[0003] In a type of product, support parts are first mounted on two side walls of the cover plate, the support parts are provided with support shafts, the support shafts pass through accommodating spaces arranged in the cover plate, such as slots or holes, the support parts are then fixed on the side walls of the storage chamber, and thereby the cover plate can rotate around the support shafts.

[0004] However, in another type of product, the support parts have to be mounted on the side walls of the storage chamber in advance. For example, the support parts are fixed in a foam layer between a shell and a liner of the refrigeration appliance in advance, and pass through the side walls of the storage chamber to extend into the storage chamber, so the support parts must be assembled on the refrigeration appliance first. The support shafts which correspond to the positions of the two side walls are axially projected into the storage chamber, so that the support shafts cannot be directly inserted into the accommodating spaces along an axial direction, and as a result, a barrier is created to the installation of the cover plate.

SUMMARY

[0005] One objective of the present application is to provide a refrigeration appliance which is feasible and convenient to assemble.

[0006] In order to solve the above-mentioned object, the present application provides a refrigeration appliance. The refrigeration appliance comprises a storage chamber, a cover plate arranged at the position of an opening of the storage chamber, and connecting assemblies connecting side walls of the storage chamber with the cover plate, each connecting assembly comprises an accommodating space and a support shaft arranged in the accommodating space, and the cover plate can rotate between a first position (horizontal position) and a second position (vertical position) around the support shafts; a circumferential wall of each accommodating space is provided with a gap, and the support shafts are suitable for entering from the gaps and being defined within the accommodating spaces.

[0007] During assembly, the gaps can be aligned with the side surfaces of the support shafts, so that the support shafts can enter the accommodating spaces via the gaps, and thereby the cover plate can be quickly and conveniently installed on the side walls of the storage chamber. Especially, when the support shafts have been mounted on the corresponding side walls of the storage chamber in advance, the cover plate adjoins the corresponding side walls of the storage chamber, so that the circumferential walls of the accommodating spaces are in installation interference with the support shafts, as a result, the support shafts cannot be directly inserted into the corresponding accommodating spaces along the axial direction, but the support shafts can be easily installed into the accommodating spaces via the gaps, and thereby the feasibility and convenience of the assembly of the cover plate are increased.

[0008] Preferably, for the connecting assembly corresponding to at least one of the two side walls of the storage chamber, the circumferential wall of the accommodating space may be provided with the gap. For example, the connecting assembly corresponding to only one side wall may be provided with a gap, or the connecting assemblies corresponding to the two side walls are both may be provided with gaps.

[0009] Preferably, the circumferential wall of the accommodating space may comprise three side accommodating walls that face the inside, top wall and bottom wall of the storage chamber in the vertical position, and the gap may be formed in one of the three side accommodating walls. At the vertical position, the gaps may be formed in the three side accommodating walls facing the inside, top wall and bottom wall of the storage chamber, and when a user opens a door of the refrigeration appliance, the accommodating walls in which the gaps are formed are invisible, thereby enhancing the aesthetic feeling of the user.

[0010] Preferably, the width of the gap may be less than or equal to the maximum diameter of the support shaft. The width of the gap means the distance between two oppositely arranged boundaries of the gap. Thus, a certain magnitude of interference may exist between the gap and the support shaft. During assembly, strength needs to be exerted, so that the support shaft can overcome the magnitude of interference to be squeezed into the gap until the support shaft arrives in the accommodating space. Thus, at least when being initially installed into the accommodating space, the support shaft may not be easily get out of the gap anymore, thereby keeping the stability of initial installation. Especially, in the process of operation, depending on the certain magnitude of interference between the support shaft and the gap, the support shaft may be prevented from getting out of the gap.

[0011] Preferably, the connecting assembly may further comprise a stopper fixed in the gap or disposed between the support shaft and the accommodating space to cover the gap. Thus, the stopper may block the support shaft from getting out of the gap.

[0012] Preferably, the stopper may be tightly fitted with the gap, and thereby may be fixed in the gap. In this embodiment, the assembly of the stopper may be simple, the stopper may be made by using a material suitable for elastic deformation, such as plastic, and thereby may be elastically deformed in the process of being squeezed into the gap to be tightly fixed in the gap.

[0013] Preferably, the stopper may be provided with claws projected into the accommodating space, an inner wall surface of the accommodating space may be provided with a slot, and the claws may be fastened in the slot. The claws may enhance the fixing effect of the stopper, and prevent the stopper from falling off.

[0014] Alternatively, the gap may be provided with two side boundaries which are oppositely arranged, and each boundary may comprise a first surface facing the outside of the accommodating space, a second surface located on the side of the first surface far from the accommodating space, and a third surface located on the side of the first surface close to the accommodating space, and there are angles between the first surface and the second surface and between the first surface and the third surface; and the stopper fits the boundaries.

