The refrigerator transports the cold air produced by the evaporator from the cooling chamber to storage chambers such as the refrigerating chamber and the freezing chamber through a air supply structure, so as to realize the refrigeration of the storage chambers. In the related art, due to the limitation of the sizes of the components in the refrigerator, the air supply port deviates from the geometric center line of the storage cavity. Further, when the cold air enters the air volume distribution structure, the problem of too large flow resistance will occur, resulting in poor uniformity of the air supply of the air supply structure.

[0033] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0034] Next, refer to the attached Figures 1 to 6 Describe the air volume distribution assembly, heat preservation barrel assembly and refrigerator according to the embodiments of the present utility model.

[0035] As Figures 1 to 3 shown, the air volume distribution assembly of the embodiment of the present utility model includes a first distribution member 1. The first distribution member 1 is provided with an air outlet 11, a main air path 13 and two ventilation areas 12. The first distribution member 1 has a geometric center line P1 extending in a first direction. The axis of the air outlet 11 deviates from the geometric center line P1 by a preset distance in a second direction. The first direction is orthogonal to the second direction. Among them, the main air path 13 communicates with the air outlet 11 and the two ventilation areas 12. The extending direction of the main air path 13 forms an acute angle with the first direction. The two ventilation areas 12 are respectively arranged on both sides of the width direction of the main air path 13.

[0036] It should be noted that the dimensions between the two side edges of the first distribution member 1 along the second direction and the geometric center line P1 are equal.

[0037] For the air volume distribution assembly according to the embodiment of the present utility model, when the axis of the air outlet 11 deviates from the geometric center line P1 of the first distribution member 1 by a preset distance in the second direction, since the extending direction of the main air path 13 forms an acute angle with the first direction, the problem of too large local angle deviation of the main air path 13 causing a large flow resistance can be reduced. In addition, since the two ventilation areas 12 are respectively arranged on both sides of the width direction of the main air path 13, the air flow flowing through the main air path 13 can be dispersed into the two ventilation areas 12, so that the air volume distribution on both sides of the geometric center line P1 of the first distribution member 1 is generally balanced, which is beneficial to improving the uniformity of the air supply of the air volume distribution assembly.

[0038] It can be understood that one end of the main air path 13 of the air volume distribution component in the embodiment of the present utility model is communicated with the air supply port 11, and the other end of the main air path 13 extends obliquely in a direction away from the air supply port 11. In some specific examples, the two ends of the main air path 13 can be respectively located on both sides of the geometric center line P1.

[0039] In the related art, when the axis of the air supply port 11 deviates from the geometric center line P1 of the first distribution member 1 by a preset distance in the second direction, the main air path 13 is usually designed into a multi-segment bent structure to adapt to the deviation position of the air supply port 11. However, in the air volume distribution component of the above solution, due to the too large local angle deviation of the main air path 13, the resistance of the cold air flowing through the main air path 13 is large. On the one hand, the efficiency of the cold air flowing through is reduced. On the other hand, it is easy to cause uneven air volume discharged from the ventilation area 12, reducing the uniform consistency of the temperature in the storage cavity 41.

[0040] However, the air volume distribution component in the embodiment of the present utility model arranges the main air path 13 obliquely to avoid the problem of local bending of the main air path 13, thereby reducing the resistance of the cold air flowing through the main air path 13. And because the two ends of the main air path 13 are respectively offset to both sides of the geometric center line P1 in the second direction, the air volume distribution on both sides of the geometric center line P1 of the first distribution member 1 can be generally balanced, improving the uniformity of the air supply of the air volume distribution component.

[0041] For example, as Figure 3 shown, the first direction can be the front-back direction of the first distribution member 1, and the second direction can be the left-right direction of the first distribution member 1. Another example is that the first direction can be the left-right direction of the first distribution member 1, and the second direction can be the front-back direction of the first distribution member 1. It should be noted that the front-back, left-right directions of the first distribution member 1 are consistent with the front-back, left-right directions of the refrigerator.

[0042] The first distribution member 1 can be a plate-like structure, and the first direction, the second direction and the thickness direction of the first distribution member 1 are orthogonal to each other in pairs.

