Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and particularly to a dishwasher. Background Art

[0002] A dishwasher is a device used to automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. It can be divided into two categories: box type and conveyor type according to its structure. It reduces the labor intensity of the cooking staff in restaurants, hotels, and canteens of government agencies and improves work efficiency. When the dishwasher cleans the tableware, the tableware needs to be placed on the shelf inside the dishwasher, and the shelf is used to stably support the tableware, so that the dishwasher can clean the tableware.

[0003] In the related art, there is an inner container inside the dishwasher, a cleaning cavity is formed inside the inner container, and a plurality of sliding rails are connected to the side wall of the cleaning cavity at intervals in the vertical direction. A pulley is provided on the shelf, and the pulley is slidably connected to the sliding rail. By sliding the pulley on the sliding rail, the shelf can be pulled out of the cleaning cavity along the depth direction of the dishwasher, so that the tableware can be placed on the shelf, and then the tableware can be sent into the cleaning cavity for cleaning. When the sizes of the tableware are different, by connecting the pulley to different sliding rails, the up and down positions of the shelf can be adjusted, so that tableware of different sizes can be placed on the shelf, and then tableware of different sizes can be cleaned.

[0004] In the above-mentioned dishwasher, when adjusting the up and down position of the shelf, the shelf needs to be pulled out of the cleaning cavity, and the pulley needs to be disassembled from the sliding rail, and then the sliding rail and the pulley at different heights need to be reselected for assembly, which will make the adjustment process of the shelf more cumbersome, resulting in very inconvenient adjustment of the shelf. Summary of the Invention

[0005] An embodiment of the present invention provides a dishwasher, which solves the problem that it is inconvenient to adjust the position of the shelf in the height direction of the dishwasher in the prior art.

[0006] To achieve the above object, the embodiment of the present invention adopts the following technical solutions:

[0007] According to a first aspect of the present application, a dishwasher is provided, which includes an inner container, a bracket, a shelf, a first limiting member, and a second limiting member. A cleaning cavity is formed in the inner container; the bracket is arranged in the cleaning cavity and connected to the inner container; the shelf is arranged in the cleaning cavity and connected to the bracket. Along the height direction of the dishwasher, the shelf can move relative to the bracket between a first position and a second position; a first limiting portion is formed on the shelf; the first limiting member is connected to the bracket; the second limiting member is located above the first limiting member and rotatably connected to the bracket. The direction of the rotation axis of the second limiting member is consistent with the height direction of the dishwasher; when the shelf is in the first position, the first limiting portion is located above the first limiting member and abuts against the first limiting member; when the shelf is in the second position, a part of the second limiting member rotates to below the first limiting portion and abuts against the first limiting portion.

[0008] For the dishwasher provided by the present application, a cleaning cavity is formed in the inner container. The bracket is arranged in the cleaning cavity and connected to the inner container. The shelf is arranged in the cleaning cavity and connected to the bracket. Thus, tableware can be placed on the shelf for cleaning. Along the height direction of the dishwasher, the shelf can move relative to the bracket between a first position and a second position. When tableware with a relatively large height needs to be placed on the shelf, the second limiting member rotates around its rotation axis to avoid the first limiting portion, and then the shelf is pushed vertically to move the shelf to the first position. At this time, the first limiting member is below the first limiting portion and abuts against the first limiting member, so that the first limiting member supports the shelf. At this time, there is a relatively large space above the shelf, which is convenient for accommodating tableware with a relatively large height.

[0009] When tableware with a relatively large height does not need to be placed on the shelf, the second limiting member rotates around the rotation axis to avoid the first limiting portion, and then the shelf is pulled vertically to move the shelf to the second position. Then the second limiting member is rotated in the reverse direction so that a part of the second limiting member rotates to below the first limiting portion and abuts against the first limiting member, so that the second limiting member supports the shelf at this position. At this time, the spaces above and below the shelf are both relatively appropriate, which is convenient for placing tableware above and below the shelf.

[0010] In the above manner, during the process of adjusting the shelf, only the second limiting member needs to be rotated to avoid the first limiting portion, and it is not necessary to pull the shelf out of the cleaning cavity, nor to disassemble the shelf and then reinstall it at a new position. Therefore, the adjustment process of the shelf can be simplified, and the adjustment of the shelf can be made more convenient.

[0011] In some embodiments, a limiting hole is formed on the bracket. The limiting hole is located above the first limiting member, and the axial direction of the limiting hole is perpendicular to the rotation axis of the second limiting member. The second limiting member includes a rotating plate and a limiting boss. The rotating plate is rotatably connected to the bracket. The limiting boss is connected to the rotating plate so that the rotating plate drives the limiting boss to pass through or withdraw from the limiting hole. During the movement of the shelf from the first position to the second position, the limiting boss withdraws from the limiting hole to avoid the first limiting portion. When the shelf moves to the second position, the limiting boss passes through the limiting hole so that the limiting boss is located below the first limiting portion and abuts against the first limiting portion. In this way, after rotating the limiting plate to drive the limiting boss into the limiting hole, the side wall of the bracket close to the rotating plate can abut against one end of the rotating plate close to the limiting boss, thereby restricting the movement of the rotating plate in the axial direction of the limiting hole, and further restricting the movement of the boss in the axial direction of the limiting hole, so as to avoid excessive rotation amplitude of the limiting boss, resulting in the inability of the limiting boss to support the first limiting portion, or resulting in a small contact area between the limiting boss and the first limiting portion, which affects the support effect on the first limiting portion. Moreover, after the limiting boss passes through the limiting hole, the limiting hole can restrict the movement of the limiting boss in the direction perpendicular to the axis of the limiting hole, thereby making the limiting boss more stable in the limiting hole, and further making the support of the limiting boss on the first limiting portion more stable.

