Description

Technical Field

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

[0002] A dishwasher is a device used to process tableware through a series of processes, including loading, washing, rinsing, sterilizing and drying. It can not only handle a large number of tableware, improve the cleaning efficiency and reduce the workload of manual labor, but also ensure a stable cleaning effect.

[0003] In related technologies, existing dishwashers have a chassis and an electrical control box. During assembly, the electrical control box is placed directly onto the chassis and then connected and fixed using fasteners (such as bolts and screws). However, the first mounting hole of the electrical control box and the second mounting hole of the chassis require manual initial positioning during placement and manual secondary positioning during assembly. This makes the assembly process of the electrical control box more complicated, reduces assembly efficiency, and when the secondary positioning is inaccurate, the first mounting hole and the second mounting hole may misalign, resulting in the assembled quality not meeting expectations. Utility Model Content

[0004] This application provides a base assembly and a dishwasher, which can effectively solve the problem of low positioning efficiency and accuracy caused by the complicated positioning process of existing electrical control boxes during assembly.

[0005] In a first aspect, embodiments of this application provide a base assembly, the base assembly comprising:

[0006] An electrical control box, wherein a buckle is provided on the electrical control box;

[0007] The chassis has a fastening part with a slot. The slot has an insertion section and a fastening section communicating with the insertion section. At least a portion of the buckle can be inserted into the insertion section, and the buckle moves from the insertion section to the fastening section so that the buckle is fastened to the fastening part.

[0008] In one embodiment, the inserting section is a slot structure, and the fastening section is a bayonet structure that passes through the fastening portion; or,

[0009] Both the interlocking section and the fastening section are slot structures; or...

[0010] Both the interlocking section and the fastening section are bayonet structures that pass through the fastening part.

[0011] In one embodiment, the buckle includes a buckle base body and a buckle hook protrusion. The buckle hook protrusion is formed on the side wall of the buckle base body and abuts against the surface of the fastening section facing away from the electrical control box. The buckle base body is fixedly connected to the electrical control box.

[0012] In one embodiment, the width of the fastening segment is defined as the fastening width, and the length of the card holder body is equal to the fastening width along the protrusion direction F of the hook protrusion.

[0013] Alternatively, the length of the card holder body is less than the fastening width, and the sum of the length of the card holder body and the protrusion height of the hook protrusion is greater than the fastening width.

[0014] In one embodiment, the card holder body is formed with two hook protrusions, the two hook protrusions are respectively located on two opposite sidewalls of the card holder body, and both hook protrusions abut against the surface of the fastening section facing away from the electrical control box.

[0015] In one embodiment, along the width direction P of the interlocking section, the inner sidewall of the slot is formed with an anti-detachment limiting part, the anti-detachment limiting part is located between the interlocking section and the fastening section, and the buckle abuts against the anti-detachment limiting part to cause the anti-detachment limiting part to undergo elastic deformation.

[0016] In one embodiment, the slot further has an adjustment space, which is located between the insertion section and the fastening section, and the adjustment space is located outside the fastening section. The adjustment space is used to provide the space required by the anti-detachment limiting part during elastic deformation.

[0017] In one embodiment, along the width direction P of the interlocking section, the two opposite inner sidewalls of the slot are each formed with the anti-detachment limiting part, each slot is located between the interlocking section and the fastening section, and at least one of the two anti-detachment limiting parts is correspondingly configured with the adjustment space.

[0018] In one embodiment, the base assembly further includes a fastener, and the electrical control box has a fastening through hole, through which the fastener passes and is connected to the chassis.

[0019] In one embodiment, the portion of the top surface of the chassis that abuts against the electronic control box is an electronic control support surface, and the fastening part is located inside the electronic control support surface.

[0020] Secondly, embodiments of this application provide a dishwasher that includes the aforementioned base assembly.

[0021] Based on the above embodiments, the base assembly proposed in this application includes an electrical control box and a chassis. The chassis has a fastening part, and the electrical control box is provided with a buckle. The fastening part is provided with a slot, and the slot has an insertion section and a fastening section connecting the insertion section. At least some of the buckles can be inserted into the insertion section, and the buckles move from the insertion section to the fastening section so that the buckles are fastened to the fastening part.

