[0036] Embodiment 1

[0037] As shown in Figure 1 , Figure 3 , Figure 4 , the present invention provides a pre-buried installation structure for a storage box, including a fixed base 100; the fixed base 100 is pre-buried on the side of the door liner 300 of the household appliance door body 10 facing away from the household appliance box body to form a sealing structure on one side of the household appliance door body; the fixed base 100 is provided with a connection part 1111 for rotatably connecting with the storage box 200; the connection part 1111 matches the position of the second through groove 311 provided on the side wall of the concave part 310 of the door liner 300; wherein,

[0038] The connecting portion or the storage box passes through the second through groove 311. The connecting portion 1111 is rotatably connected to the outer wall of the storage box 200, that is, through the second through groove 311, the connecting portion 1111 and the storage box 200 are rotatably connected to realize the installation of the storage box 200, so that the storage box 200 can rotate relative to the door liner 300 within the door liner 300, and the storage box 200 rotates relative to the door liner 300.

[0039] In an embodiment, after the fixing base 100 is embedded in the side of the door liner 300 of the household appliance door body 10 facing away from the household appliance box body, the fixing base 100 covers the back surface of the side wall of the second through groove 311 provided in the recessed portion 310 to cover the second through groove 311, forming a sealing structure on one side of the household appliance door body to prevent the foaming material from overflowing from the second through groove 311 of the door liner 300 during subsequent foaming.

[0040] In an embodiment, the two connecting portions 1111 are respectively located on both sides of the back surface of the recessed portion 310 of the door liner 300. A second through groove 311 is provided on each of the two side walls of the recessed portion 310, corresponding to the positions of the two connecting portions 1111 respectively, to make way for the rotatable connection of the connecting portion 1111 and the connecting shaft 220 of the storage box 200.

[0041] In an embodiment, the two connecting portions 1111 are both located on one side of the back surface of the recessed portion 310 of the door liner 300; the connecting shaft 220 of the storage box 200 is arranged at the bottom end of the box body 210 of the storage box 200, facing away from the opening end of the storage box 200. At this time, the distance from the opening end of the storage box 200 to the rotation connection point between the storage box 200 and the fixing base 100 is the farthest, and the distance between the opening end of the storage box 200 and the door liner 300 can be maximized. A second through groove 311 is provided on the corresponding side wall of the recessed portion 310 to make way for the rotation connection of the two connecting portions 1111 and the two connecting shafts 220 of the storage box 200. Or, two second through grooves 311 are provided on the corresponding side wall of the recessed portion 310, corresponding to the positions of the two connecting portions 1111 respectively. When the connecting shaft 220 is located at the bottom end of the box body 210 of the storage box 200, when the storage box 200 is opened, that is, the opening end of the box body 210 rotates relative to the connecting shaft formed by the two connecting shafts 220 at its bottom end, and the opening end of the box body 210 gradually moves away from the door liner 300. Further, due to the limitation of the inner wall of the recessed portion 310 of the door liner 300, the opening end of the box body 210 can only rotate a certain angle relative to the corresponding connecting shaft, that is, finally the storage box 200 is opened at a certain angle. According to requirements, the distance between the end of the connecting shaft 220 of the storage box 200 and the bottom end of the box body 210, and the specific position of the storage box 200 in the recessed portion 310 of the door liner 300 can be adjusted to adjust the opening angle of the storage box 200. In an embodiment, such as Figure 1 、 Figure 3As shown in the figure, a groove 111 is provided on one side of the fixed seat 100 facing the second through groove 311, and the connecting portion 1111 is arranged in the groove 111. The connecting shaft 220 of the storage box 200 extends into the groove 111 after passing through the second through groove 311 of the door liner 300 and is rotatably connected to the connecting portion 1111.

[0042] Further, the groove 111 is arranged on the first side wall 110 of the fixed seat 100; the first side wall 110 abuts against the back surface of the side wall of the recessed portion 310 to close the second through groove 311. That is, both connecting portions 1111 are located on the same side of the back surface of the recessed portion 310 of the door liner 300. The first side wall 110 of the fixed seat 100 provided with the groove 111 can abut against the back surface of the side wall of the recessed portion 310 of the door liner 300 provided with the second through groove 311, and the groove 111 corresponds to the second through groove 311. While facilitating the rotational connection between the storage box 200 and the fixed seat 100, the contact between the second through groove 311 of the door liner 300 and the foaming layer is separated by the first side wall 110 of the fixed seat 100, realizing the closure of the second through groove 311.

[0043] In one embodiment, the number of grooves 111 is at least two. Further, the number of grooves 111 is two, and the two connecting portions 1111 are respectively arranged in the two grooves 111. Further, the first side wall 110 provided with the groove 111 is provided with a second notch 112 to separate the two grooves 111, so as to facilitate the abutment of the side walls respectively provided with the grooves 111 against the back surface of the side wall of the recessed portion 310 provided with the second through groove 311, reducing the requirement for the processing accuracy of the first side wall 110 during the production of the fixed seat 100.

[0044] Further, the outer contour of the second through groove 311 of the door liner 300 covers the outer contour of the groove 111, and the groove 111 is completely exposed through the second through groove 311, facilitating the subsequent installation of the storage box 200.

