Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to an air-cooled refrigerator. Background Technology

[0002] With the improvement of people's living standards, refrigeration equipment such as refrigerators have become indispensable household appliances in people's daily lives. Among them, frost-free refrigerators are increasingly chosen by users due to their advantages such as fast cooling speed, good cooling effect and uniform temperature. Frost-free refrigerators generally include a cabinet, a door, and drawers installed inside the cabinet. When the door is opened, the drawers can be pulled out from the cabinet.

[0003] For frost-free refrigerators, there are gaps at the bottom of the drawers to allow circulating airflow to pass through. When circulating airflow flows through the bottom of the drawer, the airflow at the bottom of the drawer will impact the refrigerator door or the upward airflow from the lower shelf, creating vortices. This hinders the upward transfer of cold air and also has an adverse effect on the total circulating airflow. Because the operating conditions of frost-free refrigerators are relatively complex, the airflow in each shelf will change significantly during start-up, shutdown, stabilization, and defrosting phases. Therefore, it is impossible to control the airflow at the bottom of the drawer to maximize the upward transfer of airflow. At the same time, there will still be significant impact losses at the confluence of airflows. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect of poor upward transfer of cold air in the prior art of air-cooled refrigerators, and to provide an air-cooled refrigerator.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A frost-free refrigerator includes a cabinet, a first drawer, and a side door, characterized in that the frost-free refrigerator further includes an airflow guiding device, the airflow guiding device comprising:

[0007] A partition platform is provided inside the box and located at the bottom of the first drawer. A main airflow channel is formed between the partition platform and the bottom of the first drawer. An auxiliary airflow channel is formed on the side wall of the partition platform near the wall door.

[0008] A flow guide is provided on the partition platform along the length of the air-cooled refrigerator and extends vertically upward relative to the partition platform. The flow guide is offset from the first drawer in the width direction of the air-cooled refrigerator so as to guide the airflow in the main airflow channel and the auxiliary airflow channel upward from the side of the first drawer.

[0009] In this design, a flow guide device is installed at the bottom of the first drawer. The main airflow channel and the auxiliary airflow channel at the bottom of the first drawer are separated by the partition platform of the flow guide device. The main airflow channel is formed in the gap between the partition platform and the bottom of the first drawer, while the auxiliary airflow channel is formed on the side wall of the partition platform near the door. The airflow in the main airflow channel flows from the bottom of the first drawer to the position of the flow guide, while the airflow in the auxiliary airflow channel flows from the side wall of the partition platform to the position of the flow guide. The airflow is then guided vertically upward by the flow guide, allowing the airflow in both channels to be transmitted upward without impacting the bottom of the first drawer. This also avoids the impact between the airflow and the door, as well as the impact between the two airflows, greatly improving the upward transmission effect of cold air in the frost-free refrigerator.

[0010] Preferably, the partition platform includes:

[0011] The second drawer is located below the first drawer along the vertical direction of the air-cooled refrigerator, and the auxiliary airflow channel is formed on the side wall of the second drawer near the door.

[0012] A baffle is located at the top of the second drawer and forms the main airflow channel between it and the bottom of the first drawer. The airflow guide is disposed on the baffle.

[0013] In this solution, the multi-layer drawer design in the air-cooled refrigerator allows the second drawer, located below the first drawer, to form a partition platform together with a baffle. This further reduces the space occupied by the partition platform inside the air-cooled refrigerator without affecting its existing structure. At the same time, the baffle is placed on the top of the second drawer, and air guides are installed on the baffle to facilitate airflow.

[0014] Preferably, when no external force is applied, the guide extends vertically upward relative to the partition platform, and the top of the extension is located above the bottom of the first drawer. When the first drawer moves horizontally, it abuts against the guide and causes the guide to flip relative to the partition platform.

