DETAILED DESCRIPTION

[0029] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Combine Figure 1 According to the fresh-keeping container 100 of the embodiment of the present invention, a storage cavity 10 is provided in the fresh-keeping container 100. The storage cavity 10 can be used to store food. A separation structure 11 is provided at the bottom of the storage cavity 10. The separation structure 11 is configured to place materials. For example, food can be placed on the separation structure 11, and the separation structure 11 can separate water located on the upper surface of the separation structure 11. Specifically, when food is placed in the storage cavity 10, the food itself may contain moisture, and the food will evaporate moisture during the preservation process. By providing the separation structure 11 at the bottom of the storage cavity 10, the food is placed on the separation structure 11, and the moisture on the food can flow to the bottom of the storage cavity 10 under the action of gravity, which makes it easier to keep the food dry, avoids moisture accumulation on the food, and causes the food to rot, thereby improving the preservation effect.

[0031] According to the fresh-keeping container 100 of the embodiment of the present invention, by providing the separation structure 11, a dry environment above the separation structure 11 can be maintained, thereby preventing moisture from accumulating on the material and improving the fresh-keeping effect.

[0032] Among them, the separation structure 11 can be set to different structures. For example, a plurality of protrusions can be provided on the bottom wall of the storage cavity 10, and the plurality of protrusions constitute the separation structure 11. The moisture of the food during the storage process can flow to the bottom wall of the storage cavity 10 under the action of gravity, and the separation of the food and the moisture can be achieved through the separation structure 11; or, a water-absorbing layer is provided at the bottom of the storage cavity 10, and the water-absorbing layer can be formed into the separation structure 11, which can absorb the moisture above it through the water-absorbing layer to maintain a dry environment in the storage cavity 10; or, the separation structure 11 can be a porous plate 13 structure, etc.

[0033] In addition, the separation structure 11 separates the water located on the upper surface of the separation structure 11, and the water can flow to the bottom of the storage cavity 10. A space for collecting water can be set at the bottom of the storage cavity 10 to facilitate the isolation of water from food and ensure the dryness of food; or, a drain outlet can be provided at the bottom of the storage cavity 10, through which the water under the separation structure 11 can be discharged; or, a water absorbent can be provided at the bottom of the storage cavity 10, through which the water under the separation structure 11 can be absorbed.

[0034] For example, the fresh-keeping container 100 can be a refrigerator drawer, a refrigerator vacuum drum, etc. It is understood that when the fresh-keeping container 100 is used in a closed environment, the food easily releases moisture, which cannot be discharged. This can easily lead to moisture accumulation on the food, causing the food to rot and breed bacteria. By providing a separation structure at the bottom of the storage cavity 10, the moisture in the closed environment can be effectively separated, thereby improving the freshness of the food.

[0035] Combine Figure 1 and Figure 2 In some embodiments of the present invention, the separation structure 11 constructs a water accumulation space 12 at the bottom of the storage chamber 10. The water accumulation space 12 is used to store water located on the upper surface of the separation structure 11. By providing the water accumulation space 12, it is convenient to separate the water from the material above the separation structure 11, and it is convenient for regular cleaning and maintenance.

[0036] In some embodiments of the present invention, a boss is provided on the bottom wall of the storage chamber 10, and the boss is configured as a separation structure 11. At least a portion of the water accumulation space 12 is located between the periphery of the boss and the peripheral wall of the storage chamber 10. Providing the boss on the bottom wall of the storage chamber 10 simplifies the separation structure 11, facilitating the processing and forming of the fresh-keeping container 100. The water accumulation space 12 can be entirely located between the periphery of the boss and the peripheral wall of the storage chamber 10. For example, the bottom wall of the storage chamber 10 can be provided with a boss, and the water accumulation space 12 is formed between the outer periphery of the boss and the peripheral wall of the storage chamber 10, so that the water accumulation space 12 can effectively collect the water separated by the boss. Alternatively, a portion of the water accumulation space 12 can be located between the periphery of the boss and the peripheral wall of the storage chamber 10. For example, the bottom wall of the storage chamber 10 can be provided with multiple bosses, and a portion of the water accumulation space 12 can be located between the multiple bosses.

[0037] The water accumulation space 12 can be provided around the separation structure 11 so that the water accumulation space 12 can effectively collect the water separated by the separation structure 11. For example, the water accumulation space 12 can be an annular groove provided around the separation structure 11, which can simplify the structure of the fresh-keeping container 100 and facilitate cleaning of the water accumulation space 12.

[0038] In some embodiments of the present invention, the bottom wall of the storage cavity 10 is provided with a plurality of bosses, and the plurality of bosses are configured to form a separation structure 11. By providing a plurality of bosses, the moisture separation efficiency of the material on the separation structure 11 is improved, and moisture accumulation between the materials is avoided. At least a portion of the water accumulation space 12 is located between the plurality of bosses, which is convenient for collecting the separated moisture, keeping the food dry, and further improving the preservation effect.

