Next, the refrigerator 100 of the present embodiment will be specifically described by taking a first combination as an example.

Referring to fig. 1, a refrigerator 100 according to an embodiment of the present invention is shown.

The refrigerator 100 includes a cabinet 10, a door 20 to open and close the cabinet 10, and a hinge assembly 30 to connect the cabinet 10 and the door 20.

It should be emphasized that the structure of the present embodiment is applicable not only to the refrigerator 100 with the hinge assembly 30, but also to other scenes such as cabinets, sideboards, wardrobes, etc.

Referring to fig. 2 to 13, the hinge assembly 30 includes a first hinge member 31 fixed to the case 10, a second hinge member 32 fixed to the door 20, and a switching assembly 40 connecting the first hinge member 31 and the second hinge member 32.

When the door 20 is in the process of opening from the closed state to the first opening angle α1 (refer to fig. 18 to 21), the first shaft 311 rotates in place in the first free section S1 to drive the door 20 to rotate in place relative to the case 10.

When the door 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2 (refer to fig. 22 to 25), the fourth shaft 322 is separated from the limiting segment 4222, and the switching component 40 limits the first hinge member 31.

When the door 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3 (refer to fig. 26 to 29), the third shaft 321 rotates in place in the third free section 421, the fourth shaft 322 moves in place in the fourth free section 422 around the third shaft 321, and the door 20 continues to rotate in place relative to the case 10.

It should be noted that, in an example, referring to fig. 2 to 6, the door body 20 is provided with a first matching portion 25, the box body 10 is provided with a second matching portion 12, when the door body 20 is in a closed state, the first matching portion 25 and the second matching portion 12 are engaged with each other, and when the door body 20 is in a process of opening from the closed state to the first opening angle α1, the hinge assembly 30 drives the door body 20 to pivot relative to the box body 10 to drive the first matching portion 25 to separate from the second matching portion 12.

Here, the door body 20 rotates in place relative to the case body 10, that is, the door body 20 only rotates without generating displacement in other directions, so that the phenomenon that the first matching portion 25 cannot be separated from the second matching portion 12 due to displacement in a certain direction of the door body 20 can be effectively avoided.

Note that, the refrigerator 100 in the present embodiment may be a single-door refrigerator having the first engaging portion 25 and the second engaging portion 12, or a side-by-side refrigerator having the first engaging portion 25 and the second engaging portion 12, a multi-door refrigerator, or the like.

The first engaging portion 25 is a projection 25 protruding upward from the vertical beam 80.

The second matching portion 12 is fixedly arranged on the box 10, for example, the second matching portion 12 is a groove 12 on the base 104, the base 104 is fixedly arranged at the top of the accommodating chamber S, one end of the groove 12 is provided with a notch 121, the opening direction of the notch 121 faces forward, the protruding block 25 and the groove 12 are arc-shaped, and the protruding block 25 enters or leaves the groove 12 through the notch 121 so as to realize mutual limiting and mutual separation of the protruding block 25 and the groove 12.

Of course, it should be understood that the specific structure of the first engaging portion 25 and the second engaging portion 12 is not limited to the above description, that is, the first engaging portion 25 is not limited to the protruding block 25 at the vertical beam 80, the second engaging portion 12 is not limited to the groove 12 engaged with the protruding block 25, and the first engaging portion 25 and the second engaging portion 12 may be structures engaged with each other in other areas of the refrigerator 100.

Here, the sides of the first door 204 'and the second door 205' near the case 10 'may be provided with a door seal, and when the door 20' is in a closed state, the door seal contacts the contact surface 71 'of the fixing beam 70' to completely close the door 20', thereby preventing leakage of cool air in the case 10'.

When the door 20 'is in the process of opening from the closed state to the first opening angle α1, the door 20' rotates in place relative to the box 10', i.e. the door 20' only rotates and does not generate displacement in other directions, so that the door 20 'can be effectively prevented from being unable to be opened normally due to displacement in a certain direction of the door 20'.

At this time, if the first door 204 'is displaced in the horizontal direction when opened, the first door 204' and the second door 205 'will interfere with each other, so that the first door 204' and the second door 205 'cannot be opened normally, and the first door 204' and the second door 205 'are rotated in situ when opened in the refrigerator 100' according to the embodiment, so that the interference between the adjacent first door 204 'and second door 205' can be effectively avoided.

Here, the size of the through hole 4026 may be larger than the size of the third shaft 321, so that the third shaft 321 can move in the through hole 4026, and interference between the through hole 4026 and the third shaft 321 can be avoided when the first switching member 401 and the second switching member 402 move relatively.

That is, the third shaft 321 and the fourth shaft 322 of the present embodiment are located on different switching members, but not limited to this.

The first liner 4011, the first liner 4013, the second liner 4021, and the second liner 4023 are made of plastic, for example, polyoxymethylene (POM).

The first sliding piece 4012 and the second sliding piece 4022 are made of metal, for example, stainless steel or Q235 steel.

The outer contours of the first liner 4011, the first sliding vane 4012 and the first liner 4013 are matched with each other, the first liner 4011 and the first liner 4013 are matched with each other to clamp the first sliding vane 4012 therebetween, and slots are required to be formed in the first liner 4011, the first sliding vane 4012 and the first liner 4013 to form a first upper groove 413, a second upper groove 415 and a first through hole 4014.

Here, the first through hole 4014 may be formed by forming slots only in the first slider 4012 and the first bushing 4013, that is, the first through hole 4014 does not penetrate the first lining 4011, and at this time, the fifth shaft 50 extends from below the first switching element 401 into the first through hole 4011, and the first lining 4011 may shield the first through hole 4014 and the fifth shaft 50, thereby improving the aesthetic appearance.

The outer contours of the second liner 4021, the second sliding piece 4022 and the second bushing 4023 are matched with each other, the second liner 4021 is matched with the second bushing 4023 to clamp the second sliding piece 4022 between the two, and slots are required to be formed in the second liner 4021, the second sliding piece 4022 and the second bushing 4023 to form a first lower groove 414, a second lower groove 416 and a second through hole 4024 in a matched mode.

Here, the second through-hole 4024 may be formed by forming slots only in the second lining 4021 and the second slide 4022, that is, the second through-hole 4024 does not pass through the second bushing 4023, and at this time, the fifth shaft 50 extends from below the second bushing 4023 into the second through-hole 4024 and the first through-hole 4011, and the second bushing 4023 may cover the second through-hole 4024 and the fifth shaft 50, thereby improving the aesthetic appearance.

At this time, one end of the rivet stem 51 of the fifth shaft body 50 may be limited to the second bush 4023, and the mating effect of the second bush 4021, the second slide 4022, and the second bush 4023 may be further improved.

Here, the phrase "the first decorative sheet 4015 and the second decorative sheet 4025 are separated from each other" means that the first decorative sheet 4015 and the second decorative sheet 4025 are independent from each other, and when the first switching member 401 and the second switching member 402 are moved relatively, the first decorative sheet 4015 and the second decorative sheet 4025 are also moved relatively.

In addition, the first decorative sheet 4015 of the present embodiment is shaped like a "door", that is, the first decorative sheet 4015 only covers three sides of the first switching element 401, so that the first decorative sheet 4015 is convenient to be assembled, and the fastening structure can be provided at the three sides to realize the matching with the first decorative sheet 4015, and the width of the first decorative sheet 4015 is substantially equal to the sum of the thicknesses of the first liner 4011, the first sliding sheet 4012 and the first liner 4013 in the stacking direction of the first switching element 401 and the second switching element 402.

