[0020] In some embodiments, the main drawer includes:

[0021] Upper storage room;

[0022] A lower storage chamber is disposed at the bottom of the upper storage chamber and connected to the upper storage chamber. The width of the lower storage chamber is smaller than the width of the upper storage chamber, so as to form a stepped portion on the second side.

[0023] A sliding plate is disposed on the inner wall of the lower storage chamber and located below the step portion to support the partition;

[0024] The lower storage chamber has a slot for insertion on its side wall. The slot is located below the step and its outline matches the cross-sectional shape of the partition assembly, allowing the partition assembly to pass through.

[0031] The technical solutions provided in this application have the following advantages compared with the prior art:

[0032] The drawer structure provided in this application embodiment achieves two-dimensional pull-out operation by having the main drawer assembly move along the width of the compartment and the secondary drawer assembly move along the length. Users can flexibly divide and store food according to their needs, solving the problem of inconvenient retrieval due to food accumulation in existing drawer structures. At the same time, the partition assembly not only seals the opening of the secondary drawer assembly to reduce cold loss, but also serves as an additional storage surface, thereby further optimizing the utilization of storage space. Cold air is directly delivered into the secondary drawer assembly through the air supply duct and partition assembly, combined with the return air channel and return air duct, forming a refrigeration cycle for the secondary drawer assembly. This allows for targeted and rapid freezing (quick freezing) of the food in the secondary drawer assembly without activating the cooling mode of the entire compartment, improving the user experience and reducing energy waste.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0062] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0063] As people's living standards continue to improve, consumers have higher requirements for the longevity of food preservation and ease of use of refrigerators, making frost-free refrigerators the mainstream choice in the market. Currently, most frost-free refrigerators on the market adopt a built-in large drawer structure for the freezer compartment. This structure, by combining the freezer compartment with drawer-type storage units, can effectively utilize vertical space, thereby achieving a larger storage capacity and meeting the family's storage needs for large amounts of frozen food.

[0064] However, this traditional drawer-style structure still has obvious technical defects in actual use: On the one hand, since there is no effective partitioning structure inside the drawer, various frozen foods are usually stored in a pile-up state. When users need to retrieve a specific item, they have to search through the entire drawer, which is not only cumbersome, but may also cause temperature fluctuations in other foods due to frequent rummaging, affecting the preservation effect; On the other hand, the cooling and air supply system of existing air-cooled refrigerators is usually uniformly controlled for the entire freezer compartment. Its air duct design cannot achieve precise air supply to specific areas inside the drawer. When users need to quickly freeze a small amount of newly put-in food (i.e., quick-freeze), they can only start the quick-freeze mode of the entire compartment. This not only causes unnecessary energy consumption, but may also adversely affect the quality of other foods already stored in the drawer due to the sudden drop in overall temperature.

[0065] In response to the above technical problems, such as Figures 1-10 , Figure 17 , Figure 18As shown, this application embodiment provides a drawer structure 3, including a main drawer assembly 10, a secondary drawer assembly 20, a partition assembly 30, and an air circulation assembly 40; the main drawer assembly 10 is movably disposed within a compartment 1 and one end is connected to a door 2, the main drawer assembly 10 is movable along the width direction of the compartment 1, and is configured to form a return air channel 50 between the compartment 1 and the door 2; the secondary drawer assembly 20 is movably disposed within the main drawer assembly 10 and communicates with the return air channel 50, the secondary drawer... Component 20 is configured to move along the length of compartment 1; partition assembly 30 is disposed inside main drawer assembly 10 and above secondary drawer assembly 20, partition assembly 30 is configured to close the opening of secondary drawer assembly 20; air duct circulation assembly 40 is disposed inside compartment 1, air duct circulation assembly 40 is connected to secondary drawer assembly 20 through partition assembly 30 to deliver cold air into secondary drawer assembly 20, and air duct circulation assembly 40 is connected to return air duct 50 to recover the cold air after heat absorption and heating.

