DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] This embodiment discloses a dishwasher basket height adjustment device. Figure 1-3 As shown, it includes a bracket 1 and an adjustment frame 2, wherein the bracket 1 is connected between the dishwashing cavity and the bowl basket 5, a pulley 12 can be installed on the outside of the bracket 1, and a slide rail can be installed at the corresponding position of the inner wall of the dishwashing cavity to form a drawer-type structure that can roll and slide.

[0033] A connecting buckle 11 is fixedly connected to the outer side of the bracket 1. The connecting buckle 11 is interlocked with the vertical rod on the side of the bowl basket 5, so that the bowl basket 5 can be guided to slide up and down with the bracket 1, so that the bowl basket 5 can be raised and lowered under the support of the bracket 1.

[0034] The outer side of the adjustment frame 2 is fixedly connected to a number of second connecting buckles 21. These buckles 21 interlock with the horizontal and vertical bars on the side of the bowl basket 5, securing the adjustment frame 2 to the side of the bowl basket 5. An adjustment block 3 and a spring 4 are installed between the adjustment frame 2 and the bracket 1. The spring 4 elastically acts on the adjustment block 3, causing it to move sideways. This, in conjunction with the guide slots 6 on the bracket 1, allows for height adjustment between the adjustment frame 2 and the bracket 1, thereby adjusting the height of the bowl basket 5.

[0035] like Figure 3 、 4As shown, the bracket 1 has a vertical guide groove 6, with inner wall 1 601 and inner wall 2 602 on either side of the guide groove 6. The distance between inner wall 1 601 and inner wall 2 602 is the width of the guide groove 6. A plurality of vertically distributed locking grooves 61 are formed on inner wall 1 601 on one side of the guide groove 6. Generally, two sets of locking grooves 61 are provided to form two height levels.

[0036] like Figure 3 、 6 As shown, the adjustment block 3 is connected to the adjustment frame 2, and the adjustment block 3 can move relative to the adjustment frame 2. It has a first end 301 that can move relative to the width direction of the guide groove 6. The first end 301 is fixed with a locking block 32. During the movement, the adjustment block 3 can drive the locking block 32 of the first end 301 to move synchronously.

[0037] The locking block 32 is cylindrical, with an outer circumference slightly smaller than the width of the guide groove 6, and extends into the guide roller groove. During the movement of the adjustment block 3, the locking block 32 can follow the adjustment block 3 along the width of the guide groove 6, and has a first position where it abuts against the inner wall 601 and a second position where it is embedded in the locking groove 61.

[0038] The spring 4 elastically acts on the adjustment block 3, causing the adjustment block 3 and the locking block 32 to elastically move toward the inner wall 601 through the elasticity of the spring 4, achieving position limiting through the locking block 32. The locking block 32 is adjusted up and down along the guide groove 6. When the locking block 32 is in the first position, abutting against the inner wall, the bowl basket 5 can be freely raised and lowered. When the locking block 32 moves to the position of the locking groove 61, the adjustment block 3 elastically moves under the action of the spring 4, allowing the locking block 32 to be embedded in the locking groove 61. At this time, the locking block 32 is in the second position, and the locking block 32 and the locking groove 61 are locked with each other, thus supporting and limiting the bowl basket 5.

[0039] Specifically, the adjustment block 3 can be connected to the adjustment frame 2 using a rotational connection structure. A second end 302 is formed at the upper end of the adjustment block 3, and the second end 302 is rotationally connected to the adjustment frame 2 via a rotation shaft 31. The first end 301 is located above the second end 302. The first end 301 rotates about the rotation shaft 31 to move along the width of the guide slot 6.

[0040] like Figure 4As shown, the locking groove 61 has an asymmetrical structure, with a horizontal locking surface 611 on the lower side. The locking surface 611 cooperates with the locking block 32 to support the locking block 32, thereby supporting the weight of the basket 5 and its contents. The upper side of the locking groove 61 gradually expands toward the guide groove 6, forming an inclined guide surface 612. When the locking block 32 is subjected to an upward lifting force, the guide surface 612 generates a lateral force component on the locking block 32, pushing the locking block 32 away from the locking groove 61 until the locking block 32 enters the guide groove 6, thus moving the locking block 32 from the second position to the first position.

[0041] like Figure 3 、 5 As shown in Figures 7 and 8, a recessed space 22 is formed on the side of the adjustment frame 2 facing the bracket 1, and the adjustment block 3 is installed in the recessed space 22. A limiting wall 1 221 and a limiting wall 222 are formed on both sides of the recessed space 22, respectively. The limiting wall 1 221 can block and limit the rotation range of the adjustment block 3. When the locking block 32 is in the second position, the locking block 32 is stuck in the locking groove 61. At the same time, the adjustment block 3 and the limiting wall 1 221 are pressed against each other to limit the position. The lateral positioning of the locking block 32 is mainly achieved by the adjustment block 3 and the limiting wall 1 221, while the vertical limitation is mainly achieved between the locking block 32 and the locking groove 61 to maintain the position stability of the locking block 32.

[0042] A limiting groove 1 223 is provided in the middle position of the limiting wall 222, and a limiting groove 2 33 is provided in the position of the adjusting block 3 facing the limiting groove 1 223; the two ends of the spring 4 are respectively installed in the limiting groove 1 223 and the limiting groove 2 33 to support the spring 4, and the spring 4 exerts elastic pressure on the adjusting block 3 through compression elasticity, so that the adjusting block 3 is embedded in the locking groove 61 after passing through the locking groove 61 to achieve limitation.

[0043] In order to reset the adjustment frame 2 and the bracket 1, the structure of the guide groove 6 is further optimized, and the reset mechanism is used to enable the adjustment frame 2 to move downward smoothly and lower the raised bowl basket 5 again.

