[0038] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0039] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In addition, the terms "first", "second", "third", "fourth", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0040] One embodiment of the present invention provides a refrigerator, comprising any one of the following storage components.

[0041] The refrigerator may include storage compartments of different temperature zones, and a refrigerator door for opening and closing the storage compartments. Usually, a refrigerator is provided with a refrigerating compartment with a temperature higher than 0 degrees Celsius and a freezing compartment with a temperature lower than 0 degrees Celsius, and a refrigerator door for opening and closing the corresponding refrigerating compartment and freezing compartment. In one embodiment, the storage assembly may be used to form the refrigerator door and the refrigerating compartment or the freezing compartment.

[0042] One embodiment of the present invention provides a storage component, such as Figure 1 and Figure 2 As shown, it includes a box body 100, a door body 200 and a hinge assembly 300. The door body 200 is pivotally connected to the opening side 10 of the box body 100 through the hinge assembly 300, so as to realize the opening and closing of the internal storage space of the box body 100 by the door body 200.

[0043] The hinge assembly used to realize the opening and closing of the door body, when the storage assembly is arranged in the vertical direction, can include an upper hinge assembly located on the side of the door body 200 opposite to the upper end, and a lower hinge assembly located on the side of the lower end of the door body 200.

[0044] In one embodiment, the upper hinge assembly and the lower hinge assembly can be configured as the same structure. In one embodiment, the upper hinge assembly and the lower hinge assembly can have different structures. The latter embodiment is adopted in the preferred embodiment of the present invention, combined with Figure 1 As shown, the storage assembly includes an upper hinge assembly 300 and a lower hinge assembly 500. Based on this, if not particularly emphasized, the hinge assembly 300 described herein may indicate one of the upper hinge assembly or the lower hinge assembly, or only indicate the upper hinge assembly.

[0045] Figure 2 is a top view of the storage assembly when the door body 200 is opened to a second angle, Figure 3 yes Figure 2 A partial enlarged view of area A in the middle. It can be understood that Figures 4 to 6 The same corresponds to Figure 2The partial enlarged view of the area A in the middle indicates the states when the door body 200 is opened to other angles.

[0046] Figure 3 An embodiment of the present invention is shown, in which a hinge assembly 300 includes a first shaft 31 , a second shaft 32 , and a hinge slot 2 matched with the first shaft 31 and the second shaft 32 .

[0047] In one embodiment, the first axis 31 and the second axis 32 jointly control the rotation state of the door body 200, and in particular, the first axis 31 and the second axis 32 can jointly control the state of the door body 200 rotating with different rotation centers. In some embodiments, the first axis 31 and the second axis 32 can also be used to control the translation state of the door body 200, such as translation toward or away from one side of the box body 100, or translation toward or away from the opening side. Specifically, the reason why the first axis 31 and the second axis 32 form the above control is the relative position constraint relationship between the two axes and the hinge slot 2, and the relative position constraint relationship between the two axes.

[0048] In one embodiment, the hinge slot 2 includes at least two slot sections. For example, Figure 3 The first slot section 2A and the second slot section 2B shown in FIG. 2A are shown in FIG. 2B ; the first shaft 31 may have a stage of moving along the first slot section 2A or at least being located in the first slot section 2A, and the second shaft 32 may have a stage of moving along the second slot section 2B or at least being located in the second slot section 2B, so that the door body 200 can be pivoted open. For example, Figure 5 The second slot segment 2B and the third slot segment 2C are shown in the figure; the first axis 31 may exist in a stage of moving along the third slot segment 2C or at least being located in the third slot segment 2C, and the second axis 32 may exist in a stage of moving along the second slot segment 2B or at least being located in the second slot segment 2B, so that the door body 200 can be pivoted open.

[0049] The ends of the two slot sections are connected. Figure 3 The first slot segment 2A is connected to the end of the second slot segment 2B, and specifically, the end of the first slot segment 2A is connected to the head of the second slot segment 2B. Figure 5 The ends of the second slot segment 2B and the third slot segment 2C are connected, and specifically, the head of the second slot segment 2B is connected to the head of the third slot segment 2C. Figure 4 The ends of the first slot segment 2A and the third slot segment 2C are connected, and specifically, the end of the first slot segment 2A is connected to the head of the third slot segment 2C.

[0050] The two slot sections extend in different directions. The different extension directions can be interpreted as different overall directions. Figure 4 The first slot section 2A and the second slot section 2B have different shapes, curvatures, arcs, and curvature radii; for example Figure 4 The deflection directions of the first slot segment 2A and the third slot segment 2C are different.

