Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] Refrigerators are common household appliances that keep food or other items at a constant low temperature. Refrigerators typically have a storage chamber for storing food or other items. Refrigerators also include a fan and a refrigeration system. The fan's air inlet is connected to the refrigeration system, and the fan's air outlet is directed toward the storage chamber, thereby lowering the temperature of the food or other items within the chamber. However, when the fan is used to blow air into the food or other items within the chamber, the food can dry out, resulting in poor food preservation. Utility Model Content

[0003] The embodiment of the present application provides a refrigerator that can solve the technical problem of poor food preservation effect of refrigerators.

[0004] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0005] The box body is formed with a receiving cavity;

[0006] A refrigeration system is provided in the box;

[0007] a fan, wherein the air inlet end of the fan is connected to the cooling end of the refrigeration system, and the air outlet end of the fan is used to output cold air to the accommodating cavity at least;

[0008] An air guide structure is provided on the box body; the air guide structure forms a plurality of air guide channels, a first end of the air guide channel is connected to the air outlet end of the fan, and a second end of the air guide channel extends toward the outside of the air guide structure;

[0009] The air guide structure is further provided with a plurality of air outlets, the plurality of air outlets are provided corresponding to the plurality of air guide channels, and the air guide channels are connected to the accommodating cavity through the air outlets;

[0010] The spoiler is provided in a plurality of numbers, and the plurality of spoilers are provided corresponding to the plurality of air outlets. The spoiler can be rotatably provided on the air guide structure to close or open the air outlets.

[0011] By setting up multiple air guide channels and air outlets, the cold air can be evenly distributed in the storage chamber, avoiding the cold air from being concentrated in one place, thereby reducing the drying of food.

[0012] The design of the air guide structure enables the cold air to be evenly distributed through multiple air guide channels;

[0013] The air outlet and the air guide channel are set correspondingly to ensure that the cold air can effectively enter the accommodation cavity;

[0014] The rotatable design of the spoiler makes the flow of cold air more controllable. The direction and flow of the cold air can be adjusted as needed. Users can adjust the output method of the cold air according to actual needs, providing higher flexibility of use. It can also prevent the cold air from blowing directly onto the surface of the food, preventing the surface of the food from drying out, fully retaining the original taste and flavor of the food, and better maintaining the freshness of the food.

[0015] In some embodiments of the present application, the first end of the spoiler is rotatably disposed on the wind guide structure, and the second end of the spoiler is close to the second end of the wind guide channel relative to the first end of the spoiler.

[0016] The first end of the spoiler is rotatably mounted on the air guide structure, so that the spoiler can be adjusted between different angles, thereby changing the direction and intensity of the airflow; the second end of the spoiler is positioned relative to the first end and is close to the second end of the air guide channel, which means that when the spoiler rotates, the first end of the spoiler sends air toward the accommodating cavity. By adjusting the position of the spoiler, the direction and intensity of the air supplied by the fan can be changed, thereby preventing strong wind from blowing directly onto the food, reducing moisture evaporation on the surface of the food, and preventing the food from drying out;

[0017] By properly adjusting the spoiler, the circulation path of cold air can be optimized, making the refrigeration system more efficient and reducing the energy consumption of the refrigerator.

[0018] In some embodiments of the present application, when the spoiler is in the first state, the spoiler closes the air outlet;

[0019] When the spoiler is in the second state, the spoiler opens the air outlet, the second end of the spoiler faces the accommodating cavity, and the second end of the spoiler faces the front side of the box.

[0020] When the spoiler is in the first position, the spoiler completely blocks the air outlet. This means that the cold air from the fan cannot directly enter the storage chamber, temporarily stopping the cooling of the food or other items in the storage chamber. The spoiler can be used intermittently to stop the direct blowing of cold air, reducing the rapid evaporation of moisture on the surface of the food, thereby preventing the food from drying out.

[0021] When the spoiler is in the second position, the spoiler opens the air outlet, allowing cool air to enter the storage chamber through the air outlet. At this time, the second end of the spoiler faces the interior of the storage chamber and points to the front of the box. This arrangement allows the cool air to be more evenly distributed within the storage chamber, avoiding direct airflow onto the food, reducing drying, and preventing localized overcooling or overheating, thereby improving freshness preservation.

