[0002] Currently, refrigerators typically have air outlets in drawers to deliver cold air into the drawers, keeping items fresh. However, the cold air entering the drawers is poorly distributed, resulting in uneven temperature distribution within the drawers and poor freshness preservation.

[0017] Preferably, the guide baffle is located on a side of the corresponding air outlet away from the air inlet along the extension direction of the air inlet cavity, and close to the corresponding air outlet, so as to guide the airflow from the air inlet to the corresponding air outlet.

[0018] Preferably, a row of the guide baffles corresponds to a row of the air outlets.

[0019] Preferably, the guide baffle is rotatably arranged in the air inlet cavity perpendicular to the height direction and the extension direction of the air inlet cavity to open and cover the corresponding air outlet.

[0057] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0058] This embodiment provides a refrigerator, Figures 1-9 is a schematic diagram of this embodiment.

[0059] like Figure 1 , the refrigerator 1000 is provided with a refrigeration unit and a temperature-controlled chamber 100, such as Figure 2 、 Figure 3The control room 100 has an air inlet 11 and an air inlet cavity 12; the refrigeration unit is used to generate cold air, and the cold air enters the air inlet cavity 12 through the cold air output port of the refrigeration unit, the air flow channel in the rear air duct 200, and the air inlet 11 in sequence, providing cold air for the control room 100. Regarding the structure of the refrigeration unit in the refrigerator 1000 and how the refrigeration unit and the rear air duct 200 are connected, reference can be made to the existing technology. The length direction, width direction, and height direction of the refrigerator 1000 and the control room 100 are consistent, which are the W direction, L direction, and H direction, respectively. In this embodiment, the direction in the air inlet cavity 12 toward the air inlet 11, the height direction of the air inlet 11, and the width direction of the air inlet 11 are parallel to the L direction, H direction, and W direction, respectively.

[0060] like Figure 3 、 Figure 5 The control room 100 further includes n rows of flow guide blocks 61. In this embodiment, n=4. The n rows of flow guide blocks 61 are spaced apart along the L direction. For ease of description, the multiple rows of flow guide blocks 61 in this embodiment are named Ai, where i=1, 2, ..., n. Figure 7 , the guide block 61 at least partially faces the air inlet 11 along the L direction, the portion of Ai facing the air inlet 11 along the L direction is Si, at least part of Si is S1i, S1i is the portion not blocked by other guide blocks 61 along the direction toward the air inlet 11, so that the multiple rows of guide blocks 61 are arranged in a stepped manner. Figure 7 Among them, A1 is the closest to the air inlet 11 among all the air guide blocks 61, the part of A1 facing the air inlet 11 is S1, and all of S1 is not blocked by other air guide blocks 61, and all of S1 is S11; the part of A4 facing the air inlet 11 is S4, and part of S4 is blocked by A1, A2, and A3, and the part not blocked by A1, A2, and A3 is S14.

[0061] At least a portion of the guide baffles 61 is arranged to face the air inlet 11. When the airflow hits the guide baffles 61, it is blocked by the guide baffles 61 and transferred laterally along the guide baffles 61, making the air intake in the air inlet cavity 12 more uniform. By arranging that each row of guide baffles 61 is at least partially not blocked by other guide baffles 61 in the direction toward the air inlet 11, it is possible to avoid the guide baffles 61 near the air inlet 11 intercepting the airflow and causing insufficient downstream airflow. The air entering the air inlet cavity 12 from the air inlet 11 is blocked and guided by the guide baffles 61, forming stratification and entering different areas. As a result, the air entering the air inlet cavity 12 from the air inlet 11 is more evenly distributed in the air inlet cavity 12, thereby improving the temperature uniformity in the air inlet cavity 12. Figure 6 The dotted lines in the figure illustrate the general situation in which the air flow in the air inlet cavity 12 is stratified by the guide baffle 61 .

[0062] like Figure 7As the distance between the multiple rows of guide blocks 61 and the air inlet 11 decreases in the direction toward the air inlet 11, the height of the guide blocks 61 along the height direction of the air inlet cavity 12 also gradually decreases, so that the multiple rows of guide blocks 61 are arranged in a stepped shape, and the airflow entering the air inlet cavity 12 from the air inlet 11 is layered and utilized along the height direction of the air inlet cavity 12, so that the air in the air inlet cavity 12 is evenly distributed.

