[0024] The present invention will be described in detail below with reference to various embodiments shown in the accompanying drawings.

[0025] In the various drawings of the present invention, for the sake of convenience, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, only the basic structure of the subject matter of the present invention is illustrated.

[0026] See Figures 1 to 6 A refrigerator 100 provided by an embodiment of the present invention includes a shell 1, a hinge 2 and a hinge fixing device 3, and the hinge 2 is installed on the shell 1 of the refrigerator 100 through the hinge fixing device 3.

[0027] Among them, the hinge fixing device 3 includes a mounting groove 31 integrally provided with the shell 1, and a mounting seat 32 provided on the inner side of the shell 1. The mounting groove 31 is recessed from the outside to the inside on the shell 1. The hinge 2 is provided in the mounting groove 31 and is fastened to the mounting seat 32, so that the hinge 2 is embedded in the shell 1 of the refrigerator 100, avoiding the hinge 2 completely protruding from the shell 1 of the refrigerator 100, thereby preventing the package size from increasing due to the hinge 2 being completely protruded from the package 1, and the package from being damaged due to the hinge 2 being pierced during shipment, or even the hinge 2 being exposed outside the package, causing friction or damage.

[0028] See Figure 3 and Figure 5 Specifically, the mounting slot 31 includes an opening 311, a slot bottom wall 312 disposed vertically opposite the opening 311, and a pair of slot side walls 313 disposed laterally opposite each other. The mounting base 32 includes a bottom plate 321 and a pair of side plates 322 disposed laterally opposite each other. The bottom plate 321 abuts against the side of the slot bottom wall 312 facing away from the opening 311, and the pair of side plates 322 abut against the sides of the pair of slot side walls 313 facing away from each other. In this way, when installing the hinge 2, the bottom plate 321 not only serves to position the mounting base 32, thereby securing the hinge 2 to the mounting base 32, but also further restricts the lateral and upward movement of the mounting base 32 relative to the mounting slot 31.

[0029] See Figure 3 and Figure 5 Furthermore, the mounting base 32 also includes an inner plate 323 located inside the mounting groove 31 and extending up and down. The hinge 2 is fastened to the inner plate 323 to mount the hinge 2 on the housing 1.

[0030] See Figure 3 and Figure 5 When the lock 31 is unlocked, the lock 31 is unlocked, and the lock 31 is unlocked, so that the lock 31 is unlocked.

[0031] See Figures 2 to 5 Furthermore, a notch 3141 is formed on the edge of the inner wall 314 of the groove to connect the channel 315. Correspondingly, a mounting hole 324 that is adapted to the notch 3141 is also provided on the hinge 2 and the inner plate 323. The hinge 2 and the inner plate 323 are fastened together by a fastener arranged in the notch 3141. The fastener passes through the mounting hole 324 on the hinge 2, the notch 3141 on the mounting groove 31, and the mounting hole 324 on the inner plate 323 from the outside to the inside, thereby fastening the hinge 2, the mounting groove 31 and the mounting seat 32 together.

[0032] The fasteners may be screws, rivets or other fasteners, as long as they can pass through the mounting hole 324 and the notch 3141 and fasten the hinge 2 to the mounting slot 31 and the mounting seat 32 .

[0033] See Figure 3 、 Figure 5 as well as Figure 9 Furthermore, the groove bottom wall 312 and the groove side wall 313 are set to the same depth in the inner and outer directions, so that the inner plate 323 of the mounting seat 32 is tightly attached to the mounting groove 31, thereby improving the installation firmness of the hinge fixing device 3.

[0034] Furthermore, a bayonet 316 is formed between the groove bottom wall 312 and the groove side wall 313 , and between the groove bottom wall 312 and the groove inner wall 314 , and the boss 3231 is embedded in the bayonet 316 .

[0035] See Figures 2 to 3 Specifically, in this embodiment, the boss 3231 is in an inverted "T" shape, that is, the boss 3231 includes a vertical portion embedded in the channel 315 and a horizontal portion embedded in the bayonet 316. Through such a structural design, the boss 3231 of the mounting seat 32 is tightly matched with the mounting groove 31, limiting the movement of the mounting seat 32 relative to the mounting groove 31, and at the same time strengthening the strength of the shell 1 at the mounting groove 31, avoiding problems such as the hinge 2 being loosely installed and the shell 1 being damaged during installation or use.

[0036] See Figures 8 and 9 Furthermore, the outer edges of the bottom plate 321 and the pair of side plates 322 respectively abut against the inner surface of the shell 1, that is, the bottom plate 321 of the mounting base 32 covers the entire bottom wall 312 of the groove, and the pair of side plates 322 of the mounting base 32 facing the hinge 2 respectively abut against the inner surface of the shell 1 and respectively abut against the side of the groove side wall 313 facing away from each other, so as to reinforce the mounting groove 31 and further enhance the strength of the shell 1 at the mounting groove 31.

[0037] See 2 to Figure 5 Furthermore, the hinge fixing device 3 also includes a reinforcing iron 33, which is placed against the side of the hinge 2 seat facing away from the housing 1. A mounting hole 324 is also formed on the reinforcing iron 33 at the location corresponding to the notch 3141. The fastener passes through the mounting hole 324 on the hinge 2, the notch 3141 on the mounting groove 31, the mounting hole 324 on the inner plate 323, and the mounting hole 324 on the reinforcing iron 33 from the outside to the inside, thereby fastening the reinforcing iron 33 to the mounting seat 32, the mounting groove 31, and the hinge 2. To secure the hinge 2 to the housing 1, multiple mounting holes 324 can be provided, and correspondingly, multiple notches 3141 can also be provided.

[0038] See Figures 1 to 9 Furthermore, the outer shell 1 includes a cabinet shell 11 and a door shell 12. Each of the cabinet shell 11 and the door shell 12 is provided with a hinge fixture 3. The lower portion of the hinge 2 is coupled to the hinge fixture 3 in the cabinet shell 11 and engages in a mounting groove 31. The upper portion of the hinge 2 is coupled to the hinge fixture 3 in the door shell 12 and engages in a mounting groove 31. This allows the hinge 2 to be embedded in the outer shell 1, preventing it from completely protruding from the outer shell 1 of the refrigerator 100, thereby increasing the packaging size and causing the packaging to be easily damaged. Furthermore, the door shell 12 is connected to the cabinet shell 11 by the hinge 2, and the door shell 12 can rotate relative to the cabinet shell 11 to open or close the refrigerator 100.

[0039] Specifically, see Figures 2 to 3 In the hinge fixing device 3 of the cabinet housing 11, the bottom wall 312 of the groove is provided below the opening 311; see Figures 4 and 5 In the hinge fixing device 3 of the door shell 12 , the groove bottom wall 312 is provided above the opening 311 so that the hinge 2 is embedded in the shell 1 .

[0040] See Figures 1 to 2 Furthermore, the shell 1 also includes a mouth frame 13 provided on the upper part of the cabinet shell 11. The mouth frame 13 has a recess 131 recessed from the outside to the inside. The recess 131 is provided at the mounting groove 31 and has the same depth as the groove side wall 313, so that the hinge 2 can be embedded in the shell 1 of the refrigerator 100, thereby reducing the packaging size of the refrigerator 100 and avoiding problems such as the hinge 2 protruding from the shell 1 of the refrigerator 100 and causing damage to the packaging.

[0041] See Figure 1 In this embodiment, two hinges 2 are provided. Correspondingly, two hinge fixing devices 3 are also provided in the cabinet shell 11 and the door shell 12, so that the door shell 12 is subjected to uniform force during the opening or closing process.
