Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically to a damper assembly, an air duct assembly, and a refrigerator. Background Technology

[0002] As people's living standards improve, refrigerators, as food storage devices, are used to store an increasing variety of foods. Ordinary refrigerators typically only have a 2-8℃ temperature zone in the refrigeration compartment. The drawers and shelves are cooled via airflow from the refrigeration duct, resulting in a relatively uniform temperature across all zones without adjustment. However, current needs include 4℃ refrigeration, around 0℃ ice temperatures, and a -5℃ slush storage area. Additionally, the dry goods section requires independent temperature and humidity control, and the tropical fruit section needs both cooling and heating up to 12℃, all requiring independent temperature control. Modifying an ordinary refrigerator to have multiple zones would require adding air vents to each zone, which takes up a lot of space, complicates wiring, and increases the size of the controller due to the increased interfaces, thus reducing the refrigerator's volume.

[0003] Because existing refrigerators have technical problems such as failing to meet the different temperature control requirements of different functional areas, resulting in low temperature control accuracy, this utility model studies and designs a damper assembly, an air duct assembly, and a refrigerator. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defect of existing refrigerators that cannot meet the different temperature control requirements of different functional areas, resulting in low temperature control accuracy, and thus provide a damper assembly, an air duct assembly, and a refrigerator.

[0005] To address the above problems, this utility model provides a damper assembly, comprising: A first damper and a second damper are provided. The first damper is provided with at least one first air outlet, and the second damper is fixed and provided with at least two second air outlets. Different second air outlets correspond to different temperature functional zones. The first damper and the second damper can move relative to each other, so that at least one first air outlet on the first damper and at least one second air outlet on the second damper are connected to each other, forming a multi-functional damper for different temperature functional zones. The first damper moves in a translational manner.

[0006] In some implementations... The first air outlet includes a first air outlet one and a first air outlet two, and the second air outlet includes a second air outlet one, a second air outlet two and a second air outlet three, with the second air outlet two located between the second air outlet one and the second air outlet three; In the initial state, the first damper is located on the side of the second air vent one that is away from the second air vent three. At this time, the first air vent one is closer to the second air vent one relative to the first air vent two. In the operating state, the first damper moves toward the second air vent one and communicates with at least one of the second air vent one, the second air vent two and the second air vent three through the first air vent one and the first air vent two, respectively, to form different air outlet modes.

[0007] In some implementations... When the first air vent is connected to the second air vent, both the second air vent and the second air vent are closed, forming the first air outlet mode. When the first air vent is connected to the second air vent, both the second air vent and the second air vent are closed, forming a second air outlet mode. When the first air vent is connected to the second air vent, both the second air vent and the second air vent are closed, forming the third air outlet mode. When the first air vent is connected to the second air vent, and the first air vent is connected to the second air vent, the second air vent is closed, forming the fourth air outlet mode. When the first air outlet 2 is simultaneously connected to the second air outlet 1 and the second air outlet 2, the second air outlet 3 is closed, forming the fifth air outlet mode; When the first air outlet 2 is simultaneously connected to the second air outlet 2 and the second air outlet 3, the second air outlet 1 is closed, forming the sixth air outlet mode.

[0008] In some implementations... A damper motor and a damper gear are provided on the side of the second damper plate facing the first damper plate. A damper rack is provided on the first damper plate. The damper rack meshes with the damper gear to drive the first damper plate to move horizontally, thereby achieving relative communication between the first air outlet and the second air outlet and completing different air outlet modes.

[0009] This utility model also provides an air duct assembly, which includes the aforementioned damper assembly; An air inlet duct is provided on one side of the first damper baffle, and the air inlet duct can communicate with the first air outlet on the first damper baffle to allow air to enter the first air outlet; An air outlet duct is provided on the side of the second damper away from the first damper, and the air outlet duct can communicate with the second air outlet on the second damper to guide the air outlet.

[0010] In some implementations... When the second air outlet includes second air outlet one, second air outlet two, and second air outlet three: the air outlet duct includes first air outlet duct, second air outlet duct, and third air outlet duct, the first air outlet duct is connected to second air outlet one, the second air outlet duct is connected to second air outlet two, and the third air outlet duct is connected to second air outlet three.