[0015] In this design, when the door of the frost-free refrigerator is closed, the first drawer and the air guide are misaligned, and the air guide is in a state without external force. At this time, the air guide extends vertically upward relative to the partition platform, and the top of the extension is located above the bottom of the first drawer to increase the upward extension size, thereby more effectively guiding the airflow upward inside the frost-free refrigerator. When the door of the frost-free refrigerator is opened, the first drawer comes into contact with the air guide during the horizontal outward pulling process, and drives the air guide to flip relative to the partition platform, so that the setting of the air guide does not affect the use of the first drawer.

[0016] Preferably, the flow guiding device further includes a base, which is disposed on the partition platform. The top of the base is provided with an arc-shaped groove, and the bottom of the flow guiding component is rotatably disposed in the arc-shaped groove, thereby causing the top of the flow guiding component to flip during rotation.

[0017] In this solution, by setting a base on the partition platform and setting an arc-shaped groove on the top of the base that matches the bottom of the guide component, the bottom of the guide component can rotate more easily within the arc-shaped groove, and the top of the guide component can be more easily flipped during rotation. Furthermore, this setting can also adjust the size and shape of the top of the guide component as needed, so that the center of gravity of the guide component is located at the bottom of the guide component, making it easier for the guide component to be in a vertically upward extending state relative to the partition platform when no external force is applied.

[0018] Preferably, the flow guiding device further includes a driving component, the baffle platform has an opening at the position corresponding to the base, the base is fitted into the opening, and the driving component is used to drive the base to move vertically within the opening.

[0019] In this design, when the first drawer is pulled out horizontally, the base can be moved vertically within the opening by the drive unit, so that the guide on the base can also move vertically relative to the partition platform, further avoiding interference between the guide and the first drawer. At the same time, the size of the guide extending vertically upward can be increased to improve its airflow guiding effect.

[0020] Preferably, the flow guiding device further includes a rotating shaft, which passes through the bottom of the flow guiding component along the length direction of the air-cooled refrigerator. Limiting grooves are correspondingly provided on two side walls of the cabinet along its length direction, and the two ends of the rotating shaft extending out of the flow guiding component are respectively accommodated in the corresponding limiting grooves.

[0021] In this solution, by means of this setting, during the process of the guide component flipping or lifting relative to the partition platform, the two ends of the guide component extending out of the rotating shaft are accommodated in the limiting groove located on the side wall of the box to limit the guide component, prevent the guide component from deviating from the predetermined position during the movement, and thus ensure the repeated and effective use of the guide device.

[0022] Preferably, the limiting grooves are all racetrack-shaped grooves, the straight segments of the racetrack-shaped grooves extend vertically on the side wall corresponding to the housing, and the sum of the vertically movable dimension of the base within the opening and the diameter of the rotating shaft is less than the length of the racetrack-shaped groove.

[0023] In this solution, the limiting groove is designed as a racetrack-shaped groove, with the straight section of the racetrack-shaped groove extending in the direction of its length. By setting its length dimension, both ends of the rotating shaft extending from the guide can move within the corresponding racetrack-shaped groove. This limits the guide while preventing it from detaching from the base during movement, thus improving the stability and reliability of the guide device.

[0024] Preferably, the flow guiding device further includes a limiting member, which is disposed on the surface of the partition platform where the opening is made and covers a portion of the opening. The bottom edge of the base is provided with a stepped portion, which can abut against the limiting member within the opening.

[0025] In this solution, by setting a limiting member on the surface of the opening of the partition platform and using the limiting member to abut against the step located at the bottom edge of the base, the size range of the base that can move vertically within the opening is limited as needed. At the same time, it also prevents the base from detaching from the partition platform when moving within the opening, thereby further improving the reliability of the flow guiding device.

[0026] Preferably, the base is provided with concave arc surfaces on both sides of the flow guide, and when the stepped portion abuts against the limiting member, the concave arc surface smoothly transitions with the upper surface of the corresponding limiting member.