[0022] In some embodiments of the present application, when the spoiler is in the first state, the first surface of the spoiler faces the accommodating cavity, and the first surface of the spoiler is flush with the air guide structure;

[0023] The second surface of the spoiler faces away from the accommodating cavity. A rotating portion is provided on the second surface of the spoiler. The spoiler is connected to the air guide structure via the rotating portion.

[0024] In the first state, the first surface of the spoiler is flush with the air guide structure, closing the air outlet, preventing cold air from blowing directly onto the food, reducing the evaporation of moisture on the surface of the food, and thus preventing the food from drying out; when the spoiler rotates to the second state, the air outlet is open, and cold air can enter the containing cavity. The design of the spoiler enables the cold air to be more evenly distributed in the containing cavity, avoiding local overcooling or overheating and improving the preservation effect; at the same time, the first surface of the spoiler is flush with the air guide structure, which not only improves the sealing of the spoiler to the air outlet, but also improves the aesthetics of the interior of the containing cavity, avoiding the creation of sanitary dead corners.

[0025] The spoiler is connected to the air guide structure through the rotating part, so that the spoiler can rotate or swing between the first state and the second state, thereby providing a flexible adjustment method that can be adjusted according to actual needs to meet the preservation requirements of different food ingredients.

[0026] In some embodiments of the present application, a plurality of reinforcing ribs are provided on the second surface of the spoiler, and the reinforcing ribs are at least used to support the spoiler.

[0027] The reinforcement ribs increase the overall rigidity of the spoiler, making it less likely to deform or break when subjected to fan airflow pressure or other external forces, thereby extending the service life of the spoiler. Since the spoiler needs to be precisely adjusted and positioned in different states, the support of the reinforcement ribs ensures that the spoiler can remain stable during rotation or swinging, avoiding adjustment errors caused by deformation.

[0028] By increasing the rigidity and stability of the spoiler, the direction and intensity of the airflow can be more effectively controlled, thereby optimizing the distribution of cold air in the containment cavity, reducing the drying of food, and improving the preservation effect; the design of the reinforcement ribs enables the spoiler to withstand greater mechanical stress and environmental changes during long-term use, thereby improving the overall durability and reliability of the refrigerator.

[0029] In some embodiments of the present application, the rotating portion is a driving member;

[0030] The number of the driving members is set to be multiple, and the multiple driving members are correspondingly provided to the multiple spoilers, and the driving members drive the corresponding spoilers to rotate;

[0031] Alternatively, the number of the driving members is smaller than the number of the spoilers, and at least one driving member drives a plurality of the spoilers to rotate.

[0032] By setting each driving member to correspond to a spoiler, each spoiler can be rotated independently by the control of the driving member, thereby accurately controlling the direction and intensity of the wind flow, which can achieve fine adjustment of the wind flow and reduce the situation where the wind blows directly onto the food;

[0033] By setting the number of driving members to be less than the number of spoilers, one driving member can simultaneously drive multiple spoilers to rotate through a mechanical connection or linkage device. This configuration can simplify the structure and reduce manufacturing and maintenance costs, while still effectively adjusting the direction and intensity of the wind flow.

[0034] In some embodiments of the present application, the accommodating cavity includes a plurality of accommodating areas, and the plurality of accommodating areas are arranged in sequence along the vertical direction;

[0035] The plurality of air guide channels form a plurality of channel paths, the plurality of channel paths are arranged corresponding to the plurality of accommodating areas, and the channel paths include at least one of the air guide channels.

[0036] Through the above settings, each storage area can be used to store food of different types or with different temperature requirements; each channel path is set corresponding to a storage area, that is, each storage area has an independent cold air channel for guiding cold air into the corresponding storage area, which can ensure that the cold air is evenly distributed to each storage area, avoiding overcooling or overheating in some areas; the independent channel path can optimize the flow direction and speed of the cold air, reduce the situation where strong winds blow directly onto the food, thereby reducing the drying of the food; it can also maintain a constant low temperature in each storage area, thereby improving the preservation effect of the food.

