The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

A shelf assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

A shelf assembly 100 according to an embodiment of the first aspect of the present invention, as shown in fig. 1-4, comprises: a main shelf 10, a slide rail 20 and a slide bracket 30.

The slide rail 20 includes a connected cross rail section 20-1 and side rail section 20-2, the cross rail section 20-1 extending laterally, and the cross rail section 20-1 being disposed above or below the main shelf 10, the side rail section 20-2 being connected to the main shelf 10.

The slide bracket 30 is slidably coupled to the slide rail 20, and the slide bracket 30 is slidable between a deployed position and a stowed position. As shown in fig. 2, the sliding bracket 30 is positioned on the cross rail section 20-1 in the deployed position, and the object is adapted to be placed transversely on the sliding bracket 30 when the sliding bracket 30 is in the deployed position. The sliding bracket 30 may be located on the cross rail section 20-1 or the side rail section 20-2 in the storage position, without limitation. As in the example of fig. 3, the sliding bracket 30 has a stowed position on the side rail section 20-2.

Depending on the nature of the object, the main shelf 10 may be provided with relatively large or heavy objects and the sliding brackets 31 may be provided with relatively slender or soft flat objects. It should be noted that, in actual use, the shapes of the main shelf 10 and the sliding bracket 31 for placing objects are not limited, for example, objects with smaller volume may be placed on the sliding bracket 31, and people may flexibly adjust according to the use situation of the shelf assembly 100. For simplicity of description, the structure of the shelf assembly 100 will be described below by taking the example of placing a wide object on the main shelf 10 and a slender object on the sliding bracket 31.

The sliding bracket 30 is arranged, so that a cylinder (such as a chopstick cage) is not required to be additionally arranged in the main shelf 10 to vertically arrange elongated objects, space is reserved for arranging more wide objects on the main shelf 10, and the problem of insufficient arrangement positions of the wide objects on the main shelf 10 is solved.

Wherein the slide rail 20 comprises a transverse rail section 20-1 extending transversely, and the sliding bracket 30 can enable the slender object to be transversely arranged on the sliding bracket 30 when the sliding bracket 30 is positioned on the transverse rail section 20-1. This eliminates the need to leave excessive height above or below the primary shelf 10 to accommodate elongated objects, thereby greatly increasing the space utilization of the shelf assembly 100.

The sliding bracket 30 can be switched between the unfolding position and the storage position by sliding connection with the sliding rail 20, and the operation is labor-saving and convenient, the sliding bracket 30 does not need to be disassembled to be stored, and the sliding bracket 30 is prevented from being lost.

When the cross rail section 20-1 of the sliding bracket 30 is located above the main shelf 10, the sliding arrangement of the sliding bracket 30 allows the position thereof to be switched, and interference of the sliding bracket 30 with the object on the main shelf 10 can be reduced. In addition, when the sliding bracket 30 is not required, it can be received so as to give the main shelf 10 a higher placing space.

It will be appreciated that for better placement of cutlery, the sliding brackets 30 are generally made of hard materials, while for ease of sliding adjustment of the sliding brackets 30, the width of the individual sliding brackets 30 may be made narrower, and the placement area may be increased by increasing the number of sliding brackets 30, so that in embodiments of the present invention, the sliding brackets 30 are provided to include at least two, such as two, three or more.

As shown in fig. 2, the sliding brackets 30 are sequentially arranged along the sliding direction of the sliding brackets 30 when in the unfolded position, and a linkage structure 35 is disposed between at least two adjacent sliding brackets 30. An example of the linkage 35 is shown in fig. 1.

Here, the linkage structure 35 means that when two sliding brackets 30 are connected through the linkage structure 35, one sliding bracket 30 can be driven to slide when the position of the other sliding bracket 30 is adjusted, so that at least two sliding brackets 30 can be moved at a time. When an object is placed on the sliding bracket 30, if the object rolls between the sliding bracket and the sliding bracket during movement, the object can be supported by the linkage structure 35 between the sliding bracket and the sliding bracket, so that the object above the sliding bracket is not easy to roll off during position adjustment.

In addition, the linkage 35 reduces the restriction on the relative positions of the two slide brackets 30 when not needed. Thus, the relative positions of the two slide brackets 30 can be changed at the time of storage, thereby improving the convenience of position adjustment.

The shelf assembly 100 of the embodiments of the present invention may be used in the field of kitchen appliances, for example, directly as a bowl shelf on a table top, or as an internal component of a dishwasher 1000, sterilizer, etc. The main shelf 10 is used for placing tableware such as dishes, and the sliding bracket 30 can horizontally place chopsticks, spoons and the like when in the unfolded position. The shelf assembly 100 may also be used as a bookshelf, the main shelf 10 is used for placing books, and the sliding bracket 30 can horizontally place a ruler pen or the like when in a unfolding position.

