In his example, scissor-type lifting mechanism 122 also may include that there are two above scissor units 1221, for example, in carrier 11
It needs to be lifted to higher position and is just able to satisfy user it is not necessary that several scissor units 1221 when bending over to operate, can be mostly used mutually
Connection to promote the lifting height of carrier 11, specific quantity can according to the actual situation depending on.
It should be noted that referring to Fig. 3, above-mentioned " fixed part 123 and moving portion 124 and scissor-type lifting mechanism 122
Lower end rotation connection " refers to the lower end of the first connecting rod 12211 of the scissor unit 1221 positioned at 122 lower end of scissor-type lifting mechanism
It is rotatablely connected with fixed part 123, positioned at the second connecting rod 12212 of the scissor unit 1221 of 122 lower end of scissor-type lifting mechanism
Lower end and moving portion 124 are rotatablely connected.In Fig. 3, it will be understood that in order to guarantee scissor-type lifting mechanism 122 can normally,
Steadily work, the first connecting rod 12211 of lower end and the second connecting rod 12212 and moving portion of 123 junction of fixed part and lower end
124 junction is generally within sustained height position.
In addition, in the present embodiment, executive item 13 wears fixed part 123 and moving portion 124, it can be relative to fixed part
123 and moving portion 124 rotate.Moving portion 124 is formed with threaded hole, and screw thread is formed on executive item 13, and executive item 13 wears spiral shell
Pit is simultaneously threadedly coupled with moving portion 124.The position that executive item 13 wears fixed part 123 is not formed with screw thread, therefore, executes
Part 13 can rotate relative to fixed part 123 and fixed part 123 will not be driven mobile.Specifically, this implementation executive item 13 can be with
It is screw rod, threaded hole is formed in moving portion 124, executive item 13 and moving portion 124 are threadedly coupled, when executive item 13 rotates,
Executive item 13 can drive moving portion 124 to move on executive item 13.In moving portion 124 when being moved on executive item 13,
Driving scissor-type lifting mechanism 122 drives carrier 11 to rise or fall.
Fig. 3 to Fig. 6 is please referred to, in some embodiments, lifting assembly 12 further includes support frame 125, and support frame 125 is set
It is placed in the upper end of scissor-type lifting mechanism 122, carrier 11 is set to support frame 125.
In this way, support frame 125 can guarantee the stability of carrier 11 when carrier 11 rises or falls, prevent from carrying
Object 11 shake it is excessive, to avoid the occurrence of unstable or even the phenomenon that fall.
In addition, in above embodiment, lifting assembly 12 further includes fixed block 126 and sliding block 127, fixed block 126 and sliding
Block 127 is rotatablely connected with the upper end of scissor-type lifting mechanism 122 respectively, and fixed block 126 is fixedly connected with support frame 125, is supported
Frame 125 offers sliding slot 1251, and sliding block 127 is set to sliding slot 1251, drives carrier 11 to rise in scissor-type lifting mechanism 122
Or during decline, sliding block 127 slides in sliding slot 1251.
It should be noted that please refer to Fig. 3 and Fig. 6, it is above-mentioned " fixed block 126 and sliding block 127 respectively with fork type elevator
The upper end rotation connection of structure 122 " refers to the first connecting rod of the scissor unit 1221 positioned at 122 upper end of scissor-type lifting mechanism
12211 upper end and sliding block 127 are rotatablely connected, and second positioned at the scissor unit 1221 of 122 upper end of scissor-type lifting mechanism connects
The upper end of bar 12212 and fixed block 126 are rotatablely connected.In addition, such as Fig. 3, in order to guarantee carrier can smoothly rise and under
The connection of the junction of the second connecting rod 12212 of drop, fixed block 126 and upper end and sliding block 127 and the first connecting rod 12211 of upper end
Place is generally within sustained height position.
