Description

Technical Field

[0001] This invention relates to the field of refrigeration and storage equipment, and particularly to a decondensation plate assembly, a preservation device, and a refrigerator. Background Technology

[0002] Most refrigerators are equipped with a crisper drawer, which is usually connected to the refrigerator compartment. This type of refrigerator will dry out the food in the crisper drawer to some extent. Therefore, some refrigerator products choose to have a crisper compartment to reduce the convection between the crisper compartment and the outside refrigerator compartment, which can play a role in keeping food fresh. However, fruits and vegetables have the function of respiration and transpiration, which will produce moisture. When the moisture adheres to the inner wall of the crisper compartment and accumulates to a certain extent, the moisture will condense into condensation and drip onto the fruits and vegetables. Over time, this will cause the fruits and vegetables to be soaked in water, which will accelerate the spoilage of the fruits and vegetables. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a dew-removing plate assembly, which can effectively remove condensation, thereby extending the shelf life of food.

[0004] The present invention also proposes a preservation device having the above-mentioned decondensation plate assembly and a refrigerator having the preservation device.

[0005] According to a first aspect of the present invention, a dew-removing plate assembly includes: a dew-removing plate having a plurality of dew-removing holes, the dew-removing plate having a first surface and a second surface, the two ends of the dew-removing holes penetrating the first surface and the second surface, the dew-removing holes including a water-collecting section, the end of the water-collecting section near the first surface being a first end, the end of the water-collecting section near the second surface being a second end, the cross-sectional area of ​​the first end being smaller than the cross-sectional area of ​​the second end; and a baffle configured to generate airflow on the first surface.

[0006] The dew-removing plate assembly according to embodiments of the present invention has at least the following beneficial effects:

[0007] Moisture from the transpiration of fruits and vegetables adheres to the dew-collecting plate. The plate has several dew-collecting holes with water collection sections. Because the cross-sectional area of ​​the first end of each water collection section is smaller than that of the second end, the water collection section increases the contact area between the dew-collecting holes and the water, allowing more water to adhere to the collection section. It should be noted that the airflow baffle creates an airflow on the first surface of the dew-collecting plate. This airflow evaporates the moisture adhering to the dew-collecting holes, preventing condensation and thus preventing the food from being soaked in water, extending its shelf life. Furthermore, since the airflow baffle only creates airflow on the first surface of the dew-collecting plate, it does not accelerate the evaporation of moisture from the food itself, but primarily evaporates the moisture adhering to the dew-collecting plate. Therefore, the dew-collecting plate assembly of this invention also serves a moisturizing function.

[0008] According to some embodiments of the present invention, the water collection section is conical.

[0009] According to some embodiments of the present invention, the dew outlet further includes a ventilation section, one end of which is connected to the first end, and the other end of which penetrates the first surface.

[0010] According to some embodiments of the present invention, the ventilation section is cylindrical, and the inner diameter of the ventilation section is equal to the inner diameter of the first end.

[0011] According to some embodiments of the present invention, the baffle has an air outlet, the air outlet is disposed in contact with the first surface, and the air outlet direction is parallel to the first surface.

[0012] According to a second aspect of the present invention, a preservation device is formed inside, the preservation device including the decondensation plate assembly described in the above embodiments, the decondensation plate being disposed within the preservation space.

[0013] The preservation device according to embodiments of the present invention has at least the following beneficial effects:

[0014] The preservation space can be used to hold fruits, vegetables, and other food items. A decondensation plate assembly can be installed within the preservation space. Water generated by the transpiration of fruits, vegetables, and other food items placed within the preservation space adheres to the decondensation plate. The decondensation plate has several decondensation holes with water collection sections. Because the cross-sectional area of ​​the first end of the water collection section is smaller than that of the second end, the water collection section increases the contact area between the decondensation holes and the water, thus allowing more water to adhere to the water collection section. It is understood that the airflow baffles installed within the preservation space can create airflow on the first surface of the decondensation plate. This airflow evaporates the water adhering to the decondensation holes, thereby preventing condensation and preventing the food from being soaked in water, and extending the shelf life of the food. Furthermore, since the airflow baffles only create airflow on the first surface of the decondensation plate, they do not accelerate the evaporation of water from the food within the preservation space, but mainly evaporate the water adhering to the decondensation plate. Therefore, the preservation device with a decondensation plate assembly in this invention can both decondense and retain moisture.

