Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigerators, and more particularly to a temperature-controlled compartment inside a refrigerator. Background Technology
[0002] Currently, refrigerators typically have air vents in the drawers to deliver cold air into them and keep the items inside fresh. However, because the cold air entering the drawers is not distributed evenly, the temperature distribution inside the drawers is uneven, resulting in poor preservation. For example, locally low temperatures can cause the preserved items to freeze and damage. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defect of uneven temperature distribution in the preservation area of the refrigerator in the prior art, and to provide a temperature control room and a refrigerator including the same.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] A temperature-controlled room has an air intake chamber inside, and the temperature-controlled room has an air inlet communicating with the air intake chamber. The air intake chamber is characterized in that multiple rows of guide baffles are spaced apart along the direction toward the air inlet. At least a portion of the guide baffles along the direction toward the air inlet is directly opposite the air inlet. At least a portion of the portion of any row of guide baffles directly opposite the air inlet is not blocked by the guide baffles of other rows along the direction toward the air inlet.
[0006] In this design, at least a portion of the airflow deflectors faces the air inlet. Airflow hitting the deflectors is blocked and then propagates laterally along them, resulting in more uniform airflow within the intake chamber. By ensuring that at least a portion of each row of deflectors facing the air inlet is not obstructed by other deflectors, it avoids the deflectors near the air inlet from blocking the airflow, preventing insufficient downstream airflow. This allows the air entering the intake chamber from the air inlet to be stratified by the deflectors, entering different areas and resulting in a more uniform distribution of air within the intake chamber, thus improving the temperature uniformity within the intake chamber.

[0014] Preferably, the direction of the air outlet toward the receiving cavity is not parallel to the height direction of the air inlet cavity, and is inclined away from the exhaust outlet.
[0015] Preferably, the storage box is provided with support portions on both sides along the height direction and extension direction perpendicular to the air intake cavity, and the cover extends beyond the storage box and is supported on the support portions along both sides along the height direction and extension direction perpendicular to the air intake cavity.
[0016] Preferably, one row of the air guide baffles corresponds to one or more rows of the air outlets. The air guide baffles are movably disposed in the air inlet cavity to open and cover the corresponding air outlets. The air guide baffles are configured such that when any row of the air guide baffles opens the corresponding air outlet, at least a portion of the portion of that row of air guide baffles facing the air inlet is not blocked by the air guide baffles of other rows along the direction toward the air inlet.
[0017] Preferably, the deflector is located on the side opposite to the air inlet along the extension direction of the air inlet chamber and close to the corresponding air outlet, so as to guide the airflow from the air inlet to the corresponding air outlet.
[0018] Preferably, one row of the air guide baffles corresponds to one row of the air outlets.
[0019] Preferably, the air guide baffle is rotatably disposed within the air intake cavity perpendicular to the height direction and extension direction of the air intake cavity to open and close the corresponding air outlet.
[0020] Preferably, the control chamber further includes a drive unit, which is correspondingly arranged with the guide baffle to drive the corresponding guide baffle, and is arranged on the side of the guide baffle perpendicular to the height direction and extension direction of the air inlet chamber.

[0030] At least a portion of the airflow deflectors is positioned directly opposite the air inlet. When airflow hits the deflectors, it is blocked and propagates laterally along the deflectors, resulting in more uniform airflow within the intake chamber. By ensuring that at least a portion of each row of deflectors facing the air inlet is not obstructed by other deflectors, it prevents deflectors near the air inlet from blocking airflow and causing insufficient downstream airflow. This allows the air entering the intake chamber from the air inlet to be stratified by the deflectors, entering different areas and resulting in a more uniform distribution of air within the intake chamber, thus improving temperature uniformity.

[0056] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0057] This embodiment provides a refrigerator. Figures 1-9 This is a schematic diagram of this embodiment.
