Description

Technical Field

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

[0002] As a household appliance for cleaning dishes, dishwashers can automatically clean dishes, freeing up your hands and saving water and being environmentally friendly. They are being accepted and recognized by more and more users.

[0003] The dishwasher has a base underneath the inner tub, which supports and fixes the inner tub. The inner tub and the base are usually directly and rigidly connected by bolts or other fasteners.

[0004] However, there is no shock absorption or cushioning design between the inner tub and the base. When the dishwasher is working or during transportation, the vibration of the inner tub will be directly transmitted to the base, and the inner tub and the base will collide hard, resulting in problems such as loud operating noise and high transportation costs. Utility Model Content

[0005] To address the aforementioned technical problems, this disclosure provides a dishwasher.

[0006] In some embodiments, a dishwasher is provided, comprising:

[0007] Inner liner, used for placing and washing tableware;

[0008] A base is disposed at the bottom of the inner liner, and the base is used to support the inner liner;

[0009] A flexible connecting component for connecting the inner liner and the base;

[0010] The elastic connection component includes:

[0011] An elastic connector includes a support portion and an elastic portion. The support portion is connected to the inner liner, and the elastic portion is connected between the base and the support portion. The elastic portion bends and extends to elastically support the inner liner.

[0012] This effectively reduces the impact between the inner liner and the base, decreases operating noise, and lowers transportation losses. The inner liner and the base are connected by an elastic connecting component. The flexible part, which extends vertically, has a large deformation. When the inner liner vibrates, the elastic part is compressed and deformed to reduce the vibration between the inner liner and the base, thus achieving an elastic connection between them.

[0013] In some embodiments, the elastic portion includes two elastic bodies, which are spaced apart between the bottom of the support portion and the base.

[0014] Therefore, the two spaced elastic bodies can reliably support the support, improving reliability and lifespan.

[0015] In some embodiments, the elastomer has an arc-shaped structure, and two elastomers are symmetrically arranged and bent toward each other or toward each other.

[0016] This makes it easier for the elastic body to undergo smooth deformation, thereby improving the cushioning effect. At the same time, the two elastic bodies are symmetrically arranged, and when the two arc-shaped elastic bodies undergo elastic deformation, the horizontal displacement of some of the elastic bodies on the elastic body is in opposite directions, reducing the tendency of the support to shift horizontally when the elastic body provides elastic force.

[0017] In some embodiments, the elastic part further includes at least one elastic body II, the elastic body II having a wave-shaped structure, the elastic body II being spaced apart between two elastic bodies I, and connected between the bottom of the support part and the base.

[0018] Therefore, the second elastomer can not only support the support part and prevent it from bending and deforming under pressure, but also further improve the buffering and energy absorption effect.

[0019] In some embodiments, the inner liner has a connecting portion, which is fixedly connected to the supporting portion.

[0020] Therefore, the elastic connector can not only achieve a reliable connection between the inner liner and the base, but also provide elastic support for the inner liner, integrating the connection function and the cushioning function into one.

[0021] In some embodiments, the resilient connection assembly further includes fasteners that pass through the connecting portion and the supporting portion to securely connect the connecting portion and the supporting portion.

[0022] Therefore, the connecting part and the support part are connected by fasteners to improve the reliability of the connection.

[0023] In some embodiments, the support portion has a threaded sleeve for screwing into the fastener.

[0024] Therefore, the fastener is threaded to the threaded cylinder on the support to achieve a detachable connection, which is convenient for disassembly and assembly at any time.

[0025] In some embodiments, the base has a receiving portion, and the elastic portion is connected within the receiving portion.

[0026] Therefore, the housing can accommodate the elastic connector, so that after the inner liner and the base are connected by the elastic connector, the overall height of the machine can still remain at the original level and there will be no significant change in height.

[0027] In some embodiments, the base includes a surrounding structure, the surrounding structure including a second surrounding plate and two first surrounding plates connected to both ends of the second surrounding plate, the first surrounding plate and the second surrounding plate enclosing the receiving portion forming a top opening, and the elastic portion being connected to the second surrounding plate.

[0028] Thus, the receiving part is formed by the first and second enclosure plates to achieve reliable support for the elastic connector.

[0029] In some embodiments, the base also has a support structure connected to the enclosure structure to support the enclosure structure.

[0030] Therefore, the supporting structure can further support the enclosure structure to prevent deformation due to insufficient support strength, thereby further improving the structural strength of the enclosure structure. Attached Figure Description

[0047] 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.

