Description

Technical Field

[0001] This disclosure relates to the field of kitchen appliances technology, and more particularly to a dishwasher. Background Technology

[0002] Dishwashers, as household appliances for cleaning dishes, not only free up your hands but are also more water-saving and environmentally friendly, and are being accepted and recognized by more and more users.

[0003] Dishwashers typically use a power supply box to control the power to their internal mechanisms. Currently, the power supply box and the dishwasher housing are mostly connected using bolts. This makes installation and maintenance cumbersome, hindering efficiency, and also carries the risk of loss, easily leading to connection failure. A few dishwashers use snap-on or sliding rail connections for the power supply box, but these are structurally complex and require numerous connectors at the four corners, which is detrimental to cost reduction and efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this disclosure provides a dishwasher.

[0005] This disclosure provides a dishwasher, including: case; An inner liner is disposed within the shell and is used to hold and wash tableware; A power supply box, connected to the housing, is used for power supply control; A connecting component is disposed on one of the power supply box and the housing, and the other of the two is provided with a through hole that mates with the connecting component; The connecting component includes a first connecting part and a second connecting part that are disposed opposite to each other. The first connecting part and the second connecting part are staggered in height. The first connecting part extends into the through hole and engages with one side wall of the through hole. The second connecting part is elastically engaged with the other side wall of the through hole. The axial ends of the through hole are clamped and limited between the first connecting part and the second connecting part.

[0006] Therefore, the power supply box and the housing can be quickly disassembled and connected through the connection components and through holes. The connection components have a simple overall structure and a flexible limiting and snap-fit ​​effect, making them easy to install and remove, and effectively achieving a simple and efficient connection between the housing and the power supply box.

[0007] In some embodiments, the second connecting portion includes an elastic arm and a snap-fit ​​portion. One end of the elastic arm is a free end that can be bent under pressure. The snap-fit ​​portion is disposed on the elastic arm and close to the free end, and is used to snap-fit ​​with the through hole. Thus, the second connecting portion achieves elastic snap-fit ​​with the through hole through the elastic arm and the snap-fit ​​portion. The overall structure of the second connecting portion is simple, and it can achieve reliable and effective elastic snap-fit.

[0008] In some embodiments, the end of the snap-fit ​​portion that contacts the through hole has an inclined slope, which slopes towards the free end. Thus, guided by the slope, the snap-fit ​​portion can more easily slide into the through hole and abut against and be positioned against the inner peripheral wall of the through hole.

[0009] In some embodiments, friction protrusions are provided on the slope surface. This increases the contact friction between the locking part and the through hole, effectively preventing the locking part from easily detaching from the through hole.

[0010] In some embodiments, the second connecting portion further includes a rib, which is disposed on the elastic arm and located between the first connecting portion and the snap-fit ​​portion. The rib can abut against the housing to bend the elastic arm. Thus, under the action of the rib, the elastic arm can undergo a large bending deformation, giving it more elastic potential energy, and thereby pushing the snap-fit ​​portion into the through hole with a greater elastic restoring force, thereby improving the reliability of the elastic snap-fit.

[0011] In some embodiments, a first limiting portion extending into the inner periphery of the through hole is provided on the side of the through hole that abuts against the first connecting portion, and a second limiting portion is correspondingly provided on the first connecting portion. The first limiting portion and the second limiting portion engage in a snap-fit ​​relationship. Thus, the first limiting portion and the second limiting portion engage in a snap-fit ​​relationship to further improve the limiting reliability of the first connecting portion and the through hole.

[0012] In some embodiments, the connection assembly includes at least two first connection portions spaced apart, wherein at least one first connection portion is provided with a second connection portion; at least two through holes are provided corresponding to the first connection portions. Thus, the connection assembly may include multiple first connection portions to improve the connection reliability between the power supply box and the housing.

[0013] In some embodiments, the connecting assembly further includes a support rib connected to the two first connecting portions, the support rib abutting and supporting between the power supply box and the housing. Thus, when the first connecting portion, the second connecting portion, and the through hole are engaged, the support rib can tightly abut and support between the power supply box and the housing, further improving the reliability of the support between the power supply box and the housing.

[0014] In some embodiments, the connection assembly further includes fasteners, a connecting seat integrally formed on the support rib, and mounting holes for the fasteners to pass through. The fasteners pass through the mounting holes and connect to the connecting seat to secure the power box and the housing. Thus, the connection reliability between the power box and the housing can be further enhanced by the fasteners.