[0044] The width of the guide groove 6, namely the gap between the first inner wall 601 and the second inner wall 602, is greater than the locking block 32. Within the width of the guide groove 6, the locking block 32 can also move away from the first inner wall 601 and toward the second inner wall 602. In this case, the locking block 32 is in the third position. The reset mechanism locks the position of the adjustment block 3, thereby maintaining the locking block 32 in the third position. Subsequently, during the downward movement of the adjustment rack 2, the locking block 32 will not engage with the locking groove 61, allowing the locking groove 61 to freely descend and adjust, thereby resetting the height of the basket 5.

[0045] like Figure 4 As shown, a reset groove 62 is formed at the upper end of the guide groove 6. The width of the reset groove 62 matches the locking block 32, allowing the locking groove 61 to be inserted therein. The width of the reset groove 62 is smaller than that of the guide groove 6. One side is flush with the inner wall 602, while the other side is inclined to transition with the uppermost locking groove 61 via a guide surface 612. An inclined guide surface 612 is formed between the upper end of the guide groove 6, the uppermost locking groove 61, and the reset groove 62. During the upward movement of the locking block 32, it is acted upon by this guide surface 612, moving toward the guide groove 6, and the device enters the reset groove 62. At this point, the locking block 32 is in the third position.

[0046] like Figure 5 、 7 As shown in FIG-9 , the reset mechanism includes an elastic member 8, which can be an elastic sheet, elastically connected to the adjustment frame 2 and integrally formed with the adjustment frame 2. The elastic sheet can elastically deflect in the horizontal direction, and its direction corresponds to the direction of the adjustment block 3.

[0047] A clamping block 81 is fixed to the side of the elastic sheet facing the adjustment block 3. The clamping block 81 has a guiding inclined surface 811 facing the inner wall 601 and a clamping straight surface 812 facing away from the inner wall 601. A clamping block 34 is fixedly connected to the first end 301 of the adjustment block 3. When the adjustment block 3 rotates and deflects from the first position to the third position, the clamping block 34 and the guiding inclined surface 811 on the clamping block 81 press against each other, causing the push spring to produce elastic deformation until the clamping block 34 is clamped into the other side of the clamping block 81. The clamping straight surface 812 of the clamping block 81 and the clamping block 34 press against each other to limit the position, thereby clamping and fixing the position of the adjustment block 3 and maintaining the position of the locking block 32 at the third position.

[0048] Furthermore, a second clamping block 82 is fixed to the elastic member 8. The second clamping block 82 and the first clamping block 81 are located on the same side of the elastic member 8. Furthermore, the protrusion of the second clamping block 82 is higher than the protrusion of the first clamping block 81. A protrusion 7 is fixed to the side of the bracket 1 facing the adjustment block 3, which is adapted to the first clamping block 81. The protrusion 7 presses against the second clamping block 82, driving the first clamping block 81 of the elastic member 8 to disengage from the adjustment block 3. This allows the adjustment block 3 and the locking block 32 to disengage from the third position and return to the first position under the action of the spring 4.

[0049] Specifically, the protrusion 71 is located below the guide slot 6. Furthermore, when the locking block 32 moves to the lowest position of the guide slot 6, the basket 5 is adjusted to its lowest position. The protrusion abuts against the second clamping block 82, causing the elastic member 8 to elastically deform, causing the first and second clamping blocks 81 and 82 to simultaneously face away from the adjustment block 3. Because the second clamping block 82 is positioned higher, the second clamping block 82 abuts against the protrusion, allowing the first clamping block 81 and the third clamping block 34 to disengage, allowing the adjustment block 3 to elastically return to its first position under the action of the spring 4.

[0050] Furthermore, a second guiding slope 821 can be formed on the lower side of the second clamping block 82 , and the second guiding slope 821 can press against the protrusion 7 to limit the position, thereby more smoothly driving the movement of the elastic member 8 and the first and second clamping blocks 81 and 82 .

[0051] The height adjustment component of the dishwasher basket 5 can be used to adjust the height of the basket 5. In the initial state, the basket 5 is at the bottom position. Figure 12 As shown; when the height of the bowl basket 5 needs to be adjusted, the bowl basket 5 can be lifted upwards, and the bowl basket 5 can be lifted to a higher height through the adjustment component, and the height positioning of the bowl basket 5 is achieved by the mutual adaptation of the locking block 32 and the locking groove 61, and the bowl basket 5 can be lifted to different gear heights, such as Figure 11 shown.

[0052] When the basket 5 needs to be lowered again, the basket 5 can be further lifted upwards to move to the highest position, such as Figure 10 As shown, at this point, the locking block 32 will be embedded in the reset groove 62, and the locking mechanism will lock the adjustment block 3 and the locking block 32 in place. At this point, the locking block 32 is locked in the third position, allowing smooth lifting and lowering between the adjustment frame 2 and the bracket 1, allowing the basket 5 to descend. When the basket 5 descends to its lowest position, the protrusion on the inside of the bracket 1 contacts the second block 82 of the elastic member 8, driving the movement of the elastic member 8, the first block 81, and the second block 82, causing the first block 81 to disengage from the third block 34. The adjustment block 3 and the locking block 32, under the action of the spring 4, return to their first position. At this point, the basket 5 is at its lowest position, and the height of the basket 5 can be adjusted by repeating the above method.

[0053] This embodiment also discloses a dishwasher comprising a dishwasher body, with the dishwasher basket 5 height adjustment assembly of the above embodiment installed within the dishwashing chamber of the dishwasher body. This adjustment assembly allows the height of the basket 5 to be quickly adjusted during use simply by lifting the main body of the basket 5. This convenient, simple structure, and excellent stability enhance the convenience of dishwasher use.

[0054] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