[0048] 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.

[0049] 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.

[0050] A dishwasher mainly consists of a shell, base, inner tub, dish rack, spray nozzle, water tank, and water pump. The inner tub is located inside the shell and forms a cleaning chamber. The dish rack is slidably placed in the cleaning chamber and is used to hold tableware.

[0051] The water tank is used to store cleaning water, and the water pump is used to draw water from the water tank and spray it out from the spray pipe to clean the tableware. When the tableware needs to be cleaned, the spray pipe can continuously spray water into the cleaning chamber to achieve an automatic cleaning effect.

[0052] The base is located at the bottom of the dishwasher and is used to support the entire dishwasher. The inner tub is fixedly installed on top of the base. The inner tub and the base are usually rigidly connected, that is, the inner tub is directly fixed to the base by means of clips or bolts. There is no shock absorption structure between the inner tub and the base. When the dishwasher is working, the vibration of the inner tub will be directly transmitted to the base, and may even resonate with the base, increasing the washing noise.

[0053] Furthermore, during the transportation of the dishwasher, bumps or drops during handling can cause the inner tub to vibrate. Since the inner tub and the base are rigidly connected and lack cushioning, the connection between the inner tub and the base is easily damaged when the dishwasher is dropped, resulting in high transportation costs.

[0054] In view of this, the dishwasher of this application embodiment is provided with an elastic connecting component between the inner tub and the base, which has a buffering function and can effectively reduce the vibration of the inner tub and the base, so as to solve the problems of high washing noise and high transportation cost caused by the vibration of the inner tub and the base.

[0055] 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.

[0056] This embodiment proposes a dishwasher, such as Figure 1 As shown, it includes an inner liner 1, a base 2, and an elastic connecting assembly 3. The inner liner 1 is used to place and wash tableware; specifically, a washing chamber is formed inside the inner liner 1, which can hold and wash tableware. The base 2 is located at the bottom of the inner liner 1 and is used to support and fix the inner liner 1. The inner liner 1 and the base 2 are elastically connected by the elastic connecting assembly 3.

[0057] Specifically, the elastic connection assembly 3 includes an elastic connector 31, which includes a support portion 311 and an elastic portion 312. The support portion 311 is connected to the inner liner 1. One end of the elastic portion 312 is connected to the base 2, and the other end is connected to the support portion 311. The elastic portion 312 is bent and extended as a whole to elastically support the inner liner 1.

[0058] When the inner liner 1 is installed on the base 2, the elastic part 312 will deform under the pressure of the weight of the inner liner 1. At this time, in order to recover its deformation, the elastic part 312 will generate a force opposite to the direction of the weight of the inner liner 1 to support the support part 311. Since the elastic part 312 is bent and extended, the elastic part 312 has a large deformation margin in the vertical direction, which can effectively absorb the vibration of the inner liner 1 and the base 2, and has a better elastic buffering effect.

[0059] The dishwasher of this embodiment can effectively reduce the impact between the inner tub 1 and the base 2, reduce operating noise, and reduce transportation losses. The inner tub 1 and the base 2 are connected by an elastic connecting component 3. The bent and extended elastic part 312 has a large deformation in the vertical direction when compressed. When the inner tub 1 vibrates, the elastic part 312 will be compressed and deformed to reduce the vibration between the inner tub 1 and the base 2, thus realizing the elastic connection between the inner tub 1 and the base 2.

[0060] In some embodiments, the inner liner 1 can simply rest against the support 311, that is, the outer wall surface of the inner liner 1 abuts against the support 311. The inner liner 1 and the base 2 are connected by other conventional methods. The support 311 simply supports and lifts the inner liner 1 to achieve elastic support for the inner liner 1.

[0061] Furthermore, in some embodiments, such as Figure 2 and Figure 3 As shown, the inner liner 1 may also have a connecting part 11 that can be connected to the support part 311. The connecting part 11 is fixedly disposed on the outer wall of the inner liner 1, and the elastic connector 31 is fixedly disposed on the base 2. The support part 311 is connected to the connecting part 11 of the inner liner 1, so that the elastic connector 31 can not only realize the reliable connection between the inner liner 1 and the base 2, but also effectively realize the elastic support for the inner liner 1. The connection function and the buffer function are integrated into one, the component integration is high, which helps to reduce the number of components of the whole machine, thereby reducing the production cost.

