[0033] Reference Figure 1 、 Figure 2 and Figure 3 , a bowl and basket lifting device, comprising:

[0034] Fixed lifting assembly 1;

[0035] The limiting assembly 3 is slidably connected to the fixed lifting assembly 1 along the vertical direction. The vertical direction is the direction in which the two sets of bowl baskets arranged up and down translate. The limiting assembly 3 is provided with a high-position limiting hole 32 and a low-position limiting hole 33 on the side facing the fixed lifting assembly 1;

[0036] The plug-in assembly includes an elastic member 5 and a plug-in block 4. The plug-in block 4 is connected to the side of the fixed lifting assembly 1 facing the limit assembly 3 through the elastic member 5. The side of the plug-in block 4 facing the limit assembly 3 is provided with a protrusion 6 that can be engaged with the high limit hole 32 or the low limit hole 33;

[0037] The handle 2 is rotatably connected to the fixed lifting assembly 1 , and one end of the handle abuts against a side of the plug-in block 4 facing the limiting assembly 3 .

[0038] Obviously, based on the above, by rotating the handle 2 to squeeze the plug-in block 4 toward the side of the fixed lifting component 1, the protrusion 6 is disengaged from the limiting hole, so that the plug-in block 4 can move up and down along the limiting component 3 to switch between the high-position limiting hole 32 and the low-position limiting hole 33, thereby the fixed lifting component 1 connected to the bowl basket can drive the bowl basket to move up and down.

[0039] In this embodiment, referring to Figure 2 and Figure 3 A guide slope is provided on the side of the protrusion 6 away from the handle 2 , and the limiting hole 33 can cooperate with the guide slope to enable the plug-in block 4 to move toward the fixed lifting assembly 1 .

[0040] Obviously, based on the above, when the protrusion 6 switches from the low-position limit hole 33 to the high-position limit hole 32, it is only necessary to pull the bowl basket by hand, and the bowl basket drives the limit mounting block 31 to move upward, thereby the guiding inclined surface of the protrusion 6 acts on the lower side of the low-position limit hole 33, the protrusion 6 is separated from the low-position limit hole 33, and the bowl basket moves upward to drive the protrusion 6 into the high-position limit hole 32 to complete the fixation.

[0041] In this embodiment, referring to Figure 2 、 Figure 3 and Figure 6 The limiting assembly 3 includes a limiting mounting block 31, a first slide groove 34 is opened on the limiting mounting block 31, a high-position limiting hole 32 and a low-position limiting hole 33 are arranged at the bottom of the first slide groove 34, and the groove wall of the first slide groove 34 is slidably connected to the fixed lifting assembly 1.

[0042] Obviously, based on the above, the fixed lifting assembly 1 can slide along the first sliding groove 34 , thereby realizing the switching of the fixed position of the protrusion 6 between the high-position limiting hole 32 and the low-position limiting hole 33 .

[0043] In this embodiment, referring to Figure 2 、 Figure 3 and Figure 4 The fixed lifting assembly 1 includes a connecting member 13 and a fixed rod 11. The connecting member 13 is provided with a hinge groove 14. One end of the handle 2 is placed in the hinge groove 14 and hinged to the side wall of the hinge groove 14. The plug-in block 4 is connected to the bottom of the hinge groove 14 through the elastic member 5.

[0044] Obviously, based on the above, the plug-in block 4 can move along the side wall of the hinge groove 14 close to the fixed lifting component 1 under the action of the extrusion force. When the extrusion force disappears, the plug-in block 4 moves along the side away from the fixed lifting component 1 under the action of the elastic member 5.

[0045] In this embodiment, referring to Figure 4 and Figure 6 The connecting member 13 also includes a second slide groove 16 arranged on both sides of the hinge groove 14, and a slide rail 35 is provided on the outer side walls of both sides of the first slide groove 34, and the slide rail 35 is slidably connected to the second slide groove 16.

[0046] Obviously, based on the above, the second sliding groove 16 is provided to enhance the stability of the fixed lifting assembly 1 when sliding along the limiting assembly 3 .

[0047] In this embodiment, referring to Figure 2 、 Figure 3 and Figure 5 A connecting hole 12 is provided at the upper end of the connecting member 13, and the handle 2 is rotatably connected to the connecting member 13 through the connecting hole 12. The handle 2 includes a handle body 21, a rotating shaft 22 and an extrusion portion 23 that are integrally connected. The extrusion portion 23 is arranged at the lower end of the handle body 21, and the lower part of the extrusion portion 23 abuts against the plug-in assembly. The rotating shaft 22 is installed at the upper end of the extrusion portion 23, and the rotating shaft 22 is rotatably connected to the connecting hole 12.

[0048] Obviously, based on the above, by rotating the hand-held handle body 21 , the squeezing portion 23 directly acts on the plug-in block 4 to provide power for the protrusion 6 to escape from the limiting hole.

