The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0030] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0031] Currently, a refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a household appliance that keeps food or other items at a constant low temperature.

[0032] Based on their cooling methods, refrigerators are divided into forced air circulation refrigerators and natural convection refrigerators. Forced air circulation refrigerators, also known as frost-free refrigerators, have a fan that forces airflow within the refrigerator, resulting in uniform temperature, rapid cooling, and ease of use. Natural convection refrigerators, also known as direct-cooling refrigerators, have a freezer compartment directly surrounded by an evaporator, or one evaporator inside the freezer compartment and another evaporator above the refrigerator compartment. The evaporator directly absorbs heat for cooling. These refrigerators have a relatively simple structure and low power consumption, but their temperature control is slightly worse, and they are less convenient to use. Currently, frost-free refrigerators are more common.

[0033] The airflow and temperature distribution within the refrigerator compartment of a frost-free refrigerator significantly impacts the food stored there. However, traditional frost-free refrigerators' air duct structures cannot accurately identify high-temperature areas within the storage zone for precise airflow, resulting in low cooling rates and poor temperature uniformity across storage areas. In related technologies, to achieve precise airflow to the storage zone, solutions have emerged that control the flow rate of cold air output from the air outlets in the air duct by adjusting dampers. However, electric dampers are costly and the control process is complex.

[0034] Therefore, this invention provides an air-cooled refrigerator 1000 to solve the above-mentioned technical problems. The following is a detailed description... Figure 1 to Figure 3 The technical solution of the present invention will be described in detail below.

[0035] In some implementations, refer to Figure 1 and Figure 3As shown, the air-cooled refrigerator 1000 includes: a shell, with a central beam 130 inside, dividing the internal space of the shell into a first space 110 and a second space 120. The central beam 130 has a vertically penetrating air duct 100a inside. The side walls of the first space 110 and the second space 120 are provided with air outlets connected to the air duct 100a; a fan 200, located at the lower part of the air duct 100a, for blowing cold air 201 upward along the air duct 100a; and an air guide assembly, including a first drive mechanism, a second drive mechanism, and an air guide plate 100. The air guide plate 100 can move up and down within the air duct 100a under the drive of the first drive mechanism to stop at the air outlets of the first space 110 and the second space 120, and can swing at a certain angle under the drive of the second drive mechanism to guide the cold air 201 into the storage area.

[0036] It should be noted that, Figure 3 The air-cooled refrigerator 1000 shown is a double-door refrigerator. The air-cooled refrigerator 1000 of this embodiment is not limited to double-door refrigerators, but also includes refrigerators with other types of doors.

[0037] It should also be noted that the oscillation of the air guide plate in the embodiment of the present invention can be understood as rotating along a rotation axis with a certain amplitude. The rotation axis can be one side edge in its length direction. This side edge does not move relative to the other side edge, and the other side edge moves to achieve oscillation.

[0038] In a traditional air-cooled refrigerator 1000, the air duct 100a structure is located inside the side wall of the refrigerator shell, and the fan 200 is located at the lower part of the air duct 100a structure. Under the action of the fan 200, cold air 201 is blown upward and delivered to each storage area through the air outlet. As the cold air 201 blows upward along the air duct 100a, it is obstructed when it reaches the top. The cold air 201 tends to accumulate at the top of the air duct 100a and enters the storage area at the top, which can easily cause the temperature of the top storage area to be lower than that of the storage areas below.

[0039] In this embodiment of the invention, an air duct 100a is formed within the central beam 130. The fan 200 blows cold air 201 within the air duct 100a. The cold air 201 can enter the first space 110 or the second space 120 through the air outlet. The flow state of the cold air 201 within the air duct 100a can be changed by the air guide plate 100 of the air guide assembly. For example, the flow path of part of the cold air 201 can be changed by the air guide plate 100 and guided into the first space 110 or the second space 120.

