Description

Technical Field

[0001] This invention relates to the field of dishwasher accessories technology, specifically a foldable dish rack assembly for a dishwasher. Background Technology

[0002] As a convenient kitchen appliance, the dishwasher's internal dish rack assembly is the core component that holds the tableware, directly affecting the stability of the tableware placement, the cleaning coverage, and the space utilization. Currently, common dish rack assemblies are generally divided into upper and lower layers to increase the holding capacity.

[0003] However, most existing dishwashers have fixed racks that cannot be folded, which presents the following technical drawbacks: First, fixed racks cannot flexibly adjust their internal space according to the size of the tableware. When placing large pots, plates, or small tableware, the upper rack is prone to interference. This is especially true for small dishwashers, where fixed racks significantly limit the types and quantities of tableware they can hold. Second, when the dishwasher is not in use, the racks cannot be folded for storage, taking up a large amount of storage space. This makes it inconvenient for users to clean the inside of the dishwasher and also makes it difficult to disassemble and store the racks themselves.

[0004] Therefore, it is necessary to provide a new foldable dishwasher basket assembly to solve the above-mentioned technical problems. Summary of the Invention

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] First embodiment: Please refer to the following: Figures 1-12The dishwasher foldable basket assembly includes two basket mechanisms arranged one above the other. Each basket mechanism includes two side plates 1. Positioning guide rails 2 are bolted to the sides of the two side plates 1 that are close to each other. A first-shaped guardrail 3 and a second-shaped guardrail 4 are provided between the two positioning guide rails 2. The first-shaped guardrail 3 is fixedly connected to the two positioning guide rails 2 by multiple positioning folding rods. Multiple first connecting vertical rods 5 are fixedly installed inside the first-shaped guardrail 3. Hollow columns 6 are fixedly installed on the side of each of the multiple first connecting vertical rods 5 near the second-shaped guardrail 4. Multiple second connecting vertical rods 7 are fixedly installed inside the second-shaped guardrail 4. Each side of the first-shaped fence 3 is fixedly equipped with a connector 8. Each connector 8 has a sliding rod 9 fixedly installed on the side near the hollow column 6. One end of each sliding rod 9 is inserted into a corresponding hollow column 6 and slidably connected to it. By pulling the second-shaped fence 4, the basket mechanism can be stretched or folded. Two positioning columns 10 are fixedly installed on the sides of the first-shaped fence 3 and the second-shaped fence 4 that are close to each other. Multiple positioning sliding arms 11 are slidably installed on the two positioning guide rails 2. Each positioning sliding arm 11 has a movable column 1001 fixedly installed on one side, and each movable column 1001 is located at a position corresponding to one of the two positioning columns. Between positions 10 and 1001, and in the folded / retracted state, the positioning column 10 and the movable column 1001 are in contact, and two adjacent movable columns 1001 are in contact. A connecting beam 1007 is fixedly installed between each of the corresponding two positioning columns 10 and the corresponding two movable columns 1001. The connecting beam 1007 and the hollow column 6 are vertically distributed, with the hollow column 6 located below the connecting beam 1007. The two are in contact, thus forming a bottom mesh structure to ensure that the kitchen utensils to be washed can be stably placed inside the dish rack mechanism. Multiple movable columns 1001 are located between corresponding two positioning columns 10, and a first movable column is opened on the side of each corresponding two positioning columns 10 that is close to each other. The groove 1002, the two sides of the multiple movable columns 1001 are provided with second movable grooves 1003, the multiple first movable grooves 1002 are adapted to the corresponding second movable grooves 1003. The adaptation method specifically means that the first movable groove 1002 on the positioning column 10 can form a corresponding cooperation with the second movable groove 1003 on the adjacent movable column 1001, thereby forming a space for the hinge arm 1006 to move. At the same time, two adjacent second movable grooves 1003 are adapted to each other. Two first sliders 1004 are slidably installed in each of the multiple first movable grooves 1002, and two second sliders 1005 are slidably installed in each of the multiple second movable grooves 1003.Multiple first movable slots 1002 form first movable spaces with corresponding second movable slots 1003, and each pair of adjacent second movable slots 1003 forms a second movable space. Each of the multiple first and second movable spaces is provided with two centrally hinged hinge arms 1006. In the first movable space, the four ends of the two hinge arms 1006 are respectively hinged to two first sliders 1004 and two second sliders 1005. In the second movable space, the four ends of the two hinge arms 1006 are respectively hinged to four second sliders 1005. Utilizing the sliding function of the first sliders 1004 and second sliders 1005, and the hinged nature of the hinge arms 1006, the movable column 1001 can be stretched or contracted.

