The fold 112 is used to fix and position the mounting box 2, and can also partially or completely close the mounting gap between the front panel 11 and the mounting box 2. In some embodiments, the fold 112 is in the form of a ring-shaped closed structure surrounding the pouring interface 111, thereby fixing and positioning the mounting box 2 in all directions, and completely closing the mounting gap between the front panel 11 and the mounting box 2.

[0048] Referring to Figure 7 and Figure 8 , in some embodiments, the rear end of the fold 112 is provided with an extension 113 extending rearward. The extension 113 can be formed by extending the rear end of the fold 112. The extension 113 is used to align and insert fit with the mounting box 2, and can further fix and position the mounting box 2, and strengthen the fixing strength between the mounting box 2 and the front panel 11.

[0049] Referring to Figure 8 , in some embodiments, the rear end of the extension 113 is provided with a bayonet 114. The bayonet 114 can be square, round or any other shape. When the extension 113 aligns and inserts fit with the mounting box 2, the bayonet 114 of the extension 113 can be buckled with the mounting box 2, thereby fixing the extension 113 and the fold 112 on the mounting box 2, and fixing the mounting box 2 on the front panel 11.

[0050] Referring to Figure 2 and Figure 3 , the mounting box 2 is installed at the pouring interface 111 and located at the rear side of the front panel 11. The mounting box 2 has a receiving cavity 201 formed therein, which can be used as a water taking cavity or an ice taking cavity. The receiving cavity 201 is an open cavity, and the front side of the receiving cavity 201 is open and connected to the pouring interface 111. Therefore, the user can reach into the mounting box 2 through the pouring interface 111. The top of the mounting box 2 can be provided with a water drinking device or an ice making device above the receiving cavity 201, and the water outlet of the water drinking device or the ice outlet of the ice making device is located at the top of the receiving cavity 201, so that the user can take cold water or ice in the receiving cavity 201.

[0051] Referring to Figure 5 , the mounting box 2 includes a box body 21 having an opening on the front side and a flange 22 bent from the opening of the box body 21 to the peripheral side.

[0052] The box body 21 is provided with the accommodating cavity 201. The front side of the box body 21 is open as the front side of the accommodating cavity 201 and is opposite to the receiving interface 111. The front end of the box body 21 can be embedded in the door cavity, and the rear end of the box body 21 can be protruded out of the door cavity and distributed in the corresponding refrigeration compartment of the cabinet.

[0053] The front surface of the flange 22 is attached to the rear surface of the front panel 11. The flange 22 has a ring structure and surrounds the receiving interface 111. That is, the flange 22 is attached to the edge of the receiving interface 111, and the shape of the flange 22 is the same as the contour shape of the receiving interface 111.

[0054] Please refer to Figure 5 In some embodiments, a sealing gasket 16 is arranged between the front surface of the flange 22 and the rear surface of the front panel 11. The sealing gasket 16 can be sealingly sleeved on the circumferential side of the flange 112, so as to seal the gap between the flange 22 and the front panel 11, thereby effectively preventing the foaming material in the door cavity from leaking out of the door body 1 when the door cavity is filled with the foaming material.

[0056] Figure 9 is Figure 5 is a structural schematic view of the installation box 2. Figure 10 is Figure 9 is an enlarged structural schematic view of the D area in FIG. 8.

[0057] Please refer to Figure 5 and Figure 9 The flange 22 is concavely provided with a slot 23 opposite to the flange 112. The slot 23 is located on the front surface of the flange 22 and is concavely formed from the flange 22 to the rear side of the front panel 11. The flange 112 can be inserted into the slot 23 and make the flange 22 attached to the rear surface of the front panel 11, thereby positioning and installing the installation box 2 at the receiving interface 111 of the front panel 11. That is, by using the slot 23 on the installation box 2 and the flange 112 on the front panel 11, the installation box 2 and the front panel 11 can be quickly and accurately connected, thereby positioning and installing the installation box 2 and enhancing the fixing strength of the installation box 2.

[0058] The slot 23 is an annular groove and is distributed around the opening of the box 21. The annular slot 23 can cooperate with the folded edge 112 of the annular structure to position, install and fix the periphery of the mounting box 2.

[0059] Please see Figure 6 and Figure 10 In some embodiments, the bottom of the slot 23 has an insertion hole 24 that extends along the front and rear of the flange 22. The extension 113 can be aligned and inserted into the insertion hole 24, and is distributed on the outer side of the box wall of the box body 21 through the insertion hole 24. That is, by utilizing the alignment and cooperation between the insertion hole 24 and the extension 113, a quick connection between the mounting box 2 and the front panel 11 can be pre-achieved. After the extension 113 is inserted into the insertion hole 24, the flange 112 can be inserted into the slot 23, improving installation efficiency. At the same time, the cooperation between the insertion hole 24 and the extension 113 can also further enhance the fixing strength of the mounting box 2.

[0060] Please see Figure 7 and Figure 9 In some embodiments, multiple insertion holes 24 are provided within the slot 23, and these holes 24 are arranged at intervals around the opening of the housing 21 along the circumference of the slot 23. Simultaneously, multiple extensions 113 are also provided on the front panel 11, and the extensions 113 are arranged in a one-to-one correspondence with the insertion holes 24. That is, by utilizing the cooperation of multiple extensions 113 and insertion holes 24, the periphery of the mounting box 2 is circumferentially fixedly connected to the front panel 11, effectively ensuring the stability of the connection.