[0058] like Figure 1 The refrigerator 1000 is equipped with a refrigeration unit and a temperature-controlled compartment 100, such as Figure 2 , Figure 3The temperature control compartment 100 has an air inlet 11 and an air intake chamber 12. The refrigeration unit generates cold air, which sequentially passes through the cold air outlet of the refrigeration unit, the airflow channel in the rear air duct 200, and the air inlet 11 before entering the air intake chamber 12 to provide cold air for the temperature control compartment 100. Regarding the structure of the refrigeration unit within the refrigerator 1000 and how the refrigeration unit and the rear air duct 200 are connected, reference can be made to existing technologies. The length, width, and height directions of the refrigerator 1000 and the temperature control compartment 100 are consistent, corresponding to the W, L, and H directions, respectively. In this embodiment, the direction facing the air inlet 11 within the air intake chamber 12, the height direction of the air inlet 11, and the width direction of the air inlet 11 are parallel to the L, H, and W directions, respectively.
[0059] like Figure 3 , Figure 5 The controlled-temperature greenhouse 100 also includes n rows of flow guide baffles 61. In this embodiment, n = 4, and the n rows of flow guide baffles 61 are spaced apart along the L direction. For ease of description, the multiple rows of flow guide baffles 61 in this embodiment are named Ai, i = 1, 2, ..., n. Figure 7 The flow guide baffle 61 is at least partially aligned with the air inlet 11 along the L direction. The portion of Ai aligned with the air inlet 11 along the L direction is Si, and at least a portion of Si is S1i. S1i is the portion along the direction towards the air inlet 11 that is not blocked by other flow guide baffles 61, thus arranging multiple rows of flow guide baffles 61 in a stepped manner. Figure 7 In the middle section, A1 is the one closest to the air inlet 11 among all the air guide baffles 61. The part of A1 directly facing the air inlet 11 is S1. S1 is not blocked by any other air guide baffles 61, so all of S1 is S11. The part of A4 directly facing the air inlet 11 is S4. Part of S4 is blocked by A1, A2, and A3. The part not blocked by A1, A2, and A3 is S14.
[0060] At least a portion of the airflow deflector 61 is positioned directly opposite the air inlet 11. When airflow hits the deflector 61, it is blocked and then propagates laterally along the deflector 61, resulting in more uniform airflow within the intake chamber 12. By ensuring that at least a portion of each row of deflectors 61 facing the air inlet 11 is not obstructed by other deflectors 61, it prevents the deflectors 61 near the air inlet 11 from intercepting the airflow, thus avoiding insufficient downstream airflow. This allows the air entering the intake chamber 12 from the air inlet 11 to be layered by the deflectors 61, allowing it to enter different areas. Consequently, the air entering the intake chamber 12 from the air inlet 11 is more evenly distributed within the intake chamber 12, thereby improving the temperature uniformity within the intake chamber 12. Figure 6 The dashed lines in the diagram illustrate the general situation of the airflow being stratified by the guide baffle 61 within the intake chamber 12.
[0061] like Figure 7As the distance between the multi-row guide baffles 61 and the air inlet 11 decreases along the direction towards the air inlet 11, the height of the guide baffles 61 along the height direction of the air intake cavity 12 also gradually decreases, so that the multi-row guide baffles 61 are arranged in a stepped shape, and the airflow entering the air intake cavity 12 from the air inlet 11 is layered and utilized along the height direction of the air intake cavity 12, so that the air intake distribution in the air intake cavity 12 is uniform.
[0062] In this embodiment, the air intake cavity 12 extends in a straight line, and the extension direction of the air intake cavity 12 and the orientation of the air outlet 13 are both parallel to the width direction L of the control chamber 100. The height direction of the air intake cavity 12 and the height direction of the air inlet 11 are both parallel to the height direction H of the control chamber 100. The width direction of the air intake cavity 12 is parallel to the length direction W of the control chamber 100. Preferably, the extension length of the air intake cavity 12 is less than the width of the air intake cavity 12, thereby ensuring that the aerodynamic force at the air inlet 11 is sufficient to move to one side of the air intake 11 of the air intake cavity 12.