[0012] In some embodiments, the dishwasher further comprises an adjustment assembly, the adjustment assembly comprising a first adjustment member and an adjustment handle, the first adjustment member being connected to the rack; the adjustment handle being rotatably connected to the first adjustment member, and a first extrusion portion being formed on the adjustment handle; during the movement of the rack between the first position and the second position, the first extrusion portion can contact the second stopper and push the second stopper to rotate so that the second stopper avoids the first stopper, so that when the rack needs to move from the first position to the second position, people can directly pull the first adjustment member in the direction from the first position to the second position, thereby driving the rack to move, during which the first adjustment member can also drive the adjustment handle to move accordingly, thereby enabling the first extrusion portion on the adjustment handle to contact the second stopper and push the second stopper to rotate so that the second stopper avoids the first stopper, thereby enabling the rack to smoothly reach the second position. After the rack moves to the second position, the first extrusion portion moves to the top of the second stopper and no longer pushes the second stopper to rotate, at which time, a part of the second stopper, i.e., the stopper boss, rotates to the bottom of the first stopper to support the first stopper. When the shelf needs to be moved from the second position to the first position, the adjusting handle is rotated so that the first extruding portion pushes the second limiting member, thereby rotating the second limiting member, and then making the second limiting member avoid the first limiting portion. At this time, the shelf can be pushed downward to the first position, and the first limiting member is abutted against the first limiting portion to support the shelf. Since the bracket is fixed on the pulley and the second limiting member is connected to the bracket, directly adjusting the second limiting member is susceptible to interference from the bracket, the shelf or the slide rail, which makes it inconvenient to adjust the second limiting member. By providing the adjusting handle, the adjusting handle can be kept away from the bracket and the slide rail, and there is a distance between the adjusting handle and the shelf, thereby reducing the interference of the bracket, the slide rail and the shelf with the adjusting handle, so as to facilitate the adjustment of the second limiting member.

[0013] In some embodiments, the rotation axis of the adjustment handle is perpendicular to the rotation axis of the second limiting member; the first pressing portion includes a first pressing slope and a second pressing slope, and the second pressing slope is located below the first pressing slope; during the movement of the shelf between the first position and the second position, along the direction from the first position to the second position, the distance between the first pressing slope and the side surface of the second limiting member in contact with the first pressing portion gradually increases, and the distance between the second pressing slope and the side surface of the second limiting member in contact with the first pressing portion gradually decreases. In this way, when the shelf moves from the first position to the second position, it contacts the second limiting member through the first guiding slope to push the rotation of the second limiting member. Through the setting of the first pressing slope, it can play a guiding role in the movement of the second limiting member; when the shelf moves from the second position to the first position, it contacts the second limiting member through the second guiding slope to push the rotation of the second limiting member. Through the setting of the second guiding slope, it can play a guiding role in the movement of the second limiting member, so that when the first pressing portion contacts the second limiting member, the rotation of the second limiting member is smoother, and further when adjusting the position of the shelf, it can avoid jamming between the first pressing portion and the second limiting member, thereby improving the smoothness when the first pressing portion pushes the second limiting member. In addition, by setting the rotation axis of the adjustment handle perpendicular to the rotation axis of the second limiting member, when adjusting the position of the shelf, the adjustment handle will occupy less space inside the shelf, and such a setting will be more reasonable.

[0014] In some embodiments, the dishwasher further includes a first elastic member, and the first elastic member is connected to the second limiting member; during the movement of the shelf between the first position and the second position, the second limiting member and the bracket can cause the first elastic member to undergo elastic deformation, so that the first elastic member generates an elastic force on the second limiting member to make a part of the second limiting member rotate below the first limiting portion. In this way, the support of the second limiting member on the first limiting portion can be realized without manual operation, which can reduce the process of manually rotating the second limiting member, thereby simplifying the operation process of adjusting the second limiting member and improving the convenience of adjusting the second limiting member.

[0015] In some embodiments, the first adjusting member includes a fixed handle, and the fixed handle is connected to the shelf. In this way, when it is necessary to adjust the position of the shelf, the fixed handle is pushed or pulled through the handle, so as to facilitate applying a thrust or a pulling force to the shelf, and further facilitate the adjustment of the shelf. Through such a setting, the adjustment of the shelf is more convenient.

[0016] And / or, the adjusting assembly further includes a second elastic member connected to the adjusting handle; during the movement of the shelf between the first position and the second position, the adjusting handle and the first adjusting member can cause the second elastic member to undergo elastic deformation. In this way, the reset of the adjusting handle can be achieved without manual operation, which can reduce the process of people manually rotating the adjusting handle, thereby simplifying the operation process of adjusting the adjusting handle and improving the convenience of adjusting the adjusting handle.