[0061] Figure 11 yes Figure 9 The front view. Figure 12 yes Figure 11 EE sectional view. Figure 13 yes Figure 12 A magnified structural diagram of region F in the middle.

[0062] Please see Figures 9 to 13 In some embodiments, a guide portion 25 is also provided within the slot 23. The width of the slot 23 is greater than the width of the insertion hole 24. The guide portion 25 is located on one side of the insertion hole 24 and can extend from one inner wall of the slot 23 to the other inner wall, so that the insertion hole 24 is located between the guide portion 25 and the other inner wall of the slot 23. At the same time, a guide wall 251 is formed on the side of the guide portion 25 facing the insertion hole 24. The guide wall 251 is inclined in the direction of gradually increasing the width of the slot 23 in the direction towards the outside of the slot 23, thereby forming an entrance structure that is wider on the outside and narrower on the inside at the entrance of the slot 23 corresponding to the insertion hole 24. The extension portion 113 can be smoothly inserted into the insertion hole 24 through this entrance structure, along the guide wall 251 of the guide portion 25. That is, with the guiding function of the guide portion 25, the extension portion 113 can be quickly aligned and installed, further improving installation efficiency and simplifying the operation difficulty of installation.

[0063] In some embodiments, the slot 23 is further provided with a clamping block 26. The clamping block 26 is formed on the inner side wall of the same side of the slot 23 as the guide portion 25. The clamping block 26 can also be formed by the inner side wall of one side of the slot 23 extending to the inner side wall of the other side. When the folded edge 112 is inserted into the slot 23, the folded edge 112 is clamped between the clamping block 26 and the inner side wall of the other side of the slot 23. That is, when the extension portion 113 is inserted into the jack 24 by the guide wall 251 of the guide portion 25, the folded edge 112 can be inserted into the slot 23 and clamped between the clamping block 26 and the inner side wall of the other side of the slot 23. In addition, the clamping block 26 is provided with a plurality of clamping blocks arranged circumferentially and spaced apart along the inner side wall of the slot 23 on the opening side of the box body 21.

[0064] Please refer to Figure 3 , Figure 6 and Figure 13 In some embodiments, the outer wall of the box body 21 is provided with a clamping protrusion 211 spaced apart from the rear side of the jack 24. When the extension portion 113 is inserted into the jack 24, the rear end of the extension portion 113 passes through the jack 24 and is connected by the bayonet 114 and the clamping protrusion 211. By cooperating the bayonet 114 of the extension portion 113 with the clamping protrusion 211 of the box body 21, the extension portion 113 can be buckled on the box body 21, thereby achieving the buckling and fixing of the box body 21 and the front panel 11. That is, in the installation process of the mounting box 2 of the present embodiment, only the jack 24 of the mounting box 2 and the extension portion 113 of the front panel 11 need to be aligned, and the extension portion 113 can be automatically buckled on the clamping protrusion 211 of the mounting box 2 when the extension portion 113 is inserted into the jack 24, thereby completing the quick installation and fixing of the mounting box 2 without the need for other tools or tapes for locking and fixing.

[0065] In some embodiments, the clamping protrusion 211 is formed with a guide inclined surface 2111 at one end away from the outer wall of the box body 21. The guide inclined surface 2111 is inclined away from the box body 21 in the direction away from the jack 24. That is, when the extension portion 113 is inserted into the jack 24 and contacts the clamping protrusion 211, the rear end of the extension portion 113 abuts against the guide inclined surface 2111, and when the extension portion 113 continues to be inserted into the jack 24, the guide inclined surface 2111 can cause the extension portion 113 to be bent and deformed to a certain extent towards the outer end of the clamping protrusion 211, so that the bayonet 114 is opposite to the outer end of the clamping protrusion 211, and then buckled on the clamping protrusion 211.

[0066] Still please refer to Figure 3 , Figure 6 and Figure 13In some embodiments, a sleeve 27 is arranged on the outer wall of the box 21 between the insertion hole 24 and the clamping protrusion 211. The sleeve 27 extends rearward from the edge of the rear end outlet of the insertion hole 24, and a certain space is present between the sleeve 27 and the clamping protrusion 211. When the extension part 113 is inserted into the insertion hole 24, the extension part 113 passes through the insertion hole 24 and the sleeve 27 in sequence, and then is buckled with the clamping protrusion 211. That is, the sleeve 27 can further guide the extension part 113 that passes out of the insertion hole 24, so that the extension part 113 is smoothly buckled on the clamping protrusion 211; meanwhile, the buckling strength of the extension part 113 and the clamping protrusion 211 is enhanced, so that the extension part 113 and the clamping protrusion 211 are prevented from being separated.

[0067] Based on the above technical solution, the embodiments of the present application have at least the following advantages and positive effects:

[0068] In the refrigerator of the embodiments of the present application, the folding edge 112 at the edge of the receiving interface 111 on the door body 1 is inserted into the insertion slot 23 on the opening side of the mounting box 2, and when the mounting box 2 is installed, the insertion slot 23 of the mounting box 2 is aligned with the folding edge 112 on the door body 1, the folding edge 112 is inserted into the insertion slot 23, and then the folded edge 22 of the mounting box 2 is attached to the inner side wall of the door body 1, so that the installation operation of the mounting box 2 can be effectively simplified, the installation efficiency of the mounting box 2 is improved, and the installation stability of the mounting box 2 is increased by the cooperation of the folding edge 112 and the insertion slot 23.
