The drawer assembly 100 according to the first aspect of the present invention will be described with reference to fig. 1 to 5, wherein the top, bottom, left, right, front and back directions in the drawings are only for illustrating the relative positions of the structures, and are not intended to limit the present invention, and the drawer assembly 100 and the refrigeration appliance having the same according to the embodiment of the present invention may be disposed in any direction and used.
As shown in fig. 1 to 5, a drawer assembly 100 according to an embodiment of the present invention includes a drawer 10, a vacuum film 30, and a cover plate 20.
Specifically, the drawer 10 defines a receiving cavity 10a having a top opening, the vacuum film 30 is disposed in the receiving cavity 10a and a peripheral edge of the vacuum film 30 is connected to an edge of the top opening, the cover plate 20 is disposed on the top of the drawer 10 to open or close the top opening, and the cover plate 20 is hermetically connected to the peripheral edge of the vacuum film 30 to define a storage space 30a under a condition that the cover plate 20 closes the top opening, wherein the cover plate 20 is provided with a pumping hole 211, and the vacuum film 30 is configured to be shrunk and deformed under a condition that the storage space 30a is pumped through the pumping hole 211.
As shown in fig. 3, a portion of the vacuum film 30 adjacent to the edge is fixed between the cover plate 20 and the drawer 10, the vacuum film 30 divides the receiving chamber 10a into two portions spaced apart from each other, one portion is a storage space 30a defined between the vacuum film 30 and the cover plate 20, the other portion is defined by the vacuum film 30 and an inner wall of the drawer 10, the air suction port 211 is constructed in an openable or closable structure, and when the air suction port 211 is opened, the air suction port 211 communicates the storage space 30a with the outside and sucks air in the storage space 30a to the outside, at this time, the content of air in the storage space 30a is gradually reduced, the oxygen content in the storage space 30a is also gradually reduced, the vacuum film 30 is gradually contracted toward food in the storage space 30a until the storage space 30a reaches a designated vacuum degree, the vacuum film 30 is wrapped on the surface of the food, and at this time, the air suction port 211 is closed, the storage space 30a is formed in a sealed vacuum state.
It should be noted that the vacuum film 30 is configured to prevent both gas and liquid from passing through the vacuum film 30, and the vacuum film 30 may be made of an elastic material or an inelastic material, which is not particularly limited in the present invention.
According to the drawer assembly 100 of the embodiment of the invention, the vacuum film 30 is arranged in the accommodating cavity 10a to define the storage space 30a between the vacuum film 30 and the cover plate 20, the cover plate 20 is provided with the air suction opening 211, and the vacuum film 30 is configured to shrink and deform when the storage space 30a is sucked through the air suction opening 211, so that the drawer assembly 100 has a simpler structure, and the sealing property of the sealed space formed between the vacuum film 30 and the cover plate 20 is better; furthermore, when the storage space 30a is in a vacuum state, the vacuum film 30 is coated on the surface of the food, so that the food is prevented from contacting with the air, the food is prevented from being oxidized, and the food is kept fresh for a long time. Therefore, the drawer assembly 100 according to the embodiment of the invention has the advantages of simple structure, good air tightness, good fresh-keeping effect and the like.
In some embodiments of the present invention, the cover plate 20 is made of a light transmissive material. The transparent material can be understood by those skilled in the art, that is, the user can visually observe the condition in the storage space 30a through the cover plate 20, so that the user can obtain the condition in the storage space 30a in real time during the use process, thereby bringing better use experience to the user.

Specifically, as shown in fig. 3, the initial state means that the vacuum film 30 is disposed closely to the inner surface of the drawer 10 before food is placed into the storage space 30a or the storage space 30a is evacuated, i.e., the capacity of the storage space 30a is substantially equal to the capacity of the receiving cavity 10a regardless of the thickness of the vacuum film 30. Therefore, on one hand, the capacity of the storage space 30a can be maximized, and a user can conveniently store food in the storage space 30 a; on the other hand, after the storage space 30a is evacuated and food is kept fresh, the user opens the cover plate 20 again, and then the vacuum film 30 falls back onto the inner surface of the drawer 10, thereby facilitating the user to take out the food.
In some embodiments of the present invention, as shown in FIGS. 1 and 2, the outer surface of the cover plate 20 has a convex suction nozzle 21, the suction nozzle 21 defining a suction opening 211. Specifically, the air exhaust nozzle 21 is formed by protruding upward the outer surface of the cover plate 20, the air exhaust nozzle 21 is used for being connected with the vacuum pump, the air exhaust port 211 extends along the axial direction of the air exhaust nozzle 21 and penetrates through the cover plate 20 in the thickness direction of the cover plate 20 so as to communicate the accommodating cavity 10a with the vacuum pump, and therefore, the connection of the air exhaust nozzle 21 and the vacuum pump is convenient, and the installation and the disassembly are convenient.
In some embodiments of the present invention, as shown in fig. 1-3, the cover plate 20 is provided with an air return valve 22, and the air return valve 22 is configured to achieve sealing in a closed state and to vent air into the storage space 30a in an open state. That is, the air return valve 22 is configured to be opened or closed, for example, when the storage space 30a is pumped or food is kept fresh, the air return valve 22 is closed, and the storage space 30a is not communicated with the outside; when the food needs to be taken out from the storage space 30a, the air return valve 22 can be opened to communicate the storage space 30a with the outside, at this time, air enters the storage space 30a from the air return valve 22 to restore the normal pressure in the storage space 30a, and the vacuum film 30 is no longer coated on the surface of the food, so that the cover plate 20 is opened and the food is taken out.

Specifically, the sealing member 40 is an elastic member, the sealing member 40 may be installed at the cover plate 20 or at the drawer 10, the sealing member 40 is located between the lower surface of the cover plate 20 and the upper surface of the drawer 10 when the cover plate 20 closes the top opening, and the sealing member 40 is elastically deformed by itself to seal the gap between the cover plate 20 and the drawer 10. Therefore, the air tightness between the accommodating cavity 10a and the outside is better, and the fresh-keeping effect of the food is further improved.
Alternatively, as shown in fig. 2, the sealing member 40 is formed in a ring shape extending along the circumference of the top opening, and the outer edge of the vacuum film 30 is fixed to the drawer 10 by the sealing member 40. Specifically, the outer edge of the vacuum film 30 is fixed between the sealing member 40 and the upper surface of the drawer 10, whereby the sealing member 40 can seal the gap between the vacuum film 30 and the cover plate 20, and the sealing effect of the ring-shaped sealing member 40 is more excellent. Preferably, the sealing member 40 is a rubber ring, and thus, the sealing member 40 is commercially available in material and is manufactured at a low cost.
