TECHNICAL FIELD
[0001] The utility model belongs to the technical field of frozen fresh-keeping, and particularly relates to a frozen fresh-keeping box and a refrigerator. BACKGROUND
[0002] How to better freeze and store food is a problem that developers have been researching and a problem that users are more concerned about. On a conventional refrigerator, a freezing chamber works by a compressor to refrigerate, an air duct blows cold air into the freezing chamber, and the overall temperature of the freezing chamber is reduced to freeze food. This preservation method is not very friendly to some food that needs to be frozen for a long time, and a long freezing time can affect the meat texture of food. This is because, during conventional freezing, water forms ice crystals, and larger ice crystals can pierce the cell walls of food, resulting in the loss of nutrient liquid and affecting the meat texture of food. Therefore, fast freezing technology is developed, which can make the size of water when it forms ice crystals smaller, so that the ice crystals cannot pierce the cell walls, and the cell liquid will not flow out, thereby ensuring the freshness of the meat texture of food.
[0003] Currently, there are mainly two kinds of fast freezing technologies applied on refrigerators: one is to use a compressor with better performance and higher cost, which can provide better refrigeration capacity to make the temperature of the freezing chamber reach-30 DEG C or even-40 DEG C; the other is to use some tools to accelerate freezing, such as a metal freezing plate, to increase the contact area (heat transfer efficiency) between food and cold air to accelerate the freezing efficiency by about 1 / 2-1 times. Although the above two methods can accelerate freezing, their disadvantages are also obvious. Using a compressor with better performance can make the minimum temperature of the freezing chamber lower, but the freezing chamber uses air as a medium for heat transfer, and the freezing temperature of the refrigerator cannot meet the fast cooling temperature of food; and using a compressor with better performance will increase energy consumption and cause unnecessary waste. The essence of the freezing metal plate to accelerate the freezing rate is still heat transfer, and the ability to improve the freezing effect is limited, and the actual effect of improving food preservation is not obvious. SUMMARY
[0004] Therefore, it is necessary to provide a frozen fresh-keeping box and a refrigerator for solving the above technical problems.
[0005] A frozen fresh-keeping box, the frozen fresh-keeping box comprising:
[0006] a lower cover for containing food;

[0019] In one of the embodiments, one of the lower cover and the upper cover is provided with a groove, and the other is provided with a rotating clamping strip which can rotate a preset angle after being inserted into the groove, and the rotating clamping strip after rotating the preset angle can be limited by the groove wall to limit the upper cover on the lower cover and make the upper cover and the lower cover abut and seal.
[0020] It can be understood that, through the above structure, the upper cover can be conveniently disassembled and assembled on the lower cover, and the sealing of the upper cover and the lower cover can be ensured when the upper cover is connected to the lower cover.

[0025] When the upper cover is connected to the lower cover, the lower cover inner circumferential wall and the upper cover inner circumferential wall surround to form the sealed cavity.
[0026] It can be understood that, through the above structure, the refrigeration and preservation box can effectively disperse the heavy pressure of water in the sealed cavity in the form of a curved surface, and the pressure is uniform, so that the strength of the refrigeration and preservation box can be ensured.
[0027] In one of the embodiments, from the direction of the lower cover to the upper cover, the cavity diameter of the sealed cavity at the position of the lower cover inner circumferential wall gradually increases, and the cavity diameter of the sealed cavity at the position of the upper cover inner circumferential wall gradually decreases.
[0028] In one of the embodiments, the lower cover and the upper cover are arranged symmetrically.

DETAILED DESCRIPTION
[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or may have an intervening component.
[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0043] like Figures 1 to 5 As shown, a freezer container 100 provided in one embodiment of this application includes a lower cover 10, an upper cover 20, and a lid 30. The lower cover 10 is used to hold food (not shown). The upper cover 20 is detachably connected to the lower cover 10, and the upper cover 20 and the lower cover 10 can be closed to form a sealed chamber 101. The upper cover 20 has a water inlet 21, which communicates with the sealed chamber 101, and external water can be added into the sealed chamber 101 through the water inlet 21. The lid 30 is disposed at the location of the water inlet 21 and is detachably connected to the upper cover 20 to seal the water inlet 21. Here, the food is wrapped in a freezer bag, and the freezer bag is used to isolate the food from the water in the sealed chamber 101.
[0044] As can be seen from the above, when using the freezer container 100 of this application, water is added to the sealed chamber 101. The increased volume of the water after freezing in the sealed chamber 101 compresses the food, reducing the pressure of the food environment and lowering the freezing point of the water on the food. This shortens the time it takes for the water on the food to pass through the maximum ice crystal zone, resulting in smaller ice crystals. This is beneficial for preserving the nutrients of the food and has a rapid cooling effect. Furthermore, the freezer container 100 is designed for use with a standalone refrigerator, so its application does not increase the cost of the refrigerator.
[0045] It should be noted that, in use, the water added to the closed cavity 101 through the water inlet 21 needs to fill the closed cavity 101; in addition, the upper cover 20 and the lower cover 10 of the frozen fresh-keeping box 100 have sufficient structural strength, so that the upper cover 20 and the lower cover 10 can withstand the force acting on the upper cover 20 and the lower cover 10 after the water in the closed cavity 101 freezes, so as to further reduce the pressure of the environment where the food is located, thereby maximizing the nutrient preservation effect of the frozen fresh-keeping box 100 when the food is frozen.
[0046] As shown in Figure 1 , Figure 4 , one of the lower cover 10 and the upper cover 20 is provided with a groove 11, and the other is provided with a rotating clamping strip 22. The rotating clamping strip 22 can rotate by a predetermined angle after being inserted into the groove 11, and the rotating clamping strip 22 after rotating by a predetermined angle can abut against the groove wall (not shown in the figure) of the groove 11 for limiting, so as to limit the upper cover 20 on the lower cover 10 and make the upper cover 20 and the lower cover 10 abut and seal. That is, when the upper cover 20 needs to be assembled on the lower cover 10, the rotating clamping strip 22 can be aligned with the groove 11 and inserted first, and then the upper cover 20 is driven to rotate relative to the lower cover 10 to realize the locking between the upper cover 20 and the lower cover 10. This can facilitate the disassembly and assembly of the upper cover 20 on the lower cover 10 and ensure the sealing of the upper cover 20 and the lower cover 10 when they are connected. Here, the rotating clamping strip 22 is L-shaped and is specifically provided on the upper cover 20, and the groove 11 is provided on the lower cover 10. It can be understood that in other embodiments, the rotating clamping strip can also be provided on the lower cover 10, and the groove 11 can be provided on the upper cover 20, or the upper cover 20 and the lower cover 10 can be connected in a threaded manner, which will not be described here.
[0047] As shown in Figure 1 , Figure 4 , the groove 11 and the rotating clamping strip 22 are correspondingly provided; wherein the number of the groove 11 is configured to be multiple, and the multiple grooves 11 are arranged along the circumferential direction of the frozen fresh-keeping box 100, so that the upper cover 20 and the lower cover 10 have multiple connection parts when they are connected, which can improve the stability of the connection between the upper cover 20 and the lower cover 10. Here, the number of the groove 11 is configured to be two, and the two grooves 11 are symmetrically arranged relative to the center line of the frozen fresh-keeping box 100. It can be understood that the number of the groove 11 is not limited to two as shown in the figure, and for those skilled in the art, the number of the groove 11 can also be three, four or even more, which will not be described here.
[0048] As shown in Figure 1 , Figure 4 , Figure 5As shown, the lower cover 10 has a curved lower cover inner circumferential wall 12, and the upper cover 20 has a curved upper cover inner circumferential wall 23; when the upper cover 20 is connected to the lower cover 10, the lower cover inner circumferential wall 12 and the upper cover inner circumferential wall 23 are enclosed to form a closed cavity 101. That is, the cavity wall of the closed cavity 101 of the freezing and fresh-keeping box 100 for containing water is curved, and the curved structure can effectively disperse the heavy pressure of the water in the closed cavity 101 and make the pressure uniform, thereby ensuring the strength of the freezing and fresh-keeping box 100.
[0049] As shown in Figure 4 , Figure 5 , from the lower cover 10 to the upper cover 20, the cavity diameter of the closed cavity 101 at the position of the lower cover inner circumferential wall 12 gradually increases, and the cavity diameter of the closed cavity 101 at the position of the upper cover inner circumferential wall 23 gradually decreases. That is, the closed cavity 101 is disc-shaped. Here, the lower cover 10 and the upper cover 20 are symmetrically arranged.
[0050] As shown in Figure 6 , the cover 30 includes a plurality of hooks 31, and the plurality of hooks 31 are arranged at intervals along the circumferential direction of the cover 30; and the plurality of hooks 31 can pass through the water inlet 21 and abut against the upper cover inner circumferential wall 23 of the upper cover 20 to limit the cover 30 from being separated from the upper cover 20. That is, the cover 30 is connected to the upper cover 20 in a buckling manner, which facilitates the disassembly and assembly of the cover 30 on the upper cover 20. Here, the number of hooks 31 is four, and the hooks 31 can be integrally injection molded with the cover 30 made of plastic material. It can be understood that in other embodiments, the number of hooks 31 on the cover 30 can also be two, three, five, or even more.
[0051] As shown in Figure 6 , the upper cover 20 is formed with a stepped surface 24, and the stepped surface 24 is arranged at the peripheral position of the water inlet 21; correspondingly, the cover 30 is formed with a stepped matching surface 32, and the stepped matching surface 32 can abut against the stepped surface 24 to limit the position. That is, when the hooks 31 on the cover 30 are inserted along the water inlet 21 of the upper cover 20, the abutment between the stepped surface 24 and the stepped matching surface 32 not only limits the insertion depth of the cover 30 inserted into the water inlet 21, but also ensures the sealing performance of the water inlet 21 when the cover 30 is assembled on the upper cover 20. Here, the number of stepped surfaces 24 is two, and a height difference is formed between the two stepped surfaces 24. It can be understood that in other embodiments, the number of stepped surfaces 24 can also be one, three, or even more, which will not be described here.
[0052] As shown in Figure 2 , Figure 3 , and Figure 6As shown, the lid 30 has an outer end surface 33; when the lid 30 is connected to the upper cover 20, the outer end surface 33 is arranged on the same surface as the upper cover outer peripheral wall 25 of the upper cover 20, and specifically can be arranged on the same arc surface. That is, the lid 30 does not protrude outward relative to the upper cover 20 when assembled on the upper cover 20, which can improve the continuity of the appearance of the lid 30 when assembled on the upper cover 20, and ensure the overall external aesthetic appearance of the refrigeration preservation box 100.
[0053] In addition, the present application also provides a refrigerator comprising the refrigeration preservation box 100 described above.
[0054] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.
[0055] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation of the present application. Any appropriate changes and variations to the above embodiments, as long as they fall within the spirit and scope of the present application, are within the scope of the present application.
