Description

Technical Field

[0001] This invention belongs to the field of dishwasher technology, specifically, it relates to a detachable double-layer shelf. Background Technology

[0002] A dishwasher is a device that automatically cleans tableware, bringing great convenience to people's daily lives. One type of dishwasher uses water to wash dishes; these typically have a spray system that uses water jets to clean the dishes placed inside. Another type uses steam to clean dishes; these have a built-in steam generator. Regardless of the type, the number of dishes placed inside the dishwasher determines its efficiency. Dishwashers usually have racks where users place the dishes to be washed, and the dishwasher automatically washes them. The more dishes on the racks, the more dishes the dishwasher can wash simultaneously.

[0003] An existing Chinese patent discloses a dishwasher shelf, including a shelf side wall and a bottom support. A bracket is provided on the shelf side wall, and the bracket is connected to the shelf side wall through a mounting part. The bracket and the mounting part have two connection states: a sliding connection state in the vertical direction of the mounting part and a rotational connection state in the mounting part about the axial direction. The mounting part is provided with a positioning structure to keep the bracket at a certain angle with the shelf side wall. When the bracket rotates about the axial direction of the mounting part to form another certain angle with the shelf side wall, the bracket slides in the vertical direction of the mounting part.

[0004] Existing dishwashers have limited capacity for both the types and quantities of tableware that can be placed inside.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a detachable double-layer shelf that can hold more different kinds of tableware.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A detachable double-layer shelf includes a lower shelf and an upper shelf, wherein at least one support is provided on the lower shelf, and the upper shelf is detachably installed on the top of the support.

[0009] Preferably, a first support member is provided at the center of the first side of the lower shelf. The first support member has a first strut and a second strut extending vertically upward, and the top ends of the first strut and the second strut are connected by a first connecting rod.

[0010] Preferably, the first connecting rod has a first locking position and a second locking position at both ends, which are U-shaped and open towards the outside of the lower shelf.

[0011] Preferably, a second support member is provided on the second side of the lower shelf. The second support member includes a third support rod and a fourth support rod extending vertically upward. The upper half of the third support rod extends toward the side of the fourth support rod, and the top of the third support rod and the top of the fourth support rod are connected by a second connecting rod.

[0012] Preferably, the second side of the lower shelf is adjacent to the first side of the lower shelf, and the second support is located at the end of the second side of the lower shelf away from the first side of the lower shelf.

[0013] Preferably, a fifth and a sixth support rod extend horizontally from the top of the third and fourth support rods toward the interior of the lower shelf, and the free ends of the fifth and sixth support rods are connected by a second connecting rod.

[0014] Preferably, a third support member is provided inside the lower shelf near the center of the upper shelf. The third support member includes a seventh support rod and an eighth support rod extending vertically upward, and the top ends of the seventh support rod and the eighth support rod are connected by a third connecting rod.

[0015] Preferably, the third connecting rod has a downwardly curved recess.

[0016] Preferably, the upper shelf includes a first support and a second support that are parallel to each other and form an "L" shape. The first end of the first support and the first end of the second support are connected by a third support, and the second end of the first support and the second end of the second support are connected by a fourth support.

[0017] Preferably, the first end of the first bracket and the first end of the second bracket are provided with a third and a fourth slot in a semi-circular shape with the opening facing downwards. The third slot is placed above the first slot, the fourth slot is placed above the second slot, and the third bracket is placed below the first and second slots.

[0018] Preferably, the upper shelf rests on the curved part of the third connecting rod via a fourth connecting rod fixed near the corner of the second support and having an upwardly curved protrusion, and the upper shelf rests on the fifth and sixth support rods via the fourth support.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] 1. By adding an upper shelf above the lower shelf, this invention allows for the placement of more different types of tableware inside the dishwasher when multiple different sizes of tableware are placed on the dishwasher shelves at the same time. This increases the number of tableware that can be placed inside the dishwasher and improves the utilization rate of the dishwasher's internal space.

[0021] 2. By installing the upper shelf in a detachable manner, the present invention allows users to remove or install the upper shelf at any time, making it convenient for users to place tableware on the lower shelf or take tableware out from the lower shelf.

[0022] 3. The present invention provides a semi-circular locking position on the upper shelf and a corresponding "U"-shaped locking position on the first support member, so that the upper shelf can be locked onto the first support member, which facilitates the installation or removal of the upper shelf and provides a good support effect.

