The front side wall 101 and the rear side wall 102 are disposed opposite to each other and located at the front and rear ends of the bottom wall 105, respectively, and both the front side wall 101 and the rear side wall 102 extend upward. The left and right side walls 103 and 104 are oppositely disposed, and the left and right side walls 103 and 104 are located at the left and right ends of the bottom wall 105, respectively, and extend upward. The bottom wall 105, the front side wall 101, the rear side wall 102, the left side wall 103 and the right side wall 104 together enclose an interior space 106. The inner space 106 has an opening facing upward, and the door 80 is movably covered above the opening.

Here, the first sidewall 504 and the second sidewall 505 are disposed along the width direction of the liner 10, that is, the first sidewall 504 may be the rear sidewall 102 or the front sidewall 101, and correspondingly, the second sidewall 505 may be the front sidewall 101 or the rear sidewall 102. It can be understood that: one of the front and rear side walls 101 and 102 defines a supply air duct 501 having a supply air outlet 502. This enables air to be discharged from the internal space 106, thereby achieving air cooling.
Optionally, the cover plate 20 is located in the inner space 106 and divides the inner space 106 into a refrigeration cavity 30 and a storage cavity 1061, the cover plate 20 configures an air return opening 201 communicated with the refrigeration cavity 30, wherein the refrigeration cavity 30 and the storage cavity 1061 are communicated through the air return opening 201, an air outlet of the refrigeration cavity 30 is communicated with an air inlet of the air supply duct 501, an air supply opening 502 is arranged in the storage cavity 30, so that air flow of the refrigeration cavity 30 flows into the storage cavity 1061 through the air supply duct 501 and the air supply opening 502 for heat exchange to refrigerate, and the air flow after heat exchange flows back into the refrigeration cavity 30 through the air return opening 201. Here, the storage chamber 1061 is used to contain items to be frozen, such as meat, seafood, or tea. The refrigeration cavity 30 is used for generating refrigeration airflow, the refrigeration airflow can flow to the air supply duct 501 from the refrigeration cavity 30, flow into the storage cavity 1061 from the air supply opening 502, exchange heat with objects in the storage cavity 1061, then flow back into the refrigeration cavity 30 for cooling again, and the cooled airflow flows back to the air supply duct 501 for circulation. Thus, the air path circulation of the refrigerator is realized, and the air cooling refrigeration of the refrigerator is realized. Optionally, the distance between the air return opening 201 and the first side wall 504 is greater than the distance between the air return opening 201 and the second side wall 505. In this embodiment, the first side wall 504 is provided with a blowing opening 502, and the return air opening 201 is close to the second side wall 505, so that the airflow flowing out of the blowing opening 502 can flow in the front-back direction to flow back to the return air opening 201. This increases the airflow flow rate in the front-rear direction (width direction) of the refrigerator, increases the airflow flow area, and improves the temperature uniformity in the internal space 106.
Alternatively, the cover plate 20 may have various shapes such as an L-shape, an inclined shape, and the like. The refrigeration cavity 30 may also be a variety of shapes and located in different locations within the interior space 106. For example, the refrigeration cavity 30 may be located at the left end, the middle portion, or the right end of the inner space 106, and in practical applications, the refrigeration cavity 30 and the storage cavity 1061 may be arranged according to the structure of the inner space 106 of the refrigerator.
It will be appreciated that the cover plate 20 is disposed within the interior space of the inner container so as to define a relatively self-contained refrigeration cavity 30, facilitating the positioning of the refrigeration assembly. Alternatively, the refrigeration component may be an evaporator, a fan, or the like.
Optionally, the refrigeration cavity 30 extends along the width direction of the inner container 10, which facilitates the arrangement of the air return opening 201 close to the second side wall 505 and the communication between the refrigeration cavity 30 and the air supply duct 501 of the first side wall 504. Optionally, the cover plate 20 extends along the width direction of the inner container 10, and one end of the cover plate 20 is connected to the first sidewall 504, and the other end of the cover plate 20 is connected to the second sidewall 505, so as to facilitate stable arrangement of the refrigeration cavity 30 and communication with the air supply duct 501.
Optionally, the cooler further comprises an evaporator 40, the evaporator 40 being located within the refrigeration cavity 30 for cooling the airflow within the refrigeration cavity 30. The refrigeration cavity 30, the air supply duct 501 and the storage cavity 1061 together form a circulation air path. The refrigerator further comprises a fan 50, the fan 50 is located in the air supply cavity and/or the refrigeration cavity 30, and the fan 50 is used for driving the airflow to flow in the circulating air path.
Optionally, fan 50 is located within supply air duct 501. Here, the fan 50 is located in the air supply duct 501, that is, the fan 50 is located on the same side as the air supply duct 501, and the airflow flowing out of the fan 50 does not pass through corners and the like in the process of flowing to the air supply duct 501, so that the airflow flowing resistance in the air supply duct 501 is small, the air volume loss is small, the potential energy consumption is small, and the air supply can be more smooth and uniform. And can reduce the requirement to freezer system, reduce cost.
Optionally, the side walls include a side wall body and an air outlet cover plate 503, as shown in fig. 2, when the side walls define the air supply duct 501, the side wall body protrudes towards a direction away from the internal space 106 to form the air supply duct 501, the air outlet cover plate 503 is covered on one side of the air supply duct 501 facing the internal space 106, and the air outlet cover plate 503 forms the air supply outlet 502. Specifically, in the present application, under the condition that the first side wall 504 defines the air supply duct 501, the first side wall 504 includes a first side wall body and an air outlet cover plate 503, and the first side wall body protrudes towards the direction departing from the inner space 106 to form the air supply duct 501. The air outlet cover 503 is disposed on a side of the air duct 501 facing the inner space 106, and the air outlet cover 503 forms an air outlet 502.
