Abstract
Description
Technical Field
[0001] This application relates to the field of refrigeration, and in particular to a drawer assembly for a refrigerator and a refrigerator. Background Technology
[0002] The fruit crisper drawer in a refrigerator is a space specifically designed to store and preserve fruit. It uses specific temperature and humidity controls to extend the freshness and flavor of the fruit.
[0003] Currently, the problem with fruit preservation drawers is uneven temperature distribution within the drawer. This uneven temperature distribution is often due to cold air blowing directly into the drawer, which not only affects the overall temperature environment but also leads to insufficient humidity inside the drawer. Insufficient humidity accelerates moisture loss from the fruit, affecting its freshness and taste. Furthermore, when cold air blows directly into the lower-temperature interior of the drawer, condensation is likely to occur, resulting in excessive moisture inside the drawer, which is extremely detrimental to fruit preservation.

[0007] An air guide is installed in the inner liner of the refrigerator. The air guide includes an air outlet, and the moisture-permeable membrane is configured to gradually rise and tilt in the direction of air outlet (301).
[0008] The rear wall is closer to the air guide relative to the front wall.
[0009] Furthermore, the height of the front wall is greater than the height of the rear wall.
[0010] Furthermore, the air guide also includes a return air inlet disposed in the inner liner, the return air inlet being positioned below the bottom surface and away from the second surface of the accommodating space.
[0011] Furthermore, the return air inlet is provided with negative pressure, so that the air outlet returns to the return air inlet after passing through the first surface of the cover plate and the second surface of the bottom plate in sequence.
[0012] Furthermore, the moisture-permeable membrane includes a first side and a second side, the length of the first side being greater than the length of the second side, wherein the first side is perpendicular to the rear wall and the second side is parallel to the rear wall.

[0014] Furthermore, the first line connecting the center of the moisture-permeable membrane and the center of the air vent is not perpendicular to the plane containing the rear wall.
[0015] Furthermore, it also includes a damper and a temperature sensor. The damper is disposed inside the air guide, and the temperature sensor is disposed on the upper surface of the cover plate near the air outlet. Based on the temperature data of the temperature sensor, the damper is controlled to adjust the air volume of the air outlet.
[0016] Furthermore, the positions where the front wall and the rear wall meet the cover plate are designed to be sealed.
[0017] Furthermore, gaps are provided at the positions where the first sidewall and the second sidewall meet the cover plate.

[0040] To provide a further understanding of the purpose, structure, features, and function of this application, the following is provided in conjunction with... Figures 1 to 10 The detailed description of the embodiments is as follows.
[0041] The required temperature for the crisper drawer inside a refrigerator is 0-1℃ and the humidity is around 90%. However, the temperature in the crisper drawer is currently uneven and condensation is prone to occur.
[0042] To address the issue of uneven temperature and condensation within the refrigerator's crisper drawer, this application provides a drawer assembly for a refrigerator, comprising a drawer body 1, a cover 2, and an air guide 3.
[0043] The drawer body 1 includes a receiving space formed by a front wall 11, a rear wall 12 opposite to the front wall 11, a first side wall 13 connecting the front wall 11 and the rear wall 12, a second side wall 14 opposite to the first side wall 13, and a bottom surface 15. The receiving space is used to store food or other items. The rear wall 12 is closer to the air guide 3 relative to the front wall 11. That is, in this application, the rear wall 12 is closer to the inner liner and the air guide 3, and the front wall 11 is set relative to the rear wall 12 and away from the air guide 3.
[0044] A cover plate 2 is disposed at the opening of the accommodating space for closing or opening the drawer. A moisture-permeable membrane 4 is disposed on the first surface of the cover plate 2 away from the accommodating space. The first surface is the upper surface of the outer side of the cover plate 2. The moisture-permeable membrane 4 is a special material, generally made of porous polymer fiber material, which has unique moisture-permeable but air-permeable properties. When the humidity inside the drawer body 1 reaches a certain value, moisture is allowed to pass through. Moisture is extremely fine water mist, such as water mist with a size of 0.0004 micrometers. At the same time, the moisture-permeable membrane 4 can effectively block the entry of external wind, which helps to maintain the humidity requirements inside the drawer body 1.