Similarly, the second decorative sheet 4025 is shaped like a gate, that is, the second decorative sheet 4025 only covers three sides of the second switching member 402, so that the second decorative sheet 4025 is convenient to assemble, and a fastening structure can be arranged at the three sides to realize the matching with the second decorative sheet 4025, and in the overlapping direction of the first switching member 401 and the second switching member 402, the width of the second decorative sheet 4025 is approximately equal to the sum of the thicknesses of the second lining 4021, the second sliding sheet 4022 and the second bushing 4023.

The first decorative sheet 4015 and the second decorative sheet 4025 may be made of ABS (Acrylonitrile Butdiene Styrene) plastic.

Next, a specific working procedure of the hinge assembly 30 will be described.

In the present embodiment, the case 10 includes an outer side 13 adjacent to the hinge assembly 30 and on an extension of a rotation path of the door 20, the door 20 includes a front wall 21 far from the accommodating chamber S and a side wall 22 always interposed between the front wall 21 and the accommodating chamber S, and a side edge 23 is provided between the front wall 21 and the side wall 22.

Referring to fig. 14 to 17, when the door 20 is in the closed state, the first switching member 401 and the second switching member 402 are relatively stationary, the first shaft 311 is located at the first free section S1, and the fourth shaft 322 is located at the limiting section 4222, so that the switching assembly 40 limits the second hinge member 32.

Specifically, the outer side 13 and the side wall 22 are located on the same plane, so that smoothness in appearance can be ensured, aesthetic appearance is improved, and the door 20 is convenient to install, but not limited to.

Here, when the door 20 is in the closed state, the third shaft 321 is located in the third free section 421, the fourth shaft 322 is limited in the limiting section 4222, the distance between the third shaft 321 and the fourth shaft 322 remains unchanged, the third shaft 321 is located in the first switching member 401, the fourth shaft 322 is located in the second switching member 402, and the first switching member 401 and the second switching member 402 are relatively stationary under the common limitation of the third shaft 321 and the fourth shaft 322.

Referring to fig. 18 to 21, when the door 20 is in the process of opening from the closed state to the first opening angle α1, the first switching member 401 and the second switching member 402 are relatively stationary, the overlapping portion of the first upper groove 413 and the first lower groove 414 forms a first free section S1, the first shaft 311 rotates in place in the first free section S1, and the recess 4016 abuts against the protrusion 314, so that the switching member 40 limits the first hinge member 31, and the door 20 rotates in place relative to the box 10.

Here, when the door 20 is in the closed state, the protrusion 314 is located in the recess 4016, the first limiting surface 3141 is far away from the second limiting surface 4017, when the door 20 is in the process of opening from the closed state to the first opening angle α1, the first hinge member 31 is fixed to the box 10, the door 20 drives the switching assembly 40 to move together with respect to the first hinge member 31, the protrusion 314 moves in the recess 4016, the first limiting surface 3141 and the second limiting surface 4017 gradually approach until the first limiting surface 3141 abuts against the second limiting surface 4017, at this time, the first switching assembly 401 cannot rotate with respect to the first hinge member 31 any more, that is, the switching assembly 40 realizes the locking of the first hinge member 31, and the size, shape, etc. of the protrusion 314 and the recess 4016 can be controlled to control the rotation angle of the door 20 when the first limiting surface 3141 abuts against the second limiting surface 4017.

In this embodiment, the door 20 rotates in place relative to the case 10 during the process of opening the door 20 to the first opening angle α1, so as to ensure that the door 20 cannot be displaced during this process.

It should be noted that, when the door 20 is in the process of opening from the closed state to the first opening angle α1, the fourth shaft 322 is always limited to the limiting segment 4222, so that the switching assembly 40 limits the second hinge member 32.

Referring to fig. 22 to 25, when the door 20 is in the process of being continuously opened from the first opening angle α1 to the second opening angle α2, the first switching member 401 and the second switching member 402 move relatively to disengage the fourth shaft 322 from the limiting segment 4222.

