First introduce the embedded refrigerator device that the present invention also proposes,

In the embodiment of the present invention, as shown in Figures 1 to 3, the embedded refrigerator device includes:

The cabinet includes a cabinet body (not shown) and a cabinet door 100, the cabinet body has a cavity (not shown) that is open on one side, and the cabinet door 100 is used to close or open the cavity;

The refrigerator is located in the cavity, and the refrigerator includes a box body (not shown) and a door body 200 pivotally connected with the box body, the door body 200 is opposite to the cabinet door 100; and

The door connection device of the built-in refrigerator, the door connection device connects the cabinet door 100 and the door body 200 to open and close the cabinet door 100 and the door body 200 at the same time, referring to Figures 4 to 8, the door connection device includes:

The guide rail 1 includes a strip-shaped fixing part 11 and a chute structure 12 connected with the fixing part 11. The fixing part 11 is used to fix the door body 200 of the refrigerator. The chute structure 12 extends along the length direction of the fixing part 11 and is connected The fixed parts 11 are arranged in parallel;

The slider 2 includes a mounting portion 21 and a sliding buckle portion 22 protruding from one end of the mounting portion 21. The mounting portion 21 is used to install with the cabinet door 100 of the cabinet. The sliding buckle portion 22 cooperates with the chute structure 12 to limit the door body 200 and The cabinet door 100 moves in a direction away from each other, and the slider part 22 and the chute structure 12 are slidably fitted along the first direction consistent with the length direction of the fixed part 11; the size of the slider 2 in the first direction is smaller than that of the guide rail 1 Dimensions in the first direction, and when the door body 200 and the cabinet door 100 are at the maximum open position, the mounting portion 21 protrudes from the end of the guide rail 1 in the first direction.

In this embodiment, it should be noted that the cabinet 100 mentioned in the present invention should be understood in a broad sense, that is, it can be a separate cabinet, and it can also include an opening inside the wall to form an accommodation space inside, but it is not limited to this. As shown in the figure, when the door body 200 and the cabinet door 100 are at the maximum open position, the mounting portion 21 protrudes from the side of the door body 200 away from the hinge of the door body 200 in the first direction.

For the specific structure of the door connecting device used in the embedded refrigerator of this embodiment, refer to the following embodiments. Since this embedded refrigerator device adopts all the technical solutions of all the following embodiments, it has at least the technical solutions of the following embodiments All the beneficial effects brought about will not be described in detail here.

Further, referring to Fig. 2, Fig. 7, Fig. 9 and Fig. 13, the door body 200 includes a panel 201 opposite to the cabinet door 100, the guide rail 1 is fixed on the side of the panel 201 away from the cabinet door 100, and the panel 201 is provided with a The chute structure 12 corresponds to the channel 202;

Please refer to Figure 14 and Figure 15 together, the chute structure 12 runs through the side of the guide rail 1 away from the panel 201, the door connection device also includes a second cover 4, and the second cover 4 is used to cover the chute structure 12 away from the cabinet One side of the door 100.

In this embodiment, the guide rail 1 can be "pre-embedded" in the door body 200, and the guide rail 1 can further enhance the fixing strength by combining the guide rail 1 with the foam material of the refrigerator door body 200. At the same time, compared with fixing the guide rail 1 to the door body On the outer side of 200, the integration of guide rail 1 and door body 200 is higher. It can be understood that when the panel 201 is a sheet metal part, the guide rail 1 can also be fixed to the panel 201 by welding. When assembling, the sliding buckle part 22 of the slider 2 is inserted into the chute structure 12 through the channel 202 .

In order to facilitate the production of the chute structure 12 through the front and back sides of the guide rail 1, since the guide rail 1 is pre-embedded in the door body 200, if the foam material leaks into the chute structure 12, it will hinder the buckle part 22 of the slider 2. By setting the second cover 4 to seal, the foam material can be prevented from entering the chute structure 12 . Preferably, the cover is detachably fixed to the guide rail 1 .

Further, both ends of the groove 121 are closed, so that the sliding groove 122 can also limit the slider 2 in the first direction. Specifically, the chute structure 12 includes a groove 121 located on the side of the guide rail 1 facing the cabinet door 100. The groove 121 includes a bottom wall facing the cabinet door 100 and two side walls connected to two opposite sides of the bottom wall. The structure 12 further includes slide grooves 122 respectively disposed on the two side walls. A second positioning groove 14 for accommodating the edge of the second cover 4 is provided at the connection between the groove wall surface of the two sliding grooves 122 and the side of the guide rail 1 facing away from the panel 201, and the edge of the second cover 4 is fitted in the second positioning groove 14 , the bottom of the second positioning groove 14 is provided with a second clamping hole, and the side of the second cover 4 facing the guide rail 1 is provided with a second buckle 41 adapted to the second positioning groove 14 .

Further, a step-shaped concave portion 15 is provided at the connection between the side of the guide rail 1 facing the cabinet door 100 and the side of the adjacent panel 201, one step surface of the step-shaped concave portion 15 is attached to the inner surface of the panel 201, and the other step surface is in contact with the channel. 202 edge abutment. In this way, the sliding rail can be positioned and limited by the cooperation between the stepped recess 15 and the edge of the channel 202 of the panel 201 .

Further, the fixing part 11 includes a slot 16 disposed on a side of the guide rail 1 adjacent to the panel 201 , the slot 16 is used to fill the foam material of the door body 200 . In this way, on the one hand, the combination of the guide rail 1 and the foam material is tighter; on the other hand, the material used for the guide rail 1 can be reduced, so that the wall thickness of each part of the guide rail 1 is more uniform, and thus easier to produce.

The door connecting device for a built-in refrigerator proposed by the present invention will be introduced in detail below.

In the embodiment of the present invention, the built-in refrigerator is accommodated in the cabinet, as shown in Fig. 2, Fig. 7, Fig. 9 and Fig. 13, the door connecting device of the built-in refrigerator, the door connecting device includes:
