In this way, the door body 20 cannot be smoothly separated from the box body 10 due to the obstruction of the door seal 26 (for example, excessive squeezing of the door seal 26, excessive magnetic attraction force, etc.), and It is convenient for the user to open the door body 20.

It should be noted that the refrigerator 100 of this embodiment is not only suitable for avoiding the obstruction of the door seal 26, but may also have other structures obstructing the opening of the door body 20, such as frost formation between the box body 10 and the door body 20.

In this embodiment, when the door body 20 is in the process of opening, the hinge assembly 30 drives the door body 20 to move away from the box body 10 in the first direction X, and at the same time, the hinge assembly 30 drives the door body 20 to move from the pivoting side P toward the housing The chamber S moves.

Here, when the door body 20 is in the process of opening, the door body 20 moves toward the side of the accommodating chamber S, that is, at this time, the door body 20 both rotates relative to the box body 10 and produces a second direction Y relative to the box body 10. In this way, the distance that the door body 20 protrudes from the box body 10 toward the side away from the containing chamber S during the rotation process will be greatly reduced, that is, the displacement of the door body 20 in the second direction Y offsets the door body 20 The portion protruding out of the box body 10 during the rotation process prevents the door body 20 from interfering with the surrounding cabinets or walls during the opening process, and is suitable for scenes with built-in cabinets or small spaces for accommodating the refrigerator 100.

It should be noted that during the opening process of the door body 20 of this embodiment, the door body 20 moves toward the first direction X and the second direction Y at the same time, so that the door body 20 can be opened smoothly. At the same time, the door body 20 will not interact with each other. The surrounding cabinets or walls interfere.

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

Next, the specific working process of the hinge assembly 30 is introduced.

In this embodiment, the box body 10 includes an outer side surface 13 adjacent to the hinge assembly 30 and on the extension section of the rotation path of the door body 20. The door body 20 includes a front wall 21 away from the containing chamber S and is always sandwiched on the front wall 21 The side wall 22 between the accommodating chamber S and the front wall 21 has a side edge 23 between the front wall 21 and the side wall 22.

7 to 10, when the door 20 is in the closed state, the first switching member 401 and the second switching member 402 are relatively stationary, and the first upper free section 4131 and the first lower free section 4141 overlap to form a first free section S1 , The second upper free section 4151 and the second lower free section 4161 overlap to form a second free section S2, the first shaft body 311 is located at the initial position A1, and the second shaft body 312 is located at one end of the second free section S2.

Specifically, the outer side surface 13 and the side wall 22 are located on the same plane, which can ensure the smoothness of the appearance, improve the aesthetics, and also facilitate the installation of the door body 20, but it is not limited to this.

11 to 14, when the door body 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, and the first upper free section 4131 and the first The lower free section 4141 overlaps to form a first free section S1. The second upper free section 4151 and the second lower free section 4161 overlap to form a second free section S2. The second shaft 312 moves in the second free section S2 to drive the first free section S2. The shaft body 311 moves from the initial position A1 to the stop position A2, the door body 20 moves away from the box body 10 in the first direction X, the distance between the side door seal 261 and the front end surface 103 increases, and at the same time, the door body 20 moves from the pivoting side P moves toward the accommodating chamber S.

In the prior art, because it is a single-axis hinge assembly, the door body always rotates in situ relative to the box body. In actual operation, it is necessary to consider the thickness of the door seal, the thickness of the door body and other factors to design the axis position in the hinge assembly. The door seal will not hinder the opening process of the door body. However, the design process of the axis position is more complicated, and due to the influence of factors such as installation accuracy, the axis position cannot be maintained at the pre-designed position.

In this specific example, the door body 20 moves away from the front end of the box body 10 through the cooperation of the double shaft and double groove, which can effectively solve the problem of the door seal 26 obstructing the opening process of the door body 20, and does not require high installation accuracy, which can greatly Reduce design cost and installation difficulty.

In addition, it should be noted that when the door 20 is opened, the hinge assembly 30 drives the door 20 to move away from the front end of the box 10, which can effectively assist the opening of the door 20. At the same time, the hinge assembly 30 drives the door 20 by The pivoting side P moves toward the accommodating chamber S to prevent the door body 20 from protruding out of the box body 10.