Specifically, when the first switching member 401 and the second switching member 402 move relatively, the distance between the third shaft 321 located on the first switching member 401 and the fourth shaft 322 located on the second switching member 402 changes, and the third shaft 321 is always located in the third free section 421, and the fourth shaft 322 moves from the limiting section 4222 to the fourth free section 4221, i.e. the fourth shaft 322 is separated from the limiting section 4222.

It should be noted that, the locking of the first hinge member 31 is not limited to the engagement of the protrusion 314 and the recess 4016, and in other embodiments, other structures may be used to lock the first hinge member 31, for example, locking the first shaft body 311 may be used to lock the first hinge member 31, specifically, a locking section may be provided at the first slot 411, and when the first shaft body 311 rotates to the locking section, locking of the first shaft body 311 may be achieved, or alternatively, a locking section may be formed between the first upper slot 413 and the first lower slot 414 due to relative movement of the first switching member 401 and the second switching member 402, and the locking section may be used to lock the first shaft body 311.

Referring to fig. 26 to 29, when the door 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, the first switching member 401 and the second switching member 402 are relatively stationary, the third shaft 321 rotates in place in the third free section 421, the fourth shaft 322 moves in place in the fourth free section 422 around the third shaft 321, and the door 20 continues to rotate in place relative to the case 10.

It can be seen that, in this embodiment, through the unlocking and locking actions of the switching component 40 on the first hinge member 31 and the second hinge member 32, the sequential switching of the first hinge member 31 and the second hinge member 32 can be effectively controlled, so that the door body 20 can be stably opened.

In the present embodiment, referring to fig. 30 and 31, the first switching member 401 includes a first stop portion 4018, the second switching member 402 includes a second stop portion 4027 that cooperates with the first stop portion 4018, and when the door body 20 is in the process of being closed from the second opening angle α2 to the first opening angle α1, the second switching member 402 restricts the movement of the first switching member 401 by cooperation of the second stop portion 4027 and the first stop portion 4018.

Specifically, the first stop portion 4018 is a groove body portion 4018 located on the first switching member 401, the second stop portion 4027 is a protrusion portion 4027 located on the second switching member 402, one end of the groove body portion 4018 is a stop end 4019, when the door body 20 is in the process of being opened from the closed state to the first opening angle α1, the first switching member 401 and the second switching member 402 are relatively static, the protrusion portion 4027 is kept at a side of the groove body portion 4018 away from the stop end 4019, when the door body 20 is in the process of being opened from the first opening angle α1 to the second opening angle α2, the first switching member 401 and the second switching member 402 are relatively moved, and the protrusion portion 402 is moved in the groove body portion 4018 toward a side close to the stop end 4019 until the protrusion portion 402 abuts the stop end 4019, and the first switching member 401 and the second switching member 402 are relatively static.

It can be understood that during the opening process of the door 20, the relative movement between the first switching member 401 and the second switching member 402 can be controlled by other structures, for example, the first switching member 401 and the second switching member 402 are abutted against the first shaft body 311 and the third shaft body 321 by the grooves on the first switching member 401 and the second switching member 402 to make the first switching member 401 and the second switching member 402 finish the relative movement, at this time, the first switching member 401 and the second switching member 402 remain relatively stationary and are in a mutually staggered state, preferably, when the first switching member 401 and the second switching member 402 finish the relative movement, the protrusion 402 just abuts against the stop end 4019, but not limited thereto.

The interaction between the protrusion 402 and the slot 4018 mainly acts during the closing of the door 20, in actual operation, when the door 20 is in the process of closing from the second opening angle α2 to the first opening angle α1, the first switching member 401 cannot rotate without rotating the second switching member 402 due to the abutment of the protrusion 402 against the stop end 4019, that is, in this process, it is inevitable that the rotation of the first switching member 401 is later than the rotation of the second switching member 402, and when the first switching member 401 and the second switching member 402 overlap, the first switching member 401 and the second switching member 402 are relatively stationary, and then the first switching member 401 moves together with the second switching member 402 relative to the first shaft 311 until the door 20 is closed.

