Technical Field

[0001] This invention relates to the field of household appliances, and more particularly to shelf structures and dishwashers. Background Technology

[0002] In household appliances such as dishwashers and sterilizers, shelves are usually needed to place tableware. For example, dishwashers are usually equipped with two or three shelves to place various tableware or other items that need to be washed.

[0003] Currently, with the increasing market penetration of dishwashers, users are demanding higher cleaning efficiency, greater ease of use, and superior cleaning results. For example, in home settings, users frequently need to clean food residue from the bottom of the dishwasher's inner drum. Currently, dishwasher racks are typically fixed, requiring users to pull the rack out or push it into the dishwasher cavity to place or remove dishes, making the cleaning process cumbersome.

[0004] Therefore, how to optimize shelf functionality through structural design to improve user convenience has become an urgent problem to be solved in the current dishwasher technology field. Summary of the Invention

[0068] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0069] In common household appliances such as dishwashers and sterilizers, shelves are core load-bearing components, primarily used for categorizing and placing various tableware, kitchen utensils, and items awaiting washing. Dishwashers typically feature double or triple-layer fixed shelves inside the cavity to accommodate the placement and washing needs of tableware of different sizes. However, as the market penetration of dishwashers continues to increase, consumers' comprehensive requirements for cleaning efficiency, ease of operation, hygiene, and ease of daily maintenance are constantly rising. The limitations of traditional fixed shelf structures are becoming increasingly apparent, making it difficult to meet the refined usage needs of today's users.

[0070] In related technologies, dishwashers typically use a fixed, integral shelf structure. The shelf is fixed to the cavity and cannot be folded, opened, or adjusted. During daily use, users can only remove or place dishes and clean food residue by pulling or pushing the entire shelf in, a cumbersome and laborious process that significantly reduces the ease of use. Furthermore, the fixed lower shelf obstructs the water spray inside the dishwasher, hindering full water coverage and resulting in uneven cleaning of upper dishes, poor cleaning performance, and reduced overall cleaning efficiency.

[0071] In addition, food residue that falls off during the dishwashing process is very easy to accumulate and remain in the gaps of the fixed shelves and the bearing surfaces. Not only is it difficult to clean manually and the cleaning is not thorough, but the inside of the dishwasher is a humid and sealed environment after it is working. The accumulated residue is prone to the growth of bacteria, mold and other microorganisms, which can cause secondary pollution to the dishes washed later, seriously affecting the hygiene of the dishes and posing certain safety hazards.

[0072] In summary, existing dishwasher rack structures suffer from numerous technical drawbacks, including cumbersome cleaning operations, water flow obstruction affecting cleaning performance, and food residue accumulation leading to secondary pollution. Therefore, there is an urgent need to optimize the design of the racks to improve their overall structure, balancing the stability of the dishes under load, effective cleaning, and ease of daily maintenance, thereby addressing the many shortcomings of current technology.

[0073] This application provides a shelf structure in which a second side frame and a first side frame are disposed opposite each other along a first direction; along the first direction, a first intermediate component is located between the first and second side frames; and the first intermediate component includes multiple main supports, which are spaced apart along the first direction, and each main support extends along a second direction, which intersects the first direction; the first side frame and its adjacent main support, two adjacent main supports, and the second side frame and its adjacent main support are all rotatably connected to achieve relative folding or unfolding between them. This invention improves user convenience.

[0074] The shelf structure and dishwasher provided in the embodiments of the present invention are described below with reference to the accompanying drawings.

[0075] refer to Figure 1 and Figure 2 As shown, this application provides a shelf structure 100. Specifically, in conjunction with... Figure 3 and Figure 4 As shown, the shelving structure 100 may include a first side frame 110 and a second side frame 120, wherein the second side frame 120 and the first side frame 110 may be arranged opposite to each other along a first direction L1.

[0076] In this embodiment of the application, the shelf structure 100 may further include a first intermediate component 130, wherein the first intermediate component 130 may be located between the first side frame 110 and the second side frame 120 along the first direction L1.