[0017] In some embodiments, a third limiting member is further provided on the bracket, and the third limiting member is located below the first limiting member; a second limiting portion is further formed on the shelf, and the second limiting portion is located below the first limiting portion; when the shelf is in the second position, the second limiting portion is located below the third limiting member and is in contact with the third limiting member. In this way, when the shelf is in the second position, the third limiting member can limit the movement of the second limiting portion in the direction from the first position to the second position, thereby limiting the movement of the shelf in the direction from the first position to the second position; at the same time, the second limiting member can limit the movement of the first limiting portion in the direction from the second position to the first position, thereby limiting the movement of the shelf in the direction from the second position to the first position, so that the shelf will not move in the height direction of the dishwasher, and thus the shelf can be more stable in the second position.

[0018] In some embodiments, in the direction from the second position to the first position, a limiting plane and a guiding inclined surface are sequentially arranged on the limiting boss. Along the direction in which the limiting boss extends into the limiting hole, the distance between the guiding inclined surface and the limiting plane gradually decreases. In this way, when the limiting boss supports the first limiting portion, the limiting plane is in contact with the first limiting portion, so that the support of the limiting boss on the first limiting portion can be more stable. In addition, during the process of the limiting boss entering the limiting hole, the cross-sectional area of one end of the limiting boss that first enters the limiting hole is smaller. Therefore, the limiting boss can enter the limiting hole more easily, and thus the limiting boss can enter the limiting hole more smoothly.

[0019] In some embodiments, the bracket is further provided with a guiding member, and a guiding rod is further formed on the shelf. The guiding rod is connected to the guiding member and can slide relative to the guiding member in the height direction of the dishwasher. In this way, when the shelf moves between the first position and the second position, through the sliding connection between the guiding rod and the guiding member, the guiding member can limit and guide the guiding rod, thereby enabling the guiding member to guide and limit the movement of the shelf, so as to avoid the position deviation of the shelf during the movement and ensure that the shelf is more stable and smooth during the movement.

[0020] According to a second aspect of the present application, a dishwasher is provided, which includes an inner container, a bracket, a shelf, a first limiting member, and a second limiting member. A cleaning cavity is formed inside the inner container; the bracket is arranged inside the cleaning cavity and is connected to the inner container; the shelf is arranged inside the cleaning cavity and is connected to the bracket. Along the height direction of the dishwasher, the shelf can move relative to the bracket between a first position and a second position; a first limiting portion is formed on the shelf; the first limiting member is connected to the bracket; the second limiting member is located above the first limiting member and is rotatably connected to the bracket. When the shelf is in the first position, the first limiting portion is located above the first limiting member and abuts against the first limiting member; when the shelf is in the second position, a part of the second limiting member rotates to below the first limiting portion and abuts against the first limiting portion.

[0021] It should be noted that for the technical effects brought by the implementation manners of the second aspect, reference can be made to the technical effects brought by the corresponding implementation manners in the first aspect, which will not be elaborated here.

[0049] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0051] The terms "first" and "second" are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, when describing pipelines or channels, the terms "connection" and "coupling" used in this application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0053] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or designs. Exactly speaking, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0054] For places with a large consumption of tableware such as restaurants, hotels, and unit canteens, the cleaning of tableware is very cumbersome, which will result in a relatively high working intensity for the staff.

[0055] Based on this, the present application provides a dishwasher, as Figure 1 shown, the dishwasher includes an inner container 1 and a bracket 2. The inner container 1 forms a cleaning cavity 11, and the bracket 2 is disposed in the cleaning cavity 11 and connected to the inner container 1.

[0056] As shown Figure 1 in the figure, the dishwasher further includes a slide rail 3 and a pulley 4. The inner container 1 is formed with an opening connected to the cleaning cavity 11. Slide rails 3 are provided on both side walls of the cleaning cavity 11 in the first direction X, the first direction X is perpendicular to the depth direction of the cleaning cavity 11 and perpendicular to the height direction of the dishwasher.

[0057] Each slide rail 3 is slidably connected to at least one pulley 4. The bracket 2 can be provided in two. One bracket 2 is connected to the pulley 4 slidably connected to one slide rail 3, so that the bracket 2 is connected to the inner container 1 through the pulley 4 and the slide rail 3.

[0058] Exemplarily, the bracket 2 can be a support plate or a support frame formed by connecting multiple rods.

[0059] Exemplarily, the number of pulleys 4 connected to one slide rail 3 can be one or multiple. When the number of pulleys 4 connected to one slide rail 3 is multiple, the multiple pulleys 4 are arranged at intervals along the extension direction of the slide rail 3, and one bracket 2 is rotatably connected to the multiple pulleys 4 on one slide rail 3. It should be noted that the slide rail 3 extends along the depth direction of the cleaning cavity 11.

[0060] As shown Figure 2 in the figure, the dishwasher further includes a shelf 5. The shelf 5 is arranged in the cleaning cavity 11 and is connected to the bracket 2. That is, the two side walls of the shelf 5 in the first direction X are respectively connected to the two brackets 2.

[0061] Exemplarily, the number of shelves 5 can be one or multiple. When the number of shelves 5 is multiple, the multiple shelves 5 are arranged at intervals in the vertical direction.

[0062] In this way, when the tableware needs to be cleaned, the shelf 5 can be pulled out of the cleaning cavity 11 from the opening of the cleaning cavity 11, then the tableware to be cleaned is placed on the shelf 5, and then the shelf 5 is pushed into the cleaning cavity 11 through the opening, and then the tableware on the shelf 5 is cleaned.