[0015] In this case, for each boundary of the gap, the first surface may be connected with the second surface and the third surface, forming a step portion. Correspondingly, the stopper may match the boundaries, it may be that the stopper is provided with step sections which match the step portions, and the two are in tight contact. Such a step structure may enhance the contact area between the stopper and the boundaries, the stopper may be more tightly defined in the gap, and thereby the stopper is steadier, not easily getting out of the gap.

[0016] Preferably, the accommodating space may be arranged on the cover plate and may be a through hole having openings at two ends, and the support shaft passes through the opening of one end and the stopper is mounted between the support shaft and the accommodating space from the opening of the other end.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objective, features and advantages of the present application clearer and easier to understand, the specific embodiments of the present application will be described in detail with reference to the accompanying drawings below.

First Embodiment

[0027] Refer to FIG. 1, a refrigeration appliance, such as a refrigerator, comprises a storage chamber 1 a, a cover plate 2 arranged at the position of an opening 1aa of the storage chamber 1a, and connecting assemblies 3 connecting side walls 10 of the storage chamber 1a with the cover plate 2. The refrigeration appliance may further comprise shelves, storage containers and so on (not shown in the drawing) which are contained in the storage chamber 1a, and refer to FIG. 2 and FIG. 3, each connecting assembly 3 may comprise an accommodating space 3a and a support shaft 30 arranged in the accommodating space 3a, for example, the accommodating space 3a can be arranged on the cover plate 2 and the support shaft 30 can be arranged on the side wall 10 of the storage chamber 1a. The cover plate 2 can rotate between the first position (horizontal position) and the second position (vertical position) around the support shaft 30, for example, at the vertical position shown in FIG. 1, the cover plate 2, which is located at the position of the opening 1aa of the storage chamber 1 a, can cover the shelves to block food on the shelves from dropping. When food needs to be taken out of or stored into the storage chamber 1 a, the arranged cover plate 2 is turned out of the storage chamber 1 a from the second position (vertical position) shown in FIG. 1 to the first position (horizontal position) to be exposed from the shelves. A circumferential wall 31 of the accommodating space 3a is provided with a gap 31 a, and the support shaft 30 is suitable for entering via the gap 31 a and being defined in the accommodating space 3a.

[0028] In the process of assembly, the cover plate 2 is arranged at the position of the opening 1aa of the storage chamber 1a, so that the gap 31a is aligned with the side surface of the support shaft 30; the support shaft 30 then enters the accommodating space 3a via the gap 31 a (refer to FIG. 3), and thereby the cover plate 2 is quickly and conveniently mounted on the side wall 10. Especially, when the support shaft 30 has been mounted on the corresponding side wall 10 in advance, the cover plate 2 adjoins the corresponding side wall 10 of the storage chamber 1 a, so that the circumferential wall 31 of the accommodating space 3a interferes with the support shaft 30, so that the support shaft 30 cannot be directly inserted into the corresponding accommodating space 3a along the axial direction, and by arranging the gap 31 a in the circumferential wall 31, the support shaft 30 can be easily installed into the accommodating space 3a via the gap 31 a.

[0029] Refer to FIG. 1 and FIG. 2, among the two side walls 10 of the storage chamber 1 a, for the connecting assembly 3 corresponding to the right side wall 10, the circumferential wall 31 of the accommodating space 3a may be provided with the gap 31 a (the gap in FIG. 1 is downwardly formed and is invisible, please refer to FIG. 2). Refer to FIG. 3, for the connecting assembly 3' corresponding to the left side wall 10', the circumferential wall 31' of the accommodating space 3a makes a circle along a circumferential direction without forming a gap. During assembly, the left support shaft (not shown in FIG. 3) can be inserted into the accommodating space along the axial direction, however, the right support shaft 30 shown in FIG. 1 can only be inserted into the accommodating space 3a via the gap 31 a, and this can make the advantages of the present technical solution more outstanding.

[0030] In a modified solution, only for the connecting assembly corresponding to the right side wall, the circumferential wall of the accommodating space may be provided with a gap, or for the connecting assemblies corresponding to the left side wall and the right side wall, the circumferential wall of each accommodating space is provided with a gap.

[0031] Therefore, for the connecting assembly corresponding to at least one side wall, the circumferential wall of the accommodating space is provided with the gap.