[0040] The air-cooled refrigerator 1000 of this invention features an air duct 100a located inside the central beam 130, with air outlets connected to the air duct 100a on the side walls of the storage area. A first driving mechanism drives a guide plate 100 to the corresponding air outlet, and a second driving mechanism drives the guide plate 100 to swing at a certain angle to guide cold air 201 into the corresponding storage area. This design is simple in structure and easy to control, making it highly efficient and practical. In particular, because the air duct 100a is located inside the central beam 130, a single air duct 100a can cool both the first space 110 and the second space 120 on both sides of the central beam 130. Compared to the prior art where the air duct is located on the side wall, this simplifies the refrigerator structure. Furthermore, cooling of both spaces can be achieved simply by controlling the guide components within the air duct 100a, making the control method convenient.

[0041] It should be noted that the air guide plate 100 can have an airflow adjustment angle relative to the vertical direction, pointing towards the storage area. When the airflow adjustment angle changes, the airflow introduced by the air guide plate 100 changes. Therefore, the airflow of the cold air 201 introduced into the storage area can be adjusted by swinging the air guide plate 100 to change the airflow adjustment angle. In other words, when a storage area needs cooling, the air guide plate 100 can be swinged to better achieve cooling of that storage area.

[0042] The air-cooled refrigerator 1000 of the present invention has at least the above-mentioned beneficial effects.

[0043] In some embodiments, the interior of both the first space and the second space is defined to form at least two storage areas, with air outlets disposed on the sidewalls of each storage area.

[0044] In this way, the air duct can connect the storage areas of the first space and the second space.

[0045] It is understood that the first space 110 and the second space 120 are separated from the air duct 100a by walls. The first space 110 and the second space 120 are located on opposite sides of the air duct 100a. Air outlets are provided on the side walls of the first space 110 and the second space 120 near the air duct 100a. Cool air flowing within the air duct 100a can be guided by the air guide plate 100 through the air outlets to the corresponding storage areas, such as... Figure 3 As shown. Further, the air outlets on the sidewall of the first space 110 can be set at different heights than the air outlets on the sidewall of the second space 120. In some embodiments, the number of air outlets on the sidewall of the first space 110 can be equal to the number of air outlets on the sidewall of the second space 120, and the air outlets of both spaces can correspond one-to-one at the same height, facilitating the swinging of the air guide plate 100 to introduce cool air into either the first space 110 or the second space 120, such as... Figure 3As shown. Of course, in more embodiments, the air outlets on the sidewall of the first space 110 may be partially at the same height as the air outlets on the sidewall of the second space 120, or none of the air outlets on the sidewall of the first space 110 may be at the same height as the air outlets on the sidewall of the second space 120. Additionally, in some embodiments, the number of air outlets on the sidewall of the first space 110 may not be equal to the number of air outlets on the sidewall of the second space 120. It should be noted that the air guide plate of this embodiment can guide sufficient cold air to the target area based on the distribution position and number of the air outlets on the sidewalls of the first space 110 and the second space 120.

[0046] In some embodiments, the air guide plate 100 is positioned at the air outlet of the first space 110 and swings at a first angle to guide the cold air 201 into the first space 110; the air guide plate 100 is positioned at the air outlet of the second space 120 and swings at a second angle to guide the cold air into the corresponding storage area.

[0047] In this way, sufficient cold air can be introduced to cool the first space 110 and the second space 120.

[0048] Specifically, when the first space 110 requires cooling, the air guide plate 100 is driven to move to the corresponding air outlet of the first space 110. The air guide plate 100 can then guide sufficient cold air 201 into the first space 110 through the air outlet. Furthermore, the air guide plate 100 can swing at a first angle (i.e., adjust the airflow adjustment angle of the air guide plate 100 relative to the first space 110) to introduce the required amount of cold air 201 into the first space 110. For example, before rotation, the airflow adjustment angle of the air guide plate 100 towards the first space 110 is 135 degrees. After rotation at the first angle, the airflow adjustment angle of the air guide plate 100 towards the first space 110 is 105 degrees. That is, after swinging, the air guide plate 100 is closer to the horizontal direction, which can reflect more cold air 201 into the first space 110. It should be noted that the air volume adjustment angle listed in this embodiment is only for the purpose of understanding and is not intended as a specific limitation. In other embodiments, the air guide plate 100 swings to meet the requirement of introducing more air volume.

