Abstract
Description
Technical Field
[0001] This application relates to the field of refrigerator technology, and in particular to a refrigerator drawer assembly and a refrigerator. Background Technology
[0002] Refrigerator drawers are primarily used for food storage. Drawers located in the refrigerator compartment are usually covered with crisper drawers. These drawers utilize a crisper drawer's internal preservation mechanism and the relatively enclosed space created within the drawer to keep the food fresh. However, this relatively enclosed space can lead to uneven humidity and cold air distribution, causing frost to condense on the drawer walls – a phenomenon known as condensation.
[0003] Currently, the main method for preventing condensation inside refrigerator drawers is to install heating plates or similar structures on the drawer walls. These heating plates prevent the concentration of humidity and cold air around the drawer walls, thus avoiding condensation. However, this method raises the temperature near the heating plate, affecting the overall low-temperature environment inside the drawer and potentially causing food damage. Furthermore, the heating plates and similar structures take up storage space inside the drawer, inconveniencing the user experience. Utility Model Content
[0004] Therefore, it is necessary to provide a refrigerator drawer assembly and refrigerator that has an anti-condensation effect and does not affect the storage space inside the drawer or the low-temperature environment.
[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0006] A refrigerator drawer assembly, the refrigerator drawer assembly comprising:
[0007] The drawer body is enclosed to form a receiving cavity;
[0008] A food preservation partition is disposed above the drawer body in a first direction to cover the drawer body. The food preservation partition is provided with a ventilation cavity, which has an inlet and an outlet. The outlet is connected to the inlet and the receiving cavity, respectively.
[0009] A fan is installed inside the preservation partition. The fan has an air inlet and an air outlet. The air inlet is connected to the accommodating cavity, and the air outlet is connected to the inlet.
[0010] Understandably, this application, by setting up a ventilation cavity and a fan inside the food preservation partition, connects the inlet of the ventilation cavity with the air outlet of the fan. The air inlet of the fan and the inlet and outlet of the ventilation cavity are all connected to the receiving cavity, allowing the air in the receiving cavity to enter the ventilation cavity from the inlet through the fan and then flow out of the ventilation cavity from the outlet back into the receiving cavity. In this way, the high humidity air inside the drawer body can be circulated, avoiding the phenomenon of condensation caused by its accumulation on the periphery of the drawer body. Moreover, this setting does not affect the storage space and low temperature environment inside the drawer body, thus improving the user experience.
[0011] In one embodiment, the ventilation cavity is inwardly enclosed to form a flow ventilation channel, which extends along a second direction;
[0012] The number of outlets is configured to be multiple, and the multiple outlets are respectively connected to the inlet through the flow duct.
[0013] Understandably, the high-humidity air inside the cavity can circulate in the second direction through the airflow duct and flow into the cavity from multiple outlets, forming a circulation, thereby preventing condensation from forming on the walls of the drawer body.
[0014] In one embodiment, the airflow volume of each of the outlets is equal to that of the others.
[0015] Understandably, the airflow from each outlet is equal to that from each other, which ensures uniform airflow through the ventilation duct and prevents excessive airflow from any outlet from causing humid air to accumulate on the walls of the drawer body at the corresponding location, resulting in condensation.
[0016] In one embodiment, the plurality of outlets are arranged sequentially at intervals along the second direction; and the outlet diameter of the plurality of outlets gradually increases along the second direction.
[0017] Understandably, the air outlet diameters of multiple outlets are set to gradually increase along the second direction to ensure that the air volume of each outlet is equal to that of the others, avoiding excessively high air volume at the outlet near the air inlet or excessively low air volume at the outlet far from the air inlet, thereby preventing condensation from forming on the perimeter wall of the drawer body due to uneven air distribution.
[0018] In one embodiment, the airflow duct includes a first air duct and a second air duct that are interconnected, the inlet and part of the outlet are located in the area of the first air duct, and the ventilation area of the first air duct gradually decreases along the second direction;
[0019] The remaining portion of the outlet is located within the area where the second air duct is located, and the ventilation area of the second air duct remains unchanged along the second direction.
[0020] Understandably, the ventilation area of the first air duct gradually decreases along the second direction, which makes the air pressure near the outlet less than that far from the outlet, thus ensuring that the air volume of each outlet is equal and further reducing the phenomenon of condensation on the perimeter wall of the drawer body.
