Technical Field

[0001] This application relates to the field of dishwasher technology, and in particular to a dishwasher base assembly and a dishwasher. Background Technology

[0002] Dishwashers, as a common kitchen appliance, bring great convenience to people's daily lives. The motor inside the dishwasher is the core power source for its dishwashing function, and these motors are usually located near the dishwasher base. During operation, the motor inevitably generates noise. To reduce the impact of noise on users, the industry commonly uses soundproofing panels installed at the dishwasher base.

[0003] In the dishwasher assembly process, there is a pre-assembly step for sound insulation panels. Before assembling the dishwasher base onto the complete machine, the sound insulation panels are typically pre-installed on the base, forming the base assembly. This base assembly is then assembled onto the complete machine. Currently, the connection between the dishwasher base and the sound insulation panels is primarily achieved using screws.

[0004] However, screw connection is a relatively complex operation. In actual operation, screwdrivers and other tools are needed to tighten each screw one by one, which is time-consuming and laborious, and seriously affects the assembly efficiency of the dishwasher. Utility Model Content

[0005] This application provides a dishwasher base assembly and a dishwasher, with a simple pre-assembly process and high dishwasher assembly efficiency.

[0006] To achieve the above objectives, a first aspect of this application provides a dishwasher base assembly, including a base and a sound insulation plate. The base includes a chassis, a guide structure, and a limiting buckle. The chassis has a first side, and the guide structure and the limiting buckle are connected to the first side.

[0012] In some embodiments, the guide structure includes a first clamping arm and a second clamping arm that are connected and spaced apart, and the slot is the space enclosed by the first clamping arm and the second clamping arm.

[0013] In some embodiments, the first clamping arm is closer to the center of the chassis than the second clamping arm, and the first clamping arm is higher than the second clamping arm.

[0014] In some embodiments, one side of the soundproof panel has a folded edge, and the retaining buckle presses against the folded edge to fasten the soundproof panel into the slot.

[0015] In some embodiments, the base further includes a limiting block connected to the first side, and one side of the sound insulation panel has a limiting notch that mates with the limiting block.

[0016] A second aspect of this application provides a dishwasher, comprising:

[0017] The main body includes an outer shell and an inner liner disposed within the outer shell; and

[0018] In any of the dishwasher base assemblies described above, the chassis further has a mounting cavity, the inner liner is mounted on the mounting cavity, and the other side of the sound insulation panel is connected to the inner liner.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] In the assembly and production process of dishwashers, to improve assembly efficiency, sound insulation panels are typically pre-installed onto the dishwasher base, forming a dishwasher base assembly, which is then assembled onto the complete machine. The pre-installation of sound insulation panels onto the base is crucial for improving dishwasher assembly efficiency. Therefore, this application provides a dishwasher assembly and a dishwasher to enhance dishwasher assembly efficiency.

[0037] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the dishwasher provided in this embodiment; Figure 2 This is a schematic diagram of the structure of the dishwasher base assembly provided in this embodiment; Figure 3 This is a structural schematic diagram of the dishwasher base assembly provided in this embodiment from another perspective.

[0038] The dishwasher in this embodiment includes a base assembly 1 and a dishwasher body 2. The dishwasher base assembly 1 is an important supporting structure for the entire dishwasher, and the dishwasher body 2 is mounted on the dishwasher base assembly 1. The dishwasher body 2 includes an outer shell and an inner tub. The outer shell serves as the external protective structure of the dishwasher, providing protection and support for the inner tub, and its shape can be cylindrical, square, etc. The inner tub is located inside the outer shell and is the part that directly contacts the tableware, containing the tableware and washing water during the washing process.

[0039] The inner drum is equipped with a water spray structure for washing dishes. This structure may include a rotating spray arm, a spray pipe with multiple nozzles, and other components. The main body 2 also includes a water system that supplies water to the water spray structure. This water system includes various components that primarily generate noise during dishwasher operation, such as a motor and a water pump. These components are mounted on the dishwasher base assembly 1. The motor generates vibration noise during the operation of its transmission components, and the water pump also generates noise during water pumping and draining due to mechanical movement and water flow impact.