[0045] In one embodiment, as Figure 3As shown, a part of the side wall of the fixing base 100 facing the door liner 300 is magnetically adsorbed to the storage box 200, so that the storage box 200 is fixed on the door liner 300. Specifically, the fixing base 100 is provided with a magnet 130; the position of the magnet 130 corresponds to that of the iron part 230 provided on the storage box 200. Further, the iron part 230 is arranged on the outer wall of the side of the storage box 200 away from the household electrical appliance box body. When the storage box 200 is opened, the box body 210 of the storage box 200 rotates relative to the rotation connection part of the storage box 200 and the fixing base 100. After moving away from the outer surface of the door liner 300 and taking and placing items, when an external force causes the storage box 200 to approach the door liner 300, the magnetic attraction force between the magnet 130 and the iron part 230 promotes the storage box 200 to approach the door liner 300, playing a role in assisting the storage box 200 to reset. In addition, the magnetic attraction between the magnet 130 and the iron part 230 makes the storage box 200 firmly close to the inner wall of the recessed part 310 of the door liner 300. Only by cooperating with the rotational connection between the storage box 200 and the fixing base 100 can the requirement of installing the storage box 200 in the recessed part 310 be met.

[0046] In one embodiment, as Figure 1 、 Figure 3 shown, the fixing base 100 has a bent structure and further includes a second side wall 120; the second side wall 120 is provided with a fixing structure 121 for installing the magnet 130.

[0047] The first side wall 110 is connected to the second side wall 120 and respectively abuts against two outer walls on the back of the recessed part 310 of the door liner 300. The connection part between the first side wall 110 and the second side wall 120 forms a bent part of the fixing base 100, which can improve the closing effect of the fixing base 100 on the second through groove 311 of the door liner 300 to a certain extent.

[0048] In one embodiment, as Figure 1 、 Figure 2 shown, the fixing structure 121 includes at least two snap structures 1211 that form a relative snap force to snap the magnet 130 for loading and unloading the magnet 130, and the magnet 130 is easy to load and unload. Further, the number of the snap structures 1211 is two, which are opposite in position and respectively snap the two sides of the magnet 130.

[0049] Further, the fixing structure 121 further includes a first through groove 1212 for accommodating the magnet 130; at least two snap structures 1211 that form a relative snap force are respectively disposed on two side walls of the first through groove 1212. The two snap structures 1211 that form a relative snap force press the magnet 130 accommodated in the first through groove 1212 against the back surface of the recessed portion 310 of the door liner 300, and the magnet 130 is directly attached to the side of the door liner 300 facing away from the storage box 200, reducing the obstacles between the magnet 130 and the iron member 230 fixed on the storage box 200, and improving the adsorption force between the magnet 130 and the iron member 230.

[0050] In one embodiment, the inner contour of the first through groove 1212 wraps the outer contour of the magnet 130, and the shape and size of the inner contour of the first through groove 1212 match the shape and size of the outer contour of the magnet 130 to limit the movement of the magnet 130 in the circumferential direction and improve the installation firmness of the magnet 130.

[0051] In one embodiment, first notches 1213 are respectively provided on two sides of the snap structure 1211. Further, the snap structure 1211 includes a buckling portion 12111 and a receiving portion 12112. The buckling portions 12111 of the two snap structures 1211 respectively buckle the outer wall of the magnet 130 away from the door liner 300, and the receiving portions 12112 of the two snap structures 1211 respectively abut against the opposite outer walls of the magnet 130 to achieve snap fixation of the magnet 130. The two first notches 1213 are respectively disposed on two sides of the receiving portion 12112, reducing the deformation difficulty of the snap structure 1211 when the snap structure 1211 is used for loading and unloading the magnet 130. The first notches 1213 on two sides of the two snap structures 1211 may be the same or different. In one embodiment, the length of the first notches 1213 on two sides of one snap structure 1211 is less than the length of the first notches 1213 on two sides of the other snap structure 1211, so that when loading and unloading the magnet 130, the deformations of the two snap structures 1211 are different, facilitating the loading and unloading of the magnet 130 while ensuring the snap force of the two snap structures 1211 on the magnet 130.

[0052] In one embodiment, as Figure 5 shown, the connecting portion 1111 is a shaft hole. The side of the connecting portion 1111 facing the second through groove 311 is an opening; two clamping protrusions 11111 for clamping the connecting shaft 220 of the storage box 200 are provided at the opening of the connecting portion 1111. The connecting shaft 220 of the storage box 200 is inserted into the connecting portion 1111 from the opening of the connecting portion 1111, and the clamping protrusions 11111 in the connecting portion 1111 clamp the connecting shaft 220, so that the connecting shaft 220 of the storage box 200 will not be disengaged from the connecting portion 1111 without external force disassembly; realizing the detachable connection between the storage box 200 and the fixing base 100, facilitating the maintenance or replacement of the storage box 200.

[0053] In one embodiment, the fixing base 100 abuts against each outer surface at one end of the back surface of the recessed portion 310. Generally, the outer contour of the door liner 300 of the household appliance door 10 is rectangular, and one end of the back surface of the recessed portion 310 of the door liner 300 includes four outer walls, and the fixing base 100 includes four side walls to respectively abut against the four outer walls of the back surface of the recessed portion 310, so that the fixing base 100 forms a certain pressing force to snap the back surface of the recessed portion 310 into the fixing base 100, improving the installation firmness between the fixing base 100 and the door liner 300.
