[0033] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.
[0034] As shown in Figures 1 to 5 , the air guide tray 10 of the embodiment of the present disclosure comprises a tray body 1, and the tray body 1 is provided with a plurality of support protrusions 2, wherein a part of the support protrusions 2 are protrusively arranged towards one side of the thickness direction of the tray body 1, and the other part of the support protrusions 2 are protrusively arranged towards the other side of the thickness direction of the tray body 1. The support protrusions 2 are provided with ventilation holes 21 between the top and the bottom thereof.
[0035] In use, the air guide tray 10 of the embodiment of the present disclosure can place the articles on the tray body 1, support the articles by the support protrusions 2 protrusively arranged towards one side of the thickness direction of the tray body 1, and support the tray body by the support protrusions 2 protrusively arranged towards the other side of the thickness direction of the tray body 1, so as to avoid the articles from being in large-area contact with the refrigerator. By arranging the ventilation holes 21 between the top and the bottom of the support protrusions 2, the airflow can flow between the two sides of the thickness direction of the tray body 1 through the ventilation holes 21, thereby increasing the heat exchange effect of the tray body 1 and the airflow, reducing the temperature difference between the tray body and the airflow, reducing the temperature difference around the articles, increasing the temperature uniformity around the articles, and improving the preservation effect of the articles.
[0036] Optionally, as shown in Figure 2 and Figure 4 , the support protrusions 2 protrusively arranged towards one side of the thickness direction of the tray body 1 are first protrusions 22, the support protrusions 2 protrusively arranged towards the other side of the thickness direction of the tray body 1 are second protrusions 23, and the first protrusions 22 and the second protrusions 23 are alternately arranged.
[0037] For example, the thickness direction of the tray body 1 is consistent with the up-down direction, and the first protrusions 22 are arranged upward, and the second protrusions 23 are arranged downward. Figure 1 、 Figure 2 and Figure 4 The first protrusions 22 are arranged upward, and the second protrusions 23 are arranged downward. In use, the goods are placed on the upper side of the air guide tray 10, and the first protrusions 22 support the goods.
[0038] By alternately arranging the first protrusions 22 and the second protrusions 23, the air flow is more uniform between the two sides of the thickness direction of the tray body 1, thereby further reducing the temperature difference around the goods, increasing the temperature uniformity around the goods, and improving the preservation effect of the goods.
[0039] Optionally, as shown in Figure 2 and Figure 4 , the shape of the first protrusion 22 is the same as that of the second protrusion 23, and the size of the first protrusion 22 is the same as that of the second protrusion 23.
[0040] By setting the shape and size of the first protrusion 22 and the second protrusion 23 to be the same, on the one hand, the air flow is more uniform between the two sides of the thickness direction of the tray body 1, thereby further improving the preservation effect of the goods; on the other hand, it is convenient for the processing and manufacturing of the air guide tray 10, which is conducive to reducing the cost of the air guide tray 10.
[0041] Optionally, a plurality of first protrusions 22 are arranged in multiple rows along a first direction, and adjacent two rows of first protrusions 22 are arranged staggered along a second direction. A plurality of second protrusions 23 are arranged in multiple rows along the first direction, and adjacent two rows of second protrusions 23 are arranged staggered along the second direction.
[0042] For example, the first direction is consistent with the left-right direction, and the second direction is consistent with the front-back direction, wherein the left-right direction and the front-back direction are as shown in Figures 1 to 4 A plurality of first protrusions 22 are arranged in multiple rows along the left-right direction, and adjacent two rows of first protrusions 22 are arranged staggered along the front-back direction. A plurality of second protrusions 23 are arranged in multiple rows along the left-right direction, and adjacent two rows of second protrusions 23 are arranged staggered along the front-back direction.
[0043] By arranging the plurality of first protrusions 22 and the plurality of second protrusions 23 in the above manner, on the one hand, the air flow is more uniform between the two sides of the thickness direction of the tray body 1, thereby further improving the preservation effect of the goods; on the other hand, it is convenient for the processing and manufacturing of the air guide tray 10, which is conducive to reducing the cost of the air guide tray 10.
[0044] Optionally, the support protrusions 2 are arc-shaped.
[0045] By setting the support protrusions 2 to be arc-shaped, the flow resistance on the surface of the support protrusions 2 can be reduced, thereby further improving the preservation effect of the goods.
[0046] Optionally, as shown in Figures 1 to 4 The support protrusion 2 is in the shape of a circular arc, and the radius R1 of the support protrusion 2 is 5mm-25mm.