[0077] Specifically, refer to Figure 5 and Figure 6 As shown in the embodiment of this application, the first intermediate component 130 may include a plurality of main supports 131, wherein the plurality of main supports 131 may be distributed at intervals along the first direction L1, and each main support 131 may be extended along the second direction L2.

[0078] In this embodiment of the application, the second direction L2 may intersect with the first direction L1.

[0079] In this embodiment, the first side frame 110 and the main support 131 adjacent to it, the two adjacent main supports 131, and the second side frame 120 and the main support 131 adjacent to it can be rotatably connected to achieve relative folding or unfolding between them.

[0080] The basic load-bearing structure, consisting of the first side frame 110, the second side frame 120, and multiple sets of spaced main supports 131, can stably support various types of tableware, meeting the basic daily tableware placement needs of the dishwasher. Meanwhile, the connecting points employ a rotating connection method, enabling the overall shelf structure 100 to fold and unfold. This eliminates the drawback of traditional fixed shelf structures 100, which cannot move. Without needing to pull out the entire shelf, the bottom of the dishwasher's inner drum and shelf gaps can be quickly exposed by folding the shelf, greatly simplifying residue cleaning and improving user convenience.

[0081] Moreover, the folding structure reduces the obstruction of water flow by the shelves, effectively optimizing the water circulation path inside the cavity and laying a structural foundation for improving the cleaning effect of tableware.

[0082] In this embodiment of the application, the shelf structure 100 may further include a second intermediate component 140. The second intermediate component 140 may be located between the first side frame 110 and the second side frame 120 along the first direction L1.

[0083] Specifically, refer to Figures 5 to 7 As shown in the embodiment of this application, the second intermediate component 140 may include a plurality of auxiliary supports 141, wherein the plurality of auxiliary supports 141 may be distributed at intervals along the first direction L1, and each auxiliary support 141 may be extended along the second direction L2.

[0084] In this embodiment of the application, an auxiliary support 141 can be provided between the first side frame 110 and the main support 131 adjacent thereto, between two adjacent main supports 131, and between the second side frame 120 and the main support 131 adjacent thereto. Moreover, the first side frame 110, the main support 131 and the second side frame 120 can be rotatably connected to the corresponding auxiliary support 141.

[0085] In this way, the auxiliary support 141 and the main support 131 are arranged in a one-to-one correspondence and matching manner, which further densifies the support structure of the shelf structure 100, and can adapt to the placement needs of small and fine tableware, prevent small tableware from falling during the washing process, and reduce the problem of residue falling and accumulating.

[0086] Meanwhile, the auxiliary support 141 is rotatably connected to the side frame and the main support 131, and can complete the folding and unfolding actions synchronously with the main support 131. While improving the load-bearing stability of the shelf structure 100 and the adaptability of tableware, it will not affect the overall flexible folding function of the shelf structure 100, continuously ensuring the convenience of cleaning the inner pot, and further reducing the risk of bacterial growth and secondary pollution caused by residue accumulation.

[0087] Continue to refer to Figure 7As shown, each auxiliary bracket 141 may also be provided with multiple partitions 1411.

[0088] By setting multiple partitions 1411 on each auxiliary support 141, the partitions 1411 can be used to separate and limit the tableware placed on the shelf, forming an independent limiting constraint. Specifically, it can divide and position various tableware such as bowls, plates, and dishes, effectively solving the problems of tableware stacking, sliding, colliding, and tipping over during dishwasher cleaning.

[0089] In addition, the isolation and limiting function of the partition 1411 ensures that each piece of tableware is placed independently, preventing tableware from sticking together and blocking cleaning dead corners. This allows the spray water to fully rinse the surface of the tableware, significantly improving the uniformity and cleanliness of the tableware cleaning and increasing the overall cleaning efficiency of the machine.

[0090] like Figure 8 As shown in the embodiments of this application, the shelf structure 100 may further include: a plurality of hinge assemblies 150. For example... Figure 1 and Figure 2 As shown, a hinge assembly 150 is provided between the first side frame 110 and the main support 131 adjacent to it, between two adjacent main supports 131, and between the second side frame 120 and the main support 131 adjacent to it.