[0062] In some embodiments, of the connecting part 11 and the supporting part 311, one may be a snap-fit ​​structure, and the other may be a corresponding slot structure adapted to the snap-fit ​​structure, thereby achieving a fixed connection through a snap-fit ​​method. When the supporting part 311 is a snap-fit ​​structure or a slot structure, the elastic part 312 is located below the snap-fit ​​structure or the slot structure, with one end of the elastic part 312 connected to the snap-fit ​​structure or the slot structure and the other end connected to the base 2, so as to elastically support the supporting part 311.

[0063] Furthermore, in some embodiments, the connecting part 11 and the supporting part 311 may both be hook structures, and a fixed connection can be achieved by hooking them together.

[0064] Furthermore, in some embodiments, the connecting portion 11 and the supporting portion 311 can also be connected by fasteners 32 to ensure connection reliability. For example... Figure 3 As shown, in conjunction with reference Figure 7 The elastic connection component 3 may also include a fastener 32, the connecting part 11 is an L-shaped bent plate, the supporting part 311 is a connecting platform, and both the connecting part 11 and the supporting part 311 are provided with through holes for the fastener 32 to pass through, so that the fastener 32 can be fixed to the connecting part 11 and the supporting part 311.

[0065] Based on this, the fastener 32 can be an anchor so that the connecting part 11 and the support part 311 can be connected by a riveting method.

[0066] Based on this, fastener 32 can also be a bolt, correspondingly, such as Figure 3 As shown, the support portion 311 may also have a threaded cylinder 3111 for screwing into the fastener 32. The fastener 32 passes through the connecting portion 11 and is screwed into the threaded cylinder 3111 to realize the detachable connection between the connecting portion 11 and the support portion 311.

[0067] In some embodiments, such as Figure 3 As shown, the elastic part 312 includes two spaced elastic bodies 3121. The two elastic bodies 3121 are spaced between the bottom of the support part 311 and the base 2. Each end of the support part 311 is connected to an elastic body 3121 to improve the reliability of the support part 311, so as to keep the support part 311 in a horizontal state, so that the support part 311 is subjected to uniform force, and to prevent the pitch angle of the support part 311 from shifting during the compression process.

[0068] Understandably, given the weight of the inner liner 1, especially when it is filled with tableware, the single elastic element 3121 is highly susceptible to damage under the long-term weight of the inner liner 1, leading to localized collapse and loss of cushioning and support capabilities. Therefore, two spaced elastic elements 3121 provide reliable support for the support part 311, improving reliability and lifespan. Furthermore, the buffer cavity 310 formed by the two elastic elements 3121, the support part 311, and the base 2 ensures a cushioning effect, giving the elastic part 312 both support and cushioning capabilities, resulting in high reliability.

[0069] In some embodiments, such as Figure 3 As shown, the elastic body 3121 can be in the form of an arc shape. Compared with the straight plate structure set in the vertical direction, the arc-shaped elastic body 3121 can produce a larger deformation. The two elastic bodies 3121 bend towards each other so that the buffer cavity 310 is in the shape of an hourglass, making the buffering process more stable.

[0070] Understandably, since the two elastic bodies 3121 bend towards each other, the buffer cavity 310 is shaped like an hourglass. When the elastic body 3121 is deformed under pressure, the middle bent part of the elastic body 3121 deforms first (that is, it starts from the narrowest part of the hourglass-shaped buffer cavity 310). The deformation of the elastic body 3121 will be transmitted sequentially, stably and evenly from the middle to both ends, making the buffering process more stable.

[0071] Furthermore, the hourglass-shaped buffer cavity 310 is most prone to deformation in its narrow area, which reduces the initial force required for the deformation of the elastomer 3121 to a certain extent. The elastomer 3121 can be deformed without excessive initial force, which helps to filter out some minor vibrations of the inner liner 1 and improves the shock absorption effect.

[0072] Furthermore, the two elastic bodies 3121, which are symmetrically arranged in an arc shape, can effectively prevent the support part 311 from having a tendency to move horizontally when the two elastic bodies 3121 are deformed under pressure before and after the support part 311 is compressed, so as to ensure that the support part 311 only moves in the vertical direction.

[0073] In some embodiments, the elastomer 3121 has an arc-shaped structure, and the two elastomers 3121 can also be bent in a direction that is relatively far apart, which can also achieve the above-mentioned technical effect. The design and selection are made according to the actual situation, including but not limited to the situation shown in the accompanying drawings of this embodiment.

