portions 1421 of the barbs 142 may pass through the locking holes 113 directly without interfering with the extending portions 112 in the process of rotating following the cartridge body 11. On the other hand, the shaft body 141 rotates the barb 142 to the unlocking state, and simultaneously, the sealing element 13 is separated from the box cover 12, namely, the sealing element 13 completely opens the pressure relief hole 1211. At this time, the external air may flow into the receiving groove 111 through the pressure relief hole 1211 quickly, so that the air pressures inside and outside the receiving groove 111 are equal. When the air pressure inside and outside the containing groove 111 is equal, the handle 14 can be pulled to drive the handle 14 and the box cover 12 to rotate synchronously, so that the containing groove 111 is opened, and finally, the user can store and take food in and out of the containing groove 111.

As can be seen from the above state change of the handle 14 during the rotation of the shaft body 141, the vacuum refreshing apparatus 100 according to the embodiment of the present application may lock the handle 14 with the box body 200 and close the pressure relief hole 1211 by the sealing member 13 by rotating the handle 14 in the first direction, unlock the handle 14 with the box body 200 and open the pressure relief hole 1211 by the sealing member 13 by rotating the handle 14 in the second direction. Therefore, the vacuum refreshing device 100 provided by the embodiment of the present application has the advantages of being simple in operation and convenient for quickly opening the accommodating groove 111.

As shown in fig. 5, the grip plate 144 may include a grip plate body and two connecting arms. Two opposite ends of the holding plate main body are respectively provided with a connecting arm. Both connecting arms are connected to the shaft 141, so that the shaft 141 can be driven to rotate when the user pulls the holding plate 144.

It is understood that the handle 14 may be regarded as a lever as a whole, a fulcrum of the lever is located on an axial line of the shaft body 141, a power arm of the lever is a distance from the main body of the grip plate to the axial line of the shaft body 141, a resistance arm of the lever is a distance from the snap-in portion 1421 to the axial line of the shaft body 141, and another resistance arm of the lever is a distance from the fixing block 143 to the axial line of the shaft body 141. Under the unchangeable condition of two resistance arms of this lever, the board main part of gripping passes through the linking arm and is connected with axis body 141 for the power arm of this lever lengthens, and then makes the user can rotate handle 14 more laborsavingly.

In the embodiment of the present application, the box cover 12 may include a cover body and a decoration cover.

As shown in fig. 4, the cap body includes a first cover plate 121 and a second cover plate 122. The end of the second cover plate 122 away from the handle 14 is rotatably connected to the case 200 via a damping shaft. The first cover plate 121 may be fixed on a side of the second cover plate 122 facing the receiving groove 111 by glass cement or the like. Furthermore, the first cover plate 121 can be driven to rotate by the second cover plate 122, and the first cover plate 121 can close or open the accommodating groove 111 in the rotating process.

In the embodiment of the present application, the first cover plate 121 may be a cover plate made of transparent materials such as glass and acrylic, and the second cover plate 122 may be made of opaque plastics such as ABS (terpolymer of three monomers of acrylonitrile (a), butadiene (B), and styrene (S)) or HIPS (high impact polystyrene). The middle portion of the second cover plate 122 is provided with a notch facing the inside of the receiving groove 111. At this time, since the second cover plate 122 is opaque and the first cover plate 121 is transparent, the gap can form a viewing window 1221 for a user to view fruits and vegetables in the accommodating groove 111.

As shown in fig. 4, the decoration cover is disposed on a side of the cover plate body facing away from the receiving groove 111. The deco cover has a mounting space 125, the mounting space 125 communicates with the pressure relief hole 1211, and the mounting space 125 also communicates with the locking hole 113. Further, the external air may pass through the locking hole 113 and the installation space 125, and the air introduced into the installation space 125 may further enter the receiving groove 111 through the pressure relief hole 1211. At this time, a portion of the barb 142, a portion of the shaft body 141, the packing fixing block 143, and the packing 13 are disposed in the installation space 125, so that the trim cover can cover a portion of the handle 14 and the packing 13. When a part of the handle 14 and the sealing member 13 are hidden in the trim cover, on one hand, the handle 14 is more beautiful as a whole, and on the other hand, the sealing member 13 and other parts hidden in the trim cover can be prevented from being damaged.

In the present embodiment, the decorative cover may include a first cover body 123 and a second cover body 124.

As shown in fig. 4, the first cover 123 is connected to the second cover plate 122 and is located on a side of the second cover plate 122 opposite to the first cover plate 121, so that the first cover 123 is located outside the accommodating groove 111. The first cover 123 and the second cover 122 may be assembled together after being molded separately, or the first cover 123 and the second cover 122 may be integrally molded, which is not limited in this embodiment of the application.