[0049] When the second space 120 requires cooling, the air guide plate 100 is driven to move to the corresponding air outlet of the second space 120. The air guide plate 100 can then guide sufficient cool air 201 into the second space 120 through the air outlet. Furthermore, the air guide plate 100 can swing at a second angle (i.e., adjust the airflow adjustment angle of the air guide plate 100 relative to the second space 120) to introduce the required amount of cool air 201 into the second space 120. For example, before rotation, the airflow adjustment angle of the air guide plate 100 towards the second space 120 is 138 degrees. After rotation at the second angle, the airflow adjustment angle of the air guide plate 100 towards the second space 120 is 108 degrees. That is, after swinging, the air guide plate 100 is closer to a horizontal direction, allowing more cool air 201 to be reflected into the second space 120. It should be noted that the air volume adjustment angle listed in this embodiment is only for the purpose of understanding and is not intended as a specific limitation. In other embodiments, the air guide plate 100 swings as long as it can meet the requirement of introducing sufficient air volume.

[0050] In some embodiments, the air outlets of the first space 110 and the second space 120 are located at the same height. When the air guide plate 100 swings to a horizontal state under the drive of the second drive mechanism, it can simultaneously introduce cold air 201 into the first space 110 and the second space 120.

[0051] In this way, the air guide plate 100 can simultaneously introduce the required amount of cold air 201 into the first space 110 and the second space 120.

[0052] It is conceivable that the relative positions of the air outlets of the first space 110 and the second space 120 can affect the arrangement of the air guide plate 100 and its air guiding effect. In this embodiment, referring to... Figure 3 As shown, when the air outlets of the two spaces are opposite each other (i.e., at the same height), the air guide plate 100 can simultaneously introduce cold air 201 into the first space 110 and the second space 120 when the oscillation angles are different, and the introduced air volume can be the same or different. For example, when the air guide plate 100 oscillates to a horizontal state under the drive of the second drive mechanism, the air volume of cold air 201 introduced into the first space 110 and the second space 120 can be the same. Optionally, considering that there may be a gap between the air guide plate 100 and the side wall of the air duct 100a, and that the gaps on both sides may have different areas, the air volume introduced into the first space 110 and the second space 120 can be different when the air guide plate 100 is in a horizontal state. The air guide plate 100 of this embodiment can oscillate at different angles according to the positional relationship between the air outlets of the first space 110 and the second space 120 to simultaneously introduce the required air volume of cold air 201 into both the first space 110 and the second space 120.

[0053] Furthermore, the air guide plate 100 of the present invention can be swung at different angles to simultaneously introduce the required amount of cold air 201 into the first space 110 and the second space 120 based on the positional relationship between the air outlet of the first space 110 and the air outlet of the second space 120, and in combination with the gap formed between the air guide plate 100 and the side wall of the air duct 100a.

[0054] Furthermore, the air guide plate 100 of the present invention can simultaneously introduce the required amount of cold air 201 into the first space 110 and the second space 120 by swinging at different angles, based on the positional relationship between the air outlet of the first space 110 and the air outlet of the second space 120, the gap formed between the air guide plate 100 and the side wall of the air duct 100a, and in combination with the shape and posture of the air guide plate 100.

[0055] In some embodiments (not shown in the figures), the first drive mechanism includes a motor and a conveyor belt, with the air guide plate 100 mounted on the conveyor belt. The motor can drive the conveyor belt to move the air guide plate up and down.

[0056] In this way, the air guide plate 100 can be driven to move to the target position.

[0057] Specifically, when a storage area needs cooling, the air outlet corresponding to that storage area can be considered the target location. The air guide plate 100 is mounted on a conveyor belt, and a motor drives the conveyor belt to move the air guide plate 100. It can be understood that the air guide plate 100 is driven to a position where it can guide air into the storage area. For example, when a storage area in the first space 110 needs more cold air 201, the air guide plate 100 is driven to the air outlet corresponding to that storage area, allowing sufficient cold air 201 to be introduced to cool the storage area. The air guide plate 100 can be fixedly mounted on the conveyor belt by adhesive, screws, or snap-fit, and the conveyor belt can be driven by a motor configured as a unidirectional or bidirectional motor. The motor can change its power to adjust the moving distance of the air guide plate 100; optionally, a bidirectional motor can change its direction of rotation to change the moving direction of the air guide plate 100.