[0040] To reduce noise, the dishwasher base assembly 1 in this embodiment includes a base 11 and a sound insulation plate 12. The base 11 is a crucial support structure for the entire dishwasher, comprising a chassis 111 with four sides: a first side 10, a second side 20, a third side 30, and a fourth side 40. The first side 10 is located at the front of the chassis 111; this refers to the side of the chassis 111 closest to the user during normal use. The four sides and the bottom wall of the chassis 111 together form a mounting cavity 300, on which the inner liner is mounted. Generally, some electrical components of the dishwasher, such as the control box, are mounted on the first side 10. To make room for these components, the first side 10 is typically lower than the other sides. Therefore, noise is more easily transmitted from the first side 10 of the chassis 111, thus affecting the user experience.

[0041] Therefore, in this embodiment, the sound insulation panel 12 is installed on the front side of the chassis 111 to reduce noise transmission. Specifically, the base 11 in this embodiment also includes a guide structure 112 and a limiting buckle 113, both of which are connected to the first side 10 of the chassis 111. The guide structure 112 is provided with a slot 100, the shape of which matches one side of the sound insulation panel 12 to achieve a plug-in fit. The limiting buckle 113 is used to securely fasten the sound insulation panel 12 to the slot 100 after it is inserted into the slot 100, preventing it from loosening or falling out.

[0042] In this embodiment, the sound insulation panel 12 can be a metal plate, and it can be bent to allow the operator to hold the bent portion of the panel and insert one side of the other bent portion into the slot 100. One side of the sound insulation panel 12 is pre-installed on the front of the base 11 through insertion into the slot 100 of the guide structure 112 and the fastening action of the limiting buckle 113. The other side of the sound insulation panel 12 is connected to the inner liner, thereby effectively reducing the transmission of noise on the front of the base 11.

[0043] In this embodiment, the installation method of the sound insulation panel 12 greatly improves assembly efficiency. By inserting the sound insulation panel 12 along the slot 100 and then fastening it with the limiting buckle 113, this simple and direct operation replaces the traditional screw fixing method. Compared with the traditional method, it eliminates the need for tools such as screwdrivers, avoiding the tedious process of tightening screws one by one. Operators can quickly and easily complete the pre-installation of the sound insulation panel 12 on the base 11, greatly saving assembly time and labor costs. In large-scale dishwasher production, this convenient assembly method can significantly increase the speed of the entire assembly line and improve production efficiency.

[0044] Please see Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the dishwasher base 11 provided in this embodiment; Figure 5 for Figure 4 Enlarged view of point A in the middle.

[0045] The slots 100 are arranged in different ways on the first side 10 of the chassis 111. In one embodiment, multiple slots 100 are provided, and the multiple slots 100 are distributed at intervals along the first side 10. The first side 10 is the side of the chassis 111 closest to the human body, and its length is adapted to one side of the sound insulation panel 12. The shape of the slots 100 is adapted to the corresponding part of the sound insulation panel 12 to ensure that the sound insulation panel 12 can be smoothly inserted into each slot 100 during insertion. This design of multiple slots 100 distributed at intervals means that when the sound insulation panel 12 is connected to the chassis 111, it is not a single-point connection, but is connected to the chassis 111 through multiple spaced connection points.

[0046] Because of the presence of multiple slots 100, multiple connection points are formed between the sound insulation panel 12 and the chassis 111. Under the condition of slight external impact, the multiple connection points can share the force, avoiding the problem of loosening due to excessive force on a single point, thereby enhancing the stability of the connection between the sound insulation panel 12 and the chassis 111.

[0047] In another embodiment, the slot 100 is elongated and extends along the length of the first side 10 of the chassis 111. The length of the elongated slot 100 is adapted to one side of the sound insulation panel 12, that is, one side of the sound insulation panel 12 can fit tightly against the slot 100 along the entire length of the elongated slot 100. The internal shape and size of the elongated slot 100 can be designed according to the side shape and thickness of the sound insulation panel 12 to ensure a tight fit between the two.