As shown in fig. 4, the first cover 123 has a first opening 1231 away from the extension 112. In the embodiment of the present application, the first opening 1231 may be a side facing the box cover 12 rotatably connected to the box body 200. The sidewall forming the first opening 1231 includes a first sidewall 1232 and a second sidewall 1233 disposed opposite to each other. The first side wall 1232 and the second side wall 1233 are oppositely provided with a sliding groove 1234, the sliding groove 1234 is communicated with the first opening 1231, so that the shaft body 141 can be pushed into the sliding groove 1234 through the first opening 1231, and can rotate and slide in the sliding groove 1234, and the corresponding shaft body 141 in the sliding groove 1234 can also slide in the sliding groove 1234 to the first opening 1231 and separate from the first cover 123. For example, the outer diameter of the shaft body 141 is equal to the groove width of the sliding groove 1234. On the other hand, the barb 142, the seal fixing block 143, and the seal 13 can all pass through the first opening 1231.

As shown in fig. 4, the second cover 124 is detachably connected to the first cover 123 to close the first opening 1231. For example, the second cover 124 and the first cover 123 may be connected by a snap connection, a magnetic connection, or the like, which is easy to detach and install. The second cover 124 has two protrusions 1241, and the two protrusions 1241 are respectively disposed in one sliding groove 1234. Further, the protrusion 1241 and the sidewall forming the corresponding sliding groove 1234 form a shaft hole for the shaft body 141 to rotate, so that the shaft body 141 slides in the sliding groove 1234 after being mounted. On the other hand, during the rotation of the handle 14, the first cover 123 and/or the second cover 124 are at least partially sandwiched between the two connecting arms of the holding plate 144 of the handle 14, so as to limit the degree of freedom of the shaft body 141 from the sliding groove 1234 along the radial direction of the shaft body 141. Therefore, when the first cover 123 and the second cover 124 are coupled, the handle 14 can be rotated only in the slide groove 1234.

As shown in fig. 5 and 8, in the embodiment of the present application, the vacuum refreshing apparatus 100 further includes an elastic member 15. The side wall forming the installation space 125 includes a first top wall 1235 away from the first cover plate 121, and an elastic member 15 is disposed in the installation space 125, and the elastic member 15 is pre-pressed between the first top wall 1235 and the sealing member fixing block 143 to drive the handle 14 to rotate in the first direction.

On one hand, when the handle 14 is free from external force, the elastic member 15 can drive the handle 14 to rotate, so that the sealing member 13 seals the pressure relief hole 1211, and further before the accommodating groove 111 is vacuumized, a user does not need to manually rotate the handle 14 so that the sealing member 13 seals the pressure relief hole 1211, so that the vacuum refreshing device 100 provided by the embodiment of the application has the advantage of convenience and convenience in use. On the other hand, after a low vacuum environment is formed in the receiving groove 111, if the handle 14 needs to be rotated to complete the pressure relief operation of the sealing member 13, the external force of the handle 14 needs to overcome the pressure difference between the inside and the outside of the receiving groove 111, and the elastic restoring force of the elastic member 15. Therefore, the vacuum refreshing device 100 provided by the embodiment of the present application can prevent the handle 14 from being rotated due to the external object accidentally pressing on the handle 14, and the sealing member 13 accidentally opens the pressure relief hole 1211, so that the vacuum refreshing device 100 has the advantages of stable and reliable structure.

As shown in fig. 5 and 8, the elastic member 15 includes a torsion spring. The shaft body 141 is provided with a mounting notch 1411 at an axially middle portion. The torsion spring has a spiral portion 151, the spiral portion 151 is disposed on the shaft body 141, and a width of the spiral portion 151 along the axial direction of the shaft body 141 is greater than a width of the mounting notch 1411 along the axial direction of the shaft body 141. Furthermore, when the screw 151 slides to the mounting notch 1411 along the axial direction of the shaft 141, the screw 151 can be removed from the shaft 141, or vice versa, the screw 151 can be sleeved on the shaft 141. One end of the spiral part 151 is provided with a first torsion arm 152, and the first torsion arm 152 presses against the first top wall 1235. The other end of the spiral portion 151 is provided with a second torsion arm 153, and the second torsion arm 153 presses against the side wall of the sealing element fixing block 143 facing the first top wall 1235.

Of course, the specific structure of the elastic member 15 is not limited in the embodiments of the present application, for example, the elastic member 15 may also be a compression spring or a spring.

The working principle of the embodiment of the present application is further explained below in connection with the installation process of the handle 14, as shown in fig. 4:
