The same reference numbers will be used throughout the drawings to refer to the same or like parts or portions. It will be appreciated by those skilled in the art that the drawings are not necessarily drawn to scale. In the accompanying drawings:
fig. 1 and 2 are schematic block diagrams of a refrigerating and freezing apparatus according to an embodiment of the present utility model in different orientations, respectively.
Detailed Description
The present utility model provides a refrigerating and freezing device, and fig. 1 and 2 are schematic structural diagrams of the refrigerating and freezing device in different orientations according to one embodiment of the present utility model. Referring to fig. 1 and 2, a refrigerator-freezer 1 may generally include a cabinet 10 and an evaporator 20.
The case 10 defines therein a first storage compartment 11, a second storage compartment 12, and a third storage compartment 13 for storing articles, and an evaporator compartment 14 for accommodating an evaporator 20.
The evaporator 20 is configured to exchange heat with an air stream flowing therethrough to form a cooled air stream.
Further, the refrigerating and freezing apparatus 1 further includes a first air blower 31, a second air blower 32, and a third air blower 33.
The first air blower 31 is used for driving the cooling air flow generated by the evaporator 20 to flow to the first storage compartment 11.
The second air blower 32 is used for driving the cooling air flow generated by the evaporator 20 to flow to the second storage compartment 12.
The third air blower 33 is used for driving the cooling air flow generated by the evaporator 20 to flow to the third storage compartment 13.
That is, the first storage compartment 11, the second storage compartment 12, and the third storage compartment 13 all provide cooling through the evaporator 20.
The refrigerating and freezing device 1 comprises three storage compartments, wherein the three storage compartments are cooled by one evaporator 20, so that the components are fewer, and the system structure is simple. And, the cooling air flow is carried through three independent air supply fans respectively to three storing compartments, and the air supply between each storing compartment is mutually noninterfere, and is mutually noninterfere, consequently, can realize different warm areas respectively in three storing compartments on the basis of single system to satisfy the storage demand of user's multi-temperature area.
In conventional refrigeration and freezing apparatus, the evaporator chamber is usually disposed at the back or bottom, which occupies the space at the back or bottom of the case 10, resulting in a limited depth dimension of the storage compartment, or a higher bottom height of the storage compartment, which at least visually gives a strong negative experience of low volume ratio to the user.
For this, the evaporator chamber 14 of the present utility model is located at the lower portion of the case 10 and extends in the depth direction of the case 10, and the evaporator 20 is vertically disposed in the evaporator chamber 14. That is, the evaporator 20 extends in the vertical and front-rear directions as a whole to make full use of the space of the evaporator chamber 14 in the front-rear direction and the height direction, and occupies a small space in the lateral direction. It will be appreciated that the evaporator 20 may be disposed vertically within the evaporator chamber 14 or may be disposed slightly inclined within the evaporator chamber 14.
The evaporator chamber 14 where the evaporator 20 is positioned is arranged at the lower part of the box body 10 and extends along the depth direction of the box body 10 so as to reduce the space occupied by the evaporator chamber in the transverse direction. The evaporator 20 is vertically disposed in the evaporator chamber 14, and thus, the evaporator 20 occupies neither the rear space of the case 10 nor the bottom space of the case 10, which improves the depth in the front-rear direction of the storage compartment, and the height in the up-down direction of the storage compartment, and improves the product volume ratio as a whole, and can give a user a better visual experience.
In some embodiments, the first storage compartment 11 and the second storage compartment 12 are located at a lower portion of the case 10 at a lateral interval, that is, the first storage compartment 11 and the second storage compartment 12 are both located at a lower portion of the case 10 and are disposed at a lateral interval.
Further, a third storage compartment 13 is formed at an upper portion of the case 10 above the first storage compartment 11 and the second storage compartment 12 to fully utilize an upper space of the case 10.
Further, an evaporator chamber 14 is located between the first storage compartment 11 and the second storage compartment 12.
According to the utility model, the first storage compartment 11 and the second storage compartment 12 are transversely arranged at intervals, and the evaporator chamber 14 is arranged between the first storage compartment 11 and the second storage compartment 12, namely, the first storage compartment 11 and the second storage compartment 13 are transversely adjacent to the evaporator chamber 14, so that the evaporator chamber 14 is relatively close to the first storage compartment 11 and the second storage compartment 13, and the length of an air supply flow path of the first storage compartment 11 and the second storage compartment 12 is shortened as much as possible, and the problems of large occupied space and low cold energy conveying efficiency due to the length of the air supply flow path are avoided.
In addition, the third storage compartment 13 is located at the upper part of the case 10, which corresponds to being adjacent to the evaporator compartment 14 up and down, so that the air supply path and the air return path of the third storage compartment 13 are conveniently arranged, and the layout rationality among the compartments of the refrigerating and freezing device 1 is improved.
In some embodiments, a first air supply port 111 is provided at an upper portion of a side of the first storage compartment 11 adjacent to the evaporator chamber 14, and a first air return port 112 is provided at a lower portion of a side of the first storage compartment 11 adjacent to the evaporator chamber 14. The first air supply port 111 is directly communicated with the upper space of the evaporator chamber 14 so as to directly supply the cooling air flow flowing out of the upper space of the evaporator chamber 14 into the upper part of the first storage compartment 11, thereby facilitating the uniform distribution of the cooling capacity in the first storage compartment 11. The first return air inlet 112 is in direct communication with the lower space of the evaporator chamber 14 so that the return air flow in the first storage compartment 11 returns to the lower space of the evaporator chamber 14 as soon as possible, thereby again passing through the evaporator 20 for heat exchange.
