[0038] The present application will be described in detail below with reference to the embodiments shown in the drawings. However, the embodiments do not limit the present application, and the structural, method, or functional changes made by those skilled in the art based on the embodiments are included in the protection scope of the present application.

It can be understood that the terms of spatial relative positions can be intended to include different orientations other than those shown in the drawings, and should not be construed as limiting the claims. In addition, the descriptive word "horizontal" used herein is not completely equivalent to along the direction perpendicular to the direction of gravity, and allows a certain angle of inclination.

[0040] Referring to FIG. 1, the present application provides a household appliance device 1000, which includes an embedded household appliance 200 and a cabinet 300 for accommodating the embedded household appliance 200. In the present embodiment, the embedded household appliance 200 can be a refrigerator. The household appliance 200 includes a first door body 210 for opening or closing a cabinet, and the cabinet. The cabinet 300 includes a second door body 310 covering the first door body 210.

[0041] The household appliance device 1000 further includes a sliding connection device 100 for slidingly connecting the first door body 210 to the second door body 310.

[0042] The present application provides a door body assembly including the first door body 210, the second door body 310, and the sliding connection device 100. The door body assembly can include two sets of sliding connection devices 100 arranged at the top and bottom.

[0043] The connection of the first door body 210 of the embedded household appliance 200 to the cabinet can be achieved by a folding hinge or a rotating shaft hinge. When the first door body 210 is equipped with a rotating shaft hinge, the first door body 210 and the second door body 310 need to be arranged in a sliding connection, so that when the household appliance 200 is installed into the cabinet 300, the first door body 210 and the second door body 310 are allowed to rotate relative to each other to open or close the cabinet.

[0044] The sliding connection device 100 includes a first sliding member 10 and a second sliding member 20 in a sliding connection. The first sliding member 10 and the second sliding member 20 are arranged between the first door body 210 and the second door body 310, and when the second door body 310 is opened, the first door body 210 can be driven to open, thereby opening the cabinet of the household appliance 200.

[0045] Referring to FIGS. 2-4, in an embodiment, the sliding connection device 100 comprises an auxiliary positioning member 30 for assisting the positioning of the second sliding member 20 to the second door body, so that the second sliding member 20 can be fixed to a predetermined position of the second door body 310 to achieve smooth sliding between the first sliding member 10 and the second sliding member 20.

[0046] The first sliding member 10 comprises a fixed part 11 positioned to the first door body 210, a first sliding part 12 slidingly matched with the second sliding member 20, and an auxiliary positioning part 13 matched with the auxiliary positioning member 30. The auxiliary positioning between the first sliding member 10 and the second door body 310 realized by the auxiliary positioning member 30 can be removed under external force.

[0047] In the related art, after the auxiliary positioning member 30 is combined with the auxiliary positioning part 13 and the first door body is installed, it is usually difficult to remove the auxiliary positioning member 30 alone, so the auxiliary positioning part 13 and the first sliding part 12 are arranged separately, so that after installation, the auxiliary positioning member 30 is separated together with the auxiliary positioning part 13, without affecting the normal sliding between the door body assemblies; but the above inevitably causes material waste.

[0048] In the present application, the predetermined positioning function of the auxiliary positioning member 30 can be removed under external force, thereby releasing the auxiliary positioning between the first sliding member 10 and the second door body 310. On the one hand, the auxiliary positioning part 13 can be continuously retained, without wasting materials and increasing the strength of the original first sliding member 10; on the other hand, compared with separating and disassembling the auxiliary positioning part 13 and the auxiliary positioning member 30, in the present application, only external force is needed to remove the predetermined positioning connection, which is more simple and convenient.

[0049] In the first embodiment, the auxiliary positioning member 30 is double-sided tape, and the auxiliary positioning part 13 comprises a sticking groove 130 for sticking one side of the double-sided tape, and the other side of the double-sided tape is used to stick to the second door body 310.

[0050] Specifically, one side of the auxiliary positioning member 30 sticks to the first sliding member 10, and the other side sticks to the inner surface of the second door body 310, realizing the positioning and matching between the two. After the sliding connection device 100 is installed, since the adhesion between the auxiliary positioning member 30 and the second door body 310 is not particularly firm, only force needs to be applied to the second door body 310 to release the adhesion between the second door body 310 and the first sliding member 10, so that the second door body 310 can smoothly slide relative to the first sliding member 10, thereby ensuring the sliding function between the first door body 210 and the second door body 310.