[0020] In this embodiment, in order to allow the dish rack mechanism to be pulled out of the dishwasher for easy placement of kitchen utensils to be washed, two pull-out guide grooves 12 are provided on the two side plates 1 that are far apart from each other. Pull-out guide rails 1201 are slidably installed in each of the four pull-out guide grooves 12, and mounting holes are provided on the pull-out guide grooves 12 for connection with the dishwasher inner tub. Two abutment blocks 1202 are fixedly installed on the two side plates 1 that are far apart from each other, and limit blocks 1203 are fixedly installed on each of the four pull-out guide rails 1201. The four abutment blocks 1202 are adapted to the four limit blocks 1203 respectively. By using the cooperation of the abutment blocks 1202 and the limit blocks 1203, the maximum formation is limited, so that the dish rack mechanism will not be pulled out of the dishwasher, ensuring the stability of use.

[0021] In this embodiment, in order to lock the second mouth-shaped fence 4 after folding or unfolding, two locking grooves 13 are opened at the top of the second mouth-shaped fence 4. Two connecting posts 1301 are fixedly installed at the top of the two positioning guide rails 2 by bolts. A fixing strip 1302 is provided above the two positioning guide rails 2, and a weight-reducing opening is opened on the fixing strip 1302 to achieve a lightweight design of the fixing strip 1302. The corresponding two connecting posts 1301 are fixedly connected to the corresponding fixing strip 1302. Two telescopic rods 1303 are slidably installed on the two fixing strips 1302. The same C-shaped frame strip 1304 is fixedly installed at the top of the four telescopic rods 1303. The C-shaped frame strip 1304 is located near the side of the side plate 1, and the C-shaped design does not hinder the user from placing kitchen utensils in the dish rack mechanism. A first wedge-shaped insert 1305 is fixedly installed at the bottom of the four telescopic rods 1303, near the first mouth-shaped fence. The bottoms of the two first wedge-shaped inserts 1305 of the rail 3 are inserted into the corresponding slots 13. Each of the four telescopic rods 1303 is fitted with a first tension spring 1306. The tops of the four first tension springs 1306 are fixedly connected to the corresponding fixing strips 1302, and the bottoms of the four first tension springs 1306 are fixedly connected to the corresponding first wedge-shaped inserts 1305. Furthermore, the cross-sectional shape of the first opening-shaped fence 3 and the second opening-shaped fence 4 is circular. The sides of the two corresponding first wedge-shaped inserts 1305 that are close to each other are set as inclined sliding surfaces. The inclined sliding surfaces are adapted to the circular cross-section of the second opening-shaped fence 4. Through the cooperation of the circular cross-section and the inclined sliding surfaces, and the elastic assistance of the first tension springs 1306, when the two are in contact, the first wedge-shaped inserts 1305 can automatically extend and retract. When they are vertically aligned with the slots 13, under the action of the first tension springs 1306, the first wedge-shaped inserts 1305 are automatically inserted into the slots 13, thereby improving the ease of operation.

[0022] In this embodiment The two dish rack mechanisms, arranged one above the other, can be pulled out independently without interfering with each other. The upper rack can be used alone, the lower rack alone, or both racks can be used simultaneously, depending on the needs of loading tableware. Furthermore, the pull-out guide rail 1201 is connected to the dishwasher inner tub by screws. The side plate 1 can drive the entire dish rack mechanism to slide back and forth along the pull-out guide rail 1201 to realize the function of pulling out and placing tableware. At the same time, the abutment block 1202 and the limit block 1203 are adapted to limit the pull-out stroke of the dish rack mechanism to prevent the dish rack from falling off due to excessive pulling and to ensure safety during use.