[0011] In some implementations... The refrigerator also includes a housing, on which the air inlet duct and the air outlet duct are formed. The housing also has an upper refrigeration air outlet and a lower refrigeration air outlet, both of which are connected to the second air outlet. The upper refrigeration air outlet is located above the lower refrigeration air outlet, and both are used to supply air to the refrigerator compartment. The housing also has an upper air outlet and a lower air outlet, with the upper air outlet connected to the second air outlet and the lower air outlet connected to the second air outlet. The housing also has a return air inlet. Furthermore, the refrigerator includes a heat exchanger, which is disposed within the air inlet duct, and the return air inlet is positioned opposite the heat exchanger.

[0012] In some implementations... It also includes a fan and a heat exchanger, both of which are disposed in the air inlet duct. The air outlet of the fan faces the first air outlet of the first damper baffle, and the air inlet of the fan faces the heat exchanger, so that the gas after heat exchange by the heat exchanger is drawn into the fan and blown out from the air outlet of the fan into the damper assembly. The damper assembly includes the first damper baffle and the second damper baffle.

[0013] In some implementations... The fan is a centrifugal fan, including at least two air outlets. There are also at least two damper assemblies, and the damper assemblies are arranged opposite to the air outlets of the fan. There are also at least two air outlet ducts, and the air outlet ducts are arranged corresponding to the second damper baffles of the damper assemblies.

[0014] This utility model also provides a refrigerator, which includes the aforementioned air duct assembly.

[0015] The damper assembly, air duct assembly, and refrigerator provided by this utility model have the following beneficial effects: 1. This utility model, through the structure of setting first and second air dampers, wherein the first air damper can move in a translational manner relative to the second air damper, and the second air damper is provided with at least two second air vents, which can supply air to different functional areas, and the first air damper is provided with at least one first air vent, which can be controlled by the translational movement of the first air damper to whether the first air vent is relatively connected to the second air vent, and to which or several of the second air vents it is relatively connected to. This achieves the effect of independent temperature control and adjustment for different functional areas of the refrigerator. Moreover, the translational movement, compared with other movement methods in the prior art (such as rotation), has a faster response speed, more sensitive control, and lower cost. The refrigeration compartment can be set with multiple independently controllable functional temperature zones to achieve temperature regulation and temperature uniformity control, and the placement of the air dampers is more flexible. This utility model can effectively solve the problem that the refrigerators in the prior art cannot meet the different temperature adjustment needs of different functional areas, resulting in low temperature control accuracy.

[0016] 2. Furthermore, this utility model, through the structure of a multi-functional damper combined with a refrigerated air duct, can introduce airflow through the air inlet duct and exchange heat with the heat exchanger, and deliver the air to different functional areas through the damper assembly via a fan, thereby achieving precise temperature control of different areas. Through the unique combination structure of the damper assembly and the air duct structure, it is possible to achieve independent temperature control of different functional areas with a small footprint in the refrigerator, thus improving the accuracy of temperature control.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0022] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

[0024] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0025] like Figure 1-10 As shown, this utility model provides a damper assembly, which includes: A first damper 1 and a second damper 2 are provided. The first damper 1 is provided with at least one first air outlet 3. The second damper 2 is fixed and is provided with at least two second air outlets 4. Different second air outlets 4 correspond to different temperature functional zones. The first damper 1 and the second damper 2 can move relative to each other, so that at least one first air outlet 3 on the first damper 1 and at least one second air outlet 4 on the second damper 2 are relatively connected to each other, forming damper air outlets for different temperature functional zones. The first damper 1 moves in a translational manner.

[0026] This invention features a structure with first and second damper baffles, where the first damper baffle can move in a translational manner relative to the second damper baffle. The second damper baffle has at least two second air vents, which can supply air to different functional zones. The first damper baffle has at least one first air vent, and the translational movement of the first damper baffle controls whether the first air vent connects to a second air vent, and which specific second air vents it connects to. This achieves independent temperature control for different functional zones of the refrigerator. Furthermore, the translational movement, compared to other movement methods in the prior art (such as rotation), offers faster response, more sensitive control, and lower cost. The refrigerator compartment can be set with multiple independently controllable functional temperature zones, achieving temperature regulation and temperature uniformity control, and the damper placement is more flexible. This invention effectively solves the problem in existing refrigerators that cannot meet the different temperature control needs of different functional zones, resulting in low temperature control accuracy.