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

In addition, in this process, since the first upper free section 4131 and the first lower free section 4141 always overlap into the first free section S1, the second upper free section 4151 and the second lower free section 4161 always overlap into the second free section. S2, that is, the trajectories of the first switching element 401 and the second switching element 402 are exactly the same, and the first shaft 311 moves in the first free section S1, and at the same time, the second shaft 312 moves in the second free section S2. During this process, the first switching element 401 and the second switching element 402 will never be staggered with each other, that is, the first switching element 401 and the second switching element 402 remain relatively stationary, which can avoid the first upper free section 4131 and the first lower free section 4141 are mutually misaligned, and at the same time, the second upper free section 4151 and the second lower free section 4161 are prevented from displacing each other. In this way, the smooth movement of the first shaft body 311 in the first free section S1 can be ensured, and the second shaft body 312 is free in the second free section. Section S2 moves smoothly.

15 to 18, when the door body 20 is in the process of continuing to open from the first opening angle α1 to the second opening angle α2, the first switching member 401 and the second switching member 402 move relative to each other to make the fourth shaft body 322 is separated from the limiting section 4222, and the first shaft body 311 and/or the second shaft body 312 are limited in the

locking section

4132, 4142, 4152, 4162, so that the switching assembly 40 limits the first hinge member 31.

Here, "the first switching member 401 and the second switching member 402 move relative to each other so that the second hinge member 32 is disengaged from the limit of the switching assembly 40, and the first shaft body 311 and/or the second shaft body 312 are limited to the

locking section

4132, 4142, 4152, 4162 and the switch assembly 40 to limit the first hinge member 31" refers to the relative movement between the switch assembly 40 and the second hinge member 32 so that there is no between the switch assembly 40 and the second hinge member 32 Restricting each other, the relative movement between the switching assembly 40 and the first hinge part 31 causes the switching assembly 40 and the first hinge part 31 to be restricted to each other.

In this embodiment, the first shaft body 311 is confined to the first upper locking section 4132 and the first lower locking section 4142 at the same time, and the second shaft body 312 is confined to the second upper locking section 4152 and the second lower locking section at the same time. The stop section 4162, and the fourth shaft body 322 departs from the fourth limit section 4222, the description is as follows:

When the door body 20 is opened to the first opening angle α1, the second shaft 312 moves from the second free section S2 to the second lower locking section 4162 and is limited. At this time, the first shaft 311 and the second shaft 312 Can no longer move relative to the first free section S1 and the second free section S2, and at this time, the first shaft body 311 is adjacent to the first upper locking section 4132 and the first lower locking section 4142, and the second shaft body 312 is adjacent to the second The trajectories of the upper locking section 4152, the first upper locking section 4132 and the second upper locking section 4152 are adapted to the movement paths of the first shaft body 311 and the second shaft body 312.

When the door body 20 continues to open on the basis of the first opening angle α1, the door body 20 drives the second hinge member 32 connected to the door body 20 to move, and the second hinge member 32 passes through the third free section 4211 and the fourth limit section At 4222, a force is applied to the third shaft 321 and the fourth shaft 322, and then the third shaft 321 and the fourth shaft 322 drive the first switching element 401 and the second switching element 402 to move.

Specifically, at this time, the first shaft body 311 is adjacent to the first upper locking section 4132, the second shaft body 312 is adjacent to the second upper locking section 4152, and the first switching member 401 can be opposed to the first shaft body 311 and the second shaft body. 312 moves by a first angle until the first shaft body 311 is confined to the first upper locking section 4132, and the second shaft body 312 is confined to the second upper locking section 4152, and at the same time, the second switching member 402 is positioned at the fifth shaft body 50 is the center of the circle and moves a second angle relative to the first shaft body 311 until the first shaft body 311 is confined within the second upper locking section 4152. In this process, the second shaft body 312 and the second lower locking section 4162 Always touch, the second angle is greater than the first angle.

That is to say, both the first switching element 401 and the second switching element 402 will rotate at a certain angle, and the rotation angle of the second switching element 402 is greater than the rotation angle of the first switching element 401, the first switching element 401 and the second switching element 401 Relative movement will also occur between 402 and they will be staggered with each other.

It is understandable that the rotation process of the first switching element 401 and the second switching element 402 does not have a certain sequence, and the two can be rotated at the same time. For example, the first switching element 401 and the second switching element 402 are in a certain sequence. Synchronously rotate within the range of the rotation angle, and then the first switching element 401 and the second switching element 402 are staggered with each other.

In actual operation, the first switching element 401 and the second switching element 402 drive the first groove body 411 and the second groove body 412 to rotate relative to the first shaft body 311 and the second shaft body 312, respectively, and the first shaft body 311 separates from the first shaft body 311 and the second shaft body 312. The free section S1 abuts the first upper locking section 4132 and the first lower locking section 4142, that is, the first shaft body 311 is confined to the first upper locking section 4132 and the first lower locking section 4142 at the same time, and the second The shaft 312 is separated from the second free section S2 and abuts against the second upper locking section 4152 and the second lower locking section 4162, that is, the second shaft 312 is confined to the second upper locking section 4152 and the second lower locking section at the same time. At the same time, the movement of the second switching member 402 causes the fourth shaft 322 to escape from the fourth limiting section 4222.