[0063] In this embodiment, the air inlet cavity 12 extends straight, and the extension direction of the air inlet cavity 12 and the orientation of the air outlet 13 are both parallel to the width direction L of the control room 100. The height direction of the air inlet cavity 12 and the height direction of the air inlet 11 are both parallel to the height direction H of the control room 100. The width direction of the air inlet cavity 12 is parallel to the length direction W of the control room 100. The extension length of the air inlet cavity 12 is preferably set to be smaller than the width of the air inlet cavity 12, so as to ensure that the air force at the air inlet 11 is sufficient to move the air inlet cavity 12 to one side of the air inlet 11.

[0064] In other embodiments, the air inlet cavity 12 may be curved and extended; for example Figure 11 In the figure, the air inlet cavity 12 is bent and extended, the extension direction is W' direction, and the height direction is H' direction. The H' direction changes at different positions of the extension direction of the air inlet cavity 12. Figure 11 The dotted line in the figure indicates the general outline of the air inlet cavity 12; and the dotted line indicates the direction of the air inlet cavity 12 toward the air inlet 11, which is also a general indication of the air flow stratification by the guide baffle 61.

[0065] In a preferred embodiment, if Figure 3 、 Figure 5 The temperature-controlled room 100 is further provided with a receiving chamber 21 and an air outlet 13. The air inlet 11, the air inlet chamber 12, the air outlet 13 and the receiving chamber 21 are sequentially connected to supply air to the receiving chamber 21. Figure 4 The air outlets 13 are arranged in multiple rows along the direction L toward the air inlet 11, with gaps between adjacent rows of air outlets 13. The air outlets 13 are arranged in multiple columns along the width direction W of the air inlet cavity 12, with gaps between adjacent columns of air outlets 13. The air outlets 13 are evenly distributed to maintain a uniform temperature within the storage cavity 21. Figure 9 The cloud diagram of the air flow velocity in the air inlet cavity 12 in this embodiment is shown; Figure 10 For comparison, the following diagram shows the air velocity cloud diagram in the air inlet cavity 12 after the guide baffle 61 of this embodiment is removed. Figure 10 It can be seen that when the guide baffle 61 is not provided, the airflow circulates along the outlet direction to form a large vortex, the flow velocity in the center of the vortex is relatively low, the airflow in the air inlet cavity 12 at the vortex enters the air outlet 13 less, and the airflow distribution is uneven. Figure 9It can be seen that the provision of the guide baffle 61 can disperse the airflow from the air inlet 11 into the air inlet cavity 12 , so that the airflow entering the air inlet cavity 12 is evenly distributed, thereby making the airflow entering the storage cavity 21 evenly distributed.

[0066] The storage chamber 21 and the air outlet 13 are both located on one side of the height direction H of the air inlet chamber 12. The guide baffles 61 are also located on one side of the height direction H within the air inlet chamber 12. Multiple rows of guide baffles 61 separate the multiple air outlets 13. Air entering the air inlet chamber 12 from the air inlet 11 is evenly distributed within the air inlet chamber 12 by the blocking effect of the guide baffles 61. The air then enters the storage chamber 21 through the multiple air outlets 13 separated by the guide baffles 61. This ensures uniform air intake into the storage chamber 21, thereby achieving a uniform temperature within the storage chamber 21 and achieving effective temperature control. The air inlet 11 and the storage chamber 21 are connected through the air inlet chamber 12, allowing cold air to enter the air inlet chamber 12 for buffering. The cold air has a high density. Even if the refrigerator 1000 stops supplying cold air to the air inlet 11, the cold air buffered in the air inlet chamber 12 will naturally settle into the storage chamber 21 through the through-holes due to gravity, ensuring stable temperature within the storage chamber 21.

[0067] In other embodiments, the receiving chamber 21 and the air outlet 13 may not be provided, and the air is directly delivered to the air inlet chamber 12 to control the temperature in the air inlet chamber 12, for example. Figure 12 In other embodiments, the flow guide baffles 61 may be dispersedly arranged on both sides of the height direction of the air inlet cavity 12, for example Figure 13 . Figure 13 The dotted lines in the figure illustrate the general situation in which the air flow in the air inlet cavity 12 is stratified by the guide baffle 61 .

[0068] In a preferred embodiment, the storage chamber 21 is provided with an opening on one side close to the air inlet chamber 12, and the control room 100 is provided with a cover 1, which is provided on the opening of the storage chamber 21. The air inlet chamber 12 is formed by the hollowing of the cover 1, and the air outlet 13 is provided on the wall surface of the cover 1 close to the storage chamber 21, and the air inlet 11 is provided on the wall surface of the cover 1 along the L direction. In this embodiment, the cover 1 is closed and can store air. In other embodiments, the cover 1 may not be closed, for example Figure 14 .

