[0042] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0043] In some technologies, the storage area of the refrigerator with air-drying function can only realize air-drying function, and cannot realize storage function. In order to solve the technical problem, the present application provides an air duct assembly and a refrigerator. The structures of the air duct assembly and the refrigerator will be described below:

[0044] For example, the refrigerator with air-drying function is provided with an air-drying area. The air-drying function of the refrigerator is only started when needed. Due to the air duct structure, the food materials placed in the air-drying area are directly blown by the air. Under normal circumstances, the air-drying area cannot store food materials. How to ensure that the air duct structure can meet the requirements of the two use states at the same time is a problem that needs to be solved at present.

[0045] As shown in Fig. 1, it is a structural schematic diagram of a box 1 according to an embodiment of the present application. Figure 2

[0046] In view of the above problems, the first aspect of the present application provides an air duct assembly, which comprises:

[0047] ​The refrigeration air duct 2 and the refrigeration space are arranged in the cabinet 1; the refrigeration air duct 2 is communicated with the refrigeration space; the refrigeration space is provided with a drying function and a storage function; when the refrigeration space is set as the drying function, the air speed of the refrigeration air duct 2 is increased, and the cold air is directly blown to the bottom of the refrigeration space, so that the food placed in the refrigeration space can be dried; when the refrigeration space is set as the storage function, the air speed of the refrigeration air duct 2 is reduced, and the cold air is uniformly blown into the refrigeration space, so that the refrigeration requirement of the food can be met, and the storage function of the food can be realized.

[0048] For example, the drying function and the storage function of the refrigerator can be controlled by a button or a display panel of the refrigerator, which is not limited herein. The running power of the refrigeration device can be adjusted by the control buttons corresponding to the drying function and the storage function. When the refrigerator is in the drying function, the running power of the refrigeration device is large, and the cold air speed entering the refrigeration space is large. When the refrigerator is in the storage function, the running power of the refrigeration device is small, and the cold air speed entering the refrigeration space is small.

[0049] As shown in Figure 1 , it is a structure schematic diagram of the air duct assembly in the application.

[0050] As shown in Figure 3 and Figure 4 , it is a structure schematic diagram of the refrigeration air duct 2 in the cabinet 1 in the application.

[0051] The refrigeration air duct 2 comprises:

[0052] The refrigeration chamber 21 is provided with an air inlet 211 and an air outlet 212, and the air outlet 212 is arranged in the refrigeration space. The refrigeration chamber 21 is used for placing the air duct assembly, which comprises a wing plate 22, a stop block 23 and the like. One end of the refrigeration chamber 21 is communicated with the refrigeration device, and the refrigeration chamber 21 transmits cold air from the air inlet 211 to the air outlet 212 to provide cold air to the refrigeration space.

[0053] As shown in Figures 5 to 7 , it is a structure schematic diagram of the refrigeration air duct 2 in the application.

[0054] In addition, the wing plate 22 arranged in the refrigeration chamber 21 comprises:

[0055] The wing plate 22 is rotationally connected in the refrigeration chamber 21, and the wing plate 22 is provided with a first face and a second face. The wing plate 22 is used for adjusting the transmission direction of the cold air, so as to realize the storage function and the drying function of the refrigeration space at the same time.

[0056] A stop block 23 is arranged opposite to the side wall of the refrigeration chamber 21, and the projection of the wing plate 22 in the direction of the stop block 23 completely covers the stop block 23; the stop block 23 is used to abut against the wing plate 22 to realize the storage function of the refrigeration space.

[0057] When the refrigeration space is set to the air-drying function, the wing plate 22 abuts against the top surface of the refrigeration chamber 21, and the cold air entering the air inlet 211 flows to the air outlet 212 through the first surface of the wing plate 22; when the refrigeration space is set to the storage function, the wing plate 22 abuts against the stop block 23, and the cold air entering the air inlet 211 flows to the air outlet 212 through the first surface and the second surface of the wing plate 22.