It will be appreciated that if a chopstick cage is provided in the main rack 10 to erect the chopsticks, during insertion of the chopsticks into the chopstick cage, the chopsticks may leak out of the hands and lodge in the main rack 10, requiring re-picking of the chopsticks for reinsertion. In comparison, after the sliding bracket 30 is arranged in the embodiment of the invention, people can horizontally put the chopsticks on the sliding bracket 30, so that the probability of leakage of the chopsticks from hands is reduced, and the putting mode is more in line with ergonomics and saves more labor.

In some embodiments, the side rail sections 20-2 of the slide rail 20 are fixedly connected to the main shelf 10, whereby the connection stability is high, and the support for the sliding bracket 30 can be better provided. The fixed connection mode between the slide rail 20 and the main shelf 10 is not limited, and can be welding connection, integral molding and the like. Of course, the embodiment of the present invention is not limited thereto, and a detachable connection such as a plug connection may be used between the side rail section 20-2 of the slide rail 20 and the main shelf 10.

In particular, the cross rail section 20-1 of the slide rail 20 may be a linear rail, for example, the cross rail section 20-1 may be disposed parallel to the bottom wall 12 of the main shelf 10. The cross rail section 20-1 of the slide rail 20 may be a wavy line shaped rail, or may be another linear rail, etc.

Likewise, the side rail sections 20-2 of the slide rail 20 may be linear rails, for example, the side rail sections 20-2 may be disposed perpendicular or oblique to the bottom wall 12 of the main shelf 10. The side rail sections 20-2 of the slide rail 20 may also be wavy line shaped rails, or other linear rails, etc.

In addition, the shape of the single slide rail 20 may be unlimited. For example, the rail 20 includes a cross rail section 20-1 and side rail sections 20-2 connected at both ends of the cross rail section 20-1, and the single rail 20 may be formed in an "n" shape. Alternatively, the track 20 may include a cross rail section 20-1 and side rail sections 20-2 attached to one end of the cross rail section 20-1, and the individual track 20 may be formed in an "L" shape. Alternatively, the track 20 includes two cross rail segments 20-1 and a side rail segment 20-2 connected between the two cross rail segments 20-1, and a single track 20 may form a "T" shape. In addition, more shapes can be designed when the shapes of the cross rail sections 20-1 and the side rail sections 20-2 are changed, for example, when the slide rail 20 includes a cross rail section 20-1 and side rail sections 20-2 connected to both ends of the cross rail section 20-1, the single slide rail 20 can be formed in an "M" shape by arranging the cross rail section 20-1 in a multi-fold line shape.

Further, as shown in fig. 1 and 3, the slide rail 20 further includes a transition section 20-3 connected between the cross rail section 20-1 and the side rail section 20-2, the transition section 20-3 being arcuate to enable smooth movement of the slide bracket 30 at the corner, facilitating switching of the slide bracket 30 between the cross rail section 20-1 and the side rail section 20-2.

In the embodiment of the present invention, the number of the sliding rails 20 is not limited, and may be one or more.

In some embodiments, as shown in fig. 1 and 2, the sliding rails 20 are two sliding rails 20 arranged at intervals, and two ends of the sliding bracket 30 are respectively connected with the two sliding rails 20 in a sliding manner. Thus, the two ends of the sliding bracket 30 are supported by the sliding rail 20, so that the sliding bracket 30 can be more stable when placed, and objects are not easy to incline and scatter when impacted, thus the requirement on assembly precision is low. And the connection structure between the sliding bracket 30 and the sliding rail 20 is relatively easy to set, so that the difficulty of structural design is reduced. In addition, the two slide rails 20 are arranged at intervals, and when the sliding bracket 30 returns to the storage position, the two slide rails 20 interfere with foreign objects less.

Specifically, as shown in fig. 1, the main shelf 10 includes a first side wall 111, a second side wall 112, and a third side wall 113 connected in sequence, the first side wall 111 and the third side wall 113 being disposed opposite to each other.

Wherein the side rail sections 20-2 of the two slide rails 20 are connected to the second side wall 112 and disposed adjacent to the first side wall 111 and the third side wall 113, respectively. Alternatively, the side rail sections 20-2 of the two slide rails 20 are connected to the first side wall 111, the third side wall 113, respectively, and disposed adjacent to the second side wall 112. Thus, when the slide bracket 30 is returned to the storage position, the two slide rails 20 interfere less with foreign objects. The slide carriage 30 may be configured to be longer and to more smoothly rest on the slide carriage 30 when the slide carriage 30 is returned to the deployed position.

