A dishwasher

Abstract

The application discloses a dishwasher, and belongs to the technical field of washing equipment, and aims to solve the technical problem that the pulling-out degree of a lower basket is limited when a related dishwasher is embedded and installed. The dishwasher comprises a box body, a door body, a lower basket and a limiting structure; the limiting structure is connected to the lower basket, and the limiting structure has a limiting state and an unfolded state; when the dishwasher is independently installed, the limiting structure is adjusted to the limiting state. When the door body is in an open state, the lower basket is pulled forward, and the limiting structure is used for stopping at the rear end of the door body, so that the possibility that the dishwasher is tilted due to the excessive pulling-out of the lower basket and the forward movement of the gravity center of the dishwasher when the dishwasher is fully loaded with tableware is reduced. When the dishwasher is embedded and installed, the limiting structure is adjusted to the unfolded state. When the door body is in the open state, the limiting structure is disengaged from the door body, the pulling-out degree of the lower basket is improved, the lower basket is less shielded by the box body, and the tableware is conveniently placed in the lower basket or taken out from the lower basket.

Description

Technical Field

[0001] This application relates to the field of washing equipment technology, and more particularly to a dishwasher. Background Technology

[0002] A dishwasher is a household appliance used to automatically clean dishes, cookware, and tableware. It removes dirt and food residue from dishes by spraying high-pressure water through spray arms.

[0003] In related technologies, the dishwasher's lower rack is equipped with a downward-extending limit bar. The limit bar can abut against the rear end of the door when the lower rack is pulled out, so as to limit the pull-out stroke of the lower rack relative to the inner tub when the dishwasher is installed independently, and prevent the lower rack from being pulled out excessively when fully loaded with dishes, causing the dishwasher's center of gravity to shift forward and thus causing the whole machine to tip over.

[0004] However, when dishwashers are installed as built-in appliances, the limiting rod restricts the extent to which the lower dish rack can be pulled out, reducing the convenience for users to load and unload dishes. Utility Model Content

[0005] This application provides a dishwasher that solves the technical problem that the pull-out extent of the lower basket is limited when the dishwasher is embedded in the wall.

[0006] This application provides a dishwasher, including:

[0007] The enclosure is designed with a washing chamber.

[0008] The door, whose bottom is rotatably connected to the cabinet, allows the washing chamber to be opened or closed;

[0009] The lower dish rack is retractable and installed inside the washing chamber;

[0010] The limiting structure includes:

[0011] A fastener is connected to the lower basket, and the fastener has a first snap-fit ​​part.

[0012] The movable part is rotatably connected to the fixed part, and the movable part has a second snap-fit ​​part.

[0013] The limiting structure has a limiting state and an unfolded state;

[0014] When the limiting structure is in the limiting state, the second locking part engages with the first locking part, and the movable part is used to stop at the rear end of the door when the door is opened;

[0015] When the limiting structure is in the unfolded state, the second locking part is separated from the first locking part, and the movable part is used to be spaced apart from the door body along the height direction of the box body when the door body is opened.

[0016] In this embodiment of the dishwasher, when installed independently, the movable component rotates relative to the fixed component until it is in a limited position by the limiting structure. When the door is open, part of the movable component is opposite to the rear end of the door along the depth direction of the cabinet. When the dish rack is pulled forward, the movable component stops at the rear end of the door, reducing the possibility of the dishwasher's center of gravity shifting forward and thus tipping over when the dish rack is fully loaded.

[0017] When the dishwasher is installed as a built-in unit, the movable component rotates relative to the fixed component until it is in the extended position at the limiting structure. When the door is open, the movable component is spaced apart from the door along the height of the dishwasher, with the movable component positioned above the door. When the lower dish rack is pulled forward, the movable component does not contact or block the door. The movable component does not restrict the extent to which the lower dish rack can be pulled out, increasing the extent to which the lower dish rack can be pulled forward and reducing the obstruction of the space above the lower dish rack by the dishwasher, making it easier to place or remove tableware from the lower dish rack.

[0018] In some embodiments of this application, the fastener is configured with a pivot extending along the width direction of the housing;

[0019] The movable component has a connected first snap-fit ​​channel and a first channel opening;

[0020] The rotating shaft is rotatably engaged in the first engaging channel via the first channel opening.

[0021] With this configuration, the rotating shaft is rotatably engaged in the first engaging channel via the first channel opening, so that the moving part can rotate around the rotating shaft.