[0063] In other embodiments, the air intake chamber 12 may be curved and extended; for example... Figure 11 In the middle, the air intake cavity 12 is curved and extended in the W' direction and in the H' direction in the height direction. The H' direction changes at different positions in the extension direction of the air intake cavity 12. Figure 11 The outline of the air intake chamber 12 is shown in the dashed line; the direction of the air intake chamber 12 toward the air inlet 11 is also shown in the dashed line, which is also a rough indication of the airflow stratification of the guide baffle 61.
[0064] In a preferred embodiment, such as Figure 3 , Figure 5 The controlled-temperature chamber 100 is also equipped with a receiving cavity 21 and an air outlet 13. The air inlet 11, the air inlet cavity 12, the air outlet 13, and the receiving cavity 21 are connected in sequence to supply air to the receiving cavity 21. Figure 4 Multiple rows of air outlets 13 are arranged along the direction L toward the air inlet 11, with gaps between adjacent rows of air outlets 13. Multiple rows of air outlets 13 are arranged along the width direction W of the air inlet cavity 12, with gaps between adjacent rows of air outlets 13. The air outlets 13 are evenly distributed to ensure uniform temperature within the receiving cavity 21. Figure 9 The diagram illustrates the airflow velocity cloud map inside the air intake chamber 12 in this embodiment; Figure 10 For comparison, a flow velocity cloud diagram is shown inside the intake chamber 12 after the guide baffle 61 of this embodiment is removed. Figure 10 It can be seen that without the guide baffle 61, the airflow circulates along the outlet direction, forming a large vortex. The flow velocity is low in the central region of the vortex, and less airflow enters the outlet 13 from the inlet chamber 12 at the vortex, resulting in uneven airflow distribution. Figure 9It can be seen that the airflow guide baffle 61 can disperse the airflow entering the air intake chamber 12 from the air inlet 11, so that the airflow entering the air intake chamber 12 is evenly distributed, thereby making the airflow entering the receiving chamber 21 evenly distributed.
[0065] The receiving cavity 21 and the air outlet 13 are both located on one side of the air inlet cavity 12 in the height direction H. The guide baffle 61 is also located on one side of the air inlet cavity 12 in the height direction H. Multiple rows of guide baffles 61 separate the multiple air outlets 13. Air entering the air inlet cavity 12 from the air inlet 11 is evenly distributed within the air inlet cavity 12 by the obstruction of the guide baffles 61, and then enters the receiving cavity 21 from the multiple air outlets 13 dispersed by the guide baffles 61. This ensures even airflow into the receiving cavity 21, resulting in uniform temperature and good temperature control. The air inlet 11 and the receiving cavity 21 are connected through the air inlet cavity 12, allowing cold air to enter and be buffered within the air inlet cavity 12. Due to the high density of cold air, even if the refrigerator 1000 stops supplying cold air to the air inlet 11, the buffered cold air in the air inlet cavity 12 will naturally sink into the receiving cavity 21 due to gravity, ensuring the stability of the temperature inside the receiving cavity 21.
[0066] In other embodiments, the receiving cavity 21 and the air outlet 13 may be omitted, and air may be directly delivered into the air intake cavity 12 to control the temperature within the air intake cavity 12, for example... Figure 12 In other embodiments, the deflector 61 can be distributed on both sides of the intake chamber 12 in the height direction, for example... Figure 13 . Figure 13 The dashed lines in the diagram illustrate the general situation of the airflow being stratified by the guide baffle 61 within the intake chamber 12.
[0067] In a preferred embodiment, the receiving cavity 21 has an opening on the side near the air inlet cavity 12. The temperature-controlled chamber 100 is provided with a cover 1, which covers the opening of the receiving cavity 21. The air inlet cavity 12 is formed by the hollow structure of the cover 1. The air outlet 13 is disposed on the wall surface of the cover 1 near the receiving cavity 21, and the air inlet 11 is disposed 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 .
