[0036] In built-in furniture, a refrigeration device can be embedded in a cabinet, and the cabinet door can be used to cover the cabinet body of the cabinet, so as to combine the outer surface of the cabinet with the home decoration style. The refrigeration device can be embedded in the cabinet. Among them, the door of the refrigeration device is rotatably connected to the box body of the refrigeration device. The door of the refrigeration device can be used to cover the accommodation space inside the box body, and the cabinet door is rotatably connected to the cabinet body. However, as the door of the refrigeration device is opened, the cabinet door is prone to interference and collision with the side wall of the cabinet, resulting in a poor use experience of the built-in refrigerator. Therefore, the present application proposes a sliding door mechanism for a built-in refrigerator to solve the defect that the built-in refrigerator is prone to interference with the side wall of the cabinet during the door opening process, affecting the use experience.

[0037] It should be noted that the door connection device of the built-in refrigerator proposed in the present application can be used for built-in refrigerators, and can also be used for built-in freezers, built-in ice makers, etc., or the doors of other rotatably connected refrigeration devices.

[0038] The following combines Figure 1 Describe the door connection device and refrigeration device of the built-in refrigerator of the present application.

[0039] The door connection device of the built-in refrigerator according to the first aspect embodiment of the present utility model includes a guide rail 1, a first rack 2, a gear 3, a second rack 4 and a connecting rod 5. The guide rail 1 is provided with parallel first slide rails 11 and second slide rails 12; the first rack 2 is slidably arranged on the first slide rail 11; the gear 3 is arranged on the guide rail 1 and is located between the first slide rail 11 and the second slide rail 12, and the first rack 2 meshes with the gear 3; the second rack 4 is slidably arranged on the second slide rail 12, the second rack 4 meshes with the gear 3, and the teeth of the first rack 2 and the teeth of the second rack 4 are arranged oppositely. The second rack 4 is used to connect the cabinet door; one end of the connecting rod 5 is rotatably connected to the first rack 2, and the other end of the connecting rod 5 is used to be rotatably connected to the box body of the refrigerator. It should be noted that here the slide rail can be in the structural form of a chute or a slide bar, which is not limited here as long as it can enable the corresponding structure to slide on the slide rail.

[0040] During the process of opening the refrigerator door, the connecting rod 5 pushes the first rack 2 to move along the first slide rail 11, drives the gear 3 to rotate, and the second rack 4 moves along the second slide rail 12 in the direction opposite to the first rack 2 to drive the cabinet door to move towards the door opening side of the refrigerator door.

[0041] The door connection device of the built-in refrigerator according to the embodiment of the present utility model realizes the relative sliding of the first rack 2 and the second rack 4 through double slide rails. That is, when the first rack 2 moves on the first slide rail 11, through the transmission of the gear 3, the second rack 4 is driven to move along the second slide rail 12. Since the first slide rail 11 and the second slide rail 12 are parallel, and the teeth of the first rack 2 and the teeth of the second rack 4 are arranged oppositely, the first rack 2 and the second rack 4 move in opposite directions. The connecting rod 5 connects the box body and the first rack 2. When the refrigerator door is opened, the connecting rod 5 can rotate with the door of the box body relative to the box body, thereby pushing the first rack 2 to move, and further driving the second rack 4 to drive the cabinet door to move towards the opening side of the box door. In this way, the interference problem between the built-in refrigerator door body and the cabinet during the opening and closing process can be avoided, and the occurrence of wear, jamming and other situations can be reduced.

[0042] In this embodiment, the guide rail 1 is installed on the top of the door of the refrigerator to facilitate the connection between the connecting rod 5 and the box body. The guide rail 1 is provided with a relatively arranged first slide rail 11 and a second slide rail 12. Exemplarily, the guide rail 1 is a flat plate structure, and the parallel first slide rail 11 and second slide rail 12 are protruded on the surface of the flat plate. The tracks of the first slide rail 11 and the second slide rail 12 are arranged oppositely, so that the teeth of the first rack 2 and the second rack 4 are arranged oppositely after installation. It can be understood that the gear 3 is clamped between the first rack 2 and the second rack 4. When the gear 3 rotates, the first rack 2 and the second rack 4 move in opposite directions.