[0049] In this embodiment, referring to Figure 2 、 Figure 3 and Figure 5 A transition portion 24 is connected between the extrusion portion 23 and the lower end of the handle body 21 , and a preset angle is formed between the transition portion 24 and the extrusion portion 23 ;

[0050] Specifically, the transition portion 24 allows the two sides of the extrusion portion 23 to respectively contact and fix with the inner wall of the slide groove 34 and the plug-in block 4 when the protrusion 6 is located in the limiting hole, and the extrusion portion 23 is in a vertical state.

[0051] Obviously, the protrusion 6 is in the limiting hole, and under the action of the elastic member 5 and the supporting force of the inner wall of the slide groove 34, the extrusion portion 23 is restricted and fixed, thereby the handle body 21 is fixed without the action of external force.

[0052] In this embodiment, referring to Figure 2 and Figure 3 When the protrusion 6 is located in the limiting hole, the transition portion 24 is in a horizontal state, and the connection between the lower end of the handle body 21 and the transition portion 24 is in a vertical state.

[0053] Obviously, based on the above, it is convenient to apply external force by holding the handle body 21, which is convenient for use.

[0054] In this embodiment, referring to Figure 5 The surface of the handle body 21 is provided with anti-slip protrusions.

[0055] Obviously, based on the above, the provision of the anti-slip protrusions increases the friction of the handheld portion, thereby preventing the handle 2 from detaching when an external force is applied, thereby preventing the dishes in the bowl basket from being damaged.

[0056] In this embodiment, referring to Figure 2 and Figure 3 The elastic member 5 is a spring.

[0057] Obviously, based on the above, setting the elastic member 5 as a spring simplifies the structure and reduces costs.

[0058] In this embodiment, referring to Figure 4 A limiting plate 15 is installed on the outer side of the lower end of the elastic member extrusion groove 14 to prevent the slider 4 from separating, and the limiting block 15 is L-shaped.

[0059] Obviously, based on the above, the slider 4 is confined in the elastic member extrusion groove 14 .

[0060] Secondly, refer to Figure 1 、 Figure 6 and Figure 7 The utility model provides a dishwasher, comprising a barrel, a bowl basket and any one implementation scheme of the above-mentioned bowl basket lifting device.

[0061] In this embodiment, the basket lifting device includes a limiting assembly 3 connected to the basket, and the basket lifting device includes a fixed lifting assembly 1 slidably connected to the inner wall of the barrel. The basket lifting device is installed on one side of the basket in the direction of pulling.

[0062] A first fixing hole 36 is formed at the upper end of the limiting assembly 3, which is engaged with the ribs of the basket. A fixing member mounting block 8 is provided on the side of the fixed lifting assembly 1 near the limiting assembly 3. A basket fixing member 7 is provided on the side of the fixing member mounting block 8 near the limiting assembly 3. The basket fixing member 7 can slide up and down along the fixing member mounting block 8. A second fixing hole is formed at the upper end of the basket fixing member 7, which is connected to the ribs of the basket.

[0063] A roller mounting shaft 9 is installed on the side of the fixed lifting component 1 away from the limiting component 3. A roller is sleeved on the outer side of the roller mounting shaft 9, and a roller groove adapted to the roller is opened on the inner side wall of the dishwasher body.

[0064] Obviously, based on the above, the bowl basket can be pulled out from the dishwasher body by the roller. When the bowl basket switches from the high position to the low position, the protrusion 6 is separated from the high-position limit hole 32 by rotating the handle 2. Under the action of gravity, the limit assembly 3 moves downward so that the protrusion 6 enters the low-position limit hole 33 and is fixed. When the bowl basket switches from the low position to the high position, the portable bowl basket moves upward, and the bowl basket drives the limit assembly 3 to move upward. As a result, the guiding inclined surface of the protrusion 6 acts on the lower side of the low-position limit hole 33, and the protrusion 6 separates from the low-position limit hole 33. The bowl basket moves upward and drives the protrusion 6 into the high-position limit hole 32 to complete the fixation.

[0065] This makes it possible to adjust the fixed height of the bowl basket, making it convenient for users to adjust the installation height of the bowl basket according to the size of the bowls and dishes.

[0066] In order to more clearly illustrate the scheme and effect of this implementation, the following examples are provided with reference to the accompanying drawings:

[0067] Reference Figure 1-Figure 7 , when the basket lifting device is in the low position and switches to the high position:

[0068] When the user moves the basket upward, the basket drives the limit mounting block 31 upward. The guiding slope of the protrusion 6 acts on the lower side of the low-position limit hole 33, and the protrusion 6 separates from the low-position limit hole 33. The basket moves upward and drives the protrusion 6 into the high-position limit hole 32. At this time, the basket is fixed, and the basket is switched from the low position to the high position.

[0069] When the basket lifting device is in the high position and switches to the low position:

[0070] The user rotates the handle body 21, and the protrusion 6 separates from the high-position limit hole 32. Under the action of gravity, the limit mounting block 31 moves downward so that the protrusion 6 enters the low-position limit hole 33. At this time, the bowl basket is fixed, and the bowl basket is switched from the high position to the low position.