[0032] Refer to FIG. 1, the circumferential wall 31 of the accommodating space 3a is provided with a side accommodating wall which faces a bottom wall 11 of the storage chamber 1a at the vertical position, and refer to FIG. 2, the side accommodating wall serves as a first accommodating wall 311, wherein the gap 31a is formed in the first accommodating wall 311. When the cover plate 2 rotates from the second position (vertical position) to the first position (horizontal position) around the support shaft 30, then the first accommodating wall 311 arrives at a position facing the inside of the storage chamber 1a from the position facing the bottom wall 11 of the storage chamber 1a. During assembly, the cover plate 2 can be horizontally placed first, so that the gap 31 a faces the inside of the storage chamber 1 a and is aligned with the support shaft 30, and the cover plate 2 is then pushed from the outside into the storage chamber 1 a until the support shaft 30 is completely defined in the accommodating space 3a (refer to FIG. 3). Or, during assembly, the cover plate 2 can be vertically placed first, so that the gap 31 a faces the bottom wall 11 of the storage chamber 1 a and is aligned with the support shaft 30, and the cover plate 3 is then downwardly moved until the support shaft 30 enters the accommodating space 3a.

[0033] On one hand, there are a variety of assembly strategies to choose, and operation is easy; on the other hand, at the second position (vertical position), the first accommodating wall 311 faces the bottom wall 11 of the storage chamber 1 a and is invisible, and when a user opens a door of the refrigeration appliance, the gap 31a will not affect the appearance. At the first position (horizontal position), the first accommodating wall 311 faces the inside of the storage chamber 1a, and the gap 31a will not affect the aesthetic feeling of the user.

[0034] Refer to FIG. 2, the width of the gap 31 a is less than or equal to the maximum diameter of the support shaft 30, wherein the width of the gap 31 a means the distance between two oppositely arranged boundaries 312 of the gap 31 a. Thus, a certain magnitude of interference exists between the gap 31 a and the support shaft 30. During assembly, strength needs to be exerted, so that the support shaft 30 can overcome the magnitude of interference to be squeezed into the gap 31 a until the support shaft 30 arrives in the accommodating space 3a (refer to FIG. 3). Thus, at least when being initially installed into the accommodating space 3a, the support shaft 30 cannot easily get out of the gap 31 a anymore, thereby keeping the stability of initial installation.

[0035] In a preferred embodiment, refer to FIG. 3, the connecting assembly 3 may further comprises a stopper 32. Refer to FIG. 2, the stopper 32 is arranged between the support shaft 30 and the accommodating space 3a to cover the gap 31 a; while a certain magnitude of interference exists between the gap 31 a and the support shaft 30 for blocking the support shaft 30 from getting out, the stopper 32 can better block the support shaft 30 from getting out of the gap 31a, and this can ensure that in the long-term operation process of the cover plate 2, the support shaft 30 can be stably and steadily fitted with the accommodating space 3a without easily getting out.

[0036] The accommodating space 3a can be arranged on the cover plate 2 and is a through hole with openings at both ends. During assembly, the support shaft 30 can pass through the opening of one end, and then the stopper 32 is then installed between the support shaft 30 and the accommodating space 3a from the opening of the other end. As shown in FIG. 3, the left accommodating space 3a' is a slot with an opening at only one end, and during assembly, the support shaft (not shown in the drawing) can be directly inserted into the slot along the axial direction.

[0037] The stopper 32 may be arranged as a shaft sleeve, and is tightly fitted with the accommodating space 3a for fixing. In addition, the shaft sleeve is in clearance fit with the support shaft 30, and a moving clearance for the support shaft 30 is reserved. Besides, in another modified embodiment, the shaft sleeve may be arranged to fixedly sheathe the support shaft, for example, forming overtight fit, and this is equivalent to an increase in the maximum diameter of the support shaft, thus preventing the support shaft from getting out of the gap.

[0038] Besides, in another modified embodiment, the connecting assembly may not comprise the stopper, but only depends on the magnitude of interference between the gap and the support shaft to achieve the anti-separation arrangement of the support shaft.

[0039] Refer to FIG. 1, the cover plate 2 is provided with an outer wall surface 20 facing the outside of the storage chamber 1a at the vertical position; refer to FIG. 3, external projections 21 are projected from the outer wall surface 20, and the through holes (the accommodating spaces 3a) are formed in the external projections 21. This can prevent the through holes from being directly formed in the cover plate 2 to damage the cover plate 2.

[0040] Refer to FIG. 4, the refrigeration appliance may further comprise a support part 4, and the support part 4 extends into the storage chamber 1a from the side wall 10 of the storage chamber 1 a (refer to FIG. 2). The support shaft 30 is arranged on the support part 4, at least at the second position (vertical position) and the first position (horizontal position), referring to FIG. 1, the cover plate 2 can be supported by the support part 4 (in FIG. 1, the support part is covered and therefore is invisible) to keep stable. Especially at the vertical position, the support part 4 is covered by the cover plate 2 and therefore is invisible, so the user can have a good aesthetic feeling when opening the door. The fixed end of the support part 4 is located between the shell and liner of the refrigeration appliance and limited, and the free end of the support part 4 passes through the side wall 10 and extends into the storage chamber 1 a.

[0041] The support shaft 30 can be arranged at the end, close to the outside of the storage chamber 1a, of the support part 4, so that it is possible to enable the cover plate 2 to cover the support part 4 at the vertical position.