In the embodiment of the present invention, the structure of the linkage structure 35 may be flexibly selected from various structural forms. For example, the linkage structure 35 includes at least one of a detachable structure, a magnetic attraction structure, a rope, and an elastic body.

Specifically, the linkage structure 35 may include a detachable structure, which may be a snap connection structure, a plug structure, or the like. The linkage structure 35 includes a first linkage part and a second linkage part, which are respectively disposed on the two sliding brackets 30 that are linked, and the first linkage part and the second linkage part are combined when linkage is required, and the first linkage part and the second linkage part are detached when linkage (e.g., storage) is not required.

The linkage structure 35 may include a magnetic attraction structure, for example, the linkage structure 35 includes a first linkage portion and a second linkage portion, which are respectively disposed on the two sliding brackets 30 that are linked. The first linkage part and the second linkage part can be magnetic attraction pieces respectively, and are magnets, or one of the magnets is a magnet, and the other is a common iron piece. When the first and second interlocking parts are closer, the suction force combines the first and second interlocking parts, so that the corresponding two sliding brackets 30 can slide simultaneously. When the two slide brackets 30 are pulled away by an external force, the suction force between the first and second interlocking parts is reduced to be ignored, and the two slide brackets 30 are in the mutually unlocked state.

The linkage structure 35 may include a rope or an elastic body, so that when the distance between the two sliding brackets 30 linked together exceeds a certain range, the two sliding brackets 30 can be driven to slide in the same direction by the rope or the elastic body. When the two sliding brackets 30 are required to be stored, the rope body or the elastic body can deform, so that the relative position of the two sliding brackets 30 is less constrained, and the relative position of the two sliding brackets 30 is allowed to be adjusted when the two sliding brackets are stored.

In some embodiments, as shown in fig. 3 and 4, when the slide bracket 30 is in the storage position, two slide brackets 30 linked are stacked in the thickness direction of the slide bracket 30. Thus, the thickness of the sliding bracket 30 is not large, the overall thickness of the sliding bracket is not increased too much after lamination, but the overall width of the sliding bracket can be greatly reduced, so that space is saved, and interference on objects on the main shelf 10 is reduced.

Specifically, as shown in fig. 1 and 4, the linkage structure 35 includes: a link hook 352 and a link ear 351. The link hooks 352 are provided on the side of one sliding bracket 30, and the link lugs 351 are provided on the side of the other sliding bracket 30.

When the sliding bracket 30 is positioned at the unfolding position, the linkage hook 352 is hung on the linkage lug 351; when the slide bracket 30 is in the storage position, the link hook 352 is disengaged from the link lug 351.

The linkage structure 35 with such a structure allows the two sliding brackets 30 to be very conveniently combined and separated, and is convenient to operate and time-saving. In addition, since the link hook 352 is hung on the link lug 351, the link hook 352 has a rotation angle range of a certain range with respect to the link lug 351. Therefore, when the two slide brackets 30 are combined and the angle between the two slide brackets 30 needs to be adjusted in sliding, the linkage structure 35 can be easily self-adjusted and adapted, and the clamping stagnation of the two slide brackets 30 in linkage is reduced.

Further, when the sliding brackets 30 are at the storage position, the two sliding brackets 30 which are linked are vertically arranged on the inner side and the outer side of the side wall 11 of the main shelf 10. The sliding bracket 30 occupies very little space when in the storage position, so that the inner space of the main shelf 10 is not occupied too much, and the width of the outer side of the main shelf 10 is not increased too much.

Here, as shown in fig. 3, the link hook 352 may be located at the bottom of one sliding bracket 30 in a vertical position, in which case the link hook 352 is located at the top of the other sliding bracket 30 in a vertical position. Alternatively, the linkage hook 352 and the linkage lug 351 may be interchanged, wherein the linkage hook 352 is located at the top of one vertically disposed sliding bracket 30, and the linkage hook 352 is located at the bottom of the other vertically disposed sliding bracket 30. It will be appreciated that the interlock hook 352 and the interlock ear 351 can be easily engaged and disengaged in sliding in both ways.

Further, as shown in fig. 2, when the link hook 352 is located at the bottom of a vertically arranged sliding bracket 30, in order to reduce interference of the side wall 11 of the main shelf 10, an avoidance groove 115 for avoiding the link hook 352 is formed on the side wall 11. This allows the link hooks 352 to move into the escape grooves 115 when the slide bracket 30 slides downward, and the link hooks 352 are not blocked by the side walls 11.