[0027] In this design, in the area where the limiting member does not cover the opening, the base has a portion extending out of the opening during movement. This portion has concave arc surfaces on both sides of the guide member. When the step portion abuts against the limiting member, the concave arc surfaces on both sides of the guide member smoothly transition to the upper surface of the corresponding limiting member, allowing the airflow to move upward along the smoothly transitioning concave arc surfaces, further improving the airflow guiding effect of the guide device.

[0028] Preferably, the driving component includes an electromagnetic relay and a magnet, the electromagnetic relay and the magnet being respectively disposed on the bottom surface of the opening and the base, the electromagnetic relay being energized and acting on the magnet to drive the base to move within the opening.

[0029] In this solution, the interaction between the electromagnetic relay and the magnet when the relay is energized causes the base to move through the opening of the partition platform, thereby moving the guide component on the base. Compared with other driving methods, this method is simpler in structure and more convenient to operate.

[0030] Preferably, the flow guiding device further includes an elastic element disposed within the opening, with its two ends respectively abutting against the bottom surface of the opening and the base; when the electromagnetic relay is energized, it acts on the magnet to drive the base to move vertically downward within the opening, and during the movement, it squeezes the elastic element.

[0031] In this solution, by using the cooperation of the driving component and the elastic component, the base moves vertically downward in the opening when the electromagnetic relay in the driving component is energized, and the elastic component restores the base to its original position when it is de-energized. On the basis of the convenient movement of the base relative to the partition platform, its automatic reset capability is improved, so that the flow guiding device can be used repeatedly and effectively.

[0032] Preferably, the wall door of the air-cooled refrigerator is linked to the electromagnetic relay for control; wherein the electromagnetic relay is energized when the wall door is open.

[0033] In this solution, the base moves vertically downwards through the opening of the partition platform when the door of the frost-free refrigerator is opened. This causes the guide section on the base to also move vertically downwards, allowing the first drawer to be pulled out of the refrigerator body. This minimizes the impact of the guide device on the use of the first drawer and improves the user experience.

[0034] Preferably, when the electromagnetic relay is energized, it acts on the magnet to drive the base to move vertically upward within the opening; when the electromagnetic relay is de-energized, the base moves vertically downward within the opening using its own weight.

[0035] In this solution, by using this configuration, the cooperation between the driving component and the weight of the base allows the base to move vertically upward within the opening when the electromagnetic relay in the driving component is energized, and to move vertically downward within the opening when the relay is de-energized, thereby improving the ability of the base to move and reset, and enabling the flow guiding device to be used repeatedly and effectively.

[0036] Preferably, the wall door of the air-cooled refrigerator is linked to the electromagnetic relay for control; wherein the electromagnetic relay is de-energized when the wall door is open and energized when the wall door is closed.

[0037] In this solution, the electromagnetic relay is de-energized when the door of the frost-free refrigerator is opened, allowing the base to move vertically downwards within the opening using its own weight. This allows the first drawer to be pulled out of the refrigerator body, minimizing the impact of the guide device on the use of the first drawer and improving the user experience.

[0038] The positive and progressive effects of this invention are as follows:

[0039] By installing a guide device at the bottom of the first drawer of the frost-free refrigerator, the main airflow channel and the auxiliary airflow channel located at the bottom of the first drawer are separated by the partition platform of the guide device. The main airflow channel is formed in the gap between the partition platform and the bottom of the first drawer, and the auxiliary airflow channel is formed on the side wall of the partition platform near the door. The airflow in the main airflow channel flows from the bottom of the first drawer to the guide device, and the airflow in the auxiliary airflow channel flows from the side wall of the partition platform to the guide device. After being guided vertically upward by the guide device, the airflow in both channels can be transmitted upward without impacting the bottom of the first drawer. It also avoids the impact between the airflow and the door, as well as the impact between the two airflows, greatly improving the upward transmission effect of cold air in the frost-free refrigerator.