[0051] In this embodiment, only the first sliding member 10 is needed to realize the positioning between the first door body 210 and the second door body 310, and the assembly process is simple; and after the positioning is completed, any component does not need to be separated and disassembled, and relative to the separated and disassembled auxiliary positioning part 13 and auxiliary positioning member 30, the adhesive of the double-sided adhesive tape is removed by force, which is more fast and convenient.

[0052] In combination with FIGS. 7-8, in the second embodiment, the auxiliary positioning member 30' is a hanging clamp, and the auxiliary positioning part 13' includes a slot 130' arranged along the height direction. The auxiliary positioning member 30 includes a positioning part 31' matched with the second door body, and a positioning wall 32' connected with the positioning part 31', which moves along the height direction relative to the auxiliary positioning part 13'. The positioning wall 32' is arranged with a plurality of tapered teeth 321', and the auxiliary positioning part 13' is arranged with a clamping tooth 131' matched with the tapered teeth 321'.

[0053] The positioning wall 32' is a vertical wall, the positioning wall 32' is parallel to the first sliding member 10, and the positioning part 31' is located at the top of the positioning wall 32'. When installed, the positioning wall 32' is inserted into the first sliding member 10 from top to bottom until the positioning part 31' is clamped and positioned on the second door body 310.

[0054] The positioning part 31' is arranged in an L shape, and is used to clamp the top of the second door body 310, so that the positioning and matching of the first sliding member 10 and the second door body 310 are realized.

[0055] The tapered teeth 321' are arranged on one side of the positioning wall 32' facing the first sliding member 10, so as to be matched with the clamping tooth 131' of the auxiliary positioning part 13'. The tapered teeth 321' and the clamping tooth 131' can be fixed or relatively moved.

[0056] When the sliding connection device 100 is installed, the auxiliary positioning member 30' can be separately forced to be removed from the slot 130', so as to remove the pre-positioning of the first sliding member 10 and the second door body 210, which is convenient and fast.

[0057] The auxiliary positioning part 13' is provided with an elastic wall 132', and the clamping tooth 131' is arranged on the elastic wall 132', so that the elastic wall 132' provides elastic force for the matching of the clamping tooth 223 and the tapered teeth 321.

[0058] In the third embodiment, the auxiliary positioning member 30 is a positioning column for cooperating with the second door body 310, the auxiliary positioning part 13 is a breakable connecting rib, and the positioning column is connected to the connecting rib. After the sliding connecting device 100 is installed, the second door body 310 is forced, the connecting rib is broken, and the positioning column is separated from the first sliding member 10, thus releasing the fixation between the first sliding member 10 and the second door body 310 and ensuring the normal sliding function between the first door body 210 and the second door body 310.

[0059] The first door body 210 has a thickness direction, and the first sliding member 10 also has a thickness direction. When the sliding connecting device 100 is assembled with the first door body 210 and the second door body 310, the first sliding member 10 is parallel between the first door body 210 and the second door body 310, the thickness direction of the first door body 210 is parallel to the thickness direction of the first sliding member 10, and is also parallel to the thickness direction of the second door body 310.

[0060] The fixing part 11 includes a mounting hole 113 for the first fastener to pass through and be fixed. The mounting hole 113 has a communicating pre-positioning opening and a fastening hole, and the pre-positioning opening is open in the thickness direction away from the first sliding part 12.

[0061] The fixing part 11 can be used for pre-positioning between the first sliding member 10 and the first door body, and can also be used for fixation between the first sliding member 10 and the first door body 210.

[0062] The fixing part 11 is fixed to the top surface of the first door body 210, and in other embodiments, it can also be fixed to the outer surface of the first door body 210. The first sliding part 12 is parallel to the outer surface of the first door body 210, and the fixing part 11 is perpendicular to the first sliding part 12.

[0063] The fixing part 11 includes a main body part 111 for arranging the mounting hole 113 and a cover body 112 connected to the main body part 111. The cover body 112 is rotatably connected to the main body part 111. After the fixing part 11 is fixed and installed on the first door body 210, the cover body 112 can be rotated to cover the main body part 111, thereby covering the mounting hole 113 arranged on the main body part 111 and covering the first fastener arranged on the mounting hole 113.