In some embodiments, as shown in fig. 1 and 2, the slide rail 20 includes at least one slide bar 21 extending in the sliding direction of the slide bracket 30, and the shelf assembly 100 satisfies at least one of:

case one: the sliding brackets 30 include a first bracket 31, and the first bracket 31 includes a sliding portion 310 that is limited between two adjacent sliding rods 21;

and a second case: the sliding bracket 30 comprises a second bracket 32, and the second bracket 32 comprises a slider 322 which is sleeved on the sliding rod 21.

In the first case, the sliding portion 310 of the first bracket 31 is sandwiched by the two slide bars 21, so that not only is the assembly easy, but also the shape of the slide bar 21 can define the movement locus of the sliding portion 310. Also, in the second case, the second bracket 32 is slid over the slide bar 21 by the slider 322, the assembly is easy, and the shape of the slide bar 21 can define the moving track of the sliding portion 310. And the sliding bracket 30 is smoother at the sliding switching position of the sliding rail 20.

In both cases, the sectional shape of the slide bar 21 is not required to be complicated, and the slide bar can be manufactured by adopting a conventional round bar, square bar and the like, and the cost is low. The slide bar 21 itself is an elongated bar, and the desired shape is obtained by bending. The angle of the slide bracket 30 at each position on the slide rail 20 can be accurately predicted by the shape of the slide bar 21. The slide rail 20 with the structure has the advantages of low cost, easy processing, small occupied volume, easy assembly and difficult clamping stagnation.

In particular, the sliding carriage 30 may comprise one or more first carriages 31, the sliding carriage 30 may also comprise one or more second carriages 32, or the sliding carriage 30 comprises at least one first carriage 31 and at least one second carriage 32. In the solution of the present application, the sliding brackets 30 are detachably mounted on the slide rail 20, so that the number of the sliding brackets 30 can be adjusted as required.

In the example shown in fig. 1 to 4, both end portions of the slide bracket 30 are connected to the slide rails 20 on both sides, respectively. In a still further example, as shown in fig. 5, two slide rails 20 may be disposed close to each other, and the intermediate position of the slide bracket 30 may be fitted to the two slide rails 20.

The slide bar 21 may be a narrow plate as shown in fig. 6, without limiting the use of a thin bar. The narrow plate can enlarge the contact surface between the slide rail 20 and the sliding bracket 30 or lengthen the contact line, which is beneficial to increasing the balance degree.

In addition, other shapes of the sliding rail 20 are also possible, for example, the section of the sliding rail 20 may be a groove shape as shown in fig. 7, and the sliding portion 310 of the sliding bracket 30 is located in the groove shape of the sliding rail 20. In some embodiments, the cross section of the sliding rail 20 may be designed into other shapes, and the sliding portion 310 is a sliding block that matches the cross section of the sliding rail 20.

In some embodiments, as shown in fig. 8 and 9, the sliding bracket 30 includes a first bracket 31, and the first bracket 31 includes at least one row of sliding portions 310, each row being provided with at least two sliding portions 310 and being spaced apart in a sliding direction of the first bracket 31.

Each sliding portion 310 includes: the connecting shaft 312 and the roller 313, the connecting shaft 312 is fixedly or detachably arranged on the first bracket 31, the roller 313 is sleeved on the connecting shaft 312, and as shown in fig. 1 and 2, the roller 313 (i.e. the sliding part 310 shown in fig. 1) is clamped between two adjacent slide bars 21. The connecting shaft 312 is used for connecting the roller 313, the roller 313 is in rolling fit on the sliding rail 20, so that the friction force between the sliding part 310 and the sliding rail 20 can be reduced, and the smoothness of the first bracket 31 during position adjustment can be improved.

Specifically, as shown in fig. 8, the first tray 31 includes a first tray 311, and the first tray 311 is used for placing chopsticks and spoons of equal length. The opposite ends of the first tray 311 are provided with sliding parts 310, so that both sides of the first tray 311 can slide along the sliding rail 20.

Specifically, a linking hook 352 is connected to one side of the first tray 311, and the linking hook 352 may be one or more than one.

Optionally, the first tray 311 is a grid-like structure, which reduces the weight of the first tray 311 and the overall shelf assembly 100. When the water-spraying type tableware is used for loading tableware, water can be conveniently sprayed.

Alternatively, at each end of the first tray 311, the connection shaft 312 is provided in two or more. Further alternatively, the first tray 311 may have at least two connecting shafts 312 connected to each of the opposite short sides, and two connecting shafts 312 are disposed at both ends of the short sides, so that the sliding stability of the first tray 311 may be improved.