[0066] As can be seen above, by moving the main drawer assembly 10 along the width of compartment 1 and the secondary drawer assembly 20 along the length, a two-dimensional pull-out operation is achieved. Users can flexibly divide and store food according to their needs, solving the problem of food accumulation and inconvenience in searching in the existing drawer structure 3. At the same time, the partition assembly 30 not only seals the opening of the secondary drawer assembly 20 to reduce cold loss, but also serves as an additional storage surface, thereby further optimizing the utilization rate of storage space. Cold air is directly delivered into the secondary drawer assembly 20 through the air circulation assembly 40 and the partition assembly 30, combined with the return air channel 50, to form a refrigeration cycle for the secondary drawer assembly 20, which performs targeted rapid freezing (quick freezing) of the food in the secondary drawer assembly 20 without activating the refrigeration mode of the entire compartment 1, improving the user experience and reducing energy waste.

[0067] It should be noted that compartment 1 refers to the area inside the refrigerator that is divided by partitions or independent cavities; the refrigerator includes multiple compartments 1, some compartments 1 are refrigerator compartments, used to provide a refrigerated storage environment; another part of compartments 1 are freezer compartments, used to provide a frozen storage environment; and the main drawer assembly 10 is located in the freezer compartment; the door 2 refers to the dynamic component that maintains the airtightness of compartment 1. When the door 2 closes the opening of compartment 1, compartment 1 is an independent space unit.

[0068] It should also be noted that, such as Figures 2-4 As shown, the length direction of compartment 1 is parallel to the X direction, and the width direction of compartment 1 is parallel to the Y direction.

[0069] It should also be noted that when a user takes or puts items in the secondary drawer assembly 20, the secondary drawer assembly 20 can be pulled out along the length direction to expose it, without being restricted by whether or not food is placed on the partition assembly 30. This makes the operation more flexible and convenient, avoiding the cumbersome steps of having to remove food from the partition assembly 30 before taking out items in the secondary drawer 210, effectively improving the efficiency of taking and putting things in and the user experience.

[0070] It should also be noted that the refrigerator includes a refrigeration system, which includes an evaporator and an air duct connected to the evaporator. The air duct is equipped with an air inlet and an air outlet. The air duct circulation component 40 is connected to the air inlet and the air outlet respectively. The cold air that has absorbed heat and been heated is delivered to the air inlet through the return air duct 50 and the air duct circulation component 40. After being cooled by the refrigeration system, the cold air flows back into the air duct circulation component 40 from the air outlet and is delivered to the auxiliary drawer component 20 for cooling. This cycle repeats continuously.

[0071] like Figure 10 , Figure 16 As shown, in some embodiments, the partition assembly 30 includes a partition 310 and an air supply component 320; the partition 310 is movably disposed on the main drawer assembly 10, and the partition 310 is movable in the width direction to open or close the opening of the secondary drawer assembly 20; the air supply component 320 is disposed at the bottom of the partition 310, one end of the air supply component 320 is connected to the air duct circulation assembly 40 and the other end is blocked; wherein, the air supply component 320 has an air supply channel 3201 inside, and an air supply hole 3202 connected to the air supply channel 3201 is provided on the side wall of the air supply component 320 to introduce cold air into the secondary drawer assembly 20.

[0072] The partition 310 moves along its width to open or close the opening of the secondary drawer assembly 20, ensuring its airtightness to reduce cold loss and improve rapid cooling efficiency. It also provides a passage for accessing food within the secondary drawer assembly 20, offering multiple ways for users to retrieve and store food, thus facilitating their needs. By integrating an air conveyor 320 at the bottom of the partition 310, the cold air delivery and partitioning functions are combined, simplifying the overall structural layout and allowing cold air to be directed into the interior of the secondary drawer assembly 20 for efficient cooling of the food. Furthermore, sealing one end of the conveyor prevents unnecessary cold air diffusion, improving cold energy utilization efficiency.

[0073] It should be noted that the air supply component 320 includes a first air supply sidewall and a second air supply sidewall arranged opposite each other in the length direction. Multiple air supply holes 3202 are respectively arranged on the first air supply sidewall and the second air supply sidewall. The multiple air supply holes 3202 are arranged at intervals in the width direction, thereby forming multi-point uniform air supply, so that the cold air can be uniformly guided into the interior of the secondary drawer assembly 20, avoiding local air outlets that would cause uneven temperature inside the secondary drawer assembly 20, so as to achieve efficient cooling.

[0074] It should also be noted that, such as Figure 6 As shown, the opening of the secondary drawer assembly 20 is located at the top of the secondary drawer assembly 20.

[0075] like Figure 17 As shown, in some embodiments, the return air duct 50 includes a first return air section 510 and a second return air section 520, the second return air section 520 being connected to the first return air section 510 and the air duct circulation assembly 40 respectively; wherein, the main drawer assembly 10 includes a first side 110 and a second side 120 disposed opposite to each other in the width direction, the first side 110 and the inner wall of the door 2 forming the first return air section 510, the second side 120 and the bottom of the main drawer assembly 10 and the inner wall of the compartment 1 forming the second return air section 520.

[0076] The orderly planning of the return air path is achieved through the first return air section 510 and the second return air section 520. The first return air section 510 is constructed by utilizing the gap between the first side 110 and the inner wall of the door 2, and the second return air section 520 is constructed by utilizing the space between the second side 120, the bottom of the main drawer assembly 10 and the inner wall of the compartment 1. This fully utilizes the gap space between the main drawer assembly 10 and the surrounding structure, avoiding additional storage space occupation, and also constructs a complete return air channel 50. In addition, the multi-segment return air structure can balance the air pressure distribution around the main drawer assembly 10, avoid temperature dead zones caused by local airflow stagnation, and ensure the overall temperature stability of the compartment 1.

[0077] like Figure 14 , Figure 15 , Figure 17 As shown, in some embodiments, a plurality of air outlets 1101 are provided on the first side 110. The air outlets 1101 are located between the partition assembly 30 and the secondary drawer assembly 20, so as to introduce the cold air after heat absorption and heating into the first return air section 510.

[0078] By placing the air outlet 1101 in the space between the partition assembly 30 and the secondary drawer assembly 20, the cold air that has accumulated in the secondary drawer assembly 20 after absorbing heat and heating up can be directly introduced into the first return air section 510. This avoids the need for the cold air to diffuse after absorbing heat and heating up, shortens the return path, and thus improves return efficiency and reduces cold energy waste. At the same time, the shortened return path also accelerates the air renewal in the secondary drawer assembly 20, forming efficient convection with the new cold air introduced by the air supply component 320, ensuring that the temperature in the secondary drawer assembly 20 remains at a stable low temperature, and preventing local temperature rise due to the stagnation of cold air after absorbing heat and heating up. In addition, the direct connection between the air outlet 1101 and the first return air section 510 makes the structure more compact, and the multiple air outlets 1101 form multi-point return air, avoiding local airflow concentration.

[0079] It should be noted that, as Figure 14 , Figure 15 As shown, multiple air outlets 1101 can be arranged at intervals along the length direction.

[0080] like Figure 5 , Figure 6 As shown, in some embodiments, the main drawer assembly 10 includes a bracket 130, a main drawer 140, and an upper drawer 150; the bracket 130 is movably disposed on the inner wall of the compartment 1 and one end is connected to the door 2; the main drawer 140 is disposed on the bracket 130, and a main opening 1401 is provided on the top of the main drawer 140; the upper drawer 150 is movably disposed in the compartment 1 and located on top of the main drawer 140, and the upper drawer 150 is optionally connected to the main drawer 140; wherein, an air vent 1101 is provided on the main drawer 140.