[0037] In some embodiments of the present application, each of the accommodating areas corresponds to two of the air outlets, and the two air outlets are arranged in a horizontal direction;

[0038] In the two air outlets in the same accommodating area, when the two spoilers open the air outlets, the directions of the two spoilers are opposite.

[0039] By setting two air outlets in each storage area and arranging the two air outlets in a horizontal direction, it can be ensured that the cold air can evenly cover the entire storage area, forming an orderly flow path, avoiding turbulence and dead corners, and avoiding overcooling or overheating in certain areas, which affects the preservation of food, and can also improve the cooling efficiency; each air outlet is equipped with a spoiler. When the spoilers of the two air outlets are open at the same time, they face opposite directions. In this way, one spoiler guides the cold air to the left and the other spoiler guides the cold air to the right. This design can make the cold air circulate in the storage area, avoid blowing directly onto the food, and thus reduce the drying of the food; by optimizing the cold air distribution through the above settings, a constant low temperature can be maintained in each storage area, thereby improving the preservation effect of food.

[0040] In some embodiments of the present application, the first end of the spoiler is rotatably disposed on the air guide structure, and the second end of the spoiler is closer to the second end of the air guide channel relative to the first end of the spoiler;

[0041] The box body has a left side wall and a right side wall arranged opposite to each other in the horizontal direction; in the two air outlets in the same accommodating area, the first end of one of the spoilers is close to the left side wall, and the first end of the other spoiler is close to the right side wall.

[0042] By making the first end of the spoiler rotatably arranged on the air guide structure, the spoiler can adjust its angle as needed to change the direction and intensity of the airflow; the arrangement of the second end of the spoiler can ensure that the spoiler can effectively guide and disperse the airflow, avoiding direct blowing onto the food, and at the same time ensuring that the cold air is blown from the spoiler into the storage area; by arranging the spoiler in the two air outlets of the same storage area, the airflow can be more evenly distributed in the storage area, avoiding excessive airflow in local areas, avoiding overcooling or overheating in local areas, ensuring that the temperature in the entire storage area is more uniform, and helping to keep the food fresh.

[0043] In a second aspect, an embodiment of the present application provides a refrigerator, comprising:

[0044] A box body, wherein the box body is formed with a receiving cavity;

[0045] A refrigeration system is provided in the box;

[0046] a fan, wherein the air inlet end of the fan is connected to the cooling end of the refrigeration system, and the air outlet end of the fan is used to output cold air to the accommodating cavity at least;

[0047] an air guide structure, wherein the air guide structure forms a plurality of air guide channels, wherein a first end of the air guide channel is connected to an air outlet of the fan, and a second end of the air guide channel extends toward an outer side of the air guide structure;

[0048] The air guide structure is further provided with a plurality of air outlets, the plurality of air outlets are provided corresponding to the plurality of air guide channels, and the air guide channels are connected to the accommodating cavity through the air outlets;

[0049] A spoiler, wherein the number of the spoilers is set to be multiple, and the multiple spoilers are correspondingly arranged with the multiple air outlets;

[0050] The spoiler can be rotatably arranged on the air guide structure to close or open the air outlet; when the spoiler opens the air outlet, the spoiler can be used to adjust the air outlet direction of the air outlet. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] As described in the background technology, in the related art, when a refrigerator uses a fan to supply air to food or other items in the storage cavity, the cold air blows directly onto the food. The strong airflow will directly act on the surface of the food, causing local over-drying, accelerating the evaporation of moisture on the surface of the food, and the food is prone to air-drying, which will cause the refrigerator to have a poor preservation effect on the food.

[0071] In view of this, the refrigerator in the embodiment of the present application is provided with multiple air guide channels and air outlets, so that the cold air can be evenly distributed in the accommodating cavity, avoiding the cold air from being concentrated in a certain position, thereby reducing the drying of the food; by designing the air guide structure, the cold air can be evenly distributed through multiple air guide channels; by designing the corresponding arrangement of the air outlet and the air guide channel, it is ensured that the cold air can effectively enter the accommodating cavity; by making the spoiler rotatable, the flow of cold air is made more controllable, and the flow direction and flow rate of the cold air can be adjusted as needed. The user can adjust the output method of the cold air according to actual needs, providing higher flexibility of use, and can avoid the cold air from blowing directly onto the surface of the food, preventing the surface of the food from drying, fully retaining the original taste and flavor of the food, and better maintaining the freshness of the food.