In order to make the roller 313 not easy to slip off the connecting shaft 312, a limiting structure 33 is disposed at one end of the connecting shaft 312 away from the first tray 311. The structure of the limiting structure 33 is not limited, and the roller 313 can be prevented from slipping.

Alternatively, as shown in fig. 9, the limiting structure 33 includes at least two cantilevers 331, and a limiting wedge 332 is provided at an end of each cantilever 331. A gap is provided between the cantilevers 331, and the small end of the limiting wedge 332 is far away from the cantilevers 331 while the large end is connected with the cantilevers 331. Thus, when the roller 313 is sleeved on the limiting structure 33, the roller 313 is guided by the shape of the limiting wedge 332 to press the cantilever 331, so that all the cantilevers 331 are contracted, and the roller 313 is sleeved on the cantilever 331. When the shape guide without the limit wedge 332 is not provided, the plurality of cantilevers 331 are restored to open, making the roller 313 difficult to separate from the limit structure 33. Such a limit structure 33 not only realizes the anti-drop function, but also facilitates the means of connecting the roller 313 with the connecting shaft 312. In addition, when an external force presses the limiting wedge 332 to shrink all the cantilevers 331 again, the roller 313 can be detached.

In some embodiments, the roller 313 and the connecting shaft 312 may be detachably connected by other structures. Such as a threaded connection, a snap-fit connection, etc.

In some embodiments, as shown in fig. 10 and 11, the sliding bracket 30 includes a second bracket 32, and the second bracket 32 includes at least one row of sliders 322, each row being provided with at least two sliders 322 and being spaced apart in a sliding direction of the second bracket 32, thereby improving sliding stability of the second bracket 32. Specifically, the slider 322 is fixedly or detachably provided on the second bracket 32. The connection form of the slider 322 can be flexibly selected according to the need.

The sliding bracket 30 includes at least one second bracket 32, the second bracket 32 includes a second tray 321 and at least two sliders 322, and the at least two sliders 322 are respectively connected at opposite ends of the second tray 321.

Specifically, the slider 322 may be provided in two or more to be disposed at opposite sides of the second tray 321, respectively. The sliding buckle 322 may also be provided with at least two on opposite sides of the second tray 321, so as to improve the sliding stability of the second tray 321. For example, two, three, four, etc. may be provided, respectively. Preferably, the sliders 322 are respectively provided at two opposite sides of the second tray 321.

Optionally, the second tray 321 is a grid-like structure, which reduces the weight of the second tray 321 and the overall shelf assembly 100.

Specifically, one side of the second tray 321 is connected with a linkage ear 351, and the linkage ear 351 may be one or more than one.

Further, as shown in fig. 10, in order to facilitate the processing and manufacturing of the second bracket 32, the second tray 321 and the slider 322 may be processed separately, and then assembled together, so that the slider 322 can rotate relative to the second tray 321. Thus, when the second bracket 32 slides along the sliding rail 20, the adjustable slider 322 can be utilized to adjust when the rotation angle or the rotation directions of the two ends are not parallel, so as to reduce the jamming probability.

Specifically, the slide fastener 322 is provided with a limit structure 33, the frame of the second tray 321 is provided with a through hole, the limit structure 33 can be inserted into the through hole, the limit wedge 332 is utilized to realize anti-drop, the slide fastener 322 is not influenced to rotate relative to the second tray 321, and the sliding adjustability of the second bracket 32 is improved.

Alternatively, both the first bracket 31 and the second bracket 32 are manufactured by injection molding. On the first bracket 31, the first tray 311, the connection shaft 312 and the carried limit structure 33 are integrally injection-molded, and then the roller 313 is mounted on the connection shaft 312. On the second bracket 32, the second tray 321 is independently injection molded, the slide buckle 322 and the carried limit structure 33 are integrally injection molded, and then the slide buckle 322 is inserted into the limit structure 33 on the second tray 321. So designed, each slide bracket 30 is relatively inexpensive to manufacture and can be made to accommodate sliding on the slide rail 20.

Specifically, when the opposite ends of the sliding bracket 30 are respectively connected to the two sliding rails 20, the distance between the two sliding rails 20 is greater than the length of the bearing portion (e.g., the first tray 311 and the second tray 321) of the sliding bracket 30. More specifically, the length of the bearing portion of the sliding bracket 30 is greater than the length of the elongated object to be supported. For example, in one embodiment where the shelving assembly 100 is designed to hold cutlery, the sliding tray 30 is designed to hold at least chopsticks, and the length of chopsticks that a person uses daily is about 22-24 cm, the length of the holding portion of the sliding tray 30 can be set to 30 cm, and the spacing between the two rails 20 can be designed to 34 cm.