[0043] In the example of the present application, the first direction is the front-back direction of the first distribution member 1, and the second direction is the left-right direction of the first distribution member 1. Among them, the air supply port 11 is located at the rear side of the first distribution member 1, the rear end of the main air path 13 is communicated with the air supply port 11, and the main air path 13 extends obliquely in the direction from back to front (extends to the left or extends to the right).

[0044] For example, the axis of the air supply port 11 is in the second direction (such as Figure 2Deviate to the right from the geometric center line P1 by a preset distance in the left - right direction (the left - right direction of [description]), at this time, the rear end of the main air duct 13 is located on the right side of the geometric center line P1, and the front end of the main air duct 13 is located on the left side of the geometric center line P1. Thus, the areas of the two ventilation zones 12 can be made approximately equal to avoid the problem of uneven air volume on the left and right sides of the storage cavity 41.

[0045] In other examples, the axis of the air supply port 11 deviates to the left from the geometric center line P1 by a preset distance along the second direction (such as Figure 2 the left - right direction of [description]), at this time, the rear end of the main air duct 13 is located on the left side of the geometric center line P1, and the front end of the main air duct 13 is located on the right side of the geometric center line P1. Thus, the areas of the two ventilation zones 12 can be made approximately equal to avoid the problem of uneven air volume on the left and right sides of the storage cavity 41.

[0046] Optionally, as Figure 2 and Figure 3 shown, each ventilation zone 12 includes a plurality of branch air ducts 123, and the plurality of branch air ducts 123 are connected to the main air duct 13 and are arranged in sequence along the extension direction of the main air duct 13. It can be understood that the main air duct 13 can disperse the cold air into the plurality of branch air ducts 123, and the plurality of branch air ducts 123 can break up the air in the main air duct 13, so that the air flow distributed by the main air duct 13 gradually disperses from the center to the edge. The arrangement of the main air duct 13 and the branch air ducts 123 is generally in a dendritic (fish - bone - like) distribution to improve the uniformity of air volume distribution of the air volume distribution component.

[0047] For example, the extension direction of each branch air duct 123 is orthogonally arranged with the extension direction of the main air duct 13. It can be understood that the extension direction of the branch air duct 123 has a certain angle with the second direction to adapt to the inclined structure of the main air duct 13. The extension direction of the branch air duct 123 is perpendicular to the extension direction of the main air duct 13, thereby reducing the flow resistance when the main air duct 13 enters the branch air duct 123 and reducing the air loss.

[0048] In some embodiments, as Figure 3 shown, the two ventilation zones 12 are stagger - arranged along the extension direction of the main air duct 13. Thus, the cold quantities received on the left and right sides of the front end of the first distribution member 1 can be approximately balanced, which is beneficial to improving the uniformity of cold quantity distribution of the air volume distribution component.

[0049] Optionally, the two ventilation zones 12 are respectively located on both sides of the geometric center line P1, which can avoid the problem of uneven air volume on the left and right sides of the air volume distribution component.

[0050] Specifically, the two ventilation zones 12 are respectively a first ventilation zone 121 and a second ventilation zone 122. The first ventilation zone 121 and the axis of the air supply port 11 are arranged on the same side of the geometric center line P1 along the second direction (such as Figure 3to the right of the geometric center line P1 of the middle), the second ventilation area 122 is arranged on the other side of the geometric center line P1 along the second direction (such as Figure 3 to the left of the geometric center line P1 of the middle), the first ventilation area 121 and the second ventilation area 122 are arranged in a staggered manner in the first direction, and the second ventilation area 122 is farther away from the air supply port 11 than the first ventilation area 121.

[0051] In other words, the branch air path 123 at the front end of the second ventilation area 122 is closer to the front edge of the first distribution member 1 than the branch air path 123 at the front end of the first ventilation area 121.

[0052] Such as Figure 3 As shown, taking the example that "the axes of the first ventilation area 121 and the air supply port 11 are both arranged on the right side of the geometric center line P1". Since the axes of the first ventilation area 121 and the air supply port 11 are both arranged on the right side of the geometric center line P1, the amount of cold received at the position on the left side of the front end of the first distribution member 1 is less than that at the position on the right side of the front end of the first distribution member 1, which is likely to cause the problem of uneven cold distribution in the storage cavity 41. Therefore, in this application, the second ventilation area 122 is farther away from the air supply port 11 than the first ventilation area 121, which can make the cold received on the left and right sides of the front end of the first distribution member 1 generally balanced, and is beneficial to improving the uniformity of cold distribution of the air volume distribution component.