The first air supply opening 111 for conveying cooling air flow to the first storage compartment 11 is directly communicated with the upper space of the evaporator chamber 14, and the first air return opening 112 of the first storage compartment 11 is directly communicated with the lower space of the evaporator chamber 14, namely, for the first storage compartment 11, only the corresponding air supply opening and air return opening are needed, and an air duct structure is not needed, so that the structure of the refrigerating and freezing device 1 and the assembly process of the refrigerating and freezing device 1 are simplified.
In some embodiments, the first air supply port 111 is higher than the top of the evaporator 20, and the first air return port 112 is lower than the bottom of the evaporator 20, so that almost all the air flowing from the upper space of the evaporator chamber 14 to the first air supply port 111 is the cooling air flowing from bottom to top through the evaporator 20 and exchanging heat with the evaporator 20, and almost all the return air flowing from the first storage compartment 11 can flow again to the evaporator 20 for exchanging heat.
Further, the first air blower 31 is adjacent to the first air outlet 111, so as to control the air supply of the first storage compartment 11 more precisely, and avoid influencing the air supply of the second storage compartment 12 and the third storage compartment 13.
In some embodiments. A second air supply port 121 is provided at an upper portion of a side of the second storage compartment 12 adjacent to the evaporator compartment 14, and a second air return port 122 is provided at a lower portion of a side of the second storage compartment 12 adjacent to the evaporator compartment 14. The second air supply port 121 is directly connected to the upper space of the evaporator chamber 14 so as to directly supply the cooling air flowing out of the upper space of the evaporator chamber 14 to the upper portion of the second storage compartment 12, thereby facilitating uniform distribution of the cooling capacity in the second storage compartment 12. The second return air port 122 is in direct communication with the lower space of the evaporator chamber 14 so that the return air flow in the second compartment 12 returns to the lower space of the evaporator chamber 14 as quickly as possible to again pass through the evaporator 20 for heat exchange.
The second air supply opening 121 for conveying cooling air flow to the second storage compartment 12 is directly communicated with the upper space of the evaporator chamber 14, and the first air return opening 122 of the second storage compartment 12 is directly communicated with the lower space of the evaporator chamber 14, that is, for the second storage compartment 12, only the corresponding air supply opening and air return opening are needed, and an air duct structure is not needed, so that the structure of the refrigerating and freezing device 1 and the assembly process of the refrigerating and freezing device 1 are simplified.
In some embodiments, the second air supply port 121 is higher than the top of the evaporator 20, and the second air return port 122 is lower than the bottom of the evaporator 20, so that almost all the air flowing from the upper space of the evaporator chamber 14 to the second air supply port 121 is the cooling air flowing from bottom to top through the evaporator 20 and exchanging heat with the evaporator 20, and almost all the return air flowing from the second storage compartment 12 can flow again to the evaporator 20 for exchanging heat.
Further, the second air blower 32 is adjacent to the second air outlet 121, so as to control the air supply of the second storage compartment 12 more precisely, and avoid influencing the air supply of the first storage compartment 11 and the third storage compartment 13.
Since the third storage compartment 13 is entirely above the evaporator compartment 14 and the cooling air flow is preferably delivered to the upper part of the third storage compartment 13 according to the principle of cold sink, the supply and return air of the third storage compartment 13 need to be by means of an air duct.
For this purpose, in some embodiments, the third air supply port 131 is provided at the upper rear side of the third storage compartment 13, and the third air return port 132 is provided at the lower rear side of the third storage compartment 13. The third air supply port 131 communicates with the upper space of the evaporator chamber 14 through the air supply duct 41 such that the cooling air flow flowing out of the upper space of the evaporator chamber 14 flows toward the upper space of the third inter-reservoir chamber 13 through the air supply duct 41, and the third air return port 132 communicates with the lower space of the evaporator chamber 14 through the air return duct 42 such that the return air flow flowing out of the third air return port 132 returns to the lower space of the evaporator chamber 14 through the air return duct 42 to exchange heat with the evaporator 20.
In some embodiments, the number of the third air outlets 131 is plural, and the plurality of third air outlets 131 are arranged in two rows spaced apart in the lateral direction, that is, the plurality of third air outlets 131 are arranged in two rows, and the two rows of third air outlets 131 are arranged in the lateral direction at intervals. The plurality of third air outlets 131 arranged in this manner can further ensure uniform air supply to the third storage compartment 13. Wherein each row at least comprises one third air supply opening 131, and the number of the third air supply openings 131 in each row can be reasonably selected according to the height of the third storage compartment 13. For example, when the height of the third storage compartment 13 is high, each row may include a plurality of third air inlets 131 spaced up and down; when the height of the third storage compartment 13 is high, each row may include only one third air supply port 131.
Further, the air supply duct 41 includes a main duct 411 extending vertically, and a plurality of branch ducts 412 extending from the main duct 411 to the respective third air supply ports 131, and the third air supply fan 33 is disposed in the main duct 411, so as to drive the cooling air flow in the main duct 411 to flow to the respective branch ducts 412 more uniformly.
In some embodiments, the return air duct 42 is vertically disposed within the foam layer of the cabinet 10 to avoid occupying the space of the storage compartment.
In some embodiments, the first air blower 31, the second air blower 32, and the third air blower 33 may be centrifugal fans, axial flow fans, or appropriately sized cross flow fans. That is, the present utility model is not limited to the types of the first air blower 31, the second air blower 32, and the third air blower 33.