[0079] Reference Figure 1-Figure 7 The utility model provides a refrigerator, including a box body, which can form a accommodating cavity.

[0080] The refrigerator also includes a refrigeration system, which can be arranged in the box body.

[0081] The refrigerator's refrigeration system includes at least: a compressor, which increases the pressure and temperature of the refrigerant gas by compressing it. The compressed, high-temperature, high-pressure gas enters the condenser; a condenser, usually located at the back or bottom of the refrigerator, where the high-temperature, high-pressure refrigerant gas dissipates heat, turning it into a high-pressure liquid. This heat dissipation process is usually achieved through air flow or water cooling; a throttling device (such as a capillary tube or expansion valve), which reduces the pressure of the high-pressure liquid refrigerant, turning it into a low-pressure, low-temperature liquid. This process causes the refrigerant temperature to drop significantly; an evaporator, usually located inside the refrigerator, where the low-temperature, low-pressure liquid refrigerant absorbs heat and evaporates into a gas. This heat absorption process lowers the temperature around the evaporator, thereby achieving the cooling effect; refrigerant, which is the working fluid circulating in the refrigeration system. Common refrigerants include Freon, ammonia (NH3), and more environmentally friendly alternatives (such as R-600a); a piping system, which connects the above components and ensures that the refrigerant can circulate through the system; and a control system, which includes temperature sensors, a control panel, and an electronic control unit to monitor and adjust the temperature inside the refrigerator to ensure the normal operation of the refrigeration system.

[0082] Freon is a term generally used to refer to a class of refrigerants containing chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). These chemicals are widely used in refrigeration, air conditioning, and other industrial applications. Common Freons include: R-12 (CCl2F2): dichlorodifluoromethane, widely used in refrigerators and air conditioners; R-22 (CHClF2): chlorodifluoromethane, commonly used in air conditioning and refrigeration systems; and R-134a (C2H2F4): tetrafluoroethane, commonly used in car air conditioners and home refrigerators.

[0083] Ammonia (NH3) is a common refrigerant, particularly in industrial refrigeration and large-scale refrigeration systems. Ammonia has high refrigeration efficiency and a high refrigeration capacity per unit mass. It contains no chlorine or fluorine, making it harmless to the ozone layer. It also has a low production cost.

[0084] R-600a, also known as isobutane (C4H10), is a natural refrigerant that has been widely used in household and commercial refrigeration equipment in recent years due to its environmentally friendly properties and good refrigeration performance. It does not contain chlorine and fluorine and is harmless to the ozone layer. R-600a has good thermal conductivity, which helps improve the efficiency of refrigeration systems; R-600a has a low production cost.

[0085] The refrigerator further includes a fan 100, an air inlet end of the fan 100 can be connected to a cold supply end of the refrigeration system, and an air outlet end of the fan 100 is used to output cold air to the accommodating cavity at least.

[0086] It's important to note that fan 100 here refers to the refrigerator compartment fan, also known as the evaporator fan. It plays a key role in the refrigerator's cooling process. Its primary function is to evenly distribute the cold air generated by the evaporator to all parts of the refrigerator, ensuring uniform and stable internal temperature. Fan 100 is typically installed near the evaporator. When activated, it generates airflow, drawing in the cool air around the evaporator.

[0087] The refrigerator further includes an air guide structure 200 disposed on the refrigerator body.

[0088] After the fan 100 is started, the cold air is sent into the refrigerator through the wind guide structure 200.

[0089] The wind guide structure 200 may form a plurality of wind guide channels 210 , and a first end of the wind guide channel 210 may be connected to the air outlet of the fan 100 . A second end of the wind guide channel 210 may extend toward the outside of the wind guide structure 200 .

[0090] The air guide structure 200 enables the cool air to be evenly distributed through the plurality of air guide channels 210 .

[0091] The air guide structure 200 may also have multiple air outlets 220 .