[0048] The adaptability of the elongated slot 100 to one side of the sound insulation panel 12 increases the contact area between them. This larger contact area allows for more even force distribution, preventing excessive localized stress that could cause the sound insulation panel 12 to loosen or shift. Simultaneously, the tight fit between the elongated slot 100 and the sound insulation panel 12 creates a continuous and stable sound barrier at their connection point, effectively preventing noise from propagating outwards from the first side 10 of the chassis 111, further enhancing the overall sound insulation performance of the dishwasher.

[0049] Furthermore, the slot 100 has its opening facing vertically upwards. Because the slot 100's opening is vertically upwards, the soundproofing panel 12 can naturally fall into the slot 100 under its own weight during installation. Compared to slots 100 in horizontal or other orientations, the slot 100 in this embodiment significantly reduces the external force required by the operator during insertion. The operator only needs to align the soundproofing panel 12 with the top of the slot 100 and guide it slightly; the soundproofing panel 12 can then be smoothly inserted under gravity, saving physical effort. Especially during large-scale production, the upward-facing slot design of this embodiment effectively reduces operator fatigue and improves work efficiency during prolonged installation operations. In addition, from a top-down view, the vertically upward-facing slot provides the operator with a clear alignment target. During installation, the operator can easily observe the relative position of the soundproofing panel 12 and the slot 100, allowing for more accurate alignment of the soundproofing panel 12 with the slot 100. This reduces the difficulty of alignment during installation, minimizes installation errors caused by inaccurate alignment, and improves the success rate and efficiency of installation.

[0050] Furthermore, the slot 100 has a constricting opening in the vertically downward direction. The constriction gradually decreases from top to bottom, forming a funnel-like guide shape, the internal dimensions and shape of which are adapted to the side of the sound insulation panel 12. This constricting opening serves as a guide during installation. When the operator moves the sound insulation panel 12 into the slot 100, even if the sound insulation panel 12 is not perfectly aligned with the slot 100 in the initial position, the constricting shape of the opening guides the sound insulation panel 12 gradually into the correct position. Just as a funnel guides an object into a narrow passage, this allows the sound insulation panel 12 to be guided more smoothly into the slot 100, reducing the precision required of the operator.

[0051] The design of the groove's contraction shape provides automatic alignment and guidance, greatly reducing installation errors that may occur due to inaccurate insertion of the sound insulation panel 12, and improving the reliability and stability of the installation process.

[0052] Please continue reading. Figure 5In some embodiments, the guide structure 112 consists of a first clamping arm 1121 and a second clamping arm 1122 that are interconnected and spaced apart. The slot 100 is the space enclosed by the first clamping arm 1121 and the second clamping arm 1122. That is, the two clamping arms together form the slot 100, which is used to accommodate the side of the sound insulation panel 12. The first clamping arm 1121 and the second clamping arm 1122 are spaced apart in the front-rear direction of the chassis 111, thereby defining the position of the sound insulation panel 12 in the front-rear direction of the chassis 111. Specifically, the first clamping arm 1121 and the second clamping arm 1122 provide stable positioning for the sound insulation panel 12 in the front-rear dimension of the chassis 111, so that the sound insulation panel 12 will not move arbitrarily in the front-rear direction after installation, ensuring the accuracy and stability of its position.

[0053] Furthermore, the first clamping arm 1121 and the second clamping arm 1122 have a specific positional and dimensional relationship. The first clamping arm 1121 is closer to the center of the chassis 111 than the second clamping arm 1122; that is, in the front-rear direction of the chassis 111, the first clamping arm 1121 is located behind the second clamping arm 1122. Also, in terms of height, the first clamping arm 1121 is higher than the second clamping arm 1122.

[0054] The aforementioned clamping arm design greatly facilitates the installation of the sound insulation panel 12. Since the first clamping arm 1121 is located at the rear and higher than the second clamping arm 1122 at the front, the operator does not need to precisely align the panel with the slot 100 as in traditional installation methods. Simply place one side of the sound insulation panel 12 against the rear-mounted first clamping arm 1121 and slide it downwards along it; the sound insulation panel 12 will then smoothly insert into the slot 100 formed by the first and second clamping arms 1121. This installation method simplifies the process and reduces the precision requirements for the operator. It significantly improves installation efficiency during large-scale dishwasher production and assembly. Furthermore, traditional slot 100 installation methods may be prone to errors due to the need for precise alignment, such as incorrect insertion angle of the sound insulation panel 12 or damage to the slot 100. This embodiment effectively avoids these problems by utilizing the position and height advantages of the first clamping arm 1121. The operator has greater operational tolerance during installation, reducing installation errors caused by human factors.

