[0046] Specific combination Figures 1 to 6 As shown, the outer adjustment frame 100 and the inner adjustment frame 200 are both configured to be barrel-shaped, the opening of the first accommodating cavity passes through the front wall of the outer adjustment frame 100, the inner adjustment frame 200 is slidably disposed in the first accommodating cavity, a plurality of pulley fixing columns 110 are arranged at intervals on the outer wall of the outer adjustment frame 100 away from the inner adjustment frame 200, the pulleys are rotatably connected to the pulley fixing columns 110, a slideway is correspondingly arranged on the inner wall of the cleaning cavity, the pulleys and the slideway are rollingly matched to realize that the height adjustment device drives the shelf 600 to extend or retract into the cleaning cavity; a plurality of shelf card slots 220 are arranged at intervals on the end surface of the inner adjustment frame 200 away from the outer adjustment frame 100, and the plurality of shelf card slots 220 are connected to the shelf 600, as shown in FIG. Figure 1 As shown. With such a configuration, when the height of the shelf 600 needs to be adjusted, the position of the adjusting inner frame 200 is adjusted so that the adjusting inner frame 200 slides relative to the adjusting outer frame 100, thereby changing the relative position of the adjusting inner frame 200 and the adjusting outer frame 100; since the adjusting outer frame 100 is connected to the inner wall of the washing chamber in the dishwasher, and the adjusting inner frame 200 is connected to the shelf 600 of the dishwasher, the height of the shelf 600 in the dishwasher can be adjusted to meet the use requirements of different use scenarios; and the height of the shelf 600 in the dishwasher can be adjusted by sliding the adjusting inner frame 200 relative to the adjusting outer frame 100, while ensuring the use effect, the structure is relatively simple, thereby reducing the production cost. In addition, since the limit assembly 400 is arranged in the adjustment inner frame 200, the second limit member 430 is arranged in the adjustment outer frame 100, and the second limit member 430 cooperates with the limit assembly 400, when the height adjustment of the shelf 600 is completed, by adjusting the cooperation relationship between the second limit member 430 and the limit assembly 400, the relative position of the adjustment outer frame 100 and the adjustment inner frame 200 in this state can be limited, thereby avoiding the sudden fall of the shelf 600, thereby improving the safety of use.

[0047] In the optional technical solution of this embodiment, the height adjustment device includes an adjustment component 300 and a limit component 400. The limit component 400 is arranged between the adjustment outer frame 100 and the adjustment inner frame 200. The adjustment component 300 is transmission-connected to the limit component 400 to adjust the position of the limit component 400.

[0048] Specific combination Figure 3 , Figure 4 and Figure 6 As shown, in this configuration, the adjustment component 300 is used to adjust the position of the limit component 400, so as to facilitate limiting or releasing the limit on the position of the adjustment inner frame 200. When the limit on the position of the adjustment inner frame 200 is released, the adjustment inner frame can be slid to change the relative position between the adjustment outer frame 100 and the adjustment inner frame 200, so as to adjust the height of the shelf 600 in the dishwasher, so as to meet the use requirements of different use scenarios. The limit component 400 is used to limit the relative position of the adjustment outer frame 100 and the adjustment inner frame 200, so as to avoid the situation that the adjustment outer frame 100 and the adjustment inner frame 200 are in a straight line after the height adjustment, and further improve the use effect of the height adjustment device.

[0049] In the optional technical solution of this embodiment, the limiting assembly 400 includes a sliding block 410, a first limiting member 420 and a second limiting member 430, and the adjusting inner frame 200 is provided with a second accommodating cavity;

[0050] The sliding block 410 is arranged in the second accommodating cavity and is transmission-connected to the adjusting assembly 300. The first limiting member 420 is arranged on the sliding block 410 and extends out of the side wall of the second accommodating cavity. The second limiting member 430 is arranged on the side wall of the first accommodating cavity. The first limiting member 420 and the second limiting member 430 are limit-connected.