[0045] An air guide 3 is installed inside the refrigerator liner. The air guide 3 includes an air outlet 301, and the moisture-permeable membrane 4 is located on the air outlet path of the air outlet 301. Specifically, the air guide 3 is positioned inside the refrigerator liner, near the rear wall 12 of the drawer body 1, and the air outlet 301 of the air guide 3 is higher than the height of the rear wall 12 of the drawer body 1. This ensures that the air outlet 301 of the air guide 3 does not directly blow into the interior of the drawer body 1, thus maintaining a high-humidity environment inside the drawer body 1. Furthermore, it should be noted that the plane of the moisture-permeable membrane 4 is not parallel to the air outlet path of the air outlet 301; the moisture-permeable membrane 4 is positioned along... As the air outlet (301) gradually rises and tilts, the air blown out of the air outlet 301 blows directly to the moisture-permeable membrane 4. Since the air blown out of the air outlet 301 is at a low temperature and has a high risk of condensation, blowing the air out of the air outlet 301 directly to the moisture-permeable membrane 4 allows the moisture in the drawer body 1 to be expelled more quickly through the moisture-permeable membrane 4, avoiding condensation. At the same time, after the air blown out of the air outlet 301 passes through the moisture-permeable membrane 4, it carries away the moisture discharged by the moisture-permeable membrane 4 more quickly. When the humidity in the drawer body 1 is higher than the required humidity, this application can adjust the humidity in the drawer body 1 to the required humidity more quickly.
[0046] To ensure that the moisture-permeable membrane 4 is located in the air outlet path of the air outlet 301, in one embodiment of this application, the height of the front wall 11 of the drawer body 1 is higher than the height of the rear wall 12. The moisture-permeable membrane 4 is configured to gradually rise and tilt in the direction of air outlet. In order to match the air outlet path of the air outlet 301, the moisture-permeable membrane 4 is configured to gradually rise and tilt in the direction of air outlet. This tilted design ensures that the air blown out of the air outlet 301 directly blows onto the moisture-permeable membrane 4. The moisture inside the drawer can be quickly discharged through the moisture-permeable membrane 4, avoiding condensation, thereby more effectively regulating the humidity environment inside the drawer.
[0047] To ensure that the moisture-permeable membrane 4 is located in the air outlet path of the air outlet 301, in another embodiment of this application, the height of the front wall 11 of the drawer body 1 is the same as the height of the rear wall 12, and the height of the cover plate 2 near the front wall 11 is higher than the height of the side of the cover plate 2 near the rear wall 12, so that the moisture-permeable membrane 4 is gradually raised and tilted along the air outlet direction. This ensures that the air blown out of the air outlet 301 directly blows onto the moisture-permeable membrane 4, and the moisture inside the drawer can be quickly discharged through the moisture-permeable membrane 4, avoiding condensation.
[0048] Preferably, the air guide 3 further includes a return air vent 302 disposed in the inner liner, the return air vent 302 being positioned below the second surface of the bottom surface 15 away from the accommodating space. The return air vent 302 is disposed in the inner liner, effectively connecting to the entire air duct system. Since the air outlet 301 of the air guide 3 is positioned higher than the rear wall 12 of the drawer body 1, and the return air vent 302 is positioned below the second surface of the bottom surface 15 of the drawer body 1 away from the accommodating space, the air outlet and return air paths of the air guide 3 form a circulating, surrounding airflow path, ensuring uniform temperature inside the drawer body 1. The air outlet 301 passes through the outer surface of the drawer and finally returns to the return air vent 302, preventing cold air from directly blowing into the drawer and interfering with the humidity environment inside the drawer.