[0039] Furthermore, the periphery of the boss is connected to the inner surface slope of the water accumulation space 12, and the slope can form a guide surface to facilitate the diversion of water above the boss into the water accumulation space 12, thereby avoiding the accumulation of water above the boss and improving the separation effect of the separation structure 11 on water.

[0040] Combine Figure 3 In some embodiments of the present invention, a perforated plate 13 is provided at the bottom of the storage chamber 10. The perforated plate 13 is configured as a separation structure 11. The perforated plate 13 is provided with a plurality of water collection holes 131. The water collection holes 131 extend through the upper surface of the perforated plate 13 and form a water collection space 12. Specifically, the perforated plate 13 can be provided at the bottom of the storage chamber 10. When food is placed above the perforated plate 13, moisture from the food or moisture generated during storage can be collected in the plurality of water collection holes 131 under the action of gravity.

[0041] Among them, the water accumulation hole 131 can pass through the upper surface of the perforated plate 13, that is, the water accumulation hole 131 can be a blind hole. In this case, the moisture on the food or the moisture generated during the storage process can be directly collected in the water accumulation hole 131; or, the water accumulation hole 131 can be a through hole, that is, the water accumulation hole 131 passes through the upper surface and the lower surface of the perforated plate 13. At this time, the water accumulation hole 131 and the bottom of the storage cavity 10 can jointly construct a water accumulation space 12.

[0042] The perforated plate 13 and the storage cavity 10 may be a split structure, or the perforated plate 13 may be detachable from the storage cavity 10. By providing the perforated plate 13, it is convenient to maintain a dry environment for food in the storage cavity 10 and to facilitate regular cleaning and maintenance of the perforated plate 13.

[0043] In some embodiments of the present invention, a gap is provided between the lower surface of the orifice plate 13 and the inner bottom surface of the storage cavity 10, and the water accumulation hole 131 passes through the lower surface of the orifice plate 13, and the gap connects multiple water accumulation holes 131. In other words, the water accumulation hole 131 can be a through hole, and water above the orifice plate 13 can enter between the orifice plate 13 and the storage cavity 10 through the water accumulation hole 131, so as to enhance the isolation effect of moisture, avoid contact between moisture and food, and maintain a dry environment for food in the storage cavity 10.

[0044] The water accumulation hole 131 can be set to different shapes. For example, it can be a circular hole, a long strip hole, etc.

[0045] A gap is provided between the lower surface of the orifice plate 13 and the inner bottom surface of the storage cavity 10. For example, a support portion may be provided below the orifice plate 13, which can support the orifice plate 13 and form a gap between the orifice plate 13 and the inner bottom edge of the storage cavity 10, so as to isolate moisture from food; or, a support portion is provided on the inner bottom surface of the storage cavity 10, and the orifice plate 13 is supported by the support portion, thereby improving the structural stability of the orifice plate 13 and facilitating the construction of a certain space below the orifice plate 13, so as to isolate the moisture separated by the orifice plate 13.

[0046] In addition, the water accumulation space 12 can be provided around the outer periphery of the orifice plate 13 , so that the water separated by the orifice plate 13 can be effectively received by the water accumulation space 12 .

[0047] In some embodiments of the present invention, a water-absorbing layer is provided at the bottom of the storage chamber 10, and the water-absorbing layer is configured as a separation structure 11. For example, the water-absorbing layer can be a water-absorbing material such as diatom mud. When food is placed above the water-absorbing layer, moisture from the food itself or moisture released by the food drips onto the water-absorbing layer under the action of gravity and is absorbed by the water-absorbing layer, thereby maintaining a dry environment within the storage chamber 10 and improving the fresh-keeping effect of the fresh-keeping container 100.

[0048] Combine Figure 4 In some embodiments of the present invention, the fresh-keeping container 100 includes: a sealed barrel 20 and a drawer 30. The sealed barrel 20 is provided with a storage space, and the side of the storage space is open; the drawer 30 can be pulled out to pass through the opening and extend into the storage space. A storage cavity 10 is constructed in the drawer 30, and a separation structure 11 is provided at the bottom of the drawer 30. Specifically, the storage cavity 10 can be opened and closed by pulling out the drawer 30, which makes it convenient to store food in the storage cavity 10 or take food out of the storage cavity 10. After the drawer 30 is loaded into the storage space, it can be sealed by the sealed barrel 20 to maintain a stable environment in the storage space. It is understandable that in a closed space, food is prone to volatilization of moisture and forming water droplets, especially leafy vegetables, which are prone to rot. By providing the separation structure 11, the moisture on the food can be effectively separated, thereby improving the preservation effect of the food.

