Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a combination drawer and a refrigerator. Background Art

[0002] At present, when storing items in the refrigerator, drawers are needed in most cases. The drawer structure can better divide the storage space in the refrigerator and improve the space utilization rate. However, when using the drawer to store and retrieve items in the refrigerator, the drawer needs to be pulled out of the refrigerator, which will cause a high amount of cold air leakage in the drawer, thereby causing a large temperature loss in the refrigerator, resulting in increased energy consumption of the refrigerator.

[0003] The related art adopts the method of partitioning and covering the drawers to avoid the situation where the drawers are completely pulled out and cause cold air leakage. However, in the process of pulling out the drawers, the airflow in the drawers is driven so that the airflow has a tendency to flow outward, which still causes cold air leakage and increases the energy consumption of the refrigerator.

[0004] It can be seen that how to minimize the temperature loss inside the refrigerator when storing and taking items out of the refrigerator, maintain the stability of the internal storage space, and reduce the energy consumption of the refrigerator has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The disclosed embodiments provide a combined drawer and refrigerator to solve the problem that when the drawer is pulled out, the airflow in the drawer tends to flow outward, which still causes leakage of cold air and increases the energy consumption of the refrigerator.

[0008] In some embodiments, the combined drawer includes: a first drawer, a second drawer and a locking mechanism. The second drawer is arranged at the front side of the first drawer, and its left and right sides are slidably connected to the left and right sides of the first drawer through a sliding assembly; the locking mechanism is partially rotatably connected to the side of the second drawer, and the remaining part can be adapted to lock or separate with the first drawer, and is used to lock or unlock the second drawer and the first drawer.

[0009] In some embodiments, the refrigerator includes: a combination drawer of any one of the above embodiments.

[0010] The combined drawer and refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects:

[0011] By arranging the first drawer and the second drawer front to back and using a locking mechanism to control the locking or separation between the first drawer and the second drawer, the second drawer located on the front side is used to store some items that need to be taken frequently, and the first drawer is used to store some items that are less frequently taken. When the user uses it, the locking mechanism can be used to unlock the second drawer so that the second drawer can be pulled out separately. At this time, the first drawer maintains its position inside the refrigerator unchanged, and the second drawer is pulled out separately. This can keep the first drawer stable without moving, avoid air flow activity in the first drawer, which causes leakage of cold air inside, and then maintain the temperature balance in the first drawer and reduce its temperature loss. On the one hand, it can provide a more stable storage effect, and on the other hand, it can reduce the energy consumption of the refrigerator by reducing temperature loss.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0031] Combination Figure 1-6 As shown, the embodiment of the present disclosure provides a combined drawer including: a first drawer 100, a second drawer 200 and a locking mechanism 300. The second drawer 200 is arranged at the front side of the first drawer 100, and its left and right sides are slidably connected to the left and right sides of the first drawer 100 through a sliding assembly 400; the locking mechanism 300 is partially rotatably connected to the side of the second drawer 200, and the remaining part can be adapted to lock or separate with the first drawer 100, and is used to lock or unlock the second drawer 200 and the first drawer 100.

[0032] By adopting the combined drawer provided by the embodiment of the present disclosure, the first drawer 100 and the second drawer 200 are arranged front to back, and the locking mechanism is used to control the locking or separation between the first drawer 100 and the second drawer 200, wherein the second drawer 200 located on the front side is used to store some items that need to be taken frequently, and the first drawer 100 is used to store some items that are less frequently taken. When the user uses it, the locking mechanism can be used to unlock the second drawer 200 so that the second drawer 200 can be pulled out separately. At this time, the first drawer 100 maintains its position inside the refrigerator unchanged, and the second drawer 200 is pulled out separately, so that the first drawer 100 can maintain its internal stability without moving, avoid air flow activity in the first drawer 100, which causes leakage of cold air inside it, and then maintain the temperature balance in the first drawer 100 and reduce its temperature loss. On the one hand, it can provide a more stable storage effect, and on the other hand, it can reduce the energy consumption of the refrigerator by reducing temperature loss.

[0033] Optionally, the height and width of the first drawer 100 and the second drawer 200 are the same, and the length of the first drawer 100 is 2 to 5 times the length of the second drawer 200. Preferably, the length of the first drawer 100 is 3 times the length of the second drawer 200. In this way, generally speaking, users have relatively few items that they often use, so setting the length of the second drawer 200 to be smaller can meet the daily use needs of users, while for most items, it is relatively important to keep the storage temperature stable, so setting the length of the first drawer 100 to be larger can facilitate users to store more items, better meet the use needs of general users, and improve the user experience.

[0034] Optionally, the front side plate 101 of the first drawer 100 and the rear side plate 201 of the second drawer 200 are both detachable structures. In this way, when the user does not need to use the second drawer 200 alone, or the space in the first drawer 100 cannot meet the storage needs of some large items, the front side plate 101 of the first drawer 100 and the rear side plate 201 of the second drawer 200 can be removed, so that a complete large drawer is formed between the first drawer 100 and the second drawer 200, which better meets the user's usage needs.

[0035] Optionally, the front side plate 101 of the first drawer 100 is a double-layer insulation material, and the rear side plate 201 of the second drawer 200 is a single-layer partition. In this way, in order to further maintain the temperature balance in the first drawer 100 and avoid the leakage of cold in the first drawer 100, the front side plate 101 of the first drawer 100 is set to be a double-layer insulation material. Even when the second drawer 200 is pulled out, the first drawer 100 can be prevented from leaking cold through the pores formed between the first drawer 100 and the second drawer 200, thereby improving the temperature balance in the first drawer 100, better maintaining the storage effect of the first drawer 100, and reducing energy consumption.

[0036] Optionally, the front side plate 101 of the first drawer 100 is made of a transparent material. In this way, when the user pulls out the second drawer 200, it is convenient for the user to observe the storage situation inside the first drawer 100 through the front side plate 101 of the first drawer 100, which can help the user to find items better, further avoid the user from opening the first drawer 100 unnecessarily, maintain the temperature inside the first drawer 100 stable, reduce the loss of temperature inside the first drawer 100, reduce energy consumption, and save more energy.

[0037] Optionally, a sealing strip is provided around the upper side of the first drawer 100. In this way, when the first drawer 100 is in the refrigerator, it is sealed with the upper side of the inner cavity, reducing the risk of the first drawer 100 leaking cold air through the upper side gap after the second drawer 200 is pulled out, and better maintaining the temperature stability of the first drawer 100.

[0038] Optionally, a hole 102 is provided at the rear side of the first drawer 100. In this way, generally, the rear side of the refrigerator is the main source of cold energy, and there is no risk of cold energy leakage at the rear side. Therefore, the hole 102 is provided at the rear side of the first drawer 100, so that cold air can better enter the first drawer 100, and the first drawer 100 is cooled, so that the items can be quickly cooled after being placed, and the temperature fluctuation caused by the long-term inability to cool the items after being placed is reduced, and the temperature in the first drawer 100 is kept stable.

[0039] Optionally, a first lighting lamp is provided in the first drawer 100, and a second lighting lamp is provided in the second drawer 200. In this way, since the first drawer 100 and the second drawer 200 are detachable structures, lighting lamps are provided in the first drawer 100 and the second drawer 200 respectively, which can better illuminate the inside thereof, and facilitate users to store and retrieve items in a dark environment.

[0040] Optionally, the combined drawer further includes: a light control component, which is connected to both the first illuminating light and the second illuminating light, and is used to control the first illuminating light and the second illuminating light to be turned on simultaneously when the second drawer 200 is drawn out. In this way, when the second drawer 200 is drawn out, the illuminating lights in the first drawer 100 and the second drawer 200 are controlled to be turned on, which not only facilitates the user to access the items in the second drawer 200, but also helps the user to better see whether the items he needs are in the first drawer 100 with the help of the first illuminating light when there are no items he needs in the second drawer 200, thereby greatly improving the convenience of use for the user.

[0041] Optionally, the sliding assembly 400 includes: a sliding fixing seat 401 and a sliding block 402. The sliding fixing seat 401 is partially fixedly installed on the side of the first drawer 100, and the remaining part extends to the side of the second drawer 200, and the part extending to the side of the second drawer 200 is provided with a sliding groove 403; the sliding block 402 is fixedly arranged on the side of the second drawer 200, and the sliding block 402 is limited to slide in the sliding groove 403. In this way, the sliding fixing seat 401 is directly fixed on the side of the first drawer 100, the position of the sliding fixing seat 401 is fixed, and the stability of the sliding fixing seat 401 is improved. At the same time, the slider 402 is set on the second drawer 200, so that the slider 402 can slide along the slide groove 403 on the sliding fixing seat 401, thereby limiting the sliding of the second drawer 200, so that the second drawer 200 can slide back and forth relative to the first drawer 100, and the stability of the sliding connection between the two is improved. In addition, the sliding fixing seat 401 is connected to the first drawer 100, so that the overall sliding assembly 400 can have a higher load-bearing effect, so that the second drawer 200 can be completely pulled out of the refrigerator, which is more convenient for users to store and retrieve items in the second drawer 200.

[0042] Optionally, the sliding fixing seat 401 is a solid bar structure, one half of which is fixedly arranged on the side of the first drawer 100 by fixing screws, and the other half is provided with a slide groove 403. In this way, the stability of the connection between the sliding fixing seat 401 and the first drawer 100 can be maintained, thereby improving the load-bearing capacity of the sliding fixing seat 401, which is conducive to maintaining the stability of the second drawer 200 after being pulled out, and when the sliding fixing seat 401 has sufficient load-bearing capacity, it can ensure that the second drawer 200 is pulled out a sufficient distance, thereby improving the convenience of users to take out items.

[0043] Optionally, the sliding fixing seat 401 is a strip structure, and the slide groove 403 runs through the entire sliding fixing seat 401, and the width of the sliding fixing seat 401 is greater than twice the width of the slide groove 403. In this way, the slide groove 403 and the slider 402 are kept at a sufficient length, which is conducive to pulling out the second drawer 200 a sufficient distance so that it can be completely separated from the interior of the refrigerator, further improving the convenience of users in accessing items in the second drawer 200, and setting the width of the sliding fixing seat 401 to be wide enough can improve the stability of the fixing between it and the first drawer 100, maintain the bearing capacity of the sliding seat, and avoid damage to the sliding fixing seat 401 caused by the pressure of the weight of the second drawer 200.

[0044] Optionally, the slider 402 is a strip structure with the same length as the slide groove 403. In this way, a sufficient contact area is maintained between the slider 402 and the slide groove 403, and the stability of the connection between the two is improved. On the one hand, the distance that the second drawer 200 can be drawn out can be extended, and on the other hand, the load-bearing capacity of the combination of the sliding fixing seat 401 and the slider 402 can be maintained, and the stability of the second drawer 200 can be improved.

[0045] Optionally, a limiting stopper is provided at the front end of the slide groove 403. In this way, the sliding of the slider 402 can be limited, so as to prevent the slider 402 from being separated from the slide groove 403 and maintain the stability of the sliding between the two.

[0046] Optionally, the locking mechanism 300 includes: a locking link 301 and a limiting rod 302. The locking link 301 is rotatably connected to the side of the second drawer 200 through a rotating shaft 303, and a limiting groove 304 is provided on the portion of the locking link 301 extending to the side of the first drawer 100; the limiting rod 302 is fixedly arranged on the first drawer 100, and can be adapted to be combined or separated with the limiting groove 304. In this way, by rotatably connecting the side of the locking link 301 with the side of the second drawer 200, one end of the locking link 301 can be rotated, and then by controlling the rotation of the locking link 301, the limiting groove 304 on the locking link 301 can be combined or separated relative to the limiting rod 302. When the limiting groove and the limiting rod 302 are combined, the first drawer 100 and the second drawer 200 can be locked so that the two form a whole and can be pulled together. When the limiting groove and the limiting rod 302 are separated, the second drawer 200 can be pulled out separately relative to the first drawer 100, and then the use state of the first drawer 100 and the second drawer 200 can be selected according to the user's needs. When the first drawer 100 is not needed, the second drawer 200 can be pulled out separately to keep the first drawer 100 always in the depth of the refrigerator, reduce the loss of temperature inside the first drawer 100, improve the stability of its internal storage environment, and reduce overall energy consumption.

[0047] Optionally, the connection point between the locking link 301 and the side wall of the second drawer 200 is located in the area near the front third of the length of the side wall of the second drawer 200. In this way, when the locking link 301 rotates, the displacement of the end of the locking link 301 toward the first drawer 100 is greater than the end of the locking link 301 toward the second drawer 200, so that the user can press one end of the locking link 301 with a small stroke to cause the other end of the locking link 301 to have a larger displacement, so that the limiting groove 304 at the other end of the locking link 301 is easily separated from the limiting rod 302, thereby improving the convenience of use.