[0015] According to some embodiments of the present invention, the second end of the water collection section faces the interior of the preservation space.

[0016] According to some embodiments of the present invention, the decondensation plate is horizontally disposed at the top of the preservation space, and there is a flow gap between the decondensation plate and the top wall of the preservation space, the flow gap being able to allow airflow.

[0017] According to some embodiments of the present invention, the dehumidifier plate is provided with screw posts, which can be connected to the top wall of the preservation space to form the flow gap.

[0018] According to some embodiments of the present invention, the turbulence element is a fan, which is disposed on the dew plate and located within the flow gap.

[0019] A refrigerator according to a third aspect of the present invention includes the preservation device described in the above embodiments.

[0020] The refrigerator according to an embodiment of the present invention has at least the following beneficial effects:

[0021] A refrigerator equipped with the aforementioned preservation device can be used to store fruits, vegetables, and other food items. The preservation device forms a preservation space, and a decondensation plate assembly can be installed within this space. Moisture generated by the transpiration of fruits, vegetables, and other food items placed within the preservation space adheres to the decondensation plate. The decondensation plate has several decondensation holes with water collection sections. Since the cross-sectional area of ​​the first end of the water collection section is smaller than that of the second end, the water collection section increases the contact area between the decondensation holes and the water, thus allowing more water to adhere to the water collection section. It is understood that the airflow deflector located within the preservation space can create airflow on the first surface of the decondensation plate. This airflow evaporates the moisture adhering to the decondensation holes, preventing condensation and thus preventing the food from being soaked in water, extending the shelf life of the food. Furthermore, since the airflow deflector only creates airflow on the first surface of the decondensation plate, it does not accelerate the evaporation of moisture from the food within the preservation space, but primarily evaporates the moisture adhering to the decondensation plate. Therefore, the refrigerator with the above-mentioned preservation device in this invention can both decondense and retain moisture.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0040] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or the order in which the indicated technical features are presented.

[0041] In the description of this invention, unless otherwise explicitly defined, terms such as setting, installing, connecting, and docking should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0042] Reference Figures 1 to 8 The present invention discloses a decondensation plate assembly 200. The decondensation plate assembly 200 in the embodiments of the present invention is applicable to refrigeration storage equipment, including but not limited to refrigerators, freezers and refrigerated cabinets.

[0043] like Figure 1 and Figure 2As shown, the dew plate assembly 200 in this embodiment of the invention can promote the evaporation of condensation adhering to the dew plate 300, thereby preventing the stored food from being soaked by dripping condensation and thus extending the shelf life of the food.

[0044] Understandably, referring to Figures 2 to 4 The dew-removing plate assembly 200 in this embodiment of the invention includes a dew-removing plate 300 and a fan 400. The dew-removing plate 300 has a first surface 310 and a second surface 320, and the dew-removing plate 300 has a plurality of dew-removing holes 330. The dew-removing holes 330 are disposed through the dew-removing plate 300, that is, both ends of the dew-removing holes 330 penetrate through the first surface 310 and the second surface 320. The fan 400 can be configured to generate airflow on the first surface 310. It is understood that when the airflow flows through the dew-removing holes 330 penetrating the dew-removing plate 300, it will carry away the moisture at the location of the dew-removing holes 330, thereby promoting the evaporation of moisture on the dew-removing plate 300.

[0045] It should be noted that, referring to Figure 5 and Figure 6 The dew-collecting orifice 330 includes a water-collecting section 331. The end of the water-collecting section 331 near the first surface 310 is designated as the first end 3311, and the end near the second surface 320 is designated as the second end 3312. The cross-sectional area of ​​the first end 3311 is smaller than that of the second end 3312. The water-collecting section 331 increases the contact area between the dew-collecting orifice 330 and water, allowing more water to adhere to its position. It is understood that when more water adheres to the surface of the water-collecting section 331 of the dew-collecting orifice 330, the probability of water condensing and forming condensation is reduced, further contributing to preservation. It is also understood that the end of the water-collecting section 331 near the second surface 320 can penetrate through the second surface 320. Furthermore, since the fan 400 only forms airflow on the first surface 310 of the dew plate 300, the fan 400 does not accelerate the evaporation of moisture from the food. The airflow only carries away the moisture adhering to the dew holes 330 through each dew hole 330. Therefore, the dew plate assembly 200 in this invention can also play a moisturizing role. The cross-sectional area of ​​the water collection section 331 mentioned above refers to the cross-sectional area perpendicular to the axial direction of the water collection section 331.

