[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0036] At present, the kitchen and dining room of a household house are generally separated by only one wall, and this wall is a non-load-bearing wall and can be modified. Existing refrigerators can generally only be used in one room. However, as the demand for refrigerator volume increases, the floor space occupied by the refrigerator also increases. In household use, refrigerators can usually only be placed in a fixed area, such as in the kitchen or dining room. If the refrigerator is placed in the kitchen, it is very convenient to take ingredients when cooking, but you need to go to the kitchen to take cold drinks, snacks and other items; if the refrigerator is placed in the dining room, it is relatively convenient to take cold drinks, snacks and other items, but it is inconvenient to take ingredients when cooking. Therefore, the present invention designs a refrigerator with front and rear doors placed on the walls of two adjacent rooms, embedded in the wall, reducing the usable area of ​​the refrigerator in a single room, and allowing both rooms to use the refrigerator, achieving the purpose of using one refrigerator in two rooms. This refrigerator's freezer compartment uses a drawer-style door opening and closing scheme. The front and rear doors are identical and share a single freezer drawer. A handle and connector are installed on the door. When the user opens the door, the handle is pulled open, rotating the connector until it engages the drawer, allowing the drawer to be pulled out of the freezer. The same mechanism operates on the other side. This structure ensures that items stored in the refrigerator near the other door are accessible from both door opening directions, providing convenient access.

[0037] like Figures 1 to 4 As shown, the present invention proposes a drawer mechanism, comprising: a housing 1, i.e., the main body of a refrigerator, with two openings on each side of the housing 1. Multiple drawers 2 are installed within the housing 1 for storing food. Each side opening of the housing 1 is provided with multiple drawer doors 3 that seal the opening and can be pulled outward. In other words, multiple drawer doors 3 can be provided on one side, each corresponding to at least one drawer 2, and together they seal the opening on that side to prevent cold air leakage. Each drawer door 3 is provided with a connector 4 and a handle 5. The handle 5 is mounted on the connector 4. Pulling the handle 5 rotates the connector 4, causing it to engage the drawer 2 inside the drawer door 3. Continuously pulling the handle 5 outward allows the drawer door 3 and the drawer 2 inside the drawer door 3 to be pulled out together. When the drawer door 3 is pushed back, the drawer 2 is directly pushed by the drawer door 3 until the drawer door 3 is flush with the side of the housing 1. When the drawer 2 needs to be pulled out on the other side, the handle 5 on the drawer door 3 on the other side is also pulled to pull out the drawer door 3 and the drawer 2 inside the drawer door 3 together through the connecting piece 4, completing the storage. When closing, the drawer door 3 is also directly pushed, so that the drawer door 3 pushes the drawer 2 to move and retract until the drawer door 3 is in contact with the side surface of the other side of the box body 1. The drawer structure is simple, easy to use, adopts a simple mechanical structure, can be reused many times, and has good durability.

[0038] The specific structural form of the connecting piece can be set in various ways, and as long as it is a connecting piece for connecting the drawer door and the drawer compartment, it is within the scope of protection of the present invention. A specific preferred embodiment is given below.

[0039] like Figures 2 to 4 As shown, the connecting member 4 is a rotating hook. When the handle 5 is pulled outward, the rotating hook automatically rotates and automatically engages the drawer 2. The connecting member 4 specifically includes a rotating block 41, a connecting handle 42, and a curved hook 43. The rotating block 41 is rotatably mounted inside the drawer door 3. The connecting handle 42 is connected to the upper curved surface of the rotating block 41. The end of the connecting handle 42 is fixed to the handle 5. When the handle 5 is pulled outward, the rotating block 41 is driven to rotate clockwise by the connecting handle 42. The curved hook 43 is connected to the lower curved surface of the rotating block 41. When the handle 5 is pulled outward and the connecting handle 42 swings to its maximum distance, the rotating block 41 rotates clockwise and drives the curved hook 43 to extend from the inner side of the drawer door 3 and engage the drawer 2. When the handle 5 is continued to be pulled out, the rotating block 41 does not rotate, but the curved hook 43 still engages the drawer 2, so that the drawer door 3 and the drawer 2 can be pulled out together.

[0040] like Figure 3 As shown, the structure corresponding to the installation of the above-mentioned connecting member 4 on the drawer door 3 is as follows: a first notch 31 is provided on the top of the drawer door 3, and a second movable cavity 32 is provided inside. The first notch 31 leads to the top surface and the outer side surface of the drawer door 3, that is, there are gaps on the top surface and the outer side surface to form a pocket-shaped groove; the second movable cavity 32 is also connected to the inner side surface of the drawer door 3, and the top of the second movable cavity 32 is connected to the bottom of the notch. A rotating block 41 is provided at the connection between the second movable cavity 32 and the notch. The rotating block 41 is rotatably installed at the connection between the second movable cavity 32 and the notch. The connecting handle 42 is installed at the first notch 31, and the bottom of the connecting handle 42 is connected to the rotating block 41. The hook 43 is installed in the second movable cavity 32, and the top of the hook 43 is connected to the rotating block 41. When the connecting handle 42 hits the inner wall a of the first notch 31, the handle 5 is pulled to the maximum distance, and the hook 43 is buckled into the drawer bucket 2.

[0041] A spring may be provided between the connecting handle 42 and the inner wall a, and the elasticity of the spring may cause the handle 5 on the connecting handle 42 to automatically rebound (causing the hook 43 to automatically return to its position), or the handle 5 may be rebounded by other means.

[0042] In addition, the top of the drawer door 3 is rounded, that is, the two sides of the first slot 31 are curved surfaces extending to the top surface of the drawer door 3, and the outer side of the handle 5 is curved and installed on the edge of the first slot 31. That is, if the user wants to pull the box door 6 outward, the best leverage point is to pull the position of the inner side of the handle 5, so as to avoid the user pulling out the drawer door 3 by other means while the drawer box 2 is not pulled out.