[0091] By setting hinge components 150 at each rotation connection position, a dedicated connection structure is provided for the folding and unfolding of the shelf structure 100, replacing the ordinary rotation connection method. This effectively improves the structural strength and rotational stability of each component connection position, avoids problems such as loosening, offset, and jamming after long-term repeated folding and unfolding operations, and greatly improves the service life and stability of the shelf structure 100.

[0092] Meanwhile, the hinge assembly 150 ensures uniform rotation amplitude at all positions, making the folding and unfolding process of the shelf structure 100 smoother, further optimizing the user's operating experience, and ensuring convenient cleaning and stable water flow.

[0093] like Figure 8 and Figure 9 As shown in the embodiments of this application, each hinge assembly 150 may include a first hinge 151 and a second hinge 152, wherein the first hinge 151 and the second hinge 152 are respectively rotatably connected to the corresponding auxiliary bracket 141.

[0094] The hinge assembly 150 is further subdivided into a first hinge 151 and a second hinge 152 that cooperate with each other, and the two sets of hinges are respectively rotatably connected to the corresponding auxiliary bracket 141 to form a double hinge linkage structure. Compared with the single hinge structure, it can distribute the rotational force, reduce the load pressure of a single hinge, and effectively avoid hinge deformation and damage.

[0095] Meanwhile, the linkage between the double hinges and the auxiliary support 141 enables the synchronous rotation of the main support 131, the auxiliary support 141, and the side frame, making the overall folding and unfolding of the shelf structure 100 more coordinated, the structural movement more stable, and preventing local structural jamming or misalignment, thus ensuring the shelf structure 100 is flexibly adjustable and easy to clean.

[0096] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, in the hinge assembly 150 between the first side frame 110 and the main support 131 adjacent thereto, the first end of the first hinge 151 is rotatably connected to the first side frame 110, the second end of the first hinge 151 and the first end of the second hinge 152 and the corresponding auxiliary support 141 are rotatably connected, and the second end of the second hinge 152 is rotatably connected to the main support 131 adjacent thereto.

[0097] In the hinge assembly 150 between two adjacent main supports 131, the first end of the first hinge 151 is rotatably connected to one of the main supports 131, the second end of the first hinge 151 and the first end of the second hinge 152 are rotatably connected to the corresponding auxiliary support 141, and the second end of the second hinge 152 is rotatably connected to the other main support 131.

[0098] In the hinge assembly 150 between the second side frame 120 and the main support 131 adjacent thereto, the first end of the first hinge 151 is rotatably connected to the main support 131 adjacent thereto, the second end of the first hinge 151 and the first end of the second hinge 152 and the corresponding auxiliary support 141 are rotatably connected, and the second end of the second hinge 152 is rotatably connected to the second side frame 120.

[0099] By further defining the specific connection and cooperation relationship of the hinge components 150 at different positions, and setting up double hinge connection structures for three different connection scenarios, namely the first side frame 110 and the main support 131, the adjacent main support 131, and the second side frame 120 and the main support 131, the standardization and adaptation design of the rotation structure of each area of ​​the shelf structure 100 is realized, so that the folding action of the left and right sides and the middle area of ​​the shelf structure 100 is uniform and synchronous, avoiding the problems of incomplete folding and uneven stress on the structure.

[0100] Meanwhile, the precise hinge connection enhances the stability and consistency of the overall structure, ensuring that the shelf structure is flat when fully unfolded and fits tightly when folded. This not only guarantees the stability of tableware placement but also maximizes the exposed inner space, improves the efficiency of residue cleaning, and prevents secondary pollution caused by residue accumulation.

[0101] In the embodiments of this application, reference is made to Figure 1As shown, the shelf structure 100 may further include a connecting assembly 160. The connecting assembly 160 may include at least one connecting rocker arm 161, one end of which may be rotatably connected to the first side frame 110, and the other end of which may be rotatably connected to the second side frame 120.

[0102] In this way, by utilizing the rotational connection characteristics between the two ends of the connecting rocker arm 161 and the two side frames, the dispersed side frames, main support 131, and auxiliary support 141 are linked into a whole structure, which effectively improves the integrity and coordinated movement capability of the entire shelf structure 100 and avoids misalignment, displacement, or loosening of the components during folding and unfolding.

[0103] Meanwhile, the connecting rocker arm 161 can limit and adjust the spacing between the two side frames, making the unfolded state of the shelf more regular and stable, further optimizing the tableware placement effect, and the overall linkage structure makes the folding operation easier and smoother, continuously improving the user's operational convenience.

[0104] It is understood that in some embodiments, there may be multiple connecting rockers 161. Multiple connecting rockers 161 may be arranged side by side.

[0105] Multiple parallel connecting rockers 161 can simultaneously pull and limit the first side frame 110, the second side frame 120, and the intermediate support components, making the overall force of the shelf structure 100 more balanced during folding, unfolding, and sliding. This effectively suppresses deformation, warping, or loose swaying in the middle and local areas of the shelf structure 100, and greatly improves the synchronicity and stability of the overall movement of the shelf structure 100.

[0106] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the connecting rocker arm 161 may include multiple sub-connecting rods 1611. A sub-connecting rod 1611 may be provided between the first side frame 110 and the auxiliary support 141 adjacent to it, between the auxiliary support 141 and the main support 131, and between the second side frame 120 and the auxiliary support 141 adjacent to it. Moreover, the first side frame 110, the main support 131, and the second side frame 120 may be rotatably connected to the corresponding sub-connecting rod 1611.

[0107] The connecting rocker arm 161 is subdivided into multiple sets of sub-connecting rods 1611, and the sub-connecting rods 1611 are arranged to match the connection nodes of the side frame, auxiliary support 141, and main support 131. This realizes the independent linkage constraint of each rotation connection node of the shelf structure 100, so that every rotation movement of the main support 131, auxiliary support 141, and side frame can be precisely synchronized, and completely solves the problems of motion lag and structural loosening that occur in the linkage of multiple components.

[0108] In addition, the subdivided sub-connecting rod 1611 structure can evenly distribute the overall force, greatly improving the structural stability and durability of the shelf structure 100 for long-term use, while not affecting the folding flexibility of the shelf structure 100, and continuously ensuring cleaning effect and ease of cleaning.

[0109] Combination Figure 10 As shown in the embodiment of this application, the shelf structure 100 may further include fixed columns 170, wherein each end of each main support 131 and each end of each auxiliary support 141 is fixedly connected to a fixed column 170. A rotating shaft 171 may be provided on the fixed column 170, and the sub-connecting rods 1611 on both sides of each fixed column 170 may be rotatably connected to the rotating shaft 171.

[0110] Fixed columns 170 and rotating shafts 171 are added to both ends of each main support 131 and auxiliary support 141. The fixed columns 170 reinforce the ends of the supports, improving their structural strength and preventing deformation and cracking after long-term support of tableware. At the same time, the rotating shafts 171 on the fixed columns 170 enable the rotational connection of the sub-connecting rods 1611, providing a precise and stable rotation fulcrum for each linkage structure. This effectively reduces frictional resistance during rotation, making the folding and unfolding of the shelf structure 100 smoother.

[0111] In some embodiments, see Figure 10 As shown, each pivot 171 can also be provided with a limiting element 172 at the end opposite to the fixed column 170. The limiting element 172 can prevent the sub-connecting rod 1611 from falling off or shifting, further improving the reliability of the overall structure and ensuring the long-term stable operation of the shelf structure 100.

[0112] like Figure 11 As shown in the embodiment of this application, the shelf structure 100 may further include a limiting rod 180. One end of the limiting rod 180 may be fixed to one of the first side frame 110 and the second side frame 120, and the other end of the limiting rod 180 may be engaged with the other of the first side frame 110 and the second side frame 120, for fixing the relative position of the first side frame 110 and the second side frame 120 after the shelf structure 100 is folded.