[0058] The application provides a kind of air duct assembly, when the refrigeration space is set to the air-drying function, by adjusting the shape of the wing plate 22 arranged in the refrigeration chamber 21, when the wing plate 22 is controlled to abut against the top surface of the refrigeration chamber 21, the cold air from the air inlet 211 flows to the air outlet 212 through the first surface of the wing plate 22 and the bottom surface of the refrigeration chamber 21, since the pipe diameter gradually decreases when the cold air flows from the air inlet 211 to the air outlet 212, so the wind speed gradually increases, thereby air-drying treatment is carried out on the food materials in the refrigeration space.

[0059] The application provides a kind of air duct assembly, which is designed to optimize the refrigeration and air-drying performance of the refrigerator to meet different usage scenarios. Specifically, the air duct assembly adjusts the position and shape of the wing plate 22 inside the refrigeration chamber 21, effectively controls the flow direction and speed of the cold air, and meets the different needs of the refrigerator in air-drying and storage modes. In the air-drying function mode, the user can adjust the wing plate 22 to tightly fit the top surface of the refrigeration chamber 21 through the control mechanism. When the cold air enters from the air inlet 211, flows along the first surface of the wing plate 22 and the bottom surface of the refrigeration chamber 21, and reaches the air outlet 212, the flow speed of the cold air naturally increases due to the gradual narrowing of the air duct, forming a strong air-drying effect. This design not only speeds up the air circulation in the refrigeration space, but also effectively increases the wind speed, so that the moisture on the surface of the food materials can evaporate quickly, achieving the purpose of efficient air-drying, especially suitable for food material preservation scenarios that require rapid drying.

[0060] When the refrigerator switches to the storage function mode, the position of the wing plate 22 needs to be adjusted accordingly so that it is in contact with the preset stopper 23. At this time, after the cold air flows into the air inlet 211, its flow path becomes more complex and dispersed: the cold air not only travels along the wall of the refrigeration chamber 21, but also passes through the first and second surfaces of the wing plate 22, and finally converges at the air outlet 212, so that the distribution of cold air in the refrigeration space is more uniform, avoiding the direct blowing of cold air on the surface of food materials, reducing the risk of food material damage due to local overcooling, and ensuring the freshness and taste of food materials during storage. At the same time, the uniformly distributed cold air can also effectively improve the temperature consistency of the entire refrigeration space, providing a more stable storage environment for food materials. In summary, the air duct assembly proposed in the present application realizes intelligent control of the refrigerator air cooling system by adjusting the position and shape of the wing plate 22, which not only meets the needs of high-efficiency wind speed and directional air flow in the air-drying mode, but also takes into account the requirements of temperature uniformity and food material protection in the storage mode.

[0061] As shown in Figure 9 , it is a structural schematic diagram of the refrigeration chamber 21 in the present application.

[0062] In this embodiment, the side wall of the refrigeration chamber 21 is oppositely provided with a shaft hole 213; the shaft hole 213 is oppositely provided on the side wall of the refrigeration chamber 21, and is provided on the side close to the air outlet 212; the shaft hole 213 is used to install the wing plate 22.

[0063] As shown in Figure 8 , it is a structural schematic diagram of the wing plate 22 in the present application.

[0064] One side of the wing plate 22 is provided with a connecting shaft 221, which is provided on one side of the wing plate 22 along the length direction of the wing plate 22; the length of the connecting shaft 221 is slightly greater than the length of the wing plate 22, and the part of the connecting shaft 221 exceeding the length of the wing plate 22 serves as a connecting end and is clamped with the shaft hole 213, so that the wing plate 22 can be rotatably connected to the refrigeration chamber 21.

[0065] Among them, the wing plate 22 is rotatably connected to the refrigeration chamber 21 by clamping the connecting shaft 221 in the shaft hole 213.