Second Embodiment

[0042] Refer to FIG. 5, the accommodating space 5a may be a slot, and refer to FIG. 6, the accommodating space 5a (in FIG. 6, the accommodating space is covered and therefore is invisible) faces the side wall 10 of the storage chamber 1 a on the same side.

[0043] Refer to FIG. 7, the stopper 52 can be fixed in the gap 5b to play the role of blocking the support shaft (not shown in the drawing) from getting out of the gap 5b. The stopper 52 may be in tight fit with the gap 5b and thereby can be fixed in the gap 5b.

[0044] Refer to FIG. 8, the gap 5b is provided with two oppositely arranged side boundaries 51. Taking one of the side boundaries 51 as an example, the boundary 51 comprises a first surface 511 facing the outside of the accommodating space 5a, a second surface 512 located on the side of the first surface 511 far from the accommodating space 5a, and a third surface 513 located on the side of the first surface 511 close to the accommodating space 5a, and there are angles between the first surface 511 and the second surface 512 and between the first surface 511 and the third surface 513. Thereby the second surface 512 and the third surface 513 are located on two sides of the first surface 511 and connected to the first surface 511, and thereby a step portion is formed on the boundary 51. The stopper 52 is provided with side wall surfaces which match the boundaries 51, so that the stopper 52 keeps matching with the boundaries 51 when fixed in the gap 5b. As the stopper 52 is fitted with the gap 5b by means of the step-like portions, the contact area of the two can be enlarged, so that the stopper 52 can be more tightly defined in the gap 5b without easily getting out.

[0045] The stopper 52 may be provided with claws 521, the claws 521 are projected into the accommodating space 5a, an inner wall surface 514 of the accommodating space 5a may be provided with a slot 5c, and refer to FIG. 7, the claw 520 may be fastened in the slot 5c (in FIG. 7, the slot is covered by the claws 520). Thereby the claws 520 have a limiting effect, so that the stopper 52 can better keep fixed and cannot easily get out.

[0046] Refer to FIG. 8, the stopper 52 is provided with two claws 520 which respectively correspond to the positions of the two side boundaries 51. During assembly, when sliding by the boundary 51 of the same side and sliding by the inner third surface 513, each claw 520 is squeezed by the third surface 513 to elastically deform, and after sliding by the third surface 513, the claw 520 is restored to the original state and fastened in the slot 5c.

[0047] Refer to FIG. 5, the circumferential wall of the accommodating space 5a comprises a second accommodating wall 515 which faces the inside of the storage chamber at the vertical position, and the gap 5b is formed in the second accommodating wall 515. Thus, at the vertical position, it is possible that the second accommodating wall 515 can be covered by the cover plate 6 and is invisible, so enhancing the aesthetic feeling of the user.

[0048] Further, the cover plate 6 is provided with plate wall surfaces 60; refer to FIG. 6, the plate wall surfaces 60 may face the side walls 10 of the storage chamber 1a, the accommodating spaces 5a may be arranged on the cover plate 6, the accommodating space 5a (in FIG. 6, the accommodating space is invisible) may extend along the width direction of the refrigeration appliance to be flushed with the plate wall surface 60, and thus the projection for forming the accommodating space 5a is prevented from protruding out of the plate wall surface 60 and thereby is prevented from interfering with the side wall 10. Besides, in another embodiment, the accommodating space may be arranged on the side of the plate wall surface facing away from the side wall.

Third Embodiment

[0049] Refer to FIG. 9, a support part 11 is formed on the side wall 10 of the storage chamber 1 a, and the support part 11 is provided with a projection 12 projected away from the side wall 10. Refer to FIG. 10, the projection 12 is provided with an accommodating space 7a, so that the accommodating space 7a is arranged on the side wall 10 of the storage chamber 1 a, and a gap 7b is upwardly formed. Correspondingly, refer to FIG. 11, the support shaft 80 is arranged on the cover plate 8, and can downwardly drop into the gap 7b and then get into the accommodating space 7a.

[0050] At this moment, refer to FIG. 10, the circumferential wall of the accommodating space 7a may further comprise a third accommodating wall 71 which faces the top wall of the storage chamber 1a at the vertical position, and the gap 7b is formed in the third accommodating wall 71. Thus, at the vertical position, the gap 7b cannot be easily seen.

[0051] The gap 7b is defined by two elastic pieces 72, the two elastic pieces 72 are suitable for extending so that the gap 7b opens to let the support shaft 80 (refer to FIG. 9) to pass through the gap 7b, and suitable for being restored to the original state after the support shaft 80 enters the accommodating space 7a from the gap 7b, consequently, the width of the gap 7b is reduced to the width of an initial shrunk gap, and the shrunk gap limits the support shaft 80, thus preventing it from getting out.
