[0028] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.
[0029] like Figures 1 to 4 As shown, the food preservation device 10 of this embodiment includes a compartment 1 and a drawer 2, with the drawer 2 movably disposed within the compartment 1. The compartment 1 is provided with a first return air grille 11 for airflow entry, and the drawer 2 is provided with a second return air grille 21 for airflow entry. The second return air grille 21 is configured to cooperate with the first return air grille 11. The drawer 2 is used to store food, thereby achieving food preservation.
[0030] like Figures 1 to 3 As shown, compartment 1 has a compartment opening 13, which allows drawer 2 to enter and exit compartment 1. Drawer 2 can be a pull-out drawer, meaning it can be pushed into or pulled out of compartment 1. Drawer 2 has an opening 23 for putting in or taking out food.
[0031] The compartment 1 has a first air inlet on its side wall, and the drawer 2 has a second air inlet on its side wall. When the preservation device 10 is working, the airflow from the refrigeration system flows out from the first air inlet of the compartment 1; then it enters the interior of the drawer 2 through the second air inlet of the drawer 2 to preserve the food inside the drawer 2; then it flows out from the second return air grille 21 of the drawer 2; and finally it flows back to the refrigeration system from the first return air grille 11, forming an airflow circulation.
[0032] The preservation device 10 of this embodiment improves the uniformity of the return airflow inside the compartment 1 by providing a first return air grille 11 on the side wall of the compartment 1 and dispersing the return airflow within the compartment 1. Similarly, a second return air grille 21 is provided on the side wall of the drawer 2 to disperse the return airflow within the drawer 2 and improve its uniformity. Furthermore, by combining the second and first return air grilles, the uniformity of the return airflow in the preservation device 10 is improved, as is the temperature uniformity inside the drawer 2, thereby enhancing the temperature uniformity of the food inside the drawer 2 and improving the preservation effect of the food inside the preservation device 10.
[0033] In some embodiments, the first return air grille 11 is provided with a plurality of first return air holes 111, and the second return air grille 21 is provided with a plurality of second return air holes 211. The second return air holes 211 are different in shape from the first return air holes 111.
[0034] The first return air grille 11 includes a plurality of first ribs, and adjacent two first return air holes 111 are separated by a first rib. The second return air grille 21 includes a plurality of second ribs, and adjacent two second return air holes 211 are separated by a second rib.
[0035] For example, the first return air holes 111 are circular or long-narrow-shaped, and the second return air holes are rectangular.
[0036] By setting the second return air holes 211 to be different in shape from the first return air holes 111, the flow resistance of the airflow inside the drawer 2 can be increased. Thus, the airflow speed inside the drawer 2 is avoided to be too large, so that the airflow and the food inside the drawer 2 can be fully exchanged, and the food preservation effect of the fresh-keeping device 10 is further improved.
[0037] Alternatively, the second return air holes 211 are different in size from the first return air holes 111.
[0038] By setting the second return air holes 211 to be different in size from the first return air holes 111, the flow resistance of the airflow inside the drawer 2 can be increased. Thus, the airflow speed inside the drawer 2 is avoided to be too large, so that the airflow and the food inside the drawer 2 can be fully exchanged, and the food preservation effect of the fresh-keeping device 10 is further improved.
[0039] Alternatively, as shown in Figure 1 , Figure 2 and Figure 4 , the first return air holes 111 are long-strip-shaped holes extending along a first direction, the second return air holes 211 are long-strip-shaped holes extending along a second direction, and the first direction intersects the second direction.
[0040] By setting the first return air holes 111 and the second return air holes 211 to be long-strip-shaped holes, and the extending directions of the first return air holes 111 and the second return air holes 211 are different, the flow resistance of the airflow inside the drawer 2 can be further increased, and the food preservation effect of the fresh-keeping device 10 is further improved.
[0041] Alternatively, the second direction is perpendicular to the first direction, so that the extending directions of the first return air holes 111 and the second return air holes 211 are perpendicular to each other.