[0066] In this embodiment, the curvature of the second face is set to be greater than that of the first face, which, by virtue of aerodynamic principles, significantly improves the efficiency of the entire structure during the refrigeration process. In this application, the curvature of the first face of the wing plate 22 is set to be less than that of the second face. When the cold air from the air inlet 211 enters the interior of the refrigeration chamber 21, a natural lift effect is provided for the wing plate 22. It is worth noting that the upper and lower surfaces of the wing plate 22 exhibit significant asymmetry in shape: the upper surface (i.e., the second face) is relatively convex, while the lower surface (i.e., the first face) is relatively flat, which further enhances the generation of lift effect. When the cold air flows along the surface of the wing plate 22, due to the greater curvature of the second face, the path of the cold air is relatively long, and according to Bernoulli's principle, the flow rate is accelerated at this point, thereby causing the pressure in this region to decrease; on the contrary, the flow rate of the cold air on the first face (lower surface) is slower, so the pressure is relatively high. Because of the pressure difference between the upper and lower surfaces, an upward lift is created for the wing plate 22.

[0067] For example, when the refrigeration space is set for storage function, the air speed of the air outlet 212 does not exceed the set air speed, at this time the lift force of the cold air on the wing plate 22 is less than the torque between the connecting shaft 221 and the shaft hole 213 relative to the torque of the gravity of the wing plate 22 relative to the connecting shaft 221, the other end of the wing plate 22 is in abutment with the stopper 23, the wing plate 22 is parallel to the air direction, and the air duct assembly delivers low-speed horizontal cold air into the storage space, the air circulation in the storage space is smooth, and the air temperature in the space is relatively uniform.

[0068] For example, when the refrigeration space is set for air drying function, the air speed of the air outlet 212 is greater than the set air speed, at this time the lift force of the cold air on the wing plate 22 is greater than the torque between the connecting shaft 221 and the shaft hole 213 relative to the torque of the gravity of the wing plate 22 relative to the connecting shaft 221, the wing plate 22 rotates upward around the connecting shaft 221 by a certain angle, the other end of the wing plate 22 is in abutment with the upper edge of the air outlet 212, the air direction of the air outlet 212 blows air obliquely downward along the wing plate 22, and the pipe diameter gradually decreases from the air inlet 211 to the air outlet 212, so that the air speed gradually increases, and the cold air from the air outlet 212 directly blows onto the surface of the food, achieving the purpose of air drying.

[0069] The wing plate 22 structure provided by the application cannot provide any additional power, and only relies on the transmitted cold air to realize the storage and air drying functions in the refrigeration space. Compared with the method of arranging an additional motor at the shaft hole 213, the wing plate 22 structure provided by the application does not need to be arranged with an additional power consumption device, and the user does not need to equip the structure with an additional power consumption device, thereby greatly saving the precious internal use space of the refrigerator, and making the internal layout of the refrigerator more compact and efficient. At the same time, since the additional motor drive is omitted, the overall energy consumption of the refrigerator is also significantly reduced.

[0070] In this embodiment, when the wing plate 22 abuts against the stop block 23, the direction of the wing plate 22 is parallel to the bottom surface of the refrigeration chamber 21.

[0071] For example, when the wing plate 22 abuts against the stop block 23, the refrigeration space is arranged to be used for storage function, and the air duct assembly transports the low-speed horizontal cold air into the storage space. The air circulation in the storage space is smooth, and the air temperature in the space is relatively uniform. In this embodiment, when the wing plate 22 abuts against the stop block 23, the direction of the wing plate 22 is arranged to be parallel to the bottom surface of the refrigeration chamber 21, so that the cold air entering through the air inlet 211 can uniformly pass through the space formed by the first surface of the wing plate 22 and the lower surface of the refrigeration chamber 21, and the space formed by the second surface of the wing plate 22 and the upper surface of the refrigeration chamber 21, thereby realizing the technical effects of transporting the low-speed horizontal cold air into the refrigeration space, smooth air circulation in the refrigeration space, and relatively uniform air temperature in the refrigeration space.