In some embodiments, as shown in fig. 1 to 4, the sliding rods 21 are two and are respectively an inner sliding rod 21a and an outer sliding rod 21b, the lower end of the inner sliding rod 21a is located inside the side wall 11 of the main shelf 10, and the lower end of the outer sliding rod 21b is located outside the side wall 11 of the main shelf 10. The sliding bracket 30 is located at least partially inside the side wall 11 of the main shelf 10 or outside the side wall 11 of the main shelf 10 when in the storage position.

By the arrangement, at least two sliding brackets 30 can be overlapped on the side wall 11 of the main shelf 10, and at least one sliding bracket 30 can be overlapped on the inner side and the outer side respectively, as shown in fig. 1, the sliding brackets 30 occupy little space when in the storage position, so that the inner space of the main shelf 10 is not occupied too much, and the increase of the width of the outer side of the main shelf 10 is not excessively large.

Here, the inner slide bar 21a and the outer slide bar 21b each have a portion extending laterally above or below the main shelf 10, and each portion belongs to the lateral rail 20-1. The inner slide bar 21a and the outer slide bar 21b each have a portion extending to the bottom wall 12 or the side wall 11 of the main shelf 10 to bring the slide bracket 30 to the storage position, which portions belong to the side rail section 20-2.

Specifically, the inner slide bar 21a and the outer slide bar 21b are disposed in parallel at least in part of the cross rail section 20-1. Alternatively, the portions of the inner slide bar 21a and the outer slide bar 21b at the side rail sections 20-2 may or may not be disposed in parallel.

Alternatively, when the slide bracket 30 includes the roller 313 sandwiched between the inner slide bar 21a and the outer slide bar 21b, the gap between the inner slide bar 21a and the outer slide bar 21b is at least larger than the contact circle diameter of the roller 313. Here, the contact circle of the roller 313 refers to a circle line or a cylindrical surface in contact with at least one slide bar 21 in the outer circumferential surface of the roller 313.

Due to the supporting strength of the roller 313 and the smoothness of the roller 313, the contact circle diameter of the roller 313 is at least more than 2mm, and the unilateral gap between the roller 313 and the sliding rail 20 is at least more than 0.5mm.

Specifically, as shown in fig. 12, the slide rail 20 further includes a hanging rod 22, and the hanging rod 22 is connected to the lower end of at least one of the inner slide rod 21a and the outer slide rod 21b, and the hanging rod 22 is clamped on the side wall 11 of the main shelf 10. The hanging rod 22 is utilized, the assembly process of the sliding rail 20 and the main shelf 10 is simpler, the contact line between the hanging rod 22 and the side wall 11 of the main shelf 10 is long, the hanging rod 22 supports the whole sliding rail 20, the bending resistance of the sliding rail 20 is enhanced, and the supporting capacity of the sliding rail 20 is improved.

Here, the hanger bar 22 may have an inverted v shape, and the upper end of the hanger bar 22 spans the side wall 11 of the main shelf 10, and the two struts 221 of the hanger bar 22 are sandwiched between the inner and outer sides of the side wall 11. In some embodiments, a clip may be provided to secure one or both of the struts 221 to the side wall 11 of the main shelf 10 to provide a secure connection.

Other configurations of hanger 22 are possible. In some specific examples, as shown in fig. 13, one of the two support rods 221 of the hanger bar 22 has a lower end connected to a lower end of the outer slide bar 21b, and the other support rod 221 may be attached to the side wall 11 of the main shelf 10. Alternatively, the struts 221 located inside the side wall 11 of the main shelf 10 are designed in a wavy line shape, and the struts 221 repeatedly pass through the side wall 11 of the main shelf 10 a plurality of times. In other specific examples, as shown in fig. 14, one of the two support rods 221 of the hanger bar 22 has a lower end connected to a lower end of the outer slide bar 21b, and the other support rod 221 may be attached to the side wall 11 of the main shelf 10.

In some embodiments, each sliding rail 20 is formed by bending a thin rod, and after the thin rod is bent in different directions, different shapes can be obtained. The thin rod may be an iron rod, a steel rod, or the like, and the thin rod material is not limited herein.

Specifically, the main shelf 10 includes a bottom wall 12 and at least one side wall 11, and the bottom wall 12 and the side wall 11 may be formed by bending a thin rod. The main shelf 10 can be made of one or more thin rods, and is welded and fixed at the joint after being bent.