[0043] The specific structure of the drawer bucket 2 is as follows: the drawer bucket 2 is in the shape of a rectangular parallelepiped, with rounded corners on all sides and the bottom. A horizontal bent edge 21 is provided on the top of the drawer bucket 2, and a bayonet 21 is provided on the bottom surface of the bent edge 21 on the front and rear sides of the drawer bucket 2. In order to ensure the volume of the drawer bucket 2 as much as possible, bayonet 211 can be provided at the four corners of the bent edge 21 for cooperation with the bent hook 43.

[0044] The following is a preferred embodiment of the arrangement of the drawer boxes 2. There are many other specific ways of matching the drawer boxes 2 and the drawer doors 3. The drawer boxes 2 and the drawer doors 3 can correspond one to one, or multiple drawers 2 can correspond to one drawer door 3.

[0045] In this embodiment, Figure 4 、 5 As shown, two drawers 2 are arranged horizontally in the box body 1, and at least one drawer 2 is arranged vertically, specifically two in the figure. Each drawer door 3 covers two drawers 2 arranged horizontally. Three handles 5 are set horizontally on each drawer door 3. The handles 5 on both sides are respectively connected to a connecting piece 4, and the handle 5 in the middle is connected to two connecting pieces 4 at the same time. Pulling the left handle 5 can pull out the drawer door 3 and the drawer 2 on the left, pulling the right handle 5 can pull out the drawer door 3 and the drawer 2 on the right, and pulling the middle handle 5, because the middle handle 5 is connected to two connecting pieces 4 at the same time, can pull out the drawer door 3 and the left and right drawers 2 at the same time. By setting multiple handles 5 on the same drawer door 3, one drawer 2 can be pulled out separately, or two drawers 2 can be pulled out at the same time, which can prevent cold air leakage and improve the user experience.

[0046] In order to keep the handle 5 stable, the handles 5 on both sides are further provided with support members 7, which are spaced apart from the connecting member 4 of the handle 5. The support member 7 also includes a rotating block 41 and a connecting handle 42 (the functions of the rotating block 41 and the connecting handle 42 are exactly the same as those of the connecting member 4), but no hook 43 is provided, that is, the long and horizontally arranged handle 5 is connected to the connecting member 4 near the outer end for hooking the drawer bucket 2, and is connected to the support member 7 near the inner end, so that the structure of the handle 5 is stable and uniform force is ensured when it is pulled outward.

[0047] like Figure 5 、 6As shown, the specific connection method between the drawer 2 and the housing 1 can use a traditional drawer slide structure to achieve the sliding withdrawal and sliding push-back of the drawer. The present invention specifically provides an embodiment of a preferred specific connection method between the drawer 2 and the housing 1, specifically: the space within the housing 1 is divided into a plurality of drawer compartments 13 for mounting the drawer 2, each drawer compartment 13 is provided with support rails 23 on opposite sides, and the drawer 2 is provided with matching rails 22 corresponding to the support rails 23 on both sides. The support rails 23 and the matching rails 22 are both provided with a slot, and the support rails 23 and the matching rails 22 can be connected by a slider 25 with a block on both sides. Specifically, the blocks on both sides of the slider 25 are respectively inserted into the support rails 23 and the matching rails 22. Therefore, when the drawer 2 is pulled out of the drawer compartment 13, the matching rails 22 on the side of the drawer 2 can slide along the slider 25, and the slider 25 can also be driven to slide along the support rails 23.

[0048] like Figure 6 As shown, to improve the sliding reliability of the drawer 2, racks 24 are provided on opposite sides of the supporting rail 23 and the mating rail 22, and the slider 25 is provided with at least one gear 26 that mates with the rack 24. The gear 26 can be specifically provided by forming a hole in the slider 25 that connects the two opposite sides thereof, and placing the gear 26 within the hole. The edge of the gear 26 extends outside the slider 25 to mate with the racks 24 located on either side of the slider 25. The provision of the gear 26 makes the drawer 2 more reliable when sliding, and the slider 25 provides support when the drawer 2 is not being pulled.

[0049] Two guide rails 33 are vertically arranged on the inner side of the drawer door 3, and the inner side of the box body 1 (ie the inner wall of the drawer compartment 13 on the outer side) is provided with a guide rail slot, so that the drawer door 3 can be pulled out and pushed back.

[0050] like Figure 5 、 7 As shown, the present invention also proposes a refrigerator, including the above-mentioned drawer structure, that is, the box body 1 of the drawer structure is the box body 1 of the refrigerator. In a specific embodiment, the lower part of the box body 1 is a freezer compartment 11, and the upper part is a refrigerator compartment 12. The freezer compartment 11 is provided with a drawer bucket 2 and a drawer door 3 in the above-mentioned drawer structure, and the upper refrigerator compartment 12 is provided with multiple partitions 121 for separation. A drawer structure can also be provided in the upper refrigerator compartment 12, all of which are within the protection scope of the present invention.

[0051] Specifically, two opposite sides of the refrigerating chamber 12 in the upper portion of the housing 1 are provided with doors 6 (i.e., the structure of the doors 6 of the existing double-door refrigerator, which will not be described in detail).

[0052] As can be seen from the figure, the bottom surface of the box is provided with multiple supporting feet 9, the bottom of the box is used to install the compressor 8, a groove is provided on the right side of the bottom of the box, the compressor is installed in the groove, and is equipped with a compressor base plate 81 to ensure the stable position of the compressor 8. The side walls of the box are also provided with air ducts, heat exchangers and other components, which are not the focus of protection of the present invention and will not be described in detail.