[0069] In a preferred embodiment, the control room 100 is provided with a storage box 2, and the storage box 2 is in the shape of a drawer, and the storage cavity 21 is provided in the storage box 2. An opening is provided on the top of the storage box 2 to form the opening of the storage cavity 21. The storage box 2 can be pulled out relative to the cover 1, and the pulling direction is parallel to the extension direction L of the air inlet cavity 12. The storage box 2 can be pulled out from under the cover 1 by pulling it away from the air inlet 11. The arrangement of the storage box 2 can refer to the existing technology. In other embodiments, the cover 1 can be provided to be open on one side of the storage box 2, and the storage box 2 can be sealed on the side of the storage box 2 facing the cover 1, and the air outlet 13 can be provided on the storage box 2. In other embodiments, the air inlet 11, the air inlet cavity 12, and the storage cavity 21 may not be formed by the cover 1 and the storage box 2. For example, they may be formed by surrounding the wall of other structures.

[0070] In a preferred embodiment, if Figure 5 The cover 1 has a gap between the side of the cover 1 away from the air inlet 11 along the extension direction L of the air inlet cavity 12 and the top of the storage box 2 to form an exhaust port 3 for exhausting the storage cavity 21. In other embodiments, the position of the exhaust port 3 can be flexibly adjusted according to the air intake situation in the storage box 2.

[0071] like Figure 5 、 Figure 6 The direction of the air outlet 13 toward the storage chamber 21 is not parallel to the height direction of the air inlet chamber 12, which can prevent the airflow at the air outlet 13 from blowing directly into the storage chamber 21. In addition, the direction X of the air outlet 13 toward the storage chamber 21 is tilted away from the exhaust port 3, which can reduce the loss of airflow that flows directly out of the exhaust port 3 after entering the storage chamber 21, and can also prevent the airflow from blowing directly onto the panel of the storage box 2 on the exhaust port 3 side, causing overcooling and condensation. Figure 6 The angle between the direction of the air outlet 13 toward the storage cavity 21 and the height direction of the air inlet cavity 12 is β, and is preferably set to 0<β<45°.

[0072] In a preferred embodiment, if Figure 1 、 2 The controlled temperature chamber 100 is further provided with a support portion 4 and a mounting portion 5. The support portions 4 are arranged on both sides of the storage box 2 along the width direction of the air inlet cavity 12. The cover 1 extends beyond the storage box 2 on both sides along the width direction of the air inlet cavity 12. The portion of the cover 1 extending beyond the storage box 2 is supported on the support portions 4 to achieve support and positioning of the cover 1. The storage box 2 and the support portion 4 are both arranged above the mounting portion 5 to achieve support and positioning of the storage box 2 and the support portion 4.

[0073] like Figure 5, a row of guide baffles 61 corresponds to an exhaust air outlet 13, and the guide baffles 61 are movably arranged in the air inlet cavity 12, and the corresponding air outlet 13 is opened and covered by the movement of the guide baffles 61. In the present invention, the portion S1i of the guide baffle 61 facing the air inlet 11 in the direction toward the air inlet 11 and not covered by other guide baffles 61 refers to S1i when the guide baffle 61 opens the corresponding air outlet 13. By covering the air outlet 13 with the guide baffles 61, all or part of the air outlets 13 can be flexibly opened or closed according to the temperature requirements in the storage cavity 21, thereby improving the flexibility and uniformity of temperature control in the storage cavity 21.

[0074] like Figure 5 The guide block 61 is located on the side of the corresponding air outlet 13 away from the air inlet 11 along the extension direction L of the air inlet cavity 12, and is close to the corresponding air outlet 13. When the airflow from the air inlet 11 blows onto the guide block 61, it will be blocked by the guide block to guide the airflow to the corresponding air outlet 13. In other embodiments, when the guide block 61 is not needed to guide the airflow to the air outlet 13, the guide block 61 can be set away from the air outlet 13, for example Figure 15 .

[0075] In this embodiment, the deflector 61 is rotatably disposed within the air inlet cavity 12 about the width direction W of the air inlet cavity 12. The deflector 61 rotates to open or close the corresponding air outlet 13. The movement of the deflector 61 can be controlled by monitoring temperature changes within the storage cavity 21 to open or close the air outlet 13, thereby resolving the issue of delayed temperature control within the storage cavity 21.