[0022] Compared to related technologies, the technical solution of this application, through the cooperation of the buckle and the slot provided on the fastening part, can easily and efficiently position the electrical control box onto the chassis before it is pre-fixed to the chassis using fasteners, thus achieving the purpose of pre-fixation. This solves the problem of the existing electrical control box requiring secondary positioning during assembly, which leads to complicated positioning. It is convenient to operate and greatly improves positioning efficiency, thereby improving assembly efficiency. At the same time, it pre-fixes the electrical control box to the chassis under different conditions without the use of fasteners, preventing it from loosening or falling over, improving the stability and quality of assembly. It plays a convenient and quality-enhancing role in transportation, assembly turnover, and after-sales maintenance. Attached Figure Description

[0032] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0034] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] This application discloses a dishwasher for automatically washing and cleaning pots, pans, cups, etc. The dishwasher has an upper unit and a base assembly 012 fixedly connected to the upper unit. The upper unit is configured with, but is not limited to, a heating element for sterilizing and disinfecting tableware, a spray cleaning element for washing tableware, a drive element for rotating and / or moving the spray cleaning element, a temperature sensor for monitoring water temperature and / or heating temperature, a water level sensor for the washing water level, and a display control panel for displaying various information (washing time, disinfection time, washing stage, etc.). The base assembly 012 includes an electrical control box 1 and a chassis 2. The heating element, spray cleaning element, drive element, temperature sensor, and water level sensor are all electrically connected to the electrical control box 1. The electrical control box 1 can receive and process signals from the temperature sensor and the water level sensor, and convert the washing program input on the display control panel into control commands, which are then sent to the heating element, spray cleaning element, and drive element to regulate them. Of course, the control box 1 can also control the dishwasher's display control panel to show the user the current washing status.

[0038] In this embodiment, please refer to the following for details. Figures 1 to 6 As shown, the aforementioned electrical control box 1 is provided with a buckle 31, and the chassis 2 has a fastening part. The fastening part is provided with a slot 32, and the slot 32 has an insertion section 321 and a fastening section 322 that connects to the insertion section 321. At least part of the buckle 31 can be inserted into the insertion section 321, and the buckle 31 moves from the insertion section 321 to the fastening section 322, so that the buckle 31 is fastened to the fastening part. During the process of assembling the electrical control box 1 to the chassis 2, the buckle 31 of the electrical control box 1 is inserted into the insertion section 321, and then a force is applied to the electrical control box 1 to move the electrical control box 1 into the fastening section 322, and the buckle 31 engages with the fastening section 322. Thus, without using fasteners to pre-install and fix the electrical control box 1 to the chassis 2, the electrical control box 1 and the chassis 2 are connected by a snap-fit ​​connection, so as to pre-install and fix the electrical control box 1 to the chassis 2 more efficiently and easily.

[0039] In summary, the design only requires a buckle 31 in the control box 1 and a slot 32 in the mounting portion of the chassis 2. This simple structure facilitates manufacturing and reduces the production cost and assembly difficulty of the base assembly 012. Furthermore, the combination of the buckle 31 and the slot 32 allows for quick positioning of the control box 1 before pre-installation and fixation to the chassis 2 using fasteners, and facilitates subsequent reinforcement (such as bolting).

[0040] Preferably, the chassis 2 is defined as having a top surface and a base surface that are arranged opposite to each other. The base surface is the side of the chassis 2 that abuts against a building structure (such as a tabletop, ground, etc.), and the top surface is the side of the chassis 2 that abuts against and / or approaches the upper base. The direction of the chassis 2 from the base surface to the top surface is the height direction H of the chassis 2. The portion of the top surface that abuts against the electrical control box 1 is the electrical control support surface. Along the height direction H, the fastening part is located within the orthographic projection range of the electrical control support surface. The electrical control box 1 abuts against the electrical control support surface, and the latch 31 engages with the fastening section 322, effectively ensuring that the electrical control box 1 will not loosen or fall over, thereby improving the stability and quality of the assembly.

[0041] For example, please refer to the specific details. Figure 5 As shown, the number of slots 32 in the orthographic projection range of the electrical control support surface is preferably two, with the two slots 32 spaced apart. The number of latches 31 on the electrical control box 1 is correspondingly configured to be two, with each latch 31 engaging with each slot 32, thus allowing the electrical control box 1 to be more accurately positioned on the chassis 2. However, it should be noted that the number of slots 32 in the orthographic projection range of the electrical control support surface can also be three, four, five, etc., in which case the number of latches 31 on the electrical control box 1 can also be three, four, five, etc., the same as the number of slots 32 on the chassis 2, or fewer than the number of slots 32 on the chassis 2. The number of latches 31 on the electrical control box 1 and the number of slots 32 on the chassis 2 can be set and adjusted according to structural design and design requirements.

