[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] The following is for reference. Figures 1-11 The bottom structure 100 of a dishwasher 1000 according to a first aspect embodiment of the present invention is described.

[0034] like Figures 1-11 As shown, the bottom structure 100 of the dishwasher 1000 according to the first aspect embodiment of the present invention includes: a base 1, a flow guide 2 and a sound insulation plate 3.

[0035] Specifically, the bottom structure 100 is adapted to be arranged on the lower side of the inner liner 200. The bottom structure 100 includes: a base 1, on which a hinge seat 11 is provided; a flow guide 2, at least a portion of which is located on the upper side of the base 1; and a sound insulation plate 3 is provided on the upper side of the base 1, and the sound insulation plate 3 is connected to at least one of the flow guide 2 and the hinge seat 11. Understandably, the base 1 is the basic support part of the dishwasher 1000. An overflow cavity is formed inside the base 1. The guide 2 is located at the bottom of the inner tank 200 and connected to the inner tank 200. The guide 2 is used to guide the water flow along a predetermined path. The guide plate introduces the overflow water into the overflow cavity and flows out of the dishwasher 1000 through the overflow hole at the bottom of the base 1. The sound insulation plate 3 is located at the bottom of the inner tank 200. The sound insulation plate 3 can be connected to the guide 2, and the sound insulation plate 3 can also be connected to the hinge seat 11. The sound insulation plate 3 can also be connected to both the guide 2 and the hinge seat 11. In this way, it helps to isolate the noise from the bottom of the inner tank 200 and the motor pump, as well as the noise from the water flow hitting the bottom wall of the inner tank 200, providing a quieter operating environment.

[0036] Reference Figures 1-8 As shown, the sound insulation panel 3 is located at the bottom of the inner liner 200, which is mounted on the base 1. The sound insulation panel 3 is connected to the airflow guide 2, thus providing sound insulation and noise reduction. (Refer to...) Figures 9-11 As shown, the sound insulation panel 3 is located at the bottom of the inner liner 200, which is located on the base 1. The sound insulation panel 3 is connected to the hinge seat 11.

[0037] According to the embodiment of the present utility model, the bottom structure 100 of the dishwasher 1000, by setting a sound insulation plate 3 that cooperates with the flow guide 2, effectively isolates the noise generated by the water flow impacting the bottom of the inner tank 200 and the motor pump, making the dishwasher 1000 quieter during operation and reducing the impact of operating noise on users. The sound insulation plate 3 is connected to the flow guide 2 and / or the hinge seat 11, realizing the integrated design of the sound insulation plate 3 and the flow guide 2 and / or the hinge seat 11, which facilitates modular assembly, improves production assembly efficiency, and has a compact overall structure and small space volume.

[0038] In some embodiments of this utility model, the sound insulation plate 3 has a first connecting portion, and the flow guide 2 has a second connecting portion. The sound insulation plate 3 and the flow guide 2 are connected by the first connecting portion and the second connecting portion. It is understood that the first connecting portion is formed on the sound insulation plate 3, and the second connecting portion is formed on the flow guide 2. The first connecting portion and the second connecting portion cooperate to connect the sound insulation plate 3 and the flow guide 2. Thus, the connection between the sound insulation plate 3 and the flow guide 2 is achieved through the mutual cooperation of the first connecting portion and the second connecting portion, allowing the sound insulation plate 3 to be stably and flexibly connected to the flow guide 2, reducing the problem of loosening or displacement of the sound insulation plate 3 due to vibrations generated during the operation of the dishwasher 1000.

[0039] In some embodiments of this utility model, one of the first connecting portion and the second connecting portion is formed as a connecting groove 31, and the other of the first connecting portion and the second connecting portion is formed as a connecting protrusion 21, which extends into the connecting groove 31. It can be understood that the first connecting portion can be formed as a connecting groove 31 and the second connecting portion as a connecting protrusion 21, or the first connecting portion can be formed as a connecting protrusion 21 and the second connecting portion as a connecting groove 31, with the connecting protrusion 21 extending into the connecting groove 31. In this way, the sound insulation plate 3 and the flow guide 2 are connected through the connecting protrusion 21 and the connecting groove 31, improving the connection stability and reliability between the sound insulation plate 3 and the flow guide 2.

[0040] Reference Figure 8 As shown, a connecting groove 31 is formed on the sound insulation panel 3. A first flange 32, a second flange 33, and a third flange 34 are formed on the sound insulation panel 3, connected sequentially. The first flange 32 and the third flange 34 extend vertically, while the second flange 33 extends horizontally. The lower end of the first flange 32 is connected to the sound insulation panel 3. The first flange 32, the second flange 33, and the third flange 34 together define the connecting groove 31. A connecting protrusion 21 is formed on the guide member 2. The connecting groove 31 extends along a first direction (e.g., ...). Figure 5 The guide member 2 extends along the first direction (as shown in the first direction), and the guide member 2 extends along the first direction (as shown in the first direction). Figure 5 Extending in the first direction shown, the connecting protrusion 21 is located within the connecting groove 31.