[0063] When cleaning the tableware, there will be tableware with a relatively large height, such as high-footed cups, etc. At this time, it may occur that the space above the shelf 5 cannot accommodate the tableware with a relatively large height, thus affecting the cleaning of the tableware by the dishwasher.

[0064] To avoid the above situation, along the height direction of the dishwasher, the shelf 5 can move between a first position and a second position relative to the bracket 2, and the first position is below the second position.

[0065] In this way, when tableware with a relatively high height needs to be cleaned, as shown Figure 3As shown, the shelf 5 can be adjusted to the first position to increase the space above the shelf 5, so that tableware with a relatively high height can be placed on the shelf 5, thereby enabling the cleaning of tableware with a relatively high height.

[0066] When there is no need to clean tableware with a relatively high height, such as Figure 4 As shown, the shelf 5 can be adjusted to the second position to make the spaces above and below the shelf 5 more appropriate, thereby facilitating the placement of tableware above and below the shelf 5.

[0067] After the position of the shelf 5 is adjusted, in order to facilitate the support of the shelf 5, such as Figure 5 As shown, a first limiting portion 51 is formed on the shelf 5. As Figure 6 As shown, the dishwasher further includes a first limiting member 6 and a second limiting member 7. The second limiting member 7 is located above the first limiting member 6.

[0068] The first limiting member 6 is connected to the bracket 2. When the shelf 5 is in the first position, as Figure 5 As shown, the first limiting portion 51 is located above the first limiting member 6 and abuts against the first limiting member 6. In this way, the first limiting member 6 can support the first limiting portion 51, thereby supporting the shelf 5 so that the shelf 5 is stably located in the first position.

[0069] Exemplarily, the first limiting member 6 can be a limiting plate, a limiting rod, or a limiting block.

[0070] Exemplarily, the first limiting portion 51 can be a limiting plate, a limiting rod, or a limiting block.

[0071] The second limiting member 7 is rotatably connected to the bracket 2. When the shelf 5 is in the second position, as Figure 7 As shown, a part of the second limiting member 7 rotates to the lower side of the first limiting portion 51 and abuts against the first limiting portion 51. In this way, the second limiting member 7 can support the first limiting portion 51, thereby supporting the shelf 5 so that the shelf 5 is stably located in the second position.

[0072] In some examples, the direction of the rotation axis of the second limiting member 7 is the same as the height direction of the dishwasher, or can also be the same as the depth direction of the cleaning cavity 11. At this time, the first limiting portion 51 can be located on the outer side wall of the shelf 5 close to the bracket 2, or can also be located on the inner side wall of the shelf 5 far from the bracket 2.

[0073] It should be noted that a placement cavity with an upward opening is formed on the shelf 5, and tableware is placed in the placement cavity. In addition, in order to facilitate drainage, a plurality of slits are usually formed on the side wall and the bottom wall of the shelf 5. Therefore, when the first stopper 51 is located on the inner side wall of the shelf 5 away from the bracket 2, part of the second stopper 7 can rotate to the inner side of the shelf 5 through the slit and abut against the first stopper 51.

[0074] In some other examples, the direction of the rotation axis of the second limiting member 7 may also be consistent with the first direction X. At this time, the first limiting portion 51 is located on the outer side wall of the shelf 5 close to the bracket 2 .

[0075] When the shelf 5 is adjusted from the first position to the second position, as shown in FIG. Figure 8 As shown, the second limiting member 7 can be rotated so that the part of the second limiting member 7 located below the first limiting portion 51 is rotated to the side of the first limiting portion 51 in the vertical direction of the dishwasher, so that the second limiting member 7 avoids the first limiting portion 51, and then the shelf 5 is pushed upward to move the first limiting portion 51 to the upper side of the second limiting member 7 in the vertical direction. Then, as shown in FIG. Figure 7 As shown, the second limiting member 7 is rotated in the opposite direction so that part of the second limiting member 7 is rotated to just below the first limiting portion 51 and abuts against the first limiting portion 51 .

[0076] When the shelf 5 is adjusted from the second position to the first position, the second limiting member 7 can be rotated. Figure 8 As shown, the portion of the second limiting member 7 located below the first limiting portion 51 is rotated to the side of the first limiting portion 51 in a direction perpendicular to the height of the dishwasher, so that the second limiting member 7 avoids the first limiting portion 51, and then the shelf 5 is pushed downward to move the first limiting portion 51 to the top of the first limiting member 6 and abut against the first limiting member 6.

[0077] In the above adjustment process, it is only necessary to rotate the second limit member 7 and push the shelf 5 up and down. It is not necessary to pull the shelf 5 out of the cleaning chamber 11 or to disassemble the shelf 5. Therefore, the adjustment process of the shelf 5 can be simplified, thereby making the adjustment of the shelf 5 more convenient.

[0078] Exemplarily, the second limiting member 7 is rod-shaped. At this time, the axis of the second limiting member 7 is perpendicular to the height direction of the dishwasher. When the rack 5 is in the second position, the second limiting rod is rotated to rotate one end of the second limiting rod to the bottom of the first limiting portion 51 and abut against the first limiting portion 51, so that the rack 5 can be supported.

