Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator drawer and the refrigerator thereof. Background Technology

[0002] A refrigerator drawer is installed inside the refrigerator and typically consists of a main body and a drawer. The main body is connected to the refrigerator, while the drawer can be pulled out relative to the main body to make it easier for users to access the food stored inside.

[0003] However, because the internal temperature of a refrigerator drawer is low, condensation can easily occur when the internal air temperature is uneven, such as when hot and humid air from outside enters the drawer. Some refrigerator drawers currently have a draft barrier at the opening, but this only blocks outside air when the drawer is closed. When the drawer is pulled out, hot and humid air from outside can still enter. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a refrigerator drawer.

[0005] A refrigerator drawer includes: a body, which is hollow and has a first side with an opening and a second side facing away from the opening; a drawer disposed in the body and movable along the direction of the opening, the drawer having a accommodating cavity for storing food; wherein, an air duct is formed in the side wall of the body, an air inlet is formed on the second side, a first air outlet is formed on the first side, and a second air outlet is formed on the inner wall of the body facing the accommodating cavity, the flow area of ​​the first air outlet is larger than the flow area of ​​the second air outlet, and a damper is installed at the first air outlet, the damper being able to open or close in response to changes in the position of the drawer.

[0006] With this design, cool air enters through the air inlet and, after passing through the air duct, flows in two directions: one exits through the first air outlet, and the other through the second air outlet. When the drawer is not pulled out and is inside the main unit, the damper is closed. In this case, cool air cannot escape from the first air outlet and can only flow into the interior of the drawer through the second air outlet, thus ensuring the cooling capacity of the interior cavity. When the drawer is pulled out, the damper opens. Because the flow area of ​​the first air outlet is larger than that of the second air outlet, more cool air naturally flows towards the first air outlet when it is fully open. Furthermore, the first air outlet is located on the first side, and the drawer is pulled out from the opening on the first side. This means that the first air outlet faces the direction the drawer is pulled out, forming an air curtain that extends towards the drawer, thus preventing hot and humid air from entering the interior cavity of the drawer and avoiding condensation.

[0007] In one embodiment, multiple second air outlets are provided, and multiple second air outlets are arranged in an array.

[0008] In one embodiment, the second air outlet is configured as a circular hole, and the diameter of the second air outlet is 0.5mm-2mm.

[0009] In one embodiment, the air duct is constructed in the top sidewall of the body, and the first air outlet extends horizontally from one end of the first side to the other end.

[0010] In one embodiment, a position sensor is provided on the inner wall of the body, and the drawer has a first position located inside the body and a second position pulled out of the body. The position sensor is capable of obtaining the position of the drawer and is electrically connected to the damper.

[0011] In one embodiment, the damper is installed inside the air duct and is rotatably connected to the inner wall of the air duct, and can circumferentially abut against the air duct by rotation.

[0012] In one embodiment, the height of the air duct gradually decreases along the direction from the second side to the first side, and the flow area of ​​the air inlet is greater than the flow area of ​​the first air outlet.

[0013] In one embodiment, the drawer includes at least a door that extends upward to form the damper, which abuts against the first side and blocks the first air outlet when the drawer is not pulled out.

[0014] In one embodiment, a sealing gasket is provided on the side of the damper facing the body, the sealing gasket abutting against the first side and surrounding the edge of the first air outlet.

[0015] This utility model also provides a refrigerator, including the refrigerator drawer described above.

[0016] Compared to existing technologies, this invention features a first air outlet located on the side where the drawer is pulled out. This allows cool air to flow out from the first air outlet when the drawer is pulled out, forming an air curtain that prevents humid and hot air from the external environment from entering the drawer's containment cavity, thus avoiding condensation problems.

[0028] This utility model provides a refrigerator drawer 100, which forms a horizontal air curtain by opening a first air outlet 142 on the first side 12 of the main body 10, thereby preventing hot and humid air from entering the accommodating cavity 21 inside the drawer 20 when the drawer 20 is pulled out, so as to achieve the function of preventing condensation.

[0029] Please see Figures 1-4 The refrigerator drawer 100 includes a body 10 and a drawer 20. The body 10 is hollow and has a first side 12 with an opening 11 and a second side 13 facing away from the opening 11. The drawer 20 is disposed in the body 10 and can move along the direction of the opening 11. The drawer 20 has a accommodating cavity 21 for storing food. An air duct 14 is constructed in the side wall of the body 10. An air inlet 141 is opened on the second side 13, and a first air outlet 142 is opened on the first side 12. A second air outlet 143 is opened on the inner wall of the body 10 facing the accommodating cavity 21. The flow area of ​​the first air outlet 142 is larger than that of the second air outlet 143. An air damper 15 is installed at the first air outlet 142. The air damper 15 can open or close in response to changes in the position of the drawer 20.

[0030] Thus, cold air enters through the air inlet 141 and, after passing through the air duct 14, has two flow paths: one flows out through the first air outlet 142, and the other flows out through the second air outlet 143. When the drawer 20 is not pulled out by the user and is housed inside the main body 10, the damper 15 is closed. At this time, the cold air cannot flow out from the first air outlet 142 and can only flow into the housing cavity 21 through the second air outlet 143, thereby ensuring the cooling capacity of the housing cavity 21 inside the drawer 20. When the drawer 20 is pulled out, the damper 15 opens. Since the flow area of ​​the first air outlet 142 is larger than that of the second air outlet 143, when the first air outlet 142 is fully open, more cold air will naturally flow towards the direction of the first air outlet 142. Furthermore, the first air outlet 142 is located on the first side 12, and the drawer 20 is pulled out from the opening 11 on the first side 12. That is to say, the first air outlet 142 faces the direction in which the drawer 20 is pulled out, and its air outlet forms an air curtain. The air curtain extends in the direction in which the drawer 20 is pulled out, thereby blocking the external humid and hot air from entering the receiving cavity 21 inside the drawer 20, thus avoiding the problem of condensation.