[0049] Specifically, the return air vent 302 is set with negative pressure, causing the air outlet 301 to pass sequentially through the first surface of the cover plate 2 and the second surface of the bottom surface 15 back to the return air vent 302. Under the action of negative pressure, the air outlet 301 is guided to the return air vent 302, forming a complete circulation path. This ensures that the air outlet 301 passes through the outer surface of the drawer body 1, achieving a highly efficient cooling effect. It also prevents cold air from being directly blown into the drawer, thus avoiding interference with the humidity environment inside the drawer body 1. This ensures both the low temperature and temperature uniformity requirements inside the drawer body 1, as well as the humidity requirements inside the drawer body 1.
[0050] In some alternative embodiments, the breathable membrane 4 includes a first side and a second side, the length of the first side being greater than the length of the second side, wherein the first side is perpendicular to the rear wall 12 and the second side is parallel to the rear wall 12.
[0051] The first side is specifically designed to be perpendicular to the rear wall 12, i.e., along the air outlet 301. The second side is designed to be parallel to the rear wall 12, along the air outlet 301. The length of the first side of the moisture-permeable membrane 4 is greater than the length of the second side, which helps the moisture-permeable membrane 4 to receive the air outlet 301 to a greater extent, further reducing the risk of condensation.
[0052] Preferably, the size of the moisture-permeable membrane 4 is set to 203 mm on the first side and 124 mm on the second side. This size exactly covers the low-temperature condensation risk area of the cover plate 2, and the moisture inside the drawer body 1 is discharged through the moisture-permeable membrane 4 to avoid condensation.
[0053] In one embodiment, the first distance between the second side and the rear wall 12 is not less than 30mm. Because the air outlet 301 of the air guide 3 has a low air temperature and a high risk of condensation, especially near the air outlet, it is optimal to position the moisture-permeable membrane 4 near the air outlet 301. However, after installing the moisture-permeable membrane 4 on the cover plate 2, it is necessary to ensure both structural strength requirements and reduce condensation on the cover plate 2. Since the moisture-permeable membrane 4 is designed as a raised and inclined structure along the air outlet 301, it ensures that the air does not blow directly onto the cover plate 2 near the rear wall 12. By setting the first distance between the second side of the moisture-permeable membrane 4 and the rear wall 12 to not less than 30mm, it ensures that the air outlet 301 blows directly onto the moisture-permeable membrane 4, avoiding condensation on the cover plate 2 near the air outlet 301, while ensuring the structural strength requirements of the cover plate 2 after installing the moisture-permeable membrane 4.
[0054] Preferably, the first line connecting the center of the moisture-permeable membrane 4 and the center of the air vent is not perpendicular to the plane containing the rear wall 12.
[0055] The first line connecting the center of the moisture-permeable membrane 4 and the center of the air vent is not perpendicular to the plane of the rear wall 12. That is, the moisture-permeable membrane 4 is not directly located at the center of the air vent 301 on the cover 2, but is offset to a certain extent. This ensures that the moisture-permeable membrane 4 can maximize the reception of cold air blown from the air vent 301. Simultaneously, this helps optimize the humidity regulation function of the moisture-permeable membrane 4, ensuring that the humidity environment inside the drawer body 1 is maintained at a suitable level. In actual operation, the slight offset between the moisture-permeable membrane 4 on the cover 2 and the center of the air vent 301 better guarantees the humidity inside the drawer body 1.
[0056] In a preferred embodiment, the drawer assembly of this application further includes a damper and a temperature sensor. The damper is disposed within the air guide 3 and is used to control the airflow of the air outlet 301. The temperature sensor is disposed on the upper surface of the cover plate 2, near the air outlet 301, and can accurately measure the temperature of the cold air blown out of the air outlet 301, thereby providing real-time temperature data. Based on the temperature data of the temperature sensor, the damper is controlled to adjust the airflow of the air outlet 301.
[0057] Specifically, when the temperature of the temperature sensor is lower than the temperature threshold, the damper is adjusted to increase the airflow of the air outlet 301. Conversely, when the temperature of the temperature sensor is higher than the temperature threshold, the damper is adjusted to decrease the airflow of the air outlet 301. The temperature threshold is the lowest temperature value at which the drawer body 1 needs to be cooled.