[0079] For example, Figure 9 As shown, the second limiting member 7 includes a rotating plate 71 and a limiting boss 72. Figure 8As shown, the rotating plate 71 is rotatably connected to the bracket 2. The direction Y of the rotation axis of the rotating plate 71 is consistent with the height direction of the dishwasher. The limiting boss 72 is connected to the rotating plate 71, and at least part of the limiting boss 72 is located on one side of the rotating plate 71 along the direction Z in which the limiting boss 72 rotates closer to the first limiting portion 51.

[0080] At this time, when the shelf 5 is in the second position, by rotating the rotating plate 71, the limiting boss 72 can be driven to rotate, so that the limiting boss 72 can be rotated below the first limiting portion 51 and the limiting boss 72 can be abutted against the first limiting portion 51 to support the shelf 5.

[0081] In this way, by rotating the rotating plate 71 by a small amplitude, the limiting boss 72 can be rotated below the first limiting portion 51, thereby avoiding the situation that the rotating plate 71 rotates too much and occupies the space of the cleaning cavity 11 in the first direction X, so that the space of the cleaning cavity 11 can be reasonably utilized.

[0082] Among them, in some examples, the thickness direction of the rotating plate 71 can be perpendicular to the height direction of the dishwasher or parallel to the height direction of the dishwasher.

[0083] In some examples, the rotating plate 71 can be located on the side of the bracket 2 away from the shelf 5 or between the bracket 2 and the shelf 5.

[0084] On this basis, in order to prevent the rotation position of the limiting boss 72 from deviating from the first limiting portion 51 and affecting the supporting effect of the limiting boss 72 on the first limiting portion 51, as Figure 10 shown, a limiting hole 21 is formed on the bracket 2. The limiting hole 21 is located above the first limiting member 6, and the axial direction of the limiting hole 21 is perpendicular to the rotation axis of the second limiting member 7.

[0085] The rotating plate 71 can drive the limiting boss 72 to pass through or withdraw from the limiting hole 21. Specifically, during the process of the shelf 5 moving from the first position to the second position, as Figure 8 shown, the limiting boss 72 withdraws from the limiting hole 21 to avoid the first limiting portion 51; when the shelf 5 moves to the second position, as Figure 7 shown, the limiting boss 72 passes through the limiting hole 21 so that the limiting boss 72 is located below the first limiting portion 51 and abuts against the first limiting portion 51.

[0086] In this way, after rotating the limiting plate to drive the limiting boss 72 to extend into the limiting hole 21, the side wall of the bracket 2 close to the rotating plate 71 can abut against one end of the rotating plate 71 close to the limiting boss 72, thereby restricting the axial movement of the rotating plate 71 in the limiting hole 21, and further restricting the axial movement of the boss in the limiting hole 21, so as to prevent the rotation amplitude of the limiting boss 72 from being too large, resulting in the inability of the limiting boss 72 to support the first limiting portion 51, or the contact area between the limiting boss 72 and the first limiting portion 51 being small, which affects the support effect on the first limiting portion 51.

[0087] Moreover, after the limiting boss 72 passes through the limiting hole 21, the limiting hole 21 can restrict the movement of the limiting boss 72 in the direction perpendicular to the axis of the limiting hole 21, so that the limiting boss 72 is more stable in the limiting hole 21, and further makes the support of the limiting boss 72 on the first limiting portion 51 more stable.

[0088] Exemplarily, the limiting hole 21 can be a through hole in the shape of a circle, an ellipse, a square, etc. Correspondingly, the limiting boss 72 can be a columnar structure or a block structure in the shape of a circle, an ellipse, a square, etc.

[0089] In order to enable the limiting boss 72 to smoothly pass through the limiting hole 21, as Figure 9 shown, along the direction from the second position to the first position, a limiting plane 721 and a guiding inclined plane 722 are sequentially arranged on the limiting boss 72.

[0090] The limiting plane 721 is perpendicular to the height direction of the dishwasher, and when the shelf 5 moves to the second position, as Figure 7 shown, the limiting plane 721 abuts against the first limiting portion 51. In this way, when the limiting boss 72 supports the first limiting portion 51, the contact is made through the limiting plane 721 and the first limiting portion 51, so that the support of the limiting boss 72 on the first limiting portion 51 can be more stable.

[0091] As Figure 10 shown, along the direction in which the limiting boss 72 extends into the limiting hole 21, the distance between the guiding inclined plane 722 and the limiting plane 721 gradually decreases. In this way, during the process of the limiting boss 72 entering the limiting hole 21, the cross-sectional area of one end of the limiting boss 72 that first enters the limiting hole 21 is smaller. Therefore, the limiting boss 72 can enter the limiting hole 21 more easily, and thus the limiting boss 72 enters the limiting hole 21 more smoothly.

[0092] After the shelf 5 moves to the second position, in order to enable the second limiting member 7 to quickly support the first limiting portion 51, as Figure 9 shown, the dishwasher further includes a first elastic member 8. The first elastic member 8 is connected to the second limiting member 7.

[0093] AsFigure 8 As shown, during the movement of the shelf 5 between the first position and the second position, the second limiting member 7 and the bracket 2 can cause the first elastic member 8 to undergo elastic deformation, and the first elastic member 8 can generate an elastic force on the second limiting member 7 to cause a part of the second limiting member 7 to rotate below the first limiting portion 51.