[0022] In some embodiments of this application, the first snap-fit ​​portion includes a snap-fit ​​ring, and the snap-fit ​​ring surrounds a snap-fit ​​hole;

[0023] The second latching part includes an elastic arm and a locking part; the locking part is connected to the end of the elastic arm;

[0024] When the limiting structure is in the limiting state, the elastic arm passes through the card hole, and the locking part stops at the card ring.

[0025] With this configuration, the locking part can prevent the moving part from rotating backward away from the fixed part, making it difficult for the moving part to rotate backward away from the fixed part when it stops at the rear end of the door, thereby keeping the limiting structure in the limiting state.

[0026] In some embodiments of this application, the movable component is constructed with a first clearance channel and a first clearance opening that are connected to each other;

[0027] When the limiting structure is in the limiting state, the first clearance opening is located at the top of the first clearance channel, and the part of the snap ring is accommodated in the first clearance channel through the first clearance opening.

[0028] With this configuration, the side wall of the first clearance channel away from the first clearance opening can be stopped at the bottom of the retaining ring to prevent the moving part from rotating forward toward the fixed part, making it easier for the limiting structure to remain in the limiting state.

[0029] In some embodiments of this application, the bottom of the lower basket has a longitudinal support rod extending along the depth direction of the box;

[0030] The fastener has a connected second snap-fit ​​channel and a second channel opening;

[0031] The longitudinal support rod is engaged in the second engagement channel via the second channel opening.

[0032] This design, by attaching the fastener to the longitudinal support rod, improves the ease of connecting and disassembling the fastener to the longitudinal support rod.

[0033] In some embodiments of this application, the movable component is constructed with a connected second clearance channel and a second clearance opening;

[0034] When the limiting structure is in the limiting state, the second clearance opening is located at the top of the second clearance channel, and part of the longitudinal support rod is accommodated in the second clearance channel through the second clearance opening.

[0035] With this configuration, the second clearance channel can avoid the longitudinal support rod, reducing the possibility of interference between the moving part and the longitudinal support rod during the rotation to the limit state.

[0036] In some embodiments of this application, the movable component is constructed with a connected third clearance channel and a third clearance opening;

[0037] When the limiting structure is in the deployed state, the third clearance opening is located at the top of the third clearance channel, and part of the longitudinal support rod is accommodated in the third clearance channel through the third clearance opening.

[0038] With this configuration, the third clearance channel can avoid the longitudinal support rod, reducing the possibility of interference between the moving part and the longitudinal support rod during the rotation to the unfolded state.

[0039] In some embodiments of this application, the bottom of the lower basket has a first lateral support rod extending along the width direction of the box body;

[0040] The fastener has a connected third snap-fit ​​channel and a third channel opening;

[0041] The first transverse support rod is engaged in the third engagement channel via the third channel opening.

[0042] This design, by attaching the fastener to the first transverse support rod, improves the ease of connecting and disassembling the fastener to the first transverse support rod.

[0043] In some embodiments of this application, the bottom of the lower basket has a second lateral support rod extending along the width direction of the box body;

[0044] The movable part has a connected fourth locking channel and a fourth channel opening;

[0045] When the limiting structure is in the unfolded state, the fourth channel opening is located at the top of the fourth snap-fit ​​channel, and the second transverse support rod is snapped into the fourth snap-fit ​​channel through the fourth channel opening.

[0046] This configuration allows the movable part to be snapped into the second transverse support rod, so that the movable part can remain in the extended state and is difficult to rotate to the limit state when no external force is applied.

[0047] In some embodiments of this application, the dishwasher further includes a divider, which includes a connecting rod and a plurality of dividers; the plurality of dividers are spaced apart from the connecting rod.

[0048] The fastener has a connected fifth snap-fit ​​channel and a fifth channel opening;

[0049] There are multiple limiting structures. The two ends of the connecting rod are connected to one limiting structure respectively, and the end of the connecting rod is locked in the fifth locking channel through the fifth channel opening.

