Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to an air duct adjustment structure for an air-cooled refrigeration equipment. Background Technology

[0002] Traditional refrigerators and freezers typically employ a fixed air duct structure, where the positions of components such as the volute, fan, and dampers are fixed. This design limits the dampers to only two states: open and closed. Once the volute design is determined, the airflow to each compartment is also fixed. Because of this lack of flexibility, the airflow to each compartment cannot be dynamically adjusted according to actual needs, resulting in imprecise temperature control and difficulty in meeting users' demands for freely switching between freezing and refrigeration functions in different compartments. This fixed air duct design not only restricts the functional versatility of refrigeration equipment but also negatively impacts the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide an air duct adjustment structure for an air-cooled refrigeration equipment, which can adjust the air volume of the air duct and realize flexible control of the air volume of each compartment of the refrigeration equipment, thereby meeting the user's need to freely switch between freezing and refrigeration functions in different compartments.

[0004] This utility model includes a fan, a rotating cover rotatably mounted on the front side of the fan, the rotating cover including a rotating plate, a vent on the surface of the rotating plate, and a windbreak wall extending rearward from the surface of the rotating plate on the rear side of the rotating plate; a fixed cover fixedly mounted on the rear side of the fan, the fixed cover including a base plate and an annular side plate extending forward from the surface of the base plate; the rotating cover and the fixed cover are coaxially arranged, and the windbreak wall is sleeved on the inner side of the annular side plate, thereby forming a closed windbreak structure around the fan, and an air outlet is opened on the side of the windbreak structure; a large gear is fixedly connected to the front side of the rotating cover, the large gear meshes with a small gear, and the small gear is connected to a motor.

[0005] Preferably, there are two air outlets, which are symmetrically arranged on both sides of the central axis of the fan.

[0006] Preferably, the windbreak wall is divided into two sections by two air outlets, and each section of the windbreak wall has an arc-shaped first air guide plate on its inner side; the first air guide plate starts from a certain point on the inner side of the air outlet and gradually expands towards the outer periphery of the rotating plate, with its end point located on the windbreak wall; the two arc-shaped first air guide plates are arranged in the shape of a double volute curve on the rotating plate.

[0007] Preferably, the starting point of the first air guide plate and the ending point of the windbreak wall are on the same radial line.

[0008] Preferably, a second wind guide plate is connected between the starting point of the windbreak wall and the first wind guide plate, and the second wind guide plate is an arc-shaped plate with its opening facing the air outlet side.

[0009] Preferably, the thickness of the windbreak wall gradually decreases at the end point to form a guide surface.

[0010] Preferably, the outer diameter of the windbreak wall is the same as the outer diameter of the rotating plate.

[0011] Preferably, the outer diameter of the annular side plate is the same as the outer diameter of the base plate of the fixed cover.

[0012] Preferably, the rotating cover, the fixed cover, and the fan are arranged coaxially.

[0013] Preferably, the large gear is an internal gear and the small gear is an external gear, with the small gear meshing inside the large gear.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. The motor drives the small gear to rotate, which in turn drives the large gear to rotate, thereby causing the rotating cover to rotate. As the rotating cover rotates, when the air outlet on one side gradually becomes larger, the air outlet on the other side gradually becomes smaller and blocked. Through this design, the air supply ratio of the two chambers can be flexibly adjusted, thereby achieving dynamic adjustment of the temperature distribution.

[0016] 2. It can dynamically adjust the air volume of each compartment according to actual needs, meet the user's need to freely switch between freezing and refrigeration functions in different compartments, and make the adjustment more flexible; by adjusting the effective area of ​​the air outlet, the temperature of the entire temperature range in the compartment can be accurately set, making the temperature control more precise.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] The orientations mentioned in this specification are based on the orientation of the air duct adjustment structure of the air-cooled refrigeration equipment of this utility model when it is working normally. They do not limit the orientation during storage and transportation, but only represent relative positional relationships, not absolute positional relationships.

[0023] like Figures 1 to 3 As shown, a duct adjustment structure for an air-cooled refrigeration device includes a fan 1. A rotating cover 2 is rotatably mounted on the front side of the fan 1. The rotating cover 2 includes a rotating plate 3. A vent 4 is provided on the surface of the rotating plate 3. A windbreak wall 5 extending rearward from the surface of the rotating plate 3 is provided on the rear side of the rotating plate 3. A fixed cover 6 is fixedly mounted on the rear side of the fan 1. The fixed cover 6 includes a base plate 7 and an annular side plate 8 extending forward from the surface of the base plate 7. The rotating cover 2, the fixed cover 6, and the fan 1 are coaxially arranged. The windbreak wall 5 is sleeved on the inner side of the annular side plate 8, thereby forming a closed windbreak structure around the fan 1. An air outlet 9 is provided on the side of the windbreak structure. There are two air outlets 9, symmetrically arranged on both sides of the central axis of the fan 1.

[0024] A large gear 10 is fixedly connected to the front side of the rotating cover 2. The large gear 10 meshes with a small gear 11, and the small gear 11 is connected to a motor 12. The motor 12 drives the small gear 11 to rotate, and the small gear 11 drives the large gear 10 to rotate, thereby driving the rotating cover 2 to rotate. During the rotation of the rotating cover 2, when the air outlet 9 on one side gradually becomes larger, the air outlet 9 on the other side is gradually blocked and becomes smaller. Through this design, the air supply ratio of the two chambers can be flexibly adjusted, thereby realizing the dynamic adjustment of temperature distribution. Preferably, in this embodiment, the large gear 10 is an annular internal gear, and the small gear 11 is an external gear. The small gear 11 meshes with the inner side of the large gear 10, making the structure of the entire device more compact and saving installation space.

[0025] like Figure 2 As shown, the windbreak wall 5 is divided into two parts by two air outlets 9. Each windbreak wall 5 has an arc-shaped first air guide plate 13 on its inner side. The first air guide plate 13 starts from a certain point on the inner side of the air outlet 9 and gradually expands towards the outer periphery of the rotating plate 3, with its endpoint located on the windbreak wall 5. The two arc-shaped first air guide plates 13 are arranged in the shape of a double volute curve on the rotating plate 3.

[0026] The starting point of the first air guide plate 13 and the ending point of the windbreak wall 5 are on the same radial line; a second air guide plate 14 is connected between the starting point of the windbreak wall 5 and the first air guide plate 13. The second air guide plate 14 is an arc-shaped plate with its opening facing the air outlet 9. Both the first air guide plate 13 and the second air guide plate 14 guide the air blown out by the fan 1.

[0027] Furthermore, the thickness of the windbreak wall 5 gradually decreases at the end point to form a guide surface 15, which facilitates the rotation of the rotating cover 2 within the fixed cover 6 and prevents it from getting stuck.

[0028] Furthermore, the outer diameter of the windbreak wall 5 is the same as the outer diameter of the rotating plate 3, and the outer diameter of the annular side plate 8 is the same as the outer diameter of the bottom plate 7 of the fixed cover 6, making the structure more reasonable, the size of the rotating cover 2 larger, the internal space larger, and the space fully utilized.

[0029] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
