Description

Technical Field

[0001] This utility model relates to the technical field of washing machines for cleaning tableware and / or fruits and vegetables, and specifically to a shelf assembly for a washing machine and a washing machine. Background Technology

[0002] Washing machines, such as dishwashers, typically have a dish rack inside the cabinet for placing tableware, fruits, and vegetables, which are then washed. For example, the Chinese utility model patent application CN202321310996.7 (publication number CN219846492U) discloses a shelf for a dishwasher. The shelf includes a shelf with drainage holes; a first positioning row disposed on the shelf, the first positioning row including a plurality of vertically extending positioning posts arranged in a row at intervals, with a positioning gap formed between two adjacent positioning posts for positioning the head of a spoon. The shelf also includes a frame extending upward from the periphery of the shelf.

[0003] The shelf structure of this patent is a whole and fixed relative to the frame. The tableware is laid directly on the shelf. The frame can limit the tableware in the circumferential direction. However, some tableware is prone to upward displacement when rinsed by water, which not only affects the cleaning effect but also makes it easy to break. This patent does not have a structure that can limit the tableware from the top. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a rack assembly for a washing machine that can perform multi-directional positioning of tableware as needed, in light of the current state of the technology.

[0005] The second technical problem to be solved by this utility model is to provide a cleaning machine that uses the above-mentioned shelf assembly, in view of the current state of the prior art.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a shelf assembly for a cleaning machine, comprising a frame, characterized in that the frame includes a first hollow region and a second hollow region arranged adjacent to each other in the left-right direction, the shelf assembly further includes a shelf and a basket with an open top, the basket is fixedly disposed in the first hollow region, the shelf is provided with a first mounting part, the side wall of the frame is provided with a second mounting part on which the first mounting part can be rotatably mounted, the rotation axis between the first mounting part and the second mounting part extends in the front-back direction, the second mounting part is adjacent to the second hollow region, the shelf can be in a first position or a second position, in the state where the shelf is in the first position, the shelf covers the top of the basket; in the state where the shelf is in the second position, the shelf is located in the second hollow region.

[0007] To ensure the shelf can be positioned relative to the frame in either the first or second position, the shelf is provided with a first positioning part, which is spaced apart from the first mounting part in the left-right direction. The side wall of the frame is provided with a second and a third positioning part. The second mounting part is located between the second and third positioning parts in the left-right direction. The second positioning part corresponds to a first hollow area, and the third positioning part corresponds to a second hollow area. When the shelf is in the first position, the first and second positioning parts are detachably bound together; when the shelf is in the second position, the first and third positioning parts are detachably bound together. Thus, the shelf is positioned not only through the cooperation of the first and second mounting parts, but also through the cooperation of the first positioning part with either the second or third positioning part.

[0008] Preferably, the shelf is provided with a first mounting part and a first positioning part on both its front and rear side walls, and correspondingly, the frame is provided with a second mounting part, a second positioning part, and a third positioning part on both its front and rear side walls. This provides multi-point positioning between the frame and the shelf, resulting in good positioning performance.

[0009] The first, second, and third positioning parts can have various structural forms. For example, all three positioning parts can be magnets; alternatively, the first positioning part can be a protrusion, and the second and third positioning parts can be slots; or the first positioning part can be a slot, and the second and third positioning parts can be protrusions. The combination of slots and protrusions not only facilitates the switching of the frame position but also has a simple structure and low cost.

[0010] To limit the placement of tableware within the area enclosed by the shelf and basket when the shelf is in the first position, a first limiting row is provided on the bottom wall of the basket. The first limiting row includes multiple first limiting rods spaced apart in a front-to-back direction. The wall facing upwards when the shelf is in the second position is referred to as the first wall. A second limiting row is provided on the first wall of the shelf. The second limiting row includes multiple second limiting rods spaced apart in a front-to-back direction. When the shelf is in the first position, the second limiting rods are inserted between two adjacent first limiting rods, i.e., the first and second limiting rods are staggered, thereby achieving the purpose of positioning tableware (such as a steamer cloth) and expanding the usable space of the shelf assembly.

[0011] In order to support a certain amount of tableware and allow for washing when the shelf is in the first position, preferably, the downward-facing wall surface of the shelf in the second position is referred to as the second wall surface. The second wall surface of the shelf is provided with a third limiting row, which includes multiple third limiting rods arranged at intervals along the front-back direction. The third limiting rods serve to limit the tableware.

[0012] The first positioning part and the second mounting part can have various structural forms. Preferably, the first mounting part is a rotating shaft extending in the front-back direction, and the second mounting part is an inverted U-shaped through hole, including a first vertical hole, a second vertical hole extending vertically, and a transverse hole connecting the top of the first vertical hole and the second vertical hole. The first vertical hole penetrates the bottom edge of the frame, and the second vertical hole does not penetrate the bottom edge of the frame. The first mounting part slides through the first vertical hole and the transverse hole in sequence and is rotatably placed at the bottom end of the second vertical hole.

[0013] To improve the connection strength between the basket and the frame, the basket and the frame are integrally formed.