[0050] With this configuration, the divider is connected to the lower basket via two limiting structures. Attached Figure Description

[0101] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0102] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0103] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0104] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0105] To address the issue in related technologies where the lower dish rack cannot be fully extended during built-in installation of dishwashers, this application provides a dishwasher with a limiting structure on the lower dish rack. The limiting structure includes a fixed member connected to the lower dish rack and a movable member rotatably connected to the fixed member. When the dishwasher is installed independently, rotating the movable member puts the limiting structure in a limited state. When the door is opened, pulling the lower dish rack forward causes the movable member to stop at the rear end of the door, preventing the dishwasher from tipping over when the lower dish rack is fully loaded. When the dishwasher is built-in, rotating the movable member puts the limiting structure in an extended state. When the door is opened, pulling the lower dish rack forward causes the movable member to move above the door without stopping, increasing the length of the lower dish rack that can be pulled out of the washing chamber and improving the convenience for users to remove and place dishes from the lower dish rack.

[0106] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0107] refer to Figure 1 The dishwasher provided in this application embodiment includes a cabinet, a door 20, and a dish rack assembly 30.

[0108] refer to Figure 1 A washing chamber 110 is formed inside the box. An operation port 120 is provided on the front side of the washing chamber 110, and the operation port 120 is connected to the washing chamber 110.

[0109] It should be noted that, in the embodiments of this application, the directional term "front" refers to the side of the dishwasher facing the user during normal use, that is... Figure 1 The positive direction of the depth Y-axis of the middle cabinet is "front". The directional term "rear" refers to the side opposite to "front", that is, the side of the dishwasher that faces away from the user when it is in normal use. Figure 1 The negative direction of the depth direction Y of the middle box is "back".

[0110] refer to Figure 1 The enclosure may include a shell and an inner liner 10, with the inner liner 10 disposed inside the shell to form the appearance of the enclosure. The inner liner 10 has a washing chamber 110 internally.

[0111] The bottom of the door 20 is rotatably connected to the housing, and the door 20 is used to open or close the operating port 120.

[0112] The door 20 has an open state and a closed state.

[0113] When the door 20 is in the closed state, the operating port 120 is closed. When opening the door 20 from the closed state, a forward and downward external force is applied to the top of the door 20, causing the top of the door 20 to rotate forward and downward relative to the bottom of the door 20 until the door 20 is approximately horizontal, at which point the door 20 is in the open state (e.g., ...). Figure 1 (As shown).

[0114] The dish rack assembly 30 is disposed inside the washing chamber 110 and is used to place tableware or kitchen utensils, etc.

[0115] The dish rack assembly 30 is retractably disposed within the washing chamber 110 via the operating port 120. The direction in which the dish rack assembly 30 is pulled out relative to the cabinet can be approximately along the depth direction Y of the cabinet. After at least a portion of the dish rack assembly 30 is pulled out of the washing chamber 110, the obstruction of the cabinet to the space above the dish rack assembly 30 can be reduced, making it easier to place or remove tableware from the dish rack assembly 30.

[0116] In some possible implementations of the embodiments of this application, reference is made to Figure 1 The dish basket assembly 30 may include a dish basket and casters 320. The casters 320 are disposed on both sides of the dish basket along the width direction X of the container body, and the axis of the casters 320 extends approximately along the width direction X of the container body. The casters 320 are rotatably disposed within the container body. During the rotatability of the casters 320 relative to the container body, they drive the dish basket to move along the depth direction Y of the container body.

[0117] In some other possible implementations of the embodiments of this application, the basket assembly 30 can be slidably disposed on the box body via a slide rail structure, so that the basket assembly 30 can move relative to the box body along the depth direction Y of the box body.

[0118] In some possible implementations of the embodiments of this application, the bowl basket assembly 30 may include a bowl basket, and the number of bowl baskets may be one or more.

[0119] In implementations where there are two or more dish racks, multiple dish racks can be arranged at intervals along the height direction Z within the washing chamber 110. This improves the space utilization within the washing chamber 110 and reduces overlap and obstruction between tableware, thereby reducing cleaning dead corners and improving the cleaning effect on fragile tableware.

[0120] refer to Figure 1 The dish rack may include a lower dish rack 310, which is located at the bottom of the washing chamber 110.

[0121] The following is for reference Figure 2 The structure of the lower bowl basket 310 is described.

[0122] The bottom of the lower basket 310 may have multiple horizontal support rods 313, which may extend along the width direction X of the basket. The multiple horizontal support rods 313 are arranged at intervals along the depth direction Y of the basket.

[0123] At least some of the horizontal support rods 313 can be bent upwards at both ends to form a horizontal bending rod 314. The horizontal bending rod 314 can block the outer perimeter of the tableware and reduce the possibility of the tableware falling off the edge of the lower bowl basket 310.