[0051] Specific combination Figure 3 , Figure 4 and Figure 6 As shown, when the sliding block 410 is adjusted to move in a direction away from the side wall of the first accommodating chamber through the adjustment component 300, the first limit piece 420 is driven to move in a direction close to the center of the adjusting inner frame 200, so that the first limit piece 420 and the second limit piece 430 are disengaged. At this time, the handle 310 is lifted upward to make the adjusting inner frame 200 move upward relative to the adjusting outer frame 100, completing a height adjustment; when the sliding block 410 is adjusted to move in a direction close to the side wall of the first accommodating chamber through the adjustment component 300, the first limit pieces 420 arranged on the two sliding blocks 410 are respectively moved in a direction away from the center of the adjusting inner frame 200, so that the first limit piece 420 and the second limit piece 430 are engaged again, limiting the adjusting inner frame 200 to the current position, avoiding the situation where the adjusting inner frame 200 falls back after adjustment, and further ensuring the adjustment effect.

[0052] In the optional technical solution of this embodiment, a plurality of first limit members 420 and a plurality of second limit members 430 are provided, and the plurality of first limit members 420 and the plurality of second limit members 430 are spaced apart in the first direction, and an avoidance groove is provided on the side wall of the first accommodating cavity, and the plurality of second limit members 430 can be telescopically provided on the bottom wall of the avoidance groove.

[0053] Specific combination Figure 3 , Figure 4 and Figure 6 As shown, in this arrangement, the plurality of first limiting members 420 and the plurality of second limiting members 430 cooperate with each other, further increasing the gears of the adjustable relative position between the outer frame 100 and the inner frame 200, thereby increasing the gears of the adjustable height of the shelf 600 to meet the use requirements of different use scenarios. In addition, since the second limiting member 430 is retractably arranged on the bottom wall of the avoidance groove through the elastic member, during the position adjustment process, with the assistance of the elastic member, the second limiting member 430 is adaptively extended or retracted in the avoidance groove according to the adjustment position, avoiding interference with other components, thereby ensuring the use effect.

[0054] In an optional technical solution of the present embodiment, two groups of limit assemblies 400 are provided, the two groups of limit assemblies 400 are arranged in the second accommodating cavity at intervals along the second direction, and the two groups of limit assemblies 400 are transmission-connected to the adjustment assembly 300 .

[0055] Specific combination Figure 3 , Figure 4 and Figure 6 As shown, the number of the limiter components 400 can be appropriately increased or decreased according to the specific situation. In this embodiment, there are two groups of limiter components 400, and the two groups of limiter components 400 are respectively arranged corresponding to the two side walls of the second accommodating cavity. In this way, on the one hand, the two groups of limiter components 400 cooperate with each other to further enhance the limiting effect of adjusting the position of the inner frame 200. On the other hand, the two groups of limiter components 400 are respectively arranged corresponding to the two side walls of the second accommodating cavity, so that the adjustment component 300 is not exposed to the outer peripheral wall of the height adjustment component 300, and the interference between the limiter components 400 and other components is avoided while ensuring the use effect of the limiter components 400.

[0056] In an optional technical solution of this embodiment, the adjustment component 300 includes a handle 310, a connecting rod adjustment group or a gear adjustment group, the handle 310 is fixedly arranged on the outer wall of the adjustment inner frame 200, and the connecting rod adjustment group or the gear adjustment group is transmission-connected to the sliding block 410.

[0057] Specific combination Figure 3 , Figure 4 and Figure 6As shown, by adjusting the connecting rod adjustment group or the gear adjustment group, the two sliding blocks 410 are driven to move closer to or away from each other, that is, the first limit member 420 and the second limit member 430 are disengaged, or the first limit member 420 and the second limit member 430 are engaged again; when the first limit member 420 and the second limit member 430 are disengaged, the handle 310 is lifted upward to make the adjustment inner frame 200 move upward relative to the adjustment outer frame 100, completing a height adjustment; when one adjustment is completed, the first limit member 420 and the second limit member 430 are engaged again to limit the adjustment inner frame 200 to the current position, thereby avoiding the adjustment inner frame 200 from falling back after adjustment, thereby further ensuring the adjustment effect.

