[0002] Refrigerators are currently the most common refrigeration equipment. A typical small refrigerator on the market has its interior divided into a freezer compartment and a refrigerator compartment, connected by an air duct structure. A fan is connected to the air duct structure, and the evaporator is located in the freezer compartment. The fan is used to transport the cold air around the evaporator to the refrigerator compartment through the air duct structure. To control the flow of cold air in the refrigerator compartment, a simple, effective, and easy-to-operate adjustment mechanism needs to be installed on the air duct structure. Utility Model Content

[0003] The purpose of this utility model is to design a refrigerator structure with a built-in freezer compartment in order to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs a refrigerator structure with a built-in freezer compartment, including a refrigerator body.

The air duct structure has an inner cavity. The inner cavity has a first opening and communicates with the freezer compartment through the first opening. The inner cavity also has a second opening and communicates with the freezer compartment through the second opening. The inner cavity also has a third opening and communicates with the refrigerator compartment through the third opening. The air duct structure also includes an adjustment mechanism slidably connected to the inner cavity. The adjustment mechanism can reciprocate relative to the third opening to adjust the opening size of the third opening, thereby realizing the disconnection and connection between the inner cavity and the refrigerator compartment and the flow control of the connection.

[0005] Preferably, the inner cavity includes a first inner cavity and a second inner cavity that are interconnected. A fan is installed in the first inner cavity, and an evaporator is installed in the second inner cavity. The first opening is located in the first inner cavity, the second opening is located in the second inner cavity, the third opening is located in the first inner cavity, and the adjustment mechanism is installed in the first inner cavity.

[0006] In a further optimization, the adjustment mechanism includes a movable plate slidably connected to the inner wall of the first inner cavity. The movable plate is provided with a baffle that moves together with the movable plate. The inner wall of the first inner cavity is provided with a first stop member. The first stop member has at least three stop portions distributed along the moving direction of the movable plate. The movable plate is provided with a second stop member that moves together with the movable plate. The second stop member is engaged with each stop portion by the movement of the movable plate to form a positioning, thereby causing the baffle to move with the movable plate to block the third opening to different degrees.

[0007] Further optimization involves providing a limiting protrusion on the inner wall of the first inner cavity that extends along the moving direction of the moving plate and limits the top of the moving plate. The limiting protrusion has a limiting protrusion on the side of the moving plate, and the bottom of the moving plate abuts against the bottom of the first inner cavity. The limiting protrusion, the limiting protrusion, and the inner wall of the first inner cavity together form a channel for the moving plate to move back and forth.

[0008] Further optimization involves the first stop component being an integral strip-shaped component with the inner wall of the first inner cavity and arranged along the moving direction of the moving plate. The first stop component has three recesses spaced apart to correspond to the three stop portions respectively. The moving plate has a first groove and a second groove arranged vertically and horizontally. The portion of the moving plate located between the first groove and the second groove forms a second stop component. The first stop component is located within the second groove. The second stop component is also a strip-shaped component, and the second stop component has protrusions that engage with the recesses for positioning.

[0009] Further optimized, the air duct structure includes a cover plate and a back plate, the back plate is placed on the cover plate, the first opening is placed on the back plate, the second opening is placed on the cover plate, the fan is installed on the cover plate, the cover plate and the back plate together form a first inner cavity, the air duct structure is installed inside the refrigerator body, and the inner wall of the refrigerator body and the back plate together form a second inner cavity.

[0010] Further optimization involves a partition within the air duct structure, which, together with a cover plate and a back plate, forms a first inner cavity with a funnel-shaped cross-section. The third opening is located at the bottom of the funnel-shaped first inner cavity, and the fan is located above the third opening. There are two first openings, located on the top two sides of the funnel-shaped first inner cavity, respectively. There are also two second openings, located on the bottom two sides of the funnel-shaped first inner cavity, respectively.

[0011] Further optimization involves providing a sliding groove on the cover plate and a lever on the movable plate, with the lever extending through the sliding groove into the freezer compartment.

[0012] Further optimization involves forming a raised protrusion at the bottom of the first inner cavity along the edge of the first opening, with the top of the raised protrusion forming a horizontal surface that abuts against the baffle.

[0013] Further optimization involves providing a fourth opening at the bottom of the funnel-shaped first inner cavity of the back plate, which communicates with the second inner cavity, and inclined guide plates between the two sides of the fourth opening and the partition.