[0053] In some embodiments, such as Figure 3 As shown, along the extension direction of the main air path 13, the extension lengths of the multiple branch air paths 123 in one of the ventilation areas 12 increase in sequence, and the extension lengths of the multiple branch air paths 123 in the other ventilation area 12 decrease in sequence, thereby improving the uniformity of cold distribution of the first distribution member 1 in the four directions of front, back, left and right. It can be understood that in this application, the extension direction of the main air path 13 refers to the direction from the end of the main air path 13 close to the air supply port 11 to the end of the main air path 13 far from the air supply port 11, that is, the extension direction of the main air path 13 is a directional direction.

[0054] Taking the example that "the axes of the first ventilation area 121 and the air supply port 11 are both arranged on the right side of the geometric center line P1". The lengths of the multiple branch air paths 123 on the right side of the geometric center line P1 gradually increase in the direction from the back to the front, and the lengths of the multiple branch air paths 123 on the left side of the geometric center line P1 gradually shorten in the direction from the back to the front to adapt to the structure of the inclined arrangement of the main air path 13 (that is, the structure in which the rear end of the main air path 13 is on the right side of the geometric center line P1 and the front end of the main air path 13 is on the left side of the geometric center line P1), which can improve the uniformity of cold distribution of the first distribution member 1.

[0055] Specifically, such as Figure 3As shown, the ends of the multiple branch air paths 123 in the first ventilation area 121 (the right ends of the branch air paths 123) are all approximately equal in dimension from the right side edge of the first distributor 1. The ends of the multiple branch air paths 123 in the second ventilation area 122 (the left ends of the branch air paths 123) are all approximately equal in dimension from the left side edge of the first distributor 1. This can ensure the uniformity of the cold air distribution on both the left and right sides of the first distributor 1 and reduce the temperature fluctuation in the storage cavity 41.

[0056] Optionally, as Figure 3 shown, the main body section 132 includes a first branch 1321 and a second branch 1322. The first branch 1321 and the second branch 1322 are arranged in parallel and both extend in a direction away from the air supply opening 11. One ventilation area 12 communicates with the first branch 1321, and the other ventilation area 12 communicates with the second branch 1322. Specifically, the multiple branch air paths 123 in the first ventilation area 121 are sequentially connected to the first branch 1321, and the multiple branch air paths 123 in the second ventilation area 122 are sequentially connected to the second branch 1322.

[0057] It can be understood that, as Figure 3 shown, the first branch 1321 and the second branch 1322 are arranged side by side and extend in the same direction. The first branch 1321 and the second branch 1322 are in the same extension direction as the main air path 13. A number of branch air paths 123 are connected to the first branch 1321 and are arranged on one side in the width direction of the main air path 13, and a number of branch air paths 123 are connected to the second branch 1322 and are arranged on the other side in the width direction of the main air path 13, which can make the air flow distributed by the air volume distribution component gradually disperse from the center to the edge. It can be understood that the above arrangement forms of the main air path 13 and the branch air paths 123 are generally in a dendritic (fishbone-shaped) distribution to improve the uniformity of the air volume distribution of the air volume distribution component.

[0058] In some embodiments, as Figure 2 and Figure 4 shown, the air volume distribution component further includes a second distributor 2. The second distributor 2 is provided on one side in the thickness direction of the first distributor 1. A plurality of groups of air outlet openings 21 are provided on the second distributor 2. The plurality of groups of air outlet openings 21 are in one-to-one correspondence with and communicate with the multiple branch air paths 123. Each group of air outlet openings 21 includes a plurality of independently and spaced air outlet holes 211. This can redistribute the air flow flowing through the branch air paths 123 to improve the uniformity of the air outlet from the air outlet openings 21.