[0042] By setting the second direction to be perpendicular to the first direction, the flow resistance of the airflow inside the drawer 2 can be effectively increased, and the food preservation effect of the fresh-keeping device 10 is further improved.
[0043] In order to make the technical solutions of the present disclosure easier to be understood, the following will further describe the technical solutions of the present disclosure by taking the first direction consistent with the up-down direction, the second direction consistent with the left-right direction, and the pushing and pulling direction of the drawer 2 consistent with the front-rear direction as an example. Among them, the up-down direction, the left-right direction and the front-rear direction are as shown in Figures 1 to 4 .
[0044] For example, pulling the drawer 2 forward can pull the drawer 2 out of the chamber 1, and pushing the drawer 2 backward can push the drawer 2 into the chamber 1. The first return air hole 111 extends along the up-down direction, and the second return air hole 211 extends along the left-right direction. Thus, when the airflow flowing out of the second return air hole 211 flows through the first return air hole 111, part of the airflow will be blocked by the ribs of the first return air grille 11, increasing the flow resistance of the airflow, thereby avoiding the airflow in the drawer 2 being too fast, so that the airflow and the food in the drawer 2 can be fully exchanged.
[0045] As shown in Figure 1 and Figure 4 , the first return air grille 11 is arranged on the rear side wall 12 of the chamber 1, and the second return air grille 21 is arranged on the rear side wall 22 of the drawer 2. Among them, the first air inlet can be arranged at the top of the chamber 1, and the second air inlet can be arranged at the top of the drawer 2. The airflow flowing out of the refrigeration system flows into the drawer 2 from top to bottom, and then from the first air inlet of the chamber 1 and the second air inlet of the drawer 2 in sequence, so as to realize the preservation of the food in the drawer 2, and then flows back to the refrigeration system from front to back, and then from the second return air grille 21 and the first return air grille 11 in sequence.
[0046] Optionally, as shown in Figure 2 , Figure 4 , the first return air hole 111 is a rectangular hole or a waist-shaped hole.
[0047] For example, as shown in Figure 2 and Figure 4 , the first return air hole 111 is a rectangular hole.
[0048] By setting the first return air hole 111 as a rectangular hole or a waist-shaped hole, the processing and manufacturing of the first return air grille 11 are facilitated, thereby facilitating the processing and manufacturing of the chamber 1, and being conducive to reducing the cost of the preservation device 10.
[0049] Optionally, as shown in Figure 1 , Figure 5 and Figure 6 , the second return air hole 211 is a rectangular hole or a waist-shaped hole.
[0050] For example, as shown in Figure 1 , the second return air hole 211 is a rectangular hole. As shown in Figure 5 and Figure 6 , the second return air hole 211 is a waist-shaped hole.
[0051] By setting the second return air hole 211 as a rectangular hole or a waist-shaped hole, the processing and manufacturing of the second return air grille 21 are facilitated, thereby facilitating the processing and manufacturing of the drawer 2, and being conducive to reducing the cost of the fresh-keeping device 10.
[0052] Optionally, the size of the first return air hole 111 in the first direction is less than or greater than the size of the second return air hole 211 in the first direction.
[0053] For example, as shown in Figure 1 and Figure 2 , the size of the first return air hole 111 in the up-down direction is L1, and the size of the second return air hole 211 in the up-down direction is L2, L2 is greater than L1.
[0054] By setting the size of the first return air hole 111 in the first direction to be less than or greater than the size of the second return air hole 211 in the first direction, the flow resistance of the airflow inside the drawer 2 can be increased. Thus, the flow rate of the airflow inside the drawer 2 is avoided to be too large, so that the airflow exchanges heat with the food inside the drawer 2 sufficiently, and the food fresh-keeping effect of the fresh-keeping device 10 is further improved.
[0055] Optionally, the size of the first return air hole 111 in the second direction is less than or greater than the size of the second return air hole 211 in the second direction.