In some embodiments, as shown in FIG. 12, one end of the cross rail segment 20-1 is connected to the side rail segment 20-2 and the other end is a cantilevered end. The inner slide bar 21a and the outer slide bar 21b are connected at the cantilever ends, and the inner slide bar 21a, the outer slide bar 21b and the hanging bar 22 are integrated rods formed by bending.

The inner slide rod 21a and the outer slide rod 21b are connected at the cantilever ends, so that the sliding bracket 30 is not easy to be separated from the cantilever ends when sliding to the transverse rail section 20-1, and can be used as a positioning structure of the sliding bracket 30 in the unfolding position.

The inner slide bar 21a and the outer slide bar 21b are integrally formed with the hanging bar 22, and the hanging bar 22 is hung on the main shelf 10 to fixedly support the whole slide rail 20. Wherein the inner slide bar 21a and the outer slide bar 21b are no longer in close connection at this end of the side rail section 20-2, e.g. the lower end of the inner slide bar 21a is not connected to the hanger bar 22, from where the sliding bracket 30, such as the second bracket 32, can be fitted with the inner slide bar 21a and then can slide along the inner slide bar 21 a. Alternatively, the lower end of the inner slide bar 21a is provided with a hook 21c3, and the sliding bracket 30 is stopped by the hook 21c3 when sliding to the lower end of the inner slide bar 21 a. Of course, the inner slide 21a may be formed in other shapes in the present application, for example, the lower end of the inner slide 21a may be punched to form a cylinder after the second bracket 32 is attached to the inner slide 21 a.

Alternatively, as shown in fig. 3 and 12, when the slide bracket 30 includes the first bracket 31, the sliding portion 310 is sandwiched between the inner slide bar 21a and the outer slide bar 21b, and the surfaces of the two slide bars 21 are sliding surfaces. A mounting empty space 23 is formed between the inner slide bar 21a and the outer slide bar 21b above the side wall 11 of the main shelf 10. When the sliding portion 310 slides to the installation empty region 23, the projection of the installation empty region 23 on the sliding surface, the projection of the sliding portion 310 on the sliding surface is completely turned.

That is, at a position above the side wall 11 of the main shelf 10 where the gap between the inner slide bar 21a and the outer slide bar 21b is relatively large, which is referred to as the installation empty area 23, when the first bracket 31 slides thereto, the sliding portion 310 can be freely withdrawn through the installation empty area 23, so that the sliding portion 310 is released from the restraint of the inner slide bar 21a and the outer slide bar 21b, and the first bracket 31 is detached from the slide rail 20. When the installation is required, the sliding portion 310 is inserted into the installation space 23 so that the sliding portion 310 is inserted between the inner slide bar 21a and the outer slide bar 21b and can slide along the slide rail 20.

Wherein, because the projection of the installation empty area 23 on the sliding surface and the projection of the sliding part 310 on the sliding surface are completely turned over, the sliding part 310 is not blocked by the sliding rod 21 at all, so that the sliding part 310 can be easily assembled and disassembled.

Specifically, as shown in FIG. 12, the outer slide bar 21b is integrally a vertical bar 21c1 at the side rail section 20-2. The inner slide bar 21a includes three sections in the side rail section 20-2, an upper and a lower section being a vertical bar 21c1 and a middle section being an inclined bar 21c2. The inclined rod 21c2 is located just above the hanger 22, and the triangular area enclosed by the middle inclined rod 21c2 of the inner slide rod 21a, the top end of the hanger 22, and the outer slide rod 21b is the installation empty area 23. More specifically, the triangular region is formed on the sliding surface, the sliding portion 310 has a shape of a revolution, and the diameter of the inscribed circle of the triangular region is equal to or larger than the maximum diameter of the sliding portion 310.

Of course, the solution of the present application is not limited thereto, for example, since the lower end of the inner slide bar 21a is a free end, when the sliding portion 310 needs to be detached, the inner slide bar 21a may be pulled, so that the gap between the inner slide bar 21a and the outer slide bar 21b becomes larger, and the obstruction of the sliding portion 310 by the slide bar 21 is reduced.