[0023] Initially, both basket mechanisms are folded and retracted. When it is necessary to unfold the basket mechanisms, one of them is operated first. During operation, the corresponding U-shaped frame 1304 is lifted upwards, causing the corresponding first wedge-shaped insert 1305 to rise, thereby bringing out the first wedge-shaped insert 1305 that was originally inserted into the locking groove 13. At this time, the first tension spring 1306 is in a deeply compressed state. Then, the corresponding second-shaped fence 4 is moved away from the first-shaped fence 3 along the corresponding positioning guide rail 2. When the locking groove 13 is misaligned with the previously engaged first wedge-shaped insert 1305, the U-shaped frame 1304 is released, and the compressed first tension spring 1306 releases its elasticity, causing the four first wedge-shaped inserts 1305 to return to their original positions. At the same time, the slide rod 9 slides synchronously along the hollow column 6, playing a guiding and limiting role to prevent the second-shaped fence 4 from deviating. The movement ensures a smooth and stable extension process. During the pulling of the second mouth-shaped fence 4, the extension and retraction of the hinged arms 1006 in the first movable groove 1002 and the second movable groove 1003 gradually unfolds the multiple movable columns 1001. When the second mouth-shaped fence 4 contacts another first wedge-shaped insert 1305, its circular cross-section matches the inclined sliding surface of the first wedge-shaped insert 1305, causing the first wedge-shaped insert 1305 to automatically rise. When the first wedge-shaped insert 1305 aligns with the locking groove 13, the first tension spring 1306 automatically brings the first wedge-shaped insert 1305 into the locking groove 13, thus completing the unfolding of one of the bowl basket mechanisms. The distance between two adjacent movable columns 1001 is also stretched to the maximum, thereby adjusting the load-bearing space inside the bowl basket mechanism to accommodate tableware of different sizes.

[0024] Then, depending on the number of dish racks needed, if two dish racks are used at the same time, the other dish rack can be unfolded in the same way as described above. If only one dish rack is needed, there is no need to unfold the other dish rack. After that, open the dishwasher lid, pull out the dish rack, put the items to be washed into it, and then close the lid to start the washing process.

[0025] When the dishwasher is idle and the dish rack assembly is not needed, the dish rack mechanism can be completely folded to reduce space occupation and facilitate cleaning of the inside of the dishwasher and storage of the dish rack itself. During operation, first lift the C-shaped frame bar 1304 upwards to bring the first wedge-shaped insert 1305 out of the locking groove 13, and then push the second opening fence 4 directly toward the first opening fence 3 until the positioning post 10 contacts the movable post 1001, and two adjacent movable posts 1001 contact each other, and the corresponding first wedge-shaped insert 1305 is also inserted into the locking groove 13, thereby completing the folding and retraction of the dish rack mechanism.

[0026] Compared with related technologies, the foldable dish rack assembly for dishwashers provided by this invention has the following advantages: I. The present invention can unfold the bowl basket mechanism by the relative sliding of the first mouth-shaped fence 3 and the second mouth-shaped fence 4, combined with the guiding and limiting of the sliding rod 9 and the hollow column 6, and the locking of the locking groove 13 and the first wedge-shaped insert 1305, so as to adapt to large pots, plates and small tableware, and improve the diversity of tableware carrying capacity. Second, in this invention, when the dishwasher is idle or the dish rack mechanism is disassembled for storage, the positioning column 10 and the movable column 1001 are brought into contact by pushing the second-shaped fence 4, as well as two adjacent movable columns 1001 are brought into contact, thereby realizing the horizontal folding of a single dish rack mechanism. After folding, the space occupied is greatly reduced, which facilitates the cleaning of the dishwasher inner drum and the storage of the dish rack itself. Third, the present invention provides stable sliding support for the extension and retraction of the basket through the positioning guide rail 2, and the vertical fit between the connecting beam 1007 and the hollow column 6 enhances the structural firmness; and the contact block 1202 and the limiting block 1203 cooperate to limit the extension stroke and prevent the basket from falling off. The overall structure is stable and safe to use.