[0021] In one embodiment, the refrigerator drawer assembly further includes an air guide plate, which is disposed corresponding to the outlet and on the air outlet path of the corresponding outlet, for changing the air outlet direction of the air flowing from the corresponding outlet to the accommodating cavity.
[0022] It is understandable that the direction of airflow from the outlet corresponding to the air deflector into the cavity is changed to prevent it from blowing directly onto the periphery of the corresponding outlet inside the drawer body, thereby preventing condensation from forming on the periphery of the drawer body.
[0023] In one embodiment, the air deflector can guide the air passing through the corresponding outlet toward the peripheral wall of the drawer body.
[0024] In one embodiment, the number of air guides is set to multiple, and at least two of the multiple air guides guide the air outward in different directions.
[0025] Understandably, at least two of the multiple air deflectors guide the air outward in different directions. This allows the air at the outlet to flow out in at least two directions, thus circulating the air inside the drawer body through turbulence and preventing condensation.
[0026] In one embodiment, a nitrogen generating module is provided on the preservation partition, and the nitrogen outlet of the nitrogen generating module is connected to the accommodating cavity for supplying nitrogen to the accommodating cavity;
[0027] The ventilation cavity is set up independently of the nitrogen generation module.
[0028] This application also provides the following technical solutions:
[0029] A refrigerator includes the refrigerator drawer assembly of any of the above embodiments.
[0030] Compared with existing technologies, the refrigerator drawer assembly and refrigerator described herein, by setting a ventilation cavity and a fan inside the preservation shelf, connects the inlet of the ventilation cavity with the air outlet of the fan. The air inlet of the fan and the inlet and outlet of the ventilation cavity are all connected to the receiving cavity, so that the air in the receiving cavity can enter the ventilation cavity from the inlet through the fan and then flow out of the ventilation cavity from the outlet back to the receiving cavity. In this way, the high humidity air inside the drawer body can be circulated, avoiding the phenomenon of condensation caused by its accumulation on the periphery of the drawer body. Moreover, this setting does not affect the storage space and low temperature environment inside the drawer body, thus improving the user experience. Attached Figure Description

[0045] Please see Figures 1 to 5As shown, the refrigerator drawer assembly 100 provided in this application includes a drawer body 10, a food preservation partition 20, and a fan 30. The drawer body 10 encloses a receiving cavity 11. The food preservation partition 20 is located above the drawer body 10 in the first direction x and is used to cover the drawer body 10. A ventilation cavity 22 is provided on the food preservation partition 20. The ventilation cavity 22 has an inlet 222 and an outlet 223. The outlet 223 is connected to the inlet 222 and the receiving cavity 11, respectively. The fan 30 is installed inside the food preservation partition 20. The fan 30 has an air inlet 31 and an air outlet 32. The air inlet 31 is connected to the receiving cavity 11, and the air outlet 32 is connected to the inlet 222. Understandably, existing technologies mainly prevent condensation caused by the concentration of high-humidity air on the drawer walls by installing heating plates or other structures inside the drawer. This not only occupies the storage space inside the drawer but also affects the low-temperature environment inside the drawer, making the temperature near the heating plate higher. This affects the low-temperature storage of food, causing food damage and impacting user experience. This application directly sets up a ventilation cavity 22 inside the preservation partition 20, and installs a fan 30 on the preservation partition 20. The inlet 222 on the ventilation cavity 22 is connected to the air outlet 32 of the fan 30. The air inlet 31 of the fan 30 and the inlet 222 and outlet 223 on the ventilation cavity 22 are all connected to the receiving cavity 11. This allows the humid air in the receiving cavity 11 to enter the ventilation cavity 22 through the fan 30 from the inlet 222, and then flow out of the ventilation cavity 22 to the receiving cavity 11 from the outlet 223. In this way, the high humidity air in the drawer body 10 can be circulated, avoiding the phenomenon of condensation caused by it accumulating on the periphery of the drawer body 10. Moreover, this setting method does not affect the storage space and low temperature environment inside the drawer body 10, thus improving the user experience.
[0046] like Figure 2 As shown, the preservation partition 20 is covered by an upper cover plate 21 in the first direction x, and the ventilation cavity 22 and the fan are located inside the preservation partition 20 and are covered by the upper cover plate 21.
[0047] like Figure 3 As shown, the ventilation cavity 22 includes a sealing plate 221 to prevent humid air from entering the interior of the preservation partition 20.