[0072] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0074] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0075] This embodiment provides a frost-free refrigerator, which includes a refrigerator compartment, a freezer compartment, and a compressor base plate. The refrigerator compartment and freezer compartment have similar structures. This embodiment only describes the refrigerator compartment as an example. It should be understood that by referring to the relevant description of the refrigerator compartment, the relevant structures and connections of the freezer compartment can be derived. These will not be described in detail here.

[0076] Figure 1 and Figure 2 These are schematic diagrams of the overall structure and the side view of the internal structure of the refrigerator compartment 1. The frost-free refrigerator compartment 1 includes a cabinet 10, a door 20, and a first drawer 30 for storing food, vegetables, beverages, etc. When the door 20 is closed, the first drawer 30 is housed inside the cabinet 10. When the door 20 is open, the first drawer 30 can be pulled out relative to the cabinet 10 along the width W of the refrigerator compartment 1, allowing the user to remove items from the first drawer 30 or place items inside the first drawer 30.

[0077] In addition, an airflow guiding device is installed inside the refrigerator compartment 1 to control the airflow at the bottom of the first drawer 30, so that the airflow is transmitted upward inside the refrigerator compartment 1, thereby affecting the entire interior space of the refrigerator compartment 1. Specifically, such as Figure 3 and Figure 4 As shown, the flow guiding device includes a baffle platform 41 and a flow guide 42. The baffle platform 41 is disposed inside the housing 10 and located at the bottom of the first drawer 30. A main airflow channel is formed between the baffle platform 41 and the bottom of the first drawer 30 (the flow path of the main airflow channel is...). Figure 2(Solid line arrow direction) At this time, the airflow in the main airflow channel can come from the wall inside the box 10, while an auxiliary airflow channel is formed at the side wall position of the partition platform 41 near the wall door 20 (the flow path of the auxiliary airflow channel is... Figure 2 (In the direction of the dashed arrow), the airflow in the auxiliary airflow channel can come from the bottom surface inside the cabinet 10, or it can be airflow conducted upward from the bottom of the first drawer 30. The guide member 42 is set on the partition platform 41 along the length L of the refrigerator compartment 1, and extends upward in the vertical direction H relative to the partition platform 41. The guide member 42 is staggered with the first drawer 30 in the width W of the refrigerator compartment 1, thereby realizing the upward flow of airflow in the main airflow channel and the auxiliary airflow channel from the side of the first drawer 30.

[0078] With this configuration, the main airflow channel and the auxiliary airflow channel located at the bottom of the first drawer 30 can be separated by the baffle platform 41 of the airflow guide device. The main airflow channel is formed in the gap between the baffle platform 41 and the bottom of the first drawer 30, and the auxiliary airflow channel is formed on the side wall of the baffle platform 41 near the wall door 20. The airflow in the main airflow channel flows from the bottom of the first drawer 30 to the position of the airflow guide 42, and the airflow in the auxiliary airflow channel flows from the side wall of the baffle platform 41 to the position of the airflow guide 42. After being guided vertically upward by the airflow guide 42, the airflow in both channels can be transmitted upward without impacting the bottom of the first drawer 30. It also avoids the impact between the airflow and the wall door 20 and the impact between the two airflows, greatly improving the upward transmission effect of cold air in the refrigerator compartment 1.

[0079] Furthermore, such as Figure 2 As shown, when a door shelf 21 is provided on the wall door 20 of the refrigerator compartment 1 corresponding to the first drawer 30, the size of the first drawer 30 in the width direction W of the refrigerator compartment 1 is relatively reduced, and a gap is reserved between the first drawer 30 and the door shelf 21. At this time, the end of the air guide 42 extending upward in the vertical direction H can be directly aligned with this gap, so that the air guide 42 is staggered with the first drawer 30 in the width direction W of the refrigerator compartment 1, and the airflow is transmitted upward through this gap. If a door shelf 21 is not provided on the wall door 20 of the refrigerator compartment 1 corresponding to the first drawer 30, the size of the first drawer 30 in the width direction W of the refrigerator compartment 1 can be adjusted as needed, so that a gap is left between the first drawer 30 and the wall door 20 of the refrigerator compartment 1, and the end of the air guide 42 extending upward in the vertical direction H can also be directly aligned with this gap.