[0058] Reference Figure 2 As shown, in some embodiments, the first drive mechanism includes a motor and a screw 104, and the air guide plate 100 includes a connecting part 101 and a blade 102. The connecting part 101 is provided with a thread that mates with the screw 104. The motor can drive the screw 104 to rotate, thereby driving the air guide plate 100 to move up and down.

[0059] In this way, the air guide plate 100 can be driven to move to the target position.

[0060] Specifically, when a storage area needs cooling, the air outlet corresponding to that storage area can be considered the target location. The screw 104 is configured to allow the air guide plate 100 to move along the flow path of the cold air 201. In this embodiment, the extension direction of the screw 104 is the same as the extension direction of the flow path of the cold air 201. The motor drives the screw 104 to rotate, and the air guide plate 100 can move on the screw 104 and reach the target location, thus introducing sufficient cold air 201 to cool the storage area. The connecting part 101 can be specifically selected according to actual needs, such as being square or other shapes. The connecting part 101 only needs to have threads that mate with the screw 104 and be able to drive the air guide plate 100 to move up and down under the rotation of the screw 104. The connecting part 101 is configured as a cylindrical structure with internal threads inside. This configuration allows the connecting part 101 to better support and cooperate with the screw 104, thereby moving up and down along the screw 104 more smoothly. It should be noted that, in this embodiment, the air guide plate 100 swings to adjust the air volume, which is configured to be achieved by the swing of the vane 102. That is, the vane 102 is part of the air guide plate 100, and the swing of the vane 102 can realize the air guide plate 100 to adjust the air volume.

[0061] In some alternative embodiments, the motor may be selected as a bidirectional motor. Through the cooperation of the connecting part 101 and the screw 104, when the bidirectional motor rotates forward, it drives the air guide plate 100 to move upward, and when the bidirectional motor rotates in reverse, it drives the air guide plate 100 to move downward.

[0062] In some implementations, the motor is selected as a unidirectional motor, and the screw 104 is selected as a reciprocating screw 104 (e.g., Figure 2 (As shown). It can be understood that this allows the air guide plate 100 to reciprocate along the screw 104. Specifically, by rotating the motor in the forward or reverse direction, the connecting part 101 can move upward or downward along the screw 104; that is, the air guide plate 100 connected to the connecting part 101 can move upward or downward. In this embodiment, a unidirectional motor is selected, and a reciprocating screw 104 is selected. By cooperating with the unidirectional motor and the reciprocating screw 104, the unidirectional rotation of the motor can drive the air guide plate 100 to move up and down, thereby simplifying the structure of the drive mechanism and reducing the production cost of the air-cooled refrigerator 1000.

[0063] In some embodiments, the connecting part 101 is configured as a cylindrical structure with internal threads inside. This allows the connecting part 101 to move by rotating the screw 104.

[0064] Specifically, the connecting part 101 has a cylindrical structure, meaning that a through hole is formed inside the connecting part 101 for housing the screw 104. The through hole is adapted to the outer peripheral surface of the screw 104, and the inner wall surface of the through hole is provided with internal threads. The screw 104 rotates, allowing the connecting part 101 to move along the screw 104. It can be understood that the outer peripheral surface of the screw 104 is cylindrical, and the cylindrical shape of the connecting part 101 can adapt to the screw 104. However, this design is not limited to this; in other embodiments, the connecting part 101 can also be configured with other shapes, as long as it can satisfy the requirement that the connecting part 101 moves according to the rotation of the screw 104.

[0065] Understandably, the airfoil 102 is a structure that uses the pressure difference of the fluid passing above and below the part to generate lift.