[0041] In some embodiments of this utility model, the sound insulation plate 3 is located between the inner liner 200 and the base 1, and sealing cotton is provided between the sound insulation plate 3 and the flow guide 2. It can be understood that the sound insulation plate 3, located between the inner liner 200 and the base 1, serves as a buffer layer to block noise transmission paths, reduce vibration transmission, and enhance structural stability. The sealing cotton is located between the sound insulation plate 3 and the flow guide 2; a portion of the sealing cotton is connected to the flow guide 2, and another portion is connected to the sound insulation plate 3. Alternatively, the upper surface of the sealing cotton is connected to the flow guide 2, and the lower surface is connected to the sound insulation plate 3. This allows for the absorption of some vibration energy, achieving both sealing and sound absorption. The sealing cotton also possesses certain compression resilience, which can compensate for manufacturing errors or installation deviations between parts during assembly.

[0042] In some embodiments of this utility model, the flow guide 2 has an overflow channel 24, and the sound insulation plate 3 has a receiving portion 35. At least a portion of the overflow channel 24 is located within the receiving portion 35. A first snap-fit ​​portion is formed on the outer wall of the overflow channel 24, and a second snap-fit ​​portion is formed on the side wall of the receiving portion 35. The flow guide 2 and the sound insulation plate 3 are connected by the engagement of the first snap-fit ​​portion and the second snap-fit ​​portion. It is understood that the first snap-fit ​​portion is formed on the outer wall of the overflow channel 24, the second snap-fit ​​portion is formed on the side wall of the receiving portion 35, the sound insulation plate 3 has an upwardly recessed receiving portion 35, and the flow guide 2 forms the overflow channel 24, with a portion of the overflow channel 24 located within the receiving portion 35. Thus, the connection between the flow guide 2 and the sound insulation plate 3 is achieved through the mutual engagement of the first and second snap-fit ​​portions, allowing the sound insulation plate 3 to be securely and flexibly connected to the flow guide 2, reducing the problem of loosening or displacement of the sound insulation plate 3 due to vibrations generated during the operation of the dishwasher 1000.

[0043] Furthermore, with the combined cooperation of the connection structure of the first connecting part and the second connecting part, as well as the connection structure of the first snap-fit ​​part and the second snap-fit ​​part, the flow guide 2 and the sound insulation plate 3 can achieve a more stable and reliable connection.

[0044] In some embodiments of this utility model, the guide member 2 includes a body 22 and a cover 23. A second connecting portion is formed on the body 22, and the cover 23 is connected to the body 22 to define an overflow channel 24. The cover 23 has a through hole 231. (See reference...) Figure 5 As shown, the cover 23 of the flow guide 2 and the body 22 together define the overflow channel 24. At least a portion of the cover 23 is located inside the receiving portion 35. A through hole 231 is formed on the cover 23 to facilitate the connection between the flow guide 2 and the sound insulation plate 3.

[0045] In some embodiments of this utility model, reference is made to Figure 5 As shown, the first engaging portion is formed as a protrusion 25, and the second engaging portion is formed as a hole 36. The protrusion 25 passes through the through hole 231 and extends into the hole 36. In this way, the sound insulation plate 3 and the flow guide 2 are connected by the engagement of the protrusion 25 and the hole 36, which improves the connection stability and reliability between the sound insulation plate 3 and the flow guide 2. Furthermore, the protrusion 25 passes through the through hole 231 of the cover 23 and extends into the hole 36, which not only achieves a stable connection between the sound insulation plate 3 and the flow guide 2, but also achieves the positioning and fixation of the cover 23, preventing displacement between the cover 23 and the body 22 during the operation of the dishwasher 1000.

[0046] In some embodiments of this utility model, the first connecting part is disposed on both sides of the overflow channel 24, and the second connecting part is disposed correspondingly to the first connecting part.

It can be understood that the third connecting portion is formed at the lower end of the sound insulation panel 3, and the fourth connecting portion is formed on the front sidewall of the base 1. The cooperation of the third connecting portion and the fourth connecting portion connects the sound insulation panel 3 to the base 1, thereby reducing the problem of loosening or displacement of the sound insulation panel 3 caused by vibration generated during the operation of the dishwasher 1000.