[0056] For example, as shown in Figure 1 and Figure 2 , the size of the first return air hole 111 in the left-right direction is L3, and the size of the second return air hole 211 in the left-right direction is L4, L4 is less than L3.
[0057] By setting the size of the first return air hole 111 in the second direction to be less than or greater than the size of the second return air hole 211 in the second direction, the flow resistance of the airflow inside the drawer 2 can be increased. Thus, the flow rate of the airflow inside the drawer 2 is avoided to be too large, so that the airflow exchanges heat with the food inside the drawer 2 sufficiently, and the food fresh-keeping effect of the fresh-keeping device 10 is further improved.
[0058] In other embodiments, as shown in Figure 2 and Figure 4 , the first return air hole 111 is an elongated hole extending in the first direction, as shown in Figure 7 and Figure 8 , the second return air hole 211 is a circular hole, a square hole or a triangular hole.
[0059] For example, the first return air hole 111 is a rectangular hole or a waist-shaped hole, and the second return air hole 211 is a circular hole.
[0060] By setting the first return air hole 111 as an elongated hole extending in the first direction, and setting the second return air hole 211 as a circular hole, a square hole or a triangular hole, the flow resistance of the air flow in the drawer 2 through the second return air hole 211 is large, so as to avoid the air flow in the drawer 2 being too fast, so that the air flow and the food in the drawer 2 can be fully exchanged, and the food preservation effect of the fresh-keeping device 10 is further improved.
[0061] In other embodiments, the second return air hole 211 is an elongated hole extending in the first direction, and the first return air hole 111 is a circular hole, a square hole or a triangular hole.
[0062] For example, the second return air hole 211 is a rectangular hole or a waist-shaped hole, and the first return air hole 111 is a circular hole.
[0063] By setting the second return air hole 211 as an elongated hole extending in the first direction, and setting the first return air hole 111 as a circular hole, a square hole or a triangular hole, the flow resistance of the air flow through the first return air hole 111 is large, so as to avoid the air flow in the drawer 2 being too fast, so that the air flow and the food in the drawer 2 can be fully exchanged, and the food preservation effect of the fresh-keeping device 10 is further improved.
[0064] Optionally, as shown in Figure 2 and Figure 4 , the plurality of first return air holes 111 are arranged in a matrix form.
[0065] For example, as shown in Figure 2 and Figure 4 , the plurality of first return air holes 111 are arranged in a row along the left-right direction.
[0066] By setting the plurality of first return air holes 111 to be arranged in a matrix form, the processing and manufacturing of the first return air grille 11 are facilitated, which is conducive to reducing the cost of the fresh-keeping device 10.
[0067] Optionally, as shown in Figure 1 , Figures 5 to 8 , the plurality of second return air holes 211 are arranged in a matrix form.
[0068] For example, as shown in Figure 1 , Figure 7 and Figure 8 , the plurality of second return air holes 211 are arranged in multiple rows and multiple columns along the left-right direction and the up-down direction. For another example, as shown in Figure 5 and Figure 6 , the plurality of second return air holes 211 are arranged in a row along the left-right direction.
[0069] By setting the plurality of second return air holes 211 to be arranged in a matrix form, the processing and manufacturing of the second return air grille 21 are facilitated, which is conducive to reducing the cost of the fresh-keeping device 10.
[0070] The fresh-keeping device 10 of the embodiment of the present disclosure can avoid the air return wind field of the fresh-keeping device 10 being too concentrated, realize the uniformity of the air return wind field, improve the temperature uniformity inside the drawer 2, improve the temperature uniformity around the food, prolong the fresh-keeping time of the food, improve the user's convenience, save social resources, and the like, by arranging the first air return grille 11 on the side wall of the compartment 1, arranging the second air return grille 21 on the side wall of the drawer 2, and cooperating the second air return grille 21 with the first air return grille 11.