[0076] like Figure 8 The controlled temperature chamber 100 is provided with a drive unit 62, which is correspondingly disposed to the deflector 61 and is used to drive the deflector 61 to move. Specifically, a gap is provided between the two sides of the deflector 61 along the width direction W of the air inlet chamber 12 and the surface of the cover 1 to accommodate the drive unit 62. In this embodiment, the drive unit 62 includes a rotary motor. The drive unit 62 is disposed on the side of the deflector 61 along the width direction W of the air inlet chamber 12. The output end of the rotary motor is provided with an internal spline that cooperates with the external spline of the rotating shaft 63 to achieve a connection. The deflector 61 is mounted on the rotating shaft 63 to achieve limited support within the air inlet chamber 12. There is also a gap between the top of the deflector 61 and the surface of the cover 1 to prevent movement interference.

[0077] The movement of the air guide baffles 61 can be achieved as follows: When the user removes the storage box 2, the motor controls all air guide baffles 61 to rotate and seal the air outlet 13. This allows cold air to be stored within the air inlet chamber 12, preventing hot air from entering. When the user closes the storage box 2, the refrigerator 1000 continues to deliver cold air to the air inlet 11. The motor controls all air guide baffles 61 to rotate and open the air outlet 13, allowing cold air to enter the storage chamber 21, achieving rapid cooling. When the refrigerator 1000 is operating normally, the opening and closing of some air guide baffles 61 can control the air intake area of the storage chamber 21, thereby controlling the temperature of the storage chamber 21.

[0078] In other embodiments, a row of guide blocks 61 may be provided to correspondingly open and close one or more rows of air outlets 13. In other embodiments, the air outlets 13 may be opened or closed by setting the guide blocks 61 to be movable.

[0079] like Figure 6 The guide block 61 is in an arc shape. When the guide block 61 opens the air outlet 13, the opening of the guide block 61 faces the air inlet 11 and the air outlet 13, and the guide block 61 extends unidirectionally along the height direction H of the air inlet cavity 12. The opening of the guide block 61 faces the air inlet 11 to facilitate the diversion of air to the corresponding air outlet 13; the opening of the guide block 61 faces the air outlet 13, which can prevent the air in the storage cavity 21 from flowing back into the air inlet cavity 12, thereby preventing the air in the control room 100 or the refrigerator 1000 from mixing with each other; the arc-shaped structure can reduce the flow loss of airflow. Figure 5 The angle between the extension direction of the guide baffle 61 and the height direction of the air inlet cavity 12 is α, which can be set to 90°<α<180°, and α is set to decrease monotonically along the height direction H of the air inlet cavity 12 to achieve the effect described in this paragraph. In other embodiments, the shape of the guide baffle 61 can be flexibly adjusted according to processing and manufacturing, diversion requirements, etc., for example Figure 11-13 、 Figure 15 In the embodiment, the guide baffle 61 is set to be straight, which is convenient for processing.

[0080] like Figure 7 , the height of the air inlet 11 is h. In a preferred embodiment, the height difference between two adjacent rows of guide baffles 61 along the height direction H of the air inlet cavity 12 is greater than h / n.

[0081] like Figure 2 、 Figure 3 A plurality of air inlets 11 are provided at intervals in the width direction of the air inlet cavity 12 to further improve the uniformity of air intake in the air inlet cavity 12 .

[0082] In this embodiment, the total area of the air inlet 11 facing the air inlet cavity 12 is smaller than the total area of the air outlet 13 facing the air inlet cavity 12, which can reduce the resistance of the air flow from the air outlet 13 into the storage cavity 21, reduce the flow rate, and increase the air outlet coverage area.

[0083] like Figure 6 The dimension of the air inlet cavity 12 in the extension direction is L1, and the distance between the center of the air outlet 13 closest to the air inlet 11 and the air inlet 11 is L2, 0.2L1≤L2≤0.5L1, which can prevent the air outlet 13 from being too close to the air inlet 11, and the high speed of the air inlet 11 can easily generate negative pressure, resulting in back suction at the air outlet 13.

[0084] like Figure 3 The flow guide block 61 extends along the W direction and extends to a position close to the inner wall of the cover portion, so that the flow guide block 61 has a sufficient effect of blocking and dispersing the incoming flow, thereby improving the uniformity of the incoming flow distribution in the air inlet cavity 12. In other embodiments, when the flow guide block 61 is not used to close the air outlet 13, the flow guide block 61 can be set to extend along the W direction to the inner wall of the cover portion 1 or a position close to the inner wall of the cover portion 1.