[0124] The bottom of the lower basket 310 may have multiple longitudinal support rods 311, which may extend along the depth direction Y of the basket. The multiple longitudinal support rods 311 are arranged at intervals along the width direction X of the basket. The longitudinal support rods 311 are connected to multiple transverse support rods 313.

[0125] In some embodiments, the longitudinal support rod 311 may be connected to the bottom of the transverse support rod 313 (e.g., Figure 2 (As shown).

[0126] In other embodiments, the longitudinal support rod 311 may be connected to the top of the transverse support rod 313.

[0127] At least some of the longitudinal support rods 311 can be bent upwards at both ends to form longitudinal bending rods 312. The longitudinal bending rods 312 can block the outer perimeter of the tableware and reduce the possibility of the tableware falling off the edge of the lower bowl basket 310.

[0128] The lower basket 310 may have multiple transverse reinforcing bars 317, which extend approximately along the width direction X of the basket. The transverse reinforcing bars 317 are connected to multiple longitudinal bending bars 312 to improve the structural stability of the longitudinal bending bars 312.

[0129] The lower basket 310 may have multiple longitudinal reinforcing bars 318, which extend approximately along the depth direction Y of the box. The longitudinal reinforcing bars 318 are connected to multiple transverse bending bars 314 to improve the structural stability of the transverse bending bars 314.

[0130] The dishwasher in this embodiment can be installed independently or embedded in the wall.

[0131] Freestanding dishwasher installation refers to placing the dishwasher as a standalone appliance in a suitable location in the kitchen (such as on the floor or countertop), without any built-in or integrated fixed connection to cabinets, sinks, or other appliances. It functions normally simply by connecting to a power source and drain pipe. This installation method offers high flexibility and has relatively lower requirements for kitchen space and layout.

[0132] Built-in dishwasher installation refers to embedding the dishwasher entirely into the kitchen cabinetry, creating a unified look and layout with the cabinets, with only the control panel or flush with the cabinet doors visible. This installation method prioritizes aesthetics and space utilization, making it a common choice in modern kitchen renovations.

[0133] In a stand-alone dishwasher, if the lower rack 310 is pulled out excessively when fully loaded with dishes, it can cause the dishwasher's center of gravity to shift forward, leading to the entire dishwasher tipping forward.

[0134] Built-in dishwashers, because they are embedded in the cabinet, have a small gap between the top of the dishwasher and the cabinet, generally less than 10mm. Even when the lower basket 310 is fully extended and loaded with dishes, the cabinet's support prevents the dishwasher from tipping forward due to the increased center of gravity. The further the lower basket 310 is extended, the less the cabinet obstructs the space above it, making it easier to place or remove dishes from the lower basket.

[0135] To prevent the lower dish rack 310 from being excessively pulled out when the dishwasher in this embodiment is installed independently, and to increase the degree of pull-out when it is installed in a recessed configuration, the dishwasher in this embodiment has a limiting structure 40 on the lower dish rack 310, as shown in the reference. Figure 2 The limiting structure 40 has a limiting state and an unfolded state.

[0136] refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 When the dishwasher is installed independently, the limiting structure 40 is adjusted to the limiting state. When the door 20 is in the open state, the dish rack 310 is pulled forward, and the limiting structure 40 is used to stop at the rear end 201 of the door, reducing the possibility that the dishwasher's center of gravity will shift forward and thus cause the whole machine to tip over when the dish rack 310 is pulled out excessively when the dishwasher is full of dishes.

[0137] refer to Figures 6-9 When the dishwasher is installed as a built-in unit, the limiting structure 40 is adjusted to the unfolded state. When the door 20 is in the open state, the limiting structure 40 and the door 20 are spaced apart by a distance D along the height direction Z of the cabinet, and the limiting structure 40 is located above the door 20. The limiting structure 40 and the door 20 are no longer blocking each other, which increases the extent to which the lower dish rack 310 can be pulled forward and reduces the obstruction of the cabinet to the space above the lower dish rack 310, making it easier to place or remove tableware from the lower dish rack 310.

[0138] refer to Figure 3 , Figure 10 and Figure 11 The limiting structure 40 in this embodiment may include a fixing member 410, which is connected to the lower basket 310.

[0139] In some possible implementations of the embodiments of this application, reference is made to Figure 10 and Figure 11 The fastener 410 may be configured with a second snap-fit ​​channel 414 and a second channel opening 415. The second snap-fit ​​channel 414 may extend along the depth direction Y of the housing, and the second channel opening 415 is connected to the second snap-fit ​​channel 414.