[0046] Reference Figure 3 and Figure 4In this embodiment of the invention, the plurality of dew-removing holes 330 on the dew-removing plate 300 can be arranged in an array, including but not limited to a square array or a circular array, or they can be distributed randomly. It should be noted that since the second surface 320 is planar, moisture adhering to the planar surface is not easily evaporated by the airflow at the dew-removing holes 330. However, if moisture adheres to the water collection section 331 on the dew-removing hole 330, it is more easily evaporated by the airflow generated by the fan 400. Therefore, the plurality of dew-removing holes 330 can be arranged in a denser configuration so that the water collection sections 331 on each dew-removing hole 330 can be as close to each other as possible, thereby reducing the area of ​​the second surface 320. Furthermore, the plurality of dew-removing holes 330 can be arranged as densely as possible on the entire dew-removing plate 300 to cover more areas where condensation may occur on the food.

[0047] It is understood that the fan 400 in the embodiment of the present invention can be set to one, but when the area of ​​the dew plate 300 is large, the airflow generated by one fan 400 may not be able to cover the location of each dew hole 330. Therefore, the fan 400 can also be set to multiple.

[0048] Reference Figure 6 The cross-sectional area of ​​the water collecting section 331 gradually increases from the first surface 310 to the second surface 320. The inner surface of the water collecting section 331 can be an arc surface, a plane, or even a curved surface, as long as the water collecting section 331 can be tilted at a certain angle relative to the second surface 320 to increase the contact area between the water collecting section 331 and the water. It is understood that, for ease of processing and cleaning during use, the water collecting section 331 in this embodiment is set in a conical shape. It should be noted that the conical shape of the water collecting section 331 can be a cone or a pyramid, or it can include the following shapes: at least one surface of the water collecting section 331 is tilted at a certain angle to the second surface 320, and the remaining surfaces are perpendicular to the second surface 320.

[0049] The slope of the water collection section 331 also allows the airflow generated by the fan 400 to increase the contact area between the water collection section 331 and the airflow when it flows into the water collection section 331 from the first surface 310, compared to the second plane 320, which further allows the water adhering to the water collection section 331 to evaporate faster.

[0050] It is understandable that when the water collection section 331 is conical, the angle between the inner surface of the water collection section 331 and the second surface 320 in this embodiment of the invention can be set to greater than or equal to 45 degrees and less than or equal to 60 degrees. If the angle is too large, the inner surface of the water collection section 331 will be closer to being perpendicular to the second surface 320. After water adheres to the surface of the water collection section 331, it is easy for it to slide down under its own gravity. This may result in the water condensing into condensation before the airflow generated by the fan 400 can evaporate the water. In addition, if the angle between the inner surface of the water collection section 331 and the second surface 320 is too small, the surface area of ​​the water collection section 331 will be closer to the area of ​​the projected area of ​​the water collection section 331 on the second surface 320. The amount of water that can adhere to the water collection section 331 will also be reduced, which is not conducive to the preservation of food.

[0051] In addition, the dew removal hole 330 in this embodiment of the invention also includes a ventilation section 332. One end of the ventilation section 332 is connected to the first end 3311, and the other end of the ventilation section 332 penetrates the first surface 310. The ventilation section 332 can guide the airflow generated by the fan 400, guide the airflow to flow out along the ventilation section 332, and make the airflow evaporate the moisture at the dew removal hole 330.

[0052] It should be noted that, referring to Figure 7 When the decondensation hole 330 does not include the ventilation section 332, the first end 3311 of the water collection section 331 can directly penetrate the first surface 310. The airflow generated by the fan 400 will directly flow into the decondensation hole 330 at the first end 3311 of the water collection section 331 and evaporate the moisture. It can be understood that since the cross-sectional area of ​​the first end 3311 of the water collection section 331 is smaller than the cross-sectional area of ​​the second end 3312 of the water collection section 331, the airflow generated by the fan 400 will only flow through the first end 3311 of the water collection section 331 towards the second surface 320 of the decondensation plate 300, without causing a large area of ​​airflow. Therefore, the moisture of the food can be maintained while achieving decondensation.