It can be understood that the closing process of the door body 20 and the opening process of the door body 20 are the processes in reverse order, and the switching sequence of the first hinge member 31 and the second hinge member 32 in the opening and closing process of the door body 20 can be effectively controlled by the unlocking and locking actions of the switching assembly 40 on the first hinge member 31 and the second hinge member 32.

In the present embodiment, the first shaft body 311 and the third shaft body 321 are offset from each other, and thus, the present embodiment can be applied to a built-in cabinet or a scene where the space for accommodating the refrigerator 100 is small.

Referring to fig. 32, a simple schematic of the refrigerator 100 embedded in the cabinet 200 is illustrated.

In the present embodiment, the case 10 includes an opening 102 and a front end 103 disposed around the opening 102, the case 10 further includes a receiving chamber S and an outer side 13 adjacent to the hinge assembly 30 and on an extension of a rotation path of the door 20, the door 20 includes a front wall 21 far from the receiving chamber S and a side wall 22 always sandwiched between the front wall 21 and the receiving chamber S, and a side edge 23 is provided between the front wall 21 and the side wall 22.

Here, when the door body 20 is in the process of being opened to the first opening angle α1 in the closed state, the door body 20 rotates with the first shaft body 311 as an axis, a first distance is provided between the first shaft body 311 and the front end surface 103, and when the door body 20 is in the process of being continuously opened to the maximum opening angle α3 from the second opening angle α2, the door body 20 rotates with the third shaft body 321 as an axis, a second distance is provided between the third shaft body 321 and the front end surface 103, and the second distance is greater than the first distance, so that the maximum opening angle of the fully embedded refrigerator 100 can be greatly improved.

In addition, a third distance is provided between the first shaft body 311 and the outer side 13, and when the door body 20 is in the process of continuing to open from the second opening angle α2 to the maximum opening angle α3, a fourth distance is provided between the third shaft body 321 and the outer side 13, and the fourth distance is smaller than the third distance, so that the opening degree of the box 10 can be further increased.

The concrete explanation is as follows:

in some motion trajectories of the refrigerator 100, the first shaft 311 and the third shaft 321 move relative to the door 20, and for simplicity of illustration, the door 20 is simply considered to rotate around the first shaft 311, and then is switched to rotate around the third shaft 321 by the switching assembly 40.

In practice, in order to enhance the embedding effect, it is preferable that the refrigerator 100 is completely embedded in the cabinet 200, and the refrigerator 100 is a free embedded refrigerator, i.e., the front end 201 of the cabinet 200 is located on the same plane with the front wall 21 of the door 20 on the side far from the cabinet 10, or the front wall 21 of the door 20 does not protrude beyond the front end 201 of the cabinet 200 at all.

In the prior art, the refrigerator is a single-shaft refrigerator, and the rotation shaft of the refrigerator needs to keep a certain distance from the side wall and the front wall of the refrigerator, so that there is enough space to satisfy foaming or other processes, that is, the rotation shaft of the existing refrigerator is located at the position of the first shaft body 311 in fig. 32, in this case, after the single-shaft refrigerator is embedded into the cabinet 200, since the corner 203 of the cabinet 200 clamped between the front end 201 and the inner wall 202 is arranged corresponding to the side edge 23 of the door body 20, when the door body 20 is opened, the side edge 23 interferes with the door body 20 to limit the maximum opening angle of the door body 20, and in order to ensure the normal opening of the door body 20, the conventional practice is to increase the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100, which is about 10cm, which seriously affects the embedding effect and is unfavorable for the reasonable utilization of the limited space.