[0048] Please refer to Figure 4 and Figure 5 The ventilation cavity 22 is enclosed inward to form a flow ventilation channel 23, which extends along the second direction y. Multiple outlets 223 are configured, each connected to an inlet 222 via the flow ventilation channel 23. In this way, humidified air within the receiving cavity 11 can circulate along the second direction y through the flow ventilation channel 23 and flow from the multiple outlets 223 into the receiving cavity 11, forming a circulation and preventing condensation from forming on the peripheral walls of the drawer body 10.
[0049] Here, the number of outlets 223 can be set to two, four, five, seven, or eight, and the specific number of outlets 223 can be determined according to the actual situation, without any limitation. In this embodiment, the number of outlets 223 is set to seven.
[0050] In one embodiment, the airflow volume of each outlet 223 is equal to that of the others. This ensures uniform airflow from the airflow duct 23, thereby preventing the concentration of humid air entering the receiving cavity 11 from the airflow duct 23 and causing condensation at the corresponding location within the receiving cavity 11.
[0051] Specifically, multiple outlets 223 are arranged sequentially at intervals along the second direction y; and the outlet diameter of the multiple outlets 223 gradually increases along the second direction y. In this way, the outlet diameter of the outlet 223 farther from the inlet 222 is larger than the outlet diameter of the outlet 223 closer to the inlet 222, thereby avoiding excessively high air volume at the outlet 223 near the inlet 222 or excessively low air volume at the outlet 223 far from the inlet 222, ensuring that the air volume of each outlet 223 is equal to that of the others.
[0052] Furthermore, the airflow duct 23 includes a first air duct 231 and a second air duct 232 that are interconnected. The inlet 222 and part of the outlet 223 are located within the area of the first air duct 231, and the ventilation area of the first air duct 231 gradually decreases along the second direction y. The remaining part of the outlet 223 is located within the area of the second air duct 232, and the ventilation area of the second air duct 232 remains constant along the second direction y. In this way, the air pressure near the outlet 32 of the outlet 223 is less than the air pressure away from the outlet 32, thereby ensuring that the air volume of each outlet 223 is equal to that of each other, further preventing condensation from forming on the periphery of the drawer body 10.
[0053] like Figures 2 to 4 As shown, a nitrogen generating module 24 is installed on the preservation partition 20. The nitrogen outlet of the nitrogen generating module 24 is connected to the accommodating cavity 11 to supply nitrogen to the accommodating cavity 11. The ventilation cavity 22 is set independently of the nitrogen generating module 24. It should be noted that the nitrogen generating module 24 is set to ensure the preservation environment within the accommodating cavity 11 so that the food within the accommodating cavity 11 can be preserved. This structure is a common refrigerator preservation structure and will not be described in detail here.
[0054] Here, the specific location of the ventilation cavity 22 can utilize the extra space inside the preservation partition 20, excluding the nitrogen generation module 24, to avoid occupying the storage space inside the accommodating cavity 11 and reduce the production cost of anti-condensation.
[0055] like Figure 5 and Figure 6As shown, the refrigerator drawer assembly 100 also includes an air guide plate 40, which is correspondingly arranged with the outlet 223 and positioned on the air outlet 223's airflow path to change the airflow direction from the outlet 223 to the receiving cavity 11. It can be understood that changing the airflow direction from the outlet 223 to the receiving cavity 11 by the air guide plate 40 disperses the air into the receiving cavity, preventing it from directly blowing onto the peripheral wall of the outlet 223 inside the drawer body 10, thereby preventing condensation on the peripheral wall of the drawer body 10.
[0056] Furthermore, the air deflector 40 can guide the air passing through the corresponding outlet 223 toward the peripheral wall of the drawer body 10.
[0057] In one embodiment, the number of air guide plates 40 is set to multiple, and at least two of the multiple air guide plates 40 guide the air outward in different directions. In this way, the air that can exit 223 can flow out in at least two directions, and further, through turbulence, the air will not concentrate on the peripheral wall of the drawer body 10, thereby avoiding the phenomenon of condensation on the peripheral wall of the drawer body 10.
[0058] Here, the number of air guide plates 40 can be two, four, or seven, and the specific number of air guide plates 40 can be determined according to the actual situation, without limitation. In this embodiment, the number of air guide plates 40 is seven, corresponding to the number of outlets 223 mentioned above.
[0059] This application also provides a refrigerator, including the refrigerator drawer assembly 100 of any of the above embodiments.
[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