[0027] In some implementations... The first air vent 3 includes a first air vent 5 and a second air vent 6, and the second air vent 4 includes a second air vent 7, a second air vent 8 and a third air vent 9, with the second air vent 8 located between the second air vent 7 and the second air vent 9. In the initial state, the first damper 1 is located on the side of the second air vent 7 away from the second air vent 9. At this time, the first air vent 5 is closer to the second air vent 7 relative to the first air vent 6. In the operating state, the first damper 1 moves toward the second air vent 7 and communicates with at least one of the second air vent 7, the second air vent 8, and the second air vent 9 through the first air vent 5 and the first air vent 6, respectively, to form different air outlet modes.

[0028] This is a preferred structural form of the first and second air inlets of this utility model, which can form a preferred structural form in which two air inlets on the first damper baffle cooperate with three air inlets on the second damper baffle, such as... Figure 3 As shown, this is the initial position of the first damper, which is completely located to the right of the three air vents of the second damper. Then, during operation, the motor controls the first damper to move towards the second air vent, thereby connecting the first air vents one and two to the second air vents one, two and three, respectively. This achieves the purpose of supplying air to different air outlet areas, realizing independent temperature control and improving temperature control accuracy.

[0029] In some implementations... When the first air vent 5 is connected to the second air vent 7, the second air vent 8 and the second air vent 9 are both closed, forming the first air outlet mode. When the first air vent 5 is connected to the second air vent 8, the second air vent 7 and the second air vent 9 are both closed, forming the second air outlet mode. When the first air vent 5 is connected to the second air vent 9, the second air vent 7 and the second air vent 8 are both closed, forming the third air outlet mode. When the first air vent 6 is connected to the second air vent 7, the second air vent 8 and the second air vent 9 are closed, forming the fourth air outlet mode; When the first air vent 6 is simultaneously connected to the second air vent 7 and the second air vent 8, the second air vent 9 is closed, forming the fifth air outlet mode; When the first air vent 6 is simultaneously connected to the second air vent 8 and the second air vent 9, the second air vent 7 is closed, forming the sixth air outlet mode.

[0030] This describes the multiple air outlet modes that can be formed during the movement of the first damper baffle of this utility model. The first air outlet mode is... Figure 7 As shown in the image above, the second air outlet mode is Figure 6 As shown in the image above, the third air outlet mode is Figure 6 As shown in the middle image, the fourth air outlet mode is Figure 7 As shown in the image above, the fifth air outlet mode is Figure 7 As shown in the image below, the sixth air outlet mode is not shown in the image, and there is also... Figure 5 The three operating states (including fully open), and Figure 6 The image below shows the fully closed operating state, which users can select. It can provide a variety of air outlet modes for different needs, meet various cooling requirements, and improve the temperature control accuracy of the refrigerator's multi-functional areas.

[0031] Initially, the inner damper is in the rightmost position, and its left end face is to the right of the rightmost opening of the outer damper, as shown below. Figure 3 At position A, the damper is in a state where all three openings are open, such as... Figure 5 First view location; When the inner baffle of the damper moves along Figure 3 The arrow indicates that when moving from position A to position B, the inner damper blocks the rightmost opening of the outer damper (the refrigerated shelf air outlet), forming... Figure 5 The second view position is where the refrigerated air vent on the shelf is closed, and the other two vents are open; Similarly, when the inner baffle of the damper moves along Figure 3 The arrow indicates the position when moving from B to C. Figure 5 In the third view, only the bottom air vent is open; When the inner baffle of the damper moves along Figure 3 As indicated by the arrow, when moving from position C to position D, the left opening of the inner damper and the middle opening of the outer damper align and connect, forming a single open middle air outlet. The other two openings of the outer damper are blocked and closed by the inner damper. Figure 6 As shown in the first view; When the inner damper is in Figure 4 At position E, we can obtain Figure 7 The open / closed state of the first view.