[0048] Optionally, the limiting groove 304 is a groove provided on the upper side of the locking link 301, and the depth of the groove is greater than or equal to the diameter of the limiting rod 302. In this way, the limiting groove 304 can wrap the limiting rod 302 more stably, improve the stability of the connection between the two, and avoid the limiting groove 304 and the limiting rod 302 automatically separating when subjected to lateral pulling force, which affects the user's experience.

[0049] Optionally, the rear part of the upper side of the locking link 301 located at the limiting groove 304 is an inclined surface 305, and the inclination angle of the inclined surface 305 is gradually inclined downward from the limiting groove 304. In this way, after the second drawer 200 is pulled out, the lowest end of the inclined surface 305 of the locking link 301 can be opposite to the limiting rod 302, so that the locking link 301 can be reset to the state where it locks the first drawer 100 and the second drawer 200, which is convenient for reducing the pressure on the locking link 301 after the second drawer 200 is pulled out, and its service life is improved. In addition, when the second drawer 200 is pushed in, under the action of the inclined surface 305, the limiting rod 302 can automatically slide into the limiting groove 304, and the first drawer 100 and the second drawer 200 can be automatically locked without user operation, thereby improving the convenience of use.

[0050] Optionally, the limiting rod 302 is a cylindrical protrusion fixedly arranged on the side wall of the first drawer 100. In this way, the cylindrical protrusion is more convenient for it to enter and exit the limiting groove 304, thereby improving the smoothness of the locking mechanism 300 to lock or unlock the first drawer 100 and the second drawer 200.

[0051] Optionally, the bottom of the limiting groove 304 is a semicircular groove that matches the shape of the limiting rod 302, and the upper side has a straight side wall. The bottom of the limiting groove 304 is a semicircular groove, which can better match the structure of the limiting rod 302, and the upper side is provided with a straight side wall, which can limit the limiting rod 302, prevent the limiting rod 302 from automatically detaching from the limiting groove 304, and improve the stability of use.

[0052] Optionally, a handle groove 500 is provided at the front side of the second drawer 200, and one end of the locking link 301 extends into the handle groove 500. By pressing the locking link 301 located in the handle groove 500, the other end of the locking link 301 can be moved in the opposite direction to the end. In this way, the handle groove 500 is provided at the front side of the second drawer 200, and the second drawer 200 can be pulled out through the handle groove 500. At the same time, one end of the locking link 301 is extended into the handle groove 500. When the user uses the handle groove 500, the user can choose whether to press the locking link 301, thereby controlling whether the first drawer 100 and the second drawer 200 are locked, thereby enabling the user to more flexibly and conveniently control the withdrawal method of the first drawer 100 and the second drawer 200, thereby improving the convenience of use.

[0053] Optionally, the handle groove 500 is disposed at the front side of the second drawer 200 and opens downward, and is an integral structure with the second drawer 200. In this way, the handle groove 500 opening downward facilitates the user to open the second drawer 200, and can also hide the internal structure of the handle groove 500.

[0054] Optionally, a pressing handle 501 is provided in the handle groove 500, and one end of the locking link 301 extending into the handle groove 500 is fixedly connected to the pressing handle 501. In this way, by providing the pressing handle 501 in the handle groove 500 and fixedly connected to one end of the locking link 301, it is convenient for the user to control the rotation of the locking link 301 by pressing the pressing handle 501, so that the user can control the rotation of the locking link 301 at any position in the handle groove 500, thereby improving the convenience of controlling the withdrawal method of the first drawer 100 and the second drawer 200.

[0055] Optionally, the pressing handle 501 is a long strip structure, which runs through both ends of the handle groove 500, and the locking rod 301 is provided with two ends, which are respectively arranged on both sides of the second drawer 200 and respectively connected to both ends of the pressing handle 501. In this way, the balance of both ends of the pressing handle 501 can be maintained, and pressure can be applied to the two locking rods 301 simultaneously.

[0056] Optionally, a non-slip cushion is provided on the lower side of the pressing handle 501. In this way, the comfort of the user when using the pressing handle 501 can be improved.

[0057] Optionally, the pressing handle 501 is located in the middle of the depth of the handle groove 500. In this way, the upper side of the pressing handle 501 has a movable space, and the lower side has a space for placing the user's hand, so that the user can use the handle groove 500 alone without using the pressing handle 501, thereby improving the convenience of use for the user.

[0058] Optionally, an anti-slip strip is provided near the lower side of the inner wall of the handle groove 500. In this way, when the user uses the handle groove 500 alone, the friction between the hand and the handle groove 500 is increased, which is more convenient for the user to use and prevents the hand from slipping.

[0059] Optionally, the push handle 501 is connected to the front side wall of the first drawer 100 through the elastic member 600. In this way, the push handle 501 can be reset by the elastic force of the elastic member 600, thereby driving the locking link 301 to reset. When the second drawer 200 is pushed back, the first drawer 100 and the second drawer 200 can be automatically locked under the action of the locking link 301 being reset, thereby maintaining the stability of the connection between the first drawer 100 and the second drawer 200.

[0060] Optionally, the elastic member 600 is a tension spring, and a fixing protrusion 601 is provided on the front side of the first drawer 100 below the pressing handle 501, and the tension spring is provided between the pressing handle 501 and the fixing protrusion 601. In this way, by using the tension spring to apply elastic force to the pressing handle 501 from the bottom, the space occupied by the thrust spring on the top of the pressing handle 501 can be avoided, making the overall space structure more compact.

[0061] Optionally, there are multiple elastic members 600, and the multiple elastic members 600 are symmetrically distributed at both ends of the center line of the pressing handle 501.

[0062] Optionally, the locking link 301 is provided with an upward limiting hook 306 at one end extending to the side of the first drawer 100. In this way, when the second drawer 200 is separated from the first drawer 100 and drawn out separately, the locking link 301 moves with the second drawer 200. When the end of the locking link 301 moves to the limiting rod 302, the limiting hook 306 provided at the end thereof can hook the limiting rod 302, thereby limiting the movement of the second drawer 200, and preventing the locking link 301 from being separated from the limiting rod 302, causing the locking rod to be unable to reset when it is subsequently pushed back with the second drawer 200, thereby affecting the normal locking between the first drawer 100 and the second drawer 200.

[0063] Optionally, the height of the limit hook 306 is sufficient so that it cannot bypass the limit rod 302 when it is at the lowest point of its range of motion. In this way, the limit hook 306 is prevented from being separated from the limit rod 302, which can play a better limiting role.

[0064] Optionally, the left and right sides of the first drawer 100 are further provided with slide rails 103 for sliding connection with the installation position. In this way, the first drawer 100 can be slidably connected, and is slidably connected with the installation position through the slide rails 103, and the second drawer 200 is slidably connected with the first drawer 100 through the sliding assembly 400. The two sets of sliding connection structures are adopted, so that the second drawer 200 can be completely separated from the interior of the refrigerator, which can improve the convenience of users to take out items in the second drawer 200.

[0065] Optionally, the slide rail 103 is a strip-shaped structure protruding relative to the side wall of the first drawer 100, and the protruding thickness of the slide rail 103 is greater than the thickness of the sliding assembly 400 and the locking mechanism 300. In this way, when the first drawer 100 is slidably connected to its installation position through the slide rail 103, the sliding assembly 400 and the locking mechanism 300 can have enough installation space, avoiding collision and friction between the sliding assembly 400 and the locking mechanism 300 and their installation positions, thereby improving the convenience between the two.

[0066] Optionally, a damping structure is provided on the slide rail 103 so that the sliding damping of the slide rail 103 is greater than the sliding damping of the sliding assembly 400. In this way, since the second drawer 200 is slidably connected to the first drawer 200, the first drawer 100 will also be subjected to a certain pulling force during the process of pulling out the second drawer 200. Therefore, a damping structure is provided on the slide rail 103 slidably installed on the first drawer 100 to increase the force required for the first drawer 100 to slide, thereby preventing the first drawer 100 from changing position as the second drawer 200 is pulled, maintaining the stability of the position of the first drawer 100, and further preventing the internal space from generating airflow during the pulling process, causing airflow exchange with the external ring, resulting in the loss of internal temperature, which can maximize the stability of the internal storage environment of the first drawer 100, reduce temperature loss, and save more energy.