[0055] Please see Figure 4 , Figure 6 , Figure 7 and Figure 8 , Figure 6 for Figure 3 Enlarged view of point B in the middle; Figure 7 for Figure 4 Enlarged view of point C in the middle; Figure 8 This is a schematic diagram of the sound insulation panel 12 in this embodiment.

[0056] In some embodiments, the retaining buckle 113 extends along the height direction of the chassis 111 and has a hook at its end. The sound insulation panel 12 has a folded edge 121 on one side. When the sound insulation panel 12 is inserted into the slot 100 formed by the guide structure 112, the hook of the retaining buckle 113 presses against the folded edge 121 on the side of the sound insulation panel 12, thereby fastening the sound insulation panel 12 onto the slot 100. The cooperation between the retaining buckle 113 and the folded edge 121 of the sound insulation panel 12 limits the position of the sound insulation panel 12 in the height direction. The hook of the retaining buckle 113 engages with the folded edge 121, preventing the sound insulation panel 12 from moving upwards or downwards, ensuring that the sound insulation panel 12 is always in the set installation position.

[0057] Furthermore, there are two limiting buckles 113, and these two limiting buckles 113 are respectively disposed at both ends of the first side 10 of the chassis 111, so as to simultaneously limit the sound insulation panel 12 from both ends of the first side 10. In this embodiment, the two limiting buckles 113 are respectively located at both ends of the first side 10, which improves the stability of the sound insulation panel 12 after installation. During the installation process, when the sound insulation panel 12 is inserted into the slot 100, the limiting buckles 113 at both ends simultaneously fix the sound insulation panel 12 from both ends. This avoids the sound insulation panel 12 from shaking or shifting in the vertical direction, making the installation of the sound insulation panel 12 on the chassis 111 more secure and stable.

[0058] In some embodiments, the base 11, in addition to the structure described above, also includes a limiting block 114. The limiting block 114 is connected to the first side 10 of the chassis 111, and the limiting block 114 can be a suitable geometric shape such as a square with a certain shape and size. Correspondingly, one side of the sound insulation panel 12 is provided with a limiting notch 200 that mates with the limiting block 114. During assembly, the limiting block 114 is inserted into the limiting notch 200, and the two form a tight fit. The sidewall of the limiting block 114 can restrict the movement of the sound insulation panel 12 in the left-right direction of the chassis 111, thereby adding a dimensional constraint to the positioning of the sound insulation panel 12 on the chassis 111.

[0059] As mentioned above, the installation process of the sound insulation panel 12 in this embodiment is as follows: When installing the sound insulation panel 12, first align one side of the sound insulation panel 12 with the multiple slots 100 on the first side 10 of the chassis 111. Since the slot 100 opening is vertically upward and the first clamping arm 1121 in the guide structure 112 is higher than the second clamping arm 1122, the sound insulation panel 12 can be easily inserted along the first clamping arm 1121 under the action of gravity. The slot 100 initially positions the sound insulation panel 12 in the front-back direction of the chassis 111. During the insertion process, the limiting notch 200 on the side of the sound insulation panel 12 cooperates with the limiting block 114 on the first side 10 of the chassis 111. The limiting block 114 is embedded therein, and the side wall of the limiting block 114 restricts the movement of the sound insulation panel 12 in the left-right direction of the chassis 111. After the sound insulation panel 12 is fully inserted into the slot 100, the hooks of the limiting buckles 113 at both ends of the first side 10 hook onto the side folded edge 121 of the sound insulation panel 12, fixing the sound insulation panel 12 in the height direction of the chassis 111. Through the combined action of the slot 100, the limiting buckles 113, and the limiting block 114, the sound insulation panel 12 is omnidirectionally limited, improving the stability of the installation of the sound insulation panel 12, and making the installation convenient and efficient, without the need for complex alignment adjustments, thus improving assembly efficiency.