[0058] In addition, the connecting rod adjustment group and the gear adjustment group are both arranged at a fixed ratio close to the adjustment inner frame 200, and the handle 310 is arranged on the side wall opposite to the bottom wall of the first accommodating cavity of the adjustment inner frame 200, and is protruded from the side wall. The bottom wall of the first accommodating cavity is correspondingly provided with an avoidance section, and the handle 310 extends out of the avoidance section; on the one hand, the use effect of the handle 310 is ensured, and the smooth progress of the height adjustment process is ensured. On the other hand, the avoidance section and the handle 310 cooperate to play a limiting role to prevent the adjustment inner frame 200 and the adjustment outer frame 100 from separating from each other, thereby further improving the use effect of the height adjustment device.

[0059] In an optional technical solution of this embodiment, the connecting rod adjustment group includes a first adjustment member 321 and a second adjustment rod 322. The first adjustment member 321 abuts between the two sliding blocks 410. One end of the second adjustment rod 322 is fixedly connected to the first adjustment member 321, and the other end extends out of the second accommodating cavity.

[0060] When the adjustment group is set to the connecting rod adjustment group, the specific combination Figure 3 and Figure 4 As shown, the first adjusting member 321 is set to an irregular shape. When the second adjusting rod 322 is rotated, the second adjusting rod 322 drives the first adjusting member 321 to rotate. Since the first adjusting member 321 abuts between the two sliding blocks 410, the distance between the two sliding blocks 410 can be changed, thereby realizing the disengagement or cooperation between the first limiting member 420 and the second limiting member 430, thereby realizing the movement or relative position fixing between the adjusting inner frame 200 and the adjusting outer frame 100.

[0061] In the optional technical solution of the present embodiment, the surfaces of the two sliding blocks 410 that are close to each other are provided with abutment cavities, the first adjusting member 321 includes a first abutment rod 3211, a second abutment rod 3212 and a connecting rod 3213, the two ends of the connecting rod 3213 are respectively connected to the position close to the first end of the first abutment rod 3211 and the position close to the first end of the second abutment rod 3212, the second adjusting rod 322 is fixedly connected to the middle part of the connecting rod 3213, and the second adjusting rod 322 is rotated along the circumference of the second accommodating cavity to change the distance between the two sliding blocks 410.

[0062] Specific combination Figure 3 and Figure 4 As shown, the first adjusting member 321 includes a first abutting rod 3211, a second abutting rod 3212 and a connecting rod 3213, and the first abutting rod 3211, the second abutting rod 3212 and the connecting rod 3213 are all configured to be rod-shaped; the two ends of the connecting rod 3213 are respectively connected to a position close to the first end of the first abutting rod 3211 and a position close to the first end of the second abutting rod 3212, so that the first adjusting member 321 is approximately in the shape of an "I"; the second adjusting rod 322 is fixedly connected to the middle part of the connecting rod 3213, and the axis of the second adjusting rod 322 is parallel to the axis of the connecting rod 3213; and the second end of the first abutting rod 3211 and the second end of the second abutting rod 3212 are both provided with an auxiliary rod, the auxiliary rod is vertically arranged with the second abutting rod 3212, and when the second adjusting rod 322 is rotated along the circumference of the second accommodating cavity, the two auxiliary rods are always located in the corresponding abutting cavity. When the first end of the first abutment rod 3211 and the first end of the second abutment rod 3212 are respectively abutted against the end surfaces of the two sliding blocks 410 that are close to each other, and the two auxiliary rods are abutted against the bottom wall of the abutment cavity, the distance between the two sliding blocks 410 is reduced, and the first limiting member 420 and the second limiting member 430 are disengaged; when the first end of the first abutment rod 3211 and the first end of the second abutment rod 3212 are not abutted against the end surfaces of the two sliding blocks 410 that are close to each other, and the two auxiliary rods are abutted against the bottom wall of the abutment cavity, the distance between the two sliding blocks 410 is increased, and the first limiting member 420 and the second limiting member 430 are matched again to limit the relative position of the adjustment inner frame 200 and the adjustment outer frame 100.