[0014] The technical advantage of this invention is that an air duct structure is provided between the freezer and refrigerator compartments. The air duct structure includes a first inner cavity and a second inner cavity that are interconnected. The first inner cavity has a first opening and is connected to the freezer compartment through the first opening. The second inner cavity has a second opening and is connected to the freezer compartment through the second opening. The first inner cavity also has a third opening and is connected to the refrigerator compartment through the third opening. Therefore, the first opening, the first inner cavity, the through hole, the second inner cavity, the second opening, and the freezer compartment form a ventilation circulation. An adjustment mechanism is provided in the air duct structure. The adjustment mechanism includes a movable plate that is slidably connected in the first inner cavity. The movable plate moves to block the opening size of the third opening, thereby controlling the flow rate of cold air entering the refrigerator compartment from the first inner cavity, achieving the purpose of controlling the temperature of the refrigerator compartment, and also serving as a switch for the flow rate. The evaporator is located in the second inner cavity. The cold air generated in the second inner cavity first enters the first inner cavity, and then enters the refrigerator compartment through the first inner cavity. This prevents hot air from directly entering the refrigerator compartment and causing temperature fluctuations in the refrigerator compartment when the evaporator is heating and defrosting.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] This utility model includes a refrigerator body 1. Inside the refrigerator body 1, a plate 13 divides the internal space of the refrigerator body 1 into upper and lower layers. The upper layer has a freezer compartment 11, and the lower layer has a refrigerator compartment 12. An air duct structure 2 is provided between the freezer compartment 11 and the refrigerator compartment 12. The air duct structure 2 is located inside the refrigerator body 1 and behind the freezer compartment 11. The air duct structure 2 includes a cover plate 28 and a back plate 29. The cover plate 28 is located at the front, and the back plate 29 covers the cover plate 28. After the back plate 29 and the cover plate 28 are connected, they form an inner cavity with the inner wall of the refrigerator body 1. A partition 210 is provided inside the air duct structure 2. The partition 210 can extend from the inner wall of the back plate 29, or it can extend from the inner wall of the cover plate 28, or it can be a combination of the cover plate 28 and the back plate 29. Simultaneously extending outwards, the partition 210 divides the inner cavity within the air duct structure 2. In this embodiment, the inner cavity is divided into a first inner cavity 21 and a second inner cavity 22. The partition 210, the cover plate 28, and the back plate 29 enclose and form the first inner cavity 21. The first inner cavity 21 has a funnel-shaped cross-section. In this embodiment, the refrigerator body 1 is divided into upper and lower layers by the plate 13. The freezer compartment 11 is on the upper layer, and the air duct structure 2 is located on the upper layer and behind the freezer compartment 11. Therefore, the cover plate 28 and the back plate 29 structure divide the upper space into the freezer compartment 11 and the second inner cavity 22. That is, the second inner cavity 22 is formed by the back plate 29 and the internal space within the refrigerator body 1. Therefore, the air duct structure 2 is composed of the cover plate 28, the back plate 29, the first inner cavity 21, and the second inner cavity 22.

[0019] A fan 5 is installed in the first inner cavity 21, and an evaporator 4 is installed in the second inner cavity 22. A through hole 217 is provided on the back plate 29, so that the first inner cavity 21 and the second inner cavity 22 are connected. The first inner cavity 21 has a first opening 23 and is connected to the freezer compartment 11 through the first opening 23. The second inner cavity 22 has a second opening 24 and is connected to the freezer compartment 11 through the second opening 24. The first inner cavity 21 also has a third opening 25 and is connected to the refrigerator compartment 12 through the third opening 25. Therefore, the first opening 23, the first inner cavity 21, the through hole 217, the second inner cavity 22, the second opening 24 and the freezer compartment 11 form a ventilation circulation.

[0020] The air duct structure 2 also includes an adjustment mechanism that is slidably connected to the first inner cavity 21. The adjustment mechanism can reciprocate relative to the third opening 25 to adjust the opening size of the third opening 25, thereby enabling the first inner cavity 21 to be disconnected, connected, or the flow rate of the cold storage compartment 12 to be controlled.