[0064] The first door body 210 has a length direction, and the first sliding member 10 also has a length direction. When the sliding connection device 100 is assembled with the first door body 210 and the second door body 310, the first sliding member 10 is parallel between the first door body 210 and the second door body 310, the length direction of the first door body 210 is parallel to the length direction of the first sliding member 10, and is also parallel to the length direction of the second door body 310. For the same component, for example, the first door body 210, the length direction is perpendicular to the thickness direction, and both the length direction and the thickness direction are horizontal directions, and both the length direction and the thickness direction are perpendicular to the height direction, and the height direction is a vertical direction.

[0065] The first door body 210 has a first length value, and the first sliding part 12 of the first sliding member 10 has a second length value, which is greater than one half of the first length value. In other words, compared with other hidden sliding connection assemblies, the first sliding member 10 of the present application provides a relatively long sliding distance, which can meet the requirement that there is still a large amount of remaining space after the first door body 210 is fully opened.

[0066] The first sliding member 10 has two fixing parts 11 and two auxiliary positioning parts 13, the two fixing parts 11 are symmetrically arranged in the length direction of the first sliding member 10, and the two auxiliary positioning parts 13 are symmetrically arranged in the length direction of the first sliding member 10. Because the first sliding member 10 is relatively long, the two symmetrically arranged fixing parts 11 and the two symmetrically arranged auxiliary positioning parts 13 are beneficial to the stability of the sliding cooperation between the first sliding part 12 and the second sliding member 20.

[0067] In an embodiment, the auxiliary positioning part 13 and the first sliding part 12 are located in the same vertical plane, and the fixing part 11 is perpendicular to the vertical plane; the fixing part 11 is located on the side of the vertical plane away from the auxiliary positioning part 13.

[0068] In an embodiment, the first sliding part 12 is arranged in a vertical sheet shape. The first sliding part 12 includes a sliding groove 120. The fixing part 11 is perpendicular to the first sliding part 12. The auxiliary positioning part 13 is arranged on the outer surface of the first sliding part 12.

[0069] The fixing part 11 and the auxiliary positioning part 13 are respectively arranged on both sides of the first sliding part 12 along the thickness direction. The fixing part 11 is arranged towards the first door body 210, and the auxiliary positioning part 13 is arranged towards the second door body 310, which is beneficial to the positioning cooperation between the first sliding part 12 and the first door body 210 and the second door body 310.

[0070] In an embodiment, the second sliding member 20 comprises a guide sleeve 21 and a second fastener 22 arranged on the guide sleeve 21. The second fastener 22 is used to fix the guide sleeve 21 to the second door body 310. The first sliding part 12 comprises a sliding groove 120, and the guide sleeve 21 passes through the sliding groove 120 and is in sliding cooperation with the sliding groove 120.

[0071] The center of the guide sleeve 21 is a hollow region, and the second fastener 22 passes through the hollow region of the guide sleeve 21 and is fixed to the second door body 310.

[0072] The first sliding member 10 further has a mounting mark 14 arranged on the first sliding part 12, which is used to indicate the mounting position of the second sliding member 20.

[0073] The guide sleeve 21 and the second fastener 22 are separately fixed parts, so the first sliding member 10 needs to be pre-designated with an initial mounting position to ensure that the second sliding member 20 is mounted in a proper position, and the sliding of the first sliding member 10 and the second sliding member 20 in an effective range position is realized.

[0074] In an embodiment, the second sliding member 20 comprises a second fastener 22, the first sliding part 12 comprises a sliding groove 120, the second fastener 22 passes through the sliding groove 120 and is in sliding cooperation with the sliding groove 120. The first sliding member 10 is provided with a mounting mark 14, which is used to indicate the mounting position of the second fastener 22.

[0075] In this embodiment, the guide sleeve 21 is cancelled, and the second fastener 22 is fixed to the second door body 210 and also used for sliding cooperation with the sliding groove 120. Similarly, the separately fixed part needs to be matched with the mounting mark 14 arranged to indicate the mounting position.