It can be understood that when the first shaft body 311 is located at the first upper locking section 4132 and the first lower locking section 4142, since the first switching element 401 and the second switching element 402 are mutually staggered, they are originally overlapped with each other. The first upper free section 4131 and the first lower free section 4141 will also be staggered. At this time, the first upper free section 4131 and the first lower free section 4141 are mutually staggered to restrict the first shaft body 311 from being separated from the first upper locking section 4132. And the first lower locking section 4142 can ensure that the first shaft body 311 is always maintained at the first upper locking section 4132 and the first lower locking section 4142 while the door body 20 continues to be opened.

Similarly, when the second shaft body 312 is located at the second upper locking section 4152 and the second lower locking section 4162, since the first switching member 401 and the second switching member 402 are staggered, the originally overlapping first The second upper free section 4151 and the second lower free section 4161 will also be staggered. At this time, the staggered second upper free section 4151 and the second lower free section 4161 restrict the second shaft 312 from separating from the second upper locking section 4152 and The second lower locking section 4162 can ensure that the second shaft 312 remains at the second upper locking section 4152 and the second lower locking section 4162 while the door 20 continues to be opened.

In addition, the rotation angle of the second switching element 402 is greater than the rotation angle of the first switching element 401, that is, the second switching element 402 and the first switching element 401 are staggered with each other, which can further improve the relationship between the first hinge element 31 and the switching assembly 40. The locking effect ensures that the first shaft 311 is always maintained at the first upper locking section 4132 and the first lower locking section 4142, and the second shaft 312 is always maintained at the second upper locking section 4152 and the first lower locking section 4142. The second locking section is at 4162.

At the same time, when the first switching element 401 and the second switching element 402 move relatively, the distance between the third shaft 321 on the first switching element 401 and the fourth shaft 322 on the second switching element 402 occurs. The third shaft body 321 is always located in the third free section 4211, and the fourth shaft body 322 moves from the fourth limit section 4222 to the fourth free section 4221, that is, the fourth shaft body 322 departs from the fourth limit section 4222 .

19-22, 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 element 401 and the second switching element 402 are relatively stationary, and the third shaft 321 is at The third free section 421 moves, and the fourth shaft 322 moves on the fourth free section 4221.

Here, the range of the first opening angle α1 is approximately 80°-83°, the second opening angle α2 is approximately 90°, and the maximum opening angle α3 is greater than 90°, that is, the door body 20 is opened to 80°-83° During the process, the door body 20 is first displaced in the first direction X to avoid interference with the surrounding cabinets or walls during the opening process of the door body 20, and the auxiliary door body 20 opens, and finally reaches 80°～83°. After that, when the door body 20 continues to open to 90°, the switch assembly 40 moves to make the door body 20 replace the rotation axis and continue to rotate, that is, after 90°, the door body 20 uses the third shaft body 321 as the rotation axis relative to the box. The body 10 continues to rotate in place to further open the door body 20.

It can be understood that the angle is not limited to the above description.

It can be seen that this embodiment can effectively control the sequence switching of the first hinge member 31 and the second hinge member 32 through the unlocking and locking effects of the switching assembly 40 on the first hinge member 31 and the second hinge member 32, so that the door The body 20 can be stably opened.

It can be understood that when the door body 20 is in the closing process, that is, when the door body 20 starts to close from the maximum opening angle α3, the switching assembly 40 can also effectively control the sequence switching of the first hinge member 31 and the second hinge member 32, namely When the door body 20 is in the process of closing from the maximum opening angle α3 to the second opening angle α2, the third shaft body 321 moves in the third free section 4211, the fourth shaft body 322 moves in the fourth free section 4221, and switches The assembly 40 locks the first hinge member 31. When the door body 20 is in the process of closing from the second opening angle α2 to the first opening angle α1, the first switching member 401 and the second switching member 402 move relative to each other so that the first The hinge member 31 is disengaged from the limit of the switching assembly 40, and the fourth shaft 322 is limited in the fourth limit section 4222. The switching assembly 40 locks the second hinge member 32. When the door 20 is closed from the first opening angle α1 to In the process of fully closing, the first shaft 311 moves in the first free section S1, and the second shaft 312 moves in the second free section S2.