[0066] In some implementations, such as Figure 2 As shown, the first drive mechanism also includes a guide rod 103 arranged parallel to the screw 104. The guide rod 103 has a guide groove on one side facing the screw 104. One end of the wing 102 is connected to the connecting part 101, and the other end is movably disposed in the guide groove.

[0067] In this way, the movement of the air guide plate 100 can be made smoother. It can be understood that one end of the vane 102 is connected to the connecting part 101, and the other end can slide within the guide groove. It is conceivable that the guide groove on the guide rod 103 can provide guidance for the vane 102, making the sliding of the vane 102 more stable.

[0068] In some implementations, such as Figure 2 As shown, there are two guide rods 103, located on both sides of the screw 104, and two winglets 102, each winglet 102 being symmetrically arranged between the screw 104 and each guide rod 103. This allows the screw 104 to be centrally positioned, and also guides the winglets 102 on both sides of the screw 104.

[0069] Specifically, two vanes 102 are respectively disposed on both sides of the screw 104, which allows the screw 104 to be positioned in the middle of the airflow channel of the cold air 201. Two guide rods 103 are provided, located on both sides of the screw 104, and two vanes 102 are provided, each vane 102 being symmetrically disposed between the screw 104 and each guide rod 103. However, this design is not limited to this; in other optional embodiments, the number of guide rods 103 can also be set to other values.

[0070] It is particularly important to note that, in Figure 1 and Figure 2In the illustrated embodiment, the arrangement of components such as the air guide plate 100 and the screw 104 can be considered as an optional implementation of this invention, used to aid in understanding the technical solution of this application, and is merely an example, not a specific limitation. It is understood that in other embodiments, the air guide plate 100 and the screw 104 can be configured in other forms. In some embodiments, the air guide plate 100 includes a vane 102 connected to the connecting portion 101 of the screw 104 via a bridging portion. Furthermore, the vane 102 can rotate around the bridging portion, changing the direction of airflow. Even further, the vane 102 can have a hollowed-out clearance space in the middle, allowing it to avoid obstruction from the screw 104 when rotated to a certain extent.

[0071] Understandably, Figure 1 and Figure 2 In the embodiments shown, the arrangement of the air guide plate 100, screw 104, etc. can be considered as an optional implementation. Similarly, in other embodiments, the arrangement of the air guide plate 100, screw 104, etc. can be considered as another optional implementation. In these embodiments, the air guide plate 100, screw 104, etc. are designed to enable the wing 102 to rotate and / or flip.

[0072] In some implementations, a temperature sensor is provided in each storage area to detect the temperature within the storage area in real time. This allows for the detection and acquisition of temperature information within the storage area, enabling the control of the airflow rate of the cold air 201 introduced by the air guide plate 100 based on this temperature information.

[0073] Specifically, multiple temperature sensors are provided, each located in one of the storage areas to detect temperature. The number of temperature sensors in each storage area can vary as needed, and sensors can be positioned at different locations within the same storage area. This allows for the detection of temperature in each storage area and at different locations within each storage area. The temperature sensors detect the temperature at different locations and obtain corresponding temperature information. This temperature information can be used to adjust the airflow of the cold air introduced by the air guide plate 100. Optionally, the temperature information can also be used to adjust the blowing path of the cold air introduced by the air guide plate 100.

[0074] In some embodiments, the air-cooled refrigerator 1000 further includes a controller configured to: in response to a temperature in a storage area exceeding a preset value, drive mechanism drives air guide plate 100 to move and stop at the air outlet of the corresponding storage area; and second drive mechanism drives air guide plate 100 to swing at a certain angle to introduce cold air 201 into the storage area. Thus, the air guide plate 100 can be adjusted to introduce cold air 201 to cool the storage area based on temperature information.

[0075] It should be noted that in the air-cooled refrigerator 1000 of the present invention, the controller can adjust the air volume and air direction of the air guide plate 100 according to the temperature information of different storage areas, the temperature information of different locations in the storage areas, the relative positional relationship of the air outlets of the first space 110 and the second space 120, and the shape and posture of the air guide plate 100, thereby effectively realizing the cooling storage area.

[0076] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