[0140] refer to Figure 12 and Figure 13 The longitudinal support rod 311 of the lower bowl basket 310 is engaged in the second engagement channel 414 via the second channel opening 415, so as to engage the fixing member 410 with the longitudinal support rod 311, thereby improving the convenience of connecting and disassembling the fixing member 410 and the longitudinal support rod 311.

[0141] In some possible implementations of the embodiments of this application, reference is made to Figure 10 and Figure 11 The fastener 410 may be configured with a third snap-fit ​​channel 416 and a third channel opening 417. The third snap-fit ​​channel 416 may extend along the width direction X of the housing, and the third channel opening 417 is connected to the third snap-fit ​​channel 416.

[0142] refer to Figure 2 The lower bowl basket 310 has multiple horizontal support rods 313 at its bottom, including a first horizontal support rod 315. (See reference) Figure 13 The first transverse support rod 315 is engaged in the third engagement channel 416 via the third channel opening 417, so as to engage the fastener 410 with the first transverse support rod 315, thereby improving the convenience of connecting and disassembling the fastener 410 and the first transverse support rod 315.

[0143] The following embodiment describes the connection structure between the limiting structure 40 and the lower basket 310, taking the connection of the longitudinal support rod 311 to the bottom of the transverse support rod 313 as an example.

[0144] In some possible implementations of the embodiments of this application, reference is made to Figure 13The first transverse support rod 315 can intersect and connect with the longitudinal support rod 311. The second locking channel 414 is located below the third locking channel 416. The first transverse support rod 315 is locked into the third locking channel 416 via the third channel opening 417, and the longitudinal support rod 311 is locked into the second locking channel 414 via the second channel opening 415, so that the fixing member 410 is simultaneously locked into the first transverse support rod 315 and the longitudinal support rod 311, which improves the connection strength between the fixing member 410 and the lower basket 310, making it less likely for the fixing member 410 to fall off the lower basket 310.

[0145] In some embodiments, reference Figure 13 The third locking channel 416 and the second locking channel 414 can be located at the bottom of the fixing member 410, respectively. The second channel opening 415 can be located at the bottom of the second locking channel 414. The third channel opening 417 can be located at the bottom of the third locking channel 416. The fixing member 410 moves from top to bottom relative to the lower basket 310 and is simultaneously locked in the second locking channel 414 and the third locking channel 416.

[0146] The third snap-fit ​​channel 416 and the second snap-fit ​​channel 414 are both located at the bottom of the fixing member 410, making it difficult for users to observe the third snap-fit ​​channel 416 and the second snap-fit ​​channel 414, thus improving the decorative effect of the dishwasher.

[0147] It is understood that in some other embodiments, the third engaging channel 416 and the second engaging channel 414 may be located at the top of the fixing member 410, respectively. The second channel opening 415 may be located at the top of the second engaging channel 414. The third channel opening 417 may be located at the top of the third engaging channel 416. The fixing member 410 moves upward relative to the lower basket 310 and is simultaneously engaged within the second engaging channel 414 and the third engaging channel 416.

[0148] refer to Figure 3 , Figure 10 and Figure 14 The limiting structure 40 in this embodiment may further include a movable member 420, which is rotatably connected to the fixed member 410, so that the limiting structure 40 is in a limited state (see reference). Figure 10 ) and unfolded state (reference) Figure 15 Switch between )

[0149] In some possible implementations of the embodiments of this application, reference is made to Figure 11 The fastener 410 may be configured with a pivot 412 extending along the width direction X of the housing.

[0150] refer to Figure 14 The movable component 420 can be constructed with a first connecting channel 424 and a first channel port 425 that are connected.

[0151] refer to Figure 15 The rotating shaft 412 is rotatably engaged in the first engaging channel 424 via the first channel opening 425, so that the movable part 420 can rotate around the rotating shaft 412.

[0152] In some other possible implementations of this application, the movable member 420 may be configured with a rotating shaft extending along the width direction X of the housing. The fixed member 410 may be configured with a first engaging channel and a first channel opening that are connected. The rotating shaft is rotatably engaged in the first engaging channel via the first channel opening, so that the movable member 420 can rotate about the axis of the rotating shaft relative to the fixed member 410.