[0051] During the process of opening the door body 200, there is a stage between the first shaft 31 and the second shaft 32 relative to the door body 200: the second shaft 32 is located in one of the two groove sections, and the first shaft 31 moves along the other of the two groove sections. In this way, the second shaft 32 and the first shaft 31 at least have different movement trends, forming a restraining relationship between each other, and combined with the connection of the ends of the two groove sections, the smoothness of door opening can be improved, the sense of frustration when opening the door can be alleviated, and the door opening process can be maintained stable.

[0052] In one embodiment, when the second shaft 32 moves along one of the two groove sections relative to the door body 200, the center point of the shaft moves to form a trajectory line; for example, when the second shaft 32 moves in the second groove section 2B, the center point of the second shaft 32 or the projection of its center line on the bottom of the hinge groove 2 moves accordingly to form a second trajectory line 6B. When the first shaft 31 moves along the other of the two groove sections relative to the door body 200, the center point of the shaft moves to form another trajectory line; for example, when the first shaft 31 moves in the first groove section 2A, the projection of the center point of the first shaft 31 or its center line on the bottom of the hinge groove 2 moves accordingly to form a first trajectory line 6A; for example, when the first shaft 31 moves in the third groove section 2C, the center point of the first shaft 31 or the projection of its center line on the bottom of the hinge groove 2 moves accordingly to form a third trajectory line 6C.

[0053] Furthermore, based on the different extension directions of the two slot segments, the extension directions or overall shapes of the above-mentioned trajectory lines are different. For example, the first trajectory line 6A and the third trajectory line 6C are both circular arcs, and the second trajectory line 6B is an irregular curve or a quasi-elliptical arc. For example, when the user stands facing the door body, the third trajectory line 6C deflects away from the user relative to the first trajectory line 6A, and the second trajectory line 6B deflects towards the user relative to the first trajectory line 6A.

[0054] In one embodiment, the first shaft 31 and the second shaft 32 are fixed to the box body 100 to take into account the cleaning, assembly, life and processing technology of the shaft groove; correspondingly, the hinge groove 2 is fixed to the door body 200, which is convenient for adjusting the structure of the hinge groove 2 and even realizing the configuration of a replaceable hinge groove 2, while taking into account the advantages of shaft groove cleaning, assembly, life and processing technology.

[0055] like Figure 4 and Figure 3 , Figures 5 and 6As shown, the door body 200 includes a door side wall 21 close to the side environment part 400 when the door is closed. In other words, the storage assembly can be arranged close to the side environment part 400, and can be arranged on one side of the side environment part 400, and the door body 200 and the box body 100 are arranged on the same side of the side environment part 400. The side environment part 400 can be a wall, a cabinet wall or even other door bodies or box body structures. That is, the storage assembly provided by the present invention can be applied to household appliances that need to be attached to other wall surfaces, for example, it can be applied to embedded equipment.

[0056] The first axis 31 has a first distance from the door sidewall 21, and the second axis 32 has a second distance from the door sidewall 21. During the opening process of the door body 200, there is a stage in which the sum of the first distance and the second distance decreases.

[0057] In one case, both the first distance and the second distance decrease; for example, the first shaft 31 moves in the first slot section 2A, and the second shaft 32 moves in the second slot section 2B. In one case, the magnitude of the decrease in the first distance is greater than the magnitude of the increase in the second distance; in one case, the magnitude of the increase in the first distance is less than the magnitude of the decrease in the second distance.

[0058] In this way, the door side wall 21 moves relatively close to the first axis 31 and the second axis 32, which is equivalent to the door side wall 21 moving away from the side environment part 400, so that when the door body is pivoted open, it moves horizontally close to the opening side to avoid interference with the side environment part 400, which can be applied in embedded scenarios.

[0059] In one embodiment, when the door is closed, the first shaft 31 is located on a side of the second shaft 32 away from the door side wall 21 .

[0060] In one embodiment, continue as Figure 3 and Figure 4 As shown, the hinge slot 2 includes a first slot segment 2A and a second slot segment 2B connected end to end; the end of the first slot segment 2A is connected to the head of the second slot segment 2B. The first slot segment 2A and the second slot segment 2B extend in different directions; the first slot segment 2A is in an arc shape or approximately in an arc shape, and the second slot segment 2B is in an irregular curve shape, an elliptical arc shape, or approximately in an elliptical arc shape.

[0061] During the process of opening the door body 200, there is a stage in which the first shaft 31 moves along the first slot segment 2A relative to the door body 200. During the process of opening the door body, there is a stage in which the second shaft 32 moves along the second slot segment 2B relative to the door body 200. In one embodiment, during the process of opening the door body 200, the above two stages exist at the same time, and the two stages are performed simultaneously.