In some embodiments, as shown in fig. 1-4, the sliding bracket 30 includes a first bracket 31 and a second bracket 32, the sliding portion 310 is sandwiched between an inner sliding bar 21a and an outer sliding bar 21b, the slider 322 is sleeved on the inner sliding bar 21a or the outer sliding bar 21b, and the lower end of the outer sliding bar 21b is connected to the hanging bar 22. The first bracket 31 is located inside the side wall 11 of the main shelf 10 in the storage position, the second bracket 32 is located outside the side wall 11 of the main shelf 10 in the storage position, and the sliding portion 310 is sandwiched between the hanger bar 22 and the outer slide bar 21 b. The shelf assembly 100 can simultaneously support the first bracket 31 and the second bracket 32, so that the two sliding brackets 30 can be received on both inner and outer sides of the side wall 11 of the main shelf 10 without excessively increasing the width of the side wall 11 of the main shelf 10. When the sliding bracket 30 is unfolded, the first bracket 31 and the second bracket 32 can be spliced together, so that the combined width of the sliding bracket 30 is larger, and more objects can be placed.

In some embodiments, the linkage structure 35 includes at least one of a detachable structure and a magnetically attractable structure. The two sliding brackets 30 correspondingly linked with each other form a sliding track, and the distance between the two sliding tracks is greater than the distance between the two sliding tracks when the sliding track is in the unfolding position when the sliding track is in the storage position, so that the linkage structure 35 is unlocked when the sliding track distance is increased, and the linkage structure 35 is combined when the sliding track distance is reduced. Therefore, the linkage structure can be semi-automatically completed in the unlocking and combining process.

Taking the sliding bracket 30 comprising the first bracket 31 and the second bracket 32, the sliding portion 310 is clamped between the inner sliding rod 21a and the outer sliding rod 21b, the sliding buckle 322 is sleeved on the inner sliding rod 21a or the outer sliding rod 21b, and the lower end of the outer sliding rod 21b is connected with the hanging rod 22 as an example. The first bracket 31 is located inside the side wall 11 of the main shelf 10 in the storage position, the second bracket 32 is located outside the side wall 11 of the main shelf 10 in the storage position, and the sliding portion 310 is sandwiched between the hanger bar 22 and the outer slide bar 21 b.

The inner slide bar 21a forms a slide path of the second bracket 32, and the outer slide bar 21b forms a slide path of the first bracket 31. On the transverse rail section 20-1, the distance between the inner slide bar 21a and the outer slide bar 21b is small. On the side rail section 20-2, the distance between the inner slide bar 21a and the outer slide bar 21b becomes larger from smaller. The vertical rod 21c1 of the inner slide rod 21a corresponds to the distance change of the two sliding tracks.

When the first bracket 31 and the second bracket 32 move from top to bottom and the link structure 35 slides to the vertical rod 21c1, the distance between the first bracket 31 and the second bracket 32 becomes larger, so that the link lug 351 and the link hook 352 are far away from each other to unlock. When the second bracket 32 in the storage position is slid upward and to the vertical rod 21c1, the first bracket 31 does not need to be slid at this time, and the link hook 352 gradually approaches the link lug 351, so that the link hook 352 can be inserted into the link lug 351 in the approaching process.

When the linkage structure 35 adopts a magnetic attraction structure, the unlocking and matching processes of the linkage structure 35 can be automatically completed.

A dishwasher 1000 according to an embodiment of the second aspect of the present invention is described below with reference to the accompanying drawings.

For ease of comparison, a conventional chopstick cage mounted on the main shelf 10 and the slide rail 20 with the slide bracket 30 of the above described embodiment are shown in fig. 15. The chopsticks cage and the chopsticks and spoons vertically arranged therein are shown in solid lines, the length of the chopsticks resulting in a higher space above the main shelf 10, which results in a space above the vertically arranged dish being left unused. The slide rail 20 and chopsticks and spoons transversely arranged on the slide rail are shown by dotted lines, and the height space occupied by the chopsticks is greatly reduced due to transverse arrangement of the chopsticks. And under the sliding bracket 30, the original chopsticks cage can be removed and more dishes can be placed.

According to the dish washer 1000 of the embodiment of the application, the utilization rate of the cavity in the dish washer 1000 is improved by adopting the rack assembly 100, and more tableware can be washed at one time.

Specifically, each rack may be slidably disposed within the case 200, thereby facilitating loading and unloading of dishes.

In some embodiments, the dishwasher 1000 further includes an upper rack 300 drawably disposed within the housing 200, the cross rail section 20-1 of the slide rail 20 being located below the upper rack 300 and above the main rack 20. Therefore, the gap between the upper shelf and the lower shelf can be fully utilized, and the upper part of the main shelf 20 can be convenient for a user to put long and thin chopsticks, spoons and other tableware.

Further, in order not to affect the normal operation of the shower arm 400 above the sliding bracket 30, the distance between the highest point of the sliding bracket 30 where the dishes are placed and the lowest point of the shower arm 400 is greater than 5mm.