[0023] 4. This invention, by setting up a second and a third support member, allows the upper shelf to rest on the second and third support members. The third support member distributes the pressure exerted on the upper shelf by the tableware, preventing the upper shelf from deforming due to excessive pressure. At the same time, the third support member supports the upper shelf, making it more stable.

[0024] 5. The present invention provides a downwardly curved recess on the third connecting rod of the third support member, and a fourth connecting rod fixed to the bottom of the upper shelf has an upwardly curved protrusion. The protrusion of the fourth connecting rod rests on the recess of the third connecting rod, thus preventing the upper shelf from shaking after tableware is placed on it.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] like Figures 1 to 7As shown, this invention introduces a detachable double-layer shelf, including a lower shelf 1 and an upper shelf 2. The lower shelf 1 has at least one support member, and the upper shelf 2 is detachably mounted on top of the support member. By adding an upper shelf 2 above the lower shelf 1, this invention allows for the placement of multiple different sized tableware items on the upper shelf 2 while the lower shelf 1 is simultaneously occupied. This increases the number of tableware items that can be placed inside the dishwasher, avoiding wasted internal space due to varying tableware sizes and improving the utilization rate of the dishwasher's internal space.

[0040] Example 1

[0041] like Figure 1 and Figure 3 As shown, in this embodiment, the lower shelf 1 is divided into six areas for placing tableware of different sizes, including a large plate area 11, a small plate area 12, a large bowl area 13, a small bowl area 14, a water cup area 15, and a chopsticks holder area 16. The tableware placed in the large plate area 11 and the large bowl area 13 is relatively large, while the tableware placed in the small bowl area 14 and the water cup area 15 is relatively small. Therefore, after placing tableware on the lower shelf 1, there is still some empty space above the small bowl area 14 and the water cup area 15, which can be used to place more tableware.

[0042] In this embodiment, because the tableware placed in the large plate area 11 and the large bowl area 13 is relatively large and tall, while the tableware placed in the small bowl area 14 and the water cup area 15 is relatively short, the internal space of the dishwasher is wasted, resulting in fewer tableware placed in the dishwasher. In this embodiment, an upper shelf 2 is added above the lower shelf 1. The upper shelf 2 is located above the small bowl area 14 and the water cup area 15, and the tableware placed in the small bowl area 14 and the water cup area 15 is located between the lower shelf 1 and the upper shelf 2. At the same time, the upper shelf 2 does not affect the placement of tableware in the large plate area 11, the small plate area 12, the large bowl area 13, and the chopsticks holder area 16.

[0043] The upper shelf 2 can continue to hold dishes, increasing the number of dishes that can be placed inside the dishwasher and improving the utilization of the dishwasher's internal space.

[0044] Example 2

[0045] like Figures 1 to 3 As shown, in this embodiment, the small bowl area 14 and the water cup area 15, which are used to place smaller tableware, form an area similar to an "L". In order to continue to place tableware above the small bowl area 14 and the water cup area 15, the upper shelf 2 is also set to the same shape.

[0046] In this embodiment, the support includes a first support 3 and a second support 4, and the upper shelf 2 includes a first bracket 21 and a second bracket 22 that are parallel to each other and form an "L" shape. The first end of the first bracket 21 and the first end of the second bracket 22 are connected by a third bracket 23 that is snapped into the first support 3, and the second end of the first bracket 21 and the second end of the second bracket 22 are connected by a fourth bracket 24, which rests on the second support 4.

[0047] The upper shelf 2 is equipped with multiple support ribs, including those of a certain length, for placing smaller bowls, plates, and other small tableware. Simultaneously, shorter support ribs are provided between the first support 21 and the second support 22 for placing slender tableware such as chopsticks and cutlery. This fully utilizes the space above the upper shelf 2, allowing for the placement of more tableware.

[0048] Example 3

[0049] like Figure 1 and Figure 2 As shown, in this embodiment, the first bracket 21 has an upwardly protruding, semi-circular third locking position 211 at its first end. The third locking position 211 is connected to the first end of the third bracket 23 and is locked onto the first support member 3. The second bracket 22 has an upwardly protruding, semi-circular fourth locking position 221 at its first end. The fourth locking position 221 is connected to the second end of the third bracket 23 and is also locked onto the first support member 3.