[0047] It can be understood that, under the condition that the height of the support protrusion 2 is constant, the greater the radius of the support protrusion 2, the flatter the surface of the support protrusion 2, the greater the contact area between the article placed on the tray body 1 and the support protrusion 2, and the greater the temperature difference around the article; the smaller the radius of the support protrusion 2, the steeper the surface of the support protrusion 2, the smaller the contact area between the article placed on the tray body 1 and the support protrusion 2, and the smaller the temperature difference around the article. However, if the radius of the support protrusion 2 is too small, it is difficult to manufacture.
[0048] By setting the radius of the support protrusion 2 to be 5mm-25mm, the manufacturing of the support protrusion 2 is facilitated, and the temperature difference around the article is reduced, thereby ensuring the preservation effect of the article.
[0049] Of course, in other embodiments, the support protrusion 2 can also be in the shape of a rectangle, a rhombus, an ellipse, a triangle, or other shapes.
[0050] Optionally, as shown in Figures 1 to 4 The tray body 1 is in the shape of a wave as a whole.
[0051] By setting the tray body 1 to be in the shape of a wave as a whole, the contact area between the article and the tray body 1 and between the tray body 1 and the refrigerator is reduced, the heat exchange effect of the tray body 1 and the airflow is further increased, and the preservation effect of the article is improved.
[0052] Optionally, as shown in Figure 2 The radius R2 of the ventilation hole 21 is 2.5mm-10mm.
[0053] It can be understood that the size of the radius of the ventilation hole 21 not only affects the flow of the airflow, but also affects the structural strength of the tray body 1. The greater the radius of the ventilation hole 21, the smaller the flow resistance of the airflow, but the worse the structural strength of the tray body 1; the smaller the radius of the ventilation hole 21, the better the structural strength of the tray body 1, but the greater the flow resistance of the airflow.
[0054] By setting the radius of the ventilation hole 21 to be 2.5mm-10mm, the structural strength of the tray body 1 is ensured while the flow resistance of the airflow is reduced.
[0055] Optionally, as shown in Figure 2 The height L1 of the support protrusion 2 is 3mm-10mm.
[0056] It can be understood that the greater the height of the support protrusion 2, the greater the space occupied, and the lower the space utilization rate of the refrigerator interior; the smaller the height of the support protrusion 2, the smaller the space for airflow to flow between the two sides of the thickness direction of the tray body 1, and the poorer the heat exchange effect of the tray body 1 and the airflow.
[0057] By setting the height of the support protrusion 2 to 3mm-10mm, the heat exchange effect of the tray body 1 and the airflow can be ensured while ensuring the space utilization rate of the refrigerator interior, and the preservation effect of the goods can be ensured.
[0058] Optionally, as shown in Figure 2 , the distance L2 from the top of the support protrusion 2 to the center of the ventilation hole 21 is 3mm-8mm.
[0059] It can be understood that the smaller the distance from the top of the support protrusion 2 to the center of the ventilation hole 21, the easier it is for the goods to block the ventilation hole 21, and the less conducive to the flow of airflow; the greater the distance from the top of the support protrusion 2 to the center of the ventilation hole 21, the smaller the distance from the bottom of the support protrusion 2 to the center of the ventilation hole 21, and the easier it is for the refrigerator to block the ventilation hole 21, which is also not conducive to the flow of airflow.
[0060] By setting the distance from the top of the support protrusion 2 to the center of the ventilation hole 21 to 3mm-8mm, the ventilation hole 21 can be effectively ensured to be unobstructed, and the preservation effect of the goods can be improved.
[0061] Optionally, as shown in Figure 1 , Figure 3 , and Figure 4 , the edge of the tray body 1 is provided with an annular retaining edge 3, and the retaining edge 3 is bent towards one side of the thickness direction of the tray body 1.
[0062] For example, the retaining edge 3 is bent upwards.
[0063] By providing the retaining edge 3 on the edge of the tray body 1, the goods can be prevented from falling off the edge of the tray body 1, causing the goods to come into direct contact with the refrigerator and affecting the preservation effect of the goods.
[0064] As shown in Figure 5 and Figure 6 , the drawer assembly 100 of the present disclosure comprises a guide air tray 10 and a drawer 20, the guide air tray 10 being the guide air tray 10 of any of the above embodiments, the guide air tray 10 being arranged inside the drawer 20, and the bottom of the guide air tray 10 being in contact with the bottom wall 201 of the drawer 20.
[0065] Among them, the upper end of the drawer 20 is open to form a taking and placing opening, and the guide air tray 10 is placed inside the drawer 20 through the taking and placing opening.
[0066] By arranging the air guide tray 10 in the drawer 20, the preservation effect of the items inside the drawer assembly 100 can be improved.
[0067] The refrigerator of the embodiments of the present disclosure comprises the drawer assembly 100 of any of the above embodiments.
[0068] In other embodiments, the air guide tray 10 can also be used in a freezer, and the bottom of the air guide tray 10 is in direct contact with the bottom plate of the freezer.