[0081] The bracket 130 provides a support base for the main drawer 140. The main drawer 140 can be pulled out by moving the bracket 130 in the width direction. The main drawer 140 and the upper drawer 150 form a layered storage space, further improving space utilization. Simultaneously, using the main drawer 140 as the main support for the secondary drawer assembly 20, and with the air outlet 1101 located on the main drawer 140, prevents the air outlet 1101 from shifting position or functionally interfering with the drawer's movement, ensuring stable return air and reliable precise cooling.

[0082] It should be noted that the bracket 130 includes two support frames arranged at intervals along the length direction. One end of the two support frames is connected to the door 2. The bracket 130 also includes a reinforcing rod, the two ends of which are connected to the two support frames respectively, thereby improving the overall strength and reliability of the bracket 130. The main drawer 140 is installed on the bracket 130 by means of snap-fit, including but not limited to.

[0083] It should also be noted that, such as Figure 6As shown, upper sliders 1501 and lower sliders 1502 are installed on both side walls of the upper drawer 150, forming a sliding channel between them; a sliding column is provided on the side wall of the compartment 1, which cooperates with the sliding channel to achieve a sliding connection between the upper drawer 150 and the compartment 1; in addition, as Figure 5 , Figure 7 , Figure 10 As shown, part of the upper drawer 150 is located inside the main drawer 140. A notch is provided on the first side 110 of the main drawer 140 to avoid interference and ensure the independent pulling out of the upper drawer 150.

[0084] It should also be noted that, such as Figure 6 As shown, limit blocks 1503 are respectively provided on the two side walls of the upper drawer 150, and limit grooves 1411 are respectively provided on the third side 160 and the fourth side 170 of the main drawer 140; the limit grooves 1411 cooperate with the limit blocks 1503; when the drawer structure 3 is located in the compartment 1 and the compartment door 2 is closed, the limit blocks 1503 are inserted into the limit grooves 1411, and the upper drawer 150 is connected to the main drawer 140. Therefore, when the compartment door 2 is pulled, the entire drawer structure 3 moves together away from the compartment 1. When the user wants to take out the food placed in the partition assembly 30 and the secondary drawer 210, the upper drawer 150 can be pushed to make the limit blocks 1503 leave the limit grooves 1411 and move the upper drawer 150 into the compartment 1. In addition, the limiting block 1503 and the limiting groove 1411 can be set as inclined surfaces on the side near the compartment 1 so that the upper drawer 150 can be quickly disconnected from the main drawer 140, making it convenient to push the upper drawer 150 into the compartment 1.

[0085] It should also be noted that, such as Figure 17 As shown, there is a gap between the first side 110 of the main drawer 140 and the inner wall of the door 2, which provides a structural basis for forming the first return air section 510.

[0086] like Figures 12-15 As shown, in some embodiments, the main drawer 140 includes an upper storage chamber 1402, a lower storage chamber 1403, and a slide plate 1404; the lower storage chamber 1403 is disposed at the bottom of the upper storage chamber 1402 and communicates with the upper storage chamber 1402, and the width of the lower storage chamber 1403 is smaller than the width of the upper storage chamber 1402 to form a step portion 1407 on the second side 120; the slide plate 1404 is disposed on the inner wall of the lower storage chamber 1403 and located below the step portion 1407 to support the divider 310; wherein, the side wall of the lower storage chamber 1403 is provided with an insertion slot 1405, the insertion slot 1405 is located below the step portion 1407 and its outline shape matches the cross-sectional shape of the partition assembly 30 so that the partition assembly 30 can pass through.

[0087] By setting up an upper storage chamber 1402 and a lower storage chamber 1403, the main drawer 140 achieves layered storage. The upper storage chamber 1402 stores food ingredients, while the lower storage chamber 1403 accommodates the secondary drawer assembly 20, improving the efficient use of space. The step 1407 provides a base for the installation and positioning of the partition assembly 30, making the structural layout more compact. The sliding plate 1404 supports the divider 310, ensuring its stability when moving along its width, thus preventing the divider 310 from shaking and affecting the sealing effect of the secondary drawer assembly 20 opening and the accuracy of cold air delivery. The insertion slot 1405 and the step 1407 provide space for the movement of the partition assembly 30, reserving ample room for movement and avoiding structural interference. Furthermore, the insertion slot 1405, with its shape matching the partition assembly 30, not only guides the partition assembly 30 during movement but also provides a channel for the connection between the air duct 410 and the conveyor components.