[0094] It should be noted that when the shelf 5 is in the first position or the second position, the first elastic member 8 is in a natural state or a state with a small elastic deformation.

[0095] During the movement of the shelf 5 from the first position to the second position, it is necessary to rotate the second limiting member 7 to avoid the first limiting portion 51. At this time, the second limiting member 7 will drive the first elastic member 8 to move, so that under the action of the second limiting member 7 and the bracket 2, the first elastic member 8 is squeezed or stretched, thereby causing the first elastic member 8 to undergo elastic deformation.

[0096] When the shelf 5 is adjusted to the second position, the first elastic member 8 can generate an elastic force on the second limiting member 7 to cause a part of the second limiting member 7 to rotate below the first limiting portion 51. At this time, stop rotating the second limiting member 7, and the second limiting member 7 will automatically rotate in the reverse direction under the elastic force of the first elastic member 8, so that a part of the second limiting member 7 automatically rotates below the first limiting portion 51 to support the first limiting portion 51.

[0097] In this way, the support of the second limiting member 7 for the first limiting portion 51 can be realized without manual operation, which can reduce the process of people manually rotating the second limiting member 7, thereby simplifying the operation process of adjusting the second limiting member 7 and improving the convenience of adjusting the second limiting member 7.

[0098] Here, taking the second limiting member 7 including a rotating plate 71 and a limiting boss 72, and the rotation axis of the rotating plate 71 being consistent with the height direction of the dishwasher as an example, a part of the second limiting member 7 is the limiting boss 72.

[0099] At this time, when the shelf 5 is in the second position, the limiting boss 72 is located in the limiting hole 21. If the limiting boss 72 is accidentally touched or impacted, etc., since the first elastic member 8 can generate an elastic force on the second limiting member 7 to cause the limiting boss 72 to rotate below the first limiting portion 51, the limiting boss 72 can be prevented from exiting the limiting hole 21, so that the support of the limiting boss 72 for the first limiting portion 51 can be more stable.

[0100] In some examples, the first elastic member 8 can be a spring. One end of the spring is connected to the end of the rotating plate 71 close to the limiting boss 72, and the other end of the spring is connected to the bracket 2. At this time, during the process of the second limiting member 7 avoiding the first limiting portion 51, the spring is stretched.

[0101] One end of the spring can also be connected to the end of the rotating plate 71 away from the limiting boss 72, and the other end of the spring is connected to the bracket 2. Moreover, the rotation axis of the rotating plate 71 is located between the spring and the limiting boss 72. At this time, during the process of the second limiting member 7 avoiding the first limiting portion 51, the spring is compressed.

[0102] In some other examples, such as Figure 8 As shown, the first elastic member 8 is an elastic plate or an elastic sheet. At this time, one end of the first elastic member 8 is connected to the end of the rotating plate 71 away from the limiting boss 72, and the other end of the first elastic member 8 is located on the side of the rotating plate 71 close to the bracket 2. Moreover, the rotation axis of the rotating plate 71 is located between the first elastic member 8 and the limiting boss 72. At this time, during the process of the second limiting member 7 avoiding the first limiting portion 51, the first elastic member 8 is squeezed.

[0103] In some embodiments, such as Figure 11 As shown, the bracket 2 is further provided with a guiding member 22. As Figure 5 shown, a guiding rod 52 is further formed on the shelf 5. The guiding rod 52 is connected to the guiding member 22 and can slide relative to the guiding member 22 along the height of the dishwasher.

[0104] In this way, when the shelf 5 moves between the first position and the second position, through the sliding connection between the guiding rod 52 and the guiding member 22, the guiding member 22 can limit and guide the guiding rod 52, so that the guiding member 22 can guide and limit the movement of the shelf 5, so as to avoid the position deviation of the shelf 5 during the movement and ensure that the shelf 5 is more stable and smooth during the movement.

[0105] Exemplarily, such as Figure 11 shown, the guiding member 22 is a plurality of bumps 221 arranged at intervals along the height direction of the dishwasher. Each bump is formed with a guiding groove 222 penetrating the bump 221 along the height direction of the dishwasher. The guiding rod 52 is slidably connected in a plurality of guiding grooves 222.

[0106] Exemplarily, the guiding member 22 is a guiding cylinder, the axis of the guiding cylinder is consistent with the height direction of the dishwasher, or the guiding member 22 is a plurality of guiding rings arranged at intervals along the height direction of the dishwasher.

[0107] Exemplarily, the number of the guiding rod 52 and the guiding member 22 can both be one. The number of the guiding rod 52 and the guiding member 22 can both be multiple. At this time, a plurality of guiding rods 52 correspond to a plurality of guiding members 22 one by one, and one guiding rod 52 is slidably connected to one guiding member 22.

[0108] In some embodiments, such as Figure 10As shown, the bracket 2 is also provided with a third limiting member 23, and the third limiting member 23 is located below the first limiting member 6. Figure 7 As shown, a second limiting portion 53 is further formed on the shelf 5 , and the second limiting portion 53 is located below the first limiting portion 51 .

[0109] When the shelf 5 is located at the second position, the second limiting portion 53 is located below the third limiting member 23 and contacts the third limiting member 23 .