[0032] When the inner damper continues to move to position F, it can also obtain Figure 7 The second view shows the opening and closing status of the air vent.

[0033] In some implementations... A damper motor 10 and a damper gear 11 are provided on the side of the second damper baffle 2 facing the first damper baffle 1. A damper rack 12 is provided on the first damper baffle 1. The damper rack 12 meshes with the damper gear 11 to drive the first damper baffle 1 to move horizontally, thereby realizing the relative connection between the first air outlet 3 and the second air outlet 4 and completing different air outlet modes.

[0034] like Figure 1-4 As shown, this utility model, through the aforementioned damper motor and damper gear + damper rack drive transmission structure, can effectively drive the first damper baffle to perform translational motion, thereby realizing a state in which one or more first air outlets and which one or more second air outlets are relatively connected, and then controlling the targeted airflow cooling according to the needs of multiple areas inside the refrigerator, improving the effect of independent temperature control and improving temperature control accuracy.

[0035] Figure 1The diagram shows a schematic of the multifunctional damper assembly of this utility model. A stepper motor (damper motor 10) drives the damper gear 11, which in turn drives the damper rack 12 and the inner damper baffle (first damper baffle 1) to reciprocate. Two first air vents are provided on the inner damper baffle. Figure 2 The outer baffle of the damper (second damper baffle 2) is equipped with three second seals, which correspond to the three air outlet ducts on the refrigeration side. Figure 9 ). Figure 2 This is an exploded view of the multi-functional damper. The rear cover and the outer baffle of the damper are fastened together with screws.

[0036] This utility model also provides an air duct assembly, which includes the aforementioned damper assembly; An air inlet duct 13 is provided on one side of the first damper baffle 1. The air inlet duct 13 can communicate with the first air outlet 3 on the first damper baffle 1 to allow air to enter the first air outlet 3. An air outlet duct 14 is provided on the side of the second damper 2 away from the first damper 1. The air outlet duct 14 can communicate with the second air outlet 4 on the second damper 2 so as to guide the air outlet 4.

[0037] This utility model further utilizes a multi-functional damper combined with a refrigerated air duct structure to introduce airflow through the air inlet duct and exchange heat with the heat exchanger. The fan then delivers the airflow through the damper assembly to different functional areas, achieving precise temperature control for different areas. Through the unique combination of the damper assembly and the air duct structure, independent temperature control of different functional areas can be achieved with a small footprint in the refrigerator, improving temperature control accuracy.

[0038] In some implementations... When the second air outlet 4 includes the second air outlet 7, the second air outlet 8, and the third air outlet 9: the air outlet duct 14 includes the first air outlet duct 15, the second air outlet duct 16, and the third air outlet duct 17. The first air outlet duct 15 is connected to the second air outlet 7, the second air outlet duct 16 is connected to the second air outlet 8, and the third air outlet duct 17 is connected to the second air outlet 9.

[0039] This invention, through the preferred structure of the aforementioned air outlet duct, can form at least three air outlet duct structures, and these three air outlet ducts are respectively connected to three second air vents. Thus, by moving the first air damper of the air damper assembly, it is possible to control which one or more of the three second air vents will emit air, thereby controlling which one or more of the three air outlet ducts will emit air. This enables targeted airflow cooling based on the needs of multiple areas inside the refrigerator, improving the effect of independent temperature control and increasing temperature control accuracy.

[0040] In some implementations... The refrigerator also includes a housing 18, on which the air inlet duct 13 and the air outlet duct 14 are provided. The housing 18 also has an upper refrigeration air outlet 19 and a lower refrigeration air outlet 20, both of which are connected to the second air outlet 7. The upper refrigeration air outlet 19 is located above the lower refrigeration air outlet 20, and both are used to supply air to the refrigerator compartment. The housing 18 also has an upper air outlet 25 and a lower air outlet 21, with the upper air outlet 25 connected to the second air outlet 8 and the lower air outlet 21 connected to the second air outlet 9. The housing 18 also has a return air inlet 22. Furthermore, the refrigerator includes a heat exchanger 23, which is disposed within the air inlet duct 13, and the return air inlet 22 is disposed opposite to the heat exchanger 23.