[0063] In addition, since the second end of the first abutting rod 3211 and the second end of the second abutting rod 3212 are both provided with an auxiliary rod, the abutting rod and the second abutting rod 3212 are vertically arranged. In this arrangement, the auxiliary rod cooperates with the corresponding abutting cavity to limit the first adjustment member 321, so as to prevent the first adjustment member 321 from being separated from the sliding block 410 during the adjustment process, thereby further ensuring the use effect of the height adjustment device. When the second adjustment rod 322 is fixedly connected to the middle part of the connecting rod 3213, a limiting member is provided between the middle part of the connecting rod 3213 and the second adjustment rod 322, so as to prevent the connecting rod 3213 from being separated from the second adjustment rod 322 during the adjustment process, thereby further ensuring the adjustment effect.

[0064] In the optional technical solution of this embodiment, the gear adjustment group includes a pusher 331, a first gear 332, a transmission gear 333 and two second gears 334, the outer walls of the two sliding blocks 410 are provided with racks 411, and the first gear 332, the transmission gear 333 and the two second gears 334 are rotatably connected to the inner wall of the second accommodating cavity;

[0065] The two second gears 334 are meshed with the corresponding racks 411 , one of the second gears 334 is meshed with the first gear 332 , and the other second gear 334 is meshed with the transmission gear 333 . The transmission gear 333 and the pusher 331 are meshed with the first gear 332 .

[0066] When the adjustment group is set as a gear adjustment group, the specific combination Figure 6As shown, the rack 411 is arranged on the top wall of the sliding block 410. When the adjustment component 300 adopts a gear adjustment group, the adjustment process is to push the pushing member 331 to move, the pushing member 331 is meshed with the first gear 332 for transmission, the first gear 332 rotates and meshes with the second gear 334 and the transmission gear 333, thereby driving the two second gears 334 to rotate, and because one of the second gears 334 is meshed with the first gear 332, and the other second gear 334 is connected to the first gear 332 through the transmission gear 333, the rotation directions of the two first gears 332 are opposite; in the process of the rotation of the two first gears 332, they are meshed with the corresponding rack 411, thereby driving the two sliding blocks 410 to approach or move away from each other. When the two sliding blocks 410 approach each other, the first limiting member 420 is driven to move toward the center of the adjusting inner frame 200, so that the first limiting member 420 and the second limiting member 430 are disengaged. At this time, the handle 310 is lifted upward to make the adjusting inner frame 200 move upward relative to the adjusting outer frame 100, and a height adjustment is completed; after the adjusting inner frame 200 is adjusted to the target position, the pushing member 331 is pushed in the opposite direction, so that the two sliding blocks 410 are separated from each other, and the first limiting members 420 arranged on the two sliding blocks 410 are respectively moved in the direction away from the center of the adjusting inner frame 200, so that the first limiting member 420 and the second limiting member 430 are matched again to limit the adjusting inner frame 200 to the current position, thereby avoiding the situation where the adjusting inner frame 200 falls back after adjustment, and further ensuring the adjustment effect.

[0067] In an optional technical solution of this embodiment, the height adjustment device further includes a buffer member 500 , which is disposed between the adjustment outer frame 100 and the adjustment inner frame 200 , and is connected to the first outer wall 210 of the adjustment inner frame 200 .