[0048] In some embodiments of this utility model, the third connecting portion is formed as the first connecting hole 37, and the fourth connecting portion is formed as the second connecting hole. The sound insulation plate 3 and the base 1 are connected by fasteners passing through the first connecting hole 37 and the second connecting hole. It is understood that, as Figures 9-10 As shown, the lower end of the sound insulation panel 3 is connected to the front side wall of the base 1 by fasteners passing through the first connection hole 37 and the second connection hole. In this way, the sound insulation panel 3 can be assembled from the front surface of the dishwasher 1000, which reduces the assembly difficulty of the sound insulation panel 3, facilitates assembly, and improves the connection stability and reliability between the sound insulation panel 3 and the base 1.

[0049] In some embodiments of this utility model, the sound insulation panel 3 has a first limiting part, and the hinge seat 11 has a second limiting part. The sound insulation panel 3 and the hinge seat 11 are connected by the cooperation of the first limiting part and the second limiting part. It can be understood that the first limiting part is formed on the sound insulation panel 3, and the second limiting part is formed on the hinge seat 11. The sound insulation panel 3 and the hinge seat 11 are pre-positioned by the cooperation of the first limiting part and the second limiting part, thereby determining the assembly position of the sound insulation panel 3 and ensuring accurate assembly position. Simultaneously, the first limiting part and the second limiting part cooperate to secure the connection using fasteners, thereby connecting the sound insulation panel 3 and the hinge seat 11. Thus, the connection between the sound insulation panel 3 and the hinge seat 11 is achieved through the cooperation of the first limiting part and the second limiting part, allowing the sound insulation panel 3 to be stably connected to the hinge seat 11, reducing the problem of loosening or displacement of the sound insulation panel 3 due to vibrations generated during the operation of the dishwasher 1000.

[0050] In some embodiments of this utility model, one of the first limiting part and the second limiting part is formed as a limiting groove 38, and the other of the first limiting part and the second limiting part is formed as a limiting block 111, with the limiting block 111 extending into the limiting groove 38. It can be understood that the first limiting part can be formed as the limiting groove 38 and the second limiting part as the limiting block 111, or the first limiting part can be formed as the limiting block 111 and the second limiting part as the limiting groove 38, with the limiting block 111 extending into the limiting groove 38. In this way, the sound insulation plate 3 and the hinge seat 11 are connected through the cooperation of the limiting block 111 and the limiting groove 38, improving the connection stability and reliability between the sound insulation plate 3 and the hinge seat 11.

[0051] Reference Figure 10 As shown, the first limiting part is formed as a limiting groove 38, and the second limiting part is formed as a limiting block 111, with the limiting block 111 extending into the limiting groove 38.

[0052] In some embodiments of this utility model, reference is made to Figure 10 As shown, the sound insulation panel 3 includes a first panel 39, a second panel 310, a third panel 311, and a fourth panel 312 connected in sequence. The first panel 39 and the third panel 311 extend horizontally, while the second panel 310 and the fourth panel 312 extend vertically. A notch is formed on the second panel 310, and the edge of the third panel 311, which seals the notch, defines a limiting groove 38. Thus, the sound insulation panel 3 has a three-dimensional bent structure, which allows it to better wrap around or fit the bottom of the inner liner 200. The size of each panel can be flexibly adjusted according to the actual internal space, improving assembly flexibility. The limiting groove 38 cooperates with the limiting block 111, reducing the assembly difficulty of the sound insulation panel 3 and the bottom of the hinge seat 11.

[0053] Furthermore, with the combined cooperation of the connection structures of the third and fourth connecting parts and the connection structures of the first and second limiting parts, the sound insulation panel 3 achieves a more stable and reliable connection.

[0054] Furthermore, as shown in the figure, in order to ensure the stable assembly of the sound insulation panel 3, the third plate 311 has a first assembly hole, and the limiting block 111 has a second assembly hole. The sound insulation panel 3 and the inner liner 200 are connected and limited by fasteners passing through the first and second assembly holes. The limiting groove 38 is formed in the sound insulation panel 3 in the first direction (e.g., Figure 9 The third plate 311 is located at both ends in the first direction (as shown in the first direction). Figure 9 Both ends of the first assembly hole are formed in the first direction shown.

[0055] In some embodiments of this utility model, sealing cotton is provided between the sound insulation panel 3 and the inner liner 200. It is understood that the sealing cotton between the sound insulation panel 3 and the inner liner 200 is used to block the noise transmission path, reduce vibration transmission, and enhance structural stability. The sealing cotton, placed between the sound insulation panel 3 and the inner liner 200, can absorb some vibration energy, thus playing a sealing and sound-absorbing role. The sealing cotton also has a certain degree of compression resilience, which can compensate for manufacturing errors or installation deviations between parts during assembly.