[0043] According to an embodiment of the present utility model, the connecting rod 5 includes a first section 51 and a second section 52 connected to each other. The first section 51 is used to connect to the box body of the refrigerator, and the second section 52 is perpendicular to the first rack 2 and connected to the first rack 2. It can be understood that the second section 52 is perpendicular to the first rack 2, so that when the second section 52 pushes the first rack 2 to slide along the first slide rail 11, whether the first rack 2 is pushed to move to the left or the right, the force is relatively uniform. Compared with the second section 52 being obliquely connected to the first rack 2, the perpendicular connection is beneficial to balancing the forces on both sides of the second section 52 when driving the first rack 2 to move in different directions and extending its service life. At the same time, by dividing the connecting rod 5 into the first section 51 and the second section 52, when the second section 52 is perpendicularly connected to the first rack 2, the first section 51 can connect the second section 52 and the box body, and the connection with the box body can be adjusted by the connection angle between the first section 51 and the second section 52. Optionally, the first section 51 and the second section 52 can be an integrally formed structure, or can be connected by welding, bonding, clamping or threaded connection, etc., which is not limited here. It should be noted that here perpendicularity allows a deviation of plus or minus 10 degrees, and it is not limited that the second section 52 and the first rack 2 form a 90-degree angle, and the certain error caused by its processing should also be within the protection scope of this application.

[0044] According to an embodiment of the present utility model, the first section 51 and the second section 52 are connected at an obtuse angle. Thus, when the first rack 2 is located at the middle section of the top of the cabinet door, and the second section 52 is vertically connected to the first rack 2, the first rack 2 can extend obliquely to the corner of the cabinet, reducing the occupation of the middle space of the refrigerator to avoid interfering with the user.

[0045] According to an embodiment of the present utility model, the length of the first section 51 is longer than the length of the second section 52. Optionally, the width of the first section 51 is wider than the width of the second section 52. It can be understood that in order to be vertically connected to the first rack 2, the length and width of the second section 52 can be set relatively small, while the first section 51 mainly plays a role in supporting rotation, and its length and width can be set relatively large, so as to ensure its own strength and achieve a better support effect, that is, the length and width of the first section 51 can be set to be greater than the length and width of the second section 52 at the same time.

[0046] According to an embodiment of the present utility model, the length of the first rack 2 is equal to the length of the second rack 4. It can be understood that since the second rack 4 moves driven by the gear 3 on the basis of the movement of the first rack 2, the moving distance of the first rack 2 is equal to the moving distance of the second rack 4. Setting the lengths of the first rack 2 and the second rack 4 to be equal can avoid the situation where the displacement of the second rack 4 exceeds the meshing range with the gear 3 when the first rack 2 is longer than the second rack 4. Of course, in other embodiments, the length of the second rack 4 can also be set to be longer than the length of the first rack 2 to reserve the length for the second rack 4 to displace relative to the first rack 2.

[0047] According to an embodiment of the present utility model, a first mounting block 21 is provided on the side of the first rack 2 facing away from the second rack 4, and the first mounting block 21 is connected to the connecting rod 5; Exemplarily, the first mounting block 21 facilitates the rotational connection with the connecting rod 5. The first mounting block 21 is provided with a first mounting hole, and the connecting rod 5 can be rotated and connected to the first mounting block 21 by passing a rotating shaft through the connecting rod 5 and through the first mounting hole. Optionally, the first mounting block 21 and the first rack 2 are of an integrally formed structure, saving the installation steps and ensuring the connection strength. The connecting rod 5 pushes the first rack 2 to slide through the first mounting block 21, avoiding the direct connection between the connecting rod 5 and the first rack 2, thereby avoiding the situation that the first rack 2 is prone to deformation after the connecting rod 5 pushes the first rack 2 for a long time, and the service life of the first rack 2 is longer.