[0031] Furthermore, multiple second air outlets 143 are configured and arranged in an array. This ensures that the cold air enters the accommodating cavity 21 more evenly after passing through the second air outlets 143, avoiding the problem of one side of the accommodating cavity 21 being cold while the other side is hot.

[0032] Preferably, in this embodiment, the air duct 14 is constructed in the top side wall, and the second air outlet 143 is opened in the top inner wall of the body 10. It blows cold air from top to bottom, which can make the entry of cold air smoother, and the lower temperature air will sink to the bottom of the receiving cavity 21, thereby completing the supercooling from top to bottom. Along the length and width directions of the top inner wall, the second air outlet 143 is evenly spaced in an array on the top inner wall, arranged from one side in the width direction to the other side, and also arranged from one side in the length direction to the other side.

[0033] Preferably, the second air outlet 143 is a round hole with a diameter of 0.5mm-2mm. This reasonably sets the size of the second air outlet 143, ensuring that it is not too small to make it difficult to ventilate, and also avoiding the situation where the air velocity is too low and the airflow is uneven if the second air outlet 143 is too large.

[0034] Understandably, in other embodiments, the second air outlet 143 may also be configured as a rectangular hole or a triangular hole, etc., and is not limited to the circular hole described above.

[0035] The first air outlet 142 extends horizontally from one end of the first side 12 to the other. This ensures the width of the first air outlet 142, making the air curtain it forms more effective at shielding against hot and humid external air.

[0036] Preferably, along the horizontal direction, the width of the first air outlet 142 is greater than the width of the internal accommodating cavity 21 of the drawer 20, so that the air curtain can completely cover the top opening of the accommodating cavity 21.

[0037] A position sensor 30 is provided on the inner wall of the main body 10. The drawer 20 has a first position inside the main body 10 and a second position outside the main body 10. The position sensor 30 can obtain the position of the drawer 20 and is electrically connected to the damper 15.

[0038] The position sensor 30 determines whether to open the damper 15 by acquiring the position of the drawer 20. When the drawer 20 is in the first position, the damper 15 is closed, and the cold air in the air duct 14 enters the accommodating cavity 21 through the second air outlet 143 to maintain the low temperature inside the drawer 20. When the drawer 20 is pulled out to the second position, the damper 15 is opened, and the cold air flows out at high speed from the first air outlet 142, thereby forming an air curtain to prevent the entry of external hot and humid air.

[0039] In this embodiment, the position sensor 30 is set as an infrared sensor, which has a fast response speed and stable performance.

[0040] Specifically, an infrared sensor is installed on the inner wall of the main body 10 near the second side 13 to achieve a more direct and faster acquisition of the position of the drawer 20.

[0041] Preferably, in this embodiment, when the distance between the drawer 20 and the infrared sensor is less than or equal to 5mm, it is determined that the drawer 20 is fully pushed in and located in the first position.

[0042] The damper 15 is installed inside the air duct 14 and is rotatably connected to the inner wall of the air duct 14, and can abut against the air duct 14 circumferentially by rotation. The air duct 14 is opened or closed by rotation, which is simple in structure and low in cost.

[0043] Preferably, in this embodiment, the rotatable angle of the damper 15 is 0-90°.

[0044] Along the direction from the second side 13 to the first side 12, the height of the air duct 14 gradually decreases, and the flow area of ​​the air inlet 141 is larger than the flow area of ​​the first air outlet 142. The cross-sectional shape of the air duct 14 along the direction from the second side 13 to the first side 12 is trapezoidal, and its height decreases as it approaches the air outlet. When the air intake is greater than the air outlet, a high-speed airflow can naturally be formed at the first air outlet 142, thereby ensuring the strength of the air curtain.

[0045] In addition to opening and closing the damper 15 by rotating it as described above, this utility model also provides another embodiment in which the damper 15 is integrated into the door of the drawer 20, thereby enabling the opening or closing of the first air outlet 142.

[0046] Drawer 20 includes at least a door that extends upward to form a damper 15. When drawer 20 is not pulled out, damper 15 abuts against the first side 12 and blocks the first air outlet 142. Thus, when drawer 20 is not pulled out and is in the first position, damper 15 can naturally close the first air outlet 142. When drawer 20 is pulled out, damper 15 disengages from the first side 12, and the first air outlet 142 is opened, thereby forming an air curtain.

[0047] Furthermore, a sealing gasket is provided on the side of the damper 15 facing the body 10. The sealing gasket abuts against the first side 12 and surrounds the edge of the first air outlet 142. In this way, the sealing gasket can improve the tightness of the abutment between the damper 15 and the first side 12, thereby improving the sealing performance.

[0048] This utility model also provides a refrigerator, including the refrigerator drawer 100 as described above.

[0049] Compared with the prior art, this utility model sets a first air outlet 142 on the side of the drawer 20 that is pulled out, so that when the drawer 20 is pulled out, cold air can flow out from the first air outlet 142 and form an air curtain, thereby preventing hot and humid air from the external environment from entering the receiving cavity 21 in the drawer 20, thus avoiding the problem of condensation.

[0050] 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.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