[0041] This is a further structural improvement of the air duct assembly of this utility model. Specifically, the aforementioned air inlet and outlet ducts are opened on the housing, and upper and lower air outlets for refrigeration are opened on the housing, located at the end connected to the first air outlet duct. This allows for separate air supply to the upper and lower parts of the refrigeration area. The upper and lower air outlets on the housing can supply air to the upper and lower areas separately, achieving the purpose and effect of independent temperature control of the area. Furthermore, air can be introduced into the interior of the air duct assembly through the return air inlet, thereby exchanging heat with the heat exchanger in the air inlet duct. The damper assembly controls the airflow direction, achieving the effect of independent temperature control of multiple functional areas, further improving the temperature control accuracy.

[0042] In some implementations... It also includes a fan 24 and a heat exchanger 23, both of which are disposed in the air inlet duct 13. The air outlet of the fan 24 faces the first air outlet 3 of the first damper 1, and the air inlet of the fan 24 faces the heat exchanger 23, so that the gas after heat exchange by the heat exchanger 23 is drawn into the fan 24 and blown out from the air outlet of the fan 24 into the damper assembly 28. The damper assembly 28 includes the first damper 1 and the second damper 2.

[0043] This invention also utilizes the aforementioned fan and heat exchanger structure to drive the airflow entering the duct assembly from the return air inlet to first pass through the heat exchanger for heat exchange, be cooled to form cold air, and then be blown towards the damper assembly by the fan. Through the movement control of the damper baffle, it is possible to blow air from different second air inlets to different outlet ducts, thereby reaching different functional areas and providing them with cold air for cooling. This allows for temperature control of different functional areas according to requirements, improving temperature control accuracy.

[0044] In some implementations... The fan 24 is a centrifugal fan, including at least two air outlets. There are also at least two damper assemblies, and the damper assemblies 28 are arranged opposite to the air outlets of the fan 24. There are also at least two air outlet ducts 14, and the air outlet ducts 14 are arranged corresponding to the second damper baffles 2 of the damper assembly 28.

[0045] Furthermore, this utility model further utilizes the aforementioned centrifugal fan, which has at least two air outlets, and can be equipped with damper components and air outlet ducts on both sides respectively. This enables independent temperature control of more functional areas, further meeting the independent temperature requirements of more functions inside the refrigerator, improving temperature control accuracy, and better satisfying user needs.

[0046] This utility model also provides a refrigerator, which includes the aforementioned air duct assembly.

[0047] Figure 8 This is a diagram showing a multi-functional damper placed in a refrigerated air duct. The damper is positioned in the correct orientation. Figure 5 In the second view, the refrigerated air vents in the shelf area are closed, and the centrifugal fan's airflow only exits through the middle and bottom vents, entering the corresponding drawers for cooling. A multi-functional damper is installed on each side of the refrigerated air duct. This results in... Figure 9 The overall refrigerated air duct shown has its upper glass shelf area cooled by four air outlets on the upper left and right sides. The airflow from these four outlets is controlled by the refrigerated air outlets of a multi-functional air damper. Figure 7 The first view shows the current state. The four air vents at the bottom correspond to four independent drawers, allowing for individual control from both the left and right sides. Figure 10 This is a schematic diagram of the back of the refrigeration air duct.

[0048] When the refrigerator's cooling duct is installed in the refrigerator compartment, temperature sensors are placed on both the left and right sides. When different amounts of food are placed on the left and right sides—for example, if more food is placed on the left shelf—the temperature sensors will detect a higher temperature and extend the opening time and adjust the opening position of the air vent on the left shelf to its maximum. At this time, the air vent position is as follows: Figure 7 View 1.

[0049] If the left side, upper left drawer, and lower left drawer of the refrigerated shelf are all filled with a large amount of food, resulting in a heavy load, and the temperature sensor detects a high temperature, then all three vents will open simultaneously, as shown in the diagram. Figure 5 The first view achieves a rapid cooling effect.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