[0027] Second embodiment: Based on the foldable dishwasher basket assembly provided in the first embodiment of this application, the second embodiment of this application proposes another foldable dishwasher basket assembly. The second embodiment is merely a further embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0028] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Please refer to the following: Figures 13-18In the second embodiment of the dishwasher foldable dish rack assembly proposed in this invention: two vertical adjustment guide rails 14 are fixedly installed on the side of the two upper side plates 1 that are close to each other, forming four vertical adjustment guide rails 14. Adjustment blocks 15 are slidably installed on each of the four vertical adjustment guide rails 14. By adjusting the height of the adjustment blocks 15, the distance between the upper and lower dish rack mechanisms can be adjusted, accommodating larger kitchen utensils. The four adjustment blocks 15 are grouped in pairs, and two positioning guide rails 2 are fixedly connected to the adjustment blocks 15 in the two groups respectively. By adjusting the height of the adjustment blocks 15, the positioning guide rails 2 and the... The height adjustment of the entire bowl basket mechanism allows for adjustment of the distance between the upper and lower bowl basket mechanisms. A countersunk hole 16 is provided on one side of each of the two adjusting blocks 15 near the second-shaped fence 4. Positioning plates 17 are fixedly installed on the adjacent sides of the two upper side plates 1. A connecting rod 1701 is slidably mounted on each of the two positioning plates 17. The connecting rod 1701 has a quadrilateral cross-section to ensure linear sliding and prevent rotation. A U-shaped insert rod 1702 is fixedly installed at one end of each connecting rod 1701 near the vertical adjustment guide rail 14. The lower ends of the two U-shaped insert rods 1702... The two adjusting blocks 15 are respectively inserted into the countersunk holes 16, locking the basket mechanism in this position. Furthermore, a second tension spring 1703 is fitted onto each of the two connecting rods 1701. One end of each second tension spring 1703 is fixedly connected to one of the two positioning plates 17, and the other end is fixedly connected to one of the two U-shaped inserts 1702. In addition, a second wedge-shaped insert 1704 is fixedly installed at the end of each connecting rod 1701 away from the vertical adjusting guide rail 14. A common horizontal platform 18 is fixedly installed on one side of each of the two upper side plates 1, with locking bolts threaded onto it. 1801, A connecting crossbar 1802 is rotatably mounted on the bottom end of the locking bolt 1801. Two wedge-shaped abutment arms 1803 are fixedly mounted on the bottom of the connecting crossbar 1802. The bottom inclined edges of the two wedge-shaped abutment arms 1803 abut against the top inclined edges of the two second wedge-shaped inserts 1704 respectively. Thus, the abutment between the two can make the C-shaped insert 1702 stably inserted into the recessed countersunk hole 16. At the same time, in order to ensure the stability of the lifting and lowering of the connecting crossbar 1802 and the unidirectionality of the direction, two guide posts are fixed on the top of the connecting crossbar 1802. The top ends of the two guide posts pass through the cross platform 18 and are slidably connected to it.

[0030] In this embodiment, in order to prevent the adjusting block 15 from detaching from the vertical adjusting guide rail 14, four support platforms are fixedly installed on the side of the two upper side plates 1 that are close to each other. The top and bottom ends of the four vertical adjusting guide rails 14 are fixedly connected to the corresponding support platforms, and the four adjusting blocks 15 are respectively attached to the four support platforms located below.

[0031] In this embodiment In the initial state, the second spring 1703 is in a compressed state.

[0032] To accommodate larger kitchen utensils (such as large pots and pans whose handles require more space to be placed), the height of the upper basket mechanism needs to be adjusted, thereby adjusting the distance between the upper and lower basket mechanisms.

[0033] During operation, first rotate the locking bolt 1801, causing the connecting crossbar 1802 to move upward. The wedge-shaped contact arm 1803 then moves upward, releasing its contact with the second wedge-shaped insert 1704. At this point, the second tension spring 1703 resets, causing the connecting rod 1701 to move. The U-shaped insert 1702 disengages from the recessed countersunk hole 16, releasing the positioning of the adjusting block 15, allowing adjustment of the upper basket height. After adjustment, the recessed countersunk hole 16 is horizontally aligned with the upper end of the U-shaped insert 1702. Then, rotate the locking bolt 1801 in the opposite direction. 801, the connecting bar 1802 moves downward, the wedge-shaped contact arm 1803 presses the second wedge-shaped insert 1704, pushes the connecting rod 1701 to move, and the upper end of the U-shaped insert 1702 is inserted into the recessed hole 16. At the same time, the second tension spring 1703 is compressed to lock the adjusting block 15 in place, ensuring the upper rack mechanism is height stable. At this time, the distance between the upper and lower rack mechanisms is maximized.