Specifically, Fig. 3 and Fig. 4 are please referred to, in the present embodiment, when needing to promote carrier 11, electric drive assembly
14 driving executive items 13 rotate, and executive item 13 drives moving portion 124 mobile to the direction where fixed part 123, moving portion 124 with
The distance between fixed part 123 shortens, at this point, scissor-type lifting mechanism 122 starts to spread out, cunning of the sliding block 127 in support frame 125
Mobile to the direction where fixed block 126 in slot 1251, with the expansion of scissor-type lifting mechanism 122, carrier 11 is with branch
Support 125 is lifted up together, and at the highest point of rising (as shown in Figure 3), electric drive assembly 14 stops driving executive item 13
Rotation, moving portion 124 stop movement.It is understood that in the present embodiment, fixed part 123 can be fixed by screw
It is mounted on pedestal 121, is also possible to directly weld or be riveted on pedestal 121.
When needing to fall carrier 11, electric drive assembly 14 drives executive item 13 to rotate, the driving movement of executive item 13
Portion 124 is mobile to the direction far from fixed part 123, the distance between moving portion 124 and fixed part 123 side length, at this point, scissor-type
Elevating mechanism 122 starts to shrink, and sliding block 127 moves in the sliding slot 1251 of support frame 125 to far from the direction where fixed block 126
Dynamic, with the contraction of scissor-type lifting mechanism 122, carrier 11 declines together with support frame 125, when dropping to minimum point
(as shown in Figure 4), electric drive assembly 14 stop driving executive item 13 and rotate, and moving portion 124 stops movement.
It is understood that in the present embodiment, when needing to promote carrier 11, the driving of electric drive assembly 14 is executed
Part 13 rotates forward, and when needing to fall carrier 11, electric drive assembly 14 drives executive item 13 to invert.In other embodiments
In, it is also possible to when needing to promote carrier 11, electric drive assembly 14 drives executive item 13 to invert, and is needing carrier 11
When falling, electric drive assembly 14 drives executive item 13 to rotate forward, specifically with no restriction.
Fig. 1 and Fig. 2 are please referred to, in one example, household electrical appliance 100 are dish-washing machine, and above-mentioned cavity 20 is dish-washing machine
Liner, above-mentioned carrier 11 are bowl basket, and as depicted in figs. 1 and 2, dish-washing machine further includes ontology 30 and guide assembly 40, guide rail group
Part 40, which connects liner and ontology 30, liner, can be skidded off or be slid into ontology 30 by guide assembly 40.In the present embodiment, with
When family needs to carry out dishwashing detergent, user pulls out liner out of ontology 30 first, and then, electric drive assembly 14 drives executive item
13 rotations are to drive scissor-type lifting mechanism 122 that carrier 11 is driven to rise, and after rising to highest point, electric drive assembly 14 stops
Driving, user put tableware on carrier 11.Then, electric drive assembly 14 drives the rotation of executive item 13 to drive scissor again
Formula elevating mechanism 122 drives carrier 11 to decline, and after dropping to minimum point, electric drive assembly 14 stops driving, at this point, user can
Liner to be pushed into ontology 30, start to be washed.After having washed, pick and place tableware when workflow with above-mentioned process class
Seemingly, repetition elaboration is not done herein.It is understood that in other examples, household electrical appliance 100 are also possible to cleaning machine, disinfection
The household electrical appliance such as cabinet 100, specific workflow is similar, does not do repetition elaboration herein.It is understood that in present embodiment
In, lifting device 10 is mounted on liner, and when liner skids off or releases ontology 30, lifting device 10 can also follow liner to skid off
Or release ontology 30.
Fig. 3 and Fig. 4 are please referred to, in some embodiments, lifting device 10 further includes locating part 16, locating part 16 and bottom
Seat 121 is fixedly connected, and between locating part 16 and fixed part 123, executive item 13 wears locating part 16 and can moving portion 124
It is rotated relative to locating part 16, the position that moving portion 124 is capable of executive item 13 between locating part 16 and fixed part 123 moves up
It is dynamic.Specifically, referring to Fig. 3, in Fig. 3, executive item 13 is screw rod, and locating part 16 and fixed part 123 are located at screw rod