[0049] The drawer 30 and the sealed barrel 20 may be provided with sealing strips to improve the sealing effect between the drawer 30 and the sealed barrel 20. The sealed barrel 20 may also be provided with a locking mechanism, which can lock the drawer 30 to the sealed barrel 20 after the drawer 30 is loaded into the sealed barrel 20, thereby improving the sealing effect of the fresh-keeping volume.

[0050] Combine Figure 4Furthermore, the fresh-keeping container 100 is provided with an exhaust port 40 for connecting to an exhaust device, and the exhaust port 40 is connected to the storage chamber 10. Specifically, the exhaust port 40 can be used to extract the gas in the storage chamber 10, maintaining the storage chamber in a low-pressure, low-oxygen state, effectively inhibiting the respiration of the food and maintaining the freshness of the food. By providing the aforementioned separation structure 11, the moisture evaporated by the food in the vacuum space can be separated from the food through the separation structure 11, preventing the food from being soaked in water, which may cause food rot and breed bacteria, further improving the freshness of the fresh-keeping container 100.

[0051] Optionally, the sealed barrel 20 may have a first end and a second end, with the opening arranged at the first end. The peripheral wall of the sealed barrel 20 is provided with a plurality of first reinforcing ribs, which are distributed from the first end to the second end. This can improve the structural strength of the fresh-keeping container 100 and prevent the fresh-keeping container 100 from deforming under low pressure, thereby improving the sealing performance of the fresh-keeping container 100.

[0052] Among them, the density of the arrangement of multiple first reinforcing ribs near the first end is greater than the density near the second end; the first end of the sealed barrel 20 is provided with an opening, which can facilitate the user to put food into the sealed barrel 20 and take food out of the sealed barrel 20; after the sealed barrel 20 is evacuated, the opening of the sealed barrel 20 will also be deformed inwardly by the pressure difference. At this time, the density of the arrangement of multiple first reinforcing ribs near the first end can be greater than the density near the second end, so as to improve the structural strength of the opening of the sealed barrel 20 and avoid the opening of the sealed barrel 20 from deforming inwardly due to the pressure difference, thereby affecting the sealing performance of the fresh-keeping container 100; it can be understood that the sealed barrel 20 includes a first part near the first end and a second part near the second end, and the first part and the second part are both provided with multiple first reinforcing ribs, and the number of first reinforcing ribs per unit area of ​​the first part is greater than the number of first reinforcing ribs per unit area of ​​the second part, that is, the density of the multiple first reinforcing ribs in the first part is greater than the density of the multiple first reinforcing ribs in the second part, thereby improving the structural strength of the opening of the sealed barrel 20.

[0053] Optionally, the peripheral wall of the sealed barrel 20 is provided with a plurality of second reinforcing ribs, the plurality of second reinforcing ribs are distributed in a direction around the axis of the opening, and the second reinforcing ribs are staggered with the first reinforcing ribs; specifically, the fresh-keeping container 100 can preserve food by using vacuum preservation technology, and the sealed barrel 20 of the fresh-keeping container 100 can be provided with a plurality of first reinforcing ribs and a plurality of second reinforcing ribs, the plurality of first reinforcing ribs are distributed from the first end to the second end, and the plurality of second reinforcing ribs are distributed in a direction around the axis of the opening, and the second reinforcing ribs are staggered with the first reinforcing ribs, which can improve the structural strength of the fresh-keeping container 100 in multiple directions, avoid deformation of the fresh-keeping container 100 when under low pressure, and thereby improve the sealing performance of the fresh-keeping container 100.

[0054] Combine Figure 5The present invention further provides a fresh-keeping device 1000, comprising: the aforementioned fresh-keeping container 100 and an air extraction assembly 200, the air extraction assembly 200 being connected to the storage chamber 10 and configured to generate a negative pressure within the storage chamber 10. For example, the air extraction assembly 200 may include a vacuum pump and an air pipe, which may be connected to the storage chamber 10. The air extraction assembly 200 may be used to extract some of the gas within the storage chamber 10, creating a low-oxygen, low-pressure environment within the storage chamber 10, thereby improving the fresh-keeping effect of the fresh-keeping device 1000.

[0055] The present invention also provides a low-temperature fresh-keeping device, comprising: a housing, a refrigeration device, and the aforementioned fresh-keeping device 1000. The housing is provided with a refrigeration compartment. The refrigeration device is mounted on the housing and used to cool the refrigeration compartment; the fresh-keeping device 1000 is mounted within the refrigeration compartment. By installing the aforementioned fresh-keeping device 1000, moisture in the food itself or moisture generated during the fresh-keeping process can be separated, preventing the food from being soaked in water and affecting the fresh-keeping effect of the food, thereby improving the fresh-keeping effect of the low-temperature fresh-keeping device.