[0110] Through the above arrangement, when the shelf 5 is in the second position, the third limiting member 23 can limit the second limiting portion 53 from moving in the direction from the first position to the second position, thereby limiting the shelf 5 from moving in the direction from the first position to the second position; at the same time, the second limiting member 7 can limit the first limiting portion 51 from moving in the direction from the second position to the first position, thereby limiting the shelf 5 from moving in the direction from the second position to the first position.

[0111] In this way, the movement of the rack 5 in the height direction of the dishwasher will be restricted, so that the rack 5 can be more stable in the second position.

[0112] Furthermore, during the movement of the shelf 5 from the first position to the second position, the third limiting member 23 limits the second limiting portion 53, thereby preventing the first limiting portion 51 from being too far away from the second limiting member 7 after moving to the top of the second limiting member 7, thereby quickly stabilizing the shelf 5 in the second position to improve the adjustment efficiency of the shelf 5.

[0113] Exemplarily, the third limiting member 23 may be a limiting rod, a limiting plate, a limiting block, or the like.

[0114] Exemplarily, the second limiting portion 53 may be a limiting rod, a limiting plate, a limiting block, etc.

[0115] In some embodiments, in order to make the adjustment of the second limiter 7 more convenient, as shown in FIG. Figure 12 As shown, the dishwasher also includes an adjustment component 9, which includes a first adjustment member 91 and an adjustment handle 92. The first adjustment member 91 is connected to the rack 5, and the adjustment handle 92 is rotatably connected to the first adjustment member 91 and is spaced apart from the rack 5. A first extrusion portion 921 is formed on the adjustment handle 92.

[0116] During the movement of the shelf 5 between the first position and the second position, Figure 13 As shown, the first pressing portion 921 can contact the second limiting member 7 and push the second limiting member 7 to rotate, so that the second limiting member 7 avoids the first limiting portion 51 .

[0117] In this way, when the shelf 5 needs to be moved from the first position to the second position, people can directly pull the first adjusting member 91 in the direction from the first position to the second position, thereby driving the shelf 5 to move.

[0118] During this process, the first adjusting member 91 can also drive the adjusting handle 92 to move accordingly. Figure 14 As shown, the first pressing portion 921 on the adjusting handle 92 can contact the second limiting member 7 and push the second limiting member 7 to rotate, so that the second limiting member 7 avoids the first limiting portion 51, so that the shelf 5 can smoothly reach the second position.

[0119] People can also adjust the handle 92 by rotating it. Figure 15 As shown, the first pressing portion 921 pushes the second limiting member 7, thereby causing the second limiting member 7 to rotate, thereby causing the second limiting member 7 to avoid the first limiting portion 51, and at the same time, pulling the shelf 5 upward to move the shelf 5 to the second position.

[0120] After the shelf 5 moves to the second position, the first extrusion portion 921 moves to the top of the second limiting member 7 and no longer pushes the second limiting member 7 to rotate. At this time, the second limiting member 7, under the action of the first elastic member 8, will cause part of the second limiting member 7, namely the limiting boss 72, to rotate to the bottom of the first limiting portion 51 to support the first limiting portion 51.

[0121] When the shelf 5 needs to be moved from the second position to the first position, the adjustment handle 92 is rotated. Figure 15 As shown, the first extrusion portion 921 pushes the second limiting member 7, thereby causing the second limiting member 7 to rotate, and then causing the second limiting member 7 to avoid the first limiting portion 51. At this time, the shelf 5 can be pushed downward to the first position, and the first limiting member 6 is abutted against the first limiting portion 51 to support the shelf 5.

[0122] Since the bracket 2 is fixed on the pulley 4 and the second position-limiting member 7 is connected to the bracket 2, directly adjusting the second position-limiting member 7 is easily interfered by the bracket 2, the shelf 5 or the slide rail 3, which makes it inconvenient to adjust the second position-limiting member 7. By providing the adjustment handle 92, the adjustment handle 92 can be kept away from the bracket 2 and the slide rail 3, and there is a distance between the adjustment handle 92 and the shelf 5, so that the interference of the bracket 2, the slide rail 3 and the shelf 5 on the adjustment handle 92 can be reduced, so as to facilitate the adjustment of the second position-limiting member 7.

[0123] Exemplarily, the rotation axis D of the adjustment handle 92 may be parallel to the rotation axis E of the second position-limiting member 7 , or may be perpendicular to the rotation axis E of the second position-limiting member 7 .

[0124] When the rotation axis D of the adjustment handle 92 is perpendicular to the rotation axis E of the second stopper 7, as shown in FIG. Figure 14As shown, the first extrusion part 921 includes a first extrusion inclined surface 9211 and a second extrusion inclined surface 9212, and the second extrusion inclined surface 9212 is located below the first extrusion inclined surface 9211.

[0125] During the movement of the shelf 5 between the first position and the second position, along the direction from the first position to the second position, the distance between the first extrusion inclined surface 9211 and the side surface of the second limiting member 7 in contact with the first extrusion part 921 gradually increases, and the distance between the second extrusion inclined surface 9212 and the side surface of the second limiting member 7 in contact with the first extrusion part 921 gradually decreases.

[0126] In this way, when the shelf 5 moves from the first position to the second position, as Figure 14 shown, by contacting the second limiting member 7 through the first extrusion inclined surface 9211 to push the second limiting member 7 to rotate, through the setting of the first extrusion inclined surface 9211, the movement of the second limiting member 7 can be guided.