In other words, the closing process of the door body 20 and the opening process of the door body 20 are in the opposite sequence. The unlocking and locking effects of the switching assembly 40 on the first hinge member 31 and the second hinge member 32 can effectively control the door. The switching sequence of the first hinge member 31 and the second hinge member 32 during the opening and closing of the body 20.

In this embodiment, the distance between the initial position A1 and the front wall 21 is smaller than the distance between the stop position A2 and the front wall 21, and the distance between the initial position A1 and the side wall 22 is greater than the distance between the stop position A2 and the side wall 22.

Specifically, the distance between the center of the first shaft body 311 and the front wall 21 when the first shaft body 311 is at the initial position A1 is smaller than the distance between the center of the first shaft body 311 and the front wall 21 when the first shaft body 311 is at the stop position A2.

The distance between the center of the first shaft body 311 and the side wall 22 when the first shaft body 311 is located at the initial position A1 is greater than the distance between the center of the first shaft body 311 and the side wall 22 when the first shaft body 311 is located at the stop position A2.

The center of the first shaft body 311 and the front wall 21 are at a first distance, and the center of the first shaft body 311 and the side wall 22 are at a second distance. When the door 20 is opened, the first distance and the second distance are The spacing is variable.

When the door body 20 is in the process of opening from the closed state to the first opening angle α1, the first distance is increasing, and the second distance is decreasing. When the door body 20 is at the second opening angle α2, it continues to open to During the process of the maximum opening angle α3, both the first distance and the second distance remain unchanged.

Here, when the door body 20 is in the process of opening from the closed state to the first opening angle α1, the first distance shows an increasing trend, that is, corresponding to the movement of the door body 20 in the first direction X, and the second distance shows a decreasing trend, which corresponds to The door body 20 moves in the second direction Y.

In addition, in this embodiment, the first shaft body 311 and the third shaft body 321 are staggered from each other, so that it can be applied to a scene where a built-in cabinet or a refrigerator 100 has a small space.

With reference to FIG. 23, a simple schematic diagram of the refrigerator 100 embedded in the cabinet 200 is taken as an example for description.

In this embodiment, the box body 10 includes an opening 102 and a front end surface 103 arranged around the opening 102. The box body 10 also includes a receiving chamber S and an outer side surface 13 adjacent to the hinge assembly 30 and on the extension of the rotation path of the door body 20. The door body 20 includes a front wall 21 away from the containing chamber S and a side wall 22 always sandwiched between the front wall 21 and the containing chamber S. 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 closed state and is opened to the first opening angle α1, the door body 20 rotates about the first shaft body 311, and there is a first distance between the first shaft body 311 and the front end surface 103, 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, the door body 20 rotates around the third shaft body 321, and there is a second shaft between the third shaft body 321 and the front end surface 103. The second distance is greater than the first distance. In this way, the maximum opening angle of the fully built-in refrigerator 100 can be greatly increased.

In addition, there is a third distance between the first shaft body 311 and the outer side surface 13. 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, the third shaft body 321 and the outer side surface 13 There is a fourth distance between them, and the fourth distance is smaller than the third distance, which can further increase the opening degree of the box body 10.

The specific instructions are as follows:

In some movement tracks of the refrigerator 100, it can be considered that the door body 20 moves relative to the door body 20 with the first shaft body 311 and the third shaft body 321 as axes in sequence.

In this embodiment, the hinge assembly 30 further includes a second shaft body 312 matching the first shaft body 311 and a fourth shaft body 322 matching the third shaft body 321. To simplify the description, simply regard the door body 20 as the first The one shaft body 311 is used as the axis to rotate, and then the switching assembly 40 is switched to use the third shaft body 321 as the axis to rotate.

In actual operation, in order to improve the embedding effect, it is better to completely embed the refrigerator 100 into the cabinet 200. The refrigerator 100 is a freely embedded refrigerator, that is, the front end 201 of the cabinet 200 and the front wall 21 of the door 20 away from the cabinet 10 It is located on the same plane, or the front wall 21 of the door body 20 does not protrude from the front end 201 of the cabinet 200 at all.

In the prior art, all refrigerators are single-axis refrigerators, and a certain distance must be maintained between the rotation axis of the refrigerator and the side wall and front wall of the refrigerator. In this way, there can be enough space to satisfy foaming or other processes. The position of the rotation axis of the refrigerator is roughly at the position of the first shaft body 311 in Figure 23. In this case, after the single-axis refrigerator is embedded in the cabinet 200, the cabinet 200 is sandwiched between the front end 201 and the inner wall 202. 203 is arranged corresponding to the side edge 23 of the door body 20. When the door body 20 is opened, the side edge 23 will interfere with the door body 20 to limit the maximum opening angle of the door body 20. In order to ensure the normal opening of the door body 20, the prior art The usual method is to increase the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100. The gap roughly needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of the limited space.