[0080] like Figure 3As shown, the partition platform 41 includes a second drawer 411 and a partition plate 412. When multiple drawers are arranged vertically (H) inside the refrigerator compartment 1, the upper drawer in adjacent layers is the first drawer 30, and the lower drawer is the second drawer 411. The partition plate 412 is located at the top of the second drawer 411, forming a main airflow channel between it and the bottom of the first drawer 30. An auxiliary airflow channel is formed on the side wall of the second drawer 411 near the door 20. A guide element 42 is installed on the partition plate 412. This arrangement allows the second drawer 411, located below the first drawer 30, to combine with the partition plate 412 to form the partition platform 41, further reducing the space occupied by the partition platform 41 without affecting the existing structure of the refrigerator compartment 1. Simultaneously, the partition plate 412, located at the top of the second drawer 411, and the guide element 42 on the partition plate 412 facilitate airflow guidance. However, if a second drawer 411 is not provided below the first drawer 30, a similar partition platform 41 can be provided directly below the first drawer 30 to guide the airflow in the two channels using the guide member 42 on the partition platform 41.

[0081] like Figure 3 and Figure 4 As shown, the flow guide 42 is set on the partition platform 41 and extends upward in the vertical direction H when there is no external force. The top of the extension is located above the bottom of the first drawer 30. When the wall door 20 of the refrigerator compartment 1 is opened, the first drawer 30 can be pulled horizontally along the width direction W of the refrigerator compartment 1. During the pulling and moving process, it abuts against the flow guide 42 and drives the flow guide 42 to flip relative to the partition platform 41. With this arrangement, when the wall door 20 of the refrigerator compartment 1 is closed, the first drawer 30 and the air guide 42 are misaligned, and the air guide 42 is in a state without external force. At this time, the air guide 42 extends upward in the vertical direction H relative to the partition platform 41, and the top of the extension is located above the bottom of the first drawer 30 to increase the upward extension size, thereby more effectively guiding the airflow upward inside the refrigerator compartment 1. When the wall door 20 of the refrigerator compartment 1 is opened, the first drawer 30 comes into contact with the air guide 42 during the horizontal outward pulling process, and drives the air guide 42 to flip relative to the partition platform 41, so that the arrangement of the air guide 42 will not affect the use of the first drawer 30.

[0082] However, in other embodiments, if the gap between the partition platform 41 and the bottom of the first drawer 30 is large enough, the end of the guide member 42 extending upward in the vertical direction H on the partition platform 41 may not exceed the bottom of the first drawer 30, so that the guide member 42 can guide the airflow without affecting the pulling of the first drawer 30 relative to the box 10 even if it is not flipped.

[0083] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, the flow guiding device also has a base 43 on the partition platform 41. The base 43 and the flow guiding component 42 extend along the length L of the refrigerator compartment 1. An arc-shaped groove 431 is provided on the top of the base 43. The bottom of the flow guiding component 42 is rotatably disposed in the arc-shaped groove 431, and the top of the flow guiding component 42 can be more easily flipped during rotation. With this configuration, the top size and shape of the flow guiding component 42 can be set as needed, so that the center of gravity of the flow guiding component 42 is located at the bottom of the flow guiding component 42, making it easier for the flow guiding component 42 to be in a vertically upward extending state relative to the partition platform 41 when no external force is applied. In this embodiment, the bottom of the flow guiding component 42 is an arc surface, and the top of the flow guiding component 42 is an extended plate-like structure, so that the cross-sectional shape of the entire flow guiding component 42 is similar to the shape of a "shovel" or "spoon". This configuration makes it easier for the center of gravity of the flow guiding component 42 to be located at the bottom of the flow guiding component 42. Of course, in other embodiments, the guide member 42 can be configured with other shapes as needed, as long as it can cooperate with the base 43 and play the role of guiding airflow. At the same time, in other embodiments, the purpose of making the guide member 42 extend vertically upward relative to the partition platform 41 when no external force is applied can also be achieved by other structural forms, such as by setting a spring or other reset element to act on the guide member 42.