[0062] Since the first slot section 2A and the second slot section 2B extend in different directions, the two axes of motion restrict each other, and the door body 200 can be opened smoothly. Since the first slot section 2A and the second slot section 2B are connected end to end, the extending direction of the two slot sections as a whole can be adjusted so that the door body 200 can be translated to a certain extent while pivoting. Since the first slot section 2A and the second slot section 2B are connected end to end, the door body 200 can be opened continuously and smoothly.

[0063] The door body 200 includes a door side wall 21 that is adjacent to the side environment member 400 when the door is closed.

[0064] In one embodiment, when the door body 200 opens from the first angle α1 to the second angle α2, the first shaft 31 moves from the first guide position P1 to the second guide position P2 relative to the door body 200. The second guide position P2 is located on the side of the first guide position P1 close to the door side wall 21.

[0065] The first guide position P1 is a slot in the hinge slot 2; the first guide position P1 is a slot in the first slot section 2A; the first guide position P1 points to the head of the first slot section 2A. The second guide position P2 is a slot in the hinge slot 2; the second guide position P2 is a slot in the second slot section 2B, the second guide position P2 points to the head of the second slot section 2B; the second guide position P2 is a slot in the first slot section 2A, the second guide position P2 points to the end of the first slot section 2A.

[0066] In one embodiment, when the door body 200 opens from the first angle α1 to the second angle α2, the second shaft 32 moves from the first driving position Q1 to the second driving position Q2 relative to the door body 200. The second driving position Q2 is located on the side of the first driving position Q1 close to the door side wall 21.

[0067] The first driving position Q1 is a slot in the hinge slot 2; the first driving position Q1 is a slot in the second slot section 2B, and the first driving position Q1 points to the head of the second slot section 2B; the first driving position Q1 is a slot in the first slot section 2A, and the first driving position Q1 points to the end of the first slot section 2A. The second driving position Q2 is a slot in the hinge slot 2; the second driving position Q2 is a slot in the second slot section 2B; the second driving position Q2 points to the end of the second slot section 2B.

[0068] In this way, relative to the door body 200, both axes move closer to the door side wall 21. When the door body 200 pivots open, there is a movement component along the first direction F1 closer to the opening side relative to the box body 100, thereby avoiding the side environmental component 400 on the other side.

[0069] The first direction F1 may be defined as a direction perpendicular to the door side wall 21 when the door is closed.

[0070] The first driving position Q1 and the second guiding position P2 point to the same position of the hinge slot 2 .

[0071] The second driving position Q2 is located at a side of the first guiding position P2 close to the door side wall 21 .

[0072] In one implementation, the first shaft 31 and the second shaft 32 are fixed to the box body 100 ; correspondingly, the hinge slot 2 is fixed to the door body 200 .

[0073] The hinge assembly 300 cooperates, especially the first shaft 31, the second shaft 32 cooperates with the hinge slot 2, so that the door body 200 moves inward relative to the opening side at least during the process of opening from the first angle α1 to the second angle α2. The hinge assembly 300 cooperates, especially the first shaft 31, the second shaft 32 cooperates with the hinge slot 2, so that the door body 200 moves inward relatively away from the side environment member 400 at least during the process of opening from the first angle α1 to the second angle α2.

[0074] The door body 200 includes a door front wall 22 facing away from the box body 100 when the door is closed.

[0075] In one embodiment, when the door body 200 opens from the first angle α1 to the second angle α2, the first shaft 31 moves from the first guide position P1 to the second guide position P2 relative to the door body 200.

[0169] When the door 200 is opened from the third angle α3 to the maximum angle, the first shaft 31 moves from the third guide position P3 to form a third track variable 6C'. The third track variable 6C' is combined with the third track 6C to form a new third track 6C; the length of the new third track 6C is positively correlated with the maximum angle.

[0170] The larger the maximum angle is set, the longer the length of the new third track line 6C is; the smaller the maximum angle is set, the shorter the length of the third track line 6C is.

[0171] The trajectory center of the third trajectory line variable 6C′ is located at the second axis 32 or the second driving position Q2.

[0172] The door outer edge 24 continues to move to the fourth outer edge position W4. The fourth outer edge position W4 is located on the side of the third outer edge position W3 close to the box body 100.

[0212] A boss structure 530 is formed at the position where the first lower shaft 531 and the second lower shaft 532 are connected to the lower support plate 522. The boss structure 530 is arranged along the circumference of the two shafts to increase the width of the shaft in the radial direction and improve the structural strength.

[0213] The first angle α1 is one of 0 degrees to 10 degrees; the first angle α1 is 0 degrees. The second angle α2 is one of 30 degrees to 60 degrees; the second angle α2 is 45 degrees.