[0058] More preferably, based on the temperature data from the temperature sensor, in addition to controlling the damper to adjust the airflow of the air outlet 301, the compressor speed is also controlled to adjust the air temperature of the air outlet 301. Specifically, when the temperature of the temperature sensor is lower than the temperature threshold, the damper is adjusted to increase the airflow of the air outlet 301, while the compressor is controlled to run at high speed, using a large airflow and high air temperature to cool the drawer body 1 separately, so as to quickly lower the temperature inside the drawer body 1 and prevent condensation. Conversely, when the temperature of the temperature sensor is higher than the temperature threshold, the damper is adjusted to decrease the airflow of the air outlet 301, while the compressor is controlled to run at low speed.
[0059] To better implement this application, the temperature sensor described above can be set in other positions of the drawer assembly as needed, and this application does not impose specific limitations.
[0060] Preferably, the positions where the front wall 11 and the rear wall 12 meet the cover plate 2 are sealed. Since the front wall 11 and the rear wall 12 of the drawer body 1 are located in the air circulation path from the air outlet 301 to the air return vent 302, the sealing of the positions where the front wall 11 and the rear wall 12 meet the cover plate 2 ensures that the air from the air outlet 301 only circulates around the outer surface of the drawer body 1 and the cover plate 2 in the circulation path, and does not enter the drawer body 1 from these joint positions, thus ensuring the humidity environment inside the drawer body 1.
[0061] The specific sealing method can be selected from sealing materials, sealing gaskets or sealing strips, and this application does not impose specific restrictions.
[0062] Preferably, a gap is provided at the position where the first sidewall 13 and the second sidewall 14 meet the cover plate 2 to enhance the removal of moisture inside the drawer body 1 and ensure that the humidity inside the drawer body 1 does not exceed 90%.
[0063] The preferred gap width is 1 mm.
[0064] The gap width refers to the distance in the gap perpendicular to the direction of the first sidewall 13 and the second sidewall 14.
[0065] In an optional embodiment of this application, at least two non-parallel air guide plates 300 are provided inside the air outlet 301, see [link / reference]. Figure 9 The air guide plate 300 connects the upper and lower cover plates of the air outlet. The non-parallel air guide plates 300 direct the airflow from the air outlet 301 in different directions. Specifically, the air guide plate 300 on the left directs the airflow from the air outlet 301 to the left, and the air guide plate 300 on the right directs the airflow from the air outlet 301 to the right, thus dispersing the airflow from the air outlet 301 and preventing condensation due to localized overcooling. The number and angle of the air guide plates 300 are determined according to actual needs and are not limited in this application.
[0066] A refrigerator includes the drawer assembly for a refrigerator described above. See also Figure 10 The air guide 3 of the drawer assembly is set on the inner liner and connected to the air duct. It guides the air from the air duct to the outside of the drawer body 1 and the cover plate 2 to form a surrounding air path, which ensures the low temperature and temperature uniformity requirements inside the drawer. At the same time, the air outlet path bypasses the inside of the drawer, which ensures the humidity requirements inside the drawer. A moisture-permeable membrane 4 is set on the cover plate 2 of the drawer body 1 to regulate the humidity inside the drawer. At the same time, the moisture-permeable membrane 4 is set at an angle so that the air from the air outlet 301 of the air guide 3 blows directly to the moisture-permeable membrane 4, which greatly reduces the occurrence of condensation.
[0067] This application relates to a drawer assembly and a refrigerator, including a drawer body 1, a cover 2, and an air guide 3. The drawer body 1 includes an enclosing accommodating space; the cover 2 is disposed at the opening of the accommodating space, and a moisture-permeable membrane 4 is disposed on a first surface of the cover 2 away from the accommodating space; the air guide 3 is disposed in the inner liner of the refrigerator, and the air outlet 301 of the air guide 3 passes through the moisture-permeable membrane 4. By aligning the moisture-permeable membrane 4 directly with the air outlet 301, moisture permeation can be effectively achieved, while avoiding condensation due to low air outlet temperature. The air guide 3 forms a surrounding airflow path outside the drawer body 1 and the cover 2, preventing direct airflow into the drawer body 1, thus ensuring both the low temperature and humidity requirements inside the drawer body 1.