[0088] It should be noted that, as Figure 15 As shown, the main drawer 140 includes a third side 160 and a fourth side 170 arranged opposite each other in the length direction, and a slide plate 1404 is disposed on the inner wall of the first side 110, the third side 160, and the fourth side 170.

[0089] It should also be noted that, such as Figure 15 , Figure 17 As shown, a plurality of return air holes 1102 are provided on the first side 110 of the upper storage chamber 1402. The plurality of return air holes 1102 are arranged at intervals along the length direction and are connected to the first return air flow section 510. The return air holes 1102 are located below the upper drawer 150. The cold air in the upper storage chamber 1402, after being heated by heat absorption, is introduced into the first return air flow section 510 through the return air holes 1102, and then flows into the refrigeration system through the first return air flow section 510 and the second return air flow section 520.

[0090] It should also be noted that the volume of the upper storage chamber 1402 is larger than that of the lower storage chamber 1403. The cooling speed of the upper storage chamber 1402 is slow. From the perspective of cooling speed, the auxiliary drawer assembly 20 is placed in the lower storage chamber 1403, and the lower storage chamber 1403 is used as the quick-freezing chamber 1.

[0091] It should also be noted that the cross-section of the partition assembly 30 is a section perpendicular to the width direction, and this cross-section is connected to the air supply component 320 via the separator 310.

[0092] It should also be noted that, such as Figure 10 As shown, a handle 330 is provided on the top of the divider 310. The handle 330 not only facilitates the user's movement of the divider 310, but also serves as a limit element, reminding the user to stop moving the divider 310; as Figure 19 , Figure 20 As shown, when the handle 330 moves to abut against the step 1407, it prompts the user to stop moving the divider 310, at which point the secondary drawer assembly 20 is exposed; as Figure 10 As shown, when the end face of the divider 310 moves to abut against the inner wall of the first side 110, the user is reminded to stop moving the divider 310, and at this time the opening of the secondary drawer assembly 20 is closed.

[0093] like Figure 14 As shown, in some embodiments, a perimeter 1406 is provided on the outer wall of the lower storage chamber 1403, which extends along the bottom edge of the insertion slot to support the partition assembly 30.

[0094] By setting the perimeter 1406 to enhance the support capacity of the partition assembly 30, the stability of the partition assembly 30 during movement is ensured, thereby further ensuring the accuracy of the partition assembly 30 in closing or opening the secondary drawer assembly 20.

[0095] like Figure 17 , Figure 18 As shown, in some embodiments, the air circulation assembly 40 includes an air supply duct 410 and a return air duct 420, the air supply duct 410 being connected to the partition assembly 30 and the return air duct 420 being connected to the return air channel 50.

[0096] By connecting the supply air duct 410 to the partition assembly 30 and the return air duct 420 to the return air channel 50, a complete closed loop of supply air, cooling, and return air can be formed, ensuring efficient circulation of cold air and improving cooling efficiency. Simultaneously, it enables precise directional temperature control of the secondary drawer 210, meeting the preservation needs of different foods and reducing spoilage caused by temperature fluctuations. Furthermore, using the partition assembly 30 as one of the air duct sections for delivering cold air optimizes space utilization.

[0097] It should be noted that the end of the air supply duct 410 away from the partition assembly 30 is connected to the air outlet, and the end of the return air duct 420 away from the return air channel 50 is connected to the air inlet. The cold air that has absorbed heat and been heated is delivered to the air inlet through the return air channel 50 and the return air duct 420. After being cooled by the refrigeration system, the cold air flows back into the air supply duct 410 from the air outlet and is delivered to the auxiliary drawer assembly 20 for cooling. This cycle repeats continuously.