[0092] A plurality of air outlets 220 may be provided corresponding to each air guiding channel 210 , and the air guiding channel 210 may connect the air outlets 220 with the accommodating cavity.

[0093] By providing a plurality of air guide channels 210 and air outlets 220 , the cold air can be evenly distributed in the accommodating cavity, avoiding the cold air from being concentrated in a certain location, thereby reducing the drying of the food.

[0094] The refrigerator further includes a spoiler 300 , and the number of the spoiler 300 can be set to multiple. Multiple spoilers 300 can be set corresponding to multiple air outlets 220 . The spoiler 300 can be rotatably set on the air guide structure 200 to close or open the air outlet 220 .

[0095] The rotatable design of the spoiler 300 makes the flow of cold air more controllable. The direction and flow of the cold air can be adjusted as needed. Users can adjust the output method of the cold air according to actual needs, providing higher flexibility of use. It can also prevent the cold air from blowing directly onto the surface of the food, preventing the surface of the food from drying out, fully preserving the original taste and flavor of the food, and better maintaining the freshness of the food.

[0096] It should be understood that the air guide structure is mainly used in the refrigerator compartment.

[0097] In some possible implementations, the first end of the spoiler 300 is rotatably disposed on the wind guide structure 200 , and the second end of the spoiler 300 is closer to the second end of the wind guide channel 210 relative to the first end of the spoiler 300 .

[0098] The first end of the spoiler 300 can be rotatably set on the air guide structure 200, so that the spoiler 300 can be adjusted between different angles, thereby changing the direction and intensity of the airflow; the second end of the spoiler 300 is located near the second end of the air guide channel 210 relative to the first end, which means that when the spoiler 300 rotates, the first end of the spoiler 300 supplies air toward the accommodating cavity. By adjusting the position of the spoiler 300, the direction and intensity of the air supplied by the fan 100 can be changed, thereby avoiding strong wind blowing directly onto the food, reducing the evaporation of moisture on the surface of the food, and preventing the food from drying out.

[0099] By properly adjusting the spoiler 300, the circulation path of the cold air can be optimized, the efficiency of the refrigeration system can be improved, and the energy consumption of the refrigerator can be reduced.

[0100] In some possible implementations, when the spoiler 300 is in the first state, the spoiler 300 may close the air outlet 220 .

[0101] At this time, the cold air sent by the fan 100 cannot directly enter the accommodating cavity, thereby temporarily stopping the cooling of the food or other items in the accommodating cavity; the spoiler 300 can be used intermittently to stop the direct blowing of cold air, reduce the rapid evaporation of moisture on the surface of the food, and prevent the food from drying out.

[0102] When the spoiler 300 is in the second state, the spoiler 300 may open the air outlet 220 , the second end of the spoiler 300 may face the accommodating cavity, and the second end of the spoiler 300 may face the front side of the box.

[0103] At this time, cold air can enter the storage cavity through the air outlet 220. At this time, the second end of the spoiler 300 is facing the inside of the storage cavity and pointing to the front side of the box. This setting allows the cold air to be more evenly distributed in the storage cavity, avoiding direct blowing onto the food, reducing air drying, and avoiding local overcooling or overheating, thereby improving the preservation effect.

[0104] In some possible implementations, when the spoiler 300 is in the first state, the first surface of the spoiler 300 may face the accommodating cavity, and the first surface of the spoiler 300 may be flush with the air guide structure 200 .

[0105] In the first state, the first surface of the spoiler 300 is flush with the air guide structure 200, closing the air outlet 220, preventing cold air from blowing directly onto the food, reducing the evaporation of moisture on the surface of the food, and thus preventing the food from drying out; when the spoiler 300 rotates to the second state, the air outlet 220 is open, and cold air can enter the receiving cavity. The design of the spoiler 300 enables the cold air to be more evenly distributed in the receiving cavity, avoiding local overcooling or overheating and improving the preservation effect; at the same time, the first surface of the spoiler 300 is flush with the air guide structure 200, which not only improves the sealing of the spoiler 300 to the air outlet 220, but also improves the aesthetics of the interior of the receiving cavity and avoids creating sanitary dead corners.