[0113] For example, Figure 11In the middle, the limiting rod 180 may include a limiting rod body 181, a fixing buckle 182 and a snap fastener 183. One end of the limiting rod body 181 is connected to the fixing buckle 182, which is fixed to the second side frame 120. The other end of the limiting rod body 181 is connected to the snap fastener 183, which is snapped onto the first side frame 110.

[0114] In this way, the relative positions of the first side frame 110 and the second side frame 120 can be locked after the shelf structure 100 is fully folded, which effectively prevents the folded shelf structure 100 from popping open or loosening on its own during the handling, storage or use of the dishwasher, improves the structural stability in the folded state, reduces the space occupied, and makes it convenient for users to store.

[0115] Meanwhile, the limit locking structure is simple to operate and reliable in fixing, and will not affect the normal folding and unfolding operation of the shelf structure 100, further improving the product's functionality and enhancing the overall user experience.

[0116] In one possible implementation, a fixing part 121 may also be provided on the first side frame 110 and one of the second side frames 120 (see reference). Figure 1 (As shown). One end of the limiting rod 180 can be fixed to the fixing part 121. This ensures the stability of the limiting rod 180 and avoids interference between the placement of the limiting rod 180 and the structure of the first side frame 110 or the second side frame 120 itself.

[0117] In addition, in this embodiment of the application, the shelf structure 100 may also include a plurality of rollers 190.

[0118] It is understood that in some embodiments, at least the first side frame 110 and the second side frame 120 may be connected to rollers 190.

[0119] The rollers 190 on the side frame can directly cooperate with the dishwasher cavity slide rails, greatly reducing the frictional resistance during the pulling and pushing of the shelves, making the operation of the shelves in and out of the cavity easier and smoother, avoiding the problems of traditional shelves being stuck, difficult to push and pull, and offsetting and wearing, further improving the convenience of users to pick up and put down tableware.

[0120] Furthermore, in this embodiment of the application, rollers 190 may also be connected to the first intermediate component 130 and / or the second intermediate component 140.

[0121] By adding rollers 190 to the first intermediate component 130 and / or the second intermediate component 140, auxiliary support and guiding limit can be formed for the middle area of ​​the shelf structure 100, which can effectively improve the situation of the middle of the shelf structure 100 sinking under force and shifting when large-sized, heavy-duty tableware is placed, and improve the overall stability of the shelf structure 100 and the structural load-bearing stability.

[0122] In addition, the multi-point roller 190 structure can effectively reduce the hard friction wear between the shelf and the cavity and slide rail, extending the service life of the shelf and dishwasher cavity accessories. Moreover, the roller 190 does not affect the normal folding and unfolding function of the shelf structure 100, and can work together with the folding structure to further optimize the overall feel and durability of the machine while ensuring convenient cleaning, high-quality cleaning effect and eliminating secondary pollution, thus comprehensively improving the performance of the product.

[0123] refer to Figure 12 As shown, this application also provides a dishwasher 200, which may include the shelf structure 100 described above.

[0124] In some embodiments, the dishwasher 200 may include a housing 210 and the shelf structure 100 described above, the shelf structure 100 being disposed within the housing 210.

[0125] The other structural features of the dishwasher 200 are similar to those of existing structures and will not be described in detail here.

[0126] The dishwasher 200 provided by this invention is equipped with the aforementioned foldable shelf structure 100. Relying on this foldable and adjustable shelf structure 100, it completely solves the industry pain points of traditional dishwashers 200, such as cumbersome cleaning of fixed shelves, severe water flow obstruction, and secondary pollution caused by bacterial growth from food residue accumulation. The dishwasher 200 can quickly clean food residue from the inner drum through the flexible folding of the shelf, resulting in smoother water circulation within the cavity. This comprehensively improves the evenness and cleaning effect of the dishes, while significantly reducing the difficulty of cleaning and maintenance. It enhances the overall ease of use, hygiene, and product quality, thereby strengthening the market competitiveness of the dishwasher 200.