[0098] like Figure 17 , Figure 18 As shown, in some embodiments, the air supply duct 410 includes a first air supply section 4101, which is coaxially aligned with the air conveyor 320 and is configured to be inserted into the air conveyor 320; wherein, a quick-freezing damper 4104 is provided inside the air supply duct 410 to control the opening and closing of the air supply duct 410.

[0099] The connection between the first air supply section 4101 and the air conveyor 320 is achieved by coaxially aligning the first air supply section 4101 with the air conveyor 320 and inserting it into the air conveyor 320. This method is flexible, simple, and convenient, and also reduces the gap at the connection point, avoiding cold air loss caused by disordered diffusion at the connection point, thereby ensuring the supply of cold air to the auxiliary drawer assembly 20. The quick-freezing damper 4104 flexibly controls the opening and closing of the air supply pipe 410. When the food in the auxiliary drawer assembly 20 is quick-frozen or kept at a low temperature, the quick-freezing damper 4104 is opened to continuously deliver cold air; when the auxiliary drawer assembly 20 does not require additional cooling, the quick-freezing damper 4104 is closed to avoid unnecessary consumption of cold air and achieve rational use of energy.

[0100] It should be noted that, as Figure 17 As shown, when the door 2 closes the compartment 1, there is a gap between the second side 120 of the main drawer assembly 10 and the rear wall of the compartment 1; the air supply duct 410 also includes a second air supply section 4105 that communicates with the first air supply section 4101. The second air supply section 4105 is located between the second side 120 and the rear wall of the compartment 1, and an air inlet 4106 is provided on the second air supply section 4105; in addition, the air duct of the refrigeration system can be set between the rear wall of the compartment 1 and the second air supply section 4105, and the air duct is connected to the second air supply section 4105 through the air inlet 4106 to deliver cold air.

[0101] It should also be noted that, such as Figure 6 As shown, the drawer structure 3 also includes a temperature sensor 60 disposed within the secondary drawer assembly 20. The refrigerator's control system is electrically connected to the temperature sensor 60 and the quick-freeze damper 4104. When the temperature sensor 60 senses that the real-time temperature within the secondary drawer assembly 20 is higher than the preset temperature, the refrigerator's control system activates the quick-freeze function, controlling the quick-freeze damper 4104 to open, allowing cold air to flow into the secondary drawer assembly 20 for quick-freezing. When the temperature sensor 60 senses that the real-time temperature within the secondary drawer assembly 20 is lower than the preset temperature, the refrigerator's control system controls the quick-freeze damper 4104 to close, thereby completing the quick-freeze process within the secondary drawer assembly 20. Furthermore, the temperature sensor 60 includes, but is not limited to, an infrared temperature sensor 60, and the preset temperature is the temperature required for quick-freezing.

[0102] It should also be noted that the outer diameter of the first air supply section 4101 is less than or equal to the inner diameter of the air supply component 320, and their shapes are matched so that the first air supply section 4101 can be inserted into the air supply component 320.

[0103] like Figure 6 , Figure 11 , Figure 18As shown, in some embodiments, the secondary drawer assembly 20 includes two secondary drawers 210, which are arranged opposite to each other along the length direction and have opposite pulling directions; wherein, the air supply component 320 includes two air supply channels 3201, which are separated and correspond one-to-one with the two secondary drawers 210 respectively, and the air supply channels 3201 introduce cold air into the corresponding secondary drawers 210; the first air supply section 4101 is provided with two air supply branches 4102, which are separated and correspond one-to-one with the two air supply channels 3201 respectively, and the air supply branches 4102 deliver cold air into the corresponding air supply channels 3201.