Referring to fig. 32, the hatched area indicates the door 20 in the closed state, when the door 20 is in the open process, if the door 20 is always rotated around the first shaft 311 (i.e. in the prior art), referring to the dashed line door 20 'in fig. 32, since the first shaft 311 is close to the front end surface 103, i.e. the first shaft 311 is far away from the front end 201 of the cabinet 200, after the door 20' is opened to a certain angle, the edge 203 of the cabinet 200 interferes with the door 20 'to limit the maximum opening angle of the door 20'.

In the present embodiment, the third shaft 321 is located on the first switching member 401, and during the opening process of the door 20, the switching assembly 40 moves relative to the first hinge member 31 and the second hinge member 32, so that the third shaft 321 gradually moves away from the front end surface 103, i.e. the third shaft 321 gradually moves towards the direction close to the front end 201 of the cabinet 200, i.e. at this time, the whole door 20 moves towards the direction away from the case 10, referring to the solid line door 20 in fig. 32, the interference effect of the edges 203 of the cabinet 200 on the door 20 is greatly reduced, and the edges 203 of the cabinet 200 interfere with each other when the door 20 is opened to a larger angle, thereby greatly improving the maximum opening angle of the door 20.

That is, the effect of the switching assembly 40 in this embodiment can make the later door 20 rotate around the third shaft 321, so that the maximum opening angle of the door 20 can be effectively increased on the premise of ensuring that the refrigerator 100 is freely embedded into the cabinet 200, thereby facilitating the user to operate the refrigerator 100 and greatly improving the user experience.

In addition, the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100 is not required to be increased, so that the refrigerator 100 and the cabinet 200 can be connected in a seamless manner, and the embedding effect is greatly improved.

In addition, the switching assembly 40 of the present embodiment drives the third shaft 321 to gradually move towards the direction close to the front end 201 of the cabinet 200, and simultaneously drives the third shaft 321 to gradually approach the inner wall 202 of the cabinet 200, that is, when the door 20 rotates around the third shaft 321, the third shaft 321 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first shaft 311, so that the maximum opening angle of the door 20 can be increased, and the door 20 can be further away from the box 10 to increase the opening of the box 10, thereby facilitating the opening and closing of the racks, drawers, and the like in the box 10, or facilitating the picking and placing of the articles.

Of course, the third shaft 321 serving as the rotation axis may be located at other positions, for example, when the door 20 rotates around the third shaft 321, the third shaft 321 is closer to the front end 201 of the cabinet 200 than the first shaft 311, and the third shaft 321 is farther from the inner wall 202 of the cabinet 200 than the first shaft 311.

It can be appreciated that the switching assembly 40 controls the switching sequence of the first hinge member 31 and the second hinge member 32 during the opening and closing process of the door 20, so as to effectively avoid the interference between the door 20 and the cabinet 200 during the opening and closing process.

In this embodiment, the hinge assemblies 30 located at different regions of the door 20 are different from each other, and the hinge assemblies 30 are hinge assemblies 30 located between the upper side of the door 20 and the case 10, and the hinge assemblies 30' located between the lower side of the door 20 and the case 10 will be briefly described with reference to fig. 33 and 34.

The lower hinge assembly 30' differs from the upper hinge assembly 30 in that: the first hinge member 31' of the lower hinge assembly 30' has a protrusion 313', the second hinge member 32' has a corresponding hook 323', the hook 323' is an elastic member, when the door 20 is in a closed state, the protrusion 313' acts on the hook 323' to deform so as to tightly fit the door 20 with the case 10, and when the door 20 is in an opening process, the door 20 drives the hook 323' to move, and the hook 323' deforms so as to separate from the protrusion 313'.

That is, when the door 20 is in the closed state, the protrusion 313 'is in interference fit with the hook 323', so as to enhance the closing effect of the door 20.

It should be noted that, since the switching element 40 'is connected between the first hinge element 31' and the second hinge element 32', the second hinge element 32' further includes an extension section 324 'of the switching element 40' along the thickness direction, and the extension section 324 'is connected with the hook 323', so that the hook 323 'is horizontally disposed and can be mutually matched with the protrusion 313'.