[0014] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a cleaning machine, characterized in that: it includes a box with an open top or side and the aforementioned shelf assembly, wherein the shelf assembly can be disposed in the box.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets a basket and a shelf in the frame. The shelf can rotate to a first position and a second position. When the shelf is in the first position, the shelf covers the top of the basket. At this time, the shelf and the basket form a relatively closed space, in which items that are easily moved upward by the water flow, such as cloths and small plates, can be placed, and the tableware can be positioned in multiple directions. When the shelf is in the second position, the shelf is located in the second hollow area. At this time, items can be placed in both the shelf and the basket, and a large number of items can be placed. The shelf can be placed in either the first or second position according to whether the tableware being washed is easily moved upward by the water flow. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-5 As shown, the cleaning machine of this preferred embodiment includes a housing (not shown) and a shelf assembly. The top or side of the housing is open, and the shelf assembly can be installed inside the housing.

[0023] The shelving assembly includes a frame 1, a shelf 2, and a basket 3, with drainage holes provided on both the shelf 2 and the basket 3.

[0024] The frame 1 includes a first hollow area 11 and a second hollow area 12 arranged adjacent to each other in the left and right direction. The basket 3 is fixedly installed in the first hollow area 11. In this embodiment, the top of the basket 3 is open. The basket 3 has a bottom plate and a peripheral wall formed around the bottom plate. The basket 3 and the frame 1 are integrally formed. The shelf 2 is plate-shaped as a whole.

[0025] The shelf 2 is provided with a first mounting part 21, and the side wall of the frame 1 is provided with a second mounting part 13 on which the first mounting part 21 can be rotatably mounted. The axis of rotation between the first mounting part 21 and the second mounting part 13 extends in the front-rear direction. The second mounting part 13 is adjacent to the second hollow area 12. The shelf 2 can be in either the first position or the second position. Figure 5 As shown, with shelf 2 in the first position, shelf 2 covers the top of basket 3; as Figure 1 As shown, when the shelf 2 is in the second position, the shelf 2 is located in the second hollow region 12.

[0026] In this embodiment, the first mounting part 21 is a rotating shaft extending in the front-back direction, and the second mounting part 13 is an inverted U-shaped through hole, including a first vertical hole 131 extending vertically, a second vertical hole 132, and a transverse hole 133 connecting the top of the first vertical hole 131 and the second vertical hole 132. The first vertical hole 131 penetrates the bottom edge of the frame 1, and the second vertical hole 132 does not penetrate the bottom edge of the frame 1. The first mounting part 21 slides through the first vertical hole 131 and the transverse hole 133 in sequence and is rotatably placed at the bottom end of the second vertical hole 132.

[0027] To ensure that the shelf 2 can be positioned relative to the frame 1 in either the first or second position, the shelf 2 is provided with a first positioning part 22, which is spaced apart from the first mounting part 21 in the left-right direction. The side wall of the frame 1 is provided with a second positioning part 14 and a third positioning part 15. A second mounting part 13 is located between the second positioning part 14 and the third positioning part 15 in the left-right direction. The second positioning part 14 corresponds to the first hollow area 11, and the third positioning part 15 corresponds to the second hollow area 12. When the shelf 2 is in the first position, the first positioning part 22 and the second positioning part 14 are detachably bound together. When the shelf 2 is in the second position, the first positioning part 22 and the third positioning part 15 are detachably bound together. Thus, the shelf 2 is positioned not only through the cooperation of the first mounting part 21 and the second mounting part 13, but also through the cooperation of the first positioning part 22 with either the second positioning part 14 or the third positioning part 15.

[0028] In this embodiment, the first positioning part 22 is a slot, and the second positioning part 14 and the third positioning part 15 are both protrusions. Alternatively, the first positioning part 22 can be a protrusion, and the second positioning part 14 and the third positioning part 15 can be slots. To facilitate the disengagement of the protrusion from the slot, a hollow hole 16 is provided on the side wall of the frame 1. A rib 17 extending in the left-right direction is provided in the hollow hole 16. The rib 17 can generate a certain displacement in the front-back direction, and the protrusion is provided on the rib 17.

[0029] In addition, the shelf 2 is provided with a first mounting part 21 and a first positioning part 22 on both the front and rear side walls. Correspondingly, the frame 1 is provided with a second mounting part 13, a second positioning part 14 and a third positioning part 15 on both the front and rear side walls. This provides multi-point positioning between the frame 1 and the shelf 2, resulting in a good positioning effect.

[0030] The bottom wall of the basket 3 is provided with a first limiting row 31, which includes a plurality of first limiting rods 311 arranged at intervals along the front-back direction. The wall surface facing upward when the shelf 2 is in the second position is called the first wall surface. The first wall surface of the shelf 2 is provided with a second limiting row 23, which includes a plurality of second limiting rods 231 arranged at intervals along the front-back direction. When the shelf 2 is in the first position, the second limiting rods 231 are inserted between two adjacent first limiting rods 311, that is, the first limiting rods 311 and the second limiting rods 231 are staggered. When the shelf 2 is in the first position, the area enclosed by the shelf 2 and the basket 3 limits the tableware (such as a steamer cloth).

[0031] In order to support certain tableware and allow for washing when the shelf 2 is in the first position, the downward-facing wall surface of the shelf 2 in the second position is referred to as the second wall surface. The second wall surface of the shelf 2 is provided with a third limiting row 24, which includes multiple third limiting rods 241 arranged sequentially and spaced apart in the front-back direction. The third limiting rods 241 serve to limit the tableware.