[0106] The second surface of the spoiler 300 may face away from the accommodating cavity. The second surface of the spoiler 300 may be provided with a rotating portion, and the spoiler 300 may be connected to the air guide structure 200 through the rotating portion.

[0107] The spoiler is connected to the air guide structure through the rotating part, so that the spoiler can rotate or swing between the first state and the second state, thereby providing a flexible adjustment method that can be adjusted according to actual needs to meet the preservation requirements of different food ingredients.

[0108] refer to Figures 8-10 In some possible implementations, the second surface of the spoiler 300 may be provided with a plurality of reinforcing ribs 310 , and the reinforcing ribs 310 are at least used to support the spoiler 300 .

[0109] The reinforcing ribs 310 increase the overall rigidity of the spoiler 300, making it less likely to deform or break when subjected to fan airflow pressure or other external forces, thereby extending the service life of the spoiler 300; since the spoiler 300 needs to be precisely adjusted and positioned in different states, the supporting role of the reinforcing ribs 310 ensures that the spoiler 300 can remain stable during rotation or swinging, avoiding adjustment errors caused by deformation.

[0110] By increasing the rigidity and stability of the spoiler 300, the direction and intensity of the airflow can be more effectively controlled, thereby optimizing the distribution of cold air in the storage cavity, reducing the drying of food, and improving the preservation effect; the design of the reinforcing ribs 310 enables the spoiler 300 to withstand greater mechanical stress and environmental changes during long-term use, thereby improving the overall durability and reliability of the refrigerator.

[0111] A plurality of reinforcing ribs 310 are provided on the second surface of the spoiler 300. This makes the ribs 310 invisible when viewed from the receiving cavity, enhancing the appearance. These ribs 310 can be arranged vertically or horizontally. The design and arrangement of the ribs 310 can be optimized based on actual needs to provide optimal support.

[0112] In some possible implementations, the reinforcing rib 310 is integrally cast with the spoiler 300 to enhance the structural strength of the spoiler 300 .

[0113] refer to Figure 8 In some possible implementations, the rotating portion may be a driving member 400 .

[0114] For example, the drive element 400 may utilize a pulse motor. A pulse motor (also known as a stepper motor) controls its rotation angle by receiving pulse signals. Each pulse signal corresponds to a fixed angle (step angle) of motor rotation. By controlling the number and frequency of pulses, the motor's speed and position can be precisely controlled. Pulse motors not only offer precise control but also, due to the lack of brushes and commutators, have a simple structure, high reliability, and a long service life.

[0115] It should be noted that the drive element 400 may also utilize a servo motor. A servo motor is precisely controlled via a closed-loop control system, typically including a position sensor (such as an encoder) and a controller. Servo motors offer high precision, high dynamic response, and powerful torque output, making them suitable for demanding control systems.

[0116] The driver 400 can also utilize a pneumatic drive device. A pneumatic drive device utilizes compressed air pressure to drive an actuator and typically includes components such as a cylinder, a valve, and a compressor. Pneumatic drives offer fast response times, simple structures, and easy maintenance. As long as the driver 400 can control the rotation of the spoiler 300, the present embodiment does not impose any additional restrictions on the specific structure of the driver 400.

[0117] The number of the driving members 400 is set to be multiple, and the multiple driving members 400 are correspondingly arranged to the multiple spoilers 300, and the driving members 400 drive the corresponding spoilers 300 to rotate.

[0118] During use, the output end of the driving member 400 may be connected to the first end of the spoiler 300 to control the rotation of the spoiler 300 .

[0119] By setting each driving member 400 to correspond to a spoiler 300, each spoiler 300 can be rotated independently by the control of the driving member 400, so as to accurately control the direction and intensity of the wind flow, realize fine adjustment of the wind flow, and reduce the situation where the wind blows directly onto the food.

[0120] Alternatively, the number of the driving members 400 is smaller than the number of the spoilers 300 , and at least one driving member 400 drives a plurality of spoilers 300 to rotate.

[0121] By setting the number of driving members 400 to be less than the number of spoilers 300, one driving member 400 can simultaneously drive multiple spoilers 400 to rotate through a mechanical connection or linkage device. This configuration can simplify the structure and reduce manufacturing and maintenance costs, while still effectively adjusting the direction and intensity of the wind flow.