[0053] Reference Figure 2 Regardless of whether the fan 400 is configured to supply air with its outlet 410 parallel to the first surface 310, or to supply air with its outlet 410 perpendicular to or at a certain angle to the first surface 310, it can promote the evaporation of moisture within the dew removal hole 330. It should be noted that in this embodiment of the invention, the fan 400 can be configured such that the air outlet 410's outlet direction is parallel to the first surface 310, and the lower end of the outlet 410 is on the same plane as the first surface 310, which can increase the contact area between the airflow generated by the fan 400 and the first surface 310.

[0054] It should be noted that when the fan 400 is configured to send air out through the outlet 410 towards the decondensation plate 300, the airflow from the outlet 410 will flow out through the decondensation hole 330. When the outlet 410 of the fan 400 is configured to send air parallel to the first surface 310 of the decondensation plate 300, if the fan speed is low, the airflow generated by the fan 400 can flow out through the decondensation hole 330. If the fan speed is high, the airflow generated by the fan 400 may not have enough time to flow out through the decondensation hole 330. However, the airflow generated by the fan 400 will generate negative pressure at the end of the decondensation hole 330 near the first surface 310. This causes the water adhering to the water collection section 331 of the decondensation hole 330 to be carried away and evaporated by the airflow. At the same time, under the negative pressure generated by the airflow, the water will gradually move towards the end of the water collection section 331 near the first surface 310, which can also accelerate the evaporation of water and prevent condensation.

[0055] like Figure 6 As shown, the ventilation section 332 in this embodiment of the invention can be configured as a cylindrical structure, including but not limited to cylindrical holes or prismatic holes. When the fan 400 has a large airflow and generates negative pressure on the first surface 310, the airflow generated by the fan 400 will flow from the second surface 320 towards the first surface 310. In order to allow the water adhering to the water collection section 331 to climb up along the inclined inner wall of the water collection section 331 into the ventilation section 332, the size of the ventilation section 332 can be set to be equal to the size of the first end 3311 of the water collection section 331. At this time, the end of the ventilation section 332 near the second surface 320 and the first end 3311 of the water collection section 331 can be smoothly transitioned through rounded corners or other means. When the ventilation section 332 is a cylindrical hole and the water collection section 331 is a conical hole, the inner diameter of the ventilation hole 332 can be set to be equal to the inner diameter of the first end 3311 of the water collection section 331.

[0056] In this embodiment of the invention, the inner diameter of the ventilation section 332 should be set as small as possible to reduce the airflow generated by the fan 400 from the ventilation section 332, so that the airflow from the ventilation section 332 can only evaporate the water attached to the water collection section 331, and will not cause the food to lose moisture. It should be noted that the inner diameter of the ventilation section 332 can be set to less than or equal to 1 mm, such as 0.5 mm or 0.8 mm.

[0057] One embodiment of the present invention discloses a preservation device with an internal preservation space 100 for holding fruits, vegetables, and other food ingredients. The device includes a dehumidifier plate assembly 200 as described in the previous embodiment. A dehumidifier plate 300 is disposed within the preservation space 100. The dehumidifier plate assembly 200 allows moisture evaporated from the food ingredients to adhere to the dehumidifier plate 300, which is then evaporated by a fan 400. The dehumidifier plate 300 has several dehumidifier holes 330 with water collection sections 331. Because the cross-sectional area of ​​the first end 3311 of the water collection section 331 is smaller than that of the second end 3312, the water collection section 331 increases the contact area between the dehumidifier holes 330 and the water, thus allowing more moisture to adhere to the water collection section 331. It is understood that the fan 400 installed in the preservation space 100 can generate airflow on the first surface 310 of the dew plate 300. This airflow evaporates the moisture attached to the dew holes 330, thereby preventing moisture from condensing into condensation, thus preventing the food from being soaked in water, and extending the shelf life of the food. In addition, since the fan 400 only generates airflow on the first surface 310 of the dew plate 300, the fan 400 does not accelerate the evaporation of moisture from the food in the preservation space 100, but mainly evaporates the moisture attached to the dew plate 300. Therefore, the preservation device in this invention can also play a role in moisturizing.