[0042] In addition, please refer to the specific details. Figure 6 As shown, along the height direction H, the shapes of the interlacing segment 321 and the fastening segment 322 are preferably rectangular, thus the interlacing segment 321 and the fastening segment 322 are combined to form a convex structure. Of course, the shapes of the interlacing segment 321 and the fastening segment 322 can also be adjusted according to the structural design and design requirements.

[0043] Understandably, in order for the buckle 31 to be inserted into the insertion section 321 and for the buckle 31 to move from the insertion section 321 to the fastening section 322, the buckle 31 can fasten the slot 32. The width of the insertion section 321 is the insertion width, and the width of the fastening section 322 is the fastening width. Since the insertion width is greater than the fastening width, during the process of the buckle 31 moving from the insertion section 321 to the fastening section 322, the contact area between the buckle 31 and the edge of the fastening section 322 gradually increases, thereby enabling the buckle 31 to be fastened onto the slot 32.

[0044] It should also be noted that the direction from the interpenetrating section 321 towards the fastening section 322 is defined as the fastening direction. The interpenetrating section 321 of the slot 32 is closer to the interior of the chassis 2, and the fastening section 322 of the slot 32 is closer to the exterior of the chassis 2, with the fastening direction pointing towards the outer side of the chassis 2. Conversely, if the interpenetrating section 321 of the slot 32 is closer to the exterior of the chassis 2, and the fastening section 322 of the slot 32 is closer to the interior of the chassis 2, the fastening direction points towards the inner side of the chassis 2.

[0045] As one of the preferred embodiments of this invention, please refer to the following for details. Figure 5 and Figure 6 As shown, both the insertion section 321 and the fastening section 322 are through-hole bayonet structures. During the assembly of the electrical control box 1 to the chassis 2, the buckle 31 will completely pass through the insertion section 321 until the electrical control box 1 abuts against the top surface of the chassis 2. Then, it will slide from the insertion section 321 onto the top surface of the chassis and move to the fastening section 322, thus achieving the purpose of snapping the electrical control box 1 and the chassis 2 together.

[0046] As another preferred embodiment, both the insertion section 321 and the fastening section 322 are slot structures. Specifically, the slot wall of the slot structure has a buckle protrusion. The buckle protrusion extends along the edge of the fastening section 322. When the part of the buckle 31 that extends into the slot structure moves to the fastening section 322, it can be engaged with the buckle protrusion, and the purpose of engaging the electrical control box 1 and the chassis 2 can also be achieved.

[0047] In one preferred embodiment, the insertion section 321 is a slot structure, and the fastening section 322 is a through-hole structure. The side of the slot structure close to the fastening structure is connected to the fastening structure. During the assembly of the electrical control box 1 to the chassis 2, the part of the buckle 31 extending into the slot structure abuts against the bottom of the slot structure. The bottom of the slot structure is inclined from the insertion section 321 toward the fastening section 322. When the electrical control box 1 is moved so that the part of the buckle 31 extending into the slot structure reaches the fastening section 322, under the action of the electrical control box 1, the electrical control box 1 will be able to abut against the top surface of the chassis 2, and the buckle 31 will be engaged at the edge of the fastening section 322.

[0048] Preferably, please refer to the following for details. Figures 1 to 4As shown, the buckle 31 includes a seat body 311 and a hook protrusion 312. The hook protrusion 312 protrudes from the side wall of the seat body 311 and abuts against the side of the engaging section 322. The seat body 311 is fixedly connected to the electrical control box 1. Specifically, the electrical control box 1 has an electrical control housing. The side of the electrical control housing closest to the chassis 2 is the bottom surface of the housing. The seat body 311 protrudes from the bottom surface of the housing along the height direction H of the chassis 2. The hook protrusion 312 is located at the end of the seat body 311 away from the bottom surface of the housing. When the hook protrusion 312 abuts against the side of the engaging section 322, the buckle 31 engages the slot 32, achieving the purpose of engaging the electrical control box 1 with the chassis 2.

[0049] Furthermore, please refer to the specific details. Figures 1 to 4 As shown, the card holder body 311 has two protruding hook protrusions 312, which are located on two opposite sidewalls of the card holder body 311 and abut against the side of the fastening section 322. With this arrangement, when the buckle 31 engages with the slot 32, each hook protrusion 312 abuts against both opposite sides of the fastening section 322, greatly increasing the contact area and ensuring even force distribution on both sides of the card holder body 311. This improves the stability and uniformity of the engagement.