[0015] In some embodiments, the connection assembly further includes a support member disposed on the back panel of the power supply box for abutting and supporting the power supply box. Thus, the support member can be positioned appropriately according to actual needs to abut and support the power supply box, preventing it from shaking. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0022] Dishwashers, as household appliances for cleaning dishes, not only free up your hands but are also more water-saving and environmentally friendly, and are being accepted and recognized by more and more users. They are mainly composed of a shell, power box, inner tub, dish rack, water spray pipe, water pump and other components. The inner tub has a cleaning chamber, and the dish rack can slide in the cleaning chamber to hold the dishes.

[0023] The power supply box includes a power supply box shell and a power board installed inside the power supply box shell. The power board is used for power supply control of the dishwasher. Its main function is to realize voltage and current changes, thereby powering and controlling the various electrical components inside the dishwasher.

[0024] Currently, the connection between the power supply box and the dishwasher housing is mostly achieved using bolt fasteners. This is cumbersome for manual installation and disassembly, and there's a risk of fasteners being lost. With prolonged use, the bolts are prone to loosening, leading to connection failure. A few dishwashers use snap-fit ​​or sliding rail connections for the power supply box, but these are structurally complex and require numerous connectors at the four corners of the power supply box, increasing manufacturing difficulty.

[0025] In view of this, the dishwasher of this application embodiment is provided with a connecting component on one of the housing and the power box. Its overall structure is simple and has an elastic limiting and snap-fit ​​effect, making it easy to install and remove, and can effectively realize a simple and efficient connection between the housing and the power box.

[0026] The specific structure and function of the dishwasher in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] This embodiment proposes a dishwasher, such as Figure 1 and Figure 2As shown, it includes a shell 1, an inner liner (not shown in the attached diagram), a power supply box 2, and a connecting assembly 3. The inner liner is disposed inside the shell 1 and is used to place and wash tableware. The power supply box 2 is connected to the shell 1 and is used for power supply control. In this embodiment, the power supply box 2 is a conventional component in the field, which includes a power supply box outer shell and a power board. The power supply box outer shell meets the requirements for insulation, waterproofing, etc., and the power board is encapsulated in the power supply box outer shell. In this embodiment, the power supply box 2 is detachably connected to the shell 1 through the connecting assembly 3. The connecting assembly 3 can be disposed in either the power supply box 2 or the shell 1, and the other of the two is provided with a through hole 4 that cooperates with the connecting assembly 3.

[0028] For example, such as Figure 2 As shown, in this embodiment, the connecting component 3 is disposed on the back of the power supply box 2, and the through hole 4 is disposed on the housing 1, specifically on the base portion of the housing 1. The connecting component 3 and the through hole 4 cooperate to achieve detachment and connection. However, in some other embodiments, the connecting component 3 can also be disposed on the base of the housing 1, and the through hole 4 can be opened on the back of the power supply box 2 to achieve a mating connection. However, to ensure the overall waterproofness of the power supply box 2, it is best to avoid opening holes on the power supply box 2. Therefore, it is preferable to dispose of the through hole 4 on the housing 1 and place the connecting component 3 on the back of the power supply box 2.

[0029] Furthermore, such as Figure 3 and Figure 4 As shown, the connecting component 3 includes a first connecting part 31 and a second connecting part 32 that are disposed opposite to each other, with the first connecting part 31 and the second connecting part 32 being staggered in height. Figure 5 and Figure 6 As shown, the via 4 in this embodiment has an overall strip-shaped hole structure. During assembly, as... Figure 7 and Figure 8As shown, the first connecting part 31 extends into the through hole 4 and engages with one side wall of the through hole 4, while the second connecting part 32 elastically engages with the other side wall of the through hole 4. The axial ends of the through hole 4 are clamped and limited between the first connecting part 31 and the second connecting part 32, thereby achieving the connection assembly between the connecting component 3 and the through hole 4. Specifically, in use, the first connecting part 31 is first aligned with the through hole 4, allowing the first connecting part 31 to pass through the through hole 4. Then, the power box 2 is pushed as a whole in the direction away from the second connecting part 32. The first connecting part 31 moves synchronously and engages with one axial side of the through hole 4. When the first connecting part 31 and the through hole 4 are engaged in place, the second connecting part 32 elastically engages with the through hole 4. The axial ends of the through hole 4 are clamped and limited between the first connecting part 31 and the second connecting part 32, which are offset in height, so that the power box 2 is fixedly connected to the housing 1, thereby achieving the connection assembly between the connecting component 3 and the through hole 4. During disassembly, since the second connecting part 32 and the through hole 4 are elastically engaged, the second connecting part 32 can be manually moved to disengage and unlock from the through hole 4. Then, the power box 2 is pushed, and the first connecting part 31 is unlocked from the through hole 4 and comes out of the through hole 4, thus achieving quick disassembly.