[0050] In this embodiment, the upper shelf 2 is snapped onto the first support member 3 by the third locking position 211 set on the first bracket 21 and the fourth locking position 221 set on the second bracket 22, so that the first support member 3 supports the upper shelf 2 and fixes the upper shelf 2.

[0051] Example 4

[0052] like Figures 1 to 4 As shown, in this embodiment, a first support member 3 is provided at the center of the first side of the lower shelf 1. The first support member 3 includes a first support rod 31 and a second support rod 32 extending vertically upward. The top ends of the first support rod 31 and the second support rod 32 are connected by a first connecting rod 33. The first connecting rod 33 has a first locking position 311 and a second locking position 321 at both ends that are U-shaped and open towards the outside of the lower shelf 1.

[0053] When installing the upper shelf 2, lift the upper shelf 2 upwards so that the first connecting rod 33 passes between the first bracket 21 and the second bracket 22. Then press the upper shelf 2 downwards so that the third locking position 211 is locked above the first locking position 311 and the fourth locking position 221 is locked above the second locking position 321, while the third bracket 23 is located below the first locking position 311 and the second locking position 321.

[0054] In this embodiment, after tableware is placed on the upper shelf 2, the upper shelf 2 experiences downward pressure from the tableware. Since the semi-circular third locking position 211 and fourth locking position 221 in the upper shelf 2 are respectively engaged with the first locking position 311 and the second locking position 321, the first locking position 311 and the second locking position 321 generate an upward supporting force on the upper shelf 2. Under this pressure, the upper shelf 2 rotates around the first locking position 311 and the second locking position 321, causing the third support 23 to rotate upward. Simultaneously, the third support 23 is located below the first locking position 311 and the second locking position 321. When the third support 23 rotates upward, it is blocked by the first locking position 311 and the second locking position 321, which exert a downward force on the third support 23, stopping its rotation.

[0055] In this embodiment, the upper shelf 2 has a simple structure and can be easily installed on the first support member 3, facilitating its installation or removal. This allows users to place tableware on the lower shelf 1 or remove it from the lower shelf 1. Simultaneously, the first support member 3 supports and secures the upper shelf 2, enabling the continued placement of tableware on it.

[0056] Example 5

[0057] like Figures 1 to 5 As shown, in this embodiment, a second support member 4 is provided on the second side of the lower shelf 1. The second side of the lower shelf 1 is adjacent to the first side of the lower shelf 1, and the second support member 4 is located at the end of the second side of the lower shelf 1 away from the first side of the lower shelf 1. The second support member 4 includes a third support rod 41 and a fourth support rod 42 extending vertically upward. The upper half of the third support rod 41 extends toward the side of the fourth support rod 42. A fifth support rod 44 extends horizontally from the top of the third support rod 41 toward the interior of the lower shelf 1. A sixth support rod 45 extends from the top of the fourth support rod 42 in a direction parallel to the fifth support rod 44 and has the same length as the fifth support rod 44. The fifth support rod 44 and the sixth support rod 45 are connected by a second connecting rod 43.

[0058] When installing the upper shelf 2, first snap the upper shelf 2 onto the first support member 3. After the upper shelf 2 is installed at the end closest to the first support member 3, place the fourth bracket 24 on the fifth support rod 44 and the sixth support rod 45. In this embodiment, after placing tableware on the upper shelf 2, the upper shelf 2 is subjected to downward pressure from the tableware, while simultaneously subjected to upward support from the second support member 4 on the fourth bracket 24, thus maintaining the balance of the upper shelf 2.

[0059] Example 6

[0060] like Figures 1 to 6As shown, in this embodiment, a third support member 5 is provided inside the lower shelf 1 near the center of the upper shelf 2. The third support member 5 is located between the water cup area 15 and the chopsticks area 16. The third support member 5 includes a seventh support rod 51 and an eighth support rod 52 extending vertically upwards, with the seventh support rod 51 and the eighth support rod 52 having the same height. The top ends of the seventh support rod 51 and the eighth support rod 52 are connected by a third connecting rod 53, which has a downwardly curved recess. A fourth connecting rod 25 is provided near the corner of the second bracket 22. The fourth connecting rod 25 has an upwardly curved protrusion, which rests on the recess of the third connecting rod 53, preventing the upper shelf 2 from shaking after tableware is placed on it.