[0068] In a preferred embodiment, the temperature-controlled room 100 is provided with a storage box 2, which is drawer-shaped. A storage cavity 21 is disposed inside the storage box 2, and an opening is provided at the top of the storage box 2 to form the opening of the storage cavity 21. The storage box 2 is pullable relative to the cover 1, and the pulling direction is parallel to the extension direction L of the air inlet cavity 12. Pulling the storage box 2 away from the air inlet 11 allows it to be pulled out from under the cover 1. The configuration of the storage box 2 can refer to the prior art. In other embodiments, the cover 1 can be set to be open on the side facing the storage box 2, and the storage box 2 can be sealed on the side facing the cover 1, with the air outlet 13 disposed 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 through the cover 1 and the storage box 2, for example, they can be formed by surrounding the wall of other structures.
[0069] In a preferred embodiment, such as Figure 5 The cover 1 has a gap at the side away from the air inlet 11 along the air inlet cavity 12 extension direction L 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.
[0070] like Figure 5 , Figure 6 The direction of the air outlet 13 toward the storage cavity 21 is not parallel to the height direction of the air inlet 12, which can prevent the airflow at the air outlet 13 from blowing directly onto the storage cavity 21. Furthermore, the direction X of the air outlet 13 toward the storage cavity 21 is tilted away from the exhaust port 3, which can reduce the loss of airflow after entering the storage cavity 21 and flowing directly out of the exhaust port 3, and also prevent the airflow from blowing directly onto the panel of the storage box 2 on the exhaust port 3 side, causing it to become too cold and condense. Figure 6 The angle between the direction of the air outlet 13 toward the receiving cavity 21 and the height direction of the air inlet cavity 12 is β, preferably set to 0<β<45°.
[0071] In a preferred embodiment, such as Figure 1 , 2 The controlled-temperature chamber 100 also includes a support portion 4 and an installation portion 5. The support portion 4 is arranged on both sides of the storage box 2 along the width direction of the air inlet cavity 12. The cover portion 1 extends beyond the storage box 2 on both sides along the width direction of the air inlet cavity 12, and the portion of the cover portion 1 extending beyond the storage box 2 is supported on the support portion 4 to achieve the supporting positioning of the cover portion 1. Both the storage box 2 and the support portion 4 are positioned above the installation portion 5 to achieve the supporting positioning of the storage box 2 and the support portion 4.
[0072] like Figure 5A row of baffles 61 corresponds to a row of air outlets 13. The baffles 61 are movably disposed within the air inlet chamber 12, and their movement opens and closes the corresponding air outlets 13. In this invention, the portion S1i of the baffle 61 facing the air inlet 11 in the direction towards the air inlet 11 and not covered by other baffles 61 refers to S1i when the baffle 61 opens the corresponding air outlet 13. By covering the air outlets 13 with the baffles 61, all or some of the air outlets 13 can be flexibly opened or closed according to the temperature requirements within the receiving cavity 21, thereby improving the flexibility and uniformity of temperature control within the receiving cavity 21.
[0073] like Figure 5 The flow deflector 61 is located on the side of the corresponding air outlet 13 facing away from the air inlet 11 along the extension direction L of the air inlet cavity 12, and close to the corresponding air outlet 13. When airflow blows from the air inlet 11 onto the flow deflector 61, it is blocked by the flow deflector to guide the airflow to the corresponding air outlet 13. In other embodiments, when it is not necessary for the flow deflector 61 to guide the airflow to the air outlet 13, the flow deflector 61 can be set away from the air outlet 13, for example... Figure 15 .
[0074] In this embodiment, the flow guide 61 is rotatably disposed within the air intake cavity 12 in the width direction W. The flow guide 61 rotates to open or close the corresponding air outlet 13. The movement of the flow guide 61 to open or close the air outlet 13 can be controlled by monitoring temperature changes within the receiving cavity 21, thus solving the problem of lag in temperature control within the receiving cavity 21.