[0030] In some embodiments, such as Figure 8 As shown, the second connecting part 32 includes an elastic arm 321 and a snap-fit ​​part 322. The elastic arm 321 is a cantilever structure that can be bent and deformed. It is connected to the first connecting part 31. One end of the elastic arm 321 is a free end that can be bent under pressure. The snap-fit ​​part 322 is disposed on the elastic arm 321 and is disposed near the free end. The snap-fit ​​part 322 is used to snap-fit ​​with the through hole 4. When the first connecting part 31 extends into the through hole 4, the locking part 322 on the elastic arm 321 presses against the inner wall of the housing 1 to push the elastic arm 321 to bend away from the housing 1. When the first connecting part 31 extends into the through hole 4 and moves away from the second connecting part 32, the elastic arm 321 and its locking part 322 move synchronously. When the first connecting part 31 moves into place and locks into the through hole 4, the locking part 322 no longer abuts against the inner wall of the housing 1. The elastic arm 321 bends towards the through hole 4 to restore its deformation. At this time, the locking part 322 is pushed into the through hole 4 by the elastic arm 321, achieving elastic locking with the through hole 4. During disassembly, the elastic arm 321 is manually moved away from the through hole 4. The elastic arm 321 bends under force, and the locking part 322 disengages from the through hole 4, achieving elastic unlocking. The second connecting part 32 has a simple structure and can achieve a reliable and effective elastic snap-fit. In addition, the second connecting part 32 can also be an elastic snap-fit ​​structure of other structural forms. The structural forms of the second connecting part 32 include, but are not limited to, those shown in the accompanying drawings of this embodiment. Any snap-fit ​​structure with an elastic snap-fit ​​method falls within the protection scope of this application. This embodiment does not list all other structural forms of the second connecting part 32.

[0031] In some embodiments, such as Figure 8 and Figure 10 As shown, the end of the snap-fit ​​part 322 that contacts the through hole 4 has an inclined slope 3221. The slope 3221 is inclined towards the free end. Under the guidance of the slope 3221, the snap-fit ​​part 322 can easily slide into the through hole 4 and abut against the inner peripheral wall of the through hole 4 to achieve elastic snap-fit.

[0032] Based on this, in some embodiments, such as Figure 10 As shown, friction protrusions 3222 may also be provided on the slope 3221 to increase the friction between the locking part 322 and the inner peripheral wall of the through hole 4, so as to prevent the locking part 322 from easily disengaging from the through hole 4. For example, the friction protrusions 3222 may be a stepped structure provided along the slope of the slope 3221. In addition, the friction protrusions 3222 may also be striped or dotted protrusions, including but not limited to the forms shown in the figure of the embodiment.

[0033] In some embodiments, such as Figure 8 As shown, the second connecting part 32 also includes a rib 323. The rib 323 is located on the elastic arm 321 and is spaced between the first connecting part 31 and the snap-fit ​​part 322. When the first connecting part 31 is aligned and inserted into the through hole 4, the rib 323 can first come into contact with the housing 1 to bend the elastic arm 321, so as to facilitate the bending deformation of the elastic arm 321. Understandably, although the protruding snap-fit ​​portion 322 can also abut against the housing 1, causing the elastic arm 321 to undergo a certain degree of bending deformation, the addition of a rib 323 between the first connecting portion 31 and the snap-fit ​​portion 322 results in a greater bending deformation of the elastic arm 321 when the rib 323 abuts against the housing 1, thus possessing more elastic potential energy. Furthermore, when the first connecting portion 31 moves and snaps into place with the through hole 4, the rib 323 releases contact with the housing 1, and the elastic arm 321 recovers its deformation, it can push the snap-fit ​​portion 322 into the through hole 4 with a greater restoring force, thereby improving the reliability of the elastic snap-fit.