[0072] In this embodiment, when the refrigeration space is arranged for air drying function, the cold air entering through the air inlet 211 has a first wind speed; when the refrigeration space is arranged for storage function, the cold air entering through the air inlet 211 has a second wind speed; the first wind speed is greater than the second wind speed.

[0073] For example, when the refrigeration space is arranged for storage function, the air speed of the air outlet 212 does not exceed the set air speed, at this time, the lift force of the cold air on the wing plate 22 is relatively smaller than the torque between the connecting shaft 221 and the shaft hole 213, the other end of the wing plate 22 abuts against the stop block 23, the wing plate 22 is parallel to the air direction, the air duct assembly transports the low-speed horizontal cold air into the storage space, the air circulation in the storage space is smooth, and the air temperature in the space is relatively uniform. The second wind speed is less than the set air speed. It can be understood that when the wind speed is the second wind speed, the lift force is insufficient to support the wing plate 22 to abut against the upper surface of the refrigeration chamber 21, thereby abutting against the stop block 23, and realizing the storage function of the refrigeration space.

[0074] Exemplarily, when the refrigeration space is set to be used in the air-drying function, the air outlet 212 has a wind speed greater than the set wind speed. At this time, the lift force formed by the cold air on the wing plate 22 is greater than the torque generated between the connecting shaft 221 and the shaft hole 213, and the wing plate 22 rotates upward around the connecting shaft 221 by a certain angle. The other end of the wing plate 22 abuts against the upper edge of the air outlet 212, the air outlet 212 blows air obliquely downward along the wing plate 22, and the pipe diameter of the cold air from the air inlet 211 to the air outlet 212 gradually decreases, so that the wind speed gradually increases. The cold air from the air outlet 212 directly blows to the surface of the food material, achieving the purpose of air-drying. Wherein, the first wind speed is greater than the set wind speed. It can be understood that when the wind speed is the first wind speed, the generated lift force is sufficient to support the wing plate 22 to abut against the upper surface of the refrigeration chamber 21, realizing the air-drying function of the refrigeration space.

[0075] In this embodiment, the bottom surface of the refrigeration chamber 21 is provided with a notch 214, which is arranged on one side close to the air inlet 211. The projection of the notch 214 in the direction of the wing plate 22 covers the wing plate 22.

[0076] Exemplarily, when the refrigeration space is set to be used in the air-drying function, the air outlet 212 has a wind speed greater than the set wind speed. At this time, the air outlet 212 is only a part of the air outlet 212, because the cold air blown out from the first surface of the wing plate 22 is blocked by the bottom surface of the refrigeration chamber 21, resulting in that the transmission of the cold air is blocked, thereby affecting the air-drying function of the refrigeration space. In order to avoid the above problem, the bottom surface of the refrigeration chamber 21 is provided with a notch 214, wherein the projection of the notch 214 in the direction of the wing plate 22 covers the wing plate 22, that is, the cold air blown out from the first surface of the wing plate 22 is blown out from the notch 214. The food material placed in the refrigeration space is blown dry by the high-speed cold air, realizing the air-drying treatment of the food material.

[0077] In this embodiment, the abutting position of the wing plate 22 and the top surface of the refrigeration chamber 21 is provided with an elastic strip, and the elastic strip is arranged on the top surface of the refrigeration chamber 21 along the length direction of the refrigeration chamber 21. Wherein, the abutting position of the wing plate 22 and the stopper 23 is also provided with an elastic strip.

[0078] It can be understood that the wing plate 22, the wall surface of the refrigeration cavity 21 and the stop block 23 are all made of iron material, so as to prevent the wing plate 22 from making a sound when abutting against the top surface of the refrigeration cavity 21 and the stop block 23 when the refrigeration space switches the air-drying function and the storage function, thereby affecting the use experience of the user. The elastic strips are arranged at the abutting positions of the wing plate 22 and the top surface of the refrigeration cavity 21 and the abutting positions of the wing plate 22 and the stop block 23, so as to avoid the wing plate 22 from making a sound when abutting against the top surface of the refrigeration cavity 21 and the stop block 23.