[0058] The preservation device can be an independent refrigerated compartment within a refrigeration storage device, or a preservation drawer within a refrigerated compartment. It is understood that, for the preservation space 100 as a whole, the preservation space 100 can seal the moisture of the food inside. However, for the food itself, although the moisture inside the food does not escape outside the preservation space 100, it will evaporate into areas within the preservation space 100 other than the food itself due to its own transpiration. Over time, this evaporated moisture will adhere to the inner wall of the preservation space 100 and condense into condensation. To prevent condensation from dripping and soaking the food, the decondensation plate assembly 200 can be installed inside the preservation space 100 as described above, so that the evaporated moisture can adhere to the decondensation plate 300 within the decondensation plate assembly 200. For example, the decondensation plate assembly 200 can be installed in areas within the preservation space 100 where condensation is more concentrated.

[0059] The aforementioned preservation space 100 includes, but is not limited to, a refrigerator compartment or a preservation drawer in a refrigeration storage device. To further enhance the preservation of food, the preservation space 100 may also be configured to be sealed. It is understood that the sealed state of the preservation space 100 does not mean that the preservation space 100 is always sealed. When a user retrieves food from the preservation space 100, the preservation space 100 will be opened for user access. Therefore, the sealed preservation space 100 referred to here means that the preservation space 100 can be in a sealed state. It should be noted that... Figure 1 In order to facilitate understanding, one side wall of the preservation space 100 is hidden so as to make it easier to observe the dehumidifier assembly 200 located in the preservation space 100.

[0060] It should be noted that, as Figure 1 As shown, the de-condensation plate 300 can be placed in the preservation space 100 at any position and angle. If the first surface 310 of the de-condensation plate 300 is positioned towards the food, and the fan 400 generates airflow over the first surface 310, but this airflow cannot be limited to the vicinity of the first surface 310 (e.g., the airflow causes air circulation around the food), the airflow will accelerate the evaporation of moisture from the food. To prevent this accelerated evaporation, the airflow generated by the fan 400 needs to be controlled to flow only near the first surface 310 of the de-condensation plate 300, or the first surface 310 of the de-condensation plate 300 can be positioned away from the food. In this embodiment, the de-condensation plate 300 can be configured such that the water collection section 331 faces the interior of the preservation space 100, i.e., the water collection section 331 faces the food, allowing the water collection section 331 to collect more moisture.

[0061] Reference Figure 1 The decondensation effect of the decondensation plate assembly 200 can be accelerated by placing the decondensation plate 300 horizontally on top of the preservation space 100. It is understood that the decondensation plate 300 can be horizontally positioned at a position above half the vertical length within the preservation space 100. To maximize the space available for food within the preservation device, the decondensation plate 300 can also be positioned as close as possible to the upper surface of the preservation space 100. A flow gap 600 is formed between the decondensation plate 300 and the top wall of the preservation space 100, allowing airflow generated by the fan 400 to pass through.

[0062] It is understood that the dew-removing plate 300 in the embodiments of the present invention can itself serve as the top wall or side wall of the preservation space 100. In this case, the second surface 320 of the dew-removing plate 300 can be set to face the interior of the preservation space 100, so that the water collection section 331 faces the direction of the food in the preservation space 100. The fan 400 can be set on the first surface 310 of the dew-removing plate 300 or on the exterior of the preservation space 100.

[0063] When the fan 400 blows air onto the first surface 310, after the airflow passes through the first surface 310, part of the airflow will flow out through each decondensation hole 330, and the remaining airflow can flow out through the gap between the edge of the decondensation plate 300 and the inner wall of the preservation space 100. To further reduce the circulation of air within the preservation space 100 by the fan 400 and prevent excessive moisture loss from the food, the edge of the decondensation plate 300 in this embodiment can be set as close as possible to the inner wall of the preservation space 100 to minimize the airflow from the gap between the edge of the decondensation plate 300 and the inner wall of the preservation space 100. Alternatively, the decondensation plate 300 can be set to fit against the inner wall of the preservation space 100. In this case, the air inlet of the fan 400 can draw in air from some of the decondensation holes 330, and the air outlet 410 of the fan 400 can deliver airflow to another part of the decondensation holes 330. However, regardless of whether the decondensation holes 330 are receiving airflow or are receiving airflow, the moisture attached to each decondensation hole 330 can come into contact with the airflow and evaporate.