[0122] For example, a driving member 400 can drive multiple spoilers 300 via a worm, which is connected to the output end of the driving member 400. The worm and worm gear transmit the rotational motion of the driving member 400 to the multiple spoilers 300. The worm drive has a self-locking function, which can prevent the spoilers from rotating freely when not driven.

[0123] One driving member 400 can also drive multiple spoilers 300 through gear transmission. As long as the driving member 400 can drive multiple spoilers 300, the embodiment of the present application does not impose too many restrictions on the connection relationship between the driving member 400 and the multiple spoilers 300.

[0124] During use, the driving member 400 may be installed at the air guide structure 200 .

[0125] In some possible implementations, the accommodating cavity may include several accommodating areas, and the several accommodating areas may be arranged in sequence along the vertical direction.

[0126] Through the arrangement of the above embodiments, each storage area can be used to store food of different types or with different temperature requirements.

[0127] The plurality of air guiding channels 210 may form a plurality of channel paths. The plurality of channel paths and the plurality of accommodating areas may be arranged correspondingly. The channel path includes at least one air guiding channel 210 .

[0128] Each channel path is set up corresponding to a storage area, that is, each storage area has an independent cold air channel for guiding cold air into the corresponding storage area, which can ensure that the cold air is evenly distributed to each storage area, avoiding overcooling or overheating in some areas; the independent channel path can optimize the flow direction and speed of cold air, reduce the situation where strong wind blows directly onto the food, thereby reducing the drying of the food; it can also maintain a constant low temperature in each storage area, thereby improving the preservation effect of the food.

[0129] In some possible implementations, each accommodating area may correspond to two air outlets 220 , and the two air outlets 220 may be arranged in a horizontal direction.

[0130] Through the arrangement of the above embodiment, it can be ensured that the cold air can evenly cover the entire accommodating area, forming an orderly flow path, avoiding turbulence and dead corners, and avoiding certain areas from being overcooled or overheated, thereby affecting the preservation of food, and can also improve cooling efficiency.

[0131] In the two air outlets 220 in the same accommodating area, when the two spoilers 300 open the air outlets 220 , the directions of the two spoilers 300 are opposite.

[0132] Each air outlet 220 is equipped with a spoiler 300. When the spoilers 300 of the two air outlets 220 are opened at the same time, they are directed in opposite directions. In this way, one spoiler 300 guides the cold air to the left, and the other spoiler 300 guides the cold air to the right. This design can enable the cold air to circulate in the storage area, avoiding blowing directly onto the food, thereby reducing the drying of the food. By optimizing the cold air distribution through the above setting, a constant low temperature can be maintained in each storage area, thereby improving the preservation effect of the food.

[0133] In some possible implementations, the first end of the spoiler 300 is rotatably disposed on the wind guide structure 200 , and the second end of the spoiler 300 is closer to the second end of the wind guide channel 210 relative to the first end of the spoiler 300 .

[0134] Through the arrangement of the above embodiment, the spoiler 300 can adjust its angle as needed to change the direction and intensity of the airflow; the arrangement of the second end of the above spoiler 300 can ensure that the spoiler 300 can effectively guide and disperse the airflow, avoiding direct blowing onto the food, while ensuring that the cold air is blown from the spoiler into the accommodation area.

[0135] The box body has a left side wall and a right side wall arranged opposite to each other in the horizontal direction; in the two air outlets 220 in the same accommodating area, the first end of one spoiler 300 is close to the left side wall, and the first end of the other spoiler 300 is close to the right side wall.

[0136] Through the configuration of the above embodiment, the airflow can be more evenly distributed in the storage area, avoiding excessive airflow in local areas, avoiding overcooling or overheating in local areas, ensuring a more uniform temperature in the entire storage area, and helping to keep the food fresh.

[0141] The refrigerator also includes an air guide structure 200, which can form multiple air guide channels 210. The first end of the air guide channel 210 can be connected to the air outlet 220 of the fan 100, and the second end of the air guide channel 210 can extend toward the outside of the air guide structure 200.

The plurality of air outlets 220 may be provided corresponding to the plurality of air guide channels 210 .