[0074] In some embodiments, such as Figures 4-6 As shown, at least two sets of elastic connecting components 3 are provided. The two sets of elastic connecting components 3 can be symmetrically arranged at the corners of the inner liner 1 and the base 2 to provide buffer support for both sides of the inner liner 1. In addition, the number of elastic connecting components 3 can also be set to multiple, and they can also be designed in other positions of the inner liner 1 and the base 2, depending on the actual design situation. The number and arrangement positions shown in the attached drawings of this embodiment are not limited.

[0075] In some embodiments, such as Figures 8-10 As shown, the elastic part 312 may also include at least one elastic body 3122. The elastic body 3122 may have a wave-shaped structure and extend vertically. The elastic body 3122 is spaced between two elastic bodies 3121 and connected between the support part 311 and the base 2.

[0076] It is understandable that when a single large-area buffer cavity 310 is compressed, its wall surface is prone to buckling, such as the support part 311. Since the weight of the inner liner 1 acts directly on the support part 311, the area of ​​the support part 311 is very prone to denting and bending under the weight of the inner liner 1. Over time, the support part 311 will have unreliable connection and eventually fail.

[0077] Therefore, by adding a wavy elastic body 3122 between the two elastic bodies 3121, the support part 311 can be supported and the concave deformation reduced. On the other hand, the wavy elastic body 3122 is also prone to buffer deformation, which further improves the buffering and energy absorption effect.

[0078] In addition, the number of elastomers 3122 can also be set to multiple, such as two or three, which can be selected according to actual needs. This embodiment will not list them one by one.

[0079] In some embodiments, such as Figure 5 and Figure 10 As shown, the top of the base 2 is recessed to form a receiving portion 20, which is used to receive the elastic connector 31, and the elastic portion 312 is connected inside the receiving portion 20.

[0080] Understandably, in order to minimize the overall height of the dishwasher and prevent the addition of the elastic connecting component 3 from increasing the overall height, a receiving part 20 for accommodating the elastic connecting component 31 can be specially provided on the base 2. This ensures that after the inner tub 1 and the base 2 are connected by the elastic connecting component 3, the overall height of the dishwasher can still remain at the original level and there will be no significant change in height.

[0081] In some embodiments, such as Figure 10 As shown, the base 2 has a surrounding structure 21 for enclosing the receiving portion 20. The surrounding structure 21 includes two spaced-apart first surrounding plates 211 and a second surrounding plate 212 connected to the two first surrounding plates 211. The first surrounding plates 211 and the second surrounding plates 212 enclose the receiving portion forming a top opening.

[0082] The width spacing between the two first enclosure plates 211 is slightly larger than the width of the elastic connector 31 to prevent interference with the elastic connector 31. The elastic connector 31 is mounted on the second enclosure plate 212, which is a horizontally arranged flat plate structure. The second enclosure plate 212 provides an installation platform for the elastic connector 31 to achieve reliable support for the elastic connector 31.

[0083] In addition, the receiving part 20 may also be a groove structure provided on the top of the base 2. Specifically, the receiving part 20 with a groove structure can be cut or integrally formed on the top of the base 2, including but not limited to the method shown in the attached drawings of this embodiment.

[0084] In some embodiments, such as Figure 10 As shown, the base 2 also has a support structure 22, which is connected to the enclosure structure 21 to support the enclosure structure 21.

[0085] Understandably, in order to prevent the enclosure structure 21 from being deformed under the weight of the inner liner 1 and resulting in poor support strength, a support structure 22 can be set at the bottom or around the perimeter of the enclosure structure 21 to further support the enclosure structure 21 and improve its structural strength.

[0086] Based on this, such as Figure 10As shown, the support structure 22 can be a grid-like support structure, which is composed of multiple support plates connected together, so as to form a large number of grid-like support structures on the outer periphery of the enclosure structure 21, forming several small buffer cavities, which can not only provide further support for the enclosure structure 21, but also play a further buffering role to a certain extent.

[0087] In addition, the support structure 22 can also adopt other structural forms, such as conventional reinforcing ribs. These reinforcing ribs are inclined and one end can be connected to the bottom surface of the second enclosure 212, while the other end can be connected to the wall surface of the base 2, so that the reinforcing ribs, the second enclosure 212, and the base 2 form a stable triangular support.

[0088] In some embodiments, the elastic connector 31, the surrounding plate structure 21, and the support structure 22 can be integrally formed with the base 2 to simplify subsequent connection processes and thereby reduce costs.

[0089] 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.

[0090] 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.