[0059] Optionally, the arrangement direction of the plurality of air outlet holes 211 is the same as the extending direction of the branch air path 123. For example, each group of air outlets 21 includes one or more columns of air outlet holes 211. The multiple columns of air outlet holes 211 are arranged at intervals along the width direction of the branch air path 123. Each column of air outlet holes 211 includes multiple air outlet holes 211, and the multiple air outlet holes 211 are arranged at intervals along the extending direction of the branch air path 123, thereby improving the uniformity of the air outlet of the air outlet 21.

[0060] Among them, the air outlet hole 211 is at least one of a circular hole, an oval hole, and a polygonal hole. It can be understood that the air outlet 21 can be any combination of a circular hole, an oval hole, and a polygonal hole. The actual shape of the air outlet hole 211 can be selectively designed according to the structure of the air volume distribution component and its arrangement position, and the present application does not limit this.

[0061] In the example of the present application, as Figure 1 and Figure 2 shown, the first distribution member 1 is a foam board, and the second distribution member 2 is a plastic board. By designing the first distribution member 1 as a foam board, the heat preservation effect of the air volume distribution component can be improved, and it is convenient to process the main air path 13 and the branch air path 123 on its board. By designing the second distribution member 2 as a plastic board, the structural strength of the air volume distribution component can be ensured, and the probability of damage to the air volume distribution component due to collision can be reduced.

[0062] Optionally, as Figure 3 shown, the main air path 13 includes a transition section 131 and a main body section 132. The two ventilation areas 12 are respectively arranged on both sides of the width direction of the main body section 132. The main body section 132 is communicated with the air supply port 11 through the transition section 131. The included angle between the extending direction of the transition section 131 and the first direction is equal to the included angle between the extending direction of the main body section 132 and the first direction. In other words, the inclination degrees of the transition section 131 and the main body section 132 are the same, so as to reduce the problem of too large local angle deviation of the main air path 13 causing a large flow resistance.

[0063] Furthermore, at least one of the transition section 131 and the main body section 132 has a constant pore diameter along its extending direction. For example, the transition section 131 has a constant pore diameter along its extending direction. Or, the main body section 132 has a constant pore diameter along its extending direction.

[0064] In the example of the present application, both the transition section 131 and the main body section 132 have a constant pore diameter along their extending directions, thereby ensuring the uniformity of the air volume distribution in the main air path 13 and reducing the resistance when cold air flows in the main air path 13.

[0065] As Figure 5As shown in the figure, the insulation bucket assembly of another embodiment of the present utility model includes: a bucket body 3, a drawer 4, and an air volume distribution assembly. There is a refrigerating compartment 31 inside the bucket body 3. The drawer 4 is installed in the refrigerating compartment 31. There is a storage cavity 41 inside the drawer 4. The air volume distribution assembly is the air volume distribution assembly of the embodiment of the present utility model. The air volume distribution assembly is provided on one of the bucket body 3 and the drawer 4, and the ventilation area 12 can send air into the storage cavity 41.

[0066] In the insulation bucket assembly of the embodiment of the present utility model, when the axis of the air supply port 11 deviates from the geometric center line P1 of the first distribution member 1 by a preset distance in the second direction, since the extending direction of the main air path 13 forms an acute angle with the first direction, the problem of too large local angle deviation of the main air path 13 causing a large flow resistance can be reduced. In addition, since the two ventilation areas 12 are respectively arranged on both sides of the width direction of the main air path 13, the air flow flowing through the main air path 13 can be dispersed into the two ventilation areas 12, so that the air volume distribution on both sides of the geometric center line P1 of the first distribution member 1 is generally balanced, which is beneficial to improving the uniformity of the air supply of the air volume distribution assembly.

[0067] Optionally, as Figure 5 shown, the air volume distribution assembly is provided on the bucket body 3 and installed on the top wall of the refrigerating compartment 31. The second distribution member 2 is provided on the lower end surface of the first distribution member 1. Each branch air path 123 is communicated with a plurality of air outlet holes 211, so that the cold air can be dispersed into the storage cavity 41.

[0068] A refrigerator of another embodiment of the present utility model includes the insulation bucket assembly of the embodiment of the present utility model. The technical advantages of the refrigerator of the embodiment of the present utility model are the same as those of the insulation bucket assembly of the above embodiment, and will not be elaborated here.