[0079] It can be understood that the wing plate 22, the wall surface of the refrigeration cavity 21 and the stop block 23 are all made of iron material, so as to prevent the wing plate 22 from making a sound when abutting against the top surface of the refrigeration cavity 21 and the stop block 23 when the refrigeration space switches the air-drying function and the storage function, thereby affecting the use experience of the user. The elastic strips are arranged at the abutting positions of the wing plate 22 and the top surface of the refrigeration cavity 21 and the abutting positions of the wing plate 22 and the stop block 23, so as to avoid the wing plate 22 from making a sound when abutting against the top surface of the refrigeration cavity 21 and the stop block 23.

[0080] In this embodiment, the air duct assembly further comprises:

[0081] The cover plate 3 is slidingly connected to the opposite shelves 11 in the cabinet 1, and the drawer 4 is slidingly connected to the cabinet 1. The refrigeration space is formed between the cover plate 3 and the drawer 4. The drawer 4 is used for placing food materials to be stored or air-dried.

[0082] In this embodiment, the diameter of the air inlet 211 is greater than the diameter of the air outlet 212.

[0083] For example, when the cold air is transmitted in the refrigeration chamber 21, the flow rate of the cold air is affected by various factors, one of which is the diameter of the pipeline. Specifically, when the cold air flows from a pipeline with a large diameter into a pipeline with a small diameter, due to the reduction in the cross-sectional area of the pipeline, the volume of cold air passing through the cross-sectional area in the same time must also be reduced. In order to achieve this, the flow rate must be increased to ensure that the same volume of cold air is delivered through a smaller cross-sectional area in a shorter time. In order to increase the flow rate of the air outlet 212, the diameter of the air inlet 211 is set to be larger than the diameter of the air outlet 212, which on the one hand improves the air-drying function of the cabinet 1, and on the other hand saves the power consumption of the cabinet, and a smaller refrigeration device can be used to obtain a larger air speed.

[0084] The present application provides a kind of air duct assembly, by adjusting the air-drying function and storage function of the refrigeration space, so as to adjust the wind speed of the cold air into the refrigeration chamber 21, when the wind speed is larger, the refrigeration space is set to air-drying function, the adjusting wing plate 22 is closely attached to the top surface of the refrigeration chamber 21, and the cold air is blown out from the gap 214 after being blown out from the first surface of the wing plate 22, and the food material placed in the refrigeration space is blown dry due to the high-speed cold air, realizing the air-drying treatment of the food material. When the wind speed is smaller, the refrigeration space is set to storage function, and the cold air is transported into the refrigeration space through the space formed by the first surface of the wing plate 22 and the lower surface of the refrigeration chamber 21, and the space formed by the second surface of the wing plate 22 and the upper surface of the refrigeration chamber 21, so as to realize the transportation of low-speed horizontal cold air into the refrigeration space, the air circulation in the refrigeration space is smooth, and the air temperature in the refrigeration space is relatively uniform, realizing the storage function of the food material.

[0085] Compared with the current refrigerator with air-drying function, the refrigeration space provided by the present application can have air-drying function and storage function, increase the effective use area of the refrigerator, and achieve the above technical effects only by the cold air transmitted by the refrigeration device of the refrigerator, without the need for additional motor equipment, further increasing the effective use area of the refrigerator, and saving the manufacturing cost of the refrigerator.

[0086] The second aspect of the present application provides a refrigerator, comprising:

[0087] The air duct assembly according to any of the above embodiments.

[0088] It is worth noting that the effects of the above refrigerator embodiments during operation can refer to the effects of the above air duct assembly embodiments, which will not be repeated here.

[0089] The above detailed description of the embodiments of the present application is merely intended to provide a further detailed description of the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above is only a specific implementation of the embodiments of the present application, and is not used to limit the protection scope of the embodiments of the present application.