With reference to Figure 23, the shaded area represents the door body 20 in the closed state. When the door body 20 is in the opening process, if the door body 20 always rotates around the first shaft body 311 (that is, the prior art), refer to Figure 23 Dotted line door 20', because the first shaft 311 is close to the front end 103, that is, the first shaft 311 is away from the front end 201 of the cabinet 200 at this time. When the door 20' is opened to a certain angle, the corners 203 of the cabinet 200 will change It interferes with the door body 20' to limit the maximum opening angle of the door body 20'.

In this embodiment, the third shaft body 321 is located on the first switching member 401. During the opening of the door body 20, the switching assembly 40 moves relative to the first hinge member 31 and the second hinge member 32 to make the third shaft body 321 gradually moves away from the front end surface 103, that is, the third shaft body 321 gradually moves toward the front end 201 of the cabinet 200, that is, at this time, the entire door body 20 moves away from the box body 10, refer to the solid line in FIG. 23 The interference effect of the door 20 and the corners 203 of the cabinet 200 on the door 20 is greatly reduced, and the corners 203 of the cabinet 200 will interfere with each other when the door 20 is opened to a larger angle, thereby greatly increasing the maximum opening angle of the door 20.

That is to say, in this embodiment, the switch assembly 40 can make the late door 20 rotate around the third shaft 321 as the axis, and the maximum opening of the door 20 can be effectively increased on the premise that the refrigerator 100 is freely inserted into the cabinet 200. The angle, thereby facilitating the user to operate the refrigerator 100, can greatly improve the user experience.

Moreover, in this embodiment, there is no need to increase the gap between the inner wall 202 of the cabinet 200 and the refrigerator 100, and a seamless connection between the refrigerator 100 and the cabinet 200 can be achieved, which greatly improves the embedding effect.

In addition, while the switching assembly 40 of this embodiment drives the third shaft 321 to gradually move toward the front end 201 of the cabinet 200, it also drives the third shaft 321 to gradually approach the inner wall 202 of the cabinet 200, that is, when When the door body 20 rotates with the third shaft body 321 as the axis, the third shaft body 321 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first shaft body 311 at this time. In this way, the door body 20 can be improved. The maximum opening angle can make the door 20 far away from the box body 10 to increase the opening degree of the box body 10, which facilitates the opening and closing of shelves, drawers, etc. in the box body 10, or in other words, facilitates the picking and placing of items.

Of course, the third shaft body 321 ultimately serving as the rotating shaft can also be located in other positions. For example, when the door body 20 rotates around the third shaft body 321, the third shaft body 321 at this time is compared with the first shaft. The body 311 is close to the front end 201 of the cabinet 200, and the third shaft 321 is farther away from the inner wall 202 of the cabinet 200 than the first shaft 311.

It can be understood 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 of the door body 20, which can effectively prevent the door body 20 from interfering with the cabinet 200 during the opening and closing process.

In addition, it should be noted that the specific shaft groove design can effectively control the movement trajectory of the door 20. In this embodiment, the box 10 includes the pivot side P connected to the hinge assembly 30. When the door 20 is in the During the opening process, the hinge assembly 30 at least drives the door body 20 to move from the pivoting side P toward the accommodating chamber S, so as to prevent the door body 20 from interfering with the surrounding cabinets or walls during the opening process. The specific design can refer to the following implementation.

The following is a brief introduction with reference to FIG. 24 The hinge assembly 30' is located below the door body 20 and the box body 10.

The difference between the lower hinge assembly 30' and the upper hinge assembly 30 is that the first hinge part 31' of the lower hinge assembly 30' has a convex portion 313', and the second hinge part 32' has a corresponding hook 323', The hook 323' is an elastic member. When the door body 20 is in the closed state, the convex portion 313' acts on the hook 323' to deform to make the door body 20 and the box body 10 closely fit. When the door body 20 is in the opening process, The door body 20 drives the hook 323' to move, and the hook 323' is deformed and detaches from the convex portion 313'.

In other words, when the door body 20 is in the closed state, there is an interference fit between the convex portion 313' and the hook 323', which enhances the closing effect of the door body 20.

It should be noted that, since the switching assembly 40' is connected between the first hinge part 31' and the second hinge part 32', the second hinge part 32' also includes an extension 324' that passes through the switching assembly 40' in the thickness direction, The extension section 324' is connected to the hook 323', so that the hook 323' is arranged horizontally and can be matched with the convex portion 313'.