[0075] like Figure 8 The controlled-temperature chamber 100 is equipped with a drive unit 62, which is correspondingly arranged with a guide baffle 61 for driving the guide baffle 61 to move. Specifically, there is a gap between the guide baffle 61 and the surface of the cover 1 along both sides of the width direction W of the air intake chamber 12 to accommodate the drive unit 62. In this embodiment, the drive unit 62 includes a rotary motor, which is disposed on the side of the guide baffle 61 along the width direction W of the air intake 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 connection. The guide baffle 61 is mounted on the rotating shaft 63 to achieve limiting support within the air intake chamber 12. There is also a gap between the top of the guide baffle 61 and the surface of the cover 1 to avoid motion interference.
[0076] The movement of the air deflectors 61 can be achieved as follows: When the user pulls out the storage box 2, the motor controls all the air deflectors 61 to rotate and seal the air outlet 13. At this time, cold air is stored inside the air inlet cavity 12, preventing hot outside air from entering the air inlet cavity 12. When the user closes the storage box 2, the refrigerator 1000 continues to supply cold air to the air inlet 11. The motor controls all the air deflectors 61 to rotate and open the air outlet 13, allowing cold air to enter the storage cavity 21 for rapid cooling. When the refrigerator 1000 is operating normally, the temperature of the storage cavity 21 can be controlled by opening and closing some of the air deflectors 61, thereby controlling the air intake area entering the storage cavity 21.
[0077] In other embodiments, a row of baffles 61 can be provided to open and close one or more rows of air outlets 13. In other embodiments, the air outlets 13 can be opened or closed by moving the baffles 61.
[0078] like Figure 6 The airflow deflector 61 is arc-shaped. When the air outlet 13 is opened, the opening of the airflow deflector 61 faces both the air inlet 11 and the air outlet 13, and the airflow deflector 61 extends unidirectionally along the height direction H of the air intake chamber 12. The opening of the airflow deflector 61 faces the air inlet 11 to facilitate the flow of air to the corresponding air outlet 13; the opening of the airflow deflector 61 facing the air outlet 13 prevents air from flowing back into the air intake chamber 12 from the receiving chamber 21, thereby preventing cross-contamination of odors between different areas within the temperature control chamber 100 or the refrigerator 1000; the arc-shaped structure reduces airflow loss. Figure 5 The angle between the extension direction of the flow guide 61 and the height direction of the air intake cavity 12 is α, which can be set to 90° < α < 180°, and α can be set to decrease monotonically along the height direction H of the air intake cavity 12 to achieve the effect described in this paragraph. In other embodiments, the shape of the flow guide 61 can be flexibly adjusted according to manufacturing processes, flow guidance requirements, etc., for example... Figures 11-13 , Figure 15 In this design, the guide baffle 61 is set to be straight, which makes it easy to process.
[0079] 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.
[0080] like Figure 2 , Figure 3 Multiple air inlets 11 are spaced apart in the width direction of the air inlet chamber 12 to further improve the uniformity of air intake in the air inlet chamber 12.
[0081] In this embodiment, the total area of the air inlet 11 facing the air intake cavity 12 is smaller than the total area of the air outlet 13 facing the air intake cavity 12. This can reduce the resistance of airflow from the air outlet 13 into the receiving cavity 21, reduce the flow velocity, and increase the air outlet coverage area.
[0082] like Figure 6 The dimension of the air intake chamber 12 in the extension direction is L1, and the distance from the center of the air outlet 13 closest to the air inlet 11 to the air inlet 11 is L2. 0.2L1≤L2≤0.5L1 can prevent the air outlet 13 from being too close to the air inlet 11. The high speed of the air inlet 11 can easily generate negative pressure, which will cause back suction at the air outlet 13.
[0083] like Figure 3 The flow guide 61 extends along the W direction and reaches a position close to the inner wall of the cover, making the flow guide 61 sufficiently effective in blocking and dispersing the incoming flow, thereby improving the uniformity of the incoming flow distribution within the air intake chamber 12. In other embodiments, when the flow guide 61 is not used to close the air outlet 13, the flow guide 61 can be positioned along the W direction to reach or near the inner wall of the cover 1.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