[0064] In this embodiment of the invention, the fan 400 can work in conjunction with a humidity sensor (not shown in the figure). The humidity sensor can be placed inside the preservation space 100 to detect the humidity of the air inside the preservation space 100. The humidity sensor can transmit the humidity information to the control unit. When the humidity detected by the humidity sensor reaches a certain preset value, the control unit can control the fan 400 to start or stop, thereby realizing intermittent air supply by the fan 400. It can be understood that the humidity sensor can be placed on the second surface 320 so that the humidity sensor can more accurately monitor the air humidity near the dew hole 330, thereby enabling timely evaporation of moisture adhering to the dew hole 330.

[0065] It should be noted that the intermittent start-up of the fan 400 can also be controlled by setting the operating time of the fan 400. For example, the operating time and stop time of the fan 400 can be preset according to the speed at which the food in the preservation space 100 evaporates moisture.

[0066] Reference Figure 2 In this embodiment of the invention, the fan 400 can be an axial flow fan, a centrifugal fan, a cross-flow fan, etc. The fan 400 can be disposed within the flow gap 600. When the fan 400 in this embodiment of the invention is a centrifugal fan, the centrifugal fan can be fixed on the first surface 310 of the dew plate 300, and the lower end of the outlet 410 of the centrifugal fan can be attached to the first surface 310 of the dew plate 300. The outlet 410 of the centrifugal fan can be closer to or even attached to the dew plate 300, thus increasing the contact area between the airflow and the first surface 310 of the dew plate 300 to a greater extent.

[0067] Reference Figure 8In this embodiment of the invention, the fan 400 can be installed on the first surface 310 of the de-condensation plate 300 and located within the flow gap 600 between the first surface 310 and the top of the preservation space 100. The fan 400 can be fixed by a mounting base 500 provided on the first surface 310. The mounting base 500 includes a buckle 510. During installation, simply fasten the fan 400 to the buckle 510. The installation is simple and reliable. Of course, the fan 400 can also be fixed to the de-condensation plate 300 with fasteners. It should be noted that the de-condensation plate 300 and the preservation device can be connected by fasteners. Multiple screw posts 340 can be provided on the de-condensation plate 300. During installation, simply connect the de-condensation plate 300 to the top wall of the preservation device at the positions of each screw post 340 using fasteners. The screw posts 340 can form a flow gap 600 between the de-condensation plate 300 and the top of the preservation space 100.

[0068] The refrigerator in this embodiment of the invention is equipped with the preservation device described in the above embodiments. The refrigerator includes, but is not limited to, single-door, double-door, or other multi-door refrigerators. When the refrigerator door is opened, the user can place food into the preservation device. When the preservation device is an independent refrigerator compartment within the refrigeration storage equipment, closing the refrigerator door allows the preservation device to form a preservation space 100; when the preservation device is a closable preservation drawer within the refrigerator's refrigerator compartment, closing the drawer allows the preservation device to form a preservation space 100. A refrigerator equipped with the above-mentioned preservation device can extend the shelf life of the food inside and maintain the humidity within the preservation device.

[0069] Understandably, multiple preservation devices can be installed inside the refrigerator, and multiple decondensation plate assemblies 200 can also be installed inside the preservation devices.

[0070] It should be noted that the fan 400 in this embodiment of the invention can also be replaced by a deoxygenation module or other airflow-damping components. For example, when a deoxygenation module is used instead of the fan 400, the deoxygenation module can be at least partially disposed outside the preservation space 100. The preservation space 100 can have ventilation openings, and the deoxygenation module can contact the air inside the preservation space 100 through the ventilation openings, so that the oxygen in the air reacts with the deoxygenation module and is replaced to the outside of the preservation space 100, thereby forming a low-oxygen negative pressure environment inside the preservation space 100. This low-oxygen negative pressure environment can generate airflow inside the preservation space 100. If the position of the deoxygenation module corresponds to the decondensation plate 300, the airflow generated by the negative pressure can evaporate the moisture attached to the decondensation plate 300, realizing the decondensation process.

[0071] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