[0067] Optionally, the damping structure is a rubber layer disposed on the slide rail 103. In this way, by disposing the rubber layer, the high friction of the rubber layer can be utilized to play a certain damping role, and the wear-resistant property of the rubber can be utilized to improve the overall wear-resistant effect.

[0068] Combination Figure 7 As shown, in some other optional embodiments, the combined drawer further includes: a third drawer 700, which is arranged at the rear side of the first drawer 100, wherein the locking mechanism 300 includes two gears, wherein the first gear can control the locking or unlocking between the first drawer 100 and the third drawer 700, and the second gear can control the locking or unlocking between the first drawer 100 and the second drawer 200. In this way, the drawer can be partitioned more finely, and the third drawer 700 located at the innermost side is used to store some items that need to be stored for a long time and are used very infrequently, thereby improving the flexibility of the overall use of the drawer.

[0069] Optionally, the locking mechanism 300 includes: a locking link 301 and a limiting rod 302, the locking link 301 is rotatably connected to the side wall of the second drawer 200, wherein the limiting rod 302 includes a first limiting rod 307 and a second limiting rod 308, the first limiting rod 307 is arranged on the side of the first drawer 100, and the second limiting rod 308 is arranged on the third drawer 700, and the locking link 301 is provided with a first limiting groove 309 corresponding to the first limiting rod 307 and a second limiting groove 310 corresponding to the second limiting rod 308. When the locking link 301 is rotated, the displacement of the locking link 301 is greater as it is closer to the rear end. Therefore, when the locking link 301 is rotated, the second limit rod 308 on the third drawer 700 is first disengaged. At this time, the first drawer 100 and the third drawer 700 can be unlocked, but the lock between the first drawer 100 and the third drawer 700 is not unlocked. At this time, the first drawer 100 and the second drawer 200 can be pulled out as a whole. Then, as the locking link 301 is further rotated, the first limit rod 307 on the first drawer 100 is also separated, and the lock between the second drawer 200 and the first drawer 100 is unlocked. At this time, the second drawer 200 can be pulled out separately. The user can control the rotation angle of the locking link 301, and then control the withdrawal form of the first drawer 100, the second drawer 200 and the third drawer 700 to meet the different usage requirements of the user. In addition, the same locking mechanism can be used to achieve the locking and unlocking relationship between the three drawers. The structure is simple, the cost is low, and the use is more convenient.

[0070] Optionally, the locking link 301 extends to the front side of the second drawer 200, and there is a raised stop rib between the locking link 301 and the second drawer 200. The raised stop rib has a certain elasticity, and can pass through the raised stop rib when the pressure on the locking link 301 is greater than the set pressure. In this way, the raised stop rib is used to assist the user in controlling the rotation angle of the locking link 301. When the user presses one end of the locking link 301 and feels the resistance brought by its contact with the raised stop rib, it means that the first drawer 100 and the third drawer 700 are separated at this time. The user can choose to pull out the first drawer 100 and the second drawer 200 together. The user can also choose to use a little force to make the locking link 301 pass through the raised stop rib, so that the second drawer 200 is also separated from the first drawer 100, and then the second drawer 200 is pulled out alone, which is convenient for the user to control the form of drawing out the drawer and improve the convenience of user use.

[0071] An embodiment of the present disclosure provides a refrigerator, comprising a combination drawer according to any one of the above embodiments.

[0072] The refrigerator provided by the embodiment of the present disclosure is provided with the above-mentioned combined drawer, and the first drawer 100 and the second drawer 200 are arranged front to back, and the locking or separation between the first drawer 100 and the second drawer 200 is controlled by a locking mechanism, wherein the second drawer 200 located at the front side is used to store some items that need to be taken frequently, and the first drawer 100 is used to store some items that are less frequently taken. When the user uses it, the locking mechanism can be used to unlock the second drawer 200 so that the second drawer 200 can be pulled out separately. At this time, the first drawer 100 maintains its position inside the refrigerator unchanged, and the second drawer 200 is pulled out separately, so that the first drawer 100 can maintain its internal stability without moving, avoid air flow activity in the first drawer 100, which causes leakage of cold air inside it, and then maintain the temperature balance in the first drawer 100 and reduce its temperature loss. On the one hand, it can provide a more stable storage effect, and on the other hand, it can reduce the energy consumption of the refrigerator by reducing temperature loss.