[0127] When the shelf 5 moves from the second position to the first position, as Figure 16 shown, by contacting the second limiting member 7 through the second extrusion inclined surface 9212 to push the rotation of the second limiting member 7, through the setting of the second extrusion inclined surface 9212, the movement of the second limiting member 7 can be guided, so that when the first extrusion part 921 contacts the second limiting member 7, the second limiting member 7 rotates more smoothly, and further when adjusting the position of the shelf 5, jamming between the first extrusion part 921 and the second limiting member 7 is avoided, thereby improving the smoothness when the first extrusion part 921 pushes the second limiting member 7.

[0128] In addition, by setting the rotation axis D of the adjusting handle 92 perpendicular to the rotation axis E of the second limiting member 7, when adjusting the position of the shelf 5, the adjusting handle 92 will occupy less space inside the shelf 5, and such a setting will be more reasonable.

[0129] Exemplarily, the first adjusting member 91 can be an adjusting plate or an adjusting block.

[0130] Exemplarily, as Figure 12 shown, the first adjusting member 91 includes a fixed handle 911, and the fixed handle 911 is connected to the shelf 5.

[0131] In this way, when it is necessary to adjust the position of the shelf 5, by pushing or pulling the fixed handle 911 through the handle, it is convenient to apply a thrust or a pulling force to the shelf 5, and further it is convenient to adjust the shelf 5. Through such a setting, the adjustment of the shelf 5 is more convenient.

[0132] As Figure 14As shown, the adjustment assembly 9 further includes a second elastic member 93. The second elastic member 93 is connected to the adjustment handle 92. When the shelf 5 moves between the first position and the second position, Figure 17 As shown, the adjustment handle 92 and the first adjustment member 91 can cause the second elastic member 93 to undergo elastic deformation.

[0133] It should be noted that, when the shelf 5 is in the first position or the second position, the second elastic member 93 is in a natural state or a state with a small elastic deformation.

[0134] When the shelf 5 is between the first position and the second position, the first adjusting member 91 and the adjusting handle 92 squeeze or stretch the second elastic member 93 so that the second elastic member 93 is in a state of having a large elastic deformation.

[0135] Here, an example is taken in which the rotation axis of the adjustment handle is perpendicular to the rotation axis of the second limiting member.

[0136] When the shelf 5 moves from the first position to the second position, the first adjusting member 91 needs to be pulled upwards. At this time, the first extrusion slope 9211 of the first extrusion portion of the adjusting handle 92 will contact the second limiting member 7 and squeeze the second limiting member 7. Therefore, under the reaction of the second limiting member 7, the adjusting handle 92 will rotate, so that the adjusting handle 92 will drive the second elastic member 93 to move accordingly. Therefore, under the action of the adjusting handle 92 and the first adjusting member 91, the second elastic member 93 is squeezed or stretched, so that the second elastic member 93 undergoes elastic deformation.

[0137] Since the second elastic member 93 has elastic force after elastic deformation, when the shelf 5 is adjusted to the second position, the first extrusion portion and the second limit member 7 are no longer squeezed, and the second elastic member 93 will be reset, so that the adjustment handle 92 will automatically rotate in the opposite direction under the elastic force of the second elastic member 93, so that the adjustment handle 92 automatically rotates to the position where the second elastic member 93 is not squeezed or stretched. When the shelf 5 moves from the second position to the first position, it is necessary to rotate the adjustment handle 92 to push the second limit member 7 to rotate, so that the second limit member 7 avoids the first limit portion 51. At this time, the adjustment handle 92 will drive the second elastic member 93 to move, so that under the action of the first adjustment member 91 and the adjustment handle 92, the second elastic member 93 is squeezed or stretched, so that the second elastic member 93 undergoes elastic deformation.

[0138] When the shelf 5 is adjusted to the first position, the handle 92 is stopped being adjusted, and the second elastic member 93 is reset, so that the handle 92 automatically rotates in the opposite direction under the elastic force of the second elastic member 93, so that the handle 92 automatically rotates to the position where the second elastic member 93 is not squeezed or stretched.

[0139] In this way, the reset of the adjusting handle 92 can be achieved without manual operation, which can reduce the process of people manually rotating the adjusting handle 92, thereby simplifying the operation process of adjusting the adjusting handle 92 and improving the convenience of adjusting the adjusting handle 92.

[0140] In some examples, the second elastic member 93 is a spring. One end of the spring is connected to one end of the adjusting handle 92 close to the first pressing portion 921, and the other end of the spring is connected to the first adjusting member 91. At this time, during the process of rotating the adjusting handle 92, the spring is stretched.

[0141] One end of the spring can also be connected to the end of the adjusting handle 92 away from the first pressing portion 921, and the other end of the spring is connected to the first adjusting member 91. At this time, during the process of rotating the adjusting handle 92, the spring is compressed.

[0142] In other examples, the second elastic member 93 is an elastic plate or an elastic sheet. At this time, one end of the second elastic member 93 is connected to the end of the adjusting handle 92 away from the first pressing portion 921, and the other end of the second elastic member 93 is located above the adjusting handle 92 and can contact the first adjusting member 91. Moreover, the rotation axis of the adjusting handle 92 is located between the second elastic member 93 and the first pressing portion 921. At this time, during the process of rotating the adjusting handle 92, the second elastic member 93 is squeezed.