[0048] In an embodiment, a second mounting block 41 is provided on the side of the second rack 4 facing away from the first rack 2, and the second mounting block 41 is used for connecting to the cabinet door. It can be understood that the second mounting block 41 is provided with a second mounting hole to facilitate the connection between the second rack 4 and the cabinet door. Exemplarily, the cabinet door can be fixedly connected to the second mounting block 41 through structures such as bolts, so that the cabinet door moves along with the movement of the second rack 4.

[0049] According to an embodiment of the present utility model, the first rack 2 is provided with a first roller, and the first rack 2 moves along the first slide rail 11 through the first roller. Exemplarily, a first roller is installed on one side surface of the first rack 2, and the first roller rolls on the first slide rail 11. A plurality of first rollers can be arranged in the length direction of the first rack 2 to roll and move the first rack 2 on the first slide rail 11, which is beneficial to reducing the friction between the first rack 2 and the first slide rail 11 and facilitating the sliding of the first rack 2. In this way, it is more labor-saving for the connecting rod 5 to push the first rack 2 to slide on the first slide rail 11, the sliding of the first rack 2 is smoother, and jamming is reduced.

[0050] According to an embodiment of the present utility model, the second rack 4 is provided with a second roller, and the second rack 4 moves along the second slide rail 12 through the second roller. Exemplarily, a second roller is installed on one side surface of the second rack 4, and the second roller rolls on the second slide rail 12. A plurality of second rollers can be arranged in the length direction of the second rack 4 to roll and move the second rack 4 on the second slide rail 12, which is beneficial to reducing the friction between the second rack 4 and the second slide rail 12 and facilitating the sliding of the second rack 4. In this way, it is more labor-saving for the first rack 2 to drive and push the second rack 4 to slide on the second slide rail 12 through the gear 3, the sliding of the second rack 4 is smoother, and jamming is reduced.

[0051] According to an embodiment of the present utility model, the guide rail 1 is provided with a limiting member; the limiting member is arranged on the first slide rail 11, and the limiting member is used for stopping and limiting the first rack 2; in one embodiment, the limiting member is arranged on the second slide rail 12, and the limiting member is used for stopping and limiting the second rack 4. It can be understood that the limiting members can be respectively arranged at both ends of the guide rail 1 to stop and limit the first rack 2 and the second rack 4 to slide within a specific area of the first slide rail 11 and the second slide rail 12 to avoid situations such as derailment. Optionally, the limiting members can be arranged at both ends of the first slide rail 11. Since the second rack 4 moves when the first rack 2 moves, it is only necessary to limit the displacement range of the first rack 2 to save the installation cost. In other embodiments, the limiting members can also be arranged at both ends of the second slide rail 12. Of course, they can also be arranged at both ends of the first slide rail 11 and the second slide rail 12 at the same time, which is not limited herein.

[0052] The refrigeration device according to the second aspect embodiment of the present utility model includes a box body, a box door, a cabinet door, and the door body connection device of the above-mentioned built-in refrigerator. The box door is rotatably connected to the box body. The cabinet door is slidably arranged on the box door. One end of the connecting rod 5 is connected to the box body. The guide rail 1 is arranged on the box door, specifically can be installed on the top of the box door. The second rack 4 is connected to the cabinet door. The refrigeration device can be a refrigerator, or a freezer, an ice maker, such as an embedded freezer, an embedded ice maker, etc. It should be noted that the cabinet door and the refrigeration device are respectively manufactured by different manufacturers, and based on the user's selection, different models of refrigeration devices and cabinet doors will be assembled. The door body connection device of the built-in refrigerator in this application connects the box door and the cabinet door, enabling the cabinet door to slide relative to the box door. In this way, the cabinet door can be not rotatably connected to the side wall of the cabinet. For example, the cabinet door and the box door are connected by a slide rail, and the box door supports the cabinet door, and the cabinet door slides along the slide rail on the box door. In this way, the difficulty of production and manufacturing can be reduced, and at the same time, the difficulty of assembly is also reduced.