[0034] In some embodiments, such as Figure 4 , Figure 6 and Figure 8As shown, a first limiting part 41 extending towards the inner periphery of the through hole 4 is provided on the side of the through hole 4 that abuts against the first connecting part 31. A second limiting part 311 is correspondingly provided on the first connecting part 31, and the first limiting part 41 and the second limiting part 311 engage with each other. It can be understood that, to further achieve limiting abutment between the second limiting part 311 and the axial side of the through hole 4, and to further improve the limiting reliability of the second limiting part 311 and the through hole 4, a stepped first limiting part 41 can be provided around the hole on the axial side of the through hole 4. Correspondingly, a stepped second limiting part 311 can also be provided on the first connecting part 31. The first limiting part 41 can engage with the second limiting part 311 to improve limiting reliability.

[0035] In some embodiments, the connecting component 3 may include at least two spaced-apart first connecting portions 31. For example, as... Figure 3 As shown, the back of the power supply box 2 is provided with two first connecting parts 31 spaced apart. The two first connecting parts 31 can be arranged spaced apart along the length direction of the power supply box 2 or spaced apart along the width direction of the power supply box 2. Correspondingly, as shown... Figure 5 As shown, the number and position of the vias 4 are related to the first connecting parts 31, and two sets are also arranged at intervals. At least one of the first connecting parts 31 is provided with a second connecting part 32 to achieve elastic limiting and locking. In addition, there may be three, four or more first connecting parts 31 to further improve the connection reliability between the power supply box 2 and the housing 1. The number and specific position of the first connecting parts 31 are designed and selected according to the actual situation, and are not limited to the number shown in the attached figure of this embodiment. At least one of the first connecting parts 31 must be provided with a second connecting part 32. In some embodiments with multiple first connecting parts 31, each first connecting part 31 may be provided with a corresponding second connecting part 32. However, during disassembly, it is necessary to manually push out each of the multiple second connecting parts 32 to release the locking part 322 from the via 4, which is more troublesome. Therefore, it is preferable that only one of the multiple first connecting parts 31 has a second connecting part 32, which makes disassembly convenient.

[0036] Based on this, in some embodiments, such as Figure 3 As shown, the connecting component 3 may also include a support rib 33 connected to the two first connecting parts 31. The structure of the support rib 33 may include, but is not limited to, a strip rib or a cross rib. The support rib 33 may be integrally formed with the two first connecting parts 31. When the first connecting part 31, the second connecting part 32 and the through hole 4 are engaged, the support rib 33 can tightly abut against and support between the power box 2 and the housing 1, so as to further improve the support reliability between the power box 2 and the housing 1.

[0037] Based on this, in some embodiments, such as Figure 3As shown, the connecting component 3 may also include fasteners, which may be bolts. Correspondingly, a connecting seat 331 is integrally formed on the support rib 33, which may be a threaded seat. The power box 2 or the housing 1 is provided with mounting holes 11 for the fasteners to pass through, such as... Figure 6 As shown, fasteners can pass through mounting holes 11 and connect to connector 331 to further secure the power supply box 2 and housing 1, thereby further improving the connection reliability between the power supply box 2 and housing 1. For example, as... Figure 6 As shown in this embodiment, the connecting component 3 is located on the back of the power box 2, and correspondingly, the mounting hole 11 is located on the housing 1. In some other embodiments, if the connecting component 3 is located on the housing 1, the mounting hole 11 is located on the power box 2, depending on the actual needs of the design.

[0038] In some embodiments, the connection component 3 may further include a support member 34, which is disposed on the back plate or housing 1 of the power supply box 2. For example, Figure 3 As shown, one or more support members 34 may be provided, which may extend along the length or width of the power box 2 to abut against and support the power box 2 and prevent the power box 2 from shaking.

[0039] In some embodiments, the power supply box 2 can be suspended on the housing 1 via the connecting component 3, so that the power supply box 2 is a certain distance away from the ground, which can effectively prevent the power supply box 2 from being flooded and improve the waterproofness of the power supply box 2. It is understood that if water leaks inside the dishwasher, the water will flow onto the ground due to gravity. In this embodiment, suspending the power supply box 2 on the housing 1 can prevent flooding to a certain extent and improve the waterproofness of the power supply box 2.

[0040] In some embodiments, the connecting component 3 may be an integrally formed component, that is, the first connecting part 31, the second connecting part 32, the supporting rib 33 and the supporting member 34 may be directly integrally formed on the back of the power box 2, and may be produced integrally with the power box 2 by injection molding or molding, so as to improve manufacturing efficiency and simplify assembly process.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0042] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