[0021] The adjustment mechanism includes a movable plate 3 slidably connected to the inner wall of the first inner cavity 21. The movable plate 3 has a baffle 31 that moves together with it. A first stop member 26 is provided on the inner wall of the first inner cavity 21. The first stop member 26 is a strip-shaped member integral with the inner wall of the first inner cavity 21 and arranged along the moving direction of the movable plate 3. The first stop member 26 has at least three stop portions 27 distributed along its length. In this embodiment, there are three stop portions 27, located at both ends and the middle of the first stop member 26. The surface of the strip-shaped member has recesses to form the stop portions 27, with the three recesses corresponding to the three stop portions 27. The movable plate 3 is provided with a second stop member 37 that moves together with the movable plate 3. In this embodiment, the movable plate 3 has a first groove 34 and a second groove 35 that are arranged vertically and horizontally. The portion of the movable plate 3 between the first groove 34 and the second groove 35 forms the second stop member 37. The first stop member 26 is located inside the second groove 35. The second stop member 37 is also a strip-shaped member. The surface of the second stop member 37 is provided with a protrusion 36. The protrusion 36 and the concave portion form a snap-fit ​​positioning. As the movable plate 3 moves, the protrusion 36 of the second stop member 37 can be snapped onto three corresponding stop portions 27 respectively. The three stop portions 27 correspond to the stop plate 3. The degree to which the third opening 25 is blocked is determined by the obstruction of the first position. The third opening 25 is elongated, and the baffle 31 is correspondingly elongated and covers the third opening 25. When in the first position 27, the baffle 31 completely covers the opening of the third opening 25, thereby disconnecting the refrigerator compartment 12 from the first inner cavity 21. When the moving plate 3 is moved, causing the first stop member 26 and the second stop member 37 to disengage from the first stop 27 and move to the second stop 27, the baffle 31 covers half of the third opening 25. At this time, the refrigerator compartment 12 is connected to the first inner cavity 21 and the airflow is halved. When the moving plate 3 is moved, causing the first stop... When the positioning member 26 and the second positioning member 37 are released from the second positioning part 27 and move to the third positioning part 27, the baffle 31 is completely removed from the third opening 25, so that the third opening 25 is fully open. At this time, the flow between the refrigerator compartment 12 and the first inner cavity 21 is at its maximum. Therefore, it can be seen that as the moving plate 3 moves, it drives the baffle 31 to move along the third opening 25. The opening degree of the third opening 25 is controlled by the baffle 31, thereby controlling the flow rate of the third opening 25, thereby controlling the amount of cold air flowing into the refrigerator compartment 12 from the first inner cavity 21, and realizing the control of the cold air in the refrigerator compartment 12.

[0022] Furthermore, the inner wall of the first inner cavity 21 is provided with a limiting protrusion 32 extending along the moving direction of the moving plate 3 and limiting the top of the moving plate 3. The limiting protrusion 32 is provided with a limiting protrusion 33 limiting the side of the moving plate 3. The bottom end of the moving plate 3 abuts against the bottom of the first inner cavity 21. The limiting protrusion 33, the limiting protrusion 32 and the inner wall of the first inner cavity 21 together form a channel for the moving plate 3 to move back and forth, so that the moving plate 3 can move back and forth stably.

[0023] Furthermore, the first inner cavity 21 has a funnel-shaped cross-section, and the third opening 25 is located at the bottom of the funnel-shaped first inner cavity 21, with the fan 5 located above the third opening 25; there are two first openings 23, located on the top two sides of the funnel-shaped first inner cavity 21 respectively; there are also two second openings 24, located on the bottom two sides of the funnel-shaped first inner cavity 21 respectively. This arrangement of the openings facilitates the circulation of cold air between the freezer compartment 11, the first inner cavity 21, and the second inner cavity 22, and also facilitates the flow of cold air from the first inner cavity 21 into the refrigerator compartment 12 below.

[0024] Furthermore, a sliding groove 211 is provided on the cover plate 28, and a lever 38 is provided on the movable plate 3. The lever 38 extends through the sliding groove 211 into the freezer compartment 11. By manually driving the lever 38, the lever 38 moves back and forth along the sliding groove 211, thereby driving the movable plate 3 to move back and forth.

[0025] Furthermore, a raised protrusion 212 is formed at the bottom of the first inner cavity 21 along the edge of the first opening 23, and the top of the raised protrusion 212 forms a horizontal surface 213 that abuts against the baffle 31. This makes it easier for the baffle 31 to block the opening of the first opening 23 and prevents poor contact between the baffle 31 and the first opening 23.

[0026] Furthermore, the back panel 29 is provided with a fourth opening 214 at the bottom of the funnel-shaped first inner cavity 21, which communicates with the second inner cavity 22. The sides of the fourth opening 214 are provided with inclined guide plates 215 between the partition plate 210, so that the cold air in the first inner cavity 21 can enter the fourth opening 214 along the inclined guide plates 215, and then enter the refrigerator compartment 12 through the fourth opening 214, thereby avoiding the accumulation of cold air at the bottom of the first inner cavity 21.

[0027] The second inner cavity 22 has a water tray 216 at the bottom of the evaporator 4. The refrigerator body 1 also has necessary components such as a compressor and a thermostat, which will not be described in detail here.

[0028] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