[0076] The first sliding part 12 is clamped between the first door body 210 and the second door body 310, and the second sliding member 20 comprises a guide sleeve 21 and a second fastener 22, which occupies a small space. The first sliding part 12 and the second sliding member 20 are hiddenly arranged between the first door body and the second door body, and have better aesthetics.

[0077] In combination with FIGS. 5-6, the mounting method of the door body assembly is described in detail below, which comprises the following steps:

[0078] Step S1: Open the first door body 210 and the second door body 310 respectively, so that the first door body 210 and the second door body 310 have a certain angle, fix the auxiliary positioning member 30 to the auxiliary positioning part 13, and then pre-position the first sliding member 10 to the first door body 210 through the fixing part 11.

[0079] Specifically, in combination with FIG. 5, in an embodiment, the second door body 310 is opened to about 90°, and the opening angle range is 80°-100°; in an embodiment, the first door body 210 is opened to about 45°, and the opening angle range is 30°-60°, which is not limited here, as long as there is space for operation and installation between the first door body 210 and the second door body 310.

[0080] In subsequent steps, the second door body 310 can remain stationary, and the first door body 210 can be operated to move closer to or away from the second door body 310. Therefore, during installation, in an embodiment, the second door body 310 remains open at 90 degrees; in actual operation, the opening angle of the second door body 310 is not limited.

[0081] When the auxiliary positioning member 30 is double-sided tape, the double-sided tape is pasted to the pasting groove of the auxiliary positioning member 30. When the auxiliary positioning member 30' is a hanging clamp, the positioning wall 32' is inserted into the insertion groove of the auxiliary positioning member 30'. When the auxiliary positioning member 30 is a positioning column, no further operation is required.

[0082] The first sliding member 10 includes two fixed parts 11 on both sides thereof, and the mounting holes 111 of the two fixed parts 11 are simultaneously in predetermined positioning cooperation with the first fasteners prepositioned on the first door body 210.

[0083] Step S2: The first door body 210 is operated to move closer to the second door body 310, so that the first door body 210 and the second door body 310 maintain the same angle, the auxiliary positioning member 30 is operated to be in positioning cooperation with the second door body 310, and the prepositioning of the first sliding member 10 and the first door body 210 is released.

[0084] Specifically, when the first door body 210 gradually moves closer to the second door body 310, if the auxiliary positioning member 30 is double-sided tape, it will gradually be pasted and fixed to the inner surface of the second door body 310; if the auxiliary positioning member 30 is a hanging clamp, the positioning wall 32' can be moved downward to make the alignment part 31' clamp and fix the top of the second door body 310; if the auxiliary positioning member 30 is a positioning column, the positioning column is inserted into the interior of the second door body 310 to achieve positioning cooperation.

[0085] In this application, since the prepositioning between the first door body 210 and the first sliding member 10 can be achieved by the fixed part 11 and the first fastener, as long as the first fastener is in a loosened state, the first sliding member 10 can be separated from the first door body 210.

[0086] Step S3: The first door body 210 is operated to move away from the second door body 310, and the second sliding member 20 is passed through the first sliding part 12 and fixed to the second door body 310.

[0087] As shown in FIG. 6, the first door body 210 is disengaged from the first sliding member 10, and the first sliding member 10 is further positioned on the second door body 310, so that the first sliding member 10 remains on the second door body 310 after the first door body 210 moves away from the second door body 310.

[0088] The step of installing the second sliding member 20 includes installing the guide sleeve 21 at the preset installation mark 14 of the first sliding member 10. It can be understood that the guide sleeve 21 passes through the sliding groove 120 from the side of the first sliding member 10 away from the second door body 310 and extends to the side of the second sliding member 10 facing the second door body 310.

[0089] The second fastener 22 is installed in the hollow area of the guide sleeve 21. Similarly, the guide sleeve 21 passes through the sliding groove 120 from the side of the first sliding member 10 away from the second door body 310 and is fixed to the inner surface of the second door body 310, so that the guide sleeve 21 is fixed to the second door body 310.

[0090] If the second sliding member 20 only includes the second fastener 22, the second fastener 22 is directly installed at the corresponding installation mark 14. Similarly, the second fastener 22 passes through the sliding groove 120 from the side of the first sliding member 10 away from the second door body 310 and is fixed to the inner surface of the second door body 310.