[0084] like Figure 7 As shown, the partition platform 41 has an opening 413 at the position corresponding to the base 43. The base 43 is fitted into the opening 413, and the driving component 44 of the airflow guiding device drives the base 43 to move vertically H within the opening 413. With this arrangement, when the first drawer 30 is pulled out horizontally, the driving component 44 can first drive the base 43 to move vertically H within the opening 413, so that the airflow guiding component 42 on the base 43 can also move vertically H relative to the partition platform 41, further avoiding interference of the airflow guiding component 42 with the pulling of the first drawer 30; at the same time, the dimension of the airflow guiding component 42 extending upward in the vertical direction H can be further increased to improve its airflow guiding effect.

[0085] Specifically, such as Figure 7As shown, in this embodiment, the driving component 44 specifically employs the cooperation of an electromagnetic relay 441 and a magnet 442. The electromagnetic relay 441 and the magnet 442 are respectively disposed on the bottom surface of the opening 413 and on the base 43. When the electromagnetic relay 441 is energized, it acts on the magnet 442, causing the magnet 442 to drive the base 43 to move within the opening 413. This arrangement is structurally simpler and more convenient to operate compared to other driving methods. Of course, in other embodiments, the driving component 44 can adopt other structures existing in the prior art to drive the base 43 together with the guide component 42 to move within the opening 413.

[0086] like Figure 4 , Figure 5 and Figure 7 As shown, the flow guiding device also includes a rotating shaft 45, which passes through the bottom of the flow guiding member 42 along the length L of the refrigerator compartment 1. The refrigerator compartment 1 has two corresponding limiting grooves 11 on its two side walls along the length L. The two ends of the rotating shaft 45 extending out of the flow guiding member 42 are respectively accommodated in the corresponding limiting grooves 11. With this arrangement, during the flipping or lifting movement of the flow guiding member 42 relative to the partition platform 41, the two ends of the rotating shaft 45 extending out of the flow guiding member 42 are accommodated in the limiting grooves 11 located on the side walls of the cabinet 10, thus limiting the flow guiding member 42 and preventing it from deviating from its predetermined position during movement, thereby ensuring the repeated and effective use of the flow guiding device. Specifically, the limiting groove 11 is a racetrack-shaped groove. The straight section of the racetrack-shaped groove extends vertically H along the corresponding side wall of the housing 10. The sum of the vertically movable dimension of the base 43 within the opening 413 and the diameter of the rotating shaft 45 is less than the length of the racetrack-shaped groove. By setting this length, both ends of the rotating shaft 45 extending from the guide member 42 can move within the corresponding racetrack-shaped groove. This limits the flow guide member 42 while preventing it from detaching from the base 43 during movement, thus improving the stability and reliability of the flow guide device.

[0087] like Figure 6 and Figure 7As shown, the flow guiding device also includes a limiting member 46, which is disposed on the surface of the partition platform 41 where the opening 413 is opened and covers a part of the opening 413. The bottom edge of the base 43 is provided with a step portion 432, which can abut against the limiting member 46 in the opening 413 to limit the size range of the base 43 that can move in the vertical direction H in the opening 413 as needed. It also prevents the base 43 from detaching from the partition platform 41 when moving in the opening 413, thereby further improving the reliability of the flow guiding device. Specifically, the limiting member 46 is respectively arranged on both sides of the guide member 42 along the width direction W of the refrigerator compartment 1, and the base 43 is provided with concave arc surface 433 on both sides of the guide member 42. When the step portion 432 abuts against the limiting member 46, the concave arc surface 433 smoothly transitions with the upper surface of the corresponding limiting member 46, so that the airflow can move upward along the smoothly transitioned concave arc surface 433, further improving the airflow guiding effect of the guide device.

[0088] like Figure 7 As shown, when the driving component 44 specifically includes an electromagnetic relay 441 and a magnet 442, the flow guiding device is also provided with an elastic component 47. The elastic component 47 is disposed in the opening 413 of the partition platform 41. The linkage rod of the elastic component 47 abuts against the bottom surface of the opening 413 and the base 43 respectively. When the electromagnetic relay 441 is energized, it acts on the magnet 442, causing the magnet 442 to approach the electromagnetic relay 441, thereby driving the base 43 to move vertically downward in the opening 413, which in turn causes the flow guiding component 42 to move vertically downward as well. During the entire movement, the base 43 presses against the elastic component 47. Through this arrangement, by utilizing the cooperation of the driving component 44 and the elastic component 47, when the electromagnetic relay 441 in the driving component 44 is energized, the base 43 moves vertically downward in the opening 413, and when it is de-energized, the elastic component 47 causes the base 43 to return to its original position. This improves the automatic reset capability of the base 43 relative to the partition platform 41, making the flow guiding device reusable and effective. In this embodiment, the elastic element 47 is specifically a compression spring. However, in other embodiments, existing elastic elements with retraction functions can be used.

[0089] Furthermore, the door 20 of the refrigerator compartment 1 can be linked to the electromagnetic relay 441 through circuitry or sensors. When the door 20 is open, the electromagnetic relay 441 is energized. With this configuration, when the door 20 of the refrigerator compartment 1 is open, it directly drives the base 43 to move vertically downwards through the opening 413 of the partition platform 41. This causes the guide section on the base 43 to also move vertically downwards, allowing the first drawer 30 to be pulled out of the cabinet 10. This minimizes the impact of the guide device on the use of the first drawer 30, improving the user experience. However, it should be noted that the linkage control between the door 20 of the refrigerator compartment 1 and the electromagnetic relay 441 can employ existing linkage control methods, which will not be elaborated upon here.

[0090] Furthermore, in another specific embodiment, such as Figure 7 As shown, the elastic element 47 can also be omitted. When the driving element 44 specifically includes an electromagnetic relay 441 and a magnet 442, when the electromagnetic relay 441 is energized, it acts on the magnet 442, causing the magnet 442 to move away from the electromagnetic relay 441, thereby driving the base 43 to move upward within the opening 413. This causes the guide element 42 to also move vertically upward. When the electromagnetic relay 441 is de-energized, the base 43 uses its own weight to move vertically downward within the opening 413, thereby driving the guide element 42 to also move vertically downward. With this arrangement, by utilizing the cooperation of the driving element 44 and the weight of the base 43, the base 43 moves vertically upward within the opening 413 when the electromagnetic relay 441 is energized, and moves vertically downward within the opening 413 when it is de-energized. This improves the ability of the base 43 to move and reset, allowing the guide device to be used repeatedly and effectively.

[0091] Furthermore, the door 20 of the refrigerator compartment 1 can be linked to the electromagnetic relay 441 through circuitry or sensors. When the door 20 is open, the electromagnetic relay 441 is de-energized; when the door 20 is closed, the electromagnetic relay 441 is energized. With this configuration, when the door 20 of the refrigerator compartment 1 is open, the electromagnetic relay 441 is de-energized, allowing the base 43 to move vertically downwards within the opening 413 using its own weight. This allows the first drawer 30 to be pulled out of the cabinet 10, minimizing the impact of the flow guide device on the use of the first drawer 30 and improving the user experience. Similarly, the linkage control between the door 20 of the refrigerator compartment 1 and the electromagnetic relay 441 can employ existing linkage control methods, which will not be elaborated upon here.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