[0104] The two drawers 210 are connected by independent air supply branches 4102 and air delivery channels 3201, forming two independent air supply systems. This allows for targeted cooling of different drawers 210, enabling individual control of the cooling status of each drawer 210. Specifically, when one drawer requires rapid freezing, cold air is delivered through its corresponding air supply branch 4102 and air delivery channel 3201, while the other drawer can supply cold air or stop air supply as needed. The opposite pulling directions of the two drawers 210 allow users to independently pull out the corresponding drawer 210 based on the location of the food, avoiding mutual interference.

[0105] It should be noted that the quick-freezing damper 4104 can control the opening and closing of two air supply branches 4102, and the opening and closing of the two air supply branches 4102 are independent of each other and do not interfere with each other; for example, the quick-freezing damper 4104 can be a dual-motor dual-blade damper, with each blade controlled by a motor, or the quick-freezing damper 4104 can be a magnetic levitation dual damper; this application will not elaborate further.

[0106] It should also be noted that, such as Figure 16 As shown, an air supply baffle 3203 is provided inside the air supply component 320, thereby forming two air supply channels 3201. The two air supply channels 3201 adopt a shared wall design to save space; as Figure 18 As shown, an air supply baffle 4103 is provided in the first air supply section 4101, thereby forming two air supply branches 4102. The two air supply branches 4102 adopt a shared wall design to save space.

[0107] It should also be noted that, such as Figure 13 As shown, mounting openings 1408 are provided on the third side 160 and the fourth side 170 of the lower storage compartment 1403 to provide space for the installation of the secondary drawer assembly 20; as Figure 6 , Figure 14As shown, the lower storage compartment 1403 is provided with a first slide 1409 and a second slide 1410 arranged vertically on the first side 110 and the second side 120, respectively. A moving channel is formed between the first slide 1409 and the second slide 1410. A guide column 2101 is provided on the side wall of the auxiliary drawer 210. The guide column 2101 cooperates with the moving channel to realize the movement of the auxiliary drawer 210.

[0108] It should also be noted that, such as Figure 15 As shown, a partition is provided in the lower storage chamber 1403, dividing the lower storage chamber 1403 into two storage spaces, and two drawer assemblies 20 are located in the two storage spaces respectively.

[0109] In summary, the drawer structure 3 provided in this application has multiple independent small spaces for user storage, and can achieve rapid cooling only for the secondary drawer assembly 20, meeting specific user needs; at the same time, the drawer structure 3 can change the storage method and the opening method of the secondary drawer assembly 20 by adjusting the position of the partitions, specifically:

[0110] Method 1: As Figure 19 , Figure 20 As shown, when storing food in the secondary drawer 210, first open the door 2. If there is no other stored food on the shelf assembly 30, push the upper drawer 150 into the refrigerator, then push the shelf assembly 30 to the step 1407 to abut, exposing the two secondary drawers 210. Then, put the food into the secondary drawer 210, and pull the shelf assembly 30 out to abut against the first side 110, covering the secondary drawer 210. When taking food out of the secondary drawer 210, first open the door 2. If there is no other stored food on the shelf assembly 30, push the upper drawer 150 into the refrigerator, then push the shelf assembly 30 to the step 1407 to abut, exposing the two secondary drawers 210. Then, take the food out of the secondary drawer 210.

[0111] Method 2: such as Figure 21 , Figure 22 As shown, when storing food in the secondary drawer 210, first open the compartment door 2. If there are other stored food items on the partition assembly 30, pull the secondary drawer 210 out along its length from both sides of the main drawer 140, put in the food items, then push the secondary drawer 210 back to its original position and close the compartment door 2. When taking food out of the secondary drawer 210, if there are other stored food items on the partition assembly 30, pull the secondary drawer 210 out along its length from both sides of the main drawer 140, take out the food items, then push the secondary drawer 210 back to its original position and close the compartment door 2.

[0112] like Figures 1-4 As shown in the figure, this application embodiment also provides a refrigerator, including the drawer structure 3 provided in the foregoing embodiments of this application.

[0113] It should be noted that, as Figures 1-4 As shown, the compartment 1 with freezing function is located in the lower part of the refrigerator, and the drawer structure 3 is set in this compartment 1.