In the present embodiment, referring to fig. 35 to 38, the refrigerator 100 is the refrigerator 100 with the wiring module 60.

The routing module 60 includes a fixed end 61 and a free end 62 which are oppositely disposed, the fixed end 61 is connected with the door 20, the free end 62 is movably disposed on the box 10, and the routing E of the box 10 extends to the door 20 through the free end 62 and the fixed end 61 in sequence.

Here, the "free end 62 is movably disposed in the case 10" means that the free end 62 is not fixed to the case 10, and the free end 62 can move relative to the case 10 along with the opening of the door 20, so that the trace E in the trace module 60 can also move freely along with the opening of the door 20.

It should be noted that, along with the intellectualization and multifunctionalization of the refrigerator 100, some functional modules, such as an ice making module, a display module, and the like, are generally disposed on the door body 20 of the refrigerator 100, and these modules are generally required to be connected with the control module in the box 10 through the wiring E, and the wiring E in this embodiment extends to the door body 20 through the wiring module 60, so that a phenomenon that the wiring E is pulled during the opening and closing of the door body 20 can be effectively avoided, and the door body 20 with various movement tracks can be adapted, for example, when the hinge assembly 30 drives the door body 20 to move from the pivot side P toward the accommodating chamber S, the extending track of the wiring E can also be changed, and this movement of the door body 20 can be completely adapted through the design of the wiring module 60, that is, and the extending track of the wiring E can be flexibly adjusted through the wiring module 60, so as to avoid a wire blocking.

In this embodiment, the refrigerator 100 further includes a limiting space 101, the limiting space 101 includes a slot 1011 disposed towards the door body 20, the fixed end 61 of the wiring module 60 passes through the slot 1011 to be connected with the door body 20, when the door body 20 is in the opening process, the door body 20 drives the wiring module 60 to move in the limiting space 101, and the free end 62 is always located in the limiting space 101.

Here, the limiting space 101 is located at the top 11 of the box 10, the routing module 60 is disposed parallel to the top 11 of the box 10, and the fixed end 61 is movably connected to the door 20, however, the limiting space 101 may be disposed in other areas.

Specifically, in the present embodiment, the trace module 60 includes a first housing 601 and a second housing 602, the second housing 602 is disposed adjacent to the top 11 of the box 10, the first housing 601 is far away from the top 11 of the box 10 relative to the second housing 602, the first housing 601 and the second housing 602 cooperate with each other to form a housing cavity 603 for housing the trace E, and two ends of the housing cavity 603 are opened to form a fixed end 61 and a free end 62.

The door body 20 protrudes upwards from the top 11 of the box body 10, a stop 111 protruding from the top 11 is arranged at the edge of the top 11, which is close to the door body 20, a notch 1011 is arranged at the stop 111, the refrigerator 100 comprises a plurality of protruding parts 112 protruding from the top 11, and the plurality of protruding parts 112 are surrounded to form a limiting space 101.

Here, the first hinge member 31 is fixed at an edge position of the top 11, and in order to adapt to the design that the door body 20 protrudes out of the top 11, the first hinge member 31 of the hinge assembly 30 is generally Z-shaped, so that the first hinge member 31 may extend from the top 11 of the box body 10 to the top of the door body 20 to be mutually matched with the switching assembly 40 located at the top of the door body 20, and the plurality of protruding portions 112 include a first protruding portion 1121 located between the first hinge member 31 and the routing module 60 and a second protruding portion 1122 spaced from the first protruding portion 1121, the first protruding portion 1121 may avoid the routing module 60 interfering with the first hinge member 31, and the profile of the first protruding portion 1121 may be matched with the movement track of the routing module 60, and the second protruding portion 1122 may be a plurality of protruding columns to reduce the impact between the routing module 60 and the second protruding portion 1122.