[0153] In some possible implementations of the embodiments of this application, reference is made to Figure 11 and Figure 15 The fastener 410 may be configured with a first snap-fit ​​portion 411. (See reference) Figure 14 and Figure 15 The movable part 420 can be configured with a second snap-fit ​​part 421. (See reference) Figure 16 When the limiting structure 40 is in the limiting state, the second locking part 421 engages with the first locking part 411 to prevent the movable part 420 from continuing to rotate relative to the fixed part 410, thereby keeping the limiting structure 40 in the limiting state.

[0154] Among some possible implementations, refer to Figure 11 The first snap-fit ​​part 411 can be a snap-fit ​​ring, and the snap-fit ​​ring surrounds a snap-fit ​​hole 413.

[0155] refer to Figure 14 The second latching part 421 includes an elastic arm 422 and a locking part 423. The locking part 423 is connected to the end of the elastic arm 422.

[0156] refer to Figure 15 When the limiting structure 40 is in the unfolded state, the elastic arm 422 and the locking part 423 are both separated from the snap ring.

[0157] When the limiting structure 40 is in the unfolded state, rotating the movable member 420 causes the locking part 423 to gradually approach the locking ring until the locking part 423 stops at the locking ring via the locking hole 413, and the elastic arm 422 passes through the locking hole 413. At this point, the locking part 423 can prevent the movable member 420 from rotating backward away from the fixed member 410, making it difficult for the movable part to rotate backward away from the fixed member 410 when it stops at the rear end 201 of the door body. This keeps the limiting structure 40 in the limited state (see reference). Figure 16 ).

[0158] In some embodiments, reference Figure 15 The movable component 420 may be constructed with a first clearance passage 426 and a first clearance opening 427 that are connected.

[0159] refer to Figure 16 When the limiting structure 40 is in the limiting state, the first clearance opening 427 is located at the top of the first clearance channel 426. The portion of the snap ring is accommodated in the first clearance channel 426 through the first clearance opening 427. The side wall of the first clearance channel 426 away from the first clearance opening 427 can stop the bottom of the snap ring to prevent the moving part 420 from rotating forward toward the fixed part 410, making it easier for the limiting structure 40 to remain in the limiting state.

[0160] In some other possible implementations, the first latching portion 411 may include a resilient arm and a locking portion, with the locking portion connected to the end of the resilient arm. The second latching portion 421 may be a latching ring, which encloses a latching hole.

[0161] When the limiting structure 40 is in the unfolded state, both the elastic arm and the locking part are separated from the snap ring.

[0162] When the limiting structure 40 is in the unfolded state, the movable part 420 is rotated, and the locking ring gradually approaches the fixed part 410 until the locking part stops at the locking ring through the locking hole, and the elastic arm passes through the locking hole. At this time, the movable part 420 can hardly continue to rotate relative to the fixed part 410, thereby keeping the limiting structure 40 in the limiting state.

[0163] It is understandable that the first locking part 411 and the second locking part 421 can also be locked in other ways, as long as the moving part 420 is prevented from continuing to rotate relative to the fixed part 410 when the limiting structure 40 is in the limiting state.

[0164] In this embodiment of the dishwasher, when the dishwasher is installed independently, the movable part 420 rotates relative to the fixed part 410 until the limiting structure 40 is in a limited state (see reference). Figure 10 and Figure 16 When the door 20 is in the open position, along the depth direction Y of the box, part of the movable part 420 is opposite to the rear end 201 of the door. Pulling the basket 310 forward, the movable part 420 stops at the rear end 201 of the door (reference). Figure 3 and Figure 5 This reduces the possibility of the dishwasher tipping over due to excessive pulling out of the lower basket 310 when fully loaded with dishes, which could cause the dishwasher's center of gravity to shift forward.

[0165] During dishwasher installation, the movable part 420 rotates relative to the fixed part 410 until the limiting structure 40 is in the unfolded state (see reference). Figure 15 When the door 20 is in the open state, along the height direction Z of the housing, the movable part 420 is spaced D from the door 20, and the movable part 420 is located above the door 20 (see reference). Figure 7 and Figure 9When the lower bowl basket 310 is pulled forward, the movable part 420 does not contact or block the door 20. The movable part 420 does not restrict the extent to which the lower bowl basket 310 can be pulled out, thereby increasing the extent to which the lower bowl basket 310 can be pulled forward and reducing the obstruction of the space above the lower bowl basket 310 by the cabinet, making it easier to place tableware into or take tableware out of the lower bowl basket 310.