In this embodiment, first side wall body forms air supply duct 501 towards the direction protrusion that deviates from inner space 106, that is to say, first side wall body is towards the foaming layer protrusion, and air supply duct 501 can not occupy inner space 106 like this, and then can guarantee the storing space of freezer. Air outlet cover plate 503 is matched with air supply duct 501, so that the air flow in air supply duct 501 can flow along air supply duct 501 and flow out from air supply outlet 502.
Alternatively, the air supply duct 501 extends in the longitudinal direction of the first sidewall 504. Here, the air supply duct 501 extends in the longitudinal direction of the first side wall 504, and thus the air output of the refrigerator in the longitudinal direction can be increased, and the air output and temperature uniformity of the internal space 106 can be improved.
Alternatively, the air supply duct 501 may extend linearly, or may be curved or bent. The form of air supply duct 501 that can increase the air output of freezer length direction all belongs to the optional embodiment of this application.
Optionally, the number of the air supply ducts 501 is one or more, and when there are a plurality of air supply ducts 501, at least two air supply ducts 501 of the plurality of air supply ducts 501 are sequentially arranged at intervals along the height direction of the inner container 10.
In this embodiment, as shown in fig. 2, at least two air supply ducts 501 are arranged at intervals along the height direction of the inner container 10, so that the air output of the refrigerator in the height direction can be increased. Thus, the freezer can have airflow along the length, width and height to further improve the air output and temperature uniformity of the interior 106.
Alternatively, the air duct 501 may be provided at an upper portion of the first sidewall 504, at a middle portion of the first sidewall 504, or at a lower portion of the first sidewall 504. When the number of the air supply ducts 501 is plural, the air supply ducts 501 having different heights may be provided, for example, the air supply ducts 501 are provided on the upper portion and the lower portion of the first side wall 504, or the air supply ducts 501 are provided on the upper portion and the middle portion of the first side wall 504. The air supply duct 501 with different heights can supply air to the internal space 106 with different heights, so that the flexibility of air outlet of the refrigerator and the air outlet quantity are improved.
Alternatively, as shown in fig. 1 and 9, the upper wall surface of the bottom wall 105 and/or the lower wall surface of the door 80 is configured with an air guide channel 60, the air guide channel 60 extends in the width direction of the inner container 10 (i.e., in the front-rear direction), and the air guide channel 60 can cooperate with the air blowing port 502 to make the air flow of the air blowing port 502 flow from the rear to the front or from the front to the rear. Thus, the flow area of the airflow is increased, the uniformity of the air supply is improved, the temperature of the inner space 106 is more uniform, and the refrigerating effect of the refrigerator is improved.
Alternatively, the upper wall surface of the bottom wall 105 is configured with a first air guiding channel 601, the first air guiding channel 601 corresponds to the air blowing opening 502, and the first air guiding channel 601 extends along the width direction of the inner container 10 so that the air flow flowing out of the air blowing opening 502 can flow to the second side wall 505. The air guide passage 60 includes a first air guide passage 601.
In this embodiment, the air supply duct 501 and the air outlet are located on the first sidewall 504, and since articles are placed in the internal space 106, the articles can block the airflow of the air supply outlet 502 from flowing to the second sidewall 505. The first air guiding channel 601 can correspond to the air supply opening 502, specifically, the position of the first air guiding channel 601 corresponds to the air supply opening 502, so that the airflow flowing out of the air supply opening 502 can flow to the second side wall 505 along the first air guiding channel 601, which improves the air supply uniformity, ensures that the airflow can flow from the first side wall 504 to the second side wall 505, and improves the air output and temperature uniformity of the inner space 106.
Alternatively, when the first air guiding channel 601 is formed on the upper wall surface of the bottom wall 105, the air supply duct 501 is located at the lower portion of the first side wall 504, so that the air supply opening 502 and the first air guiding channel 601 can better match air supply and guiding.
Optionally, a second air guiding channel 602 is configured on the lower wall surface of the door 80, the second air guiding channel 602 corresponds to the air supply opening 502, and the second air guiding channel 602 extends along the width direction of the inner container 10, so that the air flow flowing out of the air supply opening 502 can flow to the second side wall 505. The air guide passage 60 includes a second air guide passage 602. Similarly, when door 80 is provided to cover internal space 106, if there are many articles in internal space 106, the articles can block the flow of air flowing out of air outlet 502. The second wind guiding channel 602 can guide the airflow from the wind blowing opening 502 on the top of the first sidewall 504 to the second sidewall 505, thereby improving the wind output and temperature uniformity of the inner space 106.
Optionally, when the lower wall surface of door 80 is configured with second air guiding channel 602, air supply duct 501 is located on the upper portion of first side wall 504, so that air supply outlet 502 and second air guiding channel 602 can better cooperate to supply air and guide flow.
Optionally, the number of the air guide channels 60 is multiple, and the air guide channels 60 are sequentially arranged at intervals along the length direction of the liner 10.
In this embodiment, the plurality of air guide channels 60 can guide the air flow flowing out of the air supply opening 502 in the length direction, increase the air output of the air supply opening 502, and improve the air cooling effect.