[0050] In a preferred embodiment, along the protrusion direction F of the hook protrusion 312, the length of the card holder body 311 is equal to the engagement width. Here, "equal to" should be understood as meaning that the length of the card holder body 311 matches the engagement width of the engagement section 322, or, within the assembly tolerance range, the length of the card holder body 311 is less than the engagement width of the engagement section 322. Thus, when the buckle 31 engages with the slot 32, the card holder body 311 is constrained by the engagement section 322 and will not move along the width direction P, achieving precise positioning.

[0051] In another preferred embodiment, the length of the card holder body 311 is less than the engagement width, and the sum of the length of the card holder body 311 and the protrusion height of the hook protrusion 312 is greater than the engagement width. The length of the card holder body 311 is the dimension of the card holder body 311 along the protrusion direction F of the hook protrusion 312. When both opposite sidewalls of the card holder body 311 are formed with hook protrusions 312, the sum of the length of the card holder body 311 and twice the protrusion height of the hook protrusion 312 is greater than the engagement width, so as to ensure that each hook protrusion 312 can abut against the side of the engagement section 322.

[0052] In the above, the cooperation of the buckle 31 and the slot 32 effectively ensures efficient and accurate positioning of the electrical control box 1 and the chassis 2 during the assembly process, thereby improving the assembly efficiency of the base assembly 012. However, during the assembly process, the assembly personnel may accidentally touch the electrical control box 1, causing it to become misaligned. That is, when the electrical control box 1 is accidentally touched and subjected to force, at least part of the buckle 31 may shift into the insertion section 321, requiring the electrical control box 1 to be repositioned during subsequent reinforcement.

[0053] To address the above problems, the inventors also provide a preferred embodiment, as detailed in sections 1 to 2010. Figure 4 As shown, along the width direction P of the interpenetrating section 321, the inner sidewall of the slot 32 is formed with an anti-detachment limiting part 323. The slot 32 is located between the interpenetrating section 321 and the fastening section 322. The anti-detachment limiting part 323 can be hemispherical, triangular, or trapezoidal in the height direction H of the chassis 2. The anti-detachment limiting part 323 can be integrally formed with the chassis 2 to facilitate processing and manufacturing and ensure the overall performance.

[0054] During assembly, when a force is applied to the control box 1, the latch 31 abuts against the anti-detachment limiting part 323, causing the latch 31 to undergo elastic deformation. The latch 31 can then move from the insertion section 321 into the engagement section 322, quickly positioning the control box 1 onto the chassis 2. Alternatively, the latch 31 can move from the engagement section 322 into the insertion section 321, detaching the control box 1 from the chassis 2. After assembly and positioning, without external force or accidental contact, the latch 31 cannot compress the anti-detachment limiting part 323 to undergo elastic deformation, thus better confining the latch 31 within the engagement section 322 and preventing the need for repositioning the control box 1 in case of accidental contact or force.

[0055] Preferably, the slot 32 also has an adjustment space 324, which is located between the insertion section 321 and the fastening section 322, and is situated outside the fastening section 322. The adjustment space 324 is preferably a through hole, preferably circular, but can also be square, elliptical, or other shapes. Alternatively, the adjustment space 324 can be a recessed groove, providing the space required by the anti-detachment limiting part 323 during elastic deformation. That is, when the anti-detachment limiting part 323 is abutted by the buckle 31, the anti-detachment limiting part 323 will undergo elastic deformation towards the adjustment space 324. Therefore, under the action of the adjustment space 324, the anti-detachment limiting part 323 is more likely to undergo elastic deformation when it is squeezed by the buckle 31, thereby reducing the installation resistance of the control box 1, which is beneficial to the assembly between the control box 1 and the chassis 2. At the same time, it also greatly reduces the wear of the buckle 31.

[0056] Furthermore, along the width direction P of the interpenetrating section 321, the inner walls of the two opposite sides of the slot 32 are each formed with an anti-detachment limiting part 323. The two anti-detachment limiting parts 323 are arranged opposite to each other. Each slot 32 is located between the interpenetrating section 321 and the fastening section 322. At least one of the two anti-detachment limiting parts 323 is correspondingly provided with an adjustment space 324, that is, the number of adjustment spaces 324 is configured as one. The adjustment space 324 is used to provide the space required by one of the two anti-detachment limiting parts 323 during elastic deformation. Alternatively, the number of adjustment spaces 324 is configured as two, with each adjustment space 324 corresponding to each anti-detachment limiting part 323. Then, each anti-detachment limiting part 323 can generate elastic deformation towards the corresponding adjustment space 324 when it is squeezed by the buckle 31, thereby further reducing the installation resistance of the electrical control box 1 and further reducing the wear of the buckle 31.

Since the dishwasher proposed in the embodiments of this application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be repeated here.