[0166] In some possible implementations of the embodiments of this application, reference is made to Figure 14 The movable component 420 can be configured with a connected second clearance channel 428 and a second clearance opening 429.

[0167] When the limiting structure 40 is in the limiting state, the second clearance opening 429 is located at the top of the second clearance channel 428. (Reference) Figure 13 , Figure 17 and Figure 18 A portion of the longitudinal support rod 311 is housed within the second clearance channel 428 via the second clearance opening 429. The second clearance channel 428 can avoid the longitudinal support rod 311, reducing the possibility of interference between the moving part 420 and the longitudinal support rod 311 during the rotation to the limit state.

[0168] In some possible implementations of the embodiments of this application, reference is made to Figure 14 The movable part 420 is constructed with a connected third clearance channel 4210 and a third clearance opening 4211.

[0169] refer to Figure 19 and Figure 20 When the limiting structure 40 is in the deployed state, the third clearance opening 4211 is located at the top of the third clearance channel 4210, and part of the longitudinal support rod 311 is accommodated within the third clearance channel 4210 via the third clearance opening 4211. The third clearance channel 4210 can avoid the longitudinal support rod 311, reducing the possibility of interference between the moving part 420 and the longitudinal support rod 311 during the rotation to the deployed state.

[0170] In some possible implementations of the embodiments of this application, reference is made to Figure 2 and Figure 20 The multiple horizontal support rods 313 at the bottom of the lower basket 310 may include a second horizontal support rod 316. The second horizontal support rod 316 and the first horizontal support rod 315 are spaced apart along the depth direction Y of the box.

[0171] refer to Figure 14 The movable component 420 can be configured with a connected fourth snap-fit ​​channel 4212 and a fourth channel port 4213.

[0172] refer to Figure 20When the limiting structure 40 is in the unfolded state, the fourth channel opening 4213 is located at the top of the fourth snap-fit ​​channel 4212. The second transverse support rod 316 is snapped into the fourth snap-fit ​​channel 4212 via the fourth channel opening 4213 to snap the movable part 420 into the second transverse support rod 316, so that the movable part 420 can be kept in the unfolded state and the movable part 420 is difficult to rotate to the limiting state when it is not subjected to external force.

[0173] The number of limit structures 40 can be one, two or more, etc.

[0174] In the implementation of multiple limiting structures 40, the multiple limiting structures 40 can be arranged at intervals along the width direction X of the box body on the lower basket 310. When the limiting structure 40 is in the limiting state, pulling the lower basket 310 forward causes multiple moving parts 420 to simultaneously stop at the rear end 201 of the door body, improving the reliability of the stopping cooperation between the limiting structure 40 and the door body 20. Furthermore, the rearward pressure of the door body 20 on the basket assembly 30 is distributed across multiple moving parts 420, reducing the pressure borne by a single moving part 420 and lowering the possibility of collision damage to the moving parts 420.

[0175] In some possible implementations of the embodiments of this application, reference is made to Figure 2 and Figure 21 The dish basket assembly 30 may also include a divider 330, which may include a connecting rod 331 and a plurality of divider rods 332. The plurality of divider rods 332 are spaced apart from the connecting rod 331 to form a plurality of locking gaps 333. The locking gaps 333 can be used to place tilted plates, etc.

[0176] The number of limit structures 40 can be two or more. (Reference) Figure 2 and Figure 21 The two limiting structures 40 are respectively connected to the two ends of the connecting rod 331.

[0177] refer to Figure 22 The fastener 410 may be configured with a connected fifth snap-fit ​​channel 418 and a fifth channel opening 419.

[0178] Both ends of the connecting rod 331 are connected to a limiting structure 40 respectively. The end of the connecting rod 331 is locked in the fifth locking channel 418 via the fifth channel opening 419, so that the separator 330 is connected to the lower bowl basket 310 through the two limiting structures 40.

[0179] In some embodiments, reference Figure 22 The connecting rod 331 can extend along the width direction X of the box, and the end of the connecting rod 331 can be bent backward to form a connecting bent rod 334.

[0180] The fifth channel opening 419 can be located at the front of the fifth snap-fit ​​channel 418. The connecting bending rod 334 can be snapped into the fifth snap-fit ​​channel 418 via the fifth channel opening 419 so that the separator 330 can be connected to the lower bowl basket 310 through the two limiting structures 40.
